  • Clinical Analysis of Risk Factors of Postoperative Cognitive Dysfunction in Elderly Patients after Abdominal Surgery

    ObjectiveTo analyze the risk factors of postoperative cognitive dysfunction (POCD) in elderly patients after abdominal surgery. MethodsThe clinical data of 2 286 patients over 60 years old after abdominal surgery were retrospectively analyzed, which were divided into non-POCD group with 2 248 patients and POCD group with 38 patients. The influencing factors of POCD in elderly patients after abdominal surgery, including the age, gender, anesthetic way, the premedication, cormobided with lung or heart disease, diabetes, jaundice, anemia or hypoproteinemia, the duration of surgery, and postoperative analgesia protocols, were analyzed between two groups. ResultsThe age, anesthetic way, cormobided with lung or heart disease, diabetes, jaundice, with or without continuous postoperative effective analgesia, and surgery duration over four hours were relevant with POCD (Plt;0.05), while gender, the premedication, and preexisted anemia or hypoproteinemia were not relevant with that (Pgt;0.05). ConclusionAge over 70 years, general anaesthesia, cormobided with lung or heart disease, diabetes, jaundice, surgery duration over four hours, and incomplete postoperative analgesia are the risk factors of POCD after abdominal surgery.

  • Experience of toatal laparoscopic radical resection of hilar cholangiocarcinoma: a report of 14 cases

    ObjectiveTo investigate the feasibility, safety and clinical effect of total laparoscopic radical resection of hilar cholangiocarcinoma.MethodsRetrospectively summarized the 14 patients with hilar cholangiocarcinoma, who underwent total laparoscopic radical resection of hilar cholangiocarcinoma in the Affiliated Hospital of Xuzhou Medical University from April 2016 to June 2018. Collected the clinical data of those patients, including 7 cases of Bismuth type Ⅰ, 5 cases of Bismuth type Ⅱ, and 2 cases of Bismuth type Ⅲb.ResultsTotal laparoscopic radical resection of hilar cholangiocarcinoma were performed successfully in all 14 patients. The operative time was 190–400 min (median time of 285 min) and the amount of intraoperative blood loss was 100–500 mL (median amount of 175 mL). There was no death case during the perioperative period. Postoperative pathological results showed that all cases accorded with bile duct adenocarcinoma, resection margins of them were negative, amount of lymph node was detected 6–15 per case (median amount of 8 per case), and 3 patients were inspected with peritumoral lymph node metastasis. Two patients were combined with postoperative bile leakage, one of whom was complicated with an abdominal infection, and both were cured and discharged after conservative treatment. All patients were followed-up regularly within 3–24 months (median followed-up period of 16 months). One of them recurred within 12 months after the operation. The remaining patients have survived well so far.ConclusionUnder the operation of the experienced surgeon, total laparoscopic radical resection of hilar cholangiocarcinoma is safe, feasible and effective in the short term.

  • Influence on Expressions of Insulin Receptor Substrate 1 and Ubiquitin-Protein in Skeletal Muscle of Non-Obese Rats with Type 2 Diabetes Mellitus Following Gastric Bypass Operation

    ObjectiveTo observe expre with ssions of insulin receptor substrate 1(IRS-1) and ubiquitin-protein in skeletal muscle of non-obese rats with type 2 diabetes mellitus following gastric bypass operation (GBP), and to investigate possible mechanism of GBP in improving insulin resistance. MethodsMale GK rats were randomly divided into diabetic operation group (DO group), diabetic sham operation group (DSO group), and diabetic control group (DC group), 8 rats in each group; besides 8 male Wistar rats were served as normal control group (NC group). Fasting body weight (FBW), fasting plasma glucose (FPG), and fasting insulin (FINS) were measured respectively before operation and on week 1, 2, 4 and 8 after operation. Homeostasis model-insulin resistant (HOMA-IR) index was calculated respectively before operation and on week 8 after operation. The expressions of IRS-1 protein and ubiquitin-protein in skeletal muscle were detected by using Western blot method on week 8 after operation. Results① Compared with the preoperative levels, the FBWs on week 1, 2, and 4 after operation markedly decreased (P < 0.05), but it recovered to the preoperative level on week 8 after operation (P > 0.05) in the DO group; which in the DSO group decreased on week 1 after operation (P < 0.05) and then increased on week 4 after operation (P < 0.05); which in the DC group or the NC group increased continuously and had a significant difference on week 8 after operation (P < 0.05).② The FPGs in the DO, DSO and DC groups were significantly higher than those of the NC group before operation (P < 0.05), which in the DO group decreased from (9.10±0.98) mmoL/L before operation to (5.70±0.91) mmol/L on week 8 after operation (P < 0.05) and were significantly lower than those of the DSO group or the DC group on week 2, 4, and 8 after operation (P < 0.05); which in the DC group, DSO group and NC group had no obviously changes between before and after operations (P > 0.05). ③ The FINS had no significant differences among these four groups before operation (P > 0.05), which in the DO group obviously increased[(9.64±1.59) mU/L] on week 2 after operation (P < 0.05) and then obviously decreased[(6.58±1.05) mU/L] on week 8 after operation (P < 0.05) and significantly lower than those of the DSO group or the DC group on week 8 after operation (P < 0.05), while which had no significant difference between before and after operations in the DSO group, the DC group, or the NC group (P > 0.05). ④ The HOMA-IR index in the DO, DSO or DC group was significantly higher than that of the NC group before operation (P < 0.05), which in the DO group markedly decreased from 3.18±0.50 before operation to 1.96±0.63 on week 8 after operation (P < 0.05) and significantly lower than that of the DSO group or the DC group on week 8 after operation (P < 0.05), while which had no significant difference between before and after operations in the DSO group, the DC group, or the NC group (P > 0.05). ⑤ The expression of IRS-1 protein in the DO group was significantly higher than that in the DSO group (P < 0.05) or the DC group (P < 0.05) on week 8 after operation. While there was no significant difference between the DSO and the DC group after operation (P > 0.05). ⑥ Compared with the NC group, the expression of ubiquitin-protein was significantly increased in the DO group, the DSO group, or the DC group (P < 0.05). Compared with the DSO group or the DC group, the expression of ubiquitin-protein was significantly decreased in the DO group on week 8 after operation (P < 0.05), especially it was most obvious near the molecular weight of 180×103. While there was no significant difference between the DSO group and the DC group after operation (P > 0.05). ConclusionsExpression of IRS-1 protein in skeletal muscle insulin signaling pathway in type 2 diabetes mellitus rats following GBP is increased, it might be associated with decreasing ubiquitin-protein level in skeletal muscle, thus reduces the IRS-1 ubiquitin-degradation, increase insulin sensitivity, and improve insulin resistance of skeletal muscle.

  • Influence on the expression of SPARC and GLUT-4 protein in adipose tissue ofnon-obese GK rats after gastric bypass operation

    ObjectiveTo investigate the expressions of glucose transporter-4 (GLUT-4) and secreted protein acidic and rich in cysteine (SPARC) in adipose tissue of Goto-Kakizaki (GK)/Wister rats after gastric bypass operation (GBP), and to explore the possible mechanism of GBP improving insulin resistance.MethodsHealthy male GK rats were randomly divided into diabetic operation group (DO group, underwent GBP), diabetic sham operation group (DS group, underwent sham-operation), and diabetic control group (DC group, received no-treatment), Wister rats were set as normal control group (NC group, received no-treatment). The weight, fasting blood glucose (FPG), fasting serum insulin (Fins), and HbA1c were measured before operation and at the 1st, 2nd, 4th, and 8th week after operation. Quantitative insulin sensitivity check index (QUICKI) was measured in before operation and at the 8th week after operation, and the expressions of GLUT-4 and SPARC protein in adipose tissues were measured by Western Blot method at the 8th week after operative too.Results① Weight: the weight of the DO group was lower than preoperative at the 2nd and 4th week after GBP (P<0.05), but increased to the normal level at the 8th week after GBP (P>0.05). The weight of the DO group was lower than those of the DS group, DC group, and NC group at the same time point of 2nd, 4th, and 8th week (P<0.05). ② FPG: the FPG level of the DO group was lower than preoperative at the 2nd, 4th, and 8th week after GBP (P<0.05), and lower than those of the DS group and the DC group from 2nd to 8th week after GBP (P<0.05). The FPG level between the DS group and the DC group had no statistical significance (P>0.05). ③ Fins: the Fins level of the DO group was higher than preoperative at the 2nd week after GBP (P<0.05), and decreased gradually at 4th and 8th week but not significantly differed from the NC group at the same time point. At the 2nd week after GBP, the Fins level of the DO group was higher than those of the DS group and the DC group (P<0.05), but there was no statistical significance between the DS group and the DC group (P>0.05). ④ HbA1c: the HbA1c level of the DO group started to decrease but there was no statistical significance between preoperative and all time after GBP (P>0.05). There was no statistical significance among the 4 groups at the 8th week after GBP (P>0.05). ⑤ QUICKI: at the 8th week, the QUICKI value of the DO group was higher than preoperative (P<0.05), and at the same time, the QUICKI value of the DO group and the NC group were higher than those of the DS group and the DC group (P<0.05), but there was no statistical significance between the DO group and the NC group (P>0.05), as well as the DS group and the DC group (P>0.05). ⑥ GLUT-4 protein and SPARC protein: the expression of GLUT-4 protein of the DO group was dramatically higher than those of the DC, DS, and NC group (P<0.05), and the expression of SPARC protein of the DO group was dramatically lower than those of the DC, DS, and NC group (P<0.05) at the 8th week. But the expressions of GLUT-4 and SPARC protein had no statistical significance among the DS, DC, and NC group at the 8th week after GBP (P>0.05).ConclusionGBP may improve and increase the sensitivity of insulin resistance by regulating the expressions of GLUT-4 and SPARC protein in adipose tissue of GK rats.

  • Predictive value of amylase content of drainage fluid for clinically relevant postoperative pancreatic fistula after laparoscopic pancreaticoduodenectomy

    ObjectiveTo investigate value of drainage fluid amylase content and other risk factors in predicting clinically relevant postoperative pancreatic fistula (CR-POPF) after laparoscopic pancreaticoduodenectomy (LPD).MethodsThe clinical data of 166 patients who underwent LPD in this hospital from January 2017 to December 2019 were retrospectively analyzed. The independent risk factors of CR-POPF after LPD were analyzed. And the sensitivity and specificity of drainage fluid amylase content obtained on postoperative day 1 and 3 (Abbreviated as DFA1 and DFA3, respectively) in predicting CR-POPF by receiver operating characteristic (ROC) curve.ResultsA total of 166 patients underwent LPD were collected in this study. The CR-POPF occurred in 16 (9.6%) patients and all of them were grade B. The DFA1 (P=0.037), DFA3 (P<0.001), and positive bacterial culture of drainage fluid after operation (P=0.020) were the independent risk factors of CR-POPF after LPD (P<0.05) by the logistic regression multivariate analysis. The area under the ROC curve of the DFA1 and DFA3 in predicting CR-POPF was 0.880 [95%CI (0.812, 0.949)] and 0.912 [95%CI (0.853, 0.971)] respectively, and the corresponding best critical value was 3 925 and 939 U/L, and the sensitivity was 100% and 100%, specificity was 64.0% and 70.7%, respectively.ConclusionFor patients with DFA1>3 925 U/L, DFA3>939 U/L, and positive bacterial culture of drainage fluid after operation, preventive measures should be made to avoid CR-POPF.
