OBJECTIVE To explore the incidence of the nosocomial infection in patients with mental diseases,(analyze) the correlative factors and then reduce the incidence.(METHODS) By using the retrospective method,the(inpatient) cases in psychiatry department from Jan 2000 to Dec 2004 were surveyed and statistically analyzed.(RESULTS) There were 313 cases of nosocomial infection from 9 089 inpatients with mental diseases.The infection rate was(3.44%.) The total rate had been dropped year by year.The major sites of the infection were the(upper)(respiratory) tract(34.82%),the gastrointestinal tract(20.45%) and the urinary system(18.53%).The(infection) rate in ladies patient area(3.83%) was significantly higher than that of gentlemen patient area(3.07%)(P

After the advantages of PACS system in medical imaging examination were described, its rational appli-cation in medical imaging examination was elaborated .

· AIM: To study the expression of basic fibroblast growth factor (bFGF) receptor protein in human lens epithelial cells (HLECs). METHODS: Immunohistochemistry was used to detect the level of bFGF receptor protein and image analysis was adopted to perform the relative quantitative analysis on it. · RESULTS: There was bFGF receptor protein in HLECs accordingl to both qualitative and quantitative analysis. · CONCLUSION: bFGF receptor protein exists in HLECs and it is the material foundation for bFGF to improve the proliferation of HLECs.

Blood-brain barrier is a natural protection for human body. It protects central nervous system from the interruption and damage of xenobiotics. However, it prevents potential drugs aimed at central nervous system, thus becomes an obstruction for the development of central nervous system drugs. The recent development of blood-brain barrier permeability research and several lead optimization strategies to improve blood-brain barrier permeability are reviewed. These structure optimization methods include increasing lipophilicity, reducing hydrogen bond doners, simplifying molecule, increasing rigidity, lowering polar surface area, avoiding acid group, prodrug strategy, modifying into active transporter's substrates, as well as avoiding P-glycoprotein recognized structures.

AIM: To study the effects of different dose proportioning the danggui-shaoyao powder (DS) on learning and memory and the content of NO in brain in mice. METHODS: The ability of learning and memory was measured by the step-through task and the water maze task. The content of NO in brain was determined referring to the reagent manual. RESULTS: All different dose proportion of DS promoted the memory of normal mice. And only DS 1 (1 5.4) and DS 3 (1 1.34) obviously improved the scopolamine-induced mice passive avoidance handicap, prolonged the latency, and decreased number of errors. DS 3(1 1.34) obviously improved reserpine-induced mice spatial orientation handicap and prolonged the latency; others had no remarkable effect on spatial orientation handicap of mice. And all different dose proportions of DS could reduce the content of NO in the brain of passive avoidance disruption mice induced by scopolamine. CONCLUSION: DS 3 (1 1.34) improves passive avoidance handicap and spatial orientation handicap of mice, and reduced the content of NO in the brain of passive avoidance handicap mice induced by scopolamine. The effect of DS 3(1 1.34) is the best on benefiting memory.

Objective To investigate the function and possible mechanism of acupuncturing “Zusanli” point on the liver cell membrane of rat with chronic alcohol liver injury. Methods Chronic alcoholic liver damage rat model was established by 60% ethanal intragastric infusion for 60 d. Total phosphatide, total cholesterol and phosphatide component were determined. Result Compare with the normal recovery group, acupuncture “Zusanli” point can increase the content of PC and PE, decrease the content of Chol and SM of liver cell, and reduce the membrane aging index C/P, SM /PC. Conclusion Acupuncture “Zusanli” point has the function of protecting the liver cell membranes and improving the liver cell membrane’s fluidity of chronic alcohol liver injury rat.

Objective To investigate the inherited tendency of lateral discoid meniscus of the knee, and to evaluate the surgical efficacy for the disease in two consecutive generations. Methods There were 12 cases of lateral discoid meniscus, which were confirmed by arthroscopy, in 6 families. Arthroscopic total or partial meniscectomy or meniscoplasty were carried out in these cases. Results In concordance with the Watanabe’s classification, 9 cases were classified as “type Ⅰ” and 3 cases,“type Ⅱ”. Two cases underwent total meniscectomy, 3 cases received partial meniscectomy, and 7 cases, meniscoplasty. The results of surgery were assessed in accordance with the Ikeuchi criteria as follows: good in 3 cases, fair in 2 and poor in 1 in the first generation, while excellent in 5 and good in 1 in the second generation. Conclusions There may be a hereditary predisposition to discoid meniscus.

Objective To understand the occurrence and risk factors of healthcare-associated infection(HAI) in a neonatal intensive care unit(NICU).Methods Neonates who were admitted to the NICU of a hospital from January 2012 to December 2014 were investigated retrospectively,risk factors for HAI were performed univariate analysis.Results A total of 760 neonates were included in the investigation,198 neonates developed 259 times of HAI,incidence of HAI was 26.05％,case incidence of HAI was 34.08％,incidence of HAI per 1 000 patient days was 9.50‰;the main infection site was lower respiratory tract (n =92,35.52％);among 259 cases of HAI,172 strains of pathogenic bacteria were isolated,the major pathogen was Acinetobacter spp.(n =40,23.26％);incidence of HAI was high in neonates with gestational age ≤32 weeks,birth weight≤1 500 g,length of hospital stay ≥10 days,duration of antimicrobial use≥10 days,mechanical ventilation,deep venous catheterization,and feeding intolerance,difference was statistically significant (all P＜0.001).Conclusion Incidence of HAI in NICU is high,effective prevention and control measures should be formulated according to its risk factors,so as to reduce the occurrence of HAI in neonates.
