Abstract
Objective: To evaluate the role of minimal residual disease (MRD) monitoring during early induction therapy for the treatment of childhood acute lymphoblastic leukemia (ALL). Methods: This was a multicenter retrospective cohort study. Clinical data of 1 164 ALL patients first diagnosed between October 2016 and June 2019 was collected from 16 hospitals in South China Children's Leukemia Group. According to MRD assay on day 15 of early induction therapy, they were divided into MRD<0.10% group, MRD 0.10%-<10.00% group and MRD≥10.00% group. According to MRD assay on day 33, they were divided into MRD<0.01% group, MRD 0.01%-<1.00% group and MRD≥1.00% group. Age, onset white blood cell count, central nervous system leukemia (CNSL), molecular genetic characteristics and other data were compared between groups. Kaplan-Meier method was used for survival analysis. Cox regression model was used to analyze prognostic factors. Results: Of the 1 164 enrolled patients, there were 692 males and 472 females. The age of diagnosis was 4.7 (0.5, 17.4) years. The white blood cell count at initial diagnosis was 10.7 (0.4, 1 409.0) ×109/L. Among all patients, 53 cases (4.6%) had CNSL. The follow-up time was 47.6 (0.5, 68.8) months. The 5-year overall survival (OS) and 5-year relapse-free survival (RFS) rates were (93.1±0.8) % and (90.3±1.1) %. On day 15 of early induction therapy, there were 466 cases in the MRD<0.10% group, 523 cases in the MRD 0.10%-<10.00% group and 175 cases in the MRD≥10.00% group. The 5-year OS rates of the MRD<0.10% group, MRD 0.10%-<10.00% group and MRD≥10.00% group were (95.4±1.0) %, (93.3±1.1) %, (85.4±2.9) %, respectively, while the RFS rates were (93.2±1.6) %, (90.8±1.4) %, (78.9±4.3) %, respectively (χ2=16.47, 21.06, both P<0.05). On day 33 of early induction therapy, there were 925 cases in the MRD <0.01% group, 164 cases in the MRD 0.01%-<1.00% group and 59 cases in the MRD≥1.00% group. The 5-year RFS rates in the MRD 0.01%-<1.00% group was lowest among three groups ((91.4±1.2) % vs. (84.5±3.2) % vs. (87.9±5.1) %). The difference between three groups is statistically significant (χ2=9.11, P=0.010). Among ALL patients with MRD≥10.00% on day 15 of induction therapy, there were 80 cases in the MRD <0.01% group on day 33, 45 cases in the MRD 0.01%-<1.00% group on day 33 and 45 cases in the MRD≥1.00% group on day 33. The 5-year RFS rates of three groups were (83.9±6.0)%, (67.1±8.2)%, (83.3±6.9)% respectively (χ2=6.90, P=0.032). Univariate analysis was performed in the MRD≥10.00% group on day 15 and the MRD 0.01%-<1.00% group on day 33.The 5-year RFS rate of children with CNSL was significantly lower than that without CNSL in the MRD≥10.00% group on day 15 ((50.0±20.4)% vs. (80.3±4.4)%,χ2=4.13,P=0.042). Patients with CNSL or MLL gene rearrangement in the MRD 0.01%-<1.00% group on day 33 had significant lower 5-year RFS rate compared to those without CNSL or MLL gene rearrangement ((50.0±25.0)% vs. (85.5±3.1)%,χ2=4.06,P=0.044;(58.3±18.6)% vs. (85.7±3.2)%,χ2=9.44,P=0.002). Multivariate analysis showed that age (OR=0.58, 95%CI 0.35-0.97) and white blood cell count at first diagnosis (OR=0.43, 95%CI 0.27-0.70) were independent risk factors for OS. The MRD level on day 15 (OR=0.55,95%CI 0.31-0.97), ETV6-RUNX1 fusion gene (OR=0.13,95%CI 0.03-0.54), MLL gene rearrangement (OR=2.55,95%CI 1.18-5.53) and white blood cell count at initial diagnosis (OR=0.52,95%CI 0.33-0.81) were independent prognostic factors for RFS. Conclusions: The higher the level of MRD in early induction therapy, the worse the OS. The MRD levels on day 15 is an independent prognostic factor for RFS.The MRD in early induction therapy guided accurate risk stratification and individualized treatment can improve the survival rate of pediatric ALL.

Abstract
Objective: To observe the efficacy and safety of botulinum toxin A (BTA) injection in the treatment of acute comitant esotropia (ACE) with different doses. Methods: This retrospective cohort study included data from patients with ACE who received BTA injection treatment at the First Affiliated Hospital of Zhengzhou University from June 2019 to June 2022. All patients underwent routine ophthalmic examinations, including best-corrected visual acuity (BCVA), spherical equivalent (SE), as well as specialized examinations for strabismus, including the degree of esotropia, eye movement status, and binocular visual function. Patients were categorized into small esotropia [≤60 prism diopters (PD)] and large esotropia (>60 PD) groups based on the pre-treatment degree of esotropia. Each group was further divided into 2.5 U and 5.0 U dose subgroups. Monocular injections were administered to the non-dominant eye. The esotropia degree was recorded and compared at 1, 2, 3, and 6 months of follow-up. The proportion of effectively treated patients in each group was documented. The number of cases with various levels of visual functions (including simultaneous vision, near stereopsis, and distance stereopsis) at 6 months post-treatment was compared, and complications during the follow-up period were observed. Statistical analyses were conducted using t-tests, Mann-Whitney U tests, and χ2 tests. Results: A total of 70 patients were included in the study, comprising 46 males and 24 females, with a median age of 5.0 (4.0, 8.3) years. Among them, 37 patients had small esotropia, with 25 in the 2.5 U group and 12 in the 5.0 U group. Thirty-three patients had large esotropia, with 18 in the 2.5 U group and 15 in the 5.0 U group. There were no statistically significant differences in baseline data, including age, duration of the condition, pre-treatment esotropia degree, BCVA and SE, between the two dose groups in both small and large esotropia patients (all P>0.05). In small esotropia patients, at 1 and 2 months post-treatment, the esotropia degree in the 5.0 U group was -20.00 (-37.50, -7.00) and 0.00 (0.00, 0.00) PD, respectively, which was significantly lower than the 0.00 (-10.00, 4.50) and 5.00 (0.00, 6.50) PD in the 2.5 U group (all P<0.05). At 3 and 6 months post-treatment, the esotropia degree in the 2.5 U group was 5.00 (0.00, 15.00) and 2.00 (0.00, 6.00) PD, respectively, while in the 5.0 U group, it was 0.00 (0.00, 4.50) and 0.00 (0.00, 3.75) PD, with no statistically significant differences between the two groups (all P>0.05). In the 2.5 U group, 20 cases were effectively treated, accounting for 80.0%, while in the 5.0 U group, 10 cases were effective, accounting for 10/12, with no significant difference between the two groups (P>0.05). In the 2.5 U group and the 5.0 U group, the proportions of cases with various levels of visual functions were as follows: simultaneous vision, 76.0% (19/25) and 10/12; near stereopsis, 48.0% (12/25) and 7/12; distance stereopsis, 44.0% (11/25) and 7/12, respectively. No statistically significant differences were observed in these proportions (all P>0.05). In patients with large esotropia, the esotropia degrees in the 5.0 U group at various follow-up times were -5.00 (-25.00, 5.00), 0.00 (0.00, 7.00), 2.00 (0.00, 10.00), and 5.00 (0.00, 7.00) PD, respectively. For the 2.5 U group, the corresponding values were 5.00 (2.75, 27.75), 10.00 (3.75, 24.75), 12.00 (3.75, 38.75), and 14.00 (3.50, 54.00) PD, respectively. The esotropia degrees in the 5.0 U group were consistently lower than those in the 2.5 U group (all P<0.05). The proportion of effective treatment in the 5.0 U group (13/15) was higher than that in the 2.5 U group (9/18), and the proportion of cases with distance stereopsis in the 5.0 U group (9/15) was higher than that in the 2.5 U group (4/18), both showing statistically significant differences (all P<0.05). The number of cases with simultaneous vision and near stereopsis showed no significant differences between the two groups (all P>0.05). The proportion of complications in the 2.5 U and 5.0 U groups in both large and small esotropia patients was 9/18, 13/15, 80.0% (20/25), and 10/12, respectively, with no statistically significant differences (all P>0.05). All complications spontaneously resolved within 3 months post-treatment. Conclusions: BTA injection is effective in the treatment of ACE, and for ACE patients with esotropia degrees greater than 60 PD, increasing the injection dose to 5.0 U can achieve better therapeutic outcomes.

Abstract
Objective: To analyze the efficacy, safety, and long-term prognosis of intermediate-dose cytarabine (Ara-c) regimen in the treatment of children with refractory risk organ involvement Langerhans cell histiocytosis (LCH). Methods: Clinical data of 17 children with multisystem and risk organ involvement LCH who failed the first-line therapy and were treated with intermediate-dose Ara-c (250 mg/m2, twice daily) regimen in the Hematology Center, Beijing Children's Hospital from January 2013 to December 2016 were analyzed retrospectively. In addition to the basic treatment of vindesine and dexamethasone, the patients received two regimens: regimen A: the intermediate-dose Ara-c combined with cladribine and regimen B: the intermediate-dose Ara-c alone. The efficacy, safety and prognosis of the two regimens were analyzed. Results: Among all 17 patients, there were 11 males and 6 females, with the diagnosis age of 2.1 (1.6, 2.7) years. Ten children received regimen A, all of them achieved active disease-better (AD-B) after 8 courses of induction therapy. The disease activity scores (DAS) decreased from 5.5 (3.0, 9.0) to 1.0 (0, 2.3). Seven children received regimen B, and 6 of them achieved AD-B after 8 courses of induction therapy. The DAS decreased from 4.0 (2.0, 4.0) to 1.0 (0, 2.0). The follow-up time was 6.2 (4.9,7.2) and 5.2 (3.7,5.8) years in group A and B. The 5-year overall survival rate was 100.0% in both groups, and the 5-year event free survival rate was (88.9±10.5)% and (85.7±13.2)% in group A and B. Grade 3 or 4 myelosuppression was observed in 8 patients in group A and 2 patients in group B. Conclusions: The intermediate-dose Ara-c regimen (with or without cladribine) is effective and safe for patients with refractory high-risk LCH, with a good long-term prognosis.

Abstract
PURPOSE This study aimed to explore the internal determinants affecting patients' utilization of online medical services (OMS) based on the information-motivation-behavioral skills model from a behavioral perspective. DESIGN A cross-sectional study. SETTING This study was conducted in three medical institutions in Jiangsu Province, China. SUBJECTS 470 internet users were enrolled from patients who came to the outpatient clinics. MEASURES A self-administered questionnaire with feasible reliability and validity was used to investigate the demographic characteristics and OMS utilization-related information, motivation, behavioral skills, intention, and behavior. ANALYSIS According to the constructed framework, structural equation modeling was used to test the relationships between those factors and OMS utilization behaviors. RESULTS All direct paths are established except the path between information and intention. Information and motivation positively affected OMS utilization behavior through behavioral skills and intention (P < .001). Motivation and behavioral skills could positively influence OMS utilization behavior through intention (P < .01). Motivation was found to be the largest predictor of OMS utilization behavior. Moreover, gender played a moderating role in the interpretation of the behavior. CONCLUSIONS Interventions should be conducted regarding information, motivation, and behavioral skills to promote patients' use of OMS. At the same time, the impact of gender on intervention effectiveness should also be considered.

Abstract
Objective: To investigate the association between gestational diabetes mellitus (GDM) and preterm birth subtypes. Methods: Based on the cohort of pregnant women in Anqing Prefectural Hospital, the pregnant women who received prenatal screening in the first or second trimesters were recruited into baseline cohorts; and followed up for them was conducted until delivery, and the information about their pregnancy status and outcomes were obtained through electronic medical record system and questionnaire surveys. The log-binomial regression model was used to explore the association between GDM and preterm birth [iatrogenic preterm birth, spontaneous preterm birth (preterm premature rupture of membranes and preterm labor)]. For multiple confounding factors, the propensity score correction model was used to compute the adjusted association. Results: Among the 2 031 pregnant women with a singleton delivery, the incidence of GDM and preterm birth were 10.0% (204 cases) and 4.4% (90 cases) respectively. The proportions of iatrogenic preterm birth and spontaneous preterm birth in the GDM group (n=204) were 1.5% and 5.9% respectively, while the proportions in non-GDM group (n=1 827) were 0.9% and 3.2% respectively, and the difference in the proportion of spontaneous preterm birth between the two groups was significant (P=0.048). Subtypes of spontaneous preterm were further analyzed, and the results showed that the proportions of preterm premature rupture of membranes and preterm labor in the GDM group were 4.9% and 1.0% respectively, while the proportions in the non-GDM group were 2.1% and 1.1% respectively. It showed that the risk of preterm premature rupture of membranes in GDM pregnant women was 2.34 times (aRR=2.34, 95%CI: 1.16-4.69) higher than that in non-GDM pregnant women. Conclusions: Our results showed that GDM might increase the risk of preterm premature rupture of membranes. No significant increase in the proportion of preterm labor in pregnant women with GDM was found.

Neoadjuvant chemoradiotherapy versus neoadjuvant chemotherapy followed by minimally invasive esophagectomy for locally advanced esophageal squamous cell carcinoma: a prospective multicenter randomized clinical trial. Ann Oncol 2023; 34:163-172. [PMID: 36400384 DOI: 10.1016/j.annonc.2022.10.508] [Citation(s) in RCA: 26] [Impact Index Per Article: 26.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/08/2022] [Revised: 09/29/2022] [Accepted: 10/13/2022] [Indexed: 11/17/2022] Open
Abstract
BACKGROUND Neoadjuvant therapy is recommended for locally advanced esophageal cancer, but the optimal strategy remains unclear. We aimed to evaluate the safety and efficacy of neoadjuvant chemoradiotherapy (nCRT) versus neoadjuvant chemotherapy (nCT) followed by minimally invasive esophagectomy (MIE) for locally advanced esophageal squamous cell carcinoma (ESCC). PATIENTS AND METHODS Eligible patients staged as cT3-4aN0-1M0 ESCC were randomly assigned (1 : 1) to the nCRT or nCT group stratified by age, cN stage, and centers. The chemotherapy, based on paclitaxel and cisplatin, was administered to both groups, while concurrent radiotherapy was added for the nCRT group; then MIE was carried out. The primary endpoint was 3-year overall survival. This study is registered with ClinicalTrials.gov (NCT03001596). RESULTS A total of 264 patients were eligible for the intention-to-treat analysis. By 30 November 2021, 121 deaths had occurred. The median follow-up was 43.9 months (interquartile range 36.6-49.3 months). The overall survival in the intention-to-treat population was comparable between the nCRT and nCT strategies [hazard ratio (HR) 0.82, 95% confidence interval (CI) 0.58-1.18; P = 0.28], with a 3-year survival rate of 64.1% (95% CI 56.4% to 72.9%) versus 54.9% (95% CI 47.0% to 64.2%), respectively. There were also no differences in progression-free survival (HR 0.83, 95% CI 0.59-1.16; P = 0.27) and recurrence-free survival (HR 1.07, 95% CI 0.71-1.60; P = 0.75), although the pathological complete response in the nCRT group (31/112, 27.7%) was significantly higher than that in the nCT group (3/104, 2.9%; P < 0.001). Besides, a trend of lower risk of recurrence was observed in the nCRT group (P = 0.063), while the recurrence pattern was similar (P = 0.802). CONCLUSIONS NCRT followed by MIE was not associated with significantly better overall survival than nCT among patients with cT3-4aN0-1M0 ESCC. The results underscore the pending issue of the best strategy of neoadjuvant therapy for locally advanced bulky ESCC.

Abstract
Objective: To evaluate the efficacy and safety of Beijing Children's Hospital (BCH) modified hemophagocytic lymphohistiocytosis (HLH) 04 regimen in the treatment of childhood HLH. Methods: A retrospective cohort study was conducted. From January 2016 to December 2017, 110 children with HLH who were treated with the modified HLH-04 regimen (replacing dexamethasone with methylprednisolone during the induction period, reducing the dose and frequency of etoposide, and not using cyclosporine except for autoimmune-related HLH) at the Hematology Oncology Center of Beijing Children's Hospital were selected as the modified group, while 102 children treated with the standard HLH-04 regimen from January 2012 to December 2015 were selected as the control group. The early remission rate, survival rate and adverse reactions of two groups were compared. Rank sum test and chi square test were used for comparison between groups. Results: The age of onset in the modified group was 1.9 (1.1, 3.5) years, with 65 males and 45 females. The age of onset in the control group was 2.0 (1.2, 4.6) years, with 47 males and 55 females. No significant difference was found in age and gender between 2 groups (both P>0.05). Except for fibrinogen (1.3 (1.0, 1.7) vs. 1.1 (0.8, 1.4) g/L, Z=-2.67, P=0.008) and natural killer cell activity (13.9 (13.4, 16.3) % vs.14.9 (12.0, 16.1) %, Z=-2.34, P=0.028), there were no statistically significant differences in etiology, disease duration, first clinical presentation, or laboratory tests between 2 groups (all P>0.05). At 2 months and 3 years, there were no statistically significant differences in overall survival between 2 groups (84.5% (93/110) vs.76.5% (78/102), 78.2% (86/110) vs. 67.6% (69/102), χ2=2.28, 3.07, P=0.131, 0.080). The first 3 weeks were the most common time for bone marrow suppression in the modified group, with a lower incidence than in the control group (47.3% (52/110) vs. 62.7% (64/102), χ2=5.11, P=0.024). The modified group had a lower rate of fungal infections than the control group (3.6% (4/110) vs. 13.7% (14/102), χ2=6.93, P=0.008). Compared with the control group, fewer children in the modified group died as a result of side effects from chemotherapy (8.0% (2/25) vs.30.3% (10/33), χ2=4.31, P=0.038). Conclusion: The BCH modified HLH-04 regimen reduced the intensity of chemotherapy, with overall efficacy no worse than the standard HLH-04 regimen, and significantly reduced the rate of chemotherapy-related myelosuppression, fungal infection and mortality.

Abstract
Objective: To investigate the efficacy and safety of ruxolitinib, liposomal doxorubicin, etoposide, methylprednisolone+/-PEG-asparaginase (RU-DEP+/-L) in the treatment of relapsed/refractory (R/R) pediatric hemophagocytic lymphohistiocytosis (HLH). Methods: The clinical data of R/R pediatric HLH, who accepted the RU-DEP+/-L regimen at Beijing Children's Hospital from January 2018 to December 2019 was retrospectively analyzed. Results: A total of 16 patients were included in this study, including 13 males and 3 females, aged[M(Q1,Q3)] 1 (1, 2) years at diagnosis. Thirteen patients were diagnosed with Epstein-Barr virus (EBV)-HLH, 2 with EBV-induced primary HLH, and 1 with unclear etiology, among which 3 patients were co-infected with CMV. After the first-line treatment, 11 patients had no response, and 5 patients relapsed after complete response. Nine patients received the RU-L-DEP regimen, and 7 patients received the RU-DEP regimen. The overall response rate and complete response of RU-DEP+/-L treatment were 10/16 and 3/16, respectively. The negative conversion rate of plasma EBV-DNA was 7/15. The median follow-up time was 35.1 (2.4, 40.7) months, and 9/16 patients were survival. The 3-year overall survival rate after RU-DEP+/-L treatment in response and accepted hematopoietic stem cell transplantation (HSCT) was higher than that without response and did not receive HSCT (P=0.048). Among the 16 patients, 9 had varying degrees of myelosuppression, and 13 had an infection. Conclusions: RU-DEP+/-L can be used as a salvage treatment in R/R pediatric HLH, which can provide a bridge to HSCT and play an important role in the control of HLH. The main adverse reactions are myelosuppression and infection, which can be tolerated.

Abstract
Objective: To analyze the migration of the HIV/AIDS cases and related factors in Liangshan Yi autonomous prefecture (Liangshan). Methods: According to HIV/AIDS Comprehensive Response Information Management System of China Information System for Disease Control and Prevention, a total of 28 772 HIV/AIDS cases who had follow-up records in Liangshan in 2020 were included in the survey. The migration of the HIV/AIDS cases was described and the related factors were analyzed using multiple logistic regression models, and the migration destinations of the HIV/AIDS cases were mapped. Results: Among the 28 772 HIV/AIDS cases, 20.89% (6 010/28 772) had migration in 2020. Multivariate logistic regression analysis showed that among the HIV/AIDS cases, the migration related factors included being aged 15-24 years (compared with being aged 0-14 years, OR=2.74, 95%CI:2.04-3.69) and ethnic group (compared with Han ethnic group, OR=2.44, 95%CI:2.19-2.72), having education level of junior high school (compared with having education level of primary school or below, OR=1.25, 95%CI:1.14-1.38), being unmarried (compared with being married, OR=1.29, 95%CI:1.20-1.39), being engaged in business services (compared with being engaged in farming, OR=1.96, 95%CI:1.31-2.92), receiving antiviral treatment <1 year (compared with receiving antiviral treatment >3 years, OR=1.42, 95%CI:1.26-1.61), having recent CD4+T lymphocytes (CD4) counts >500 cells/μl (compared with having recent CD4 counts <200 cells/μl, OR=1.15, 95%CI:1.03-1.29). The geographical distribution maps showed that among all cities in Sichuan, Xichang (13.26%, 797/6 010) and Chengdu (10.12%,608/6 010) were the main migration destinations of the HIV/AIDS cases, and the provinces outside Sichuan where the HIV/AIDS cases would like to migrate to were mainly Guangdong (18.19%, 1 093/6 010) and Zhejiang provinces (7.67%, 461/6 010) in 2020. The HIV/AIDS cases who migrated where Liangshan, within Sichuan province, and to other provinces accounted for 27.67% (1 663/6 010), 15.34% (922/6 010) and 56.99% (3 425/6 010), respectively. Conclusions: More attention should be paid to the mobility characteristics and the classification management of HIV/AIDS cases according to their characteristics in Liangshan. Timely access to information on changes in the place of work and residence of HIV/AIDS cases should be warranted when they have migration. Good referrals and management for mobility of HIV/AIDS cases in different places should be made to reduce loss to follow-up and improving interventions.

Abstract
Objectives: To examine the prognosis factors of recurrence of esophageal carcinoma within 6 months after neoadjuvant therapy followd by surgery. Methods: The clinical data of 187 patients with esophageal squamous cell carcinoma who underwent neoadjuvant therapy followed by curative esophagectomy between January 2018 and April 2020 at Department of Thoracic Surgery, Shanghai Chest Hospital were analyzed retrospectively. There were 160 males and 27 females, aging (63.0±7.1) years (range:43 to 76 years). The t test, χ2 test and rank-sum test were used for univariate analysis of the prognosis factors for recurrence within 6 months postoperative, while the Logistic regression was used for multivariate analysis. Results: There were 30 patients (16.0%) developed recurrence within 6 months after operation, including local recurrence in 1 case, regional recurrence in 11 cases, hematogenous recurrence in 13 cases, and combined recurrence in 5 cases. Univariate analysis suggested that there was a significant difference in T staging of tumor before neoadjuvant therapy (cT), tumor regression grade, circumferential resection margin, pathological T stage (ypT) and pathological N stage (ypN) between the recurrence patients and non-recurrence patients (all P<0.05). Logistic regression analysis suggested that the cT3-4 (OR=2.701, 95%CI: 1.161 to 6.329, P=0.021) and ypN(+)(OR=1.654, 95%CI: 1.045 to 2.591, P=0.032) were the independent prognosis factors for recurrence within 6 months. Conclusion: The combination of neoadjuvant therapy and surgery is not effective in reducing early postoperative recurrence in patients who have invaded the epineurium before treatment, and still have positive lymph nodes after neoadjuvant therapy.

Abstract
OBJECTIVE To investigate the effectiveness and cost of 50% and 80% wettable powder of niclosamide ethanolamine salt (NESWP) and 26% metaldehyde and niclosamide suspension concentrate (MNSC) in hilly schistosomiasis-endemic regions, so as to provide insights into the selection of chemical molluscicides in hilly regions. METHODS In September 2020, a wasteland in Guanshanqiao Village, Yanrui Township, Yushan County of Jiangxi Province was selected as the experimental region, which was sectioned into five blocks and defined as four experimental groups (A1, A2, B, C) and a blank control group (D). 80% NESWP were given at doses of 1 g/m2 and 1.5 g/m2 in groups A1 and A2 using the spraying method, 50% NESWP was given at a dose of 2 g/m2 in Group B using the spraying method, and 26% MNSC was at a dose of 4 g/m2 in Group C using the spraying method, while no chemical treatment was given in Group D. Snail survey was performed using a systematic sampling method before chemical treatment and 1, 3, 7 d and 15 d post-treatment to examine the molluscicidal effect, and all molluscicidal costs were estimated to calculate the cost of chemical treatment per 1 m2 and the cost of the reduction in the mean density of living snails per 1%. RESULTS The highest mortality of snails was 78.95% and the lowest density of living snails was 0.2388 snails/0.1 m2 in the experimental groups within 7 d of chemical treatment, and the highest mortality of snails was 94.74% and the lowest density of living snails was 0.058 0 snails/0.1 m2 7 d post-treatment. There were no significant differences in the snail mortality among the A1, A2, B and C groups 1 (χ2 = 2.250, P > 0.05), 3 (χ2 = 1.779, P > 0.05) or 15 d post-treatment (χ2 = 2.286, P > 0.05), while a significant difference was detected in the snail mortality among the four groups 7 d post-treatment (χ2 = 7.990, P = 0.046). In addition, there were no significant differences in the snail mortality between A1 and A2 groups 1 (χ2 = 0.724, P > 0.05), 3 (χ2 = 0.584, P > 0.05), 7 (χ2 = 0.400, P > 0.05) or 15 d post-treatment (χ2 = 0.251, P > 0.05). The costs of chemical treatment per 1 m2 were 0.58, 0.60, 0.64 Yuan and 0.73 Yuan in groups A1, A2, B and C, and the costs of the mean density of living snail per 1% reduction were 19.29, 20.44, 21.68 Yuan and 23.53 Yuan in groups A1, A2, B and C, respectively. CONCLUSIONS 80% NESWP shows a high molluscicidal efficacy and low cost in hilly schistosomiasis-endemic regions.

Online medical services utilization evaluated through the lens of socioecological theory and the information-motivation-behavioral skills model: evidence from China. Ann N Y Acad Sci 2021; 1500:82-92. [PMID: 33983658 DOI: 10.1111/nyas.14609] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/26/2020] [Revised: 04/13/2021] [Accepted: 04/21/2021] [Indexed: 12/01/2022]
Abstract
Online medical services (OMS) have become increasingly advantageous, but there are still several barriers to utilization among patients. This study aims to explore the factors influencing OMS utilization (OMSU) for patients in micro-, meso-, and macrosystems based on socioecological theory (SET) and from the perspective of the information-motivation-behavioral skills (IMB) model. We selected 1065 participants through multistage stratified cluster random sampling in Jiangsu, China. In microsystems, information and behavioral skills were positively associated with intention (β = 0.84; β = 3.21) and actual utilization (OR = 1.69; OR = 1.69). Education level (β = 0.83) and personal motivation (β = 1.68) were positively related to intention. Chronic diseases (OR = 2.03) had a positive relationship with actual use. In mesosystems, recommendations from people around the patients (β = 1.14; OR = 1.99), provision of OMS in the nearest primary medical facility (β = 0.98; OR = 3.60), and provision of instructional information by medical institutions (β = 1.01; OR = 1.65) were related to OMSU. The average monthly household income (β = 0.54) was related to intention. Patients who had information about the OMSU experiences of people around them (OR = 1.73) correlated with actual utilization. In macrosystems, the social medical insurance type (OR = 0.66) was associated with OMSU. This study supports the applicability of the SET and IMB model to interpret patients' OMSU.

The Epidemiological Characteristics of Late-Onset Hypogonadism in Chinese Middle-Aged and Elderly Men: Two Cross-Sectional Studies in the Same Community. Am J Mens Health 2020; 14:1557988320977991. [PMID: 33305661 PMCID: PMC7734522 DOI: 10.1177/1557988320977991] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/05/2020] [Revised: 11/07/2020] [Accepted: 11/11/2020] [Indexed: 11/17/2022] Open
Abstract
The purpose of this study was to investigate the prevalence and epidemiological characteristics of late-onset hypogonadism (LOH) in middle-aged and elderly Chinese men. Two cross-sectional studies were conducted at 5-year intervals in community-dwelling men living in the same area. A total of 1472 (Study 1, S1) and 944 (Study 2, S2) men aged 40-69 years old were recruited as subjects. Subjects were evaluated through combining serum reproductive hormone levels with the Androgen Deficiency in Aging Males (ADAM) questionnaire and the Aging Males' Symptoms (AMS) scale. A significant difference was found in mean testosterone deficiency (TD) prevalence between S1 and S2, using either serum total testosterone (TT; 14.02% vs. 6.36%) or serum calculated free testosterone (cFT; 43.69% vs. 16.53%) cutoff values. According to the S1 or S2 data, the mean prevalence of LOH was 37.85%/15.47% in the positive ADAM test and 15.42%/9.43% in the positive AMS test (p < .01). According to classifications of TD based on gonadal status, the prevalence of secondary TD (27.34%) was higher than the primary (16.36%) and compensated (15.42%) TD in S1 (p < .01). However, there were significant differences among the prevalence of primary (6.89%), secondary (9.64%), and compensated (27.65%) TD in S2 (p < .05). Different types of testosterone levels, TD cutoff values, and questionnaires influenced the prevalence of TD and LOH. The serum FT cutoff value was an optimal threshold for evaluating and diagnosing TD and LOH, whose prevalence increased gradually with male aging.

Abstract
Objectives: This paper constructs a comprehensive evaluation index of the traditional Chinese medicine (TCM) medical service system and summarizes the development of TCM medical services in China. Methods: We chose 31 provinces' TCM hospitals as research objects. The data were obtained from the Health Statistics Yearbook from 2013 to 2018 and from the National Statistics of Chinese Medicine from 2012 to 2017. The approaches to factor analysis and TOPSIS are used in this paper. It is found that the comprehensive evaluation indexes of the TCM medical service system can be divided into 4 first-level indicators and 14 second-level indicators. Results: The development of the TCM medical service system in China is unbalanced and inadequate. North China and East China are generally superior to Northwest and Southwest China in terms of revenue and expenditure for TCM medical services. The per capita of medical resources in the Southwest and Northwest are stronger than those in Central and South China, but overall medical resources are weaker than those in East China and North China. TCM medical service institutions in East China, South China and Central China have achieved better service results and higher economic benefits with less resource input, which further indicates the efficient allocation of resources and the balanced operation of TCM medical service institutions. Conclusion: The development of China's TCM medical service system shows the imbalance and inadequacy of “East is strong, West is weak” and “South is superior, North is inferior.”

Abstract
Air-breathing marine predators have been essential components of the marine ecosystem since the Triassic. Many of them are considered the apex predators but without direct evidence-dietary inferences are usually based on circumstantial evidence, such as tooth shape. Here we report a fossil that likely represents the oldest evidence for predation on megafauna, i.e., animals equal to or larger than humans, by marine tetrapods-a thalattosaur (∼4 m in total length) in the stomach of a Middle Triassic ichthyosaur (∼5 m). The predator has grasping teeth yet swallowed the body trunk of the prey in one to several pieces. There were many more Mesozoic marine reptiles with similar grasping teeth, so megafaunal predation was likely more widespread than presently conceived. Megafaunal predation probably started nearly simultaneously in multiple lineages of marine reptiles in the Illyrian (about 242-243 million years ago).

Abstract
Objective: To examine the preliminary clinical efficacy of Chinese magnetic sphincter augmentation (MSA) in the treatment of gastroesophageal reflux disease (GERD). Methods: According to the enrollment criteria for the MSA developed by ShengJieKang Co. and Shanghai Chest Hospital (SS-MSA) clinical trial, a total of 19 GERD patients were treated with SS-MSA from August 2018 to January 2020 at Department of Thoracic Surgery, Shanghai Chest Hospital, Shanghai Jiao Tong University. The majority of registered cases were male patients with age of (32.2±7.3) years (range: 22 to 50 years), height of (170.7±6.2) cm (range: 160 to 179 cm) and weight of (65.2±10.3) kg (range: 47.5 to 90.0 kg). SS-MSA was implanted via laparoscopy. The major evaluation indexs of postoperative efficacy were the total time of acid exposure within 24 hours and the total number of reflux. Secondary efficacy indicators included: (1) evaluation of the average daily dose of proton pump inhibitor medications; (2) the score of GERD health related quality of life questionnaire (GERD-Q) before and after MSA implantation. Paired design t-test was used to evaluate the efficacy of the SS-MSA. Results: A total of 19 patients underwent SS-MSA surgery successfully. The history of the GERD were 19 (54) months (M(Q(R))). The operation time was 63 (22) minutes and the in-hospital stay was 3 (2) days. No obvious surgical complications occurred. Postoperative adverse events included 14 cases with mild to moderate dysphagia exited after surgery, gradually eased within 1 to 3 months, 1 case with the removal of the device after 1 month of severe swallowing difficulties, 1 case of diarrhea. No corrosion, perforation, displacement occurred. The GERD-Q score (11.0(4.5) vs. 6(1.0), t=4.274, P=0.013), 24-hour acid exposure time (6.2(4.8)% vs. 0.1(0.9)%, t=5.814, P=0.004), and Demeester score (23.72(16.20) vs. 0.96(3.10), t=6.678, P=0.003) were significantly decreased 1 year after surgery(n=5). Proton pump inhibitor reuse rates were 6/18, 5/15, 3/10, and 1/5 in 1, 3, 6 and 12 months after the operation, respectively. Conclusions: SS-MSA implantation is feasible and safe with short hospital stay and rare perioperative complications. The preliminary results is good after 1 year follow-up. It could be expected to be an ideal substitutive for future GERD treatment.

Abstract
The lower esophageal sphincter incompetent is fundamental pathological abnormality of gastroesophageal reflux disease (GERD). Magnetic sphincter augmentation (MSA) is a magnetic bracelet, which designed to be placed surgically around the exterior surface of the distal esophagus. In the closed position, the highest attractive force between the magnetic beads would reinforce the lower esophageal sphincter to strengthen the antireflux barrier. Animal experiments and clinical trials have verified the safety and efficacy of MSA in GERD patients. For refractory GERD and GERD with huge hernia, MSA can also achieve acceptable clinical effect. Comparative researches appeared that there is no significantly difference in clinical effect between Nissen fundoplication and MSA. MSA could preserve the function of belching and vomiting postoperatively, and it can be implanted with the use of standard laparoscopic techniques. The long-term effect of MSA is satisfactory with less complications, which has been carried out in China since 2018. It can be predicted that MSA will play an important role in the treatment of GERD in the future.

Abstract
To investigate the age-related nomograms and change trends of reproductive hormones, and prevalence of androgen deficiency (AD) in middle-aged and aging men from 2 studies.Two cross-sectional studies were conducted at 5-year intervals in Chinese community-dwelling men living in the same area. A total of 434 (Study 1, S1) and 944 (Study 2, S2) men aged 40 to 69 years were recruited as subjects and 59 (S1) and 98 (S2) men aged 20 to 39 years as controls to measure serum reproductive hormone levels.Serum total testosterone (TT) levels did not change significantly in S1, whereas TT levels increased in S2 with aging. Serum calculated free testosterone (cFT) levels gradually decreased with aging; however, only men aged 40 to 69 years showed this trend in S2. Serum luteinizing hormone (LH) and sex hormone binding globulin (SHBG) levels gradually increased, and serum testosterone secretion index (TSI) and free testosterone index (FTI) levels gradually decreased with male aging. The mean annual decrease values of serum cFT were 2.705 pmol/l in S1 and 1.060 pmol/l in S2. The cut-off values for AD in S1 and S2 were 9.13 nmol/l and 9.35 nmol/l for TT, and 169.00 pmol/l and 213.90 pmol/l for cFT. Using TT or cFT cut-off values, mean AD prevalence was 14.52% or 44.70% in S1, and 6.36% or 16.53% in S2. Based on cFT cut-off values, prevalence of AD increased gradually with male aging in a range of 25.30% to 61.63% in S1 and 1.20% to 23.03% in S2.The change patterns of serum LH, SHBG, TSI and FTI levels in middle-aged and aging males were consistent; however, there were differences in serum TT and cFT change patterns in S1 and S2 with male aging. cFT cut-off values were the optimal metric to evaluate AD, which can be present a ladder-like change in prevalence of different age groups.

Abstract
Objective: To investigate the relationship between single nucleotide polymorphisms of opioid-related genes and high-dose opioid tolerance in patients with cancer pain. Methods: Twenty patients (high-dose opioid tolerance group, group A) who were hospitalized in Henan Cancer Hospital from June 2016 to June 2018 and who received high-dose opioid for pain control for more than 1 week were selected as case groups (group A). Thirty patients with stage Ⅳ tumors who were hospitalized in Henan Cancer Hospital and did not have opioid tolerance were randomly selected as the control group (group B). The peripheral blood samples of two groups were taken for DNA extraction. Gene polymorphisms were detected in 15 single nucleotide polymorphisms (SNP) (rs1799971, rs754891060, rs200637194, rs1045642, rs7438135, rs7439366, rs2242480, rs1080985, rs529520, rs581111, rs2234918, rs4680, rs6276, rs3732765, rs9859538) of the nine opioid receptor-related genes (OPRM1,ABCB1,UGT2B7,CYP3A4,CYP2D6,OPRD1, COMT,DRD2,P2RY12) which most likely to affect high-dose opioid tolerance in patients with cancer pain. Results: The distribution of different genotypes of rs7438135 locus in UGT2B7 gene were statistically significant between the two groups (χ(2)=9.68, P=0.004). The difference in the distribution of the different genotypes of the rs3732765 locus of the P2RY12 gene in the two groups were at the significant edge (χ(2)=5.57, P=0.05). A correlation analysis between the relevant SNP locus and the risk of high-dose opioid tolerance in cancer patients indicated that individuals with rs7438135 GA genotype in cancer patients were at 6.19 times more likely to have high doses of opioid tolerance than individuals with AA genotypes. Conclusions: The rs7438135 locus gene polymorphism of UGT2B7 gene may be a risk predictor for high-dose opioid tolerance. The rs3732765 site of the P2RY12 gene may be a potential predictor of high-dose opioid tolerance.

Abstract
Canine kobuvirus (CaKoV) is a newly emerging virus in dogs, which relates to the diarrhea of dogs. To investigate the CaKoV infection in dog population, fecal samples of dogs were collected from three provinces of China in 2015. The results of genetic analysis based on the complete VP1 gene showed that six CaKoVs isolates in this study were closely related with the Chinese canine originated isolate CH1 (90.6%-91.9% nucleotide identities). The phylogenetic analysis demonstrated that the Chinese isolates clustered into a unique branch compared with isolates from other countries. The present study suggested that the CaKoVs had established infection in Chinese dog population. The systematic epidemiological investigation should be further carried out to evaluate the prevalence of the CaKoV infection in China.

Abstract
OBJECTIVE To explore the role of Ter cells in the development of the collagen-induced arthritis (CIA), we detected their quantity changes in the spleen of different stages of CIA mice and analyzed the correlation between Ter cells and the joint scores, and we also analyzed the correlation between Ter cells and the frequencies of T and B cell subsets, so as to further understand the pathogenesis of rheumatoid arthritis. METHODS The six to eight weeks DBA/1 mice were used to prepare CIA model. After the second immunization, we began to evaluate the joint score. According to the time of CIA onset and the joint score, the CIA mice were divided into three stages: early, peak and late stages. According to the final joint score, the CIA mice at the peak stage were subdivided into the high score group (score>8) and the low score group (score≤8). The frequencies of Ter cells in the spleen of the naïve mice and the CIA mice at various stages and the frequencies of T and B cell subsets in the spleen of the CIA mice at the peak stage were detected by flow cytometry, then we carried on the correlation analysis. RESULTS The frequencies of Ter cells in the spleen of the CIA mice was significantly higher than those of the naïve mice (8.522%±2.645% vs. 1.937%±0.725%, P<0.01), the frequencies of Ter cells in the spleen of the high score group mice was significantly lower than those of the low score group (6.217%±0.841% vs. 10.827%±0.917%, P<0.01). The frequencies of Th1 cells in the spleen of the high score group mice was significantly higher than those of the low score group mice (1.337%±0.110% vs. 0.727%±0.223%, P<0.05). The frequencies of Th17 cells in the spleen of the high score group mice was higher than those of the low score group mice (0.750%±0.171% vs. 0.477%±0.051%, P=0.099). The frequencies of germinal center B cells in the spleen of the high score group mice was significantly higher than those of the low score group mice (1.243%±0.057% vs. 1.097%±0.015%, P<0.05). Correlation analysis results showed that the frequencies of Ter cells in the spleen of the CIA mice at the peak stage was strongly negatively correlated with the frequencies of CD4+ T, Th1, Th17, and germinal center B cells, and was strongly positively correlated with the frequencies of B10 cells, indicating that these cells might have a protective effect in CIA. Studies on dynamic changes showed that the frequencies of Ter cells in the spleen of the CIA mice at the late stage was significantly lower than those at the peak stage (0.917%±0.588% vs. 8.522%±2.645%, P<0.001), suggesting the protective effect of these cells in arthritis. CONCLUSION Ter cells were significantly increased in the spleen of the CIA mice at peak stage, and were negatively correlated with joint scores and pathogenic immune cells, and positively correlated with protective immune cells. Ter cells were significantly decreased in the spleen of the CIA mice at the late stage. What we mentioned above suggests that Ter cells might be involved in the progression of rheumatoid arthritis as an immunomodulatory cell,but further in vivo and in vitro experiments are needed to verify its specific effects and mechanism.

Abstract
Objective: To observe the cellular damage of low-dose combined exposure to Hg, Pb and Cd on hippocampal neurons in rat. Methods: SH-SY5Y cells were randomly divided into 8 groups by 2×2×2 factorial design: control group, Pb exposure group, Hg exposure group, Pb+Hg exposure group, Pb+Cd exposure group, Hg+Cd exposure group and Pb+Cd+Hg exposure group. And the cell viabilities were measured. On this basis, an animal model was established. Twenty eight-week-old SD pregnant rats were randomly divided into four groups by random number table, and five in each group: the control group(distilled water), 1-fold metal mixture exposure group (1×MM, poisoning solution containing mercury chloride 0.15 mg/L, lead acetate trihydrate 25 mg/L, cadmium chloride 7.5 mg/L), 5-fold metal mixture exposure group (5×MM, poisoning solution containing mercury chloride 0.75 mg/L, lead acetate trihydrate 125.00 mg/L, cadmium chloride 37.50 mg/L), 10-fold metal mixture exposure group (10×MM, poisoning solution containing mercury chloride 1.50 mg/L, lead acetate trihydrate 250.00 mg/L, cadmium chloride 75.00 mg/L). Pregnant rats drank water until delivery. Twenty male pups were selected and exposed to these metals through breast milk until weaned. The heavy metals dose of poisoning water was adjusted, and then the weaned rats were exposed to heavy metals via drinking poisoning water until adulthood (postnatal day 83). The blood samples and brain hippocampus samples were collected to observe the ultrastructural changes of hippocampus, and to determine the levels of Hg, Pb and Cd in blood. In addition, apoptosis rate and fluorescence intensity of reactive oxygen species and intracellular free calcium concentration ([Ca(2+)](i)) in hippocampal neurons were measured. Results: Cellular factorial design analysis showed that Hg+Pb+Cd (at no observed adverse effect level, 1.0, 0.5 and 0.1 μmol/L, respectively)had a interaction on cell viability after 48 or 72 hours of combined exposure (P<0.05). The results of ultrastructure showed that mitochondria decreased, ridges and matrixes gradually dissolved in rat hippocampal neurons of 5×MM group; nuclear chromatin aggregated, more ridges and matrixes dissolved and the mitochondria also decreased in rat hippocampal neurons of 10×MM group. The concentration of Hg, Pb and Cd in the blood of 1×MM group, 5×MM group and 10×MM group were higher than those in the control group, and the differences were statistically significant (P<0.001). There was no significant difference in apoptosis rate between the 1×MM group and the control group. The apoptosis rate of 5×MM group and 10×MM group was higher than that in the control group, and the differences were statistically significant (P<0.001). There was no statistically significant difference in the fluorescence intensity of reactive oxygen species in hippocampal neurons of the 1×MM group and the control group. The fluorescence intensity of reactive oxygen species in the 5×MM group and the 10×MM group was higher than that in the control group, the difference was statistically significant (P<0.05). There was no significant difference in the fluorescence intensity of [Ca(2+)](i) between the 1×MM group and the control group. The fluorescence intensity values of [Ca(2+)](i) in the 5×MM group and the 10×MM group were higher than the control group, the differences were statistically significant (P<0.001). Conclusion: Low-level combined exposure to Hg, Pb, and Cd caused synergistic neurotoxic damage, and the process may be related to the changes of neuronal apoptosis, reactive oxide species, and [Ca(2+)](i) levels.

Abstract
To investigate the contamination characteristics of PFASs in aquatic products, 254 samples belonging to 6 species, including fishes, crustaceans, cephalopods, etc., were collected from Guangzhou, and 23 PFASs were determined by UPLC-MS/MS. The total detection rates of the various sample species ranged from 93.5% to 100%, and the concentrations of PFASs were relatively higher in the fishes and crustaceans. 13 PFAS components were detected in the fish samples, but only 6 PFAS components were detected in haliotis samples, and obvious differences were observed among the different species sampled. PFOA and PFOS were the predominant pollutants, with detection rates of 75.6% and 76.8%. The concentrations of PFOS were in the range of 0.19-192.27 μg·kg-1, which were obviously higher than those of the other PFAS components, and their total contamination contribution factor reached the highest percentage of 35.15%. PFOS was a major contributing factor to the PFAS contamination of fishes, crustaceans, siphonopods, and processed products; however, the predominant pollutant in Haliotis samples was PFBA. The results of the risk assessment indicated that the concentrations of PFOA and PFOS would not give rise to timely harm to the consumers.

Abstract
Robotic assisted surgery system is the most advanced minimally invasive surgical platform in the world, and this system has been widely used in cardiac surgery, urology surgery, gynecology surgery and general surgery. Although the application of this system was relative late in esophageal surgery, it has been developing vigorously. According to the research progress and practical experience in the world, robot assisted minimally invasive esophagectomy (RAMIE) has the same safety and effectiveness as traditional open esophagectomy (OE) and thoracoscopic laparoscopic esophagectomy (TLE). In this paper, several aspects on this novel operation were demonstrated, including the origin, safety evaluation, lymph node dissection, learning curve, prognosis of RAMIE, comparison among RAMIE, OE and TLE and the role of RAMIE in multidisciplinary treatment of esophageal cancer, in order to promote the rational application of RAMIE in esophagectomy.

Abstract
Immunoglobulin G4-related sialadenitis (IgG4-RS) is a newly recognized immune-mediated disease and one of immunoglobulin G4-related diseases (IgG4-RD). Our multidisciplinary research group investigated the clinicopathological characteristics and diagnosis of IgG4-RS during the past 10 years. Clinically, it showed multiple bilateral enlargement of major salivary glands (including sublingual and accessory parotid glands) and lacrimal glands. The comorbid diseases of head and neck region including rhinosinusitis, allergic rhinitis, and lymphadenopathy were commonly seen, which could occur more early than enlargement of major salivary glands. Internal organ involvements, such as autoimmune pancreatitis, sclerosing cholangitis, and interstitial pneumonia could also be seen. Thirty-five (38.5%) patients had the symptom of xerostomia. Saliva flow at rest was lower than normal. Secretory function was reduced more severely in the submandibular glands than in the parotid glands. Serum levels of IgG4 were elevated in almost all the cases and the majority of the patients had increased IgE levels. CT, ultrasonography, and sialography showed their imaging characteristics. Histologically it showed marked lymphoplasmacytic inflammation, large irregular lymphoid follicles with expanded germinal centers, prominent cellular interlobular fibrosis, eosinophil infiltration, and obliterative phlebitis. Their immunohistological examination showed marked IgG-positive and IgG4-positive plasma cell infiltration and high IgG4/IgG ratio. The disease could be divided into three stages according to severity of glandular fibrosis. The serum IgG4 level was higher and the saliva secretion lower as glandular fibrosis increased. IgG4-RS should be differentiated from other diseases with enlargement of major salivary gland and lacrimal gland, such as primary Sjögren syndrome, chronic obstructive submandibular sialadenitis, and eosinophilic hyperplastic lymphogranuloma.

Abstract
Objective: To analyze the 20-year survival rate, causes of death and predictors of systemic lupus erythematosus (SLE). Methods: A retrospective analysis was performed on 217 newly SLE patients who were diagnosed and treated by Peking University People's Hospital before June 2008. The clinical features and serologic data were studied. Survival rate of SLE patients over time, living conditions, causes of death and prognostic indicators of mortality were studied. Results: The 10-, 15-and 20-year cumulative survival rate was 90.3%,88.1%and 79.6%, respectively. Infection and lupus encephalopathy were the main causes of death. Cox regression analysis revealed that lupus nephritis, neuropsychiatric systemic lupus erythematosus and age at the diagnosis were independent risk determinants for mortality. Conclusion: Prognosis of SLE remains to be improved. Early diagnosis, control of SLE organ damage and infection prevention are critical to improve survival of SLE patients.

Abstract
A practical multi-residue method based on ultra-performance liquid chromatography/tandem mass spectrometry was developed for the simultaneous determination of 23 perfluorinated alkylated substances (PFASs) in water and suspended particles. Suspended particle samples were extracted with 1% formic acid-acetonitrile and cleaned by matrix solid phase dispersion extraction using a C18 sorbent and graphitized carbon black. Water samples were filtered through 0.7-μm glass fiber membranes and enriched utilizing weak anion exchange cartridges. The eluent was dried under a gentle stream of N2 at 45°C and suspended in 1 mL acetonitrile-5 mM ammonium acetate (1:1, vol:vol). Gradient elution for chromatographic separation utilized acetonitrile and 5 mM ammonium acetate as mobile phases on a reverse phase C18 column. The compounds were quantified using an internal standard method in multiple reaction-monitoring mode. Limits of detection and quantitation of the 23 PFAS test compounds in water samples were 0.5-10 ng L-1 and 2-20 ng L-1, respectively. Recoveries at three fortified levels of 20, 50, and 200 ng L-1 ranged from 68.5% to 118% with relative standard deviations below 9.6%. We used this method to determine PFAS levels in real water and suspended particle samples and found high sensitivity and good reproducibility.

Abstract
OBJECTIVE To investigate the changes of bone mineral density (BMD) and serum bone turnover factor in newly diagnosed systemic lupus erythematous (SLE) patients. METHODS Eighty newly diagnosed SLE patients and 80 age and gender matched healthy controls were enrolled. None of the SLE patients had ever received glucocorticoid, immunosuppressive agents or vitamin D. BMD was measured at radius,lumbar spine and hip by dual X ray absorptiometry (DXA). Bone turnover markers including serum levels of tartrate-resistant acid phosphatase 5b (TRAP5b),bone alkaline phosphatase (BAP) and 25-hydroxy vitamin D3 (25-OH-VD3) were measured by enzyme-linked immunosorbent assay (ELISA). Logistic regression was employed to analyze the risk factors associated with decreased BMD. RESULTS Mean age of the SLE patients was (32.8±12.4) years, and 85% were female, none of whom were post-menopausal. BMD was significantly reduced in all the measured sites, compared with the healthy controls. Sixteen (20%) of the patients were osteopenic in at least one site measured locations. The serum levels of 25-OH-VD3 were markedly reduced in the newly diagnosed SLE patients than those of the normal controls [(46.1+12.3) nmol/L vs. (25.4+11.2) nmol/L, P<0.001)]. The serum levels of 25-OH-VD3 in the SLE patients with nephritis were much lower than those without nephritis (P=0.04). A significant negative correlation was demonstrated between the serum concentration of 25-OH-VD3 and the disease activity scores as measured by SLE disease activity index (SLEDAI) (r=-0.3,P=0.001). The serum TRAP5b concentration was positively correlated with SLEDAI (r=0.435,P=0.003). Age (P=0.058) and SLEDAI (P=0.085) were probably associated with decreased BMD in Logistic regression analysis. CONCLUSION The study showed reduced BMD in untreated SLE patients. The role of chronic inflammation was of probable importance in bone metabolism.

Abstract
OBJECTIVE To investigate the clinical characteristics, the medicine application and to evaluate the disease activity in patients with osteoarthritis (OA) in China. METHODS This was a cross-sectional study. Totally 1 066 cases of OA from 40 hospitals in China from April to October 2017 were retrospectively enrolled. Demographic characteristics, clinical data, medicine application, and joint function were evaluated. All the data were analyzed by SPSS software 19.0. t test, Mann-Whitney U test and chi-square test were used for statistical analysis. RESULTS In the 1 066 cases, the male-to-female ratio was 1:3.6 and the average age was (61.9±11.0) years, with an age range from 36 to 94 years. The incidence of knee OA, hip OA, and hand OA were respectively 81.9% (873/1 066), 14.1% (150/1 066), and 36.3% (387/1 066). In the study, 242 (22.7%) cases had two kinds of joint areas involved and three joint areas were involved in 51 cases (4.8%), and 56.6% (603/1 066) of the patients used more than one kind of non-steroid anti-inflammatory drugs (NSAIDs) while 61.2% (652/1 066) used disease modifying osteoarthritis drugs (DMOADs), including glucosamine (37.5%, 400/1 066), chondroitin sulfate (2.0%, 21/1 066), diacetate (5.9%, 63/1 066), and the combination of these drugs (15.8%, 168/1 066). 8.6% (92/1 066) patients only took analgesics to relieve the pain, not using any kind of NSAIDs or DMOADs. And 232 patients (21.7%) had intra-articular injections, including 9.2% (98/1 066) sodium hyaluronate, 4.5%(48/1 066) glucocorticoid, and 8.1% (86/1 066) combination of the two drugs. The proportion of the patients taking topical drugs accounted for 26.5% (283/1 066) and physical therapy accounted for 15.8% (168/1 066). Compared with those who suffered from knee OA, the patients who suffered from hip OA had more severe disease assessment. Moreover, there were significant differences in pain (Z=-7.625, P<0.001), morning stiffness (Z=-6.229, P<0.001), and joint function (Z=-6.777, P<0.001) between the two groups of the patients who suffered from knee or hip OA with The Western Ontario and McMaster Universities (WOMAC) osteoarthritis index. Furthermore, patients with hip OA took more analgesics (χ2=24.838, P<0.001). CONCLUSION Oral NSAIDs and DMOADs are wildly used in patients with OA in China. However, the treatment of some patients still need to be improved. Patients with hip OA are more seriously ill and require aggressive treatment.

Abstract
OBJECTIVE To detect receptor activator of nuclear factor kappa B ligand (RANKL) expressed on B10 cells in rheumatoid arthritis (RA) and to evaluate the correlation between RANKL-producing B10 cells in RA and clinical features and laboratory parameters, trying to reveal the possible role of B10 cells in the pathogenesis of RA and the potential mechanism of impaired immunosuppressive capacities. METHODS 25 RA patients and 20 healthy volunteers were enrolled. These RA patients did not received treatment with glucocorticoids, disease-modifying anti-rheumatic drug and biologics during the recent half of a year. The levels of RANKL-producing B10 cells were measured by flow cytometry (FCM) and polymerase chain reaction (PCR). The correlation between the frequencies of RANKL-producing B10 cells in RA and clinical data, laboratory parameters were analyzed. The role of tumor necrosis factor α (TNF-α) and interleukin 1β (IL-1β) in inducing RANKL expression in B10 cells was evaluated by in vitro stimulation assay. Independent samples t test, Pearson and Spearman correlation were used for statistical analysis. RESULTS B10 cells were capable of producing RANKL at a low level in health controls. The frequencies of RANKL-producing B10 cells were markedly higher in RA patients than in health controls (3.65%±1.59% vs. 2.25%±0.68%, P<0.01). The frequencies of these cells correlated positively with RA tender joint counts, swollen joint counts and disease activity score in 28 joints (DAS28) (r=0.479, P=0.035; r=0.519, P=0.008; r=0.526, P=0.019). However, no correlation was found between these cells and RA patient age, disease duration, or the levels of erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), rheumatoid factor (RF) and anti-citrullinated peptide antibody (ACPA). After in vitro stimulation by TNF-α, but not IL-1β, B10 cells isolated from healthy donors demonstrated fundamentally upregulated expression of RANKL. CONCLUSION Our studies showed the frequencies of RANKL-producing B10 cells were markedly higher in RA patients, and their frequencies were positively correlated with RA tender joint counts, swollen joint counts and DAS28. These findings suggested that B10 cells might be involved in RA bone destruction.

Abstract
OBJECTIVE To comprehend clinical features and patient's physician visit patterns at onset of immunoglobulin G4 related disease (IgG4RD). METHODS In the study, 100 patients with IgG4RD who received treatments in the Department of Rheumatology and Immunology of Peking University People's Hospital from Apr. 1st, 2017 to Apr. 1st, 2018 were investigated, including gender, age, height, body weight, age of onset, physician visit history, primary history and how did the disease affected their life, etc. RESULTS: In this 100 IgG4RD cohort (57 males and 43 females), the male/female ratio was 1:0.75, the mean age of onset was (51.51±12.9) years, and the median duration was 49 months (ranging from 4 to 231 months). The onset age of males was significantly older than that of females (P<0.01). The manifestations showed that up to 69% patients had submaxillay glands lesion, 59% patients had lacrimal glands lesion, 28% patients had pancreas involvement and 28% patients had parotid glands involvement. The females had more lacrimal glands involvement (P<0.05). 62% patients were complicated with anaphylactic disease. The primary physician visit departments concentrated upon general surgery department (19/100), oral and maxillofacial surgery department (17/100), rheumatology and immunology department (16/100), ophthalmology department (15/100) and gastroenterology department (10/100). The departments where the confirmed diagnose was made concentrated upon rheumatology department (67/100),oral and maxillofacial surgery department (16/100) and gastroenterology department (7/100). The mean diagnosis duration after 2010 was (16.96±2.163) months, significantly shorter than that before 2010, which was (113.3±11.01) months. Before the definite diagnose was made, 43% patients underwent surgeries and 12% patients had more than one time surgeries. The patients whose first-visit department was a surgery department were more likely to undergo surgeries (P<0.01). 18% patients (18/100) stated that the disease had affected their work. CONCLUSION In this cohort of the IgG4RD patients, female is common and has earlier onset age than male. The major manifestations of IgG4RD are salivary glands, lacrimal glands and pancreas involvement. The common chief complains are salivary glands and lacrimal glands enlargement. Accompanied by anaphylactic disease is a marked manifestation of this disease. Delayed diagnoses are not rare, though this situation has been improved since 2010, and more attention still should be paid to the disease.

Association between body mass index and health-related quality of life among Chinese elderly-evidence from a community-based study. BMC Public Health 2018; 18:1174. [PMID: 30314493 PMCID: PMC6186092 DOI: 10.1186/s12889-018-6086-1] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/02/2018] [Accepted: 10/02/2018] [Indexed: 01/12/2023] Open
Abstract
Background This study aimed to explore the effects of (body mass index) BMI on health related quality of life (HRQoL) among the elderly in Jiangsu, China. Methods A total of 10,257 community dwelling elderly (≥60 years old) were enrolled in a cross-sectional study. HRQoL was measured via the Eq-5d-3 L. Chi-square tests and one-way ANOVA analyses were used to compare the frequencies and scores of Eq-5d responses among different BMI groups (defined as “underweight”, “normal weight”, “overweight” and “obese”). Logistic regression analyses were conducted to examine the associations between BMI and HRQoL. Results Among the subjects, the proportion of “normal weight”, “underweight”, “overweight” and “obese” were 66.0, 8.3, 23.1, and 2.6%, respectively. The score of the Eq-5d index among total participants was 0.8036 and the Visual Analog Scale (VAS) score was 75.47. For both the responses frequency and scores of Eq-5d-3 L, there were significant differences among BMI groups (P < 0.001). The Logistic regression model showed that both in men and women, underweight elderly were more likely to suffer low HRQoL. The adjusted odds ratio (OR) with a 95% confidence interval (CI) for Eq-5d index/VAS was 2.03 (1.48, 2.79)/1.83 (1.34, 2.50) in men and 1.47(1.09,1.98)/1.52(1.20,1.91) in women. Overweight women more likely to have a low Eq-5d index, while overweight men were less likely to have a low Eq-5d VAS. Conclusion This study shows that underweight is an explicit risk factor of low HRQoL in both the male and female elderly, while the effect of overweight on low HRQoL varies slightly by gender.

Abstract
Objective Serum soluble CD25 (sCD25) could be used as a biomarker for disease activity in conditions associated with T-cell activation including various autoimmune diseases. This study aimed to explore the role of sCD25 as an indicator of disease activity and organ involvement in patients with systemic lupus erythematosus (SLE). Methods Serum samples were collected from 107 SLE patients and 92 age-matched healthy controls (HCs). All patients were followed up for 24 weeks, and sCD25 was measured by enzyme-linked immunosorbent assay. Clinical and laboratory data were recorded at baseline and then every two weeks until week 24. The Systemic Lupus Erythematosus Disease Activity Index-2000 (SLEDAI)-2K was adopted for assessing disease activity at all visits. Results Serum sCD25 levels were significantly increased in SLE patients compared to those in HCs ( p < 0.001). More patients in the high-sCD25 group had lupus nephritis, arthritis and vasculitis ( p = 0.010, p = 0.023 and p = 0.042, respectively). SLEDAI-2K, erythrocyte sedimentation rate, C-reactive protein and 24-hour urinary protein excretion were all associated with high levels of sCD25 ( p < 0.001, p = 0.002, p = 0.038 and p = 0.029, respectively). During the 24-week follow-up, more patients in the high-sCD25 group developed renal impairment (48% vs 6.2%, p = 0.005), and higher levels of sCD25 ( p = 0.033) were found at the time of onset of renal disease. Conclusions Serum sCD25 is a hallmark of disease activity and a predictor of renal disease in patients with SLE.

Abstract
OBJECTIVE To investigate the effect of myeloid-derived suppressor cells (MDSC) on pro-liferation of B lymphocytes in rheumatoid arthritis (RA) patients. METHODS The peripheral blood specimens were collected from 15 healthy adults and 38 RA patients who were divided into high disease activity group, medium activity group and low activity group according to their 28-joint disease activity score (DAS28). And the frequencies of MDSC were determined by flow cytometry. Then, B cells and MDSC were isolated by flow cytometry, respectively. B cells were labeled with carboxyfluorescein diacetate succinimidyl ester (CFSE) and then were co-cultured with MDSC in the presence of 3 mg/L anti-CD40 antibody and 10 mg/L CpG, for 3 days. Flow cytometry was performed to investigate the proliferation of B cells. RESULTS MDSC expanded markedly in high disease activity patients (7.13% ±2.17%) compared with medium (5.35%±1.36%) and low disease activity patients (4.72%±1.08%) or healthy controls (4.79%±1.02%) (P<0.05), and there were no statistical differences between healthy controls, medium and low disease activity RA (P>0.05). Moreover, the frequencies of MDSC were positively correlated with the DAS28 (P<0.05). After co-culture, MDSC significantly promoted B cell proliferation (P<0.01). CONCLUSION Our studies showed that MDSC expanded obviously in high disease activity RA patients, and their frequencies were positively correlated with the disease activities. Furthermore, MDSC could promote autologous B cell proliferation remarkably in vitro. These findings suggest that MDSC might be involved in RA pathogenesis through regulating B cell functions.

Abstract
OBJECTIVE To detect the levels of serum C-C chemokine ligand 19 (CCL19) in patients with systemic lupus erythematosus (SLE) and to evaluate the correlation between CCL19 expression and clinical features and laboratory parameters, trying to reveal the possible role of CCL19 in the pathogenesis of systemic lupus erythematosus. METHODS The levels of serum CCL19 were measured by enzyme linked immunosorbent assay (ELISA) in 90 patients with SLE and 30 healthy controls. These SLE patients included 75 patients who received treatment with glucocorticoids and disease-modifying anti-rheumatic drug (DMARD) and 15 patients without therapy. The frequencies of peripheral blood B cells and the B cell subsets were assessed in the patients with SLE by flow cytometry. The correlation between the clinical data, laboratory parameters, B cell subset frequencies and serum CCL19 levels were analyzed. Indepen-dent samples t test, paired t test, Pearson and Spearman correlation were used for statistical analyses. RESULTS The levels of CCL19 were markedly higher in the SLE patients without therapy and the patients with therapy than in the health controls[(596.25±409.19) ng/L and (422.90±395.84) ng/L vs. (157.79±125.23) ng/L, all P<0.001]. Serum CCL19 levels in the SLE patients without therapy were higher than the SLE patients who accepted glucocorticoids and DMARD treatment (P<0.05). The levels of serum CCL19 were positively correlated with anti-double stranded deoxyribonucleic acid (dsDNA), anti-nucleosome antibody (AnuA), IgA, IgG and IgM (r=0.38, P=0.007; r=0.332, P=0.029; r=0.519, P=0.007; r=0.461, P=0.018, respectively). Serum CCL19 levels in the SLE patients with photosensitivity, arthritis and secondary Sjögren's syndrome were higher than the SLE patients without photosensitivity, arthritis and secondary Sjögren's syndrome, respectively [(562.25±399.12) ng/L, (565.6±435.24) ng/L and (694.9±531.02) ng/L vs. (394.7±281.42) ng/L, (385.90±325.33) ng/L and (424.8±305.46) ng/L, all P<0.05]. The levels of serum CCL19 were positively correlated with the percentage of CD27-B cells and CD27-IgD-double-negative memory B cells (r=0.519, P=0.007; r=0.461, P=0.018, respectively). However, the levels of serum CCL19 were negatively correlated with the percentage of CD27+ memory B cells and CD27+IgD- switched memory B cells (r=-0.433, P=0.027; r=-0.616, P=0.001, respectively). CONCLUSION The increased serum CCL19 levels in SLE patients were associated with the production of autoantibodies, and CCL19 might be involved in the pathogenesis of SLE by disturbing the homeostasis of B cell subsets.

Abstract
Interstitial lung diseases (ILDs) are a diverse group of pulmonary disorders characterized by various patterns of inflammation and fibrosis in the interstitium of the lung. The underlying pathogenesis of ILDs is complex and associated with multiple rheumatologic conditions, such as systemic sclerosis, rheumatoid arthritis, pollymyositis and dermatomyositis, Sjögren's syndrome, and systemic lupus erythematosus. As the disease progresses, excessive pulmonary fibrosis impairs alveolar gas exchange and damages pulmonary function. The common methods to diagnose ILDs, such as clinical manifestations, pulmonary function test, and radiological examinations are not specific for ILDs and not able to diagnose ILDs at the early stage due to their low sensitivity. So, the easy way is important to diagnose ILDs. One important biomarker for ILDs is the high-molecular-weight glycoprotein, Krebs von den Lungen-6(KL-6). KL-6 encoded by the MUC1 gene is a mucin-like glycoprotein with high molecular weight and expressed predominantly on the cell surface of type II alveolar epithelial cells, and is detectable in the serum of patients with ILDs. We here report a case of ILDs associated with dermatomyositis and secondary Sjögren's syndrome. A 60-year-old woman was admitted to our hospital with the chief complaints of debilitation, dry mouth, dyspnea and astasia. ILDs associated with dermatomyositis and secondary Sjögren's syndrome was diagnosed clinically when the following criteria were satisfied: (1) development of dyspnea within 2 months of presentation, (2) pulmonary dispersion dysfunction, (3) bilateral infiltrative shadows on chest high resolution computed tomography (HRCT). She was treated with prednisone 50 mg/d prior to admission, but the result of therapy was not good. In our hospital she was treated with intravenous methylprednisolone and cyclophosphamide and oral hydroxychloroquine sulfate. Subsequently, her serum KL-6 levels gradually decreased after treatment, pulmonary diffuse function improved, and the improvement in the clinical manifestation and HRCT findings were observed. Nevertheless, the combination treatment of glucocorticoid and cyclophosphamide had contributed to the favourable outcomes. In conclusion, detection of serum KL-6 levels in ILDs associated with connective tissue diseases may be beneficial to making a definitive diagnosis, predicting the prognosis and monitoring the disease activity, which would be of great help in clinical practice. However, a well-designed clinical study with more patients and a longer follow-up period are required to arrive at a more conclusive judgment on the role of serum KL-6 in patients with ILDs.

Abstract
BACKGROUND Vascularized bone grafting was used in the treatment of osteonecrosis femoral head, which may directly influence the pathologic event of femoral head. OBJECTIVE This paper evaluates hemodynamic changes in osteonecrosis treatment of the femoral head (ONFH) with iliac bone flaps from the lateral femoral circumflex artery ascending branches via digital subtraction angiography. METHODS A total of 48 patients, (31 males and 17 females; 38 at stage II and 10 at stage III), were treated with iliac bone flaps pedicled with the ascending branch of the lateral femoral circumflex artery. DSA was performed on all 48 patients preoperatively and 6 months postoperatively, and 10 years postoperatively on 1 patient. RESULTS Six months after surgery, femoral head blood supplies were distinctly visualized in the selective DSA in 44 cases. 4 patients showed poor or failed vessel pedicle filling in the transplanted bone flaps. Total hip arthroplasty was performed on these 4 patients. DSA was conducted 10 years post-operation in 1 case; the subject showed normal blood supply of the femoral head. CONCLUSIONS The anatomical position of the ascending branch of the lateral femoral circumflex artery was constant. Digital subtraction angiography successfully examined hemodynamic changes in osteonecrosis treatment of the femoral head with vascularized bone flaps.

Abstract
Objective: To investigate the early intervention effects of metoprolol on connexin 43(Cx43) and phosphorylated Cx43 (p-Cx43) expression in rabbits with post myocardial infarction. Methods: A total of 24 adult male New Zealand white rabbits were divided into sham group (n=6), early treatment group(n=6), routine treatment group(n=6), and myocardial infarction group(n=6) with a randomized block design blocked by weight. Myocardial infarction was induced by left anterior descending coronary artery (LAD) ligation. Rabbits in sham group received similar surgical procedure without LAD ligation. Metoprolol (12.5 mg/kg dissolved in 2 ml distilled water) was applied to rabbits in early treatment group and routine treatment group per gavage immediately after recovery from anesthesia and at 24 hours after myocardial infarction, respectively, then treated daily for 40 days. Rabbits in sham group and myocardial infarction group received 2 ml distilled water per gavage daily for 40 days. Plasma lactate dehydrogenase (LDH) and creatine kinase (CK) level were detected by automatic biochemistry analyzer after 6 hours in all rabbits. Ventricular fibrillation threshold (VFT) was measured in vivo by bipolar pacing electrodes at 40 days. Cx43 and p-Cx43 distribution in ventricular tissue was detected by immunofluorescence analyses. Cx43 and p-Cx43 protein level in ventricular tissue was determined by Western blot. Results: (1) Plasma LDH ((851.7±85.9)U/L vs. (332.3±39.6)U/L, P<0.01) and CK ((1 192.7±105.3)U/L vs. (462.3±65.6)U/L, P<0.01) were significantly higher in myocardial infarction group than in sham group (both P<0.01). (2) VFT was significantly lower in myocardial infarction group than that in sham group ((470.0±91.0) beats per minute vs. (683.3±60.9) beats per minute, P<0.05), and VFT was significantly higher in early treatment group ((633.3±43.2) beats per minute) and routine treatment group ((645.0±30.8) beats per minute) than in the myocardial infarction group (both P<0.05). (3) Immunofluorescence analyses showed that Cx43 was mainly localized in the intercalated disk, which was perpendicular to the cell long axis with linear arrangement, and less lateral distribution in sham group, early treatment group and routine treatment group, which was significantly different as the case in the myocardial infarction group. The expression of p-Cx43 in myocardial infarction group was less than in sham group, which was significantly upregulated in in early treatment group and routine treatment group when compared with myocardial infarction group, and expression of p-Cx43 was significantly higher in early treatment group than in routine treatment group. (4)The p-Cx43/Cx43 ratio of protein was significantly lower in myocardial infarction group than in sham group (0.165±0.011 vs. 0.363±0.046, P<0.05), and significantly higher in early treatment group (0.720±0.063) and routine treatment group (0.364±0.030) than in myocardial infarction group (both P<0.05), and this ratio was significantly higher in early treatment group than in routine treatment group (P<0.05). Conclusion: Metoprolol treatment, especially the early metoprolol treatment (within 24 hours after LAD ligation), could significantly improve VFT by ameliorating the distribution and dephosphorylation of myocardial Cx43 in rabbits with experimental myocardial infarction.

Abstract
To evaluate the diagnosis value of antibodies to phosphatidylserine/prothrombin complex (aPS/PT) in patients with antiphospholipid syndrome (APS) and to determine the clinical features of APS patients with avidity of aPS/PT. Serum samples were collected from 108 APS patients. Sixty patients with pregnancy morbidity, 37 patients with thrombosis without a history of autoimmune diseases, and 89 healthy blood donors were included as the control group. The enzyme-linked immunosorbent assay (ELISA) test was performed to detect the concentration of aPS/PT, including IgG/M, IgG, and IgM forms, in the same serum sample. The chi-square (χ2) test was used to examine the difference of frequencies of antibodies in APS patients and patients with other diseases. Spearman correlation analysis was performed to investigate the relationship between aPS/PT and other clinical/laboratory parameters. aPS/PT was detectable in 68 (63.0%) of the 108 APS patients, 12 (13.2%) of the 91 disease control patients and 1 (1.1%) of the healthy controls. It was strongly correlated with the activity of lupus anticoagulant (LA) (OR 15.952, 95% CI 7.132-35.678; P < 0.001). The frequency of aPS/PT was 56.9% in anti-cardiolipid antibody (aCL)-negative, 60.5% anti-β2 glycoprotein I antibody (aβ2GPI)-negative, and 50.0% in both aCL and aβ2GPI negative APS patients. The IgG aPS/PT was significantly associated with arterial and venous thrombosis. The aPS/PT antibody could play an important role in the diagnosis of APS, especially in patients with negative aCL and aβ2GPI. It was positively related to thrombotic events in APS.

Abstract
OBJECTIVE To detect the expressions of T follicular helper (Tfh) subsets and T follicular helper effect memory (Tfhem) cells in circulation of patients with rheumatoid arthritis (RA), as well as to examine their roles in providing biomarkers for active RA. METHODS This study enrolled 41 patients with RA, who were navely-treated or had no application of hormone and disease-modifying anti-rheumatic drugs in recent 3 months, as well as 32 healthy controls. The percentages of Tfhem (CD4+CXCR5+CCR7lowPD1high) cells, Tfh (CD3+CD4+CXCR5+CD45RA-) subsets, Tfh1 (CXCR3+CCR6-Tfh),Tfh2 (CXCR3-CCR6-Tfh),and Tfh17 (CXCR3-CCR6+Tfh), were determined by flow cytometry of peripheral blood from the patients with RA and health controls. Serum levels of cytokines were detected by enzyme-linked immunosorbent (ELISA). The correlations of Tfhem/Tfh subsets with clinical indicators were analyzed. RESULTS The mean age of the patients was (56.1±14.0) years (range: 20-82 years), the mean disease duration was (8.2±8.1) years. There was no significant difference between the RA patients and the health controls with age and gender. As compared with the health control, the percentage of Tfhem was significantly increased in the peripheral blood of the RA patients (12.8%±5.7% vs. 8.7%±2.0%, P=0.001). Moreover, the increased Tfhem was correlated with the higher disease activity score in 28 joints (DAS28) and erythrocyte sedimentation rate (ESR), but not with other clinical indicators, such as C-reactive protein (CRP), anti-cyclic citrullinated peptide (CCP) antibodies, and rheumatoid factors (RF). In addition, the percentage of Tfh2 subset, but not Tfh1 or Tfh17, was significantly increased in the RA patients (3.002%±0.408% vs. 1.730%±0.160%, P=0.013). As compared with Tfh2-low group, serum levels of Ig (immunoglobulin) A [(3.045±0.261) g/L vs.(3.963±0.815) g/L, P=0.172], IgG [(13.800±0.862) g/L vs.(16.980±0.224) g/L, P=0.161], IgM [(1.135±0.083) g/L vs.(1.731±0.380) g/L, P=0.140], IL (interleukin)-4 [(2.322±0.214) ng/L vs.(3.994±0.751) ng/L, P=0.056] and IL-10[(1.898±0.105) ng/L vs. (3.125±0.880) ng/L, P=0.140] in Tfh2-high group tended to increase with no significant statistical difference. CONCLUSION Our data suggest that Tfhem is associated with disease activity and is a valuable marker for active RA. It also presents a potential pathogenesis in the development of RA and the target for future therapies. Meanwhile, the increased Tfh2 and associated cytokines might be involved in the development of RA.

Abstract
OBJECTIVE To explore the titer of glucose-6-phosphate isomerase (GPI) for early diagnosis of the outpatient with rheumatoid arthritis (RA) in real life, and to analyze its relationship with disease activity. METHODS In the study, 1 051 patients with arthritis were collected in the group who had joints tender and swelling, and 90 cases of healthy people as a control group. ELISA method was used to detect the serum level of GPI, and according to clinical features and laboratory test, all the patients including 525 RA patients, the other patients including osteoarthritis (OA), 134 cases of seronegative spine joint disease (SpA), 104 cases of systemic lupus erythematosus (SLE), 31 cases of primary Sjogren syndrome (pSS), 24 cases of gout arthritis (GA), 22 cases of other connective tissue diseases (including polymyalgia rheumatica, dermatomyositis, systemic sclerosis, adult Still disease) and 46 cases of other diseases (including 165 cases of osteoporosis, avascular necrosis of the femoral head, traumatic osteomyelitis, bone and joint disease, juvenile rheumatoid arthritis, tumor). The diagnostic values of GPI were assessed, and the differences between the GPI positive and negative groups of the RA patients in clinical characteristics, disease activity, severity and inflammatory index analyzed. RESULTS The positive rate of serum GPI in the patients with RA was 55.4%, contrasting to other autoimmune diseases (14.3%) and healthy controls (7.78%)(P<0.001). Compared with the OA and SpA patients, the RA group was increased more significantly, and the difference was statistically significant (P<0.001). The diagnostic value of GPI alone for RA was 0.39 mg/L, the sensitivity was 54.2%, and specificity was 87.3%. The positive rate of GPI in RF negative patients was 36.1%; the positive rate of GPI in anti-CCP antibody negative patients was 34.2%; the positive rate of GPI in RF and anti-CCP antibody negative patients was 24.1%. The level of GPI had positive correlation (P<0.05) with ESR, RF, anti-CCP antibody and HRF-IgG. CONCLUSION GPI is sensitive in the patients with RA; GPI positive is important in the diagnosis of RA with anti-CCP antibody and/or RF negative patients. The titer of GPI is related with disease activity of RA.

Abstract
OBJECTIVE To explore the significance of synovial fluid (SF) anti-cyclic citrullinated peptide (CCP) antibodies and anti-mutated citrullinated vimentin (MCV) antibodies in the diagnosis of serum negative rheumatoid arthritis (SNRA). METHODS Enzyme linked immunosorbent assay (ELISA) method was apllied in the detection of two groups of patients with knee joint fluid resistance against CCP antibody and antibody of MCV, the experimental group to SNRA patients, a total of 29 cases, and the control for patients with osteoarthritis (OA), a total of 28 cases, and clinical manifestations and laboratory parameters of the two groups were collected. RESULTS The positive rate of synovial fluid anti-CCP was 34.5% in the SNRA patients, which was significantly higher than 10.7% in the control patients(χ2=4.571, P<0.05). The positive rate of synovial fluid anti-MCV was 20.7% in the SNRA patients, which was significantly higher than 7.1% in the control patients(χ2=2.167, P>0.05). The SNRA patients of SF anti-CCP and anti-MCV positive had no significant difference from the SNRA patients of SF anti-CCP and anti-MCV negative in age, course and morning stiffness. The levels of erythrocyte sedimentation rate (ESR), C-reactive protein(CRP) and DAS28 scores in the SF anti-CCP positive patients were higher than those of the SF anti-CCP negative patients. The levels of ESR, CRP and DAS28 scores in the SF anti-MCV positive patients were higher than those of the SF anti-MCV negative patients, (all P<0.01). SF anti-CCP had correlation with ESR, CRP(r=0.567, P<0.01; r=0.664, P<0.01). SF anti-MCV had correlation with ESR, CRP (r=0.344, P<0.01; r=0.749, P<0.01). CONCLUSION SF anti-CCP and anti-MCV are helpful for the diagnosis of SNRA and judgement of SNRA activity.

[Clinical significance of serum C-C chemokine ligand 19 levels in patients with rheumatoid arthritis]. BEIJING DA XUE XUE BAO. YI XUE BAN = JOURNAL OF PEKING UNIVERSITY.

Abstract
OBJECTIVE To investigate the serum level of C-C chemokine ligand 19 (CCL19) and its clinical significance in rheumatoid arthritis. METHODS The serum CCL19 levels in both rheumatoid arthritis (RA) patients and health controls were detected by ELISA. The proportion of peripheral blood B cells and memory B cell subsets were also detected in some patients. Then the clinical and laboratory data of the patients were collected. The CCL19 levels in patients with different clinical features were analyzed. And the correlation between the clinical data, laboratory parameters, B cell subsets proportion and serum CCL19 levels were also analyzed. Independent samples t test, paired t test, Pearson and Spearman correlation were used for statistical analysis. RESULTS The levels of CCL19 was higher in the RA patients than the health controls (P<0.05). The serum CCL19 levels were decreased in the RA patients who accepted disease-modifying anti-rheumatic drugs (DMARDs) treatment for 6 months (P<0.001). Serum CCL19 levels were correlated with the titers of both rheumatoid factor (RF) and anti-cyclic citrullinated peptide (CCP) antibody (r=0.42, P=0.002; r=0.33, P=0.013), but not with erythrocyte sedimentation rate (ESR), C-reactive protein (CRP) and disease activity score in 28 joints (DAS28) (P>0.05). The levels of CCL19 were higher in the serum positive (RF and anti-CCP antibody) patients, but there were no differences between low and high disease activity RA, as well as early and non-early RA. There was no correlation between the serum CCL19 levels and the proportion of B cells as well as memory B subsets. All the proportion of peripheral blood CD27+ memory B cell subsets in RA was lower than the healthy controls, including CD27+IgD+, CD27+IgD- and CD27+ B cells. CONCLUSION The increased serum CCL19 levels in RA patients are associated with the activity of B cells, so CCL19 might predict whether the RA type is a B cell mediated RA, and specify the treatment directions for the rheumatologist.
