The positive rates and intensities of cyclin G1 expression increased gradually with the grade of cervical lesions. High-risk HPV infection rates were higher in CIN and SCC than normal groups （P 〈 0.05 ）. There was a positive correlation between cyclin G1 expression and high-risk HPV infection detected with HC-Ⅱ （Kendall＇s tau-b =0. 316, 0. 269, 0. 352, and 0. 474 in CIN Ⅰ, CIN Ⅱ, CIN Ⅲ, and SCC, respectively, P 〈 0. 05 ）. Conclusions Cyclin G1 is overexpressed in CIN and SCC. Cyclin G1 may be a biomarker for detecting CIN and SCC. Cyclin G1 may play an important role in the oncogenesis of CIN and SCC by high-risk HPV infection.

Correlation analysis of human papillomavirus E6/E7 mRNA detection with diagnosis,prognosis and recurrence risk in patients with cervical epithelioma

BACKGROUND Cervical intraepithelial neoplasia(CIN)is an important precursor of cervical cancer.Early detection and treatment can reduce the incidence of cervical cancer.AIM To investigate the detection rate of human papillomavirus(HPV)E6/E7 mRNA in cervical tissue of patients with different types of epithelial cell neoplasia(CIN)and its relationship with CIN progression and diagnosis.METHODS One hundred women with HPV infection detected by cervical exfoliation cytology between January 2022 and January 2023 were retrospectively selected.These patients were graded CIN based on colposcopy and cervical pathology.The positive expression rates of HPV E6/E7 mRNA and HPV[polymerase chain reaction(PCR)-reverse dot crossing]were compared among all groups.Patients with HPV E6/E7 mRNA expression in the grade 1 CIN group were followed up for 1 yr.The relationship between atypical squamous epithelium and high malignant epithelial neoplasia was investigated by univariate and multivariate analysis.RESULTS The diagnostic sensitivity,specificity,and sensitivity of PCR-reverse point hybrid ization technology for secondary CIN were 70.41%,70.66%,and 0.714,respectively.Sensitivity and specificity for secondary CIN were 752%and 7853%,respectively,the area under the curve value was 0.789.Logistic Multifactorial model analysis revealed that the HPV positive rates and the HPV E6/E7 mRNA positive rates were independent risk factors of CIN grade I(P<0.05).In CIN grade I patients with positive for HPV E6/E7 mRNA,in its orientation to grade CIN patients,in its orientation to grade CIN patients,at 69.2%,compared with patients negative for HPV E6/E7 mRNA(30.8%),significant difference(P<0.05).CONCLUSION HPV E6/E7 mRNA and HPV(PCR-reverse dot hybrid)positive expression have a close relationship with CINgrade disease progression and is an independent risk factor for high-grade CIN lesions.

Clinical Observation of rhIL-2 Combined with Zhenqi Fuzheng and BaofuKang Suppository in the Treatment of Cervical Intraepithelial Neoplasia II with HPV Infection

Objective: To investigate the clinical effects of recombinant human interleukin-2 (rhIL-2) combined with Zhenqi Fuzheng and Baofukang on cervical intraepithelial neoplasia II (CINII) combined with human papilloma virus infection. Methods: There were 593 patients diagnosed with CINII with HPV infection, including 296 in the control group and 297 in the experimental group. The control group was given only Zhenqi Fuzheng oral and Baofukang suppository vaginal medicine. The experimental group was treated with rhIL-2 injection in addition to Zhenqi Fuzheng oral and Baofukang suppository vaginal medicine which is treated for 3 months. After 3 months, Thinprep cytologic test (TCT), human papilloma virus (HPV) quantitative examination and colposcopy biopsy were reviewed. Results: After 3 months of treatment, the negative conversion rate and total effective rate of HPV in the control group were 58.11% and 70.95% respectively, and the negative conversion rate and total effective rate of the experimental group were 79.46% and 90.57% respectively. There was significant difference between the two groups (p = 0.000). The curative rate of cervical lesions was significantly higher in the test group than in the control group, 89.56%, 68.91%, respectively. The statistical difference between the two groups is significant (p = 0.000). Conclusion: It has an essential clinical value that HPV infection patients and cervical intraepithelial neoplasia II associated with HPV infection patients are treated by rhIL-2 combined with Zhenqifuzheng and Baofukang, which is safe, effective, non-invasive, reusable advantages. However, the long-term efficacy and side effects need to be further studied.

Clinical significance of human papilloma virus infection in the cervical lesions

Cervical lesions have been regarded as the common and frequently occurring diseases in China.Recently,the morbidity and youth tendency of cervical cancer have gradually increased.Cervical cancer,related with human papilloma virus(HPV)infection,has been one of the severest diseases threatening health and life of women,and is an infectious disease.The universality of HPV infection in the reproductive tract should not be ignored.The well-known risk factors of HPV infection in cervical lesions consist of high-risk sexual behaviors,immunosuppression,age,contraceptive methods,the concurrent infection of other sexually transmitted diseases,etc.The variation of cervical lesions induced by HPV infection is involved in the continuous pathological process,including the subclinical,latent,and persistent infection of high risk(HR)-HPV,chronic cervicitis with abnormal results of cytological examination,cervical intraepithelial neoplasia(CIN),and cervical cancer.The outcome of patients with HPV infection is influenced by many factors,such as HPV subtype dominance,persistent HPV infection,HPV loading dose,and multiple HPV infection.Controlling HR-HPV persistent infection should be an important strategy for reducing cervical lesions.

High-risk human papilloma virus infection and cervical neoplasm in female inflammatory bowel disease patients:a cross-sectional study

Background and aim:This cross-sectional study investigated the prevalence and risk factors of high-risk human papilloma virus(HPV)infection,especially types 16 and 18,and cervical neoplasia in female Inflammatory bowel disease(IBD)patients.Methods:From July 2014 to January 2017,sexually active,female,Chinese IBD patients(21–60 years)and age-matched controls underwent cervical ThinPrep cytology testing(TCT)and high-risk HPV-DNA detection,and completed questionnaires about awareness of cervical cancer and HPV.Cervical dysplasia was categorized as cervical intraepithelial neoplasia(CIN)1,2 and 3.Results:Of 124 IBD patients(30 ulcerative colitis and 94 Crohn’s disease),17(13.7%)had high-risk HPV among whom 9(7.3%)had HPV 16/18 infection and 4(3.2%)had cervical CIN(3 CIN 3,1 CIN 1)by pathology.Among 372 controls,33(8.9%)had high-risk HPV and only 1(0.3%)had HPV 16 infection.Cervical TCT detected atypical squamous cells of unknown significance in one control;no control had CIN.The HPV 16/18 infection rate and CIN prevalence were significantly higher in IBD patients than controls(both P<0.001).The HPV-infection rate was higher in patients administered methotrexate[P=0.005,odds ratio(95%confidence interval)4.76(1.471–15.402)]or more than two immunosuppressants[P=0.013,odds ratio(95%confidence interval)3.64(1.255–10.562)].Thiopurine,steroid,infliximab and disease behavior/location were not associated with HPV infection.Only 29.3%of patients had undergone cervical-cancer screening.Awareness of HPV infection and HPVrelated cervical cancer was poor(28.2%).Conclusions:Female IBD patients are at increased risk of high-risk HPV infection and cervical neoplasia,which may be associated with immunosuppressants.Education and routine follow-up with HPV-DNA testing and TCT are recommended,especially in female Chinese IBD patients.

Epidemiological studies of women under age 30 infectedwith human papillomavirus

The aim of this paper was to investigate the prevalence of human papilloma virus(HPV)infection in women under 30 years old with cervical intraepithelial neoplasia(CIN)or cervical cancer,in order to provide a basis for cervical cancer prevention and treatment.We recruited 2052 female cases from the education system in Futian District,Shenzhen city,from April 2006 to April 2008,with age ranging from 22 to 60 years old.Second-generation hybrid capture test was done for detection of female genital tract HPV and cervical colposcopy for screening CIN or cervical cancer.The prevalence of HPV and cervical precancerous lesions or cervical cancer was evaluated in different age groups of women.The HPV positive rate was 247/2052(12.00%),and 35/2052(1.71%)of the cases were≥CIN I by pathological diagnosis.In the 22–29-year-old age group,there were 291 cases,including 39 HPV-positive cases(13.40%)and one case of pathological diagnosis≥CIN I(0.34%),and there were 1761 cases in the 30–60-year-old age group,including 208 HPV-positive cases(11.81%)and 34 cases of pathological diagnosis≥CIN I(1.93%).The HPV-positive rate of 22–29-year-old age group was higher than that of 30–60-year-old age group,but the difference was not significant(χ2=0.5967,P=0.4398);the CIN and cervical cancer detection rate of the former group was lower than that of the latter one,and the difference was not significant either(χ2=3.7519,P=0.0527).The cases in 30–60-year-old age group were divided intofive age sub-groups,and the HPV-positive rate of the 22–29-year-old age group was compared with the remaining groups,and it was found that the HPV-positive rate of the former group(13.40%)was lower than that of the 40–44-year-old age group(14.70%)but higher than that of the other four groups.Moreover,the difference in the HPV-positive rate between the 22–29-year age group and the 50–60-year-old age group(6.06%)was significant(χ2=5.545,P=0.018),but the difference between the 22–29-year-old age group and each of the other four groups was not significant(P>0.05).In addition,the CIN and cervical cancer detection rate of the 22–29-year-old age group(0.34%)was lower than that of the remainingfive groups,and the difference between the 22–29-year-old age group and the 35–39-year-old age group(2.26%),and between 22–29-year-old age group and 40–44-year-old age group(2.30%)was significant(χ2=4.446,P=0.0035;χ2=4.525,P=0.0363,respectively),but the difference between the 22–29-year-old age group and each of other three groups was not significant(P>0.05).Furthermore,80.00%(28/35)cases of pathological diagnosis≥CIN I and 90.91%(10/11)lesions of pathological diagnosis≥CIN II occurred at 35–49 years of age.For many young women below the age of 30 who were infected with high-risk HPV were one-off infections,so it was not appropriate to recommend HPV detection as cervical precancerous lesions or cancer screening program for women less than 30 years old.The prevention and treatment of cervical cancer should be focused on those women more than 35 years of age.

目的探讨武威市凉州区女性子宫颈人乳头瘤病毒(HPV)感染情况,对子宫颈发生病变与HPV感染行相关性分析。方法采用扩增的聚合酶链式反应(PCR)方法对2021年3月至2023年9月在甘肃省武威市凉州医院进行宫颈癌筛查的13000名妇女进行检查。检测出HPV感染患者有1200例,对其行阴道镜检查及阴道镜下子宫颈活检术。根据宫颈组织活检提示有无子宫颈病变的发生分为两组,分别为病变组(n=486)未病变组(n=714)。运用单因素分析其子宫颈病变发生的影响因素,并运用多因素logistic回归分析方法对单因素中P<0.05中的因素进行分析。结果单因素分析结果提示病变组在年龄、有无持续HPV的感染、子宫颈柱状上皮外移情况、性伴侣数和HPV感染类型上与非病变组具有显著差异,差异有统计学意义(P<0.05);多因素分析结果显示,年龄为<25岁或≥55岁(β=0.754,OR=2.126,95%CI:1.649~2.740)、持续HPV的感染(β=1.048,OR=2.853,95%CI:2.209~3.683)、子宫颈柱状上皮外移(β=0.625,OR=1.868,95%CI:1.453~2.401)、性伴侣数≥2名(β=0.625,OR=1.988,95%CI:1.546~2.556)和HPV感染类型为高危型(β=0.863,OR=2.371,95%CI:1.833~3.066)都是影响子宫颈病变发生的独立危险因素。结论HPV感染与子宫颈病变之间存在联系,且HPV16/HPV18型是子宫颈病变HPV感染的主要类型,倡导定期体检,根据不同女性实施针对性措施对降低女性子宫颈HPV感染发生病变,预防子宫颈癌具深远意义。

免疫因子在中老年感染高危型人乳头瘤病毒宫颈病变患者中的变化及其与宫颈上皮内瘤变分级的关系

目的探讨免疫因子在中老年感染高危型人乳头瘤病毒(HR-HPV)宫颈病变患者中的变化及其与宫颈上皮内瘤变(CIN)分级的关系。方法选取2020年9月至2022年9月江西省中西医结合医院收治的HR-HPV持续感染的126例不同宫颈病变患者作为研究对象,根据阴道镜下宫颈组织病理检查明确分为宫颈炎症组32例、CINⅠ组33例、CINⅡ组30例、CINⅢ组31例。检测各组间外周血T淋巴细胞亚群[CD3^(+)、CD4^(+)、调节性T细胞(Treg细胞)]、细胞因子[白细胞介素-10(IL-10)、白细胞介素-2(IL-2)、转化生长因子-β(TGF-β)]水平,利用Spearman相关性分析评价血T淋巴细胞亚群、细胞因子与CIN分级的关系。结果宫颈炎症组的CD3^(+)、CD4^(+)水平均高于CINⅠ组、CINⅡ组、CINⅢ组,CINⅠ组的CD3^(+)、CD4^(+)水平均高于CINⅡ组、CINⅢ组,CINⅡ组的CD3^(+)、CD4^(+)水平均高于CINⅢ组,差异有统计学意义(P<0.05);宫颈炎症组的Treg细胞水平低于CINⅠ组、CINⅡ组、CINⅢ组,CINⅠ组的Treg细胞水平低于CINⅡ组、CINⅢ组,CINⅡ组的Treg细胞水平低于CINⅢ组,差异有统计学意义(P<0.05)。宫颈炎症组的IL-2水平高于CINⅠ组、CINⅡ组、CINⅢ组,CINⅠ组的IL-2水平高于CINⅡ组、CINⅢ组,CINⅡ组的IL-2水平高于CINⅢ组,差异有统计学意义(P<0.05);宫颈炎症组的IL-10、TGF-β水平均低于CINⅠ组、CINⅡ组、CINⅢ组,CINⅠ组的IL-10、TGF-β水平均低于CINⅡ组、CINⅢ组,CINⅡ组的IL-10、TGF-β水平均低于CINⅢ组,差异有统计学意义(P<0.05)。Spearman相关性分析结果显示,T淋巴细胞亚群中,CD3^(+)、CD4^(+)与CIN分级呈负相关(r=-0.474、-0.491,P<0.05),Treg细胞与CIN分级呈正相关(r=0.397,P<0.05);细胞因子中,IL-2与CIN分级呈负相关(r=-0.557,P<0.05),IL-10、TGF-β与CIN分级呈正相关(r=0.405、0.417,P<0.05)。结论T淋巴细胞亚群、细胞因子水平变化与HR-HPV持续感染患者不同宫颈病变发生发展中发挥着重要作用,对于指导临床诊疗及阻断宫颈癌发生具有重要意义。
