Background Bufei Huoxue Capsule (BHC) has gradually been used in clinical practice to treat patients with pneumoconiosis in recent years. However, the comprehensive evaluation of its efficacy and safety is lacking. Objective To systematically assess the therapeutic potential of BHC for pneumoconiosis. Methods By searching 9 databases, e.g. China National Knowledge Infrastructure, Wanfang Database, VIP Chinese Science and Technology Journals Database, SinoMed, Yiigle, PubMed, Embase, Cochrane Library, and Web of Science, randomized controlled trials (RCTs) related to the use of BHC for the treatment of pneumoconiosis were identified. The search covered the period from the inception of these databases to August 31, 2025. This systematic review conformed to the Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) 2020. The included studies underwent quality appraisal by the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE). Subgroup analysis and sensitivity analysis were applied to assess the robustness of results and explore the potential heterogeneity among the studies. Results A total of 19 RCTs were included and all were reported in Chinese. The therapy containing BHC showed a superior impact on forced expiratory volume in one second (FEV₁) (95%CI: 0.38, 0.66; I²=69%, P<0.05), FEV₁% (95%CI: 3.37, 5.72; I²=12%, P<0.05), forced vital capacity (FVC) (95%CI: 0.34, 0.45; I²=0%, P<0.05), FEV₁/FVC% (95%CI: 6.29, 10.35; I²=21%, P<0.05), 6-minute walking distance (6MWD) score (95%CI: 16.32, 27.64; I²=22%, P<0.05), St. George's Respiratory Questionnaire (SGRQ) score (95%CI: −1.47, −1.05; I²=13%, P<0.05), and total effective rate (95%CI: 2.71, 6.78; I²=0%, P<0.05) in patients with pneumoconiosis. In addition, BHC had less adverse reactions reported (95%CI: 0.69, 1.74; I²=0%, P=0.70). Conclusions Combined BHC therapy can significantly improve the lung function and the quality of life in patients with pneumoconiosis, with a good safety profile. However, high-quality RCTs with multicenter, large-sample, double-blind, and standardized protocols still need to be conducted in the future to provide more reliable evidence.

Objective To investigate the neuroprotective effect of Dendrobium nobile Lindl(DNL)extract in a Caenorhabditis elegans(C.elegans)model of Parkinson's disease(PD).Methods C.elegans NL5901 and 6-hydroxydopamine(6-OHDA)induced N2,BZ555,PD4521,and CB7272 C.elegans strains were treated with DNL 7.5,15,and 30 mg/L.The survival rate,basal slowing response rate,α-synuclein(α-syn)aggregation,dopaminergic neurons(DNs),mitochondrial distribution density of body wall muscle cells,and protein levels in the membrane were observed.In addition,reactive oxygen species(ROS),superoxide dismutase(SOD)and glutathione(GSH)in 6-OHDA induced N2 was detected to explore the effect of DNL on the antioxidative stress ability of PD C.elegans models.Results Compared with that in the model group,the DN fluorescence intensity was significantly increased in nematodes treated with DNL and levodopa(L-DOPA)(P＜0.05,P＜0.0001),α-syn aggregation was significantly decreased(P＜0.05,P＜0.001,P＜0.0001),the basal slowing rate(P＜0.05,P＜0.01,P＜0.001),mitochondrial density(P＜0.05,P＜0.01,P＜0.001),mitochondrial intima protein content(P＜0.05,P＜0.001,P＜0.0001),SOD content(P＜0.05),and GSH content were all increased.The ROS content was reduced in nematodes(P＜0.01).The lifespans of N2 wild-type and PD C.elegans models were prolonged after DNL treatment(P＜0.05,P＜0.01,P＜0.001).Conclusions DNL can effectively improve motor paralysis in a C.elegans PD model,improve DN degradation,inhibit α-syn aggregation and neuronal damage,increase the antioxidative stress ability,and slow the aging process in C.elegans.

Objective To explore the value of 3D and 2D radiomics features models based on multiparameter MRI in predicting Ki-67 expression(with 14%and 20%as the critical values,respectively)in breast cancer.Methods The MRI images of 147 patients with pathologically confirmed Luminal breast cancer were analyzed retrospectively.The patients were randomly divided into training set and test set according to the ratio of 7︰3.The 3D and 2D radiomics features of intratumor and peritumor were extracted from diffusion weighted imaging(DWI),dynamic contrast enhancement(DCE)mask(S0)and DCE phase 3(S3)images.Then the models were constructed by multiple pipeline combinations of three feature normalization methods,two feature dimensionality reduction methods,four feature selection methods,and ten classifiers.The receiver operating characteristic(ROC)curve and the area under the curve(AUC)were used to evaluate the prediction performance of the models in order to select the best 3D and 2D single parame-ter(DWI,S0,S3)and multiparameter combination(S0+S3,S0+DWI,S3+DWI,S0+S3+DWI)models.Finally,the differ-ences between the models were compared by De Long test.Results With 14%as the critical value,the AUC of 3D and 2D models in the training set were 0.726-0.824 and 0.707-0.835,respectively,and those in the test set were 0.724-0.82 and 0.701-0.805.With 20%as the critical value,the AUC of 3D and 2D models in the training set were 0.743-0.868 and 0.793-0.881,respectively,and those in the test set were 0.738-0.853 and 0.743-0.814.There was no significant statistical difference between 3D and 2D models with the same parameter in the two critical values standards.Conclusion The multiparameter MRI-based radiomics models can bet-ter predict the expression of Ki-67 in breast cancer,and the models based on intratumor and peritumor 3D and 2D features have the same prediction efficiency.

Objective : To analyze the difference of urinary iodine level in Hashimoto thyroiditis ( HT) patients， and to explore the possible relationship between urinary iodine level and HT under different iodine nutritional sta- tus，so as to provide some references for reasonable iodine intake in HT patients． Methods : A total of 101 hospi- talized HT patients were selected as HT group and divided into 3 groups according to thyroid function : HT group with hyperthyroidism (41 cases) ．There were 25 cases in HT group with normal thyroid function．There were 35 cases in HT combined with hypothyroidism group．In addition，30 healthy subjects were selected as control group. Serum levels of thyroid stimulating hormone(TSH) ，triiodothyronine(T3 ) ，thyroxine (T4 ) ，thyroid peroxidase an- tibody (TPOAb) and thyroglobulin antibody (ATG) were detected by chemiluminescence assay．The size and mor- phological structure of thyroid organs were examined by ultrasonography．Urinary iodine was determined by catalytic spectrophotometry with arsenic and cerium．The nutritional status of iodine was classified into iodine deficiency ( < 100 μg/ L) ，iodine adequacy( 100 －199 μg/ L) ，iodine adequacy (200 －299 μg/ L) and iodine excess ( ≥ 300 μg/ L) ．Non-parametric test was used to compare urinary iodine level between HT group and control group，one- way ANOVA and t test were used to compare urinary iodine level between HT group and control group ，and Spearman correlation analysis was used to compare the correlation between urinary iodine level and T3 ，T4 ，TSH， ATG and TPOAb under different iodine nutrition status. Results : Compared with control group，ATG and TPOAb levels in HT group increased (P＜0. 001) ，and urinary iodine levels increased (P＜0. 05) ，with statistical signifi- cance．Compared with the control group in different thyroid function states，only the HT group with hypothyroidism increased the urinary iodine level (P＜0. 01) ，and the difference was statistically significant．Spearman correlation analysis showed that urine iodine level was positively correlated with ATG and TPOAb levels in iodine excess condi- tion (P＜0. 05) ，and urine iodine level was positively correlated with TSH level in iodine sufficient condition and iodine excess condition in HT patients (P＜0. 05) ． Conclusion The urinary iodine level of HT patients was high- er than that of normal people．When the urinary iodine level of residents is ≥ 300 μg/ L，iodine intake is prone to HT．When the urinary iodine level of HT patients is ≥ 200 μg/ L，iodine consumption is prone to hypothyroidism， and iodine intake should be limited.

Objective The aim of this study was to investigate the effects of LncRNA OTUD6B-AS1 on the proliferation,mi-gration and invasion of lung adenocarcinoma A549 cells.Methods Lung adenocarcinoma A549 cell line was cultured in vitro,and transient transfection of OTUD6B-AS1 and empty plasmid group were used as the control group.Overexpression and control cell mod-els were constructed,and divided into OTUD6B-AS1 overexpression group and empty plasmid group(NC group).The cell model was divided into the empty plasmid group(NC group)and OTUD6B-AS1 overexpression group.The transfection efficiency of OTUD6B-AS1 mRNA was verified through qRT-PCR.The CCK-8 experiment was used to detect the effect of OTUD6B-AS1 on the prolifera-tion activity of lung adenocarcinoma cells,and the Transwell assay was used to detect the effect of OTUD6B-AS1 on the migration and invasion ability of lung adenocarcinoma cells.Results Compared to the NC group,the overexpression OTUD6B-AS1 group had a sig-nificant increase in the expression of OTUD6B-AS1(P<0.05).The CCK-8 assay results showed that the proliferation activity of A549 cells in the OTUD6B-AS1 overexpression group was significantly reduced compared to the NC group(P<0.05).The results of the Transwell assay showed that the OTUD6B-AS1 overexpression group had significantly lower cell migration and invasion abilities than the NC group(P<0.05).Conclusion Overexpression lncRNA OTUD6B-AS1 in lung adenocarcinoma A549 cells can signifi-cantly inhibit the proliferation,migration,and invasion ability of A549 cells.

ObjectiveTo explore the protective effect and mechanism of Yangxin Dingji capsules on isoproterenol （ISO）-induced ventricular arrhythmia in SD rat cardiomyocytes based on the transforming growth factor-β activated kinase 1 （TAK1）-mitogen-activated protein kinase kinase 3 （MKK3）-p38 mitogen-activated protein kinase （p38 MAPK） signaling pathway. MethodFifty male SPF-grade SD rats were randomly divided into a normal group， a model group， a propranolol group， a low-dose Chinese medicine group， and a high-dose Chinese medicine group. The ventricular arrhythmia model was constructed using the ISO "6+1" method. The propranolol group received propranolol at 0.015 g·kg^-1·d^-1. The Chinese medicine groups received Yangxin Dingji capsules at doses of 0.5、 2 g·kg^-1·d^-1， respectively. The normal and model groups were given an equal volume of 0.9% NaCl solution. Electrocardiogram （ECG） changes in SD rats were recorded using the BL-420F biological function experimental system. Hematoxylin-eosin （HE） staining was used to observe the pathological changes in the heart. Serum levels of cardiac troponin I （cTnI）， creatine kinase-MB （CK-MB）， interleukin-1β （IL-1β）， tumor necrosis factor-α （TNF-α）， and transforming growth factor-β₁ （TGF-β₁） were measured using enzyme-linked immunosorbent assay （ELISA）. The mRNA expression of IL-1β and TNF-α was assessed using real-time fluorescence quantitative polymerase chain reaction （Real-time PCR）. Reactive oxygen species （ROS） expression was detected using immunofluorescence. Protein expression levels of TAK1， phosphorylated TAK1 （p-TAK1）， MKK3， phosphorylated MKK3 （p-MKK3）， p38 MAPK， phosphorylated p38 MAPK （p-p38 MAPK）， nuclear factor-κB （NF-κB）， phosphorylated NF-κB （p-NF-κB）， IL-1β， and TNF-α were measured using Western blot or immunohistochemistry. ResultCompared with normal group， the model group showed significant ventricular arrhythmia in ECG， with an increased arrhythmia score （P<0.01）. Pathological damage to myocardial tissue was evident， and serum levels of cTnI， CK-MB， IL-1β， TNF-α， and TGF-β₁ were elevated （P<0.01）. The mRNA and protein expression of IL-1β and TNF-α in myocardial tissue was also increased （P<0.01）. ROS level and protein expression of p-TAK1， p-MKK3， p-p38 MAPK， and p-NF-κB were elevated in myocardial tissue （P<0.01）. In the propranolol and Chinese medicine groups， the incidence of sustained ventricular tachycardia （SVT） and arrhythmia scores were significantly reduced compared to model group （P<0.05， P<0.01）. Pathological damage to cardiomyocytes was alleviated， and levels of myocardial injury markers and inflammatory factors in serum and myocardial tissue were decreased. The ROS level in myocardial tissue was also reduced （P<0.01）， with a noticeable reduction in related molecules in the p38 MAPK pathway （P<0.05， P<0.01）. ConclusionThe expression of p38 MAPK pathway molecules was up-regulated in myocardial tissue of ISO-induced ventricular arrhythmia rats. Yangxin Dingji capsules may inhibit cardiac inflammation damage by regulating the expression of related molecules in the p38 MAPK pathway， thereby exerting a protective effect on myocardial cells， with TAK1 being a potential target.
