Arsenic Content in Cordyceps： A Review / 中国实验方剂学杂志

Cordyceps， a unique precious Chinese herbal medicine in China， has the effects of tonifying the kidney and lungs， stopping bleeding， and resolving phlegm. It has definite clinical effects on diabetes， respiratory diseases （such as chronic obstructive pulmonary disease）， chronic kidney diseases， slow arrhythmia， and hyperlipidemia. We searched China National Knowledge Infrastructure （CNKI）， Wanfang Data， VIP， SpringerLink （Biomedical Sciences）， Embase， Proquest （Life Sciences）， PubMed， Cochrane Library， and SinoMed for the research on the arsenic content in Cordyceps. According to statistical analysis， arsenic in Cordyceps mainly exists in the non-toxic or low-toxic form. The arsenic-containing compounds in Cordyceps may be an arsenic-sugar compound with anticancer effect. The inorganic arsenic content in Cordyceps is lower than the arsenic standard stipulated by the State Food and Drug Administration. It remains uncertain whether different measurement methods can affect the results. The total arsenic content varies in Cordyceps from different producing areas， and the general rule of total arsenic content in Cordyceps produced in different provinces， districts， and counties cannot be obtained from the results of the existing studies. The arsenic content in Cordyceps is mainly concentrated in the insect part， which is significantly different from that in stroma， and no arsenic is detected in the mycelia. The soil arsenic content in the growing areas is generally high， which may be a main reason for the high arsenic content in Cordyceps. As a valuable medicinal material for tonifying and nourishing， Cordyceps still plays an irreplaceable role in disease prevention， health care， chronic disease management， and rehabilitation.

Evaluation of the consistency of four hematology systems / 中华检验医学杂志

Objective:To provide consistent data basis for the application of reference intervals for children blood cell analysis in different testing systems.Methods:According to the requirements of American Institute for Clinical and Laboratory Standardization (CLSI) EP9-A3 document, 45 samples were collected and Sysmex XN20-A1 were used as reference system. Beckman DxH800, Siemens ADVIA 2120i, and Mindray BC5310 were comparison systems. Complete blood count and leukocyte classification were performed by four systems. The outliers of the detection results were tested by the generalized extreme student deviate (ESD) method. An optimal regression model was selected by scatter diagram, deviation diagram and frequency distribution diagram, which was used to fit the regression equation and calculate the deviation at the medical decision level and reference interval. The acceptable range for blood count deviation was cited from the Analytical Quality Specifications for Routine Tests in Clinical Hematology. The acceptable range for leukocyte classification was based on the EQA program of Royal College of Pathologists of Australasia (RCPA).Results:After the outliers were deleted, the scatter plot showed a linear relationship between the reference system and the three comparison systems. The deviation plot showed that the differences were variable. Deming regression or Passing-Bablok regression was selected according to the data distribution. The determination coefficient R2 of reference system and three comparison systems ranged from 0.95 to 0.99 in blood count and leukocyte classification. At the upper and lower limits of the reference interval, the deviations between XN-20A1 and ADVIA 2120 system were all acceptable, except for MONO# at 0.12×10 9/L. The deviations of all parameters at medical decision level were within acceptable ranges. The lower limit of PLT is partially unacceptable at the level of medical decision related to treatment and prognosis. Conclusions:The results of complete blood count and leukocyte classification in reference system and the comparison system had good consistency within the children′s reference interval. Our study provided a scientific basis for the feasibility of adopting a unified reference interval for different detection systems.

Official labeled and unlabeled Brazilian honey. Comparison between physicochemical, microbiological, and microscopic parameters / Miel brasileña oficial etiquetada y no etiquetada. Comparación entre parámetros fisicoquímicos, microbiológicos y microscópicos / Mel brasileiro oficialmente rotulado e não rotulado. Comparação entre parâmetros físico-químicos, microbiológicos e microscópicos

SUMMARY Introduction: Honey is a natural substance produced by bees mainly from flower nectar with high nutritional value. However, many commercialized samples are adulterated or falsified. Method: We bought twelve honey samples in markets in the city of Betim (Brazil) and analyzed their acidity, pH, electrical conductivity, insoluble matter, ashes, moisture content, presence of mesophile bacteria, molds, yeasts, total coliforms, Salmonella spp. and the presence of pollen grains. Results: Considering all honey samples, the average pH was 3.8 ± 0.5 and the average free acidity was 29.8 ± 6.6 mEq/kg. Considering acidity, we found the average of lactonic acidity 6.4 ± 2.4 mEq/kg and a total average acidity of 36.2 ± 6.9 mEq/kg. The average moisture content was 19.4 ± 1.0 %, the average electrical conductivity was 391.6 ± 168.6 μS/ cm, the average amount of ashes was 0.5 ± 0.8 % and the average insoluble matter was 0.08 ± 0.02 %. Only the moisture was significantly different between the two groups and ten honey samples had pollen grains. Conclusions: The quality parameters of the labeled and unlabeled samples were not significantly different, although two samples of unlabeled honey were fraudulent, mainly due to the absence of pollen grains. Identifying the presence or absence of pollen in the samples is a safe, economical, and reliable first step for verifying the authenticity of the honey.

Noninvasive hemoglobin monitoring in clinical trials: a systematic review and meta-analysis / Monitorização não invasiva da hemoglobina em ensaios clínicos: uma revisão sistemática e metanálise

Abstract Background and objectives: The measurement of hemoglobin concentration (Hb) by co-oximetry is an innovative technique that offers efficiency and agility in the processing of information regarding the measurement of Hb obtained through continuous, non-invasive and rapid monitoring. Because of this attribute, it avoids unnecessary exposures of the patient to invasive procedures by allowing a reduction in the number of blood samples for evaluation and other unnecessary therapies. It also helps to make decisions about the need for transfusion and how to handle it. The objective of this study is to compare the performance offered to obtain Hb values between the Masimo Corporation (Irvine, CA, USA) instrument and the standard gold tool (laboratory examination). Contents: The study corresponds to a systematic review followed by meta-analysis, which included fully registered full-text clinical trials published from 1990 to 2018. PubMed, Cochrane, Medline, Embase and Web of Science databases were investigated. The mean overall difference found between the non-invasive and invasive methods of hemoglobin monitoring was 0.23 (95% CI -0.16, 0.62), that is, it did not present statistical significance (p = 0.250). The results of the analysis of heterogeneity within and between the studies indicated high levels of inconsistency (Q = 461.63, p < 0.0001, I2 = 98%), method for Hb values. Conclusions: Although the mean difference between noninvasive measurements of Hb and the gold standard method is small, the co-oximeter can be used as a non-invasive "trend" monitor in detecting unexpected responses at Hb levels.

Resumo Justificativa: A medida da concentração de hemoglobina (Hb)por co-oximetria é uma técnica inovadora que oferece eficiência e agilidade no processamento das informações referentes à medida da concentração de hemoglobina obtida por meio de monitorização contínua, não-invasiva e rápida. Por conta desse atributo, evita exposições desnecessárias do paciente a procedimentos invasivos ao possibilitar redução da quantidade de amostras sanguíneas para avaliação e de outras terapêuticas desnecessárias. Além disso, auxilia a tomada de decisões quanto à necessidade de transfusão e quanto ao manejo da mesma. Objetivo: Comparar o desempenho oferecido para a obtenção dos valores de concentração de hemoglobina entre medida não invasiva da Hb e a ferramenta padrão ouro (exame laboratorial). Conteúdo: O estudo corresponde a uma revisão sistemática seguida de metanálise que incluiu ensaios clínicos devidamente registrados com texto completo, publicados a partir de 1990 até 2018. Foram investigadas as bases de dados PubMed, Cochrane, Medline, Embase e Web Of Science. A diferença média global encontrada entre os métodos não invasivo e invasivo de monitorização da hemoglobina foi de 0,23 (95% IC -0,16; 0,62), ou seja, não apresentou significância estatística (p = 0,250). Os resultados da análise de heterogeneidade dentro e entre os estudos, apontou níveis elevados de inconsistência (Q = 461,63, p< 0,0001, I2 = 98%). Conclusão: Embora a diferença média entre as medidas não invasivas da Hb e o método padrão ouro sejam pequenas, o co-oxímetro pode ser utilizado como um monitor não invasivo de "tendência" na detecção de alterações inesperadas nos níveis de Hb.

SUMMARY This study aimed at evaluating effective methods for breaking the hard and insoluble spores of Ganoderma lucidum to recover functional biomolecules. Rupture techniques were evaluated such as manual maceration (RM), maceration with spheres of various materials (BR), and microwave exposure plus maceration with steel/ chrome spheres (MBR1). Spore rupture was evaluated using UV-Vis spectroscopy, which showed vibrations of 2955, 1642, 1240, 1080 and 1746 cm-1 corresponding to changes in spore walls. The MBR1 extract contained the largest amounts of carbohydrates (19.80 mg.g-1 spores) and polyphenols (2.21 mg.g-1 spores), whereas the BR extract had higher antioxidant activity (57.22%Inb DPPH). The MBR1 and BR extracts contained 62.2 and 73.5% glucose, respectively. Both methods also involved significant extraction of carbohydrates and proteins. The best way to extract biomolecules from spore walls is to perform a microwave heat treatment and break the walls with steel/chrome spheres; this produces large quantities of carbohydrates with antioxidant properties.

RESUMEN El objetivo de este estudio fue evaluar varios métodos de ruptura de las esporas de Ganoderma lucidum y extraer sus propiedades bioactivas. Para este propósito se evaluaron diferentes técnicas de rompimiento como: la maceración manual (RM), la maceración con esferas de diversos materiales (BR) y la exposición a microondas junto la maceración de las esporas con esferas de acero/cromo (MBR1). La ruptura de las esporas fue evaluada por espectroscopia UV-Vis, la cual mostró que las vibraciones 2955, 1642, 1240, 1080 y 1746 cm-1 correspondieron a cambios estructurales en las paredes de las esporas. El extracto MBR1 presento el mayor contenido de carbohidratos (19,80 mg.g-1) y polifenoles (2,21 mg.g-1), mientras que el extracto BR tuvo una mayor actividad antioxidante (57,22% Inb DPPH). Los extractos MBR1 y BR también presentaron en el análisis de monosacáridos un 62,2 y 73,5% de contenido glucosa. Como conclusión la mejor metodología para extraer biomoléculas de las paredes de las esporas de G. lucidum fueron el tratamiento térmico con microondas y la ruptura de las paredes con esferas de acero/cromo, porque este proceso permitió la extracción de una mayor cantidad de carbohidratos con posibles propiedades antioxidantes.

Irisin and troponin I expression in dialysis patients submitted to remote ischemic preconditioning: a pilot study / Expressão de irisina e troponina I em pacientes em diálise submetidos a pré-condicionamento isquêmico remoto: um estudo piloto

ABSTRACT Background: Renal replacement therapy continues to be related to high hospitalization rates and poor quality of life. All-cause morbidity and mortality in renal replacement therapy in greater than 20% per year, being 44 times greater when diabetes is present, and over 10 times that of the general population. Regardless of treatment, the 5-year survival is 40%, surpassing many types of cancers. Irisin is a hormone that converts white adipose tissue into beige adipose tissue, aggregating positive effects like fat mass control, glucose tolerance, insulin resistance, prevention of muscle loss, and reduction in systemic inflammation. Objectives: To determine the serum levels of troponin I in hemodialysis patients submitted to remote ischemic preconditioning (RIPC) associated with irisin expression. Methods: This was a prospective, randomized, double-blind clinical trial with patients with chronic kidney disease submitted to hemodialysis for a 6-month period. Troponin I, IL-6, urea, TNF-α, and creatinine levels were determined from blood samples. The expressions of irisin, thioredoxin, Nf-kb, GPX4, selenoprotein and GADPH were also evaluated by RT-PCR. Results: Samples from 14 hypertensive patients were analyzed, 9 (64.3%) of whom were type 2 diabetics, aged 44-64 years, and 50% of each sex. The difference between pre- and post-intervention levels of troponin I was not significant. No differences were verified between the RIPC and control groups, except for IL-6, although a significant correlation was observed between irisin and troponin I. Conclusion: Remote ischemic preconditioning did not modify irisin or troponin I expression, independent of the time of collection.

RESUMO Introdução: A terapia de substituição renal continua associada a altas taxas de hospitalização e baixa qualidade de vida. A morbimortalidade por todas as causas na terapia de substituição renal é superior a 20% ao ano, sendo 44 vezes maior quando a diabetes está presente e mais de 10 vezes a da população em geral. Independentemente do tratamento, a sobrevida em 5 anos é de 40%, superando muitos tipos de câncer. A irisina é um hormônio que converte tecido adiposo branco em tecido adiposo bege, agregando efeitos positivos como o controle de massa gorda, tolerância à glicose, resistência à insulina, prevenção de perda muscular e redução da inflamação sistêmica. Objetivos: Determinar os níveis séricos de troponina I em pacientes em hemodiálise submetidos ao pré-condicionamento isquêmico remoto (PCIR) associado à expressão da irisina. Métodos: Estudo clínico prospectivo, randomizado, duplo-cego, com pacientes com doença renal crônica submetidos à hemodiálise por um período de 6 meses. Os níveis de troponina I, IL-6, uréia, TNF-α e creatinina foram determinados a partir de amostras de sangue. As expressões de irisina, tioredoxina, Nf-kb, GPX4, selenoproteína e GADPH foram também avaliadas por RT-PCR. Resultados: Foram analisadas amostras de 14 pacientes hipertensos, 9 (64,3%) dos quais eram diabéticos tipo 2, com idades entre 44 e 64 anos e 50% de cada gênero. A diferença entre os níveis pré e pós-intervenção de troponina I não foi significativa. Não houve diferenças entre os grupos PCIR e controle, exceto pela IL-6, embora tenha sido observada correlação significativa entre irisina e troponina I. Conclusão: O pré-condicionamento isquêmico remoto não modificou a expressão de irisina ou troponina I, independentemente do tempo de coleta.

Objective: This study has investigated cosmeceutical properties namely, antibacterial, sun protection factor and total phenolics contents of some selected macrofungi. The studies were conducted on five reference cultures collected from Indian type culture collection center (IMTEC, Chandigarh, India) and five isolates collected from TERI-Deakin Nano Biotechnology Centre facility at TERI Gram, Gurugram, India. Methods: The cosmeceutical properties of the crude extracts from selected macrofungi were analyzed using standard bioassay techniques. Antibacterial activity was analyzed against Staphylococcus epidermidis, Escherichia coli, Micrococcus luteus, Bacillus megaterium, Pseudomonas aeruginosa, Staphylococcus aureus, and Acinetobacter baumannii using Agar well diffusion method. The sun protection factor was estimated and calculated using the Mansur equation. Free radical scavenging activity using DPPH was performed to assess the antioxidant activity of the extracts. Results: Ethyl acetate extracts of the broth from P. florida and TERI-G1 cultures showed a broad-spectrum antibacterial activity against S. epidermidis, E. coli, M. luteus and B. megaterium. Ethyl acetate extracts of the broth from TERI-G3 showed the highest SPF activity of 34.02 at 200 µg. ml-1 concentration. Ethyl acetate extract of the broth from F. velutipes, P. florida, P. ostreatus, and TERI-G1 showed comparable antioxidant activity of 66.86%, 79.51%, 82.02%, and 69.58% respectively when compared to ascorbic acid (85.83%) and quercetin (83.09%) taken as positive control in the study and their total phenolic contents were found to be 6.93, 43.68, 20.88 and 13.77 Gallic acid equivalent (GAE) per gram. The minimal inhibitory concentration of F. velutipes, P. florida, P. ostreatus, and TERI-G1 was found to be 3552.89 µg. ml-1, 1250 µg. ml-1, 2418.9 µg. ml-1 and 3219 µg. ml-1 respectively. Conclusion: The work is in progress to identify and characterize TERI-G1and TERI G3 cultures. Further studies on the anti-inflammatory, anti-tyrosinase, elastase inhibition properties of the cultures will be assessed to identify potential cosmeceutical active ingredients with promising applications in cosmeceutical products.

Potential quality evaluation approach for the absolute growth years' wild and transplanted Astragali Radix based on anti-heart failure efficacy / 中国天然药物

The quality of Astragali Radix (AR) was closely related to the growth period. However, the current commodity grades of AR were only divided by diameter but not directly related to the growth period, which leads to the contradiction between the grade standard and the quality evaluation index. Therefore, solving this problem will be the key for the quality evaluation of AR. The present study established a potential quality evaluation approach for the absolute growth years' wild Astragali Radix (WAR) and transplanted Astragali Radix (TAR) based on the chemical components and anti-heart failure efficacy through adopting a bare-handed sections approach to rapidly identify the growth years of WAR. In this study, the absolute growth years of WAR were obtained by identifying the growth rings of 1-6 growth years root through the methods. The contents of flavonoids and saponins in 2-6 growth years' WAR were determined by HPLC-UV-ELSD. The contents of 12 chemical components and the anti-fatigue failure effects of WAR (4-year-old) and TAR were compared on rat models of heart failure induced by doxorubicin. Meanwhile, NMR-based untargeted metabolomics studies were performed to investigate the regulative effects of WAR and TAR. The result shows that the numbers of growth rings were consistent with the actual growth periods of AR. The HPLC-UV-ELSD determination indicated that the content of total flavonoids in WAR was significantly higher than that in TAR. Pharmacodynamics analysis revealed that the effects of WAR on cardiac function parameters (EF, FS and LVIDs), contents of serum CK and BNP were superior to those of TAR. 13 metabolites of heart were identified that had a higher rate of change in WAR group than TAR. Overall, a rapid identification method for the growth years of WAR was established, and the fact that WAR were significantly better than TAR in the heart failure rats was first proved in the paper. This study provided a scientific basis for establishing a novel commodity specification and grade of AR for clinical rational drug use.
