Objective To investigate the incidence and risk factors of acute kidney injury (AKI) after cardiopulmonary bypass(CRB) in children with non cyanotic congenital heart disease. Methods A total of 150 children who underwent cardiopulmonary bypass operation from 2012 May to 2014 May were analyzed retrospectively. The patients were divided into two groups:AKI group (n=29) and non AKI group (n=121). Clinical data were collected and compared between two groups, including gender, age and baseline serum creatinine level. Multivariate Logistic regression analysis was used to evaluate the risk factors for AKI after operation. Results There was no death in the 150 cases. Comparison between groups, there were significant differences in age, history of heart failure and (or)pneumonia, baseline serum creatinine level, baseline uric acid, body mass, CPB) time, aortic clamping time, mechanical ventilation time, postoperative transfusion and hypotension. Multivariate Logistic regression analysis showed that age (≤1 years old), the history of pneumonia and (or) heart failure, CPB time (>40 min), aortic clamping time (>30 min) were the independent risk factors for AKI after operation. Conclusion It is important to choose the best age for surgery in children, actively prevent preoperative complications and shorten the CPB and aorta blocking time for preventing the occurrence of AKI.

BACKGROUND:Cholesterol is closely linked to the occurrence and progression of atherosclerosis. Current approaches to study celular cholesterol dynamics have their own limitations.
OBJECTIVE: To measure the cholesterol efflux rate of RAW 264.7 mouse macrophages by BODIPY-Cholesterol labeling and to explore the effects of extracelular cholesterol and lipopolysaccharide on the cholesterol efflux rate.
METHODS:RAW 264.7 cels were cultured in vitro with DMEM containing 10% fetal bovine serum, and labeled with BODIPY-Cholesterol for 1, 2, 4, 8 hours. Then, the cels were rinsed with serum-free DMEM and inoculated for 6, 12, 24, 48, 96 hours to optimize the labeling time and incubation time. We measured and compared the cholesterol efflux rates after cultured cels were treated with cholesterol, lipopolysaccharide, human sera with high cholesterol or human sera with normal cholesterol.
RESULTS AND CONCLUSION: The best labeling time for BODIPY-Cholesterol was 2-8 hours. Cholesterol efflux rates were gradualy decreased after the cels that were labeled for 2 hours were incubated with increasing concentrations of cholesterol (0.1, 0.5, 2.5 mmol/L,P< 0.01). Treating cels with lipopolysaccharide also decreased the cholesterol efflux rate (P < 0.05). Furthermore, the cholesterol efflux rate was decreased after cels were treated with human sera with high cholesterol (P< 0.05). These findings indicate that BODIPY-Cholesterol can be used to measure celular cholesterol efflux rate and to study the effects of extracelular cholesterol and lipopolysaccharide on the cholesterol efflux rate.

Objective To explore the changes of neutrophil elastase (NE) and surfactant protein A (SP-A) in acute lung injury(ALI) rats,and the effect of antioxidant. Methods Sixty healthy mature Wister rats were divided into 2 groups, the control group and treatment group. The rats in two groups all received peritoneal injection of E. coli to establish the ALI animal model. 30 minutes after injection of E. coli,the rats in treatment group were injected reduced glutathione from vena caudalis. The levels of NE in blood and expressions of SP-A in lung tissue were detected at 3,6 and 12 hours after injection of E. coli. Results ALI symptom appeared 3 hours after injection of E. coli in the control group, obvious after 6 hours, the rats vomi-ted pink secretion after 12 hours. Lung edema and bleeding were found by pathologic examination. No obvious symptom was found in treatment group after 3 hours, slight tachypnea after 6 hours, slight edema in pulmonary tissue after 12 hours. After administration of reduced glutathione,levels of NE at 3,6 and 12 hours in the treatment group were lower than those in the control group,and indicated statistical significance in 6 and 12 hours(P <0. 05) ;Levels of SP-A in 3,6 and 12 hours in the treatment group were higher than those in the control group, and indicated statistical significance in 3,6 and 12 hours (P < 0. 05). Conclusion Dysfunction of pulmonary surfactant is secondary in ALI, degradation of SP-A is the one of reasons, the application of reduced glutathione as antioxidant, could effectively suppress NE to decompose basosexine elastin of cells and destroy surface active protein, has protective effect on ALI.

Objective To explore the CT findings of mucoepidermoid carcinoma (MEC) of the tracheobronchial tree and improve the diagnostic accuracy. Methods The CT images, histopathological and clinical data in 24 patients with pathologically proved MEC of the tracheobroncbial tree were retrospectively analyzed. Results The clinical symptoms included cough, sputum, fever, wheezing, chest pain and hemoptysis. The patient was proved to be low-grade (n=19) and high-grade (n=5) MEC histopathologically. One lesion was located in trachea, 6 in main bronchus, 12 in lobar bronchus and 5 in segmental, subsegmental and distal bronchus. The tumor presented as no-invasive endotracheobronchial well-defined round-like nodule (n=13, locating in lobar and higher bronchus) and columnar sharp (n=3, locating in main bronchus), or intra-and-extraluminal well-defined round-like nodule or mass (n=6, locating in lobar and lower bronchus) and irregular mass with invasive pattern (n=2, high-grade type). The density of lesion was similar to the muscule and the calcification within lesion was showed in 4 patients on non-enhanced CT. The lesion had marked enhancement in 17 patients on enhanced CT. Obstructive changes were found in 20 patients. Conclusion MEC of the tracheobronchial tree is usually low-grade malignancy and locates in main and lobar bronchus with no-invasive well-defined airway mass, marked enhancement and calcification on CT.

[Objective] The present study aimed to determine the protective role of Melatonin (MT) against Acrylamide (AA)-induced testicular toxicity and the potential molecular mechanism.[Methods] The animals were randomly divided into three groups,the control group (n =12),the AA group (n =12) and the AA+MT group (n =12).The rats in the AA and AA + MT group were gavaged with AA at a dose of 15 mg/(kg · day) for 4 consecutive weeks.After 3 weeks of AA treatment,MT was intraperitoneally injected 30 minutes before AA treatment at 10 mg/(kg· day) for 1 week in the AA + MT rats.Subsequently,the mitochondrial membrane potential measurement,TUNEL assay,Western blot and electron microscopic techniques were applied in the present study.[Results] The results showed that AA could decrease the testis mitochondrial membrane potential (P < 0.05) which could be recovered by MT (P < 0.05).Moreover,MT induced down-regulation of Bax expression and up-regulation of Bcl-2 expression in the testis,compared with AA rats.The amelioration of testicular apoptosis was further confirmed by the TUNEL labeling.Western blot results suggested that the decreased ratios of Bcl-2/Bax and Bcl-xL/Bak in the AA group (both P < 0.05) could be recovered by MT treatment (both P < 0.05).The levels of Cyt-c,Casp-3,p53 and NF-κB in AA group were markedly elevated compared with the control (all P < 0.05),and reduced in MT treatment group (all P < 0.05).MT could relieve abnormal mitochondrial structures in the seminiferous tubule in the electron microscopic level.[Conclusion] MT may exert productive effect through its anti-apoptotic properties associated with mitochondria.

OBJECTIVETo study the therapeutic mechanism of Zhizhu Pill (ZP) for treating functional dyspepsia (FD) rats.
METHODSTotally 30 ten-day-old male rats were randomly divided into the normal control group (n =10) and the model group (n = 20). The FD rat model was induced using gastric administration of 0.1% iodoacetamide (IA) combined tail clamping. The model was evaluated when rats were 8-week old. Successfully modeled rats were randomly divided into the model group (n = 10) and the ZP group (n = 10). Rats in the normal group and the model group were administered with normal saline by gastrogavage, while those in the ZP group were administered with ZP Decoction (2 mL/100 g) by gastrogavage. All medication lasted for 7 successive days. The contractile activity in in vitro longitudinal gastric muscle was recorded using Power Lab biological signal collecting system. The expression of growth hormone secretagogue receptor (GHSR) in stomach of FD rats was detected using Western blot and immunohistochemistry (IHC).
RESULTSCompared with the normal group, average frequencies of gastric contraction and changing rates of amplitude obviously decreased in the model group (P < 0.05). Results of Western blot and IHC showed that the expression of GHSR decreased in the model group (P < 0.01). Compared with the model group, average frequencies of gastric contraction and changing rates of amplitude obviously increased in the ZP group (P < 0.05). Results of Western blot and IHC showed that the expression of GHSR increased in the ZP group (P < 0.01).
CONCLUSIONZP could promote the gastric motility in FD rats induced by gastric administration of IA combined tail clamping, and its mechanism might be related to up-regulating GHSR protein level.

OBJECTIVETo summarize the clinicopathological characteristics and prognostic factors of primary pulmonary mucinous adenocarcinoma (PPMA).
METHODSThe clinicopathological manifestations and radiological appearances of 57 PPMA patients surgically treated and pathologically proved between Jan. 2001 and Dec. 2006 were retrospectively analyzed. The cumulated survival rate was calculated by life table method.
RESULTSThere were no specific clinical manifestations in PPMA patients, while the tumors were radiologically pleomorphologic. Of these 57 patients, 5 were in stage Ia, 20 in stage Ib, 1 in stage IIb, 11 in stage IIIa, 6 in stage IIIb and 14 in stage IV. The cumulated 1-, 3- and 5-year survivals of those with complete resection were 88.0%, 55.0% and 55.0%, respectively.
CONCLUSIONThe final correct diagnosis of primary pulmonary mucinous adenocarcinoma should be made by pathology. Though the treatment is not different, the prognosis of the patients with primary pulmonary mucinous adenocarcinoma is better than that of those with adenocarcinoma.
