Influence of continuity care on how to deal with medical waste among domestic patients of insulin injections / 中国实用护理杂志

Objective To explore the influence of continuity care model on how to deal with medical waste of insulin injections among domestic patients Methods Consecutive diabetes patients using the home insulin injections were recruited as the the members of our Diabetes Education Classfrom September 2014 to March 2015. The home medical waste disposal was brought into the content of diabetes education;problems were intervened through the continuity care model. Using the questionnaire survey to investigate the cognitive and disposal of patients on medical waste, to compare the difference of results of questionnaire before and after the intervention. Results The cognitive rate of medical waste after intervention was 97.70%(212/217),while the cognitive rate before intervention was 3.69%(8/217), the difference was significant (χ2=383.63,P<0.01). Disposal of diabetes patients using the home insulin injections had improved after the continuity care, the rate of dealing with medical waste according to specification after the intervention was 91.24% (198/217),while the rate before the intervention was 3.23%(7/217), the difference was significant (χ2=337.26,P<0.01). Conclusions The continuity care model standardized the behavior of patients for disposal of medical waste, reduced the environment pollution of medical waste and decreased the spread of disease.

General Pharmacological Study of Aloe’s Whole-leaf Freeze-dried Powder / 中国中医药信息杂志

Objective To study the general pharmacological effects of Aloe's whole-leaf freeze-dried powder (AWFD), and observe its influence on cardiovascular system, nervous system and respiratory system of laboratory animals, so as to offer an experimental basis for clinical application. Methods Forty-eight mice were randomized into blank control group, high dosage group, medium dosage group and low dosage group of AWFD (12 mice for each group). AWFD high, medium and low dosage groups were treated by intragastric at the dose of 12.20, 3.90, 0.65 g/(kg?d), blank control group was treated by equal volume of sterilized distilled water. After three days, general behavior, spontaneous activity, coordinated movement, sleep situation induced by sodium pentobarbital in subthreshold dose and suprathreshold dose were observed. Twenty-four beagle were randomized into blank control group, high dosage group, medium dosage group and low dosage group of AWFD (6 beagles for each group). AWFD high, medium and low dosage groups were treated by duodenum at the dose of 6.10, 3.41, 0.71 g/(kg?d), blank control group was treated by equal volume of sterilized distilled water. The influence on blood pressure, heart rate, electrocardiogram, breathing flow and frequency in anesthetic dogs were observed. Results Three dosages of AWFD had no obvious influence on spontaneous activity and coordinated movement in mice, and had no evidently influence on sleep number and duration, but the high dosage group of AWFD had influence on sleep latency (P<0.01). AWFD had no impact on blood pressure, heart rate, electrocardiogram, breathing flow and frequency in anesthetic dogs. Conclusion AWFD has no evident effects on cardiovascular system and respiratory system in laboratory animal, however, the impact on the central nervous system remains to be further verified.

Antioxidative Dosage-effect Relationship of Grape Seed Proanthocyanidin Extract / 中国中医药信息杂志

Objective To observe the antioxidative dosage-effect relationship of grape seed proanthocyanidin extract (GSPE). Methods The mice were randomly divided into seven groups:blank group, model group, 5 mg/kg GSPE group, 15 mg/kg GSPE group, 45 mg/kg GSPE group, 135 mg/kg GSPE group and 405 mg/kg GSPE group. The mice in blank group were dealt with saline solution by intraperitoneal injection, the others were dealt with D-galactose (120 mg/kg) by intraperitoneal injection for seven weeks to make oxidative damage model. Meanwhile, the mice were given corresponding dose of the drug. Subsequently the level of malondialdehyde (MDA) and activity of superoxide dismutase (SOD) in the serum were measured to observe the antioxidative dosage-effect relationship of GSPE. Results The 45, 135, 405 mg/kg GSPE group reduced the MDA level, and the 15, 45, 135, 405 mg/kg GSPE group increased the SOD activity. Conclusion GSPE has significant antioxidant activity on mice dealt with D-galactose above the dose of 15 mg/kg, suggesting that the clinical use of GSPE should guarantee a certain dose to play a good antioxidant effect.

Detoxication experimental study on different compatibility proportion of Aconiti Lateralis Radix Praeparata and glycyrrhizae radix et rhizoma / 中国中药杂志

<p><b>OBJECTIVE</b>Through the paired comparison on the toxicity effect of Aconiti Lateralis Radix Praeparata of different compatibility proportion of Aconiti Lateralis Radix Praeparata and Glycyrrhizae Radix et Rhizoma, to observe the detoxication effect of Glycyrrhizae Radix et Rhizoma to Aconiti Lateralis Radix Praeparata.</p><p><b>METHOD</b>Paired comparison on the mouse acute toxicity of Aconiti Lateralis Radix Praeparata and Aconiti Lateralis Radix Praeparata with different compatibility proportion of Glycyrrhizae Radix et Rhizoma, to assay the LD50. Paired comparison on the rat heart toxicity of Aconiti Lateralis Radix Praeparata and Aconiti Lateralis Radix Praeparata with different compatibility proportion of Glycyrrhizae Radix et Rhizoma, to assay the TD50. We dilute medicated serum of Aconiti Lateralis Radix Praeparata, Aconiti Lateralis Radix Praeparata plus Glycyrrhizae Radix et Rhizoma (3:1), Aconiti Lateralis Radix Praeparata plus Glycyrrhizae Radix et Rhizoma (1: 1) into 5%, 10%, 20% solution with serum free DMEM, to survey the effect of different concentration of medicated serum to the pulsing rhythm of myocardial cell of original generation newborn rat, cell surviva rate and content of LDH in myocardial cells.</p><p><b>RESULT</b>LD50 and TD50 of Aconiti Lateralis Radix Praeparata can be increased after adding Glycyrrhizae Radix et Rhizoma Compared to the blank serum, medicated serum with Aconiti Lateralis Radix Praeparata can obviously increased the pulse rhythm of myocardial cell and the content of LDH (P < 0.05). The medicated serum with Aconiti Lateralis Radix Praeparata added different proportion of Glycyrrhizae Radix et Rhizoma can reduce the acceleration of myocardial cell's rhythm, which is induced by Aconiti Lateralis Radix Praeparata, and can reduce the content of LDH. With the increased ratio of Glycyrrhizae Radix et Rhizoma, the effect is stronger. But for the serum with different concerntration of Aconiti Lateralis Radix Praeparata or Aconiti Lateralis Radix Praeparata added Glycyrrhizae Radix et Rhizoma, there is no obvious effect to the cell survival.</p><p><b>CONCLUSION</b>Glycyrrhizae Radix et Rhizoma has the detoxication effect through increasing the ultimatetotaldosage of Aconiti Lateralis Radix Praeparata. The detoxication effect of Glycyrrhizae Radix et Rhizoma to Aconiti Lateralis Radix Praeparata is through restraining the increased rhythm of myocardial cell and protecting the myocardial cell.</p>
