Background With the continuous development of the healthcare industry, healthcare workers face increasing pressure, including long-term shift work and workplace violence from patients or their relatives. This not only affects the physical and mental health of healthcare workers but may also negatively impact the quality of patient care and the efficiency of medical services. Objectives To analyze the pathways through which shift work and workplace violence affect healthcare workers' self-rated health and depression symptoms, explore potential mediating role of job burnout, and conduct subgroup analyses to reveal differences among various groups. Methods Data were collected from 3706 frontline healthcare workers across 23 provinces from January 10 to February 5, 2019, using a snowball sampling method. The survey included basic demographic information, self-rated health, depression symptoms [assessed using the Patient Health Questionnaire-2 (PHQ-2)], workplace violence experience assessed using the Workplace Violence Scale), and job burnout (assessed using the Chinese Maslach Burnout Inventory). Data were analyzed using logistic regression, structural equation modeling (for mediating effects), and subgroup analysis to examine the impacts of shift work and workplace violence on health and depression symptoms. Results Among the subjects, 2700 workers (73.29%) reported shift work experience, 2079 workers (56.43%) experienced workplace violence, 633 workers (17.18%) reported poor self-rated health, and 687 workers (18.65%) reported depression symptoms. Shift work was associated with self-rated health (OR=0.572, 95%CI: 0.461, 0.710) and depression symptoms (OR=1.519, 95%CI: 1.190, 1.938), while workplace violence also associated with self-rated health (OR=0.566, 95%CI: 0.471, 0.681) and depression symptoms (OR=2.096, 95%CI: 1.740, 2.525). Job burnout significantly mediated the effects of shift work and workplace violence on self-rated health (indirect effects: −0.023, −0.027) and depression symptoms (indirect effects: 0.032, 0.037) (all P < 0.001). The subgroup analysis revealed that age, marital status, physical exercise, smoking, and alcohol consumption influenced the impacts of shift work and workplace violence on health. Conclusion Shift work and workplace violence significantly affect healthcare workers' self-rated health and depression symptoms, with job burnout playing a key mediating role in this process. This suggests that healthcare institutions should improve resource allocation, provide flexible scheduling systems, ensure adequate rest time, and increase psychological support and safety measures to help healthcare workers better cope with work-related stress and violence.

OBJECTIVE: To observe the effects of electroacupuncture (EA) on improving motor function and regulating microglial activation based on Notch receptor 1 (Notch1)/Hes family bHLH transcription factor 1 (Hes1) pathway in mice with Parkinson's disease (PD). METHODS: Thirty-six male C57BL/6 mice were randomly divided into a control group, a model group and an EA group, 12 mice in each group. PD model was established by intraperitoneal injection of 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) for 7 consecutive days in the model group and the EA group. From the 1st day of modeling, EA was applied at "Baihui" (GV20) and bilateral "Shenshu" (BL23) in the EA group, with continuous wave, in frequency of 2 Hz and current of 2 mA, 15 min a time, once a day for 14 days continuously. The behavioral performance was evaluated by gait test, pole climbing test and hanging test, the number of positive cells of tyrosine hydroxylase (TH) and the co-expression positive cells of Notch1/ionized calcium binding adaptor molecule 1 (Iba-1) in the substantia nigra of midbrain was assessed by immunofluorescence, the protein expression of TH, α-synuclein (α-syn), Notch1, Hes1, Iba-1, inducible nitric oxide synthase (iNOS), Arginase-1 (ARG1), tumor necrosis factor-α (TNF-α), interleukin (IL)-1β, IL-6 and IL-10 was detected by Western blot, the mRNA expression of Notch1 and Hes1 was detected by real-time PCR. RESULTS: Compared with the control group, in the model group, the stride frequency was accelerated (P<0.001) and the stride length was shortened (P<0.001) for the four limbs, the pole climbing test time was prolonged (P<0.01) and the grip level was reduced (P<0.01); in the substantia nigra of midbrain, the number of positive cells of TH was decreased (P<0.001), the number of co-expression positive cells of Notch1/Iba-1 was increased (P<0.001), the protein expression of α-syn, Notch1, Hes1, Iba-1, iNOS, TNF-α, IL-1βand IL-6 was increased (P<0.01, P<0.05, P<0.001), the protein expression of TH, ARG1 and IL-10 was decreased (P<0.01, P<0.001), the mRNA expression of Notch1 and Hes1 was increased (P<0.01). Compared with the model group, in the EA group, the stride frequency was decelerated (P<0.001) and the stride length was increased (P<0.05, P<0.01, P<0.001) for the four limbs, the pole climbing test time was shortened (P<0.05) and the grip level was increased (P<0.05); in the substantia nigra of midbrain, the number of positive cells of TH was increased (P<0.01), the number of co-expression positive cells of Notch1/Iba-1 was decreased (P<0.001), the protein expression of α-syn, Notch1, Hes1, Iba-1, iNOS, TNF-α, IL-6 and IL-1β was decreased (P<0.05, P<0.01), the protein expression of TH, ARG1 and IL-10 was increased (P<0.05, P<0.001, P<0.01), the mRNA expression of Notch1 and Hes1 was decreased (P<0.05). CONCLUSION EA can improve the behavioral performance and protect the dopaminergic neurons in PD mice, its mechanism may relate to the inhibition of Notch1/Hes1-mediated neuroinflammation, thus inhibiting the microglial activation.

Objective To evaluate the clinical value of loop-mediated isothermal amplification(LAMP)for rapid detection of neonatal infectious pathogens.Methods Biological samples(cord blood and neonatal blood or sputum within 48 hours of birth)of 167 suspected neonates and premature infants delivered in Jinhua Maternal and Child Health Hospital from June 2021 to December 2022 were collected and tested by LAMP method and bacterial culture method respectively.The results of the two methods were compared consistent-ly.Using the bacterial culture method as the standard,the positive rate of LAMP method was evaluated in de-tecting common pathogens in neonatal infections.Results Among the 167 specimens,the positive rate of pathogen detection by LAMP method(24.0％)was higher than that by bacterial culture method(15.0％),and the difference was statistically significant(x2=4.30,P＜0.05).The positive rate of LAMP method for detecting methicillin-resistant Staphylococcus aureus was higher than that of bacterial culture method,and the difference was statistically significant(x2=15.59,P＜0.01).Conclusion Compared with bacterial culture method,LAMP method has a higher positive rate for detecting methicillin-resistant Staphylococcus aureus,and can quickly and accurately diagnose the pathogenic bacteria of neonatal infections,providing a basis for the rapid development of clinical diagnosis and treatment strategies.

Objective To systematic evaluate the impact of applying the clinical nursing pathway(CNP)on epidural anesthetic analgesia natural delivery.Methods The randomized controlled trial(RCT)and quasi-experimental researches on the application of CNP in epidural anesthetic analgesia natural delivery were retrieved from PubMed,Cochrane Library,Embase,Web of Science,China Knowledge Network database,Wanfang database,VIP and the Chinese Biomedical Literature Database.The retrieval time limit was from January 1,2014,to July 31,2024 with no language limitation.The meta analysis on the included studies was performed by applying RevMan5.4.1.Results A total of 5 RCTs and 2 quasi-experimental studies were in-cluded,involving 979 parturients with deliveries.The meta analysis showed that compared with the conven-tional nursing,CNP could shorten the duration of the first stage of labor(MD=—1.06,95％CI:—1.95——0.17,P=0.02)and the duration of the second stage of labor(MD=—0.12,95％CI:—0.21——0.03,P=0.006);decreased the rate of perineal lateral incision(RR=0.73,95％CI:0.65-0.83,P＜0.001)and inci-dence rate of postpartum urinary retention(RR=0.35,95％CI:0.20-0.63,P＜0.001);and shortened the time to lactation initiation(SMD=—1.52,95％CI:—2.38——0.66,P＜0.001).There was no influence on reducing postpartum 24 h hemorrhage amount(SMD=—0.51,95％CI:—1.23-0.21,P=0.16).The study subjects were divided into the primipara women subgroup and unclassified parturients subgroup.Compared with the conventional nursing group,compared with the conventional nursing,CNP had no impact on the dura-tion of the first stage of labor(MD=—0.32,95％CI:—0.61-0.98,P=0.63)and the duration of the second stage of labor(MD=—0.11,95％CI:—0.25-0.04,P=0.15)in the primipara women subgroup.CNP could reduce the postpartum 24 h hemorrhage volume in the unclassified parturients subgroup(SMD=—1.47,95％CI:—1.72——1.21,P＜0.001).Conclusion Application of CNP in parturients labor analgesia could reduce the perineal lateral incision rate and incidence rate of postpartum urinary retention and shorten the time to lac-tation initiation.Due to the heterogeneity among studies,the impact of CNP on the labor duration and the bleeding amount within postpartum 24 h still requires more high-quality studies to be conducted in the future for verification.

Objective:To investigate the clinical features and prognosis of male with anti-melanoma differentiation-associated gene 5 (MDA5) autoantibody.Methods:The clinical data of 246 patients with DM and anti-MDA5 autoantibodies hospitalized by Jiangsu Myositis Cooperation Group from 2017 to 2020 were collected and retrospectively analyzed. Chi-square test was performed to compared between counting data groups; Quantitative data were expressed by M ( Q1, Q3), and rank sum test was used for comparison between groups; Single factor survival analysis was performed by Kaplan-Meier method and Log rank test; Cox regression analysis were used for multivariate survival analysis. Results:①The male group had a higher proportion of rash at the sun exposure area [67.1%(47/70) vs 52.8%(93/176), χ2=4.18, P=0.041] and V-sign [50.0%(35/70) vs 30.7%(54/176), χ2=8.09, P=0.004] than the female group. The male group had higher levels of creatine kinase [112(18, 981)U/L vs 57 (13.6, 1 433)U/L, Z=-3.50, P<0.001] and ferritin [1 500 (166, 32 716)ng/ml vs 569 (18, 14 839)ng/ml, Z=-5.85, P<0.001] than the female group. The proportion of ILD [40.0%(28/70) vs 59.7%(105/176), χ2=7.82, P=0.020] patients and the red blood cell sedimentation rate[31.0(4.0, 101.5)mm/1 h vs 43.4(5.0, 126.5)mm/1 h, Z=-2.22, P=0.026] in the male group was lower than that of the female group, but the proportion of rapidly progressive interstitial lung disease (PR-ILD) [47.1%(33/70) vs 31.3%(55/176), χ2=5.51, P=0.019] was higher than that of the female group. ②In male patients with positive anti-MDA5 antibodies,the death group had a shorter course of disease[1.0(1.0, 3.0) month vs 2.5(0.5,84) month, Z=-3.07, P=0.002], the incidence of arthritis [16.7%(4/24) vs 42.2%(19/45), χ2=4.60, P=0.032] were low than those in survival group,while aspartate aminotransferase (AST)[64(22.1, 565)U/L vs 51(14,601)U/L, Z=-2.42, P=0.016], lactate dehydrogenase (LDH) [485(24,1 464)U/L vs 352(170, 1 213)U/L, Z=-3.38, P=0.001], C-reactive protein (CRP) [11.6(2.9, 61.7) mg/L vs 4.95(0.6, 86.4) mg/L, Z=-1.96, P=0.050], and ferritin levels [2 000(681, 7 676) vs 1 125 (166, 32 716)ng/ml, Z=-3.18, P=0.001] were higher than those in the survival group, and RP-ILD [95.8%(23/24) vs 22.2%(10/45), χ2=33.99, P<0.001] occurred at a significantly higher rate. ③Cox regression analysis indicated that the course of disease LDH level, and RP-ILD were related factors for the prognosis of male anti-MDA5 antibodies [ HR (95% CI)=0.203(0.077, 0.534), P=0.001; HR (95% CI)=1.002(1.001, 1.004), P=0.003; HR (95% CI)=95.674 (10.872, 841.904), P<0.001]. Conclusion:The clinical manifestations of male anti-MDA5 antibody-positive patients are different from those of female. The incidence of ILD is low, but the proportion of PR-ILD is high. The course of disease, serum LDH level, and RP-ILD are prognostic factors of male anti-MDA5 antibody-positive patients.

Objective:To explore the genetic etiology and clinical outcome of a child with co-morbid progressive IgA nephropathy and COQ8B-associated glomerulopathy. Methods:A child who was admitted to Peking University First Hospital on March 2, 2021 was selected as the study subject. Genomic DNA was extracted from peripheral blood samples from the child and his parents and sister. Whole exome sequencing was carried out, and candidate variant was verified by Sanger sequencing. This study was approved by Medical Ethics Committee of the Peking University First Hospital (Ethics No. 2016[1029]).Results:The child, a 7-year-old boy who had developed proteinuria 8 months before, was diagnosed with IgA nephropathy (M1E1S1T1C1). With steroid, cyclophosphamide, cyclosporine and angiotensin-converting enzyme inhibitor therapy, partial remission of proteinuria was achieved. However, his serum creatinine level had increased from 53.8 mol/L at the onset of disease to 86.7 mol/L after 3.9 years, along with massive proteinuria. Kidney biopsy still indicated IgA nephropathy (M0E0S1T0C0). The child was found to harbor a homozygous c. 737G>A (p.Ser246Asn) missense variant of the COQ8B gene, for which his parents and sister were heterozygous carriers. The variant was predicted to be pathogenic (PS1+ PM2_Supporting+ PM3+ PP3+ PP4) based on the guidelines from the American College of Medical Genetics and Genomics. The child was treated with high-dose coenzyme Q10 in combination with steroid and/or mycophenolate mofetil, though his serum creatinine level still increased to 286 mol/L after 7.3 years, which conformed to a chronic kidney disorder with glomerular filtration rate category of G3b. Conclusion:The homozygous c.737G>A missense variants of the COQ8B gene probably underlay the progressive kidney dysfunction in this child. For children with IgA nephropathy presenting with atypical clinical manifestations, unsatisfactory therapeutic effect, and/or early onset of kidney function decline, coexistence of other diseases should be suspected.

Objective:The study aimed to analyze the risk variables influencing the prognosis of patients with sepsis-associated delirium (SAD) in the Intensive Care Unit (ICU) and build a prediction nomogram.Methods:This was a retrospective cohort study that includes patients with SAD in the Medical Information Mart for Intensive CareⅢ database (MIMIC-Ⅲ) database as training cohort, and patients who were hospitalized in the First Hospital of Jiaxing from January 2021 to September 2022 as validation cohort. Inclusion criteria: (1) age≥18 years old; (2) being admitted to the ICU for the first time; (3) the length of ICU stay≥24 h; (4) consistent with the diagnosis of sepsis; (5) the diagnosis of delirium was identified by CAM-ICU questionnaire. The general information, vital signs, past medical history and laboratory examination results of the patients were collected, and the outcome was 28-day mortality. Multiple logistic regression was used to identify independent influencing factors and the nomogram was constructed. The validity of the prediction model was determined using multiple indicators, including calibration curve, the area under the receiver operating characteristic curve (AUC), decision curve analysis (DCA), and Hosmer-Lemeshow test.Results:A total of 250 patients were included in the training cohort and 154 patients were in the validation cohort. The multiple logistic regression demonstrated that age ( OR=1.057, 95% CI: 1.030-1.084, P<0.001), respiratory frequency ( OR=1.117, 95% CI: 1.037-1.202, P=0.003), lactic acid ( OR=1.137, 95% CI:1.011-1.279, P=0,032), hemoglobin ( OR=0.983, 95% CI: 0.970-0.997, P=0.020), SOFA score ( OR=1.184, 95% CI: 1.070-1.309, P=0.001) were independent risk factors associated with the 28-day mortality of patients with SAD. The AUC of the nomogram created by the five factors above was 0.773 (95% CI: 0.705-0.841), and the Hosmer-Lemeshow test showed that the model was a good fit ( P=0.875). The DCA curve indicates that the model has potential net benefit. The AUC was 0.864 (95% CI: 0.799-0.928) in the validation cohort, and the Hosmer-Lemeshow test showed that the model was a good fit ( P=0.488). The DCA curve indicates that the model of the validation cohort had potential net benefit. Conclusion:The prediction model based on age, respiratory frequency, lactate, hemoglobin, and SOFA scores shows valuable capability of predicting the prognosis of patients with SAD, which could help clinicians identify risk factors at first time and make earlier intervention.

Objective To explore the clinical efficacy of oxygen blowing combined with clostridium butyricum and bifidobacterium powders in neonatal diaper dermatitis(DD).Methods Data of neonatal DD patients admitted to the Department of Pediatrics of the Affiliated Hospital of Hangzhou Normal University from January 2019 to June 2021 were retrospectively analyzed.They were divided into the control group(oxygen blowing)and the experimental group(oxygen blowing combined with clostridium butyricum and bifidobacterium powders)according to whether or not they received clostridium butyricum and bifidobacterium powders treatment.The primary efficacy index of the study was the treatment efficiency,and the secondary efficacy indexes were the severity of DD(Neonatal Rash Scale score,DD score,and lesion area score),time to erythema resolution,time to vesicle resolution,and time to healing.Results A total of 99 patients were included in the study,with 42 in the experimental group and 57 in the control group.The treatment efficiency of the experimental group was significantly higher than that of the control group(P＜0.05).With regard to the severity of DD,the papule and pustule scores,dermatitis extent scores,erythema severity scores,skin damage scores and lesion area scores of the experimental group were significantly lower than those of the control group(P＜0.05);the proportions of moderate and severe syndrome in the experimental group were lower than those of the control group(P＜0.05).The time for erythema to subside,the time for vesicles to subside and the time for healing were shorter in the experimental group than in the control group(P＜0.05).Conclusion Oxygen blowing combined with clostridium butyricum and bifidobacterium powders can significantly improve the clinical effect of neonatal DD,but the specific mechanism still needs to be explored.

Abstract The popularity of electronic devices helps the spread of the flow experience. Flow experience affects many aspects of life for adolescents as for its double articulation. In order to provide suggestions for the improvement in adolescent mental health, this paper reviews flow experience and adolescent mental health in different situations. In learning situation, the state of flow makes a difference in students self confidence, learning experience, positive affect in school, positivity, self esteem and self efficacy, etc., at the same time, it is beneficial to relieve academic pressure and academic procrastination. In entertainment situation, the state of flow experience directly leads to addiction, and indirectly affects online game addiction by the mediating roles of self control and cognitive bias.

H 1-antihistamines are widely used in the treatment of various allergic diseases, but there are still many challenges in the safe and rational use of H 1-antihistamines in pediatrics, and there is a lack of guidance on the prescription review of H 1-antihistamines for children.In this paper, suggestions are put forward from the indications, dosage, route of administration, pathophysiological characteristics of children with individual difference and drug interactions, so as to provide reference for clinicians and pharmacists.
