5.Effect of hyperthermia on the biological functions of human lung cancer cell line H1299 and its molecular mechanism
Cancer Research and Clinic 2017;29(2):79-82
Objective To explore the influences on biological function induced by hyperthermia in human lung cancer cell line H1299, and to investigate the possible molecular mechanism. Methods H1299 cells were cultured in vitro and divided into 2 groups. The cells in culture flasks of hyperthermia group were immersed into a water bath at 43 ℃for 1 h, and the cells of control group were cultured at 37 ℃. The cell growth was detected by CCK8 assay, and the cell cycle and apoptosis rates were detected by flow cytometry [propidium iodide (PI) staining and PI/Annexin V staining]. The effects of hyperthermia on migration and invasion abilities of H1299 cells were determined by Transwell migration and invasion assays, respectively. The expression of LLGL1 was measured by Western blot. Results The cell cycle had no significant difference between the two groups, but the apoptosis rate was significantly higher in hyperthermia group [(24.81 ±2.80) %] than that in control group [(11.73 ±1.55) %] (t= 7.709, P= 0.0021). The migrating cell number was decreased in hyperthermia group (25.67±4.81) than that in control group (85.00±10.31) (t=5.182, P=0.0066). The invasive cell number was also decreased in hyperthermia group (22.00±2.08) than that in control group (108.3.0±10.14) (t=8.342, P=0.0011). The expression level of LLGL1 protein in hyperthermia group was 4.2 times that in control group(t=3.028, P=0.0389). Conclusion Hyperthermia induces the cell apoptosis and inhibits migration and invasion abilities of H1299 cells, which maybe associate with increasing LLG1 expression.

International Journal of Cerebrovascular Diseases 2014;22(8):625-628
Selective serotonin reuptake inhibitors (SSRIs),a new generation of anti-depressant agent,are mainly used to treat emotional disorders in clinical practice now.Recent studies have found that SSRIs can increase neurogenesis after cerebral ischemia,promote neurovascular reconstruction,and are conducive to the recovery of neurological function.Furthermore,SSRIs can improve the tolerance of ischemic tissue,exert anti-inflammation and anti-oxidation properties,reduce the blood-brain-barrier injury,and inhibit excitatory amino acid toxicity in order to exert neuroprotective effect.This article reviews the related research progress in SSRIs and ischemic stroke.
8.Advances and clinical application of noninvasive imaging modalities in assessing right ventricular function
Chinese Journal of Interventional Imaging and Therapy 2010;7(1):78-81
Right ventricular (RV) function is very important for patients with respiratory and cardiovascular disorders resulting in RV impairments. Since RV has complex geometry of the chamber, it is difficult to accurately measure the RV volumetric parameters with conventional imaging modalities, especially those with dilated and abnormal RV. With the emergence and wide use of new noninvasive imaging modalities in accessing the cardiac anatomy and function, real-time three-dimensional echocardiography (RT3DE), multi-detector row computed tomography (MDCT) and new MRI sequences, noninvasive quantitative assessment of the RV function has attracted more and more worldwide attention.

10.Assessment of relationship among color Doppler flow pattern,vascular distribution and lymph nodes metastasis in breast carcinomas
Chinese Journal of Postgraduates of Medicine 2011;34(14):7-9
Objective To study the association among the color Doppler flow pattern, vascular distribution and the lymph nodes metastasis in breast carcinomas. Methods Sixty-eight patients with infiltrating mammary gland duct carcinoma were divided into the no-lymph-nodes-metastasis group (group I , 37 cases) and the lymph-nodes-metastasis group (group Ⅱ , 31 cases), group Ⅱ were subdivided into group Ⅱa (19 cases): lateral lymph nodes positive of pectoralis minor and group Ⅱ b (12 cases): rear of pectoralis minor and subclavian lymph node positive. Blood flow parameters [peak systoltc velocity (PSV),resistent index ( RI)] and vascular Alder grades were observed and measured with color Doppler ultrasound.The results were compared with the incidence of lymph node metastasis. Results PSV and RI were not significantly different between group Ⅰ and group Ⅱ (t = -0.19,-0.63,P> 0.05),and also between group Ⅱ a and group Ⅱ b (t =-1.12,-013,P >0.05). By using vascular Alder grades,there were no significant differences between group Ⅰ and group Ⅱ (x2= 0.46, P> 0.05 ), but the significant differences were observed between group Ⅱ a [10.5%(2/19) ,63.2%( 12/19) ,26.3%(5/19) in Alder Ⅰ , Ⅱ , Ⅲ grade] and group Ⅱ b [8.3%( 1/12), 16.7%(2/12),75.0%(9/12)in Alder Ⅰ , Ⅱ ,Ⅲ grade](x2 = 7.41,P<0.05). Conclusion The pattern of blood flow has no correlation with lymph nodes metastasis, vascular Alder grades of carcinoma shows some relevance with the lymph nodes metastasis in the patients with infiltrating mammary gland duct carcinoma.
