Objective To investigate the diagnostic value of measurement of SARP2 methylation in peripheral blood for detection of pancreatic cancer in human. Methods Peripheral vein blood of 12 patients with primary pancreatic cancers, 10 patients with chronic pancreatitis and 6 health volunteers were collected. Serum free DNA were extracted from blood samples, and were modified with bisulfate, and SARP2 gene extron 1 were amplified through BSP and sequencing of the production. Results There were 12 patients (83 %) with pancreatic cancer and 10 patients (40%) with chronic pancreatitis had obvious methylation in SARP2 gene in peripheral blood. The rate of CpG methylation in SARP2 gene extron 1 of pancreatic cancer, chronic pancreatitis and health volunteers was 16. 8% , 10. 4% and 2. 2% respectively. There was statistically significant difference among the three groups (P<0.01 or P< 0.05). Conclusions Aberrant methylation of SARP2 gene could be detected in peripheral blood in patients with pancreatic cancer, the detection of SARP2 gene methylation may have potential clinical implication for diagnosis of pancreatic cancer.

OBJECTIVETo evaluate the clinical results after arthroscopic rotator cuff repair using a suture-bridge technique in late middle-aged adults.
METHODSA retrospective analysis of 30 patients with rotator cuff tears, who were treated consecutively between December 2012 and December 2013 at our clinic, was carried out to evaluate the outcome of arthroscopic suture-bridge technique. The visual analogue scale (VAS), the range of motion (ROM), the rating scale of the University of California at Los Angeles (UCLA), and the shoulder index of the American Shoulder and Elbow Surgeons (ASES) were determined as the evaluation criteria.
RESULTSThe mean follow-up period was 13 months. The follow-up rate was 100%. The study included 0 small, 16 medium, 12 large and 2 massive rotator cuff tears. At the latest follow-up, the VAS score decreased significantly from preoperative 6.3±3.2 to 0.8±1.4 at rest,and from preoperative 7.7±2.1 to 1.7±1.6 during motion. The UCLA score improved significantly from 15.1±4.6 preoperatively to 31.2±5.0 at follow-up. The ASES shoulder index improved significantly from 30.2±16.0 preoperatively to 80.4±13.0 at follow-up. The ROM improved significantly. The satisfactory rate was 94%. There were no complications.
CONCLUSIONThe results of this study indicate that the arthroscopic suture-bridge technique is an effective and reliable treatment for patients with rotator cuff tear in late middle-aged adults.

This study was purposed to detect the methylation status in promoter region of RUNX2 gene and its expression in cell lines and patients with HOX11(+) T-cell acute lymphoblastic leukemia (T-ALL) and to explore the relationship between the expression level of RUNX2 gene and methylation of CpG island in its promoter region. The methylation pattem in promoter region of RUNX2 gene was detected with bisulfite sequencing PCR, DNA methylation immunoprecipitation technique and promoter oligonucleotide microarray analysis and the expression levels of RUNX2 mRNA was detected with RT-PCR in 3 T-ALL cell lines (sil-ALL, DND41 and RPMI), as well as in 75 clinic bone marrow samples including 38 de novo T-ALL patients, 29 complete remission T-ALL patients and 8 normal samples. The results showed that there were hypermethylation of CpG island in promoter region of RUNX2 gene in patients with highly expressing HOX11(+) T-ALL. The methylation rate of the promoter CpG islands of RUNX2 gene in HOX11(+) T-ALL (78.9%) was significantly higher than that in HOX11(-) T-ALL (36.8%) (P < 0.01). The expression of RUNX2 in HOX11(+) cell lines was significantly lower than that in HOX11(-) cell lines, and the expression level of RUNX2 in the HOX11(+) T-ALL patients (0.581 ± 0.257) was significantly lower than that in HOX11(-) T-ALL patients (0.835 ± 0.317). The relationship between RUNX2 and HOX11 mRNA expression level showed a negative correlation (rs = -0.378, P < 0.01). The expression levels of RUNX2 gene negatively correlated with the methylation of CpG island in its promoter region (rs = -0.419, P < 0.01). It is concluded that HOX11 is a negative regulator of RUNX2 gene and the expression of RUNX2 is down regulated or even lost by promoter methylation in T-ALL, which demonstrate a better event-free survival and a marked trend for longer overall survival for HOX11-high T-ALLs. The expression and methylation level of RUNX2 gene may have some significance in evaluating the curative effect of T-ALL. The abnormal expression of RUNX2 may be a prognostic marker in T-ALL patients.

Objective To establish animal model of arterial vulnerable plaques for molecular imaging study.Methods Fifteen New Zealand white rabbits were randomly divided into high lipid diet+balloon-injury group (A),high lipid diet group (B)and regular diet group (C).Ultrasound (US)and magnetic resonance (MR)imaging were used to dynamically observe the formation of plaque in abdominal aorta. Results were compared with blood lipid level and pathological indicators.Results At 4 weeks,several plaques could be seen in group A.The plaque number increased rapidly and reached to 22 at 12 weeks,which was in parallel with the change of blood lipid. Only a few plaques were observed in group B,while no vulnerable plaque was revealed in group C.All the plaques were judged to be soft plaques on US and MR images,which was consistent with the macrophages gathering and smooth muscle cell proliferating in plaques.Conclusion High lipid diet+balloon-injury is an ideal method to build animal model for molecular imaging of atherosclerotic plaque.

Journal of Experimental Hematology 2009;17(2):377-381
The purpose of this study was to evaluate the expression of cyclin A1 mRNA in patients with myelodysplastic syndrome (MDS) and its clinical significance. The expression of cyclin A1, cdk2 and p21(cip1) mRNA in the bone marrow from 56 patients with MDS and 10 normal control were measured by using reverse transcription polymerase chain reaction (RT-PCR) technique. The results indicated that the positive rate and the expression level of cyclin A1 in MDS patients (69.64%; 0.964 +/- 1.879) were significantly higher than those in normal control (0%; 0.012 +/- 0.014) (p < 0.01). Among de-novo MDS patients, the expression level of cyclin A1 mRNA in the MDS-RAEB group (1.895 +/- 1.769) was higher than that in MDS-RA group (0.629 +/- 1.583) (p < 0.01). The expression level of cyclin A1 mRNA in post-treatment group was significantly lower than that in prior-treatment group (p < 0.01). It is concluded that the mRNA expression of cyclin A1 in MDS patients is higher than that in normal control, the abnormal expression of cyclin A1 may be used as a prognostic marker in MDS patients.

Objective To investigate the effects of aquatic Taiji Quan on balance function of patients with incomplete spinal cord injury. Methods From March to December, 2015, 30 patients with incomplete spinal cord injury received aquatic Taiji Quan exercise based on rou-tine rehabilitation, 30 minutes every day, five times a week for five weeks. They were assessed with Berg Balance Scale (BBS) before and after exercise. Dynamic balance function and static balance function were also assessed with Active Balancer assessment. Results The BBS score significantly improved after exercise (t=-9.652, P<0.001). The track length and area of gravity movement with eyes open and closed decreased (t>3.528, Z>-2.590, P<0.01). No improvement was observed in the deflection center displacement of X and Y axes (P>0.05). The dynamic stability limit range enlarged (t=-4.516, P<0.01), and the time to target significantly shortened (t=4.530, P<0.001). Conclusion Aquatic Taiji Quan can improve the balance function of patients with incomplete spinal cord injury.

?AlM: To investigate the expression of miR-181 in the lens tissue of cataract and the regulating mechanism of miR-181 on apoptosis of human lens epithelial cell.
?METHODS:Real time q-PCR was used to measure the expression of miR-181 in the anterior lens capsules of age - related cataract and human lens epithelial cell apoptosis model. miR- 181 mimic and inhibitor were transfected using Lipofectamine 2 000 to regulate the expression of miR-181, and then Real time q-PCR was used to verify transfection efficiency. Flow cytometry was used to detect the change of cell apoptosis rate.
? RESULTS: Compared with control group, the expression of miR-181 was significantly higher in both the anterior lens capsules of age-related cataract and human lens epithelial cell apoptosis model; the relative expression of miR-181 in lens epithelial cells transfected with miR-181 mimic was increased, whereas decreased in cells transfected with miR-181 inhibitor;the apoptosis rate of cells transfected with miR - 181 mimic was increased, while reduced in miR-181 inhibitor group. Each result was statistically significant (P<0. 01).
?CONCLUSlON:High expression of miR-181 is detected in anterior lens capsule of age-related cataract. miR-181 might play a certain role in the pathogenesis of cataract via promoting human lens epithelial cell apoptosis. miR-181 probably becomes a new approach for the nonoperative treatment of cataract, but the concrete mechanism still needs to be further studied.
