Objective To investigate the effect of manual operation on occupational therapy teaching. Methods 83 students were randomly divided into 2 groups: 41 students of general teaching group and the other 42 of manual operation teaching group, who received the ordinary classroom teaching and manual operation teaching respectively. After 4 h of study, they were measured with Canadian Model of Occupational Performance (CMOP). Results There were 37 and 41 questionnaires recalled from the general teaching group and the manual operation teaching group, and 2 and 3 questionnaires excluded as incomplete respectively. The scores of the classroom atmosphere, interesting stimulation, explanation of curriculum connotation, obtaining professional ideology, ability cultivated to solve practical problems, good relationship between doctors and patients developing, and thinking of discussion stimulating were more in the manual operation teaching group than in the general teaching group (P<0.01). Conclusion Manual operation is a new, effective, convenient, and low-cost mode of teaching for occupational therapy.

To screen and identify the possible pathogen of the firstly confirmed human case of avian influenza A in Beijing, the throat swabs and tracheal aspirates of this case were collected and the H5N1 viral nucleotide was tested with real time RT-PCR. The certification of result, screening of other pathogens in respiratory tract and sub-typing of influenza viruses were made by using re-sequencing microarray. It was found that the H5N1 viral nucleic acid was positive in the tracheal aspirate of this case by means of detection with real time RT-PCR and the specific sequence of the non-structural protein (NS) gene of H5N1 virus was obtained through the detection with re-sequencing clip. Through the comparative study with the sequence in Genbank, it was proved to be the H5N1 nucleic acid of avian influenza viruses and excluded the possibility of infections with 30 subtypes of influenza viruses and 33 other respiratory tract pathogens. It is apparent that the pathogen detection with re-sequencing clip shows the high sensitivity and specificity and it plays an important role in the pathogen screening and identification for the firstly confirmed human case of avian influenza A in Beijing.

Purpose To investigate the diagnosis,differential diagnosis and clinical manifestation of primary plasma cell leukemia (PPCL) and lymphoma with increased plasma cell.Methods Through clinical data and cell morphology,flow cytometry (FCM),immunofixation electrophoresis and immunohistochemistry of EliVision two-step examination were used to analyze 7 cases of PPCL and 3 cases of lymphoma with increased plasma cell.Results All patients with PPCL and lymphoma with increased plasma cell presented with anemia,thrombocytopenia,fever,liver and spleen and lymph node swelling.The proportion of plasma cells in peripheral blood morphology were larger than 20％,accompanied by morphological abnormality.FCM of peripheral blood showed all 7 cases of PPCL expressed CD38 and CD138,CD56 expression in the 2 cases and CD20 in the 2 cases.The light chain (Lamda,Kappa) showed a monoclonal restricted expression,which was consistent with the diagnosis of PPCL.CD19 and CD45 were weakly positive in 3 cases of lymphoma with increased plasma cell,CD38 and CD138 were positive,and no restricted expression was found in light chain IgL,wich belonging to the immunophenotypes of normal plasma cells.Of 3 cases of light chain (Ig) without restrictive expression,2 of them were angioimmunoblastic T-cell lymphoma (ATCL) and 1 case was CD30-positive sinusoidal large B-cell lymphoma (CD30 + SLBCL) that confirmed by lymph node biopsy and pathological examination.Conclusion The PPCL and lymphoma with increased plasma cell have the same clinical manifestations and similar morphological characteristics of blood cells.The diagnosis of PPCL should be combined with immunoelectrophoresis and FCM,and the diagnosis of lymphoma with increased plasma cell needs to be confirmed by histological examination of lymph nodes.

Objective To study the effects of ankle-foot retractor on ankle joint motion and equilibrium function of stroke hemiplegic patients.Methods 74 patients were divided into two groups: observation group (n=36) and control group (n=38). The control group was trainedby routine rehabilitation training program and electro-uprise bed, the observation group was trained by ankle-foot retractor based on routinerehabilitation training program. The effect was evaluated after 8 weeks. Results After training, either the observation group or the controlgroup showed significant improvement at motion of ankle joint, activity of daily living (ADL), and equilibrium function, but the observationgroup was better than the control group (P<0.001). Conclusion Ankle-foot retractor plays a positive role on motion of ankle joint, ADL andequilibrium function in stroke patients.

Objective To report a familial dentinogenesis imperfecta type Ⅱ (DGI type Ⅱ) with a novel splicing mutation in DSPP (dentin sialophosphoprotein) gene.Methods Based on the result of linkage analysis performed previously to map the candidate gene DSPP in the family, the promoter,the first four exons and exon-intron boundaries of DSPP were directly sequenced for the members of the DGI type Ⅱ family. Denaturing high performance liquid chromatography (DHPLC) analysis was performed to confirm the results of sequencing.Results A novel splicing mutation of 23 bp deletion in intron 2 of DSPP gene was identified by DNA sequence analysis. The mutation changed acceptor site sequence from CAG to AAG, and might result in functional abolition of possible branch point site in intron 2. DHPLC result was consistent with that of sequencing. The mutation may be identified in all affected individuals, but not found in normal members of the family and 50 controls.Conclusion These results suggest the deleted mutation of DSPP gene causes DGI type Ⅱ in the family. The mutation has not been reported before.

Objective:To analyze the characteristics of peripheral blood lymphocyte subsets in patients with relapsed neuromyelitis optica spectrum disorder (NMOSD) during rituximab (RTX) treatment and to clarify the influence of these lymphocyte subsets in NMOSD relapse.Methods:The monitoring data of lymphocyte subsets (175 times) in 76 patients diagnosed as having aquaporin-4-immunoglobulin G (AQP4-IgG)-seropositive NMOSD during RTX treatment at Department of Neurology, General Hospital of Chinese People's Liberation Army from August 2018 to August 2023 were collected. A relapse group ( n=26) and a non-relapse group ( n=149) were divided based on states at data collection (relapse or not). Two-sample t-test or Mann-Whitney U test were used to compare the differences in RTX administration intervals and lymphocyte subsets between the 2 groups. Additionally, a point biserial correlation analysis was performed to investigate the correlations of lymphocyte subsets and RTX administration intervals with NMOSD relapse. Results:The relapse group had significantly longer RTX administration intervals (10.00 [6.73, 14.37] months vs. 7.27[6.30, 9.10] months), statistically lower percentage of CD3 -CD56 + natural killer lymphocytes (10.72% [7.06%, 15.34%) vs. 13.85% [9.42%, 20.13%]), and significantly higher CD19 + B lymphocytes (7.41% [1.18%, 15.70%] vs. 3.55% [0.38%, 8.74%]) than the non-relapse group ( P<0.05). Positive correlations were noted between RTX administration intervals and NMOSD relapse and between CD3 -D19 +B lymphocytes and NMOSD relapse ( r=0.363, P<0.001; r=0.218, P=0.004); negative correlation was noted between CD3 -CD56 + NK lymphocytes and NMOSD relapse ( r=-0.193, P=0.011). Conclusion:Extended RTX administration interval can increase NMOSD relapse; CD3 -CD56 + natural killer lymphocytes and CD19 +B lymphocytes may regulate the disease states of NMOSD patients.
