Lung cancer is the leading cause of cancer-related deaths worldwide, and tumor metastasis is a key factor contributing to the mortality of most lung cancer patients. Aberrant activation of epithelial-mesenchymal transition (EMT) is a major driver of lung cancer progression and metastasis. EMT is characterized by the loss of apical-basal polarity and intercellular adhesion in highly differentiated, polarized, and organized epithelial cells, which acquire motility, migratory potential, and invasive properties. During this process, cells undergo cytoskeletal remodeling and transform into a mesenchymal phenotype, accompanied by associated changes in cellular markers. The EMT process is highly complex and is tightly regulated by intricate networks involving multiple transcription factors, post-translational controls, epigenetic modifications, and non-coding RNAs. Therefore, therapies targeting the mechanisms of malignant transformation and their associated pathways in lung cancer are of significant clinical importance. In recent years, EMT has attracted increasing attention as a potential target for cancer therapy. Chinese medicine, with its characteristics of multi-target action, low side effects, and good therapeutic efficacy, has demonstrated an important role in anticancer treatment. A series of studies have investigated the role of Chinese medicine in inhibiting EMT in lung cancer. Active ingredients of Chinese medicine, including flavonoids, glycosides, phenols, terpenoids, saccharides, and alkaloids, as well as Chinese medicine compound formulas, have shown significant regulatory effects on EMT. Their mechanisms mainly involve multiple pathways, targets, and links, including signaling pathways, exosomes, microRNAs (miRNAs), and the tumor-associated immune microenvironment. This article summarizes the mechanisms by which EMT promotes malignant tumor progression and reviews the current research on how Chinese medicine active ingredients, monomers, and compound formulas inhibit EMT and suppress lung cancer cell migration and invasion. This study is expected to provide comprehensive theoretical information for basic and translational research on lung cancer.

ObjectiveTo investigate the effect and mechanism of polysaccharide in water extract of Cyclocarya paliurus (CPWP) in inhibiting benign prostatic hyperplasia (BPH). MethodsCPWP was obtained by heating reflux, aqueous extraction, alcohol precipitation, and freeze drying. The chemical composition and structural properties of CPWP were analyzed by high performance liquid chromatography with 1-pheny-3-methyl-5-pyrazolone pre-column derivatization and infrared spectroscopy. Male SD rats were randomly assigned into control, model, finasteride (ig 5 mg·kg-1), and low-, medium-, and high-dose (ig 50, 75, 100 mg·kg-1) CPWP groups, with 8 rats in each group. The BPH model was established by subcutaneously injecting propionate testosterone in castrated rats. The rats in the drug intervention groups were administrated with corresponding drugs, and those in the control group were administrated with an equal volume of normal saline each day. After 30 consecutive days, the rats were sacrificed, and the prostate tissue was separated and weighed. The effects of drug interventions on the body weight, prostate wet weight, and prostate index of rats were examined. The prostate tissue was stained with hematoxylin-eosin (HE) for observation of pathological changes. Enzyme-linked immunosorbent assay was employed to measure the level of dihydrotestosterone (DHT), and immunohistochemical staining was used to detect the expression of steroid 5 alpha-reductase 2 (SRD5A2) and Ki67 in the prostate tissue. ResultsCPWP was identified as a saccharide, with characteristic absorption peaks of saccharides. CPWP showed the total sugar content of 44.15% and molecular weight within the range of 5.5-78.8 kDa, being composed of mannose, rhamnose, galacturonic acid, glucose, galactose, xylose, and arabinose. Compared with the control group, the model group had significantly increased prostate wet weight and prostate index (P<0.01), thick and tall prostate epithelial cells, increased internal wrinkles, papillary expansion into the cavity, an elevation in DHT level in the serum, and up-regulated expression of SRD5A2 and Ki67 in the prostate tissue (P<0.05, P<0.01). Compared with the model group, both the finasteride and CPWP groups showed decreases in prostate wet weight and prostate index (P<0.05, P<0.01), thinned prostate epithelial cells, with only a small portion of internal wrinkles and papillary expansion into the cavity, shortened papillary protrusions, lowered DHT level in the serum, and down-regulated expression of SRD5A2 and Ki67 in the prostate tissue (P<0.01). Moreover, CPWP exerted effects in a dose-dependent manner. ConclusionCPWP inhibits BPH by regulating the expression of SRD5A2.

The abnormal accumulation of neutrophil extracellular traps (NETs) can promote the initiation and progression of pancreatic cancer, which is considered a potential therapeutic target for this disease. The Miraculous Pivot·Inquiry About Statement (《灵枢·口问》) have recorded the concept of "defensive qi stagnation". Based on the recognition that the function of defensive qi is similar to the immune function of neutrophils, and combining traditional Chinese medicine theory with clinical practice, it is proposed that the abnormal accumulation of NETs may be a pathological product of "defensive qi stagnation", with the spleen being the critical site of pathology. Further exploring the application strategy of cleaning spleen and restoring defensive qi method in pancreatic cancer treatment, it is proposed to employ three approaches such as dredging method to eliminate spleen stagnation and inhibit pancreatic cancer proliferation, cleaning method to remove spleen dampness and suppress the inflammatory micro-environment, and tonifying method to strengthen Weiqi and to improve the immune microenvironment, which aims to provide new insights for the clinical treatment of pancreatic cancer with traditional Chinese medicine.

BACKGROUND:Studies have shown that patients with premature ovarian failure have changes in the structure of intestinal flora and that imbalance of intestinal microbiota may be one of the important mechanisms in the development of premature ovarian failure. OBJECTIVE:To investigate the effect of Liuwei Dihuang Wan on oxidative stress and intestinal microbiota in premature ovarian failure mice induced by cyclophosphamide. METHODS:Forty-five female ICR mice were randomized into three groups:blank group(normal mice),model group(premature ovarian failure mice),and Liuwei Dihuang Wan group.A mouse model of premature ovarian failure was prepared by one-time intraperitoneal injection of cyclophosphamide(120 mg/kg)in the latter two groups.After successful modeling,the Liuwei Dihuang Wan group was intragastrically administered for 28 continuous days,and the other two groups were intragastrically administered with the same amount of normal saline for 28 days.Mouse body mass was recorded weekly and ovarian index was calculated.The development of mouse follicles was observed using hematoxylin-eosin staining.ELISA method was used to detect serum levels of anti-Mullerian hormone,estradiol,follicle stimulating hormone,superoxide dismutase,glutathione peroxidase,and malondialdehyde.Meanwhile,the gut microbiome of all mice was detected through 16S rDNA sequencing. RESULTS AND CONCLUSION:The mice in the model group had loose hair,decreased vigor and grip strength,almost no increase in body mass,and decreased ovarian index.Whereas,the mouse body mass and ovarian index were increased after treatment with Liuwei Dihuang Wan(P<0.05).The estrous cycle of mice in the model group was disorganized;Liuwei Dihuang Wan could restore the estrous cycle and reduce the number of atretic follicles in mice with premature ovarian failure.The serum levels of follicle stimulating hormone and malondialdehyde in the model group significantly increased(P<0.01),while the levels of estradiol,anti-Mullerian hormone,superoxide dismutase,and glutathione peroxidase significantly decreased(P<0.01).Liuwei Dihuang Wan could significantly decrease the serum levels of follicle stimulating hormone and malondialdehyde(P<0.01),and increase the levels of estradiol,anti-Mullerian hormone,superoxide dismutase,and glutathione peroxidase.According to the 16S rDNA sequencing results,Liuwei Dihuang Wan could regulate the abundance and diversity of intestinal microbiota,and increase the relative abundance of beneficial bacteria.KEGG pathway analysis showed that the intestinal microbiota and metabolic pathways,biosynthesis of secondary metabolites,microbial metabolism in different environments,and biosynthesis of amino acids were regulated by Liuwei Dihuang Wan.To conclude,the changes in the structure of intestinal microbiome may be one of the potential mechanisms of Liuwei Dihuang Wan in treating premature ovarian failure.Liuwei Dihuang Wan can regulate the structure of intestinal microbiome,increase the number of beneficial bacteria,reduce the number of harmful bacteria,and thus improve the balance of intestinal microbiota.This regulatory effect helps to reduce oxidative stress levels and further inhibit ovarian oxidative stress in mice with premature ovarian failure.

BACKGROUND:More and more animal experiments and clinical studies have confirmed that electrical stimulation can promote the repair of peripheral nerve injury,but the specific mechanism is not yet fully understood. OBJECTIVE:To investigate the effect of electrical stimulation-induced miR-741-3p regulating Radil on Schwann cell migration. METHODS:(1)Twelve male SD rats were randomly divided into electrical stimulation group and control group.The electrical stimulation group received continuous electrical stimulation for 7 days after sciatic nerve compression injury,while the control group was not treated after sciatic nerve compression.The injured nerves were taken on day 7 after operation.The expression difference of miR-741-3p between the two groups was verified by fluorescence in situ hybridization.(2)The target genes of miR-741-3p were predicted by miRDB,TargetScan,and miRWalk databases.(3)Schwann cells were transfected with miR-741-3p mimetic and its control,miR-741-3p inhibitor and its control,Radil siRNA and its control,miR-741-3p inhibitor+Radil siRNA and miR-741-3p inhibitor+siRNA control.The transfection efficiency was detected by RT-PCR.The migration ability of Schwann cells was detected by Transwell chamber. RESULTS AND CONCLUSION:(1)The fluorescence intensity of miR-741-3p in the electrical stimulation group was lower than that in the control group.(2)The results of database prediction showed that 69 genes might be the target genes of miR-741-3p.Radil was one of the predicted target genes,which was mainly involved in cell adhesion and migration.(3)Compared with the miR-741-3p inhibitor control group,the number of Schwann cell migration increased in the miR-741-3p inhibitor group(P<0.05).Compared with the miR-741-3p mimic control group,the number of Schwann cell migration in the miR-741-3p mimic group decreased(P<0.05).Compared with the siRNA control group,the number of Schwann cell migration was decreased in the Radil siRNA group(P<0.05).(4)Compared with miR-741-3p inhibitor control group,the expression level of Radil was increased in miR-741-3p inhibitor group.Compared with miR-741-3p mimic control group,the expression level of Radil was decreased in miR-741-3p mimic group.(5)Compared with miR-741-3p inhibitor+siRNA control group,the number of Schwann cell migration was reduced in miR-741-3p inhibitor+Radil siRNA group(P<0.05).The results showed that electrical stimulation promoted the migration of Schwann cells by down-regulating miR-741-3p and targeting Radil gene.

Objective To establish and internally validate a predictive model for poorly differentiated adenocarcinoma based on CT imaging and tumor marker results. Methods Patients with solid and partially solid lung nodules who underwent lung nodule surgery at the Department of Thoracic Surgery, the Affiliated Brain Hospital of Nanjing Medical University in 2023 were selected and randomly divided into a training set and a validation set at a ratio of 7:3. Patients' CT features, including average density value, maximum diameter, pleural indentation sign, and bronchial inflation sign, as well as patient tumor marker results, were collected. Based on postoperative pathological results, patients were divided into a poorly differentiated adenocarcinoma group and a non-poorly differentiated adenocarcinoma group. Univariate analysis and logistic regression analysis were performed on the training set to establish the predictive model. The receiver operating characteristic (ROC) curve was used to evaluate the model's discriminability, the calibration curve to assess the model's consistency, and the decision curve to evaluate the clinical value of the model, which was then validated in the validation set. Results A total of 299 patients were included, with 103 males and 196 females, with a median age of 57.00 (51.00, 67.25) years. There were 211 patients in the training set and 88 patients in the validation set. Multivariate analysis showed that carcinoembryonic antigen (CEA) value [OR=1.476, 95%CI (1.184, 1.983), P=0.002], cytokeratin 19 fragment antigen (CYFRA21-1) value [OR=1.388, 95%CI (1.084, 1.993), P=0.035], maximum tumor diameter [OR=6.233, 95%CI (1.069, 15.415), P=0.017], and average density [OR=1.083, 95%CI (1.020, 1.194), P=0.040] were independent risk factors for solid and partially solid lung nodules as poorly differentiated adenocarcinoma. Based on this, a predictive model was constructed with an area under the ROC curve of 0.896 [95%CI (0.810, 0.982)], a maximum Youden index corresponding cut-off value of 0.103, sensitivity of 0.750, and specificity of 0.936. Using the Bootstrap method for 1000 samplings, the calibration curve predicted probability was consistent with actual risk. Decision curve analysis indicated positive benefits across all prediction probabilities, demonstrating good clinical value. Conclusion For patients with solid and partially solid lung nodules, preoperative use of CT to measure tumor average density value and maximum diameter, combined with tumor markers CEA and CYFRA21-1 values, can effectively predict whether it is poorly differentiated adenocarcinoma, allowing for early intervention.

ObjectiveTo investigate the role of silent information regulatory protein (SIRT6)/hypoxia-inducible factor-1α (HIF-1α) pathway in regulating the reprogramming of glucose metabolism in ulcerative colitis (UC) and the mechanism of intervention of Shaoyaotang. MethodsForty-eight c57bL/6 mice were randomly divided into a blank group, a model group, a Mesalazine group (0.42 g·kg-1), a Shaoyaotang group (31.08 g·kg-1), an inhibitor group (OSS-128167, 50 mg·kg-1), and an inhibitor + Shaoyaotang group (50 mg·kg-1 OSS-128167 + 31.08 g·kg-1 Shaoyaotang). A UC model was established by the administration of 2.5% dextran sulfate sodium (DSS) solution for mice in other groups for 7 d, except for the blank group. The mice in each group were treated with saline, Mesalazine, Shaoyaotang, inhibitor, and inhibitor + Shaoyaotang, respectively, for 7 d. The mice were necropsied 24 h after the last administration of the drug. The blood was collected from the orbital region, and colon tissue was taken. Hematoxylin-eosin (HE) staining was used to observe the pathological changes in colon tissue. Enzyme-linked immunosorbent assay (ELISA) was employed to detect serum interleukin (IL)-10, IL-17, and IL-6 levels. A biochemical method was used to detect glucose and lactate dehydrogenase A (LDHA) levels. Immunohistochemistry (IHC) was employed to detect IL-22 and transforming growth factor-β1 (TGF-β1) levels in colon tissue, and Western blot and real-time fluorescence quantitative polymerase chain reaction (Real-time PCR) were used to detect relative protein and mRNA expressions of SIRT6, HIF-1α, and LDHA. ResultsCompared with those of the blank group, disease activity index (DAI) scores of mice in the model group and inhibitor group were significantly increased (P<0.01). The length of colon tissue was significantly shortened, and colon tissue was congested and eroded. The pathohistological scores were significantly increased (P<0.01). The levels of serum inflammatory factors IL-17 and IL-6 were significantly elevated, and the levels of IL-10 were significantly decreased (P<0.01). The protein expressions of IL-22 and TGF-β1 were significantly reduced in colon tissue (P<0.01). The relative protein and mRNA expressions of SIRT6 were significantly decreased (P<0.01), and the relative protein and mRNA expressions of HIF-1α and LDHA and the contents of glucose and lactate were significantly elevated (P<0.01). The level of inflammation in the colon of the mice in the inhibitor group was more severe than that in the model group (P<0.01). Compared with the model group, the Mesalazine group, the Shaoyaotang group, and the inhibitor + Shaoyaotang group showed reduced colonic injury, significant decrease in serum IL-17 and IL-6, significant increase in IL-10 (P<0.01), significant increase in the protein expressions of IL-22 and TGF-β1 in colon tissue (P<0.01), significant increase in the protein expressions of SIRT6 and the relative mRNA expressions (P<0.01), and significant reduction in the protein expressions of HIF-1α and LDHA, the relative mRNA expressions, and the contents of glucose and lactate (P<0.01). Compared with those in the Shaoyaotang group, the serum IL-17 and IL-6 were significantly increased, and IL-10 was significantly decreased in the inhibitor + Shaoyaotang group (P<0.01). The protein expressions of IL-22 and TGF-β1 in colon tissue were significantly decreased (P<0.01). The expressions of SIRT6 protein and the relative mRNA expressions were significantly decreased (P<0.01). The protein expressions of HIF-1α and LDHA, the relative mRNA expressions, and the contents of glucose and lactate were significantly elevated (P<0.01). However, the difference between the Shaoyaotang group and the Mesalazine group was not significant. ConclusionShaoyaotang can effectively treat DSS-induced mice with UC through the SIRT6/HIF-1α pathway, and its mechanism of action may be related to the regulation of the SIRT6/HIF-1α pathway and glucose metabolism reprogramming and the inhibition of glycolysis.

ObjectiveTo investigate the effect of Shaoyaotang on T helper cell 17/regulatory T lymphocyte(Th17/Treg) cell balance in ulcerative colitis and decipher the intervention mechanism based on glucose metabolism reprogramming. MethodsThe mouse model of ulcerative colitis was established by the dextran sulfate sodium (DSS) method. Forty-eight C57BL/6 mice were randomly allocated into normal, model, Western drug control (mesalazine, 0.39 g·kg-1·d-1), Shaoyaotang (15.54 g·kg-1·d-1), inhibitor (2-deoxy-D-glucose, 2-DG, 100 mg·kg-1·d-1), and inhibitor (2-DG, 100 mg·kg-1·d-1) + Shaoyaotang (15.54 g·kg-1·d-1) groups. Mice were administrated with the corresponding drugs by gavage for 7 days. The general conditions and the colon injury degree were observed 24 h after the last administration. The expression of interleukin (IL)-10 and IL-17 in the colon tissue was detected by immunohistochemical staining. Western blot and Real-time fluorescence quantitative polymerase chain reaction (Real-time PCR) were performed to determine the protein and mRNA levels, respectively, of hypoxia-inducing factor-1α (HIF-1α), lactate dehydrogenase (LDHA), and hexokinase 2 (HK2) in the colon tissue. Th17/Treg cell differentiation was detected by flow cytometry. Enzyme-linked immunosorbent assay was employed to measure the levels of lactic acid and glucose in the colon tissue and IL-10, IL-17, and IL-6 in the serum. ResultsCompared with the normal group, the model group showed decreases in body weight and disease activity index (DAI) (P<0.05), elevations in levels of HIF-1α, LDHA, HK2, IL-17, IL-6, Th17 cells, lactic acid, and glucose in the colon tissue (P<0.05), and declines in the levels of of IL-10 and Treg cells (P<0.05). Compared with the model group, the drug administration groups showed increases in body weight and DAI (P<0.05), declines in levels of HIF-1α, LDHA, HK2, IL-17, IL-6, Th17 cells, lactic acid, and glucose in the colon tissue (P<0.05), and rises in levels of IL-10 and Treg cells (P<0.05). Shaoyaotang+2-DG group had the most obvious effect. ConclusionShaoyaotang can relieve diarrhea and bloody stool in mice with ulcerative colitis by restoring the Th17/Treg cell balance via regulation of glucose metabolism reprogramming, thus playing a role in the treatment of ulcerative colitis.
