Abstract: Objective To investigate the correlation between persistent and non-persistent HPV infection and vaginal microecology and cervical lesions, and to provide the basis for HPV prevention and treatment. Methods In this prospective study, 229 female patients with high-risk type (HR-HPV) were selected for cervical cytology and vaginal microecological examination in the gynecological outpatient department of Baise Maternal and Child Health Hospital from January 2018 to June 2021. The patients were followed up for 1 year to detect persistent HR-HPV infection. The relationship between HR-HPV persistent infection and vaginal microecology and cervical lesions was analyzed using the HPV-negative group as a control. Results Among 229 patients with HR-HPV, there were 109 patients with persistent HR-HPV infection and 120 patients with non-persistent HR-HPV infection in 1-year follow-up, and the incidence of persistent HR-HPV infection was 47.6%. In the HR-HPV persistent and non-persistent infection and HPV-negative groups, the bacterial vaginal incidence was 20.2%, 15.0% and 8.6%, respectively; vulvovaginal candidiasis was 19.3%, 13.3% and 7.9%, respectively; trichomoniasis vaginitis was 12.8%, 9.2% and 4.5%, respectively; mixed infection was 10.1%, 6.7% and 2.7%; H2O2 detection rate was 24.8%, 18.3% and 12.0%,the positive rate of pH value was 52.3%, 40.8% and 36.4%, and microecological normal detection rate was 22.9%, 32.7% and 40.2%, respectively. There were significant differences among the three groups (χ2=10.634, 10.522, 9.010, 9.374, 10.054, 8.268, P<0.01). In the HR-HPV persistent and non-persistent infection groups, the rates of atypical squamous cell detection were 12.8% and 10.0%, and 8.3% and 4.2% for low-grade squamous cell lesions, and 4.6% and 1.7% for high-grade squamous cell carcinoma, 2.8% and 0 for squamous cell carcinoma, respectively. There was no significant difference in the composition of atypical squamous cells between the two groups (χ2=4.358, P>0.05), there were significant differences in the composition of low-grade, high-grade and squamous cell carcinoma (χ2=11.472, 12.685, 11.378, P<0.01). Spearman rank correlation analysis showed that the presence or extent of HPV infection was positively correlated with bacterial vaginosis, vulvovaginal candidiasis, trichomonal vaginitis and mixed infection (P<0.05), positively correlated with H2O2, sialdase, leucocyte esterase,pH positive and positive for all four items (P<0.05), negatively correlated with microecology (P<0.01), positively correlated with low grade, high grade and squamous cell carcinoma (P<0.01), and not significantly correlated with atypical squamous cell carcinoma (P>0.05). Conclusion Persistent cervical HPV infection is an important factor of dysregulation in vaginal microecology and aggravates the degree of dysregulation in vaginal microecology, which is related to the development of cervical lesions.

Abstract: Objective To explore the correlation between lung function in patients with chronic obstructive pulmonary disease (COPD) and tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β) levels in exhaled breath condensate (EBC), and to provide a convenient methodological basis for the diagnosis and treatment of COPD and the determination of its efficacy. Methods A total of 81 COPD patients and 40 healthy controls were selected from the respiratory department of the Fourth Affiliated Hospital of Guangzhou Medical University from August 2020 to February 2022 as the research subjects. The COPD patients were divided into 41 cases in the acute exacerbation group and 40 cases in the remission group according to their status. All participants underwent lung function detection, venous blood and EBC collection, and the levels of TNF-α and IL-1β in EBC and venous blood were analyzed by enzyme-linked immunosorbent assay (ELISA), and correlation analysis was performed by Pearson correlation analysis method. Results The levels of TNF-α and IL-1β in EBC of in the acute exacerbation group, the healthy control group, the remission group were (5.16±0.18) pg/μL and (7.75±0.27) pg/μL, (2.66±0.31) pg/μL and (2.41±0.24） pg/μL, (3.61±0.29) pg/μL and (3.17±0.38) pg/μL, respectively. Compared with the healthy control group, the levels of TNF-α and IL-1β in EBC in the COPD acute exacerbation group were significantly higher than those in the healthy control group and the COPD remission group (F=9.451, 8.217, P<0.001). Serum tests were consistent with this result. Correlation analysis showed that the levels of TNF-α and IL-1β in EBC were significantly positively correlated with the level of serum inflammation levels (P<0.001), while significantly negatively correlated with lung function (P<0.001).  Conclusions TNF-α and IL-1β in EBC are potential biomarkers of inflammation in patients with COPD, and their detection can be used to effectively assess lung function in patients with COPD. 

Objective To summarize the sonographic features and pathological features of ovarian tumor during pregnancy. Methods One hundred and five women with 114 pathologically proved ovarian tumors during pregnancy in Peking Union Medical College Hospital were retrospectively recruited. According to pathological diagnosis, the clinical treatment, the result of the pregnancy and sonographic examinations were reviewed and analyzed. The sonographic features of benign tumors were compared with low-grade malignant tumors. Results Among the 105 pregnant women with a total of 114 ovarian tumors, 65 tumors were found by ultrasound exam. The other 49 tumors were found during cesarean section. The sonographic features of pathologically proved ovarian tumors include regular shape and well-deifned margins, with 58 of benign tumors and 7 of borderline or low-grade malignant tumors. Compared with borderline or low-grade malignant tumors, benign tumors manifested as strong echoes or high echogenic mass without papillae in the tumors (50/58). As for borderline or low-grade malignant group, tumors manifested as papillae within the tumors (5/7). Pathological classiifcation of the 114 ovarian tumors included 84 germ cell tumors, 19 epithelial tumors, 9 sex cord-stromal tumors, and 2 germ cell tumors combined epithelial tumors. Surgical treatments were performed in 7 cases during the ifrst trimester, while 11 cases during the second trimester, and 87 cases during the third trimester. Pregnancy outcome of the 105 pregnant women included term delivery in 82 cases, premature delivery in 18 cases, artiifcial abortion during ifrst trimester in 4 cases, and induced abortion during second trimester in 1 case. Conclusions Most ovarian tumors treated in pregnancy are benign. The sonographic features of benign tumors include regular shape with well-deifned margins, strong echoes or high echogenic mass within the tumors. While the sonographic features of borderline or malignant tumors include papillae within the tumors. Ultrasound assessment of ovarian tumors can help to determine the risk of malignancy and guide the surgical management.
