Laboratory diagnostics is an important discipline functioning as a bridge between basic and clinical medicine and it is closely associated with the diagnosis of clinical physician.But there are some problems in the laboratory diagnostic teaching including unreasonable curriculum standard,simple teaching method and unpractical theory.This paper explored and summarized the problems and the reform of laboratory diagnostics teaching mode for students of clinical medicine.

Objective To deeply understand the postoperative real experience of colostomy patients on ostomy management, and try to explore the difficulties and needs after discharge in order to provide theoretical basis for postoperative nursing intervention. Methods By using phenomenological research method, 10 colostomy patients were interviewed face- to- face, and the content was analyzed by Colaizzi method. Results Three themes were concluded: self- care obstacle related to ostomy; self- growth brought by ostomy; expectations for social support and family care. Conclusions Colostomy patients have to face so many problems after operation on ostomy management, and hospital, society and family have responsibility to help patients adapt to ostomy as soon as possible and improve their quality of life.

Objective To study the relationship between serum tumor marker level and the apoptosis regulation gene of tumor tissue in the patients with primary hepatocarcinoma .Methods 40 cases of primary hepatocarcinoma and 40 healthy people were in‐cluded into the observation group and control group .Then the levels of tumor marker GP73 ,TK1 ,DKK1 in serum and the expres‐sion of apoptosis regulation gene in tumor tissue were detected in the two groups .Results The serum GP73 ,TK1 and DKK1 levels of the observation group were significantly higher than those of the control group ,the difference was statistically significant (P<0 .05) .The apoptosis inhibiting gene Plk1 ,Livin and Xiap levels in the hepatocellular carcinoma tissue were higher than those in the adjacent normal tissues ,while the pro‐apoptotic gene M TS1 ,Caspase‐3 and Caspase‐8 levels were lower than those in the adjacent normal tissues ,the difference had statistical significance (P< 0 .05) ;serum GP73 ,TK1 and DKK1 levels were positively correlated with Plk1 ,Livin and Xiap levels and negatively correlated with M TS1 ,Caspase‐3 and Caspase‐8 levels .Conclusion The levels of se‐rum GP73 ,TK1 and DKK1 in the patients with primary hepatocarcinoma are abnormally increased ,moreover which are closely cor‐related with the apoptosis regulating gene expression and the ideal indexes to evaluate the disease condition of primary hepatocarci ‐noma .

Objective:To prove whether La protein could effect the replications of the HBV in cultured cells.Methods:Three specific SiRNAs for human La protein was obtained by transcription in vitro. After transfection with the SiRNAs into HepG2.2.15 cell, the levels of La protein mRNA and HBV DNA were detected by real-time PCR.Results:The HBV DNA secreted by the cell transfected with the SiRNAs was reduced with reduction of the mRNA of the La protein.Conclusion:The La protein can protect the replications of the HBV in cultured cells.

Objective To investigate the expression of sialic acid-binding immunoglobulin-like lectin-one (Siglec-1, also called CD169) in lymphocytes, monocytes and neutrophils in peripheral blood in patients with coronary heart disease(CHD), and explore the relationship between Siglec-1 expression and atheresclerosis. Methods CD145 CD169 positive cell proportion and CD169 mRNA levels were respectively measured by flow cytometry and real-time quantitative reverse transcription-polymerase chain reaction (FQ-RT-PCR) in 57 CHD patients and 38 healthy controls. And the levels of serum hpids were determined by automatic biochemistry analyzer. Results The flow cytometry analysis showed that CD169 protein was not found in lymphocytes and neutrophils in both CHD patients and healthy controls. The rate of CD14 CD169 double positive ceils in monocytes in CHD group was significandy higher than that in healthy controls [(12.7±2.4)% vs (1.0±0.3)% ,t =23.2,P<0.01]. And FQ-RT-PCR analysis showed that the mean CD± mRNA copy number in PBMCs in CHD group was significantly higher(3.2 fold) than that in healthy controls [t = 6. 59, P < 0.01]. However, neither differences of CD169 protein positivities [[(12. 2 ± 2. 3) %vs (13.4±2.5)% ,t = 1.87,P >0.05] nor mRNA levels [3.64 fold vs 2.79 fold when compared with healthy controls,t =0. 98, P > 0. 05] were found between CHD patients with normal and abnormal levels of serum Lipids. Conclusions CD169 is mainly expressed in human tissue-resident macrophages but not expressed in peripheral blood monecytes. And when the monocytes is stimulated by inflammation, the expression of CD169 is increased. In patients with CHD, the increased expression of CD169 protein and mRNA level has demonstrated the activation of monocytes in peripheral blood. CD169 and CD169-mediated monocytes activation may play an important role in the development and progression of atherosclerosis.
