Abstract?AIM:To study the Influence and outcomes of eye healthcare information teaching for the visual development of children under“combination of medicine and education” in kindergartens.?METHODS:The children(5-6 years old) were randomly selected from 6 kindergartens in Nanjing, 3 in Yuhua District as the experimental group, and the other 3 in Jianye District as the control group.A one-year follow-up was conducted to evaluate the difference of visual development, including the rate of low vision, rate of referral caused by refractive abnormality, rate of astigmatism, the average of the equivalent spherical lens and the rate of lacking physiological hypermetropia, between the experimental group and the control group children.?RESULTS:One school year later,the rate of low vision, rate of referral caused by refractive abnormality and the rate of astigmatism, were significantly lower (P<0.05)in the experimental group under the mode of“combination of medicine and education”, which were also lower than those before experiment(P<0.05).The average of the equivalent spherical lens of experimental group increased and the rate of lacking physiological hypermetropia decreased significantly, compared with the control group ( P <0.05 ) and with those before experiment(P<0.05).?CONCLUSION:Using “combination of medicine and education” eye health care model,is good for children's visual development,so as to reduce the rate of low vision and delay the occurrence of myopia.

AIMTo investigate the relations between left ventricular hypertrophy and systolic blood pressure (SBP), diastolic blood pressure (DBP), mean arterial pressure (MAP), neuropeptide Y (NPY) during cardiac hypertrophy and regression.

METHODSBlood pressure and heart rate were recorded with polygraph channel biologic message system. NPY in plasma and myocardium were measured with Radioimmunoassay. Correlation coefficient were calculated with SPSS software.

RESULTSThere were positive correlations between SBP, DBP, MAP, NPY in the cardiac tissue and cardiac coefficient (LVW/BW). There was no correlations between cardiac coefficient and heart rate (HR), NPY in plasma.

CONCLUSIONHypertension is one of cardiac hypertrophy factors, SBP correlate better with LVW/ BW than DBP. SBP, DBP, MAP, NPY in cardiac tissue has correlative tendency with LVW/BW.

AIM To study the effects of Zishen Yutai Pills (Codonopsis Radix,Dipsaci Radix,Morindae officinalis Radix,etc.) on endocrine in diminished ovarian reserve (DOR) rats.METHODS Female SD rats with normal oestrous cycle were induced by intragastric administration of 55 mg/(kg · d) tripterygium glycosides for fourteen days to establish DOR model,and then divided into Zishen Yutai Pills high-,low-dose groups,Bujiale group,model control group and negative control group.After 35 days' administration,serum estradiol (E2),follicle-stimulating hormone (FSH),luteinizing hormone (LH) and progesterone (P) levels were detected by ELISA.And ovarian tissue estrogen receptor (ER),follicle-stimulating hormone receptor (FSHR) and luteinizing hormone receptor (LHR) expressions were detected by immunohistochemical method.RESULTS Compared with the negative control group,there were significant changes in levels of E2,FSH,LH,P,and expressions of ER,FSHR,LHR in the model control group (P ＜ 0.05),but there were no statistical significances in body weight,ovary index,uterus index and serum FSH/LH level between the two groups (P ＞ 0.05).Compared with the model control group,E2 level was increased in the Zishen Yutai Pills high-,low-dose groups and Bujiale group,FSH,LH levels were decreased,and they also promoted ER expression and restrained FSHR,LHR excessive expressions,which were statistically significant (P ＜ 0.05).P level was significangly increased in different dose groups (P ＜ 0.05),FSH/LH in the high-dose group was obviously decreased (P ＜ 0.05),and body weight,ovary index,uterus index in various intervening groups showed no statistical significances (P ＞ 0.05).CONCLUSION Zishen Yutai Pills can improve ovarian reserve function in DOR rats by affecting the expression of ovarian tissue hormone receptor and regulating endocrine function.

Amniotic fluid embolism is a rare but extremely dangerous complication in pregnant women.Its pathogenic pathophysiological nature is an immune process of the mother.This cascade endogenous immune response can quickly cause multiple organ dysfunction of the mother.Therefore,the treatment for this disease requires a multi-disciplinary and close collaborative medical rescue team in order to ensure the maternal and fetal safety in China.

OBJECTIVE: To assess the performance of a high-definition CT (HDCT) for imaging small caliber coronary stents (< or = 3 mm) by comparing different scan modes of a conventional 64-row standard-definition CT (SDCT). MATERIALS AND METHODS: A cardiac phantom with twelve stents (2.5 mm and 3.0 mm in diameter) was scanned by HDCT and SDCT. The scan modes were retrospective electrocardiography (ECG)-gated helical and prospective ECG-triggered axial with tube voltages of 120 kVp and 100 kVp, respectively. The inner stent diameters (ISD) and the in-stent attenuation value (AVin-stent) and the in-vessel extra-stent attenuation value (AVin-vessel) were measured by two observers. The artificial lumen narrowing (ALN = [ISD - ISDmeasured]/ISD) and artificial attenuation increase between in-stent and in-vessel (AAI = AVin-stent - AVin-vessel) were calculated. All data was analyzed by intraclass correlation and ANOVA-test. RESULTS: The correlation coefficient of ISD, AVin-vessel and AVin-stent between the two observers was good. The ALNs of HDCT were statistically lower than that of SDCT (30 +/- 5.7% versus 35 +/- 5.4%, p < 0.05). HDCT had statistically lower AAI values than SDCT (15.7 +/- 81.4 HU versus 71.4 +/- 90.5 HU, p < 0.05). The prospective axial dataset demonstrated smaller ALN than the retrospective helical dataset on both HDCT and SDCT (p < 0.05). Additionally, there were no differences in ALN between the 120 kVp and 100 kVp tube voltages on HDCT (p = 0.05). CONCLUSION: High-definition CT helps improve measurement accuracy for imaging coronary stents compared to SDCT. HDCT with 100 kVp and the prospective ECG-triggered axial technique, with a lower radiation dose than 120 kVp application, may be advantageous in evaluating coronary stents with smaller calibers (< or = 3 mm).

OBJECTIVETo apply echocardiography in diagnosis of isolated noncompaction of ventricular myocardium (INVM) in adults.

METHODSSix patients with INVM underwent echocardiographic examination using HP5500 ultrasound system with the frequency of 2 approximately equals 4 MHz, and the observation was focused on ventricularmyocardium and endocardium at one-third of the apex.

RESULTSAll 6 patients showed typical echocardiographic images characterized by an altered structure of the ventricular myocardium with extremely thickened, hypokinetic segments consisting of two layers: a thin, compacted epicardium and an extremely thickened endocardium, resulting in an extremely thickened ventricular wall.

CONCLUSIONEchocardiography should be the first choice to be applied in diagnosis of INVM, which is a distinct entity of specific cardiomyopathy in adults.

OBJECTIVETo research the maturation regulation of dendritic cells (DCs) pulsed with hepatocellular carcinoma (HCC) cell soluble antigens.

METHODSBCG HSP 70 was purified by SDS-PAGE electrophoresis and its biological activity was determined with ELISA. Phenotypes of DCs pulsed with antigens or with both antigens and BCG HSP 70 were analysed with flow cytometry. MTT assay was used to estimate the proliferation of self lymphocytes and the mixed lymphocyte reaction (MLR) of BCG HSP 70 primed DCs.

RESULTSThe characteristics of DCs had changed after loaded with soluble antigens of HCC. There were about 10% DCs which had lost their specific markers. The expression levels of CD54, CD83, CD86 molecules and the stimulatory ability in allogeneic MLR decreased. However, after being activated by BCG HSP 70, the DCs pulsed with antigens could keep their special markers and the expression levels of CD54, CD83, CD86 molecules increased too. The stimulatory abilities in allogeneic MLR and proliferation of self lymphocytes also improved.

CONCLUSIONThis study shows that BCG HSP 70 can induce DCs pulsed with antigens maturation and improve their antigen-presenting ability, which may be a useful maturation inducer for dendritic cells.
