1Biochemical characteristics of neonatal cholestasis induced by citrin deficiency显示文摘AIM:To explore differences in biochemical indices between neonatal intrahepatic cholestasis caused by citrin deficiency (NICCD) and that with other etiologies. METHODS:Patients under 6 mo of age who were referred for investigation of conjugated hyperbiliru-binaemia from June 2003 to December 2010 were eligible for this study. After excluding diseases affecting the extrahepatic biliary system, all patients were screened for the two most common SLC25A13 mutations; the coding exons of the entire SLC25A13 gene was sequenced and Western blotting of citrin protein performed in selected cases. Patients in whom homo-zygous or compound heterozygous SLC25A13 mutation and/or absence of normal citrin protein was detected were defined as having NICCD. Cases in which no specific etiological factor could be ascertained after a com-prehensive conjugated hyperbilirubinaemia work-up were defined as idiopathic neonatal cholestasis (INC). Thirty-two NICCD patients, 250 INC patients, and 39 infants with cholangiography-confirmed biliary atresia (BA) were enrolled. Laboratory values at their first visit were abstracted from medical files and compared. RESULTS:Compared with BA and INC patients, the NICCD patients had significantly higher levels of total bile acid (TBA) [all measures are expressed as median (inter-quartile range):178.0 (111.2-236.4) μmol/L in NICCD vs 112.0 (84.9-153.9) μmol/L in BA and 103.0 (70.9-135.3) μmol/L in INC, P = 0.0001]. The NICCD patients had significantly lower direct bilirubin [D-Bil 59.6 (43.1-90.9) μmol/L in NICCD vs 134.0 (115.9-151.2) μmol/L in BA and 87.3 (63.0-123.6) μmol/L in INC, P = 0.0001]; alanine aminotransferase [ALT 34.0 (23.0-55.0) U/L in NICCD vs 108.0 (62.0-199.0) U/L in BA and 84.5 (46.0-166.0) U/L in INC, P = 0.0001]; aspartate aminotransferase [AST 74.0 (53.5-150.0) U/L in NICCD vs 153.0 (115.0-239.0) U/L in BA and 130.5 (81.0-223.0) U/L in INC, P = 0.0006]; albumin [34.9 (30.7-38.2) g/L in NICCD vs 38.4 (36.3-42.2) g/L in BA and 39.9 (37.0-42.3) g/L in INC, P = 0.0001]; glucose [3.2 (2.0-4.4) mmol/L in NICCD vs 4.1 (3.4-5.1) mmol/L in BA and 4.0 (3.4-4.6) mmol/L in INC, P = 0.0014] and total cholesterol [TCH 3.33 (2.97-4.00) mmol/L in N ICCD vs 4.57 (3.81-5.26) mmol/L in BA and 4.00 (3.24-4.74) mmol/L in INC, P = 0.0155] levels. The D-Bil to total bilirubin (T-Bil) ratio was significantly lower in NICCD patients [all measures are expressed as median (inter-quartile range):0.54 (0.40-0.74)] than that in BA patients [0.77 (0.72-0.81), P = 0.001] and that in INC patients [0.74 (0.59-0.80), P = 0.0045]. A much higher AST/ALT ratio was found in NICCD patients [2.46 (1.95-3.63)] compared to BA patients [1.38 (0.94-1.97), P = 0.0001] and INC patients [1.48 (1.10-2.26), P = 0.0001]. NICCD patients had significantly higher TBA/D-Bil ratio [3.36 (1.98-4.43) vs 0.85 (0.72-1.09) in BA patients and 1.04 (0.92-1.14) in INC patients, P = 0.0001], and TBA/TCH ratio [60.7 (32.4-70.9) vs 24.7 (19.8-30.2) in BA patients and 24.2 (21.4-26.9) in INC patients, P = 0.0001] compared to the BA and INC groups. CONCLUSION:NICCD has significantly different bio- chemical indices from BA or INC. TBA excretion in NICCD appeared to be more severely disturbed than that of bilirubin and cholesterol.Jian-She Wang Xiao-Hong Wang Ying-Jie Zheng Hai-Yan Fu Rui Chen Yi Lu Ling-Juan Fang Takeyori Saheki Keiko Kobayashi 2012World Journal of Gastroenterology2012,18,39:35
2Analysis of Factors Associated with Death in Maintenance Hemodialysis Patients: A Multicenter Study in China显示文摘Kang-Kang Song De-Long Zhao Yuan-Da Wang Yong Wang Xue-Feng Sun Li-Ning Miao Zhao-Hui Ni Hong-Li Lin Fu-You Liu Ying Li Ya-Ni He Nian-Song Wang Cai-Li Wang Ai-Hua Zhang Meng-Hua Chen Xiao-Ping Yang Yue-Yi Deng Feng-Min Shao Shu-Xia Fu Jing-Ai Fang Guang-Yan Cai Xiang-Mei Chen 2017Chinese Medical Journal2017,,8:39
3Different treatment strategies and molecular features between right-sided and left-sided colon cancers显示文摘The colon is derived from the embryological midgut and hindgut separately,with the right colon and left colon having different features with regards to both anatomical and physiological characteristics.Cancers located in the right and left colon are referred to as right colon cancer(RCC) and left colon cancer(LCC),respectively,based on their apparent anatomical positions.Increasing evidence supports the notion that not only are there differences in treatment strategies when dealing with RCC and LCC,but molecular features also vary between them,not to mention the distinguishing clinical manifestations.Disease-free survival after radical surgery of both RCC and LCC are similar.In the treatment of RCC,the benefit gained from adjuvant FOLFIRI chemotherapy is superior,or at least similar,to LCC,but inferior to LCC if FOLFOX regimen is applied.On the other hand,metastatic LCC exhibits longer survival than that of RCC in a palliative chemotherapy setting.For KRAS wild-type cancers,LCC benefits more from cetuximab treatment than RCC.Moreover,advanced LCC shows a higher sensitivity to bevacizumab treatment in comparison with advanced RCC.Significant varieties exist at the molecular level between RCC and LCC,which may serve as the cause of all apparent differences.With respect to carcinogenesis mechanisms,RCC is associated with known gene types,such as MMR,KRAS,BRAF,and mi RNA-31,while LCC is associated with CIN,p53,NRAS,mi RNA-146 a,mi RNA-147 b,and mi RNA-1288.Regarding protein expression,RCC is related to GNAS,NQO1,telomerase activity,P-PDH,and annexin A10,while LCC is related to Topo I,TS,and EGFR.In addition,separated pathways dominate progressionto relapse in RCC and LCC.Therefore,RCC and LCC should be regarded as two heterogeneous entities,with this heterogeneity being used to stratify patients in order for them to have the optimal,current,and novel therapeutic strategies in clinical practice.Additional research is needed to uncover further differences between RCC and LCC.Hong Shen Jiao Yang Qing Huang Meng-Jie Jiang Yi-Nuo Tan Jian-Fei Fu Li-Zhen Zhu Xue-Feng Fang Ying Yuan 2015World Journal of Gastroenterology2015,21,21:33
4Effect of lifestyle intervention on non-alcoholic fatty liver disease in Chinese obese children显示文摘AIM: To investigate the effect of lifestyle intervention on non-alcoholic fatty liver disease (NAFLD) in Chinese obese children. METHODS: Seventy-six obese children aged from 10 to 17 years with NAFLD were enrolled for a one-month intervention and divided randomly into three groups. Group1, consisting of 38 obese children, was an untreated control group without any intervention. Group 2, consisting of 19 obese children in summer camp, was strictly controlled only by life style intervention. Group 3, consisting of 19 obese children, received oral vitamin E therapy at a dose of 100 mg/d. The height, weight, fasting blood glucose (FBG), fasting serum insulin (FINS), plasma alanine aminotransferase (ALT), aspartate aminotransferase (AST), triglyceride (TG), total cholesterol (TCHO) and homeostasis model assent- insulin resistance (HOMA-IR) were measured at baseline and after one month. All patients were underwent to an ultrasonographic study of the liver performed by one operator who was blinded to the groups. RESULTS: The monitor indices of BMI, ALT, AST, TG, TCHO and HOMA-IR were successfully improved except in group 1. BMI and ALT in group 2 were reduced more significantly than in group 3 (2.44 ± 0.82 vs 1.45 ± 0.80, P = 0.001; 88.58 ± 39.99 vs 63.69 ± 27.05, P = 0.040, respectively).CONCLUSION: Both a short-term lifestyle intervention and vitamin E therapy have an effect on NAFLD in obese children. Compared with vitamin E, lifestyle intervention is more effective. Therefore, lifestyle intervention should represent the first step in the management of children with NAFLD.Chun-Lin Wang Li Liang Jun-Fen Fu Chao-Chun Zou Fang Hong Jin-Zheng Xue Jin-Rui Lu Xiang-Min Wu 2008World Journal of Gastroenterology2008,14,10:28
5Overexpression of brain-derived neurotrophic factor in the hippocampus protects against post-stroke depression显示文摘Post-stroke depression is associated with reduced expression of brain-derived neurotrophic factor(BDNF). In this study, we evaluated whether BDNF overexpression affects depression-like behavior in a rat model of post-stroke depression. The middle cerebral artery was occluded to produce a model of focal cerebral ischemia. These rats were then subjected to isolation-housing combined with chronic unpredictable mild stress to generate a model of post-stroke depression. A BDNF gene lentiviral vector was injected into the hippocampus. At 7 days after injection, western blot assay and real-time quantitative PCR revealed that BDNF expression in the hippocampus was increased in depressive rats injected with BDNF lentivirus compared with depressive rats injected with control vector. Furthermore, sucrose solution consumption was higher, and horizontal and vertical movement scores were increased in the open field test in these rats as well. These findings suggest that BDNF overexpression in the hippocampus of post-stroke depressive rats alleviates depression-like behaviors.Hao-hao Chen Ning Zhang Wei-yun Li Ma-rong Fang Hui Zhang Yuan-shu Fang Ming-xing Ding Xiao-yan Fu 2015Neural Regeneration Research2015,10,9:28
6Charlson comorbidity index helps predict the risk of mortality for patients with type 2 diabetic nephropathy显示文摘研究目的:探讨Charlson合并症指数(CCI)对2型糖尿病肾病死亡率的预测作用。研究方法:建立2型糖尿病肾病研究队列,根据CCI评分将患者合并症的严重程度分为三度:轻度(CCI1–2分)、中度(CCI 3–4分)、重度(CCI≥5分)。将影响死亡率的因素及按CCI分层后的组间差异指标进行Logistic回归分析及方差分析(ANOVA)。Kaplan-Meier生存曲线分析CCI指数对生存时间及死亡率的影响。重要结论:533例2型糖尿病肾病患者纳入研究。所有患者的CCI评分均大于1,44.7%(238/533)的患者死亡。患者的死亡率随CCI评分增加而增加,CCI 1–2分患者的死亡率为21.0%(50/238),CCI 3–4分患者的死亡率为56.7%(135/238),CCI≥5分患者的死亡率为22.3%(53/238)。Logistic回归分析显示CCI评分、血红蛋白和血浆白蛋白水平是患者死亡率的预测因子(P<0.05)。方差分析结果显示,与CCI评分相对较低的患者相比,CCI评分越高的患者其血红蛋白水平较低,而血清肌酐较高,死亡率也更高。Kaplan-Meier生存曲线显示CCI评分越高的患者生存时间越短。CCI评分是一种简单易行且实用的评估疾病合并症的方法,可用于预测2型糖尿病肾病患者的死亡率。关注2型糖尿病肾病患者的合并症将有利于早期、有效治疗及改善预后。You-qun HUANG Rong GOU Yong-shu DIAO Qing-hua YIN Wen-xing FAN Ya-ping LIANG Yi CHEN Min WU Li ZANG Ling LI Jing ZANG Lu CHENG Ping FU Fang LIU 2014Journal of Zhejiang University-Science B(Biomedicine & Biotechnology)2014,15,1:23

8Dendritic Cells Transduced with SOCS1 Gene Exhibit Regulatory DC Properties and Prolong Allograft Survival显示文摘SOCS1 is a key regulator of cytokine signaling and is important for maintaining balance in the immune system. It is thought to participate in negative feedback loops in cytokine signaling and may be an important signal for the regulation of dendritic cell (DC) maturation. However, it remains unclear whether DCs transduced with SOCS1 exhibit characteristics of regulatory DCs and induce allogeneic T-cell hyporesponsiveness. In this study, we constructed adenoviral vector coding SOCS1 (Ad-SOCS1) that can efficiently increase SOCS1 gene expression in bone marrow-derived dendritic cells. DCs transduced with Ad-SOCS1 (DC-SOCS1) expressed low levels of costimulatory and MHC molecules, were resistant to maturation and activation stimulation, induced allogeneic T-cell hyporesponsiveness, and promoted the generation of regulatory-like T cells in vitro. DC-SOCS1 pretreatment significantly prolonged the survival of allografts and led to a substantial increase in the generation of regulatory T cells. Our data suggest that SOCS1 inhibits DC maturation and induces regulatory DC generation, therefore possessing therapeutic potential to prevent rejection in organ transplantation.Hong Fu Shaohua Song Fang Liu Zhijia Ni Xiaoyun Shen Liang Xiao Guoshan Ding Quanxing Wang 2009Cellular & Molecular Immunology2009,6,2:20
9Applications of HPLC/MS in the analysis of traditional Chinese medicines显示文摘In China,traditional Chinese medicines(TCMs)have been used in clinical applications for thousands of years.The successful hyphenation of high-performance liquid chromatography(HPLC)and mass spectrometry(MS)has been applied widely in TCMs and biological samples analysis.Undoubtedly,HPLC/MS technique has facilitated the understanding of the treatment mechanism of TCMs.We reviewed more than 350 published papers within the last 5 years on HPLC/MS in the analysis of TCMs.The present review focused on the applications of HPLC/MS in the component analysis,metabolites analysis,and pharmacokinetics of TCMs etc.50% of the literature is related to the component analysis of TCMs,which show that this field is the most popular type of research.In the metabolites analysis,HPLC coupled with electrospray ionization quadrupole time-of-flight tandem mass spectrometry has been demonstrated to be the powerful tool for the characterization of structural features and fragmentation behavior patterns.This paper presented a brief overview of the applications of HPLC/MS in the analysis of TCMs.HPLC/MS in the fingerprint analysis is reviewed elsewhere.Miao Li Xiao- Fang Hou Jie Zhang Si-Cen Wang Qiang Fu Lang- Chong He 2011Journal of Pharmaceutical Analysis2011,1,2:17

17Analysis for retrieval and validation results of FY-3 Total Ozone Unit (TOU)显示文摘Retrieval experiment was made for global total column ozone using the first year measurements of Total Ozone Unit (TOU) on board the second generation polar orbiting meteorological satellite of China, FY-3/A. The retrieval results were analyzed and validated by comparison with AURA/OMI, Meteop/GOME-2 global ozone products and ground-based ozone measurement data. The qualititative comparisons over the globe especially over Antarctica and the Tibetan Plateau show that the spatial and temporal distribution characteristics are consistent with OMI and GOME-2 products. The quantitative comparisons with ground-based measurements and AURA/OMI ozone product were made over 74 stations, the TOU total ozone retrieval has a 3% rms relative error compared with AURA/OMI ozone product and 4.2% rms relative error with ground-based measurements. The maximum difference between satellite retrieval and ground-based measurements was found in the Antarctica ozone hole. The TOU global ozone product is operational and distributed to all users.WANG WeiHe ZHANG XingYing AN XingQin ZHANG Yan HUANG FuXiang WANG YongMei WANG YingJian ZHANG ZhongMou LU JianGong FU LiPing JIANG Fang LIU GuoYang 2010Chinese Science Bulletin2010,55,26:12
18Effect of high glucose levels on the calcification of vascular smooth muscle cells by inducing osteoblastic differentiation and intracellular calcium deposition via BMP-2/Cbfα-1 pathway显示文摘In this paper,we investigate the effect and the possible mechanism of high glucose levels on the calcification of human aortic smooth muscle cells (HASMCs).HASMCs were divided into four groups: normal glucose group (NG),osmolality control group (OC),high glucose group (HG,HASMCs culture medium containing 30 mmol/L glucose),and high glucose plus recombinant human Noggin protein (bone morphogenetic protein-2 (BMP-2) antagonist) group (HN).The mRNA levels and the protein expressions of BMP-2 and core binding factor alpha-1 (Cbfα-1) were measured by real-time quantitative polymerase chain reaction (PCR) and Western blot.After induced by 10 mmol/L β-glycerol phosphoric acid,cells were harvested for assessments of alkaline phosphatase (ALP) activities at Days 1,2,and 3,and intracellular calcium contents at Days 7 and 14,respectively.High glucose levels increased the mRNA levels and the protein expressions of BMP-2 and Cbfα-1 (P<0.05).The expression of Cbfα-1 was partially blocked by Noggin protein (P<0.05),while BMP-2 was not (P>0.05).After being induced by β-glycerol phosphoric acid,high glucose levels increased the ALP activity [(48.63±1.03) vs.(41.42±2.28) U/mg protein,Day 3;P<0.05] and the intracellular calcium content [(2.76±0.09) vs.(1.75±0.07) μmol/mg protein,Day 14;P<0.05] in a time-dependent manner when compared with the NG group,while the ALP activity could not be blocked by Noggin protein [(48.63±1.03) vs.(47.37±0.97) U/mg protein,Day 3;P>0.05].These results show that high glucose levels can evoke the calcification of HASMCs by inducing osteoblastic trans-differentiation and intracellular calcium deposition via the BMP-2/Cbfα-1 pathway,which can be partially blocked by Noggin protein.Fang LIU Hui ZHONG Jing-yuan LIANG Ping FU Zhi-juan LUO Li ZHOU Rong GOU Jun HUANG 2010Journal of Zhejiang University-Science B(Biomedicine & Biotechnology)2010,11,12:12
19Identification of a Newly Isolated Getah Virus in the China-Laos Border,China显示文摘In this study, we isolated a virus strain(YN12031) from specimens of Armigeres subalbatus collected in the China-Laos border. BHK-21 cells infected with YN12031 exhibited an evident cytopathic effect(CPE) 32 h post-infection. The virus particles were spherical, 70 nm in diameter, and enveloped; they also featured surface fibers. Molecular genetic analysis revealed that YN12031 was closely related to alpha viruses such as Chikungunya virus and Sindbis virus, and located in the same clade as MM2021, the prototype of Getahvirus(GETV) isolated in Malaysia in 1955. Phylogenetic analysis of the E2 and capsid genes further revealed that YN12031 was located in the same clade as the Russian isolate LEIV/16275/Mag. Analysis of the homology of nucleotides and amino acids in the coding area and E2 gene demonstrated that the YN12031 isolated from the China-Laos border(tropical region) was related closest to the LEIV/16275/Mag isolate obtained in Russia(North frigid zone area) among other isolates studied. These results suggest that GETV can adapt to different geographical environments to propagate and evolve. Thus, strengthening the detection and monitoring of GETV and its related diseases is very crucial.LI Yuan Yuan FU Shi Hong GUO Xiao Fang LEI Wen Wen LI Xiao Long SONG Jing Dong CAO Lei GAO Xiao Yan LYU Zhi HE Ying WANG Huan Yu REN Xiao Jie ZHOU Hong Ning WANG Gui Qin LIANG Guo Dong 2017Biomedical and Environmental Sciences2017,30,3:12
20Effect of annealing treatment on the structural, optical, and electrical properties of Al-doped ZnO thin films显示文摘Highly conductive and transparent Al-doped ZnO (AZO) thin films were prepared from a zinc target containing Al (1.5 wt.%) by direct current (DC) and radio frequency (RF) reactive magnetron sputtering. The structural, optical, and electrical properties of AZO films as-deposited and submitted to annealing treatment (at 300 and 400°C, respectively) were characterized using various techniques. The experimental results show that the properties of AZO thin films can be further improved by annealing treatment. The crystallinity of ZnO films improves after annealing treatment. The transmittances of the AZO thin films prepared by DC and RF reactive magnetron sputtering are up to 80% and 85% in the visible region, re- spectively. The electrical resistivity of AZO thin films prepared by DC reactive magnetron sputtering can be as low as 8.06 × 10?4 ??cm after annealing treatment. It was also found that AZO thin films prepared by RF reactive magnetron sput- tering have better structural and optical properties than that prepared by DC reactive magnetron sputtering.LI Li FANG Liang CHEN Ximing LIU Gaobin LIU Jun YANG Fengfan FU Guangzong KONG Chunyang 2007Rare Metals2007,26,3:11
