Objective To understand the blood lipid levels and abnormal conditions of the senior citizens aged over 65 in Shenz-hen city and provide a scientific basis for prevention of dyslipidemia.Furthermore,to investigate the influence of dyslipidemia on the result of hemoglobin(Hb).Methods Through random investigation of 252 samples aged over 65 in Shenzhen on their fasting serum TC,TG,HDL-C,LDL-C and Hb in peripheral venous blood and analyze current situation of dyslipidemia.By comparing the groups with dyslipidemia (A,B,C,D group)and group with normal blood lipid (E group),investigation on the influence of dyslipidemia on Hb was conducted.Results The total prevalence of dyslipidemia was 48.02%,TG,TC,LDL-C,HDL-C prevalence was 26.19%, 32.14%,25.79%,17.86% respectively.The average value of TG,TC,LDL-C,HDL-C respectively was(1.53 ±0.66),(4.79 ± 0.90),(2.96±0.77),(1.28±0.26)mmol/L.The prevalence and the difference of average level on TG between male and female was significant in statistics(P <0.01).There had been statistical differences of Hb among groups A,B and group E(P <0.05 ). Conclusion The total prevalence of dyslipidemia of people over the age of 65 in Shenzhen is higher than average,especially in TC. There is interference on Hb when TG,TC is abnormal.Therefore,emphasis should be laid clinically and related rectification must be carried out to ensure the accuracy of Hb.

Objective:To explore the application of Allostatic Load (AL) in evaluation the effect of management for patients with type 2 diabetes.Methods:According to the control objectives of each indicator in the Guidelines for the Prevention and Treatment of Type 2 Diabetes in China, the P75 and P80 of the subjects before intervention, AL was calculated, which were AL1-1, AL1-2 and AL1-3 respectively. On the basis of the above three indicators, the number of complications was taken as the numerical sum to obtain AL2-1, AL2-2 and AL2-3. Study participants were from a one-year randomized controlled intervention trial in patients with type 2 diabetes. Patients in the control group were treated with the integrated diabetes management mode used bg the tier-three medical institutions, while the intervention group added the intervention based on " Your Doctor" App on the basis of the above strategy. The changes of 6 types of AL and HbA 1C in the two groups before and after intervention were compared. Two groups of patients were treated with propensity score matching method to ensure the balanced distribution of covariates between groups. Multiple regression analysis was used to explore the factors influencing the effect of AL intervention. Two independent samples t-test, paired t-test and chi-square test were used to analyze the efficacy of the intervention. Results:After propensity score matching, the control group and the intervention group each included 483 patients. Among the six types of AL, the score of AL2-1 was the highest, while the score of AL1-3 was the lowest. Compared with baseline, all other indicators in the two groups decreased after intervention except ALL-3 in control group ( P<0.05).Patients who were residing in rural areas, having less co-habitants and more diabetic complications, and lower annual household income, shown higher AL ( P<0.05). The number of complications and the situation of urban or rural areas were the factors influencing the effect of AL intervention. Conclusions:More research is needed on AL as an early evaluation index of the effect of comprehensive management of diabetes.

Objective:To evaluate the impact of health education intervention on promoting rural residents to join new rural cooperative medical system(NCMS)and their intention of joining NCMS based on Health Belief Model in project areas in Henan and Jilin Provinces.Methods:Quasi-experiment study was used to evaluate intervention impact.Following the evidence-based approach,according to needs assessment,a half-year health education intervention was implemented among farmers in the experimental counties in Henan and Jilin Provinces respectively.A questionnaire survey was conducted among farmers in intervention and control counties before and after intervention,and intervention impact was evaluated by comparing the indicators' changes in intervention and control counties.Results:After health education intervention,the knowledge level of farmers in two intervention counties increased by 29.0% and 37.8% respectively,their scores of perceived threatens of health risk and perceived barriers of joining NCMS among the respondents were decreased.Meanwhile,their score of perceived benefit of joining NCMS were increased,and the rate of willingness to join NCMS increased remarkably in both intervention counties.Conclusion:Health education was effective and helpful in increasing farmer's knowledge,understanding and cognitive level of NCMS,and it should play an important role for the sustainable development of NCMS.

Objective To investigate the clinical effect of nicorandil for treatment of patients with acute respiratory distress syndrome (ARDS).Methods A prospective randomized controlled trial was conducted. A total of 40 cases of patients with ARDS admitted to Department of Critical Care Medicine of Guizhou Provincial People's Hospital from October 2012 to October 2014 were enrolled, and they were randomly divided into two groups, 20 cases in each group. The two groups were treated with routine western medicine after admission. On this basis, the observation group was given nicorandil 10 mg, while the control group was given warm boiled water 10 mL, through gastric tubes 3 times a day, the therapeutic course being consecutive 5 days in both groups. The length of stay in intensive care unit (ICU), duration of mechanical ventilation after treatment, oxygenation index (OI), alveolo-arterial oxygen partial pressure difference (PA-aO2), positive end-expiratory pressure (PEEP), acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) score, Glasgow coma score (GCS) before and after treatment, the predicted death rate (PDR) and 28-day mortality were compared between the two groups. The predicitive factors for 28-day mortality were screened by binary logistic analysis.Results The length of stay in ICU and duration of mechanical ventilation of control group were longer than those of observation group, but the difference was not statistically significant [ICU length of stay (day): 14.55±12.71 vs. 9.15±6.00, duration of mechanical ventilation (day): 13.25±12.27 vs. 7.75±5.32, bothP > 0.05]. After treatment, the GCS was higher than that before treatment in control group and observation group (11.95±3.98 vs. 10.75±4.89, 12.95±3.67 vs. 12.20±4.56), while APACHE Ⅱ score, PDR and PEEP were all lower than those before treatment [APACHE Ⅱ: 21.05±8.58 vs. 24.90±5.63, 18.70±11.21 vs. 26.65±7.67; PDR: (47.71±29.49)% vs. (61.00±23.29)%, (36.79±18.49)% vs. (56.12±18.16)%; PEEP (cmH2O, 1 cmH2O = 0.098 kPa): 4.40±3.14 vs. 5.75±2.59, 3.80±2.55 vs. 7.55±3.32], but there were no statistically significant differences between the two groups before and after treatment (allP > 0.05). After treatment, the OI was significantly higher and the PA-aO2 was significantly lower than those before treatment in the two groups, and the degrees of improvement of the observation group were more remarkable than those of the control group [OI (mmHg, 1 mmHg = 0.133 kPa): 224.72±85.12 vs. 141.37±45.82, PA-aO2 (mmHg): 132.60±46.64 vs. 204.30±121.2, bothP < 0.05]. The 28-day mortality of observation group was lower than that of control group, but no statistically significant difference was seen [15% (3/20) vs. 25% (5/20),χ2 = 0.156,P > 0.05). Binary logistic regression analyses showed that the PA-aO2 [odds ratio (OR) = 0.958,P = 0.013, 95% confidence interval (95%CI) = 0.927 - 0.991], APACHE Ⅱ score (OR = 0.882,P = 0.010, 95CI = 0.803 - 0.970), GCS (OR = 1.399, P = 0.004, 95%CI = 1.111 - 1.761) and PDR (OR = 0.907,P = 0.002, 95%CI = 0.853 - 0.965) after treatment were the independent predictors of 28-day mortality.Conclusion Nicorandil can significantly improve oxygenation, but cannot reduce 28-day mortality in patients with ARDS.
