Objective:To explore the potential targets and mechanism of action of "Clematis Radix et Rhizoma-Trichosanthis Radix" based on network pharmacology. Method:Chinese Medicine System Pharmacology Analysis Platform(TCMSP) was used to screen out active ingredients and corresponding target proteins of Clematis Radix et Rhizoma and Trichosanthis Radix according to oral bioavailability(OB) and drug likeness(DL),cancer disease targets were screened out using GeneCards and OMIM databases,R language software was used to screen out common targets of clematis,trichosanthin and cancer diseases, Cytoscape 3.7.2 software was used to construct a network map of "drug-active ingredient-disease-target", STRING database was used to draw protein protein interaction(PPI)of common target proteins, R language software was used to perform enrichment analysis of gene ontology(GO) functions and Kyoto encyclopedia of genes and genomes(KEGG) channels on effective targets. Result:A total of 9 effective active ingredients were obtained from Clematis Radix et Rhizoma-Trichosanthis Radix powder pair. A total of 31 target genes were searched,and 814 relevant target genes were searched from cancer diseases. The two kinds of relevant target genes were matched to obtain 9 common target genes,which mainly involved endopeptidase,cysteine-type endopeptidase activities involving in the apoptosis process and cancer necrosis factor receptor superfamily binding and other biological processes,and played a role in the treatment of cancers by regulating apoptosis,measles,hepatitis B,kaposi sarcoma-associated herpesvirus infection,p53,interleukin-17(IL-17),tumor necrosis factor(TNF) and many other pathways. Conclusion:The mechanism of Clematis Radix et Rhizoma-Trichosanthis Radix in the treatment of cancer is preliminarily studied. Clematis Radix et Rhizoma-Trichosanthis Radix has multiple active ingredients and can play a role in treating cancer through multiple targets and multiple pathways.

Objective:The Meta-analysis was used to systematically evaluate the clinical efficacy of traditional Chinese medicine in treating Late onset hyponatremia (late onset hyponatremia,LOH). Method:Pubmed,Web of Science,China Knowledge Base Database (CNKI),Wanfang Database (WanFang),Weipu Full-text Periodical Database(VIP),Chinese Biomedical Literature Database (CBM)were retrieved to collect randomized controlled trials of traditional Chinese medicine(TCM) for treatment of LOH. Two researchers independently screened out the literatures, extracted the data, conducted quality assessment by Cochrance bias risk assessment tool,and made Meta-analysis by RevMan 5.3.5 software. Result:Nine eligible documents were finally included. Meta-analysis results showed that the test group was superior to the control group in improving patient's physical fitness/cardiovascular score [mean deviation(MD)=-1.42,95% CI(-2.39,-0.45),<italic>P</italic>=0.004] and psycho-psychological score[MD=-0.74,95% CI(-1.26,-0.22),<italic>P</italic>=0.005],with no statistically significant difference between test group and control group in sexual function score [MD=-0.68,95% CI(-1.38,-0.03),<italic>P</italic>=0.06],serum testosterone (TT) concentration[MD=-0.68,95% CI(-1.38,-0.03),<italic>P</italic>=0.06] and effective rate [odds ratio(OR)=1.57,95% CI(0.64,3.88),<italic>P</italic>=0.33]. Conclusion:TCM is equivalent to western medicine(testosterone undecanoate)in the treatment of late onset hypogonadism, and better than western medicine in improving patients' physical fitness/cardiovascular score and mental and psychological score.

Six compounds were isolated from the aerial part of cultivated Clerodendranthus spicatus in Hainan with various chromatographic techniques,and their structures were determined as:1-dehydroxy-1-oxo-rupestrinol(1),N-trans-feruloyltyramine(2),methyl 3,4-dihydroxyphenyllactate(3),caffein acid(4),methyl caffeate(5) and ethyl caffeate(6),via analysis of physicochemical properties and spectroscopic evidence.Compound 1 was a new compound,while compounds 2 and 3 were isolated from C.spicatus for the first time.Biological activity results showed that compounds 2-4 exhibited α-glucosidase inhibitory activity with different inhibition ratio.
