This study aimed to explore the relation between lymphocyte to high-density lipoprotein ratio (LHR) and pulmonary function of chronic obstructive pulmonary disease (COPD) patients compared with neutrophil-lymphocyte ratio (NLR) and platelet-lymphocyte ratio (PLR). Patients and Methods: In total, 154 participants (n = 77 with COPD and n = 77 without COPD) were recruited. LHR, NLR, PLR, lung function and other data were collected and compared. Pearson's correlation test and the receiver operating characteristics curves were used to compare the utility of LHR, NLR and PLR. Besides, univariate and multivariate logistic regression analyses were conducted. Results: COPD patients with poorer lung function had a lower LHR level (P < 0.001). In low LHR group, more patients underwent greater airflow limitation than the other group (P = 0.006). LHR positively correlated with forced expiratory volume in 1 second in percent of the predicted value (FEV 1 %) (r = 0.333, P = 0.003). At a cutoff value of 2.08, the sensitivity and specificity of LHR in predicting FEV 1 % < 50 were 93.2% and 55.6%, respectively, with an AUC of 0.770 (P = 0.001) better than NLR and PLR. Based on logistic regression analyses, it was proved that LHR was associated with decreased risk of FEV 1 <50% predicted in COPD patients (odds ratio = 0.198, 95% CI: 0.048-0.811, P = 0.024). Conclusion: In contrast with NLR and PLR, LHR has higher accuracy for predicting pulmonary function in COPD; lower LHR level is independently associated with poorer pulmonary function.

ObjectivesThe Cervista® high-risk human papillomavirus (HR-HPV) test was evaluated as a primary screening method for cervical cancer in women aged ≥21 years and was compared with different screening and triage combinations.Materials and methodsA nested case–control study within the Fujian provincial Cervical Lesion Screening Cohorts was used to evaluate the Cervista test as the primary cervical screening method in a hospital-based population. Strategy 1 primarily screened using a cytology screen with HR-HPV testing used for triage. Strategy 2 primarily screened using cytology and HR-HPV co-testing. Strategy 3 primarily screened using HR-HPV testing and triaged HPV-positive women based on cytology. Strategy 4 primarily screened using HR-HPV testing and referred A9 pool HPV-positive women to colposcopy directly, whereas non-A9 HPV-positive women were triaged using cytology.ResultsThere were 10,183 women included in this study; 16.49% (1677/10,183) were HR-HPV-positive, 9.52% had abnormal cytology, and 9907 women were normal during followup. A total of 276 women were diagnosed with cervical intraepithelial neoplasia 2 or worse (CIN2+), 197 with CIN3 or worse (CIN3+), and 70 with cervical cancer. Moreover, 10.15% (20/197) women who were CIN3+ were identified as cytology-negative, while 8.63% (17/197) were HR-HPV negative (P>0.05). The cumulative risk rate for HPV–/cytology– was 0.836 (95% CI, 0.424–1.648) in CIN3+ cases. Strategy 4 yielded the highest sensitivity for CIN2+ or CIN3+ and the lowest positive predictive value for CIN2+ or CIN3+ among the four screening strategies.ConclusionThe Cervista HR-HPV test can provide a reliable and sensitive clinical reference for the cervical cancer primary screen.
