Objective To introduce laminar shelling decompression technique and to discuss its benefit for decompression of thoracic ossification of ligamentum flavum. Methods 102 patients were diagnosed as thoracic ossification of ligamentum flavum, 63 males and 39 females with an average age of 49.7 years (range, 33 to 71 years). 99 cases suffered with sensation disturbance, 73 cases with constriction on trunk or lower limbs, 77 cases with sphincter dysfunction. The IMSOP Standard Neurological Classification of Spinal Cord Injury was applied for localized the level of thoracic spondylopathy. The JOA lower limb motor function standard and sphincter function standard were used to evaluate the ability of lower limb motion and sphincter function respectively. In the decompression the dorsal cortex of lamina was the first layer to resect, the facet joint surface indicate the depth for removing the second layer, then thinning the ossified tissue by shaving with the motor bur until it was somewhat lucent. Finally decompress the spinal canal by moth eaten manner. Results The mean decompression length was 2.8 lamina(2 to 4 lamina). The mean follow-up duration was 18.9 months (3 to 41 months). Among 99 sensation disturbance 69 totally recovered, 30 relived. 73 cases with the feel of constriction of trunk or lower limbs were completely recovered. Postoperative JOA sphincter function score was 2.632?0.407, comparing with the preoperation score, and the difference was significant (t=15.93, P

3 cm)ultrasonography image was the absent of rotator cuff image(nonvisualization)or discontinuity(local nonvisualization);moderate full thickness cuff tears(size 1-3 cm)ultrasonography image was the hypoechoic zone extending through the entire substance of the cuff;bursa surface partial thickness was small hypoechoic discontinuities of the external surfaces of the cuff;articular surface partial thickness was small hypoechoic discontinuities of the internal surfaces of the cuff.All the ultrasonography examination results were compared with findings at shoulder operation or arthroscopy as a golden standard.12 shoulders were open repaired;16 shoulders were limited open and arthroscope repaired;6 shoulders were contracted under the radio frequency ablation;22 shoulder were taken acrominal plasty under the arthroscope.Results The ultrasonography correctly depicted 30 of 33 rotator cuff tears with sensitivity 90.91%,specificity 91.30%,positive predictive value 93.75%,negative predictive value 87.50%.6 large to extensive tears,11 small and moderate full-thickness tears,5 acrominal partial-thickness tears,11 articular partial-thickness tears.Conclusion The ultrasonography is a highly accurate diagnostic method for detecting full-thickness rotator cuff tears,but is less sensitive in detecting partial-thickness rotator cuff tears.

Objective To investigate the pathological and physiopathological difference between the ruptured” and the “degenerated” typed lumbar disc herniation (RDH and DDH) by measurement of the pressure of the herniated lumbar disc both in the herniated site and in the nucleus pulposus during the surgery, combined with the clinical,light microscopical and immunohistochemical properties. Methods Fifty seven cases of lumbar disc herniation undergone operation in the Tianjin Medical University Hospital were included in this study. The patients were divided into 2 groups. 1) Rupture typed lumbar disc herniation in which the herniated chip of the lumbar disc separated from the parent disc and was squeesed or drew out easily when the superficial posterior longitudenal ligament and anulus fibrosis were opened in the herniated site. 2) Degenerated typed lumber disc herniation in which no herniated chip of the lumber disc escaped; the herniated material can not be taken out unless the disc was resected by the instrument. Before the herniated disc was incised, the intervertebral disc pressure was measured using GENERAA710 multifunctional monitor. Both the light microscopical and the immunohistochemical difference between the RDH and the DDH was studied. Results 1) In the herniated site, the pressure in the RDH is higher than that in the DDH(P0.05). 3) In the RDH, the pressure in the herniated site is higher than that in the nucleus pulposus (P0.05). 5) The“lumbar pain score”and the pressure have obviously relationship in all of 35 patients(r=0.539,P

Background:Small bowel Crohn's disease (CD) is a chronic nonspecific inflammatory disease with unknown etiology.There is no clear criteria for assessing the progression of CD, and the endoscopic index for assessing disease activity in CD patients is limited to a single parameter.Aims:To investigate the clinical value of endoscopic index in evaluating disease activity in patients with CD and the correlation between different parameters.Methods:Sixty cases of CD patients form Jan.2008 to Dec.2012 at Affiliated Hospital of Yanan Uuiversity were collected, 60 healthy adults were served as control group.CECDAI score, CDAI score and Lewis score were used to evaluate disease activity in patients with CD, and their relationship with CRP and ESR were analyzed.Results:Levels of CRP and ESR were significantly increased in CD patients than in controls (P<0.05).CDAI score and Lewis score were statistically different in different CECDAI score groups (F=5.53, P<0.05;F=22.64, P<0.05).CECDAI score was statistically different in different CDAI score groups (F=3.55, P<0.05), and was statistically different in different Lewis score groups (F=4.26, P<0.05).CECDAI score was correlated with CDAI score, Lewis score, CRP, ESR (P<0.05);CDAI score was correlated with CRP, ESR (P<0.05) and not correlated with Lewis score (P>0.05);Lewis score was not correlated with CRP, ESR (P>0.05) in CD patients.Conclusions:CECDAI score, CDAI score, Lewis score, CRP, ESR can reflect disease activity of CD, and can be used together to assess disease activity of CD patients.

Objective To investigate the in vivo effects of glutamine(Gln) on inflammatory cytokine release in murine peritoneal macrophages during sepsis. Methods Sixty Kunming mice were randomly divided into sham-operation group(Sham group,n=20),operation control group(Con group,n=20) and Gln-treatment group(Gln group,n=20).Sepsis was induced by cecal ligation and puncture in Gln group and Con group,and Gln(0.75 g/kg) or saline was immediately administered via single tail vein injection.Serum was collected and macrophages were harvested from peritoneal lavage at 6 h in these three groups.Intracellular and serum cytokines of tumor necrosis factor-?(TNF-?),interleukin(IL)-6 and IL-10 were detected by ELISA.The expression of TNF-? mRNA in macrophages was analyzed by RT-PCR,and the expression of heat shock protein(HSP) 72 in macrophages was evaluated by Western blotting. Results Gln group demonstrated significantly lower intracellular TNF-? and IL-6 levels than Con group(P0.05).The serum TNF-? level was significantly lower in Gln group than in Con group(P

ObjectiveTo observe and analyze the synapses developing process of newly generated connections of autologus activated Schwann cells (AASCs) in combination with fetal spinal cord cell suspension(FSCS) in the surrounding area of the spinal cord injury site.MethodsA total of 42 Wistar rats underwent unilateral ligation of the saphenous nerve.The portion of nerve tissues distal to the ligation site were harvested 1 week after operation.AASCs were isolated,cultured and purified.Spinal cord injury model produced in 42 Wistar rats on T7 by modified Allen impact method.Three days after injury,20 μl FSCS with a density of 1×105/μl prepared from pregnant rats (El4) in combination with AASCs were injected into the epicenter of the traumatized cavity.Animals were sacrificed at 2,4,6,8,10,12 weeks post transplantation.Light and electronmicroscopic studies as well as immunohistochemical assay were carried out to evaluate the graft survival,its differentation and integration with the host.ResultsIn the transplantation area,AASCs showed good growth and differentiation,and glial scarring surrounding the lesions was less.The neuroblast stretched out the terminal endings 4 weeks after implantation,followed by the presenting of the pre- and post-synaptic membrane.Eight weeks post transplantation,the dense or developed projections were observed in the pre- and post-synaptic membrane,the high electron dense substance full filled the synaptic cleft.All the spherical cleat vesicles,granular vesicles,elliptical vesicles and flattened-f type vesicles were discovered under the electron microscope.Ten weeks after injury,the axosomatic,dendrosomatic,dendro-dendritic,axoaxonic,and dendro-axonic synapses coexisted.Light microscopy showed that the graft cell grew gradually.Immunohistochemical assay showed that NF,5-HT,CGRP and GFAP positive fibers were in the graft.Synapses,glia fibers and blood brain barrier integrated each other.Conclusion1) The transplanted FSCS combined with AASCs can develop mature synapses with miscellaneous synaptic vesicles in the acute injured spinal cord.2) Co-existing indicate the possibility of synaptic connection between FSCS and host.

Objective To assess the relationship between serum uric acid (SUA)and metabolic syndrome and coronary artery disease(CAD).Methods 232 untreated subjects with essential hypertension were divided into two groups(CAD and no CAD)by coronary angiography.All subjects were free of myocardial infarction,cardiomyopathy,valvular disease, atrial fibrillation,aortic dissection,and renal disease.Results Compared to no CAD group,age,diabetes,triglycerides and SUA in CAD group were higher.There was a significant association between SUA and the severity of CAD (P=0. 015).However,after adjustment for concomitant risk factors of cardiovascular disease,SUA was not an independent risk factor of CAD(P=0.151).In sex-specific analysis,there was a trend of SUA to be an independent risk factor of CAD in women(P=0.062),but it was no statistic significance.The highest quartile level of $UA tended to be associated with increased risk for CAD,but it was not statistically significant either(OR=2.52,P=0.075).SUA was closely associated with metabolic syndrome and diabetes in woman.Conclusion In untreated patients with essential hyperteusion,SUA was associated with metabolic syndrome and the severity of CAD,but it is not an independent risk factor of CAD,the raised SUA may be only a marker of insulin resistance.

Objective　To study the cochlea microvasculature permeability changes of the inner ear in guinea pigs, so as to clarify the possible role of the cochlea microvasculature permeability changes in the ischemic injury of inner ears. Methods　Modified method of Evans blue fluorescence was used to observe the changes of permeability of the cochlea microvasculature in the animal model of cochlea microcirculatory disorders which was caused by photochemical reaction. CAPN1 threshold was recorded by using Madsen 2 250 to study the hearing loss. Results　The amounts of Evens blue crossing the cochlea microvasculature were (1.709±0.769) and (2.849 ±0.653) μg/per animal 2 and 4 h after the development of cochlea microcirculatory disorder in guinea pigs, respectively (P<0.01); and their hearing loss were （24.44 ±7.27） and （38.33±7.91）dBpeSPL in 2 and 4 h, respectively (P<0.01)． Conclusion　The permeability of the cochlea microvasculature increases along with the duration of cochlea microcirculatory disorder occur and the increase of cochlea microvasculature permeability might be one of the important mechanisms inducing cochlear ischemic lesions.

Objective To investigate the relationship between personal disposable income and female depression,and to examine the moderating roles of personality in this link.Methods The demographic questionnaire,self-rating depression scale (SDS) and eysenck's personality questionnaire short scale (EPQ-RSC) were used to survey 139 cases of married female patients with depression.Results Personal disposable income could be used to significantly and negatively predict female depression(β=-0.669,P＜0.01).The interaction between personal disposable income and introversion-extroversion,personal disposable income and neuroticism was significant (β=0.142,P＜0.05.β=-0.232,P＜0.01).In the groups of higher and lower scores on the introversion-extroversion dimension,personal disposable income could be used to significantly predict female depression(β=-0.397,P ＜0.05.β=-0.452,P＜0.05).In the group of higher scores on the neuroticism dimension,personal disposable income could be used to significantly predict female depression(β=-0.553,P＜0.01),but not in the group of lower scores(β=-0.349,P＞0.05).Conclusion Personal disposable income has significantly negative prediction effect on female depression,and introversion-extroversion and neuroticism have significant moderating effects on the relationship between personal disposable income and female depression.
