Objective To analyse the maternal and perinatal morbidity after 40 weeks and postdate pregnancy,and to research suitable time of labor induction. Methods Clinical data of 357 pregnant women after 40 weeks with normal menstrual period were analysed.They were divided into four groups according to the different weeks of gestation. Results There were no significant difference in the four groups for maternal and perinatal morbidity,the rate of spontaneons labor,the degree of cervical repine and the successful rate of labor induction.The successful rate of artificial rupture of membranes was higher in the groups with Bishop score ≥6(P

OBJECTIVE To appraise the bacteriostatic and blocking effect and cost construction of different kinds of materials.METHODS To divide all items into three parts at random:cotton fabric,paper-plastic package,and medical grade wrinkle paper and to study the bacteriostatic and blocking effect and cost construction of them.RESULTS Paper-plastic package and medical grade wrinkle paper had better bacteriostatic and blocking properties than cotton fabric.Comparing with cotton fabric,paper-plastic package and medical grade wrinkle paper could reduce the cost separately by 27% and 50%;the cost of wrinkle paper was lower than paper-plastic package by 32%.CONCLUSIONS Paper-plastic package and wrinkle paper have better effect on blocking bacteria and less cost than cotton fabric,which deserve more extensive application in clinic.

Objective To investigate the impact of subclinical hypothyroidism (SCH) on macrovascular complications in elderly type 2 diabetic patients.Methods A total of 1170 hospitalized elderly patients with type 2 diabetes mellitus were enrolled in the study through systematic sampling and underwent testing for blood biochemical indicators, thyroid function and C peptide.Parameters for macro-vascular complications, including the ankle/brachial index (ABI), transcranial Doppler vascular ultrasound (TCD), electrocardiogram (ECG), ejection fraction (EF), history of coronary heart disease, and hypertension grading were also monitored.Results All the subjects were divided into two groups based on the thyroid stimulating hormone (TSH) level: the euthyroid group (4 mU/L≥TSH＞0.4 mU/L) and the SCH group (TSH＞4 mU/L), and the latter was further sub-grouped into the mild SCH group (10 mU/L≥TSH＞4 mU/L) and the severe SCH group (TSH＞10 mU/L).ABI was significantly decreased in SCH (R/L: 0.86/0.92, P＜0.01).Levels of basal C-peptide (CP0) and post glucose-challenge C-peptide (CP1-3) were higher in the SCH group than in the euthyroid group [(2.16±0.93)pg/L vs.(1.56±1.05)pg/L, (0.53±0.25)pg/L v, (0.38±0.37),(0.72±0.23) pg/L vs.(0.56 ±0.32) pg/L, (6.21± 2.69) pg/L vs.(4.46 ± 2.62) pg/L,respectively, P＜0.01 for all].EF was higher in the SCH group than in the euthyroid group[(70.87± 6.66)％ vs.(65.10 ± 8.08％), P＜ 0.01].There were no significant differences in other biochemical indicators, ECG, TCD, history of coronary heart disease, hypertension grading and intervention treatment (P＞0.05 for all).Conclusions Lower extremity atherosclerotic disease has a higher incidence in elderly type 2 diabetic patients with SCH and occurs earlier than other macrovascular complications.Elevated TSH levels and insulin resistance may be the major causes.

Objective To study the effects of community comprehensive intervention model on osteoporosis, in order to provides a reference for osteoporosis health education work. Methods A multistage stratified random cluster sampling was applied to conduct a survey in Jiangsu province, in accordance with the economic level and geographic location. Nanjing, Nantong and Xuzhou cities were sampled, three urban streets were sampled in every district , respectively. A total of 1 500 40-69 years old community residents were screened, 619 high-risk participants for osteoporosis were arranged into the intervention group, and a total of 590 residents from the same communities were chosen as control group, who were gender- and age-matched with the intervention group. The intervention group residents received health management and comprehensive intervention, after half a year, a self-designed questionnaire was used to investigate the effects. Results Compared with control group, after six months, knowledge of intervention group related to osteoporosis awareness was improved significantly, such as the most serious harm to human body for osteoporosis (χ2=24.27), characteristic of osteoporosis (χ2=11.05), basic supplements to improve bone health (χ2=60.65) , the recommended daily calcium intake to postmenopausal women and the elderly (χ2=26.80), the difference was statistically significant (P<0.05); daily behavior related to diet and exercise of intervention group has improved significantly, such as drinking milk or itsproducts less than 3 days a week (χ2=25.83), eating beans and products for less than 3 days a week (χ2=19.20), drinking coffee for more than three days a week (χ2=7.77), not often taking outdoor activities (χ2=18.55) ,(P<0.05);Diseases and symptoms related to osteoporosis in intervention group was significantly reduced (P<0.001). Conclusions The osteoporosis is one of the most important public health problem for Jiangsu province, the work for osteoporosis prevention and control should be emphasized in community.

Objective To study the genotype distribution of insulin receptor substrate-2(IRS-2)gene 1057G/A polymorphism in Han population from Southwest China,and to explore its association with the metabolism of glucose and lipids,insulin resistance and islet?-cell function in type 2 diabetic patients and subjects with impaired glucose tolerance(IGT).Methods A total of 929 Hans[462 patients with type 2 diabetes(DM group) and 164 subjects with IGT(IGT group)and 303 normal controls(NC group)]from Chongqing and nearby regions were screened for 1057G/A polymorphism of IRS-2 gene by PCR-RFLP assay.Body mass index(BMI),plasma glucose,serum insulin and lipid profile,high-sensitive C-reactive protein(hsCRP)and non-esterified fatty acid were measured.Homeostasis model assessment of insulin resistance(HOMA-IR)and disposition index(DI)were used to estimate insulin resistance and?-cell function respectively.Results In DM group,A allele frequency was significantly lower than that in NC group(0.326 vs 0.388,X~2=6.19,P=0.01).Compared with NC group,AA genotype frequeney was lower and GG genotype frequeney was higher in DM group(0.104 vs 0.135 and 0.452 vs 0.360 respectively,X~2=6.80,P

Objective:To study the antimalarial mechanism of benflumetol (B). Methods: Flow cytometry (FCM) was used to analyze the effects of B and chloroquine (CQ) on DNA content of Plasmodium berghei and pH value of the lysosome of malarial parasites. Results: DNA content of the plasmodia not treated with any drugs was not changed in 24 hours,while benflumetol could decrease the DNA content: the DNA content began to decrease 2 h after the drug administration and reached the minimum by 16 h, but somewhat increased at 24 h after administration. The pH in the lysosome increased 1 h and restored premedication level 4 h after benflumetol administration. Chloroquine had the same effects on DNA and lysosome pH of malarial parasites.Conclusions: The antimalarial mechanism of benflumetol is directly related to its effect to inhibit the synthesis of DNA.

OBJECTIVE: To perform the validation and analysis of forensic parameters of Goldeneye DNA ID 26Y system. METHODS: Based on the validation rules of Scientific Working Group on DNA Analysis Methods (SWGDAM), the kit was assessed from several parts, as test of PCR system, reproducibility, accuracy, and sensitivity, etc. And Y-STR loci of 517 unrelated healthy individuals from Eastern China were genotypes by this kit. The distribution and frequency of haplotype were calculated and forensic parameters of the kit were assessed. RESULTS: The complete profiles can be obtained even when the PCR reaction volume with 6.25 microL. And correct profile was obtained with DNA down to 125 pg. No reproducible peaks were detected with the DNA of common animals and microorganism with the kit. For the male-male mixture testing, average 70% of the minor alleles were obtained when the ratios of 1:19 and 19:1. For the male-female mixture testing, results showed that the sensitivity of the kit was no compromised with the addition of female samples. CONCLUSION The validation studies demonstrated that Goldeneye DNA ID 26Y system has good sensitivity and specificity, and suitable for mixture testing. The polymorphism of 26 Y-STR loci included in this kit are good for forensic application.
