Objective To investigate the effect of over-expressed Cyr61 on the expression of extracellular matrix of human renal tubular epithelial cells(HKC), and explore the role of Cyr61 in the pathogenesis and development of autosomal dominant polycystic kidney disease(ADPKD). Methods Cyr61 gene cDNA was amplified by RT-PCR. A recombinant plasmid pcDNA3.1+ Cyr61 was constructed by cloning Cyr61 gene into pcDNA3.1. HKC cells were transfected with wild-type Cyr61 plasmid vector (pcDNA3.1+Cyr61). Then the fusion of Cyr61 gene and expression of its protein were detected by RT-PCR and Western blot. The mRNA expression of Cyr61, collagen Ⅰ, collagen Ⅳ, and laminin were determined in four groups (the untransfected cells, pcDNA3.1 transfected cells, pcDNA3.1+Cyr61 -transfected cells and cyst-lining epithelial cells) by fluorescence quantum PCR. Results The amount of Cyr61 protein in Cyr61-transfected cells and cyst-lining epithelial cells were much greater than the control. The mRNA expression of Cyr61, collagen Ⅰ, collagen Ⅳ and laminin in Cyr61-transfected cells were all amplified significantly, and the level of collagen Ⅳwas much higher than collagen I(P

The metabolic characteristics of ligustrazin (TMPz) in liver microsomes were investigated in the present study. The reaction phenotyping of TMPz metabolism was also identified by in vitro assessment using recombinant human cytochrome P450 enzymes (CYP) and UDP glucuronosyltransferases (UGT). TMPz was incubated at 37 degrees C with human (HLM) and rat liver microsomes (RLM) in the presence of different co-factors. The metabolic stability and enzyme kinetics of TMPz were studied by determining its remaining concentrations with a LC-MS/MS method. TMPz was only metabolically eliminated in the microsomes with NADPH or NADPH+UDPGA. In the HLM and RLM with NADPH+UDPGA, t1/2, K(m) and V(max) of TMPz were 94.24 +/- 4.53 and 105.07 +/- 9.44 min, 22.74 +/- 1.89 and 33.09 +/- 2.74 micromol x L(-1), 253.50 +/- 10.06 and 190.40 +/- 8.35 nmol x min(-1) x mg(-1) (protein), respectively. TMPz showed a slightly higher metabolic rate in HLM than that in RLM. Its primary oxidative metabolites, 2-hydroxymethyl-3, 5, 6-trimethylpyrazine (HTMP), could undergo glucuronide conjugation. The CYP reaction phenotyping of TMPz metabolism was identified using a panel of recombinant CYP isoforms (rCYP) and specific CYP inhibitors in HLM. CYP1A2, 2C9 and 3A4 were found to be the major CYP isoforms involved in TMPz metabolism. Their individual contributions were assessed b) using the method of the total normalized rate to be 19.32%, 27.79% and 52.90%, respectively. It was observed that these CYP isoforms mediated the formation of HTMP in rCYP incubation. The UGT reaction phenotyping of HTMP glucuronidation was also investigated preliminarily by using a panel of 6 UGT isoforms (rUGT). UGT1A1, 1A4 and 1A6 were the predominant isoforms mediated the HTMP glucuronidation. The results above indicate that the metabolism of TMPz involves multiple enzymes mediated phase I and phase II reactions.

Introduction: Tuberculosis (TB) in internal migrants is one of three threats for TB control in China. To address this threat, a project was launched in eight of the 19 districts of Shanghai in 2007 to provide transportation subsidies and living allowances for all migrant TB cases. This study aims to determine if this project contributed to improved TB control outcomes among migrants in urban Shanghai.
Methods: This was a community intervention study. The data were derived from the TB Management Information System in three project districts and three non-project districts in Shanghai between 2006 and 2010. The impact of the project was estimated in a difference-in–difference (DID) analysis framework, and a multivariable binary logistic regression analysis.
Results: A total of 1872 pulmonary TB (PTB) cases in internal migrants were included in the study. The treatment success rate (TSR) for migrant smear-positive cases in project districts increased from 59.9% in 2006 to 87.6% in 2010 (P < 0.001). The crude DID improvement of TSR was 18.9%. There was an increased probability of TSR in the project group before and after the project intervention period (coefficient = 1.156, odds ratio = 3.178, 95% confidence interval: 1.305–7.736, P = 0.011).
Conclusion: The study showed the project could improve treatment success in migrant PTB cases. This was a short-term programme using special financial subsidies for all migrant PTB cases. It is recommended that project funds be continuously invested by governments with particular focus on the more vulnerable PTB cases among migrants.

Objective To investigate the clinical and molecular pathological features of dysferlinopathy in China.Methods Four patients with limb-girdle muscular dystrophy2B(LGMD2B)and 4 patients with Miyoshi-type distal muscular dystrophy(MMD)were clinically analyzed, their skeletal muscle were biopsied and immunohistochemical stained.Four cases of each Duchenne-Aran muscular atrophy and myotis were served as controls.Results The clinical situation of dysferlinopathy was characterized by progressive muscle weakness and atrophy, consistent with progressive muscular dystrophy.Histochemical staining revealed muscle fibers degenerating, regenerating and necrosis in a varying degree.Connective tissue was seen proliferated and inflammatory cells infiltrated in the majority of cases.Immunohistochemical staining with anti-dysferlin monoclonal antibody identified the deficiency of dysferlin on the sarcolemma and in the sarcoplasm of 8 cases with dysferlinopathy.Conclusions(1)The clinical and pathological characters of dysferlinopathy are consistent with progressive muscular dystrophy;(2)Anti-dysferlin monoclonal antibody immunohistochemical staining is a reliable method to diagnose dysferlinopathy, which is worth of wide application in clinic.

Objective To investigate the correlation between the ratio change of circulating myeloid-derived suppressor cells (MDSCs) and cellular immune function in healthy volunteers,chronic gastritis patients,gastric intraepithelial neoplasia patients and gastric cancer patients.Methods From February 2011 to July 2011,129 peripheral blood samples were collected,including 32 healthy volunteers,48 chronic gastritis patients,27 gastric intraepithelial neoplasia patients and 22 gastric cancer patients.The percentages of peripheral blood MDSC,T lymphocyte subsets and regulatory T cells (Treg) were determined by flow cytometry.The data were analyzed by one way analysis of variance,pearson and spearman correlation.Results The percentages of circulating MDSC,CD8+ T lymphocyte and Treg were highest in gastric cancer patients (9.63%±3.24%,10.03% ± 1.26%,69.45%±3.42%) and lowest in healthy volunteers (0.92%±0.33%,4.12% ±0.99%,32.35% ±4.83%).Those of gastric intraepithelial neoplasia patients (5.13% ± 1.30%,7.54% ± 0.79%,53.26%±4.30%) were lower than gastric cancer patients but higher than chronic gastritis patients (2.76% ±0.64%,6.28% ±0.61%,42.37% ±4.02%).The differences among each groups were statistically significant (F=24.85,20.88,37.84,all P<0.05).However,the percentage of circulating CD4+T lymphocyte was highest in healthy volunteers (65.10%±4.10%),55.15% ± 4.00% in chronic gastritis group,42.23% ± 3.91% in gastric intraepithelial neoplasia group,and lowest in gastric cancer group (26.84% ± 3.69%).The differences among each groups were statistically significant (F=46.80,P<0.05).A significant correlation between circulating MDSC and TNM stages of gastric cancer was also observed (r=0.856,P<0.01).The percentage of circulating MDSC was positively correlated with Treg percentage (r =0.862,P < 0.01),and negatively correlated with CD4+/CD8+ ratio (r=-0.768,P<0.01).Conclusion The increase of MDSC percentage in peripheral blood is correlated with human cellular immune function,which might play an important role in the tumor immune evasion during the development of gastric cancer.
