Objective To explore the effect of antidepressant adjuvant treatment for chronic prostatitis (CP),and to find an effective treatment for the clinical therapy of CP.Methods 88 patients with CP were randomly divided into two groups,the control group 41 patients were treated with the antibacterials moxifloxacin,the treatment group 47 patients were treated with the moxiiloxacin treatment and paroxetine adjuvant therapy.The clinical symptoms,life quality (QOL) and Zung depression scale score of the two groups were evaluated and compared.Results After four weeks of treatment,voiding difficulty endless,urinary urgency,perineal discomfort symptoms of the treatment group were improved significantly compared with the control group (x2 =23.563,18.348,15.874,all P ＜ 0.05).After four weeks of treatment,QOL,Zung depression scale scores the treatment group were more significant decline than before treatment and the control group after treatment (t =0.554,0.615,0.382,0.336,all P ＜ 0.05).Conclusion Antidepressant adjuvant therapy improves the psychiatric symptoms of CP patients,which can effectively improve the clinical efficacy of antibiotic therapy of CP.

Objective To explore the diagnosis and treatment of unsuspected gallbladder cancer (UGC)related with laparoscopic cholecystectomy(LC).Methods From January 1995 to Dece m ber 2008,4520 cases of LC were performed,UGC waS discovered in 15 cases.Clinical data of the 15 cases were analyzed retrospectively.Results Among the 15 cases of UGC,7 were discovered intraoperatively,and 8 were diagnosed postoperatively.Postoperative pathological examination showed Nevin stage I in 4 cases,stage Ⅱin 7 cases,stage Ⅲ in 3 cases,stage Ⅳ in 1 case.LC was carried out in the patients of Nevin stage I.Radical resection of gallbladder cancer was performed on the patients at stage Ⅱ and stage Ⅲ.One patient at stage Ⅳ received extended radical resection.The patients were followed up from 6 months to 5 years,during the period 3 cases were died and 12 cases were still alive,the 5-year survival rate wag 80.0%.Conclusions Most of LC-related UGC cases are early cancer.Frozen section examination should be performed for high-risk groups and suspicious persons,which contributes to the discovery of UGC.LC can achieve the radical purpose of Nevin stage I patients,Nevin stage Ⅱ-Ⅳ requires open radical operation.

Objective To investigate the relationship between serum leptin levels and insulin resistance(IR)in obesity and hypertensive patients and their role on the occurrence of hypertension or/and obesity.Methods Serum glucose,insulin,total cholesterol(TC),triglycerides(TG),HDL－ C,LDL－ C,uricacid(Ur),insulin sensitivity index(ISI),urinary albumin excretion(UAE)and serum leptin concentrations were determined in 66 men with essential hypertension and 67 male normotensives.The correlations between leptin and IR,and they and body mass index (BMI),blood pressure and other parameters were analyzed.Results Serum leptin levels were signifcantly higher in hypertensive and obesity subjects than in normotensive and nonobesity ones.ISI of nonobesity was higher than obesity in normotensive group,but both obesity and nonobesity ISI was higher in normotensive group than in hypertensive one .No significant change in obesity and nonobesity was found for the decreased levels and ISI(r=－ 0.51,P<0.01 and r="－" 0.38,P< 0.05,respectively ) and the most singificant factors that affected serum leptin levels were BMI,waist hip ratio and ISI and the factors that affected ISI in order of importance were BMI,SBP,DBP,TG,Ur and leptin in obesity subjects of both hypertensive and ISI in above mentioned patients.The multiple regression analysis indicated that BMI was closely correlated with leptin,ISI and TG in obesity patients of both hypertensive and normotensive groups. Conclusion The increase in serum leptin levels in obesity is highly correlated with ISI and is correlated with lipid metabolism.leptin resisitance may has a indirect action in occrrence of hypertension and the correlation with IR remain to be sutdied.

The results observed in normal weight group (81 subjects), simple obese group (140 subjects) and hyperglycemic obese group (97 subjects) showed that there was a significantly positive correlation between ? cell function and endothelium-dependent vasodilation function (EDV) in hyperglycemic obese group (r=0.52, P

Transient ischemic attack(TIA) is one frequent type of acute ischemic cerebral vascular disease.Much advancement has been made in the definition,aetiology,diagnosis and therapy of TIA in recent years.Carotid endarterectomy and carotid angioplasty and stenting is the latest therapy of carotid artery stenosis.

Objective To explore the regulating mechanism of the astrocytes on the expression of ?-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid receptors(AMPARs) subunit in epileptogenesis. Methods The astrocytic conditional medium(ACM) was collected after being stimulated by glutamate,and then ACM was added to the cultured hippocampal neurons.The expression changes of neuronal GluR2 and protein interacting with C-kinase-1(PICK1) mRNA were detected by RT-PCR. Results In the cultured hippocampal neurons,the GluR2 mRNA expression was significantly decreased at the 2nd,8(th),and 12(th) hours after the administration of ACM compared with that in the control group(P

Objective To explore the effect of insulin-like growth factor-1(IGF-1) on the growth of muscle-derived stem cells(MDSCs). Methods MDSCs were isolated from the hindlimb muscle of new born mice through serial preplates.DMEM with 2% fetal bovine serum was used to induce MDSCs to differentiate into skeletal muscle lineage.The expression of stem cell marker Sca-1 or skeletal muscle cell marker ?-sarcomeric actin was examined by immunocytochemistry SP method.MTT colorimetric microassay was conducted to determine the effect of IGF-1 on MDSCs proliferation.The relationship between functioning and culture time and the relationship between functioning and IGF-1 concentration were studied. Results MDSCs were successfully isolated from the hindlimb of neonatal mice.Over 90% of the MDSCs showed Sca-1 positive immunoreactivity.MDSCs could give rise to ?-sarcomeric actin positive myotubes in differentiation cultures.The proliferative effect of IGF-1 on MDSCs increased gradu ally with prolonged culture time.The elevation of IGF-1 concentration also increased the proliferative effect until it came to a saturation point.Conclusion IGF-1 can promote the proliferation of in vitro cultured MDSCs.

Objective To explore the clinical role of transbranchial needle aspiration(TBNA) in the lymph node staging of lung cancer.Methods To forty-six cases of lung cancer with suspected lymph node metastasis by chest CT scan,the TBNA was performed before operation.The cytological results were compared with post-operative pathology.Results In total 94 groups mediastinal nodes,fifty-nine groups were positive by TBNA,sixty-seven groups were diagnosed lymph node metastasis by pathology,the positive accuracy was 88% with the total coincidence rate of 82.6% by cytolagical typing.The overall accurate rate of c-N by TBNA was 86.9%(40/46) compared with p-N.Conclusion TBNA for lymph node staging and pathologic typing of lung cancer is a safe,simple and economic method with high accuracy and high clinical application value.

Objective To explore how the self-stigma of mental illness influence self-esteem and social support.Methods 109 mental illness from Jinan,Tianjin and Harbin were asked to finish a questionnaire integrated from the ISMI,SES,PSSS,and the data were calculated by SPSS18.0.Results According to the regression of self-stigma and its five attributes on the self-esteem,self-stigma was negative correlated with self-esteem,with self-alienated was the most significant attribute,the next being the public relations avoidance and the incompetent sensation,while the flight from reality and the discrimination experience were not remarkable attributes (Y =4.585-0.722x(F=59.508,P＜0.001) and Y =4.470-0.388x1 +0.813x2-0.198x3-0.064x4-0.192x5 (F=16.609,P＜ 0.001)).According to the regression of self-stigma and its five attributes on social support,self-stigma was negatively correlated with social support,self-alienated was the most remarkable attribute,and the next were the public relations avoidance and the discrimination experience,while the flight from reality and the incompetent sensation were not remarkable to the social support.(Y =3.710-0.354x(F=9.116,P＜0.01) ; Y =3.474-0.391x1 +0.102x2+ 0.301x3+0.047x4-0.301x5 (F=5.695,P＜0.001)).Conclusion The self-stigma of mental illness has negative influence on the self-esteem and social support.
