Objective:To study the efficacy of single itraconazole and combination with interferon-? against Candida albicans infection.Methods:Murine models of systemic candida albicans infection were established, and treated with different concentrations of itraconazol alone and combination with INF-?. Then the concentrations of colonyforming units(cfu) and histolo gical sections were observed to evaluate the emcacy. Results:The combination of 105U INF-? and itraconazole at the dosage of 10mg/kg showed better effect against Candida albicans than the combination of itraconazole at the dosage of 50mg/kg with 105U INF-?. Conclusion:The combination of itraconazole at a low dose with INF-? shows a good effect against Candida albicans.The single use of itraconazole at a high dose is also anti-infection.

Objective To observe the clinical efficacy of filiform fire-needle therapy plus mild moxibustion in treating flat warts.Method Ninety patients with flat warts were randomized into group A, group B and group C, 30 cases in each group. Group A was intervened by filiform fire-needle therapy plus mild moxibustion, group B was intervened by filiform fire-needle therapy alone and group C by mild moxibustion alone. The three groups all received treatment 3 times a week, 2 weeks as a treatment course, for 2 courses in total. The clinical efficacies of the three groups were compared.Result In group A, 12 subjects were recovered, 13 showed improved, and 5 cases failed; in group B, 7 subjects were recovered, 12 showed improved, and 11 failed; in group C, 5 cases showed recovered, 10 were improved, and 15 failed. The total effective rates were respectively 83.3% in group A, 63.3% in group B, and 50.0% in group C, and the total effective rate in group A was significantly higher than that in group B and C (P<0.05). Conclusion Filiform fire-needle therapy plus mild moxibustion can significantly help the skin rashes subside in treating flat warts, and the therapeutic efficacy is obviously superior to that of either of the two methods used alone.

AIM: To observe the efficacy, feasibility and safety of endovascular stent-grafts in treating aortic dissection.METHODS: Six patients with aortic dissecting aneurysm (3 males and 3 females, aged 32-67 years, average of 50 years old) were selected from Department of Cardiology, First Affiliated Hospital of Gannan Medical College between March 2005 and March 2006. They were diagnosed by transthoracic magnetic resonance imaging (MRI) and aortic angiography, and as type Ⅲ aortic dissecting aneurysm according to Debakey typing. The tumor diameter was ranged from 3.2 to 4.3 cm. The informed consent was obtained from all patients. Two weeks after the onset, the blood pressure was control between 90-110 and 60-70 mm Hg and heart rate at 60-65 times/min, then the straight circular and bifurcated stents, the product of Yuhengjia Company, composed of single naked membrane, straight circular and bifurcated stents made of nickel-titanium memory alloy, and cover of domestic artificial blood vessel were implanted with the patients generally anesthetized. The aortic dissection and general condition of patients after operation were observed with angiography, and the patient recovery condition was examined by spiral CT at postoperative months 3 and 12.RESULTS: All 6 cases were involved in the result analysis.①The diameters of stents for the patients were appropriate. The angiography showed that the thoracic aortic dissection in 4 cases disappeared, and thrombogenesis was found in false lumen; the thoracic aortic dissections in 2 cases disappeared, however, a little contrast agent was found in false lumen, but the blood flow was very slow. The general condition of all patients was good with stable vital signs, all patients discharged after 7-10 days.②CT results at 3 month after operation suggested that the original false lumen significantly contracted, and the true lumen restored to normal level. In case 3, there was mural thrombus in the distal stent that connected with stent vessel wall, and the thrombus hyperplasia was not obvious during follow up. At 12 months after operation, there was no distinct alteration in the stent location and appearance, and the life quality of patients was significantly improved.CONCLUSION: Endovascular stent-grafts are effective and safe in treating aortic dissection.

Objective To study the effects of insulin resistance on the occurance of hypertension in uremia. Methods With use of the oral glucose tolerance test (OGTT) and the insulin release test (IRT) , insulin glycoregulatory activity, including insulin sensitivity index (ISI) , glucose uptake rate (M) and the total areas under the glucose and insulin curves during OGTTs (AUCG, AUCINS) were investigated in 29 hypertensive (CRF-H) and 21 normotensive (CRF-NH) urernic patients and 12 healthy controls (C), and their plasma renin activity (PRA), angiotensin Ⅱ (AT Ⅱ) levels were investigated too. Results (1) Uremic patients had significantly higher blood glucose and serum insulin levels after glucose load, much higher AUCG and AUCINS values and significantly lower ISI and M values than the controls, compared with the CRF-NH patients, CRF-H patients had significantly higher blood glucose levels at 30', 60', 120', and higher serum insulin levels at 120' during OGTTS, significantly higher AUCG and AUCINS values, significantly lower ISI and M values and significantly increased incidences of insulin resistance and glucose intolerance; (2) Insulin resistant patients had more frequency and severe hypertension than the non-insulin resistant ones; simple regression showed that arterial blood pressure (SBP, DBF, MBP) had significant negative correlation with ISI and M, significant positive correlation with AUCG and AUCINS; (3) The levels of PRA, ATⅡbetween two CRT groups were not different; (4) Multiple linear regression showed that AUCG and AUCINS had significant positive correlation with MBP independent of age、 sex、 obesity、 the degree of real failure and plasma renin-angiotensin activity. Conclusion Insulin resistance 、 hyperinsulinemia and glucose intolerance or hyperglycemia may be one of the important mechanisms of uremic hypertension.
