Clinical medicine and its teaching patterns put forward the new demand to the teaching of laboratory diagnostics. According to the teaching objectives and development tendency of laboratory diagnostics, a novel teaching pattern based on organ-system diseases was established through systematical reform measures. The course content system was reconstructed and focused on the diseases. And the professional teacher group carefully orchestrated, applied new teaching methods,such as case-based learning and problem-based learning. The independent learning on a resource sharing network platform was encouraged, and the evaluation system was innovated. The novel teaching pattern has obtained gratifying achievement, and showed a bright prospect of development.

The postpartum depression outcome and the effect of psychological intervention were studied in order to reduce the occurrence and development of the postpartum depression. A survey of 4000 women within 4-6 weeks postpartum in 80 communities in Shenzhen, China was performed using random cluster sampling method. By employing Edinburgh Postnatal Depression Scale (EPDS) as a screening tool, the positive women (defined as EPDS ≥10) were randomly divided into intervention group and control group at a ratio of 1:2. The women in the intervention group were treated by means of mailing postpartum depression prevention and treatment knowledge manual, face-to-face counseling, and telephone psychological counseling interventions aiming at individual risk factors, while those in the control group were treated with conventional methods. EPDS scores were assessed in these two groups again at 6th month postpartum. Totally, 3907 valid questionnaires were obtained. All the 771 positive women were divided into two groups: 257 in the intervention group, and 514 in the control group. At 6th month postpartum, the EPDS scores in the intervention group were decreased significantly, from baseline stage (12.84±3.02) to end stage (3.05±2.93), while EPDS scores in the control group were reduced from 12.44±2.78 to 6.94±4.02. There were significant differences in the EPDS scores at end stage between the two groups (t=13.059, P<0.001). Psychological intervention can reduce postpartum depression, with better maternal compliance. It is feasible and necessary to establish postpartum depression screening and psychological intervention model in community-hospital and include the postpartum depression screening, intervention, and follow-up into the conventional healthcare.

The most of secreted proteins are exported by Sec translocase (secretion pathway). SecA ATPase is one of the most important subunit in the Sec translocase, which is preprotein translocase nanomotor that undergo membrane insertion and deinsertion to drive preprotein across the bacterial inner membrane, and SecA is indispensable to bacteria. It should be presumed that the compound which inhibits the activity of SecA ATPase probably can be used as the candidate of bactericide. A secA gene from Pseudomonas aerugi- nosa PAO1 was amplified and expressed in Escherichia coli BL21.19 (secA13). It has been shown that the wild-type SecA of Pseudomonas aeruginosa could fully complement the E. coli amber (secA13) mutant at the non-permissive temperature. So a cell level screening model targeting on SecA was established based on the above result. The inhibition of PaSecA ATPase activity was applied to validate the specificity of the cell-based method. Two positive samples based on both of cell and enzyme activities will be further studied.

To explore the related risk factors and outcome in pregnancy- induced hypertension patients with Ⅲ phase of retinopathy.
●METHODS: A total of 105 pregnancy - induced hypertension patients with Ⅲ phase of retinopathy in our hospital from Januany 2012 to December 2013 were enrolled. Clinical date of them were collected to analyze.
●RESULTS: The occurrence of pregnancy - induced hypertension patients with Ⅲ phase of retinopathy were positively correlated with the course of the disease, blood pressure, proteinuria, and it was higher occurred in cold winter and spring, timely termination of pregnancy and appropriate hormone therapy can promote the recovery of vision, and improve outcomes of pregnancy.
●CONCLUSlON: The occurrence of pregnancy - induced hypertension patients with Ⅲ phase of retinopathy associated with season and disease severity. Timely treatment can restore normal vision, improve maternal and neonatal prognosis. Routine examination of fundus examination should be used as the pregnancy induced hypertension syndrome.

OBJECTIVEThe present study is concerning qualitative and quantitative detection of Poria cocos quality based on FT-near infrared (FT-NIR) spectroscopy combined with chemometrics.

METHODThe Poria cocos polysaccharides contents were determined by UV. Transmission mode was used in the collection of NIR spectral samples. The pretreatment method was first derivation and vector normalization. Then principal component analysis (PCA) was used to build classification model and partial least square (PLS) to build the calibration model.

RESULTThe results showed that conventional criteria such as the R, root mean square error of calibration (RMSEC), and the root mean square error of prediction (RMSEP) are 0.944 0, 0.072 1 and 0.076 2, respectively. The misclassified sample is 0 using the qualitative model built by PCA.

CONCLUSIONThe prediction models based on NIR have a better performance with high precision, good stability and adaptability and can be used to predict the polysaccharose content of Poria cocos rapidly, which can provide a fast approach to discriminate the different parts of Poria cocos.

Objective To investigating knowledge,attitudes,current behavior among primary school students on nutrition and food safety in two State-level poverty-stricken counties,and to explore the best educational model on nutrition and food safety.Methods 478 pupils at 4-6 grades were selected,using the method of stratified cluster sampling and questionnairs.Results The average score on knowledge was 18.66 ± 3.75,with the qualified rate as 61.09％ (the highest was 60.6％).The average score in the section of attitude was 5.82 ± 1.50.More than 97％ of the students agreed that it was necessary to receive knowledge on nutrition and food safety.The average score of behavior was 8.52 ± 2.56.Conclusion Rate of awareness on knowledge of nutrition and food safety had greatly improved among the students under study.Their habit tended to be more regular.However,we also noticed the gap between knowledge and behavior on this issue.

Objective To review our experiences in portaazygous disconnection for the treatment of portal hypertension and to analyze the causes of postoperative complications. Methods We reviewed the results of 236 patients with portal hypertension who were treated with disconnection from April 1994 to July 2002. Results Postoperative complications occurred in 65 of all the patients(the incidence rate was 27.5%). Twenty-four patients experienced postoperative infection(10.2%),12 patients suffered from intraabdominal massive bleeding(5.1%),12 from massive ascites (5.1%),8 patients suffered from recurrent upper gastrointestinal bleeding (3.4%),7 patients experienced acute thrombosis of portal venous system(3.0%). Two patients suffered from multiple organ dysfunction syndrome (1.0%). The operative mortality was 3.4%(8/236). The main causes of death included intraabdominal massive bleeding and severe infection with MODS. Conclusions The occurrence of postoperative complications was related with the selection of patients,thorough portaazygous disconnection and perioperative management.
