ObjectiveTo investigate the clinical effect of EaLeSu on cervical intraepithelial neoplasia(CIN Ⅱ~Ⅲ)patients with HPV infection treated with loop electrosurgical excision procedure(LEEP). Methods 165 cases of CIN Ⅱ~Ⅲpatients with HPV infection who underwent LEEP operation were randomly divided into observation group(n=83)and control group(n=82). In the observation group,patients were given a piece of EaLeSu in cervical wound at once in postoperative and two vaginal EaLeSu per day from the first postoperative day for eight consecutive days. The patients in the control group were treated with routine debridement and wound dressing with iodine. We observed the vaginal drainage times within 4 weeks after operative,bleeding rate,cervical wound repair,and cervical HPV DNA infection after 6 months. Results There were significant differences in the bleeding rate,vaginal drainage time,cervical wound repair and HPV DNA infection between the two groups(P < 0.05). Conclusion EaLeSu showed a definite effect on cervical intraepithelial neoplasia(CIN Ⅱ~Ⅲ)patients with HPV infection treated with LEEP.

Objective To study the relationship between histological activity index and serum of tumor nec-rosis factor-α( TNF-α) ,peripheral blood T cell subsets in patients with chronic hepatitis B.Methods Histopatholog-ical examinations were performed in 237 patients with chronic hepatitis B and 12 controls.The histological activity index( HAI) were analyzed by knodels method.These patients were divided into the four groups according to histologi-cal activity index classification:the control group(n=12),mild group(n=67),moderate group(n=89),and severe group(n=81).The serum levels of TNF-αwere determined by ELISA,and peripheral blood T cell subsets were ana-lyzed by flow cytometry.Results The serum level of TNF-αin the mild group[(29.65 ±10.15)μg/L],moderate group[(38.96 ±7.32)μg/L]and severe group[(47.73 ±6.99)μg/L]were higher than those in the control group [(13.78 ±6.40)μg/L](q=14.38,19.97,24.83,all P<0.05),significant positive correlation lied between the histological activity index classification and the serum level of TNF-α(r=0.708,P<0.05).The rate of CD8+cells in the moderate group[(27.66 ±6.63)μg/L]and the severe group[(28.98 ±5.92)μg/L]were higher than those in the control group[(22.32 ±1.84)μg/L](q=3.84,4.76,all P<0.05),and the ratio of CD4+/CD8+in the moderate group(1.32 ±0.37) and the severe group(1.19 ±0.30) were lower than those in the control group(1.67 ±0.14) (q=4.20,5.72,all P<0.05),but the rate of CD8+cells and the ratio of CD4+/CD8+showed no significance among the mild group,moderate group and severe group.Conclusion TNF-αand disorder of cellular immunity may play an important role in the development and progression of intrahepatic vascular lesion.

OBJECTIVETo screen the lentiviral vector carrying siRNA and capable of significantly suppressing the ROCK2 gene expression in the corpus cavernosum smooth muscle cells of spontaneously hypertensive rats (SHR).

METHODSWe designed and synthesized 4 siRNA fragments targeting the ROCK2 gene and packaged them into lentiviral vectors. We collected corpus cavernosum smooth muscle cell samples from 5 male SHRs and randomly divided them into groups A (non-transfection control), B (GFP lentiviral transfection), C, D, E, and F (lentiviral transfection with siRNA fragments 1 -4 targeting the ROCK2 gene). Each group consisted of 5 samples and each sample 3 x 10(4) cells. At 48 hours after transfecting MOI = 80 into the SHR corpus cavernosum smooth muscle cells, we detected the expression of GFP under the fluorescent microscope and the mRNA expression of the ROCK2 gene by RT-PCR.

RESULTSThe transfection efficiency of the SHR corpus cavernosum smooth muscle cells was > 50%. Compared with group A, the expression of ROCK2 mRNA in the corpus cavernosum smooth muscle cells showed no remarkable change in group B (P > 0.05) but was inhibited very significantly in C ([43.91 +/- 8.19]%), D ([47.15 +/- 6.64]%), and F ([25.7 +/- 6.03]%) (P < 0.01), and significantly in E ([16.81 +/- 5.94]%, P < 0.05).

CONCLUSIONWe successfully constructed 4 lentiviral vectors carrying siRNA targeting the ROCK2 gene, all of which can significantly suppress the ROCK2 expression in the SHR corpus cavernosum smooth muscle cells, and one has a highly strong inhibitory effect.

Objective:To study the wound healing effects of the extracts of Shengji Huayu Fang with different solvents and demon-strate their important role in wound healing for deep second degree burn wound. Methods:Sixty Sprague-Dawley rats were randomly di-vidied into six groups(ten rats in each group): the control group (saline), the positive control group (asiaticoside group), Shengji Huayu Fang group respectively with petroleum ether, chloroform, ethyl acetate and n-butanol as the extraction solvent. The extracts of Shengji Huayu Fang with different solvents were applied in the rats with deep second degree burn wound, and the wound healing was e-valuated by the healing rate judged by naked eyes and computer image analysis, DNA cell cycle analysis using a flow cytometry, patho-logical reports and the degree of re-epithelialization studied by the other methods. Results:The mean healing time of the chloroform ex-tracts group [(15. 67 ± 1. 12)d] was much shorter than that of the control group [(22. 87 ± 1. 01)d, P<0. 01]. The hydroxyproline content and the percentage of S-phase cells in wound tissue in the chloroform extracts group was obviously higher than those in the con-trol group (P<0. 01). Conclusion:The present study indicates that topical application of chloroform extracts of Shengji Huayu Fang is beneficial to burn wound healing, and the chloroform extracts of Shengji Huayu Fang is the main bioactive fraction.
