Objective:To analyze the malignant probability of thyroid nodules with the diagnosis of atypia of undetermined significance or follicular lesion of undetermined significance (AUS/FLUS) determined by fine-needle aspiration (FNA) and to explore the value of the combined application of BRAFV600E gene detection for the diagnosis of benign and malignant thyroid nodules. Methods:A total of 114 patients including 20 males and 94 females, aged 16-76 years old with thyroid nodules underwent FNA examination and surgical treatment in the Affiliated Cancer Hospital of Zhengzhou University from October 2018 to November 2019 were retrospectively analyzed. Postoperative histopathological results were used as the gold standard for the diagnosis of malignant thyroid nodules. The malignant rate of thyroid nodules with the diagnosis of AUS/FLUS was evaluated. Differential diagnostic efficacy of preoperative FNA combined with BRAFV600E gene detection for papillary thyroid carcinoma (PTC) was analyzed by McNemer test and diagnostic test evaluation method. Results:The mutation rate of BRAFV600E gene was 84.76% (89/105) in PTC. PTC accounted for 57.14% (12/21) of the patients with the diagnoses of AUS/FLUS determined by FNA. The specificity, sensitivity, positive predictive value and negative predictive value of BRAFV600E mutation examination for the diagnosis of malignant thyroid nodules determined preoperatively as AUS/FLUS were 9/9, 5/12, 5/5 and 9/16, respectively. BRAFV600E mutation examination could improve the detection rate of PTC in patients with AUS/FLUS ( OR=0.438, 95% CI=0.251-0.763, P=0.016). Conclusion:FNA combined with BRAFV600E mutation examination can significantly improve the detection rate of malignant thyroid nodules diagnosed preoperatively as AUS/FLUS.

OBJECTIVES:
To determine the potential molecular mechanisms underlying the therapeutic effect of curcumin on hepatocellular carcinoma (HCC) by network pharmacology and experimental in vitro validation.
METHODS:
The predictive targets of curcumin or HCC were collected from several databases. the identified overlapping targets were crossed with Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) analyses using the Database for Annotation, Visualization, and Integrated Discovery (DAVID) platform. Two of the candidate pathways were selected to conduct an experimental verification. The 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide tetrazolium (MTT) assay was used to determine the effect of curcumin on the viability of HepG2 and LO2 cells. The apoptosis and autophagy of HepG2 cells were respectively detected by flow cytometry and transmission electron microscopy. Besides, western blot and real-time polymerase chain reaction (PCR) were employed to verify the p53 apoptotic pathway and adenosine 5'-monophosphate (AMP)-activated protein kinase (AMPK) autophagy pathway. HepG2 cells were pretreated with pifithrin-α (PFT-α) and GSK690693 for further investigation.
RESULTS:
The 167 pathways analyzed by KEGG included apoptosis, autophagy, p53, and AMPK pathways. The GO enrichment analysis demonstrated that curcumin was involved in cellular response to drug, regulation of apoptotic pathway, and so on. The in vitro experiments also confirmed that curcumin can inhibit the growth of HepG2 cells by promoting the apoptosis of p53 pathway and autophagy through the AMPK pathway. Furthermore, the protein and messenger RNA (mRNA) of the two pathways were downregulated in the inhibitor-pretreated group compared with the experimental group. The damage-regulated autophagy modulator (DRAM) in the PFT-α-pretreated group was downregulated, and p62 in the GSK690693-pretreated group was upregulated.
CONCLUSIONS
Curcumin can treat HCC through the p53 apoptotic pathway and the AMPK/Unc-51-like kinase 1 (ULK1) autophagy pathway, in which the mutual transformation of autophagy and apoptosis may occur through DRAM and p62.

OBJECTIVE
To confirm the therapeutic effect of Jintiange capsules on osteoarthritis(OA) and the potential mechanism of synovial mesenchymal stem cell exosomes(SMSC-Exos) and articular chondrocytes(ACs) in the treatment of OA based on high-throughput sequencing technology.
METHODS
Type Ⅱ collagenase-induced OA rats were used for efficacy verification through general behavioral observation, bipedal balance difference experiment, mechanical foot reflex threshold, Micro-CT observation, and Safranin O-Fast Green staining. SMSCs and ACs were cultured in suitable concentration of drug-containing serum, and mRNA sequencing was performed on ACs in the control, model, and Jintiange capsules groups, as well as miRNA sequencing on SMSC-Exos. Differential expressed mRNAs and miRNAs were screened and target genes were predicted. The common differential expressed genes between SMSC and ACs were obtained by intersecting the differential expressed genes, and a miRNA-mRNA regulatory network was constructed using Cytoscape software. The expression trend analysis of common differential expressed genes was conducted, as well as the correlation analysis between differential expressed gene mRNA and miRNA, Micro-CT efficacy indicators, and differential expressed gene mRNA.
RESULTS
Under the pathological state of OA, the expression of miRNA-23a-3p, miRNA-342-3p, miRNA-146b-5p, miRNA-501-3p, and miRNA-214-3p were down-regulated, while miRNA-222-3p, miRNA-30e-3p, miRNA-676-3p, and miRNA-192-5p were up-regulated (P<0.05). The expressions of these miRNAs were significantly reversed after intervention with drug-containing serum of Jintiange capsules. There was a certain correlation between Micro-CT efficacy indicators, mRNA and miRNA.
CONCLUSION
Jintiange capsule has obvious efficacy in the treatment of OA, and its mechanism may be related to the promotion of SMSC-Exos targeting ACs to transport miRNA and then regulate Serpinb10, Ntn1, Il1b, Tgm2, Megf10, Il11, Cd40, Slc15a3, Pou2f2 and other genes.

OBJECTIVE To optimize the heart-nourishing granule extraction process by network pharmacology and Box-Behnken response surface method. METHODS The active ingredients of heart-nourishing granule were excavated through network pharmacology and their mechanism of action in the treatment of coronary heart disease was preliminarily explored. Molecular docking technology was used to predict the binding ability of the active ingredients to the main targets. At the same time, based on the compatibility relationship between the monarch, minister, assistant and guide of the prescription, the pharmacological effects of the ingredients, and the content determination index components of each medicinal flavor in the 2020 edition of the Chinese Pharmacopoeia, the process evaluation index components of heart-nourishing granule were further determined. In addition, combined with the analytic hierarchy process to determine the weight of each component, the Box-Behnken response surface method was used to optimize the extraction process of heart-nourishing granule. RESULTS The main active components of heart-nourishing granule screened were catalpol, Rhmannioside D, acteoside, ferulic acid and lobetyolin. By acting on core targets such as AKT1, IL-6, IL-1b, VEGFA, JUN and MAPK3, they regulated lipid and atherosclerosis, MAPK signaling and other pathways played a role in the treatment of coronary heart disease. Molecular docking results showed that the binding energies of active components and core targets predicted by network pharmacology were all < -5.0 kJ·mol-1. Five components catalpol, Rhmannioside D, acteoside, ferulic acid and lobetyolin were calculated by analytic hierarchy process method. The weight coefficients of arginyl glycosides were 0.329 7, 0.329 7, 0.164 8, 0.109 9, and 0.065 9, respectively. The Box-Behnken response surface method obtained the optimal water extraction process: 10 times the amount of water was used to extract twice, and each time was decocted for 1.5 h. The verification test showed that the contents of the five components were consistent with the predicted values, and the RSD values were all <5%. CONCLUSION The extraction process of heart-nourishing granule based on network pharmacology and Box-Behnken response surface methodology is stable and feasible, which provided an experimental basis for its further quality improvement.
