This study aimed to compare the effectiveness between TIPS and OSED for the treatment of PHRVB.METHODS: The data were retrospectively retrieved from 479 cirrhotic patients(Child-Pugh A or B class) with PHRVB, who had undergone TIPS(TIPS group) or OSED(OSED group) between January 1, 2010 and October 31, 2014.RESULTS: A total of 196 patients received TIPS, whereas 283 underwent OSED. Within one month after TIPS and OSED, the rebleeding rates were 6.1% and 3.2%, respectively(P=0.122). Significantly lower incidence of pleural effusion,splenic vein thrombosis, and pulmonary infection, as well as higher hepatic encephalopathy rate, shorter postoperative length of hospital stay, and higher hospital costs were observed in the TIPS group than those in the OSED group. During the follow-up periods(29 months), significantly higher incidences of rebleeding(15.3% vs 4.6%, P=0.001) and hepatic encephalopathy(17.3% vs 3.9%, P=0.001) were observed in the TIPS group than in the OSED group. The incidence of instent stenosis was 18.9%. The survival rates were 91.3% in the TIPS group and 95.1% in the OSED group. The long-term liver function did not worsen after either TIPS or OSED.CONCLUSION: For the patients with liver function in the Child-Pugh A or B class, TIPS is not superior over OSED in terms of PHRVB treatment and rebleeding prevention.展开更多

Complications associated with predictors were analyzed.RESULTS: The postoperative mortality rate was 16%(53/334). Up to 31% of patients were successfully treated with percutaneous catheter drainage alone. The rates of intra-abdominal bleeding, colonic fistula, and progressive infection were 15 %( 50 / 334), 20%(68/334), and 26%(87/334), respectively. Multivariate analysis indicated that Marshall score upon admission, multiple organ failure, preoperative respiratory infection, and sepsis were the predictors of postoperative progressive infection(P < 0.05). Single organ failure, systemic inflammatory response syndrome upon admission, and C-reactive protein level upon admission were the risk factors of postoperative colonic fistula(P < 0.05). Moreover, preoperative Marshall score, organ failure, sepsis, and preoperative systemic inflammatory response syndrome were the risk factors of postoperative intra-abdominal bleeding(P < 0.05).CONCLUSION: Marshall score, organ failures, preoperative respiratory infection, sepsis, preoperative systemic inflammatory response syndrome, and C-reactive protein level upon admission are associated with postoperative complications.展开更多

METHODS: Thirty Sprague-Dawley (SD) rats were randomized into control group, AP group and CQCQD group (n = 3 × 10). The rats in the CQCQD group were intragastrically administered with CQCQD (10 mL/kg every 2 h) after induction of AP by intraperitoneal injection of caerulein (50 μg/kg.h × 5) within 4 h. At 6 h after the induction of AP model, pancreatic tissues were collected for the pathological observation, mRNA extraction for determination of SERCA1 and SERCA2 mRNA expression or pancreatic acinar cell isolation for measurement of fluorescence intensity (FI) of intracellular calcium ion concentration [Ca2+]i. RESULTS: There was no expression of pancreatic SERCA1 mRNA in the control group and the AP group. The expression of pancreatic SERCA2 mRNA in the AP group was down-regulated (expression ratio = 0.536; P = 0.001) compared with the control group, while that in the CQCQD group was up-regulated (expression ratio= 2.00; P = 0.012) compared with AP group. The FI of intracellular [Ca2+] of pancreatic acinar cells in the AP group (138.2 ± 23.1) was higher than the C group (111.0 ± 18.4) and the CQCQD group (118.7 ± 15.2 ) (P < 0.05) and the pancreatic pathological score in the CQCQD group was lower than that in the AP group (5.7 ± 1.9 vs 9.2 ± 2.7, P < 0.05).CONCLUSION: CQCQD can up-regulate the expression of SERCA2 mRNA of pancreatic tissues, reduce intracellular calcium overload and relieve pancreatic tissue lesions.展开更多

METHODS: Eighty patients with SAP were randomized and received 100 mL/d of 20% AGD intravenously for 10 d starting either on the day of (early treatment group) or 5 d after (late treatment group) admission. Groups had similar demographics, underlying diseases, Ranson score, Acute Physiology and Chronic Health Evaluation Ⅱ (APACHE Ⅱ) score, and Balthazar’s computed tomography (CT) score at the beginning of the study and underwent similar other medical and nutritional management. RESULTS: The duration of acute respiratory distress syndrome (2.7 ± 3.3 d vs 12.7 ± 21.0 d, P < 0.01), renal failure (1.3 ± 0.5 d vs 5.3 ± 7.3 d, P < 0.01), acute hepatitis (3.2 ± 2.3 d vs 7.0 ± 7.1 d, P < 0.01), shock (1.7 ± 0.4 d vs 4.8 ± 3.1 d, P < 0.05), encephalopathy (2.3 ± 1.9 d vs 9.5 ± 11.0 d, P < 0.01) and enteroparalysis (2.2 ± 1.4 d vs 3.5 ± 2.2 d, P < 0.01) and hospital stay (28.8 ± 9.4 d vs 45.2 ± 27.1 d, P < 0.01) were shorter in the early treatment group than in the late treatment group. The 15-d APACHE Ⅱ score was lower in the early treatment group than in the late treatment group (5.0 ± 2.4 vs 8.6 ± 3.6, P < 0.01). The infection rate (7.9% vs 26.3%, P < 0.05), operation rate (13.2% vs 34.2%, P < 0.05) and mortality (5.3% vs 21.1%, P < 0.05) in the early treatment group were lower than in the late treatment group.CONCLUSION: Early treatment with AGD achieved a better clinical outcome in SAP patients.展开更多
