ABSTRACT

Objective:To investigate the renoprotective effects that Sanjiao Qushi prescription ameliorates cationic bovine serum albumin (C-BSA) induced membranous nephropathy(MN) in mice model and its influence on nuclear factor erythroid-2-related factor-2(Nrf2)/heme oxygenase-1(HO-1) signaling pathway. Method:Sixty female BALB/c mice were randomly divided into the normal group(<italic>n</italic>=10) and the model group(<italic>n</italic>=50). The mice in the model group received C-BSA injection via tail vein (6.5 mg·kg<sup>-1</sup>). The mice that were successfully modeled were randomized into the model group, the low dose Sanjiao Qushi prescription group(3.71 g·kg<sup>-1</sup>), the high dose Sanjiao Qushi prescription group(7.42 g·kg<sup>-1</sup>) and benazepril hydrochloride group(1.3 mg·kg<sup>-1</sup>). And they were administered with the corresponding medicine by gavage once a day for four consecutive weeks. 24 hour-urine protein quantitation were performed before C-BSA injection and after C-BSA injection as well as the medicine gavage. When the treatment was finished, all of the mice were sacrificed and the biochemical indicators such as serum creatinine(SCr), blood urea nitrogen(BUN), triglyceride(TG), total cholesterol(TC), total protein(TP) and albumin(Alb) were measured. And the renal pathological morphology changes were observed by light microscope with hematoxylineosin(HE), Masson and periodic acid-silver metheramine(PASM) staining. The deposition of immunoglobulin G(IgG) in the glomerulus was detected by fluorescence microscope. The expression of reactive oxygen species (ROS) of kidney was detected by fluorescence immunoassay. The protein expression levels of Nrf2 in cell nucleus and cytoplasm and the downstream protein factors HO-1 and NADH quinone acceptor oxidoreductase 1(NQO1) were detected by Western blot. Result:Compare to normal group, the levels of 24 hour-urine protein quantitation, TG and TC significantly increased in model group(<italic>P</italic><0.01), while TP and Alb levels significantly decreased(<italic>P</italic><0.01). The model group exhibited enlarged volume of glomerular, significantly thickened glomerular basement membrane(GBM), fuchsinophilic protein deposition and spike formation through light microscope. Immunofluorescence staining for the model group exhibited granular deposition of IgG along the capillary wall. The expression of ROS in kidney significantly increased(<italic>P</italic><0.01). The protein expression levels of Nrf2 in cell nucleus significantly increased(<italic>P</italic><0.01), while Nrf2 in cytoplasm significantly decreased(<italic>P</italic><0.01).The protein expression levels of HO-1 and NQO1 significantly increased(<italic>P</italic><0.01). Compared to model group, the levels of 24 hour-urine protein quantitation, TG and TC significantly decreased in each treated group(<italic>P</italic><0.01), TP and Alb levels significantly increased(<italic>P</italic><0.05,<italic>P</italic><0.01). The pathological damages alleviated obviously. The expression of ROS in kidney significantly decreased(<italic>P</italic><0.01). The protein expression levels of Nrf2 in cell nucleus significantly decreased(<italic>P</italic><0.01), while Nrf2 in cytoplasm significantly increased(<italic>P</italic><0.05,<italic>P</italic><0.01). The protein expression levels of HO-1 and NQO1 significantly increased(<italic>P</italic><0.01). Conclusion:Sanjiao Qushi prescription worked on MN mice possibly by regulating related proteins in the Nrf2/HO-1 signaling pathway and relieving oxidative stress, thus decreasing 24 hour-urine protein and blood lipid, increasing serum protein, and alleviating the pathological damages to protect renal function and delay progress of the disease.

ABSTRACT

To investigate the potential molecular mechanism of the combination of Platycodonis Radix and Lilii Bulbus with the homology of medicine and food in the treatment of pneumonia by means of network pharmacology and in vitro verification experiment. Under the condition of bioavailability(OB)≥30% and drug-like(DL)≥0.18, the active components of Platycodonis Radix and Lilii Bulbus were screened in TCMSP database; the prediction targets of active components were searched from TCMSP, DrugBank and other databases, and the potential targets of pneumonia were obtained through GeneCards and OMIM database. The common targets were obtained by the intersection of drug and disease targets. The PPI network of common targets was constructed by STRING 11.0, and the core targets were obtained by topological analysis. Then the core targets received GO and KEGG analysis with use of WebGestalt and Metascape. The "component-target-pathway" network was constructed with the help of Cytoscape 3.7.1 software, and the component-target molecular docking verification was carried out with Discovery Studio 2016 software. Finally, the core targets and pathways were preliminarily verified in vitro. In this study, 12 active components were screened, 225 drug prediction targets and 420 potential diseases targets were obtained based on data mining method, and 14 core targets were obtained by topological analysis, including TNF, MMP9, AKT1, IL4 and IL2. The enrichment results of GO and KEGG showed that "Platycodonis Radix and Lilii Bulbus" drug pair may regulate inflammation, cell growth and metabolism by acting on 20 key signaling pathways such as TNF and IL-17, thereby exerting anti-pneumonia effects. The results of molecular docking showed that 12 active components had good binding ability with 14 core targets. In vitro experiment results showed that the core components of "Platycodonis Radix and Lilii Bulbus" drug pair could inhibit the expression of MMP9 and TNF-α by regulating TNF signal pathway. This study confirmed the scientificity and reliability of the prediction results of network pharmacology, and preliminarily revealed the potential molecular mechanism of the compatibility of Platycodonis Radix and Lilii Bulbus in the treatment of pneumonia. It provides a novel insight on systematically exploring the mechanism of the compatible use of Platycodonis Radix and Lilii Bulbus, and has a certain reference value for the research, development and application of new drugs.

Method:UPLC-Q/TOF-MS was used to detect the chemical constituents of Aurantii Fructus, chromatography separation was achieved on an ACQUITY UPLC BEH C18 column (2.1 mm×100 mm, 1.7 μm), and gradient elution was performed with 0.1% formic acid aqueous solution (A)-0.1% formic acid acetonitrile solution (B) as mobile phase (0-10 min, 5%-35%B; 10-18 min, 35%-75%B; 18-21 min, 75%-100%B; 21-24 min, 100%B; 24-24.1 min, 100%-5%B; 24.1-28 min, 5%B). Data acquisition was carried out in electrospray ionization (ESI) under the positive ion mode, the scanning range was m/z 50-1 200. The chemical constituents in methanol extract of Aurantii Fructus were identified according to reference substance, relative molecular weight, mass spectrometric cleavage rule and literature information. SIMCA-P 13.0 software was used to establish principal component analysis (PCA) model and partial least squares-discriminant analysis (PLS-DA) model of Aurantii Fructus processed products, PCA score plot, PLS-DA loading plot and variable importance in the protection (VIP) values were obtained to screen the material basis for the main differences before and after processing of Aurantii Fructus. Result:A total of 54 chemical components were identified by UPLC-Q/TOF-MS. PCA indicated that there were significant differences among different groups of Aurantii Fructus processed by different methods. A total of 14 chemical components with VIP value >1 were screened by PLS-DA as the main chemical markers for the differences before and after processing, including hesperidin, poncirin, narirutin, etc. The comprehensive weighted score showed that the content of effective components in Aurantii Fructus processed with honey bran was the highest. Conclusion:The contents of chemical constituents in Aurantii Fructus before and after processing are significantly changed. Flavonoids are the most important compounds to distinguish different processed products of Aurantii Fructus. Aurantii Fructus processed with honey bran is the dominant variety.

ABSTRACT

<p><b>OBJECTIVE</b>To observe the clinical efficacy of Quyu Jiedu Recipe (, QJR) in treating endometriosis (EM), and to explore the levels of vascular endothelial growth factor (VEGF) and cell proliferative nucleoprotein antigen (Ki-67), their changes before and after treatment and the clinical significance in the trial.</p><p><b>METHODS</b>Fifty patients of EM were randomly assigned to two groups. The 26 patients in the QJR group were treated with QJR, and the 24 patients in the gestrinone (GT) group with gestrinone. Besides, a normal control group with 20 healthy women was set up. The therapeutic effects in the two treated groups were compared. Expressions of VEGF and Ki-67 in eutopic endometrium of all subjects (with both patients and healthy women at the median secretive phase) were determined with immunohistochemical stain before treatment, and the determination in the two treated groups was repeated after 3-month treatment in the same phase.</p><p><b>RESULTS</b>Before treatment, the VEGF and Ki-67 expression positive rates and their mean optic density (MOD) were higher in patients than in healthy women (P<0.05). After treatment, the positive rate and MOD of VEGF expression lowered significantly than before treatment (P<0.05), but those of Ki-67 changed insignificantly, and comparison between the two treated groups showed no significant difference (P>0.05).</p><p><b>CONCLUSION</b>QJR could markedly improve the symptoms of menorrhagia and menstrual disorder, and its mechanism might be related with the lowering of eutopic endometrial VEGF expression. VEGF and Ki-67 show a high expression in eutopic endometrium of patients with EM.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To observe the mechanism of Quyujiedu (QYJD, a method for removing stasis and detoxicating) in treating endometriosis of stasis-toxic syndrome type.</p><p><b>METHODS</b>Clinical study: Sixty patients were randomly divided into two groups, the treated group treated with QYJD and the control group treated with Danazol. The changes of clinical symptoms, physical signs, pregnancy rate, as well as levels of interleukin-1 (IL-1), interleukin-6 (IL-6) and endometrial antibody (EMAb) in them before and after treatment were observed. Experimental study: Sixty rats were established into endometriosis model, and randomly divided into the QYJD treated group, the Danazol treated group for positive control and the untreated group for negative control to observe the expression of Bax.</p><p><b>RESULTS</b>Clinical study showed that in the treated group and the control group, after treatment, dysmenorrhea score were 2.40 +/- 1.85 and 3.47 +/- 2.03, the menoxenia score 1.67 +/- 2.04 and 3.73 +/- 1.72 (P < 0.05), and the pregnancy rate 63.2% and 23.5% respectively, the difference between them was significant (all P < 0.05). Both of the two treatments can rectify immunity, reduce levels of IL-1 and IL-6, and lower the positive rate of EMAb. Experimental study showed that QYJD could improve the expression of Bax in ectopic endometrium, but could not affect the on-side expression of Bax in endometrium and muscle tissue.</p><p><b>CONCLUSION</b>QYJD is effective in improving the stasis-toxic syndrome of endometriosis, its mechanism related with the regulation of the immune condition and the promotion of cell apoptosis in ectopic endometrium, indicating that QYJD is an effective remedy for endometriosis of stasis-toxic syndrome type.</p>
