Objective To evaluate the effect of TBL (team-based learning) method in pharmacology teaching for the foreign students of clinical medicine. Methods In the course of pharmacology teaching of the foreign students of clinical medicine, TBL method was performed in the 2012-year students and tradi-tional teaching method was performed in the 2011-year students. After the teaching, students' grades in the ordinary performance, their final exam scores and their evaluation of the two teaching methods were com-pared. Graph pad 5 was used to analyze the data and the t test was performed. Results The average ordi-nary performance of the students with TBL was significantly higher than that with the traditional teaching [(84.94 ±12.66) vs. (72.30 ±4.90), P=0.000] and the final examination scores were significantly im-proved [(74.00±6.76) vs. (69.00±6.20), P=0.023]. The survey showed students were more satisfied with the TBL teaching mode than traditional teaching mode [(8.40±0.71) vs. (7.12±1.07), P=0.000]. Conclusion TBL teach-ing mode can effectively improve the pharmacology teaching effect of foreign students.

Objective To investigate the arthroscopic inside-out repairing technique(hybrid suture technique) for bucket-handle tear of inside meniscus and present the short-term clinical outcome. Methods Twenty patients with 20 repairable inside meniscus tears were enrolled. With arthroscopic technique,the midbody portion and anterior portion of the lesion were repaired using standard inside-out technique with vertical and interlacing tibial and femoral side arrangement. For the most posterior portion, all-inside suture technique with two posterior portals were performed. For isolated red-white zone tears,fibrin clot was implanted into the repaired region for enhancing the healing pro-ACL injuries were reconstructed simultaneously. Results Twenty patients with 20 meniscal repairs were available for 5-36 (19.2 ± 2.3)months follow-up. Eighteen cases were asymptomatic at the latest clinical evaluation,and joint space tenderness in 2 cases. Twenty cases received MRI evaluation during follow-up, showing that 15 menisci were completely healed, 5 partially healed. Postoperative Lysholm scores of the knee joint function [82-97(90.3 ±1.5) points] were significantly improved compared with their preoperative scores [45-69 (56.7 ± 2.0)points] (P = 0.024).Conclusion For meniscal tears involving red-red and red-white zones,arthroscopic hybrid suture technique provides stable strength along the whole length of injured region, and consequently achieves satisfactory clinical outcomes.

Objective:To investigate the craniofacial features in patients with cleidocranial dysplasia (CCD).Methods:The facial features,cervical vertebral bone age and skeletal abnormalities of 8 patients with CCD were studied by analyzing facial photos,cephalo-metric and panoramic radiographs.Results:4 patients were in the early growth stage and the other 4 in the late period of development. The bossing forehead and inclined eye fissure were observed in all patients,but underdevelopment of midfaces were not obviously pres-ented in younger patients.Morphological abnormalities of craniofacial bones,such as ascending ramus,coronoid process,nasal bones and disappearence of gonial angle were observed in all patients.Conclusion:Some craniofacial malformations in patients with CCD may be presented earlier than underdeveloped midface,which can be helpful for early diagnosis of CCD.

OBJECTIVE:To systematically review the effectiveness and safety of methotrexate(MTX)in the treatment of rheuma-toid arthritis,and provide evidence-based reference for clinical treatment. METHODS:Retrieved from Medline,EMBase,Cochrane Library,PubMed,CJFD,CBM,VIP and Wanfang Database,randomized controlled trials(RCT)about MTX in the treatment of rheu-matoid arthritis were collected,Meta-analysis was performed after data extraction and quality evaluation. RESULTS & CONCLU-SIONS:33 effectiveness evaluation were included,involving 8 253 patients,and 53 safety evaluation were included,involving 4 803 patients. Results of analysis show,the efficacy of MTX was not higher than leflunomide in the treatment of rheumatoid arthritis,superi-or to cyclosporine A,and similar to sulfasalazine. In addition,MTX shows similar efficacy with etanercept(7.5-20 mg per week),goli-mumab,adalimumab or rituximab,but less effective than trastuzumab. The incidence of adverse reactions of MTX is high,but mainly mild or moderate,and the most common adverse reactions are gastrointestinal symptoms. Oral administration of MTX is more secure than intramuscular injection and subcutaneous injection.

【Objective】 To investigate cortical thickness changes in the face-head region of the primary motor cortex (PMC) and its effect on survival in amyotrophy lateral sclerosis (ALS) patients. 【Methods】 A retrospective analysis was performed on 105 ALS patients who underwent head MRI scan at the same time. The A4hf (face-head) region of PMC was used as the region of interest (ROI). According to clinical symptoms, patients were divided into two groups: bulbar involvement and non-bulbar involvement. The differences of clinical features and cortical thickness in ROI were analyzed. According to the symptoms of bulbar palsy, physical examination of nervous system and EMG of tongue muscle, the patients with bulbar palsy were divided into lower motor neuron (LMN), upper motor neuron (UMN) and LMN+UMN groups. The differences of bulbar subgroup score and ROI of cortical thickness were analyzed. Age at onset, body mass index, delayed time of diagnosis, bulbar subgroup score, and ROI cortical thickness were included in survival analysis. 【Results】 ① The ROI cortical thickness was significantly lower in bulbar involvement group than non-bulbar involvement group (-0.198±0.87 vs. 0.235±0.95, P=0.017). ② There were no significant differences in the bulbar subgroup scores or cortical thickness of ROI between LMN, UMN and LMN+UMN groups (P>0.05). ③ Survival analysis showed age of onset (HR=3.296, 95% CI:1.63-6.664, P=0.001), delayed time of diagnosis (HR=0.361, 95% CI:0.184-0.705, P=0.003), bulbar subgroup score (HR 0.389, 95% CI:0.174-0.868, P=0.021), and ZRE_ROI cortical thickness (HR=2.309, 95% CI:1.046-5.096, P=0.038) were independent influencing factors of ALS survival. 【Conclusion】 Cortical thickness in A4hf (face-head) region can more objectively reflect UMN signs of region bulbar. In addition to age of onset and delayed time of diagnosis, bulbar subgroup score and cortical thickness of face-head region are also independent influencing factors, and cortical thinning in face-head region is a protective factor for survival of ALS patients.

【Objective】 The involvement of upper motor neuron (UMN) degeneration is crucial to the diagnosis of amyotrophic lateral sclerosis (ALS). This study aimed to determine objective and sensitive UMN degeneration markers for an accurate and early diagnosis. 【Methods】 A total of 108 ALS patients and 90 age- and gender-matched control subjects were recruited from ALS Clinic of The First Affiliated Hospital of Xi’an Jiaotong University. The motor homunculus cortex thickness data in MRI were collected from all the participants. The clinical characteristics and UMN clinical examination of bulbar, cervical, thoracic and lumbosacral regions were collected from the ALS patients. 【Results】 Cortical thickness was significantly thinner in the ALS group than in the control group in bilateral head-face-bulbar and upper-limb areas (P<0.05). The cortical thickness of the global UMN positive group was significantly thinner than that of control groups in bilateral head-face-bulbar and upper-limb areas (P<0.05). The cortical thickness of the UMN positive group in the corresponding region was significantly thinner than that of control groups in bilateral head-face-bulbar and upper-limb areas (P<0.05). 【Conclusion】 The thinning of the motor homunculus cortex can be used as an objective marker of UMN involvement in ALS patients in clinical practice.
