BACKGROUND: Being a kind of anti-oxidizing agent, vitamin E has the function of eliminating free radical and reducing the free radical injury of antioxidant enzyme in sports, which can alleviate appearance of fatigue and improve sports ability. OBJECTIVE: Though the intervention of vitamin E upon exercise-induced muscle damage (EIMD), the study was designed to investigate the effect of vitamin E on the morphology of EIMD and to provide the experimental basis of research on morphology and mechanism of EIMD. DESIGN, TIME AND SETTING: A randomized block animal experiment was performed in the Key Laboratory of General Administration of Sport of China in Shenyang Sport University and the Microelectronic Laboratory of Chinese Medical University from May to October 2007. MATERIALS: A total of sixteen male Sprague Dawley rats were randomly divided into four groups: control, exercise, normal saline, and vitamin E groups. METHODS: The rats in the vitamin E group was administered (i.p.) 1-1.2 mg/kg vitamin E capsules once every eight hours four times one day before experiment, and the amount of injecting volume was 4 mL/kg. The rats in the normal saline group were administered (i.p.) normal saline with same volume and time. The rats in the exercise group only took some exercises without administering vitamin E or normal saline. The rats in the control group received not any intervention and treatment. The injury model was established by taking a bout of exhaustive downhill running. The triceps brachii muscles extracted from the right side of rats after exercise were prepared for electron microscope specimens. MAIN OUTCOME MEASURES: The arrangement of myofibrils and sarcomeres, the changes of Z-line, and the morphology changes of cell membranes, nucleus, mitochondria, sarcoplasmic reticulum, transverse tubule, and satellite cells were observed. RESULTS: In the vitamin E group, the muscular ultrastructures of EIMD were improved obviously. Though the sarcoplasmic reticulum showed edema, the regular arrangement of myofibrils was observed. The light and dark zone of Z-line and nucleus appeared clearly. CONCLUSION: Supplement of vitamin E could decrease the muscular morphological changes of EIMD after eccentric exercise. The arrangement of myofibrils was more regular and sarcomeres appeared more clearly. The function might relate to the antioxidation and promoting synthesis of proteins of vitamin E.

Objective To study the therapeutic effect of Danshen injection combined with conventional therapy on children with recurrent asthmatic bronchitis. Methods A prospective study was conducted. Fifty-five children with asthmatic bronchitis admitted in People's Hospital of Henan Province from January 2012 to July 2014 were enrolled and randomly divided into a integrative Chinese and western medicine group(30 cases)and a conventional therapy group(25 cases);in the same period,18 healthy children having passed physical examinations were chosen as the healthy control group. In the conventional therapy group,rest,oxygen inspiration,anti-infection, fluid supplement and aerosol inhalation,etc. were given,while in the integrative Chinese and western medicine group,based on the similar conventional therapies,additionally Danshen injection 0.4 mL · kg-1 · d-1 was given,once per day for a total of 14 days. The wheezing remission time and the pulmonary rale extinction time were observed in the two patient groups,and the fractional exhaled nitric oxide(FeNO)content was investigated in the three groups. Results The wheezing remission time and the pulmonary rale extinction time of the integrative Chinese and western medicine group were obviously shortened compared with those in the conventional therapy group〔the wheezing remission time(days):2.3±0.8 vs. 5.2±1.1,the pulmonary rale extinction time(days):6.8±1.5 vs. 8.4±1.1,both P<0.01〕. The contents of FeNO in the integrative Chinese and western medicine group and the conventional therapy group before treatment were significantly higher than those in the healthy control group(×10-9:30.3±9.5,30.4±8.2 vs. 13.6±3.4,both P<0.01),but after treatment the FeNO levels of both patient groups were markedly lowered,and the degree of change in integrative Chinese and western medicine group was more significant(×10-9:18.6±4.7 vs. 24.0±6.8,P<0.01). Conclusion Danshen injection combined with conventional therapy can obviously down-regulate the FeNO content,alleviate the airway inflammation,effectively relieve the children recurrence of asthmatic bronchitis.

BACKGROUND:Studies have found that β-casomorphin 7 can lessen oxidation of renal tubular epithelial cels and lower blood sugar in a rat model of diabetes. There is a few studies concerning the effect of β-casomorphin-7 on diabetic nephropathy. OBJECTIVE:To explore the effects of β-casomorphin-7 on renal injury in a rat model of diabetic nephropathy. METHODS:The 30 rats were equaly and randomly divided into control group, model group andβ-casomorphin-7 group. Twenty rat models of diabetes were established. In the model and β-casomorphin-7 groups, rats were intraperitonealy injected with streptozotocin (60 mg/kg). In the control group, rats were intraperitonealy injectedwith an equal volume of citric acid. Rats in the β-casomorphin-7 group were intragastricaly administeredβ-casomorphin-7 for 30 days. Rats in the model and control groups were given an equal volume of saline by intragastric administration. RESULTS AND CONCLUSION: (1) Compared with the control group, insulin levels decreased, glucagon, blood glucose, urine glucose, urine protein, serum creatinine, serum urea nitrogen levels, mRNA and protein expression levels of type I colagen and type IV colagen in kidney increased in the model group. (2) Compared with the model group, above indexes were apparently recovered in the β-casomorphin-7 group. These findings indicate that β-casomorphin-7 has a protective effect on renal injury in diabetic nephropathy rats.
