The West China hospital of Sichuan university has underwent four times emergency medical rescue (EMR) of earthquakes, measuring 5.7 Ms to 8.0 Ms on the Richter scale, happened at Wenchuan, Yushu, Yiliang and Lushan in recent 5 years, which gradually improved and supplemented Wenchuan experience. After Lushan earthquake, a total of 392 patients were received during 2 weeks. Among 321 hospitalized patients, there were 39 (12.15%) patients with critical injury and 14 (4.36%) patients who needed intensive care. 184 operations were performed. Based on the experiences of resource centralization, multidisciplinary cooperation, and hierarchical management, zero death, a new medical record, has been achieved among 43 patients with critical injury after centralized admission and treatment. A total of 12 medical rescue teams involving 88 healthcare workers were sent to the epicenter to join and guide EMR. Besides, rehabilitation and psychological experts came to Lushan on the first day of earthquake, and started clinical intervention of mental and physical health for people needed on the second day.
Lateral flow assay is widely used in the point-of-care testing on-site and in-home testing with the advantage of being simple, rapid, sensitive and cost-effective. Proper labels are the key factors in lateral flow assay. Traditional labels include colloidal gold, selenium nanoparticle, and carbon nanoparticle, among which the colloidal gold is most commonly used. Lateral flow assay has been improved as a result of the discovery of new labels, such as quantum dots and nanozyme recently. Meanwhile, transformation of qualitative detection to quantitative detection is gradually realized. This article aims at introducing the most often used and the latest lateral flow assay labels, providing a basis theoretical investigation on screening proper labels for lateral flow assay researchers.
bjective To investigate the correlation between expression of vascular endothelial growth factor(VEGF) of serum and tumor tissues and the clinical prognosis in patients with breast cancer. Methods The expressions of VEGF level of serum and tumor tissues in 44 patients with invasive duct breast cancer, 13 with benign breast diseases and 40 healthy controls. Serum VEGF level was measured by ELISA method. The protein expression of tissue VEGF, ER and C-erbB-2 were evaluated by immunohistochemistry LSAB method. Results Serum VEGF level and tissue VEGF expression in breast cancer were higher than those in benign breast diseases （P＜0.001）, and there was no significance in benign breast diseases and healthy controls （Pgt;0.05）. VEGF expression was correlated with lymph node metastasis (P＜0.01), ER and C-erbB-2 expression (P＜0.05, P＜0.01) and clinical stage （P＜0.01）. There were no statistical correlation between VEGF expression and age, tumor size (Pgt;0.05). Conclusion There is positively correlation between serum VEGF level and tissue VEGF expression, and between VEGF expression and clinic prognosis. Serum VEGF level may be one of important index of prognosis estimation in patients with breast cancer.
AMP-activated protein kinase (AMPK) is involved in the development and progression of tumors including hepatocellular carcinoma (HCC). However, studies on AMPK and tumorigenesis were largely based on experiments in vitro or tumor xenografts model. Here, we introduce a liver-specific AMPKα1 knockout mice model, which is achieved by Alb-Cre recombinase system. The expression of AMPKα1 in the liver of AMPKα1-/--Alb-Cre mice is absent. AMPKα1 knockout in the liver does not affect the growth and histological structure of mouse liver. This model provides a favorable tool to the study of the roles of AMPKα1 in liver metabolism or tumorigenesis.
