Objective To study effects of mitral valve replacement(MVR) on the old with mitral valve diseases(MVD). Methods The documents of 265 cases undergoing MVR were reviewed, who aged 60 years old or over between June 1991 and June 2003. Demographices, clinical preoperative conditions, indications to surgery, early postoperative course and long-term outcome were collected via hospital documents and outpatient follow-up. Many risk factors were analysed. Results Follow-up rate amounted to 93.7%(236/252). The mortality was 4.9% (13/265) within 30 days. Heart failure and renal failure were the main cause of death. Compared with younger patients(lt;60 years old), long-term survival rate was lower in the old, 5-year 87.52% vs 96.84%, 10-year 81.23% vs 94.87%. There were 15 late deaths(0.17% case/M), most of whom died of heart failure, cancers and lung infections. Risk factors for MVR in the old included New York Heart Association class Ⅳ, diabetes, and lung incompetence. Conclusions The patients with MVD over 60 years old tended to present high postoperatively mortality and morbidity.
ObjectiveTo investigate the specific CT findings of high-risk gastrointestinal stromal tumors (GISTs). MethodsCT findings of 24 patients with high-risk GISTs from August 2009 to March 2014 proved by surgery and pathology were retrospectively reviewed. ResultsTwelve of the high-risk GISTs were from the stomach, 11 from the small intestine (5 from duodenum, 4 from jejunum, and 2 from ileum), and 1 from the rectum. The biggest transverse diameter of the tumor was between 2.5 and 15.0 cm, and 2 were less than 5 cm and 22 of them were over 5 cm. The tumors appeared as irregular in 20 cases, and with indefinite boundary in 21 cases. Twenty-four tumors showed different levels of necrosis and cystic change, 15 showed ulcer, 2 showed perforation with effusion and pneumatosis, and 3 showed calcification. The enhancement of lesion was mostly moderately to markedly inhomogeneous. High-risk small intestinal stromal tumors had more significant enhancement and vessels. Hepatic metastasis in 3 cases was detected. ConclusionCT features of HRGISTs can be found with certain characteristics, which may contribute to the diagnosis.
ObjectiveTo compare clinical outcomes between coronary artery bypass grafting (CABG)and off-pump coronary artery bypass grafting (OPCAB)for high-risk coronary artery disease (CAD)patients with high European System for Cardiac Operative Risk Evaluation (EuroSCORE). MethodsA total of 211 CAD patients undergoing surgical treatment in the Department of Cardiovascular Surgery, Anhui Provincial Hospital Affiliated to Anhui Medical University from June 2007 to July 2013 were enrolled into this study, including 52 patients receiving CABG and 159 patients receiving OPCAB. Predicted risk of operative mortality (PROM)of each patient was calculated by EuroSCORE. Patients with PROM≥6 were stratified into high-risk subgroups. Clinical outcomes were compared between CABG and OPCAB patients, as well as incidence of cardiovascular events, angina and stroke within 30 postoperative days in high-risk subgroup patients. ResultsOPCAB and CABG group patients had similar left main disease. There was no statistical difference in the number of distal anastomosis between OPCAB (2.75±0.82)and CABG group patients (2.83±0.58) (P > 0.05). Operation time[ (3.92±0.79)hour vs. (6.83±1.53)hour], thoracic drainage[ (983.14±802.39)ml vs. (1 620.40±879.32)ml], blood transfusion[ (1 289.30±668.08)ml vs. (2 325.30±491.98)ml], length of ICU stay[ (3.90±1.33)days vs. (5.08±1.78)days], and mechanical ventilation time[ (9.63±3.32)h vs. (13.76±3.79)h] of OPCAB group patients were significantly shorter or lower than those of CABG group patients (P < 0.05). There was no statistical difference in 30-day mortality between OPCAB and CABG group patients (1.26% vs. 3.85%, P > 0.05). Among high-risk subgroup patients, the odds ratio of stroke within 30 postoperative days in CABG was 5.7 (95%CI 1.28-25.09, P < 0.05)compared with OPCAB group patients, and the incidence of cardiovascular events and angina within 30 postoperative days were similar between the 2 subgroups. ConclusionsPostoperative mortality and number of distal anastomosis are not significantly different between CABG and OPCAB patients, but OPCAB can significantly reduce operation time, thoracic drainage, blood transfusion, length of ICU stay and mechanical ventilation time compared with CABG. For high-risk patients with high EuroSCORE, OPCAB can better reduce the incidence of postoperative stroke compared with CABG.
Objective To identify the high risk factors related to postpartum suicide. Methods A total of 40 women with postpartum depression who had suicidal act or ideation were included in the study. They were evaluated by the Edinburgh Postpartum Depression Scale (EPDS), the Life Events Scale (LES) and the Social Support Rate Scale (SSRS), and compared with healthy postpartum women. The multi-element gradual regression analysis was performed to identify the high risk factors. Results Such factors as prior history of depression, negative life events within the previous half year, absence of social support, disease of mothers or infants, and conjugal relationship were significantly correlated with postpartum suicide. Conclusion It might be helpful to reduce the incidence of postpartum suicide by prenatal mental intervention and postpartum crisis intervention.

Abstract： Objective To analyze clinical outcomes of intra-aortic balloon pump （IABP） application for high-risk patients before undergoing off-pump coronary artery bypass grafting （OPCAB）， and summarize our experience and weaning indications of IABP. Methods We retrospectively analyzed clinical data of 102 high-risk patients with coronary artery disease who underwent IABP implantation before OPCAB from January 2008 to July 2011 in Zhongshan Hospital of Fudan University. There were 71 male patients and 31 female patients with their average age of 63.0±8.2 years in this IABP group. We also chose another 100 patients without IABP implantation before undergoing OPCAB as the control group， including 55 male patients and 45 female patients with their average age of 64.1±9.5 years. Postoperative systolic arterial blood pressure （SABP）， mean arterial blood pressure （MABP）， mechanical ventilation time， length of intensive care unit（ICU） stay， morbidity， duration of IABP treatment and in-hospital mortality of two groups were compared. Left ventricular ejection fraction （LVEF） was evaluated with echocardiography 3 months after surgery. Results Postoperative SABP （95.3±12.2 mm Hg vs. 80.1±11.7 mm Hg；t=8.440， P=0.000） and MABP （78.9±13.5 mm Hg vs. 52.3±15.1 mm Hg； t=12.410， P=0.000） of the IABP group were significantly higher than those of the control group. Mechanical ventilation time， length of ICU stay and duration of inotropic support of the IABP group were significantly shorter than those of the control group. The incidence of ventricular arrhythmia， low cardiac output syndrome， perioperative myocardial infarction and dialysis-requiring acute kidney failure of the IABP group were significantly lower than those of the control group. In-hospital mortality of the IABP group was significantly lower than that of the control group ［5.9% （6/102） vs. 17.0% （17/100）， χ 2 =6.180， P=0.020］. Ninety-six patients in the IABP group and 83 patients in the control group were followed up for 3 months. Three months after surgery， echocardiography showed that LVEF of the IABP group was significantly higher than that of the control group（45.3%±12.0% vs. 39.1%±8.2%， t=3.950， P=0.000）. Conclusion Preoperative prophylactic IABP implantation and optimal timing of weaning from IABP support can not only significantly reduce surgical risk and improve surgical outcomes and postoperative recovery of high-risk patients undergoing OPCAB， but also considerably ameliorate patient heart function and reduce perioperative morbidity and mortality.
With the development of transcatheter aortic valve replacement, it has become the first-line treatment for elderly patients with aortic valve stenosis. A case of transcatheter aortic valve replacement in a patient at high risk of coronary artery occlusion was reported. The use of intravascular ultrasound to observe the spatial relationship between the coronary ostia and the valve was the characteristic of this case. This patient was an elderly male who was assessed as a high risk of acute coronary artery occlusion before transcatheter aortic valve replacement. After fully evaluation of the patient’s surgical risks\benefits, the strategy was formulated. Percutaneous coronary intervention was the first step. At the same time, intravascular ultrasound was used to observe the spatial relationship between the coronary ostia and the valve, and balloon was embedded for coronary protection. The procedure went smoothly.
ObjectiveTo investigate the value of noninvasive positive pressure ventilation in patients with high risk of weaning induced pulmonary oedema.MethodsFrom June 2018 to June 2019, 63 patients with mechanical ventilation in the Department of Critical Care Medicine of the First Hospital of Lanzhou University were enrolled. Randomized digital table method was randomly divided into two groups and the resulting random number assignment was hidden in opaque envelopes, the experimental group received non-invasive positive pressure ventilation (n=32), and the control group received mask oxygen therapy ventilation (n=31). The heart rate, respiratory rate, means arterial pressure, hypoxemia, reintubation, blood gas analysis and other indicators were compared between the two groups after 2 hours of weaning. The length of hospital stay, mortality and complications were compared between the two groups.ResultsAfter 2 hours of weaning, the heart rate and respiratory rate were significantly lower in the non-invasive positive pressure ventilation group than in the mask group (P<0.05). There was no difference in mean arterial pressure between the two groups of patients, which was not statistically significant (P>0.05). The incidence of hypoxemia, laryngeal edema and reintubation in the noninvasive positive pressure ventilation group was significantly lower than that in the mask group, which was statistically significant (P<0.05), and the blood gas analysis index was better than the mask group (P<0.05). The non-invasive positive pressure ventilation group was significantly shorter than the mask group in the length of hospital stay and intensive care unit (P<0.05). The hospital mortality rate in 28 days was lower than that in the mask group (P<0.05), but there was no difference in tracheotomy, pneumothorax and subcutaneous emphysema between the two groups (P>0.05).ConclusionsNoninvasive positive pressure ventilation can effectively prevent hypoxemia, laryngeal edema, and re-intubation in patients at high risk of withdrawal related pulmonary edema. It can also shorten the length of hospital stay, which is worth clinical attention and promotion.
Objective To investigate the correlated risk factors of deep venous thrombosis (DVT) after the laparoscopic surgery. Methods Clinical records of 16 patients with DVT and 148 patients without DVT after laparoscopic surgery in Huashan hospital from Mar.2007 to Jan.2008 were analyzed retrospectively. Results There were several factors which could induce DVT after the laparoscopic surgery, including operation time ＞1 h 〔OR=4.15 （95% CI： 1.36-12.68）〕, operative site located in hypogastrium 〔OR=2.94 （95% CI： 1.07-8.08）〕 and the number of high risk factors ≥3 〔OR=3.94 （95% CI： 1.38-11.23）〕. Conclusions The long time of operation， hypogastric operation of laparoscopic surgery and high risk factors could induce DVT. Prevention measures should be made in preoperative period.
Objective To investigate the cognitive functions in people at high risk for schizophrenia.Methods Two hundred and twenty-two people at high risk for schizophrenia and 331 normal controls were assessed with 14 neuropsychological tests. Results The results of some neuropsychological tests in people at high risk for schizophrenia were worse than those in the normal controls. These tests included information, arithmetic, digital symbol, block design, logical memory, visual memory, Stroop test, verbal fluency, tower of Hanoi, WCST and CPT (Plt;0.01). The time for trail making test A in was longer in the group at high risk for schizophrenia than in the control group (Plt;0.05).Conclusion People at high risk for schizophrenia have general cognitive deficits. Attention and executive function may represent the genetic endophenotype for schizophrenia.
