Objective To study protective effect and mechanism of caffeic acid phenethyl ester ( CAPE ) in rats with doxorubicin-induced myocardial injury.Methods Sixty male SD rats were randomly divided into control group, model group and CAPE ( 12、24、48 mg/kg ) groups.The models of doxorubicin-induced myocardial injury were established by injection of 2.5 mg/kg doxorubicin every other day for 6 times.After the last injection, model group was given distilled water and CAPE ( 12、24、48 mg/kg ) groups were fed with CAPE, one time a day for 8 weeks.After consecutive 8 weeks, serum creatine kinase, lactate dehydrogenase and BNP were assessed , NO concentration, MDA,GSH,SOD,NOS,LPO and CAT contents in the heart were determined and histopathological changes were detected.Results serum creatine kinase、lactate dehydrogenase and BNP of CAPE 48 mg/kg group decreased significantly(P<0.05), while the activity of NO,NOS,GSH,CAT and SOD increased in the CAPE 48 mg/kg group significantly ( P<0.05 ) .Histopathology showed caffeic acid phenethyl ester could improve the doxorubicin-induced myocardium injury. Conclusion caffeic acid phenethylester has the protective effects in rats with doxorubicin-induced myocardial injury.Protective effect may be related to improve myocardial against oxidative stress damage.

Objective:To investigate the relationship between marriage/loving affairs related life events and the high suicide rates among Chinese rural women.Methods: 66 suicides and 66 living controls were studied using psychological autopsy methods.Results:There were 36 women in the research subjects which account for 27% of the total sample (36/132). There were more marriage/loving affairs related life events in female suicide than in other groups (1.6?2.1 vs. 1.0?1.5,0.2?0.6,0.6?0.9) and in female suicide the frequency of marriage/loving affairs related life events is higher than the frequency of other four types of life events (1.6?2.1 vs. 0.5?0.7,0.4?0.6,0.9?0.9,0.4?0.9). Both of the two differences do not have statistical significance.Conclusion:More attention should be paid to marriage/loving affairs related life events for Chinese rural women.

Objective To explore the role of receptor-interaction proteins(RIP) in phenethylisothiocyanate(PEITC)-induced apoptosis in human leukemia cells.Methods U937 cells were exposed to PEITC at various concentrations of 0,2,4,6 and 8 ?mol/L for 3 and 6 h,or at 8 ?mol/L for different time intervals of 1,3,6,9,12 and 24 h.Cells were stained with Annexin V/PI,and apoptosis was determined by using flow cytometry.Total protein extracts were prepared and subjected to Western blot assay using antibodies against poly(ADP-ribose)polymerase(PARP),Caspase-3,Caspase-8,and RIP.?-actin was used to ensure equivalent loading.Results After exposure to PEITC at concentrations of 2,4,6 and 8 ?mol/L for 3 h,U937 cells showed an increase in cell apoptosis(9% ,25% ,44% and 56% respectively).While when the time expanded to 6 h,the amount of apoptotic cells was increased to 16% ,28% ,51% and 82% respectively.A dose-dependent manner was seen when U937 cells were exposure to PEITC at different concentrations.When U937 cells were treated by PEITC at concentration of 8 ?mol/L for 1,3,6,9,12,and 24 h,the apoptotic cells covered 12% ,57% ,79% ,86% ,90% ,and 91% of all cells respectively,indicating a time-dependent manner.Western blot assay showed that PEITC caused the activation/cleavage of Caspase-3 and-8,and improved the PARP cleavage,and also decreased the expression of RIP.PEITC-induced apoptosis was proceeded by degradation of RIP.Conclusion Our results indicate that PEITC induces the apoptosis in human leukemia cells through a process that involves death receptor pathway,and RIP may play an important role in the apoptosis.

Objective: To evaluate the effect and safety of low-dose naloxone combined with sufentanil and ropivacaine for postoperative patient-controlled epidural analgesia (PCEA) in elderly patients undergoing total hip replacement. Methods: A total of 60 elderly patients (ASA I-II) undergoing total hip replacement were randomly assigned to two equal groups: Group C was given 0.5 μg/ml sufentanil in 0.15% ropivacaine; Group N was given the same solution with 0.09 μg/(kg·ml) naloxone. The 2 groups were followed up in a double-blinded manner: the visual analogue scale (VAS) for pain score was recorded at 2, 6, 12, and 24 h to evaluate the analgesia effect. Meanwhile, the incidences of postoperative nausea and vomiting (PONV), pruritus, sedation, respiratory depression, and hypotension were also recorded. Results: The VAS pain score in Group N was significantly lower than that in Group C at 6, 12 and 24 h (P<0.01). The incidence of PONV in Group N was significantly lower than that in Group C (P<0.05); the incidences of other opioid-induced side-effects were not significantly different between the 2 groups. During the course of analgesia, the vital signs of 2 groups were stable; no patients had respiratory depression or hypotension. Conclusion: Low-dose epidural naloxone can enhance the analgesic effect of sufentanil. With timely postoperative monitoring, low-dose naloxone combined with sufentanil and ropivacaine is safe and effective for postoperative patient-controtled epidural analgesia in elderly patients undergoing total hip replacement.

Epithelial mesenchymal transition (EMT) is a process of normal cell physiological development, in which epithelial cells transform into mesenchyme cells through a specific program. EMT plays a key role in inflammatory reaction, cell development, tumor invasion, and metastasis and has an interrelation with prostate cancer stem cells. Recent researches show the involvement of EMT in the development and metastasis of prostate cancer. This article reviews the specific roles and action mechanisms of EMT in the progression of prostate cancer.

Objective To investigate the characteristic of intravascular catheter-related infections (CRI) in Peking University Third Hospital in 2009. Methods The clinical and microbiological features of CRI were analyzed retrospectively. Results Two hundred and nineteen catheters were examined. Twenty-nine CRI cases were confirmed with colonization, 7 were insertion site infection and 6 were catheter-related bloodstream infections (CRBSI) by quantitative catheter culture method, but no CRBSI was diagnosed by differential time to positivity (DTTP) method. The incidence rates of CRBSI in intensive care units (ICU) were 0. 99- 3.03 per 1000 catheter-days.Among the colonized strains, 51.72 % were Gram-positive cocci, 20.69 % were non-fermenting bacilli (NFB), 13. 79% were Enterobacteriaceae and 10. 34% were Candida. One neonatal CRBSI was caused by Leuconostoc mesenteroides. Most of bacterial isolates were drug resistant. Seventy-seven percent of adult patients were older than 60 years and most of them had chronic underlying diseases.All of the 9 neonate patients were preterm neonate and 7 of them were extremely low birth weight infants. Conclusion There is a certain amount of CRI occurred in Peking University Third Hospital in 2009 and the intravascular catheter management should be enhanced.

Objective To investigate the microbiological and epidemiological characteristics of bloodstream infections in Peking University Third Hospital Methods The clinical, microbiological and epidemiological data of bloodstream infections in Peking University Third Hospital from January lst,2005 to December 31st, 2007 were analyzed retrospectively. Differences in proportions were compared using X2 test. Results Six thousand four hundred and eighty-eight blood culture tests for 5 138 episode of bloodstream infections of 3 795 patients were performed. The positive rate was 9.9%. The average incidence rate of nosocomial infection was 40.8 cases per 10 000 hospital admissions. In the 593 pathogens, 483 (81.5%) were pathogens causing nosocomial. The ratio of Gram-positive microbs, Gram-negative ones and fungi (all were Candida spp.) were 38.5%, 54.7%, and 6.8%, respectively. The corresponding ratio of nosocomial pathogens were 42.0%, 49.9% and 8.1%, respectively. The most frequently isolated strain was Escherichia coli (25.3 %). The coagulase negative staphylococcus was the second one (18.8%). The corresponding ratio of Staphylococcus aureus, Klebsiella pneumoniae, Enterococcus spp. , Pseudornonas aeruginosa , Acinetobacter baumannii and anaerobs were 7.1%, 7.4%, 8.3%, 3.2%, 2.2% and 0.7%, respectively. Ten patients (1.7%) had experienced polymicrobial infection. In hospital setting, Streptococcus spp. And Escherichia coli infections were more frequently in non-intensive care unit (ICU) than ICU (X2= 9.240, P= 0.002; X2= 23.609, P,<0.01; respectively). But the infection rate of Candida spp. Was significantly higher in the ICU (X2= 5.498, P= 0.019). The time interval between hospital admission and onset of infection for the most frequently isolated pathogens ranged from 15.1 days (Escherichia coli) to 29.7 days (Acinetobacter baumannii). The degree of resistance to the common antimicrobal agents had no change in the three years. Conclusions The average incidence rate of nosocomial bloodstream infection is 40.8 cases per 10 000 hospital admissions. The main pathogens are the Gram-negative microbs.
