Objective To improve the resistance exercise apparatus of climbing ladder with load on rats, and to observe the technological, athletic training and biological response to the improved experimental apparatus.Methods Thirty-six healthy SPF male Sprague-Dawley were randomly divided into control and exercise groups.The climbing ladder and weight bearing device were separately improved to develop a new resistance exercise apparatus of climbing ladder with load on rats.The exercise group took an 8-week incremental exercise program using this improved device.To observe the operation effect of this improved exercise apparatus.To observe the dynamic changes of average maximum load on SD rats from the exercise group during 8 weeks.To compare the effect of climbing ladder exercise with load on body weights of SD rats between the two groups.Results The improved climbing ladder was marked by the prioritization technique of architecture stabilization, weight bearing and easy cleaning.The improved bearing device has the advantages of being sturdy and durable, and simplemethod to calculating load.Moreover, the new experimental apparatus can be operated by one person during the exercise program.The average maximum load was successfully increased to 756 g after an 8-week exercise using the improved apparatus.Compared with the control group, the body weights of SD rats from the exercise group after training were significantly reduced (P<0.05).Conclusions The improved resistance exercise apparatus of climbing ladder with load can provide a more endurable and repeatable process in the study of rat strength training and it is recommended to use this new device in future experimental research.

Objective To determine the content of anabasine in Fengshiding tablets.Methods RP-HPLC method was established.Diamonsil-C18 was used as chromatographic column,the mobile phase consisted of methanol and 0.1 %triethylamine(5 ∶95,adjust pH to 3.6 with H3PO4),the flow rate was 1.0 mL?min-1 and the detection wavelength at 259 nm.Results The average recovery for Anabasine was 99.0 %,RSD=2.8 %(n=6).Conclusion The method can be used to determine the content of anabasine in Fengshiding tablets.

Objective To observe the effect of Wenxiao Granule on the expression of MCP-1 and TNF-? in experimental atherosclerosis rabbit, and explore its mechanism in treating atherosclerosis. Methods Thirty-six New Zealand rabbits were randomized to four groups: control group, Wenxiao granule group, Simvastatin group. They were fed a high-fat diet except normal group until the mature atherosclerotic plaques formed. The rabbits in two drug-treated groups were treated with respective drug for 8 weeks. All rabbits were sacrificed. The morphology and composition of atherosclerotic plaques in aortic roots were examined. The expression of MCP-1 and TNF-? were determined by immunohistochemical staining. Results The expression of MCP-1 and TNF-? in plaque of Wenxiao Granule group and simvastatin group were significantly dereased compared with the model group (P 0.05). Conclusion Wenxiao Granule can inhibit the expression of MCP-1 and TNF-?, which may stabilize plaque of atherosclerosis.

Objective To study the diagnostic value of TREM-1,PCT and CD64 in children with sepsis disease and its effect on the application of low dose hormone.Methods 80 cases children with septic disease who received therapy from September 2014 to September 2016 in the third affiliated hospital of wenzhou medical university,28 cases of severe sepsis disease,52 cases of general sepsis disease,and selected 40 cases of healthy children in our hospital during the same period,the levels of TREM-1,PCT,CD64 of three groups were compared.And through the random number table method,those 80 cases children with sepsis disease were divided into the observation group(n=40) and the control group(n=40),the control group was treated with routine treatment,while the observation group was treated with hydroprednisone on the basis of the control group,after treatment for seven days,the levels of TREM-1,PCT,CD64 of two groups were compared.Results The levels of TREM-1, PCT and CD64 in the severe sepsis disease group and general sepsis disease group were higher than the healthy group(P<0.05),and the levels of TREM-1, PCT and CD64 in severe sepsis disease group were significantly higher than the general sepsis disease group(P<0.05).After treatment,the levels of TREM-1,PCT and CD64 were improved in two groups of patients with sepsis disease(P<0.05),after treatment of one day and seven days,the levels of TREM-1,PCT and CD64 in observation group were lower than in the control group(P<0.05).Conclusion TREM-1,PCT,CD64 levels can be used as early detection in children with sepsis disease,low dose glucocorticoid can effectively reduce the expression of TREM-1,PCT and CD64 levels in children with sepsis,it's conducive to the disease control.

Objective To observe the effect of Yinhuang freeze-dried powder injection on nervous system of rats and mice,and to probe its safety.Methods After injected Yinghuang freeze-dried powder injection nerve system and general behavior of rat or mouse were observed.Results Yinghuang freeze-dried powder didn’t affect rat’s or mouse’s general behavior,but had certain central nevous system suppression function in rats and mice.Conclusion Yinghuang freeze-dried powder have certain central nevous system suppression function in rats and mice.

Objective To observe the rat chronic toxicity induced by Yinghuang freeze-dried powder injection. Methods The rats were given Yinghuang freeze-dried powder injection for 35 days with the doses of 166.5, 82.25, 41.12 mg/kg and for 15 days of stopping administration. The index sign of hematology and biochemistry were determined, and the pathological examination were carried out. Results The rat were given Yinghuang freeze-dried powder injection for 35 days and for 15 days of stopping administration. Mostly index sign of hematology and biochemistry had no significant difference by comparing with the control. There exceptional index sign of exceptional dosage group have significant difference by comparing with the control. But these exceptional index sign fluctuated in normal range in the laboratory. The pathological examination did not discover significant pathological changes related to drug toxicity. Conclusion Yinghuang freeze-dried powder injection has no significant toxicity for long-term administration on rats. It infers that the drawing up doses in clinic will be safe.
