OBJECTIVE:To explore the regularity of relative correction factor (RCF) in multi-components by single marker (QAMS). METHODS:With the source of CNKI,literature retrieval was used to collect the relevant documents of multi-compo-nents by single marker (QAMS) and extract the calculated values by quantitative analysis of multi-components by single marker QAMS and measured values by external standard method (ESM),SPSS 19.0 software was used to calculate the percentage value (RSD,%) of relative standard deviation between calculated values and measured values,and the correlation between RSD and RCF was analyzed by drawing a scatter plot. RESULTS:Most of RCF values distributed in the range of >0.62-1.53,accounting for 76.7%to all data. Calculated values and measured values showed high similarity in this range and the RSD<3.0%data account-ed for 88.8% to all data,which had good credibility. Meanwhile,the similarity of calculated values and measured values was influ-enced by the differences of structure and physicochemical property of parent nucleus between other components under measured and internal references. The high degree of similarity between calculated values and measured values were decisive by very similar struc-tures of parent nucleus;the low degree was decisive by discrepant structures;and the low degree was also decisive by very similar structures and discrepant physicochemical property of parent nucleus. CONCLUSIONS:RCF will affect the credibility of content de-termination results for components under measured in QAMS,it is necessary to establish database of RCF,RSD and related param-eters.

Pulmonary administration can directly deliver drugs to the lungs， making it the preferred mode of administration for pulmonary disease. Active ingredients of traditional Chinese medicine （TCM）， such as quercetin and paclitaxel have demonstrated promising therapeutic effects on lung diseases. However， they face challenges such as poor water solubility and high lung clearance rates. Loading the active ingredients of TCM onto nano-drug delivery systems can enhance their water solubility， stability， permeability and retention in the lungs. Based on this， this study reviewed the research progress on inhalation nano-drug delivery systems for the active ingredients of TCM in the treatment of lung diseases. It was found that there are nano-drug delivery systems for TCM active ingredients based on chitosan， lipids （including liposomes， solid lipid nanoparticles， and nanostructured lipid carriers）， and targeting ligands （including targeting folate receptor， targeting transferrin receptor， and exosomes）. These inhalation nano-drug delivery systems comprehensively consider key factors such as particle size， surface charge， and hydrophobicity， which can prevent the drugs from being cleared by mucus， cilium and macrophages， thus exhibiting great potential for application.

Gambogic acid is the main active component of Garcinia hanburyi Hook. f. ，which can inhibit the growth of a variety of tumor cells. However ，its low solubility ，short half-life and poor stability limit its clinical application to a certain extent. In order to improve the above shortcomings and improve the bioavailability of gambogic acid ，many studies have used covalent binding and physical encapsulation methods to obtain a new gambogic acid delivery system with targeting ，high permeability ，stability， biocompatibility，in vivo long circulation and other properties ，such as polymer prodrug delivery system ，anoxic prodrug delivery system，magnetic field responsive prodrug delivery system ，multi environment sensitive prodrug delivery system ，bionic nano drug delivery system. This paper reviews the new drug delivery system and its characteristics of gambogic acid. The results show that the design of drug carrier has greatly improved the defects of gambogic acid ，and the introduction of more responsive groups into gambogic acid drug carrier may make it achieve better antitumor effect.

OBJECTIVE To explore the mechanism of joint injection of Caulophyllum robustum Maxim in the treatment of rheumatoid arthritis （RA）. METHODS The targets of main saponins in C. robustum Maxim were obtained from Swiss Target Prediction， and the RA treatment targets collected from the GeneCards and OMIM database were intercrossed to establish an interaction network based on network pharmacology. Gene ontology analysis and Kyoto Encyclopedia of Genes and Genomes （KEGG） pathway analysis were performed. RA model was established by injecting complete Freund’s adjuvant into the back of rabbits for verification. The arthritis index score， knee diameter and pain threshold of rabbits were compared. Pathological examination of rabbit synovial tissue was carried out. The levels of tumor necrosis factor α （TNF-α）， interleukin-1β （IL-1β） and IL-6 in rabbit serum and synovial fluid were detected. The phosphorylation levels of tyrosine protein Janus kinase 2 （JAK2） and signal transducer and activator of transcription 3 （STAT3） proteins in rabbit synovium were detected. RESULTS Network pharmacology identified 143 intersection targets between the drug and RA. After the construction of the “drug-component-target” network， the core components of the network were echinocystic acid， oleanolic acid， hederagenin， cauloside A and cauloside C， etc. Additionally， the top 10 core targets of PPI network were SRC， STAT3， MAPK1， EGFR， PIK3CA， MAPK3， GRB2， JUN， PTPN11 and JAK2. The results of KEGG pathway analysis showed that the JAK/STAT signaling pathway was mainly involved in the treatment of RA by joint injection of C. robustum Maxim. Results of validation test showed that compared with model group， joint injection of C. robustum Maxim could reduce the swelling of rabbit knee joint， relieve the hyperplasia of synovial layer， reduce the hyperplasia of lower connective tissue， and reduce the number of inflammatory cells and capillaries. The arthritis index score （excluding low-dose group of C. robustum Maxim）， knee diameter， the levels of TNF-α， IL-1β and IL-6 in serum and synovial fluid， and the protein phosphorylation levels of JAK2 and STAT3 were decreased significantly （P＜0.05 of P＜0.01）， while the pain threshold were reduced significantly （P＜0.01）. CONCLUSIONS The core components that may alleviate the inflammatory response of RA in joint injection of C. robustum Maxim could include echinocystic acid， oleanolic acid， hederagenin， cauloside A， and cauloside C. Its mechanism may be related to the inhibition of JAK/STAT signaling pathway and the reduction of inflammatory responses.
