ObjectiveTo study the value of plasma corticotropin-releasing hormone (CRH) and the fetal fibronectin (fFN) in vaginal secretions and cervical length in predicting preterm labor.MethodsThe plasma CRH levels and fFN levels in vaginal secretions from 24 -37 weeks pregnant woman checked up in our hospital from Dec.2009 to Dec.2010 were detected by ELLISA method.The changes of these three indexes were observed with the pregnant time and were analyzed according to different pregnancy outcomes.Results Among the 112 cases of pregnant women,premature delivery in 54 cases,full-term birth 58 cases.At the 24 week of pregnancy,there were significant difference on the cervical length( [2.8 ±0.4]cm vs [3.3 ±0.5]cm,t =3.254,P =0.021 ) between premature delivery group and full-term birth group.At the 28 - 30 week,31 -32 week,33 - 34 week,35 - 36 week,the CRH were ( 162.33 ± 16.49 ) ng/L,(60.01:±: 14.56) ng/L;(352.12 ±61.01 )ng/L,( 118.04 ±53.74)ng/L; (364.55 ±56.71 )ng/L,( 122.95 ±71.41 )ng/L; (372.78 ±149.89)ng/L,(124.00 ± 19.05 )ng/L respectively in premature delivery group and full-term birth group,and there were significant differences on CRH at the four different pregnant time(t =3.687,6.875,8.652,8.524,respectively,P ＜ 0.05 ).It shows better sensitivity ( 97.92％ ),specificity ( 90.00％ ),positive predictive value(95.92％ ) and negative predictive value(94.73％ ) in predicting premature delivery by detection of CRH,fFN combined with cervical length.ConclusionDetection of plasma CRH,fFN combined with cervix length measurement can improve the predictability of premature and provide a good,reliable clinical basis for the early diagnosis and treatment for preterm premature.

Objective To explore the effects of passive smoking on vascular endothelial function in office women.Methods Totally,94 healthy office women volunteers from urban(36 women)and townships or towns(58 women)were divided into three groups based on the extent of their daily exposure to passive smoking,group A exposed to one to eight cigarettes,group B exposed to nine to 15 cigarettes,and group C exposed to more than 15 cigarettes,respectively,with 20 healthy young women without exposure to passive smoking as controls.Internal diameter of the brachial artery Was measured by color Doppler ultrasound scanning for each of the participants and its changes were observed before and after congestive reaction of the brachial artery test and nitroglycerin test.Results Thirteen of 36 office women from urban and 38 of 58 from townships or towns exposed to passive smoking of more than eight cigarettes daily,with chi-square of 7.74,P=0.0054.The brachial artery in groups A,B and C dilated less than that in the controls did.The brachial artery in group C dilated less than that in the groups A and B did.Conclusion Passive smoking could damage vascular endothelial dilatation function in office women.

Objective To investigate the anticancer effect of oxymatrine on cervical cancer cell line (HeLa). Methods MTT assay was used to detect the anti-proliferative effect of oxymatrine.Transwell chamber was used to detect the anti-metastatic effect of oxymatrine.Real-time PCR was used to detect the mRNA levels of MMP-2 and MMP-9.Western blot was used to detect the protein levels of MMP-2,MMP-9,AKT,p-AKT and GADPH. Results We found that application of oxymatrine significantly inhibited the growth of HeLa cells at the concentration above 0.8 mg/mL.We also found that oxymatrine (0.1,0.2 and 0.4 mg/mL)inhibited the invasion of HeLa cells under cytotoxic dose,which was (77.07±20.43)%,(53.95±18.17)% and (20.35±11.20)% of cells that migrated through the matrigel when compared with those of non-oxymatrine treatment group (P<0 .0 5 ). Further research found that oxymatrine (0.1,0.2 and 0.4 mg/mL)could reduce the expression of MMP-2 at the mRNA level,i.e.(82.76±8.71)%,(39.51±12.79)% and (21.53±5.38)% of the expression level when compared with that of non-oxymatrine treatment group (P<0 .0 5 ).The protein expression level of MMP-2 in 0 .4 mg/mL group was (64.69 ±16.52)% of non-oxymatrine treatment group (P<0.05).The phosphorylation level of AKT in 0.4 mg/mL group was (41.27±7.13)% of non-oxymatrine treatment group (P<0.05).Conclusion Oxymatrine can inhibit the invasion of HeLa cells by reducing the expression of MMP-2 via inhibiting the activity of AKT signal pathway.All together,our findings bring new insights into the mechanism of the anticancer effects induced by oxymatrine treatment.

This paper introduces the nursing care of 1556 patients with nasal packing silicone ventilation tube after func-tional endoscopic sinus surgery. Meticulous nursing care during nasal packing silicone ventilation tube could alleviate patients' discomfort obviously. It was emphasized to suck at exact time according to the patients' demands, adopt effective suction means to alleviate the damage of nasal mucosa,such as suction in the tube or in the bottom of the tube, take measures to promote the cleaning of secretion,which could improve the breath and sleep,as well as shorten the time of recovery.

With the scientific development and social progress, people advocate late marriage and late childbirth, and some women because of marriage can't conceive naturally and need to lead to assisted reproduction, the elderly primipara population gradually increased. Postpartum depression is a common mental disease occurring in the puerperium, which seriously endangers the health of mother and baby, especially for the elderly primipara. This article summarized the intervention status of postpartum depression in elderly primipara from the primary prevention and two levels of prevention after birth, and provided the basis for reducing the incidence of postpartum depression.
