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 investigate the clinical and laboratory features of auto antibody-negative rheumatoid arthritis(RA).Method The clinical features and laboratory parameters were compared between auto-antibndy-negative(n=30)and-positive(n=217)RA patients.The patients with osteoarthritis(OA,n=34) were used as controls.Results Thirty(12.1%)of 247 RA patients were auto-antibody-negative.It was shown that morning stiffness of the joints in auto-antibody-negative RA was shorter than that of auto-antibody-posi- tive RA patients(P

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 investigate the anti-inflammatory effects and mechanism of durian peel extracts (DPE). Methods The in vivo anti-inflammation effects of DPE were examined by carrageenin-induced mice paw edema test and allergic contact dermatitis test induced by 2, 4-DNFB. And the in vitro anti-inflammation effects of DPE were evaluated with methyl thiazolyl tetrazolium ( MTT) assay in RAW 264.7 cell model of inflammation induced by lipopolysaccharide (LPS). Results The results of animal experiments showed that DPE groups could markedly relieve mice paw edema induced by carrageenin ( P<0.01 or P<0.001 compared with blank group). DPE could effectively inhibit the allergic contact dermatitis induced by 2, 4-DNFB in mice, showing good dose-effect relationship. The results of in-vitro test showed that DPE at the given concentrations had no influence on RAW 264.7 cell proliferation. Tumor necrosis factor alpha ( TNF-α) , interleukin 6 ( IL-6) , interleukin 1 beta (IL-1β), nitric oxide (NO) and nuclear factor kappaB (NF-кВ ) were observably inhibited, and anti-inflammatory cytokine IL-10 was enhanced by 25 and 50 mg/L of DPE. Conclusion DPE exert potential anti-inflammation effect, and the mechanism might be related to its inhibition of NF-кВsignal pathway.

Objective To observe the therapeutic effect of consciousness-restoring needling combined with comprehensive rehabilitation training on motor function and the activities of daily living of poststroke patients with hemiplegia. Methods Sixty qualified patients were evenly randomized into observation group and control group. All of the patients were given conventional medicine treatment and conventional rehabilitation training, and the treatment group was given consciousness-restoring needling additionally. The therapeutic effects were compared at the end of first session of treatment for 4 weeks and 12 weeks after the first session of treatment. The Fugl-Meyer motor assessment scale (FMA), modified Barthel Index (MBI) and Stroke-Specific Quality of Life Scale ( SS-QQL) were taken as the main evaluation indexes. Results The differences of FMA, MBI and SS-QOL scores were insignificant between the two groups before treatment ( P>0.05). At the end of treatment for 4 weeks, FMA, MBI and SS-QOL scores were increased in the two groups (P<0.05), and the increase was more obvious in the observation group (P<0.05). The results of follow-up till the 12th week showed that FMA, MBI and SS-QOL scores were still higher than the baseline level ( P<0.05). Conclusion Consciousness-restoring needling combined with comprehensive rehabilitation training has better effect on improving motor function and the activities of daily living of poststroke hemiplegia patients than comprehensive rehabilitation training alone.

Molecularly imprinted polymers (MIPs) with high selectivity to tilmicosin (TIM) were prepared using tylosin(TYL) as dummy template, methacrylic acid(MAA) as monomer, ethylene glycol dimethacrylate (EGDMA) as cross-linker.The effects of 4 porogens including dimethyl formamide, methanol, acetone, and chloroform on the recognition capability of MIPs were investigated.Orthogonal test was used to optimize the preparation of MIPs, and the optimal composition was as follows; 1.0 mmol TYL, 8.0 mmol MAA, 20.0 mmol EGDMA, 6.0 mL chloroform, 20.0 mg azobisisobutyronitrile.The solid phase extraction condi tions and characteristics of MIPs as adsorptive material for the selective extraction and enrichment of TIM were also studied.The recovery of TIM was above 90% when the following procedure was applied to MIPs cartridge: conditioning with methanol and water(pH 9.0), loading with acetonitrile, cleaning with methanol and chloroform respectively, and eluting with 3 mL methanol-ammonia(95:5, V/V).The recovery of TIM on non-imprinted polymers cartridge was only 32%.

Objective To investigate the imaging features of alar ligament and its extent, and provide the basis forclinical treatment.Methods 3.0 T superconducting MRI was used to scan the alar ligament with high resolution PDWI sequence (Proton density weighted imaging, PDWI)in 109 patients of emergency admissions due to head and neck trauma. Based on imaging features, ligamentous injury was classified into three degrees(Ⅰ to Ⅲ degrees).Patients with Ⅰ degree ligamentous injury were treated conservatively, andⅡtoⅢdegree injury patients were treated with surgery, then follow-up was performed with MRI for the recovery of ligaments and clinical evaluation for symptoms (6 months follow-up period). Results High-resolution PDWI showed 78 patients with no ligament injury.On follow-up, patients recovered well (atlantoaxial joint motor function and clinical symptoms). Thirty one patients had alar ligament injury in varying degrees, of which 18 patients had grade Ⅰ injury, nine patients had degree Ⅱinjury, and four patients had degreeⅢinjury .All gradeⅠinjury patients received conservative treatment. Follow-up of patients showed good recovery, MR revealed the lesions shrank in varying degrees or disappear.
Six gradeⅡinjury patients had surgical treatment, and three received conservative treatment. On follow-up, seven patients had a good recovery, two patients underwent surgical treatment within 3 months after injury and recovered well.Three gradeⅢpatients treated by surgery, and all with good recovery postoperative, and a patient died of respiratory failure. Conclusions High resolution PDWI is an effective tool to evaluate the extent of the alar ligament injury. Grade Ⅰ ligamentous injury patients treated conservatively can achieve good results, GradeⅡandⅢligamentous injury patients should receive surgical treatment early.
