		                        			Esophageal cancer (EC) is a common malignant tumor of the digestive system with an extremely poor prognosis. MicroRNA (miRNA) is an important regulator in tumor occurrence and development, and can participate in malignant biological behaviors such as tumor cell proliferation, invasion, metastasis and apoptosis. Traditional Chinese medicine has the characteristics of accurate curative effects, wide range of effects, and few side effects. The review uses miRNA as the entry point to systematically elaborate on the mechanism of traditional Chinese medicine-mediated miRNA intervening in EC. The results showed that active ingredients of traditional Chinese medicine (including curcumin, Tussilago farfara polysaccharides, Atractylodes macrocephala polysaccharides and ophiopogonin B) and Dougen guanshitong oral liquid could up-regulate the expressions of miRNAs such as miRNA-532-3p (miR-532-3p), miR-551b-3p, miR-99a, miR-34a, miR-199a-3p and miR-377; and the active ingredients/parts of traditional Chinese medicine (including chrysin and Actinidia arguta extract), and Chinese herbal formulas (including Chaihu shugan san combined with Xuanfu daizhe decoction and Modified jupi zhuru decoction) could down-regulate the expressions of miRNAs such as miR-199a-3p, miR-451 and miR-21, which could regulate the expressions of signaling pathways (phosphoinositide 3-kinase/protein kinase B, etc.) or their downstream protein(zinc-finger and homeobox protein 1, etc.) or enzymes(thymidine kinase-1, etc.), inhibit the proliferation, invasion and metastasis of EC cells and induce apoptosis, thereby ultimately achieving the purpose of preventing the disease from aggravating.

		                        			Reflux esophagitis is an inflammatory disease of esophageal mucosa damage caused by the reflux of gastric contents into the esophagus. Its incidence is on the rise, and it has become an important precancerous disease of esophageal cancer. Studies have shown that the continuous inflammatory response stimulates the esophageal mucosa, causing abnormal proliferation of esophageal epithelial cells and damage to esophageal mucosal tissue, which eventually leads to the occurrence of heterogeneous hyperplasia and even carcinogenesis. The nuclear transcription factor-kappa B (NF-κB) signaling pathway is one of the most classical inflammatory and cancer signaling pathways. It has been found that abnormal activation of the NF-κB signaling pathway is crucial to the development and prognosis of reflux esophagitis and esophageal cancer. It is widely involved in the proliferation, autophagy, apoptosis, and inflammatory response of esophageal epithelial cells and tumor cells, accelerating the transformation of reflux esophagitis to esophageal cancer and making it a potential target for the treatment of reflux esophagitis and esophageal cancer. Currently, there is no specific treatment for reflux esophagitis and esophageal cancer, and large side effects often appear. Therefore, finding a promising and safe drug remains a top priority. In recent years, traditional Chinese medicine scholars have conducted a lot of research on NF-κB signaling pathway, and the results indicate that NF-κB signaling pathway is an important potential target for traditional Chinese medicine to prevent and treat reflux esophagitis and esophageal cancer, but there is a lack of comprehensive and systematic elaboration. Therefore, this paper summarized the relevant studies in recent years, analyzed the relationship among NF-κB signaling pathway, reflux esophagitis, esophageal cancer, and transformation from inflammation to cancer, and reviewed the research literature on the regulation of the NF-κB signaling pathway in traditional Chinese medicine to prevent and treat reflux esophagitis and esophageal cancer, so as to provide new ideas for the prevention and treatment of reflux esophagitis and esophageal cancer.

		                        			UPLC-Q-Exactive-MS/MS and network pharmacology were employed to preliminarily study the active components and mechanism of Jinwugutong Capsules in the treatment of osteoporosis. Firstly, UPLC-Q-Exactive-MS/MS was employed to characterize the chemical components of Jinwugutong Capsules, and network pharmacology was employed to establish the "drug-component-target-pathway-disease" network. The key targets and main active components were thus obtained. Secondly, AutoDock was used for the molecular docking between the main active components and key targets. Finally, the animal model of osteoporosis was established, and the effect of Jinwugutong Capsules on the expression of key targets including RAC-alpha serine/threonine-protein kinase(AKT1), albumin(ALB), and tumor necrosis factor-alpha(TNF-α) was determined by enzyme-linked immunosorbent assay(ELISA). A total of 59 chemical components were identified from Jinwugutong Capsules, among which coryfolin, 8-prenylnaringenin, demethoxycurcumin, isobavachin, and genistein may be the main active components of Jinwugutong Capsules in treating osteoporosis. The topological analysis of the protein-protein interaction(PPI) network revealed 10 core targets such as AKT1, ALB, catenin beta 1(CTNNB1), TNF, and epidermal growth factor receptor(EGFR). The Kyoto Encyclopedia of Genes and Genomes(KEGG) enrichment showed that Jinwugutong Capsules mainly exerted the therapeutic effect by regulating the phosphatidylinositol 3-kinase(PI3K)/protein kinase B(AKT) signaling pathway, neuroactive ligand-receptor interaction, mitogen-activated protein kinase(MAPK) signaling pathway, Rap1 signaling pathway and so on. Molecular docking showed that the main active components of Jinwugutong Capsules well bound to the key targets. ELISA results showed that Jinwugutong Capsules down-regulated the protein levels of AKT1 and TNF-α and up-regulated the protein level of ALB, which preliminarily verified the reliability of network pharmacology. This study indicates that Jinwugutong Capsules may play a role in the treatment of osteoporosis through multiple components, targets, and pathways, which can provide reference for the further research.

		                        			Colorectal cancer (CRC) is one of the leading causes of cancer-related deaths worldwide, with increasing incidence and mortality rates. The disease often develops covertly and lacks specific symptoms in its early stages, leading to late-stage diagnoses in most patients. It has become a prominent research topic in the field of digestive system tumors. The exact mechanisms underlying CRC are not yet clear and involve factors such as genetics, gene mutations, inflammatory responses, and aberrant activation of tumor-related signaling pathways. Nuclear factor-kappa B (NF-κB) is a crucial transcription factor that participates in various biological processes, including inflammatory responses, immune responses, cell proliferation, and apoptosis. Research suggests that NF-κB, serving as a molecular link between inflammation and cancer, is highly expressed in CRC. It promotes the occurrence and development of CRC by regulating the activity of target genes such as cell pro-inflammatory factors, chemokines, angiogenic factors, metastasis factors, and anti-apoptotic proteins. Currently, common treatments for CRC include surgery, radiation therapy, and chemotherapy drugs like 5-fluorouracil. However, these treatments have limitations such as significant adverse reactions, high metastasis rates, and the development of drug resistance. Therefore, the search for effective, low-adverse-reaction drugs to replace or supplement current treatments is essential. In recent years, traditional Chinese medicine (TCM) has shown some effectiveness in preventing and treating CRC. TCM has been found to inhibit the growth of CRC cells by modulating the NF-κB signaling pathway, playing a positive role in the occurrence and progression of CRC. Based on the asthenia in origin and sthenia in superficiality and deficiency-excess in complexity in CRC, this article summarized and analyzed the mechanisms and effects of TCM interventions targeting the NF-κB signaling pathway in CRC, and reviewed advances of 10 Chinese medicinal compound formulas and 37 Chinese medicinal monomer components of different types, including flavonoids, phenols, alkaloids, glycosides, and terpenoids with the effects of dispelling pathogenic factors, reinforcing healthy qi, and removing toxins in the prevention and treatment of CRC by targeting the NF-κB pathway. It is found that Chinese medicine can inhibit CRC cell proliferation, invasion, metastasis, angiogenesis, and inflammation by modulating the NF-κB signaling pathway, induce cell apoptosis, restore drug and radiation sensitivity, and counteract CRC. This article is expected to provide insights and references for the in-depth exploration and treatment of CRC mechanisms.

		                        			Objective: This cross-sectional investigation aimed to determine the incidence, clinical characteristics, prognosis, and related risk factors of olfactory and gustatory dysfunctions related to infection with the SARS-CoV-2 Omicron strain in mainland China. Methods: Data of patients with SARS-CoV-2 from December 28, 2022, to February 21, 2023, were collected through online and offline questionnaires from 45 tertiary hospitals and one center for disease control and prevention in mainland China. The questionnaire included demographic information, previous health history, smoking and alcohol drinking, SARS-CoV-2 vaccination, olfactory and gustatory function before and after infection, other symptoms after infection, as well as the duration and improvement of olfactory and gustatory dysfunction. The self-reported olfactory and gustatory functions of patients were evaluated using the Olfactory VAS scale and Gustatory VAS scale. Results: A total of 35 566 valid questionnaires were obtained, revealing a high incidence of olfactory and taste dysfunctions related to infection with the SARS-CoV-2 Omicron strain (67.75%). Females(χ2=367.013, P<0.001) and young people(χ2=120.210, P<0.001) were more likely to develop these dysfunctions. Gender(OR=1.564, 95%CI: 1.487-1.645), SARS-CoV-2 vaccination status (OR=1.334, 95%CI: 1.164-1.530), oral health status (OR=0.881, 95%CI: 0.839-0.926), smoking history (OR=1.152, 95%CI=1.080-1.229), and drinking history (OR=0.854, 95%CI: 0.785-0.928) were correlated with the occurrence of olfactory and taste dysfunctions related to SARS-CoV-2(above P<0.001). 44.62% (4 391/9 840) of the patients who had not recovered their sense of smell and taste also suffered from nasal congestion, runny nose, and 32.62% (3 210/9 840) suffered from dry mouth and sore throat. The improvement of olfactory and taste functions was correlated with the persistence of accompanying symptoms(χ2=10.873, P=0.001). The average score of olfactory and taste VAS scale was 8.41 and 8.51 respectively before SARS-CoV-2 infection, but decreased to3.69 and 4.29 respectively after SARS-CoV-2 infection, and recovered to 5.83and 6.55 respectively at the time of the survey. The median duration of olfactory and gustatory dysfunctions was 15 days and 12 days, respectively, with 0.5% (121/24 096) of patients experiencing these dysfunctions for more than 28 days. The overall self-reported improvement rate of smell and taste dysfunctions was 59.16% (14 256/24 096). Gender(OR=0.893, 95%CI: 0.839-0.951), SARS-CoV-2 vaccination status (OR=1.334, 95%CI: 1.164-1.530), history of head and facial trauma(OR=1.180, 95%CI: 1.036-1.344, P=0.013), nose (OR=1.104, 95%CI: 1.042-1.171, P=0.001) and oral (OR=1.162, 95%CI: 1.096-1.233) health status, smoking history(OR=0.765, 95%CI: 0.709-0.825), and the persistence of accompanying symptoms (OR=0.359, 95%CI: 0.332-0.388) were correlated with the recovery of olfactory and taste dysfunctions related to SARS-CoV-2 (above P<0.001 except for the indicated values). Conclusion: The incidence of olfactory and taste dysfunctions related to infection with the SARS-CoV-2 Omicron strain is high in mainland China, with females and young people more likely to develop these dysfunctions. Active and effective intervention measures may be required for cases that persist for a long time. The recovery of olfactory and taste functions is influenced by several factors, including gender, SARS-CoV-2 vaccination status, history of head and facial trauma, nasal and oral health status, smoking history, and persistence of accompanying symptoms.

		                        			This study aimed to provide data support for resource utilization of the stems and leaves of Astragalus membranaceus var. mongholicus(SLAM) by analyzing and evaluating the chemical constituents. The crude protein, crude fiber, and soluble saccharide of SLAM were analyzed by Kjeldahl method, filtration method, and UV-Vis spectrophotometry, respectively. The nucleosides, amino acids, flavonoids, and saponins of SLAM were analyzed by ultraperformance liquid chromatography-triple quadrupole mass spectrometry(UPLC-TQ-MS). Combined with principal component analysis(PCA), the quality difference of resource components of SLAM was comprehensively evaluated. The results showed that the average content of crude protein, crude fiber, total polysaccharide, and redu-cing sugar in SLAM was 5.11%, 30.33%, 11.03 mg·g~(-1), and 31.90 mg·g~(-1), respectively. Six nucleosides, 15 amino acids, 22 flavonoids, and one saponin were detected, with an average content of 1.49 mg·g~(-1), 6.00 mg·g~(-1), 1.86 mg·g~(-1), and 35.67 μg·g~(-1), respectively. The content of various types of chemical components in SLAM differed greatly in different harvesting periods and growing years. The results of PCA showed that the quality of SLAM produced in Ningxia was superior. The results can provide references for the utilization of SLAM.
