Objective To systematically analyze the characteristics of the disease burden of hypertensive heart disease (HHD) in the elderly (≥60 years) globally and in China from 1990 to 2021, and to predict its future trends from 2022 to 2040, with the aim of providing data support for optimizing comprehensive prevention and control strategies for HHD. Methods Based on the Global Burden of Disease (GBD) 2021 database, the number of prevalent cases and disability-adjusted life years (DALYs) of HHD in the elderly were extracted for the world, China, and five regions categorized by sociodemographic index (SDI). Joinpoint regression was used to analyze the temporal trends of age-standardized prevalence rate and age-standardized DALYs rate of HHD in the elderly. A three-factor decomposition method was applied to evaluate the relative contributions of aging, population growth, and epidemiological changes to the variations in the elderly HHD burden. Additionally, a Bayesian age-period-cohort model was used to predict the elderly HHD burden from 2022 to 2040. Results In 2021, the number of prevalent elderly HHD cases reached 10 283 000 globally and 3 412 400 in China, representing increases of 179.20% and 159.20% respectively, compared with 1990. The DALYs of elderly HHD were 18 812 700 person-years globally and 4 731 400 person-years in China, rising by 76.08% and 29.45% respectively from 1990. Meanwhile, the growth rates of the number of prevalent cases and DALYs of elderly HHD varied across different SDI regions. From 1990 to 2021, the age-standardized prevalence rate of elderly HHD in China, as well as the age-standardized DALYs rate of elderly HHD both globally and in China, showed significant downward trends (all average annual percentage changes<0, all P<0.001). In 2021, the 70-74 years age group accounted for the highest proportion of prevalent cases and DALYs of elderly HHD, both globally and in China. Decomposition analysis revealed that population growth was the dominant factor driving the increase in the elderly HHD burden across all regions. The prediction model results indicated that the number of prevalent cases and DALYs of elderly HHD would continue to rise globally and in China from 2022 to 2040, with the growth rate of the elderly HHD burden in China between 2021 and 2040 expected to exceed the global average. Conclusion Over the past 32 years, although the age-standardized disease rates of elderly HHD have mainly shown a downward trend globally and in China, the absolute number of the disease burden has increased substantially. The projection model indicates a continued upward trajectory, with the growth rate in China higher than the global average. Therefore, there is an urgent need to implement precise prevention and control strategies to effectively mitigate the disease burden of elderly HHD.

Thyroid cancer is one of the most prevalent cancers in the world, accounting for the increased sensitivity of diagnostic assessments, the environment, and extensive imaging. While open thyroidectomy still forms the base surgical treatment of differentiated thyroid carcinoma (DTC), its visible scarring and postoperative morbidity have mandatorily propelled a longitudinal shift to minimally invasive techniques. Robotic thyroidectomy using the bilateral axillo-breast approach (BABA) is an emerging transformative technique that combines robotic precision and visualization with oncologic efficacy and superior cosmetic outcomes to enhance recovery. Molecular diagnostics such as next-generation sequencing (NGS) and microRNA classifiers have transformed preoperative planning. These tools aid in accurate risk stratification, enabling clinicians to determine the course of surgery and avoid overtreatment. Artificial intelligence (AI) enhances precision medicine by improving nodule classification, predicting surgical risks, providing intraoperative navigation guidance, and supporting postoperative histopathological evaluations. Despite these innovations, cost, accessibility, and ethical governance issues highlight persistent challenges. This review consolidates the current state of robotic-assisted surgery for thyroid cancer with molecular profiling and AI. It proposes future aims and strides toward precision surgery that is accessible worldwide.

In view of the characteristics of H5N6 subtype avian influenza virus(AIV)that it has both high pathogenicity and the risk of cross-species transmission,posing a serious threat to the poultry farming industry and public health security,in order to effectively prevent and control the spread of H5N6 avian influenza,a rapid,sensitive and specific detection technolo-gy was established in this study.The specific monoclonal antibodies against the neuraminidase N6 protein of avian influenza A virus subtype H5N6 were obtained through hybridoma and monoclonal antibody technology.These antibodies were coupled and labeled with carboxyl-functionalized fluorescent quantum dots,along with previously prepared specific antibodies against the hemagglutinin H5 protein.A rapid fluorescence immunochromatographic detection method for the H5N6 subtype of avian influ-enza virus was established according to the principle of double-antibody sandwich immunochromatography.This method a-chieved a detection sensitivity of 1 ng/mL for recombinant hemagglutinin H5 subtype protein and 0.1 ng/mL for recombinant neuraminidase N6 subtype protein.Moreover,the method exhibited no cross-reactivity with other influenza subtypes or patho-gens,such as Newcastle disease(ND),infectious bronchitis(IB),and infectious laryngotracheitis(ILT),thus demonstrating good specificity.The method effectively identified the highly pathogenic avian influenza virus H5 subtype and directly distin-guished the H5N6 subtype with good accuracy.The fluorescent quantum dot immunochromatographic typing detection method established herein met the sensitivity,specificity,and accuracy requirements for H5N6 subtype detection,and can be further used for rapid detection of the H5 and H5N6 subtypes of avian influenza virus.

OBJECTIVE: To evaluate the efficacy and safety of Shexiang Tongxin Dropping Pill (STDP) in treating stable angina patients with phlegm-heat and blood-stasis syndrome by exercise duration and metabolic equivalents. METHODS: This multicenter, randomized, double-blind, placebo-controlled clinical trial enrolled stable angina patients with phlegm-heat and blood-stasis syndrome from 22 hospitals. They were randomized 1:1 to STDP (35 mg/pill, 6 pills per day) or placebo for 56 days. The primary outcome was the exercise duration and metabolic equivalents (METs) assessed by the standard Bruce exercise treadmill test after 56 days of treatment. The secondary outcomes included the total angina symptom score, Chinese medicine (CM) symptom scores, Seattle Angina Questionnaire (SAQ) scores, changes in ST-T on electrocardiogram and adverse events (AEs). RESULTS: This trial enrolled 309 patients, including 155 and 154 in the STDP and placebo groups, respectively. STDP significantly prolonged exercise duration with an increase of 51.0 s, compared to a decrease of 12.0 s with placebo (change rate: -11.1% vs. 3.2%, P<0.01). The increase in METs was significantly greater in the STDP group than in the placebo group (change: -0.4 vs. 0.0, change rate: -5.0% vs. 0.0%, P<0.01). The improvement of total angina symptom scores (25.0% vs. 0.0%), CM symptom scores (38.7% vs. 11.8%), reduction of nitroglycerin consumption (100.0% vs. 11.3%), and all domains of SAQ, were significantly greater with STDP than placebo (all P<0.01). The changes in Q-T intervals at 28 and 56 days from baseline were similar between the two groups (both P>0.05). Twenty-five participants (16.3%) with STDP and 16 (10.5%) with placebo experienced AEs (P=0.131), with no serious AEs observed. CONCLUSION STDP could improve exercise tolerance in patients with stable angina and phlegm-heat and blood stasis syndrome, with a favorable safety profile. (Registration No. ChiCTR-IPR-15006020).

Objective:To evaluate the effect of an electronic balance aid in balance rehabilitation training for patients with acute peripheral vestibular injury by comparing the outcomes of medication-only treatment and medication combined with vestibular rehabilitation using an electronic balance aid.Methods:This was a randomized controlled trial. The study subjects included 98 patients (40 males and 58 females, aged 25-69 years) diagnosed with idiopathic sudden sensorineural hearing loss (ISSNHL) with vertigo or vestibular neuritis, who were treated in the Department of Otorhinolaryngology-Head and Neck Surgery of Tianjin First Central Hospital from November 2022 to November 2023. All patients were randomly divided into the experimental group and the control group at a 1∶1 ratio using the sealed envelope method. Control group (conventional drug treatment): Patients received medication treatment for 2 weeks, including betahistine mesilate tablets, vitamin B1 tablets, methylcobalamin tablets, ginkgo biloba tablets, diphenhydramine hydrochloride injection (within 3 days of onset), metoclopramide hydrochloride injection, and glucocorticoids. Experimental group (conventional drug treatment+device training): On the basis of the same medication treatment as the control group, patients received vestibular rehabilitation training using an electronic balance aid (20 minutes per session, once a day,≥5 days per week, for a total of 2 weeks). SPSS software was used to compare the total scores of the Dizziness Handicap Inventory (DHI), the total scores of the Sensory Organization Test (SOT), and sensory analysis indicators between the two groups before and after treatment.Results:After treatment, vertigo symptoms significantly improved in both groups. DHI: The total DHI score in the control group decreased from 77.9±1.8 before treatment to 20.2±2.3 after treatment ( P<0.001). In the experimental group, the total DHI score decreased from 73.5±2.1 before treatment to 8.6±0.9 after treatment ( P<0.001). The difference in total DHI scores between the two groups after treatment was statistically significant, with the experimental group showing a lower score ( t=-4.616, P<0.001). The improvement in DHI scores was also more pronounced in the experimental group compared to the control group ( t=2.004, P=0.048). SOT: The total SOT score in the control group increased from 52.90±0.95 before treatment to 73.3±1.1 after treatment ( P<0.001). In the experimental group, the total SOT score increased from 54.9±0.8 before treatment to 83.5±0.9 after treatment ( P<0.001). The difference in total SOT scores between the two groups after treatment was statistically significant, with the experimental group showing a higher score ( t=7.104, P<0.001). The improvement in SOT scores was also more pronounced in the experimental group compared to the control group ( t=6.532, P<0.001). Sensory Analysis Indicators Proprioception (SOM): In the experimental group, the proprioception score significantly increased after treatment compared with before treatment ( t=-2.338, P=0.029), while, there was no statistically significant difference in the proprioception score of the control group before and after treatment ( P=0.537). Before treatment, there were no statistically significant differences in visual, vestibular, or visual dependence scores between the two groups (all P>0.05). After treatment, the visual, vestibular, and visual dependence scores of both groups significantly increased compared with those before treatment (all P<0.05); moreover, the post-treatment visual, vestibular, and visual dependence scores of the experimental group were significantly higher than those of the control group (all P<0.05). Conclusion:Compared with medication-only treatment, the combination of an electronic balance aid and medication for the treatment and rehabilitation training of patients with acute peripheral vestibular injury can significantly improve the therapeutic effect in the short term.

Objective To investigate the efficacy of varying doses of methylprednisolone(MP)on mice with acute exacerbations of chronic obstructive pulmonary disease(AECOPD)induced with influenza A virus(IAV).Methods Mouse model of COPD was established using LPS combined with smoking for 12 weeks,and then these COPD mice were treated with administration of 40 μL IAV via nasal drip to establish a AECOPD model.A total of 15 AECOPD mice were randomly divided into low-,medium-and high-dose MP groups,oseltamivir group and blank group.The body weight and survival time were monitored within 10 d after IAV infection.On days 1,3,and 5 post-treatment,lung function was assessed using whole-body plethysmography(WBP),inflammatory factors in bronchoalveolar lavage fluid(BALF)were quantified with ELISA,viral titers in BALF were determined using plaque assays,and colony-forming units were evaluated with blood agar plates.Immunofluorescence analysis:① Pulmonary immunofluorescence assay:Mice were randomly categorized into(n=4):LPS 1-day group,LPS 3-day group,and LPS+MP treatment group.All groups received an initial dose of LPS via atomization;subsequently,the LPS+MP treatment group received a single gavage dose of MP.Lung tissues were harvested from the 1-day LPS group on 1 d post-treatment,and from the 3-day LPS and LPS+MP groups on 3 d for immunofluorescence staining.② Cellular immunofluorescence assay:Mouse bone marrow neutrophils were classified into blank control(no intervention),LPS stimulation(LPS group),MP intervention with LPS stimulation(LPS+MP group),and MP intervention alone(MP group).The above cells were collected in 4 h after corresponding interventions for subsequent cellular immunofluorescence analysis.Results ①The medium-dose MP group demonstrated the most significant improvement in survival rate,weight recovery,and lung function when compared to other groups(P＜0.05).② Treatment of medium-dose MP obviously reduced the levels of IL-6 and neutrophil extracellular traps(NETs)(P＜0.05),while,elevated inflammatory factors and NETs were observed in the high-dose MP group on day 5 post-treatment.③ Notable decline in the lung injury score was found in the medium-dose MP group than the other groups(P＜0.05).④The high-dose MP group exhibited substantial bacterial proliferation and delayed viral clearance since day 5 after treatment.Conclusion Medium-dose MP shows best efficacy in treatment of IAV-induced AECOPD,and the dose neither delays viral clearance nor increases the risk of bacterial infection following viral infection.

Osteoarthritis （OA） and stroke are common clinical diseases that reduce patients' quality of life and place a burden on families and society. Ruyi Zhenbaowan， a classic prescription in Tibetan medicine， have the functions of clearing heat， awakening the brain and opening orifices， relaxing tendons and promoting meridian circulation， and eliminating yellow water. Clinically， they are used to treat osteoarthritis， post-stroke sequelae， neuropathic pain， and other related conditions. Modern pharmacological studies have demonstrated their anti-inflammatory， analgesic， and nerve-repairing effects. However， current research remains insufficient regarding the appropriate indications， timing， and efficacy of this medicine in treating relevant diseases. To enhance clinicians' understanding of this medicine and promote its standardized and rational clinical use， a panel of national experts， including clinical specialists， Tibetan medicine practitioners， pharmacologists， and methodologists， formulated this consensus based on clinical experience and evidence-based practice. The Cochrane systematic review framework， the Grading of Recommendations Assessment， Development and Evaluation （GRADE） system， and the nominal group method were employed to generate seven graded recommendations and 19 consensus-based suggestions. These recommendations clearly define the key points in the clinical application of Ruyi Zhenbaowan， including therapeutic indications， dosage and administration， treatment duration， and medication safety. The consensus specifically addresses the clinical efficacy， appropriate timing of administration， dosage strategies， treatment cycles， and combination medication strategies for treating osteoarthritis and stroke and provides an overview of safety considerations. The aim is to provide standardized guidance for hospitals and healthcare institutions nationwide to ensure the rational application of Ruyi Zhenbaowan in the treatment of osteoarthritis and stroke， reduce medication-related risks， and further leverage its clinical advantages. This consensus has been approved and issued by the China Association of Chinese Medicine， with the standard number GS/CACM 369-2024.

Objective:To analyze the real-world practices of resecting sessile colorectal polyps of varying long diameters using cold forcep polypectomy (CFP), cold snare polypectomy (CSP), or endoscopic mucosal resection (EMR).Methods:A total of 12 290 nonpedunculated colorectal polyps of long diameter ≤19 mm (from 10 295 patients) were retrospectively enrolled from January 2022 to December 2023. Polypectomy was conducted by 30 endoscopists. The polyps were categorized into three groups based on long diameter: 1-5 mm, >5-10 mm and >10-19 mm, and the differences of polypectomy methods were compared in three groups. The usage of hemostatic clips in CSP among >5-10 mm polyps and the changes in resection methods between 2022 and 2023 were analyzed.Results:CFP (6 769 polyps, 81.7%) was the predominant method for resecting 1-5 mm sessile polyps (8 289 polyps). For sessile polyps sized >5-10 mm (2 455 polyps), CSP was used most (1 372, 55.9%), although its utilization varied significantly among physicians with the median usage rate of 52.9% (40.3%, 60.0%). EMR (1 349 poolyps, 87.3%) was the main method for >10-19 mm sessile polyps. The usage rate of CSP in sessile polypectomy for polyps >5-10 mm significantly increased from 45.7% (503/1 101) in 2022 to 64.2% (869/1 354) in 2023. The overall frequency of using clip in CSP for >5-10 mm sessile polyps was 40.1% (550/1 372), demonstrating notable variability among different endoscopists with median usage rate of 48.3% (29.8%, 67.9%).Conclusion:Varied resection methods are observed among endoscopists for sessile polyps measuring ≤19 mm. CFP is primarily utilized for polyps of 1-5 mm, while CSP is favored for polyps >5-10 mm, with an increasing annual usage rate. EMR is the main approach for the polyps >10-19 mm. Additionally, notable variations in the use of metal clips during CSP are observed among different physicians.
