Objective:To investigate the immunogenicity of SARS-CoV N DNA vaccine and the feasibility of live-attenuated Salmonella typhimurium as the carrier to deliver the N DNA vaccine.Method:The recombinant attenuated salmonella strain CS022 harboring the pcDNA-N DNA vaccine was constructed.And mouse was immunized with the recombinant strain via intranasal and oral routes.Cellular and humoral immune responses were assessed by ELISA,lymphocyte proliferation assays,ELISPOT and FACS.Result:The oral immunization with the transformed salmonellae elicited strong immune responses mainly including high level of N-specific antibody,a dramatic activation of IFN-?-secreting cells,a high level of lymphocyte proliferation,and a high level of activated CD8+ T cells.Conclusion:Live-attenuated Salmonella typhimurium could effectively deliver the SARS-CoV N DNA vaccine in vivo.These encouraging pre-clinical data provide a rational basis for undertaking a new immune style to investigate SARS vaccine.

OBJECTIVE: To study the effects of electroacupuncture and diet adjusting on insulin resistance in rats with nutrition obesity, and the role of electroacupuncture and diet adjusting in the treatment of obesity. METHODS: Obesity was induced in rats by high-fat diet. Rats with nutrition obesity were randomly divided into high-fat diet (HD) group, high-fat diet plus electroacupuncture (HA) group, normal diet (ND) group and normal diet plus electroacupuncture (NA) group, with another group of SD rats as normal control (NC). After 15 days, all the rats' body weight and length were measured, the Lee's index was calculated, and the levels of total cholesterol (TC), triglycerides (TG), free fatty acid (FFA), fasting plasma glucose (FPG), fasting insulin (FINS) and tumor necrosis factor-alpha (TNF-alpha) were detected. RESULTS: Compared with the HD group, food intake, body weight and viscera fat weight of the rats with nutrition obesity in the HA group and the NA group were markedly reduced (P<0.05). The levels of blood serum TC, FFA and IR index in the NA group were obviously lower than those in the HD group (P<0.01). The levels of TNF-alpha and FINS in the NA group were lower than those in the HD group (P<0.05). CONCLUSION: Electroacupuncture plus diet adjusting can decrease the levels of serum TNF-alpha and FINS of the obesity rats, and improve the state of insulin resistance.

OBJECTIVETo explore the differences of electroacupuncture (EA) on onset time and symptom improvement for treatment of different types of functional constipation.

METHODSThirty-eight cases of constipation were selected, including 9 cases of constipation-predominant irritable bowel syndrome (IBS-C), 10 cases of slow transit constipation (STC), 10 cases of pelvic floor dyssynergia (PFD) and 9 cases of inadequate defecatory propulsion (IDP). The electroacupuncture was applied at Tianshu (ST 25), Fujie (SP 14), Shenshu (BL 23), Dachangshu (BL 25) and so on in abdominal and lumbosacral area, 5 times per week, 10 times as a treatment course. The onset time, score of clinical symptoms of constipation and improvement of every symptom in each group were compared.

RESULTS(1) The onset time was (1.78 +/- 0.83) days in IBS-C type, (3.11 +/- 1.90) days in IDP type, (4.10 +/- 1.85) days in STC type and (4.30 +/- 2.00) days in PFD type, indicating statistical differences between IBS-C type and STC type, IBS-C type and PFD type (both P < 0.05). (2) Compared before the treatment, the total scores of symptoms on the onset day in each group were all improved (P < 0.05, P < 0.01), and score of IBS-C type was superior to the rest 3 types (P < 0.05, P < 0.01). (3) EA improved desire to defecate or frequency of defecation in each type (P < 0.05, P < 0.01), in which both were improved in STC type and PFD type, and the improvement of defecation frequency was more significant in STC type (P < 0.01). EA relieved unsmooth defecation or pendant-expansion feeling in each type (all P < 0.05), in which both were improved in IBS-C type (both P < 0.05). EA relieved abdominal distension and pain in IBS-C type, STC type and PFD type (all P < 0.05), while its effects were not obvious on defecation difficulty, defecation time and defecation texture (all P > 0.05).

CONCLUSIONThe electroacupuncture for treatment of 4 types of constipation is characterized by rapid onset; the improved symptoms are not identical in the electroacupuncture treatment plan for each type of defecation; the main improvement of symptoms are lied on desire to defecate and frequency of defecation, unsmooth defecation or pendant-expansion feeling and abdominal distension and pain. Meanwhile the improvements of defecation texture, defecation difficulty and defecation time were not signi-ficant.

OBJECTIVE: To explore the change rules of peak area ratio of STR loci to Amelogenin (AMEL) locus (STR/AMEL), a sex-determining gene in DNA degradation, and to evaluate the application of STR/AMEL value in the estimation of DNA degradation degree. METHODS: DNA was extracted from iliopsoas, and the variations of STR/AMEL value (Penta E/AMEL, Penta D/AMEL, FGA/AMEL) were analyzed after the artificial degradation was made by DNase I, and the changes of these three ratios of the iliopsoas naturally degraded in an outdoor environment were also analyzed. The regression curves were analyzed using the periods of DNA degradation and outside the body as the independent variable (x) and the STR/AMEL value as the dependent variable (y) and three curve equations under two conditions were established. RESULTS: Both under the conditions of artificial and natural degradation, STR/AMEL value had a negative relationship with the degradation time. The relationship between STR/AMEL and degradation time can be well simulated by the cubic function. R2 was over 0.99 under controlled degradation condition and over 0.86 under natural degradation condition. CONCLUSION The STR/AMEL value (Penta E/AMEL, Penta D/AMEL, FGA/AMEL) is negatively related with the DNA degradation degree, which follows mathematical regression models strictly, and it might be applied to evaluate the DNA degradation degree.

L9 (3(4)) orthogonal experiment was used to design the extraction technology of compound Clematidis Radix spray. Weight coefficients of active ingredients and dry extract rate were solved by information entropy. Support vector machine (SVM) was established and the model parameters were optimized through the genetic algorithm. Grid search algorithm was used for optimization of extraction technology of Clematidis Radix spray. The optimal extraction technology was to extract Clematidis Radix spray in water with 6 times the weight of herbal medicine for 3 times, with 2 h once. Bias of value between real and predicted by SVM was 1.23%. SVM was compared with traditional intuitive analysis of orthogonal design. It indicates that the new method used to optimize the extraction parameters of compound Clematidis Radix spray is more accurate and reliable.
