Urinary calculus is a common disease of urinary system.With the improvement of people's living standard,the incidence rate of urinary calculus increased year by year.Compared with other methods,spiral CT has a great advantage in the diagnosis of urinary calculus.The current commonly used examinations including spiral CT plain scan,low dose spiral CT scan,CT urography,and dual source dual energy CT imaging.The advantages and characteristics of different types of CT are analyzed and compared,which is helpful for clinicians to choose the most proper examination,to make the most of the advantages of various checks,so as to improve the accuracy of diagnosis and effectiveness of treatment.

Objective To investigate mechanism of chronic bacterial prostatitis (CBP) causes increased oxidative stress and oxidative damage in the patients. Methods Seventy CBP patients (CBPPs) sampled randomly, and seventy healthy adult volunteers(HAVs) sampled randomly, were enrolled in a case-control study, in which the levels of nitric oxide (NO), vitamin C (VC), vitamin E (VE), and (-carotene ((-CAR) in plasma, as well as the level of malondialdehyde (MDA), and the activities of superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GPX) in erythrocytes were determined by spectrophotometry. Results Compared with the average values of NO and MDA in the HAVs group((378?33)nmol/L和(28.6?4.4)nmol/g?Hb),the average values in the CBPPs group ((426?31)nmol/L and (34.7?4.7)nmol/g?Hb)were significantly increased, while VC, VE, ?-CAR, SOD, CAT, and GPX in the CBPPs group((47.4?11.6)?mol/L,(18.1?4.8)?mol/L,(1.4?0.4)?mol/L, (1 912?221)U/g?Hb, (254?67) K/g?Hb and (25.0?5.0) U/g?Hb) were significantly decreased compared with the average values in the HAVs group((55.1?13.4)?mol/L、(25.7?4.5)?mol/L、(1.7?0.5)?mol/L、(2 081?222)U/g?Hb、(294?77)K/g?Hb和(28.8?5.1)U/g?Hb)).The partial correlation analysis between the course of disease and the said each parameter for 70 CBPPs while controlling for the age suggested that with prolonged course of disease the values of NO and MDA were gradually increased (rNO=0.480 1,rMDA=0.436 4,P

12-18 years old).In each age group,children were classified according to their genders.Diffusion tensor imaging(DTI)was performed in all the children's heads.Then the angles formed by splenium corporis callosi and occipital forceps were measured in fractional anisotropy maps.All the data were analyzed statistically.Results 1.The females in infant group had the larger angles formed by splenium corporis callosi and occipital forceps.With the age increasing,the average values of angles tended to decrease gradually.But in some age groups,the average values in some cases tended to increase before it decreased.2.A statistically significant sex difference was found in infant group.In young child group,pre-school age group and adolescence group,such difference was found in angles formed by occipital forceps.Only in young child group,difference in the maximum angles of splenium corporis callosi was found.3.There was a significant difference between age groups in the angles formed by sides of occipital forceps and the minimum angles of splenium corporis callosi through one-way analysis of variance.4.The angles of occipital forceps and the minimum angles of splenium corporis callosi both had a negative correlation with ages.They both had a linear regression to ages.But,there was no correlation between the maximum angles of splenium corporis callosi and ages.Conclusions Sex differences might exist in the angles formed by both sides of occipital forceps and splenium corporis callosi.The angles formed by sides of occipital forceps and parts of angles of splenium corporis callosi might decrease when the age increases.Diffusion-weighted technology can be used to study the age and sex difference in angles formed by splenium corporis callosi and occipital forceps in children.

Dystonia is a common movement disorder characterized by abnormal gestures and involuntary movement as a result of incoordinate contraction of agonistic and antagonistic muscles.The underlying pathogenesis is very complicated and there are various clinical manifestations.The recent findings in genetics and clinical features of primary dystonia,dystonia-plus syndrome and heredodegenerative dystonia are introduced in this paper.

AIM: To compare the clinical results of suture method and partial eyelash resection treating for pediatric eyelid trichiasis, and screen an effective method for the treatment of pediatric lower eyelid trichiasis.
METHODS: Fifty-six cases of pediatric patients with lower eyelid trichiasis were randomly divided into a control group and an observation group in accordance with the method of drawing lots, and each group was 28 cases. The control group was treated with suture method, and the observation group was treated with partial eyelash resection. The clinical efficacy, patient satisfaction before and after treatment, and the incidence of complications were compared.
RESULTS:(1) The clinically total effective rate was 74%of the control group, which was 89% of the observation group, and there were statistical differences of the clinical efficacy between the two groups ( P<0. 05 ); ( 2 ) the satisfaction scores were (3. 89±1. 22) points and (6. 27±1-86) points of the the control group before and after treatment, which were ( 4. 00±1. 34 ) points and ( 8-95±2-34) points of the observation group, and there were statistical differences of the two groups before and after treatment (P<0. 05), and the scores of the observation group were higher than that of the control group ( P<0-05);(3) complications such as swelling and stitches off appeared in both groups, and the rate was 21% in the control group, which was 11% in the observation group, and there were statistical differences between the two groups (P<0. 05).
CONCLUSION: The treatment of children with lower eyelid trichiasis, suture method is simple and can be performed under local anesthesia in collaboration with children, but with a higher relapse rate, some patients required reoperation;partial resection of eyelashes can be more thoroughly solve the problem of pediatric eyelid trichiasis with low recurrence rate, but children need to be under general anesthesia with some of big risk. So partial resection of eyelashes is unsuitable for using in clinical practice widely and can be used in special cases.

OBJECTIVETo analyzed the relationship between lumbar endplate Modic area changes rate and low back pain by measuring MRI T2 sagittal image of lumbar endplate Modic area changes rate.

METHODSFrom December 2011 to June 2012,70 patients with low back pain in operation were evaluated on pain by VAS and function by JOA,and examined by MRI including 39 males and 31 females with an average age of (51.00 +/- 11.89) years ranging from 29 to 72 years old. Among them, 54 cases had lumbar endplate Modic changes involving 15 cases in types Modic I ,21 cases in type Modic II, 11 cases in type Modic III ,mixed type Modic in 7 cases (eliminated for too few cases). Modic area changes and corresponding vertebral area were measured on MRI T2 median sagittal. The areas of two ways were compared to yield the rate of changes for Modic, for multisegmental Modic changes to calculate the total ratios. A correlation was observed among JOA, VAS and the rate of Modic changes.

RESULTSThe correlation coefficient of change rate of Modic I with JOA score was r = -0.308, P = 0.048 < 0.05, there was a negative correlation;the correlation coefficient of change rate of Modic I with VAS scores was r = 0.428,P = 0.021 < 0.05, there was a positive correlation. The correlation coefficient of change rate of Modic II with JOA score was r = -0.375, P = 0.043 < 0.05, there was a negative correlation;the correlation coefficient of change rate of Modic II with VAS score was r = 0.352, P = 0.041 < 0.05, there was a positive correlation. The area change rate of Modic III had no significant correlation with low back pain degree (P > 0.05).

CONCLUSIONModic I and II area changes rate of of patients with low back pain is closely related to the degree of pain low back pain, Modic III area changes rate is not significant correlated to the degree of lower back pain.
