Psoriatic arthritis is a chronic systemic autoimmune disease, characterized by psoriasis skin lesions and inflammation of the spine and joint. It has complicated clinical manifestations and individual variations. Nearly half of the patients will have joints erosion in two years, which is crippling. The severity of the skin and joint disease frequently do not correlate with each other. Currently, the understanding of the disease is insufficient in China with the lack of standardized diagnosis and treatment. Therefore, researchers from the Chinese Rheumatology Association formulated this specification based on the diagnosis and management experience together with guidelines at home and abroad. The specification summarizes the present situation of domestic diagnosis and treatment, aiming to standardize the diagnosis process and treatment protocols of psoriatic arthritis. Furthermore, it can reduce misdiagnosis and missed diagnosis, as well as improve the prognosis.

ObjectiveTo examine the clinical features of fractures and related risk factors in patients with rheumatoid arthritis(RA) in China.MethodsSix hundred and eighty-one RA patients were randomly selected from department of rheumatology of 18 hospitals of China.Data were obtained from the questionnaire,including age,sex,disease duration,the involvement of joints,treatment regimen,features of fractures etc.The possible risk factors of fracture in patients with RA were analyzed with a multi-variate Logistic regression analysis.Results① In 681 RA patients of the survey,48 patients had 54 fractures,and the incidence of fractures was about 8％.② Fractures occurred at various sites.Foot/ankle,femur,spine and wrist were the mostfrequent sites.③ The Logistic regression analysis showed that several factors increased the risk of fracture in RA patients,including long disease duration (OR:1.245,95％CI:0.987-1.570,P=0.065),male gender(OR:0.433,95％CI:0.199-0.942,P=0.035),more deformed joints(OR:1.042,95％CI:1.006-1.079,P=0.023),family history of RA (OR:2.201,95％CI:0.984-4.923,P=0.055),and high scores of SF-36(OR:1.017,95％CI:1.002-1.033,P=0.028).④ According to the degree of correlation from strong to weak,the risk factors of fracture were disease duration,SF-36,sex,number of deformed joints and family history of rheumatoid arthritis.ConclusionThe incidence of fracture is high in patients with rheumatoid arthritis.Several factors could increase the risk of fractures in RA patients,including long disease duration,male gender,more deformed joints,and family history of RA.In order to prevent the occurrence of fractures,cautions should be taken to prevent the development of fractures and treat the disease aggressively to suppress the disease activity of RA.

Objective To describe the distribution of medication costs of rheumatoid arthritis patients, and to analyze the factors that may affect the costs. Methods Data were obtained from a 12-month retrospective investigation of patients with rheumatoid arthritis (RA) across China. Department of Rheuma-tology of 18 hospitals were randomly selected. The data about their social conditions, clinical conditions, medications associated with RA such as disease-modifying antirheumatic drugs (DMARDs), non -steroidal anti -inflammtory drugs (NSAIDs), steroids, biologic agents were collected, and the costs of drugs were calculated. A non-parameter test and multivariate logistic regression analysis were performed. Results Six hundred and forty six patients were enrolled into the study, 435 completed data were chosen for analysis. The results demonstrated that the average costs per patient for medications in the past year was 8018 . The total medication costs were further subdivided into the following parts: DMARDs, (represented 20% of the total costs), biologic drugs (49%), NSAIDs (4%), herbal drugs (22%), steroids (1%). Data analysis showed that patients with higher education and higher incomes, with medical insurance,better health function status and outpatients paid more on DMARDs. Extra-articular manifestations increased the odds of the high-cost group (OR: 2.180, 95%CI: 1.335～3.558, P=0.002), while poor health function status increased the probability of paying high costs (OR: 1.373, 95%CI: 1.012～1.863, P=0.041). Conclusion High medication costs in RA do exist in RA patients. The costs of medication is associated with health function status and the presence of extra-articular manifestations.

Objective To compare right anterolateral minithoracotomy and traditional median sternotomy in the treatment of left atrial myxoma. Methods Forty-one patients with left atrial myxoma treated in our hospital from January 2009 to January 2018 were divided into two groups according to the operation method: a right anterolateral minithoracotomy group including 15 patients, with 7 males and 8 females, aged 45.1±15.4 years; a median sternotomy group including 26 patients, with 10 males and 16 females, aged 49.4±11.9 years. The clinical data of the two groups were compared. Results There was no significant difference in preoperative clinical data between the two groups. All patients completed the operation without perioperative death. There was no significant difference in the operation time, cardiopulmonary bypass time, aortic clamp time or the incidence of postoperative complications between the two groups. However, compared with the median sternotomy group, the right anterolateral minithoracotomy group had shorter duration of mechanical ventilation, ICU stay and postoperative hospital stay, and less volume of drainage and blood transfusion 24 hours after surgery (all P<0.05). After 3–106 months follow-up, no recurrence was observed in both groups. Conclusion Compared with traditional median sternotomy for left atrial myxoma resection, right anterolateral minithoracotomy is safe, effective and less traumatic. It can be used as a routine treatment for left atrial myxoma.

Objective    To analyze the near-term clinical efficacy of two different surgical procedures (Sun's procedure and Debranching combined endovascular stent-graft procedure) to cure Stanford type A aortic dissection, and summarize the clinical experience to help better master the indications of the two surgical procedures. Methods     We retrospectively analyzed the clinical data of 46 patients with Stanford A aortic dissection in our hospital between September 2014 and September 2017. There were 39 males and 7 females at age of 20–74 (48.67±11.80) years. According to different surgical methods, the patients were divided into a Sun's procedure group (26 patients) and a debranching combined endovascular stent-graft procedure group (20 patients). The clinical effect of the two groups was compared. Results     The debranching combined endovascular stent-graft procedure group was significantly superior to the Sun's group in cardiopulmonary bypass (CPB) time, aortic cross clamp(ACC) time, intraoperative urine output, postoperative mechanical ventilation time, postoperative 24 h volumes of drain, CICU time, renal function recovery of postoperative 72 h and total hospital stay(P<0.05). The incidence of transient neurological damage after operation in the debranching combined endovascular stent-graft procedure group was significantly lower than that of the Sun's procedure group(P<0.05). The follow-up time ranged from 3 to 36 months. And the follow-up rate was 90.5%. One patient in the Sun's procedure group died of serious pulmonary infection postoperative 30 days. One patient in the debranching combined endovascular stent-graft group was found to have internal leakage in the early postoperative examination and   disappeared after 6 months. Sun's procedure group did not find endoleak. All patients during the follow-up time did not appear brain, coagulation disorders, stroke, paraplegia, upper limb ischemia and other complications. Conclusion     For Stanford type A aortic dissection, debranching combined surgery may have the risk of postoperative endoleak, but the overall effect is superior to Sun's operation. Therefore, debranching combined surgery should be preferred for the treatment of this type of dissection.

Objective    To analyze the effect of loop-in-loop technique and annuloplasty ring for the treatment of mitral valve prolapse (MVP) under total thoracoscopy. Methods    Between May 2012 and May 2017, 21 patients with MVP underwent mitral valve repair in our hospital. There were 12 males and 9 females with a mean age of 50.90±9.66 years and the mean weight of 64.81±11.56 kg. Loop-in-loop artificial chordae tendonae reconstruction and mitral annuloplasty were performed through the right atrial-atrial septal incision under total thoracoscopy. The water test and transesophageal echocardiography were performed during the operation to evaluate the effect of mitral annuloplasty. Data of echocardiography and chest radiography were collected postoperatively one week, before discharge and after discharge. Results    All the operations were successful without re-valvupoplasty or valve replacement, conversion to median thoracotomy, malignant arrhythmia, perioperative death or wound infection. Among them, 10 patients underwent tricuspid valvuloplasty, 1 patient underwent tricuspid valvuloplasty plus radiofrequency ablation simultaneously. The mean cardiopulmonary bypass time was 255.57±37.24 minutes, aortic occlusion time was 162.24±19.61 minutes, the number of loop was 2–5 (3.29±0.78), the size of ring was 28–34 (31.11±1.88) mm, ventilator assistance time was 19.43±14.68 hours, ICU time was 58.45±24.60 hours and postoperative hospital stay was 12.28±3.61 days. Transthoracic echocardiography was re-examined postoperatively. Mild-mitral regurgitation was found in 3 patients. Warfarin anticoagulant therapy was given orally for 6 months postoperatively. The patients were followed up regularly for 2–51 months at 1, 3, 6 and 12 months postoperatively. Left ventricular end-diastolic diameter (LVEDD) was 45.06±2.96 mm, left ventricular end-diastolic volume 108.11±17.09 mL, left atrial diameter (LAD) 35.56±6.93 mm and cardiothoracic ratio 0.53±0.13 at discharge which were significantly smaller than those at admission (P<0.05). Pulmonary artery pressure was 19.22±6.38 mm Hg which was significantly lower than that at admission (P<0.05), but left ventricular ejection fraction (62.33%±4.00%) had no significant change (P>0.05). The LAD and LVEDD were significantly smaller than those before operation, and the cardiac function improved to some extent during the follow-up. No new mitral valve prolapse, increased regurgitation, infective endocarditis, thromboembolism or anticoagulation-related complications were found during the follow-up. Conclusion    Loop-in-loop artificial chordae tendon implantation combined with mitral annuloplasty is a safe and effective method for MVP under total thoracoscopy with minimal trauma, satisfactory cosmetic effect, and good early- and medium-term results. It is worth of popularizing. However, the operation time needs to be further shortened, and its long-term clinical effect needs further follow-up and other researches to confirm.
