Efficacy and safety of the Jinling procedure in the treatment of adult Hirschsprung disease / 中华胃肠外科杂志

<p><b>OBJECTIVE</b>To investigate the safety, efficacy and long-term outcomes of Jinling procedure in the treatment of adult Hirschsprung disease.</p><p><b>METHODS</b>Clinical and follow-up data of 125 patients with adult Hirschsprung disease undergoing Jinling procedure at the Department of General Surgery between January 2000 and January 2013 were summarized. All the patients were diagnosed by CT, barium enema, anorectal pressure detection and pathology examination. Abdominal symptoms, gastrointestinal quality of life index(GIQLI, the lower score, the worse quality of life), Wexner constipation score (higher score indicated worse symptom), defecography (evaluation included rectocele, mucosal prolapse, intramucosal intussusception, perineal prolapse) and other operative complications were compared before and after operation.</p><p><b>RESULTS</b>Among 125 patients, 69 were male and 56 were female with median age of (41.2±15.5) (18 to 75) years. The follow-up rates were 94.4%(118/125), 92.0%(115/125), 89.6%(112/125) and 88.0%(110/125) at postoperative months 1, 3, 6, and 12. Incidences of abdominal distension and abdominal pain were 100% and 82.4%(103/125) before operation, and were 7.3%(8/110) and 20.9%(23/110) at 12 months after surgery. Wexner score was significantly lower at postoperative months 1(8.7±2.9), 3 (7.2±2.8), 6(6.7±2.2) and 12(6.3±1.7) than that before operation (21.4±7.2) (P<0.01). GIQLI score was 51.6±11.9 before operation, though it decreased at 1 month (47.3±5.5)(P<0.05) after surgery, but increased significantly at postoperative months 3, 6, 12(68.9±8.0, 96.5±8.2, 103.2±8.6)(P<0.01). Abnormal rate of defecography was 70.4%(81/115), 48.2%(54/112) and 27.3%(30/110) at postoperative months 3, 6, 12, which was significantly lower than 91.2%(114/125) before operation (P<0.01). Morbidity of postoperative complication was 29.6%(37/125), including 5 cases of surgical site infection (4.0%), 2 of anastomotic bleeding (1.6%), 8 of anastomotic leakage (6.4%, one died of severe abdominal infection), 4 of urinary retention (3.2%), 3 of recurrent constipation (2.4%, without megacolon relapse), 11 of bowel obstruction (8.8%), 2 of anastomotic stricture(1.6%) and 2 of refractory staphylococcus aureus enteritis (1.6%, diagnosed by stool smear and culture, and both died finally).</p><p><b>CONCLUSION</b>Jinling procedure is a safe and effective surgical procedure for adult Hirschsprung's disease.</p>

Breviscapine ameliorates cardiac dysfunction and regulates the myocardial Ca(2+)-cycling proteins in streptozotocin-induced diabetic rats.

To investigate the influence of breviscapine on the cardiac structure and function in diabetic cardiomyopathy rats as well as the expression of protein kinase C (PKC) and Ca(2+)-cycling proteins expression. Diabetes was induced in male Sprague-Dawley rats by a single intraperitoneal injection of streptozotocin and the control rats were injected with saline. After the induction of diabetes for 4 weeks, the animals were divided into different groups: (1) normal rats as control; (2) diabetic rats; (3) diabetic rats with administration of breviscapine (10 or 25 mg kg(-1) day(-2)). After treatment with breviscapine for 6 weeks, the invasive cardiac function and echocardiographic parameters were measured, and heart tissue was obtained for electron microscope study. The expression of protein kinase C (PKC) and calcium handling regulators, such as protein phosphatase inhibitor-1 (PPI-1), phospholamban (PLB) and Ca(2+)-ATPase (SERCA-2), ryanodine receptor (RyR) were detected by western blot or RT-PCR. The activity of SERCA-2 was measured using Ca(2+)-ATPase kit. Diabetic rats showed impaired cardiac structure and function compared with control rats. The expression of PKC, PLB increased significantly, while the PPI-1, SERCA-2 and RyR expression decreased. Treatment with breviscapine could reverse the cardiac dysfunction and structure changes in diabetic cardiomyopathy rats, and decrease the expression of PKC and PLB, as well as increase the expression of PPI-1, SERCA-2 and RyR. The protective effect of breviscapine was dose related. This study showed that breviscapine could regulate the expression of PKC, PPI-1, PLB and SERCA-2 and have protective effect on diabetic cardiomyopathy.
