Obesity increases the risk of ovarian cancer,and it is associated with the poor prognosis of ovarian cancer.Its pathogenic mechanism may be associated with the increased level of serum estrogen,insulin and insulin-like growth factors-1 induced by obesity and a variety of adipocytokines,which has an impact on the therapeutic result and prognosis of ovarian cancer.Maintaining a proper weight may prevent the development of ovarian cancer.

Objective The impact of complement Clq on inflammation in beta amyloidstimulated microglia.Methods After the cultured BV-2 microglial cells were treated with 100mg/L beta-amyloid fibers (fAβs),some of them were given C1q,others wcrc given C1q and C1qA.Then,interleukin-6 (IL-6) and tumor necrosis factor α (TNF α) in the supernatant and cell lysate were determined by the sandwich ELISA.Results A significant increase in TNF-α started at giving 50 nmol/L C1q after 100 mg/L fAβs (F =1177.27,P＜ 0.05),while the release of TNF-α was significantly suppressed by using 50 nmol/L C1qA on basis of this(P＜0.05).The level of IL-6 showed no above change.Conclusions C1q may enhance the inflammation of Aβ-induced BV-2 microglia cells and TNF-α may play important role in this effect.

Objective To investigate Monilia infection and adverse pregnancy outcomes of pregnant women in labor.Methods Before informed consent,542 cases of pregnant women in labor were collected in Obstetrics Department of Maternity and Child Healthcare of Maoming City from January 2013 to April 2014,and all of these cases were examined by Monilia inspec-tion of vaginal secretions.All of these cases were 20 to 30 years old,without vaginal pathogenic infection symptoms,but in-cluded in a few of formulation of clinical features of vaginal Candida infection.With the two methods of 10% potassium hy-droxide solution wet sheet and Gram staining,if blastospore or pseudohypha of Candida mycoderma were found out in the two methods under microscope,this case was diagnosed as positive result,otherwise as negative result.Respectively choosing positive cases as observation group,and negative cases as control group,the indexes of premature rupture of membranes,per-ineum wound infection,neonatal thrush and neonatal diaper rash of the two groups were recorded.The statistical method:e-numeration data by chi-square test,measurement data using analysis of varianc.Results The positive rate of Monilia was 23.1% (125/542),higher than 19.3% reported in domestic.The incidence rates of neonatal diaper rash,premature rupture of membranes,neonatal thrush and perineum wound infection of the observation group were respectively 19.2%,8.0%, 16.8% and 12.8%,all much higher than the control group respectively was 8.4%,1.2%,3.8% and 1.7%,(χ2 =12.578~29.273,all P <0.01).Conclusion Monilia infection of pregnant women in labor could increase the chance of adverse preg-nancy outcomes.Healthy or clinical doctors should suggest that pregnant women early carry out routine examination and ear-ly treatment,in order to prevent adverse pregnancy outcomes.

Objective:To evaluate association of peripheral blood brain-derived neurotrophic factor (BDNF) with Alzheimer's disease (AD) .Methods:Databases including Pubmed, Cochrane library, Web of science, Embase, China National Knowledge Infrastructure, CBM disc, VIP-CSTJ and Wanfang Data were used to collect case-control studies related to the concentration of BDNF in peripheral blood of dementia patients with Alzheimer's type(DAT) and mild cognitive impairment(MCI). After extracting data and appraising the quality of the included studies, meta-analysis were conducted using Review Manager 5.3 and CMA 3.0.Results:A total of 51 articles were included in the analysis, with a total subjects of 7 182, including 2 673 subjects in DAT group, 1 506 subjects in MCI group, and 3 003 subjects in control group.The Meta-analysis showed that the levels of peripheral blood BDNF in patients with DAT were significantly lower than normal control group(SMD=-0.71, 95% CI : -0.99--0.43, P<0.001) ( n=5 111), and there were no statistical differences in peripheral blood BDNF levels between MCI group and control group and between DAT group and MCI group.The subgroup analysis showed that the level of serum BDNF in patients with DAT (SMD=-0.85, 95% CI: -1.15--0.55, P<0.001)( n=4 425) and MCI(SMD=-0.38, 95% CI: -0.62--0.14, P=0.002)( n=2 476) was significantly lower than that in normal control group, and the level of serum BDNF (SMD=-0.76, 95% CI: -1.37--0.16), P=0.01)( n=1 630) in patients with DAT was lower than that in MCI; However, there were no statistical difference among DAT, MCI and control groups in the level of plasma BDNF( P>0.05). Conclusion:The patients with DAT and mild cognitive impairment have lower level of serum BDNF, which suggesting that serum BDNF level may be a potential biomarker for early diagnosis of AD.
