Objective To investigate the clinical effect of 153 Sm-EDTMP treatment on pain palliation in the patients with bone metastasis of lung cancer, breast cancer or prostate cancer. Methods 166 patients with bone metastasis of cancers were intravenously injected 18.5～37 MBq/kg (0.5～1.0 mCi/kg ) body weight of 153 Sm-EDTMP, once a month or two months. Results The effective rate of pain palliation of 153 Sm-EDTMP treating bone metastasis of lung cancer, preast cancer and prostate cancer were 68.5%, 89.3% and 100%, respectively. The efficacious rate of pain palliation in breast and prostate cancers was significantly higher than that in lung cancer (P

Objective:To investigate the protection of acupuncture on damaged myelin sheath from the poinr of view of neurological functional recovery and morphological changes of the myelin sheath.Methods:Eighty-nine adult male Sprague-Dawley rats were randomly allocated to normal (n=5),sham-operation (n=21),model (n=21),early acupuncture (n=21) and late acupancture (n=21) groups.A model of middle cerebral artery occlusion was induced by the intraluminal filament method.Acupuncture was performed at different time points after ischemia.Neurological function and morphological changes of the myelin sheath of ischemic focus were observed by using the methods of neurological deficit scores and Pal-Weigert's myelin staining.Results:Neurological deficit scores at 2.5 hours after the procedure in the model group increased significantly (P＜0.05).qhe scores decreased somewhat as the time elapsed.The internal capsule had obvious demyelination and recovered slowly.Neurological deficit scores in rats at each time point decreased faster in the acupuncture group compared with the model group,and they decreased significantly at day 3 (P＜0.05);the extent of demyelination was significantly alleviated.Neurological deficit scores decreased faster in the early acupuncture group compared with the late acupuncture group (P＜0.05);and demyelination in the early acupuncture group seemed milder at day one.Conclusions:Early acupuncture is beneficial to remyelination and neurological functional recovery after cerebral ischemia.

Surface plasmon resonance (SPR) sensing technology is a high-tech optical detection technolo-gy developed quickly in recent years, which combines biology, polymer chemistry and sensing technologies to form a rapid, sensitive, specific, portable and easy to operate detection technology. This paper outlines the mech-anism of SPR sensing technology for detection of low molecular weight analytes, the main application methods and research progress, discusses the advantages and shortages of the method, and foretastes the development prospect of this technology.

Objective To observe clinical effect of treating chronic obstructive pulmonary disease(COPD) in exacerbation stage with aerosol inhalation of budesonide combined with Chinese herbal enema. Methods 36 cases with COPD were randomly recurited into a control group and a treatment group. The control group was treated with routine western medicine, and the treatment group was treated with aerosol inhalation of budesonide combined with Chinese herbal enema. The clinical effect was observed in both groups, Results The total effective rate in the treatment group and the control group was 88.9% and 72.2%, respectively, showing significant difference between the two group. (P<0.05) .Conclusion The treatment of aerosol inhalation of budesonide combined with Chinese herbal enema on COPD is better than routine western medicine.

This paper stated the design of DPK colour LCD module and its application for the medical instrument. The hardware interface between MCS-51 and DPK LCD module is presented and the software driver base on KeilC51 language is introduced in this paper. The LCD module is well used in the "Cerebral oximeter for the newborn".

College of American Pathologists (CAP) and International Standard Organization (ISO)15189 accreditation provides requirements to the verification and validation tests for clinical molecular diagnostic assays.The article will introduce the requirements in these aspects including the differences between the two accreditation systems,the differences between the verification and validation tests,the essential factors and standardized framework of the verification and validation tests for clinical molecular diagnostic assays.

Exosome is a sort of vesicle structure attached to cell membrane and released by cells, which contains numerous bioactive molecules, such as proteins, lipids, mRNA, microRNA and DNA fragments. These bioactive molecules are involved in the regulation of many biological processes, not only the participation in the occurrence and development of diverse diseases, but also the close relationship with the invasion and metastasis of tumors. The recent study has indicated that lots of exosomes released from cancer cells participate in a variety of pathological processes as a messenger of cell functions. This article will elaborate the function and application of exosomes in some malignant cancers.

Medical students′ professional spirit cultivation is an important content as well as a basic require-ment of the Preeminent Doctor Education and Training Plan. Currently, there are several problems in medical tal-ents′professional spirit cultivation, such as the unstandardized curriculum, the lack of subjective experience, and the ignorance of the unity of education stages, student differences and coherence. This study intends to explore thedouble teacher method, in which both clinical teaching doctors and medical ethics teachers engage in the medi-cal students′professional spirit cultivation. Its purpose is to build a bridge between medical ethics education in uni-versities and the clinical practice, and further to integrate them through doctors′ and teachers′ joint participation, which will significantly enhance medical students′practice ability of medical moral.
