OBJECTIVE To explore the improvement effects of Suting pingchuan decoction （STPC） on bronchial asthma in rats and its potential mechanism. METHODS Male SD rats were randomly divided into blank group， model group， STPC low-， medium- and high-dose groups （4.14， 8.28， and 16.56 g/kg， respectively， based on the crude drug dosage）， and dexamethasone group （positive control， 1 mg/kg）， with 8 rats in each group. Except for the blank group， the other groups were sensitized by intraperitoneal injection of ovalbumin and challenged by nebulized inhalation of ovalbumin to establish a bronchial asthma model. From the day of nebulization challenge， rats of each group were administered the corresponding drug solution or normal saline by gavage 1 hour before aerosolization， once a day， for 7 consecutive days. During the experiment， behavioral changes in rats of each group were observed. After the last administration， the levels of inflammatory factors （interleukin-1β， interleukin-18） in bronchoalveolar lavage fluid （BALF）， and oxidative stress indexes [malondialdehyde （MDA）， superoxide dismutase （SOD）] in lung tissue were determined； pathological changes in lung tissue were observed； cell apoptosis in lung tissue， and the mRNA expression of nucleotide-binding domain leucine-rich repeat and pyrin domain-containing receptor 3 （NLRP3） and the protein expressions of NLRP3， cleaved caspase-1， caspase-1， gasdermin D （GSDMD） and gasdermin D-N-terminal domain （GSDMD-N） in lung tissue were detected. RESULTS Compared with the blank group， rats in the model group showed symptoms such as scratching their ears and noses and frequent sneezing； the lung tissue structure was severely damaged， and there was obvious inflammatory cell infiltration. The levels of inflammatory factors in BALF， as well as the level of MDA， TUNEL-apoptotic cell rate， the mRNA expression of NLRP3， and the protein expressions of NLRP3， cleaved caspase-1， caspase-1， GSDMD-N and GSDMD in lung tissue were significantly increased or up-regulated， while the level of SOD in lung tissue was significantly decreased （ P ＜0.05 or P ＜0.01）. Compared with the model group， the above symptoms and pathological damages of lung tissue in each drug group were significantly improved， and all quantitative indicators （except for the protein expressions of GSDMD in the STPC groups， as well as the level of SOD， and the protein expressions of cleaved caspase-1， caspase-1 and GSDMD-N in the STPC low-dose group） were significantly reversed （ P ＜0.05 or P ＜0.01）. CONCLUSIONS STPC can improve airway inflammation and lung tissue damage in rats with bronchial asthma， reduce the level of oxidative stress， and decrease the release of inflammatory factors such as IL-1β and IL-18. Its mechanism of action may be related to the inhibition of pyroptosis activation mediated by the NLRP3/caspase-1/GSDMD signaling pathway.

In recent years, there has been a significant surge in the prevalence of myopia at younger ages in China. Numerous studies have investigated methods for preventing and controlling myopia, including orthokeratology, low-concentration atropine eye drops, light therapy, posterior scleral reinforcement, and traditional Chinese medicine. These approaches can modulate choroidal thickness, blood flow, and target various molecular mechanisms. Orthokeratology and low-concentration atropine demonstrate a thickening effect on the choroid and regulate choroidal blood flow; the use of multi-point defocus control lenses also shows promise in thickening the choroid; the influence of light and light feeding therapy on myopia prevention and control is also reflected in the choroidal thickness and blood flow; and the traditional Chinese medicine has shown good prospect in influencing the microstructure of the choroid for myopia prevention and control. However, the long-term effects of various prevention and control measures on the choroid still need to be explored with a large sample size. This article provides an overview of various methods used to regulate the choroid and prevent myopia. The mechanisms by which these interventions act on the choroid are described to provide new insights and identity novel clinical strategies for myopia management.

Periodontitis is a globally prevalent inflammatory oral disease, affecting approximately 50% of the population worldwide and imposing a substantial burden on patients′ health and quality of life. Early and accurate diagnosis is critical for preventing disease progression; however, conventional diagnostic approaches often rely on subjective clinical assessments, which only primarily evaluate the cumulative state of the disease, thus limiting their ability to achieve precise early detection. In recent years, the rapid advancement of artificial intelligence (AI) in medical diagnostics has demonstrated significant promise, particularly through the integration of multimodal data to enable more comprehensive information capture and analysis. Multimodal data fusion, which combines diverse inputs such as imaging, clinical parameters, and biomarkers, offers transformative potential for AI-powered periodontitis diagnostics. This innovative approach aims to overcome the limitations of traditional methods, significantly enhancing diagnostic accuracy and predictive capabilities. This manuscript reviews the primary diagnostic techniques for periodontitis, explores recent advances in AI applications within this domain, and emphasizes the potential of multimodal data in facilitating precision diagnosis. Furthermore, it provides new insights and supports for personalized treatment strategies.

This article reviews the progress of clinical research on abnormal sounds after ceramic-on-ceramic total hip arthroplasty, with a focus on analyzing the differences between the third-generation and fourth-generation ceramic prostheses. Abnormal sounds generally refer to high-pitched audible sounds (such as creaking, clicking, etc.) during hip joint movement after surgery, which are considered possible precursors to prosthesis fragmentation (for example, patients with abnormal sounds have more ceramic particles in the joint fluid, and some are accompanied by prosthesis fragmentation). The fundamental frequency of abnormal sounds in the third-generation ceramic prostheses ranges from 400 to 7 500 Hz (approximately 1 500 Hz in males and 2 500 Hz in females), while the acoustic characteristics of the fourth-generation ones remain unclear. The reported occurrence time of abnormal sounds varies significantly among different studies, with an average of 6.4 to 40 months after surgery. This variation may be influenced by patient characteristics, surgical technique, and prosthesis type. Abnormal sounds are considered a possible early indicator of prosthesis fragmentation; for instance, higher concentrations of ceramic particles have been detected in the synovial fluid of affected patients, and some cases have been accompanied by prosthesis fracture. The incidence of abnormal sounds with the fourth-generation prostheses ranges from 3.8% to 46.6% (with a follow-up period exceeding 10 years), while the third-generation shows rates of 0% to 19.7% with no difference between the two generations. Although the fourth-generation prostheses are superior to the third-generation in material toughness (flexural strength>1 380 MPa) and hardness, they still fail to solve the problem of abnormal sounds, and the incidence may increase with the extension of the follow-up time (for example, in some studies, the incidence at 10-year follow-up is higher than that at 5-year follow-up). Abnormal sounds are mostly associated with movements such as extreme flexion (e.g., squatting) and walking. Different sound properties (such as friction sound) correspond to specific inducing movements and locations, among which friction sound requires vigilance against the risk of prosthesis fragmentation. The risk factors include patient-related factors (height, weight, activity level, etc.), surgical factors (prosthesis position angle), and prosthesis-related factors (design, diameter, neck length, etc.). Proposed mechanisms include abnormal edge loading, stripe wear, femoral neck impingement, wear particle generation, and prosthesis mismatch. Adverse outcomes include decreased patient satisfaction with life, revision surgery (with an incidence of 0.2% to 4.65%), and prosthesis fragmentation. Currently, there are still controversies in research. Future studies need to focus on special patient groups, surgical techniques (such as robot-assisted surgery), and the optimization of prosthesis materials and designs (such as gradient structures and surface coatings) to reduce the incidence of abnormal sounds.

Objective:To analyze the genetic characteristics of varicella-zoster virus（VZV）in Anhui province from 2022 to 2023.Methods:Vesicle fluid and throat swab samples were collected from suspected varicella patients in Anhui province during 2022—2023. Fresh vesicle fluid samples were selected for VZV isolation，and real-time PCR was used for VZV nucleic acid detection. For positive samples，the region containing five single nucleotide polymorphism（SNP）sites in the open reading frame 22（ORF22）fragment was amplified，and PCR products were sequenced to identify viral genotypes. Reference sequences of VZV genotypes were downloaded from GenBank，sequence alignment and phylogenetic tree analysis were performed using Sequencher and MEGA5.0 software. Additionally，four SNP sites in ORF38 and ORF62 fragments were detected to distinguish vaccine strains from wild strains.Results:Among 96 samples from suspected varicella cases，55 of 61 vesicle fluid samples and 21 of 35 throat swab samples were positive for VZV nucleic acid. The virus isolation rate for vesicle fluid samples was 14.75%. Genetic sequencing was successful for 51 strains，all of which were wild strains belonging to the clade 2 genetic branch. Compared with the reference strain of clade 2，the nucleotide and amino acid homologies of the ORF22 fragment were 99.46%~100% and 98.39%~100%，respectively. One strain（2023VZVCZ45）exhibited an A→G mutation at site 37916.Conclusion:The prevalent VZV strains detected in Anhui province during 2022—2023 were all wild strains of clade 2，with no vaccine-associated cases identified.

Turning to critical illness is a common stage of various diseases and injuries before death. Patients usually have complex health conditions, while the treatment process involves a wide range of content, along with high requirements for doctor′s professionalism and multi-specialty teamwork, as well as a great demand for time-sensitive treatments. However, this is not matched with critical care professionals and the current state of medical care in China. Telemedicine, which shortens the distance of medical professionals and the gap of disease diagnosis and treatments in various regions through electronic information, can effectively solve the current problem. Therefore, there is an urgent need to develop a standardized, high-quality visualization telemedicine round system .Therefore, experts have been organized to search domestic and foreign literature on telemedicine round for critically ill patients and to form this consensus based on clinical experiences so as to further improve the level of critical care treatments in regions.

Oral squamous cell carcinoma(OSCC)is a malignant lesion originating from the oral mucosal squamous epithelium,account-ing for over 80％of oral and maxillofacial malignancies.Key etiological factors include tobacco,alcohol abuse,and betel quid chewing.In China,its incidence has shown an overall upward trend,posing a significant threat to public health.OSCC exhibits high local invasive-ness,making early diagnosis critical for improving prognosis.Its clinical management requires close multidisciplinary collaboration among oral and maxillofacial surgery,head and neck surgery,radiation oncology,medical oncology,reconstructive surgery,radiology,patholo-gy,and nutritional support teams.Given the increasing disease burden of OSCC and rapid development of multidisciplinary collaborative models,an expert panel has formulated this integrated management consensus based on evidence-based medicine and extensive deliber-ation.Centered on the'Prevention-Screening-Diagnosis-Treatment-Rehabilitation'framework,the consensus provides comprehensive guidance for the entire disease course of OSCC patients,aiming to standardize clinical practice.

Background: Active surveillance (AS) has emerged as a viable management strategy for low-risk papillary thyroid microcarcinoma (PTMC), following pioneering trials at Kuma Hospital and the Cancer Institute Hospital in Japan. Numerous prospective cohort studies have since validated AS as a management option for low-risk PTMC, leading to its inclusion in thyroid cancer guidelines across various countries. From 2016 to 2020, the Multicenter Prospective Cohort Study of Active Surveillance on Papillary Thyroid Microcarcinoma (MAeSTro) enrolled 1,177 patients, providing comprehensive data on PTMC progression, sonographic predictors of progression, quality of life, surgical outcomes, and cost-effectiveness when comparing AS to immediate surgery. The second phase of MAeSTro (MAeSTro-EXP) expands AS to low-risk papillary thyroid carcinoma (PTC) tumors larger than 1 cm, driven by the hypothesis that overall risk assessment outweighs absolute tumor size in surgical decision-making. Methods: This protocol aims to address whether limiting AS to tumors smaller than 1 cm may result in unnecessary surgeries for low-risk PTCs detected during their rapid initial growth phase. By expanding the AS criteria to include tumors up to 1.5 cm, while simultaneously refining and standardizing the criteria for risk assessment and disease progression, we aim to minimize overtreatment and maintain rigorous monitoring to improve patient outcomes. Conclusion This study will contribute to optimizing AS guidelines and enhance our understanding of the natural course and appropriate management of low-risk PTCs. Additionally, MAeSTro-EXP involves a multinational collaboration between South Korea and Australia. This cross-country study aims to identify cultural and racial differences in the management of low-risk PTC, thereby enriching the global understanding of AS practices and their applicability across diverse populations.
