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 learn the prevalence and trends of Brucella disease in Ningxia, in order to provide scientific basis for effective control of the disease. Methods Data of Brucella cases reported through city network from 2004 to 2009 in Yinchuan city, Shizuishan city, Wuzhong city, Guyuan city and Zhongwei city of Ningxia were reviewed and retrospectively analyzed. The data included demographic characteristics, treatment conditions and medical history so on related information. Analytical indicators include reported incidence;with patients' gender, age, regional distribution, urban and rural distribution;become chronic and associated factors;distribution of the cases reporting unit and so on. Results From 2004 to 2009, Ningxia had reported 349 cases of Brucellosis, no deaths, the annual incidence rates reported were 0.017/10 million, 0.543/10 million, 0.151/101 (295/54);The proportion of 34- to 40-year-old age group was higher than other age groups(27.5%, 96/349);Occupational distribution of patients was mainly farmers and herdsmen(70.2% ,245/349), in regional distribution of the patients, the highest percentage was Wuzhong city(61.9%,216/349), followed by Yinchuan city(22.9%,80/349);The proportion of patients in rural areas(97.4% ,340/349) was higher than urban(2.6% ,9/349);the proportion of patients converted to chronic was 11.2% (39/349). With age, the chance of patients converted to chronic was in a decreasing trend(odds ratio was 0.966);cases reported by Centre for Disease Control and Prevention accounted for 74.8%(261/349), by hospital accounted for 25.2%(88/349). Conclusions The reported incidence of Brucellosis in Ningxia is in a rapid upward trend year by year, the patients is mainly young men, the rate of converted to chronic is higher and the ability of hospital in founding and reporting of the cases is weaker.Comprehensive measures should be taken to increase funding, strengthen monitoring, and continuously improve the level of awareness and diagnosis of medical personnel for further strengthen the prevention and control of Brucellosis.

?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.

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.

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.

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.

Harmful substances are produced during the metabolism of alcohol in the human body, which causes liver disease.The mechanism of oxidative stress is the main pathogenesis of alcoholic liver disease, which plays a major role in the occurrence and development of alcoholic liver disease.Alcohol-induced oxidative stress mediated by reactive oxygen species(ROS)/reactive nitrogen species(RNS) brings about liver disease via apoptotic signaling pathway and MAPK signaling pathway, and alleviates liver disease through Nrf2 signaling pathway.In this paper, the studies on the mechanism of oxidative stress in alcoholic liver disease are reviewed.
