Objective To explore the polymorphism and distribution of apolipoprotein E(ApoE)gene in patients with hyperlipidemia.Methods A total of 370 hyperlipidemia patients diagnosed at Hangzhou Ninth People's Hospital from October 2023 to June 2024 were selected.Gene polymorphism was detected in the blood samples of the patients using fluorescence polymerase chain reaction,and the distribution of gene polymorphism among different genders and age groups within this population was compared.Results ①The polymorphism distribution of the two genetic loci(ApoE 388T＞C and ApoE 526C＞T)in the studied sample population conforms to Hardy-Weinberg equilibrium,indicating that it is representative of the population;②Among the 370 patients,the distribution of the ApoE gene was as follows:E3/E3(66.49％),E3/E4(20.27％),E2/E3(8.65％),E2/E4(1.89％),E2/E2(1.35％),and E4/E4(1.35％).The proportion of the patient population carrying the E4 allele was about 1.88 times higher than that of those carrying the E2 allele;③The distribution differences of ApoE gene polymorphism were not related to the patients'gender and age(P＞0.05).Conclusion The distribution of ApoE gene polymorphism among hyperlipidemia patients at a hospital in Hangzhou is uneven and is not related to gender or age groups.Therefore,it is recommended to prioritize the detection of ApoE gene in patients before using statin medications to assess treatment effectiveness.

Objective To investigate the value of receiver operating curve human papilloma virus(HPV)-DNA typing combined with serum neutrophil lymphocyte ratio(NLR)and bicorticoid kinase 1(DCLK1)levels in the early diagnosis of cervical cancer.Methods A total of 120 patients with early cervical cancer diagnosed in our obstetrics and gynecology department from August 2018 to June 2022 were randomly included as cervical cancer group,and 120 patients with benign lesions were included as benign group.The level of DCLK1 was detected by ELISA;NLR was detected by automatic blood cell analyzer;HPV subtypes in cervical secretions were detected by HPV genotyping gene chip detection system;the cut-off values of serum NLR and DCLK1 levels in the diagnosis of cervical cancer were analyzed by using the receiver operator curve(ROC);four table method was applied to analyze the diagnostic value of HPV-DNA typing,serum NLR,DCLK1 levels alone and in combination for cervical cancer.Results Compared with benign group,the levels of serum NLR and DCLK1 in cervical cancer group were obviously higher(P<0.05).The positive rate of HR-HPV in cervical cancer group was obviously higher than that in benign group(P<0.05).The ROC curve was drawn with serum NLR and DCLK1 levels as test variables,the results showed that the AUC of serum NLR and DCLK1 predicting early cervical cancer was 0.724 and 0.718,respectively,and the cut-off value was 3.08 and 3.32,respectively.HPV-DNA typing combined with serum NLR and DCLK1 detected 18 false positives and 17 false negatives,Kappa value was 0.725,which was consistent with pathological results.The sensitivity,negative predictive value and accuracy of HPV-DNA typing combined with serum NLR and DCLK1 levels in the diagnosis of early cervical cancer were obviously higher than those of HPV-DNA typing,serum NLR and DCLK1 levels alone(P<0.05).Conclusion The results of HPV-DNA typing combined with NLR and DCLK1 in the diagnosis of early cervical cancer are highly consistent with the pathological results,and the sensitivity and accuracy are obviously improved.
