Objective To study the effect of calcitriol combined with metformin in the treatment of polycystic ovary syndrome(PCOS)and its influence on serum monocyte chemotactic factor -1(MCP -1).Methods 96 patients with PCOS were randomly divided into the control group(48 cases)and the the observation group(48 cases).The two groups were treated with metformin tablets,0.25g/time,2 times/d.On the basis of the above treatment,the observation group was given calcitriol,0.25μg/time,1 time /d.The two groups were treated for 3 months.Before and after treatment,the number of common symptoms of PCOS(menstrual scarce,acne,hairy,ovarian volume increase,polycystic change)and the determination of serum MCP -1 changes were summarized.Results Before treatment,the menstruation, acne,hairy,ovarian volume increase,polycystic change in control group were 46 cases,21 cases,32 cases,19 cases, 47 cases,respectively,which were 18 cases,11 cases,18 cases,9 cases and 10 cases after treatment.Before treatment, the menstruation,acne,hairy,ovarian volume increase,polycystic change in observation group were 47 cases,25 cases, 29 cases,22 cases,45 cases,respectively,which were 10 cases,6 cases,10 cases,4 cases and 5 cases after treatment. After treatment,the two groups were treated with less menstruation,acne,hair,ovarian volume and polycystic change (χ2 =9.86,7.25,9.06,10.17,13.42;14.28,12.62,11.28,16.52,19.66,all P <0.05).And after treatment, which of the observation group were significantly better than the control group (χ2 =4.06,4.86,5.62,4.71,9.27,all P <0.05).The serum MCP -1 levels of the control group before and after treatment were (159.64 ±27.12)μg/L, (118.54 ±21.38)μg/L,which of the observation group were (162.57 ±29.06)μg/L,(82.59 ±10.72)μg/L.After treatment,the serum levels of MCP -1 in the two groups were significantly decreased(t =2.968 2,4.163 8,all P <0.05),and the serum MCP -1 level in the observation group was significantly lower than that in the control group (t =2.661 2,P <0.05).Conclusion Calcitriol combined with metformin can significantly improve the efficacy of patients with PCOS,and decrease the expression of MCP -1 in serum.

Journal of Chongqing Medical University 1986;0(04):-
Objective:To observe the effect of GSK-3? on the cell cycle and metastasis of human gastric carcinoma cell.Methods:Influencing the GSK-3? activity of human gastric carcinoma cell line SCG-7901 by LY294002 with or with not LiCl treatment.The expression of total GSK-3? and p-GSK-3?ser9 were detected in protein level by western blotting,cell proliferation and cell cycle distribution were tested by MTT and FCM respectively,the expression of E-cadherin and ?-catenin were measured with S-P immunohistochemistry and the cell-ground substance adhesion was tested by cell adherence assay.Results:The expression of total GSK-3? was constant and the protein level of p-GSK-3? ser9 was down regulated after exposured to LY294002 by 72 h,the cell proliferation was inhibited,cell cycle was arrest at G0/G1 phase,the E-cadherin level was positively regulated,the expression of ?-catenin and the adhesion rate were decreased.The effect on the proliferation、cell cycle、the expression of E-cadherin and ?-catenin and the adhesion by the LY294002 were partially abrogated by lithium chloride.Conclusion:GSK-3?could negatively regulate the proliferation of human gastric carcinoma cell by leading cells to G1-S arrest and inhibit its metastasis by positively regulating the expression of E-cadherin.
9.Research of UVA in affecting Cx43 protein among rabbit lens epithelia cells
Journal of Chongqing Medical University 2007;0(07):-
Objective:To probe the mechanism of inhibition in gap junction-mediated intercellular communication (GJIC) of rabbit lens epithelia cells(RLECs) irradiated by UVA. Methods:RLECs of 2~3 generation were divided into normal control group and ultraviolet irradiation group (The UV intensity was 0.2 mW/cm2 under a UV lamp with fixed position 50 cm, RLECs were exposed to ultraviolet lamp at different times: 5,10,15 minutes). Western blot techniques were employed to detect the protein levels of Cx43 irradiated by UVA. By indirect immunofluorescence histochemistry we analyzed the localization of Cx43 in the RLECs. Results:In UVA irradiation group and normal control group,there was expression of Cx43. With the increasing intensity,the expression of Cx43 was decreasing. The immunnostaining of Cx43 in RLECs revealed that the internalization of Cx43 from membrance to plasma and nuclear was found in UVA irradiated RLECs. Conclusion: Cell molecule level study proved UVA irradiation can reduce GJIC of RLECs,which wis associated with perturbations in localization and number of Cx43 among RLECs.
