疑难病辨治思路与方法

认为疑难病是诊断疑惑、治疗困难的病证。疑难病的治疗贵在辨证，其辨证方法主要是从症辨证，通过辨主症、辨兼症、辨客症确定证名，然后随证论治。提出疑难病的病因以痰、瘀、郁、虚四者为主，治疗应着重治痰、治瘀、治郁、治虚，或兼而治之，并要求做到有胆有识，有方有守，如此方可取得较好疗效。     

四川省部分地区主粮中杂色曲霉菌及其毒素的污染调查

通过对四川省部分地区大米和小麦两种主粮中杂色曲霉菌（Ａ．ｖ）和杂色曲霉素（ＳＴ）污染调查，结果表明在大米和小麦中，Ａ．ｖ污染率分别为５．５％和１０．５％；ＳＴ污染率为５３．４％和６５．８％；ＳＴ平均含量为１５．５μｇ／ｋｇ和５８．６μｇ／ｋｇ。对不同地区和不同贮藏期粮食进行分析，Ａ．ｖ检出率越高，粮食中ＳＴ污染率和含量越高；贮藏期延长，Ａ．ｖ和ＳＴ检出率及ＳＴ含量增高。实验产毒表明所有Ａ．ｖ菌株均能产生ＳＴ，平均产毒量达７１９０．２μｇ／ｋｇ，证实Ａ．ｖ是ＳＴ形成的主要菌种     

高效毛细管蛋白电泳法对鸡内金和穿山甲的鉴别

目的 对鸡内金及其混淆品,穿山甲及其炮制品两种动物药材进行鉴别.方法 采用高效毛细管电泳(HPCE)法对药材中酸性、中性和碱性蛋白进行电泳分析.电解缓冲液为150mmol·L-1硼酸盐溶液(pH8.5);电压为20KV;温度20℃;紫外检测波长200nm;重力进样5s.结果 鸡内金与其混淆品之间蛋白质HPCE图谱有明显的差异,可有效地加以区分.穿山甲与炮制品之间中性蛋白和碱性蛋白提取液的HPCE图谱基本一致,而酸性蛋白提取液的HPCE图谱有一定差异,可有效加以区分.结论 高效毛细管电泳法可作为中药鸡内金,穿山甲的生药鉴别方法.     

La neuropsychologie cognitive et les délires d’identification des personnes

Following publication of the three classic misidentification syndromes (Capgras delusion, Capgras and Reboul-Lachaux, 1923; Frégoli delusion, Courbon and Fail, 1927; and intermetamorphosis, Courbon and Tusques, 1932), the most popular theoretical explanations were psychodynamically-based. More recently the precepts of cognitive neuropsychiatry have prevailed. Models of face recognition such as that of Bruce and Young (1986) suggest three stages in the process, in two of which may lie the origin of intermetamorphosis (FRU stage) and the Frégoli delusion (PIN stage); but the Capgras delusion cannot be easily accommodated. Ellis and Young (1990) introduced the element of the emotional response to known faces which manifests itself in autonomic responses. Ellis and Young suggested that it is a disruption to this emotional route that underlies the Capgras delusion. Experimental tests of this hypothesis provide confirming evidence and other studies with patients showing Capgras delusion further elucidate our understanding of face recognition.     

维吾尔药琐琐葡萄的生药学鉴定

目的：对维吾尔药琐琐葡萄进行生药学鉴定，为开发利用该药材提供鉴别依据。方法：对琐琐葡萄药材性状、组织构造与粉末药材进行鉴定。结果：山葡萄和琐琐葡萄的显微特征极为相似，但二者有明显区别。结论：葡萄属植物的形态特征虽然相似，但有明显区别。此研究结果可为制定琐琐葡萄的质量标准提供依据。     

大叶紫薇叶中熊果酸的分离纯化及结构

利用溶剂萃取、薄层层析对大叶紫薇提取物中三萜化合物进行分离,通过 DSC,UV, IR和HPLC/MS对分离产物中具有降血糖的成分 3 进行结构分析,结果表明:以氯仿∶丙酮为展开剂,可在硅胶板中将大叶紫薇中三萜化合物有效分离。对分离出的成分 3,DSC测定其熔点为 283~287 ℃,焓值为43 727 J/g;UV最大吸收波长为 206 nm; MS测定其相对分子质量为 457; IR光谱符合乌苏果烷型结构.经分析,具有降血糖的成分3即为熊果酸.

Examination of postmortem animal interference to human remains using cross-species multiplex PCR

Postmortem animal interference may be confused at first sight with injuries of vital origin, thus arousing suspicion of external violence preceding death. A reliable classification of the origin of such doubtful injuries is of crucial importance, a fact that is especially true for the investigation of suspected homicide and/or mammade body mutilation after death. In forensic pathology, the identification of injuries as caused by animals postmortem and the classification of a particular species as responsible for a specific injury pattern under question is usually done by forensic pathologists with vast practical experience and special knowledge of the appearance and morphology of tooth marks of carnivores and rodents, respectively. However, a molecular biological investigation of such wounds could provide genetic evidence that an injury pattern present on a corpse was truly caused postmortem by animal interference and thus support the pathologist's expertise. For this purpose, we developed a panel of small species-specific short-tandem repeat systems (<150 bp) for animals typically involved in postmortem scavenging of human remains, such as dogs and cats as well as wild-living rodents (mice and rats) having possible access to death scenes inside apartments or buildings. A specific and sensitive cross-species multiplex polymerase chain reaction was then established including the species-specific animal markers, thus enabling the genetic identification of wounds caused postmortem by different animals on human remains. This study was presented at the Sixth International Symposium in Advanced Legal Medicine (ISLAM), Hamburg, Germany, September 2006.     

南五味子类药材的鉴别研究

目的 为南五味子药材的鉴定提供依据。方法 用性状鉴别、扫描电镜和薄层色谱方法对不同产地华中五味子及其近缘种绿叶五味子、翼梗五味子和红花五味子果实进行生药性状、种子表面微形态和薄层鉴别。结果 依据种皮表面的微形态特征可以将华中五味子、红花五味子、绿叶五味子及翼梗五味子分为3个类型。去氧五味子素(五味子甲素)(deoxyschisandrin)、五味子酯甲(schisantherin A)的薄层定性表明产于陕西平利、河南栾川、山西阳城、湖南衡山的华中五味子、绿叶五味子和红花五味子果实中都含有五味子酯甲和五味子甲素；翼梗五味子果实中仅含有五味子酯甲，而甘肃小陇山、陕西留坝产华中五味子果实中检测不到这两种成分。结论 不同产地华中五味子、红花五味子、绿叶五味子及翼梗五味子的干燥果实可以依据种皮表面的微形态特征和薄层色谱结果加以鉴别。
