The surface-enhanced Raman spectra of bilirubin and biliverdin were obtained.By the bands analysis of the spectra,the orientation of bilirubin and biliverdin on the surface of silver colloid was discussed.In such case,the bilirubin was adsorbed on the silver colloid particle with the two planar pyrromethenone groups intercalated into the globe silver colloid particle,however,the biliverdin might lie flat on the surface of silver colloid with syn-synsyn conformation.

Objective To discuss the femoral neck anteversion(FNA) of developmental dislocation of the hip(DDH) and guide operation with visual and digitalized picture in the dimensional(3D) CT.Methods Ninety children with unilateral DDH were selected,and they were analyzed using 3D CT.Children whose FNA exceed 45 degree received the subtrochanter osteotomy with images from different direction,FNA of hip was measured respectively before and after operation and was measured in normal and abnormal hips respectively,FNA of hip received respectively statistical treatment.Ninety patients (90 hips) were followed up ranging from 3 months to 2 years with the mean of 13 months.Results In the group younger than 18 months,the FNA whose in normal hips was(19.40?3.512)degree,the FNA while(68.45?12.272)degree in dysplasia hips respectively,the FNA measured after operation was (20.45?2.940) degree;in the group elder than 6 years,there were significantly statistical differences,the FNA in normal hips was(19.44?3.561)degree,in dysplasia hips respectively was(73.49?12.678)degree,while the FNA measured after operation was(18.28?1.931)degree.Clinical assessment was performed according to Mckay′s classification.The results showed that the overall excellent or good rate was 95.6%.Conclusions 3D CT method is a new accurate and convenient and reduplicative method for measuring FNA.It will be more helpful for related operations when 3D images are considered.

Objective To study the inter-rater reliability of Wisconsin Gait Scale (WGS) and Gait Abnormality Rating Scale (GARS) in patients with stroke. Methods 20 hemiplegic patients were required to walk on their comfortable speed and videotaped from frontal, backward and lateral. The video recordings were scored with WGS and GARS by 2 experienced physical therapists. Intraclass correlation coefficient (ICC) was calculated for the scores in each category and the total score. Results ICC for the WGS were 0.372~1, and were 0~0.875 for the GARS. Conclusion WGS is more appropriater to assess the gait of hemiplegic stroke patients than GARS.

ObjectiveTo study the speciality of hemodynamics in middle cerebral artery(MCA) by means of transcranial color Doppler ultrasound(TCCD) at different tilting angles in patients with cervical and thoracic spinal cord injury.Methods48 patients with spinal cord injury were involved. The velocity of peak systolic(PSV), end diastolic(EDV) and mean velocity(MV) of MCA on the tiltable at 0°,30°,60°,80° were measured.ResultsThere was no significant difference in PSV between 0°and 30°(P>0.05), while EDV and MV showed very significant (P<0.01)from 0°to 30°,60°and 80° position. From 0°to 60°,80°,there were differences not only at EDV and MV, but also PSV(P<0.01).ConclusionThe velocities of MCA were changed at different tilting angles in the patients with spinal cord injury.

ObjectiveTo study the features of lower limb vein thrombus patients after spinal cord injury and the effects of thrombolysis therapy.MethodsWe practiced ultrasonography on 207 patients with lower limb swelling after spinal cord injury. ResultsAmong the 207 patients, 66 had thrombus, the positive rate was 31%: acute thrombus 58 cases, subacute thrombus 1 cases and chronic thrombus 7 cases. Conclusions Ultrasonography provides an important basis for the qualitative diagnoses of lower limb vein thrombus. It has certain clinical guiding effects in choosing methods of treatment.

This study was aimed to investigate the abnormal expression of microRNA-124 (miR-124) in bone marrow cells of patients with leukemia or myelodysplastic syndrome (MDS) and its significance. The relative expression levels of miR-124 in bone marrow mononuclear cells from 33 patients with newly diagnosed leukemia or MDS, and 10 normal donors (as controls) were detected by stem-loop fluorescence real-time quantitative RT-PCR. The methylation levels of miR-124 promoter were detected by quantitative methylation specific PCR in partial MDS samples. The results indicated that as compared with normal control, lower levels of miR-124 (≤ 1/3) were found in 2/18 of leukemia patients and in 5/15 of MDS patients (among them ≤ 1/4 in 3/15 MDS patients). No statistically significance difference was observed between leukemia patients and normal controls (P = 0.725). However the difference was statistically significant between MDS group and control group (P = 0.031). Furthermore, an elevated methylation level of miR-124 promoter region in some of MDS patients (7/11) was detected by using quantitative methylation-specific PCR. The expression level of miR-124 was related with methylation level of promoter region (R(2) = 0.339, P = 0.018). It is concluded that the expression of miR-124 in partial MDS patients is inhibited, which may be associated with the abnormal methylation of its promoter.

Objective To evaluate the efficacy and safety of ESHAP regimen,as a salvage regimen, in treating patients with relapsed or refractory aggressive NHL.Methods 38 patients with relapsed or refrac- tory aggressive NHL were selected to be treated by ESHAP regimen.Results The 38 patients received ES- HAP regimen with a range of 2～6 cycles. The total RR was 55.3 % with complete response(CR)rate of 26.3 %.The major toxicity was myelosuppression with infection,which was tolerable.Conclusion ESHAP regimen is one of safe and effective salvage regimens for the patients with relapsed or refractory aggressive NHL.

Objective To evaluate the clinical significance of the diameter of the esophageal hiatus on multislice spiral CT(MSCT)and to present the MSCT manifestations of esophageal hiatus hernia (EHH).Methods(1)The distance between diaphragmatic crura(DDC),which indicated the diameter of esophageal hiatus,was measured in 140 normal adult patients on their thoracic and/or abdomenal CT images.(2)The DDC of 56 patients with EHH diagnosed by barium examination was measured on MSCT, and the MSCT findings were analyzed retrospectively.Results(1)The DDC of 140 normal adult cases were(13.44?4.41)mm on average and increased with age.The mean DDCs of patients under the age of 59 year-old(80 cases)and over 60-year-old(60 cases)were 11.03?2.10 mm and 16.67?4.64 mm respective]y,there was a significant difference(t=8.762,P
