OBJECTIVE:To explore the effect of tiopronin on the expression of cytochrome P4502E1(CYP2E1)in liver of rats with alcoholic fatty liver.METHODS:30 Wistar rats were randomly divided into 3 groups:group A(blank control group),group B(model group)and group C(tiopronin group).Group B and group C were given 50% alcohol intragastrically to establish alcoholic fatty liver model,while group C were intervened with tiopronin(0.15 g?kg-1?d-1 administered at 1 hour after alcohol administration)for 5 consecutive weeks.Then all the rats were sacrificed with AST and ALT levels in serum determined.The CYP2E1 expression was detected by RT-PCR;and the pathologic changes of the liver tissues were observed.RESULTS:In group B compared with group A,serum levels of AST,ALT and CYP2E1 expression were significantly higher(P

Objective To observe the protective effect of aprotinin on the cerebral ischemia-reperfusion injury. Methods Rat model of cerebral ischemia-reperfusion injury was created by the middle cerebral artery embolization. The changes of IL-1β,IL-6 and IL-8 content in the brain tissue were measured by ELISA. The neurological scores were made on Zea Longa 5-point scale. Results In model group, the IL-1β,IL-6 and IL-8 protein content began to increase slightly at 3 hours compared with sham group, reached the peal[at 12 hours. In the aprotinin treated group, aprotinin reduced the protein content. It showed no significant difference between model group and aprotinin treated group at 3 hours, however and there was greatly difference at 6,12 and 24 hours between these two groups. Conclusion The present study provides in vivo evidence that aprotinin protects brain against cerebral ischemia-reperfusion injury. The mechanism is related to the decrease of cerebral levels of IL-1β,IL-6 and IL-8.

Objective To investigate the hemodynamic effects of naloxone in post-resuscitation dog from cardiac arrest. Methods Ventricular fibrillation (VF) was induced, and cardiac output(CO) was measured in 25 dogs before and 6 hours after successful resuscitation from 3 minutes VF. 25 dogs were randomly divided into control group(n=6), CPR group (n=12) and naloxone(NLX) group (n=7). Results Six dogs finished 6-hour experiment in both CPR and NLX groups, and the others did not finish the whole experiment. The time of restoration of spontaneous circulation was not significantly different between CPR group and NLX group. The mean artery pressure(MAP) of CPR group was lower than that of control group in 4, 6 hours after successful resuscitation. The MAP of NLX group was higher than that of CPR group in 2,4 and 6 hours after successful resuscitation, and no significantly different compared with that of normal group. CO in both CPR and NLX groups was lower than that in control group after successful resuscitation. CO in NLX group was higher than that in CPR group in 1 to 6 hours after resuscitation. Conclusion There is myocardial dysfunction in post-resuscitation dog from cardiac arrest. Naloxone can improve their hemodynamic status.

OBJECTIVE: To study protection effect of trasylol on cerebral injury resulting from cerebral ischemia-reperfusion in the interference of immunological response.METHODS: 105 SD rats were randomly assigned into sham operation group,model group and trasylol group (n=35).Focal ischemia-reperfusion model were established by occluding middle cerebral artery.24 h before ischemia and at the 0 h,24 h,4 d,6 d,8 d,10 d,12 d and 14 d of reperfusion,trasylol group were given trasylol via tail vein and other two groups were given normal saline.The infiltration of CD4+ and CD8+ T lymphocytes was observed using immunohistochemistry at different stages of cerebral ischemia-reperfusion.RESULTS: As compared with sham operation group,CD4+and CD8+ T lymphocytes count in model group were increased significantly after cerebral ischemia-reperfusion injury and obtained maximum value at 10th day.CD4+ and CD8+ T lymphocytes count in trasylol group were lower than in model group after cerebral ischemia-reperfusion injury and obtained maximum value at 8th day (P

Currently epidermal growth factor receptor tyrosine kinase inhibitor (EGFR-TKI) is widely used for treatment of non-small cell lung cancer (NSCLC) patients withEGFR mutation. However, intracranial metastasis and progres-sion could happen to some patients while their primary tumors in lung stabilize or even shrink atfer EGFR-TKI treatment. And mechanisms on this phenomenon remain unclear. Recently, increasing studies have demonstrated that it is associated with the pharmacokinetics of EGFR-TKI, heterogeneity between primary tumors and metastases,EGFR mutation status and prolonged survival. hTerefore, we write this review to discuss the mechanisms on intracranial metastasis of NSCLC atfer clinical beneift from EGFR-TKI.

Background and objective Pulmonary sarcomatoid carcinoma is a rare histologic subtype of non-small cell lung cancer. hTe effective treatment for this disease has not well deifned due to its extremely low morbidity. hTis study explores the clinicopathological characteristics and prognosis of 38 patients with PSC, so as to provide some clues for its diagnosis and treatment. Methods hTe study enrolled 38 patients with PSC that were diagnosed with histology or cytology in our hospital between January 2000 and December 2013. We retrospectively analyzed general clinical characteristics, smoking history, tumor size, TNM staging, pathology, immunohistochemistry, diagnostic method, treatment and prognosis. We used SPSS 19.0 statistical sotfware and Kaplan-Meier method to analyze our data. Results Patients in this study were aged from 26 to 76 years old (the median age was 57.5 years old). Among all of them, the male to female ratio was 4:1, and 81.6%of patients had smoking history. Cough and hemoptysis were the most common primary symptoms. hTe median survival was 21 months, while one-year survival rate, three-year survival rate and five-year survival rate were 68.4%, 31.6%and 18.4%respectively. Tumor size, TNM staging, distant metastasis and surgery therapy were associated with the prognosis of patients. Conclusion Patients with PSC present with no special symptoms generally. According to our study, factors that affect patients’ prognosis include tumor size, TNM staging, distant metastasis and surgery. Complete resection is the key treatment for PSC patients, but comprehensive chemoradiotherapy needs further exploration in evidence-based medicine. Biological target therapy may give new insight into treatment for PSC.
