Objective: To invesgate the situation of psychological abuse and neglect among juveniles with generalized anxiety disorder(GAD) and explore the characteristics of behavior and self-concept in psychological abused/neglected juveniles with GAD.Methods: A sampling survey was made in 9495 juveniles(5~17) from six regions of Hunan Province.After using the two-stage epidemiologic research method,409 children including 206 normal controls,99 GAD without abuse/neglect and 104 GAD with abuse/neglect,completed CPANS,CSCS and their parents completed CBCL.Results: There were significantly higher rates of psychological abuse or neglect in the GAD group than the normal controls;the factor scores of juveniles with GAD were significantly higher than those with no mental disorders in all six aspects in CPANS(P=0.000),higher scores of internalizing and externalizing behaviors characterized the subgroup of juveniles with both GAD and abuse history compared with the subgroup with GAD without such history,and the scores including total score,behavior,anxiety,gregariousness and happiness factors(P=0.000),of the subgroup of juveniles with GAD and abuse histories were significantly lower than the GAD subgroup without abuse or neglect.Conclusion: Psychological abuse and neglect are more prevalent and severe in juveniles with GAD than in normal ones;when psychological abuse/neglect co-occurs with GAD,juveniles’ behavior problems are even greater and their level of self-concept are much lower.

Objective To investigate the ultrasound features of gouty joints during acute and past attacks. Methods Clinical data and ultrasound features of joints during the acute and past attacks of gouty patients who were experiencing an acute attack were collected. The differences of ultrasound features between two episodes, as well as the relationship with clinical characteristics were analyzed. Results Sixty-four patients were enrolled with 21 (33%) patients at their first attack. The first metatarsophalangeal (MTP1) joints were most frequently involved, meanwhile, 9.4% patients had two or more joints attacked during one episode. The most prevalent feature was synovitis at the acute phase, followed by double contour (DC) sign (18 cases, 28%), bone erosion (12 cases, 19%) and tophi (10 cases, 16%), while 23 patients had two or more pathological changes. Whereas, the DC sign was found most in previously attacked joints (10 cases, 33%), followed by tophi (8 cases, 27%), bone erosion (7 cases, 23%) and synovitis (4 cases, 13.3%). No positive pathological changes were found in asymptomatic joints. Synovitis was more common in joints during their acute attacks (80% vs 13%, χ2=20.475, P<0.01), however, DC sign and tophi were more common in previous attacked joints (10% vs 33% and 0 vs 27%, χ2=3.892, 6.642, P<0.05, respectively). Both the DC sign and tophi were positively correlated with the disease duration. Conclusion Synovitis is the most prevalent feature in gouty joints during acute episodes; even bone erosion can be found at the first attack. The DC sign, tophi and bone erosion are common in past attacked joints. The prevalence of both DC sign and tophi are increased along with disease durations. Subclinical synovitis can be detected in a small past of joints which are not at acute attack.

Objective:To investigate the frequency of metabolic syndrome (MS) in patients with psoriatic arthritis (PsA) and further analyze the correlation of MS and its components with clinical features of PsA.Methods:Data including demographics, clinical manifestations, laboratory tests, MS-associated features (height, weight, waist circumference, blood pressure, serum lipid spectrum, and so on) and history of complications (hypertension, diabetes mellitus, atherosclerosis, coronary heart disease, and cerebral vascular disease) were collected from PsA patients in our hospital from Jan 2017 to Sep 2019. The frequency of MS in PsA patients was calculated and the association between PsA clinical manifestations and MS as well as its components was investigated.Results:One hundred and sixty-two PsA patients who fulfilled the Classification Criteria for Psoriatic Arthritis (CASPAR) were recruited. Hypertension was identified in 36 (22.2%) patients, diabetes mellitus in 28(17.2%) patients, coronary heart disease in 11(6.7%) patients, and cerebral vascular disease in 7 (4.3%) patients. Based on the criteria of the International Diabetes Federation (IDF), 58(35.8%) patients were diagnosed as MS. Compared with MS-free patients, patients with MS, hypertension or diabetes mellitus were older [(54±10 vs 44±13; 56±11 vs 45±12; 54±11 vs 44±13, respectively, t=5.058 , 4.450, 5.150, P<0.01 for all], with higher disease activity [DAPSA scores 16.75(11.25, 26.7) vs 8.8(4.8, 16.4), 16.3(9.6, 27.8) vs 10.0 (5.1, 18.0), 14.4 (9, 25.7) vs 9.5 (5, 17.7), Z=4.539 , 3.046, 3.063, P<0.01]. There was a positive correlation between the sum of components of MS and DAPSA score ( r=0.27 , P<0.01), but multiple linear regression showed no correlation between each component with DAPSA score ( P>0.05) except for hypertension ( P<0.01, standard coefficient=0.334) and elevated fasting blood glucose ( P=0.023, standard coefficient=0.247). PsA patients with hypertension had higher ESR [16.5 (9.5, 34.25) mm/1 h vs 10 (5, 24.5) mm/1 h, Z=2.127, P=0.012]. CRP level was higher in patients with dyslipidemia [5.6(2.1, 17.8) mg/L vs 3.7(1.5, 6.5) mg/L, Z=2.543, P<0.01]. Prevalence of inflammatory back pain was also higher in dyslipidemia patients (41.3% vs 22.4%, χ2=5.901, P=0.016). DAPSA score was higher in dyslipidemia patients (14.1 vs9.9, P=0.031). Conclusion:MS and its components are not rare comorbidities in PsA patients. PsA patients with MS tend to be older with higher disease activity, which calls for more attention.

Objective To evaluate the validity of assessing synovitis and tenosynovitis by using musculoskeletal ultrasound scoring systems after standardized training in Chinese doctors.Methods All participants received a 30 minutes' training for the ultrasound scoring systems of synovitis and tenosynovitis.Ten static images were applied to evaluate the changes before and after training,respectively.Each parameter was assessed by a four scale semi-quantitative system recommended by outcomes measures in rheumatoid arthritis clinical trials (OMERACT).Paired t-test was used to assess the differences before and after training.Results Thirteen rheumatologists and two ultrasonographers completed the entire procedure.Significant differences were found before and after training when assessing the severity of gray-scale of synovitis (0.61± 0.30 vs 0.45±0.23;t=2.230,P＜0.05) and power Doppler of synovitis (0.57±0.26 vs 0.31±0.18;t=2.928,P＜0.05) and tenosynotis (0.56±0.15 vs 0.31±0.16;t=5.286,P＜0.05),while no significant difference was found when assessing the gray scale of tenosynovitis (t=-1.679,P＞0.05).Conclusion Standardized training is helpful to improve the validity of ultrasound scoring systems of synovitis and tenosynovitis in Chinese rheumatologists and ultrasonographers.The validity of assessing gray-scale of tenosynovits needs improvement.

Objective To investigate the outcomes of patients with rheumatoid arthritis (RA) treated by different combination of synthetic disease modifying antirheumatic drugs (DMARDs) under the guidance of treat-to-target strategy.Methods Forty-two RA patients with high disease activity were enrolled into this randomized,open-label and prospective study.It was comprised of a maximal 36-week induction phase and then followed by a maintenance phase up to 84 weeks.Combination of synthetic DMARDs was initiated in the induction phase,with or without low dose glucocorticoids (GCs) during the first 12 weeks.Patients who achieved low disease activity (LDA) were randomized into two maintenance groups.An increase of DAS28 by 0.6 was defined as relapse.The patients achieved LDA in the induction phase,relapsed during maintenance phase and possible relevant risk factors were analyzed.Results Twenty-seven (64％) patients achieved LDA during the induction phase.More non-smoking patients achieved LDA than those smoked [85％ (11/13) vs 55％(16/29),P＜0.05].During the maintenance phase,14 (61％) out of 27 patients relapsed.Patients taking GCs during the first 12 weeks had a significantly higher relapse rate compared to those without GC (83％ vs 36％,P=0.021).Patients who entered maintenance phase at week 12 had a significantly higher tendency to relapse compared to those who entered the maintenance phase at week 24 [75％(9/12) vs 33％(3/9),P=0.026].Conclusion Smoking seems to be a risk factor for RA patients who fail to reach LDA.Low dose GCs as a bridge therapy may require a longer duration.High relapse rates in both the maintenance groups indicat that a longer tight induction phase may be appropriate before downstairs therapy.

Objective:To verify the fracture risk assessment tool ( FRAX) to estimate the probability of osteoporotic fracture in patients with rheumatoid arthritis ( RA ) with or without bone mineral density (BMD), and identify associated risk factors of osteoporosis .Methods: In the study, 200 patients with rheumatoid arthritis aged more than 40 years in Peking University First Hospital from Dec .2009 to Dec. 2012 were recruited.Clinical information was obtained from a questionnaire of their case history and medical records.FRAX tool was administered.Their lumber spine and left femoral BMD were determined by dual energy X ray absorptiometry.The gender, age, disease duration, menopause status, body mass index ( BMI) and accumulative dose of glucocorticoid were obtained in retrospect .Correlation analysis was conducted between the BMD and clinical information .Results:The study population ( female, 77.5%) had a mean age of 59.4 years, in which 10 (13%) patients showed a normal BMD, 67 (87%) were osteopenia or osteoporosis , while 32 patients (16%) had fragile fracture.Compared with the patients with normal BMD, the subjects with low BMD had significantly older age , longer period for corticoids usage , higher day dose and accumulated dose of corticoids .The 10-year fracture risk of sustai-ning major osteoporotic fractures and hip fracture was higher .No significant difference was observed be-tween the 10-year fracture risks calculated with BMD and without BMD .The values of the different area under the receiver operating characteristic ( ROC) curve ( AUC) for major and hip fractures calculated in three ways:without BMD, with the femoral neck BMD, and with T-score.The best result was for FRAX tool for hip fracture with the T-score ( AUC 0 .899 ) .A stepwise multivariate linear regression model was constructed to explore the relationship between the different clinical factors studied and a low BMD . Three statistically significant variables for lumber BMD were pain on visual assessment scale ( VAS ) (P=0.02), fracture history (P=0.003) and a higher steroid accumulated dose (P=0.008).Three statistically significant variables for left hip BMD were age (P<0.001), fracture history (P=0.05) and lower BMI ( P=0.03) .Conclusion:Low BMD is a common complication in RA patients .Risk factors for major fracture and hip fracture are increased .There is a positive correlation between FRAX calculated with and without BMD or T score .FRAX with the femoral neck T score or BMD presents a discriminatory capacity better than FRAX without BMD , according to the AUC ROC .

Objective To evaluate the prevalence of subclinical atherosclerosis in rheumatoid arthritis (RA) and the related risk factors.Methods Fifty RA patients without overt atherosclerotic disease and 121 control subjects matched for age and sex were recruited.Duplex carotid sonography was used to measure intima-media thickness (IMT) and plaque formation assessment.Differences between RA and the control group were compared, and the risk factors were explored.RA patients then were divided into two subgroups according to IMT and the comparison between the two subgroups were completed.T test, Mann-Whitney U test, chi-square test, Pearson's correlation and Logistic regression analysis were used for statistical analysis.Results Although RA patients had lower level of serum lipids and body mass index than the control group, the mean IMT value was significantly higher in the RA group than that in the control group [(0.78±0.18) mm vs (0.62±0.14) mm, t=5.853, P=0.000], and plaque formation was more prevalent [56.0％(28/50) vs 36.4％ (44/121),x2=5.596, P=0.018].The difference was especially significant in the younger groups (＜50 years old group and 50-60 years old group).Logistic regression showed that the presence of RA [OR=7.34, 95％CI (2.53, 21.25)], male [OR=2.0, 95％CI (91.25, 3.17)] and old age [OR=1.1, 95％CI (1.04, 21.15)] were the independent risk factors for abnormal IMT (thickened or the presence of carotid plaques).The RA patients were divided into two subgroups according to IMT.Compared with patients with normal IMT, patients with abnormal IMT were older and more common in postmenopausal, and had longer RA duration and higher cholesterol level.In treatment, less patients with abnormal IMT had been taking methotrexate (MTX) for more than 3 months compared with patients with normal IMT.Among these parameters, old age [OR=1.13, 95％CI (1.03, 1.23)] was shown to be the independent risk factor for abnormal IMT in RA patients, and more than 3 months of MTX treatment [OR=0.12, 95％CI (0.02, 0.71)] was the protective factor.Conclusion Atherosclerosis occurs frequently and prematurely in patients with RA and the presence of RA is an independent risk factor for atherosclerosis.Early primary prevention for atherosclerosis should be recommended.MTX probably has a positive effect on preventing atherosclerosis for RA patients, which needs to be confirmed by further study.

Objective To investigate the features and discrepancies of the ultrasound findings of shoulders in patients with rheumatoid arthritis (RA) and polymyalgia rheumatica (PMR).Methods Patients with RA and PMR who complained of pain,swelling or limited mobility of shoulder were enrolled for bilateral ultrasound assessment.Inflammatory lesions including long head biceps (LHB) tenosynovitis,subacromial-subdeltoid (SASD) bursitis,tendinosis of supraspinatus (SS) tendon effusion/synovitis in glenohumeral (GH) and acromioclavicular (AC) joints,as well as structural damages including SS tear,bone erosions and osteophytes on humeral head and AC joints were evaluated.Comparison of frequency of ultrasound features between the two groups was analyzed byx2 test.Results A total of 458 shoulders from 192 RA and 37 PMR patients were assessed by ultrasound.In RA patients,the most prevalent inflammatory findings were LHB tenosynovitis (31.3％),followed by SASD bursitis (25％),SS tendinosis (11.5％),AC and GH effusion/synovitis (10.4％ and 5.7％,respectively).LHB tenosynovitis was the most frequent finding in PMR patients (37.8％),followed by SS tendinosis (27％),SASD bursitis (24.3％),AC and GH effusion/synovitis (2.7％ and 0,respectively).Partial or complete tear of SS tendon was found in 9.9％ RA and 8.1％ PMR patients,respectively.SS tendinosis was more frequently presented in PMR than RA patients (x2=6.255,P＜0.05),while GH effusion/synovitis was more common in RA group (x2=3.983,P＜0.05).Bone erosions and osteophytes were common in both groups.SASD bursitis and SS tendinosis appeared to be more unilateral (77.1％ and 77.3％,respectively),while GH effusion/synovitis tended to be bilateral (63.6％) in RA patients.Conclusion Intra-articular inflammatory involvement (GH effusion/synovitis) is more frequent in RA,while peri-articular inflammatory involvement (SS tendinosis) is more frequent in patients with PMR.SASD bursitis and SS tendinosis appears to be unilateral,while GH effusion/synovitis tends to be bilateral in RA patients.
