沈其霖教授辨治肺病经验探析

沈其霖教授擅长诊治慢性咳嗽、过敏性哮喘、肺间质纤维化等肺系疾病。沈教授认为,慢性咳嗽的常见病因为寒邪挟风邪,治以温肺祛风,可加用清热化痰药。过敏性哮喘本虚在肺、脾、肾,标实是风痰,病位在肺,咽喉亦是该病症状最明显之处,治以祛风化痰,固护肺、脾、肾。肺痿以本虚为主,标实为次,治疗应扶正虚、行气滞、化痰浊、祛血瘀,并应加强消散肿结之药,不仅祛邪滞,还可防癌变。

Influence of the spray adjuvant on the toxicity effects of a glyphosate formulation

In the present study, the influence of the spray adjuvant on the toxicity effects of a glyphosate formulation was examined in HEp-2 cell line. We determined the median lethal concentration (LC₅₀) of Atanor® (glyphosate formulation), Impacto® (spray adjuvant) and the mixture of both agrochemicals. We also compared the toxicities of the pesticides individually and in mixture and we analyzed the effects on oxidative balance from each treatment.Our results showed that all the agrochemicals assayed induce dose and time-dependent cytotoxicity and that the toxicity of Impacto® with Atanor® (mixture) was additive on HEp-2 cell line.All the agrochemicals assayed produced an increase in catalase activity and glutathione levels, while no effects were observed for superoxide dismutase and glutathione-S-transferase activities. We found an important increase in ROS production in cells treated with Atanor® and mixture. Besides, all the agrochemicals used triggered caspase 3/7 activation and hence induced apoptosis pathway in this cell line. In conclusion, our results demonstrated that the addition of adjuvant to glyphosate formulation increase the toxicity of the mixture in cell culture. Furthermore, cell culture exposed to agrochemical mixture showed an increased ROS production and antioxidant defenses.     

开胃消食合剂的制备及质量控制简

目的建立开胃消食合剂的质量控制方法。方法将山楂等中药进行提取和纯化后制备成开胃消食合剂;采用薄层色谱法定性鉴别陈皮、槟榔,用薄层扫描法测定方中熊果酸的含量。结果供试品与对照品薄层图谱斑点相同且清晰,开胃消食合剂每1mL含熊果酸不得低于0．20mg。结论该制剂制备工艺合理,方法易操作,质量稳定可控。     

丹参对急性酒精性肝损伤肝组织保护作用的研究

目的观察丹参对酒精所致大鼠急性肝损伤肝组织的保护作用。方法大鼠分为正常组(以正常饮食、饮水喂养)、模型组(连续6天高浓度白酒灌胃)、丹参低、中、高剂量组(白酒灌胃造模后,给予丹参腹腔注射)。9天后处死大鼠,观察大鼠肝脏的组织病理学改变及肝细胞的超微病理学改变。结果模型组大鼠的肝组织呈现明显的水样变性和脂肪变性,并可见少量片状肝细胞坏死。而丹参组肝细胞未见坏死改变,水样变性和脂肪变性程度也较轻,以高剂量丹参组最为显著。结论丹参对急性酒精性肝损伤肝组织有一定的保护作用。

Effects of Bojungikgi-tang on anorexic patients with atopic dermatitis: A protocol for a randomized,usual care-controlled,assessor-blinded,parallel, pilot clinical trial

Background:Anorexia and atopic dermatitis (AD) are highly prevalent diseases, and the herbal medicine Bojungikgi-tang (BJT) has been frequently used for the treatment of both anorexia and AD. However, no study has simultaneously evaluated the effects of BJT for both anorexia and AD.Methods:A prospective, randomized, usual care-controlled, assessor-blinded. parallel, pilot clinical trial has been designed to explore the feasibility, preliminary effectiveness, and safety of BJT for the treatment of anorexic patients with AD. Forty anorexic patients with AD will be randomly assigned (1:1) to BJT or the usual care group. The BJT group will be administered BJT granules twice a day for 8 weeks and followed up for 4 weeks whereas the usual care group will not receive BJT granules. All participants in both groups will be provided with over-the-counter topical corticosteroids as a relief drug. Data will be collected at baseline and at 4, 8, and 12 weeks after randomization. The primary outcome is the score on the anorexia visual analog scale at 8 weeks post-treatment. The secondary outcomes include body weight, body fat percentage, body fat mass, skeletal muscle mass, SCORing of Atopic Dermatitis index, Validated Investigator Global Assessment scale for Atopic Dermatitis, Dermatology Life Quality Index, EuroQoL 5 Dimension 5 Level, deficiency and excess pattern identification questionnaire, total immunoglobulin E, eosinophil count, and frequency and amount of use of topical corticosteroids. Adverse events and laboratory test results will be monitored to assess safety. Fecal samples to check for gut microbiome changes and blood samples to check immune and metabolic markers will be collected before and after taking BJT.Discussion:This is the first trial that explores the preliminary effectiveness and safety of BJT for the treatment of anorexic patients with AD. The results of this pilot study will provide the basic evidence for large-scale, confirmatory, multicenter, high-quality clinical trials.Trial registration:Clinical Research Information Service, KCT0006784 (registered on November 26, 2021).
