ObjectiveTo investigate the effect of cerebellar intermittent theta-burst stimulation (iTBS) on postural control and fall risk in stroke patients. MethodsFrom October, 2024 to August, 2025, 45 stroke patients were recruited from Huadong Hospital Affiliated to Fudan University. They were randomly divided into control group (n = 15), group A (n = 15) and group B (n = 15). All the groups received conventional medication and rehabilitation. Group A was additionally administered iTBS over the ipsilesional primary motor cortex (M1), while group B received iTBS over the contralesional cerebellum, for three weeks. Before and after intervention, postural stability indexes (eyes open/closed), limits of stability, directional control score and reaction time were measured using Biodex Balance System, and they were assessed with Berg Balance Scale (BBS), Timed Up & Go Test (TUGT) and 10-meter walk test (10MWT). ResultsAfter intervention, significant group-time interaction effects were observed for eyes open/closed postural stability indexes, limits of stability, directional control score, reaction time, BBS score, TUGT and 10MWT (F > 23.487, P < 0.001). All the groups improved in all the indexes after intervention (P < 0.01). The eyes open/closed postural stability indexes, limits of stability, directional control score and reaction time were the best in group B, followed by group A, and the worst in the control group (P < 0.05), while BBS, TUGT and 10MWT were better in groups A and B than in the control group (P < 0.05). ConclusionCerebellar iTBS can effectively improve postural control disorders and reduce fall risk in stroke patients, and may be superior to M1 iTBS.

Oral squamous cell carcinoma (OSCC) is a common head and neck malignancy. Approximately 50% to 60% of patients with OSCC are diagnosed at a locally advanced stage (clinical staging III-IVa). Even with comprehensive and sequential treatment primarily based on surgery, the 5-year overall survival rate remains below 50%, and patients often suffer from postoperative functional impairments such as difficulties with speaking and swallowing. Programmed death receptor-1 (PD-1) inhibitors are increasingly used in the neoadjuvant treatment of locally advanced OSCC and have shown encouraging efficacy. However, clinical practice still faces key challenges, including the definition of indications, optimization of combination regimens, and standards for efficacy evaluation. Based on the latest research advances worldwide and the clinical experience of the expert group, this expert consensus systematically evaluates the application of PD-1 inhibitors in the neoadjuvant treatment of locally advanced OSCC, covering combination strategies, treatment cycles and surgical timing, efficacy assessment, use of biomarkers, management of special populations and immune related adverse events, principles for immunotherapy rechallenge, and function preservation strategies. After multiple rounds of panel discussion and through anonymous voting using the Delphi method, the following consensus statements have been formulated: 1) Neoadjuvant therapy with PD-1 inhibitors can be used preoperatively in patients with locally advanced OSCC. The preferred regimen is a PD-1 inhibitor combined with platinum based chemotherapy, administered for 2-3 cycles. 2) During the efficacy evaluation of neoadjuvant therapy, radiographic assessment should follow the dual criteria of Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1 and immune RECIST (iRECIST). After surgery, systematic pathological evaluation of both the primary lesion and regional lymph nodes is required. For combination chemotherapy regimens, PD-L1 expression and combined positive score need not be used as mandatory inclusion or exclusion criteria. 3) For special populations such as the elderly (≥ 70 years), individuals with stable HIV viral load, and carriers of chronic HBV/HCV, PD-1 inhibitors may be used cautiously under the guidance of a multidisciplinary team (MDT), with close monitoring for adverse events. 4) For patients with a poor response to neoadjuvant therapy, continuation of the original treatment regimen is not recommended; the subsequent treatment plan should be adjusted promptly after MDT assessment. Organ transplant recipients and patients with active autoimmune diseases are not recommended to receive neoadjuvant PD-1 inhibitor therapy due to the high risk of immune related activation. Rechallenge is generally not advised for patients who have experienced high risk immune related adverse events such as immune mediated myocarditis, neurotoxicity, or pneumonitis. 5) For patients with a good pathological response, individualized de escalation surgery and function preservation strategies can be explored. This consensus aims to promote the standardized, safe, and precise application of neoadjuvant PD-1 inhibitor strategies in the management of locally advanced OSCC patients.

This article describes a new species of Genus Xenodaeria Jordan(1932)(Siphonaptera: Ctenophthalmidae), collected from the southern slope of Cangshan mountain in Dali, Yunnan. The new species is similar to Xenodayia telios, Jordan 1932, and X. laxiproceria Wu, Gu et Liu,1996, but more like X. telios. However, it can be distinguished from X. telios and other known species in the genus based on the following characteristics: The movable process of the male gripper is bent finger shaped, with a blunt end and no angular protrusion extending forward; The posterior St. VII in females has a semi-circular deep depression, with blunt rounded ends of the dorsal and ventral lobes, and the dorsal lobes are wider and longer than the ventral lobes. The type specimen was collected on November 2,1994 from the shrubbery at an altitude of approximately 2 450 m in the southern end of Cangshan Mountain in Dali City, Yunnan Province. The host species were Anourosorex squamipes and Crocidura rapax.

A convenience sampling method was employed to recruit 445 food service employees from 67 Chinese restaurants across all 16 administrative districts of Beijing City from August to December in 2022. A questionnaire survey was conducted to assess their knowledge, attitudes, and behaviors regarding salt reduction and hypertension. The results revealed that awareness was highest for the statement "Hypertensive patients should reduce salt intake" (88.3%), while awareness of "China′s diagnostic criteria for hypertension" was the lowest (23.8%). Positive attitude endorsement rates were 96.0% for willingness to reduce salt, 95.3% for perceived self-efficacy in salt reduction, and 93.0% for agreement with a low-salt diet. Regarding behaviors, the rates of actively reducing salt when ordering takeout or dining out, using low-sodium salt, and using salt-reducing spoons were 73.7%, 45.4%, and 55.5%, respectively. The overall compliance rate for salt-reduction related behaviors was 73.9%. Multivariable logistic regression analysis demonstrated that: compared to the 18-29 age group, employees aged 30-39 ( OR=2.19, 95% CI: 1.16-4.14), 40-49 ( OR=3.36, 95% CI: 1.52-7.42), and 50-59 ( OR=3.25, 95% CI: 1.25-8.50) were significantly more likely to achieve compliance with salt-reduction behaviors; chefs were significantly more likely to achieve behavioral compliance compared to managerial staff ( OR=2.08, 95% CI: 1.08-3.98); employees in catering with adequate knowledge about salt reduction and hypertension were significantly more likely to exhibit behavioral compliance compared to those with inadequate knowledge ( OR=3.32, 95% CI: 1.83-5.92); employees in catering with positive attitudes towards salt reduction were significantly more likely to achieve behavioral compliance compared to those with negative attitudes ( OR=5.81, 95% CI: 2.05-16.43). In conclusion, food service employees in Beijing exhibit insufficient knowledge about salt intake and hypertension. While they demonstrate strong willingness to reduce salt, this does not consistently translate into action. Compliance with salt-reduction behaviors is influenced by age, education level, and job position. There is an urgent need to strengthen the dissemination of knowledge regarding high salt intake and hypertension and to implement personalized interventions targeting salt-reduction behaviors and skills.

Objective:To explore the implementation effect of the"four-step teaching of encouraging and sharing"combined anchor-based teaching mode in the course of laboratory diagnostics under the background of automatic laboratory.Methods:The"four-step teaching of encouraging and sharing"combined anchor-based teaching mode conducted teaching in course of laboratory diagnostics through carefully designed"anchors",self-directed learning,a second"anchor"placement,and outcome sharing.A total of 224 medical students of the 2021 and 2022 grades,who majored Chinese medicine in Beijing University of Chinese Medicine and conducted their internships in the Laboratory of Dongfang Hospital,Beijing University of Chinese Medicine from April 2023 to April 2025,were selected.According to different teaching modes,the 108 medical students of 2022 grade were divided into the combined teaching group that adopted the"four-step teaching of encouraging and sharing"combined anchor-based teaching mode to conduct teaching,and 116 medical students of 2021 grade were divided into the conventional teaching group that adopted conventional teaching mode to conduct teaching.After completed the courses,the comprehensive competency of these students of two groups during the internship were measured,and the application effect of the"four-step teaching of encouraging and sharing"combined anchor-based teaching mode was assessed by self-made survey questionnaire.Results:The scores of theoretical knowledge test and clinical case analysis assessment of the students of combined teaching group were respectively(44.19±2.36)and(48.20±1.52),all of which were higher than(38.36±2.14)and(37.56±2.47)of conventional teaching group,and the differences of them between two groups were statistically significant(t=28.72,55.71,P<0.05),respectively.In the combined teaching group,91.67%of the students expressed a preference for the"four-step teaching of encouraging and sharing"combined anchor-based teaching mode.Conclusion:Under the background of automatic laboratory,the"four-step teaching of encouraging and sharing"combined anchor-based teaching mode of laboratory diagnostics can effectively enhance students'transfer ability for knowledge,and strengthen their self-directed learning awareness,and lay a solid foundation for training clinical practice abilities of medical students.

Objective To examine the changing prevalence and antimicrobial resistance profiles of Burkholderia cepacia in 52 hospitals across China from 2015 to 2021.Methods A total of 9 261 strains of B.cepacia were collected from 52 hospitals between January 1,2015 and December 31,2021.Antimicrobial susceptibility of the strains was tested using Kirby-Bauer method or automated antimicrobial susceptibility testing systems according to a unified protocol.The results were interpreted according to the breakpoints released in the Clinical & Laboratory Standards Institute(CLSI)guidelines(2023 edition).Results A total of 9 261 strains of B.cepacia were isolated from all age groups,especially elderly patients.The proportion was 11.1％(1 032 strains)in children,significantly lower than the proportion in adults.About half(46.5％,4 310/9 261)of the strains were isolated from patients at least 60 years old and 42.3％(3 919/9 261)of the strains were isolated from young adults.Most isolates(71.1％)were isolated from sputum and respiratory secretions,followed by urine(10.7％)and blood samples(8.1％).B.cepacia isolates were highly susceptible to the five antimicrobial agents recommended in the CLSI M100 document(33rd edition,2023).B.cepacia isolates showed relatively higher resistance rates to meropenem and levofloxacin.However,the resistance rates to ceftazidime,trimethoprim-sulfamethoxazole,and minocycline remained below 8.1％.The percentage of B.cepacia strains resistant to levofloxacin was the highest compared to other antibiotics in any of the three age groups(from 12.4％in the patients＜18 years old to 20.6％in the patients aged 60 years or older).Conclusions B.cepacia is one of the clinically important non-fermenting gram-negative bacteria.Accurate and timely reporting of antimicrobial susceptibility test results and ongoing antimicrobial resistance surveillance are helpful for rational prescription of antimicrobial agents and proper prevention and control of nosocomial infections.

Breast cancer is the leading cause of cancer-related mortality among women worldwide and has drawn extensive research attention.Owing to its molecular heterogeneity,drug resistance,and low therapeutic response,single-modality treatments often fail to achieve satisfactory efficacy or broad applicability.Combination therapy,designed based on the pathophysiological characteristics,related signaling pathways,and biomarkers of breast cancer,has emerged as a promising approach for improving therapeutic outcomes.With the advancement of research on combination strategies,the understanding of their molecular mechanisms—particularly key signaling pathways and biomarkers—has become increasingly important.However,comprehensive reviews addressing these molecular mechanisms and synergistic strategies remain scarce.This article summarizes recent advances in combination therapy for breast cancer,providing a comprehensive review of recent combination therapies for breast cancer and their underlying molecular mechanisms,and focusing on key signaling pathways involved in combination therapy and synergistic strategies,thereby providing theoretical insights and reference for researchers,graduate students,and clinicians engaged in the development of novel combination therapeutic strategies for breast cancer and related malignancies.

Objective:To understand the tobacco use situation and related factors among the occupational population in Beijing in 2018.Methods:The data were obtained from a special survey on “Healthy Beijing People—Ten-year Action Plan for Health Promotion (2009—2018)”. From June to September 2018, 12 908 participants were recruited from 16 districts of Beijing using the stratified sampling method combined with the typical sampling method. Questionnaires were conducted to collect basic information, work situations, tobacco exposure in public places, and smoking cessation. The Chi-square test was used to compare the differences in current smoking rates, smoking cessation rates and second-hand smoke exposure rates among participants with different characteristics. Multivariate logistic regression analysis was used to analyze the related factors of tobacco use.Results:The present smoking rate of the occupational population in Beijing was 18.0% (95% CI: 17.3%-18.7%), and the passive smoking exposure rate of non-smokers was 61.0% (95% CI: 60.1%-61.9%). The smoking cessation rate among the working population was 22.2% (95% CI: 20.7%-23.7%), and the proportion of current smokers with the intention to quit was 63.9% (1 485/2 325). The present smoking rate of employees of different genders, ages, education levels and occupational nature showed statistically significant differences ( P<0.05). The results of multivariate logistic regression analysis showed that in males, compared with the age group of 16-29 years old, the risk of smoking increased in the age groups of 30-39 years old, 40-49 years old and over 50 years old [ OR (95% CI) values were 1.49 (1.27-1.74), 1.34 (1.13-1.59) and 1.30 (1.06-1.59)]. Compared with those with junior high school or lower education, participants with high school/vocational/college education group had a higher risk of smoking ( OR=1.38, 95% CI: 1.13-1.69), while those with master′s degree or above had a lower risk of smoking ( OR=0.30, 95% CI: 0.22-0.42). The physical workers ( OR=1.28, 95% CI: 1.11-1.47) had a higher risk of smoking than the mental workers. Conclusion:The current smoking rate among the occupational population in Beijing is lower than the national level during the same period, but the exposure rate to second-hand smoke is relatively high. Age, educational level, job nature and gender are related factors of smoking.
