RESUMO
OBJECTIVE To explore the effects of posaconazole combined with proton pump inhibitors （PPI） on the blood concentration and the risk of invasive fungal disease （IFD） in patients with malignant hematological disorder. METHODS In accordance with the random number table method， 40 patients with malignant hematological disorders who were admitted to the hematology department of our hospital between December 2020 and December 2021 were chosen and divided into control group （20 cases） and observation group （20 cases）. The control group received Posaconazole oral suspension alone， while the observation group received Posaconazole oral suspension combined with PPI. The incidence of IFD， attainment rate of blood concentration， the time from the start of prophylaxis to IFD onset， the fatality associated with IFD， treatment of infected patients， and blood concentrations of posaconazole on 7th， 14th， 21st， and 28th day after posaconazole application were compared between 2 groups； the occurrence of adverse events during drug administration in the two groups was recorded. RESULTS The study was stopped because 2 patients in the observation group and 9 patients in the control group received hospital departures after taking posaconazole for fewer than 7 days. The incidence of IFD in the observation group was significantly higher than control group， and the attainment rate of blood concentration in the observation group was significantly lower than control group （P＜0.05）. There was no significant difference in the time from the start of prophylaxis to IFD onset， the fatality associated with IFD， treatment of infected patients and the incidence of adverse events （P＞ 0.05）. The blood concentration of posaconazole in the observation group was significantly lower than control group on 7th day of medication （P＜0.05）； there was no significant in blood concentration of posaconazole between 2 groups on the 14th day of medication （P＞0.05）. CONCLUSIONS Posaconazole combined with PPI can reduce the blood concentration of patients with malignant hematological disorders， increase the risk of IFD. Clinical practice should try to avoid the combination of the two or use them under the guidance of therapeutic drug monitoring.
RESUMO
Objective To explore the molecular targets and associated potential pathways of Kunxian capsule in the treatment of rheumatoid arthritis (RA) based on network pharmacology. Methods The constituents of Kunxian capsule were searched by Traditional Chinese Medicine Systems Pharmacology Database, Analysis Platform (TCMSP) and a high-throughput experiment- and reference-guided database of traditional Chinese medicine（HERB）.The potential active ingredients and targets were retrieved based on TCMSP database. RA related gene targets were retrieved through GeneCards database and OMIM database. Venn online software was used to obtain the common target of drugs and diseases. The “compound-target” network diagram was constructed with Cytoscape software. String database was used to draw the protein interaction (PPI) network. Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis of the intersection network were conducted by Bioconductor Database. Results 81 active ingredients and 913 targets were identified. 228 targets were obtained after removing the duplicates. 4494 target genes directly related to RA were obtained from the GeneCards databases and OMIM databases. 162 genes were obtained from the intersection of component-target and disease-target. It was revealed that five ingredients including quercetin, luteolin, kaempferol, β-sitosterol and triptolide are the main active ingredients in Kunxian capsule. AKT1, IL-10, STAT3, CASP8 and CDKN1A may be the main therapeutical targets. The results of GO and KEGG enrichment analysis showed that the mechanism of Kunxian capsule is mainly related to the regulation of reactive oxygen metabolism, the regulation of kinase activity, and IL-17 signaling pathway. The important biological processes and signaling pathways include infection, inflammation and immunity. Conclusion This research preliminarily explored the mechanism of Kunxian capsule in the treatment of RA by network pharmacology and suggested that the overall regulation is characterized by multi-components, multi-targets, and multi-channels. It provided some ideas for further molecular biology experiments.
RESUMO
Objective:To reveal the characteristics of pulse condition of kidney qi deficiency and kidney yin deficiency syndrome,investigate the correlation between syndrome and pulse condition,and provide objective evidence for syndrome differentiation and traditional Chinese diagnosis.Methods:40 cases of kidney qi deficiency,35 cases of kidney yin deficiency and 25 people of control group were involved into the study.We used DY-SS-1 detective system of pulse condition,which had three probes and was designed according to traditional Chinese medical theories,to examine,record and analyze the messages of Cun,Guan and Chi of two hands.Results:Comparative analysis of pulse condition and syndrome differentiation showed a conclusion that the accurate diagnosis of sufferers was 68% while of controls was 88%,there was signif icant difference between them(P
