ObjectiveTo investigate the effect of weight self-management in reproductive-aged obese women with polycystic ovary syndrome(PCOS).Methods A total of 56 reproductive-aged obese women with PCOS were divided into two groups with the control group administered medicine to reduce the lipid,blood glucose and metformin and the experiment group managed with weight self-management in addition of the medicine treatment as in the control group.All of them were treated for six months.The number of women with oligomenorrhea,body mass index(BMI),waist-hip ratio(WHR),serum total cholesterol(TC),triglyceride(TG),fasting blood glucose(FBG), fasting insulin(FINS),homeostasis model assessment(HOMA)were measured before and after intervention for comparisons.Result The number of women with oligomenorrhea together with the levels of TC,TG,FBG,FINS and HOMA were significantly reduced in the two groups(allP<0.05),and the number of women with oligomenorrhea and the levels of BMI,TC and HOMA were decreased more than those in the control group(allP<0.05).Conclusion The weight self-management on the basis of drug therapy for reproductive-aged obese women with PCOS can significantly reduce the levels of BMI,WHR,TC,TG,FBG,FINS and HOMA,enhance the effect of drug therapy, reduce the incidence of oligomenorrhea and improve the metabolic disorders.

Objective:To detect tenascin(TN) expressions and its effect in salivary gland tumor. Methods:The expressions of TN was examined in 8 chronic inflammations of salivary glands, 50 benign adenomas and 57 malign adenomas by Envision immunohistochemical technique. Results:Expression level of TN in the malign adenomas was higher than that in benign adenoma and chronic sialadenitis; higher in low differentiation than that in high differentiation and higher in lymphatic metastasis groups than that without lymphatic metastasis groups. No obviously difference was found between soakage inside the blood vessel and nerves and without soakage. Conclusion: TN might regulate cell attachment of epithelial cells in adenomas, and involve in adenomas' histogenesis and development.

METHODS: Totally 25 cases ( 25 eyes ) of chronic dacryocystitis with lacrimal fistula were allocated into two groups:the double silicone intubation group of 13 cases (13 eyes) received lacrimal fistula excision combined with double silicone intubation, and the routine group of 12 cases (12 eyes) received routine dacryocystorhinotomy, we analyzed the curative effect.?RESULTS: The double silicone intubation group had a cure rate of 92. 3% (12 eyes), a effective rate of 100%, compared with the routine group had a cure rate of 91. 7%( 11 eyes ) , a effective rate of 100%, there were no statistically significant difference between the two groups (P>0. 05).?CONCLUSlON:Lacrimal fistula excision combined with double silicone intubation has a same effect with routine dacryocystorhinotomy in the treatment of chronic dacryocystitis with lacrimal fistula, but less invasive, no scar, less pain, and meet the patients' esthetic needs.

Objective To investigate the effect of remote ischemic preconditioning on myocardial infarction and the involved protective mechanisms. Methods Twenty-four male SD rats were randomly divided into four groups: ischemia-reperfusion (I/R) group, rote ischemic preconditioning (RIPC) group, remote ischemic preconditioning + ischemia-reperfusion (RIPC+I/R) group, and RIPC+AG490+I/R group. The blood samples and myocardial specimens were collected and prepared for tests. The related enzymes were detected and the size of myocardial infarction was measured. The cardiac cells were determined by electron microscopy and light microscopy. Results The size of myocardial infarct and myocardial enzymes were significantly reduced in RIPC+I/R group compared to those in I/R group (P < 0.05). The size of myocardial infarction and myocardial enzymes were significantly increased in AG490 group compared to those in RIPC+I/R group (P < 0.05), but were significantly reduced in AG490 group compared to those in I/R group (P < 0.05). Conclusions Remote ischemic preconditioning may be effective in cardioprotection. The JAK/STAT pathway is involved in the cardioprotection of remote ischemic preconditioning.
