血液流变学用于原发性肾小球疾病诊疗的价值

观察４１例原发性肾小球疾病患者（其中肾病综合征９例，慢性肾炎肾功正常１７例，尿毒症１５例）的血液流变学指标。结果表明：肾病综合征的红细胞变形能力减低及红细胞的凝集性增加，表现为全血粘度增加；尿毒症组血液粘度降低。多因素回归分析表明：血液粘度与红细胞压积、纤维蛋白原及血沉Ｋ值正相关，与血沉负相关。由于高粘血症易导致血栓形成，故早期应用降粘药物可能成为肾病综合征的治疗方法之一。从肾炎组和尿毒病的血液流变性改变来看，血粘度随着肾功能减退而降低，它可能是预后判断一个指标。

不同鞋条件对后跟着地跑者跟腱负荷特征的影响

目的 探究不同鞋条件（极简鞋和传统跑鞋）对跑步时跟腱负荷特征的影响。方法 招募16名健康男性后跟着地跑步爱好者,要求其以3.16~3.50 m/s速度在两种鞋条件下完成跑步实验。采用超声影像仪获取跟腱横截面积成像。采用运动捕捉系统和三维测力台获取踝关节矢状面运动学和地面反作用力数据,并计算踝关节和跟腱的力学参数。采用配对样本t检验比较两种鞋条件对各因变参数（踝关节角度、触地角度、跟腱力、应力、应变等）的影响。结果 与传统跑鞋相比,穿着极简鞋时的足触地角度显著降低39.9%。同时,踝关节力矩、跟腱力峰值、跟腱负载率峰值和平均负载率均显著增加,而达到跟腱力峰值的时间显著减小。穿着极简鞋时的跟腱应力峰值、跟腱应变峰值及其应力率和应变率峰值也显著增加。结论 习惯穿着传统跑鞋并采用后跟着地的跑者在穿着极简鞋后显著增加了跟腱的负荷特征,建议该类跑者循序渐进地过渡至极简鞋,以适应性地提高跟腱承受负荷的能力。

Die Wand der primären Hydrozele des Kindes

Zusammenfassung Die primäre Hydrozele des Kindes ist charakterisiert durch ein ausgeprägtes Wandödem, als dessen Ursachen fehlende Lymphgefäße und venöse Stauung angesehen werden müssen. Die morphologischen und klinischen Unterschiede zwischen Säuglingsund Klemkindhydrozelen sprechen für die Annahme, daß das pathologisch gesteigerte Filtrat der verquollenen Lamina parietalis der Tunica vaginalis testis bei vorzeitigem Verschluß des Processus vaginalis peritonei nicht in die Bauchhöhle drainiert werden kann und somit zur Hydrozele führt.

The wall of primary hydrocele in childhoodLight and electron microscopic findings

Summary Hydroceles of infants and children are characterized by edematous wall-thickening, caused by lacking lymph vessels and venous congestion. The morphologic and clinical differences between hydroceles of infants and children favor the following hypothesis: Pathologically increased filtration of fluid from the parietal tunica vaginalis can't be drained into the peritoneal cavity because the processus vaginalis closes too early and gives raise to hydrocele.

Vascular tumors of bone: A study of 17 cases other than ordinary hemangioma,with an evaluation of the relationship of hemangioendothelioma of bone to epithelioid hemangioma,epithelioid hemangioendothelioma,and high-grade angiosarcoma

Cases filed as vascular tumor of bone other than ordinary hemangioma were reviewed. They were included in the study if there was adequate histologic material and clinical information, clear evidence of bone origin, and at least 5 years follow-up. The study group comprised 17 cases, of which 13 were categorized as hemangioendothelioma of bone, 1 as epithelioid hemangioendothelioma, and 3 as high-grade angiosarcoma. Hemangioendothelioma of bone had growth patterns varying from vasoformative to solid, but well-formed vessels were present in at least some area in all cases. The cells generally had a rounded, epithelioid character, regular nuclei, and relatively few mitotic figures; occasional features included spindle cells and scattered enlarged, hyperchromatic or pleomorphic nuclei. Lymphoplasmacytic and eosinophilic inflammatory infiltrate ranged from prominent to slight or absent, and myxoid or hyaline stroma was never more than focal. Epithelioid hemangioma could not be separated from hemangioendothelioma of bone. The single epithelioid hemangioendothelioma for the most part had cords of relatively uniform epithelioid cells in a prominent myxoid stroma but focally demonstrated an angiosarcoma-like appearance, with irregular vascular spaces and marked nuclear pleomorphism. The high-grade angiosarcomas exhibited predominantly irregular vasoformation combined with solid areas, diffuse nuclear hyperchromatism and pleomorphism, and, in 2 cases, numerous mitotic figures (the third case had only a small biopsy and a postradiation amputation specimen). Of the hemangioendotheliomas of bone, 7 were unicentric and 6 were regionally multicentric either concurrently or sequentially. Three patients had intraosseous local recurrence, 2 had discontinuous regional skin or soft tissue involvement (including the popliteal artery in 1), and 1 had a solitary lung metastasis, but none died of tumor. The patient with epithelioid hemangioendothelioma had multicentric tumors in widely separated bones and died with liver and lung metastases. Two of the high-grade angiosarcomas were unicentric, and the third was regionally multicentric, with a popliteal artery-soft tissue component as well. All 3 of these patients died with metastases in various sites.     

Age of puberty: data from the United States of America

In an attempt to determine whether the secular trend toward an earlier onset of puberty has continued over recent decades in the United States of America, published reports concerning the age of attainment of pubertal events have been reviewed. Such reports are very limited and vary in both design and inclusive ages of study subjects. Among females, two recent large cross-sectional studies indicate that fifty percent of females in the United States attain Tanner breast stage 2 at 9.5 to 9.7 years of age. This is younger than previously thought, although adequate earlier studies of girls in the United States are not available for comparison. These two studies also indicate that about 14% of girls attain Tanner stage 2 while 8 years of age; one study extends earlier reporting that about 6% exhibit onset of breast development while 7 years of age. There is no evidence that the age of menarche or the attainment of adult (Tanner 5) breast development has decreased over the past 30 years. The data also suggest an earlier onset of Tanner stage 2 pubic hair but no change in attainment of stage 5. Among males, pubic hair may be appearing at younger ages, but data are inadequate or too inconsistent to allow firm interpretation. The lack of standardization of genital criteria of pubertal onset in the male makes any conclusions regarding secular trends impossible. In summary, earlier secular trends over recent decades related to better health, improved nutrition or socio-economic status, or any putative influence by endocrine disrupters cannot be verified.
