The theory of constitution in traditional Chinese medicine （TCM） has emerged as a new discipline in recent years. Constitution plays a vital role in the onset，progression，transformation，and prognosis of diseases. At present，some clinical scholars have adopted a novel diagnostic and treatment model of "constitution differentiation-disease identification-syndrome differentiation"，in which constitution is regarded as a core element throughout the diagnostic and therapeutic process. Constitution is closely associated with etiology，onset，pathogenesis，syndrome differentiation，and treatment. Against this background，the construction of animal models based on constitution holds far-reaching significance for advancing clinical research. This paper focuses on the construction and evaluation of rodent models with Qi-deficiency constitution，aiming to explore how to further induce Qi-deficiency syndromes and related disease states on the basis of Qi-deficiency constitution models，thereby developing an integrated animal model that embodies the trinity of "constitution-disease-syndrome". The establishment of this model not only provides a solid experimental foundation for the development of new therapies and drugs in TCM targeting specific constitutions，diseases，and syndromes，but also greatly promotes the modernization and scientific advancement of TCM theory. By comprehensively applying multidisciplinary technologies and methods，the study evaluates the model's validity，reliability，and practicality，with the aim of opening new avenues for future research in TCM and promoting the development of the field.

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.

ObjectiveTo investigate the mechanisms by which Jianpi Yangzheng Xiaozheng prescription （JPYZXZ） treats poorly cohesive gastric carcinoma （PC-GC） through regulation of ubiquitin-specific peptidase 51 （USP51）. MethodsIn vitro experiments： Cell viability and proliferation of PC-GC cell lines （MKN-45 and HGC-27） treated with different concentrations of JPYZXZ （2， 4， 6 g·L^-1） were assessed using Cell Counting Kit-8 （CCK-8） and colony formation assays. Cell migration was evaluated by wound healing （scratch） and Transwell assays. The mRNA and protein expression levels of USP51， zinc finger E-box-binding homeobox 1 （ZEB1）， and epithelial-mesenchymal transition （EMT）-related markers （e.g.， E-cadherin） were detected by quantitative real-time PCR （Real-time PCR） and Western blot， respectively. Subsequently， stable MKN-45 and HGC-27 cell lines with USP51 knockdown （sh-USP51） and overexpression （oe-USP51） were constructed. Their migration ability and EMT-related protein expression were further evaluated by scratch assay， Transwell assay， and Western blot. In vivo experiments： A subcutaneous xenograft model of MKN-45 human gastric cancer was established in BALB/c nude mice. Thirty mice were randomly divided into six groups （NC， NC + JPYZXZ， sh-USP51， sh-USP51 + JPYZXZ， oe-USP51， and oe-USP51 + JPYZXZ）， with five mice in each group. After successful modeling， mice in the treatment groups were administered JPYZXZ （30 g·kg^-1） by gavage for 28 days. Body weight and tumor volume were monitored during the experiment. The expression levels of USP51 and EMT-related proteins in tumor tissues were detected by Western blot and immunohistochemistry （IHC）. ResultsCompared with the blank group， the colony formation rate， wound healing rate， and number of migrated cells in MKN-45 and HGC-27 cells were significantly reduced in all JPYZXZ groups and the 5-fluorouracil （5-FU） group （P<0.05）. The mRNA and protein expression levels of USP51 were decreased （P<0.05）. The expression of ZEB1 and mesenchymal phenotype proteins （e.g.， N-cadherin and vimentin） was reduced （P<0.05）， whereas the expression of the epithelial marker E-cadherin was increased （P<0.05）. Compared with the control group， USP51 expression was decreased in the sh-USP51 group and increased in the oe-USP51 group （P<0.05）. Compared with the NC group， USP51 knockdown significantly reduced the migration and proliferation of gastric cancer cells （P<0.01）， decreased the expression of ZEB1 and EMT-related proteins， and increased E-cadherin expression （P<0.05）. In vivo results showed that JPYZXZ significantly inhibited the growth of xenograft tumors in nude mice （P<0.05） and markedly reversed the abnormal expression of EMT-related proteins in tumor tissues （P<0.05）. ConclusionThe therapeutic mechanisms of JPYZXZ in PC-GC may be associated with inhibition of the EMT process via regulation of the USP51-ZEB1 signaling pathway.

Objective: To investigate the influence of sinus morphology on the safety of hydraulic sinus floor elevation surgery and provide a biomechanical basis for clinical treatment. Methods: After approval by the Medical Ethics Committee of the institution, cone beam computed tomography imaging data from nine patients were collected. The sinus morphologies were classified into slope, flat and concave types. Three-dimensional finite element models of maxillary sinuses with the aforementioned morphologies were constructed using Mimics, Geomagic, Solidworks, and ANSYS software, followed by a simulation of the hydraulic elevation process. The sinus membrane elevation height was set at 1-6 mm. The pressure required for elevation and the equivalent, compressive, tensile, and shear stresses generated on the sinus membrane were recorded and analyzed. The equivalent stress distribution on the sinus membrane was visualized using contour plots. Results: The elevation pressure and the equivalent, compressive, tensile, and shear stresses generated on the sinus membrane increased along with the elevation height. When the sinus membrane was lifted to 6 mm, the elevation pressure was (301.17 ± 98.1) kPa, (151.85 ± 3.7) kPa, and (149.36 ± 10.31) kPa in the slope, flat and concave finite element analysis models, respectively. The equivalent stress was (1 023.86 ± 201.99) kPa in the slope sinuses, comparing with (687.91 ± 69.08) kPa and (698.27 ± 96.09) kPa in the flat and concave sinuses. Higher elevation pressure and the equivalent stress, compressive stress and shear stress values were found in the slope sinus than in the flat and concave sinuses under the same elevation height (P < 0.05). Stress distribution analysis revealed that stress was uniformly distributed in the flat sinuses, followed by concave sinuses, but asymmetrically distributed in the slope sinuses Conclusions The slope sinuses demonstrated inferior safety and efficiency compared with the flat and concave sinuses when performing hydraulic sinus floor elevation surgery.

To address the growing challenge of an increasing number of elderly lung cancer patients amidst China's aging population and to fill the gap in quality control standards for surgical treatment in this special population, this study aimed to develop a standardized surgical evaluation system for elderly lung cancer patients tailored to China's national conditions. The system was established through a literature review, integrated the pathophysiological characteristics of elderly patients, and was constructed following review, feedback, and revision by experts from multiple thoracic surgery centers. Employing a 100-point scoring system, it comprises three primary domains: physical infrastructure and geriatric adaptability foundational conditions (10 points); management level and perioperative care models (20 points); and technical proficiency and clinical outcomes (70 points). The system places a strong emphasis on geriatric adaptability, proposing specific, quantifiable indicators for age-friendly facility modifications, control of elderly-specific complications, multidisciplinary collaboration, and standardized perioperative management. It provides a convenient and measurable assessment tool for quality control in the surgical treatment of elderly lung cancer in China, which is expected to promote the standardization and homogenization of diagnosis and treatment.

Objective This study reports on the obligatory parasitism of water mites Arrenurus sp. on Anopheles messeae at the Manzhouli Port, Inner Mongolia, China. Methods Duing July 2024, a survey on the mosquito diversity was conducted at the Manzhouli Port. Captured mosquitoes and their ectoparasites were identified to species level. Results A total of 1840 adult mosquitoes were collected, representing species from three genera: Culex(Cx. modestus, Cx. pipiens pallens), Aedes(Ae. dorsalis, Ae. flavidorsalis, Ae. flavescens), and Anopheles (An. messeae). Among all the mosqutioes specimens,3 out of 150 captured An. messeae were found to carry ectoparasitic mites, with number of 2,4,27 mites separately. Morphological and molecular identification reached the same result as water mites(Hydrachnidiae, Hydracrina). COI gene sequence showed 94% similarity with the closest species Arrenurus truncatellus. Conlusions Literature review suggests water mites are host-specific parasitism of mosquito species and herein with the first record of Arrenurus sp. parasiting on An. Messeae in the most high-latitude region globally.

Owing to its inherent advantages—such as being non-destructive, rapid, highly molecule-specific, and minimally interfered with by moisture—Raman spectroscopy has been widely adopted in the fields of skin barrier function assessment, monitoring the transdermal penetration of active cosmetic ingredients, and the identification and quality control of cosmetic products. Despite these strengths, the practical application of this technique faces a significant bottleneck: the strong fluorescence background generated by endogenous skin components and exogenous cosmetic additives. Endogenous skin substances, such as structural proteins (e.g., collagen and elastin), metabolic coenzymes (e.g., nicotinamide adenine dinucleotide), and pigments (e.g., melanin), together with exogenous cosmetic constituents like organic colorants, chemical sunscreens, and fragrances, often possess strong absorption and emission characteristics. When excited by lasers, these components produce a fluorescence background that can be 10⁶ to 10⁸ times stronger than the Raman scattering signals, effectively masking the inherently weak vibrational fingerprint information. In recent years, driven by the rapid development of optoelectronic hardware and artificial intelligence algorithms, fluorescence suppression strategies have evolved from isolated, single-method approaches into comprehensive, multi-level synergistic systems. These systems are categorized into three distinct tiers: sample preparation, signal acquisition, and data processing. At the sample preparation level, techniques such as photobleaching and surface-enhanced Raman spectroscopy (SERS) are employed to eliminate or bypass the generation of fluorescence at the source. At the signal acquisition level, instrumental improvements—including the use of long-wavelength near-infrared excitation (typically 785 nm or 1 064 nm), confocal spatial filtering, and shifted excitation Raman difference spectroscopy (SERDS)— are utilized to physically isolate Raman signals from the fluorescence background. Furthermore, at the data processing level, numerical baseline correction methods such as polynomial fitting, penalized least squares (e.g., airPLS, arPLS), wavelet transform, and derivative algorithms are increasingly integrated into the analytical pipeline to extract Raman spectral features from mixed signals without increasing hardware costs or acquisition time. This review provides a systematic categorization and critical evaluation of these fluorescence suppression methods, detailing their underlying principles, technical advantages, and inherent limitations in diverse experimental setups. By focusing on critical application scenarios—including skin barrier assessment, percutaneous absorption monitoring, the routine quality control of cosmetics, and the emerging field of portable on-site detection—this paper explores the current state of technique selection and optimization. Finally, the article discusses future development trends, emphasizing the necessity of constructing adaptive, tiered suppression strategies, developing intelligent and automated data processing algorithms, and promoting the integration of portable, multi-modal diagnostic devices. The objective of this review is to provide a comprehensive technical reference to facilitate the transition of Raman spectroscopy from a specialized laboratory tool into a routine, robust analytical platform for advancements in skin science and cosmetic research.

Objective The present study aimed to evaluate the clinical efficacy of hydraulic sinus floor elevation for the treatment of insufficient bone height in the posterior maxilla through a systematic review and Meta-analysis, so as to provide evidence for clinical practice. Methods Databases including PubMed, Embase, Cochrane Library, and Clinical Trials.gov were searched up to May 2025. Randomized controlled trials, non-randomized controlled trials, cohort studies, cross-sectional studies, and case-control studies that involved patients receiving hydraulic sinus floor elevation with simultaneous or delayed implant placement were included. Exclusion criteria comprised in vitro studies, animal experiments, narrative reviews, unpublished data, commentaries or expert opinions, studies with unclear sample sizes, and publications without full-text access or unavailable outcome data. Three investigators independently performed literature screening and quality assessment. A single-arm Meta-analysis was conducted using Stata 18.0 for studies meeting the inclusion criteria. The outcome measures were the incidence of sinus membrane perforation, implant survival rate, and endo-sinus bone gain. The Cochrane Risk of Bias 2 (RoB2) tool and the Joanna Briggs Institute (JBI) critical appraisal checklist were used to assess the methodological quality of randomized controlled trials and non-randomized controlled trials, respectively. The overall certainty of evidence was assessed using the GRADE（Grading of Recommendations Assessment, Development and Evaluation）system. Results Nineteen studies with 982 patients, 1 151 elevated sites, and 1 263 implants were finally included. The Meta-analysis showed that the intraoperative sinus membrane perforation rate of hydraulic sinus floor elevation was 2.0% [ES = 0.02, 95% CI (0.00, 0.04)] (18 studies, 1 061 sites); the implant survival rate was 99.0% [ES = 0.99, 95% CI (0.97, 1.00)] (17 studies, 1 253 implants); and the mean vertical bone gain was 7.80 mm. For this outcome, heterogeneity among studies was extremely high (I2 = 98.6%), thus only descriptive analysis was performed. Egger's test revealed no significant publication bias for the three outcomes. GRADE grading indicated very low certainty of evidence for mucosal perforation, implant survival rate, and endo sinus bone gain. Conclusion Current preliminary evidence suggests that hydraulic sinus lift may be a safe minimally invasive technique, but the evidence is very low, and more high quality, long term follow up randomized controlled clinical trials are still needed for further verification.

BACKGROUND: T-cell lymphoblastic lymphoma/acute lymphoblastic leukemia (T-LBL/ALL) is an aggressive form of hematological malignancy associated with poor prognosis in adult patients. Histone deacetylases (HDACs) are aberrantly expressed in T-LBL/ALL and are considered potential therapeutic targets. Here, we investigated the antitumor effect of a novel HDAC inhibitor, chidamide, on T-LBL/ALL. METHODS: HDAC1, HDAC2 and HDAC3 levels in T-LBL/ALL cell lines and patient samples were compared with those in normal controls. Flow cytometry, transmission electron microscopy, and lactate dehydrogenase release assays were conducted in Jurkat and MOLT-4 cells to assess apoptosis and pyroptosis. A specific forkhead box O1 (FOXO1) inhibitor was used to rescue pyroptosis and upregulated gasdermin E (GSDME) expression caused by chidamide treatment. The role of the FOXO1 transcription factor was evaluated by dual-luciferase reporter and chromatin immunoprecipitation assays. The efficacy of chidamide in vivo was evaluated in a xenograft mouse. RESULTS: The expression of HDAC1, HDAC2 and HDAC3 was significantly upregulated in T-LBL/ALL. Cell viability was obviously inhibited after chidamide treatment. Pyroptosis, characterized by cell swelling, pore formation on the plasma membrane and lactate dehydrogenase leakage, was identified as a new mechanism of chidamide treatment. Chidamide triggered pyroptosis through caspase 3 activation and GSDME transcriptional upregulation. Chromatin immunoprecipitation assays confirmed that chidamide led to the increased transcription of GSDME through a more relaxed chromatin structure at the promoter and the upregulation of FOXO1 expression. Moreover, we identified the therapeutic effect of chidamide in vivo . CONCLUSIONS This study suggested that chidamide exerts an antitumor effect on T-LBL/ALL and promotes a more inflammatory form of cell death via the FOXO1/GSDME axis, which provides a novel choice of targeted therapy for patients with T-LBL/ALL.
