Objective Investigate the effect of insomnia on cardiovascular disease factors and offer the experimental evidence for treating cardiovascular disease with traditional Chinese medicine tranquillization methods. Methods Sixteen Wistar rats were randomly divided into two groups named sleep deprivation ( SD ) group and normal control check( CC) group.Body weight and electrocardiogram were recorded and serum concentrations of melatonin ( MT) , endothelin-1 (ET-1), IL-6 and TNF-αwere tested before SD and 2 days, 5 days, 7 days after SD.Results Body weight decreased in SD group while increased in CC group.Compared with CC group, body weight of SD rats decreased significantly in 5 days and 7 days after SD( P <0.05) .Compared with CC group, TNF-αincreased significantly in 5 days (P <0.05).With the time, heart rate accelerate and QTc were prolonged, MT decreased while ET-1, IL6, TNF-αincreased significantly in 7 days after SD (P <0.05).Conclusion Long term insomnia would decrease body weight and MT, while increase heart rate, QTc, ET-1 and inflammatory factors, which increase cardiovascular disease factors.It provided the experimental evidence for the study on traditional Chinese medicine tranquillization methods in the treatment of cardiovascular disease.

Objective To analysis the constituents of urinary stones in southeast Chongqing district,and provide the percep-tion and treatment of urinary stones.Methods Retrospective analysis of 1 628 random urinary stones samples in southeast Chongqing district from 2008 to 2014.The chemical constituents of stones were analysis with the clinical data.Results Urinary stones were more often found in those 30 to 70 years old,especially in males.The upper system stones were frequently founded.The percentage of mixed stones and pure stones were similar,The constituents of stones were similar to male and female,the most com-mon component of the urinary stones are calcium oxalate,which were found in 82.9% of the stones,infection stones were found 1 9.2%,but only found in renal and ureteral stones,and also increase gradually.The most common component of urinary stones in Qianjiang and Pengshui district were calcium oxalate,the infection stones were frequently found in Youyang and Xiushan district. Conclusion Chemical composition analysis of urinary stones is simple,quick and accurate,it is very important in providing infor-mation to the etiology,treatment and prevention of urinary stones.

Objective To evaluate the relationship between insulin resistance and benign prostatic hyperplasia (BPH).Methods Totally 150 male patient from the Department of Geriatrics in Peking University Hospital were included in this study.Blood pressure,body weight,body height,body mass index (BMI) were measured and calculated.Biochemical analyses including serum fasting levels of insulin(FINS),glucose,total cholesterol,triglycerides,low-density lipoprotein cholesterol,high density lipoprotein cholesterol,and prostate-specific antigen (PSA) were performed.Total prostate volume (PV) were measured by ultrasound.Results PV and annual prostate growth rate were more increased in insulin resistance group(40 cases) compared with insulin sensitivity group(110 cases) (t=2.91,3.71 respectively,both P＜0.01).Along with the levels of FINS,HOMA-IR and PSA were increased,the prostate volume was enhanced (t=-3.02,-2.88,-2.84 respectively;all P ＜0.05).PV was positively correlated with insulin resistance,serum fasting insulin and PSA (r=0.16,0.16,0.35;all P＜0.05),while annual prostate growth rate was positively related with insulin resistance,serum fasting insulin,PSA and BMI (r =0.22,0.21,0.24,0.19 ; all P ＜ 0.05).Conclusions Insulin resistance and fasting insulin plays roles in the pathogenesis of prostatic hyperplasia.

BACKGROUND: As a primary clinical predictor of fracture risk, bone mineral density (BMD) is partly genetically determined. Osteoprotegerin (OPG) is one important candidate gene in the pathogenesis of osteoporosis. OBJECTIVE: To investigate the association between T245G polymorphisms in the OPG gene and BMD. METHODS: A total of 281 elderly men and postmenopausal women, 182 males and 99 females, who received routine examinations at Peking University People's Hospital between September 2008 and April 2010 were included in this study. T245G polymorphisms in the OPG gene was detected by polymerase chain reaction-restriction fragment length polymorphism together with DNA sequencing. The BMD of the lumbar spine, Ward's triangle, and forearrm was determined by dual energy X-ray absorptiometry. Clinical variables and biochemical measurements were collected simultaneously. The association between T245G polymorphisms and each detection index was analyzed using analysis of variance. RESULTS AND CONCLUSION: The distribution of T245G genotype (alleles T, G) had no difference in elderly men or postmenopausal women (P > 0.05). The GG genotype and TG genotype had higher lumbar spine BMD and TT genotype had lower lumbar spine BMD (P < 0.05). There was no difference in BMD of the Ward's triangle or forearm among different genotypes (P > 0.05). Association between T245G polymorphism and BMD was not found in postmenopausal women. These findings indicate that OPG gene is related to lumbar spine BMD in elderly men.

Objective To explore the relationship between serum 25-hydroxy vitamin D level and prostatic hyperplasia in elderly men.Methods Totally 95 male patients aged over 60 years were included.Blood pressure,body weight,body height,body mass index (BMI) were measured and calculated.Venous blood samples were obtained to determine fasting serum levels of 25-hydroxy vitamin D3 and blood glucose (FBG),total cholesterol (TC),triglycerides (TG),low-density lipoprotein cholesterol (LDL-C),high-density lipoprotein cholesterol (HDL-C),calcium and prostate specific antigen (PSA),total prostate volume(PV) and annual prostate growth rate were measured and calculated by ultrasound.Results The serum 25 (OH) D3 levels were varied from 12.1 nmol/L to 83.9 nmol/L,with an average of (35.5±15.2) nmol/L in elderly male patients.PV growth rate were significantly lower in elderly men with 25 (OH) D3 ＞ 50 nmol/L than in elderly men with 25 (OH) D3≤50nmol/L[(31.5± 6.0) mlvs.(39.9 ± 14.5) ml,(0.4± 0.2) ml/yvs.(0.5 ± 0.4) ml/y,P＜0.001 or 0.01].PV was negatively correlated with serum 25-hydroxy vitamin D3 level (r=-0.207,P＜0.05),and positively correlated with BMI and PSA (r=0.297,0.958,P＜0.05 or and P＜0.001).While annual prostate growth rate was positively correlated with BMI and PSA (r=0.316,0.464,P＜0.01 or ＜0.001),and positively correlated with serum 25-hydroxy vitamin D3 level,but the difference was not statistically significant (P＞0.05).Conclusions Low serum 25-hydroxy vitamin D3 level may play a role in the pathogenesis of prostatic hyperplasia.
