Abstract
BACKGROUND The prevalence of depressive disorder is increasing due to a variety of factors, which brings a huge strain on individuals, families and society. This study aims to investigate whether there is Frontal Theta Asymmetry (FTA) in depressed patients, and whether FTAs are related to depression severity and cognitive function changes in depressed patients. METHODS Participants who met the inclusion criteria were enrolled in this study. Socio-demographic data of each participant were recorded. Zung's self-rating Depression Scale was used to assess the depression status of participants. P300 was used to evaluate the cognitive function of participants. EEG data from participants were collected by the NeuroScan SynAmps RT EEG system. t-test, Wilcoxon rank-sum test and Chi-square test were used to detect the differences of different variables between the two groups. Multiple linear regression analysis and multiple logistic regression analysis were used to analyze relationships between FTAs in different regions and participants' depression status and cognitive function. RESULTS A total of 66 depressed participants and 47 healthy control participants were included in this study. The theta spectral power of the left frontal lobe was slightly stronger than that of the right frontal lobe in the depression group, while the opposite was true in the healthy control group. The FTA in F3/F4 had certain effects on the emergence of depression in participants, the emergence of depression in participants and Changes in cognitive function. CONCLUSIONS FTAs are helpful to assess the severity of depression and early identify cognitive impairment in patients with depression.

Abstract
Objectives This study aimed to explore the influence of depression severity, disease course, treatment status, and other factors on cognitive function in adolescents with depressive disorders. Methods Participants who met the inclusion criteria were enrolled in the study. Sociodemographic data of each participant were recorded, including age, sex, and family history of mental disorders. Zung's Self-Rating Depression Scale was used to assess depression status in adolescents. Moreover, P300 and mismatch negativity (MMN) were used to objectively evaluate the participants' cognitive function. Results Only 26.8% of the adolescents with depression received standard antidepressant treatment. The latencies of N2 (267.80±23.34 ms), P3 (357.71±32.09 ms), and MMN (212.10±15.61 ms) in the adolescent depression group were longer than those in the healthy control group (p<0.01). Further analysis revealed that the latency of MMN was extended with increased levels of depression in adolescents. The MMN latency was short in participants with depression receiving standardized treatment. Furthermore, the latency of MMN was positively correlated with the severity and duration of depression (correlation coefficients were 0.465 and 0.479, respectively) (p<0.01). Conclusion Receiving standardized treatment and shortening the course of depression can reduce cognitive impairment in adolescents with depression.

Abstract
P-glycoprotein (Pgp) overexpressed in blood brain barrier (BBB) is hypothesized to lower brain drug concentrations and thus inhibit anticonvulsant effects in drug-resistant epilepsy. Pluronic P85 (P85) was proved to enhance the delivery of drugs into the brain by inhibition of Pgp. To determine whether the surfactant P85 [versus Pgp inhibitor tariquidar (TQD)] enhance phenytoin (PHT) into the brain in drug-resistant rats with chronic mesial temporal lobe epilepsy (MTLE) induced by lithium-pilocarpine, in brain of which Pgp were overexpressed, then direct verification of PHT transport via measurement of PHT concentration in brain using microdialysis. The drug-resistant model rats were randomly divided into three groups, which were treated with PHT, 1%P85 + PHT, or PHT+TQD, respectively. 1%P85 + PHT treatment displayed a lower ratio of the area under the curve (AUC) of the PHT concentration in the brain/plasma even than that of the PHT treatment in model rats (p < 0.05), while PHT+TQD showed the highest ratio of the AUC of all treatments. However, the ratio of the PHT concentration in the liver/plasma was similar in three model groups (p > 0.05). For the ratio of the kidney/plasma, PHT+TQD treatment model group had the highest ratio of the other treatments in model rats. Thus, P85 oppositely decreased PHT concentration in brain in drug-resistant model rats with Pgp overexpressed MTLE while TQD could increase PHT distribution in brain.

Abstract
OBJECTIVE The goal was to characterize short-term kidney status and describe variation in early care utilization in a multicenter cohort of patients with childhood-onset systemic lupus erythematosus (cSLE) and nephritis. METHODS We analyzed previously collected prospective data from North American patients with cSLE with kidney biopsy-proven nephritis enrolled in the Childhood Arthritis and Rheumatology Research Alliance (CARRA) Registry from March 2017 through December 2019. We determined the proportion of patients with abnormal kidney status at the most recent registry visit and applied generalized linear mixed models to identify associated factors. We also calculated frequency of medication use, both during induction and ever recorded. RESULTS We identified 222 patients with kidney biopsy-proven nephritis, with 64% class III/IV nephritis on initial biopsy. At the most recent registry visit at median (interquartile range) of 17 (8-29) months from initial kidney biopsy, 58 of 106 patients (55%) with available data had abnormal kidney status. This finding was associated with male sex (odds ratio [OR] 3.88, 95% confidence interval [95% CI] 1.21-12.46) and age at cSLE diagnosis (OR 1.23, 95% CI 1.01-1.49). Patients with class IV nephritis were more likely than class III to receive cyclophosphamide and rituximab during induction. There was substantial variation in mycophenolate, cyclophosphamide, and rituximab ever use patterns across rheumatology centers. CONCLUSION In this cohort with predominately class III/IV nephritis, male sex and older age at cSLE diagnosis were associated with abnormal short-term kidney status. We also observed substantial variation in contemporary medication use for pediatric lupus nephritis between pediatric rheumatology centers. Additional studies are needed to better understand the impact of this variation on long-term kidney outcomes.

Abstract
RATIONALE Emphysematous hepatitis (EH) is a rare and fulminant gas-forming liver infection. Only 3 patients were successfully treated. Diabetes mellitus and a history of digestive system cancer may predispose individuals to EH. Computed tomography (CT) findings support the diagnosis of EH and monitor progress. PATIENT CONCERNS A 48-year-old man with diabetes presented with nausea, vomiting (gastric contents) and diarrhea. Laboratory test results revealed elevated levels of inflammatory indicators and abnormal liver function. CT showed a large-scale air collection with some remaining parenchymal debris in the left lobe of the liver. Remarkably, no fluid was observed inside the lesion. DIAGNOSE The abdominal CT features and laboratory examination results rationalized the diagnosis of EH. INTERVENTIONS AND OUTCOMES The patient finally recovered from this severe disease through a series of effective treatments, including strict glucose control, sensitive antibiotic therapy, and subsequent percutaneous drainage. LESSONS EH generally deteriorates rapidly and eventually leads to death. This case will raise awareness of the rare and severe disease, strengthen diagnostic capacities, and provide advice to treat it.

Abstract
BACKGROUND Children with juvenile idiopathic arthritis (JIA) who achieve a drug free remission often experience a flare of their disease requiring either intraarticular steroids (IAS) or systemic treatment with disease modifying anti-rheumatic drugs (DMARDs). IAS offer an opportunity to recapture disease control and avoid exposure to side effects from systemic immunosuppression. We examined a cohort of patients treated with IAS after drug free remission and report the probability of restarting systemic treatment within 12 months. METHODS We analyzed a cohort of patients from the Childhood Arthritis and Rheumatology Research Alliance (CARRA) Registry who received IAS for a flare after a period of drug free remission. Historical factors and clinical characteristics and of the patients including data obtained at the time of treatment were analyzed. RESULTS We identified 46 patients who met the inclusion criteria. Of those with follow up data available 49% had restarted systemic treatment 6 months after IAS injection and 70% had restarted systemic treatment at 12 months. The proportion of patients with prior use of a biologic DMARD was the only factor that differed between patients who restarted systemic treatment those who did not, both at 6 months (79% vs 35%, p < 0.01) and 12 months (81% vs 33%, p < 0.05). CONCLUSION While IAS are an option for all patients who flare after drug free remission, it may not prevent the need to restart systemic treatment. Prior use of a biologic DMARD may predict lack of success for IAS. Those who previously received methotrexate only, on the other hand, are excellent candidates for IAS.

Abstract
BACKGROUND Social determinants of health (SDH) greatly influence outcomes during the first year of treatment in rheumatoid arthritis, a disease similar to polyarticular juvenile idiopathic arthritis (pJIA). We investigated the correlation of community poverty level and other SDH with the persistence of moderate to severe disease activity and functional disability over the first year of treatment in pJIA patients enrolled in the Childhood Arthritis and Rheumatology Research Alliance Registry. METHODS In this cohort study, unadjusted and adjusted generalized linear mixed effects models analyzed the effect of community poverty and other SDH on disease activity, using the clinical Juvenile Arthritis Disease Activity Score-10, and disability, using the Child Health Assessment Questionnaire, measured at baseline, 6, and 12 months. RESULTS One thousand six hundred eighty-four patients were identified. High community poverty (≥20% living below the federal poverty level) was associated with increased odds of functional disability (OR 1.82, 95% CI 1.28-2.60) but was not statistically significant after adjustment (aOR 1.23, 95% CI 0.81-1.86) and was not associated with increased disease activity. Non-white race/ethnicity was associated with higher disease activity (aOR 2.48, 95% CI: 1.41-4.36). Lower self-reported household income was associated with higher disease activity and persistent functional disability. Public insurance (aOR 1.56, 95% CI 1.06-2.29) and low family education (aOR 1.89, 95% CI 1.14-3.12) was associated with persistent functional disability. CONCLUSION High community poverty level was associated with persistent functional disability in unadjusted analysis but not with persistent moderate to high disease activity. Race/ethnicity and other SDH were associated with persistent disease activity and functional disability.

Abstract
A chondroma is a common benign cartilaginous tumor. However, a primary soft tissue chondroma of the posterior mediastinum is very rare. We herein report a case involving a 51-year-old man with a posterior mediastinal mass. The mass was dissected by thoracoscopy through the eighth intercostal space. Pathological examination led to a definitive diagnosis of a primary mediastinal chondroma with no criteria of malignancy. Preoperative diagnosis of a posterior mediastinal soft tissue chondroma is not easy because of its rarity and lack of typical features other than calcification. When a posterior mediastinal well-circumscribed soft tissue mass contains calcification and shows no obvious enhancement, the possibility of a soft tissue chondroma should be considered.

Abstract
BACKGROUND/OBJECTIVE In recent years, herbal extracts are becoming increasingly popular ingredients added in cosmetics; however, the assessment of their potential adverse effects on the skin remains unclear. As Coptis, Phellodendron amurense, curcumin, and shikonin are herbs currently used in cosmetic ingredients, the aim of this study was to assess their skin photoallergy (PA) potential and the concentrations at which they could safely be used. METHODS In the patch test, Coptis, P. amurense, curcumin, and shikonin with 5, 10, 25, and 50% concentration were applied on 33 healthy Chinese subjects using the T.R.U.E. TEST® patch test system for 48 h. Photopatch testing was performed on 206 Chinese subjects with predisposed photosensitivity history using the Scandinavian photopatch series, and subjects were irradiated by 50% UVA minimum erythema dose. Photopatch testing of herbal extracts was then performed on subjects diagnosed with PA. RESULTS Thirty-three subjects (14 with type III skin and 19 with type IV skin) completed contact patch testing of herbal extracts. Coptis induced a contact allergy (CA) reaction on 2 subjects at 25% concentration and on 2 subjects at 10% concentration. P. amurense induced a CA reaction on 1 subject at 10% concentration and on 1 subject at 5% concentration. Shikonin induced a stimulating reaction on 1 subject at 10% concentration. Curcumin induced a stimulating reaction on 1 subject at 10% concentration. Of the 206 Chinese subjects predisposed for photosensitivity, 10.19% had PA, 16.5% showed CA, and 1.45% had both PA + CA. PA-induced substances were promethazine hydrochloride (15%, n = 31), chlorpromazine hydrochloride (10.84%, n = 19), perfume mix (5.82%, n = 12), atranorin (3.39%, n = 7), 6-methyl coumarine (3.39%, n = 7), balsam Peru (1.94%, n = 4), fentichlor (1.94%, n = 4), 3,3',4',5-tetrachloro salicylanilide (0.97%, n = 2), hexachlorophene (0.97%, n = 2), chlorhexidine digluconate (0.97%, n = 2), and 4-aminobenzoic acid 2-hydroxy-4-methoxybenzophenone (0.97%, n = 2). Coptis at 25, 10, and 5% concentration and P. amurense, shikonin, and curcumin each at 10 and 5% concentration induced negative photopatch test results in all 10 photosensitive subjects. CONCLUSION We have shown that Coptis, shikonin, or curcumin at 5% concentration in cosmetics could be applied safely without inducing contact allergic and photosensitive reactions on the skin. These findings advance the understanding of herbal extract use in cosmetic ingredients as related to the fields of dermatopharmacology and dermatotoxicology.

Abstract
BACKGROUND We aimed to investigate the utility of albumin-to-glutamyltransferase ratio (AGR) as a new biomarker to distinguish hepatic carcinoma from hepatitis, as early disease diagnosis, prognosis or monitoring could improve patient management and outcomes. METHODS Clinical characteristics of 34 hepatitis (women 19), 88 cirrhosis (women 22) and 52 hepatic carcinoma (women 9) cases were retrospectively reviewed. Patients diagnosed with cirrhosis were classified by Child-Pugh score and the presence of ascites. The differences among groups were evaluated by the Kruskal-Wallis test and Mann-Whitney U. The linear correlation between variables was assessed by Spearman's correlation analysis. The diagnostic value of albumin-to-glutamyltransferase (AGR) was considered using receiver operating characteristic (ROC) curves. Multiple logistic regression analysis and univariate logistic regression analysis were used to identify AGR as an independent predictor in liver disease progression. RESULTS The significant differences among the hepatitis vs. cirrhosis vs. and hepatic carcinoma were AST (108.50 ± 184.00 vs. 38.00 ± 21.50 vs. 47.00 ± 71.00, p < 0.01), TP/AST (TAR, 0.67 ± 0.69 vs. 1.77 ± 0.87 vs. 1.36 ± 0.95, p < 0.01), and ALB/GGT (AGR, 0.32 ± 0.27 vs. 0.67 ± 0.43 vs. 0.20 ± 0.26, p < 0.05). At the same time, AST (32.00 ± 13.50 vs. 53.00 ± 23.00 vs. 114.50 ± 42.50, p < 0.05) and TAR (2.15 ± 0.72 vs. 1.28 ± 0.74 vs. 0.64 ± 0.39, p < 0.05) were higher but AGR (0.86 ± 0.54 vs. 0.46 ± 0.32 vs. 0.26 ± 0.22, p < 0.05) was lower in Child-Pugh class C group compared with group B and C. TAR (1.92 ± 0.73 vs. 0.98 ± 0.89, p < 0.01) and AGR (0.79 ± 0.52 vs. 0.46 ± 0.28, p < 0.05) were significantly elevated in the serum of cirrhosis with no ascites compared with the cirrhosis patients suffered from ascites, while AST (35.00 ± 14.50 vs. 63.00 ± 44.50, p < 0.01) was reduced in cirrhosis patients with no ascites. Furthermore, AST (r = 0.4490, p<0.01) was positively correlated with AFP, TAR (r = -0.4393, p < 0.01) and AGR (r = -0.4395, p < 0.01) were negatively correlated with AFP. The ROC curve analysis for AST had an area under the curve (AUC) ranging from 0.66 to 0.82, TAR ranged from 0.64 to 0.80 and AGR ranged from 0.54 to 0.72. Multiple logistic regression analysis revealed AGR as an independent parameter to distinguish liver can¬cer to hepatitis, and AGR was associated with the presence of ascites and the progression in cirrhosis patients. CONCLUSIONS AGR is a potential biomarker for diagnosis of liver disease progression.

Abstract
Cerebral infarction causes secondary neurodegeneration and angiogenesis in thalamus, which impacts functional recovery after stroke. Here, we hypothesize that activation of ephrinB2 could stimulate angiogenesis and restore the secondary neurodegeneration in thalamus after cerebral infarction. Focal cerebral infarction was induced by middle cerebral artery occlusion (MCAO). Secondary damage, angiogenesis, amyloid-β (Aβ) deposits, levels of ephrinB2 and receptor for advanced glycation end product (RAGE) in the ipsilateral thalamus were determined by immunofluorescence and immunoblot. The contribution of ephrinB2 to angiogenesis was determined by siRNA-mediated knockdown of ephrinB2 and pharmacological activation of ephrinB2. The results showed that formation of new vessels and ephrinB2 expression was markedly increased in the ipsilateral thalamus at seven days after MCAO. EphrinB2 knockdown markedly suppressed angiogenesis coinciding with increased Aβ accumulation, neuronal loss and gliosis in the ipsilateral thalamus. In contrast, clustered EphB2-Fc significantly enhanced angiogenesis, alleviated Aβ accumulation and the secondary thalamic damage, which was accompanied by accelerated function recovery. Additionally, activation of ephrinB2 significantly reduced RAGE levels in the ipsilateral thalamus. Our findings suggest that activation of ephrinB2 promotes angiogenesis, ameliorates Aβ accumulation and the secondary thalamic damage after cerebral infarction. Additionally, RAGE might be involved in Aβ clearance by activating ephrinB2 in the thalamus.

Abstract
Background: The mechanism of the 308-nm excimer laser in vitiligo treatment has not yet been adequately studied. In this study, we explored the role of the 308-nm excimer laser in treatment of vitiligo and the molecular mechanisms underlying melanin biosynthesis in melanocytes after 308-nm excimer laser radiation. Materials and methods: The B16 cells were irradiated at doses of 0 mJ/cm2, 100 mJ/cm2, 300 mJ/cm2 and 600 mJ/cm2 using a 308-nm excimer laser and then cultured for an additional 24, 48 or 72 hours. Melanogenesis and tyrosinase activity in cells were measured by biochemical methods. The expression of tyrosinase, MITF, Wnt3α and β-catenin was analyzed by Western blotting. Results: Cell irradiation with the 308-nm excimer laser not only significantly elevated the melanin content (p < .01) but also stimulated the activity of tyrosinase (p < .01). The expressions of tyrosinase and MITF were also significantly increased in cells after 308-nm excimer laser irradiation. We also defined the signaling pathway by which the 308-nm excimer laser stimulates melanin biosynthesis. Increased Wnt3α and β-catenin expression was observed by Western blot analysis. Conclusion: Activation of the Wnt/β-catenin pathway likely led to the activation of MITF and tyrosinase transcription, as well as, the subsequent induction of melanin synthesis.

Abstract
Background To explore potential therapeutic target is one of the areas of great interest in both clinical and basic hepatocellular carcinoma (HCC) studies. Nuclear receptor liver receptor homolog-1 (LRH-1, NR5A2) is proved to play a positive role in several cancers including breast cancer, pancreatic cancer and intestinal cancer in recent years. However, the exact role of LRH-1 in the development and progression of HCC is not fully elucidated. Methods The LRH-1 expression level in HCC clinical samples was examined by immunohis-tochemistry (IHC). Stable LRH-1-suppressed HepG2 clones (HepG2LRH-1/-) were generated by transcription activator-like effector nucleases (TALENs) and both in vitro and in vivo experiments were conducted. Results We confirmed that LRH-1 showed an increased expression pattern in HCC clinical samples. Our in vitro and in vivo results indicated that suppression of LRH-1 in HepG2 significantly attenuated its proliferation rate and tumorigenic capacity. Gene expression microarray analysis indicated that LRH-1mostly regulated gene expression involved in cell cycle. In addition, our gain-of-function experiments indicated that ectopic expression of LRH-1 dramatically induced the mRNA and protein levels of c-myc and cyclin E1, while attenuating the expression of p21. Conclusion Our results suggest that LRH-1 might be a potential therapeutic target for clinical HCC treatment.

Abstract
With the development of the Internet, an increasing number of adolescents play online game excessively, which leads to adverse effects on individuals and society. Previous studies have demonstrated altered gray-matter volume (GMV) in individuals with Internet gaming disorder (IGD), but the relationship between the tendency to IGD and the GMV across whole brain is still unclear in adolescents. In the present study, anatomical imaging with high resolution was performed on 67 male adolescents who played online game; and Young's Internet addiction test (IAT) was conducted to test the tendency to IGD. FMRIB Software Library (FSL) was used to calculate the voxel-based correlations between the GMV and the IAT score after controlling for the age and years of education. The GMVs of the bilateral postcentral gyri (postCG), the bilateral precentral gyri (preCG), the right precuneus, the left posterior midcingulate cortex (pMCC), the left inferior parietal lobe (IPL), and the right middle frontal gyrus (MFG) were negatively correlated with the IAT score. The correlation still existed between the IAT score and the GMVs of the bilateral postCG, the left preCG, the left pMCC, and the right MFG after controlling for the total time of playing online game. When the participants were divided into two groups according to the IAT score, the GMVs of these IAT-related brain regions were lower in high IAT score subgroup (IAT score >50) than in low IAT score subgroup (IAT score ≤50). Our results suggested that the GMVs of brain regions involved in sensorimotor process and cognitive control were associated with the IGD tendency. These findings may lead to new targets for preventing and treating the IGD.

Abstract
Recent studies have shown that expression levels of different alleles at the same HLA class I locus can vary dramatically, which might have a broad influence on human disease. However, precise quantification of the relative expression level of each HLA allele is challenging, because distinguishing different alleles on the same locus is difficult. Here, we developed a series of allele-specific, real-time polymerase chain reaction assays for quantifying HLA class I allele mRNA in most Han individuals. The alleles of almost all heterozygous genotypes with a frequency higher than 0.5% in our population (78 alleles on HLA-A locus, 124 alleles on HLA-B locus, and 74 alleles on HLA-C locus) were specifically amplified. The specificity of the amplification was strictly validated by setting the corresponding negative control for each allele of each genotype. The amplification efficiency of each reaction was determined, and the slopes of the reactions were compared. This study provides a tool for detecting the comprehensive expression profile of HLA class I alleles and will be useful not only for the investigation of the molecular mechanism underlying HLA allele expression regulation but also for exploration of immunological mechanisms involving HLA expression in the fields of tumour immune evasion, viral infection, auto-immune disorders, and graft vs host disease after haematopoietic stem cell transplantation.

Abstract
We have investigated antioxidant actions of acteoside (ACT) and another natural phenylpropanoid glycoside, cistanoside F (CIS-F) on lipid peroxidation in rat liver mitochondria (RLM) and rat liver mitochondrial lipid (RLML) liposomes induced by Fe(2+)/ADP. A synthetic ACT analogue, TX-1847, was also examined. Oxygen consumption, the formation of thiobarbituric acid reactive substances (TBARs) and glutathione concentration were determined simultaneously during lipid peroxidation. The radical scavenging activity of the compounds was evaluated by using 1,1-diphenyl-2-picrylhydrazyl. ACT and its analogs produced dose-dependent inhibitions of mitochondrial and liposomal lipid peroxidation (ACT ≈ CIS-F > TX-1847). Their radical scavenging activities were ranked as follows: TX-1847 > ACT > CIS-F. ACT, CIS-F, and TX-1847 spared reduced glutathione (GSH) during mitochondrial lipid peroxidation. The radical scavenging activities of the compounds did not parallel their anti-peroxidative activities. The data are consistent with the idea that the inhibitory activities of phenylpropanoids were primarily due to a radical chain-breaking mechanism. The sugar moieties in ACT and CIS-F, and/or the conformational structure of the compounds, also seem to play an important role in their inhibitory effects on lipid peroxidation.

Abstract
The aim of this study was to evaluate prospectively cytokine levels and disease activity in juvenile idiopathic arthritis (JIA) patients treated with and without tumour necrosis factor (TNF)-α inhibitors. TNF-α inhibitor-naive JIA subjects were followed prospectively for 6 months. Cytokine levels of TNF-α, interleukin (IL)-1β, IL-6, IL-8, IL-10 and IL-17 were measured at baseline for JIA subjects and healthy controls (HCs). Cytokine levels were then measured at four time-points after initiation of TNF-α inhibition for anti-TNF-α-treated (anti-TNF) JIA subjects, and at two subsequent time-points for other JIA (non-TNF) subjects. JIA disease activity by Childhood Health Assessment Questionnaire (CHAQ) disability index/pain score and physician joint count/global assessment was recorded. Sixteen anti-TNF, 31 non-TNF and 16 HCs were analysed. Among JIA subjects, those with higher baseline disease activity (subsequent anti-TNFs) had higher baseline TNF-α, IL-6 and IL-8 than those with lower disease activity (non-TNFs) (P < 0·05). TNF-α and IL-10 increased, and IL-6 and IL-8 no longer remained significantly higher after TNF-α inhibitor initiation in anti-TNF subjects. Subgroup analysis of etanercept versus adalimumab-treated subjects showed that TNF-α and IL-17 increased significantly in etanercept but not adalimumab-treated subjects, despite clinical improvement in both groups of subjects. JIA subjects with increased disease activity at baseline had higher serum proinflammatory cytokines. TNF-α inhibition resulted in suppression of IL-6 and IL-8 in parallel with clinical improvement in all anti-TNF-treated subjects, but was also associated with elevated TNF-α and IL-17 in etanercept-treated subjects.

Abstract
OBJECTIVE Rising anti-double-stranded (ds) DNA titers have been shown by some, but not all, studies to be predictive of disease flares in systemic lupus erythematosus (SLE). We hypothesized that a rapid and substantial rise in anti-dsDNA titer (anti-dsDNA surge) would be a good predictor of a clinically important SLE flare. METHODS A matched case-control study was conducted in an academic rheumatology practice setting. Our primary endpoint was the occurrence of a severe SELENA-SLEDAI (SS) flare within six months of an anti-dsDNA surge, and secondary endpoints were mild/moderate SS flares, as well as BILAG A and B renal flares. Cases were identified as those patients whose disease course included a surge of anti-dsDNA, defined as an increase of anti-dsDNA titer by the Crithidia luciliae immunofluorescence (CLIF) assay from 0 to 3+/4+, or from 1+ to 4+, within a period of less than 12 months. The date of the anti-dsDNA surge was defined as Day 0. Two control SLE patients were identified for each case and were matched for age, sex, race, and visit date closest to case Day 0, but without an anti-dsDNA surge. Logistic regression models were used to detect associations between anti-dsDNA surges and severe SS flares. RESULT A higher proportion of cases, compared to controls, experienced a severe SS flare within six months of Day 0 (OR 6.3 (95% confidence intervals 2.0-19.9), p = 0.02). Associations with all flares and hospitalizations for flares were also observed. However, an anti-dsDNA surge was not predictive of a renal flare. CONCLUSION An anti-dsDNA surge predicts the subsequent development of a severe SS flare within six months. Physicians should closely monitor such patients and treat promptly at the first sign of clinical activity.

Abstract
HLA-G and HLA-E are nonclassical human MHC class I molecules, which promote tolerance to NK cytotoxicity. MICA and MICB are known to enhance the functions of NK and T cells. However, the expression of these molecules has never been investigated in liver cancer. Using RT-PCR and western blot, we aimed to identify the expression of HLA-G, HLA-E, MICA and MICB in a panel of 41 tissues dissecting from liver cancer patients in China. HLA-G mRNA was expressed in 8 of 41 Human Hepatocellular Carcinoma (HCC) specimens and in 1 adjacent normal hepatocellular tissue. The expression of HLA-G protein was found in 7 of the 8 HLA-G mRNA-positive HCC tissues. HLA-E mRNA was up-regulated in 56% HCC specimens but the expression of HLA-E protein was only upregulated in 29% HCC tissues in comparison with their adjacent normal counterpart. MICA and MICB mRNA was decreased in 5% and 8% HCC specimens, while the expression of their proteins decreased in 21% and 24% HCC tissues. These results suggested that the expressions of HLA-G, HLA-E, MICA and MICB were differently up-regulated in HCC tissues. Furthermore, HLA-E and MICA/B genes showed obviously distinctive expression pattern at transcription and translation level.

Abstract
The infra-red (IR) spectroscopic data for a series of 28 homoleptic substituted bis(naphthalocyaninato) rare-earth complexes M(2,3-Nc*)2 [M = Y, La–Lu except Pm; H2Nc* = 3(4),12(13),21(22),30(31)-tetra(tert-butyl)-2,3- naphthalocyanine (H2TBNc) and 3,4,12,13,21,22,30,31-octa(dodecylthio)-2,3-naphthalocyanine (H2ODTNc)] have been collected with a resolution of 2 cm–1. These neutral sandwich complexes are radicals due to their composition (Nc*)2–MIII(Nc*)–, wherein the unpaired electron is delocalized over both macrocycles on the vibrational time scale. Compared to spectra obtained with low resolution, such as 4 cm–1, a larger number of vibrational modes could be distinguished. The IR spectra for M(ODTNc)2 are much simpler than those of M(TBNc)2, revealing the relatively higher symmetry of the former molecules. By analogy with bis(phthalocyaninato) rare-earth counterparts, the pyrrole stretching absorptions at 1314–1317 and 1323–1330�cm–1 for M(TBNc)2 and at 1316–1327 cm–1 for M(ODTNc)2 are assigned to the IR marker bands of the respective naphthalocyanine mono-anion radicals. These marker bands, together with those at 746–753 cm–1 assigned to C–H wagging, 1350–1355 cm–1 attributed to pyrrole stretchings, and 1389–1394 cm–1 due to naphthalene stretchings, have been found to shift slightly to higher energy along with the rare-earth contraction, clearly demonstrating the effect of rare-earth ionic radius.

Abstract
The author studies the enzyme immunosensor made up of graphite electrode and protein film of regenerated silk fibroin which is employed to immobilized antigen (rabbit IgG). IgG will be recognized and combined by antibody (goat-anti-rabbit IgG-HRP). After enlarging the signal of the combination of antigen and antibody by H2O2, the concentration of IgG is able to be measured by testing the electrode potential directly. The Enzyme Immunosensor is sensitive when measuring IgG and the detection limit of 1.2 x 10(-10) mol/L is found. It shows linear response over the concentration range of 4.1 x 10(-7)-1.2 x 10(-10) mol/L. Electrophoresis cuts down the time of antibody-antigen interaction from 90 min to 30 min. The response time is 15 s. Enzyme immunosensor with better stability and higher sensitivity can be used extensively in clinical diagnosis, medical and environmental studies, HLA molecular diagnosis and so on.

Abstract
The molecular basis of obligate anaerobiosis is not well established. Bacteroides thetaiotaomicron is an opportunistic pathogen that cannot grow in fully aerobic habitats. Because microbial niches reflect features of energy-producing strategies, we suspected that aeration would interfere with its central metabolism. In anaerobic medium, this bacterium fermented carbohydrates to a mixture of succinate, propionate and acetate. When cultures were exposed to air, the formation of succinate and propionate ceased abruptly. In vitro analysis demonstrated that the fumarase of the succinate-propionate pathway contains an iron-sulphur cluster that is sensitive to superoxide. In vivo, fumarase activity fell to < 5% when cells were aerated; virtually all activity was recovered after extracts were chemically treated to rebuild iron-sulphur clusters. Aeration minimally affected the remainder of this pathway. However, aeration reduced pyruvate:ferredoxin oxidoreductase (PFOR), the first enzyme in the acetate fermentation branch, to 3% of its anaerobic activity. This cluster-containing enzyme was damaged in vitro by molecular oxygen but not by superoxide. Thus, aerobic growth is precluded by the vulnerability of these iron-sulphur cluster enzymes to oxidation. Importantly, both enzymes were maintained in a stable, inactive form for long periods in aerobic cells; they were then rapidly repaired when the bacterium was returned to anaerobic medium. This result explains how this pathogen can easily recover from occasional exposure to oxygen.

Abstract
OBJECTIVES To explore the therapeutic methods for hypoxia and cold induced blood vessel damage by observing the changes of NO synthase (NOS) activity in hypoxia and development of coldm induced blood vessels damage, and studying the effects of SOD and vitamin C on the changes of NOS activity. METHODS The main artery was isolated from Wistar rats and exposed to hypoxia and/or cold environment in vitro. LDH activity was measured using an automatic biochemical analyzer and NOS and SOD activities in blood vessels were analyzed respectively by Griess assay and adrenaline autoxidantion method. RESULTS NOS activity in hypoxia, cold and hypoxia-cold damaged vessels decreased by 18.2%, 19.1% and 25.9% respectively after exposure as compared with the control vessels. The changes of NOS activity were time dependent. The NOS activity in damaged vessels was negatively correlated with LDH activity in the culture medium of the respective vessels. The SOD activity in hypoxia and/or cold damaged vessels also decreased significantly. Giving SOD (200 u/ml) or vitamin C (50 mg/ml) immediately after hypoxia and/or cold exposure increased the NOS activity and SOD activity in the damaged vessels significantly, as compared with the non-treatment controls. CONCLUSIONS The decrease of NOS activity is closely related to the development of damage induced by hypoxia and/or cold injury. SOD and vitamin C could protect the blood vessels exposed to hypoxia and/or cold from damage, possibly by increasing NOS activity.

Abstract
The undergraduate dental curriculum is undergoing rapid change and revision in dental schools worldwide. Decreasing edentulism, the advent of the clinical dental technician, and advances in technology (such as dental implantology) have led to changes in patient management and treatment options for general dental practitioners in New Zealand. The current undergraduate removable prosthodontic curriculum has seen very little change in past years at the School of Dentistry, University of Otago, and is under review to facilitate the teaching of general dental practice in the Final Year. A questionnaire-based survey of 150 general dental practitioners (response rate 74.6 percent) supported modification of the existing removable prosthodontics curriculum to improve its relevance to modern general dental practice. Integration of fixed and removable prosthodontic teaching was recommended.

Abstract
Phase variation in colony morphology has been associated with the pathogenesis of infection caused by Haemophilus influenzae. This study shows that differences in colony opacity in non-typeable H. influenzae (NTHi) strain H233 involve phase changes in the lipopolysaccharide (LPS) and depend on the expression of licl and lic2, which contain translational switches based on intragenic tandem repeats of 5'-CAAT-3'. Genetic analysis showed that opaque organisms have an out-of-frame number of repeats in both licl, required for the expression of phosphorylcholine (ChoP), and lic2, a putative galactosyl transferase that adds the terminal galactose on Galalpha1-4Gal. Defined variants in these loci were used to examine the contribution of individual LPS structures to resistance to serum bactericidal activity mediated by antibody and C-reactive protein (CRP). The addition of ChoP by licl was the only factor in serum killing involving CRP and complement. The terminal galactose moiety, in contrast, conferred resistance to killing by naturally acquired antibody and complement present in human serum. As Galalpha1-4Gal is also found on human glycolipids, it appears that decoration of the cell surface with this host-like antigen blocks antibody-mediated serum bactericidal activity. Genetic analysis of NTHi within the human respiratory tract demonstrated that Galalpha1-4Gal may not be expressed during carriage but may be advantageous for the organism in inflammatory states such as pneumonia.

Abstract
Phosphorylcholine (ChoP) is a component of the teichoic acids of Streptococcus pneumoniae and has been recently identified on the lipopolysaccharide of Haemophilus influenzae, also a major pathogen of the human respiratory tract. Other gram-negative pathogens that frequently infect the human respiratory tract were surveyed for the presence of the ChoP epitope as indicated by binding to monoclonal antibodies (MAbs) recognizing this structure. The ChoP epitope was found on a 43-kDa protein on all clinical isolates of Pseudomonas aeruginosa examined and on several class I and II pili of Neisseria meningitidis. The specificity of the anti-ChoP MAb was demonstrated by the inhibition of binding in the presence of ChoP but not structural analogs. As in the case of H. influenzae, the expression of this epitope was phase variable on these species. In P. aeruginosa, this epitope was expressed at detectable levels only at lower growth temperatures. Expression of the ChoP epitope on piliated neisseriae displayed phase variation, both linked to pilus expression and independently of fully piliated bacteria.

Abstract
Haemophilus influenzae undergoes phase variation in expression of the phosphorylcholine (ChoP) epitope, a structure present on several invasive pathogens residing in the human respiratory tract. In this study, structural analysis comparing organisms with and without this epitope confirmed that variants differ in the presence of ChoP on the cell surface-exposed outer core of the lipopolysaccharide. During nasopharyngeal carriage in infant rats, there was a gradual selection for H. influenzae variants that express ChoP. In addition, genotypic analysis of the molecular switch that controls phase variation predicted that the ChoP+ phenotype was predominant in H. influenzae in human respiratory tract secretions. However, ChoP+ variants of nontypable H. influenzae were more sensitive to the bactericidal activity of human serum unrelated to the presence of naturally acquired antibody to ChoP. Serum bactericidal activity required the binding of C-reactive protein (CRP) with subsequent activation of complement through the classical pathway. Results of this study suggested that the ability of H. influenzae to vary expression of this unusual bacterial structure may correlate with its ability both to persist on the mucosal surface (ChoP+ phenotype) and to cause invasive infection by evading innate immunity mediated by CRP (ChoP- phenotype).

Abstract
In the reconstruction of the concha, standing support was necessary. From 1984 to 1996, 33 cases of aurical defects were admitted. Three standing-materials were chosen, and they included carved autogenous cartilage, heterogenous concha cartilage and steel wire work silicon-wires with silastic rubber tube. After expansion of the postauricular skin by tinsion expander, the standing-material was enveloped and total ear reconstruction or repair was performed. After followed up for average of 3.5 years, of the twenty-two cases, 16 had a satisfactory result, unsatisfied in 3 and failure in 3. It was concluded that the outcome of autogenous concha cartilage as a standing-material was good. The other two materials if used should be very carefully.

Abstract
The protein p25 open reading frame (ORF) of beet necrotic yellow vein virus-BNYVV RNA3 was cloned into bacterial expression vector downstream of the 5-'terminus part of beta-galactosidase ORF and the expressed p25 fusion protein was used to produce an antiserum. The latter was employed to detect the subcellular location of p25 in mechanically inoculated Tetragonia expansa, Chenopodium quinoa and sugarbeet leaves by Western blot assay. The results showed that p25 was present as a soluble protein only in the S30 fraction of T. expansa, C. quinoa and sugarbeet leaves infected with BNYVV.

Abstract
Estrogen affects the synthesis and release of several pituitary hormones. The estrogen receptor (ER), a member of the steroid hormone receptor family, is thought to mediate transcriptional effects in a cell-specific fashion. We investigated whether ER is expressed in specific hormone-producing cell types in the human pituitary and its adenomas. Pituitary adenomas (n = 34) were collected at the time of surgery, and normal glands were obtained from autopsy. Expression of ER messenger ribonucleic acid (mRNA) was determined by reverse transcription-polymerase chain reaction (RT-PCR) and in situ hybridization. ER was also localized with immunohistochemistry and protein extraction. By RT-PCR, ER mRNA was found in the nontumorous pituitary and in pituitary adenomas expressing only PRL, in those producing GH and PRL, and in adenomas expressing the gonadotropic hormones. No ER mRNA was detected in adenomas expressing only GH without PRL or gonadotropins, nor in tumors producing ACTH without PRL or gonadotropins. In situ hybridization was not as sensitive or specific as RT-PCR. Biochemical analysis performed on seven tumors that were positive for ER mRNA by RT-PCR detected ER protein in only one PRL adenoma and one oncocytoma and yielded negative or equivocal results in one PRL adenoma, three GH-PRL adenomas, and one null cell adenoma. ER protein was localized by immunohistochemistry in scattered cells of the nontumorous adenohypophysis and in a few PRL and gonadotroph adenomas. We conclude that ER expression, as determined by RT-PCR, correlates with the expression of PRL or gonadotropins; in contrast, ER mRNA was not detected in adenomas that express only GH or ACTH. These findings implicate ER as a cell-specific transcription factor that may regulate cytodifferentiation in the pituitary.

Abstract
Clonality studies have suggested that neoplasms are monoclonal and hyperplasias are polyclonal. To investigate this question in thyroid, we analyzed the clonality of 26 morphologically characterized hyperplastic nodules from 19 patients with sporadic goiters. For comparison we studied six thyroid carcinomas. We used the highly informative M27 beta probe that maps to the X-chromosome DXS255 locus (X cen-p11.22). Material was obtained from 52 nodules; tissue from nine nodules was rejected because of contamination with normal elements, five patients (eight nodules) were homozygous at Pst I sites in nonnodular thyroid tissue, and three nodules were excluded for technical reasons. Methylation patterns after Hpa II digestion confirmed polyclonality in all nontumorous thyroids of informative patients. Seven hyperplastic nodules were polyclonal, and 18 were monoclonal; one showed loss of heterozygosity. One nodule exhibited aberrant methylation. Multiple nodules were obtained from four patients; in three, all were monoclonal with activation of the same allele. Three papillary carcinomas were monoclonal; two exhibited aberrant methylation. One follicular carcinoma showed loss of heterozygosity. Our data indicate that morphologically indistinguishable hyperplastic thyroid nodules may be monoclonal or polyclonal. These findings suggest that variable molecular mechanisms are involved in the pathogenesis of nodules in sporadic goiter. Future studies will need to explore the biological significance of nodules of variable clonal origin.

Abstract
In 15 patients with essential hypertension, 16 patients with renal hypertension and in 12 healthy subjects Ca2+ ATPase activity was determined in red blood cells both in the basal state and after maximal stimulation with calmodulin. Normal subjects showed a basal and maximal activity of 7.1 +/- 3.6 and 16.0 +/- 2.3 pmol phosphate/min.10(6) RBC, respectively. Renal hypertensives had a similar basal Ca2+ ATPase activity (5.4 +/- 4.1 pmol phosphate/min.10(6) RBC) and a lowered maximal Ca2+ ATPase activity (9.8 +/- 5.4 pmol phosphate/min.10(6) RBC, p < 0.05). In essential hypertensives basal and maximal Ca2+ ATPase activity was 9.0 +/- 5.3 and 35.4 +/- 14.4 pmol phosphate/min.10(6) RBC, respectively, the latter being significantly increased (p < 0.01). This finding, which is in contrast to earlier results indicating a lowered Ca2+ ATPase activity in essential hypertension, may be explained as a consequence of an increased Ca2+ influx in essential hypertension. A lowered Ca2+ ATPase activity does not seem to be involved in the pathogenesis of essential hypertension.

Abstract
Sera from 130 first trimester pregnant women were tested for their serum antibody level against a naturally occurring serum antigen purified from non-pregnancy sera. IgG and IgM antibody level was measured using enzyme linked immunosorbent assay. Results indicate that patients with multiple abortion (n = 26) have significantly (p = 0.0029) lower level of IgG antibody and significantly (p = 0.0001) higher level of IgM antibodies against the serum antigen as compared to the patients with successful pregnancies with no history of miscarriage (n = 63). Western blot analysis identified the serum antigen recognized by the IgM antibody as a 24 kDa molecular mass component. These IgG and IgM antibodies may play an important role in the outcome of pregnancy.
