Study on clinical effect and mechanism of Jianpi Qingre Huayu Recipe (健脾清热化瘀方) in treating patients with gastric ulcer

Objective： To study the effects of Jianpi Qingre Huayu Recipe （健脾清热化瘀方, JQH） in curing gastric ulcer and to preliminarily probe into its pathogenic mechanism, Methods： Fifty patients with gastric ulcer of Pi （脾）-insufficiency and stasis-heat syndrome type were assigned to the treated group （30 patients） and the control group （20 patients）. They were treated respectively with JQH and Ranitidine. At the same time, another group consisting of 20 healthy persons was set up for normal control. The clinical effect on gastroscopic figure and traditional Chinese medicine （TCM） syndrome were observed. Changes of T-cell subsets and interleukin-8 （IL-8） in serum as well as IL-8 in mucosa around the gastric ulcer were determined before and after treatment by flow cytometry and ELISA. Results： Comparison of the total effective rate on gastroscopic figure in the treated group and the control group （86.7% vs 80.0%） showed insignificant difference, but the cure rate and markedly effective rate in the former （50.0% and 20.0%） was higher than that in the latter （40.0% and 15.0%） respectively. Comparison of the total effective rate on TCM syndrome in the treated group and in the control group （96.7% vs 70.0%） showed insignificant difference, but the cure rate and markedly effective rate in the former （63.3% and 23.3%） was higher than that in the latter （50.0% and 20.0%） respectively. Serum levels of CD3^＋, CD4^＋, CD8^＋ got restored to normal range in the treated group after treatment but it was not so in the control group. IL-8 level in gastric mucosa was improved in both groups but the improvement in the treated group was better. Cenclusien： JQH could effectively treat gastric ulcer and partly reduce its recurrence through improving patients＇ immune function.

引经药独活根合二妙方可促进骨关节炎软骨损伤大鼠骨髓造血干细胞归巢

Objective:To investigate the effect of Ermiao Recipe(二妙方,EMR)with medicinal guide Angelicae Pubescentis Radix(APR)on the homing of bone marrow stem cells(BMSCs)to focal zone in osteoarthritis(OA)rats.Methods:Forty-eight Sprague-Dawley rats were randomly assigned to the sham-operated,model,EMR,and EMR plus APR groups(12 rats in each group).The OA rat model was induced by anterior cruciate ligament transection and medial meniscus resection.All rats were injected with recombinant human granulocyte colonystimulating factor[rhG-CSF,30μg/(kg-d)for continuous 7 days],and rats in the EMR and EMR plus APR groups were treated with EMR or EMR plus APR at 1.6 or 1.9 g/(kg·d)for 3 or 6 weeks,respectively.Cartilage histopathologic changes were observed by hematoxylin and eosin staining.Chondrocytes apoptosis and cartilage matrix components were tested by transferase-mediated deoxyuridine triphosphate-biotin nick end labeling assay and special staining,lnterleukin-1 B(IL-1β),tumor necrosis factorα(TNF-α),bone morphogenetic protein 2(BMP-2),and transforming growth factor beta-1(TGF-β_1)in serum were detected by enzyme-linked immunosorbent assay or radioimmunoassay assay.Matrix metalloproteinase(MMP)-13,tissue inhibitors of metalloproteinase(TIMP)-1,bromodeoxyuridine(BrdU),cluster of differentiation 34(CD34),and stromal cell derived factor 1(SDF-1)were measured by immunohistochemistry assay.Results:EMR and EMR plus APR significantly inhibited articular cartilage damage and synovium inflammation in OA rats at 3 or 6 weeks of treatment,the most obvious changes in these parameters were found in the EMR plus APR group.At 6 weeks,compared with EMR treatment,EMR plus APR remarkably inhibited chondrocytes apoptosis and the release of IL-1βand TNF-α,obviously decreased MMP-13 expression,and significantly increased expressions of proteoglycan,collagen,typeⅡcollagen and TIMP-1,serum levels of BMP-2 and TGF-β_1 as well as expressions of BrdU,CD34 and SDF-1 in cartilage articular(P0.01 or P0.05).Conclusion:The medicinal guide APR improved the therapeutic effects of EMR on OA rats by promoting directional homing of BMSCs to focal zone.
