OBJECTIVE:
To investigate the association of the polymorphism of angiotensin-converting enzyme (ACE) gene and pregnancy-induced hypertension (PIH) in Chinese Women.
METHODS:
We systematically searched CNKI, Wanfang database, VIP and PubMed from database construction to March 2012 to collect case-control studies. Stata 11.0 was used for meta analysis after evaluating the quality of studies and collecting the data. The association was assessed by odds ratio (OR) with 95% confidence intervals (CIs). Publication bias was analyzed by Begg's funnel plot and Egger's regression test.
RESULTS:
We identified 11 case-control studies on association between ACE gene polymorphism and PIH, which included 806 PIH patients and 900 controls. Overall, significant association was found between ACE gene polymorphism and PIH risk [for D vs I: OR=2.73, 95% CI (1.64, 4.24), P<0.001; for DD+DI vs II: OR=3.11, 95% CI (1.98, 4.90), P<0.001; for DD vs II: OR=5.00, 95% CI (2.30,10.88), P<0.001; for DI vs II: OR=1.97, 95% CI(1.53, 2.53), P<0.001].
CONCLUSION
Chinese women with D allele gene deletion have a higher risk of suffering pregnancy induced hypertension syndrome.

OBJECTIVE:
To investigate the association of 7 novel genetic loci identified in a recent genome-wide association studies (GWAS) with T2DM in Chinese Dong populations.
METHODS:
A case-controlled study was performed in individuals of Chinese Dong nationality. The genotypes of PARD3B (rs849230), LOC729993 (rs149228), EPHA4 (rs16862811), HNT (rs3099797), PTPRD (rs17584499 and rs649891), TOMM7 (rs2240727) genes were determined by Multiplex PCR-SNaPshot. The independent association between each polymorphism and T2DM was assessed by unconditional binary logistic regression analysis. The gene-environment interaction was assessed by marginal structural linear odds model.
RESULTS:
A total of 209 cases of T2DM and 209 control subjects were enrolled in the study. The polymorphism of rs2240727 in TOMM7 gene was associated with T2DM (OR=1.50, per copy of the risk T allele, P=0.004). In addition, CT (OR=2.07, 95% CI: 1.14-3.76) and TT (OR=2.75, 95% CI: 1.46-5.17) were risk genotypes for T2DM. After the correction for multiple test, the association remained significant (all P<0.05). After adjustment for the confounders of age, gender, and BMI, the association remained significant (P<0.05). The results of interaction analysis indicated that there were interaction between rs2240727 locus and BMI, WHR, hypertension and family history of diabetes. After adjustment for age and gender, the results of relative excess risk of interaction (RERI) were 1.5430 (95% CI: 0.5797-2.5062), 2.6520 (95% CI: 1.7516-3.5524), 2.9131 (95% CI: 1.7959-4.0303), 4.2062 (95% CI: 1.1686-8.2439), respectively (all P<0.05).
CONCLUSION
The rs2240727 genetic variant in TOMM7 is associated with T2DM in Chinese Dong population. There is positive interaction between rs2240727 and BMI, WHR, hypertension as well as family history of diabetes.

Objective: To study the factors affecting the survival and prognosis of patients with intracranial ependymoma. Methods:From January 2008 to January 2018, the prognoses of 276 patients with intracranial ependymoma were analyzed using Log-rank and Cox model analysis. The variables included sex, age, tumor location, tumor diameter, resection extent, pathological grade, Ki-67 index, postoperative radiotherapy, and postoperative chemotherapy. Results: Tumor location, resection extent, and postoperative radiothera-py could all affect the overall survival (OS) and progression-free survival (PFS) of patients with intracranial ependymoma (P<0.001) and independently affected the OS (P<0.001, P<0.001, and P=0.002, respectively) and PFS (P<0.001, P<0.001, and P=0.001, respectively). The Ki-67 index was an independent factor affecting PFS in patients with intracranial ependymoma (P<0.001). The supratentorial loca-tion and Ki-67 index≥10% were independent risk factors indicating poor prognosis (P<0.001). Total resection and postoperative radio-therapy were protective factors (P<0.001 and P=0.001, respectively). Conclusions: Tumor location, resection extent, Ki-67 index, and postoperative radiotherapy are independent factors affecting the prognosis of intracranial ependymoma. It is helpful to extend the PFS and OS of patients through complete tumor resection or postoperative radiotherapy.

To estimate the national prevalence of paternal postpartum depression in China and evaluate its association with maternal postpartum depression.
Methods: Systematic literature searches were conducted in databases including PubMed, Web of Science, Embase, Medline, China National Knowledge Infrastructure (CNKI), Wangfang Database, Chinese science & technology journal database (VIP) and SinoMed database. The articles reported the prevalence of paternal postpartum depression in China were collected from inception to October 1, 2015. Random effect models were used to calculate pooled estimates and 95% confidence intervals. Subgroup analysis were undertaken by period of measurement, case identification, study location and study quality.
Results: Fourteen studies with a total sample size of 3 819 partners were included in this study. The pooled estimate of paternal postpartum depression was 13.6% (95% CI 8.7%-21.3%). The Pearson correlation coefficien between maternal PPD and paternal PPD was 0.295 (95% CI 0.218-0.367). The subgroup analysis showed that the estimates of paternal PPD in 0-5+6 weeks postpartum, 6-8 weeks postpartum and 8+1-24 weeks postpartum were 28.7%, 11.4% and 5.5%, respectively; when the rating scale was used as case identification method, the estimate of paternal PPD was 16.8%, and it was 4.1% when interview was used. The estimate of paternal PPD in inner areas was 22.2%, in coastal areas was 13.3% and in Hongkong/Taiwan was 7.8%. In studies with lower quality, the estimate of paternal PPD was 23.0%, and it was 9.1% in studies with higher quality.
Conclusion: The national prevalence of paternal postpartum depression in China was at a high level, particularly during the postpartum 0-5+6 weeks. Paternal postpartum depression also showed a moderate positive correlation with maternal postpartum depression.

OBJECTIVE:
To analyze the intervention efficacy of lamivudine on liver dysfunction in patients undergoing anti-tuberculosis treatment for pulmonary tuberculosis complicated with chronic hepatitis B.
METHODS:
Corresponding data were retrieved from PubMed, Web of Science, Embase, the Cochrane Library, Chinese Biomedical Literature (CBM), VIP, China National Knowledge Infrastructure (CNKI) and Wanfang Database with randomly controlled trials regarding the chronic hepatitis B and tuberculosis by lamivudine. Statistical analysis was performed by Meta-analysis using Stata11.0.
RESULTS:
Fifteen randomly controlled trials including 967 chronic hepatitis B and tuberculosis cases met the inclusion criteria (564 cases in observation group and 403 cases in control group). Meta-analysis showed that the values of ALT, AST, TBIL and HBV-DNA load in the observation group were lower than those in the control group. The values of standardized mean difference (95% CI) were -2.58 (-3.55, -1.60), -2.43 (-3.33, -1.54), -1.56 (-2.18, -0.94) and -6.91 (-8.90, -4.92), while the combined effect of OR values for liver damage was 0.11 (0.06, 0.19). There were significant differences in the combined effect of each value between the two groups (P<0.05).
CONCLUSION
The intervention efficacy of lamivudine on liver dysfunction in patients undergoing anti-tuberculosis treatment for pulmonary tuberculosis complicated with chronic hepatitis B patients was good, which can reduce hepatitis B viral load levels.

OBJECTIVE To investigate the mechanism of the inhibitory effect of total flavonoids from Taraxacum mongolicum on high-fat diet-induced obesity in mice through modulation of intestinal flora. METHODS Twenty-four C57BL/6J mice were randomly divided into blank group, model group and T. mongolicum total flavonoid group, with 8 mice in each group. Except for the blank group, the other 2 groups were given a high-fat diet, while T. mongolicum total flavonoid group was given T. mongolicum total flavonoid [400 mg/(kg·d)] intragastrically, once a day, for 8 consecutive weeks. During the experiment, the food intake of each group of mice was recorded. After the last medication, the body mass, fat weight, blood lipid level and pathological changes of liver and epididymal fat in mice were evaluated to observe the effect of T. mongolicum total flavonoid on the treatment of obesity in mice. The changes in abundance and structure of intestinal flora in mice were detected by amplicon sequencing; the effects of T. mongolicum total flavonoids on fat metabolism related genes were analyzed by qPCR. RESULTS Compared with model group, the body weight of mice in T. mongolicum total flavonoids group was decreased significantly (P<0.05); the levels of total lipid cholesterol, triglycerides, and LDL cholesterol were all decreased significantly (P<0.01), and the level of HDL cholesterol was increased significantly (P<0.01); the fat indexes of inguinal white adipose tissue and epididymal white wind_lz@hactcm.edu.cn adipose tissue were significantly reduced (P<0.05); significant improvement in hepatocellular steatosis and adipose cytopathy were significantly improved; mRNA expressions of COX7A1 and COX8B were significantly upregulated (P<0.05). The results of bacterial colony detection showed that compared with the model group, there was a rising trend in the diversity of the bacterial colony in T. mongolicum total flavonoids group, and the Sobs index characterization and β diversity were increased significantly (P<0.05). Relative abundances of Blautia, norank_f_Ruminococcaceae, Bilophila, Alistipes, classified_f_Ruminococcaceae, Parabacteroides, norank_f_Desulfovibrionaceae, Anaerotruncus were significantly up-regulated(P<0.05), while those of Faecalibaculum, Erysipelatoclostridium, GCA-900066575, Tuzzerella, Lactobacillus, norank_f_norank_o_RF39, achnospiraceae_FCS020_group were significantly down-regulated (P<0.05). CONCLUSIONS T. mongolicum total flavonoids can reduce body mass, fat weight and blood lipid levels, and repair the pathological damage to liver and epididymal fat in obese mice, which is related to improving intestinal flora disorders caused by high-fat diet.
