Solution and Colour Stability of the Bark Extract of Bridelia ferruginea Benth

A solvent system consisting of water: propylene glycol: ethanol (2:2:1) was found suitable for diluting the ethanol bark extract and for reconstituting the freeze-dried extract of Bridelia ferruginea Benth for preparation of a gargle formulation. Such solutions remained clear when subjected to high storage temperatures and eight freeze-thaw cycles. The wine colour of Bridelia bark extract solution darkened on storage. Darkening was accelerated by heat while light had minimal effect. Inclusion of certain antioxidants—sodium metabisulphite, ascorbic acid and citric acid, reduced the colour change. Heating the freeze-dried extract at 115°C for 4 h and at 130°C for at least 1 h arrested the colour change. When lime juice was added to the solution of the heated powder, the colour of the resulting solution became unstable implicating a pH effect on colour stability. The colour of bottle and use of carton for storage had no appreciable effect on colour stability.     

我国中医药健康养老服务模式的实践成果、面临挑战及优化对策

目的分析我国部分地区的中医药健康养老服务模式实践成果,探讨发展我国中医药健康养老服务模式面临的挑战,并提出优化对策。方法分析我国中医药健康养老服务模式的发展背景及优势。收集各地卫生健康委员会官网、中医药管理局官网等公开发布的中医药健康养老相关信息,选取较为典型的9个省市中医药健康服务模式,分析其实践成果及特色。探讨发展中医药健康养老服务模式面临的挑战,提出我国中医药健康养老服务模式的优化对策。结果中医药在我国健康养老服务方面具有“治未病”优势、对重大疾病的诊疗优势。各城市根据地区实情,取得了具有当地特色的实践成果,并形成了家庭养老、社区养老、机构养老及互助型养老等模式,探索出高端养老、旅居养老、技术养老等新模式。发展中医药健康养老服务模式面临行业发展水平参差不齐、中医药养老文化传播力度不足、专业人才匮乏、中医药服务质量有待提高等挑战。建议需从改革创新中医药养老政策机制、优化公共卫生服务并提升基层服务能力、建立分级分类中医药健康养老人才体系、构建标准化服务体系等方面进行优化。结论我国中医药健康养老服务体系建设取得了初步的发展,各地形成了具有当地特色的实践成果,但仍面临多种挑战,尚待从政策机制、公共卫生服务、人才体系建设、服务体系建设等方面进行优化。     

基于社区管理模式探讨家庭医生签约服务模式对空巢老年糖尿病的影响

目的基于社区管理模式探讨家庭医生签约服务模式对空巢老年糖尿病的影响。方法选取2018年3月-2019年7月广西医科大学第二附属医院社区卫生服务中心签约家庭医生服务模式及未签约家庭医生服务模式的空巢老年糖尿病患者各92例,签约家庭医生的患者设为观察组,未签约家庭医生的患者设为对照组。观察并比较2组患者干预前和干预1个月后、干预3个月后、干预6个月后、干预1年后的空腹血糖、糖化血红蛋白及自我管理水平;评估并比较2组血糖达标率、血压达标率、血脂达标率及联合达标率。结果干预后2组糖化血红蛋白和空腹血糖明显降低(P<0.05),且观察组干预3个月后、干预6个月后、干预1年后的糖化血红蛋白和空腹血糖明显低于对照组(P<0.05),重复测量结果显示,观察组糖化血红蛋白和空腹血糖数值下降趋势明显大于对照组(P<0.05);观察组干预后血糖达标率、血压达标率、血脂达标率及联合达标率均明显升高(P<0.05),且明显高于对照组(P<0.05);干预后2组自我管理水平明显升高(P<0.05),观察组干预1个月后、干预3个月后、干预6个月后、干预1年后自我管理水平明显高于对照组(P<0.05);观察组的干预满意度(98.91%)明显高于对照组(90.22%)(P<0.05)。结论家庭医生签约服务模式能够提高社区管理模式中糖尿病空巢老人血糖、血脂、血压的自我管理能力,降低患者糖化血红蛋白及血糖水平,提高患者满意度,有利于糖尿病病情控制。     

An evaluation of the effects of susceptibility changes on the water chemical shift method of temperature measurement in human peripheral muscle

Divergencies between chemical shift measurements of temperature and directly measured values using optical sensors have been studied in vivo in human peripheral muscle with the assistance of a variety of experimental and theoretical techniques. These include the modeling of both thermal and susceptibility changes using two- and three-dimensional finite element methods, as well as the use of multi-wavelength near infrared observations. The conclusion of these studies is that a simple temperature calibration is not accessible, with results affected by the complex response of the tissue itself.     

Prevalence of chronic disease in older adults in multitier eye-care facilities in South India: Electronic medical records-driven big data analytics report

Purpose:To study the prevalence of systemic conditions in older adults, either self-reported or discovered during routine eye examinations, at multitier eye-care facilities over the past decade, and to explore their association with vision and common ocular disorders, including cataract, glaucoma, and retinopathy.Methods:Retrospective review of a large data set compiled from the electronic medical records of patients older than 60 years who presented to an eye facility of a multitier ophthalmology network located in 200 different geographical locations that included urban and rural eye-care centers spread across four states in India over a 10-year period.Results:618,096 subjects aged 60 or older were identified as visiting an eye facility over the 10-year study period. The mean age of the study individuals was 67·28 (±6·14) years. A majority of older adults (66·96%) reported being free of systemic illnesses. Patients from lower socioeconomic status had a lower prevalence of chronic systemic disease, but the presenting vision was poorer. Hypertension (21·62%) and diabetes (18·77%) were the most commonly reported chronic conditions in patients who had concomitant systemic illness with visual concerns.Conclusion:The prevalence of chronic systemic illnesses in older adults presenting to multitier eye-care facilities is relatively low, except in those with diabetic retinopathy. These observations suggest a need to include active screening for common chronic diseases in standalone eye-care facilities to achieve a more accurate assessment of chronic disease burden in the older population.
