Objective To explore the relationship between gut mucosal barrier dysfunction and immune response in patients with early severe acute pancreatitis (SAP).Method 46 patients with early SAP were enrolled into this study from January 2010 to December 2012.Results The levels of endotoxin,the lactulose/mannitol (L/M) ratio,the D (-)-lactate concentration,and the proportion of HLA-DR-positive monocytes all decreased from a high level,while the frequency of Tregs increased during the first 14 days.The Th1/Th2 ratio decreased,with a decreased Th1 and an increased Th2 profile in the first week,but it subsequently increased,with an increased Th1 profile.Conclusions The data from this study showed that immunosuppression and immune imbalance happened in patients with early SAP,and showed a positive relationship with gut mucosal barrier dysfunction in patients with early SAP.Thus,early protection of the function of intestinal mucosal barrier is important in the treatment of SAP.

Objective Hepatic artery (HA) reconstruction is one challenging procedure in pediatric liver transplantation (PLT).Here we review the first 115 microsurgical reconstructions of HA in PLT performed by a single surgeon,aiming to demonstrate the learning curve and the problems encountered.Methods From July 2016 to January 2017,a series of 115 microsurgical reconstructions of HA in PLT for end-stage liver disease were finished by one single surgeon with 4-year liver surgery experience and 2-week microsurgical training.HA reconstruction was performed with an operating microscope (Carl-Zeiss S88).Reconstruction was completed with interrupted sutures with 8-0 or 9-0 Prolene using the double clip for fixation.The blood flow was examined by Doppler scan daily after PLTs in first week and then once in 2nd week and first month for patency.A total of 143 artery anastomoses were performed in 115 PLTs.The age ranged from 3 months to 9 years.Indications for PLT included biliary atresia (105/115),Alagille syndrome (5/115),PFIC (3/115),Caroli disease (1/115),methylmalonicacidemia (1/115) and glycogen storage disease (1/115).Most of the PLTs were living donor liver transplantation (107/115),along with OLT (5/115) and split LT (3/115).Results The diameter of the arteries was mostly less than 2 mm (98/115).Up to date,one HA thrombosis (HAT) occurred at D8 after LT and 4 cases suspected as temporal HA stenosis (HAS) around 2 weeks after LT,which manifested as low velocity (<20 cm/s) and resistance index (<0.50) by Doppler.The HAT case failed in emergent re-anastomosis,but had a spontaneous recanalization at 3 weeks and is now in good condition without biliary problem.All the HAS children recovered to normal flows at first month.All children with HA complications started warfarin upon detection,with a targeted INR between 1.5-2.0.There were 6 deaths in this series including 5 cases of infections and 1 case of graft failure.Learning curve suggested a two phases growth (first 44 cases practicing phase vs.next 71 cases mature phase),which can be attributed to experience accumulation in terms of precise of manipulation,choice of inflow arteries for better match and stronger pulsation,avoidance of length redundant,prevention of kink.All the HAT and HASs happened in practicing phase while outcomes were excellent in mature phase.Moreover,time for each anastomosis was significantly shortened in second phase from 45-70 min to 30-55 min.Conclusion Microsurgical technique is highly safe in pediatric HA reconstruction,especially for very tiny arteries.It is possible to achieve low risk of complications for a new surgeon with adequate experience in liver surgery and microsurgical training.However,more surveillance and timing anticoagulation therapy is required before the mature of microsurgical technique.

Objective To evaluate the role of gamma curve fitting technique of contrast-enhanced ultrasound in quantitative analysis of microcirculation in renal solid lesions. Methods A total of fifty patients with renal parenchyma solid lesions were performed contrast-enhanced ultrasound. The images were analysed by computer with gamma fitting analysis of contrast-enhanced ultrasonic system. The quantitative parameters were obtained by the time-intensity curves, such as ascending slope (a3), descending slope (a2), arrival time (AT), time to peak intensity (TTP), basic intensity (BI), peak intensity, amplification (AMP), area under the curve (AUC), mean transit time (MTT) and perfusion index (PI). The parameters were compared between renal malignant and benign solid lesions. Results Fast-in and fast-out was the main perfusion mode in renal malignant tumors while slow-in and slow-out was found in renal angiomyolipoma (AML). The perfusion modes in renal malignant tumors and renal AML were fast-in and fast-out in 28 cases and 0 case, fast-in and slow-out in 4 cases and 1 case, slow-in and fast-out in 5 cases and 1 case, and slow-in and slow-out in 1 case and 10 cases, respectively. There were significant differences in the quantitative parameters such as a2, AUC and PI between renal malignant tumors and renal AML obtained by the time-intensity curves (P<0.05). Conclusion Gamma fitting analysis of contrast-enhanced ultrasound system can provide quantitative information of microcirculation of renal tumors, which helps to differentiate benign renal tumors from malignant ones.
