ObjectiveTo investigate the influencing factors for traditional Chinese medicine （TCM） syndromes of primary liver cancer， and to provide a theoretical basis for the TCM syndrome differentiation and standardized treatment of liver cancer. MethodsTCM syndrome differentiation was performed for 415 patients who were admitted to Shanxi Institute of Traditional Chinese Medicine and were diagnosed with primary liver cancer based on pathological or clinical examinations from January 2019 to December 2023. The chi-square test was used for comparison of categorical data between groups， and the unordered polytomous logistic regression model was used to investigate the influencing factors for TCM syndromes of liver cancer. ResultsThe common initial symptoms of the 415 patients with primary liver cancer included pain in the liver area （31.81%）， abdominal distension （25.30%）， abdominal pain （15.18%）， and weakness （13.98%）， and the main clinical symptoms included poor appetite （70.84%）， fatigue （69.16%）， pain in the liver area （67.47%）， poor sleep （59.04%）， abdominal distension （53.01%）， and constipation （52.53%）. There were significant differences in TCM syndromes between patients with different sexes， courses of the disease， clinical stages， Child-Pugh classes， presence or absence of intrahepatic and extrahepatic metastasis， and presence or absence of transcatheter arterial chemoembolization （TACE） and radiofrequency ablation （all P<0.05）. The logistic regression analysis showed that male sex was a risk factor for damp-heat accumulation （odds ratio ［OR］=2.036， P=0.048） and the syndrome of spleen-kidney Yang deficiency （OR=5.240， P<0.001）； a course of disease of<1 year was a risk factor for damp-heat accumulation （OR=2.837， P=0.004） and syndrome of Qi stagnation and blood stasis （OR=2.317， P=0.021）， but it was a protective factor against syndrome of spleen-kidney Yang deficiency （OR=0.385， P=0.005）； Child-Pugh class A/B was a protective factor against liver-kidney Yin deficiency （OR=0.079， P<0.001）； intrahepatic metastasis was a risk factor for liver-kidney Yin deficiency （OR=5.117， P=0.003） and syndrome of spleen-kidney Yang deficiency （OR=3.303， P=0.010）； TACE was a protective factor against liver-kidney Yin deficiency （OR=0.171， P<0.001） and syndrome of spleen-kidney Yang deficiency （OR=0.138， P<0.001）； radiofrequency ablation was a risk factor for damp-heat accumulation （OR=4.408， P<0.001） and liver-kidney Yin deficiency （OR=32.036， P<0.001）. ConclusionSex， course of disease， Child-Pugh class， intrahepatic metastasis， TACE， and radiofrequency ablation are the main influencing factors for TCM syndromes of liver cancer.

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.

OBJECTIVES: To investigate the inhibitory effect of Fuzheng Huaji Decoction against non-small cell lung cancer (NSCLC) cells in vitro and explore the underlying mechanism. METHODS: The active ingredients and targets of Fuzheng Huaji Decoction were identified using TCMSP and SwissTargetPrediction databases. NSCLC-related targets from GeneCards and PharmGKB were intersected with the targets of the Decoction, and a protein-protein interaction (PPI) network was constructed to identify the core targets, which were analyzed with GO and KEGG pathway enrichment analysis. Cultured A549 cells were treated with different concentrations of Fuzheng Huaji Decoction-medicated serum, and the changes in cell proliferation, apoptosis, and protein expressions were examined using CCK-8 assay, annexin V-FITC/PI staining and Western blotting. RESULTS: Fuzheng Huaji Decoction contained 140 active ingredients, and 707 drug-disease intersecting targets were identified. Among these targets, TP53, AKT1, HIF1A, GAPDH, ALB, EGFR, CTNNB1, and TNF were identified as the core targets which were involved in the biological processes related to kinases and receptors and the PI3K-AKT, Ras, calcium, and MAPK pathways. Molecular docking studies indicated strong binding affinity of the active ingredients with TP53, AKT1, and HIF1A. In cultured A549 cells, treatment with 2.5%, 5%, and 10% Fuzheng Huaji Decoction-medicated serum significantly inhibited cell proliferation, promoted cell apoptosis, and downregulated the expression levels of HIF1A, p-AKT (Thr308), and TP53 proteins. CONCLUSIONS Fuzheng Huaji Decoction inhibits proliferation of NSCLC cells possibly by downregulating the expressions of HIF1A, p-AKT (Thr308), and TP53.

Objective To investigate the effect of the anti-oxidized low density lipoprotein(ox-LDL)IgM subclass antibody 3A6 on the atherosclerotic plaque formation in ApoE-/-mice.Methods The ApoE-/-mice were randomly divided into three groups:control group(intraperitoneal injection of normal saline),5G8group(intraperitoneal injection of nature anti-LDL IgM subclass antibody)and 3A6group(intraperitoneal injection of natural anti-ox-LDL IgM subclass antibody),with 6mice in each group.The body weight of mice and the level of serum lipid in each group were measured after 12 weeks of high-fat and high-cholesterol diet.hematoxylin-eosin staining was used to analyze the pathological changes and plaque area of the aorta in mice.Results There was no significant difference in body weight,serum lipid level and ox-LDL level among the three groups(P=0.087).Compared with the control group,the area of atherosclerotic plaque was significantly decreased in the 3A6group(P=0.023).Conclusion The natural IgM subclass antibody 3A6 can effectively inhibit the formation of atherosclerotic plaque in ApoE-/-mice.

Objective:To analyze the epidemiological and clinical characteristics of children with acute brucellosis, providing reference for early diagnosis and standardized treatment of brucellosis in children.Methods:The data of 140 children with acute brucellosis at Xi'an Children's Hospital from April 2012 to October 2021 were collected. Their general information, epidemiological characteristics, clinical manifestations, laboratory and imaging examinations, treatment and prognosis were analyzed retrospectively.Results:Among 140 children with acute brucellosis, there were 78 males and 62 females, with a median age of onset and interquartile range of 3.4 (1.8, 5.8) years; 88.6% (124/140) of these children came from rural areas. The peak season for the onset of brucellosis was summer (47.1%, 66/140); 92.9% (130/140) had a confirmed epidemiological history; 7.9% (11/140) of the affected children were latent carriers. Among the 129 children with obvious clinical manifestations, fever accounted for 99.2% (128/129), hyperhidrosis accounted for 52.7% (68/129), and involvement of the reticuloendothelial system, joints, and nervous system accounted for 46.5% (60/129), 44.2% (57/129), and 6.2% (8/129), respectively, joint effusion accounted for 64.9% (37/57). All patients tested positive for tiger red plate agglutination test; 97.9% (137/140) of the patients had a serum tube agglutination test titer ≥1 ∶ 100. Positive blood culture accounted for 85.7% (120/140). The positive detection rate of serum tube agglutination test was higher than that of blood culture (χ 2 = 13.69, P < 0.001). Brucella was cultured from the cerebrospinal fluid of 8 children with concomitant encephalitis. The initial treatment plan for all children was oral compound sulfamethoxazole/doxycycline + rifampicin. In cases of arthritis, osteomyelitis or encephalitis, third-generation cephalosporins or meropenem were used intravenously at the same time. Dexamethasone was used for patients suffered from bilateral abductor nerve damage. All patients were cured without recurrence. Two cases had sequelae, namely introverted vision in the right eye and knee joint movement disorders. Conclusions:Most children with acute brucellosis have a confirmed epidemiological history and are mainly distributed in rural areas. The main clinical manifestation is fever, and joint involvement is also common. Standardized treatment can cure them.

The onset of myasthenia gravis (MG) after allogeneic hematopoietic stem cell transplantation (allo-HSCT) seriously threatens the survival of patients, since it is acute, and is prone to rapid progression. Two patients with acute myeloid leukemia (AML), who had undergone allo-HSCT developed shortness of breath, and gradually developed cervical weakness and dyspnea. The acetylcholine receptor (AChR) antibody and neostigmine test enabled the diagnosis of MG. The condition of the patients improved after treatment with pyridostigmine bromide, glucocorticoids and rituximab.

Myositis antibodies are divided into myositis-specific autoantibodies(MSA)and myositis-associated autoantibodies(MAA).There are heterogeneity in the mechanism,clinical features and prognosis of interstitial lung disease(ILD)in the different myositis antibodies.In MSA,anti-melanoma differentiation-related gene 5(MDA5)antibody and anti-aminoacyl synthetase(ARS)antibody are highly correlated with the occurrence of ILD.Patients with MDA5+DM-ILD usually have a rapidly progressive and poor prognosis.The progress of ILD in ARS+DM patients was slow,and the response to treatment is good,but it is easy to relapse.In MAA,anti-Ro52 antibodies often coexist with MSA antibodies,and clinical manifestation is closely related to coexisting antibodies.This review has summarized roles of myositis antibodies in ILD.

Objective To evaluate the dosimetric effect of three-dimensional(3D)printed headrests made of different materials in radiotherapy for head and neck tumor,and to evaluate whether the existence of customized 3D-printed headrest can be neglected during planning phase by comparing differences in target area doses,homogeneity index(HI),conformity index(CI),monitor units(MU),and organ-at-risk(OAR)dose.Methods Ten patients with head and neck tumors,including 5 cases with nasopharyngeal carcinoma and 5 with other head and neck tumors,were enrolled.The headrest contours were outlined using Monaco treatment planning system,and with the same calculation parameters,treatment plans were generated for scenarios without a headrest,with a standard headrest,and with 3D-printed headrests made of 10%filled polylactic acid and thermoplastic polyurethane.The target area doses,OAR dose,MU,and other results were recorded and subjected to statistical analysis.Results No significant differences were observed among the 4 groups(ignoring headrest,standard headrest,3D-printed headrests with 10%filled polylactic acid and thermoplastic polyurethane)in parameters such as D95,D5,Dmean,HI,CI,MU,and OAR dose(the maximum dose to the spinal cord)(P>0.05).Considering the presence of the headrest,significant differences were found in CI for nasopharyngeal carcinoma and other head and neck tumors(P<0.05).Conclusion During the planning phase,the existence of customized 3D-printed headrest can be ignored,but it should be noted that the presence of a headrest may reduce the MU in radiotherapy plans.When considering the headrest,the average CI of patients with other head and neck tumors is significantly higher than that with nasopharyngeal carcinoma.
