作者： Zhao Yingjie wen zhaoming Bai Xianli Liu Shishi Tea Sciences and Research Institute of Guilin

A systematic investigation on spiders in a tea garden of Guilin Institute of Tea Sciences was conducted. The results showed that totally 687 specimens were collected, belonging to 34 species, 27genera, 14 families, 2 suborders, and a new record species Trochosa suiningensis in Guangxi was found. Spider is a ma- jor developing natural enemy group of insect pests in tea garden, with features of wide distribution, large quantity, long duration, strong predatory and stress resist- ance, which has strong predation on adults and nymphs of Empoasca vitis and young larvae of Ectropis oblique. The population of spiders in tea garden significantly increases after middle June, and reaches the peak in July and August every year.

目的探索皮下免疫治疗（SCIT）产生全身反应的危险因素及相应对策.方法对1993年12月至2013年9月在北京协和医院变态反应科就诊的接受变应原SCIT的患者进行回顾性调查,主动询问全身反应的发生情况,得到肯定答复后,作为本组观察对象,共35例.仔细询问和记录反应发生的全过程,并探寻其危险因素,调整治疗方案后继续SCIT并进行长期随访观察.结果 35例SCIT患者共发生全身反应70次,97.1％（68/70）发生于过敏原最高浓度（10-2）注射期间.在所有危险因素中,过敏原最大剂量（指10-2浓度0.6～1.0 ml）占27.2％（28/103）、致敏花粉季节继续较大剂量（未减量）注射占20.4％（21/103）、存在大局部反应时仍继续加量注射占12.6％（13/103）、疑注射操作有误占12.6％（13/103）、误注致增量幅度较大占9.7％（10/103）等.除6例因个人原因以及暂不宜继续进行SCIT者外,其余29例在采取了相应措施（包括不再进行最大剂量注射、于致敏花粉季节停止注射高浓度过敏原、存在大局部反应时减量、要求注射在医疗机构进行、制订规范化注射操作规程等）后,继续治疗未再出现全身反应.结论对SCIT全身反应危险因素的探寻,并采取相应措施,可减少其发生.这为今后SCIT预防和减少全身反应的发生提供了经验和教训.
