Mechanism of action of Shen-Fu decoction on cardiogenic shock based on network pharmacology and experimental validation / 中国药理学通报

Aim To investigate the mechanism of action of Shen-Fu decoction in the prevention and treatment of cardiogenic shock based on network pharmacology and animal experiments. Methods The relevant targets and signaling pathways of cardiogenic shock of Shen-Fu decoction were predicted by network pharmacology, and a cardiogenic shock rat model was created by coronary artery ligation. Before modeling, rats were given the appropriate dose of Shen-Fu decoction or saline by gavage for 14 days according to the group, and real-time mean arterial pressure (MAP) changes were recorded after successful modeling. HE method was used to detect the myocardial histopathological changes of cardiogenic shock. TUNEL method was employed to detect rat myocardial cell apoptosis, and Western blotting was applied to determine the expression levels of rat myocardial Bax, Bcl-2, caspase-3, cleaved caspase-3 proteins. Results A total of 51 potential active ingredients of Shen-Fu decoction were screened out by network pharmacology, 80 targets of co-action with cardiogenic shock, and 43 core targets of close relationship between proteins, and GO enrichment analysis revealed that the core proteins were involved in the biology process (BP), mainly involving positive regulation of apoptotic process. KEGG enrichment analysis showed signaling pathways involving atherosclerosis-related, apoptosis and other signaling pathways. The results of animal model validation showed that Shen-Fu decoction could increase the shock blood pressure of rats with cardiogenic shock and alleviate the pathological changes of myocardial tissue, reduce the degree of apoptosis of rat cardiomyocytes, reduce the expression level of caspase-3, cleaved caspase-3 and Bax protein in rat myocardial tissue, and improve the expression level of Bcl-2 protein in myocardial tissue of rats. Conclusions The potential active ingredient of Shen-Fu decoction may play a role in the prevention and control of cardiogenic shock rats by acting on the target Bax, Bcl-2 to regulate the apoptosis signaling pathway of cardiomyocytes.

Objective: To fabricate TiO2 nanotube material functionalized by antimicrobial peptide LL-37, and to explore its effects on biological behaviors such as adhesion and migration of human keratinocytes (HaCaT) and its antibacterial properties. Methods: The TiO2 nanotube array (NT) was constructed on the surface of polished titanium (PT) by anodization, and the antimicrobial peptide LL-37 was loaded on the surface of TiO2 nanotube (LL-37/NT) by physical adsorption. Three samples were selected by simple random sampling in each group. Surface morphology, roughness, hydrophilicity and release characteristics of LL-37 of the samples were analyzed with a field emission scanning electron microscope, an atomic force microscope, a contact angle measuring device and a microplate absorbance reader. HaCaT cells were respectively cultured on the surface of three groups of titanium samples. Each group had 3 replicates. The morphology of cell was observed by field emission scanning electron microscope. The number of cell adhesion was observed by cellular immunofluorescence staining. Cell counting kit-8 (CCK-8) assay was used to detect cell proliferation. Wound scratch assay was used to observe the migration of HaCaT. The above experiments were used to evaluate the effect of each group on the biological behavior of HaCaT cells. To evaluate their antibacterial effects, Porphyromonas gingivalis (Pg) was respectively inoculated on the surface of three groups of titanium samples. Each group had 3 replicates. The morphology of bacteria was observed by field emission scanning electron microscope. Bacterial viability was determined by live/dead bacterial staining. Results: A uniform array of nanotubes could be seen on the surface of titanium samples in LL-37/NT group, and the top of the tube was covered with granular LL-37. Compared with PT group [the roughness was (2.30±0.18) nm, the contact angle was 71.8°±1.7°], the roughness [(20.40±3.10) and (19.10±4.11) nm] and hydrophilicity (the contact angles were 22.4°±3.1° and 25.3°±2.2°, respectively) of titanium samples increased in NT and LL-37/NT group (P<0.001). The results of in vitro release test showed that the release of antimicrobial peptide LL-37 was characterized by early sudden release (1-4 h) and long-term (1-7 d) slow release. With the immunofluorescence, more cell attachment was found on NT and LL-37/NT than that on PT at the first 0.5 and 2.0 h of culture (P<0.05). The results of CCK-8 showed that there was no significant difference in the proliferation of cells among groups at 1, 3 and 5 days after culture. Wound scratch assay showed that compared with PT and NT group, the cell moved fastest on the surface of titanium samples in LL-37/NT group at 24 h of culture [(96.4±4.9)%] (F=35.55, P<0.001). A monolayer cells could be formed and filled with the scratch in 24 h at LL-37/NT group. The results of bacterial test in vitro showed that compared with the PT group, the bacterial morphology in the NT and LL-37/NT groups was significantly wrinkled, and obvious bacterial rupture could be seen on the surface of titanium samples in LL-37/NT group. The results of bacteria staining showed that the green fluorescence intensity of titanium samples in LL-37/NT group was the lowest in all groups (F=66.54,P<0.001). Conclusions: LL-37/NT is beneficial to the adhesion and migration of HaCaT cells and has excellent antibacterial properties, this provides a new strategy for the optimal design of implant neck materials.

Identification and verification of key salt-tolerant amino acid sites of banana MaNHX5 / 生物工程学报

In order to improve the salt tolerance of banana NHX genes, we cloned a MaNHX5 gene from Musa acuminata L. AAA group and predicted the key salt-tolerant amino acid sites and mutant protein structure changes of MaNHX5 by using bioinformatics tools. The 276-position serine (S) of MaNHX5 protein was successfully mutated to aspartic acid (D) by site-directed mutagenesis, and the AXT3 salt-sensitive mutant yeast was used for a functional complementation test. The results showed that after the mutated MaNHX5 gene was transferred to AXT3 salt-sensitive mutant yeast, the salt tolerance of the mutant yeast was significantly improved under 200 mmol/L NaCl treatment. It is hypothesized that Ser276 of MaNHX5 protein plays an important role in the transport of Na+ across the tonoplast.

Label-free quantitative proteomics reveals fibrinopeptide B and heparin cofactor II as potential serum biomarkers in respiratory syncytial virus-infected mice treated with Qingfei oral liquid formula / 中国天然药物

Respiratory syncytial virus (RSV) is a leading cause of acute lower respiratory tract infections. Qingfei oral liquid (QFOL), a traditional Chinese medicine, is widely used in clinical treatment for RSV-induced pneumonia. The present study was designed to reveal the potential targets and mechanism of action for QFOL by exploring its influence on the host cellular network following RSV infection. We investigated the serum proteomic changes and potential biomarkers in an RSV-infected mouse pneumonia model treated with QFOL. Eighteen BALB/c mice were randomly divided into three groups: RSV pneumonia model group (M), QFOL-treated group (Q) and the control group (C). Serum proteomes were analyzed and compared using a label-free quantitative LC-MS/MS approach. A total of 172 protein groups, 1009 proteins, and 1073 unique peptides were successfully identified. 51 differentially expressed proteins (DEPs) were identified (15 DEPs when M/C and 43 DEPs when Q/M; 7 DEPs in common). Classification and interaction network showed that these proteins participated in various biological processes including immune response, blood coagulation, complement activation, and so forth. Particularly, fibrinopeptide B (FpB) and heparin cofactor II (HCII) were evaluated as important nodes in the interaction network, which was closely involved in coagulation and inflammation. Further, the FpB level was increased in Group M but decreased in Group Q, while the HCII level exhibited the opposite trend. These findings not only indicated FpB and HCII as potential biomarkers and targets of QFOL in the treatment of RSV pneumonia, but also suggested a regulatory role of QFOL in the RSV-induced disturbance of coagulation and inflammation-coagulation interactions.

Regulation of BuShen ZhuYun Decotion on gonadotropin in rat pituitary cells / 医学研究生学报

Objective The mechanism of luteal phase defect remains unclear. To investigate the mechanism of BuShen ZhuYun Decoction on the gonadotropin secretion in the pituitary gland, we observed the effects of medicated serum of BuShen ZhuYun Decotion on the secretion of gonadotropin-follicle-stimulating hormone (FSH) and luteotropic hormone (LH) in rat pituitary cells.Methods The BuShen ZhuYun Decotion was administered to the female SD rats by gavage to prepare the serum containing BuShen ZhuYun Decoction. The CCK-8 method was used to detect the effect of cetrorelix acetate powder for injection, medicated serum and gonadotropin releasing hormone (GnRH) on cell activity. In the maximum non-toxic concentration, we used cetrorelix acetate powder for injection to block the GnRH receptor (GnRHR) in pituitary cells and established the GnRHR antagonistic model. Then we treat the model group with medicated serum (model group). Moreover, we established the blank group (normal pituitary cells), the cetrorelix group (intervented with cetrorelix for 6 hours), and medicated serum group (intervented with medicated serum for 24 hours). 20nmol/L GnRH was used to stimulate cells for 6h. The contents of FSH and LH in the supernatant of each group and the mRNA expression of FSHβ, LHβ and GnRHR were detected.Results Compared with that of the blank group, the supernatant levels of FSH and LH in the Cetrorelix group decreased significantly \[(3.91±0.36) mIU/mL vs (2.26±0.22) mIU/mL, (8.94±0.57) mIU/mL vs (3.35±0.59) mIU/mL, P<0.05)\]. In contrast, the levels of LH significantly increased \[(8.94±0.57) mIU/mL vs (10.79±0.60) mIU/mL, P<0.05)\]; Compared with the cetrorelix group, the levels of FSH and LH in both medicated serum group and model group increased significantly (P<0.05). Compared with the blank group, the mRNA level of FSH and LH in the cetrorelix group decreased significantly \[(0.95±0.23) mIU/mL vs (0.58±0.12) mIU/mL, (0.98±0.14) mIU/mL vs (0.27±0.21) mIU/mL, P<0.01) \], and the mRNA expression of GnRHR increased in the cetrorelix group \[(0.97±0.13) mIU/mL vs (1.77±0.26) mIU/mL, P<0.01) \]; The mRNA levels of FSH and LH in the medicated serum group were increased (P<0.05). Compared with the cetrorelix group, the mRNA expression of FSHβ mRNA and LHβ were both increased in the medicated serum group and model group (P<0.05), the mRNA expression of GnRHR decreased (P<0.01).Conclusion It is suggested that the therapeutic mechanism of BuShen ZhuYun Decotion may be related to the improvement of GnRH receptor expression.
