1Undifferentiated (embryonal) sarcoma of liver in adult: A case report显示文摘We report a case of undifferentiated (embryonal)sarcoma of the liver (UESL), which showed cystic formation in a 20-year-old man with no prior history of any hepatitis or liver cirrhosis. He was admitted with abdominal pain and a palpable epigastric mass. The physical examination findings were unremarkable except for a tenderness mass and the results of routine laboratory studies were all within normal limits. Abdominal ultrasound and computed tomography (CT) both showed a cystic mass in the left hepatic lobe. Subsequently, the patient underwent a tumor excision and another two times of hepatectomy because of tumor recurrence.Immunohistochemical study results showed that the tumor cells were positive for vimentin, alpha-1-antichymotrypsin (AACT) and desmin staining, and negative for alphafetoprotein (AFP), and eosinophilic hyaline globules in the cytoplasm of some giant cells were strongly positive for periodic acid-Schiff (PAS) staining. The pathological diagnosis was UESL. The patient is still alive with no tumor recurrence for four months.Chao-LiuDai FengXu HongShu Yong-QingXu YongHuang 2005World Journal of Gastroenterology2005,11,6:6
2Enhanced photoresponse of Ti0_(2)/MoS_(2)heterostructure phototransistors by the coupling of interface charge transfer and photogating显示文摘Two-dimensional(2D)MoS_(2)with appealing physical properties is a promising candidate for next-generation electronic and optoelectronic devices,where the ultrathin MoS_(2)is usually laid on or gated by a dielectric oxide layer.The oxide/MoS_(2)interfaces widely existing in these devices have significant impacts on the carrier transport of the MoS_(2)channel by diverse interface interactions.Artificial design of the oxide/MoS_(2)interfaces would provide an effective way to break through the performance limit of the 2D devices but has yet been well explored.Here,we report a high-performance MoS_(2)-based phototransistor with an enhanced photoresponse by interfacing few-layer MoS_(2)with an ultrathin Ti0_(2)layer.The Ti0_(2)is deposited on MoS_(2)through the oxidation of an e-beam-evaporated ultrathin Ti layer.Upon a visible-light illumination,the fabricated Ti0_(2)/MoS_(2)phototransistor exhibits a responsivity of up to 2,199 A/W at a gate voltage of 60 V and a detectivity of up to 1.67×10^(13)Jones at a zero-gate voltage under a power density of 23.2μW/mm^(2).These values are 4.0 and 4.2 times those of the pure MoS_(2)phototransistor.The significantly enhanced photoresponse of Ti0_(2)/MoS_(2)device can be attributed to both interface charge transfer and photogating effects.Our results not only provide valuable insights into the interactions at Ti0_(2)/MoS_(2)interface,but also may inspire new approach to develop other novel optoelectronic devices based on 2D layered materials.Bingxu Liu Yinghui Sun Yonghuang Wu Kai Liu Huanyu Ye Fangtao Li Limeng Zhang Yong Jiang Rongming Wang 2021Nano Research2021,14,4:4

4蜜蜂褪黑素的测定方法显示文摘在脊椎动物中,褪黑素(5-甲氧基-N-乙酰色胺,MLT)是一种由松果体分泌的具有典型光周期信号作用的神经内分泌激素。近年在昆虫头部也发现了这种化学物质。该文简述了褪黑素常见测定方法,详细介绍了褪黑素的免疫测定方法RIA(radionimmunoassay),并使用该方法初步测定了中华蜜蜂ApisceranaFabricius工蜂头部褪黑素的含量,结果显示褪黑素含量与工蜂的社会分工相关。李秀 秦玉川 Zanchary YongHuang 宋敦伦 2005昆虫知识2005,42,1:3
5Precise Determination of the MgAlON/(AlN+MgAlON) Phase Bound- ries in the MgO-AlN-Al_2O_3 Ternary System at 1600℃ and 1700℃显示文摘The accurate phase boundary of MgAION/(AIN+MgAION) in MgO-AIN-Al2O3 ternary system, has not been determined precisely so far. In the present study, the lattice parameters of MgAION solid solution with various compositions were determined precisely with X-ray powder diffraction. According to the relationship between the lattice parameters of MgAION solid solution and the contents of AIN and MgO, the phase boundaries of MgAlON/(AIN+MgAlON) inMgO-AlN-Al2O3 ternary system at 1600℃ and 1700℃ were precisely determined.HouxingZHANG YanruoHONG YongHUANG JialinSUN 2005Journal of Materials Science & Technology2005,21,2:2
6Synthesis and Characterization of A Novel Cholesteric Liquid Crystalline Containing Carboxyl Group显示文摘A novel liquid crystal compound with a carboxyl group at one end, cholest-5-en-3-ol- (3β) hydrogen decanedioate (1) was successfuly prepared by the reaction of cholesterol with sebacoyl chloride. Its chemical structure and liquid crystalline properties were characterized by FTIR, CNMR, 1HNMR, POM and DSC. The compound with an active carboxyl group shows 13 themortropic liquid crystalline behaviour.JingMA YingNanXUAN YongHUANG 2005Chinese Chemical Letters2005,16,1:2
7Diagnosis of intestinal acariasis with avidin-biotin system enzyme-linked immunosorbent assay显示文摘AIM: To explore the value of avidin-biotin system enzyme-linked immunosorbent assay (ABC-ELISA) in diagnosis of intestinal acariasis.METHODS: Mite-specific IgG levels in serum of 48 patients with intestinal acariasis were measured with ABC-ELISA.The sensitivity of this method was compared with that of staphylococcal protein A enzyme-linked immunosorbent assay (SPA-ELISA).RESULTS: The positive rate of mite-specific IgG detected with ABC-ELISA and SPA-ELISA was 89.58% (43/48) and 56.25% (27/48), respectively. The positive rate with ABC-ELISA was statistically higher than that with SPA-ELISA (x^2= 13.50, P<0.01).CONCLUSION: ABC-ELISA is an effective method for the diagnosis of intestinal acariasis.Rong-BoZhang YongHuang Chao-PinLi Yu-BaoCui 2004World Journal of Gastroenterology2004,10,9:2
8Epidemiological Characteristics of An Outbreak of Severe Acute Respiratory Syndrome in Dongcheng District of Beijing From March to May 2003显示文摘Objective To describe epidemiologic features of an outbreak of severe acute respiratory syndrome (SARS) in Dongcheng District, Beijing occurred in a period between March and May 2003.Methods Data of SARS cases notified from Dongcheng District Center for Disease Control and Prevention(CDC)and supplemented by other channels were collected. Clinicians and officials of local hospitals were interviewed in groups and medical records of fatal cases of SARS were reviewed to verify the diagnosis. Stored serum specimens of the patients were detected for IgG antibody against SARS Co-V by enzyme-linked immunosorbent assay (ELISA). All the data were input into dataset files by Microsoft Excel-2000 software and analyzed with SPSS version 10.0 software. Results Outbreak of SARS in Dongcheng District started on March 14, 2003 with a peak in mid- and late April, and dropped in early May. A total of 572 reported cases were collected during this period in Dongcheng District, Beijing, and 99 of them were excluded from SARS, because of diagnosis of common cold, regular pneumonia, measles and rubella, etc. Actually, 473 SARS cases, which included390 (82.5%) probable cases and 83 (17.5%) suspect cases, were analyzed. About 90% of the probablecases were positive for IgG antibody. Attack rate of SARS in permanent residents of Dongcheng District was 28.3 per 100000. Forty-one of them died, with a case-fatality rate of 8.7%. Persons were all susceptible to infection of SARS Co-V, with the highest proportion at ages of 20-50 years, which accounted for 68.7% of the total cases. Average age of the patients at their onset was 40.7 years. Nogender difference in SARS cases was found. Number of SARS cases in health-care workers (HCWs)accounted for 18.0% and that in retired workers accounted for 15.4% of the total cases. Cases occurred in all 10 sub-districts of Dongcheng, with the highest in Beixinqiao and Andingmen Sub-districts. Totally, 230 of the 572 notified cases (40.2%) were hospitalized at local hospitals under the jurisdiction of Dongcheng District. Eighteen of 85 cases of SARS occurred in HCWs of local hospitals, accounting for 4.5% of the total number of HCWs working at wards caring for SARS patients or fever clinics. There were 34.7% of SARS cases without any histories of contact before theonset of the disease. Familial aggregation phenomena were observed in 41.8% of the cases and 18.1%of households. And 7.4% ( attack rate ) of those exposed to SARS cases suffered from the illness during the periods of quarantine. Conclusions SARS appeared to be infectious in origin and caused outbreak in Dongcheng District, Beijing introduced by an imported case traveling from Hong Kong in a period between March and May 2003. People are all susceptible to infection of SARS Co-V, which mainly threatens the young adults and the middle-aged, as well as HCWs and the retired workers. The main mode of transmission is direct exposure to SARS patients in a near distance at hospitals orfamilies via droplets spread. Prevention and control of SARS should be focused on early isolation of patients and quarantine for close contacts. Current available measures to prevent and control SARS are proved to be effective.WAN—NIANLIANG‘ YONGHUANG WAN—XINZHOU LEIQIAO JIAN—HuIHUANG ZHENG—LAIWU 2003Biomedical and Environmental Sciences2003,16,4:2
