Objective To discuss the safety management of hemodialysis equipment for safe and effective treatment to patients.Methods The management methods were summarized in aspects of the installation,utilization and maintenance of hemodialysis equipment.Results The hemodialysis patients received the safe and effective treatment through the strict management and the standardized system.Conclusion The standardized management can not only reduce the unnecessary failures of the equipment,and prolong the service life,but also increase the utilization rate of the equipment,and provide the best,safest and most satisfactory treatment for patients.

10 cm respectively from the tumor),the metastatic rate of lymph nodes was 34.7%,2.5% and 1.7%,respectively.The metastatic rate of LN in right colon was significantly higher than that in left colon(52.0% vs 33.8%,P

Objective To investigate effects of cerebral isehemic preconditioning on neurological function,in- farct volume,and the expression of caspase-3 in brain issue after brain ischemia again,and to investigate the brain protection mechanism produced by cerebral ischemia preconditioning.Methods 48 healthy male Sprague-Dawley (SD)rats(weighted 200～250g)were randomly divided into 2 groups:ischemia group(n=24),ischemia precondi- tioning group(namely preconditioning group,n=24).Each group was divided into 4 subgroups according to 6h,1d, 2d,4d after ischemia again.Results At the same point of time after ischemia,neurological deficit in preconditioning group was much less than that in ischemia group,the difference was significant(P

BACKGROUND:The long-term contraction of skeletal muscle can lead to the decrease of resting potential, affect its contraction, and result in the occurrence of fatigue. Whether acupuncture and injury-free magnetic lifting needle are effective on the recovery of resting potential? OBJECTIVE: To observe and compare the influence on the recovery of resting potential of skeletal muscle by taking acupuncture and magnetic needle as the recovery means.DESIGN: A controlled study.SETTINGS: College of Physical Education, Shanxi Normal University;Binzhou College of Shandong Province.MATERIALS: Thirty experimental toads, which were provided by Beijing University of Physical Education, were randomly divided into acupuncture group (n=10), magnetic needle group (n=10), magnetic needle+pressing group (n=10). Left and right semitendinosus muscles were taken as controls.METHODS: The in vitro toad's semitendinosus muscles (experimental side and control side) were treated with electrostimulation for 40 minutes,and then the resting potential of skeletal muscular cells were measured with the intracellular glass microelectrode technique. After the electrostimulation, filiform needle acupuncture, magnetic needle, magnetic needle plus pressing were also given.MAIN OUTCOME MEASURES: The resting potentials were observed before exercise, after electrostimulation and other treatments in the groups.RESULTS: ① The resting potentials of skeletal muscular cells after electrostimulation were decreased as compared with those before electrostimulation [experimental side: (59.48±7.37), (84.54±5.72) mV; control side:(59.43±7.14), (83.62±5.86) mV]. ② After the treatments of acupuncture,magnetic lifting needle, magnetic lifting needle plus pressing, the decreased resting potentials after electrostimulation were obviously recovered (P ＜ 0.01). ③ The recovered percentage of resting potential in the magnetic needle group was obviously smaller than those in the acupuncture group and magnetic needle+pressing group [(42.50±12.41)%, (53.71±10.93)%,(49.10±8.39)%, P ＜ 0. 01].CONCLUSION: Acupuncture, magnetic lifting needle, magnetic lifting needle plus pressing plays a role in promoting the recovery of resting potential of skeletal muscular cells after long-term electrostimulation, and the effect of simple magnetic needle is smaller than that of acupuncture and magnetic needle plus pressing.

Objective To investigate the clinical effect of ultrasound-guided sclerosing therapy with injection of lauromacrogol for the treatment of pelvic encapsulated hydrops. Methods A total of 40 patients with pelvic encapsulated hydrops were enrolled in this study. Under ultrasonographic guidance , puncture aspiration of pelvic encapsulated hydrops was carried out in all patients , which was followed by lauromacrogol injection of appropriate dose, and the drainage catheter was kept in the hydrops cavity. The clinical results were evaluated at one, 2 and 3 months after the treatment. Results The success rate of puncturing was 100%. Six months after the treatment, the complete cure was obtained in 86.4%of patients, and the effective rate was 100%. Conclusion For the treatment of pelvic encapsulated hydrops , ultrasound-guided sclerosing therapy with injection of lauromacrogol is effective and safe with instant result and lower recurrence rate. Therefore, this technique should be recommended in clinical practice.

The development of the endocardial cushion and the ventricular septum of chicken heart was studied with SEM, TEM, light microscopy and histochemical methods. The results are as follows:1. The development of endocardial cushion begins from the proliferation of the endothelial cells which form cushion cells when these cells enter the cardiac jelly. Cushion cells also proceed mitosis and migrate toward the myocardium, and the endothelial cells cease proliferation when the reserve layers of cushion cells were formed. The fused endocardial cushion participates in the formation of atrioventricular orifice, the right tubercle prolongs toward the ventricular septum and eventually fuses with it.2. The cardiac jelly of endocardial cushion contains a great deal of hyaluronic acid which arranges in "trails", pioneering cushion cells migrate along the "trails" and change the component and arrangement of the matrix.3. Muscular ventricular septum is formed by aggregation of trabeculae inside the interventricular sulcus. The dorsal part of the ventricular septum fuses with the lower part of right tubercle of endocardial cushion and the ventral part fuses with the conus septum.

The morphogenesis of the heart and the formation of the epicardium were studied with SEM, TEM and light microscopy. The results are as follows:1. There are two stages in the development of chicken heart: First is the formation of cardiac loop. In certain places, the sulcus appears outside, and the cresta appears inside during this stage. The formation of the cardiac loop indicates the establishment of the anlagen of the heart; Second is the differentiation of the anlagen, including the septation of the heart and the shift of each part of the heart. The shift of the atrium and the conus results from the shift of the right and left ventriculum. 2. The epicardium is not differcntiatcd from the myocardium, but formed from the mesenchymal cells which proliferate in front of the sinus venosus. These cells migrate and cover the entire surface of the myocardium.
