AIM To investigate the transdermal delivery effects of cyclosporine A solubilized in mixed micelles composed of phospholipid and different surfactants. METHODS When applied onto the excised abdominal skin of the mice occlusively, the enhancing effects of various mixed micelles on the penetration of cyclosporin A were assessed by an in vitro permeation technique. In vivo study was carried out by topical application of sodium cholate-phospholipid mixed micelles onto the mice skin and drug blood concentration was detected. RESULTS In vitro, mixed micelles containing different surfactants displayed distinct permeability and corresponded to the following order: sodium cholate > sodium deoxycholate > Trition X-100 > Tween-20. In vivo, peak drug concentration was detected at 5 h and after that the concentration fell down slowly. CONCLUSION Mixed micelles were shown to be efficient carrier for the transdermal delivery of the lipophilic polypeptide when kept in solution during the application process.

OBJECTIVETo observe the effect of Chinese medicine and pharmacy (CMP) on the mortality of senile HIV/AIDS patients as adjunctive therapy.
METHODSHIV/AIDS patients of a certain rural area of Hanna Province, who were recruited in national CMP HIV treatment trial program (NTCMTP) in 2004, were enrolled as the CMP treatment group. HIV/AIDS patients in the same village without recruiting in NTCMTP were enrolled as the non-CMP treatment group. Data related to subjects were collected from the database of NTCMTP and National HAART Reporting System. Multiple regression analysis under Cox proportional hazard model was applied to examine the risk factors for death of senile HIV/AIDS patients.
RESULTSA total of 436 HIV/AIDS were enrolled in this study, 204 in the CMP treatment group and 232 in the non-CMP treatment group. There were 70 AIDS-relative deaths in the CMP treatment group, with 8-year mortality rate of 37.74%. There were 111 AIDS-relative deaths in the non-CMP treatment group, with 8-year mortality rate of 48.34%. The 8-year mortality rate was higher in the non-CMP treatment group than in the CMP treatment group (chi2 = 5.136, P < 0.05). Results of univariate Cox proportional hazards regression analysis showed the hazard ratio in the non-CMP treatment group was 1.41 times that of the CMP treatment group (P < 0.05). Result of multivariate Cox proportional hazards regression analysis showed the hazard ratio in the non-CMP treatment group was 1.44 times that of the CMP treatment group (P < 0.05). Besides, gender and marital conditions were significantly associated with death of HIV/AIDS patients.
CONCLUSIONCMP treatment was favorable to lower the mortality rate of senile HIV/AIDS patients, and its objective evaluation awaits for further prospective study.

Abstract:Alcoholic liver disease (ALD) is one of the most common liver diseases in the world. Long-term alcoholism causes a series of pathological changes in the liver, which eventually leads to the occurrence of liver diseases with an increasing incidence. At present, significant progress has been made in the pathogenesis and pathological development of alcoholic liver disease, but the relevant mechanism of ALD has not been thoroughly studied. It is necessary to improve the existing animal model or establish a new, more comprehensive animal ALD model to simulate human ALD. Experimental animal models of ALD, especially rodents, are often used to simulate human ALD, and the ideal rodent ALD model can effectively simulate all aspects of alcohol in human liver. But so far, the commonly used animal models all have certain defects, and there is no complete animal model that can simulate human ALD. This paper reviewed the pathogenesis of ALD, related methods and influencing factors of ALD model, and provided a theoretical basis for relevant researchers to establish the ALD rodent model.
