We investigate high time resolution data obtained by the Gravitational wave high-energy Electromagnetic Counterpart All-sky Monitor(GECAM)during the flare event on 2022 April 21 at 01:52 *** subpeaks with durations of 4-6 s have been detected in the hard X-ray precursor phase,and the key feature is that they appear in pairs and seem like double-peak *** subpeaks are rarely observed in hard X-ray band and confirmed by the microwave obtained by Nobeyama Radio Polarimeters(NoRP)and Radio Solar Telescope Network(RSTN).While an exponential function can describe the continuum component of the time profile from the precursor to part of the impulsive *** periods of quasi-periodic pulsations(QPPs)are detected to be about 7.3 and 12.8 s for the precursor and impulsive phase,respectively,with at least 95%confidence *** paired QPPs are assumed to be double-peak QPPs and then the scenario of current loop coalescence model is found to be in good agreement with our *** precursor phase can be interpreted as the oscillating coalescence of two islands,while the impulsive phase can be interpreted as more islands to coalesce one by one to form larger islands.

引用

World Journal of Gastroenterology 2008年第10期14卷 1612-1616页

作者： Lin-Bo wang Zhi-Nong jiang Miao-Ying Fan Chao-Yang Xu Wen-Jun Chen jian-guo Shen Department of Surgical Oncology Sir Run Run Shaw Hospital Zhejiang University College of Medicine Hangzhou 310016 Zhejiang Province China Department of Pathology Sir Run Run Shaw Hospital Zhejiang University College of Medicine Hangzhou 310016 Zhejiang Province China Department of Ultrasonic Diagnostics Sir Run Run Shaw Hospital Zhejiang University College of Medicine Hangzhou 310016 Zhejiang Province China

AIM: To investigate the changes of histology and expression of MMP-2 and nm23-H1 in primary and metastatic gastric cancer. METHODS: One hundred and seventy-seven gastric cancer patients with lymph node and/or distal metastasis between 1997 and 2001 were reviewed. Differences in histology of the primary and metastatic gastric cancer were assessed. MMP-2 and nm23-H1 immunoreactivity was compared in 44 patients with tumor infiltration to the serosa layer. RESULTS: Poorly and moderately differentiated metastatic gastric cancer was found in 88.7% (157/177) and primary gastric cancer in 75.7% (134/177) of the patients. The histological type of metastatic gastric cancer that was not completely in accordance with the preponderant histology of primary gastric cancer was observed in 25 patients (14.1%). MMP-2 immunoreactivity in metastatic gastric cancer was significantly stronger than that in primary gastric cancer, while nm23-H1 immunoreactivity showed no difference in primary and metastatic gastric cancer. CONCLUSION: Metastatic gastric cancer presents more aggressive histological morphology and higher MMP-2 immunoreactivity than primary gastric cancer. This heterogeneity may elicit a possible mechanism of gastric cancer metastasis.

Expression of FLICE-inhibitory Protein in Synovial Tissue and Its Association with Synovial Inflammation in Juvenile Idiopathic Arthritis

引用

Chinese Medical Sciences Journal 2010年第1期25卷 20-26页

作者： Feng-xia Wu Li-jun Wu Xiong-yan Luo Ming-hui Yang Zhong Tang Chuan-mei Xie Jing-guo Zhou jian-long Guan guo-hua Yuan Institute of Rheumatology and Immunology Affiliated Hospital of North Sichuan Medical College Nanchong Sichuan 637000 China Department of Rheumatology People＇s Hosptial of Xinjiang Uygur Autonomus Region Urumchi 830001 China Department of Rheumatology and Immunology Changhai Hospital Second Military Medical University Shanghai 200433 China

Objective To examine the expression of FLICE-inhibitory protein (FLIP) in juvenile idiopathic arthritis (JIA) and analyze its correlation with synovial inflammation. Methods The expression of FLIP was assessed in 11 JIA and 3 normal synovial tissue samples by reverse transcription-polymerase chain reaction (RT-PCR) and immunohistochemistry. The cell types expressing FLIP were further characterized,and the correlation of FLIP expression with the degree of synovial inflammation,as well as the activity of caspase 8 was then analyzed. Results RT-PCR revealed the expression of FLIP mRNA in all 11 JIA samples,but not in 3 normal synovial tissues. In JIA,FLIP expression could be found in both the lining and sublining layers,mainly in the macrophage-like cells. Moreover,the expression of FLIP in JIA synovial tissues was positively correlated with the degree of synovial inflammation (r=0.563,P<0.05). Conclusion The expression of antiapoptotic FLIP in JIA synovial tissue and its correlation to accumulation of inflammatory cells in synovial tissue suggests that FLIP potentially extends the lifespan of synovial cells and thus contributes to the progression of joint destruction.

Symptomatic osteonecrosis of the femoral head after adult orthotopic liver transplantation

引用

Chinese Medical Journal 2012年第14期125卷 2422-2426页

作者： LI Hua ZHANG jian HE Ji-wen wang Kun wang Gen-shu jianG Nan FU Bin-sheng wang guo-ying YANG Yang CHEN Gui-hua Department of Hepatic Surgery Department of Orthopedic Surgery Department of Orthopedic. Surgery

Background With the increase of survival in liver transplantation recipients, more patients are at a high risk of developing osteonecrosis, especially in the femoral head, due to immunosuppressive treatment. The purpose of this study was to report the incidence, possible risk factors, and outcome of symptomatic osteonecrosis of the femoral head （ONFH） in adult patients with current immunosuppressive agents and individual protocol after liver transplantation in China. Methods A retrospective analysis was performed on 226 adult patients who underwent orthotopic liver transplantation （OLT） at a single liver transplantation institution between January 2004 and December 2008. The posttransplant survival time （or pre-retransplantation survival time） of all the patients were more than 24 months. The possible pre- and post-transplantation risk factors of symptomatic ONFH were investigated and the curative effects of the treatment were also reported. Results The incidence of ONFH was 1.33% in patients after OLT. ONFH occurred at a mean of （14＋6） months （range, 10-21 months） after transplantation. Male patients more often presented with osteonecrosis as a complication than female patients. The patients with lower pre-transplantation total bilirubin and direct bilirubin levels （P 〈0.05）. There was no difference in the cumulative dose of corticosteroids or tacrolimus between the patients with or without symptomatic ONFH. Patients were treated either pharmacologically or surgically. All patients showed a nice curative effect without major complications during the 18-63 months post-treatment follow up. Conclusions The symptomatic ONFH does not occur commonly after adult OLT in the current individual immunosuppressive protocol in China.
