Objective To investigate the efficacy of nicergoline combined with hyperbaric oxygen treatment on vascular cognitive impairment.Methods 120 patients with vascular cognitive impairment were randomly divided into 3 treatment groups:nicergoline,hyperbaric oxygen,and both treatment (n=40,each) for 8 weeks.Mini mental state examination (MMSE),Wechsler memory scale (WMS) and activities of daily living scale (ADL) were used as assessing items.The efficacy of treatment in each group was evaluated.Results There were no significant differences in clinical data among the three groups(x2=0.324,t=0.265 and 0.861,P=0.764,0.784 and 0.386).After 8 weeks of intervention,scores of MMSE,WMS and ADL were significantly improved in the combined treatment groups compared with pre-treatment (all P＜0.01),and the improvements were observed in nicergoline group (all P＜0.05),while only MMSE and ADL were improved in hyperbaric oxygen group (both P＜0.05).There were significant differences in scores of MMSE,WMS and ADL between combination therapy group and nicergoline group,hyperbaric oxygen group after treatment (all P＜0.05).But only MMSE had significant difference between niccrgoline group and hyperbaric oxygen group after treatment.No significant side effects were observed in the three groups.Conclusions Combination treatment of nicergline and hyperbaric oxygen has better efficacy on vascular cognitive impairment.It can markedly improve the activities of daily living and cognitive function without significant side effects,which is worthy of application in clinical medicine.

Objective To investigate the relationship of resting heart rate (RHR)and dyslipidemia in the elderly.Methods 3 919 cases of cerebrovascular disease risk factor screening in Renqiu permanent residents aged 60 -70 years were selected,excepted cases of atrial fibrillation and hyperthyreosis and received lipid -lowering and slowing the heart rate drugs as the research subjects,mean age 64(62,67)years,the rates of male and femal were 44.0% and 56.0% respectively.They underwent face -to -face health questionnaire,blood pressure and RHR meas-urement,anthropometric and laboratory tests.According to the RHR,they were divided into four groups:RHR1:<60 times/min,RHR2:>60 times/min and <70 times/min,RHR3:>70 times/min and <80 times/min,RHR4:>80 times/min.The effect of RHR on dyslipidemia was analyzed by multivariate logistic regression analysis.Results The high TC,TG,and the prevalence of high LDL -C increased gradually with heart rate,the differences were statisti-cally significant (all P <0.001).The prevalence low HDL -C and HDL -C levels had no obvious statistically differ-ences.TC,TG,and LDL -C and RHR were positively correlated.RHR1:<60 times/min was set as control group,the correction of gender,age,smoking,drinking,lack of physical activities,hypertension,diabetes,coronary heart disease, stroke or TIA,overweight,abdominal obesity,systolic pressure,diastolic blood pressure,fasting plasma glucose,insu-lin,uric acid,high TC in 60 -70 times/min,70 -80 times/min,and the risk of more than 80 times/min,respectively (OR =1.304,95%CI:0.983 -1.73),(OR =1.579,95%CI:1.195 -2.088),(OR =1.677,95%CI:1.258 -2.237).Conclusion The RHR and the prevalence of dyslipidemia is related,medical workers need to know the rela-tionship between RHR and dyslipidemia,increase the focus on RHR and intervention,in order to effectively control the occurrence of dyslipidemia and cardio -cerebrovascular disease,especially cholesterol heighten.

Objective To investigate the potential relationship between neck circumference and obesity related indexes and metabolic disorders associated with insulin resistance.Methods A random cluster sampling method was used to identify study population among the 4 412 60 -70 years old permanent residents in Renqiu region.Face to face health questionnaire,physical examination,laboratory tests were used.According to the gender group,the correlation between neck circumference and obesity related indexes and metabolic disorders associated with insulin resistance were analyzed.Results Comparing neck circumference and waist circumference,waist height ratio, and body mass index(BMI) of man and woman respondents,the differences were statistically significant.Neck circum-ference and waist circumference,waist height ratio,and BMI had positive correlation(male:r =0.752,0.695 and 0.761.W:r =0.707,0.655,0.721,all P <0.01).Increased trends of neck circumference,waist circumference,waist height ratio and BMI coincided with increased trend of thypertension,diabetes,hyperlipidemia and hyperinsulinemia and hyperlipidemia,and no gender differences.With the increase of the neck circumference,the incidence of above mentioned diseases also increased accordingly.Conclusion Neck circumference was associated with obesity related indexes and metabolic disorders associated with insulin resistance.Neck circumference measurement can be used as an effective indicator of central obesity,and had great significance for early prediction and prevention of metabolic disorders associated with clinical insulin resistance.

Objective To investigate the epidemiologic and behavioral characteristics of HIV among community population in Liangshan prefecture.Methods We collected social demographic,behavioral and serological information by means of the monitoring questionnaire and serological tests.Data was analyzed by using the chi-square test and logistic regression.Results From April to June of 2010 to 2015,14 092 cases of community population were selected as the study objects,with 267 cases diagnosed as HIV positive patients.The HIV positive rates were 3.24％,3.07％,1.17％,1.38％,1.42％ and 1.25％,respectively.We observed that when community population having the following characteristics as:living in Butuo country (OR=3.83),being males (OR=1.77),being Yi nationality (OR=4.40) being widowed (OR=28.57),with history of drug abuse (OR=3.71) or injecting drug use (PWID) (OR=4.92),or history of needle sharing among PWID (OR=8.53),were under higher risks for HIV infection.With histories as:having had secondary or above levels of schooling (OR=0.59),having protected sex with regular parmers (OR =0.21) and with non-regular partners (OR =0.46),they seemed to be somehow protected for getting HIV infection.Conclusion The positive HIV rates of HIV among community population in Dechang,Ningnan and Butuo varied from 0.10％ to 8.77％while the HIV transmission among general population remained challenging.
