Objective:To observe effect of Xiaoyu Zhixue Tablets on expression of platelet membrane glucoprotein in the patient of hemorrhagic thrombopathy and probe into the mechanism of the therapy.Methods:148 cases of hemorrhagic thrombopathy were randomly divided into a Chinese drug group(n=98)treated by Xiaoyu Zhixue Tablets,and a Western medicine group(n=50) treated by adrenosem,vitamine C,K,P.They were treated for 6 months.After treatment the therapeutic effect of hemostasis and the recovery rate of platelet aggregation in the two group were observed and analyzed.Before and after treatment expressions of platelet membrane glucoproteins GP Ⅰ b/Ⅸ,GP Ⅱ b/Ⅲa,GP Ⅰ b,GP Ⅱ b,GP Ⅲ a and p-selectin expression were detected with flow cytometry in the two groups and in 34 healthy persons(normal group).Results:The total effecive rate of hemostasis was 89. 8% in the Chinese drug group and 54.0% in the Western medicine group,and the recovery rate of platelet aggegation was 72.4% in the Chinese drug group and 4.0% in the Western medicine group,with significant differences(both P0.05).Conclusion:Xiaoyu Zhixue Tablets can up-regulate platelet membrane glucoproteins GP Ⅰ b/Ⅸ,GP Ⅱ b/Ⅲ a,GP Ⅰ b,GP Ⅲ a and p-selectin expression,which is possibly one of the mechanisms for treatment of hemorrhagic thrombopathy.

OBJECTIVETo develop and evaluate the short version of patient reported outcomes (PROs) questionnaire for gastric stuffiness (Wei Pi) patients with modern test theory and technologies, hoping to provide testing tools for related clinical practice and scientific researches with higher quality and less administrative and response burdens.

METHODSUsing descriptive study design, clinical data were collected with sociological questionnaire and previous developed full items version of PROs instrument for gastric stuffiness (Wei Pi) patients via field and online surveys between Sep 2011 and Mar 2012. The statistical analysis group identified the termination parameters firstly, and then selected items with discrimination, fitting residual, item information curve (IIC) , item characteristic curve (ICC), and the rank of computerized adaptive testing (CAT) select proportion, etc. After assumption evaluation of item response theory (IRT), IIC, ICC, difficulty coefficient distribution, items-response relation and thresholds, etc. were used for psychometric evaluation of instrument.

RESULTSA total of 331 patients [Ages: 31.99 +/- 10.29 yrs; Male: 186 (56.3%)] were enrolled in statistical analysis. The test termination criterion was Max SE = 0.2 or Max items number =16. After items selection, a 15-item short version of instrument, which contains symptoms facet (8 items) and impact facet (7 items) was generated. With good unidimensionality, local independence, and monotonicity, the IC and ICC in IRT analysis showed good working capability of the questionnaire. The difficulty coefficient distribution and items-response relation were also rational, as well as response thresholds.

CONCLUSIONSThe short version of PROs instrument for adult gastric stuffiness (Wei Pi) patients was successfully developed and assessed. The instrument with good methodological and reporting quality could be used in clinical and scientific evaluating their symptoms and impact.

AIM To investigate the effect of recipient kidney function by CsA coadministration Ber used to induce immune tolerance in rats of allogenic cardiac transplantation. METHODS The authors established the SD to Wistar rats heterotopic cardiac transplantation model by Onos methods.Observe the cardiac allograft survival and levels of BUN and Cr in the recipients plasma. The recipients were classified into 5 groups randomly after heterotopic cardiac transplantation were performed. Group A (Wistar to Wistar)): Received placebo intraperitoneal injected for 21 days; Group B (SD to Wistar): Saline intraperitoneal injected for 21 days; Group C (SD to Wistar):CsA 2 mg?kg -1 ?d -1 intraperitoneal injected for 21 days; Group D(SD to Wistar):Ber 16 mg?kg -1 ?d -1 gastrointubation for 21 days; Group E(SD to Wistar): Ber 16 mg?kg -1 ?d -1 gastrointubation coadministration CsA 2 mg?kg -1 ?d -1 ip for 21 days. RESULTS The levels of BUN and Cr in recipint plasma is lower evidently compare with the group with CsA ip simply. CONCLUSION Ber can reduce the renal toxicity in recipients by CsA which was intraperitoneal injected (ip) over a long period time.

AIMTo study the chemical composition of Tripterygirm wilfordii Hook. f.

METHODSColunm chromatography was used to separate the chemical constituents. UV, IR, MS, HRMS, 1HNMR, 13CNMR (COM and OFR), 1H-1H COSY, 1H-13C COSY, NOESY and COLOC spectra were used to determine the structures of the isolated constituents.

RESULTSTwo sesquiterpene alkaloids were isolated and their structures were elucidated as wilforgine and wilfordlongine on the basis of spectral evidence.

CONCLUSIONWilfordclonine is a new sesquiterpene alkaloid.

Objective To evaluate the efficacy and safety of 0.03% tacrolimus ointment for the treatment of atopic dermatitis (AD) in Chinese children. Methods A total of 139 children, 2 to17 years of age, with moderate to severe AD from 5 study centres were enrolled in this multicentre, randomized, double-blind, vehicle-controlled, parallel group study. Treatment with 0.03% tacrolimus ointment or vehicle was applied twice daily to the affected areas for 3 weeks. Visits were scheduled on day 1 (base line, before treatment) and 1, 2, 3 weeks after the treatment. The main therapeutic parameter was the efficacy rate at the end of the treatment. Results The efficacy rates were 84.6% and 29.0% for tacrolimus group and vehicle group, respectively (P

Increasing evidence suggests that cancer stem cells (CSCs) are responsible for tumor initiation and maintenance. Additionally, it is becoming apparent that cyclooxygenase (COX) signaling is associated with canine mammary tumor development. The goals of the present study were to investigate COX-2 expression patterns and their effect on CSC-mediated tumor initiation in primary canine mammary tissues and tumorsphere models using immunohistochemistry. Patterns of COX-2, CD44, octamer-binding transcription factor (Oct)-3/4, and epidermal growth factor receptor (EGFR) expression were examined in malignant mammary tumor (MMT) samples and analyzed in terms of clinicopathological characteristics. COX-2 and Oct-3/4 expression was higher in MMTs compared to other histological samples with heterogeneous patterns. In MMTs, COX-2 expression correlated with tumor malignancy features. Significant associations between COX-2, CD44, and EGFR were observed in low-differentiated MMTs. Comparative analysis showed that the levels of COX-2, CD44, and Oct-3/4 expression varied significantly among TSs of three histological grades. Enhanced COX-2 staining was consistently observed in TSs. Similar levels of staining intensity were found for CD44 and Oct-3/4, but EGFR expression was weak. Our findings indicate the potential role of COX-2 in CSC-mediated tumor initiation, and suggest that COX-2 inhibition may help treat canine mammary tumors by targeting CSCs.

OBJECTIVETo investigate the correlation of Epstein-Barr virus (EBV) infection and childhood lymphoma.

METHODSParaffin-embedded specimens of lymphoma collected between 1996 and 2005, including 36 Hodgkin lymphomas (HL) and 51 non-Hodgkin lymphomas (NHL), were included in this study. Paraffin-embedded specimens of reactive hyperplasia of lymph nodes (RL) collected during the same period were used as controls. Immunohistochemical (IHC) assay was used to detect EBV-LMP1 and in situ hybridization (ISH) to detect EBV-EBERs.

RESULTSEBV was detected in 72.2% (26/36) of the Hodgkin lymphomas, 15.7% (8/51) of the non-Hodgkin lymphomas and 33.3% (15/45) of the reactive hyperplasia of lymph nodes. There was a significant difference among Hodgkin lymphoma, non-Hodgkin lymphoma and RL (P = 0. 000).

CONCLUSIONChildhood Hodgkin lymphoma is closely correlated with Epstein-Barr virus infection. However, the low rate of EBV infection detected in childhood non-Hodgkin lymphoma might be due to heterogeneous distribution of pathological types in this study.
