Objective · To investigate the prevalence of passive smoking among pregnant women in Shanghai and to analyze its influencing factors and to provide the basis and suggestion for making related intervention measures to reduce the harm of secondhand smoke on the health of pregnant women. Methods · From July to October 2014, pregnant women and their spouses were recruited for a questionnaire investigation at the antenatal care clinics of 3 maternity hospitals and 3 community hospitals in Shanghai. The questionnaire included demographic information, family basic situation and cognitive status of passive smoking. Results · The passive smoking rate before pregnancy in the 2831 pregnant women, who were involved in the investigation, was 17.1%. The passive rate during pregnancy was 7.8%. The difference between these two rates was statistically significant (P<0.05). 71.0% of the pregnant women have passive smoking for 15~59 min each day. Relative to home and work place, the passive smoking rate of pregnant women in public place was the highest (P<0.05). The passive smoking rate of pregnant women was significantly associated with the educational level of smoking spouses and the attitude of pregnant women when they faced the smokers. Conclusion · The passive smoking rate of pregnant women is influenced by the educational level of their spouses and the pregnant women's feedback to the smokers face to face. Public places are the most important exposure places to secondhand smoke for pregnant women. In order to reduce the harm from passive smoking to pregnant women and their fetuses, the related measures of smoking control at home education and smoking ban in public place should be made.

In 1989, Fitz defined and classified severe acute pancreatitis (SAP) and he thought that surgical treatment of SAP is feasible. Since then, the strategy of treating SAP was a controversial issue over past decades. Currently, relevant literatures reported that medical or minimally invasive treatments are superior to surgical treatment, while it is too early to make the final conclusion because of the complexity of SAP. From 1989 to 2008, 1852 patients with acute pancreatitis were treated at the General Hospital of PLA, and the clinical data of 18 patients who died of SAP were retrospectively analyzed. Based on the analysis, we concluded that medical conservative therapy and surgical operative therapy should not be opposed to each other. Selecting ideal timing and appropriate operation on the basis of pathological changes of retroperitoneum and pancreatitis should be considered seriously, and the new concept of "miniaturization of trauma" should also be introduced in treating SAP.

Objective To investigate the off-label use status in obstetrics ward so as to provide references for carrying out obstetrics pharmaceutical care and promoting safe medication use in pregnant and parturient women. Methods The prescriptions for pregnant and parturient women from January to June, 2015 in obstetrics ward were investigated. According to drug instructions, the off-label drug use of prescriptions of all selected patients was analyzed in the following aspects:the category of off-label drug use, and drugs use information. In addition, a logistic regression was conducted that modeled the odds of receiving an off-label prescription as a function of the following possible risk factors:pregnant, parturient women and the rank of doctors. The clinical results including the unreasonable drug application, abortion rate and birth defect were compared between the off-label drug use and on-label drug use groups. Results Total of 384 patients were selected, and 5330 prescriptions involving 50 drugs were analyzed. The rate of off-label drug use was 68. 5%, 27. 7% and 24. 0% in patients, prescriptions and drug categories, respectively. The main categories of off-label drug use were super solvent use ( 76. 6%) and indication (14. 3%). The top 3 drugs of off-label use were those for urinary and reproductive (56. 2%), alimentary tract (46. 9%) and traditional Chinese medicine (43. 4%). In addition, there was no significant correlation between the risk of off-label drug use and maternal status and the level of doctors. And no significant difference between the two groups in the unreasonable drug application, abortion rate and birth defect was detected. Conclusion The off-label drug use in obstetrics ward is common in this hospital and most of them are supported by clinical evidence. Due to the lack of more authoritative evidence-based medication, the doctors are suggested to use the drug according to provisions of the drug instructions. When off-label drug use is really needed, it should be based on the surpport of evidence basde medicine,so as to ensure the drug safety for pregnant and parturient women and avoid professional risks.

Objective To investigate the impact of 1,25(OH)2D3 on histological changes and activation of STAT3 in BLM?induced pulmonary fibrosis mice. Methods 30 male C57BL/6 mice were randomly divided into control group ,BLM group and BLM+VD group. Mice in BLM group and BLM+VD group received intratracheal injection of BLM(3 U/kg). Control group were intratracheally injected equal volume of sterile saline. From the first day after the surgery,mice in BLM+VD group received intraperitoneal injection of VD (5μg/kg·d). After 21 days, H&E and Masson′s trichrome staining were carried out. Aschroft score were used to evaluate histological changes in lungs. IL?6,IL?4 and INF?γin BALF were assessed by Elisa. p?STAT3,α?SMA and Collagen I were detected by western blot (WB) and immunohistochemistry. Results Fibrosis score and level of α?SMA,Collagen I in BLM group were significantly higher than that in control group (P < 0.05). However ,treatment with VD effectively at?tenuated fibrosis (P<0.05). IL?6 and IL?4 increased while INF?γwas decreased in BALF of BLM group (P<0.05). VD could ameliorate these changes. Upregulation and neuclear translocation of p?STAT3 were observed in BLM group,while VD intervention could inhibit phosphorylation of STAT3. Conclusions VD attenuate BLM?induced pulmonary fibrosis and regulate inflammatory cytokines probably by blocking STAT3 activation.
