Objective: To investigate the awareness of hepatitis C prevention and control knowledge and its influencing factors among female sex workers (FSWs) in Jiaxing City, Zhejiang Province. Methods: According to the HIV/AIDS Sentinel Surveillance Plan, FSWs at ages of 15 to 65 years monitored by the national AIDS surveillance sentinel in Jiaxing City were recruited, and demographic information, awareness of hepatitis C prevention and control knowledge and related behaviors were collected by questionnaire surveys. Factors affecting the awareness of hepatitis C prevention and control knowledge were identified by a multivariable logistic regression model. Results: A total of 430 questionnaires were allocated, and 412 were valid, with an effective rate of 95.81%. The respondents had a mean age of (28.58±4.93) years, and included 258 unmarried FSWs (62.62%), 344 with registered residence outside Zhejiang Province (83.50%), 212 with junior high school education or below (51.46%) and 243 from high-end entertainment places (58.98%). The overall awareness of hepatitis C prevention and control knowledge among FSWs was 20.39%, and the awareness of "Transfusion of blood containing hepatitis C virus may acquire hepatitis C" (38.83%) and the awareness of "tattooing, eyebrow tattooing and ear piercing in streets or small shops may infect hepatitis C" (38.11%) were relatively low. Multivariable logistic regression analysis identified marital status (divorced or widowed, OR=0.161, 95%CI: 0.054-0.482), educational level (high school or technical secondary school, OR=2.568, 95%CI: 1.446-4.560; junior college or above, OR=6.110, 95%CI: 2.658 -14.045) and grade of entertainment places (high-end entertainment places, OR=2.756, 95%CI: 1.525-4.982) as factors affecting the awareness of hepatitis C prevention and control knowledge among FSWs. Conclusion FSWs in Jiaxing City have a low awareness of hepatitis C prevention and control knowledge, especially lacking of knowledge about the transmission routes and prognosis of hepatitis C.

On account of the dense cuticles of the fresh stem and the light, hard and pliable texture of the dried stem, Dendrobii Caulis is difficult to dry or pulverize. So, it is very important to the ancient doctors that Dendrobii Caulis should be properly treated and applied to keep or evoke its medicinal effects. The current textual research results about the preliminary processing, processing and usage methods of Dendrobii Caulis showed that: (1) In history the clinical use of fresh or processed Dendrobii Caulis as teas and tinctures were very common. (2) Its roots and rhizomes would be removed before using. (3) Some ancillary approaches were applied to shorten drying times, such as rinsing with boiling mulberry-ash soup, washing or soaking with liquor, mixing with rice pulp and then basking, etc. (4) According to the ancients knowledge, the sufficient pulverization, by means of slicing, rasping, hitting or pestling techniques, was necessary for Dendrobii Caulis to take its effects. (5) The heat processing methods for Dendrobii Caulis included stir-baking, stir-frying, steaming, decocting and stewing techniques, usually with liquor as an auxiliary material. Among above mentioned, steaming by pretreating with liquor was most commonly used, and this scheme was colorfully drawn in Bu Yi Lei Gong Pao Zhi Bian Lan (Ming Dynasty, 1591 CE) ; moreover, decocting in advance or long-time simmering so as to prepare paste products were recommended in the Qing Dynasty. (6) Some different processing programs involving stir-baking with grit, air-tightly baking with ondol (Kangs), fumigating with sulfur, which appeared in modern times and brought attractive outward appearance of the drug, went against ancients original intentions of ensuring drug efficacy.

OBJECTIVETo observe the effect of the inducible nitric oxide synthase (iNOS) gene on androgen-independent prostate cancer DU145 cells in vitro.

METHODSThe iNOS gene was transfected into androgen-independent prostate cancer DU145 cells. The positive cells were selected as the transfected group for amplification, and an empty vector (EV) group and a control group were also set. The mRNA transcription of iNOS was analyzed by RT-PCR. The morphological changes of the cells were observed, the effect of iNOS transfection on the cell growth determined using the MTB method, and the apoptosis of DU145 cells detected by flow cytometry, followed by analysis of the effect of NOS inhibitors on the transfected cells.

RESULTSDU145 cells transfected with iNOS secreted significantly more nitric oxide ([272.50 +/- 15.82] micromol/L) than those of the EV and control groups ([122.00 +/- 18.93] micromol/L and [121.00 +/- 6.98] micromol/L) (P < 0.05). The rate of cell apoptosis was markedly enhanced in the transfected group as compared with the EV and control groups ([42.78 +/- 2.01]% vs [30.65 +/- 1.46]% and [28.96 +/- 1.50]%, P < 0.05). MTP test indicated a slower growth of the DU145 cells in the former than in the latter two (P < 0.05). NOS inhibitors enhanced their growth, but with no significance (P > 0.05).

CONCLUSIONDU145 cells transfected with iNOS could secrete high-concentration nitric oxide, induce cell apoptosis, and suppress cell proliferation, which may provide a potentially effective gene therapy for advanced androgen-independent prostate cancer.
