Objective:To explore the clinical effect of different surgical methods combined with Neoadjuvant chemotherapy in treating patients with breast cancer.Methods:80 patients treated and diagnosed in our hospital from January,2012 to January,2014 were enrolled in the present study.According to the willingness,physical condition and financial situation,they were divided them into group A (23 cases) and group B (57 cases).Neoadjuvant chemotherapy of EC regimens (epirubicin+cyclophosphamide) was applied to both groups,on the basis of which,group A received breast-conserving surgery,group B received modified radical mastectomy.The clinical effect,breast cosmetic result,life quality,psychological states were compared in both groups.Results:The operation time,extubation time were significantly shorter than those of group B (p ＜0.05),the amount of bleeding,AMA,HRSD score,occurrence rate of complications in group A were significantly lower than those of group B (p＜0.05),the breast cosmetic result of group A was obviously better than that of group B (p＜0.05),and the QLQ-BR23 score in group A was significantly higher than that of group B (p＜0.05).The 2-year survival rate and 2 year recurrence rate showed no statistical difference between the two groups (p ＞0.05).Conclusion:Breast-conserving surgery combined with epirubicin neoadjuvant chemotherapy was effective in treating breast cancer,which could decrease the complications,improve the breast cosmetic result and quality of life.

Objective To investigate the effects of sevoflurane postconditioning on myocardial ischemiareperfusion(I/R)injury in patients undergoing coronary artery bypass grafting(CABG)with cardiopulmonary bypass(CPB).Methods Forty NYHA Ⅰ -Ⅲ patients of both sexes,aged 55-64 yr,with BMI ＜ 30 kg/m2,scheduled for CABG under CPB,were randomly divided into 2 groups(n = 20): control group(group C)and sevoflurane postconditioning group(group S).Anesthesia was induced with midazolam and/or etomidate,fentanyl and rocuronium.Patients were tracheal intubated and mechanically ventilated.Anesthesia was maintained with iv infusion of propefol and intermittent iv injection of fentanyl and pipecuronium.In group S,2% sevoflurane was inhaled continuously for 15 min immediately after aortic unclamping.After anesthesia induction,before CPB,10 min after the end of CPB,at the end of operation,and 6 and 24 h after operation,MAP,HR,CVP,mean pulmonary arterial pressure,pulmonary arterial wedge pressure,CO and S(v)O2 were recorded,and CI,SVI,systemic vascular resistance index and pulmonary vascular resistance index were calculated.Blood samples were taken from central vein before aortic clamping,at 6 h of reperfusion and 24 h after operation for determination of plasma creatine kinase(CK),creatine kinase isoenzyme(CK- M B)and lactate dehydrogenase(LDH)activities and tropenin I(TnI)concentrations.Myocardial tissues were obtained from right auricle before aortic clamping and at the end of CPB for observation of the ultrastructure and the severity of myocardial injury was assessed.Results There was no significant difference in hemodynamics and parameters of cardiac function between the two groups(P ＞ 0.05).Compared with group C,plasma CK-MB and LDH activities at 6 h of reperfusion and plasma CK activity and TnI concentrations at 24 h after operation were significantly decreased and the myocardial injury was significantly reduced after the end of CPB in group S(P ＜ 0.05).Conclusion Sevoflurane postconditioning can protect myocardium against I/R injury induced by CPB in patients undergoing CABG.

Objective Summarizing single clinical experience with extracorpomreal membrane oxygenation(ECMO) as a supplement to extracorporeal cardiopulmonary resuscitation(ECPR) in adult patients with cardiac arrest to explore new ideas.Methods We retrospectively analyzed the characteristics of 17 patients who underwent ECMO as part of ECPR from July 2005 to September 2014 at Fuwai Hospital,and analyzed the differences between the survival group(n =6) and the in-hospital death group.Results The mean CPR time was(44.53 ± 21.39) min.The support duration of ECMO was(106.38-± 70.43) h.12 patients of all were successfully weaned from ECMO,and 6 patients survived to hospital discharge.There were significant differences between the two groups in terms of the last serum creatinine and blood lactate acid level before ECMO,and the time to lactate normalization.11 patients died,7 patients developed bleeding,and 8 cases developed infection.Conclusion Single-center data showed that applying ECMO as a means of ECPR improved the survival rate in cardiac arrest patients.Additionally,creatinine and lactic acid were good indicators for assessing prognosis.Refractory circulatory dysfunction and neurologic complications have an adverse impact on the survival of cardiac arrest patients.

Objective:To study the efficacy of three-dimensional (3D) CT reconstruction combined with 3D color printing compared with traditional imaging technology in treatment of complex hepatobiliary calculi treated with laparoscopy and choledochoscopy.Methods:A retrospective study was conducted on 128 patients with complex hepatobiliary calculi who underwent hepatobiliary surgery at the Qingdao Chengyang People’s Hospital, Qingdao Municipal Hospital Affiliated to Qingdao University and Qingdao University Affiliated Hospital from January 2019 to December 2019. A comparison was made between patients who underwent three-dimensional CT reconstruction combined with 3D color printing (the study group, n=62) and the traditional imaging technology group (the control group, n=66) on operation time, intraoperative blood loss, liver blood flow occlusion time, stone clearance rate, postoperative complication rate, and recurrence of calculi after operation. Results:The study group was significantly better than the control group in operation time, intraoperative blood loss, porta hepatis occlusion time, hospital stay and treatment cost (all P<0.05). The stone clearance rate of the study group was 96.8% (60/62), which was significantly higher than that of the control group (86.4%, 57/66) ( P<0.05). The incidence of postoperative complications in the study group was 3.2% (2/62), which was significantly lower than that in the control group (18.2%, 12/66) ( P<0.05). There was no significant difference in the stone recurrence rate between the two groups (all P>0.05). Conclusion:Three-dimensional CT reconstruction combined with 3D color printing contributed significantly to the surgical treatment of complex intrahepatic bile duct stones as these imaging technologies significantly improved surgical accuracy, improved stone clearance and reduced postoperative complication rates, and reduced surgical treatment costs.

Objective: To investigate theperiodic changes in onset of aortic dissection. Methods: The clinical data of 1 121 patients with acute aortic dissection from Hebei province, treated at Fuwai hospital from January 1, 2010 to December 31, 2016, were collected and analyzed retrospectively. The regularity for the onset of aortic dissection was analyzed according to daytime (1:00 to 6:00, 7:00 to 12:00, 13:00 to 18:00, and 19:00 to 24:00), weekday, month, and quarter. Meanwhile,the differences in various type of aortic dissection patient were also compared. Results: The patients were (51.4±12.0) years old,77.88% (873 cases)were male and 69.05% (774 cases) were type A aortic dissection.The peak period for the onset of the disease in a day was from 13:00 to 18:00 (401 cases. 35.77%),and disease onset was less frequent from 1:00 to 6:00 (196 cases, 17.48%).The peak weekday of disease onset was Monday (173 cases, 15.43%) , and disease onset was less frequent on Friday (153 cases, 13.65%) . The peak month of disease onset was January (135 cases, 12.04%), and disease onset was less frequent in July(54 cases, 4.82%). The peak season of disease onset was winter (349 cases, 31.13%), and disease onset was less frequent in summer (184 cases, 16.41%). Number of disease onset was similar between ≥65 years old and<65 years old groups, with or without hypertension groups, with or without Marfan syndrome groups at different periods of a day, each weekday, and seasons(all P>0.05). Conclusion There are periodic changes in the onset of acute aortic dissection,which is higher in winter than in summer, higher in the afternoon than in the morning.

Objective To observe the incidence of spinal cord injury (SCI) following aortic surgery in Fuwai Hospital of Chinese Academy of Medical Sciences, and evaluate the effect of standardized multidisciplinary spinal cord protection strategies, to summarize the experience in the prevention and treatment of SCI at perioperative period of aortic surgery. Methods The clinical data of patients underwent aortic surgery admitted to vascular center of Fuwai Hospital from January 2011 to December 2018 were retrospectively analyzed. The patients receiving traditional spinal cord protection strategies from January 2011 to December 2016 were defined as the control group, while the patients receiving standardized multidisciplinary spinal cord protection strategies from January 2017 to December 2018 were defined as the standardized treatment group. The standardized multidisciplinary treatment included preoperative cerebrospinal fluid drainage (CSFD), respiratory tract management, and maintenance of effective circulation of the lowest venous pressure; at the same time, anticoagulation, glucocorticoid, improve microcirculation, scavenge oxygen free radicals and other adjuvant treatments were started, and nerve function was monitored to prevent complications. The changes in SCI incidence after aortic surgery between the two groups were observed in order to evaluate the effect of standardized multidisciplinary spinal cord protection strategies. Meanwhile, the types of SCI after operation and the safety of CSFD were analyzed. Results During the 8-year period, 7 724 patients underwent aortic surgery at vascular center of Fuwai Hospital, 64 of which suffered from SCI after aortic surgery with total incidence of 0.83%. The onset of SCI was immediate in 39 patients (60.94%) and was delayed in 25 patients (39.06%), more than half of patients were immediate SCI. Of 64 patients with SCI, 52 patients (81.25%) underwent paraplegia and 12 (18.75%) underwent paraparesis. SCI persisted beyond discharge in 38 patients (59.38%) and 25 patients (39.06%) fully or partly recovered form SCI. One patient (1.56%) died. Compared with the control group, the incidence of SCI was decreased significantly after application of standardized multidisciplinary spinal cord protection strategies. The total incidence of SCI after aortic surgery was decreased from 1.06% (52/4 893) to 0.42% (12/2 831), the incidence after aortic arch replacement under deep hypothermic circulatory arrest was decreased from 3.66% (40/1 092) to 1.11% (5/450), and the incidence after thoraco-abdominal aortic replacement was decreased from 9.40% (11/117) to 2.47% (2/81) with statistically significant difference (all P < 0.05). Perioperative CSFD analysis showed that the incidence of CSFD-related complications was low, the overall incidence was 5.45% (3/55), including 1 patient of cerebrospinal fluid leakage, 2 patients of blood cerebrospinal fluid. No serious complications such as hemorrhage and infection of central nervous system occurred. Conclusions The main type of SCI after aortic surgery was immediate, about 39% SCI patients fully or partly recovered. Standardized multidisciplinary spinal cord protection strategies which included preoperative CSFD, reduced incidence of SCI after aortic surgery. The incidence of CSFD-related complications was low, which was safe and effective.

Objective    To discuss the efficacy of type Ⅱ hybrid aortic arch repair for type A aortic dissection in patients of different age groups. Methods    We retrospectively analyzed the clinical data of 126 patients with type A aortic dissection admitted to the Fuwai Hospital between January 2016 and December 2018, including 78 (61.9%) males and 48 (38.1%) females, with an average age of 61.8±6.9 years. The patients were divided into an elderly group (≥60 years, n=82) and a non-elderly group (<60 years, n=44). The preoperative, intraoperative and postoperative data of patients in the two groups were compared. Results    The age between the elderly and non-elderly group was significantly different (65.9±4.1 years vs. 54.3±4.1 years, P<0.010), and no significant difference was found between the two groups in other preoperative baseline data. There were 6 (4.8%) patients of early death, 3 (2.4%) patients of stroke and 2 (1.6%) patients of paralysis. A total of 194 stents were implanted, and the average dimeter of the stents was 33.6±1.8 mm and the average length was 199.0±6.7 mm. The non-elderly group had shorter mechanical ventilation time (31.9±41.7 h vs. 61.0±89.2 h, P=0.043) and ICU stay time (77.8±51.4 h vs. 143.1±114.4 h, P<0.001) than the elderly group. There was no significant difference in in-hospital mortality rate, reoperation rate or survival rate between the two groups (P>0.05). Follow-up time was 1-43 (22.6±10.8) months, and 3 patients were lost. There were 104 (82.5%) patients of complete thrombus formation of false lumen in stent and endoleak was reported in 11 (9.2%) patients. Conclusion    Type Ⅱ hybrid aortic arch repair offers an alternative approach to acute type A aortic dissection with acceptable early and mid-term clinical effects. The non-elderly patients have a similar early treatment effect to the elderly patients, but have a better mid-term outcome.

Objective     To investigate predictors for mortality among patients with Stanford type A acute aortic dissection (AAD) and to establish a predictive model to estimate risk of in-hospital mortality. Methods     A total of 999 patients with Stanford type A AAD enrolled between 2010 and 2015 in our hospital were included for analysis. There were 745 males and 254 females with a mean age of 49.8±12.0 years. There were 837 patients with acute dissection and 182 patients (18.22%) were preoperatively treated or waiting for surgery in the emergency department and 817 (81.78%) were surgically treated. Multivariable logistic regression analysis was used to investigate predictors of in-hospital mortality. Significant risk factors for in-hospital death were used to develop a prediction model. Results     The overall in-hospital mortality was 25.93%. In the multivariable analysis, the following variables were associated with increased in-hospital mortality: increased age (OR=1.04, 95% CI 1.02 to 1.05, P<0.000 1), acute aortic dissection (OR=2.49, 95% CI 1.30 to 4.77, P=0.006 1), syncope (OR=2.76, 95% CI 1.15 to 6.60, P=0.022 8), lower limbs numbness/pain (OR=7.99, 95% CI 2.71 to 23.52, P=0.000 2), type Ⅰ DeBakey dissection (OR=1.72, 95% CI 1.05 to 2.80, P=0.030 5), brachiocephalic vessels  involvement (OR=2.25, 95% CI 1.20 to 4.24, P=0.011 7), acute liver insufficiency (OR=2.60, 95% CI 1.46 to 4.64, P=0.001 2), white blood cell count (WBC)>15×109 cells/L (OR=1.87, 95% CI 1.21 to 2.89, P=0.004 9) and massive pericardial effusion (OR=4.34, 95% CI 2.45 to 7.69, P<0.000 1). Based on these multivariable results, a reliable and simple bedside risk prediction tool was developed. Conclusion     Different clinical manifestations and imaging features of patients with Stanford type A AAD predict the risk of in-hospital mortality. This model can be used to assist physicians to quickly identify high risk patients and to make reasonable treatment decisions.
