Objective To study the relationship between chemokines monocyte chemoattractant protein-1(MCP-1),reduced upon activation of normal T cell expressed and secreted chemokine(RANTES) and experimental allergic neuritis(EAN).Methods EAN models were induced in Wistar rats by immunization with rabbit sciatic nerves homogenate and complete Freund's adjuvant(CFA).Expressions of MCP-1,RANTES in the sciatic nerves of experimental rats were detected by immunohistochemistry technology at different time.Results The maximum MCP-1 positive cells in the sciatic nerves were detected at 9th d.The expression of MCP-1 in EAN group was obviously higher than that in control group at 9th,15th and 21th d(all(P

OBJECTIVE: To explore the development channel of on-line pharmacy in China. METHODS: The problems existing in the individual customers and the retail chain pharmaceutical enterprises were analyzed. RESULTS & CONCLUSIONS: The relation between the individual customers and the retail chain pharmaceutical enterprises should be coordinated when developing the on-line pharmacy. Only when the problmes such as the psychology and habbits of individual customers, and the running cost, drug safe distribution, network development and so on in the retail chain pharmaceutical enterprises have been solved can the on-line pharmacy smoothly developed.

Objective To observe the expression and role of HSP70 in human epidermis and cutaneous neoplasms.Methods 56 cases of epidermis tumors,including 29 biopsy samples from basal cell carcinoma, 27 from squamous cell carcinoma,and 30 from normal human skin were investigated. HSP70 expression was examined by immunohistochemical SABC staining with specific monoclonal antibodies.Results The expression of HSP70 was detectable in the cytoplasm throughout the epidermal cell layers in normal human epidermis,HSP70 expression in the tumor cells in basal and squamous cell carcinomas was reduced (P

Endophytic fungi played an important role in the growth of its host plant. To investigate the mycorrhizal characteristics and the distribution of fungi in the root, an endangered wild plant-Dysosma versipellis was collected and observed by electron microscope. The results showed that the host was closely associated with endophytic fungi. The fungi were mainly distributed in the epidermis and cortex. The aseptate and septate fungi with swollen hyphae were observed in some cell of the cortex. The result provides a reference for the study of mycorrhizal structure of Dysosma genus and the interaction between the fungi and its host.

Objective To investigate the infection and distribution of human papilloma virus (HPV) types in patients with infiltrative cervical cancer (ICC) and cervical intraepithelial neoplasia (CIN) in Chongqing. Methods Fifty-eight cases diagnosed with ICC or CIN[KG-*6]Ⅱ to Ⅲ,which were confirmed by histopathology in the Tumor Hospital of Chongqing,were included in the analysis. DNA enzyme immunoassay (DEIA) and SPF10 LiPA25 (version 1) testing was used for DNA extraction and extension,and linear probe reverse hybridization to detect lesions HPV type. Results HPV infection were detected in 56 of 58 specimen,the positive rates of CINⅡ,CINⅢ and cervical cancer were 100.00%,100.00% and 95.00% respectively. A total of 13 types were detected. HPV16 infection rate was up to 60.00%,followed by HPV18(7.69%),HPV58(7.69%),and HPV31(4.62%). Conclusion HPV16 is still the most common type in Chongqing. HPV18,HPV58 and HPV31 also has a high prevalence.
