Response of Two Jerusalem Artichoke (Helianthus tuberosus)Cultivars Differing in Tolerance to Salt Treatment

To explore genetic variability for two Jerusalem artichoke (Helianthus tuberosus) cultivars, N1 (the sixth-generation cultivated with 75% seawater irrigation for six years) and N7 (a general variety), a experiment was conducted to study the changes in physiological attributes under different concentrations (0%, 10% and 25% of seawater concentration in greenhouse and 0%, 30% and 50% of seawater concentration in the field) of seawater salinity stress. In the greenhouse experiment, decreases of dry growth rate, but increases of dry matter percentage and membrane injury occurred in both the genotypes at 10% and 25% seawater treatments, although lesser cell membrane damage was observed in N1 than N7. N1 accumulated greater contents of Na+, Cl-, soluble sugar and proline in leaves compared with N7. In the field experiment, the yields of shoot, root and tuber, and the contents of total-sugar and inulin in tubers of N1 were higher than those of N7. Lesser degree of salt injury in N1 indicated that the relatively salt-tolerant cultivar had higher K+/Na+ ratio, lower Na+/Ca2+ ratio, and the salt-induced enhancement of osmotic adjustment.

刺络拔罐结合针刺治疗肝经郁热型带状疱疹的临床效果

目的:探讨肝经郁热型带状疱疹患者经刺络拔罐结合针刺治疗的临床效果。方法:选取2020年1-6月东莞市黄江医院收治的肝经郁热型带状疱疹患者62例为观察对象,根据随机数字表法分为对照组与研究组,各31例。对照组给予对症治疗,研究组在对照组基础上给予针刺综合疗法治疗。比较两组患者临床疗效、疼痛缓解程度、疱疹消退时间、不良反应发生率、后遗症发生率。结果:研究组临床治疗总有效率高于对照组,差异有统计学意义(P=0.024);研究组视觉模拟评分法评分低于对照组,疱疹消退时间短于对照组,差异有统计学意义(P=0.001);随访30 d,研究组后遗神经痛发生率低于对照组,差异有统计学意义(P=0.025)。结论:刺络拔罐结合针刺治疗肝经郁热型带状疱疹患者效果较好,可促进患者症状恢复,缓解疼痛,安全性较高。
