Mechanism of "Pinelliae rhizoma-Arisaematis rhizoma" in treatment of lung cancer based on network pharmacology

Objective:The study was designed to explore the mechanism of“Pinelliae RhizomaArisaematis Rhizoma”(PR-AP)in treatment of lung cancer based on network pharmacology.Methods:The active components and their targets of“Pinelliae Rhizoma-Arisaematis Rhizoma”were screened out from TCMSP database.The cytoscape3.7.0 software was used to construct the drug-active component-targets network.Searched the DisGeNet database to obtain lung cancer related targets.Bisogenet was used to construct"PPI network of active component target"and"PPI network of lung cancer target",and the intersection of the two networks was taken and the target was screened.AutoDockTools software was used to dock the key active ingredients with the key targets.David database was used to perform Go biological process enrichment analysis and KEGG pathway enrichment analysis.Results:A total of 15 active components were collected,including beta-sitosterol,baicalein,Stigmasterol,Cavidine,coniferin,etc.These active components mainly act on 95 key targets such as ESR1 and CDK2,which enriched in multiple lung cancer related signaling pathways,such as PI3KAkt、MAPK、HIF-1、FoxO、TGF-β、Hippo、TNF、Notch、VEGF、cAMP,etc.The results of molecular docking showed that the active components could regulate the core targets(ESR1 and CDK2).Conclusion:The effect of“Pinelliae Rhizoma-Arisaematis Rhizoma”in the treatment of lung cancer embodies the characteristics of multi-component,multi-target and multi-pathway of traditional Chinese medicine.Its mechanism of action may be to play a role in the treatment of lung cancer by regulating cell cycle,angiogenesis,tumor stem cells,etc.This research can provide ideas and references for further research.

Effect of electroacupuncture combined with ginger-isolated moxibustion on endometrial receptivity in infertile patients with polycystic ovarian syndrome

Objective:To observe the effect of the combined therapy of electroacupuncture(EA) and ginger-isolated moxibustion on endometrial receptivity in the patients with polycystic ovarian syndrome(PCOS).Methods:A total of 70 subjects of PCOS were randomized into two groups,35 cases in each one.In the western medication group,letrozole and human chorionic gonadotropin(HCG) were administered.In the combined therapy group,on the base of the treatment as the western medication group,the artificial cycle therapy with EA and ginger-isolated moxibustion was provided.The treatment duration was 3 menstrual cycles in two groups.After treated for 3 menstrual cycles,the symptom score of traditional Chinese medicine(TCM),endometrial thickness,the number of ovulation cycle,endometrial morphology,bilateral uterine artery pulsatility index(PI),resistance index(RI),the sum of peak systolic velocity/end diastolic velocity(S/D) and pregnancy were compared in the patients between two groups.Results:(1) After treatment,the endometrial thickness was better(0.21 ± 0.13 vs 0.14 ± 0.08,P <0.01),TCM symptom score reducing range was larger(5.00 ± 2.24 vs 0.52 ± 1.66,P <0.01),the reducing degrees of bilateral uterine artery PI,RI and S/D sum were better(0.62 ± 0.26 vs 0.04 ± 0.15,0.08± 0.05 vs0.01±0.05,0.61±0.33 vs 0.07±0.17,0.11±0.05 vs 0.01 ± 0.05,4.80±1.14 vs 0.15 ± 0.89,all P <0.01) in the combined therapy group respectively as compared with the western medication group.After treatment,the number of ovulation cycle and the proportion of A+B type of endometrial morphological were higher in the combined therapy group(2.09 ± 0.78 vs 1.27 ± 0.84,87.5% vs 60.61%,P <0.01,P <0.05) as compared with the western medication group respectively.(2) The clinical pregnancy rate was56.25% in the combined therapy group,better than 30.30% in the western medication group(P <0.05).The early abortion rate was 10.53% in the combined therapy group,lower than 50.00% in the western medication group(P <0.05).Conclusion:The combined treatment of electroacupuncture and ginger-isolated moxibustion with western medication effectively improves endometrial receptivity,increases clinical pregnancy rate and reduces early abortion rate in the patients with PCOS.
