Chinese Journal of Postgraduates of Medicine 2017;40(2):125-128
Objective To compare the clinical characteristics of pregnant women with gestational diabetes mellitus (GDM) and normal gestational glucose metabolism at the 25th weeks of pregnant. Methods Sixty-eighty patients with GDM (GDM group) and 68 patients with normal blood glucose(control group) were enrolled in this study. During 25 weeks of pregnancy, oral glucose tolerance test (OGTT), blood pressure, fasting insulin, glycosylated hemoglobin, uric acid, triglyceride, total cholesterol, high density lipoprotein cholesterol and low density lipoprotein cholesterol were measured and body mass index (BMI), homeostasis model of assessment for insulin resistence index (HOMA-IR), insulin sensitivity index (ISI) were computed. The results were compared between two groups. Results The age in GDM group was significantly higher than that in control group: (31.38 ± 0.54) years vs. (29.50 ± 0.56) years, P<0.05. The systolic pressure in two groups had no significant difference (P>0.05), but diastolic blood pressure in GDM group was significantly higher than that in control group:(73.2 ± 0.8) mmHg vs. (70.9 ± 0.8) mmHg, 1 mmHg=0.133 kPa, P<0.05. The body weight and BMI in GDM group were significantly higher than that in control group:(65.67 ± 1.76) kg vs. (57.76 ± 1.11) kg, (24.77 ± 0.61) kg/m2 vs. (22.11 ± 0.42) kg/m2, P<0.01. The levels of glycosylated hemoglobin, fasting insulin and HOMA- IR in GDM group were significantly higher than those in control group (5.546 ± 0.746)% vs. (5.085 ± 0.034)% , (17.870 ± 1.015) mU/L vs. (14.400 ± 0.634) mU/L, 4.192 ± 0.271 vs. 2.645 ± 0.128, but the level of ISI in GDM group was significantly lower than that in control group:0.014 ± 0.001 vs. 0.020 ± 0.001, and there were significantly differences (P<0.01). The levels of uric acid, triglyceride, total cholesterol, high density lipoprotein cholesterol and low density lipoprotein cholesterol in two groups had no significant differences (P>0.05). Conclusions Compared to those with normal blood glucose, the patients with GDM have the characteristics of higher age, higher body weight, higher BMI, higher diastolic blood pressure , higher level of insulin, insulin resistance and decreased insulin sensitivity.

Methods Total RNA was extracted from the deltamethrin-resistant (R-lab) and -sensitive (S-lab) isolates, mRNA was obtained after purification. Double stranded cDNAs were synthesized after reverse transcription. Two subtractions were performed by suppression subtractive hybridization with S-lab as tester and R-lab as driver or S-lab as driver and R-lab as tester. Enriched different expressed cDNA was cloned into pMD18-T vector to construct subtractive libraries. Results The subtracted cDNA libraries contained 580 and 477 positive clones respectively. The PCR results of 150 clones picked randomly from each library showed that the positive ratio of constructed cDNA libraries was 93%, with a length of cDNA fragments ranged from 150 bp to 750 bp. Conclusion The suppression subtracted cDNA library of deltamethrin-resistant Ae. albopictus is constructed.

Objective To assess the value of combined detection of enterovirus nucleic acid and antibody in early etiological diagnosis for hand-foot-and-mouth disease ( HFMD).Methods A case-control study was conducted.A total of 1 066 cases of children clinically diagnosed with HFMD from Hangzhou Children′s Hospital were involved into the research group from January to June 2014, consisting of 401 common cases and 665 severe cases; Throat swabs and serum samples from these children underwent combined detection for EV71/CA16/EV of enterovirus nucleic acid by fluorescence quantitative RT-PCR and for EV71/CA16-IgM by ELISA.All data were analyzed with SPSS 16.0.Results The total positive rate of enterovirus nucleic acid EV71/CA16/EV by fluorescence quantitative RT-PCR in the 1 066 cases of children clinically diagnosed with HFMD was 75.52%( 805/1 066 ) ( 95%CI: 72.80%-78.05%).But the total positive rate of combined detection was 91.46%( 975/1 066 ) ( 95%CI:89%.58-93.04%).The total positive rate of combined detection is higher than that of RT-PCR test(χ2 =98.338,P=0.000).The positive rate of EV71 type of combined detection was 64.63%(689/1 066)(95%CI:61.67%-67.49%),which is 15.38%higher than that of RT-PCR test 49.25%(525/1 066)(95%CI:46.21%-52.29%)(χ2 =51.453, P=0.000).In 665 severe cases of HFMD, the total positive rate of combined detection was 96.69%(643/665)(95%CI:94.95%-97.87%), which is higher than that of RT-PCR test 79.25%(527/665)(95%CI:75.92%-82.22%)(χ2 =95.607, P =0.000).In the severe cases, the positive rate of EV71 type of combined detection was 87.52%( 582/665 ) ( 95%CI:84.71%-89.89%) , which is 18.95% higher than that of RT-PCR test 68.57%(456/665) (95%CI:64.87%-72.06%) (χ2 =69.665, P=0.000).In the fatal cases, the positive rate of EV71 type of combined detection was 95.92%(94/98) (95%CI:89.28%-98.68%).Conclusions The combined detection of enterovirus nucleic acid and specific IgM antibody can significantly increase the positive rate of HFMD, especially for severe cases.The combine detection increases both the total positive rate and EV71 positive rate.Thus it has a high potential for becoming a new guidelines for laboratory diagnosis of HFMD.
