In this paper, the finger muscular forces were estimated and analyzed through the application of inverse dynamics-based static optimization, and a hand exoskeleton system was designed to pull the fingers and measure the dynamics of the hand. To solve the static optimization, a muscular model of the hand flexors was derived. The experimental protocol was devised to analyze finger flexors in order to evaluate spasticity of the clenched fingers; muscular forces were estimated while the flexed fingers were extended by the exoskeleton with external loads applied. To measure the finger joint angles, the hand exoskeleton system was designed using four-bar linkage structure and potentiometers. In addition, the external loads to the fingertips were generated by cable driven actuators and simultaneously measured by loadcells which were located at each phalanx. The ex- periments were performed with a normal person and the muscular forces estimation results were discussed with reference to the physical phenomena.

目的观察细粒棘球蚴囊液蛋白(hydatid cyst fluid protein,HCFP)对卵清蛋白(ovalbumin,OVA)诱导的小鼠变应性鼻炎(allergic rhinitis,AR)的保护作用。方法将24只BALB/c小鼠(8~10周龄,体质量约20 g)随机分成A(空白对照组)、B(空白干预组)、C(AR模型组)、D(AR+HCFP干预组)4组,每组6只。在基础致敏阶段(实验第0、2、4、6、8、10、12天),A、B、C、D组小鼠分别腹腔注射200μL无菌磷酸盐缓冲液(phosphate buffered saline,PBS),含20μg HCFP的无菌PBS溶液,含50μg OVA和5 mg Al(OH)3凝胶的无菌PBS溶液,含50μg OVA、5 mg Al(OH)3凝胶和20μg HCFP的无菌PBS溶液。在局部激发阶段(实验第14~20天),A、B、C、D组小鼠分别鼻腔滴注体积为40μL的无菌PBS、含20μg HCFP的无菌PBS、含2 mg OVA的无菌PBS、含2 mg OVA和20μL HCFP的无菌PBS。观察各组小鼠行为学改变并进行行为学评分,采用酶联免疫吸附试验(enzyme-linked immunosorbent assay,ELISA)检测各组小鼠血清γ干扰素(interferon-γ,IFN-γ)、白细胞介素4(interleukin-4,IL-4)、IL-5、IL-10、转化生长因子-β(transforming growth factor-β,TGF-β)和OVA特异性IgE抗体(OVA-sIgE)水平,采用苏木精-伊红(HE)染色观察各组小鼠鼻黏膜病理学改变。结果C组小鼠行为学评分[(6.83±0.50)分]显著高于A组[(1.17±0.52)分]和B组[(1.33±0.52)分],D组小鼠行为学评分[(3.50±0.50)分]较C组降低(P均<0.05)。4组小鼠血清IFN-γ(F=4.08,P<0.05)、IL-4(F=275.90,P<0.05)、IL-5(F=96.82,P<0.05)、IL-10(F=77.67,P<0.05)、TGF-β(F=9.98,P<0.05)及OVA-sIgE水平(F=44.69,P<0.05)差异均有统计学意义。C组小鼠血清IFN-γ水平低于A、B组和C组,且血清IL-4、IL-5、OVA-sIgE水平均高于A、B组和C组(P均<0.05);D组小鼠血清IL-10、TGF-β水平高于C组(P均<0.05)。镜下观察显示,C组小鼠鼻黏膜纤毛脱落缺损明显,杯状细胞数量增多且体积增大,间质水肿,黏膜下见小血管扩张;D组小鼠鼻黏膜病变较C组轻。结论HCFP对OVA诱导的小鼠AR具有保护效果。

目的评价止喘灵口服液治疗支气管哮喘的有效性和安全性。方法以纳入的中国12家研究中心共计385例受试者作为研究对象,随机入组353例分为试验组(止喘灵组)、联合治疗组(止喘灵联合沙美特罗丙酸氟替卡松50/100μg吸入)和对照组(沙美特罗丙酸氟替卡松50/100μg吸入),观察各组治疗前后哮喘控制率、哮喘控制测试(ACT)评分、哮喘生命质量表(AQLQ)评分变化值及不良反应发生情况。结果止喘灵组102例,联合治疗组108例,沙美特罗丙酸氟替卡松对照组103例。治疗4周后,3组哮喘控制率分别为91.49%、90.10%和94.79%,止喘灵组不劣于对照组。3组ACT评分较基线变化值分别为(6.49±2.96)分、(7.07±2.75)分和(6.20±2.83)分,组间比较差异无统计学意义(P=0.0545)。3组AQLQ评分变化值分别为(39.30±24.03)分、(42.20±22.70)分和(37.18±26.75)分,组间比较差异无统计学意义(P>0.05),止喘灵组和沙美特罗丙酸氟替卡松对照组均有提高患者生活质量的作用且差异无统计学意义。结论止喘灵口服液可有效治疗支气管哮喘,疗效不差于沙美特罗丙酸氟替卡松粉吸入剂。相比单独用药,联合用药可能在控制哮喘发作、提高患者生活质量、改善临床症状、减少缓解药物用量方面发挥其优势。
