Abstract
BACKGROUND Lupus erythematosus (LE) is a spectrum of autoimmune diseases. Due to the complexity of cutaneous LE (CLE), clinical skin image-based artificial intelligence is still experiencing difficulties in distinguishing subtypes of LE. OBJECTIVES We aim to develop a multimodal deep learning system (MMDLS) for human-AI collaboration in diagnosis of LE subtypes. METHODS This is a multi-centre study based on 25 institutions across China to assist in diagnosis of LE subtypes, other eight similar skin diseases and healthy subjects. In total, 446 cases with 800 clinical skin images, 3786 multicolor-immunohistochemistry (multi-IHC) images and clinical data were collected, and EfficientNet-B3 and ResNet-18 were utilized in this study. RESULTS In the multi-classification task, the overall performance of MMDLS on 13 skin conditions is much higher than single or dual modals (Sen = 0.8288, Spe = 0.9852, Pre = 0.8518, AUC = 0.9844). Further, the MMDLS-based diagnostic-support help improves the accuracy of dermatologists from 66.88% ± 6.94% to 81.25% ± 4.23% (p = 0.0004). CONCLUSIONS These results highlight the benefit of human-MMDLS collaborated framework in telemedicine by assisting dermatologists and rheumatologists in the differential diagnosis of LE subtypes and similar skin diseases.

Abstract
Background Pyoderma gangrenosum (PG) is a rare cause of skin ulcers in children, posing challenges in diagnosis and treatment. As the disease is often associated with conditions such as inflammatory bowel disease (IBD), rheumatoid arthritis, haematological disorders and other diseases, diagnosis and treatment often require cooperation with other medical departments. Accordingly, dissemination of information about the disease to doctors in departments other than dermatologists, especially paediatricians, can help in its early detection. Case Presentation The 11-year-old pediatric patient in the case initially diagnosed with acute febrile neutrophilic dermatosis was eventually confirmed as pustular PG through histopathological examinations of skin and other relevant examinations. The medical condition is lessened after treatment with a combination of glucocorticoids and adalimumab. Conclusion PG is relatively rare in clinical settings, particularly among pediatric patients exhibiting persistent high fever and signs of pustular pyoderma gangrenosum. This case underscores the importance of considering the potential diagnosis of pediatric pustular PG when confronted with a child presenting persistent high fever and pustules after trauma. Additionally, the proactive initiation of adalimumab emerges as a promising treatment option for pediatric IBD -associated pustular PG.

Abstract
Systemic Lupus Erythematosus (SLE) is an autoimmune sickness with unclear pathogenesis. The goal of this research was to reveal the heterogeneity of immune cells in SLE patients of Han and Zang nationality by single-cell RNA sequencing (scRNA-seq) and bioinformatics profiling. METHODS A total of 94,102 peripheral blood mononuclear cells (PBMCs) from six volunteers with SLE (3 Zang, 3 Han) and six healthy controls were first conducted through scRNA-seq analysis. The immune cell subsets in the pathogenesis of SLE were analyzed as well. Real-time quantitative PCR (RT-qPCR) was applied to confirm the results of sc-RNA seq analysis. RESULTS For the Tibetan samples, the ratios of Naïve CD4 RPS4Y1 cells, Naïve CD4 cells, Memory BC CD24 and Memory BC differed significantly between the SLE and control samples, while that of CD8 CTL MAL cells was significantly different between the two groups in Han nationality samples. Variable differentiation states of CD8 CTL MAL cells, CD8 CTL GZMK cells, and Naïve CD4 cells were detected through pseudotime analysis. Moreover, T-cell receptor (TCR) abundance was notably higher in Tibetan SLE specimens than that in controls, while B-cell receptor (BCR) abundance in Tibetan and Han samples was higher than in control groups. CONCLUSIONS In summary, the immune cellular heterogeneity of SLE patients both Han and Zang nationality was explored based on various bioinformatics approaches, providing new perspectives for immunological characteristics of SLE among different ethnic groups.

Abstract
BACKGROUND There are no standards for evaluating skin photoaging. Dermoscopy is a non-invasive detection method that might be useful for evaluating photoaging. OBJECTIVE To assess the correlation between the dermoscopic evaluation of photoaging and clinical and pathological evaluations. METHODS The age, clinical evaluation (Fitzpatrick classification, Glogau Photoaging Classification, and Chung's standardized image ruler), histopathology (Masson staining and MMP-1 immunohistochemistry), and dermoscopy (Hu's and Isik's) of 40 donor skin samples were analyzed statistically, and Spearman rank correlation analysis was performed. RESULTS There was a robust correlation between the total Hu scores and Isik dermoscopy. The correlation of dermoscopy with histopathology was higher than that of clinical evaluation methods. There is a strong correlation between telangiectases and lentigo. Xerosis, superficial wrinkle, diffuse erythema, telangiectases, and reticular pigmentation were significantly correlated with the three clinical evaluation methods. Superficial wrinkles were correlated with Masson, MMP-1, various clinical indicators, and other dermoscopic items. CONCLUSION There is a good correlation between dermoscopy and clinical and histopathological examination. Dermoscopy might help evaluate skin photoaging.

Abstract
Photoaging is unique to the skin and is accompanied by an increased risk of tumors. To explore the transcriptomic regulatory mechanism of skin photoaging, the epidermis, and dermis of 16 healthy donors (eight exposed and eight non-exposed) were surgically excised and detected using total RNA-Seq. Weighted gene co-expression network analysis (WGCNA) identified the most relevant modules with exposure. The hub genes were identified using correlation, p-value, and enrichment analysis. The critical genes were identified using Support Vector Machine-Recursive Feature Elimination (SVM-RFE) and least absolute shrinkage and selection operator (LASSO) regression, then enriched using single-gene GSEA. A competitive endogenous RNA (ceRNA) network was constructed and validated using qRT-PCR. Compared with non-exposed sites, 430 mRNAs, 168 lncRNAs, and 136 miRNAs were differentially expressed in the exposed skin. WGCNA identified the module MEthistle and 12 intersecting genes from the 71 genes in this module. The enriched pathways were related to muscle. The critical genes were KLHL41, MYBPC2, and ERAP2. Single-gene GSEA identified the Hippo signaling pathway, basal cell carcinoma, cell adhesion molecules, and other pathways. Six miRNAs and 18 lncRNAs related to the critical genes constituted the ceRNA network and were verified using qPCR. The differential expression of KLHL41, MYBPC2, and ERAP2 at the protein level was verified using immunohistochemistry. KLHL41, MYBPC2, and ERAP2 genes are related to skin photoaging. The prediction model based on the three critical genes can indicate photoaging. These critical genes may have a role in skin photoaging by regulating cell growth, intercellular adhesion, and substance metabolism pathways.

Abstract
1. Although PRL-PRLR signalling plays important roles in regulating avian reproduction, there is a paucity of information regarding the functional significance of PRLR in goose ovarian follicle development.2. The full-length 2,496 bp coding sequence of PRLR was obtained from Sichuan White goose (Anser cygnoides) for the first time and was seen to encode a polypeptide containing 831 amino acids. Goose PRLR shares similar sequence characteristics and conserved functional domains to other avian species and was phylogenetically clustered into the avian clade.3. The qPCR results suggested that the mRNA levels of PRLR significantly increased in primary follicles during weeks 3 to 4 of age and were higher in secondary- than in primordial follicles at week 5 post-hatching, which suggested that the PRLR-mediated signalling could be involved in regulation of early folliculogenesis.4. The PRLR mRNA was expressed at the highest levels in the prehierarchical 8-10 mm granulosa layers throughout goose ovarian follicle development, indicating a role for PRLR in the process of follicle selection.5. PRLR mRNA was differentially expressed in the three cohorts of in vitro cultured granulosa cells harvested from different sized goose ovarian follicles, which suggested that PRLR was involved in regulating granulosa cell functions depending on the stage of follicle development. These data provide novel insights into the role of PRLR during goose ovarian follicle development, although the underlying mechanisms await further investigations.

Abstract
INTRODUCTION This phase III study aimed to compare the efficacy, safety, and immunogenicity of SCT630 with the reference adalimumab. METHODS A total of 367 Chinese patients with moderate-to-severe plaque psoriasis were randomly assigned to receive 80 mg of SCT630 or adalimumab subcutaneously at week 1, 40 mg at week 2, then 40 mg biweekly. At week 16, those with 50 % or more improvement in psoriasis area and severity index (PASI) were eligible to enter an extension period up to week 52. Patients on SCT630 continued the same treatment, whereas patients receiving adalimumab were re-randomized at a ratio of 1:1 to adalimumab or SCT630 group. The primary endpoint was percentage improvement in PASI at week 16. Other endpoints included PASI 50/75/90/100, Physician's Global Assessment, Dermatology Life Quality Index, safety, and immunogenicity. RESULTS PASI improvement at week 16 was 85.07 % for SCT630 and 84.82 % for adalimumab. The mean difference (3.10 %, 95 % CI: -1.875 %, 8.066 %) was within the equivalence interval. Other efficacy endpoints, safety and immunogenicity profiles were similar across the two groups. There were no safety or immunogenicity difference between switched/continued groups. CONCLUSION This phase III study demonstrated the equivalences in efficacy, safety and immunogenicity of SCT630 to adalimumab in patients with moderate to severe psoriasis.

Abstract
The lunar nearside has been investigated by many uncrewed and crewed missions, but the farside of the Moon remains poorly known. Lunar farside exploration is challenging because maneuvering rovers with efficient locomotion in harsh extraterrestrial environment is necessary to explore geological characteristics of scientific interest. Chang'E-4 mission successfully targeted the Moon's farside and deployed a teleoperated rover (Yutu-2) to explore inside the Von Kármán crater, conveying rich information regarding regolith, craters, and rocks. Here, we report mobile exploration on the lunar farside with Yutu-2 over the initial 2 years. During its journey, Yutu-2 has experienced varying degrees of mild slip and skid, indicating that the terrain is relatively flat at large scales but scattered with local gentle slopes. Cloddy soil sticking on its wheels implies a greater cohesion of the lunar soil than encountered at other lunar landing sites. Further identification results indicate that the regolith resembles dry sand and sandy loam on Earth in bearing properties, demonstrating greater bearing strength than that identified during the Apollo missions. In sharp contrast to the sparsity of rocks along the traverse route, small fresh craters with unilateral moldable ejecta are abundant, and some of them contain high-reflectance materials at the bottom, suggestive of secondary impact events. These findings hint at notable differences in the surface geology between the lunar farside and nearside. Experience gained with Yutu-2 improves the understanding of the farside of the Moon, which, in return, may lead to locomotion with improved efficiency and larger range.

Abstract
INTRODUCTION Adalimumab has been used successfully in the treatment of psoriasis. The objective of the study is to compare the efficacy, safety, and immunogenicity between HLX03, an adalimumab biosimilar, and adalimumab in Chinese patients with moderate-to-severe plaque psoriasis. METHODS In this double-blind, active-controlled, parallel-group study, 262 patients with moderate-to-severe plaque psoriasis were randomized (1:1) to receive HLX03 or adalimumab (80 mg at week 1, 40 mg at week 2, and then 40 mg every 2 weeks) for 48 weeks. The primary endpoint was improvement in Psoriasis Area and Severity Index (PASI) score at week 16 comparing to baseline. Equivalence was demonstrated if 95% confidence interval (CI) of the between group difference fell within the equivalence margins of ± 15%. Other efficacy endpoints, safety and immunogenicity were also evaluated. RESULTS In the full analysis set, PASI improvements at week 16 was 83.5% (n = 131) in the HLX03 group and 82.0% (n = 130) in the adalimumab group, with a least-square-mean difference of 1.5% (95% CI - 3.9% to 6.8%). There were no significant between-group differences in all secondary efficacy analyses including proportion of patients achieving ≥ 75% improvement from baseline PASI (PASI 75), physician global assessment (PGA) 0/1 (clear or almost clear) and change in dermatology life quality index (DLQI) score. The incidences of adverse events and the proportion of patients with antidrug antibodies were also comparable between the two treatment groups. CONCLUSION HLX03 demonstrated equivalent efficacy, similar safety and immunogenicity to reference adalimumab, supporting its development as an alternative treatment for patients with plaque psoriasis in China.

Abstract
Objective Systemic lupus erythematosus (SLE) is an autoimmune disease with complex etiology that is not yet entirely understood. We aimed to elucidate the mechanisms and therapeutic potential of microRNAs (miRNAs) in SLE in a Tibetan population. Methods Peripheral blood mononuclear cells from SLE patients (n = 5) and healthy controls (n = 5) were used for miRNA–mRNA co-sequencing to detect miRNAs related to immune abnormalities associated with SLE. Luciferase reporter assay was used to identify potential targets of candidate miRNA. The target genes were verified in miRNA-agomir/antagomir transfection assays with multiple cells lines and by expression analysis. The effects of candidate miRNA on monocyte and macrophage activation were evaluated by multiple cytokine profiling. Neutrophil extracellular traps (NETs) formation was analyzed in vitro by cell stimulation with supernatants of monocytes and macrophages transfected with candidate miRNA. The rodent MRL/lpr lupus model was used to evaluate the therapeutic effect of CXCL2Ab on SLE and the regulation effect of immune disorders. Results Integrated miRNA and mRNA expression profiling identified miRNA-4512 as a candidate miRNA involved in the regulation of neutrophil activation and chemokine-related pathways. MiR-4512 expression was significantly reduced in monocytes and macrophages from SLE patients. MiR-4512 suppressed the TLR4 pathway by targeting TLR4 and CXCL2. Decreased monocyte and macrophage miR-4512 levels led to the expression of multiple proinflammatory cytokines in vitro. Supernatants of miR-4512 antagomir-transfected monocytes and macrophages significantly promoted NETs formation (P < 0.05). Blocking of CXCL2 alleviated various pathogenic manifestations in MRL/lpr mice, including kidney damage and expression of immunological markers of SLE. Conclusions We here demonstrated the role of miR-4512 in innate immunity regulation in SLE. The effect of miR-4512 involves the regulation of monocytes, macrophages, and NETs formation by direct targeting of TLR4 and CXCL2, indicating the miR-4512-TLR4-CXCL2 axis as a potential novel therapeutic target in SLE.

Abstract
Excessive activation of immune cells plays a key role in the pathogenesis of systemic lupus erythematosus (SLE). The regulation of immune cells by miRNAs is a research hotspot. In this study, second-generation high-throughput sequencing revealed a reduction in miR-99a-3p expression in patients with SLE; however, the specific mechanism underlying this phenomenon remains unclear. After transfection with an miR-99a-3p agomir, the proliferation of Ball-1 cells decreased and the levels of their apoptosis increased. The opposite effects were observed in cells transfected with the miR-99a-3p antagomir. Luciferase reporter assay indicated that miR-99a-3p directly targeted EIF4EBP1. Rescue experiments confirmed the proposed interaction between miR-99a-3p and EIF4EBP1. In vitro, in vivo and clinical investigations further confirmed that the miR-99a-3p agomir reduced the expression of EIF4EBP1, LC3B and LAMP-2A. In the in vivo experiments, serum levels of anti-nuclear antibodies, double-stranded DNA, IgE, IgM, IL-6, IL-10 and B lymphocyte stimulator were higher in mice from the antagomir group than those in mice from the MRL/lpr group. Furthermore, the protein and mRNA levels of EIF4EBP1, LC3B and LAMP-2A, the intensity of immunohistochemical staining of EIF4EBP1, LC3B and LAMP-2A, the urinary protein levels, and the C3 immunofluorescence deposition increased in mice from the antagomir group. The upregulation of miR-99a-3p expression protected B cells from EIF4EBP1-mediated autophagy, whilst the downregulation of miR-99a-3p expression induced autophagy via the EIF4EBP1-mediated regulation of the autophagy signalling pathway in B cells isolated from individuals with SLE. Based on these results, miR-99a-3p and EIF4EBP1 may be considered potential targets for SLE treatment.

Abstract
Cutaneous lupus erythematosus (CLE) is an inflammatory, autoimmune disease encompassing a broad spectrum of subtypes including acute, subacute, chronic and intermittent CLE. Among these, chronic CLE can be further classified into several subclasses of lupus erythematosus (LE) such as discoid LE, verrucous LE, LE profundus, chilblain LE and Blaschko linear LE. To provide all dermatologists and rheumatologists with a practical guideline for the diagnosis, treatment and long-term management of CLE, this evidence- and consensus-based guideline was developed following the checklist established by the international Reporting Items for Practice Guidelines in Healthcare (RIGHT) Working Group and was registered at the International Practice Guideline Registry Platform. With the joint efforts of the Asian Dermatological Association (ADA), the Asian Academy of Dermatology and Venereology (AADV) and the Lupus Erythematosus Research Center of Chinese Society of Dermatology (CSD), a total of 25 dermatologists, 7 rheumatologists, one research scientist on lupus and 2 methodologists, from 16 countries/regions in Asia, America and Europe, participated in the development of this guideline. All recommendations were agreed on by at least 80% of the 32 voting physicians. As a consensus, diagnosis of CLE is mainly based on the evaluation of clinical and histopathological manifestations, with an exclusion of SLE by assessment of systemic involvement. For localized CLE lesions, topical corticosteroids and topical calcineurin inhibitors are first-line treatment. For widespread or severe CLE lesions and (or) cases resistant to topical treatment, systemic treatment including antimalarials and (or) short-term corticosteroids can be added. Notably, antimalarials are the first-line systemic treatment for all types of CLE, and can also be used in pregnant patients and pediatric patients. Second-line choices include thalidomide, retinoids, dapsone and MTX, whereas MMF is third-line treatment. Finally, pulsed-dye laser or surgery can be added as fourth-line treatment for localized, refractory lesions of CCLE in cosmetically unacceptable areas, whereas belimumab may be used as fourth-line treatment for widespread CLE lesions in patients with active SLE, or recurrence of ACLE during tapering of corticosteroids. As for management of the disease, patient education and a long-term follow-up are necessary. Disease activity, damage of skin and other organs, quality of life, comorbidities and possible adverse events are suggested to be assessed in every follow-up visit, when appropriate.

Abstract
Acne is associated with depression and anxiety; however, the relationship between acne and suicide is still unclear. This study is aimed to evaluate the association between acne and suicide by conducting a meta-analysis. Studies were identified by electronic searches of the PubMed and EMBASE databases from their inception through Jan 10, 2020. Two authors separately assessed the quality and extracted data from the selected studies. When the heterogeneity was significant, we used a random-effects model to calculate overall pooled risk estimates.Five studies involving a total of 2,276,798 participants were finally included in the meta-analysis; 52,075 participants had acne. Suicide was positively associated with acne in the overall analysis (odds ratio (OR) 1.50, 95% confidence interval (95% CI): 1.09-2.06, P = .004, I2 = 74.1%). Subgroup analyses were performed for suicidal behavior groups (P = .002, I2 = 80.4%), suicidal ideation or thoughts groups (P = .849, I2 = 0.0%), International Classification of Diseases version 9 (ICD-9) groups (P = .137, I2 = 49.6%), non-ICD-9 groups (P = .950, I2 = 0.0%), American groups (P = .311, I2 = 2.4%), and non-American groups (P = .943, I2 = 0.0%). Sensitivity analyses indicated flawed results. No publication bias was detected.Acne may significantly increase suicide risk. Clinicians should actively treat acne and consider suicide screening. Further international studies with high-quality analyses are needed as more data are published.Ethical approval and patient consent are not required because this study is a literature-based study.

Abstract
OBJECTIVE The purpose of this study was to investigate GOLPH3 expression in nasopharyngeal carcinoma (NPC) and its influence on the metastatic ability of NPC cells; meanwhile, the underlying mechanism of GOLPH3 promoting the malignant progression of NPC was also explored. PATIENTS AND METHODS In this study, quantitative Real Time-Polymerase Chain Reaction (qRT-PCR) was performed to examine the expression of GOLPH3 in 34 pairs of tumor tissue and paracancerous tissue specimens collected from NPC patients, and the interplay between GOLPH3 expression and clinical indicators was analyzed, as well as the prognosis of NPC patients. Meanwhile, GOLPH3 expression in NPC cell lines was further verified by qRT-PCR assay. Furthermore, GOLPH3 knockdown model was constructed in NPC cell lines, including SUNE2 and CNE. Then, cell counting kit-8 (CCK-8), transwell invasion, and cell wound healing assays were applied to analyze the effect of GOLPH3 on the biological function of NPC cells. In addition, an in-depth study of the relationship between GOLPH3 and E-cadherin was conducted. RESULTS QRT-PCR results indicated that the expression level of GOLPH3 in NPC was remarkably higher than that in adjacent tissues, and the difference was statistically significant. Compared with patients with low expression of GOLPH3, those with high expression of GOLPH3 had a higher incidence of lymph node metastasis. Compared with sh-NC group, the proliferation and invasive ability of NPC cells decreased remarkably after knockdown of GOLPH3. Subsequently, E-cadherin expression was found to be remarkably reduced and negatively correlated with GOLPH3 in NPC cell lines and tissues. Finally, the recovery experiment demonstrated that GOLPH3 might have a mutual regulatory relation with E-cadherin, both of which jointly affect the malignant progression of NPC. CONCLUSIONS GOLPH3 expression is remarkably associated with lymph node metastasis and poor prognosis of NPC patients; in addition, it may promote the proliferation and metastatic ability of NPC cells by regulating E-cadherin.

Abstract
Previous evidences have indicated that granulosa cells play a critical role in follicular growth. Hydrogen peroxide (H2O2)-induced oxidative stress has been associated with ovarian granulosa cell apoptosis and ovarian function. Recently, a study highlighted the protective role of morroniside against H2O2-induced damage. In this study, we aimed to investigate the effects of morroniside on H2O2-stimulated rat ovarian granulosa cells and its underlying molecular mechanisms. Our results showed that H2O2 treatment suppressed cell survival and increased apoptosis in rat granulosa cells, while treatment with morroniside markedly increased H2O2-induced granulosa cell survival in a dose-dependent manner (0, 10, 50 and 100 µM). Moreover, treatment with 50 µM morroniside impeded H2O2-induced cell apoptosis. An elevation in intracellular ROS, MDA, SOD, GSH-Px, and CAT level was observed in H2O2-induced granulosa cells; however, this effect was abrogated by morroniside treatment. Further studies suggested that administration of morroniside inhibited H2O2-induced granulosa cell apoptosis and caspase-3 activity. In addition, after morroniside treatment of H2O2-stimulated granulosa cells, autophagy-related protein (LC3-II/LC3-I ratio) and beclin-1 expression was decreased and p62 level was increased. Interestingly, we found that morroniside treatment activated the PI3K/AKT/mTOR pathway in H2O2-stimulated granulosa cells. Finally, we showed that treatment with PI3K and mTOR inhibitors reversed the protective effects of morroniside on H2O2-induced granulosa cells. Taken together, our data suggest that treatment with morroniside decreased apoptosis, autophagy, and oxidative stress in rat granulosa cells through the PI3K/AKT/mTOR pathway.

Abstract
Although the original purpose of the systemic lupus erythematosus (SLE) classification criteria was to distinguish SLE from other mimic diseases, and to facilitate sample selection in scientific research, they have become widely used as diagnostic criteria in clinical situations. It is not known yet if regarding classification criteria as diagnostic criteria, what problems might be encountered? This is the first study comparing the three sets of classification criteria for SLE, the 1997 American College of Rheumatology (ACR’97), 2012 Systemic Lupus International Collaborating Clinics (SLICC’12) and 2019 European League Against Rheumatism/American College of Rheumatology (EULAR/ACR’19), for their ability to distinguish patients with SLE from patients with pure mucocutaneous manifestations (isolated cutaneous lupus erythematosus without internal disease, i-CLE) in the lupus disease spectrum. 1,865 patients with SLE and 232 patients with i-CLE were recruited from a multicenter study. We found that, due to low specificity, none of the three criteria are adept at distinguishing patients with SLE from patients with i-CLE. SLICC’12 performed best among the original three criteria, but if a positive ANA was removed as an entry criterion, EULAR/ACR’19 would performed better. A review of previous studies that compared the three sets of criteria was presented in this work.

Abstract
OBJECTIVE To explore the repair of spinal cord injury (SCI) in rats by umbilical cord mesenchymal stem cells (UCMSCs) through the p38mitogen-activated protein kinase (MAPK) signaling pathway. MATERIALS AND METHODS A total of 45 healthy adult male Sprague-Dawley rats weighing 180-220 g and aged 6-8 weeks old were randomly divided into group A (SCI model + transplantation of UCMSCs, n=15), group B (sham operation), and group C (SCI model + injection of an equal dose of DMEM, n=15) using a random number table. The morphology of spinal cord tissues was observed via hematoxylin-eosin (HE) staining, and the protein expression of phosphorylated p38 (p-p38) in spinal cord tissues, the expression of glial fibrillary acidic protein (GFAP) in the injury region, and the spinal cord neuronal apoptosis were detected via Western blotting, immunofluorescence labeling and terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling (TUNEL) assay, respectively. RESULTS In group B, there was no significant damage to the structure of spinal cord tissues. In group C, the spinal cord tissues had a disordered structure and significant fragmentation, the damage to grey matter was the greatest. Also, almost all of the grey matter was destroyed and dissolved, with a large number of scars and cavitation, and it was hard to distinguish the gray matter and white matter. In group A, the spinal cord tissues had a clear structure, there were smaller necrotic cavitation regions in the grey-white matter, and the number of cavitation significantly declined compared with that in group C. The results of immunofluorescence assay revealed that the expression of GFAP in spinal cord tissues was the lowest in group B, while it was remarkably decreased in group A compared with that in group C (p<0.05), suggesting that injecting UCMSCs via the caudal vein can prominently reduce the expression of GFAP in spinal cord tissues. Moreover, the spinal cord neuronal apoptosis rate was (4.21±0.19), (0.72±0.21) and (4.57±0.31), respectively, in group A, group B, and group C. It can be seen that the spinal cord neuronal apoptosis rate significantly declined in group A due to the treatment with UCMSCs. Also, the significant difference compared with that in group C, while it was significantly increased in group A compared with that in group B, but lower than group C (p<0.05). According to the results of Western blotting, the protein expression of p-p38 in spinal cord tissues was remarkably decreased in group B compared with that in group A and group C (p<0.05), while it was also markedly decreased in group A compared with that in group C (p<0.05), indicating that injecting UCMSCs via the caudal vein can significantly lower the protein expression of p-p38 in spinal cord tissues. CONCLUSIONS UCMSCs promote the recovery of neurological function, inhibit the p38 MAPK pathway activated after SCI, and reduce the spinal cord neuronal apoptosis in SCI rats.

Abstract
Background:Refractory gout manifests as recurrent flares, chronic arthritis and progressive tophaceous deposits. Febuxostat is a widely-used potent serum urate-lowering reagent, but some gout patients cannot achieve target serum uric acid (sUA) after they used this reagent.Objectives:To determine whether febuxostat-resistance should be a criterion for refractory gout, characteristics of gout patients who were resistance to febuxostat or allopurinol were compared.Methods:This study was performed from December 2015 to December 2019. Medical records of gout patients who met the 2015 gout classification criteria [1] and undertook febuxostat (febuxostat group) or allopurinol (allopurinol group) urate-lowing therapy (ULT) were assessed. Dose of ULT was adjusted till sUA was below 6 mg/dL and 5 mg/dL for patients with urate deposition. We screened gout patients who had contraindication or history of failure to normalize sUA for≥ 3 months of treatment with the maximum medically appropriate febuxostat (febuxostat-resistance) or allopurinol (allopurinol-resistance) dose as defined by physicians. Furthermore, these screened patients met the traditional criteria of refractory gout except therapeutic reaction [2].Demography and clinical characteristics were recorded. Features between febuxostat-resistance and allopurinol-resistance patients were compared.Results:(1) Of 683 gout patients who were included, 516 and 167 of them used febuxostat or allopurinol. (2) Age (41.92±11.58 vs. 42.26±9.41 years), Male gender (97.50% vs. 97.01%), duration of gout (5.78±4.74 vs. 5.05±4.72 years) and sUA (6.30±2.50 vs. 6.67±2.14 mg/dL) were similar between febuxostat group and allopurinol group (P>0.05). (3) Dose of febuxostat or allopurinol were 47.28mg/day and 178.24mg/day. (4) Sixteen patients were febuxostat-resistance, while 6 patients were allopurinol-resistance. Prevalence rates of treatment resistance were comparable between groups (3.10% vs. 3.59%,P>0.05). (5) Some parameters were different between resistance patients and non-resistance patients in both groups (Table 1,P<0.05). However, characteristics of febuxostat-resistance and allopurinol-resistance patients were similar (P>0.05).Table 1Characteristics of gout patients in febuxostat group and allopurinol groupParametersFebuxostat GroupAllopurinol GroupNon-resistance(n=500)Resistance(n=16)Non-resistance(n=161)Resistance(n=6)Age (year)41.93±11.6541.67±9.5842.22±13.3344.50±16.98Male Gender (%)97.40100.0096.89100.00BMI (kg/m2)25.44±3.4626.22±3.4725.86±3.9725.60±6.42Duration of gout (years)5.75±4.767.00±3.97*4.96±4.737.75±2.62*Flares in previous 18 months (times)1.31±0.443.67±0.70*1.13±0.243.25±0.50*Presence of Tophi (%)23.80100.00*14.90100.00*Presence of Complication (%)35.8100.00*31.06100.00*sUA (mg/dL)6.21±2.479.13±1.24*6.42±2.3210.15±3.55*SCr (μmol/L)100.67±15.03163.96±29.41*96.93±22.91133.75±31.60*ESR (mm/L)24.59±19.2842.83±21.13*27.49±24.1056.50±28.12*CRP (mg/L)18.92±18.5928.81±23.85*23.12±22.6332.28±23.64**P<0.05 compared with non-resistance patients in the same group.BMIbody mass index,sUAserum uric acid,SCrserum creatinine,ESRerythrocyte sedimentation rate,CRPC-reactive proteinConclusion:Febuxostat-resistance is a potential criterion for refractory gout, because febuxostat-resistance patients shares similar characteristics of patients with refractory gout.References:[1]Neogi T, Jansen TL, Dalbeth N, et al. 2015 Gout classification criteria: an American College of Rheumatology/European League Against Rheumatism collaborative initiative.

Abstract
Allergen-specific immunotherapy is widely used for allergic rhinitis and asthma treatment worldwide. This study explored the efficacy and safety of sublingual immunotherapy (SLIT) with the extracts of Dermatophagoides Farinae (D. farinae Drops) on house dust mites (HDM)-induced atopic dermatitis (AD). 239 patients with HDM-induced AD were recruited and exposure to a multi-centre, randomized, double-blind, and placebo-controlled clinical trials for 36 weeks, which were randomly divided into placebo and sublingual D. farinae Drops groups (high-dose, medium-dose and low-dose), respectively. Statistical analysis was performed in three groups: Full Analysis Set, Per Protocol Set and Safety Set. 48 cases have withdrawn from the study before the end of study. As primary outcomes, significant decreases in scoring atopic dermatitis and total medication score were showed in medium-dose and high-dose D. farinae Drops groups. In the sixth visit, the skin lesion area showed a statistically significant difference between high-dose/medium-dose D. farinae Drops group and placebo group (p < .05). Most adverse events are slight, and no life-threatening adverse drug reaction happened. Our research demonstrates the beneficial effect of SLIT with high or medium dose D. farinae Drops on AD, and the treatment was well tolerated.

Abstract
OBJECTIVES The present study aimed to explore the effect of umbilical cord mesenchymal stem cells (UC-MSCs) on the modulation of T lymphocytes from system lupus erythematosus (SLE) patients and the possible mechanism. METHODS A total of 24 hospitalized SLE patients and 28 healthy individuals were enrolled. T lymphocytes were sorted using Miltenyi magnetic beads. After the addition of recombinant human interleukin (IL)-2 and CD3CD28 T-cell activator, cells were loaded onto six-well plates pre-inoculated or not with UC-MSCs for 1 week of culture. The supernatants were collected for testing inflammatory factors by enzyme-linked immunosorbent assay. Meanwhile, T lymphocytes were collected to assess the expression levels of genes, proteins in relation to SLE and miR-181a by polymerase chain reaction and Western blot. RESULTS Compared with T lymphocytes cultured alone, interferon-γ, IL-4, IL-6 and IL-10 levels were significantly decreased in T lymphocytes from SLE patients co-cultured with UC-MSCs. In addition, the gene and protein expression levels of TNF alpha, osteopontin and nuclear factor-kappa B in T lymphocytes were significantly decreased, while miR-181a expression was markedly elevated (p < 0.05 or 0.008). CONCLUSION UC-MSCs have showed certain immunomodulatory and inhibitory effects in vitro on T lymphocytes from SLE patients, which could potentially be a beneficial treatment of the disease. UC-MSCs may up-regulate miR-181a and down-regulate inflammation-related gene expression.

Abstract
Background: Total P16 methylation (P16M), including P16 hydroxymethylation (P16H) and true-P16M, correlates with malignant transformation of oral epithelial dysplasia (OED). Both true-P16M and P16H are early events in carcinogenesis. Aim: The aim of this study is to prospectively determine if discrimination of true-P16M from P16H similarly is necessary for prediction of cancer development from OEDs. Methods: Patients (n = 265) with mild or moderate OED were recruited into the double-blind 2-center cohort. Total-P16M and P16H were analyzed using the 115-bp MethyLight, TET-assistant bisulfite (TAB) methylation-specific PCR (MSP), and TAB-sequencing. Total-P16M-positive and P16H-negative samples were defined as true-P16M-positive. Progression of OEDs was monitored for a minimum 24 months follow-up period. Results: P16H was detected in 23 of 73 (31.5%) total-P16M-positive OEDs. Follow-up information was obtained from 247 patients with an ultimate compliance of 93.2%. OED-derived squamous cell carcinomas were observed in 13.0% (32/247) patients during the follow-up (median, 41.0 months). The cancer progression rate for total-P16M-positive patients was significantly increased when compared with total-P16M-negative patients (23.3% vs 8.6%; adjusted odds ratio = 2.67 [95% CI: 1.19-5.99]). However, the cancer progression rate was similar between P16H- and true-P16M-positive OEDs (26.1% [6/23] vs 22.0% [11/50]; odds ratio = 0.80 [95% CI: 0.22-2.92]). The progression-free survival was also similar for these patients. Conclusion: P16H and true-P16M are similar biomarkers for determining malignant potential of OEDs. Discrimination of P16H from true-P16M, at least in OED, may be not necessary in clinical applications.

Abstract
To determine clinical curative effects of ozone therapy for pemphigus vulgaris.
Methods: Ozone hydrotherapy was used as an aid treatment for 32 patients with pemphigus vulgaris. The hydropathic compression of potassium permanganate solution for 34 patients with pemphigus vulgaris served as a control. The main treatment for both groups were glucocorticoids and immune inhibitors. The lesions of patients, bacterial infection, usage of antibiotics, patient's satisfaction, and clinical curative effect were evaluated in the 2 groups.
Results: There was no significant difference in the curative effect and the average length of staying at hospital between the 2 groups (P>0.05). But rate for the usage of antibiotics was significantly reduced in the group of ozone hydrotherapy (P=0.039). The patients were more satisfied in using ozone hydrotherapy than the potassium permanganate solution after 7-day therapy (P>0.05).
Conclusion: Ozone hydrotherapy is a safe and effective aid method for pemphigus vulgaris. It can reduce the usage of antibiotics.

Abstract
Diabetes mellitus II (DM II) is a newly defined independent factor contributing to the morbidity and mortality of cryptococcosis. This retrospective case analysis aims to explore the epidemiology, clinical profile and strain characteristics of cryptococcosis in Chinese DM II patients. This study included 30 cases of cryptococcosis with DM II occurring from 1993 to 2015 in mainland China. The hospital-based prevalence of cryptococcosis in DM II was 0.21%. The mean age of the patients was 56.1 years (95% confidence interval: 51.5, 60.6), and 93% of the patients were older than 40 years. Sixty-two per cent of the patients experienced untreated or poorly controlled blood glucose before infection. Multilocus sequence typing analysis categorised all cultured strains as Cryptococcus neoformans and sequence type 5. Sixty-nine per cent of pulmonary cryptococcosis patients experienced misdiagnoses and treatment delays. Sixty per cent of cryptococcal meningitis patients received substandard antifungal therapy. The overall death rate was 33%. Considering the large population size of DM II patients in China, improved attention should be paid to the high prevalence of cryptococcosis as revealed by us. We also emphasised the importance of blood glucose control for infection prevention, especially among the elderly.

Abstract
Chrysosporium species are saprophytic filamentous fungi commonly found in the soil, dung, and animal fur. Subcutaneous infection caused by this organism is rare in humans. We report a case of subcutaneous fungal infection caused by Chrysosporium keratinophilum in a 38-year-old woman. The patient presented with severe chromoblastomycosis-like lesions on the left side of the jaw and neck for 6 years. She also got tinea corporis on her trunk since she was 10 years old. Chrysosporium keratinophilum was isolated from the tissue on the neck and scales on the trunk, respectively. The patient showed satisfactory response to itraconazole therapy, although she discontinued the follow-up.

Abstract
Chronic inflammation (CI) is a risk factor for pancreatic cancer (PC) including the most common type, ductal adenocarcinoma (PDAC), but its role and the mechanisms involved are unclear. To investigate the role of CI in PC, we generated genetic mouse models with pancreatic specific CI in the presence or absence of TP53. Mice were engineered to express either cyclooxygenase-2 (COX-2) or IκB kinase-2 (IKK2), and TP53+/+ or TP53f/f specifically in adult pancreatic acinar cells by using a full-length pancreatic elastase promoter-driven Cre. Animals were followed for >80 weeks and pancreatic lesions were evaluated histologically and immunohistochemically. The presence of K-ras mutations was assessed by direct sequencing, locked nuclei acid (LNA)-based PCR, and immunohistochemistry. We observed that sustained COX-2/IKK2 expression caused histological abnormalities of pancreas, including increased immune cell infiltration, proliferation rate and DNA damage. A minority of animals with CI developed pre-neoplastic lesions, but cancer was not observed in any TP53+/+ animals within 84 weeks. In contrast, all animals with CI-lacking TP53 developed various subtypes of PC, including acinar cell carcinoma, ductal adenocarcinoma, sarcomatoid carcinoma and neuroendocrine tumors, and all died within 65 weeks. No evidence of K-ras mutations was observed. Variations in the activity of the Hippo, pERK and c-Myc pathways were found in the diverse cancer subtypes. In summary, chronic inflammation is extremely inefficient at inducing PC in the presence of TP53. However, in the absence of TP53, CI leads to the development of several rare K-ras-independent forms of PC, with infrequent PDAC. This may help explain the rarity of PDAC in persons with chronic inflammatory conditions.

Parvalbumin (PV)-positive interneurons in the hippocampus play a critical role in animal memory, such as spatial working memory. However, how PV-positive interneurons in the subregions of the hippocampus affect animal behaviors remains poorly defined. Here, we achieved specific and reversible activation of PV-positive interneurons using designer receptors exclusively activated by designer drugs (DREADD) technology. Inducible DREADD expression was demonstrated in vitro in cultured neurons, in which co-transfection of the hM3D-Gq-mCherry vector with a Cre plasmid resulted in a cellular response to hM3Dq ligand clozapine-N-oxide (CNO) stimulation. In addition, the dentate gyrus (DG) of PV-Cre mice received bilateral injection of control lentivirus or lentivirus expressing double floxed hM3D-Gq-mCherry. Selective activation of PV-positive interneurons in the DG did not affect locomotor activity or depression-related behavior in mice. Interestingly, stimulation of PV-positive interneurons induced an anxiolytic effect. Activation of PVpositive interneurons appears to impair social interaction to novelty, but has no effect on social motivation. However, this defect is likely due to the anxiolytic effect as the exploratory behavior of mice expressing hM3DGq is significantly increased. Mice expressing hM3D-Gq did not affect novel object recognition. Activation of PV-positive interneurons in the DG maintains intact cued and contextual fear memory but facilitates fear extinction. Collectively, our results demonstrated that proper control of PV interneurons activity in the DG is critical for regulation of the anxiety, social interaction and fear extinction. These results improve our fundamental understanding of the physiological role of PV-positive interneurons in the hippocampus.

Abstract
BACKGROUND Tinea capitis is very common in Western China, with the most widespread aetiological agent being Trichophyton violaceum, while Microsporum canis is prevalent in the remainder of China. Conventional diagnostics and internal transcribed spacer (ITS) sequencing analyses have proven relatively limited due to the close phylogenetic relationship of anthropophilic dermatophytes. Therefore, alternative molecular tools with sufficient specificity, reproducibility and sensitivity are necessary. OBJECTIVES To evaluate two molecular techniques [multiplex ligation-dependent probe amplification (MLPA) and rolling circle amplification (RCA)] for rapid detection of the aetiological agents of tinea capitis, T. violaceum and M. canis. METHODS Probes of RCA and MLPA were designed with target sequences in the rDNA ITS gene region. Strains tested consist of 31 T. violaceum, 22 M. canis and 24 reference strains of species that are taxonomically close to the target species. RESULTS The specificity and reproducibility of RCA and MLPA in detection of T. violaceum and M. canis were both 100% in both species. Sensitivity testing showed that RCA was positive at concentrations down to 1·68 × 10(6) copies of DNA in the TvioRCA probe, and 2·7 × 10(8) copies of DNA in McRCA. MLPA yielded positive results at concentrations of DNA down to 1·68 × 10(1) copies in the TvioMLPA probe and 2·7 × 10(2) in McMLPA. CONCLUSIONS The two techniques were sufficiently specific and sensitive for discriminating the target DNA of T. violaceum and M. canis from that of closely related dermatophytes. RCA and MLPA are advantageous in their reliability and ease of operation compared with standard polymerase chain reaction and conventional methods.

Abstract
We investigated wound tract extension of traumatic gunshot wounds in limb soft tissues as well as wound tract sonographic features and change-patterns when the limb position was changed. The experimental animals included 8 healthy crossbred pigs in the Chengdu plain region. Chinese Type 53 Carbine was used to establish the gunshot wound model of porcine soft tissues. Gunshot-injured zones in the soft tissues were dynamically observed at different time points using ultrasonic technology. Pathological examinations were performed for the corresponding regions for comparison and analysis. The internal echo of the wound tract was a pipe-like echo that changed over time. The wound tract extension changed with postural changes. The gas echo extended along the inside of the wound track, surrounding the fascia to further tissues. Ultrasonic imaging of gunshot wounds in pig soft tissues shows specific characteristics. The application of ultrasound technology may provide important imaging protection for gunshot wound debridement and postoperative unobstructed drainage, helping to improve the judgment and treatment of limb gunshot injuries.

Abstract
This study aimed to investigate the characteristic features of craniocerebral gunshot wounds by conventional ultrasound (CUS) and evaluate the efficacy of contrast-enhanced ultrasound (CEUS) in differentiation of tissue condition in wounds. Twenty crossbreed dogs (treatment: N = 15; control: N = 5) were used in the study. Pipe-shaped hyperechoes of varying size were found by CUS in most of the treated animals. The echoic areas were distinct from the neighboring brain tissue and did not change with time. CEUS revealed that the pipe-shaped echo was unenhanced in majority of the injured brains and the surrounding tissue was either heterogeneously enhanced or unenhanced. Pathological analysis confirmed that the contrast-filling-defect area indicated necrotic tissue and the heterogeneous minimally enhanced areas indicated degenerative tissue. CUS imaging enabled detection of hematomas and CEUS indicated that the filling defect was in the center of the hematoma, with enhancement gradually increasing towards the periphery. CUS could effectively detect a wound tract, hematoma, and the craniocerebral area injured by a gunshot, while CEUS could accurately reveal necrotic tissue in the injured area and differentiate the degenerative from normal tissue.

Abstract
AIM Reliable and valid screening and assessment tools are necessary to identify children at risk for neurodevelopmental disabilities who may require additional services. This study evaluated the test-retest reliability of the Capute Scales in a high-risk sample, hypothesizing adequate reliability across 6- and 12-month intervals. METHODS Capute Scales scores (N = 66) were collected via retrospective chart review from a NICU follow-up clinic within a large urban medical center spanning three age-ranges: 12-18, 19-24, and 25-36 months. On average, participants were classified as very low birth weight and premature. Reliability of the Capute Scales was evaluated with intraclass correlation coefficients across length of test-retest interval, age at testing, and degree of neonatal complications. RESULTS The Capute Scales demonstrated high reliability, regardless of length of test-retest interval (ranging from 6 to 14 months) or age of participant, for all index scores, including overall Developmental Quotient (DQ), language-based skill index (CLAMS) and nonverbal reasoning index (CAT). Linear regressions revealed that greater neonatal risk was related to poorer test-retest reliability; however, reliability coefficients remained strong. CONCLUSIONS The Capute Scales afford clinicians a reliable and valid means of screening and assessing for neurodevelopmental delay within high-risk infant populations.
