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.

Objective:This study aimed to establish a mouse model of breast cancer by inoculating human breast cancer cells into mice with normal immune function. Methods:Forty female BALB/C mice were randomized into four groups, with 10 mice in each group. The four groups were established according to the dosage of cyclophosphamide and prednisone, namely, the control group, low dose group, medium dose group, and high dose group. The mouse models of breast cancer were established by injecting human breast cancer cells into the fat pad of the right second breast of mice in the groups. Mice in the four groups were observed based on the time of tumorigenesis, rate of tumor formation, tumor imaging and pathological features, and metastasis of vital internal organs. Results:In the high dose group, the time of tumor formation was lower than that of the other groups, but the rate of tumor formation was high. Some visceral metastases occurred in the mice. By contrast, the medium dose group revealed completely opposite results. No death and tumor formation in both the control and low dose groups were reported. Conclusion:A human breast carcinoma model in mice was successfully established. Using this model, the onset and development of breast cancer could be much better imitated in the normal immune system of mice.

Objective To investigate the relationship between serum follicle stimulating hormone (FSH), luteinizing hormone (LH), prolactin (PRL) and clinicopathological features and prognosis of serous ovarian cancer retrospectively. Methods A total of 73 patients with serous ovarian cancer treated in the Department of Obstetrics and Gynecology of Tianjin Medical University General Hospital from January 2000 to December 2015 were included in this study. The relationship between serum FSH, LH, PRL and clinicopathological features was analyzed by Mann-Whitney U method. Kaplan-Meier (K-M) method was used to analyze survival rates of patients with different clinical features. Multivariate Cox proportional hazards regression analysis was used to analyze prognostic factors of serous ovarian cancer patients. Results The mean concentrations of serum FSH and LH were significantly higher in the>50 year-old group than those in the<50 year-old group (P<0.05). The mean concentrations of FSH and LH were significantly higher in menopause group than those in non-menopause group (P<0.05). There were no significant differences in serum levels of FSH and LH in patients with other different clinicopathological features (P>0.05). There was no significant correlation between serum PRL concentration and clinicopathological features (P>0.05). Analysis results showed that poor prognosis of patients was related with high serum levels of FSH (>40.13 IU/L), PRL (>14.96 μg/L) and FIGO stage (Ⅲ+Ⅳ) (P<0.05). There was no significant correlation between serum LH concentration and prognosis (P>0.05). COX regression analysis showed that the serum PRL>14.96 μg/L was risk factor for prognosis of serous ovarian cancer [HR(95%CI): 3.530(1.180-10.557),P=0.024]. Conclusion The serum levels of FSH and LH are significantly increased in postmenopausal women than those in menopause women. The serum level of PRL is correlated with the prognosis of serous ovarian cancer.

Objective To develop a promising type of radiation dosimeter based on doped hydroxyapatite,and to study the stability of dosimetric characteristics indepth.Methods The samples prepared by stereotyping techniques were stored under different temperatures,humidity and illumination conditions after 60Co γ-ray irradiation.Electron spin resonance (ESR) technique was used to quantitatively measure the radiation-induced free radical signal.Results The signal change was less than 3% when the dosimeter was preserved at 4℃ or room temperature within 3 months in the experiment.At 40℃,the signal changed by about 13%,but at room temperature with the humidity less than 36%,the signal changed less than 2%.The change rose to about 8% when humidity was 76%.However,no significant decay of signal strength occurred at relatively high temperatures and under high humidity conditions.When the samples were stored under average illumination of 1600 lux or in a light-resistant container,the signal changes were less than 3.8% or 3.4% respectively.Long-term stability inspection at room temperature suggested a signal change within 4.8%.Conclusion The dosimetric properties of the material don't change significantly below room temperature in a natural environment and exhibit good stability over long-term storage.The free radical signal is not influenced drastically by relatively strong light exposure.However,a high temperature or a highly humid environment may have some effect on the measurement process,which should be taken into consideration in further applications.

AIM: To investigate the effect of interleukin-13 (IL-13) on cell proliferation and interleukin-6 (IL-6) production in mesangial cells. METHODS: Cell proliferation was tested by MTT method. The protein synthesis of IL-6 in mesangial cells was measured by ELISA. The expression of IL-6 mRNA in mesangial cells was evaluated by RT-PCR. RESULTS: IL-13(1 ?g/L-100 ?g/L) inhibited the proliferation of mesangial cell in a dose-dependent manner. Both mRNA and protein of IL-6 in mesangial cells were increased significantly in the presence of LPS and this increase could be reversed by IL-13 (1?g/L-100?g/L). However, this increase could not be reversed by IL-13 if the dose was lower than 0.1?g/L and if the mesangial cells were cultured in 5% FCS RPMI1640. CONCLUSION: IL-13 could inhibit IL-6 expression induced by LPS in mesangial cells . We suggested that IL-13 may be an inhibitory cytokine in the regulation of the mesangial cell proliferaltion and inflammatory reaction in glomerulonephritis.

Objective　To determine the origin of human influenza A (H9N2) virus and the relationship among H9N2 strains isolated from different hosts, on the basis of molecular biology. Methods　Viruses were passed in embryonated hen eggs, and virion RNA was extracted from allantoic fluid and reverse transcribed to synthesize cDNA. cDNA was amplified by PCR and the PCR product was purified with a purification kit. Afterwards RNA sequence analysis was performed by dideoxynucleotide chain termination and a cloning method. Finally, phylogenetic analysis of the sequencing data was performed with MegAlign (version 1.03) and Editseg (version 3.69) softwares. Results　The amino acid sequences at the cleavage site between HA1 and HA2 domains of H9N2 viruses isolated in China are R-S-S-R. One pigeon strain contains seven potential glycosylation sites on the HA protein molecule, while all others have eight. There are 2 to 15 differences of amino acid sequences distributed at 24 different positions on the HA protein molecules among six H9N2 viruses. The H9N2 viruses with multiple lineages of HA genes were co-circulating in China recently. Conclusion　The highest possibility is that human influenza A (H9N2) virus was derived from Chicken H9N2 virus, and not derived from pigeon H9N2 virus. However, it is still unknown whether the H9N2 virus could transmit from person to person. The H9N2 viruses with multiple lineages of HA genes are co-circulating in China.

Objective To understand health seeking behavior and its influential factors to reproductive tract infections (RTIs) on women at reproductive age in the rural areas. Methods 54 540 fertile women aged 15-49 were surveyed by a stratified-cluster-random sampling method and gynecological examination were conducted in two steps: converging at the clinics, and then visiting their households, later, 31 624 women who had at least one RTI symptom were chosen. Results Among all the women at reproductive age, the rate of having at least one RTI symptom was 59.8% with the means of RTI symptom as 1.66±0.89. 15 989 women went to see doctors out of the 31 624 women who had RTI symptoms, with a proportion of 50.6 %. The results of logistic regressy showed that those women whose husbands having higher education level, higher income, more RTI symptoms and better knowledge on RTI were more easily to go to the hospitals. However, those women whose husbands working out of the county, having older first bearing age and more numbers of pregnancy were less likely to go to the hospitals. Reasons that refrained them from going to see a doctor would include: 2137(13.7%) did not know that RTI was a disease; 7443(47.6%) of them thought that every woman were bound to have at least one symptom and it did not matter; 1629 (10.4%) of them felt shameful; 349 (2.2%) learned that the diseases were incurable; 975 (6.2 % ) felt the cost of treatment was too expensive; 2101 (13.4 %) had no time; 1001 (6.4 %) would treat themselves through buying medicines over the counter. Conclusion RTI symptoms were quite prevalent among women at reproductive age but the rate of seeing a doctor was low and caused by multi-factors. Health education and gynecological census in increasing the curable rate of RTIs should to be strengthened.
