Objective To analyze the genomic structure of a novel RHD allele. Methods Through polymerase chain reaction (PCR), sequence specific primer-PCR(SSP-PCR) and genomic DNA sequencing,the RHD gene in a D-negative individual was detected. Results In SSP-PCR tests, the sample was tested negative for exons 3~7, 9~10 and intron 2(Din 2), but was positive for the Rh downstream Box3. The RHCE genotype was Ccee. Three PCR methods were used to detect intron 10(Din10) of RHD gene;all gave negative results. Through a RHD full length coding region sequencing method, the sample was found to have sequences identical to normal RHD in exons 1 and 2, while exons 3~10 were negative. Conclusion The sample is D antigen negative, RHD gene positive, with amalgamative allele of RHD-CE(2~10).

ObjectiveTo evaluate two "up and down stair" methods used by hemiplegic patients.Methods40 cases with hemiplegia were randomly divided into two groups with 20 cases in each group. Patients in the group A went upstairs with health leg and downstairs with affected leg, while, patients in the group B upstairs with affected leg, downstairs with health leg, and then up and down stairs with health and affected leg alternated. Effects of two training menthods were compared.ResultsEach of two training methods had its advantage and disadvantage, but motor function and mobile ability of patients in the group B were better than patients in the group A (P<0.05).ConclusionHemiplegic patients Should choose different training method of up and down stairs according to his status, and not always choose the method of going upstairs with health leg and downstairs with affected leg.

Objective To compare the effect between computer assisted navigation total knee replacement and conventional total knee replacement on rotation alignment,mechanical axes,comPOnent position and clinical outcomes.Methods Eighty-two patients were recruited into this pmspoctive study according to entry criteria and were randomly selected into either control group which treated with standard knee replacements or navigation assisted group which operated with navigation assisted total knee replacements.To analyze the rotation of the femoral component and the tibial component in the transverse plane.the combined rotation of both components and mismatch between two components,the mechanical axes,which were measured from postoperative radiographs and computed tomography images.To compare the functional outcomes at 6 weeks and 6 months.Results There were significant diffefences(P＜0.05)in following parameters between control group and navigation assisted group:average rotation of femoral component were 1.51°±3.55°in control group and-0.63°±3.04°in navigation assisted group,the combined rotation of both components were 2.85°±4.07°in control group and 0.28°±3.43°in navigation assisted group,mismatch between components were 1.44°±4.55°in conlrol group and-0.43°±2.86°in navigation assisted group.There were no significant differences between two groups in rotation of tibial component.In addition,analysis showed that patients in navigation assisted group had significantly better mechanical axes and functional outcomes at 6 weeks.Conclusion The use of navigation can help avoid malrotation and errors in axial rotation,and provides improved alignment accuracy as well as better functional outcomes at 6 weeks.

Objective To investigate the influence of evidence-based nursing intervention on treatment effect and quality of life in nephrotic syndrome children. Methods 98 cases were randomly divided into the intervention group and the control group. The control group received routine nursing and the intervention group additionally received evidence-based nursing intervention. We compared the average hospital stay, treatment effect and quality of life in two groups. Results The average hospital stay in the intervention group was shorter than that of the control group. The treatment effect in the intervention group was ameliorated than that of the control group. The quality of life in the intervention group was ameliorated than that of the control group. Conclusions Evidence-based nursing intervention could obviously improve the treatment effect and quality of life in children with nephrotic syndrome.

Objective Study on fetomaternal immuno state and RHD type of a pregnant woman of weak D phenotype.MethodsThrough polymerase chain reaction (PCR)、direct genomic DNA sequencing and flow cytometry.ResultsIn both sequence specific promer (SSP) PCR and the sequencing PCR tests, the sample was detected negative in exons 3 6 of the RHD gene, whereas all other exons (exons 1 2,7 10) were tested positive. And the sequence of detected exons (exons 1 2,7 10) are the same with normal RHD in GenBank (accession no. AJ299020 1 and AJ299026 9). Serologically and genetically, the sample can be designated as D category VI type Ⅲ. Through a duce tube PCR method, the RhD zygosity of this individual was typed CD VI e/cde。In flow cytometry, a few fetal erythrocytes were detected in peripheral blood of the mother. However there were no anti D detected in sera and hemolytic disease of the newborn(HDN) observed at all.ConclusionSevere cases of HDN have occurred in D positive babies born to partial D mother with anti D, although HDN don't take place in this case. We may still consider D VI phenotype individuals as D positive donors and D negative receiptions in our transfusion practice and in clinical anti D allo immune prophylaxis and monitoring.
