Sliding cupping was applied on the back, followed by moxibustion along the running course of the governor vessel. After 6 treatments, the symptoms and signs of patients were evaluated according to guideline and reported.ResultsCompared with before treatment, the score of symptoms and sighs all decreased after treatment(7.64 ± 1.62 vs 1.86 ± 0.65 ,2.57 ± 1.26 vs 0.96 ± 0.57, both P < 0.05). Among 28 patients, the treatment was remarkably effective in 14 patients, effective in 12 patients and no effect in 2 patients. The total effective rate was 92.86%. No severer adverse events happened during the treatment.ConclusionThe combined treatment of moxibustion along the governor vessel and sliding cupping therapy could be effective for allergic rhinitis, and may require further investigation for its effectiveness.展开更多

Over the long course of evolution, plants have produced many mechanisms to resist this biotic stress such as pigment accumulation. Pigment levels determined depth and distribution of leaf color, thereby indirectly or directly affecting the behavior of insect attack. Therefore, understanding the mechanism of mutual recognition between leaf color and insect will provide important theoretical insight for the cultivation and improvement of new cultivars. This paper outlines leaf-color formation and the effect of pigment on the behavior of insect attack, and explores the challenge of research in the interaction between leaf color and insect, as soon as the potential direction for future development. This will give a broad background for improvements of colored plants with resistance to insect attack.展开更多

文摘背景胃肠神经内分泌肿瘤(gastrointestinal neuroendocrine neoplasms,GI-NENs)临床表现多样,部分具有高侵袭性及转移性,预后差.收集我院诊治的GI-NENs患者的临床病理资料,免疫组化检测CD155、T细胞免疫球蛋白和ITIM结构域蛋白(T cell immunoreceptor with Ig and ITIM domains,TIGIT)的表达量,探讨其与临床病理和预后的关系,为患者的治疗提供一个新的方向.目的探讨CD155、TIGIT在GI-NENs中的表达量与临床病理特征的关系.方法收集2016-11/2020-08经我院诊治的168例GI-NENs患者的临床病理资料.免疫组化检测CD155、TIGIT的表达量,探讨其与临床病理和预后的关系.结果CD155和TIGIT在病理分级高的GI-NENs组织中,表达量也较高,差异有统计学意义(P<0.05);CD155表达量与年龄、肿瘤位置、肿瘤最大直径、病理分级、T分期、淋巴结转移、远处转移、TNM分期、Ki-67指数有关(P<0.05);TIGIT表达量与肿瘤最大直径、病理分级、T分期、淋巴结转移、TNM分期、Ki-67指数有关(P<0.05);CD155和TIGIT表达量高的患者预后较表达量低者差,差异有统计学意义(P<0.05).结论CD155和TIGIT表达量在不同分级、分期的GI-NENs患者存在差异,可能参与了GI-NENs的发生及进展的调控过程,高表达可能提示预后不佳.
