Objective To discuss the feasibility and accuracy of left atrial appendage (LAA)ejection fraction by real-time 3 dimensional imaging (3D-EF),and tissue velocity of the LAA wall by tissue Doppler imaging (TDI)via transesophageal echocardiography (TEE)in assessing LAA functions.Methods A total number of 76 patients with atrial fibrillation (AF)were included in the study consecutively and underwent TEE for LAA investigations.3D-EF,fractional area change by 2 dimensional imaging (2D-FAC),peak emptying velocity (PEV),LAA tissue velocity by TDI at the mid-portion of lateral wall (TDI-L),mid-portion of septal wall (TDI-S)and the apical tip (TDI-A)were calculated.Results Statistic analysis showed the following results:1 )2D-FAC,3D-EF,PEV,TDI-L,TDI-S and TDI-A were all significantly higher in patients with sinus rhythm than those with AF during the TEE examinations (all P <0.05),and significantly higher in patients without spontaneous echo contrast (SEC)than those who had SEC (all P <0.05);2)The results of 3D-EF showed a good correlation with 2D-FAC (r=0.727,P =0.000),and their correlations with PEV were similar (2D-FAC and PEV:r =0.685;3D-EF and PEV:r =0.632,both P =0.000);3)TDI-A [(14.95±4.63)cm/s]were significantly higher than TDI-L [(12.62±3.96)cm/s]and TDI-S [(12.68±3.59)cm/s](both P =0.000).The correlations of TDI-A with PEV,2D-FAC and 3D-EF were all marked higher than those of TDI-L and TDI-S (with PEV:r=0.840 vs r=0.564,r=0.524;with 2D-FAC:r=0.701 vs r=0.486,r=0.504;with 3D-EF:r=0.753 vs r=0.493,r=0.522,all P <0.05). Conclusions 3D TEE is feasible and reliable in assessing LAA emptying function.The best location for LAA tissue velocity evaluation is the apical tip.

Objective To study the mutation of FLCN gene in Chinese patients with sporadic and familial primary spontaneous pneumothorax. Methods A complete genetic analysis of FLCN by use of SSCP-PCR was performed in 102 unrelated Chinese patients with isolated PSP. Results Three novel mutations (c. 924_926del, c. 1611_1631del and c. 1740C.T) and a previously reported mutation (c. 1733insC) were identified in five familial and five sporadic PSP patients. Of the 21 family members of patients with PSP including 3 previous considered as sporadic, 4 ( 19% ) had history of at least one episode of PSP and 9 (43% ) were FLCN mutant carriers without PSP. Seven of the nine (78% ) mutant carriers had pulmonary cysts detected by high-resolution computed tomography ( HRCT) . Although c. 924_926del and c. 1611 _1631 del were found in eight patients from the same geographic district, haplotype analysis demonstrated that they did not share the same affected haplotype,thus excluding common ancestry. Conclusion This study first demonstrates that FLCN mutation contributes to not only familial but also apparently sporadic' patients with isolated PSP. It suggests that mutation analysis and HRCT scan may be recommended for first-degree family members of PSP patients with FLCN mutations, irrespective of their family history status of PSP.

Objective To analyze the clinical and laboratory characteristics of systemic lupus erythematosus (SLE) in children. Methods Fifty-three inpatients, 5 boys and 48 girls with SLE, who aged from 7 to 14 years with a median age at 12 years, were enrolled into this study. A retrospective study was carried out to assess the clinical and laboratory features of these pediatric patients. Results The ratio of male to female patients was 1:9.6. Skin eruption was the most common initial manifestation (41.51%), followed by fever (20.75%) and arthralgia (20.75%). Systemic involvement was common, and 84.90% of these patients had hematological abnormalities, 60.38% renal involvement, 18.87% nervous involvement. The most common manifestation of hematological, renal and nervous involvement was anemia, proteinuria and seizures, respectively. Among the immunologic parameters tested, anti-nuclear antibody showed the highest positivity rate of 90.57%, followed by anti-dsDNA with a positivity rate of 67.92%. There was no significant difference between the male and female patients in the age of onset, SLEDAI score at admission and discharge, duration of hospitalization or the dose of corticosteroid used initially and at the discharge. Conclusion The manifestations of pediatric SLE are various, and multisystem involvement is common in these patients. Early diagnosis and active treatment might benefit the prognosis of pediatric SLE.

Objective To investigate the clinicopathological and prognostic characteristics of intestinal inflammatory myofibroblastic tumours(IMT)in middle-aged and elderly patients.Methods The clinical,pathologi-cal morphology,immunophenotype and follow-up results of 5 cases of intestinal IMT in middle-aged and elderly patients were retrospectively analyzed.Results 4 cases of IMT occurred in the right half colon and 1 in the ileum.Most patients(3/5)had a history of intestinal injury,starting the digestive tract symptoms and increased leukocytes.The tumor tissue was composed of fusiform myofibroblasts and fibroblasts arranged in storiform pattern,with an infiltrative growth pattern,accompanied by a large number of lymphocytes and plasma cells infiltration,collagen formation and myxedema.One case was atypically large and deformed.Immunophenotype:vimentin(5cases),SMA(5 cases),desmin(3 cases),ALK(3 cases),CK(2 cases)were positive.Caldesmon,CD34,β-catenin,MC,CD117,DOG1,S-100,BCL-2,CD99,CD68 were negative,and Ki-67 proliferation index was 1.28%to 10.01%.All the 5 cases underwent complete tumor resection and were followed up for 48.5 to 133 months.Among them,1 patient aged 83 was considered to have tumor recurrence 27 months after surgery.The other patient survived 122 months without tumor and died of other causes.All the others survived without tumor and were in good condition.Conclusion(1)Intestinal IMT in the middle-aged and elderly people in this group was more common in the right half colon,and most of them had a history of intestinal injury,first gastrointestinal symptoms and elevated white blood cells;(2)Vimentin and SMA were positive at the same time,and ALK was more positive;(3)4/5 patients had good surgical resection,and 1/5 patients could relapse 2～3 years after surgery;old age,ALK-positive,Ki67 up to 10%,atypia may be an important risk factor for intestinal IMT recurrence in the elderly,of which ALK-positive patients may have a recurrence risk of 1/3.
