ABSTRACT

Gestational diabetes mellitus(GDM)can cause blood glucose disorders in pregnant women and result in adverse maternal-neonatal outcomes.Vitamin D(VD)can improve glucose tolerance and insulin sensitivity,and thus theoretically,VD supplementation during pregnancy could improve glycemic control as well as maternal-neonatal outcomes in GDM patients.Although studies have shown that VD deficiency is associated with poor maternal-neonatal outcomes in GDM patients,no solid conclusion has been drawn with regard to the effects of VD supplementation on these patients.Therefore,here we summarized the research progress of the effects of VD supplementation on glycemic control and adverse maternal-neonatal outcomes in GDM patients,in an effort to guide the clinical VD supplementation during pregnancy.

ABSTRACT

Objective To evaluate the effects of vitamin D supplementation on serum lipid profiles and neonatal prognosis in gestational diabetes mellitus(GDM)patients.Methods The electronic databases including PubMed,Web of Science,Embase,CNKI,and Wanfang Data were searched from inception to February 1,2020.All randomized controlled trials that compared vitamin D supplementation with placebo or without supplementation for GDM women were included.Paper selection,data extraction,meta-analysis and sensitivity analysis were conducted independently by two authors.Risk of bias was assessed using the Cochrane Risk of Bias Tool.The data were analyzed in RevMan 5.3 software and Stata 12.0.Results Totally 17 randomized controlled trials involving 1432 patients(704 in the intervention group and 728 in the control group)were included in the meta-analysis.The results showed that vitamin D supplementation significantly reduced serum total cholesterol [MD=-6.11,95% CI=(-7.17,-5.04)],low-density lipoprotein cholesterol [MD=-10.80,95% CI=(-14.72,-6.89)],and triglyceride [MD=-8.11,95% CI=(-10.09,-6.13)],while significantly increased serum 25-hydroxyvitamin D3 level [MD=45.45,95% CI=(41.98,48.92)] and high-density lipoprotein cholesterol [MD=2.77,95% CI=(1.59,3.96)].In addition,vitamin D supplementation significantly reduced the incidence rate of hyperbilirubinemia [RR=0.49,95% CI=(0.35,0.68)],premature birth [RR=0.44,95% CI=(0.27,0.72)],and neonatal hospitalization [RR=0.44,95% CI=(0.29,0.67)].Conclusions Vitamin D supplementation may regulate the serum lipid profiles in patients with GDM and reduce the incidence of adverse neonatal outcomes.More high-quality RCTs are needed to confirm the findings in our study.

ABSTRACT

HIV/AIDS patients in high prevalence areas with different routes of infection (sexually transmitted 878 cases, 527 cases of intravenous drug user, paid blood donor 652 cases) were choosen for traditional Chinese medicine (TCM) syndrome investigation for one-year clinical follow-up. This paper primarily concluded the nature, location and pathogenesis of AIDS diseases. Deficiency of Yang and Yin, combining deficiency of Qi are the basic deficiency syndromes, while stagnation of dampness, toxic fire are the excess syndromes; the disease location of HIV infector is spleen, main syndrome is deficiency of spleen Qi; the disease location of AIDS patient is kidney, main syndrome is deficiency of spleen and kidney Yang. The pathogenic development tendency is from deficiency of Qi to combining stagnation of dampness and toxic fire, finally to deficiency of Qi and Yin, deficiency of Yang.

ABSTRACT

<p><b>OBJECTIVE</b>To study the use of traditional Chinese medicine (TCM) or both TCM and guideline-recommended Western medicine (WM) in Chinese patients with coronary heart disease (CHD).</p><p><b>METHODS</b>A cross-sectional nationwide survey of 2803 CHD outpatients was completed by collecting information, including general demographic data, disease history, and use of drugs (including TCM and WM).</p><p><b>RESULTS</b>Of the 2712 CHD outpatients with complete drug treatment data, only 3.1% received TCM without any WM for CHD, 30.0% received both TCM and WM recommended by current CHD guidelines, and 66.9% received only WM. Patients with a longer history of CHD or with a history of stroke, were more likely to use TCM. However, 90.6% of CHD patients who used TCM also used certain WM. Furthermore, patients who used more types of TCM tended to use much less WM recommended by current guidelines.</p><p><b>CONCLUSION</b>A substantial proportion of Chinese CHD outpatients use both TCM and WM for secondary prevention of CHD. It is important to assess the effect of combined TCM and WM on major clinical outcomes in Chinese CHD patients.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To observe the real world statins use for secondary prevention in patients with high risk coronary heart disease (CHD) in China.</p><p><b>METHODS</b>Sixty-four hospitals across 31 provinces of China including 32 secondary hospitals and 32 tertiary hospitals were selected for baseline survey. Fifty consecutive outpatients with established history of acute coronary syndrome were recruited in each hospital. Information of these patients including statins use was collected.</p><p><b>RESULTS</b>A total of 2516 high risk CHD outpatients were involved in present report. Mean age of the patients was (65 ± 10) years and 69.4% patients were male. Fifty-seven point nine percent patients were treated with a statin at the time of interview and recommended low-density lipoprotein-cholesterol (LDL-C) target was achieved in 29.8% patients. Percent of statin use and achieving LDL-C goal was significantly higher in male outpatients than in female outpatients. Outpatients admitted in tertiary hospitals were more likely to have achieved their LDL-C targets than those admitted in secondary hospitals. Statin use was more often for patients in South China than patients in North China. The percentage reaching the optimal LDL-C treatment target was the highest in Central China (38.5%) and the lowest in Northeast China (18.5%). At this interview, 68.2% outpatients were prescribed statins and 24.1% prescribed doses of statins were sub-minimal.</p><p><b>CONCLUSION</b>There was a gap between real world statin use and guideline recommendations for secondary prevention in high risk CHD patients in China.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To explore the changes of serum leptin, soluble leptin receptor (SOB-R) concentrations and free leptin index (FLI) throughout the puberty in females, and estimate the effects of genetic and environmental factors on these indices.</p><p><b>METHODS</b>The population studied consists of 180 pairs of twins in 6 to 18 years old: 132 pairs of monozygotic twins and 48 pairs of dizygotic twins, who were all from Qingdao city, Shandong Province. Anthropometric and sexual characteristics were examined, fasting serum leptin and SOB-R contents were assayed by immunoradiometric assay and ELISA respectively.</p><p><b>RESULTS</b>Serum leptin concentrations increased and SOB-R decreased throughout puberty (P < 0.05), brought out a sustained increase of FLI, especially in 7-9 and 12-14 years old (from 10.1 to 32.3 and 41.8 to 82.1 respectively); Leptin and FLI were positively, and SOB-R negatively correlated with morphological indices (correlation coefficients from 0.54 to 0.76, -0.23 to -0.42, respectively). Heritability of girl's serum leptin, SOB-R and FLI were 0.37, 0.84, 0.46 respectively.</p><p><b>CONCLUSIONS</b>Serum free leptin index surge at 7-9 and 12-14 years old might be a predictor or trigger of the puberty onset and menarche, respectively; FLI might be determined by both genetic and environmental factors. Leptin should be substantially influenced by environment and reflect the fat mass of body compositions. SOB-R should be predominantly controlled by genetic factors yet. Genetic influence might be important in pubertal development and metabolic disorders.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To investigate DNA repair in CHL cells and HeLa cells after DNA damage induced by different oxidative agents.</p><p><b>METHODS</b>CHL cells and HeLa cells were exposed to various damaging agents, CHL cells: H(2)O(2) for 25 min, K(2)Cr(2)O(7) for 105 min, doxorubicin (Dox) for 75 min HeLa cells: H(2)O(2) for 25 min, K(2)Cr(2)O(7) for 105 min; then cells were continuously cultured for 0-3 h after washing. Alkaline single cell gel electrophoresis (ASCGE) assay was used to detect DNA strand breaks.</p><p><b>RESULT</b>(1) DNA strand breaks were induced in CHL cells after exposure to H(2)O(2) K(2)Cr(2)O(7) or Dox, which were repaired evidently after continuous culture for 1 h(P<0.01). The damages induced by H(2)O(2) or K(2)Cr(2)O(7) were repaired completely after culture for 2-3 h. However, the demage induced by Dox was repaired incompletely. (2) DNA strand breaks were induced also in HeLa cells after exposure to H(2)O(2) or K(2)Cr(2)O(7), which were repaired evidently after continuous culture for 0.5 h(P<0.01),and completely after culture for 1 h. (3) The regression coefficient related to the rate of comet cells and repair time was statistically different (P<0.05) between CHL cells and HeLa cells.</p><p><b>CONCLUSION</b>DNA damage induced by Dox is repaired more difficult than that induced by H(2)O(2) or K(2)Cr(2)O(7). The repair initiates immediately after DNA damage in both of cells, but more rapidly in HeLa cells than in CHL cells.</p>
