Peripheral T-cell lymphoma, not otherwise specified (PTCL-NOS) is the most common subtype of peripheral T-cell lymphoma. The overall incidence rate of this disease is low and the heterogeneity is strong. At present, its diagnosis mainly relies on exclusive diagnosis. Clinically, the first-line treatment of PTCL-NOS mostly refers to CHOP-like chemotherapy regimens for B-cell non-Hodgkin lymphoma, but its efficacy is unsatisfactory, with high recurrence rate and poor long-term survival. The widespread application of new targeted drugs and antibody conjugated drugs, such as chidamide, pralatrexate and brentuximab vedotin have improved the therapeutic effects of patients to some extent. However, the prognosis of relapsed/refractory patients is still not satisfactory. This article reviews the pathological characteristics, immunophenotype, genetic characteristics, clinical features, and treatment progress of PTCL-NOS.

Objective To construct a trajectory model for the changes in body roundness index(BRI)of elderly people in China from 2011 to 2018 based on the data derived from Chinese Longitudinal Healthy Longevity Survey(CLHLS),and analyze the influencing factors of different BRI trajectories.Methods Based on the longitudinal cohort data from the CLHLS platform,group-based trajectory model(GBTM)analysis was used to construct longitudinal change trajectories of 3 waves of BRI(2011,2014,and 2018)that meet our research criteria.Unordered multinomial logistic regression analysis was employed to identify the influencing factors of different BRI trajectories.Results A total of 2 512 valid samples were included in the analysis.The BRI trajectory of Chinese elderly people fitted by GBTM was optimally grouped into low-,medium-,and high-level growth trajectory models.There were statistically significant differences among different BRI trajectory groups in gender,length of education,resident place,living with spouse,retirement pension,sleep quality,smoking history,drinking history,continuous exercise,frequency of fruit consumption,frequency of salt-preserved vegetables consumption,and"fruit+protein"dietary patterns(P<0.05).Disordered multiclass logistic regression analysis found that,using the low-level growth trajectory model as a reference,males and those with a history of smoking were less likely to exhibit moderate to high growth levels of BRI trajectories;Elderly people with retirement pensions were more likely to exhibit a moderate to high growth level of BRI trajectory;People with a history of alcohol consumption were more likely to exhibit a moderate steady growth level of BRI trajectory;People with longer than 10 years of education were less likely to exhibit a high level of growth in the BRI trajectory,while urban residents and those who frequently consumed fruits and salted vegetables were more likely to exhibit a high level of growth in the BRI trajectory.Conclusion The trajectory of BRI changes among elderly people in China from 2011 to 2018 can be divided into 3 groups,which are influenced by multiple factors such as gender,resident place,and length of education.It is necessary to pay attention to and make measures in advance to improve the quality of life in the elderly.Countermeasures It is advisable to incorporate BRI as a core indicator in elderly health monitoring systems,establish a dynamic management mechanism for high-risk populations,and implement precision-targeted lifestyle interventions and health guidance.

Background and purpose:Long non-coding RNA(lncRNA)LINC01410,with a length of 647 bp,participates in a variety of tumor biological processes.However,the role and mechanism of LINC01410 involved in esophageal squamous cell carcinoma(ESCC)remain unclear.This study aimed to explore the potential mechanism of LINC01410 promoting ESCC proliferation and invasion,to provide a potential prognostic indicator and therapeutic target for individuals with ESCC.Methods:Gene Expression Profiling Interactive Analysis 2(GEPIA2)databases were used to analyze the expression of LINC01410 and overall survival in esophageal squamous cell carcinoma data set in the Cancer Genome Atlas(TCGA).Gene Set Enrichment Analysis(GSEA)was performed to identify the underlying signaling pathways involved in the biological effects of LINC01410 in ESCC.A total of 62 pairs of ESCC tissues and paracancerous tissues from ESCC patients who underwent radical surgery in the Department of Thoracic Surgery at the First Affiliated Hospital of Xinxiang Medical College and the First People's Hospital of Pingdingshan City from January 2020 to December 2021 were collected.This project has been approved by the Hospital Ethics Committee(First Affiliated Hospital of Xinxiang Medical College,No.2018036;First People's Hospital of Pingdingshan City,No.2019-018).The expression of LINC01410 in ESCC tissues was detected by real-time fluorescence quantitative polymerase chain reaction(RTFQ-PCR).We transfected EC109 cells with LV-NC or LV-over/LINC01410 and EC9706 cells with shRNA-NC or shRNA-LINC01410.Stable transfected cells(EC109/NC,EC109/OE,EC9706/NC and EC9706/KD)were selected in primary cell culture medium containing puromycin.The expression of LINC01410 was detected by RTFQ-PCR.The impact of LINC01410 on ESCC cell proliferation was determined by 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide(MTT)and colony formation assays.The effect of LINC01410 on ESCC cell invasion was detected by transwell migration assay.T cell factor/lymphoid enhancer factor 1(TCF/LEF1)luciferase reporter assay was performed to validate the effect of LINC01410 on the activity of canonical Wnt/β-catenin signaling pathway.The expressions of Wnt/β-catenin and epithelial-mesenchymal transition(EMT)signal pathway related proteins in ESCC cells were detected by Western blot.Results:By analyzing the LINC01410 expression from ESCC samples in TCGA by GEPIA2,we found LINC01410 was consistently increased in ESCC tumors compared with normal tissues(P＜0.05),and high LINC01410 expression was associated with poorer overall survival(OS).RTFQ-PCR assay showed that expressions of LINC01410 were higher in esophageal cancer tissues and esophageal cancer cells(EC109 and EC9706)than in precancerous tissues and HEEC cells(P＜0.05).The expression level of LINC01410 was significantly correlated with invasion range,lymph node metastasis and TNM stage in ESCC patients(P＜0.01).LINC01410 expression was also upregulated in EC109/OE,however the expression of LINC01410 in EC9706/KD was decreased(P＜0.01).MTT assay showed overexpression of LINC01410 increased the viability of EC109 cells,while knockdown of LINC01410 decreased the viability of EC9706 cells(P＜0.01).Colony formation assay indicated that overexpression of LINC01410 enhanced the clonogenic ability of ESCC cells,while knockdown of LINC01410 reduced colony formation(P＜0.01).Transwell migration assay showed that LINC01410 overexpression drastically increased the number of migratory cells,while silencing of LINC01410 suppressed the migration in EC9706 cells(P＜0.01).GSEA revealed that Wnt/β-catenin and EMT pathways were significantly enriched in ESCC samples with a high level of LINC01410.TCF/LEF1 luciferase reporter assay showed higher levels of Wnt-dependent activities were observed in EC109/OE cells,whereas silenced LINC01410 in EC9706 cells led to contrary results(P＜0.01).Western blot analysis showed that overexpression of LINC01410 in EC109 cell significantly increased the expression levels of N-cadherin,β-catenin,cyclin D1,c-Myc and decreased E-cadherin expression,while knockdown LINC01410 resulted in opposite results.Conclusion:LINC01410 promotes proliferation and metastasis of ESCC,which might be caused by activation of Wnt/β-catenin and EMT signaling pathways.

Objective:To investigate the efficacy and prognosis of induction therapy combined with chemotherapy and tyrosine kinase inhib-itors(TKI)in adult Philadelphia chromosome-positive acute lymphoblastic leukemia(Ph+ALL).Methods:This study retrospectively analyzed the clinical features,biological characteristics,complete remission,curative effect,and prognosis of 60 adult patients with Ph+ALL treated in GeneraI Hospital of Ningxia Medical University from January 2012 to October 2023.Results:Among the patients,43(71.67%,43/60)achieved complete remission(CR)after the first induction therapy,including 7(41.18%,7/17)in the chemotherapy-alone group and 36(83.72%,36/43)in the TKI-plus-chemotherapy group(P=0.003).The 2-year overall survival(OS)rate of patients in the chemotherapy-alone group(28.2%)was significantly less than that of patients in the TKI-plus-chemotherapy group(56%,P=0.041).In the transplant and non-transplant groups,the 2-year and 5-year OS rates were 76.9%vs.51.9%,56.1%vs.19.4%,respectively(P=0.003).The 2-year progression-free survival(PFS)rate was better in the transplant group(38.5%)than in the non-transplant group(12.1%,P=0.018).Univariate prognostic analysis showed that whether TKI was selected,whether CR was obtained after the initial induction therapy,and whether bone marrow transplantation was performed,significantly affected OS prognosis(P<0.05).The white blood cell count and whether TKI was selected signi-ficantly affected the relapse-free survival(RFS)of patients(P<0.05).Cox multivariate prognostic analysis showed that CR,after induction therapy,and subsequent hematopoietic stem cell transplantation were independent prognostic factors for OS.Conclusions:In the Ph+ALL in-duction therapy regimens,TKI-plus-chemotherapy induction therapy can achieve early remission and a high remission rate,and the OS is better than chemotherapy alone.After CR,bone marrow hematopoietic stem cell transplantation for Ph+ALL had a good prognosis.

Objective To assess the safety of femoral artery puncture procedures guided by X-ray and ultrasound among elderly patients.Methods A total of 480 patients undergoing transcatheter interventional treatment for cardiovascular and cerebrovascular diseases through the femoral ar-tery in our hospital between January 2016 and December 2022 were enrolled in the study.Of them,326 patients receiving femoral artery puncture guided by X-ray fluoroscopy were assigned into X-ray group,while the other 154 patients guided by vascular Doppler ultrasound were into ultrasound group.With propensity score matching(PSM)in a ratio of 1∶1,finally 270 patients were included.Their general clinical data,success rate of puncture,puncture site,and incidence of vascular complications were compared between the two groups.Multivariate logistic regression analysis was used to identify the risk factors for vascular complications.Results Before PSM,there were no statistical differences in the mean distance from the skin fold to the bifurcation of the common femoral artery(2.5±1.0 cm vs 2.4±0.8 cm)or the distance from the fold to the in-guinal ligament(6.4±1.4 cm vs 6.3±1.7 cm)between the X-ray group and the ultrasound group(P＞0.05).After PSM,the X-ray group exhibited an obviously higher incidence of puncture points below the common femoral artery than the ultrasound group(14.8％vs 6.7％,P＜0.05),but no significant differences were observed in the one-time success rate of puncture or the occur-rence of vascular complications between the two groups(P＞0.05).Multivariate logistic regres-sion analysis indicated that the presences of non-common femoral artery and femoral artery calci-fication at the puncture site was independent risk factors for vascular complications(OR=8.379,95％CI:3.561-19.717;OR=3.922,95％CI:1.664-9.242).Conclusion There is no statistical disparity in safety between X-ray-versus ultrasound-guided femoral artery puncture procedures.Cli-nicians should choose appropriate puncture procedure or combine them together based on individual con-dition of patients.

Objective To investigate the efficacy of utilizing Kaneka dual lumen microcatheter in combination with anchored balloon in treatment of bifurcation lesions in elderly patients with ra-dial artery 6 F catheter.Methods A retrospective analysis was performed on 168 patients(≥60 years)receiving bifurcation treatment with a 6 F catheter via the radial artery at the Heart Center of our hospital from January 2020 to January 2023.According to application of dual lumen micro-catheters and anchoring balloon technology or not,they were assigned into an anchoring group(81 cases old)and a control group(87 cases).A comparison was made between the two groups in terms of features of coronary artery disease,operation procedure,and MACE.Multivariate logistic regression analysis was employed.Results Lower incidence of dissection,shorter operation time,less X-ray exposure dose,and decreased contrast agent dosage were observed in the anchoring group when compared with the control group(P＜0.05,P＜0.01).There was no statistical differ-ence in the MACE incidence between the two groups(4.9％vs 8.0％,P＞0.05).The side branch dissection and final TIMI grade＜3 of side branch flow were independent risk factors for postop-erative MACE in elderly patients with bifurcation lesions after surgery(P＜0.05,P＜0.01).Conclusion Kaneka dual lumen microcatheter combined with anchored balloon technology via radial artery 6 F catheter has the advantages in effectively shorting operation time,minimizing X-ray exposure,reducing contrast agent usage,and diminishing the incidence of side branch dis-section in treatment of bifurcation lesions in elderly patients undergoing surgical treatment.

Objective To explore the difference in efficacy of metoprolol versus ivabradine in the treatment of postural orthostatic tachycardia syndrome(POTS)in the elderly after COVID-19 infection.Methods A total of 110 patients diagnosed with POTS at our department from Decem-ber 1,2022 to January 31,2023 were included.According to their drug regimen,they were divided into metoprolol group(62 patients)and ivabradine group(48 patients).On the 28th day of out-patient follow-up,the resting heart rate,heart rate of 10 min of standing,symptom disappearance rate,hospitalization rate,and mortality rate were compared between the two groups.Results On the 28th day of treatment,the resting heart rate and postural heart rate for 10 min were decreased in both groups when compared with the levels at initial diagnosis(P＜0.01).And there were no significant differences in the two types of heart rate between the two groups on the 28th day(71.0±7.0 vs 72.1±7.0,P=0.401;76.5±7.2 vs 77.4±7.6,P=0.573).No obvious differences were observed between the two groups in symptom disappearance rate,hospitalization rate,or mortality rate(88.7％vs 89.6％,3.2％vs2.1％,0％vs 0％,P＞0.05).Conclusion Metoprolol and ivabradine can effectively treat POTS in the elderly patients after COVID-19 infection.

Purpose: This study aimed to confirm the joint association of hard of hearing and handgrip strength with falls among Koreans aged 65 years and above. Methods: This cross-sectional study was based on the 2020 Korean Longitudinal Study of Aging data and included 4,372 participants who completed a falls-related questionnaire. Grip strength was measured, and hearing status was self-reported. Multivariate logistic regression assessed associations between hearing status, handgrip strength, and falls. Analyses were adjusted for variables such as age, sex, body mass index, education level, and medical history. Results: The study found a significant association between being hard of hearing and increased odds of falls (odds ratio [OR], 2.73; 95% confidence interval [CI], 1.56–4.78). Additionally, individuals with low handgrip strength had higher odds of falls (OR, 1.70; 95% CI, 0.88–3.31) than those with normal handgrip strength. Among individualswho were hard of hearing, the group with normal handgrip strength showed 28% lower odds of falls (OR, 0.72; 95% CI, 0.18–2.87), although this result did not reach statistical significance. Conclusion These findings highlight the high fall odds associated with being hard of hearing and suggest that handgrip strength may have a potential protective effect in individuals aged 65 years and older. Our study contributes to an increased understanding of risk factors for falls in older adults and emphasizes the need to address sensory impairment and muscle strength in prevention efforts. Future studies must validate and extend these findings to improve quality of life and reduce fall-related injuries in older adults.

Objective:To evaluate the efficacy and safety of Osimertinib in the second-line and above treatment of elderly patients with advanced lung adenocarcinoma with epidermal grouth factor receptor(EGFR)mutation.Methods:A retrospective analysis of 51 elderly patients with advanced lung adenocarcinoma aged 65 years and over was performed.EGFR gene mutations were detected at baseline.The patients were treated with Osimertinib as second or later-line treatment after disease progression on prior epidermal growth factor receptor tyrosine kinase inhibitor(EGFR-TKI)therapy.Results:The median age of the patients was 72 years old, and the median progression-free survival(PFS)with Osimertinib was 13 months(95% CI: 10.8-15.2 months). Patients with exon 19 deletion(19del)treated with Osimertinib had longer PFS than patients with EGFR 21 exon L858R mutation(12 vs.24 month, P=0.028). In patients with EGFR resistance mutation T790M(T790M-positive), the PFS of patients with 19del combined with T790M(19del / T790M-positive)was better than that of patients with L858R combined with T790M(L858R / T790M-positive)(10 vs.28 months, P=0.029). After Osimertinib treatment, 43.8% of patients had brain or meningeal progression.The most commonly used agents for treatment after resistance to Osimertinib are antiangiogenic drugs.The common adverse reactions of Osimertinib were diarrhea(31.4 %), followed by dry skin with itching(29.4%)and rash(25.5 %). Most adverse reactions were grade 1 to 2, and one patient discontinued the drug intermittently due to grade 3 hematological adverse reactions. Conclusions:Osimertinib is effective and well tolerated in elderly patients with advanced EGFR-mutant lung adenocarcinoma.

Objectives:To investigate the potential classification of quality of life in HIV-infected men who have sex with men (HIV-infected MSM) and to analyze possible influencing factors of different categories.Methods:A questionnaire survey was conducted among HIV-infected MSM who received antiretroviral treatment (ART) in an infectious disease hospital in Ji'nan, Shandong Province from October to December 2020. The quality of life scores in six domains were analyzed by latent profile analysis (LPA), and possible related factors of potential classification were explored by ordinal logistic regression analysis.Results:A total of 584 HIV-infected MSM were included in this study. LPA divided their quality of life into three categories, named low score, medium score and high score groups, accounting for 34.4% (201/584), 49.8% (291/584), and 15.8% (92/584), respectively. Multivariate ordinal logistic regression analysis showed that age above 40 years (a OR=1.77, 95% CI:1.11-2.80), monthly average income of 3 000 Yuan and below (a OR=3.15, 95% CI:1.72-5.76), monthly average income of 3 001-5 000 Yuan (a OR=2.26, 95% CI:1.41-3.62), distance to the hospital to receive drugs farer than 40 kms (a OR=1.76, 95% CI:1.07-2.89), and adverse reactions after taking drugs (a OR=2.31, 95% CI:1.65-3.23) were factors associated with low level of quality of life. Conclusions:The qualities of life of HIV-infected MSM showed group heterogeneity and were at high levels. Attention should be focused on HIV-infected MSM who are at older age, with low income, and long distance to access the health facilities. The measures should be taken to reduce the adverse reactions of ART drugs and improve the quality of life.
