RESUMO
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.

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.

Objective: To investigate the impact of intraoperative hypothermia on postoperative outcome in neonatal patients undergoing non-cardiac surgery. Methods: The data of 1 008 neonates undergoing non-cardiac surgery in Children's Hospital, Zhejiang University School of Medicine from January 2020 to October 2022 were retrospectively collected,which included 558 males and 450 females, with a midian age [M (Q1, Q3)] of 6 (2, 14) days. Neonates were divided into 4 groups according to whether hypothermia (below 36 â) occurred and the lowest body temperature during the surgery: normal temperature group (n=246), mild hypothermia group (the lowest temperature ranged 35.0-35.9 â, n=434), moderate hypothermia group (the lowest temperature ranged 34.0-34.9 â, n=232) and severe hypothermia group (the lowest temperature<34 â, n=96). The primary outcome was the incidence of intraoperative hypothermia. The four groups' difference of postoperative hospital stay, postoperative mortality within 30 days, postoperative pulmonary complications, postoperative hemorrhage/blood transfusion and acidosis were compared. Multivariate logistic regression was used to analyze the relationship between intraoperative hypothermia and prolonged postoperative hospital stay (>14 d), 30 d-mortality and other complications. Results: In the 1 008 neonatal patients, 762 (75.6%) cases suffered intraoperative hypothermia, among which the incidence of mild, moderate and severe hypothermia was 43.1% (434/1008), 23.0% (232/1008) and 9.5% (96/1008), respectively. The postoperative hospital stay in normal, mild, moderate and severe hypothermia groups was 9.0 (5.8, 18.0), 12.0 (7.0, 21.0), 17.0 (10.0, 34.5) and 31.5 (12.5, 55.8) days. The mortality rate with 30 days after surgery was 2.9% (7/246), 4.4% (19/434), 6.9% (16/232) and 14.7% (14/96), the incidence of postoperative pulmonary complications was 31.7%(78/246), 39.9%(173/434), 44.8%(104/232) and 67.4%(64/96), the rate of postoperative hemorrhage/blood transfusion was 19.9%(49/246), 32.3%(140/434), 49.1%(114/232) and 79.0%(75/96), and the incidence of acidosis was 26.8%(66/246), 35.7%(155/434), 44.4%(103/232) and 46.3%(44/96), respectively. All differences were statistically significant (all P<0.05). According to the adjusted logistic regression analysis, compared with the normal body temperature group, severe hypothermia was associated with prolonged postoperative hospital stay (OR=1.962, 95%CI: 1.063-3.619) and postoperative pulmonary complications (OR=2.020, 95%CI: 1.149-3.553). The mild, moderate and severe hypothermia group could increase the risk of postoperative blood/transfusion rate (mild: OR=1.690, 95%CI: 1.080-2.644; Moderate: OR=2.382, 95%CI: 1.444-3.927; Severe: OR=8.334, 95%CI: 3.123-8.929). The mild and moderate hypothermia could raise the risk of acidosis (mild: OR=1.458, 95%CI: 1.009-2.107; Moderate: OR=1.949, 95%CI: 1.279-2.972). Conclusion: Intraoperative hypothermia can prolong the postoperative hospital stay, and increase the risk of postoperative mortality, postoperative pulmonary complications, postoperative hemorrhage/transfusion, and acidosis.

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-ß2 glycoprotein â (ß2GPâ )], and triple aPLs positivity (i.e., LA, aCL, and anti-ß2GPâ 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.

A large number of female goats are needed for the dairy goat industry; therefore, the development of a method to ensure the birth of more females than males in a single pregnancy will lead to economic benefits. Increasing the number of X-sperm would be an effective way to increase the proportion of female offspring. In this study, goat semen was incubated at pH 7.4 in alkaline diluent combined with resiquimod (R848) and the number of X-sperm was enriched by the swim-up method. The percentage of X-sperm was determined using the double TaqMan qPCR method. Sperm total motility, progressive motility, average path velocity, straight-line velocity, and curvilinear velocity were measured using a computer-aided sperm analysis system, and the functional parameters of the sperm plasma membrane, the acrosome, mitochondrial activity, ATP content, and reactive oxygen species levels were also measured. Lastly, the ratio of female embryos was determined by in vitro fertilization, and the number of female kids and the pregnancy rate of does was assessed by artificial insemination. The results showed that dilution of semen in an alkaline buffer containing R848 could enrich the number of X-sperm to 85.57% ± 3.27%. The progressive motility, average path velocity, straight-line velocity, curvilinear velocity, mitochondrial activity, and ATP level of the collected X-sperm-enriched semen were significantly reduced, but its total motility, plasma membrane, and acrosome were not affected. The in vitro fertilization experiments showed that the rate of female embryo production using X-sperm-rich seminal fluid could reach 83.25% (174/209), which was significantly higher than the proportion of female embryos in the control group, 47.71% ± 1.80% (104/218). As determined by artificial insemination, the number of female kids in the test group increased by 62.79% (243/387), which was significantly higher than that in the control group (47.65%, 193/405). There was no significant difference in pregnancy rate between the test group and the control group (71.71% vs. 78.48%). Therefore, this study demonstrated that use of a pH 7.4 diluent containing R848 is a simple and effective method of X-sperm enrichment for dairy goat production. Its application would allow does to produce more female offspring for herd expansion and milk production.

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.

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.

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.

Objective: To examine the effective and safe outcomes of drug-coated balloon (DCB) angioplasty for the treatment of femoropopliteal long lesions in mid-term and long-term follow-up. Methods: The clinical data of 114 patients with symptomatic (Rutherford 2 to 6) femoropopliteal long lesions who underwent angioplasty with DCB between June 2016 and May 2021 at Department of Vascular Surgery,Beijing Tsinghua Changgung Hospital were retrospectively analyzed. A total of 75 males and 39 females were enrolled, aged (71.9±8.4)years (range: 49 to 89 years). Among 138 lesions in 114 patients, there were 111 de nove lesions (80.4%, 111/138). Total occlusions were recanalized in 116 limbs (84.1%, 116/138). The lesion length was (280.9±78.7)mm (range: 150 to 520 mm). DCB angioplasty combined with debulking devices was used in 59 lesions (42.8%, 59/138).The bail-out stent implantation was performed in 27 limbs (19.6%, 27/138). The Kaplan-Meier method was used to evaluate cumulative primary patency rate, freedom from the clinically driven target lesion revascularization (CD-TLR) rate and accumulate survival rate. Univariate and multivariate analyses with Cox proportional hazards models were performed to determine the significant prognostic factors for primary patency. Results: DCB angioplasty was completed in 114 patients. The technical success rate was 98.2%(112/114). The mean follow-up time was 18 months (range: 3 to 54 months).The results showed that primary patency rates at 12, 24 and 36 months postoperatively were 87.5%, 75.2% and 55.1%, respectively. Freedom from CD-TLR rate at 12, 24 and 36 months postoperatively were 92.4%, 81.8% and 68.7%, respectively. Accumulate survival rate at 12, 24 and 36 months postoperatively were 96.2%, 94.0% and 80.2%. Multivariate Cox's regression analyses showed that chronic limb-threatening ischemia(CLTI) (HR=2.629, 95%CI:1.519 to 4.547, P<0.01) and hyperlipidemia (HR=2.228, 95%CI: 1.004 to 4.948, P=0.026) were independent prognosis factors for primary patency in DCB treatment of femoropopliteal long lesions. Conclusions: DCB provided favorable outcomes for the treatment of femoropopliteal long lesions. CLTI and hyperlipidemia are independent prognosis factors for restenosis after DCB angioplasty.

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.

Objective: Longitudinally extensive transverse myelitis (LETM) could be seen in patients with connective tissue disease (CTD), especially systemic lupus erythematosus (SLE) or primary Sjögren's syndrome (pSS). Some patients are combined with neuromyelitis optica spectrum disorders (NMOSD)(termed CTD-LETM-NMOSD) while others without (termed CTD-LETM-non-NMOSD). The aim of this study is to compare the clinical characteristics of CTD-LETM-NMOSD patients to CTD-LETM-non-NMOSD patients. Methods: We retrospectively collected data from 40 CTD patients with LETM who were admitted to the Department of Neurology or Rheumatology at Peking Union Medical College Hospital from Jan, 2006 to Dec, 2016. They were divided into CTD-LETM-NMOSD and CTD-LETM-non-NMOSD two groups. Demographic characteristics, clinical and laboratory features were obtained from the database. Relapse rates and clinical outcome were analyzed by Kaplan-Meier method. Results: Among 40 patients with CTD, 28 (70.0%) were NMOSD while 12 (30.0%) were not. The positivity rates of anti-SSA, antibodies to aquaporin-4 (anti-AQP4) were significantly higher in patients with NMOSD than those in patients with non-NMOSD (P<0.05). Age, gender, clinical features, disease duration, anti-double-stranded DNA antibody, anti-ribosomal P antibody, antiphospholipid antibodies, expanded disability status scale (EDSS) scores, and magnetic resonance imaging (MRI) features were all comparable between two groups. CTD-NMOSD patients had significantly higher disease relapse rate (75.0% vs. 3/12, P<0.01). Conclusion: Anti-SSA and anti-AQP4 positivity is associated with NMOSD and higher relapse rates, which suggests that NMOSD in CTD-LETM patients may represent distinct characteristics and pathogenesis from patients with CTD-LETM-non NMOSD.

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-ß2GPâ 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.

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.

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.

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 1â¶1 with the APS cases. IgA/IgG/IgM anticardiolipin antibodies (aCL) and anti-ß2 glycoprotein I antibodies (aß2GPI) 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-aß2GPI was 20.6% and 15.6% in the APS patients, while in the IgG/IgM-aCL or IgG/IgM-aß2GPI negative individuals, the isolated positivity of IgA-aCL and IgA-aß2GPI was only 2.3% and 0.9%, respectively. Accordingly, IgA-aCL and IgA-aß2GPI 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 aß2GPI, the diagnostic efficacy of combined IgG/IgM (AUC=0.875) or IgA/IgG/IgM (AUC=0.875) antibodies was not superior to IgG-aß2GPI 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 aß2GPI, testing IgA-aCL and IgA-aß2GPI cannot further improve the predictive value of APS. However, IgA-aPL is associated with clinical manifestations of APS, including heart valve lesions and thrombocytopenia.

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).

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.

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.
