Objective To investigate and analyze the health care seeking behavior,financial burden and relative factors of patients with rheumatic diseases in Fujian Province.Methods Patients diagnosed with rheumatic diseases were investigated in Fujian Provincial Hospital from December 2013 to February 2014,including demographic data,health care seeking behavior and financial burden.Relevant factors were analyzed by Logistic regression.Results ① In this study,474 patients were enrolled.The ratio of male to female was 1∶2.38.② At the onset of symptoms,51.9％(246 cases) of patients visited a doctor as soon as possible,and 36.1％(171 cases) of them went to hospital within a month after disease onset.③ 74.1％(351 cases) of patients could adhere to medication regimen prescribed by doctors,and the most common reason for stopping medication was symptoms relieved (33.3％,41 cases).④ 63.1％(299 cases) of patients learned about the knowledge of rheumatic diseases from hospitals and doctors.⑤ 34.2％(162 cases) of patients spent 1 000-5 000 yuan every month on treatment.⑥ Insurance type could affect the time of first visit to hospital (P=0.004),while income and cost of therapy might impact patients' compliance (P=0.013,P=0.004).Conclusion Most patients will go to hospital as soon as possible and adhere to treatment.Economic situation is the main factor influencing health care seeking behavior of patients with rheumatic diseases.

Objective To evaluate the application of dynamic magnetic resonance imaging in the diagnosis of female stress urinary incontinence(SUI). Methods Dynamic magnetic resonance imaging(DMRI)were performed on 30 healthy female volunteers and 35 female SUI patients.DMRI of the pelvic floor at rest and OR maximal strain were performed by using sagittal T2-weighted fast gradient sequences.The distance of Urethra-vesical junction to the pubococcygeal line,the posterior vesicourethral angle and angle of inclination of the urethral axis were measured at rest and on maximal strain position.The t-value exact test were used to analyze the data. Results At rest the Urethravesical junction laid above pubococcygeal line on both control and SUI groups.Mean distance from the Urethra-vesical junction to pubococcygeal line at rest had no difference between the two groups.On straining,the mean Urethra-vesical junction descent distance in the SUI group(-0.9±1.1cm)was significantly higher than in control group(-0.14±0.3 cm),(P＜0.001).On straining,the mean angle of urethral inclination in the SUI group(65±37°)was significantly bigger than in control groups (17±21°),(P＜0.05).The posterior vesicourethral angle in the SUI groups(156±36°)was significantly bigger than in control groups(113±28°),(P＜0.05). Conclusion Dynamic magnetic resonance imaging is a non-invasive.easily applied method in the diagnosis of SUI.

Objective To investigate the protective effect of mild hypothermia on cerebral ischemia-reperfusion injury in rats and the effect of mild hypothermia on the expression of inhibitor of differentiation 2 (Id2) protein.Methods A total of 72 adult male rats were randomly divided into a sham operation group,a normothermia group,and a mild hypothermia group.A model of middle cerebral artery occlusion was induced by a suture method.The mild hypothermia group was treated with low temperature (anal temperature 33±1 ℃,tympanic membrane temperature 31±1 ℃).Modified Neurological Severity Score (mNSS) was used to evaluate neurological deficits,triphenyltetrazolium chloride staining was used to detect infarct volume,and Western blot was used to detect the Id2 expression in the ischemic cortex at ischemia-reperfusion 6,12,24,and 72 h,respectively.ResultsThe mNSS scores in the mild hypothermia group were significantly lower than those in the normothermia group,the infarct volumes were significantly smaller than those in the normothermia group at ischemia-reperfusion 6,12,24,and 72 h (all P<0.001).Western blot analysis showed that the Id2 expressions in the ischemic cortex in the mild hypothermia group were significantly lower than those in the normothermia group at ischemia-reperfusion 6,12,24,and 72 h (all P<0.05).Conclusion s Mild hypothermia can decrease neurological deficits and reduce infarct volume after cerebral ischemia-reperfusion,its mechanism may be associated with the down-regulation of the Id2 expression.

Objective To investigate the effect of auditory brainstem response(ABR)in clinical detection and severity assessment of autism spectrum disorder(ASD)in children with normal hearing.Methods ① A total of 55 autistic children(110 ears)with normal hearing and 55 children(110 ears)with typical development(TD)who did not differ in sex composition ratio and average monthly age were divided into four sub-groups according to age:≤24 months group(22 ears),25～36 months group(40 ears),37～48 months group(28 ears)and＞48 months group(20 ears).The ABR latencies and interpeak latencies were compared between ASD children and age-matched TD children.② ASD children were graded by severity according to the Diagnostic and Statistical Manual of Mental Dis-orders(DSM-V),and the correlations between the ABR latencies and interpeak latencies in autistic children with normal hearing and the severity grading were studied.Results ① No statistically significant differences in ABR wave latencies and interpeak latencies were found in autistic children with normal hearing under 24 months of age compared to age-matched TD children(P＞0.05).② Compared with children with TD,autistic children with nor-mal hearing at 25～36 months of age had significantly longer wave Ⅲ latencies and the interpeak latencies of Ⅰ-Ⅲ andⅠ-Ⅴ;the significantly longer wave Ⅲ,Ⅴ latencies,the interpeak latencies of Ⅰ-Ⅲ,Ⅲ-Ⅴ and Ⅰ-Ⅴ in autistic chil-dren with normal hearing at 37～48 months of age.Autistic children with normal hearing in the＞48 months group had significantly longer wave Ⅴ latencies and interpeak latencies of Ⅲ-Ⅴ,Ⅰ-Ⅴ than age-matched TD children(P＜0.05).③ The higher the ASD severity grading the longer the wave Ⅲ and V latencies and the longer interpeak latencies of Ⅰ-Ⅲ,Ⅲ-Ⅴ,and Ⅰ-Ⅴ(P＜0.05).Conclusion Differences in the level of auditory brainstem pathway de-velopment emerged at 25 months of age,and autistic children with normal hearing had significantly lower levels of auditory brainstem development than age-matched TD children.There were correlations between the latencies and interpeak latencies of ABR in autistic children with normal hearing and the severity grading.
