Objective To explore the MRI findings of enthesitis in peripheral ankylosing spondylitis (AS). Methods We retrospectively reviewed the MRI obtained from 13 patients with clinically-diagnosed peripheral AS. MRI finding attributable to enthesitis could be visualized as tendon or ligament enthesitis, bone marrow edema (BME), synovitis, bursitis, tenosynovitis. Results MRI findings of knee showed enthesitis in 8 knees, mainly involved in the insertions of the quadriceps tendon at the upper patellar pole , the patellar ligament at the lower patellar pole and the tibial tubercle, BME in 8 knees, synovitis in 5 knees, bursitis in 3 knees, and tenosynovitis in 4 knees. MRI findings of ankle showed enthesitis in 3 ankles, involved in plantar insertion into calcaneus and Achilles tendon insertion into the calcaneus, BME in 1 ankle, and tenosynovitis in 3 ankles. Conclusion The lower extremities are more often involved in peripheral AS than the upper extremities. MRI characteristic of enthesitis may contribute to the diagnosis of peripheral AS early combined with HLA-B27.

Objective To explore the MRI features in mediopatellar plica and cartilage injury.Methods The MRI appearances of 30 patients with mediopatellar plica were divided into four types and chondral injury were divided into five grades,then the characteristics of MRI imaging were analyzed,and compared with arthroscopy classification.Results The MRI manifestations of A type (n =7) of mediopatellar plica showed a cordlike elevation on the synovial wall;B type (n =13) showed shelf-like appearance but did not cover the anterior surface of the medial femoral condyle;C type (n =8) showed shelf-like appearance and covered the anterior surface of the medial femoral condyle and D type (n =2) showed a central defect in the mediopatellar plica.The MRI manifestations of chondral injury grades included zero grade (n =10),Ⅰ grade (n =2),Ⅱ grade (n =7),Ⅲ grade (n =7) and Ⅳ grade (n=4).There was no statistical significance in terms of classification of mediopatellar plica and grading of cartilage injury via MRI and arthroscopy.Conclusion MRI provides solid evidence for preoperative assessment and choice of operation scheme for classification of mediopatellar plica and grading of cartilage injury in knee.

Objective To explore the application effect of the wechat public platform in follow-up management of patients with moderate or severe craniocerebral injury.Methods 98 patients admitted in the craniocerebral department of our hospital from February to November 2014 were selected and divided into two groups by random number table method,with 48 cases in the control group and 50 cases in the observation group;the traditional follow-up management mode using telephone was adopted to patients in the control group,while the follow-up management mode using the wechat public platform was adopted to those in the observation group,with a follow-up period of 3 months;for patients in both groups,their activities of daily living (ADL) and exercise of self-care agency (ESCA) abilities before and after intervention,occurrence of adverse events and complications within the follow-up period,and their degree of satisfaction towards the follow-up management were collected.Results After intervention,ADL score,total scores of ESCA and total scores of satisfaction towards the follow-up management among patients in the observation group were 87.34±15.26,24.36±17.24 and 86.07±14.82,which were significantly higher than that among patients in the control group were 66.72±14.62,99.37±15.29 and 61.14±13.19 (t=7.941,7.982,6.962,all P ＜0.01);within intervention,the observation group had significantly lower total occurrence rate of adverse events and complications which was16.00％ (8/50) compared to the control group 39.58％ (19/48) (x2=6.824,P ＜ 0.01).Conclusions By establishing the follow-up management mode for patients with craniocrerbral injury through the wechat public platform,effect of the follow-up management can be effectively promoted,prognosis of patients can be improved and patients' degree of satisfaction can be enhanced;it is worth of being further promoted clinically.

ObjectiveTo observe the efficacy of rehabilitation therapy for patients and experimental animals with short bowel syndrome.MethodsThirty SD rats were randomly divided into control group,short bowel group and growth hormone (GH) treatment group.Short bowel was produced by resecting 80% of the rats′ small intestine, growth hormone at a dosage of 1?U/kg?d was delivered to the rats from POD1 to POD28.Nine patients with short bowel syndrome were enrolled in the study,the average length of the small intestine was (44?24)?cm, 3 cases had also suffered a short colon.ResultsIncreased ratio of S phase cells, proliferation index and expression of proliferative cell nucleus antigen (PCNA) were observed, indicating the putative effects of exogenous GH on residual small intestinal mucosa. The mechanism of action was probably through the alteration of protooncogene C-jun. The nutritional state of the patients and the absorptive capacity of the residual intestine improved markedly. Follow up were made to 8 patients,75% of the patients have weaned TPN,25% of them need intermittent TPN supplementation.ConclusionsRehabilitation therapy provides a new and effective alternative for short bowel patients.

Objective: To develop the Chinese version of the Anxiety Sensitivity Index-Revised and examine its replicability, reliability and validity. Methods: This study translated the Anxiety Sensitivity Index-Revised ( ASI-R) and examined the factor analytic structure of anxiety sensitivity in a large sample of middle school students aged 12-18 years (n = 1556) . Factor analysis of the ASI-R items resulted in a hierarchical construct with three lower-order factors loading on a single higher-order factor. Results: after revision, the number of items of the inventory reduced from 36 to 15. Anxiety sensitivity seems to be a hierarchically organized construct with one higher-order factor (anxiety sensitivity ) and three lower-order factors: Physical concern, Cognitive concern (lose of control) , Social concern, which three factors contributed to 52. 29% of total variance. Factor loadings of items were 0. 63 ~ 0. 98 , the internal correlation between items were 0. 37 ~ 0. 53 , the correlation between factors to the total score were 0. 72 ~ 0. 84, internal correlation among factors were 0. 68 ~ 0. 78. internal consistency of each factor 0. 73 ~ 0. 78. the split-half reliability was 0. 71 ~0. 76, that of test-retest was 0. 70 ~0. 78. Conclusion: The questionnaire has satisfying reliability and validity.

Objective ABCG2(ATP-binding cassette superfamily G member 2)is a member of ABC transporter superfamily,and participates in the mechanisms of high resistance to chemotherapeutic agents in tumor treatment.The aim of present study is to investigate the expression and significance of ABCG2 in lung cancer tissues.Methods Lung cancer tissues were obtained from 83 patients(64 NSCLC,19 SCLC)by bio-autopsy or surgery.No patients had received chemotherapy or radiotherapy before bio-autopsy or surgery.83 lung cancer specimens were analyzed for ABCG2 protein expression by using immunohistochemistry.Negative controls had the primary antibody eliminated.Human placenta tissues were used as positive control.In addition,five specimens of normal lung tissues were included for comparative study.Results The present study confirmed the predominant localization of ABCG2 transporter in plasma membrane.Some of ABCG2-positive tumors showed mixed membranous and cytoplasmic staining.ABCG2 expression was found in 71.9%(46/64)of NSCLC and 10.5%(2/19)of SCLC.The level of ABCG2 expression was significantly higher in NSCLC than in SCLC(P

Aim To evaluate the inhibitive effects of celastrol on LDL oxidation and HAEC cell oxidative damage. Methods The Cu2+-induced LDL oxidation model was employed to evaluate celastrol inhibitive effect on LDL oxidation in vitro, the oxidative reaction kinetic curves were determined, and the AUC, lag time,TBARS value were assayed. The AAPH-induced HAEC damaging cellular model was employed to evalu-ate the effect of celastrol on oxidative cellular damage. The safe dose of celastrol on normal cells was deter-mined by MTT method, and the effects of celastrol on HAEC oxidative damage were evaluated at the range of this safe dose. The LDH leakage,ROS level,SOD and GPX enzymatic activity,Nrf2 and HO-1 mRNA expres-sion were determined. Results At the dose range of 100 nmol · L-1 to 1 μmol · L-1 , celastrol effectively extended the lag time of LDL oxidative process induced by Cu2+, reduced the AUC of oxidative reaction kinet-ic curve and reduced the generation of lipid peroxide in the LDL oxidative process. In the cellular experiment, celastrol effectively reduced the LDH leakage induced by AAPH, increased the integrity of cell membrane and nucleus, enhanced the antioxidative enzyme activi-ties of cellular SOD,GPX and increased the expressions of Nrf2,HO-1 mRNA, celastrol also maintained the in-tegrity of cellular structure. Conlusion Celastrol can effectively inhibit LDL oxidation induced by Cu2+, and can inhibit HAEC cell oxidative damage induced by AAPH at the dose range of 100 to 400 nmol·L-1 .
