Objective: By means of serum pharmacochemistry combined with modern chromatographic technology to elucidate the material basis for efficacy of aqueous extract from Gardenia jasminoides (AEGJ), which has antipyretic activities with bitter-cold property. Methods: Waters 2695 HPLC was employed as the detection system, based on the same chromatographic eluted condition, physiological and DNP-induced fever syndrome serum samples, collected from hepatic portal vein of rats after ig administration of AEGJ, were under determining to compare the absorptive variation of the chemical compounds. Results: The chromatographic fingerprints of common peaks for six batches of AEGJ were established to ascertain the optimized administration dosage, blood collection time, and the method used to process the serum. Compared with the normal administrated group under physiological status of rats, we found that the significant increment absorption of jasminoidin and the generation of two new migration compounds in the DNP fever syndrom model group. Conclusion: The increment absorption and the migration of chemical compounds in serum of DNP fever syndrome pathological model of rats might reasonably lead us to consider these chemical compounds as symbols of the bitter-cold property of G jasminoides.

OBJECTIVETo analyzed the relationship between lumbar endplate Modic area changes rate and low back pain by measuring MRI T2 sagittal image of lumbar endplate Modic area changes rate.

METHODSFrom December 2011 to June 2012,70 patients with low back pain in operation were evaluated on pain by VAS and function by JOA,and examined by MRI including 39 males and 31 females with an average age of (51.00 +/- 11.89) years ranging from 29 to 72 years old. Among them, 54 cases had lumbar endplate Modic changes involving 15 cases in types Modic I ,21 cases in type Modic II, 11 cases in type Modic III ,mixed type Modic in 7 cases (eliminated for too few cases). Modic area changes and corresponding vertebral area were measured on MRI T2 median sagittal. The areas of two ways were compared to yield the rate of changes for Modic, for multisegmental Modic changes to calculate the total ratios. A correlation was observed among JOA, VAS and the rate of Modic changes.

RESULTSThe correlation coefficient of change rate of Modic I with JOA score was r = -0.308, P = 0.048 < 0.05, there was a negative correlation;the correlation coefficient of change rate of Modic I with VAS scores was r = 0.428,P = 0.021 < 0.05, there was a positive correlation. The correlation coefficient of change rate of Modic II with JOA score was r = -0.375, P = 0.043 < 0.05, there was a negative correlation;the correlation coefficient of change rate of Modic II with VAS score was r = 0.352, P = 0.041 < 0.05, there was a positive correlation. The area change rate of Modic III had no significant correlation with low back pain degree (P > 0.05).

CONCLUSIONModic I and II area changes rate of of patients with low back pain is closely related to the degree of pain low back pain, Modic III area changes rate is not significant correlated to the degree of lower back pain.

Objective: To study the effect of recombinant human intestinal trefoil factor ( rhITF) on the healing of rat chronic gastric ulcer , protect gastric mucosal and mechanisms are involved. Methods: (1) Acute gastric mucosal injury was induced by ethanol, stress, aspirin and pylorusl ligation. The injury index ,MDA, GMBL,hexosamine (Hex) and acid output were measure. (2) Chronic gastric ulcer was induced in rats by application of 50% glacial acetic acid to the serosa of the glandular stomach. After injury, rats received by rhITF or vehicle orally twice daily for 11 days. On day 12, gastric mucosal blood flow(GMBF)was measured under ether anesthesia. Then the pylorus was ligated for 3 hours and each stomach removed. The gastric acid output, ulcer index, Hex and nitric oxide(NO) content in gastric mucosa, as well as iNOSmRNA in the ulcer bed were determined. Results: (1) rhITF protected gastric mucosa from the acute lesion, and increased Hex content in gastric mucosa. (2) rhITF treatment significantly decreased the ulcer index and gastric acid output, but increased the GMBF, Hex and NO content in comparison with the control groups. In addition, rhITF also stimulated iNOSmRNA expression in the ulcer bed by situ hybridization analysis. Conclusion: rhITF can protect gastric mucosa against acute lesion, and enhance the healing of chronic gastric ulcer in the rats.This action may result from the inhibition of gastric acid output, increase of GMBF.Hex and NO content and rhITF stimulated iNOSmRNA expression.

OBJECTIVETo evaluate the impacts on the short-term efficacy and the long-term prevention of recurrence of allergic rhinitis treated with the triple-strong stimulation at Dazhui (GV 14) so as to provide the convenient and long-term effective therapy of acupuncture and moxibustion for allergic rhinitis.

METHODSOne hundred and twenty cases of allergic rhinitis were randomized into an acupuncture group, an acupuncture + medication group and a triple-strong stimulation group, 40 cases in each one. In the acupuncture group, acupuncture was applied at Dazhui (GV 14), Fengchi (GB 20), Baihui (GV 20), Yintang (GV 29) and the others, stimulating with reinforcing manipulation for the deficiency and reducing manipulation for the excess, once every day. In the acupuncture + medication group, on the basis of acupuncture therapy, claritin (loratadine tablets) was supplemented for oral administration, 10 mg, once every two days, continuously for 30 days. In the triple-strong stimulation group, on the basis of acupuncture therapy, the strong needling, strong cupping and strong moxibustion were applied at Dazhui (GV 14). This combined therapy was given once every day in the first 3 days and once every two days afterwards. The 10 day treatment made one session, at the interval of 3 days between the sessions and totally 3 sessions were required in the three groups. Separately, before treatment, after treatment and in 6 months after treatment, the changes of symptom and physical sign score and value of single item symptom including nasal itching, nasal blockage, sneezing and rhinorrhea were observed in the patients of the three groups. And the long-term clinical efficacy was compared among the three groups.

RESULTSThe symptom and physical sign score and the value of single item symptom were all reduced in the three groups after treatment and in 6 months after treatment (P < 0.001, P < 0.01, P < 0.05). The results in the triple-strong stimulation group were superior to the other two groups (all P < 0.05). In the triple-strong stimulation group, the total effective rate was 92.5% (36/40) in the follow-up of 6 months after treatment, which was better than 60.5% (23/38) in the acupuncture group and 69.2% (27/39) in the acupuncture + medication group (both P < 0.01).

CONCLUSIONThe combined therapy of acupuncture and the triple-strong stimulation at Dazhui (GV 14) achieves the reliable and effective result in the clinical treatment of allergic rhinitis and displays the good role on the prevention from long-term recurrence.

AIM:To screen the gene expression profiles of normal gastric mucosa,primary gastric cancer and metastatic lymph nodes by gene expression microarray and the associated genes with lymph node metastasis by bioinformatics. METHODS:The differentially expressed genes of nontumorous gastric mucosa (group A),primary gastric cancer (group B) and metastatic lymph nodes (group C) were screened by gene expression microarray obtained from Affymetrix company. The results were further analyzed by bioinformatic software including Gene Expression Profiles Analysis of Cohort Experiment,Gene Ontology Enrichment Analysis and Pathway Significant Analysis. The expression of TLN1 in group A,B and C were confirmed by real-time reverse transcription PCR. RESULTS:278 genes were persistent up-regulated in group A,B,C,which participated mainly in immunologic responses,cell adhesion,phosphate transport,inorganic anion transport,cell chemotaxis,cell motility and signal transduction. While 387 genes were persistent down-regulated in group A,B,C,which were concerned with digestion,glucide metabolism,lipid metabolism,protein metabolism,one-carbon compound metabolism,nitrogen compound catabolism and cell adhesion. The pathway analysis suggested that integrin-mediated cell adhesion pathway were abnormally regulated. These genes including THBS1,TLN,CAPN3,ITGAX,SORBS1,CAPN6,CAPN9 were continuous up-regulated or down-regulated in integrin-mediated cell adhesion pathway. The expressions of TLN1 in group A,B,C were 0.0000342?0.0000711,0.1064?0.1251 and 0.2886?0.3529,respectively. The expression of TLN1 in metastatic lymph nodes was significantly higher than that in nontumorous gastric mucosa and primary gastric cancer (P
