Objective To investigate the effects of adiponectin on cell activity and expression of T-cadherin in human retinal pigment epithelial(hRPE) cells cultured with high glucose.Methods ①The hRPE cells were divided into three groups:normal glucose group(5.5mmol/L glucose),high glucose group (33mmol/L glucose),high glucose plus adiponectin group (33mmol/L glucose+2.5ug/ml adiponectin).48h later,the cell activity was observed by MTT assay.②After the above groups were cultured respectively for 24h,48h,72h again,the expression of T-cadherin mRNA was observed by RT-PCR. Results ①Cell activity in high glucose group significantly decreased. Cell activity adiponectin group was higher than that in the high glucose group.②With the extension of time ,the expression of T-cadherin decreased in high glucose group,but increased in adiponectin group.

7.Expression of c-met stimulated by high glucose in human renal tubular epithelial cells and its implication.
Journal of Huazhong University of Science and Technology (Medical Sciences) 2007;27(2):161-3
The expression of c-met stimulated by high glucose in human renal tubular epithelial cells and the role of HGF/c-met system in diabetic nephropathy were examined. The proximal tubular epithelial cells were cultured in vitro under different conditions. MTT was used for the detection of cellular proliferation and RT-PCR was employed for measurement of c-met mRNA level. Our results showed that under different conditions, there were no significant differences in the proliferation of proximal tubular epithelial cells 12 h and 24 h after the culuture (P>0.05). The proliferation of proximal tubular epithelial cells showed a significant change 96 h after the culture and the cellular proliferation induced by hepatocyte growth factor (HGF) was very active (P<0.05). Moreover, no significant difference in the expression of c-met mRNA was found 12 h after the culture under different conditions (P>0.05), while 24 and 96 h after the culture, a persistent and significantly higher expression of c-met mRNA was found in HGF-induced proliferation. It is concluded that addition of exogenous HGF could inhibit the apoptosis induced by high-level glucose, promote the proliferation of proximal tubular epithelial cells, and induce the expression of c-met. Our study suggests that local up-regulation of HGF/c-met system plays an important role in the repair of renal damage in diabetic nephropathy.
8.Expression of connexin 43 in ovarian cancer and its relationship with chemoresistance
Chinese Journal of Obstetrics and Gynecology 2009;44(1):50-55
Objective To examine the expression of protein kinase C (PKC), connexin43(Cx43) and non-phosphorylated Cx43 in ovarian cancer, and discuss the role of phosphorylated of Cx43 in chemoresistance in ovarian cancer. Methods We examined the expression of Cx43, non-phosphorylated Cx43 and PKC in ovarian cancer tissue by immunohistochemistry, and compared their expression in chemosensitivity group and ehemoresistance group. Cisplatin resistant ovarian cancer cell line SKOV3/DDP cells were treated by staurosporine (a kind of PKC inhibitors). Then expression of Cx43, non-phosphorylated Cx43 and PKC were tested. Meanwhile, we tested chemosensitivity of SKOV3/DDP cells by ATP bioluminescence tumor chemosensifivity assay (ATP-TCA). Results (1) Immunohistochemically,the rates of positive expression of Cx43 and non-phospharylated Cx43 were 54%, 14% respectively in the chemoresistance group, which were 83%, 59% in the chemosensitivity group respectively (P<0.05). The rate of positive expression of PKC in 28 chemoresistance ovarian cancer cases (64%) was higher than that in 29 chemosensitivity cases (31% ,P<0.05). Both of them were significantly lower in ehemoresistanee group than in chemosensitivity group (P<0.05). In addition, the expression of PKC was negatively correlated with the expression of Cx43 and non-phosphorylated Cx43. The correlation coefficients were -0. 626 and -0. 714, respectively (P<0.05). (2) Immunohistochemically, PKC was down regulated, and Cx43 and non-phosphorylated Cx43 were up regulated in SKOV3/DDP cells after staurosporine treatment. The longer the staurosporine worked, the more expression of Cx43 was. (3) By ATP-TCA, SKOV3/DDP cells were resistant to paclitaxel and cisplatin. The tumor growth inhibition was higher in the group of paclitaxel or cisplatin combined staurosporine than in the group of paclitaxel or cisplatin alone. The sensitivity was intermediate in the group combined with low concentration staurosporine (1×10-8 moL/L), and the sensitivity was high in the group combined with high concentration staurosporine (1×10-7 mol/L). Conclusions Phosphorylation of Cx43 caused by PKC leads to decrease in the expression of Cx43. This effect makes ovarian cancer cells less chemosensitive. Phosphorylation of Cx43 caused by PKC can be inhibited by staurosporine.
9.Current status of mechanical thrombectomy for acute ischemic stroke
International Journal of Cerebrovascular Diseases 2016;24(1):63-67
Before irreversible neuronal damage occurs, quickly and securely recanalize vessels and restore blood flow to save the ischemic penumbra tissue are the main therapeutic target for acute ischemic stroke (AIS). Currently, the method for recanalization in early AIS is intravenous thrombolysis, how ever, the effect of intravenous thrombolysis is often not satisfactory because of the reasons, such as its short treatment time w indow , low vascular recanalization rate, and high incidence of bleeding complications. In recent years, w ith the research and development of mechanical thrombectomy device and the development of interventional technology, the therapeutic time w indow of AIS has been significantly prolonged, the vascular recanalization rate has increased significantly, the clinical outcome has improved significantly, and the treatment of mechanical thrombectomy has show n good application prospects.
