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

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.

The doctor-patient relationship is always the focus in the society. The relationship seems more complex and sensitive in the pediatric surgical ward because its patients are kids. However, the pediatric surgical residents' ability of doctor-patient communication is lack of systemic and norma-tive training, which is not good for the mutual understanding between doctors and patients. This study explores how to enhance the residents' doctor-patient communication skills from the perspective of awareness, professional knowledge and some specific skills. In the meantime, it discusses the need to train the teachers and set up a regular examination-assessment system.

Abstract BACKGROUND: Recently, microcarrier culture as a high concentration cel culture technology has been used in hepatocyte culturein vitro. OBJECTIVE:To periodicaly observe the morphological changes of human hepatocyte L-02 cultured by the spherical porous chitosan microcarrier. METHODS:The self-made spherical porous chitosan microcarrier sample as a support to culture human hepatocytes L-02 acted as experimental group; non-spherical porous chitosan microcarrier as a support to culture human hepatocytes L-02 as control group. Cels in two groups underwent cel count at regular time, and the morphological changes were observed in the experimental group, including inverted phase contrast biological microscope observation and scanning electron microscope observation. RESULTS AND CONCLUSION:The quantity of cultured cels in the two groups was increased in the first 3 days and reached the peak at the 3rd day. The cel quantity in the experiment group was obviously higher than that in the control group (P < 0.05). There was no significant difference in the three samples of the experimental group (P > 0.05). The quantity of hepatocytes adhered to the microcarrier surface was gradualy increased in the former 3 days under the inverted phase contrast biological microscope. There were lots of cel clusters on the surface of a greater part of microcarriers, with the total survival rate of more than 90%, and hepatocytes kept a good morphological structure. Under the scanning electron microscope, lots of hepatocytes adhered tightly to each other on the surface and section of microcarrier as wel as inside the microcarrier. It is indicated that the self-made spherical porous chitosan microcarrier as a support in three-dimensional environment can undergo cel culture with high concentration.

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.

Subcutaneous insulin resistance is a condition in which glucose is insensitive to insulin from the subcutaneous tissue,but sensitive to that by intravenous injection.The mechanism of subcutaneous insulin resistance is mainly associated with skin obstruction or delayed entry of insulin into blood circulation.The treatment of the problem involves Aprotinin,anticoagulant and intramuscular injection of insulin.This paper offers an overview of the advances in the researches of subcutaneous insulin resistance.

In recent years, traditional Chinese medicine combined with 5-fluorouracil (5-FU) in the treatment of tumors, especially digestive system tumors, has achieved promising results.The current research shows that the combination of traditional Chinese medicine and 5-FU can enhance tumor inhibition rate, prolong survival period of patients, improve immunity and quality of life of patients, and significantly reduce side effects such as bone marrow suppression, liver and kidney toxicity and gastrointestinal reactions and so on.Therefore, traditional Chinese medicine combined with 5-FU can have synergistic and attenuated effects.

Objective To observe the clinical curative effect of SCH 1000 combined with Tanreqing on chronic obstructive pulmonary diseases(COPD). Methods 96 patients with COPD were randomly recruited into a control group and a treatment group. The control group was treated with SCH 1000 aerosol and the treatment group was treated with SCH 1000 aerosol combined with Tanreqing injection. Results The treatment group had better clinical curative effects than the control group, with (P<0.05) .Conclusion The treatment of SCH 1000 combined with Tanreqing on COPD is effective.

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.
