OBJECTIVE:To explore how to establish good procedure,system and mode of drug management,dispensing and application,in order to provide reference for risk management and rational use of rabies vaccine. METHODS:The use of rabies vaccine and storage temperature monitoring in our hospital during 2013-2014 were analyzed statistically,and risk management and use of rabies vaccine in our hospital were analyzed,and management measures and attentions were put forward. RESULTS:The amount of vaccinum rabiel (Vero cell) and human rabies immunoglobulin in our hospital were increased in 2014,compared to 2013. The position labeled with #1 in storehouse and that of labeled with #1 and #2 in dispensing store could meet the storage condi-tion of rabies vaccine. Risk management could be carried out in fields of drug requisition,cold chain management,drug manage-ment and drug dispensing. ADR should be paid attention. CONCLUSIONS:It is of significance to develop risk management and ra-tional medication guidance of rabies vaccine.

Objective To observe the therapeutic effect of electroacupuncture combined with rehabilitation exercises on swallowing function and cerebral perfusion in dysphagic stroke patients.Methods Sixty-two stroke pa- tients with dysphagia were randomly divided into a treatment group(n=32)and a control group(n=30).The treat- ment group received electroacupunture,rehabilitation exercise and conventional medical treatment,while the control group received only rehabilitation exercise and conventional medical treatment.They were treated once a day,6 times a week for 4 weeks.Water drinking test,stethocatharsis scores and swallowing fluorography were used to assess the swallowing function before and after treatment.Single photon emission computed tomography(SPECT)was also em- ployed to observe the status of cerebral perfusion before and after treatment.Results It was shown that the swallo- wing function and cerebral perfusion in the treatment group were significantly better than the control group after treat- ment.The effective rate in the treatment group was 96.88% while that of the control group was 66.67%.Conclu- sion Electroacupuncture combined with rehabilitation exercises is effective in treating the dysphagic stroke patients, and can significantly improve the brain perfusion of these patients.

Objective The study aimed to investigate the best extraction process and the analgesia and anti-inflammatory properties of total flavonoids from Euphorbia prolifera. Methods Through single factor experiment and orthogonal test,factors that affect the extraction yield of total flavonoids were studied,including the extraction time,solid to liquid ratio, ethanol concentration and extraction times. The mice models of ear edema induced by xylene and twisting induced by acetic acid were used to evaluate the analgesia and anti-inflammatory effects of different extractions from Euphorbia prolifera. Results Total flavonoids were extracted by the refluxing method,and the optimum conditions were extracting for 3 hours,solid to liquid ratio of 1:30,ethanol content of 60% in the solvent,and processed for 2 times. The highest extraction yield of total flavonoids from Euphorbia prolifera was 5. 63%. The ethanol,ethyl acetate and n-butanol extracts decreased twisting and ear swelling in mice. Conclusion The extraction for total flavonoids from Euphorbia prolifera is simple,efficient and reproducible. The ethanol,ethyl acetate and n-butanol extracts of total flavonoids have obvious analgesia and anti-inflammatory effects.

Objective To evaluate the application of pooling HIV nucleic acid amplification testing (NAAT) among men who had sex with men (MSM) population, and to investigate suitable HIV screening strategy and the feasibility of calculation of HIV incidence using pooling NAAT among MSM population in China.Methods Four thousand eight hundred and fifty-six samples were collected from MSM population from April 2008 to September 2009 among with 4 156 were in Heilongjiang province and 700 were in Beijing in China. After standard testing with an HIV ELISA and WB confirmation testing, HIV antibody-negative samples were pooled and screened for HIV using NAAT.A three-stage pooling strategy was adopted.The HIV positive rate estimated by the four HIV screening strategies was calculated.In addition, 4 156 HIV positive specimens from Heilongjiang province were screened with the BED capture enzyme immunoassay (BED-CEIA).The HIV-1 incidences were estimated by BED-CEIA assay and pooling NAAT individually.ResultsOne hundred and forty-three of 4 856 subjects were HIV infected.130 were 3rd and 4th generation ELISA positive; 13 were antibody-negative but acutely HIV infected.According to the evaluation of four HIV screening strategies, routine HIV screening test together with pooling NAAT was more effective than other strategies for screening out window period generation ELISA+WB+pooling NAAT' were 2.68%(95% confidence interval CI=2.22%-3.14%), 2.82%(95%CI=2.35%-3.29%), 2.94%(95%CI=2.46%-3.42%) and 2.94%(95%CI=2.46%-3.42%), respectively.The differences were not significant (χ2=0.854 3, P=0.836 4).Of the 88 HIV positive samples from Heilongjiang province, 44 participants were tested as recent HIV infections by BED-CEIA assay. The estimated HIV-1 incidence was 2.36% (95%CI=1.63%-3.08%) and 2.92% (95%CI=1.01%-4.83%) based on BED-CEIA assay and pooling NAAT,respectively.Conclusions Pooling NAAT is a effective screening test in HIV negative population to detect window period infection among MSM population in China.

· AIM: To investigate the expression and the possible implication of CD40/CD40L costimulatory molecules in erythema nodosum of patients with Beh(c)et's disease.· METHODS: Sampling was done from erythema nodosum of 5 patients with Beh(c)et's disease and normal skin of 2 healthy individuals. Immunohistochemical staining was performed to examine the expression of CD4, CD8, CD19, CD68, HLA-DR,CD40 and CD40L molecules in the obtained tissues.· RESULTS: Approximately 90% of epidermic cells in erythema nodosum expressed CD40 molecule. In the dermis and subcutaneous tissue, a significantly increased number of CD4+Tcells, CD8+Tcells, CD19+cells, CD68+cells, HLA-DR+cells,CD40L+cells, and CD40+cells were observed in the erythema nodosum as compared with that in normal skin. Double staining showed that CD40L molecules were expressed on 45% of CD4+T cells. CD40 molecules were expressed on 100% CD68+ cells and 59.2% of HLA-DR+cells respectively.· CONCLUSION: A number of CD40/CD40L costimulatory molecules are upreguiated in the erythema nodosum of patients with Behcet's disease.

The single-chain antibody gene (ox26-scFv) to transferrin receptor (TfR) was synthesized and amplified by three-step PCR. After sequencing, the gene was cloned into prokaryotic expression vector pTIG-Trx which carried thioredoxin (Trx) gene and a C-terminal His.tag. The Ox26-scFv proteins achieved 31% yields of total bacteria proteins at 20 degrees C, after 0.02mM IPTG induction using the strain E. coli BL21 (DE3). The soluble scFv proteins in cytoplasm suspension were about 35% and the inclusion bodies were about 65%. The soluble products were purified by immobilized metal chelation affinity chromatography (Ni-NTA), a single band with molecular weight 29 kD appeared on SDS-PAGE gel. Rat GH3 cell immunocytochemistry staining showed that Ox26-scFv protein could recognize and bind to transferrin receptor. Injected SD rats with Ox26-scFv proteins by tail veins, the antibodies were detected from brain tissues specially on the brain capillaries 4 h later which indicate that Ox26-scFv proteins have a good target function to brain capillaries and can permeate the blood-brain barrier mediated by the transferrin receptors.
