一种防脱出易制作义眼台的研制

目的探讨一种新型简易防脱出的义眼台的制作方法与效果。方法根据眼球摘除后的解剖特点设计义眼台大小,选择聚甲基丙烯酸甲酯和涤纶布为材料制作复合材料义眼台,并对6只家兔行眼球摘除后置入义眼台,经HE染色观察及肉眼观察术后不同时间置入物与眼周围组织的解剖关系。结果聚甲基丙烯酸甲酯部分与组织无黏连,涤纶布形成牢固黏连,周围有纤维组织长入并包绕,义眼台无脱出、移位。结论以聚甲基丙烯酸甲酯和涤纶布为材料制作复合义眼台,方法简易,效果可靠,组织相容性好,术后反应轻,值得在临床上推广使用。     

甲状旁腺腺瘤伴甲状腺腺瘤99Tcm-MIBI显像一例

^99Tc^m-甲氧基异丁基异腈（MIBI）甲状旁腺平面显像诊断甲状旁腺腺瘤有2种阳性显像图，即甲状腺下缘型——单侧甲状腺下极外见浓聚灶和甲状腺腺体型——一侧甲状腺腺内见放射性浓聚灶，前者多见，后者少见。^99Tc^m-MIBI是一种亲肿瘤显像剂，可被甲状旁腺腺瘤和甲状腺腺瘤摄取。因此，鉴别甲状腺腺体型的甲状旁腺腺瘤与甲状腺腺瘤是避免误诊的关键。笔者报道一例罕见甲状旁腺腺瘤伴甲状腺腺瘤的^99Tc^m-MIBI显像结果，供读者参考。

国产医用聚丙烯酰胺水凝胶对动物内脏器官影响的实验研究

目的对国产医用聚丙烯酰胺水凝胶(奥美定)进行动物的实验研究,以初步证明奥美定是安全的软组织填充剂。方法将56只日本大耳白兔随机分为实验组、对照组和空白组,实验组注射奥美定配制液,对照组注射生理盐水配制液,空白组不行任何注射。分别于注射后的第1、3、6、11、12个月做血常规及肝、肾功能检查,同时将兔的内脏组织行光镜和电镜观察。结果实验组:注射奥美定后1~6个月兔内脏的组织学观察有轻度改变,6个月后逐渐转为“正常”;血常规及肝、肾功能无明显影响。与对照组和空白组比较(P>0.01),差异无显著意义。结论初步认为奥美定是安全的软组织填充剂,但尚需进一步研究及长期的临床观察。     

抗环瓜氨酸肽抗体在幼年特发性关节炎中的意义

幼年特发性关节炎(juvenile idiopathic arthritis,JIA)旧称幼年类风湿关节炎,是指16岁以下青少年不明原因的关节肿胀并持续6周以上的关节炎。JIA是儿童时期致残率最高的自身免疫性疾病．以慢性关节滑膜炎症为其主要特征。迄     

考马斯亮蓝染色在聚丙烯酰胺凝胶电泳中的应用

在研究医学媒介节肢动物与宿主相互关系过程中，经常用到聚丙烯酰胺凝胶电泳技术，以分析功能成分的变化及作用关系，通过分析蛋白凝胶电泳后的色带图谱，可识别不同的蛋白，或用凝胶电泳法分析DNA，其中的关键显色技术是考马斯亮蓝染色法。本文结合实际研究的经验，介绍一种快速显色的技术，供相关人员参考使用。本实验流程仅需三小时，且具有快速、安全、染色及观察（色带）简便等优点。     

不同液体术前急性高容量血液稀释对深静脉血栓病人血液流变学的影响

Objective To investigate the effects of acute hypervolemic hemodilution (AHH) with different fluids on blood rheology in patients with deep vein (femoral and iliac) thrombosis. Methods Thirty ASA I or II patients aged 40-64 yr who had developed deep vein thrombosis in 48 h and were scheduled for embolectomy were randomly divided into 3 groups ( n = 10 each) ; group I normal saline (NS) ; group II 6 % HES 200/0.5 ( HES) ; group IE gelofusine (GEL). AHH was performed with normal saline, 6% HES or gelofusine infusion at 20 ml·kg-1 ·h-1 for 40 min. MAP, HR and SpO2 were monitored. Blood loss, volume of blood transfusion and fluid infused and urine output during operation were recorded. Anesthesia was induced with fentanyl 3-5 fig/kg, etomidate 0.15-0.30 mg/kg, propofol 1-2 mg/kg and succinylcholine 1-2 mg/kg and maintained with 2% isoflurane and propofol infusion at 5-8 mg·kg-1·h-1 and intermittent iv boluses of vecuronium. The patients were mechanically ventilated (VT 8 ml/kg, RR 12 bpm). PaO2 and PaCO2 were maintained within normal range. Venous blood samples were obtained before and after AHH for measurement of hematocrit (Hct), whole blood viscocity (WBV) at low or high shear rates, plasma viscosity, RBC aggregation and RBC deformation. RBC aggregation index and RBC deformation index were calculated. Results MAP and HR were stable in all patients. The amount of blood transfusion and fluid infused was significantly less in group HES and GEL than in group NS. The WBV at low or high shear rates in group HES and GEL, Hct in all 3 groups and RBC aggregation index in group HES were significantly decreased after AHH, but the RBC deformation index was significantly increased in group HES. Conclusion Colloid is better than crystalloid and HES is better than gelofusine in improving intraoperative hypercoagulability and sluggish blood flow.
