南蛇藤提取物对Hepa1-6荷瘤小鼠肝癌移植瘤及血管生成的影响

目的观察南蛇藤乙酸乙酯提取物对Hepa1-6细胞荷瘤小鼠肝癌移植瘤及血管生成的影响。方法将C57BL/6小鼠随机分为正常组、模型组、顺铂组及南蛇藤高、中、低剂量组,每组10只。除正常组外,其他各组于左前肢腋部皮下接种小鼠肝癌细胞株Hepa1-6(1×106)0.1ml/只。接种后2周,顺铂组腹腔注射顺铂1mg/kg,南蛇藤低、中、高剂量组分别灌胃,药液浓度为10、20、40mg/kg,连续给药28d,末次给药24h后,检测肿瘤重量、移植瘤组织内肿瘤细胞的凋亡,检测移植瘤组织内血管内皮生长因子(VEGF)的表达。结果与模型组相比,南蛇藤提取物高、中、低剂量组平均瘤重均有所减少(P<0.05或P<0.01);南蛇藤中、高剂量组移植瘤内凋亡的肿瘤细胞较模型组明显增多,同时VEGF的表达较模型组明显减少。结论一定浓度的南蛇藤乙酸乙酯提取物有抑制肿瘤生长的作用,其机制可能与促进肿瘤细胞凋亡及抑制肿瘤血管生成有关。     

南蛇藤总萜对Hepal-6荷瘤小鼠VEGF、CECs的影响

目的 观察南蛇藤总萜对Hepal-6荷瘤小鼠外周血VEGF、CECs的影响.方法 采用常规无菌接种技术制作小鼠肝癌Hepal-6移植性肿瘤模型,观察南蛇藤总萜高、中、低剂量(40 mg/kg、20 mg/kg、10 mg/kg)对Hepal-6荷瘤小鼠外周血VEGF、CECs表达的影响.结果 南蛇藤总萜在20 mg/kg时,外周血VEGF (45.24±21.36) pg/ml、CECs (0.83±0.10)％表达明显降低,与阴性对照组(0.9％生理盐水)比较,差异有统计学意义(P＜0.01).结论 南蛇藤总萜可明显降低VEGF、CECs表达,这一作用可能与南蛇藤总萜抑制肝癌血管生成有关.     

应用预控出血的包皮中远段环形剥除术治疗包皮过长

Objective To investigate the middle and distal circum peeling with bleeding control technique for redundant prepuce. Methods The middle and distal part of prepuce was eireum peeled with bleeding control and electrical scalpel. More preputial inner plate was reserved. Results From January 2004 to July 2008, 51 patients with redundant prepuce were treated with this procedure. The average blood loss was 1 ～2 ml with minimal edema. The proportion of inner and outer plates was suitable. Conclusions This teelmique has the advantages of minimal blood loss and slight edema. The cosmetic result is also satisfactory.

鼻唇沟透明质酸注射填充术:应用钝针与锐针安全性和有效性的比较

目的对比应用钝针与锐针对鼻唇沟行透明质酸注射填充的安全性和有效性。方法自2015年5月至2016年10月,应用透明质酸对60例鼻唇沟凹陷求美者行鼻唇沟注射填充。随机分为两组,每组30例求美者。钝针组应用27 G钝针进行注射,锐针组应用27 G锐针进行注射。观察两组临床效果、维持时间及并发症发生情况。结果本组求美者获随访1～9个月,两组修复效果均较明显,两组总有效率差异无统计学意义(P0.05);局部肿胀发生率钝针组高于锐针组(P0.05);淤青、局部不平整和丁达尔现象的发生率锐针组高于钝针组(P0.05)。结论通过透明质酸注射填充可以安全、有效地修复鼻唇沟凹陷,锐针注射可以对皮肤表面形态进行更精细的雕刻,钝针注射更有利于降低血管栓塞等相关并发症的发生风险。
