Objective To analyze the image findings of renal tuberculosis and evaluate the merits and disad vantages of various imaging diagnostic methods, then choose the most sensitive one. Methods The KUB, IVP, AP and CT findings of 48 patients with renal tuberculosis which had been convinced by operations were evaluated and compared. Results The diagnosis rates of KUB and IVP were 41.7% (20/48), AP of 62.5 % (10/16), CT of 100 % (48/48). The characteristic findings of CT were multiple low density lesions, with "flower petals" shape gath-ered in sections. Conclusion CT has a great value for diagnosing renal tuberculosis.

Objective To analyze CT features of the pulmonary segment lesions.Methods The CT findings of 88 patients with pulmonary segment lesions were reviewed.The diseases included chronic pneumonitis(n=30),tuberculosis(n=24),lung cancer(n=34),all proved pathologically.Results Wedge-shape or cone-shape of lesions was demonstrated in most of cases.In chronic pneumonitis,the border of lesion was depression or straight without hilar mass and bronchus obstructed.Most lesion was isodensity and the air bronehogram could be found in some cases.In tuberculosis,the border was irregular or hazy with different density inside the lesion(cavity,calcification,bronchieetasis).Satellite-lesion and thickening of the pleura nearby were found commonly.In lung cancer,the hilar mass and pot obstructed bronchus were the characteristic,with the border evagination in some cases.According to the above,82% of the cases were diagnosed correctly.Conclusions Some relative specific CT manifestation existed in the pulmonary segment lesions caused by chronic pneumonitis,tuberculosis and lung cancer.But the CT of some patients were similar to each other,of which diagnosis must be based on pathology.

AlM:To evaluate the long-term efficiency and safety of overnight orthokeratology in myopia correction and control in adolescents.METHODS: Sixty-five myopia adolescents treated in our hospital from August 2011 to February 2012 were retrospectively analyzed and followed up to 2a. Among them, 35 cases ( 67 eyes ) wearing overnight orthokeatology were included as trial group, and 30 cases ( 60 eyes ) wearing spectacles were included as control group. The trial group were divided into 2 subgroup according the myopic grading in the initial visit:subgroup A(35 eyes,≤-3. 00D), B subgroup (32 eyes,>-3. 00D and ≤-6. 00D). ln the trial group, slit lamp, visual acuity, refraction, intraocular pressure, corneal tomography were collected before wearing overnight orthokeratology, 1d, 1wk, 1month, 3mo, and every 6mo after wearing overnight orthokeratology , with axial length, corneal thickness, anterior chamber depth, corneal endothelial cell count, abjective refraction and tear film were also collected before and 2a after wearing overnight orthokeratology. ln the control group, slit lamp, visual acuity, refraction and intraocular pressure were collected before wearing and 2a after wearing spectacles. Paired t test were used to compare the intragroup difference. One-way analysis of variance ( ANOVA) was used to compare the differences among the groups. P<0. 05 was considered statistically significant.RESULTS: The uncorrected visual acuity of the trial group was improved obviously after wearing Orthokeratology Lens 1d, the visual acuity of a group patients improved more significantly. The corneal curvature ( including vertical curvature and horizontal curvature ) of the trial group became more flat after wearing Orthokeratology Lens 2a and stopped 2 wk; The length of ocular axis was also increased, the growth rate of B group (0.33±0.31)mm was lower than that of group A (0. 43±0. 25)mm; Subjective refraction of myopia was increased 0.68±0.49D than wearing Orthokeratology Lens before, but compared with the growth (2. 08 ± 0. 57) D of the control, the effect of myopia control was more obviously. Grade of dry eye was more severely than that of wearing Orthokeratology Lens before, but there was no significant difference between groups A and B. Compared with wearing Orthokeratology Lens before, corneal thickness, anterior chamber depth, corneal endothelial cell number and the intraocular pressure were all no significant differences between the trial and control group.CONCLUSlON: Orthokeratology is a safe and effective method for the correction of myopia, and long-term use of Orthokeratology Lens can effectively control the development of myopia. Controlling of moderate myopia is more effective than that of low myopia.

Objective To explore the relationship between the level of high-sensitivity C-reactive protein (hs-CRP),CRP 1059G/C gene polymorphism and cerebral infarction(CI).Methods The CRP 1059G/C genotype and allele frequencies were assayed by polymerase chain reaction-restricted fragments length polymorphism (PCR-RFLP) in 105 patients with CI and 121 controls.The level of serum hs-CRP was detected by immune-turbidimetry.The relationship between the condition of CI patients,the level of serum hs-CRP and CRP 1059G/C genotype and allele frequencies were anaysed.Results Compared to the control group,the CRP 1059G/G genotype and G allele frequencies in CI group were statistically higher,G/C+C/C genotypes and C allele frequencies were statistically lower(all P

Objective To explore the effect of carotid atherosclerotic plaque ( CAP) on severity and recurrence of patients with cerebral infarction ( CI ) .Methods The prospective cohort study was utilized in this research. Existence and type of CAP were detected by Doppler ultrasound, and patients were divided into plaque group and without plaque group.The patients was evaluated by NIHSS on admission and 7 d, 14 d after admission, and patients were followed up for 1 year.The condition of CI recurrence was be observed.Results According to the Doppler ultrasound, patients were divided into plaque group ( 173 cases, 70.3%) and without plaque group ( 73 cases, 29.7%) .Compared with without plaque group, age, NIHSS score and incidences of hypertension, diabetes, hyperlipidemia, hyperfibrinogenemia were significantly increased (P<0.05 -0.01).In the patients who were conducted follow-up, cerebral infarction recurrence was in 39 cases (24.84%) in plaque group, recurrence time was 10.12 month.The recurrence time was 11.82 month in patient with non-vulnerable plaque, it was 10.62 month in patient with mixed plaque, and it was 9.13 month in patient with vulnerable plaque.Cerebral infarct recurrence was in 7 cases (10.45%) in without plaque group, recurrence time was 11.56 month.The recurrence rate in plaque group was significant increased than that in without plaque, however, the recurrence time for without plaque group was longer than that for plaque group ( all P<0.05 ) .The recurrence rate and recurrence time in patient with vulnerable plaque was significantly earlier than that in patient with non-vulnerable plaque (P=0.034).Conclusion The CAP in patients with acute CI can exacerbate the disease, and increase recurrence rate.It is especially in patients with vulnerable plaque.

Objective To study the expression and the role of interleukin (IL)-23/IL-17 axis in colonic tissue of trinitrobenzene sulphonic acid (TNBS) induced eolitic mice.Methods Mice were divided into four groups:control (n=24),TNBS (n= 24),TNBS 48 hours + mlL-17 antibodies (n=24),TNBS 48 hours + normal rat blood-serum (n= 24).TNBS-induced colitis model was constructed.The mice in control group and TNBS colitis group were sacrificed at 24 hours,48 hours,7th day,respectively.In TNBS 48 hours + mlL-17 antibodies group and TNBS 48 hours + normal rat blood-serum group,a single injection with the polyclonal mlL-17 antibodies or serum were given intraperitoneally at two hours before enema with TNBS,respectively,and the mice were killed at 48 hours after enema with TNBS.The histological score of colon and myeloperoxidase (MPO) activity of colonic tissue were evaluated in each group.IL-23p19 and IL-17 concentrations in colonic tissue were measured by enzyme-linked immunosorbent assay (ELISA).Expression of nuclear factor (NF)-κBp65in colonic tissue was detected by immunohistochemistry method.Expression of IL-23p19,IL-17 and IL-12p35 mRNA in colonic tissue were detected by real-time fluorescent quantitative reverse transcriptase polymerase chain reaction (RT-PCR) with SYBR Green I.Results The protein levels of IL-23p19 in colonic tissue in TNBS colitis groups at 24 hours,48 hours and 7 days were (15.53±3.32),(31.16±4.98) and (14.03±3.56) ng/mg,respectively,and their mRNA level were (4.09±0.34),(3.39±0.46) and (6.54±1.82),respectively.The protein levels of IL-17 were (0.35±0.06),(0.38±0.08),and (0.26±0.05) ng/mg,respectively,and their mRNA level were (4.21±2.61),(2.65±0.91) and (5.63±1.43),respectively.The expression levels of IL-23p19 and IL-17 in colitis model were significantly higher than those in control group and the peak was at 48 hours.Moreover,expression of IL-23p19 and IL-17 and their mRNA were positively correlated to their mRNA levels.In TNBS 48 hours + mIL-17 antibodies group,the expression levels of NF-κBp65,the microscopic scores and MPO (1.86 % ± 0.36 %,0.63 ± 0.52,0.40 ± 0.03 U/g,respectively) were significantly lower than those in TNBS 48 hours group (4.35% ±0.37%,5.13±0.64,2.29±0.40 U/g tissue,respectively).Neutralization of IL-17 was significantly protected against TNBS-induced colonic inflammation and MPO and expression of NF-κB p65.The results indicated that neutralization of IL-17 significantly reduced colonic inflammation and suppressed NF-κBp65 activation.This protection occurred in the presence of equivalent induction of local IL-23 p19 and high levels of IL-12p35 in the polyclonal raiL-17 antibodies-treated mice.Conclusions IL-23/IL-17 axis plays a critical role at the early acute phase of TNBS-induced inflammation.IL-17 may represent a new target for therapeutic intervention for inflammatory bowel disease.

Objective To study the way of blocking the father-child、mother-child transmission of HBV.Methods 387 fathers or mothers who were positive for HBV-DNA were divided into three groups according to the father and mother's HBV-DNA and anti-HBsAg. Then they were randomly divided into three groups,one group were treated by HBIG,the second group were treated by lamivudine,the third group were treated by HBIG and Lamivudine.90 of their children who were positive for HBV-DNA were randimly dinded into three groups,one group were treated by hepatitis B Vaccine,the second group were treated by hepatitis B Vaccine and HBIG,the third group were treated by hepatitis B Vaccine and Gm-CSF. Their serum HBV-DNA were tested by fluorescence quantitative - PCR method.Results After treatment on the fathers or mothers,the degree of HBV-DNA was decreased obviously. There were significant difference between the groups who were treated by HBIG and lamivudine and the group who were treated only by HBIG or lamivudine( P ＜0.05 ). The rate of their newborn with HBV-DNA( + ) were significantly lower then other groups. After treatment on the newborn with HBV-DNA( + ). The degree of HBV-DNA had significant difference between the groups who were treated by both drug and vaccine and the vaccine group(P ＜0.05). Conclusion The fathers or mothers with HBV-DNA( + ) were treated by HBIG、lamivudine before they want a child, and fheir newborn with HBV-DNA( + ) were treated by vaccine、HBIG、Gm-CSF. This was an important way to block the father-child、mother-child transmission of Hepatitis B Virus.
