Objective To evaluate the reliability and validity of IBS-QOL scale in irritable bowel syndrome (IBS) patients. Methods IBS-QOL scale was applied to survey the quality of life of 123 IBS patients. The split-half and internal consistency method were used to evaluate the reliability, and with the construct method to evaluate the validity. Results The split-half reliability was 0.86. Cronbach’s α-coefficient of all domains was between 0.71 and 0.89 except body image and food avoidance; In the correlation analysis, the correlations between items and its subscale structure were above 0.60 (except interference with activity), but there were no correlations between items and other subscale structure. Eight components from factorial analysis were in accordance with theoretical structure.The cumulative contribution rate was 72.7%. Conclusions The reliability and validity of IBS-QOL scale are acceptable. It might be useful for us to assess the QOL of IBS patients in China.
Objective To compare the clinical effect of three operations for one-stage radical correction of small left ventricle in children with tetralogy of Fallot (TOF). Methods We retrospectively analyzed the clinical data of 120 patients with left ventricular dysplasia and TOF undergoing one-stage radical surgery in the First Hospital of Hebei Medical University from December 2004 to May 2017. According to the different types of operation used, they were divided into 3 groups, including a routine group (30 patients, 16 males and 14 females, aged 11.58±2.05 months ranging from 3-24 months), a large patch group (40 patients, 22 males, 18 females, aged 11.22±2.24 months ranging from 3-25 months) who were treated with a large patch, and an enlarged ventricular septal defect group (50 patients, 26 males, 24 females, aged 10.17±2.15 months ranging from 3-22 months) using new left ventricular enlargement technique to enlarge ventricular septal defect. The clinical effect of the three operations were compared. Results The incidence of postoperative low cardiac output syndrome (6.0% vs. 40.0%vs. 50.0%, P<0.05), renal failure (4.0%vs. 37.5% vs.46.7%, P<0.05), infection rate (10.0%vs. 50.0% vs.66.7%, P<0.05), mortality (2.0%vs. 12.5% vs. 20.0%, P<0.05), ventilator-assisted time (8.34±5.24 hvs. 36.14±10.91 h vs. 38.58±10.12 h, P<0.05), ICU stay (4.13±1.01 dvs. 7.64±2.11 d vs.8.03±3.03 d, P<0.05), hospital stay (10.48±4.26 dvs. 21.02±3.23 d vs. 22.52±2.93 d, P<0.05) and hospitalization costs (51 300±9 400 yuanvs.103 200±39 300 yuan vs. 115 500±35 200 yuan, P<0.05) were less in the enlarged ventricular septal defect group compared with the other two groups. Conclusion The clinical effect of enlarged ventricular septal defect is better than that of the routine and large patch methods, and long-term efficacy should be further followed up.
