Study on the mechanism of Danpi-Chishao in the treatment of sepsis based on network pharmacology / 中国医师杂志

Objective:To analyze the mechanism of Danpi-Chishao in treatment of sepsis based on network pharmacology.Methods:The corresponding targets of Danpi-Chishao and sepsis were carried out through TCMSP database, OMIM database and Genecards database. Cystoscope 3.8.2 software was used to construct the " Chinese medicine-active components-target-disease" network diagram. Gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analysis were carried out by DAVID database. Weisheng cloud platform was used to draw bubble map.Results:A total of 36 effective components of Danpi-Chishao was obtained, mainly including quercetin, kaempferol, baicalin, β-sitosterol, stigmasterol, paeoniflorin and so on. There were 96 potential common key targets between Danpi-Chishao and sepsis, such as prostaglandin-endoperoxide synthase 2 (PTGS2), transcription factor p65 (RELA), phosphatidylinositol-4, 5-bisphosphate 3-kinase catalytic subunit gamma (PIK3CG), B-cell lymphoma 2 (BCL-2)-associated X (BAX), BCL-2, Caspase-3 (CASP3) with a degree value>4.9. The result of protein-protein interaction (PPI) network analysis showed that there were 10 important target proteins, including alpha serine/threonine-protein kinase (AKT1), interleukin-6 (IL-6), tumor necrosis factor (TNF), interleukin-1β (IL-1β), vascular endothelial growth factor A (VEGFA), cellular tumor antigen p53 (TP53), matrix metalloproteinase-9 (MMP9), CASP3, PTGS2, C-C motif chemokine ligand 2 (CCL2). The pathways obtained by GO and KEGG enrichment analysis included atherosclerosis pathway, advanced glycation end products (AGE)-receptor for advanced glycation end products (RAGE) signal pathway, cancer pathway, tumor necrosis factor signal pathway, hypoxia-inducible factor (HIF) signal pathway, IL-17 signal pathway and other pathway.Conclusions:The mechanism of the intervention effect of Danpi-Chishao on sepsis may be that the active components such as quercetin, kaempferol, paeoniflorin act on target proteins such as PTGS2, RELA, PIK3CG, BAX, BCL2, CASP3, and through TNF-related signal pathway, HIF-1 signal pathway, IL-17 signal pathway, etc. Nonetheless, the conclusion needs further experimental verification.

Its morbidity and mortality are increasing year by year, which seriously threatens people's life and health. The diseases causing CHF are complex and varied, such as coronary heart disease, hypertension, diabetes, cardiomyopathy and so on. It is of great significance to establish animal models of CHF according to different etiologies to explore the pathogenesis of CHF and develop drugs to prevent and treat CHF induced by different diseases. Therefore, based on the classification of the etiology of CHF, this paper summarizes the animal models of CHF widely used in recent 10 years, and the application of these animal models in traditional Chinese medicine(TCM) research, in order to provide ideas and strategies for studying the pathogenesis and treatment of CHF, and provide ideas for TCM modernization research.

The traditional Chinese medicines treat chronic heart failure and their main bioactive constituents and mechanisms

Chronic heart failure (CHF) is a severe public health problem with increasing morbidity and mortality, any treatment targeting a single session is insufficient to tackle this. CHF is characterized by reduced cardiac output resulting from neurohumoral dysregulation and cardiac remodeling, which might be related to oxidative stress, inflammation, endoplasmic reticulum stress, apoptosis, autophagy, mitochondrial function, and angiogenesis. These molecular mechanisms interact with each other through crosstalk. Historically, Chinese medicinal herbs have been widely applied in the treatment of CHF, and therapeutic effects of Chinese medicinal herbs and their ingredients have been scientifically confirmed over the past decades. Traditional Chinese medicine (TCM) with multiple components can confront the different pathogenesis of CHF through multiple targets. This review analyzes commonly used TCM patent drugs and TCM decoctions that are applicable to different stages of CHF based on clinical trials. Diverse bioactive ingredients in Chinese medicinal herbs have been found to treat CHF via multiple molecular mechanisms. This review comprehensively covers the key works on the effects and underlying mechanisms of TCM, herbal ingredients and synergistic effects of constituent compatibility in treating CHF, providing additional ideas to address this threat.

Switching from efavirenz to elvitegravir/cobicistat/emtricitabine/tenofovir alafenamide reduces central nervous system symptoms in people living with HIV / 中华医学杂志(英文版)

BACKGROUND@#Central nervous system (CNS) symptoms after efavirenz (EFV) treatment in people living with human immunodeficiency virus (HIV) could persist and impact their quality of life. We assessed the impact of EFV-based regimen replacement with elvitegravir/cobicistat/emtricitabine/tenofovir alafenamide (E/C/F/TAF), which is considered an alternative option for subjects who do not tolerate EFV. Most specifically, we assessed the safety and the efficacy of E/C/F/TAF and its effects on the participants' neuropsychiatric toxicity symptoms in a real-life setting.@*METHODS@#A prospective cohort study was conducted among virologic suppressed HIV-positive participants receiving EFV-based regimens with ongoing CNS toxicity ≥ grade 2. The participants were switched to single-pill combination regimens E/C/F/TAF and followed up for 48 weeks. The neuropsychiatric toxicity symptoms were measured using a CNS side effects questionnaire, as well as the Hospital Anxiety and Depression Scale and the Pittsburgh Sleep Quality Index. The primary outcome measure was the proportion of participants experiencing grade 2 or higher CNS toxicity after EFV switch off at weeks 12, 24, and 48. Secondary endpoints included virologic and immunological responses and the effect on fasting lipids at week 48 after switch.@*RESULTS@#One hundred ninety-six participants (96.9% men, median age: 37.5 years, median: 3.7 years on prior EFV-containing regimens) were included in the study. Significant improvements in anxiety and sleep disturbance symptoms were observed at 12, 24, and 48 weeks after switching to E/C/F/TAF (P < 0.05). No significant change in depression symptom scores was observed. At 48 weeks after switch, HIV viral load <50 copies/mL was maintained in all of the participants, median fasting lipid levels were moderately increased (total cholesterol [TC]: 8.2 mg/dL, low-density lipoprotein cholesterol [LDL-C]: 8.5 mg/dL, high-density lipoprotein cholesterol [HDL-C]: 2.9 mg/dL, and triglyceride (TG): 1.6 mg/dL, and the TC:HDL-C ratio remained stable.@*CONCLUSIONS@#The single-pill combination regimens E/C/F/TAF is safe and well tolerated. This study reveals that switching from EFV to E/C/F/TAF significantly reduces neuropsychiatric toxicity symptoms in people living with HIV with grade 2 or higher CNS complaints.

Research progress of natural non-alkaloids with analgesic activity / 中国中药杂志

Pain is a complex, unpleasant feeling and emotional experience associated with actual or potential tissue damage, and manifests itself in certain autonomous psychological and behavioral responses. The commonly used opioid and non-steroidal anti-inflammatory analgesics(NSAIDs) may cause adverse reactions to the kidney, liver, cardiovascular or gastrointestinal system and cause problems of drug abuse. Therefore, it is necessary to study new analgesic drugs with less side effects and significant analgesic effects. A variety of natural products derived from terrestrial plants, microorganisms, marine organisms and fungi have been an important source of clinical medicines and provide an inexhaustible resource for the development and innovation of modern medicines. Therefore, this paper mainly reviews the natural non-alkaloids with analgesic activity in order to provide reference for the research and development of analgesic drugs derived from natural products.

Research progress of natural alkaloids with analgesic activity / 中国中药杂志

Pain is a protective defense response of the body to harmful stimuli. Long-term pain not only seriously affects the body of the patient and brings great pain to the patient, but also brings huge economic burden to the patient's family and society. It has become one of the most serious problems affecting human health. At present, opioids and non-steroidal anti-inflammatory drugs(NSAIDs) are commonly used as painkillers, but they tend to cause a variety of adverse reactions or risk of addiction. To find and develop new analgesic drugs, which are safer and more effective, has become the hot spot and difficulty in medical research. A variety of alkaloids derived from terrestrial plants, microorganisms, marine organisms and fungi have been an important source of clinical analgesic medicines. Various alkaloids have been proved to have good analgesic effects, such as morphine and the related to opioids, the main analgesic active components from Corydalis Rhizoma and Aconiti Lateralis Radix Praeparata. Here we summarized the research progress of natural alkaloids with analgesic activity, in order to provide reference for the research and development of analgesic drugs based on natural products.

Safety and efficacy of allogeneic natural killer cell immunotherapy on human immunodeficiency virus type 1 immunological non-responders: a brief report / 中华医学杂志(英文版)

BACKGROUND@#Allogeneic natural killer (NK) cell immunotherapy is recognized as a promising anti-tumor strategy, but whether it plays a role in poor CD4 recovery among human immunodeficiency virus type 1 (HIV-1) infected patients is unknown. This study aimed to investigate the safety and effectiveness of allogeneic NK cells immunotherapy on HIV-1 immunological non-responders (INRs) receiving antiretroviral therapy (ART).@*METHODS@#From February to April 2018, a prospective, randomized, controlled, open-label clinical trial, which enrolled 20 HIV-1 INRs following specific inclusion criteria, was conducted at Nankai University Second People's Hospital. Participants were randomly allocated (simple randomization 1:1) to either the combined treatment (NK + ART) group (n = 10) or the control (ART) group (n = 10). The allogenic highly activated NK cells from killer cell immunoglobulin-like receptor (KIR)/human leukocyte antigen (HLA)-Cw mismatched healthy donor were prepared (10 cells in each injection) and intravenously infused to each recruited patient of NK+ART group in three courses. Key immune parameters (CD4 count, CD8 count, CD4/CD8 ratio), laboratory tests (count of blood cells, biochemistry panel) and symptoms at baseline and at month 1, 3, 6, 9, 12, and 24 were measured/collected to analyze the safety and efficacy of the therapy. Comparisons were between the seven time-points of both groups using repeated measurement analysis of variance (ANOVA) test. Generalized estimating equations (GEE) model was performed to evaluate the overall effect of the NK+ART group vs. the ART group.@*RESULTS@#From baseline to 24 months, we noted a mean CD4 count augmentation (139 to 243 cells/μL) in the NK + ART group and (144 to 176 cells/μL) in the ART group (difference, 67; 95% CI, 10 to 124; P = 0.024). Our estimations revealed that NK+ART group could improve CD4 level (β = 54.59, P = 0.006) and CD8 level (β = 322.47, P = 0.010) on average among the six measurements compared with the ART group. Only two (2/10, 20%) participants in the NK+ART group developed a transient mild fever after the first course.@*CONCLUSIONS@#This preliminary study informs that HIV-1 INRs, allogenic NK cells immunotherapy is safe and could significantly improve CD4 recovery but not CD4/CD8 ratio. The practical effects, however, need long-term follow-up observations. Further study on the potential underlying mechanism is warranted.

Increased early activation of CD56dimCD16dim/- natural killer cells in immunological non-responders correlates with CD4+ T-cell recovery / 中华医学杂志(英文版)

BACKGROUND@#Natural killer (NK) cells play a critical role in suppressing human immunodeficiency virus-1 (HIV-1) infection, but knowledge on whether and how NK cells affect immune reconstitution in HIV-1-infected individuals who receive antiretroviral therapy (ART) is limited.@*METHODS@#We performed a case-control study with 35 healthy individuals and 66 HIV-1-infected patients including 32 immunological non-responders (INRs) with poor CD4+ T-cell recovery (500 cells/μL after 4 years of ART). NK cell phenotype, receptor repertoire, and early activation in INRs and IRs were investigated by flow cytometry.@*RESULTS@#A significantly higher proportion of CD56dimCD16dim/- NK cells was observed in INRs than IRs before ART and after 4 years of ART. The number of CD56dimCD16dim/- NK cells was inversely correlated with CD4+ T-cell counts in INRs before ART (r = -0.344, P = 0.050). The more CD69-expressing NK cells there were, the lower the CD4+ T-cell counts and ΔCD4, and these correlations were observed in INRs after ART (r = -0.416, P = 0.019; r = -0.509, P = 0.003, respectively). Additionally, CD69-expressing CD56dimCD16dim/- NK cells were more abundant in INRs than those in IRs (P  = 0.018) after ART, both of which had an inverse association trend towards significance with CD4+ T-cell counts. The expression of the activating receptors NKG2C, NKG2D, and NKp46 on CD56dimCD16dim/- NK cell subsets were higher in IRs than that in INRs after 4 years of ART (all P < 0.01). Strong inverse correlations were observed between CD69 expression and NKG2C, NKG2A-NKG2C+, NKG2D, and NKp46 expression on CD56dimCD16dim/- NK cells in INRs after ART (NKG2C: r = -0.491, P = 0.004; NKG2A-NKG2C+: r = -0.434, P = 0.013; NKG2D: r = -0.405, P = 0.021; NKp46: r = -0.457, P = 0.008, respectively).@*CONCLUSIONS@#INRs had a larger number of CD56dimCD16dim/- NK cells characterized by higher activation levels than did IRs after ART. The increase in the CD56dimCD16dim/- NK cell subset may play an adverse role in immune reconstitution. Further functional studies of CD56dimCD16dim/- NK cells in INRs are urgently needed to inform targeted interventions to optimize immune recovery.

Mechanism of β-carboline alkaloids inhibiting migration and invasion of SGC-7901 cells / 中国中药杂志

To explore the mechanism of β-carboline alkaloids inhibiting the migration and invasion of SGC-7901 cells and its correlation with FAK gene expression,CCK-8 method was used to determine the inhibitory rate of β-carboline alkaloids on the proliferation of gastric cancer SGC-7901 cells under different concentrations.The effect of β-carboline alkaloids on the migration and invasion of SGC-7901 cells was used by Transwell compartment.Detection of mRNA and protein expression of FAK genes were used by qRT-PCR and Western blot.Then si-FAK-1051 recombinant plasmid was transfected into SGC-7901 cells.FAK gene silencing effect was identified by qRT-PCR and Western blot technique again.Finally,the effects of FAK gene silencing on proliferation and migration of gastric cancer SGC-7901 cells were detected by CCK-8 kit and Transwell chamber assay respectively.With the increase of the concentration ofβ-carboline alkaloids,the inhibitory rate of SGC-7901 cells in human gastric cancer cells increased gradually,with IC5013.364 mg·L-1.The number of SGC-7901 cells of Transwell compartment in the positive experimental group(5-FU,5 mg·L-1) and the β-carboline alkaloids group decreased significantly(P<0.01) and the number of SGC-7901 cells in the β-carboline alkaloids group was significantly lower than that in the positive experimental group(P<0.01).Compared with the blank control group,the mRNA and protein expression level of FAK genes in the positive experimental group was significantly lower than that in the experimental group of β-carboline alkaloids(P<0.05).After transfection of si-FAK-1051 into gastric cancer SGC-7901 cells,the expression of mRNA and protein of FAK gene was significantly down regulated(P<0.05).SGC-7901 cell proliferation and cell migration ability also decreased significantly(P<0.05).β-carboline alkaloids are more effective than 5-FU in inhibiting migration and invasion of gastric cancer SGC-7901 cells,and the mechanism may be related to the inhibition of mRNA and protein expression of FAK gene by β-carboline alkaloids.
