股后肌间平滑肌肉瘤一例

病倒男，54岁。以右肌后方复发性巨大溃破性包块伴疼痛半年入院。患者于十年前，无意中发现右大腿后方有一杏核大小无痛性包块．未就诊检查。四年前包块增大至鸡蛋大小，伴有轻度触压痛，在我院行手术完整切除炮滑有包膜之肿瘤．肉眼诊断为纤维瘤。术后一年发现原手术部位复性包块，生长速度快．行走活动时有痛感，检查见大腿中段后侧拳头大包块，边缘不清、

新辅助化疗联合股四头肌间室切除及功能重建术治疗恶性纤维组织细胞瘤疗效观察

目的探讨新辅助化疗联合股四头肌间室切除及功能重建术治疗股四头肌恶性纤维组织细胞瘤(MFH)的方法和效果。方法27例MFH患者,其中初治患者17例,复发病例10例,均行新辅助化疗与股四头肌间室切除及功能重建术。结果均予保留患肢,随访18～66个月。局部复发0例,5年生存21例(78%),其中无瘤生存18例(67%)。结论新辅助化疗联合股四头肌间室切除及功能重建术治疗MFH效果满意。

Proteome Profiles of Longissimus and Biceps Femoris Porcine Muscles Related to Exercise and Resting

Exercise affects muscle metabolism and composition in the untrained muscles. The proteome of muscle tissue will be affected by exercise and resting. This is of economic importance for pork quality where transportation relates to exercise of untrained muscles. Rest reverses exercise effects. The objective of this research was to develop potential protein biomarkers that predict the optimal resting time after exercise related to optimal pork quality. Ten litters of four female pigs were within litter allocated to the four treatment groups： exercise by running on a treadmill for 27 minutes followed by rest for 0, 1, or 3 h; control pigs without exercise. Proteome profiles and biochemical traits measuring energy metabolism and meat quality traits expected to be related to exercise were determined in the Longissimus and the Biceps femoris of the pigs. The results indicated associations between protein abundances in muscles and exercise, resting, and biochemical traits.

AO技术治疗犬股骨远端骨折的体会

AO技术,即常规骨折内固定技术,其是在上世纪五十年代发展起来的治疗骨折的新兴技术,近十几年来,在AO技术的基础上发展出BO技术,即为生物学内固定技术。AO技术的原则为:骨折的解剖复位、绝对可靠的符合生物力学的坚固固定、骨折局部血供的保护和早期骨折邻近关节的活动[1]。
