RESUMO

A research strategy combining transcriptome data mining and experimental verification was adopted to identify the marker genes characterizing the syndrome elements of phlegm, stasis, and deficiency in steroid-induced osteonecrosis of the femoral head(SONFH). Firstly, the common differentially expressed gene sets of SONFH with the syndromes of phlegm-stasis obstructing collaterals, vessel obstruction, and liver-kidney deficiency were obtained from the clinical transcriptomic analysis of a previous study. The differential expression trend analysis and functional gene mining were then employed to predict the candidate marker gene sets representing phlegm, stasis, and deficiency. The whole blood samples from SONFH patients, whole blood samples from SONFH rats, and affected femoral head tissue samples were collected for qPCR, which aimed to determine the expression levels of the candidate marker genes mentioned above. Furthermore, the receiver operating characteristic curve(ROC) was established to objectively evaluate the syndrome differentiation effectiveness of the candidate marker genes mentioned above. The transcriptome data analysis results showed that the candidate marker genes for phlegm was ELOVL fatty acid elongase 6(ELOVL6), and those for stasis were ankyrin 1(ANK1), glycophorin A/B(GYPA/B), and Rh-associated glycoprotein(RHAG). The candidate marker genes for deficiency were solute carrier family 2 member 1(SLC2A1) and stomatin(STOM). The qPCR results showed that compared with that in the non-SONFH group, ELOVL6 had the lowest expression level in the peripheral blood of the SONFH patients with the syndrome of phlegm-stasis obstructing collaterals(P<0.05). Compared with that in the normal control group, ELOVL6 had the lowest expression level in the peripheral blood and affected femoral head tissue of SONFH rats modeled for 4 weeks(P<0.01), and it showed better syndrome differentiation effectiveness of rats modeled for 4 weeks(AUC=0.850, P=0.006) than at other modeling time points(8, 12, 16, and 21 weeks, AUC of 0.689, 0.766, 0.588, and 0.662, respectively). Compared with that in the non-SONFH group, the expression levels of ANK1, GYPA, and RHAG were the lowest in the peripheral blood of SONFH patients with the vessel obstruction syndrome(P<0.05). The expression levels of the three genes were the lowest in the peripheral blood and affected femoral head tissue of SONFH rats modeled for 12 weeks(P<0.05, P<0.01), and their syndrome differentiation effectiveness in the rats modeled for 12 weeks(GYPA: AUC=0.861, P=0.012; ANK1: AUC=0.855, P=0.006; RHAG: AUC=0.854, P=0.009) was superior to that for 4, 8, 16, and 21 weeks(GYPA: AUC=0.646, 0.573, 0.691, and 0.617, respectively; ANK: AUC1=0.630, 0.658, 0.657, and 0.585, respectively; RHAG: AUC=0.592, 0.511, 0.515, and 0.536, respectively). Compared with the non-SONFH group, both SLC2A1 and STOM had the lowest expression levels in the peripheral blood of patients with the syndrome of liver and kidney deficiency(P<0.05). Compared with the normal control group, their expression levels were the lowest in the peripheral blood and affected femoral head tissue of SONFH rats modeled for 21 weeks(P<0.05, except STOM in the peripheral blood of rats). Moreover, the syndrome differentiation effectiveness of SLC2A1 in the rats modeled for 21 weeks(AUC=0.806, P=0.009) was superior to that for 4, 8, 12, and 16 weeks(AUC=0.520, 0.580, 0.741, 0.774, respectively), and STOM was meaningless in syndrome differentiation. In summary, the candidate marker gene for phlegm in SONFH is ELOVL6; the candidate marker genes for stasis are GYPA, RHAG, and ANK1; the candidate marker gene for deficiency is SLC2A1. The results help to reveal the biological connotations of phlegm, stasis, and deficiency in SONFH at the genetic level.

RESUMO

ETHNOPHARMACOLOGICAL RELEVANCE: Xiaoqinglong Decotion (XQLD) is a commonly used Chinese herbal formula in clinical practice, especially for allergic diseases such as asthma. However, its intrinsic mechanism for the treatment of neutrophilic asthma (NA) remains unclear. AIM OF THE STUDY: The aim of this study was to evaluate the efficacy and potential mechanisms of XQLD on NA using network pharmacology and in vivo experiments. MATERIALS AND METHODS: First, the active compounds, potential targets and mechanisms of XQLD against NA were initially elucidated by network pharmacology. Then, OVA/CFA-induced NA mice were treated with XQLD to assess its efficacy. Proteins were then analyzed and quantified using a Tandem Mass Tags approach for differentially expressed proteins (DEPs) to further reveal the mechanisms of NA treatment by XQLD. Finally, the hub genes, critical DEPs and potential pathways were validated. RESULTS: 176 active compounds and 180 targets against NA were identified in XQLD. Protein-protein interaction (PPI) network revealed CXCL10, CX3CR1, TLR7, NCF1 and FABP4 as hub genes. In vivo experiments showed that XQLD attenuated inflammatory infiltrates, airway mucus secretion and remodeling in the lungs of NA mice. Moreover, XQLD significantly alleviated airway neutrophil inflammation in NA mice by decreasing the expression of IL-8, MPO and NE. XQLD also reduced the levels of CXCL10, CX3CR1, TLR7, NCF1 and FABP4, which are closely associated with neutrophil inflammation. Proteomics analysis identified 28 overlapping DEPs in the control, NA and XQLD groups, and we found that XQLD inhibited ferroptosis signal pathway (elevated GPX4 and decreased ASCL3) as well as the expression of ARG1, MMP12 and SPP1, while activating the Rap1 signaling pathway. CONCLUSION: This study revealed that inhibition of ARG1, MMP12 and SPP1 expression as well as ferroptosis pathways, and activation of the Rap1 signaling pathway contribute to the therapeutic effect of XQLD on NA.

RESUMO

Renal fibrosis (RF) is the end stage of several chronic kidney diseases. Its series of changes include excessive accumulation of extracellular matrix, epithelial-mesenchymal transition (EMT) of renal tubular cells, fibroblast activation, immune cell infiltration, and renal cell apoptosis. RF can eventually lead to renal dysfunction or even renal failure. A large body of evidence suggests that natural products in traditional Chinese medicine (TCM) have great potential for treating RF. In this article, we first describe the recent advances in RF treatment by several natural products and clarify their mechanisms of action. They can ameliorate the RF disease phenotype, which includes apoptosis, endoplasmic reticulum stress, and EMT, by affecting relevant signaling pathways and molecular targets, thereby delaying or reversing fibrosis. We also present the roles of nanodrug delivery systems, which have been explored to address the drawback of low oral bioavailability of natural products. This may provide new ideas for using natural products for RF treatment. Finally, we provide new insights into the clinical prospects of herbal natural products.

RESUMO

BACKGROUND: Ischemic stroke, a severe and life-threatening neurodegenerative condition, currently relies on thrombolytic therapy with limited therapeutic window and potential risks of hemorrhagic transformation. Thus, there is a crucial need to explore novel therapeutic agents for ischemic stroke. Ginsenoside Rg1 (Rg1), a potential neuroprotective agent, exhibits anti-ischemic effects attributed to its anti-inflammatory, anti-oxidant, and anti-apoptotic properties. Nevertheless, the precise underlying mechanism of action remains to be fully elucidated. PURPOSE: This study aimed to explore whether Rg1 exerts anti-ischemic stroke effects by inhibiting pyroptotic neuronal cell death through modulation of the chemokine like factor 1 (CKLF1)/ C-C chemokine receptor type 5 (CCR5) axis. METHODS: In this study, the MCAO model was used as an ischemic stroke model, and experimental tests were performed after 6 hours of ischemia. The anti-ischemic effect of Rg1 was examined by TTC staining, nissl-staining and neurobehavioral tests. In the in vitro experiments, PC12 cells were subjected to stimulation with CKLF1's mimetic peptide C27 to assess the potential of CKLF1 to induce focal neuronal cell death. Additionally, the impact of CKLF1 mimetic peptide C27, antagonistic peptide C19, and CCR5 inhibitor MVC on PC12 cells subjected to oxygen-glucose deprivation (OGD) and subsequently treated with Rg1 was investigated. In vivo, Rg1 treatment was examined by quantitative real-time PCR (qPCR), ELISA, immunohistochemistry (IHC), immunofluorescence (IF), western blot (WB), and co-immunoprecipitate (Co-IP) assays to perspective whether Rg1 treatment reduces CKLF1/CCR5 axis-induced pyroptotic neuronal cell death. In addition, to further explore the biological significance of CKLF1 in ischemic stroke, CKLF1-/- rats were used as the observation subjects in this study. RESULTS: The in vitro results suggested that CKLF1 was able to induce neuronal cells to undergo pyroptosis. In vivo pharmacodynamic results showed that Rg1 treatment was able to significantly improve symptoms in ischemic stroke rats. In addition, Rg1 treatment was able to inhibit the interaction between CKLF1 and CCR5 after ischemic stroke and inhibited CKLF1/CCR5 axis-induced pyroptosis. The results of related experiments in CKLF1-/- rats showed that Rg1 lost its therapeutic effect after CKLF1 knockdown. CONCLUSION: Our findings indicate that the activation of the NLRP3 inflammasome is initiated by the CKLF1/CCR5 axis, facilitated through the activation of the NF-κB pathway, ultimately resulting in the pyroptosis of neuronal cells. Conversely, Rg1 demonstrates the capability to mitigate neuronal cell damage following CKLF1-induced effects by suppressing the expression of CKLF1. Thus, CKLF1 represents a crucial target for Rg1 in the context of cerebral ischemia treatment, and it also holds promise as a potential target for drug screening in the management of ischemic stroke.

RESUMO

Astragalus membranaceus (AM) is a traditional Chinese herbal medicine extensively utilized in vascular cognitive impairment (VCI) treatment. However, due to the complex components of AM, its exact molecular mechanism remains unclear. Therefore, this study investigated the target and molecular mechanism of AM to treat VCI based on network pharmacology and molecular docking. Firstly, the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform, STITCH, and SwissTargetPrediction were utilized to gather the primary active ingredients of AM. The potential therapeutic targets of VCI were collected through GeneCards, OMIM, and DisGeNET databases. Secondly, the protein-protein interaction network was built using the STRING database. The enrichment analysis of gene ontology and the Kyoto Encyclopedia of Genes and Genome pathways was carried out in the R language. Finally, The network topology calculation of Cytoscape software was combined with module analysis to predict the binding properties of its active ingredients and targets. Twenty effective compounds and 733 targets were screened from AM, among which 158 targets were seen as possible targets of AM to treat VCI. MAPK3 and MMP9 were the critical targets of AM intervention in VCI. The crucial pathways include PI3K/Akt, MAPK, Rap1, and Ras signaling pathways. Besides, calycosin and quercetin might be the potential active compounds of AM for VCI treatment. AM intervenes in VCI through a multi-ingredient, multi-target, and multi-pathway coordination mechanism. These findings provide a foundation for a deeper understanding of the molecular mechanisms by which AM is effective in treating VCI.

RESUMO

Metallosupramolecular hosts of nanoscopic dimensions, which are able to serve as selective receptors and catalysts, are usually composed of only one type of organic ligand, restricting diversity in terms of cavity shape and functional group decoration. We report a series of heteroleptic [Pd2 A2 B2 ] coordination cages that self-assemble from a library of shape complementary bis-monodentate ligands in a non-statistical fashion. Ligands A feature an inward pointing NH function, able to engage in hydrogen bonding and amenable to being functionalized with amide and alkyl substituents. Ligands B comprise tricyclic aromatic backbones of different shape and electronic situation. The obtained heteroleptic coordination cages were investigated for their ability to bind phosphate diesters as guests. All-atom molecular dynamics (MD) simulations in explicit solvent were conducted to understand the mechanistic relationships behind the experimentally determined guest affinities.

RESUMO

Chinese chives is a popular herb vegetable and medicine in Asian countries. Southwest China is one of the centers of origin, and the mountainous areas in this region are rich in wild germplasm. In this study, we collected four samples of germplasm from different altitudes: a land race of cultivated Chinese chives (Allium tuberosum), wide-leaf chives and extra-wide-leaf chives (Allium hookeri), and ovoid-leaf chives (Allium funckiaefolium). Leaf metabolites were detected and compared between A. tuberosum and A. hookeri. A total of 158 differentially accumulated metabolites (DAM) were identified by Gas Chromatography-Mass Spectrometry (GC-MS) and Liquid Chromatography-Mass Spectrometry (LC-MS), among which there was a wide range of garlic odor compounds, free amino acids, and sugars. A. hookeri contains a higher content of fructose, garlic odor compounds, and amino acids than A. tuberosum, which is supported by the higher expression level of biosynthetic genes revealed by transcriptome analysis. A. hookeri accumulates the same garlic odor compound precursors that A. tuberosum does (mainly methiin and alliin). We isolated full-length gene sequences of phytochelatin synthase (PCS), γ-glutamyltranspeptidases (GGT), flavin-containing monooxygenase (FMO), and alliinase (ALN). These sequences showed closer relations in phylogenetic analysis between A. hookeri and A. tuberosum (with sequence identities ranging from 86% to 90%) than with Allium cepa or Allium sativum (which had a lower sequence identity ranging from 76% to 88%). Among these assayed genes, ALN, the critical gene controlling the conversion of odorless precursors into odor compounds, was undetected in leaves, bulbs, and roots of A. tuberosum, which could account for its weaker garlic smell. Moreover, we identified a distinct FMO1 gene in extra-wide-leaf A. hookeri that is due to a CDS-deletion and frameshift mutation. These results above reveal the molecular and metabolomic basis of impressive strong odor in wild Chinese chives.

RESUMO

This study explored the phytoestrogen-like effect of Siwu Decoction(SWD) and the estrogen receptor(ER)-mediated molecular mechanism based on network pharmacology and in vivo experiment. The active components and targets of SWD were retrieved from Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform(TCMSP), and related targets of "estrogen" from GeneCards and Online Mendelian Inheritance in Man(OMIM). Cytoscape and STRING were employed to construct the protein-protein interaction(PPI) network and "chemical component-target-disease" network and core targets were identified, followed by Gene Ontology(GO) term enrichment and Kyoto Encyclopedia of Genes and Genomes(KEGG) pathway enrichment of the core targets by R software. For the in vivo experiment, the 22-day-old SD female rats were treated(ig) with SWD for 4 days. Via hematoxylin-eosin(HE) staining, the morphological changes of rat uterus were observed. Reverse transcriptase-polymerase chain reaction(RT-PCR) was performed to detect mRNA expression of ER subtypes, estrogen-related targets, and the main regulatory factors in the estrogen signaling pathway. The results indicated 74 targets of SWD exerted phytoestrogen-like effect. KEGG pathway enrichment result suggested that estrogen signaling pathway was closely related to the phytoestrogen-like effect of SWD. Rats in SWD group demonstrated significantly thickened endometrium and significantly decreased expression of ERα, ERß, and G protein-coupled estrogen receptor(GPER) mRNA in ovarian tissue. In addition, significant lowering of ERα and ERß mRNA expression and significant rise of GPER mRNA expression in uterine tissue were observed in the SWD group. The expression of mitogen-activated protein kinase(MAPK) p38, MEK1/2 and extracellular signal-regulated kinase(ERK)1/2 mRNA was significantly low while that of epidermal growth factor receptor(EGFR) mRNA was significantly high in both ovarian and uterine tissues of SWD group compared with those in the control group. In conclusion, the phytoestrogen-like effect of SWD is closely related to the estrogen signaling pathway. The result lays a basis for revealing molecular mechanism of SWD in the treatment of gynecological diseases.

RESUMO

Multi-drug resistance (MDR) is a complicated cellular defense mechanism for tumor cells to resist chemotherapy drugs, which is also the main cause of chemotherapy failure. In this study, a local injectable hydrogel delivery system was used to construct an on-demand sustained-release platform with the advantages of chemotherapy, photothermal therapy (PTT), and magnetic resonance imaging (MRI). It could achieve synergistic chemo-photothermal therapy and real-time evaluation of the therapeutic effects (via MRI) for MDR hepatocellular carcinoma (HCC). Furthermore, after a single administration, the prepared hydrogel with a theranostic nanoprobe could release the therapeutic agents on demand for up to 14 d. Firstly, doxorubicin (DOX) and gold-manganese oxide (Au-MnO) nanoparticles (NPs) were incorporated into liposome-based self-assembled micelles, then loaded into the thermosensitive hydrogel (F127) to form DOX@Au-MnO-L NPs/F127 hydrogel (DAML/H). The prepared NP complex showed a spherical morphology with a narrow size distribution. The prepared hydrogel drug delivery system had injectable properties and stable photothermal conversion. Both the DOX@Au-MnO-L NPs and DAML/H showed controlled drug release under near infrared (NIR) laser irradiation. The in vitro MRI studies indicated that the prepared DAML/H had a high relaxation rate (14.38 mM-1 s-1) and good MRI scanning sensitivity conditions. The in vitro and in vivo results suggested the synergistic chemo-photothermal therapy of DAML/H with NIR irradiation (808 nm, 1 W cm-2, 10 min) improved the antitumor efficacy for MDR HCC. The in vivo retention experiment of Au in tumors indicated that the prepared hydrogel drug delivery system (DAML/H) had a good ability to retain Au in the tumor for a long time (at least 14 d). The western blotting results revealed that DAML/H with laser treatment could effectively downregulate P-glycoprotein (P-gp), p53 and antiapoptotic protein (Bcl-2), whereas the expression level of proapoptotic protein (Bax) and caspase-3 were increased. Therefore, DAML/H could serve as a promising synergistic chemo-photothermal therapy for MDR HCC, and a single administration might achieve long-term (14 d), on-demand, sustained-release treatment of tumors.

RESUMO

BACKGROUND: Clinically, the traditional Chinese medicine compound Gujiansan has been widely used in the treatment of steroid-induced avascular necrosis of the femoral head (SANFH). The present study aimed to investigate the mechanisms underlying the therapeutic effect of Gujiansan. METHODS: A rat model of SANFH was established by the injection of dexamethasone (DEX) at a high dosage of 25 mg/kg/d. Then, Gujiansan was intragastrically administered for 2 weeks, 4 weeks, and 8 weeks, and histological examination of the femoral head was performed. The expression levels of related mRNAs and proteins were analyzed by qRT-PCR, Western blotting, and immunohistochemistry, and the levels of bone biochemical markers and cytokines were detected with ELISA kits. RESULTS: Gujiansan administration ameliorated SANFH and induced the expression of hypoxia-inducible factor-1α (HIF-1α), Bcl-2/adenovirus E1B 19 kDa interacting protein 3 (BNIP3), LC3, and Beclin-1 in the rat model in a dose- and time-dependent manner, and Gujiansan promoted osteocalcin secretion at the femoral head. In addition, Gujiansan increased the levels of bone formation- and bone resorption-specific markers (osteocalcin (OC), bone-specific alkaline phosphatase (BAP), tartrate resistant acid phosphatase-5b (TRACP-5b), N-terminal telopeptides of type I collagen (NTX-1), and C-terminal telopeptide of type I collagen (CTX-1)) and decreased the levels of proinflammatory cytokines (TNF-α, IL-6, and CRP) in a dose- and time-dependent manner. CONCLUSIONS: Gujiansan accelerates the formation of a new bone, promotes the absorption of the damaged bone, inhibits the inflammatory response, induces autophagy of the femoral head via the HIF-1α/BNIP3 pathway, and ultimately ameliorates SANFH.

RESUMO

BACKGROUND: Obesity and its comorbidities are associated with abnormal lipid metabolism and gut microbiota dysbiosis. Bupleuri Radix is a medicinal plant used in traditional Chinese medicine with the prevention and treatment of obesity-related diseases. In this study, we aim to validate the regulation of Bupleuri Radix Extract (BupE) on lipid metabolism in obese mice, and try to find out the potential active components and reveal the underlying mechanisms. METHODS: Ingredients in BupE, their circulating metabolites in mice and fecal biotransformation products were analyzed by ultra-performance liquid chromatography coupled to quadrupole time-of-flight mass spectrometry (UPLC/Q-TOF-MS). Western blotting, RT-PCR and ELISA were used for tests of objective genes and proteins. 16 s rRNA sequencing was performed to examine intestinal bacteria composition and microbes' functional changes were predicted with PICRUSt software. An absolute quantification method was set up via the construction of recombinant plasmid for the assays of intestinal flora. Specific microbial strains were cultured in anaerobic conditions and oral administrated to mice for intestinal mono-colonization. RESULTS: BupE attenuated obesity, liver steatosis, and dyslipidemia in HFD-fed mice by up-regulating the expression of FGF21 in liver and white adipose tissue (WAT) as well as the downstream proteins of FGF21 signal pathway including ß-klotho, GLUT1 and PGC-1α, etc. UPLC/Q-TOF-MS fingerprints showed no compounds from BupE or their metabolites or biotransformation products were detected in rodent serum samples. High-throughput pyrosequencing data indicated that BupE reversed obesity-induced constructional and functional alterations of intestinal flora. Two bacterial strains, Bacteroides acidifaciens (B. acidifaciens) and Ruminococcus gnavus (R. gnavus), were separated and identified from the feces of obese mice and by intestinal mono-colonization they were verified to intervene in the anti-obesity effects of BupE on mice. CONCLUSION: These data suggest that BupE protects against diet-induced obesity and counteracts metabolic syndrome features consistent with a mechanism involving the gut-liver axis that boosts hepatic FGF21 secretion and consequent down-stream proteins expression relating to lipid metabolism. And in this gut-liver axis, intestinal microbes such as B.acidifaciens and R.gnavus play an indispensable role.

RESUMO

BACKGROUND: Berberine (BBR) plays a neuroprotective role in the pathogenesis of Alzheimer's disease (AD), inhibiting amyloid-ß (Aß) production and promoting Aß clearance. Advanced glycation end products (AGEs) promote Aß aggregation and tau hyperphosphorylation. The activation of mTOR signaling occurring at the early stage of AD has a prominent impact on the Aß production. This work focused on whether BBR regulates the production and clearance of ribosylation-induced Aß pathology via inhibiting mTOR signaling. OBJECTIVE: To explore whether BBR ameliorates ribosylation-induced Aß pathology in APP/PS1 mice. METHODS: Western blot and immunofluorescence staining were used to detect the related proteins of the mammalian target of Rapamycin (mTOR) signaling pathway and autophagy, as well as the related kinases of Aß generation and clearance. Tissue sections and Immunofluorescence staining were used to observe Aß42 in APP/PS1 mice hippocampal. Morris water maze test was used to measure the spatial learning and memory of APP/PS1 mice. RESULTS: BBR improves spatial learning and memory of APP/PS1 mice. BBR limits the activation of mTOR/p70S6K signaling pathway and enhances autophagy process. BBR reduces the activity of BACE1 and γ-secretase induced by D-ribose, and enhances Aß-degrading enzymes and Neprilysin, and inhibits the expression of Aß in APP/PS1 mice. CONCLUSION: BBR ameliorates ribosylation-induced Aß pathology via inhibiting mTOR/p70S6K signaling and improves spatial learning and memory of the APP/PS1 mice.

RESUMO

BACKGROUND: Chinese herbal injections (CHIs) have been proven beneficial to patients with non-small cell lung cancer (NSCLC) in combination with chemotherapy. The network meta-analysis (NMA) was designed to update and expand on previous work to better evaluate the effectiveness and safety of different Yiqi Fuzheng (YQFZ) CHIs combined with the Vinorelbine plus cisplatin (NP) regimen versus NP alone for NSCLC. METHODS: We searched multiple electronic databases and identified randomized controlled trials (RCTs) concerning different YQFZ CHIs combined with the NP regimen for treating NSCLC up to March 1st, 2019. The outcomes are the objective response rate, performance status and adverse reactions (ADRs). Two individuals accomplished the quality assessment of this NMA based on the Cochrane risk of bias tool and the methodological section of the CONSORT statement. Random effects models were generated to estimate efficacy and safety outcomes. Odds ratios and corresponding 95% confidence intervals were calculated via Stata 14 software. Furthermore, the rankings for the efficacy and safety of different YQFZ CHIs for each outcome were determined by the surface under the cumulative ranking curve (SUCRA). RESULTS: Initially, a total of 4775 citations were retrieved through comprehensive searching, and 88 eligible articles involving 6695 participants and 8 CHIs were ultimately included. The cluster analysis results of the current evidence indicated that the NP regimen combined with Delisheng, Shenfu and Shenmai injections have a higher clinical effectiveness rate and better performance status compared with the NP regimen alone. Additionally, the NP regimen combined with Shenqifuzheng, Shengmai and Shenfu injections may be considered a favorable choice for reliving ADRs among patients with NSCLC. CONCLUSIONS: The current evidence demonstrated that the combination of Shenfu injection plus NP regimen could produce better outcomes than other YQFZ CHIs groups in terms of efficacy and safety. However, meticulously designed, strictly executed, high-quality trials are still required to further assess and confirm the results due to the inadequacy of the included RCTs.

RESUMO

The aim of this paper was to analyze the microarray data between ulcerative colitis(UC) patients and healthy people by bioinformatics technology, screen the differentially expressed genes of UC, and predict the potential Chinese medicines for UC. The GSE36807 gene expression profile was downloaded from the gene expression database(GEO) and the differentially expressed(both up-regulated and down-regulated) genes(DEGs) were analyzed by using R language software. The core genes in the DEGs were obtained by using String database, Cytoscape software and its plug-in analysis, and the gene ontology(GO) and Kyoto encyclopedia of genes and genomes(KEGG) were used to analyze the core genes. Moreover, the core genes and the medical ontology information retrieval platform(Coremine Medical) were mapped to each other to screen the traditional Chinese medicines and its active ingredients for treating UC. A total of 648 DEGs were screened, including 397 up-regulated genes and 251 down-regulated genes. Up-regulation of DEGs yielded 15 core genes including CXCL8, IL1 B, MMP9, CXCL1, CXCL10, CXCL9, CXCL2, CXCL5, TIMP1, CXCL11, STAT1,LCN2, IL1 RN, MMP1 and IDO1. Their biological processes and pathways were mainly enriched in interleukins, chemokine ligands and cytokines, chemokine-mediated signaling pathways, and were closely related to inflammatory responses, defense responses, cell chemotaxis, secretory granules, IL17 signaling pathways, Toll-like receptor signaling pathway, NOD-like receptor signaling pathway, and TNF signaling pathway. Potential Chinese medicines for the treatment of UC include Curcumae Longae Rhizoma, Coptidis Rhizoma, Scutellariae Radix, Dendrobii Caulis, Sanguisorbae Radix, Phellodendri Chinensis Cortex, Bletillae Rhizoma and Atractylodis Rhizoma. The analysis of DEGs and core genes could promote our understanding on pathogenesis of UC. This study provides potential gene targets and research ideas for the development of new drugs of Chinese medicine intervention for UC.

RESUMO

OBJECTIVE: At present, the relationship between autophagosomes and the prognosis of various cancers has become a subject of active investigation. A series of studies have demonstrated the correlation between autophagy microtubule-associated protein light chain 3 (LC-3), Beclin-1, and colorectal cancer (CRC). Since autophagy has dual regulatory roles in tumors, the results of this correlation are also uncertain. Hence, we summarized the relationship between Beclin-1, LC-3, and CRC using systematic reviews and meta-analysis to clarify their prognostic significance in it. METHODS: PubMed, EMBASE, Cochrane Library, and Web of Science databases were searched online up to April 1, 2019. The quality of the involving studies was assessed against the Newcastle-Ottawa Scale (NOS). Pooled hazard ratio (HR) and 95% confidence interval (CI) in a fixed or random effects model were used to assess the strength of correlation between Beclin-1, LC-3, and CRC. RESULTS: A total of 9 articles were collected, involving 2,297 patients. Most literatures scored more than 6 points, suggesting that the quality of our including research was acceptable. Our finding suggested that the expression of Beclin-1 was not associated with overall survival (HR = 0.68, 95% CI (0.31-1.52), P=0.351). Nonetheless, LC-3 expression exerted significant impact on OS (HR = 0.51, 95% CI (0.35-0.74), P < 0.05). Subgroup analysis exhibited that Beclin-1 expression was associated with OS at TNM stage III (HR = 0.04, 95% CI = 0.02-0.08, P < 0.05), surgical treatment (HR = 1.53, 95% CI (1.15-2.02), P=0.003), and comprehensive treatment (HR = 0.27 95% CI (0.08-0.92), P=0.036), respectively. Similarly, the results showed the increased LC-3 expression in CRC was related to OS in multivariate analyses (HR = 0.44, 95% CI (0.34-0.57), P < 0.05), stages (HR = 0.51, 95% CI (0.35-0.74), P < 0.05), and comprehensive treatment (HR = 0.44, 95% CI (0.34-0.57), P < 0.05). CONCLUSIONS: Autophagy-related proteins of LC-3 might be an important marker of CRC progression. However, since the number of the original studies was limited, more well-designed, large-scale, high-quality studies are warranted to provide more convincing and reliable information.

RESUMO

The randomized controlled trials about modified Sangbaipi Decoction in the treatment of acute exacerbation of chronic obstructive pulmonary disease( AECOPD) patients were collected from 7 databases( PubMed,CNKI,et al) from the establishment to December 5,2018. All the studies searched were strictly evaluated. Literatures were independently screened by two researchers according to the inclusion and exclusion criteria,and the methodological quality of included studies was evaluated. To systematically review the efficacy of modified Sangbaipi Decoction in treating AECOPD,the Meta-analysis and trial sequential analysis were conducted by using Stata/SE 14. 0 and TSA 0. 9. 5. 10 Beta,respectively. A total of 25 RCTs involving 1 784 patients were included. According to the results of Meta-analysis,compared with the control groups,the trial group had a higher clinical efficacy in AECOPD patients( RR =1. 18,95%CI[1. 13,1. 22],P = 0),improved pulmonary functions including forced expiratory volume in one second( FEV1,WMD =0. 44,95%CI[0. 01,0. 87],P = 0. 046),and the forced vital capacity( FVC,WMD = 0. 42,95%CI[0. 07,0. 22],P = 0),but no statistical significance in the percentage of forced expiratory volume in one second( FEV1%,P = 0. 067) and the first seconds breathing volume percentage of forced vital capacity( FEV1/FVC,P = 0. 238); it improved the arterial oxygen partial pressure( PaO2,SMD =0. 85,95%CI[0. 41,1. 30],P = 0) and decreased the arterial partial pressure of carbon dioxide( PaCO2,SMD =-0. 94,95% CI[-1. 70,-0. 18],P= 0. 016); and in terms of inflammatory markers,it improved the white blood cell count( WBC,WMD=-0. 94,95%CI[-1. 17,-0. 70],P = 0). The trial sequential analysis showed that the studies included with the improvement of clinical efficacy had passed the conventional and TSA threshold,so as to further confirm the evidence. According to the findings,in addition to conventional Western medicine treatment,modified Sangbaipi Decoction could improve the efficiency in treating acute exacerbation patients with chronic obstructive pulmonary disease,increase PaO2,and decrease PaCO2,with a high safety but no effect on pulmonary function. However,restricted by the low quality of studies included,this conclusion shall be further verified by more high-quality clinical trials.

RESUMO

BACKGROUND: Asthma is a chronic inflammatory disease characterized by recurrent attacks of breathlessness and wheezing, which often worsen at night or in the early morning and vary from person to person in severity and frequency. Chuankezhi injection (CKZ), as a new Chinese medicine, was recently found to have a good clinical effect on asthma. Whereas neither systematic nor meta-analysis of randomized controlled trials (RCTs) explain the efficacy of CKZ in treating asthma. Therefore, we provide a protocol to evaluate the efficacy and safety of CKZ for asthma. METHODS: From inception until April 2019, a systematic and comprehensive literature search will be conducted in both 4 Chinese databases and 3 English databases. RCTs will be included related to CKZ for asthma. We will assess the quality of the included trials in accordance with the risk of bias tools in Cochrane manual 5.1.0. We will use the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) method to assess the certainty of the estimated evidence. Data analysis will be performed using the STATA 15.0. RESULTS: This systematic review aims to assess the effectiveness and safety of CKZ for the treatment of asthma, in order to provide evidence for the clinical practice of Chinese medicine. This protocol will be conducted and reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocols (PRISMA-P) statement. The results of this meta-analysis will be submitted to a peer-reviewed journal once it is completed. CONCLUSION: The consequence of this study will furnish proof to evaluate if CKZ is effective in the treatment of asthma. PROSPERO REGISTRATION NUMBER: ROSPERO CRD42019134458.

RESUMO

BACKGROUND: Chinese medicine injections (CMIs) are extensively applied to the therapy of acute exacerbation of chronic obstructive pulmonary disease (AECOPD) in mainland China. Up to 13 different kinds of CMIs are reportedly often used for treating chronic obstructive pulmonary disease, yet, rarely head to head comparison of tests are used to decide the relative consequent among the distinct CMIs. Network meta-analysis (NMA) will be performed to further compare the effects of 13 different CMI, including direct and indirect comparisons of different CMI. METHODS: From now until April 2019, a systematic and comprehensive literature search will be conducted in both English and Chinese databases, including Medline, Embase, Cochrane library, Chongqing VIP information, Wanfang Database, China national knowledge infrastructure database, and Sino Med. Randomized controlled trials will be included related to CMI therapy for AECOPD. We will assess the quality of the included trials in accordance with the risk of bias tools in Cochrane manual 5.1.0. We will use the grading of recommendations assessment development, and evaluation method to assess the certainty of the estimated evidence from the NMA. STATA 14.0 will be used for data analysis. RESULTS: The purpose of this systematic evaluation and NMA was to summarize and rank the direct and indirect evidence for 8 different types of CMI. The NMA's findings will be reported in accordance with preferred reporting items for systematic reviews and meta analyses-NMA statement. Upon completion, NMA results will be submitted to a peer-reviewed journal. CONCLUSION: With NMA, this study will provide evidence for the selection of CMI for patients with AECOPD. The results will provide information to clinicians, bridge the evidence gap and identify promising CMI targets for future trials. PROSPERO REGISTRATION NUMBER: PROSPERO CRD 42019132955.

RESUMO

BACKGROUND: Chronic obstructive pulmonary disease (COPD) has the characteristics of high incidence, mortality, disability rate, and heavy economic burden. Symptomatic measures such as anti-inflammatory, antispasmodic and anti-asthmatic are widely used in the treatment of COPD, and pulmonary rehabilitation has not been fully utilized. It is reported that up to 10 different kinds of Traditional Chinese exercises (TCEs) are often used for treating stable COPD. There are many randomized controlled trials (RCTs) and systematic reviews that have evaluated the efficacy of various TCEs for COPD. However, most of these studies were designed in comparison with conventional western medicine or health education. There are rarely studies to compare different TCEs head to head. Therefore, there remains uncertainty regarding the comparative efficacy among different TCEs. Thus, we plan to conduct a systematic review and Network meta-analysis (NMA) to compare the efficacy among 5 different TCEs and rank their benefits relative to each other. It is hoped that the findings of this study will facilitate the management and application of TCEs in the treatment of COPD. METHODS: A systematic and comprehensive literature search will be performed from inception to April 2019 in both English and Chinese databases, involving Medline, Cochrane Library, Embase, China National Knowledge Infrastructure Database, Wanfang Database, China Biomedical Literature Database, and Chongqing VIP information. RCTs related to TCE in the treatment of COPD will be included. Quality of included trials will be assessed according to the risk of bias tool of Cochrane Handbook 5.1.0. The GRADE approach will be used to rate the certainty of the evidence of estimates derived from NMA. Data analysis will be conducted by using STATA 14.0. RESULTS: This systematic review and NMA aims to summarize the direct and indirect evidence for different kinds of TCEs and to rank these TCEs. The findings of this NMA will be reported according to the PRISMA-NMA statement. The results of the NMA will be submitted to a peer-reviewed journal once completed. CONCLUSION: Using NMA, this study will provide an evidence profile which will be helpful to inform the selection of TCE for treating patients with COPD. The results will inform clinicians, bridge the evidence gaps, and identify promising TCE for future trials. PROSPERO REGISTRATION NUMBER: PROSPERO CRD 42019132970.
