Objectives:To investigate the changes of portal hemodynamics in patients with liver cirrhosis and its clinical value. Methods:Forty patients with liver cirrhosis and twenty healthy volunteers as controls were involved in this study.The max diameters,mean flow velocity,flow rate and congestion index(CI) of the portal vein trunks(PV) and splenic veins(SV) were detected by Color Doppler Ultrasound in all subjects. Results:The PV diameters(PVD), PVT flow rate(PVF), PVCI and SV diameter(SVD),SV flow rate(SVF),SVCI were significantly highter in patients than in controls( P

Objective To investigate the clinical value of of procalcitonin detection in neonatal necrotizing enterocolitis (NEC).Methods Sixty cases eligible NEC infants were randomly divided into observation group and control group(n=30 each group).All the infants were divided into Ⅰ grade group(19cases),Ⅱ-Ⅲ grade group(41 cases) according to NEC classification.All infants received PCT detection after NEC diagnosis.The observation group received antibiotic treatment base on the serum PCT levels.The control group received antibiotic treatment according to treatment routine and physician's clinical experience.Results PCT increased in 28 (46.7％) of the 60 NEC infants.In the Ⅰ grade group and Ⅱ-m grade group,the proportion of PCT increased cases were 26.3％,61.3％ respectively,and the PCTmax in PCT positive cases were (0.81±0.25) μg/L,(1.76±0.89) μg/L respectively,the differences were signifiacnt(x2 =4.627,t=-2.608,P＜0.05).The time of antibiotic usage in observation group was significantly less than that in control group ((4.9±3.0) d vs.(8.6±2.5) d,t=-3.645,P＜0.01).The fasting time and the cure time of the two groups had no significant difference (P＞ 0.05).Conclusion PCT detection can help to understand the cause and severity of NEC.Using antibiotics according to PCT levels can reduce the time of antibiotic usage without affecting the effect of the NEC treatment.

Objective To investigate the role of expression in the differential diagnosis of thyroid follicular carcinoma and follicular variant of papillary carcinoma. Methods Seventy cases of thyroid lesions (including 15 cases of follicular adenomas, 15 cases of adinomatous goiters, 30 cases of papillary carcinomas and 10 cases of follicular carcinomas) were collected, and CD10 expression was detected by means of immunohistochemistry in above thyroid lesions. Results Seven of 9 cases of follicular variant of papillary carcinoma were CD10 positive (77.8), and 8 of 10 cases of follicular carcinoma were CD10 positive (80.0). However, CD10 was negative in all cases of non-follicular variant of papillary carcinoma, follicular adenoma, adinomatous goiter and normal thyroid tissue. Conclusion The detection of CD10 expression is useful to the differential diagnosis of thyroid follicular carcinoma and follicular variant of papillary carcinoma.

Objective To study the emmetropization in guinea pig eyes during the normal development from birth in order to provide theoretical basis to use guinea pigs as model for research on near-sightedness.Methods Sixty-four guinea pigs were assigned to 8 groups (n=8,4 male/4 female).Each group underwent a series of ocular examinations at one of the 8 time-points (0,1,2,3,5,7,9 and 11 weeks),including refraction(R),radius of corneal curvature (RCC),depth of anterior segment(AS),thickness of crystalline lens (CL),length of vitreous chamber (VC)and axial length (AL).Pooled results from both eyes of the same animals with mixed sexes can be used for further assessment of the emmetropization with the associated biometrical changes of the eye.Correlations were made between RCC,AS,CL,VC,AL and R. Results There were no significant differences between the right eye and left eye or between male and female in results of all the examinations. The refraction at birth was (+5.25?0.22 )D in guinea pigs.This value rapidly decreased during the first 3 weeks,approaching(+1.34?0.61) D by 11 weeks.There was no significant difference in refraction between 9 and 11 weeks (P= 0.215). The RCC was (3.23?0.01) mm at birth,AS was (1.20?0.00) mm at birth,CL was (2.72?0.02) mm at birth and VC was (3.27?0.01) mm at birth,they increased within the first 3 weeks despite a transient decrease in the RCC within the first week.Such an increase continued except the AS which became constant after 3 weeks.The VC was more correlated to the emmetropization (r=-0.818,P
