Objective To explore relativity between serum cortisol and post-stroke depression in old patients with stroke. Methods Serum cortisols of 41 stroke patients were examined two weeks after stroke, and they were all assessed through Hamilton Depression Scale and then happening rates of post-stroke depression observed in both normal cortisol group and enhanced cortisol group were tested through χ2 test. Meanwhile relativity between serum cortisol level and post-stroke depression were analysised. Results Happening rates of post-stroke depression had an evidently difference between both normal cortisol group and enhanced cortisol group(χ2=4.11;P <0.05). Mark of normal cortisol group was 15.29±7.28, enhanced cortisol group was 25.85±10.81, both groups had an evidently difference( P <0.01). Serum cortisols were not obviously relative to depression degree in normal cortisol group( r =0.295;P =0.194) while they were obviously relative in enhanced cortisol group( r =0.702;P =0.001). Conclusion Enhanced cortisol could forecast higher possibility of depression after the old post-stroke, and detecting cortisol could offer theory foundation for prevention and cure of post-stroke depression.

Objective To investigate the effects of different hemostatic methods in laparoscopic ovarian cystectomy on ovary functions . Methods A total of 90 cases of laparoscopic ovarian cyst resection from June 2010 to June 2013 were selected .They were divided into bipolar electrocoagulation group , monopolar electrocoagulation group , and suture group according to the doctor ’ s favor.The FSH, LH, and E2 before and after surgery were compared among the three groups . Results All patients were followed up for more than 1 year.The rate of patients with menstrual disorder in monopolar electrocoagulation group [33.3%(10/30)] was significantly higher than that in bipolar coagulation group [10.0%(3/30),χ2 =4.812,P=0.028] and suture group [6.7%(2/30),χ2 =6.667,P=0.010].There was no significant difference between bipolar premature coagulation group and suture group (χ2 =0.000, P=1.000).There was no significant difference in FSH ,LH,and E2 among the three groups before and 1 month after surgery (P>0.05).There was no significant difference in FSH ,LH, E2 between bipolar premature coagulation group and suture group 6 months after surgery (P>0.05).In the monopolar electrocoagulation group , the FSH [(10.43 ±2.04) U/L] and LH [(18.58 ± 3.82) U/L] levels were significantly higher than those in the bipolar electrocoagulation group [(8.12 ±1.82) U/L and (13.31 ± 2.53) U/L, P<0.05], and in the suture group [(7.08 ±1.68) U/L and (12.61 ±2.68) U/L, P<0.05].The E2 level in the monopolar electrocoagulation group [(252.5 ±26.9) pmol/L] was significantly lower than that in the bipolar electrocoagulation group [(321.3 ±28.2) pmol/L, P<0.05] and in the suture group [(313.7 ±31.4) pmol/L, P<0.05]. Conclusion In laparoscopic ovarian cystectomy , bipolar coagulation hemostasis is safer than monopolar electrocoagulation hemostasis , being worthy of clinical application .

Objective To get a view of the participation, motivation and barrier of voluntary activities in medical graduates, and to provide valuable advices for improving such behaviors. Methods The convenience sample method was used in medical graduates in 2014 and the total sample was 348. The data of voluntary service were collected by self-designed questionnaire, including whether partici-pating in voluntary service, times, types, motivations and barriers. SPSS 20.0 were used in statistic analysis and data were processed by description analysis and χ2 test. Results The effective response rate is 80.7%(281). The proportion of the post graduated students participation in voluntary activities is 65.8%(185), however, only 13.4%(28) claimed such activities more than 3 times. The proportion of participation in male, student leaders and party members were higher than those female, non-student leaders and non-party members, the different is statistically significant (P<0.05). The proportion of medical related voluntary activities is 52.6%. The primary motivation of voluntary behaviors is social responsibility (30.1%), while the primary obstacle is lack of medium (39.50%)and limitation of personal time and energy (30.0%). Conclusions The participation and persistence of voluntary activity in graduated students are not high enough. The colleges need to strength the organization and management of voluntary activities and focus on social responsible education, inspire and guide the postgradu ate students to participate in voluntary activities persistently by using their specialties.

Hemoperitoneum is not uncommon in patients receiving peritoneal dialysis (PD)be-cause the PD catheter provides a window to the peritoneum.Gynecological associated phenomena account for the majority of cases.Intra-abdominal pathology of solid organs such as the kidney,liver,and spleen as well as the gastrointestinal tract is recognized.Unique to PD patients,hemoperitoneum may be associated with the catheter itself,uremic bleeding,or peritonitis.The choice of treatment depends largely on the cau-ses of hemorrhage.This paper reviews hemoperitoneum in adult PD patients.

OBJECTIVE:To study the change of antibacterial resistance spectra of3non-fermental G - bacteria in our hospital during recent4years,so as to guide the rational use of antibacterial.METHODS:Pseudomonas aeruginosa,acineto?bacter baumanii,stenotrophomonas maltophilia were isolated from clinical samples in our hospital from July2001to June2005,the susceptibility of these isolates were tested by Kirby-Bauer agar diffusion method,data were analyzed by WHONET5.RESULTS:598strains of P.aeruginosa,281strains of A.baumanii and209strains of S.maltophilia were obtained during4years.Now the resistance rates of ceftazidime,amikacin,cefoperazone/sulbactam and imipenem to P.aeruginosa were lower than30%;A.baumanii were sensitive to imipenem,the other antibiotic resistance rates were more than50%;The antibiotic resistance rate of S.maltophilia to ofloxacin and trimethoprim/sulfamethoxazole was relatively low?er.CONCLUSIONS:The antibiotic resistance rates of non-fermental G - bacteria are high and display multiple-resistant.It's important to monitor the antibiotic resistance periodically to guide clinical antibiotics use.

Objective To reproduce a rabbit model of alginate immune pneumonia, and to study the pathogenic role of alginate on lung tissue. Methods Rabbits of group A, being challenged by saline, served as the control group. Rabbits of group B and C were immunized with seaweed alginate and bacterial alginate respectively. Body temperature,peripheral blood cells and the serum level of circulating immune complex (CIC) were measured after the challenge. Bronchoalveolar lavage fluid (BALF) specimens were incubated and bacterial colonies were counted. The cell number and differential count of BALF were made. The pathological changes of the lung tissue were observed under microscopy. Results In both seaweed alginate and bacterial alginate groups, the peripheral blood cell count and the number of bacterial colonies in BALF were similar to that of the saline group. However, the serum CIC levels and the cell count of BALF were increased significantly after the challenge. Under light microscopy, lymphocyte infiltration and lymphoid follicle formation around the bronchiolus were found in all alginate immunized groups, and there was also narrowing of bronchioli. Conclusion Both seaweed alginate and bacterial alginate could be used to establish the model of alginate immune pneumonia in rabbits. Alginate can cause inflammatory reaction and pathological changes in the rabbit lung, manifesting mainly peribronchilar lymphocytic infiltration and lymphoid follicle formation around the bronchioli.
