ABSTRACT
Objective To investigate the application effect of the Beckman Coulter PK 7300 automatic blood group analyzer and the microplate method in ABO blood group screening .Methods A total of 12000 EDTA anticoagulation whole blood samples from January to May 2015 were collected from voluntary blood donors .The Beckman Coulter Pk7300 automatic blood group analyzer and STAR sampling microplate manual colorimetric method were to conduct the detection analysis .Results The accuracy for detecting ABO blood group had no statistically significant difference between the two methods (P>0 .05) .In the ABO blood group screening , the detection rates of ABO subtype and antibody weakening in the Beckman Coulter Pk 7300 automatic blood group analyzer were higher than those in the micro plate method .3 cases of ABO blood group typing and reverse typing were consistent in the detection by the Beckman Coulter Pk7300 automatic blood group analyzer ,but was inconsistent in the detection by the microplate method .4 cases of ABO blood group typing and reverse typing were inconsistent in the the detection by the Beckman Coulter Pk 7300 automat-ic blood group analyzer ,but was consistent in the detection by the microplate method .Conclusion The Beckman Coulter Pk7300 automatic blood group analyzer can safely and effectively conduct the ABO blood group screening in blood donors .The samples of suspicious detection results still need to conduct the manual interpretation by combining with the test tube method .
ABSTRACT
Objective:To investigate the change of apoptosis-associated genes in human lung adenocarcinoma cell lines A549/DDP cells,which were induced by the recombinant human interleukin-24(rhIL-24) combined with Cisplatin (DDP). Methods: Six genes expression level by GeXP genetic analysis system at the same time,after rhIL-24,DDP and rhIL-24+DDP were used to intervene in A549/DDP cells. Results:rhIL-24 could induce Bax gene,Caspase3 gene and Rb gene transcription up regulation;Bcl-2 gene and survivin gene transcription down regulation. But no regular change in the genes expression level of P53. Bax,Survivin and Rb were more obviously changed after rhIL-24 combined with DDP. Conclusion: RhIL-24 can induce apoptosis of A549/DDP cells through upregulated the genes expression level of Bax,Caspase3,Rb and down regulated of Bcl-2,Survivin.
ABSTRACT
Objective:To elucidate the characterization of CD8+T cell in H1N1 influenza vaccine for children.Methods:PBMCs were isolated from 31 children aged from 3 to 6 years old who had accepted H 1N1 influenza vaccine during December 2009 to January 2010.The lymphocytes were joined with the H 1N1 influenza vaccine as experimental group and cultured .The experiment set without vaccine group as control group .At last we detected the surface molecules by FCM .The CCK-8 assay was added to detecting cellular proliferation and cellular proliferation index were detected by CCK-8.Results: CD8+T cells of PBMC in the two groups were 13.41%and 9.41%,P>0.05.CD8+CD45RAA+naive T cells in the two groups were up to more than 80%,P>0.05.The proportion of CD8+CD45ROA+memory T cells in two groups were up to 17%-19%,P>0.05.Two subsets of CD8+CD45ROA+memory T cells :CCR7+and CD62L+single positive memory T cell subsets in the experimental group were significantly lower than that of the control group,P<0.05.The CCK-8 assay was added to detect cellular proliferation .Only 51.16% of which cellular proliferation index was greater than 0.8,with none was greater than 1 in this study.Conclusion:This study showed that the CD4+T cells were low-level,naive T cells (CD8+CD45RAA+)were higher,with antigen stimulation and response.H1N1 vaccination specific memory T cells were few in number , specific memory T cell subsets were diversity , control memory cells were the main phenotypic characteristics .Cellular proliferation index showed that the proliferation of specific CD 8+T cells vaccine was poor .
ABSTRACT
Objective To analysis the human cytomegalovirus (HCMV)and human T lymphotropic virus(HTLV)infection status in Beijing among voluntary blood donors.Methods Randomly selected 2 010 blood samples from five districts and counties of Beijing City to screen HCMV-IgG,HCMV-IgM and HTLV-Ⅰ/Ⅱ antibody by ELISA method.The positive samples were reexamined two times,two test results of samples were positive that were determined positive by ELISA. HTLV positive samples was confirmed by nested PCR.Results The HCMV-IgM and HCMV-IgG positive rates of Beijing blood donors were 2.19% and 92.59%,screened 1 case of anti-HTLV positive by ELISA method,then confirmed to be neg-ative result by nested PCR.The statistics showed that the HCMV-IgG positive rate female blood donors was higher than male (P 0.05).Conclusion In this investigation,2 010 cases of voluntary blood donors from five districts of Beijing were not found in cases of HTLV infection,HCMV infection was prevalent.
ABSTRACT
As one of the important factors that impact the life of quality to the elderly,visual impairment has become a research highlight in developed countries.And some related results have been found out.It is in the primary stage of establishing the elderly community extending service system in China.Based on this background,literature about the impact of visual impairment on quality of life of the residential setting elderly and related interventions were reviewed.By drawing the experience from developed countries,we aim to innovate perfect interventions,improve the quality of life,avoid unexpected events such as fall and medication mistakes.
ABSTRACT
With the public hospitals expanding,the nurses at age of marriage or bearing are enrolled and account for large part of all health care workers in China.A significant percentage of nurses in the period of pregnancy or lactation,especially abortion and sterility,deteriorate the shortage of nursing human resources and the nurses' health.It is essential to cope with the matter in order to maintain the nurses and contribute to the professional development.In this paper,we review the human resource management of the nurses during the periods at home and abroad from the human resources,occupational protection and management approaches,which is contributed to supplement the human resource.
ABSTRACT
OBJECTIVE To investigate the relationship between the Nco I, Ava II polymorphism of low density lipoprotein receptor (LDL-R) gene in patients with the occurrence of atherosclerotic cerebral infarction (ACI) among the Han nationality in Liaoning province. METHODS The polymerase chain reaction technique was used to study the polymorphisms of LDL-R gene and allele frequencies in 77 patients with ACI and in 113 age-matched Chinese healthy controls. The levels of the lipid and lipoproteins were also compared among the cases with ACI and the controls. RESULTS A(+) frequencies of LDL-R gene in healthy controls and ACI group were 0.230 and 0.125 respectively, while the N(+) frequencies of healthy control and ACI group was 0.667 and 0.662 respectively. In case of the coexistence of A(-) A(-) and N(+) N(+), the relative risk (RR) of ACI was 5.56(P<0.001), while the RR of the increase of serum levels TG, TC, LDL-C, LP(a) were 4.29, 7.67, 9.33 and 3.09(P<0.05), respectively. CONCLUSION The coexistence of A(-) A(-) and N(+) N(+) can affect the concentration of lipid and lipoprotein and is in close relationship with the occurrence of ACI.

Objective To determine the relationship between angiotensin converting enzyme gene polymorphism and ? myosin heavy chain gene and dilated cardiomyopathy (DCM) among people of Han nationality in Liaoning province. Methods The insertion/deletion (I/D) polymorphism of ACE gene was detected by the polymerase chain reaction (PCR) in 43 patients with DCM and 53 normal controls. The exons 13,14 of cardiac ?-MHC gene from 43 patients and 53 controls were amplified restrictively by using PCR. The amplified products of PCR were digested by restrictive en-donuclease DdeⅠ and NlaⅢ to identify the mutations at No. 8848 and 9124 nucleotide of ?-MHC gene. Results The frequency of ACE DD genotype and the frequency of the allele D was remarkably higher in individuals with DCM than those in normal control people ( P
