Cancer has become a significant global public health issue， severely impacting public health and societal development. Despite advances in tumor treatment methods in recent years and a gradual decline in cancer mortality rates， drug-related adverse reactions and drug resistance remain substantial challenges. Traditional Chinese medicine （TCM） has demonstrated significant clinical efficacy in cancer treatment and small side effects， making it widely applied in the field of oncology. Xuefu Zhuyutang， derived from Yilin Gaicuo， is known for its abilities to invigorate blood circulation， dispel blood stasis， promote Qi flow， and alleviate pain. It was specifically formulated by the esteemed WANG Qingren of the Qing dynasty for the "blood stasis syndrome in the blood mansion" and is commonly used to treat Qi stagnation and blood stasis syndrome. Clinical studies have shown that Xuefu Zhuyutang， when combined with conventional Western medications， produces significant effects in the treatment of malignant tumors such as liver cancer， lung cancer， and cervical cancer. It substantially reduces the incidence of adverse reactions following Western treatments， including radiation esophagitis， radiation encephalopathy， radiation-induced oral mucositis， and edema. Additionally， it alleviates cancer-related pain and fever， blood hypercoagulability， and associated complications such as depression and anxiety， and also mitigates chemotherapy-induced side effects like hand-foot syndrome. Basic research has demonstrated its potential anti-tumor mechanisms， including the inhibition of Wnt/β-catenin signaling pathway activation， suppression of mitogen-activated protein kinase （MAPK） pathway activation， and anti-tumor angiogenesis. Pharmacological studies have revealed that its active components inhibit tumor cell proliferation and migration， induce tumor cell apoptosis， suppress tumor angiogenesis， enhance the cytotoxicity of natural killer cells against tumors， improve the tumor microenvironment， and regulate immune function. This paper reviewed the latest research progress on Xuefu Zhuyutang in the treatment of malignant tumors from four aspects： theoretical exploration， clinical studies， mechanisms of action， and pharmacological basis， aiming to provide insights and methods for the clinical diagnosis and treatment of malignant tumors.

Objective:To compare the effects of different test meals on postprandial triglycerides and to optimize the standard meal composition and the blood sampling protocol for the oral fat tolerance test.Methods:This study is a prospective, open-label, randomized, cross-over trial. In March 2023, 36 volunteers were recruited in Hebei General Hospital. They underwent a health examination and oral glucose tolerance test. Twenty-six healthy volunteers(11 males and 15 females) were included in this study, with an average age of(39.08±4.56) years. Each volunteer received 75 g protein meal, 75 g fat meal, 700 kcal fixed-calorie high-fat mixed meal, and a high-fat mixed meal with energy adjusted based on 10 kcal/kg body weight. A one-week washout period of regular diet was applied before each trial. Blood was collected at fasting status and 1, 2, 3, 4, 5, and 6 hours after a meal to detect serum triglycerides, total cholesterol, low density lipoprotein-cholesterol(LDL-C), high density lipoprotein-cholesterol(HDL-C), glucose, and insulin. The variations of postprandial metabolic indicators over time following the consumption of different test meals were analyzed. The disparities in postprandial metabolic responses between the two types of mixed meals were compared.Results:The protein meal, fat meal, fixed-calorie high-fat mixed meal, and adjusted-calorie high-fat mixed meal resulted in postprandial triglyceride increases of 22.45%, 115.40%, 77.14%, and 63.63%, and insulin increase of 560.43%, 85.69%, 554.18%, and 598.97%, respectively, and with reductions in total cholesterol, LDL-C, and HDL-C ranging from 5.64%-21.81%, respectively. The blood glucose changed slightly. Changes in metabolic indicators mainly occured within 4 hours. The comparison of the characteristics of postprandial triglycerides between the two high-fat mixed meals showed no statistically significant differences( P>0.05). Conclusion:A standardize protocol with a 700 kcal fixed-calorie high-fat mixed meal as test meal, and blood lipid levels measured at fasting and at 1, 2, 3, and 4 hours after consumption, can serve as an optimized approach for oral fat tolerance test.

Background Adverse drug reactions (ADRs) to sodium dimercaptosulphonate (DMPS) mercury removal treatment have been reported in occupational mercury poisoning. In recent years, the number of cases of mercury poisoning due to mercury-containing cosmetics has been increasing, and ADRs to the use of DMPS are common in clinical practice. Objective To investigate the occurrence of ADRs and the influencing factors in patients with chronic mercury poisoning and mercury exposure treated with DMPS for mercury removal. Methods Patients treated with DMPS due to mercury poisoning at the Occupational Disease Department of Nanjing Prevention and Treatment Center for Occupational Diseases from June 2017 to December 2023 were included in the study. Information on demographics, baseline characteristics, and treatment regimens was collected at admission. Information on secondhand smoke, place of residence, and blood groups not collected at admission was collected in follow-up. The patients were divided into two groups according to whether ADRs occurred after the use of DMPS and were compared for clinical characteristics, and the influencing factors related to the occurrence of ADRs after DMPS treatment were analyzed by binary logistic regression. Results A total of 72 patients were enrolled in the study, of which 26 reported ADRs during mercury removal. A total of 29 ADRs occurred, mainly rash in 11 cases (37.9%), fever in 5 cases (17.2%), and nausea in 4 cases (13.8%). Most ADRs occurred in the second course (7 cases, 26.9%) and the third course (9 cases, 34.6%). Of the 22 non-menopausal women who experienced ADRs, 13 (59.1%) used DMPS in the week prior to menstruation. The logistic regression analysis showed that smoking (OR=27.911, 95%CI: 2.835, 725.809) and blood type O (OR=6.885, 95%CI: 2.014, 26.896) were associated with elevated occurrence of ADRs after DMPS treatment. Conclusions The probability of ADRs after DMPS treatment is not low, but mild presentations are predominant and resolved with immediate treatment, with a favourable prognosis. The O blood group, smoking individuals, and female patients using DMPS one week before menstruation may be more prone to ADRs.

This article explores the interaction between aspirin and safflower yellow injection from the perspective of pharmacokinetics, combined with pharmacological indicators such as anticoagulation. Quantitative HPLC analysis was performed for the detection of salicylic acid in plasma samples, and the pharmacokinetic effects of aspirin in combination with safflower yellow injection on aspirin’s hydrolyzed product salicylic acid was evaluated. Thromboxane B2 (TXB2) and 6-keto prostaglandin F1 in plasma were determined using enzyme-linked immunosorbent assay and fully automated biochemical analyzer α (6-keto-PGF1) α）, and the levels of aspartate aminotransferase (AST), alanine aminotransferase (ALT), blood urea nitrogen (BUN), and serum creatinine (Scr) were tested to evaluate the anticoagulant effect and safety indicators after long-term combined use of the two drugs, including liver and kidney function and cardiac pathological examination. The results showed that, compared with the aspirin group, there was no significant difference (P>0.05) in the plasma pharmacokinetic parameters of rats with combined use of safflower yellow injection. In addition, the plasma TXB2 in the combination group was significantly reduced compared to the aspirin group (P<0.01), yet with no significant difference for 6-keto-PGF1 α (P>0.05). There was no statistically significant difference in the levels of serum BUN, Scr, AST, and ALT between the two groups before and after treatment (P>0.05). These results suggest that the combination of aspirin and safflower yellow injection does not cause significant change in the blood concentration of salicylic acid. It does not affect the antiplatelet effect of aspirin.

Objective To investigate the effects of circ_UBE2C on the proliferation and glycolysis of lung cancer cells and its mechanism of action.Methods The expression of circ_UBE2C,miR-107,and hexokinase 2(HK2)in lung cancer tissues and normal lung tissues were analyzed based on the The Cancer Genome Atlas(TCGA)database.Kaplan-Meier survival curve was plotted to analyze the correlation between circ_UBE2C/miR-107/HK2 expression and survival of the lung cancer patients.qRT-PCR was used to detect the expression of circ_UBE2C and miR-107,and Western blotting was employed to measure the expression of HK2 and PCNA in human normal lung epithelial cells(BEAS-2B)and human lung cancer cell lines(A549,NCI-H460,and NCI-H1299).Then A549 and NCI-H1299 cells were divided into the blank group(NC),circ_UBE2C knockdown group(si-circ),HK2 knockdown group(si-HK2),simultaneous knockdown of miR-107+HK2 group(miR-inhibitor+si-HK2),and simultaneous knockdown of circ_UBE2C+miR-107 group(si-circ+miR-inhibitor).CCK-8 assay and colony formation assay were employed to measure the proliferation of above cell groups.The glucose uptake,lactate generation,and ATP production in the cells were measured by glucose uptake colorimetric assay kit,lactic acid detection kit,and ATP content determination kit,respectively.Seahorse XF glycolytic stress test and Seahorse XF cellular mitochondrial stress test were respectively performed to detect the extracellular acidification ratio(ECAR)and cellular oxygen consumption ratio(OCR).The targeting relationship between the circ_UBE2C and miR-107,and miR-107 and HK2 was validated by dual-luciferase reporter gene assay.Results Compared with normal lung tissues,the expression of circ_UBE2C and HK2 was up-regulated,while that of miR-107 was down-regulated in lung cancer tissues(P＜0.05).The expression of circ_UBE2C and HK2 was elevated,and that of miR-107 was reduced in A549 and NCI-H1299 cells when compared with BEAS-2B cells(P＜0.05).Survival analysis showed that the patients with high expression of circ_UBE2C and HK2 or low expression of miR-107 had shorter survival(P＜0.05).Compared with the NC group,both si-circ and si-HK2 resulted in significantly reduced proliferation,glucose uptake,lactate generation,ATP production,and ECAR and OCR values in A549 and NCI-H1299 cells(P＜0.05).Dual luciferase reporter gene assay confirmed that circ_UBE2C could directly bind to and negatively regulate miR-107 expression.HK2 was then identified as a downstream target of miR-107.Compared with the si-HK2 group,the proliferative ability and glycolysis level of A549 and NCI-H1299 cells were significantly increased in the miR-inhibitor+si-HK2 group and the si-circ+miR-inhibitor group.Conclusion Knockdown of circ_UBE2C significantly suppresses the proliferation and glycolysis of lung cancer cells via targeting up-regulation of miR-107 and then exerting inhibitory effect on HK2 expression.

Objective:To investigate the efficacy of a combined model constructed by the radiomics features based on non-contrast CT (NCCT) combined with clinical risk factors in predicting the occurrence of symptomatic intracranial hemorrhagic transformation (sICH) after intravenous thrombolysis with recombinant tissue plasminogen activator (rt-PA) in patients with anterior circulation acute ischemic stroke (AIS).Methods:In this cross-sectional study, clinical and imaging data of 316 patients with anterior circulation AIS who received intravenous thrombolysis with rt-PA at Nantong First People′s Hospital from October 2018 to September 2022 were retrospectively analyzed. The cases were divided into a training set of 210 cases and a validation set of 106 cases by stratified random sampling at a ratio of 7∶3. Univariate and multivariate logistic regression analyses were performed to select the independent clinical risk factors for predicting sICH. The infarct area was delineated on the NCCT images and radiomics features were extracted. The extracted radiomics features were dimensionally reduced and selected using the inter-and intra-group correlation coefficients, maximum correlation and minimum redundancy, and the least absolute shrinkage and selection operator, and then the radiomics score was calculated. Finally, multivariate logistic analysis was performed and the clinical risk factors and radiomics scores were used to establish the clinical model, the radiomics model and the radiomics-clinical combined model. The predictive efficacy of each model was evaluated by the receiver operating characteristic curve and the area under the curve, and decision curve analysis (DCA) was used to calculate and quantify the net benefits of each predictive model.Results:In total eight radiomics features were selected to construct the radiomics model. Multivariate logistic analysis showed that hypertension ( OR=2.703, 95% CI 1.153-6.334, P=0.022), atrial fibrillation ( OR=3.023, 95% CI 1.290-7.085, P=0.011), and the National Institutes of Health Stroke Scale score at admission ( OR=1.078, 95% CI 1.017-1.143, P=0.012) were independent risk factors for sICH after rt-PA intravenous thrombolysis in patients with anterior circulation AIS. In the validation set, the area under the curve of the combined model for predicting sICH was 0.763 (95% CI 0.618-0.909), which was higher than that of the clinical model 0.710 (95% CI 0.552-0.868) and the radiomics model 0.708 (95% CI 0.568-0.848). DCA showed that the combined model could allow patients to obtain higher net benefits. Conclusion:The combined model constructed based on the radiomics of NCCT and clinical risk factors has a high diagnostic efficacy in predicting sICH after rt-PA intravenous thrombolysis in patients with anterior circulation AIS.

Objective:To compare the self-evaluated learning behavior and achievement of eight-year-program clinical medical students on online and offline problem-based learning (PBL), and to provide references and suggestions for successful implementation of online PBL teaching.Methods:During the three semesters of September 2020 to January 2022, a survey was performed on 100 clinical medical students of 2018 eight-year program on online or offline PBL teaching in Xiangya School of Medicine, Central South University. At the end of PBL courses, the students received questionnaires to self-assess their learning behavior and achievement in online or offline PBL teaching. The data were analyzed using the paired rank sum test with the use of SPSS 26.0.Results:Before class, there were no significant differences in learning behaviors including preparation time, communication with classmates, and materials collecting and sorting between students on online and offline PBL teaching ( P>0.05). In class, no significant differences were found in students' initiative of speaking and degree of satisfaction with classmates' speaking between online and offline teaching ( P>0.05), but the students on offline teaching showed significantly better concentration of attention ( Z=-4.24, P<0.001), listening to classmates' speeches ( Z=-3.42, P=0.001), and classmates' interaction ( Z=-3.11, P=0.002) compared with those on online teaching. No significant differences were observed between online and offline PBL teaching in students' self-evaluated learning achievements including improvements in autonomous learning ability, problem-solving ability, and literature inquiry skills ( P>0.05). Conclusion:Students on online PBL teaching have generally as good pre-class preparation and in-class learning performance as those on offline PBL teaching, indicating that the online PBL mode can be well implemented, and it can also ensure almost the same learning achievement as offline teaching.

ObjectiveTo collect and analyze the properties and application characteristics of external use of roots and rhizomes of Chinese herbal medicines in the Chinese Materia Medica（《中华本草》） to provide data references for the research on clinical external use of Chinese medicine， in order to provide data reference for clinical external use of traditional Chinese medicine（TCM）. MethodThe Chinese herbal medicines included in the Chinese Materia Medica were systematically screened. The inclusion criterion was the explicit mention of terms like "root", "rhizome", "root bark", "tuber", "tuberous root", etc. under the "Source" in the Chinese Materia Medica. Information on properties, flavors, meridian tropism, medicinal parts, fresh use, toxicity, efficacies and indications, and dosage of roots and rhizomes of Chinese herbal medicines was collected. The information was then entered into an Excel spreadsheet for statistical analysis. ResultThe Chinese Materia Medica records 2 662 roots and rhizomes of Chinese herbal medicines, of which 1 653 are suitable for external use. The predominant properties and flavors are cool, cold, bitter, pungent, and sweet. These Chinese herbal medicines mainly act on the liver, lung, and spleen meridians. The primary medicinal parts used include root, rhizome, and root bark. More than half of the roots and rhizomes of Chinese herbal medicines can be used in their fresh form. The main efficacies include clearing heat, removing toxins, resolving stasis, dispersing accumulation, resolving blood stasis and stopping bleeding, reducing swelling and alleviating pain, dispelling dampness and relieving pain. The main indications are skin sores, traumatic injuries, and rheumatic diseases. Common external application methods include poultice, decoction for washing, and applying powdered form. Most of these Chinese herbal medicines lack specific dosage guidelines for external use, with an emphasis on using an appropriate amount. ConclusionThe Chinese Materia Medica contains a wide range of roots and rhizomes of Chinese herbal medicines suitable for external use, with definite therapeutic effects, providing a broad perspective for the application of Chinese medicine externally. However, there are still problems such as unclear dosages and limited research. Further studies are necessary to better utilize the advantages of the external use of Chinese medicine.
