目的：观察瑶药膏联合瑶药罐治疗脑卒中后肩手综合征（SHS）的临床疗效。方法:将80 例脑卒中后SHS患者随机分为治疗组和对照组,每组各40 例。对照组予以西医康复治疗,治疗组在对照组的基础上加用瑶药膏合瑶药罐治疗。治疗4周后,观察比较2组综合疗效及治疗前后的视觉模拟评分法（VAS）评分、Fugl-Meyer运动功能（FMA）评分、水肿程度、改良Barthel指数（MBI）评分。结果：总有效率治疗组为95.00%（38/40）,对照组为80.00%（32/40）,2组比较,差异有统计学意义（P＜0.05）。治疗后,2组VAS、FMA评分,水肿程度以及MBI评分均明显改善,且治疗组改善幅度更为明显,两两比较,差异均有统计学意义（P<0.01或P<0.05）。结论：瑶药膏联合瑶药罐治疗脑卒中后SHS疗效颇佳,可明显缓解疼痛,减轻水肿,改善肢体功能,提升生活质量。 相似文献

The effect of water temperature on gut mass and digestive enzyme activity in sea cucumber Apostichopus japonicus, including relative gut mass (RGM), amylase, lipase, pepsin and trypsin activities were studied at temperatures of 7, 14,
21, and 28°C over a period of 40 days. Results show that RGM significantly decreased after 40 days at 21°C and markedly decreased
over the whole experiment period at 28°C; however, no significant effect of duration was observed at 7 or 14°C. At 14°C, trypsin
activity significantly decreased over 10 and 20 days, then increased; amylase and trypsin activity significantly decreased
after 40 days at 28°C. However, no significant effect of duration was found on amylase, pepsin or trypsin activities in the
other temperature treatment groups. At 28°C, lipase activity peaked in 20 days and then markedly decreased to a minimum at
the end of the experiment. On the other hand, pepsin activity at 28°C continuously increased over the whole experimental period.
Principle component analysis showed that sea cucumbers on day 40 in the 21°C group and in the previous 20 days in the 28°C
group were in the prophase of aestivation. At 28°C, sea cucumbers aestivated at 30–40 days after the start of the experiment.
It is concluded that the effect of temperature on the digestion of A. japonicus is comparatively weak within a specific range of water temperatures and aestivation behavior is accompanied by significant
changes in RGM and digestive enzyme activities. 相似文献

The influence of Bacillus probiotics on the digestive enzyme activity and the growth of Litopenaeus vannamei were de-termined in this study. The shrimp was treated with five percentages (1.5, 3.0, 4.5, 6.0 and 7.5) of probiotics (Bacillus spp.) supple-mented to the feed and cultured for 45d. The growth measured as the weight gain at the end of culturing was significantly (P<0.05) higher in probiotic-treated shrimps than that of the control (without receiving probiotics). Activities of protease and amylase, two digestive enzymes of the midgut gland and the intestine were significantly (P<0.05) higher in probiotic-treated shrimp than in the control. 相似文献
