Objective To comprehensively analyze the current epidemic characteristics and disease burden of brucellosis in Tongliao City, and to provide a basis for the prevention and control strategy of brucellosis in Tongliao City. Methods The report data of brucellosis in Tongliao City from 2018 to 2023 were collected. Descriptive methods were used for data analysis, and the disability-adjusted life years and indirect economic losses were calculated. Results From 2018 to 2023, a total of 22 034 cases were reported in Tongliao City, with an average annual incidence of 136.17/100 000. The incidence was statistically different between men and women ( χ²=12.23, P=0.032). The majority of cases were farmers (94.25%), followed by herdsmen (1.67%). The age group was concentrated between 30-60 years old (79.30%), among which the majority of cases were in the 40-50 years group (6 883/22 034). The onset time had seasonal characteristics, and the peak period was from March to August (the seasonal index was between 115.40%-151.29%). In terms of regional distribution, cases were reported in all counties (banners). The average annual incidence was highest in Kulun Banner (233.85/100 000) and Zalut Banner (210.13/100 000), and lowest in Keerqin District (42.28/100 000) and Holingol City (31.87/100 000). The analysis of disease burden showed that a total of 677.55 person-years (YLD) were lost from 2018 to 2023, with an average annual loss of 112.92 person-years. The total indirect economic loss was 59.3576 million yuan, with an average annual loss of 9.892 9 million yuan, and the people over 60 years old had the lowest annual loss. Conclusion The overall brucellosis epidemic in Tongliao City has shown a fluctuating downward trend. The epidemic prevention and control should be strengthened in farmers, people aged 40-50 years old, and areas such as Zalut Banner and Kulun Banner to further control the epidemic of brucellosis.

By reviewing the physical biological research on the activation of acupoint effects by acupuncture， this paper explains the activation mechanism from the perspective of the generation and transmission of mechanical signals caused by acupuncture， and reveals the physical-chemical coupling processes in the acupoint microenvironment. Future research should focus on locally mechanosensitive cells， further exploring how acupuncture mechanical signals trigger dynamic changes in cells and molecules in the acupoints， and the physical-chemical information transduction mechanism， which will provide scientific evidence for the acupoint activation during acupuncture. Related studies will contribute to a deeper understanding of the scientific principles behind acupuncture and promote its clinical application and development.

Objective To systematically evaluate the risk prediction models for postoperative pulmonary infection in patients with esophageal cancer, providing an objective basis for clinical selection and optimization of models. Methods A systematic search was conducted in Chinese and English databases such as VIP, Wanfang, CNKI, CBM, PubMed, Cochrane Library, Embase, and Web of Science for studies related to the risk prediction models of postoperative pulmonary infection in patients with esophageal cancer from the inception to September 30, 2024. The PROBAST tool was used to assess the quality of prognostic model research, and the RevMan 5.4 software was used for meta-analysis of predictive factors. Results A total of 17 articles were included, containing 26 pulmonary infection risk prediction models. The area under the receiver operating characteristic curve (AUC) ranged from 0.627 to 0.942, among which 21 models had good predictive performance (AUC>0.7). Quality assessment through the PROBAST tool revealed that all 17 articles had a high risk of bias. Meta-analysis results showed that common predictive factors for postoperative pulmonary infection in esophageal cancer included smoking history (OR=1.97), smoking index ≥200 (cigarettes-years) (OR=4.38), smoking index ≥400 (cigarettes-years) (OR=2.00), age (OR=1.27), comorbid diabetes (OR=2.13), comorbid emphysema or chronic obstructive pulmonary disease (OR=1.55), low plasma albumin levels (OR=1.17), prognostic nutritional index (OR=4.45), history of related lung diseases (OR=2.10), tumor location (OR=2.32), surgical approach (OR=2.21), operation time (OR=1.73), preoperative serum procalcitonin levels (OR=3.06), anastomotic leakage (OR=3.39), reduced forced expiratory volume in the first second/forced vital capacity ratio (OR=0.86), and hoarseness (OR=2.23). Conclusion At present, the risk prediction models for postoperative pulmonary infection in esophageal cancer are still in the stage of continuous development and optimization, and their research quality needs to be further improved. Future research can refer to the predictive factors summarized in this study based on meta-analysis, combined with clinical practice, to select appropriate methods to construct and validate the risk prediction models for postoperative pulmonary infection in esophageal cancer, thus providing early targeted preventive strategies for high-risk patients.

AIM: To investigate factors associated with anterior chamber exudation following phacoemulsification combined with intraocular lens(IOL)implantation.

METHODS: Clinical data from patients with cataract who underwent phacoemulsification combined with IOL implantation at the hospital between June 2021 and June 2025 were retrospectively analyzed. Patients were divided into an exudation group and a non-exudation group according to the presence or absence of postoperative anterior chamber exudation. Demographic characteristics, underlying diseases, preoperative examination findings, surgery-related factors, intraoperative complications, and postoperative conditions were collected and compared between the two groups. Factors associated with anterior chamber exudation after phacoemulsification combined with IOL implantation were analyzed.

RESULTS: A total of 840 cataract patients(840 eyes)who underwent phacoemulsification combined with IOL implantation were enrolled. According to the presence or absence of postoperative anterior chamber exudation, 42 patients(42 eyes)were assigned to the exudation group, including 18 men and 24 women, with a mean age of 72.04±7.84 y; the remaining 798 patients(798 eyes)were assigned to the non-exudation group, including 370 men and 428 women, with a mean age of 65.13±9.25 y. Univariate analysis showed significant between-group differences in age, duration of cataract, diabetes mellitus, postoperative elevation of intraocular pressure, duration of corticosteroid eye-drop use, and lens nuclear grade(all P<0.05). Restricted cubic spline analysis demonstrated significant overall associations of age, duration of cataract, and duration of corticosteroid eye-drop use with the risk of postoperative anterior chamber exudation(all P<0.001). No significant non-linear associations were observed(P_{for non-linearity} >0.05), indicating linear relationships. Multivariable Logistic regression analysis showed that age(OR=1.096, 95%CI: 1.053-1.141), duration of cataract(OR=1.074, 95%CI: 1.042-1.107), diabetes mellitus(OR=2.630, 95%CI: 1.269-5.453), postoperative elevation of intraocular pressure(OR=4.311, 95%CI: 1.851-10.041), duration of corticosteroid eye-drop use(OR=2.082, 95%CI: 1.479-2.930), and lens nuclear grade ≥IV(OR=2.635, 95%CI: 1.309-5.304)were risk factors for postoperative anterior chamber exudation(all P<0.05). A nomogram prediction model was developed based on these factors. The calibration curve showed good agreement between the predicted and observed probabilities. ROC curve analysis showed that the AUC of the model for predicting postoperative anterior chamber exudation was 0.858(95%CI: 0.801-0.916), with a sensitivity of 0.810 and a specificity of 0.803.

CONCLUSION: Anterior chamber exudation following phacoemulsification combined with IOL implantation is influenced by multiple factors. Age, duration of cataract, diabetes mellitus, postoperative elevation of intraocular pressure, longer duration of corticosteroid eye-drop use, and greater lens nuclear hardness are risk factors. The nomogram developed using these factors demonstrates good predictive performance for postoperative anterior chamber exudation and may facilitate the early identification of high-risk patients and the development of individualized intervention strategies.

Endoscopic thoracic sympathicotomy/sympathotomy (ETS) is the first-line treatment for palmar hyperhidrosis with best minimally invasive effect. In recent years, with the widespread development of ETS in the treatment of palmar hyperhidrosis, many medical centers list ETS surgery as the day surgery. Nevertheless, there is no expert consensus on medical quality control of day surgery for ETS yet. Therefore, the Chinese Medical Doctor Association Thoracic Surgeons Branch Hyperhidrosis Subcommittee, Sympathetic Neurosurgery Expert Committee of WU Jieping Medical Foundation, and Fujian Provincial Strait Medical and Health Exchange Association Hyperhidrosis Special Committee organized domestic experts to conduct repeated consultations and sufficient discussions based on domestic and foreign literatures, to formulate the "Chinese expert consensus on ETS optimization and surgical quality control of day surgery for palmar hyperhidrosis". It aims to provide a reference for the clinical diagnosis and treatment of palmar hyperhidrosis for thoracic surgery colleagues in our country, to enhance their management level and work efficiency, and ultimately to achieve standardized quality control.

Objective:This study aims to investigate the differences in hemostatic efficacy and patient comfort between an innovative domestically produced biodegradable nasal packing sponge and a traditional absorbent sponge following endoscopic nasal surgery. Methods:A prospective, randomized controlled trial design was utilized, including 30 patients who were divided into two groups according to random allocation, each receiving one of the two types of nasal packing. The study assessed the hemostatic efficacy, comfort, and safety of the materials by comparing the rates of no bleeding within 24 hours after packing, re-bleeding rates after 48 hours, pain ratings in the head and nasal areas, scores on a visual analog scale for nasal ocular symptoms, and safety indicators between the two groups. Results:The rates of no bleeding within 24 hours post-packing were 73.33% for both the experimental and control groups, with a no-bleeding rate of 100% after 48 hours in both groups. The pain rating in the head and nasal areas at various times post-packing was Grade Ⅰ（100%） in both groups, with no statistically significant difference（P=1.000）. The experimental groups sneezing score on the day of packing was（0.73±1.03）, lower than the control groups（2.27±1.67）, （P=0.007）; after 48 hours, the experimental groups sneezing score was（0.67±0.98）, also lower than the control groups（1.67±1.18）, （P=0.019）. There was no significant difference between the two groups in the Lund-Kennedy scoring during endoscopic examinations at the screening period, 7 days, 1 month, and 3 months post-packing（P>0.05）. Laboratory tests for other examination indicators were normal in both groups. Conclusion:The innovative domestically produced biodegradable nasal packing sponge not only provides hemostatic efficacy comparable to imported materials but also significantly improves patient comfort after surgery. It represents an economical and effective choice for nasal packing materials.

Head and neck tumors are one of the major diseases that threaten human health. Targeted chemotherapy is an important treatment for head and neck tumors. However, many anti-cancer drugs are difficult to reach effective concentrations in tumors and can cause damage to normal tissues. Therefore, the efficient delivery of anti-tumor drugs, improvement of their therapeutic effects, and reduction of their adverse effects on the whole body and locally are urgent issues in targeted drug research. Liposomes have been widely studied due to their unique characteristics, including amphiphilicity, biocompatibility, biodegradability, and low toxicity. This article outlines the current applications and prospects of liposome drug delivery systems in different treatment modalities for head and neck tumors in recent years, aiming to provide more options for the treatment of head and neck tumors.

Cationic carriers have demonstrated broad application prospects in drug delivery due to their excellent drug-loading capacity and delivery performance. However, their high-density positive surface charge often leads to systemic toxicity and nonspecific uptake, posing significant barriers to clinical translation. In recent years, the emergence of charge shielding and stimuli-responsive strategies has provided effective avenues for modulating biocompatibility and targeting specificity. This review systematically summarizes the applications of chemical modification, natural polymer coating, and biomimetic membrane strategies in charge shielding. Furthermore, it explores the roles of endogenous stimuli such as pH, enzymes, and reactive oxygen species, as well as exogenous triggers like light and ultrasound, in achieving precise activation and controlled release. With the integration of multi-functional modules and the development of intelligent delivery platforms, cationic carriers are progressively advancing from laboratory research toward clinical translation. This review also discusses the translational potential and critical technical bottlenecks of related delivery systems, aiming to provide a theoretical framework and some reference for the design of next-generation smart delivery systems.

Objective To introduce a modified technique of right ventricular outflow tract (RVOT) reconstruction using a handmade bicuspid pulmonary valve crafted from expanded polytetrafluoroethylene (ePTFE) and to summarize the early single-center experience. Methods Patients with complex congenital heart diseases (CHD) who underwent RVOT reconstruction with a handmade ePTFE bicuspid pulmonary valve due to pulmonary regurgitation at Guangdong Provincial People’s Hospital from April 2021 to February 2022 were selected. Postoperative artificial valve function and right heart function indicators were evaluated. Results A total of 17 patients were included, comprising 10 males and 7 females, with a mean age of (18.18±12.14) years and a mean body weight of (40.94±19.45) kg. Sixteen patients underwent reconstruction with a handmade valved conduit, with conduit sizes ranging from 18 to 24 mm. No patients required mechanical circulatory support, and no in-hospital deaths occurred. During a mean follow-up period of 12.89 months, only one patient developed valve dysfunction, and no related complications or adverse events were observed. The degree of pulmonary regurgitation was significantly improved post-RVOT reconstruction and during follow-up compared to preoperative levels (P<0.001). Postoperative right atrial diameter, right ventricular diameter, and tricuspid regurgitation area were all significantly reduced compared to preoperative values (P<0.05). Conclusion The use of a 0.1 mm ePTFE handmade bicuspid pulmonary valve for RVOT reconstruction in complex CHD is a feasible, effective, and safe technique.
