犬咬伤的诊治95例

近年来，犬咬伤人事件屡屡发生，在急诊外科疾病中所占比例逐年升高，我们自2003年6月至2006年6月共收治犬咬伤患者95例，其中发生狂犬病3例。结合本组病例谈谈我们的体会。     

118例儿童室性期前收缩的临床分析

目的 探讨病理性与非病理性室性期前收缩的心电图特征.方法 对比分析62例病理性室性期前收缩,56例非病理性室性期前收缩的心电图.结果 Ⅰ组室性期前收缩起源于右心室/右束支上部居多.结论 病理性室性期前收缩多起源于右心室/右束支上部,提示此标准可作为儿童病理性室性期前收缩的重要辅助诊断标准.     

胆胃通降片药理作用的研究

胆胃通降片根据清代“太和医室”中之秘方研制而成,已由西安国药厂生产。由半夏、龙胆草、大黄、广木香和枳实等药组成。用于消化不良、胃炎、便秘,胆囊炎等症,疗效较好。实验结果说明,本品毒性较低可非常显著地增强小肠推进运动,显著增高胃排空率,对胆汁分泌量虽未见明显     

吉林省革螨记录(15)(蜱螨亚纲:中气门亚目)

在研究螨原性疾病过程中,调查螨的种类和分布,发现吉林省革螨新记录4种,报道如下。Ⅰ.厉螨科Laelapidae1网状广厉螨(Cosmolaelaps reticuatusXuetLiang,1996)雌螨体黄色,卵圆形,长563~586(平均577)μm,宽391~437(平均404)μm。背板覆盖整个背面,具刚毛39对和2~4根附加毛,近基部     

马氏秘方“骨丸”治疗股骨头缺血坏死

股骨头缺血坏死是骨伤科的疑难病。近些年来，由于某些疾病的需要，长期使用激素及随意使用激素以致诱发本病，因而发病率大为升高。自1984年以来我们用马氏秘方骨丸治疗本病，以行气通络，活血止痛，扶正解毒为治法。内治方药为骨丸3号(含有血竭，石菖蒲等药)。     

不同持续时间的周期性压力对构建组织工程软骨的影响

Objective To determine the best duration for exerting the cyclic pressure under which the tissue-engineered cartilage is constructed. Methods Free chondrocytes isolated from rabbit articular cartilage were seeded into polylactic acid-co-glycolic acid(PLGA) scaffolds after expansion in vitro, and ran-domized into 4 groups. In Groups 1 to 3, chondrocytes were cultured under daily cyclic pressure (0 ～ 200 kPa, 0.1Hz) for 4 hours, 8 hours, 12 hours respectively; Group 4 was a control in which no pressure was exerted. In each group, after 2 weeks of culture, the tissue engineered cartilages were observed in vitro and assessed by his-tological staining of liE. Next, the content of DNA and the secretion of type Ⅱ collagen and GAG in cartilages were detected quantitatively. Results Under the daily cyclic pressure (0 ～200 kPa, 0.1 Hz), the scaf-fold-chondrocytes complex in the group of 8 hours got the largest volume, smooth, lucidus, and elastic surface, the most queuing chondrocytes, and the highest content of type Ⅱ collagen and GAG (P < 0.01). Conclusions Since chondrecytes are baro-senstive, the metabolism of chondrocytes can be affected by the time of cyclic pressure. Under the effect of 0 ～200 kPa, 0.1Hz, the daily cyclic pressure of 8 hours may be optimal for chondrocytes to multiply and synthesize extracellular matrixes such as type Ⅱ collagen and GAG.     

原发性中枢神经系统淋巴瘤8例诊治分析

目的探讨原发性中枢神经系统淋巴瘤的诊断及治疗方法。方法分析8例原发性中枢神经系统淋巴瘤的临床特征、诊治情况。结果单病灶7例,多病灶1例。病理检查为B细胞来源者7例,T细胞来源1例,平均生存时间18.4个月。结论原发性中枢神经系统淋巴瘤多为术后病理确诊,孤立病灶可行手术切除,术后化疗加放疗可延长患者的生命,而弥漫分布型不宜手术切除,可进行化疗及放疗。
