| 1 | Characteristics of Obesity and Its Related Disorders in China显示文摘Obesity is a medical condition with excess body fat accumulation to the extent which leads to serious health consequences.Abdominal obesity,also known as central obesity,refers to the presence of excess fat in the abdominal area.Obesity,especially abdominal obesity,contributes to many metabolic disorders including metabolic syndrome (MetS),type 2 diabetes (T2DM) and cardiovascular diseases (CVD).The incidence of obesity has increased dramatically in recent years worldwide.In China,more than one-third of adults are overweight or obese and 10%-20% of all adults are affected by MetS.The pathogenesis underlying the abdominal obesity remains unclear.The ultimate health outcome of obesity and its related metabolic disorders have prompted physicians to take aggressive treatments (lifestyle changes,pharmacological interventions and surgical therapies) before a serious consequence becomes clinically apparent.In this review,we discuss the prevalence,pathogenesis and clinic features of obesity in China. | WEI-PING JIA ,CHEN WANG,SHAN JIANG,AND JIE-MIN PAN Department of Endocrinology and Metabolism,Shanghai Jiao Tong University Affiliated Sixth People’s Hospital,Shanghai Diabetes Institute,Shanghai Clinical Center of Diabetes,Shanghai 200233,China | 2010 | Biomedical and Environmental Sciences2010，23，1： | 46 |
| 2 | Metabonomic phenotype and identification of “heart blood stasis obstruction pattern” and “qi and yin deficiency pattern” of myocardial ischemia rat models显示文摘The traditional Chinese medicine concepts of 'Xinxueyuzuzheng (heart blood stasis obstruction pattern)' and 'Qiyinliangxuzheng (qi and yin deficiency pattern)' for myocardial ischemia rat models were constructed in the present study. Endogenous metabolites in rat plasma were analyzed using the GC/TOF-MS-based metabonomic method. Significant metabolic differences were observed between the control and two model groups, and the three groups were distinguished clearly by pattern recognition. Compared with those of the control, the levels of hydroxyproline, threonic acid, glutamine and citric acid were strikingly up or down-regulated in model rats. The metabolites contributing most to the classification between the two 'pattern' rats were identified, such as valine, serine, threonine, ornithine, hydroxyproline, lysine, 2-hydroxybutanoic acid, 3-hydroxybutanoic acid, galactofuranose and inositol. These compounds were indicated as the potential biomarkers. The results suggested that the two 'patterns' are involved in dysfunction in oxidative stress, energy metabolism and amino acid metabolism. These findings also provided the substantial foundation for exploring the scientific connotation of these two 'Zhengxing (pattern types)' of myocardial ischemia, and 'Bianzheng (pattern identification)'. | YAN Bei1, A JiYe1, HAO HaiPing1, WANG GuangJi1, ZHU XuanXuan2, 3, ZHA WeiBin1, LIU LinSheng1, GUAN EnZe3, ZHANG Ying1, GU ShengHua1, HUANG Qing1 & ZHENG YuanTing1 1Key Laboratory of Drug Metabolism and Pharmacokinetics, China Pharmaceutical University, Nanjing 210009, China 2Pharmacological Laboratory of Clinical Research Institute, Jiangsu Provincial Hospital of Traditional Chinese Medicine, Nanjing 210029, China 3College of Pharmacy, Nanjing University of Traditional Chinese Medicine, Nanjing 210029, China | 2009 | Science China(Life Sciences)2009，52，11： | 19 |
| 3 | Cloning of cytochrome P-450 2C9 cDNA from human liver and its expression in CHL cells显示文摘AIM: Using bacterial, yeast, or mammalian cell expressing a human drug metabolism enzyme would seem good way to study drug metabolism-related problems. Human cytochrome P-450 2C9 ( CYP2 C9) is a polymorphic enzyme responsible for the metabolism of a large number of clinically important drugs. It ranks among the most important drug metabolizing enzymes in humans. In order to provide a sufficient amount of the enzyme for drug metabolic research, the CYP2 C9 eDNA was cloned and expressed stably in CHL cellsMETHODS: After extraction of total RNA from human livertissue, the human CYP2C9 eDNA was amplified withreverse transcription-polymerase chain reaction (RT-PCR),and cloned into cloning vector pGEM-T. The cDNA fragmentwas identified by DNA sequencing and subcloned into amammalian expression vector pREP9. A transgenic cell linewas established by transfecting the recombinant vector ofpREP9-CYP2C9 into CHL cells. The enzyme activity ofCYP2C9 catalyzing oxidation of tolbutamide to hydroxytolbutamide in S9 fraction of the cell was determined by highperformance liquid chromatography(HPLC).RESULTS: The amino acid sequence predicted from theeDNA segment was identical to that of CYP2 C9 * 1, the wildtype CYP2 C9. However, there were two base differences, i.e. 21T > C, 1146C > T, but the encoding amino acidsequence was the same, L7, P382. The S9 fraction of theestablished cell line metabolizes tolbutamide to hydroxytolbutamide; tolbutamide hydroxylass activity was found to be0.465 ± 0.109 μmol@ min-1 . g1 S9 protein or 8.62 ± 2.02 mol@ min 1 ~mol-1 CYP, but was undetectable in parental CHL cell.CONCLUSION: The cDNA of human CYP2C9 was successfullycloned and a cell line of CHL- CYP2C9, efficiently expressingthe protein of CYP2C9, was established. | Ge-Jian Zhu Ying-Nian Yu,Department of Pathophysiology and Laboratory of Medical Molecular Biology,Zhejiang University School of Medicine,Hangzhou 310031,Zhejiang Province,China Xin Li,Department of pharmaceutical analysis & drug metabolism,College of Pharmacology Science,Zhejiang University,Hangzhou 310031,Zhejiang Province,China Yu-Li Qian, Present address:Center of laboratory,Women’s hospital,School of Medicine,Zhejiang University,Hangzhou 310031,Zhejiang Province,China | 2002 | World Journal of Gastroenterology2002，8，2： | 9 |
| 4 | Repair effect of diabetic ulcers with recombinant human epidermal growth factor loaded by sustained-release microspheres显示文摘In this study the w/o/w extraction–evaporation technique was adopted to prepare poly(lactic-co-glycolic acid) (PLGA) microspheres loading recombinant human epidermal growth factor (rhEGF). The micro-spheres were characterized for morphology by transmission electron microscopy (TEM) and particle size distribution. The release performances, the proliferation effects and therapeutic effects of rhEGF-loaded PLGA microspheres were all studied. The results showed that these spherical micro-spheres had a narrow size distribution and a high drug encapsulation efficiency (85.6%). RhEGF-loaded microspheres enhanced the growth rate of fibroblasts and wound healing more efficiently than pure rhEGF. The number of the proliferating cell nuclear antigen (PCNA) in the epidermis layer with the mi-crosphere treatment was significantly larger than those of the control groups. Overall locally sustained delivery of rhEGF from biodegradable PLGA microspheres may serve as a novel therapeutic strategy for diabetic ulcer repair. | DONG XiaoQing1, XU Jun2, WANG WeiCai1, Luo Hao1, LIANG XiaoFei1, Zhang Lei1, Wang HanJie1, Wang PengHua2 & CHANG Jin1 1 Institute of Nanobiotechnology, School of Materials Science and Engineering, Tianjin University, Tianjin 300072, China 2 Department of Diabetic Foot, Tianjin Medical University Metabolic Disease Hospital, Tianjin 300070, China | 2008 | Science China(Life Sciences)2008，51，11： | 7 |
| 5 | Comparative proteomic analysis of the response in resistant and susceptible maize inbred lines to infection by Curvularia lunata显示文摘Proteins differentially expressed from maize leaves in response to the infection by Curvularia lunata strain CX-3 were identified through a high-resolution two-dimensional gel electrophoresis (2-DE) method. Two inbred lines, 78599-1 and E28, were used, respectively, as resistant and susceptible lines to CX-3 infection. Proteins were extracted from the fourth leaves of sixor seven-leaf stage plants sampled at 24, 36, 48, 60, and 72 h after inoculation with CX-3. Twenty-seven differentially expressed protein spots resolved on the 2-DE gels were identified by MALDI-TOF MS/MS. The results showed that these proteins are associated with photosynthesis, respiration, oxidative and drought stress tolerance as well as signal transduction in maize. Among stress-related proteins, the 22 kDa drought-inducible protein, putative glutathione peroxidase (GPX), and translation initiation factor (eIF-5A) were up-regulated in the resistant inbred line and were implicated in host defense response to C. lunata infection. It suggests that drought-inducible and oxidation stress-related proteins might directly contribute to maize resistance to C. lunata. | Xiuli Huang 1, Lixing Liu 1, Jie Chen Yuhong Zhai Department of Plant Science, School of Agriculture and Biology, Key Laboratory of Microbial Metabolism, Ministry of Education, Shanghai Jiaotong University, Shanghai 200240, China | 2009 | Progress in Natural Science:Materials International2009，19，7： | 6 |
| 6 | Las-like quorum-sensing system negatively regulates both pyoluteorin and phenazine-1-carboxylic acid production in Pseudomonas sp. M18显示文摘A las-like quorum-sensing system in Pseudomonas sp. M18 was identified, which consisted of lasI and lasR genes encoding LuxI-LuxR type regulator. Several functions of the las system from strain M18 were investigated in this study. The chromosomal inactivation of either lasI or lasR by recombination increased the production of both pyoluteorin (Plt) and phenazine-1-carboxylic acid (PCA) by 4-5 fold and 2-3 fold over that of the wild type strain of M18, respectively. Production of both antibiotics was restored to wild-type levels after in trans complementation with the wild-type lasI or lasR gene. Expression of the translational fusions pltA'-'lacZ and phzA'-'lacZ further confirmed the negative effect of lasI or lasR on both biosynthetic operons, and it was also demonstrated that the las system was related to the ability of swarming motility and the inhibition of cell growth. | CHEN Yun, WANG XiaoLei, HUANG XianQing, ZHANG XueHong & XU YuQuan Key Laboratory of Microbial Metabolism of Ministry of Education, College of Life Sciences and Biotechnology, Shanghai Jiao Tong University, Shanghai 200240, China | 2008 | Science China(Life Sciences)2008，51，2： | 5 |
| 7 | LysR family factor PltR positively regulates Pyoluteorin production in a pathway-specific manner in Pseudomonas sp. M18显示文摘The pltR gene, coding a putative LysR-type regulator, was identified upstream Plt biosynthetic gene cluster in Pseudomonas sp. M18 using bioinformatics technology. The null mutation of pltR resulted in mutant M18TRG (pltR::Gm) by recombination and its Plt (Pyoluteorin) production declined to 30% while PCA (Phenazine-1-carboxylic acid) production remained unchanged as compared with the wild-type M18 grown in King’s Medium B. After complementation, Plt production of mutant M18TRG was restored to the level in wild-type M18. Overexpression of pltR in M18 led to 13-fold enhancement of Plt produc-tion over the wild-type M18 strain. However, PCA production was unchanged under this condition. These data suggested that PltR was a positive regulator on Plt production. Plt itself, however, could not regulate expression of pltR. Expression of the plt-lacZ transcriptional fusion in mutant M18TRG de-clined obviously as compared with the wild-type M18, which further proved that PltR could regulate expression of Plt biosynthetic genes at the transcriptional level. In addition, the investigation on the pltR expression in gacA mutant M18G and rsmA mutant M18R disclosed that PltR was involved in the positive regulation of gacA on Plt production while being excluded from the negative control caused by rsmA. | YAN An, WANG XiaoLei, ZHANG XueHong & XU YuQuan Key Laboratory of Microbial Metabolism of Education Ministry, College of Life Sciences and Biotechnology, Shanghai Jiao Tong University, Shanghai 200240, China | 2007 | Science China(Life Sciences)2007，50，4： | 5 |

| 9 | Analysis of species-dependent hydrolysis and protein binding of esmolol enantiomers显示文摘The stereoselective hydrolysis of esmolol in whole blood and in its separated components from rat,rabbit and human was investigated.Blood esterase activities were variable in different species in the order of rat>rabbit>human.Rat plasma showed the high esterase activity and had no stereoselectivity to enantiomers.Rabbit red blood cell(RBC) membrane,RBC cytosol and plasma all hydrolyzed esmolol but with different esterase activity,whereas the hydrolysis in RBC membrane and cytosol showed significant stereoselectivity towards R-(+)-esmolol.Esterase in RBC cytosol from human blood mainly contributed to the esmolol hydrolysis,which was demonstrated with no stereoselctivity.Esterase in human plasma showed a low activity,but a remarkable stereoselectivity with R-(+)-esmolol.In addition,the protein concentration affected the hydrolysis behavior of esmolol in RBC suspension.Protein binding of esmolol enantiomers in human plasma,human serum albumin(HSA) and α_1-acid glycoprotein(AGP) revealed that there was a significant difference in bound fractions between two enantiomers,especially for AGP.Our results indicated that the stereoselective protein binding might play a role in the different hydrolysis rates of esmolol enantiomers in human plasma. | Yi-Hong Tanga,b,1,Jun-Yan Wanga,1,Hai-Hong Hua,Tong-Wei Yaoa,Su Zenga,n aDepartment of Pharmaceutical Analysis and Drug Metabolism,College of Pharmaceutical Sciences,Zhejiang University,Hangzhou,Zhejiang 310058,People’s Republic of China bShanghai Institute of Technology,Shanghai 201418,People’s Republic of China | 2012 | Journal of Pharmaceutical Analysis2012，2，3： | 3 |
