1.Energy metabolism and related mechanism in patients with malignant tumors
Journal of Shanghai Jiaotong University(medical Science) 2010;30(1):42-45
Energy metabolism refers to the metabolism of three major nutrients associated with the process of energy production and usage.The metabolism in patients with tumors manifests specifically, as a result of tumor-bearing state, host's response to tumor and anti-neoplastic therapy.It is believed that resting energy expenditure increases in patients with newly diagnosed tumors, which is related to C-reactive protein and release of inflammatory cytokines. After eflfectjve therapy,resting energy expenditure decreases in some degree.In addition,the stage and differentiation of tumors also affect metabolism.However,there are some conflicts among research findings.The characteristics of energy metabolism and influential factors in patients with tumors are reviewed in this paper.

Objective To evaluate the possible factors that may influence the resting energy expenditure (REE) in patients with newly diagnosed esophageal cancer. Methods Totally, 40 patients with newly diagnosed esophageal cancer were prospectively collected from November 2008 to June 2009 in Xinhua Hospital. Nutritional risk screening 2002 (NRS 2002) was performed. REE and body composition were measured using indirect calorimetry and bioeletrical impedence method, respectively. Results Twenty-seven (67.5%) patients were found with nutrition risk, and NRS score was negatively correlated with prealbumin ( r = - 0.444, P = 0.004) and albumin levels (r = - 0.386, P = 0.014). Measured REE and predicted REE values were ( 6770 ± 1360) and (6021 ± 841 ) kJ/d, respectively (P < 0.001 ). Among all 40 patients, 57.5% of them were hypermetabolic,30.0% were normal, and 12.5% were hypometabolic. Stepwise linear regression analysis showed that fat free mass was the only significant determinant variable for REE (P < 0.001 ). Conclusion Fat free mass is a factor than can influence the energy metabolism in patients with newly diagnosed esophageal cancer.

Objective: To investigate echocardiography characteristics and clinical significance in patients with diastolic mitral regurgitation. Methods: A total of 15 patients with diastolic mitral regurgitation were studied including 1 patient with large volume of aortic regurgitation, 6 with atrial ifbrillation (AF), 2 with atrial lfutter, 1 with II° type I atrio-ventricular block (A-V block), 1 with II° type II A-V block and 4 with III° A-V block. The characteristics of mitral regurgitation were observed, the heart rates, left ventricular size were measured and left ventricular function was detected in all patients. Results: There was 1 large volume aortic regurgitation patient with diastolic mitral regurgitation occurred in slow iflling phase with less volume, it was less than positive velocity; 1 AF patient occurred in mid and late diastolic phase with less volume, it was obviously less than positive velocity; the rest 8 patients all occurred in mid and late diastolic phase, the velocity reached or surpassed to positive velocity. All 15 patients had slow heart rate, increased left heart, decreased left ventricular ejection fraction, tissue Doppler imaging showed that the early diastolic peak slowed down in mitral ring. There were 93% (14/15) patients having obvious systolic regurgitation. Conclusion: The time phase, quantity and velocity of diastolic mitral regurgitation have various characteristics, most of them associated with systolic regurgitation combining abnormal cardiac structure and function. Echocardiography provides important information for clinical treatment.

Objective To investigate the clinical value of the gated blood pool imaging phase analysis method in the evaluation of left ventricular mechanical synchronization in patients with chronic heart failure. Methods A total of 169 patients with chronic heart failure were enrolled in our study , using gated blood pool imaging phase analysis method to obtain left ventricular phase angle width ( PHB) and left ventricular phase angle standard deviation ( PSD) as evaluating left ventricular mechanical synchrony index; using tissue Doppler imaging (TDI) measurement of the standard deviation of systolic peak time(Ts-SD) of each segment by using the current prevailing 12 non-apical segments analysis method as evaluating left ventricular mechanical synchrony index, and parameters derived from both methods were compared. Results LVPHB was highly correlated with Ts-SD (r = 0. 83 ,P = 0. 000 ) . LVPSD was modestly correlated with Ts-SD ( r - 0. 69, P = 0. 000) . The ejection fraction measured by echocardiography was (42.93 ± 14. 89) % ,which was significantly higher than that measured by ERNA (39. 76 ± 17. 89)% (P <0. 01). Conclusions The evaluation of left ventricular mechanical synchrony in patients with chronic heart failure by the gated blood pool imaging can provide similar information with TDI, which can simultaneously measure two ventricular functions and get more accurate measurement of ejection fraction. Cardiac resynchronization therapy patients can be identified by combining two kinds of approaches, and cardiac resynchronization therapy responders could be improved as well. More patients with heart failure can benefit from cardiac resynchronization therapy therapy.

Diabetic cardiomyopathy is a myocardial complication associated with abnormal glucose metabolism and dyslipidiaemia, which increases the risk of death and heart failure in diabetic patients. Mitochondrial dysfunction is involved in the occurrence and development of diabetic cardiomyopathy. Recent studies have confirmed that scavenging damaged mitochondria in cardiomyocytes through mitophagy can restore mitochondrial homeostasis, reduce oxidative stress and improve diabetic cardiomyopathy. Therefore, this article provides a comprehensive review of the mechanisms and characteristics of mitochondrial autophagy in diabetic cardiomyopathy. It aims to offer new insights and theoretical basis for the prevention and treatment of diabetic cardiomyopathy.

OBJECTIVETo investigate the implications of a prenatal diagnosis of single umbilical artery (SUA) for chromosomal abnormalities and neonatal outcomes.
METHODSFrom January, 2008 to June, 2012, color Doppler ultrasound identified 44 fetuses with SUA. Prenatal diagnoses with amniocentesis or umbilical blood sampling were subsequently ordered for routine chromosome karyotyping and the newborns were followed up for assessing the neonatal outcomes.
RESULTSOf all the 44 fetuses, 24 had uncomplicated SUA, and 20 had other concurrent abnormalities (including 8 with abnormal ultrasound soft indexes and 12 with chromosomal abnormalities). The two groups of fetuses showed significant differences in gestational weeks at delivery and incidence of chromosomal abnormalities but not in neonatal weight, placenta weight or APGAR score.
CONCLUSIONSFetuses with a prenatal diagnosis of SUA and other development abnormities need to undergo prenatal chromosomal examination. For fetuses with uncomplicated SUA, careful ultrasound examination is necessary to avoid missed diagnosis of potential congenital abnormalities.

Objective To evaluate the clinical outcome of fetus diagnosed as mild and moderate isolated ventriculomegaly(IVM)and its correlation with imaging follow-up. Methods Totally,161 cases of single pregnancy whose fetus was diagnosed as mild or moderate IVM by ultrasound were administrated. Data of prenatal ultrasound examination, pregnancy outcomes, and the postnatal MRI results were collected. New borns' growth and development, language expression, movement coordination, auditory and visual function were followed up to evaluate the neurodevelopment. Results (1)Before birth:80.1%(129/161) of IVM disappeared before the delivery, 16.1%(26/161)remained stable, and 3.7%(6/161)continued to deteriorate.(2)Postnatal MRI: 8 cases(9.6%, 8/83)were diagnosed IVM, of which 3 cases were found additional abnormalities(1 case was the corpus callosum dysplasia and 2 cases were leukodystrophy). The additional abnormal detection rate was 3/8.(3)Postnatal assessments: There were 7 cases(8.9%, 7/79) neunatal behavioral neurological assessment (NBNA), 6 cases (7.6%, 6/79) Bayley scales of infant development (BSID)-psychomotor developmental index(PDI) and 3 cases (3.8%, 3/79) BSID-mental development index(MDI) whose scores were low. There was no significant difference of the NBNA and BSID scores between mild and moderate IVM (NBNA: x2=2.042,P=0.210; BSID-PDI: x2=-1.359,P=0.174; BSID-MDI: x2=-1.205,P=0.228). Follow-up of 9 cases(11.4%, 9/79)with low BSID score, 6 of them were found to be stable in the medial ventricle of the uterus, and the size of the lateral ventricle was normal after birth by ultrasound and MRI. Conclusions The majority of IVM fetuses have good prognosis, but there is also a risk of neurodevelopmental dysplasia. The postnatal follow-up should be paid attention to, and MRI should be performed as the postnatal imaging evaluation.
