Objective To investigate the relevant factors of neonatal ventilator-associated pneumonia(VAP),and to provide a theoretical basis of prevention and treatment.Methods Retrospective analyed the clinical data of 145 critically ill neonates,who were treated with mechanical ventilator from Jan 2006 to Dec 2009 in the Third People′s Hospital of Wenzhou City,NICU.According to whether the neonates were occurred VAP,they were divided into two groups:VAP group(52 cases) and without VAP group(93 cases).Results Fifty-two out of the 145 neonates developed VAP.The incidence of VAP was 35.86%,the main relevent factors were the gestational ages,birth weights,the duration of mechanical ventilation and the times of intubation.There was significant difference between the two groups (P<0.05).The main pathogens were opportunistic bacteria,and mostly were G-bacilli.Conclusion The incidence of VAP has a close conclusion with the gestational ages,the birth weights,the duration of mechanical ventilation and the times of intubation.Regulate the use of breathing machine,strengthen aseptic operation,and select effective antibiotic can control the occurrence and development of VAP.

Radiation-induced lung injury is a common complication of thoracic cancer radiotherapy.A lot of animal experiments and clinical studies have shown that ionizing radiation-induced lung injury is a complex process regulated by a variety of cytokines.The transcription factors including nuclear factor κB,MAPK and activator protein-1 are involved in radiation-induced lung injury by regulating the synthesis of a variety ofinflammatory proteins.The flavonoids play a role in radiological protection by blocking the pathway of nuclear factor kB and activator protein-1.

Human T-cell leukemia virus type 1 (HTLV-1) is a retrovirus demonstrated to be associated with human disease. Infection by the HTLV-1 can cause T-cell leukemia (ATL) in adults. HTLV-1 bZIP factor (HBZ) is a viral protein encoded by the minus strand of the HTLV-1 provirus. Among the regulatory and accessory genes of HTLV-1, HBZ is the only gene that remains intact and which is expressed consistently in all patients with ATL. Moreover, HBZ has a critical role in the leukemogenesis of ATL. Here, we review the function of HBZ in the oncogenesis of HTLV-1 and its molecular mechanism of action.

Objective:To analyze the effects of protein intake of varied dietaries on the pregnancy of pregnant women.Methods:The pregnant women who had their medical records in our hospital were included in this study.Their dietary were collected based on the respective review of their food during 24 hours when they visited the Nutrition Clinics between 24 weeks and 28 weeks.The subjects were divided into six groups according to the dietary calories and protein intake:group A (normal calorie and normal protein),group B (normal calorie and low protein),group C (normal calorie and high protein),group D (high calorie and normal protein),group E (high calorie and high protein) and group F (low calorie and low protein).The gestational diabetes mellitus incidence rates,levels of fasting blood glucose (FBG),blood glucose (BG),hemoglobin Alc (HbAlc),and blood lipids,and bone mineral density were compared among six groups.Results:The gestational diabetes mellitus incidence rate,levels of postprandial blood glucose at 1 hour and 2 hour in groups of B,C,D,and E were significantly higher than those in group A (P ＜ 0.05).The levels of triglyceride,total cholesterol,and low density lipoprotein cholesterol were remarkably higher in groups of B,D,and E than those in group A (P ＜ 0.05).The bone mineral density was significantly lower in group A than that in groups of C,E,and F (P ＜ 0.05).Conclusion:The diet with normal calorie and normal protein is the scientific dietary structure.The pattern with high calorie and high protein intake is not recommended for pregnant women.

Objective To explore the relationships of post- traumatic growth with self- care efficacy and psychological resilience in patients with breast cancer. Methods Totally 303 patients with breast cancer were investigated with Post- traumatic Growth Inventory (PTGI), Chinese version of Strategies Used by People to Promote Health (C- SUPPH) and Connor- Davidson Resilience Scale (CD- RISC). Results The total score of PTGI was 63.74±13.00 and the status of post- traumatic growth in breast cancer patients was in middle level, with a highest interpersonal score of 24.49±5.05, a lowest mental change score of 3.84± 1.91. Correlation analysis showed that post- traumatic growth was positively correlated with the level of self- care efficacy and psychological resilience (P<0.01 or 0.05). Regression analysis showed that self- care efficacy and psychological resilience in breast cancer patients could effectively predict the post- traumatic growth with an explanation rate of 36.1%. Conclusions Self- care efficacy and psychological resilience in patients with breast cancer are closely correlated with post- traumatic growth. It is suggested to take appropriate measures to promote post-traumatic growth of the breast cancer patients.

Aim To investigate the effect of intracerebroventricular morphine postconditioning against ischemia-reperfusion injury in rat heart and the mechanism of the central nervous system opioid receptor.Methods Forty-two Sprague-Dawley Rats were established intracerebroventricular catheter placement and myocardial ischemia/reperfusion models and randomly assigned to 7 groups:Sham group(Sham),control group(CON),intravenous control group(VCON),morphine postconditioning group(POC),intracereborventricular morphine postconditioning group(MOC).According to the dosage of intracerebroventricular morphine(3 ?g?kg-1,0.3 ?g?kg-1,0.03 ?g?kg-1),MOC group was assigned to three groups :MOC 1,MOC 2,MOC 3.Infarct size(IS),a percentage of the area at risk(AAR) was determined by triphenyltetrazolium(TTC) staining.c-fos expression in nucleus of tractus solitarius was determined by immunohistochemical method and Cardiac TroponinI(cTnI) of serum was observed at 120 min of reperfusion.Results Compared with control group,IS,IS/AAR and cTnI were significantly reduced in POC and MOC groups(P0.05).c-fos expression in nucleus of tractus solitarius were significantly reduced in MOC 2,POC(P

Background and purpose: 18F-FDG has been considered to be of limited value for the detection of bladder lesions because of interference by the 18F-FDG excreted in urine. Delayed pelvic images with“diluted and iflled bladder”use a method of 18F-FDG PET/CT with delayed images after oral hydration so as to increase the detection rate of 18F-lfuorodeoxyglucose(FDG) PET/CT imaging for the lesions of bladder. Methods:48 patients with bladder lesions(35 patients with bladder primary tumor and 13 patients with metastatic tumor) underwent 18F-FDG PET/CT detection and were required oral hydration of 1200-1800 mL water, urination frequently, holding urine when the more scan began. Lesions conifrmed by histopathology, MRI, CT or clinical follow-up at least 1 year. Results:89%(43/48) of patients were obtained good clearance and the urine SUVmax declined from 33.14(9-66.80)to 3.23(1.35-5.65) signiifcantly and the statistical difference was signiifcant (t=8.703, P<0.01). The interval time between two scan was 2 h approximately. At the same time, the SUVmax of bladder lesion was 2.8-25.0. Detection sensitivity, speciifcity and accuracy were 90.47%(19/21), 81.48%(22/27)and 85.41%(41/48), respectively. Conclusion: 18F-FDG activity in the bladder signiifcantly decreased in most patients with“diluted and iflled bladder”. The PET/CT scan can highly detect lesions of bladder tissues. Our method with high accuracy and better endurance could be applied to detect the lesions in bladder.
