Fifty-four children, aged 1.5-3.5 years, were selected from a nursery and divided into three groups. To the children in group 1 multivitamin fortified formular milk powder of Hai-He brand (70g daily) was given as a supplementary food in addition to the normal diet and whole milk powder of Hai-He brand was given to group 2 as another supplementary food. The third group served as control. This observation was lasted for three months. At the end of the third month, the increments of body weight of the children, tricep skinfold and circumference of upper arm of group 1 were higher than those of group 3 significantly, but there were no significant differences between group 1 and group 2. The hemoglobin content of group 1 increased by 0.8g/dl but group 2 and 3 decreased by 0.53g/dl and 0.72g/dl respectively. At the end of our observation, the concentrations of vitamin B1, C and PP in urine of group 1 were higher than those of other two groups by vitamin load test.Thus, we may consider that the multivitamin fortified milk powder is better than the whole milk powder in improving the vitamin and iron nutritional status of young children.

Objective To compare the accuracy of real-time myocardial contrast echocardiography (RT-MCE) with DISA-SPECT in detecting hibernating myocardium. Methods Fourteen hospitalized patients with regional wall motion abnormalities (RWMA) underwent RT-MCE, DISA-SPECT, coronary angiography and percutaneous coronary intervention(PCI). Every left ventricular myocardial segment image was acquired and evaluated according 16-segment model of American Society of Echocardiography. The Motion of every segment was observed by echocardiography after 1,3,6 months. The gold standard is that the motion of ventricular segment get better after PCI. The images of RT-MCE and DISA-SPECT were analyzed semi-quantitatively. Results The sensitivity,specificity,accuracy of RT-MCE and DISA-SPECT in detecting hibernating myocardium were 74.60%, 91.7%, 81.3% and 93.3%, 75.0%, 86.2%, respectively. RT-MCE had more value in specificity while DISA-SPECT had more value in sensitivity. The correlation between two methods was good in detecting hibernating myocardium. Conclusions RT-MCE and DISA-SPECT can be used as valuable methods to detect hibernating myocardium, the correlation between two methods is good and they have more value in specificity and sensitivity respectively.

Recently, the D'Amico classification system is widely used for the risk stratification of prostate cancer (PCa) , although no consensus has been reached for the definition of high-risk PCa. This system defines high-risk PCa as a prostate-specific antigen (PSA) level > 20 ng/ml, a Gleason score of 8-10, or a clinical stage ≥ T2c. Because high-risk PCa is prone to recurrence and metastasis after treatment, a proper initial therapy plays a crucial role. Currently, radical prostatectomy and radiation therapy are considered to be two most important options for the initial treatment of high-risk PCa although it remains controversial which is better.

OBJECTIVETo evaluate the fetal cardiac function in gestational diabetes mellitus (GDM) pregnancies under different maternal glycemic controls.
METHODSForty four GDM mothers received 78 fetal echocardiographic evaluations at three gestational periods (<28, 28-34 and >34 weeks) and were divided into poorly-(DM1) and well-(DM2) controlled groups according to their glycemic control at examination. Seventy uncomplicated mothers were selected as controls. Parameters of fetal cardiac anatomy and function were measured and analyzed.
RESULTSGDM fetuses' cardiac ventricular walls were thicker than controls', and the differences between DM1 and DM2 were not significant except for end-diastolic left ventricular walls. In both GDM groups, the aortic flow velocities increased earlier than pulmonary artery and DM1 fetuses changed earlier than DM2 ones. GDM fetuses' left atrial shortening fraction was smaller than the controls' in the period of ⩾34 weeks and negatively correlated with thicknesses of left ventricular walls and interventricular septum in DM1 fetuses (r=-0.438 and -0.506). The right ventricular diastolic function in DM1 and DM2 fetuses decreased after the period of 28-34 weeks and in the period of >34 weeks respectively. Tei index of both left and right ventricles increased in DM1 group after the period of <28 weeks and in DM2 group only in the period of ⩾34 weeks, with no significant differences between DM1 and DM2 groups in this period.
CONCLUSIONFetuses of GDM mothers showed cardiac function impairments. Good maternal glycemic control may delay the impairments, but cannot reduce the degree. Some cardiac changes in GDM fetuses were similar to those in pregestational diabetic pregnancies except for several parameters and their changing time.

OBJECTIVETo study the feasibility of umbilical cord brain natriuretic peptide (BNP) level measurement for the evaluation of perinatal cardiac function in fetuses from pregnant women with abnormal blood glucose levels and the influence of abnormal blood glucose on fetal cardiac function.
METHODSTwenty-four mothers with gestational diabetes mellitus (n=18) or gestational impaired glucose tolerance (n=6) (diabetic group) were classified into two subgroups according to blood glucose level before delivery: good (n=17) and poor (n=7) glucose control. They underwent fetal echocardiography in their late pregnant periods and fetal cardiac sizes and function were measured. Twenty-five normal pregnant mothers served as the control group. Umbilical cord blood BNP concentrations were measured at delivery.
RESULTSThe umbilical cord blood BNP concentrations in the diabetic group were significantly higher than in the control group(114.0+/-39.0 pg/mL vs 80.6+/-13.7 pg/mL; p<0.01). The poor glucose control subgroup demonstrated higher umbilical cord blood BNP concentrations than the good glucose control subgroup (142.1+/-44.1 pg/mL vs 102.4+/-31.2 pg/mL; p<0.01). No difference was found between the gestational diabetes mellitus and the impaired glucose tolerance groups. The BNP concentration was positively correlated to the thicknesses of fetal left ventricular walls and the peak velocities of mitral A wave (r=0.715, 0.491 respectively, p<0.05), and negatively correlated to the mitral E/A ratio (r=-0.507, p<0.05).
CONCLUSIONSThe fetuses of pregnant women with abnormal blood glucose levels have an increased BNP level in umbilical cord blood. Umbilical cord BNP level is related to maternal blood glucose control and the changes in fetal cardiac function. It may reflex the latent impairments of fetal cardiac function. A good glucose control may decrease the impact of abnormal maternal blood glucose on fetal hearts.

OBJECTIVETo investigate the effects of cyclosporine A (CsA), a powerful inhibitor of mitochondrial permeability transition pore (MPTP), on pneumocyte apoptosis, the release of cytochrome C and the activity of caspase-3 after lung ischemia/reperfusion, and explore the mechanisms.
METHODSSingle lung in situ ischemia/reperfusion animal model was used. 30 SD rats were randomly divided into three groups (n = 10): sham (S) group, ischemia/reperfusion (I/R) group and cyclosporine A (CsA) group. Apoptosis of pneumocyte was assessed by TUNEL method, cytochrome C (CytC) in cytoplasm was detected by immunohistochemistry techniques, and the activity of caspase-3 was measured with spectrophotometer.
RESULTSThe content of CytC in cytoplasm, the activity of caspase-3, and the value of apoptosis index (AI) in ischemia/reperfusion group were evidently higher than that in S group (P < 0.01). CsA suppressed apoptosis as well as CytC release and caspase-3 activity (P < 0.01).
CONCLUSIONCsA can prevent the release of cytochrome C, block the apoptosis of pneumocyte accordingly maybe by closing the MPTP.
