Objective To explore the underlying mechanisms and effects of pitavastatin on hepatic inflammation and injury induced by ischemia reperfusion(IR) in rats. Methods Male Sprague-Dawley rats were randomly divided into 4 groups:a sham-operation group, an ischemia?reperfusion (IR) group, a pitavastatin therapy group and a pitavastatin-ZnPP group. Eight hours post reperfusion, blood was collected and hepatic tissue was isolated. Then, we detected the levels of ALT and AST in the serum as well as myeloperoxidase (MPO) in the liver. Additionally, realtime-PCR was performed to assay HO-1, iNOS and ICAM-1 expression. Results IR induced dramatic hepatic inflammation and injury in rats. Compared with the IR group, pitavastatin treatment lowered the levels of ALT, AST and MPO, suppressed the expression of two pro-inflammatory genes such as iNOS and ICAM-1, and improved hepatic lesions. Nevertheless, an HO inhibitor, ZnPP, reversed the protective effects of pitavastatin on IR injury. Furthermore, HO-1 expression was induced by IR and further promoted by statin treatment. Conclusion Mediated by promoted HO-1 expression, pitavastatin plays a protective role for hepatic inflammation and IR injury in rats.

Based on institutional and personal experience in more than 1 000 patients treated by PCNL, we reviewed the literature (Pubmed search) focusing on technique, type, and incidence of complications of the procedure. Complications during or after PCNL may be present with an overall complication rate of up to 83%, including extravasation (7.2%), transfusion (11.2%–17.5%), and fever (21.0%–32.1%), whereas major complications, such as septicaemia (0.3%–4.7%) and colonic (0.2%–0.8%) or pleural injury (0–3.1%) were rare. Comorbidity (i.e., renal insufficiency, diabetes, gross obesity, pulmonary disease) increased the risk of complications.Most complications (i.e., bleeding, extravasation, fever) could be managed conservatively or minimally invasively (i.e., pleural drain, superselective renal embolisation) if recognised early. The most important consideration for achieving consistently successful outcomes in PCNL with minimal major complications were the correct selection of patients, a well-standardised technique and postoperative follow-up.

Abstrac: Objeetive To study the effects of simvastin on the characterization of plaque and vascular elasticity in rabbits with atherosclerosis. Methods 30 New Zealand rabbits were randomly divided into three groups. The rabbits in control group were given basic food, and the rabbits in model group were given aortic endothelium balloon injury and high lipid diet, and simvastin were given to the treatment group. After 10 weeks, the ratio of thickness of fibrous cap and the lipid core areas were obtained by pathological observation, and vascular elasticity were estimated with echo-tracking. Results The rabbits in model group had the less weak thickness of fibrous cap and the greater areas of lipid core than the treatment group. And the vascular elasticity in simvastin treatment group were better than that of the model group(P<0.05). The ratio of thickness of fibrous cap and the lipid core areas were negativly related to pressure-strain elasticity modulus (Eρ) and the stiffness parameter (β). conclusion Simvastin participate in the everlasting atherosclerosis vascular remodeling, with inhibiting inflammation, improving vascular endothelial function and changing the characterization of plaque.

Objective To study the effects of dexrazoxane in preventing paclitaxel-induced cardiotoxicity in rat models and its mechanism. Methods 64 Wistar rats were randomly divided into four groups: Control group, paclitaxel group, paclitaxel + small dose of dexrazoxane group, paclitaxel + large dose of dexrazoxane group. The cardiotoxicity was assessed by measuring serum cardiac troponinl (cTnI), brain natriuretic peptide (BNP), superoxide dismutase (SOD) and malondialdehyde (MDA) at the end of the 8th and 16th weeks. Results At the end of the 8th weeks the differences for cTnI, BNP, SOD, MDA, pathological performance between groups was not statistically significant (P>0.05). At the end of the 16th weeks paclitaxel increased serum cTnI and BNP (P<0.05). The dexrazoxane acceleration the increasing cTnI and BNP (P<0.05). Dexrazoxane + paclitaxel reduce SOD, increased MDA, the difference was statistically significant (P<0.05). The comparison between the different doses of dexrazoxane group was not statistically significant (P>0.05). conclusion The dexrazoxane increase paclitaxel-induced cardiotoxicity through reducing free radical scavenging enzyme activity, resulting in excessive lipid peroxidation products.
