ObjectiveTo investigate and manage an imported dengue fever (DF) outbreak in Shanghai in 2024, to summarize the experience and lessons learned from the on-site management, and to provide a reference basis for future prevention and control of DF. MethodsEpidemiological investigation and case search were carried out for an imported DF outbreak in Shanghai, 2024. Real-time fluorescence polymerase chain reaction (RT-PCR) was used to detect dengue virus nucleic acid in the serum samples from cases. Meanwhile, emergency vector surveillance and mosquito control measures were carried out in the affected areas, and the effectiveness of the management was evaluated. ResultsAccording to the epidemiological investigation, it was confirmed that this epidemic was a family cluster of imported DF, with both cases infected in Thailand and developed symptoms successively after returning to Shanghai. Laboratory testing identified the pathogens as dengue virus serotype-3 (DENV-3). In the core and precautionary area, ultra-low-volume space spraying and residual spraying were combined to kill adult mosquitoes, and at the same time, comprehensive cleaning and elimination of mosquito breeding sites was carried out. After 2 weeks, the Breteau Index (BI) in the core area decreased from 20 to 5, and the mosquito net trap index decreased from 2 mosquitoes (net·hour)-1 to 0.67 mosquitoes (net·hour)-1. Continuous implementation of mosquito control measures kept the BI and net trap index below the safety thresholds [BI<5 and mosquito net trap index <2 mosquitoes (net·hour)-1] both in the core and precautionary area. ConclusionEarly diagnosis and isolation of patients, combined with rapid suppression of the density of vector Aedes mosquitoes, are the key measures to prevent the transmission of imported DF cases.

ObjectiveTo decipher the mechanism by which Zuoguiwan (ZGW) treat hyperthyroidism in rats with kidney-Yin deficiency based on the dopamine receptor D4 (DRD4)/nicotinamide adenine dinucleotide phosphate (NADPH) oxidase 4 (NOX4) signaling pathway. MethodsThe rat model of kidney-Yin deficiency was induced by unilateral intramuscular injection of dexamethasone (0.35 mg·kg-1). After successful modeling, the rats were randomized into model, methimazole (positive control, 5 mg·kg-1), low-, medium-, and high-dose (1.85, 3.70, 7.40 g·kg-1, respectively) ZGW, and normal control groups. After 21 days of continuous gavage, the behavioral indexes and body weight changes of rats were evaluated. The pathological changes of the renal tissue were observed by hematoxylin-eosin staining. The serum levels of thyroid hormones [triiodothyronine (T3), thyroxine (T4), thyroid-stimulating hormone (TSH)], renal function indexes [serum creatine (Scr) and blood urea nitrogen (BUN)], energy metabolism markers [cyclic adenosine monophosphate (cAMP) and cyclic guanosine monophosphate (cGMP)], and oxidative stress-related factors [superoxide dismutase (SOD), malondialdehyde (MDA), and NADPH)] were measured by enzyme-linked immunosorbent assay (ELISA). Western blot was employed to analyze the expression of DRD4, NOX4, mitochondrial respiratory chain complex proteins [NADH:ubiquinone oxidoreductase subunit S4 (NDUFS4) and cytochrome C oxidase subunit 4 (COX4)], and inflammation-related protein [tumor necrosis factor-alpha (TNF-α), interleukin-6 (IL-6), p38 mitogen-activated protein kinase (MAPK)] pathway in the renal tissue. ResultsCompared with the normal group, the model group showed mental malaise, body weight decreases (P<0.01), inflammatory cell infiltration in the renal tissue, a few residual parotid glands in the thyroid, elevations in serum levels of T3, T4, Scr, BUN, cAMP, cAMP/cGMP, MDA, and NADPH (P<0.01), down-regulation in protein levels of TSH, SOD, and DRD4 (P<0.05, P<0.01), and up-regulation in expression of NOX4, p-p38 MAPK/p38 MAPK, and inflammatory factors (P<0.01). Compared with the model group, ZGW increased the body weight (P<0.05, P<0.01), reduced the infiltration of renal interstitial inflammatory cells, restored the thyroid structure and follicle size, lowered the serum levels of T3, T4, Scr, BUN, cAMP, cAMP/cGMP, MDA and NADPH (P<0.05, P<0.01), up-regulated the expression of TSH, SOD and DRD4 (P<0.05, P<0.01), and down-regulated the expression of NOX4, p-p38 MAPK/p38 MAPK, and inflammatory factors (P<0.05, P<0.01). Moreover, high-dose ZGW outperformed methimazole (P<0.05). ConclusionBy activating DRD4, ZGW can inhibit the expression of NOX4 mediated by the p38 MAPK pathway, reduce oxidative stress and inflammatory response, thereby ameliorating the pathological state of hyperthyroidism due to kidney-Yin deficiency. This study provides new molecular mechanism support for the clinical application of ZGW.

In recent years, traditional Chinese medicine (TCM) has achieved significant progress in the treatment of inflammatory bowel disease (IBD). A comprehensive literature search was conducted covering the period from January 1, 2010, to December 30, 2024, across Chinese databases including China National Knowledge Infrastructure (CNKI), Wanfang Data, VIP China Science and Technology Journal Database, and the Chinese Biomedical Literature Service System, as well as international databases such as PubMed, Web of Science, and Embase. The clinical applications and mechanistic studies of TCM in IBD were systematically reviewed. The current status of TCM research on the etiology and pathogenesis of IBD, innovative clinical practices, and multimodal therapeutic approaches, including Chinese herbal formulas, single herbs or active compounds, acupuncture, herbal retention enema, and acupoint application, were summarized, together with their synergistic effects when combined with western medical treatments. The development and application of Chinese patent medicines for IBD are undergoing a profound transition from efficacy validation to mechanistic exploration. Mechanistic studies on the effects of TCM in IBD mainly focus on regulating gut microbiota homeostasis, repairing the intestinal mucosal barrier, and modulating intestinal immune balance. Furthermore, future research directions for TCM-based IBD management are proposed, including the establishment of TCM diagnostic and treatment models, expanding integrated applications of external and internal TCM therapies, innovating personalized treatment strategies, and advancing drug development. These efforts aim to provide insights for the standardized and precision-oriented development of TCM in the diagnosis and treatment of IBD.

Objective:
Inflammatory cascade reactions play a crucial role in secondary neuronal injury in acute ischemic stroke (AIS). The aim of this study was to explore the correlations between specific serological indicators, early neurological deterioration (END), disease prognosis, and syndrome factors in AIS based on this injury mechanism.
Methods:
The data for this study were collected from 135 patients with AIS admitted to the emergency department of Fangshan Hospital, Beijing University of Chinese Medicine, within 24 h of onset between November 2019 and May 2021. Among these, 29 patients had complete data and experienced END. Additionally, 9 non-END patients were matched from the remaining 90 patients with complete data, resulting in a total of 38 patients for statistical analysis. Statistical methods, including logistic regression and receiver operating curves, were used to analyze the correlation between serum levels of tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), interleukin-10 (IL-10), vascular endothelial growth factor (VEGF), and intercellular adhesion molecule-1 (ICAM-1) within 24 h of END onset, disease prognosis, and syndrome factors. Grouping criteria included END occurrence, presence of syndrome elements on the first and third day post-onset, and prognosis at 90 days post-onset.
Results:
All 38 cases had onset time of less than 12 h, and there were no significant differences in age, gender, and onset time between the END and non-END groups. The TNF-α serum level within 24 h of onset was not associated with the occurrence of END but was negatively correlated with all-cause mortality at 90 days [0.1

ObjectiveTo explore the effect of exercise on anxiety and depression in cancer patients during chemotherapy, as well as the optimal exercise dosage. MethodsA PICO framework was constructed, and randomized controlled trials (RCTs) on the effect of exercise on anxiety and depression in cancer patients during chemotherapy were retrieved from databases of PubMed, Web of Science, Cochrane Library, Embase, Medline, CNKI, VIP and Wanfang data, from the establishment to November, 2023. The quality of the literature was evaluated with Cochrane Risk of Bias Tool and Physiotherapy Evidence Database (PEDro) scale. Data were synthesized and analyzed using RevMan 5.3, and the risk of bias was evaluated using Stata 18.0. ResultsA total of 13 RCTs involving 1 340 subjects were included. The scores of PEDro scale were five to eight. Exercise interventions significantly improved anxiety (SMD = -0.70, 95%CI -1.18 to -0.22, P = 0.004) and depression (SMD = -0.89, 95%CI -1.43 to -0.34, P = 0.002) compared to the control group. Subgroup analyses showed that, the exercise effect on anxiety was less than 45 minutes a time (SMD = -0.26, 95%CI -0.46 to -0.05, P = 0.01), more than three times a week (SMD = -0.26, 95%CI -0.46 to -0.05, P = 0.01), and less than twelve weeks (SMD = -0.21, 95%CI -0.36 to -0.07, P = 0.005). For depression, it was less than 45 minutes a time (SMD = -0.69, 95%CI -1.29 to -0.08, P = 0.03), more than three times a week (SMD = -0.69, 95%CI -1.29 to -0.08, P = 0.03), and less than twelve weeks (SMD = -0.52, 95%CI -0.92 to -0.13, P = 0.01). Moderate to high-intensity exercise interventions significantly outperformed the control group in improving anxiety (SMD = -0.21, 95%CI -0.37 to -0.06, P = 0.007) and depression (SMD = -0.21, 95%CI -0.41 to -0.01, P = 0.04). ConclusionExercise interventions can effectively improve anxiety and depression in cancer patients during chemotherapy, and it suggests for high-intensity exercise, less than 45 minutes a time, more than three times a week, and less than twelve weeks.

Objective:
To investigate the situation and influencing factors of school bullying experienced by primary and middle school students, so as to provide the basis for formulating school bullying intervention measures and promoting students' physical and mental health development.
Methods:
All the counties (cities, districts) in Zhejiang Province were stratified to urban and suburban areas, primary, junior high and senior high school students were selected using a stratified cluster sampling method. Basic information, lifestyle and school bullying were collected through questionnaire surveys. Factors affecting school bullying experienced by primary and middle school students were analyzed using a multivariable logistic regression model.
Results:
Totally 137 846 valid questionnaires were recovered, with an effective recovery rate of 97.17%. There were 72 526 males (52.61%) and 65 320 females (47.39%). There were 47 561 primary school students (34.50%), 47 701 junior high school students (34.61%) and 42 584 senior high school students (30.89%). A total of 3 987 students suffered from school bullying, accounting for 2.89%. The proportions of being maliciously teased, being intentionally excluded from group activities/isolated, being teased about physical defects or appearance, being hit/kicked/pushed/shoved/locked in a room, being threatened, and being extorted for money were 2.04%, 1.18%, 1.11%, 0.86%, 0.84% and 0.83%, respectively. Multivariable logistic regression analysis showed that the students who were males (OR=1.122, 95%CI: 1.048-1.202), lived in suburban areas (OR=1.322, 95%CI: 1.233-1.418), lived in areas with medium (OR=1.086, 95%CI: 1.006-1.173) or underdeveloped (OR=1.298, 95%CI: 1.191-1.415) economic level, had higher academic levels (junior high school, OR=1.380, 95%CI: 1.270-1.499; senior high school, OR=1.210, 95%CI: 1.083-1.351), lived on campus (OR=1.489, 95%CI: 1.372-1.616), engaged in fights (OR=6.029, 95%CI: 5.585-6.509), attempted to smoke (OR=1.320, 95%CI: 1.128-1.545), drank (OR=1.735, 95%CI: 1.575-1.912), were scolded and beaten by parents (OR=1.972, 95%CI: 1.822-2.135) and were obese (OR=1.240, 95%CI: 1.132-1.360) were more likely to experience school bullying.
Conclusion
The harm of school bullying to the physical and mental health of primary and middle school students should be taken seriously, and active policy measures should be adopted to strengthen intervention.

Background and Aims:Biliary tract cancers(BTCs)are highly aggressive malignancies with dismal prognosis,for which radical resection remains the only potentially curative treatment.Laparoscopic surgery has demonstrated superiority over open surgery in perioperative safety and recovery,yet it is technically limited in complex operations.Robot-assisted laparoscopy,with its high-definition three-dimensional vision and enhanced instrument dexterity,may overcome these limitations.However,comparative evidence balancing baseline differences between laparoscopic and robot-assisted laparoscopic radical resections for BTCs is still lacking.This study aimed to evaluate and compare their short-term safety using propensity score matching(PSM).Methods:A total of 151 patients with biliary tract cancers who underwent radical resection were retrospectively enrolled from the Chinese Biliary Tract Tumor Collaborative Group database,including 128 in the laparoscopic group and 23 in the robotic-assisted laparoscopic group.To balance baseline differences,an initial 1∶1 PSM was performed,yielding 19 laparoscopic and 19 robotic cases.Subsequently,using the robotic group as the reference,a 1∶2 PSM was conducted,resulting in 36 laparoscopic and 18 robotic cases.Primary outcomes(conversion to open surgery,ICU admission,and postoperative complications)and secondary outcomes(operative time,intraoperative blood loss,transfusion,postoperative hospital stay,reoperation,readmission,and hospitalization costs)were compared between the two groups.Multivariate regression analyses were performed to explore factors associated with conversion to open surgery and postoperative hospital stay.Results:After matching,baseline characteristics were well balanced between groups.For primary outcomes,the conversion rate to open surgery was significantly higher in the laparoscopic group than in the robotic group(41.7%vs.0,P=0.001),while ICU admission,overall postoperative complications,and Clavien-Dindo graded complications showed no significant differences(all P>0.05).For secondary outcomes,the postoperative hospital stay was significantly more extended in the laparoscopic group compared with the robotic group(18.5 d vs.8.0 d,P=0.005),whereas operative time,intraoperative blood loss,transfusion,reoperation,readmission,and hospitalization costs were comparable(all P>0.05).Logistic regression for conversion did not identify statistically significant predictors,but moderately differentiated tumors,elevated preoperative CA19-9,and higher harvested lymph node counts showed trends toward increased risk.Multivariate linear regression revealed that robotic-assisted surgery was an independent factor for reduced postoperative hospital stay(P=0.024),while preoperative total bilirubin(P=0.020),longer operative time(P=0.000),postoperative complications(P=0.006),and reoperation(P=0.005)were found to be associated with a prolonged hospital stay.Conclusion:Robot-assisted laparoscopic radical resection for BTCs is not inferior to conventional laparoscopy in short-term safety and may further reduce conversion rates and hospital stay.Its technical advantages may be particularly valuable in anatomically complex or challenging cases.Nonetheless,cost-effectiveness and resource allocation should be considered for wider adoption.
