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 evaluate the medical efficiency of sample hospitals in Sanming city before and after Sanming health care reform.Methods One tertiary hospital,two general county hospitals and two TCM county hospitals in Sanming were sampled for the study.Two dimensions(the intensity index of medical work and work efficiency index)were selected.In addition,six indexes were identified,namely the number of discharged patients,number of outpatients and emergency diagnostics,doctor′s daily workload per capita for inpatients,bed turnover times,bed utilization rate and average days of stay.Descriptive trend analysis and comprehensive index method were applied in turn to evaluate the longitudinal changes in medical efficiency at the sample hospitals before and after the medical reform.Results The five sample hospitals in Sanming were found with less days of stay in average,and three were found with year-by-year rise of medical efficiency index,with one of them rising from 1.57 to 2.42.Conclusions Sanming′s health care reform has effectively improved internal operational efficiency at the sample hospitals,and has well addressed the relationship of medical service efficiency and scale expansion.On the other hand,the relationship between work intensity and medical efficiency needs to be further balanced,resource allocation to be further optimized,and more priority to be put in the development of TCM hospitals.

Objective To study the effect and mechanism of Erzhi Tiangui Granule(Granule for promoting the uterine functions) on infertility induced by luteal phase deficiency.Methods Sixty infertility patients owing to luteal phase deficiency were randomized into the tested group(treated with Erzhi Tiangui Granule) and the control group(treated with Liuwei Dihuang Granule),30 in each.The improvement of TCM symptoms,the serum levels of estradiol(E2) and progestone(P),the expression of leukemia inhibiting factor(LIF) of luteal metaphase before and after treatment,and the pregnancy rate were observed.Results After treatment,the tested group was significantly better than the control group in improving the TCM symptoms(P0.05);the pregnancy rate in the tested group was higher than that in the control group(P

Objective To investigate the usefulness of urapidil in the management of high risk cardiac patients undergoing emergency noncardiac operation Methods 20 cardiac patients (male 11, female 9) scheduled for emergency noncardiac surgery were included in this study The age averaged (54 1?16 5) years The heart diseases included pregnancy induced hypertension(PIH) complicated with congestive heart failure(CHF) in 5 patients, coronary artery heart disease in 7, hypertensive heart disease in 4 and rheumatic heart disease in 4 Functionally they were classed as Ⅱ or Ⅲ according to New York Heart Association(NYHA) classification 40 healthy blood donors served as normal control In operating room before anesthesia the patients were given an intravenous bolus of urapidil 0 4 mg kg -1 Venous blood samples were taken before and 15 min after intravenous administration of urapidil for determination of plasma concentration of endothelin (ET) neuropeptide Y (NPY) and calcitonin gene related pepitide (CGRP) by radioimmunoassay Results Plasma concentrations of ET and NPY were significantly higher and CGRP was significantly lower in high risk cardiac patients than normal control values 15 min after urapidial ET and NPY decreased significantly (P

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 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.
