对《诸病源候论》毒邪症状界定的分析

《诸病源侯论》论毒邪篇幅之多,明目之清,发前人所未发,打破传统束缚,注重临床实际。如其提出毒邪判断要以阴阳为纲;毒邪向内为病重,向外为病轻;赤白为轻,青紫黑为重;过肘膝为重,以及伤肠胃心肝脾肾均有不同的症状特征,提示了六淫从化于毒,毒邪与六淫有不同表现等问题,值得一读。     

Anal Tonometry in the Neonatal Period for the Diagnosis of Hirschsprung's Disease

ABSTRACT. A double balloon technique was used for anal tonometry in 22 infants. The weight was less than 2500 g in 10 of the infants. Ileus or delayed passage of meconium was seen in 9 infants. Thirteen infants had not revealed any symptoms of intestinal obstruction during the first week of life. In all cases, except one, it was possible to demonstrate reflexes from the internal anal sphincter. In 18 infants normal curves were registered from the internal anal sphincter. None of these developed Hirschsprung's disease. In 3 infants a pathological pattern of contractions of the internal anal sphincter was demonstrated. Two of them proved to have Hirschsprung's disease. In the third case normal reflexes were registered after one year. Possibly the innervation of rectum and the internal anal sphincter was disrupted during the neonatal period in connection with enterocolitis and ileus, thus representing a reversible case of achalasia.     

Rapidly Progressive Toxic Leukoencephalomyelopathy with Myelodysplastic Syndrome: a Clinicopathological Correlation

Neurological disorders induced by long-term exposure to organic solvents typically have a slowly progressive clinical course, which may be arrested or even reversed following discontinuation of exposure. We report an unusual case of rapidly progressive toxic leukoencephalomyelopathy in a 29-year-old man who had worked at a chemical factory that used toluene for the manufacture of nylon 66 for 5 years. He presented with progressive weakness of legs, recurrent seizures, and cognitive decline. Widespread white-matter changes in the brain and spinal cord, and myelodysplastic syndrome were noted. He died 6 months after the onset of his symptoms, and autopsy showed discrete multifocal demyelination and necrosis in the central nervous system, and dysplastic cells of erythroid, myeloid, and megakaryotic lineages in blood vessels. The co-occurrence of leukoencephalomyelopathy and myelodysplastic syndrome highlights the vulnerability of the white matter and bone marrow to injury from organic solvents. Intravascular congestion of dysplastic hematopoietic cells might have led to his unusually rapid progression of leukoencephalomyelopathy.     

Effect of linoleic acid, linoleic acid anilide, and arachidonic acid on the expression of adhesion molecules on human neutrophils

The effects of linoleic acid, linoleic acid anilide, and arachidonic acid on the expression of CD11b/CD18, CD11c/CD18 integrins and l-selectin on human neutrophils were studied by flow cytometry in a whole blood assay. None of these compounds had any effect on the basal expression of CD11b, CD11c, or l-selectin in the concentration range of 20–100 μM. However, linoleic acid at a concentration of 1000 μM slightly up-regulated CD11b and CD11c by a factor of 2.1 and 1.7, respectively. Linoleic acid, linoleic acid anilide, and arachidonic acid did not affect the formyl-methionyl-leucyl-phenylalanine induced up-regulation of CD11b or CD11c. However, linoleic acid and linoleic acid anilide slightly inhibited the phorbol myristate acetate (PMA)-induced expression of CD11b, which was decreased by 27 and 21% at concentrations of 100 and 1000 μM, respectively. Likewise, arachidonic acid at 40 μM inhibited the PMA-induced expression of CD11b by 19%. Our results suggest that linoleic acid, linoleic acid anilide, and arachidonic acid do not dramatically affect the expression of leukocyte adhesion molecules in a whole blood assay.

阿帕替尼对Her2阴性晚期胃癌患者的治疗效果及毒副作用分析

目的:探究Her2阴性晚期胃癌患者采用阿帕替尼进行治疗的疗效及毒副作用。方法:按照不同治疗方法将本院就诊的Her2阴性晚期胃癌患者分为阿帕替尼组(AP组)和替吉奥组(TI组),各46例,分析比较两组患者的临床疗效、生活质量、毒副作用及远期疗效。结果:治疗后,AP组11例、TI组6例患者出现部分缓解,AP组患者RR、DCR数值明显比TI组高(P<0.05);AP组患者生活质量明显优于TI组(P<0.05)。AP组和TI组患者均出现血小板减少、蛋白尿、肝功能异常等不良反应,但未出现Ⅳ级毒副作用,其中AP组患者高血压、血小板减少的发病率分别为63.52%、76.73%,TI组患者发病率分别为62.45%、78.11%, AP组出现毒副作用的患者人数与TI组比较无明显差异(P>0.05)。随访3年结果显示,AP组患者3年生存率为10.86%,TI组患者为0,AP组患者总生存率明显高于TI组(P<0.05)。结论:阿帕替尼对Her2阴性晚期胃癌患者的临床疗效及远期治疗效果较佳,虽然治疗后也会出现一定的毒副作用,但与替吉奥治疗后出现的毒副作用相近,且患者身体承受程度较佳。阿...     

不同造模方法所致“热毒血瘀证”模型家兔血液流变学改变的比较研究

本文通过金葡菌、大肠杆菌内毒素、地塞米松加内毒素等三种不同的攻毒方法复制了“热毒血瘀证”的动物模型。结果提示三种模型在血凝学指标上均表现为KPTT、PT明显缩短,而在血液流变学指标上则有不同。金葡菌所造模型表现为明显的高粘状态,内毒素模型则表现为明显的低粘状态,地塞米松加内毒素模型则改变不明显。     

An international registry for toxic inhalation and pulmonary edema: notes from work in progress

Acute toxic inhalation by irritant, and particularly oxidant, gases has until recently been considered to be no more complicated conceptually than a chemical burn of the epithelial surface. More recently, however, toxic inhalation has been appreciated to be a complex process involving biochemical, morphological and functional changes which are quantitatively similar, although inducible by different agents. Recent advances in pulmonary pathophysiology, inhalation toxicology, and particularly endothelial biology have clarified the events occurring at the moment of, and immediately following, exposure to oxidant gases. Studies of the pathophysiologic mechanisms associated with toxic inhalation by oxidant gases have been relatively static, however. Implications of recent findings in related fields illuminate the pathophysiology of toxic inhalation. Several principal speakers in this workshop are collaborating in an effort to develop a research facility for the study of toxic inhalation injury. This would be an international registry to serve as a teaching and research facility for documentation of cases of occupational and environmental toxic inhalation, considered as lung injury resulting from the inhalation of a toxic substance in a workplace setting or an uncontrolled release affecting residents of a community. The registry, as proposed, would encourage submissions by clinicians and institutions of a data set on each patient and on each incident; the registry would further encourage long-term follow-up of subjects and documentation of residual effects.Work presented at the 23rd Congress on Occupational and Environmental Health in the Chemical Industry (Medichem 1995) The Chemical Industry as a Global Citizen - Balancing Risks and Benefits, 19–22 September 1995, Massachusetts Institute of Technology, Cambridge, Massachusetts
