Objective To evaluate the clinical efficacy of hip-knee-ankle active and passive exercise therapy in patients with early-to mid-stage knee osteoarthritis(KOA).Methods A total of 180 patients with early to mid-stage knee osteoarthritis(KOA)were recruited from the First Affiliated Hospital of Hebei University of Tradi-tional Chinese Medicine between March 2023 and March 2024.Patients were randomly assigned to one of four groups:active movement group,passive movement group,combined movement group,and control group,with 45 patients in each group.The active movement group received hip-knee-ankle active movement therapy daily until the end of follow-up.The passive movement group underwent hip-knee-ankle passive movement therapy three times per week for two weeks.The combined movement group received both active and passive therapies.The control group was administered oral celecoxib capsules(200 mg once daily for two weeks).Joint function was assessed in all four groups before treatment,at two weeks post-treatment,and at 14 weeks post-treatment.The primary outcome measure was the WOMAC joint function score,while secondary outcomes included the WOMAC pain score,stiffness score,and quality of life score(SF-12).Results A total of 160 patients completed the trial,with 39 in the active group,42 in the passive group,40 in the combined group,and 39 in the control group.There were no significant differences in baseline characteristics among the groups(P>0.05).Compared to baseline,the WOMAC scores for function,pain,and stiffness in the passive,combined,and control groups decreased significantly at both 2 and 14 weeks post-treatment(P<0.05),while the SF-12 scores increased significantly(P<0.05).Between 2 and 14 weeks post-treat-ment,the active and combined groups showed further significant decreases in WOMAC function,pain,and stiffness scores(P<0.05)and increases in SF-12 scores(P<0.05).At 2 weeks post-treatment,compared to the control group,the passive and combined groups exhibited significantly lower WOMAC function scores(P<0.05),with no significant difference between the passive and combined groups(P>0.05).By 14 weeks post-treatment,the active and combined groups demonstrated significantly lower WOMAC function scores(P<0.05),with the combined group showing a significantly lower score than the active group(P<0.05).Conclusion The four therapeutic approaches demonstrate a certain degree of efficacy in improving joint function for patients with early and mid-stage KOA.The passive therapy group exhibits superior short-term outcomes,while the active therapy group shows better long-term benefits.The combined therapy group presents notable advantages in both short-term and long-term effi-cacy,although its short-term effectiveness does not surpass that of the passive therapy group.It is recommended for patients with early and mid-stage KOA who have underlying gastrointestinal and cardiovascular conditions.

Objective To investigate the potential role and underlying mechanisms of Pleckstrin homology-like Domain,Family A,Member 1(PHLDA1)in ischemic cardiomyopathy(ICM).Methods In this study,male Balb/C mice were administered control AAV9-U6 and AAV9-U6-shPHLDA1 vectors via tail vein injec-tion.Two weeks later,mice were randomly divided into four groups:two groups underwent coronary artery ligation to induce an acute myocardial infarction(MI)model,while the other two groups underwent sham sur-gery.Protein expression levels were assessed using Western blotting,immunofluorescence,and real-time fluo-rescence quantitative PCR(qPCR).Myocardial morphology and cardiac fibrosis progression were evaluated through immunohistochemistry and Masson staining.Results The results of immunoblotting and immunoflu-orescence experiments showed that PHLDA1 expression was elevated in the myocardial tissue of the construc-ted MI mouse model.Inhibiting the expression of PHLDA1 in the MI mouse model could significantly improve its survival rate.Immunohistochemical and Masson staining results showed that the cardiac outcome of MI mice was negatively correlated with PHLDA1 expression(P<0.05).In the MI model,inhibiting the expres-sion of PHLDA1 could promote the phosphorylation of phosphatidylinositol 3-kinase(PI3K)/protein kinase B(Akt)in myocardial tissue.Overexpression of PHLDA1 significantly inhibited the phosphorylation of PI3K/Akt in myocardial tissue.Conclusion PHLDA1 plays an important role in improving the cardiac outcomes of ICM,and inhibiting PHLDA1 expression can alleviate ischemic cardiomyopathy by promoting PI3K/Akt phos-phorylation.

Objective To investigate the efficacy and safety of compound cantharidis capsule combined with pemetrexed and platinum-based drugs in the treatment of elderly patients with advanced lungadenocarcinoma.Methods A total of 80 patients with advanced lung adenocarcinoma were retro-spectively selected as the study subjects.According to the treatment regimen,they were divided into chemotherapy group(treated with pemetrexed and platinum-based drugs)and traditional Chinese med-icine combined with chemotherapy group(treated with compound cantharidis capsule combined with-pemetrexed and platinum-based drugs),with 40 cases in each group.The short-term efficacy,serum tumor marker[carcinoembryonic antigen(CEA),carbohydrate antigen 72-4(CA72-4),carbohydrate antigen 125(CA125)]levels,and the incidence of adverse reactions were observed and compared between the two groups.The patients were followed up,and the progression-free survival(PFS)and overall survival(OS)of the two groups were recorded.Results The objective response rate(ORR)and disease control rate(DCR)in the traditional Chinese medicine combined with chemotherapy group were higher than those in the chemotherapy group,with statistically significant differences(P＜0.05).After treatment,the serum CEA,CA72-4 and CA125 levels in both groups were lower than those before treatment,and the levels in the traditional Chinese medicine combined with chemotherapy group were lower than those in the chemotherapy group,with statistically significant differences(P＜0.05).There was no statistically significant difference in the incidence of grade 3 to 4 adverse reac-tions between the two groups(P＞0.05).The progression-free survival rate and overall survival rate in the traditional Chinese medicine combined with chemotherapy group were higher than those in the chemotherapy group,with statistically significant differences(P＜0.05).Conclusion Compound cantharidis capsule combined with pemetrexed and platinum-based drugs can significantly improve the ORR and DCR,reduce serum tumor marker levels,prolong the survival of patients with ad-vanced lung adenocarcinoma,and has good safety.

OBJECTIVE: To analyze the clinical phenotype and genetic basis of four children with CHARGE syndrome. METHODS: A retrospective analysis was conducted on four children diagnosed with CHARGE syndrome at Xiamen Children's Hospital from May 2019 to May 2025. Peripheral venous blood samples were collected from the children and their parents and subjected to trio-whole exome sequencing. Candidate variants were verified by Sanger sequencing. Online tools were used for the conservation analysis and protein structure prediction. This study was approved by the Medical Ethics Committee of the Hospital (Ethics No.: 2024-126). RESULTS: The four children have included two neonates, one infant and one child, with their age at the initial diagnosis ranging from 16 days after birth to 11 years old. Their initial manifestations were not typical of CHARGE syndrome. All children were found to harbor missense variants of the CHD7 gene, including c.3059T>C (p.L1020S), c.3302G>A (p.C1101Y), c.5879C>T (p.S1960F) and c.8093C>T (p.S2698L). Sanger sequencing confirmed that two were de novo variants, and two were inherited from their parents. In child 1, the leucine at position 1020 was highly conserved, and the p.L1020S variant did not alter the spatial structure and hydrogen bond connections of the CHD7 protein, though the shape of the binding cavity and the number and distribution of binding probe clusters have changed. In child 4, an unreported variant in the epilepsy gene SCN9A (c.2152T>C, p.Y718H) was detected, along with bilateral lower limb deformities. Literature review suggested that missense variants of the CHD7 gene were most common (32.1%) among the Chinese population, whilst nonsense variants had the highest lethality rate (41.2%) in neonates. CONCLUSION Variants of the CHD7 gene probably underlay the pathogenesis in the four children. Changes in the binding sites and binding cavity morphology play an important role in CHARGE syndrome. The types of genetic variants in CHARGE patients may vary between different regions and races.

Objective To investigate the correlation between peripheral blood CD14+CD16+monocytes and IgG N-glycosyl levels and disease activity in patients with systemic lupus erythematosus(SLE).Methods A total of 109 SLE patients admitted to Xingtai Cental Hospital from August 2021 to November 2024 were retrospectively selected as the study objects.According to SLE disease activity index(SLE-DAI),the patients were divided into active group(n=52)and stable group(n=57).In addition,56 patients who underwent physical examination during the same period were selected as the control group.Clinical data of patients were collected,CD14+CD16+mononuclear cells were detected by flow cytometry(FCM),and IgG N-glycosyl levels were detected by hydrophilic interaction chromatography-mass spectrometry.Logistic regression analysis was performed to analyze the influencing factors of SLE-DAI,and multicollinearity test[variance inflation factor(VIF)]was performed for independent variables.The prediction model of disease activity was constructed.The effectiveness of the predictive model was evaluated by describing the recviver operator characteristic(ROC)curve and calculating the area under the curve(AUC)value.Hosmer-Lemeshow goodness-of-fit test predicted the calibration degree of the model.Results The levels of WBC,Hb,PLT,ALB,complement C3 and complement C4 in control group were higher than those in SLE group(t=8.917～22.171),and the levels of CRP were lower than those in SLE group(t=-17.359),with differences were statistical significance(all P<0.05).The CRP level and the proportion of CD14+CD16+mononuclear cells in the active group were higher than those in the stable group,and the differences were statistically significant(t=5.449,11.112,all P<0.05).The IgG glycosylation characteristics of galactosylation,sialylation and N-acetylglucosamine modification were lower than those in the stable group,and the differences were statistical significance(Z=-2.432～-0.158,all P<0.05).Spearman correlation analysis showed that the proportion of CD14+CD16+monocytes was significantly negatively correlated with IgG galactosylation,sialylation level and bisection N-acetylglucosamine modification(r=-0.656,-0.531,-0.608,all P<0.01).CD14+CD16+monocyte ratio was positively correlated with SLE-DIA(r=0.581,all P<0.01).IgG galactosylation,sialylation levels and bisection N-acetylglucosamine modification were negatively correlated with SLE-DIA(r=-0.645,-0.609,-0.503,all P<0.01).Logistic regression analysis showed that CRP>8.21mg/L,CD14+CD16+≥16.17%,sialylation<22.05%and isotropic N-acetylglucosamine modification<16.53%were independent risk factors for disease activity in SLE patients(Wald χ2=4.471～12.811,all P<0.05).The VIF values of the above independent variables were all less than 10.By establishing the Logistic regression prediction model and drawing the ROC curve,the AUC value for diagnosing SLE disease activity was 0.821(95%CI:0.733～0.905),the sensitivity,specificity and the Yodon index were 85.37%,75.67%,0.677,respectively.and the P values of Hosmer-Lemeshow goodness-of-fit test models were 0.568,respectively.Conclusion The proportion of CD14+CD16+monocytes in peripheral blood of SLE patients increase significantly,and the level of IgG glycosylation characteristics decrease,both of which are correlated with SLE-DIA.The predictive model constructed based on the two had a good ability to distinguish SLE-DIA from inactive state,with high sensitivity and moderate specificity conducive to early clinical recognition,and the model fitting effect is good.SLE-DIA can be evaluated more accurately.
