金水宝片联合依诺肝素对维持性血液透析患者血脂代谢的影响

目的：探究金水宝片联合依诺肝素对维持性血液透析患者血脂代谢的影响。方法：选取2018年12月至2019年3月马鞍山十七冶医院血液净化中心进行透析的患者154例作为研究对象，根据用药不同分为对照组和观察组,每组77例。对照组常规应用依诺肝素抗凝，观察组在对照组抗凝基础上加用金水宝片，各组均干预3个月，比较2组患者血脂变化及持续血液透析并发症发生情况。结果：治疗后，观察组患者三酰甘油、总胆固醇及低密度脂蛋白胆固醇水平下降，高密度脂蛋白胆固醇升高，与治疗前比较差异均有统计学意义（P<0.05），与对照组治疗后比较，差异有统计学意义（P<0.05）；观察组总并发症发生率明显低于对照组，2组比较差异有统计学意义（P<0.05）；2组患者维持性血液透析不良反应发生率均较低，组间比较差异无统计学意义（P>0.05）。结论：金水宝片联合依诺肝素有助于改善维持性血液透析患者血脂代谢水平，降低维持性血液透析相关并发症，值得临床推广应用。     

妇科恶性肿瘤术后骨质疏松症的防治

为探讨妇科恶性肿瘤术后骨质疏松症的预防措施,采用补充紫竹爱维和乐力胶囊来预防骨质疏松的发生,分别与未服药的妇科恶性肿瘤及良性肿瘤术后作对照,并对其对骨代谢指标血清骨性碱性磷酸酶(BALP)及血清抗酒石酸酸性磷酸酶(TRAP)的影响进行了临床观察.结果发现恶性肿瘤术后较良性肿瘤术后患者的BALP降低,TRAP增高,服用紫竹爱维与乐力胶囊的患者TRAP均低于未服药的恶性肿瘤术后患者,P＜0.05,均有显著性差异.表明妇科恶性肿瘤术后患者较良性肿瘤更易患骨质疏松症,服用紫竹爱维与乐力胶囊均能有效防治骨质疏松症,前者效果更佳,但应掌握性激素补充治疗(HRT)的应用指征.

Optimization of a formulation for direct compression using a simplex lattice design

In this paper it is demonstrated how the optimum composition of a mixture for direct compression consisting of -lactose monohydrate, roller-dried -lactose and microcrystalline cellulose can be found using a systematic optimization technique. The experiments were chosen according to a simplex lattice design. The results of these experiments were used to fit a mathematical model, which then can predict the properties of all possible mixture compositions and enables a graphic representation of these properties in the form of contour plots. At a level of 4% the effect of three disintegrants (sodium starch glycolate, croscarmellose sodium and crospovidone) on the properties of the tablets compressed from these filler-binders, was evaluated by superimposing the contour plots of the different tablet responses. It was found that all the disintegrants used were effective in this combination of filler-binders. In order to evaluate drug dissolution rate an extra experiment with crospovidone as the disintegrant was performed, in which oxazepam was used as a test drug.

Preparation and evaluation of sodium diclofenac controlled-release tablets

The dissolution behaviour of a direct compression compact prepared with sodium diclofenac and dibasic calcium phosphate (DCP) in different weight ratios with or without Biosoluble polymer^® (acrylic-based resin) was investigated in distilled water and in a medium with changing pH. The results indicate that the amount of sodium diclofenac released from the compact was dependent on the amount of drug and DCP used in the compact, and was also controlled by the amount of Biosoluble polymer^® added. A chemical reaction forming diclofenac acid might occur on the surface of the sodium diclofenac compact during exposure to the acidic medium, which was confirmed by diffuse-reflectance spectroscopy. The tablet with a 12 weight ratio of sodium diclofenac to DCP exhibited a sustained-release behaviour, similar to commercial sustained-release products (Voltaren SR-100^® and Grofenac Retard^®), but a lower release rate was found as compared to the commercial products. The dissolution behaviour of the study tablet and the commercial products was found to be dependent on the dissolution medium and the rotating speeds. Glass beads were added to the dissolution assembly to simulate the influence of food, and the enhanced friction between tablet and glass beads might result in a higher dissolution rate of the tablet and the commercial products.     

Administration of obidoxime tablets to man

Twenty-four male volunteers were given obidoxime tablets in quantities ranging from 1.84–3.58 g in a single dose, or 7.36 g divided into 4 equal doses. With the lowest dose, average peak plasma level of the drug was 1.9 g/ml and after the highest single dose it was 5.6 g/ml, both attained 1.5 h after administration. In the multiple-dosed individuals, plasma levels of the oxime increased gradually following each additional dose, reaching a peak of 3.5 g/ml after the last dose.Thirteen individuals complained of one or more of the following side effects: pallor, nausea, pyrosis, headache, generalized weakness, sore throat, and paresthesia of the face muscles.Activities of blood cholinesterase, glutamic oxalacetic transaminase, glutamic pyruvic transaminase, as well as hematocrit values, heart rate, and blood pressure were not affected.It is postulated that due to the undesirable side effects, the general use of obidoxime tablets should not be recommended. However, prophylactic oral treatment with obidoxime could be considered for persons at high risk of organophosphate poisoning or when parenteral administration might not be feasible.
