ABSTRACT
Objective To develop an auxiliary recovering device for prone position nursing after the retina vitrectomy in order to improve comfort and treatment compliance.Methods The device was made of stainless steel,and consisted of a base,pulleys,supporting rods and a placing case.Totally 40 patients receiving retinal detachment operation were divided into an experimental group and a control group.The patients in the experimental group applied the auxiliary device and the ones in the control group underwent conventional nursing,and then a 2-week observation was executed on the prone time,overall satisfaction and adverse response after the operation.Results The device behaved well in prone time,patient comfort and satisfaction,and the experimental group gained advantages over the control group in prone time,relieving muscle pains,arthralgia,poor breath,anxiety and insomnia.Chi-square test proved the experimental group had the patient satisfaction significantly enhanced when compared with the control group (P＜0.05).Conclusion The device can be used for auxiliary nursing after retinal detachment operation with simple structure,easy operation and high comfort,and thus is worthy promoting practically.
ABSTRACT
<p><b>OBJECTIVE</b>To explore the molecular basis for a CD36 deficiency individual and distribution of CD36 gene mutation in Guangxi population.</p><p><b>METHODS</b>A female individual was studied. CD36 phenotype was detected by monoclonal antibody immobilization of platelet antigens assay (MAIPA) and flow cytometry (FCM). The coding regions of the CD36 gene were sequenced. A DNA-based polymerase chain reaction-sequence specific primer (PCR-SSP) assay was used to verify the identified mutation. Cell lines expressing the mutant and wild-type CD36[CD36(MT) and CD36(WT)] were established, with the expression of CD36 determined by Western blotting. The distribution of CD36 gene mutation was investigated among 1010 unrelated individuals with the PCR-SSP assay.</p><p><b>RESULTS</b>Both MAIPA and FCM assays showed that the patient had type II CD36 deficiency. DNA sequencing showed that she has carried a heterozygous mutation T538C (Trp180Arg) in the exon 6 of CD36. Sequencing of cDNA clone confirmed that there was a nucleotide substitution at position 538 (538T>C). Western blotting also confirmed that the CD36 did not express on the CD36(MT) cell line that expressed the 538C mutant, but did express on the CD36(WT) cell line. The novel CD36 mutation T538C was further verified with 100% concordance of genotyping results by DNA-based PCR-SSP assay and 1010 unrelated individuals. No CD36 538C allele was detected among the 1010 individuals.</p><p><b>CONCLUSION</b>This study has identified a novel CD36 mutation T538C(Trp180Arg)(GenBank: HM217022.1), and established a genotyping method for the novel sequence-specific primer PCR. The novel mutation is rare in Guangxi and can cause type II CD36 deficiency.</p>

Objective To establish the platelet antigen panel cells and to apply them in the detection and identification of platelet alloantibody.Methods Human platelet antigen(HPA)1-16 genotyping from 1 500 un-related blood donors in Nanning area were performed by the polymerase chain reaction-sequence specific primers(PCR-SSP)technique,platelet antigen cells with O blood type were chosen to establish the panel cells of platelet antigen.The phenotype of the panel cells were verified by the reference sera from the 14th platelet immunology workshop of the International Society of Blood Transfusion(ISBT).And then these panel cells were used in clinic to detect the platelet alloantibody and the samples from the 14th and 15th platelet immunology workshop of ISBT.Re-sults Six platelet cells with consistent phenotype and genotypes and covering the HPA 1-5 and 1 5 systems were selected to estab-lish the platelet panel cells and successfully applied them in the clinical and scientific sample detection and identification.Conclusion Platelet antigen panel cells are established successfully,which provides the experimental basis for the diagnosis and research of platelet allogenic abnormal immunity diseases.
