Objective To investigate the effect of body mass index on early postoperative clinical outcomes following off-pump coronary artery bypass grafting. Methods A total of 1062 patients that received OPCABG in Beijing Anzhen Hospital were recorded continuously from January 2015 to May 2015. The patients were divided into normal weight group(n=360), overweight group(n=527) and obesity group(n=175) according to their body mass index. The following outcomes in the ear-ly postoperative period were compared among the three groups: hospital mortality, atrial fibrillation and intra aortic balloon counter pulsation usage, multiple organ failure score system, postoperative score for cardiac surgery, sequential organ failure assessment score, respiratory index, and pressure-adjusted heart rate. Results The lowest mortality rate was observed in the overweight group(0.6％) in comparison with the normal weight group(2.2％) and obesity group(1.1％)(P<0.01). The lowest rate of atrial fibrillation was observed in the obesity group(20. 1％) in comparison with the normal weight group (22.1％) and overweight group(20. 7％)(P <0. 01). The IABP usage rate was the highest in the normal weight group (8. 1％), followed by the overweight group(6. 0％) and the obesity group(2. 9％)(P<0. 01). On the operation day and the first day after operation, the MODS, SOFA and PSCS scores of the obese group were significantly higher than those of the nor-mal weight group(P <0. 01). PaO2/FiO2 in the obese group was significantly lower than that in the normal weight group (P<0. 01). PAHR in the obese group was significantly higher than that in the normal weight group(P<0. 01). Conclusion High BMI groups were associated with lower rates of mortality, atrial fibrillation, and IABP utilization. The lowest mortality rate was observed in the overweight group.

Objective:To summarize the experience of reoperation for 23 cases of cardiac myxoma recurrence.Methods:From January 2002 to December 2018, 1106 patients with cardiac myxoma underwent surgical treatment. Among them, 23 patients underwent reoperation after recurrence. 10 males and 13 females with an average age of (50.5±10.8) years old. There were 22 patients with secondary operation and 1 patient with four operations. 3 cases with mitral insufficiency and 1 case with tricuspid insufficiency. There were 20 patients with NYHA Ⅰ-Ⅱ and 3 patients with Ⅲ-Ⅳ. A total of 1 083 patients with cardiac myxoma undergoing primary operation were selected as the control group. The operation time, cardiopulmonary bypass time, aortic clamping time, ICU monitoring time, ventilator assisted breathing time, postoperative hospital stay, in-hospital mortality and cardiac ejection fraction at discharge were compared between the two groups.Results:8 cases (34.8%) had the first onset in the left atrial septum, and 15 cases (65.2%) in other parts. Recurrence site: left atrium in 17 cases(73.9%), left ventricle in 2 cases (8.7%), right atrium in 3 cases (13.0%), right ventricle in 1 case (4.3%). Reoperation accounted for 2.1% of cardiac myxoma surgery in the same period. The median recurrence time of 13 patients was 24 months. During the same period, mitral valve replacement was performed in 2 cases, mitral valvuloplasty in 1 case and tricuspid valve plasty in 1 case. The average operation time was (3.9±2.8) h, cardiopulmonary bypass time was (107.6±33.8) min, aortic clamping time was (64.9±23.8) min, ICU monitoring time was (20.1±16.0) h, ventilator assisted breathing time was (16.9±8.5) h, cardiac ejection fraction at discharge was 0.51±0.10, postoperative hospital stay was (8.3±1.5) days. The median follow-up time was 5 (1-18) years. One case (4.3%) died of all causes. There was no significant difference in ICU monitoring time, ventilator assisted breathing time, discharge cardiac ejection fraction, postoperative hospital stay and hospital mortality between reoperation patients and one operation ( P>0.05). Conclusion:Atypical cardiac myxoma has a high recurrence tendency after operation. Regular follow-up after the first operation of cardiac myxoma is a necessary means to early detect recurrence and avoid complications. Reoperation after recurrence can still achieve satisfactory results.

As a method for local treatment, radiotherapy plays a key role in the management of tumors. In the past few decades, great progress has been made in radiotherapy technology, with improvements in conformity, homogeneity, and radiotherapy efficiency, and the results are encouraging. Nevertheless, the maximum tolerated dose of normal tissue has limited the further increase in radiotherapy dose in the tumor area. If radiation-induced toxicities can be reduced, a higher radiotherapy dose can be delivered to tumor tissue, so as to achieve a better treatment response. In recent years, the unique FLASH effect of ultra-high-dose-rate radiotherapy (FLASH-RT) is capable of maintaining a consistent tumor response whilst reducing radiation-induced toxicities in normal tissue, and therefore, FLASH-RT has become a research hotspot in the field of radiotherapy across the world. At present, some scholars tend to explain the FLASH effect using the theory of acute oxygen depletion, but the protective effect of FLASH-RT on normal tissue remains to be clarified. In addition, preliminary clinical studies have been conducted for FLASH-RT, and the results are promising. Based on existing evidence, this article elaborates on the research advances in FLASH-RT in the treatment of malignant tumor, so as to provide a reference for the translation and application of this new technique.

Objective: To analyze the clinical efficacy of coronary artery bypass grafting(CABG)in patients of advanced age with left main coronary artery disease(LMCAD). Methods: From 2005 to 2014, 101 elderly patients(≥80 years)with LMCAD underwent off-pump CABG in our hospital.Among them, 82 were male and 19 were female, with an average age of(81.4±1.7)years.Seventy-six cases(75.2%)had significant left main stenosis(≥70%)and twenty-five cases had left main stenosis less than 70%.The average left ventricular end diastolic diameter was(48.2±8.3)cm; left ventricular ejection fraction was more than 50% in 89 cases and 30% to 50% in 12 cases.Fourteen cases had mitral insufficiency and one had ventricular aneurysm.In addition, 56 patients had New York Heart Association functional classification Ⅰ to Ⅱ, and 45 patients had classification Ⅲ to Ⅳ.Ninety-nine patients had Canadian Vascular Society(CCS)classification of angina pectoris Ⅰto Ⅲ, two had classification Ⅳ and thirteen had acute myocardial infarction.Six patients were implanted with intra-aortic balloon counterpulsation before CABG. Results: The average operation time was(3.9±0.8)h, the average number of bridging vessels were(3.0±1.0)roots, ICU monitoring time was(50.2±46.0)h, and ventilator assisted breathing time was(42.9±68.5)h.Six patients(5.9%)had secondary thoracotomy hemostasis, five(4.9%)had secondary tracheal intubation, and four(4.0%)had continuous dialysis.Intra-aortic balloon counterpulsation was implanted in 3cases(2.9%)during operation and in 11 cases(10.9%)after operation.Two cases(2.0%)had perioperative myocardial infarction and 8 cases(7.9%)died after operation during hospitalization.The median follow-up time was 6(1-11)years, and 17(16.8%)had all-cause mortality. Conclusions Although the two independent high-risk factors, old age and left main stenosis often coexist, off-pump CABG and perioperative management are still safe and effective treatments.

Objective: To investigate the effect of different mechanisms of liver-protection drugs in clinic and compare which one is best for the proliferation of irradiated HL-7702, laying the basis of liver-protection drugs choose in clinic on theory and practice. Methods: Human liver parenchyma cells HL-7702 were given single 6 MV X ray irradiation at a dose of 10Gy, the cells’ morphology were detected under an inverted microscope at 24h, 48h and 72h. Then, MTT was used to assess the survival rate of the cells to evaluate the effect of the X ray. The representive medicines which mechanism may relate to RILD were chosen and diluted into various concentrations with culture medium according to clinical and relative reports. Different concentrations of medicines were used to protect the cells damaged by the X ray. Comparing the effect with MTT and measure SOD, MDA for the best one. Further research on its protection of oxidative damage. T-test, F test and non- paramiter test were used for statistical analysis. Results: 2.5 mg/ml and 1 mg/ml of magnesium isoglycyrrhizinate both have an effect on the proliferation of liver cells, especially the concentration of 1 mg/ml. The injection of polyene phosphatidyl choline show trivial effect at the concentrations of 250 μmol/L and reduced glutathione(GSH) did not demonstrate relative functions. Further research on the magnesium isoglycyrrhizinate, found its protection at 48h to oxidative damage (P < 0.05), but the effect is weak at 24h and 48h. Conclusions In three kinds of representing medicines, magnesium isoglycyrrhizinate has preferable effects on liver parenchyma cells and show a bright future in the treatment of RILD.

Objective:To investigate the difference between the short-term and long-term survival rates of patients undergoing tricuspid valve replacement with biological and mechanical valves.Methods:273 patients who received tricuspid valve replacement were selected from our Hospital from November 1993 to August 2018. The mean follow-up time was(8.2±5.6) years. The total follow-up rate was 95%. Kaplan-Meier method was used to make survival curves of the two groups and log rank test was used to compare the differences between the two groups. In addition, this study made the comparison of preoperative, intraoperative and postoperative information and long-term survival rate between these two groups.Results:There was no significant difference in demographic characteristics and baseline between mechanical valve group and biological valve group. 16 patients died in the mechanical valve group and 22 in the biological valve group. In the mechanical valve group, 14 cases died of postoperative low cardiac output syndrome and 2 cases died of gastrointestinal hemorrhage. 22 patients were died of low cardiac output syndrome. The auxiliary time in the mechanical valve group was longer than that in the biological valve group[(151.76±70.30)min vs.(131.62±60.25)min, P=0.013)]. There was no significant difference in long-term survival rate between the two groups in Kaplan- Meier survival curve( P=0.234). Conclusion:There is no difference in short-term and long-term survival rate between mechanical valve and biological valve in tricuspid valve replacement.

Objective     To summarize the clinical characteristics and surgical treatment experience of 1 106 patients with cardiac myxoma. Methods     Clinical data of 1 106 patients with cardiac myxoma who underwent surgical treatment in Beijing Anzhen Hospital from 2002 to 2018 were retrospectively analyzed. There were 749 (67.7%) females and 357 (32.3%) males. Results     The highest incidence rate was at the age of 51-70 years. The location of the disease was: left atrium in 987 (89.2%) patients, right atrium in 99 (9.0%) patients, left ventricle in 10 (0.9%) patients, right ventricle in 8 (0.7%) patients. There were 1 013 patients of heart classification (NYHA) Ⅰ-Ⅱ and 93 patients of Ⅲ-Ⅳ. There were 301 patients with cerebral infarction and 57 patients with peripheral arterial embolism. Tumor size was closely related to hemodynamic symptoms (P≤0.05), but not to peripheral vascular embolism (P>0.05). Two (0.2%) patients died in hospital and 306 patients were followed up, with a follow-up rate of 27.7%. The median follow-up time was 7 years (range, 1-18 years). One patient died of all causes, and 23 patients recurred, with a recurrence rate of 2.1%. Among 23 recurrent patients, 15 (65.2%) patients were atypical myxoma and 8 (34.8%) patients were typical myxoma. There was no statistical difference in aortic clamping time, ICU stay time, ventilator-assisted breathing time, postoperative hospital stay time, postoperative mortality, or cardiac ejection fraction at discharge between the reoperation in 23 recurrent patients and the first operation in 1 083 non-recurrentpatients. Conclusion     Cardiac myxoma is more common in middle-aged and elderly women, and it often occurs in the left atrium. The size of cardiac myxoma can affect the hemodynamic changes. Surgical treatment is effective. Atypical myxoma is more common in recurrent patients, and the effect is still satisfactory through surgical treatment.
