青年性前部视网膜劈裂锯齿缘断离及视网膜脱离

目的：探讨青年性前部视网膜劈裂锯齿缘断离及视网膜脱离的临床特点、治疗及其预后。方法：对青年性前部视网膜劈裂锯齿缘断离合并视网膜脱离患者10例20只眼进行常规检眼镜眼底及Goldmann三面镜联合巩膜压陷检查，根据不同情况进行激光光凝，或巩膜冷凝外加压手术治疗，并随访1～5年。结果：共lO例，年龄17～32岁，8例为双眼患病，病变位于颞下，双侧对称。11眼同时患有前部视网膜劈裂、锯齿缘断离及视网膜脱离，3眼患有前部视网膜劈裂及锯齿缘断离，1眼仅有前部视网膜劈裂，3眼仅有锯齿缘断离其中2眼合并视网膜脱离。13眼合并视网膜脱离者采用巩膜冷凝外加压术，全部一次治愈，5眼行激光封闭锯齿缘断离及劈裂区。随访期间未见视网膜脱离，视力均有不同程度提高。结论：青年性前部视网膜劈裂锯齿缘断离及视网膜脱离有典型的临床特点，尽早发现、适宜治疗，预后良好。

益母草防治初发期急性肾小管坏死的实验研究

ＳＤ成年雄性大鼠，禁止１６小时，肌注甘油引起急性肾小管坏死（ＡＴＮ），于其初发期给予不同药液，观察到益母草组３、２４及４８小时Ｂｃｒ升高值，２４及４８小时ＢＵＮ升高值均明显低于自来水组和单纯禁水组，而与校正对照异搏停组近似，肾组织损伤程度亦明显减轻。结果表明，益母草对初发期急性肾小管坏死（ＩＡＴＮ）有一定的防治作用。

颅脑伤患者脑氧代谢监测

颅脑创伤患者病情复杂 ,CT、NMR只能反应形态结构上的损害 ,临床医生需要既行之有效又简便易行的方法来估计伤情及预后 ,并且指导治疗。许多学者发现颅脑创伤就象全身其他部位的创伤一样 ,伤后即可引起机体的应激反应和一系列代谢紊乱 ,这些代谢紊乱可以造成继发性脑损害。代谢紊乱涉及的范围很广 ,如氧代谢、能量代谢、分解合成代谢 ,并且各器官的代谢紊乱又各具特点。因为发生继发性脑缺血缺氧的患者病死率和病残率均明显增高 ,所以多数学者认为 ,造成继发性脑损害最重要的病因是脑组织的氧代谢异常[1 ] 。另外脑的氧代谢指标在危重患者…     

Effect of autocontrol micromotion intramedullary interlocking nail on fracture healing： an experimental study

Objective: To investigate the effect of autocontrol micromotion locking nail ( AMLN ) on experimental fracture healing and its mechanism. Methods: 16 goats undergoing both sides of transverse osteotomy of the femoral shafts were fixed intramedullary with AMLN and Gross-Kempf (GK) nail, respectively. The follow-up time was 7, 14, 28 and 56 days. Roentgenographic, biomechanical, histological, scanning electromicroscopic and biochemical analyses were done. Results: (1) The strength of anticompression, antiflexion and antitorsion in the fractural end in the AMLN-fixed group was higher than that of GK nail-fixed group; whereas, the rate of stress shelter in the fractured end decreased significantly (P<0.01). (2) The content of the total collagen, insoluble collagen, calcium and phosphate in the AMLN-fixed group was higher than that in the GK nail-fixed group (P<0.05). (3) Histological observation and quantitative analysis of calluses revealed that AMLN could promote the growth of bridge calluses and periosteum calluses. Hence the facture healing and remolding process achieved early, which was much better than traditional GK nail fixation. (P<0.05). (4) 7-14 days postoperation, the calluses of AMLN-fixed group was flourish and camellarly arranged and the collagen fibril formed constantly in the absorption lacuna of bone trabecula. 28-56 days postoperation, the collagen fibril was flourish around the absorption lacuna and was parallel to the bone's longitudinal axis. Active bony absorption and formation were seen, so was remolding and rebuilding. Haversian system was intact and the bony structural net was very tenacious because of the deposition of calcium salt. None of the above findings was observed in the GK nailfixed group. Conclusions: The design of AMLN accords well with the plastic fixation theory. As the geometry ametabolic system constituted by the intramedullary fixation instruments and the proximal and distal end of the fracture is very firm and stable, the disturbance to the physical stress distributed in the fractural end is light. The generation and conduct of the intermittent physical stress between the fractural parts could reach the balance between stress conduct and stress protection. The feature that the healing and remolding take place at the same time speeds up the fractural healing process.
