Objective:To investigate the clinical features and prognostic factors of newly-treated elderly acute myeloid leukemia (AML) patients with intermediate-risk karyotype.Methods:A retrospective case series study was conducted. A total of 87 newly-treated elderly AML patients with intermediate-risk karyotype in the First Affiliated Hospital of University of Science and Technology of China (Anhui Provincial Hospital) from January 2013 to December 2023 were selected. The clinical characteristics were summarized. The Kaplan-Meier method was used for survival analysis and Cox proportional hazards model was used to make univariate and multivariate analyses of prognostic factors.Results:The median age [ M ( Q1, Q3)] of 87 patients was 69 (60, 87) years. The patients with normal karyotype and abnormal karyotype accounted for 77.1% (67/87), 22.9% (20/87), respectively. A total of 74 patients (85.1%) had 1 or more gene mutations, of which FLT3-ITD, NPM1 mutation, CEBPA mutation and WT1 high expression accounted for 29.9% (26/87), 26.4% (23/87), 19.5% (17/87), and 65.5% (57/87), respectively; additionally, 44.7% (39/87) of patients had 2 or more gene mutations. The objective response rate of patients after induction therapy was 47.7% (41/87), while the relapse rate was 73.2% (30/41). The median progression-free survival (PFS) time was 7.8 months, and the median overall survival (OS) time was 12.1 months. Univariate analysis result revealed that age, FLT3-ITD, hypomethylating agents, and minimal residual disease complete remission (MDR-CR) were factors influencing the OS of newly-treated elderly AML patients with intermediate-risk karyotype (all P < 0.05). Multivariate analysis indicated that MDR-CR was an independent risk factor for OS (yes vs. no: HR = 0.27, 95% CI: 0.14-0.51, P < 0.001). Conclusions:Newly-treated elderly AML patients with intermediate-risk karyotype have a high relapse rate and poor prognosis, and MDR-CR is identified as an independent influencing factor for the prognosis of these patients.

OBJECTIVE To investigate the effects of the split formulas of Biyuan Heji(BYHJ)on paranasal sinus mucosal in-flammation in rats with acute rhinosinusitis(ARS)based on the pathogenesis of"wind-cold transforming into lung-heat".METHODS Unilateral nasal cavity occlusion combined with nasal dripping of Staphylococcus aureus were performed to establish a rat model of ARS.SD rats were randomly divided into blank,model,BYHJ(wind-cold removal+lung-heat removal),lung-heat removal,wind-cold removal,and positive drug groups,with 6 rats in each group.The rats were treated with the corresponding drugs for 7 d and then the samples were collected.HE staining was used to observe the pathological changes of rat paranasal sinus mucosa tissues,ELISA was employed to determine the levels of interleukin-1β(IL-1β),IL-6,IL-8,IL-9,IL-10,and IL-12 in serum,immunohistochemis-try(IHC)was adopted to measure the protein expression of tumor necrosis factor-α(TNF-α)and intercellular adhesion molecule(ICAM-1)in paranasal sinus mucosa tissues,and Western blot was used to detect the protein expression of phosphorylated p38 mito-gen-activated protein kinase(p38 MAPK),nuclear transcription factor-κB p50(NF-κB p50),and NF-κB p65 in paranasal sinus mucosa tissues.RESULTS The acute sinusitis rat inflammation model was successfully established.Compared with the model group,the water drinking,diet eating,and body weight of rats in the BYHJ group,wind-cold removal,lung-heat removal,and positive drug groups were significantly improved,the aggregation of inflammatory cells in the paranasal sinus mucosal tissue was reduced,and the levels of IL-1β,IL-6,IL-8,IL-9,and IL-12 in the serum were significantly reduced(P<0.01),IL-10 content significantly in-creased(P<0.01),the protein expression of TNF-α,ICAM-1,p38 MAPK,NF-κB p50,and NF-κB p65 in the paranasal sinus mucosa was significantly decreased(P<0.01).The comparison between various traditional Chinese medicine groups showed that the decrease of IL-1β,IL-6,IL-8,IL-9,IL-12,TNF-α,ICAM-1,p38 MAPK,NF-κB p50,and NF-κB p65 and the increase of IL-10 in the BYHJ group were better than those in the split formula groups(P<0.01),and the lung-heat removal group was better than the wind-cold removal group(P<0.01).CONCLUSION BYHJ and its split formulas can effectively inhibit the inflammatory response in rats with ARS.

OBJECTIVE To explore the clinical efficacy and possible mechanism of the classic prescription Xinyi Powder in the treatment of allergic rhinitis with lung deficiency related cold.METHODS A total of 189 patients who met the inclusion criteria of al-lergic rhinitis with lung deficiency related cold in the otolaryngology clinic of Jiangsu Province Hospital of Chinese Medicine from Janu-ary 2023 to July 2024 were selected and randomly divided into the experimental group(n=126)and the control group(n=63).The control group was treated with oral loratadine,and the experimental group took Xinyi Powder.Before and after treatment,the TNSS,TNNSS scores and TCM syndrome scores of the two groups of patients were compared to comprehensively evaluate the clinical efficacy.The changes in the patients'quality of life were evaluated in multiple dimensions using nasal VAS and RQLQ scores.The changes in serum IL-4,IL-5,IgE,SP and CGRP expression levels were detected by ELISA.RESULTS After 14 days of treatment,the TNSS,TNNSS,VAS,RQLQ scores and TCM syndrome scores of the two groups of patients were reduced(P<0.01);the experi-mental group was better than the control group in improving the concomitant symptoms such as nasal congestion,runny nose,postnasal drip,and itchy eyes(P<0.05,P<0.01),and it could also significantly improve the symptoms of fear of wind and cold,spontaneous sweating,shortness of breath,and cough with thin sputum(P<0.01),and the total RQLQ score was significantly better than the con-trol group(P<0.01).After treatment,the serum IL-4,IL-5,IgE,SP,and CGRP levels of the two groups of patients were signifi-cantly reduced(P<0.01),and there was no statistical difference between the two groups.CONCLUSION Xinyi Powder can signifi-cantly alleviate the nasal symptoms and systemic concomitant symptoms of patients with allergic rhinitis of lung deficiency and cold type,and significantly improve the quality of life of patients.It may play a therapeutic role by inhibiting the expression of inflammatory factors and neuropeptides and regulating neuroimmunity.

Dry eye disease (DED) is a prevalent and intractable ocular disease induced by a variety of causes. Elevated sphingomyelin (SM) levels and pro-inflammatory cytokines were detected on the ocular surface of DED patients, particularly in the meibomian glands. Sphingomyelin synthase 2 (SMS2), one of the proteins involved in SM synthesis, would light a novel way of developing a DED therapy strategy. Herein, we report the design and optimization of a series of novel thiophene carboxamide derivatives to afford 14l with an improved highly potent inhibitory activity on SM synthesis (IC_{50, SMS2} = 28 nmol/L). Moreover, 14l exhibited a notable protective effect of anti-inflammation and anti-apoptosis on human corneal epithelial cells (HCEC) under TNF-α-hyperosmotic stress conditions in vitro, with an acceptable ocular specific distribution (corneas and meibomian glands) and pharmacokinetics (PK) profiles (t _{1/2, cornea} = 1.11 h; t _{1/2, meibomian glands} = 4.32 h) in rats. Furthermore, 14l alleviated the dry eye symptoms including corneal fluorescein staining scores and tear secretion in a dose-dependent manner in mice. Mechanically, 14l reduced the mRNA expression of Tnf-α, Il-1β and Mmp-9 in corneas, as well as the proportion of very long chain SM in meibomian glands. Our findings provide a new strategy for DED therapy based on selective SMS2 inhibitors.
