Objective To discuss the significance of the application of neutrophil to lymphocyte ratio (NLR)combined with prostate specific antigen (PSA)in early diagnosis of prostate carcinoma.Methods 120 cases with surgery treatment of prostate carcinoma were selected as study group,and 120 healthy people were selected as control groups.The NLR and PSA were tested to diagnose the prostate carcinoma.The critical value of NLR in diagnosing prostate carcinoma was evaluated by ROC curves,and the advantages of combination of NLR and PSA were judged. Results By using ROC curves to evaluate the NLR in diagnosis,the critical value was 2.75.The susceptibility, specificity,Youden index,correct index were 0.79,0.85,0.65,0.72.The susceptibility,specificity,positive predictive value,negative predictive value,correct index of NLR combined with PSA in diagnosing the prostate carcinoma were 0.85,0.83,5.00,0.18,0.68.Conclusion The application of NLR has higher susceptibility and specificity to diagnose prostate carcinoma.NLR combined with PSA can improve the susceptibility and specificity of early diagnosis of prostate carcinoma.

Objective To evaluate the correlation of the single nucleotide polymorphisms (SNPs) in CDH13 with non-small cell lung cancer (NSCLC) . Methods 115 patients with NSCLC and 110 healthy controls were included in present study. Two SNPs (rs11646213 and rs7195409) in CDH13 were genotyped using TaqMan method. The association of these two SNPs with NSCLC was calculated and assessed. Results The genotypic and allelic frequencies of rs11646213 showed significant difference between NSCLC patients and the control group (P<0.05), (OR=0.464, 95% CI:0.273~0.789) . The genotypic and allelic frequencies of rs7195409 showed significant difference between the stage I+II and stage III+IV groups (P<0.05), (OR=0.491, 95% CI:0.243~0.991) . Conclusions The rs16146213 has a strong association with NSCLC and G allelic showed a protective effect. The rs7195409 has a strong association between stage I+II and III+IV in NSCLC, and G allele may play a protective role in the development of NSCLC.

【Objective】 To explore the psychological experience of blood donors with blood donation-related vasovagal reaction (DRVR), so as to provide basis for improving the quality of blood donation services. 【Methods】 The real experience of 9 DRVR blood donors was analyzed using the phenomenological research method in qualitative research. 【Results】 The occurrence of DRVR caused distinct psychological conflict among blood donor. Blood donors lacked knowledge about blood donation and expected professional evaluation and continuous support. The occurrence of DRVR was an important reason for blood donor lapsing. 【Conclusion】 By resolving the distinct psychological conflicts of DRVR blood donors, establishing DRVR early warning evaluation and feedback system, as well as strengthening the construction of support system, blood collection and supply institutions can create a good humanistic and social environment for sustainable development of voluntary blood donation.

【Objective】 To study the annual financial expenditure in blood stations with different scales, and to establish the regression equation between blood collection units and total expenditure. 【Methods】 The annual total expenditure, the per capita cost of serving population, as well as the collection units of whole blood and apheresis platelet of 24 blood stations were collected. The financial expenditure required for collecting 10 000U blood was calculated.The statistical analysis was carried out with SPSS statistical software. 【Results】 From 2017 to 2020, the total annual financial expenditure of 24 blood stations showed an upward trend. The total expenditure among blood stations was different. The per capita cost of servicing population in the areas where the 24 blood stations were located had been increasing year by year. The 24 blood stations were divided into two grades according to the blood collection volume as 50 000 U, and the relationship equation between the blood collection volume and the annual total expenditure had been established. After testing, each equation was effective(P<0.05); There was no difference in the financial expenditure required for collecting 10 000U blood among blood stations with different scales. 【Conclusion】 From 2017 to 2020, the blood stations with an annual collection volume more than 50 000 U demonstrated a higher financial expenditure and the per capita cost of serving population than those <50 000 U. The blood collection volume of blood stations is significantly correlated with the annual total expenditure and the per capita cost of serving population.
