ABSTRACT

Objective: To evaluate the influence of duodenal stump reinforcing on the short-term complications after laparoscopic radical gastrectomy. Methods: A retrospective cohort study with propensity score matching (PSM) was conducted. Clinical data of 1204 patients with gastric cancer who underwent laparoscopic radical gastrectomy at the First Affiliated Hospital of Army Medical University from April 2009 to December 2018 were collected. The digestive tract reconstruction methods included Billroth II anastomosis, Roux-en-Y anastomosis and un-cut-Roux- en-Y anastomosis. A linear stapler was used to transected the stomach and the duodenum. Among 1204 patients, 838 were males and 366 were females with mean age of (57.0±16.0) years. Duodenal stump was reinforced in 792 cases (reinforcement group) and unreinforced in 412 cases (non-reinforcement group). There were significant differences in resection range and anastomotic methods between the two groups (both P<0.001). The two groups were matched by propensity score according to the ratio of 1∶1, and the reinforcement group was further divided into purse string group and non-purse string group. The primary outcome was short-term postoperative complications (within one month after operation). Complications with Clavien-Dindo grade ≥ III a were defined as severe complications, and the morbidity of complication between the reinforcement group and the non-reinforcement group, as well as between the purse string group and the non-purse string group was compared. Results: After PSM, 411 pairs were included in the reinforcement group and the non-reinforcement group, and there were no significant differences in baseline data between the two groups (all P>0.05). No perioperative death occurred in any patient.The short-term morbidity of postoperative complication was 7.4% (61/822), including 14 cases of anastomotic leakage (23.0%), 11 cases of abdominal hemorrhage (18.0%), 8 cases of duodenal stump leakage (13.1%), 2 cases of incision dehiscence (3.3%), 6 cases of incision infection (9.8%) and 20 cases of abdominal infection (32.8%). Short-term postoperative complications were found in 25 patients (6.1%) and 36 patients (8.8%) in the reinforcement group and the non-reinforcement group, respectively, without significant difference (χ2=2.142, P=0.143). Nineteen patients (2.3%) developed short-term severe complications (Clavien-Dindo grade ≥IIIa), while no significant difference in severe complications was found between the two groups (1.7% vs. 2.9%, χ2=1.347, P=0.246). Sub-group analysis showed that the morbidity of short-term postoperative complication of the purse string group was 2.6% (9/345), which was lower than 24.2% (16/66) of the non-purse string group (χ2=45.388, P<0.001). Conclusion: Conventional reinforcement of duodenal stump does not significantly reduce the incidence of duodenal stump leakage, so it is necessary to choose whether to reinforce the duodenal stump individually, and purse string suture should be the first choice when decided to reinforce.

ABSTRACT

Objective: To compare the clinical efficacy and quality of life between uncut Roux-en-Y and Billroth II with Braun anastomosis in laparoscopic distal gastrectomy for gastric cancer patients. Methods: A retrospective cohort study was performed. Inclusion criteria: (1) 18 to 75 years old; (2) gastric cancer proved by preoperative gastroscopy, CT and pathological results and tumor was suitable for D2 radical distal gastrectomy; (3) postoperative pathological diagnosis stage was T1-4aN0-3M0 (according to the AJCC-7th TNM tumor stage), and the margin was negative; (4) Eastern Cooperative Oncology Group (ECOG) physical status score <2 points, and American Association of Anesthesiologists (ASA) grade 1 to 3; (5) no mental illness; (6) able to answer questionnaires independently; (7) patients agreed to undergo laparoscopic distal gastrectomy and signed an informed consent. Exclusion criteria: (1) patients with severe chronic diseases and American Association of Anesthesiologists (ASA) grade >3; (2) patients with other malignant tumors; (3) patients suffered from serious mental diseases; (4) patients received neoadjuvant chemotherapy or immunotherapy. According to the above criteria, clinical data of 200 patients who underwent laparoscopic distal gastrectomy at the Department of General Surgery of the First Affiliated Hospital of Army Medical University from January 2016 to December 2019 were collected. Of the 200 patients, 108 underwent uncut Roux-en-Y anastomosis and 92 underwent Billroth II with Braun anastomosis. The general data, intraoperative and postoperative conditions, complications, and endoscopic evaluation 1 year after the surgery were compared. Besides, the quality of life of two groups was also compared using the Chinese version of the European Organization For Research and Treatment of Cancer (EORTC) quality of life questionnaire-Core 30 (QLQ-C30) and quality of life questionnaire-stomach 22 (QLQ-STO22). Results: There were no significant differences in baseline data between the two groups (all P>0.05). All the 200 patients successfully underwent laparoscopic distal gastrectomy without intraoperative complications, conversion to open surgery or perioperative death. There were no significant differences between two groups in operative time, intraoperative blood loss, postoperative complications, time to flatus, time to removal of gastric tube, time to liquid diet, time to removal of drainage tube or length of postoperative hospital stay (all P>0.05). Endoscopic evaluation was conducted 1 year after surgery. Compared to Billroth II with Braun group, the uncut Roux-en-Y group had a significantly lower incidences of gastric stasis [19.8% (17/86) vs. 37.0% (27/73), χ(2)=11.199, P=0.024], gastritis [11.6% (10/86) vs. 34.2% (25/73), χ(2)=20.892, P<0.001] and bile reflux [1.2% (1/86) vs. 28.8% (21/73), χ(2)=25.237, P<0.001], and the differences were statistically significant. The EORTC questionnaire was performed 1 year after surgery, there were no significant differences in the scores of QLQ-C30 scale between the two groups (all P>0.05), while the scores of QLQ-STO22 showed that, compared to the Billroth II with Braun group, the uncut Roux-en-Y group had a lower pain score (median: 8.3 vs. 16.7, Z=-2.342, P=0.019) and reflux score (median: 0 vs 5.6, Z=-2.284, P=0.022), and the differences were statistically significant (all P<0.05), indicating milder symptoms. Conclusion: The uncut Roux-en-Y anastomosis is safe and reliable in laparoscopic distal gastrectomy, which can reduce the incidences of gastric stasis, gastritis and bile reflux, and improve the quality of life of patients after surgery.

ABSTRACT

Dermatomyositis (DM) with positive anti-melanoma differentiation-associated gene 5 (MDA5) antibodies (MDA5+DM) is a kind of occasional and rare autoimmune disease. Due to the fact that MDA5+DM patients are prone to suffer from the rapid progressive interstitial lung disease (RP-ILD), and the mortality rate is extremely high (all-cause mortality at 6 months is almost 50%). In addition to lung disease, patients with MDA5+DM also suffering from the skin and muscle symptoms. The biomarkers represented by the anti-MDA5 antibody titer, ferritin, KL-6 level and CD4 +/CXCR4 +T cell percentage are considered to relate with MDA5+DM-ILD′s severity, activity evaluation, therapeutic effect monitoring, and prognosis prediction. The current therapeutic strategies for the disease is mainly combined with immunosuppression. This work systemly summarizes the diagnosis and treatment progress of anti-mda5 antibody-related dermatomyositis, which not only contributes to the research work of related disciplines, but also provides reference for clinical diagnosis and treatment.

ABSTRACT

Objective:To explore the impacts of postoperative radiotherapy on long-term survival of the patients with resectable locally advanced (T 3-4and/or N +) biliary tract cancers (BTCs) and to analyze the prognostic factors. Methods:The patients with locally advanced gallbladder cancer ( n=1 922) and the patients with extrahepatic biliary duct cancer ( n=3 408) who received surgical resection during 2006-2016 were selected from the Surveillance, Epidemiology, and End Result (SEER) database. They were grouped according to different treatment schemes (only surgery and surgery + radiation). The propensity score matching (PSM) method was employed to adjust the differences in baseline prognostic characteristics between patients who received only surgery and those treated with surgery+ radiation. The role of the two treatment schemes on the survival of the patients was analyzed using the Kaplan-Meier method and the prognosis factors were assessed using the Cox regression. Results:The 1 174 patients with gallbladder cancers and the 2 144 patients with extrahepatic biliary duct cancer were respectively matched according to propensity scores. The postoperative radiotherapy showed a significant advantage in 5-year cancer-specific survival (CSS) compared to only surgery for both the patients with gallbladder cancer ( χ2=35.73, P< 0.001) and those with extrahepatic biliary duct cancer ( χ2=9.878, P=0.002). After adjusting related covariates, independent prognostic factors for all the patients included pathological grading, T status, N status, treatment pattern, and age. For the patients with extrahepatic biliary duct cancer, independent prognostic factors also included race and year of diagnosis. The benefits of postoperative radiotherapy were observed in various clinicopathologic characteristics except for the patients with T 1-2 gallbladder cancer and the extrahepatic biliary duct cancer patients with a pathological grade of Ⅰ-Ⅱ and N 0 status or with age ≥ 70. Conclusions:Long-term survival benefits can be gained through postoperative radiotherapy for the patients with resectable locally advanced (T 3-4 and/or N+ ) BTCs. However, adjuvant radiation should be cautiously adopted for the patients with T 1-2 gallbladder cancer and the extrahepatic biliary duct cancer patients with a pathological grade of I-Ⅱ and N 0 status or with age ≥70.

ABSTRACT

Objective:To determine the characteristics of hospitalized newly diagnosed systemic lupus erythematosus (SLE) patients with high disease activity, and identify the risk factors.Methods:Data from 194 newly diagnosed SLE patients at Shanghai Renji Hospital between May 2013 and December 2018 were collected retrospectively. All patients were followed up for 1 year or until death. Patients' demographic, clinical, and laboratory characteristics on admission and medication history were retrospectively collected as baseline data. Patients were divided into two groups, lupus patients with infection (51 cases) and lupus patients without infection (143 cases). The method of univariate analysis of data depended on the data distribution type. Variables that suggested association in the univariate analysis ( P<0.05) were entered into Cox regression model. Results:Among 194 patients with newly diagnosed SLE, 21 cases (11%) died and 51 cases (26%) were infected during 1-year follow-up. Regarding the infection site, 34 cases (67%) had lung infection, 9 cases (18%) had central nervous system infection and 9 cases (18%) had blood stream infection. Common bacteria were identified in 19 cases (45%), followed by fungal infection in 18 cases (43%) and mycobacterium infection in 7 cases (17%). Among the 51 patients with infection, 38 patients (75%) had infection within the first 3 months after diagnosis, and mortality in this group was significantly higher than that in the uninfected group (39%, 15/38 vs 2%, 3/143 , P<0.01). Comparing baseline parameters between patients with 3-month infection and without, significant differences ( P<0.05) were detected in age (≥40 years), systemic lupus erythematosus disease activity index (SLEDAI) score (>10 points), Systemic Lupus International Collaborating Clinic (SLICC)/American College of Rheumatology(ACR) systemic lupus erythematosus damage index (SDI) (≥1 point), pericardial effusion, nephritis, gastrointestinal vasculitis, diabetes, lymphocyte count <0.8×10 9/L platelet count <100×10 9/L, serum creatinine >104 mmol/L and serum globulin level <20 g/L. Finally, clinically meaningful candidate predictors were included in the Cox regression model and it showed that lymphocyte count <0.8×10 9/L, nephritis and gastrointestinal vasculitis were independently predictive for 3-month infection in new-onset lupus patients. Conclusion:Understanding disease spectrums and risk factors of infection in newly diagnosed SLE patients will help clinicians to manage those patients with infection effectively to achieve favorable prognosis.

ABSTRACT

Objective:To evaluate the association between the efficacy and safety of metformin and the influence of variants in SLC47A1 rs2289669 G>A polymorphism in the treatment of systemic lupus erythematosus (SLE).Methods:A multicenter, randomized, double-blind, placebo-controlled trial was conducted. Patients were consented at enrollment for blood donation for genotyping, and their peripheral blood were used to detect the distribution frequency of SLC47A1 mutations. The major or mild/moderate flares defined by modified safety lupus erythematosus national assessment (SELENA)-systemic lupus erythematosus disease activity index (SLEDAI) Flare Index (SFI) and adverse events were recorded at 12 months of follow-up. The correlation between efficacy/safety and genotype was analyzed. Student's t test and χ2 test was used to assess the continuous variables and categorical variables. Results:Between May 24, 2016, and Dec 13, 2017, a total of 31 patients in the metformin group and 35 in the placebo group were detected. There were no statistical significant differences in the clinical manifestations, SELENA-SLEDAI scores, and therapy of the participants at baseline. There was no significant difference in the frequency of AA genotype, GA genotype, and GG genotype of SLC47A1 rs2289669 distribution between the metformin group and the placebo group. In the metformin group, patients who flared had a lower frequency of A alleles than those non-flared [25%(4/16) vs 61%(28/46), χ2=6.116, P=0.019 8]; the flare rate was significantly lower in patients with AA genotype than in GG genotype [0%(0/8) vs 57%(4/7), χ2=6.234, P=0.012 5]. The infection rate was lower in the metformin group than that in the placebo group [38%(12/31) vs 69%(24/35), χ2=5.913, P=0.015 0], but there was no significant difference among different genotypes in the metformin group. Compared to GG geno-type, AA genotype showed a trend of decrease in infection rate[38%(3/8) vs 72%(5/7), χ2=1.727, P=0.188 8]. Conclusion:Metformin has a favorable safety profile and may reduce the frequency of flares in SLE patients with low-grade lupus disease activity. The metformin therapeutic efficacy in SLE is relevant to the SLC47A1 gene polymorphism. Patients of the AA genotype may benefit most from metformin than those of the GG and GA genotypes.

ABSTRACT

Objective In 2016,European League Against Rheumatism (EULAR)/American College of Rheumatology (ACR)/Pediatric rheumatology international trials organization (PRINTO) released the classification criteria for macrophage activation syndrome (MAS) in patients with systemic juvenile idiopathic arthritis (sJIA).Due to the similarities of both clinical manifestations and pathogenesis between adult-onset Still dsease (AOSD) and sJIA,we hope to evaluate the 2016 sJIA-AMS classification in AOSD patients.Methods A total of 169 AOSD patients who were hospitalized in Renji Hospital were enrolled in this study.AOSD patients were divided into AOSD with MAS and AOSD without MAS,using the 2016 sJIA-MAS criteria.The data of the two groups were analyzed by Chi-square test,Mann-Whitney U test and binary Logistic analysis,and factors influencing the prognosis of patients were analyzed by Kaplan-Meier and COX regression analysis.Results According to sJIA-MAS criteria,56 AOSD patients with MAS were identified in all the 169 AOSD cases.In AOSD patients,the incidence of splenomegaly and pericarditis/myocarditis was significantly higher in patients with MAS than in AOSD without MAS [42.9% vs 14.2%,OR(95%CI)=4.50(2.13,9.51),P<0.01;10.7% vs 0.9%,OR(95%CI)=13.21 (1.56,113.57),P<0.01],also the incidence of liver dysfunction was higher in AOSD with MAS [67.8% vs 11.5%,OR(95%CI)=0.18(7.26,36.33),P<0.01].Among the AOSD with MAS,62.5%(35/56) of these patients received large-dose glucocorticoid therapy,5.4% (3/56) received the glucocorticoid pulse therapy,48.2%(27/56) were treated with IVIG,and 26.8%(15/56) were treated with calcium phosphatase inhibitors.The mortality rates of AOSD with MAS was 8.9%(5/56),which was significantly higher than 1.8%(2/113) (OR =5.44,P<0.05),the mortality rate of the AOSD without MAS.Patients who fulfilled the sJIA-MAS criteria suggested poor prognosis (OR=0.041,P=5.44),and the platelet count ≤ 181× 109/L (OR=12.17,P=0.002),alanine aminotransferase >48 U/L (OR=9.43,P=9.040) were also highly suggestive of poor prognosis.Conclusion The 2016 sJIA-MAS classification criteria are particularly valuable for early recognization of MAS in AOSD patients,and convenient to use.AOSD patients fulfilled sJIA-MAS criteria are more severe,and require larger doses of glucocorticoid and more immunosuppression therapy compared to patients without MAS,and the prognosis of these patients is also poor.

ABSTRACT

Objective To compare the performance of four commercial anti-dsDNA antibody assays,i.e,BioPlex 2200 (BioPlex),Farr radioimmunoassay (Farr),MESACUP DNA-Ⅱ TEST ds [MBL-enzyme linked immunosorbent assay (ELISA)] and Anti-dsDNA-NcX ELISA (IgG) (EURO-ELISA),Antoantibodies Profile Assay Kit (HOB-Chemiluminescent Immunoassay) in disease activity assessment of systemic lupus erythematosus (SLE).Methods SLE patients (n=119) as well as healthy controls (n=200) and disease controls (n=100) were recruited and their serum anti-dsDNA antibodies were detected by BioPlex,Farr,MBL-ELISA,EURO-ELISA,and a standard Crithidia luciliae indirect immunofluorescence test (CLIFT).The consistency between above four methods to CLIFT was analyzed.The correlation of anti-dsDNA antibody level of these four methods to SLE disease activity was assessed.All data analyses were performed with Statistical product and service solutions (SPSS) 16.0 (SPSS.Inc) and GraphPad Prism 4.0.3 (GraphPad).Unless otherwise specified,all data in this study were expressed as mean±standard deviation.Cut-off values of the anti-dsDNA quantification methods were set by the manufacturers.Chi square and kappa coefficients were adopted to assess the agreement determination and correlation analysis between anti-dsDNA level and SLE disease activity (SLEDAI).Receiver-operator characteristic (ROC) curve analysis was used to compare the specificity and sensitivity of the anti-dsDNA assays.Student's t test was adopted for the comparison of anti-dsDNA levels by different methods between SLE and SLE+LN groups.A p value small than 0.05 was considered statistically significant.Results Using cut-off values set by the manufacturers,BioPlex demonstrated the highest overall agreement with CLIFT,while MBL-ELISA and EURO-ELISA showed the highest positive agreement with CLIFT.Disease activity correlation analysis showed that SLEDAI score correlated poorly with anti-dsDNA level in Farr assay,but strongly with the other three assays.Bioplex had a better performance in terms of SLE activity index corelation (r=0.297 6,P=0.001 2).Moreover,anti-dsDNA level differed in SLE patients with renal lupus nephritis in BioPlex assay (P=0.026 8),but not in the other assays.In ROC curve analysis,BioPlex showed the largest area under the curve (AUC) over other assays.Conclusion Bio Plex assay has better sensitivity and specificity than Farr,MBL-ELISA and EURO-ELISA and correlates well with SLE disease activity.

ABSTRACT

Objective Renal vascular injury,especially thrombotic microangiopathy (TMA),is an important prognostic factors in pat.ients with lupus nephritis.TMA is most likely to be associated with proliferative lupus nephritis.This single-center retrospective study was conducted in order to explore the characteristics and prognosis of patients with TMA associated with proliferative lupus nephritis.Methods From January 2013 to June 2016,146 hospitalized patients with lupus nephritis underwent renal biopsy in the Department of Rheumatology,South Campus,Ren Ji Hospital,of which 108 were proliferative nephritis including 32 with TMA and 76 without TMA.All the clinical records were collected.All data were analyzed by Graphpad 5.0 or SPSS 22.0 statistical software analysis.Nonparametric test,t test and Fisher test were used for comparison between the two groups.Predictors were analyzed by multiple factors regression analysis,survival curve was analyzed by Kaplan-Meire method.Results Patients with TMA were found to have higher levels of creatinine (Cr) [93.5 (69.0,179.8) μmol/L vs 73.0 (56.3,116.3) μmol/L,U=833,P=0.010 1],B-type brain natriuretic peptide (BNP) [177(93.2,619) pg/ml vs 87.5(28.5,255) pg/ml,U=765,P=0.004 6],24-hour urinary protein [4.98 (1.99,7.62) g vs 2.83 (1.71,4.38) g,U=875,P=0.022] and highersystemic lupus erythematosus disease activity index (SLEDAI) [16(13.25,18) vs 12(10.25,14),U=559,P<0.000 1],as well as lower complement [C3:(0.37±0.15) g/L vs (0.52±0.20) g/L,t=3.713,P=0.000 3;C4:0.056 (0.035,0.140) g/L vs 0.088(0.053,0.167) g/L,U=912,P=0.047 9],albumin (Alb) [(24±6) g/L vs (28±6) g/L,t=3.416,P=0.000 9] and hemoglobin (Hb) [(88±19) g/L vs (99±21) g/L,t=2.627,P=0.015 7].They were more prone to hypertension [(24/32,75%) vs (35/76,46%),x2=7.613,P=0.006 4],had less glomerular sclerosis [0(0,0.038)% vs 7(0,17)%,U=848,P=0.007 7] and higher acute score [16(14.25,19.75) vs 13(10,15),U=612,P<0.000 1];while these patients received higher doses of corticosteroid therapy,and more patients were treated with cyclophosphamide for induction therapy.Multivariate regression analysis showed that Cr (OR =1.008,P=0.033) and SLEDAI (OR =1.272,P=0.003) scores might be predictors of TMA in patients with proliferative lupus nephritis.During follow up,6 and 2 patientsin two groups progressed to end-stage renal disease (ESRD),respectively (P=0.010 4).Univariate analysisfound that patients progressed to ESRD were more likely to have TMA[(6/8,75%) vs (23/85,27%),x2=7.831,P=0.010 4],and had more crescents[54.5(12,83.5)% vs 20(6,41)%,U=183,P=0.032].Higher activity indices (AI) [(20±6) vs (14±4),t=3.489,P=0.000 7],Cr [286(214.5,395) μmol/L vs 76(59,115.5) μmol/L,U=19,P<0.000 1] and BNP [456(192.3,1 060) vs 110(45.38,275.5),U=116.5,P=0.002 4],as well as lower Hb [(71±12) vs (97±19),t=3.776,P=0.000 3] and platelets (PLT) [(130±71)×109/L vs (196±76)×109/L,t=2.399,P=0.018 5] were observed in these patients.Conclusion This study has shown that patients with proliferative lupus nephritis with renal TMA have a higher level of Cr and more active disease state,requiring more aggressive immunosuppressive therapy and more likely to progress to ESRD.So renal TMA may be one of the risk factors of renal survival in these patients.

ABSTRACT

Objective To investigate the prevalence of uveitis associated with axial spondyloarthritis (ax-SpA), and analyze the features of patients with ax-SpA accompanying uveitis. Methods Two hundred and eighteen patients with ax-SpA were recruited. The differences in demographic factors, clinical features, the use of drugs and the quality of life were compared between uveitis group and non-uveitis group by using t-tests andχ2 tests. Results The prevalence of uveitis associated with ax-SpA was 24.3%. Uveitis group had longer disease duration [(156±140) month] compared to the non-uveitis group [(84±98) month] (t=-3.473, P=0.001), longer duration from disease onset to diagnosis [(90±105) month] compared to non-uveitis group [(47±65) month (t=-2.818, P=0.006), longer duration from first visit to diagnosis [(67±97) month] compared to non-uveitis group [(34 ±55) month] (t=-2.366, P=0.021). Patients with uveitis had higher rate of positive HLA-B27 (97.7%) compared to non-uveitis group (74.2%) (t=5.822, P=0.016), higher score of bath ankylosing spondylitis metrology index (BASMI) (3.3±2.0) compared to non-uveitis group (2.4±1.9) (t=-3.141, P=0.002), higher usage rate of biological agent (64.2%) compared to non-uveitis group (t=4.907, P=0.027). Conclusion In patients with acute anterior uveitis, the history should be carefully collected and HLA-B27 should be examined in order to make early diagnosis and treatment of ax-SpA, reducing uveitis flares and functional impairment.

ABSTRACT

Objective To investigate autoantibody against endothelin receptor type A (ENRA-Ab) in patients with systemic lupus erythematosus associated pulmonary arterial hypertension (SLE-PAH).The possibility of autoantibody-mediated pathogenesis in the development of SLE-PAH has also been explored.Methods ENRA-Ab in the serum of SLE-PAH and controls were detected by using a human ETRA epitope peptide-based ELISA.The clinical relevance of ENRA-Ab in SLE-PAH was analyzed.Proliferation of vascular smooth muscle cells (SMCs) and permeability of endothelial cells in vitro under the stimulation of polyclonal ENRA-Ab IgG were assessed.The expressions of PAH-related markers, i.e., 5-HTT, PDGFR-b, VEGF-A and PDGF-B were measured by qPCR.The effect of ENRA-Ab in vivo was also determined in a suboptimaldose monocrotaline-induced model with the assessment of right ventricle hypertrophy index and pathology parameters.Independent t-test, Tukey-Kramer test of variance analysis and Pearson' s correlation analysis were used for statistical analysis.Results ENRA-Abs was presented in a higher occurrence in SLE-PAH (35/85,41%) compared with controls (0/60;0, 13/80, 16%).There was a significant correlation between ENRA-Ab and echocardiograph estimated pulmonary arterial systolic pressure (r=0.392, P=0.002) in SLE-PAH.ENRA-Ab could promote SMCs proliferation, disrupt endothelial barrier and up-regulate PAH-related markers expression,which could be blocked in the presence of ETR antagonist.ENRA-Ab aggravated right ventricle hypertrophy and vascular remodeling in vivo.Conclusion ENRA-Ab is a new biomarker, in SLE-PAH, which may mediate PAH development in SLE.

ABSTRACT

Objective To correlate the neutrophil extracellular trap (NET) mitochondrial DNA (mtDNA) and anti-mtDNA antibodies (Abs) with disease activity and clinical features in systemic lupus erythematosus (SLE) patients.Methods We enrolled 102 SLE patients,rheumatoid arthritis (RA) patients (n=30) and healthy donors as controls (n=40).NET were generated from phorbol 12-myristate 13-acetate (PMA)-stimulated peripheral neutrophils.mtDNA levels and the transcriptional levels of five interferon inducible genes(IFIGs)(OAS-1,Mx-1,Ly6e,IFIT1 and IFIT4) were measured by quantitative PCR.Interferon scores (IFN scores) were calculated.Anti-mtDNA Abs were detected by enzyme-linked immunosorbent assay.Spearman's correlation analysis,t test andx2 test were used for statistical analysis.Results mtDNA release by netting neutrophils was greatly enhanced in SLE patients (1 088 000 ±1 133 000) compared with healthy controls (465 900±447 200)(t=2.617,P<0.01) and significantly correlated with IFN scores (r=0.460 6,P<0.01).NETs mtDNA in moderate active group (728 300±1 003 000) and severe active group (1 093 000±946 500) were significantly higher than the mild active group (159 500±155 100) (t=2.240,P<0.05,t=3.894,P<0.01).Forty-one percent of SLE patients were positive for anti-mtDNA Abs(1.28±0.68),while none of the healthy donors (0.70±0.31) (P<0.01) and RA controls (0.59±0.18)(P<0.01) displayed a positive serology response to mtDNA.Addition-ally,the titers of anti-mtDNA Abs were also associated with IFN scores (r=0.292 8,P<0.05).Anti-mtDNA Abs in moderate active group (1.3±-0.6) and severe active group(1.4±0.7)were significantly higher than the mild active group (0.7±0.4) (t=3.154,3.538,all P<0.01).The levels of anti-mtDNA Abs significantly correlated with classic an-ti-dsDNA Abs titers measured by Farr assay (r=0.542 9,P<0.001) and were associated with LN (x2=8.644,P<0.01).Conclusion mtDNA in NET and anti-mtDNA Abs serve as new biomarkers for disease activity and renal involvement in SLE patients.

ABSTRACT

Patients with early cataract may have normal visual acuity ( VA ) but complain that they have problems in driving at night, like seeing things through a veil. This phenomenon is defined as disability glare which maybe caused by growing stray light. Patients with intraocular lens following cataract surgery may complain about glare, halos and shadows in visual field, which are also resulted from dysphotopia. Disability glare is the VA loss due to disturbing luminance in visual field. ln other words, it's the retinal contrast sensitivity reduction because of the straylight. This article contains the consensus and new progress of disability glare. lt provides solutions according to its effect factors and offers clues for further study.

ABSTRACT

Objective To investigate the quality of life and sexual function of cervical cancer patients following radical hysterectomy (RH) and vaginal extension.Methods Case-control and questionnaire-based method was employed in this study.Thirty-one patients of early-stage (Ⅰ b1-Ⅰ b2) cervical cancer who had undergone vaginal extension following classic RH in Peking Union Medical College Hospital from December 2008 to September 2012 were included in study group,while 28 patients with matching factors and RH only during the same period were allocated to control group.There was no significant difference between two groups in terms of clinical and demographic variables including age at diagnosis,tumor stage and follow-up time (P>0.05).Patients were assessed retrospectively by validated selfreported questionnaires the European Organization for Research and Treatment of Cancer Cervix Cancer Module Questionnaire (EORTC QLQ-CX24) mainly for quality of life and sexual function for cervical cancer patients; the Sexual Function and Vaginal Changes Questionnaire (SVQ) further investigates sexual function and vaginal changes of patients with gynecologic malignancy at least 6 months after treatment.Results Vaginal length acquired by pelvic examination by gynecologic oncologists during follow-up visits was (10.0±1.3) cm and (5.9± 1.0) cm in study group and control group respectively (P=0.000).Sixty-eight percent (21/31) of cases in study group and 64% (18/28) of cases in control group had resumed sexual activity at the time of interview,and the time interval between treatment and regular sexual activity was mean 6 months (range 3-20 months) and mean 5 months (range 1-12 months) in study and control group respectively,in which there was not statistical significance (P>0.05).No difference was observed regarding pelvic floor symptoms (P>0.05) while difficulty emptying bladder,incomplete emptying and constipation were most commonly reported.Both group presented with hypoactive sexual desire disorder [88% (52/59)],orgasm dysfunction [72%(28/39)] and low enjoyment or relaxation after sex [51%(20/39)],which was not statistically significant (P>0.05).Reduced vagina size and shorter vagina was more prominent in control group (12/18) than that in study group [19% (4/21)] with statistical significance (P<0.05),while no difference in sexual desire,vaginal lubrication,dyspareunia and sexual enjoyment (P>0.05).Conclusions Patients with peritoneovaginoplasty following RH had much longer vagina and less self-perceived short vagina.Vaginal extension following RH does not worsen the pelvic floor symptoms.

ABSTRACT

Objective To investigate the effects of long-term low-dose radiation (LDR) of γ-rays on the proliferation and radiosensitivity of human lymphoblast cells HMy2.CIR (HMy) and to elucidate the underlying mechanism.Methods HMy cells were divided into control group and long-term LDR group.For the long-term LDR treatment,HMy cells were fractionally exposed to a low dose of γ-rays,which could enhance cell proliferation,3 times per week for 4 weeks.After the long-term LDR exposure,part of the control and long-term LDR exposed cells were further irradiated with a challenging dose (2 Gy) of γ-rays.Then cell proliferation and radiosensitivity were assayed by CCK-8 kit,cell apoptosis,and γ-H2AX formation was measured by flow cytometry.Gene expressions of cyclinD1,PCNA,bcl-2 and bax were detected by RT-PCR.Results The long-term LDR significantly increased cell proliferation (t =9.607,P < 0.01) accompanied with up-regulation of cell cycle regulation gene cyclinD1 (t =6.869,P < 0.01),proliferation regulation gene PCNA (proliferating cell nuclear antigen) (t =9.229,P < 0.01) and bcl-2 gene (t =2.662,P < 0.05),but decreased the expression of pro-apoptotic gene bax (t =19.908,P <0.01) in HMy cells.Compared to untreated cells,the long-term LDR decreased cell radiosensitivity (t =8.896,P < 0.01),including apoptosis induction (t =4.762,P < 0.01) and γ-H2AX formation (t =10.264,P<0.01).Conclusions The long-term LDR promoted cell proliferation by up-regulating cell cycle related genes,while it reduced the radiosensitivity of HMy cells with acquisition of apoptotic resistance.

ABSTRACT

ObjectiveInvasive fungal infection(IFI) can be a lethal complication in patients with diffuse connective tissue diseases(DCTD).The aim of this study was to determine the characteristics of hospitalized DCTD patients with IFI,and identify the risk factors.MethodsData from 33 DCTD in patients with IFI at Shanghai Renji Hospital between Jan 2007 and Jan 2011 were collected retrospectively.DCTD patients with either active M.tuberculosis (n=33) or other bacterial infections (n=34) at the same period were taken as controls.Systemic lupus erythematosus (SLE) inpatients with IFI (n=11 ) from Jan 2002 to Dec 2006 were also considered as a historical control group.The method of univariate analysis of data depended on the data distribution type.Variables that suggested association in the univariate analysis P<0.1 were entered into a stepwise logistic regression model.ResultsThe leading underlying diseases of DCTD with IFI were SLE(n=18,55%),systemic vasculitis(n=4,12%),and inflammatory myopathy(n=4,12%).The most frequent pathogen was Candida spp(n=13,39% ),followed by Cryptococcus neoformans(n=10,30% ),and Aspergillus (n=3,9%).The infection locations included lung (n=19,58%),central nervous system (n=9,27% ),and disseminated IFI(n=4,12% ).Six patients(18%) died from IFI.Compared with non-IFI infections,patients with IFI infection had a shorter duration of underlying disease and were exposed to high doses of prednisolone prior to infection.More patients with IFI infection had elevated alanine aminotransferase,higher fasting glucose and lower C-reactive protein levels when compared to patients with non-IFI infections.Compared with the two historical SLE-IFI groups, the short-term survival improved in lupus patients complicated with IFI infection over time(64% vs 83%).ConclusionUnderstanding disease spectrums and risk factors of IFI in DCTD,along with advances in antifungal treatment,will help clinicians to manage those patients with invasive fungal infection effectively to achieve favourable prognosis.
