Objective To evaluate factors associated with labor pain and delivery outcomes.Methods From Jul.to Dec.2009,111 normal singleton cephalic presentation pregnancies (including 5 elderly parturient) who delivered at the Department of Obstetrics and Gynecology,Second Affiliated Hospital,Zhejiang Chinese Medical University were enrolled in this study to evaluate the relationship between factors of labor pain and delivery outcomes.The labor pain of latent phase and active phase were scored by the visual analogue scale (VAS).Factors associated with pain included the age of parturient,the number of gravidity and parity,occupation,education profile,dwell location,etc.The questionnaire was designed by ourselves.Childbirth awareness,psychological preparation of delivery,emotional controllability,couple relationship,the relationship of parturient and mother-in-law,the relationship of parturient and parents,family economic status,use of sedative during the labor process and delivery outcomes were collected and analyzed.Results (1)Factors associated with pain:in the latent phase,the rate of moderate labour pain of 1/5 in women with more than 35 years old was statistically lower than 76.4％ ( 81/106 ) in suitable age group (P＜0.05 ).The women with a good understanding about delivery had a statistically lower rate of moderate pain of 64.7％( 44/68 ) than 88.4％ ( 38/43 ) of those having a poor understanding( P＜0.05 ).The women who had a better couple relationship had a significandy higher rate of moderate pain of 77.2％ (78/101) than 4/10 of those who had a general couple relationship ( P＜0.05 ).There was significant difference in rate of moderate pain between pluripara group ( 50.0％,11/22) and primipara group(79.8％,71/89;P＜0.01 ).In the active phase,women with tense,scared or a poor emotion control expressed significantly severe labour pain(59.0％,36/61 ) than 35.6％ ( 16/45 ) in well-prepared group.The rate of severe labour pain in good control of emotion group of 44.8％ (43/96) was a statistically lower than 9/10 in poor control group.There was a statistically lower severe labour pain in women given by sedatives ( 29.2％,7/24 ) than 54.9％ (45/82) in women without sedatives treatment (P ＜ 0.05).(2) Delivery outcomes:in latent phase,the rates of fetal distress and cesarean section were 36.6％ (30/82) and 39.0％ (32/82) in moderate pain group,which were significantly higher than 13.8％ (4/29) and 17.2％ (5/29) in mild pain group.In active phase,the rate of fetal distress,cesarean section and postpartum hemorrhage were 36.5％ ( 19/52),40.4％ (21/52) and 13.5％ (7/52) in severe pain group,which were significantly higher than [18.5％ (10/54) ;20.4％ (11/54) ;0] in moderate pain group (P＜0.05).Conclusions Women with poor understanding of delivery,tense,scared,poor emotion control,young age and uniparous have severe labour pain.Sedative use could alleviate pain in active phase.Women with mild labour pain have good delivery outcomes.

Objective To assess the level of environmental hormone (EH) in Lanzhou reach of the Yellow River and to find the pollutant sources and pollution routes. Methods Solid phase extraction (SPE), gas chromatography-mass spectrophotometry (GC-MS) and gas chromatography (GC-FID) were employed to determine EH in the water samples. Results 10 kinds of EH were detected, of which 6 were the priority control pollutants determined by the American EPA and 6 were predominant pollutants in China. 10 EH detected in Lanzhou reach of the Yellow River included naphthalene, phenanthrene, DBP, DEHP and benzothiazole and the detection rates of the five EH were 40%, 60%, 100%, 100% and 20% respectively. Conclusion The predominant environmental hormone pollutants in Lanzhou reach of the Yellow River are PAEs, PAHs, heterocycles, phenols and the main source of these pollutants is the waste water of petroleum chemical industry.

Objective To explore the acute effects of nickel in air PM2.5 on the cardiovascular system of rats.Methods The air PM2.5 of nickel-contaminated area and control area were collected and determined for some major metal elements.42 male Wistar rats were randomly divided into 10 groups,6 rats in each,the rats were instilled through trachea with saline,PM2.5 suspension of nickel-contaminated area and the control area respectively,at different doses(low,moderate and high dose).24 hours later,all the rats were killed for the determination of sVCAM-1 in the blood and MCP-1 in the myocardial tissue.Results The concentration of nickel in the air PM2.5 of nickel-contaminated area was found to be about 50 times higher than that in the control area.A good dose-response relationship was found in MCP-1 determination of the heart tissue in nickel-contaminated groups,and there were significant differences between nickel-contaminated area group and other groups(P﹤0.05).As for the sVCAM-1 in the serum,it was significant higher in the nickel-contaminated group and control group than the saline control group(P﹤0.05).Among the groups of nickel-contaminated area and control area,significant differences were found between the moderate and high dose groups.Conclusion The air PM2.5 from nickel-contaminated area has an obvious effect on the MCP-1 and sVCAM-1 of rats,the nickel in the air PM2.5 is likely the main contributing factor.

Objective To explore and analyze the curative effect of capecitabine in the treatment of advanced breast cancer and its influcing factors. Methods 100 cases of advanced breast cancer were selected,all patients were treated with combined or individual therapy, one period was 21-28 days, and the course of treatment was more than two cycles. Before and after treatment, the Eastern Cooperative Oncology Group (ECGO) score, receptor status, chemotherapy cycles, tumor metastasis and other factors of the data were collected and recorded. Results The short-term efficacy of the patients was: stable disease (SD) 39 cases, progressive disease (PD) 8 cases, complete remission (CR) 1 cases, partial remission (PR) 52 cases. 53.0%(53/100) for objective response rate (ORR), 92.0%(92/100) for disease control rate (DCR). All patients who received treatment from the end of the follow-up period were: 1 to 24 months, the median survival period was 6.5 months. The independent influencing factors of progress free survival (PFS) were the number of cycles of combination chemotherapy (P<0.05). During chemotherapy, the adverse reactions of patients was not much, respectively: 4 cases of hand foot syndrome, 2 cases of grade Ⅰ, 1 case of grade Ⅱ, 1 case of grade Ⅲ; 7 cases of gastrointestinal reaction, 4 cases of grade Ⅰ, 3 cases of grade Ⅱ; 3 cases of hematologic toxicity, 1 case of grade Ⅰ, 2 cases of grade Ⅱ. The lower ECGO score, ≥4 times of cycles of treatment, ER/PR+ improved the short-term efficacy(P<0.05), while the tumor metastasis and HER-2 receptor could not effect the short-term efficacy. Conclusion The short-term efficacy of capecitabine is related to ECGO score, receptor status and chemotherapy cycles, while has no relation with tumor metastasis and HER-2 receptor.

Cryptotanshinone (CPT)is a major fat-soluble ingre-dient in Salvia,which is a traditional blood-activating and stasis-dissolving drug.CPT has been gradually concerned,because it has a remarkable therapeutic effect on cardiovascular diseases, cancer and neurodegenerative diseases.A large number of exper-imental and clinical studies have shown that CPT can primarily inhibit tumor cell′s proliferation,angiogenesis,invasion and ad-hesion and induce apoptosis.Thus to some extent,it hinders in-vasion of tumor cell and prevents the distant metastasis.This pa-per focuses on the anti-tumor metastasis of CPT.

Objective To investigate the expression and distribution of aquaporin 3 (AQP3) in mouse early embryos at different stages.Methods Controlled ovarian hyperstimulation model of Kunming mouse was used to collect four-cell embryos,eight-cell embryos,morula stage,and early blastocysts.Immunofluorescence microscopy and laser confocal microscopy were used to detect expression and distribution of AQP3 channels in these stages.Results Fluorescence signal of AQP3 was found in four embryonic stages of mice.Distribution within embryo was different at different embryonic stages.AQP3 was mainly expressed on the karyotheca of blastomeres at four-cell and eight-cell stage.In morula stage,AQP3 was mainly expressed on cell membrane of each blastomere.In early blastocysts,AQP3 was predominantly expressed on the cell membrane and cytoplasm of trophoblastic cell.Conclusions AQP3 trans-membrane channel might have potential regulation function on mouse embryonic development.

Objective To assess the prevalence of the metabolic syndrome (MS) in Shanghai adults according to the criteria of the US National Cholesterol Education Programme Adult Treatment PanelⅢ ( NCEP ATP Ⅲ) definition. Methods Randomly selected adults were studied by means of stratified sampling. A cross-sectional study was conducted in Shanghai with a representative sample of 7 414 Chinese adults aged 35-74 years.Results Defined by the ATPⅢ criterion, the preliminary prevalence of MS was 19.81%. The prevalence of MS was 16.21% (95%CI 15.37%-17.05% ) after age was adjusted. The prevalence of MS was higher in female than in male (22.59% vs 16.64% ,P<0.01 ), and higher in urban than rural residents( 17.43% vs 17.16% ,P<0.01 ). The prevalence of MS increased with age in both male and female, especially in females aged above 55 years. There were 19.81% subjects with over 3 risk factors. The most common combination of four components in MS were central obesity, high triglyceridemia, low high-density lipoprotein-cholesterol and hypertension. Conclusions There is a high prevalence of MS in Shanghai adults. MS is increasingly becoming a noteworthy health problem. Early-diagnosis and integrated-methods of prevention and treatment of MS are mandatory.
