Objective To understand the status quo of foreign nursing leadership in recent 20 years,and compare and analyze the hotspots and trends of foreign nursing leadership.Methods The bibliometric analysis and cluster analysis were used for analyzing the literature of nursing leadership in PubMed from 1997 to 2006 and from 2007 to 2016,via Bicomb and gCLUTO softwares.Results A total of 482 articles were included.Bibliometric analysis showed that foreign nursing leadership literature number was increasing,which was mainly concentrated in the United States and England.The biclustering analysis showed that the research from 1997 to 2006 focused on patient safety and nursing leadership styles,education and training of nursing leadership,clinical nursing leadership models and nursing quality management;from 2007 to 2016,the research mainly focused on patient safety and nurses' psychological research,clinical nursing leadership theory,clinical nursing practice and competency training,and nnrses' role of leadership research.Conclusion The foreign nursing leadership theory has been developed well for its variety of topics and methods,and the object has been shifted from nursing administrators to clinical nurses.Future research should focus more on application of leadership in clinical nursing,and specialized leadership model and training system may be developed.

Objective:To explore the urodynamic characteristics of bladder function in patients with abnormal urination after radical hysterectomy of cervical cancer.Methods:In a prospective self-controlled study, a total of 84 patients with cervical cancer and clinical stage of ⅠB to ⅡA, meeting the preoperative inclusion criteria in our hospital from January 2016 to June 2018 were enrolled.All patients were tested for urodynamic testing 1 week before and 6 months after surgery.Patient bladder function status was observed and evaluated before and after surgery and urodynamic examination results were analyzed.Results:Of 84 study cases, the 58 patients developed abnormal urination after radical surgery, there were no urination abnormalities in 26 cases.There was no significant difference in age, clinical stage and pathological diagnosis between patients with and without urination abnormalities.Abnormal urination after radical surgery included difficulty in urinating(55%), frequent urination with a feeling of urination not complete(34%), stress urinary incontinence(7%), and urinary incontinence(4%). Among the 26 patients without urination abnormalities after radical surgery, only one case showed an abnormal urodynamic examination(abnormal bladder sensation). In patients without abnormal urination after surgery, differences in the urodynamic examination findings between pre-and post-surgery were not statistically significant(all P> 0.05). At the same time, in all cases of abnormal urination after radical hysterectomy of cervical cancer, 43 patients(74%)with bladder dysfunction had normal urination pattern before operation, but after operation, the urination abnormality required abdominal pressure.Of the patients with bladder dysfunction after surgery, the maximum flow rate(Qmax)was(12.9±10.3)ml/s, the average flow rate(Qave)was(6.0±4.2)ml/s, the voided volume was(148.0±36.8)ml, voiding time was(32.9±22.1)s, maximum flow time was(11.4±5.0)s, postvoid residual urine was(260.2±219.2)ml, maximal detrusor pressure was(12.1±8.9)cmH 2O, bladder compliance was(16.1±4.3)ml/cmH 2O, normal desire to void was(354.5±204.3)ml, maximal capacity was(587.4±152.5)ml, maximum urethral pressure was(97.6±33.1)cmH 2O, maximum urethral closure pressure was(89.9±36.4)cmH 2O, and function urethral length was(29.6±6.5)mm; In comparison, the above indexes-corresponding values at 1 week before surgery were respectively as follows: the Qmax was(25.1±11.4)ml/s, the Qave was(11.4±6.6)ml/s, the voided volume was(318.6±96.4)ml, voiding time was(29.2±18.5)s, maximum flow time was(6.7±3.9)s, postvoid residual urine was(29.9±21.5)ml, maximal detrusor pressure was(31.9±21.4)cmH 2O, bladder compliance was(78.1±33.9)ml/cmH 2O, normal desire to void was(258.2±185.5)ml, maximal capacity was(335.1±124.9)ml, maximum urethral pressure was(96.4±33.9)cm H 2O, maximum urethral closure pressure was(88.5±35.2)cmH 2O, and function urethral length was(37.2±7.2)mm.It can be seen that Qmax, Qave, voided volume, maximum detrusor pressure, bladder compliance, and functional urethral length in patients with abnormal urination are significantly lower after radical hysterectomy of cervical cancer than before the surgery.While, normal desire to void, maximum capacity, maximum flow time, and postvoid residual urine volume were higher after radical hysterectomy than before surgery( P<0.05). In addition, there was no significant difference in voiding time, maximum urethral pressure and maximum urethral closure pressure between pre-and post-operation.Besides, it is worth noting that there was no significant difference in preoperative urodynamic test results between patients without abnormal urination versus patients with abnormal urination( P>0.05), and the difference in urodynamic test results between the two groups is statistically significant( P<0.05). There was no statistically significant difference in abnormal urination and in urodynamic test results between different clinical stages and between different pathological types( P>0.05). Conclusions:The characteristics of urinary dynamics in patients with abnormal urination after radical hysterectomy of cervical cancer are mainly manifested as decreased bladder sensory function and abnormal detrusor function.And the urodynamic test can provide objective clinical indicators for early diagnosis.
