Abstract
Adult-onset immunodeficiency syndrome due to anti-interferon (IFN)-γ autoantibodies has attracted much attention in recent years. It usually occurs in previously healthy people and usually presents as chronic, recurrent, and hard-to-control infections that can be effectively treated with aggressive antibiotic therapy. Adult-onset immunodeficiency syndrome is also referred to as AIDS-like syndrome. Anti-type I IFN (IFN-I) autoantibodies have been reported to play a significant role in the pathogenesis of coronavirus disease 2019 (COVID-19) and preexisting anti-IFN-I autoantibodies are associated with an increased risk of severe COVID-19. This review summarizes the effects of anti-IFN autoantibodies on the susceptibility and severity of various infectious diseases, including SARS-CoV-2 infection. In addition, we discuss the role of anti-IFN autoantibodies in the pathogenesis of autoimmune diseases that are characterized by recurrent infections.

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
From November to December of 2018, twenty 65-year-old or older women patients with knee osteoarthritis were recruited from the Department of Physical Therapy, the First Affiliated Hospital of Anhui Medical University. Meanwhile, twenty healthy 65-year-old or older women were recruited from the local community. The results showed that the knee contact angle of the patient group was more flexed (P=0.040), and the minimum angle of the knee joint increased (P=0.008) during the stance period compared to the healthy group. However, there was no significant difference in the maximum contact angle between the angle of hip and ankle joints. In addition, the tibialis anterior muscle of the patients was significantly smaller than the healthy group (P=0.023). Therefore, knee osteoarthritis could change the gait and muscle activity of older women, especially the knee joint.

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
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
To avoid serious damage in the pulse forming line (PFL) caused by repeated breakdown, a simple feedback control method based on a reverse peak voltage of the primary capacitor of the transformer is presented in this paper. The theoretical analysis of the breakdown circuit is carried out. The results indicate that once the breakdown occurs, the reverse peak voltage of the primary capacitor of the transformer increases obviously. A simple comparison function is added in the control system of the accelerator. If the collected reverse peak voltage of the primary capacitor is higher than the reference value, then the accelerator stops working immediately. The experimental result shows that this method can prevent the re-breakdown of the PFL effectively.

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 carbides in ultrahigh strength round steel have been investigated by using laser-assisted atom probe tomography (APT) and high resolution transmission electron microscopy (HRTEM) in this paper. Two kinds of carbides are found and one is iron carbide M6C, where carbide formation elements Cr, Mn and Mo replace partial Fe, while the other is niobium carbide MC, where M includes V and Mo besides Nb. These two carbides, due to their different evaporation field, have various densities in reconstructed image of APT. After correction, the hydrogen content within these two carbides illustrates that M6C cannot trap hydrogen, while MC can. The different behaviors in trapping hydrogen between these two carbides may result from elements Fe or Cr in M6C carbide having weaker affinity for hydrogen than Nb and V have in MC.

Abstract
Objective: To study the clinicopathologic features of thyroid-like follicular renal cell carcinoma. Methods: Clinical data were collected in 5 cases of thyroid-like follicular renal cell carcinoma. HE staining and immunohistochemistry were carried out in surgically-removed specimen to analyze the clinical and pathological features with review of the literatures. Results: The patients aged 20-55 years, with one male and four females; the tumor occurred in the left kidney in three cases and right kidney in two cases. One case had a history of thyroid papillary carcinoma 3 years ago, and the patient had left flank pain, macroscopic haematuria for 2 weeks. The rest four cases had no consciousness of clinical symptoms and signs, without history of thyroid gland surgery; the physical examination found a mass in the kidney and normal thyroid glands. Three patients underwent radical nephrectomy, and the other two patients underwent tumor partial nephrectomy. The tumors were 2-4 cm in size. They showed a solitary nodular mass of well circumscribed with taupe and gray on cut surface. Microscopically, most of tumor cells arranged in thyroid follicular pattern in different sizes, with papillary configuration in a small portion, in four cases; the follicular structure was intermixed with the papillary each half in one case. A large amount of thyroid colloid was deposited within follicule-like structure or papillary axis, lined by simple columnar cells or cubic cells, with obvious atypia, ground-glass nuclei, nuclear groove and rare mitosis. Immunohistochemical staining showed tumor cells were positive for PAX8, and negative for thyroid transcription factor 1 (TTF1) and thyroglobulin (Tg). One of five patients presented with lymph node metastases (4/4) of renal hilum the same time in the diagnosis. Five cases were followed up for 5-84 months after operation, and no tumor progression was found. Conclusions: Thyroid-like follicular renal cell carcinoma is primary renal epithelial malignant tumor. The diagnosis mainly depends on its characteristics of histological appearance, namely similar to the histological morphology of well-differentiated thyroid follicular carcinoma and papillary carcinoma, and the metastasis from the thyroid papillary or follicular carcinoma must be excluded. On the premise of clinical history, immunohistochemical markers TTF1 and Tg have certain value in the differential diagnosis.

Abstract
SHARP1 is a basic helix‑loop‑helix transcription factor involved in various cellular processes, including proliferation and differentiation. The present study assessed the role of SHARP1 in the progression and invasion of thyroid cancer. PCR and western blot analysis demonstrated that in thyroid cancer tissues, SHARP1 was significantly downregulated at the mRNA and protein level compared with that in normal tissues. Furthermore, SHARP1 was downregulated in the TT and TPC‑1 thyroid cancer cell lines compared with a normal thyroid cell line, while it was upregulated in other thyroid cancer cell lines. Overexpression of SHARP1 in TT and TPC‑1 cells significantly inhibited the cell viability, migration and invasion in vitro. Furthermore, the protein and mRNA levels of HIF‑1α were found to be decreased in TT and TPC‑1 cells following forced overexpression of SHARP1. In addition, silencing of HIF‑1α reduced the viability, migration and invasion of TT and TPC-1 cells. In conclusion, the present study indicated that SHARP1 acts as a tumor suppressor in thyroid cancer and that its downregulation may contribute to the proliferation, migration and invasion of thyroid cancer cells through mechanisms possibly involving HIF‑1α, suggesting that SHARP1 may be an important therapeutic target for the treatment of thyroid cancer.

Abstract
The nitric oxide (NO) formation and intrinsic nitrosation may be involved in the possible mechanisms of liver fluke-associated carcinogenesis. We still do not know much about the responses of inducible NO synthase (iNOS) induced by Clonorchis sinensis infection. This study was conducted to explore the pathological lesions and iNOS expressions in the liver of mice with different infection intensity levels of C. sinensis. Extensive periductal inflammatory cell infiltration, bile duct hyperplasia, and fibrosis were commonly observed during the infection. The different pathological responses in liver tissues strongly correlated with the infection intensity of C. sinensis. Massive acute spotty necrosis occurred in the liver parenchyma after a severe infection. The iNOS activity in liver tissues increased, and iNOS-expressing cells with morphological differences were observed after a moderate or severe infection. The iNOS-expressing cells in liver tissues had multiple origins.

Abstract
Alzheimer's disease (AD) is associated with the inflammatory response in response to amyloid β-peptide (Aβ). Previous studies have suggested that paeoniflorin (PF) shows anti-inflammatory and neuroprotective effects in inflammation-related diseases. However, the impacts of PF on AD have not been investigated. In the present study, we showed that a 4-week treatment with PF could significantly inhibit Aβ burden, Aβ-induced over activation of astrocytes and microglia, downregulation of proinflammatory cytokines, and upregulation of anti-inflammatory cytokines in the brain. In addition, we demonstrated that chronic treatment with PF inhibited the activation of glycogen synthase kinase 3β (GSK-3β) and reversed neuroinflammtory-induced activation of nuclear factor-kappa B (NF-κB) signaling pathways. Moreover, PF exerted inhibitory effects on NALP3 inflammasome, caspase-1, and IL-1β. Collectively, in the present study, we demonstrated that PF exhibits neuroprotective effects in amyloid precursor protein (APP) and presenilin 1 (PS1) double-transgenic (APP/PS1) mice via inhibiting neuroinflammation mediated by the GSK-3β and NF-κB signaling pathways and nucleotide-binding domain-like receptor protein 3 inflammasome. Thus, these results suggest that PF might be useful to intervene in development or progression of neurodegeneration in AD through its anti-inflammatory and anti-amyloidogenic effects.

Abstract
Clonorchis sinensis is a food-borne parasite that induces a permanent increase of nitrosation in the body upon infection. The spleen is an important secondary lymphoid organ for the regulation of immune responses locally and in the whole body. However, the functions and mechanisms of the spleen in nitric oxide (NO) responses after C. sinensis infection remain unknown. In this study, BALB/c mice were infected with 20, 40, and 80 C. sinensis metacercariae to simulate mild, moderate, and severe infections, respectively. We examined the expression of inducible nitric oxide synthase (iNOS) in the spleen and the relevant cytokine transcription in splenocytes from the mice infected with different amounts of metacercariae. The iNOS of the mice infected with 80 metacercariae was expressed in the spleen as early as 10 days post-infection (dpi) and gradually increased until 90 dpi. The iNOS expression in the mice infected with 40 metacercariae was detected only at 45 and 90 dpi, but not in the mice infected with 20 metacercariae. The level of interferon (IFN)-γ messenger RNA (mRNA) transcription in splenocytes significantly increased at 10 and 20 dpi (P < 0.05) in response to mild/moderate infection but gradually decreased to normal levels after 45 dpi. The level of IL-12p35 mRNA transcription did not change at 10 and 20 dpi but significantly decreased after 45 dpi under moderate/severe infection (P < 0.05/0.01/0.001). The level of IL-18 mRNA transcription significantly increased at 10 dpi (P < 0.05/0.01) but significantly decreased after 20 dpi (P < 0.05/0.01/0.001). These results suggest that spleen is an important organ for iNOS/NO responses, which correspond to the severity of C. sinensis infection, but cannot be attributed to the expression of the Th1 cytokines.

Abstract
Adipokines produced from adipose tissues participate in regulation of reproduction, energy homeostasis, food intake, and neuroendocrine function in the hypothalamus. We have previously reported that adiponectin significantly reduced GnRH secretion from GT1-7 hypothalamic GnRH neuron cells. In this study, we further investigated the inhibition of GnRH secretion by adiponectin in vivo and found that extracellular signal-regulated kinase (ERK) was inhibited and AMPK activated. Furthermore, we found that activated AMPK by adiponectin reduced ERK phosphorylation, which possibly impaired GnRH secretion in GT1-7 cells.

Abstract
The long period of bony consolidation is a concern in mandibular distraction osteogenesis (DO). We have previously shown that repeated local injections of human nerve growth factor beta (NGFβ) can appreciably improve bony consolidation in a rabbit model of DO. The present study was designed to test the effect of a single injection of human NGFβ delivered by collagen/nano-hydroxyapatite/kappa-carrageenan gels to sites of new bony formation in DO. Rabbits underwent mandibular DO at a rate of 0.75 mm/12h for 6 days. At the end of the distraction period, the following injections were given percutaneously into the callus (n=6 in each of the four groups): human NGFβ in the gel; human NGFβ in saline; the gels alone; and saline alone. Fourteen days after the end of distraction, mechanical testing, histological and histomorphometric variables of the new bone were evaluated. Histologically, the NGFβ group had more advanced consolidation than the other three groups. Both maximal load and bone volume/total volume in this group were significantly higher than in the other three (P<0.05). In conclusion, the delivery of human NGFβ in the gels results in better acceleration of new bone formation than when it is given in saline, and may be a possible way to shorten the duration of craniofacial DO.

Abstract
Reproduction is accurately regulated by metabolic states in mammals. Adiponectin regulates luteinizing hormone (LH) secretion in the pituitary and energy homeostasis in the hypothalamus. We further investigated the gonadotropin-releasing hormone (GnRH) secretion regulation by adiponectin and its related molecular and electrophysiological mechanisms. The results showed that adiponectin receptors (AdipR1 and 2) were expressed in GT1-7 cells derived from hypothalamus neurons. GnRH secretion was inhibited via activation of AMP-activated protein kinase (AMPK). Moreover, we revealed that hyperpolarization of plasma membrane potentials and reduction of calcium influx was also caused by adiponectin.
