Background: Both ginsenoside Re and B-complex vitamins are widely used as nutritional supplements. They are often taken together so as to fully utilize their antifatigue and refreshing effects, respectively. Whether actually a drug-nutrient interaction exists between ginsenoside Re and B-complex vitamins is still unknown. The objective of this study was to simultaneously investigate the effect of B-complex vitamins on the antifatigue activity and bioavailability of ginsenoside Re after their oral administration. The study results will provide valuable theoretical guidance for the combined utilization of ginseng and B-complex vitamins. Methods: Ginsenoside Re with or without B-complex vitamins was orally administered to mice to evaluate its antifatigue effects and to rats to evaluate its bioavailability. The antifatigue activity was evaluated by the weight-loaded swimming test and biochemical parameters, including hepatic glycogen, plasma urea nitrogen, and blood lactic acid. The concentration of ginsenoside Re in plasma was determined by liquid chromatography-tandem mass spectrometry. Results: No antifatigue effect of ginsenoside Re was noted when ginsenoside Re in combination with B-complex vitamins was orally administered to mice. B-complex vitamins caused to a reduction in the bioavailability of ginsenoside Re with the area under the concentration-time curve from zero to infinity markedly decreasing from $11,830.85{\pm}2,366.47h{\cdot}ng/mL$ to $890.55{\pm}372.94h{\cdot}ng/mL$. Conclusion: The results suggested that there were pharmacokinetic and pharmacodynamic drug-nutrient interactions between ginsenoside Re and B-complex vitamins. B-complex vitamins can significantly weaken the antifatigue effect and decrease the bioavailability of ginsenoside Re when simultaneously administered orally.

Yu Hou,Bin Ma,Shanju Yang,Xingya Chen,Yueqing Zheng,Shuangtao Chen 대한기계학회 2015 JOURNAL OF MECHANICAL SCIENCE AND TECHNOLOGY Vol.29 No.5

The stability characteristics of a 25 mm rotor turboexpander with bump-foil journal-gas-bearing pairs and a pair of pressurized thrustbearing are investigated in this study. The journal-gas-bearing pairs in various inner diameters supply radial support for the rotor withdifferent hydrodynamic gas-film thicknesses, and the pair of pressurized thrust bearings balances the axial forces. The experimental resultsreveal that the stability of the bump foil gas bearing is achieved over a wide range of diametric clearances and that an optimal nominaldiametric clearance exists, thus resulting in high rotation speed with small vibration amplitudes. The maximum turboexpander speedreached 93.3 krpm under the nominal diametric clearance of 0 μm with a maximum synchronous amplitude of less than 20 μm.

Toxic Epidermal Necrolysis Induced by Sintilimab: A Case Report

Ya-lei Lye,Bin Shan,Chen-hong Jia,Jiang Liu,Juan Hou,Wen-li Du,Rui Feng,Ping Liang 대한피부과학회 2023 Annals of Dermatology Vol.35 No.-

Sintilimab is an anti-programmed cell death receptor-1 antibody. The phase III clinical trial ORIENT-12 confirmed the safety of sintilimab combined with pemetrexed/platinum in the treatment of advanced squamous non-small cell lung cancer. Skin reactions are the most commonly reported adverse events of immune checkpoint inhibitors and are rarely severe. We describe a case of toxic epidermal necrolysis related to sintilimab in an elderly oncologic patient. 3 weeks after immunotherapy, the patient developed an extensive rash and diffuse itching, rapidly evolving into macules, blisters, bullae and erosions. Causal evaluation was performed based on the algorithm of drug causality for epidermal necrolysis and national Food and Drug Administration qualitative analysis. The patient responded to high-dose glucocorticosteroid and supportive therapy, alongside with local wound care. If immune checkpoint inhibitors need to be extrapolated clinically, strictly following evidence-based research, promptly detecting and treating adverse reactions is crucial.

A hybrid strategy for comprehensive annotation of the protein coding genes in prokaryotic genome

Jia-Feng Yu,Jing Guo,Qing-Bin Liu,Yue Hou,Ke Xiao,Qing-Li Chen,Ji-Hua Wang,Xiao Sun 한국유전학회 2015 Genes & Genomics Vol.37 No.4

Protein coding gene annotation errors in prokaryotic genomes are accumulating continually in bioinformatics databases, while the update rate of genome annotation can not keep up with the explosive increasing genome sequences in most cases. Hence it is critical to manually rectify the genome annotation errors. In this paper, a hybrid strategy by combing the gene ab initio predicting programs and the over annotated gene re-annotation programs is proposed for re-annotation of the protein coding genes in prokaryotic genomes. Based on this strategy, the protein coding genes in Geobacter sulfurreducens PCA is comprehensively re-annotated. As a consequence, 16 hypothetical genes are annotated as non-coding sequences and 104 missing genes are retrieved as protein coding genes. Subsequent function analysis and sequences analysis show that the predicting results are much reliable and robust. Further application to other genomes show that this work can provide alternative tools for later post-process of prokaryotic genome annotations.

Background: To explore the effectiveness and safety of Chinese herbal medicine (CHM) for drug-induced liver injury (DILI) in patients with human immunodeficiency virus (HIV)/acquired immunodeficiency syn- drome (AIDS). Methods: A systematic search was made of eight databases (Pubmed, Cochrane Library, Web of Science, Embase, CNKI, Wanfang, VIP, Sinomed) and two trial registries (WHO ICTRP, ClinicalTrials.gov) from in- ception to September 2022. The effect size was presented as risk ratio (RR) or mean difference (MD) with their 95% confidence interval (CI). The Cochrane Risk of Bias and Grading of Recommendations, Assess- ment, Development and Evaluations (GRADE) tools were used for quality appraisal. Results: Ten randomized controlled trials (RCTs) involving 732 participants were included. Comparing CHM alone with routine treatment, the CHM group showed lower aspartate aminotransferase (MD = -11.47 U/L, 95%CI[-13.05, -9.89], low certainty), lower alanine aminotransferase (MD = -2.68 U/L, 95%CI[-4.27, - 1.08], low certainty), lower total bilirubin (MD = -4.31 mmol/L, 95%CI[-5.66, -2.96], low certainty), lower bilirubin direct (MD = -3.19 mmol/L, 95%CI[-3.87, -2.51], low certainty), and higher effective rate (assessed by symptoms and liver indicators) (RR = 1.13, 95%CI[1.06, 1.20], low certainty). A significant difference was also found in CHM plus routine treatment versus routine treatment in the previous outcomes. No signif- icant difference was found on helper T cells among these comparisons. Only one RCT reported safety of CHM and found no adverse reaction during the trial. Conclusions: CHM may improve the liver function indices and effective rate for HIV/AIDS patients with DILI. However, the sample size was small and quality was low. Larger-samples of high-quality trials are needed.

Association of IgE-mediated allergen sensitivity and promoter polymorphisms of chemokine (C–C motif) ligand 5 gene in Han Chinese patients with allergic skin diseases

Ji-Chang Zhou,Yu-Mei Zhu,Zheng Chen,Shan He,Shi-jie Zheng,Jun-luan Mo,Xiao-Li Liu,Chun-mei Gong,Bin Hou,Hui Yang 한국유전학회 2015 Genes & Genomics Vol.37 No.5

Two single nucleotide polymorphisms (SNPs), rs2280788 (-28C[G) and rs2107538 (-403G[A), in the promoter region of chemokine (C–C motif) ligand 5 (CCL5) was reported to be involved in the immunoglobulin E (IgE) expression and IgE-mediated allergic reactions. This study was to investigate the characteristics of total serum IgE level, specific allergen sensitivities and the two SNPs in the allergic skin disease (ASD) patients. ASD patients visiting the dermatological outpatient department of a local hospital were included with certain criteria, and the fasting venous blood was sampled for analysis. Total serum IgE was assayed with an ELISA kit, and 14 kinds of allergen-specific IgE were tested with an allergen screening system. The polymerase chain reaction–restriction fragment length polymorphism method was used to analyze the two SNPs. Among the finally included 437 patients aged from 16 to 85 years, 68.2 % was positive for the total serum IgE, 49.2 % was positive for at least one of the assayed allergen-specific IgE, and 35.0 % was sensitive to house dust mite. In the SNPs analysis, the GG/(GA?AA) ratio and G/A ratio for the -403G[A locus in the male and/or female C45 years subgroup were significantly lower in the total serum IgE positive patients than in the negative patients (P\0.05). Weak linkage disequilibrium was found between -403A and -28C alleles in male subgroups adjusted by age. Conclusively, house dust mite was the most common allergen in ASD patients, and -403A allele of CCL5 promoter was a risk factor for IgE-mediated sensitization.

Alantolactone is a sesquiterpene lactone isolatedfrom Inula helenium L. Although alantolactone possessesanti-inflammation and apoptosis-induction activities, theunderlying mechanism of anti-cancer effect on humanbreast cancer cells remains largely unknown. In this study,we explored the possibility of alantolactone as an apoptosis-inducing cytotoxic agent using MDA-MB-231 cells asin vitro model. Alantolactone significantly induced itsapoptosis, demonstrated by cell cycle analysis, annexinV-APC/7-AAD double staining and dUTP nick end labeling. Additionally, alantolactone triggered the mitochondrial-mediated caspase cascade apoptotic pathway, whichwas confirmed by increased Bax/Bcl-2 ratio, loss of MMP,release of cytc from mitochondria to cytoplasm, activationof caspase 9/3, and subsequent cleavage of PARP. Z-VADFMKpartially prevented apoptosis induced by alantolactone. Alantolactone provoked the production of ROS, whileNAC (a scavenger of ROS) reversed alantolactone-mediateddepolarization of MMP and apoptosis. Alantolactonemodulated the activities of MAPKs. As expected, cotreatmentwith SB203580, SP600125 or U0126 could reducedthe apoptotic rate. Furthermore, alantolactone decreasedthe protein expressions of p-NF-kB p65 and p-STAT3,increased p-c-Jun level in a dose-dependent manner. Thesefindings suggested that alantolactone possessed anticanceractivity via ROS-mediated mitochondrial dysfunctioninvolving MAPK pathway, and had an effect on the transcriptionfactors of NF-kB, AP-1 and STAT3.
