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.

Objective To discuss the effect of azithromycin on the airway inflammation in children at high risk for asthma by detecting the serum concentration change of eosinophil cationic protein(ECP), intedeukin-8(IL-8) and nitrogen oxide(NO), and also to explore the effect of azithromycin on secondary prevention of asthma. Methods Two hundred and twenty three cases of primary asthmatic attack with atopy (eczema, family asthmatic history) were collected and divided into four groups(group A, B,C,D) after asthmatic symptoms relief, group A was taken orally with azithromycin(5mg/kg Biw), group B was inhaled budesonide(0.5mg Bid), group C was taken orally with singulair (4mg qN),and group D was only given with symptomatic treatment. The vein blood was sampled on the first day in hospital, before and after medication respectively when treatment of three months was completed. Serum concentration of ECP and IL-8 was obtained by ELISA methods, and NO was measured by nitric acid enzyme reduction method. Clinic service and telephone follow-up was taken for one year. Results After three monthes intervention, there was significant difference in the serum concentration of ECP, IL-8 and NO at group A, B, C compared with group D( P<0.01 ). There was no significant difference in decrease of ECP and NO between group A and B( P > 0.05), but decrease of ECP and NO in group C was significant difference compared with group A( P<0.01). The serum concentration of IL-8 in each group was obviously decreased especially in group A, and difference was obvious between group A and group B,C( P<0.01). There was no significant difference in the cases of asthma recurrence within three months and asthmatic recurrence within one year between group A and group B, group C and group D respectively. Conchlsions (1)The medication of azithromycin might result to decrease the serum concentration of ECP and NO, especially for IL-8 in children at high risk for asthma. (2)The effects of azithromycin on change of ECP and NO in children at high risk for asthma were similar to budesonide, but different with montelukast, while the inhabitant effects of IL-8 were different with inhaled steroid hormone and leukotriene receptor obviously. (3)There was some valid contribution of azithromycin actting on the secondary prevention of asthma in our investigation.

Objective To explore the intrinsic link between neuro-endocrine-immune (NEI) network and the viscera-state.Methods Using three databases namely TCM database, Chinese pharmacy database and combination of TCM and WM database in China Academic Journals Database, the authors searched and collected NEI-related indicators published on journals for the viscera-state researches. Then a related database was established for data mining. Through analysis of association rules, analysis of the relationship among diseases, syndromes, therapeutic principles, combination of disease and syndrome, and NEI network related indicators were performed for association rules and directional network diagrams.Results Through the association analysis, the authors drew 44 directional network diagrams of high-frequency disease positions, syndromes, therapeutic principles and NEI network related indicators, and obtained 19 association rules. Kidney and liver essence research focused on HPG axis, HPA axis, and HPT axis. Spleen essence research focused on brain-gut peptide related indicators. Heart essence research focused on vascular endothelium function indicators. Pulmonary essence research focused on humeral immunity, ET and TNF-α.Conclusion It was feasible to explore the intrinsic link between NEI network and the viscera-state by using data mining. Differences among study on NEI network of five-organs systems were found, which is of great significance for researches on the essence of the viscera-state.

Objective To investigate the influence of health care workers’(HCWs)hand hygiene intervention in healthcare-associated infection(HAI)in an intensive care unit(ICU).Methods Intervention measures of hand hygiene were adopted,effective supervision and management systems were established,hand hygiene compliance and HAI rate be-fore intervention(January-December 2012)and after intervention (the first stage:January-June 2013;the second stage:Ju-ly-December 2013)were compared.Results A total of 4 066 patients were surveyed,HCWs’hand hygiene compliance rate before intervention was 50.03%,the first and second stage after intervention was 61.80% and 64.57% respectively,there was increasing trend (rs=1.00,P<0.001).HAI before intervention was 5.48%,the first and second stage after inter-vention was 3.86% and 3.30% respectively,there was decreasing trend (rs=-1.00,P<0.001).Significant decreasing trends were found in rates of catheter-related bloodstream infection(CRBSI),catheter-associated urinary tract infection (CAUTI)and ventilator-associated pneumonia(VAP)(rs=-1.00,P<0.001).There were negative correlations between hand hygiene compliance rate and the infection rate of ICU,infection rate of CRBSI,CAUTI and VAP (P<0.05 ). Conclusion The improvement of hand hygiene compliance can effectively reduce the incidence of HAI in ICU ward.
