Objective To explore the effects of dexamethasone on ovulation induction in polycystic ovary syndrome (PCOS).Methods This clinical study included 68 women with PCOS, which of them were divided into two groups: 34 in dexamethasone treating(dexamethasone combined with ovulation induction) and 34 in con-trol(ovulation induction treatment only).Subsequently, comparisons were made between pre and after drug treat-ment in two groups, the main indexes were the levels of testosterone(T), luteinizing hormone(LH), follicle stim-ulating hormone(FSH), growth rate of follicle, and body mass index(BMI).And we have also considered the o-vulation rate and pregnancy rate, and compared these indexes in dexamethasone treating group with control group.Results There were significant differences between pre and after dexamethasone treatment in the levels of T in treatment group(P < 0.01), and there were not significant differences between pre and after treatment in the lev-els of T in control group (P >0.05).LH had decreased significantly after treatment in both two groups (P <0.01), FSH had not significant differences between pre and after treatment in two groups(P >0.05).The growthrate of follicle of two groups had elevated after treatment (P < 0.01).And the ovulation rate in dexamethasone treating group was higher than that in control group(P < 0.05), but there were not significant differences between the two groups in the clinical pregnancy rates(P >0.05).There were not significant differences between pre and after treatment in the levels of BMI in both two groups (P > 0.05).Conclusions Dexamethasone can decrease the T in plasm levels.It is good for ovulation induction in PCOS.

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.

Objective:To investigate the effects of the psychological stress on peripheral blood lymphocytes apoptosis and Bax,Bcl-2 gene expression in rats after being given different intensity of noise stress.Methods:All 24 SD rats were divided into three groups:control,high intensity of the noise stress,middle intensity of the noise stress. The apoptosis in peripheral blood lymphocytes(PBL)of rats was demonstrated with the flow cytometer to determine the percentages of apoptosis in rat PBL,and the expression changes of related Bcl-2,Bax genes were observed by us- ing immunohistochemical method.Results:1)After high intensity of the noise stress for three weeks,the apoptosis in rat PBL increased significantly compared with the control.2)After high intensity of the noise stress for three weeks, Bcl-2 expression as down-regulation in PBL,but the B ax expression remained obviously high.Conclusion:It indi- cates that apoptosis exists in the immunocytes of rats in the course of high intensity of the psychological stress and it consists with the expression of the related regulatory genes.

objective: To improve the repair technique of secondary nasal deformity following surgical treatment in the patients with bilateral cleft lip. Methods: 12 cases were treated with the operation technique: bilateral vermilion flaps were inserted into prolabial for the enlongation of upper lip and "V Y incision suture" principle was employed to repaire the nasal deformity. Results: Satisfactory results were achieved in all the 12 cases. Conclusion: The technique is feasible in the reconstruction of Cupid's bow, philtrum and correction of nasal and labia deformities.

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.

Bis-(3′,5′) cyclic di-guanylate (c-di-GMP) is an almost ubiquitous intracellular second messenger in bacteria.Now it is known to regulate complex physiological processes, including mobility, adhesion, virulence and biofilm formation.The level of c-di-GMP is regulated by diguanylate cyclases (DGCs) containing GGDEF domains and phosphodiesterases (PDEs) containing EAL or HD-GYP domains.Recent studies have demonstrated that HD-GYP domain protein is a novel phosphodiesterase, which is also involved in the regulation of c-di-GMP degradation.This review highlights recent advances in the structure and biochemical functions of HD-GYP domain proteins, which might help to further clarify the mechanism of c-di-GMP signal system.
