  • 门静脉动脉化在肝门部胆管癌根治术中的应用价值

    目的 探讨肝动脉重建加门静脉动脉化在肝门部胆管癌根治性切除术中应用的安全性和有效性。 方法 对笔者所在医院 2016 年 10 月收治的 1 例 Bismuth-Corlette 分型Ⅳ型肝门部中晚期胆管癌患者施行扩大左半肝切除加尾叶切除术并采用肝固有动脉与门静脉吻合行门静脉动脉化的患者进行回顾性分析。 结果 患者术后恢复顺利,肝功能逐渐恢复正常,术后未发生急性肝功能衰竭、吻合口栓塞、胆道感染等并发症,随访截至 2017 年 8 月(术后 10 个月)未发现门静脉高压症及肿瘤复发征象。 结论 该例患者的结果提示,门静脉动脉化在肝门部胆管癌行扩大根治术中使用可防止急性肝功能衰竭,促进术后肝功能恢复,提高肝门部胆管癌的根治性切除率。

  • Expression of long non-coding RNA GAS5 in hepatocellular carcinoma tissues and its clinical significance

    ObjectiveTo investigate the expression of growth arrest-specific 5 (GAS5) mRNA and its clinical significance in hepatocellular carcinoma.MethodsThe expression of GAS5 mRNA in the hepatocellular carcinoma tissues and corresponding adjacent tissues were detected by real time-PCR. The relationship between the expression of GAS5 mRNA and clinicopathological characteristics were analyzed by SPSS 19.0 software.ResultsThe expression of GAS5 mRNA in hepatocellular carcinoma tissues was significantly lower than that of the adjacent tissues (P<0.01). The expression of GAS5 mRNA was related to tumor size, tumor number, lymph node metastasis, clinical TNM stage, alpha fetoprotein level, and tumor differentiation (P<0.05). Cox hazard model results showed that low expression of GAS5 mRNA was associated with poor prognosis (P<0.05).ConclusionGAS5 mRNA is expected to be a diagnostic and prognostic marker for patients with hepatocellular carcinoma.

  • Correlation study of immune function and inflammatory factors levels in patients with hepatocellular carcinoma and in vitro high-throughput drug sensitivity

    ObjectiveTo analyze the correlations between the immune function and inflammatory factors levels of patients with hepatocellular carcinoma (HCC) and the results of in vitro high-throughput drug sensitivity, and to provide a reference for personalized drug selection for patients with HCC. MethodsThe patients with HCC who met the inclusion criteria from December 2019 to June 2021 in the First Affiliated Hospital of Chongqing Medical University were included. The HCC cells were used to perform in vitro high-throughput drug sensitivity screening, the result was classified into sensitive and insensitive. The correlations between drug sensitivity results and immune function and inflammatory factors levels of corresponding patients were analyzed, and the relation between these indexes (P<0.05) and drug sensitivity of HCC cells to drugs or combination regimen of drugs was further analyzed by univariate logistic regression. ResultsA total of 74 patients with HCC were included in this study. The results showed that the level of interleukin-6 was negatively correlated with sorafenib, caffezomib, gemcitabine, oxaliplatin + epirubicin + irinotecan + 5-fluorouracil, oxaliplatin + irinotecan + epirubicin, and oxaliplatin + epirubicin regimens on the inhibition rates of HCC in vitro (P<0.05), and positively correlated with bortezomib (P<0.05). However, the level of interleukin-6 was not related to the sensitivity of HCC cells to these single drugs or combined regimens (P>0.05). Meanwhile it was found that tumor necrosis factor (TNF)-α was negatively correlated with cabotinib, apatinib, caffezomib, and epirubicin on the inhibition rates of HCC in vitro (P<0.05), and positively correlated with epirubicin (P<0.05). But only it was found that tumor necrosis factor-α level was related to the sensitivity of HCC cells to epirubicin (P<0.05). ConclusionsTumor necrosis factor-α level in peripheral blood of patients with HCC has a certain relation with epirubicin on inhibition rate of HCC in vitro and it might have a certain value in predicting sensitivity of HCC cells to epirubicin. Meanwhile, although it is found that level of IL-6 is related to sorafenib, caffezomib, gemcitabine, or including combination regiems including oxaliplatin and epirubicin on inhibition rates of HCC in vitro, their value is not found in predicting sensitivity of HCC cells to these single drugs or combined regimens.

  • Clinical application of “Double R” pancreaticojejunostomy in laparoscopic pancreaticoduodenectomy

    ObjectiveTo investigate the clinical effect of “Double R” pancreatojejunostomy in laparoscopic pancreaticoduodenectomy (LPD).MethodsThe clinical data of 20 patients underwent “Double R” pancreaticojejunostomy in the LPD from November 2018 to December 2019 in this hospital were collected retrospectively. The duration of pancreaticojejunostomy, incidence of postoperative pancreatic fistula, incidence of other complications, mortality, length of stay, and other clinical outcomes were analyzed.ResultsThere were 5 males and 6 females. The age was (56±10) years old. The body mass index was (22.6±4.4) kg/m2. The LPDs were successfully performed in all 20 patients, no patient transferred to the laparotomy, and no patient died within 30 d. There were 6 patients with papillary adenocarcinoma of the duodenum, 5 patients with adenocarcinoma of the lower part of the common bile duct, 2 patients with adenocarcinoma of the pancreatic duct, 3 patients with serous cystadenoma of the pancreatic head, 2 patients with intraductal papillary myxoma of the main pancreatic duct of the pancreatic head, 1 patient with duodenal adenoma with high grade intraepithelial neoplasia, 1 patient with metastatic renal clear cell carcinoma of the pancreatic head, 5 patients with soft pancreas, 12 patients with medium texture, 3 patients with hard texture. The diameter of distal pancreatic duct was (2.1±1.7) mm. The operative time was (380±69) min, the duration of pancreaticojejunostomy was (29±15) min, the intraoperative blood loss was (180±150) mL, the postoperative time of anal exhaust (2.2±0.8) d, postoperative time of fluid intake (3.5±1.1) d, postoperative time of half fluid intake (5.5±0.7) d, postoperative time of hospitalization (14±10) d. There were 3 complications in 2 patients, one of which suffered the pulmonary infection, the other suffered the delayed gastric emptying and gastrointestinal anastomosis bleeding, no bile leakage and abdominal hemorrhage happened. There were 2 cases of pancreatic fistula after the operation, all of them were biochemical pancreatic fistula.Conclusions“Double R” pancreaticojejunostomy method has some advantages of convenient operation, short operation time, and low incidence of pancreatic fistula. However, due to the limited sample size, its safety and feasibility still need to be verified by larger samples and more institutions.
