Abstract
Objective: To retrieve, evaluate, and summarize the best evidence for the treatment of hypoxemia in patients with COVID-19 infection using the awake prone positioning, with the aim of guiding healthcare professionals in the standardized implementation of this therapy. Methods: A systematic search was conducted in databases including UpToDate, BMJ Best Practice, JBI Evidence-Based Healthcare Center, American Association of Critical-Care Nurses, Intensive Care Society, European Respiratory Society, World Health Organization website, Cochrane Library, PubMed, China National Knowledge Infrastructure (CNKI), and Wanfang. The retrieved literature was subjected to quality assessment and evidence extraction. Results: A total of ten publications were included, consisting of one thematic evidence summary, one guideline, two systematic reviews, three randomized controlled trials, and three expert consensus statements. This summary synthesizes thirty key pieces of evidence in five categories: organizational management and training, risk assessment, preparatory operations, implementation key points, and risk control. Conclusions: Awake prone positioning is beneficial for improving hypoxemia in patients with COVID-19 and is easy to implement. Medical institutions should develop nursing management systems, operational standards, and best practices for awake prone positioning based on evidence-based evidence in order to improve the quality of care management for such patients.

Abstract
Thrombocytopenia, a prevalent hematologic challenge, correlates directly with the mortality of numerous ailments. Current therapeutic avenues for thrombocytopenia are not without limitations. Here, we identify genistin, an estrogen analogue, as a promising candidate for thrombocytopenia intervention, discovered through AI-driven compound library screening. While estrogen's involvement in diverse biological processes is recognized, its role in thrombopoiesis remains underexplored. Our findings elucidate genistin's ability to enhance megakaryocyte differentiation, thereby augmenting platelet formation and production. In vivo assessments further underscore genistin's remedial potential against radiation-induced thrombocytopenia. Mechanistically, genistin's efficacy is attributed to its direct interaction with estrogen receptor β (ERβ), with subsequent activation of both ERK1/2 and the Akt signaling pathways membrane ERβ. Collectively, our study positions genistin as a prospective therapeutic strategy for thrombocytopenia, shedding light on novel interplays between platelet production and ERβ.

Abstract
Bitespiramycin, has been shown to have a therapeutic effect against respiratory tract inflammation, including a potential effect against COVID-19. A current clinical trial in China showed that bitespiramycin was an effective treatment for severe pneumonia and intracranial infection. However, there is lack of an analytical method to elucidate the distribution of bitespiramycin. In this study, a highly sensitive, rapid and reliable UPLC-MS/MS method was developed to comprehensively characterize the bitespiramycin distribution in various bio-samples, which is significantly improved upon the published work. A rapid sample preparation method was developed by using n-butanol as the solvent to extract bitespiramycin from different bio-samples. The extract was then directly analyzed by UPLC-MS/MS coupled with an alkaline-resistant column after centrifugation which avoids the time-consuming concentration process under nitrogen and redissolution. The method was employed to accurately quantify bitespiramycin and its metabolites in rat plasma, tissues, and human cerebrospinal fluid. Notably, the presence of bitespiramycin and its metabolites was identified for the first time in various rat organs including brain, testis, bladder and prostate as well as in human cerebrospinal fluid. This newly developed approach shows great promise for drug distribution assays including other antibiotics and can help elucidate the ADME of bitespiramycin.

Abstract
As emerging nanosystems, nanomotors have been applied in the active treatment of many diseases. In this paper, Pt@chitosan-loaded melatonin asymmetrical nanomaterials embedded with L-serine (S, kidney injury molecule 1-targeting agent) were constructed to alleviate acute kidney injury (AKI). The Janus nanocarriers arrived at the renal injury site via the bloodstream and exhibited high permeability. Because of melatonin distribution in the kidneys combined with H2O2-stimulated O2 release, the administration of the Janus nanosystem resulted in active treatment through the motion of nanomotors by asymmetrical O2 release.

Abstract
ING5 belongs to the inhibitor of growth (ING) candidate tumor suppressor family, which is involved in multiple cellular functions, such as cell cycle regulation, apoptosis, and chromatin remodelling. Previously, we reported that ING5 overexpression inhibits EMT by regulating EMT-related molecules, including Snail1, at the mRNA and protein levels. However, the mechanisms remain unclear. In the current study, we identify that ING5 overexpression induces the upregulation of miR-34c-5p. The expression levels of both ING5 and miR-34c-5p in NSCLC tissues from the TCGA database are decreased compared with that in adjacent tissues. Higher expression levels of both ING5 and miR-34c-5p predict longer overall survival (OS). Snail1 is the target gene of miR-34c-5p, as predicted by an online database, which is further verified by a dual-luciferase reporter assay. The expression level of Snail1 in NSCLC cells is markedly reduced following miR-34c-5p overexpression, leading to the inactivation of the Snail1 downstream TGF-β/Smad3 signaling pathway. The TGF-β signaling-specific inhibitor LY2157299 reverses the enhanced EMT, proliferation, migration, and invasion abilities induced by the miR-34c-5p inhibitor. Furthermore, tail vein injection of miR-34c-5p agomir inhibits xenografted tumor metastasis. Overall, this study concludes that miR-34c-5p, induced by ING5 overexpression, is a tumor suppressor that targets Snail1 and mediates the inhibitory effects of ING5 on the EMT and invasion of NSCLC cells. These results provide a novel mechanism mediating the antitumor effects of ING5.

Abstract
Effective drugs that can be quickly delivered to and retained for a long time in the renal tubule are necessary for acute kidney injury (AKI) treatment. In this study, a gold nanoparticle-modified mesoporous silica (Au@MSN-NH2)-camouflaged (methoxyphenyl)(morpholino)phosphinodithioic acid (GYY4137) asymmetrical nanosystem decorated with L-serine (S; an AKI-targeting agent) and D-Arg-dimethylTyr-Lys-Phe-NH2 (TK-SS31; a reactive oxygen species (ROS)-sensitive thioketal linker/mitochondria-targeted antioxidant) was constructed for the treatment of renal tubule and mitochondrial injury as well as the synergistic and active treatment of AKI. Due to the enhanced permeability and retention (EPR) of nanomotors, they could progressively accumulate in renal sites. The asymmetrical nanosystem achieved effective drug distribution in the kidney as well as pH-responsive hydrogen sulfide (H2S) release and ROS-responsive SS31 release, resulting in an active therapeutic effect mediated by nanomotor motion resulting from asymmetrical H2S release.

Abstract
Myocardial ischemia-reperfusion injury (MI/RI) seriously restricts the therapeutic effect of reperfusion. It is demonstrated that ferroptosis and apoptosis of cardiomyocytes are widely involved in MI/RI. Therefore, simultaneous inhibition of ferroptosis and apoptosis of cardiomyocytes can be a promising strategy to treat MI/RI. Besides, transferrin receptor 1 (TfR1) is highly expressed in ischemic myocardium, and apoferritin (ApoFn) is a ligand of the transferrin receptor. In this study, CsA@ApoFn was prepared by wrapping cyclosporin A (CsA) with ApoFn and actively accumulated in ischemic cardiomyocytes through TfR1 mediated endoctosis in MI/RI mice. After entering cardiomyocytes, ApoFn in CsA@ApoFn inhibited ferroptosis of ischemic cardiomyocytes by increasing the protein expression of GPX4 and reducing the content of labile iron pool and lipid peroxides. At the same time, CsA in CsA@ApoFn attenuated the apoptosis of ischemic cardiomyocytes through recovering mitochondrial membrane potential and reducing the level of reactive oxygen species, which played a synergistic role with ApoFn in the treatment of MI/RI. In conclusion, CsA@ApoFn restored cardiac function of MI/RI mice by simultaneously blocking ferroptosis and apoptosis of cardiomyocytes. ApoFn itself not only served as a safe carrier to specifically deliver CsA to ischemic cardiomyocytes but also played a therapeutic role on MI/RI. CsA@ApoFn is proved as an effective drug delivery platform for the treatment of MI/RI. STATEMENT OF SIGNIFICANCE: Recent studies have shown that ferroptosis is an important mechanism of myocardial ischemia-reperfusion injury (MI/RI). Therefore, simultaneous inhibition of ferroptosis and apoptosis of cardiomyocytes can be a promising strategy to treat MI/RI. Apoferritin, as a delivery carrier, can actively target to ischemic myocardium through binding with highly expressed transferrin receptor on ischemic cardiomyocytes. At the same time, apoferritin plays a protective role on ischemic cardiomyocytes by inhibiting ferroptosis. This strategy of killing two birds with one stone significantly improves the therapeutic effect on MI/RI while does not need more pharmaceutical excipients, which has the prospect of clinical transformation.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Shenkang injection (SKI), a Chinese patent medicine injection, has been approved for the treatment of chronic kidney disease (CKD) due to its definite clinical therapeutic efficacy. However, the effect and associated underlying mechanism of Shenkang injection against cisplatin (CDDP)-induced acute kidney injury (AKI) has not yet been well elucidated. AIM OF THE STUDY This study aims to investigate the therapeutic effect and associated underlying mechanism of Shenkang injection against CDDP-induced AKI. MATERIALS AND METHODS We established a CDDP-induced AKI mouse model to evaluate renal function by biochemical markers measurement and to observe histopathological alterations by haemotoxylin and eosin (HE)-staining sections of renal. In addition, the distribution of representative components of SKI in the kidneys of mice was evaluated by liquid chromatography tandem mass spectrometry (LC-MS/MS). Furthermore, the degree of oxidative stress and inflammation were assessed by detecting the levels of inflammatory cytokines and oxidants, while the related mechanisms were elucidated by network pharmacology. RESULTS CDDP could induce excessive inflammation and severe injury to the kidneys of mice. However, SKI significantly ameliorated the kidney damages and improved the renal function by reducing the levels of renal function markers (SCr, BUN and urine protein), and inhibiting the production of inflammatory cytokines IL-34, IL-6 and TNF-α. SKI repaired oxidative balance through up-regulation of antioxidants SOD and GSH and down-regulated oxidants MDA. Moreover, 4 components from SKI were detected in the kidney by LC-MS/MS quantification. In addition, pharmacology network indicated the PI3K/AKT, TNF, MAPK, and p53 were the possible signaling pathways for the therapeutic effect of SKI against CDDP-induced AKI, which were related to inflammation, oxidative stress and apoptosis. CONCLUSION In the present study, we for the first time demonstrated that SKI alleviates CDDP-induced nephrotoxicity by antioxidant and anti-inflammation via regulating PI3K/AKT, MAPK, TNF, and p53 signaling pathways. The study may provide a scientific rationale for the clinical indication of SKI.

Abstract
Platelets are the second most abundant blood component after red blood cells and can participate in a variety of physiological and pathological functions. Beyond its traditional role in hemostasis and thrombosis, it also plays an indispensable role in inflammatory diseases. However, thrombocytopenia is a common hematologic problem in the clinic, and it presents a proportional relationship with the fatality of many diseases. Therefore, the prevention and treatment of thrombocytopenia is of great importance. The expression of Toll-like receptors (TLRs) is one of the most relevant characteristics of thrombopoiesis and the platelet inflammatory function. We know that the TLR family is found on the surface or inside almost all cells, where they perform many immune functions. Of those, TLR2 and TLR4 are the main stress-inducing members and play an integral role in inflammatory diseases and platelet production and function. Therefore, the aim of this review is to present and discuss the relationship between platelets, inflammation and the TLR family and extend recent research on the influence of the TLR2 and TLR4 pathways and the regulation of platelet production and function. Reviewing the interaction between TLRs and platelets in inflammation may be a research direction or program for the treatment of thrombocytopenia-related and inflammatory-related diseases.

Abstract
Platelets, generated from precursor megakaryocytes (MKs), are central mediators of hemostasis and thrombosis. The process of thrombopoiesis is extremely complex, regulated by multiple factors, and related to many cellular events including apoptosis. However, the role of apoptosis in thrombopoiesis has been controversial for many years. Some researchers believe that apoptosis is an ally of thrombopoiesis and platelets production is apoptosis-dependent, while others have suggested that apoptosis is dispensable for thrombopoiesis, and is even inhibited during this process. In this review, we will focus on this conflict, discuss the relationship between megakaryocytopoiesis, thrombopoiesis and apoptosis. In addition, we also consider why such a vast number of studies draw opposite conclusions of the role of apoptosis in thrombopoiesis, and try to figure out the truth behind the mystery. This review provides more comprehensive insights into the relationship between megakaryocytopoiesis, thrombopoiesis, and apoptosis and finds some clues for the possible pathological mechanisms of platelet disorders caused by abnormal apoptosis.

Abstract
Thrombocytopenia is a TPO-related life-threatening disorder with very limited treatment options. Typical thrombopoietic agents targeting TPO signaling encounter a huge challenge. Thus, it is urgent to discover a novel TPO-independent mechanism involving thrombopoiesis and its potential targeted medications. Here, we developed a drug screening model by the Multi-Grained Cascade Forest (gcForest) algorithm and identified that 3,8-Di-O-methylellagic acid 2-O-glucoside (DMAG) (10, 20 and 40 μM) promoted megakaryocyte differentiation in vitro. Subsequent investigations revealed that DMAG (40 μM) activated ERK1/2, HIF-1β and NF-E2. Inhibition of ERK1/2 blocked megakaryocyte differentiation and attenuated the upregulation of HIF-1β and NF-E2 induced by DMAG. Megakaryocyte differentiation induced by DMAG was inhibited via knockdown of NF-E2. In vivo studies showed that DMAG (5 mg/kg) accelerated platelet recovery and megakaryocyte differentiation in mice with thrombocytopenia. The platelet level of DMAG-treated group recovered to almost 72% and 96% of control group at day 10 and 14. The platelet counts in the DMAG-treated group exhibited almost 1.5 and 1.3 fold higher compared with the irradiation (IR) group at day 10 and 14. Moreover, DMAG (10, 25 and 50 μM) stimulated thrombopoiesis in zebrafish. DMAG (5 mg/kg) could also increase platelet levels in c-MPL knockout (c-MPL-/-) mice. In summary, we establish a drug screening model through gcForest and demonstrate DMAG promotes megakaryocyte differentiation via the ERK/HIF1/NF-E2 pathway, which is more importantly independent of the TPO/c-MPL classic pathway. The present study may provide new insights into drug discovery for thrombopoiesis, TPO-independent regulation of thrombopoiesis and a promising avenue for thrombocytopenia treatment.

Abstract
CONTEXT S-Propargyl-cysteine (SPRC), an endogenous H2S modulator, exerts anti-inflammatory effects on cardiovascular and neurodegenerative disease, but it remains unknown whether SPRC can prevent autoimmune hepatitis. OBJECTIVE To evaluate the preventive effect of SPRC on concanavalin A (Con A)-induced liver injury and uncover the underlying mechanisms. MATERIALS AND METHODS Mice were randomly divided into five groups: control, Con A, SPRC (5 and 10 mg/kg injected intravenously once a day for 7 days), and propargylglycine (PAG; 50 mg/kg injected intraperitoneally 0.5 h before SPRC for 7 days). All mice except the controls were intravenously injected with Con A (20 mg/kg) on day 7. Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) levels were evaluated using kits. Inflammatory cytokines (TNF-α and IFN-γ) in the blood and in the liver were detected by ELISA Kit and real-time PCR, respectively. The expression of mitogen-activated protein kinase (MAPK) pathway proteins (p-JNK and p-Akt) and apoptosis proteins (Bax and Bcl-2) was detected using western blotting. RESULTS SPRC reduced the levels of AST (p < 0.05) and ALT (p < 0.01) and decreased the release of the inflammatory cytokines. Mechanistically, SPRC increased H2S level (p < 0.05) and promoted cystathionine γ-lyase (CSE) expression (p < 0.05). SPRC inhibited the MAPK pathway activation and the apoptosis pathway. All the effects of SPRC were blocked by the CSE inhibitor PAG. CONCLUSIONS SPRC prevents Con A-induced liver injury in mice by promoting CSE expression and producing endogenous H2S. The mechanisms include reducing the release of inflammatory cytokines, attenuating MAPK pathway activation, and alleviating apoptosis.

Abstract
BACKGROUND Cibotii rhizoma (CR) is a famous traditional Chinese medicine (TCM) used to treat bleeding, rheumatism, lumbago, etc. However, its therapeutic effects and mechanism against thrombocytopenia are still unknown so far. In the study, we investigated the effects of aqueous extracts of Cibotii rhizoma (AECRs) against thrombocytopenia and its molecular mechanism. METHODS Giemsa staining, phalloidin staining, and flow cytometry were performed to measure the effect of AECRs on the megakaryocyte differentiation in K562 and Meg-01 cells. A radiation-induced thrombocytopenia mouse model was constructed to assess the therapeutic actions of AECRs on thrombocytopenia. Network pharmacology and experimental verification were carried out to clarify its mechanism against thrombocytopenia. RESULTS AECRs promoted megakaryocyte differentiation in K562 and Meg-01 cells and accelerated platelet recovery and megakaryopoiesis with no systemic toxicity in radiation-induced thrombocytopenia mice. The PI3K/AKT, MEK/ERK, and JAK2/STAT3 signaling pathways contributed to AECR-induced megakaryocyte differentiation. The suppression of the above signaling pathways by their inhibitors blocked AERC-induced megakaryocyte differentiation. CONCLUSIONS AECRs can promote megakaryopoiesis and thrombopoiesis through activating PI3K/AKT, MEK/ERK, and JAK2/STAT3 signaling pathways, which has the potential to treat radiation-induced thrombocytopenia in the clinic.

Abstract
Rubia cordifolia (family: Rubiaceae) L (R. cordifolia) is a perennial botanical drug climbing vine. As the main part of the traditional Chinese medicine, the rhizome has a long history. A great number of literary studies have reported that it can be used for the improvement of blood circulation, hemostasis, activation of collaterals, etc. When it comes to the wide application of R. cordifolia in traditional medicine, we systematically review its traditional uses, phytochemistry and pharmacological effects. Literatures were systematically searched using several scientific databases, including China National Knowledge Infrastructure (CNKI), Baidu Scholar, PubMed, Web of Science, and other professional websites. Kew Botanical Garden and the iPlant were used for obtaining the scientific names and plant images of R. cordifolia. In addition, other information was also gathered from books including traditional Chinese herbal medicine, the Chinese Pharmacopoeia, and Chinese Materia Medica. So far, many prescriptions containing R. cordifolia have been widely used in the clinical treatment of abnormal uterine bleeding, primary dysmenorrhea and other gynecological diseases, allergic purpura, renal hemorrhage and other diseases. The phytochemistry studies have reported that more than 100 compounds are found in R. cordifolia, such as bicyclic peptides, terpenes, polysaccharides, trace elements, flavonoids, and quinones. Among them, quinones and peptides are the types of components with the highest contents in R. cordifolia. The modern pharmacological studies have revealed that R. cordifolia and its derived components have anti-tumor, anti-oxidative, anti-platelet aggregation, and anti-inflammatory effects. However, most studies are preclinical. The pharmacological mechanism of R. cordifolia has not been thoroughly studied. In addition, there are few pharmacokinetic and toxicity studies of R. cordifolia, therefore the clinical safety data for R. cordifolia is lacking. To sum up, this review for the first time summarizes a systemic and integrated traditional uses, chemical compositions, pharmacological actions and clinical applications of R. cordifolia, which provides the novel and full-scale insight for the drug development, medicinal value, and application of R. cordifolia in the future.

Abstract
Olsalazine is a typical 5-aminosalicylic acid (5-ASA) drug that depends on gut microbiota to liberate its anti-inflammatory moiety 5-ASA in the treatment of ulcerative colitis (UC). In recent decades, 5-ASA drugs combined with probiotics have achieved a better effective treatment for UC. Mechanisms of combination therapy have been widely discussed from a pharmacodynamic perspective. However, it is still unclear whether the better therapeutic efficacy of combination therapy was made by changing the metabolism of 5-ASA drugs in the colon under the regulation of probiotics. In the present study, combined with pharmacokinetic and gut microbiota analyses, we systematically evaluated the potential effect of Lactobacillus acidophilus (L. acidophilus) on the metabolism of Olsalazine at three levels (pharmacokinetic characteristics, metabolic microbiota, and metabolic enzymes) to offer some insights into this issue. As pharmacokinetic results showed, L. acidophilus barely had an influence on the pharmacokinetic parameters of Olsalazine, 5-ASA, and N-Ac-5-ASA. Notably, the colonic exposure of 5-ASA was not affected by L. acidophilus. Gut microbiota results also illustrated that L. acidophilus did not change the total abundance of azoreductase (azoR) and N-acetyltransferase (NAT) associated gut microbiota and enzymes, which are involved in the metabolism of Olsalazine. Both pharmacokinetic and gut microbiota results revealed that L. acidophilus did not increase the colonic exposure of 5-ASA to improve the efficacy of combination therapy. L. acidophilus played its role in UC treatment by regulating gut microbiota composition and amino acid, phenolic acid, oligosaccharide, and peptidoglycan metabolic pathways. There was no potential medication risk of combination therapy of Olsalazine and L. acidophilus. In summary, this research provided strong evidence of medication safety and a comprehensive understanding of therapeutic advantages for combination therapy of probiotics and 5-ASA drugs from the pharmacokinetic and gut microbiota perspectives.

Abstract
Background At present, patients with myocardial infarction remain an increased risk for myocardial ischemia/reperfusion injury (MI/RI). There lacks effectively method to treat MI/RI in clinic. For the treatment of MI/RI, it is still a bottleneck to effectively deliver drug to ischemic myocardium. In this paper, a regulatory T cells (Tregs) biomimetic nanoparticle (CsA@PPTK) was prepared by camouflaging nanoparticle with platelet membrane. Results CsA@PPTK actively accumulated in ischemic myocardium of MI/RI mice. CsA@PPTK significantly scavenged reactive oxygen species (ROS) and increased the generation of Tregs and the ratio of M2 type macrophage to M1 type macrophage in ischemic myocardium. Moreover, CsA@PPTK significantly attenuated apoptosis of cardiomyocytes and reduced the infarct size and fibrosis area in ischemic myocardium. CsA@PPTK markedly decreased the protein expression of MMP-9 and increased the protein expression of CX43 in ischemic myocardium tissue. Subsequently, the remodeling of the left ventricle was significant alleviated, and heart function of MI/RI mice was markedly improved. Conclusion CsA@PPTK showed significant therapeutic effect on MI/RI, and it has great potential application in the treatment of MI/RI. Graphical Abstract ![]()

Abstract
BACKGROUND Ischemic stroke is one of the main causes of death and disability in the world. The treatment for ischemic stroke is to restore blood perfusion as soon as possible. However, when ischemic brain tissue is re-perfused by blood, the mitochondrial permeability transition pore (mPTP) in neuron and microglia is excessively opened, resulting in the apoptosis of neuron and nerve inflammation. This aggravates nerve injury. Cyclosporine A (CsA) inhibits the over-opening of mPTP, subsequently reducing the release of ROS and the apoptosis of cerebral ischemia/reperfusion injured neuron and microglia. However, CsA is insoluble in water and present in high concentrations in lymphatic tissue. Herein, cerebral infarction tissue targeted nanoparticle (CsA@HFn) was developed to treat cerebral ischemia/reperfusion injury. RESULTS CsA@HFn efficiently penetrated the blood-brain barrier (BBB) and selectively accumulated in ischemic area, inhibiting the opening of mPTP and ROS production in neuron. This subsequently reduced the apoptosis of neuron and the damage of BBB. Consequently, CsA@HFn significantly reduced the infarct area. Moreover, CsA@HFn inhibited the recruitment of astrocytes and microglia in ischemic region and polarized microglia into M2 type microglia, which subsequently alleviated the nerve inflammation. CONCLUSIONS CsA@HFn showed a significant therapeutic effect on cerebral ischemia/reperfusion injury by alleviating the apoptosis of neuron, nerve inflammation and the damage of BBB in ischemic area. CsA@HFn has great potential in the treatment of ischemic stroke.

Abstract
Background Clinical studies have shown that the efficacy of programmed cell death receptor-1/programmed cell death ligand-1 (PD-1/PD-L1) inhibitors on glioblastoma (GBM) is much lower than what is expected because of the low immunogenicity of GBM. Ferroptosis of cancer cells can induce the maturation of dendritic cells (DC cells) and increase the activity of T cell. The activated T cells release IFN-γ, which subsequently induces the ferroptosis of cancer cells. Thus, the aim of this paper is to set up a new GBM-targeted drug delivery system (Fe3O4-siPD-L1@M-BV2) to boost ferroptosis for immunotherapy of drug-resistant GBM. Results Fe3O4-siPD-L1@M-BV2 significantly increased the accumulation of siPD-L1 and Fe2+ in orthotopic drug-resistant GBM tissue in mice. Fe3O4-siPD-L1@M-BV2 markedly decreased the protein expression of PD-L1 and increased the ratio between effector T cells and regulatory T cells in orthotopic drug-resistant GBM tissue. Moreover, Fe3O4-siPD-L1@M-BV2 induced ferroptosis of GBM cells and maturation of DC cell, and it also increased the ratio between M1-type microglia and M2-type microglia in orthotopic drug-resistant GBM tissue. Finally, the growth of orthotopic drug-resistant GBM in mice was significantly inhibited by Fe3O4-siPD-L1@M-BV2. Conclusion The mutual cascade amplification effect between ferroptosis and immune reactivation induced by Fe3O4-siPD-L1@M-BV2 significantly inhibited the growth of orthotopic drug-resistant GBM and prolonged the survival time of orthotopic drug-resistant GBM mice.

Abstract
A 7-amino acid peptide (7P), (Gly-Gln-Thr-Tyr-Thr-Ser-Gly) is one of the synthesized mimic polypeptides, which is the second envelope protein at hypervariable region 1 of chronic hepatitis C virus (HCV HVR1). It contributed to the anti-inflammatory reaction and inhibited lung Th9 responses in asthma through binding to CD81. In this study, we examined the effects of 7P on bronchoconstriction, acute inflammation of the airways, and lung Th2-type responses during allergic lung inflammation. Our results determined that 7P decreased bronchoconstriction and inhibited both acute inflammatory cytokines (TNFα, IL-1β, and IL-6) and Th2 cell cytokine responses (IL-5, IL-4, and IL-13) during allergic lung inflammation. 7P directly inhibited lung Th2 cell differentiation (7P: 5.1% vs. vehicle:12.2% and control 7P:12.2%) and suppressed airway inflammatory cytokine signal transduction to decrease Th2 cell response. Overall, 7P significantly decreased airway hyperresponsiveness (AHR), airway inflammation, and Th2 responses, which may serve as a novel therapeutic candidate during allergic lung inflammation.

Abstract
BACKGROUND Colon cancer is a most common malignant cancer in digestive system, and it is prone to develop resistance to the commonly used chemotherapy drugs, leading to local recurrence and metastasis. Paris saponin VII (PSVII) could not only inhibit the proliferation of colon cancer cells but also effectively induce apoptosis of drug-resistant colon cancer cells and reduce the metastasis of drug-resistant colon cancer cells as well. However, PSVII was insoluble in water and fat. It displayed no selective distribution in body and could cause severe hemolysis. Herein, colon cancer targeting calcium phosphate nanoparticles were developed to carry PSVII to treat drug-resistant colon cancer. RESULTS PSVII carboxymethyl-β-cyclodextrin inclusion compound was successfully encapsulated in colon cancer targeting calcium phosphate nanoparticles (PSVII@MCP-CaP) by using modified citrus pectin as stabilizer agent and colon cancer cell targeting moiety. PSVII@MCP-CaP significantly reduced the hemolysis of PSVII. Moreover, by specific accumulating in orthotopic drug-resistant colon cancer tissue, PSVII@MCP-CaP markedly inhibited the growth of orthotopic drug-resistant colon cancer in nude mice. PSVII@MCP-CaP promoted the apoptosis of drug-resistant colon cancer cells through mitochondria-mediated apoptosis pathway. Moreover, PSVII@MCP-CaP significantly inhibited the invasion and migration of drug-resistant colon cancer cells by increasing E-cadherin protein expression and reducing N-cadherin and MMP-9 protein expression. CONCLUSION PSVII@MCP-CaP has great potential in the treatment of drug-resistant colon cancer. This study also explores a new method to prepare active targeting calcium phosphate nanoparticles loaded with a fat and water insoluble compound in water.

Abstract
Thrombocytopenia is closely linked with hemorrhagic diseases, for which induction of thrombopoiesis shows promise as an effective treatment. Polyphenols widely exist in plants and manifest antioxidation and antitumour activities. In this study, we investigated the thrombopoietic effect and mechanism of 3,3′,4′-trimethylellagic acid (TMEA, a polyphenol in Sanguisorba officinalis L.) using in silico prediction and experimental validation. A KEGG analysis indicated that PI3K/Akt signalling functioned as a crucial pathway. Furthermore, the virtual molecular docking results showed high-affinity binding (a docking score of 6.65) between TMEA and mTOR, suggesting that TMEA might target the mTOR protein to modulate signalling activity. After isolation of TMEA, in vitro and in vivo validation revealed that this compound could promote megakaryocyte differentiation/maturation and platelet formation. In addition, it enhanced the phosphorylation of PI3K, Akt, mTOR, and P70S6K and increased the expression of GATA-1 and NF-E2, which confirmed the mechanism prediction. In conclusion, our findings are the first to demonstrate that TMEA may provide a novel therapeutic strategy that relies on the PI3K/Akt/mTOR pathway to facilitate megakaryocyte differentiation and platelet production.

Abstract
OBJECTIVE The aim of this study was to investigate the effects of cullin 4A (CUL4A) on promoting the proliferation and inhibiting the apoptosis of cervical cancer (CC) cells by regulating the nuclear factor-kappa B (NF-κB) signaling pathway. PATIENTS AND METHODS The protein expressions of CUL4A and NF-κB in 75 CC tissues were detected through immunohistochemistry. The correlation between the expressions of the two proteins in CC tissues was analyzed via Spearman's correlation test. Meanwhile, the prognostic significance of CUL4A expression for CC patients was analyzed by Kaplan-Meier curve. CUL4A small interfering ribonucleic acid (siRNA) was transfected into CC cells (HeLa) to downregulate the expression level of CUL4A. Subsequently, the effects of CUL4A on the proliferation and apoptosis of HeLa cells were detected by methyl thiazolyl tetrazolium (MTT) assay and flow cytometry, respectively. Finally, the effect of CUL4A on the activity of the NF-κB signaling pathway was analyzed through quantitative Real Time-Polymerase Chain Reaction (qRT-PCR). RESULTS The protein expressions of CUL4A and NF-κB in CC tissues were significantly higher than those in normal tissues (p<0.01). The results of the survival curve showed that the prognosis of CC patients with highly expressed CUL4A is poor (p<0.001). Meanwhile, lowly expressed CUL4A protein significantly inhibited the proliferation and promoted the apoptosis of HeLa cells (p<0.01). QRT-PCR results indicated that the relative messenger RNA (mRNA) expression levels of downstream genes of the NF-κB signaling pathway were significantly lower in CC cells than those in the control group (p<0.001). In addition, CUL4A expression was positively correlated with NF-κB expression in CC (p<0.001). CONCLUSIONS CUL4A promotes the invasion of CC cells through the NF-κB signaling pathway.

Abstract
Currently, clinical treatment for temozolomide (TMZ)-resistant glioblastoma multiforme (GBM) is still a difficult problem. The aim of this paper is to set up a new GBM-targeted drug delivery system to treat TMZ-resistant GBM. Zoledronate (ZOL) not only induces apoptosis of TMZ-resistant GBM cells by down-regulation of farnesyl pyrophosphate synthetase (FPPS) but also increases the proportion of M1-type GBM associated macrophages (GAM). Based on chemoattractants secreted by GBM cells, a ZOL loaded nanoparticle coated with microglia cell membrane (ZOL@CNPs) was prepared to deliver ZOL to central nervous system to treat TMZ-resistant GBM. ZOL@CNPs was actively recruited to TMZ-resistant GBM region by CX3CL1/CX3CR1 and CSF-1/CSF-1R signal axis, and the release of ZOL from ZOL@CNPs was triggered by glutathione in GBM cells. ZOL@CNPs inhibited the growth of TMZ-resistant GBM through inducing apoptosis and inhibiting the migration and invasion of TMZ-resistant GBM cells. Besides, the immunosuppressive and hypoxic microenvironment, playing an important role in the growth of TMZ-resistant GBM, was significantly improved by ZOL@CNPs through increasing the proportion of M1-type GAM and blocking the expression of HIF-1α. ZOL@CNPs has a great potential application in the treatment for TMZ-resistant GBM.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Jiaolong capsule (JLC) was approved for the therapy of gastrointestinal diseases by the State Food and Drug Administration (SFDA) of China. It has a satisfactory curative effect in the treatment of patients with inflammatory bowel disease, however, the mechanism remains to be elucidated. AIM OF THE STUDY In current study, the effects and possible mechanisms of JLC on 2,4,6-trinitrobenzene sulfonic acid (TNBS)-induced colitis were investigated. MATERIALS AND METHODS Sulfasalazine and JLC were administrated orally and initialized 6 h after TNBS enema, once a day for seven consecutive days. The effect of JLC on intestinal microbial populations and LPS/TLR-4/NF-κB pathway was observed and assessed. Thirty female SD rats were distributed into six groups randomly and equally, namely, control, TNBS, TNBS + sulfasalazine (625 mg/kg), and TNBS + three different doses of JLC (25, 50, and 100 mg/kg) groups. RESULTS The effect of JLC on restoring normal structures of colorectum and repairing colonic damage were superior to that of sulfasalazine. JLC showed a positive effect in re-balancing intestinal bacteria population of colitis, and suppressed the activation of LPS/TLR-4/NF-κB pathway. CONCLUSION The results suggest that JLC demonstrated a beneficial effect on treating colitis in a rat model. The possible mechanisms may be through the regulatory effect of intestinal commensal bacteria and down-regulation of LPS/TLR-4/NF-κB pathway.

Abstract
Neuropeptide FF (NPFF) is a neuropeptide that modulates various physiological processes. The regulatory role of NPFF in the immune and inflammatory response is currently being revealed. However, the effect of NPFF at the transcriptome level in macrophages has not been fully elucidated. Here, the impact of NPFF on gene expression at the transcriptome level of RAW 264.7 cells was investigated by RNA-seq. RAW 264.7 macrophages were treated with NPFF (1 nM) for 18 h, followed by RNA-seq examination. Differentially expressed genes (DEGs) were acquired, followed by GO, KEGG, and PPI analysis. A total of eight qPCR-verified DEGs were obtained. Next, three-dimensional models of the eight hub proteins were constructed by using homology modeling with Modeller (9v23). Finally, molecular dynamics simulation (300 ns) was performed with GROMACS 2018.2 to investigate the structural characteristics of these hub proteins. NPFF had no detectable effect on the morphology of RAW264.7 cells. A total of 211 DEGs were acquired, and an enrichment study demonstrated that the immune response-related pathway was significantly inhibited by NPFF. Moreover, the molecular dynamics optimized-protein models of the hub proteins were obtained. Collectively, NPFF inhibited the expression of immune-related genes in RAW 264.7 cells at the transcriptome level, which suggested a negative relationship between NPFF and this set of immune-related genes in RAW 264.7 macrophages. Therefore, our data may provide direct evidence of the role of NPFF in peripheral or central inflammatory diseases.

LMR-101, a novel derivative of propofol, exhibits potent anticonvulsant effects and possibly interacts with a novel target on γ-aminobutyric acid type A receptors. Epilepsia 2021; 62:238-249. [PMID: 33417274 DOI: 10.1111/epi.16757] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [What about the content of this article?

Abstract
OBJECTIVE LMR-101 is a bisphenol derivative of propofol, a short-acting general anesthetic, which is also used to manage status epilepticus (SE). We evaluated the sedative and anticonvulsant effects of LMR-101 to discover its potential to manage epilepsy and SE in the clinic. METHODS Comparative studies between LMR-101 and propofol were performed in mice to elucidate an appropriate dose range for LMR-101 that produced anticonvulsant effects without significant sedation. Then, the anticonvulsive efficacy for LMR-101 was evaluated using seizure models induced by pentylenetetrazol and (+)-bicuculline. The ability of LMR-101 to inhibit SE was assessed using a rat model of SE induced by pilocarpine. Radioligand binding assay profiles for LMR-101 were performed to evaluate the potential mechanisms of action underlying its anticonvulsant properties. RESULTS In the mouse study, LMR-101 exhibited greater anticonvulsant and lesser sedative effect compared with propofol. LMR-101 completely inhibited pentylenetetrazol-induced seizures at a dose of 50 mg/kg and exhibited heavy sedation at 300 mg/kg. Propofol anesthetized all mice and only decreased the seizure rate at 25 mg/kg. LMR-101 also suppressed seizure behaviors evoked by (+)-bicuculline in mice in a dose-dependent manner. In the pilocarpine-induced SE model, LMR-101 significantly decreased the maximum seizure score and seizure duration in a dose-dependent manner. The median effective dose for LMR-101 was 14.30 mg/kg and 121.87 mg/kg to prevent and inhibit sustained SE, respectively. In binding assays, LMR-101 primarily inhibited tert-[35 S] butylbicyclophosphorothionate binding to γ-aminobutyric acid type A (GABAA ) receptors (half-maximal inhibitory concentration = 2.06 μmol·L-1 ), but it did not affect [3 H] flunitrazepam or [3 H] muscimol binding. SIGNIFICANCE It is anticipated that LMR-101 might play an essential role in the clinical management of epilepsy and SE. LMR-101 also might bind to a novel target site on the GABAA receptor that is different from existing antiepileptic drugs. Further study of the mechanisms of action of LMR-101 would be of considerable value in the search for new active drug sites on GABAA receptors.

Abstract
Alcoholic fatty liver disease (AFLD), a major public health problem, has drawn clinical and scientific attention. The study aims to investigate the effect of Ganmeijian [crude extract of malt root, phosphoesterase complex (Pho)] on AFLD, and explore the possible mechanisms. An AFLD rat model was made. 30 and 60 mg/kg Pho were administrated through intestinal fistula for 5 weeks. Compared with those in model group, AST, LDL-C and TC in 30 mg/kg Pho group and TC in 60 mg/kg Pho group decreased. The mRNA level of Fas, Gpat1 and Srebp-1c in Pho groups was significantly reduced. The level of GSH-Px was increased, mitochondrial activity was improved, and the level of MDA and ROS was reduced in Pho groups. Pho shows a beneficial effect on AFLD. The mechanisms are possibly related to Pho inhibiting the expression of fat synthesis genes, protecting the function and increasing the activity of mitochondria in hepatocytes, then reducing the accumulation of ROS and the level of oxidative stress in the liver.

Abstract
Abstract
With the increase of computer resources and the application of global variance reduction (GVR) method, it is a trend to obtain global distribution using the Monte Carlo (MC) method in deep-penetration shielding calculation. GVR technique uses biased source and weight window to decrease the MC calculation tally error for deep-penetration problems. However, excessive splitting of large weight particles out of the source region is time-consuming for problems with significant fluence rate variation. A new GVR technique, which performs space and energy splitting/roulette based on the importance of the phase space, is proposed in this paper to avoid excessive splitting of large weight particles. The improved GVR technique is applied to the H. B. Robinson Unit 2 (HBR-2) benchmark and CAP1400 dose rate distribution calculation. Numerical results show that the new GVR technique shows excellent performance for deep-penetration shielding calculation.

Abstract
The study tried to investigate whether apple polysaccharide (AP) could prevent colitis associated colorectal cancer (CACC) through the regulation of intestinal microbiota disorders. 10 % AP (w/v) was administrated to ICR mice by gavage for 15 wk. It was found that AP treatment protected against CACC in mice effectively. The level of Lactobacillus in the intestine of AOM/DSS-treated mice was significantly decreased and that of Fusobacterium increased; while AP could reverse this trend and increase the intestinal microbiota diversity. The number of T cells and macrophages in the colon tissue of mice in AOM/DSS group elevated; while AP could reduce the number of these cells significantly. AP suppressed nuclear aggregation of β-catenin, inhibited the activation of Wnt pathway in colon tissues. These data suggest that AP prevented ICR mice from CACC at least in part through regulating intestinal flora disorder and Wnt pathway.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Saponins of many herbs could inhibit the growth of colorectal cancer cells. In the study, we investigated the effects of Paris saponin Ⅶ (PSⅦ), and elucidated its mechanism in colorectal carcinoma cells and a xenograft mouse model. MATERIALS AND METHODS HT-29 and HCT-116 cells were treated with different concentrations of PSⅦ (0-100 μM). The effects of PSⅦ on HCT-116 cells were assessed using a microarray. Then, apoptotic cells were detected by flow cytometric analysis and apoptosis related protein expression was evaluated by Western blot. A xenograft model of nude mice was used to assess the effect of PSⅦ in vivo. RESULTS MTT assay showed the IC50 values of PSⅦ for growth inhibition of HT-29 and HCT-116 cells were 1.02 ± 0.05 μM and 3.50 ± 0.79 μM respectively. Edu assay demonstrated that PSⅦ effectively suppressed the growth of HT-29 and HCT-116 cells. Treatment with 0-3 μM PSⅦ not only triggered apoptosis, but also activated caspase-3 and caspase-9 of HT-29 and HCT-116 cells in a concentration dependent manner. In parallel to the alterations, Bax and Cyto-c expression increased while Bcl-2 decreased. In nude mice, PSⅦ reduced the tumor size and induced the apoptosis of tumor cells. PSVII could suppress IL-6-induced phosphorylation of STAT3 in vitro and blocked STAT3 phosphorylation in vivo. CONCLUSION Our results suggest that PSVII suppressed the activation of IL-6/STAT3 pathway, consequently suppressed the growth and proliferation and triggered the apoptosis of CRC cells. These findings indicate that PSⅦ might be an effective tumouristatic agent for the treatment of colorectal cancer.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The development of a multidrug-resistant (MDR) phenotype is a main obstacle to the successful treatment of breast cancer. Saponins of several herbs are considered as promising candidates for drug resistance treatment. We extracted Paris saponin VII (PS VII) from Trillium tschonoskii Maxim. and investigated whether it could sensitize chemoresistant breast cancer cells MCF-7/ADR to the cytotoxic effects of adriamycin. MATERIALS AND METHODS MCF-7/ADR cells were exposed to 0.5 μM PSVII plus different concentrations of adriamycin (0-100 μM). Then, MTT assay and adriamycin accumulation assay were used to assess cell proliferation and intracellular adriamycin retention. P glycoprotein levels and intracellular rhodamine 123 (Rh-123) accumulations were investigated to measure the expression and activity of P-glycoprotein. A xenograft model of nude mouse was utilized to observe the effect of PSVII in vivo. RESULTS Treatment with PSVII influenced cell viability of MCF-7/ADR cells, as well as sensitized MCF-7/ADR cells to the cytotoxic effects of adriamycin. Moreover, PSVII significantly downregulated MDR1 expression in MCF-7/ADR cells. Intravenous administration of PSVII significantly enhanced anticancer efficacy of adriamycin to MCF-7/ADR xenograft model in nude mice. CONCLUSION These findings suggested a possible application of PSVII in combination with chemotherapy and/or as neo-adjuvant therapy in the treatment of MDR breast cancer.

Abstract
AIM To evaluate the efficacy and to identify prognostic factors of polyvinyl alcohol (PVA) chemoembolisation for treating advanced hepatocellular carcinoma (HCC) with portal vein (PV) tumour thrombosis (PVTT) and arterioportal shunts. MATERIALS AND METHODS The clinical data of 145 advanced HCC patients with PVTT and arterioportal shunts were collected. The patients were divided into two groups: group A, with main PV invasion, (n=56) and group B, with PV branch invasion, (n=89). Based on arterioportal shunt types, different particle sizes of PVA were used for chemoembolisation. The overall survival (OS), time to progression (TTP), and postoperative complications were analysed retrospectively. RESULTS The median OS of all patients was 10.1 months. The median OS of group A and group B was 8.2 and 12.5 months, respectively (χ2=6.03, p=0.01). The overall 6-, 12-, and 18-month survival rates of groups A and B were 63.8%, 24.9%, and 6.3%, and 78.1%, 55.2%, and 23.7%, respectively. After embolisation, there were two cases of acute liver failure and three cases of upper gastrointestinal bleeding. Cox multivariate survival analysis revealed that main PVTT (HR [hazard ratio]=1.75, p=0.01), Child-Pugh B class (HR=1.99, p=0.003) and tumour burden ≥50% (HR=3.25, p<0.001) were independent risk factors. A dose of oxaliplatin >100 mg (HR=0.48, p<0.001) was an independent protection factor. CONCLUSION Treatment of advanced HCC with PVTT and arterioportal shunts by PVA chemoembolisation is safe and effective. The patients achieved a better prognosis with the dose of oxaliplatin >100 mg, while main PVTT, Child-Pugh B class, and tumour burden ≥50% were poor prognostic indicators.

Abstract
Background: Teneligliptin is a 3rd-generation dipeptidyl peptidase-4 (DPP-4) inhibitor. There is a limited evidence regarding the effect of teneligliptin. Therefore, this study is to assess the efficacy and safety of teneligliptin in type 2 diabetes mellitus (T2DM) patients with inadequately glycemic controlled. Methods: A search of PubMed, Medline, Embase, and The Cochrane Library during 2000.01–2018.03 was performed for randomized controlled trials of teneligliptin compared to placebo in patients with T2DM with monotherapy or add-on treatment. Results: Ten trials with 2119 patients were analyzed. Teneligliptin produced absolute reductions in glycated hemoglobin A1c (HbA1c) levels (weighted mean difference (WMD) 0.82%, 95% confidence interval (CI) [−0.91 to −0.72], p < 0.00001) compared with placebo. However, after 36–42 weeks of follow-up (open-label), HbA1c level rise higher than duration (double-blind) in teneligliptin group. Teneligliptin led to greater decrease of fasting plasma glucose (FPG) level (vs. placebo, WMD −18.32%, 95% CI [−21.05 to −15.60], p < 0.00001). Teneligliptin also significantly decreased the 2 h post-prandial plasma glucose (2 h PPG) (WMD −46.94%, 95% CI [−51.58 to −42.30], p < 0.00001) and area under the glucose plasma concentration-time curve from 0 to 2 h (AUC0−2h) for PPG (WMD −71.50%, 95% CI [−78.09 to −64.91], p < 0.00001) compared with placebo. Patients treated with teneligliptin achieved increased homeostasis model assessment of β cell function (HOMA-β) with 9.31 (WMD, 95% CI [7.78–10.85], p < 0.00001). However, there was no significant difference between teneligliptin and placebo in overall adverse effects (0.96 risk ratio (RR), 95% CI [0.87, 1.06], p = 0.06). The risks of hypoglycemia were not significantly different between teneligliptin and placebo (1.16 RR, 95% CI [0.59, 2.26], p = 0.66). Conclusions: Teneligliptin improved blood glucose levels and β-cells function with low risk of hypoglycemia in patients with T2DM. Common adverse effects of teneligliptin including hypoglycemia were identified and reviewed. Risks of cardiovascular events are less certain, and more data for long-term effects are needed.

Abstract
Lychee seed is a traditional Chinese medicine and has many beneficial effects such as modulation of blood sugar and lipids, antioxidation, antivirus and antitumor. Studies have indicated that type II diabetes mellitus (T2DM) and Alzheimer's disease (AD) share common biological mechanisms including insulin resistance, impaired glucose metabolism, β-amyloid (Aβ) formation, oxidative stress and presence of advanced glycation end products (AGEs). The present study investigated the effects of lychee seed extract (LSE) on neuroprotection, cognitive function improvement and possible underlying mechanisms in a rat model of T2DM with cognitive impairment. We analyzed the chemical profile of LSE using a UHPLC-SPD chromatogram and evaluated its effect on the improvement of spatial learning and memory of rats by a Morris water maze. The levels of glucose, insulin, Aβ, AGEs, Tau protein and acetylcholinesterase in the blood and/or hippocampus of rats were determined by blood-glucose meter, radioimmunoassay, chemical chromatometry, enzyme-linked immunosorbent assay (ELISA) and immunohistochemical analysis, respectively. Results demonstrated that LSE consists of eight major and around 20 minor ingredients, and it remarkably prevents neuronal injury and improves cognitive functions in T2DM rats. The levels of glucose, insulin, Aβ, AGEs and Tau protein were significantly increased in the blood and/or hippocampus of T2DM rats, while LSE remarkably decreased their levels compared to vehicle treatment (P<0.01). The possible mechanisms may be associated with IR improvement and decreased formations of Aβ, AGEs and Tau protein in the hippocampus of T2DM rats. LSE may be developed as the agent for the treatment of T2DM and/or AD clinically.

Abstract
Chronic intestinal inflammation enhances cell proliferation, angiogenesis, and migration, then promotes the development of colorectal cancer (CRC). Many ingredients of apples have been proven to have anti-inflammatory properties, and show benefits for colitis treatment. In our previous studies, we found modified apple polysaccharide (MAP) could prevent colitis associated colorectal carcinogenesis effectively. Herein, we further our study to observe the effect of MAP on dextran sodium sulfate (DSS)-induced colitis and to investigate the possible mechanisms. IL-22 has both pathogenic and protective effects during intestinal tissue damage. It could be neutralized by the soluble IL-22 receptor, known as the IL-22 binding protein (IL-22BP). A DSS-induced colitis mouse model, a mouse CRC cell line MCA-38 and a mouse dendritic cell line DC2.4 were treated with MAP. Western blot, ELISA, BrdU staining and a co-culture system were used to detect the expression of IL-22 and IL-22BP. MAP significantly protected ICR mice against DSS-induced colitis, and inhibited the growth of MCA-38 cells. The mechanisms may be that MAP down-regulated IL-22 level and up-regulated expression of IL-22BP. These data may provide another molecular basis for understanding how apples act to prevent colitis and suggest that MAP has a potential to treat colitis and prevent CRC.

Abstract
Clinically, blood sample analysis has been widely used for health monitoring. In hospitals, arterial and venous blood are utilized to detect various disease biomarkers. However, collection methods are invasive, painful, may result in injury and contamination, and skilled workers are required, making these methods unsuitable for use in a resource-limited setting. In contrast, capillary blood is easily collected by a minimally invasive procedure and has excellent potential for use in point-of-care (POC) health monitoring. In this review, we first discuss the differences among arterial blood, venous blood, and capillary blood in terms of the puncture sites, components, sample volume, collection methods, and application areas. Additionally, we review the most recent advances in capillary blood-based commercial products and microfluidic instruments for various applications. We also compare the accuracy of microfluidic-based testing with that of laboratory-based testing for capillary blood-based disease diagnosis at the POC. Finally, we discuss the challenges and future perspectives for developing capillary blood-based POC instruments.

Abstract
Recently, some studies suggested that UBQLN1 variant was associated with AD risk. However, the results were inconsistent. This meta-analysis aimed to determine the association between UBQLN1 variant and AD risk. We searched the electronic databases PubMed, Embase, and CNKI databases. Random-effects model was used. All statistical tests were performed using the STATA 11.0 software (StataCorp, College Station, TX, USA). UBQLN1 variant was not associated with the risk of AD (OR=1.05; 95%CI, 0.92-1.19; I2=35%). The corresponding pooled ORs were not materially altered in sensitivity analysis. The Galbraith plot was used to find the source of the heterogeneity and no study was the outlier. The shape of the funnel plot showed symmetry. Egger's test found no evidence of publication bias (P=0.8). These results suggest that the UBQ-8i polymorphism was not associated with AD risk.

Abstract
Hepatitis B virus (HBV) infection is a serious public health problem, which can be transmitted through various routes (e.g., blood donation) and cause hepatitis, liver cirrhosis and liver cancer. Hence, it is necessary to do diagnostic screening for high-risk HBV patients in these transmission routes. Nowadays, protein-based technologies have been used for HBV testing, which however involve the issues of large sample volume, antibody instability and poor specificity. Nucleic acid hybridization-based lateral flow assay (LFA) holds great potential to address these limitations due to its low-cost, rapid, and simple features, but the poor analytical sensitivity of LFA restricts its application. In this study, we developed a low-cost, simple and easy-to-use method to improve analytical sensitivity by integrating sponge shunt into LFA to decrease the fluid flow rate. The thickness, length and hydrophobicity of the sponge shunt were sequentially optimized, and achieved 10-fold signal enhancement in nucleic acid testing of HBV as compared to the unmodified LFA. The enhancement was further confirmed by using HBV clinical samples, where we achieved the detection limit of 103 copies/ml as compared to 104 copies/ml in unmodified LFA. The improved LFA holds great potential for diseases diagnostics, food safety control and environment monitoring at point-of-care.

Abstract
Sphingosine 1‐phosphate (S1P) is an important signaling sphingolipid involved in the pathogenesis of various cardio cerebral vascular diseases such as ischemic stroke. In particular, the S1P mimetic FTY720 is protective for brain against ischemic conditions. However, whether and how FTY720 can modulate vascular tone and blood pressure remains to be determined. We showed that FTY720 (1 mg/kg) enhanced the contractile response of rat thoracic aortic rings induced by high potassium and phenylephrine, respectively. This enhancement involves the activation of extracellular signal‐regulated kinase (ERK) since ERK phosphorylation was also enhanced and application of PD98059 (10 μmol/L), an inhibitor of ERK activation abrogated the aforementioned enhanced response by FTY720. In parallel, FTY720 (1 mg/kg) led to a modest elevation of blood pressure in rats, effects also being prevented by PD98059. In contrast, FTY720 decreased the high potassium‐induced contractile response in basilarartery preparations from rabbits, an effect blocked by PD98059. Together, FTY720‐induced an enhanced response of artery contractility in aorta and in arterial pressure involving ERK activation, with an attenuation in basilarartery contractility. This action property of FTY720 would be endowed with a potential of facilitating more blood flow perfusion to the brain and improving blood supply to the ischemic brain region and could be useful as an adjuvant in the treatment of ischemic stroke in the clinics.

Abstract
Nucleic acid testing (NAT) has been widely used for disease diagnosis, food safety control and environmental monitoring. At present, NAT mainly involves nucleic acid extraction, amplification and detection steps that heavily rely on large equipment and skilled workers, making the test expensive, time-consuming, and thus less suitable for point-of-care (POC) applications. With advances in paper-based microfluidic technologies, various integrated paper-based devices have recently been developed for NAT, which however require off-chip reagent storage, complex operation steps and equipment-dependent nucleic acid amplification, restricting their use for POC testing. To overcome these challenges, we demonstrate a fully disposable and integrated paper-based sample-in-answer-out device for NAT by integrating nucleic acid extraction, helicase-dependent isothermal amplification and lateral flow assay detection into one paper device. This simple device allows on-chip dried reagent storage and equipment-free nucleic acid amplification with simple operation steps, which could be performed by untrained users in remote settings. The proposed device consists of a sponge-based reservoir and a paper-based valve for nucleic acid extraction, an integrated battery, a PTC ultrathin heater, temperature control switch and on-chip dried enzyme mix storage for isothermal amplification, and a lateral flow test strip for naked-eye detection. It can sensitively detect Salmonella typhimurium, as a model target, with a detection limit of as low as 102 CFU ml-1 in wastewater and egg, and 103 CFU ml-1 in milk and juice in about an hour. This fully disposable and integrated paper-based device has great potential for future POC applications in resource-limited settings.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Yupingfeng Powder (YPF), a Chinese medical formula, is used traditionally for allergic diseases and characterized by reducing allergy relapse. In the present study, we attempted to investigate the effect of YPF on the immunity of mice and the possible mechanisms. MATERIALS AND METHODS An immunosuppressive mice model induced by Dexamethasone (Dex) was used. Blood samples, spleen and thymus were collected. Then, hematology parameters and organ weight were measured; Phenotypic analyses (CD4+/CD8+) of lymphocytes were performed using a flow cytometer; Phagocytosis of peritoneal macrophages were evaluated by particle tracers; Spleen lymphocytes were isolated, whose proliferation and apoptosis were assessed. NK cells' cytotoxicity was determined using the LDH release assay. RESULTS YPF could ameliorate weight loss and improve low thymus and spleen coefficients caused by Dex. Treatment with YPF made decreased lymphocytic activity of Dex-treated mice back to normal and inhibited Dex-induced apoptosis of lymphocytes. YPF increased the Dex caused low proportion of CD4+/CD8+, and upregulated Dex-reduced NK cells' activity. CONCLUSION The series of experiments demonstrated that YPF could exert immune regulation and enhance immunity of immunosuppressive mice through adjusting nonspecific and cellular immunity. The results would provide a basis for clinical application of YPF.

Abstract
Breast cancer is the second leading cause of cancer-related deaths in the female patients which was mainly caused by metastasis. Development of target gene therapy for breast cancer to suppress tumor progress and metastasis will improve the therapeutic options and be of great benefit to the patients. Tumor necrosis factor-alpha-induced protein 8-like 2 is a novel molecule for maintaining immune homeostasis and is involved in cancer development. In the present study, we overexpressed TIPE2 in breast cancer cells to investigate the role of TIPE2 in the development of breast cancer. Our results showed that overexpression of TIPE2 significantly inhibited the proliferation of 4T1 cells in vitro and in vivo. We constructed a non-viral targeted gene therapeutic system by using the minicircle plasmids expressing TIPE2. We found that the growth and metastasis of breast cancer was significantly inhibited by hydrodynamic gene delivery of TIPE2 plasmids in vivo. Mechanistically, TIPE2 increased T and NK cells, and decreased MDSCs. Gene delivery of TIPE2 up-regulated the production of IFN-γ and TNF-α by CD8+ T and NK cells in spleens and tumor microenvironment, and enhanced the cytotoxic activity of CD8+ T and NK cells. Taken together, TIPE2 inhibited breast cancer development and metastasis possibly via promoting CD8+ T and NK cell-mediated antitumor immune responses. Thus, the results indicate that TIPE2 may be a potential therapeutic target for breast cancer therapy.

Abstract
Lychee seed is a traditional Chinese medicine and possesses many activities, including hypoglycemia, liver protection, antioxidation, antivirus, and antitumor. However, its effect on neuroprotection is still unclear. The present study investigated the effects of lychee seed saponins (LSS) on neuroprotection and associated mechanisms. We established a rat model of Alzheimer’s disease (AD) by injecting Aβ25–35 into the lateral ventricle of rats and evaluated the effect of LSS on spatial learning and memory ability via the Morris water maze. Neuronal apoptosis was analyzed by hematoxylin and eosin stain and terminal deoxynucleotidyl transferase (Tdt)-mediated dUTP nick-end labeling analysis, and mRNA expression of caspase-3 and protein expressions of Bax and Bcl-2 by reverse transcription-polymerase chain reaction (RT-PCR) and Western blotting, respectively. The results showed that LSS remarkably improved cognitive function and alleviated neuronal injury by inhibiting apoptosis in the hippocampus of AD rats. Furthermore, the mRNA expression of caspase-3 and the protein expression of Bax were downregulated, while the protein expression of Bcl-2 and the ratio of Bcl-2/Bax were increased by LSS. We demonstrate that LSS significantly improves cognitive function and prevent neuronal injury in the AD rats via regulation of the apoptosis pathway. Therefore, LSS may be developed as a nutritional supplement and sold as a drug for AD prevention and/or treatment.

Abstract
Heat shock proteins (HSPs) constitute a large family of proteins involved in protein folding and maturation whose expression is induced by heat shock or other stressors. The major groups are classified based on their molecular weights and include HSP27, HSP40, HSP60, HSP70, HSP90, and large HSPs. HSPs play a significant role in cellular proliferation, differentiation, and carcinogenesis. In this article we comprehensively review the roles of major HSPs in cancer biology and pharmacology. HSPs are thought to play significant roles in the molecular mechanisms leading to cancer development and metastasis. HSPs may also have potential clinical uses as biomarkers for cancer diagnosis, for assessing disease progression, or as therapeutic targets for cancer therapy.
