Objective To discuss the feasibility,safety and surgical effect of the modified Prolene thread double-headed needle"U-shaped"suture combined with extra-and intracavity combination knotting method in thoracoscopic diaphragm plication in the treatment of diaphragmatic eventration in infants.Methods A retrospective analysis was conducted on clinical data of 70 infants who underwent thoracoscopic diaphragm plication in the treatment of diaphragmatic eventration in our hospital from May 2010 to May 2022.According to the different methods of suturing and knotting,the patients were divided into the improved group(modified Prolene thread double-headed needle"U-shaped"suture combined with extra-and intracavity combination knotting method,n =30)and the conventional group(intracavity suture knotting method,n = 40).The perioperative indicators,as well as whether there was knot loosening or recurrence of diaphragmatic eventration,were compared between the two groups.Results All the 70 operations were performed safely and successfully,without conversion to open surgery.The operation time in the improved group was significantly less than that in the conventional group[(35.3±7.4)min vs.(64.7±10.8)min,t =13.521,P =0.000].There were no statistically significant differences between the two groups in terms of intraoperative bleeding volume,indwelling time of thoracic drainage tube,postoperative hospital stay,preoperative,intraoperative,and postoperative pH values,PO2,and PCO2 in arterial blood gas,and postoperative slight diaphragm elevation(P>0.05).All the 70 cases were followed up for 6-24 months postoperatively,with a median follow-up time of 12 months,having no knot loosening or recurrence of diaphragmatic eventration.No death was reported.Conclusions The modified Prolene thread double-headed needle"U-shaped"suture combined with extra-and intracavity combination knotting method in thoracoscopic diaphragm plication in the treatment of diaphragmatic eventration in infants is safe,feasible,effective,and easy to operate.Doctors with a certain endoscopic surgery experience can master it quickly,which is suitable for promotion in qualified hospitals.

The nucleus accumbens (NAc) plays an important role in various emotional and motivational behaviors that rely on heightened wakefulness. However, the neural mechanisms underlying the relationship between arousal and emotion regulation in NAc remain unclear. Here, we investigated the roles of a specific subset of inhibitory corticotropin-releasing hormone neurons in the NAc (NAc^CRH) in regulating arousal and emotional behaviors in mice. We found an increased activity of NAc^CRH neurons during wakefulness and rewarding stimulation. Activation of NAc^CRH neurons converts NREM or REM sleep to wakefulness, while inhibition of these neurons attenuates wakefulness. Remarkably, activation of NAc^CRH neurons induces a place preference response (PPR) and decreased basal anxiety level, whereas their inactivation induces a place aversion response and anxious state. NAc^CRH neurons are identified as the major NAc projection neurons to the bed nucleus of the stria terminalis (BNST). Furthermore, activation of the NAc^CRH-BNST pathway similarly induced wakefulness and positive emotional behaviors. Taken together, we identified a basal forebrain CRH pathway that promotes the arousal associated with positive affective states.

Objective To understand the current cognition status of stroke rehabilitation nursing knowledge in young nurses of the department of neurology.Methods Self-designed questionnaires were used for investigating 273 young nurses between 20 and 30 years old of the department of neurology of 4 tertiary hospitals in Zhengzhou.Results The current status of stroke rehabilitation nursing knowledge of the nurses surveyed was generally at a low level.There were no significant differences among nurses with different education degrees,professional titles and whether their relatives suffered from stroke.However,there were significant differences among nurses with different professional lives and whether the department carried out rehabilitation care.Conclusions Nursing educators and managers need to find a new way to improve the level of stroke rehabilitation nursing knowledge of the young nurses.
