Colorectal cancer(CRC) is a common malignant tumor worldwide. Due to the treatment intolerance and side effects, CRC rank the top among various cancers regarding the incidence and mortality rates. Therefore, exploring new therapies is of great significance for the treatment of CRC. Aerobic glycolysis(AEG) plays an important role in the microenvironment formation, proliferation, metastasis, and recurrence of CRC and other tumor cells. It has been confirmed that intervening in the AEG pathway can effectively curb CRC. The active ingredients and compound prescriptions of traditional Chinese medicine(TCM) can effectively inhibit the proliferation, metastasis, and drug resistance and regulate the apoptosis of tumor cells by modulating AEG-associated transport proteins [eg, glucose transporters(GLUT)], key enzymes [hexokinase(HK) and phosphofructokinase(PFK)], key genes [hypoxia-inducible factor 1(HIF-1) and oncogene(c-Myc)], and signaling pathways(MET/PI3K/Akt/mTOR). Accordingly, they can treat CRC, reduce the recurrence, and improve the prognosis of CRC. Although AEG plays a key role in the development and progression of CRC, the specific mechanisms are not yet fully understood. Therefore, this article delves into the intrinsic connection of the targets and mechanisms of the AEG pathway with CRC from the perspective of tumor cell glycolysis and explores how active ingredients(oxymatrine, kaempferol, and dioscin) and compound prescriptions(Quxie Capsules, Jiedu Sangen Decoction, and Xianlian Jiedu Prescription) of TCM treat CRC by intervening in the AEG pathway. Additionally, this article explores the shortcomings in the current research, aiming to provide reliable targets and a theoretical basis for treating CRC with TCM.

Prostate cancer(PCa) is a common malignant tumor among elderly men, with high incidence and mortality rates worldwide, posing a serious threat to human health. Traditional treatments face limitations, highlighting the urgent need for novel therapeutic strategies. Recent studies on the regulatory mechanisms of micro ribonucleic acid(microRNA, miRNA) in tumor development has identified miRNA as new targets for PCa diagnosis and treatment. Traditional Chinese medicine(TCM), with its multi-mechanism, multi-target, and multi-pathway regulatory properties, shows promising potential in miRNA-based PCa therapy. This review summarized recent findings on miRNA' roles in PCa and research progress of TCM intervention and found that a variety of miRNA played important regulatory roles in cell differentiation, proliferation, apoptosis, invasion, metastasis, immune microenvironment, and drug resistance, and their potential as biomarkers for PCa diagnosis, prognosis, and therapy, indicating the potential to be a biomarker for the diagnosis, prognosis evaluation, and treatment of PCa. The review concluded that the active components of TCM(terpenoids, flavonoids, alkaloids, and others) and compounds(Yishen Tonglong Decoction, Shenhu Decoction, Zhoushi Qiling Decoction, Fuzheng Yiliu Decoction, and Qilan Formula) could regulate the expression of their downstream target genes by acting on specific miRNA and affect the above biological behaviors of PCa cells, thus playing a role in the treatment of PCa. This review aims to provide a theoretical basis for miRNA as potential biomarkers and therapeutic targets for PCa and suggest new avenues for further development of targeted therapy strategies against miRNA.

Benign prostatic hyperplasia(BPH) is a common disease in middle-aged and elderly men, with lower urinary tract symptoms as the main manifestation, severely affecting the quality of life of patients. The pathogenesis of BPH is not yet fully understood, and there are still some challenges and limitations in western medicine treatment for BPH. Therefore, finding new and more effective treatment strategies is urgent. In recent years, many basic and clinical studies have confirmed the important role of traditional Chinese medicine in the treatment of BPH. This article reviews the progress of basic and clinical research in the treatment of BPH with traditional Chinese medicine, and believes that basic research mainly focuses on the active ingredients of Chinese medicine [regulating pathways such as NF-E2-related factor 2(Nrf2)/antioxidant response element(ARE), nuclear factor κB(NF-κB), epidermal growth factor receptor(EGFR)/signal transducer and activator of transcription 3(STAT3), phosphoinositide 3-kinase(PI3K)/protein kinase B(Akt)/mammalian target of rapamycin(mTOR), p38 mitogen-activated protein kinase(p38 MAPK)/forkhead box O subtype(FOXO3a), etc.], single Chinese herbs(regulating inflammatory factors, oxidative stress-related proteins, cell cycle-related proteins, and apoptotic factors, etc.), and Chinese herbal compounds and patent medicines [regulating extracellular signal-regulated kinase(ERK1/2), transforming growth factor-β(TGF-β)/Smad, mitogen-activated protein kinase(MAPK), PI3K/Akt, Nrf2, trefoil factor 2(TFF2)/Wnt, interleukin-6(IL-6)/Janus kinase 2(JAK2)/STAT3, hypoxia-inducible factor 1α(HIF-1α)/vascular endothelial growth factor receptor(VEGFR), etc.], and then play a therapeutic role by inhibiting BPH cell proliferation, oxidative stress, inflammatory response, promoting apoptosis, and inhibiting epithelial-mesenchymal transition. Clinical studies mainly focus on internal treatment, external treatment, combined internal and external treatment, and integrated Chinese and western medicine treatment as the main methods, aiming to improve traditional Chinese medicine syndrome scores, prostate symptom scores, residual urine volume, effective bladder volume, sexual quality of life, increase average urine flow rate, maximum urine flow rate, and promote balance of sex hormone secretion. Through this research, it is hoped to provide some reference ideas for clinical research and drug development for BPH.

Objective: Explore the association between atrial fibrillation (AF) reoccurrence and new-onset ischemic stroke (IS) in patients with nonvalvular AF, and explore whether there is a high-risk period of IS after recurrent episodes of AF. Methods: A nested case-control study design was used. A total of 565 nonvalvular AF patients with new-onset IS after a follow-up of at least 2 years in the China-AF cohort were enrolled as the case group, and 1 693 nonvalvular AF patients without new-onset IS were matched as the control group at a ratio of 1∶3. Frequency and types of recurrent AF in the previous 1 or 2 years were compared between two groups, and the adjusted associations of AF reoccurrence with new onset IS were explored using conditional logistic regression analysis. The proportion of recurrent AF was compared between the case period and control period, and conditional logistic regression analysis was performed to calculate adjusted associations of case-period AF with IS. Results: The nested case-control study design results showed that the proportion of at least one record of recurrent AF in the previous 1 year was higher in the case group than in the control group (72.0% vs. 60.8%, P<0.05), and the recurrent AF was positively correlated with new-onset IS (adjusted OR=1.80, P<0.001). Similar results were also observed in the previous 2 years period. The case-crossover study design analysis showed that among 565 patients with new-onset IS, recurrent AF in the case period was positively correlated with IS (adjusted OR=1.61, P=0.003). Conclusion: Recurrent AF is associated with IS, and there may be a high-risk period of IS after recurrent episodes of AF.

Aim To identify the molecular target of gabapentin in the treatment of postherpetic neuralgia(PHN). Methods The molecular target of gabapentin for PHN was analyzed by network pharmacology and molecular docking and confirmed by coprecipitation test. Rats were randomly divided into control group, model group, model+50 mg·kg-1 gabapentin group, model+100 mg·kg-1 gabapentin group, and model+200 mg·kg-1 gabapentin group, with nine rats in each group. The pain-related behaviors of the rats were measured at different time points. The mRNA and protein expressions of CACNA2D1, Bax, and Bcl-2 in rat spinal cord were determined by immunofluorescence, Western blot, and qPCR. Results CACNA2D1 was the target gene of gabapentin that determined via network pharmacology, molecular docking, and co-precipitation tests. After modeling, mechanical pain threshold and thermal pain threshold significantly decreased, and the number of apoptotic GABA cells significantly increased. However, after intraperitoneal injection of 50, 100, and 200 mg·kg-1 gabapentin, mechanical pain threshold and thermal pain threshold significantly increased(P<0.05), and the number of apoptotic GABA cells significantly decreased(P<0.01). Immunofluorescence and Western blot results showed that compared with the model group, with the increase of gabapentin concentration, the positive expression rate of Bax significantly decreased, and the positive expression rate of Bcl-2 and CACNA2D1 significantly increased. The mRNA expression levels of Bax, Bcl-2 and CACNA2D1 detected by qPCR were consistent with the results of immunofluorescence and Western blot. Conclusions Gabapentin up-regulates the expression of target protein CACNA2D1, inhibits the proapoptotic protein Bax, and promotes the expression of apoptotic inhibitor Bcl-2.

OBJECTIVES: To explore the cytotoxicity of four wild mushrooms involved in a case of Yunnan sudden unexplained death (YNSUD), to provide the experimental basis for prevention and treatment of YNSUD. METHODS: Four kinds of wild mushrooms that were eaten by family members in this YNSUD incident were collected and identified by expert identification and gene sequencing. Raw extracts from four wild mushrooms were extracted by ultrasonic extraction to intervene HEK293 cells, and the mushrooms with obvious cytotoxicity were screened by Cell Counting Kit-8 (CCK-8). The selected wild mushrooms were prepared into three kinds of extracts, which were raw, boiled, and boiled followed by enzymolysis. HEK293 cells were intervened with these three extracts at different concentrations. The cytotoxicity was detected by CCK-8 combined with lactate dehydrogenase (LDH) Assay Kit, and the morphological changes of HEK293 cells were observed under an inverted phase contrast microscope. RESULTS: Species identification indicated that the four wild mushrooms were Butyriboletus roseoflavus, Boletus edulis, Russula virescens and Amanita manginiana. Cytotoxicity was found only in Amanita manginiana. The raw extracts showed cytotoxicity at the mass concentration of 0.1 mg/mL, while the boiled extracts and the boiled followed by enzymolysis extracts showed obvious cytotoxicity at the mass concentration of 0.4 mg/mL and 0.7 mg/mL, respectively. In addition to the obvious decrease in the number of HEK293 cells, the number of synapses increased and the refraction of HEK293 cells was poor after the intervention of Amanita manginiana extracts. CONCLUSIONS The extracts of Amanita manginiana involved in this YNSUD case has obvious cytotoxicity, and some of its toxicity can be reduced by boiled and enzymolysis, but cannot be completely detoxicated. Therefore, the consumption of Amanita manginiana is potentially dangerous, and it may be one of the causes of the YNSUD.
