Objective To investigate the levels of blood pressure, blood lipid, blood glucose, body mass index (BMI) as well as the epidemiological characteristics of dyslipidemia, hyperglycemia, hypertension and metabolic syndrome of Hangzhou citizens. Methods A total of 28 990 citizens in Hangzhou city who underwent health checkup were recruited in this study, including 10 179 males and 18 811 females. The average age of subjects was 65.05 years. Subjects were asked to complete questionnaires regarding personal characteristics. The physical examination emphasized measurement of height, waist and blood pressure. Blood samples were collected and subjected to serum glucose, TC, HDL-C, LDL-C and TG measurements. The values of the examinations was described as xˉ± s . The ratios were compared with chi-square test. The trend analysis was conducted by linear correlation test. Results The prevalence of hypertension and metabolic syndrome was 17.1% and 11.2% respectively. And the prevalence of overweight/obesity and hyperglycemia was 36.3%,8.1%,16.4%respectively. It was indicated that the men had higher prevalence of hyperglycemia, hypertension, metabolic syndrome and overweight compared with women. However, as to the dyslipidemia, men and women were totally different. Women were more prone to suffer from hypercholesterolemia and elevation of low-density lipoprotein cholesterol. Men were apt to suffer from hypertriglyceridemia and reduction of high-density lipoprotein cholesterol. Divided the subjects by age into three groups, it was suggested that the rates of dyslipidemia, hyperglycemia, hypertension and overweight/obesity increased along with the increment of age in women. Although the rates of metabolic disorders were higher in the group of men, the trend of increase with age was not as significant as in women. It could be seen in men that dyslipidemia and overweight/obesity were reduced with the increase of age. Conclusion The metabolic disorders in Hangzhou citizens showed their own characteristics. It is suggested that multiple strategies targeting at different sexes and age-groups should be formulated to prevent and control the occurrence of metabolic diseases.

Objective In order to provide clinical evidence of reducing postoperative complications of procedure for prolapse and hemorrhoids and observe the effects of constipation on postoperative complications of procedure for prolapse and hemorrhoids.Methods One hundred and sixty cases of hemorrhoid were divided into two groups according to whether suffering from constipation:there were eihgty cases who were suffered from constipation in the experimental group and eighty cases who were not suffered from constipation in the control group.All patients' postoperative bleeding,anal edema,stool impaction and satisfaction were observed within 30 days and these data were compared and analysed by using SPSS 13.0 software.Results In the experimental group,the postoperative bleeding incidence was 37.5 ％ (30/80),the anal edema incidence was 31.3 ％ (25/80),the stool impaction inci dence was 8.6％ (7/80),and the patients' satisfaction rate was 88.6％ (71/80).In the control group,the postoperative bleeding incidence was 18.6％ (15/80),the anal edema's incidence was 15.0％ (12/80),the stool impaction incidence was 1.3％ (1/80),and the patients' satisfaction rate was 97.5％ (78/80).All the indexes above were different statistically in the two groups (P ＜ 0.05).Conclusion constipation could increase complications and reduce the degree of satisfaction after procedure for prolapse and hemorrhoids.

Objective To observe the changes of serum potassium concentration in rectal cancer patients from the admission to before the operation,to provide clinical evidence for preventing serum potassium disorder during and after their operation.Methods Monitoring of the changes of serum potassium concentration of 40 cases of rectal cancer patients according to three time points including the first day of admission,before taking of cathartics and the morning before operation.They were divided into different groups according to their age(young,middle age and elderly group),gender(male and female group),diet(normal,decreased slightly and serious decline group) and course(long,middle and short course group) of disease.The serum potassium concentration was observed between each time point of each group and SPSS13.0 statistical software was used to analyze the changes above.Results The mean of all patients' serum potassium concentration was (4.09 ± 0.62) mmol/L on the first day of admission,was (3.83 ± 0.46) mmoL/L before taking of cathartics that was decreased compared to the former and there was significant difference (P ＜ 0.01),it was (3.36 ±0.40) mmol/L on the morning of operation and had significant difference with the above two groups (P ＜ 0.01).It hadn't significant difference between different gender and age groups at different time points (P ＞ 0.05) except between the young group and the elderly group in the morning of the operation (P ＜ 0.05).There were statistically significant differences between the different diet condition and different course at anytime point (P ＜ 0.01).Conclusions The rectal cancer patients were possiblely in hypokalemia before operation,the causes might be relative to the long course of disease,the decreased diet,the aged and infirm,the diet structure change after admission and taking cathartics cleaning intestinal tract.

Objective: To understand social anxiety and relevant factors among graduate students under the normalization stage of COVID-19 epidemic prevention and control. Methods: Using convenience sampling method, an online questionnaire survey on graduate students from 5 universities in Jiangsu Province was conducted. Measurements used in the survey includes General Self Efficacy Scale (GSES), General Alienation Scale (GAS), Interaction Anxiousness Scale (IAS) and self made survey for basic information and household living conditions. Results: The overall score of graduate students self efficacy was (2.58±0.50). Average score was (30.68±6.22) for alienation, and (47.55±8.77) for interaction anxiety, with detection rate of social anxiety being 43.96%. Increased dependence on smartphones and electronic devices ( OR=1.86, 95%CI =1.32-2.61) and high alienation score (medium level: OR=2.06, 95%CI =1.45-2.92; high level: OR=5.19, 95%CI =1.00-27.00) were positively correlated with social anxiety. Increased communication with friends ( OR=0.65, 95%CI =0.47-0.90 and high self efficacy (medium level: OR= 0.37 , 95%CI =0.21-0.66; high level: OR=0.15, 95%CI =0.08-0.30) were negatively correlated with social anxiety. Conclusion At the normalization stage of COVID-19 epidemic prevention and control, social anxiety of graduate students is one of the mental health issues which need further attention. Participation in peer support helps prevent social anxiety through developing self efficacy, alleviating individual alienation, and reducing dependence on electronic devices among graduate students.
