Objective To explore the relationship between serum thyroid-stimulating hormone ( TSH) and dyslipidemia. Methods A total of 1 512 inhabitants in Zhaiji community of Guiyang urban areas were investigated from November 2009 to February 2010 by adopting stratified cluster sampling method, and 1 428 subjects were included in the present study. All subjects were asked to fulfill the questionnaires and to pass a physical examination. The vein blood samples were taken for determination of serum TSH, fasting plasma glucose (FPG), insulin, as well as blood lipid levels. Results Triglyceride ( TG ) , total cholesterol, high density lipoprotein cholesterol, and low density lipoprotein cholesterol levels were significantly increased in woman with subclinical hypothyroidism(SCH) compared to those with euthyroid(all P<0. 05). However, there was no significant difference in man between two groups(P>0. 05). The incidences of hypertriglyceridemia in the euthyroid group from quartile 1 toquartile4ofTSHwere33.3%,35.5%,39.7%,and44.0% respectively(P<0.05). SerumTGlevelwas increased with TSH in woman and total subjects after adjustment for age, sex, body mass index ( BMI) , waist-hip ratio (WHR), and homeostasis model assessment for insulin resistance index(HOMA-IR, P<0. 05). Serum TSH levels in the total sample were positively associated with TG after adjustment for age, sex, BMI, WHR, and HOMA-IR (β=0. 088,P<0. 05). Conclusion Higher serum TSH levels even within normal range seems to be a risk factor of dyslipidemia.

A total of 1512 adult inhabitants were randomly recruited in Zhaiji district of Guiyang city in September2009.The levels of triglyceride (TG),systolic blood pressure,diastolic blood pressure,and the prevalences of abdominal obesity and hypertension increased significantly in the subclinical hypothyroidism group conpared to the euthyroid group (P＜0.05).The prevalences of high TG,low high density lipoprotein-cholesterol,and metabolic syndrome (MS) in the subgroup Ⅳ were higher than the subgroup Ⅰ (P＜0.05).Correlation analysis revealed that TSH was positively related to TG (P＜0.05).Logistic regression demonstrated that TSH was a risk factor for MS.Either in the euthyroid or total subjects serum TSH levels in the MS group were significantly higher than those in non-MS group(P＜0.05).

Objective To explore the association of serum uric acid (UA) with metabolic syndrome (MS) and its components.Methods A total of 1 512 inhabitants aged 20 years old and above in Zhaiji community of Guiyang urban areas were investigated from November 2009 to February 2010 by adopting stratified cluster sampling method (634 males and 878 females).All subjects were asked to fulfill the questionnaires and to measure the height,weight,waist circumstance (WC),and blood pressure ; and to undertake oral glucose tolerance test.Venous blood samples were drawn to measure UA,fasting plasma glucose,2 h postprandial plasma glucose,triglyceride (TG),total cholesterol,high density lipoprotein cholesterol,low density lipoprotein cholesterol,and fasting insulin.Results (1) Age,body mass index (BMI),WC,TG,and blood pressure,and homeostasis model assessment of insulin resistance (HOMA-IR) increased with UA (all P＜0.05).(2) UA was positively associated with the risk of MS (P＜ 0.05).After adjusting for age,sex,BMI,waist-to-hip ratio (WHR),and HOMA-IR,the risk of MS in individuals with the highest uric acid quartiles was significantly increased compared to those with the lowest quartile (OR =2.86,95 ％ CI 1.70-4.84,P＜0.05),and this finding was especially evident in females (OR=2.80,95％ CI 1.51-5.17,P＜0.05).(3) UA was strongly related to WC (OR =1.76,95％ CI0.95-3.27,P＜0.05),blood pressure (OR =1.66,95 ％ CI 1.13-2.43,P＜0.05),and TG (OR =2.80,95％ CI 1.97-3.96,P＜0.05) after adjustment for age,sex,BMI,WHR,and HOMA-IR.Conclusion The prevalence of MS increased with UA.Higher UA level may be an independent risk factor for MS.

_ Objective_ To examine the association between sleep duration, TV watching time, and the incidence of metabolic syndrome in people aged 40 or older in Guiyang city. Methods Data were obtained at the baseline examination ofThe epidemiological study on the risk of cancer in patients with type 2 diabetes in China in 2011. Follow-up study was conducted in 2014 to 2015. A total of 4 392(female 2 987, male 1 405)were included in the analysis. Results According to diagnostic criteria of International Diabetes Federation(IDF)in 2005, 1 035(812 women, 223 men) of the cohort developed metabolic syndrome during an average follow up for 3 years. Sleep duration was classified as≤7 h/d, 7-9 h/d,≥9 h/d, the incidence of metabolic syndrome was 24. 46%, 22. 43%, 23. 65%, respectively. TV watching time was divided into 0-1 h/d, 1. 1-2 h/d, 2. 1-4 h/d,>4 h/d, the incidence rates were 20. 67%, 22. 91%, 24. 61%, 25. 76%, respectively. In multivariate logistics regression analysis, compared with 0-1 h/d, the RR values of women with TV watching time during 1. 1-2 h/d, 2. 1-4 h/d,>4 h/d were 1. 098(95%CI 0. 789-1. 528), 141. 6(95% CI 1. 052-1. 906), 1. 559(95% CI 1. 090-2. 233), respectively. Conclusion The standardized incidence rate of metabolic syndrome in the general population was 23. 12%, the crude rate was 23. 57%. The incidence of metabolic syndrome was unrelated to the sleep duration and TV watching time as a whole or in men. TV watching time more than 2 hours a day may increase the risk of the metabolic syndrome in women.

Objective To investigate the relationship between changes of ankle brachial index (ABI) and adverse cardiovascular events. Methods Baseline survey was conducted in 4 160 forty-year-old or older citizens living in Yunyan District of Guiyang City from May to August of 2011, which was in the way of cluster sampling to obtain their ABI and to collect information related to physical and blood biochemical examination and disease history. These citizens were conducted a follow-up survey for (39.29±1.47) months from July to December of 2014. Based on the change of ABI (ΔABI) from initial survey to follow-up survey, participants were subsequently divided into three groups: ΔABI>0.15 group,-0.15≤ΔABI≤0.15 group and ΔABI<-0.15 group. The adverse cardiovascular events during follow-up survey were compared between three groups. The risk factors affecting the adverse cardiovascular events were analyzed. Results Follow-up surveys were completed in 3 220 citizens in 3 years. The follow-up rate was 77.4%. Eighty-two new cases (2.5%) of adverse cardiovascular events were found in 3 220 cases in follow-up. The incidence rates of adverse cardiovascular events were higher inΔABI<-0.15 group compared with those of-0.15≤ΔABI≤0.15 group (8.3%vs. 2.4%, P<0.016 7). Logistic regression analysis indicated that age, hypertension history, and ΔABI<-0.15 were risk factors for adverse cardiovascular events. Exercise was the protective factor for adverse cardiovascular events. Conclusion Subjects withΔABI<-0.15 are at high risk for adverse cardiovascular events. The ΔABI can be used as a means of monitoring of adverse cardiovascular event, which provides certain forecast value for determining the possibility of adverse cardiovascular event.

Objective To investigate the relationship between brachial ankle pulse wave velocity and the incidence of cardio-cerebral events in people aged over 40. Methods Cluster sampling method was used to prospectively study 4 380 residents aged over 40 in Guiyang City District from May to August in 2011. Data of ba-PWV were collected. The follow-up examination was conducted from July to November of 2014. According to ba-PWV values, participants were divided into three groups:<14 m/s (control, n=1 039) group, 14-17.9 m/s group (n=1 393) and≥18 m/s group (n=809). Multi-factor Logistic regression model was used to analyze the relationship between ba-PWV values and risk factors of cardio-cerebral events. Results After three-year follow-up, a total of 3 241 participants were included in the final analysis. The cardio-cerebral events were identified in 63 (2.0%) cases, which were 0.6%, 2.2%and 3.2%in control group, 14-17.9 m/s group and≥18 m/s group. The value of ba-PWV increased significantly in those two groups compared with that of normal group. Logistic regression analysis showed that the incidence rates of cardiovascular and cerebralvascular events in 14-17.9 m/s group and≥18 m/s group were 2.777 (1.123-6.864) and 2.786 (1.032-7.526) times of control group after adjusting age, gender, systolic blood pressure, risk factors of diabetes, hypertension and blood lipids. Conclusion There is higher incidence rate of cardio-cerebral events in people aged over 40 in higher ba-PWV group. The value of Ba-PWV can be used to predict the occurrence of cardio-cerebral events.

OBJECTIVETo explore the therapeutic effects of internal fixation with Herbert screws for the treatment of Pipkin type I and type II femoral head fractures.

METHODSFrom January 2008 to December 2012, 23 patients with Pipkin type I and type II femoral head fractures were treated with open reduction and internal fixation by Herbert screws through Kocher-Langenbeck approach. Twenty-three patients (aged 18 to 52 years with a mean of 35.5 years, including 18 males and 5 females patients, 8 left hips and 15 right hips) with femoral head fractures and posterior hip dislocation. The fracture was classified according to Pipkin classification based on the radiographic findings, 5 patients had type I and 18 had type II fractures. The duration time from admission to the operation ranged from 6 to 72 h (averaged 32 h). The clinical and radiographic outcomes of the patients were measured using Thompson-Epstein scoring scale. The Harris hip score(HHS) was used to evaluate and compare hip functions at the latest follow-up between affected and healthy sides.

RESULTSAll the patients were followed up, and the duration ranged from 20 to 48 months (averaged 30 months). According to Thompson-Epstein system, 12 patients got an excellent result, 6 good, 4 fair and 1 poor. The average HHS at the finial follow-up was 87.80 ± 8.46 (ranged from 66 to 95), which is similar to that in the healthy side 90.10 ± 6.35 (ranged from 72 to 98) (t = 1.044, P = 0.302). The complications such as deep infection, and deep vein thrombosis were not found. At the 3rd year during follow-up,4 patients had avascular necrosis of femoral head. At the 1st year of follow-up, 1 patient had hip pain after walking,screws loosening and shift after trauma,and serious complications of traumatic arthritis. All the 5 patients were treated with total hip arthroplasties.

CONCLUSIONThe treatment of internal fixation with Herbert screws through the Kocher-Langenbeck approach is effective for Pipkin type I and type II femoral head fracture. The method is reliable and valuable for recommendation. However, such fracture may have avascular necrosis of femoral head and complication of traumatic arthritis, which should be observed carefully in clinic with preparation of the prevention and treatment measures.
