ObjectiveTo more comprehensive understanding the survival situation of donors after liver transplantation, which can be applied to clinical diagnosis and treatment. MethodsThe related literatures in recent years of living donor liver transplantation (LDLT) postoperative complications, quality of life, and liver regeneration were reviewed, and the donors postoperative survival situation were investigated. ResultsLDLT has become an option, It is safe and feasible for healthy adults to donate partial liver for LDLT. ConclusionsDonor postoperative survival situation is very important, and it affect the development of LDLT.To improve donors postoperative survival situation, we still need more efforts.
ObjectiveTo analyze risk and therapy strategy of tiny gallbladder stones during laparoscopic cholecystectomy (LC).MethodThe clinical data of 932 patients with tiny gallbladder stones performed LC from September 2013 to July 2014 were analyzed retrospectively.ResultsThe LC was successful in all the patients. The gallbladders were ruptured in 86 (9.23%) patients during operation. Following up 1-3 months, there were 26 patients with right upper abdominal pain and with residual small stones in the abdominal cavity, 57 patients without uncomfortable symptoms and without residual gallstone, 2 cases complicated with lesser abdominal abscess, 1 case complicated with incision infection. The incisional hernia and acute pancreatitis were not found.ConclusionsThe gallbladder with full of tiny stones performed LC easily leads to choledocholithiasis or acute pancreatitis. If intraoperative gallbladder rupture, the tiny stones might be residual in the peritoneal cavity and lead to abdominal infection or abscess, and incision infection or trocar site hernia. Specific operation could effectively avoid adverse complications.
ObjectiveTo investigate the clinical therapeutic effect of silver ions dressing for patient with diabetic foot ulcers. MethodsAccording to the diagnostic and classification criteria of diabetes and diabetic foot of World Health Organization (WHO), outpatients and inpatients with diabetic foot ulcers admitted to the Department of Burns and Plastic Surgery of Dazhou Central Hospital from October 2013 to May 2015 were randomly divided into a silver ion dressing treatment group and a traditional dressing treatment group. The effective rate, time of occurrence of granulation tissue, wound healing time and wound area reduction ratio between the two groups were compared by using SPSS17.0 software. ResultsA total of 80 patients were included, of which 40 patients in each group. Compared with the control group, the total effective rate was higher (92.5% vs. 62.5%, P=0.001), the occurrence time of granulation tissue (6.4±0.72 vs. 10.8 ±1.9, P=0.000) and wound healing time (31.3±8.2 vs. 47.4±11.5, P=0.000) were shorter, and the wound area reduction ration was greater (46.3±7.6 vs. 32.6±6.1, P=0.000) in the silver ions dressing group with significant differences. ConclusionThe effects of silver-containing dressings is superior to Vaseline dressing in the treatment of diabetic foot ulcers.
ObjectiveTo evaluate the safety and feasibility of laparoscopic resection of primary retroperitoneal tumors. MethodClinical data of 52 patients diagnosed as primary retroperitoneal tumor who underwent laparoscopic resection in Peking University Third Hospital from January 2006 to December 2015 were retrospectively collected and analyzed. ResultsFifty two patients were included in the review. In 21 patients (40.3%), tumors were adjacent to major vessels (such as inferior vena cava, superior mesenteric vein, and the splenic vessel), tumors of 31 patients (59.7%) were away from major vessles. Two operations (3.8%) were converted to hand-assistant and 2 operations (3.8%) were converted to laparotomy due to tight adherence to major vessels. The mean value of operative time was 171.4-minute (60-520 minutes) and the mean value of length of incision was 2.8 cm (1-15 cm), the mean value of estimated blood loss was 86.4 mL (10-1 150 mL), 2 patients needed blood transfusion. The mean value of time of returning to diets was 1.5-day (1-5 days) and the mean value of length of postoperative hospital stay was 4.9-day (1-16 days). There was no major postoperative complications or death. Follow up was available for 47 patients at a median time of 62.0-month (4-120 months). Three patients with retroperitoneal liposarcomas experienced recurrence at 31, 34, and 48 months after operation, 1 patient with mucinous peripheral neurilemmoma experience recurrence at 69 months after operation, all of which underwent further resection, with others experiencing no recurrence or metastasis. Three patients died in reason of other diseases. ConclusionsLaparoscopic surgery can be performed safely in the treatment of primary retroperitoneal tumors, even when a tumor adjacent to major vascular structures.
ObjectiveTo investigate regulation mechanism of glypican-3 (GPC3) on Hippo signaling pathway and its effects on biological behavior of hepatocellular carcinoma Huh7 cells. MethodsShort hairpin RNAs (shRNA) targeting GPC3 and Yes-associated protein 1 (YAP1) genes were constructed. All of the shRNAs were transfected into Huh7 cells by liposome transfection in order to screen out the stable expression cell lines. The expressions of GPC3 and YAP1 in Huh7 cells were detected by PCR and Western blot in order to screen out the effective shRNAs. The proliferation, invasion, and apoptosis of Huh7 cells were detected by Edu cell proliferation assay, transwell, and flow cytometry. GPC3 shRNA transfection experiments were divided into 6 groups:non-transfection group, empty vector group, GPC3-714-shRNA group, GPC3-647-shRNA group, GPC3-1718-shRNA group, and GPC3-2134-shRNA group. YAP1 shRNA transfection experiments were divided into 6 groups:non-transfection group, empty vector group, YAP1-906-shRNA group, YAP1-1363-shRNA group, YAP1-1666-shRNA group, and YAP1-2895-shRNA group. GPC3 regulation experiments were divided into 5 groups:non-transfection group, empty vector group, GPC3-1718-shRNA group, GPC3-1718-shRNA+ rhYAP1 group, and YAP1-1666-shRNA group. Results① GPC3-1718-shRNA and YAP1-1666-shRNA plasmids were successfully constructed to silence the expressions of GPC3 and YAP1. ② The expressions of GPC3 mRNA and protein in each transfection group were significantly lower than those in the non-transfection group (P<0.05) and the empty vector group (P<0.05), while which in the GPC3-1718-shRNA group was significantly lower than those in all the other transfection groups (P<0.05). The expressions of YAP1 mRNA and protein in each transfection group were significantly lower than those in the non-transfection group and empty vector group (P<0.05), while which in the YAP1-1666-shRNA group was significantly lower than those in all the other transfection groups (P<0.05). ③ The expressions of YAP1 mRNA and protein in the GPC3-1718-shRNA group and the YAP1-1666-shRNA group were significantly lower than those in the non-transfection group (P<0.05) and the empty vector group (P<0.05), while which in the GPC3-1718-shRNA+rhYAP1 group were significantly higher than those in the GPC3-1718-shRNA group (P<0.05) and the YAP1-1666-shRNA group (P<0.05). ④ Compared with the non-transfection group and the empty vector group, the abilities of cell proliferation and invasion in the GPC3-1718-shRNA group and the YAP1-1666-shRNA group were significantly decreased, and the cell apoptosis was significantly increased (P<0.05); The cell proliferation, invasion, and apoptosis in the GPC3-1718-shRNA+rhYAP1 group were significantly improved (P<0.05). ConclusionGPC3 is likely to affect biological behavior of hepatocellular carcinoma Huh7 cells through regulation of YAP1 in Hippo signaling pathway.
