Objective: To investigate the epidemiological characteristics of human brucellosis in Jiande City, Zhejiang Province from 2005 to 2024, so as to provide the evidence for strengthening the prevention and control of brucellosis. Methods: Data on brucellosis cases and surveillance in Jiande City from 2005 to 2024 were collected through the Chinese Disease Prevention and Control Information System, the annual brucellosis surveillance reports from the Jiande Center for Disease Control and Prevention, and the annual summaries of brucellosis prevention and control efforts. The epidemiological characteristics of human brucellosis were analyzed using a descriptive epidemiological method. Results: A total of 1 125 individuals were monitored in Jiande City from 2005 to 2024, with 18 seropositive cases identified and the seropositivity rate of 1.60%. The average annual seropositivity rate from 2015 to 2024 was 3.35%, which was significantly higher than that of 0.57% from 2005 to 2014 (P<0.05). There were 10 confirmed brucellosis cases and 8 asymptomatic infections, with no reported deaths. The peak incidence occurred between March and August. Among the 16 towns (streets) in Jiande City, 8 reported brucellosis cases. Of the brucellosis cases, 14 were male and 4 were female, with a male-to-female ratio of 3.5∶1. The majority of cases (13 cases) were aged between 40 and 60 years. Occupational exposure was identified in 16 cases, all of whom were infected through direct hand contact with the excreta, secretions, or animal products of infected sheep or cattle. The primary source of infection was sheep, followed by cattle. Five strains of Brucella were isolated and cultured, all identified as Brucella melitensis biovar 3. Conclusions The brucellosis epidemic in Jiande City remained at a sporadic and low prevalence level from 2005 to 2024, with an increasing trend observed from 2015 to 2024. Male occupational groups aged 40 to 60 years were the key population for brucellosis prevention and control, and sheep were the primary source of infection.

Objective To explore the effect of ritodrine hydrochloride combined with magnesium sulfate in the treatment of threatened abortion in older patients with a second child and to analyze its possible mechanism of action.Methods From March 2020 to December 2021,100 older second-child patients with threatened abortion at Handan Maternal and Child Health Hospital were selected and divided into control and observation groups using a random number table method,with 50 cases in each group.The control group was treated with magnesium sulfate based on general intervention measures(bed rest,intermittent oxygen inhalation,nutrition intake,and psychological nursing),while the observation group was treated with ritodrine hydrochloride combined with magnesium sulfate based on general inter-vention measures.The treatment effects,immunoregulatory function indicators[serum blocking antibody(BA)and anticardiolipin antibody(ACA)],sex hormone levels[progesterone(P),estradiol(E2),β-human chorionic gonadotropin(β-hCG)]and related cytokines[pregnan-cy-associated plasma protein A(PAPP-A),human leukocyte antigen G(HLA-G),and interleukin-10(IL-10)]before and after treatment,as well as maternal and infant outcomes and adverse reactions were compared.Results The total efficacy rate was higher in the observa-tion group than in the control group(96％vs.80％,P＜0.05).Compared with before treatment,the serum BA-positivity rate significantly increased and the ACA-positivity rate significantly decreased in both groups after treatment(both P＜0.05).However,after treatment the serum BA-positivity rate was higher in the observation group than in the control group,and the ACA-positivity rate was lower than that in the control group(both P＜0.05).Compared with before treatment,the serum P,E2,β-hCG,PAPP-A,HLA-G,and IL-10 levels signifi-cantly increased at the end of treatment and 2 weeks after treatment in both groups.The levels of sex hormones and related cytokines in the observation group were higher than those in the control group at the end of treatment and two weeks after treatment(both P＜0.05).The success rates of pregnancy maintenance,full-term delivery,and natural labor were higher in the observation group than in the control group;however,the incidences of abortion,premature delivery,cesarean section,and adverse neonatal outcomes were lower than those in the control group(all P＜0.05).There was no significant difference in the incidence of adverse reactions between the two groups(P＜0.05).Conclusion The combination of ritodrine hydrochloride and magnesium sulfate has significant therapeutic effects in the treatment of threatened abortion in older women with a second pregnancy.It can improve maternal immune regulation,regulate sex hormone levels and PAPP-A,HLA-G,and IL-10 levels,reduce adverse maternal and fetal outcomes,and does not increase adverse reactions.

Objective:To explore the current status and correlation of occupational stress and burnout among pediatric nurses.Methods:From April 2023 to January 2024, convenience sampling was used to select 150 pediatric nurses from Taizhou Hospital of Zhejiang Province, East Campus of Taizhou Hospital of Zhejiang Province, and Taizhou Enze Medical Center as research subjects. The survey was conducted using the General Information Questionnaire, Chinese version of the Maslach Burnout Inventory General Survey, and Nurse Job Stressors Scale.Results:A total of 150 nurses were surveyed, and 149 valid questionnaires were collected, with a valid response rate of 99.33%. Pediatric nurses had high scores in emotional exhaustion and depersonalization dimensions in occupational burnout. The job stressors for pediatric nurses were ranked in order of their scores in each dimension, including workload and time management, work environment and resources, nursing profession and work, management and interpersonal relationships, and patient nursing. There were correlations between occupational burnout and occupational stress among pediatric nurses in multiple dimensions (all P<0.05) . Conclusions:Pediatric nurses have a relatively high level of occupational burnout and often face significant occupational stress. In the development of the healthcare system, attention should be paid to the occupational burnout and stress of pediatric nurses. The physical and mental health of pediatric nursing staff can be promoted and work efficiency can be improved by reducing the overloaded work of pediatric nurses, optimizing personnel allocation, and improving social support.

The condition of patients with severe traumatic brain injury (sTBI) complicated by corona virus 2019 disease (COVID-19) is complex. sTBI can significantly increase the probability of COVID-19 developing into severe or critical stage, while COVID-19 can also increase the surgical risk of sTBI and the severity of postoperative lung lesions. There are many contradictions in the treatment process, which brings difficulties to the clinical treatment of such patients. Up to now, there are few clinical studies and therapeutic norms relevant to sTBI complicated by COVID-19. In order to standardize the clinical treatment of such patients, Critical Care Medicine Branch of China International Exchange and Promotive Association for Medical and Healthcare and Editorial Board of Chinese Journal of Trauma organized relevant experts to formulate the Chinese expert consensus on clinical treatment of adult patients with severe traumatic brain injury complicated by corona virus infection 2019 ( version 2023) based on the joint prevention and control mechanism scheme of the State Council and domestic and foreign literatures on sTBI and COVID-19 in the past 3 years of the international epidemic. Fifteen recommendations focused on emergency treatment, emergency surgery and comprehensive management were put forward to provide a guidance for the diagnosis and treatment of sTBI complicated by COVID-19.

Traumatic cerebrospinal fluid leakage commonly presents in traumatic brain injury patients, and it may lead to complications such as meningitis, ventriculitis, brain abscess, subdural hematoma or tension pneumocephalus. When misdiagnosed or inappropriately treated, traumatic cerebrospinal fluid leakage may result in severe complications and may be life-threatening. Some traumatic cerebrospinal fluid leakage has concealed manifestations and is prone to misdiagnosis. Due to different sites and mechanisms of trauma and degree of cerebrospinal fluid leak, treatments for traumatic cerebrospinal fluid leakage varies greatly. Hence, the Craniocerebral Trauma Professional Group of Neurosurgery Branch of Chinese Medical Association and the Neurological Injury Professional Group of Trauma Branch of Chinese Medical Association organized relevant experts to formulate the " Chinese expert consensus on the diagnosis and treatment of traumatic cerebrospinal fluid leakage in adults ( version 2023)" based on existing clinical evidence and experience. The consensus consisted of 16 recommendations, covering the leakage diagnosis, localization, treatments, and intracranial infection prevention, so as to standardize the diagnosis and treatment of traumatic cerebrospinal fluid leakage and improve the overall prognosis of the patients.

Depression is a common mental illness in the elderly, which is associated with compromised quality of life, disability, suicide risk and mortality.Drug treatment of late-life depression has large adverse reactions and is prone to drug resistance.Therefore, non-pharmacological interventions have gradually become a research hotspot.This paper reviewed the research progress of non-pharmacological interventions of late-life depression at home and abroad in recent years, and provides a theoretical basis for further research on effective treatment of late-life depression.

Objective To evaluate the risk factors for development of primary hepatic carcinoma(PHC)in patients with hepatitis B virus-related liver cirrhosis.Methods The cases of hepatitis B virus-related liver cirrhosis combined with PHC and hepatitis B virus-related liver cirrhosis alone were retrospectively analyzed in the Second Affiliated Hospital of Nanchang University.A total of 151 patients with hepatitis B virus-related liver cirrhosis combined with PHC were included in observation group and 136 patients with hepatitis B virus-related liver cirrhosis alone were included in control group.We have down the analysis of risk factors by χ2 test,t test and Logistic regression model.Results The clinical data of the two groups of patients showed statistically significant differences in six indicators,including gender,hepatitis B virus e antibodies(Anti-HBe),liver function grading(Child-Pugh),alpha-fetoprotein(AFP),blood glucose,and blood type,through univariate analysis(P<0.05).The results of multivariate unconditional Logistic regression analysis showed that AFP(OR=5.046,2.716,and 9.373,P<0.01)and Anti-HBe positive(OR=2.305,1.075,and 4.945,P<0.01)were risk factors for primary liver cancer.Conclusion Male shows a more possibility of occurrence of PHC than female.The positive Anti-HBe is the independent risk factors for PHC.The probability of PHC in Child-Pugh stage A is higher than that in Child-Pugh stage B and C.

Objective:To investigate the knowledge, attitudes, and practices (KAP) of pulse oximetry among pediatric healthcare providers in China and analyze the factor influencing the KAP.Methods:A self-developed questionnaire was used for an online research on the KAP of 11 849 pediatric healthcare providers from 31 provinces, autonomous regions, and municipalities of China from March 11 to 14, 2022.The factors influencing the KAP of pulse oximetry among pediatric healthcare providers were examined by Logistic regression. Results:The scores of KAP, of pulse oximetry were 5.57±0.96, 11.24±1.25 and 11.19±4.54, respectively.The corresponding scoring rates were 69.61%, 74.95%, and 55.99%, respectively. Logistic regression results showed that the gender and working years of pediatric healthcare providers, the region they were located, and whether their medical institution was equipped with pulse oximeters were the main factors affecting the knowledge score (all P<0.05). Main factors influencing the attitude score of pediatric healthcare providers included their knowledge score, gender, educational background, working years, region, medical institution level, and whether the medical institution was equipped with pulse oximeters (all P<0.05). For the practice score, the main influencing factors were the knowledge score, gender, age, and whether the medi-cal institution was equipped with pulse oximeters (all P<0.05). Conclusions:Chinese pediatric healthcare providers need to further improve their knowledge about and attitudes towards pulse oximetry.Pulse oximeters are evidently under-used.It is urgent to formulate policies or guidelines, strengthen education and training, improve knowledge and attitudes, equip more institutions with pulse oximeters, and popularize their application in medical institutions.

Objective:To explore the effect of pelvic floor muscle functional exercise based on Snyder hope theory in patients after prophylactic stoma retraction.Methods:74 patients with low rectal cancer who underwent prophylactic stoma retraction from July 2019 to June 2021 were randomly divided into intervention group and control group. The patients in the control group received routine nursing and pelvic floor muscle functional exercise. The patients in the intervention group received functional exercise intervention based on Snyder′s hope theory on the basis of the control group. The hope level and self-care ability of the patients in the two groups were evaluated before the intervention and 3 months after stoma restitution. The anal function of the patients in the two groups was evaluated 1 month and 3 months after stoma restitution.Results:Before the intervention, there was no significant difference in the score of hope level and self-care ability between the two groups ( P>0.05). Three months after the operation, the score of hope level in the observation group was 36.20 ± 3.82, which was higher than that in the control group (31.26 ± 5.03) ( t = 4.63, P<0.05). Three months after the operation, the self-care ability score of the observation group was 123.57 ± 10.82, which was higher than that of the control group (108.23 ± 9.48) ( t = 6.31, P<0.05). One month and three months after stoma retraction, the anal function scores of the observation group were 12.03 ± 3.94, 5.91 ± 2.05 respectively, which were lower than those of the control group (13.86 ± 2.19, 7.26 ± 1.74) ( t = 2.40, 2.99, both P<0.05). Conclusion:Pelvic floor muscle functional exercise based on Snyder′s hope theory can improve the hope level of patients after stoma retraction, improve their anal function and improve their self-care ability.
