Objective To discuss the changes of clinical pathology and CT morphology in child patients with cerebral palsy.Methods CT images in 84 cases with cerebral palsy were retrospectively analyzed.Results In 84 cases,60 patienes have abnomal findings of CT scanning(71.5 per cent).There are 4 cases of diffuse encephalatrophy,20 cases of Localized encephalatrophy,16 cases of Periventricular atrophy,26 cases of encephalomalac focus,6 cases of intermodiate part of abnormality,4 cases of cerebrospinal fluid retention,2 cases of porencephaly,2 cases of arachnoid cyst,18 cases in this group were encephalatrophy unite others.Conclusions Cerebral palsy has some characteristics on CT,which are inadequate cerebrospinal capability and development abnormity.

High myopia is a common blinding eye disease with high specificity and population genetic heterogeneity.It has emerged as a major public health concern,which is often accompanied by many severe associated comorbidities,including retinal detachment,cataract and glaucoma.While rarely effective treatment Is found so far.This article reviews recent advances in understanding genetic mechanism of high myopia,such as mode of inheritance,MYP locus and candidate genes.

Objective To observe the changes of plasma lipid,C-reactive protein(CRP) and fibrinogen(FIB) in patients with acute coronary syndrome(ACS)treated with low dose simvastatin.Methods One hundred and twenty patients with ACS were randomly divided into treatment group and control group with 60 cases in each.The patients in the control group were treated with conventional therapy,and those in the treatment group were treated with 20 mg simvastatin per day at the base of control group.The course of treatment was 2 months.Results In the treatment group,the levels of total cholesterol(TC),triglyceride(TG),low density lipoprotein cholesterol(LDL-C),CRP and FIB were decreased significantly and the level of high-density lipoprotein cholesterol(HDL-C) was increased after the treatment(all P0.05).Conclusion The levels of plasma lipid,CRP and FIB can be effectively regulated with the treatment of low dose simvastatin in patients with ACS.

Purpose To explore the application value of diffusion kurtosis imaging (DKI) in assessing brain injury in different clinical stages caused by carbon monoxide (CO) poisoning. Materials and Methods MR plain scan, diffusion weighted imaging (DWI) and DKI scans were performed in 26 patients with acute CO poisoning, 17 patients with delayed neuropsychologic sequelae (DNS), 15 patients with chronic phase, and 21 healthy volunteers (control group). The DKI parameter values in regions of interest among the four groups were compared, and the correlation between the values of each parameter and DWI apparent diffusion coefficient (ADC) value was analyzed. Results ①The mean kurtosis (MK) values in the area of pallidum in acute phase, DNS phase, and chronic phase were 1.51±0.15, 1.07±0.11 and 0.59±0.11, respectively; among which the MK value in acute phase was significantly higher than that in the control group (1.06±0.06, P<0.05), and the chronic phase was significantly lower than the DNS phase and the control group (P<0.05); compared with the control group, the MK in centrum semiovale and subcallosal zone was relatively higher in acute phase and DNS phase, lower in chronic phase, both showing the most significant increase in DNS phase (P<0.05). ②In each region of interest, the MK value and mean diffusivity (MD) all showed an increase after decrease. Among them, MD values in the area of pallidum in acute phase were significantly lower than those in DNS and control group (0.74±0.11 vs. 0.85±0.07 and 0.98±0.12, P<0.05), and the centrum semiovale and callosum were the smallest in DNS phase (0.67±0.09 and 0.80±0.05, respectively), significantly lower than that in the control group (P<0.05). ③The fractional anisotropy (FA) values of all regions of interest showed a progressive decrease in different clinical stages, in which pallidum and centrum semiovale were the lowest in chronic phase (0.19±0.04 and 0.22±0.03, respectively), significantly lower than those in DNS phase and the control group (P<0.05). ④There was a positive correlation between MD values and ADC values in different clinical stages of CO poisoning in each region of interest (P<0.01). Conclusion DKI can quantitatively evaluate the changes of brain gray matter microarchitecture after CO poisoning, which is helpful to understand the characteristics of brain injury in different clinical stages caused by CO poisoning from the microscopic level.
