中青年脑梗死68例临床分析

脑梗死多见于老年人，但近年来中青年（16-45岁）患者逐渐增多且有年轻化趋势，深人探讨中青年脑梗死的致病因素及临床表现对其防治有重要意义。本文回顾性分析了我院自1998年1月到2004年12月问收治的中青年脑梗死患者68例，现报告如下。     

Do children with primary nocturnal enuresis have a retarded bone age? A cross‐sectional study

OBJECTIVE: Nocturnal enuresis is a common pediatric problem, the etiology of which is unclear. In recent years, various studies have been published stating that children with nocturnal enuresis exhibit growth and skeletal maturation retardation. METHODS: In this cross-sectional study, we included 27 patients (16 boys, 11 girls) between the ages of 6 and 14 years who had presented with primary nocturnal enuresis (PNE) complaints. We included in the evaluation 19 healthy subjects (12 boys, 7 girls), who were the siblings of the children with PNE, as the control group. RESULTS: The patients in both groups were similar in chronological age, bone age, height and weight, with no significant difference between groups (P>0.05). CONCLUSION: The two groups in our study consisted of the same genetic background. Thus, our results were found to be different from the previous studies. We have concluded that there is no direct relationship between enuresis nocturnal and skeletal maturation.     

胎儿生长迟缓与新生儿胰岛素敏感性变化的相关性

目的探讨胎儿生长迟缓(FGR)与新生儿胰岛素敏感性变化的关系。 方法昆明医学院第一附属医院于2004年4~12月，对72例小于胎龄儿(SGA)和48例适于胎龄儿(AGA)空腹血糖(FPG)、空腹胰岛素(FINS)、C 肽、HDL C、LDL C、TG、非酯化脂肪酸(NEFA)等指标，计算葡萄糖/胰岛素比值(G/I)、胰岛素敏感性指数(ISI)、胰岛素抵抗指数(HOMA IR)、胰岛β细胞功能(HBCI)等，探讨FGR与新生儿胰岛素敏感性变化的关系。 结果(1)SGA组FPG、HDL C低于AGA组，而FINS、LDL C、TG、NEFA高于AGA组(P<001)；(2)SGA组G/I比值、ISI低于AGA组，HOMA IR高于AGA组(P<001)，而HBCI两组相比差异无显著性(P>005)。 结论FGR儿在生命早期存在胰岛素敏感性降低和不同程度的胰岛素抵抗(IR)，而胰岛β细胞功能无明显变化。     

2 121例老年急性冠脉综合征患者血清脂类浓度的分析

目的分析60岁以上老年人血清脂类水平的参考值,并探讨急性冠脉综合征与血脂指标的相关性.方法将3 766例健康成人分为≤60岁和＞60岁的两个年龄段,采用生物化学的方法测量他们的血脂水平,找出60岁以上老年人的脂类参考值.同时分析2 121例老年急性冠脉综合征病人的脂类指标.结果 60岁以上老年人血脂参考值为:TC 4.65±1.96×1.05mmol/L;TG 1.02±1.96×0.45mmol/L;HDL-C 1.47±1.96×0.40mmol/L;LDL-C 2.98±1.96×0.56mmol/L;ApoA1 1.32±1.96×0.25g/L;ApoB 0.99±1.96×0.35g/L,并且急性心肌梗死和不稳定性心绞痛病人血清脂类各项指标之间没有显著性差异.结论血清LDL-C/HDL-C＞5和TG ≥1.9mmol/L这两项联合指标比其他单独指标与老年人急性冠脉综合征关系更密切.     

Does the Extent of Surgery Make a Difference in High Grade Malignant Astrocytoma?

This paper examines the effect of patient age, tumour grade and extent of surgery on the outcome of treatment of 278 patients with high grade malignant gliomas referred to the Queensland Radium Institute between 1980 and 1987. The aim was to determine whether the extent of surgical resection alters survival rates. The extent of surgery had no effect on survival except for those patients with grade 3 tumours in whom a total excision was possible. Those in whom only a biopsy was done did not have a worse prognosis. Grading was found to be of importance, as patients with grade 3 tumours had a better survival than those with grade 4 tumours. In grade 4 tumours, those under 30 years of age had a better survival than those over 30 years, whereas with grade 3 tumours there was a gradation of age effect (under 40 years best, then 40–49 years, and those 50 years and over doing worst).     

Older donors and kidney transplantation

Reluctance to use kidneys from older donors (>50 years of age) is based on reports of inferior results. We reviewed our experience with 45 kidneys transplanted from older donors. Primary nonfunction, immediate graft function, and 1-, 2- and 3-year graft survival rates were similar to those obtained with kidneys transplanted from donors aged between 20 and 40 years. Renal function at 1 year (as measured by serum creatinine) was poorer in kidneys from older donors. No beneficial effect with respect to graft survival was noted with cyclosporin therapy compared to conventional immunosuppression; however, the numbers are small. We conclude that kidneys from older donors are a valuable source for transplantation.     

Angiodysplasia as the cause of massive lower gastrointestinal hemorrhage in a young adult

PURPOSE: This study was undertaken to clarify the importance of bleeding vascular ectasia of the colon as the etiology of massive lower gastrointestinal hemorrhage in patients 40 years of age or younger. METHODS: An otherwise healthy 21-year-old male was admitted to a tertiary medical center with massive lower gastrointestinal hemorrhage. Technetium-labeled red blood cell scan, selective visceral angiography, and colonoscopy identified the source of bleeding as vascular abnormality of the descending colon. Segmental colonic resection was performed. RESULTS: Histologic review of the specimen demonstrated a vascular ectasia. The patient recovered uneventfully and has had no further stigmata of hemorrhage. A review of the literature was undertaken to make clear the significance of vascular ectasia as the source for massive colonic hemorrhage in the young adult. CONCLUSION: This is the first report that documents histologically a vascular ectasia as the source of massive lower gastrointestinal hemorrhage in an otherwise healthy patient less than 40 years of age. Vascular ectasia is an uncommon cause of lower gastrointestinal hemorrhage in the young adult.The Chief, Bureau of Medicine and Surgery, Navy Department, Washington, DC, Clinical Investigation Program sponsored this report #84-16-1968-532, as required by HSETCINST 6000.41A.

[1]目的 了解枢椎形态和结构的性别和地区差异.[2]方法 对通辽与长春两地区129套成人枢椎(男76套,女53套)进行了测量,指标包括齿突高、全高、椎体高、矢径、全宽、椎孔矢径和椎孔横径,并计算了椎体指数和椎孔指数.对所得数据进行统计学处理.[3]结果 枢椎的7项测量指标,除椎孔矢径与横径(长春地区的椎孔横径除外)以及通辽地区齿突高外,其性别差异均具极显著性(t＝2.34~7.68,p<0.01或0.05);两地区比较,除女性齿突高外,其他指标差异均无显著性(t＝0.03~1.95,p均>0.05).指数比较,除两地区女性椎体指数外,均无性别和地区间差异(t＝0.04~1.86,p均>0.05).[4]结论 通辽和长春两地区成人枢椎的形态和结构无明显差异.     

80例健康青年分别经针刺或艾灸肺俞穴后的肺功能变化

目的：探讨针刺与艾灸肺俞穴对健康人肺功能的影响。方法：我们选择了20－22岁健康男性80例，随机分为针刺组和艾灸组各40例，于针刺，艾灸前和针刺，艾灸后10min测试用力肺活量（FVC），用力呼气量（FEV1．0），最大呼气中段流速（MMF），最大呼气流量（PEFR），75％，50％，25％肺活量时的最大呼气流速（V75，V50，V25），结果：显示经针刺和艾灸肺俞穴后2组FVC，FFV1．0均显著增加，P＜0．05，2组间比较针刺组FVC明显高于艾灸组，P＜0．05，而且艾灸组MMF，V25亦显著降低P＜0．05，结论：健康人经针刺和艾灸肺俞穴后均可使大气道阻力减少，肺容量增加，提示一定量的艾燃烧后的烟雾可使健康人肺功能受到影响，使肺的小气道收缩，出现阻塞性改变。
