To improve the consistency of outcome documentation and address the potential for outcome reporting bias in clinical trials involving integrative Chinese and Western medicine (ICWM) for ulcerative colitis (UC), we aim to develop a customized core outcome set (COS) that incorporates input from various stakeholders. The study design of this COS has been informed by the Core Outcome Measures in Effectiveness Trials Initiative Handbook, with adherence to the guidelines from the Core Outcome Set-STAndards for Reporting statement and Core Outcome Set-STAndardised Protocol Items recommendations. Five groups of stakeholders will be invited to participate in the development of COS for clinical trials with ICWM for UC, including healthcare professionals, patients, COS developers, COS users, and methodologists. The process will involve five stages: (1) conducting a systematic review of outcomes reported in clinical trials and protocols to develop a list of potential outcome domains; (2) conducting semi-structured interviews to obtain important outcomes; (3) choosing the most important outcomes by conducting three-round Delphi surveys; (4) achieving a consensus in a face-to-face meeting to discuss the final COS; and (5) publication, dissemination and implementation of COS. Consequently, this specialized COS will be applicable to clinical trials involving both traditional Chinese medicine (TCM) and ICWM interventions.

Objective To investigate the mechanism underlying gasdermin E(GSDME)-mediated pyroptosis in radiation-induced intestinal injury and to find out whether gasdermin(GSDM)family members regulate pyroptosis through similar signaling pathways.Methods Human normal colon epithelial cells(NCM460)and human colon cancer cells(HT-29)were exposed to radiation of different doses and durations before pyroptosis indicators were evaluated by observing pyroptotic bubbles,cell survival,and the cleavage of pyroptosis execution proteins.HT-29 cells overexpressing GSDME were subjected to radiation,followed by enrichment analysis of pyroptosis-related differentially expressed genes using RNA-seq.Results Radiation induced substantial pyroptosis in NCM460 cells.Overexpression of GSDME in HT-29 cells resulted in substantial radiation-induced pyroptosis.The pyroptosis state of human intestinal cells was simulated in the HT-29 model cell line.Overexpressions of GSDME-N and GSDMD-N resulted in the expression of more than 50％ of the differentially expressed genes in the pyroptosis state.Sequencing analysis showed that the genes in the pyroptosis state were mainly overrepresented in immune response,inflammatory response,and Rapl signaling pathway.Conclusion GSDME activation can mediate radiation-induced pyroptosis by producing GSDME-N fragments.GSDM family members participate in pyroptosis in a similar mode of regulation.Furthermore,radiation-induced activation of GSDME/D may regulate pyroptosis through immune response,inflammatory response,and Rap1 signaling pathway.

Objective To explore effect of nerve growth factor(NGF)antibody on knee osteoarthritis(KOA)pain model was evaluated by in vitro model.Methods Thirty male SPF rats aged 28-week-old were divided into blank group(10 rats with anesthesia only).The other 20 rats were with monoiodoacetate(MIA)on the right knee joint to establish pain model of OA,and were randomly divided into control group(injected intraperitoneal injection of normal saline)and treatment group(injected anti-NGF)intraperitoneal after successful modeling,and 10 rats in each group.All rats were received retrograde injection of fluorogold(FG)into the right knee joint.Gait was assessed using catwalk gait analysis system before treatment,1 and 2 weeks after treatment.Three weeks after treatment,right dorsal root ganglia(DRG)were excised on L4-L6 level,immunostained for calcitonin gene-related peptide(CGRP),and the number of DRGS was counted.Results In terms of gait analysis using cat track system,duty cycle,swing speed and print area ratio in control and treatment group were significantly reduced compared with blank group(P＜0.05).Compared with control group,duty cycle and swing speed of treatment group were significantly im-proved(P＜0.05),and there was no significant difference in print area ratio between treatment group and blank group(P＞0.05).The number of FG-labeled DRG neurons in control group was significantly higher than that in treatment group and blank group(P＜0.05).The expression of CGRP in control group was up-regulated,and differences were statistically significant compared with treatment group(P＜0.05).Conclusion Intraperitoneal injection of anti-NGF antibody inhibited gait injury and upregulation of CGRP in DRG neurons.The results suggest that anti-nerve growth factor therapy may be of value in treating knee pain.NGF may be an important target for the treatment of knee OA pain.

This study aimed to investigate the role and mechanism of sappanone A (SA) in regulating renal ischemia-reperfusion injury (IRI) in rats. The animal experiment has been approved by the Ethics Committee of Suzhou Wujiang District Children's Hospital (approval number: 2022010). First, hematoxylin-eosin (H&E) staining was used to evaluate the effects of SA on IRI, and renal damage was scored. Serum creatinine (SCr), blood urea nitrogen (BUN) and cystatin C (Cystatin C) were analyzed. The effect of sappanone A on the apoptosis of renal tubular epithelial cells induced by IRI was analyzed by TUNEL staining. Protein expression levels of p-JNK/JNK, p-ERK/ERK, Bcl2, Bax and cleaved-caspase 3 in renal tissues were detected by Western blot. Finally, H&E staining, serological analysis, TUNEL staining and Western blot were used to determine whether JNK activator anisomycin could reverse the effect of SA on IRI in rats. The results showed SA significantly reduced the renal tubule injury caused by ischemia-reperfusion, and decreased the level of SCr, BUN and Cys C in serum. TUNEL staining showed that SA significantly reduced the apoptosis of renal tubular epithelial cells induced by IRI. Western blot analysis of kidney tissue showed that SA significantly promoted the expression of apoptosis inhibiting protein Bcl2 and inhibited the expression of apoptosis-promoting proteins Bax and cleaved-caspase 3. Further analysis elucidated that SA did not affect the phosphorylation of ERK but decreased the phosphorylation of JNK. Finally, H&E staining, serological analysis, TUNEL staining and Western blot confirmed that JNK activator anisomycin could reverse the alleviating effect of SA on IRI in rats. The above findings suggest that SA could alleviate IRI in rats by inhibiting JNK phosphorylation.

Objective:To compare the prognostic value of two predictive models based on C-reactive protein(CRP)and albumin(ALB),namely the CRP to ALB ratio(CAR)and the Glasgow prognostic score(GPS),in newly diagnosed patients with diffuse large B-cell lymphoma(DLBCL).Methods:The data of newly diagnosed DLBCL patients admitted to our center from May 2014 to January 2022 were reviewed.A total of 111 patients who completed at least 4 cycles of R-CHOP or R-CHOP-like chemotherapy with detailed clinical,laboratory data and follow-up information were included.The receiver operating characteristic(ROC)curve was performed to evaluate the predictive value of pre-treatment CAR on disease progression and survival.Furthermore,the association between CAR and baseline clinical,laboratory characteristics of patients was evaluated,and progression-free survival(PFS)and overall survival(OS)were compared between different CAR and GPS subgroups.Finally,the univariate and multivariate COX propor-tional hazard regression models were used to analyze the factors affecting disease outcomes.Results:ROC curve showed that the area under the curve(AUC)of CAR predicting PFS and OS in DLBCL patients was 0.687(P=0.002)and 0.695(P=0.005),respectively,with the optimal cut-off value of 0.11 for both predicting PFS and OS.Compared with the lower CAR(＜0.11)group,the higher CAR(≥0.11)group had more clinical risk factors,including age＞60 years(P=0.025),ECOG score ≥2(P=0.004),Lugano stage Ⅲ-Ⅳ(P＜0.001),non-germinal center B-cell-like(non-GCB)subtype(P=0.035),elevated lactate dehydrogenase(LDH)(P＜0.001),extranodal involved site＞1(P=0.004)and IPI score＞2(P＜0.001).The interim response evaluation of patients showed that the overall response rate(ORR)and complete response rate(CRR)in the lower CAR group were both significantly better than those in the higher CAR group(ORR:96.9％vs 80.0％,P=0.035;CRR:63.6％vs 32.5％,P=0.008).With a median follow-up of 24 months,patients with lower CAR had significantly longer median PFS and OS than those with higher CAR(median PFS:not reached vs 67 months,P=0.0026;median OS:not reached vs 67 months,P=0.002),while there was no statistical difference in PFS(P=0.11)and OS(P=0.11)in patients with GPS of 0,1,and 2.Multivariate Cox regression analysis indicated that only sex(male)and IPI score＞2 were independent risk factors for both PFS and OS.Conclusion:CAR is significantly correlated with disease progression and survival in DLBCL patients;And compared with GPS,CAR has more advantages in predicting disease outcomes in DLBCL patients.

Objective:To compare the efficacy and safety of flumatinib (FM)and imatinib (IM)as first-line treatment in newly-diagnosed patients with chronic myeloid leukemia in chronic phase (CML-CP ) in real world. Methods:A total of 84 newly-diagnosed CP-CML patients in our center from December 2019 to December 2022 were retrospectively analyzed.Among them,32 cases received FM as first-line treatment,and 52 cases received IM. Molecular response (MR),disease progression,survival and incidence of adverse events (AEs)were compared between the two groups.Results:At 3 months of treatment,the incidences of early molecular response (EMR ),MR2.0 and MR3.0 were 96.7％,70.0％ and 20.0％ in FM group,respectively,which were significantly higher than 77.1％,29. 2％ and 0 in IM group (all P<0.05 ).At 6,9 and 12 months of treatment,the incidences of major molecular response (MMR)in FM group were 68.2％,85.7％ and 90.0％,respectively,which were significantly higher than 22.9％,34.0％ and 51.1％ in IM group (all P<0.01).The median time to achieve MMR in FM group was 6(6-9)months,which was significantly shorter than 18(12-22)months in IM group (P<0.001 ).The 3-year progression-free survival rate and 3-year event-free survival rate in FM group were 100％ and 68.8％,respectively,while in IM group were 98.1％ and 55.8％.There were no significant differences between the two groups (P>0.05). The incidence of grade 3-4 hematologic AEs in FM group was 21 .9％,which was slightly lower than 25.0％ in IM group,but the difference was not significant (P>0.05 ).Conclusion:In real clinical practice,FM as first-line treatment achieves MMR earlier than IM,and exhibits good safety profile in newly-diagnosed CML-CP patients,which potentially leads to improved long-term survival and treatment-free remission.

OBJECTIVE: To explore the role of the CMTM2 gene in regulating testicular spermatogenesis in the mouse model of experimental autoimmune orchitis (EAO). METHODS: We constructed an EAO model in CMTM2 knockout and wild-type (WT) mice, studied the immunological reproductive phenotype and examined the number, morphology and activity of the sperm generated in the CMTM2 knockout mice. We assessed the infiltration of macrophages and lymphocytes in the testis tissue sections and Leydig cells, and determined the expression levels of CMTM2 in the homozygous knockout (KO), heterozygous and WT mice by RT-PCR, Western blot and Northern blot. RESULTS: Statistically significant differences were observed in the long testicular axis and the number of sperm generated between the KO and WT mice after reaching adulthood (P<0.05). The total numbers of macrophages and lymphocytes were markedly increased, while sperm motility and the percentage of morphologically normal sperm remarkably decreased in the testis of the KO mouse model compared with those in the WT mouse model of EAO. CONCLUSION The CMTM2 gene, as a regulator of spermatogenesis, is highly expressed in adult male mice and plays an important role in the maintenance of spermatogenesis. Moreover, decreased expression products of the CMTM2 gene may weaken spermatogenesis under chronic inflammation conditions.

Objective:To analyze the accuracy of a single-lead electrocardiogram (iECG) algorithm based on intelligent wristwatch in identifying sinus tachycardia and atrial fibrillation (AF) with rapid ventricular rate.Methods:In this non-randomized control trial, 642 patients aged ≥18 years were enrolled in the General Hospital of Chinese PLA between December 15, 2020 and May 30, 2022, with sinus tachycardia or rapid ventricular rate of AF (ranging from 111 to 145 beats/min for sinus tachycardia, from 110 to 150 beats/min for rapid ventricular rate of AF, respectively). The patients wore Huawei Watch GT2 Pro smartwatches on their left wrists, and the physiological signals detected by the smartwatches in a relaxed state were used as the measured data. The iECG algorithm developed by Huawei was used for identification. Simultaneously, 12-lead electrocardiograms (12L-ECG) were performed, and two cardiologists served as the gold standard for interpretation. Three participants who did not meet the inclusion criteria were excluded based on the detection results, and a total of 639 participants were included in the study. The accuracy of the algorithm in identifying sinus tachycardia and rapid ventricular rate AF was evaluated using metrics such as recall rate, precision rate, macro F1 score for multi-class classification.Results:Among 639 subjects, there were 469 males and 170 females. There were 389 cases of sinus tachycardia and 250 cases of rapid ventricular rate AF, with a mean age of (46.53±13.32) years. The recall rate, precision rate, and F1 value of iECG algorithm in identifying sinus tachycardia was 98.7%, 99.2% and 99.0%, respectively, while it was 98.8%, 98.0% and 98.4%, respectively for AF with rapid ventricular rate. The macro F1 of AF with rapid ventricular rate and sinus tachycardia was 98.7%. The iECG based on the intelligent wristwatch showed good consistency with the corresponding 12L-ECG waveforms.Conclusion:The intelligent wristwatch-based iECG algorithm can effectively identify sinus tachycardia and rapid ventricular rate AF, demonstrating good accuracy.

Objective: This cross-sectional investigation aimed to determine the incidence, clinical characteristics, prognosis, and related risk factors of olfactory and gustatory dysfunctions related to infection with the SARS-CoV-2 Omicron strain in mainland China. Methods: Data of patients with SARS-CoV-2 from December 28, 2022, to February 21, 2023, were collected through online and offline questionnaires from 45 tertiary hospitals and one center for disease control and prevention in mainland China. The questionnaire included demographic information, previous health history, smoking and alcohol drinking, SARS-CoV-2 vaccination, olfactory and gustatory function before and after infection, other symptoms after infection, as well as the duration and improvement of olfactory and gustatory dysfunction. The self-reported olfactory and gustatory functions of patients were evaluated using the Olfactory VAS scale and Gustatory VAS scale. Results: A total of 35 566 valid questionnaires were obtained, revealing a high incidence of olfactory and taste dysfunctions related to infection with the SARS-CoV-2 Omicron strain (67.75%). Females(χ2=367.013, P<0.001) and young people(χ2=120.210, P<0.001) were more likely to develop these dysfunctions. Gender(OR=1.564, 95%CI: 1.487-1.645), SARS-CoV-2 vaccination status (OR=1.334, 95%CI: 1.164-1.530), oral health status (OR=0.881, 95%CI: 0.839-0.926), smoking history (OR=1.152, 95%CI=1.080-1.229), and drinking history (OR=0.854, 95%CI: 0.785-0.928) were correlated with the occurrence of olfactory and taste dysfunctions related to SARS-CoV-2(above P<0.001). 44.62% (4 391/9 840) of the patients who had not recovered their sense of smell and taste also suffered from nasal congestion, runny nose, and 32.62% (3 210/9 840) suffered from dry mouth and sore throat. The improvement of olfactory and taste functions was correlated with the persistence of accompanying symptoms(χ2=10.873, P=0.001). The average score of olfactory and taste VAS scale was 8.41 and 8.51 respectively before SARS-CoV-2 infection, but decreased to3.69 and 4.29 respectively after SARS-CoV-2 infection, and recovered to 5.83and 6.55 respectively at the time of the survey. The median duration of olfactory and gustatory dysfunctions was 15 days and 12 days, respectively, with 0.5% (121/24 096) of patients experiencing these dysfunctions for more than 28 days. The overall self-reported improvement rate of smell and taste dysfunctions was 59.16% (14 256/24 096). Gender(OR=0.893, 95%CI: 0.839-0.951), SARS-CoV-2 vaccination status (OR=1.334, 95%CI: 1.164-1.530), history of head and facial trauma(OR=1.180, 95%CI: 1.036-1.344, P=0.013), nose (OR=1.104, 95%CI: 1.042-1.171, P=0.001) and oral (OR=1.162, 95%CI: 1.096-1.233) health status, smoking history(OR=0.765, 95%CI: 0.709-0.825), and the persistence of accompanying symptoms (OR=0.359, 95%CI: 0.332-0.388) were correlated with the recovery of olfactory and taste dysfunctions related to SARS-CoV-2 (above P<0.001 except for the indicated values). Conclusion: The incidence of olfactory and taste dysfunctions related to infection with the SARS-CoV-2 Omicron strain is high in mainland China, with females and young people more likely to develop these dysfunctions. Active and effective intervention measures may be required for cases that persist for a long time. The recovery of olfactory and taste functions is influenced by several factors, including gender, SARS-CoV-2 vaccination status, history of head and facial trauma, nasal and oral health status, smoking history, and persistence of accompanying symptoms.
