Objective:To locate the region of antigenic epitopes recognized by monoclonal antibody(Z8) against human tumor necrosis factor ?(hTNF ?).Methods:Several recombinant fusion expression vectors were constructed which contained hTNF ? mutant genes deleted different parts respectively. After induction with IPTG, the fusion proteins were expressed and analyzed by SDS PAGE and Western blot.Results:Z8 specially recognized the fusion products which contained amino acids from 92 to 157 of hTNF ?, but not GST and its fusion protein with amino acids from 1 to 91 of hTNF ?.Conclusion:The antigenic epitopes recognized by Z8 were located in the sequence region 92 157 of hTNF ?.

The effects of selenium-enriched yeast (Sey) on DTH in immunosuppressive mice have been investigated. It was found that Sey (30, 60, 90 mg?kg-l?d-1?6 d, ig) was able to antagonize lowered DTH by cyclophospha-mide (Cy); Meanwhile, the thymus and spleen weights were increased by Sey (30, or 60 mg?kg-1?d-1) in immunosuppressive mice. Sey also potentiated the lowered ConA and LPS-indu-ced proliferation of splenocytes in DTH mice at the doses of 30, 60, or 90 mg ?kg-1 and 60 or 90 mg?kg-1 respectively. These results suggested that Sey could enhance the functions of lymphocytes.

Animal models of rheumatoid arthritis(RA)especially adjuvant arthritis(AA)in rats and collagen induced arthritis(CIA)in mice have much character similar to human RA in pathological mechanism,clinical representation and so on. The models are more ideal in investigating RA and selecting drugs of anti inflammation and immunity. To discuss the pathological mechanism and the relation between animal models of RA and clinic will be important not only to research RA in pathology,physiology,nervous endocrine immunity and so on,but also to find out safety and effective drugs of treatment RA. The articl summarizes several animal models of RA in establishment,pathological and clinical changes,inflammatory immune regulation and so on.

Objective　To investigate the effect of positive pressure ventilation on radiosensitivity of the patients suffering from primary lung cancer. Methods　Thirty cases of lung cancer were randomly divided into two groups: ① combining therapy group: patients treated with posi tive pressure ventilation using BiPAP respirator and radiotherapy;② simple radi otherapy group. The changes of PaO2, SaO2, blood white cells and the cellula r immunological function were observed before and after treatment. Resul ts　Nasal or naso-facial positive pressure ventilation with BiPAP respi rator increased PaO2 significantly with the maximum of 7.5 kPa, SaO2 was ma inteined at above 95%. No significant change for the cellular immunological func tion was found in the combining therapy group （P>0.05）and only one patient with leukopenia（6.7%）. But in the radiotherapy group, the lymphocyte transfor mation efficiency and the ratio of CD4/CD8 were obviously decreased（P<0 .01), and leukopenia was found in 5 cases（33.3%）. Conclusion　 Nasal or naso-facial positive pressure ventilation with BiPAP respirator could improve the effect of radiotherapy for lung cancers. It could also increase PaO 2 significantly and has protective rote to the marrow and cellular immunologic al function of the patients.

ObjectiveTo summarize point Shenmai(BL62)indications and the characteristics of acupuncture and moxibustion by sorting out literature on point Shenmaiin ancient literature.MethodShenmai, Yangqiao and Guilu were used as search words to search Chinese Medical Classics to sift out items on indications for point Shenmai and its combination and the characteristics of point combination and acupuncture and moxibustion and establish the relevant database. Statistical analysis was made using the SPSS19.0 software.ResultTwo hundred and eighty-seven items on point Shenmai and 274 items on the indications met the inclusion criteria. There were 47 indications for the single acupoint and 19 kinds of diseases on which the single acupoint had a marked therapeutic effect. Lumbago, ophthalmalgia, vertigo, headache and mania were ranked in the top five. There were 64 indications for its combination and 22 kinds of diseases on which its combination had a marked therapeutic effect. Epilepsy, Lumbago, stroke, podalgia and headache were ranked in the top five. The commonly used depth of needle insertion was 3 fen, acupuncture time was 6-7 respiratory cycles and stimulation intensity of moxibustion was 3 moxa cones.ConclusionSingle point Shenmai and its combination are both good at treating internal medicaldiseases and especially meridian diseases in the limb. Acupuncture and moxibustion are the commonly used methods.

Objective To explore the drug resistance diversity of pseufomonsd aeruginosa.Methods We did sensitivity experiments by 23 antibiotic of 1731 pseudomonad aeruginosa identified from clinic during 1997 to 2008,Results In 1 731 pseudomonad aeruginosa,the samples were main from phlegm,accounted for 58.5%.the second from secretion accounted for 24.7%.The drug resistance of pseudomonad aeruginosa for ampicillin、cefazolin and cefuroxime sodium were all higher than 90%,the second were trimethoprim/sulfamethoxazole 83.2%.The antibacterial medicines of drug resistance higher than 70%were netilmicn(75.2%)、ofloxacin(70.4%)、tetracycline(74.1%)、choramphenicol(72.0%).The antibacterial medicines of drug resistance Iower than 30%were Cefoperazone/Sulbactam、cefepime、imipenem、ceftazidme.In 12 years,the drug resistance diversity had enhanced prevalent trend.The enhanced speed of proportion drug was slow in 2004～2007,but it was fast again in 08 year.Conclusion The pseudomonad aeruginosa have become one of the most clinical routine nosogenetic germs.It showed single and anti muhiresistance of antibioties seriously.In order to improve antibacterial treating effect,we should inspect the drug resistance continuously in our area.We could select rationally antibacterial medicine according to the result of medicine sensitivity experiments.

Objective To evaluate the clinical application of contrast-enhanced digital subtraction MRI in musculoskeletal malignant tumors.Methods Fifty patients with musculoskeletal malignant tumors were scanned by contrast enhanced T 1WI with an injection of Gd-DTPA (0.1 mmol/kg), and digital subtraction was performed between post-contrast-enhanced images and pre-contrast-enhanced images. Musculoskeletal malignant tumors were evaluated by means of a contrast-to-noise ratio (C/Ns). Imaging sign of the musculoskeletal malignant tumors were compared between subtraction MR images and conventional contrast enhanced MR images.Results Contrast-enhanced digital subtraction MR images were better than conventional contrast enhanced MR images. All cases were confirmed by operation or pathology. All the lesions had higher C/Ns on subtraction MR imaging than on conventional contrast enhanced MR images. C/Ns was 109.74?5.10 (?s) for subtraction MR imaging and 23.61?3.16 for conventional contrast enhanced MR images (t=101.51, P

Object To study the feasibility of flocculation procedure on Bushenhuoxue Decoction, using chitosan instead of alcohol. Methods Using chitosan clarifier to the flocculation procedure of Bushenhuoxue Decoction; selecting the optimum content of chitosan and the density of decoction according to the total extract, and the content of icariin, comparing with the flocculation procedure by alcohol sedimentation. Results Chitosan clarifier could make the decoction clarify as alcohol does. On the retaining of active compounds, the former was better than the later. Conclusion Chitosan can be used to the flocculation procedure of Bushenhuoxue Decoction instead of alcohol.
