中枢神经系统白血病血清神经元特异性烯醇酶测定的临床意义

目的 探讨血清神经元特异性烯醇酶与中枢神经系统白血病之间的关系。方法 对确诊的30例急性白血病患者及匹配的正常人的血清神经元特异性烯醇酶进行测定。结果 中枢神经系统白血病组血清神经元特异性烯醇酶含量21．92 7．5μg/L均明显高于白血病组、对照组，差异有显著性。结论 血清神经元特异性烯醇酶可作为反映中枢神经系统白血病病情的生化指标。     

病理性近视眼的研究进展

通过复习近年来相关文献,对近视眼发生发展机制与形觉剥夺之间的关系进行综合评述。认为近视眼的发生及眼轴延长与形觉剥夺有一定关系,深入研究其相关机制,对近视眼的早期防治具有重要意义。     

内脏高敏感与功能性胃肠病

功能性胃肠病(functional gastrointestinal disorders,FGIDs)是指一组以慢性或反复发作的消化道症状就诊,但无明确胃肠黏膜结构改变或生化异常可查的症候群。心理、社会因素可加重FGIDs患者症状,患者可同时伴有躯体症状[1]。其发病机制目前尚不明确,最初该类疾病被认为是胃肠神经官能症,大量的流行病学资料表明,尽管精神压力与患者症状发作有关,但主要还是决定于患者的就医行为。此后,FGIDs发病机制的研究又集中在胃肠动力改变方面,肠易激综合征患者(IBS)、功能性消化不良患者(FD)、非心源性胸痛患者(NCCP)均发现了各种胃肠动力异…     

Gunshot injury of the spinal cord

108 pigs were shot at the level of lumbar 1 to investigate the changes of spinal cord in relation to the speed of shooting and the trajectory through which the bullet passed. The cord lesions of the specimens could be divided, according to its severity, into 4 grades: (1) transection in 41; (2) complete destruction in 43; both lesion 1&2 resulted in permanent paraplegia; (3) incomplete destruction in 13, those resulted in incomplete paraplegia eventually recovered; (4) mild damage, that was concussion in 11, resumed perfectly. Through a transducer sealed into the spinal canal, the intracanal pressure was recorded: (1) Shooting through spinal canal with a pressure over 5 kg caused cord transection. (2) shooting through canal wall with a pressure of 2.5 to 5; 0 kg caused complete cord destruction. (3) shooting nearby the outer margin of vertebra with a pressure less than 1.0 kg caused mild cord damage. It was found that the speed of bullet, the trajectory with relation to cord and the grade of cord lesion are in agreement with each other. The mutual effects among them would make one think it reasonable to classify cord injury as follows: 1. Injury from bullet through spinal canal or vertebral body usually causes cord transaction; 2. Injury from bullet through canal wall at high speed would make a chance of complete destruction in 94%; at low speed, a chance of either complete or incomplete lesion in 50% each. 3. Injury nearby vertebra, high speed bullet would cause a chance of complete cord lesion in 86%; low speed one would make a chance of incomplete lesion in 1/3 and mild lesion in 2/3.     

Effect of Salvia miltiorrhiza on the left ventricular diastolic function in coronary artery stenosis

In 24 open-chest mongrel dogs, coronary artery critical stenosis were produced by a micrometer constriction on left circumflex coronary artery. It was reduction about 87% in lumen area. CBF, -Vce, -dp/dt max were decreased, T was increased (P less than 0.01). 15 minutes after stenosis, the Salvia miltiorrhiza injection was injected into left atrium. CBF, -dp/dt max, -Vce were increased and T was decreased after the injection of Salvia miltiorrhiza. Moreover, the change of CBF was the earliest. The results proved that the Salvia miltiorrhiza could improve the left ventricular diastolic function in coronary artery stenosis.     

Diagnosis and management of obstetric acute disseminated intravascular coagulation]

Twenty-seven in-patients with obstetric DIC in our hospital from Jan. 1971 to Dec. 1990 were analysed retrospectively. The incidence was 0.12% in the first decade and 0.02%, in the second, showing a difference of significance between them. The most common predisposing factors included amniotic fluid embolism, abruptio placenta and hemorrhagic shock. Bleeding from multi-organs in various extent and coagulation disorders occurred in all those 27 cases. [Besides anti-shock treatment, heparin was employed together with fibrinogen in 4 postpartum and 1 antepartum DIC patients, fibrinogen alone in 8 cases, and hysterectomy in 11 cases. 17 patients were saved and 9 died. It is important that early diagnosis and much attention paid to clinical characteristics together with serial laboratory tests. Key management should include prompt treatment and eradication of predisposing factors. Quick decision spite of to terminate the pregnancy and even hysterectomy should be done in some risks.     

APPLICATION OF ACUPOINT-INJECTION THERAPY TO PAIN SYNDROME: CLINICAL ANALYSIS OF 250 CASES

In this paper,250 cases of headache,shoulder pain,lumbago and leg pain weretreated with 20％Angelicae Sinensis mixed with Vitamine B_(12) point-injection therapy.The total effective rate was 95.2％and in which the cure rate was 53.6％.Authors have found a close correlation between the effectiveness and the duration of disease.
