| 2 | Insulin-like growth factor(IGF)signaling in tumorigenesis and the development of cancer drug resistance显示文摘One of the greatest obstacles to current cancer treatment efforts is the development of drug resistance by tumors.Despite recent advances in diagnostic practices and surgical interventions,many neoplasms demonstrate poor response to adjuvant or neoadjuvant radiation and chemotherapy.As a result,the prognosis for many patients afflicted with these aggressive cancers remains bleak.The insulin-like growth factor(IGF)signaling axis has been shown to play critical role in the development and progression of various tumors.Many basic science and translational studies have shown that IGF pathway modulators can have promising effects when used to treat various malignancies.There also exists a substantial body of recent evidence implicating IGF signaling dysregulation in the dwindling response of tumors to current standard-of-care therapy.By better understanding both the IGF-dependent and-independent mechanisms by which pathway members can influence drug sensitivity,we can eventually aim to use modulators of IGF signaling to augment the effects of current therapy.This review summarizes and synthesizes numerous recent investigations looking at the role of the IGF pathway in drug resistance.We offer a brief overview of IGF signaling and its general role in neoplasia,and then delve into detail about the many types of human cancer that have been shown to have IGF pathway involvement in resistance and/or sensitization to therapy.Ultimately,our hope is that such a compilation of evidence will compel investigators to carry out much needed studies looking at combination treatment with IGF signaling modulators to overcome current therapy resistance. | Sahitya K.Denduluri Olumuyiwa Idowu Zhongliang Wang Zhan Liao Zhengjian Yan Maryam K.Mohammed Jixing Ye Qiang Wei Jing Wang Lianggong Zhao Hue H.Luu | 2015 | Genes & Diseases2015,2,1: | 21 |
| 3 | Clinical trial with traditional Chinese medicine intervention ''tonifying the kidney to promote liver regeneration and repair by affecting stem cells and their microenvironment'' for chronic hepatitis B-associated liver failure显示文摘AIM:To study the clinical efficacy of traditional Chinese medicine(TCM)intervention'tonifying the kidney to promote liver regeneration and repair by affecting stem cells and their microenvironment'('TTK')for treating liver failure due to chronic hepatitis B.METHODS:We designed the study as a randomized controlled clinical trial.Registration number of Chinese Clinical Trial Registry is Chi CTR-TRC-12002961.A total of 144 patients with liver failure due to infection with chronic hepatitis B virus were enrolled in this randomized controlled clinical study.Participants were randomly assigned to the following three groups:(1)a modern medicine control group(MMC group,36patients);(2)a'tonifying qi and detoxification'('TQD')group(72 patients);and(3)a'tonifying the kidney to promote liver regeneration and repair by affecting stem cells and their microenvironment'('TTK')group(36patients).Patients in the MMC group received general internal medicine treatment;patients in the'TQD'group were given a TCM formula'tonifying qi and detoxification'and general internal medicine treatment;patients in the'TTK'group were given a TCM formula of'TTK'and general internal medicine treatment.All participants were treated for 8 wk and then followed at 48 wk following their final treatment.The primaryefficacy end point was the patient fatality rate in each group.Measurements of various virological and biochemical indicators served as secondary endpoints.The one-way analysis of variance and the t-test were used to compare patient outcomes in the different treatment groups.RESULTS:At the 48-wk post-treatment time point,the patient fatality rates in the MMC,'TQD',and'TTK'groups were 51.61%,35.38%,and 16.67%,respectively,and the differences between groups were statistically significant(P<0.05).However,there were no significant differences in the levels of hepatitis B virus DNA or prothrombin activity among the three groups(P>0.05).Patients in the'TTK'group had significantly higher levels of serum total bilirubin compared to MMC subjects(339.40μmol/L±270.09μmol/L vs 176.13μmol/L±185.70μmol/L,P=0.014).Serum albumin levels were significantly increased in both the'TQD'group and'TTK'group as compared with the MMC group(31.30 g/L±4.77g/L,30.72 g/L±2.89 g/L vs 28.57 g/L±4.56 g/L,P<0.05).There were no significant differences in levels of alanine transaminase among the three groups(P>0.05).Safety data showed that there was one case of stomachache in the'TQD'group and one case of gastrointestinal side effect in the'TTK'group.CONCLUSION:Treatment with'TTK'improved the survival rates of patients with liver failure due to chronic hepatitis B.Additionally,liver tissue was regenerated and liver function was restored. | Han-Min Li Zhi-Hua Ye Jun Zhang Xiang Gao Yan-Ming Chen Xin Yao Jian-Xun Gu Lei Zhan Yang Ji Jian-Liang Xu Ying-He Zeng Fan Yang Lin Xiao Guo-Guang Sheng Wei Xin Qi Long Qing-Jing Zhu Zhao-Hong Shi Lian-Guo Ruan Jia-Yao Yang Chang-Chun Li Hong-Bin Wu Sheng-Duo Chen Xin-La Luo | 2014 | World Journal of Gastroenterology2014,20,48: | 20 |
| 4 | Comprehensive treatments for hepatocellular carcinoma with tumor thrombus in major portal vein显示文摘AIM: To evaluate the efficacy of transcatheter arterial chemoembolisation(TACE) compared with surgical intervention and sorafenib for treatment of hepatocellular carcinoma(HCC) in patients with tumor thrombus extending to the main portal vein.METHODS: From 2009 to 2013, a total of 418 HCC patients with tumor thrombus extending to the main portal vein were enrolled in this study and divided into four groups. These groups underwent different treatments as follows: TACE(n = 307), surgical intervention(n = 54), sorafenib(n = 15) and palliativetreatment(n = 42). Overall survival rates were determined by Kaplan-Meier method, and differences between the groups were identified through log-rank analysis. Cox's proportional hazard model was used to identify the risk factors for survival.RESULTS: The mean survival periods for patients in the TACE, surgical intervention, sorafenib and palliative treatment groups were 10.39, 4.13, 5.54 and 2.82 mo, respectively. For the TACE group, the 3-, 6-, 12-and 24-mo survival rates were 94.1%, 85.9%, 51.5% and 0.0%, respectively. The corresponding rates were 60.3%, 22.2%, 0.0% and 0.0% for the surgical intervention group and 50.9%, 29.5%, 0.0% and 0.0% for the sorafenib group. Evidently, the results in the TACE group were significantly higher than those in the other groups(P < 0.0001). Furthermore, no significant difference among survival rates was observed between TACE with/without sorafenib(10.22 mo vs 10.52 mo, P = 0.615). No significant difference in survival rates was also found among the surgical intervention, sorafenib and palliative treatment groups(P > 0.05). These values significantly increased after TACE with/without sorafenib compared with other treatments(P < 0.05).CONCLUSION: For HCC patients with tumor thrombus extending to the main portal vein, TACE can yield a higher survival rate than surgical intervention or sorafenib treatment. | Hai-Hong Ye Jia-Zhou Ye Zhi-Bo Xie Yu-Chong Peng Jie Chen Liang Ma Tao Bai Jun-Ze Chen Zhan Lu Hong-Gui Qin Bang-De Xiang Le-Qun Li | 2016 | World Journal of Gastroenterology2016,22,13: | 14 |
| 5 | LUCC and its impact on run-off yield in the Bai River catchment—upstream of the Miyun Reservoir basin显示文摘Aims The Miyun Reservoir is the most important drinking water source for Beijing—the capital of China with a population of more than 16 million.Since the 1980s,the inflow to the reservoir has been decreasing,which seriously threatens the security of water use in Beijing.Our goal was to analyze the impact of land use and cover change(LUCC)on run-off yield in the upstream of the Miyun Reservoir.Methods In this study,the Soil andWater Assessment Tool(SWAT)was used to simulate the impacts of LUCC on the run-off yield in the Bai River catchment—upstream of the Miyun Reservoir basin in northern China.The investigation was conducted using two 6-year historical streamflow records:from 1986 to 1991 and from 2000 to 2005.A split sample procedure was used for model calibration and validation.The data from 1986 to 1988 and from 2000 to 2002 were used for calibration,while those from 1989 to 1991 and from 2003 to 2005 for validation.The SWAT calibration was based on monthly measured discharge at Zhangjiafen station at the catchment outlet from Bai River catchment.Additionally,the influence of LUCC on the surface run-off was distinguished from that of climate change on the surface runoff through SWAT scenarios modeling,the twoway analysis of variance(ANOVA),and the rainfall–run-off double-mass analysis in the Bai River catchment.Important Findings We found that the SWAT model could be used successfully to accurately simulate run-off yield and different LUCC patterns affecting water quantity in this catchment.During calibraion for the two periods the simulated monthly run-off satisfactorily matched the observed values,with the Nash–Sutcliffe coefficient>0.9 and 0.7 and a coefficient of determination of 0.9 and 0.65 at the outlet station(Zhangjiafen station),while during validation for the two periods the obtained values were 0.85,0.65 and 0.9,0.65,respectively.During the period of 1986–91,both the SWAT scenarios modeling and the analysis of the two-way ANOVA method showed that LUCC and climate change had some impact on run-off,and the impact of climate change was more significant than that of LUCC.Compared with the period during 1986–91,the run-off yield in the period during 2000–05 significantly decreased.The obtained results from the rainfall–run-off double-mass analysis indicate that since 1998 LUCC has had an increasing influence on the run-off,while the response of the run-off to rainfall has been decreasing.Since 1998,the LUCC has been a major driving force for run-off change in Bai River catchment. | Chesheng Zhan Zongxue Xu Aizhong Ye Hongbo Su | 2011 | Journal of Plant Ecology2011,4,1: | 12 |
| 6 | Hangzhou criteria as downstaging criteria in hepatocellular ca显示文摘Background:The downstaging of hepatocellular carcinoma(HCC)has been confirmed to benefit liver transplantation(LT)patients whose tumors are beyond the transplantation criteria.Milan criteria(MC),a tumor size and number-based assessment,is currently used as the endpoint in these patients.However,many studies believe that tumor biological behavior should be added to the evaluation criteria for downstaging efficacy.Hence,this study aimed to explore the feasibility of Hangzhou criteria(HC),which introduced tumor grading and alpha-fetoprotein in addition to tumor size and number,as an endpoint of downstaging.Methods:We performed a multicenter and retrospective study of 206 patients accepted locoregional therapy(LRT)as downstaging/bridge treatment prior to LT in three centers of China.Results:Recipients were divided into four groups:failed downstaging to the HC(group A,n=46),successful downstaging to the HC(group B,n=30),remained within the HC all the time(group C,n=113),and tumor progressed(group D,n=17).The 3-year HCC recurrence probabilities of groups B and C were not significantly different(10.3%vs.11.6%,P=0.87).The HCC recurrent rate was significantly higher in group A(52.3%)compared with that in group B/C(P<0.05).Seven patients(7/76,9.2%)whose tumor exceeded the the HC were successfully downstaged to the MC,and 39.5%(30/76)to the the HC.In group B,23 patients remained beyond the MC and their survivals were as well as those of patients within the MC.Conclusions:Compared to the MC,HC downstaging criteria can give more HCC patients access to LT and furthermore,the outcome of these patients is the same as those matching MC downstaging criteria.Hangzhou downstaging criteria therefore is applicable in clinical practice. | Qi-Fan Zhan Sun-Bin Ling Yi-Nan Deng Qiao-Nan Shan Qian-Wei Ye Sheng-Jun Xu Guang-Jiang Jiang Di Lu Xu-Yong Wei Li Zhuang Wu Zhang Tian Shen Bei-Ni Cen Hai-Yang Xie Ji-Min Liu Jian Wu Shu-Sen Zheng Yang Yang Xiao Xu | 2020 | Hepatobiliary & Pancreatic Diseases International2020,19,4: | 11 |
| 7 | Predictive model for acute abdominal pain after transarterial chemoembolization for liver cancer显示文摘BACKGROUND Transarterial chemoembolization(TACE)is the first-line treatment for patients with unresectable liver cancer;however,TACE is associated with postembolization pain.AIM To analyze the risk factors for acute abdominal pain after TACE and establish a predictive model for postembolization pain.METHODS From January 2018 to September 2018,all patients with liver cancer who underwent TACE at our hospital were included.General characteristics;clinical,imaging,and procedural data;and postembolization pain were analyzed.Postembolization pain was defined as acute moderate-to-severe abdominal pain within 24 h after TACE.Logistic regression and a classification and regression tree were used to develop a predictive model.Receiver operating characteristic curve analysis was used to examine the efficacy of the predictive model.RESULTS We analyzed 522 patients who underwent a total of 582 TACE procedures.Ninety-seven(16.70%)episodes of severe pain occurred.A predictive model built based on the dataset from classification and regression tree analysis identified known invasion of blood vessels as the strongest predictor of subsequent performance,followed by history of TACE,method of TACE,and history of abdominal pain after TACE.The area under the receiver operating characteristic curve was 0.736[95%confidence interval(CI):0.682-0.789],the sensitivity was 73.2%,the specificity was 65.6%,and the negative predictive value was 92.4%.Logistic regression produced similar results by identifying age[odds ratio(OR)=0.971;95%CI:0.951-0.992;P=0.007),history of TACE(OR=0.378;95%CI:0.189-0.757;P=0.007),history of abdominal pain after TACE(OR=6.288;95%CI:2.963-13.342;P<0.001),tumor size(OR=1.978;95%CI:1.175-3.330;P=0.01),multiple tumors(OR=2.164;95%CI:1.243-3.769;P=0.006),invasion of blood vessels(OR=1.756;95%CI:1.045-2.950;P=0.034),and TACE with drug-eluting beads(DEBTACE)(OR=2.05;95%CI:1.260-3.334;P=0.004)as independent predictive factors for postembolization pain.CONCLUSION Blood vessel invasion,TACE history,TACE with drug-eluting beads,and history of abdominal pain after TACE are predictors of acute moderate-to-severe pain.The predictive model may help medical staff to manage pain. | Li-Fang Bian Xue-Hong Zhao Bei-Lei Gao Sheng Zhang Guo-Mei Ge Dong-Di Zhan Ting-Ting Ye Yan Zheng | 2020 | World Journal of Gastroenterology2020,26,30: | 11 |
| 8 | Donepezil attenuates vascular dementia in rats through increasing BDNF induced by reducing HDAC6 nuclear translocation显示文摘Vascular dementia(VD)is the second most common dementia disease after Alzheimer’s diseases(AD)in the world.Donepezil is used to treat mild to moderate AD,and it has been shown to treat cognitive impairment and memory deficits caused by VD.However,the action mechanism of donepezil against VD has not been clarified.In this study,a bilateral common carotid artery occlusion(BCCAO)model was established in rats to simulate the pathology of VD.Two weeks after the surgery,the rats were administered donepezil(10 mg·kg^−1·d^−1,ig)for 3 weeks,and then subjected to behavioral tests.We showed that donepezil treatment significantly improved the performance of BCCAO rats in Morris Water Mazes test and Step-down test.Furthermore,we showed that donepezil treatment significantly attenuated neurodegeneration and restored the synapse dendritic spines density in cortex and hippocampus.We revealed that donepezil treatment significantly increased BDNF expression in cortex and hippocampus.Interestingly,donepezil treatment significantly decreased nuclear translocation of HDAC6 and the binding between HDAC6 and BDNF promoter IV in cortex,but not in the hippocampus.The attenuated neurodegeneration by donepezil in cortex and hippocampus might due to the reduced ROS levels and increased phosphorylation of AMPK,whereas increased phosphorylation of AKT was only detected in cortex.In conclusion,our results demonstrate that donepezil attenuates neurodegeneration in cortex and hippocampus via increasing BDNF expression;the regulation of donepezil on HDAC6 occurred in cortex,but not in the hippocampus.This study further clarifies the pharmacological mechanism of donepezil,while also emphasizes the promising epigenetic regulation of HDAC6. | Wen-xuan Jian Zhao Zhang Jia-hong Zhan Shi-feng Chu Ye Peng Ming Zhao Qi Wang Nai-hong Chen | 2020 | Acta Pharmacologica Sinica2020,41,5: | 9 |
| 9 | Multicenter study of the clinicopathological features and recurrence risk prediction model of early-stage breast cancer with low-positive human epidermal growth factor receptor 2 expression in China (Chinese Society of Breast Surgery 021)显示文摘Background:Breast cancer with low-positive human epidermal growth factor receptor 2(HER2)expression has triggered further refinement of evaluation criteria for HER2 expression.We studied the clinicopathological features of early-stage breast cancer with low-positive HER2 expression in China and analyzed prognostic factors.Methods:Clinical and pathological data and prognostic information of patients with early-stage breast cancer with low-positive HER2 expression treated by the member units of the Chinese Society of Breast Surgery and Chinese Society of Surgery of Chinese Medical Association,from January 2015 to December 2016 were collected.The prognostic factors of these patients were analyzed.Results:Twenty-nine hospitals provided valid cases.From 2015 to 2016,a total of 25,096 cases of early-stage breast cancer were treated,7642(30.5%)of which had low-positive HER2 expression and were included in the study.After ineligible cases were excluded,6486 patients were included in the study.The median follow-up time was 57 months(4-76 months).The disease-free survival rate was 92.1%at 5 years,and the overall survival rate was 97.4%at 5 years.At the follow-up,506(7.8%)cases of metastasis and 167(2.6%)deaths were noted.Multivariate Cox regression analysis showed that tumor stage,lymphvascular invasion,and the Ki67 index were related to recurrence and metastasis(P<0.05).The recurrence risk prediction model was established using a machine learning model and showed that the area under the receiving operator characteristic curve was 0.815(95%confidence interval:0.750-0.880).Conclusions:Early-stage breast cancer patients with low-positive HER2 expression account for 30.5%of all patients.Tumor stage,lymphvascular invasion,and the Ki67 index are factors affecting prognosis.The recurrence prediction model for breast cancer with low-positive HER2 expression based on a machine learning model had a good clinical reference value for predicting the recurrence risk at 5 years.Trial registration:ChiCTR.org.cn,ChiCTR2100046766. | Ling Xin Qian Wu Chongming Zhan Hongyan Qin Hongyu Xiang Ling Xu Jingming Ye Xuening Duan Yinhua Liu Chinese Society of Breast Surgery(CSBrS) Chinese Society of Surgery of Chinese Medical Association | 2022 | Chinese Medical Journal2022,,6: | 9 |

| 11 | Effects of Niaoduqing Particles(尿毒清颗粒)on Delaying Progression of Renal Dysfunction:A Post-trial,Open-Label,Follow-up Study显示文摘Objective: To follow up the participants of the randomized clinical trial 'Efficacy and Safety of Niaoduqing Particles(尿毒清颗粒) for Delaying Moderate-to-Severe Renal Dysfunction', and assess the long-term effects of Niaoduqing Particles on delaying the progression of renal dysfunction. Methods: Participants, who had previously been randomly assigned to receive Niaoduqing Particles or placebo for 24 weeks(146 cases in each group), were invited to follow-up and all were administered Niaoduqing Particles 5 g thrice daily and 10 g before bedtime for 24 weeks. The primary endpoints were changes in baseline serum creatinine(Scr) and estimated glomerular filtration rate(e GFR) after completion of the open-label treatment period. Results: After the double-blind period, the median(interquartile range) changes in Scr were 1.1(–13.0–24.1) and 11.7(–2.6–42.9) μmol/L for the Niaoduqing Particle and placebo groups, respectively(P=0.008), and the median changes in e GFRs were –0.2(–4.3–2.7) and –2.21(–5.7–0.8) mL·min^(-1)·1.73 m^(-2), respectively(P=0.016). There were significant differences in the double-blind period changes in renal function between groups. After the open-label period, the median changes in Scr were 9.0(–10.0–41.9) and 17.5(–6.0–50.0) μmol/L for the Niaoduqing Particle and placebo groups according to baseline grouping, respectively(P=0.214), and the median changes in eGFRs were –2.3(–6.4–1.9) and –3.7(–7.5–1.1) mL·min^(-1)·1.73 m^(-2), respectively(P=0.134). There were no statistical differences in the open-label period changes in renal function between groups. The eGFR reduction of participants who accepted Niaoduqing Particle treatment for 48 weeks was projected to 2.5 m L·min^(-1)·1.73 m(-2) per year. Conclusions: Niaoduqing Particles appear to have long-term efficacy for patients with moderate-to-severe renal dysfunction. Although there was no statistical difference, the early use of Niaoduqing Paticles seems to ameliorate the worsening of renal function. | ZHENG Ying WANG Nian-song LIU Yu-ning HE Li-qun JIAN Gui-hua LIU Xu-sheng NI Zhao-hui CHENG Xiao-hong LIN Hong-li ZHOU Wen-hua WANG Ya-ping FANG Jing-ai HE Ya-ni YANG Hong-tao ZHAO Li-juan DING Han-lu WANG Li-hua YU Ren-huan LI Wen-ge YE Zhi-ming GUO Wang ZHAN Yong-li MAO Hui-juan HU Zhao YAO Chen CAI Guang-yan CHEN Xiang-mei | 2019 | Chinese Journal of Integrative Medicine2019,25,3: | 7 |
| 12 | Genistein protects hippocampal neurons against injury by regulating calcium/calmodulin dependent protein kinase Ⅳ protein levels in Alzheimer's disease model rats显示文摘Genistein has a neuroprotective effect in Alzheimer's disease, but its mechanism of action needs further clarification. Accumulating evidence suggests that excessive phosphorylation of tau protein causes production of neurofibrillary tangles, which is one of the main pathological characteristics of Alzheimer's disease, and tau protein can be phosphorylated by calcium/calmodulin dependent protein kinase IV(CAMK4). After 7 days of pre-administration of genistein(90 mg/kg), an Alzheimer's disease rat model was established using an intraperitoneal injection of D-galactose combined with an intracerebral injection of amyloid-β peptide(25–35). The rat was then continuously administered genistein(90 mg/kg) for 42 days. The Morris water maze test, western blotting and hematoxylin-eosin staining results showed that genistein significantly decreased the escape latency and increased the number of times crossing the platform, reduced p-tau, CALM, CAMKK1 and p-CAMK4 protein levels in the hippocampus, and alleviated hippocampal neuron damage. These findings indicate that genistein may play a neuroprotective role in Alzheimer's disease through regulating CAMK4 to modulate tau hyperphosphorylation. | Shu Ye Ting-ting Wang Biao Cai Yan Wang Jing Li Ji-xian Zhan Guo-ming Shen | 2017 | Neural Regeneration Research2017,12,9: | 7 |

| 14 | AntarcticaLC2000:The new Antarctic land cover database for the year 2000显示文摘Antarctica plays a key role in global energy balance and sea level change.It has been conventionally viewed as a whole ice body with high albedo in General Circulation Models or Regional Climate Models and the differences of land cover has usually been overlooked.Land cover in Antarctica is one of the most important drivers of changes in the Earth system.Detailed land cover information over the Antarctic region is necessary as spatial resolution improves in land process models.However,there is a lack of complete Antarctic land cover dataset derived from a consistent data source.To fill this data gap,we have produced a database named Antarctic Land Cover Database for the Year 2000(AntarcticaLC2000) using Landsat Enhanced Thematic Mapper Plus(ETM+) data acquired around 2000 and Moderate Resolution Imaging Spectrometer(MODIS) images acquired in the austral summer of 2003/2004 according to the criteria for the 1:100000-scale.Three land cover types were included in this map,separately,ice-free rocks,blue ice,and snow/firn.This classification legend was determined based on a review of the land cover systems in Antarctica(LCCSA) and an analysis of different land surface types and the potential of satellite data.Image classification was conducted through a combined usage of computer-aided and manual interpretation methods.A total of 4067 validation sample units were collected through visual interpretation in a stratified random sampling manner.An overall accuracy of 92.3%and the Kappa coefficient of 0.836 were achieved.Results show that the areas and percentages of ice-free rocks,blue ice,and snow/firn are 73268.81 km2(0.537%),225937.26 km2(1.656%),and 13345460.41 km2(97.807%),respectively.The comparisons with other different data proved a higher accuracy of our product and a more advantageous data quality.These indicate that AntarcticaLC2000,the new land cover dataset for Antarctica entirely derived from satellite data,is a reliable product for a broad spectrum of applications. | HUI FengMing KANG Jing LIU Yan CHENG Xiao GONG Peng WANG Fang LI Zhan YE YuFang GUO ZiQi | 2017 | Science China Earth Sciences2017,60,4: | 5 |
| 15 | 2022 Chinese national clinical practice guideline on Helicobacter pylori eradication treatment显示文摘Background:Helicobacter pylori(H.pylori)infection is an infectious disease with a prevalence rate of up to 50%worldwide.It can cause indigestion,gastritis,peptic ulcer,and gastric cancer.H.pylori eradication treatment can effectively control disease progression and reduce the risk of the above conditions.However,the escalating trend of antibiotic resistance presents a global challenge for H.pylori eradication.We aim to provide guidance on pharmacological treatment of H.pylori infection.Methods:This clinical practice guideline is developed following the World Health Organization’s recommended process,adopting Grading of Recommendations Assessment,Development and Evaluation in assessing evidence quality,and utilizing Evidence to Decision framework to formulate clinical recommendations,minimizing bias and increasing transparency of the clinical practice guideline development process.We used the Reporting Items for practice Guidelines in HealThcare(RIGHT)statement and The Appraisal of Guidelines for Research and Evaluation Ⅱ(AGREE Ⅱ)as reporting and conduct guides to ensure the guideline’s completeness and transparency.Results:Though decreasing in developed countries,the prevalence of H.pylori remains high in developing countries,causing a major public health burden.This clinical practice guideline contains 12 recommendations concerning pharmacological treatment for H.pylori eradication.Among them,it is worth highlighting that bismuth preparations are inexpensive,safe,and effective,consequently making bismuth quadruple therapy a preferred choice for initial and rescue treatment.In empirical treatment,high-dose dual therapy is equally effective compared with bismuth quadruple therapy.Conclusions:The 12 recommendations in this clinical practice guideline are formed with consideration for stakeholders’values and preferences,resource use,feasibility,and acceptability.Recommendations are generalizable to resource limited settings with similar antibiotic resistance pattern as China,and lower middle-income countries facing comparable sociological and technical challenges.Registration:Guidelines International Network(GIN)website,http://gffzz8d0dcdd112684267skf55vcfwfbok6cpp.ffgz.tsg.suse.edu.cn/node/69996. | Liya Zhou Hong Lu Zhiqiang Song Bin Lyu Ye Chen Jiyao Wang Jun Xia Zhan Zhao on behalf of Helicobacter Pylori Study Group of Chinese Society of Gastroenterology | 2022 | Chinese Medical Journal2022,135,24: | 5 |

| 17 | Dexmedetomidine mitigates isoflurane-induced neurodegeneration in fetal rats during the second trimester of pregnancy显示文摘Dexmedetomidine has significant neuroprotective effects. However, whether its protective effects can reduce neurotoxicity caused by isoflurane in fetal brain during the second trimester of pregnancy remains unclear. In this study, timed-pregnancy rats at gestational day 14 spontaneously inhaled 1.5% isoflurane for 4 hours, and were intraperitoneally injected with dexmedetomidine at dosages of 5, 10, 20, and 20 μg/kg 15 minutes before inhalation and after inhalation for 2 hours. Our results demonstrate that 4 hours after inhaling isoflurane, 20 μg/kg dexmedetomidine visibly mitigated isoflurane-induced neuronal apoptosis, reversed downregulation of brain-derived neurotrophic factor expression, and lessened decreased spatial learning and memory ability in adulthood in the fetal rats. Altogether, these findings indicate that dexmedetomidine can reduce neurodegeneration induced by isoflurane in fetal rats during the second trimester of pregnancy. Further, brain-derived neurotrophic factor participates in this process. | Zhi-yuan Su Qing Ye Xian-bao Liu Yu-zhong Chen Hong Zhan Shi-yuan Xu | 2017 | Neural Regeneration Research2017,12,8: | 5 |
| 18 | One-pot synthesis of the highly efficient bifunctional Ni-SAPO-11 catalyst显示文摘Hydro isomerization of linear alkanes to branched isomers is an important petrochemical process for production of gasoline with high octane number.Non-noble metal bifunctional catalysts used in this process always suffer from low metal dispersion and poor metal-acid synergy.Herein,a facile one-pot synthesis method was used to simultaneously regulate metal particle sizes and acidity of the Ni-SAPO-11 hydroisomerization catalyst.The physicochemical properties are investigated using XANES,EXAFS,TEM/STEM,FT-IR,XPS,UV-vis and NH_3-TPD.Apart from the highly dispersed nickel nanoparticles with an average diameter of 8 nm,the framework Ni~(2+)ions are generated via substituting framework Al~(3+)ions of the SAPO-11.The formed NiP-OH structures have lower deprotonation energy(DPE)than the SiAl-OH ones,contributing more and stronger acid sites to the Ni-SAPO-11 catalyst.The great metal-acid synergy including high metal to acid sites ratio(n_(Ni)/n_A)and close intimacy is obtained for the Ni-SAPO-11 catalyst.The Ni-SAPO-11 catalyst outperforms the counterpart prepared by the impregnation method and exhibits comparable activity and isomers selectivity to the Pt/SAPO-11 catalyst in the n-hexane hydroisomerization. | Yuchao Lyu Weilong Zhan Zhumo Yu Xinmei Liu Ye Yang Xiaoxing Wang Chunshan Song Zifeng Yan | 2021 | Journal of Materials Science & Technology2021,,17: | 4 |
| 19 | Deep Seismogenic Environment in the Southern Section of the Longmenshan Fault Zone on the Eastern Margin of the Tibetan Plateau and Lushan M_s 7.0 Earthquake显示文摘The 2,026 earthquake events registered by the Sichuan regional digital seismic network and mobile seismic array after the April 20 th,2013 Lushan earthquake and 28,188 pieces of data were selected to determine direct P waves arrival times. We applied the tomographic method to inverse the characteristics of the velocity structure for the three-dimensional(3D) P wave in the mid-upper crust of the seismic source region of the Lushan earthquake. The imaging results were combined with the apparent magnetization inversion and magnetotelluric(MT) sounding retest data to comprehensively study the causes of the deep seismogenic environment in the southern section of the Longmenshan fault zone and explore the formation of the Lushan earthquake. Research has shown that there are obvious differences in velocity structure and magnetic distribution between the southern and northern sections of the Longmenshan fault zone. The epicenter of the Lushan earthquake is located near the boundary of the high and low-velocity anomalies and favorable for a high-velocity section. Moreover,at the epicenter of the Lushan earthquake located on the magnetic dome boundary of Ya'an,the development of high velocity and magnetic solid medium favors the accumulation and release of strain energy. Lowvelocity anomalies are distributed underneath the are of seismogenic origin,The inversion results of the MT retest data after the April 20 th Lushan earthquake also indicate that there a high-conductor anomaly occurs under the area of seismogenic origin of the Lushan earthquake,Therefore,we speculated that the presence of a high-conductivity anomaly and low-velocity anomaly underneath the seismogenic body of the Lushan earthquake could be related to the existence of fluids. The role of fluids caused the weakening of the seismogenic layer inside the mid-upper crust and resulted in a seismogenic fault that was prone to rupture and played a triggering role in the Lushan earthquake. | LI Dahu DING Zhifeng ZHAN Yan WU Pingping YE Qingdong | 2015 | Acta Geologica Sinica(English Edition)2015,89,2: | 4 |
