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.

Objective To select the optimum extracting method of polysaccharide from Paris polyphylla Smith var. chinensis(Franch. )Hara in Shaan'xi. Methods The optimum extraction technology and condition were determined by using response surface methodology and single factor experiment,with the extraction ratio of polysaccharides from Paris polyphylla Smith var. chinensis( Franch. ) Hara in Shaan'xi as indicator. Results The optimum extraction condition for the polysaccharides was as follows:extracting at 92 ℃ for 2. 6 h and with the liquid to solid ratio of 15 ( mLg). The average extraction yield of polysaccharide was 3. 22%under the optimum extraction condition. Conclusion The method is suitable for the extraction and determination of polysaccharides from Paris polyphylla Smith var. chinensis( Franch. ) Hara in Shaan'xi.

Objective To study the effects of endolymphatic sac decompression and on semicircular canal plugging in treating intractable Meniere's disease.Methods A total of 14 cases of intractable Meniere's disease were included in this study.The age was from 33~67 years old and the history was from 1 to 40 years.The hearing level of bone was from 35 to 65 dB for the speech frequencies.All cases received the treatments according to the pre-op-erative design.The endolymphatic sac was decompressed and the three semicircular canal bones were drilled to cre-ate a fenestra followed by soft tissue plugging into the canal.The vertigo,hearing level and tinnitus were included in the following up.Results All cases had no facial palsy,no cerebrospinal leak,and no vertical after surgery.In the period of 3 to 18 months following up,the attack of Meniere's disease was completely controlled for 13 cases excep-tion of one lost case.For five cases,the hearing level descended 10 to 15 dB compared to pre-operation.Conclusion Although the endolymphatic sac decompression can relieve endolymphatic pressure,this may not adequately pro-tect the hearing caused by the semicircular canal plugging.The surgical technique is reliable and safe;however fur-ther clinical data should be gathered.

As a clean, efficient, and renewable energy, hydrogen is regarded as a promising alternative. Because of using biomass as substrate, microbial fermentative hydrogen production can meet the need of sustainable development. The factors affecting the process of microbial fermentative hydrogen production, are analyzed in this paper on the basis of microorganisms, substrates, products and operative parameters. The parameters related to hydrogen production from organic wastes, are also mentioned.

Aim To study the actions of Luofendeine and its component. Methods LD50 tests of Luofendeine and its component, heat_board text and body_twisting test of mice were pertormed to learn its analgesic and antiinflammatory actions. Results The analgesic action and antiinflammatory action were increased when codamine was mixed with buluofen by the rate of 13∶200,without increasing its toxicity. Conclution The complex prescription of Luofendeine is rational and can increase the analgesic action obviously.

Objective To evaluate the effect on treatment of multiple myeloma complicating femoral neck fracture by surgical intervention combined with drugs.Methods Twelve patients with multiple myeloma complicating femoral neck fracture were treated by cemented total hip arthroplasty femoral head shank.All of patients were received zoledronic acid treatment,at the same time,7 cases of them treated by MPT regimen (melphalan,methylprednisolone and thalidomide),3 by bortezomib combined with dexamethasone,and 1 by autologous peripheral blood stem cell transplantation.Results Twelve patients could tolerate surgery,postoperative pain was significantly reduced.Assessed by using Harris hip function score after 6 months operation,2 cases were excellent,7 cases were good,3 cases were common,excellent and good rate was 75％ (9/12).All patients were followed up for 8 months to 3 years,1 case of local recurrence after 13 months.1-year overall survival rate was 100％,2-year overall survival rate was 83％,and 3-year overall survival rate was 67％.Conclusions Multiple myeloma complicating femoral neck fracture,using bone cement in total hip arthroplasty femoral head shank to clear the local tumor lesions,receive reconstruction capability,rapid postoperative recovery,pain relief,and opportunities for further comprehensive treatments.The bisphosphonate can promote new bone formation and prevent further fractures.The surgical intervention combined with chemotherapy could relieve the symptoms,reduce tumor cell burden,improve quality of life and prolong survival time.

Objective To investigate the association of two functional polymorphisms of tryptophan hydroxylase 2(THP2) gene,rs4570625 and rs4565946,with poststroke anxiety disorders.Methods Totally 112 poststroke anxiety patients and 246 non-anxious stroke controls were included and completed Hamilton Anxiety Rating Scale.DNA was extracted from blood and genotyped for the two polymorphisms of THP2 gene by polymorphism chain reaction.Results The G allele of rs4570625 was associated with the increased risk of poststroke anxiety.Both the GG genotype and G allele were observed to be significantly higher in female case than in control.No significant difference in genotype and allele firequencies of the rs4565946 was found among the groups.Patients with the G-C haplotype had significantly increased the risk of poststroke anxiety compared to controls.Conclusions Our findings suggest that these ftmctional polymorphisms in TPH2 gene may be involved in development of poststroke anxiety.
