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 diagnosis and classification of chronic obstructive pulmonary disease (COPD) in high risk populations living in metropolitan communities of Beijing. MethodsDuring January 2011 to December 2012,a cross-sectional survey including questionnaires and pulmonary function tests were performed in high risk populations of COPD (aged≥40 years with a history of smoking or chronic bronchitis) at 6 communities in Dongcheng District of Beijing. For those confirmed to have COPD,the dyspnea was rated by the modified Medical Research Council Dyspnea Scale (mMRC),and the frequency of acute exacerbations in the last year was recorded. The patients were classified by the Global Initiative for Chronic Obstructive Lung Disease (GOLD 2011) classification criteria. ResultsA total of 932 individuals,including 689 males (73.9%,aged 60.8±12.5 years) and 243 females(26.1%,aged 59.8±12.1 years),who had risk factors of COPD were included in the screening. COPD was confirmed in 203 patients,with the prevalence of 21.8%,and among whom only 31 cases (15.3%) had been diagnosed as COPD in the past. According to the revised GOLD classification in 2011,96(47.2%),38(18.7%),56(27.5%),and 13(6.4%) patients were classified into group A,B,C and D,respectively. The proportion of subgroup C1 (FEV1%pred <50% and the number of exacerbation in the last year <2) in group C was 71.4% (40/56). ConclusionIn the metropolitan communities of Beijing,screening the population with predisposing factors can increase the early diagnosis of COPD,which is often delayed by the lack of significant symptoms. The high proportion of patients in group C in this population implies that disease screening in high risk populations may be helpful for the prevention and treatment of COPD.
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.
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.

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.
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.
ObjectivesTo classify the high risk population for primary liver cancer (PLC) in rural China.MethodsBetween June 2011 and June 2013, hepatitis B surface antigen (HBsAg) carriers were identified in clinical laboratory of Qidong People’s Hospital and surveyed by questionnaires. Cox proportional hazard regression model was introduced to demonstrate independent risk factors associated with PLC occurrence. Moreover, receiver characteristic operating (ROC) curve was utilized to evaluate discrimination power of risk factor panel for PLC risk classification.ResultsA total of 1 296 HBsAg carriers were enrolled, among which 686 participants were male with an average age of 45.73±11.58 years, and 610 participants were female with an average age of 45.67±12.33 years. After a mean follow up period of 5.5 years, 43 incident PLC cases were confirmed, which generated a PLC incidence of 60.5 millions person years. Multi-univariate Cox model showed that increase of age (HR=1.055, 95%CI 1.029 to 1.083, P<0.000 1), male (HR=3.263, 95%CI 1.567 to 6.796,P=0.001 6), having family history of PLC (HR=2.315, 95%CI 1.260 to 4.252, P=0.006 8), HBeAg positivity (HR=2.367, 95%CI 1.267 to 4.419, P=0.006 9) and GGT abnormality (HR=2.721, 95%CI 1.457 to 5.083, P=0.001 7) were the independent risk factors of PLC.ConclusionRoutine host, viral and liver biochemical parameters which are readily accessible in daily clinical practice can be utilized in identification of the targeted population for prevention of PLC in rural China.
Objective To investigate the information of label use of high-alert drugs for children of high risk population, in the Military General Hospital of Beijing PLA. Methods We selected high-alert drugs used in this hospital as objectives. The package inserts of these drugs were investigated and medication parts for children were analyzed. Results 201 drugs regarded as high-alert drugs were included, of which only 78 drugs have accurate detailed description of medication for children, accounting for 38.8% of the total of investigated high-alert drugs. Conclusion Children, as high-risk population, needs more attention concerning the use of high-alert drugs. However, risks in the use of high-alert drugs increased due to the lack of the information of label use of high-alert drugs. To ensure the safety of drug use in children, the information of drug use for children in the package inserts should be urgently supplemented.
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.
