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.

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.

Among tumor suppressor genes, p15(INK4b) gene is gaining more attention for its important role in the progression of myelodyplastic syndrome (MDS). Serial studies demonstrated that highly frequent hypermethylation of p15(INK4b) gene, which is located at the 5'CpG island in the promoter region of exon 1 and is the main reason of inactivation of p15(INK4b) gene, occurs during the development of MDS towards AML. The assay of methylation-specific PCR (MSP) is sensitive to this pattern of methylation which is restricted to the MDS clone. Apoptosis mediated by cytokines such as Fas antigen and TGF-beta, and bHLH proteins is inhibited by the inactivation of p15(INK4b) gene. This may result in the evolution of MDS clone to AML. In as much as the close relationship between p15(INK4b) gene methylation and MDS, modulation of the methylation status of p15(INK4b) gene may be considered as a noval treatment modality for MDS.
