ObjectiveTo analyze the incidence and trend of stroke in Beilun District, so as to provide evidence for identifying influencing factors and reducing stroke incidence. MethodsStroke cases from 2012 to 2023 were extracted from the Ningbo Chronic Disease Collaborative Management System. Population information of Beilun District during the same period was also collected. The annual incidence and trends of stroke were analyzed. ResultsFrom 2012 to 2023, the age-standardized incidence rate of stroke in Beilun District, Ningbo City was 317.68/100 000, showing an increasing trend with an average annual percentage change (AAPC) of 2.267% (P=0.034). Among all subdistricts in Beilun District, two showed a downward trend in incidence, while the rest showed an upward trend. The crude incidence rate of stroke was significantly higher in males than that in females (P<0.001). The age-standardized incidence rate in males was 406.08/100 000, showing an increasing trend (AAPC=3.956%, P<0.001). The incidence of stroke also showed an increasing trend in the following age groups: 30‒<45 years (AAPC=6.340%, P=0.004), 45‒<60 years (AAPC=4.997%, P<0.001), and 60‒<75 years (AAPC=3.282%, P=0.042). Across all years, males had higher crude incidence rates in both ischemic and hemorrhagic stroke than females (P<0.05). The age-standardized incidence rate of ischemic stroke showed a rising trend in both males and the general population (male AAPC=4.905%, P<0.001; overall population AAPC=3.065%, P=0.001). ConclusionThe age-standardized incidence of stroke in Beilun District is on the rise, with higher crude incidence rate in males than that in females. The onset age of stroke is gradually declining. The age-standardized incidence rate of male ischemic stroke shows a clear upward trend.

ObjectiveTo evaluate the efficacy and safety of Xiaoji Hufei Formula in protecting children with close contact exposure to influenza， and to provide reference and evidence-based support for better clinical prevention and treatment of influenza in children. MethodsA multicenter， prospective， non-randomized， parallel， controlled trial was conducted from October 2021 to May 2022 in five hospitals， including Dongfang Hospital of Beijing University of Chinese Medicine. Confirmed influenza cases and influenza-like illness （ILI） cases were collected， and eligible children with close contact exposure to these cases were recruited in the outpatient clinics. According to whether the enrolled close contacts were willing to take Xiaoji Hufei formula for influenza prevention， they were assigned to the observation group （108 cases） or the control group （108 cases）. Follow-up visits were conducted on days 7 and 14 after enrollment. The primary outcomes were the incidence of ILI and the rate of laboratory-confirmed influenza. Secondary outcomes included traditional Chinese medicine （TCM） symptom score scale for influenza， influenza-related emergency （outpatient） visit rate， influenza hospitalization rate， and time to onset after exposure to influenza cases. ResultsA total of 216 participants were enrolled， with 108 in the observation group and 108 in the control group. Primary outcomes： （1） Incidence of ILI： The incidence was 12.0% （13/108） in the observation group and 23.1% （25/108） in the control group， with the observation group showing a significantly lower incidence （χ²=4.6， P<0.05）. （2） Influenza confirmation rate： 3.7% （4/108） in the observation group and 4.6% （5/108） in the control group， with no statistically significant difference. Secondary outcomes： （1） TCM symptom score scale： after onset， nasal congestion and runny nose scores differed significantly between the two groups （P<0.05）， while other symptoms such as fever， sore throat， and cough showed no significant differences. （2） Influenza-related emergency （outpatient） visit rate： 84.6% （11 cases） in the observation group and 96.0% （24 cases） in the control group， with no significant difference. （3） Time to onset after exposure： The median onset time after exposure to index patients was 7 days in the observation group and 4 days in the control group， with a statistically significant difference （P<0.05）. ConclusionIn previously healthy children exposed to infectious influenza cases under unprotected conditions， Xiaoji Hufei formula prophylaxis significantly reduced the incidence of ILI. Xiaoji Hufei Formula can be recommended as a specific preventive prescription for influenza in children.

ObjectiveTo explore the effectiveness of feedforward control mode on improving occupational burnout among operating room nurses through theoretical research and clinical practice， with a view to promoting their physical and mental health and enhancing the quality of surgical nursing. MethodsA total of 440 operating room nurses from different regions， scales， and nursing experiences in Shaanxi Province from November 2023 to December 2023 were randomly divided into an experimental group and a control group， with 220 nurses in each group. While the control group received routine intervention measures， the experimental group introduced a feedforward control mode based on the control group， with “emotional exhaustion，” “depersonalization，”and“personal achievement” as observation indicators. ResultsThe incidence of occupational burnout in the experimental group was 11.4%， while that in the control group was 20.0%. The experimental group showed a significantly lower incidence than the control group （P=0.013）. ConclusionThe feedforward control mode can significantly alleviate nurses’ sense of job burnout， promote the improvement of surgical nursing quality， as well as continuously improve the scientific rigor， advancement， and humanistic nature of nursing services， which is conducive to building a harmonious and efficient nursing team. The spirit of teamwork， reflected in mutual support， mutual trust， and joint efforts for surgical success and patient health， has become an important component of nurses’ professional ethics.

Objective To establish a stable,reliable,and clinically relevant porcine model of endotoxin-induced acute respiratory distress syndrome(ARDS).Methods Ten 8-month-old male Bama minipigs were deeply sedated,followed by invasive mechanical ventilation and electrocardiographic monitoring.Lipopolysaccharide(LPS)was intravenously pumped at 600 μg/(kg·h)for 3 hours,then maintained at 15 μg/(kg·h)thereafter.Dynamic monitoring was performed at five time points after LPS injection(LPS 0,1,3,5,and 8 h),including arterial blood gas analysis and chest computed tomography(CT)scans.Pathological examination of lung tissues obtained via bronchoscopic biopsy(HE staining and transmission electron microscopy)was conducted.These indicators were comprehensively used to evaluate the success of the animal model.Results At 5 hours after LPS administration,8 minipigs developed symptoms such as skin cyanosis,elevated body temperature,and respiratory distress.The oxygenation index decreased to<300 mmHg.Chest CT scans showed diffuse pulmonary infiltrates.Histopathology revealed alveolar edema and hyaline membrane formation.Transmission electron microscopy demonstrated disruption of pulmonary blood-air barrier,depletion of lamellar bodies in type Ⅱ pneumocytes,inflammatory cell infiltration,and exudation of plasma proteins and fibrin.Compared with LPS 0 h,at LPS 8 h,the oxygenation index and arterial blood pH were significantly decreased(P<0.001),while blood lactic acid and serum potassium were significantly increased(P<0.05);serum calcium and base excess were significantly decreased(P<0.05),and the lung injury score based on HE-stained lung sections was significantly increased(P<0.01).Conclusion The porcine ARDS model established by continuous LPS injection can dynamically simulate the pathophysiological characteristics and typical pathological manifestations of clinical septic ARDS,making it an effective tool to study the pathogenesis,prevention,and treatment strategies of septic ARDS.

To address the economic challenge associated with acquiring labeled sample data for white paeony,a semi-supervised learning model based on metric learning and consistency constraints was proposed to predict the content of trace heavy metal pollutants Pb and Cd in white paeony.The model was comprised of two multi-task deep learning networks with the same structure but different parameters,namely the teacher model and the student model.The multi-task deep learning network utilized metric learning within the classification branch to ensure the clustering of different samples,thereby enhancing the predictive performance of the regression branch for heavy metal content in white peony samples.The student model effectively utilized unlabeled data by constraining the consistency of outputs between the teacher and student models.Experimental results showed that the proposed multi-task deep learning network combined with the regression subnetwork model significantly reduced the average relative errors of Pb and Cd in the test set to 7.01%and 8.16%when predicting trace heavy metal pollutants in paeony.Furthermore,after integrating the metric learning loss function-constrained and the consistency-constrained teacher-student semi-supervised learning model,the same samples exhibited clustering phenomena,with faster convergence speed and convergence values closer to 0 in the loss function,reducing the average relative errors of Pb and Cd in the test set to 3.32%and 4.77%.The above results indicated that the model proposed in this work could effectively enhance the accuracy and reliability of LIBS in quantitative analysis of trace heavy metal elements in paeony,strengthening the advantages of LIBS in practical applications for quality supervision in the traditional Chinese medicine market.

OBJECTIVE: To observe the clinical effect of acupuncture-moxibustion therapy of Daoqi Tongluo (conducting qi and unblocking collateral) on chronic primary tinnitus. METHODS: A total of 32 patients with chronic primary tinnitus were included and treated with the acupuncture-moxibustion therapy of Daoqi Tongluo. This regimen was composed of abdominal acupuncture, body acupuncture, warm needling and posterior-auricular local flashing cupping, Zhongwan (CV12), Guanyuan (CV6) and Yindu (KI9), Tinggong (SI19), Cong'er point, Waiguan (TE5) of the affected side, etc. are selected. The treatment was given once every two days, 3 treatments a week; and one course of intervention was required, with 10 treatments included. Before and after treatment, the scores of tinnitus handicap inventory (THI), tinnitus evaluation questionnaire (TEQ), self-rating scale of sleep (SRSS), self-rating anxiety scale (SAS), and self-rating depression scale (SDS) were observed, and the clinical effect was evaluated. RESULTS: After interventions, the scores of THI, TEQ, SRSS, SAS and SDS were reduced in comparison with those before interventions in the patients (P<0.001, P<0.01, P<0.05), and the total effective rate was 71.9% (23/32). CONCLUSION Acupuncture-moxibustion therapy of Daoqi Tongluo is effective on chronic primary tinnitus and this therapy can alleviate tinnitus degree, improve sleep quality and attenuate the anxious and depressive emotion of the patients.

Objective:To investigate the relationship between different states of cardiac function and their changes during the course of diabetic foot ulcers(DFU), and to evaluate their impact on patient prognosis.Methods:A retrospective analysis was conducted on 194 DFU patients who were rehospitalized at approximately 3-month intervals. Basic clinical data and cardiac function-related indicators were collected at baseline and follow-up. Patients were followed until death or until November 10, 2024. Outcomes including ulcer healing, recurrence, minor amputation, and death were recorded. Logistic regression models were used to analyze the effects of cardiac function status and its changes on these four outcomes. Results:After treatment, the proportion of patients with NYHA class Ⅱ-Ⅲ decreased significantly from 33.5% at baseline to 21.6%( P=0.009). Serum N-terminal pro-B-type natriuretic peptide(NT-proBNP) level also decreased after treatment compared with baseline [635.85(59.83, 453.28) pg/mL vs 728.67(81.48, 696.15) pg/mL, P=0.055]. Serum NT-proBNP level was significantly higher in the death group compared to the survival group( P=0.002). The proportion of DFU patients with baseline NYHA class Ⅱ-Ⅲ was significantly higher than that in those with class Ⅰ( P=0.012). Regression analysis showed that an improvement in NT-proBNP levels was associated with a lower risk of DFU recurrence( OR=0.378, 95% CI 0.183-0.779, P=0.008), and improvement in NYHA class was associated with a lower mortality risk( OR=0.074, 95% CI 0.020-0.275, P<0.001). Conclusion:Cardiac function status and its changes during the treatment of DFU patients have strong prognostic implications, particularly in predicting the risk of recurrence and death outcomes.

Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.

Objective:To investigate the dynamic characteristics of human papillomavirus (HPV) genomic integration during cervical lesion progression and the clinical value of HPV integration detection in stratify HPV-positive women, and to explore its molecular mechanisms in cervical carcinogenesis.Methods:A prospective cohort study was designed to enroll high-risk HPV (HR-HPV) positive women who underwent cervical cancer screening in Drum Tower Hospital Affiliated to Nanjing University Medical School and Nanjing Maternity and Child Health Care Hospital from July 2022 to July 2024. Cervical exfoliated cells samples were collected, and HPV whole genome targeted capture and high-throughput sequencing technology were used. The HPV integration patterns, host gene functional region distribution and pathway enrichment characteristics of 157 samples with different cervical lesions grades were analyzed, including 31 cases of normal cervix, 40 cases of cervical intraepithelial neoplasia (CIN) Ⅰ, 32 cases of CIN Ⅱ, 42 cases of CIN Ⅲ, and 12 cases of cervical cancer.Results:HR-HPV integration was detected in 80.2% (126/157) of the 157 HR-HPV positive samples. The incidence of HR-HPV integration in cervical cancer patients was 12/12, which was higher than that in normal women (77%, 24/31). The incidence of HPV16 integration was significantly higher in high-grade lesions, and the incidence of HPV16 integration was 43% (18/42) in CIN Ⅲ patients and 8/12 in cervical cancer patients ( P<0.001). A total of 14 438 integration events were detected in 126 samples with HPV integration. The integration sites were mainly distributed in the host intergenic region (51.0%, 7 359/14 438) and intronic region (38.1%, 5 494/14 438), and the integration frequency of viral L1 gene was the highest (28.4%, 4 498/16 781). Functional enrichment analysis showed that HPV integration-related host genes were significantly enriched in transport of small molecules,cyclic guanosine monophosphate (cGMP)-protein kinase G (PKG) signaling pathway, and purine ribonucleotide biosynthetic process, which synergistically drove carcinogenesis through multiple mechanisms. Conclusions:HPV integration events are significantly associated with the progression of cervical lesions. HPV integrated detection based on cervical exfoliated cells is expected to optimize the current screening strategy, reduce excessive intervention of HPV positive women and facilitate their accurate triage management.
