OBJECTIVE:
To evaluate the effect of patient education on patients with allergic rhinitis (AR).
METHOD:
From January 2009 to December 2013, 100 cases of allergic rhinitis were treated. The patients were randomly divided into experimental group or control group by Stochastic tables law,50 patients in control group accepted only drug treatment, 50 patients in experimental group accepted both drug treatment and patient education. The difference in compliance with treatment, treatment effect, incidence of adverse drug reactions and complications, average costs and times of treatment between two groups were evaluated by the rhinoconjunctivitis quality of life questionnaire (RQLQ) score. The independent sample t-test and χ2 test were used for statistical analysis.
RESULT:
The patients of experimental group showed more positive attitude to treatment compared to the patients of control group (P < 0.01). The average scores of each classification and overall symptoms after treatment in experimental group were lower than those in control group (P < 0.05). The incidence of adverse drug reactions (nose-bleed, dry nose,nasal mucosa ulcer)and complications in patients with AR (asthma, chronic cough, secretory otitis media) in experimental group was lower than that in control group, with statistically differences (P < 0.05). The average times of treatment and costs of diagnosis and treatment(calculation of budesonide nasal spray)in experimental group were significantly lower than those in control group (P < 0.01). The total score for RQLQ and the scores of seven dimensions in experimental group were lower than those in control group (P < 0.05).
CONCLUSIONS
Patient education can help the patients with AR to cooperate actively with treatment, to reduce the incidence of adverse drug reactions and AR complications, and to save medical costs and improve the quality of life.

Aim To study the effects of ganoderma lu-cidum polysaccharides and metformin on myocardial fi-brosis of type 2 diabetic rats and its mechanism. Methods SD rats were fed with high fat diet for 4 weeks, and then were injected with streptozotocin (30mg·kg-1 ) to replicate type 2 diabetic model. The diabetic rats were randomized into normal control group,diabetes group, ganoderma lucidum polysaccha-rides group ( 600 mg · kg-1 ) , metformin group ( 600 mg·kg-1 ) , and combination group( ganoderma lucid-um polysaccharides 300 mg·kg-1 +metformin 300 mg ·kg-1 ) . After 12 weeks’ treatment,the levels of fast-ing serum glucose were determined and the extent of myocardial fibrosis was observed by Picro-sirius red staining. The contents of AGEs in serum were deter-mined by fluorescence spectrophotometer. The activities of CAT and GSH-Px in myocardium were detected. Im-munohistochemical method and Western blot were used to detect myocardial tissue AGEs and CTGF protein ex-pression. Results Combination group could repress patho-proceeding of myocardial fibrosis efficiently, im-prove the activity of CAT and GSH-Px in myocardium and lower the concentration of AGEs in serum, as well as reduce the expression of AGEs and CTGF in myo-cardium. Conclusions Ganoderma lucidum polysac-charides and metformin could prevent myocardial fibro-sis. The possible mechanism may be related to repress-ing oxidative stress of myocardium, lowering serum AGEs and down regulating AGEs and CTGF of myocar-dium.

Aim To investigate the effects and mecha of ganoderma lucidum polysaccharides and metformin on pathological changes of thoracic aorta in diabetic ratsandthemechanisms.Methods SDratswerefed with high fat diet for 4 weeks and injected with strepto-zotocin ( 30 mg · kg-1 ) to replicate type 2 diabetic model. The diabetic rats were randomly into diabetes group, ganoderma lucidum polysaccharides group ( 600 mg·kg-1 ) ,metformin group(600 mg·kg-1 ) ,combi-nation group ( ganoderma lucidum polysaccharides 300 mg· kg-1 + metformin 300 mg · kg-1 ) and normal control group. After 12 weeksˊ treatment, the levels of fasting serum glucose, the activity of catalase(CAT), glutathione peroxidase ( GSH-Px ) , total cholesterol (TC)and triglyceride(TG) in serum were detected. Pathological changes of thoracic aorta were observed by HE staining. Immunohistochemy and Western blot were used to detect thoracic aorta VEGF protein expression. Results Combination group could lower fasting serum glucose and blood fat significantly, meanwhile the ac-tivity of CAT and GSH-Px in serum was improved. The expression of VEGF in thoracic aorta was repressed. The result of HE staining suggested that the lipid de-posits in aortic endothelium in combination group were lessthanthoseinthemodelgroup.Conclusions Ga-noderma lucidum polysaccharides combined with met-formin has an obvious prevention on pathological chan-ges of thoracic aorta in diabetic rats. The possible mechanism may be related to repressing oxidative stress of thoracic aorta, regulating the dyslipidemia, and the down regulation of the expression of VEGF in thoracic aorta.

Objective By using percutaneous endovascular microcatheter technique to establish an animal model of coronary microembolization in mini-swine which is suitable for long-term observation.Methods Coronary microembolization was established in 10 mini-swine by infusing 15 × 10~4 microspheres (φ45μm) selectively into the left anterior descending artery (n = 10). Coronary flow reserve (CFR) was measured by Doppler wire and left ventricular eject fraction (EF) was assessed by echocardiography.Hematoxylin and eosin (HE) staining and nitroblue tetrazolium (NBT) dye were used to demonstrate the presence of microembolization after the procedure of coronary microembolization. The ultra-structures of cardiomyocyte were observed by transmission electron microscopy (TEM). Before sacrifice, the CFR measurement and coronary angiography were performed again in survival animals. Results The coronary microvascular integrity (CFR < 2.0) and left ventricular function (EF < 50% ) were damaged by coronary microembolization. One month after the procedure, all the 10 animals survived and were able to receive the angiography and CFR measurement again. HE staining and NBT dye could demonstrate the presence of microembolization. The edema and fibrosis of cardiomyocytes could be revealed with TEM. Conclusion The animal model of coronary microembolization can be established in mini-swine by using percutaneous endovascular microcatheter technique. The model is suitable for long-term observation, the preparation is technically-simple and minimally-invasive with very low mortality. Therefore, this kind of animal model is an ideal experimental form for studying the mechanism of coronary microembolization.

Objective To evaluate the therapeutic effect of 32P application and interventional therapy in skin hemangioma, and to sum up the role of nursing in the process of the treatment. Methods 734 cases of skin hemangiorna were involved in the study. Personalized treatment strategy and nursing measures were implemented according to different kinds of skin hernangioma, 32p application device was made with the dose of 1 Gy per square centimeter every day, and the total dose of interventional therapy was from 6.8μCi to 10.0μCi per square centimeter according to the site of lesions and the patients' age. The treatment interva] was about one and a haft month or two months. The specific nursing measures were as follows: effective communication should be undertaken to remove the concerns of patients before therapy. Meanwhile, the lesions should be taken a picture by a digital camera before and after therapy. Thus, the effect could be evaluated objectively. In addition, the follow-up by telephone also was done in the study. Results the cure rate and the effective rate of 32P in the treatment of skin hemangioma were 78.88% and 94.14% respectively.The treatment effect was the best in hemangioma simplex among different kinds of skin hemangioma. The treatment effect had a negative correlation with the age of the patients. Selective nursing reduced incidence of complication. Conclusions There's a satisfactory effect of 32p application and interventional therapy in the treatment of skin hemangioma. Meanwhile, nursing plays an important role in the treatment.
