Objective To explore the adjustment and posttraumatic growth of people with spinal cord injury from the community. Meth-ods From January 2013 to May 2015, Semi-structured in-depth interviews were used to interview 12 participants with spinal cord injury from Sunshine Rehibilation Center. Interviews were recorded on audio-tape with participants' permission and then transcribed verbatim. The transcribed interviews were analyzed according to interpretative phenomenological analysis. Results 3 superordinate themes emerged includ-ing struggling in despair, disentangling from the shadow of disability and continuing with life as normal, facing challenge and achieving pos-itive growth. Conclusion It is necessary to explore the process of adjustment and posttraumatic growth of people with spinal cord injury, which contribute to understand their psychological experience, psychological feature, and coping strategies, promote their physical and psy-chological recovery, and provide theory and practice guidance for family and society re-integration.

BACKGROUND:Demineralized bone matrix as bone tissue engineering biological scaffold material is more researched currently, which has osteoinductive and osteoconductive.
OBTECTIVE:To summarize the development of demineralized bone matrix as bone tissue engineering scaffold material and to prospect its trend.
METHODS:The relative literatures addressing demineralized bone matrix as bone tissue engineering scaffold material published between January 1965 and May 2013 in PubMed database, Chinese Biomedical Database, Wanfang Database and FMJS database were searched by the first author. The key words were“demineralized bone matrix, scaffold material, growth factor, cells, drugs”in English and Chinese. According to the inclusion criteria, repetitive researches were excluded, and final y 34 articles were included.
RESULTS AND CONCLUSION:Scaffold material is the key composition of tissue engineered bone, and only demineralized bone matrix has both osteoinductive and osteoconductive properties which cannot only provide space for bone repair, but also can be combined with bioactive factors, living cells, antibiotics in vitro to construct bone graft thereby promoting healing of bone defects. However, this technique is also facing some problems to be solved such as the ratio of demineralized bone matrix and various substances, disinfection, preservation of osteogenetic activity and antigenicity elimination. Sufficiently understanding demineralized bone matrix as bone tissue engineering scaffold can provide a theoretical basis for its clinical service.

Objective To develop a quality of life scale suitable for aphasic Chinese stroke patients by translating and evaluating the psychometric properties of the original 39-generic version of the Stroke and Aphasia Quality of Life scale (SAQOL-39g).Methods The SAQOL-39g was translated into Chinese and edited.The well edited and translated self-rated and non-self-rated scales were used to test 86 aphasia patients and their caretakers to evaluate the feasibility,internal consistency,test-retest reliability,content validity,and construct validity of the scale.Results The feasibility of the Chinese version of the SAQOL-39g scale was sufficient,with 97％ of the ques tionnaires completed.The average time taken to complete the self-report version was (21.4±4.37) minutes,with (13.25±5.61) minutes needed for the proxy version.The Cronbach's alpha values for the overall survey ranged from 0.879 to 0.950 and for the subdomains from 0.863 to 0943 for both forms,suggesting satisfactory internal reliability.The test-retest coefficients for the two forms ranged from 0.804 to 0.974 and from 0.861 to 0.987.A total of 3 common factors were extracted using factor analysis,and the cumulative contribution rate was 59.7％.The consistency between the self-reports and the proxy-reports was good.Conclusion The Chinese version of the SAQOL-39g scale demonstrates good feasibility,reliability and validity,and good consistency between the self-reported and proxy-reported versions.It seems suitable for assessing the quality of life of Chinese stroke patients with aphasia.

Objective To determine the correlation between the expression of interleukin 8(IL-8) and lymph node metastases in earlier uterine squamous cervical cancer and to study the mechanism of metastases of earlier squamous cervical cancer. Methods IL-8 mRNA expression was examined with reverse transcription polymerase chain reaction(RT-PCR) and tissue microarray to determine the expression of IL-8 protein. The matrix metalloproteinase 9( MMP-9) protein and microvessel density (MVD) in earlier squamous cervical cancer were decided respectively by antibody against IL-8, MMP-9 and CD-34 associated antigen and Immunohistochemical analysis. Results The cervical cancer with lymph node metastases express IL-8, MMP-9 and MVD at significantly higher level than negtive metastatic lymph node(P =0.00,0.00,0.02). Otherwise, the express of IL-8 correlated strongly and positively with MVD of cervical cancer(r =0.251,P

Background and purpose:MMMT is known as a rare malignancy in gynecological tumor. Because of its difficulty in diagnosis and treatment, the prognosis is extremely poor. This study was to discuss the clinicopathologic feature and PRA,PRB expressions of uterine MMMT. Methods:We analysed clinicopathologic data and the expressions of PRA,PRB by immunohistochemical staining on 17 cases of uterine MMMT, and 11 patients were followed up. Results:①The patients usually presented with abnormal vaginal bleeding with no specifi city clinically. ②The morphological changes were various and complicated, including epithelial and mesenchymal components and a variety of inter-permeated and transitional tissue elements.③The positive rate of PRA in stageⅠ and stageⅡ were 66.7% and 40%, and PRB in stage Ⅰ and stageⅡwere 55.6% and 20%, respectively. ④The mean survival time in stageⅠ,Ⅱ and Ⅲ were 43.8 months (32-59), 34.25 months (19~41) and 5 months, respectively. Conclusion:The diagnosis of uterine MMMT was mainly based on tissue morphology; the development of uterine MMMT might be related with the loss of PRA and PRB ; the clinical stage and the expression of PRA and PRB might be the prognostic factors for uterine MMMT.

Objective To discuss the imaging technology and characteristic of perfusion-weighted imaging in rabbit models of hepatic VX2 tumors. Methods Twenty-eight New Zealand rabbits were implanted in liver with VX2 tumor by tissue block. After routine scans were performed on 1.5 T MR scanner, 28 New Zealand white rabbits with VX2 carcinoma were divided randomly into treatment group and control group. Treatment group was divided randomly into group A, group B and group C, 7 animals per group. Perfusion weighted imaging(PWI) was performed in day 14, 25 and 35, respectively, after tumor implantation in all animals. Select the regions of interest (ROI) of the VX2 tumor center, tumor border and pars-tumor parenchyma. Maximal signal reduction slope ( SRSmax ) of the signal intensity versus time curves were created as quantitative variable, and the parameters were calculated and compared in all groups. Results Maximal signal reduction slope ( SRSmax ) of the signal intensity versus time curves were studied in 4 groups, 23 VX2 rabbits,7,5 and 6 in group A , B and C, respectively. The SRSmax of tumor center were ( 12. 6 ± 3.4), ( 9. 8 ± 2. 6 ) and ( 1.0 ± 0. 4 ), the difference was significant ( F = 10. 855, P < 0. 05 ). The SRSmax of tumor border were(48. 3 ± 2.4), (46. 2 ± 1.5 ) and (43. 6 ± 1.8 ) ( P > 0. 05 ). The SRSmax of para-tumor parenchyma were ( 14.4 ± 3.0 ), ( 12. 2 ± 1. 4 ) and ( 14. 8 ± 5.0 ) ( P > 0. 05 ). The difference was significant in different ROI in treatment groups( F value was 7. 435,8. 625 and 12. 595, respectively, P < 0. 05 ). Conclusion PWI can be used in evaluating the liver tumor angiogenesis and angio-degeneration with the treatment of HIFU. It will be possible for qualitative analysis of rabbit models of hepatic VX2 tumors by different treatments.
