1.EFFECTS OF STATIC EXERCISE AND DYNAMIC EXERCISE ON SYSTOLIC TIME INTERVALS (STI) IN CHILDREN
Chinese Journal of Sports Medicine 1982;0(02):-
The purpose of this study was to investigate STI changes resulting from static and dynamic exercises in boys, 9-10 years old, so as to reveal the effects of physical work of different types and loads on the heart function.Our research showed that the effects of static load and dynamic load on STI in children were different. After dynamic exercise all items of STI changed significantly and PEP/LVET decreased significantly. No PEP change was found after static exercises (50% and 80% max load). Static exercise of 50% max load resulted in no IVCT change, but static exercise of 80% max load resulted in very significant change of IVCT, and the longest recovery period was found afterwards. Thus, 80% static exercise would result in a heavy, transient heart load in children.Our research also showed that the changes of HR?systolic blood pressure?LVET after dynamic load and static load were significantly different indicating that oxygen consumption in heart muscles was higher during dynamic exercise and the effect of dynamic exercise on heart was stronger.

Objective To observe the clinical efficacy of bipolar hemi arthroplasty and PFNA internal fixation for elderly patients with unstable intertrochanteric fracture.Methods The data of 79 elderly patients with unstable intertrochanteric fracture in our hospital from Au-gust 2013 to August 2014 were analyzed retrospectively.According to different surgical methods,79 cases were divided into observation group (n =40)and control group(n =39).The observation group were treated by artificially double-acting avascular replacement,and the control group received PFNA internal fixation.The operation time,intraoperatve blood soss,bedridden time,clinical effecacy and complications were recorded and observed.Results The operative time and bed time of observation group were significantly shorter than those of control group, the difference was statistically significant(P <0.05).The total postoperative complication rate of observation group was 20.00%,which was higher than 20.51% of control group,the difference was statistically significant (P <0.05).The Harris scores in observation group 3 months and 6 months after surgery were significantly higher than those in control group,the differences were statistically significant(P <0.05).Con-clusion Both artificially double-acting avascular replacement and PFNA internal fixation have a good effect on elderly patients with unstable intertrochanteric fracture.The artificially double-acting avascular replacement has the advantages of less blood loss,faster recovery and less postoperative complications,which is conducive to improving the quality of life of patients.

Objective To summarize the effect of supra-arch branches bypass combined with endovascular aortic repair for aortic diseases.Methods From January 2012 to August 2015,120 cases of thoracic aortic diseases (aortic dissection 103,aortic aneurysm 16,penetrating aortic ulcer 1) received hybrid operation in Guangdong Cardiovascular Institute.Vascular bypass was established among the brachiocephalic arteries,followed by endovascular repair through femoral artery either one-stage or two-stage.Patients were followed up for 3-24 months.Results Technical success was achieved among all the patients.Five patients died after the operation(one patient had retrograde aortic dissection,2 patients had pericardial tamponade,one patient had apnea,and one patient had respiratory and cardiac arrest.The death rate is 4.1%),4 patients had stroke,among them,symptoms were relieved in three patients,one patient was not cured.Total 92 patients were followed-up and had no symptoms of up-limb ischemia or dizziness.CT scan showed bypass graft and endovascular stent patency.6 patients had endoleak (type Ⅰ b 2 cases,type Ⅱ 3 cases,and type Ⅲ 1 case),distal aortic dissection occurred in one patient,three patients had mild contrast agent leakage around the distal endovascular stent,type A aortic dissection occurred in one patient,there were no late stage death.Conclusion Supraarch branches bypass combined with endovascular aortic repair for treating aortic disease is minimally invasive,safe,and can reduce the incidence of postoperative complications.

Objective To explore the MRI features of pelvic endometriosis outside the ovary.Methods 13 patients with pelvic endometriosis outside the ovary were imaged.Their clinical and imaging data were reviewed retrospectively.All cases were con-firmed by pathology.An enhanced MR using T1 WI sequence both in sagittal and transverse position was performed after T2 WI fat-suppression sequence and T1 WI sequence.Our MRI study was focused on the distribution of lesions locating in the deep pelvic cavity and abdominal wall,and the features of MRI signals .Results 13 lesions were found,in which 4 lesions located in the rectouterine pouch of Douglas,2 cases the bladder wall,2 cases the unilateral cystic inlet of ureter,1 case the anal canal wall,and 4 cases the ab-dominal wall.10(10/13)lesions were shown as solid nodules while 3(3/13)lesions as cyst-solid ones.All lesions showed moderate-ly heterogeneous enhancement.Conclusion Pelvic endometriosis outside the ovary mainly shows solid or cyst-solid lesions that lo-cates in the urinary,uterus,rectal wall and spaces around them.MR images show a higher value for the detection of the lesions out-side the ovary.

Objective To evaluate the prevalence and impact of coronary artery disease (CAD) in aged patients with Stanford type B aortic dissection(AD).Methods From January 2008 to December 2011,CAG was routinely performed before aortography and thoracic aortic repair(TEVAR) to determine the prevalence of concomitant CAD in 200 consecutive Stanford type B AD patients who were older than 50 years.All patients received 1 year follow-up.Adverse events were compared between patients with and without concomitant CAD.Data analysis by SPSS 17.0 statistical software,using Student t test,Chi-square test and Fisher exact test.Results CAG showed 53 patients (26.5%) had CAD.Multivariate logistic regression analysis showed that male gender(OR =4.415,95% CI:1.131-17.237,P =0.033) and age (OR =1.061,95% CI:1.017-1.108,P =0.006) were independent predictors of Stanford type BAD coexisted with CAD.Age was also independent predictor of multi-vessel disease(MVD) and/or left main disease(LMD) (OR =1.096,95% CI:1.009-1.191,P =0.023).At 30-day follow-up,there was no difference in the incidence of adverse events between patients with and without concomitant CAD.Patients with concomitant CAD showed higher incidence of myocardial infarction[3 (5.66%) vs.0(0),P =0.018] and stroke [4 (7.55 %) vs.1 (0.68 %),P =0.018].Conclusion The prevalence of CAD in aged patients with Stanford type BAD is relatively high.Concomitant CAD is associated with higher risk of cardio-cerebrovascular ischemic events while dose not increase the risk of adverse aorta related events.

To compare the effects on hemodynamics of univentricular support with that of biventricular support on experimental ischemic biventricular dysfunction so as to provide experimental basis for clinical usage of the Luo-Ye pump. Eight canines were placed with a left ventricular assist device (LVAD; left atrial-aorta bypass) and a right ventricular assist device (RVAD; right atrial-pulmonary artery bypass). Left anterior descending coronary artery(LAD) was ligated, three minutes later, the proximal of right coronary artery (RCA) was ligated to establish animal madel of acute ischemic biventricular dysfunction. First start the LVAD, and then RVAD was started five minutes later. The hemodynamic data were recorded including central venous pressure(CVP), cardiac output (CO), mean artery pressure(MAP), and pulmonary artery pressure(PAP) and pulmonary capillary wedge pressure (PCWP). During biventricular assist devices (BVAD) the hemodynamics were improved remarkably, MAP increased from 37.4 +/- 8.8 mmHg to 84.2 +/- 9.7 mmHg (P < 0.01) (the normal level), CO increased from 0.82 +/- 0.1 L/min to 1.33 +/- 0.12 L/min (P < 0.01), CVP decreased from 14.6 +/- 2.3 cmH2O to 4.2 +/- 1.5 cmH2O (P < 0.01), PCWP decreased significantly from 14 +/- 3.9 mmHg to 1.6 +/- 0.9 mmHg. These data suggest that LVAD during biventricular dysfunction could not improve the hemodynamics to normal level. Howere BVAD could increase CO and MAP to normal level and decrease heart work and myocardial oxygen consumption, which could help to improve myocardial metabolism and myocardial function. Therefore, BVAD is the first choice in treating severe biventricular dysfunction which was not respond to drug therapy and intra-aortic balloon pump (IABP).
