Objective To investigate the elationship between the expression of Cathepsin D and Laminin receptors with the invasion and metastasis of gastric cancers.Methods Cathepsin D and Laminin receptors immunoreactivities were evaluated in 96 patients with gastric cancer using streptavaclin pemxidase method.Results Over expression of Cathepsin D in gastric cancer tissue was significantly related with the depth of invasion,lymphnode metastasis and grade of differentiation (P<0.01,P<0.01 and P<0.05, respectively).Moreover,the high expression of Lamninin receptors in gastric cancer had significant correlations with the invasion depth and grade of differentiation(P<0.05 and P<0.01);The positive expression of Laminin receptors were not significantly related with lymph node metastasis(P>0.05).By statistics analysis Cathepsin D had a significant positive correlation with Laminin receptors (P<0.05). Conclusion Cathepsin D and Laminin Receptors play all important role in the invasion and metastasis of gastric Cancers.

OBJECTIVE To study drug resistance status of infected bacteria in abdominal surgical wound for their countermeasures. METHODS The abdominal surgical infection of a hospital was investigated from Jan 2000 to Dec 2004.Bacterial isolation and identification were carried out complying with National Operation Procedure of The Clinical Laboratory.Drug sensitivity test was performed with KB method. RESULTS The infection rate was 4.1%.The species were predominated by Gram-negative bacilli(71.1%),especially Escherichia coli(17.2%),Pseudomonas aeruginosa(16.7%) and Klebsiella pneumoniae(12.7%),and they all beared high antibiotics resistance. CONCLUSIONS Special attention should be paid to abdominal surgical wound infection.

DNA vaccine is used in infectious diseases initially, and later is applied in neoplastic diseases, allergic diseases and other fields with the further understanding of DNA vaccine and the development of genetic engineering. DNA vaccine transfers the genes encoding exogenous antigens to plasmid vector and then is introduced into organism. It controls the antigen proteins synthesis, thus induces specific humoral and cellular immune responses. So it has a broad application prospect in allergic diseases. Compared with the traditional protein vaccines used in specific immunotherapy, DNA vaccine has many advantages, including high purity and specificity, and improvement of patients' compliance etc. However, there are still two unsolved problems. First, the transfection rate of unmodified naked DNA plasmid is not high, Second, it's difficult to induce ideal immune response. In this study, we will review the progress of DNA vaccine applications in respiratory allergic diseases and its various optimization strategies.

Objective To establish a proper extraction method for Yangxue Ruanjian Prescription (YRP) by comparing the chemical component contents and analgesic and anti - inflammatory effect of extracts extracted from YRP by different methods. Methods Water - decocting, alcohol - refluxing and alcohol - percolating methods were adopted and component indexes of paeoniflorin and gentiopicrin were determined by HPLC. The anti - inflammatory effect of the extracts were observed on mice with xylol - induced auricular swelling and analgesic effect by hot - plate method. Results The content of gentiopicrin is similar in the extracts extracted by three methods and the content of paeoniflorin is higher in alcohol - percolating extract than in alcohol - refluxing extract, lowest in water - extraction. The analgesic effect of water - decocting extract is better than that of alcohol - refluxing extract, and that of alcohol - percolating extract is weakest; the anti - inflammatory effect of the three extracts is almost the same. Conclusion Water - decocting extraction is suitable to YRP, and this is determined by the characteristics of Chinese compound prescription.

Aim To establish a hepatic carcinoma cell line with stable voltage-gated chloride channel 3 ( ClC-3 ) gene silencing through the lentivirus-mediated short-hairpin RNA ( shRNA ) method and investigate the effects of gene silencing on invasion and migration. Methods Three lentiviral vectors coding shRNA tar-geting ClC-3 gene were constructed, the recombinant plasmids were packaged into mature lentivirus by 293FT cells, and then the lentiviruses were harvested, concentrated and titrated. MHCC97H cells were infec-ted with the recombinant lentiviruses and then were se-lected to obtain cell lines stably expressing ClC-3 shR-NA. The efficiency of ClC-3 mRNA and protein ex-pression interference were determined by real-time flu-orescence quantitative PCR and Western blot, respec-tively. The effects of ClC-3 gene interference on inva-sion and migration of MHCC97 H cells were performed by Transwell chamber assays with or without Matrigel and cell scratch assay. Results The recombinant lentiviral vectors were successfully constructed and four lentiviruses were acquired after packaged by 293 FT cells. One negative control cell line and three cell lines with ClC-3 gene interference ( MHCC97 H/shClC-3-1 , shClC-3-2 and shClC-3-3 ) were successfully construc-ted after MHCC97 H cells were infected with lentivirus-es. The expression level of ClC-3 mRNA and protein in three ClC-3-silenced cells were obviously lower than the negative control cells ( P <0. 01 ) , MHCC97 H/shClC-3-2 cells showed the greatest inhibition of ClC-3 mRNA and protein expressions. As compared with the negative control cells, the ClC-3 gene interference sig-nificantly decreased invasion and migration of MH-CC97 H cells in vitro ( P <0. 01 ) . Conclusion The hepatic carcinoma cell lines with stable ClC-3 gene si-lencing were successfully established and the ClC-3 gene interference could significantly inhibit invasion and migration of MHCC97H cells.
