Abstract
Background:Pain is a dominant symptom of psoriatic arthritis (PsA), and pain reduction is a priority for patients (pts) that is often assessed in clinical trials. Upadacitinib (UPA), a Janus kinase (JAK) inhibitor engineered for increased selectivity for JAK1 over JAK2, JAK3, and tyrosine kinase2, has demonstrated safety and efficacy in pts with active PsA in the SELECT-PsA 1 and 2 studies.1,2Objectives:The objective of this analysis was to compare the efficacy of UPA vs placebo (PBO) and adalimumab (ADA) on pain using different assessments through 24 weeks (wks).Methods:The SELECT-PsA program enrolled adult pts with active PsA with prior inadequate response (IR) or intolerance to ≥1 non-biologic DMARD (SELECT-PsA 1; NCT03104400) or prior IR or intolerance to ≥1 biologic DMARD (SELECT-PsA 2; NCT03104374). Concomitant background therapy with ≤2 non-biologic DMARDs was allowed but not required. Pts were randomized to UPA 15 mg or UPA 30 mg once daily (QD) or PBO (both studies), or ADA 40 mg every other week (EOW; SELECT-PsA 1 only). Pain was assessed as proportion of pts achieving ≥30%, ≥50%, or ≥70% reduction from baseline (BL) in Pt’s global assessment (PGA) of pain numeric rating scale (NRS) score (0–10), proportion of pts achieving minimal clinically important difference (MCID) in pain (defined as ≥1 point reduction or 15% reduction from BL on a 0–10 NRS)3,4 and change from baseline in pain NRS (0–10) at all time points. In addition, change from BL in BASDAI questions 2 (spinal pain) and 3 (joint pain/swelling) and 36-Item Short Form Survey (SF-36) questions 7 (bodily pain) and 8 (pain interference) at weeks 12 and 24 were assessed. Non-responder imputation was used for binary endpoints and mixed-effects model for repeated measurements for continuous endpoints. The statistical significance defined as P<0.05 was exploratory in nature.Results:In both studies, a significantly higher proportion of pts receiving UPA 15 mg QD and UPA 30 mg QD vs PBO achieved improvements in most pain endpoints as early as wk 2, and improvements were generally either sustained or increased through wk 24 (nominal P<0.05). A significant improvement with UPA vs PBO was also observed for change from BL in PGA of pain NRS scores over time, as well as in BASDAI spinal pain and joint pain/swelling and SF-36 bodily pain and pain interference at weeks 12 and 24. In SELECT-PsA 1 significantly higher proportions of pts receiving UPA 30 mg QD vs ADA 40 mg EOW achieved improvements in most pain assessments as early as wk 2 which were sustained through wk 24; improvements in several assessments were also significantly greater with UPA 15 mg QD vs ADA 40 mg EOW at wk 24 (nominal P <0.05; Data will be presented).Conclusion:In pts with active PsA who had inadequate response to non-biologic or biologic DMARDs, a greater proportion of pts treated with UPA vs PBO achieved rapid, significant, and clinically meaningful reductions in pain across multiple pain assessments. The reductions in pain were sustained over 24 wks.References:[1]McInnes I. et al. Ann Rheum Dis. 2020;79(Suppl 1):12-13.[2]Genovese M.C. et al.

Abstract
Background:For patients (pts) with PsA, several disease activity measures are available including very low/minimal disease activity (VLDA/MDA), cutoffs based on the Disease Activity in PsA (DAPSA) score, and on the Psoriatic Arthritis Disease Activity Score (PASDAS) score.Objectives:To assess the rates of pts achieving these remission or low disease activity (LDA) criteria at Wk 24 using data from the SELECT-PsA 1 and SELECT-PsA 2 phase 3 studies;1,2 Additionally, we assessed the distribution of individual MDA components among pts who did or did not achieve MDA criteria at Wk 24.Methods:In SELECT-PsA 1 and SELECT-PsA 2, pts with PsA and prior inadequate response (IR) or intolerance to ≥1 non-biologic DMARD (N=1705) or ≥1 biologic DMARD (N=642), respectively, were randomized to once daily upadacitinib (UPA) 15mg, UPA 30mg, adalimumab (ADA) 40mg every other week (SELECT-PsA 1 only), or placebo (PBO). Remission and LDA were assessed using VLDA/MDA, DAPSA scores of ≤4/≤14, and PASDAS scores of ≤1.9/≤3.2, at Wk 24 (Table 1). Non-responder imputation (NRI) was used for handling missing data; pts rescued at Wk 16 were considered non-responders. Pairwise comparisons between UPA doses and PBO or ADA were conducted using the Cochran-Mantel-Haenszel test.Results:Overall, 2345 pts were analyzed; mean age 51 years, 53% female. In both studies, higher rates of remission and LDA were observed with both UPA doses vs PBO at Wk 24 (nominal P-values <0.05 for both time points; Table 1). Generally, higher rates of remission and LDA were also observed with UPA30 vs ADA in non-biologic DMARD-IR pts (nominal P-values <0.05). Greater rates of MDA/VLDA were observed at Wk 24 with UPA15 and UPA30 vs PBO in both studies and with UPA30 vs ADA in non-biologic DMARD-IR pts (nominal P-values <0.05 for all comparisons). The proportion of responder or non-responder pts receiving UPA15 or UPA30 was similar for each of the MDA components in both studies. At Wk 24, more responder and non-responder pts in both studies achieved Swollen Joint Count (SJC) 66 ≤1, Psoriasis Area and Severity Index (PASI) ≤1 or Body Surface Area-Psoriasis (BSA-Ps) ≤3%, and Leeds Enthesitis Index (LEI) ≤1 (Figure 1). Conversely, the proportion of pts Achieving Tender Joint Count (TJC) 68 ≤1 and Pt’s Global Assessment of Pain ≤1.5 tended to be lower.Conclusion:Regardless of previous biologic DMARD failure, pts treated with UPA15 or UPA30 achieved a higher rate of remission or LDA measured by various disease activity measures vs PBO at Wk 24; higher rates of response were observed in most of the remission and LDA measures with UPA30 vs ADA in non-biologic DMARD-IR pts. Among pts who did or did not achieve MDA criteria at Wk 24, a greater proportion of UPA-treated pts achieved physician derived measures such as SJC ≤1, PASI ≤1 or BSA-Ps ≤3%, and LEI ≤1.References:[1]McInnes IB, et al.

Abstract
Background:Although most patients with psoriatic arthritis (PsA) enrolled in clinical trials have polyarticular arthritis, patients in clinical practice may present with oligoarthritis. Data on the efficacy of Janus kinase inhibitors in patients with PsA with low joint counts are limited.Objectives:To evaluate the efficacy of upadacitinib (UPA) in subgroups of patients with PsA with a low (baseline swollen joint count [SJC] <5) or high (SJC ≥5) SJC (LSJ or HSJ).Methods:Data were pooled across the SELECT-PsA 11 (non-biologic disease-modifying antirheumatic drug [non-bDMARD] inadequate response [IR] or intolerance) and SELECT-PsA 22 (bDMARD IR or intolerance) trials, which both enrolled patients with ≥3 involved joints (SJC ≥3 and tender joint count [TJC] ≥3). Subgroup analysis was performed for patients with LSJ or HSJ treated with UPA 15 mg once daily (QD) or placebo (PBO). Efficacy endpoints included minimal disease activity (MDA), very low disease activity (VLDA), Psoriatic Arthritis Disease Activity Score (PASDAS) low disease activity (LDA; ≤3.2), PASDAS remission (≤1.9), and 20/50/70% improvement in American College of Rheumatology (ACR) criteria (ACR20/50/70), all at Week 24, and Psoriasis Area Severity Index (PASI) 75 and static Investigator Global Assessment of Psoriasis (sIGA) 0/1 at Week 16.Results:At baseline, patients with HSJ (n=1060) had similar demographic characteristics but tended to have higher overall disease activity than patients with LSJ across multiple disease domains (n=215; Table 1). UPA efficacy appeared comparable in patients with LSJ and HSJ, with similar proportions of patients achieving composite (MDA, VLDA, PASDAS LDA, and PASDAS remission) measures at Week 24, and skin endpoints (PASI 75 and sIGA 0/1) at Week 16 (Figure 1). At Week 24, 60.0/36.8/22.1% of patients with LSJ receiving UPA 15 mg achieved ACR20/50/70 vs 40.0/17.5/5.8% in the PBO group; rates were 70.3/49.7/26.2% (UPA 15 mg) and 36.1/15.3/3.3% (PBO) in those with HSJ.Table 1.Baseline characteristicsPBOUPA 15 mg QDTotalLSJn=120HSJn=515LSJn=95HSJn=545LSJn=215HSJn=1060Female, n (%)65 (54.2)266 (51.7)49 (51.6)302 (55.4)114 (53.0)568 (53.6)Age (years), mean (SD)52.2 (12.7)51.5 (12.0)52.0 (10.6)52.0 (12.4)52.1 (11.8)51.8 (12.2)Duration since PsA symptoms (years), mean (SD)10.5 (9.2)11.1 (10.2)9.8 (8.2)10.3 (8.9)10.2 (8.7)10.7 (9.6)BMI, mean (SD)29.7 (6.3)31.1 (7.2)29.8 (6.2)30.7 (6.9)29.7 (6.2)30.9 (7.0)Prior failed bDMARDs, n (%)03 (2.5)15 (2.9)1 (1.1)15 (2.8)4 (1.9)30 (2.8)122 (18.3)113 (21.9)22 (23.2)104 (19.1)44 (20.5)217 (20.5)24 (3.3)31 (6.0)7 (7.4)28 (5.1)11 (5.1)59 (5.6)≥34 (3.3)20 (3.9)7 (7.4)27 (5.0)11 (5.1)47 (4.4)Use of ≥1 non-bDMARD atbaseline, n (%)87 (72.5)360 (69.9)63 (66.3)388 (71.2)150 (69.8)748 (70.6)Dactylitis (LDI >0), n (%)21 (17.5)169 (32.8)15 (15.8)176 (32.3)36 (16.7)345 (32.5)Enthesitis (LEI >0), n (%)60 (50.0)325 (63.1)60 (63.2)343 (62.9)120 (55.8)668 (63.0)TJC68, mean (SD)12.5 (11.3)23.9 (15.8)14.6 (13.5)23.1 (15.8)13.4 (12.3)23.5 (15.8)SJC66, mean (SD)3.5 (0.5)13.2 (8.3)3.6 (0.5)12.9 (9.0)3.6 (0.5)13.0 (8.7)HAQ-DI, mean (SD)1.0 (0.6)1.2 (0.7)0.9 (0.6)1.2 (0.6)0.9 (0.6)1.2 (0.7)hs-CRP > ULN (mg/L), n (%)82 (68.3)363 (70.5)62 (65.3)388 (71.2)144 (67.0)751 (70.8)BSA-Ps, median (range)3.0 (0.1–70.0)4.0 (0.1–95.0)2.0 (0.1–80.0)3.0 (0.1–97.0)3.0 (0.1–80.0)3.0 (0.1–97.0)BSA-Ps ≥ 3%, n (%)57 (47.5)285 (55.3)44 (46.3)300 (55.0)101 (47.0)585 (55.2)PASI (baseline BSA-Ps ≥ 3%), mean (SD)7.7 (7.5)12.1 (11.9)8.2 (7.0)10.2 (10.0)7.9 (7.2)11.1 (11.0)PASI (baseline BSA-Ps ≥ 3%), median (range)5.3 (0.1–39.4)7.9 (0.3–64.8)6.5 (0.2–35.4)6.8 (0.1–70.8)6.0 (0.1–39.4)7.3 (0.1–70.8)Conclusion:UPA efficacy was generally similar in patients with PsA with LSJ or HSJ, with both patient groups showing improvements in composite clinical endpoints and skin responses vs PBO.References:[1]McInnes I, et al.

Abstract
Background:Upadacitinib (UPA) has shown efficacy and safety in patients (pts) with active PsA in the Phase 3 SELECT-PsA 1 and SELECT-PsA 2 clinical trials.1,2 Historically efficacy has been lower with second- and third-line therapy compared with first-line anti-TNF therapy in PsA;3,4 however, clinical trial data that describe efficacy in pts who have had an inadequate response (IR) to multiple biologic DMARDs (bDMARDs) are limited.Objectives:This analysis assessed the effects of prior bDMARD failure on UPA efficacy in the SELECT-PsA 2 trial.Methods:The SELECT-PsA 2 study enrolled pts with prior IR or intolerance to ≥1 bDMARD (N=642). Pts were randomized to placebo (PBO), UPA 15 mg once daily (QD, UPA15), or UPA 30 mg QD (UPA30). Stable background treatment of ≤2 non-bDMARDs was permitted; background therapy was not required. Only the pts who had IR to ≥1 bDMARD were included in this analysis; pts were subgrouped based on the number of bDMARDs failed prior to enrollment (1, 2, or ≥3). This analysis includes assessment of proportion of pts achieving ACR20/50/70, and change in HAQ-DI, FACIT-Fatigue, and SF-36 Physical Component Summary at Wk 12; static Investigator Global Assessment of Psoriasis of 0 or 1 and at least a 2-point improvement from baseline, PASI75, and change in Self-Assessment of Psoriasis Symptoms at Wk 16; and proportion of pts achieving minimal disease activity (MDA) at Wk 24. Non-responder imputation was used for binary endpoints. Mixed-effects model for repeated measures was used for continuous endpoints. Point estimates and 95% confidence intervals (CIs) of the PBO subtracted treatment effect were calculated.Results:641 pts were randomized and received study drug; 92% were bDMARD-IR: 391 (61%) of pts failed 1 bDMARD, 116 (18%) failed 2 bDMARDs, and 83 (13%) failed ≥3 bDMARDs. In the overall study population, UPA15 and UPA30 demonstrated superiority vs placebo for all endpoints evaluated. In this post hoc analysis, the PBO subtracted treatment effect demonstrates generally consistent efficacy as compared to the overall study population for UPA15 and UPA30 across efficacy endpoints in the subgroups of pts with IR to 1, 2, or ≥3 prior bDMARDs (Figure 1). Due to limited sample sizes for pts with IR to >1 bDMARD and the pt subsets analyzed for psoriasis-related endpoints, results should be interpreted with caution.Conclusion:Upadacitinib demonstrated consistent efficacy in treating clinical manifestations of PsA including musculoskeletal symptoms, psoriasis, physical function, fatigue, and quality of life in pts with IR to 1 or multiple prior bDMARDs. In addition, comprehensive disease control as measured by MDA, was generally consistently achieved with upadacitinib regardless of number of prior bDMARDs tried.References:[1]McInnes IB, et al.

Abstract
Background:Approximately 40% of PsA patients (pts) on advanced therapy are on monotherapy.1,2 Upadacitinib (UPA) showed efficacy and safety in pts with active PsA in the Phase 3 SELECT-PsA 1 and SELECT-PsA 2 clinical trials.3,4Objectives:Assess efficacy and safety in subgroups of pts treated with UPA as monotherapy or in combination with non-biologic disease-modifying antirheumatic drugs (non-bDMARDs).Methods:The SELECT-PsA program enrolled pts with prior inadequate response (IR) or intolerance to ≥1 non-bDMARD (N=1705) and prior IR or intolerance to ≥1 bDMARD (N=642). Data from both trials was integrated for pts receiving placebo (PBO), UPA 15 mg once daily (QD) and UPA 30 mg QD. Stable background treatment of ≤2 non-bDMARDs was permitted, but not required. Analysis includes UPA monotherapy vs combination therapy for endpoints: ACR20/50/70 responses and change from baseline in pain and HAQ-DI (Wk 12); Static Investigator Global Assessment of Psoriasis of 0 or 1 and at least a 2-point improvement from baseline and PASI75/90/100 responses (Wk 16); proportion of pts achieving resolution of enthesitis, dactylitis, and minimal disease activity (Wk 24). Binary outcomes, using the Cochran-Mantel-Haenszel-method and continuous outcomes, using mixed-effects model, were analyzed for repeated measures in the subgroups of UPA monotherapy and combination therapy. Point estimates and 95% confidence intervals (CIs) of PBO subtracted treatment effect were calculated. Treatment-emergent adverse events (TEAEs) were analyzed.Results:Of 1916 pts, 574 (30%) received monotherapy and 1342 (70%) received combination therapy; 84% in combination therapy group received MTX +/- another non-bDMARD. Both UPA monotherapy and combination therapy led to improvements in efficacy vs PBO and across endpoints, for each dose, generally consistent point estimates of PBO subtracted treatment effect and associated overlapping CIs were observed (Figure 1). Generally, frequency of AEs and serious AEs, were comparable with UPA administered as monotherapy and combination therapy (Table 1). Frequency of AEs of serious infections and hepatic disorder were lower with monotherapy while frequency of AEs leading to discontinuation of study drug were lower with combination therapy. Most hepatic disorders were transient transaminase elevations.Conclusion:In the SELECT PsA trials, efficacy and safety of UPA was generally consistent when administered as monotherapy or when given in combination with non-bDMARDs. Results from this analysis support the use of UPA with or without concomitant non-bDMARDs.References:[1]Ianculescu I and Weisman MH, Clin Exp Rheumatol 2015; 33:S94–S97.[2]Mease PJ, et al.

Abstract
The aim of this work was to study the role of hepatic metabolism of compensatory growth in piglets induced by protein restriction and subsequent protein realimentation. Thirty-six weaned piglets were randomly distributed in a control group and a treatment group. The control group piglets were fed with a normal protein level diet (18.83% CP) for the entire experimental period (day 1-28). The treatment group piglets were fed with a protein-restriction diet (13.05% CP) for day 1 to day 14, and the diet was restored to normal protein level diet for day 15 to day 28. RNA-seq is used to analyze samples of liver metabolism on day 14 and day 28, respectively. Hepatic RNA-sequencing analysis revealed that some KEGG signaling pathways involved in glycolipid metabolism (eg, "AMPK signaling pathway," "insulin signaling pathway," and "glycolysis or gluconeogenesis") were significantly enriched on day 14 and day 28. On day 14, protein restriction promoted hepatic lipogenesis by increasing the genes expression level of ACACA, FASN, GAPM, and SREBP1C, decreasing protein phosphorylation levels of AMPKɑ and ACC in AMPK signaling pathway. In contrast, on day 28, protein realimentation promoted hepatic gluconeogenesis by increasing the concentration of G6Pase and PEPCK, decreasing protein phosphorylation levels of IRS1, Akt, and FoXO1 in insulin signaling pathway. In addition, protein realimentation activated the GH-IGF1 axis between the liver and skeletal muscle. Overall, these findings revealed the importance of liver metabolism in achieving compensatory growth.

Abstract
Objective: To understand the characteristics and explore the influencing factors of HBsAg positivity in methadone maintenance treatment (MMT) clinic patients. Methods: A face to face interview and medical record review were conducted in 1 040 patients at three MMT clinics in Guangxi from September to November in 2014. The questionnaire information included general demographic characteristics, drug use history, MMT status, sexual behaviors, and health status, etc. Blood samples were collected from the patients at the same time for the detections of the level of HBsAg, anti-HBs and anti-HCV. By using χ(2) test, unconditional logistic regression model and Bayesian network model the influencing factors for HBsAg positivity in MMT clinic patients and the complex network relationship among these factors were explored. Results: A total of 1 031 MMT clinic patients were surveyed, the HBsAg positive rate was 11.35% (117/1 031). The anti-HCV positive rate was 71.77% (740/1 031), among the anti-HCV positive patients, the HBsAg positive rate was 10.27% (76/740). After adjusting for the confounding factors, anti-HBs positive persons might not be HBsAg positive (OR=0.05, 95%CI: 0.03-0.09), and anti-HCV positive persons might not be HBsAg positive too (OR=0.30, 95%CI: 0.17-0.52) compared with anti-HBs negative and anti-HCV negative persons, respectively. The persons with family history of hepatitis B virus infection were more likely to be HBsAg positive compared those with no such family history (OR=5.30, 95%CI: 2.68-10.52). Bayesian network model analysis results showed that family history of hepatitis B virus infection and anti-HBs were directly related with HBsAg positivity. Anti-HCV, intravenous drug use in the past three months and other drug using during treatment were indirectly related with HBsAg positivity. Conclusions: Anti-HBs, family history of hepatitis B virus infection, anti-HCV, intravenous drug use in past three months and other drug use during treatment were related with the HBsAg positivity in MMT clinic patients. So, it is necessary to enhance health education, improve health awareness and decrease high risk behaviors to reduce the rate of HBV infection.

Abstract
AIMS To prevent the spread of brucellosis, a simple and rapid vertical flow technology (RVFT) for the detection of antibodies targeting brucellosis was developed. METHODS AND RESULTS In this study, Brucella sp. lipopolysaccharide was purified and used to detect brucellosis antibodies. Sheep IgG was used as a negative control. Colloidal gold-labeled recombinant staphylococcus aureus protein A was sprayed on a fibreglass membrane to prepare immunogold pads. Rapid vertical flow technology was used to detect Brucella in 1668 Sheep, 2743 bovine, 674 red deer and 420 human samples. The results indicated that the accuracy of this assay can reach 98%. CONCLUSIONS The established RVFT uses a single multifunctional buffer that can be used to detect antibodies in serum, plasma, whole blood and other biological samples while preserving the advantages of lateral-flow immunoassays. SIGNIFICANCE AND IMPACT OF THE STUDY This technology would be of great use in primary medical units and veterinary stations, and it is of great significance for the control of epidemic diseases.

Abstract
BACKGROUND Bisphenol A is widely used in the manufacture of polycarbonate plastics and has caused increasing concern over its potential adverse impacts on spermatogenesis. However, the effect of bisphenol A on spermiogenesis is yet to be explored. OBJECTIVES To evaluate whether bisphenol A has adverse effects on DNA integrity and protamination of spermatogenic cell. MATERIALS AND METHODS Newborn male mice were subcutaneously injected with bisphenol A (0.1, 5 mg/kg body weight, n = 15) or coin oil (control group, n = 20) daily from post-natal day 1 until 35. At post-natal day 70, epididymis caudal spermatozoa and testes were collected. Sperm count, sperm motility, and sperm morphology were analyzed. The sperm chromatin structure assay was performed to examine the sperm DNA fragmentation. Terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) method was used to assess apoptosis of spermatogenic cells. The ultrastructural features of testicular sections were examined under a transmission electron microscope. Western blot and RT-PCR were used to detect the expression levels of transition protein (Tnp) 1 and Tnp2, protamine (Prm) 1 and Prm2 protein, and mRNA in mice testes. RESULTS Bisphenol A significantly reduced sperm counts, impaired sperm motility, and increased the percentage of malformed spermatozoa. Poor sperm chromatin integrity and increased TUNEL-positive spermatogenic cells were also observed in mice exposed to bisphenol A. Ultrastructural analysis of testes showed that bisphenol A exposure caused incomplete chromatin condensation, retention of residual cytoplasm, and abnormal acrosome formation. In addition, the relative expression levels of Tnp2 and Prm2 in mice testes decreased significantly in bisphenol A groups. DISCUSSION AND CONCLUSION Our findings identified that neonatal bisphenol A exposure may negatively contribute to the sperm quality in adult mice. Mechanistically, we showed that bisphenol A reduced sperm chromatin integrity along with increased DNA damage, which may be due to poor protamination of spermatozoa.

Abstract
AIM Sarcopenia is a robust prognostic indicator of outcomes after surgery for colorectal cancer (CRC). However, there are no serum markers routinely available for estimating skeletal muscle mass (SMM). The present study aimed to describe a new sarcopenia index (SI), serum creatinine (Scr) × cystatin C-based glomerular filtration rate, and investigate its association with short-term complications after curative resection of CRC. METHOD Consecutive patients who underwent curative resection of CRC from December 2011 to January 2017 were retrospectively identified. Skeletal muscle cross-sectional area was analysed on L3 computed tomographic images. Receiver operating characteristic curve analysis showed that the cutoff points of SI for sarcopenia were below 56.1 in men and below 43.7 in women. Patients were classified into low and high SI groups in accordance with these cutoff values. The association between SI and body composition and the impact of preoperative SI on postoperative outcomes were analysed. RESULTS Among 417 patients, SI showed a stronger correlation with skeletal muscle area (SMA) (r = 0.537, P < 0.001) than with the Scr/cystatin C ratio (r = 0.469, P < 0.001) and Scr (r = 0.447, P < 0.001). The low SI group had a lower SMA, lower preoperative haemoglobin, a higher prevalence of sarcopenia and experienced more postoperative complications compared with the high SI group (all P < 0.001). Multivariate logistic regression analysis showed that the independent risk factors for overall complications were low preoperative haemoglobin, low SI, sarcopenia and American Society of Anesthesiologists grade ≥ 3. CONCLUSION This new SI is a simple and useful surrogate marker for estimating SMM, and is associated with outcomes after CRC surgery.

Abstract
Objective: To estimate the prevalence of HIV/HCV co-infection and explore the influence factors and their interaction on HIV/HCV co-infection of patient's access to methadone maintenance treatment (MMT). Methods: A face to face interviews were conducted among 750 patients at two MMT clinics in Guangxi Zhuang Autonomous Region. The questionnaires information included demographic characteristics, HIV and HCV infection status, history of drug abuse, urine test for morphine, high risk sex behaviors, needle sharing, dropped out etc. Methods of χ(2) test one-way, multivariate logistic regression and interactions were used to analyze the related factors of HIV/HCV co-infection. Results: The study subjects included 750 participants, 18.31% (127/691) of patients were co-infected with HIV and HCV. The HIV/HCV co-infection rate in patients who shared needles with others or dropped out of treatment was 35.84% (81/226) and 19.88% (64/322) respectively, which were higher than those who have never shared needles or dropped out (9.89%, 46/465 and 17.07%, 63/369). Logistic regression analysis results showed that after adjusted for confounding factors, patients who shared needles (OR=4.50, 95%CI: 2.72-7.43) and dropped out of treatment (OR=1.71, 95%CI: 1.04-2.80) were more likely to be infected with HIV/HCV. Interaction analysis showed that sharing needles and dropping out of treatment exist additive effect on co-infection of HIV and HCV (RERI=4.21, AP=0.44, SI=1.95). Conclusions: Needle sharing and dropping out of treatment are associated with HIV/HCV co-infection. Health education, psychological counseling and other measures should be taken to reduce needle sharing and dropping out of MMT.

Abstract
In the pathological process of acute kidney injury (AKI), innate immune receptors are essential in inflammatory response modulation; however, the precise molecular mechanisms are still unclear. Our study sought to demonstrate the inflammatory response mechanisms in renal tubular epithelial cells via Toll-like receptor-4 (TLR-4) and dendritic cell-specific intercellular adhesion molecule 3-grabbing non-integrin 1 (DC-SIGN) signalling. We found that DC-SIGN exhibited strong expression in renal tubular epithelial cells of human acute renal injury tissues. DC-SIGN protein expression was increased significantly when renal tubular epithelial cells were exposed to lipopolysaccharide (LPS) for a short period. Furthermore, DC-SIGN was involved in the activation of p65 by TLR-4, which excluded p38 and c-Jun N-terminal kinases (JNK). Interleukin (IL)-6 and tumour necrosis factor (TNF)-α expression was decreased after DC-SIGN knock-down, and LPS induced endogenous interactions and plasma membrane co-expression between TLR-4 and DC-SIGN. These results show that DC-SIGN and TLR-4 interactions regulate inflammatory responses in renal tubular epithelial cells and participate in AKI pathogenesis.

Abstract
Renal cell carcinoma (RCC) is one of the most aggressive urologic cancers, however, the mechanism on supporting RCC carcinogenesis is still not clear. By using gene expression profile analysis and functional clustering, PDZ domain-containing 1 (PDZK1) was revealed to be downregulated in human clear cell renal cell carcinoma (ccRCC) samples, which was also verified in several independent public ccRCC data sets. Using PDZK1 overexpression and knockdown models in ccRCC cell lines, we demonstrated that PDZK1 inhibited cell proliferation, cell cycle G1/S phase transition, cell migration and invasion, indicating a tumor-suppressor role in the development and progression of ccRCC. Our study further demonstrated that PDZK1 inhibited cell proliferation and migration of ccRCC via targeting SHP-1. PDZK1 was further identified to suppress cell proliferation by blocking SHP-1 phosphorylation at Tyr536 via inhibition of the association between SHP-1 and PLCβ3, and then retarding Akt phosphorylation and promoting STAT5 phosphorylation in ccRCC cells. Moreover, the inhibitive effects of PDZK1 on SHP-1 phosphorylation and the tumor growth were verified in vivo by xenograft tumor studies. Accordingly, PDZK1 expression was negatively correlated with SHP-1 activation and phosphorylation, advanced pathologic stage, tumor weight and size, and prognosis of ccRCC patients. These findings have provided first lines of evidences that PDZK1 expression is negatively correlated with SHP-1 activation and poor clinical outcomes in ccRCC. PDZK1 was identified as a novel tumor suppressor in ccRCC by negating SHP-1 activity.

Abstract
BACKGROUND Cytomegalovirus (CMV) infection is deemed to be a major cause of morbidity and mortality in patients after kidney transplantation. The purpose of this study was to analyze the incidence of CMV infection and risk factors for CMV infection in our center, to help in determination of its impact on the kidney function in this patient population, and to provide new ideas for the prevention and treatment of CMV infection. METHODS A total of 319 kidney transplant recipients from our center were studied between January 2000 and December 2015. The CMV viral load in each kidney transplant patients was monitored with the use of CMV quantitative nucleic acid testing (CMV-QNAT). Laboratory data and other medical records were also collected. RESULTS The incidence of CMV infection was 8.8% in our studied patients. The patients within 3 to 6 months and 5 to 10 years after transplantation had a higher risk of CMV infection. CMV infection was probably correlated with lower white blood cell counts but elevated hemoglobin, serum creatinine, blood urea nitrogen, potassium, and estimated glomerular filtration rate (eGFR). Anti-CMV immunoglobulin (Ig)G and history of allograft rejection were also associated with CMV infection. In multivariate regression analysis, white blood cells, eGFR, anti-CMV IgG, and history of allograft rejection were the independent risk factors associated with CMV infection in kidney transplantation patients. CONCLUSIONS CMV infection was an important complication after kidney transplantation, particularly in these patients with allograft impairment.
