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.

OBJECTIVETo investigate the prevalence and distribution of HCV genotypes and the clinical effect of interferon-alpha combined with ribavirin treatment in chronic hepatitis C patients in Kunming.

METHODS60 patients were divided into two groups based on drug therapies: PEG-interferon-a plus ribavirin treatment group for HCV 1b and interferon-a plus ribavirin treatment group for non-HCV-1b. Serum ALT levels and HCV RNA quantitations of the patients were detected during treatment and follow-up.

RESULTSThe HCV genotypes of 60 patients were determined by type specific probe assay, and five different types were found. Their overall prevalence were 21.7% for type 1b, 5% for type 2a, 16.7% for type 3a, 48.3% for type 3b, and 8.3% for type 6a. Sustained viral response rates for PEG-interferon treatment group were 46.1%, for interferon treatment group were 74.4%. The abnormal rate of serum ALT after the treatment had no significant difference between HCV-1b and non-HCV-1b patients (P>0.05). All patients with early viral responses got sustained viral response.

CONCLUSIONHCV-3b is the most dominant genotype in Kunming. The effect of PEG-interferon-a plus ribavirin treatment for genotype 1b is unsatisfactory. The early viral response is a good predictor for the responses to antiviral therapy in chronic hepatitis C patients.

Objective No related training experience, no systematic training before military training, psychological negative emotions(tension and anxiety) and low frequency of physical activities(less than three times a week) have been considered as crucial risk factors of high intensive military training induced acute kidney injury.This paper aims to discuss whether these risk factors can be used for screening high risk groups.Methods Soldiers were divided into 5 groups based on the questionnaire survey:Group1 had no risk factor, Group2 had 1 risk factor, Group3 had 2 risk factors, Group4 had 3 risk factors, and Group5 had 4 risk factors.Urine samples were collected after 6 h and 24 h of 5 km armed military training.Kidney injury indicators were compared such as urine protein, urine occult blood test, urine micro-albumin ( mALB) , urine N-acetyl-β-D-glucosaminidase( NAG) among different groups.Results As the risk factors increased, the incidence of positive urinary protein 6 h after training increased (x2 =101.8,P<0.001),and the levels of mALB and NAG of urine samples were elevated as well.The analysis among moderate and high risk groups(Group3-5) showed that the levels of mALB and NAG of urine samples 24 h after training increased with the number of risk factors.The mean value of these injury indicators reached to the maximum in Group 5.Conclusion No related training experience, no systematic training before military training, psychological negative emotions( tension and anxiety) and low frequency of physical activi-ties(less than three times a week) are independent risk factors of high intensive military training induced acute kidney inju-ry,which can be used for screening high risk individuals during training.

Objective To study the influence of cochlear implantation on residual hearing in children .Methods Behavioral audiometry were performed pre -implant and 3~21 months post -implant on thirty -four cochlear implant recipients with severe to profound hearing loss .According to follow -up time ,they were divided into 2 groups which were Group A(3~12 months ,21 cases) and Group B(≥13 months ,13 cases) .The thresholds at 250 Hz ,500 Hz ,1 000 Hz and 2 000 Hz were analyzed .Results There were 25 out of 34 patients (73 .53% ) had partial residual hearing after cochlear implantation .Comparing to the hearing loss pre -operation and post -operation , which were most obvious at 500 Hz ,followed by 250 Hz ,1 000 Hz ,2 000 Hz (P<0 .05) ,and there were significant different among different frequencies .There was significant difference at different frequencies at hearing loss thresh-olds only in Group A .But there was no significant difference in Group B .With the prolonged time after the cochlear implantation ,residual hearing at all frequencies showed a trend of recovery .Conclusion The residual hearing could be partial preserved after cochlear implant in pediatric patients with severe to profound hearing impaired ,the residu-al hearing at lower frequencies (250 Hz ,500 Hz) were less affected than those at higher frequencies .With the pro-longed time after the cochlear implantation ,the residual hearing showed a certain degree of recovery .

The present study aimed to investigate the effect and the mechanisms of Bu-zhong-yi-qi-tang (BZYQ) on Spleen-Qi deficiency rat's model using nuclear magnetic resonance (NMR) metabolomics and multivariate statistical analysis methods. The rat Spleen-Qi deficiency model was established as follows: oral administration of Radix Rhei extract, loaded swimming and starvation for 24 h. The body weight and motor behavior of the rats were measured and recorded once a week. BZYQ could significantly improve body weight and behavioral of Spleen-Qi deficiency model rats compared with the model group (P < 0.05, 0.01). After drug administration, the changes in the levels of endogenous metabolites in the spleen including decreasing lactate, taurine and hypoxanthine, increasing glutamate and scyllo-inositol compared with the model group. The metabolomics approach is an effective tool for the investigation of the pharmacologic mechanism of BZYQ and it is helpful to further research.

Objective To investigate the effect of tea polyphenols (TP) on renal damage in rats model induced by D-galactose. Methods Rats were injected with D-galactose (150 mg/kg?d),ip for 8 w,to induce renal damage. From the 3rd week,TP (150,75,37.5 mg/kg?d),aminoguanidine (150 mg/kg) and vitamin E (150 mg/kg) were administered with D-galactose for 6 w. After treatment,fasting blood glucose and 2 h blood glucose in oral glucose tolerance test were measured. The levels of HbA1C and fructosamine in serum,the activity of aldose reductase and content of advanced glycation end products (AGEs) in plasma and in kidney tissues and the activity of SOD,GSH-Px,and the contents of MDA in kidney tissues were measured,and 24h urinary protein,blood urea nitrogen (BUN) and serum creatinine (Cr) were detected. The apoptosis of renal cells were detected by flow cytometer. Results After treatment of D-galactose for 8 w,2h glucose level in oral glucose talerance test was increased significantly,the activity of aldose reductase and the content of AGES were increased significantly in blood. The levels of AGEs and MDA in renal tissues were also enhanced significantly. However,the activities of SOD and GSH-Px decreased. Additionally,the contents of 24h urine protein,BUN,Cr and the apoptotic rate of renal cells were increased significantly. High and middle dose of TP could can decrease the activity of aldose reductase in red blood cells,and inhibit the formation of glycation products in model rats induced by D-galactose. Also,TP could enhance the antioxidative activities and decrease the contents of AGEs and MDA in renal tissues. Mesnwhile,24h urine protein,BUN and Cr and the apoptotic rate of renal cells were increased significantly. Conclusion TP can inhibit glycation reaction induced by D-galactose and then protect renal from damage caused by glycation.
