Objective:To discuss the important significance of the archival management for special equipment of hospital, and to ensure life safety of employee and patients of hospital. Methods: Through summarized practice experience in work, the content, existed problem, the relative management activity and solution of archival management of special equipment of hospital were analyzed and researched.Results: The development of archives management for special equipment of hospital must comply with the development of era. The traditional thinking model of management for equipment archival was transformed. And the advancedtechnique was applied to constantly improve and update the archival management of special equipment of hospital. And then the classification management, standard preventions and working process achieved more standardization, more science and more preciseness.Conclusion:The improved archival management of special equipment can ensure special equipment to play its due role in the diagnosis and treatment of hospital.

The identification and classification of Thermus to Thermales is revie wed. Up to now, the order Thermales is consist of only one family Thermaceae, w h ich includes 4 genera with 14 valid species about 50 strains, and with 4 unvalid spcecies and more than 50 strains unidentified. The morphology, physiology, G+ C mol%, DND hybridization, fatty acid components, 16S rRNA alignment and secondar y structure analyses have been tools for the taxonomy of Thermales.

Objective To evaluate the effects of isoflurane anesthesia on NR1 expression and neuronal apoptosis in the hippocampus and cortex of adult rats .Methods Thirty-six adult male Sprague-Dawley rats , weighing 250-280 g ,were randomly assigned into 3 groups using a random number table :control group (group C , n=6 ) ,O2 inhalation group (group O , n=6 ) and isoflurane anesthesia group (group I , n=24 ) .The rats were exposed to 2% isoflurane (group I) ,to pure oxygen (group O) ,or to air (group C) for 2 h .At 2 h ,and 1 ,7 and 14 days after the rats were awake (T1-4 ) ,Morris water maze test was performed .The rats were then sacrificed and brains were removed for isolation of the hippocampus and cortex .NR1 expression was detected using SABC immuno-histochemical technique and neuronal apoptosis was determined using TUNEL .Results Compared with group C , the escape latency at T2 and total swimming distance at T1 ,2 were significantly prolonged , and the expression of NR1 in hippocampi was down-regulated at T1 ,2 in group I ,and the expression of NR1 in the cortex was down-regulated in O and I groups ( P<0.05) .There was no significant difference in the apoptosis index between the three groups ( P> 0.05 ) .Conclusion Isoflurane anesthesia can decrease the cognitive function transiently ,which is related to inhibition of up-regulation of NR1 expression in the hippocampi ,but not related to neuronal apoptosis in adult rats .

ObjectiveTo investigate the mechanism of protective effect of Xuebijing injection on vascular endothelial cells in rats with heat stress.Methods Ninety Sprague-Dawley(SD) rats were randomly divided into control, model and Xuebijing injection treatment groups, 30 rats in each group. Heat stress model was reproduced by placing rats in constant temperature box at 40℃, 60% relative humidity for 1 hour, Xuebijing injection group was treated by intraperitoneal injection of Xuebijing 2.5 g/kg, while the control and model groups were treated by intraperitoneal injection of normal saline 2 mL/kg, once a day only in 1 day for both groups. After model establishment, the rectum temperature, heart rate and the mean arterial pressure(MAP) were recorded at 2, 6, 12 hours in each group. At the same time, the rat abdominal aortic blood was collected and serum was separated, the enzyme-linked immunosorbent assay(ELISA) was used to determine the aortic serum levels of lipopolysaccharide(LPS), nuclear factor-κB(NF-κB) and p53, and the prothrombin time(PT), activated partial thromboplastin time(APTT) and D-dimer of venous blood were detected by automatic blood coagulation analyzer(ACLTOP).Results Compared with those in control group, the rectum temperature, heart rate, LPS, NF-κB, p53, PT, APTT, D-dimer were significantly increased, and MAP was obviously decreased in model group(P<0.05 orP<0.01). Compared with model group, the above indexes were improved significantly in Xuebijing injection treatment group at 2 hours〔rectum temperature(℃): 38.02±0.22 vs. 39.32±0.33, heart rate(bpm): 507±14 vs. 562±35, MAP(mmHg, 1 mmHg=0.133 kPa): 98±6 vs. 87±13, LPS(ng/L): 0.65±0.03 vs. 0.82±0.05, NF-κB(ng/L): 1.10±0.04 vs. 1.33±0.05, p53(ng/L): 1.33±0.03 vs. 1.73±0.02, PT(s):15.47±1.03 vs. 20.28±2.01, APTT(s): 40.26±2.46 vs. 47.46±3.51, D-dimer(μg/L): 238.54±8.32 vs. 323.12±8.14,P<0.05 orP<0.01〕.Conclusion Xuebijing injection can correct the disorders of blood PT, APTT, D-dimer via decreasing the secretion of the levels of NF-κB, p53 from vascular endothelial cells in rats with heat stress, thus the integrity of the vascular endothelium can be protected, and LPS entering into the blood stream can be inhibited.

Objective To study the effectiveness of subfascial endoscopic communicating branch vein ablation in treating communi cating branch vein insufficiency.Methods Fifty-seven cases of primary lower ext remity vein valve insufficiency complicated by communicating vein insufficiency diagnosed by venography and color duplex were treated with subfascial endoscopic communicating branch vein ablation, and their information was analyzed retrosp ectively.Results Swelling was observed in leg of 7 cases after operation, and disappeared within one week spontaneously. Incision infec tion occurred in 2 cases and skin ambustion happened in 2 cases. Superficial vei n varicosis disappeared in all case, skin pigmentatin declined significantly and ulcers healed in 2-3 weeks.Conclusion Subfascial endoscopic communicating branch vein ablation is an excellent choice in treating communicating branch ve in insufficiency.
