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.

Thyptase,a predominant serine protease in mast cells,is released by mast cell degranulation in an enzymatically active form.Recent research suggests that ttyptase plays important roles in mast cell mediated anaphylaxis,angiogenesis,initiation and promotion of neoplasm.This paper reviews tryptase's struture,molecular biology,biochemistry,processing,activation and its relationship with diseases.

Objective To explore the effectiveness of ω-3 fatty acids in intervening rat models of chronic obstructive pulmonery disease (COPD).Methods The rat COPD models were established by cigarette smoking and intratracheal lipopolysaccharide instillation.Totally 90 rats were randomly divided into 3 groups:normal control group (treated with normal saline),COPD group,and intervention group (the COPD rat models treated with ω-3 fatty acids).Lung tissues were obtained on the 7th,21st,and 28th day.The left lower lobes were analyzed to determine the expressions of nuclear factor-kappa beta (NF-κB) and interferon-γ (IFN-γ)and the right lung lobes were sliced for detecting the cell apoptosis.Double antibody sandwich enzyme-linked immunosorbent assay (DAS-ELISA) was used to detect the serum IFN-γ and interleukin-6 (IL-6).Results (1) The pathological changes of lung tissue:there were a large number of inflammatory exudation,alveolar wall thickening,hyperplasia of vascular smooth muscle and the alveolar structure destruction in the COPD model group,but the lung tissue were part of alveolar cavity and a little inflammatory exudate in ω-3 fatty fish acids treatment group,control rats were almost no alveolar inflammation on the 28th days.(2) On the 28th day,NF-κB protein expression of the lung tissue (18.91 ± 3.07) in rats of COPD model group was significantly higher than the control group and the intervention group (5.47 ±4.86 and 7.23 ±2.21) (P ＜0.01).On the 28th day,IFN-γ protein expression in lung tissue of the rats in the model group was 7.12 ±3.37,significantly lower than the intervention group (18.74 ± 2.65),the difference was statistically significant (P ＜ 0.01).(3) The IL-6 levels of the blood-serum of model group rats were (13.43 ± 2.47) ng/L,significantly higher than the control group and the intervention group [(4.78 ± 1.93) and (4.98 ± 1.89) ng/L],the differences were statistically significant (P ＜ 0.01) on the 28th day,,but the IFN-γ level [(2.23 ± 0.63) ng/L] in COPD group was more poorer than ω-3 fatty acids group and the intervention group [(4.51 ± 0.71) and (7.05 ± 0.52) ng/L] (P ＜ 0.01).Conclusions The ω-3 fatty acids can lower NF-κB protein expressions in lung tissues and serum and IL-6 levels in COPD rats; aslo,it can increase the IFN-γ protein expression in lung tissue and serum.Thus,it can prevent the lung inflammation in COPD rats.

ObjectiveTo compare the effectiveness of ω-3 fatty acids and middle/light fatty acids in the intervention of rats model of bleomycin-induced pulmonary fibrosis.MethodsTotally 120 rats were randomly divided into 4 groups: normal saline (NS) group,bleomycin-induced pulmonary fibrosis without treatment group ( BLM group),middle/light fatty acids group,ω-3 fatty acids group.Lung tissues were obtained on the 7th,14th,and 21st day after modeling.The left lung were measured by using immunohistochemical methods for transforming growth factor β1 (TGF-β1) and interferon garmma ( IFN-γ).The lower lobe of the right lung underwent HE staining.Serum TGF-β1,IFN-γ,and interleukin-4 (IL-4) were measured using double-antibody sandwich ELISA.ResultsThe pulmonary alveolitis and fibrosis in the ω-3 fatty acids group was significantly milder than in middle/light fatty acids group and BLM group.On the 7th,14th,and 21st day after modeling,stronger TGF-β1 protein expression was detected in the bronehiolar epithelia of middle/light fatty acids group and BLM group and poorer IFN-γexpression in both groups.However,the opposite results were found in the ω-3 fatty acids group: on the 7th,14th,and 21st day after modeling,TGF-β1 protein expression ( 13.60 ± 5.90,10.53 ± 4.21,and 7.23 ± 2.21 )was lower ( P =0.047) and IFN-γ ( 13.85 ± 7.48,15.32 ± 2.12,and 18.74 ± 2.65 ) was stronger in ω-3 fatty acids group (P =0.041).On the 7 ,14,and 21st day after modeling,the serum IL-4 levels in the middle/light fatty acids group and BLM group became significantly higher,while the IFN-γ level in both groups was significantly lower than in ω-3 fatty acids group ( P =0.008 ) ; meanwhile,in the ω-3 fatty acids group,the serum IL-4 levels [ (8.73 ± 1.20),(5.73 ±2.03),and (4.98 ± 1.89) pg/ml] were significantly lower (P =0.044) and serum IFN-γlevels [ (5.67 ± 0.13 ),( 6.58 ± 0.64 ),and ( 7.05 ± 0.52 ) pg/ml ] were significantly higher ( P =0.048 ) on the 72,14th,and 21st day after modeling.Conclusionsω-3 fatty acids can lower TGF-β1 protein expression in rat lung tissue and reduce the surum TGF-β1 and IL-4 levels.Compared with the middle/light fatty acids,it can more effectively upregulate the expression of IFN-γ in lung tissue and increase its serum level,and thus alleviate pulmonary fibrosis in rats.

To summarize the present situation of research on amylolytic lactic acid bacteria and its amylase,and the fermentation technology of amylolytic lactic acid bacteria.The amylolytic lactic acid bacteria have the ability of secreting amylase,can direct ferment starchy material into lactic acid without hydrolysising processes,simplify the production process,and saving the equipment investment,thereby,decrease the cost of production.Amylolytic lactic acid bacteria isolated from traditional fermented food,or from organic waste and kitchen waste.The mechanism of direct utilize starch raw materials by the amylolytic lactic acid bacteria were introduced,the fermentation technology of amylolytic lactic acid bacteria were compared.Meanwhile it was pointed out that through mutation breeding and genetic engineering methods gain the potent amylolytic lactic acid bacteria,and use the advanced fermentation and separation technology can improve the productivity of lactic acid.

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 .
