局部晚期食管鳞癌新辅助放疗剂量与病理完全缓解关系分析

目的 探讨接受新辅助放化疗的局部晚期食管鳞癌患者新辅助放疗剂量与病理完全缓解(pCR)的关系。方法 收集2017-2019年间在四川大学华西医院肿瘤中心经病理确诊为食管鳞癌并接受新辅助放化疗和手术的 116例局部晚期患者临床资料。116例患者中 40~45Gy组 80例,≥45Gy组 36例,分析两组术后pCR率。结果 全组患者的pCR率为38.8%(45/116),40~45Gy组与≥45Gy组的pCR率分别为44%(35/80)和28%(10/36)(P=0.105)。结论 术前新辅助采用较高的放疗剂量不增加局部晚期食管鳞癌的pCR率,有必要进行前瞻性的临床研究确定合适的新辅助放疗剂量。

Advantages of Anti-Inflammatory Acupuncture in Treating Sepsis of Coronavirus Disease 2019

Background: Sepsisis one of the mostserious complications and a leading cause of death in patients with coronavirus disease 2019 (COVID-19). In general, it isthe result of an unregulated inflammatory cascade such as a postinfection “cytokine storm.” The conventional treatment mainly relies on glucocorticoids, of which curative effects are not ideal, as they come with significant side effects. It is critical to seek or develop other effective therapeutics in dealing cytokine storm to fight COVID-19 with sepsis. Aims and Objectives: Raise awareness of the significance applying anti-inflammatory acupuncture in dealing COVID-19 patients with sepsis and provide an appropriate acupuncture protocol that can be easily integrated into existing medical guideline. Materials and Methods: Current evidences from animal experiments and clinical trials about acupuncture in treating infectious sepsis are reviewed, and a detailed discussion on advantages of anti?inflammatory acupuncture is followed, then the rationality on the point selection and stimulation parameters of acupuncture is analyzed to propose an appropriate acupuncture protocol. Results: Current experiments have shown that acupuncture can play a significant role to improve inflammation reaction and reduce mortality in infectious animal and patients with sepsis and its mechanisms are mainly achieved by stimulating the vagus?cholinergic anti?inflammatory pathways.Applying acupuncture in treating COVID-19 patients with sepsis hasfour aspects of advantages. Moreover, a simple and convenient clinical acupuncture protocol including point selection and appropriate stimulation parameters is proposed. Conclusion: Acupuncture, especially electroacupuncture, has shown potentials in effectively treating infectious sepsis of animal models and critically ill patients in small sample studies by stimulating the nervous system, but has been largely overlooked in the clinic so far. It is advised that acupuncture should be integrated into the existing medical guidelines in dealing with COVID-19 complicated with sepsis.     

Steep Decrease of Gender Difference in DSM-IV Alcohol Use Disorder: A Comparison of Two Nation-wide Surveys Conducted 10 Years Apart in Korea

While decreasing trend in gender differences in alcohol use disorders was reported in Western countries, the change in Asian countries is unknown. This study aims to explore the shifts in gender difference in alcohol abuse (AA) and dependence (AD) in Korea. We compared the data from two nation-wide community surveys to evaluate gender differences in lifetime AA and AD by Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV). Face-to-face interviews using the Composite International Diagnostic Interview (CIDI) were applied to all subjects in 2001 (n=6,220) and 2011 (n=6,022). Male-to-female ratio of odds was decreased from 6.41 (95% CI, 4.81-8.54) to 4.37 (95% CI, 3.35-5.71) for AA and from 3.75 (95% CI, 2.96-4.75) to 2.40 (95% CI, 1.80-3.19) for AD. Among those aged 18-29, gender gap even became statistically insignificant for AA (OR, 1.59; 95% CI, 0.97-2.63) and AD (OR, 1.18; 95% CI, 0.80-2.41) in 2011. Men generally showed decreased odds for AD (0.55; 95% CI, 0.45-0.67) and women aged 30-39 showed increased odds for AA (2.13; 95% CI 1.18-3.84) in 2011 compared to 2001. Decreased AD in men and increased AA in women seem to contribute to the decrease of gender gap. Increased risk for AA in young women suggests needs for interventions.
