Long non-coding RNAs (lncRNAs) have gradually become a research hotspot in recent years. The abnormal expression of some lncRNAs has been proven to promote tumorigenesis and progression. Among the lncRNAs, metastasis-associated lung adenocar-cinoma transcript 1 (MALAT-1) has attracted considerable attention in various tumor studies, particularly lung cancer. Therefore, the mechanism in which MALAT-1 regulates the cellular activities of tumors should be analyzed. This review mainly discusses the molecu-lar structure, biological function, and role of MALAT-1 in regulating cell proliferation, tumor metastasis, cell cycle, apoptosis, and so on. Furthermore, the role of MALAT-1 in epigenetic regulation is appropriately illustrated to provide a novel perspective in literature on the prevention and treatment of tumors.

Objective To investigate the infection of 23 kinds of human papillomavirus ( HPV) subtypes in female cervical epithelium samples and to analyze their relationships with age and results of cyto-logic test in Haikou area. Methods A total of 4 037 local healthy women were enrolled in this study from July 2013 to August 2016, 1 967 of whom received cervical cytology test. Cervical cell samples collected from those women were detected for HPV typing by using PCR-reverse dot blot hybridization. Results (1) The total positive rate of HPV in 4 037 samples was 22. 15% (894 cases), and the detection rates of carci-nogenic, possibly carcinogenic and non-carcinogenic HPV were 16. 13%, 3. 99% and 5. 55% (651, 161 and 224 cases), respectively. The positive rates of 6 genotypes were high, which were HPV52, 53, 81, 51, 16 and 58 in turn. (2) The detection rates of carcinogenic, possibly carcinogenic HPV and some of the gen-otypes (HPV18, 52, 53, 66) increased with age (all P<0. 05). (3) Multiple infection in HPV-positive women accounted for 24. 38% (218/894), in which the infection rates of carcinogenic types declined with age and the numbers of HPV genotypes in carcinogenic infections were negatively correlated with age ( both P<0. 05). (4) Only 2. 49% (49/1 967) of the samples were positive for cervical cytologic test, classified into the ≥ASC-US ( atypical squamous cells of undetermined significance ) group. The detection rates of eight kinds of carcinogenic and two kinds of possibly carcinogenic HPV in≥ASC-US group were significantly higher than those in the negative (no intraepithelial lesion or malignant lesion, NILM) group (all P<0. 05). Conclusion This study indicates that Haikou women have higher rates of HPV infection, especially the eld-erly group. HPV subtype infections present some regional characteristics and are mainly single type infec-tion. Cervical cancer screening should be combined with tests for HPV and cytology analysis to improve its effectiveness.
