Abstract
Cancer stem cells (CSCs) are a source of tumour recurrence in patients with nasopharyngeal carcinoma (NPC); however, the function of microRNA‐124 (miR‐124) in NPC CSCs has not been clearly defined. In this study, we investigated the role of miR‐124 in NPC CSCs. qRT‐PCR was performed to measure miR‐124 expression in NPC tissues and cell lines and the effects of miR‐124 on stem‐like properties and radiosensitivity of NPC cells measured. Luciferase reporter assays and rescue experiments were used to investigate the interaction of miR‐124 with the 3′UTR of junctional adhesion molecule A (JAMA). Finally, we examined the effects of miR‐124 in an animal model and clinical samples. Down‐regulation of miR‐124 was detected in cancer tissues and was inversely associated with tumour stage and lymph node metastasis. Overexpression of miR‐124 inhibited stemness properties and enhanced radiosensitivity of NPC cells in vitro and in vivo via targeting JAMA. Up‐regulation of miR‐124 was correlated with superior overall survival of patients with NPC. Our study demonstrates that miR‐124 can inhibit stem‐like properties and enhance radiosensitivity by directly targeting JAMA in NPC. These findings provide novel insights into the molecular mechanisms underlying therapy failure in NPC.

Abstract
OBJECTIVE To analyze the diagnosis and treatment of patients with chronic renal failure complicated with novel coronavirus pneumonia, and to evaluate the effect of blood purification technology on the treatment and prognosis of such patients. METHODS Two COVID-19 cases undergoing hemodialysis with chronic renal failure were retrospectively analysed in our hospital. RESULTS Two COVID-19 patients were admitted to hospital due to cough, with or without fever. Laboratory tests showed decreased lymphocyte count, elevated PCT, IL-10, IL-6, TNF-α, IL-2R, high-sensitivity cardiac troponin I, NT-proBNP, creatinine, and urea nitrogen. Chest CT scan showed multiple blurred plaques and patchy shadows in both patients. Two patients received continuous venovenous hemodiafiltration (CVVHDF) every other day for 4-6 h everytime, in addition to the standard treatment. After CVVHDF, not only cytokines were reduced, but also liver function and cardiac function significantly improved. Both patients did not develop severe pneumonia. They were discharged on March 1, 2020 when meeting the discharge criteria. CONCLUSION Two COVID-19 patients on maintenance hemodialysis discharged after a month of hospitalization. The removal of cytokines through blood purification technology may be beneficial for the recovery of COVID-19 patients.

Abstract
Oral erythroplakia is an rare oral disorder with relatively high potential of becoming malignant. It has a lower prevalence but a higher malignant transformation rate than oral leukoplakia. The etiology and pathogenesis of the disease is so far not clear, but several studies have pointed to tobacco chewing, tobacco smoking, and betel quid chewing with or without tobacco and alcohol usage as etiologic factors.The treatment methods are mainly surgical excision operations as well as laser treatment. However, the recurrence rate and the malignant transformation rate of oral erythroplakiaare high, thus long-term close follow-up is needed. In the present article, the definition, epidemiological characteristics, clinical manifestations, histopathological characteristics, etiology and pathogenesis, diagnosis, treatment and prognosis of oral erythroplakiaare reviewed.

Abstract
Background:Platelet activation is considered as a pivot pathogenic process to be responsible for thromboembolism in antiphospholipid syndrome (APS). severalstudies shown that platelet indices including platelet distribution width (PDW), mean platelet volume (MPV), large platelet rate (P-LCR) are associated with platelet activation.Objectives:This study aims to determine the correlation between platelet indices and thrombotic events in patients with APS.Methods:Platelet activation is considered as a pivot pathogenic process to be responsible for thromboembolism in antiphospholipid syndrome (APS). severalstudies shown that platelet indices including platelet distribution width (PDW), mean platelet volume (MPV), large platelet rate (P-LCR) are associated with platelet activation.Results:A total of 207 patients [135(65.2%) female, 72(34.8%) male], medianage 35(IQR 10)] was classified into thrombotic group (n=150,72.5%) and non-thrombotic group(n=57,27.5%). PDW, MPV, P-LCR were significantly higher in thrombotic group than non-thrombotic group (13.0±3.4 vs. 11.2±7.3)p<0.001, 10.7±1.4vs.10.0±3.0,p<0.001, 30.25±11.6vs. 25.1±10.4 p<0.001, respectively]. No differences in age, WBC count, hsCRP and C3 were observed between groups. Also, HGB was found to be notably higher in thrombotic group than non-thrombotic group (143±29 vs. 132±15, p=0.001).Upon univariate logistic analysis, PDW (OR 1.554, 95%CI 1.289-1.873, p<0.001), MPV (OR 1.772, 95%CI 1.268-2.476, p=0.001), P-LCR (OR 1.089, 95%CI 1.040-1.140, p<0.001) were all significantly associated with the occurrenceof thrombosis. In multivariate logistic analysis, only PDW and positive LAwere identified to be risk factors of thrombotic events (Table 1). The ROC curve showed that PDW combinedwith positive LAwas a reliable indicator of thrombotic events with an AUC of 0.796 (95%CI 0.728-0.864). The optimal cut-off value for PDW was 12.4fl with a sensitivity of 72.0% and specificity of 77.2%.Conclusion:This study confirmed that PDW, P-LCR and MPV (especially PDW) were significantly associated with thrombotic events in APS patients, which could support the theory of platelet activation being a crucial factor of thrombosis inAPS. Caution should be raised when patients with positive LA has relatively high PDW level.Disclosure of Interests:None declared

Abstract
Background:Upadacitinib (UPA), an oral, selective JAK-1 inhibitor was effective in global ph 3 trials in rheumatoid arthritis (RA) patients with inadequate response (IR)/intolerance to csDMARDs and bDMARDs.Objectives:This Phase 3, randomized, double-blind, placebo (PBO)-controlled study assessed the efficacy and safety of UPA in combination with csDMARDs in csDMARD-IR patients with RA from China, Brazil, and South Korea.Methods:Patients were randomized 1:1 to receive UPA 15 mg once daily (QD) or PBO in combination with csDMARDs. The primary endpoint was ACR20 response at Week 12, using non-responder imputation.Results:338 patients were randomized, and 310 (91.7%) completed Week 12. At Week 12, statistically significantly more patients receiving UPA vs PBO achieved the primary endpoint of ACR20 (71.6% vs 31.4%, p<0.001). UPA also demonstrated statistically significant improvements in all ranked secondary endpoints vs PBO at Week 12 (Table 1), including mean change in DAS28(CRP), HAQ-DI, and SF-36 PCS, and patients achieving DAS28(CRP) ≤3.2, DAS28(CRP) <2.6, and CDAI ≤10. Greater responses were also seen with UPA vs PBO for other key secondary endpoints including ACR50 and ACR70. Onset of UPA action was rapid with more patients on UPA achieving ACR20 by Week 1 (25.4% vs 5.9%, p<0.001). The frequency of AEs (61.5% vs 49.1%) and serious AEs (7.1% vs 3.0%) was higher with UPA vs PBO. The frequency of AEs of special interest was generally similar between UPA and PBO, with the exception of herpes zoster (1.8% vs 0.6%), hepatic disorders (9.5% vs 7.1%), neutropenia (3.0% vs 0%), and elevated creatine phosphokinase (1.8% vs 0.6%), which were higher with UPA. One case of breast cancer (on Day 1 of study) and one VTE (pulmonary embolism and deep vein thrombosis in a patient with history of deep vein thrombosis) were reported with UPA treatment.Table 1.Efficacy endpoints at Week 12EndpointaUPA 15 mg QD (n=169)PBO(n=169)Primary endpointACR20, %71.6***31.4Secondary endpointsΔ DAS28(CRP)-2.56***-0.95Δ HAQ-DI-0.62***-0.18Δ SF-36 PCS8.93c***3.36dDAS28(CRP) ≤3.2, %46.2***13.6DAS28(CRP) <2.6, %29.6***5.3CDAI ≤10, %35.5***11.2ACR50, %b40.8***8.3ACR70, %b21.3***3.6ACR20 at Week 1, %b25.4***5.9***p<0.001 vs PBOaNRI for binary endpoints; ANCOVA with multiple imputation for DAS28(CRP) and HAQ-DI; mixed model repeated measures for other continuous endpointsbUnranked secondary endpoint.cn=143.dn=149Conclusion:Efficacy of UPA was demonstrated in this csDMARD-IR population from China, Brazil, and South Korea.

Abstract
Background:Osteoarthritis (OA) of the knee and hip is a leading cause of disability worldwide, particularly due to the primary symptom of pain in the weight-bearing joints. There is limited data that characterizes patients who experience moderate to severe pain despite analgesic treatment in China.Objectives:This study estimates the real-world prevalence of inadequate pain relief (IPR) among patients with knee and/or hip OA who have been prescribed analgesic therapy and characterizes this patient population. The study was conducted in China, the Philippines, Thailand, Russia, and Mexico. This abstract presents results from China.Methods:This is a multinational, multi-site, cross-sectional, observational study. Physicians managing patients with OA were recruited and asked to enroll patients over 50 years of age with knee and/or hip OA who had been prescribed topical and/or oral pain medication for at least 30 days prior to study visit. Patients completed a one-time assessment of pain, function, and health-related quality of life (HRQOL) using patient reported outcome (PRO) instruments. Physicians abstracted data from patient charts. IPR was defined as an average pain score of >4/10 on Brief Pain Inventory Question #5 (average pain). Statistical tests including chi-square for categorical variables and Mann-Whitney Wilcoxon test for continuous variables were conducted to assess differences in demographic and clinical characteristics as well as PROs between patients with and without IPR. A multivariate regression analysis was conducted to assess the relationship between IPR and PROs.Results:571 patients treated at 10 hospital centers in China were enrolled. 73% were female, the mean (SD) age was 62 (8.32) years. The number of years with OA ranged from less than one year to over 37 years, suggesting a broad sample of patients. Most patients were impacted by knee OA only (90%). Almost half (43%) of the study population met the definition of IPR. Patients with IPR tended to be older, have greater prevalence of obesity, have more comorbidities, and had longer disease duration. The majority (98%) of patients were receiving nonsteroidal anti-inflammatory drugs (NSAIDS), followed by chondroprotective medications (23%). However, more patients with IPR mentioned being dissatisfied with treatment (38% vs. 21%). After adjusting for covariates, patients with IPR reported worse HRQOL, more functional limitations, and reduced work productivity compared to patients without IPR.Conclusion:IPR is highly prevalent among individuals with knee and/or hip OA in China and is associated with decreased HRQOL and work productivity, impaired function, and treatment dissatisfaction. Developing awareness among healthcare professionals about the presence and potential impact of IPR is important for the ultimate improvement of OA patient management.PROmean (SE)No IPR(N=328)IPR(N=243)EQ-5D Index0.72 (0.01)0.49 (0.02)EQ-5D VAS72.3 (0.85)65.5 (1.00)WOMAC Pain Subscale13.1 (0.78)22.7 (1.52)WOMAC Stiffness Subscale4.2 (0.27)7.4(0.51)WOMAC Physical Function Subscale44.8 (2.61)76.9 (5.07)Work Productivity Loss30.0 (4.07)47.5 (10.46)Multivariate analysis adjusted for age, year since OA diagnosis/follow-up, gender, BMI, number of medication classes, insurance, physician specialty/academic responsibilities, number of affected joints, diabetes, CVD, hyperlipidemia/hypertension, and depression.

Abstract
Background:Malignant neoplasms is the second most common non-SSc associated cause of death in SSc patients, only second to infection. And among all the neoplasms, lung cancers are the most common, which is in the urgent need of attention from clinicians.Objectives:To analyze the clinical features of patients of SSc with lung cancer.Methods:Medical records of inpatients admitted in Peking Union Medical College Hospital from March 1992 to December 2018, were collected and analyzed, including the clinical manifestation, laboratory data, radiological images, pathology. SSc patients without lung cancer during the same period, matched by age and gender, were selected as the controls.Results:Nineteen SSc patients with complete medical records were identified, with 17 (89.5%) females and 2 (10.5%) males. The mean age of SSc onset was 37.8±12.0) years old and of lung cancer diagnosis was (54.4±10.2) years old. One (5.3%) had a smoking history. Eight (42.1%) patients had family history of cancer, which was significantly higher than those without lung cancer (4 patients, 5.3%, P<0.001). The proportion of limited cutaneous SSc (lcSSc) were 63.2% among these patients, and 18 (94.7%) had interstitial lung disease (ILD), the difference between the two groups was not statistically significant (P = 0.259 and 0.051, respectively). All ILD was diagnosed before the onset of lung cancer, with a median interval of 9.2 (range 1.6-28.1) years. SSc patients with lung cancer had less myositis than control group (0% vs. 27.6%, P = 0.032), yet no significant differences were identified in Raynaud’s syndrome, esophageal involvement, digital ulcers, pulmonary hypertension, telangiectasia and arthritis. All patients developed lung cancer after the diagnosis of SSc, with a median interval 10.5 (range 2.0-36.2) years. In most of them(18, 94.7%), lung cancer happened after at least 6 years of SSc onset. Newly happened cough (9 patients), worsening decrease in activity endurance (3), chest pain (2), hemoptysis (2), nodes in lung through regular CT scans (3) were the first presentations of lung cancer. Ten(62.5%) neoplasms developed in the lower lobes of the lung, while 3 was in the upper lobes, one in the lingual lobe, and one in the left pulmonary hilum, and 3 were unknown. The median survival of the case group were 31.4 years, while the median survival of the control group was not reached. Eight patients tested EGFR gene mutation or ALK gene rearrangement, and only 2 were positive.Conclusion:It is not uncommon that SSc could be concomitant with lung cancer, especially for those with long disease duration and family history of malignancy. Due to the subtle onset of lung cancer, clinicians should pay attention to it during clinical practice.References:[1]Hu S et al.

Abstract
Background:Polyarteritis nodosa (PAN) is a systemic necrotizing vasculitis that mainly affects medium-sized muscular arteries. The coronary artery could be affected. Some severe cases can lead to spontaneous coronary artery dissection (SCAD) and about 0.02% will die abruptly. Early diagnosis will improve prognosis, but relative studies are all case reports so far.Objectives:To investigate the clinical characteristics, risk factors and outcome of patients with polyarteritis nodosa (PAN) complicated with coronary artery lesions in China.Methods:Data of 158 patients with PAN who were admitted to Peking Union Medical College Hospital from September 1986 to September 2019 were retrospective collected. Data were analyzed and compared according to with and without coronary artery lesions due to PAN.Results:17 (10.8%) patients with PAN had the coronary artery lesions due to PAN. The age at coronary artery lesion was 36.9±10.3 years. 12 (70.6%) patients were male. There are not statistical differences between two groups in common risk factors of coronary arterial atherosclerosis including smoking, hypertension, diabetes mellitus and hyperlipidemia. Most of them are multi-vessel lesions (8 cases are triple-vessel lesions and 3 cases are bi-vessel lesions). Type of coronary artery affected is shown mainly in stenosis (13 cases). Myocardial infarction are shown in 8 cases (47.1%). Compared to patients without coronary artery lesions, patients with coronary artery lesions had less nervous system involvement (17.6% vs.46.8%) and elevated number of leukocyte (17.6% vs.56%). Besides, patients with coronary artery affected exhibit more cranial and carotid artery involvement(29.4% vs. 5.0%), renal artery involvement (41.2% vs.17.0%), coeliac artery involvement (58.8% vs.27.0%), new onset hypertension (47.1% vs.14.5%), renal infarction (27.3% vs.5.4%, ) and higher proportion of 2009 Five-factor score (FFS)≥2 (62.5% vs.15.6%). All patients with coronary artery lesions received at least moderate dose of prednisone and CTX except one refused medication. 3 cases underwent interventional therapy. Stent placement was performed on 2 of them, and in-stent restenosis was appeared in a patient one year later. 2 cases died,one for vascular rupture after coronary aneurysmsutrue plus coronary artery bypass grafting, another for myocardial infarction after stopping immunosuppressant therapy himself.Survival analysis showed patients with digital g angrene had poor prognosis though no significant difference(p=0.055).Conclusion:PAN with coronary artery lessions are not uncommon. These patients exhibit young age, more proportion of multi-vessel of coronary artery involvement, more combined involvments of other organ arteries and more severe disease.References:[1]Munguti CM, Ndunda PM, Muutu TM.

Abstract
Background:The presence of circulating antinuclear antibodies (ANAs) is a hallmark of immune dysregulation and malfunction in patients with systemic sclerosis (SSc)[1]. A variety of ANAs[2], including anti-centromere antibody, anti-topoisomerase I antibody, and anti-RNA polymerase III antibody, are associated with unique sets of disease manifestations and widely used in routine clinical practice for diagnosis, clinical subgrouping, risk stratification and prediction of future organ involvements and prognosis in SSc patients[3,4].Objectives:This study aimed to investigate the clinical features of SSc patients with negative ANAs in a European League Against Rheumatism Scleroderma Trials and Research Group (EUSTAR) and Chinese Rheumatism Data Center (CRDC) multi-center cohort in China.Methods:Patients were prospectively recruited between April 2008 and June 2019 based on the EUSTAR database and CRDC multi-center cohort from 154 clinical centers nationwide, all of whom fulfilled the 2013 ACR/EULAR classification criteria for systemic sclerosis. Antinuclear antibody testing result was intensively collected. Demographic, clinical, and laboratory data were compared between ANA-positive SSc patients and those with negative ANAs. T-test and chi-square analysis were performed in the comparisons.Results:Antinuclear antibodies were detected in 2129 out of 2809 systemic sclerosis patients enrolled in the multi-center cohort and 4.2% of them were negative. There was significant difference between patients with negative and positive ANAs based on gender (29/60 vs 294/1746, p<0.001). The presence of Raynaud’s phenomenon is less common (71.8% vs 99.8%, p<0.001) in the ANA-negative patients. In addition, compared with ANA-positive patients, the incidence of certain critical organ involvements, including gastroesophageal reflux (5.6% vs 18.5%, p=0.002), interstitial lung disease (65.2% vs 77.9%, p=0.015) and pulmonary arterial hypertension (11.5% vs 29.0%, p=0.006) were significantly lower in ANA-negative patients than in the positive group. The proportion of IgG elevation, an indicator of disease activity and severity of inflammation, was significantly lower in the ANA-negative patients than that in the positive group (14.3% vs 41.2%, p<0.001), while no significant differences were found in other inflammatory indicators and skin scores.Conclusion:This study describes the clinical features of SSc patients with negative ANAs, which have been rarely mentioned or focused in existing studies. Antinuclear antibody is proved to be strongly associated with the clinical manifestations of systemic sclerosis patients and ANA-negative SSc patients tend to be in relatively milder conditions, including a less common involvement of critical organs and a more temperate inflammatory severity.References:[1]Seri, Jeong, Dahae, et al.

Abstract
Background:Primary Sjögren’s syndrome(pSS) is a classical systemic autoimmune disease. Thrombocytopenia is one of the hematological manifestations of pSS with great challenges in clinic.Objectives:To identify the candidate genes and functionally enriched pathways in the immune genesis and progression of primary Sjögren’s syndrome (pSS) associated thrombocytopenia.Methods:High-throughput sequencing was performed on 3 patients with pSS, 3 patients with pSS associated thrombocytopenia and 3 healthy individuals. The differentially expressed genes (DEGs) were identified, and function enrichment analyses were processed. The protein-protein interaction network (PPI) was constructed, followed by calculation of topological characteristics and sub-module analysis in order to obtain hub DEGs. The expression of some hub genes was verified by Real-Time PCR in 24 pSS patients.Results:A total of 19 DEGs were identified. The enriched functions and pathway of the DEGs include Toll-like receptor signaling pathway, Salmonella infection, Viral protein interaction with cytokine and cytokine receptor, NF-kappa B signaling pathway and Human cytomegalovirus infection. Seven hub genes (TNF, IL1B, CXCL8, CCL3, CCL4, CCL3L1, CCL4L1) were identified and pathway enrichment analysis revealed that these genes were mainly enriched in toll-like receptor pathway. The relative expression of the CXCL8 mRNA in B-lymphocytes in patients with pSS associated thrombocytopenia was higher than that in the pSS without thrombocytopenia group. No differences were observed in the IL-1β or TNFα expression between these two groups.Conclusion:PSS associated thrombocytopenia might be a subset characterized by a systemic inflammatory state. The identification of upregulated genes involved in thrombocytopenia of pSS provides insight in disease pathogenesis and opens avenues for the design of novel therapeutic strategies.References:[1] Fox RI: Sjögren’s syndrome.

Abstract
Background:Photoacoustic imaging (PAI), a new imaging technique which can be integrating with ultrasound (US) imaging, has shown potential in visualizing small joints. We have developed a multimodal photoacoustic/ultrasound (PA/US) imaging system, equipped with a handheld probe, which can provide dual-wavelength PA/US imaging to identify the micro-vessels of the inflamed articular regions and measure the oxygenation level of human inflamed synovium.Objectives:To validate the potential value for RA of the imaging system.Methods:A total of 32 RA patients received PA/US examination on seven small joints (MCP2, MCP3, PIP2, PIP3, MTP2, MTP5, and wrist of the clinically dominant side). The 0-3 score was used to semi-quantify the PA and PD signals of the inflammatory articular lesions, and the sums of PA and PD scores (PA-sum and PD-sum) were utilized. The relative oxygen saturation (SO2) values of the inflamed regions were measured by calculating the ratio of PA signals at the wavelength of 750nm and 830nm. All the patients were classified to 3 PA+SO2 patterns (Pattern 1: no or minimal PA signals; Pattern 2: evident PA signals and hyperoxia; Pattern 3: evident PA signals and hypoxia). The correlations between imaging scores and laboratory data, as well as clinical scoring systems were assessed.Results:A total of 32 patients of RA were recruited aged from 25-71 years-old were examined. PD-sum had moderate correlation with the clinical scores (r=0.529, 0.546, 0.490, 0.493 for DAS28ESR, DAS28CRP, SDAI, CDAI), moderate correlations with TJC (r=0.575) and SJC (r=0.491), fair correlation with VAS (r=0.239), poor correlation with PGA (r=0.153), and moderate correlation with EGA (r=0.457). The PA-sum had substantial correlations with the clinical scores (r= 0.699, 0.746, 0.723, 0.736 for DAS28ESR, DAS28CRP, SDAI, CDAI), substantial correlations with TJC (r=0.787) and SJC (r=0.694), moderate correlations with VAS (r=0.544) and PGA (r=0.529), and substantial correlation with EGA (r=0.708).Ten patients were classified as Pattern 1, 12 as Pattern 2, 9 as Pattern 3. The PA+ SO2 patterns presented substantial correlations with the clinical scores (DAS28ESR r=0.690, DAS28CRP r=0.782, SDAI r=0.805, CDAI r=0.799, SJC r=647, TJC r=0.676, respectively), substantial correlation with VAS (r=0.714), and moderate correlation with PGA (r=0.476) and EGA (r=0.502). Significant differences between those who were classified as hypoxia and hyperoxia with evident PA signals, were detected in VAS (p=0.020) and PGA (p=0.026).Conclusion:The PA-sum scores and the PA+SO2 patterns can be utilized as objective imaging parameters reflecting the disease activity of RA. PAI may serve as a supplement to conventional US examinations for RA patients.References:[1]Backhaus, M., et al., Evaluation of a novel 7-joint ultrasound score in daily rheumatologic practice: a pilot project.

Abstract
Background:Polyarteritis nodosa (PAN) is a segmental, necrotizing vascular disease that primarily impacts medium-sized muscle arteries. The estimated annual incidence of PAN is still lacking in China. Digital gangrene is an ischemic manifestation of the limb. However, the causes and the treatment methods vary from case to case, and the outcome is unpredictable. These features emphasize the need to identify measurable variables that accelerate digital gangrene development in PAN patients. However, little effort has been made to identify the clinical and laboratory factors that affect PAN patients with digital gangrene to anticipate their natural history and response to therapy.Objectives:Many patients with polyarteritis nodosa (PAN) complicated with digital gangrene have poor outcomes and related research information is limited. This study was carried out to identify the associated risk and prognostic factors.Methods:We conducted a retrospective study of 148 PAN patients admitted to Peking Union Medical College Hospital (PUMCH) from September 1986 to December 2018. The characteristics, therapeutic regimens, and outcome data for patients with and without gangrene were compared. The Kaplan–Meier method and Cox hazard regression model were used to evaluate the prognostic factors.Results:Forty-seven (31.8%) PAN patients had digital gangrene complications. The average age was 40.4±17.9 years and the average disease duration was 11 (4-27) months. The presence of digital gangrene was correlated with smoking history [odds ratio (OR), 4.27; 95% confidence interval (95% CI), 1.56-11.66] and eosinophil elevation (28.12; 10.30-76.8). Thirty-two (68.1%) gangrene patients received methylprednisolone pulse therapy and all of these patients were treated with cyclophosphamide. Nine patients suffered irreversible organ injury and two died. Disease duration ≥ 24 months and elevated serum C-reactive protein (CRP) were identified as hazardous factors for poor prognosis in patients with gangrene (P=0.003, HR=8.668, 95% CI 2.11, 35.55 andP=0.042, HR=27.062, 95% CI 1.13, 648.57, respectively).Conclusion:Smoking history and eosinophil elevation in PAN patients were more prone to digital gangrene and high serum CRP level predicted poor outcomes. PAN patients with smoking history and elevated eosinophils need to be seriously evaluated by clinicians. Furthermore, the CRP level should be efficiently controlled for good prognosis.References:[1]De Virgilio A, Greco A, Magliulo G, Gallo A, Ruoppolo G, Conte M, et al.

Abstract
Background:The activation of self-specific T cells is essential in pathogenesis of Takayasu arteritis (TAK). Dendritic cell (DC) plays an indispensable role as the only antigen presenting cell for initial T cell, and Toll-like receptors (TLRs) are common source of activation signals for DCs. Then we speculate that there are activation of TLRs in TAK patients.Objectives:To investigate the activation of TLRs in TAK patients.Methods:Twenty-seven TAK patients were enrolled during April to October in 2019, with diagnosis met the 1990 criteria of American College of Rheumatology. Patient were divided into groups by the disease activity and medication history. Disease activity was assessed by the 1994 NIH criteria. Quantitative Real-time Polymerase Chain Reaction (RT-qPCR) was used to analyze the mRNA relative abundance of 28 target genes in peripheral blood mononuclear cells (PBMCs). Differences between groups and correlation between any two genes were analyzed.Results:The demographic data and clinical features of TAK patients were shown in Table 1. (1) Compared with health control (HC) group, mRNA abundance ofTLR2, TLR4, P50, P65, IκBα, CTLA4, CD3,andBCL6in untreated TAK group was upregulated (<0.05), whereas mRNA abundance ofCD40was downregulated (p <0.05). (2) Compared with HC group, mRNA abundance ofTLR2, TLR4, IκBα, PD-1 and BCL6in treated TAK group was upregulated (p <0.05), whereas mRNA abundance ofLAG3, CD40andTCRwas downregulated (p <0.05). (3) Compared with untreated TAK group, mRNA abundance ofP50, P65, CD28, CTLA4, TLR2, TLR4, IκBα, PD-1 and RORCwas upregulated in treated TAK group (p <0.05). (4) Compared with non-active treated TAK group, mRNA abundance ofp50, CD28, TCR, GATA3, RORC and FOXP3was upregulated in nonactive treated TAK group (p <0.05). BCL6 showed correlation with the TLRs-NFκB pathway.

Abstract
The clinical outcome of oral squamous cell carcinoma (OSCC) has not improved in recent years, mainly due to the limited effective targeted therapy that has been applied. Recently, a transcriptional coactivator, YAP, has been shown to have a key regulatory role in malignant progression in multiple cancers, including OSCC. But pharmacologically targeting YAP or the Hippo pathway, which is the main signaling pathway regulating YAP, has been proven to be challenging. Therefore, uncovering YAP upstream regulators in cancer would identify novel therapeutic targets for treatment of YAP-sustained cancers. Here, we showed that YAP was overactivated in OSCC and that high YAP activity in patients with OSCC was associated with malignant progression and poor survival. We uncovered that GPR39 (a G protein-coupled receptor) was overexpressed in OSCC, that the expression level of GPR39 was correlated with the activity level of YAP, and that the high GPR39 expression was associated with malignant progression and poor survival in patients with OSCC. Moreover, we found that GPR39 regulated YAP through a Gαq/11-RhoA-dependent signaling pathway. Importantly, inhibition of GPR39 resulted in YAP-sustained OSCC growth inhibition. Our findings suggest that GPR39 is a potential therapeutic target for OSCC treatment with itself as a biomarker.

Abstract
Bacillus Calmette‑Guérin (BCG) is considered to be a successful biotherapy for treating bladder cancer (BCa). However, the underlying mechanisms of BCG have not been completely clarified, to date. The role of macrophages in BCG therapy for BCa has still not been determined in vivo. In the present study, the role and potential mechanism of BCG (0.25, 1.25 and 6.25 µg/mouse; intravenous) immunotherapy for BCa was investigated in a NOD/scid IL2Rg‑/‑ (NSI) mouse model by targeting macrophages in vivo. Notably, it was observed that NSI mice with T24 BCa cells displayed high levels of the macrophage marker CD11b+ F4/80+ after injection via the tail vein of live BCG, as well as a significant reduction in tumor volume. The levels of the inflammatory and macrophage maturation cytokines, such as tumor necrosis factor‑α, interleukin (IL)‑1β, IL‑6, IL‑12P70, TNF superfamily member 11 and monocyte chemotactic protein 1, were significantly increased in the serum and the tumor supernatant compared to that in normal control subjects. Furthermore, BCG promoted the expression of the pro‑differential genes Spi‑1 proto‑oncogene, early growth response protein 1, nuclear factor (NF)‑κB and proto‑oncogene c‑Fos in bone marrow. In conclusion, these observations indicate that the injection of live BCG can target macrophages against bladder tumor growth in vivo. The mechanism is likely related to the promotion of macrophage maturation, immune activation and increased numbers of macrophages infiltrating the bladder tumor.

Abstract
Aim: To describe the direct healthcare costs associated with repeated cytotoxic chemotherapy treatments for recurrent high-grade serous cancer (HGSC) of the ovaries. Patients & methods: Retrospective review of 66 women with recurrent stage III/IV HGSC ovarian cancer treated with repeated lines of cytotoxic chemotherapy in a Canadian University Tertiary Center. Results: Mean cost of treatment of first relapse was CAD$52,227 increasing by 38% for two, and 86% for three or more relapses with median overall survival of 36.0, 50.7 and 42.8 months, respectively. In-hospital care accounted for 71% and chemotherapy drugs accounted for 17% of the total costs. Conclusion: After the third relapse of HGSC, cytotoxic chemotherapy did not prolong survival but was associated with substantially increased healthcare costs.

Abstract
Background Acute coronary syndrome (ACS) is the most serious type of coronary heart disease and is a global medical burden. The pathogenesis of ACS is very complex and still poorly understood. Epidemiologic studies have revealed that the manifestation of ACS are the results of the interactions between multiple environmental and genetic factors. The present study aimed to investigate the role of polymorphisms of MTHFR C677T and ALDH2 Glu504Lys as risk factors for ACS in a Hakka population in southern China. Methods Between September 1, 2015 and October 31, 2017, a total of 1957 individuals, including 860 ACS patients and 1097 controls were recruited. Blood samples were collected and genotypes were determined by DNA microarray chip method and direct sequencing method. Results For the MTHFR C677T polymorphism, frequencies of CC, CT, and TT genotypes were 53.60% versus 55.33, 39.53% versus 38.65 and 6.86% versus 6.02% in patients with ACS versus controls, respectively(p > 0.05). The differences in genotype frequencies between the ACS patients and controls in the three genetic model were not statistically significant. For the ALDH2 Glu504Lys polymorphism, the frequencies of ALDH2*1*1, ALDH2*1*2, and ALDH2*2*2 genotypes were 48.72, 42.67 and 8.6% in the ACS patients, respectively, while these were 53.33, 39.11 and 7.57% in the controls, respectively, showing no significant difference in the distribution of the ALDH2 genotype between the groups. Using the wild genotype ALDH2*1*1 as reference, relative risk analysis revealed a slightly increased risk for ACS in individuals with the ALDH2*1*2 plus ALDH2*2*2 genotypes (odds ratio (OR) = 1.203, 95% confidence interval (CI) = 1.006–1.438, p = 0.043). In a multivariate logistic regression model, even after adjusting for potential covariates, the association between ALDH2 *2 allele and ACS remained significant (OR = 1.242, 95% CI = 1.045–1.561, p = 0.038). Conclusions We present findings regarding the possible clinical impact of the ALDH2*2 variant on ACS patients in a Hakka population in southern China and our findings might help to stratify the high-risk ACS patients and implement appropriate strategies for this genetic subpopulation to ultimately guide the precision preventive procedures in the future.

Abstract
Oral lichen planus (OLP) is a common chronic inflammatory disease of oral mucosa. The diagnostic criteria of OLP is the cornerstone of clinical diagnosis and treatment and scientific research. However, there are various understandings of the diagnostic criteria in China. Thus several questions need to be answered, for example, how to combine the international diagnostic criteria with China's specific conditions, how to apply the criteria into clinical practice, and how to use the criteria guiding clinical work and scientific research in China. The authors of this article systematically introduced and discussed the development, content and difference of the international diagnostic criteria of OLP. We proposed "23 Princeples" for the selection of biopsy indications in OLP diagnosis based on authors' personal experiences in clinical and basic research and the actual conditions of Chinese clinicians. We also express our own views and suggestions about some other hot issues associated with OLP diagnosis.

Abstract
Objective This study aimed to identify the clinical characteristics and prognostic factors of systemic lupus erythematosus with transverse myelitis (SLE-TM) in a relatively large patient series. Methods This retrospective study considered 45 SLE-TM individuals treated as inpatients and outpatients at Peking Union Medical College Hospital between 1993 and 2018. SLE-TM patients were compared with 180 controls, and SLE-TM patients with neuromyelitis optica spectrum disorder (NMOSD) were compared to those without NMOSD. Results Compared to controls, the SLE-TM group frequently had a fever and had a significantly higher positive rate of anticardiolipin and lupus anticoagulant. Among the 45 patients, 22 met the NMOSD criteria. Compared to non-NMOSD patients, NMOSD patients had a lower incidence of rash ( p = 0.023), serositis ( p = 0.042) and renal disorder ( p = 0.073); a lower prevalence of decreased complement ( p = 0.083); and lower rates of positive anti-dsDNA ( p = 0.074) and anti-Sm ( p = 0.042). Among 22 SLE-TM patients with NMOSD, 18 underwent aquaporin 4 antibody testing, with 11 showing positive results. Out of the 45 patients, 39 were given methylprednisolone pulse treatment. After treatment, 32 patients had lower-limb muscle strength recovery (recovered group), whereas 13 had no change and persistent severe neurological deficits (non-recovered group). Compared to the recovered group, the non-recovered group were younger ( p = 0.002), had a higher likelihood of having a fever ( p = 0.020), initial severe myelitis ( p < 0.001), long spinal segment involvement ( p = 0.017) and higher C-reactive protein levels ( p = 0.020). Methylprednisolone pulse given within two weeks of onset was more frequent in the recovered group than in the non-recovered group ( p = 0.082). Conclusions Disease characteristics differed between SLE-TM patients with and without NMOSD. SLE and NMOSD tended to be co-morbidities. Initial severe neurological impairment, extensive spinal cord lesions, hyper-inflammation and delayed steroid impulse treatment could be predictors of poor outcome for SLE-TM.

Abstract
INTRODUCTION AND OBJECTIVES The exact role of E-cadherin in non-muscle-invasive bladder cancer (NMIBC) is still unknown, and the aims of this study were to prove whether reduced E-cadherin expression can be a prognostic factor in patients with NMIBC. MATERIALS AND METHODS A meta-analysis was conducted to assess the prognostic value of reduced E-cadherin expression in NMIBC. The PubMed, Embase and Web of Science databases were included in the study search. RESULTS Fifteen studies with a total of 1538 NMIBC patients were included. The results showed that reduced E-cadherin expression was significantly associated with poor recurrence-free survival (RFS) (pooled HR 2.16, 95% CI 1.22-3.85) and progression-free survival (PFS) (pooled HR 1.91, 95% CI 1.52-2.40) in NMIBC patients. CONCLUSION E-cadherin can be a prognostic factor for patients with NMIBC.

Abstract
Ninety-four putative G protein-coupled receptors (GPCRs) were identified in the Musca domestica genome. They were annotated and compared with their homologues in Drosophila melanogaster. Phylogenetic analyses of the GPCRs from both species revealed that several family members shared a closer relationship based on the domain architecture. The expression profiles of these genes were examined by quantitative real-time PCR amongst three strains of the house fly, a near-isogenic line strain with imidacloprid resistance (N-IRS), the corresponding susceptible strain (CSS) and another strain derived from field populations with imidacloprid resistance (IRS). We found that five GPCR genes were upregulated in the N-IRS and eight GPCR genes were upregulated in the IRS strains compared to the CSS strain. The transgenic lines of D. melanogaster with the GPCR genes (LOC101899380 in the N-IRS strain and LOC101895664 in the IRS strain) exhibited significantly increased tolerance to imidacloprid, and higher expression of cytochrome P450 genes. Bioinformatic analysis of LOC101899380 was carried out based on its full-length nucleic acid sequence and putative amino acid sequence, and it was named Methuselah-like10 (Mthl10) owing to its homology with D. melanogaster Mthl10. A cell-base cell counting kit-8 toxicity assay demonstrated that the expression of the GPCR gene LOC101899380 in Spodoptera frugiperda (Sf9) cells using a baculovirus-mediated expression system can elevate the cell tolerance to imidacloprid, indirectly supporting the hypothesis that the GPCR gene LOC101899380 plays some role in imidacloprid resistance. These results should be useful for furthering understanding of the regulatory pathway by which house flies develop resistance.

As a current popular quality assessment approach, focusing on qualitative and quantitative analysis of certain compounds contained in herbal medicine has been widely used for the sake of expediency rather than being a practical and realistic way. However, this method does not take the existence of other constituents into account. Comparatively, the chromatographic fingerprint of the components is a more suitable approach to holistically assess the quality of herbal drugs. Fructus xanthii is a well-known herbal drug listed in all editions of the Chinese Pharmacopoeia. However, there is no quality evaluation method given in its monograph, even for the above-mentioned expediency. This paper reports an HPLC fingerprinting method for quality evaluation of F. xanthii. The HPLC profiles of 27 batches of commercial samples were further analyzed using chemometric methods, including similarity evaluation and principal component analysis. As a result, the established HPLC fingerprint contained 23 characteristic peaks; therein, 13 peaks were unambiguously assigned by comparing their retention times and UV spectra with those of reference compounds, and five peaks were tentatively identified on the basis of their MS/MS fragmentation patterns and UV spectra. Moreover, it could be clearly observed that caffeoylquinic acid and its analogs predominate in F. xanthii. Except for three samples identified as outliers, 24 other commercial samples displayed similar HPLC profiles, indicating that the quality of the herbs from different markets is stable and consistent.

Abstract
Objectives To investigate the prevalence, clinical characteristics, and prognosis of thrombocytopenia (TP) in Chinese patients with systemic lupus erythematosus (SLE). Methods The study was conducted based on the Chinese SLE Treatment and Research group (CSTAR) registry. Thrombocytopenia was defined as the platelet count<100,000/mm3 at enrollment. Severe thrombocytopenia was defined as the platelet count<50,000/mm3. The prevalence of SLE-related TP, the associations of thrombocytopenia with demographic data, organ involvements, laboratory findings, disease activity, damage, and mortality were investigated. Results Of 2104 patients with SLE, 342 patients (16.3%) were diagnosed with thrombocytopenia. The prevalence of neuropsychiatric SLE, vasculitis, myositis, nephritis, mucocutaneous lesions, pleuritis, fever, leukocytopenia and hypocomplementemia were significantly higher in patients with thrombocytopenia (p<0.05). SLE disease activity index (SLEDAI) was significantly higher in patients with thrombocytopenia (p<0.05). Multivariate analysis showed that leukocytopenia (OR = 2.644), lupus nephritis (OR = 1.539), hypocomplementemia (OR = 1.497) and elevated SLEDAI (OR = 1.318) were independently associated with thrombocytopenia (p<0.05). Long disease duration (OR = 1.006) was an independent risk factor of severe thrombocytopenia, while anti-rRNP (OR = 0.208) was an independent protective factor of severe thrombocytopenia (p<0.05). Long disease duration was an independent risk factor of mortality in patients with thrombocytopenia (RR = 1.006). The 6-year survival of patients with thrombocytopenia was significantly lower than patients without thrombocytopenia (88.2% vs. 95.5%). Conclusions Thrombocytopenia was a common manifestation of SLE and was associated with leukocytopenia, nephritis and severe disease activity. Severe thrombocytopenia tended to occur in long-term and relatively inactive SLE. Patients with SLE-related thrombocytopenia has a decreased long-term survival rate. Long disease duration was an independent risk factor of mortality in patients with thrombocytopenia.

Abstract
OBJECTIVE To investigate the biological role of micro-ribonucleic acid (miR)-29a in non-small-cell lung cancer (NSCLC). PATIENTS AND METHODS 55 cases of NSCLC tissue specimens and paired normal lung tissue specimens collected in the Department II of Oncology, Ruikang Hospital Affiliated to Guangxi University of Chinese Medicine from July 2012 to April 2015 were randomly included. The fluorescent quantitative polymerase chain reaction, Western blotting, and immunohistochemistry were performed to detect the expression levels of miR-29a and metastasis suppressor 1 (MTSS1). Pearson correlation analysis was utilized to investigate the relationship between miR-29a expression and MTSS1 expression in NSCLC tissues, and the Kaplan-Meier survival curves were constructed to analyze the association of miR-29a expression with the survival time of NSCLC patients. A54 proliferation and invasion abilities were measured by means of plate clone formation assay, and transwell assay after the miR-29a was suppressed by miRNA inhibitor. Luciferase assay was used to detect the target gene of miR-29a. RESULTS In NSCLC tissues, the miR-29a expression level was higher than that in normal lung tissues (p<0.05), while the expression level of MTSS1 protein was remarkably lower than that in normal lung tissues (p<0.05). The median survival time of the patients was 15.1 months in high miR-29a expression group and 18.3 months in low miR-29a expression group (p<0.05). The miR-29a expression was negatively correlated with the expression level of MTSS1 protein in NSCLC tissues (r=-0.762, p<0.05). Luciferase results suggest that miR-29a binds to the promoter region of MTSS1 and inhibits its transcription level. The expression of MTSS1 protein was up-regulated notably after miR-29a knockdown by an inhibitor. It was revealed in the results of transwell assay and plate clone formation assay that the proliferative and invasive capacity of A549 cells was significantly decreased after knockdown of miR-29a. CONCLUSIONS The transcribed miR-29a down-regulates the protein level of MTSS1, suppressor of tumor proliferation and invasion, thereby promoting the proliferative and invasive capacity of NSCLC cells. Both miR-29a and MTSS1 are expected to become potential therapeutic targets for NSCLC.

Abstract
OBJECTIVES The objective of this study was to investigate risk factors of microvascular involvement and survival in Chinese patients with primary antiphospholipid syndrome. METHODS In this single-center, retrospective study, we enrolled 112 patients with a confirmed diagnosis of primary antiphospholipid syndrome who were admitted to Peking Union Medical College Hospital from January 2004 to December 2016. Demographic data, clinical characteristics, laboratory results, and follow-up records were collected. RESULTS A total of 112 patients with primary antiphospholipid syndrome were studied. Microvascular involvement was identified in 21 patients (18.75%). Patients with microvascular involvement experienced fewer episodes of arterial or venous thrombosis (28.6% vs. 84.6%) and a higher incidence of thrombocytopenia (85.7% vs. 54.9%), respectively. Low complement and elevated high-sensitivity CRP levels were observed more frequently in the microvascular group compared with the non-microvascular group (complement 38.1% vs. 18.7%; high-sensitivity CRP 71.4% vs. 31.9%, respectively). Anti-β2-glycoprotein I antibodies were more prevalent in patients with microvascular involvement than in patients without (66.7% vs. 33.0%, respectively). Multivariate logistic regression analysis revealed that thrombocytopenia (odds ratio = 4.523, 95% confidence interval 1.139-17.962), elevated high-sensitivity CRP levels (odds ratio = 6.385, 95% confidence interval 1.969-20.704), and anti-β2-glycoprotein I antibody positivity (odds ratio = 5.042, 95% confidence interval 1.555-16.352) were independent risk factors for microvascular involvement. A Kaplan-Meier analysis revealed that survival was significantly poorer in patients with microvascular involvement compared with patients without (p = 0.0278). CONCLUSIONS In addition to arterial and venous thrombosis, antiphospholipid syndrome can affect the microvasculature of select organs. It is thus important for clinicians to be aware that antiphospholipid syndrome-associated microvascular involvement has a unique pathogenesis and can be a life-threatening condition.

Abstract
OBJECTIVE To observe the morphological changes in the testes and ovaries of adult 12th-generation Oncomelania hupensis bred for 12 winters in Weishan Lake areas. METHODS The offspring of the adult O. hupensis snails bred in the Weishan Lake that were originated from the Yangzhou section of the Yangtze River was defined as the experiment group, while uninfected, adult O. hupensis snails captured from the marshland of the Yangzhou section of the Yangtze River served as the control group. Snails were dissected and intact testicular and ovarian specimens were sampled, routinely fixed, dehydrated, embedded, polymerized in an oven and sliced on an ultramicrotome. The sections were visualized under a transmission electron microscope, and the ultrastructure of the snail gonad was compared between the experiment and control groups. RESULTS Transmission electron microscopy showed "9 + 2" microtubules on the transverse sections of the tails of sperm cells in the testes of male snails in the control group, with triangular acrosomes and spiral, dense nuclei seen in the tip, while in the experiment group, the "9 + 2" microtubules disappeared on the transverse sections of the tails of sperm cells in the testes of male snails, with low chromatin density found in the tip. Transmission electron microscopy revealed clear nucleolus and nuclear membranes in the ova of female snail ovaries, and displayed yolk body, liposomes and endoplasmic reticulum in the cytoplasm, bilayer twists of nuclear membrane and a uniform nucleolus in the control group, while in the experiment group, smooth nuclear membrane and unclear nucleolus were observed in the ova of female snail ovaries, with few contents seen within cells. CONCLUSIONS Following breeding for 12 winters in the Weishan Lake, the 12th-generation O. hupensis snails fail to fully adapt to the natural environment in northern China, and the remarkable changes in the ultrastructure of the snail gonad may be a cause of gradual decline and even extinction of O. hupensis in the Weishan Lake areas.

Abstract
We report the detection of endometrial and ovarian cancers based on genetic analyses of DNA recovered from the fluids obtained during a routine Papanicolaou (Pap) test. The new test, called PapSEEK, incorporates assays for mutations in 18 genes as well as an assay for aneuploidy. In Pap brush samples from 382 endometrial cancer patients, 81% [95% confidence interval (CI), 77 to 85%] were positive, including 78% of patients with early-stage disease. The sensitivity in 245 ovarian cancer patients was 33% (95% CI, 27 to 39%), including 34% of patients with early-stage disease. In contrast, only 1.4% of 714 women without cancer had positive Pap brush samples (specificity, ~99%). Next, we showed that intrauterine sampling with a Tao brush increased the detection of malignancy over endocervical sampling with a Pap brush: 93% of 123 (95% CI, 87 to 97%) patients with endometrial cancer and 45% of 51 (95% CI, 31 to 60%) patients with ovarian cancer were positive, whereas none of the samples from 125 women without cancer were positive (specificity, 100%). Finally, in 83 ovarian cancer patients in whom plasma was available, circulating tumor DNA was found in 43% of patients (95% CI, 33 to 55%). When plasma and Pap brush samples were both tested, the sensitivity for ovarian cancer increased to 63% (95% CI, 51 to 73%). These results demonstrate the potential of mutation-based diagnostics to detect gynecologic cancers at a stage when they are more likely to be curable.

Abstract
Head smut, caused by the fungus Sporisorium reilianum, is a devastating global disease of maize (Zea mays). In the present study, maize seedlings were artificially inoculated with compatible mating-type strains of S. reilianum by needle inoculation of mesocotyls (NIM) or by soaking inoculation of radicles (SIR). After NIM or SIR, Huangzao4 mesocotyls exhibited severe damage with brownish discoloration and necrosis, whereas Mo17 mesocotyls exhibited few lesions. Fluorescence and electron microscopy showed that S. reilianum infected maize within 0.5 day after SIR and mainly colonized the phloem. With longer incubation, the density of S. reilianum hyphae increased in the vascular bundles, concentrated mainly in the phloem. In Mo17, infected cells exhibited apoptosis-like features, and hyphae became sequestered within dead cells. In contrast, in Huangzao4, pathogen invasion resulted in autophagy that failed to prevent hyphal spreading. The growth of S. reilianum hyphae diminished at 6 days after inoculation when expression of the R genes ZmWAK and ZmNL peaked. Thus, 6 days after SIR inoculation might be an important time for inhibiting the progress of S. reilianum infection in maize. The results of this study will provide a basis for further analysis of the mechanisms of maize resistance to S. reilianum.

Abstract
The sympathetic nervous system drives brown and beige adipocyte thermogenesis through the release of noradrenaline from local axons. However, the molecular basis of higher levels of sympathetic innervation of thermogenic fat, compared to white fat, has remained unknown. Here we show that thermogenic adipocytes express a previously unknown, mammal-specific protein of the endoplasmic reticulum that we term calsyntenin 3β. Genetic loss or gain of expression of calsyntenin 3β in adipocytes reduces or enhances functional sympathetic innervation, respectively, in adipose tissue. Ablation of calsyntenin 3β predisposes mice on a high-fat diet to obesity. Mechanistically, calsyntenin 3β promotes endoplasmic-reticulum localization and secretion of S100b-a protein that lacks a signal peptide-from brown adipocytes. S100b stimulates neurite outgrowth from sympathetic neurons in vitro. A deficiency of S100b phenocopies deficiency of calsyntenin 3β, and forced expression of S100b in brown adipocytes rescues the defective sympathetic innervation that is caused by ablation of calsyntenin 3β. Our data reveal a mammal-specific mechanism of communication between thermogenic adipocytes and sympathetic neurons.

Abstract
OBJECTIVE The objective of this paper is to assess the role of gender on survival rate and causes of death and organ damage in systemic lupus erythematosus (SLE) patients in China from 2009 to 2015. METHODS We conducted a multicenter cohort study to analyze the differences in outcome data between male and female SLE patients. A group of 1494 SLE patients who fulfilled the 1997 American College of Rheumatology SLE classification criteria were enrolled in the Chinese Systemic Lupus Erythematosus Treatment and Research Group (CSTAR) registry from April 2009 to February 2010. All enrolled patients were followed up at least once per year from 2009 to 2015. For patients who could not attend the outpatient clinic, follow-up was conducted by telephone interview. We collected demographic data, clinical manifestations and damage scores (System Lupus International Collaborating Clinics/American College of Rheumatology Damage Index (SDI)). Survival rates were evaluated using the Kaplan-Meier method. RESULTS This study included 1352 women and 142 men. The five-year survival rates were 92.0% for men and 97.6% for women. The survival rates of males were significant lower than for females ( p = 0.019). Male patients received methylprednisolone pulse therapy and cyclophosphamide significantly more than female patients ( p = 0.010). During follow-up, 12 male patients and 66 female patients died. The most common cause of death was infection (41.7%) for men and active SLE disease (27.3%) for women. At the end of the study, the major accumulated organ damages included renal (8.5%) and musculoskeletal (7.7%), and nervous system (5.6%) for men and renal (8.8%) and musculoskeletal (6.7%) for women. There were no significant differences in SDI scores between the two groups at baseline and at the end of the study. CONCLUSIONS Male SLE patients had lower survival rates than female patients. Male patients received more methylprednisolone pulse and cyclophosphamide therapy. The most common causes of death were infection for male patients and active SLE disease for female patients. The major accumulated organ damages were renal, musculoskeletal, and nervous system both for male and female SLE patients in China.

Abstract
Electrostatic charges of granular materials always generate under a strong electric field for both nature and industry. To understand the impact charging of a single particle in such situations is therefore essential. However, the traditional Faraday cup approach has difficulty in determining the impact charge with the electric field. Here, we develop Millikan's method to measure the transferred charge of individual particle collision. The target plate lies beneath the vertical electrodes, and a high-speed camera records the particle movement. The single particle passes through the uniform electric field before and after colliding with the target. We can calculate the impact charge of the particle according to its initial charge and final charge, as well as the impact speed and impact angle. In addition, the electric field strength on the particle above the impact point is determined with the finite element method. The immunity to electric field influence on charge measurement and the ability to obtain relevant parameters make this a powerful tool to characterize charging processes under the electric field.

Abstract
Immunological methods, which have been widely used in autoimmune blistering diseases (AIBDs) of the oral mucosa, can also be adopted as auxiliary diagnostic tools in oral lichen planus (OLP) and discoid lupus erythematosus (DLE). AIBDs, characterized by autoantibodies against structural proteins of keratinocytes or the basement membrane zone, clinically present as blisters and erosions of the oral mucosa. When atypical lesions occur, OLP or DLE may be confused with AIBDs. The improvement of diagnostic accuracy is necessary due to the significant differences in treatment and prognosis among these diseases. A variety of immunological methods are used for qualitative and quantitative detection of target antigens and autoantibodies. These methods can evaluate efficacy of treatment, monitor diseases and guide treatment decisions. In this review, we discuss the application of immunofluorescence, biochemical tests, and protein microarrays for AIBDs, OLP and DLE, as well as the differential diagnostic methods using immunological tests.

Abstract
Dyskeratosis congenita (DC) is a rare disease and a genetic heterogeneity of bone marrow failure, characterized by muco-cutaneous triad of mucosal leukoplakia, abnormal skin pigmentation, nails dystrophy and often involving multiple organs or systems. The inheritance patterns of DC include X-linked recessive, autosomal dominant and recessive patterns. However, the inheritance patterns in 30%-40% of DC patients remained unknown. Dyskeratosis congenita is difficult to diagnose because of its genetic and clinical heterogeneity. This article will review and discuss the state-of-the-art progresses in genetics, clinical manifestation, diagnosis, differential diagnosis, treatment and prognosis of DC.

Abstract
Abstract
The increasing incidence of obesity and its co-morbid conditions poses a great challenge to global health. It is becoming clear that obesity is associated not only with type 2 diabetes mellitus and cardiovascular disease, but also with multiple types of cancer. Obesity and its associated inflammatory response has been closely linked to many aspects of cancer biology, including tumorigenesis, cancer immunotherapy and cancer cachexia. Obesity is caused by energy surplus when energy intake exceeds energy expenditure. As an important contributor of total energy expenditure is adaptive thermogenesis in brown adipose tissue, a promising and emerging avenue for obesity treatment is to increase energy expenditure by augmenting the activity of thermogenic adipocytes. Emerging evidence indicates that the immune system is instrumental in the control of host energy metabolism. However, the underlying mechanism has not been fully understood; specifically, the role of T-cells in regulating host thermogenesis has not been well studied. Here we identified that gamma delta T-cells and their associated signaling play a critical role in mediating adaptive thermogenesis in response to cold exposure in brown adipose tissue and high-fat-diet-induced obesity. In pursuing these studies we hope to discover new ways (targeting immune cells) to support the obesity treatment and reduce obesity-associated systemic inflammation and complications, especially cancer.

Abstract
Lower respiratory tract infections (LRTIs) are a substantial public health problem and a leading cause of significant morbidity and mortality worldwide. The aim of this study was to evaluate a commercially available loop-mediated isothermal amplification (LAMP) assay for the simultaneously detection of thirteen common lower respiratory pathogens in patients with respiratory symptoms. All participants age from 1 to 101 years old were recruited from inpatient or outpatient of Meizhou People's Hospital between October 2016 and March 2018. A total of 1767 sputum samples and 88 bronchoalveolar lavage fluid samples from patients with suspected LRTI were collected. For each sample, a parallel study using both routine bacterial culture-based and LAMP assays were carried out. In total, 810 (44.85%) out of the 1855 samples were found to be positive infected with respiratory pathogens by using the LAMP assays. Methicillin-resistant Staphylococcus aureus (MecA) was the most predominant bacterial pathogens, with proportions of 17.09% in sputum and 10.23% bronchoalveolar lavage fluid samples, respectively. The proportions of bacterial pathogen infection with Streptococcus pneumoniae (Spn) (24.24%) was relatively high in aged <15 group (P <.001) while the proportions of bacterial pathogen infection with MecA (22.89%) was relatively high in aged >60 group (P <.001). Bacterial pathogen infection with MecA having the highest prevalence with proportions of 17.81% and 13.94% in male and female, respectively. A statistically higher proportion of male group had bacterial pathogen infection with Pseudomonas aeruginosa (Pae) in this study (P = .035). Comparison of results between the LAMP assay and culture method was conducted and our results indicated that there was higher detection rate by the LAMP assay than the bacterial culture method. Comparison of the results obtained with the LAMP assay and those obtained by sequencing analysis, when the sequencing method was set to 100%, demonstrating that the LAMP assay is 100% specific and 95.50% sensitive. The technique of LAMP assay was proved to be a simple, sensitive, specific, convenient, and rapid method, which can be implemented for diagnosing pathogenic bacteria in patients with LRTIs in primary labs without any need for expensive equipment or specialized techniques in resource-limited areas of China.
