Objective To investigate the situation of visual memory impairment in patients with myasthenia gravis (MG).Methods Thirty MG patients and 28 normal control subjects were tested with a battery of computerized tests (modified Smith working memory software), which was designed to assess visual-spatial and visual-object working memory.Results There was no significant difference in the accuracy rate of visual-object working memory test between the MG group and normal controls (MG group 73.4% ±9.7%, normal controls 72.7% ±8.5%).The accuracy rate of the visual-spatial working memory test in the MG group (76.6% ± 16.5%) was significantly lower than that in the normal controls (86.6% ±7.5%, Z = -2.204, P = 0.028).Conclusion The visual-spatial working memory is probably impaired while the visual-object working memory is relatively spared in MG patients.

Objective To investigate the characteristics of family environment in children with attention deficit hyperactivity disorder (ADHD) in clinics, and analyse the risk factors for ADHD. Methods Two thousand two hundred and ninety-six children with inattention, hyperactivity or unfavourable school performance were subjected to diagnosis with DSM-Ⅳ criteria in clinics. The characteristics of family environment were investigated by self-prepared questionnaires. The risk factors for ADHD were explored by univariate analysis and noneonditioned multivariate Logistic regression analysis. Results Seven hundred and twenty children were diagnosed with ADHD. There were significant differences in family environment between children with ADHD and those without(P<0.05 or P<0.01). The risk factors for ADHD included discord between parents, parental smoking and maternal depression during pregnancy and after delivery, while older age, female, paternal higher educational background were protective factors for ADHD. Conclusion Unfavourable family environment may be associated with the prevalence of ADHD, and special attention should be paid to the family environment in the treatment of ADHD.

Statement of the REporting of studies conducted using routinely collected data (RECORD) and evaluating checklist of good research for comparative effectiveness (GRACE) were translated and introduced in this paper. The two evaluation tools would help researchers of Chinese medicine to conduct real world study in future. RECORD statement focus on unique aspects of studies conducted with routinely collected health data and the perceived need for better reporting of methodological issues. Researchers of comparative effectiveness research could refer to GRACE checklist. It was believed that researchers of Chinese medicines who were keen on real world studies would be benefited from the two tools.

Objective:To evaluate the surgical corrective results of maxillary hypoplasia in patients with cleft lip and palate withtranspalatal modified Le Fort Ⅰ osteotomy.Methods:In the study,1 1 patients (4 women,and 7 men)with maxillary hypoplasia secondary to cleft lip and palate underwent transpalatal modified Le Fort Ⅰ osteotomy at Peking University School of Stomatology from Jan.201 2 to Dec.201 3, with the mean age of 21 years (from 1 8 to 27 years),Bilateral sagittal split ramus osteotomy (BSSRO) and genioplasty were performed simultaneously in 9 of them for better appearance and functional occlu-sion.Lateral cephalometric radiographs were taken and traced before surgery,immediately after surgery and 6 months after surgery.The position of subspinale (A)on horizontal direction,the angle of sella-na-sion-subsipmale (SNA)and the angle of sella-nasion-supramental (SNB)were collected and analyzed to evaluate the results.Results:All the patients were uneventful with transpalatal modified Le Fort Ⅰosteotomy.All of them had a better profile and a satisfactory occlusionafter operation.The position of A was moved forward (6.6 ±1 .1 )mm on average in horizontal direction when surgery was completed,and maintained (6.0 ±1 .2)mm on average 6 months after surgery.The average of SNA was 75.9°±2.8° before surgery,81 .6°±8.6°immediately after surgery,and maintained 81 .0°±2.6°6 months after sur-gery.The average of SNB was 82.6°±3.7°before surgery,78.0°±2.4°immediately after surgery,and maintained 78.5°±2.4°6 months after surgery.Conclusion:The maxillary hypoplasia in cleft lip and palate patients can be successfully corrected with transpalatal modified Le Fort Ⅰ osteotomy and the func-tional occlusion can be achieved simultaneously.The effect of deformity correction was satisfactory. Transpalatal modified Le Fort Ⅰ osteotomy can move maxilla more sufficiently,especially applicable for the patient with severe palatal scars preoperatively.
