目的:分析单孔法电视辅助胸腔镜(un.portal video-assisted thoracoscopic surgery,UVTAS)肺叶切除术对肺结核患者免疫细胞水平、视觉模拟评分法(VAS)评分及并发症的影响。方法:选取2020年1月—2022年1月在内蒙古自治区第四医院接受UVTAS肺叶切除术的100例肺结核患者,随机分为对照组(n.50)和研究组(n.50)。对照组接受双操作孔胸腔镜手术,研究组接受UVTAS肺叶切除术。比较两组免疫细胞水平、VAS评分及并发症的变化。结果:两组免疫细胞水平时间、组间、交互效应比较,差异均有统计学意义(P0.05)。术后1周,两组VAS评分均比术后1 d低(P<0.05),且研究组更低(P<0.05)。研究组的术后并发症发生率显著低于对照组(P<0.05)。结论:UVTAS肺叶切除术能够提高肺结核患者的免疫功能,减轻术后疼痛及并发症。

Moho depth an. crustal average Poisson.s ratio for 823 station. are obtain.d by H-n. stackin. of receiver fun.tion.. These, to- gether with topography an. receiver fun.tion.amplitude in.ormation. were used to study the crustal structure ben.ath the n.rth Chin. Craton.（n.C）. The results suggest that modified an. preserved crust coexist ben.ath the craton.with gen.rally Airy-type isostatic equilibrium. The equilibrium is relatively low in.the eastern.n.C an. some local areas in.the cen.ral an. western.n.C, which correlates well with region.l geology an. tecton.c features. Major differen.es in.the crust were observed ben.ath the eastern. cen.ral, an. western.n.C, with average Moho depths of 33, 37, an. 42 km an. average Poisson.s ratios of 0.268, 0.267 an. 0.264, respectively. Abn.rmal Moho depths an. Poisson.s ratios are main.y presen. in.the rift zon.s, the n.rthern.an. southern.edges of the cen.ral n.C, an. tecton.c boun.aries. The crust ben.ath Ordos retain. the characteristics of typical craton. Poisson.s ratio in.reases roughly lin.arly as Moho depth decreases in.all three parts of the n.C with differen. slopes. Receiver fun.tion.amplitudes are relatively large in.the n.rthern.edge of the eastern.an. cen.ral n.C, an. small in.an. n.ar the rifts. The Yan.han.Moun.ain. an. southern.part of the Shan.i rift show small-scale variation. in.the receiver-fun.tion.ampli- tudes. These observation. suggest that overall modification.an. thin.in. in.the crust occurred in.the eastern.n.C, an. local crustal modification.occurred in.the cen.ral an. westem n.C. Differen. crustal structures in.the eastern. cen.ral, an. western.n.C suggest differen. modification.processes an. mechan.sms. The overall destruction.of the crustal structure in.the eastern.n.C is probably due to the westward subduction.of the Pacific Plate durin. the Meso-Cen.zoic time; the local modification. of the crust in.the cen.ral an. western.n.C may be due to repeated reactivation. at zon.s with a heterogen.ous s

目的粉防己的主要活性成分为粉防己碱和防己诺林碱,为获得一种快速从粉防己中分离制备粉防己碱和防己诺林碱的方法。方法采用不同溶剂体系萃取测试粉防己中粉防己碱和防己诺林碱在上、下相的分配系数,得到最佳溶剂体系,利用高速逆流色谱(High-Speed Coun.ercurren. Chromatography,HSCCC)对两种生物碱进行制备,并测试纯度。结果经优化得到正己烷-乙酸乙酯-甲醇-水-三乙胺(7∶3∶5∶4∶1)的溶剂体系能够满足实验要求,以该体系上相为固定相,下相为流动相,3 mL·min.(-1)流速进行HSCCC分离,能够在70 min.连续分离得到防己诺林碱(F1)和粉防己碱(F2),经HPLC测试纯度分别为97%和95%。结论通过HSCCC快速制备获得高纯度粉防己碱和防己诺林碱,较现有柱色谱和pH梯度逆流色谱等方法节省大量时间。
