Introduction: The inflammatory mechanisms of COVID-19 suggest that corticosteroids may be beneficial, but their benefits must outweigh their potential risks. The RECOVERY trial results suggest that dexamethasone 6 mg/day (but not other steroids) may confer mortality benefits on ventilated COVID-19 patients. Methods: This is a narrative review of the literature about the use of ciclesonide and dexamethasone for COVID-19 patients. Literature is being created rapidly and this review is offered as a state-of-the-science narration. Results: The SARS-CoV-2 virus is an RNA virus whose RNA is transcribed via open reading frames, making its elimination difficult. Coronaviruses have evolved multiple strategies for proteolytic activation of the spike; viral replication occurs entirely in the cytoplasm. In this connection, the RNA-cleaving endoribonuclease (NSP-15 also known as EndoU) may play a key role by facilitating viral double-stranded RNA recognition by the host’s macrophages. Furthermore, the virus is able to undergo RNA recombination rapidly, enabling it to evade host immunity and develop drug resistance. Ciclesonide is an inhaled corticosteroid that reduces lung inflammation and blocks the activity of specific kinases which may explain its anti-inflammatory effect. Dexamethasone is known to reduce mortality in ventilated COVID-19 patients. Discussion: Systemic corticosteroids were used in previous coronavirus epidemics (SARS and MERS) and pulmonary histology of these patients is similar to those in COVID-19 patients. Acute respiratory distress syndrome is the main cause of death in most COVID-19 infections and steroids may be effective in addressing that condition, brought on by cytokine storm. However, it should be noted that inhaled steroids likely have a narrower window for effect than systemic regimens. Conclusion: Dexamethasone has been proven to confer mortality benefits on ventilated COVID-19 patients and may be used with inhaled ciclesonide, which has few side effects and can be locally metabolized. Further study is needed.
导论:COVID-19的炎症机制表明,皮质类固醇可能是有益的,但其益处必须大于其潜在风险。RECOVERY试验结果表明,地塞米松6mg /天(但不包括其他类固醇)可能会降低COVID-19通气患者的死亡率。方法:回顾性分析新冠肺炎患者使用环来奈德和地塞米松的相关文献。文学正在迅速地被创造出来,这篇评论是作为一种最新的科学叙述提供的。结果:SARS-CoV-2病毒是一种RNA病毒,其RNA通过开放阅读框转录,使其难以被清除。冠状病毒已经进化出多种蛋白水解激活刺突的策略;病毒复制完全发生在细胞质中。在这方面,RNA切割核糖核酸内切酶(NSP-15,也称为EndoU)可能通过促进宿主巨噬细胞对病毒双链RNA的识别发挥关键作用。此外,该病毒能够快速进行RNA重组,使其能够逃避宿主免疫并产生耐药性。环来奈德是一种吸入性皮质类固醇,可减轻肺部炎症并阻断特定激酶的活性,这可能解释了其抗炎作用。已知地塞米松可降低COVID-19通气患者的死亡率。讨论:在以前的冠状病毒流行(SARS和MERS)中使用了全身皮质类固醇,这些患者的肺部组织学与COVID-19患者相似。急性呼吸窘迫综合征是大多数COVID-19感染的主要死亡原因,类固醇可能有效治疗这种由细胞因子风暴引起的疾病。然而,应该注意的是,吸入类固醇可能比全身治疗有更窄的效果窗口。结论:地塞米松已被证实可降低COVID-19通气患者的死亡率,可与吸入式环来奈德联合使用,环来奈德副作用少,可局部代谢。需要进一步的研究。

The purpose of this study was to evaluate the palatability of dry syrups for pediatric use by human gustatory sensation testing and the artificial taste sensor. The bitterness intensities of dry syrups mixed with various beverages were also evaluated using the taste sensor. Twenty dry-syrup formulations of antibacterial and anti-allergic drugs containing bitter active ingredients, frequently used in pediatric medicine in Japan, were selected for testing. The main factors influencing palatability were determined by factor analysis of data from human gustatory sensation testing using the semantic differential method. It was shown that the bitterness intensity of dry syrups in water could be predicted by the artificial taste sensor. The influence of different beverages (orange juice, milk or cocoa) mixed with the dry syrups was evaluated using the artificial taste sensor. Taste and texture were found to be the principal factors influencing the palatability of dry syrups. While the bitterness intensities of some dry syrups were increased by mixing with orange juice, the bitterness intensities of most dry syrups were decreased by mixing with milk or cocoa. This suggests that one or more constituents of milk or cocoa may reduce the bitterness intensities of dry syrups.
本研究的目的是通过人的味觉感觉测试和人工味觉传感器来评估儿童用干糖浆的适口性。用味觉传感器对干糖浆与各种饮料混合后的苦味强度进行了评价。本研究选取了日本儿科医学中常用的20种含有苦味活性成分的抗菌和抗过敏药物干糖浆配方进行测试。利用语义差分法对人体味觉测试数据进行因子分析,确定影响其适口性的主要因素。实验结果表明,用人工味觉传感器可以预测干糖浆在水中的苦味强度。用人工味觉传感器评价了不同饮料(橙汁、牛奶或可可)与干糖浆混合的影响。口感和质地是影响干糖浆适口性的主要因素。与橙汁混合后,一些干糖浆的苦味强度有所增加,而与牛奶或可可混合后,大多数干糖浆的苦味强度有所降低。这表明牛奶或可可中的一种或多种成分可能会降低干糖浆的苦味强度。

Quality Evaluation of Carnitine for Proper Use of Supplement 肉碱的质量评价与合理使用
Pub Date : 2021-01-01 DOI: 10.4236/PP.2021.122005

In recent years, consumers are becoming more health-conscious. Supplements are becoming popular as they can be purchased easily. In Japan, the “Food with Function Claims” system began in 2015; the market for supplements is expected to continue to expand. However, the use of some supplements has not been supported with sufficient scientific evidence; some products have even caused health problems. In addition, consumers may not be able to make correct decisions based on the information from the Internet. Unlike medicine, the instruction on the usage of supplements is not precise. Therefore, improving the quality of the information on the supplements will become more necessary in the future. This study aims to improve the quality of the information on supplements by surveying the disintegration and dissolution behavior of the carnitine-containing supplements and evaluated their quality. The products tested here were supplements containing commercial carnitine. Disintegration test and dissolution test were conducted according to the Japanese Pharmacopoeia. Carnitine was quantified by high-performance liquid chromatography. The disintegration tests revealed that the products had different disintegration times, varying from 35 to 100 minutes; some products took more than 5 hours to disintegrate. Thus, some products had a slow rise in their dissolution rate. These results suggest that the carnitine-containing supplements used in this study may affect the absorption process. Therefore, in the case of oral administration, the expected effect might not be achieved depending on the product.
近年来,消费者的健康意识越来越强。补品越来越受欢迎,因为它们很容易买到。在日本,“功能声明食品”制度始于2015年;预计补充剂市场将继续扩大。然而,一些补充剂的使用并没有足够的科学证据支持;一些产品甚至造成了健康问题。此外,消费者可能无法根据互联网上的信息做出正确的决定。与药物不同,补充剂的使用说明并不精确。因此,今后提高补充剂信息的质量将变得更加必要。本研究旨在通过对含肉碱补充剂的崩解和溶出行为进行调查,并对其质量进行评价,以提高补充剂信息的质量。这里测试的产品是含有商业肉碱的补充剂。崩解试验和溶出试验按日本药典进行。采用高效液相色谱法定量测定肉碱含量。崩解试验表明,产品崩解时间不同,从35分钟到100分钟不等;有些产品需要5个多小时才能分解。因此,有些产物的溶出率上升缓慢。这些结果表明,本研究中使用的含有肉碱的补充剂可能会影响吸收过程。因此,在口服给药的情况下,根据产品的不同,可能无法达到预期的效果。

The objective of this study is to isolate, identify and investigate the pharmacological activities of the endophytic fungi from an aquatic plant Aponogeton undulatus Roxb. (A. undulatus). Endophytic fungi were isolated and identified based on morphological characters. The molecular identification of the fungal isolates was performed using by analyzing the DNA sequence based on mega BLAST program. Spectrums of antibacterial and antifungal activities were studied by Agar diffusion methods. Extracts of the endophytic fungal strains isolated from the plant A. undulatus were screened for probable cytotoxic activities using brine shrimp lethality bioassay. Six endophytic fungi, namely AULE-1, AULE-2, AULE-3, AURE-1, AURE-3 and AURE-4 were isolated and purified from the leaves and roots of the plant such as strains AULE-1 as Trichooderma sp., AULE-2 as Carvularia sp. AULE-3 as Penicillium sp. strains AURE-1 and AURE-4 as Fusarium sp. and AURE-3 as Mucor sp. Strain AURE-4 was further identified as Fusarium solani. At 300 μg/disc concentration, six ethyl acetate extracts of endophytic fungi of the plant A. undulates showed moderate to significant activities against most of the test bacteria and pathogenic fungi. The strain AURE-4 exhibited strong cytotoxic activities (10.18 μg/mL) compared to the standard antitumor agent vincristine sulphate and this positive result suggests that fungal extracts may contain antitumor or pesticidal compounds. This is the first study to report the isolation, identification, antimicrobial and cytotoxic properties of endophytic fungi of Aponogeton undulatus Roxb. in Bangladesh.

Immense changes have been introduced in psoriasis treatment, including successful systemic treatment of inflammation and education of psoriatic patients. The focus of this review is the latest developments in the understanding of the aetiopathogenesis of psoriasis, the significance of its comorbidities, treatment possibilities and long-term management using the latest insight provided by pharmacogenetics and identification of biomarkers. The successful control of the disease leads to reduction of myocardial infarction and long-term cardiovascular risk but is usually achieved after various therapeutic attempts until the best-matched treatment for the individual is identified. There is a high unmet medical need for revealing biomarkers associated with disease prognosis, comorbidities, response to therapy and adverse effects. More studies have to be performed for identification and validation of biomarkers and implementation of personalized medicine into clinical practice.
银屑病的治疗已经发生了巨大的变化,包括成功的全身炎症治疗和银屑病患者的教育。本文的重点是利用药物遗传学和生物标志物鉴定提供的最新见解,了解牛皮癣的病因,其合并症的意义,治疗可能性和长期管理的最新进展。疾病的成功控制导致心肌梗死和长期心血管风险的减少,但通常是在各种治疗尝试之后实现的,直到确定最适合个体的治疗方法。揭示与疾病预后、合并症、治疗反应和不良反应相关的生物标志物是一个高度未满足的医学需求。必须进行更多的研究来鉴定和验证生物标志物,并在临床实践中实施个性化医疗。

Recent ethnopharmacological data cited Senna siamea as one of the most widely used medicinal plants in the management of salmonellosis in Benin. However, data related to its activity on non-typhoidal Salmonella spp are limited. This study aimed to assess the antibacterial activity of Senna siamea on multidrug-resistant Salmonella. Ethanolic and aqueous extracts of S. siamea were tested for their antibacterial activity on four multidrug-resistant Salmonella: Salmonella Typhimurium ATCC 14028 and three Salmonella spp. isolated from animals intended for human consumption in Benin. Well diffusion technique combined with the determination by microdilution of Minimum Bactericidal Concentration (MBC) and Minimum Inhibitory Concentration (MIC) were used for antibacterial testing. From antibacterial testing, inhibition diameters of the extracts ranged from 7 to 11 mm, for the susceptible strains. Colistin (reference antibiotic) was active on all Salmonella spp. with inhibition diameters between 18 and 19 mm. The MICs ranged from 3.125 to 25 mg/ml while MBCs of the extracts are greater than 100 mg/ml, so none of the extracts have antibacterial power (p.a). From these results, it appears that the use of Senna siamea in the traditional treatment of salmonellosis is justified. These results must be valued in the development of anti-salmonella phytomedicines.
最近的民族药理学数据指出,塞纳是贝宁沙门氏菌病管理中使用最广泛的药用植物之一。然而,有关其对非伤寒沙门氏菌活性的数据有限。本研究旨在评价番泻草对耐多药沙门氏菌的抑菌活性。本文对四种多重耐药沙门氏菌(鼠伤寒沙门氏菌ATCC 14028)和三种从贝宁供人食用动物中分离的沙门氏菌)的乙醇提取物和水提取物进行了抑菌活性测试。采用孔扩散法结合微量稀释法测定最小杀菌浓度(MBC)和最小抑菌浓度(MIC)进行抑菌试验。抑菌试验结果表明,提取物对敏感菌的抑菌直径为7 ~ 11 mm。粘菌素(参比抗生素)对所有沙门氏菌均有抑制作用,抑制直径在18 ~ 19 mm之间。mic值为3.125 ~ 25 mg/ml,而MBCs值均大于100 mg/ml,均不具有抑菌力(p.a)。从这些结果来看,在沙门氏菌病的传统治疗中使用番泻是合理的。这些结果在开发抗沙门氏菌植物药时必须加以重视。

Objective: To evaluate the synergistic effect of a Selective Serotonin Reuptake Inhibitor (SSRI) and a Selective Cyclooxygenase 2 Inhibitor (ISCOx-2) in the management of After Rachianesthesia Headache in Obstetric Care. Patients and Methods: This was an experimental double-blind, randomized, multi-center clinical trial of non-inferiority clinical trials over a 12-month period (May 1, 2018 to April 30, 2019) in six hospitals in southeastern DR Congo, including all patients undergoing surgery or analgesia on spinal anesthesia for obstetrical indication and with headache characteristic of a dural breccia, with no known causes, contraindications to experimental products and informed consent to been obtained. The patients were divided into four different groups depending on the protocol used, namely: Group A = Rehydration + Paracetamol, Group B = Rehydration + Celecoxib, Group C = Rehydration + Nefopam and Group 4 = Rehydration + Celecoxib + Nefopam (Study Group). Using the Statview II software, the statistical analyzes of data obtained from the different tests were made using the ANOVA test for comparing the averages of different samples using the Fisher test. Verification of the normality of the samples was made by the Kurtosis and Skewness flattening and asymmetry test. Results: The protocol associating Celecoxib and Nefopam significantly demonstrates its effectiveness in reducing CPRAOs in the first two days with a gradual decrease in anxiety and length of stay. In addition, the majority of patients (75.6%) had a high overall level of satisfaction with this protocol. Conclusion: The Nefopam-Celecoxib combination shows its effectiveness in the early reduction of these CPRAOs, anxiety and length of stay with a high overall level of patient satisfaction. Given the good tolerance and accessibility of these products, we strongly suggest the use of this protocol for its validation in our environment and elsewhere, although it is desirable to continue research on other non-explored alien pathways.
目的:评价选择性5 -羟色胺再摄取抑制剂(SSRI)和选择性环氧化酶2抑制剂(ISCOx-2)在产科护理中治疗腰麻后头痛的协同作用。患者和方法:这是一项为期12个月的实验性双盲、随机、多中心临床试验(2018年5月1日至2019年4月30日),在刚果民主共和国东南部的六家医院进行的非劣效性临床试验,包括所有因产科指征而接受脊髓麻醉手术或镇痛的患者,并伴有硬脑膜角化的头痛特征,无已知原因,实验产品的禁忌症,并获得知情同意。根据治疗方案将患者分为4组,即:A组=补液+扑热息痛,B组=补液+塞来昔布,C组=补液+奈福泮,4组=补液+塞来昔布+奈福泮(研究组)。使用Statview II软件,对不同检验获得的数据进行统计分析,采用方差分析检验,比较不同样本的平均值,采用Fisher检验。通过峰度和偏度的平坦化和不对称检验来验证样品的正态性。结果:将塞来昔布和奈福泮联合使用的方案显着表明其在头两天减少CPRAOs的有效性,并逐渐减少焦虑和住院时间。此外,大多数患者(75.6%)对该方案总体满意度较高。结论:奈福泮-塞来昔布联合用药在早期降低患者CPRAOs、焦虑和住院时间方面具有较好的效果,患者总体满意度较高。鉴于这些产品的良好耐受性和可及性,我们强烈建议在我们的环境和其他地方使用该协议进行验证,尽管希望继续研究其他未探索的外星途径。

This investigation was undertaken to enhance the solubility and consequent antibacterial activity of cefuroxime axetil (CA), a β-lactamase-stable broad spectrum second generation cephalosporin through solid dispersion (SD) technique. For this purpose, CA loaded SDs (CSDs) were prepared by solvent evaporation method using different concentrations of microcrystalline cellulose (MCC) as carrier. The CSDs were characterized by in-vitro dissolution study, thermal analysis (DSC), crystallinity (PXRD), interactions (FTIR) and morphology (SEM). Among the formulations, CSD-2 showed the highest dissolution rate which was 2.59-fold higher than pure CA with a drug-carrier (CA: MCC) ratio of 1:3. Enhanced dissolution rate was attributed to conversion of drug from crystalline to amorphous state during preparation of SDs, which was validated by DSC, PXRD, FTIR and SEM analyses. Antibacterial activity of CSD-2 against Staphylococcus aureus (ATCC 25923) and Escherichia coli (ATCC 25922) showed 1.94- and 6.75-fold higher relative zone of inhibition (RZOI), respectively than pure CA. CSD-2 has been found to be the most effective optimized formulation in terms of both enhanced dissolution rate and antibacterial activity. Thus, it can be an effective alternative to conventional dosage forms of CA. However, further investigations are needed to validate its pharmacokinetic properties, in-vivo antibacterial efficacy and safety before recommending as a novel formulation
采用固体分散体(SD)技术对β-内酰胺酶稳定的广谱第二代头孢菌素头孢呋辛酯(CA)的溶解度和抗菌活性进行了研究。为此,以不同浓度的微晶纤维素(MCC)为载体,采用溶剂蒸发法制备了CA负载SDs (CSDs)。通过体外溶出度、热分析(DSC)、结晶度(PXRD)、相互作用(FTIR)和形貌(SEM)对CSDs进行了表征。其中,CSD-2溶出率最高,为纯CA的2.59倍,药物载体(CA: MCC)比为1:3。通过DSC、PXRD、FTIR和SEM分析,证实了SDs制备过程中药物由晶态转化为非晶态导致了溶解速率的提高。与纯CA相比,CSD-2对金黄色葡萄球菌(ATCC 25923)和大肠杆菌(ATCC 25922)的相对抑制区(RZOI)分别高1.94倍和6.75倍。在提高溶出率和抗菌活性方面,CSD-2是最有效的优化配方。因此,它可以作为传统CA剂型的有效替代品。然而,在推荐作为一种新剂型之前,需要进一步的研究来验证其药代动力学特性、体内抗菌功效和安全性

The change of drug quality of Yuxingcao injection after formulation is considered as one of the causes for adverse reactions. In this study, orthogonal experimental design was used to investigate the influencing factors on the pH stability of Yuxingcao injection. Two methods of accelerated tests were carried out in the experiments. The results showed that using Tween 80 as the solubilizer could significantly decrease the pH value of Yuxingcao injection after accelerated tests. There was no significant difference in the pH value after the accelerated tests when the other 6 factors varied, including the type of liquid processed, the dosage of activated carbon, heating temperature, reagents for pH adjustment, pH value range after adjustment, and sterilization conditions. In order to improve the quality stability of Yuxingcao injection, the quality of Tween 80 should be strictly controlled to minimize the change of pH value of Yuxingcao injection.
鱼腥草注射液配制后的药品质量变化被认为是引起不良反应的原因之一。本研究采用正交试验设计,探讨影响鱼腥草注射液pH稳定性的因素。实验中采用了两种加速试验方法。加速试验结果表明,以吐温80为增溶剂可显著降低鱼腥草注射液的pH值。当处理液的种类、活性炭的投加量、加热温度、调整pH的试剂、调整后的pH值范围、灭菌条件等6个因素发生变化时,加速试验后的pH值无显著差异。为提高玉星草注射液的质量稳定性,应严格控制Tween 80的质量,尽量减少玉星草注射液pH值的变化。

Methanolic extract of the leaves of Bridelia stipularis was studied. From this study, we isolated three known flavonoids. They were identified as 7-O-methyl luteolin, apigenin and 5, 7, 2’, 5’ tetrahydroxyflavone by NMR spectroscopic studies. All of them are first time documented for this plant. Different solvent fractions were subjected to in vitro antioxidant and cytotoxicity studies. Both apigenin and ethyl acetate soluble fraction of Bridelia stipularis showed strong antioxidant activity having IC50 value of 8.005, 8.77 μg/mL respectively. Chloroform soluble fraction of Bridelia stipularis exerted the highest toxicity to brine shrimp and petroleum ether soluble fraction showed moderate toxicity having LC50 value of 1.05, 1.71 μg/mL respectively.
