Objective To develop the Chinese version of Attribution Questionnaire-27 and examine its replicability,reliability and validity.Methods The questionnaire was translated using the standard translation/back-translation method and examine its replicability,reliability and validity in 230 medical students who were selected by convenient method.Results The Cronbach α coefficient for Attribution Questionnaire-27 was 0.82 and ranging between 0.55 and 0.84 for the subscales.The test-retest reliabilities of the total scale was 0.77 and the subscales was between 0.61 to 0.81 after one week.Confirmatory factor analysis confirmed the hypothesized six factors attribution of responsibility model (x2/df=3,GFI=0.925,NFI=0.880,CFI=0.856,IFI=0.761,RMSEA=0.094) and three factors dangerous model (x2/df=1.773,GFI=0.959,NFI=0.941,CFI=0.973,IFI=0.973,RMSEA=0.058).The path analysis results support the existing theoretical assumptions.Condusions The Chinese version of Attribution Questionnaire-27 has good reliability and validity and can be used in medical student.

Objective To investigate the basic status and the 15 quality indicators in clinical laboratory of medical institutionin in Qinghai provinces, and to understand the quality status.Methods Clinet-EQA system was applied by Qinghai Center for Clinical Laboratories to provide the electronic questionnaire for the clinical laboratory of 106 medical institutions in April 2016 and report related results online.The software of Clinet-EQA system and SPSS13.0 were used for 15 quality indicators for statiatical analysis,13 indicators expressed in rate were further evaluated with sigma scales.Results Totally 102 laboratories returned questionnaires, the rate was of 96.2%.8/13 quality indicators of the overall sigma levels were all >3.The average level of 4 quality indicators such as the sample type error rate was slightly lower than the national.Comparison of the 4 quality indicators of each grade hospital in Qinghai and the same grade hospital in the national, secondary hospital in clinical chemistry, immunology, clinical examination,microbiology in the four major performed better than tertiary hospital.In routine examination, pre-analytical TAT average level of clinical chemistry and immunology was about 50 min,and of blood,urine and stool was 45 min.Pre-analytical TAT in emergency examination for all four disciplines were about 15 min.Intra-analytical TAT for clinical chemistry was the longest,which was 120 min for routine examination and 40 min for emergency examination,respectiely.The average level of the median TAT of blood,urine and stool in routine examination of Intra-analytical in Qinghai was longer than the national.For example of clinical chemistry, routine examination both in pre-analytical TAT and in Intra-analytical TAT was statistically significant in different scales of laboratories,and emergency examination in pre-analytical TAT and in Intra-analytical TAT was not statistically significant.Conclusions 4/13 quality indicators which expressed in rate in the average level in Qinghai province were lower than the national,the average level of the median TAT of blood,urine and stool in routine examination of Intra-analytical in Qinghai was longer than the national.The laboratory should focus on the weak links and continue improvement.

INTRODUCTION: Acute malignant large bowel obstruction (MBO) occurs in 8%-15% of colorectal cancer patients. Self-expandable metal stents (SEMS) have progressed from a palliative modality to use as bridge to surgery (BTS). We aimed to assess the safety and efficacy of SEMS for MBO in our institution. METHODS: The data of patients undergoing SEMS insertion for MBO were reviewed. Technical success was defined as successful SEMS deployment across tumour without complications. Clinical success was defined as colonic decompression without requiring further surgical intervention. Rates of complications, median time to surgery, types of surgery and rates of recurrence were studied. RESULTS: Seventy-nine patients underwent emergent SEMS placement from September 2013 to February 2020. Their mean age was 68.8 ± 13.8 years and 43 (54%) patients were male. Mean tumour length was 4.2 cm ± 2.2 cm; 89.9% of malignant strictures were located distal to the splenic flexure. Technical and clinical success was 94.9% and 98.7%, respectively. Perforation occurred in 5.1% of patients, with none having stent migration or bleeding. Fifty (63.3%) patients underwent SEMS insertion as BTS. Median time to surgery was 20 (range 6-57) days. Most (82%) patients underwent minimally invasive surgery. Primary anastomosis rate was 98%. Thirty-nine patients had follow-up beyond 1-year posttreatment (median 34 months). Local recurrence and distant metastasis were observed in 4 (10.3%) and 5 (12.8%) patients, respectively. CONCLUSION Insertion of SEMS for acute MBO has high success rates and a good safety profile. Most patients in this audit underwent minimally invasive surgery and primary anastomosis after successful BTS.
