OBJECTIVE To survey the status quo of hospital infection management and countermeasures in township health center. METHODS To adopt a unified examination and assessment survey,the township hospital infection management,including organization,personnel training,monitoring,disinfection and isolation,occupational protection,sterile disposable medical supplies and medical waste management was investigated in 15 Lanxi Town ship Health Centers. RESULTS Only 2 centers had management organizations (13.33%),5 (33.33%) to participate in personnel/training,no one carry out the monitoring of hospital infection,with fuzzy concept about cleaning disinfection and sterilization and poor awareness of occupational protection. CONCLUSIONS Realizing a sound organization improving hospital infection management staff and intensive training,increaseing the investment and strengthening th supervision and inspection are in accordance with the law and guide management of patients in rural areas to be assured of a secure medical establishment.

Diffuse large B-cell lymphoma (DLBCL) is a heterogeneous group of non-Hodgkin's lymphoma.An uncommon subset with myc and either bcl-2 or bcl-6 rearrangement,also known as ‘double-hit’ lymphomas,is considered very aggressive clinical course and poor prognosis despite high-intensity chemotherapy.Recently,these lymphomas have received increased attention.This review explores the existing literatures for the involved genes with their functions,clinical features,diagnosis and treatment.

Objective:In order to improve operator’s cognitive level for standardized disinfection, this paper will focus on analyzing and interpreting the disinfection procedures for some common dialysis machines.Methods: This paper will interpret and compare the disinfection procedures for three brands of dialysis machines in the following aspects: the choice of the disinfectant, the disinfection method, the concentration of the disinfectant and the injected volume of the disinfectant, etc.Results: The procedures of hot disinfection with citric acid were used completely in those three brands of dialysis machine, and the procedure of sodium hypochlorite need been used periodically to remove the proteins and other organic matter.Conclusion:Although the dialysis machines provide almost complete and efficient disinfection procedures, but the operator should need to select the most suitable procedures according to their practical situation. If the operators cannot master the disinfection procedures and have not noticed the importance of it, the wrong operator will lead to incomplete disinfection, affect the normal operation of the dialysis machines and increase the risk of cross-infection.

Objective To evaluate the effect of ultrasonic speckle technique on cardiac function in patients with acute myocardial infarction (AMI).Methods 30 patients with AMI were selected as observation group,30 healthy people were selected as control group,and they were all detected by ultrasonic speckle technique.The differences of measurement indices of cardiac function with ultrasonic speckle technique were compared between the observation group and control group.The difference between ultrasonic speckle technique and its measured value was observed with single photon emission computed tomography(SPECT) as the gold standard.The correlation between the results of three-dimensional speckle ultrasound and SPECT in patients with AMI was analyzed.Results The parameters of LVEDV [(62.2 ± 6.4) mL vs.(80.3 ± 7.5) mL],LVESV [(21.7 ± 5.6) mL vs.(35.4 ± 7.2) mL] and LVEF [(62.6 ± 5.9)％ vs.(72.8 ± 5.6)％] in the observation group were significantly lower than those in the control group,the IVSTd [(1.1 ± 0.2) cm vs.(0.9 ± 0.2) cm] and LVPWd [(1.2 ± 0.2) cm vs.(0.8 ± 0.1) cm] were significantly higher than those in the control group,the differences were statistically significant(t =8.431,9.865,3.651,8.798,6.654,all P ＜ 0.05).In AMI patients,there were no significant differences in left ventricular parameters LVEDV,LVESV,LVEF measured between ultrasonic speckle technique and SPECT(all P ＞ 0.05).With SPECT as the gold standard,in AMI patients,the ultrasound parameters LVEDV,LVESV and LVEF were positively correlated with SPECT parameters(r =0.912,0.903,0.899,all P ＜ 0.05).Conclusion Ultrasound speckle technique can well evaluate myocardial function in patients with myocardial infarction.

OBJECTIVE: Recent studies of mental health status in undergraduates are reviewed by literatures in mental health standard, measurement and influential factors. It is aimed to analyze the current status of mental health in undergraduates and provide references for related research of mental health, psychological counseling and psychological health in undergraduates. DATA SOURCES: The China Journal Full-text Database (CJFD) and Wanfang database were undertaken to id entify related articles published from January 1995 to August 2005 with the key words of "psyche of undergraduate, mental health, health standard" in Chinese. References of retrieved articles were searched. Mental health related books were retrieved such as Health Psychology, Psychic Health Measurement and so on.STUDY SELECTION: The data were selected primarily, and related articles of mental health standard, measurement and influential factors were included. Studies unrelated to undergraduates were screened out, and fulltexts of the other literatures were looked up.DATA EXTRACTION: A total of 40 articles of mental health standard,measurement and influential factors in undergraduates were selected, of which 17 articles accorded with topic and content were collected. There were 4 articles of mental health standard, 6 literatures (listing 6 types and 20 kinds of questionnaires and tests) of measurement and 7 literatures (6articles) of influential factors.DATA SYNTHESIS: Main content of mental health was intellective health, emotional health and spiritual health. ①No mental health standard was authorized and generally accepted in internal and external studies at present. The four signs of mental health designed by World Psychiatric Association (WPA) were praised and identified, which were harmony of body,intelligence and emotion; adaptation of the environment and modesty in each other; well-being; bringing ones ability into full play and living effective living. Mental health standard of Chinese undergraduates was composed of normal cognition, good emotion, perfect personality, coordinated interpersonal relation and appropriate self-consciousness. ②Present commonly used-mental health measurement for undergraduates was various, but there still was some disadvantage. Big Five Questionnaire (BFQ) and University Personality Inventory (UPI) were commonly used at abroad. Symptom Checklist-90 (SCL-90) was commonly used at home. ③Major factors influencing mental health of undergraduates were family, environment, age,sex, school, subject, religion and so on, and speciality had obvious effect on mental health of undergraduates.CONCLUSION: The importance of mental health of undergraduates is realized gradually by scholars, and more and more scholars at home and abroad study the mental health of undergraduates. How to design exact mental health standard and precise mental health measurement for undergraduates deserve further investigation. Meanwhile, it is necessary to deeply analyze the correlation between speciality and mental health of undergraduates.Fan BB, Zhang CH.Standard and evaluation of mental health in undergraduates.
