This paper systematically reviewed the concept of authentication studies on traditional Chinese medicine （TCM） classics and the research achievements of scholars across historical and contemporary periods. We categorized the authentication studies on TCM classics into four types， including work-oriented authentication research， metho-dological studies on authentication， extended authentication research， and single-book authentication. Multiple methods were applied comprehensively， including investigating bibliographic documents of successive dynasties， analyzing the academic contents of medical books， studying the textual characteristics of medical books， examining the cited references in medical books， verifying the biographies of authors， and analyzing the interpolations and accretions in medical books， to distinguish the authenticity of TCM classics. The academic value of authenticity identification of TCM classics is concluded in three aspects，i.e. it serves as an important means to distinguish authenticity from falsehood in TCM classics， an important guarantee for inheriting the essence of TCM literature， and a key to unlocking the academic treasure trove of TCM classics and achieving inheritance-based innovation， which will lay a solid documentary foundation for constructing identification methodologies and standardized systems.

As a pivotal strategy to alleviate the shortage of organ donors, xenotransplantation has achieved remarkable advances in both pre-clinical and clinical studies in recent years, driven by continuous optimization of gene modification techniques and immunosuppressive regimens. Nevertheless, clinical translation still confronts formidable challenges, including rejection and heightened infection risks, which severely compromise long-term graft survival. Consequently, the role of immunosuppressive regimens in xenotransplantation has become increasingly prominent. This article summarizes the mechanisms underlying xenogeneic immune rejection, the latest developments in immunosuppressive regimens, cutting-edge strategies for inducing immune tolerance and the major hurdles facing clinical xenotransplantation. It delves into potential optimization strategies and directions for future clinical research, aiming to offer theoretical insights and practical guidance for the safe and effective application of clinical xenotransplantation.

Objective To investigate the efficacy and safety of EGFR-TKIs monotherapy and its combination therapy in the first-line treatment of advanced non-small cell lung cancer （NSCLC） patients with EGFR mutations. Methods Databases such as PubMed, Embase, Cochrane Library, and ClinicalTrials.gov were systematically searched to collect eligible phase Ⅱ/Ⅲ randomized controlled trials （RCTs）, with the time range from the establishment of the databases to June 2023. Two researchers independently screened the literature, extracted data, and assessed the risk of bias in the studies. Outcome data, including overall survival （OS）, progression-free survival （PFS）, objective response rate （ORR）, grade 3 or higher adverse events （≥3 AEs）, and serious adverse events （SAEs）, were collected. A network meta-analysis was performed using R software （version 4.2.1） under the Bayesian theoretical framework. Subgroup analyses of survival outcomes （OS, PFS） were conducted based on different clinical and pathophysiological characteristics of the patients. Results A total of twenty-eight phase Ⅱ/Ⅲ RCTs were included in the study, involving a total of 7 460 patients and 18 first-line treatment regimens. The results showed that in terms of efficacy, gefitinib + pemetrexed-containing chemotherapy performed best in OS and ORR, while osimertinib + bevacizumab performed best in PFS. In terms of safety, furmonertinib had the lowest incidence of ≥3 grade AEs, and osimertinib had the lowest incidence of SAEs. Subgroup analysis results indicated that the efficacy and safety of various treatment regimens differed among patients with different clinical and pathological characteristics. Conclusion Monotherapy with third-generation EGFR-TKIs, represented by osimertinib, serves as the preferred therapeutic option considering both efficacy and safety profiles. While some combination therapies could enhance survival benefits, need to be vigilant about increased toxicity. Clinical decision-making should be tailored based on patients’ mutation subtypes, comorbidities, and tolerance.

On the basis of reviewing the academic history of authentication of ancient traditional Chinese medicine （TCM） classics， this paper systematically expounds the theoretical foundations of bibliography in authentication. It discusses six specific approaches and their practical applications， including examining the bibliographic records in successive dynastic catalogues to verify the chronological sequence of transmission， comparing differences in bibliographic classification to discern authenticity， investigating author information to identify pseudepigraphic forgeries， comprehensively applying various bibliographies to identify the titles and editions of volumes and chapters， examining block-print dating information to detect fraudulent publication imprints， and verifying traces of collection and circulation to identify forged seals， colophons， and inscriptions. Finally， the paper explores the contemporary value and future directions of bibliographic authentication， which are of significant theoretical and practical importance for promoting the modern transformation of bibliographic authentication methodology and for advancing research on the authentication of ancient TCM texts.

Organ transplantation is an effective therapy for end-stage organ failure. Recipients require lifelong immunosuppressive therapy and regular monitoring, while conventional management models are limited by intermittence and passivity. Digital health technologies, including mobile health applications, wearable devices, telemedicine, artificial intelligence and big data analytics, can break the constraints of time and space, expand medical service coverage and realize real-time data collection and intelligent analysis, offering new prospects for full-cycle management of transplant recipients. This article systematically summarizes the development history of digital health technologies in the management of transplant recipients, and concludes the application evidence and existing challenges in medication adherence management, physiological indicator monitoring and remote follow-up among various transplant recipients, so as to provide references for establishing a more scientific and individualized digital management system for organ transplantation.

Xenogeneic kidney transplantation is an important approach to alleviate the shortage of donor kidneys, but acute rejection remains the main obstacle in its clinical application. Xenogeneic acute rejection shows a clear temporal sequence: in the early stage, it is mainly mediated by antibodies and occurs through humoral rejection, with pre-existing antibodies targeting α-Gal and non-Gal antigens, activating complement and inducing thrombotic microangiopathy; in the later stage, it gradually transforms into a cellular rejection driven by infiltration of T cells and macrophages. In terms of diagnosis, donor-derived cell-free DNA can serve as an early non-invasive warning indicator, and histopathological biopsy remains the gold standard. In 2024, the Banff Working Group on Transplant Pathology of xenogeneic kidney transplantation released the first consensus on the pathological assessment of pig-human kidney/heart xenogeneic transplantation. However, this is currently only a reporting framework, and an independent grading system still awaits more clinical data. The treatment mainly focuses on multi-gene-modified donors combined with intensified immunosuppression, but it still faces challenges such as immature immunization regimens, the absence of monitoring systems and prominent infection risks. This article reviews the mechanisms, diagnostic monitoring, treatment strategies and clinical dilemmas of acute rejection, providing a reference for subsequent research.

Objective:To evaluate the relationship between intraoperative mechanical power and postoperative pulmonary complications in patients undergoing long-duration neurosurgery.Methods:This was a case-control study. Based on the duration of mechanical ventilation>8 h, the clinical data(baseline characteristics, intraoperative information and hospitalization) of patients underwent first elective craniotomy under general anesthesia at Tianjin Huanhu Hospital from January 1, 2019 to December 31, 2021 were retrospectively collected. The patients were divided into pulmonary complication group (group P) and non-pulmonary complication group (group N) based on the occurrence of postoperative pulmonary complications. Ventilation-related risk factors for postoperative pulmonary complications were identified by the multivariate logistic regression analysis, and the accuracy of intraoperative tidal volume, peak airway pressure, respiratory rate and mechanical power in predicting postoperative pulmonary complications was assessed using the receiver operating characteristic curve.Results:A total of 555 patients were finally included, with 247 patients in group P and 308 patients in group N. The duration of mechanical ventilation, tidal volume, peak airway pressure, respiratory rate, mechanical power, length of hospitalization and mortality during hospitalization were significantly higher in group P than in group N ( P<0.05). The results of multivariate logistic regression analysis showed that intraoperative peak airway pressure, respiratory rate and mechanical power were risk factors for postoperative pulmonary complications ( P<0.05). The area under the receiver operating characteristic curve (95% confidence interval) of intraoperative peak airway pressure, respiratory rate and mechanical power in predicting postoperative pulmonary complications was 0.726(0.572-0.666), 0.619(0.684-0.768) and 0.958(0.942-0.974)respectively. Conclusions:Intraoperative mechanical power is an independent risk factor for postoperative pulmonary complications and an important ventilation parameter for predicting postoperative pulmonary complications in patients undergoing long-duration neurosurgery.

Objective To investigate the relationship between the expression of nuclear factor ⅠB(NFⅠB)in myeloid cells and intestinal inflammation by constructing NFⅠB conditional gene knockout(cKO)mice.Methods Human Protein Atlas database,Genotype-Tissue Expression database,and FANTOM5 database were used to investigate the expression of NFⅠB in inflammatory cells.NFⅠB-floxed mice were constructed using CRISPR/Cas9 technology and hybridized with LyZ2-Cre transgenic mice.Myeloid specific NFⅠB cKO mice(NFⅠBfl/flLyz2-Cre)were obtained by self-crossing the progeny.After the genotype identification of mice by agarose gel electrophoresis,4 NFⅠB cKO mice of C57BL/6N strain were selected as experimental group,and 4 non-cKO mice were selected as control group.Both groups were induced with 2.5％dextran sulfate sodium salt(DSS)under the same condition to establish a chronic colitis model,and the severity of colitis was evaluated by clinical manifestations and histopathology.Results Analysis showed that NFⅠB was expressed in both myeloid granulocytes and monocytes,and the highest expression was found in neutrophils.NFⅠB cKO mice were successfully constructed using CRISPR/Cas9 technology and Cre-loxP system.DSS-induced enteritis NFⅠB cKO mice developed diarrhea,gross blood stools,reduced activity,and weight loss in a short time.The gross examination of the intestines showed that the colon of the NFⅠB cKO mice was significantly shorter than that of the non-cKO mice([8.23±0.35]cm vs[10.30±0.36]cm,P＜0.01).Intestinal H-E staining showed changes in mucosal glandular structure and connective tissue hyperplasia with extensive inflammatory cell infiltration in NFⅠB cKO mice.The histological score of NFⅠB cKO mice was significantly higher than that of non-cKO mice(4.25±0.50 vs 0.50±0.58,P＜0.01).Intestinal immunohistochemical staining showed that more CD11b positive cells were recruited in NFⅠB cKO mice than non-cKO mice.Conclusion Myeloid specific NFⅠB cKO mice have been successfully constructed,and NFⅠB in myeloid cells can reduce infiltration of immune cells(granulocytes or/and monocytes)to inhibit intestinal inflammation.

Objective To investigate the alterations in skeletal muscle function and mass in an experimental mouse model of high-intensity exercise in a hot and humid environment.Methods Twenty-four male C57BL/6J mice(7～8 weeks old,weighing 21.30±0.67 g)were randomly assigned to a control group(CON group),a normal temperature and humidity exercise group(NE group),and a high temperature and humidity exercise group(HE group),with 8 mice in each group.The HE group was subjected to a high-temperature simulation chamber,maintaining a temperature of 37～39℃and humidity of 70%～80%,for a 60-minute exercise intervention at a 10° incline and 80%of maximum velocity(12 min of exercise followed by 8 min of rest,for 3 cycles).The CON group did not exercise,while the NE group exercised in the same manner in a normal temperature and humidity environment.The overall condition of the mice was evaluated by monitoring their body weight and analyzing their body composition.Their serum creatinine and urea levels were detected using an automated biochemical analyzer.After exercise,skeletal muscle function in the mice of each group was assessed by measuring their grip strength and exhaustion time.The skeletal muscle contractility and resistance to fatigue were evaluated using an in situ/in vivo/ex vivo muscle testing system.HE staining was employed to observe the morphological and structural changes in the skeletal muscles,and the average cross-sectional area and diameter of the muscle fibers were analyzed.Genes related to protein synthesis(Eif4ebp1,p70S6k)and breakdown(Foxo3,Fbxo32,Trim63)and heat stress-related genes(Hsf-1,Hspa1a,Hsp90aa)were quantified using RT-qPCR.Results ① Compared with the CON and NE groups,the HE group exhibited significant decreases in body weight(P<0.01)and lean body mass(P<0.05),an upward trend of creatinine level(P<0.05),and increases in the urea content(P<0.01).② The mice in the HE group had notably reduced grip strength(P<0.001),diminished skeletal muscle contraction,and weakened resistance to fatigue(P<0.05)than the CON and NE groups.③ The HE group demonstrated a reduction in the average cross-sectional area of muscle fibers(P<0.05)and a decrease in average fiber diameter(P<0.05),with particular up-regulation of Fbxo32,Trim63 and Eif4ebp1(P<0.01)and down-regulation of p70S6k(P<0.05)in comparison to the NE and CON groups.④ The expression levels of heat stress-related genes were higher in the HE group than the CON and NE groups(P<0.05).Conclusion High-intensity exercise in a hot and humid environment can lead to a decline in skeletal muscle function and mass in mice,potentially due to the disturbance of skeletal muscle protein synthesis and degradation triggered by excessive heat stress.
