Methods From March 2017 to January 2022, cervical cytological specimens of 585 patients with ASC-US diagnosed by liquid based thinprep cytology test (TCT) were collected. p16 protein was detected by immunocytochemistry, HPV DNA genotype was detected by biochip and the patients underwent colposcopy pathological biopsy within 8 weeks. Taking the histological diagnosis results as the gold standard, the differences of the positive rate of p16 immunocytochemistry and HPV DNA genotyping in the same level of cervical lesions, differences of the positive rate of the same detection method in different levels of cervical lesions and differenes of p16 immunocytochemistry HPV DNA genotyping alone and combined detection of the diagnostic efficacy of lesions severer than high-grade squamous intraepithelial lesion (HSIL) were compared to comprehensively evaluate an optimal ASC-US shunt method. Results ①The positive rate of combined detection of (p16+HPV DNA) in the same level of cervical lesions was higher than that of differences of p16 immunocytochemistry and HPV DNA genotyping. ②The positive rate of combined detection of (p16+HPV DNA), p16 immunocytochemistry and HPV DNA genotyping increased with the aggravation of cervical lesions. ③The combined detection of (p16+HPV DNA) had the best comprehensive diagnostic efficiency and its sensitivity, specificity, coincidence rate and Yoden index were 99.07%, 62.55%, 69.23% and 0.62 respectively. Conclusions p16 immunocytochemical assay and HPV DNA genotyping, both alone and in combination, contributed to ASC-US shunt. However, the combined detection of (p16+HPV DNA) had better sensitivity and Yoden index, with high specificity and coincidence rate, which can effectively carry out ASC-US shunt.

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.

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.

目的 儿童流感相关坏死性脑病(influenza-associated necrotizing encephalopathy,IANE)是一种严重的流感并发症,目前缺乏早期诊断预警指标,本文探讨血生化和脑脊液检测在儿童IANE早期预警中的作用,为IANE早期诊断提供预测参考。 方法 回顾分析2016年1月—2020年12月在我院接受诊治的确诊流感并发神经系统并发症的患儿。40例流感相关性脑病(influenza-associated encephalopathy,IAE)和32例IANE患儿纳入研究。采用受试者工作特征曲线(ROC)分析来确定所选变量的预警价值。 结果 与IAE组相比,IANE组丙氨酸转氨酶(ALT)、天冬氨酸转氨酶(AST)、肌酐激酶(CK)、乳酸脱氢酶(LDH)、脑脊液乳酸脱氢酶(CSF LDH)、脑脊液蛋白(CSF PRO)均升高,两组差别有统计学意义(P<0.05)。用于区分IAE和IANE的LDH、CSF LDH和CSF PRO的曲线下面积(AUC)分别为0.876、0.853和0.831。LDH>535 U/L预测IANE的敏感度为89.7%,特异度为86.5%。CSF LDH>67 U/L预测IANE的敏感度为82.8%,特异度为73.3%。CSF PRO>0.49 g/L预测IANE的敏感度为73.7%,特异度为76.6%。IANE患儿死亡10例(43.3%),IAE患儿死亡0例(P<0.05)。 结论 IANE组LDH、CSF LDH和CSF PRO明显升高,可作为IANE的早期预警指标。对此类患儿要密切评估,早期预测及干预,减少后遗症及病死率,改善预后。

Objective Influenza-associated necrotizing encephalopathy (IANE) in children is a serious complication of influenza. At present, there is a lack of indicators for early diagnosis and early warning. In this paper, the role of blood biochemical and cerebrospinal fluid detection in early warning of IANE in children is discussed, so as to provide a predictive reference for early diagnosis of IANE. Methods A retrospective analysis was conducted on children diagnosed with influenza and with neurological complications who were treated in our hospital from January 2016 to December 2020. Forty children with influenza-associated encephalopathy (IAE) and 32 children with IANE were included. Receiver operating characteristic curve (ROC) analysis was used to determine the predictive value of the selected variables. Results Compared with IAE group, the levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), creatinine kinase (CK), lactate dehydrogenase (LDH), cerebrospinal fluid lactate dehydrogenase (CSF LDH) and cerebrospinal fluid protein (CSF PRO) were all increased in IANE group, and the differences between the two groups were statistically significant (P<0.05). The area under curve (AUC) of LDH, CSF LDH and CSF PRO used to distinguish IAE from IANE were 0.876, 0.853 and 0.831, respectively. The sensitivity and specificity of LDH>535 U/L for predicting IANE were 89.7% and 86.5% respectively. The sensitivity and specificity of CSF LDH>67 U/L for predicting IANE were 82.8% and 73.3% respectively. The sensitivity and specificity of CSF PRO＞0.49 g/L in predicting IANE were 73.7% and 76.6%. There were 10 deaths of IANE (43.3%) and 0 death of IAE (P<0.05). Conclusion The levels of LDH, CSF LDH and CSF PRO were significantly increased in IANE group, which could be used as early warning indicators for IANE. For such children, close evaluation, early prediction and intervention should be made to reduce sequelae and fatality rate and to improve prognosis.

Objective To detect the expression of peripheral blood circulating tumor cells CTC in patients with primary liver cancer and to explore the dynamic changes of CTC and its predictive effect on postoperative recurrence and metastasis of primary cancer. Methods The number of CTC in peripheral blood was measured in 134 patients with primary liver cancer and 72 patients with benign liver disease, the expression of AFP was detected, and the correlation between CTC and AFP was analyzed. Then 86 patients with primary liver cancer were selected from 134 patients with primary liver cancer who underwent radical hepatectomy. The values of CTC and AFP in evaluating recurrence and metastasis of primary liver cancer before and after operation were analyzed by CTC and AFP, in peripheral blood of these 86 patients. Results The positive rates of CTC in peripheral blood of patients with primary liver cancer were higher than that of patients with benign liver disease(P< 0.05). The levels of CTC in patients with primary liver cancer were related to AFP level, lymph node metastasis and the number of tumor nodules, but not to age, sex, tumor diameter, differentiation degree, liver cirrhosis and TNM stage. The survival analysis of CTC and AFP in patients with primary liver cancer showed that the early recurrence and metastasis of primary liver cancer after radical resection were closely related to the positive rate of CTC and AFP, and the positive rate of CTC was more effective than that of AFP positive in the diagnosis of recurrence and metastasis after operation, and the combination of the two had the highest predictive value for recurrence and metastasis. Conclusion CTC may be used as a better index to monitor postoperative recurrence and metastasis of primary liver cancer than traditional tumor markers. The combined detection prediction value of tumor markers is higher.

目的 研究在新型冠状病毒COVID-19疫情期间,政府采取的干预措施对医院检测的流行性感冒(简称流感)阳性率的影响,为制定流感预防措施提供依据,也为间接评价新型冠状病毒的预防效果提供参考。方法 回顾性收集广州市第一人民医院总院2018—2020年年廿三至正月十五期间的流感抗原检测数据,对政府干预前后的流感抗原检测阳性率进行分析比较。结果 在春节前后,2018年和2019年的流感检测阳性率总体上维持稳定。其中,2018年春节前后,流感阳性率在15.6%～46.5%范围内波动,2019年春节前后,流感阳性率在11.9%～30.4%范围内波动。2020年同期的流感阳性率变化曲线与前两年不同,在正月初四前曲线变化较为稳定,维持在20.0%～44.1%范围内。在正月初四后曲线呈现显著下降趋势,在正月十二和正月十五,流感检测阳性率变为0。进一步的分析表明,政府干预对流感阳性率的影响无性别差异,对5～64岁人群效果最佳。结论 当前针对新型冠状病毒COVID-19的政府干预措施能显著降低流感阳性率,预防流感的发生,也为预防同样以呼吸道传播为主的新型冠状病毒的传播提供了间接证据。

Objective The aim of the study was to study the effect of government interventions on the positive rate of influenza detected in Guangzhou First People's Hospital during the outbreak of COVID-19, and to provide a basis to develop prevention measures against influenza and a reference for the indirect evaluation of the preventive effect of COVID-19. Methods Influenza antigen detection data of Guangzhou First People's Hospital were collected retrospectively from 23rd of the 12th lunar month to 15th of the 1st lunar month in 2018—2020, and the positive rates of influenza antigen detection before and after the government intervention were analyzed and compared. Results The positive rates of influenza were generally stable in 2018 and 2019 before and after the Spring Festival, where the positive rate fluctuated in the range of 15.6%～46.5% in 2018, and the positive rate fluctuates in the range of 11.9%～30.4% in 2019. The temporal change of the positive rate in 2020 was different from that of the previous two years. The positive rate curve was relatively stable before the fourth day of the first lunar month, maintaining a range of 20.0%～44.1% in 2020. After the fourth day of the first lunar month, the curve showed a significant downward trend. On the 12th and 15th day of the first lunar month, the positive rate of influenza became 0. Furthermore, the effect of government intervention on the positive rate of influenza showed no gender difference, and the effect was significant for people aged 5～64 years. Conclusion The current government intervention measures against COVID-19 could significantly reduce the positive rate of influenza, prevent the occurrence of influenza, and provide indirect evidence for the prevention of the spread of COVID-19, which was also mainly spread by respiratory tract.
