Objective To determine the effects of trimetazidine (TMZ) on pathology and energy metabolism of myocardium in chronic renal failure(CRF) rats.Methods CRF models were built in Sprague-Dawley (SD) rats with 5/6 subtotal nephrectomy, and animals were randomyly divided into sham group, control group and three groups treated with different doses of TMZ (3 mg/kg,6 mg/kg or 9 mg/kg).TMZ was intragastrically administrated to CRF rats for 17 weeks, while physiologicalsalinewasusedascontrol. Transthoracicechocardiographywasperformedand myocardial morphosis was observed.Left ventricular weight/body weight(LVW/BW) and heart weight/body weight (HW/BW) were measured, and heart rate, and mean arterial pressure (MAP)were detected at the end of the study, while several parameters were detected, including urea nitrogen (BUN), creatinine(Scr), triphosaden(ATP), adenosine diphosphate(ADP), superoxide dismutase (SOD), malondialdehyde (MDA), interleukin 6 (IL-6) and tumor necrosis factor α (TNF-α).Results (l)Left ventricle end-systolic dimensions, anterior wall end-diastolic and end-systolic thicknesses, and posterior wall end-diastolic thickness were significantly lower in rats treated with either medium dose or high dose of TMZ, as compared with control group(P<0.05).(2)LVW/BW and HW/BW in rats treated with either medium dose or high dose of TMZ were significantly lower than those in control group(P<0.05). (3)Various pathological changes were observed in control group, such as irregular arrangement and hypertrophy of the cardiomyocytes, myocardial fibrosis,mitochondrial swelling, focal muscle fiber dissolution, etc.However, all these pathological changes were apparently ameliorated in TMZ-treated groups, while the beneficial effects of TMZ therapy were dose-dependent. (4)No difference was observed in heart rate among all the groups.Although no difference existed in all the CRF rats, concerning on the systolic/diastolic blood pressure and mean arterial pressure (P>0.05), these parameters were elevated in CRF rats, as compared with sham-operated group(P<0.01). (5)ATP and ADP in TMZ-treated rats were significantly higher as compared with control(P<0.05), moreover, medium dose and high dose of TMZ were superior to low dose (P<0.05).(6)SOD was significantly increased in TMZ-treated rats (P<0.05), while IL-6,TNF-α and MDA were significantly decreased in medium dose and high dose of TMZ, as compared with control(P<0.05).Conclusion TMZ may prevent myocardial fibrosis and left ventricular hypertrophy in chronic renal failure via ameliorating myocardial energy metabolism and alleviating inflammatory reaction and oxidative stress.

Objective To evaluate the role of renal cell apoptosis in acute kidney injury (AKI) induced by sepsis in mice. Methods Forty-five male C57BL/6 mice were randomly assigned into 3 groups ( n = 15 each):sham operation group (group S), cecum ligation and puncture group (group CLP) and CLP + caspase-3 inhibitor Ac-DEVD-CHO group (group CI). Intra-abdominal infection was induced by CLP. Ac-DEVD-CHO 4 μg/g was infused subcutaneously 30 min before CLP in group CI. Five mice in each group were sacrificed after collection of blood samples at 6, 12 and 24 h after CLP. The levels of serum blood urea nitrogen (BUN) and creatinine (Cr)were detected. The apoptosis rate and expression of caspase-3 protein and caspase-3 mRNA were determined.Pathological changes in renal tissues were observed with light microscope. Results The serum BUN and Cr concentratiors, apoptosis rate and expression of caspase-3 mRNA and caspase-3 protein were significantly higher in group CLP than in group S, but lower in group CI than in group CLP ( P < 0.05). Light microscopic examination showed that the pathologic changes induced by Ac-DEVD-CHO were less severe in group CI than in group CLP.Conclusion The renal cell apoptosis is one of the mechanism of AKI induced by sepsis.

OBJECTIVETo explore the value of MSCT in the preoperative TNM staging and the longest tumor diameter measurement (RESIST standard) of gastric cancer.
METHODSClinical data of 153 consecutive patients with biopsy-confirmed gastric carcinoma who were preoperatively evaluated with enhanced MSCT scanning in our hospital from January 2012 to March 2013 were retrospectively analyzed. Consistency comparison was performed between preoperative TNM staging and the longest tumor diameter measurement and histopathological findings.
RESULTST-staging consistency of Kappa value was 0.566, and accuracy was 71.2%. N-staging consistency of Kappa value was 0.284, and accuracy was 47.7%. The Kappa value of M-staging consistency was 0.893, and accuracy was 98.7%. The overall accuracy of TNM staging consistency was 66.7% (102/153) with a Kappa value of 0.573. Effective measurement of the longest cancer diameter was carried out in 53 patients. There was no significant difference between preoperative longest tumor diameter acquired by MSCT and postoperative tumor measurement [(68.8 ± 40.6) mm vs. (64.2 ± 36.2) mm, P=0.969].
CONCLUSIONMSCT is accurate in preoperative TNM staging and longest tumor diameter measurement of gastric cancer compared with postoperative pathological examination, and can provide reliable evidence for preoperative staging and neoadjuvant therapy evaluation of gastric cancer, but it is unfavorable to evaluate the lymph node metastasis.
