ABSTRACT
Objective:Based on the statistical data of the comprehensive evaluation of professional degree graduate students by the guiding physicians, to conduct an empirical study on the quality of the enrollment of master of stomatology professional degree graduate students.Methods:A total of 67 master of stomatology professional degree graduate students from Shanghai Ninth People’s Hospital, Shanghai Jiao Tong University were comprehensively evaluated by their guiding physicians when they went out the department. SPSS 25.0 software was used for t test and variance analysis. Results:The average score of 67 students was (91.39±3.55) points. There was good reliability and validity for the comprehensive evaluation index. Among the methods of promotion and exemption, unified examination, 7-year transfer to "5 + 3" of our school and enrollment of students from Hong Kong, Macao and Taiwan regions, the comprehensive evaluation total score of 7-year transfer to "5 + 3" of our school was the highest. The comprehensive evaluation results of the students with high initial scores were slightly higher than those students with low scores. The students who studied in the "Double First-class" universities and were with the fourth round of subject assessment grade A and grade B had better performances.Conclusion:We should attach importance to enrollment quality, through various channels to attract quality students and actively explore ways to improve the quality of graduate students. Meanwhile, we should make efforts to strengthen training quality and to build scientific comprehensive evaluation system for specialized degree graduate students. The connotation of "medicine-education collaboration" will be further deepened. And the training and development of oral medicine applied high-level medical talents will be promoted.

ABSTRACT
Objective@#To investigate the heart rate control situation of chronic heart failure (CHF) patients who received cardiovascular implantable electronic device (CIED) therapy, and to assess the heart rate control efficacy by optimized medication adjustment.@*Methods@#We performed a perspective study in heart failure with reduced left ventricular ejection fraction (HFrEF) patients who received CIED according to guideline recommendations, patients were enrolled from January 2012 to January 2017. Resting heart rate (RHR) recorded by electrocardiogram after 10 minutes' rest and medication usage within 1 month were recorded at baseline. RHR less than 70 beats per minute (bpm) was regarded as well controlled. β-receptor blockers and (or) ivabradine would be added in patients whose RHR were over 70 bpm. RHR after optimized medication adjustment was recorded during follow-up period.@*Results@#One hundred and fifty patients were included in this study with average RHR (80.6±11.9) bpm. RHR was<70 bpm in 27.3% (41/150) patients at baseline and β-receptor blockers was underused in 80.7% patients (88/109) whose RHR was>70 bpm. The overall RHR decreased to (73.1±10.4) bpm and percent of patients with RHR<70 bpm increased to 70.0% (105/150) after up-titration of β-receptor blockers compared to baseline (χ2=52.958, P<0.001). Ivabradine was added in the rest 45 patients and RHR was<70 bpm in 43 out of 45 patients after ivabradine use. The overall RHR decreased to (67.1±2.7) bpm and percent of RHR<70 bpm significantly increased to 98.7% (148/150) (χ2=44.504, P<0.001 vs. up-titration of β-receptor blockers only).@*Conclusion@#RHR in CHF patients who received CIED therapy is not ideally controlled in this patient cohort, individual up-titration ofβ-receptor blockers and ivabradine use may help to optimize RHR in these patients.
ABSTRACT
Objective To understand the effect of standardized training teachers for fellowship training and to summarize the experience, in order to provide practical basis for standardized training of fellowship training and teachers training. Methods According to the requirements of standardized training for fellowship in Shanghai, the content of teacher training is drawn up. The training lasts for 4 days and 32 academic hours. After the training, 317 questionnaires were distributed through the form of electronic ques-tionnaire, and 301 questionnaires were recovered, with a recovery rate of 94.95％. Data statistics are in EXCEL (2016), and the data are expressed as percentage. Results Teachers participating in the training believe that fellowship training should pay most attention to the training of clinical operation skills and clin-ical thinking ability. Teachers have a high demand for training related to fellowship training policies, teach-ing ability, training quality control, teachers' professional quality and other aspects. The most popular teach-ing methods are teaching observation and discussion in small classes. 288 teachers (95.69％) thought that the teacher training was very effective or good, and 290 teachers (96.55％) thought that the teacher training would be very helpful or helpful to the future fellowship training and teaching work. Conclusion This teachers training has achieved good results. In the future, stratified and specialized training can be carried out to further improve the pertinence of teachers training. At the same time, we should strengthen the man-agement of the special training process and consolidate the special training quality. We will improve the evaluation methods and test the results.

Objective To investigate the influence of high frequency electrosurgical equipment ( HFEE) application in cardiac implantable electronic device ( CIED) implantation procedure on the rate of pocket hematoma .Methods Patients who received CIED implantation in General Hospital of Shenyang Military Region were analyzed retrospectively .HFEE was applied during CIED implantation procedure in every patient who was classified into HFEE group .Other patients without HFEE application were classified as the control group . Patients with or without bleeding tendency were sub-classified into the bleeding tendency subgroup or non-bleeding tendency subgroup respectively .Bleeding tendency subgroup was further divided into heparin bridging group and direct implantation group .The occurance rate of CIED pocket hematoma was recorded in all groups .Results A total of 3884 patients were enrolled .There were 3115 patients in the HFEE group and 769 patients in the control group .The baseline data of two groups was similar.The overall rate of CIED pocket hematoma in the total patient population during perioperative period were 2.2%(86/3884), and the rate of long term pocket infection or rupture in patients with CIED pocket hematoma was 10.5%(9/8).In the HFEE group, the rate of pocket hematoma was lower than that in the control group (1.5%vs.5.2%, P<0.001).The rates of CIED pocket hematoma in respective subgroups in the HFEE group including the bleeding tendency subgroup ( 1.8% vs.11.5%, P=0.004 ) , the non-bleeding tendency subgroup ( 1.4% vs.4.7%, P<0.001 ) and the heparin bridging group ( 2.0% vs. 11.5%, P=0.046 ) were markedly decreased as compared with the corresponding subgroups in the control group.In the control group , the rate of CIED pocket hematoma in the bleeding tendency subgroup was higher than that in the non-bleeding tendency subgroup (11.5%vs.4.7%, P=0.0046).In HFEE group, there was no significant difference in the rate of CIED pocket hematoma between bleeding tendency subgroup and non-bleeding tendency subgroup; and there was also no significant difference in the rate of CIED pocket hematoma between the heparin bridging group and the direct implantation group .Conclusion Application of HFEE in CIED implantation procedure could reduce the incidence of pocket hematoma , and there was no significant difference in the incidence of pocket hematoma in patients with or without oral anticoagulation or antiplatelet agents.
ABSTRACT
Objective Acute respiratory dysfunction (ARD) can occur after aortic surgery with the use of cardiopulmonary bypass and deep hypothermic circulation arrest, but relatively little is known about acute respiratory dysfunction in the patients with type A aortic dissection. This study aims to analyze the independent risk factors of acute respiratory dysfunction after A type aortic dissection surgery and to assess possible prevention and treatment option in the future. Methods Clinical data of the 252 patients including 193 male patients and 59 female patients who underwent type A aortic dissection surgery from February 2009 to October 2010 were collected. The mean age was 47 years. Postoperative acute respiratory dysfunction was defined as oxygenation impairment (PaO2/FiO2 ＜ 150) that occurred within 72 h of surgery except pleural effusion, cardiogenic pulmonary edema, pneumonia, pulmonary embolism and haemato-/ pneumothorax. There were 187 acute A type aortic dissection patients and 65 chronic type A aortic dissection patients. Clinical characteristics including age, gender, weight, height, history of hypertension, history of smoking, preoperative complications such as preoperative shock and acute renal failure, pericardial effusion, previous cardiac surgery, time from event to surgery, malperfusion syndrome, cardiopulmonary time, cross-clamp time,deep hypothermia circulation arrest time, surgical procedure, duration of intensive care unit stay and postoperative complications including tracheotomy, dialysis dependent renal failure and hospital mortality were gathered. Arterial blood analysis, chest X ray, ventilator parameters, number of blood transfusion and flood balance were assayed after operation. All the factors were evaluated by means of univariate and multivariate logistic regression analysis to identify relative risk factors of ARD. Results Acute respiratory dysfunction occurred in 32 (12.7% ) patients. The in-hospital mortality was significant difference between acute respiratory dysfunction group and non- acute respiratory dysfunction group (P ＜ 0.05). The value of BMI, incidence of acute aortic dissection, preoperative SBP level, cardio-pulmonary bypass time, aortic clamp time and total arch replacement in acute respiratory dysfunction group were significantly higher than the values in non- acute respiratory dysfunction group. Multivariate Logistic regression analysis showed blood transfusion more than 10 units and cardio-pulmonary bypass time more than 160 minutes were independent risk factors of early stage acute respiratory dysfunction after type A aortic dissection surgery.Conclusion Acute respiratory dysfunction after type A aortic dissection was a severe early stage postoperative complication and was associated with in-hospital mortality. The patients in acute aortic dissection were prone to have acute respiratory dysfunction. The independent risk factors of acute respiratory dysfunction included blood transfusion more than 10 units and cardio-pulmonary bypass time more than 160 minutes.
ABSTRACT
Objective The incidence of post-operative hyperbilimbinemia, which is associated with poor outcomes in patients, was reported to be increased in recent years though it has been a rare complication for cardiac operations. Post-opera-tive impairment of liver function is highlighted. We evaluated the incidence and prognosis of post-operative hyperbiliruhinemia in adult patients who underwent cardiotomy with extracorporeal membrane oxygenation (ECMO) support. Methods Sixty-five adult patients who had received ECMO support after cardiac surgery from 2004 to 2008 were enrolled and evaluated retrospec-tively. Post-oporative hypethilirubinemia was defined as the serum level of the total bilirubin more than 51.3 μmol/L during postoperative period. Demographic and clinical data included gender, age, types of surgery, perioperative hemodynamic param-eters, biochemical variables, duration of the ventilation support, ICU stay and outcomes. Results The mean age of the pa-tients was (50.1 ± 13.9) years, forty-six patients(70.8%) were male. The main cardiac procedures were heart transplanta-tion for 9 patients, coronary artery bypass grafting and/or valve operations for 47 patients, congenital heart disease correction for 4 patients and other operations for 5 patients. Among all patients, fifty-one patients(78.5%) were weaned from ECMO succeas-fully and thirty-thrce patients were discharged from hospital. The overall mortality rate was 49.2%. Overall incidence of post-operative hyperbilirubinemia was 55.4%. In patients with postoperative hyperbilirubinemia, the mean peak value for serum to-tal bilirubin was 104.8 (68.5-156.7) μmol/l. The hospital mortality in the hyperbilirubinemia group was significantly higher than that in the non-hyperbilirubinemia group(66.7% vs. 27.6%, P <0.01). Moreover, postoperative hypethilirubinemia (adds ratio = 3. 895, 95% confidence interval, 1.088 - 13.947 ; P = 0.037) and SOFA score (odds ratio = 1.214, 95% confidence interval, 0.987 - 1.494, P = 0.047) and APACHE Ⅲ score (odds ratio = 1.096, 95% confidence interval, 1.028 - 1.169 ; P = 0.004) were associated with hospital mortality after adjusting for preoperative levels of the total bilirubin, direct bilirubin, gender and age. Conclusion Postoperative hyperbilirubinemia is one of the complications in adult patients who undergo cardiotomy with ECMO support, and is associated with increased hospital mortality.
ABSTRACT
Objective To evaluate the value of acute kidney injury network (AKIN) criteria for predicting hospital mortality in post-cardiosurgery elderly patients. Methods From October 2006 to January 2007, the elderly patients who underwent coronary artery bypass grafting or valve replacement operation were enrolled in this study. The medical data included gender, age, operation type, perioperative hemodynamic parameters, urine output, biochemical parameters and outcome. Renal function was assessed according to the AKIN criteria, and severity of illness was determined after surgery by calculating Acute Physiology and Chronic Health Evaluation Ⅱ (APACHE Ⅱ ) score. Results A total of 225 patients underwent cardiac surgery during this period, 169 patients were male (75. 1%), while 56 were female (24. 9%), mean age was (66. 7±5. 0) years old. The overall hospital mortality rate was 5.8% (13/225). According to AKIN criteria, there were 125 patients with acute kidney injury (55.6%), and the hospital mortality of stage 1, 2 and 3 patients were 2. l%(2/96), 9. 1% (1/11) and 50. 0% (9/18) respectively. A significant increase was observed in mortality based on AKIN criteria (P<0. 01). By applying the area under the receiver operating characteristic curve, the AKIN criteria had a good discriminative power. Conclusions Both the incidence and mortality rate of acute kidney injury in the post-cardiosurgery elderly patients are high, the AKIN criteria is a simple and valuable method with a good prognostic capability for evaluating acute kidney injury.
ABSTRACT
Objective To summarize our experience with off-pump coronary artery bypass grafting (OPCAB) during previous 13 years. Methods Data from 3703 patients who underwent OPCAB between October 1996 and December 2008 were collected and analyzed in this study. Following perioperative variables were reviewed and evaluated: changes in the number of patients, demographic characteristics of patients, coexisting conditions such as hypertension, and diabetes, grafting options,numbers of grafts per patient, and postoperative complications and clinical outcomes. Patients were divided into four age subgroups: those who were less than 45 years were assigned to group 1, those who were 45 to 60 years were assigned to group 2,those who were 60 to 75 years were assigned to group 3, and those older than 75 years of age were assigned to group 4. Perioperative data, including the use of internal mammary artery and the constituent of the grafts, were collected retrospectively and analyzed. Results Three thousand and twenty-five patients were male (81.7%) and 678 were female ( 18.3% ), mean age was (61.35 ±9.38) years old. The number of patients who underwent OPCAB increased steadily over time. The mean grafts per patient were 3.3 ± 0.8. The use of left internal mammary artery and "hybrid" bypass grafts composed of vein and artery played a predominant role in this cohort (P<0.05) . During this period of 13 years, intra-aortic balloon counterpulsation (IABP)was performed in 41 patients and continuous renal replacement therapy (CRRT)was required in 12 patients. Main complications included rethoracotomy for bleeding and tamponade in 1.49% of patients, deep sternal wound infection requiring re-exploration in 1.38%, perioperative myocardial infarction in 1.03%, neurological adverse events in 0.62%, tracheotomy in 0.59%, acute renal dysfunction in 0.77%, and other complications in 0.77%. The overall in-hospital mortality was 0.7% (26 of 3703 patients). A trend toward a reduction in morbidity and mortality was shown in this study. Diseases associated with hospital mortality were cardiac sudden death, multiple organ dysfunction syndrome, low cardiac output syndrome, severe infection, extensive myocardial infarction and neurological adverse events. Conclusion The indications for OPCAB, an innovative revascularization strategy, have been expanded and the curative rate for OPCAB has been improved in recent years. Appropriate and practical grafting strategies, as well as complete perioperative management, are considered as contributors to the improved outcomes.
ABSTRACT
Objective Patients in the intensive care unit (ICU) are at high risk for multi-organ failure and death. Few well-established scoring systems have been used in the cardiac surgery. We try to identify a feasible score system for the risk assessment after CABG. Methods 1028 consecutive patients who had received CABG and staying in a single cardiac postoperative intensive care unit of Anzhen hospital were enrolled in the prospective study between October of 2007 and May of 2008 and assessed daily with three score systems, the multiple organ dysfunction score (MODS), the sequential organ failure assessment (SOFA) and our postoperative score for cardiac surgery (PSCS). Four new variances were added to PSCS system, which were Euroscore, IABP, ECMO and dialysis. Euroscore was considered as a preoperative factor which provided the preoperative information of the patient. IABP and ECMO were considered as assistant factors to support circulatory system. The dialysis was also considered as an assistant factor to support renal system. The differences with the respects of sensitivity and specificity among the three systems were compared with Hosmer-Lemeshow goodness-of-fit and receiver operating characteristic (ROC)curve. Results The new variances added to PSCS system were shown to be associated with mortality in a multivariate logistic regression analysis. The EXP(B) value for Euroscore was 3. 803, the EXP(B) value for IABP was 1. 645, the EXP(B) value for ECMO was 3.803, and the EXP(B) value for dialysis was 1.605. In discrimination analysis, ROC values of the operative day score were 0.602 for MODS, 0.571 for SOFA, and 0. 821 for PSCS; ROC values of the maximum score were 0.847 for MODS, 0.830 for SOFA, and 0.929 for PSCS; ROC values of the maximum score during the first 3 days were 0.838 for MODS, 0.814 for SOFA, and 0.919 for PSCS; score changes of ROC value between the third day and the first day were 0.767 for MODS, 0.779 for SOFA, and 0. 780 for PSCS. In calibration analysis, we compared the x2 values, P values and overall corrected percentage of the three different systems. x2 values of the three systems were 6. 763 for MODS, 4. 101 for SOFA, and 1.687 for PSCS; P values of the three systems were 0.454 for MODS, 0. 848 for SOFA, and 0. 975 for PSCS; overall corrected percentages of the three systems were 98.1%, 98%, and 98.3% respectively. Conclusion The sensitivity and specificity of PSCS were superior to MODS and SOFA in predicting death risk after CABG.
ABSTRACT
Objective The aim of this study was to evaluate of adilty of two acute renal failure-specific scoring systenms (the classification by Bellome et al and the AKIN criteria) for predicting hospital mortality after cardiac surgery in adult patients. Methods Between October 1 st 2006 to Decemjber 31 st 2006, 509 adult patients who ungerwent coronary artery bypass grafting (CABG) and/ or valve operation were enrolled in this study. The medical data collection included gender, age, types of operation, perioperative he- modynamic parameters, urine output, biochemical parameters and outcome. Renal function was assessed daily according to the classi- ficatinn by Bellomo and the AKIN criteria, respectively. As references, Acure Physiology and Chronic Health Evaluation(APACHE) Ⅱ and Sepsis-related Organ Failure Assessment (SOFA) score were also calculated. Resuits Three hundred and forty-one patients were male (67.0%), and 168 were female (33.0%), mean age was (56.2±12.0) years old. Tnree hundred and nine patieats un- derwent CABG, 182 underwent valve operation and 18 underwent CABG plus valve operation, Mean duration of ventilation support was (20.4±17.7) houra, and the ICU stay was (1.4±1.0) days. Postoperative hospital stay was (13.8±9.1) days. According to the classification by Bellomo., the highest in-hospital mortality was 52.9% in ARFS group. Mahiplicatinn of in-hospital morality rate was abserved (X2 for trend, P<0.01) in 0.4% (non-ARF), 1.2% (stage 1), 12.0% (stal～ 2) and 32.4% (stage 3) of pa- tients based on the AKIN criteria. By applying the area under the receiver operating characteristic ourve, the classification by Bellomo and the AKIN criteria had good discriminative power. Furthering, multivariate logistic regression analysis verified that the Odds Ratio of the AKIN criteria was 5.478 (P =0.028, 95% Confidence Interval 1.027- 24.856), after adjusting for gender and age. Con- clusion Analytical data confinned good discriminative power of both the AKIN criteria and the classification by Bellomo for predicting hospital mortality of adult postoperative patient with ARF.
ABSTRACT
Objective Extracorporeal membrane oxygenation (ECMO) provides a treatment for patients with acute heart-lung failure. However, as an invasive procedure, it associated with high incidence of complications. It is important to a-vert and reduce the complications for improving the success rate in critically ill patients. We investigate the complications associated with ECMO after cardiac surgery and their management. Methods Clinical data from 117 postoperative patients[32 male, mean age (48.7 ± 16.5) years]supported with ECMO in the cardiovascular intensive care unit( ICU) from March 2005 to June 2008 were analyzed retrospectively. The cardiac operations they had undergone included coronary artery bypass grafting (n = 20), coronary artery bypass grafting and remodeling of left ventricle(n =9), coronary artery bypass grafting and valvular operation(n =5), repair of ventricular septal perforation following acute myocardial infarction(n =2), valvular operation( n = 46), heart/lung transplantation (n = 20/1), correction of congenital heart defects ( n = 10), and aortic operations ( n = 4). Venoarterial bypass was established in 110 patients by cannulation of the right atrium and femoral artery, and that of the right atrium and ascending aorta in 5 cases. Left atrial drainage to ECMO was added in 2 cases. Venovenous bypass was established in 2 patients with hypoxemia following cardiac surgery. Heparin was infused for maintaining the activated coagulation time (ACT) at 160 to 200 seconds for centrifugal pump(114 cases),and 200 to 250 seconds for roller pump(3 cases) to avoid thrombotic events until decannulation was achieved. Results The mean ECMO duration was 61 hours (range 3 to 225 hours). 48(41.0% ) patients died, 18 of them died of complications after weaning from circulatory assistant successfully. Complications occurred in 74 (63.2% ) patients included reoperation for hemostasis (n = 24), renal failure requiring renal replacement therapy (n =29), nosocomial infections ( n = 32) , ischemia in the extremities(n = 5), plasma leakage of oxygenators ( n = 29), gastroenteral hemorrhage ( n = 14), hemolysis ( n = 7 ), neurological complications ( n = 4) and centrifugal pump failure (n =1). Conclusion Bleeding is an early complication associated with ECMO support. The risk of nosocomial infection, renal failure and plasma leakage of oxygenators increases with the duration of ECMO support.
