OBJECTIVES: To investigate the clinical characteristics and prognosis of chronic disseminated candidiasis (CDC) in children with acute leukemia (AL) following chemotherapy. METHODS: A retrospective analysis was conducted on children diagnosed with CDC (including confirmed, clinically diagnosed, and suspected cases) after AL chemotherapy from January 2015 to December 2023 at Fujian Medical University Union Hospital, Zhangzhou Municipal Hospital, and Quanzhou First Hospital Affiliated to Fujian Medical University. Clinical characteristics and prognosis were analyzed. RESULTS: The incidence of CDC in children with AL following chemotherapy was 1.92% (32/1 668). Among the children with acute lymphoblastic leukemia, the incidence of CDC in the high-risk group was significantly higher than in the low-risk group (P=0.002). All patients presented with fever unresponsive to antibiotics during the neutropenic period, with 81% (26/32) involving the liver. C-reactive protein (CRP) levels were significantly elevated (≥50 mg/L) in 97% (31/32) of the patients. The efficacy of combined therapy with liposomal amphotericin B and caspofungin or posaconazole for CDC was 66% (19/29), higher than with caspofungin (9%, 2/22) or liposomal amphotericin B (18%, 2/11) monotherapy. The overall cure rate was 72% (23/32). The proportion of patients with CRP ≥50 mg/L and/or a positive β-D-glucan test for more than 2 weeks and breakthrough infections during caspofungin treatment was significantly higher in the treatment failure group compared to the successful treatment group (P<0.05). CONCLUSIONS CDC in children with AL after chemotherapy may be associated with prolonged neutropenia due to intensive chemotherapy. Combination antifungal regimens based on liposomal amphotericin B have a higher cure rate, while persistently high CRP levels and positive β-D-glucan tests may indicate poor prognosis.

BACKGROUND: It is inaccurate to reflect the level of dust exposure through working years. Furthermore, identifying a predictive indicator for lung function decline is significant for coal miners. The study aimed to explored whether club cell secretory protein (CC16) levels can reflect early lung function changes. METHODS: The cumulative respiratory dust exposure (CDE) levels of 1,461 coal miners were retrospectively assessed by constructed a job-exposure matrix to replace working years. Important factors affecting lung function and CC16 were selected by establishing random forest models. Subsequently, the potential of CC16 to reflect lung injury was explored from multiple perspectives. First, restricted cubic spline (RCS) models were used to compare the trends of changes in lung function indicators and plasma CC16 levels after dust exposure. Then mediating analysis was performed to investigate the role of CC16 in the association between dust exposure and lung function decline. Finally, the association between baseline CC16 levels and follow-up lung function was explored. RESULTS: The median CDE were 35.13 mg/m³-years. RCS models revealed a rapid decline in forced vital capacity (FVC), forced expiratory volume in the first second (FEV₁), and their percentages of predicted values when CDE exceeded 25 mg/m³-years. The dust exposure level (<5 mg/m³-years) causing significant changes in CC16 was much lower than the level (25 mg/m³-years) that caused changes in lung function indicators. CC16 mediated 11.1% to 26.0% of dust-related lung function decline. Additionally, workers with low baseline CC16 levels experienced greater reductions in lung function in the future. CONCLUSIONS CC16 levels are more sensitive than lung indicators in reflecting early lung function injury and plays mediating role in lung function decline induced by dust exposure. Low baseline CC16 levels predict poor future lung function.

Atrial fibrillation (AF) is the most common arrhythmia in clinical practice. It has a high prevalence and poor prognosis. The application of antiarrhythmic drugs and even surgery cannot completely treat the disease, and there are many sequelae. AF can be classified into the category of "palpitation" in Chinese medicine according to its symptoms. Acupuncture has a significant effect on AF. The authors find that an important mechanism of acupuncture in AF treatment is to regulate the cardiac vagus nerve. Therefore, this article intends to review the distribution and function of vagus nerve in the heart, the application and the regulatroy effect for the treatment of AF.

OBJECTIVE: To evaluate the dynamic changes of glucocorticoid (GC) dose and the feasibility of GC discontinuation in rheumatoid arthritis (RA) patients under the background of Chinese medicine (CM). METHODS: This multicenter retrospective cohort study included 1,196 RA patients enrolled in the China Rheumatoid Arthritis Registry of Patients with Chinese Medicine (CERTAIN) from September 1, 2019 to December 4, 2023, who initiated GC therapy. Participants were divided into the Western medicine (WM) and integrative medicine (IM, combination of CM and WM) groups based on medication regimen. Follow-up was performed at least every 3 months to assess dynamic changes in GC dose. Changes in GC dose were analyzed by generalized estimator equation, the probability of GC discontinuation was assessed using Kaplan-Meier curve, and predictors of GC discontinuation were analyzed by Cox regression. Patients with <12 months of follow-up were excluded for the sensitivity analysis. RESULTS: Among 1,196 patients (85.4% female; median age 56.4 years), 880 (73.6%) received IM. Over a median 12-month follow-up, 34.3% (410 cases) discontinued GC, with significantly higher rates in the IM group (40.8% vs. 16.1% in WM; P<0.05). GC dose declined progressively, with IM patients demonstrating faster reductions (median 3.75 mg vs. 5.00 mg in WM at 12 months; P<0.05). Multivariate Cox analysis identified age <60 years [P<0.001, hazard ratios (HR)=2.142, 95% confidence interval (CI): 1.523-3.012], IM therapy (P=0.001, HR=2.175, 95% CI: 1.369-3.456), baseline GC dose ⩽7.5 mg (P=0.003, HR=1.637, 95% CI: 1.177-2.275), and absence of non-steroidal anti-inflammatory drugs use (P=0.001, HR=2.546, 95% CI: 1.432-4.527) as significant predictors of GC discontinuation. Sensitivity analysis (545 cases) confirmed these findings. CONCLUSIONS RA patients receiving CM face difficulties in following guideline-recommended GC discontinuation protocols. IM can promote GC discontinuation and is a promising strategy to reduce GC dependency in RA management. (Trial registration: ClinicalTrials.gov, No. NCT05219214).

Hepatic stellate cells (HSCs) are the primary fibrogenic cells in the liver, and their activation plays a crucial role in the development and progression of hepatic fibrosis. Here, we report that retinoid X receptor-alpha (RXRα), a unique member of the nuclear receptor superfamily, is a key modulator of HSC activation and liver fibrosis. RXRα exerts its effects by modulating calcium/calmodulin-dependent protein kinase kinase β (CaMKKβ)-mediated activation of AMP-activated protein kinase-alpha (AMPKα). In addition, we demonstrate that K-80003, which binds RXRα by a unique mechanism, effectively suppresses HSC activation, proliferation, and migration, thereby inhibiting liver fibrosis in the CCl₄ and amylin liver NASH (AMLN) diet animal models. The effect is mediated by AMPKα activation, promoting mitophagy in HSCs. Mechanistically, K-80003 activates AMPKα by inducing RXRα to form condensates with CaMKKβ and AMPKα via a two-phase process. The formation of RXRα condensates is driven by its N-terminal intrinsic disorder region and requires phosphorylation by CaMKKβ. Our results reveal a crucial role of RXRα in liver fibrosis regulation through modulating mitochondrial activities in HSCs. Furthermore, they suggest that K-80003 and related RXRα modulators hold promise as therapeutic agents for fibrosis-related diseases.

Objective:To observe the clinical efficacy and safety of Tongren Niuhuang Qingxin Pills combined with telmisartan tablets in the treatment of hypertensive vertigo syndrome of phlegm-heat disturbance.Methods:Randomized controlled trial was conducted. Totally 80 patients with hypertension vertigo and phlegm-heat disturbance syndrome were selected from March 2021 to August 2022 at Beijing Tongrentang Hospital of Traditional Chinese Medicine as the observation objects. They were randomly divided into two groups using a random number table method, with 40 cases in each group. The control group received oral telmisartan tablets, while the experimental group received Tongren Niuhuang Qingxin Pills in addition to the control group. Both groups were treated for 28 days and followed up for 1 month. The patients' room blood pressure before and after treatment was measured, and TCM syndrome scores were evaluated. The dizziness assessment rating scale (DARS) was used to evaluate the severity of dizziness, adverse reactions during treatment were recorded, drug safety was observed, and clinical efficacy was evaluated.Results:The total effective rate of the experimental group was 85.0% (34/40), and that of the control group was 7.5% (3/40), with statistical significance between the two groups ( χ2=48.32, P<0.001). Compared with before treatment, the experimental group had SBP [(136.63 ± 6.01) mmHg vs. (159.30 ± 9.01) mmHg, t=-21.00] and DBP [(84.48 ± 4.36) mmHg vs. (95.30 ± 3.75) mmHg, t=-13.80] after treatment; after treatment, SBP [(137.34 ± 6.39) mmHg vs. (158.00 ± 10.06) mmHg, t=-5.28] and DBP [(86.08 ± 4.43) mmHg vs. (95.18 ± 6.61) mmHg, t=-8.09] decreased in the control group ( P<0.01), but there was no statistical significance between the two groups after treatment ( P>0.05). After treatment, the TCM syndrome scores in the experimental group (8.68 ± 3.39 vs. 15.12 ± 3.03, Z=-6.61) were lower than those in the control group ( P<0.001), and DARS score [(8.53 ± 3.93) vs. (12.20 ± 3.95), Z=-3.63] was lower than that in the control group ( P<0.001). After treatment, the therapeutic effect index of TCM syndromes in the experimental group improved compared to before treatment in the same group. The therapeutic effect index of each symptom, from high to low, was as follows: rotation of oneself or visual objects>numbness of limbs>dry stool>dizziness and dizziness>liking cold drinks>bitter and dry mouth>red urine>red tongue, yellow coating, and greasy tongue>vomiting sticky and turbid phlegm>tinnitus>smooth pulse. There were no significant adverse reactions during the treatment of the two groups. Conclusion:Tongren Niuhuang Qingxin Pills combined with telmisartan can reduce the blood pressure of patients with hypertensive vertigo syndrome of phlegm-heat disturbance, improve the vertigo symptoms and TCM syndromes of patients, and the efficacy evaluation is superior to that of telmisartan alone.

Osteonecrosis of the femoral head(ONFH)is a common orthopedic disease,and hip preservation surgery has high clinical value in the early stages of ONFH,especially for young and middle-aged patients.However,the repair of ONFH is heterogeneous,leading to inter-individual variations in the efficacy of hip preservation.Currently,the existing tissue-engineered scaffolds in the field of hip preservation are uncontrollable after implantation,making it difficult to achieve precise repair.Smart responsive materials have good biocompatibility and self-feedback capability.By combining them with therapeutic drugs to construct stimulus-responsive drug delivery systems,new possibilities are provided for the precise repair of ONFH.This paper reviews the research progress of smart responsive materials at home and abroad.Based on the response principles of various materials and the repair characteristics of ONFH,the application prospects of various smart responsive materials such as reactive oxygen species-responsive,fluid shear stress-responsive,and light/magnetic-responsive materials are discussed and prospected in the field of precise repair for ONFH,providing new ideas for the precise treatment of ONFH.

Hemophagocytic syndrome(HPS),also known as hemophagocytic lymphohistiocytosis(HLH),is a rare and highly malignant hematologic disease with a poor prognosis.It can be divided into two categories:primary HLH and secondary HLH.HLH is characterized by a large number of abnormal immune cells that continuously activate and regulate out of control,leading to systemic inflammatory factor storm and multiple organ failure.Clinical manifestations mainly include persistent malignant hyperthermia,pancytopenia,hepatosplenomegaly,and hemophagocytosis in tissues and organs.The pathogenesis of adult HLH is complex,with rapid onset and rapid disease progression,and the fatality rate remains high.The main causes of death in HLH patients are multiple organ failure,abnormal coagulation and septic shock.Due to the specificity of HLH and the lack of effective understanding of the severity and prognosis in clinical practice,some HLH patients are misdiagnosed or overlooked,missing the best opportunity for diagnosis and treatment.Therefore,this review systematically explores and discusses the latest diagnostic and treatment progress of adult HLH,aiming to provide reference for clinical diagnosis,treatment and prognosis assessment of HLH.

Primary intestinal diffuse large B-cell lymphoma(PI-DLBCL)is clinically rare,but in recent years,with the gradual maturity of pathology and molecular biology technology,its incidence rate and diagnosis rate have also increased.Due to the lack of specificity of the clinical symptoms of PI-DLBCL,it is easy to misdiagnose and miss the diagnosis,and there is no consensus on the best treatment of PI-DLBCL in clinical practice.Therefore,by retrieving the latest literature at home and abroad,this review systematically discusses the pathogenesis,clinical manifestations,diagnostic criteria,treatment and prognosis of PI-DLBCL,in order to improve the understanding of rare PI-DLBCL in hematology and oncology,and provide reference for basic research and clinical diagnosis and treatment of PI-DLBCL.

Objective:To explore and analyze the clinical features and prognostic factors of secondary intestinal diffuse large B-cell lymphoma(SI-DLBCL),in order to provide reference for the basic research and clinical diagnosis and treatment of secondary lymphoma of rare sites in the field of hematology.Methods:The clinical data of 138 patients with SI-DLBCL admitted to Fujian Medical University Union Hospital from June 2011 to June 2022 were collected and sorted,the clinical and pathological features,diagnosis,treatment and prognosis were analyzed.Cox regression risk model was used to conduct univariate and multivariate analysis on the prognostic risk factors.Results:Among the 138 patients with SI-DLBCL included in this study,85(61.59％)were male,53(38.41％)were female,the median age of onset was 59.5(16-84)years,the clinical manifestations lacked specificity,the first-line treatment regimen was mainly chemotherapy(67.39％),94 cases(68.12％)received chemotherapy alone,40 cases(28.98％)were treated with chemotherapy combined with surgery,and 4 cases(2.90％)were treated with surgery alone.The median follow-up time was 72(1-148)months.Among the 138 patients with SI-DLBCL,79(57.25％)survived,34(24.64％)died,25 cases(18.12％)lost to follow-up,the PFS rates of 1-year,3-year and 5-year were 57.97％,49.28％and 32.61％,and the OS rates of 1-year,3-year and 5-year were 60.14％,54.35％and 34.06％,respectively.The results of univariate Cox regression analysis showed that age,Lugano stage and IPI score were the influencing factors of OS in SI-DLBCL patients,and age,Lugano stage and IPI score were the influencing factors of PFS in SI-DLBCL patients.The results of multivariate Cox analysis showed that Lugano stage was an independent prognostic factor affecting OS and PFS in SI-DLBCL patients.Conclusion:Patients with SI-DLBCL are more common in middle-aged and elderly men,and the early clinical manifestations lack specificity,and the first-line treatment regimen is mainly R-CHOP chemotherapy,and Lugano stage is an independent prognostic factor affecting OS and PFS in SI-DLBCL patients.
