Objective To investigate the protective effect of Xinyi capsule pretreatment on myocardial ischemia reperfusion injury in rabbits and its possible mechanism. Methods Ninety-four rabbits were randomly divided into 6 groups: model group (n=16), tirofiban group (n=16), high-, medium- and low-dose Xinyi capsule groups (4.0, 2.0, 1.0 g/kg;n=16 in each group), and sham operation group (n=14). Five days after intragastric administration with drug, myocardial ischemia reperfusion was induced by ligation of the proximal left circumflex artery. The electrocardiogram (ECG) was continuously recorded. The serum levels of myeloperoxidase (MPO), lactate dehydrogenase (LDH) and creatine kinase-MB (CK-MB) were measured. Myocardial histopathological damage was evaluated. Results The changes of J-point amplitude on ECG in high-, medium-and low-dose Xinyi capsule groups (0.064 ± 0.049 mV, 0.069 ± 0.061 mV, 0.079 ± 0.060 mV) were significantly lower than that in the model group (0.158 ± 0.105 mV, P<0.01 or P<0.05), the serum levels of LDH (399.7 ± 202.3 U/L, 369.6 ± 229.0 U/L, 435.5 ± 152.4 U/L), CK-MB (900.8 ± 231.2 U/L, 1 268.3 ± 899.8 U/L, 1 386.7 ± 621.6 U/L), MPO (69.81 ± 5.51 U/L, 85.44 ± 10.31 U/L, 81.33 ± 16.87 U/L) were significantly lower than those in the model group (LDH:817.1 ± 401.9 U/L, CK-MB:2 071.3 ± 693.5 U/L, MPO:149.9 ± 20.11 U/L;P<0.01 or P<0.05). Histopathological examination showed that myocardial damage in high-, medium- and low-dose Xinyi capsule groups reduced compared with the model group. Conclusions Xinyi capsule pretreatment can protect against myocardial ischemia reperfusion injury in rabbits, and its mechanism may be related to inflammation inhibition.

Objective To study the effect of three different modes of non-invasive positive pressure ventilation on cardiac indices of premature infants with respiratory distress syndrome (RDS).Method From January 2014 to October 2015,preterm infants who had RDS received intubation-pulmonary surfactantextubation in the neonatal intensive care unit of the Hospital were randomly assigned (by random number table) to three groups based on the primary mode of ventilation:nasal continuous positive airway pressure (NCPAP),bi-level positive airway pressure (BiPAP),and synchronized bi-level positive airway pressure (SBiPAP).The mean airway pressure (MAP) were about 6 cmH2O in the three groups.The level of plasma B-type natriuretic peptide (BNP),cardiac troponin Ⅰ (cTnI),and correct QT intervals dispersion (QTcd) were monitored before and 42-54 h after non-invasive ventilation.Result There were 173 cases in our study,59 of which in NCPAP group,56 in BiPAP group,and 58 in SBiPAP group.The plasma BNP level at 42-54 h after non-invasive ventilation in the three groups were all higher than that before non-invasive ventilation [NCPAP group:(247.9 ± 137.9) ng/L vs.(182.5 ± 1 10.7) ng/L,P =0.007;BiPAP group:(258.5 ± 131.2) ng/L vs.(182.6 ± 105.0) ng/L,P ＜ 0.001;and SBiPAP group:(260.9 ± 159.7) ng/L vs.(177.5 ± 101.5) ng/L,P =0.002].After 42-54 h non-invasive ventilation,there were no significant changes of plasma cTnI level and QTcd in all the three groups (all P ＞ 0.05).The level of plasma BNP,cTnI,and QTcd among the three groups before and after 42-54 h non-invasive ventilation all showed no significant differences statistically (all P ＞ 0.05).Conclusion Longer duration (42-54 h) of non-invasive positive pressure ventilation (MAP:6 cmH2O) in preterm infants with RDS may lead to increased plasma BNP level,and may affect their cardiac function.However,it may not lead to serious myocardial damage and abnormality of ventricular repolarization.There were no significant differences in cardiac indices of premature infant with RDS among NCPAP,BiPAP,and SBiPAP group with the same MAP.

Objective To evaluate the effect of pre-emptive analgesia on pain and inflammation control in patients with severe multiple trauma.Methods Severe multiple trauma patients treated in the emergency department from September 2014 to December 2014 were prospectively included based on the inclusion criteria including injury severity score (ISS) of 16 to 25,Glasgow Coma Scale (GCS) ≥ 13 and visual analogue scale (VAS) ≥ 4.The patients were assigned to pre-emptive analgesia group,traditional analgesia group and non-analgesia group,according to the random number table.Pre-emptive analgesia group had patient-controlled intravenous analgesia (PCIA) with sufentanil and tramadol on admission.Traditional analgesia group were administered intramuscular pethidine or subcutaneous morphine for temporary analgesia when the pain could not be tolerated.Non-analgesia group received no analgesia.VAS,systemic inflammatory response syndrome (SIRS) score and serum interleukin (IL)-6 concentration were compared among the groups on admission day,24,48,72,120,168 and 240 h after admission.Results Fifty-seven patients (46 males and 11 females) were included,and age was (39.61 ± 12.05)years.There were 18 patients in pre-emptive analgesia group,20 patients in traditional analgesia group,and 19 patients in non-analgesia group.Comparison between pre-emptive analgesia,traditional analgesia and non-analgesia groups showed no significant differences on admission with respect toVAS [(6.5±1.5),(6.6±1.4),(6.4 ±1.4)points],SIRS [(3.3±0.7),(3.4±0.6),(3.4±0.8) points] and IL-6 concentration [(109.2 ± 47.9),(99.9 ± 44.3),(106.3 ± 50.0) ng/L] (P ＞0.05).Compared to traditional analgesia and non-analgesia groups,VAS and SIRS score in pre-emptive analgesia group differed significantly at 24,48,72,120,168 and 240 h after admission,and IL-6 in pre-emptive analgesia group differed significantly at 48,72,120,168 and 240 h after admission (all P ＜0.05).VAS,SIRS score and IL-6 concentration declined faster in pre-emptive analgesia group than other two groups (P ＜ 0.05),while there were no significant differences between traditional analgesia and nonanalgesia groups (P ＞ 0.05).Positive correlation was noted between VAS and SIRS score,and between VAS and t IL-6 concentration (P ＜ 0.05).Conclusion Pre-analgesia provides quick and effective pain relief and attenuate excessive systemic inflammation response that contributes to stabilization and recovery of the severe multiple trauma patients.

Objective To investigate the changes of cardiac function at pre -and post -treatment in preterm infants with patent ductus arteriosus (PDA)in order to guide drug treatment.Methods Totally 84 preterm infants with PDA admitted to Neonatal Intensive Care Unit of Xuzhou Hospital Affiliated to Medical College of Southeast University from July 201 2 to June 201 4 were divided into 4 groups according to treatment drug:Ibuprofen group (27 cases),Indo-methacin group (24 cases),control group (1 1 cases),and Paracetamol group (22 cases).Patients were also divided into symptomatic PDA group (38 cases)and asymptomatic PDA group (46 cases)according to severity;PDA closed group (69 cases)and PDA unclosed group (1 5 cases)according to sequel.The level of plasma brain natriuretic pep-tide (BNP),cardiac troponin I (cTnI),correct QT intervals dispersion (QTcd)were monitored pre -and post -treat-ment.Data were analyzed by using SPSS 1 9.0 software.Results Three cardiac markers at post -treatment were of no significant difference among 4 treatment drugs.The changes of the cTnI and QTcd at pre -and post -treatment were of no significance.The level of BNP in symptomatic PDA group was significantly higher than that in asymptomatic PDA group at pre -treatment [(378 ±94)ng/L vs (1 47 ±75)ng/L,t =2.584,P =0.01 4].In the symptomatic PDA group,the level of BNP at post -treatment [(1 82 ±81 )ng/L]was significantly decreased than that at per -treatment (t =2.741 ,P =0.009).In the asymptomatic PDA group,there was no significant difference between the pre - and post -treatment [(1 21 ±61 )ng/L]in the level of BNP (t =1 .254,P =0.207).There was no significant difference in the level of BNP at per -treatment between PDA closed group and PDA unclosed group [(274 ±91 )ng/L vs (289 ± 87)ng/L,t =-0.874,P =0.391 ].In PDA closed group,the level of BNP at post -treatment [(1 21 ±74)ng/L] was significantly decreased compared with that at per -treatment (t =3.580,P =0.000).In PDA unclosed group, there was no significant difference between the pre - and post -treatment [(245 ±74)ng/L]in the level of BNP (t =0.854,P =0.392).Conclusion Early medication intervention for symptomatic PDA of preterm infants is benefi-cial for the closure of PDA and for attenuating negative effects on cardiac function of PDA.

Aim To explore the anti-apoptotic function of cardiac progenitor cells(CPCs)-derived exosome in vitro.Method CPCs were isolated from mouse heart using Magnetic Cell Sorting(MACS)system.Flow Cy-tometry(FC)determine the purity of stem cell surface antigen-1 positive(Sca-1 +)CPCs.Exosome was puri-fied from conditional medium,and confirmed by West-ern blot using CD63 as a marker,Nanoparticle Traffic-king Analysis(NTA)was used to detect the diameters and concentration of exosome.Then the cells were di-vided into control groups and CPC-exosome pre-protec-tion groups.H2 O2 was added into H9c2 cells to induce oxidative stress.Western blot was adopted to determine the expression of cleaved caspase-3.Results ① Im-munofluorescence showed that CPCs isolated by MACS were positively expressing Sca-1 protein;FC analysis showed that typical purity of Sca-1 +CPCs from the first
preparations was more than 95%.② WB demonstrated that CD63 of exosome isolated from CCMwas positively expressed,and NTA results showed that the diameters of exosome were (82.33 ±3.06)nm(n =3).Micro-scope detected PKH-26 labeled exosome appeared in the cytoplasma of H9c2 cells.③ Western blot showed the CPC-exosome pre-protection groups significantly down-regulated the levels of cleaved caspase-3 com-pared to the control groups(P <0.05).Conclusion CPC can secrete exosome which carries many important cargos,which can effectively gather in H9c2 cells. CPC-exosome can protect H9c2 cells from the oxidative stress induced by H2 O2 .Our results highlight a new perspective strategy for cardiac disease.

Objective To summarizes the experiences and technique of complex transradial percutaneous coronary intervention (PCI) using sheathless guide catheter (Sheathless Eaucath, ASAHI) for 60 patients with coronary heart disease. Methods Retrospectively analyzed the data from 60 patients received PCI using sheathless guide catheter. Results PCI were performed on a total of 60 patients with complex lesions. Angiographic success was achieved in 95.0%and failed in three patients with CTO. 7 patients were with left main lesions, and 32 patients were with bifurcation lesions(including 7 patients with left main lesions and 2 patients with CTO), and 13 patients were with CTO, and the other 17 patients were with tortuous and calcified lesions. Sheathless guide catheters of 7.5Fr were used for PCI in all patients, and all catheters successfully passed through the radial artery and were put in place. No other vascular complications associated with the use of the catheter occurred. Sheathless guide catheters were respectively JL(8 patients), PB(2 patients), AL(2 patients), and JR(1 patient) in 13 patients with CTO, and were respectively JL(8 patients), JR(6 patients), SPB(2 patients), AL(1 patient) in 17 patients with tortuous and calcified lesions. JL or JR were used in all 32 patients with bifurcation. Conclusions Use of the Sheathless of 7.5 Fr is safe and feasible, and allows complex interventions to be undertaken transradially with a high success rate.

Objective:To explore and optimize the teaching content of clinical case discussion course based on clinical pathophysiology and therapy (CPPT), and to improve the teaching quality of this course.Methods:Self-compiled evaluation form was sent to all the students who participated in this course in 2016-2017 school year, and the teaching satisfaction and teaching characteristics were evaluated. The differences of evaluation results from students with different educational programs or teachers with different seniority were compared, and the correlation between evaluation results and teachers' seniority was analyzed.Results:The students had a high evaluation on the course, but students from different programs had significant different comments on thinking inspiring, speech encouraging, questions guiding, process holding and effective feedback, as well as the self-evaluation of mastery degree. For teachers with different seniority, there were significant differences in scores in all aspects except speech encouraging, but no differences in mastery degree. Spearman analysis showed that there was a certain correlation between scores and teachers' seniority.Conclusion:The overall situation of the CPPT case discussion course in our school is worthy of recognition, but it needs to be improved in many aspects.

Objective To investigate the MR findings of fetal cleft lip (CL) and evaluate the advantages and limitations of MRI in the diagnosis. Methods Twelve pregnant women suspicious of fetal CL/cleft palate(CP) on ultrasonography were enrolled in the study. The findings of ultrasonography, MRI and following-up were compared. Results MRI and ultrasonography detected 12 fetuses with CL/CP. The following-up results showed 1 case with incomplete cleft lip and the other 11 cases with complete cleft lips and cleft palates. MRI and unltrasonography were consistent with the follow-up in CL detection, showing completed or uncompleted soft tissue interruption of the fetal lips with amniotic fluid filling which is high signal on T_2WI. On MRI, CP showed discontinuous of the soft tissue which were interrupted by long T_2 signal and communicating with oral cavity and nasal cavity. MRI missed 1 case and excluded 1 case of CP. Ultrasonography predicted 5 case of CL, excluded 1 CP but missed 6 cases. The accuracy, sensitivity and specificity in detection CL/CP was 91.7% (11/12), 90.9% (10/11), 100% (1/1) for MRI and 50.0% (6/12),45.5% (5/11), 100% (1/1) for ultrasonography, respectively. Conclusion MR imaging had advantage over ultrasonography in detecting CP, MRI is an essential when CP is suspicious on ultrasonography.

Objective To observe the dynamic changes of hepatic ischemia reperfusion injury ( IRI) by contrast enhanced ultrasound(CEUS) in rabbit model and investigate its clinical value . Methods Sixty rabbits were randomly assigned into seven groups :sham operation group and 6 hepatic IRI groups ( 0 .5 h ,2 h ,6 h ,12 h ,24 h ,72 h) . The rabbits of hepatic IRI group established as follows :the hepatic artery , portalvein and bile duct in the portal triad to the left liver lobes were interrupted for 60 min with a vascular clip and then reflow the blood . The perfusion imaging of left liver lobe was observed and then the peak signal Intensinty ( PI) ,time to peak intensinty ( Tp) ,area under the curve ( AUC) ,and mean transit time ( MTT ) were calculated . The rabbits were sacrificed and blood samples were withdrawn for the measurement of liver enzymes aspartate aminotransferase ( AST) and alanine aminotransferase ( ALT) ,liver samples from the left lateral were collected for the measurement of myeloperoxidase ( MPO) and histologic examination . The correlation between parameters of CEUS and the test results above were analyzed . Results There were significant differences in the parameters of CEUS between hepatic IRI group and sham group ( P < 0 .001) . PI and AUC showed a decreased tendency and the lowest values were measured in the 24 h group .Tp and MTT showed a upward tendency and the maximum values were measured in the 24 h group . The parameters of CEUS showed correlation with ALT ,AST and MPO ( P < 0 .001 ) . AUC showed significant correlation with ALT ,AST and MPO ( r = - 0 .702 , - 0 .802 , - 0 .846 ;all P < 0 .001 ) . Conclusions CEUS can assess liver functional and pathological changes in the process of hepatic IRI in real-time ,dynamically ,rapidly ,noninvasively and objectively . It is expected to replace the invasive pathological inspection . AUC is the best index for evaluating hepatic IRI in parameters of CEUS .
