文摘As an important representative of the modernization of the Chinese medicine industry,traditional Chinese medicine(TCM)compound preparations are an indispensable part of the development of TCM.The complex ingredients and unclear action mechanism of TCM compound preparations restrict the development of TCM.In line with this problem,the modern TCM research has made extensive remarkable achievements.From the single indicator in the past to multiple indicator,the research on the combination of TCM fingerprints and pharmacodynamics also has made great progress.The introduction of quality evaluation methods such as the"quantitative analysis of multi-components by a single marker","dose-effect"indicator,"Bioactive Equivalent Combinatorial Components"(BECCs)and TCM quality markers have brought new ideas for quality control of TCM compound preparations.

文摘Background:Sjögren syndrome(SS)is a long-term autoimmune disease that affects the body’s moisture-producing glands.It can occur independently of other health problems(primary disease)or as a result of another connective tissue disorder(secondary disease).Medication is directed at the person’s symptoms.Recently,it is reported that prescription of Chinese medicine has a great effect on SS and reduce adverse drugs reaction,which can provide a more safer treatment to SS.Case presentation:We here report a 43 year-old Chinese patient with continuous immune thrombocytopenia diagnosed as Sjögren syndrome,who was not response to routine medication such as Methylprednisolone and acyclovir.After that,the patient was treated by prescription of Chinese medicine,and the symptoms were improved apparently.We suppose that prescription of Chinese medicine has an unexpected effect on SS,which can alleviate patient’s symptoms.Conclusion:The clinical efficacy of Sjogren syndrome(SS)is effective in the treatment of prescription of Chinese medicine.It can improve patient’s symptoms and reduce adverse drug reactions.
文摘Background:Long non-coding RNA(lncRNA)actin filament-associated protein 1 antisense RNA 1(AFAP1-AS1)functions as a competing endogenous RNA to regulate target genes expression by sponging microRNAs(miRs)to play cancer-promoting roles in cancer stem cells.However,the regulatory mechanism of AFAP1-AS1 in cervical cancer(CC)stem cells is unknown.The present study aimed to provide a new therapeutic target for the clinical treatment of CC.Methods:Hyaluronic acid receptor cluster of differentiation 44 variant exon 6(CD44v6)(+)CC cells were isolated by flow cytometry(FCM).Small interfering RNAs of AFAP1-AS1(siAFAP1-AS1)were transfected into the(CD44v6)(+)cells.The levels of AFAP1-AS1 were measured by quantitative real-time PCR(qRT-PCR).Sphere formation assay,cell cycle analysis,and Western blotting were used to detect the effect of siAFAP1-AS1.RNA pull-down and luciferase reporter assay were used to verify the relationship between miR-27b-3p and AFAP1-AS1 or vascular endothelial growth factor(VEGF)-C.Results:CD44v6(+)CCcells had remarkable stemness and a high level ofAFAP1-AS1.However,AFAP1-AS1knockdownwithsiAFAP1-AS1suppressed the cell cycle transitionofG(1)/S phase and inhibited self-renewal ofCD44v6(+)CCcells,the levels of the stemnessmarkers octamer-binding transcription factor 4(OCT4),osteopontin(OPN),and cluster of differentiation 133(CD133),and the epithelialmesenchymal transition(EMT)-related proteins Twist1,matrix metalloprotease(MMP)-9,and VEGF-C.In the mechanism study,miR-27b-3p/VEGF-C signaling was demonstrated to be a key downstream of AFAP1-AS1 in the CD44v6(+)CC cells.Conclusions:LncRNA AFAP1-AS1 knockdown inhibits the CC cell stemness by upregulating miR-27b-3p to suppress VEGF-C.
