ObjectiveTo investigate the inhibitory effect of peroxisome proliferator-activated receptor-?(PPAR?) agonist on mesangial cell(MC) proliferation and extracellular matrix expression induced by angiotensin Ⅱ(Ang Ⅱ).MethodsThe incorporation of 3H-thymidine(3H-TdR) and cell count were used as the measurement of MC proliferation.MC cell-cycle was analyzed by flow cytometry.Mouse primary MC was treated with various concentration of Ang Ⅱ(1,10,100 nmol/L) in the presence or Absence of N-acytosistin(NAC) or rosiglitazone.Transforming growth factor-?1(TGF-?1),plasminogen activator inhibitor-1(PAI-1),and fibronectin(FN) mRNA expression were determined by real time-PCR.Reactive oxygen species(ROS) production was measured by 2,7-dichlorofluorescein diacetate(DCFDA) fluorescence.Results1.One hundred nmol/L Ang Ⅱ increased 3H-TdR incorporation and cell number by 2.14 and 2.32 fold,respectively.Ang Ⅱ-induced MC proliferation was inhibited by PPAR? agonist rosiglitazone with dose-dependent manner in mouse MC.2.One hundred nmol/L Ang Ⅱ stimulation for 24 h induced 48% MC processed to S and G2/M phase.Rosiglitazone significantly blocked Ang Ⅱ increased cell number in S and G2/M phase.3.Rosiglitazone reduced Ang Ⅱ-induced TGF-?1,PAI-1,and FN mRNA expression with dose-dependent manner.4.One hundred nmol/L Ang Ⅱ stimulation for 60 min increased ROS production by 3.85 folds.Rosiglitazone significantly inhibited Ang Ⅱ-induced ROS production.Ten ?mol/L rosiglitazone almost completely blocked Ang Ⅱ-induced ROS production.ConclusionPPAR? agonist rosiglitazone could block Ang Ⅱ-induced MC proliferation and extracellular matrix expression via inhibition of ROS production.

AIM:To observed the variation regularity of corneal endothelial cells in patients with different diabetes duration after phacoemulsification, and investigate the effects of diabetes and its disease duration on corneal endothelial cells.
METHODS: Ninety-seven ( 135 eyes ) cataract patients with diabetes were selected randomly and divided into GroupⅠ( which diabetes duration ≥10a) and GroupII(which diabetes duration <10a) according to their disease duration. Additionally 62 (89 eyes) age-related cataract patients were randomly selected as the control group. The corneal endothelial cell density ( CD ) , proportion of hexagonal cell and coefficient of variation ( CV ) in the three group patients were measured respectively before phacoemulsification and after surgery. And the measurement results were statistically analyzed.
RESULTS:The corneal endothelial CD and proportion of hexagonal cell in the three group were decreased after surgery compared with preoperative. But the CV of corneal endothelial cells was increased on the 1 st wk and in 1st mo after surgery compared with the preoperative. The difference was statistically significant (P<0. 05). The corneal endothelial CD and proportion of hexagonal cell in the two diabetic groups were lower than the control group after surgery. However, the CV of corneal endothelial cells was higher than the control group. The difference was statistically significant ( P < 0.05 ) . There was no significant difference in the corneal endothelial CD, proportion of hexagonal cell and CV between the two diabetic groups before phacoemulsification (P>0. 05). The proportion of hexagonal cell in Group Ⅰ was lower than which in GroupIIafter surgery. While the CV was higher than which in Group II. The difference was statistically significant (P<0. 05).
CONCLUSION: Phacoemulsification has some damage on the corneal endothelial. Since the impact of diabetes on the morphology and function of corneal endothelial cell was related to the diabetic duration. So phacoemulsification has more obvious damage on the corneal endothelial in diabetic patients. And the diabetic duration was longer, the damage on the corneal endothelial in phacoemulsification was more easily.

In order to promote the Shenqifuzheng injection (SQFZ) clinical medication safety, this study reevaluate on SQFZ post marketing safety study systematically. Including multi center large sample registration type safety monitoring research, the analysis based on national spontaneous reporting system data, the analysis based on the 20 national hospital information system data and literature research. Above the analysis, it suggests that SQFZ has good security. The more adverse drug reaction (ADR) as allergic reactions, mainly involved in the damage of skin, appendages and its systemic damage, serious person can appear allergic shock. ADR/E is more common in the elderly, may be related to medication (tumor) populations. Early warning analysis based on SRS data and literature research are of the view that "phlebitis" has a strong association with SQFZ used.

?AIM: To observed the clinical effect of twice fluid-gas exchange in vitrectomy for retinal detachment at the equator.?METHODS: The retrospective analysis of the 74 cases (74 eyes) with retinal detachment at the equator from January 2014 to September 2015 were reviewed. All these patients were performed standard three channel 23G vitrectomy under a wide angle lens, in which, the 37 cases ( 37 eyes ) were randomly selected and performed single fluid-gas exchange, and the other 37 cases ( 37 eyes) were performed twice fluid-gas exchange. The intraoperative surgical complications and the postoperative success rate of retinal reposition in 1wk, 1, 3mo after surgery of the two group patients were observed.? RESULTS: The intraoperative surgical complication rates of the twice fluid-gas exchange group were less than that of the single fluid-gas exchange group. The postoperative success rate of retinal reposition in the twice fluid-gas exchange group significantly increased in 1wk and 1mo after surgery, and the difference was statistically significant (P<0. 05). But the postoperative success rate of retinal reposition in 3mo after surgery had no significant difference (P>0. 05).?CONCLUSION:The twice fluid-gas exchange operation was simple and it was beneficial for beginners to master. The incomplete drainage of the single fluid-gas exchange and the pore drainage in the posterior pole or in the peripheral part of the retina were avoided during the surgery. The intraoperative surgical complication rates were reduced and the postoperative success rate of retinal reposition were improved. This operation method had great application value in clinic.

AIM:To observe the effects of Dickkopf-3 ( Dkk-3 ) in diabetic retinopathy ( DR ) circulating blood in patients with the expression level, the Dkk - 3 development changes in the diabetic retinopathy of significance in the diagnosis of early DR.
● METHODS: Eighty - five type 2 diabetic patients, included the non - proliferative diabetic retinopathy ( NPDR ) 23 patients, proliferative diabetic retinopathy, proliferative DR ( PDR ) in patients with 30 and non-diabetic retinopathy ( NDR ) with 32 cases. The same period of healthy physical examination was selected as control group ( 80 cases ) . Serum samples were collected, and the relative expression level of Dkk-3 was detected by enzyme - linked immunosorbent assay ( ELlSA) double antibody sandwich assay. The statistical differences were compared between groups.

OBJECTIVETo determine the different rates of human papillomavirus types 6 (HPV-6) and 11 (HPV-11) infection in biopsy samples from pointed condyloma patients, and to construct prokaryotic expression system of the major capsid protein L1 of the virus so as to establish an ELISA for detecting the expression of L1 gene in the biopsy samples.

METHODSUsing a double PCR based on the L1 gene of HPV-6 and HPV-11, the infection rates of HPV-6 and HPV-11 in the biopsy samples were determined. The whole length of HPV-6 L1 gene was amplified using PCR and the target amplification fragment was sequenced after T-A cloning. The prokaryotic expression system pET32a-L1-E. coli BL21 (DE3) was constructed and SDS-PAGE was used to measure the expression of the target recombinant protein rL1. Rabbit anti-rL1 serum was prepared and immuno-diffusion assay was applied to examine the antiserum titer. ELISA was established to detect the expression of L1 gene in the biopsy samples.

RESULTSIn the biopsy samples from 116 pointed condyloma patients, 92.2% (107/116) were detectable for HPV-6 and/or HPV-11. Of the 107 positive samples, 70.1% (75/107) and 23.4% (25/107) were positive for HPV-6 or HPV-11 alone and 6.5% (7/107) were coinfected with both HPV-6 and HPV-11 respectively. When compared with the reported corresponding sequences, the homology of nucleotide and sequence of the cloned HPV-6 L1 gene was from 99.20% - 99.93% while its putative amino acid sequence homology was from 99.80% - 100%, suggesting IPTG could induce the expression of rL1. The immuno-diffusion titer of the rabbit anti-rL1 serum was 1:4. 88.8% (103/116) of the biopsy samples were the major capsid protein L1 detectable.

CONCLUSIONA prokaryotic expression system of HPV-6 L1 gene, a double PCR assay for HPV-6 and HPV-11 genotyping, and an ELISA assay for detecting the major capsid protein L1 were successfully established in this study. The pointed condyloma patients in Zhejiang area mainly infected with HPV-6. The HPV in the focus frequently expressed major capsid protein L1.
