为了探求一种更为合理的全厚皮片移植方法,我们在按形切取全厚皮片后应用L-形皮瓣转移即时闭合供区创面47例,取得满意效果。该术式改变了既往梭形切取全厚皮片、直线拉拢缝合的传统方法,而按照受区创面的形状、大小在供区适当的方位切取相应形状、大小的全厚皮片;同时灵活应用L-形皮瓣转移,将张力小的周边组织转至创面,从而即时闭合供区创面。这不仅节约了组织量,增加了切取量;而且操作简单、转移灵活。由于张力较小,术后切口瘢痕不显著。从而也改进了全厚皮片的切取方法。 相似文献

[Purpose] The purpose of this study was to examine the effects of closed kinetic chain
exercises (CKCEs) and open kinetic chain exercises (OKCEs) with elastic bands on the
electromyographic activity of patients with degenerative gonarthritis. [Subjects] The
study subjects were 30 degenerative gonarthritis patients who were divided into a CKCE
group (CKCEG, n=10), an OKCE group (OKCEG, n=10), and a control group (CG, n=10).
[Methods] The CKCEG and the OKCEG performed exercises with elastic bands, and the CG took
part in a quadriceps strengthening exercise. All three groups performed the exercises
three times per week for four weeks. The electromyographic activities of the subjects’
vastus medialis (VM), rectus femoris (RF), vastus lateralis (VL), semitendinosus (ST), and
biceps femoris (BF) muscles were measured and compared. [Results] Within-group comparisons
revealed that the electromyographic activities of the VM, RF, VL, ST, and BF muscles
increased significantly in the CKCEG. The OKCEG displayed significant increases in the
electromyographic activity of the VM, RF, ST, and BF muscles, and the CG showed
significant increases in the electromyographic activities of the RF, VL, ST, and BF
muscles. In between-group comparisons after the intervention, the electromyographic
activities of the VM, RF, and VL muscles of the CKCEG were significantly higher than those
of the CG. The electromyographic activities of the VM, RF, and ST muscles of the OKCEG
were significantly higher than those of the CG. [Conclusion] We consider CKCEs with
elastic bands are an effective intervention for increasing the electromyographic
activities of the VM, RF, VL, ST, and BF muscles of degenerative gonarthritis patients,
and OKCEs with elastic bands are an effective intervention for increasing the
electromyographic activities of the VM, RF, ST, and BF muscles of degenerative
gonarthritis patients. 相似文献

均匀导电球头模型中偶极子电位的一般性解析解 总被引:7,自引:0,他引:7
尧德中 《中国医疗器械杂志》1994,18(6):314-318
位于均匀容积电体球中的偶极子电位的计算是脑电、脑磁理论研究中的基础性工作,文献中尚未给出一般情况下的解析解。本文导出了以Legendre级数和直角坐标两种方式表示的这一问题的一般性解析解,所得公式既适合于球面上也适合于球内位场的计算,而且没有任何不确定性,从而为进一步开展有关研究奠定了基础。 相似文献

This paper reviews some of the recent randomised trials on acupuncture published in the literature, with particular reference to the definition of placebo (control), sham acupuncture and real acupuncture. Response rates of 30, 50 and 70% of placebo, sham and real acupuncture respectively, are suggested for the groups of patients studied. The statistical methodology necessary in the design of acupuncture trials, in order to detect differences of this order of magnitude, is discussed. If the postulated response rate had been envisaged at the onset of the trials here reviewed, then the majority of these trials have very low power at a conventional 5% level of significance. It is emphasised that one cannot necessarily conclude from trials which produce statistically non-significant results that acupuncture (when compared with placebo for example) is ineffective. The paper suggests that meaningful comparisons between alternative treatments may be made by using ‘pain free intervals’ with subsequent analysis using life table techniques. Tables are provided for determining appropriate patient numbers. 相似文献

A case of traumatic separation of the lower humeral epiphysis due to birth injury is reported. In the past 20 years, only 3 similar cases have been reported in the English literature. Following a manipulative reduction and immobilization of the arm in a collar and cuff for 3 weeks the baby made an uneventful recovery. When seen 10 months after injury, the baby had regained full movements of the elbow except for the last 10 ° of extension. 相似文献

We report 9 women in the third trimester of pregnancy who were severely injured in road traffic accidents. There were 3 accelerated labours and half the babies died. Immediate obstetric interference was often impractical and did not improve fetal survival. Noteworthy injuries of the central nervous system were associated with very high fetal mortality. Fractures of the pelvis were not nearly as disastrous as the literature suggests. The first consideration in management should be the well being of the severely injured mother, since the injuries that would kill the fetus are not likely to be amenable to surgery. The only justification for intervention for the sake of the fetus that survives the moment of impact is to salvage it from its dying mother's body. 相似文献
