Objective To explore the changes of thyroid hormone and TNF-α in severe patients which occurring under critical illness and to explore the interrelation of these endocrine factors in order to direct clinical therapy. Methods Serum thyroid hormone and TNF-αin 102 severe patients and 80 healthy volunteers were detected by radioimmunoassay and enzymoimmunoassay. The results were analyzed and compared with normal subjects,groups of different prognosis,MODS group and no MODS group. Results TT3,FT4,FT3 levels in severe pa-tients were lower than that in normal subjects(P <0. 01),By contrast,TNF-α level were significantly higher than that of control group (P<0. 01). As the situation became worse,the above changes were more obvious in severe patients as compared with normal subjects. For TT3 and TNF-α level,the differences in the early stages of the disease (3 ~7rd) in the survival group and death group were significant (P<0. 05). Compared with non-MODS group,TT3,FT4,FT3 and TNF-α changed significantly in MODS group(P<0. 05). Conclusion TNF-α and thyroid hormone levels play important roles in the severe patients. The changes of TNF-αand thyroid hormone levels can be used for severe patients prediction and treatment.

Impotence is one of the more common and serious symptom type of male sexual disturbance.It demonstrates by domestic sampling investigation that about more than 10% of male adult have impotence,and the incidence of impotence goes higher with the growing of age.Warming and invigorating kidney-yang has been the main therapy method for treating impotence.Through years of clinic practices,the treatment for impotence from liver has achieved satisfied effects.

Objective To describe the clinical and imaging manifestations of patients with synovitis acne pustulosis hyperostosis osteomyelitis (SAPHO) syndrome,and to analyze the diagnostic importance of different clinical and imaging manifestations for SAPHO syndrome. Methods Seventeen patients (7 males and 10 females) with SAPHO syndrome were recruited in this study.Age ranged from 36 to 67 years with a mean age of (48 ± 8) years. All patients fulfilled the diagnostic criteria of Benhamou. Serum HLA B27 antigen records were reviewed for all patients. Imaging data of the abnormal bone sites were collected by conventional radiograph in all patients,CT in 13 patients as well as MR in 3 patients.Average time to take for a definite diagnosis of the syndrome was 3.7 years (ranged from O.5 to 13 years).Results Serum HLA B27 antigen was positive in all patients. Both skin and bone abnornalities were found in all patients.Ten patients had skin palmoplantar pustulosis and two patients had acne. Involving sites of bone and joints include sacroiliac joints,anterior chest and limbs.Sacroiliac joints were asymmetrically involved with imaging features in all patients.Eight patients exhibited anterior chest wall involvement. Five patients had osteomyelitis at limbs. For all images of 17 patients,CT was superior to conventional radiography in detecting abnormal changes of bone erosion and soft tissue swelling.MR imaging was able to depict edema changes that was not detectable by CT and radiography.Conclusion SAPHO syndrome is a rare disease,but for patients with skin and bone-joint abnormalities,especially with skin palmoplantar pustulosis,acne as well as with imaging features at the sacroiliac joint and anterior chest wall,SAPHO syndrome should be taken into a diagnostic consideration.

Objective To assess the value of MRS in evaluating vertebral bone marrow. Methods A total of 152 female volunteers (mean age 58±14 years, ranged 30～80 years) were recruited in this study. All subjects underwent vertebral MRS examination after routine MRI examination (sagittal T_2WI, T_1WI and axial T_2WI). Single voxel (SV) was chosen for the 1H MRS acquisition at L_2～L_4 vertebral body with PRESS sequence. MRS parameters were measured by SAGE 7.0 software. Results The fat fraction (FF%) of vertebra ascend with aging;the water line width (LW) decrease with aging and there was not obvious tendency with lipid LW. Conclusion Vertebral MRS can be considered as a noninvasive examination added to routine spine MRI to demonstrate the changes of vertebral bone marrow.

Objective To study the expression of HIF-1α and survivin in gastric cancer,and to study their role in tumor angiogenesis,invasion and metastasis.Methods Immunohistochemieal technique was used to detect the expression of HIF-1α and survivin in 54 cases of gastric cancer.Results The expression rate of HIF-lα in gastric cancer (74.1%) was higher than that in normal gastric tissue (O),The expression of HIF-1α in gastric cancer was associated with TNM staging,invasive depth and lymph-node metastasis (P<0.05),The expression of survivin in gastric cancers was high (72.2%),and increased with invasive depth (P<0.01),clinical stages (P<0.01) and lymphatic metastasis (P<0.05).There was a positive correlation between expression of HIF-1α and Survivin (r:0.31,P<0.05).Conclusion HIF-1α and Survivin could be factors in the judgement of the degree of malignancy of gastric cancer and prediction of its prognosis.

Objective To analyze the cause of missing diagnosis for vertebral fracture on lateral chest radiography. Methods Lateral chest radiographies of 1638 hospitalized patients (871 males and 767 females) were retrospectively reviewed for identifying vertebral fractures. Their ages ranged from 50 to 91 years with the mean of 63.5 years. Complains and application for chest radiography in all patients were not related to osteoporosis and vertebral fracture. Vertebral fracture and fracture severity were evaluated using Genant's semiquantitative visual method, taking approximately a 20%-25% vertebral height reduction as mild grade,26%-40% as moderate grade and 41% or greater as severe grade. Evaluation results of the vertebral fracture, original X-ray reports, as well as medical records were compared for further analysis. Results Eighty-four in 1638 patients showed vertebral fractures on the lateral chest radiographies. Of them,vertebral fractures were reported in 30 cases and 54 patients were not reported on their original X-ray reports. There were 63 vertebral fractures in 54 un-reported patients, most of which were single fracture (75% or 47/63). Grade Ⅰ fracture accounted for 54% (34/63), Grade Ⅱ fracture 33% (21/63), while 13% presented grade Ⅲ fracture (8/63). In all 84 patients with vertebral fractures, only 5 cases (6%)underwent dual energy X-ray absorptiometry (DXA) measurement, 5 cases ( 6% ) were recorded to have vertebral fractures on the medical papers, as well as 15 cases ( 18% ) were prescribed drugs related to the osteoporosis when discharged from hospital All drugs prescribed for the 15 patients were limited only to calcium. Conclusions More attention should be paid to osteoporosis by doctors including radiologists.Vertebral fracture on lateral chest radiography should be completely diagnosed, which is helpful for both prevention and treatment.

Objective To analyze MRI appearance after augmentation mammoplasty,and to assess the clinical value.Methods Sixty-three cases with augmentation mammoplasty were imaged by MR scanner.MR imaging features of silicone implant and injected implant were analyzed respectively.Results(80 breasts) in 40 patients were with polyacrylamide hydrogel injection.In 50 breasts,the implants were shown as irregular gel in mammary gland,pectoralis muscle,and subcutaneous tissue.Auto-fat injection in both side of breast was performed in 7 cases.Among them,fibrofatty mass was detected in 12 breasts,fat-fluid interface was seen in 6 breasts,and fat in pectoralis major was revealed in 6 breasts.Silicone implant in both side of breast was performed in 16 cases.2 breasts in 2 case were detected as saline-filled implants with intracapsular rupture.14 cases were with silicone gel-filled implants,among them,4 breasts were found to have extracapsular rupture and 10 breasts intracapsular rupture.Conclusion MRI is a perfect method in accessing the patients with augmentation mammoplasty.

Objective In our previous study, we had generated various zebrafish mutant lines with tissue?specific GFP expression by Tol2 transposon?mediated insertional mutagenesis. Among these mutants,the Tol2:20141221t line ex?presses GFP in nervous system, while the position within zebrafish genome where transposon inserted has not yet been iden?tified. The aim of this study was to identify and analyze this genetically modified mutant. Methods The transgenic inser?tion loci in the genome of Tol2:20141221t line was identified byTAIL?PCR and the spatial and temporal expression profile of the affected gene was examined by in situ hybridization. Homozygous mutant of Tol2:20141221t was generated for explo?ring related developmental defects. Results Tol2 transposon was inserted into the 8th intron region of sat1.a gene, and in?duced premature transcription termination. The maternal and zygotic mutants of Tol2:20141221t was generated, while with?out apparent developmental defects. Conclusions We have generated and identified the zebrafishsat1.a mutant mediated by Tol2 transposon. This gene insertion mutant exhibits no obvious developmental abnormalities, but may serve as a power?ful tool to study the development of nervous system.
