Objective To carry out the clinical validation of a domestic HBsAg kit to evaluate its application value. Methods 543 serum samples with HBsAg ELISA values of S/CO ≥ 0. 7 were tested by HBsAg confirmatory test. Specific anti-HBs reagent and control reagent were added separately into duplicate wells of HBsAg ELISA plate, in which test sample was also added. After incubation at 37℃, HBsAg was detected by routine ELISA, and the inhibition rate was calculated using absorbanee (A) result of anti-HBs reagent well and control reagent well according to the provided formula. The sample was confirmed as HBsAg positive when the inhibition rate was≥50%. For HBsAg weakly positive samples, "prolonged confirmatory test" (conjugate reaction time was prolonged to 120 rain) was applied to increase the sensitivity. 39 samples were randomized selected for testing and comparison with Abbott Murex confirmatory test. Results 543 serum samples in total were tested by the confirmatory test. Among the 504 cases which showed positive reaction in screening HBsAg ELISA, 89 ( 17. 7% ) were confirmed as negative. According to their S/CO value of the screening HBsAg test, the ratio of negative cases / tested eases in the group were:S/CO≤<5.0, 87/143 (60. 8% ) ;5.0 < S/CO ≤ 10. 0,0/25 (0) ;10. 0 < S/CO ≤ 15.0, 1/21 (4. 8% ) ;15.0 < S/CO ≤ 20. 0, 1/23 (4. 4% ) ;S/CO 20. 0, 0/292(0). Among 39 cases with negative HBsAg (0. ≤

Objective To study the diagnosis and treatment of synchronous gastric cancer and gastric stromal tumor in 18 cases. Methods Clinical data of 18 cases of synchronous occurrence of gastric cancer and gastric stromal tumor from January 1996 to December 2009 were analyzed retrospectively.Results Clinical features of all cases were atypical. There was 1 case diagnosed preoperatively, 3 cases diagnosed intraoperatively and 14 cases diagnosed postoperatively. The mean size of gastric cancer and gastric stromal tumor was (3.3±2.3) cm and (0.9 ±0.5) cm respectively. There were 16 cases of gastric stromal tumor in low risk of malignance and 2 cases in moderate risk of malignance. All cases were operated without complications and the 1-year, 3-year and 5-year overall survival rate was 88.2%, 63.2% and 36. 1% respectively. Conclusions Clinical features of synchronous occurrence of gastric cancer and gastric stromal tumor are atypical, in this series most gastric stromal tumors are in early stage and of low risk of malignance. The prognosis of patients with synchronous occurrence of gastric cancer and gastric stromal tumor mainly depends on gastric cancer.

Objective To investigate the impact of blood glucose level on the recurrence of liver cancer after laparoscopic surgery. Methods The clinical data of 98 patients with primary hepatocellular carcinoma from January 2012 to January 2015 were retrospectively analyzed. All patients were treated by laparoscopic radical resection of hepatocellular carcinoma. Patients were divided into elevated blood glucose group (n = 23) and control group (n = 75) according to whether the fasting blood glucose was ≥6.1 mmol/L. The recurrence of liver cancer in 1 year and 2 years after operation was compared. The factors influencing the recurrence of liver cancer were analyzed by univariate and multivariate analysis. Results The recurrence rates were 47.82% and 21.33% respectively in the patients with elevated blood glucose and the control group. The recurrence rates were 73.91% and 36.00%respectively in the 2-year postoperative patients with blood glucose and 1 year and 2 years. The recurrence rate was higher than that of the control group, the difference was statistically significant (P < 0.05). Logistic multivariate analysis showed that fasting blood glucose was high, Child-Pugh grade B, intraoperative blood transfusion, lymphatic invasion, high clinical pathology stage, postoperative alpha-fetoprotein (AFP) high, no postoperative adjuvant therapy (P < 0.05). Conclusion The recurrence rate of patients with elevated liver cancer after laparoscopic surgery is high, and fasting blood glucose is high, Child-Pugh grade is B grade, blood transfusion is high, there is lymphatic invasion, high clinical pathology stage after AFP high, no postoperative adjuvant therapy for its postoperative recurrence of risk factors, should strengthen the monitoring of high-risk patients, reduce postoperative recurrence rate.

Objective:To explore the clinical manifestations, diagnosis and treatment methods, and prognosis of acute portal vein thrombosis after hepatectomy.Methods:Retrospective case analysis was used in the case data of 11 patients with acute portal vein thrombosis after hepatectomy, who were treated in Lishui Central Hospital of Zhejiang Province from January 2018 to August 2023, including their demographic characteristics, clinical manifestations, test results, imaging examinations, treatment plans, and prognosis.Results:The diagnostic time of PVT was 4-15 days after surgery. 5 cases were main portal vein thrombosis, including 2 cases who were accumulated splenic vein and superior mesenteric vein, and 6 cases were portal vein branch thrombosis. 2 cases had fever, 3 cases had abdominal distension, 3 cases had ascites, and 5 cases had no obvious clinical symptoms. Patients may experience elevated bilirubin, elevated transaminase, prolonged prothrombin time, and elevated D-2 dimer levels during PVT. 10 cases were diagnosed through CT enhancement, and 1 case was first diagnosed through ultrasound examination. 11 patients who diagnosed with PVT were received anticoagulant therapy, with 6 patients receiving a combination of circulatory improvement drugs. One patient progressed to liver failure, and 10 patients had thrombus disappearance, who were receivedsatisfactory clinical efficacy.Conclusions:Early detections and treatments are the key to treating the acute PVT after hepatectomy. If possible, anticoagulant therapy should be used as soon as possible after surgery. For main grade 3 portal vein thrombosis, early surgical thrombectomy should be considered. At present, there is a lack of effective prevention and prediction methods for acute PVTafter hepatectomy, and thefurther research and exploration are needed.

Objective:To explore the clinical manifestations, diagnosis and treatment methods, and prognosis of hepatic portal venous gas (HPVG).Methods:Retrospective case analysis was used in the case data of 7 patients with HPVG, who were treated in Lishui Central Hospital from January 2017 to July 2024, including 5 males and 2 females. Age ranged from 46 to 90 years, with an average age of 69 years. Abdominal pain was the first manifestation in 6 cases, and septic shock occurred in 2 cases. The initial symptoms, primary diseases, comorbidities, laboratory results, imaging examinations, treatment plans, and prognosis were analyzed. Prognostic follow-up was conducted by telephone, with the focus on whether the patient had experienced HPVG recurrence and postoperative complications. The deadline for follow-up was July 31, 2024.Results:All patients had elevated white blood cells and C-reactive protein (CRP), and prothrombin time was prolonged in 4 patients. pH and base excess decreased in 4 cases, and lactic acid increased in 5 cases. Alanine aminotransferase increased in 2 cases, and total bilirubin increased in 3 cases. Blood culture was positive in 3 cases. Contrast-enhanced abdominal CT showed clear gas shadows in the portal vein and its branches in all 7 cases, which were confined to the left liver in 4 cases and distributed in both sides of the liver in 3 cases. The primary diseases were intestinal obstruction and necrosis in 4 cases, intestinal perforation and necrosis in 1 case, inflammatory bowel disease in 1 case, and acute pancreatitis in 1 case. Five patients were complicated with hypertension, diabetes and other diseases. Two patients received surgical treatment, and the average time from surgery to diagnosis was 6.8 h. Five cases received conservative treatment, 2 cases were cured and 3 cases died, with an average time from onset to death of 21.2 h.Conclusions:Contrast-enhanced abdominal CT should be the preferred method for the diagnosis of HPVG. The primary disease and its severity should be fully evaluated in the treatment of HPVG. Patients with intestinal necrosis should undergo laparotomy as soon as possible, and enterostomy should be performed during the operation. Clinicians should strengthen the awareness of HPVG in order to improve the prognosis of patients.
