This study predicts the quality markers(Q-markers) for the cough-relieving and phlegm-expelling effects of Kening Granules based on pharmacodynamics, plasma drug chemistry, network pharmacology, and pharmacokinetics. Strong ammonia solution spray and phenol red secretion assays were employed to evaluate the cough-relieving and phlegm-expelling effects of Kening Granules. Twentysix absorbed prototype components of Kening Granules were identified by ultra high performance liquid chromatography coupled with QExactive Plus quadrupole/Orbitrap high resolution mass spectrometry(UHPLC-Q-Exactive Plus Orbitrap HRMS). Through network pharmacology, 11 potential active components were screened out for the cough-relieving and phlegm-expelling effects of Kening Granules. The 11 components acted on 40 common targets such as IL6, TLR4, and STAT3, which mainly participated in PI3K/Akt, HIF-1, and EGFR signaling pathways. Pharmacokinetic quantitative analysis was performed for 7 prototype components. Three compounds including azelaic acid, caffeic acid, and vanillin were identified as Q-markers for the cough-relieving and phlegm-expelling effects of Kening Granules based on their effectiveness, transmissibility, and measurability. The results of this study are of great significance for clarifying the pharmacological substance basis, optimizing the quality standards, and promoting the clinical application of Kening Granules.

This study explores the therapeutic differences and mechanisms of salt-processed Phellodendri Chinensis Cortex in improving insulin resistance(IR) based on network pharmacology, molecular docking, and cellular experiments. The components and intersection targets of Phellodendri Chinensis Cortex in improving IR were collected from databases, and a "drug-component-target-disease" network and protein-protein interaction(PPI) network were constructed to screen core components and targets. A total of 29 active components and 240 intersection targets were identified, of which 13 were core targets. Gene Ontology(GO) and Kyoto Encyclopedia of Genes and Genomes(KEGG) pathway enrichment analyses were used to identify key signaling pathways, and molecular docking was performed to validate the binding activity between core components and targets. An IR model in HepG2 cells was induced using insulin combined with high glucose, and the effects of Phellodendri Chinensis Cortex before and after salt-processing on cell glucose consumption were evaluated. The expression of proteins related to the mitogen-activated protein kinase(MAPK) and phosphatidylinositol 3-kinase(PI3K)-protein kinase B(AKT) signaling pathways was detected by Western blot. The cellular experimental results showed that, compared with the model group, glucose consumption in the drug-treated groups was significantly increased(P<0.01), the phosphorylation level of extracellular regulated protein kinase(ERK) was decreased(P<0.05), the phosphorylation levels of PI3K and AKT were increased, and the expression of glucose transporter 4(GLUT4) was also upregulated(P<0.05). Furthermore, the effect of salt-processed Phellodendri Chinensis Cortex was better than that of raw Phellodendri Chinensis Cortex. The study demonstrates that Phellodendri Chinensis Cortex, both before and after salt-processing, improves IR by regulating the expression of related proteins in the MAPK and PI3K-AKT signaling pathways, with enhanced effects after salt-processing.

OBJECTIVE: To explore the clinical significance of circulating tumor DNA (ctDNA) in response evaluation and relapse monitoring for patients with primary mediastinal large B-cell lymphoma (PMBCL). METHODS: The clinical characteristics, efficacy and survival of 38 PMBCL patients in our hospital from January 2010 to April 2020 were retrospectively analyzed. The ctDNA monitoring was conducted by targeted next-generation sequencing (NGS). RESULTS: Among the 38 patients, 26 cases were female, and 32 cases were diagnosed with Ann Arbor stage I-II. The 5-year overall survival (OS) rate and progression-free survival (PFS) rate were 74.7% and 61.7%, respectively. Males and those with high aaIPI scores (3 points) had a relatively poor prognosis. The NGS results of 23 patients showed that STAT6 (65.2%), SOCS1 (56.5%), and TNFAIP3 (56.5%) were the most common mutated genes. Patients with stable disease (SD)/progressive disease (PD) exhibited enrichment in cell cycle, FoxO, and TNF signaling pathways. A total of 29 patients underwent end-of-treatment PET/CT (EOT PET/CT), and 16 of them received ctDNA monitoring with 12 negative. Among 6 patients with EOT PET/CT positive (Deauville 4), 4 underwent ctDNA monitoring, and 3 of them were negative, being still in continuous remission without any subsequent anti-tumor therapy. CONCLUSION CtDNA may be combined with PET/CT to assess efficacy, monitor relapse, and guide treatment of PMBCL.

OBJECTIVE: To investigate the predictive value of morphology, immunology, and cytogenetics for isocitrate dehydrogenase 1 and 2 (IDH1/2) gene mutation in newly diagnosed acute myeloid leukemia (AML) patients. METHODS: The clinical data of 186 newly diagnosed AML patients (except M3 subtype) in the First People's Hospital of Changzhou were retrospectively analyzed, and the variables associated with IDH1/2 mutation in patients were screened using LASSO regression to construct a multivariate logistic regression analysis model. The Bootstrap method was used for internal validation of the model and nomograms were used to visualize the model, and receiver operating characteristic (ROC) curve was used to evaluate the predictive performance of the model. RESULTS: A total of 60 AML patients had IDH1/2 mutation at initial diagnosis. LASSO regression screened 9 predictive variables associated with IDH1/2 mutation, including CD7, CD56, CD11b, CD15, CD64, HLA-DR, platelet count≥50×10⁹/L, isolated +8 and normal karyotype. The nomogram and ROC curve were plotted based on the above 9 variables. The area under the ROC curve (AUC) of the training set and the validation set were 0.871 and 0.806, respectively. Internal validation showed that the nomogram had good predictive ability. CONCLUSION The prediction model based on MIC typing constructed in this study has a good predictive ability for the presence of IDH1/2 mutations in newly diagnosed AML patients and has important clinical application value when the gene mutation detection results are unavailable.

Mycophenolic acid (MPA), the active moiety of both mycophenolate mofetil (MMF) and enteric-coated mycophenolate sodium (EC-MPS), serves as a primary immunosuppressant for maintaining solid organ transplants. Therapeutic drug monitoring (TDM) enhances treatment outcomes through tailored approaches. This study aimed to develop an evidence-based guideline for MPA TDM, facilitating its rational application in clinical settings. The guideline plan was drawn from the Institute of Medicine and World Health Organization (WHO) guidelines. Using the Delphi method, clinical questions and outcome indicators were generated. Systematic reviews, Grading of Recommendations Assessment, Development, and Evaluation (GRADE) evidence quality evaluations, expert opinions, and patient values guided evidence-based suggestions for the guideline. External reviews further refined the recommendations. The guideline for the TDM of MPA (IPGRP-2020CN099) consists of four sections and 16 recommendations encompassing target populations, monitoring strategies, dosage regimens, and influencing factors. High-risk populations, timing of TDM, area under the curve (AUC) versus trough concentration (C₀), target concentration ranges, monitoring frequency, and analytical methods are addressed. Formulation-specific recommendations, initial dosage regimens, populations with unique considerations, pharmacokinetic-informed dosing, body weight factors, pharmacogenetics, and drug‍-‍drug interactions are covered. The evidence-based guideline offers a comprehensive recommendation for solid organ transplant recipients undergoing MPA therapy, promoting standardization of MPA TDM, and enhancing treatment efficacy and safety.

Objective:To investigate the predictive value of controlling nutritional status (CONUT) score in the prognosis of patients with advanced diffuse large B-cell lymphoma (DLBCL).Methods:A retrospective case series study was performed. The clinical data of 654 patients newly diagnosed with advanced DLBCL diagnosed in 7 medical centers in Huaihai Lymphoma Working Group from October 2009 to January 2022 were retrospectively collected. All the patients received rituximab-based immune chemotherapy regimens. The patients were randomly assigned to the training set (458 cases) and the validation set (196 cases) in a 7:3 ratio. The clinicopathological data of patients were collected, and the CONUT score was calculated based on albumin, lymphocyte count, and total cholesterol. The optimal critical value of CONUT scote was determined by using MaxStat method. Kaplan-Meier method was used to draw survival curves; Cox proportional hazards model was used to make univariate analysis and multivariate analysis on the factors influencing overall survival (OS). The efficacy of CONUT score in combination with the International prognostic index (IPI) and an enhanced IPI (NCCN-IPI) in predicting OS was evaluated by using receiver operating characteristic (ROC) curves.Results:The median follow-up time of 654 patients was 38.1 months (95% CI: 35.3 months- 40.9 months), and the 5-year OS rate was 49.2%. According to the MaxStat method, the optimal critical value for CONUT score was determined to be 6 points. All the patients were classified into the normal nutritional status group (CONUT score ≤ 6 points, 489 cases) and the poor nutritional status group (CONUT score > 6 points, 165 cases). The results of the multivariate analysis showed that CONUT score > 6 points, male, lactate dehydrogenase >240 U/L, high white blood cell count, low hemoglobin level and age > 60 years were independent risk factors for OS of patients with advanced DLBCL (all P < 0.05). Patients in the poor nutritional status group (CONUT score > 6 points) had worse OS compared with that in the normal nutritional status group in the overall cohort of advanced DLBCL. Subgroup analysis revealed that among patients with Eastern Cooperative Oncology Group-performance status (ECOG PS) score < 2 points, IPI low-intermediate risk, IPI intermediate-high risk, NCCN-IPI low-intermediate risk, and NCCN-IPI intermediate-high risk, the patients in the poor nutritional status group (CONUT score > 6 points) had worse OS compared with that in the normal nutritional status group (CONUT score ≤ 6 points) (all P < 0.05). Conclusions:CONUT score has a certain value in the assessment of the prognosis of patients with advanced DLBCL, and its predictive efficacy is further improved when combined with IPI and NCCN-IPI.

Objective:To explore the therapeutic efficacy and prognostic factors of induction therapy for secondary central nervous system lymphoma(SCNSL).Methods:Clinical data of patients diagnosed with SCNSL from 2010 to 2021 at Guangdong Provincial People's Hospital were retrospectively collected.A retrospective cohort study was performed on all and grouped patients to analyze the efficacy and survival.Multivariate logistic regression analysis was used to explore the adverse prognostic factors.Results:Thirty-seven diffuse large B-cell lymphoma patients with secondary central involvement were included in the research.Their 2-year overall survival(OS)rate was 46.01％and median survival time was 18.1 months.The 2-year OS rates of HD-MTX group and TMZ group were 34.3％and 61％,median survival time were 8.7 and 38.3 months,and median progression-free survival time were 8.1 and 47 months,respectively.Multivariate logistic regression analysis showed that age,sex,IPI,Ann Arbor stage were correlated with patient survival time.The median survival time of patients with CD79B,KMT2D,CXCR4.ERBB2,TBL1XR1,BTG2,MYC,MYD88,and PIM1 mutations was 8.2 months,which was lower than the overall level.Conclusion:HD-MTX combined with TMZ as the first-line strategy may improve patient prognosis,and early application of gene sequencing is beneficial for evaluating prognosis.

Objective To study the effects and mechanisms of tetramethylpyrazine(TMP)on tumor necrosis factor-α(TNF-α)-induced inflammatory injury in human coronary artery endothelial cells(HCAEC).Methods HCAEC were randomly divided into four groups:the control group(no treatment),the model group(treated with TNF-α,50 ng/mL for 24 hours),the TMP group(pre-treated with TMP,80 μg/mL for 12 hours followed by TNF-α treatment for 24 hours),and the SIRT1 inhibitor group(pre-treated with TMP and the specific SIRT1 inhibitor EX527 for 12 hours followed by TNF-α treatment for 24 hours).Cell viability was assessed using the CCK-8 method,lactate dehydrogenase(LDH)activity was measured using an LDH assay kit,reactive oxygen species(ROS)levels were observed using DCFH-DA staining,expression of pyroptosis-related proteins was detected by Western blot,and SIRT1 expression was analyzed using immunofluorescence staining.Results Compared to the control group,the model group showed decreased cell viability,increased LDH activity,ROS level and expression of pyroptosis-related proteins,and decreased SIRT1 expression(P<0.05).Compared to the model group,the TMP group exhibited increased cell viability,decreased LDH activity,ROS level and expression of pyroptosis-related proteins,and increased SIRT1 expression(P<0.05).In comparison to the TMP group,the SIRT1 inhibitor group showed decreased cell viability,increased LDH activity,ROS level and expression of pyroptosis-related proteins,and decreased SIRT1 expression(P<0.05).Conclusions TMP may attenuate TNF-α-induced inflammatory injury in HCAEC,which is associated with the inhibition of pyroptosis and activation of the SIRT1 signaling pathway.

Objective To investigate the correlation between traditional Chinese medicine(TCM)syndrome elements and risk factors in children with IgA vasculitis(IgAV,also known as Henoch-Sch?nlein purpura).Methods The medical records of 131 children with IgAV were retrospectively analyzed.And then the distribution of their TCM syndrome elements was investigated,and the correlation of TCM syndrome elements with the gender,age,clinical symptoms,as well as risk factors such as mosquito bite,pathogen infection,and allergic rhinitis was analyzed.Results(1)Among the 131 children with IgAV,the diseases-location syndrome elements of IgAV involved lung in 97 cases(74.05%),spleen in 61 cases(46.56%),kidney in 54 cases(41.22%),liver in 17 cases(12.98%),and heart in 11 cases(8.40%);the disease-nature syndrome elements of IgAV involved blood stasis in 131 cases(100.00%),wind-damp in 125 cases(95.42%),wind-heat in 90 cases(68.70%),damp-heat in 72 cases(54.96%),blood heat in 49 cases(37.40%),qi deficiency in 19 cases(14.50%),and yin deficiency in three cases(2.29%).(2)There were 69 cases(52.67%)of females and 62 cases(47.33%)of males among the IgAV children,with females outnumbering males.The age group of IgAV children was predominated by five to six years old,and 10 cases(7.63%)were younger than four years old,18 cases(13.74%)were four years old,39 cases(29.77%)were five years old,34 cases(25.95%)were six years old,17 cases(12.98%)were seven years old,and 13 cases(9.92%)were older than seven years old.The disease-nature syndrome elements such as blood stasis,wind-damp,wind-heat,and damp-heat were frequently seen in the age group of five to seven years old,yin deficiency was frequently seen in the age group older than seven years,and blood stasis was seen in all age groups.(3)The results of logistic regression analysis of the correlation between TCM syndrome elements and risk factors in IgAV patients showed that allergic rhinitis was positively correlated with blood stasis[OR=2.236,95%CI(1.049-4.007)],damp-heat[OR=2.183,95%CI(1.554-3.671)]and wind-damp[OR=1.202,95%CI(1.050-2.409)];pathogen infection was positively correlated with blood stasis[OR=3.199,95%CI(1.457-4.101)]and damp-heat[OR=1.119,95%CI(1.072-2.009)];mosquito bite was positively correlated with blood stasis[OR=4.533,95%CI(1.029-9.022)]and damp-heat[OR=2.257,95%CI(1.081-13.207)];the gender was positively correlated with blood stasis[OR=1.352,95%CI(1.271-3.018)]and wind-damp[OR=1.149,95%CI(1.071-3.102)].The differences were all statistically significant(P＜0.05 or P＜0.01).Conclusion IgAV usually involves the lungs and is also related to the five zang organs.Its pathogenesis is characterized by excess in superficiality such as blood stasis and wind-damp-heat in the early stage,and is predominated by deficiency in origin such as qi deficiency and yin deficiency in the later stage.For the children with IgAV,mosquito bite,pathogen infection and allergic rhinitis are more likely to induce blood stasis and wind-damp-heat;TCM syndrome elements such as wind-heat,damp-heat,blood heat,and qi deficiency are frequently seen in the males,while TCM syndrome elements such as blood stasis,wind-damp,and yin deficiency are frequently seen in the females.
