HIV-1 Subtype Diversity and Factors Affecting Drug Resistance among Patients with Virologic Failure in Antiretroviral Therapy in Hainan Province, China, 2014-2020.

Objective: This study aimed to determine the HIV-1 subtype distribution and HIV drug resistance (HIVDR) in patients with ART failure from 2014 to 2020 in Hainan, China.

Methods: A 7-year cross-sectional study was conducted among HIV/AIDS patients with ART failure in Hainan. We used online subtyping tools and the maximum likelihood phylogenetic tree to confirm the HIV subtypes with sequences.

Magnetic resonance-guided repeat biopsy of suspicious malignant lung lesions after an initial negative computed tomography-guided Biopsy.

Objective: This study sought to establish the diagnostic utility of performing a second biopsy using an magnetic resonance (MR)-guided percutaneous transthoracic needle biopsy (PTNB) approach in patients with suspicious malignant lung lesions that had already undergone an initial negative computed tomography (CT)-guided biopsy.

Materials And Methods: This study evaluated 31 patients with suspicious lung lesions (18 males, 13 females; mean age: 62.1 ± 11.

Long non-coding RNA LINC00968 acts as oncogene in NSCLC by activating the Wnt signaling pathway.

Long non-coding RNAs (lncRNAs) have played critical roles in a variety of cancers, including non-small cell lung cancer (N SCLC). In our study, we focused on the biological function and clinical significance of lncRNA LINC00968 in NSCLC. It was indicated that LINC00968 was significantly increased in LUAD tissues, LUSC tissues and NSCLC cells compared to their corresponding controls.

Mesenchymal stem cells-regulated Treg cells suppress colitis-associated colorectal cancer.

Introduction: Previous studies have produced controversial results regarding whether mesenchymal stem cells (MSCs) promote or inhibit tumor development. Given the dual role of MSCs in inflammation and cancer, in this study the colitis-associated colorectal cancer (CAC) model was used to examine whether umbilical cord tissue-derived MSCs could prevent neoplasm by inhibiting chronic inflammation.

Methods: MSCs were obtained and identified using flow cytometry.

Serum IL-17F combined with VEGF as potential diagnostic biomarkers for oral squamous cell carcinoma.

Although interleukin (IL) 17A can promote angiogenesis in several tumors, there are limited clinical evidences on cancer about the correlation between serum vascular endothelial growth factor (VEGF) and IL-17F, which is the most homologous to IL-17A. In this study, serum concentration of IL-17F and VEGF from healthy (n = 28), leukoplakia (n = 15), and oral squamous cell carcinoma (OSCC) groups (n = 85) were assessed and showed that IL-17F level was remarkably downregulated from healthy group (394.3 pg/ml) to OSCC group (82.

[Development of the high resolution melting method for genotyping CYP2C9*3 (1075A/C, rs1057910) and VKORC1 (-1639A/G, rs9923231)].

Objective: To establish the high-resolution melting curve (HRM) approach for genotyping CYP2C9*3 (1075A/C, rs1057910) and VKORC1 (-1639A/G, rs9923231) and explore its value on estimation of the Warfarin initial dose in comparison with various traditional genotyping methods.

Methods: CYP2C9*3 (1075A/C, rs1057910) and VKORC1 (-1639A/G, rs9923231) genotyping was detected in 100 patients receiving Warfarin therapy by the newly developed HRM method and traditional genotyping methods including PCR-restriction fragment length polymorphism (PCR-RFLP), TaqMan probe and DNA sequencing.

Results: The results of the genotypes obtained from above mentioned methods to detect CYP2C9*3 (1075A/C, rs1057910) and VKORC1 (-1639A/G, rs9923231) were similar and consistent.

[Relationship between EPHX2 gene polymorphism and essential hypertension in Kazaks and Hans in Xinjiang].

Objective: To investigate the association between rs751141 gene polymorphisms in EPHX2 gene and essential hypertension in Kazak and Han in Xinjiang.

Methods: A total of 267 essential hypertensive patients in Kazaks, 368 essential hypertensive patients in Hans, 284 normotensive controls in Kazaks and 348 normotensive controls in Hans were enrolled in this study. TaqMan assay was used to detect the rs751141 G/A gene polymorphisms of EPHX2 gene.

Polymorphisms of genes in nitric oxide-forming pathway associated with ischemic stroke in Chinese Han population.

Aim: To investigate the association of polymorphisms in four critical genes implicated in the NO-forming pathway with ischemic stroke (IS) in a Chinese Han population.

Methods: DNA samples of 558 IS patients and 557 healthy controls from Chinese Han population were genotyped using the Taqman(TM) 7900HT Sequence Detection System. Six SNPs (rs841, rs1049255, rs2297518, rs1799983, rs2020744, rs4673) of the 4 related genes (eNOS, iNOS, GCH1, and CYBA) in the NO forming pathway were analyzed using the SPSS 13.

Exploring epistatic relationships of NO biosynthesis pathway genes in susceptibility to CHD.

Aim: To assess the epistatic relationships of nitric oxide (NO) biosynthesis pathway genes in susceptibility to coronary heart disease (CHD).

Methods: A total of 2142 subjects enrolled in two case-control studies was genotyped for 7 single-nucleotide polymorphisms (SNP) within NO biosynthesis pathway genes using TaqMan assays. The association analyses were performed at both SNP and haplotype levels.

C-reactive protein polymorphisms and genetic susceptibility to ischemic stroke and hemorrhagic stroke in the Chinese Han population.

Aim: The inflammatory marker C-reactive protein (CRP) has been strongly correlated with the risk of cardiovascular disease. Some single-nucleotide polymorphisms (SNPs) have been reported to be associated with serum CRP levels. In this study, we assessed the genetic association between SNPs within the CRP gene and ischemic and hemorrhagic stroke in the Han Chinese population.
