四逆汤对实验性高脂血症合并动脉粥样硬化兔血脂及高低密度脂蛋白含量的影响

[目的]观察四逆汤预干预对高脂血症(HLP)合并动脉粥样硬化(AS)兔的TC、TG、HDL-CH、LDL-CH、Apo-A、Apo-B的影响,分析其对高脂血症(HLP)合并动脉粥样硬化(AS)兔血脂及载脂蛋白的调节作用。[方法]通过高脂饲料喂养及免疫损伤法建立兔HLP合并AS模型,分别给予西药(阿托伐他汀)和四逆汤(高、中、低剂量)的治疗方法。运用酶法测定血中TC、TG含量的变化;比色法测定干预后血中LDL-CH、HDL-CH含量的变化;电泳法测干预后血中载脂蛋白A及B含量的变化。[结果]四逆汤中、高剂量组在降低血TG含量与模型组比具有统计学意义(P<0.05);四逆汤高剂量组在降低血TC、LDL、Apo-B含量与模型组比具有统计学意义(P<0.05);在升高血HDL、Apo-A含量,HDL/LDL比值,Apo-A/Apo-B比值方面,四逆汤高剂量组与模型组比具有显著性差异(P<0.01)。[结论]四逆汤各剂量组均能调节实验性HLP并AS兔血脂代谢,降低胆固醇和甘油三酯的含量,且能降低血中低密度脂蛋白和载脂蛋白B的含量,使其高密度脂蛋白、载脂蛋白A升高。四逆汤预防AS形成的作用机制可能与调节血脂代谢,减缓脂质颗粒沉积有关。

The Effects of a Standardized Herbal Remedy Made from a Subtype of Rosa canina in Patients with Osteoarthritis: A Double-Blind, Randomized, Placebo-Controlled Clinical Trial

Background: A standardized rose-hip powder produced from the seeds and husks of fruit from a subtype of Rosa canina has been reported to inhibit leukocyte functions that cause cell injury in osteoarthritis.Objective: The aim of this study was to assess the impact of standardized rose-hip powder on mobility of the hip and knee joints, activities of daily living, quality of life, and pain in patients with osteoarthritis.Methods: Patients with a diagnosis of osteoarthritis of either the hip or knee, verified on radiography, participated in this randomized, placebo-controlled, double-blind study. Half of the patients were given five 0.5-g capsules of standardized rose-hip powder twice daily for 4 months, and the other half received identical placebo capsules twice daily for the same period. Mobility of the hip or knee was measured in both groups after the initial screening and again after 4 months of therapy.Results: One hundred patients (65 women, 35 men; mean [SD] age, 65.2 [11.1] years) were divided into 2 treatment groups of 50 patients each. Hip joint mobility improved significantly in the treatment group compared with the placebo group (P = 0.033). Similarly, pain decreased significantly in the treatment group compared with the placebo group (P = 0.035). Two patients (4%) from each group withdrew during the early stages of the trial for reasons not related to treatment.Conclusions: In this study population, standardized rose-hip powder reduced symptoms of osteoarthritis, as 64.6% of patients reported at least some reduction of pain while receiving treatment. Standardized rose-hip powder may improve hip flexion and reduce pain in patients with osteoarthritis.     

Dry powder aerosols of polyethylenimine (PEI)-based gene vectors mediate efficient gene delivery to the lung

Aerosol gene delivery holds great therapeutical potential for many inherited and acquired pulmonary diseases. The physical instability of aqueous suspensions of non-viral vector complexes is a major limitation for their successful application. In this study, we investigated dry powder aerosols as novel gene vector formulations for gene transfer in vitro and murine lungs in vivo. Lyophilization was used to produce dry powder cakes followed by powderization to produce dry powder aerosols. Different sugars, namely lactose, sucrose and trehalose, were tested as lyoprotectants for gene delivery complexes consisting of branched polyethylenimine 25 kDa and plasmid DNA. Biophysical particle characterization demonstrated that lyophilization and powderization in the presence of lyoprotectants were well tolerated. In vitro transfection efficiency remained unaffected by the choice of lyoprotectant and subsequent lyophilization and/or powderization. In vivo screening of powderized samples, by applying the powder with an insufflator, resulted in highest gene expression with lactose as lyoprotectant. Delivering a plasmid coding for murine erythropoietin together with lactose as lyoprotectant resulted in increased blood hematocrit values post application thereby demonstrating the potential of dry powder aerosol as a promising method for pulmonary gene delivery.
