ABSTRACT
Objective:To determine the content of ferric oxide in calamine powder. Methods:Flame atomic absorption spectrom-etry ( FAAS) was used to determine the content of ferric oxide. The determination results were compared with those of the titration method. Results:There was a good linear relationship between the absorbance and the concentration of iron within the range of 0. 5-4μg·ml-1 , the relative standard deviation of the repeatability test was 1. 2%, the average recoveries were 100. 4% and 99. 4%, the limit of quantitation and detection was 0. 081 μg·ml-1 and 0. 024 μg·ml-1 , respectively. Conclusion:The method of FAAS is ac-curate and quick with good specificity and high sensitivity, which can be used for the determination of ferric oxide in calamine powder.
ABSTRACT
Objective To establish a rat model at the same time in accordance with the “hot sheng syndrome” of traditional Chinese medicine and primary immune thrombocytopenic purpura of peripheral blood platelet reduction. Methods Using back multi-point injection of 20% dry yeast suspension on SD rats and 1∶4 dilution of rabbit anti SD rats platelet serum (APS) by intraperitoneal injection to establish a primary immune thrombocytopenic purpura “heat sheng”rat model.And observing rats of TCM syndrome characteristics, hemogram, myelogram and serotonin (5-HT) level of the temperature regulating center in thalamus.Results After injection of 2 h ~6 h temperature and daily water of the model group rats increased significantly,toe purper showed in fourth day of modeling and intestinal mucosal bleeding in thirty day of modeling(P <0.05);Platelet count in peripheral blood decreased significantly, bone marrow megakaryocyte number reduced significantly((P <0.05);5-HT level of the temperature regulating center of brain increased significantly((P <0.05).Conclusions The study of the primary immune thrombocytopenic purpura heat sheng rat model of combination of disease and syndrome reflected basically the pathological characteristics of purpura caused by “heat sheng” in primary immune thrombocytopenic purpura rat mode.
ABSTRACT
Objective To evaluate the clinical efficacy of integration of traditional Chinese and western medicine (ITWM) or pure western medicine on the patients with immune thrombocytopenia (ITP). Methods Randomized controlled trials (RCTs) on ITWM treatment of ITP were searched in PubMed, EMBASE, Wanfang database, CBMDisc, CNKI and VIP. Quality of the RCTs was evaluated strictly, and statistical analysis was performed with Cochrane Collaboration’s RevMan5.1.7 software. Results Twenty-two trials involving 1527 patients were included. The results of Meta-analysis showed that the ITWM treatment of ITP significantly improved the total effective rate [RR=1.23, 95%CI (1.17, 1.29), P<0.000 01] compared with that of pure western medicine treatment. Funnel plot showed that publication bias was small. Meanwhile, peripheral platelet count and the number of megakaryocyte which can generate platelet in bone marrow increased, obvious advantage was showed in long-term effect, and adverse reactions were reduced with ITWM treatment in ITP patients. Conclusion The existed limited evidences suggest that ITWM treatment of ITP can significantly improve clinical efficacy. The quantity and quality of research literature were limited, and well-designed randomized double-blind controlled trials with large sample and multi-centers are required for a more reliable conclusion.
ABSTRACT
ObjectiveTo examines the difference in illusion of transparency between high and low selfmonitoring individuals in different situations in reference to the experimental paradigm ofdrink recognition by Gilovich(1998 ).MethodsHigh and low self-monitoring individuals (the subjects) were selected by Snyder's Self-Monitoring Scale.Two situations were designed to study the illusion of transparency.One was acquaintance situation,and the other was the stranger situation.Results 1.The differences among the high and low selfmonitoring individuals had influence on the illusion of transparency.In low self-monitoring individuals there was a stronger illusion of transparency being demonstrated among both acquaintance situation (4.53 ± 2.12,2.53 ±2.45; t (16) =4.41,P＜0.05) and stranger situation (4.33 ±2.93,3.11 ±2.89; t (17) =2.11,P=0.05),while in high self-monitoring individuals,there were no illusion of transparency in either situations ( t (12) =0.38,P ＞ 0.05 ; t (22) =1.09,P＞ 0.05 ).2.The level of illusion of transparency in low self-monitoring group among acquaintance situation (2.00 ± 2.17) was higher than high self-monitoring group(0.23 ± 1.87 ),t (28) =2.40,P ＜0.05 ),while there was no difference between two groups in stranger situation (1.22 ±2.46,0.74 ±3.25,t (39) =0.52,P ＞0.05).ConclusinThe differences among the high and low self-monitoring individuals have inlluence on the illusion of transparency.The interactive situations have an influence on the level of illusion of transparency.
ABSTRACT
Objective: To study the effect of GLP-Ⅱ on residual bowel absorption of glucose in a rat model of short bowel syndrome. Methods: Rats undertaken 75% small bowel resection were randomly assigned to SB group and SB/GLP-Ⅱ group. Another group of weight-matched normal rats(Normal) received normal diet ad libitum was used as control group for SB group. All rats were allowed normal chow on the 1st postoperative day(POD). On the POD6,the intestinal glucose absorption data per unit length as well as per unit weight of ileum were measured by in vivo circulatory perfusion experiment. Results: Length of perfused ileum in 3 groups of rats were not significantly different. Wet weight to length ratio of perfused ileum in SB group was significantly higher than that of normal group,but significantly lower than that of SB/GLP-Ⅱ group. 45min glucose absorption of per cm ileum in SB/GLP-Ⅱ group was significantly higher than that of SB group(P0.05). Conclusions: In a rat model of SBS, GLP-Ⅱ can enhance the intestinal glucose absorption measured as per unit length of resudial ileum and GLP-Ⅱ manifests a trend to increase the glucose absorption measured as per unit wet weight of resudial ileum.
