Objective:To explore the current status of quality of pediatric nurses ′ leader-member exchange, recovery experience, thriving at work, as well as to explore the correlation between leader-member exchange, recovery experience, and thriving at work. Methods:A convenience sampling method was used to select 312 pediatric nurses from four tertiary level A hospitals in Qingdao from September to November 2021 as the study population. A cross-sectional survey was conducted using the Leader-Member Exchange Scale, the Recovery Experience Scale, and the Thriving at work Scale. Descriptive statistical analysis, Pearson correlation analysis, and structural equation modeling were conducted on the data to analyze the mediating effect of recovery experience between leader-member exchange and thriving at work, and Bootstrap method was applied to validate the mediating effect.Results:The pediatric nurses ′ leader-member exchange score was (3.94 ± 0.90) points, recovery experience score was (3.47 ± 0.76) points, and thriving at work score was (3.71 ± 0.75) points. Leader-member exchange was positively correlated with recovery experience and thriving at work ( r=0.486, 0.575, both P<0.01); recovery experience was positively correlated with thriving at work ( r=0.711, P<0.01); the test of mediating effect showed that recovery experience partially mediated the effect between leader-member exchange and thriving at work, intermediary effect accounted for 66.9% of the total effect. Conclusions:Pediatric nurses have moderate levels of leader-member exchange, recovery experience, thriving at work. Leader-member exchange can affect pediatric nurses ′ thriving at work both directly and indirectly through the recovery experience. Nursing managers should strengthen the management of relationships with nurses, form good psychological and emotional bonds, and conduct recovery experience training to improve nurses ′ thriving at work, and improve the quality of care.

Objective:In order to explore the impact of corona virus disease 2019(COVID-19)on the hospitalization of children with bronchiolitis and to improve clinicians′ understanding of the characteristics of bronchiolitis during the COVID-19 epidemic.Methods:This was a multicenter clinical study, and the data have been collected from 23 children′s medical centers in China.All the clinical data were retrospectively collected from children with bronchiolitis who were hospitalized at each study center from January 1, 2019 to December 31, 2021.The results included gender, age at hospitalization, length of stay, respiratory syncytial virus(RSV) test results, severity rating, ICU treatment, and the total number of children hospitalized with respiratory tract infection during the same period.The clinical data of children with bronchiolitis in 2019 before COVID-19 epidemic and in 2020、2021 during COVID-19 epidemic were statistically analyzed and compared.Results:According to a summary of data provided by 23 children′s medical centers, there were 4 909 cases of bronchiolitis in 2019, 2 654 cases in 2020, and 3 500 cases in 2021.Compared with 2019, the number of bronchiolitis cases decreased by 45.94% in 2020 and 28.70% in 2021.In 2019, 2020 and 2021, there were no significant differences in gender ratio, age, and duration of hospitalization.Compared with 2019, the ratio of bronchiolitis to the total number of hospitalizations for respiratory tract infection decreased significantly in 2020 and 2021( χ2=12.762, P<0.05; χ2=84.845, P<0.05).The proportion of moderate to severe bronchiolitis cases in both 2020 and 2021 was lower than that in 2019, and the difference was statistically significant ( χ2=4.054, P<0.05; χ2=8.109, P<0.05).There was no statistically significant difference in the proportion of bronchiolitis cases requiring ICU treatment between 2019, 2020, and 2021 ( χ2=1.914, P>0.05).In 2019, a total of 52.60%(2 582/4 909) of children with bronchiolitis underwent RSV pathogen testing, and among them, there were 708 cases with RSV positive, accounting for 28.00%.In 2020, 54.14%(1 437/2 654) of children with bronchiolitis underwent RSV pathogen testing, and there were 403 cases with RSV positive, accounting for 28.04%.In 2021, 66.80%(2 238/3 500) of children with bronchiolitis underwent RSV pathogen testing, and there were 935 cases with RSV positive, accounting for 41.78%.Compared with 2019 and 2020, the RSV positive rate in 2021 showed a significant increase( χ2=99.673, P<0.05; χ2=71.292, P<0.05). Conclusion:During the COVID-19 epidemic, the implementation of epidemic prevention and control measures reduced the hospitalization rate and severity of bronchiolitis, but did not reduce the positive rate of RSV detection.

Objective:To assess the efficacy and safety of 100 units of botulinum toxin A (BTX-A) intradetrusor injection in patients with overactive bladder.Methods:From April 2016 to December 2018, 17 tertiary hospitals were selected to participate in this prospective, multicenter, randomized, double-blind, placebo-controlled study. Two phases of study were conducted: the primary phase and the extended phase. This study enrolled patients aged 18 to 75 years who had been inadequately managed by anticholinergic therapy (insufficient efficacy or intolerable side effects) and had spontaneous voiding with overactive bladder. Exclusion criteria included patients with severe cardiac, renal and hepatic disorders, patients with previous botulinum toxin treatment for 6 months or allergic to BTX-A, patients with urinary tract infections, patients with urinary stones, urinary tract tumors, diabetes mellitus, and bleeding tendency. Eligible patients were randomly assigned to BTX-A group and placebo control group in a ratio of 2∶1. Two groups of patients received 20 intradetrusor injections of BTX-A 100U or placebo at the depth of the submucosal muscle layer respectively under cystoscope, including 5 injections at the base of the bladder, 3 injections to the bladder triangle, 5 injections each to the left and right walls and 2 injections to the top, sparing the bladder neck. As a placebo control group, patients received same volume of placebo containing no BTX-A and only adjuvant freeze-dried preparations for injection with the same method. A combination of gelatin, sucrose, and dextran served as adjuvants. Average micturition times per 24 hours, urinary incontinence (UI) episodes per day, average micturition volume per day, OAB symptom score(OABSS), and quality of life (QOL) score were recorded at baseline and the 2nd, 6th and 12th week after treatment. The primary efficacy endpoint was the change from baseline in the average micturition times per 24 hours at the 6th week after treatment. The secondary efficacy endpoints included the change from baseline in the average micturition times per 24 hours at 2nd and 12th week, as well as the change from baseline in the OABSS, QOL score, average frequency of urgency and UI episodes per day, urgency score, average micturition volume per day at 2nd, 6th and 12th week after treatment. Patients were followed for 12 weeks to assess adverse events (AEs). After assessed at week 12, if the micturition times has decreased less than 50% compared to baseline and the patient is willing to receive retreatment, then patients could enter the extended trial phase. In that phase, patients in both groups were injected with 100 units BTX-A from 12th week onwards and then followed up the same indicators for 12 weeks.Results:216 patients were enrolled in this trial (144 cases in the BTX-A group and 72 cases in the placebo control group). Baseline characteristics such as age (47.75±14.20 in the BTX-A group and 46.39±15.55 in the control group), sex (25 male/117 female in the BTX-A group and 10/61 in the control group), and disease duration (0.51 years in the BTX-A group and 0.60 years in the control group) were balanced between the two groups( P>0.05). A marked reduction from baseline in average micturition times per 24 hours was observed in all treatment groups at the 6th week and the reduction of the two groups was statistically different ( P<0.001 and P=0.008 respectively). Compared with the baseline, the average micturition times per 24 hours at the 6th week decreased from baseline by 2.40(0.70, 4.60)times for the BTX-A group and 0.70(-1.00, 3.30) times for the placebo control group respectively, and the difference between the two groups was considered to be statistically significant ( P=0.003). The change rates of average micturition times per 24 hours from baseline at the 6th week of the two groups were (16±22)% and (8±25)% respectively, and the difference between the two groups was statistically significant ( P=0.014). Compared with the baseline, the average micturition times per 24 hours at 2nd and 12th week decreased by 2.00(0.00, 4.00)and 3.30(0.60, 5.03)for the BTX-A group, 1.00(-1.00, 3.00)and 1.70(-1.45, 3.85)for the placebo control group respectively. The difference between two groups was considered to be statistically significant ( P=0.038 and P=0.012); the changes of average urgency times per day for the BTX-A group and the control group at the 2nd, 6th and 12th week were 2.00(0.00, 4.30)and 2.40(0.30, 5.00), 3.00(0.30, 5.70)and 0.70(-1.30, 2.70), 0.70(-1.30, 3.00) and 1.35(-1.15, 3.50), respectively. There were significant differences between two groups at the 2nd, 6th and 12th week, ( P=0.010, P=0.003 and P=0.025, respectively). The OABSS of the BTX-A group and the control group at the 6th week decreased by 1.00(0.00, 4.00)and 0.50(-1.00, 2.00) compared with the baseline, and the difference between the two groups was statistically significant ( P=0.003). 47 cases of BTX-A group and 34 cases of placebo control group entered the extended trial phase, and 40 and 28 cases completed the extended trial phase, respectively. The average micturition volume per 24 hours changed by -16.60(-41.60, -0.60)ml and -6.40(-22.40, 13.30)ml, (-35.67±54.41)ml and(-1.76±48.69)ml, (-36.14±41.51)ml and (-9.28±44.59)ml, (-35.85±43.35)ml and(-10.41±40.29)ml for two groups at the 12th, 14th, 18th and 24th week, and the difference between two groups was statistically significant at each follow-up time ( P=0.01, 0.006, 0.012 and 0.016, respectively). There was no significant difference in other parameters( P>0.05). However, adverse reactions after intradetrusor injection included increased residual urine volume (27 in the BTX-A group and 3 in the control group), dysuria (21 in the BTX-A group and 6 in the control group), urinary infection (19 in the BTX-A group and 6 in the control group), bladder neck obstruction (3 in the BTX-A group and 0 in the control group), hematuria (3 in the BTX-A group and 1 in the control group), elevated alanine aminotransferase (3 in the BTX-A group and 0 in the control group), etc. During the follow-up period, there was no significant difference in the other adverse events between two groups except the increase of residual urine volume( P<0.05). In the primary trial phase, among the 27 cases with increased residual urine volume in BTA group, only 1 case (3.70%) with PVR more than 300 ml; the PVR of 3 patients in the placebo group was less than 100 ml. The increase of residual urine volume caused by the injection could be improved or disappeared with the passage of time. Conclusions:Intradetrusor injection of Chinese BTX-A improved the average micturition times per 24 hours, the average daily urgent micturition times, OABSS, and average micturition volume per time, and reduced the adverse effects in patients with overactive bladder.Chinese BTX-A at dose of 100U demonstrated durable efficacy and safety in the management of overactive bladder.

Objective:To investigate the risk factors for prolonged acute post-streptococcal glomerulonephritis(APSGN) in children, and to provide evidence for the prevention and treatment of chronic kidney diseases in children.Methods:A retrospective analysis was performed on the patients who were diagnosed as APSGN and hospitalized in the Department of Nephrology and Rheumatology of Hunan Children′s Hospital from January 2005 to August 2017 with complete clinical data, and follow-up time of more than 12 months.The patients were divided into the non-prolonged group and the prolonged group according to whether the disease course of the children exceeded 1 year. Logistic regression analysis of the high-risk factors for the prolonged disease was conducted. Results:Among 271 children included in the study, 197 cases were males, 74 cases were females; with the median age of 9.91 (7.66, 11.33) years old; there were 154 cases in the non-prolonged group (course of disease < 1 year) and 117 patients in the prolonged group (course of disease ≥1 year). Logistic regression analysis showed that duration of proteinuria ≥8 weeks, acute kidney injury, a large amount of proteinuria, and female were the risk factors for the prolonged APSGN (all P<0.05). Giving 1 point to the acute kidney injury duration of proteinuria ≥8 weeks and female, and 2 points to a large amount of proteinuria, the receiver operating characteristic curve analysis showed that for patient whose risk score was 3 points or more, the sensitivity of APSGN to be belonged was 43.6%, specificity was 86.4%, and positive predictive value and negative predictive value were 70.8% and 66.8%. Conclusions:Patients with a large amount of proteinuria accompanied by acute kidney injury or proteinuria duration ≥8 weeks, or female patients with a large amount of proteinuria, or female patients with acute kidney injury and proteinuria duration ≥8 weeks, but without a large amount of proteinuria, have a higher risk of prolonged APSGN.

OBJECTIVE: To explore the influence of negative emotion on the professional identity of nurses in Guangdong Province and the moderating role of social support during COVID-19 pandemic. METHODS: A convenience sampling method was used to select 436 nurses in Guangdong Province as study subjects. The Depression-Anxiety-Stress Scale, Nurse Professional Identity Scale and Perceived Social Support Scale were used to investigate the negative emotion, professional identity and social support of these nurses. RESULTS: The median, the 25 th and 75 th percentile scores of the negative emotion total scores of nurses was 10.0(3.0,17.8). The total scores of professional identity and social support were(106.6±16.9) and(56.9±13.2), respectively. The professional identity and social support were negatively correlated with negative emotion(P<0.01), while the professional identity was positively correlated with social support in these nurses(P<0.01). The negative emotion of nurses can negatively predict their professional identity, and social support plays a moderating role in it.CONCLUSION: The higher the degree of social support, the less negative emotional impact on professional identity of nurses during COVID-19 pandemic. Nurses should be given more social supports.

Objective:To evaluate the diagnostic efficacies of computed tomography (CT), clinical manifestations and 2019 novel coronavirus (2019-nCoV) nucleic acid test results for the screening and diagnosis of novel coronavirus pneumonia.Methods:The clinical data of suspected cases with corona virus disease 2019 (COVID-19) visited fever clinic or stayed in emergency room of the First Affiliated Hospital of Nanchang University from January 23 to February 9, 2020 were collected. Totally 274 cases who met the inclusion criteria were enrolled. Four screening schemes including chest CT screening, scoring, chest CT and scoring series screening, chest CT and scoring parallel screening were designed. The statistical analysis was performed by using chi-square test. The sensitivities, specificities and the areas under the receiver operator characteristic curve of the four screening schemes were calculated, and the diagnostic efficacies were evaluated.Results:Among the 274 cases, 93.80%(257/274) presented with typical clinical symptoms, 47.81%(131/274) had epidemiological history, and the blood routine examination results of 45.26%(124/274) cases met the positive criteria of the scoring , and chest CT results of 43.07%(118/274) cases met the positive criteria of chest CT screening. The 2019-nCoV nucleic acid test positive rate of cases with epidemiological history was 30.53%(40/131), which was higher than that of cases without epidemiological history (9.09%(13/143)), and that of cases with typical imaging performance on chest CT was 40.68%(48/118), which was higher than cases without typical imaging performance (3.21%(5/156)). The differences between the above groups were both statistically significant ( χ2=20.150、60.468, respectively, both P<0.01). The positive rates of viral nucleic acid detection in cases with positive findings of chest CT screening, scoring, series screening, and parallel screening were 40.68%(48/118), 23.74%(47/198), 44.68%(42/94) and 23.87%(53/222), respectively, while those in cases with negative findings of the four screening schemes were 3.20%(5/156), 7.89%(6/76), 6.11%(11/180) and 0(0/52), respectively. The positive rates of the four screening schemes were all significantly different from that of viral nucleic acid detection ( κ=0.402, 0.100, 0.431, 0.106, all P<0.01). The chest CT screening method had a sensitivity of 90.57%and a specificity of 68.33%, and an area under the operating characteristic curve of the subject was 0.794, which had higher diagnostic value than those of the other three screening schemes. Conclusions:For the screening and diagnosis of COVID-19 cases, epidemiological history, positive 2019-nCoV nucleic acid test with ≥2 typical clinical manifestations have highly diagnostic value. On the basis of the preliminary screening of chest CT examination, flexible analysis of the diagnostic results could improve the diagnostic value of each detection method.

Objective:To investigate the safety and efficacy of sacral neuromodulation(SNM)therapy for the treatment of lower urinary tract dysfunction(LUTD)in elderly patients.Methods:Clinical data of 91 elderly patients with LUTD from multiple medical institutions who received SNM during the period from January 2012 to December 2016 were retrospectively analyzed.Patients were divided into four groups: the interstitial cystitis(IC)group(n=28), the neurogenic bladder(NB)group(n=36), the overactive bladder syndrome(OAB)group(n=13)and the idiopathic dysuria(ID)group(n=14). Different sets of evaluation parameters were used for different diseases.Patients’ baseline data and data in stage I(test phase)and stage Ⅱ(permanent SNM)were recorded, statistically analyzed and compared.Results:Ninety-one people underwent SNM treatment.Of them, 53 patients received permanent implants(stage Ⅱ), and the total conversion rate of stage I to stage Ⅱ was 58.2%(53/91). Patients receiving permanent implants(stage Ⅱ)had a preoperative period ranging from 3 months to 30 years, and were followed up for 2 to 58 months after treatment, with an average follow-up of 19.6 months.The improvement rates in stage I for urinary urgency, daily urination frequency, daily nocturnal urination frequency, maximum urine volume, daily average urine volume, daily urine leakage frequency, and quality of life score were 35.4%, 31.6%, 33.7%, 32.6%, 49.2%, 43.2% and 13.2%, respectively.The improvement rates in stage Ⅱ for urinary urgency, daily urination frequency, daily nocturnal urination frequency, maximum urine volume, daily average urine volume, daily urine leakage frequency, and quality of life score were 43.2%, 40.0%, 37.8%, 50.5%, 70.5%, 70.4% and 43.2%, respectively.Three adverse events occurred, including 1 case of recurrent symptoms, 1 case of moderate infection, and 1 case of electrical lead dislocation.Conclusions:Sacral nerve stimulation has definitive and consistent curative effects on LUTD in elderly people.The follow-up time should be extended to further study the safety of sacral nerve stimulation.

Objective:The clinical efficacy, safety and quality of life in female patients with stress urinary incontinence (SUI)treated by midurethral sling were studied by multicenter retrospective study.Methods:From January 2018 to December 2018, 531 female patients with severe stress urinary incontinence from seven domestic urinary center were included in this study, including 78 cases from General Hospital of Central Theater Command, 122 cases from Shanghai Jiao tong University School of Medicine Affiliated Ren Ji Hospital, 67 cases from Shanghai Jiaotong University Affiliated First People’s Hospital, 68 cases from People’s Hospital of Jiangsu Province, 71 cases from The First Affiliated Hospital of Xi’an Jiaotong University, 65 cases from Zhejiang Provincial People’s hospital, 60 cases from Xiamen University First Affiliated Hospital. Among the 531 patients, 214 cases received TVT sling with an average age of (58.14±10.16) years. 181 cases were in postmenopausal(84.6%). The number of births ≥2 times was 89 (41.6%) cases. The score of ICI-Q-SF was 16.00±1.73. There were 166 cases of moderate incontinence (77.6%) and 48 cases of severe incontinence (22.4%). There were 317 patients in the TOT/TVT-O group with an average age of (58.33±10.25) years. 247 cases were in postmenopausal(77.9%). The number of births ≥2 times was 120 (37.8%) cases. The score of ICI-Q-SF was 15.79±1.75. There were 256 cases of moderate incontinence (80.8%) and 61 cases of severe incontinence (19.2%). There was no statistically significant difference in general data parameters between the two groups ( P>0.05). 1, 6, 12 months after the operation, the two groups of patients incontinence questionnaire Summary(ICI-Q-SF), common complications and Patient Global Impression of Improvement(PGI-I), satisfaction evaluation follow-up. ICI-Q-SF score improved > by 50% (cure + significant improvement) and 1-hour pad test <10 g (qualitative index) were used as the evaluation index of surgical success. Result:Both of the two surgical methods have high successive rate. There was no significant difference between 94.9% (203/214) of the TVT group and 93.7% (297/317) of the TOT/ TVT-O group ( P>0.05). Postoperative improvement of urinary incontinence (cure rate) [88.3% (189/214)]in the TVT group was slightly higher than that in the TOT/ TVT-O group [77.0% (244/317)] ( P<0.05). There was no change in the recurrence rate of urinary incontinence in the follow-up 6 and 12 months after the operation. There was no statistically significant difference between 4.4% (9/203) in the TVT group and 5.4% (16/297) in the TOT/TVT-O group ( P>0.05). The subjective cure rate 12 months after the operation was 96.3% (206/214) in the TVT group and 95.9% (304/317) in the TOT/TVT-O group ( P>0.05). 10 patients occurred bladder perforation occurred in the TVT group, and no bladder perforation occurred in the TOT/TVT-O group ( P<0.001). The incidence of pain and discomfort in the TVT group was significantly lower at 1.9% than that in the TOT/TVT-O group at 6.9% ( P<0.01). There was no statistically significant difference between the two groups in the incidence of complications such as dysuria/urinary retention, frequent urination/urgency incontinence. Both of them exposed sling ( P>0.05). Conclusion:Both TVT and TOT/TVT-O sling can effectively treat female stress urinary incontinence, and both can improve the sexual satisfaction of patients after the surgery, with fewer complications and other advantages. The selection of specific surgical methods in clinical practice can be individualized according to the patient's physical conditions, clinical needs and the operation methods familiar to doctors.

Patients in acute myocardial infarction (AMI) with serious complications such as malignant ventricular arrhythmia and cardiogenic shock couldn't receive emergency percutaneous coronary intervention (PCI) procedures and had high perioperative mortality. A case of AMI patients who suffered cardiac arrest and long-term cardiopulmonary resuscitation (CPR) was admitted to the department of critical care medicine of the First People's Hospital of Foshan. With the assistance of extracorporeal membrane oxygenation (ECMO), PCI and intra-aortic balloon counterpulsation (IABP) were performed. ECMO and ventilator were successfully weaned after anti-shock, mechanical ventilation, organ support treatment. The patient was successfully treated and discharged. After 6 months of follow-up, the patient recovered well in heart function.
