ObjectiveTo explore the clinical value of endoscopic retrograde cholangiopancreatography (ERCP) combined with laparoscopic cholecystectomy (LC) and LC combined with laparoscopiccommom bile duct exploration and primary sture (LBDEPS) in the treatment of cholecystolithiasis complicated with choledocholithiasis in the elderly (age more than 75 years old).MethodsThe elderly patients with cholecystolithiasis complicated with choledocholithiasis in the Tianyou Hospital Affiliated to Wuhan University of Science and Technology from March 1, 2018 to June 30, 2019 were retrospectively collected, then were designed into an ERCP combined with LC therapy group (ERCP+LC group) and a LC combined with LBDEPS therapy group (LC+LBDEPS group) according to the therapy methods. The operative indexes (total operation time, general anesthesia time, intraoperative bleeding volume, LC conversion to laparotomy) and postoperative indexes (conversion to ICU, use time of ventilator in the ICU, drainage tube indwelling time, ventilation time, time of getting out of bed, postoperative hospitalization time, total hospitalization time, total hospitalization costs, stone clearance rate, and complications) were compared between the two groups.ResultsIn this study, 67 patients were collected, including 35 patients in the ERCP+LC group and 32 patients in the LC+LBDEPS group. There were no significant differences between the two groups in the terms of baseline data, such as the patients’ gender, age, preoperative symptoms, preoperative complications, number of choledocholithiasis, maximum diameter of choledocholithiasis, and diameter of common bile duct, etc. (P>0.05). Compared with the LC+LBDEPS group, the ERCP+LC group had more advantages in the terms of the total operation time, general anesthesia time, intraoperative bleeding, rate of LC conversion to laparotomy, time of ventilator use in the ICU, postoperative ventilation time, postoperative time of getting out of bed, and drainage tube indwelling time (P<0.05). The others indexes had no significant differences between the two groups (P>0.05).ConclusionsAccording to the results of this study, therapeutic efficacy of ERCP+LC and LC+LBDEPS in treatment of elderly patients with cholecystolithiasis complicated with choledocholithiasis have no significant differences, but ERCP+LC therapy has more advantages than LC+LBDEPS in total operation time, general anesthesia time, intraoperative bleeding, LC conversion to laparotomy, postoperative recovery and so on, and appropriate operation mode might be selected according to specific situation of patients and local medical conditions.
Objective To evaluate the clinical effect of vacuum sealing drainage (VSD) technology in the treatment of high perianal abscess. Methods A total of 38 cases of high perianal abscess who underwent surgery in our hospital from May. 2014 to Feb. 2016 were randomly divided into 2 groups: the VSD group (n=19) and the control group (n=19). The cases of VSD group were performed with closure of internal orifice+VSD technique, and the cases of control group were treated with radical operation of perianal abscess (low incision combined with high thread operation). The following indexes of cases in 2 groups were compared and analyzed, including postoperative pain score, wound healing time, postoperative anal function score, and prognosis. Results There were significant differences in pain score (3.53±0.70vs. 5.11±0.74), postoperative anal function score (0vs. 1), and wound healing time〔(27.58±4.95) dvs. (44.68±6.53) d〕between VSD group and control group,P<0.05. Compared with the control group, the pain score and anal function score of the VSD group were both lower, and the wound healing time was shorter. However, there was no statistically significant difference in incidence of fistula between the two groups〔5.3% (1/19)vs. 15.8% (3/19),P=0.60〕. Conclusion In the treatment of high perianal abscess, VSD technology can relieve pain in patients, shorten the wound healing time, protect the anal function, and the prognosis is as well as low incision combined with high thread operation, so VSD is a better treatment method for high perianal abscess.
Objective To investigate whether miRNA (miR)-34a mediates oxaliplatin (OXA) resistance of colon cancer cells by inhibiting macroautophagy via the transforming growth factor (TGF)-β/Smad4 pathway. Methods miR-34a expression levels were detected in colon cancer tissues and colon cancer cell lines by quantitative real-time polymerase chain reaction (qRT-PCR). Computational search, functional luciferase assay, and Western blotting method were used to demonstrate the downstream target of miR-34a in colon cancer cells. Cell viability was measured with cell counting kit-8. Apoptosis and macroautophagy of colon cancer cells were analyzed by flow cytometry and transmission electron microscopy, and expressions of Beclin1 and LC3Ⅱ protein were detected by Western blotting method. Results Expression of miR-34a was significantly reduced while expressions of TGF-β and Smad4 mRNA were increased in colon cancer patients treated with OXA-based chemotherapy. OXA treatment also resulted in decreased miR-34a expression levels and increased TGF-β and Smad4 expression levels in both parental cells and the OXA-resistant colon cancer cells. Activation of macroautophagy contributed to OXA resistance in colon cancer cells. Expression levels of Smad4 and miR-34a in colon cancer patients had a significant inverse correlation and overexpressing miR-34a inhibited macroautophagy activation by directly targeting Smad4 through the TGF-β/Smad4 pathway. OXA-induced downregulation of miR-34a and increased drug resistance by activating macroautophagy in colon cancer cells. Conclusion miR-34a mediates OXA resistance of colon cancer by inhibiting autophagy via the TGF-β/Smad4 pathway.
