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.

Objective To investigate the clinical features and pathogenic genes of a familial hypokalemic periodic paralysis ( HOKPP).Methods PCR amplification and DNA sequencing were used to screen candidate genes of the HOKPP family members (CACNA1S, SCN4A, KCNE3), and the clinical features were carefully analyzed at the same time.Results The sequencing analyses of the SCN4A gene in the proband identified three nucleotide sequence mutations, which influenced the amino acid sequence of the skeletal sodium channel.One of the mutations was identified as a C/T heterozygous pattern at the 2111th nucleotide position in exon 13, resulting in a change from Thr to Met at the 704th amino acid position of the sodium channel protein.All affected patients carried the Thr704Met mutation, whereas unaffected family members did not.Clinical symptoms in this family followed an autosomal dominant inheritance pattern.Muscles weakness, pain and hypokalemia in the period between attacks were seen in all patients.Paralytic symptoms occurred early, lasted longer and recurred frequently, while cold was the main predisposing factor.With the progress of the disease, patients represented persistent weakness and atrophy in proximal muscles.Conclusions Mutation (Thr704Met) in the SCN4A gene should be responsible for this family.This mutation causes severe HOKPP and progressive muscle atrophy.

Non-small-cell lung carcinoma (NSCLC) is one of the most frequently diagnosed malignancies worldwide.Previous studies have shown that microRNA-449b (miR-449b) functions as a tumor suppressor in many cancers.However,the role of miR-449b in NSCLC is still unknown.In the present study,miR-449b was significantly downregulated in NSCLC samples and cell lines.Bioinformatics analysis revealed that 3'-UTR region of leucine rich repeat containing G protein-coupled receptor 4 (LGR4) mRNA had putative complementary sequences to miR-449b,which was further confirmed by the luciferase assay.Western blotting showed that restoration of miR-449b in NSCLC cells decreased the expression of LGR4.Interestingly,over-expression of miR-449b inhibited growth and invasion of NSCLC cells in vitro.Furthermore,ectopic expression of LGR4 reversed miR-449b-suppressed proliferation and invasion of NSCLC cells.Therefore,the data of the present study demonstrate that miR-449b inhibits tumor cell growth and invasion by targeting LGR4 in NSCLC.

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.
