| 2 | Pretreated quercetin protects gerbil hippocampal CA1 pyramidal neurons from transient cerebral ischemic injury by increasing the expression of antioxidant enzymes显示文摘Quercetin(QE; 3,5,7,3′,4′-pentahydroxyflavone), a well-known flavonoid, has been shown to prevent against neurodegenerative disorders and ischemic insults. However, few studies are reported regarding the neuroprotective mechanisms of QE after ischemic insults. Therefore, in this study, we investigated the effects of QE on ischemic injury and the expression of antioxidant enzymes in the hippocampal CA1 region of gerbils subjected to 5 minutes of transient cerebral ischemia. QE was pre-treated once daily for 15 days before ischemia. Pretreatment with QE protected hippocampal CA1 pyramidal neurons from ischemic injury, which was confirmed by neuronal nuclear antigen immunohistochemistry and Fluoro-Jade B histofluorescence staining. In addition, pretreatment with QE significantly increased the expression levels of endogenous antioxidant enzymes Cu/Zn superoxide dismutase, Mn superoxide dismutase, catalase and glutathione peroxidase in the hippocampal CA1 pyramidal neurons of animals with ischemic injury. These findings demonstrate that pretreated QE displayed strong neuroprotective effects against transient cerebral ischemia by increasing the expression of antioxidant enzymes. | Bai Hui Chen Joon Ha Park Ji Hyeon Ahn Jeong Hwi Cho In Hye Kim Jae Chul Lee Moo-Ho Won Choong-Hyun Lee In Koo Hwang Jong-Dai Kim Il Jun Kang Jun Hwi Cho Bich Na Shin Yang Hee Kim Yun Lyul Lee Seung Min Park | 2017 | Neural Regeneration Research2017，12，2： | 9 |

| 5 | Effect of hyperthermia on calbindin-D 28k immunoreactivity in the hippocampal formation following transient global cerebral ischemia in gerbils显示文摘Calbindin D-28K(CB), a Ca2+-binding protein, maintains Ca2+ homeostasis and protects neurons against various insults. Hyperthermia can exacerbate brain damage produced by ischemic insults. However, little is reported about the role of CB in the brain under hyperthermic condition during ischemic insults. We investigated the effects of transient global cerebral ischemia on CB immunoreactivity as well as neuronal damage in the hippocampal formation under hyperthermic condition using immunohistochemistry for neuronal nuclei(Neu N) and CB, and Fluoro-Jade B histofluorescence staining in gerbils. Hyperthermia(39.5 ± 0.2°C) was induced for 30 minutes before and during transient ischemia. Hyperthermic ischemia resulted in neuronal damage/death in the pyramidal layer of CA1–3 area and in the polymorphic layer of the dentate gyrus at 1, 2, 5 days after ischemia. In addition, hyperthermic ischemia significantly decreaced CB immunoreactivity in damaged or dying neurons at 1, 2, 5 days after ischemia. In brief, hyperthermic condition produced more extensive and severer neuronal damage/death, and reduced CB immunoreactivity in the hippocampus following transient global cerebral ischemia. Present findings indicate that the degree of reduced CB immunoreactivity might be related with various neuronal damage/death overtime and corresponding areas after ischemic insults. | Jae-Chul Lee Jeong-Hwi Cho Tae-Kyeong Lee In Hye Kim Moo-Ho Won Geum-Sil Cho Bich-Na Shin In Koo Hwang Joon Ha Park Ji Hyeon Ahn Il Jun Kang Young Joo Lee Yang Hee Kim | 2017 | Neural Regeneration Research2017，12，9： | 2 |
| 6 | Direct Synthesis of Molybdenum Phosphide Nanorods on Silicon Using Graphene at the Heterointerface for Efficient Photoelectrochemical Water Reduction显示文摘Transition metal phosphides(TMPs)and transition metal dichalcogenides(TMDs)have been widely investigated as photoelectrochemical(PEC)catalysts for hydrogen evolution reaction(HER).Using high-temperature processes to get crystallized compounds with large-area uniformity,it is still challenging to directly synthesize these catalysts on silicon photocathodes due to chemical incompatibility at the heterointerface.Here,a graphene interlayer is applied between p-Si and MoP nanorods to enable fully engineered interfaces without forming a metallic secondary compound that absorbs a parasitic light and provides an inefficient electron path for hydrogen evolution.Furthermore,the graphene facilitates the photogenerated electrons to rapidly transfer by creating Mo-O-C covalent bondings and energetically favorable band bending.With a bridging role of graphene,numerous active sites and anti-reflectance of MoP nanorods lead to significantly improved PEC-HER performance with a high photocurrent density of 21.8 mA cm−2 at 0 V versus RHE and high stability.Besides,low dependence on pH and temperature is observed with MoP nanorods incorporated photocathodes,which is desirable for practical use as a part of PEC cells.These results indicate that the direct synthesis of TMPs and TMDs enabled by graphene interlayer is a new promising way to fabricate Si-based photocathodes with high-quality interfaces and superior HER performance. | Sang Eon Jun Seokhoon Choi Shinyoung Choi Tae Hyung Lee Changyeon Kim Jin Wook Yang Woon‑Oh Choe In‑Hyuk Im Cheol‑Joo Kim Ho Won Jang | 2021 | Nano-Micro Letters2021，13，5： | 1 |
| 7 | Pembrolizumab-induced psoriatic arthritis treated with disease-modifying anti-rheumatic drugs in a patient with gastric cancer:A case report显示文摘BACKGROUND Immune checkpoint inhibitor(ICI)-induced rheumatic immune-related adverse events(ir AEs)have been infrequently reported,and the treatment of severe or refractory arthritis as ir AEs has not been established yet.CASE SUMMARY The patient was a 67-year-old man with a history of well-controlled foot psoriasis who presented with polyarthralgia.He had received pembrolizumab for metastatic gastric adenocarcinoma 2 mo previously.Physical examination revealed erythematous swelling in the distal interphalangeal joints,left shoulder,and both knees.He had plaque psoriasis with psoriatic nail dystrophy and dactylitis in the distal joints of the fingers and toes.Inflammatory markers including C-reactive protein and erythrocyte sedimentation rate were elevated but rheumatoid factor and anticyclic citrullinated peptide antibody were negative.The patient was diagnosed with psoriatic arthritis(PsA)and started on methylprednisolone 1 mg/kg/day after pembrolizumab discontinuation.However,despite 1 wk of methylprednisolone treatment,PsA worsened;hence,leflunomide and methotrexate were started.After 4 wk of steroid treatment,PsA worsened and improved repeatedly with steroid tapering.Therefore,the therapy was intensified to include etanercept,a tumor necrosis factor inhibitor,which ultimately resulted in adequate PsA control.CONCLUSION This is the first report of ICI-induced PsA in a gastric cancer patient.Some rheumatic ir AEs with refractory severe arthritis may require disease-modifying anti-rheumatic drugs and long-term management. | Sehan Kim Jong Hee Sun Hongsik Kim Hee Kyung Kim Yaewon Yang Jun Su Lee In Ah Choi Hye Sook Han | 2023 | World Journal of Clinical Cases2023，11，1： | 1 |

| 9 | Different oncological features of colorectal cancer codon-specific KRAS mutations:Not codon 13 but codon 12 have prognostic value显示文摘BACKGROUND Approximately 40%of colorectal cancer(CRC)cases are linked to Kirsten rat sarcoma viral oncogene homolog(KRAS)mutations.KRAS mutations are associated with poor CRC prognosis,especially KRAS codon 12 mutation,which is associated with metastasis and poorer survival.However,the clinicopathological characteristics and prognosis of KRAS codon 13 mutation in CRC remain unclear.AIM To evaluate the clinicopathological characteristics and prognostic value of codonspecific KRAS mutations,especially in codon 13.METHODS This retrospective,single-center,observational cohort study included patients who underwent surgery for stage I-III CRC between January 2009 and December 2019.Patients with KRAS mutation status confirmed by molecular pathology reports were included.The relationships between clinicopathological characteristics and individual codon-specific KRAS mutations were analyzed.Survival data were analyzed to identify codon-specific KRAS mutations as recurrence-related factors using the Cox proportional hazards regression model.RESULTS Among the 2203 patients,the incidence of KRAS codons 12,13,and 61 mutations was 27.7%,9.1%,and 1.3%,respectively.Both KARS codons 12 and 13 mutations showed a tendency to be associated with clinical characteristics,but only codon 12 was associated with pathological features,such as stage of primary tumor(T stage),lymph node involvement(N stage),vascular invasion,perineural invasion,tumor size,and microsatellite instability.KRAS codon 13 mutation showed no associations(77.2%vs 85.3%,P=0.159),whereas codon 12 was associated with a lower 5-year recurrence-free survival rate(78.9%vs 75.5%,P=0.025).In multivariable analysis,along with T and N stages and vascular and perineural invasion,only codon 12(hazard ratio:1.399;95%confidence interval:1.034-1.894;P=0.030)among KRAS mutations was an independent risk factor for recurrence.CONCLUSION This study provides evidence that KRAS codon 13 mutation is less likely to serve as a prognostic biomarker than codon 12 mutation for CRC in a large-scale cohort. | Hong-Min Ahn Duck-Woo Kim Tae Gyun Lee Hye-Rim Shin In Jun Yang Jeehye Lee Jung Wook Suh Heung-Kwon Oh Sung-Bum Kang | 2023 | World Journal of Gastroenterology2023，29，32： | 0 |
| 10 | Practice of reperfusion in patients with ST-segment elevation myocardial infarction in China:findings from the Improving Care for Cardiovascular Disease in China–Acute Coronary Syndrome project显示文摘Background:Reperfusion therapy is fundamental for ST-segment elevation myocardial infarction(STEMI).However,the details of contemporary practice and factors associated with reperfusion therapy in China are largely unknown.Therefore,this study aimed to explore reperfusion practice and its associated factors among hospitalized patients with STEMI in China.Methods:Patients with STEMI who were admitted to 159 tertiary hospitals from 30 provinces in China were included in the Improving Care for Cardiovascular Disease in China–Acute Coronary Syndrome project from November 2014 to December 2019.The associations of the characteristics of patients and hospitals with reperfusion were examined using hierarchical logistic regression.The associations between therapies and in-hospital major adverse cardiovascular events were examined with a mixed effects Cox regression model.Results:Among the 59,447 patients,37,485(63.1%)underwent reperfusion,including 4556(7.7%)receiving fibrinolysis and 32,929(55.4%)receiving primary percutaneous coronary intervention(PCI).The reperfusion rate varied across geographical regions(48.0%–73.5%).The overall rate increased from 60.0%to 69.7%from 2014 to 2019,mainly due to an increase in primary PCI within 12 h of symptom onset.Timely PCI,but not fibrinolysis alone,was associated with a decreased risk of inhospital major adverse cardiovascular events compared with no reperfusion,with an adjusted hazard ratio(95%confidence interval)of 0.64(0.54,0.76)for primary PCI at<12 h,0.53(0.37,0.74)for primary PCI at 12 to 24 h,0.46(0.25,0.82)for the pharmaco-invasive strategy,and 0.79(0.54,1.15)for fibrinolysis alone.Conclusions:Nationwide quality improvement initiatives should be strengthened to increase the reperfusion rate and reduce inequality in China.Trial registration:www.ClinicalTrials.gov,NCT02306616。 | Yiqian Yang Yongchen Hao Jun Liu Na Yang Danqing Hu Zhaoqing Sun Dong Zhao Jing Liu on behalf of the Improving Care for Cardiovascular Disease in China-Acute Coronary Syndrome(CCC-ACS)Investigators | 2022 | Chinese Medical Journal2022，135，23： | 0 |
| 11 | Diagnosis Analysis of One Cold Airflow Snowfall in Shandong Peninsula显示文摘[Objective]One cold airflow snowfall in Shandong Peninsula was analyzed.[Method] Using conventional weather observation data,the NCEP /NCAR 1°×1° grid point by 6 h in data analysis,the synoptic weather dynamics principle and diagnosis analysis method,the cold airflow snowfall in Shandong Peninsula on December 4,2008 to 6 th was analyzed and summarized.[Result]The results showed that the cold deep groove of large scale circulation form caused the cold airflow snowfall in Shandong Peninsula.While the 850 hPa mistral wind strengthened,cold airflow snow in Shandong Peninsula will be strengthened.During the eruption of snowstorm,the relative humidity from 925 to 750 hPa was larger than 90%.The area formed by 90% relative humidity line corresponded with the period of heavy snowfall.The changes of relative humidity line reflected the changes of warm and wet air transmitting to the higher place.The more warm and wet air being sent to the upper air,the more conductive to the formation of cold airflow snowfall in Shandong Peninsula.The cold airflow snowfall had distinct temporal and spatial distribution characteristics and corresponded with the vertical increasing movement zone.[Conclusion]The study provided reference for the preciseness of short term and incoming report of cold airflow snowfall in Shandong Peninsula. | LI Bing-wen 1,LI Jun 2,WANG Qing-hua 1,YANG Kun 1 1.Linyi Meteorological Bureau in Shandong Province,Linyi 276004,China 2.Cangshan Meteorological Bureau in Shandong Province,Cangshan 277700,China | 2011 | Meteorological and Environmental Research2011，2，11： | 0 |
