ABSTRACT

To investigate the safety and feasibility of longitudinal transpancreatic U-sutures invaginated pancreatojejunostomy (Chen's pancreaticojejunostomy technique) in laparoscopic pancreaticoduodenectomy (LPD). Clinical data of 116 consecutive patients who underwent LPD using Chen's pancreaticojejunostomy technique in Hunan Provincial People's Hospital from May 2017 to December 2018 were retrospectively analyzed. Among these patients, 66 were males and 50 were females. The median age was 58 years old (32-84 yeas old). All 116 patients underwent pure laparoscopic whipple procedure with Child reconstruction method, using Chen's pancreaticojejunostomy technique. The intraoperative and postoperative data of patients were analyzed. All 116 patients underwent LPD successfully. The mean operative time was (260.3±33.5) minutes (200-620 minutes). The mean time of pancreaticojejunostomy was (18.2±7.6) minutes (14-35 minutes). The mean time of hepaticojejunostomy was (14.6±6.3) minutes (10-25 minutes). The mean time of gastrojejunostomy was (12.0±5.5) minutes (8-20 minutes). The mean estimated blood loss was (106.0±87.6) ml (20-800 ml). Postoperative complications were: 11.2%(13/116) of cases had postoperative pancreatic fistula (POPF), including 10.3% (12/116) of biochemical fistula and 0.9%(1/116) of grade B POPF, no grade C POPF occurred; 10.3%(12/116) had gastrojejunal anastomotic bleeding; 3.4%(4/116) had hepaticojejunal anastomotic fistula; 3.4%(4/116) had delayed gastric emptying; 4.3% (5/116) had localized abdominal infection; 12.1%(14/116) had pulmonary infection; postoperative mortality were 0(0/116) and 1.7%(2/116) within 30 days and 90 days, respectively. One patient died of massive abdominal bleeding secondary to Gastroduodenal artery pseudoaneurysm rupture, the other patient died of extensive tumor recurrence and metastasis after surgery. Chen's pancreaticojejunostomy technique is safe and feasible for LPD.It is an option especially for surgeons who have not completed the learning curve of LPD.

ABSTRACT

OBJECTIVE@#To study the role of microRNA-17-5p (miR-17-5p) in the pathogenesis of pediatric nephrotic syndrome (NS) and its effect on renal podocyte apoptosis via the activin A (ActA)/Smads pathway.@*METHODS@#An analysis was performed on 55 children with NS (NS group) who were admitted from March 2018 to March 2019. Fifty healthy children who underwent physical examination during the same period of time were enrolled as the control group. The mRNA expression of miR-17-5p in peripheral blood was measured and compared between the two groups. Human renal podocytes were transfected with antisense oligonucleotide recombinant plasmid containing miR-17-5p (inhibition group) or control vector containing nonsense random sequence (negative control group), and untreated human renal podocytes were used as the blank group. These groups were compared in terms of cell apoptosis and the mRNA and protein expression of miR-17-5p, ActA, and Smads after transfection.@*RESULTS@#The NS group had a significantly higher level of miR-17-5p in peripheral blood than the control group (P<0.001). Compared with the blank and negative control groups, the inhibition group had significantly lower apoptosis rate and relative mRNA expression of miR-17-5p and significantly higher relative mRNA and protein expression of ActA, Smad2, and Smad3 (P<0.001).@*CONCLUSIONS@#There is an increase in the content of miR-17-5p in peripheral blood in children with NS. Low expression of miR-17-5p can inhibit the apoptosis of human renal podocytes, which may be associated with the upregulation of the mRNA and protein expression of ActA, Smad2 and Smad3.

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the changes in the expression levels of peripheral blood T helper 9 (Th9) cells and cytokine interleukin-9 (IL-9) in children in the acute stage of Kawasaki disease (KD) and their clinical significance.</p><p><b>METHODS</b>A total of 45 children in the acute stage of KD who were treated from April 2014 to July 2015 were enrolled, and the children were followed up in the recovery stage. Another 45 healthy children who underwent physical examination were enrolled as the control group. Flow cytometry was used to measure the percentage of peripheral blood Th9 cells, and ELISA was used to measure the serum level of IL-9.</p><p><b>RESULTS</b>The children in the acute stage of KD showed a significantly higher percentage of Th9 cells and a significantly higher serum level of IL-9 compared with those in the recovery stage and the control group (P<0.05). The percentage of Th9 cells and serum level of IL-9 showed no significant differences between the children in the recovery stage and those in the control group (P>0.05). In the acute stage, the percentage of Th9 cells was positively correlated with the levels of IL-9, C-reactive protein (CRP), procalcitonin (PCT), erythrocyte sedimentation rate (ESR), platelet count (PLT), and globulin (r=0.624, 0.324, 0.402, 0.382, 0.467, and 0.386 respectively, all P<0.05), but negatively correlated with serum albumin (r=-0.306, P<0.05). The serum level of IL-9 was positively correlated with the levels of CRP, PCT, ESR, PLT, and globulin (r=0.365, 0.456, 0.403, 0.423, and 0.453 respectively, all P<0.05), but negatively correlated with serum albumin (r=-0.343, P<0.05).</p><p><b>CONCLUSIONS</b>The children in the acute stage of KD show significant increases in the percentage of peripheral Th9 cells and serum cytokine IL-9 level, which return to normal in the recovery stage. In the acute stage of KD, the expression levels of Th9 and IL-9 are closely correlated with laboratory markers. The results suggest that Th9 cells and IL-9 play important roles in the pathogenesis and outcome of KD.</p>
