Therefore, the aim of this study was to use qualitative research methods exploring the strengths, weaknesses, opportunities and threat factors that could facilitate or impede individuals' abstinence in a real-life context from the perspectives of MA abusers. Aim To use qualitative research methods exploring the strengths, weaknesses, opportunities and threat factors relating to individuals' abstinence in a real-life context. Method Semistructured interviews were conducted with 32 MA abusers recruited in Shanghai guided by open-ended questions on narrating the real-life catalysts and inhibitors related to craving, initiation, relapse and abstinence. All data were transcribed verbatim and analysed using a strengths, weaknesses, opportunities and threats (SWOT) analysis. Results The results of the SWOT analysis revealed that contextual factors including peer influence, prevalence and availability of MA, familiar venue of MA use, discrimination, sexual behaviours, alcohol, emotional states and their attitudes towards smoking MA were important factors that contribute to reinitiation and relapse. Surveillance systems, antidrug social workers, vocational skills trainings, moving to another city and family responsibility might serve as counter measures targeti叩 those mentioned weaknesses and threats above. Conclusion This SWOT analysis highlights the complex nature of relapse. Comprehensive interventions strengtheni叩 coping skills such as virtual reality techniques are desperately needed to facilitate individuals1 sustained abstinence.展开更多

Methods The expression of Survivin mRNA was detected by FISH method and TMA technology. Fifty-four cases of lung cancer and 10 cases of normal lung tissue were examined. Survivin mRNA was expressed in 66.7% （36/54） of lung cancer; the positive ratio of lung cancer was significantly higher than that of normal lung tissue （0/10;X^2= 15.238, P 〈 0.05）. The positive ratio of Survivin mRNA was significantly higher in poor differentiated cancer （20/24, 83.3% ） than moderate and well differentiated cancer （16/30, 53.3%; X^2 = 5.40, P 〈 0.05）. The positive ratio of Survivin mRNA was significantly higher in group with lymph node metastasis （27/32, 84.4%） than without lymph node metastasis （9/22, 40.9%; X^2= 11.084, P 〈 0.05）. The positive ratio of Survivin mRNA was significantly higher in stage Ⅲ-Ⅳ（12/13, 92.3%） than stage Ⅰ- Ⅱ （24/41,58.5%; X^2=5.066, P〈 0.05）. Conclusion Survivin mRNA highly expresses in lung cancer, which is related to the progress and malignant behavior. Survivin may play a promoting role in lung cancer genesis and progress and provide a basis for estimating prognosis and treatment.展开更多

This study aims to address this issue by conducting a propensity score matching(PSM) study.METHODS: A total of 727 non-high-risk acute PE patients were retrospectively evaluated. We evaluated the Bova score and risk stratification to examine the risk of deterioration. Deterioration defined as any adverse event within 30 days after admission. Computed tomographic pulmonary angiography was used to identify the embolism type. All patients were matched into four subgroups by PSM according to age, sex, Bova score, and risk stratification:(1) MPA and non-MPA embolism;(2) non-saddle MPA and non-MPA embolism;(3) saddle MPA and non-saddle MPA embolism;(4) saddle MPA and non-MPA embolism. Correlations were analyzed using Cox regression analysis, and deterioration risk was compared between subgroups using Kaplan-Meier analysis.RESULTS: Cox regression analysis revealed that MPA embolism was correlated with deterioration, regardless of whether saddle MPA embolism was included or excluded. Saddle MPA embolism was not correlated with deterioration, regardless of comparison with non-saddle MPA embolism or non-MPA embolism. Patients with MPA and non-saddle MPA embolism presented a high risk for deterioration(logrank test=5.23 and 4.70, P=0.022 and 0.030, respetively), while patients with saddle MPA embolism were not at a high risk of deterioration(log-rank test=1.20 and 3.17, P=0.729 and 0.077, respetively).CONCLUSIONS: Saddle MPA embolism is not indicative of a high risk of deterioration in nonhigh-risk acute PE patients.展开更多
