Objective To investigate the effect of standardized usage of antibiotics and hand hygiene on carbapenem-re-sistant Enterobacteriaceae (CRE) infection in neonates. Methods According to the situation of standardized management of an-tibiotics in our hospital, the study period, from January 2011 to December 2013, was divided into pre-intervention, transition and post-intervention. Retrospective study was employed to analyze the antibiotics use density (AUD), the hand hygiene compliance rate among the medical staff, the positive rate of CRE and the nosocomial infection percentage of the neonatology department. Results From pre-intervention to post-intervention period, the AUD was decreased from 12.93 DDDs to 8.10 DDDs;hand hy-giene compliance rate of medical staff was increased from 53.49%to 83.33%;the detection rate of CRE was decreased from 3.71%to 2.27%. The differences were all signiifcant among different periods (P<0.01). The nosocomial infection percentage decreased from 0.22%to 0.17%and there was no signiifcant difference (P=0.441). Conclusions Standardized usage of antibiotics and hand hygiene can be served as economical yet effective approaches to controlling CRE infection in neonates.

ObjectiveTo investigate the mental health of freshmen of university.MethodsSymptom Checklist 90 (SCL-90) was used to self evaluate 7763 freshmen of university in Ningbo.Results and ConclusionThe overall level of the mental health of this group was higher than that of the Chinese module, and the prevalence of psychological symptoms was 13.2%. The average level of mental health of female were inferior to male. The difference between the students from cities or towns and from the countryside were distinct. Students who were satisfied with their majority get noticeably higher average score than the ones who were not satisfied.

Objective To investigate the clinical characteristics of infectious diseases of CNS.Methods Inpatients treated in the second hospital of Hebei Medical University from 1996 to 2005 were subjected to retrospective study.Results During 10 years,the hospitalization number of infectious diseases of CNS was 3929.The proportion of inpatients with viral meningitis(encephalitis),cerebral cysticercosis,tuberculous meningitis(TBM),purulent meningitis(PM)and cryptococcal meningitis(CM) was 63.8%,17.4%,7.7%,0.7% respectively.The hospitalization number of viral meningitis (encephalitis),TBM,PM and CM in the 2001—2005 5-year period was 53.5%,21.3%,35.3%,and 77.3% higher than that of the 1996—2000 period.Whereas the hospitalization number of cerebral cysticercosis decreased by 32.4% than that of the last 5 years.The peak months of viral meningitis (encephalitis)in a year were July,August and September.The peak months of TBM in a year were April, May and June.The case fatality of viral meningitis(encephalitis),cerebral cysticercosis,TBM,PM and CM was 8.1%,6.9%,22.4%,12.9%,33.3% respectively.Conclusions In the past l0 years,the incidence of common infectious diseases of CNS has increased in Shijiazhuang except cerebral cysticercoids. Our vigilance should be improved and some effective measures should be adopted to keep away infectious diseases of CNS.

Objective To investigate the changes of lead,zinc,copper,iron and calcium in blood of chronic poisoned infantal mice.(Methods) Forty-eight 21 day-old kunzea mice were randomly divided into 4 groups,each having 12 mice.Distilled water group was as control group and other three lead acetate poisoning groups had a dose of 10,20,40 mg/kg,respectively.The poisoning was carried out by lavage once a day,and consecutively for 46 days.Eyeballs of mice were picked then for blood sampling,and BS trace element analysis grapher was used to determine level of lead,zinc,copper and iron.Level of calcium was measured by Dimentional-RXL auto-biochemistry analysis meter.Results The lead and zinc levels in poisoned mice blood were increased with increasing lead acetate level administration,while zinc level changed inversely with lead acetate level.Significant differences were shown among control group and poisoning groups in terms of lead(P0.05).Conclusion Lead posioning can lead to zinc decreasing and copper(increa)-sing,which suggests that zinc works as a poential antidote of lead poisoning.

Objective: To understand the relationship between mental health status and vision-related quality of life( VRQL ) of students with moderate and high myopia, and to provide basis for the optimization of VRQL. Methods: Using convenient sampling method, the 8-18 years old students with moderate and high myopia were selected from Sichuan, Chongqing and Zhejiang. The mental health status and VRQL of students with moderate and high myopia were evaluated with Hospital Anxiety and Depression Scale and Quality of Life Scale for Ametropia. The multiple linear regression model was used to analyze the influencing factors for VRQL. Results: A total of 360 questionnaires were sent out and 354 were effectively recovered, with an effective rate of 98.33%. There were 116 ( 32.77% ) boys and 238 ( 67.23% ) girls; the median age was 16.65 years old. There were 211 ( 59.60% ) cases of moderate myopia and 143 (40.40%) cases of high myopia.There were 141 ( 39.83% ) found to be anxious and 176 ( 49.72% ) depressed. The median score of Quality of Life Scale for Ametropia was 64. The results of multiple linear regression analysis showed that sex ( β＇= -0.179 ), diopter ( β＇= 0.208 ), eyesight with glasses ( β＇= -0.229 ) and anxiety ( β＇= 0.439 ) were influencing factors for VRQL. Conclusion The mental health problems of the students with medium and high myopia are prominent; anxiety has a significant impact on the VRQL of the students.

Objective To determine the clinical characteristics and management of ovarian tumor in infertility women.Methods During the period from Jan.1 1999 to Dec.31 2004,110 infertility women with ovarian tumor were analysed retrospectively,in terms of clinical and pathological features.According to the histological findings,the tumors were divided into three groups:epithelial tumor,teratoma and others. Results Among 110 cases,49 cases were epithelial tumor,42 cases were teratoma,and 19 cases were others.A total of 97 cases were small ovarian tumor,and the maximal diameter was less than 5 cm.In epithelial tumor group only 29% were diagnosed before operation,significantly lower than the other two groups(P

Objective To explore the expression of high selective A receptor of endothelin-1 (ETA-R) in melanocytes from normal human beings. Methods Normal human melanocytes were cultured and mR-NA expression of ETA-R in melanocytes was measured by reverse transcription-polymerase chain reaction. Results The mRNA expression of ETA-R was seen in melanocytes. Conclusion This study combined with other experiments suggests that endothelin-1 may affect melanocytes by high selective ETA-R which may con-tribute to the pathogenesis of vitiligo.
