Objective:To investigate the effects of Adp53 and F56 on the growth and lung metastasis of breast cancer.Methods:The BICR-H1 cells were inoculated into the mammary fatty pad of BALB/C nude mice and NOD/SCID mice to establish breast cancer model.Then the nude mice with xenograft tumor were randomized into group Adp53+F56,Adp53,F56 and control.The NOD/SCID mice with xenograft tumor were randomized into group Adp53+F56,Adp53,F56,Adlacz and control.They were theated for 3 weeks according to the plan,diversity of the volume and histopathology of xenograft tumor of nude mice was observed and the expressions of p53 and VEGF gene,and microvessel density(MVD)were detected by immunohistochemistry.Lung metastasis of breast cancer in NOD/SCID mice was observed.Results:(1)Intratumoral injections of Adp53,F56,and their combination resulted in an inhibition on the growth of xenograft tumor of BICR-H1 cells.The ultimate relative growth volumes of groups Adp53+F56,Adp53,F56 and control were 2.47,4.37,4.69 and 12.49 respectively.(2)After treatment,P53 positive rate of group Adp53+F56,Adp53 increased 9.4%,6.3% than before respectively,but compared with control group,the difference is not significant(P=0.693);VEGF protein of group Adp53+F56,Adp53 and F56 decreased 21.9%,9.4% and 3.1% than before respectively,but compared with control group,the difference was not significant(P=0.284).Necrosis and decrease of vessel in the tumor and morphological change of endothelium were observed under light microscope in the groups Adp53+F56,Adp53 and F56.MVD estimated by FⅧ-RA staining of group Adp53+F56,Adp53 and F56 were 14.50?2.54,16.28?3.44 and 18.06?7.66,compared with control group(24.93?6.53),the difference is significant(P=0.000).(3)The average number of lung metastasis of NOD/SCID mice in group Adp53+F56,Adp53 and F56 were 1.143?0.378,2.750?0.886 and 3.375?0.518 respectively,lower than Adlacz group(5.000?0.816)and control group(5.670?0.817)obviously(P=0.000).Conclusion:Adp53 combined with F56 can greatly inhibit growth and matastasis of breast cancer in vivo.The mechanism of anti-tumor effects of Adp53 and F56 may be related to the anti-angiogenesis effect on malignant tumor through inhibiting the expression and activity of VEGF.

Objective To explore the characteristics of food preferences in children with autism spectrum disorder,in order to provide some reference for treating the odd diet habits.Methods Comparing food selection styles through a self-made parents questionnaire including 113 kinds of common food in six categories in China in 162 cases of neurotypical children (NC) and 162 cases of children with autism (AC) to investigate the food preference characteristics of autistic children.Results Compared with NC,AC had narrow food repertoire in grain (NC refuse 0.0(1.0),AC refuse 1.0(2.0),P＜0.001),beans(NC refuse 0.0(1.0),AC refuse 1.0(2.0),P＜ 0.05),meat (NC refuse 0.0 (0.0),AC refuse 0.0 (2.0),P＜ 0.05),vegetables (NC refuse 3.0 (5.0),AC refuse 6.0(1.0),P＜0.001) and fruits(NC refuse 0.0(1.0),AC refuse 2.0(5.0),P＜0.001).There was no difference in the food preferences in neurotypical children of different gender.However,AC boys were more selective in the grain (NA girls refuse 0.0 (1.0),AC boys refuse 1.0 (2.0),P＜ 0.05) and vegetables (NA girls refuse 3.5 (5.0),AC boys refuse 7.0(11.0),P＜0.05) than AC girls.Moreover,AC had higher preference to lower acceptance in most of food than NC,but not instant noodles(NC acceptance 71.01％,AC acceptance 81.02％,P＜0.05) and chilli (NC acceptance 20.71％,AC acceptance 28.47％,P＜0.05).Conclusion Compared with NC,AC have narrower food repertoire.On the other hand,AC have significantly higher acceptance of stimulating food like chili and instant noodle.

ObjectiveTo examine the prognostic value of 99mTC-MIBI single-photon emission computed tomography (SPECT) in patients with suspected or diagnosed coronary artery disease (CAD).Methods116 patients with suspected or diagnosed CAD were examined with 99m TC-MIBI SPECT exercise and rest myocardial imagings, and followed by investigation of cardiac events.Results Follow-up information was complete in 106 patients. Over an average follow-up of 25±8 months, cardiac events occurred in 11 patients. Univariate analyses showed that age, old myocardial infarction, exercise peak heart rate, the change in heart rate from rest to exercise peak, exercise peak systolic blood pressure, the change in systolic blood pressure from rest to exercise peak, abnormal myocardial imaging, the number of myocardial perfusion defect and ischemic volume rate (IVR) were the effective predictors of subsequent cardiac events. Multivariate stepwise Logistic regression analyses revealed that the size of IVR was the only variable with independent predictive value for occurrence of subsequent cardiac events. IVR more than 25% was associated with a significantly increased frequency of subsequent cardiac events (relative risk ratio was 5.9, P<0.005). IVR less than 25% or even normal myocardial perfusion imaging was associated with a very low-risk of cardiac event and a very good prognosis.Conclusion 99mTC-MIBI SPECT myocardial imaging is the most effective noninvasive technique that predicted the occurrence of cardiac event in patients with suspected or diagnosed CAD. According to the size of IVR, high-risk and low-risk patients can be effectively identified.

Fibrolase is a non-hemorrhagic zinc metalloproteinase isolated from southern copperhead snake venom (Agkistrodon contortrix contortrix) and is capable of degrading fibrin clots resulting from purified fibrinogen or from blood plasma. Alfimeprase, a truncated form of fibrolase, as a clinical agent was successfully completed PhaseII clinical trials.The cDNA of alfimeprase was amplified by recursive PCR, digested with BamHI and HindII, and cloned into pET43.1a, pMALp2X and pMALc2X vectors to generate fusions with NusA, MBP and sMBP(with signal peptide), respectively. Nus/alfimeprase was expressed in soluble form by co-expressing with chaperone FkpA and inducing with1mmol/L IPTG. The fusion protein accounted for about 25 % of total protein following cell lysis. Alfimeprase was successfully purifiesd by Ni-NTA affinity chromatography and cleaved by enterokinase. The results demonstrate the fibrinolytic activity of recombinant alfimeprase using fibrin plate assays and fibrinogen hydrolysis.

ObjectiveTo compare the efficacy and side effects of ilioinguinal/iliohypogastric nerve blockades and rectal paracetamol after pediatric inguinal hernia repair.MethodsNinety children undergoing half inguinal hernia repair were randomly divided into 3 groups:nerve block group(n=30),paracetamol group(n=30) and control group(n=30).After basal anesthesia,ilioinguinal/iliohypogastric nerve blockades was administed in nerve block group,paracetamol group received rectal paracetamol,control group had not any medication.Every child was oberserved 1,3,6,8 h postoperatively for pain score,overall satisfaction were evaluated by parents,furthermore,evaluation of distress for children such as nausea,vomiting and delayed femoral nerve palsy was made.ResultsPain scores were significantly lower in nerve block group and paracetamol group during the postoperative follow-up 1,3 and 6 h.Overall satisfaction in nerve block group and paracetamol group were significantly higher than control group.The incidence of delayed femoral nerve palsy in nerve block group was higher than paracetamol group(F=4.22P
