山东省烟台地区发热伴血小板减少综合征疑似病例检测分析

目的 调查山东省烟台地区发热伴血小板减少综合征疑似病例新型布尼亚病毒(SFTSV)感染情况。 方法 采用双重探针引物实时荧光定量-聚合酶链反应方法对发热伴血小板减少综合征疑似病例血清进行新型布尼亚病毒特异性核酸检测。 结果 135份疑似病例血清样本中新型布尼亚病毒特异性核酸阳性81份,阳性率60.00%。发病第5～8天核酸检出阳性最高;发病高峰主要集中在5-8月;人群年龄分布在37～87岁之间,以60～70岁年龄组发病数最多,占总病例数的32.10%(26/81);92.59%(75/81)的患者为农民;男女性别比为1.79:1。 结论 烟台地区发热伴血小板减少综合征疑似病例存在新型布尼亚病毒感染。     

NONSPECIFIC THYROIDITIS

A clinical and pathological study was made on 53 cases of nonspecific thyroiditis operated on from 1962 through 1982. These included 36 Hashi. moto's disease, 7 Riedel's disease and 10 giant cell thyroiditis. There was no operative mortality or serious complication. With Hashimoto's disease, postoperative hypothyroidism occurred in 23 patients (63.9%) and the degree of lymphocytic infiltration of the thyroid appeared to be a more important factor relating to the occurrence of postoperative hypothyroidism rather than the amount of thyroid tissue resected. In mild Iymphocytic infiltration hypothyroidism did not appear when resection was limited to less than 50%. Therefore, intraoperative frozen section biopsy is beneficial not only for diagnosis but also for the choice of a proper opera- tive procedure. An association of Hashimoto's disease with hyperthyroidism was found in 10 cases. There were 3 clinical types of such association: Symptoms of hyperthyroidism preceded thyroiditis; thyroiditis occurred first and then the symptoms of hyperthyroidism; and both disorders occurred simul- taneously. As thyroiditis is generally considered an autoimmune disease, whether these three clinical types are different stages of the autoimmune reaction needs further investigation.

肾开放性手术中单根导管双向引流的应用

目的总结单根导管双向引流在肾开放性手术中治疗复杂肾结石的应用经验。方法回顾性分析158例复杂肾结石患者在肾开放性手术中应用单根导管双向引流的临床资料，手术中均行肾盂、肾实质切开取石并置单根导管双向引流。结果158例患者手术切口无一例感染和尿瘘形成。结论肾开放性手术治疗复杂肾结石后单根导管双向引流可缩短漏尿时间，有效防止切口感染、尿瘘形成及其他置管方法引起的并发症，方法简单，便于掌握。     

太阳光对紫外线监测结果的影响

紫外线用于空气及物体表面的消毒，主要是通过灯管辐射出具有一定强度的紫外线光波被空气中的微生物吸收而达到杀菌目的的。在使用过程中其辐射强度会逐渐降低，如小于70uw／cm2则达不到消毒目的。为保证消毒效果，定期对使用中的紫外线辐射强度进行监测是院感管理的一个重要环节。我们在监测过程中发现紫外线灯在向一时间、同一地点、相同温湿度、有太阳光和无太阳光照射情况下所测结果差别很大，说明太阳光对监测仪所显示的辐射强度有一定影响。本组在本院共选择厂16只紫外线灯管在以下条件下进行计比监测。1监测仪器与材料1．五仪器ZDZ…

莱姆（Lyme）病的神经系统表现：附2例报告

莱姆病(Lyme disease)是由伯氏疏螺旋体(Borrelia burgdorferi)引起的一种蜱媒螺旋体病。此病是一种多系统受损害的综合征,除了出现皮肤慢性游走性红斑(ECM)、心脏损害、关节炎症外,还可出现复杂的神经系统症状。为引起临床重视,报告2例并结合文献对本病的神经系统表现做一简要讨论。例1,男,56岁,于1990年5月初,在黑龙江省富锦县一江边,左腋下被蜱叮咬,被蜱     

A COMPARATXVE STUDY OF LONG-TERM RESULTS OF SPLENORENAL SHUNT AND MEDICALTEREATMENT FOR lNTRAFIEPATIC PORTAL HYPERTENSXON AN ANALYSIS OF 258 CASES

The Iong-term results of 25S cases of in- trahepatic portal h3-pertensiw treated eit;her surgically (splenorenal shunts) or mcdically in this hospital during 19s3-197s are analyz.ed. The 5-year, 10-year, la-year and 20-ycar absolute survival rat.es of the l-1-0 surgical ca.ses and the 118 medical cases were respectively as follows: (i7.8% and;21.3% 52.0% and 7.7%; 50.O% and 2.5% and 30.O% and O%. The results in the medical group arc poorer even ii Child's C patients were exclutled. Patients trea.ted by splenorenal shunts have a ruuch more tavoraWe prognosis than those treated medically.
