Objective·To investigate the clinicopathologic features,gene mutation profile,and real-world survival prognosis of diffuse large B-cell lymphoma(DLBCL)with pulmonary involvement.Methods·The clinical data of 110 patients with newly diagnosed,pathologically confirmed DLBCL and pulmonary involvement at Ruijin Hospital,Shanghai Jiao Tong University School of Medicine,between August 2003 and December 2022 were retrospectively collected and analyzed.Evaluation of the efficacy of treatment,survival analyses,and univariate and multivariate analyses were performed in 88 patients who received a first-line regimen based on rituximab in combination with cyclophosphamide,doxorubicin/epirubicine,vincristine,and prednisone(R-CHOP).A total of 74 patients underwent targeted DNA sequencing of 55 lymphoma-related genes and were evaluated for mutations.Results·Among the 110 patients,72(65.5%)were>60 years old,52(47.3%)were female,92(83.6%)presented with Ann Arbor stage Ⅲ?Ⅳ,20(18.2%)had ECOG scores≥2,75(68.2%)had elevated lactate dehydrogenase(LDH)levels,79(71.8%)had≥2 extranodal involvements,32(31.4%)were classified as germinal center B-cell subtype,22(26.8%)were diagnosed with double expressor lymphoma,and 4(4.6%)with double-hit lymphoma.Among the patients treated with R-CHOP-based first-line regimens,the objective response rate(ORR)was 68.2%,the 5-year progression-free survival(PFS)rate was 43.7%,and the 5-year overall survival(OS)rate was 65.4%.Univariate analysis showed that elevated LDH and ECOG score≥2 were poor prognostic factors for PFS and OS,and mutations in PIM1 and CD79B were poor prognostic factors for PFS among high-frequency mutations.Multivariate analysis showed that elevated LDH was an independent adverse prognostic factor for PFS(HR=2.47,95%CI 1.28?4.77)and OS(HR=2.71,95%CI 1.21 ? 6.07).Targeted sequencing results showed that PIM1(25.7%),MYD88(24.3%),TP53(18.9%),CD79B(17.6%),KMT2D(17.6%),and TNFAIP3(16.2%)were the high-frequency mutations with mutation rates over 15%.Conclusion·Elevated LDH is an independent adverse prognostic factor for PFS and OS in DLBCL with pulmonary involvement.Mutations in PIM1,MYD88,TP53,CD79B,KMT2D,and TNFAIP3 are frequently observed in this population.

Objective To explore the similarities and differences in clinical efficacy and mRNA transcriptomics characteristics between acupuncture and shallow needling at non-acupoints and to provide a basis for determining whether shallow needling at non-acupoints is suitable as a sham acupuncture control in acupuncture clinical trials.Methods Eighty patients with chronic spontaneous urticaria(CSU)who visited the Dermatology Department of the Affiliated Hospital of Chengdu University of Traditional Chinese Medicine between July 8,2018 and to July 29,2019,were included.The patients were randomly divided into the acupuncture group(n=41)and the sham acupuncture group(n=39)using a computerized complete random design.Additionally,12 healthy individuals were included as the healthy control group.For patients in the acupuncture group,"Baihui(GV20),""Shenting(GV24),""Zhongwan(CV12),"and bilateral"Quchi(LI11),""Tianshu(ST25),""Xuehai(SP10),""Zusanli(ST36),"and"Sanyinjiao(SP6)"were selected for regular acupuncture.The sham acupuncture group received non-acupoint shallow needling at eight non-acupoints on the head,upper limbs,lower limbs,and abdomen.Both groups underwent daily treatment,with five consecutive days constituting one treatment course followed by a two-day interval.A total of two courses were administered.The urticaria activity score(UAS)was used to evaluate wheals and pruritus,whereas the visual analog scale(VAS)score was used to evaluate the degree of pruritus.Blinding effectiveness was also evaluated.Based on clinical evaluation and sample quality,serum samples from six patients in each treatment group before and after the intervention,along with those from six healthy individuals,were selected for RNA sequencing using the BGISEQ-500 sequencer.Differentially expressed mRNAs were identified using the"DEGseq"software package,and the similarities and differences in mRNA expression between the two groups were analyzed.Results UAS and VAS scores decreased in both groups at 1,2,3,and 4 weeks of treatment compared with before treatment(P＜0.01).The decrease in UAS and VAS scores in both groups was time-dependent(P＜0.01)but not related to the grouping or the interaction between grouping and time(P＞0.05).By the end of the second week of treatment,the number of patients in both groups who believed they had received true acupuncture was similar between the two groups,with no significant difference.mRNA transcriptomic sequencing revealed that,before and after treatment,the enrichment types and degrees of differentially expressed mRNA were similar between the acupuncture and sham acupuncture groups at the biological process,cellular component,and molecular function levels.In terms of biological processes,both groups were commonly enriched in coagulation,hematoma,oxygen transport,and gas transport.In terms of cellular components,both groups exhibited enrichment in hemoglobin complexes,platelet alpha granules,extracellular exosomes,extracellular organelles,and extracellular vesicles.At the molecular function level,both groups were commonly enriched in actin filament-binding substances,haptoglobin,peroxidase activity,and oxygen blood binding.In the Kyoto Encyclopedia of Genes and Genomes(KEGG)pathway enrichment analysis,both groups showed common enrichment in multiple entries such as cytokine-cytokine receptor interaction,ECM-receptor interaction,microRNAs in cancer,proteoglycans in cancer,bladder cancer,and malaria.Conclusion Acupuncture and sham acupuncture exhibited similar clinical treatment effects and mRNA transcriptomics profiles.In the design of acupuncture clinical trials,disease specificity should be carefully considered.Sham acupuncture control using non-acupoint shallow needling may not be suitable for skin diseases such as urticaria.

ObjectiveTo analyze the data structure and standards of rehabilitation outpatient medical records, to provide data support for improving the quality of rehabilitation outpatient care and developing medical insurance payment policies. MethodsBased on the normative documents issued by the National Health Commission, Basic Standards for Medical Record Writing and Standards for Electronic Medical Record Sharing Documents, in accordance with the Quality Management Regulations for Outpatient (Emergency) Diagnosis and Treatment Information Pages (Trial), reference to the framework of the World Health Organization Family of International Classifications (WHO-FICs), the data framework and content of rehabilitation outpatient medical records were determined, and the data standards were discussed. ResultsThis study constructed a data framework for rehabilitation outpatient medical records, including four main components: patient basic information, visit process information, diagnosis and treatment information, and cost information. Three major reference classifications of WHO-FICs, International Classification of Diseases, International Classification of Functioning, Disability and Health, and International Classification of Health Interventions,were used to establish diagnostic standards and standardized terminology, as well as coding disease diagnosis, functional description, functional assessment, and rehabilitation interventions, to improve the quality of data reporting, and level of quality control in rehabilitation. ConclusionThe structuring and standardization of rehabilitation outpatient medical records are the foundation for sharing of rehabilitation data. The using of the three major classifications of WHO-FICs is valuable for the terminology and coding of disease diagnosis, functional description and assessment, and intervention in rehabilitation outpatient medical records, which is significant for sharing and interconnectivity of rehabilitation outpatient data, as well as for optimizing the quality and safety of rehabilitation medical services.

ObjectiveTo explore the standardization of inpatient rehabilitation medical record summary sheet, encompassing its structure, content and data standards, to enhance the standardization level of inpatient rehabilitation medical record summary sheet, improve data reporting quality, and provide accurate data support for medical insurance payment, hospital performance evaluation, and rehabilitation discipline evaluation. MethodsBased on the relevant specifications of the National Health Commission's Basic Norms for Medical Record Writing, Specifications for Sharing Documents of Electronic Medical Records, and Quality Management and Control Indicators for Inpatient Medical Record Summary Sheet (2016 Edition), this study analyzed the structure and content of the inpatient rehabilitation medical record summary sheet. The study systematically applied the three major reference classifications of the World Health Organization Family of International Classifications, International Classification of Diseases (ICD-10/ICD-11, ICD-9-CM-3), International Classification of Functioning, Disability and Health (ICF), and International Classification of Health Interventions (ICHI Beta-3), for disease diagnosis, functional description and assessment, and rehabilitation intervention, forming a standardized terminology system and coding methods. ResultsThe inpatient rehabilitation medical record summary sheet covered four major sections: inpatient information, hospitalization information, diagnosis and treatment information, and cost information. ICD-10/ICD-11 were the standards and coding tools for admission and discharge diagnoses in the inpatient rehabilitation medical record summary sheet. The three functional assessment tools recommended by ICD-11, the 36-item version of World Health Organization Disability Assessment Schedule 2.0, Brief Model Disability Survey and Generic Functioning domains, as well as ICF, were used for rehabilitation functioning assessment and the coding of outcomes. ICHI Beta-3 and ICD-9-CM-3 were used for coding surgical procedures and operations in the medical record summary sheet, and also for coding rehabilitation intervention items. ConclusionThe inpatient rehabilitation medical record summary sheet is a summary of the relevant content of the rehabilitation medical record and a tool for reporting inpatient rehabilitation data. It needs to be refined and optimized according to the characteristics of rehabilitation, with necessary data supplemented. The application of ICD-11/ICD-10, ICF and ICHI Beta-3/ICD-9-CM-3 classification standards would comprehensively promote the accuracy of inpatient diagnosis of diseases and functions. Based on ICD-11 and ICF, relevant functional assessment result data would be added, and ICHI Beta-3/ICD-9-CM-3 should be used to code rehabilitation interventions. Improving the quality of rehabilitation medical records and inpatient rehabilitation medical record summary sheet is an important part of rehabilitation quality control, and also lays an evidence-based data foundation for the analysis and application of inpatient rehabilitation medical record summary sheet.

Cardiac surgery patients often present with multiple comorbidities,the risk of periop-erative complications and the complexity of postoperative rehabilitation have significantly increased,posing higher demands on comprehensive perioperative management.Preoperative exercise pre-reha-bilitation,as a multidisciplinary collaborative intervention strategy,has been demonstrated to signifi-cantly improve the clinical prognosis of patients undergoing elective cardiac surgery by enhancing their cardiopulmonary function,muscle strength,and overall physiological functional reserve,thereby in-creasing the body's tolerance to surgical stress.Although phase-specific research achievements have been made domestically and internationally in the field of exercise pre-rehabilitation,its standardized implementation and clinical translation on a global scale still face numerous obstacles,necessitating systematic review and in-depth exploration.Therefore,this study aimed to conduct a systematic re-view of the intervention protocols,clinical efficacy,safety,and feasibility of preoperative exercise pre-rehabilitation in patients undergoing elective cardiac surgery,with the goal of providing theoretical evidence and practical references for optimizing perioperative management pathways and promoting the implementation of enhanced recovery after surgery concepts.

Objective: To establish a mouse model of lung injury induced by self-antigens and explore its pathological mechanisms to provide a reliable animal model for studying the pathogenesis of rheumatoid arthritis-associated interstitial lung disease(RA-ILD). Methods: The mice were injected intradermal with antigenemulsion made of complete freund′s adjuvant(CFA) and lung tissue protein, and the emulsion prepared with incomplete Freund′s adjuvant(IFA) was used to enhance immunity. HE staining was used to observe the histopathological changes in the mice. Masson staining was used to detect pulmonary fibrosis. The mRNA levels of rheumatoid factor(RF), krebs von den lungen-6(KL-6) and surfactant protein D(SP-D) were detected by qPCR. The levels of ACPA, IgG1, IgG2a and IgG3 antibodies were detected by ELISA. The changes of inflammatory cells and α-smooth muscle actin(α-SMA)expression in lung tissue were detected by immunofluorescence staining. The protein expression levels of Collagen I and α-SMA were detected by Western blot. The changes of immune cells were detected by flow cytometry. Results: HE staining showed that inflammatory cell infiltration increased and tissue structure changed significantly in lung tissue after the model was established by self-lung tissue antigen. Masson staining showed increased collagen deposition in lung tissue of model mice. qPCR tests revealed elevated mRNA levels of RF, KL-6 and SP-D. ELISA tests revealed elevated levels of ACPA, IgG1 and IgG3 antibodies. Immunofluorescence results showed that monocytes and T cells increased, and α-SMA expression increased in the model group. Western blot results showed increased protein expressions of Collagen Ⅰ and α-SMA. The flow cytometry results showed an increase in T cells and monocytes in the lung tissue. Conclusion The mouse model of lung injury induced by self-antigens is successfully established, and T cells and monocytes may be involved in the occurrence and progression of the disease.

BACKGROUND:Due to the lack of blood supply to tendons and the low repair ability of tendon cells,the repair cycle of tendon tissue is long.With the maturity of decellularization technology,decellularized extracellular matrix is receiving increasing attention in the fields of tissue engineering and regenerative medicine.Due to its high activity,low immunogenicity,and ability to support cell attachment,proliferation,and differentiation,decellularized tendon scaffolds are expected to promote tendon repair.OBJECTIVE:To summarize the biological characteristics of decellularized tendon scaffolds,elucidate the mechanism by which decellularized tendon scaffolds promote tendon healing,and explain the application methods and future limitations of decellularized tendon scaffolds in combination with other materials.METHODS:Relevant literature was retrieved from China National Knowledge Infrastructure and PubMed databases using the Chinese search terms"tendon injury,tendon repair,tendon disease,decellularized tendon scaffold"and English search terms"tendon injury,tendon repair,tendinopathy,decellularized tendon scaffold,decellularized tendon scaffolds."By reading and screening relevant literature,77 articles were ultimately included for result analysis.RESULTS AND CONCLUSION:(1)Decellularization technology can be divided into physical treatment,chemical treatment,and biological procedures.(2)Decellularized tendon scaffolds,as a common biomedical material,have certain biocompatibility,biodegradability,and biomechanical properties,which provide a prerequisite and foundation for tendon injury repair.(3)Decellularized tendon scaffolds can alleviate the inflammatory response of tissues,promote the adhesion,proliferation,and differentiation of bone marrow mesenchymal stem cells/tendon derived stem cells,and maintain the biomechanical properties of tissues.(4)Decellularized tendon scaffolds can be used in combination with other materials,such as electrospinning,hydrogel,stem cell implantation,and 3D printing technology.(5)Future research can further investigate its pathogenic mechanism and improve tendon tissue repair by combining other biomaterials with decellularized tendon scaffold applications.

Objective To investigate the possible association between cross-domain associative memory(AM)impairment and hippocampal subfield volumes in patients with schizophrenia(SCZ).Methods We enrolled 28 SCZ patients from Shanghai Mental Health Center,Shanghai Jiao Tong University School of Medicine,and 28 healthy controls(HCs)between 2019 and 2021.Based on an innovative AM paradigm and automated segmentation,3D-T1 weighted data of the objects were processed with PhiPipe and FreeSurfer.Differences in subfield volums between the two groups were analyzed using ANCOVA,while their relationship with AM scores was assessed using Pearson correlation.Results SCZ patients exhibited significantly poorer AM performance across three conditions compared with HCs.Marginally significant reductions were observed in the total volume of bilateral hippocampus,encompassing both the hippocampal head and body.Significant volume reductions were identified in the bilateral presubiculum and parasubiculum.The volumes of bilateral presubiculum head(r=0.273,P=0.042),parasubiculum(r=0.397,P=0.002),and CA1 head(r=0.382,P=0.004)exhibited positive correlations with cross-domain AM performance.Conclusion The bilateral presubiculum and parasubiculum,as hippocampal subregions significantly associated with cross-modal AM deficits in SCZ,may play a crucial role in the pathology of AM.
