基于Internet的遗传疾病登记、随访系统的设计与实现

本系统通过以Internet网为平台,将传统的医院/患者(咨询者)的遗传随访模式转为医院/Internet网/患者(咨询者)的新医疗模式,该系统会大大提高遗传随访的及时性和便利性;同时,会有利于遗传登记的开展,也有利于随访资料的保存。     

茶色素对冠心病及高血压病病人血小板功能的影响

目的：探索茶色素对冠心病、高血压病病人血小板功能的影响。方法：冠心病病人３６例（男性２１例，女性１５例；年龄６４±ｓ４ａ）；高血压病病人３０例（男性１８例，女性１２例；年龄５８±８ａ）。采用茶色素２５０ｍｇ，ｐｏ，ｔｉｄ，３０ｄ为一个疗程。结果：治疗后ＴＸＢ２下降，６－ｋｅｔｏ－ＰＧＰ１α上升，ＴＸＢ２／６－ｋｅｔｏ－ＰＧＦ１α比值下降（Ｐ＜０．０１或Ｐ＜０．０５），ＧＭＰ－１４０下降（Ｐ＜０．０５），ＰａｇＴ，ＰａｄＴ下降（Ｐ＜０．０５）。结论：茶色素具有降低血小板表面活性作用，抑制血小板聚集和粘附，抗血栓形成，改善微循环，对冠心病和高血压病病人起到积极的防治作用。     

大鼠气管上皮细胞体内—体外转化模型的研究

本研究建立了大鼠气管上皮细胞体内－体外转化模型，大鼠气管内滴注苯并芘，三天后处死大鼠，消化气管上皮细胞，接种于无血清完全培养基。细胞形成集落后，换为选择培养基继续培养五周，统计转化率。结果显示，２５ｍｇ／ｋｇ和５０ｍｇ／ｋｇ的苯并芘可诱导大鼠气管上皮细胞转化及微核增加，用同样方法研究了煤焦沥青提取物，结果表明，剂量为８ｍｇ／ｋｇ和２５ｍｇ／ｋｇ的煤焦沥青提取物能明显诱导大鼠气管上皮细胞转化。     

解磷注射液救治急性有机磷农药中毒34例临床报告

将急性有机磷农药中毒患者69例随机分为2组,一组主要应用解磷注射液治疗(新疗法34例),另一组(35例)主要应用阿托品治疗。两组治愈率分别为97.1％及77.1％,疗效比较差异显著(P<0.05)。新疗法的优点是起效快,作用持久,疗程短(两组比较P<0.001),副反应轻,值得推广应用。并就应用方法及注意事项等作了探讨,也强调了早期足量用药的重要性。     

甘草黄酮的提取分离和含量测定

目的：充分利用甘草资源。方法：从提取过甘草酸的废渣中提取甘草黄酮并进行含量测定。结果：用碱酸处理和用大孔树脂处理黄酮含量高，收率也高。结论：从甘草废渣中提取甘草黄酮具有较好的社会效益和经济效益     

组织扩张术皮肤胶原的代谢改变

目的：研究常规扩张（ＩＴＥ）和持续快速扩张（ＣＴＥ）对皮肤胶原代谢的影响。方法用白色小家猪制作组织扩张术动物模型，用Ｇｏｒｄｅｌａｄｚｅ法测定血清和扩张组织的羟脯氨酸（ＨＰ）含量，藻酸盐印模材膜片法测量标记区面积；光镜测量真皮厚度。结果：ＩＴＥ组血清ＨＰ含量升高，０．８倍，ＣＴＥ组升高１．２倍，ＩＴＥ和ＣＴＥ组皮肤含量与正常皮肤相同，组织中ＨＰ总量均明显升高，持续扩张皮瓣组（ＣＴＥＦ）术后４ｗｋ皮     

胸部螺旋CT扫描技术及临床应用

作者采用了不同的人体体模和临床应用实验，对常规和螺旋ＣＴ扫描进行了比较研究。结果显示：与常规ＣＴ比较，螺旋ＣＴ图像无失真，变形。分辨率略差于常规ＣＴ。改变扫描条件和床速，图像质量无明显改变。改变扫描图像数学处理模式后，分辨率有所增加，但螺旋扫描仍冰及常规扫描。在临床应用上，螺旋扫描有许多优点。如何采用一次屏气技术，对病人某一脏器检查只需一次连续扫描。扫描速度快，不易产生运动伪影，所选脏器的扫描无盲     

Influences on Food Selection of Women on High- and Low-Fat Diets

There is evidence that long-term maintenance of a low-fat diet reduces preference for high-fat foods. Sensory evaluation of the taste of fat, and preference for high and low-fat foods were studied in a group of former participants in a randomized dietary intervention trial aimed at lowering fat consumption. Intervention subjects consuming less than 25% of daily calories as fat and control subjects consuming more than 35% of daily calories as fat agreed to be in a "taste perception" study. In Study 1, subjects tasted 20 dairy solutions containing different levels of fat and sugar. Subjects rated the perceived intensity of fat taste, and of liking, for each of the solutions. In Study 2, subjects were asked to taste and rate 4 high-fat and 4 low-fat snack foods, and were then allowed to freely consume these foods in a preference test. Intervention and control subjects were similar in their sensory evaluation of the taste of fat in Study 1. In Study 2, intervention subjects reported a reduced hedonic rating of the taste of high-fat snack foods compared to control subjects, yet intervention subjects consumed the same amount of high-fat snack foods as control subjects. We conclude that a successful outcome in a dietary intervention may be due to social and cognitive factors, in addition to potential changes in hedonic response to fat.     

肝动脉化疗栓塞术治疗肝癌的临床与病理的联系

作者将9例肝动脉化疗栓塞术(HAE)后二期切除的肝癌标本,多处切片作病理检查,结合病人的临床过程分析HAE的治疗作用,肝癌包膜对HAE的影响,HAE的效果及HAE后手术的时机等。作者认为,HAE对肝癌的治疗效果是姑息性的,故HAE后应争取在30～60天内再手三术探查,争取切除肿瘤。否则,HAE后肝癌复发的可能性极大。
