Objective:To explore the current status and training needs of nurses' knowledge, belief, and behavior regarding the good limb positioning in stroke patients with hemiplegia.Methods:From November to December 2023, convenience sampling was used to select 1 708 nurses from 30 ClassⅢ hospitals in 17 provinces across the country, who worked in departments such as Neurology and Rehabilitation. The self-designed General Information Questionnaire, Knowledge, Belief and Behavior Questionnaire for Putting Good Limb Position in Clinical Nurses, and self-designed Training Status and Needs Questionnaire for Good Limb Positioning were used for online surveys. Multiple linear regression was used to analyze the influencing factors of nurses' knowledge, belief, and behavior in good limb positioning.Results:A total of 1 622 valid questionnaires were collected. Nurses scored (135.64±25.93) on the Knowledge, Belief and Behavior Questionnaire for Putting Good Limb Position in Clinical Nurses, with the lowest score rate of 65.65% in the knowledge subscale and the highest score rate of 88.16% in the belief subscale. Multiple linear regression analysis showed that education level, working years, department, and whether they received training were the influencing factors of nurses' knowledge, belief, and behavior in good limb positioning ( P<0.05). 92.23% (1 496/1 622) of nurses were willing to receive training on good limb positioning, and 70.10% (1 137/1 622) of nurses participated in training on good limb positioning. Conclusions:Nurses generally have a moderate level of knowledge, belief, and behavior towards the good limb positioning, with room for improvement in their knowledge and behavior. However, their belief is relatively positive. Nursing managers should actively carry out training on good limb positioning based on the different characteristics and needs of nurses, improve their ability to good limb positioning.

Objective:To analyze the clinical characteristics of children with systemic lupus erythematosus (SLE) combined with thrombotic microangiopathy (TMA), and clarify the clinical outcomes and related risk factors of pediatric patients through their treatment and follow-up.Methods:This was a single-center retrospective case-control study. Children diagnosed with SLE combined with TMA between January 2017 and January 2023 at Beijing Children′s Hospital, Capital Medical University, were selected as the TMA group, and SLE children without TMA were selected as the control group.According to the prognosis, children in the TMA group were further divided into the good prognosis group and the poor prognosis group.The data of the children were collected, including age, gender, SLE disease activity, clinical presentations at the time of diagnosis and at the time of thrombosis, laboratory examinations, treatment strategies, prognosis, and follow-up results.The chi-square test and Z-test were used for comparison of count data.The t-test was used for comparison of metrological pairing data.The Fisher′s exact test was used to compare the differences between the 2 groups in categorical variables.The univariate Logistic regression was used to analyze the risk factors of poor prognosis. Results:There were 29 cases in the TMA group, and the incidence of TMA accounted for 2.53% of SLE patients; 33 cases were in the control group.The age at diagnosis of TMA was 13 years and 5 months (ranging from 9 years, 1 month and 5 days to 17 years and 4 months).The common clinical manifestations in order of prevalence were renal involvement (28 cases, 96.55%), hematologic involvement (26 cases, 89.66%), serous effusion (17 cases, 58.62%), rash (13 cases, 44.82%), and neurologic involvement (12 cases, 41.38%).Pleurisy or pericarditis, renal involvement and neurological involvement occurred more often in the TMA group than in the control group (17 cases vs.3 cases, 28 cases vs.10 cases, 12 cases vs.3 cases), and the TMA group showed less facial rash and arthritis than the control group (13 cases vs.25 cases, 4 cases vs.17 cases), and the differences were statistically significant (all P<0.05).The Systemic Lupus Erythematosus Disease Activity Index score in the TMA group [(24.14±9.42) scores] was significantly higher than that in the control group [(10.18±9.42) scores], and the difference was statistically significant ( t=3.233, P<0.05).The hemoglobin level, platelet count, and complement C3 level of the children in the TMA group were significantly lower than those in the control group, whereas the double stranded DNA antibody, lactate dehydrogenase, D-dimer, urea, creatinine, ferritin level, and urine protein quantitation were significantly higher than those in the control group, and the differences were statistically significant (all P<0.05).In the TMA group, 5 cases had decreased ADAMTS13 activity, and 5 cases had significantly increased complement C5b9.A total of 15 cases (51.72%) in the TMA group underwent renal biopsy, and 13 of them had combined renal TMA.In the TMA group, 28 patients (96.6%) received hormone therapy, 17 patients received plasma exchange, and 12 patients were treated with immunosuppressants and biologics; 19 patients (65.5%) improved, and 10 patients (34.5%) gave up the treatment due to deterioration of the disease.The urea level and peripheral blood fragmented erythrocyte rate in the good prognosis group were significantly lower than those in the poor prognosis group [(13.18±4.39) mmol/L vs.(21.16±10.14) mmol/L, t=2.975, P=0.006; 8/17 (47.06%) vs.7/7 (100%), χ2=5.929, P=0.015].The univariate Logistic regression analysis showed that the fragmented erythrocyte, ADAMTS13 activity and urea were the independent risk factors for poor prognosis (all P<0.05). Conclusions:SLE patients with moderate-to-severe disease activity, especially children with hemolytic anemia, thrombocytopenia, and renal dysfunction as prominent manifestations, should be alert to the risk of TMA.Early diagnosis and treatment are crucial.

The core components of the Hippo signaling pathway encompass upstream regulatory molecules,core kinase cascade complexes,and downstream transcriptional regulation complexes.This pathway modulates cellular behaviors by influencing the effector molecules of its core components and plays a pivotal role in immune regulation.Effector molecules,such as Yes-associated protein(YAP),transcriptional coactivator with PDZ-binding motif(TAZ),transcriptional enhanced associate domain transcriptional factor(TEAD),monopolar spindle-one binder(MOB1),large tumor suppressor(LATS),can stimulate fibroblast-like synovial cell migration and invasion in rheumatoid arthritis,regulate osteoarthritis disease progression,promote pathological new bone formation in ankylosing spondylitis,sustain submandibular gland development while delaying Sjogren's syndrome progression,mediate alpha-smooth muscle actin in systemic sclerosis,and refine the regulation of target genes associated with pulmonary fibrosis.This article provides an overview of the regulatory mechanisms involving Hippo signaling pathway-related effector molecules in the pathogenesis and progression of rheumatic immune system diseases,to serve as a reference for exploring novel therapeutic targets of rheumatic immune system diseases.

OBJECTIVES: Shelter hospital was an alternative way to provide large-scale medical isolation and treatment for people with mild coronavirus disease 2019 (COVID-19). Due to various reasons, patients admitted to the large shelter hospital was reported high level of psychological distress, so did the healthcare workers. This study aims to introduce a comprehensive and multifaceted psychosocial crisis intervention model. METHODS: The psychosocial crisis intervention model was provided to 200 patients and 240 healthcare workers in Wuhan Wuchang shelter hospital. Patient volunteers and organized peer support, client-centered culturally sensitive supportive care, timely delivery of scientific information about COVID-19 and its complications, mental health knowledge acquisition of non-psychiatric healthcare workers, group activities, counseling and education, virtualization of psychological intervention, consultation and liaison were exhibited respectively in the model. Pre-service survey was done in 38 patients and 49 healthcare workers using the Generalized Anxiety Disorder 7-item (GAD-7) scale, the Patient Health Questionnaire 2-item (PHQ-2) scale, and the Primary Care PTSD screen for the Diagnostic and Statistical Manual of Mental Disorders, 5th edition (PC-PTSD-5). Forty-eight healthcare workers gave feedback after the intervention. RESULTS: The psychosocial crisis intervention model was successfully implemented by 10 mental health professionals and was well-accepted by both patients and healthcare workers in the shelter hospital. In pre-service survey, 15.8% of 38 patients were with anxiety, 55.3% were with stress, and 15.8% were with depression; 16.3% of 49 healthcare workers were with anxiety, 26.5% were with stress, and 22.4% were with depression. In post-service survey, 62.5% of 48 healthcare workers thought it was very practical, 37.5% thought more practical; 37.5% of them thought it was very helpful to relief anxiety and insomnia, and 27.1% thought much helpful; 37.5% of them thought it was very helpful to recognize patients with anxiety and insomnia, and 29.2% thought much helpful; 35.4% of them thought it was very helpful to deal with patients' anxiety and insomnia, and 37.5% thought much helpful. CONCLUSIONS Psychological crisis intervention is feasible, acceptable, and associated with positive outcomes. Future tastings of this model in larger population and different settings are warranted.

【Objective】 To explore the efficacy of transurethral columnar balloon dilation of prostate (TUCBDP) and transurethral bipolar plasmakinetic resection of prostate (TUPKP) for patients with small volume (≤30 mL) benign prostatic hyperplasia (BPH) and the effects on urinary control and sexual function. 【Methods】 Clinical data of BPH patients who underwent surgical treatment during Jun.2021 and Jan.2022 were reviewed. A total of 95 patients with prostate volume ≤30 mL and regular sexual life were selected as subjects, including 45 patients who received TUCBDP as the TUCBDP group and 50 patients who received TUPKP as the TUPKP group. The patients were followed up for 12 months, and the perioperative data and follow-up results were analyzed. 【Results】 The TUCBDP group had shorter operation time, less intraoperative blood loss, less postoperative hemoglobin loss and sodium concentration loss, shorter bladder irrigation time, lower pain score, shorter urinary tube indwelling time and shorter hospital stay than the TUPKP group (P<0.05). Twelve months after surgery, the International Prostate Symptom score (IPSS), quality of life score (QoL), residual urine volume (PVR) and maximum urine flow rate (Qmax) were significantly improved in both groups (P<0.05). The International Index of Erectile Function-5 (IIEF-5), Erection Hardness Grading Score (EHS), Sexual Function Score in Patients with Premature Ejaculation-5 (CIPE-5) score had no significant differences compared with those before surgery (P>0.05). The TUPKP group had worse ejaculation function score and ejaculation disturbance score after surgery (P<0.05), while the TUCBDP group had no significant change (P>0.05), and the two indexes were superior in the TUCBDP group than in the TUPKP group. The TUCBDP group had significantly lower complication rate than the TUPKP group (P<0.05). 【Conclusion】 TUCBDP is safe and effective in the treatment of small volume (≤30 mL) BPH, less trauma, less biochemical interference, less pain, fewer complications, and shorter course of disease. It has little effect on the ejaculation function and erectile function, and is more suitable for patients requiring retention of sexual function. It has a good application prospect in the treatment of small volume BPH.

  Objective  To study the demographic and clinical characteristics, correlation of genotype and phenotype and treatment of Blau syndrome to facilitate early diagnosis and timely treatment of Blau syndrome.  Methods  Seventy-two patients with Blau syndrome from 11 centers from May 2006 to April 2022 were retrospectively analyzed, and their general information, clinical data, laboratory examination and treatment medication were collected.  Results  The distribution of patients with Blau syndrome was uniform in geographical north and south of China, and there was no obvious gender bias. The mean age of onset was (14.30±12.81) months, and the age of diagnosis was (55.18±36.22) months. 35% of patients with Blau syndrome happened before 1 year old, and all patients developed before 5 years old. 87.50% (63/72) had granulomatous arthritis, 65.28% (47/72) had rash, 36.11% (26/72) had ocular involvement, 27.78% (20/72) had fever, and 15.28% (11/72) had pulmonary involvement. Arthritic manifestations of Blau syndrome were most at risk, followed by rash, ocular involvement, and fever.The first 25 months of the disease, the risk of developing a rash was the greatest. The risk of developing arthritis was the greatest between 25 months and 84 months. The main mutations were p.R334Q and p.R334W, and patients with p.R334Q mutation had relatively high incidence of fever (35.71%[5/14] vs. 14.29%[1/7], P=0.43) and ocular involvement (42.86%[6/14]vs. 28.57%[2/7], P=0.51). There was a relatively high incidence of rash (85.71%[6/7] vs. 64.29%[9/14], P=0.59) in patients with the p.R334W mutation. Forty-five patients(62.50%)were treated with a combina-tion of glucocorticoid and methotrexate. Twenty-two patients were treated with tumor necrosis factor antagonist in addition to glucocorticoid and methotrexate.  Conclusions  The risk of different clinical manifestations of Blau syndrome from high to low was arthritis, followed by rash, ocular involvement and fever. The main treatment was glucocorticoid combined with methotrexate, to which biological agents could be added.

The main departments included neonatal diagnosis and treatment center （1 090 strains，accounting for 39.69％） [neonatal intensive care unit （279 strains，accounting for 10.16％），neonatal surgery department （223 strains，accounting for 8.12％），neonatal internal medicine department （209 strains，accounting for 7.61％），infant pediatrics department（200 strains，accounting for 7.28％） and premature pediatrics department（179 strains， accounting for 6.52％）]，hematology oncology department （216 strains，accounting for 7.87％），cardio vascular medicine department（206 strains，accounting for 7.50％）. Gram-positive bacteria accounted for 72.80％，Gram-negative bacteria 24.21％， fugus 2.99％. Among Gram-positive bacteria，coagulase negative staphylococcus（1 414 strains）and Staphylococcus aureus（146 strains）were the most common. The resistance rate of the former to penicillin G，oxacillin and erythromycin was more than 80％， and that of the latter to penicillin G and erythromycin was more than 80％. Among Gram-negative bacteria，Klebsiella pneumoniae （183 strains） and Escherichia coli （172 strains） were the most common. The resistance rates of the former to ampicillin， piperacillin，ampicillin/sulbactam and cefazolin were more than 80％，and the latter to ampicillin and tetracycline were more than 80％. Among the fungus，Candida albicans（42 strains）and Candida parapsilosis（22 strains）were the most common，and the resistance rate to common antifungal drugs was less than 10％. CONCLUSIONS：The pathogens of bloodstream infection in the hospital are complex，mainly coagulase negative staphylococcus and K. pneumoniae，and the drug resistance is severe.

Objective:To analyze the epidemiological and clinical characteristics of children with brucellosis, and to provide a practical basis and experience for clinical diagnosis and treatment of brucellosis.Methods:Retrospective analysis was used to collect clinical data of children with brucellosis diagnosed at the Children's Hospital Affiliated to Zhengzhou University from May 2015 to October 2017, and their epidemiological characteristics, clinical manifestations, laboratory tests, and clinical diagnosis and treatment were summarized.Results:A total of 24 children were included, including 14 males and 10 females, with an average age of 6 years (1 year 2 months to 12 years old). Except February, onset throughout the year, higher incidence was from May to July (14 cases, 58.33%). The exposure history of the children was mainly exposure to cattle and sheep and consumption of beef and mutton (18 cases, 75.00%). The main clinical manifestations were fever in 24 cases (100.00%), bone and joint pain in 14 cases (58.33%), hepatomegaly in 9 cases (37.50%), splenomegaly in 7 cases (29.17%). Tube agglutination test (SAT) was positive in 21 cases (87.50%), weakly positive in 1 case (4.17%) and negative in 2 cases (8.33%). Brucella was detected in all 24 cases by microbial culture, and in 18 cases (75.00%) by blood culture. Eighteen cases (75.00%) had liver dysfunction. Thirteen cases were misdiagnosed, and the misdiagnosis rate was as high as 54.17%. Twenty-two cases had been cured after treatment, 2 cases relapsed and recovered after continued treatment. Conclusions:Children with brucellosis have diverse epidemiology and clinical features, and are easily misdiagnosed. For children with fever, bone and joint pain and exposure history, pediatricians should be alert to the possibility of brucellosis, conduct microbiological and serological tests, in order to timely, accurate and standardized diagnosis and treatment of children with brucellosis.

Objective:To evaluate the biosafety of medical injectable carboxymethyl glycosaminoglycan gel.Methods:Ames test, chromosome aberration test in vitro and gene mutation test in vitro were used to detect the genotoxicity of the medical carboxymethyl glycosaminoglycan gel. The gel saline extract (50 ml/kg) was injected slowly through the marginal vein of the ear into Japanese big-eared rabbits. The body temperature was measured and the temperature rise was calculated. The gel saline extract (50 ml/kg) and normal saline (control) were injected intraperitoneally and intravenously into the Kunming mice, respectively. The toxicity response in mice was observed after injection, and bodyweight change was valued. The gel saline extract, normal saline and distilled water were added into the rabbit anti-clotting, to detect the rate of hemolysis.Results:Under active and inactive conditions, the number of spontaneous revertants of the 4 strains of gel saline extract group and gel DMSO extract group did not reach 2 times of that of the corresponding negative control group. The rate of chromosome aberration of the three dose groups were 0. There was no significant increase in the large colony mutation frequency, small colony mutation frequency and total mutation frequency in three dose groups (all P>0.05). After injection of gel saline extract for 24, 48 and 72 h, no toxic reaction was found in each group of mice. With the extension of time after injection, the body weight of mice in the sample group and the control group increased, but the difference was not statistically significant ( P>0.05). After injection of gel saline extract, the temperature rise of 3 Japanese big-eared rabbits were 0.0, 0.3 and 0.2 ℃ respectively. The results of hemolysis test showed that the hemolysis rate of the polycarboxymethyl glucosamine gel was 0.1%. Conclusions:No genetic toxicity changes were found in carboxymethyl glycosaminoglycan to induce gene mutation or chromosome damage in bacteria and cells, and no pyrogenicity, acute systemic toxicity and hemolysis were observed. These results indicate that thecarboxymethyl glycosaminoglycan gel has good biosafety.

We analyzed the influenza surveillance data of Children′s Hospital of Suzhou University from 2016 to 2018 and estimated the hospitalization burden of children under 5 years old due to influenza infection in Suzhou. The results showed that the influenza virus positive rate of 1 451 severe acute respiratory infection (SARI) cases in Children′s Hospital of Suzhou University was 13.6% (95%CI: 11.8%-15.3%; 197 cases), among which the influenza pandemic intensity in 2017-2018 was relatively high, and A/H1N1 was the main pandemic virus. It was estimated that the hospitalization rate of influenza-related SARI in children under 5 years old in Suzhou was 6.9‰ (95%CI: 6.6‰-7.2‰), among which the hospitalization rate of children aged<6 months was higher, up to 11.4‰ (95%CI: 9.9‰-12.8‰).
