Identification of quality markers of Gei Herba based on analytic hierarchy process-entropy weight method and network pharmacology / 中国中药杂志

Analytic hierarchy process(AHP)-entropy weight method(EWM) and network pharmacology were employed to identify the potential quality markers(Q-markers) of Gei Herba. According to the new concept of Q-markers in traditional Chinese medicine(TCM), the AHP-EWM was applied to quantitatively identify the Q-markers of Gei Herba. The AHP was used for the weight analysis of primary indicators(factor layer), and the EWM for the analysis of literature and experimental data of secondary indicators(control layer). In addition, network pharmacology was employed to build the "component-target-disease-efficacy" network for Gei Herba, and the components showing strong associations with the Qi-replenishing, spleen-invigorating, blood-tonifying, Yin-nourishing, lung-moistening, and phlegm-resolving effects of Gei Herba were screened out. According to the results of AHP-EWM and network pharmacology, four components, i.e., ellagic acid, gallic acid, gemin G, and gemin C, were finally identified as potential Q-markers of Gei Herba. In this study, the AHP-EWM and network pharmacology were employed to screen the Q-markers of Gei Herba, which provided ideas for the quantitative evaluation and identification of Q-markers of TCM.

Potential Medicinal Value of Rhein for Diabetic Kidney Disease / 中国结合医学杂志

Diabetic kidney disease (DKD) is the primary cause of mortality among diabetic patients. With the increasing prevalence of diabetes, it has become a major concern around the world. The therapeutic effect of clinical use of drugs is far from expected, and therapy choices to slow the progression of DKD remain restricted. Therefore, research on new drugs and treatments for DKD has been a hot topic in the medical field. It has been found that rhein has the potential to target the pathogenesis of DKD and has a wide range of pharmacological effects on DKD, such as anti-nephritis, decreasing blood glucose, controlling blood lipids and renal protection. In recent years, the medical value of rhein in the treatment of diabetes, DKD and renal disease has gradually attracted worldwide attention, especially its potential in the treatment of DKD. Currently, DKD can only be treated with medications from a single symptom and are accompanied by adverse effects, while rhein improves DKD with a multi-pathway and multi-target approach. Therefore, this paper reviews the therapeutic effects of rhein on DKD, and proposes solutions to the limitations of rhein itself, in order to provide valuable references for the clinical application of rhein in DKD and the development of new drugs.

Research on Q-markers of Polygoni Perfoliati Herba based on analytic hierarchy process-entropy weight method and fingerprints / 中国中药杂志

The potential quality markers(Q-markers) of Polygoni Perfoliati Herba were studied based on analytic hierarchy process(AHP)-entropy weight method(EWM), network pharmacology, and spectrum-effect relationship analysis. The AHP-EWM was used for quantitative identification of the Q-markers. To be specific, AHP was applied for the weight analysis of the validity, testability, and specificity of the first-level indexes, and EWM for the analysis of the second-level indexes supported by literature and experimental data. Based on literature and network pharmacology, the validity analysis was to study the component-target-disease-efficacy network, and select the components with the strongest correlation with the efficacy of clearing heat and removing toxin, diuresis and alleviating edema, and relieving cough. For the testability analysis, the high performance liquid chromatography(HPLC) and literature research were used to determine the 10 components in Polygoni Perfoliati Herba, and the fingerprints of Polygoni Perfoliati Herba were established at the same time. The specificity analysis was based on the statistics of the number of plants in which the components existed. Thereby, the 11 compounds: quercetin, oleanolic acid, ellagic acid, gallic acid, kaempferol, rutin, esculetin, quercetin-3-O-glucuronide, ursolic acid, protocatechuic acid, and ferulic acid, were identified as potential Q-markers. The 11 compounds were identified to have high anti-inflammatory activity, indicating that the 11 Q-markers may be the functional material basis. The result in this study is expected to serve as a reference for the quality control of Polygoni Perfoliati Herba.

Research Progress on Compatibility Mechanism of Coptidis Rhizoma-Euodiae Fructus： A Review / 中国实验方剂学杂志

Herb pair， a common form of compounding in Chinese medicinal prescriptions， reflects the experience of pharmacists in clinical medication in the past. It is characterized by simple composition while has the basic characteristics of Chinese medicine compounding. The combination of two medicinal herbs can enhance effect or reduce toxicity. Coptidis Rhizoma （CR） has the effects of clearing heat， drying dampness， purging fire， and removing toxin. Euodiae Fructus （EF） is acrid， bitter， and hot-natured， which can not only warm the Yang Qi in spleen and stomach to dissipate cold and relieve pain， but also descend stomach Qi and prevent vomiting. Furthermore， it can warm the liver and kidney. CR and EF form a typical cold-heat herb pair， which oppose and yet also complement each other. Specifically， their cold and heat natures interact with each other to clear liver fire， harmonize stomach for descending adverse Qi， relieve depression， and dissipate mass. CR clears the intestine and stops dysentery， while EF warms the middle and promotes the circulation of Qi. The combination of them can thus clear heat， dry dampness， and relieve pain. Modern pharmacological studies have demonstrated that CR-EF has not only significant efficacy against digestive system diseases but also good anti-cancer， anti-inflammatory， anti-ulcer， and lipid-lowering activities. Therefore， the article summarized the effect enhancement and toxicity reduction of the herb pair at the levels of cellular molecule， isolated organ， and whole animal， and clarified the mechanism of its pharmacological action. It will provide a theoretical basis for further development and clinical use of the herb pair.

Quantitative identification of TCM Q-markers based on analytical hierarchy and the entropy weight comprehensive method by taking Shaoyao Gancao decoction as an example / 药学学报

The quality markers (Q-markers) of traditional Chinese medicine (TCM) have become a topic of interest in TCM research in recent years. Nonetheless, there is still no consensus on how to scientifically characterize TCM Q-markers. Our study establishes an identification method for TCM Q-markers based on the analytical hierarchy process (AHP) and the entropy weight comprehensive method. By constructing an evaluation system encompassing the target layer, the factor layer and the control layer, AHP can be used to analyze the weight of three core TCM quality attributes, including effectiveness, testability and specificity. Following that, the entropy weight method is employed to analyze the specific indicators for each attribute based on the literature and experimental data. Finally, the comprehensive weight of each index is obtained by combining the two weights, and the comprehensive weight and the specific value of each component is multiplied and summed to obtain the integrated score ranking, and thereby identify the TCM Q-markers. Taking Shaoyao Gancao decoction as an example, the analysis revealed that the top 8 components are as follows: paeoniflorin > quercetin > albiflorin > glycyrrhizic acid > naringenin > liquiritin > oxypaeoniflorin > benzoylpaeoniflorin, and can be identified as Q-markers of Shaoyao Gancao decoction. This study not only provides support for the establishment of quality standards and process quality control of TCM formulae, but also provides innovative ideas and methods for quantitative evaluation and accurate identification of TCM Q-markers.

Identification of quality markers of Qixuehe Capsules based on analytic hierarchy process and entropy weight methods / 中国中药杂志

Qixuehe Capsules is a compound Chinese patent medicine developed for treating the disorder of Qi and blood(a common etiology of gynecological disease), which has remarkable effects on smoothing liver and regulating Qi, activating blood circulation, and relieving pain. However, due to its complex prescriptions(15 herbs) and multiple effects, the quality control of Qixuehe Capsules has always been a bottleneck problem limiting its sustainable development. Therefore, this study adopted the traditional Chinese medicine Q-markers quantitative identification system established previously by our research group based on the combination of analytic hierarchy process and entropy weight methods. With the different effects of Qixuehe Capsules as the entry point, the comprehensive scores of chemical ingre-dients in Qixuehe Capsules under the items of effectiveness(smoothing liver and regulating qi, activating blood circulation, and relieving pain), testability and specificity were calculated and integrated, respectively. Subsequently, through the analysis of compatibility relationship of Qixuehe Capsules, 15 active ingredients with high comprehensive scores were found to be the top Q-mar-kers of Qixuehe Capsules, including ferulic acid, quercetin, caffeic acid, kaempferol, rutin, Z-ligustilide, senkyunolide Ⅰ, vanillic acid, protocatechuic acid, chlorogenic acid, rosmarinic acid, senkyunolide A, gallic acid, tetrahydropalmatine and eugenol. Collectively, this study not only provided scientific evidence for further research on the improvement and standardization of quality standards of Qixuehe Capsules but also provided methodological references for the quantitative identification of Q-markers of multi-effect traditional Chinese medicine formulae.

Anterior Gradient 3 Promotes Breast Cancer Development and Chemotherapy Response / Journal of the Korean Cancer Association, 대한암학회지

Purpose@#Anterior gradient 3 (AGR3) belongs to human anterior gradient (AGR) family. The function of AGR3 on cancer remains unknown. This research aimed to investigate if AGR3 had prognostic values in invasive ductal carcinoma (IDC) of breast cancer and could promote tumor progression. @*Materials and Methods@#AGR3 expression was detected in breast benign lesions, ductal carcinoma in situ and IDC by immunohistochemistry analysis. AGR3’s correlations with clinicopathological features and prognosis of IDC patients were analyzed. By cell function experiments, collagen gel droplet-embedded culture drug sensitivity test and cytotoxic analysis, AGR3’s impacts on proliferation, invasion ability, and chemotherapeutic drug sensitivity of breast cancer cells were also detected. @*Results@#AGR3 was up-regulated in luminal subtype of histological grade I-II of IDC patients and positively correlated with high risks of recurrence and distant metastasis. AGR3 high expression could lead to bone or liver metastasis and predict poor prognosis of luminal B. In cell lines, AGR3 could promote proliferation and invasion ability of breast cancer cells which were consistent with clinical analysis. Besides, AGR3 could indicate poor prognosis of breast cancer patients treated with taxane but a favorable prognosis with 5-fluoropyrimidines. And breast cancer cells with AGR3 high expression were resistant to taxane but sensitive to 5-fluoropyrimidines. @*Conclusion@#AGR3 might be a potential prognostic indicator in luminal B subtype of IDC patients of histological grade I-II. And patients with AGR3 high expression should be treated with chemotherapy regimens consisting of 5-fluoropyrimidines but no taxane.

Establishment and Clinical Application of Flow Cytometric Immunobead Array in Detecting Plasma von Willebrand Factor Antigen / 中国实验血液学杂志

OBJECTIVE@#To establish a novel flow cytometric immunobead array (FCIA) for detecting plasma von Willebrand factor antigen (vWF:Ag), and to analyze the clinical value of FCIA in predicting the prognosis of patients with ischemic stroke (IS).@*METHODS@#Anti-human vWF monoclonal antibody SZ29 IgG was coated on microspheres overnight, the diluted plasma was added after blocking, then incubated with FITC-conjugated sheep-anti-human vWF IgG polyclonal antibody, and finally detected by flow cytometry. The plasma vWF in 21 case of von Willebrand disease (vWD) and 105 controls (CTL) were detected by FCIA and ELISA, so as to carry out methodological assessment. Plasma vWF:Ag of 61 IS patients was detected by FCIA and the data of prognosis followed-up for 2-year were collected.@*RESULTS@#The linear fitting of FCIA was good (R2=0.99) without significant difference between FCIA and ELISA. The Bland-Altman bias was 1.12% with 95% limits of agreement that spanned from -45.06% to 47.30%, and the slope of the linear regression was 0.97 (r=0.86, P＜0.01). Importantly, the FCIA method was faster than ELISA, and superior to the ELISA in the detection of low levels of vWF:Ag. The levels of vWF:Ag, vWF:GPIbR and vWF:CB in IS patients were significantly higher than those in healthy controls (Z=8.36, 8.71, 6.22, respectively, P＜0.01).@*CONCLUSION@#The FCIA for detecting plasma vWF:Ag is not only an effective supplement to ELISA, but also the efficiency is faster and more sensitive, thus improves the diagnosis of type 3 vWD. Elevated levels of vWF: Ag in IS patients indicate the poor recovery of daily activities and prognosis.

OBJECTIVE@#To establish a novel flow cytometric immunobead array (FCIA) for detecting plasma von Willebrand factor activity (vWF:GPIbR) and apply it in ischemic stroke (IS).@*METHODS@#Microspheres coated with anti-human platelet glycoprotein Ibα (GPIbα) monoclonal antibody SZ151 IgG, were incubated with recombinant fragment of GPIbα, then added ristocetin and plasma, finally incubated with FITC-conjugated sheep-anti-human vWF IgG polyclonal antibody, and detected by flow cytometry. vWF antigen (vWF:Ag), vWF:GPIbR, and vWF collagen binding assay (vWF:CB) were also included for evaluating vWF levels in IS patients.@*RESULTS@#The intra-assay coefficient variations (CVs) and inter-assay CVs of FCIA were 7.7% and 13.5%, respectively. The slope of the linear regression was 0.9739 (r=0.855, P<0.001), and the Bland-Altman bias was 9.95%, indicating a good correlation between FCIA and ELISA. The FCIA had better sensitivity, specificity and accuracy as compared with those by ELISA (P<0.05). The levels of vWF:Ag, vWF:GPIbR and vWF:CB in IS patients were significantly higher in comparison with those in healthy controls (H=7.8, 6.4, 6.2, respectively, P<0.01), the level of vWF:GPIbR in IS patients positively correlated with levels of vWF:Ag, high-sensitivity C-reactive protein, Autar score and hospitalization time.@*CONCLUSION@#The FCIA for detecting plasma vWF:GPIbR is more specific and accurate than ELISA. The vWF:GPIbR is involved in the paroxysm of IS, which could be used to evaluate the risk of thrombosis in IS patients.

Effect of Ershiwuwei Zhenzhu Tablets on Microvascular Function in Zebrafish / 中国实验方剂学杂志

Objective:To explore the effect of Ershiwuwei Zhenzhu tablets (EZT) on microvascular function. Method:The zebrafish models of thrombosis, microvascular defect and vascular endothelial injury were induced by using arachidonic acid, simvastatin and ponatinib respectively, and treated with EZT, astragaloside or asprin. To evaluate the protective effect of EZT on vascular endothelium and its effect on thrombus formation, zebrafish heart output and blood flow velocity were counted, and the vascular area of the zebrafish intestine and the intervascular diameter were calculated. The thrombus in the tail vein was observed under microscope. Result:Compared with model group,EZT improved the cardiac output (PP-1, and promoted angiogenesis in zebrafish at concentrations of 0.11, 0.33, 1 mg·L-1. Compared with the model group, the vascular diameter of the zebrafish internode was significantly increased at the concentrations of 33 mg·L-1 (P-1 (P-1(PConclusion:EZT could improve microvascular dysfunction, and its mechanism may be related to the reduction of vascular endothelial damage to promote its angiogenesis and the improvement of microvascular hemodynamics to reduce thrombus formation.
