Incidence Rate of Bee Venom Acupuncture Related Anaphylaxis: A Systematic Review.

BACKGROUND: Bee venom acupuncture (BVA) is an effective treatment method for various diseases. Bee venom, however, can cause adverse effects, even rarely including life-threatening anaphylaxis, so safety-related evidence is required. In this study, we systematically estimated the incidence rate of anaphylaxis in response to BVA. METHODS: We searched eight databases (MEDLINE (Pubmed), EMBASE, Cochrane Central Register of Controlled, KISS, KMBASE, Koreamed, OASIS, and NDSL) and systematically reviewed the articles that met the inclusion/exclusion criteria. RESULTS: Among 225 potentially relevant articles, 49 were selected for this study. The overall incidence rate of anaphylaxis in response to BVA was 0.045% (95% CI 0.028-0.062). Women (0.083%, 95% CI 0.010-0.157) showed a higher incidence rate than men (0.019%, 95% CI -0.018 to 0.055), while the incidence for patients who had a skin test conducted (0.041%, 95% CI 0.011-0.072) was not significantly different compared to that obtained for patients for which there was no information about a skin test (0.047%, 95% CI 0.026-0.067). The publication year affected the incidence rate: it was highest before 1999 (1.099%, 95% CI -1.043 to 3.241), lower between 2000 and 2009 (0.049%, 95% CI 0.025-0.073), and lowest between 2010 and 2021 (0.037% 95% CI 0.014-0.060). CONCLUSIONS: In this study, we provide reference data about risk size and factors of BVA-related anaphylaxis, which is essentially required for BVA application in clinics.

Gyejibokryeong-Hwan improves recovery of injured muscles in mouse model of muscle contusion.

OBJECTIVE: To investigate the effects of Gyejibokryeong-Hwan (Guizhifuling-wan, GBH) on muscle injury in a mouse model of muscle contusion. METHODS: C57/BL6 mouse biceps femoris muscles were injured using the drop-mass method and injured animals were treated orally with GBH (50, 100, or 500 mg/kg) once a day for 7 d. Open field and treadmill running tests were performed to assess functional recovery from muscle injury. The production of pro-inflammatory cytokines was examined by enzyme-linked immunosorbent assay and Western blotting analysis. Expression of the muscle regeneration biomarkers, myoblast determination (MyoD), myogenic factor 5 (Myf5), and smooth muscle actin (α-SMA), in the biceps femoris muscle was investigated at the protein and mRNA level by Western blotting and real time-PCR, respectively. Histological analysis was performed using hematoxylin and eosin staining. Finally, myosin heavy chain production was investigated in differentiated C2C12 myoblasts in the presence of GBH. RESULTS: GBH treatment markedly improved locomotion and running behavior. GBH significantly inhibited the secretion of monocyte chemoattractant protein-1 into the bloodstream in muscle-contused animals. The levels of MyoD, Myf5, and α-SMA protein and mRNA were significantly up-regulated by GBH in injured muscle tissue. Histological studies suggested that GBH facilitated recovery from muscle damage. However, GBH did not induce the production of myosin heavy chain in vitro. CONCLUSION: Overall, the present study suggested that GBH improves the recovery of the injured muscles in the mouse model of muscle contusion.

Effect of the residual silanol group protection on the liquid chromatographic resolution of racemic primary amino compounds on a chiral stationary phase based on optically active (3,3'-diphenyl-1,1'-binaphthyl)-20-crown-6.

A liquid chromatographic chiral stationary phase (CSP) based on (3,3'-diphenyl-1,1'-binaphthyl)-20-crown-6, which has been utilized in the resolution of alpha-amino acids, amines and amino alcohols, was treated with excess of n-octyltriethoxysilane to prepare a new improved CSP. The residual silanol groups of the original CSP were protected by n-octyl groups in the new CSP. The chiral recognition ability of the new CSP was superior to that of the original CSP in the resolution of alpha-amino acids, amines and amino alcohols. Retention factors (k1) for the resolution of alpha-amino acids were lower on the new CSP than on the original CSP while those for the resolution of amines and amino alcohols were higher on the new CSP than on the original CSP. The improved chiral recognition ability of the new CSP and the retention behaviors of the two enantiomers on the new CSP have been rationalized to stem from the removal of the non-enantioselective interactions between the analytes and the residual silanol groups of the original CSP and the improved lipophilicity of the CSP.

Complete genome sequencing of a recombinant strain between human astrovirus antigen types 2 and 8 isolated from South Korea.

Human astroviruses (HAstVs) occur worldwide and are known to the causative agents of diarrhea in infants and elderly patients with immune dysfunction. This study aimed to identify recombinant HAstV strains and characterize rare genotypes. The full-length genome of a recombinant HAstV strain isolated from the stool sample of a patient with acute gastroenteritis from South Korea was amplified using three pairs of previously designed primers and seven newly designed primers. The recombinant HAstV was 6757-bp long and contained three sequential open reading frames (ORFs), designated as ORF1a (2781 bp), ORF1b (1548 bp), and ORF2 (2349 bp). Our findings suggested that a recombination event had occurred between ORF1b and ORF2 of the isolated strain, with a recombination breakpoint at 4081 bp. To our knowledge, this is the first study to reveal the complete nucleotide sequence of a recombinant HAstV strain from South Korea. Our study findings might be useful for identifying other recombinant HAstV strains and for developing vaccines against this pathogenic virus.

Liquid chromatographic resolution of beta-amino acids on CSPs based on optically active (3,3'-diphenyl-1,1'-binaphthyl)-20-crown-6.

Two chiral stationary phases (CSPs) based on optically active (3,3'-diphenyl-1,1'-binaphthyl)-20-crown-6 covalently bonded to silica gel were utilized for the first time for the resolution of racemic beta-amino acids using high performance liquid chromatography. All of the 10 beta-amino acids tested were resolved on the CSP containing residual silanol-protecting n-octyl groups, while only five beta-amino acids were resolved on the CSP containing residual silanol groups. The superiority of the CSP containing residual silanol-protecting n-octyl groups and the characteristic retention behaviors of the two enantiomers on the CSP were rationalized to stem from the removal of the residual silanol groups, which can otherwise induce the non-enantioselective retention of the analytes, and the improved lipophilicity of the CSP. The elution orders of the two enantiomers of beta-amino acids were identical on the two CSPs and, consequently, it was concluded that the two CSPs were concluded to utilize identical chiral recognition mechanisms. The different elution orders of the analytes were proposed to be attributed to the presence or absence of pi-pi interactions between the CSP and analytes.
