Objective To investigate the safety,efficacy and effects of emergent percutaneous coronary intervention (PCI) in patients from Second Affiliated Hospital,Medical College,Zhejiang University with cardiogenic shock (CS) complicating acute myocardial infarction (AMI).Method Twenty-seven patients with CS complicating with AMI were treated by PCI with intraaortic balloon counterpulsation (IABP) support.The change of hemodynamics before and after IABP and PCI,the characteristics of PCI,the mortality during hospitalization, the major adverse cardiac events (MACE) and left ventricular ejection fraction at 30-day follow-up were observed.Results The hemodynamics were significantly improved after IABP.No patients died during PCI.Two patients died after PCI and the total mortality was 7.4% in hospital.During the period of 30-day follow-up, one patient died of heart failure.The left ventricular ejection fraction greatly improved at 30 days after PCI. Conclusions The data suggested that the use of IABP during PCI in patients with CS complicating AMI was safe, decreased mortality and improved prognosis.

Objective To discuss the diagnosis and inductive chemoradiotherapy of stage Ⅲ and stage Ⅳa invasive thymoma.Methods Clinical data of 13 cases with incomplete resected invasive thymoma were analyzed retrospectively,among which 8 cases were in stage Ⅲ and 5 cases in stage Ⅳa.All the 13 cases had invasion of major vessels,pericardial and lung tissues,or had metastasis of pleura and pericardium.Each patient got pathological diagnosis by fine needle aspiration,video-assisted thoracoscopic biopsy or anterior mediastinal biopsy.After 3 cycles of NP or CAP inductive chemotherapy and synchronous radiotherapy,tumors shrank and got palliative or complete surgical resection.The Follow up ranged from 2.8 to 9 years.Results All the 13 cases were malignant thymoma,including 4 cases of type B2,6 cases of type B3 and 5 cases of type C.7 patients got radical resection and 2 got palliative resection.9 patients survived more than 3 years after operation,7 patients survived more than 5 years,one patient even lived 8 years,and the other 4 patients without getting surgery died in 4 years.Conclusion Inductive chemoradiotherapy could shrink stage Ⅲ and stage Ⅳa invasive thymoma,reduce clinical stage,improve the resection rate,and prolong survival.

Objective To study the correlation between serum bilirubin and restenosis after stent implantation of coronary heart disease (CHD).Methods Two hundred and fourtynine patients with CHD were divided into Instent-restenosis (ISR) of CHD group and non-ISR of CHD group according to their angiography findings.Theirserum bilirubin levels were compared and correlation between serum bilirubin level and ISR of CHD was studied.Results The serum bilirubin level was significantlylower in ISRof CHD group than in non-ISR group (P ＜ 0.05),in TBIL (9.9322 ± 3.8748μmol/L) to (12.08 ±4.6679μmol/L)、DBIL (3.1744 ± 1.60μmol/L) to (3.8949 ± 1.825μmol/L)、IBIL (6.757 ±2.822μmol/L) to (8.174 ± 3.388μmol/L).Conclusions The serum bilirubinlevel is lower in CHD patients with ISR than in CHD patients with non-ISR,which is an indepent risk factor for ISR of CHD.

Objective To investigate the effect of intracoronary application of tirofiban on coronary slow flow patients with acute myocardial infarction during primary percutaneous coronary intervention (PPC1).Method It was a retrospective analysis of 187 patients with acute myocardial infarction treated with PPCI in the emergency department of Beijing Anzhen Hospital enrolled in this study from January,2008 through January,2011.The patients divided into 2 groups in terms of intra-coronary administration of tirofiban (tirofiban group) and intra-coronary use of nitroglycerol (control group).Data were statistically analyzed by using SPSS 13.0 software.Categorical variables were analyzed using x2 test and continuous variables were compared by t test.Results Between two groups,there were no differences in preoperative systolic pressure (P =0.245),the rate of TIMI flow 3 (P =0.568) after PPCI and ST segment resolution (P =0.824),LVEF (P =0.275) and in-hospital mortality (P =0.502).Compared with tirofiban group,the systolic pressure was lower and the rate of using intra-aortic counter-pulsation was higher in control group.Although the incidence of slight bleeding in the control group was lower than that in the tirofiban group,no severe bleeding was observed in both groups.Conclusions The effect of intracoronary use of tirofiban was similar to that of nitroglycerol in terms of improving slow flow of coronary artery.It could safely and effectively reduce the incidence of the coronary slow flow in the patients after PPCI,but it produced a little impact on systolic pressure.It may be a better method of choice for AMI patient with low blood pressure.

Thanks to the three decades of reform and opening up,hospitals in China have made tremendous achievements in their development,yet facing new ehallenges as well.to address these challenges,there is an urgent need for these hospitals to further their reform under the guideline of the scientific concept of development.This will help them strengthen their hospital culture,quality control,technology,human resources development,and their leadership,in order to achieve a better and faster growth,better serving the role to build a harmonious socialist society.

Objective To investigate the effects and the migration mechanisms of stromal derived factor-1 (SDF-1) and CXC chemokine receptor-4 (CXCR-4) in rats with white matter damage treated with human umbilical cord mesenchymal stem cells (hUC-MSCs).Methods A total of 108 three-day old Sprague-Dawley rats were randomly divided into the experimental group,control group and sham group.The left common carotid artery was ligated and then exposed to hypoxia of 6％ O2 and 94％ N2 in rats in the experimental and control groups.Rats in sham group were neither ligation nor hypoxia.After 24 hours,rats in the experimental group were administered 0.5 ml hUC-MSCs (1 × 106/ml) intraperitoneally,and rats in control and sham groups were administered 0.5 ml saline by the same way.Immunohistochemistry and reverse transcription-polymerase chain reaction were used to determine the expression of SDF-1 and CXCR-4 protein and mRNA in 5-,7-and 14-day-old rats.Analysis of variance and the LSD test were used for statistical analysis of the data.Results HE staining showed that,in 14 day-old rats of the experimental group,bilateral cerebral ventricles were similar with no cellular edema or necrocytosis.In the sham group,bilateral cerebral ventricles were also normal.However,in the control group,ventriculomegaly,cellular degeneration and necrocytosis were observed on the left side.On the 5th,7th and 14th day,SDF-1 protein levels were 0.15±0.06,0.24±0.01 and 0.12±0.01,and CXCR-4 protein levels were 0.35±0.16,0.60±0.21 and 0.72±0.25,respectively,in the experimental group; SDF-1 protein levels were 0.13 ± 0.01,0.16± 0.01 and 0.08± 0.01,and CXCR-4 protein levels were 0.18 ± 0.04,0.17 ± 0.09 and 0.25 ± 0.06,respectively,in the control group,and all were higher than those in the sham group (SDF-1 protein levels were 0.03 ± 0.01,0.04± 0.01 and 0.02±0.01; and CXCR-4 protein levels were 0.04±0.02,0.05±0.03 and 0.05±0.03,respectively) (LSD test,all P＜0.05).SDF-1 protein increased to a peak on the 7th day and decreased on the 14th day in the experimental group,however,these values were both higher than those in the control group (LSD test,both P＜0.05).CXCR-4 protein increased on the 5th day and continued to increase up to the 14th day in the experimental group,and these values were higher than those in the control group at the three time points (LSD test,all P＜0.05).In 5-,7-and 14-day-old rats,SDF-1 mRNA levels were 3.52 ± 0.33,4.18± 0.28 and 2.60± 0.21,respectively,in the experimental group,which were higher than those in the control group (2.07± 0.34,3.73 ± 0.28 and 2.08± 0.15,respectively),and were even higher than those in the sham group (0.99±0.17,1.00±0.16 and 1.31 ±0.32,respectively) (LSD test,all P＜0.05).In the experimental group,SDF-1 mRNA levels reached a peak on the 7th day,and on the 14th day,it decreased to the level lower than that on the 5th day (LSD test,all P＜0.05).In the control group,SDF-1 mRNA levels also reached a peak in 7-day-old rats,but not in 14-day-old rats,which was similar to 5-day old rats (LSD test,9＞0.05).In 5-,7 and 14-day-old rats of the experimental group,CXCR-4 mRNA levels were 1.32±0.29,1.75±0.36 and 2.33±0.49,respectively,higher than those in the sham group (1.00±0.16,0.94±0.16 and 0.81±0.14,respectively) and the control group (0.97±0.14,0.97±0.15 and 1.07±0.25,respectively) (LSD test,all P＜0.05).In the experimental group,CXCR-4 mRNA levels were higher in 14-day-old rats than that in 5-and 7-day-old rats (LSD test,both P＜0.05).Conclusions SDF-1/CXCR-4 may play a vital role in the migration of hUC-MSCs homing to damaged brain.
