Early gastric cancer detection and lesion segmentation based on deep learning and gastroscopic images.

Gastric cancer is a highly prevalent disease that poses a serious threat to public health. In clinical practice, gastroscopy is frequently used by medical practitioners to screen for gastric cancer. However, the symptoms of gastric cancer at different stages of advancement vary significantly, particularly in the case of early gastric cancer (EGC). The manifestations of EGC are often indistinct, leading to a detection rate of less than 10%. In recent years, researchers have focused on leveraging deep learning algorithms to assist medical professionals in detecting EGC and thereby improve detection rates. To enhance the ability of deep learning to detect EGC and segment lesions in gastroscopic images, an Improved Mask R-CNN (IMR-CNN) model was proposed. This model incorporates a "Bi-directional feature extraction and fusion module" and a "Purification module for feature channel and space" based on the Mask R-CNN (MR-CNN). Our study includes a dataset of 1120 images of EGC for training and validation of the models. The experimental results indicate that the IMR-CNN model outperforms the original MR-CNN model, with Precision, Recall, Accuracy, Specificity and F1-Score values of 92.9%, 95.3%, 93.9%, 92.5% and 94.1%, respectively. Therefore, our proposed IMR-CNN model has superior detection and lesion segmentation capabilities and can effectively aid doctors in diagnosing EGC from gastroscopic images.

Spatially Resolved, Error-Robust Multiplexed MicroRNA Profiling in Single Living Cells.

Simultaneous imaging of multiple microRNAs (miRNAs) in individual living cells is challenging due to the lack of spectrally distinct encoded fluorophores and non-cytotoxic methods. We describe a multiplexed error-robust combinatorial fluorescent label-encoding method, termed fluorophores encoded error-corrected labels (FluoELs), enabling multiplexed miRNA imaging in living cells with error-correcting capability. The FluoELs comprise proportional dual fluorophores for encoding and a constant quantitative single fluorophore for error-corrected quantification. Both are embedded in 260 nm core-shell silica nanoparticles modified with molecular beacon detection probes. The FluoELs are low cytotoxic and could accurately quantify and spatially resolve nine breast-cancer-related miRNAs and evaluate their coordination. The FluoELs enabled a single-cell analysis platform to evaluate miRNA expression profiles and the molecular mechanisms underlying miRNA-associated diseases.

A Nanodrug Coated with Membrane from Brain Microvascular Endothelial Cells Protects against Experimental Cerebral Malaria.

Human malaria is a global life-threatening infectious disease. Cerebral malaria (CM) induced by Plasmodium falciparum parasites accounts for 90% of malaria deaths. Treating CM is challenging due to inadequate treatment options and the development of drug resistance. We describe a nanoparticle formulation of the antimalarial drug dihydroartemisinin that is coated in a biomimetic membrane derived from brain microvascular endothelial cells (BMECs) and test its therapeutic efficacy in a mouse model of experimental cerebral malaria (ECM). The membrane-coated nanoparticle drug has a prolonged drug-release profile and enhanced dual targeting killing efficacy toward parasites residing in red blood cells (iRBCs) and iRBCs obstructed in the BMECs (for both rodent and human). In a mice ECM model, the nanodrug protects the brain, liver, and spleen from infection-induced damage and improves the survival rate of mice. This so-called nanodrug offers new insight into engineering nanoparticle-based therapeutics for malaria and other parasitic pathogen infections.

[Improving comprehensive retention rate of peppermint oil in freeze-dried preparation based on cyclodextrin inclusion technology].

The freeze-drying technique, characterized by low-temperature processing, is especially suitable for sensitive volatile oils with thermal instability. However, there are few studies focusing on the retention of volatile oils in the processing of freeze-dried preparations. This study evaluated the effects of different addition methods(adsorption, emulsification, solid dispersion, and inclusion) on the retention rate of the main components in peppermint oil, aiming to explore the application feasibility of freeze-dried preparations of volatile oils. Firstly, the addition method was determined based on the retention rates of menthol in four freeze-dried preparations. Secondly, an orthogonal test was designed to optimize the preparation process based on the characteristics of the preferred addition method. The results showed that the most suitable preparation form of peppermint oil was inclusion with beta-cyclodextrin(ß-CD), and the retention rate of menthol in freeze-drying was 86.36%. According to the two-step preparation process of inclusion and freeze-drying, we introduced the product of inclusion rate and retention rate, i.e., comprehensive retention rate, to determine the optimum processing parameters. The results showed that ß-CD/oil ratio of 7∶1, inclusion temperature of 40 ℃, and inclusion time of 2 h were the optimum processing parameters. The product prepared with these parameter had the comprehensive retention rate of 68.41%, retention rate of 92.53%, and inclusion rate of 73.93%. The inclusion compound was white powder with significantly increased solubility. The pre-paration process based on cyclodextrin inclusion in this study is stable and reliable and provides a new idea for ensuring the efficacy and stability of volatile components in freeze-dried preparations.

DNA Logic Circuits for Multiple Tumor Cells Identification Using Intracellular MicroRNA Molecular Bispecific Recognition.

The aberrant expression level of intracellular microRNAs (miRNAs) holds great promise for differentiating cell types at the molecular level. However, cell subtype discrimination based on a single miRNA molecular level is not sufficient and reliable. Herein, multiple identifiable and reporting modules are integrated into a single DNA circuit for multiple cancer cell subtypes identification based on miRNAs bispecific recognition. The DNA three-dimensional (3D) logic gate nano-hexahedron framework extends three recognition modules and three reporting modules to form three "AND" logic gates. Each Boolean operator "AND" returns an "ON" signal in the presence of bispecific miRNAs, simultaneously enabling three types of cell subtype identification. It not only enables the discrimination of cancer cells A549 and MCF-7 from normal cells NHDF but also successfully distinguishes different types of cancer cells. The bispecific intracellular miRNA controllable DNA circuit, with low signal-to-noise ratio, easily extends to various cell type discrimination by adjusting the miRNA species, provides huge opportunities for accurately differentiating multiple cell types at the molecular level.

[Molecular mechanism of Qishen Yiqi Dripping Pills in treating myocardial ischemia:a study based on HIF-1 signaling pathway].

Qishen Yiqi Dripping Pills(QSYQ) are used clinically to treat various myocardial ischemic diseases, such as angina pectoris, myocardial infarction, and heart failure; however, the molecular mechanism of QSYQ remains unclear, and the scientific connotation of traditional Chinese medicine(TCM) compatibility has not been systematically explained. The present study attempted to screen the critical pathway of QSYQ in the treatment of myocardial ischemia by network pharmacology and verify the therapeutic efficacy with the oxygen-glucose deprivation(OGD) model, in order to reveal the molecular mechanism of QSYQ based on the critical pathway. The key targets of QSYQ were determined by active ingredient identification and target prediction, and underwent pathway enrichment analysis and functional annotation with David database to reveal the biological role and the critical pathway of QSYQ. Cell counting Kit-8(CCK-8), lactate dehydrogenase(LDH), and Western blot tests were launched on high-content active ingredients with OGD cell model to reveal the molecular mechanism of QSYQ based on the critical pathway. The results of network pharmacology indicated that QSYQ, containing 18 active ingredients and 82 key targets, could protect cardiomyocytes by regulating biological functions, such as nitric oxide biosynthesis, apoptosis, inflammation, and angiogenesis, through TNF signaling pathway, HIF-1 signaling pathway, PI3 K-Akt signaling pathway, etc. HIF-1 signaling pathway was the critical pathway. As revealed by CCK-8 and LDH tests, astragaloside Ⅳ, salvianic acid A, and ginsenoside Rg_1 in QSYQ could enhance cell viability and reduce LDH in the cell supernatant in a concentration-dependent manner(P<0.05). As demonstrated by the Western blot test, astragaloside Ⅳ significantly down-regulated the protein expression of serine/threonine-protein kinase(Akt1) and hypoxia-inducible factor 1α(HIF-1α) in the HIF-1 signaling pathway, and up-regulated the protein expression of vascular endothelial growth factor A(VEGFA). Salvianic acid A significantly down-regulated the protein expression of upstream phosphatidylinositol-4,5-bisphosphate 3-kinase catalytic subunit alpha(PIK3 CA) and downstream HIF-1α of Akt1. Ginsenoside Rg_1 significantly down-regulated the expression of HIF-1α protein and up-regulated the expression of VEGFA. The therapeutic efficacy of QSYQ on myocardial ischemia was achieved by multiple targets and multiple pathways, with the HIF-1 signaling pathway serving as the critical one. The active ingredients of QSYQ could protect cardiomyocytes synergistically by regulating the targets in the HIF-1 signaling pathway to inhibit its expression.

Exploring the synergistic mechanism of Gegen Qinlian Decoction on the Wnt signaling pathway using an integrated strategy of network pharmacology and RNA-seq.

ETHNOPHARMACOLOGICAL RELEVANCE: Gegen Qinlian Decoction (GQD) (including: Puerariae lobatae (Willd.) Ohwi, radix; (short for Gengen) Glycyrrhiza uralensis Fisch., root and rhizome (short for Gancao), honeyed; Coptis chinensis Franch., rhizome (short for Huanglian); Scutellaria baicalensis Georgi, radix, boiled (short for S. baicalensis) has been widely used to treat inflammatory bowel disease (IBD) and colorectal cancer (CRC). To explore compatibility mechanism of GQD could be of advantage to investigate the complex principle of TCM, which might be conducive to the exploration of the modernization of TCM. AIM OF REVIEW: In this study, a strategy based on system pharmacology was constructed to uncover the multi-target regulation and compatibility mechanism of GQD on the Wnt signaling pathways. MATERIAL AND METHODS: The pharmacological network of GQD was constructed by TCMSP, DAVID, Uniprote database. The cell growth inhibitory effects of puerarin (PUE), wogonin (WOG), berberine (BER), and glycyrrhetinic acid (GLY) on SW480 cells were assessed using CCK-8 assay. The multi-target regulation and compatibility mechanism of combination PUE with GLY were examined by RNA-seq, HPLC-QQQ/MS, qRT- PCR and Western blot analysis. RESULTS: Network pharmacology analysis indicated that PUE, WOG, BER and GLY were the active components in GQD and had a synergistic effect on the targets of the Wnt signaling pathway. Additionally, pharmacological experiments revealed that WOG, BER, and GLY inhibited activity of colorectal cancer (CRC) cell lines SW480 cells, and that PUE only exhibited effective antitumour activity when combined with GLY. CTNNB1, CCND1 and SMAD4 were identified as synergistic targets inhibited by PUE-GLY. Moreover, PUE-GLY could influence the Wnt signaling pathway by upregulating GSK3B and downregulating CTNNB1 synergistically. It also showed that GLY could effectively increase the intracellular content of PUE based on HPLC-QQQ/MS analysis, and this process was achieved by influencing the targets of the membrane's pathway, such as cell adhesion molecules, focal adhesion, and tight junctions. CONCLUSION: GLY was revealed a multi-target mechanism, which could downregulate CTNNB1 as the active component and intervene in membrane proteins (CDH1, CADM1, ITGB2, ICAM1, ITGA1) as 'guide' in the formulae. Moreover, the mechanism of synergistic antitumour action of PUE (the active component of Monarch drug) and GLY (the active component of Guide drug) on the Wnt signaling pathway was explored systematically. It was a promising breakthrough for elucidating the scientific connotation of the compatibility of TCM formulae and provide a valuable and practicable methodology for clarifying the mechanisms of TCM.

Biodegradable FeWOx nanoparticles for CT/MR imaging-guided synergistic photothermal, photodynamic, and chemodynamic therapy.

The development of a simple and effective single constituent multifunctional nanotheranostic platform producing a multimodality diagnostic signal and curing effect is still a challenge. Herein, we synthesized simple and biodegradable FeWOx ternary oxide nanoparticles and modified their surface with RGD-PEG-NH2 (FeWOx-PEG-RGD NPs), whereby resulting NPs possessed a (T2/T1) switchable MRI/CT dual-modal imaging ability and synergistic photothermal therapy (PTT)/photodynamic therapy (PDT)/chemodynamic therapy (CDT) capacity. We showed that FeWOx-PEG-RGD NPs enabled tumor accumulation under a magnetic field drive and RGD-mediated tumor penetration and implemented PTT/PDT treatment under 980 nm laser irradiation. In an acidic tumor microenvironment (TME) with a high hydrogen peroxide (H2O2) expression, NPs degraded to release Fe3+ and Fe2+, triggering a Fenton reaction to generate ˙OH for CDT. The released Fe2+ led to T2/T1 signal conversion for tracing cancer therapy, while the high X-ray attenuation coefficient of W also made it a good CT contrast agent for guided therapy. Thus, the structurally simple FeWOx-PEG-RGD was capable of mediating (T2/T1-weighted) MR/CT two modal imaging-guided PTT/PDT/CDT synergic therapy with a high accuracy and superb anticancer efficiency. The simple, degradable, rapid-clearance, and multifunctional FeWOx-PEG-RGD NPs provide a novel, promising, and versatile nanotheranostic platform.

V2C Nanosheets as Dual-Functional Antibacterial Agents.

Antibiotic-resistant bacterial strains have been continuously increasing and becoming a supreme threat to public health globally. The nanoparticle-based photothermal treatment has emerged as a powerful tool to combat toxic bacteria. Photothermal agents (PTAs) with cost-effective and high photothermal conversion efficiency are highly desirable. Herein, we unite the green process for delamination of V2AlC to produce a high yield mass of two-dimensional (2D) V2C nanosheets (NSs) by using algae extracts and demonstrate their high antibacterial efficiency. The resultant V2C NSs present decent structural reliability and intrinsic antibacterial ability. Powerful near-infrared (NIR) absorption and extraordinary photothermal conversion proficiency make it a good PTA for the photothermal treatment of bacteria. The antibacterial efficiency evaluation indicated that V2C NSs could effectively kill both Gram-positive S. aureus and Gram-negative E. coli. About 99.5% of both types of bacteria could be killed with low-dose of V2C NSs suspension (40 µg/mL) with 5 min NIR irradiation due to the intrinsic antibacterial ability and photothermal effect of V2C NSs, which is much higher than previous reports on Ta4C3, Ti3C2, MoSe2, and Nb2C. This work expands the application of MXene V2C NSs for rapid bacteria-killing and would gain promising attention for applications in the sterilization industry.

Uniform palladium nanosheets for fluorimetric detection of circulating tumor DNA.

Fluorescence quenching property of two-dimensional (2D) nanosheets (NSs) have received extensively attention in the construction of novel biosensing platform. However, the heterogeneity of the wide-size distribution and inefficient fluorescence quenching capacity limit its wide practical applications. Herein, for the first time, we report a novel fluorescent biosensor based on uniform palladium NSs (Pd NSs) with excellent fluorescence quenching efficiency and differential affinity toward ssDNA versus dsDNA and combination with a pair of DNA detection probes with fluorophore for detecting circulating tumor DNA (ctDNA). The DNA detection probes are facilitated to adsorbed to the surface of Pd NSs, leading to efficient fluorescence quench. In the presence of target DNA, it can be linked by T4 DNA ligase to form long DNA duplex structures, which display weak affinity toward Pd NSs, producing the fluorescence recovery. The remarkable fluorescence quenching efficiency and ssDNA/dsDNA differential affinity of Pd NSs make it have a good detection ability without signal amplification. The result indicates that this facile but cost-effective strategy holds great promise in bioanalysis.

[Inhibitory effect of wogonin on human colorectal cancer cell SW480 based on network pharmacology].

Wogonin is a main effective component of Scutellaria baicalensis, with a significant anti-cancer activity. Recently, extensive studies focused on anti-cancer pharmacological effects of wogonin, but there were still a few studies on its molecular mechanism. Therefore, the molecular targets of its anti-cancer activity were still unclear. In this study, network pharmacology was applied to investigate the potential targets and molecular pathway of wogonin in inhibiting the growth of colorectal cancer. It indicated that Wnt/ß-catenin was a key pathway of wogonin on colorectal cancer. Then, pharmacology and molecular mechanism studies were performed according to network pharmacological results. Pharmacological results revealed that wogonin inhibited significantly the proliferation of SW480(P<0.001), with a concentration-dependent regularity in the range of 12.5-50 µmol·L~(-1). Additionally, wogonin could induce G_1 phase blocking of SW480 cells. Western blot was used to investigate the effect of wogonin on four characteristic proteins of Wnt/ß-catenin pathway. CTNNB1(ß-catenin), BIRC5(survivin) and GSK3 B were down-regulated significantly, while the expression level of BAX was up-regulated(P<0.05). In conclusion, wogonin could inhibit the proliferation of SW480 cells through Wnt/ß-catenin pathway. The feature protein CTNNB1(ß-catenin), BIRC5(survivin), GSK3 B and BAX were identified as the potential targets. This study illuminated the anti-cancer molecular mechanism and drug targets of wogonin, which provided a theoretical basis for anti-colon cancer drug discovery and clinical application.

An open source and reduce expenditure ROS generation strategy for chemodynamic/photodynamic synergistic therapy.

The therapeutic effect of reactive oxygen species (ROS)-involved cancer therapies is significantly limited by shortage of oxy-substrates, such as hypoxia in photodynamic therapy (PDT) and insufficient hydrogen peroxide (H2O2) in chemodynamic therapy (CDT). Here, we report a H2O2/O2 self-supplying nanoagent, (MSNs@CaO2-ICG)@LA, which consists of manganese silicate (MSN)-supported calcium peroxide (CaO2) and indocyanine green (ICG) with further surface modification of phase-change material lauric acid (LA). Under laser irradiation, ICG simultaneously generates singlet oxygen and emits heat to melt the LA. The exposed CaO2 reacts with water to produce O2 and H2O2 for hypoxia-relieved ICG-mediated PDT and H2O2-supplying MSN-based CDT, acting as an open source strategy for ROS production. Additionally, the MSNs-induced glutathione depletion protects ROS from scavenging, termed reduce expenditure. This open source and reduce expenditure strategy is effective in inhibiting tumor growth both in vitro and in vivo, and significantly improves ROS generation efficiency from multi-level for ROS-involved cancer therapies.

Bioinspired Framework Nucleic Acid Capture Sensitively and Rapidly Resolving MicroRNAs Biomarkers in Living Cells.

Quantifying intracellular microRNA (miRNA) is essential for diagnosis and prognosis of diseases because of its importance to the development and progression of complex diseases. The challenge is to develop methods that enable multiplex miRNAs detection in ultralow amounts and over broad concentration ranges. Inspired by the "tentacles" of an octopus, herein, we present a framework nucleic acid (FNA) capture for sensitive, rapid, and multiplexed imaging of miRNAs cancer biomarkers in living cells. The programmable FNA is designed using three DNA triangular prism (DTP) nanostructures carrying two pairs of metastable catalytic hairpin assembled (CHA) probes, AS1411 aptamer, and pendent biotinylated DNA strand in different vertexes and is further assembled via streptavidin to form the multivalent DTP (SA-DTP). The SA-DTP system acts as an octopus that captures the target cancer miRNAs quickly and delivers them preferentially among DTPs' "tentacles" in the SA-DTP system to produce strong, amplified fluorescence for detection. Precise multiplexed imaging of miRNA-155 and miRNA-21 cancer biomarkers' aberrant expression and dynamic change in different cells demonstrates the feasibility of both monitoring disease progression and evaluating therapeutic efficacy.

Algae Extraction Controllable Delamination of Vanadium Carbide Nanosheets with Enhanced Near-Infrared Photothermal Performance.

The two-dimensional (2D) vanadium carbide (V2 C) MXene has shown great potential as a photothermal agent (PTA) for photothermal therapy (PTT). However, the use of V2 C in PTT is limited by the harsh synthesis condition and low photothermal conversion efficiency (PTCE). Herein, we report a completely different green delamination method using algae extraction to intercalate and delaminate V2 AlC to produce mass V2 C nanosheets (NSs) with a high yield (90 %). The resulting V2 C NSs demonstrated good structural integrity and remarkably high absorption in near infrared (NIR) region with a PTCE as high as 48 %. Systemic in vitro and in vivo studies demonstrate that the V2 C NSs can serve as efficient PTA for photoacoustic (PA) and magnetic resonance imaging (MRI)-guided PTT of cancer. This work provides a cost-effective, environment-friendly, and high-yielding disassembly approach of MAX, opening a new avenue to develop MXenes with desirable properties for a myriad of applications.

Pd@Au Bimetallic Nanoplates Decorated Mesoporous MnO2 for Synergistic Nucleus-Targeted NIR-II Photothermal and Hypoxia-Relieved Photodynamic Therapy.

Bimetallic nanoparticles have received considerable attention owing to synergistic effect and their multifunctionality. Herein, new multifunctional Pd@Au bimetallic nanoplates decorated hollow mesoporous MnO2 nanoplates (H-MnO2 ) are demonstrated for achieving not only nucleus-targeted NIR-II photothermal therapy (PTT), but also tumor microenvironment (TME) hypoxia relief enhanced photodynamic therapy (PDT). The Pd@Au nanoplates present a photothermal conversion efficiency (PTCE) as high as 56.9%, superior to those PTAs activated in the NIR-II region such as Cu9 S5 nanoparticles (37%), Cu3 BiS3 nanorods (40.7%), and Au/Cu2-x S nanocrystals (43.2%). They further functionalize with transactivator of transcription (TAT) moiety for cell nuclear-targeting and biodegradable hollow mesoporous MnO2 (≈100 nm) loaded with photosensitizer Ce6 (TAT-Pd@Au/Ce6/PAH/H-MnO2 ) to construct a hierarchical targeting nanoplatform. The as-made TAT-Pd@Au/Ce6/PAH/H-MnO2 demonstrates good premature renal clearance escape ability and increased tumor tissue accumulation. It can be degraded in acidic TME and generate O2 by reacting to endogenous H2 O2 to relieve the hypoxia for enhanced PDT, while the released small TAT-Pd@Au nanoplates can effectively enter into the nucleus to mediate PTT. As a result, a remarkable therapeutic effect is achieved owing to the synergistic PTT/PDT therapy. This hierarchical targeting, TME-responsive, cytoplasm hypoxia relief PDT, and nuclear NIR-II PTT synergistic therapy can pave a new avenue for nanomaterials-based cancer therapy.

A controllable local drug delivery system based on porous fibers for synergistic treatment of melanoma and promoting wound healing.

A dual function system that inhibits tumor growth while promoting wound healing is very necessary for melanoma treatment since tumor killing and skin healing are two complementary and influential processes. Herein, a controllable local drug delivery system based on porous fiber membranes incorporated with CuS nanoparticles is designed for chemo-photothermal synergistic melanoma therapy and promoting wound healing. The porous structure on the fiber surface significantly increases the drug loading capacity of the membrane and the photothermal effect of incorporated CuS nanoparticles is used to control the drug release rate. Benefitting from the chemo-photothermal synergistic therapy, the composite membrane can effectively kill melanoma cells in vitro and inhibit tumor growth in vivo. Furthermore, the membrane can also significantly promote the cutaneous wound healing by providing mechanical support and releasing copper ions. Thus, this work provides new ideas for the development of multifunctional local treatment and postoperative care systems.

[Research on attributes of biopharmaceutics classification system for Chinese materia medica of baicalein in Gegen Qinlian Decoction environment].

For the effects of multi-component environment on the solubility and permeability of single components,and the problems of biopharmaceutical attribute classification of single components in the compound prescriptions environment,baicalein was used as the research object in this study to investigate the biopharmaceutic attributes of single-component and their traditional Chinese medicine( TCM) biopharmaceutic attributes in the multi-component environment of Gegen Qilian Decoction. Shaking flask method,intrinsic dissolution rate test and HPLC were used to determine solubility of baicalein. Markers specified by FDA were utilized as permeable boundary reference materials to verify the applicability of the single-pass intestinal perfusion method( SPIP),and the quantitative research on the permeability of baicalein was also conducted. It is concluded that baicalein could be categorized as BCS-Ⅱ drug based on its low solubility and high intestinal permeability values,and it may be categorized into CMMBCS-I in the multi-component environment of Gegen Qilian Decoction due to its poor solubility but enhanced solubility and permeability in compound environment. This study could provide verification ideas for clinical determination of the best human oral dose of baicalein,and provide the data basis for the study of biopharmaceutics classification system of Chinese materia medica( CMMBCS).

[Study on biopharmaceutics classification system of Chinese materia medica for Gegen Qinlians Tablets based on anti-inflammatory activity].

The research on biopharmaceutics classification system of Chinese materia medica( CMMBCS) should be finally implemented to the holistic research level of traditional Chinese medicine compounds,while the overall biopharmaceutical properties of traditional Chinese medicine compounds are not only the sum of solubility and permeability of each component. In this study,Gegen Qinlian Tablets was used as the research object,and the contents of 12 representative components,i.e. puerarin,daidzin,baicalin,daidzein,wogonoside,baicalein,wogonin,glycyrrhizic acid,coptisine hydrochloride,epiberberine,berberine hydrochloride and palmatine hydrochloride,were simultaneously determined by HPLC to obtain the mass weight of each component. The in vitro lipopolysaccharide( LPS)-induced RAW264. 7 cells inflammation model was established to investigate the anti-inflammatory effects of 12 representative components and obtain the efficacy weight of each component. In order to obtain the number of doses and effective permeability coefficient which can represent the overall biopharmaceutical properties of Gegen Qinlian Tablets,mass weight was combined with efficacy weight to integrate the solubility and permeability data of each component determined by typical shake flask method and in situ single pass intestinal perfusion model respectively. The results indicated that Gegen Qinlian Tablets should be categorized Ⅳ drug of the CMMBCS with low solubility and low permeability.
