【摘要】 目的 探讨不同年龄段肠系膜淋巴结炎与肺炎支原体的关系与临床意义。方法 分肠系膜淋巴结炎和非肠系膜淋巴结炎两大组，其中肠系膜淋巴结炎和非肠系膜淋巴结炎患儿分别分两小组，1~3岁组、3~14岁组，分别比较同年龄组肠系膜淋巴结炎和非肠系膜淋巴结炎患儿肺炎支原体抗体IGM(MP-IGM)的阳性率以及不同年龄组肠系膜淋巴结炎患儿MP-IGM的阳性率有无统计学差异。结果 1~3岁组肠系膜淋巴结炎患儿与非肠系膜淋巴结炎患儿MP-IGM无统计学差异，3~14岁组肠系膜淋巴结炎患儿与非肠系膜淋巴结炎患儿MP-IG有统计学差异，1~3岁组与3~14岁组肠系膜淋巴结炎患儿MP-IGM有统计学差异。 结论 1~3岁组肠系膜淋巴结炎与MP感染无密切相关性，3~14岁组肠系膜淋巴结炎与MP感染有密切相关性，肠系膜淋巴结炎患儿与MP感染的关系存在年龄差异。

【Abstract】 Objective To analyse therelationshipbetweenmesenteric lymphadenitisof different agein children hospitalizedand MP infectionand guide clinical treatment. Methods The patients were into two groups,includingthe experimental group (1~3 Years old and 3~14 Years old) andthe control group.(1~3 Years old and 3~14 Years old).Firstlycompared positive rate of MP-IGM in the experimental group andthe control groupof differentage.The positive rate between 1~3 Years old and 3~14 Years old were compared in experimental group. Results There was no significant difference of MP-IGM betweenthe experimental group andthe control group of 1~3 Years old and significant difference of 3~14 Years old.There was significant difference of MP-IGM betweenthe 1~3 Years old and3~14 years old in the experimental group.Conclusion There is no close relevance beteween mesenteric lymphadenitis andMP infectionof1~3 Years old children and close relevance of 3~14 Years oldchildren. There issignificant difference of MPinfection beteween 1~3 Years old and 3~14 Years old.

小儿肠系膜淋巴结炎一般认为是由病毒或细菌血行感染所致。现将2006年1月至2011年1月收治的152例肠系膜淋巴结炎和852例非肠系膜淋巴结炎的感染患儿(包括呼吸道和消化道感染)报告如下。
1 资料与方法
1.1 一般资料 肠系膜淋巴结炎患儿(实验组)1~3岁组50例， 3~14岁组102例，非肠系膜淋巴结炎的感染患儿(对照组)1~3岁组524例， 3~14岁组328例。肠系膜淋巴结炎患儿符合肠系膜淋巴结炎诊断标准：①间隙性、痉挛性不定位腹痛病史，有压痛但无反跳痛，多位于脐周及右下腹，应用解痉药不缓解。②超声检查腹腔内可见多发肿大淋巴结，纵横比>2(短轴>0.5 cm)。非肠系膜淋巴结炎的患儿包括除肠系膜淋巴结炎外的呼吸道和消化道感染患儿。
1.2 临床特点 肠系膜淋巴结炎患儿均有阵发性腹痛或哭吵，腹痛呈痉挛性，以脐周及右下腹痛为主；应用解痉药不缓解；有腹痛或哭吵，无反跳痛或反跳痛表情；发病前1 d~4周均有呼吸系统感染征象，可伴呕吐、腹泻。非肠系膜淋巴结炎的患儿临床B超排除肠系膜淋巴结炎，可有咳嗽、流涕、气喘、发热、呕吐或腹泻等表现。
1.3 实验室检查 检查血清Mp-IgM滴度；超声检查腹腔内可见多发肿大淋巴结为肠系膜淋巴结炎组。
1.4 统计学方法 采用SPSS 11.5软件包对数据进行统计学分析，计数资料采用χ�2检验，P 3~14岁组465610245.0
合计5210015234.2
