该随机临床试验的主要目的是研究慢性腹壁疼痛病人接受超声引导下腹横肌平面(transversus abdominis plane,TAP)阻滞与超声引导下激痛点注射(trigger point injections,TPI)治疗,术后3个月随访时疼痛数字评分法(nRS)评分情况。主要结局评估方法是使用意向性分析(ITT)方法,比较TAP组和TPI组在随访第3个月时nRS评分的差异。共纳入60例病人,以1:1的比例随机分入超声引导下TAP阻滞组(n=30)或超声引导下TPI组(n=30)。TAP组和TPI组的平均基线疼痛评分分别为5.5和4.7。在随访第3个月的ITT分析中,组间疼痛评分差异为1.7(95%CI,0.3-3.0),TPI组效果更好。在后续按方案分析中,组间疼痛评分差异为1.8(95%CI,0.4-3.2),TPI组效果更好。在ITT和按方案分析中,组间疼痛评分差异达到了中等效应量。该研究表明与接受TAP阻滞的慢性腹壁疼痛病人相比,接受TPI的病人在随访第3个月时的疼痛评分显著降低。

natural rubber latex is n>the white liquid in the form of the colloidal dispersion of rubber globules suspended in the aqueous liquid. Produced in large quantities in Ivory Coast, the local transformation of natural latex has so far remained insignificant, although some attempts have been made to use it in the manufacture of flexible facade briquettes for rounded walls. Thus, this study aims to incorporate clay as a filler in natural latex for use as an adhesive for tile installation. To do this, different proportions of clay paste were added to the natural latex and the resulting mixtures were used to make the sample and tile adhesive. From the analysis of the results obtained, it appears that the samples with a clay paste density of 0.8 and 1 absorb less water and shown>s good pull-out strength. The mixtures of 30% and 35% latex and 0.8 and 1 clay paste density respectively have pullout stresses greater than 1 N/mm2. According ton>n style="font-family:Verdana;"> nF En 1348, these adhesives can therefore be used as tile adhesive.

The formation and evolution of cosmic string wakes in the framework of a f(R) theory of gravity are investigated in this work. We consider a simple model in which baryonic matter flows past a cosmic string. We treat this problem in the Zel’dovich approximation. We compare our results with previous results obtained in the context of General Relativity and Scalar-Theories of Gravity.
