OBJECTIVE:To investigate clinical efficacy and safety of Xuebijing injection in the treatment of chronic ob-structive pulmonary disease (COPD) complicated with community-acquired pneumonia (CAP). METHODS:A total of 88 COPD patients with CAP selected from our hospital during Feb. 2013-Jan. 2015 were divided into control group and observa-tion group according to random number table,with 44 cases in each group. Control group received routine treatment as an-ti-infection,reducing phlegm,fluid replacement,nutritional support,etc. Based on control group,observation group was ad-ditionally given Xuebijing injection 50 mL added into 0.9% Sodium chloride injection 100 mL,ivgtt,for 30-40 min,bid, for consecutive 10 d. Clinical efficacy,application time of antibiotics,pulmonary function indexes [FEV1,FVC,FEV1/FVC,VC] were observed in 2 groups. The occurrence of ADR was recorded. RESULTS:Total response rate of observation group was 88.64%,which was significantly higher than 70.45% of control group,with statistical significance(P<0.05). The application time of antibiotics in observation group was significantly shorter than control group,with statistical significance (P<0.05). There was no statistical significance in FEV1,FVC,FEV1/FVC,VC between 2 groups before treatment (P>0.05). After treatment,FEV1 and VC of 2 groups were improved significantly,and the observation group was better than the control group,with statistical significance(P<0.05). There was no statistical significance in FVC,FEV1/EVC before and af-ter treatment and betwean the two groups (P>0.05). No obvious ADR was found in 2 groups. CONCLUSIONS:Xuebijing injection has significant therapeutic efficacy for COPD complicated with CAP and can significantly shorten the use time of an-tibiotics,improve pulmonary function with good safety.

Objective To study the effect of application of comprehensive intervention model in the three-grade prevention for metabolic syndrome(MS). Methods 180 cases of patients diagnosed as MS were chosen in our hospital from January to June 2005,and divided randomly into the experimental group and the control group with 90 cases in each group. The control group received routine general health education intervention, but not related strengthened management and intervention, the experimental group adopted an integrated management approach, to establish a model of co- management included health care workers, patients and their families. Two groups were observed in patients' knowledge, self-management level, medical compliance and various indicators, then analyzed the incidence of cardio - cerebral vascular events after intervention. Results Knowledge, self-management level, medical compliance and related indicators of patients, and the incidence of cardio-cerebral vascular events after intervention were significant between the two groups. Conclusions Comprehensive intervention model can improve the patients' health knowledge attitudes, self-management level and the metabolic function. It can reduce the cardio-cerebral vascular accidents, improve the quality of life, and has a high economic and social value, so is worth promoting.

Objective Stress radiography provides an objective tool to measure posterior knee instability.This study was conducted to evaluate the intraobserver and interobserver reliability of measurements using Telos device to quantify posterior knee instability,compared wim KT-1000 and PDT test for consistency analysis.Methods From October 2008 to June 2009,68 stress radiographs in 34 patients with posterior knee instability were taken using Telos device.The amount of posterior displacement on the radiographs was measured independently by 2 surgeons on 2 separate occasions.Changes in intraclass correlation coefficients(ICCs)were examined to assess the intraobserver and interobserver reliability of the measurement,and were compared with those from KT-1000 and PDT test for consistency analysis.Results Intraobserver ICC was 0.992,while interobserver ICC Was 0.991.There was no significant difierence between Telos and KT-1000 in pair-t test.The data from Telos device was consistent with KT-1000.The coincident ratio Of PDT test was 20% while the posterior displacement of the tibia calculated on stress radiography was 5-10 mm.The coincident ratio of the PDT was 71.4% while the posterior displacement of the tibia calculatcd from stress radiography was 10-15 mm.Conclusion Using Telos device for stress radiograph provides a reproducible method to quantify posterior knee instability,and the consistency between Telos divece and KT-1000 was reliable.The coincident ratio of the PDT test with stress radiography increased when the posterior displacement of the tibia from stress view became more severe.

Objective To investigate the activation and role of signal transduction pathway of epidermal growth factor (EGF)-epidermal growth factor receptor (EGFR)-mitogen activated protein kinase (MAPK) in proliferation of human retinal pigment epithelial (RPE) cells. Methods Human RPE cells were stimulated with 0.1%,10% foetal calfserum (FCS) and EGF(0.1, 1, 10, 50 and 100 ng/ml)in 0.1% FCS Dulbeco′s modified Eagle′s medium (DMEM) and in 10% FCS DMEM for 3 days, respectively. Immunohistochemical staining and in situ hybridization were used to observe the expressions of EGFR protein and EGFR mRNA,respectively. Activation of MAPK was detected by immunohistochemical method with specific anti-phosphorylated ERK 1/2 antibody. Results The optimal concentrations of EGF were 10 ng/ml in 0.1% FCS DMEM and 1 ng/ml in 10% FCS DMEM. After 3 days of stimulation with EGF, phosphorylated ERK 1/2 staining was detectable in nucleus of RPE cells, whereas cells presented immunostaining for phosphorylated ERK 1/2 in the cytoplasm before stimulation. Conclusions EGF may improve the expression of EGFR protein and EGFR mRNA of RPE cells, and induced MAPK nuclear translocation in a concentration-dependent manner. EGF-EGFR-MAPK signal transduction pathway may play a key role in RPE cells proliferation, and serum exerts an important acceclerating function in the process.

Conclusion: It needs to further enhance financial structure adjustment and disease control investment, increase disease control input, change government appropriation method for disease prevention and control institutions, change the government ’ s funding mode to “purchase system” , reasonably pricing public product, the government on behalf of the people buying services according to quality and quantity from the disease prevention and control institutions.

Objective To investigate the effects of filter reuse on solute clearances, safety and oxidative stress parameters in on-line hemodiafiltration(HDF) . Methods 8 stable maintained uremic patients were treated by post-dilution on-line HDF with first-use or reuse F60 polysulfone filter, respectively. Both blood-side and dialysate-side solute clearances at 20 minute of HDF or during the whole session were measured. Whole blood interleukin-1?(IL-1?) production was monitored before HDF, after HDF, and at 20 minutes of HDF at both venous and arterial lines. Plasma before and after treatment and dialysate were collected for measuring total ascorbic acid, dehydroascorbic acid and total vitamin E. Restults No difference of small molecular substance clearances was observed in blood and dialysate side, while filter reuse group had a significantly higher dialysate side clearance and a significantly lower absorption clearance for ?2-microglobulin. In contrast with stable vitamin E concentration during dialysis, total ascorbic acid level decreased after treatment, with reuse group further inducing a reduced ration of dehydroascorbic acid to total ascorbic acid. No significant changes were found in whole blood IL-1? production within and between each group, so did intra-dialysis symptoms and temperature curves. Reuse filter also caused more albumin loss through high-flux membrane than that of first-use filter. Conclusions Although reuse filter can maintain both small and large molecular weight substance clearance, it increases albumin loss through high-flux membrane. Reuse filter does not stimulate white blood cell to produce more cytokine than the first-use filter, but it increases oxidative stress, and may harm uremic patients in a long run.

Contemporary management ideas and social movements have impelled governments and service providers to value healthcare consumers' opinions and experiences. Patient satisfaction surveys have been used as a routine tool to measure a hospital's service quality from the patient's angle and patients' fidelity towards service providers. Quality improvement measures and service development strategies are consequently formulated. However, there still exist many problems in the research on and use of satisfaction surveys as a measurement tool, including lack of strategies for scientific tool selection and development, lack of standardization and analysis benchmarking, emphasis on nursing service at the expense of a hospital's overall service quality, lack of psychological surveying and research on applicability and practicability, artificially introduced bias factors in conducting the surveys, oversimplified presentation of survey results, and limited use of information, It is suggested that guidelines for tool selection and development be formulated, regional or nationwide benchmarking be established, plan designs in conducting the surveys be perfected, presentation of survey results be improved, and rational use of information be promoted.
