Objective: To investigate the efficacy, safety, and traditional Chinese medicine (TCM) medication patterns of rituximab (RTX) combined with TCM on treating children with steroid-dependent nephrotic syndrome (SDNS). Methods: One hundred and forty-three children with SDNS who visited the Pediatric Nephrology Department of the First Affiliated Hospital of Henan University of Chinese Medicine from January 2018 to December 2022 were enrolled. A cohort study design was adopted, with " RTX treatment" as the exposure factor. Children who met this exposure factor were assigned to the RTX cohort (RTX, glucocorticoid, immunosuppressive agent, combined with traditional Chinese medicine syndrome differentiation treatment), whereas those who did not were assigned to the basic treatment cohort (glucocorticoid, immunosuppressive agent, combined with traditional Chinese medicine syndrome differentiation treatment ), and followed up for 6 months. The frequency of urinary protein recurrences, urinary protein remission duration, proportion and duration of steroid reduction and cessation, cumulative usage of steroids, proportion of recurrence, recurrence amount of steroid used, efficacy of TCM syndrome, and laboratory and safety indicators after treatment, and height and CD19+ B cell count before and after treatment were compared between the two cohorts. The medication patterns of TCM in the two cohorts were analyzed using frequency statistics, association rule analysis, and systematic clustering analysis. Results: Compared with the basic treatment cohort, the RTX cohort showed a decrease in the frequency of urinary protein recurrence, extended sustained remission of urinary protein, an increase in the proportion of steroid reduction and cessation, a shorter duration of steroid reduction and cessation, a decrease in cumulative steroid dosage, a lower recurrence rate, a decrease in CD19+ B cell count, and a decrease in 24-h urinary total protein quantification and the level of cholesterol (P<0.05). No significant difference in the recurrence amount of steroid used, height, TCM syndrome efficacy, albumin, aspartate transaminase, blood urea nitrogen, platelet count, and safety indicators between the two cohorts. Children with SDNS were mostly characterized by qi and yin deficiency syndrome, followed by spleen and kidney yang deficiency syndrome. A total of 175 TCMs were included, including 28 high-frequency drugs such as Huangqi, Fuling, Gancao, Baizhu, Dangshen, and Jiuyurou. The primary use of medication is to nourish the qi and spleen, nourish the kidney, and warm yang. The analysis of association rules yielded eight binary associations and ten three-phase associations, with Huangqi, Baizhu, Fuling, and Dangshen, being the most closely related. Cluster analysis identified four TCM combinations, primarily focusing on tonifying kidney and replenishing essence, benefiting qi and nourishing yin, and removing blood stasis. Conclusion RTX combined with TCM syndrome differentiation treatment can reduce the recurrence frequency of SDNS, prolong the remission period, reduce the glucocorticoid dosage, and have no marked effect on height growth. No apparent adverse reactions were observed. TCM should focus on nourishing qi and yin while removing blood stasis.

Objective: To analyze the phylogenetic characteristics of VP1 gene of Coxsackievirus A10 (CVA10) isolates from 2004 to 2023, and to understand the genetic evolution and epidemic trends of CVA10, so as to provide references for the prevention and control of hand, foot, and mouth disease. Methods: The full-length sequences of the VP1 region of CVA10 isolates were retrieved from the BV-BRC database before December 15, 2024. Gene typing, sequence analysis, evolutionary analysis, and amino acid mutation site analysis were conducted using bioinformatics software. Results: A total of 1 253 CVA10 isolates VP1 region nucleotide full-length sequences from 2004 to 2023 were included, with 9 strains from 2004 to 2008, 338 strains from 2009 to 2012, and 906 strains from 2013 to 2023. China had the highest number of CVA10 isolates, with 1 143 strains accounting for 91.22%, and the predominant genotype was C3. Compared to the prototype strain, the nucleotide sequence homology of the VP1 region of CVA10 isolates ranged from 74.94% to 77.63%, while the amino acid sequence homology ranged from 88.59% to 93.62%. The third codon position preferred cytosine and thymine. The top three most abundant amino acids were threonine, alanine, and valine. The average relative synonymous codon usage of 30 amino acid codon groups was greater than 1. The average amino acid substitution entropy value was 0.04, with four amino acid mutation-prone sites identified, and the mutation-prone rate was 1.35%. Conclusions From 2004 to 2023, the majority of CVA10 isolates were primarily sourced from China, with genotype C3 being the predominant circulating strain in China. The nucleotide homology between the CVA10 isolates and the prototype strain was relatively low, and mutation-prone sites were identified, indicating that enhanced monitoring of viral variation is necessary.

OBJECTIVE: To analyze RELT gene mutation found in a pedigree with clinical features and inheritable pattern consistent with amelogenesis imperfecta (AI) in China, and to study the relationship between its genotype and phenotype. METHODS: Clinical and radiological features were recorded for the affected individuals. Peripheral venous blood samples of the patient and family members were collected for further study, and the genomic DNA was extracted to identify the pathogenic gene. Whole exome sequencing (WES) was performed to analyze the possible pathogenic genes, and Sanger sequencing was performed for validation. SIFT and PolyPhen-2 were used to predict and analyze the mutation effect. Comparison of RELT amino acids across different species were performed by using Uniprot website. In addition, the three-dimen-sional structures of the wild type and mutant proteins were predicted by Alphafold 2. RESULTS: The proband exhibited typical hypocalcified AI, with heavy wear, soft enamel, rough and discolored surface, and partial enamel loss, while his parents didn ' t have similar manifestations. WES and Sanger sequencing results indicated that the proband carries a homozygous frameshift mutation in RELT gene, NM_032871.3: c.1169_1170del, and both of his parents were carriers. This mutation was predicted to be pathogenic by SIFT and PolyPhen-2. Up to now, there were 11 mutation sites in RELT gene were reported to be associated with AI, and all of the patients exhibited with hypocalcified AI. Compared with the wild-type RELT protein, the mutant protein p. Pro390fs35 conformation terminated prematurely, affecting the normal function of the protein. CONCLUSION Through phenotype analysis, gene sequencing, and functional prediction of a Chinese family with typical amelogenesis imperfecta, this study found that RELT gene frameshift mutation can lead to protein dysfunction in AI patients. Further research will focus on the role and mechanism of RELT in enamel development at the molecular and animal levels, providing molecular biology evidence for the genetic counseling, prenatal diagnosis, and early prevention and treatment of AI.

Peptide receptor radionuclide therapy (PRRT) with radiolabeled SSTR2 agonists is a treatment option that is highly effective in controlling metastatic and progressive neuroendocrine tumors (NETs). Previous studies have shown that an SSTR2 agonist combined with albumin binding moiety Evans blue (denoted as ¹⁷⁷Lu-EB-TATE) is characterized by a higher tumor uptake and residence time in preclinical models and in patients with metastatic NETs. This study aimed to enhance the in vivo stability, pharmacokinetics, and pharmacodynamics of ¹⁷⁷Lu-EB-TATE by replacing the maleimide-thiol group with a polyethylene glycol chain, resulting in a novel EB conjugated SSTR2-targeting radiopharmaceutical, ¹⁷⁷Lu-LNC1010, for PRRT. In preclinical studies, ¹⁷⁷Lu-LNC1010 exhibited good stability and SSTR2-binding affinity in AR42J tumor cells and enhanced uptake and prolonged retention in AR42J tumor xenografts. Thereafter, we presented the first-in-human dose escalation study of ¹⁷⁷Lu-LNC1010 in patients with advanced/metastatic NETs. ¹⁷⁷Lu-LNC1010 was well-tolerated by all patients, with minor adverse effects, and exhibited significant uptake and prolonged retention in tumor lesions, with higher tumor radiation doses than those of ¹⁷⁷Lu-EB-TATE. Preliminary PRRT efficacy results showed an 83% disease control rate and a 42% overall response rate after two ¹⁷⁷Lu-LNC1010 treatment cycles. These encouraging findings warrant further investigations through multicenter, prospective, and randomized controlled trials.

Acute kidney injury (AKI) has high morbidity and mortality, but effective clinical drugs and management are lacking. Previous studies have suggested that macrophages play a crucial role in the inflammatory response to AKI and may serve as potential therapeutic targets. Emerging evidence has highlighted the importance of forkhead box protein O1 (FoxO1) in mediating macrophage activation and polarization in various diseases, but the specific mechanisms by which FoxO1 regulates macrophages during AKI remain unclear. The present study aimed to investigate the role of FoxO1 in macrophages in the pathogenesis of AKI. We observed a significant upregulation of FoxO1 in kidney macrophages following ischemia-reperfusion (I/R) injury. Additionally, our findings demonstrated that the administration of FoxO1 inhibitor AS1842856-encapsulated liposome (AS-Lipo), mainly acting on macrophages, effectively mitigated renal injury induced by I/R injury in mice. By generating myeloid-specific FoxO1-knockout mice, we further observed that the deficiency of FoxO1 in myeloid cells protected against I/R injury-induced AKI. Furthermore, our study provided evidence of FoxO1's pivotal role in macrophage chemotaxis, inflammation, and migration. Moreover, the impact of FoxO1 on the regulation of macrophage migration was mediated through RhoA guanine nucleotide exchange factor 1 (ARHGEF1), indicating that ARHGEF1 may serve as a potential intermediary between FoxO1 and the activity of the RhoA pathway. Consequently, our findings propose that FoxO1 plays a crucial role as a mediator and biomarker in the context of AKI. Targeting macrophage FoxO1 pharmacologically could potentially offer a promising therapeutic approach for AKI.

Objective To investigate the significance of spread through air spaces (STAS) in early-stage non-small cell lung cancer (NSCLC) patients undergoing either sublobar resection or lobectomy by pooling evidence available, and to assess the accuracy of frozen sections in determining types of resection among patients with suspected presence of STAS. Methods Studies were identified by searching databases including PubMed, EMbase, Web of Science, and The Cochrane Library from inception to July 2022. Two researchers independently searched, screened, evaluated literature, and extracted data. Statistical analysis was conducted using RevMan 5.4 and STATA 15.0. The Newcastle-Ottawa Scale (NOS) was used to evaluate the quality of the study. Results A total of 26 studies involving 23 surgical related studies (12 266 patients) were included, among which, 11 compared the outcomes of lobectomy with sublobar resection in the STAS-positive patients. NOS score≥6 points. Meta-analysis indicated that presence of STAS shortened patients' survival in both lobectomy group and sublobar resection group (RFS: HR=2.27, 95%CI 1.96-2.63, P＜0.01; OS: HR=2.08, 95%CI 1.74-2.49, P＜0.01). Moreover, lobectomy brought additional survival benefits to STAS-positive patients compared with sublobar resection (RFS: HR=1.97, 95%CI 1.59-2.44, P＜0.01; OS: HR=1.91, 95%CI 1.47-2.48, P＜0.01). Four studies were included to assess the accuracy of identifying presence of STAS on intraoperative frozen sections, of which the pooled sensitivity reached 55% (95%CI 45%-64%), the pooled specificity reached 92% (95%CI 77%-97%), and the pooled area under the curve was 0.68 (95%CI 0.64-0.72) based on the data available. Conclusion This study confirms that presence of STAS is a critical risk factor for patients with early-stage NSCLC. Lobectomy should be recommended as the first choice when presence of STAS is identified on frozen sections, as lobectomy can prolong patients' survival compared with sublobar resection in STAS-positive disease. The specificity of identifying STAS on frozen sections seems to be satisfactory, which may be helpful in determining types of resection. However, more robust methods are urgently in need to make up for the limited sensitivity and accuracy of frozen sections.

This paper summarizes the experience of professor DING Yuanqing in treating post-stroke depression （PSD） of young and middle-aged patients with the method of regulating qi and promoting blood circulation. PSD is a syndrome resulting by vascular injury and impairment of brain marrow and vital activity after the stroke. Factors such as poor lifestyle， improper control of chronic diseases and sleep disorders，etc.，which can be harmful individually， or they can interact. Over time，these factors can block yang of defensive qi，obstract blood circulationg and disturb qi movement. Reverse ascending of defensive qi can generate wind and fire，generate phlegm and stasis from the fluid the blood. Qi stagnation， phlegm and stasis can combined with stagnation heat， phlegm heat， blood stasis heat which caused by stroke ， which can further aggravate pulse accumulation， damage the blood vessels and block the collaterals. Consequently， defensive qi is floating over and nutrient qi is not smooth， resulting in inadequate nourishment of the brain marrow，and disfunction of vital activity， causing depressive symptoms. Professor DING innovatively applied the method of regulating qi and promoting blood circulation. He selected the classic prescriptions such as Guizhi Decoction（桂枝汤）， Baoyuan Decoction（保元汤）， as well as self-fitting prescriptions like Erdan Decoction（二丹汤）， Erzhu Decoction（二竹汤）， to relieve qi and tonify qi，promote harmonious blood circulation， facilitate vasodilation， ease symptoms of depression， invigorate the mind， and provide an effective treatment for PSD.

ObjectiveTo investigate the efficacy and safety of cinobufagin tablets combined with thalidomide/dexamethasone （TD） regimen in the treatment of newly diagnosed multiple myeloma （NDMM） with phlegm and stasis obstruction. MethodsThe clinical data of 50 patients with NDMM of phlegm and stasis obstruction who were hospitalized at the Jiangsu Province Hospital of Chinese Medicine from June 1st， 2015 to July 31th， 2019 were retrospectively analyzed， and they were divided into a control group （bortezomib/dexamethasone-containing regimen， 27 cases） and an observation group （cinobufagin tablets combined with TD regimen， 23 cases）. The clinical efficacy and safety were compared between the two groups after two or three courses of treatment. The primary outcomes were clinical remission rate including overall response rate and deep remission rate， one-year and two-year overall survival rate， and adverse effects. The secondary outcomes were the proportion of plasma cells in bone marrow， hemoglobin， β2-microglobulin， lactate dehydrogenase， serum creatinine， blood urea nitrogen， bone pain score， and KPS functional status score （KPS score） before and after treatment. ResultsIn terms of clinical efficacy， there was no statistically significant difference （P＞0.05） in the overall response rate ［the observation group 69.57%（16/23） vs the control group 70.37% （19/27）］ and deep remission rate ［the observation group 56.52% （13/23） vs the control group 55.56% （15/27）］ between groups after the treatment. The one-year overall survival rates of the observation group and the control group were 90.9% and 92.4%， and the two-year overall survival rates were 81.8% and 80.9% respectively， with no statistically significant differences between groups （P＞0.05）. During the treatment， no renal function injury occurred in both groups. The incidence of peripheral nerve injury in the observation group was 8.70%， which was lower than 48.15% in the control group （P＜0.01）. After the treatment， the proportion of myeloma plasma cells， β2-microglobulin， serum creatinine level， and bone pain score decreased， while the hemoglobin level and KPS score increased in both groups （P＜0.05 or P＜0.01）. Compared between groups after treatment， the bone pain score of the observation group was lower than that of the control group， while the KPS score was higher than that of the control group （P＜0.05）. ConclusionThe clinical efficacy of cinobufagin tablets combined with TD in the treatment of NDMM is equivalent to bortezomib/dexamethasone-containing regimen， but the former is more helpful in relieving the pain and improving the quality of life， and has better safety.

Objective:To evaluate the correlation between the degree of posterior longitudinal ligament (PLL) injury and various parameters of vertebral body injury in patients with thoracolumbar burst fractures.Methods:A total of 48 patients with thoracolumbar burst fractures were admitted to the Spine Surgery Center of the Second Affiliated Hospital of Inner Mongolia Medical University between December 2022 and January 2024. The cohort consisted of 31 males and 17 females, with a mean age of 44.1±11.8 years (range, 18-65 years). Based on the PLL injury grading method proposed by Sun Zhaoyun, patients were classified into three groups: mild, moderate, and severe. However, due to an insufficient number of patients in the severe group ( n=3), the moderate and severe groups were combined for statistical analysis, resulting in two groups: mild, and moderate-to-severe. Patient demographic and clinical data were collected. Local kyphosis (LK), inversion angle (IA), horizontal rotation angle (HRA), increased interspinous distance (IISD), anterior vertebral body compression ratio (AVBCR), posterior vertebral body compression ratio (PVBCR), middle vertebral body compression ratio (MVBCR), the ratio of height of bone fragment (RHBF), the ratio of width of bone fragment (RWBF), and mid-sagittal canal diameter compression ratio (MSDCR) were measured. Statistical analyses were performed using SPSS 25.0. Categorical variables were expressed as frequency (percentage) and analyzed using chi-square and Fisher exact tests. Continuous variables were tested for normality, with non-normally distributed data analyzed using the rank-sum test and expressed as median (interquartile range). Multivariate logistic regression analysis was performed to identify independent risk factors, and receiver operating characteristic (ROC) curves were plotted to calculate the area under the curve (AUC) to evaluate predictive performance. Results:Among the 48 patients, only 3 were found to have severe PLL injury, necessitating the combination of the moderate and severe groups for statistical purposes. Patients in the moderate-to-severe group demonstrated significantly higher AVBCR, PVBCR, RHBF, MVBCR, MSDCR, and IA compared to the mild group ( P<0.05). Multivariate logistic regression identified AVBCR, PVBCR, MSDCR, and IA as independent risk factors for moderate-to-severe PLL injury ( OR>1, P<0.05). ROC curve analysis revealed that AVBCR, PVBCR, MSDCR, IA, and their combined index could effectively predict moderate-to-severe PLL injury ( P<0.05). Notably, the combined index showed superior predictive performance (AUC=0.970) compared to individual parameters. Threshold values were determined as follows: AVBCR>45.30%, PVBCR>12.17%, MSDCR>27.13%, IA>5.90°, and the combined index >0.61, indicating PLL damage. Conclusion:AVBCR, PVBCR, MSDCR, IA, and their combined index are significantly associated with moderate-to-severe PLL injury in thoracolumbar burst fractures. The combined index demonstrates superior predictive ability compared to single parameters, providing a reliable tool for assessing PLL integrity.

This study was performed to explore the effects of berberine(BBR)and berbamine(BA)on the apoptosis and activity of eosinophils,and to provide new ideas for the treatment of eosinophil-related diseases.Anticoagulated whole blood was taken from hospitalized patients,and eosinophils were purified by magnetic bead sorting technology,and the cell purification rate was compared by using flow cytometry.The purified eosinophils were cultured and stimulated with different concentrations of BBR and BA,and the apoptosis of eosinophils was observed using immunofluorescence microscopy.Flow cytometry was used to detect the apoptosis rate,reactive oxygen species(ROS)release,mitochondrial membrane potential,and CD11b,CD62L and CD63 molecular expression of eosinophils.Data showed that 10 μmol/L BBR displayed significant anti-apoptosis effect on eosinophils at 18 h,24 h,48 h,however,100 μmol/L and 150 μmol/L BBR displayed significant apoptosis-promoting effects on eosinophils at 24 h,48 h,especially in the early stage.BA at 5 μmol/L,15 μmol/L and 25 μmol/L showed significant apoptosis-promoting effects on eosinophils at 24 h,48 h,especially in the late stage.In eosinophils,BA stimulated the production of ROS and the decrease of mitochondrial membrane potential in a concentration-dependent manner,reaching the maximum effect at 25 μmol/L,while BBR stimulation did not change mitochondria and ROS.Pretreatment with 25 μmol/L BA significantly inhibited the increase of CD11b expression and the decrease of CD62L expression in eosinophils after eotaxin-2 stimulation.In conclusion,berberine has a bidirectional regulatory effect on the quantity of eosinophils,while berbamine promotes eosinophil apoptosis and inhibits eosinophil activation.Both compounds hold significant potential for regulating the progression of eosinophil-associated diseases,and their regulatory mechanisms need further investigation.
