不同加工方法对贯叶连翘中黄酮类成分的影响

目的:研究不同加工方法对贯叶连翘中5种主要黄酮类成分的影响及变化规律,以寻找适宜的干燥方法和条件。方法:贯叶连翘全草洗净泥土,分别经4、-20、-80℃储存48 h后阴干,直接阴干和晒干方法进行加工后,剪切后得到5组样本。采用超高液相色谱(UPLC-PDA)测定贯叶连翘中5种主要的黄酮类成分含量。将5种不同加工方法处理样品的数据标准化处理,以主成分分析法(PCA)综合评价贯叶连翘经不同加工方法处理后其中的黄酮类成分的含量变化规律,并对不同加工方法进行多元比较。结果:经UPLC分析,贯叶连翘5种黄酮类化合物均可在10 min内出峰,且在各自的线性范围内线性关系良好(r0.999 1),检出限范围为0.020~0.107μg·mL~(-1),定量限范围为0.133~0.667μg·m L-1,平均加样回收率为95.05%~102.47%,相对标准偏差(RSD)值为0.13%~1.99%。PCA结果显示,不同处理方法对贯叶连翘成分含量影响综合评分依次为:晒干-80℃-20℃阴干4℃。结论:建立的UPLC方法快捷、灵敏、准确,适用于5种主要黄酮类成分的同时测定。PCA结果说明,不同加工方法对贯叶连翘中黄酮类活性成分有一定影响,综合主要成分的变化规律,选择-20℃冷冻48 h后晾干作为优化的加工方法。     

在中西医结合的道路上砥砺前行

正记得2008年健康报刊登了我撰写的《在扬弃中发展中医》一文,顿时网上的评论铺天盖地,可谓一石激起千层浪,褒贬不一。抨击"作者不懂中医,只会攻击中医"的有之;力挺"发展中医必须与时俱进"的也有之。我压力极大,夜不能寐。好在荣获当年健康报"头条新闻大奖赛"一等奖,得到了些许安慰。我始终相信任何事物都不可能脱离时代和社会环境而超然存在,社会和自然发展规律就是物竞天择,适者生存。中     

直肠癌Dixon术后吻合口漏相关危险因素分析

目的分析低位直肠癌Dixon术吻合口漏的相关危险因素。方法回顾性分析我院2013年6月~2019年6月行低位直肠癌根治术的179例患者的临床资料,对术后发生吻合口漏的影响因素进行单因素和多因素分析。结果179例患者中,术后发生吻合口漏13例(7.26%)。单因素分析显示,直肠癌Dixon术后吻合口漏的发生与吻合口距肛门距离(<3 cm,P=0.043)、术前存在低蛋白血症(P=0.001)、不全性肠梗阻(P=0.004)、糖尿病(P=0.003)、术后使用解痉药物(P=0.003)及术后腹泻(P=0.002)有关,而与患者性别,年龄,BMI,肿瘤Dukes分期,病理类型,吸烟、饮酒史,术前合并症(高血压、心脏病),术前是否存在贫血,手术方式,是否预防性回肠造口,术后是否肛管减压无关(P>0.05)。多因素分析显示,术前低蛋白、不全性肠梗阻、糖尿病史、术后未使用解痉药物及腹泻是吻合口漏发生的独立危险因素。结论针对低位直肠癌根治术后发生吻合口漏的影响因素,术前纠正低蛋白血症,控制血糖平稳,术后予解痉药物、调节肠道功能等措施可以有效减少吻合口漏的发生。     

3．0TMRI在舌鳞状细胞癌术前诊断和临床评估中的应用价值

目的：探讨3．0 T高场强MRI成像技术在舌鳞状细胞癌术前诊断和临床评估中的应用价值。方法：回顾性分析本院经手术和病理证实为舌鳞癌的26例病例术前3．0 T MRI影像资料。结果：3．0 T MRI可以清晰显示舌鳞癌及其侵犯的范围,同时了解颌下及颈部淋巴结情况,对TN分期具有重要意义。结论：3．0 T MRI对舌鳞癌的显示和诊断具有高分辨率、多方位及多序列成像优势,可以很好地显示舌鳞癌发生的位置、大小、病变侵及范围以及扩散途径,有助于术前病变性质的判断及肿瘤分期的评估。舌鳞癌检查首选高场强MRI。

近似人病理生理过程动物脂肪肝模型的综合建立方法

Objective To establish animal model of fatty liver similar with human pathophysiology used for the study of imaging quantitative diagnosis or verification of medicine curative effect. Methods Forty-five New Zealand white rabbits were used in this study. They were divided randomly into five groups : 10 rabbits in normal control group, 10 rabbits in experiment group 1,10 rabbits in experiment group 2,10 rabbits in experi-ment group 3,and remaining 5 rabbits were in a supplement group. Rabbits in normal control group were given free access to normal food and water for 9 weeks. Rabbits in the experimental groups were fed a high-fat and high-sucrose diet for 3,6,and 12 weeks,respectively. Rabbits in the supplement group were fed the same diet as the experimental groups. Liver specimen stained with HE and Sudan Ⅳ was examined histological. Results The success rate of hepatic steatotie models was 87 % (39 of 45 ) ;mortality was 13 % (6 of 45 ). There were 10 nor-mal livers, 10 mildly fatty livers, 9 moderately fatty livers, and 10 severely fatty livers in results (stained with HE), and the rate of conforming to Sudan Ⅳ was 75%. Conclusion The animal model of fatty liver with differ-ent severity can be established by being fed a high fat, high sucrose and alcohol diet.
