Objective To introduce the methods and the advancements of early diagnosis in primary carcinoma of gallbladder (PCG), and improve the early diagnostic rate of PCG. Methods Recent relevant literatures were reviewed. Results It was difficult in early diagnosis of PCG and with a poor prognosis. Comprehending case history and careful examination and being assisted by multiple imaging methods and molecular biology technology could markedly improve the early diagnostic rate. Conclusion Comprehending the progress will contribute a lot of improving the early diagnostic rate and selecting reasonable clinical methods to be used in early diagnosis of PCG.
目的 评价3DMax补片在腹腔镜下全腹膜外修补术(totally extraperitoneal,TEP)中修补腹股沟疝的价值。方法 回顾性分析我院2009年2～6月期间腹腔镜下应用3DMax补片对18例腹股沟疝患者行TEP的临床资料，分析其手术时间、住院时间、复发和并发症发生情况。结果 18 例患者中Ⅰ型疝3例，Ⅱ型疝4例，Ⅲ型疝9例，Ⅳ型疝2例； 斜疝11例，直疝6例，股疝1例。成功完成腹腔镜下TEP 17例。1例因疝内容物为末端回肠，与疝囊粘连并局部狭窄梗阻，中转开放手术切除部分回肠。手术时间40～95 min，平均65.4 min。术后均未使用镇痛剂，术后住院时间2～7 d，平均住院5.5 d。术后发生阴囊血清肿1例，经穿刺排液后愈合良好。随访1～6个月，无复发病例。结论 腹腔镜下TEP具有创伤小、恢复快、复发率低等优点，采用预先成型的3DMax 补片使手术操作更加简便。
【Abstract】ObjectiveTo evaluate the advances in minimally invasive surgery treatment for hepatolithiasis. MethodsLiteratures about the advances in minimally invasive surgery treatment for hepatolithiasis were collected and reviewed. ResultsHepatectomy and bile duct exploration using laparoscopy can get better effect. Fibrocholedochoscopy play an important role in the course of operation and after operation for hepatolithiasis. ConclusionThe individualization treatment program should be used for hepatolithiasis. Association application of multipathway minimally invasive operation, such as laparoscopy, fibrocholedochoscopy and so on, can increase the cure rate of hepatolithiasis.
目的探讨再次手术治疗复发性结节性甲状腺肿的安全性及有效性。 方法回顾性分析2004年1月至2012年12月期间于笔者所在医院行再次手术治疗的48例复发性结节性甲状腺肿患者的临床资料。 结果本组48例患者中，再次手术行甲状腺全切除术33例，行甲状腺近全切除术15例。术中显露喉返神经32例（61条），均无喉返神经损伤发生；未能显露喉返神经16例，其中有2例发生喉返神经损伤，损伤率为12.5%，高于显露喉返神经者（P＜0.05）。术后均无永久性低钙血症发生，17例（35.4%）发生暂时性低钙血症。术后均获访0.5～8.0年，平均4.3年，无复发。 结论复发性结节性甲状腺肿再次手术行甲状腺全切除或近全切除术是安全可靠的，预防术后并发症的关键是熟悉甲状腺解剖和精细手术操作。
Objective To study the effects of L-arginine （L-Arg） on cell proliferation, inducible nitric oxide synthase (iNOS) expression and cell cycle in human colon carcinoma cell line LS174 through nitric oxide (NO) pathway. Methods LS174 cells were cultured in medium with L-Arg at different concentrations for different times. MTT method was employed to evaluate the level of the cell proliferation. The production of NO in culture supernatants of LS174 cell was detected with enzyme reduction of nitrate. The distribution of the cell cycle was detected with the flow cytometry (FCM). The expression level of iNOS in the cells was determined by Western blot and SP immunocytochemical staining method. Results The growth of LS174 was promoted by the L-Arg at low concentration (0.125 mmol/L) and inhibited at high concentrations (0.5， 2， 8 and 32 mmol/L). The level of NO was increased with the increasing concentration of L-Arg in culture medium. To compare with the control group, the ratio of cells at S phase was increased after 48 hours’ treatments with high concentrations (0.5, 2, 8 and 32 mmol/L) of L-Arg (P＜0.05, P＜0.01); while there was no obvious difference after treatments with low concentration (0.125 mmol/L) of L-Arg (Pgt;0.05). With the increase of the concentration of L-Arg, the expression of iNOS was increased as compared with control group. The higher the concentration of L-Arg was, the better the effect. Conclusion L-Arg can induce the expression of iNOS resulting in increase the production of nitric oxide (NO). Low concentration of L-Arg can promote the growth of LS174 cells, while high concentration ones can inhibit growth and proliferation. The high concentration of L-Arg could induce S phase arrestion in the cell cycle.
