补肾通络治疗糖尿病骨质疏松临床观察

目的：观察补肾通络治疗糖尿病骨质疏松症（DOP）的效果。方法：73例DOP患者随机分为治疗组37例和对照组36例。两组均予降糖治疗,治疗组以补肾通络中药治疗,对照组以复方碳酸钙片。结果：补肾通络中药能够明显改善患者的临床症状,而跟骨超声检测（quantitative uhrasoundQUS）：声音速度（speed of sound,sos）、宽波段超声衰减（bmadband ultrasound attenuation,BUA）较治疗前有显著改善。结论：补肾通络治疗DOP确切疗效,值得进一步深入研究。     

智能信息化的援藏外科继续教育模式的探索

西藏自治区那曲市海拔达4 500米,高寒缺氧的自然地理条件制约了当地医疗事业的发展。培养和建设当地的医疗人才队伍是提升那曲市医疗服务能力的关键。依托医疗人才“组团式”援藏开展的外科继续教育已经取得了较好的教学效果,但在急诊诊疗、开放式手术、实时交互等教学方面存在着较大的限制。那曲市人民医院依托“亮亮视野”远程医疗平台开展智能信息化的援藏外科继续教育,较好地克服了时间、地域对教学效果的限制,提升了援藏外科继续教育的教学效果,同时也为援藏医学继续教育模式的不断完善提供了实践依据。     

经肝静脉行永久希氏束起搏一例

常规血管路径通畅是经静脉永久起搏器植入的重要条件。锁骨下静脉,颈内静脉或上腔静脉的狭窄或闭塞会增加起搏器植入难度。本文介绍1例尿毒症左上肢血管造瘘患者,因起搏系统感染行导线移除术后双侧锁骨下静脉和颈内静脉闭塞或严重狭窄,成功完成经肝静脉永久希氏束起搏的病例。     

RGD多肽接枝聚复合导管桥接神经缺损的实验研究

Objective To investigate the effect of RGD peptide conjugated poly[ LA-(Glc-Lys) ]/βTCP/PLA nerve conduit for bridging peripheral nerve regeneration defect. Methods Forty-five male Wister rots were randomly divided into 3 groups, with 15 rats each. A 10 mm defect was created in the right sciatic nerve. In group A the gap was bridged by PLA tube. In group B RGD peptide conjugated poly[ LA-(Glc-Lys) ]/β-TCP/PLA nerve conduit was used to repair the defect. Autologous nerve graft was done in group C which served as control. Twelve weeks postoperatively nerve regeneration was evaluated by gross observation,electrophysiology, muscle weight and muscle morphometry of triceps surae, and ultrastructure of the regenerating nerve. Results Twelve weeks after the operation, nerve conduction velocity and muscle weight recovery of group B were better than those of group A. The differences were statistically significant( P < 0.05). There was no significant difference between group B and group C ( P > 0. 05). The results of histology and ultrastructure showed that nerve regeneration in group B and group C was significantly superior to that in group A.Conclusion RGD peptide conjugated poly[LA-(Glc-Lys)]/β-TCP/PLA conduit can achieve similar results in repairing sciatic nerve defect to that of autogentic nerve graft. It may be an ideal material to repair nerve defect.     

超声引导下连续髂筋膜间隙阻滞用于老年髋部骨折患者围术期镇痛的研究

目的:研究超声引导下髂筋膜间隙阻滞对老年髋部骨折患者围手术期疼痛控制及术后并发症的影响。方法:选择2021年1月至2021年9月收治的老年髋部骨折手术患者127例,按照镇痛方法不同分为连续髂筋膜间隙阻滞组(F组)和静脉镇痛对照组(C组)。其中F组62例,男19例,女43例;年龄66~95(82.4±7.2)岁;股骨颈骨折25例,股骨转子间骨折37例。C组65例,男18例,女47例;年龄65~94(81.4±8.7)岁;股骨颈骨折29例,股骨转子间骨折36例。观察两组患者围术期不同时间点的疼痛视觉模拟评分(visual analogue scale,VAS)、简易精神状态评价量表(minimental state examination,MMSE)评分、警觉-镇静评分(observer''s assessment of alertness/sedation,OAA/S)、改良Bromage评分、术后并发症及患者住院期间情况。结果:F组实施阻滞后30 min、麻醉摆放体位时,术后6、24、48 h的静息及运动VAS低于C组(P<0.05)。F组术前12 h,术后1、3 d的MMSE评分及术后3 d的OAA/S评分高于C组(P<0.05)。F组不良反应发生率、需要额外镇痛人数低于C组(P<0.05)。F组围术期镇痛满意度及住院时间均优于C组(P<0.05)。两组患者在各时间点患肢Bromage评分及术后30 d死亡率比较,差异无统计学意义(P>0.05)。结论:超声引导下连续髂筋膜间隙阻滞可为老年髋部骨折患者提供安全、有效的围术期镇痛效果,改善术后认知功能,减少术后并发症,从而缩短住院时间,提高住院期间生活质量。     

RGD多肽接枝聚复合导管桥接神经缺损的实验研究

目的 探讨RGD多肽接枝聚/β-TCP/PLA复合神经导管桥接周围神经缺损的治疗效果.方法 45只雄性成年Wister大鼠,随机分为3组,每组15只.切断右侧坐骨神经形成10 mm缺损,A组采用单纯PLA神经导管桥接缺损,B组采用RGD多肽接枝聚/β-TCP/PLA复合神经导管桥接缺损,C组采用自体神经移植.术后12周进行大体观察、电生理、小腿三头肌恢复率、组织学、超微结构等测定.结果 B组运动神经传导速度和肌肉湿重恢复率明显优于A组,差异有统计学意义(P<0.05);B组与C组相近,差异无统计学意义(P>0.05).组织学、超微结构测定发现B、C组神经再生情况明显优于A组.结论 在坐骨神经损伤修复中,RGD多肽接枝聚/β-TCP/PLA复合神经导管桥接修复效果与自体神经移植相近,可作为一种较理想的神经缺损修复材料.

“三七”“土三七”一字之差,却能要人命

正"三七"与"土三七"仅一字之差,对人体健康来说意义相距甚远。一个是名贵中药,另一个却是有毒性的草药,误食"土三七"将损伤身体,甚至危及生命。〇"土三七"引发严重肝损伤近年来,误服"土三七"的人越来越多。镇江54岁的王老先生说,当地流传着这样一个偏方:用"土三七"泡药酒喝,能够治疗跌打损伤或腰腿痛。不少人就在自家地里种上了"土三七",泡了药酒每天喝一点。我也移植了一些"土三七",晒干了泡酒喝。想治疗腰腿疼。可没喝多久,就因为
