Objective To quantitatively analyze the fetal lung echo and right lung volume in the third trimester by real-time three-dimensional ultrasound (3-D US) and evaluate the feasibility of fetal lung maturity. Methods A total of 732 women with normal singleton pregnancies between 28 and 42 weeks of gestation underwent ultrasound examination. The 3-D US equipment with a 3.5-5MHz transabdominal transducer was used for the fetal biometric measurement. The echogenicity ratio between fetal lung and liver was compared. The fetal lung volume was calculated by the rotational multiplanar technique for volume measurement (VOCAL). Results The right fetal lung volume increased with the increase of gestational age with a linear positive correlation (r=0.884, P<0.01). After 34 weeks, the echogenicity ratio of fetal lung to liver was more than 1.1. Conclusion The echogenicity of lung/liver and fetal lung volume could be used as normal fetal predictable indicators for fetal lung maturity.

Objective To examine the possibility that a candidate causal species of the skin and lung tumor promotion induced by exposure to dimethylarsinic acid(DMAv)and dimethylarsinous acid(DMAⅢ),caused by the induction of oxidative stress in mice.Methods Two stages lung tumotigensis animal model induced by lung tumor initiator(4-nitroquinoline 1-oxide,4NQO)and promoter(DMAv)in ddY mice,was used to examine the effect of(-)epigallocatechin gallate(EGCG)on DMAv promoting lung tumorigenesis.Two stages skin tumorigenesis animal model induced by skin tumor initiator[dimethylbenz(α)anthracene,DMBA]and promoter(DMAⅢ)in hairless mice.was used to examine the effects of DMAⅢ in skin tumorigenesis and histopathology.The goxo-2'-deoxyguanosine (8-oxodG)in lung and epidermis were analyzed by HPLC.Results The incidence of lung tumors and 8-oxodG level of lung tissue decreased significantly in 4NQO+DMAv+EGCG group.compared with 4NQO+DMAv group (0.89±0.30 vs 4.00±0.82,1.21±0.09 vs 1.53±0.32,P＜0.01).The incidence of severe keratosis in DMBA+ DMIⅢ group was more than that in DMBA group(25 vs 10,P＜0.05).An significant elevation of 8-oxodG in epidermis was observed in 0.5 h[(1.67±0.17)/105 dG],1.0 h[(1.62±012)/105 dG],2.0 h[(1.66±023)/105dG], 3.0 h[(1.60±0.15)/105 dG],compared with 0 h[(1.25±0.11)/105 dG],being significant(P＜0.05).Conclusion tumor promotion due to DMAv administration is mediated by DMAⅢ through the induction of oxidative stress.

AIM:To evaluate the recovery about the visual cortex function of stereopsis in anisometropic amblyopia after regular amblyopia treatment 6, 12 and 18mo with blood oxygenation level dependent - function magnetic resonance imaging techniques ( BOLD-fMRI) .
METHODS: In this study, self-controlled study before and after treatment was used, and blocks-designed fMRI was performed on 11 children which was the first phase of research for amblyopic treatment. Functional MRI data were processed by using SPM8 which based on the Matlab 7. 12. 0. 635. Through the hypothesis drive method, the differences range of activated area in each group were compared by before and after amblyopia treatment matched t-test.
RESULTS: The functional area that was left occipital lobe (BA18), middle occipital gyrus (BA19), limbic lobe (BA19), lingualis gyrus of the right occipital lobe (BA17) and the bilateral parietal lobe ( BA7 ) expanded after amblyopia treatment 6, 12mo, compared those treatment phase, mean t value was 1. 5762, 1. 6856 respectively (P<0. 001). However, the difference of activated intensity was lower after 18mo, mean t value was 1. 1473 (0. 001 CONCLUSION: In children anisometropic amblyopia, the speed of function reconstruction about visual cortical functional mediating stereopsis increase slowly after amblyopia treatment 1a.

This study was to investigate the permeability and absorbability of capsaicin cubosome across abdominal skin of the SD rats in vitro. Diffusion of capsaicin cubosome and cream was performed with the modified Franz diffusion cell technique. The capsaicin cubosome showed no enhancement of skin permeation within 24 hours. However, the deposition amounts of capsaicin in the rat skin in the cubosome group was markedly higher than those in the commercial cream group (P < 0.01). Cubosome showed excellent characetristic of skin-targed which could be a good carrier for the local transdermal drug delivery system.

Background Oxidative stress plays an important role in the pathogenesis of diabetic complications.Peroxiredoxin 6(Prx6) is a doubly-functional protein.and its ability to eliminate phospholipid hydroperoxides is essential. Objective The aim of this study was to investigate the dynamic expression of Prx6 in the retina of streptozotocin(STZ)-induced diabetes and explore its correlation with the progression of diabetic retinopathy. Methods Diabetes was induced by an intraperitoneal injection of streptozotocin(STZ)in 48 clean Wistar rats.The rats were sacrificed at 1,2,and 4 months after the injection of STZ,and expressions of Prx6 protein and Prx6 mRNA in the retina was determined by immunohistochemistry and reverse transcription polymerase chain reaction.Another 12 matched normal Wistar rats were used as the control group. Results The resuh of immunohistochemistry showed that Prx6 protein was expressed in the cytoplasm of the outer nuclear layer(ONL)and inner nuclear layer(INL)in normal rats,and low expression of Prx6 protein was observed in the ganglion cell layer (GCL).In the first month,Prx6 protein was strongly expressed in the INL and the ONL of diabetic rats.However.two and three months after STZ administration,the expression of Prx6 protein was absent in the retina,showing a considerable difference among different course groups(F=22 967.63,P＜0.05).Furthermore,the expression trend of Prx6 mRNA in the retina was similar to that of the Prx6 protein with a significant difference among different course groups(F=942.84,P＜0.05). Conclusion It is conceivable that normal maintenance of Prx6 expression may be important to the prevention of diabetic retinopathy.We hypothesize that oxidative impairments in the retina that develop over time may partly contribute towards the development of retinal dysfunction,which eventually leads to retinal degeneration during the progressive phase of STZ-induced diabetes in adult rats.

ObjectiveTo investigate the expression of MUC1 in thyroid cancer and benign thyroid diseases (nodular goiter and adenoma) and its clinical significance. Methods The expression level of MUC1 was examined by immunohistochemical analysis with MUC1 monoclonal antibody in 68 samples of thyroid carcinoma and in 18 samples of benign diseases and 10 normal thyroid tissues. Results Immunohistochemical analysis showed positive expression of MUC1 in 51 out of 68 cases of thyroid cancer, in 4 out of 18 cases of benign thyroid diseases and 1 out of 10 normal control thyroid tissue, with a difference statistically significant between the malignancy and benign and normal control (? 2=17.20,P0.05).Conclusion The over-expression of MUC1 in thyroid cancer may act as diagnostic markers of thyroid carcinoma.

Objective To investigate the expression of MUC1 in primary liver carcinoma (PLC) and in cirrhotic liver tissue and its clinical significance in the diagnosis and immuotherapy of PLC. Methods The expression of MUC1 was examined by immunohistochemical analysis in 43 samples of primary liver carcinoma (PLC) , incluing 34 samples of hepatocellular carcinoma (HCC), 9 samples of cholangiocarcinoma (CC) ;and 12 samples of cirrhotic liver tissue and 6 samples of normal liver tissues. Results Immunohistochemical analysis showed over- expression of MUC1 in PLC , which aberrantly localized in the cancer cell membrane; while expression of MUC1 was detected only in 2 cirrhotic liver samples,and no expression in normal liver tissue. The expressional level of MUC1 in PLC was significantly higher than that in cirrhotic and normal liver tissue ( P 0.05),but the expressional levels between with portal cancer emboli group and without portal cancer embloli group was significant difference( P
