ObjectiveTo evaluate the quality of life of residents in stricken area five years after Wenchuan earthquake, so as to explore the main influential factors such as gender, age, ethnic group, marriage status and the extent affected by the earthquake. MethodsUsing WHOQOL-BREF, 500 residents from Hanyuan county in Sichuan province were assessed in order to analyze their life quality and related factors. ResultsThe score on the overall WHOQOL-BREF and the level of each factor were significantly lower than the score on the normal people (P < 0.001). Male score in the factor of social relations significantly higher than female (t=3.963, P < 0.001). The overall score and the score of social factor were significantly lower in the minor than in the adults (t=-2.667, P < 0.01; t=-19.287, P < 0.001). And the quality score of social relationship was significantly lower in the single than in the married and cohabiting couples (P < 0.001; P < 0.01). ConclusionThe quality of life of residents in stricken area five years after Wenchuan earthquake was significantly lower than the national norm. There are significant differences in terms of gender, age, marriage status and earthquake damage on social relations. Steady intimate relationships with others help improve the quality of life of residents in stricken area. Besides, compared those with average damage or no damage, the residents with serious damage are relatively worse in the overall quality of life as well as environmental conditions.
ObjectiveTo explore the dyeing conditions of reticular fiber staining of liver puncture tissue stained by BenchMark automatic special staining instrument, evaluate the staining effect, and share the using experience.MethodsA total of 30 cases of liver puncture specimens from April to May 2019 in West China Hospital of Sichuan University were selected. They were fixed with 4% neutral formaldehyde fix solution, treated with automatic dehydrator, embedded in paraffin, stained with adhesive slides, and baked in 65℃ oven for 30 min. Each specimen was sliced in duplicate, with a thickness of 5 μm. One was reticular fiber stained with BenchMark automatic special staining instrument under the dyeing condition according to the using experience of the laboratory, and the other was reticular fiber stained by manual Foot staining method according to the standard operating procedure of the laboratory. The staining effect under microscope was observed by a chief pathologist with extensive slide-reading experience.ResultsThe success rate of instrumental method was 100.0% (30/30), and that of the manual method was 76.7% (23/30). The difference in success rate between the two methods was statistically significant (χ2=5.143, P=0.023).ConclusionThe reticular fiber staining effect of BenchMark automatic special staining instrument is stable and reliable, and the success rate is higher than that of manual Foot staining.
Quality control refers to the general term of operation technology which activities to meet the quality requirements. Quality control is not only the need of the development of the laboratory itself, but also the important requirement of the laboratory accreditation organization for the development of the laboratory. To carry out quality control, first of all, a complete quality control system should be established. According to the pathological experiment process, which can be divided into pre-analysis, in-analysis and post-analysis quality control. There are some similarities between special staining and hematoxylin-eosin staining, but the details are slightly different. There are many kinds of special dyeing items, and each dyeing step is complicated, so it is difficult to control the quality according to the quality control technology of conventional pathological staining. This article reviews the whole process quality control of special dyeing by summarizing the literature and work experience, so as to contribute to the subsequent improvement of the quality of special dyeing.
