Objective:To investigate the concentration of pulmonary surfactant-associated protein D ( SP-D) and interleukin-8 (IL-8) in the bronchoalveolar lavage fluid (BALF) of ACOS patients undergoing mechanical ventilation (MV). Methods:38 patients with ACOS undergoing MV were involved in the study. According to the APACHEⅡscore, the patients were divided into the remission group (n=20) and the aggravation group (n=18). BALF was collected on the 1st and 5th days after MV. The content of IL-8 and SP-D in BALF was measured by ELISA. The levels of IL-8 and SP-D in BALF of the patients with different severity were compared. Results:The level of SP-D was significantly higher on the 5th day than on the 1st day in the remission group,and it decreased more ob-viously in the worsening group (P<0. 05). The level of IL-8 decreased gradually in the remission group but increased gradually in the worsening group. The level of SP-D was negatively correlated with IL-8 level and APACHEⅡ score. Conclusion:The findings suggest that the levels of SP-D and IL-8 in BALF are correlated with prognosis of ACOS patients undergoing MV,and it may prove to be useful as a guidance of therapy and prognosis.

Objective To explore the application effect of action-oriented teaching method in senior midwifery practice teaching.Methods Selecting 30 students from class 1,grade 2011 of the midwifery professional for the experimental group,another 30 students from class 2 for the control group.We selected four core contents for the experimental teaching refbrm such as obstetric abdominal examination,external pelvimetry measurement,prenatal vulva washing disinfection and sterile towel covering before the delivery.The experimental group was taught by action-oriented teaching,in accordance with the procedures:putting forward the projects or work task,set goals and grouping,making work plans,implementing and evaluating.The control group was taught by traditional teaching.We used questionnaire smvey and skills examination to evaluate the teaching effects and conducted teaching satisfaction scores and scores for t test to two groups of students.Results (1)Questionnaires:The resuhs of the 18 issues on the teaching effect evaluation,professional technology level and nursing soft skills,etc.showed that the experimental group's evaluation of the action-oriented teaching is higher than the control group's evaluation of the traditional teaching(P＜0.05),action-oriented teaching is more helptul to improving the professional skill and nursing soft skills(P＜0.05).@The scores of skill examination:The skills scores of the experimental group(80.01 ± 9.36) were significantly higher than those of the control group(71.32 ± 8.85)(t=3.70,P=0.000).The difference was statistically significant (t=3.70,P=0.00).Conclusions Action-oriented teaching helps to raise practice teaching effecr,train students' clinical work ability and nursing soft skills.It is suitable for practice teaching of senior midwifery.

In order to study the character of periodontal ligament cells (PDLCs) attaching on commercially pure titanium (cpTi) by morphology and metrology on the early stage (24 h), 1 x 10(5)/ml PDLCs in 2 ml culture medium were seeded on cpTi discs fixed in 24-well culture plates. Morphology of cell attachment was observed by contrast phase microscope, scanning electron microscope (SEM) and fluroscence microscopy. Cell adhesion was analyzed by MTT at 0.5, 1, 2, 4 h respectively. PDLCs could attach and spread on cpTi discs. SEM showed that PDLCs had pseudopod-like protuberance. PDLCs showed different attaching phases and reached saturation in cell number at 2 h. It was concluded that PDLCs had good biocompatibility with cpTi, and showed a regular and dynamic pattern in the process of attaching to cpTi.

Objective To determine the role of c-Jun N-terminal kinase (JNK) signaling in annulus fibrosus cells response to interleukin (IL)-1. Methods Rat annulus fibrosus cells cultured in monolayer were exposed to IL-1, with or without JNK inhibition by SP600125. RNA was isolated for Real-Time polymerase chain reaction (PCR) after 24 h stimulation. Results IL-1 upregulation of mRNA for inducible nitric oxide synthase (iNOS), IL-6, cyclooxygenase (Cox)-2, matrix metalloproteinase (MMP)-3, MMP-13 were blunted by JNK inhibition, while downregulation of collagenⅠand insulin-like growth factor (IGF)-1 were also reversed by JNK inhibition. Conclusion JNK signaling inhibition can be a therapeutic target for blocking intervertebral disc degeneration induced by IL-1.

(1)H-NMR and (13)C-NMR assignments of 12-oleanene-3,11-dione (compound 1) were completely described for the first time through conventional 1D NMR and 2D shift-correlated NMR experiments using (1)H-(1)HCOSY, HMQC, HMBC techniques. Based on its NMR data, the assignments of 28-hydroxyolean-12-ene-3,11-dione (compound 2) were partially revised.

Objective To determine the prevalence of metabolic syndrome ( MS) in women who had gone through natural menopause, and to provide basic data for developing effective prevention and intervention of metabolic syndrome in Taixing area Jiangsu province. Methods A cluster sample of natural postmenopausal women aged 45 to 64 years were sampled and assessed by questionnaires, physical measurements, and biochemical tests; and analyzed according to the International Diabetes Federation ( IDF, 2005) diagnostic criteria for MS. Results The crude prevalence of metabolic syndrome was 35. 25% and the standardized prevalence rate was 31. 47% after age being adjusted. The prevalence of metabolic syndrome was increased with age ( P < 0. 01). The constituent ratio of the combinations of 3, 4, and 5 components in MS was 21. 45% , 10. 73% , and 3. 07% , respectively. Conclusion The prevalence of the metabolic syndrome among older women after menopause is high and increasing with aging. Public education should be strengthened to improve the quality of life in postmenopausal women and prevention and intervention should be adopted earlier as well.

Objective To systematically compare the efficacy of three-dimensional conformal radiotherapy (3D-CRT) versus intensity-modulated radiotherapy (IMRT) in the treatment of prostate cancer (PCa).Methods Clinical comparative studies of IMRT and 3D-CRT in the treatment of PCa were collected from PubMed, EMBASE, China National Knowledge Infrastructure (CNKI), and Wanfang Data after two independent researchers developed the strategy and inclusion and exclusion criteria for the literature search.Articles published up to February 2017 were searched for, and the languages of publications were restricted to English and Chinese.Clinical meta-analysis of the data from the relevant studies was performed using the RevMan5.3 software.Results A total of 15 relevant retrospective cohort studies were collected from the databases in strict accordance to the search strategy and inclusion and excluding criteria.There were 4608 PCa patients, including 2229 in the IMRT group and 2379 in the 3D-CRT group.IMRT and 3D-CRT had similar adverse effects in terms of early-stage (odds ratio[OR]=0.77, 95% confidence interval[CI]:0.43-1.40, P=0.390) and late-stage (OR=0.75, 95%CI:0.55-1.04, P=0.080) urinary tract injury.However, IMRT led to reduced early-stage (OR=0.47, 95%CI:0.27-0.82, P=0.008) and late-stage (OR=0.52, 95%CI:0.35-0.78, P=0.001) intestinal injury compared with 3D-CRT.Meanwhile, the biochemical recurrence-free survival rate was also significantly higher in the IMRT group than in the 3D-CRT group (OR=1.87, 95%CI:1.51-2.32, P=0.000).Conclusions IMRT is more protective against intestinal injury with a higher biochemical recurrence-free survival rate compared with 3D-CRT during the treatment of PCa.
