ObjectiveThis paper aims to observe the syndrome improvement and negative antigen conversion rate of Qingxuan Daozhi formula in the treatment of influenza in children （heat accumulation in the lung and stomach syndrome）. MethodsThrough a multi-center randomized controlled methodology design，confirmed influenza cases were collected from October 2022 to April 2023 in the pediatrics department of eight hospitals，such as Dongfang Hospital of Beijing University of Chinese Medicine. A total of 180 children with influenza and heat accumulation in the lung and stomach syndrome conforming to the standard were recruited through the clinic. The sick children meeting the inclusion criteria were randomly divided into groups by a block-randomized method. The children in the experimental group were treated with Qingxuan Daozhi formula for five days，and those in the control group were treated with Oseltamivir Phosphate Granules for five days. The primary efficacy indicator was the negative conversion rate of influenza antigen detection. Secondary efficacy indicators were the Canadian acute respiratory illness and flu scale （CARIFS） and the incidence of complications，severe cases， and critical cases. Follow-up observation was conducted on the day of enrollment，48 hours after medication，72 hours after medication， and （6+1） d after medication. ResultsOne hundred and eighty participants were randomly assigned to the experimental group （90 cases） or the control group （90 cases）. All participants were followed up during the study. Comparison of influenza antigen detection results in the primary efficacy indicators showed that the average time of negative influenza antigen conversion in the experimental group was （5.29±1.25） d，and that in the control group was （5.40±1.68） d，without a statistically significant difference. After five days of intervention，52 cases in the experimental group and 51 cases in the control group converted to negative，without a statistically significant difference. CARIFS score results in the secondary efficacy indicators showed that during 72 hours after intervention，there were statistically significant differences between the experimental group and the control group in three dimensions， including headache，muscle soreness， and the need for extra care （P<0.05）. On the （6+1） days after the intervention，the differences in both the experimental group and the control group were statistically significant in 10 dimensions， including sore throat，bad sleep，uncomfortable feeling，poor spirit and fatigue，crying more than usual，the need for extra care，symptom，function，influence on parents，and total score （P<0.05）. The comparison results within the group in the dimensional scores of symptom， function， and influence on parents，as well as the CARIFS total score showed that with the delay of follow-up time，scores of both groups decreased significantly，with a statistically significant difference （P<0.01）. Inter-group comparison results showed that the mean score of the experimental group was higher than that of the control group at the time of enrollment. With the progress of intervention，the score of the experimental group was significantly decreased compared with that of the control group. At the end of follow-up，the mean score of the experimental group was lower than that of the control group，with no statistically significant difference. In terms of the incidence of complications，severe cases， and critical cases， there were no complications，severe cases， and critical cases in the two groups，without a statistically significant difference. ConclusionThe symptom improvement effect and negative antigen conversion rate of Qingxuan Daozhi formula in the treatment of influenza in children （heat accumulation in the lung and stomach syndrome） are not inferior to Oseltamivir Phosphate granules， and children's acceptance is better. It can be more widely used in clinical treatment of influenza in children （heat accumulation in the lung and stomach syndrome）.

Objective To evaluate the cost-utility of risdiplam in the treatment of pediatric spinal muscular atrophy （SMA） and analyze changes in patients’ out-of-pocket economic burden under the medical insurance scenarios. Methods A Markov model was developed from the healthcare system perspective to compare the long-term costs and quality-adjusted life years （QALYs） of risdiplam treatment versus conventional therapy. The incremental cost-utility ratio （ICUR） was calculated. One-way sensitivity analysis and probabilistic sensitivity analysis were conducted to assess the robustness of the model. On this basis, health insurance scenarios were simulated to evaluate patients’ individual economic burden. Results Base-case analysis showed that risdiplam treatment generated additional health benefits but substantially increased medical costs. The resulting ICUR did not demonstrate a clear cost-utility advantage under the current willingness-to-pay threshold. Sensitivity analyses indicated that the model results were relatively robust, with drug costs and key utility parameters being the main drivers of economic outcomes. Health insurance scenario analysis demonstrated that increasing reimbursement levels and reducing patient copayment rates could significantly alleviate patients’ financial burden. Conclusion Risdiplam for pediatric SMA faces economic challenges under the current health insurance payment framework in China. However, optimizing health insurance reimbursement policies and developing multi-tiered healthcare security mechanisms may improve its affordability and accessibility.

Hepatocellular carcinoma(HCC),which is essentially primary liver cancer,is closely related to CD8+T cell immune infiltration and immune suppression.We constructed a CD8+T cells related risk score model to pre-dict the prognosis of HCC patients and provided therapeutic guidance based on the risk score.Using integrated bulk RNA sequencing(RNA-seq)and single-cell RNA sequencing(scRNA-seq)datasets,we identified stable CD8+T cell signatures.Based on these signatures,a 3-gene risk score model,comprised of KLRB1,RGS2,and TN-FRSF1B was constructed.The risk score model was well validated through an independent external validation co-hort.We divided patients into high-risk and low-risk groups according to the risk score and compared the differ-ences in immune microenvironment between these two groups.Compared with low-risk patients,high-risk patients have higher M2-type macrophage content(P＜0.0001)and lower CD8+T cells infiltration(P＜0.0001).High-risk patients predict worse response to immunotherapy treatment than low-risk patients(P＜0.01).Drug sensitivity a-nalysis shows that PI3K-β inhibitor AZD6482 and TGFβRII inhibitor SB505124 may be suitable therapies for high-risk patients,while the IGF-1R inhibitor BMS-754807 or the novel pyrimidine-based anti-tumor metabolic drug Gemcitabine could be potential therapeutic choices for low-risk patients.Moreover,expression of these 3-gene mod-el was verified by immunohistochemistry.In summary,the establishment and validation of a CD8+T cell-derived risk model can more accurately predict the prognosis of HCC patients and guide the construction of personalized treatment plans.

Objective To investigate the impacts of long non coding RNA(LncRNA)-PH domain containing 5 antisense RNA 1(FGD5-AS1)on the proliferation,migration,and invasion of colorectal cancer(CRC)cells by regulating the miR-299-5p/recombinant lysine specific demethylase 4B(KDM4B)axis.Methods The expressions of LncRNA FGD5-AS1,miR-299-5p,and KDM4B were detected by qRT-PCR in the surgically resected CRC tissues and adjacent tissues of 34 CRC patients CRC cells HCT116 were separated into si-NC group,si-FGD5-AS1 group,si-FGD5-AS1+inhibitor NC group,and si-FGD5-AS1+miR-299-5p inhibitor group.The levels of mRNA in each group were detected.CCK8,scratch assay,and Transwell assay were ap[plied to detect the proliferation,migration,and invasion of HCT116 cells in each group.Western blot was applied to detect the expression of proteins.Dual luciferase reporter gene assay verified the interaction mechanism between LncRNA FGD5-AS1 and miR-299-5p,and between miR-299-5p and KDM4B.Results LncRNA FGD5-AS1 and KDM4B were highly expressed in CRC tissue,while miR-299-5p was low expressed in CRC tissue(P＜0.05).The expression of LncRNA FGD5-AS1 mRNA,KDM4B mRNA,OD450,scratch healing rate,invasion number,PCNA,MMP-2,MMP-9,KDM4B in the si-FGD5-AS1 group were lower than those in the si-NC group,the expression of miR-299-5p mRNA was higher than that in the si-NC group(P＜0.05).Compared with the si-FGD5-AS1 group and si-FGD5-AS1+inhibitor NC group,the expression of miR-299-5p in the si-FGD5-AS1+miR-299-5p inhibitor group decreased(P＜0.05),the KDM4B mRNA,OD450,scratch healing rate,number of invasions,and expression of PCNA,MMP-2,MMP-9,KDM4B increased(P＜0.05).LncRNA FGD5-AS1 targeted negative regulation of miR-299-5p,while miR-299-5p targeted negative regulation of KDM4B.Conclusion Knocking down LncRNA FGD5-AS1 may inhibit the proliferation,migration,and invasion of CRC cells,and its mechanism may be achieved by regulating the miR-299-5p/KDM4B signaling axis.

Objectives:To analyze the cardiac involvement of patients with Fabry disease(FD)in Anhui region.Methods:This retrospective analysis included 48 previously and currently diagnosed FD patients(25 males)in Anhui region,overall patient and gender specific cardiac involvement was analyzed.Results:The median age of FD patients is 28.0(19.0,46.0)years.The cardiac manifestations of patients with FD were most commonly characterized by palpitations/arrhythmias(13/42 cases)and exertional dyspnea(11/42 cases),electrocardiographic changes were most commonly characterized by T-wave inversion(22/42 cases),ST-segment depression(16/42 cases),and left ventricular hypervoltage(18/42 cases),cardiac structural and functional changes were most common in papillary muscle hypertrophy(29/36 cases),bilateral sign(22/37 cases)and left ventricular hypertrophy(21/46 cases),as well as reduced left ventricular global longitudinal strain(26/39 cases).Neuropathic pain(28/43 cases)was the most common extracardiac manifestation of FD patients.FD patients of different gender differed in age at diagnosis(P=0.018),alpha galactosidase A activity(P<0.001),globotriaosylsphingosine(lyso-GL3)levels(P<0.001),enzyme replacement therapy rate(P=0.043),dyshidrosis(P<0.01),and the incidence of angiokeratoma(P=0.004).Correlation analysis showed that genotype was not correlated with enzyme activity or Lyso-GL-3 levels,whereas the Sokolow-Lyon index was positively correlated with Lyso-GL-3 levels(ρ=0.423,P=0.008),and the Sokolow-Lyon indices(septal thickness:ρ=0.562,P<0.001;left ventricle posterior wall thickness:ρ=0.569,P<0.001)and QRS duration(septal thickness:ρ=0.543,P<0.001;left ventricle posterior wall thickness:ρ=0.557,P<0.001)were positively correlated with left ventricular wall thickness.Conclusions:Cardiac involvement in patients with FD in the Anhui region is characterised by palpitations or arrhythmias,accompanied by nonspecific electrocardiographic changes.Echocardiography frequently reveals papillary muscle hypertrophy.The manifestation of cardiac involvement in patients of different genders is similar.

Objective:To investigate the association of Chinese visceral adiposity index (CVAI) with arterial stiffness progression.Methods:This study was a prospective cohort study, which included participants who completed at least 1 measurement of brachial-ankle pulse wave velocity (baPWV) between 2010 and 2016, with complete physical examination data during the same period, and completed baPWV measurement during follow-up. The time of completing the first baPWV measurement was defined as the baseline. All participants were divided into 4 groups according to quartiles of baseline CVAI (<60.84, 60.84-89.67, 89.68-117.45,≥117.46). The baPWV progression was calculated (baPWV progression=(baPWV follow-up-baPWV baseline)/duration of follow-up). We assessed the association of CVAI groups with baPWV progression using multivariate linear regression models. Results:A total of 17 261 participants were included. Of these, the age was (47.6±11.6) years, and 11 285 (65.38%) were males. The results of multivariate linear regression models showed that compared with the CVAI<60.84 group, the baPWV at baseline increased by 39.62 cm/s (95% CI 28.57-50.67, P<0.01) in the 60.84-89.67 group, 76.37 cm/s (95% CI 64.71-88.04, P<0.01) in the 89.68-117.45 group, and 92.83 cm/s (95% CI 80.53-105.14, P<0.01) in the≥117.46 group. The median follow-up time was 2.49 years. Compared with the CVAI<60.84 group, annual change of baPWV progression increased by 17.17 cm/s (95% CI 10.36-23.97, P<0.01) in the 60.84-89.67 group, 24.59 cm/s (95% CI 17.38-31.80, P<0.01) in the 89.68-117.45 group, and 25.75 cm/s (95% CI 18.13-33.36, P<0.01) in the ≥117.46 group. Conclusion:Higher CVAI is closely associated with the progression of arterial stiffness, and the arterial stiffness progression accelerates with increased CVAI.
