RESUMO
Peripheral neuritis is one of the main common diabetes complications. Long-term development of the disease can cause gradual decreasing of nerve function or even muscle atrophy and movement difficulty. The Mongolian medicineErdun-wurile is a commonly used as a tendon-relaxing and collateral-activating medication in the clinical practice. It had good therapeutic effects in the treatment of nervous system diseases. In recent years, it has also been used in the treatment of diabetes complications. This paper provided an overview on clinical reports about Mongolian medicineErdun-wurile in the treatment of diabetic peripheral neuritis.
RESUMO
AIM: To investigate the effect of exercise stress on chronic cigarette smoking-induced downregulation of expression of large-conductance calcium-activated potassium channel (BK_(Ca)) and voltage-dependent delayed rectifier potassium channel (Kv1.5) in rat bronchial smooth muscle cells. METHODS: Rats were divided into 3 groups: normal control, smoking control and smoking plus exercise training group. The alteration of airway responsiveness and plasma cortisol level were detected, and potassium channel expression and pathological changes in lung tissue were determined with HE staining, immunohistochemistry, in situ hybridization and Western blot techniques. RESULTS: (1) Cigarette smoking induced an increase in airway responsiveness, smoking plus exercise lead to a decrease in airway responsiveness in contrast to smoking control group; (2) Plasma level of cortisol determined immediately after exercise was higher than that determined before exercise; (3) HE staining showed that there was severe chronic pulmonary inflammatory response in smoking control group, which was slight in the smoking plus exercise group; (4) The protein and mRNA expression of BK_(Ca) in cigarette smoking group were less than that in control group in BSMC, the mRNA expression of BK_(Ca) in exercise group were higher than that in smoking group; (5) The protein and mRNA expression of Kv1.5 in smoking group were less than that in control group in BSMC, and expression of Kv1.5 in exercise group was higher than that in smoking group in bronchioli. CONCLUSION: Proper exercise training can increase the expression of potassium channel BK_(Ca) and Kv1.5, and increase the cortisol secretion, which may contribute to the decreasing of airway hyperresponsiveness induced by cigarette smoking.

RESUMO
Objective To study the effect of TBTCl on the immunity of mice. Methods The mice were randomly divided into 5 groups, namely groups of negative control, low dose (0.8 mg/kg), moderate dose (4 mg/kg), high dose (20 mg/kg) and positive control. Gavage was employed to administrate TBTCl to mice for two consecutive weeks, the number of T-lymphocyte in blood and invert ability of T-lymphocytes in spleen, hemolysin in serum, clearance exponent and viscera quotiety were determined to study the effect of TBTCl on immunity of rats. Results Compared with the control, no significantly increased T-lymphocytes were seen in low dose group, in moderate dose group the number of T-lmphocyte and the production of hemolysin increased, no obvious changes in the clearance exponent and viscera quotiety were seen. In high dose group, a significantly decreased T-lymphocytes, the clearance exponent and viscera quotiety were observed. Conclusion Low level TBTCl exposure may stimulate the immune system of mice, high exposed to TBTCl may intensively inhibit the immune system.
