Clinical characteristics of definite vestibular migraine diagnosed according to criteria jointly formulated by the Bárány Society and the International Headache Society

Abstract Objective: To investigate the clinical features of patients with definite vestibular migraine (dVM). Methods: A total of 91 patients with vestibular symptoms accompanied by migraines/migrainelike symptoms were enrolled and diagnosed according to the criteria of the Bárány Society and the International Headache Society. Baseline data were collected. Videonystagmography and immune-related laboratory tests were performed. Results: Among the 91 patients, 62 (68.1%) had dVM (11 men, 51 women). Among dVM patients, migraine occurred earlier than vestibular symptoms in 42 (67.7%) patients. Spontaneous vertigo occurred in 41 (66.1%) patients. Induced vertigo occurred in 21 (33.9%) patients. Motion sickness occurred in 33 (53.2%) patients. Central oculomotor dysfunction was observed in 11 (17.7%) patients. Caloric test revealed unilateral horizontal semicircular canal dysfunction in 12 (19.4%) patients. Severe intolerance during the test occurred in 44 (71.0%) patients with dVM. 12 (19.4%) patients showed abnormal immune-related indicators. Conclusion: dVM is more common in women. The onset of migraine precedes that of vestibular symptoms, which are often accompanied by photophobia and phonophobia. Motion sickness and severe caloric test intolerance can contribute to the diagnosis of dVM. Immunological indicators are abnormal in some patients with dVM, dVM may be secondary or an accompanying disorder, but the causal relationship needs further investigation. Level of evidence: IV.

Determining the protective effects of Ma-Mu-Ran Antidiarrheal Capsules against acute DSS-induced enteritis using 16S rRNA gene sequencing and fecal metabolomics / 中国天然药物

Ma-Mu-Ran Antidiarrheal Capsules (MMRAC) is traditional Chinese medicine that has been used to treat diarrhea caused by acute enteritis (AE) and bacillary dysentery in Xinjiang (China) for many years. However, the potential therapeutic mechanism of MMRAC for AE and its regulatory mechanism on host metabolism is unclear. This study used fecal metabolomics profiling with GC/MS and 16S rRNA gene sequencing analysis to explore the potential regulatory mechanisms of MMRAC on a dextran sulfate sodium salt (DSS)-induced mouse model of AE. Fecal metabolomics-based analyses were performed to detect the differentially expressed metabolites and metabolic pathways. The 16S rRNA gene sequencing analysis was used to assess the altered gut microbes at the genus level and for functional prediction. Moreover, Pearson correlation analysis was used to integrate differentially expressed metabolites and altered bacterial genera. The results revealed that six intestinal bacteria and seven metabolites mediated metabolic disorders (i.e., metabolism of amino acid, carbohydrate, cofactors and vitamins, and lipid) in AE mice. Besides, ten altered microbes mediated the differential expression of eight metabolites and regulated these metabolisms after MMRAC administration. Overall, these findings demonstrate that AE is associated with metabolic disorders and microbial dysbiosis. Further, we present that MMRAC exerts protective effects against AE by improving host metabolism through the intestinal flora.

Therapeutic effect and mechanism of Erhuang quzhi granules on non-alcoholic fatty liver disease in mice / 药学学报

Erhuang quzhi compounds is one of the protecting liver and inhibiting toxin prescriptions series summarized by Jinqi Yuan and other famous doctors of traditional Chinese medicine during the long-term clinical practice. It is very effective for non-alcoholic fatty liver disease (NAFLD), but its mechanism is not clear. This research investigated mechanism of Erhuang quzhi granules (EQG) in the treatment of NAFLD. All the animal welfare and experimental procedures are in accordance with the regulations of the Animal Ethics Committee of the First Affiliated Hospital of Shihezi University. Mouse models of NAFLD were established by feeding with methionine and choline deficient diet (MCDD) for five weeks. While feeding MCDD, the treatment groups were given EQG (16.25 g·kg-1·d-1) and atorvastatin (ATO, 7.20 mg·kg-1·d-1) by gavage. The effects of EQG on serum biochemical indices, liver pathological changes, and inflammatory cytokines in mice of NAFLD were investigated. Quantitative real-time PCR (qPCR), immunocytochemistry (ICH) and Western blot assays were used to detect the levels of mRNA and protein associated with nuclear factor kappa B/Nod-like receptor protein 3 (NF-κB/NLRP3) in liver. The results showed that EQG significantly reduced the levels of aspartate aminotransferase (AST) and alanine aminotransferase (ALT), and improved the level of low-density lipoprotein cholesterol (LDL-C). The result of hematoxylin-eosin (HE) staining showed that EQG reduced lipid deposition in livers of mice. Meanwhile, EQG notably decreased the levels of interleukin (IL)-1β, IL-6, IL-18 and tumor necrosis factor-α (TNF-α), and mRNA levels of NF-κB, NLRP3, IL-1β, TNF-α, down-regulated the expression of F4/80, IκB kinase β (IKKβ), NLRP3 and apoptosis-associated speck-like protein containing a CARD (ASC) and inhibited the activation of NF-κB and cysteinyl aspartate specific proteinase-1 (caspase-1). These findings announced that EQG could improve NAFLD via NF-κB/NLRP3 pathway possibly, which provides a theoretical basis for the further development and utilization of EQG in clinic.

Luteolin inhibits H2O2 -induced cellular senescence via modulation of SIRT1 and p53

Luteolin, a sort of flavonoid, has been reported to be involved in neuroprotective function via suppression of neuroinflammation. In this study, we investigated the protective effect of luteolin against oxidative stress-induced cellular senescence and its molecular mechanism using hydrogen peroxide (H2O2)-induced cellular senescence model in House Ear Institute-Organ of Corti 1 cells (HEI-OC1). Our results showed that luteolin attenuated senescent phenotypes including alterations of morphology, cell proliferation, senescence-associated β-galactosidase expression, DNA damage, as well as related molecules expression such as p53 and p21 in the oxidant challenged model. Interestingly, we found that luteolin induces expression of sirtuin 1 in dose- and time-dependent manners and it has protective role against H2O2 -induced cellular senescence by upregulation of sirtuin 1 (SIRT1). In contrast, the inhibitory effect of luteolin on cellular senescence under oxidative stress was abolished by silencing of SIRT1. This study indicates that luteolin effectively protects against oxidative stress-induced cellular senescence through p53 and SIRT1. These results suggest that luteolin possesses therapeutic potentials against age-related hearing loss that are induced by oxidative stress.

Pharmacokinetic/pharmacodynamic modeling of the antitumor action of bispecific CD3/EpCAM antibody M701 in human colorectal cancer xenograft mice / 药学学报

M701 is a bispecific CD3/EpCAM T-cell engager antibody for the treatment of malignant ascites. We developed a population pharmacokinetic/pharmacodynamic (PK/PD) model to quantitatively describe and predict the antitumor effect of M701 in human colorectal cancer xenograft mice. We developed the M701 PK model based on plasma concentration data after i.v. administration. A tumor growth model for human colorectal cancer xenograft was developed to evaluate the antitumor effect of M701. We additionally simulated the inhibitory effect of M701 on tumor volume under different dose regimens based on a PK/PD model. A two-compartment model was developed to predict the PK in human colorectal cancer xenograft mice. The relationship between the M701 concentration and tumor growth inhibition was characterized by a combined Simeoni tumor growth/transit compartment model. The estimated pharmacodynamic parameters were related to the tumor growth characteristics λ0 (0.212 d-1) and λ1 (0.044 7 cm3·d-1), to the drug potency k2 (0.071 5 mL·ng-1·d-1), and to the kinetics of tumor cell death k1 (2×10-5 d-1). A model visual predictive check showed that both the PK model and the tumor growth model closely fit the observed data. Simulated tumor growth after administration of M701 (0.5 mg·kg-1 every 6 days and 0.25 mg·kg-1 every 3 days) could be effectively inhibited. This population PK/PD model of M701 provides insight into the antitumor effect of M701 and supports the further therapeutic development of M701.

Study on effect of SuperTab 40LL on compression characteristics of musk sustained-release mini-tablets based on mathematical models / 中国中药杂志

In this paper, co-processed lactose SuperTab 40 LL was selected as fillers to study the preparation of musk sustained-release mini-tablets in the Xihuang multiple-unit drug release system. Musk sustained-release tablets containing different proportions of SuperTab 40 LL and MCC were prepared under various pressures, and then the compressibility and compactibility of these prescriptions were evaluated by Walker, Heckel and Ryshkewitch-Duckworth equations. In addition, the fluidity of the prescriptions was evaluated by parameters of Kawakita equation. There was a comprehensive analysis of the effect of SuperTab 40 LL on musk sustained-release mini-tablets combined with the appearance of SuperTab 40 LL and their tensile strength. The results shown that SuperTab 40 LL had better compression process through the Heckel equation, and the direct compression process of drug powders with excipients can be analyzed by the Kawakita and Ryshkewitch-Duckworth equations. As a new type of co-processed lactose, SuperTab 40 LL had a good fluidity and compactibility. SuperTab 40 LL may undergo particle crushing and plastic deformation during the compression process, which increased the contact area and bonding sites between the particles, and aggregated and shaped the mixed powder easy. Moreover, MCC showed a synergistic effect, and the combined application with SuperTab 40 ll could effectively improve the fluidity and compressibility of the musk sustained-release powder. When the ratio of SuperTab 40 LL and MCC was 2∶1, musk sustained-release mini-tablets had a high drug loading capacity and good compactibility in line with the design objectives.

ObjectivecircRNAs play an important role in tumor development, but the relationship between circRNAs and hepatocellular carcinoma remains to be further explored. The present study aimed to bioinformatically analyze the target gene of microRNA-1. Another aim was to screen circRNAs that are associated with target genes and differentially expressed in hepatocellular carcinoma cells, as well as provide theoretical basis for clinical screening of molecular markers and targeted therapies related to hepatocellular carcinoma.MethodsThe miRNA related database used for the prediction of microRNA-1 target genes, and the bioinformatic analysis of the target genes of microRNA-1 involved functional enrichment analysis and signal transduction pathway enrichment. Then, the circRNAs, which are related to the downstream target genes of microRNA-1, are screened through the circRNA database.ResultsThe number of microRNA-1 target genes was 230 in miRNA related database. Through GO analysis, it was found that the target genes of microRNA-1 had a strong tendency in regulation, and were mainly enriched in three aspects: biological function, biological process and cell localization.The target genes of microRNA-1 are involved in the function of proteins, regulation of biosynthesis, cofactor binding, enzyme regulation and other biological processes. Predicted target genes of miRNA-1 were significantly enriched in cancer signaling pathways, hepatitis B occurrence, endocytosis and splicing pathways. Further, 21 circRNAs related to the target gene of microRNA-1 were found in three circRNA databases, wherein hsa_circ_0004651 was highly expressed in hepatocellular carcinoma cell line HepG2 and its pavent gene was hnRNPD.ConclusionMicroRNA-1 influence the occurrence of hepatocellular carcinoma development through the regulation of protein and enzyme. Hsa_circ_0004651 may affect the development of hepatocellular carcinoma with microRNA-1 and its parental gene hnRNPD.

Objective: To explore the difference of intestinal flora between the patients with acute cerebral hemorrhage due to hyperactivity of liver-Yang and the healthy population. Method: The fecal samples of 9 patients with acute cerebral hemorrhage due to hyperactivity of liver-Yang from the first affiliated hospital of Guangzhou university of traditional Chinese medicine in 2018 were selected as observation group,and 6 stool samples from healthy subjects were selected as the control group.The total bacterial DNA was extracted from the two groups of samples,amplified according to the 16S rRNA V4 region,and paired-end sequencing was performed on the Illumina MiSeq platform.The sequencing results were analyzed by bioinformatics analysis software.The flora composition and structure of the samples from two groups were compared. Result:Venn analysis of operational taxonomic units(OTU) showed significant difference in OTU numbers between the observation group and control group.Partial least squares-discriminant analysis(PLS-DA) showed that there was a significant difference in the composition of intestinal flora between patients with acute cerebral hemorrhage and healthy subjects.On the analysis of species and abundance,at the classification level of phylum,compared with the control group,the ratio of relative abundance values of Firmicutes and Bacteroidetes(F/B) in the observation group was significantly increased,and the relative abundance of Verrucomicrobia was significantly decreased(PPrevotella,Bacteroides,Akkermansia,Blautia and Acidaminococcus(PPBacteroides and Prevotella(B/P) in the observation group was significantly higher than that of the control group;at the classification level of species,there were significant differences between the two groups in P. copri,A. muciniphila,B. ovatus,B. fragilis and Ruminococcus callidus(PPConclusion:Acute cerebral hemorrhage due to hyperactivity of liver-Yang is associated with structural disorder of intestinal flora,which is closely related to the decrease in relative abundance of P. copri and A. muciniphila.

Advance in research of epithelial-mesenchymal transition in adenomyosis / 医学研究生学报

Adenomyosis is a common and difficult gynecological disease, whose etiology is still unclear. It occurs mostly in women aged 30-50 years, which seriously affects the quality of life of women of childbearing age. Epithelial-mesenchymal transition (EMT) can promote the invasion, migration and infiltration of endometrial cells, which is closely related to the occurrence and development of adenomyosis. This article mainly reviews the transcriptional regulation mechanism of EMT, the signal transduction pathway related to EMT and other regulatory factors in adenomyosis.
