Abstract
OBJECTIVES Alcohol consumption is not uncommon among people with HIV (PWH) and may exacerbate HIV-induced intestinal damage, and further lead to dysbiosis and increased intestinal permeability. This study aimed to determine the changes in the faecal microbiota and its association with alcohol consumption in HIV-infected patients. METHODS A cross-sectional survey was conducted between November 2021 and May 2022, and 93 participants were recruited. To investigate the alterations of alcohol misuse on fecal microbiology in HIV-infected individuals, we performed 16s rDNA gene sequencing on fecal samples from the low to moderate drinking (n=21) and non-drinking (n=72) groups. RESULTS Comparison between groups using alpha and beta diversity showed that the diversity of stool microbiota in the low to moderate drinkinge group did not differ from that of the non-drinking group (all P>0.05). The Linear discriminant Analysis effect size (LEfSe) algorithm was to determine the bacterial taxa associated with alcohol consumption, and the results showed altered fecal bacterial composition in HIV-infected patients who consumed alcohol, with Coprobacillus, Pseudobutyrivibrio and Peptostreptococcaceae enriched, and Pasteurellaceae and Xanthomonadaceae were depleted. In addition, by using the Kyoto Encyclopedia of Genes and Genomes (KEGG) functional microbiome features were also found to be altered in the low to moderate drinking group, showing a reduction in metabolic pathways (P=0.036) and cardiovascular disease pathway (P=0.006). CONCLUSION Low to moderate drinking will change the composition, metabolism and cardiovascular disease pathway of the gut microbiota of HIV-infected patients.

Abstract
INTRODUCTION Cutaneous metastasis from gastric cancer is very rare. The understanding of this disease is incomplete. This situation delays its diagnosis and treatment, followed by poor prognosis. Here, we first report a study based on a network to improve the diagnosis, treatment and prognosis of cutaneous metastasis from gastric cancer. METHODS A comprehensive search of PubMed was performed. All studies on cutaneous metastasis from gastric cancer were collected. The publication date was limited from 2000 to the present, and the language was limited to English. SPSS 26.0 was employed for statistical analysis. RESULTS Seventy-two patients were included. The average patient age was 60.0 ± 16.0 years. In total, 72.2 % of the patients were male. The most common manifestation was nodular skin lesions (45.8 %). The metastases generally presented as multiple lesions (61.1 %). The most common metastasis location was the thoracoabdominal wall (56.9 %). 64.7 % of the patients simultaneously had extracutaneous metastases. Most of the tumors were poorly differentiated carcinomas (87.5 %), and 66.1 % had signet ring cells. 40.8 % of the cutaneous metastases presented as primary manifestations. Only 9.6 % had their diagnosis as soon as the cutaneous metastasis emerged. Systemic chemotherapy (65.6 %) was the most common treatment strategy, followed by radical surgery (12.5 %). The median overall survival was only 6 months. The median overall survival of 5 patients with resected tumors was 48 months. CONCLUSION Cutaneous metastasis from gastric cancer usually manifests as an emerged nodule or erysipelas-like skin lesion. Resection of the cutaneous lesion could be helpful for patients with local metastases.

Abstract
OBJECTIVE To investigate the relationship between metabolomic profiles, genome-wide polygenic risk scores (PRSs) and risk of rheumatoid arthritis (RA). METHODS 143 nuclear magnetic resonance-based plasma metabolic biomarkers were measured among 93 800 participants in the UK Biobank. The Cox regression model was used to assess the associations between these metabolic biomarkers and RA risk, and genetic correlation and Mendelian randomisation analyses were performed to reveal their causal relationships. Subsequently, a metabolic risk score (MRS) comprised of the weighted sum of 17 clinically validated metabolic markers was constructed. A PRS was derived by assigning weights to genetic variants that exhibited significant associations with RA at a genome-wide level. RESULTS A total of 620 incident RA cases were recorded during a median follow-up time of 8.2 years. We determined that 30 metabolic biomarkers were potentially associated with RA, while no further significant causal associations were found. Individuals in the top decile of MRS had an increased risk of RA (HR 3.52, 95% CI: 2.80 to 4.43) compared with those below the median of MRS. Further, significant gradient associations between MRS and RA risk were observed across genetic risk strata. Specifically, compared with the low genetic risk and favourable MRS group, the risk of incident RA in the high genetic risk and unfavourable MRS group has almost elevated by fivefold (HR 6.10, 95% CI: 4.06 to 9.14). CONCLUSION Our findings suggested the metabolic profiles comprising multiple metabolic biomarkers contribute to capturing an elevated risk of RA, and the integration of genome-wide PRSs further improved risk stratification.

Abstract
BACKGROUND The disease burden attributable to chronic obstructive pulmonary disease (COPD) is significant worldwide. Some studies have linked exposure to air pollution to COPD, but there has been little research on this. METHODS We aimed to assess the COPD-related disease burden attributable to air pollution from multiple epidemiological perspectives. This study conducted a three-stage analysis. Firstly, we reported on the burden of disease worldwide in 2019 by different subgroups including sex, age, region, and country. Secondly, we studied the trends in disease burden from 1990 to 2019. Finally, we explored the association of some national indicators with disease burden to look for risk factors. RESULTS In 2019, the death number of COPD associated with air pollution accounted for 2.32% of the total global death, and the number of DALY accounted for 1.12% of the global DALY. From 1990 to 2019, the death number of COPD associated with air pollution increased peaked at 1.41 million in 1993, fluctuated, and then declined. We found the same temporal pattern of DALY. The corresponding age-standardized rates had been falling. At the same time, the burden of COPD associated with air pollution was also affected by some national indicators. CONCLUSIONS This study indicated that air pollution-related COPD contributed to a significant global disease burden. We called for health policymakers to take action and interventions targeting vulnerable countries and susceptible populations.

Abstract
BACKGROUND AND PURPOSE Necroptosis plays an essential role in acute kidney injury and is mediated by receptor-interacting protein kinase 1 (RIPK1), receptor-interacting protein kinase 3 (RIPK3), and mixed lineage kinase domain-like pseudokinase (MLKL). A novel RIPK3 inhibitor, compound 42 (Cpd-42) alleviates the systemic inflammatory response. The current study was designed to investigate whether Cpd-42 exhibits protective effects on acute kidney injury and reveal the underlying mechanisms. EXPERIMENTAL APPROACH The effects of Cpd-42 were determined in vivo through cisplatin- and ischaemia/reperfusion (I/R)-induced acute kidney injury and in vitro through cisplatin- and hypoxia/re-oxygenation (H/R)-induced cell damage. Transmission electron microscopy and periodic acid-Schiff staining were used to identify renal pathology. Cellular thermal shift assay and RIPK3-knockout mouse renal tubule epithelial cells were used to explore the relationship between Cpd-42 and RIPK3. Molecular docking and site-directed mutagenesis were used to determine the binding site of RIPK3 with Cpd-42. KEY RESULTS Cpd-42 reduced human proximal tubule epithelial cell line (HK-2) cell damage, necroptosis and inflammatory responses in vitro. Furthermore, in vivo, cisplatin- and I/R-induced acute kidney injury was alleviated by Cpd-42 treatment. Cpd-42 inhibited necroptosis by interacting with two key hydrogen bonds of RIPK3 at Thr94 and Ser146, which further blocked the phosphorylation of RIPK3 and mitigated acute kidney injury. CONCLUSION AND IMPLICATIONS Acting as a novel RIPK3 inhibitor, Cpd-42 reduced kidney damage, inflammatory response and necroptosis in acute kidney injury by binding to sites Thr94 and Ser146 on RIPK3. Cpd-42 could be a promising treatment for acute kidney injury.

Abstract
BACKGROUND This study conducted a survey of men who have sex with men (MSM) in Maanshan City of Anhui Province to assess the risk behaviors related to human immunodeficiency virus (HIV) infection. METHODS A cross-sectional survey was conducted from June 2016 to June 2019. The MSM were recruited by a peer-driven sampling method. A face-to-face interview with anonymous questionnaire was used for data collection. The information collected by the survey was summarized and epidemiology described the basic characteristics of MSM, and then the related factors were statistically analyzed. RESULTS A total of 934 MSM were recruited with a average age was 30.5 (SD = 8.90) years old, including 816 (87.4%) HIV negative participants and 118 (12.6%) HIV positive ones. This study showed that freelancer (OR = 4.02, 95% CI: 1.96-8.23), scope of sexual partners distribution (OR = 1.78, 95% CI: 1.36-2.33), number of male sexual partners (OR = 2.11, 95% CI: 1.47-3.02), role of anal sex with men was receptive (OR = 2.54, 95% CI: 1.25-5.13) and versatile (OR = 2.34, 95% CI: 1.31-4.19) and non-steady sex partners (OR = 2.14, 95% CI: 1.56-2.93) were risk factors for HIV infection, while monthly income (OR = 0.68, 95% CI: 0.57-0.82), education level (OR = 0.79, 95% CI: 0.66-0.95), frequency of condom use (OR = 0.53, 95% CI: 0.35-0.81) and number of oral sex partners (OR = 0.35, 95% CI: 0.24-0.51) in the past 6 months were protective factors for HIV infection. CONCLUSION Risk behaviors were common in MSM, and urgent need for targeted and comprehensive interventions to reduce risky sexual behaviour and to prevent HIV infection in MSM.

Abstract
BACKGROUND Evidence for a potential link between air pollution and rheumatoid arthritis (RA) is inconsistent, and the modified effect of genetic susceptibility on the relationship between air pollution and RA has not been well studied. OBJECTIVE Using a general population cohort from the UK Biobank, this study aimed to investigate the associations between various air pollutants and the risk of incident RA and to further estimate the impact of combined exposure to ambient air pollutants on the risk of developing RA under the modification effect of genetic predisposition. METHODS A total of 342,973 participants with completed genotyping data and who were free of RA at baseline were included in the study. An air pollution score was constructed by summing the concentrations of each pollutant weighted by the regression coefficients with RA from single-pollutant models to assess the combined effect of air pollutants, including particulate matter (PM) with diameters ≤2.5μm (PM2.5), between 2.5 and 10μm (PM2.5-10), and ≤10μm (PM10), as well as nitrogen dioxide (NO2) and nitrogen oxides (NOx). In addition, the polygenic risk score (PRS) of RA was calculated to characterize individual genetic risk. The Cox proportional hazard model was used to estimate hazard ratios (HRs) and 95% confidence intervals (95% CIs) of associations of single air pollutant, air pollution score, or PRS with incident RA. RESULTS During a median follow-up time of 8.1 y, 2,034 incident events of RA were recorded. The HRs (95% CIs) of incident RA per interquartile range increment in PM2.5, PM2.5-10, PM10, NO2, and NOx were 1.07 (1.01, 1.13), 1.00 (0.96, 1.04), 1.01 (0.96, 1.07), 1.03 (0.98, 1.09), and 1.07 (1.02, 1.12), respectively. We also found a positive exposure-response relationship between air pollution score and RA risk (pTrend=0.000053). The HR (95% CI) of incident RA was 1.14 (1.00, 1.29) in the highest quartile group compared with the lowest quartile group of the air pollution score. Furthermore, the results of the combined effect of air pollution score and PRS on the RA risk showed that the risk of RA incidence in the highest genetic risk and air pollution score group was almost twice that of the lowest genetic risk and air pollution score group [incidence rate (IR) per 100,000 person-years: 98.46 vs. 51.19, and HR= 1.73 (95% CI: 1.39, 2.17) vs. 1 (reference)], although no statistically significant interaction between the air pollution and genetic risk for incident RA was found (pInteraction>0.05). DISCUSSION The results revealed that long-term combined exposure to ambient air pollutants might increase the risk of RA, particularly in those with high genetic risk. https://doi.org/10.1289/EHP10710.

Abstract
Concerns are growing about the adverse health effects of ambient temperature and ambient temperature changes. However, the association between ambient temperature and ambient temperature changes on the risk of warts outpatient visits is poorly understood. Our study used the distributed lag non-linear model (DLNM) aimed to evaluate the association between ambient temperature, ambient temperature changes (including temperature change between neighboring days (TCN) and diurnal temperature range (DTR)), and warts outpatient visits. We also performed subgroup analyses in order to find susceptible populations by gender and age groups. The maximum relative risk (RR) of low ambient temperature (0 °C) for warts outpatient visits was 1.117 (95% CI: 1.041-1.198, lag 04 days), and the maximum RR of high ambient temperature (32 °C) for warts outpatient visits was 1.318 (95% CI: 1.083-1.605, lag 07 days). The large temperature drop (TCN = - 3 °C) decreased the risk of warts visits, with the lowest RR value at the cumulative exposure of lag 7 days (RR = 0.888, 95% CI: 0.822-0.959), and the large temperature rise (TCN = 2 °C) increased the risk of warts visits, with the highest RR value at the cumulative exposure of lag 7 days (RR = 1.080, 95% CI: 1.022-1.142). Overall, both low and high ambient temperatures and large temperature rise can increase the risk of warts visits, while large temperature drop is a protective factor for warts visits. However, we did not find any association between DTR and warts visits. Furthermore, subgroup analyses showed that males and the young (0-17 years old) were more sensitive to low and high ambient temperatures, and the elderly (≥ 65 years old) were more susceptible to TCN. The results may provide valuable evidence for reducing the disease burden of warts in the future.

Abstract
Objective Gut fungi, as symbiosis with the human gastrointestinal tract, may regulate physiology via multiple interactions with host cells. The plausible role of fungi in systemic lupus erythematosus (SLE) is far from clear and need to be explored. Methods A total of 64 subjects were recruited, including SLE, rheumatoid arthritis (RA), undifferentiated connective tissue diseases (UCTDs) patients and healthy controls (HCs). Fecal samples of subjects were collected. Gut fungi and bacteria were detected by ITS sequencing and 16S rRNA gene sequencing, respectively. Alpha and beta diversities of microbiota were analyzed. Linear discriminant analysis effect size analysis was performed to identify abundance of microbiota in different groups. The correlation network between bacterial and fungal microbiota was analyzed based on Spearman correlation. Results Gut fungal diversity and community composition exhibited significant shifts in SLE compared with UCTDs, RA and HCs. Compared with HCs, the alpha and beta diversities of fungal microbiota decreased in SLE patients. According to principal coordinates analysis results, the constitution of fungal microbiota from SLE, RA, UCTDs patients and HCs exhibited distinct differences with a clear separation between fungal microbiota. There was dysbiosis in the compositions of fungal and bacterial microbiota in the SLE patients, compared to HCs. Pezizales, Cantharellales and Pseudaleuria were enriched in SLE compared with HCs, RA and UCTDs. There was a complex relationship network between bacterial and fungal microbiota, especially Candida which was related to a variety of bacteria. Conclusion This study presents a pilot analysis of fungal microbiota with diversity and composition in SLE, and identifies several gut fungi with different abundance patterns taxa among SLE, RA, UCTDs and HCs. Furthermore, the gut bacterial-fungal association network in SLE patients was altered compared with HCs.

Abstract
OBJECTIVE Previous observational studies demonstrated that a subset of patients with systemic lupus erythematosus (SLE) have markedly short telomere length (TL) in leukocytes. The purpose of this study is to test whether leukocyte TL is causally associated with risk of SLE. METHODS A two-sample Mendelian randomization (TSMR) analysis was applied to estimate causality of TL on SLE in European populations. A replication TSMR study using Asian genetic data was also conducted. A backward MR analysis was then performed to test effects of SLE on TL. The autoantibodies targeting telomere-associated protein (TERF1 autoantibodies) were detected in SLE, healthy controls and rheumatoid arthritis (RA). RESULTS The results of inverse-variance weighted method (OR=2.96; 95% CI 1.58, 5.55; P<0.001) showed strong evidence for casual relationship between longer TL and risk of SLE in people with European ancestry. The outcomes of MR-Egger regression (OR=29.46, 95% CI 3.02, 287.60; P=0.033), and MR-PRESSO (OR=3.62; 95% CI 2.03, 6.46; P=0.002) also showed that longer TL was significantly associated with increased risk of SLE in European population. Sensitivity analyses using different methods and summary data sets showed that the results were still broadly consistent. Replication MR study using Asian genetic data yielded similar findings. However, the backward MR analysis showed that genetically predicted SLE was not causally associated with TL. In addition, we found that TERF1 autoantibodies were present in 2/40 (5.0%) patients with SLE. CONCLUSION In contrast with previous observational studies, MR analyses found that longer TL is significantly associated with increased risk of SLE.

Abstract
BACKGROUND N6-methyladenosine (m6A) modification is widespread in eukaryotic mRNA, regulated by m6A demethylase, AlkB homolog 5 (ALKBH5). However, the role of m6A in systemic lupus erythematosus (SLE) is still obscure. We explored ALKBH5 expression in SLE patients and its effects on T cells. METHODS 100 SLE patients and 110 healthy controls were recruited to investigate the expression of ALKBH5 in peripheral blood mononuclear cells (PBMCs). An additional 32 SLE patients and 32 health controls were enrolled to explore the expression of ALKBH5 in T cells. Then we explored the function of ALKBH5 in T cells by lentivirus. RESULTS The expressions of ALKBH5 were downregulated in both PBMCs and T cells in SLE patients (all P<0.05). In PBMCs: ALKBH5 mRNA levels were associated with complement C4 level in plasma (P<0.05). In T cells: ALKBH5 mRNA levels were downregulated in SLE patients with low complement levels, high anti-dsDNA, anti-Sm, anti-RNP, and proteinuria compared with those without, respectively (all P<0.05); ALKBH5 mRNA levels were negatively related with SLE disease activity index score, erythrocyte sedimentation rate, and anti-dsDNA levels (all P<0.05), and positively correlated with complement C3 and C4 level (all P<0.05). Functionally, the overexpression of ALKBH5 promoted apoptosis and inhibited the proliferation of T cells (all P<0.05). CONCLUSION ALKBH5 expression is downregulated in SLE patients and could affect the apoptosis and proliferation of T cells, but the exact mechanism still needs to be further explored.

Abstract
INTRODUCTION Recommended treatment regimen for HIV infection includes protease inhibitors/ritonavir (PIs/r) combined with two nucleoside reverse transcriptase inhibitors (2NRTIs), that enable to achieve and maintain viral suppression, restore and preserve immune function. However, there were inconsistent findings on the levels of interleukin-6 levels (IL-6). METHODOLOGY Systematic review and meta-analysis were performed to quantify the pooled effects of PIs/r-based ART on serum/plasma IL-6 levels in PLHIV. PubMed, Web of Science, and Embase were searched from the earliest record to November 4, 2020. Data analysis was conducted on Stata version 16 and Review Manager 5.3. A random-effect model was used to compute a pooled effect size and weighted mean difference (WMD) was considered the summary effect size. Heterogeneity between studies was estimated by Cochrane's Q test (chi-square test) and I-square statistic and subgroup analysis were performed to explore the source of heterogeneity. RESULT Initial search identified 3098 records and five studies (seven trials) met inclusion criteria. The pooled mean difference in serum/plasma IL-6 levels from baseline to follow-up was 0.534 pg/ml (95% CI: -0.012, 1.08, P=0.05, I2 =76.4%). In subgroup analysis, there was a significant association between increased serum/plasma IL-6 levels, and age group ≥35 years old, baseline CD4+ counts <350 cell/mm3 , and mean viral load ≥ 4.5 log10 copies/ml. CONCLUSION We found that serum/plasma IL-6 levels increased after combined anti-retroviral therapy (cART) among treatment-naïve individuals who initiated a successful combination of PIs/r with 2NRTIs. This result also highlights the need to monitor serum/plasma IL-6 levels during antiviral therapy, which may aid in the effective future treatment of systemic inflammation and related disorders following elevated IL-6 levels.

Abstract
BACKGROUND Currently, few studies focus on the association between gut microbiota and systemic lupus erythematosus (SLE), and much less studies consider the effect of drug usage. Proton pump inhibitors (PPIs) are commonly used to treat drug-related gastrointestinal damage in SLE patients. Therefore, the purpose of this study is to examine the gut microbiota of SLE patients using PPIs. METHODS Fecal samples from 20 SLE patients with PPIs (P-SLE), 20 SLE patients without PPIs (NP-SLE) and 17 healthy controls (HCs) were obtained. The structure of the bacterial community in the fecal samples was analyzed by 16S rRNA gene sequencing. Redundancy analysis (RDA) was performed to observe the relationship between clinical variables and microbiome composition in P-SLE and NP-SLE patients. Based on the Kyoto Encyclopedia of Genes and Genomes (KEGG) database, functional capabilities of microbiota were estimated. Network analysis was performed to analyze the association of metabolic pathway alterations with altered gut microbiota in P-SLE and NP-SLE patients. RESULTS P-SLE patients exhibited increased alpha-diversity and an altered composition of the gut microbiota compared with NP-SLE patients. The alpha-diversity of NP-SLE patients was significantly lower than HCs but also of P-SLE patients, whose alpha-diversity had become similar to HCs. Compared with NP-SLE patients, the relative abundances of Lactobacillus, Roseburia, Oxalobacter, and Desulfovibrio were increased, while those of Veillonella, Escherichia, Morganella, Pseudomonas and Stenotrophomonas were decreased in P-SLE patients. RDA indicated that PPI use was the only significant exploratory variable for the microbiome composition when comparing SLE patients. KEGG analysis showed that 16 metabolic pathways were significantly different between NP-SLE and P-SLE patients. These metabolic pathways were mainly associated with changes in Escherichia, Roseburia, Stenotrophomonas, Morganella and Alipipes as determined by the network analysis. CONCLUSIONS PPI use is associated with an improved microbiome composition of SLE patients as it 1) increases alpha-diversity levels back to normal, 2) increases the abundance of various (beneficial) commensals, and 3) decreases the abundance of certain opportunistic pathogenic genera such as Escherichia. Validation studies with higher patient numbers are however recommended to explore these patterns in more detail.

Abstract
BACKGROUND LncRNAs are potential biomarkers for SLE, but the epigenetic regulatory mechanisms of N6-methyladenosine (m6A) modification in SLE remain largely unclear. METHODS In this study, we established m6A modification profile and investigated the potential roles of m6A-related lncRNAs in SLE. The m6A modification profile of SLE was established using MeRIP-seq. Four potential m6A related-lncRNAs (linc02446, linc01410, Xist, and PSMB8-AS1) were selected for validation using qRT-PCR, and their expression and association with clinical characteristics with SLE were evaluated. RESULTS Overall, m6A level was lower in patients with SLE than in controls. Compared with controls, the expression of the two m6A related-lncRNAs (Xist and PSMB8-AS1) was downregulated in patients with SLE (all P < 0.05); the linc02446 was up-regulated in PBMCs of patients with SLE (Z=-2.738, P = 0.006), while it was not differentially expressed in T cells (Z=-0.387, P = 0.699). No significant alteration in linc01410 expression was observed in patients (Z=-0.940, P = 0.347). The lower expression levels of Xist and PSMB8-AS1 were associated with many clinical manifestations in patients with SLE (all P < 0.05). Additionally, mRNAs co-expressed with m6A related-lncRNAs (Xist, linc02446, and PSMB8-AS1) also participated in SLE. CONCLUSION These results suggest that m6A methylation and m6A related-lncRNAs might be involved in the pathogenesis of SLE. Thus, our findings provide some clues on the potential function of lncRNAs that m6A modification may target in novel therapeutic or diagnostic strategies for SLE.

Abstract
Rosuvastatin therapy might have an effect on the inflammatory and coagulation biomarkers. However, the evidence about the effect of rosuvastatin therapy on the high-sensitivity C-reactive protein (hsCRP), interleukin-6 (IL-6), and D-dimer levels among people living with human immunodeficiency virus (PLHIV) is still unclear. Therefore, this study investigated the relational effect of rosuvastatin therapy on serum/plasma hsCRP, IL-6 and D-dimer levels in PLHIV. The literature search was done from Embase, PubMed, and Web of Science databases. The review and meta-analysis included studies written in English language up to January 4, 2020. Random effects model was used to evaluate the pooled standard mean difference with 95% confidence interval. A meta-analysis was performed using nine articles with 392 PLHIV. The result revealed that the plasma/serum levels of IL-6 were significantly reduced after the intervention. However, hsCRP and D-dimer levels showed no significant difference (p > .05) between before and after the intervention. The subgroup analysis showed that there was significant association between PLHIV ages <45 years and cohort studies with IL-6 levels. The current CD4+ counts ≥350 cells/mm3 correlated with hsCRP as well as IL-6. Similarly, nadir CD4+ counts ≥200 cells/mm3 and duration of HIV diagnosis <10 years also showed significant association with IL-6 and D-dimer levels. It was also indicated that participants who were under antiretroviral drug for <7 years were significantly associated with hsCRP levels. This study established that IL-6 levels were significantly reduced after the intervention while hsCRP and D-dimer levels showed no significant difference between before and after the intervention.

Abstract
OBJECTIVE Due to the inconsistent results of current studies on the association between urinary and blood vascular cell adhesion molecule-1 (VCAM-1) and systemic lupus erythematosus (SLE) disease activity, we conducted this study and analyzed its influencing factors. METHODS A literature search was conducted in PubMed, EMBASE, Web of Science, and Cochrane Library. Data were extracted from eligible studies to calculate standardized mean differences (SMD) with 95% confidence intervals (CI). Cochrane Q test and I2 statistics were used to examine heterogeneity. The sources of heterogeneity were assessed through sensitivity analysis and subgroup analysis. Publication bias was evaluated by funnel plots and Egger's test. RESULTS A total of 15 studies met the inclusion criteria, including 473 active SLE patients and 674 inactive SLE patients. The random effects model was used for data analysis. In both urine and blood samples, VCAM- 1 level in active SLE patients was significantly higher than those in inactive SLE patients (urine: SMD: 0.769; 95% CI: 0.260-1.278; blood: SMD=0.655, 95% CI: 0.084-1.226). No publication bias was found in this study. CONCLUSION Compared with inactive SLE patients, patients with active SLE have higher levels of VCAM-1 in both urine and blood. VCAM-1 may be a potential indicator of SLE disease activity.

Abstract
OBJECTIVES The present study aimed to discover novel susceptibility loci associated with risk of rheumatoid arthritis (RA). METHODS We performed a new genome-wide association study (GWAS) in Chinese subjects (1027 RA cases and 2879 controls) and further conducted an expanded meta-analysis with previous GWAS summary data and replication studies. The functional roles of the associated loci were interrogated using publicly available databases. Dual-luciferase reporter and cytokine assay were also used for exploring variant function. RESULTS We identified five new susceptibility loci (IL12RB2, BOLL-PLCL1, CCR2, TCF7 and IQGAP1; pmeta <5.00E-08) with same effect direction in each study cohort. The sensitivity analyses showed that the genetic association of at least three loci was reliable and robust. All these lead variants are expression quantitative trait loci and overlapped with epigenetic marks in immune cells. Furthermore, genes within the five loci are genetically associated with risk of other autoimmune diseases, and genes within four loci are known functional players in autoimmunity, which supports the validity of our findings. The reporter assay showed that the risk allele of rs8030390 in IQGAP1 have significantly increased reporter activity in HEK293T cells. In addition, the cytokine assay found that the risk allele of rs244672 in TCF7 was most significantly associated with increased plasma IL-17A levels in healthy controls. Finally, identified likely causal genes in these loci significantly interacted with RA drug targets. CONCLUSION This study identified novel RA risk loci and highlighted that comprehensive genetic study can provide important information for RA pathogenesis and drug therapy.

Abstract
OBJECTIVE Clinical diagnosis of SLE is currently challenging due to its heterogeneity. Many autoantibodies are associated with SLE and are considered potential diagnostic markers, but systematic screening and validation of such autoantibodies is lacking. This study aimed to systematically discover new autoantibodies that may be good biomarkers for use in SLE diagnosis. METHODS Sera from 15 SLE patients and 5 healthy volunteers were analysed using human proteome microarrays to identify candidate SLE-related autoantibodies. The results were validated by screening of sera from 107 SLE patients, 94 healthy volunteers and 60 disease controls using focussed arrays comprised of autoantigens corresponding to the identified candidate antibodies. Logistic regression was used to derive and validate autoantibody panels that can discriminate SLE disease. Extensive ELISA screening of sera from 294 SLE patients and 461 controls was performed to validate one of the newly discovered autoantibodies. RESULTS A total of 31, 11 and 18 autoantibodies were identified to be expressed at significantly higher levels in the SLE group than in the healthy volunteers, disease controls and healthy volunteers plus disease control groups, respectively, with 25, 7 and 13 of these differentially expressed autoantibodies being previously unreported. Diagnostic panels comprising anti-RPLP2, anti-SNRPC and anti-PARP1, and anti-RPLP2, anti-PARP1, anti-MAK16 and anti- RPL7A were selected. Performance of the newly discovered anti-MAK16 autoantibody was confirmed by ELISA. Some associations were seen with clinical characteristics of SLE patients, such as disease activity with the level of anti-PARP1 and rash with the level of anti-RPLP2, anti-MAK16 and anti- RPL7A. CONCLUSION The combined autoantibody panels identified here show promise for the diagnosis of SLE and for differential diagnosis of other major rheumatic immune diseases.

Abstract
Human immunodeficiency virus (HIV) infection results in gut microbiota alteration and this is associated with immune activation and chronic inflammation. The gastrointestinal tract is a primary site of viral replication and thus HIV-induced loss of T-helper (Th) cells in the gut causes impairments in intestinal barriers, resulting in disruptions in intestinal immunity and precipitating into gut dysbiosis. Here, we show that late HIV diagnosis can negatively affect the immunological, virological, and clinical prognosis of the patients with its higher implication at an older age. Further, the review indicates that antiretroviral therapy affects the gut microbiota. We discussed the use of probiotics and prebiotics that have been indicated to play a promising role in reversing gut microbiota alteration in HIV patients. Though there are several studies reported with regard to such alterations in gut microbiota regarding HIV infection, there is a need to provide comprehensive updates. It is, therefore, the objective of this review to present most recently available evidence on the alteration of gut microbiota among HIV patients.

Abstract
OBJECTIVE An increasing number of studies have demonstrated the roles of adipokines in systemic lupus erythematosus (SLE). We aimed to investigate the association of genetic variations of omentin-1, adiponectin, and resistin with SLE susceptibility. METHODS We selected 623 SLE patients and 665 normal controls in the present study. Genotyping of omentin-1 rs2274907, rs35779394, rs79209815, and rs13376023; adiponectin rs16861194 and rs266729; and resistin rs1862513, rs3745368, and rs3745367 was conducted by TaqMan SNP genotyping assays. RESULTS Overall, we found no significant differences in the allele or genotype frequencies of the nine studied SNPs between the SLE patients and controls. However, an increased frequency of the resistin rs3745368 variant was observed in the SLE patients under the dominant model (P = 0.024). In omentin-1, the rs13376023 A allele was found to be related to oral ulcers in SLE patients (P = 0.013), and the rs35779394 C and rs13376023 A allele frequencies were significantly lower in SLE patients with BMI ≥ 24 kg/m2 (P = 0.019, P = 0.033, respectively). For resistin, the frequencies of the rs3745368 AA genotype and A allele were lower in SLE patients with discoid rash (P = 0.036, P = 0.011), and the rs3745368 A allele frequency was higher in SLE patients with lupus nephritis (P = 0.018). The resistin rs3745367 AA genotype and A allele frequencies were related to the occurrence of renal disorder in SLE patients (P = 0.024, P = 0.009). The haplotype analysis showed that the CGA haplotype of resistin was associated with susceptibility to SLE (P = 0.005). No significant associations of plasma omentin-1, adiponectin or resistin levels with their respective genotypes were found in SLE patients. CONCLUSIONS In summary, omentin-1, adiponectin and resistin SNPs are not associated with the genetic background of SLE in Chinese patients. However, omentin-1 and resistin genetic variations might contribute to several clinical phenotypes of SLE.

Abstract
Long non-coding RNAs (lncRNAs) are increasingly recognized to play important roles in multiple autoimmune diseases. This study aimed to evaluate the association of four lncRNAs (ANRIL, lnc-DC, MALAT1, ZFAS1) genes single nucleotide polymorphisms (SNPs) with susceptibility to rheumatoid arthritis (RA) patients, as well as their expression levels. Seventeen SNPs of the four lncRNAs were genotyped in a cohort of 660 RA patients and 710 controls using improved multiple ligase detection reaction (iMLDR). The lncRNAs expressions in peripheral blood mononuclear cells (PBMCs) from 120 RA patients and 120 controls were detected by qRT-PCR. No significant differences were found for the allele and genotype frequencies distribution of ANRIL SNPs (rs1412830, rs944796, rs61271866, rs2518723, rs3217992), lnc-DC SNPs (rs7217280, rs10515177), MALAT1 SNPs (rs619586, rs4102217, rs591291, rs11227209, rs35138901), ZFAS1 SNPs (rs237742, rs73116127, rs6125607, rs6125608) between RA patients and normal controls (all P > 0.05). The genotype effects of dominant and recessive models were also evaluated, but no significant association was found. In addition, our results demonstrated that the rs944796 G allele, rs2518723 T allele, rs3217992 T allele frequencies were significantly associated with anti-CCP in RA patients (all P < 0.05). The haplotype CGTA frequency for ZFAS1 was significantly higher in RA patients (P = 0.036). Compared with normal controls, the expression levels of ANRIL, lnc-DC, MALAT1, ZFAS1 in PBMCs were significantly reduced in RA patients (all P < 0.001). Moreover, ZFAS1 expression was negatively associated with CRP in RA patients (P = 0.002). In summary, ANRIL, lnc-DC, MALAT1, and ZFAS1 genes SNPs were not associated with RA susceptibility, while altered ANRIL, lnc-DC, MALAT1, ZFAS1 levels in RA patients suggested that these lncRNAs might play a role in RA.

Abstract
PURPOSE Accumulating evidence has linked long noncoding RNAs (lncRNAs) to autoimmune and inflammatory disorders. This study aimed to detect the expression levels of five lncRNAs (lnc0640, lnc3643, lnc5150, lnc7514 and lncagf) in peripheral blood mononuclear cells (PBMCs) of patients with systemic lupus erythematosus (SLE), as well as their correlation with clinical and laboratory features. MATERIALS/METHODS We recruited 76 patients with SLE and 71 normal controls into the present study, and obtained PBMCs from the blood samples of all study subjects. Expression levels of lncRNAs were determined by quantitative real-time reverse transcription polymerase chain reaction and their associations with clinical and laboratory characteristics were analyzed. RESULTS Lnc5150 expression levels were statistically significantly decreased (Z=-6.016, P < 0.001) compared with normal controls. Lnc3643 levels were also statistically significantly decreased in SLE patients with proteinuria compared with those without (Z=-2.934, P = 0.003), and the lnc7514 levels were statistically significantly lower in anti-dsDNA(+) patients compared with anti-dsDNA(-) patients. The expression levels of lnc3643 were correlated with C-reactive protein and erythrocyte sedimentation rate (ESR), lnc7514 was correlated with disease activity and ESR (all P < 0.01). CONCLUSIONS The aberrant lncRNA expression levels and their associations with laboratory features in SLE suggest their important role in SLE pathogenesis.

Abstract
P2X7 receptor (P2X7R), a distinct ligand-gated ion channel, is a member of purinergic type 2 receptor family with ubiquitous expression in human body. Previous studies have revealed a pivotal role of P2X7R in innate and adaptive immunity. Once activated, it will meditate some vital cascaded responses including the assembly of nucleotide-binding domain (NOD) like receptor protein 3 (NLRP3) inflammasome, non-classical secretion of IL-1β, modulation of cytokine-independent pathways in inflammation such as P2X7R- transglutaminase-2 (TG2) and P2X7R-cathepsin pathway, activation and regulation of T cells, etc. In fact, above responses have been identified to be involved in the development of autoimmunity, specifically, the NLRP3 inflammasome could promote inflammation in massive autoimmune diseases and TG2, as well as cathepsin may contribute to joint destruction and degeneration in inflammatory arthritis. Recently, numerous evidences further suggested the significance of P2X7R in the pathogenesis of autoimmune diseases, including systemic lupus erythematosus (SLE), rheumatoid arthritis (RA), inflammatory bowel disease (IBD), multiple sclerosis (MS), etc. In this review, we will succinctly discuss the biological characteristics and summarize the recent progress of the involvement of P2X7R in the development and pathogenesis of autoimmune diseases, as well as its clinical implications and therapeutic potential.

Abstract
OBJECTIVES Anti-keratin antibody (AKA) is a serum antibody for patients with rheumatoid arthritis (RA), and it has a high specificity. Diagnostic role of AKA in RA was evaluated in this study. METHODS PubMed, EMBASE, and Web of Science were searched to acquire eligible studies. Articles published before 15 March 2018 were considered to be included. Quality Assessment of Diagnostic Accuracy Studies 2 was used to evaluate the risk of bias and application concern of the included articles. Pooled analysis of diagnostic indicators of AKA for RA was conducted by using a random effects model. Subgroup analysis was employed to explore the potential influencing factors. RevMan 5.3, Stata 11.0, and Meta-DiSc 1.4 software were used in this study. RESULTS A total of 15 studies (2350 positive and 2067 negative participants) were included. The pooled sensitivity was 0.46 (95% CI 0.44-0.48), pooled specificity was 0.94 (95% CI 0.93-0.95), and pooled diagnostic odds ratio was 15.86 (95% CI 9.48-26.52). In addition, the area under the curve was 0.7194. CONCLUSIONS The current evidence indicated that AKA has high diagnostic specificity in RA and may be useful for RA diagnostic application in clinic.

Abstract
Th17 cell and IL-17-mediated autoimmunity and inflammatory responses have been implicated in the development of organ damage in systemic lupus erythematosus (SLE), and new evidence suggests that hypoxia-inducible factor 1α (HIF-1α) enhances Th17 differentiation and promotes IL-17 production. However, the role of HIF-1α in the pathogenesis of lupus has not been examined. In this study, we silenced HIF-1α in vivo in a murine model of SLE to investigate whether lupus progression and the associated inflammatory pathways were affected by downregulating HIF-1α. Treatment with HIF1α-shRNA suppressed serum IL-17 level in MRL/lpr mice. Decreased anti-nucleosome antibody level, reduced urinary protein concentrations, ameliorated pathological damage, and remarkably reduced renal IgG and C3 depositions were observed in HIF1α-shRNA-treated group compared to those in the controls. Our results provide the first evidence for a role of HIF-1α in the pathogenesis of lupus and suggest a potential new therapeutic avenue for the treatment of lupus patients through reducing the HIF-1α level.

Abstract
OBJECTIVES The aim of our study was to evaluate two lncRNAs (lnc0640 and lnc5150) expressions and gene single-nucleotide polymorphisms (SNPs) in rheumatoid arthritis (RA) patients. METHODS The expressions of lncRNAs in peripheral blood mononuclear cells (PBMCs) were examined by quantitative real-time reverse transcription polymerase chain reaction from 65 RA patients and 54 controls. Simultaneously, three SNPs (rs13039216, rs6085189, and rs6085190) of lnc0640, three SNPs (rs1590666, rs141561256, and rs144047453) of lnc5150 were genotyped using TaqMan SNP-genotyping assays in 627 RA patients and 590 controls. RESULTS The lnc0640 level in PBMCs from RA patients was significantly increased (P = 0.001), whereas the lnc5150 level was significantly reduced (P < 0.001) compared to controls. There were significant associations of lnc0640 and lnc5150 levels with C-reactive protein in RA patients (P = 0.011 and P = 0.014, respectively), while lnc5150 level was associated with erythrocyte sedimentation rate (P = 0.022). TT genotype of rs13039216 in lnc0640 gene was statistically associated with a reduced risk of RA (TT vs CC; P = 0.046), and a decreased risk of rs13039216 variant was observed under the recessive model (P = 0.038). In addition, the G allele of rs141561256 polymorphism in lnc5150 gene was significantly associated with rheumatoid factor in RA patients (P = 0.034). There were no associations between lnc0640 and lnc5150 levels and their respective genotype in RA patients. CONCLUSIONS The expressions of lnc0640 and lnc5150 were alternated in the RA patients, suggesting that these lncRNAs may involve in the development of RA.

Abstract
This study was conducted to (1) characterize coagulation cascade and complement system in systemic lupus erythematosus (SLE); (2) evaluate the associations between coagulation cascade, complement system, inflammatory response and SLE disease severity; (3) test the diagnostic value of a combination of D-dimer and C4 for lupus activity. Transcriptomics, proteomics and metabolomics were performed in 24 SLE patients and 24 healthy controls. The levels of ten coagulations, seven complements and three cytokines were measured in 112 SLE patients. Clinical data were collected from 2025 SLE patients. The analysis of multi-omics data revealed the common links for the components of coagulation cascade and complement system. The results of ELISA showed coagulation cascade and complement system had an interaction effect on SLE disease severity, this effect was pronounced among patients with excess inflammation. The analysis of clinical data revealed a combination of D-dimer and C4 provided good diagnostic performance for lupus activity. This study suggested that coagulation cascade and complement system become 'partners in crime', contributing to SLE disease severity and identified the diagnostic value of D-dimer combined with C4for lupus activity.

Abstract
Clinical toxoplasmosis in AIDS/HIV patients is a great public health concern around the world. Untreated Toxoplasma gondii (T. gondii)-infections are often fatal in AIDS/HIV patients. This study aims to assess the seroprevalence and odds ratio (OR) of T. gondii in AIDS/HIV patients, as well as the potential influential factors. Studies published from December 1, 1983 to December 1, 2016 in English, which comparing the seroprevalence of T. gondii between AIDS/HIV patients and control group were searched in PubMed, EMBASE and The Cochrane Library databases. The non-weighted prevalence, pooled fixed-effect or random-effect model estimates of OR and its 95% confidence intervals (CI) were all calculated. Heterogeneity test was performed by the Q statistic and quantified using I2, publication bias was evaluated using a funnel plot and Egger's linear regression test. A total of 4220 articles were obtained after searching databases, and 12 studies with 2101 AIDS/HIV patients and 5851 controls were incorporated in the meta-analysis. Meta-analysis revealed that, compared with the control group, the AIDS/HIV group had a higher seroprevalence of T. gondii (46.12% vs 36.56%) (OR=1.55, 95%CI: 1.19-2.04). Subgroup analyses showed that publication year, race, geographic locations and diagnostic methods are positive associated with the seroprevalence of T. gondii. Overall, our study suggests that AIDS/HIV patients have higher seroprevalence of T. gondii than those without.

The aim of this study was to investigate the association of interleukin (IL)-10 gene single nucleotide polymorphisms (SNPs) with susceptibility to systemic lupus erythematosus (SLE) in a Chinese population. 848 SLE patients and 461 normal controls were recruited in this study. Nine SNPs in IL-10 gene (rs1518110, rs1518111, rs1554286, rs1800890, rs1800893, rs3024493, rs3024495, rs3024498 and rs6667202) were genotyped using TaqMan genotyping assays on Fluidigm 192.24 system. The frequency of IL-10 rs3024498-C allele was significantly higher in patient group compared with control subjects (OR=5.118, 95% CI=1.819-14.405, P=0.002). No significant differences were detected for the distribution of allele and genotype frequencies of other eight SNPs between patients with SLE and controls after Bonferroni correction (all P>0.0056). Interestingly, significant differences were detected both in the allele and genotype frequencies of rs3024498 between SLE patients with and without arthritis (P=0.002, P=0.022, respectively).There was significant difference in genotype frequency at rs3024498 between SLE patients with and without malar rash (P=0.040). And, there was significant difference in allele frequency at rs3024498 between SLE patients with and without anti-double-stranded DNA (P=0.032). Meanwhile, significant difference in genotype frequency at rs1518110 and rs1518111 were found in patients with and without lupus headache (P=0.025, P=0.038, respectively). There were significant difference in allele and genotype frequency at rs1800890 and rs6667202 between SLE patients with and without thrombocytopenia (rs1800890: P=0.016, P=0.026, respectively; rs6667202: P=0.007, P=0.007, respectively). Further, significant difference were observed both in allele frequency and in genotype distribution of rs1800893 between patients with and without tubular urine and proteinuria (tubular urine: P<0.001, P=0.003, respectively; proteinuria: P=0.001, P=0.018, respectively). In summary, IL-10 rs3024498 polymorphism might contribute to SLE susceptibility and several clinical phenotypes.

Abstract
The field of m6A modification and epitranscriptomics has recently attracted much attention. More methods allowing for precise m6A site profiling and location are developed and crucial players of m6A modification machinery are increasingly identified. Although some challenges remain, m6A modification is found to modulate almost all aspects of RNA metabolism, such as splicing, stability, structure, translation, and export. Thus, m6A modification adds a new layer of post-transcriptional gene expression regulation, and it is implicated in T cell response to HIV infection, type I interferon production, and T cell differentiation and homeostasis. Moreover, evidence supporting its involvement in various human diseases including cancers is accumulating. Given the role of m6A modification in gene expression regulation and immune response, it invites the speculation that m6A modification may justify the pathogenesis of systemic lupus erythematosus (SLE) and take part in the initiation and progression of SLE. In this review, we introduce the widespread existence of m6A modification and briefly discuss components of m6A modification machinery in mammals. We mainly summarize the studies reporting the mechanisms of m6A modification in gene expression regulation through modulating pre-mRNA splicing, mRNA stability, RNA structure, translation, and pri-miRNA processing. Biological functions related to immune response of m6A modification and the implication of m6A modification in cancers are highlighted. In the end, we surmise the potential link between m6A modification and SLE.

Abstract
Mammalian genome is pervasively transcribed, producing large number of noncoding RNAs (ncRNAs), including long noncoding RNAs (lncRNAs), primary miRNAs (pri-miRNA), and circular RNAs (circRNAs). The translation of these ncRNAs has long been overlooked. Increasing studies, however, based on ribosome profiling in various organisms provide important clues to unanticipated translation potential of lncRNAs. Moreover, a few functional peptides encoded by lncRNAs and pri-miRNAs underline the significance of their translation. Recently, several novel researches also evidence the translation of endogenous circRNAs. Given the functional significance exemplified by peptides translated by some ncRNAs and their pervasive translation, it is not too far-fetched to image that abnormal translation of ncRNAs may contribute to human diseases. Through challenging, deciphering ncRNA translation is required for comprehensive understanding of biology and medicine. In this review, we firstly present evidence concerning translation potential of lncRNAs and go on to introduce a few functional short peptides encoded by lncRNAs. Then, salient observations showing translation of pri-miRNAs and circRNAs are described in detail. We end by discussing the impact of ncRNA translation beyond producing peptides and referring briefly to the potential role of abnormal ncRNA translation in human diseases.

Abstract
The aims of the present study were to determine whether the changes in density and location of CD68-positive and CD206-positive macrophages contribute to progression of hepatocellular carcinoma (HCC) and to evaluate prognostic values of these cells in post-surgical patients. A retrospective study involving 268 HCC patients was conducted. CD68-positive and CD206-positive macrophage infiltration in HCC tissues and adjacent tissues was examined by immunohistochemistry (IHC) and the relationship between the clinicopathological features and prognosis was analyzed. Receiver operating characteristics (ROC) curve was used to calculate diagnostic accuracy. There was an increase in CD68-positive and CD206-positive macrophage infiltration in adjacent tumor tissues compared with tumor tissues. ROC curve identified their optimal diagnostic cut-off values. The survival analysis showed that increased CD68 expression in adjacent tissues conferred superior overall survival (OS) and disease-free survival (DFS), while increase of CD206 in tumor yielded inferior OS and DFS. Cox regression analysis suggested both CD68-positive macrophages in adjacent area and intratumor CD206-positive macrophages as independent prognostic biomarkers for post-surgical HCC patients. Finally, a combination of CD68/CD206 and HBV-positive further improved prognostic stratification, especially in DFS. These results provide the first evidence for region- and subset-dependent involvement of CD68 and CD206 cells in HCC progression. A combination of CD68/CD206 density and HBV-positivity improves further predictive value for post-operative recurrence of HCC. Quantification of CD68/CD206 macrophages and their distribution can be exploited for better postsurgical management of HCC patients. These findings provide a basis for developing novel treatment strategies aimed at re-educating macrophages in tumor microenvironment.

Abstract
Long non-coding RNAs can regulate gene transcription, modulate protein function, and act as competing endogenous RNA. Yet, their roles in systemic lupus erythematosus remain to be elucidated. We determined the expression profiles of lncRNAs in T cells of SLE patients and healthy controls using microarrays. Up to 1935 lncRNAs and 1977 mRNAs were differentially expressed. QRT-PCR showed downregulated uc001ykl.1 and ENST00000448942 in SLE patients. Expression of uc001ykl.1 correlated with erythrocyte sedimentation rate (ESR) and C-reactive protein, whereas ENST00000448942 level correlated with ESR and anti-Sm antibodies. Short time-series expression miner analysis revealed some lncRNAs whose expressions might correlate with disease activity of SLE patients. Coding-non-coding gene coexpression analyses showed differential lncRNAs might operate via modulating expressions of their correlated, relevant mRNAs in SLE. Differential lncRNAs might also function through their ceRNAs. Our study established that the aberrant expression profiles of lncRNAs may play a role in SLE and thus warrant further investigation.

Abstract
INTRODUCTION MicroRNAs (miRNAs) are a set of small single-stranded noncoding RNAs with diverse biological functions. As a prototypical hypoxamir, human microRNA-210 (hsa-miR-210) is one of the most widely studied miRNAs thus far. In addition to its involvement in sophisticated regulation of numerous biological processes, miR-210 has also been shown to be associated with the development of different human diseases including various types of cancers, cardiovascular and cerebrovascular diseases, and immunological diseases. Given its multi-faceted functions, miR-210 may serve as a novel and promising theranostic target for prevention and treatment of diseases. Areas covered: This review aims to provide a comprehensive overview of miR-210, the regulation of its expression, biological functions and molecular mechanisms, with particular emphasis on its diagnostic and therapeutic potential. Expert opinion: Although the exact roles of miR-210 in various diseases have not been fully clarified, targeting miR-210 may be a promising therapeutic strategy. Further investigations are also needed to facilitate therapeutic-clinical applications of miR-210 in human diseases.

Abstract
We evaluated the differences in major markers of cardiovascular (CV) risk between inflammatory bowel diseases (IBDs) and controls by a systematic review and a meta-analysis. We searched PubMed, EMBASE, and Cochrane databases for literature comparing CV risk markers in IBDs and controls. The overall mean carotid intima-media thickness (CIMT), flow-mediated dilation (FMD%), and carotid-femoral pulse wave velocity (cfPWV) difference between patients with IBDs and control groups were calculated. Twenty-eight studies were included in the meta-analysis, including 16 studies with data on CIMT, 7 studies reporting FMD%, and 9 studies on cfPWV. Compared to controls, patients with IBDs showed significantly higher CIMT (standardized mean difference [ SMD]: 0.534 mm; 95% confidence interval [CI], 0.230 to 0.838; P = .001), significantly lower FMD% ( SMD, -0.721%; 95% CI, -1.020 to -0.421; P < .0001), and significantly increased cfPWV ( SMD, 0.849; 95% CI, 0.589 to 1.110; P < .0001). When analyzing subgroups with ulcerative colitis and Crohn disease (CD), all results were still significant except CIMT in CD. Our findings support the current evidence for an elevated CV burden in patients with IBD and support the clinical utility of markers of subclinical atherosclerosis in the management of these patients.

Abstract
The objective of this study was to use RNA interference (RNAi) to improve protein quality and decrease anti-nutritional effects in soybean. Agrobacterium tumefaciens-mediated transformation was conducted using RNAi and an expression vector containing the 7S globulin β-subunit gene. The BAR gene was used as the selective marker and cotyledonary nodes of soybean genotype Jinong 27 were chosen as explant material. Regenerated plants were detected by molecular biology techniques. Transformation of the β-subunit gene in the 7S protein was detected by PCR, Southern blot, and q-PCR. Positive plants (10 T0, and 6 T1, and 13 T2) were tested by PCR. Hybridization bands were detected by Southern blot analysis in two of the T1 transgenic plants. RNAi expression vectors containing the soybean 7S protein β-subunit gene were successfully integrated into the genome of transgenic plants. qRT-PCR analysis in soybean seeds showed a clear decrease in expression of the soybean β-subunit gene. The level of 7S protein β-subunit expression in transgenic plants decreased by 77.5% as compared to that of the wild-type plants. This study has established a basis for the application of RNAi to improve the anti-nutritional effects of soybean.

Abstract
OBJECTIVES Recent evidence has demonstrated that CD3ζ (also called CD247) play a vital role in multiple autoimmune diseases. In this study, we explored the association between CD247 gene single-nucleotide polymorphisms (SNPs) and rheumatoid arthritis (RA) in a Chinese Han population. We also evaluated the CD3ζ expression profile in peripheral blood mononuclear cells (PBMCs) from patients with RA and health controls. METHODS Three CD247 polymorphisms (rs704853, rs1214611 and rs858554) were studied in 612 patients with RA and 848 controls in a Chinese population. Genotyping was performed using the Fluidigm 192.24 Dynamic Array™ Integrated Fluidic Circuit (IFC). For gene expression study, CD3ζ mRNA levels of 36 patients with RA and 39 healthy individuals were assessed by real-time polymerase chain reaction (RT-PCR). Data were analyzed by SPSS 11.5 software. RESULTS A significant association between rs858554 polymorphism and RA was found under all genetic models (all p < 0.05). Moreover, we found the genotype distribution and allele frequency of rs858554 were significant associated with ACCP+ and RF+ phenotype as compare to health controls (all p < 0.05). Unfortunately, we did not detect any significant associations between rs704853, rs1214611 and RA susceptibility and autoantibody profiles (all p > 0.05). The gene expression assays showed that CD3ζ mRNA levels were downregulated in PBMCs of patients with RA when compared to healthy controls. CONCLUSIONS Our results, the first reported for distinct Chinese populations, support a role of the CD247 gene in the susceptibility to RA. Further studies with more sample size are necessary to clarify the exact role of CD247 gene in the pathogenesis of RA.

Abstract
The objective of this study was to investigate the prevalence and influencing factors of HIV infection among men who have sex with men (MSM) in Hefei, China. A total of 578 MSM were recruited, with a mean age of 28.13 ± 6.91; 70.7% were under 30. The awareness rate was 95.4% (560/587) in the cross-sectional study. Of all the respondents, 73 (12.44%) were seropositive for HIV and 56 (9.54%) for syphilis. Multivariate analysis showed that self-reported sexually transmitted infections (STIs) (AOR = 8.02, 95% CI: 2.58-24.98, P < 0.001), received HIV testing in the past year (AOR = 0.33, 95% CI: 0.19-0.60, P < 0.001) and syphilis (AOR = 3.40, 95% CI: 1.69- 6.85, P = 0.001) were independently associated with HIV infection. It is necessary for post-test counselling to address risk among those who engage in sexual risk behaviours. More efforts are needed to enhance HIV/STI testing and treatment services in China.

Abstract
While highly active antiretroviral therapy has been successful in delaying progression into AIDS, late HIV diagnosis remains a major contributor to the mortality and morbidity of AIDS. An epidemiological study was conducted to evaluate the prevalence and factors of late diagnosis and the characteristics of those individuals with late diagnosis in Liuzhou city. Patients with late diagnosis were defined as either those who were diagnosed with AIDS at the time of HIV diagnosis or as those who developed AIDS no more than 1 year after HIV diagnosis. Of 899 participants, 72.6% had a late diagnosis. Common characteristics of those who experienced late diagnosis included older participants, those who were unexpectedly diagnosed while seeking other medical attention, participants who believed they could not acquire HIV from their regular heterosexual partners, those who never considered getting tested for HIV, and patients with unexplained weight loss, angular cheilitis, or prolonged fever prior to HIV diagnosis. On the other hand, those participants who were diagnosed via testing at compulsory rehabilitation centers and those whose annual household income was greater than 30,000 Yuan were less likely to be diagnosed late. These results suggested that late HIV diagnosis is common in Liuzhou city, and it is essential to promote appropriate strategies to detect HIV infections earlier. Strategies that require HIV/AIDS patients to notify their spouse/sexual-partners about their HIV-positive results within one month and start provider-initiated HIV testing and counseling in medical facilities are beneficial to earlier HIV diagnosis.

Abstract
To evaluate the incidence and risk factors for human immunodeficiency virus (HIV) seroconversion of HIV-negative partners among HIV-discordant couples in Liuzhou, China, 1854 eligible HIV-serodiscordant couples were retrospectively identified through the HIV epidemiology and follow-up database from January 1, 1996 to June 30, 2013. Cox proportional-hazards model was used to examine risk factors related to HIV seroconversion of negative partners. Finally, 125 HIV seroconversion occurred over 4963.5 person-years, resulting in an overall HIV incidence of 2.52/100 person-years. HIV-positive partners with the last CD4 counts of 350 cells/ul or more were significantly protected against HIV seroconversion compared with those CD4 counts of less than 200 cells/ul (aHR = 0.46, 95% CI: 0.27-0.81, P < 0.01). Men with HIV-positive wives (aHR: 1.96, 95% CI: 1.27-3.02, P < 0.01), HIV-positive partners who did not receive ART before their HIV-negative partners' seroconversion (aHR: 2.22, 95% CI, 1.41-3.51, P < 0.01) and patients reported intermittent condom use (aHR: 7.60, 95% CI, 4.37-13.21, P < 0.01) were associated with increased risk of HIV seroconversion. HIV-negative partners remain high risk of HIV infection in Liuzhou city. Comprehensive package of HIV prevention services should contribute to reduction in HIV transmission of discordant couples.

Abstract
OBJECTIVE To determine the prevalence of infections with HIV and hepatitis C virus (HCV), and of syphilis among female sex workers (FSWs) in Liuzhou, China, along with levels of HIV-related knowledge and frequencies of risk behaviors. METHODS A cross-sectional survey was conducted between July 2012 and January 2013. FSWs (aged ≥16 years; reported receiving payment for sex in previous 6 months) working at 58 selected commercial sex establishments (level 1 [>¥300 per transaction], level 2 [¥100-300], or level 3 [<¥100]) completed a questionnaire and provided blood samples for testing. RESULTS Of 622 participating FSWs, 7 (1.1%) had HIV infection, 67 (10.8%) syphilis, and 44 (7.1%) HCV infection. Consistent condom use during commercial sex encounters in the past month was reported by 412 (66.2%) FSWs. Inconsistent condom use was most likely in FSWs working in level 3 establishments (odds ratio [OR] 1.85; 95% CI 1.02-3.39), with a regular partner (OR 1.65; 95% CI 1.12-2.45), and who used illicit drugs (OR 2.10; 95% CI 1.24-3.54). Inconsistent condom use was least likely in FSWs with high HIV awareness (OR 0.29; 95% CI 0.18-0.48) and who had had a previous HIV test (OR 0.51; 95% CI 0.34-0.76). CONCLUSION Further prioritized and combined programs aimed at FSWs are needed to prevent HIV transmission in China.

Abstract
OBJECTIVE The aim to this study was to investigate the association between the single-nucleotide polymorphisms (SNPs) of interleukin (IL)-23 receptor gene and systemic lupus erythematosus (SLE) in a Chinese population. METHODS A case-control study was performed to investigate the associations of SNPs in IL-23R gene (rs10889677 and rs1884444) with susceptibility to SLE in 521 Chinese SLE patients and 527 normal controls. The chi-square test and unconditional Logistic regression were used to analysis by SPSS 10.1 software. RESULTS No significant differences were detected for the distribution of allele and genotype frequencies of these two SNPs between patients and controls as well as SLE patients with nephritis (LN) and those without nephritis. CONCLUSION The findings suggest that the polymorphisms of IL-23R gene might not contribute to the susceptibility of SLE in the Chinese population.

Abstract
Many epidemiological studies have investigated IL1α and IL1β polymorphisms with SLE risk, but no conclusions are available because of conflicting results. This meta-analysis was performed to more precisely estimate the relationships. The databases of PubMed updated to September 1st, 2012 were retrieved. Odds ratio (OR) and corresponding 95% confidence interval (95% CI) as effect size were calculated by a fixed- or random-effect model. In total, six case-control studies for IL1β-511C/T, four studies for IL1β+3953C/T, three studies for IL1α-889C/T and three studies for IL1α+4845G/T were involved in this analysis. The results indicated that for IL1α-889C/T polymorphism T allele was associated with decreased risk of SLE (OR (95% CI)) (T vs. C: 0.802 (0.679-0.949); TT+CT vs. CC: 0.615 (0.380-0.995); TT vs. CC: 0.679 (0.466-0.989)). However, when analysis for TT vs. CT+CC was conducted, the result indicated that IL1α-889C/T polymorphism was not associated with SLE (OR (95% CI): 0.847 (0.595-1.205)). Combined analysis indicated that IL1β-511C/T polymorphism was not overall associated with risk of SLE (OR (95% CI)) (T vs. C: 1.113 (0.954-1.298); TT vs. CT+CC: 1.146 (0.889-1.447); TT+CT vs. CC: 1.145 (0.903-1.452); TT vs. CC: 1.255 (0.928-1.698)). When subgroup analysis for Asian ethnicity was conducted, the results indicated that IL1β-511C/T polymorphism was associated with SLE only for TT vs. CT+CC (OR (95% CI): 1.468 (1.001-2.152)), but was not associated for T vs. C (OR (95% CI): 1.214 (0.955-1.544)), TT+CT vs. CC (OR (95% CI): 1.112 (0.765-1.615)) and TT vs.CC (OR (95% CI): 1.411 (0.896-2.222)). In addition, overall analyses indicated that IL1β+3953C/T and IL1α+4845G/C polymorphisms were also not associated with risk of SLE (OR (95% CI)) (for IL1β+3953C/T T vs. C: 0.996 (0.610-1.626), TT vs. CT+CC: 0.658 (0.318-1.358), TT+CT vs. CC: 1.021 (0.618-1.687), TT vs. CC: 0.640 (0.309-1.325); for IL1α+4845G/T T vs. G: 1.067 (0.791-1.440), TT+GT vs. GG: 0.934 (0.646-1.351)).This study inferred that IL1α-889C/T polymorphism might be moderately associated with SLE, but no sufficient evidence was available to support any associations between IL1β+3953C/T or IL1α+4845G/C polymorphisms and SLE. We could not draw a definite conclusion between IL1β-511C/T polymorphism and risk of SLE owing to the limited data. Further large sample-sized studies should be required.

Abstract
This study aims to investigate the serum IL-21 levels in systemic lupus erythematosus (SLE) and its relations with clinical and laboratory features. Fifty-seven patients with SLE and 30 healthy volunteers were recruited in the current study. Serum IL-21 levels were detected by enzyme-linked immunosorbent assay. Statistical analyses were performed by SPSS 10.01. Results showed that IL-21 levels were significantly decreased in the serum of patients with SLE compared with controls (P = 0.026). There was no significant difference regarding serum IL-21 level between SLE patients with nephritis and those without nephritis (P = 0.066); no significant difference was found between less active SLE and more active SLE (P = 0.588). The presence of anemia was associated with low serum IL-21 levels (P = 0.030) in SLE patients. In summary, decreased serum level of IL-21 and its association with anemia indicate a possible role of IL-21 in human SLE. However, further studies are needed to confirm this preliminary results.
