Neuronal apoptosis is one of the important forms of neuronal death in ischemic stroke.N-methyl-D-aspartate (NMDA) receptor-mediated excitatory amino acid toxicity plays an important role in neuronal apoptosis. It is the initiator and executor of apoptosis in neuronal cells. NR2B is the major regulatory subunit of this receptor, its transmembrane segment M2 is a reflexed membrane loop region facing cytoplast toward intramembrane, forming the inner wall of ion channel, which determines the permeability of the NMDA receptor ion channel to calcium. Glutamate mediates cell injury mainly through calcium overload, therefore, NR2B subunit plays a vital role in the neuronal apoptosis in ischemic stroke.

Objective To investigate whether acupuncture can prevent postoperative nauseaand vomiting (PONV)in patients received breast surgery. Methods Two hundred and forty patients were randomly divided into the acupuncture group and the control group. Patients in the acupuncture group were treated at bilateral Hegu (L4) and Neiguan (P6) after surgery. Patients in the control group received no any interventions. The occurrence of postoperative nausea and vomiting, the number of complete remission and the remedial treatment were record ed. Results The incidences of nausea and vomiting in the acupuncture group were lower than those in the control group from 2 h to 6 h post-operation, with less need of remedy treatment (P < 0.05, respectively). Conclusion Acupuncture in preventing nausea and vomiting after breast surgery owns a certain value in the early postoperative (6 h) stage, with effectively reducing the occurrence of postoperative nausea and vomiting.

Klebsiella Pneumoniae is an important pathogen for various infections clinically,in which hypervirulent Klebsiella pneumoniae (hvKP) mainly causes pyogenic liver abscess.By now,there are no standardized method to identify hvKP strains.hvKP strains are usually with hypermucoviscous phenotype,and the prevailing serotypes and clonal types are K1,K2 and CC23,CC65,respectively.Genes rmpA,magA,alls and kfu contribute to the pathogenicity of hvKP.This paper reviews the identification,clonal types and serotypes,hypermucoviscous phenotype and some other virulent genes of hvKP.

Objective Exploring different strengthening immune strategy on long-term immune memory effects for tuberculosis vaccine lays the theoretical foundation.Methods The fusion protein AMM,adjuvant DDA and BCG-PSN mixed built AMM subunit vaccine.Choose only 50 C57BL/6 mice (SPF),according to the table of random number method was divided into 5 groups and each group 10 only,the experiment 1 group injected mice to phosphate buffer solution (PBS) as control; Experiment 2 mice only injected BCG vaccine (BCG) from early; Experiment 3 mice BCG initial free,in 10 weeks with AMM subunit vaccine strengthen immunity; The four mice from early after BCG,respectively on 8 weeks,10 weeks with AMM subunit vaccine strengthen immune mice one time.Experimental 5 groups of mice after BCG initial free,respectively on 6 weeks,8 weeks,10 weeks with AMM subunit vaccine strengthen immune mice a.28 weeks to remove spleen lymphocytes in mice,add 2.5μg/ml Ag85B stimulus 72 h after collecting spleen cell culture supernatant,with ELISA test Ag85B specificity splenic lymphocyte caused IFN ppar-gamma level.Results Spleen cells by antigen Ag85B stimulation,BCG initial free,AMM subunit vaccine strengthen immune once,twice,three times group and PBS compared all had difference (P ＜0.01 orP ＜0.05) ;BCG initial free-AMM subunit vaccine strengthen immune once,twice,three times group and BCG compared all had difference (P ＜0.01 or P ＜0.05) ; BCG initial free-AMM subunit vaccine strengthen immune once and twice or three times group compared with difference (P ＜0.01 orP ＜0.05) ; Initial free-AMM subunit vaccine strengthen immune two group and three times than group difference was statistically significant (P ＞0.05).Conclusion Mice strong immune strengthened the number is not the more the better,the appropriate number of strengthen the immune to induce the most lasting immunity memory,subunit vaccine strengthen immunization strategy may affect the immune memory is one of the important factors.

Objective A traditional Chinese medicine (TCM) inheritance assist system software was used to analyze the medication experiences of treating urticaria.Methods Literatures in three TCM medical books about the treatment of urticaria were collected and analyzed in terms of the utilizing frequency and association rules between different medicines. Data mining research methods such as Apriori algorithm, complex system entropy cluster and unsupervised hierarchical cluster were used in the research.Results Based on 138 screened prescriptions, the study confirmed that the frequency of using Radix sileriswas was highest, and 20 drugs elected in 218 prescription drugs were used more than 20 times. According to the utilizing frequency order of pharmaceutical compositions from high to low, association rules between drugs ranked in the top four were‘ Radix sileris- Cicada slough’, ‘Radix sileris- Schizonepeta’, ‘Radix sileris- Paeonia’, and ‘Schizonepeta- Cicadaslough’. Meanwhile, 30 pharmaceutical drug combinations and 14 new prescriptions were found. Conclusion The research, based on TCM inheritance assist system software platform and data mining method on medication rules of urticaria treatment prescriptions, is instructive in the clinical treatment of urticaria and also provide useful reference for the development of the new drug on urticaria.

Objective: To study the protective effect of anti-tumor necrosis factor-?antibody (TNF-? Ab) on lung injury after cardiopulmonary bypass(CPB). Methods: 20 patients with valve diseases underwent valve replacement under CPB. The patients were randomly divided into two groups: control group and TNF-? Ab group. In the TNF-? Ab group, human TNF-? Ab was dropped into the intracheal tube before operation and just after releasing the aortic clamp, respectively. Lung dynamic compliance, blood neutrophils count and TNF-? from the right and left atrium were determined perioperatively. Results: The dynamic compliance of the lung in TNF-? Ab group was higher than that in control group. TNF-? Ab can reduce releasing of TNF-? and restrain leukocyte accumulation in the lung. Conclusion: TNF-? Ab has markedly protective effect on lung injury after CPB.

Objective To investigate the effects of neurotrophics and rehabilitation on the neural function recovery after the hypoxic-ischemic brain injury in rats. Methods Model rats of hypoxic-ischemic brain injury were given monosialotetrahexosylganglioside sodium(GM1, n=8), mouse nerve growth factor (NGF, n=8), both drugs (n=8), rehabilitation (n=8), both drugs+rehabilitation (n=8) and control (nointervention, n=8). The other 7 rats was as sham group. They were assessed with hanging and inclined plane test when 30 days old. ResultsIn the factorial design, main effect of GM1 was significant (P<0.05) but NGF (P>0.05) in hanging test; while both were significant in inclinedplane test. The interaction was not significant (P>0.05) in both tests. The main effects of drugs and rehabilitation were significant (P<0.05), as well as the interaction (P<0.05) in both tests. Conclusion GM1 may significantly improve muscle strength, voluntary movement,balance and coordination functions, and NGF may improve the balance and coordination functions. No interaction is found when combinedwith the two therapies.
