阐述了时相与阴阳的关系,阴阳昼夜的盛衰转换与经脉循行、气血流注密切相关;对传统流注说和任督为主的阴阳循环说进行了分析,认为子午流注阴阳盛衰转换在妇科学中有重要意义,子午流注所指出的4个较重要的时期与月经周期中的4期(行经期、经后期、经间排卵期、经前期)相关。重视研究日相阴阳太极钟的变化,将能更加深入地认识月经周期中阴阳消长转化的规律变化,从而推动中医妇科学向前发展。 相似文献

Zusammenfassung Die Pneumatosis cystoides intestinii (PCI), das Auftreten submuköser oder subseröser, gasgefüllter Zysten in der Wand des Gastrointestinaltrakts, tritt als seltene Erkrankung ohne eindeutige Geschlechtspräferenz vorwiegend in der 3. bis 5. Lebensdekade auf. Atiopathogenetisch werden unterschiedliche Faktoren diskutiert, am wahrscheinlichsten ist eine bakterielle Ursache (Clostridium perfringens) in Verbindung mit einer minimalen Unterbrechung der Mukosaintegrität. Eine pathognomonische Symptomatik gibt es nicht, das klinische Bild reicht von asymptomatischen Zufallsbefunden bis zur Hämatochezie. Die Diagnose wird durch den Nachweis der Gaseinschlüsse mittels Abdomenübersichtsaufnahme und Kolonkontrasteinlauf gestellt. Als Behandlungsmethoden für symptomatische Patienten stehen Sauerstofftherapie, Antibiotikagabe (Metronidazol) und in schweren Fällen die Resektion des betroffenen Darmabschnitts zur Verfügung.
Pneumatosis cystoides intestinalis (PCI), a condition involving submucosal or subserosal gas-containing cysts of the wall of the gastrointestinal tract, is a rare entity. It is mostly diagnosed between the third and fifth decades of life without a clear sexual predominance. Different aetiopathogenetic factors are under discussion, the most probable being a bacteriologic cause (Clostridium perfringens) in combination with minimal leaks in mucosal barrier. There are no pathognomonic symptoms; the clinical picture ranges from incidental findings to haematochezia. Diagnosis is based on plain abdominal film and X-ray following barium enema. Methods of treatment in symptomatic cases are oxygen and antibiotic (metronidazole) therapies and, in severe cases, resection of the diseased part of the intestine.相似文献

实验性急性胰腺炎肺内细胞凋亡状况及其意义的初步探讨 总被引:6,自引:3,他引:3
目的:探讨重症急性胰腺炎时肺内细胞凋亡的状况及其在肺损伤发病机制中的意义。方法:以不同浓度牛磺胆酸钠液逆行胰胆管注射造成大急急性水肿性胰腺炎(AEP)与急性坏死性胰腺炎(ANP)两种模型,测定血浆TNF-α与内毒素水平的动态变化,免疫组化检测肺内TNF-α的表达,并以TUNEL法结合激光扫描共聚焦显微镜检测肺组织切片内细胞凋亡的情况。结果:正常时大鼠肺内偶见淋巴细胞及纤维母细胞等发生凋亡,诱导AEP或ANP后凋亡细胞数量无明显变化。随着肺损伤的出现,少许浸润的炎细胞、肺泡上皮细胞及血管内皮细胞等发生了凋亡。凋亡指数(‰)在ANP组呈一过性下降,在ANP组表现为持续下降,在6h后各时点均显著低于AEP组相应值(P<0.05)。分析表明,ANP组血中TNF-α、内毒素含量的增加与凋亡指数的变化存在负相关(P<0.05)。结论:ANP时肺内浸润的以中性粒细胞为代表的大量炎细胞出现延迟凋亡,这种现象可能是肺损伤发生的重要前提,同时内毒素血症及TNF-α的过度合成可能是中性粒细胞延迟凋亡的部分原因。 相似文献

We report a patient who developed Henoch-Schönlein purpura (HSP) 13 years after he presented with IgA nephropathy (IgAN). In both HSP and IgAN renal biopsy most commonly reveals focal proliferative glomerulonephritis on light microscopy and immunofluorescence displays mesangial IgA deposits. In addition, patients with HSP or IgAN have elevated serum IgA levels, circulating IgA immune complexes, IgA-bearing lymphocytes, immunoglobulin-producing cells, and binding of IgG to glomerular components of similar molecular weight. The occurrence of both diseases in the same patient or the same families and the presence of immune abnormalities compatible with HSP or IgAN in relatives of patients with these diseases suggest a common pathogenesis. 相似文献

论中医病因、致病因素、邪气、邪之关系 总被引:2,自引:0,他引:2
张光霁 《浙江中医药大学学报》2007,31(6):676-677
邪是一切不正常、不正当的因素,邪气是邪的一部分,主要指六气异常以及疫疠之气等外感因素。两者可以独立于人体而存在,也可以进入人体,成为可能导致疾病的因素,即致病因素,邪(邪气)进入人体是致病因素,未进入人体不是致病因素。未导致疾痛的致病因素不是病因,已经引起疾病的致病因素是病因。 相似文献

Background Several clinical decision rules (CDRs) have been validated for pretest probability assessment of pulmonary embolism (PE), but the authors are unaware of any data quantifying and characterizing their use in emergency departments. Objectives To characterize clinicians' knowledge of and attitudes toward two commonly used CDRs for PE. Methods By using a modified Delphi approach, the authors developed a two‐page paper survey including 15 multiple‐choice questions. The questions were designed to determine the respondents' familiarity, frequency of use, and comprehension of the Canadian and Charlotte rules. The survey also queried the frequency of use of unstructured (gestalt) pretest probability assessment and reasons why physicians choose not to use decision rules. The surveys were sent to physicians, physician assistants, and medical students at 32 academic and community hospitals in the United States and the United Kingdom. Results Respondents included 555 clinicians; 443 (80%) work in academic practice, and 112 (20%) are community based. Significantly more academic practitioners (73%) than community practitioners (49%) indicated familiarity with at least one of the two decision rules. Among all respondents familiar with a rule, 50% reported using it in more than half of applicable cases. A significant number of these respondents could not correctly identify a key component of the rule (23% for the Charlotte rule and 43% for the Canadian rule). Fifty‐seven percent of all respondents indicated use of gestalt rather than a decision rule in more than half of cases. Conclusions Academic clinicians were more likely to report familiarity with either of these two specific decision rules. Only one half of all clinicians reporting familiarity with the rules use them in more than 50% of applicable cases. Spontaneous recall of the specific elements of the rules was low to moderate. Future work should consider clinical gestalt in the evaluation of patients with possible PE. 相似文献

The mistreatment of elderly is subject to various social constructions. On two geographically distinct Plains Indian Reservations which we call Lone Mountain and Abundant Lands, the abuse or neglect of elderly is construed as a health problem which is a dysfunction of the community as a whole. Both physical abuse and neglect are more common on the Lone Mountain Reservation, occurring in association with other indicators of community disorganization such as unemployment and substance abuse. On the Abundant Lands Reservation physical abuse was categorically denied and what neglect existed appeared to be a function of role strain, geographic dispersal, climate and terrain. We attribute differences in the prevalence of mistreatment of elders to variations in economic opportunities for younger residents. Examining the historical and present contexts of intergenerational relationships on the reservations, we discuss the implications of this study for social exchange theory and policy applications.This research was supported by the Gerontological Society of America AppliedThis research was supported by the Gerontological Society of America AppliedThis research was supported by the Gerontological Society of America AppliedThis research was supported by the Gerontological Society of America AppliedThis research was supported by the Gerontological Society of America AppliedThis research was supported by the Gerontological Society of America Applied 相似文献
