Research advances in the clinical diagnosis and treatment of pheochromocytoma and paranganglioma / 现代泌尿外科杂志

Pheochromocytoma and paranganglioma (PPGL) is a rare neuroendocrine tumor. In recent years, the continuous development of multimodal imaging, pathonomics, genomics, transcriptomics, epigenomics, metabolism and proteomics have provided us with ideas to better understand the complex transfer mechanism of PPGL. This paper will review the precise typing system of PPGL, current research advances in the diagnosis and clinical prognosis.

Research progress of urethral sling in the treatment of male urinary incontinence after prostatectomy / 现代泌尿外科杂志

Stress urinary incontinence (SUI) following prostatectomy is an important and common problem in male, which can significantly reduce the quality of life. Urethral sling is a promising treatment for male SUI. It is easy to operate and can avoid the insertion of prosthesis, making it highly acceptable to patients. In recent years, with the advancement of technology, several kinds of slings have been put into clinical application and have achieved great outcomes. This article reviews the application of urethral sling in the treatment of SUI after prostatectomy.

Effects of dexmedetomidine continuous intravenous infusion on the hemodynamic response of ephedrine and the recovery process of patients undergoing neck surgery under general anesthesia / 中国生化药物杂志

Objective To investigate the effects of dexmedetomidine continuous intravenous infusion on the hemodynamic response of ephedrine and the recovery process of patients undergoing neck surgery under general anesthesia.Methods Select elective fitting line surgery under general anesthesia of 100 patients with cervical disease from January 2015 to December 2015 in the First People's Hospital of Yongkang,randomly divided into low dose group and high dose group, 50 cases in each group, before induction of anesthesia, patients received continuous intravenous pumping of dexmedetomidine 0.4μg/kg in low dose group or 0.8μg/kg in high dose group,after ten mins 0.4μg/kg prior to anesthesia induction,until the end of operation withdrawal;5 min after laryngeal mask insertion, ephedrine 0.1 mg/kg were intravenous administered in two groups.Observe the following indicators:the after entering the operation room ( T0 ) , anesthesia before induction ( T1 ) , after induction ( T2 ) , administration of ephedrine ( T3 ) , the maximum value time(TBP,THR) of heart rate and blood pressure in 10 minutes.Increased of HR,SBP,DBP,recovery related indicators.Results HR, SBP and DBP levels compared no significant difference of T0 with two groups,T1, T2 and T3,HR,SBP, DBP were lower than T0 with two groups(P<0.05),high dose group were lower than low dose group of HR, SBP, DBP(P <0.05);TBP and THR no significant difference of two groups,high dose group were higher than low dose group of Increased of HR,SBP,DBP(P<0.05);high dose group were lower than low dose group of after extubation cough score and sedation agitation score(P<0.05).Spontaneous breathing recovery time and extubation time, called the open time, orientation recovery time,the difference between the two groups was not statistically significant.Conclusion 0.8μg/kg dexmedetomidine continuous intravenous injection of ephedrine in patients with neck pressor effect stronger than the 0.4μg/kg,0.8μg/kg compared with 0.4μg/kg can reduce the recovery period of cough and restlessness,different doses had no effect on recovery.
