Objective To monitor Staphylococcus infection in a hospital,and trace the source of Staphylococcus isolated from infectious wound-related hospital environment by molecular analysis. Methods By combination of fluorescence quanti-tative polymerase chain reaction (FQ-PCR)and culture method,environmental specimens related to 5 patients with wound infection were taken and performed multilocus sequence and MecA gene typing analysis. Results A total of 71 environmen-tal specimens were taken,Staphylococcus accounted for 36.62% (n= 26),88.46% (23/26 )of which were MecA+ methi-cillin-resistant strains. 77.78% (7/9)of Staphylococcus aureus (S. aureus)and 95.00% (19/20)of coagulase negative Staphylococcus (CNS)were methicillin-resistant strains. Multilocus sequence analysis revealed that ST239 (n= 6)was the most common sequence type in S. aureus;Staphylococcal cassette chromosome mec (SCCmec)analysis showed that the ma-jor type of S. aureus was typeⅢ,and CNS were typeⅢandⅣ. Conclusion Staphylococcus is common in healthcare-associated infection,and most Staphylococcus are multidrug-resistant,continuous monitor on drug-resistant Staph-ylococcus is necessary,and risk of Staphylococcus variant to medical institutes need to be paid attention.

To better understand the current status of medical students in clinical medical ethics,we design the relevant questionnaire,with 468 medical students conducting a questionnaire survey.Findings in general are more satisfactory.but there are great differences on certain issues.Educational Strategies:medical education curriculum should open more humanities courses and post-clinical teachers should pay close attention to ethics education for medical students.

Objective:To explore the effect of the labor abdominal pressure training device on the second stage of labor and the outcome of labor in primiparas undergoing epidural analgesia.Methods:The healthy primiparas who had patient controlled epidural analgesia were randomly divided into the observation group (126 cases) and the control group (122 cases). The control group used conventional oral instruction to force after entering the second stage of labor. The women in the observation group used the labor abdominal pressure training device to guide the force. The time required to learn to exert force, the second stage of labor and the outcome of labor were observed.Results:The parturient women learned the correct time to exert force, the time of the second stage of labor, the self-efficacy score of the second stage of labor, and the post-natal fatigue score were (13.56 ± 5.32) min, (76.32 ± 10.58) min, (121.38 ± 17.52)points, (8.56 ± 0.72) points in the observation group, and (25.47 ± 7.65) min, (105.21 ± 18.41) min, (101.42 ± 14.32) points, (13.31 ± 0.46) points in the control group, the differences between the two groups were statistically significant ( t values were -10.326-11.002, all P<0.05). The maternal spontaneous delivery rate, fetal assisted delivery rate, forceps assisted delivery rate, perineal lateral cut rate, perineal median cut rate, perineal tear>Ⅰ°rate were 94.44% (119/126), 4.76% (6/126), 0.79% (1/126), 9.52% (12/126), 11.11% (14/126), 6.35% (8/126) in the observation group, and 85.25% (104/122), 12.30% (15/122), 2.46% (3/122), 29.51% (36/122), 4.10% (5/122), 9.84% (12/122) in the control group,the differences between the two groups were statistically significant ( χ2 values were 4.582-9.437, P<0.05 or 0.01). Conclusions:The use of an abdominal pressure training device for labor in patient controlled epidural analgesia for pregnant women can shorten the second stage of labor and study the time of exertion, improve the self-efficacy of the second stage of labor, reduce the degree of perineal injury and fatigue, reduce the vaginal birth rate, and help protect Mother and child are safe.

Objective To explore the expression of galectin-3 in human gastric carcinoma tissues and to investigate its clinincal significances.Methods Immunohistochemistry method was used to detect the expression of galectin-3 in 52 pairs of specimens of gastric carcinoma tissues,33 atypical hypcrplasia of gastric tissues and 20 gastritis tissues.Expression levels of galectin-3 in different tissues were compared and analyzed.The relationship between expression levels and clinical parameters was investigated.Results The positive rates of galectin-3 were 94.2 ％ (49/52),80.0 ％ (16/20) and 33.3 ％ (11/30).The positive rates of galectin-3 were higher in gastric carcinoma than those in atypical hyperplasia and gastritis (Z =2.181,6.160,3.611,all P ＜ 0.05).The expression levels of galectin-3 in lymph node metastasis gastric carcinoma,poorly differentiated gastric carcinoma were 100 ％ (22/22),100 ％ (45/45) respectively.Galectin-3 expression in patients without lymph node metastasis,high differentiation in gastric carcinoma were 78.6 ％ (27/30),57.1％ (4/7)respectively.The expression levels of galectin-3 were correlated with metastasis and differentiation,with higher expressions in the cases with metastatic lymph nodes (Z =12.463,P ＜ 0.05) and in poor differentiation tissues (Z =3.245,P ＜ 0.05).Conclusion Galectin-3 is overexpressed in gastric carcinoma tissues,indicating that both of them may play roles in the pathogenesis of gastric carcinoma.The overexpression of galectin-3 is correlated with metastatic lymph nodes and poor differentiation,indicating that galectin-3 may be prognostic indicator of gastric carcinoma.

1-(2,6-Dimethylphenoxy)-2-(3,4-dimethoxyphenylethylamino) propane hydrochloride(DDPH) caused parallel rightward shifts of the phenylephrine(Phe) concentration-contractile response curves and did not suppress the maximal contractile response to Phe (pA2=7.24) in isolated rabbit urinary bladder smooth muscle. DDPH decreased the parameters of cystometry in urethane-anesthetized rats. Thirty minutes after DDPH (25 and 50 mg*kg-1 ig) administration, bladder capacity, voiding pressure, voiding threshold pressure were significantly decreased. With the observation of light-microscope and electron-microscope technique, DDPH (25 and 50 mg*kg-1*d-1 ig for 4 weeks) also inhibited the development of testosterone propionate-induced benign prostatic hyperplasia in rats. The results indicate that DDPH may inhibit benign prostatic hyperplasia and improve the urinary flow.
