Abstract
Adult-onset Still's disease (AOSD) is a rare autoinflammatory disease with systemic involvement, and its pathophysiology remains unclear. Genome-wide association studies (GWAS) in the Chinese population have revealed an association between AOSD and the major histocompatibility complex (MHC) locus; however, causal variants in the MHC remain undetermined. In the present study, we identified independent amino-acid polymorphisms in human leukocyte antigen (HLA) molecules that are associated with Han Chinese patients with AOSD by fine-mapping the MHC locus. Through conditional analyses, we identified position 34 in HLA-DQα1 (p = 1.44 × 10-14) and Asn in HLA-DRβ1 position 37 (p = 5.12 × 10-11) as the major determinants for AOSD. Moreover, we identified the associations for three main HLA class II alleles: HLA-DQB1*06:02 (OR = 2.70, p = 3.02 × 10-14), HLA-DRB1*15:01 (OR = 2.44, p = 3.66 × 10-13), and HLA-DQA1*01:02 (OR = 1.97, p = 1.09 × 10-9). This study reveals the relationship between functional variations in the class II HLA region and AOSD, implicating the MHC locus in the pathogenesis of AOSD.

Abstract
INTRODUCTION To assess the clinical performance and correlations of automated chemiluminescence assay (CIA) and enzyme-linked immunosorbent assay (ELISA) for detecting antiphospholipid (aPL) antibodies in the diagnosis of antiphospholipid syndrome (APS). METHODS The study recruited 505 subjects, including 192 with APS, 193 with connective tissue diseases other than APS, and 120 healthy donors. We measured anticardiolipin (aCL) and anti-β2-glycoprotein I (anti-β2GPI) antibodies IgG, IgM, and IgA in all the samples using both CIA and ELISA. RESULTS Total agreement between the two methods ranged from 83.50% for anti-β2GPI IgG antibodies to 92.76% for anti-β2GPI IgM antibodies in all the groups. Anti-β2GPI and aCL IgG assays showed the highest Spearman's rho coefficients (anti-β2GPI IgG = 0.742, aCL IgG = 0.715). Anti-β2GPI IgG CIA showed the highest sensitivity for diagnosis of APS at 80.21%, which was significantly higher than the sensitivity of anti-β2GPI IgG ELISA (52.08%). For diagnosis of APS, anti-β2GPI IgG CIA had the best discrimination power with the area under the curves (AUC) of 0.922, followed by aCL IgG CIA (AUC of 0.905). While the CIA AUC was slightly higher in all cases, the difference was not statistically significant. CONCLUSION CIA measurements had a good agreement and correlation with comparative ELISA assays. The CIA anti-β2GPI IgG however was significantly more sensitive for APS diagnosis. The two assay methodologies showed comparable predictive powers and support the value of the CIA method for improved diagnosis and management of patients with APS.

Abstract
OBJECTIVES As a rare systemic autoinflammatory disease, adult-onset Still's disease (AOSD) has heterogeneous clinical manifestations, response to treatment and outcome. This study tried to assess the clinical characteristics, laboratory tests, and treatments of Chinese AOSD patients, and make a retrospective analysis. METHODS We collected from 7 hospitals in China a total of 517 Chinese patients with AOSD who satisfied the Yamaguchi criteria. We retrospectively evaluated their clinical features, laboratory tests, treatments and compared them with published data from different studies. All the data in this study were from medical records and further statistic analyses. RESULTS We evaluated a total of 517 AOSD patients, 72% female, average age of onset was 37.7; spiking fever, rash and arthralgia occurred in 472 (91.3%), 413 (79.9%), 378 (73.1%) cases, respectively. There were 439/513 (85.6%) cases with leukocytosis and 456/476 (95.8%) cases with raised serum ferritin. The highest frequently used medications and regimens for remission were glucocorticoids (498/517, 96.3%), methotrexate (273/517, 52.8%) and hydroxychloroquine (174/517, 33.7%). 84.4%. 357/423 of AOSD cases were able to achieve initial remission with different regimens, mostly including glucocorticoids, methotrexate or hydroxychloroquine. 47.2% of them (244/517) received 30<D≤60 mg/d of prednisone to reach final clinical remission. Further analysis indicated that risk factors, such as skin rash, pericarditis, splenomegaly and delayed diagnosis, are highly related to the dosage of prednisone for remission. CONCLUSIONS Glucocorticoids are mostly selected to induce remission in China and half of them required ~0.5-1mg/kgbw prednisone. In patients with skin rash, pericarditis, splenomegaly or delayed diagnosis, a higher dosage of prednisone was needed to obtain remission.

Abstract
Objective: To investigate the caring burden and its determinants of primary informal caregiver of patients with chronic wound. Approach: A prospective cross-sectional study of 132 pairs of chronic wound care recipients and their informal caregivers was included. The characteristics of patients and their informal caregivers as well as caregiver burden assessment by the caregiver burden inventory (CBI) were measured. Single factor analysis and multiple regression analysis were carried out to explore the independent determinants of caregiver burden on caring for patients with chronic wound. Results: Most of the caregivers were female with mean age of 54.57 ± 13.35 years, and 58.3% of the caregivers were adult children. The mean CBI score was 34.21 ± 9.69 at a medium level. The following variables increased the CBI scores of caregivers: long caring time per day for patients, powerlessness status of patients, insufficient self-efficacy, and social support of caregivers, the model was able to explain 67.5% of variance in caregiver burden (F = 47.167, p = 0.000, R 2 = 0.675, adjusted R 2 = 0.660). Innovation: Caring burden of patients with chronic wound as a key consideration of patient-centered wound care has received relatively little attention. In this study we report the status of caring burden and reveal its determinants of primary informal caregiver of patients with chronic wound. Conclusion: Wound professionals are suggested to pay attention to the caregiver burden of patients with chronic wound and develop family-centered intervention support service system according to the determinants of caregiver burden to alleviate the caregiver burden.

Abstract
The burden of obesity and associated cardiometabolic diseases has been considered as an important risk factor for lupus patients. Therefore, whether obesity is involved in the over-activation of autoimmune response has attracted more and more attention. Hydroxychloroquine is a synthetic antimalarial drug and has been the clinical treatment of rheumatic diseases irreplaceable first-line drugs. Hydroxychloroquine has been suggested to have beneficial effects on lipids and insulin sensitivity, which may contribute in lowering high cardiovascular risk in SLE patients. However, its mechanism on insulin sensitivity and lipid disorders is far from being completely understood. In the present study, the therapeutic effects of hydroxychloroquine were evaluated under pathological conditions in vivo. Obesity was induced in C57BL/6 mice fed with high-fed diet, or in mice fed with high-fat diet and hydroxychloroquine. In addition, healthy mice that received normal chow diet were also monitored. The present results revealed that hydroxychloroquine reduced weight, hepatic steatosis, glucose, and insulin resistance. Furthermore, hydroxychloroquine downregulated the expression of peroxisome proliferator-activated receptor gamma in the liver. According to these present results, genes about lipid metabolism went down in high-fat mice liver. Hydroxychloroquine shows potential in ameliorating obesity-induced pathology, which acts though PPARγ to facilitate the healthy function of hepatic tissues. This evidence shows that hydroxychloroquine plays a role in improving obesity-induced lipotoxicity and insulin resistance though the peroxisome proliferator-activated receptor gamma pathway.

Abstract
BACKGROUND The aim of the study was to determine the prevalence and clinical associations of antiphosphatidylserine/prothrombin antibodies (aPS/PT) with thrombosis and pregnancy loss in Chinese patients with antiphospholipid syndrome (APS) and seronegative APS (SNAPS). METHODS One hundred and eighty six Chinese patients with APS (67 primary, 119 secondary), 48 with SNAPS, 176 disease controls (79 systemic lupus erythematosus [SLE], 29 Sjogren's syndrome [SS], 30 ankylosing spondylitis [AS], 38 rheumatoid arthritis [RA]) and 90 healthy donors were examined. IgG and IgM aPS/PT, IgG/IgM/IgA anticardiolipin (aCL) and IgG/IgM/IgA anti-β2-glycoprotein I (anti-β2GPI) antibodies were tested by ELISA. RESULTS One hundred and sixty (86.0%) of APS patients were positive for at least one aPS/PT isotype. One hundred and thirty five (72.6%) were positive for IgG aPS/PT, 124/186 (66.7%) positive for IgM aPS/PT and 99 (53.2%) positive for both. Approximately half of the SNAPS patients were positive for IgG and/or IgM aPS/PT. Highly significant associations between IgG aPS/PT and venous thrombotic events (odds ratio [OR]=6.72) and IgG/IgM aPS/PT and pregnancy loss (OR=9.44) were found. Levels of IgM aPS/PT were significantly different in APS patients with thrombotic manifestations and those with fetal loss (p=0.014). The association between IgG/IgM aPS/PT and lupus anticoagulant (LAC) was highly significant (p<0.001). When both were positive, the OR for APS was 101.6. Notably, 91.95% (80/87) of LAC-positive specimens were positive for IgG and/or IgM aPS/PT, suggesting aPS/PT is an effective option when LAC testing is not available. CONCLUSIONS Anti-PS/PT antibody assays demonstrated high diagnostic performance for Chinese patients with APS, detected some APS patients negative for criteria markers and may serve as potential risk predictors for venous thrombosis and obstetric complications.

Abstract
To estimate the mortality and describe the causes of death in a large multicenter cohort of hospitalized patients with SLE in China. This was a retrospective study of a nationwide SLE cohort (10 centers, 29,510 hospitalized patients) from 2005 to 2014 in China. Standardized mortality ratios (SMRs) were calculated for all death and were stratified by sex and age. Chi-square test was used to determine whether the major causes of death vary in age, sex, duration of SLE, disease activity, or medications. Comparison between dead patients and survival controls was used to identify the risk factors for mortality. Logistic regression analysis was used to evaluate the risk factors for mortality. A total of 360 patients died during the study period, accounting for 1.22%. The overall SMR was 2.13 (95% CI 1.96, 2.30), with a particularly high SMR seen in subgroups characterized by younger age. Infection (65.8%) was the most common cause of death, followed by lupus nephritis (48.6%), hematological abnormality (18.1%), neuropsychiatric lupus/NPSLE (15.8%), and interstitial pneumonia (13.1%). Cardiovascular disease and malignancy contributed little to the causes of death. Infection, in particular severe pulmonary infection, emerged as the foremost risk factor for mortality, followed by lupus encephalopathy. However, lupus nephritis and hematological abnormalities occurred more frequently in survival patients. SLE patients at a younger age of diagnosis have a poorer prognosis. Infection dominated the causes of death in recent China. Ethnicity and medications might account for the differences in causes of death compared with western populations.

Abstract
The objectives of this study were to translate the powerlessness assessment tool (PAT) into Chinese, and to evaluate its psychometric performance. The PAT was translated into Chinese and was evaluated in patients with chronic wounds. Mean PAT scores were compared between various wound types to evaluate the scale's power to differentiate wound severity (PUSH score). There were 154 consecutive patients included in this study. All items were included, and the results of item-domain correlation (r ranged from 0.838 to 0.967) and small-group analysis (critical ratio, p < 0.05) were satisfactory. Furthermore, the Chinese PAT also showed good criterion validity when correlated with the Cardiff wound impact schedule (r = 0.726, p < 0.01). Exploratory factor analysis of these items extracted only two domains instead of the hypothesized three domains: self-perception of behavioral control and decision making (9 items) and emotional responses to perceived control (3 items), explained 82.045% of the variance. Sensitivity was demonstrated between patients with different activity of daily living, wound severity (PUSH score) and wound types. The internal consistency of all scales of the Chinese PAT was consistently high (Cronbach's alpha ranged from 0.939 to 0. 965) and split-half reliability was 0.901. In conclusion, the validated Chinese PAT has good psychometric properties, and may be used to objectively evaluate the powerlessness experience of Chinese patients with chronic wounds.

Abstract
To investigate the information of chronic wounds, especially in the aspect of microbiological profile and to explore the relationship between the wound culture result and chronic wounds infection, we retrospectively reviewed the medical records of 107 patients with chronic wounds from January 2011 to December 2013. The sociodemographic data, wound-related information, therapeutic type, and wound infection status were extracted. Microbial specimens were obtained and processed using standard hospital procedure for wound culture. The predominant pathogen isolated was Staphylococcus aureus (n = 11, 26.2%), followed by Escherichia coli (n = 6, 14.3%), Enterobacter cloacae (n = 3, 7.1%), and Pseudomonas aeruginosa (n = 3, 7.1%). Sixty percent of the infectious chronic wounds had positive culture, and 96.2% of the noninfectious wounds had negative culture. In conclusion, the microbial characteristics were mostly in the site of lower extremity, gram-negative bacteria, and monopathogen, respectively. Furthermore, the relationship between the wound culture result and chronic wound infection was not exactly coincident. It may be useful for guiding the empiric therapy of chronic wounds.

Abstract
Hypocretin neurons in the lateral hypothalamus, a new wakefulness-promoting center, have been recently regarded as an important target involved in endogenous adenosine-regulating sleep homeostasis. The GABAergic synaptic transmissions are the main inhibitory afferents to hypocretin neurons, which play an important role in the regulation of excitability of these neurons. The inhibitory effect of adenosine, a homeostatic sleep-promoting factor, on the excitatory glutamatergic synaptic transmissions in hypocretin neurons has been well documented, whether adenosine also modulates these inhibitory GABAergic synaptic transmissions in these neurons has not been investigated. In this study, the effect of adenosine on inhibitory postsynaptic currents (IPSCs) in hypocretin neurons was examined by using perforated patch-clamp recordings in the acute hypothalamic slices. The findings demonstrated that adenosine suppressed the amplitude of evoked IPSCs in a dose-dependent manner, which was completely abolished by 8-cyclopentyltheophylline (CPT), a selective antagonist of adenosine A1 receptor but not adenosine A2 receptor antagonist 3,7-dimethyl-1-(2-propynyl) xanthine. A presynaptic origin was suggested as following: adenosine increased paired-pulse ratio as well as reduced GABAergic miniature IPSC frequency without affecting the miniature IPSC amplitude. Further findings demonstrated that when the frequency of electrical stimulation was raised to 10 Hz, but not 1 Hz, a time-dependent depression of evoked IPSC amplitude was detected in hypocretin neurons, which could be partially blocked by CPT. However, under a higher frequency at 100 Hz stimulation, CPT had no action on the depressed GABAergic synaptic transmission induced by such tetanic stimulation in these hypocretin neurons. These results suggest that endogenous adenosine generated under certain stronger activities of synaptic transmissions exerts an inhibitory effect on GABAergic synaptic transmission in hypocretin neurons by activation of presynaptic adenosine A1 receptors, which may finely regulate the excitability of these neurons as well as eventually modulate the sleep-wakefulness.

Abstract
Capillary electrophoresis with electrochemical detection (CE-ED) was employed to analyze isoflavones in red clover (Trifolium pratense). The effects of potential of working electrode, pH and concentration of running buffer, separation voltage and injection time on CE-ED were investigated. Operated in a wall-jet configuration, a 300 microm diameter carbon-disk electrode was used as the working electrode, which exhibits a good response at +0.85 V (versus saturated calomel electrode) for the analytes. The analytes could be separated in a 50 mmol/l borate buffer (pH 9.5) within 25 min. The response was linear over three orders of magnitude with detection limit (S/N=3) ranging from 2x10(-5) mg/ml to 5x10(-5) mg/ml for the analytes. This method has been used for the determination of daidzein, genistein and biochanin A in red clover with satisfactory results.

Abstract
Disialoganglioside GD2 is widely expressed among neuroblastomas, melanomas, small-cell lung carcinoma, sarcomas and brain tumors. Immunity directed against this antigen may have anti-tumor utility. Since GD2 is poorly immunogenic, anti-idiotypic antibodies may serve as alternative tumor vaccines. Monoclonal antibody 3F8, a murine IgG3 specific for GD2, has shown excellent tumor-targeting ability in vitro and in vivo. LOU/CN rats were immunized with 3F8 and their spleens were used in somatic-cell hybridization, using SP2/0, P3 and Y3 as fusion partners. Six anti-idiotypic (anti-id) MAbs (C2D8, Idio-2, AIG4, C2H7, C4E4, A2A6) were selected based on their reactivity with 3F8 and non-reactivity with murine IgG3 myelomas. Specificity of each anti-id was demonstrated by using various ELISA: (i) lack of direct binding to solid phase myelomas and serum proteins; (ii) inability of other myelomas to inhibit anti-id binding to 3F8; (iii) absence of cross-reactivity of other myelomas to solid-phase anti-id; (iv) lack of inhibition by anti-id of binding of other ganglioside antibodies to their antigens. Antigen specificity was further examined by inhibition of binding of 3F8 to GD2 on immuno-thin-layer chromatography, and by inhibition of 3F8 immunostaining of neuroblastoma cell lines. These 6 antibodies were demonstrated to be distinct, in view of their cross-reactivity, fusion partners and relative strength of binding to 3F8. Anti-GD2 antibodies were induced after immunization with these anti-id antibodies in C57Bl/6 mice. These rat anti-3F8-idiotypic antibodies with exquisite specificity for anti-GD2 antibodies may be useful in vaccine construction.

Abstract
Murine monoclonal antibody (MAb) 3F8 was previously shown to react with disialoganglioside GD2, but not with GD3, GT1b, GD1b, GD1a, GM1, GM3 and GM4. However, when the base-treatment step was ommitted from the standard neuroblastoma ganglioside extraction procedure, immuno-thin-layer-chromatography (ITLC) using 3F8 and other anti-GD2 MAbs revealed a new ganglioside band, abbreviated as NG (Rf 0.342) besides GD2 (R 0.183). It migrated below GD3 (Rf 0.358) on high-performance (HP) TLC plate and its binding to 3F8 on ITLC could be inhibited by rat anti-3F8 idiotypic antibody Idio-2, while the binding of GD2 to MAb 3F8 was not affected. Immunochemical analysis showed that this new neuroblastoma ganglioside contained alkali-sensitive O-acetylated sialic-acid residues recognized by MAb DI.I. After base treatment, its subsequent identity on ITLC was confirmed to be GD2. Lactonization of GD2 yielded 2 major bands, with Rf values (0.401, 0.583) distinct from that of the new ganglioside band. In addition, MAb DI.I did not bind to any of these GD2 lactones. Of 15 anti-GD2 MAbs studied, 13 reacted strongly with the novel ganglioside NG. By ITLC, this NG was found in ganglioside extracts of fresh surgical tumor specimens (4/4 neuroblastomas, I/I schwannoma and I/I anaplastic astrocytoma), and nude mice/rat xenografts (2/2 neuroblastomas, 2/2 osteogenic sarcomas). These data provided the first evidence that O-acetylated GD2 is a naturally occurring ganglioside derivative in human tumors and that it could cross-react with most anti-GD2 antibodies.

Abstract
A monoclonal antibody, Hepama-1, produced by immunizing mice with cells of a human hepatocellular carcinoma cell line, has been used to identify and characterize a previously unreported antigen present on the surface of human hepatocellular carcinoma cells. The antigen occurred on the membranes of human hepatoma cell lines and tumor biopsies but was not detectable in tumors of other origin or normal tissues. Binding was determined by enzyme-linked immunoabsorbent assay and immunofluorescence on cell lines and by immunoperoxidase staining of tissue sections. In immunofluorescence studies, Hepama-1 antibodies stained five out of six human hepatoma cell lines, showed only slight binding to breast tumor cell lines, but failed to stain colon tumor or normal cell lines. The antihepatoma antibody exhibited positive immunoperoxidase staining of human liver tumor sections but did not stain tumors of other origin. Hepama-1 bound specifically to a membrane glycoprotein with an approximate molecular weight of 43,000. Western blot and solid phase enzyme-linked immunoabsorbent assay analysis showed that the 43-kD antigen occurred on five of six human hepatoma cell lines and was expressed by every human hepatocellular carcinoma biopsy tested. This cell surface molecule represents a potentially useful target for immunotherapy and localization of human hepatocellular carcinomas.

Abstract
The gangliosides of human hepatoma biopsies, human hepatoma cell lines, and diethylnitrosamine-induced rat hepatomas were examined. These malignant tissues all expressed increased content of disialolactosylceramide (GD3) with respect to their normal counterparts. During the induction of rat hepatoma by diethylnitrosamine, an increase in GD3 levels appeared as early as 12 wk after initiation of diethylnitrosamine, concurrent with the appearance of precancerous hepatocytes. GD3 levels gradually increased to a peak of 4 times that of normal rat liver at 20 wk. CMP-NeuAc:GM3 sialyltransferase, the enzyme that synthesizes GD3 by transfer of sialic acid to GM3, also had tumor-associated elevation during the course of diethylnitrosamine-induction of rat hepatomas. To investigate the relationship of oncogene transformation and changes in ganglioside biosynthesis, NIH 3T3 cells transfected DNAs from human hepatoma or nasopharyngeal carcinoma were studied. The transfectants each expressed the same ganglioside composition, including a detectable level of GD3, as well as enhanced activity of CMP-NeuAc:GM3 sialyltransferase. A correlation between the tumor DNA transfection and the augmentation of GD3 in malignant cells is discussed. Because of the early appearance of GD3 in hepatoma and its possible relationship to oncogene activation, GD3 may be a potentially useful early tumor marker.

Abstract
Tu-er-feng is one of famous Chinese folk medicines in Sichuan prov. for common cold with cough, rheumatism, etc. Its sources are said to be either whole plants of some Gerbera or Ainsliaea species of family Compositae. In the recent markets, two types of Tu-er-feng are surely available. In this paper, Tu-er-feng derived from Gerbera species are studied to clarify the botanical origin; comparing mainly with the internal morphologies of the leaves and roots of G. piloselloides, G. delavayi, G. nivea, G. anandria (= Leibnitzia anandria) and G. jamesonii. As the result, G. piloselloides is determined as the botanical origin of Tu-er-feng obtained from the recent 16 markets.

Abstract
In the previous paper, Tu-er-feng, one of Chinese folk medicines used locally in Sichuan prov., derived from the whole plants of Gerbera piloselloides of family Compositae, was pharmacognostically reported. In the recent markets, besides this known material, Tu-er-feng made of different components are found. In this paper, the Ainsliaea derivatives are studied to clarify the botanical origins; comparing anatomically with leaves and petioles of thirteen Ainsliaea species growing wildly in Sichuan prov. The result shows that A. glabra and A. rubrinervis are the ingredients.
