Objective Poly (ADP-ribose) polymerase (PARP) have been demonstrated to play an important role in systemic lupus erythematosus (SLE). In this study we assessed the expression of PARP on peripheral blood mononuclear cells with active or inacte SLE and tried to investigate the relationship between PARP and cell apoptosis on SLE. Methods Thirty definitive SLE patients and 10 healthy controls were enrolled. PBMC were separated from the peripheral blood samples. Western blot technique was applied to analyze the expression of PARP. Flow cytometry were applied to analyze the cell apoptosis. T test were used. Results The cell apoptosis in active patients with SLE was significantly higher than that of inactive patients with SLE and normal controls (the t values were 4.83 and 5.05 respectively, P<0.05). The level of PARP expression was significantly decreased in active patients with SLE as compared with controls and inactive patients with SLE (the t values were 7.66 and 7.07 respectively, P<0.05). At the same time, the cleavage fragment of PARP increased in active patients. Conclusion The results suggest that PARP may be involved in the pathogenesis of SLE and the expression level may be a good indicator for disease activity of SLE . Decrease of PARP may promote the occurrence and development of SLE. In addition, PARP may play a certain role in adjusting cell apoptosis in patients with SLE.

Objective To investigate the expression of T cell immunoglobulin domain and mucin domain (TIM)-3 and its ligand Galectin-9 in the peripheral blood of initial systemic lupus erythematosus (SLE)patients,and explore their effects on SLE.Methods The percentages of CD4+TIM-3+,CD8+TIM-3+cells from 33 SLE patients and 26 normal controls were detected by flow cytometry,and the Galectin-9 gene expression of PBMCs was determined by real-time PCR The SLE Disease Activity Index(SLEDAI),C3 level and lymphocyte count were evaluated.Mann-Whitney U test was used for independent samples analysis and Spearmen's test was used for correlation analysis.Results The percentages of CD4+TIM-3+ and CD8+TIM-3+ cells were markedly increased in SLE group than those of the control group(P<0.01).In particular,the CD4+TIM-3+,CD8+TIM-3+ level Was positively correlated with SLEDAI (r=0.517,P＜0.01;r=0.400,P＜0.05);but negatively correlated with C3(r=0.487,P＜0.05;r=0.395,P＜0.05).The Galectin-9 mRNA in SLE PBMCs was higher than that of the controls(P<0.05).Conclusion TIM-3-Galectin-9 pathway may be involved in T cell immune regulation of SLE,and is related to disease activity.

Objective To determine health related quality of life (QOL) of patients with systemic lupus erythematosus (SLE) and to identify the factors affecting QOL. Methods One hundred and fifty-one consecutive patients with SLE were separated into different groups according to the type or stage of disease. Health status were measured by 1 health transition (HT) and 8 composite scales of the medical outcomes study short form-36 (SF-36). The mean scores for each subscale of the SF-36 for patients with SLE in China were compared to those of a health population in China and of foreign SLE patients.The effect of patients′age,sex,education level,disease duration,disease activity (assessed by SLEDAI score),and organ damage(assessed by SLICC/ACR DI) and treatment were analyzed. ANOVA, rank sum test and correlation analysis were applied for statistical analysis. Results Patients with SLE had significantly lower HT and mean scores in each subscale of the SF-36 compared to those of a health population in China,while the scores in such subscales as physical functioning (PF), bodily pain (BP), vitality (VT), role-emotional (RE) and mental health (MH) were higher than those of foreign SLE patients. The mean scores of those patients with lupus nephritis and center neural lupus or in active state were lower than those not or those in steady-going. The SLEDAI score and SLICC/ACR DI were the most important elements that affected the QOL in SLE patients and showed obviously negative correlated with one′s scores in SF-36. The glucocorticoid dose of patients was closely negatively correlated with one′s scores. The latter were also associated with age, education level and disease duration. Conclusion The health status of patients with SLE is mainly associated with disease activity,damage and therapy. The SF-36 is a valid instrument for measuring the health related QOL in SLE.

The development trend of medical education is comprehensive, which is character-ized by breaking the boundaries among different disciplines, constructing a main line centering on or-gan and system, and implementing student-centered problem-based learning. This paper analyzed the main problems of basic medical education in Wuhan University of Science and Technology, such as insufficient teaching reform to promoting students' autonomous learning and failed to create excellent teaching and research group et al. Also, the paper proposed comprehensive reform measures such as integrating teaching units , establishing Teacher Education Development Center, implementingCourse director andTeam leader system, promoting teaching model ofstudent centered and in-tegrating curriculums of basic medicine to establish course model centering on the organ and system et al, with some success.

How to remove the well fixed cement or cementless prosthesis and get a completely distal cement removal in the rTHR are critical to the outcome of revision. Because of higher rate of union, excellent intraoperative exposure, and adjustment of abductor tension, ETO has been widely applied to rTHR and complicated primary THR by foreign scholars. Furthermore, this technology has wide indications, very few contraindications, high cure rates,and low complications rate. ETO turns out to be a safe and effective revision technology. In the article, the indication, contraindication, complications and advantages of this technique were reviewed.

Objective To investigate the iodine nutrition level of the vulnerable population in the high risk region of iodine deficiency disorders for providing a scientific basis for the development of effective preventive measures in Qinghai province. Methods The non-iodized salt coverage rate ＞ 5％ of Delingha city, the coverage rate of iodized salt and the rate of qualified iodized salt ≤80％ of Jiuzhi, Wulan, Nangqian, Zaduo, Geermu,Yushu, Gande, Chengduo, and Dulan counties(cities), the median of urinary iodine ＜ 100 μg/L of Huangyuan county of 11 areas were chosen as monitoring area in 2009. Five townships(towns) were selected by their location of east, west, south, north and center in each county (city), and one school was selected in each township (town),and 60 household salt samples were collected in each school, and quantitatively determined by direct titration of iodine(GB/T 13025.7-1999). Three townships(towns) were selected in each county(city), and two schools were selected in each township(town). The content of urinary iodine of 40 children aged 8 - 10 and 20 women of childbearing age aged 18 - 40 was analyzed by As3+-Ce4+ catalytic spectrophotometry (WS/T 107-2006). ResultsThree thousand two hundred and sixty-one edible salt samples were tested. The coverage rate of iodized salt was 79.88％.The iodized salt qualification rate was 95.16％. The qualified iodized salt consumption rate was 76.02％. The noniodized salt coverage rate was 20.12％. In Nangqian, Zaduo, Yushu and Geermu counties(cities), the non-iodized salt coverage rate was 88.89％, 45.05％, 43.00％ and 12.67％, respectively. The median of urine iodine of 2536 children aged 8 - 10 was 155.8 μg/L, with ≤50 μg/L about 13.6％ (346/2536), ＞ 100 μg/L about 67.5％(1711/2536), and it was 75.1, 94.6 μg/L in Nangqian and Zaduo counties, respectively. The median of urine iodine of 665 women of childbearing age was 129.7 μg/L, with ≤50 μg/L about 22.7％(151/665), ＞ 100 μg/L about 59.2％(394/665), and it was 21.0, 54.7, 72.7 μg/L in Zaduo, Nangqian and Chengduo counties, respectively.Conclusions Insufficient intake of iodine exits in children and women of childbearing age in high risk region of iodine deficiency disorders in Qinghai province, which should be corrected as soon as possible.

AIM: To evaluate the changes of corneal high - order aberration (including Coma, Spab, RMSh) after laser in situ keratomileusis (LASIK) with femtosecond laser, sub- Bowman keratomileusis ( SBK ) and laser epithelial keratomileusis (LASEK). METHODS: Of 82 myopic patients ( 164 eyes ), 31 patients (62 eyes) were treated by FS-LASIK, 31 patients (62 eyes) were treated by SBK, 20 patients (40 eyes) were treated by LASEK. Sirius system was used for measuring the coma aberration, spherical aberration, and high order aberration at 1, 15d,1, 3mo after surgery. RESULTS: 1) Vision: The uncorrected visual acuity of the three groups had no differences (P>0. 05). 2) Corneal aberrations: Three kinds of surgical procedure for patients with corneal aberration had significant impact. The C7, C8, C12 and RMSh of three groups were increased significantly (P<0. 05). The C7, C8, C12 and RMSh were not recovered to preoperative levels after 3mo. But the increase of patients after FS- LASIK was smaller than the other two groups, with statistical significance (P<0. 05). CONCLUSION: Compared with SBK and LASEK, FS - LASIK has better visual acuity in the early postoperative and corneal higher-order aberrations increase is relatively small.

Objective To investigate the proliferation characteristics of fibroblast like synovial cells (FLS)in osteoarthritis in vitro and the mechanism of the immnnosuppressive effect of T-614 [N-(3-formy- lamino-4-oxo-6-phenoxy-4H-chromen-7-yl)methanesulfonamide ] on them.Methods FLS of OA and non- inflamed synovium(NS)were cultured and identified in vitro in the presence or absence of T-614.After incu- bation,the survival fraction(SF)of FLS was evaluated by MTT,cell cycle was observed using fluorescence - activated cell sorting(FCS)method and the expression of c-fos and COX-2 mRNA was examined by RT- PCR in FLS of OA patients.Results No statistically significant difference was noted between the OA and NS FLS in proliferation ability and cell cycle.High dose T-614 suppressed FLS SF obviously in OA and NS sta- tistically(P＜0.05),whereas the inhibition degree was not different between the two kinds of FLS.The agent induced cell apoptosis and reduced the accumulation of c-fos mRNA in OA-FLS at dose 1000 ml/L,prolonged G_1 term and shortened S term at dose 200 ml/L.The expression of COX-2 mRNA in OA FLS was suppressed obviously by T-614 at dose 1000 ml/L.Conclusion OA FLS do not display a distinct activated unlimited viability compared with NS cells,without stimulated by proinflammatory cytokine in vitro.High dose T-614 moderately inhibits the proliferation and differentiation of FLS,directly affects gene of the c-fos and COX-2 expression in OA,which may contribute to its immunosuppressive effect on OA'synovitis.
