Atopic dermatitis （AD） is an atopic disease with a complex etiology and pathogenesis resulting from the interaction of multiple factors. The NOD-like receptor pyrin domain-containing 3 （NLRP3） inflammasome is an important component of innate immunity and is involved in the onset and progression of AD， encompassing multiple processes such as inflammation， pyroptosis， and autophagy. Traditional Chinese medicine （TCM） has shown significant clinical efficacy in the treatment of AD and also offers advantages including flexible compatibility， multi-target effects， and low drug resistance. A large number of studies have shown that single Chinese medicinal components and compound prescriptions can treat atopic diseases by modulating the NLRP3 inflammasome. This article elaborates on the activation of the NLRP3 inflammasome and its influence on the pathogenesis and progression of AD， and summarizes recent studies on the mechanisms by which active constituents， extracts， and compound formulations of Chinese medicine treat AD through regulation of the NLRP3 inflammasome and related signaling pathways， with the aim of providing a reference for the clinical treatment of AD and the development of TCM.

Objective:To investigate the clinical features and prognostic factors of pediatric patients with acute hyperleukocytic leukemia (AHL).Methods:A retrospective case series study was conducted. The clinical data of 99 pediatric patients diagnosed with AHL who admitted to the Affiliated Huai'an No.1 People's Hospital of Nanjing Medical University between May 2015 and November 2020 were retrospectively analyzed. The enrolled children were grouped based on the following factors including gender, age, initial white blood cell count (WBC), initial lactate dehydrogenase (LDH), whether tumor lysis syndrome (TLS) occurred, immunophenotype, fusion gene, whether complete remission (CR) was achieved on the 19th day (D19) after transplantation, and whether CR was achieved on the 46th day (D46) after transplantation. All the patients were treated with the chemotherapy regimen of Shanghai Children's Medical Center - Acute Lymphoblastic Leukemia - 2015 (SCMC-ALL-2015). Flow cytometry was used to monitor the minimal residual disease (MRD); fluorescence in situ hybridization (FISH) was used to screen out the mutant genes. The median follow-up time was 47 months. The Kaplan-Meier method was used for survival analysis, and the log-rank test was used for intergroup comparisons. Multivariate Cox proportional hazard regression model was used to screen out the the prognostic factors.Results:Among 99 AHL patients, there were 65 males and 35 females; the median age was 7.71 (3.32, 11.20) years. At the initial diagnosis, 48 cases had WBC≤100×10 9/L, and 51 cases had WBC>100×10 9/L; 36 cases had LDH ≤ 2 000 U/L, and 63 cases had LDH > 2 000 U/L; 3 cases had TLS, 5 cases had MLL::AF4 positive, 7 cases had BCR::ABL positive, 7 cases had E2APBX1 positive, and 10 cases had TEL::AML1 positive; 28 cases were acute T-cell lymphoblastic leukemia (T-ALL), and 71 cases were acute B-cell lymphoblastic leukemia (B-ALL). At D19, 74 cases achieved bone marrow CR; at D46, 82 cases achieved bone marrow CR; 3-year and 5-year OS rates were 74.5% and 71.3%, respectively. During the follow-up, 14 cases relapsed and 15 died, including 12 dying of relapse, 2 dying of infection and 1 case dying of pulmonary graft-versus-host disease (GVHD). There were statistically significant differences in the 3-year OS rate in patients with different age, initial WBC, initial LDH, immunophenotyping, whether bone marrow CR at D19 was achieved, whether MRD at D19 occurred, whether bone marrow CR at D46 was achieved, whether MRD at D46 occurred, the presence of TLS, MLL::AF4 positive and TEL::AML1 positive (all P < 0.05). Furthermore, multivariate Cox regression analysis showed that LDH(>2 000 U/L), MLL::AF4 positive, T immunophenotyping, relapse, not achieving bone marrow CR at D19, not achieving bone marrow CR at D46, and MRD positive at D46 were independent risk factors influencing 3-year OS rate (all P < 0.05). Conclusions:Pediatric patients with AHL have high tumor burden at early stage, and TLS may cause death. Patients treated with the SCMC-ALL-2015 protocol can achieve favorable therapeutic effects and prognosis. LDH, MLL::AF4, immunophenotyping and relapse are prognostic factors.

BACKGROUND: The proportion of patients with non-small cell lung cancer (NSCLC) harboring epidermal growth factor receptor (EGFR) mutations is relatively high in China. However, these patients currently lack significant benefits from available neoadjuvant treatment options. This study aims to explore the potential application value of neoadjuvant targeted therapy by evaluating its efficacy and safety in patients with EGFR-mutant resectable lung adenocarcinoma. METHODS: A multicenter retrospective study was used to analyze the treatment effect of patients with stage IIA-IIIB EGFR-mutant lung adenocarcinoma who underwent surgical resection after receiving neoadjuvant targeted therapy from July 2019 to October 2024. RESULTS: A total of 24 patients with EGFR-mutant lung adenocarcinoma from three centers were included in this study. All patients successfully underwent surgery and achieved R0 resection of 100.0%. The objective response rate (ORR) was 83.3% (20/24) . The major pathologic response (MPR) rate was 37.5% (9/24), with 2 patients (8.3%) achieving pathological complete response (pCR). During neoadjuvant therapy, 13 out of 24 patients (54.2%) experienced adverse events of grade 1-2, with no occurrences of ≥ grade 3. The most common treatment-related adverse events were rash (n=4, 16.7%), mouth sores (n=2, 8.3%), and diarrhea (n=2, 8.3%). The median follow-up time was 33.0 months, no deaths occurred in all patients, and the overall survival (OS) rate was 100.0%. The 1-year disease-free survival (DFS) rate was 91.1%, and the 2-year DFS rate remained at 86.2%. CONCLUSIONS The application of neoadjuvant targeted therapy in patients with EGFR-mutant resectable lung adenocarcinoma is safe and feasible, and is expected to become a highly promising neoadjuvant treatment option for the patients with EGFR-mutant lung adenocarcinoma.

BACKGROUND:Successful uterine spiral artery remodeling is necessary for normal pregnancy,in which vascular smooth muscle cells are important cells.Interferon-γ is associated with the loss of vascular smooth muscle cells during early pregnancy.However,the specific mechanism is not fully understood. OBJECTIVE:To investigate the effects of interferon-γ on migration and apoptosis of vascular smooth muscle cells through NLRP3/caspase-1/GSDMD pyroptosis pathway. METHODS:Human vascular smooth muscle cells were divided into control group and interferon-γ group.The control group was cultured normally,and the interferon-γ group was treated with 10 ng/mL interferon-γ for 24 hours.The migration ability of vascular smooth muscle cells was detected by Transwell assay.The apoptosis of vascular smooth muscle cells was detected by TUNEL assay and flow cytometry.The mRNA expression levels of NLRP3 and caspase-1 were detected by qPCR.Western blot assay was utilized to detect NLRP3,caspase-1,and cleaved N-terminal GSDMD protein expression levels. RESULTS AND CONCLUSION:Compared with the control group,the migration ability and apoptosis rate of vascular smooth muscle cells in interferon-γ group were significantly increased(P<0.05).Compared with the control group,the mRNA expression levels of NLRP3 and caspase-1 in vascular smooth muscle cells of interferon-γ group were significantly increased(P<0.05).Compared with control group,the expression levels of NLRP3,caspase-1,and cleaved N-terminal GSDMD protein in vascular smooth muscle cells in the interferon-γ group were significantly increased(P<0.05).The results suggest that interferon-γ may regulate the migration and apoptosis of vascular smooth muscle cells through NLRP3/caspase-1/GSDMD pyroptosis pathway.

Objective To evaluate the characteristics of preoperative corneal astigmatism in cataract surgery candi-dates with high myopia.Methods In this observational study,medical records of consecutive patients who underwent cataract surgery in our hospital between January 2014 and December 2023 were reviewed retrospectively.Biometric param-eters of eyes were measured preoperatively by IOL-Master optical biometry.The cataract patients were classified into a high myopia group[defined as axial length(AL)≥26.00 mm]and a control group(normal ALs,22.00 mm ≤ AL ≤25.00 mm).The characteristics of corneal astigmatism were compared between the two groups.Results Among 17 325 cataract pa-tients(17 325 eyes),2 206 patients(2 206 eyes)had high myopia and 13 429 patients(13 429 eyes)had no high myopia.In the high myopia group,1 822 eyes(82.6％)had corneal astigmatism ≥0.50 D,1 138 eyes(51.6％)had corneal astig-matism ≥1.00 D,623 eyes(28.2％)had corneal astigmatism ≥1.50 D and 314 eyes(14.2％)had corneal astigmatism ≥2.00 D.These proportions were significantly higher than those in the control group(71.9％,35.9％,15.9％and 7.3％,re-spectively;all P＜0.001).In the high myopia group,1 340 eyes(60.7％)had moderate astigmatism,147 eyes(6.7％)had high astigmatism and 922 eyes(41.8％)had with-the-rule(WTR)astigmatism.These 3 proportions were all significantly higher than those in the control group(48.9％,3.3％and 28.2％,respectively;all P＜0.001).Among high-myopia pa-tients,the corneal astigmatism was statistically greater in women than that in men(P=0.001),and the proportion of ob-lique astigmatism was higher in women than that in men(19.3％vs.15.8％,P=0.034).The proportion of against-the-rule(ATR)astigmatism increased significantly with age.In the high myopia group,the corneal astigmatism of eyes with WTR,ATR and oblique astigmatism was(1.26±0.85)D,(1.28±0.81)D and(0.89±0.71)D,respectively.They were signifi-cantly greater than those in the control group[(0.82±0.71)D,(1.06±0.68)D and(0.67±0.53)D,respectively;all P＜0.001].In the high myopia group,there were 31.8％,12.3％and 4.1％of eyes with corneal astigmatism ≥1.00 D,≥1.50 D and ≥2.00 D,respectively.All of these 3 proportions were significantly lower than those of eyes with WTR or ATR astig-matism(all P＜0.05).This finding is consistent with the tendency in the control group.Conclusion A significant bur-den of preoperative corneal astigmatism is observed in cataract surgery candidates with high myopia,with more than 50％of the patients having corneal astigmatism ≥1.00 D.The corneal astigmatism of patients with high myopia is significantly greater than that of patients with normal ALs.The proportion of moderate-to-high astigmatism is significantly higher in high-myopia patients than that in patients with normal ALs.

Retinopathy caused by myopia is the first cause of irreversible blinding eye disease in China.The TCM methods to prevent and control myopia mainly include Chinese materia medica and TCM appropriate techniques,which have the advantages of good efficacy,simple operation,and few adverse reactions.This paper believed that internal and external pathogenic factors act on the brain and eyes,breaking their homeostasis,leading to rhythmic disorders,and imbalance of essence,qi and blood is the main pathogenesis of myopia.Based on the idea of"nature and human in the same rhythm"and"the same treatment for common diseases",targeting the above pathogenesis,the method of"brain-eye synchronization"was proposed to restore the homeostasis of the brain and eyes to prevent and control myopia in children and adolescents,and the treatment rules were to regulate the rhythms of the time,harmonize the qi and blood,nourish the blood to soften the tendons,and replenish the essence and blood,so as to achieve the effect of brain-eye synchronization and the treatment of the spirit and the body together.This article summarized the theoretical basis of"brain-eye synchronization"and its clinical application in traditional Chinese and Western medicine,with a view to providing new ideas for the prevention and control of myopia in children and adolescents.

Genomic imprinting refers to the phenomenon of differential expression of two alleles due to their different parental origins. Genes that produce genomic imprinting are usually called imprinted genes. The genetic effect caused by the presence of imprinted genes is called parent-of-origin effect. Parent-of-origin effect and genomic imprinting play important roles in the pathophysiological mechanism and occurrence and development of cardio-metabolic diseases. In-depth exploration of the law and potential roles of imprinted genes and parent-of-origin effects will help to better understand the mechanism of cardio-metabolic diseases, and also provide important theoretical basis for the precise treatment of diseases related to imprinted genes.

Objective:To explore the spousal correlations of total cholesterol(TC),total triglyceride(TG),low-density lipoprotein cholesterol(LDL-C),and high-density lipoprotein cholesterol(HDL-C),and to investigate the reasons behind these spousal correlations.Methods:Participants and data were from the baseline survey of family-based cohort studies in Fangshan,Beijing and Tulou,Fujian.The ori-gin of spousal correlations were explored from perspectives of convergence,assortative mating,social ho-mogamy.Pearson's correlation and generalized linear models(GLM)were used to estimate the spousal correlation.Convergence was assessed by Pearson's correlation between the phenotypic differences be-tween couples and the duration of marriage,with GLM used for further validation.Pearson's correlation of genetic risk scores(GRS)and couple-specific Mendelian randomization(MR)were calculated to assess the genetic correlation and possible causal relationships between spouses.Two-independent-sample t-tests were used to compare GRS consistency across subgroups divided by education attainment,couple-specific MR and Q statistics used to test assortative mating in subgroups and intergroup differences.Results:In the study,342 couples(287 couples from Fangshan and 55 couples from Fujian)were included,with the average age of(64.91±8.76)years.Spousal correlations of TC,TG,HDL-C,and LDL-C showed statistically significant associations both before and after adjusting for covariates,with effect sizes of 0.229(95％CI:0.125-0.327),0.257(95％CI:0.155-0.354),0.179(95％CI:0.074-0.280),and 0.181(95％CI:0.076-0.282).For convergence,for each additional year of marriage,ΔTC increased by 0.016 mmol/L(95％CI:0.001-0.033 mmol/L),and ΔLDL-C increased by 0.017 mmol/L(95％CI:0.002-0.031 mmol/L).For assortative mating,GRS correlations and results of couple specific MR didn't show any statistical significance.For social homogamy,no differences in GRS or assortative mating were found between subgroups stratified by education attainment.Conclusion:The blood lipid in participants exhibit spousal phenotypic correlations,however,no effects of convergence,assortative mating or social homogamy were observed.More independent studies with larger sample sizes are warranted to further validate these findings in the future.
