BACKGROUND:Conservative treatment is mostly invalid in treatment of severe degenerative lumbar scoliosis-induced low back pain, so surgical intervention is general y required. Repair methods are decompression, rigid fixation, and selective interbody fusion for the“responsible vertebra”to re-establish normal lumbar curvature, spinal balance and good stability. OBJECTIVE:To investigate clinical curative effect of local decompression and selective interbody fusion with pedicle screw fixation technique for the treatment of degenerative lumbar scoliosis. METHODS:Data of 57 cases of degenerative lumbar scoliosis from Armed Police Corps Hospital of Hunan Province from January 2011 to January 2014 were retrospectively analyzed. According to clinical characteristics of the patients, selective fusion, local decompression and pedicle screw fixation were used for repair. The imaging analysis and Suk criteria were used to evaluate fixation, decompression and bone fusion. Japanese Orthopaedic Association scores were utilized to assess therapeutic effect. RESULTS AND CONCLUSION:(1) Operation time was 157-255 minutes, averagely 176 minutes. Amount of bleeding was 480-1 700 mL, averagely 835 mL. Postoperative drainage volume was 140-210 mL, averagely 155 mL. (2) 57 patients were fol owed up for 12-38 months. Postoperative X-ray revealed that Cobb’s angle was (3.8±2.1)° on the coronal plane after treatment, and the correction rate of lordosis was 54%. The sagittal Cobb’s angle was (6.3±10.5)°, and the correction rate of lordosis was 35%. According to Suk standard, the fusion rate of vertebra was 95%. According to low back pain score system recommended by Japanese Orthopaedic Association scores, the effective rate was 91%at the end of fol ow-up. (3) There were 2 cases of cerebrospinal fluid leakage, 1 case of nerve injury, and 1 case of pedicle screw failure, no infection, no blood vessel injury. (4) These findings suggest that according to imaging data and self clinical features, local decompression and selective interbody fusion with pedicle screw fixation technique for the treatment of degenerative lumbar scoliosis can rebuild and stabilize degenerative lumbar scoliosis in the coronal and sagittal planes to different degrees, with satisfactory clinical curative effect.

Results In pretreat_ment group, there were 24 Hp positive cases and 38 negative ones according to the golden standard, 27 positive and 35 negative according to one-step HpSA assay, and the sensitivity and specificity was 100% and 92% respectively; In post-treatment group, 15 positive and 27 negative according to the golden standard, 19 positive and 23 negative according to one-step HpSA assay, and the sensitivity and specificity 93%and 81% respectively; the total sensitivity and specificity was 97% and 88% respectively. Conclusions HpSA rapid one-step test has good sensitivity and specificity in diagnosis of Hp infection and judgment of Hp eradication.

Background Peripheral refraction of retina brings about influence on myopia development,and different corrective methods will play different roles on the peripheral refraction.Objective This study was to measure the peripheral refraction with progressive addition lenses (PALs) and single-vision spectacle lenses (SVLs) corrected in adolescent myopic eyes and to investigate the difference between them.Methods This was a selfcontrolled cross-sectional study.Forty corrected myopic eyes with PALs were recruited for the study.Twenty-three male and seventeen female subjects aged 10-15 years (mean 12.54 years±1.45 years) enrolled in this study.The refractive errors of the subjects ranged form-1.50 D to-6.00 D (mean-3.74 D±1.09 D) and the astigmatism was less than-1.50 D with the corrected visual acuity at least 20/25.1％ Tropicamide eye drops was topically administered for the cycloplegia and then Grand Seiko WAM-5500 Auto-refractor was used to measure the peripheral refraction.The measured points were determined follows as:fovea (0°),peripheral temporal (T30°,T20°,T10°) and nasal (N30°,N20°,N10°) visual fields from the right eyes.The mean of the six measuring points for each position was calculated.Peripheral refraction was measured from each subject under the wearing of PALs or SVLs (randomly in succession),and the statistic analyse perimeters included M value,relative peripheral refractive error (RPRE),J45,J180.Written informed consent was obtained from each subject before examination.Results The corrected visual acuity was 4.98 ± 0.65 and 4.97 ± 0.53 under the PALs and SVLs conditions respectively,showing in significant difference between them (t =0.222,P =0.639).Hypermetropic shift in peripheral M value and RPRE value were found with the increase of visual angle field,in contrast,the peripheral J180 showed a myopic shift,and significant difference was found among the six peripheral points with all of the above three perimeters (P＜0.05).Negative J45 values in the temporal visual filed and positive J45 values in the nasal filed showed less shift.Some peripheral angles of the peripheral refractions in M value,RPRE value,J180,J45 showed significantly difference from the fovea refraction(P＜0.05).Compared with SVLs correction,PALs induced relatively myopic shifts in M value and RPRE value in all of the peripheral angle fields,showing significant differences(P＜0.05).Conclusions PALs causes relatively myopic shift at the peripheral retina in adolescent myopic eyes in comparison with SVLs,and the important parameters are M value and RPRE value.The effect of PALs on controlling the onset and progression of myopia may be interpreted by peripheral refraction.

Human bocavirus (HBoV) 1-4 have been detected both in respiratory and stool samples since the first HBoV was discovered in 2005. HBoV-1 is mostly associated with respiratory infection, while HBoV 2-4 are usually associated with intestinal tract infection. A variety of signs and symptoms have been described in patients with HBoV infection, including cough, wheezing, pneumonia, and diarrhea, but the research on pathogenic mechanism of HBoV is limited because HBoV cannot be cultured in vitro due to the lack of appropriate host cells. Three-dimensional epithelial cell culture, reverse genetics, and viral metagenomics are identified as novel tools that may promote the research on pathogenic mechanism of HBoV and the discovery of new viruses. This review summaries currently available diagnostic approaches such as electron microscopy, cell culture, PCR, and immunoassay in order to provide a method reference for indepth research on HBoV.

Objective To explore the expression of matrix metalloproteinase-3 (MMP-3) and matrix metalloproteinase-10 (MMP-10) in normal endometrium, atypical hyperplasia and endometrial adenocarcinoma. We aimed to study the relationship of MMP-3 and MMP-10 expressions with infiltration depth, histologic grade and clinical phase in order to explore the role of MMP-3 and MMP-10 in the occurrence, infiltration and metastasis of endometrial adenocarcinoma. Methods The expressions of MMP-3 and MMP-10 were measured by immunohistochemistry in 12 cases of normal endometrium, 12 cases of atypical hyperplasia and 42 cases of endometrial adenocarcinoma. Results The expression of MMP-3 was 73.8% (31/42), 25.0% (3/12) and 8.3% (1/12) in endometrial adenocarcinoma, atypical hyperplasia and normal endometrium, respectively, whereas the expression of MMP-10 was 76.2% (32/42), 33.3% (4/12) and 0(0/12), respectively. Both MMP-3 and MMP-10 expressions exhibited a pattern of decreased intensity in endometrial carcinoma, atypical hyperplasia and normal endometrium. Furthermore, the statistical analysis showed that the expression of both proteins was significantly greater in endometrial carcinoma than in atypical hyperplasia and normal tissue (P<0.01). Expressions of MMP-3 and MMP-10 had a significant correlation with such clinical parameters as histologic grade, depth of myometrial infiltration and clinical stage (P<0.01). Conclusion MMP-3 and MMP-10 can be used as tumor markers of endometrial carcinoma, and the combined detection of them can increase the detection rate of endometrial carcinoma.
