Objective Through blood analysis and C-reactive protein (CRP) level detection, to explore its value in the auxiliary diagnosis of influenza A and B in children, and to provide reference for clinical treatment. Methods 3 069 children with influenza A, 2 307 children with influenza B, and 855 healthy children were selected, and blood routine parameters and CRP levels were statistically analyzed. The ROC curve was used to analyze the discriminatory efficacy of blood routine on influenza A and B. Results The mean value of white blood cell count (WBC) in group A was higher than that in normal group, but in group B it had the opposite result. The percentage of neutrophils (Neut%), the ratio of neutrophils to lymphocytes (NLR), and the percentage of monocytes (the mean value of Mono%) is higher than that of normal group, and the mean value of lymphocyte percentage (Lymph%) and platelet count (PLT) of group A and B is lower than that of normal group. The mean values of neutrophil count (Neut#), monocyte count (Mono#), CRP and PLT in group A were higher than those in group B, and the mean values of Lymph% and lymphocyte count (Lymph#) were lower than those in group B. The composition ratios of group A in WBC>13×10⁹/L, Neut%>70.7, Lymph%<19.1 were higher than that in group B. The NLR predicted the critical value of influenza A was 2.08 (sensitivity 75.9%, specificity 89.4%), and the predicted influenza B threshold value was 2.11 (sensitivity 50.5%, specificity 89.8%). Conclusion Changes in blood routine parameters and CRP levels can be used to determine whether there is a bacterial infection in children with influenza and to guide clinical medication; NLR as a new predictive marker, its changes can distinguish influenza A or B. Especially in influenza A determination, it has clinical value.

Objective To investigate the clinical value of p16/Ki-67 staining E6/E7 mRNA and combined detection in the diagnosis of HSIL+ lesions. Methods From March 2017 to August 2020,209 cases of cervicitis,169 cases of LSIL,131 cases of HSIL and 86 cases of cervical cancer confirmed by histology were selected as the research objects. The results of p16/Ki-67 staining and HPV E6/E7 RNA detection of the preoperative cytological samples were retrospectively analyzed and the p16/Ki-67 staining and HPV E6/E7 mRNA detection results were compared longitudinally. The positive rates of E6/E7mRNA and combined detection in different grades of cervical lesions were compared.The positive rates of p16/Ki-67 staining,HPV E6/E7 mRNA and combined detection in the same cervical lesions were compared horizontally.The differences in the diagnostic efficacy of p16/Ki-67 staining,HPV E6/E7 mRNA and combined detection in the diagnosis of HSIL+lesions were comprehensively evaluated. Results ①Longitudinal comparison:the positive rates of p16/ Ki-67 staining, HPV E6/E7mRNA and combined detection increased with the severity of cervical lesions(p16/Ki-67 staining:χ²=374.34,P<0.001;HPV E6/E7 mRNA detection:χ²=289.21,P<0.001;joint detection:χ²=343.90,P<0.001). ②Transverse comparison: in cervicitis, LSIL and cervical cancer groups,there were no significant differences in the positive rates of p16/Ki-67 staining, HPV E6/E7 mRNA and combined detection (all P>0.05). In the HSIL group,there was significant difference in the positive rate between p16/Ki-67 staining and combined detection (χ²=8.09,P=0.004)and the difference between HPV E6/ E7 mRNA and combined detection was statistically significant(χ²=11.30,P=0.001). ③The sensitivity of p16/Ki-67staining,HPV E6/E7 mRNA and combined detection in the diagnosis of HSIL+ was statistically significant(χ²=7.69,P=0.021). The sensitivity difference between p16/Ki-67 staining and combined detection was statistically significant(χ²=7.29,P=0.007);the sensitivity difference between HPV E6/E7 mRNA detection and combined detection method was statistically significant (χ²=4.84,P=0.028). There was no significant difference in the specificity and coincidence rate of p16/Ki-67 staining,HPV E6/E7 mRNA and combined detection in the diagnosis of HSIL+(χ²₁=5.38,P₁=0.068;χ²₂=0.93,P₂=0.628). Conclusion P16/Ki-67 staining,HPV E6/E7 mRNA and combined detection may effectively screen out HSIL+ lesions,reduce the missed diagnosis rate, but the combined detection may significantly improve the sensitivity of diagnosis of HSIL+ lesions, while maintaining good specificity and coincidence rate.It is suggested that p16/Ki-67 staining and HPV E6/E7 mRNA detection should be used as a strategy for early diagnosis of HSIL+ lesions.

Objective To analyze the results of nonrepetitive reactivity of HBV nucleic acid detection in blood donors. Methods 1 200 blood samples from our station were confirmed by nonrepetitive reaction, supplemented with the “two to half” test of hepatitis B, and some patients with single nucleic acid detection were followed up. Results One hundred and fifty samples (12.50%) were reactive in single nucleic acid detection in 1 200 blood samples. After the virus nucleic acid detection, 58 samples were reactive (38.67%), 92 were nonreactive (61.33%). 18 donors were actually recalled and drew blood, completed two tracking. The first tracking time was 60-125 days, the second time interval was 160-356 days. In the first tracking 8 cases had HBV DNA reaction (+) , which still had reaction in the second tracking; 7 HBV DNA positive donors had HBC antibody (+).The proportion of HBV-DNA positive with 10-17 value in mucleic acid reaction test(37.25%) was higher than that with value below 10(4.17%,P＜0.05). Conclusion Some donors with single nucleic acid detection reaction have a certain risk of transmission of HBV, most of them had hidden infection of HBV. At this time, we should pay attention to the blood transfusion and avoid the single nucleic acid reactive donors.
