Digital and intelligent technologies serve as the core engine driving the inheritance of the essence and the innovation while upholding the fundamentals of traditional Chinese medicine（TCM）. Currently， the digital and intelligent transformation of TCM has undergone four developmental stages， exhibiting inherent characteristics such as long-term inevitability， objective standardization， and ecological evolution. By introducing quantitative metrics， digital and intelligent technologies have achieved breakthroughs in TCM knowledge inheritance and innovation， clinical diagnosis and treatment， and herbal medicine supply. The practical applicability of methodological innovations has been empirically validated， though significant disparities exist in technological adaptability and application depth across different fields. Overall， the digital and intelligent transformation of TCM remains in its nascent stage， grappling with multiple structural challenges：weak data foundations， inadequate technological adaptability， incomplete institutional frameworks， shortages of multidisciplinary talent， lagging policies and regulations， and urban-rural digital divide. In order to foster sustainable development and modernization of TCM， this paper establishes a six-dimensional collaborative governance framework of encompassing data， technology， organization， institutions， environment and ethics， which is rooted in data governance and digital governance theories. Future efforts should center on standardization， integration， and ecosystem development to build a data and technology foundation. Focus should be placed on deepening innovation and application of key TCM-specific technologies， while simultaneously strengthening interdisciplinary talent cultivation， improving institutional mechanisms and policy frameworks， and increasing support for rural areas. By adopting a people-centered and technology-empowered approach， we can overcome developmental constraints and unleash the powerful driving force of digital and intelligent technologies for the inheritance of TCM.

Tissue resident memory T(TRM)cells are a class of memory T cells with long life span and non-lymphoid resident characteristics.TRM cells are the first line of defense against secondary infections in human.TRM cells can restrict the transmission of viruses as well as combat against viruses.Rapid evolution of severe acute respiratory syn-drome coronavirus 2(SARS-CoV-2)and post-COVID-19 syndrome could lead to a series of symptoms such as pulmonary fi-brosis,resulting in long-term fall in quality of life.Many studies focused on enhancing the ability to cope with the mutation of SARS-CoV-2 and reducing the incidence of post-COVID-19 syndrome.The relationship between TRM cells and SARS-CoV-2 infection or therapy still remain unknown.It is significant to investigate TRM cells divergence and functions for the development of vaccines.We review the functions and residence properties of TRM cells,as well as their roles in SARS-CoV-2 infection and post-COVID-19 syndrome.In this review,we are dedicated to deepen our understanding of the immune process in SARS-CoV-2 infection and provide a new prospect for the prevention and treatment of post-COVID-19 syndrome.

Objective To analyze the clinical application of computed tomography angiography(CTA)in preoperative planning for laparoscopic radical resection of cancer procedures.Methods Clinical data of 120 patients who underwent laparoscopic radical resection of colon cancer from January 2021 to February 2024 were retrospectively analyzed.Among them,60 patients underwent routine abdominal CT and CTA,while the other 60 patients underwent magnetic resonance imaging(MRI).Pathological findings were used as the gold standard to determine the consistency of CTA in clinical T staging and actual results,as well as its accuracy in evaluating whether the tumor invaded the mesenteric blood vessels and surrounding tissues.Results Using pathological findings as the gold standard,preoperative CTA demonstrated 95.00%diagnostic accuracy(57/60)for T-staging,showing excellent agreement(Kappa=0.925,P<0.05).The preoperative MRI successfully diagnosed 98.33%(59/60)in determining the T staging of colon cancer.There was no significant difference in the number of cases detected by CTA and MRI(χ2=0.26,P>0.05).CTA predicted whether the tumor involved important blood vessels such as superior mesenteric artery,superior mesenteric vein,inferior mesenteric artery,inferior mesenteric vein,as well as surrounding tissues such as abdominal aorta,renal artery,renal vein and splenic artery,which was in good agreement with postoperative pathological results.Especially in predicting mesenteric vascular involvement,the sensitivity,specificity and accuracy of CTA were 94.44%,95.83%and 95.00%,respectively.Conclusion Preoperative CTA for patients undergoing laparoscopic radical resection of colon cancer not only provides clear visualization of T-staging,but also reveals mesenteric vascular anatomy/variants and defines tumor relationships with surrounding structures.This comprehensive assessment offers robust support for surgical planning,enhances laparoscopic procedure safety,and reduces avoidable operative risks.

Clustered regularly interspaced short palindromic repeats(CRISPR)/CRISPR-associated protein 9(Cas9)technology is easy to operate,efficient,and applicable,and has unique advantages in probing the underlying mechanisms of the airways.Bronchial epithelial cells form a physical barrier of lung defense,and their damage or dysfunc-tion involves in the pathogenesis of chronic airway diseases.In recent years,the incidence of chronic airway diseases has increased,but the progress of treatment has been relatively slow,and there is an urgent need to find a therapeutic break-through.The CRISPR/Cas9 system enables precise gene editing and provides a new strategy for chronic airway diseases.In this review,we provide an overview of the application and progress of CRISPR/Cas9 in primary or immortalized bronchial epithelial cells and in vivo animal models in terms of its delivery mode and mechanism,and discuss the development pros-pects and challenges of CRISPR/Cas9,to provide potential future role of this strategy for airway disease treatment.

Objective To observe the efficacy of Cuofeng San in the treatment of anterior circulation cerebral infarction(ACCI)of patients with syndrome of wind and phlegm blocking collaterals.Methods A total of 150 ACCI patients were collected in this study,and they were divided into the control group and the treatment group using a random number table method,with 75 cases in each group.The control group was given standardized intervention according to the stroke diagnosis and treatment guidelines,while the treatment group was treated with modified Cuofeng San on the basis of the control group.Both groups were treated continuously for 2 weeks.The treatment effects were compared between the two groups before and after treatment,including the National Institutes of Health Neurological Impairment Scale(NIHSS)score,Barthel Index(BI)score of daily activity ability,scores of syndrome of wind and phlegm blocking collaterals,serum levels of neuron specific enolase(NSE),S100 calcium binding protein B(S100B),monocyte chemoattractant protein-1(MCP-1)and vascular endothelial cell calcium binding protein(VE-cadherin).Results The total effective rate of ACCI patients was higher in the treatment group than that in the control group(93.3％vs.81.3％,P＜0.05).After 1 week and 2 weeks of treatment,the NIHSS score and wind phlegm obstruction syndrome score decreased in both groups compared to those before treatment,while the BI score increased,and the improvement was more significant in the treatment group(P＜0.05).After the end of the treatment course,serum levels of NSE,S100B,MCP-1 and VE-cadherin decreased compared to those before treatment,and the decrease was more significant in the treatment group(P＜0.05).Conclusion The modified Cuofeng San has a significant effect on the treatment of wind phlegm obstruction syndrome in patients with ACCI acute phase.It can improve neurological function and enhance daily activity ability.

Objective To investigate the value of chest contrast-enhanced CT(C-CECT)combined with artificial intelligence iterative reconstruction(AIIR)for bronchial artery(BA)imaging.Methods Seventy patients who underwent C-CECT were prospectively enrolled.The images were reconstructed with AIIR(AIIR group)and hybrid iterative reconstruction(HIR,HIR group),respectively.The overall image quality,the traceability of BA,the sharpness of BA and the diagnostic confidence of abnormalities of BA were subjectively graded using a 5-point scale by two radiologists,respectively.The subjective scores and inter-observer agreement were compared between groups.The noise(SD)in reconstructed images of thoracic aorta,pulmonary trunk,BA and spinal erectors,the contrast-to-noise ratio(CNR)of the above 3 arteries relative to spinal erectors,and the diameters of BA at the origin,bifurcation and pulmonary hilum were compared between groups.Results The scores of the overall image quality,the traceability of BA,the sharpness of BA and the diagnostic confidence of abnormalities of BA were all significantly higher in AIIR group than those in HIR group(all P＜0.001),all with good inter-observer agreement(Kappa=0.46-0.73).SD of the aorta,pulmonary artery trunk,BA and erector spinal muscle in AIIR group were lower than those in HIR group,while CNR of above 3 arteries were higher than those in HIR group(all P＜0.05).No significant difference of the diameter of BA at each position was found between groups(all P＞0.05),while the consistency of measurement of AIIR group was higher than that of HIR group(intra-class correlation coefficient:0.89-0.94 vs.0.63-0.78).Conclusion C-CECT combined with AIIR could significantly improve imaging quality and diagnostic confidence of BA.

Objective:To investigate the measurement differences between mainstream and sidestream partial pressure of end tidal carbon dioxide(PetCO2)monitoring techniques in mechanically ventilated patients,as well as the correlation with partial pressure of arterial blood carbon dioxide(PaCO2)and clinical applicability,and to provide a basis for the rational selection of monitoring methods in the clinic.Methods:A total of 169 patients who underwent invasive mechanical ventilation in the operating room of the First Affiliated Hospital of Bengbu Medical University from August to November 2024 were selected to be monitored by three monitoring techniques of mainstream PetCO2,sidestream PetCO2 and PaCO2,respectively,and the 243 sets of valid pairwise data monitored by the three monitoring techniques were recorded,analyzed for correlation and deviation,and performed PaCO2 and PetCO2 were stratified and analyzed.Likert scales were used to analyze the subjective ratings of the 3 monitoring techniques of mainstream PetCO2,sidestream PetCO2,and PaCO2 by the 31 health care professionals who used the study.Results:Both mainstream and sidestream PetCO2 correlated with PaCO2(r=0.554,0.515,P<0.05),and mainstream PetCO2 correlated better than sidestream;mainstream PetCO2 was lower than the concurrent PaCO2 by 6.00 mmHg,and the 95%limit of agreement(95%LoA)was±6.28 mmHg,both lower than that of sidestream by 8.24 mmHg and±7.41 mmHg.8.24 mmHg and±7.41 mmHg.The dispersion of sidestream PetCO2 monitoring values was greater,especially at high PaCO2 levels.Mainstream method PetCO2 had the highest correlation with PaCO2 in gynecologic patients(r=0.820,P<0.05),and sidestream method PetCO2 underestimated PaCO2 more markedly in gastrointestinal and hepato-biliary-pancreatic surgery patients.The deviation of oxygenation index≤300 mmHg was significantly greater than that of patients with oxygenation index>300 mmHg,and the tendency of underestimation was more significant at high PaCO2.31 healthcare experts evaluated that the mainstream PetCO2 monitoring method was outstanding in terms of accuracy and real-time,and that the sidestream method of PetCO2 monitoring was advantageous in terms of ease of operation and management of consumables.Conclusion:In patients who receive mechanical ventilation,the precision,accuracy and real-time of mainstream PetCO2 monitoring are better,which is suitable for patients with rapid changes in disease condition or patients at risk of hypercapnia.The sidestream method is suitable for non-intubated or transported patients,but it is easy to be underestimated at high PaCO2,and it needs to be corrected regularly in combination with arterial blood gas.The clinical application should rationally choose monitoring method after a comprehensive assessment based on the patient's disease condition,oxygenation status,and the scenario of use.

Paraplegia caused by spinal cord injury is a serious neurological complication, for which surgery is currently the main treatment method. Due to different surgical approaches, patients are usually expected to maintain a passive prone position for a long time or switch between the supine and prone positions. Affected by multiple factors such as neurogenic sensory disorders, pathological changes in muscle tone and operative duration, the risk of intraoperative acquired pressure injury (IAPI) is significantly increased. Current clinical prevention strategies for IAPI in these patients predominantly focus on localized pressure relief during positioning, lacking systematic, standardized comprehensive prevention protocols or evidence-based guidelines. To address it, Department of Nursing, Orthopedics Branch, China International Exchange and Promotive Association for Medical and Health Care, Spinal Trauma Professional Committee, Orthopedics Branch, Chinese Medical Doctor Association, Nursing Group of Spine and Spinal Cord Professional Committee of Chinese Association of Rehabilitation Medicine organized experts in relevant fields to formulate Guideline for the prevention of intraoperative acquired pressure injury in paraplegic patients with spinal cord injury ( version 2025), based on evidence-based medical evidence and latest research results and clinical practice at home and abroad. Eleven recommendations were put forward from the aspects of preoperative risk assessment, intraoperative prevention strategies, postoperative handover and monitoring, and supportive mechanisms for IAPI prevention, aiming to standardize the prevention measures and management strategies of IAPI in paraplegic patients with spinal cord injury and accelerate the recovery of patients and improve the therapeutic effect.

Objective:To investigate the clinicopathological characteristics, immunophenotypes, diagnostic criteria and differential diagnosis of atrophic kidney-like lesion (AKLL).Methods:Three cases of AKLL were collected from April 2021 to October 2023 at the Xiangya Hospital of Central South University, Changsha, Zhejiang Provincial People′s Hospital, Hangzhou and Ningbo Clinical Pathology Diagnosis Center, Ningbo, China. The clinical, morphological, and immunohistochemical characteristics were analyzed. Relevant literature was also reviewed. A targeted DNA-based next-generation sequencing (a panel of 150 genes) was performed on one of the three cases.Results:There were 1 female and 2 males, aged 30, 57, and 17 years (mean 34.6 years), respectively. The lesions were all incidentally identified during physical or imaging examination. Radiologically, they were all presented as a unilateral renal parenchymal mass. Grossly, the maximum diameters of the lesions were 1.8, 4.0, and 6.5 cm (mean 4.1 cm), respectively. The tumor cut-surfaces were sponge-like, multilocular cystic, and solid, respectively. At low magnification, the lesions were well-circumscribed, while a thick fibromuscular capsule was noted in cases 1 and 3. Cases 1 and 2 were composed of thin-walled cysts or follicular like structures of varying sizes, with the cyst wall lined by flattened and atrophic, or hobnail cells. The luminal spaces contained dense eosinophilic secretion and associated calcifications, while some cysts contained discohesive cells floating in the eosinophilic material. The tissue between the cysts showed predominantly small atrophic tubular structures. Case 3 was almost entirely composed of atrophic and collapsed tubular structures with focal cyst formation, imparting a solid sheets growth pattern under low magnification. Immunohistochemical staining revealed that the cyst lining cells and the intracystic floating cells were WT1 positive, PAX8 negative and CK7 negative, while the atrophic renal tubules were WT negative, PAX8 positive and CK7 positive. Targeted next-generation sequencing in case 1 showed no significant genetic abnormalities. All 3 patients underwent partial nephrectomy. No evidence of recurrence or metastasis was found with a follow-up of 17 to 36 months.Conclusions:AKLL is a rare and novel benign renal disease. It is easily misdiagnosed as a renal neoplasm grossly and histologically. Careful morphological observation combined with characteristic immunophenotypes can aid in its diagnosis and differential diagnosis.

The interaction between skeletal aging and systemic aging has emerged as a frontier in the field of aging biology research.Recent studies have indicated that bones serve not only as mechanical support organs but also as endocrine organs that regulate systemic homeostasis through bone-derived factors.This review systematically elaborates the characteristics and mechanisms of skeletal aging, including tissue structural remodeling, cellular phenotypic changes, microenvironmental disruption, and molecular network disorders, etc.In aging organisms, bones interact with other organs to form a "bone-system aging axis", thereby promoting the occurrence and development of geriatric comorbidities.Accordingly, multi-target intervention strategies targeting the "bone-system aging axis" show the potential in decelerating the progression of systemic aging.In-depth research on the characteristic changes in inter-organ communication during the aging process of the body is not only conducive to facilitating the development of more comprehensive systemic anti-aging strategies, but also provides a new perspective for treating geriatric comorbidities and achieving healthy aging.
