ObjectiveTo investigate the association between serum level of osteopotin(OPN) and disease activity of rheumatoid arthritis (RA) patients, and explore the importance of OPN in the pathogenesis of interstitial lung disease (ILD) in RA. MethodsSixty-five RA patients and 20 healthy controls were pros-pectively enrolled. RA patients were divided into active group(n=43) and inactive group(n=22), and ILD groups (n=24) and non-ILD group (n=41). Enzyme-linked immunosorbent assay (ELISA) was used to detect the serum levels of OPN in patients with RA and healthy controls, and the relationship between OPN and other clinical and laboratory findings were analyzed.Results① Serum OPN tended to be significantly higher in RA patients (median, 18.0 ng/ml) than in the healthy controls (median, 14.3 ng/ml), P<0.01; ②The serum level of OPN in RA patients showed a significant positive correlation with the course of disease, numbers of tender joints , ESR and CRP, but no positive relationship was found in number of swollen joints; ③ The serum level of OPN was significantly higher in RA-ILD patients(median, 20.0 ng/ml) than that in non-lLD (median, 17.0 ng/ml, P<0.05). And there was remarkable negative correlation between the concentration of serum OPN and the value of PaO2, but no association was found with pulmonary function %VC and %DLCO. ④ Compared with the non-ILD group, the ILD group had more active disease in terms of tender joint counts and swollen joint counts, ESR, CRP(P<0.01) and the serum titer of RF-IgM,(P<0.05). ConclusionOPN plays a role in the pathogenesis of RA and is related to the disease activity. It may serve as an active disease inflammatory marker of RA . OPN may be involved in the pathogenesis of RA related ILD and is associated with the severity of pulmonary damage.

Objective To observe the prognosis and correlated factors of cystoid macular edema (CME) secondary to uveitis.Methods A retrospective,noncomparative case series study.The clinical data of 31 uveitis patients with CME were collected from Uveitis & Ocular Immunology Service of Tianjin Medical University Eye Hospital from August 2011 to December 2015.Pre-treatment and post-treatment data were collected,including details of best-corrected visual acuity (BCVA),central macular thickness (CMT),other macular complications,and intraocular pressure (IOP).Results Twenty-seven patients (36 eyes) were analyzed.At the 1 st month after treatment,complete resolution of CME was achieved in 14 eyes (38.9％),BCVA increased from (0.66 ±0.36) LogMAR at baseline to (0.40 ±0.31) LogMAR (P ＜0.001),and CMT decreased from (469.0 ± 99.1) μm at baseline to (368.7 ± 85.9) μm (P ＜ 0.001).At the 3rd month after treatment,complete resolution of CME was found in 19 eyes (52.8％),no significant difference was found in CMT(323.9 ±60.0) μm or BCVA(0.37 ±0.32)LogMAR compared with the 1 st month after treatment (P ＞ 0.05),significant difference was found in CMT(P ＜0.001) or BCVA(P ＜0.001) before the start of treatment.At the 6th month or more after treatment,complete resolution of CME occurred in 25 eyes (69.4％),BCVA(0.32 ± 0.28)LogMAR was significant difference compared with that before the start of treatment(P ＜ 0.05),at the 1st month(P ＜ 0.05),at the 3rd month (P ＜ 0.05).CMT (294.2 ± 81.2) μm was significant difference compared with that before the start of treatment(P ＜0.001),at the 1st month(P ＜0.001),however,no significant difference was compared with that at the 3rd month (P ＞ 0.05).At the 6th month or more after treatment,11 eyes (30.6％) had a persistent macular edema,complicated with macular epiretinal membrane,no significant correlation between the reduction of CMT(185.0 ± 114.2) μm and the improvement of BCVA (0.29 ± 0.21) LogMAR was found (r =0.322,P=0.052),while the improvement of BCVA(0.29 ± 0.21)LogMAR was negatively associated with the duration of CME(8.4 ±9.8)months(r =-0.395,P =0.015).Conclusion Current therapies are effective in curing most of the CME secondary to uveitis.The duration of CME,is correlated with poor final visual acuity,the presence of ERM is an important factor associated with regression of CME.

Objective To investigate the effects of solution-focused brief therapy on self-perceived burden and quality of life in patients with stroke.methods 60 patients with stroke recruited at the department of rehabilitation of a hospital in Chengde city from January to June 2016 were divided into control group (n=30) and experimental group (n=30).Both groups received conventional nursing care and rehabilitation treatment.In addition,the experimental group received psychological intervention of solution-focused brief therapy,2-3 times a week,30-45 minutes for each time.The self-perceived burden scale(SPBS),memorial university of Newfoundland scale of happiness(MUNSH) and short from 36 health survey questionaire(SF-36) were used to assess the patients before and after intervention.Result s(1)The differences of the scores of SPBS ((39.27±5.83) vs (22.40±4.03),t=16.248,P<0.01) and MUNSH ((4.20±4.50) vs (31.10±3.66),t=-24.136,P<0.01) for the experimental group before and after the intervention were statistically significant.There were statistically significant differences in scores of SPBS ((22.40±4.03) vs (35.30±2.63),t=-14.683,P<0.01) and MUNSH ((31.10±3.66) vs (19.67±3.64),t=12.127,P<0.01) between the experimental group and control group after the intervention.(2)The scores of physiologic functioning,general health,vitality,social functioning,role-emotional and mental health for the experiment group were higher than before(t=-23.427--6.624,all P<0.01).After the intervention,the scores of physiologic functioning,general health,vitality,social functioning,role-emotional and mental health in the experiment group were higher than those in control group(t=5.705-12.806,all P<0.01).Conclusion Solution-focused brief therapy can effectively reduce the self-perceived burden of stroke patients and improve their quality of life.

Objective To summarize and describe clinical features and treatment outcome of syphilitic scleritis.Methods A retrospective study was conducted in patients diagnosed as syphilitic scleritis from 2011 to 2016 in our hospital.Clinical characteristics and prognosis were evaluated.Results Seven patients (7 eyes) were diagnosed as syphilitic scleritis by clinical and serological examinations.All patients were unaware that they had syphilis infection before visit.The ocular manifestation was the only clinical fmdings in three patients.Both treponema pallidum particle agglutination and rapid plasma regain were positive.Meanwhile,the scleritis infection was excluded,tests for human immunodeficiency virus (HIV) were negative.Syphilitic scleritis was unilateral in all patients,and the duration was from one week to two years.Initial symptoms were varied in degree of ocular redness,pain and visual impairment.Two patients presented with anterior episcleritis,nodular anterior scleritis was found in three patients,one patient showed diffuse anterior scleritis,and one patient presented with diffuse episcleritis combined with acute syphilitic posterior placoid chorioretinitis.All patients were treated with penicillin G,and inflammation resolved quickly after treatment.Conelusion Syphilitic scleritis is rare and ease to be misdiagnosed,various types of anterior scleritis is the main manifestation.Syphilitic serologic test should be performed for the suspected cases.The prognosis is well with anti-syphilis therapy.

This report presented a case of disseminated infection with nocardia in lupus erythematosus (SLE) and reviewed the current literature. Nocardiosis was a rare, sometimes life-threatening opportunistic infection in SLE patients. The isolation and identification of pathogen was fundamental for the diagnosis of nocardiosis. Sulfonamides were traditionally the agent of choice for treatment of nocardiosis; while it must be given for several months even more than one year, particularly in patients with suppressed immune function. Issues regarding the drug resistance and the toxicity of sulfonamides in long-term therapy needed to be considered. Linezolid could be an effective agent for the treatment of nocardiosis, whether it could reduce the treatment course need to be further studied.

Acquired syphilis uveitis,due to lack of the characteristic features,presents with various types.The most common type is posterior uveitis and panuveitis,including chorioretinitis,retinal vasculitis,optic nerve retinitis.The diagnosis and assessment of response to treatment depends mainly on the serological diagnostic tests,including nontreponemal and treponemal test.Acquired syphilis uveitis often presents with manifestations similar to various types of uveitis,especially to autoimmune uveitis and other infectious uveitis,so differential diagnosis is important.The gold standard treatment for active syphilitic uveitis is penicillin G,or doxycycline if patient is allergy to penicillin.Clinically misdiagnosis and delayed treatment may result in irreversible visual impairment and severe systemic and eye complications.However such timely treatment always has a good prognosis.
