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.

OBJECTIVE:To study the preparation and in vitro dissolution of ethyl pepper solid dispersion. METHODS:Sol-vent-melting method was adopted. Using polyethylene glycol 6000(PEG-6000)as carrier,the effects of different drug-loading ratios (1∶1,1∶5,1∶7,1∶10,1∶15,1∶18,1∶20)on the dissolution of ethyl pepper solid dispersion was invesigated. The stability of crude drug ethyl pepper at 85℃was determined. Furthermore,differential scanning calorimetry and X-ray powder diffraction meth-od were used to identify the existence of ethyl pepper in the solid dispersion. RESULTS:The dissolution of ethyl pepper could be improved by mixing ethyl pepper and PEG-6000 in a ratio of 1∶15,and the preparation was maintained stable at 85 ℃. The drugs part of ethyl pepper-PEG-6000 solid dispersions existed in the form of amorphous or molecular. CONCLUSIONS:The dissolution of ethyl pepper solid dispersion can be improved significantly by mixing ethyl pepper and PEG-6000 (1∶15),and the dispersion keeps stable at 85℃. The study can provide reference for further study of the preparation technology of ethyl pepper preparation.

Objective To investigate the relationship between expression of eofilin-1 and in vivo implantation capacity of eutopic endometrium of endometriosis.Methods Eutopic endometrium of 20 cases with stage Ⅲ or Ⅳ endometriosis were obtained by laparoscopic or laparotomy surgery (endometriosis group) matched with 20 cases of eutopic endometrium from patients with cervical cancer in situ (control group) in Department of Obstetrics and Gynecology,ShengJing Hospital.All cases' eutopic endometrium were collected and injected into abdominal cavity of nude mice to establish endometriosis animal model, then the successful rate of animal model and volume of endometriosis lesion were calculated.The expression and positive rate of eofilin-1 protein were measured by western blot and immunohistochemistry staining.Results The mean volume of endometriosis lesions (2.38 ± 0.22)mm~3 in endometriosis group was significantly bigger than (0.36 ± 0.08) mm~3 in control group (P < 0.05).The successful rate of establishing endometriosis model was 95% (19/20) in endometriosis group and 5% (1/20)in control group, which reached statistical difference(P <0.05).The expression and positive rate of cofilin-1 protein in eutopic endometrium and the expression of cofilin-1 protein in endometriosis lesion of animal model were 0.82±0.06, 90% (18/20), 0.85 ± 0.03 and 0.21 ± 0.03, 20% (4/20), 0.22 ± 0.02 in control group, which reached statistical difference(P <0.05).The successful rate of establishing endometriosis model with positive cofilin-1 in endometrium 86% (19/22) was significantly higher than 6% (1/16) of model's endometrium with negative cofilin-1 expression(P <0.05).Conclusions Implanting capacity and cofilin-1 expression level of eutopic endometrium of endometriosis were more intensive than that of normal endometrium.High cofilin-1 expression was probably related with implanting capacity of eutopic endometrium of endometriosis.

Objective To investigate the relationship between neonatal health and TCM constitution types of early to mid-pregnancy expectant parents;To provide basis for the targeted interventions for couples of childbearing age before pregnancy-periconceptional TCM constitution. Methods Compiling scales for pregnant couple’ TCM constitution type assessment and postpartum visits to newborns, the research team got access to the information of neonatal physical problems, constitutions and changes of 675 babies’ father and mother who had established maternal manual from April, 2012 to March, 2013 at the Sanlin Community Health Center of Pudong District of Shanghai. Results Early to mid-pregnancy expectant parents mainly had peace constitution type. In detail, 55% of pregnant women had gentle constitution type, while others mainly had qi deficiency, yang deficiency and damp-heat constitution types;76% expectant fathers got peace constitution, while others mainly got damp-heat, yin deficiency and qi deficiency constitution types. Marital pregnancy physique did not change significantly. Compared with the peace constitution type, newborns, whose fathers got damp-heat constitution type, had higher risk of jaundice, and whose mothers got yin deficiency, the babies had higher risk of spits (P<0.05). The constitution types of expectant parents did not have obvious combined action on neonatal health. Conclusion There is a certain relationship between neonatal health and TCM constitution types of early to mid-pregnancy expectant parents. It is necessary to distinguish constitution types of prospective parents, and thus to take targeted health interventions.

The increase of blood-brain barrier (BBB) permeability is a key link in causing the pathological changes in vasogenic brain edema and inflammatory reaction. In recent years, a number of studies have indicaded that a lot of mediators participated in the structural and functional changes and damage of BBB during the process of cerebral ischemia-reperfusion.

AIM: To investigate cl in ical usage of drugs for respiratory system diseases. METHODS: Th e in-hospital records from November 2001 to February 2002 were investigated in a hospital. The usage and utilization of the drugs were analyzed with DDDs. Drug interactions were evaluated with a software (Reasonable Medication System). RESULTS: The frequency of use of antimicrobial accounted for 35% in total. The other two kinds were anti-asthma drugs and the removing fever of re ady-made traditional Chinese medicine. Some unreasonable interactions were foun d in this investigation. CONCLUSION: In the hospital, the usage of drugs for respiratory system diseases is rational on the whole, but drugs int eraction should not been neglected.

The effects of sodium salicylate on the expression of heat shock protein 27 (HSP27) during oxidative stress in tissue-cultured human lens epithelial cells were investigated. Cultured human lens epithelial cells (HLB-3) were divided into 3 groups: control group (group A), oxidation injury group (group B) and sodium salicylate group (group C). Apoptosis of human lens epithelial cells cultured in vitro was induced in the presence of 150 micromol/L H2O2. Cells viability and the expression of HSP27 were analyzed. Viability of the cells was measured by methyl thiazole tetrazolium (MTF) chromatometry. The expression of HSP27 in HLB-3 cells was detected by using immunohistochemistry and image analysis system. Sodium salicylate could induce the expression of HSP27, and the cells viability in group C was significantly higher than in group B (0.2667+/-0.01414 vs 0.2150+/-0.01080, P=0.012<0.05). The average gray value of HSP27 in group B was less than that in group C (P=0.000<0.05). The increased expression of HSP27 by sodium salicylate might play an important role in the protection of hydrogen peroxide-induced injury of human lens epithelial cells, suggesting that sodium salicylate could suppress, at least in part, the apoptosis of human lens epithelial cells.
