Short latency somatosensory evoked potentials and brainstem auditory evoked potentials in patients with head trauma

The SSEPs in 115 patients with head trauma were analysed by NT+ W value, da, db and b/a methods. The results revealed that the abnormal rates of the SSEPs were 94.8%. The pathological bases resulting in it were the direct and/or indirect lesion on the somatosensory pathway. The SSEPs recorded six months after the trauma indicated that the electric activities of neurons in some of the patients were still abnormal although they recovered well. The patients complicated with traumatic lesion of acoustic nerve, blood clots in external ear canal and pre-existing hearing loss had abnormal BAEPs that could not be used in diagnosing brainstem lesion. The patients without these complications in whom BAEPs were abnormal had an unfavourable outcome. The SSEPs and BAEPs simultaneously recorded could aid localization of the injury in the brain and enable discovery of the fact that the rigidity after decortication or decerebration is a result of severe injury of the cerebral hemisphere.     

人群中病毒性肝炎的型别研究

作者于1987年2月16日～1988年2月15日在四川五个点211 639人群中监测急性病毒性肝炎。其发病率为167.74/10万,其中甲型肝炎占24.51％;乙型肝炎占38.31％;非甲非乙型肝炎占24.51％,EB病毒和巨细胞病毒所致肝炎各占3.38％;混合感染占5.92％。病毒性肝炎中有14.93％重叠感染。发病高峰在春季。发病率,男:女=1.75:1。甲型肝炎20岁以下年龄组、乙型肝炎20～39岁年龄组的发病率明显高于其他年龄组,非甲非乙型较分散,5～19岁相对多一些,其他型别年龄组间无明显差异。355例急性病毒性肝炎患者中43.9％有接触史,36.6％有注射史。     

新生儿紫绀型先天性心脏病的特点(附5例临床与病理资料分析)

5例新生儿于出生时,生后2小时、4小时、7天起病。表现为紫绀、缺氧发作、呼吸困难及心力衰竭。生后2～7天检查心电图、胸片及超声心动图,分别提供相应的病征。早者于4天、晚者于半月死亡。死后均经病理证实为新生儿严重的紫绀型先天性心血管畸形。本文结合临床与病理资料讨论新生儿紫绀型先天性心脏病特点及血液动力学改变。     

慢性丙型肝炎患者丙型肝炎病毒核酸与IgM抗体关系的研究

本文检测了１４０例丙型肝炎病毒（ＨＣＶ）抗体（抗－ＨＣＶ）阳性的慢性丙型肝炎（ＣＨＣ）的ＨＣＶ核酸（ＨＣＶＲＮＡ）和ＩｇＭ抗体（抗－ＨＣＶＩｇＭ）两项指标。结果表明，原始诊断为不同临床型的肝炎（ＨＣ）患者，８年随访时，ＨＣＶＲＮＡ和抗－ＨＣＶＩｇＭ阳性率分别为８０．７％和９０．７％（ｕ＝２．３９Ｐ＜０．０５）．在原始诊断不同临床型ＨＣ转慢者中，上述两项指标均未发现统计学上的差别（均为Ｐ＞０．０５）。ＨＣＶＲＮＡ与抗－ＨＣＶＩｇＭ配对比较，符合率为７８．６％。基因分型初步结果表明，河北省固安ＨＣＶ以基因Ⅱ型为主。本研究提示，随访８年的ＣＨＣ患者绝大多数仍有传染性；本文方法检测的抗－ＨＣＶＩｇＭ不能代表早期感染标志，但代表慢性感染活动化或带毒，所以，在不具备检测ＨＣＶＲＮＡ的地方更具有实用价值．     

血浆成分分离治疗类风湿性关节炎21例

１９９２年１０月以来，对２１例类风湿性关节炎共进行了７１人次血浆成分分离治疗（ＰＦ），平均１－２周内进行３．６人次，并在治疗前后进行总体评估。结果示：疗程完成后，全部病例的体力活动和实验室指标均有不同程度改善，３例活动受限者治疗后均能自由行走。平均每次分离血浆５７３１±１２９ｍｌ，其中ＩＣ，ＩｇＧ，ＩｇＧ，ＩｇＡ，均有统计学意义的减少。血沉从８０．２１±３４．００ｍｍ／ｈ降到５１．４０±３１．２８ｍｍ／ｈ，８例类风湿因于阳性的患者中，５例阴转，作者认为ＰＦ正在成为一种实用的技术，并可能是治疗类风湿关节炎最好的方法之一。     

Enema reduction of intussusception by hydrostatic pressure under ultrasound guidance: a report of 377 cases

Three hundred seventy-seven pediatric intussusception patients were treated by normal saline hydrostatic enema under ultrasound guidance from October 1985 to April 1987. Before reduction, the rate of correct diagnosis by ultrasonography was 100%, and the rate of successful reduction was 95.5% in this group. With this technique there is no risk of x-ray exposure to the patient. The definite criteria for reduction are discussed. Clear echogram was shown during reduction and the ileo-ileo-coli intussusception can be diagnosed. Intestinal perforation, if any, can be accurately recognized at once. This technique is believed to be one of the most promising methods in nonoperative treatment of pediatric intussusception.     

哒嗪酮酸类化合物的合成及其抗惊活性的研究

以ａ－酮戊二酸与水合肼与水合肼为原始原料合成了１５个Ｎ－（３’－磷酸二乙酯丙基）－１，６－二氢－６－氧－３－哒嗪酰胺类化合物，并对它们进行了最大电休克发作（ＭＥＳ）实验，结果表明其中４个化合物表现出中等强度的抗惊活性。     

强噪声对大鼠血液粘度血糖及几种酶的影响

本文检测强噪声刺激12小时大鼠血液流变学九项指标,胆碱酯酶和谷丙转氨酶活力及血糖浓度,与对照组比较,其结果显示:(1)低切粘度,红细胞电泳时间和全血还原粘度明显增高(P<0.05;P<0.05和P<0.01);(2)真性和假性胆碱酯酶活力明显增高(二者均P<0.01);(3)血清谷丙转氨酶活力和血清葡萄糖浓度显著增高(P<0.01和P<0.05)。揭示强噪声作用后机体听觉外系统发生明显变化,长期暴露后必将严重损伤全身性调节功能而引起脏器损害与疾病。     

脊神经节神经元周围突至肾及体壁的分支投射

实验将快蓝(FB)和核黄(NY)分别注入大鼠左肾纤维膜下及左体壁神经干内,结果在荧光镜下发现左T_(9-13),L1脊神经后根节(DRG)内存在双标记细胞,提示大鼠T_(9-13),L1段DRG内的部分神经元的周围突分支支配肾及体壁,为肾绞痛所致牵涉痛的解释,提供了神经解剖学基础。
