摘要:Molecular targeted therapy is one of the main treatment options for metastatic colorectal cancer (mCRC), and combined with chemotherapy, it can provide significant benefits in patients' overall survival (OS) and progression-free survival (PFS). Commonly used molecular targeted drugs in clinic mainly includes small molecule signal transduction inhibitors and large molecule monoclonal antibodies. However, the problem of drug resistance in the later stage of targeted therapy becomes a key challenge for clinic treatment. Studies have shown that the mechanism of targeted drug resistance may be related to a variety of factors, including abnormalities in related cell signaling pathways such as epidermal growth factor receptor (EGFR), vascular endothelial growth factor (VEGF), human epidermal growth factor receptor 2 (HER2) and alterations in tumor microenvironment. In recent years, studies have found that traditional Chinese medicine are quite effective in reversing targeted drug resistance. Therefore, this article discusses the mechanisms of drug resistance to molecular targeted therapy in CRC, as well as the coping strategies of traditional Chinese medicine, and discusses the tradional Chinese medicine and its active ingredients that can reverse targeted drug resistance.

摘要:Objective: To investigate the effect of pulse-taking acupuncture combined with chin tuck against resistance (CTAR) training on swallowing function in nasopharyngeal carcinoma (NPC) patients with swallowing disorder (SD) after radiotherapy.MethodsA randomized controlled method was applied. Sixty NPC patients with SD after radiotherapy were randomly divided into the CTAR training group and combination group, 30 cases in each group. All the patients were treated with routine training. Based on above, the patients in the CTAR training group were treated with CTAR training, and the patients in the combination group were treated with pulse-taking acupuncture combined with CTAR training. The intervention period of both groups was 4 weeks. Before and after intervention, the water swallowing test (WST) grading and the videofluoroscopic swallowing study (VFSS) score of the two groups were evaluated and compared; the levels of albumin (ALB) and prealbumin (PA) of the two groups were detected and compared in order to evaluate the nutritional status of the patients; the incidence of aspiration was compared between the two groups; the swallowing-quality of life (SWAL-QOL) was used to evaluate the life quality of the patients in the two groups.Results①After intervention, the WST grading in both groups were better than that before intervention (P<0.05), and the WST grading in the combination group was superior to the CTAR training group (P<0.05). ②After intervention, the VFSS scores in both groups were significantly increased compared with those before intervention (P<0.05), and the score of the combination group was higher than that of the CTAR training group (P<0.05). ③After intervention, the levels of ALB and PA in both groups were significantly increased compared with those before intervention (P<0.05), and the levels of ALB and PA in the combination group were higher than those in the CTAR training group (P<0.05). ④In the 4 weeks of intervention, the incidence of aspiration was 3.33% in the combination group and 26.67% in the CTAR training group, and the incidence of aspiration in the combination group was obviously lower than that in the CTAR training group (P<0.05). ⑤After intervention, the SWAL-QOL scores in both groups were significantly increased compared with those before intervention (P<0.05), and the score of the combination group was higher than that of the CTAR training group (P<0.05).ConclusionPulse-taking acupuncture combined with CTAR training can significantly improve the swallowing function and nutritional status in NPC patients with SD after radiotherapy, effectively reduce the incidence of aspiration, and enhance the life quality of the patients.

摘要:Chronic pain is one of the most difficult diseases to cure in the world. In the past, it was thought that the appearance of chronic pain was only related to the plasticity of neurons, but now more and more attention has been paid to the important involvement of non-neuronal cells, especially microglia. Electroacupuncture has gradually become an alternative therapy for chronic pain due to its safety and effectiveness, and its analgesic effect can be achieved by inhibiting the overactivation of microglia. Based on the regulation effect of electroacupuncture on the microglia activation in chronic pain, the analgesic mechanism of electroacupuncture is discussed, in order to provide a basis for the effectiveness of clinical electroacupuncture analgesia.
摘要:Functional constipation is a common disease in the elderly. Studies have shown that acupuncture and moxibustion have good effects on increasing the patients' defecation frequency, improving defecation difficulty, reducing the recurrence rate of the disease, and improving the quality of life of the patients. Its mechanism of action is related to regulating the enteric nervous system and related neurotransmitters, improving anorectal dynamics-related indicators, and the regulation of the central nervous-gut-microbiome (brain-gut axis). This article reviews the clinical and mechanism researches on the treatment of functional constipation in the elderly with simple acupuncture, the combination of acupuncture and medicine, acupoint catgut embedding, and auricular point pressure pills, etc., so as to provide more ideas and directions for the research on the mechanism of acupuncture and moxibustion in treatment of functional constipation in the elderly.

摘要:Objective: To explore the anti-inflammatory effect of the components absorbed into serum of the aqueous extract of "Curculiginis Rhizoma and Epimedii Folium" (EX).MethodsAutoDockTools software was used to dock the five components absorbed into serum of EX (Curculigoside, Icariin, Baohuoside I, Oricinol glucoside and Epimedin A) with target protein TREM2. CCK8 method was used to detect the effects of the five components on BV2 cell viability at different concentrations. LPS was used to stimulate BV2 or mouse bone marrow-derived BMDMs cells and Nigericin to stimulate LPS pretreated BMDMs cells to establish inflammatory models, and the effects of the five components on TNF-α and IL-1β levels in the cell supernatant were detected by ELISA.ResultsThe components absorbed into serum of EX including Curculigoside, Icariin, Baohuoside I and Epimedin A, bound very stably to TREM2, while the binding of Orcinol glucoside to TREM2 was relatively stable. Curculigoside, Icariin, Baohuoside I, Orcinol glucoside and Epimedin A all reduced the level of IL-1β produced by BMDMs at certain concentrations, while only high concentrations of Curculigoside and Icariin reduced the level of TNF-α produced by BMDMs.Conclusion5 components absorbed into serum of EX could all bind to TREM2 and inhibit downstream NF-κB or NLRP3 inflammatory pathways to improve inflammation, which might be an effective material basis for EX to regulate TREM2 to improve learning and memory ability and neuroinflammation, and work synergistically in EX.

摘要:Objective: To predict the active components of Salviae Miltiorrhizae Radix Et Rhizoma in the treatment of chronic pain using quantitative structure-activity relationship (QSAR) machine learning model and molecular docking technology, and to explore the molecular mechanism of Salviae Miltiorrhizae Radix Et Rhizoma in the treatment of chronic pain combined with the theory of "prolonged illness leading to stasis" and network pharmacology.MethodsFirst, the chemical components of Salviae Miltiorrhizae Radix Et Rhizoma and targets of chronic pain were collected through the Traditional Chinese Medicine System Pharmacology Database and Analysis Platform (TCMSP) and the Human Genome database (GeneCards), and the core targets were screened. And the protein interaction (PPI) network was analyzed by STRING database. Then, the intersection targets were analyzed by Gene Ontology (GO) enrichment analysis and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis. Finally, the QSAR machine learning model and molecular docking technology were used to screen the active ingredients and core targets of Salviae Miltiorrhizae Radix Et Rhizoma in the treatment of chronic pain.Results①Fifty-five intersection targets and 55 potential active components of Salviae Miltiorrhizae Radix Et Rhizoma in the treatment of chronic pain were screened. The core targets such as serine/threonine kinase 1(AKT1), epidermal growth factor receptor (EGFR) and interleukin (IL)-6 were found through PPI analysis. ②Through the function enrichment analysis, 45 cell components, 87 molecular functions, 1 450 biological processes and 140 signaling pathways were obtained, involving signaling pathways such as phosphatidylinositol-3-kinase/protein kinase B(PI3K/AKT), IL-17, hypoxia-inducible factor 1(HIF-1), cyclic adenosine monophosphate (cAMP), and mitogen-activated protein kinases (MAPK) signaling pathway. ③Through QSAR model and molecular docking, it was found that salvilenone, epidanshenspiroketallactone, salvianan A, isotanshinone Ⅱ and salvianolic acid C in Salviae Miltiorrhizae Radix Et Rhizoma were the active components for treating chronic pain.ConclusionThe active components of Salviae Miltiorrhizae Radix Et Rhizoma in treating chronic pain are diterpenoids, and its mechanism of action is probably related to the regulation of AKT1-mediated signaling pathways.
摘要:Objective: To investigate the anticancer activity of dihydroartemisinin(DHA)on RKO cells in vivo and its mechanism in vitro.Methods40 RKO tumor-bearing mouse models were established in specific pathogen-free male nude mice and randomly divided into model group,cisplatin group,high dose DHA(200 mg/kg)group,and low dose DHA(100 mg/kg)group,with 10 mice in each group. The body weight,tumor volume,tumor mass,tumor inhibition rate and serum,tumor necrosis factor-α(TNF-α)level of each group were compared. Hematoxylin-eosin (H&E) staining was used to observe tumor histopathological changes in nude mice of each group. MTT assay was used to detect the effects of DHA at different concentrations(25,50,100 μmol/L)on the proliferation of RKO cells within 0,24,48,and 72 h. Flow cytometry and Hoechst 33258 were used to detect the effects of DHA (0,50,95,150 μmol/L)on the cell cycle and apoptosis of RKO cells after 48 h intervention. Wound healing assay was used to observe the effect of 95 μmol/L DHA on cell migration. Real Time Quantitative PCR (RT-qPCR) was used to detect the effect of DHA on the mRNA expression levels of Caspase-3, Caspase-9, Bcl-2 and Bax. Western blot was used to detect the effect of DHA on the expression levels of Caspase-3, Caspase-9, Bcl-2, Bax, p38-MAPK, p-p38-MAPK, PI3K, p-PI3K, Akt, p-Akt and MMP-9.ResultsTumor volume and mass were significantly reduced and the serum level of TNF-α was lowered by 200 mg/kg DHA, and the tumor inhibition rate was 41.45%. The inhibitory effect on RKO cell proliferation was enhanced with increasing concentration of DHA. RKO cell cycle was arrested in the G2/M phase by (50,95,150 μmol/L)DHA,and the effect of promoting RKO cell apoptosis was enhanced with the increase of DHA concentration. The migration ability of RKO cells was significantly reduced after intervention with 95 μmol/L DHA for 12 and 24 h (P<0.01). The mRNA expression levels of Caspase-3 and Caspase-9 in RKO cells were significantly up-regulated by 95 μmol/L DHA(P<0.01), and Bax/Bcl-2 mRNA expression ratio was also significantly up-regulated(P<0.05). The protein expressions of cleaved-Caspase-9/Caspase-9 and Bax/Bcl-2 in RKO cells were increased by 95 μmol/L DHA(P<0.01), while the protein expression levels of MMP-9, p-P38 MAPK, p-PI3K, p-Akt and Akt were decreased(P<0.01).ConclusionDHA has a good inhibitory effect on colorectal cancer,and its mechanism may be to trigger the endogenous apoptosis of RKO cells to prevent their proliferation and migration through inhibiting the MAPK/PI3K/Akt signaling pathway.
摘要:Sepsis is a systemic inflammatory response caused by the dysregulations of host immune response to infection, leading to life-threatening organ dysfunction. The nucleotide binding oligomerization domain (Nod)-like receptor protein 3 (NLRP3) inflammasome plays an important role in the innate immune system. Studies have shown that activation of the NLRP3 inflammasome can lead to further aggravation of systemic inflammation during the process of multiple organ damage in sepsis. Therefore, it is crucial to elucidate the activation mechanism of NLRP3 inflammasome and its pathogenic role in multiple organ damage in sepsis. This article will review the latest progress of the above research, and elaborate the therapeutic effect of traditional Chinese medicine on sepsis from the perspective of NLRP3 inflammasome, so as to provide some references for the treatment of multiple organ damage in sepsis.
