Objective To observe and compare the clinical efifcacy of buyanghuanwu decotion combined with aspirin in treatment of aspirin resistance when transient ischemic attack(TIA). Methods 80 patients with TIA from September 2010 to October 2013 in Affiliated Hospital of Weifang Medical College were selected according to the standards and divided into two groups, with 40 cases in each group. Experimental group were orally administered with buyanghuanwu decotion and aspirin. Control group were orally administered with clopidogrel and aspirin. The levels of arachidonic acid (AA) and adenosine diphosphate (ADP) before therapy and in the 60 th and 90 th treatment day were detected by turbidimetry, respectively. Follow-up studies were performed to observe the recurrence numbers of TIA, cerebral infarction cases and adverse events, such as mucocutaneous hemorrhage and hemafacia in two groups during therapy. Results The levels of AA and ADP were decreased constantly with the therapy time in both two groups. The levels of ADP and AA in experimental group before therapy and in the 60 th and 90 th treatment day were not signiifcantly different from those in control group. No signiifcant differences of reoccurrence rate and the cerebral infarction rate were found between the two groups. However, there was statically signiifcant difference in the occurrence of adverse events between the two groups (P<0.05). Conclusion The clinical efifcacy of the combined treatment of buyanghuanwu decotion with aspirin shows no signiifcant difference with the combined treatment of clopidogrel and aspirin, but with lower incidence rate of adverse events.

Objective To study the expressions of cysteinyl aspartate specific proteinase 3 ( Caspase 3 ) and proliferating cell nuclear antigen ( PCNA ) in intestinal tissue of neonatal rats with necrotizing enterocolitis ( NEC ) , and the protective effect of glutamine ( Gln ) on NEC. MethodsThirty-six neonatal Sprague-Dawley ( SD) rats were randomly assigned into 3 groups at 48 h after birth (12 in each group). The control group were fed with milk replacer. The NEC group were fed with milk replacer and experiencing cold exposure after hypoxic-reoxygenation twice a day for 3 days, The Gln+NEC group were fed with milk replacer plus Gln and experiencing cold exposure after hypoxic-reoxygenation twice a day for 3 days. All the rats were sacrificed and intestinal tissues obtained at day 3 of the establishment of model. The histological changes of ileal tissues were studied using hematoxy lin-eosin ( HE ) staining. The expressions of Caspase 3 and PCNA were detected using immunohistochemical(IHC)method.Results Caspase3expressioninNECgroup(77.3±8.6)℅was significantly higher than the control group (18. 9 ± 3. 4)℅ and Gln+NEC group (50. 3 ± 6. 2)℅ ( P<0. 05). Also, Caspase 3 in Gln+NEC group was significantly higher than the control group (P<0. 05). PCNA expression in the NEC group ( 15. 0 ± 1. 9 )℅ was significantly lower than the control group (34. 2 ± 5. 8)℅ and the Gln +NEC group ( 24. 0 ± 3. 9 )℅ ( P <0. 05 ) . PCNA expression in the Gln+NEC group was significantly lower than the control group ( P<0. 05). The pathological score of the intestinal tissues was significantly correlated with Caspase 3 expression ( r = 0. 769, P = 0. 005 ), Caspase3/PCNA ratio (r=0. 835,P=0. 002) and PCNA expression (r= -0. 698, P=0. 014) in the NECgroup.Conclusions Up regulation of Cas pase3 and down regulation of PCNA might be correlated with the process of NEC. Gln might be effective in prevention and healing of NEC by inhibiting apoptosis and promoting cell proliferation.

Objective To investigate the factors affecting the stability of the volatile oil extracted fromYinqiaosan Decoction.Methods The main chemical compositions and the extraction repetitiveness of the compound volatile oil were determined by GC-MS, and the stability of multiple extracted volatile oil was studied. Absorbance of the compound volatile oil was used as the evaluation index, and the factors affecting the stability of the of the compound volatile oil were investigated, such as illumination, temperatures and pH values of volatile oil solution and metal ions.Results The results of the GC-MS chromatograph indicated that the main chemical compositions of the compound volatile oil extracted fromYinqiaosan Decoction twice were the same. The results of the stability of the volatile oil showed that the preservation temperature and illumination affected the stability of the volatile oil to a certain extent. The absorbance values of the compound volatile oil changed slowly when it was stored at a relatively low temperature (4℃) and shielded from light, and it was less stable when stored in normal temperature and under illumination. Meanwhile, the absorbance of the compound volatile oil changed quickly in acid or alkaline solutions and was in instability. The metal ions, such as Cu2+ and Fe3+, have chemical reactions with the compositions of the compound volatile oil and there was a big change in the UV-Vis spectrum of the compound volatile oils.Conclusion The compound volatile oil should be stored at a relatively low temperature (4℃) and shielded from light. At the same time, it should be stored avoiding acids, alkaline and the metal ions, such as Cu2+ and Fe3+, to guarantee its stability. This study provides a reference for the preservation conditions and the preparation conditions of the compound volatile oil extracted fromYinqiaosan Decoction.

Objective To investigate the implications of ratio of the CD4+ and CD25+ positive regulatory T cells (CD4+CD25+Tregs) in peripheral blood mononuclear cells (PBMC) and its associated regulatory factors such as forkhead transcription factor 3 (Foxp3) mRNA transcriptional activity in PBMC,serum levels of transforming growth factor beta-1 (TGF-β1),and interleukin 10 (IL-10) in the immunopathology of patients with middle to late staged nasopharyngeal carcinoma (NPC) based on a clinical trial.Methods In this study,18 NPC cases at middle to late stage as observing group and 10 healthy persons as control group were included to detect their ratio of the CD4+CD25+Tregs in the PBMC with flow cytometry (FCM) technique,transcriptional activity of Foxp3 with RT-PCR procedure,and serum levels of TGF-β1 and IL-10 with enzyme-linked immunosorbent assay (ELISA) method.A comparative analysis was used to explore their implications in the immunopathological correlation of NPC cases with their lesion.Results The ratio of the CD4+CD25+Tregs to total CD4+T cells in PBMC was significantly increased [(4.23 ±0.53)％ vs (2.65 ±0.31)％,t =8.60,P ＜0.01],accompanied with significantly elevated levels of Foxp3 transcription in PBMC (3.699 ± 0.309 vs 1.109 ± 0.146,t' =31.08,P ＜ 0.05],and serum contents of TGF-β1 [(645.56 ± 39.61) pg/ml vs (488.82 ± 36.91) pg/ml,t =10.27,P ＜ 0.01] and IL-10 [(1.27 ± 0.21) pg/ml vs (0.68 ± 0.08) pg/ml,t' =10.61,P ＜ 0.05] in these patients,when compared with that of healthy controls.Conclusions It may be true that CD4 + CD25 + Tregs,transcriptional regulatory factor Foxp3,and cytokines TGF-β1 as well as IL-10 altogether were composed of a regulating system in a positive feedback way to promote the developing process of immunotolerance phenomena in the tumor microenvironment and the initiation of immunoescape among patients with middle to late staged nasopharyngeal carcinoma.
