ABSTRACT
Objective To investigate the clinical significance of serum miR-187 and miR-143 in the development and diagnosis of gallbladder cancer.Methods 75 serum samples in patients with gallbladder cancer were selected as gallbladder cancer group.75 serum samples in patients with gallbladder benign disease and 45 serum samples in healthy physical examinations at same period were selected as the benign gallbladder disease group and healthy control group.Quantitative RT-PCR was used to detect the serum miR-187 and miR-143 expression in each group,and the expression of those related with the clinicopathological factors,the proliferation and migration of gallbladder cancer cells,and the efficacy in diagnosis of gallbladder cancer was observed.Results The serum miR-187 expression in gallbladder cancer group was significantly higher than that in benign gallbladder disease and healthy control;the serum expression of that in benign gallbladder disease was significantly higher than that in healthy control;after surgery,the expression of that was significantly lower than that before treatment (all P ＜ 0.05).The serum expression of miR-143 in gallbladder cancer group was significantly lower than that in benign gallbladder disease and healthy control;the serum expression of that in benign gallbladder disease was significantly lower than that in healthy control;after surgery the serum expression of that was significantly higher than that before surgery (all P ＜0.05).The serum expression levels of miR-187 and miR-143 in gallbladder cancer were not correlated with gender and age (both P ＞ 0.05),and were significantly correlated with Nevin stage,TNM stage,differentiation and lymphatic metastasis (all P ＜ 0.05).Furthermore,it was confirmed that miR-187 promoted the proliferation and migration of gallbladder cancer cells in vitro,while miR-143 inhibited the proliferation and migration.In the diagnosis of gallbladder,the diagnostic efficacy of miR-187 and miR-143 was significantly better than that of CA199 and CA242 (both P ＜ 0.05).Combined detection could further improve the efficacy in diagnosis of gallbladder cancer.Conclusions miR-187 and miR-143 are involved in the development of gallbladder cancer.Combined detection of serum miR-187 and miR-143 in gallbladder cancer has a high diagnostic efficiency in the diagnosis of gallbladder cancer.
ABSTRACT
Objective:To investigate the diagnosis, classification and treatment of pancreatic duct stones (PDS) .Methods:Clinical data and prognosis of 32 patients with PDS treated in our hospital from Jan. 2010 to Dec. 2019 were retrospectively analyzed. The treatment methods were summarized.Results:All 32 cases were diagnosed with PDS by imaging examinations such as B ultrasonography, CT, endoscopic retrograde cholangiopancreatography (ERCP) or magnetic resonance cholangiopancreatography (MRCP) . The diagnosis accuracy was 81.3% (26/32) for B-ultrasound, 86.2% (25/29) for CT, 90.4% (19/21) for MRCP, and 100% (8/8) for ERCP. According to the location of stones and intraoperative exploration, the 32 patients were divided into 3 groups: Type I, 17 patients, the stones were located in the main pancreatic duct; TypeⅡ, 11 patients, the stones were located in both main and branch pancreatic duct; Type Ⅲ, 4 patients, the stones were located in the branch pancreatic duct. Different treatment methods were employed according to the different types. No patient died in the perioperative period. 11 (34.3%) patients had postoperative complications. 3 (9.3%) patients had postoperative residual stones. 32 cases were followed up for a period of 6 to 60 months. The abdominal pain and steatorrhea disappeared or significantly improved postoperatively. 2 patients complicated with pancreatic cancer died 12 to 35 months after operation.Conclusions:The treatment and diagnosis of the PDS still remains complicated. Imaging examinations are the main methods for diagnosis of PDS. The accurate classification and individual treatment are important. Surgery is the most commonly used method for PDS.
ABSTRACT
Objective To investigate the clinical characteristics and perioperative management of 1aparoscopic cholecystectomy(LC) in the elderly with gallbladder diseases. Methods From January 2006 to December 2016,the clinical data of two hundred and sixteen elderly patients with LC in the Sixth Affiliated People's Hospital of Jinshan Branch were analysed retrospectively. Results The operations of LC were successfully done in 206 patients ( 95. 8%) and 9 cases ( 4. 2%, 9/216 ) underwent conversion to open cholecystectomy for various reasons. Postoperative complications occurred in 22 cases (10. 2%,22/216). 2 cases died within 1 weeks after the operation,and the remaining patients recovered from the hospital. Conclusion Adequate perioperative management,strict surgical indications and operative skills are the necessary conditions for the successful implementation of LC in the elderly.
ABSTRACT
Objective To investigate the methods for prevention and treatment of unexpected hemorrhage during operation of biliary tract.Methods The clinical data of 28 patients with intraoptrative hemorrhage from Jan.2006 to Dec.2016 in our hospital were retrospectively analyzed.Results The cause of introoperative hemorrhage included:iatrogenic biliary injuries in 14 cases (50％),cholelithasis complicated biliary infection in 9 cases (32.1％),bleeding in gall bladder bed in 3 patients (10.7％),and other causes in 2 cases (7.1％).The intraoperative blood loss was 600 to 3000 ml.According to the specific location of bleeding,the amount of blood loss,the cause of bleeding and other conditions,the individual treatment was given.26 were cured and 2 died of hemorrhagic shock and MODS.Conclusions The major causes of hemorrhage during operation of biliary tract comprise iatrogenic biliary injuries,biliary infection,and biliary lithiasis.The reasonable treatment of intraoperative hemorrhage should be based on the concrete bleeding etiologies.
