This study aims to clarify host factors of IFN treatment in the treatment of chronic hepatitis B (CHB) patients by screening the differentially expressed genes of IFN pathway CHB patients with different response to interferon (IFN) therapy. Three cases were randomly selected in IFN-responding CHB patients (Rs), non-responding CHB patients (NRs) and healthy participants, respectively. The human type I IFN response RT2 profiler PCR array was used to detect the expression levels of IFN-related genes in peripheral blood monocytes (PBMCs) from healthy participants and CHB patients before and after Peg-IFN-α 2a treatment. The results showed that more differentially expressed genes appeared in Rs group than NRs group after IFN treatment. Comparing with healthy participants, IFNG, IL7R, IRF1, and IRF8 were downregulated in both Rs and NRs group before IFN treatment; CXCL10, IFIT1, and IFITM1 were upregulated in the Rs; IL13RA1 and IFI35 were upregulated in the NRs, while IFRD2, IL11RA, IL4R, IRF3, IRF4, PYHIN1, and ADAR were downregulated. The expression of IL15, IFI35 and IFI44 was downregulated by 4.09 (t = 10.58, P < 0.001), 5.59 (t = 3.37, P = 0.028) and 10.83 (t = 2.8, P = 0.049) fold in the Rs group compared with the NRs group, respectively. In conclusion, IFN-response-related gene array is able to evaluate IFN treatment response by detecting IFN-related genes levels in PBMC. High expression of CXCL10, IFIT1 and IFITM1 before treatment may suggest satisfied IFN efficacy, while high expression of IL13RA1, IL15, IFI35 and IFI44 molecules and low expression of IFRD2, IL11RA, IL4R, IRF3, IRF4, PYHIN1 and ADAR molecules may be associated with poor IFN efficacy.
ObjectiveTo systematically review the incidence of social isolation in Chinese elderly population. MethodsCNKI, WanFang Data, VIP, CBM, PubMed, EMbase, Web of Science and CENTRAL databases were electronically searched to collect studies on the incidence of social isolation in China from inception to May 2022. Two reviewers independently screened literature, extracted data and assessed the risk of bias of the included studies, then, meta-analysis was performed by using Stata 15.1 software. ResultsA total of 20 studies involving 86 111 subjects were included. Meta-analysis results showed that the incidence of social isolation among the elderly in China was 27.54% (95%CI 22.15% to 57.74%). The results of subgroup analysis showed that gender, age, educational level, marital status, self-assessment of health, living style, year of publication, and region surveyed were all influential factors of the incidence of social isolation among the elderly in China. ConclusionCurrent evidence shows that the incidence of social isolation among the elderly in China is relatively high. Due to the limited quality and quantity of the included studies, more high quality studies are needed to verify the above conclusion.
