Objective To evaluate the correlations of serum cardiac troponin T and serum uric acid levels in in aged patients with chronic congestive heart failure(CHF) and the effect of cardiac troponin T(cTnT) on the prognosis of the CHF. Methods 200 cases of congestive heart failure patients(Cardiac function NYHA class Ⅰ-Ⅳ) were enrolled for retrospective analysis and divided into four groups ,50 cases per group;randomly picked 50 cases of pantients with cardiac function NYHA class Ⅰ as a control group; and analyzed the relationship of serum uric (UA) and cTnT level and the occurrence of CHF. All the patients were arranged into normal group and higher group according to cTnT concentration. Cardiac events, including repeated or aggravated heart failure or cardiac death,in patients with increased cTnT during hospitalization were compared to those without it. Results In congestive heart failure group (Cardiac function NYHA class Ⅱ-Ⅳ) ,the cTnT and UA contents increased significantly than that in control group.Incidence of cardiac events was higher in patients with increased cTnT than without it (P ＜ 0.05). Conclusion The heavier the congestive heart failure, the blood uric acid and troponin T were more elevated, so they were closely linked with congestive heart failure, and were the factor for onset of congestive heart failure, and could be combined to evaluate the severity of heart failure in aged patients. The cTnT could predict the prognosis of the old patients with CHF.

BACKGROUND: Mental health is the most important internal resource that individual can depend on and also an important factor which affects the existence and development of individual. But there are few studies on the level and characteristics of mental health of female prisoners during serving a sentence.OBJECTIVE: To investigate the level and characteristics of mental health of the female prisoners in Shandong Province.DESIGN: Retrospective, cross sectional,multi-variable and sampling survey based on female prisoners.SETTING: Department of Technology in Shandong Police College.PARTICIPANTS: The investigation was completed in the Shandong Police College frotm January 2002 to March 2002.Totally 393 female prisoners from the Shandong Female Prison were selected with the grouping-sampling method to give the questionnaire and attend the investigation voluntarily,and the persons with definite mental disease were excluded.METHODS: The mental health items of female prisoners,including 9 factors such as somatization, obsessive-compulsion,sensitivity of human relations, depression, anxiety, hostility, phobia anxiety, paranoid ideation and psychosis,were explored with Symptom Checklist 90(SCL-90), and the judging standard of psychologic obstacle was whether the total scores of positive symptoms were 2 standard deviations more than those of the norm or not.And combined with the archives of the female prisoners and the questionnaire of self-editing item,relative data were collected. The uniform instructional words and the methods of filling in were explained to the female prisoners firstly,and then the answers of the questionnaire were written collectively.MAIN OUTCOME MEASURES: The mental health level and the psychological characteristics of female prisoners.RESULTS: 393 questionnaires were provided.There were 15 questionnaires excluded because more than 5 questions were missed in the paper or responsion consistency deviation appeared obviously after callback.378questionnaires were valid ,and the effective rate was 96.2%. ①The item numbers of positive reaction,total average score,toatal average score of positive symptoms of SCL of the prisoners were higher respectively than those of the norm of general group and reached the most significant level.The psychological problems of different degrees were widespread among them.②There were 372 female prisoners who had positive symptoms, and the detection rate was 98.41% ,which was more than that of positive symptoms in prisoners (40.6%).The significance of difference existed(x2=503.59,P ＜ 0.001).There were 84 persons who had psychologic obstacle in the female prisoners,and the detection rate was 22.2%,which was higher than that of in the general group (10.54%).The significance of difference existed (x2=54.128,P ＜ 0.001). ③The scores of 9 factors of SCL were all higher in the female prisoners than in the adult norm of the country,and reached the most significant degree. It showed that the obvious abnormality existed in the somatization, obsessive-compulsion, sensitivity of human relations, depression, anxiety, hostility, phobia anxiety,paranoid ideation and psychosis of the tested persons, and the ordering of them was sensitivity of human relations ＞hostility ＞obsessive obsessivecompulsion ＞depression ＞somatization ＞anxiety ＞phobia anxiety/paranoid ideation＞psychosis. Among the 9 factors,the average scores of obsessivecompulsion, sensitivity of human relations, depression,and hostility were greater than 2,and the symptomatic reaction of them was already above moderate. ④The detection rates of psychological problem or psychologic obstacle of the factors such as paranoid ideation, hostility, somatization,sensitivity of human relations and anxiety,etc.were higher,which indicated that these were the main psychological deviation contents.CONCLUNSION: Compared with the general group,the total level of mental health of female prisoners is lower, and the detection rate of psychologic obstacle and the degree of symptomatic reaction are obviously higher,and the psychological characteristics such as phobia anxiety, obsessive-compulsion,sensitive-suspiciousness, depression and hostility,etc are outstanding.

BACKGROUND: Every year there are case reports about freshmen who took extreme actions because of maladaptation. Freshmen's mental health is related not only to their adaptability to university life but also to the stability and harmony of university campus.OBJECTIVE: To investigate the level of freshmen's mental health in early university life and screen out the students with severe psychological problems.DESIGN: A cross-sectional study.SETTING: Department of Education, Shaoxing University of Zhejiang Province.PARTICIPANTS: A total of 4 417 freshmen of year 2003 from Shaoxing University were selected as observational subjects during November 2003.METHODS: The status of mental health was surveyed with symptom checklist-90 (SCL-90), self-rated anxiety scale (SAS), and self-rated depression scale (SDS). SCL-90 consisted of 9 dimensions: somatization, obsessive-compulsive, interpersonal sensitivity, depression, anxiety, hostility,phobic anxiety, paranoid ideation and psychoticism, and 5 evaluation scales: 1 as none, 2 as mild, 3 as moderate, 4 as severe and 5 as rather severe. The higher the score, the lower the level of psychological health was. They were evaluated as whether they had problem of psychological health or not. SAS contained 4 grades that recorded mainly the frequency of the appearing symptoms defined by the evaluation entry. The standard score took 50 points as the critical point. The higher the score, the more severe anxiety status was. The main statistical index of SDS was the exponent of depression severity that ranged from 0.25 to 1.00. Those with less than 0.05 had no depression, 0.50-0.59 mild depression, 0.60-0.69moderate depression, and above 0.70 severe depression. The group test was conducted among the freshmen 3 months after they entered the university.MAIN OUTCOME MEASURES: The scores of SCL-90, SAS and SDS.RESULTS: A total of 4 417 questionnaires were sent out, and 4 387questionnaires were collected with the effective rate of 99.32%. ① The scores on obsessive-compulsive, phobic anxiety and psychoticism ih the freshmen were higher than those of the norms (t=2.88-4.82, P ＜ 0.01). Among them, 333 freshmen with common psychological problems were detected, which constituted 7.59%. Another 49 students with severe psychological problems were screened out, which made up 1.12%. ② There were significant sex differences of scores in SCL-90 factors between boys and girls (total average t=5.56, P ＜ 0.01). ③ There was a significant correlation of depression and anxiety of SCL-90 scores with the standard scores of SDS and SAS, respectively, and the coefficient of product-moment correlation was 0.532 and 0.361, respectively.CONCLUSION: ① The freshmen did not have good psychological health.② The girls had more psychological problems than the boys. ③ The scores on depression and anxiety of SCL-90 were mutual proof with the standard scores of SDS and SAS, respectively.

Objective To investigate the distribution and antimicrobial resistance of pathogens causing diabetic foot ulcer(DFU). Methods Secretion specimens of DFU in patients at several hospitals in Qingdao were collected and performed bacterial culture and antimicrobial susceptibility testing. Results A total of 216 pathogens were ob-tained from 137 patients with DFU. Isolation rate of gram-negative bacilli,gram-positive cocci and fungi was 58.80% (n= 127),39.81% (n= 86)and 1.39% (n= 3)respectively. 76 (55.47% )patients were infected with sin-gle pathogen,61 (44.53% )were infected with mixed pathogens;the top five detected pathogens were Pseudomonas aeruginosa(n= 37),Staphylococcusaureus (n= 35),Escherichiacoli (n= 26),Staphylococcusepidermidis(n=24),and Acinetobacterbaumannii(n= 22). The resistance of Enterobacteriaceae to amikacin,amoxicillin/clavu-lanic acid,cefoxitin,imipenem,piperacillin/tazobactam,ticarcillin/clavulanic acid were 0-16.67% ;the resist-ance of Pseudomonas aeruginosa to imipenem,tobramycin,amikacin,cefepime,gentamicin,and quinolones were 2 .70% -1 8 .92% ;the resistance of Acinetobacterbaumannii to imipenem and levofloxacin were low,but to the other antimicrobial agents were all above 30% . Conclusion The major pathogens from DFU were gram-negative bacilli, the next were gram-positive cocci,antimicrobial resistance patterns of each species are quite different,clinicians should choose antimicrobial agents according to antimicrobial susceptibility testing results.
