OBJECTIVE To investigate the influence of single-port laparoscopic percutaneous extraperitoneal closure (LPEC) on the orientation of the vas deferens and testicular perfusion and volume in pediatric patients undergoing inguinal hernia repair. METHODS A total of 92 consecutively enrolled boys preoperatively diagnosed with a unilateral inguinal hernia(More)
Hypertrophic scar is a common dermal disease. Numerous treatments are currently available but they do not always yield excellent therapeutic results. Hence, alternatives are needed. Recent basic and clinical research has shown that botulinum toxin type A (BTXA) has antihypertrophic scar properties but the molecular mechanism for this action is unknown. The(More)
OBJECTIVE To report our 5-year experience with a modified single-port, double-needle, minilaparoscopic technique for patent processus vaginalis with multiple peritoneal folds in the hydrocele sac orifice. METHODS A total of 125 consecutive cases of boys with unilateral pediatric hydrocele underwent minilaparoscopic repair between June 2008 and June 2013.(More)
China is experiencing a high speed economic development which may exert great pressure on the environment and energy systems. To measure the environmental and energy performance during the economic development process, this paper selected 30 provinces, cities or autonomous regions as the decision making unit (DMU), and proposed a Green GDP index (GGI) in(More)
The rapid growth of transport requirements in China will incur increasing transport energy demands and associated environmental pressures. In this paper, we employ a generalized data envelopment analysis (DEA) to evaluate the relative energy efficiency of rail, road, aviation and water transport from 1971 to 2011 by considering the energy input and(More)
BACKGROUND This retrospective study aimed to evaluate the long-term results of two kinds of surgical atrial fibrillation radiofrequency ablations in concomitant cardiac operations. METHODS We enrolled 129 patients from January 2006 to December 2015 and performed cardiac operations concomitantly with surgical atrial fibrillation. The patients were divided(More)
INTRODUCTION This study aimed to assess the effects of different temperature settings of hypothermic circulatory arrest (HCA) on intestinal barrier function in a piglet model. METHODS Twenty Wuzhishan piglets were randomly assigned to 40 min of HCA at 18°C (DHCA group, n = 5), 40 min of HCA at 24°C (MHCA group, n = 5), normothermic cardiopulmonary bypass(More)
Pressure vessels are widely used in industrial fields, and some of them are safety-critical components in the system-for example, those which contain flammable or explosive material. Therefore, the pressure of these vessels becomes one of the critical measurements for operational management. In the paper, we introduce a new approach to the design of(More)
BACKGROUND This study aimed to study the feasibility, efficacy and safety of using laryngeal mask (LM) ventilation compared with endotracheal intubation (ETI) during neonatal resuscitation. METHODS Neonates with a heart rate below 60 beats per minute despite 30 s of face mask ventilation were assigned quasi-randomly (odd/even birth date) to LM (n = 36) or(More)
