“Buyi Ganshen”,a traditional Chinese medicine treatment,combined with dopa preparation for Parkinson’s disease therapy:a meta-analysis of randomized controlled trials

Traditional Chinese medicine Buyi Ganshen therapy combined with dopa preparation in the therapy of Parkinson’s disease could enhance the clinical safety and efficacy compared with dopa preparation along.The exact mechanism of how Buyi Ganshen works combined with dopa preparation still unknown and the enrolled articles quality was relatively inadequate,yet it could provide the reference in the clinical application and further studies.Background:To research the influence of“Buyi Ganshen”,a traditional Chinese medicine that commonly used in“Tonifying the Liver and the Kidney”,added dopa preparation for the therapy of Parkinson’s disease.Methods:This meta-analysis examined existing literature by searching 7 electronic databases(CNKI,WanFang,EMBASE,PubMed,Medline,the Cochrane Library,and the VIP database)from inception to December 2019.Randomized controlled trials evaluating the influence of“Buyi Ganshen”combined with dopa preparation for Parkinson’s disease were identified.The main results were clinical efficacy,UPDRS I(mental score),total unified Parkinson’s disease ratingscale score,UPDRS III(motor score),UPDRS II(activities of daily life),and UPDRS IV(complications of treatment).The subordinate results were the SPOCA-AUT scores,traditional Chinese medicine syndromes and other adverse reactions.The Review Manager 5.3 software was used to calculate the pooled estimate effect.The outcomes were showed as relative ratio with 95%confidence interval.The fixed or random model was elected based on the level of homogeneity among researches.The I2 was used to detected heterogeneity.The quality of the researches was also assessed.Results:The meta-analysis include 2,241 individuals from a total of 30 studies.These data suggested that the therapy of Parkinson’s disease with the combination of“Buyi Ganshen”and dopa preparation were more effective compared to dopa preparation alone.Conclusion:“Buyi Ganshen”combined with dopa preparation exists,in some degree,to enhance clinical safety and effectiveness in the cure of Parkinson’s disease,compared with dopa preparation along.As most of the studies included were with low quality,this conclusion must be considered with caution.Thus,more multi-center,high-quality,prospective randomized controlled trials with large enough sample sizes are required to further illuminate the influence of“Buyi Ganshen”combined with dopa preparation for Parkinson’s disease.

Role of ferroptosis in Parkinson’s disease and intervention mechanism of acupuncture and moxibustion

Parkinson’s disease(PD)is the second neurodegenerative disease in the world.The pathological characteristics of PD are degeneration,loss and death of dopaminergic neurons in the substantia nigra of the midbrain.At present,most scholars believe that the main pathogenesis of PD is α-synuclein aggregation,oxidative stress,mitochondrial dysfunction and neuroinflammatory reaction.More and more studies have demonstrated that ferroptosis plays an important role in the occurrence and development of PD.Ferroptosis is a new type of cell death that is significantly different from traditional apoptosis,scorching and necrosis.Its main feature is iron-dependent lipid peroxidation.Some studies have found that the efficacy of acupuncture and moxibustion in the treatment of PD may be related to the regulation of ferroptosis.Therefore,this study mainly discusses the occurrence and development mechanism of ferroptosis and its role in PD,and the possible mechanism of acupuncture and moxibustion in the treatment of PD dopaminergic neurons,so as to provide theoretical basis for acupuncture and moxibustion in the treatment of PD.

Inhalation therapy for pulmonary fibrosis:chemical medicines and herbal medicines

Pulmonary fibrosis(PF)is a chronic,progressive,and irreversible pulmonary interstitial disease with unclear pathogenesis.Currently,there are few treatment options for managing PF.Inhalation therapy,as a routine treatment for respiratory diseases,is being used to study the treatment of PF.Some herbal medicines and their active ingredients have been reported to have anti-PF effects.This review aims to provide an overview of the latest developments in inhalation therapy,focusing on the utilization of chemical medicines and herbal medicines for the treatment of PF in both clinical practice and basic research.The inhalation of chemical drugs such as pirfenidone,nintedanib,N-acetylcysteine,and interferon-γhas been shown to demonstrate anti-PF effects.Additionally,the inhalation of various natural products derived from herbal medicines,encompassing polyphenols,alkaloids,flavonoids,saponins,terpenoids,and herbal extracts,contributes to the therapeutic management of PF through diverse mechanisms.The inhalation of both chemical and herbal medicines presents promising advantages in the treatment of PF.Further clinical trials are required to investigate the effectiveness,safety,and mechanism of action of inhalation therapy utilizing natural products derived from herbal medicines.

Highly sensitive electrochemical determination of rutin based on the synergistic effect of 3D porous carbon and cobalt tungstate nanosheets

Rutin,a flavonoid found in fruits and vegetables,is a potential anticancer compound with strong anticancer activity.Therefore,electrochemical sensor was developed for the detection of rutin.In this study,CoWO_(4) nanosheets were synthesized via a hydrothermal method,and porous carbon(PC)was prepared via high-temperature pyrolysis.Successful preparation of the materials was confirmed,and characterization was performed by transmission electron microscopy,scanning electron microscopy,and X-ray photoelectron spectroscopy.A mixture of PC and CoWO_(4) nanosheets was used as an electrode modifier to fabricate the electrochemical sensor for the electrochemical determination of rutin.The 3D CoWO_(4) nanosheets exhibited high electrocatalytic activity and good stability.PC has a high surface-to-volume ratio and superior conductivity.Moreover,the hydrophobicity of PC allows large amounts of rutin to be adsorbed,thereby increasing the concentration of rutin at the electrode surface.Owing to the synergistic effect of the 3D CoWO_(4) nanosheets and PC,the developed electrochemical sensor was employed to quantitively determine rutin with high stability and sensitivity.The sensor showed a good linear range(5-5000 ng/mL)with a detection limit of 0.45 ng/mL.The developed sensor was successfully applied to the determination of rutin in crushed tablets and human serum samples.

The SMAD2/miR-4256/HDAC5/p16^(INK4a) signaling axis contributes to gastric cancer progression

The dysregulation of exosomal microRNAs(miRNAs)plays a crucial role in the development and progression of cancer.This study investigated the role of a newly identified serum exosomal miRNA miR-4256 in gastric cancer(GC)and the underlying mechanisms.The differentially expressed miRNAs were firstly identified in serum exosomes of GC patients and healthy individuals using next-generation sequencing and bioinformatics.Next,the expression of serum exosomal miR-4256 was analyzed in GC cells and GC tissues,and the role of miR-4256 in GC was investigated by in vitro and in vivo experiments.Then,the effect of miR-4256 on its downstream target genes HDAC5/p16^(INK4a) was studied in GC cells,and the underlying mechanisms were evaluated using dual luciferase reporter assay and Chromatin Immunoprecipitation(ChIP).Additionally,the role of the miR-4256/HDAC5/p16^(INK4a) axis in GC was studied using in vitro and in vivo experiments.Finally,the upstream regulators SMAD2/p300 that regulate miR-4256 expression and their role in GC were explored using in vitro experiments.miR-4256 was the most significantly upregulated miRNA and was overexpressed in GC cell lines and GC tissues;in vitro and in vivo results showed that miR-4256 promoted GC growth and progression.Mechanistically,miR-4256 enhanced HDAC5 expression by targeting the promoter of the HDAC5 gene in GC cells,and then restrained the expression of p16^(INK4a) through the epigenetic modulation of HDAC5 at the p16INK4a promoter.Furthermore,miR-4256 overexpression was positively regulated by the SMAD2/p300 complex in GC cells.Our data indicate that miR-4256 functions as an oncogene in GC via the SMAD2/miR-4256/HDAC5/p16^(INK4a) axis,which participates in GC progression and provides novel therapeutic and prognostic biomarkers for GC.

Prevalence and Severity of HBV-Associated Acute-on-Chronic Liver Failure Due to Irregular Medication of Nucleos(t)ide Analogs

Hepatitis B virus(HBV)represents the commonest etiologic agent of acute-on-chronic liver failure(ACLF)in most Asian countries.Nucleos(t)ide analogs(NAs)are effective in the treatment of chronic HBV infections,but may also exacerbate the disease and stimulate its development into HBV-associated ACLF if not used appropriately.The current study aimed to assess the prevalence and severity of HBV-associated ACLF as a result from irregular medication of NAs(IMNA).A total of 1134 individuals with HBV-associated ACLF in nine hospitals in Heilongjiang Province were enrolled in this study between 2005 and 2015.Among these,777 chronic hepatitis B(CHB)and 357 HBV-associated liver cirrhosis cases were classified based on various predisposing factors,including IMNA,HBV reactivation(HBVR),infections,treatment drugs,alcohol use and others(hepatitis C virus,hepatitis E virus,gastrointestinal bleeding and unknown reasons).The percentage and improvement rate were examined.Among individuals with HBV-associated ACLF and CHB,IMNA was found in 9.01%,HBVR in 46.20%,infections in 9.52%,treatment drugs in 14.67%,alcohol in 11.71%,and others in 24.58%as predisposing factors.Improvement rates in cases with IMNA,HBVR,infections,treatment drugs,alcohol and others were 41.43%,58.50%,58.11%,56.14%,53.85%,and 65.97%,respectively.Multivariable analysis showed that IMNA,others,infections,hepatic encephalopathy and hepatorenal syndrome were associated with prognosis.Only IMNA independently predicted HBV-associated ACLF prognosis.Overall,our study demonstrated that the percentage of IMNAinduced HBV-associated ACLF was 12.61%,and worse disease conditions resulted from IMNA compared with other factors.Thus,the suitability of treatment with NAs should be thoroughly evaluated.
