Abstract
Objectives: Analyze the clinical characteristics of patients with primary antiphospholipid syndrome (PAPS) progressing to systemic lupus erythematosus (SLE).Explore the risk factors for the progression from PAPS to SLE. Methods: The clinical data of 262 patients with PAPS enrolled in Peking Union Medical College Hospital from February 2005 to September 2021 were evaluated. Assessments included demographic data, clinical manifestations, laboratory tests (serum levels of complement, anti-nuclear antibodies, anti-double-stranded DNA antibodies), treatment, and outcomes. Kaplan-Meier analysis was used to calculate the prevalence of SLE in patients with PAPS. Univariate Cox regression analysis was employed to identify the risk factors for PAPS progressing to SLE. Results: Among 262 patients with PAPS, 249 had PAPS (PAPS group) and 13 progressed to SLE (5.0%) (PAPS-SLE group). Univariate Cox regression analysis indicated that cardiac valve disease (HR=6.360), positive anti-double-stranded DNA antibodies (HR=7.203), low level of complement C3 (HR=25.715), and low level of complement C4 (HR=10.466) were risk factors for the progression of PAPS to SLE, whereas arterial thrombotic events (HR=0.109) were protective factors (P<0.05 for all). Kaplan-Meier analysis showed that the prevalence of SLE in patients suffering from PAPS with a disease course>10 years was 9%-15%. Hydroxychloroquine treatment had no effect on the occurrence of SLE in patients with PAPS (HR=0.753, 95%CI 0.231-2.450, P=0.638). Patients with≥2 risk factors had a significantly higher prevalence of SLE compared with those with no or one risk factor (13-year cumulative prevalence of SLE 48.7% vs. 0 vs. 6.2%, P<0.001 for both). Conclusions: PAPS may progress to SLE in some patients. Early onset, cardiac-valve disease, positive anti-dsDNA antibody, and low levels of complement are risk factors for the progression of PAPS to SLE (especially in patients with≥2 risk factors). Whether application of hydroxychloroquine can delay this transition has yet to be demonstrated.

Abstract
Soft tissue sarcoma (STS) is a group of rare malignant tumors originating from mesenchymal tissue, with a high degree of malignancy and a wide range of pathological subtypes. The prognosis varies among different subtypes, and treatment increasingly relies on selecting appropriate treatment methods for different subtypes. Surgical treatment is still the main treatment method at present, and the development of immune and targeted therapy also brings new hope for the treatment of soft tissue sarcoma. Immune checkpoint inhibitors, oncolytic viruses and T cell therapy have shown well safety and efficacy in clinical trials. Targeted drugs such as trabectedin and lenvatinib have changed the treatment pattern of soft tissue sarcoma. Currently, chemotherapy based on doxorubicin and ifosfamide is still the first line treatment for patients with advanced soft tissue sarcoma who have distant metastasis. However, the adverse reactions of doxorubicin limit its application in elderly patients, and trofosfamide has shown good efficacy and safety as an alternative in clinical trials. The efficacy of postoperative radiotherapy has been confirmed, which can reduce the local recurrence rate after surgical resection of soft tissue sarcoma. In summary, multimodal comprehensive treatment has become the main strategy for the treatment of soft tissue sarcoma. The combination of different treatment methods can generate synergistic effects and help patients obtain more clinical benefits, such as the combination of doxorubicin and immune checkpoint inhibitors, and the combination of antiangiogenic drugs and chemotherapy drugs. At the 2023 annual meeting of the American Society of Clinical Oncology (ASCO), oncologists from all over the world reported many researches related to the treatment of soft tissue sarcoma. This article aims to review the new progress in the treatment of soft tissue sarcoma in the 2023 annual meeting of ASCO.

Abstract
Yolk sac-derived microglia and peripheral monocyte-derived macrophages play a key role during Parkinson's disease (PD) progression. However, the regulatory mechanism of microglia/macrophage activation and function in PD pathogenesis remains unclear. Recombination signal-binding protein Jκ (RBP-J)-mediated Notch signaling regulates macrophage development and activation. In this study, with an 1-Methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) hydrochloride-induced acute murine PD model, we found that Notch signaling was activated in amoeboid microglia accompanied by a decrease in tyrosine hydroxylase (TH)-positive neurons. Furthermore, using myeloid-specific RBP-J knockout (RBP-JcKO) mice combined with a PD model, our results showed that myeloid-specific disruption of RBP-J alleviated dopaminergic neurodegeneration and improved locomotor activity. Fluorescence-activated cell sorting (FACS) analysis showed that the number of infiltrated inflammatory macrophages and activated major histocompatibility complex (MHC) II+ microglia decreased in RBP-JcKO mice compared with control mice. Moreover, to block monocyte recruitment by using chemokine (C-C motif) receptor 2 (CCR2) knockout mice, the effect of RBP-J deficiency on dopaminergic neurodegeneration was not affected, indicating that Notch signaling might regulate neuroinflammation independent of CCR2+ monocyte infiltration. Notably, when microglia were depleted with the PLX5622 formulated diet, we found that myeloid-specific RBP-J knockout resulted in more TH+ neurons and fewer activated microglia. Ex vitro experiments demonstrated that RBP-J deficiency in microglia might reduce inflammatory factor secretion, TH+ neuron apoptosis, and p65 nuclear translocation. Collectively, our study first revealed that RBP-J-mediated Notch signaling might participate in PD progression by mainly regulating microglia activation through nuclear factor kappa-B (NF-κB) signaling.

Abstract
The intracellular protozoan parasite Babesia gibsoni infects canine erythrocytes and causes babesiosis. The hazards to animal health have increased due to the rise of B. gibsoni infections and medication resistance. However, the lack of high-quality full-genome sequencing sets has expanded the obstacles to the development of pathogeneses, drugs, and vaccines. In this study, the whole genome of B. gibsoni was sequenced, assembled, and annotated. The genomic size of B. gibsoni was 7.94 Mbp in total. Four chromosomes with the size of 0.69 Mb, 2.10 Mb, 2.77 Mb, and 2.38 Mb, respectively, 1 apicoplast (28.4 Kb), and 1 mitochondrion (5.9 Kb) were confirmed. KEGG analysis revealed 2,641 putative proteins enriched on 316 pathways, and GO analysis showed 7,571 annotations of the nuclear genome in total. Synteny analysis showed a high correlation between B. gibsoni and B. bovis. A new divergent point of B. gibsoni occurred around 297.7 million years ago, which was earlier than that of B. bovis, B. ovata, and B. bigemina. Orthology analysis revealed 22 and 32 unique genes compared to several Babesia spp. and apicomplexan species. The metabolic pathways of B.gibsoni were characterized, pointing to a minimal size of the genome. A species-specific secretory protein SA1 and 19 homologous genes were identified. Selected specific proteins, including apetala 2 (AP2) factor, invasion-related proteins BgAMA-1 and BgRON2, and rhoptry function proteins BgWH_04g00700 were predicted, visualized, and modeled. Overall, whole-genome sequencing provided molecular-level support for the diagnosis, prevention, clinical treatment, and further research of B. gibsoni. IMPORTANCE The whole genome of B. gibsoni was first sequenced, annotated, and disclosed. The key part of genome composition, four chromosomes, was comparatively analyzed for the first time. A full-scale phylogeny evolution analysis based on the whole-genome-wide data of B. gibsoni was performed, and a new divergent point on the evolutionary path was revealed. In previous reports, molecular studies were often limited by incomplete genomic data, especially in key areas like life cycle regulation, metabolism, and host-pathogen interaction. With the whole-genome sequencing of B. gibsoni, we provide useful genetic data to encourage the exploration of new terrain and make it feasible to resolve the theoretical and practical problems of babesiosis.

Abstract
Objective: We sought to investigate the clinical characteristics and risk factors of antiphospholipid syndrome (APS) complicated by autoimmune hemolytic anemia (AIHA). Methods: Retrospective anaysis.Three hundred fifteen consecutive patients with APS were enrolled at the Department of Rheumatology of Peking Union Medical College Hospital between May 2017 to May 2021, and their clinical manifestations[including initial symptoms, time interval between APS onset and diagnosis, systemic lupus erythematosus(SLE), thrombotic events, obstetric morbidity, and extra-criteria manifestations] and laboratory test results[including blood routine, antiphospholipid antibodies(aPLs), blood lipid profile, homocysteine, anti-nuclear antibody profile, immunoglobulin levels, and complement levels] were collected. Then, univariate and multivariate logistic regression analyses were performed. Clinical features and risk factors were analyzed using univariable and multivariable logistic regression analysis. Results: Among 315 APS patients, 37 cases (11.7%) were complicated by AIHA, and AIHA was the first manifestation or co-occurrence. The median time interval between APS onset and diagnosis was 12 months. The proportion of SLE in APS patients combined with AIHA was higher than that in APS patients without AIHA[62.2%(23/37) vs. 19.4%(54/278), P<0.001]. There was no significant difference in the proportions of thrombosis and pregnancy morbidity between the two groups. In terms of extra-criteria manifestations, APS patients with AIHA had a significantly (P<0.05) greater risk of thrombocytopenia (OR=6.19, 95%CI 2.81-13.65) and higher proportions of hypocomplementemia, a positive lupus anticoagulant (LA) result, double aPLs positivity[i.e., any two of the following antibodies were positive: LA, anticardilolipin antibody(aCL), and anti-β2 glycoprotein Ⅰ(β2GPⅠ)], and triple aPLs positivity (i.e., LA, aCL, and anti-β2GPⅠ antibodies were all positive). Multivariate logistic regression analysis showed that SLE (OR=3.46,95%CI 1.60-7.48), thrombocytopenia (OR=2.56,95%CI 1.15-5.67), and hypocomplementemia (OR=4.29,95%CI 2.03-9.04) were independent risk factors for the complication of APS. In the primary APS subgroup, multivariate logistic regression analysis showed that livedo reticularis (OR=10.51,95%CI 1.06-103.78), thrombocytopenia (OR=3.77, 95%CI 1.23-11.57), and hypocomplementemia (OR=5.92,95%CI 1.95-17.95) were independent risk factors for the complication of APS. Conclusions: AIHA is not rare in APS patients; moreover, it occurs more frequently in APS secondary to SLE and is more likely to present with a variety of extra-criteria manifestations. Patients with AIHA should be promptly tested for antiphospholipid antibody profiles and alerted to the possibility of thrombotic events.

Abstract
Objectives: To examine the landscape and metastases of the lymph nodes in prostatic anterior fat pad (PAFP) at radical prostatectomy (RP), and to describe the clinical characteristic of the patients with lymph node metastases in PAFP. Methods: The clinical and pathological data of 287 prostate cancer patients underwent RP from December 2019 to August 2021 in Department of Urology, Sun Yat-sen University Cancer Center were collected and analyzed retrospectively. All patients were male, aging (66±7) years (range: 42 to 83 years). The preoperative prostate-specific antigen (PSA) (M(IQR)) were 16.00(29.64) μg/L (range: 0.01 to 99.90 μg/L). There were 244 patients with localized or locally advanced prostate cancer and 43 patients with metastatic prostate cancer. All PAFP were dissected at RP routinely and were sent for pathologic analysis respectively. The PAFP was dissected from the prostate apex caudally toward the bladder neck and dissection extended to the joint of the prostate and the endopelvic fascia bilaterally. All the specimen of PAFP were examined and reported by subspecialty pathologists of genitourinary tumors. Statistical analysis was performed by Student t test, Wilcoxon rank-sum test, χ2 test or Fisher exact test. Results: There were 8.0% (23/287) patients with lymph nodes in PAFP, 3.8% (11/287) patients with PAFP lymph node metastases. Pathologically upstaged occurred in 1 patient due to the PAFP lymph node as the solitary metastatic lesion. Patients with lymph node metastases in PAFP presented higher preoperative PSA (M(IQR): 48.2(73.0) μg/L vs. 15.4(26.5) μg/L, Z=3.158, P=0.002), clinical T stage and N stage (Z=2.977, P=0.003; Z=2.780, P=0.005) and preoperative Gleason score (Z=2.205, P=0.027). Conclusions: Routine dissection of PAFP at RP and separately pathological analysis may allow more lymph nodes and lymph node metastases detection. More accurate pathological N stage may be acquired and consequently may improve the survival of patients by offering more appropriate adjuvant or salvage therapy.

Abstract
The data of 33 patients with adult-onset still's disease (AOSD)-associated macrophage activation syndrome (MAS) were retrospectively collected from January 2013 to December 2020 in Peking Union Medical College Hospital. Hemophagocytic lymphohistiocytosis (HLH)-2004 criteria, macrophage activation syndrome/juvenile idiopathic arthritis (MS-Score) and hemophagocytic syndrome diagnostic score (HScore) were used to diagnose AOSD-associated MAS, respectively. The time of diagnosis of AOSD-associated MAS by MS-Score was 19.0 (4.5, 31.0) days [M (Q1,Q3)] earlier than by HLH-2004 criteria, and 13.5 (0.5, 21.5) days earlier than by HScore (both P<0.05). The difference was not statistically significant between the time of diagnosis of AOSD-associated MAS by Hscore and by HLH-2004 criteria (P>0.05). There was significant difference among the three criteria (P<0.001). MS-Score can be used to diagnose AOSD-associated MAS earlier than HLH-2004 criteria, while the timeliness of HScore is not certain.

Abstract
Objective: To evaluate the differences in clinical characteristics between different genders of Chinese patients with systemic sclerosis(SSc). Methods: The data of SSc patients registered in Chinese Rheumatism Data Center between August 2008 and June 2020 were retrospectively analyzed. Results: A total of 1 844 patients with SSc were enrolled in the study. The ratio of males to females was 289 to 1 555. The onset age was (48.6±13.7) years in males and (45.5±13.1) years in females(P<0.001). Male patients represented shorter disease duration [2.0(0.0, 4.0)years vs.3.0(1.0, 7.0) years, P<0.001],higher proportion of diffuse cutaneous SSc (dcSSc) [63.0% (182/289)vs.44.2%(688/1 555), P<0.001]. Although more man patients experienced smoking [47.4%(137/289) vs. 1.7%(27/1 555), P<0.001] and exposure to harmful environments [7.6%(22/289) vs. 2.1%(33/1 555), P<0.001], there was no statistically significant difference in interstitial lung disease between male and female patients [69.3%(181/261) vs. 74.5%(1 085/1 457), P=0.084].Otherwise, Raynaud's phenomenon [87.7% (1 364/1 555) vs.75.4%(218/289), P<0.001], arthritis [11.1%(173/1 555) vs.6.9%(20/289), P=0.032], gastroesophageal reflux disease [22.0%(342/ 1 555) vs.13.1%(38/289), P=0.001], and leucopoenia [10.7(161/1 511)% vs. 6.1%(17/279), P=0.019] were more common in female patients, but finger ulcer was less common [22.5%(350/1 555) vs. 30.4%(88/289), P=0.004]. Antinuclear antibody(ANA) positivity rate [85.6%(1 310/1 531) vs. 78.6%(221/281), P=0.003], anti-RNP antibody positivity rate [23.1%(342/1 479) vs.14.0%(38/271), P=0.001], anti-SSA antibody positivity rate [28.2%(419/1 487) vs.13.9%(38/274), P<0.001] were higher in female patients. Physician's global assessment(PGA) scores [1.4 (1.0, 2.0) vs. 1.0 (0.3, 1.6), P<0.001] and modified Rodnan Skin Score(mRSS) [18.0 (9.5, 28.0) vs. 14.0 (5.0, 28.0), P=0.003] were higher in males. Conclusion: Even though male SSc patients account for a small proportion, more extensive skin involvement, finger ulcers and higher PGA are manifested in males. Physicians need pay attention to these clinical disparities between different genders in SSc.

Abstract
OBJECTIVE To investigate the prevalence and genetic variation of Theileria in yellow cattle in Xiangxi Autonomous Prefecture of Hunan Province. METHODS A total of 184 blood specimens were collected from Fenghuang, Huanyuan and Baojing counties of Xiangxi Autonomous Prefecture during the period from August 2018 through August 2019, and were detect using PCR assay with the specific 18S ribosomal rRNA (18S rRNA) gene targeting Theileria. The gene sequences of positive specimens were aligned with the sequences recorded in GenBank, and a phylogenetic tree was created with Plasmodium ovale 18S rRNA as an outgroup. RESULTS A total of 143 blood samples were positive for Theileria, with a mean detection rate of 77.7%. Theileria was prevalent in the blood samples from yellow cattle in all three counties, with detection rates of 85.0% in Fenghuang County, 88.3% in Huayuan County and 61.0% in Baojing County, respectively. There was no significant difference in the detection rate of Theileria between Xiangxi yellow cattle and normal yellow cattle (77.2% vs. 79.5%; χ2 = 0.08, P > 0.05), while the detection of Theileria was significantly lower in the housed yellow cattle than in free-range cattle (68.9% vs. 89.7%; χ2 = 22.36, P < 0.01). A total of 18 PCR positive samples were randomly selected for sequencing and analysis, and all samples showed more than 99.0% homology with T. luwenshuni isolates. Phylogenetic analysis showed that the 18 positive samples were clustered into the same branch with T. luwenshuni, but were far away from other isolates. CONCLUSIONS The prevalence of Theileria is high in yellow cattle from Xiangxi Autonomous Prefecture of Hunan Province, and T. luwenshuni may be the dominant parasite species.

Abstract
A 43-year-old female patient was admitted with recurrent thrombosis for more than 2 years and thrombocytopenia for more than 1 year. Both arterial and venous thromboses developed especially at rare sites even during anticoagulation therapy such as cerebral venous sinus thrombosis. Antinuclear antibody, anti-ENA antibody and antiphospholipid antibody were all negative. Platelet count elevated to normal after high dose glucocorticoid and intravenous immunoglobulin (IVIG). Immune thrombocytopenia was suspected. When 4 grade thrombocytopenia recurred, intravenous heparin, rituximab 600 mg, IVIG and eltrombopag were administrated. After 3 weeks, thrombocytopenia did not improve, and new thrombosis developed instead. Screening of thrombophilia related genes revealed PROS1 gene heterozygous mutation and MTHFR TT genotype. Low amount of serum IgG κ monoclonal protein was detected. Heparin-induced thrombocytopenia was differentiated and excluded. Finally, serum negative antiphospholipid syndrome was considered the most likely diagnosis. Dexamethasone 20 mg/day × 4 days combined with sirolimus 2 mg/day was prescribed. The patient was discharged with low molecular weight heparin. At one month, her headache was greatly relieved. The platelet count raised to 20-30×109/L, and no new thrombosis or bleeding was reported.

Abstract
A 25-year-old woman was admitted to Peking Union Medical Hospital presented with arthralgia for 5 years, amenorrhea for 16 months, and speech disorder for 3 months. This patient has been afflicted by intermittent pain in metacarpophalangeal and proximal interphalangeal joints of both hands for 5 years. Her menstruation has been irregular 1 year ago and rapidly progressed to amenorrhea. Laboratory tests revealed postmenopausal sex hormones levels (estradiol<5 ng/L, follicle-stimulating hormone 62.5 IU/L, luteinizing hormone 58.71 IU/L) and no antral follicles were seen in gynecologic ultrasound. She was diagnosed with premature ovarian failure and treated with hormone replacement therapy, still with no ovulation. Numbness and weakness of right arm has recurrently occurred to her 4 months ago, and persistent weakness of right limbs combined with motor speech disorder occurred 1 month later. Magnetic resonance angiography was suggestive of ischemic stroke. Hormone replacement therapy was discontinued. Comprehensive laboratory tests revealed positive anti-dsDNA, anti-SSA/SSB, anticardiolipin and anti-β2GPⅠ antibodies. Systemic lupus erythematosus (SLE), antiphospholipid syndrome (APS) was diagnosed. Since no drug with gonadal toxicity had been applied to the patient before, her amenorrhea was considered to be due to autoimmune oophoritis secondary to SLE. After treated with high-dose glucocorticoid, mycophenolate mofetil and hydroxychloroquine for 4 months, her menstruation recurred and regularly occurred till now. In some cases, amenorrhea in SLE patient might be resulted from autoimmune oophoritis associated with lupus flare, instead of use of drug with gonadal toxicity.

Abstract
Objective: To examine the prevalence of multiple antiphospholipid antibodies (aPL) subtypes in healthy people and antiphospholipid syndrome (APS) patients, and to assess the value of IgA-aPL in the diagnosis of APS. Methods: According to the 2006 Sydney International APS Classification Criteria, a total of 218 APS patients who were admitted to Peking Union Medical College Hospital or West China Hospital of Sichuan University from July to December 2019 were enrolled. Among them, 66 were males, and 152 were females, aged (44.5±15.4) years, including 148 primary APS patients and 70 secondary APS patients. Age-and gender-matched controls were collected at the same period at the ratio of 1∶1 with the APS cases. IgA/IgG/IgM anticardiolipin antibodies (aCL) and anti-β2 glycoprotein I antibodies (aβ2GPI) were detected by chemiluminescent immunoassay. The differences of indicators between groups were analyzed, and the receiver operating characteristic (ROC) curve was used to evaluate the diagnostic value of IgA-aPL for APS. Results: The positivity of IgA-aCL and IgA-aβ2GPI was 20.6% and 15.6% in the APS patients, while in the IgG/IgM-aCL or IgG/IgM-aβ2GPI negative individuals, the isolated positivity of IgA-aCL and IgA-aβ2GPI was only 2.3% and 0.9%, respectively. Accordingly, IgA-aCL and IgA-aβ2GPI isolated positivity could be used to diagnose APS (P=0.216, 1, respectively). The area under the ROC curve (AUC) of IgG/IgM-aCL for APS diagnosis was 0.833, which was significantly better than that of IgG-aCL alone (AUC=0.776, P<0.001); while the AUC of IgA/IgG/IgM-aCL was 0.833, which could not further increase the diagnostic value for APS (P=0.287). As for aβ2GPI, the diagnostic efficacy of combined IgG/IgM (AUC=0.875) or IgA/IgG/IgM (AUC=0.875) antibodies was not superior to IgG-aβ2GPI used alone (AUC=0.869, both P>0.05). Besides, patients with IgA-aPL were more likely to have heart valve lesions and thrombocytopenia (both P<0.05). Conclusion: Based on the existing serological markers, such as lupus anticoagulant, IgG/IgM subtype of aCL and aβ2GPI, testing IgA-aCL and IgA-aβ2GPI cannot further improve the predictive value of APS. However, IgA-aPL is associated with clinical manifestations of APS, including heart valve lesions and thrombocytopenia.

Abstract
Inflammatory bowel disease (IBD) is characterized by chronic and relapsing intestinal inflammation, which currently lacks safe and effective medicine. Some previous studies indicated that Astragaloside IV (AS-IV), a natural saponin extracted from the traditional Chinese medicine herb Ligusticum chuanxiong, alleviates the experimental colitis symptoms in vitro and in vivo. However, the mechanism of AS-IV on IBD remains unclear. Accumulating evidence suggests that M2-polarized intestinal macrophages play a pivotal role in IBD progression. Here, we found that AS-IV attenuated clinical activity of DSS-induced colitis that mimics human IBD and resulted in the phenotypic transition of macrophages from immature pro-inflammatory macrophages to mature pro-resolving macrophages. In vitro, the phenotype changes of macrophages were observed by qRT-PCR after bone marrow-derived macrophages (BMDMs) were induced to M1/M2 and incubated with AS-IV, respectively. In addition, AS-IV was effective in inhibiting pro-inflammatory macrophages and promoting the pro-resolving macrophages to ameliorate experimental colitis via the regulation of the STAT signaling pathway. Hence, we propose that AS-IV can ameliorate experimental colitis partially by modulating macrophage phenotype by remodeling the STAT signaling, which seems to have an essential function in the ability of AS-IV to alleviate the pathological progress of IBD.

Abstract
Objective: To study clinical characteristics and pregnancy outcomes under anti-coagulation therapy of non-criteria obstetric antiphospholipid syndrome. Methods: Patients suspected of obstetric antiphospholipid syndrome(OAPS) were recruited through Chinese Rheumatism Data Center from 2015 to 2019 consecutively. Patients fulfilling 2006 Sydney revised antiphospholipid syndrome criteria were classified as OAPS. Patients fulfilling definition of non-criteria OAPS(NCOAPS) by expert consensus on diagnosis and management of obstetric antiphospholipid syndrome of China were classified as NCOAPS. Clinical characteristics and laboratory results of two groups were compared. Live birth rates and pregnancy outcomes under anti-coagulation therapy were studied. Results: A total of 88 patients were enrolled, including 56 patients (63.6%) as OAPS, 32(36.4%) as NCOAPS. Live births were only reached in 16.1% (9/56) in OAPS patients and 12.5%(4/32) in NCOAPS. Fetal losses after 10 weeks of gestation and pre-eclampsia before 34 weeks were more common in OAPS group compared to NCOAPS group [78.6%(44/56) vs. 18.8%(6/32), P<0.001; 25.0%(14/56) vs. 3.1%(1/32), P=0.020, respectively]. After enrollment, 15 pregnancies were recorded in OAPS, 10 in NCOAPS, all of whom were treated with low-dose aspirin (LDA) combined with low-molecular weight heparin (LMWH). Live birth rates saw dramatic improvements compared to baseline levels in OAPS [16.1% (9/56) vs. 11/15] along with NCOAPS [12.5% (4/32) vs. 7/10]. Conclusion: Though NCOAPS and OAPS patients differ in antiphospholipid antibody spectrum and pattern of pregnancy morbidities, both groups benefit from LDA combined with LWMH treatment, as live birth rates improve. Non-criteria OAPS patients are recommended to receive anti-coagulation therapy during pregnancy.

Abstract
Rationale: The malignant phenotypes of glioblastomas (GBMs) are primarily attributed to glioma stem cells (GSCs). Our previous study and other reports have suggested that both miR-139 and its host gene PDE2A are putative antitumor genes in various cancers. The aim of this study was to investigate the roles and mechanisms of miR-139/PDE2A in GSC modulation. Methods: Clinical samples were used to determine miR-139/PDE2A expression. Patient-derived glioma stem-like cells (PD-GSCs) were stimulated for immunofluorescent staining, sphere formation assays and orthotopic GBM xenograft models. Bioinformatic analysis and further in vitro experiments demonstrated the downstream molecular mechanisms of miR-139 and PDE2A. OX26/CTX-conjugated PEGylated liposome (OCP) was constructed to deliver miR-139 or PDE2A into glioma tissue specifically. Results: We demonstrated that miR-139 was concomitantly transcribed with its host gene PDE2A. Both PDE2A and miR-139 indicated better prognosis of gliomas and were inversely correlated with GSC stemness. PDE2A or miR-139 overexpression suppressed the stemness of PD-GSCs. FZD3 and β-catenin, which induced Wnt/β-catenin signaling activation, were identified as targets of miR-139 and mediated the effects of miR-139 on GSCs. Meanwhile, PDE2A suppressed Wnt/β-catenin signaling by inhibiting cAMP accumulation and GSK-3β phosphorylation, thereby modulating the self-renewal of PD-GSCs. Notably, Notch1, which is also a target of miR-139, suppressed PDE2A/miR-139 expression directly via downstream Hes1, indicating that miR-139 promoted its own expression by the miR-139-Notch1/Hes1 feedback circuit. Expectedly, targeted overexpression miR-139 or PDE2A in glioma with OCP system significantly repressed the stemness and decelerated glioma progression. Conclusions: Our findings elaborate on the inhibitory functions of PDE2A and miR-139 on GSC stemness and tumorigenesis, which may provide new prognostic markers and therapeutic targets for GBMs.

Abstract
Abstract
A series of novel biodegradable copolyesters named poly(butylene 3-methyl adipate co-terephthalate) (PBAmT) were synthesized from the monomers of 3-methyl adipic acid (AAm), 1,4-butanediol (BDO), and terephthalic acid (TPA) through a process of esterification and polycondensation. 1H NMR analysis shows that they are random copolymers whose composition can be well controlled by the feed ratio of monomers. From the results of DSC and XRD, the introduction of methyl group successfully destroys the crystallizability of the PBAm chains, thus making it become a relative soft segment compared to PBA, while these random PBAmT copolymers constructed by soft segment PBAm and rigid segment PBT change from semi-crystalline polymers to nearly amorphous polymers as the feed ratio of Am increases. Especially, mechanical tests reveal that the copolymers show outstanding elasticity and rebound resilience with excellent strength. These thermoplastic copolyester elastomers with good performance by simply introduction of branched methyl group on polybutylene adipate terephthalate (PBAT) copolymer chains may well explore the potential application of biodegradable PBAT-based material.

Abstract
PURPOSE To evaluate the prognostic significance of circulating tumour cell (CTC) number determined on the Epic Sciences platform in men with metastatic castration-resistant prostate cancer (mCRPC) treated with an androgen receptor signalling inhibitor (ARSI). PATIENTS AND METHODS A pre-treatment blood sample was collected from men with progressing mCRPC starting either abiraterone or enzalutamide as a first-, second- or third-line systemic therapy at Memorial Sloan Kettering Cancer Center (Discovery cohort, N = 171) or as a first- or second-line therapy as part of the multicenter PROPHECY trial (NCT02269982) (Validation cohort, N = 107). The measured CTC number was then associated with overall survival (OS) in the Discovery cohort, and progression-free survival (PFS) and OS in the Validation cohort. CTC enumeration was also performed on a concurrently obtained blood sample using the CellSearch® Circulating Tumor Cell Kit. RESULTS In the MSKCC Discovery cohort, CTC count was a statistically significant prognostic factor of OS as a dichotomous (<3 CTCs/mL versus ≥ 3 CTCs/mL; hazard ratio [HR] = 1.8 [95% confidence interval {CI} 1.3-3.0]) and a continuous variable when adjusting for line of therapy, presence of visceral metastases, prostate-specific antigen, lactate dehydrogenase and alkaline phosphatase. The findings were validated in an independent datas et from PROPHECY (HR [95% CI] = 1.8 [1.1-3.0] for OS and 1.7 [1.1-2.9] for PFS). A strong correlation was also observed between CTC counts determined in matched samples on the CellSearch® and Epic platforms (r = 0.84). CONCLUSION The findings validate the prognostic significance of pretreatment CTC number determined on the Epic Sciences platform for predicting OS in men with progressing mCRPC starting an ARSI.

Abstract
With the recognition of antineutrophil cytoplasmic antibodies (ANCA)-related vasculitis and widespread vaccination against viral hepatitis B, the prevalence of polyarteritis nodosa (PAN) varied considerably. In our study, patients diagnosed as polyarteritis nodasa (PAN)based on the 1990 American College of Rheumatology(ACR) criteria were reclassified using 2007 European Medicines Agency(EMA) algorithm modified by 2012 Chapel Hill Consensus Conference(CHCC) definitions, aiming to evaluate the new classification criteria for the diagnosis of PAN. A total of 113 PAN patients admitted to Peking Union Medical College Hospital from January 2002 to December 2018 were retrospectively analyzed, who were classified into three subtypes including 9 patients with cutaneous, 80 with classic and 24 Hepatitis B virus (HBV) associated PAN. All patients were reclassified according to 2007 EMA algorithm using CHCC 2012 definitions. As a result, 7 patients were diagnosed as microscopic polyangiitis(MPA) and 19 patients with unclassified vasculitis based on the new classification criteria. The diagnostic rate of PAN was gradually declined as the classification criteria of vasculitides was update. However, there are quite a few PAN patients in China, whom rheumatologists should pay attention to the early diagnosis and treatment.

Abstract
Objective: To compare the results of visual acuity testing for teenagers with visual acuity charts designed at 2.5-meter and 5-meter distances, and to investigate the accuracy of the 2.5-meter visual acuity chart. Methods: It was a self-control study. A total of 227 teenagers (454 eyes) with ametropia who came to the ophthalmic clinic of Peking Union Medical College Hospital from March 2019 to September 2019 were included. There were 123 males and 104 females aged (11.74±3.26) years. The vision examiners were trained in the same testing environment and passed the consistency test. Distance visual acuity of all participants was tested with charts designed at 2.5 meters and 5 meters in a 10-minute interval. According to the age (7-9, 10-12, 13-15 and 16-18 years old) and visual acuity (1.00-0.52, 0.40-0.30 and 0.22-0.10), the results of two kinds of visual acuity charts were compared. The testing order of the two visual charts was randomly determined. The visual acuity results were converted into logMAR values and compared. Paried t-student test was used to compare the difference between two charts, and Pearson correlation test was used to explore the correlation between the results of two charts. Results: The visual acuity of the right eye was 0.37±0.24 (logMAR) at 2.5 meters and 0.50±0.26 (logMAR) at 5 meters. The distance visual acuity measured with the 2.5-meter visual acuity chart was better (t=16.19, P<0.01). The visual acuity of the left eye was 0.36±0.23 (logMAR) at 2.5 meters and 0.45±0.23 (logMAR) at 5 meters (t=11.71, P<0.01). The differences between two charts were larger among teenagers with lower visual acuity (r=0.387,P<0.01). Conclusion: Under the same test conditions, the distance visual acuity measured with a 2.5-meter chart was significantly better than a 5-meter chart. The visual acuity chart designed at 2.5 meters was not an appropriate tool to measure distance vision in adolescents. (Chin J Ophthalmol, 2021, 57: 122-125).

Abstract
A 31-year-old woman was admitted to Peking Union Medical College Hospital presented with intermittent vomiting and abdominal pain for 2 years, and recurrence with paroxysmal dizziness for 1 month. This patient was diagnosed with systemic lupus erythematosus (SLE) 2 years ago with involvement of gastrointestinal and urinary tracts. One month ago, repeated vomiting and nausea recurred. No laboratory and imaging abnormalities were found in central nervous system and gastrointestinal evaluation. Orthostatic hypotension and fluctuation of blood pressure were recorded during hospitalization. Combined with sexual dysfunction, left adie pupil, anhidrosis and abnormal sympathetic skin response, autonomic nerve dysfunction related to SLE was diagnosed. After treated with pulse glucocorticoids and intravenous immunoglobulin, the patient's symptoms improved remarkably. Orthostatic hypotension in SLE patients may link to autonomic nerve dysfunction.

Abstract
Objective: To study the regulatory effects and mechanisms of deleted in lymphocytic leukemia 1 (DLEU1), microRNA-513a-5p (miR-513a-5p), and RAN binding protein 2 (RANBP2) in nephroblastoma. Methods: The GHINK-1 cells were transfected with pcDNA (pcDNA group), pcDNA-DLEU1 (pcDNA-DLEU1 group), miR-NC (miR-NC group), miR-513a-5p mimics (miR-513a-5p group), pcDNA-RANBP2 (pcDNA-RANBP2 group), pcDNA-DLEU1 and miR-NC (pcDNA-DLEU1+ miR-NC group), pcDNA-DLEU1 and miR-513a-5p mimics (pcDNA-DLEU1+ miR-513a-5p group), miR-513a-5p mimics and pcDNA (miR-513a-5p+ pcDNA group), miR-513a-5p mimics and pcDNA-RANBP2 (miR-513a-5p + pcDNA-RANBP2 group). Real-time quantitative reverse transcription polymerase chain reaction (RT-qPCR) was used to detect the expressions of DLEU1, miR-513a-5p, RANBP2 in nephroblastoma tissues, normal adjacent tissues, normal kidney cell HK2, and hemangioblastoma cell GHINK-1. Western blot was used to detect the expressions of proliferating cell nuclear antigen (PCNA), B cell lymphoma/leukemia-2 (Bcl-2) and Bcl-2 related X (Bax). Cell counting kit 8 (CCK-8) was used to detect the cell survival rate. Flow cytometry was used to detect the apoptosis rate. Dual luciferase report test was used to detect the luciferase activity of cells. Results: The expression levels of DLEU1, miR-513a-5p and RANBP2 in adjacent tissues were 1.02±0.08, 1.01±0.06, 1.00±0.05, respectively, significantly lower than 5.16±0.24, 0.23±0.02, 1.67±0.09 in nephroblasts tumor tissues (P<0.05). Their expression levels in HK2 cells were 1.00±0.06, 1.00±0.08, 1.02±0.09, respectively, significantly lower than 3.15±0.21, 0.18±0.01, 1.54±0.10 in GHINK-1 cells (P<0.05). Overexpression of DLEU1 significantly reduced the apoptosis rate (7.35±0.41 vs 12.35±1.12, P<0.05). Overexpression of RANBP2 significantly reduced the apoptosis rate (8.89±0.48 vs 12.64±1.12, P<0.05). Compared with the miR-NC group (1.01±0.06, 0.99±0.06), the luciferase activity of DLEU1-WT (0.43±0.04) and RANBP2-WT (0.61±0.07) in miR-513a-5p group were significantly reduced (P<0.05). Compared with anti-miR-NC group (0.99±0.07, 0.98±0.05), the luciferase activity of DLEU1-WT (1.34±0.11) and RANBP2-WT (1.39 ±0.13) in anti-miR-513a-5p group was significantly increased (P<0.05). Simultaneous overexpression of pcDNA-DLEU1 and miR-513a-5p in GHINK-1 cells significantly reduced the apoptosis rate (11.34±1.03 vs 8.51±0.69, P<0.05). Simultaneous overexpression of miR-513a-5p and RANBP2 in GHINK-1 cells significantly reduced the apoptosis rate (9.96±0.72 vs 15.94±1.00, P<0.05). Conclusions: The long-chain non-coding RNA (lncRNA) DLEU1 can promote the proliferation and inhibit the apoptosis of nephroblastoma cells. The mechanism is related to the targeted regulation of miR-513a-5p and RANBP2 function, which will provide theoretical support for the nephroblastoma treatment.

Abstract
Background Accumulating evidence has shown that tumor-associated macrophages (TAMs) play a critical role in tumor progression. Targeting TAMs is a potential strategy for tumor immunotherapy. However, the mechanism underlying the TAM phenotype and function needs to be resolved. Our previous studies have demonstrated that miR-125a can reverse the TAM phenotype toward antitumor. Meanwhile, we have found that miR-125a and miR-99b cluster in the first intron of the same host gene, and are transcribed simultaneously in bone marrow-derived macrophages (BMDMs) following LPS+IFNγ stimulation. However, it remains unclear whether miR-99b by itself can exert an antitumor effect by regulating macrophage phenotype. Methods miR-99b and/or miR-125a were delivered into TAMs of orthotopic hepatocellular carcinoma (HCC) or subcutaneous Lewis lung cancer (LLC) mice. The effect of treatment was evaluated by live imaging, TUNEL staining and survival tests. The phenotype of the immune cells was determined by qRT-PCR, ELISA, western blot and FACS. The capability of miR-99b-mediated macrophage phagocytosis and antigen presentation was detected by FACS and immunofluorescence staining. The underlying molecular mechanism was examined by qRT-PCR, reporter assay and western blot, and further verified in the tumor model. The expression of miR-99b and its target genes was determined in TAMs sorted from tumor and adjacent tissues in patients with liver cancer. Results Targeted delivery of miR-99b and/or miR-125a into TAMs significantly impeded the growth of HCC and LLC, especially after miR-99b delivery. More importantly, the delivery of miR-99b re-educated TAM toward antitumor phenotype with enhanced immune surveillance. Further investigation of mechanisms showed that macrophage-specific overexpression of miR-99b promoted M1 while suppressing M2 macrophage polarization by targeting κB-Ras2 and/or mTOR, respectively. miR-99b-overexpressed M1 macrophage was characterized by stronger capability of phagocytosis and antigen presentation. Additionally, delivery of simTOR or siκB-Ras2 into TAMs inhibited miR-99b antagomir-triggered tumor growth. Finally, miR-99b expression was lower in TAMs of patients with liver cancer than that in adjacent tissues, while the expression of κB-Ras2 and mTOR was reversed. Conclusions Our results reveal the mechanism of miR-99b-mediated TAM phenotype, indicating that TAM-targeted delivery of miR-99b is a potential strategy for cancer immunotherapy.

Abstract
Toxoplasma gondii, a ubiquitous pathogen that infects nearly all warm-blooded animals and humans, can cause severe complications to the infected people and animals as well as serious economic losses and social problems. Here, one local strain (TgPIG-WH1) was isolated from an aborted pig fetus, and the genotype of this strain was identified as ToxoDB #3 by the PCR RFLP typing method using 10 molecular markers (SAG1, SAG2, alternative SAG2, SAG3, BTUB, GRA6, L358, PK1, C22-8, C29-2 and Apico). A comparison of the virulence of this isolate with other strains in both mice and piglets showed that TgPIG-WH1 was less virulent than type 1 strain RH and type 2 strain ME49 in mice, and caused similar symptoms to those of ME49 such as fever in piglets. Additionally, in piglet infection with both strains, the TgPIG-WH1 caused a higher IgG response and more severe pathological damages than ME49. Furthermore, TgPIG-WH1 caused one death in the 5 infected piglets, whereas ME49 did not, suggesting the higher virulence of TgPIG-WH1 than ME49 during piglet infection. Experimental infections indicate that the virulence of TgPIG-WH1 relative to ME49 is weaker in mice, but higher in pigs. This is probably the first report regarding a ToxoDB #3 strain from pigs in Hubei, China. These data will facilitate the understanding of genetic diversity of Toxoplasma strains in China as well as the prevention and control of porcine toxoplasmosis in the local region.

Abstract
Human four-and-a-half LIM domains protein 1 (FHL1) is a member of the FHL protein family, which serves an important role in multiple cellular events by interacting with transcription factors using its cysteine-rich zinc finger motifs. A previous study indicated that FHL1 was downregulated in several types of human cancer and served a role as a tumor suppressive gene. The overexpression of FHL1 inhibited tumor cell proliferation. However, to the best of our knowledge, there is no evidence to confirm whether FHL1 affected glioma growth, and the molecular mechanisms through which FHL1 represses tumor development remain unclear. In the present study, the expression level of FHL1 was determined using immunohistochemical staining in 114 tumor specimens from patients with glioma. The results indicated that FHL1 expression was negatively associated with the pathological grade of gliomas. Furthermore, Kaplan-Meier survival curves demonstrated that the patients with an increased FHL1 expression exhibited a significantly longer survival time, suggesting that FHL1 may be a prognostic marker for glioma. The protein level of FHL1 was relatively increased in the U251 glioma cell line compared with that in the U87 cell line. Therefore, FHL1 was knocked down in U251 by siRNA and overexpressed in U87, and it was identified that FHL1 significantly decreased the activation of PI3K/AKT signaling by interacting with AKT. Further experiments verified that FHL1 inhibited the growth of gliomas in vivo by modulating PI3K/AKT signaling. In conclusion, the results of the present study demonstrated that FHL1 suppressed glioma development through PI3K/AKT signaling.

Abstract
The 21-year-old male patient was admitted to the Department of Rheumatology and Immunology at Peking Union Medical College Hospital with chief complaints of "skin rash for 1 year and edema for 2 months". He was diagnosed with systemic lupus erythematosus (SLE) with renal, cardiac and hematological involvement. Remission was not achieved after glucocorticoid pulse treatment. The patient experienced oliguria, malignant hypertension, accompanied by thrombocytopenia and low serum complements, and elevated lactate dehydrogenase and serum creatinine. Schistocytes were seen in the peripheral blood smear. Thrombotic microangiopathy (TMA) secondary to SLE was diagnosed. Though plasma exchange was partially effective, TMA could not be controlled yet. The activity of serum von Willebrand factor -cleaving protease (ADAMTS 13) was 100%, and ADAMTS 13 inhibitor was negative. Finally, remission of the disease was achieved after second glucocorticoid pulse therapy and rituximab treatment. At the 3-month follow-up, the patient's condition was stable with mild anemia and normal platelet count. Patients with TMA secondary to SLE are heterogenous, while normal ADAMT 13 activity indicates poor prognosis. Early and aggressive treatment is important for disease control, and plasma exchange is helpful as a supportive care.

Abstract
The cross-slot geometry plays an important role in the study of nonlinear effects of viscoelastic fluids. The flow of viscoelastic fluid in a micro cross-slot with a high channel aspect ratio (AR, the ratio of channel depth to width) can be divided into three types, which are symmetric flow, steady-state asymmetric flow and time-dependent flow under the inlet condition with a constant velocity. However, the flow pattern of a viscoelastic fluid in the cross-slot when a stimulation is applied at inlets has been rarely reported. In this paper, the response of cross-slot flow under an external sinusoidal stimulation is studied by numerical simulations of a two-dimensional model representing the geometry with a maximum limit of AR. For the cases under constant inlet velocity conditions, three different flow patterns occur successively with the increase of Weissenberg number (Wi). For the cases under sinusoidal varying inlet velocity conditions, when the stimulation frequency is far away from the natural frequency of a viscoelastic fluid, the frequency spectrum of velocity fluctuation field shows the characteristics of a fundamental frequency and several harmonics. However, the harmonic frequency disappears when the stimulation frequency is close to the natural frequency of the viscoelastic fluid. Besides, the flow pattern shows spatial symmetry and changes with time. In conclusion, the external stimulation has an effect on the flow pattern of viscoelastic fluid in the 2D micro cross-slot channel, and a resonance occurs when the stimulation frequency is close to the natural frequency of the fluid.

Abstract
BACKGROUND We established a multi-centre online registry for primary Sjögren's syndrome (pSS) in China, and compared Chinese patients with those from other countries. METHODS Data were from 87 rheumatology centres in 27 provinces. All 2986 patients had pSS according to the 2002 American-European Consensus Group or the 2016 American College of Rheumatology/European League Against Rheumatism. All centres used the same methods. Data on demographics, clinical parameters, laboratory results, disease activity and treatments were examined. RESULTS The female:male ratio was 22.9:1, and the mean age at onset was 46.31 years. A total of 332 (11.1%) patients had thyroid disease, including hyperthyroidism (1.2%), hypothyroidism (6.0%) and subacute thyroiditis (3.9%). Dry eye had a prevalence of 68.59% in Chinese patients, 93.7-96% in European patients and 97.3% in American patients. Dry mouth had a prevalence of 86.5% in Chinese patients, 93.2-96% in European patients and 97.9% in American patients. Fewer Chinese than European patients had arthritis (6.9% vs. 15-19.3%). ANA positivity was 90.7% in Chinese, 81.3% in European and 77.6% in American patients. Anti-SSA antibody positivity was 84.6% in Chinese, 71% in European and 68.2% in American patients. The most commonly used drugs in Chinese patients were hydroxychloroquine (n = 1818; 67.5%), glucocorticoids (n = 1720; 63.9%) and total glucosides of paeony (n = 1120; 41.7%). CONCLUSIONS This study provided information on the phenotypes of Chinese patients with pSS, and identified several differences with patients from other geographical regions.

Abstract
Piroplasmosis is a disease of domestic and wild animals caused by tick-borne protozoa of the genera Theileria and Babesia. Piroplasmosis leads to substantial economic losses in the livestock industry. This disease has been frequently reported in subtropical and tropical regions worldwide. However, information regarding the prevalence of piroplasma in ticks collected from dogs and cattle is lacking in most areas. To assess the potential threat of piroplasmosis in South China, 671 ticks were collected in Guangxi Province. Deoxyribonucleic acid (DNA) was extracted from these ticks to evaluate the presence of piroplasma through a reverse line blot (RLB) hybridization assay using the hypervariable V4 region of the piroplasmic 18S ribosomal ribonucleic acid (r)RNA genes as probes to detect Theileria and Babesia species. The RLB results indicated that 144/671 (21.46%) ticks were infected with piroplasma species belonging to the genera Theileria or Babesia. Theileria buffeli, Babesia vogeli, Theileria annulata, and Theileria luwenshuni were present in the ticks at frequencies of 60/671 (8.94%), 21/671 (3.13%), 6/671 (0.89%), and 6/671 (0.89%), respectively. Mixed infections with 2 or more piroplasma species were present in 8/671 (1.19%) tick samples. The hypervariable V4 region of the piroplasmic 18S rRNA genes from 6 tick DNA samples with single infections was cloned, sequenced, and aligned to related sequences from GenBank. The Theileria and Babesia sequences were analyzed separately. 18S rRNA gene fragment sequences of T. annulata and T. buffeli were compared with previously reported homologous sequences. All 3 B. vogeli sequences examined in this study were grouped into the same cluster and belonged to the same genotype. The present study provides important epidemiological information regarding piroplasmosis occurrence in China. The existence of tick-borne piroplasma likely leads to high infection risks among the local animals in the studied areas.

Abstract
Tumor-associated macrophages (TAM) play pivotal roles in tumor progression and metastasis, but the contribution and regulation of different macrophage populations remain unclear. Here we show that Notch signaling plays distinct roles in regulating different TAM subsets in hepatocellular carcinoma (HCC). Myeloid-specific NOTCH blockade by conditional disruption of recombination signal binding protein Jκ (RBPj cKO) significantly delayed the growth of subcutaneously inoculated Lewis lung carcinoma (LLC), but accelerated orthotopically inoculated hepatic Hepa1-6 tumors in mice. In contrast to subcutaneous LLC, RBPj cKO significantly increased the number of TAMs in hepatic Hepa1-6 tumors despite impeded differentiation of monocyte-derived TAMs (moTAM). The dominating TAMs in orthotopic HCC manifested properties of Kupffer cells (KC) and hence are tentatively named KC-like TAMs (kclTAM). The increased proliferation of RBPj cKO kclTAMs was maintained even in Ccr2 -/- mice, in which moTAMs were genetically blocked. NOTCH signaling blockade accelerated proliferation of kclTAMs via enhanced β-catenin-dependent WNT signaling, which also downregulated IL12 and upregulated IL10 expression by kclTAMs likely through c-MYC. In addition, myeloid-specific RBPj cKO facilitated hepatic metastasis of colorectal cancer but suppressed lung metastasis in mice, suggesting that the phenotype of RBPj cKO in promoting tumor growth was liver-specific. In patient-derived HCC biopsies, NOTCH signaling negatively correlated with WNT activation in CD68+ macrophages, which positively correlated with advanced HCC stages. Therefore, NOTCH blockade impedes the differentiation of moTAMs, but upregulates Wnt/β-catenin signaling to promote the proliferation and protumor cytokine production of kclTAMs, facilitating HCC progression and hepatic metastasis of colorectal cancer. SIGNIFICANCE: These findings highlight the role of NOTCH and WNT signaling in regulating TAMs in hepatocellular carcinoma.

Abstract
Objective: To summarize the neurological manifestations in patients with primary Sjögren's syndrome (pSS). Methods: A total of 68 patients were diagnosed as pSS in neurology department of Peking Union Medical College Hospital from March 2014 to February 2018, among whom sixteen cases were excluded due to modified final diagnoses of primary neurological diseases. Therefore 52 pSS patients with neurological involvement were enrolled and retrospectively analyzed. They were divided into two groups as extensive group in which both central and peripheral nervous system were involved, non-extensive group in which either central or peripheral nervous system was involved. Results: Neurological manifestations were presented as primary symptoms in 98.1%(51/52) patients, while 35 had neurological involvement as their only extraglandular manifestations. Thirteen cases were in extensive group. The other 39 in non-extensive group including 22 cases with only peripheral nervous system involved and 17 cases with only single central nervous system involved. Compared to non-extensive group, the proportion of woman patients [13/13 vs.71.8% (28/39), P=0.047], serum IgG level [17.73(11.11,22.41)g/L vs. 11.49(9.58,13.40)g/L, P=0.017] and positive rates of oligoclonal band (OB) in cerebral spinal fluid (CSF) [7/13 vs. 22.6%(7/31), P=0.042)] were significantly higher in extensive involvement group. Conclusions: Neurological manifestations in pSS patients could be extensive, both central and peripheral nervous system might be associated. Female patients, high serum IgG level and positive OB in CSF are risk factors of extensive neurological involvement, suggesting that the immune system may be generally over-stimulated.

Abstract
A 28-year-old woman with multiple abscesses for 2 month and fever for 1 month was admitted in Peking Union Medical College Hospital. The skin abscesses gradually developed at skull, face, abdominal wall and pelvis. Laboratory examinations related to inflammatory reactions were strongly high including erythrocyte sedimentation rate 99 mm/1 h,C-reactive protein160.28 mg/L and ferritin 1 584 μg/L. Multiple nodules and cavities were detected in lungs. And vesico-cervical fistula was found during exploratory laparotomy. The pathological tests of abdominal tissues demonstrated necrosis and granuloma. Evidence of infectious diseases was not definite. Positive anti-proteinase 3 (PR3) antibody confirmed the diagnosis of granulomatosis with polyangiitis. After treated with glucocorticoid and immunosuppressants, the patient's symptoms improved remarkably. This case suggested that systemic vasculitis should be considered as a differential diagnosis of multiple abscesses which are not explained by infections.

Abstract
A ferroelectric liquid crystal (FLC) cell with continuously alignment structure is realized by a polarization hologram method for fabricating a Pancharatnam-Berry (PB) lens, which is employed as a concave/convex lens. The PB phase can be maintained by the optical axis in-plane switching; meanwhile, its diffraction efficiency can be tuned in a certain range by electrically controlling azimuthal angle and optical biaxiality of the smectic helical structure realized by deformed helix ferroelectric liquid crystals. The measured diffraction efficiency of the fabricated device is up to 87% and the response time can be 300μs with a low electric voltage. The FLC PB lens can have potential applications in existing optical devices and the realization of FLC with continuous alignment structure can be further used for other LC-based optical devices.

Abstract
A method for detecting the organophosphorus pesticides residue and aflatoxins in China herbal tea has been developed by UPLC-MS/MS coupled with vortex-assisted dispersive liquid-liquid microextraction (DLLME). The extraction conditions for vortex-assisted DLLME extraction were optimized using single-factor experiments and response surface design. The optimum conditions for the experiment were the pH 5.1, 347 µL of chloroform (extraction solvent) and 1614 µL of acetonitrile (dispersive solvent). Under the optimum conditions, the targets were good linearity in the range of 0.1 µg/L⁻25 µg/L and the correlation coefficient above 0.9998. The mean recoveries of all analytes were in the ranged from 70.06%⁻115.65% with RSDs below 8.54%. The detection limits were in the range of 0.001 µg/L⁻0.01µg/L. The proposed method is a fast and effective sample preparation with good enrichment and extraction efficiency, which can simultaneously detect pesticides and aflatoxins in China herbal tea.

Abstract
Objective: To analyze the clinical characteristics of antiphospholipid syndrome (APS) patients with chronic thromboembolic pulmonary hypertension (CTEPH). Methods: A total of 22 APS patients with CTEPH were enrolled in our study, who were admitted in Peking Union Medical College Hospital from January 2012 to August 2018. Diagnoses were confirmed by computed tomographic pulmonary angiography (CTPA), or pulmonary angiography. Demographic characteristics, clinical manifestations, laboratory tests, therapy, World Health Organization (WHO) functional class were retrospectively collected. Results: There were 15 females and 7 males with a median age of 29-year-old. Chest pain (6 cases), dyspnea on exertion (22 cases), cough (6 cases) and hemoptysis (9 cases) were the most common clinical manifestations. Lupus anticoagulant (LA), anticardiolipin (ACL) antibodies and anti-beta 2 glycoprotein Ⅰ (anti-β(2) GPⅠ) antibodies were all positive in 12 patients, two of three antibodies positive in 5 patients, only one positive in 5 patients. The WHO functional classes were Ⅱ-Ⅳ before treatment. Anticoagulants were administrated in all patients. After multidisciplinary evaluation, 9 patients underwent pulmonary thromboendarterectomy (PTE), who all had a good outcome. Symptoms in eleven over thirteen patients with only anticoagulants improved. Three patients developed cardiac deterioration while other 3 patients died of right heart failure during follow-up. Conclusion: Pulmonary embolism is one of the most common thrombotic events in APS patients. It is important to recognize symptoms and signs related to pulmonary embolism and start anticoagulation as soon as possible. Standard anticoagulation improves symptoms but can't reverse the process of pulmonary hypertension. Some patients may benefit from PTE after anticoagulation and multidisciplinary evaluation.

Abstract
It is essential to diagnose and assess children's ametropia after cycloplegic refraction. The use of cyclopentolate 1% eyedrops in children is safe and effective for cycloplegic refraction. An accurate prescription should be based on the actual eye position and accommodation, as well as cycloplegic refraction in children. (Chin J Ophthalmol, 2019, 55: 86-88).

Abstract
Ophthalmology is a discipline that is highly dependent on the development of technology. Artificial intelligence is a new technological revolution, which will in all-round and fundamentally influence the progression of modern ophthalmology. Ophthalmologists should actively pay close attention to the development of artificial intelligence technology with great enthusiasm, and gradually realize the maximum utilization of artificial intelligence technology so as to facilitate the new development in ophthalmology. We should proactively seek for the opportunities of cooperating with the research organization and expert engineers in the area of artificial intelligence to promote the application of artificial intelligence in ophthalmology as soon as possible. Ophthalmology is likely to be radically changed by artificial intelligence technology. (Chin J Ophthalmol, 2018, 54: 645-648).

Abstract
Objective: To evaluate the accuracy of contrast-enhanced ultrasound(CEUS) scanning in identifying vulnerable plaque in carotid artery. Methods: The study included a total of 25 patients who suffered from carotid artery stenosis and underwent carotid endarterectomy from January 2016 to December 2017 in Beijing Tsinghua Changgung Hospital, School of Clinical Medicine, Tsinghua University. Preoperative carotid artery contrast enhanced ultrasound and High-resolution MRI were performed to all patients to determine whether the plaques were stable. All patients then underwent carotid endarterectomy, during which, plaques were completely removed. Biopsies were performed using HE staining and CD31, CD34 and SMA immunohistochemistry was used to identify the plaques properties, including the thickness and integrity of the fiber cap, neovascular endothelium, hemorrhage, and inflammatory cells in the removed plaques.The results of these tests were compared with the diagnosis through the pre-operative imaging. Results: Among twenty-five cases, the pre-operative CEUS revealed sixteen with unstable plaques and nine with stable plaques. Meanwhile the post-operation pathology confirmed seventeen cases with unstable plaque components. The sensitivity of CEUS in the identification of carotid vulnerable plaque was 88.2%(15/17), the specificity was 87.5%(7/8), and the overall diagnostic accuracy was 88%(22/25). The sensitivity, specificity and overall diagnostic accuracy of high resolution MR for vulnerable plaque identification were 83.3%(10/12), 71.4%(5/7), 78.9%(15/19), respectively. There were no significant difference between two groups(χ(2)=0.003, P>0.05). Conclusions: The sensitivity, specificity and overall diagnostic accuracy of the CEUS for vulnerable plaque identification are high.Therefore, CEUS is recommended as one of the pre-operative diagnostic method for unstable plaque in carotid stenosis.

Abstract
The Notch pathway plays critical roles in the development and functional modulation of myeloid cells. Previous studies have demonstrated that Notch activation promotes M1 polarization and phagocytosis of macrophages; however, the downstream molecular mechanisms mediating Notch signal remain elusive. In an attempt to identify Notch downstream targets in bone marrow-derived macrophages (BMDMs) using mass spectrometry, the signal regulatory protein α (SIRPα) appeared to respond to knockout of recombination signal-binding protein Jk (RBP-J), the critical transcription factor of Notch pathway, in macrophages. In this study, we validated that Notch activation could repress SIRPα expression likely via the Hes family co-repressors. SIRPα promoted macrophage M2 polarization, which was dependent on the interaction with CD47 and mediated by intracellular signaling through SHP-1. We provided evidence that Notch signal regulated macrophage polarization at least partially through SIRPα. Interestingly, Notch signal regulated macrophage phagocytosis of tumor cells through SIRPα but in a SHP-1-independent way. To access the translational value of our findings, we expressed the extracellular domains of the mouse SIRPα (mSIRPαext) to block the interaction between CD47 and SIRPα. We demonstrated that the soluble mSIRPαext polypeptides could promote M1 polarization and increase phagocytosis of tumor cells by macrophages. Taken together, our results provided new insights into the molecular mechanisms of notch-mediated macrophage polarization and further validated SIRPα as a target for tumor therapy through modulating macrophage polarization and phagocytosis.

Abstract
Dehydroepiandrosterone (DHEA) possesses fat-reducing effect, while little information is available on whether DHEA regulates cell proliferation and mitochondrial function, which would, in turn, affect lipid droplet accumulation in the broiler. In the present study, the lipid droplet accumulation, cell proliferation, cell cycle and mitochondrial membrane potential were analysis in primary chicken hepatocytes after DHEA treated. The results showed that total area and counts of lipid droplets were significantly decreased in hepatocytes treated with DHEA. The cell viability was significantly increased, while cell proliferation was significantly inhibited in a dose dependent manner in primary chicken hepatocytes after DHEA treated. DHEA treatment significantly increased the cell population in S phase and decreased the population in G2/M in primary chicken hepatocytes. Meanwhile, the cyclin A and cyclin-dependent kinases 2 (CDK2) mRNA abundance were significantly decreased in hepatocytes after DHEA treated. No significant differences were observed in the number of mitochondria, while the mitochondrial membrane permeability and succinate dehydrogenase (SDH) activity were significantly increased in hepatocytes after DHEA treated. In conclusion, our results demonstrated that DHEA reduced lipid droplet accumulation by inhibiting hepatocytes proliferation and enhancing mitochondrial function in primary chicken hepatocytes.

Abstract
Metabolic disorder is a major health problem and is associated with a number of metabolic diseases. Due to native hyperglycaemia and resistance to exogenous insulin, chickens as a model had used in the studies of adipose tissue biology, metabolism and obesity. But no detailed information is available about the comprehensive changes of serum metabolites at different stages of chicken embryonic development. This study employed LC/MS-QTOF to determine the changes of major functional metabolites at incubation day 14 (E14d), 19 (E19d) and hatching day 1 (H1d), and the associated pathways of differential metabolites during chicken embryonic development were analysed using Metabolite Set Enrichment Analysis method. Results showed that 39 metabolites were significantly changed from E14d to E19d and 68 metabolites were significantly altered from E19d to H1d in chicken embryos. Protein synthesis was promoted by increasing the concentrations of L-glutamine and threonine, and gonadal development was promoted through increasing oestrone content from E14d to E19d in chicken embryos, which indicated that serum glutamine, threonine and oestrone contents may be considered as the candidate indicators for assessment of early embryonic development. 2-oxoglutaric acid mainly contributed to enhancing the citric cycle, and it plays an important role in improving the growth of chicken embryos at the late development; the decreasing of L-glutamine, L-isoleucine and L-leucine contents from E19d to H1d in chicken embryonic development implied their possible functions as the feed additive during early posthatch period of broiler chickens to satisfy the growth. These results provided insights into understand the roles of serum metabolites at different developmental stages of chicken embryos, it also provides available information for chicken as a model to study metabolic disease or human obesity.
