Objective To evaluate disinfectant efficacy of air disinfector and ultraviolet lamp.Methods Domestic literatures were searched by computer,RevMan 5 .3 software provided by the Cochrane collaboration was used for quantitative analysis,efficacy of two kinds of air disinfection methods was compared. Results A total of 1 1 articles met the inclusion criteria. Because the heterogeneity of literatures,random effects model analysis was adopted, colony forming unit (CFU)before disinfection(WMD= -26.28,95% CI:[-60.31,7.75],P>0.05 )and immediately-after disinfection(WMD= 22.45,95% CI:[-34.24,79.13],P>0.05)had no obvious difference between two methods respectively,but CFU of air disinfector 2 hours after disinfection was significantly less than ultraviolet lamp group(WMD= -345.11,95% CI:[-478.28,-211.94],P<0.05).Conclusion Air disinfector has good continuous disinfection efficacy.

Objective To explore the effect of Mycobacterium tuberculosis antigen (Mtb-Ag) on neutrophils apoptosis.Methods The fresh isolated neutrophils from healthy adults blood were cultured with Mtb-Ag for 24 h,with or without pretreatment of nuclear factor -?B (NF-?B) inhibitor N-tosyl-L-phenylanyl chloromethyl ketone (TPCK) for 30 minutes.Annexin V staining and Flow cytometry were used to measure cell apoptosis of neutrophils.NF-?B DNA binding was measured by gelelectrophorestic mobility shift assay (EMSA) in neutrophils after incubated with Mtb-Ag for 0,1,2,4,6,24 hours.Results Comparing to the spontaneous apoptosis (55%?6%) of neutrophils after culture in vitro for 24 h,treatment of Mtb-Ag (1.125 mg/ml) decreased the cell apoptosis of neutrophils (32%?3%).The NF-?B shift bands were detected at 1 h in neutrophils after stimulated by Mtb-Ag,and reached maximum peak at 2 hours,and then returned to basal levels within 24 h.Pretreatment of TPCK inhibited the anti-apoptosis role of Mtb-Ag in neutrophils.Conclusion Mtb-Ag prevents neutrophils apoptosis and its inhibitory role concerns NF-?B pathway.

Objective: To study the pharmacological effects of Zengxuean capsule (Radix Astragali, Indigo Naturalis, Cordyceps, etc) on anti inflammation.Methods:A few conventional models, such as the mouse pinna swelling induced by croton oil, were employed to determine the anti inflammatory activities of Zengxuean capsule.Results: Zengxuean capsule obviously inhibited the swelling of mouse pinna induced by croton oil, suppressed the edema of rat hind paw elicited by injection of 1% carrageenan, significantly depressed the increase of peritoneal capillary permeability in the xylene induced mice, and greatly decreased proliferation of granuloma led by implanting cotton pellet. It had an abatement effect of algesia induced by heat with tail flick method, and could not inhibit the swelling of pinna led by croton oil when mouse's adrenal was resected.Conclusion: Zengxuean capsule is an effective medicine on anti inflammation, and its acitivity is realized by adrenal cortical system.
