Abstract
Schizophrenia is a neurodevelopmental disorder that affects up to 1% of the general population. Various genes show associations with schizophrenia and a very weak nominal association with the tight junction protein, claudin-5, has previously been identified. Claudin-5 is expressed in endothelial cells forming part of the blood-brain barrier (BBB). Furthermore, schizophrenia occurs in 30% of individuals with 22q11 deletion syndrome (22q11DS), a population who are haploinsufficient for the claudin-5 gene. Here, we show that a variant in the claudin-5 gene is weakly associated with schizophrenia in 22q11DS, leading to 75% less claudin-5 being expressed in endothelial cells. We also show that targeted adeno-associated virus-mediated suppression of claudin-5 in the mouse brain results in localized BBB disruption and behavioural changes. Using an inducible 'knockdown' mouse model, we further link claudin-5 suppression with psychosis through a distinct behavioural phenotype showing impairments in learning and memory, anxiety-like behaviour and sensorimotor gating. In addition, these animals develop seizures and die after 3-4 weeks of claudin-5 suppression, reinforcing the crucial role of claudin-5 in normal neurological function. Finally, we show that anti-psychotic medications dose-dependently increase claudin-5 expression in vitro and in vivo while aberrant, discontinuous expression of claudin-5 in the brains of schizophrenic patients post mortem was observed compared to age-matched controls. Together, these data suggest that BBB disruption may be a modifying factor in the development of schizophrenia and that drugs directly targeting the BBB may offer new therapeutic opportunities for treating this disorder.

Abstract
Renal safety is a major concern during long-term antiviral treatment for chronic hepatitis B (CHB). This study aimed to investigate the prevalence of chronic kidney disease (CKD) in patients with CHB that had been treated with antiviral therapy. This was a single-centre, cross-sectional study in a real-life cohort in which all patients received antiviral treatment. Serum creatinine-based equations from the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) were used to estimate the glomerular filtration rate (GFR). CKD was defined as an eGFR <60 mL/min/1.73 m² or a urinary albumin to creatinine ratio ≥ 3 mg/mmol (defined as albuminuria). Univariate and multivariate analyses were conducted to determine the risk factors of CKD. A total of 1985 patients were included in the analysis from February 2015 to December 2015. The mean age and median duration of antiviral treatment was 42.20 years and 17.05 months, respectively. The overall prevalence of CKD was 7.9% (157/1985), with 44 patients experiencing decreased renal function (eGFR less than 60 mL/min/1.73 m²) and 129 patients with albuminuria. Patients with cirrhosis had a higher prevalence of a decreased GFR (4.3% vs 1.6%, P<.001) and albuminuria (11.1% vs 5.2%, P<.001) than those without cirrhosis. In the multivariate analysis, hypertension (Odds Ratio [OR] 4.564, P<.001), diabetes mellitus (OR 2.688, P<.001) and cirrhosis (OR 1.918, P<.001) were independent factors associated with the presence of CKD. CKD was a clinically significant comorbidity in patients with CHB. Special attention should be paid to cirrhotic patients and patients with the metabolic syndrome.

Abstract
OBJECTIVE The effects of DNA methyltransferase (DNMT) inhibitor RG108 on the proliferation and apoptosis of endometrial cancer was investigated, and whether its mechanism was related to the inhibition of DNMT3B, thereby affecting the human mutL homolog 1 (hMLH1) methylation status and its expression, was further studied. MATERIALS AND METHODS Culture of human endometrial cancer Ishikawa cell lines: cells grew adhering to the wall in Roswell Park Memorial Institute-1640 (RPMI-1640) medium (supplemented with 10% fetal bovine serum (FBS) and 2 mM L-glutamic acid). After the cells were treated with RG108, the changes in cell viability were detected via methyl thiazolyl tetrazolium (MTT) assay. The effect of RG108 on cell cycle was detected via flow cytometry, and its effect on cell apoptosis was detected via flow cytometry and TUNEL. Moreover, the methylation status of hMLH1gene in endometrial cancer cells was detected via methylation specific-PCR (MSP), and the changes in DNMT3Band hMLH1 expressions were detected via RT-PCR and Western blotting, respectively. RESULTS MTT results showed that RG108 inhibited the cell viability in a dose-dependent and time-dependent manner. Flow cytometry revealed that RG108 blocked the cell cycle in G2/M phase and promoted the apoptosis, and TUNEL assay further proved that RG108 promoted the apoptosis. It was found in the detection via MSP that the methylated hMLH1 gene was significantly reduced after 72 h of treatment with RG108. Besides, RT-PCR and Western blotting showed that RG108 inhibited the DNMT3B expression and activated the hMLH1 expression. CONCLUSIONS The demethylation drug RG108 can significantly inhibit the proliferation of endometrial cancer cells, block the cell cycle in the G2/M phase and induce the cell apoptosis, which is a new candidate drug in the treatment of endometrial cancer. RG108 realizes the hMLH1 demethylation and increases the hMLH1 expression through inhibiting the expression of DNMT3B.

Abstract
Objective: To explore clinical and laboratory factors that influencing treating procedure of cytomegalovirus retinitis (CMVR) after allogeneic bone marrow hematopoietic stem cell transplantation (HSCT). Methods: This is a retrospective case series study. A total of 9 CMVR patients (15 eyes) between January 2016 and March 2017 were included in this study. All patients received intravenous or oral ganciclovir, together with intravitreous injection of ganciclovir alone or combined with foscanet sodium. One day before the first injection, aqueous humor samples from the affected eyes were collected, and CMV-DNA and interleukin-8 (IL-8) level were examined. Blood samples were acquired and CMV-DNA was examined too. Best corrected visual acuity, intraocular pressure (Goldmann), slit-lamp and fundus examination, ultra-wide fundus photography were performed before the first injection and every visit since then. Fifty eyes were divided into stop treating group (Group A) and continue-to-treat group (Group B) according to whether local treatment could be seized after loading phase. Image-Pro plus 6.0 was exploited to determine the area of CMVR in the retina, together with number of quadrants involved and whether macular was involved.Then the clinical and laboratory data were compared between two groups. ROC curve was used to calculate the cutoff values for quantitative factors that showed significant differences between two groups. Results: The interval time between HSCT and diagnosis of CMVR, visual acuity and CMV-DNA in the blood at baseline, area of CMVR and number of quadrants involved and whether macular was involved didn't show any difference between two groups. But the intraocular pressure (Z=-2.488, P=0.017), CMV-DNA (Z=-2.239, P=0.013) and IL-8 level (Z=-2.475, P=0.012) in aqueous humor at baseline, proportion of eyes with active inflammation in anterior (P=0.003) and proportion of eyes with ocular hypertension (P=0.021) in group B were significantly higher than those in group A. The cutoff values of intraocular pressure, CMV-DNA and IL-8 level in aqueous humor at baseline were 14.5 mmHg (P=0.013), 2.99×10(5) copy/ml (P=0.025) and 447.8 pg/ml (P=0.013), respectively. Conclusion: Higher intraocular pressure, CMV-DNA and IL-8 in aqueous humor at baseline, especially combined with active inflammation in anterior segment and ocular hypertension suggest longer treating period and more times of intravitreous injections.

Abstract
Cystic echinococcosis (CE) caused by the cestode Echinococcus granulosus (E. granulosus) is a zoonotic parasitic disease. The effective immune evasion mechanisms of E. granulosus allow it to parasitize its hosts. However, the status of the innate and adaptive immune cells and their contributions to E. granulosus progression remain poorly understood. In this study, we aimed to determine the impact of E. granulosus infection on T cells, NK cell responses and TGF-β expression during the early infection phase in BALB/c mice. In E. granulosus infections, there was an increasing tendency in the percentage of CD4+ CD25+ T cells and CD4+ Foxp3+ T cells and peripheral blood TGF-β levels and relative expression of the Foxp3 gene. Moreover, there were a decreasing tendency in the percentage of NK cells and NK cell cytotoxicity and the expression of NKG2D on NK cells. The TGF-β1/Smad pathway was activated by E. granulosus in mice. Above results can be reversed by the inhibitor SB-525334 (potent activin receptor-like kinase 5 inhibitor). These results suggest that the TGF-β/Smad pathway plays an important role in changes of T-cell or NK cell responses. These results may contribute to revealing the preliminary molecular mechanisms in establishing hydatid infection.

Abstract
Objective: To evaluate the efficacy and safety of tiotropium Respimat in the treatment of chronic obstructive pulmonary disease (COPD) according to the Cochrane systematic evaluation. Methods: The Cochrane Library, PubMed, EMbase, CNKI, VIP and CBM, Wanfang Data were searched(from the foundation date to Jan. 2016) for the randomized controlled trials (RCTs) of tiotropium Respimat in the treatment of patients with COPD. Two reviewers independently retrieved the RCTs according to the inclusion and exclusion criteria, assessed the methodological quality of the included trials.and performed statistical analysis on the data using RevMan 5.3 software. Results: Totally 11 RCTs on efficacy were finally included.The results of the combined analysis showed that FEV(1) was significantly improved in the tiotropium Respimat group than that in the placebo group[MD=0.12, 95%CI(0.10-0.14), P<0.000 01], while FEV(1) was similar between the tiotropium Respimat group and the tiotropium HandiHaler group[5 μg: MD=0.00, 95%CI(-0.04-0.04), P=0.94; 2.5 μg: MD=-0.04, 95%CI(-0.10-0.01), P=0.12; 10 μg: MD=0.02, 95%CI(-0.06-0.09), P=0.66]. FVC was significantly improved in the tiotropium Respimat group than that in the placebo group[MD=0.18, 95%CI(0.09-0.28), P=0.0002], while FVC was similar between the tiotropium Respimat group and the HandiHaler group[2.5 μg: MD=-0.06, 95%CI(-0.16-0.04), P=0.24; 5 μg: MD=-0.00, 95%CI(-0.08-0.08), P=1.00; 10 μg: MD=0.02, 95%CI(-0.14-0.19), P=0.78]. The risk of acute exacerbations was lower in the tiotropium Respimat group (5 μg / kg) than in the placebo group [OR=0.72, 95%CI(0.60-0.86), P=0.000 3]. It was similar in the tiotropium Respimat group (5 μg) and the HandiHaler group[OR=1.01, 95%CI(0.94-1.09), P=0.71]. The SGRQ total score of the tiotropium Respimat group (5 μg) was significantly different from that of the placebo group[MD=-3.6, 95%CI(-3.88--3.32), P<0.000 01]. C(max, ss) and AUC(0-6 h, ss) were also similar between the tiotropium Respimat group and the HandiHaler group[MD=0.2, 95%CI(-5.1-5.5), P=0.94]; MD=-1.01, 95%CI(-11.78-9.77), P=0.85]. Nine RCTs were included in the evaluation of the incident rates of adverse drug reactions(ADR). There was no significant difference between the tiotropium Respimat group HandiHaler group and the placebo group[RR=0.95, 95%CI(0.89-1.00), P=0.05], [OR=1.07, 95%CI(1.00-1.16), P=0.06]. Conclusions: The efficacy and safety of tiotropium Respimat was similar to tiotropium HandiHaler in the treatment of COPD. They can effectively improve the pulmonary function and clinical symptoms of patients. But the long-term efficacy and safety of tiotropium Respimat still need to be confirmed by higher quality and larger RCTs with long-term follow-up.

Abstract
BACKGROUND AND OBJECTIVE Calprotectin (S100A8/A9) is a heterodimer of S100A8 and S100A9 and is associated with multiple inflammatory diseases, including Crohn's disease, rheumatoid arthritis and periodontitis. Levels of calprotectin are elevated in the gingival crevicular fluid of patients with periodontitis; however, the effects of calprotectin on human gingival fibroblasts (HGFs) remain unknown. This study investigated the proinflammatory activity of calprotectin on HGFs and the functional receptors and signaling pathways engaged by calprotectin. MATERIAL AND METHODS HGFs were stimulated by equimolar concentrations of S100A8 and/or S100A9, and the expression levels of interleukin (IL)-6 and IL-8 were detected using real-time quantitative polymerase chain reaction and enzyme-linked immunosorbent assays. The calprotectin receptors were identified by pre-incubating HGFs with the toll-like receptor (TLR) 4 inhibitor or the antibody targeting the advanced glycation end product receptor (RAGE). The involvement of reactive oxygen species (ROS) and signaling pathways were also investigated by treating HGFs with ROS inhibitor or specific pathway inhibitors, respectively. RESULTS S100A9 and S100A8/A9 significantly upregulated IL-6 and IL-8 expression, which was inhibited upon treatment with the TLR4 inhibitor TAK242. Pretreatment with RAGE-blocking antibodies did not affect cytokine expression. Additionally, S100A9 promoted the production of IL-6 and IL-8 from HGFs via different signaling pathways. IL-6 expression was upregulated via the NF-κB, c-Jun amino-terminal kinase (JNK) 1/2 and p38 mitogen-activated protein kinase (MAPK) pathways, and IL-8 expression was upregulated via NF-κB, p38, JNK1/2 and extracellular-regulated kinase 1/2 MAPK pathways. The release of both cytokines was dependent upon the production of ROS. CONCLUSION Our findings suggest that calprotectin exerts proinflammatory effects on HGFs via the S100A9 subunit and TLR4-mediated NF-κB and MAPK signaling pathways.

Abstract
Our previous studies showed that macrophages (MФs), especially myeloma-associated MФs (MAMs), induce chemoresistance in human myeloma. Here we explored the potential of targeting MФs, by using colony-stimulating factor 1 receptor (CSF1R)-blocking mAbs, to treat myeloma. Our results showed that CSF1R blockade specifically inhibited the differentiation, proliferation and survival of murine M2 MФs and MAMs, and repolarized MAMs towards M1-like MФs in vitro. CSF1R blockade alone inhibited myeloma growth in vivo, by partially depleting MAMs, polarizing MAMs to the M1 phenotype, and inducing a tumor-specific cytotoxic CD4+ T-cell response. Similarly, genetically depleting MФs in myeloma-bearing MMDTR mice retarded myeloma growth in vivo. Furthermore, the combination of CSF1R blockade and chemotherapy such as bortezomib or melphalan displayed an additive therapeutic efficacy against established myeloma. Finally, a fully human CSF1R blocking mAb, similar to its murine counterpart, was able to inhibit the differentiation, proliferation and survival of human MФs. Thus, this study provides the first direct in vivo evidence that MΦs and MAMs are indeed important for myeloma development and progression. Our results also suggest that targeting MAMs by CSF1R blocking mAbs may be promising methods to (re)sensitize myeloma cells to chemotherapy and promote anti-myeloma immune responses in patients.

Abstract
Studies examining the relation of body mass index (BMI) and mortality in patients with lung cancer have shown diverse results. We conducted a meta-analysis to investigate the association using all available studies from January 1982 to October 2016. PubMed and EMBASE were searched to identify relevant studies. We calculated the summary hazard ratio (HR) and 95% confidence interval (CI) using random effects model. The dose-response relationship was assessed by random effects meta-regression model. Fifty-five articles from 51 studies involving 3 152 552 subjects (males, 54.8%) were included. The pooled results suggested that on average a high BMI decreased risk of death from lung cancer or all-cause. Each 5 kg/m2 increase in BMI had a 12% lower risk of lung cancer-specific mortality (HR=0.88, 95% CI: 0.75-1.02, P=0.09) and a 14% lower risk of all-cause mortality (HR=0.86, 95% CI: 0.77-0.96, P<0.01). When stratifying by ethnicity, each 5 kg/m2 increase in BMI was associated with 22% and 28% reduction, respectively, in the risk of lung cancer-specific mortality (P<0.01) and all-cause mortality (P<0.01) in Asians, but no association was found in Westerners (P=0.51 and P=0.53, respectively). In conclusion, lung cancer patients with a higher BMI have a longer survival than those with a lower BMI. Considering the significant heterogeneity between included studies, future studies are needed to confirm these findings.

Abstract
BACKGROUND AND OBJECTIVE Vitamin D-binding protein (DBP) is a highly expressed plasma protein with many important functions, including transport of vitamin D metabolites, sequestration of actin, control of bone metabolism and modulation of immune and inflammatory responses. Previous results of our study indicated an association between DBP and periodontitis. We hypothesized that periodontium might be another source of DBP in gingival crevicular fluid other than serum. MATERIAL AND METHODS DBP expression was examined in dental and periodontal tissues of monkeys by immunohistochemistry, and in primary cells isolated from human dental and periodontal tissues by reverse transcription plus the polymerase chain reaction and immunocytochemistry. RESULTS DBP was constitutively expressed and widely distributed in dental and periodontal tissues of primates. Their immunoreaction was evident in gingival epithelium, particularly in junctional epithelium, and in mineralizing areas of the dental pulp, periodontal ligament and bone marrow. Correspondingly, mRNA and protein expression were detected in primary human gingival epithelial cells, dental pulp cells and periodontal ligament cells. CONCLUSION DBP is highly expressed and widely distributed in dental and periodontal tissues, which may take an active part in local host defense and hard tissue metabolism.

Abstract
OBJECTIVE To evaluate the methods of flow cytometric-dihydrorhodamine 123 (DHR) analysis, gp91 protein detection, gene mutation analysis for the precise diagnosis of chronic granulomatous disease (CGD). METHOD Clinical and laboratory data of patients with CGD confirmed by gene mutation analysis from 2008 to 2015 in Children's Hospital of Fudan University were retrospectively reviewed.The results of respiratory burst, gp91 protein level, and gene mutations were analyzed.The relationships among these three methods were explored. RESULT A total of 138 patients of CGD with confirmed gene mutation were included in this study, of them, 123 cases(89.1%) had CYBB gene mutation, 4 cases(2.9%) had CYBA mutation, 5 cases(3.6%) had NCF1 mutation and 6 cases(4.4%) had NCF2 mutation.The range of stimulatory index (SI) was 0.8-60.5, the 25 th, 50 th, 75th percent was 1.7, 2.7, 4.7; 112 cases had the results of gp91, of them, 100 with gp91(0,) 2 with gp91(-), and 10 with gp91(+) . Six mutations, which were not reported before, were c. 76-77delTT, c. 343-344delCA, c. 481A>T, c. 1152G>C, c. 1613G>A for CYBB gene, and c. 137T>G for NCF2 gene. Among CGD patients with CYBB mutation, SI of patients with gp91(+) was higher than patients with gp91(0) 14.6 vs. 2.5(t=44.21, P=0.004). Patients of NCF1 mutation had higher SI than patients with CYBB mutation, 17.7 vs. 2.5 (t=60.8, P=0.003). CONCLUSION Flow cytometric-DHR analysis and gp91 protein detection are important diagnostic methods for CGD, they could help the precise diagnosis of CGD.Different mutation types, different mutation genes could have impact on the results of respiratory burst and gp91 level.The application of diagnostic technology from function, protein to gene analysis could help precise diagnosis of CGD.

Abstract
Objective The treatment of refractory lupus nephritis (LN) remains challenging for clinicians because these patients either do not respond to conventional therapy or relapse during the maintenance treatment period. The aim of this study was to investigate the efficacy and safety of bortezomib combined with glucocorticoids in refractory lupus patients. Methodology Five refractory LN patients aged 21 to 43 years (four females and one male) with biopsy-proven diagnosis (four with type IV and one with type V+IV) were recruited. These patients received bortezomib therapy for four cycles (1.3 mg per square meter of body surface area as an intravenous bolus on days 1, 4, 8, and 11 of 21-day cycles) and glucocorticoids (methylprednisolone 0.5 g/d intravenously for three days, followed by prednisone 0.6 mg/kg/d orally for four weeks, with gradual tapering to 10 mg/d). Proteinuria, serum albumin and creatinine, and immunological parameters were assessed, and adverse effects were also evaluated. Results After two to four bortezomib treatment cycles, four patients achieved partial remission with decreases in SLE disease activity index scores from the range of 12-16 to that of 4-8. The patients also exhibited a decline in proteinuria and an elevation of albumin level after treatment. SCr level was decreased in three of five patients with elevated SCr at baseline. The anti-autoantibodies and complements were also improved. Adverse events were of grades 1-2 and included transient thrombocytopenia, gastrointestinal symptoms and acroesthesia. During a 6- to 24-month follow-up period, three patients achieved complete remission, and one had partial remission. However, one patient received renal replacement therapy. Conclusion Bortezomib combined with glucocorticoids reduces proteinuria, improves renal function and decreases anti-autoantibodies, with good tolerance and mild adverse events, thus representing an alternative therapy for refractory LN and warranting further study.

Abstract
OBJECTIVE Advanced parental age has raised additional concern as a risk factor of autism. We conducted a meta-analysis of observational studies investigating the association between advanced parental age and risk of autism. METHOD PubMed, EMBASE, and Web of Science were searched for reports published up to November 11, 2015. Risk estimates from individual studies were pooled using random-effects models. RESULTS Twenty-seven studies were included in the meta-analysis. Compared with the reference points, the lowest parental age category was associated with a reduced risk of autism in the offspring, with adjusted odds ratios (ORs) 0.89 (95% confidence intervals [CIs] 0.75-1.06) and 0.81 (95% CI 0.73-0.89) for mother and father, respectively, and the highest parental age category was associated with an increased risk of autism in the offspring, with adjusted ORs 1.41 (95% CI 1.29-1.55) and 1.55 (95% CI 1.39-1.73) for mother and father respectively. Dose-response meta-analysis indicated that an increase of 10 years in maternal and paternal age was associated with an 18% and 21% higher risk of autism. CONCLUSION Advanced parental age was associated with an increased risk of autism in the offspring. More mechanistic studies are needed to further explain this positive association.

Abstract
AIMS The lower limit of exposure to cyclosporine A (CsA) has not yet been established in donation after cardiac death (DCD) renal transplantation recipients with delayed graft function (DGF) receiving enteric-coated mycophenolate sodium (EC-MPS) therapy. Stable and adequate mycophenolic acid (MPA) dosing may facilitate lower CsA exposure after DCD renal transplantation in recipients with DGF without compromising safety. METHODS A 12-month, single-centre open-label prospective trial was performed in our centre. According to their DGF risk index using the previous DGF prediction models, we divided up the patients on oral CsA into either a DGF group (n = 26) and no DGF group (n = 48). All of the patients initially received the standard EC-MPS dosing (1440 mg/day). The initial dose of CsA in the low risk of DGF group was 4.5 mg/kg/day and in the high risk of DGF group was 2.5 mg/kg/day. Efficacy parameters, safety and tolerability were assessed over a 12-month study period. RESULTS The incidence of DGF was 18.5% in the 162 DCD recipients. Between the DGF group and the no DGF group, the 1-year patient survival and graft survival were not significantly different. The incidence of BPAR was higher in the DGF group (26.9% vs. 8.3%, p = 0.032). Most patients in the DGF group had recovery of renal function after 1 month. The adverse events between the two groups were not significantly different. The daily EC-MPS doses of the DGF group were significantly higher than the no DGF group before the 6-month follow-up period. There were no significant differences between the two groups regarding the mean AUC levels during the follow-up period. CONCLUSIONS These results show that low expose CsA with standard dosing of EC-MPS and thymoglobulin was efficacious, safe and well-tolerated in DCD renal transplant recipients with DGF in China. Furthermore, stable and adequate MPA exposure helped to reduce the dose of and exposure to CsA. Thus, this may lead to less-induced nephrotoxicity and better renal function recovery.
