Based on the analysis of blended learning characteristics, a blended learning pro-cess model including preliminary analysis, learning activities design, blended evaluation was con-structed. Then, a blended learning case study was carried out by taking the Fourth Military Medical University Information Security course as an example. The implement methods of setting learning goal, selecting learning content, constructing learning environment, organizing learning activities and course evaluation, were described in detail. Lastly, from the effectiveness questionnaire, it could be shown that blended learning motivated the learners' enthusiasm significantly. In order to improve the learning performance, we proposed that blended learning activities must be flexible and adaptive,and integrate face-to-face learning with online learning effectively.

Objective To analyze the relationship between dynamic change of GPI-80 and disease severity and prognosis of childhood anaphylactoid purpura. Methods Patients were collected and divided into three groups according to their clinical features: purpura group (purpura only), mixed group (purpura + arthritis + gastrointestinal bleeding) and nephritis group. There were 20 patients in each group. GPI-80 expression on the neutrophils was detected by flow cytometry during acute and regressive phases of the disease. GPI-80 expression was compared among different groups and different phases. Renal biopsies were performed in 20 nephritis patients. Results GPI-80 expression was significantly increased in all patient groups compared with that in the normal control (P 0.05). No significant difference of GPI-80 expression was found among 20 nephritis patients with different pathological patterns. Forty-two patients (10 in purpura group, 15 in mixed group, and 17 in nephritis groups) were followed up and GPI-80 expression was detected at the time of discharge and 2 weeks after discharge, the results showed that GPI-80 expression was decreased from 93.26% (?7.89%) at acute phase to 91.37% (?6.9%) at regressive phase with an average interval of 13.5 days. Most of them (35/42) further decreased to 38.44% (?7.8%) in 2 weeks after discharge. GPI-80 expression remained high in 7 patients for 2 weeks after discharge and relapsed in 5 patients within 1 month after discharge. Conclusions High GPI-80 expression is related to the severity of the disease. The decrease of GPI-80 takes place later than the improvement of clinical symptoms. Children with persistently high GPI-80 expression are likely to relapse. It seems that there is no correlation between GPI-80 expression and different pathological patterns of nephritis.

Service for key subjects is important for medical information institutions nowadays.This paper discusses the necessity of providing subject-oriented service,and proposes three service modes:information transmission mode,information analysis mode and information navigation mode.In addition,the guarantee measures are also discussed,including constructing a security system for subject literature,training high-quality services team,and promoting subject information service brand.

It is proposed that following peripheral nerve injury abnormal sprouting of Aβ fiber primary afferent neurons in the spinal cord contributes to the allodynia that often occurs with such injury. The present investigation is to determine whether this sprouting is reversal after compression of peripheral nerve was relieved. In a rat model of neuropathic pain made by rat sciatic nerve compression,chorela toxin B subunit conjugated horseradish peroxidase (CB-HRP) was used to trace the termination of Afiber primary afferents and sections were reacted for using tetramethylbenzidine (TMB) as the chromagen. We demonstrated that the compression to the sciatic nerve also results in hyperalgesia and novel transganglionic CB-HRP staining in laminae Ⅱ, and this sprouting can not be reversed by decompression. This structural reorganization in central nervous system and its irreversible character may contribute to the development and maintenance of neuropathic pain.

Objective To realize the contamination status of dental unit waterlines (DUWL)in general hospitals, and provide scientific evidence for making preventive measures.Methods Three hospitals were selected for study, water source adopted by hospital A,B and C was running water,reservoir water,and filtered water through reverse osmosis filtration system respectively,specimens of dental handpiece spray water and flushing water of dental chair units were collected quarterly,total bacterial colony in water were detected.Results The qualified rate of source wa-ter,handpiece spray water,and flushing water in hospital A was 75.00%(3/4),0 (0/40)and 0 (0/40)respectively,col-ony count of handpiece spray water and flushing water was (1.20×103 -5.53×104 )CFU/mL(M=3.80×104 CFU/mL) and (2.11×104 -1.66×105 )CFU/mL(M=4.80×104 CFU/mL)respectively.The qualified rate of source water,hand-piece spray water,and flushing water in hospital B was 50.00%(2/4),60.00%(24/40)and 72.50%(29/40)respectively, colony count of handpiece spray water and flushing water was (0.00 -3.71 ×106 )CFU/mL(M=83.00 CFU/mL)and (0.00-2.39×106 )CFU/mL(M=72.00 CFU/mL)respectively.The qualified rate of source water,handpiece spray wa-ter,and flushing water in hospital C was 100.00%(4/4),55.00%(22/40)and 65.00%(26/40)respectively,colony count of handpiece spray water and flushing water was (0.00-6.20×103 )CFU/mL(M=96.00 CFU/mL)and(0.00-1.63×103 )CFU/mL(M=87.50 CFU/mL)respectively.Conclusion Water of DUWL in general hospitals is seriously con-taminated,disinfection and standardized management of source water and DUWL must be strengthened.

BACKGROUND:The establishment of a standardized clinical liver transplantation specimen bank is the primary condition for scientific research in this field, which can help to provide a qualified sample resource platform for research. OBJECTIVE:To primarily establish biological specimen bank of hepatocelular carcinoma for liver transplantation, to explore the standardized procedures of specimen colection, processing and preservation of hepatocelular carcinoma for liver transplantation, and to establish the sound and comprehensive information management system of clinical information of colected specimens. METHODS: In accordance with standardized procedures to establish biological specimen banks, the operational processes and quality control system were formulated. Liver tissue and blood samples of hepatocelular carcinoma recipients undergoing liver transplantation were regularly colected, managed and stored. Simultaneously, liver tissue and blood samples of benign liver disease in liver transplant recipients and of healthy donor were colected as controls. A systematic management was conducted in colected specimens and corresponding clinical information. RESULTS AND CONCLUSION:From August 2009, tissue and blood samples of 501 cases of receipts and donors undergoing liver transplantation with complete clinical information were colected from the specimen bank, including 203 hepatocelular carcinoma specimens, 214 benign liver disease specimens and 84 healthy donor specimens. These specimens included tumor tissue, adjacent tissues and distal non-cancerous tissue specimens, totaly 1 773. A total of 45 specimens were randomly selected for quality monitoring. The colected specimens had a high quality. Specimen information data computer management system was developed. This study initialy established a standardized research-based clinical transplantation specimen bank, which is helpful to elevate sample quality and has a good manipuility.

Objective To investigate the relationship between metabolic syndrome (MS) and education level in Su-Xi-Chang area to provide evidence for healthcare policy making. Methods A clustered sampling of 6798 subjects from Su-Xi-Chang areas of Jiangsu Province was included. Questionnaires and physical examinations were completed to collect clinical data. Logistic regression was used to analyze weather education level could be an independent risk factor of MS. Results Significant differences were found in waist circumstance (WC) ,systolic blood pressure (SBP) and fasting blood glucose (FBG) among participants with different education level. Significant differences were also existed in triglyceride and diastolic blood pressure (DBP) between subjects with higher and lower education level ( P＜0. 05 ). In single-factor or multivariate analysis, education level was negatively correlated with the prevalence of MS (P＜0. 05 ). Conclusions Education level may be an independent risk factor of MS. People with low and moderate education level have higher risk of MS. Therefore,it is recommended that health-related information should become an integral part of the compulsory education system.
