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.

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.

OBJECTIVE: To discuss the economic benefits of pharmaceutical care after hospital drug price addition has been cancelled. METHODS: To analyze the way to create economic benefits from hospital pharmaceutical services in China by drawing experiences from developed countries. RESULTS & CONCLUSIONS: Canceling of hospital drug price addition is conducive to the increase of the status of pharmacists. Medical institutions can profit from extending pharmaceutical services.

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 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 .
