OBJECTIVE To understand the current status of prevention and control of traditional Chinese medicine(TCM)diagnosis and treatment technique-related infections in various grades of hospitals in Jiangsu Province so as to provide bases for management departments to put forward the norms.METHODS The questionnaire was de-signed by the methods such as Delphic correspondence,the current status of prevalence,prevention and control of TCM diagnosis and treatment technique-related infections among the health care workers in the hospitals of Jiang-su Province was investigated by using convenience sampling method.RESULTS A total of 508 questionnaires were collected from 13 cities of Jiangsu Province.The results showed that the TCM treatment room(63.64％)was the most common operation site for minimally invasive TCM diagnosis and treatment techniques,the bedside(62.50％)of the patients was the major operation site for Chinese medicine enema,and the central sterile supply department(55.31％)was the preferred choice of cleaning and disinfection site for daily recycled TCM apparatu-ses.'One person used for once,airing and preparing for later use after cleaning and disinfection for once'was the major approach taken for the cleaning and disinfection of Gua Sha boards(82.45％)and TCM pots(87.50％).67.87％of the health care workers said that they wound cleaned and disinfected the medical apparatuses of dress-ing,ironing and fumigation every time after the use.The natural ventilation and ultraviolet light(50.39％)was the major method that was taken for the ventilation and disinfection of the treatment rooms for TCM operations.Quick-drying hand disinfectant and non-touch hand-washing equipment(39.37％)were the most commonly e-quipped hand hygiene facilities.CONCLUSIONS The prevention and control of TCM diagnosis and treatment tech-nique-related infections and the health care workers' capabilities for prevention and control of the infection have made remarkable progress in the various grades of hospitals in Jiangsu Province.However,there is still room for further improvement,and the standardized management and construction should be completed so as to safeguard the TCM diagnosis and treatment techniques.

OBJECTIVETo determine the composition, structure, trace elements and thermal stability of Tibetan medicine Nanhanshuishi.

METHODThe trace elements, the structure, and the thermal stability of Nanhanshuishi were assayed and calculated by X-ray fluorescence spectrometry (XRF), inductively coupled plasma optical emission spectrometer (ICP-OES), atomic fluorescence spectrometry (AFS), inductively coupled plasma mass spectrometry (ICP-MS), X-ray power diffraction (XRD), TG-DTA.

RESULTThe results indicated that the phase is mainly made up of CaCO3 (Rhombohedral, R-3c) in Nanhanshuishi. The analysis of elements show that Nanhanshuishi is rich in Ca and O, and contains other more than 20 minor elements, such as Si, Mg, Fe, Al, Na, K, Zn, Mn, Pb, As, Hg etc. The result of TG-DTA show that the weight of Nanhanshuishi starts to decline from near 700 degrees C and get steady above 850 degrees C.

CONCLUSIONThe study provided scientific data for the establishment of quality standards of Tibetan medicine Nanhanshuishi.

Our previous studies demonstrated that CD151 gene promoted neovascularization in ischemic heart model. To improve the delivery efficacy and target specificity of CD151 gene to ischemic heart, we generated an adeno-associated virus (AAV) vector in which CD151 expression was controlled by the myosin light chain (MLC-2v) promoter to achieve the cardiac-specific expression of CD151 gene in ischemic myocardium and to limit unwanted CD151 expression in extracardiac organs. The function of this vector was examined in rat ischemic myocardium model. The protein expression of CD151 in the ischemic myocardium areas, liver and kidney was confirmed by using Western blot, while the microvessels within ischemic myocardium areas were detected by using immunohistochemistry. The results showed that MLC-2v significantly enhanced the expression of CD151 in ischemic myocardium, but attenuated its expression in other organs. The forced CD151 expression could increase the number of microvessels in the ischemic myocardium. This study demonstrates the AAV-mediated and MLC-2v regulated CD151 gene is highly expressed in the ischemic myocardium and cardiac-specific delivery that is more efficiently targets CD151 to the ischemia myocardium after myocardial infarction.
