Objective To identify the characteristics of hippocampal 3-dimensional MRI in patients diagnosed as having subtypes of amnestic mild cognitive impairment(aMCI)using hippocampal surfacebased analytic technique.Methods Fifry aMCI patients and 16 healthy controls who were equivalent in age and education(NC)were recruited.Every subiect carried out a 3-dimensional MRI scan.After the imaging data were acquired.the borders of the hippocampus were manually traced in coronal vlew using the software of InsightSNAP1.4.1. Hippocampal volume was computed automatically and statistically analysed.Hippocampal 3-dimension MRI were transformed into 3-dimension parametric surface mesh models of 400×200 prids.Hippocampal radial distance measures which was the distance from the surface point to the central axis were statistically compared between two groups.The radial atrophy significance maps were acquired and adjusted for multiple comparisons.Hippocampal morphological difference maps of aMCI in contrast with NC were acquired.Results The average normalized volume of left hippocampus were(3247.5±600.2)mm3 in aMCI patients and(3467.9±451.3)mm3 in NC subjects.The average normalized volume of right hippocampus were(3416.8±699.1)mm3 in aMCI patients and(3469.1±358.9)mm3 in NC subjects.Comparison of hippocampal volume did not differ significantly between aMCI patients and NC subjects(t=1.161,P=0.255;U=0.178,P=0.859).By using hippocampal surface-based morphologic analytic technique,3-dimension hippocampal morphological difference maps between two groups were acquired,showing significant atrophy on the lateral and inferior hippocampal surface which corresponded to CA1 and subiculum hippocampal subfields bilaterally in aMCI patients compared with NC subjects. Conclusions aMCI patients do not have significant volume loss in the hippocampus. Through hippocampal surface-based morphologic analyses, partial regional atrophy of hippocampus at some degree is found, mainly localizing in the lateral and inferior hippocampal regions which correspond to CA1 and subiculum hippocampal subfields bilaterally in aMCI compared with NC. These results may reflect the early image marker in aMCI.

Objective To investigate the value of platelet, serum sodium and serum creatinine levels in the prognosis of patients with liver failure. Methods The clinical data of 155 patients with liver failure were retrospectively analyzed, and the patients were divided into improvement survival group (87 cases) and deterioration died group (68 cases) according to the prognosis. The hospitalization time of every patient was divided into 4 roughly equal time period, and observed at 5 points of time:T1-T5. The levels and abnormal rates of platelet, serum sodium and serum creatinine were compared. Results The T3 - T5 serum creatinine levels in deterioration died group were significantly higher than those in improvement survival group: (102.14 ± 75.67) μmol/L vs. (78.21 ± 26.68) μmol/L, (116.45 ± 110.64)μmol/L vs. (78.77 ± 29.25) μmol/L, (161.43 ± 153.23) μmol/L vs. (76.40 ± 27.26) μmol/L, and the T1 - T5 serum sodium and platelet levels were significantly lower than those in improvement survival group:(135.05 ± 6.24) mmol/L vs. (137.52 ± 5.26) mmol/L, (137.01 ± 4.99) mmol/L vs. (139.00 ± 3.89) mmol/L, (134.80 ± 16.74) mmol/L vs. (139.15 ± 3.77) mmol/L, (134.40 ± 11.69) mmol/L vs. (138.30 ± 8.75) mmol/L, (133.30 ± 8.93) mmol/L vs. (139.01 ± 9.10) mmol/L, and (122.46 ± 72.59) × 109/L vs. (149.70 ± 71.70) ×109/L, (110.18 ± 65.10) × 109/L vs. (152.09 ± 82.79) ×109/L, (107.32 ± 70.49) ×109/L vs. (169.32 ± 100.65) ×109/L, (97.06 ± 58.15) ×109/L vs. (183.57 ± 112.68) ×109/L, (94.66 ± 57.00) × 109/L vs. (191.36 ± 118.64) ×109/L, and there were statistical differences (P<0.05). The abnormal rates of T3-T5 serum creatinine, T2 - T5 serum sodium and T1 - T5 platelet in deterioration died group were significantly higher than those in improvement survival group, the serum creatinine: 22.06%(15/68) vs. 6.90% (6/87), 27.49% (19/68) vs. 8.05% (7/87) and 42.65% (29/68) vs. 10.34% (9/87), the serum sodium: 32.35% (22/68) vs. 13.79% (12/87), 39.71% (27/68) vs. 14.94% (13/87), 48.53% (33/68) vs. 12.64%(11/87) and 60.29%(41/68) vs. 11.49%(10/87), the platelet:45.59%(31/68) vs. 21.84%(19/87), 55.88% (38/68) vs. 24.14% (21/87), 54.41% (37/68) vs. 25.29% (22/87), 55.88% (38/68) vs. 21.84%(19/87) and 61.76% (42/68) vs. 20.69% (18/87), and there were statistical differences (P<0.05). Abnormal rate of platelet was highest in each time point. Conclusions In the course of pathological changes in deterioration and dead patients, the platelet is the first and most easily affected compare with serum sodium and serum creatinine; the platelet may be a sensitive marker for predicting clinical outcome in patients with liver failure.

Objective To observe the image characteristics ofmultispectral scanning laser imaging (MSLI) and OCT in patients with pregnancy induced hypertension syndrome (PIHS).Methods A total of 112 patients (224 eyes) of PIHS patients diagnosed in Obstetrics Department of Tianjin First Central Hospital from May 2016 to May 2017 were included in this study.The average age of the patients was 27.00±2.14 years.The average course of the disease was 15.00 ±8.27 days.There were 174 eyes in 87 patients of blurred vision,dazzling and visual fatigue consciously.All patients performed BCVA,direct ophthalmoscope,B ultrasound,confocal scanning laser Ophthalmoscope (cSLO) and spectral-domain OCT (SD-OCT).SD-OCT was performed with Spectralis HRA+OCT from Heidelberg Company in Germany to acquire tomographic images.Using Herdelberg's colorful program (MultiColor) based on cSLO and operating in accordance with standard methods,one scan simultaneously obtained blue light reflection based on 488 nm,green light reflection based on 515 nm,and infrared reflection based on 820 nm,synthesis to MSLI.Fundus abnormalities were classified into arterial spasm (stage Ⅰ),arteriosclerosis (stage Ⅱ),and retinopathy (stage Ⅲ).OCT examination was divided into normal and abnormal cases according to the abnormality of retinal morphology and thickness.Results Of the 224 eyes,68 eyes (30.36%) showed normal fundus examination and 156 eyes (69.64%) showed abnormal fundus performance.Among them,28 eyes were stage Ⅰ (17.95%);40 eyes were stage Ⅱ (25.64%);88 eyes were stage Ⅲ (56.41%).Thirty-six eyes (16.07%) showed normal fundus and 188 eyes (83.93%) showed abnormal performance with OCT.Of the 188 eyes with abnormal fundus performance,86 eyes (45.74%) had retinal neuroepithelial serous detachment;56 eyes (29.79%) had RPE detachment;optic disc edema,bulge,and local reflexes in the retinal nerve fiber layer were enhanced and/or the thickness increased in 46 eyes (24.47%).In MSLI,48 eyes (21.43%) showed normal fundus;176 eyes (78.57%) showed abnormal performance.Retinal edema was showed in green on MSLI,serous retinal neuroepithelial layer detachment,RPE layer detachment,retinal nerve fiber layer thickening,accompanied by changes in local retinal structure.The higher the degree of bulge,the darker the color.Consistent with the range of retinal edema revealed by SD-OCT.Conclusions MSLI and SD-OCT images show highly consistent lesions in PIHS patients.MSLI can more clearly show superficial and deep retinal lesions.
