BACKGROUND:None of the current treatment strategies has been focused on relieving or reversing the disk degeneration process after degenerative disc diseases. In recent years, more and more scientists try to treat degenerative disc diseases using stem cel therapy. OBJECTIVE:To explore the research status and prospects of stem cel therapy for degenerative disc diseases. METHODS: A computer-based online search of PubMed database between January 2004 and December 2014was performed to search related articles with the key words of “stem cel, intervertebral disk” in English. Literatures related to stem cel therapy for degenerative disc diseases were selected; in the same field, the articles published lately in authoritative journals were preferred. RESULTS AND CONCLUSION: A total of 342 articles were primarily selected, and 43 articles were involved in result analysis according to inclusion criteria. Stem cel therapy is a newly treatment for degenerative disc diseases. Cels appropriate for stem cel therapy include embryonic stem cels, induced pluripotent stem cels, mesenchymal stem cels, human umbilical cord mesenchymal stem cels and chondrocytes or nucleus pulposus cels. Although cel leakage, intervertebral disc infection and tumorigenesis are the main chalenges, stem cel therapy for degenerative disc diseases is promising in the future.

BACKGROUND:At present, the clinical treatment of lumbar disc degeneration mainly includes conservative treatment, traditional surgery and minimal y invasive surgery. The therapeutic purpose is to relieve symptoms, but the long-term effect is not very satisfactory. Therapeutic methods focusing on biological functional recovery have been concerned gradual y, but the clinical application is far in sight. OBJECTIVE:To review the advances in the treatment of lumbar disc degeneration regarding tissue-engineered repair and biomechanics. METHODS:PubMed database was searched by the first author for relevant articles published before December 2014 using the keywords of“intervertebral disc degeneration, clinical treatment, biological treatment, tissue engineering, biomechanics, repair, progress”in English. A total of 100 articles were searched initial y and final y, 40 articles were included in result analysis. RESULTS AND CONCLUSION:Although the therapeutic schemes are varied, the treatment of intervertebral disc degeneration is a great chal enge for clinicians and basic researchers. Currently there is no perfect clinical treatment, and indications corresponding to various therapies should be paid attention as wel as long-term fol ow-up evaluation. For various reasons, the biological treatment for intervertebral disc degenerative disease is becoming more and more popular, providing a promising prospect for the treatment of intervertebral disc degeneration. So far, large amounts of data have been obtained from animal experiments, but there are stil many problems to be solved. Other chal enges also involve the al aspects of general tissue engineering methods, such as cel s, cytokines and scaffolds. In these studies, the nucleus pulposus tissue engineering based on the combination of heparin-functionalized chitosan hydrogel, cytokines and stem cel s exhibits a promising prospect.

Plasma and myocardial angiotensin and aldosterone as well as plasma renin activity were detected by radioimmunoassay. RESULTS: Compared with I/R group, myocardial infarct size was reduced by 23.9% (P

Background and purpose: Cervical nodal metastasis in nasopharyngeal carcinoma plays an important role in the definition of radiotherapy area and clinical staging, it is also one of the main factors influencing prognosis. So this study was designed to explore the pattern of metastatic lymph nodes for patients with nasopharyngeal carcinoma, which may provide a basis for clinical treatment and research. Methods: From Jun. 2005 to Sep. 2007,779 histologically diagnosed nasopharyngeal carcinoma patients had routine MRI scan before radiation therapy at Fujian Provincial Cancer Hospital. Diagnostic radiologists and radiation oncoiogists together assessed the nodal distribution according to the guideline CT-hased delineation of lymph node levels. Then, Chi-sqnare test was used to analyze the correlation between T stage and nodal metastasis rate and between nodal diameter and nodal extracapsular invasion. Results: Of 779 patients, 592(76.0%) had nodal involvement. The distribution was as follows: 1 in level Ⅰ,384 in level Ⅱa, 499 in level Ⅱ_b, 184 in level Ⅲ, 33 in level Ⅳ, 67 in level V_a, 21 in level V_b, 597 in retropharynx.In these patients, a total of 1 479 postive nodes, including 973 (65.79%) extracapsular spread nodes, were detected.The rate of nodal extracapsular invasion was higher when the axial diameter increased. Leap metastasis rate was 1.0%. No significant correlation was found between T stage and nodal involvement. Conclusion: The level Ⅱ and retropharyngeal node were the most frequently involved regions, they had similar metastatic rate and were both the first echo node to metastases of nasopharyngeal carcinoma. Level Ⅰ metastasis was lower. The proportion of extracapsular spread of metastatic lymph nodes increased with axial diameter of lymph nodes-dependent. The cervical node involvement of nasopharyngeal carcinoma was spread orderly down the neck, and the incidence of skip metastasis is rare. The relationship between T stage and nodal involvement has no statistical significance.

Objective To assess the capability of the colon computer-aided-detection(CAD) for the detection of colonic neoplasm on low-dose CT colonography with changing sphericity filter values. Methods Low dose (50 mA) CT colonography data from 56 patients with 159 colonic neoplasms confirmed by conventional colonoscopy and surgery were divided into four groups: colorectal cancer, ≥ 10 mm polyps,5. 1 to 9. 9 mm polyps and ≤ 5.0 mm polyps. The golden standard was established by matching the neoplasms on CT colonography images. The datasets analyzed subsequently by the Colon CAD system at four discrete sphericity filter settings (SFV): 0. 25, 0. 50, 0. 75 and 1.00. The location and size of highlight lesions by the colon CAD were recorded. Comparison was made with the known golden standard in order to determine the detective rate of colonic neoplasms. Chi-square tests were used to compare the detection rates of four groups by CAD SFV at four settings. Results Fifty six patients had 159 colonic neoplasms including 44 colonic cancers, 45 large polyps (max diameter≥ 10. 0 mm), 32 median polyps (max diameter 5. 1 to 9. 9 mm) and 38 small polyps ( max diameter ≤5.0 mm). The colon CAD had the detective rate of 85.5%( 136/159), 85.5% ( 136/159 ), 79. 2% ( 126/159 ) and 56. 0% (89/159) for all colonic neoplasms at four sphericity filter settings 0. 25, 0. 50, 0. 75 and 1.00 respectively. There was statistically significant difference between the sphericity filter settings at 0. 25 and 1.00 ( P ＜ 0. 05). Detective rate was highest at lower sphericity, false-positive rate increased at same time, however, 91.4% ( 138/151 )to 93.9% (31/33 )of false-positives were rapidly dismissible with 2D axial images, only 6. 1% (2/33)to 8.6% (13/151)of false-positives needed to discriminate with multiplanar reconstruction or 3D virtual colonoscopy. Conclusion The Colon CAD system can detect colonic neoplasms satisfactorily in low dose CT colonography and may satisfy the needs of radiologists with different experience by changing sphericity filter settings.

Porcine endogenous retroviruses (PERV) can infect human cell in vitro, which raised widely concerns re-garding the transmission of PERV to xenograft recipients. It's essential to establish a method for detection of PERV.3 pairs of primers were synthesized according to the sequence of gag, pol and env gene of PERV. Polymerase chainreaction (PCR) and reverse transcription PCR (RT-PCR) assays were performed for detection of PERV provirusDNA and PERV specific mRNA. The results showed that provirus DNA and mRNA of PERV existed and expressedin all 4 tested cell lines. The sizes of amplified fragments are identical with the predicted. These methods may be suit-able for monitoring PERV in other cells or tissue.

Aim To investigate the preventive effect of Polygonum Multiflorum (PM)on the deteriorated mi-cro-structure and biomechanical properties induced by prednisone.Methods Ninety 6-month-old male Sprague-Dawley rats were randomly divided into nine groups,which were control,prednisone,CAL,30%ethanol eluent of the PM(H,M,L),PM(H,M,L). Prednisone was gavaged to rat for 21 weeks as model group of osteoporosis.Meanwhile,tested herbal ab-stract were orally administrated to the modeled rats in-duced by prednisone.At the end of the experiment, the right femur was collected for micro-CT scanning, three-dimensional reconstruction and biomechanical test.Results Compared with the control group,mod-el group showed destruction of bone microarchitecture, BV /TV fell 28.6%(P <0.05),bone biomechanical parameters decreases,and stiffness fell 29.7%(P <0.01 ). Compared with the model group, positive group had significantly improved effect on bone micro-architecture,and biomechanical parameters,BV /TV increased 46.7%(P <0.01 ),and stiffness increased 25.9%(P <0.01 ).30% ethanol eluent of the PM (M,L)dose may improve bone microstructure by in-creasing BV /TV 46.7% (P <0.01 ),40.0% (P <0.05)respectively,PM(H)may improve the biome-chanical parameters by increasing stiffness 24.7%(P<0.05),and 30% ethanol eluent of the PM(H)and PMhigh-dose may improve the biomechanical parame-ters,but not as positive group.Conclusions Predni-sone reduces biomechanical properties of rat femur and deteriorates femoral microstructure.30% ethanol eluent of the PM(M,L)and PM(H)plays a preventive role in the changes of micro-structural and biomechanical properties by prednisone,and increases BMD,whereas other groups have no significant preventive effect.
