  • Modified Soave Procedure with Stapler for Treatment of Hirschsprung Disease

    ObjectiveTo explore the clinical value of modified Soave procedure with stapler for the treatment of Hirschsprung disease. MethodsThe clinical data of 26 patients with Hirschsprung disease adimitted in No.477 hospital from January 2002 to December 2010 were analyzed retrospectively. All the patients underwent modified Soave operation with rectal mucosa and proximal intestine stapled end-to-end. ResultsAll operations were successful without anastomotic leakage, aponeurosis of investment infection, and colonitis. Increased stool frequency presented in two cases, which were cured with astringents on day 15 and 30 after operation, respectively. Mild fecal contamination was in one case. All cases were followed up between 3 months to 60 months, with an average 32 months, without incontinence and constiptation. ConclusionModified Soave procedure with stapler is safe and effective for the treatment of Hirschsprung disease in elder children and adult.

  • Comparative Study of Total Parenteral Nutrition and Early Enteral Nutrition in Patients with Gastric Cancer after Total Gastrectomy

      Objective To investigate the influence on the postoperative recovery for giving either total parenteral nutrition (TPN) or early enteral nutrition (EEN) to patients with gastric cancer after total gastrectomy.   Methods Eighty-six patients with gastric cancer undergone total gastrectomy were divided into TPN group (n=31) and EEN group (n=55). Patients in TPN group received TPN support via vena cava (internal jugular vein or subclavian vein), while patients in EEN group received early feeding through the naso-intestinal tube, which was placed during operation, and volume of enteral nutrition (fresubin) was increased daily, full enteral nutrition was expected on day 3-5. Nutrition status after operation, postoperative plasma albumin (Alb), the time of passing gas or stool, the time of oral intake, hospital stay and any postoperative complications were recorded and analyzed.   Results There were no significant differences between two groups (Pgt;0.05) in postoperative plasma Alb level, the time of passing gas or stool, postoperative complications rate or hospital stay. However, in the TPN group, the time of oral intake was shorter than that in EEN group (P=0.004).   Conclusions Both TPN and EEN are the suitable nutritional methods for patients with gastric cancer after total gastrectomy, and with no detectable difference. For patients with high risk, such as severe malnutrition, naso-intestinal tube should be placed for EEN.

  • The measurements of the similarity of dynamic brain functional network

    Brain functional network changes over time along with the process of brain development, disease, and aging. However, most of the available measurements for evaluation of the difference (or similarity) between the individual brain functional networks are for charactering static networks, which do not work with the dynamic characteristics of the brain networks that typically involve a long-span and large-scale evolution over the time. The current study proposes an index for measuring the similarity of dynamic brain networks, named as dynamic network similarity (DNS). It measures the similarity by combining the “evolutional” and “structural” properties of the dynamic network. Four sets of simulated dynamic networks with different evolutional and structural properties (varying amplitude of changes, trend of changes, distribution of connectivity strength, range of connectivity strength) were generated to validate the performance of DNS. In addition, real world imaging datasets, acquired from 13 stroke patients who were treated by transcranial direct current stimulation (tDCS), were used to further validate the proposed method and compared with the traditional similarity measurements that were developed for static network similarity. The results showed that DNS was significantly correlated with the varying amplitude of changes, trend of changes, distribution of connectivity strength and range of connectivity strength of the dynamic networks. DNS was able to appropriately measure the significant similarity of the dynamics of network changes over the time for the patients before and after the tDCS treatments. However, the traditional methods failed, which showed significantly differences between the data before and after the tDCS treatments. The experiment results demonstrate that DNS may robustly measure the similarity of evolutional and structural properties of dynamic networks. The new method appears to be superior to the traditional methods in that the new one is capable of assessing the temporal similarity of dynamic functional imaging data.
