Objective To observe the characteristics of glycemic excursion and to evaluate the therapeutic effects on blood glucose in new dignosed type 2 diabetes mellitus after being given continuous subcutaneous insulin infusion(CS Ⅱ).Methods Thirty-eight new dignosed type 2 diabetes mellitus patients were randomly divided into group CS Ⅱ(n=18) and group many-times subcutaneous insulin infusion(MS Ⅱ,n=20).The blood glucose lasted for three days were monitored by continuous glucose monitoring system(CGMS).Results The abnormal glucose metabolism in two groups were markedly released after two weeks treatment,the mean blood glycemic(MBG),mean amphtude of glycemic excursions(MAGE),means of daily differences(MODD) and the percentage of blood glucose beyond 7.8 mmol/L and 11.1 mmol/L after therapy were all significantly decreased compared with those of before therapy (P＜0.001);the average levels of blood glucose before and after diet were decreased obviously as well(P＜0.05,P＜0.01).All index in group CS Ⅱ were lower than that of group MS Ⅱ (P＜0.01,P＜0.001).Conclusion Continuous glucose monitoring system can assess the changes characteristics of blood glucose effectively,continuous subcutaneous insulin infusion was an effective means of controlling blood glucose.

A total of 105 patients with ketosis-onset diabetes were divided into four groups (A+B-,A + B +,A - B -,A - B +) based on the results of islet-associated autoantibodies (A +,A - ) and β-cell function (B +,B - ).Nearly 94％ patients in the A -B + group and 1/10 patients in the A - B - group were non-insulin dependent.While in the A + B - and A + B + groups,the detection rates of subsequent non-insulin dependency were 20％ and 58％,respectively.Among the four groups,patients in the A - B + groups had a lower level of IL-6 and a higher level of TNF-α. Patients in the A + B - and A + B + groups had a higher level of IL-18.Our study indicates that patients with ketosis-onset diabetes may present different clinical characteristics. Evaluate the islet-associated autoantibodies and pancreatic β-cell function may be helpful to the clinical diagnostic and therapeutic strategies in diabetes.

Background:In recent years, the incidence of ulcerative colitis (UC) has increased year by year in China, and the number of elderly patients with UC is growing significantly.However, the difference in clinical characteristics between elderly and non-elderly UC patients was not fully clarified.Aims:To investigate the difference in clinical characteristics between elderly and non-elderly UC patients.Methods:A total of 163 UC patients admitted from Jan.2012 to Jun.2015 at the Affiliated Jiangyin Hospital of Southeast University Medical College were retrospectively recruited and divided into elderly group (no less than 60-year-old, n=32) and non-elderly group (less than 60-year-old, n=131) according to the age of onset.The clinical data were collected, and the general conditions, clinical manifestations and extent of the disease were compared between the two groups.Results:There were no significant differences in gender, family history of inflammatory bowel disease, history of smoking and appendectomy between elderly and non-elderly groups (P>0.05).Hematochezia and mucous bloody stool were less prevalent in elderly group than in non-elderly group (P<0.05), and the prevalence of abdominal pain, diarrhea and weight loss was comparable between the two groups (P>0.05).More extraintestinal manifestations were seen in non-elderly group, but the difference was not statistically significant (P>0.05).Lesions in elderly group mainly located in left hemicolon, while pancolitis was predominant in non-elderly group (P<0.05).Conclusions:In elderly patients with UC, hematochezia and mucous bloody stool are not frequently seen, and the disease is not extensive and mainly located in left hemicolon.

Objective To investigate the predisposing locations of active hemorrhage in patients with esophageal variceal bleeding. Methods Data of 823 patients with acute esophageal and gastric variceal hemorrhage receiving emergency gastroscopy diagnosed from January 2003 to December 2013 were retrospectively studied. The location and site of active hemorrhage or stigmata were analyzed and its relationship with active hemorrhage was discussed. Results A total of 372(45. 2%,372/823) patients with active bleeding and stigmata were found under emergency endoscopy. Among 372 patients, 190 got accurate hemorrhage and stigmata location and site description. Bleeding or stigmata in 58(30. 5%) patients was 28-32 cm from incisor in group A, and that in 132 (69. 5%) patients was more than 35 cm in group B ( χ2＝57. 642, P＜0. 000 1). In 190 cases, the proportion of bleeding or stigmata at 3:00 point was the highest (37%,70/132), followed by those at 12:00 point(30%,58/132),6:00 point(24%,45/132),and 9:00 point (9%,17/132). The change trend of the percentage of each point in group A and group B was the same as that in all cases. The percentage of almost all points in group B was significantly higher than that in group A except that at 9:00 point ( P＜0. 000 1).Conclusion Esophageal variceal bleeding in cirrhosis is more common at 3:00 point, 6:00 point and 12:00 point of esophagus, and the high risk area is 35 cm below the incisors.

Objective To investigate the association between serum estradiol levels and macrovascular complication of atherosclerosis in mid-aged and elderly male patients with type 2 diabetes mellitus(T2DM).Methods One hundred and twenty nine male diabetic patients aged over 45 years were recruited in this study.Serum estriol(E2), testosterone(T)and lipid levels were detected using chemiluminescent immunoassay.Carotid ultrasonography was taken to evaluate macrovascular complication of atherosclerosis.The demographic characteristics, clinical features including duration of diabetes and prevalence of carotid atherosclerosis and biochemical features were compared among patients with different serum E2levels.Correlation analysis was also performed using binary logistic analysis.Results There were 43 patients with low serum E2level(<134.1 pmol/L), 44 with intermediate E2level(134.1 -198.2 pmol/L)and 42 with high E2level(>198.2 pmol/L).Among 129 patients the carotid artery lesions were detected in 64 cases.There were significant differences in body weight[(61.0 ±10.4), (67.4 ±13.0)and(76.8 ±10.5)kg,t=3.40,P=0.00], waist circumference[(81.5 ±7.9),(86.6 ± 10.7)and(90.0 ±8.0)cm,t=3.57,P=0.00],body mass index(BMI)[(21.6 ±3.2),(23.5 ±3.8) and(26.2 ±3.0)kg/m2,t=3.72, P=0.00], systolic pressure[(140.2 ±14.8),(143.9 ±18.1)and (155.0 ±13.1)mmHg(1 mmHg=0.133 kPa),t=3.18, P=0.04]and TG[(1.46 ±0.88),(2.23 ± 1.08)and(3.35 ±0.9)mmol/L, t =2.66, P=0.04]among patients with low, intermediate and high serum E2levels.The age-adjusted incidence of carotid atherosclerotic plaque in patients with low, intermediate and high E2levels were 25.6%(11/43),56.8%(25/44)and 66.7%(28/42), respectively (χ2=15.73,P=0.00).Compared to low E2level,the risk ratio of carotid atherosclerosis in intermediate and high E2levels was 1.60(95%CI:1.04-2.46, P<0.05)and 1.80(95%CI:1.17 -2.76, P<0.05),respectively.Conclusion Serum E2level is closely associated with carotid atherosclerotic plaque in middle-aged and elderly male type 2 diabetic patients.

Objective: To investigate the prevalence of reproductive system diseases among female workers in a city and related occupational influencing factors. Methods: From June to September, 2016, a cross-sectional survey was used to select 9 944 female workers from six districts of Beijing and then a face-to-face questionnaire survey was performed. Univariate analysis using chi-square test and multivariate logistic regression analysis were used to investigate the risk factors for reproductive system diseases. Results: The age of 9944 female workers ranged from 18 to 65 years (mean 35.53±9.52 years) , and among them, 7 351 (73.92%) were married. The overall prevalence rate of reproductive system diseases among these 9944 female workers during the past three months was 28.29%, and the prevalence rates of hyperplasia of mammary glands, vaginitis, and hysteromyoma were 15.54%, 11.25%, and 6.77%, respectively. After adjustment for age, marital status, education level, and annual family income, the multivariate logistic regression analysis showed that frequent overtime work (odds ratio[OR]=1.119, 95% confidence interval[CI]: 1.070-1.343) , frequent night shifts (OR=1.198, 95%CI: 1.054-1.361) , standing for a long time (OR=1.197, 95%CI: 1.063-1.347) , sitting for a long time (OR=1.327, 95%CI: 1.191-1.479) , heavy workload (OR=1.429, 95%CI: 1.262-1.615) , exposure to lead (OR=1.696, 95%CI: 1.307-2.201) , exposure to mercury (OR=1.452, 95%CI: 1.086-1.940) , and exposure to ionizing radiation (OR=1.679, 95%CI: 1.424-1.980) were associated with reproductive system diseases. Conclusion The prevalence of reproductive system diseases among female workers in Beijing is not optimistic. Reproductive system diseases are associated with frequent overtime work, frequent night shifts, standing for a long time, sitting for a long time, heavy workload, and exposure to lead, mercury, and ionizing radiation.
