4Coseismic vertical deformation of the M_S8.0 Wenchuan earthquake from repeated levelings and its constraint on listric fault geometry显示文摘The devastating MS8.0 Wenchuan earthquake ruptured two large parallel thrust faults along the middle segment of the Longmenshan thrust belt.Preseismic and postseismic leveling data indicated the hanging wall of the YingxiuBeichuan-Nanba thrust fault mainly presented coseismic uplift with respect to the reference point at Pingwu county town, and the observed maximum uplift of 4.7 m is located at Beichuan county(Qushan town)which is about 100 m west of the fault scarp.The foot wall of the Yingxiu-Beichuan-Nanba thrust fault mainly showed subsidence with maximum subsidence of 0.6 m near the rupture.By employing a listric dislocation model,we found that the fault geometry model of exponential dip angleδ=88°×[1-exp(-9/h)]with depth of 18 km and uniform thrust-slip of 5.6 m could fit the observed coseismic vertical deformation very well,which verifies the listric thrust model of the Longmenshan orogenic zone.Qingliang Wang Duxin Cui Xi Zhang Wenping Wang Jinwen Liu Kang Tian Zhaoshan Song 2009Earthquake Science2009,22,6:25
5Anti-cd TCR antibody-expanded cd T cells:a better choice for the adoptive immunotherapy of lymphoid malignancies显示文摘Cell-based immunotherapy for lymphoid malignancies has gained increasing attention as patients develop resistance to conventional treatments.cd T cells,which have major histocompatibility complex(MHC)-unrestricted lytic activity,have become a promising candidate population for adoptive cell transfer therapy.We previously established a stable condition for expanding cd T cells by using anti-cd T-cell receptor(TCR)antibody.In this study,we found that adoptive transfer of the expanded cd T cells to Daudi lymphoma-bearing nude mice significantly prolonged the survival time of the mice and improved their living status.We further investigated the characteristics of these antibody-expanded cd T cells compared to the more commonly used phosphoantigen-expanded cd T cells and evaluated the feasibility of employing them in the treatment of lymphoid malignancies.Slow but sustained proliferation of human peripheral blood cd T cells was observed upon stimulation with anti-cd TCR antibody.Compared to phosphoantigen-stimulated cd T cells,the antibody-expanded cells manifested similar functional phenotypes and cytotoxic activity towards lymphoma cell lines.It is noteworthy that the anti-cd TCR antibody could expand both the Vd1 and Vd2 subsets of cd T cells.The in vitro-expanded Vd1 T cells displayed comparable tumour cell-killing activity to Vd2 T cells.Importantly,owing to higher C–C chemokine receptor 4(CCR4)and CCR8 expression,the Vd1 T cells were more prone to infiltrate CCL17-or CCL22-expressing lymphomas than the Vd2 T cells.Characterizing the peripheral blood cd T cells from lymphoma patients further confirmed that the anti-cd TCR antibody-expanded cd T cells could be a more efficacious choice for the treatment of lymphoid malignancies than phosphoantigen-expanded cd T cells.Jianhua Zhou Ning Kang Lianxian Cui Denian Ba Wei He 2012Cellular & Molecular Immunology2012,9,1:17
6GJB2 mutation spectrum in deaf population in a typical southeastern area of China显示文摘Mutations in GJB2 gene are the most frequently found mutations in patients with nonsyndromic hearing impairment. However, the spectrum and prevalence of mutations in this gene vary among different ethnic groups. In China, 30,000 infants are born with congenital hearing impairment annually. In order to provide appropriate genetic testing and counseling to the families, we investigated the molecular etiology of nonsyndromic deafness in 103 unrelated school children attending Nantong School for the Deaf and Mute in Jiangsu Province, China. The coding exon of the GJB2 gene was PCR amplified and sequenced. Sixty two GJB2 mutant alleles were identified in 35.9% (37/103) of the patients. Twenty five patients carried two pathogenic mutations and 12 patients carried one mutant allele. The 235delC was the most common mutation accounting for 69.4% (43/62) of GJB2 mutant alleles. The GJB2 mutant alleles accounted for 30.1% (62/206) of all chromosomes responsible for nonsyndromic hearing impairment. Testing of the 3 most prevalent deleterious frame shift mutations in this cohort detected 100% of all GJB2 mutant alleles. These results demonstrate that an effective genetic testing of GJB2 gene for patients and families with nonsyndromic hearing impairment is possible.DAI Pu1*, YOU Yi-wen2*, CUI Jing-hong2*, YU Fei1, HAN Bing 1, KANG Dong-yang1, YUAN Hui-jun1, HAN Dong-yi1, 1.

9Exogenous pancreatic kininogenase protects against renal fibrosis in rat model of unilateral ureteral obstruction显示文摘Tissue kallikrein has protective function against various types of injury.In this study,we investigated whether exogenous pancreatic kininogenase(PK)conferred renoprotection in a rat model of unilateral ureteral obstruction(UUO)and H2O2-treated HK-2 cells in vitro.SD rats were subjected to UUO surgery,then PK(7.2 U/g per day,ip)was administered for 7 or 14 days.After the treatment,rats were euthanized;the obstructed kidneys were harvested for further examination.We found that PK administration significantly attenuated interstitial inflammation and fibrosis,and downregulated the expression of proinflammatory(MCP-1,TLR-2,and OPN)and profibrotic(TGF-β1 and CTGF)cytokines in obstructed kidney.UUO-induced oxidative stress,closely associated with excessive apoptotic cell death and autophagy via PI3K/AKT/FoxO1a signaling,which were abolished by PK administration.We further showed that PK administration increased the expression of bradykinin receptors 1 and 2(B1R and B2R)mRNA and the production of NO and cAMP in kidney tissues.Coadministration with either B1R antagonist(des-Arg9-[Leu8]-bradykinin)or B2R antagonist(icatibant)abrogated the renoprotective effects of PK,and reduced the levels of NO and cAMP in obstructed kidney.In H2O2-treated HK-2 cells,addition of PK(6 pg/mL)significantly decreased ROS production,regulated the expression of oxidant and antioxidant enzymes,suppressed the expression of TGF-β1 and MCP-1,and inhibited cell apoptosis.Our data demonstrate that PK treatment protects against the progression of renal fibrosis in obstructed kidneys.Li-zhe Jin Hui-ying Li Jian Jin Shang-guo Piao Xiong-hu Shen Yan-ling Wu Jia-chong Xu Long-ye Zhang Yu-ji Jiang Hai-lan Zheng Ying-shun Jin Sheng Cui Kang Luo Yi Quan Can Li 2020Acta Pharmacologica Sinica2020,41,12:9
10Prevention and control of HIV/AIDS in China:lessons from the past three decades显示文摘In the past 37 years,human immunodeficiency virus/acquired immunodeficiency syndrome(HIV/AIDS)has undergone various major transmission routes in China,with the world most complex co-circulating HIV-1 subtypes,even the prevalence is still low.In response to the first epidemic outbreak of HIV in injecting drug users and the second one by illegal commercial blood collection,China issued the Anti-Drug Law and launched the Blood Donation Act and nationwide nucleic acid testing,which has avoided 98,232 to 211,200 estimated infections and almost ended the blood product-related infection.China has been providing free antiretroviral therapy(ART)since 2003,which covered>80%of the identified patients and achieved a viral suppression rate of 91%.To bend the curve of increasing the disease burden of HIV and finally end the epidemic,China should consider constraining HIV spread through sexual transmission,narrowing the gaps in identifying HIV cases,and the long-term effectiveness and safety of ART in the future.Jun-Jie Xu Meng-Jie Han Yong-Jun Jiang Hai-Bo Ding Xi Li Xiao-Xu Han Fan Lv Qing-Feng Chen Zi-Ning Zhang Hua-Lu Cui Wen-Qing Geng Jing Zhang Qi Wang Jing Kang Xiao-Lin Li Hong Sun Ya-Jing Fu Ming-Hui An Qing-Hai Hu Zhen-Xing Chu Ying-Jie Liu Hong Shang 2021Chinese Medical Journal2021,,23:9
11Screening serum hepatocellular carcinoma-associated proteins by SELDI-based protein spectrum analysis显示文摘AIM:To find out potential serum hepatocellular carcinoma (HCC)-associated proteins with low molecular weight and low abundance by SELDI-based serum protein spectra analysis, that will have much application in the diagnosis or differentiated diagnosis of HCC, as well as giving a better understanding of the mechanism of hepato-carcinogenesis. METHODS:Total serum samples were collected with informed consent from 81 HCC patients with HBV(+)/ cirrhosis(+), 36 cirrhosis patients and 43 chronic hepatitis B patients. Serum protein fingerprint profiles were first generated by selected WCX2 protein chip capture integrating with SELDI-TOF-MS, then normalized and aligned by Ciphergen SELDI Software 3.1.1 with Biomarker Wizard. Comparative analysis of the intensity of corresponding protein fingerprint peaks in normalized protein spectra, some protein peaks with significant difference between HCC and cirrhosis or chronic hepatitis B were found. RESULTS:One hundred and twenty-eight serum protein peaks between 2000 and 30 000Da were identified under the condition of signal-to-noise > 5 and minimum threshold for cluster > 20%. Eighty-seven of these proteins were showed significant differences in intensity between HCC and cirrhosis (P < 0.05). Of the above differential proteins, 45 proteins had changes greater than two-fold, including 15 upregulated proteins and 30 downregulated proteins in HCC serum. Between HCC and chronic hepatitis B, 9 of 52 differential proteins (P < 0.05) had intensities of more than two-fold, including 2 upregulated proteins and 7 downregulated proteins in HCC serum. Between cirrhosis and chronic hepatitis B, 28 of 79 significant differential proteins (P < 0.05) changes greater than two-fold in intensity, including 17 upregulated proteins and 11 downregulated proteins in cirrhosis serum. For the analysis of these leading differential proteins in subtraction difference mode among three diseases, the five common downregulated proteins in HCC serum (M/Z 2870, 3941, 2688, 3165, 5483) and two common upregulated proteins (M/Z 3588, 2017) in HCC and cirrhosis serum were screened.CONCLUSION:Because the interference of unspecific secreted proteins from hepatitis B and cirrhosis could be eliminated partly in HCC serum under subtraction difference analysis, these seven common differential proteins have the obvious advantage of specificity for evaluating the pathological state of HCC and might become novel candidate biomarkers in the diagnosis of HCC.Jie-Feng Cui Yin-Kun Liu Hai-Jun Zhou Xiao-Nan Kang Cheng Huang Yi-Feng He Zhao-You Tang Toshimasa Uemura 2008World Journal of Gastroenterology2008,14,8:8
12Optimization of Protein Extraction and Decoloration Conditions for Tea Residues显示文摘To optimize alkaline method for extracting proteins from tea residue(TR), the effect of extraction conditions on tea protein extraction rate(TPER) was investigated. Single factor experiment showed the extraction temperature 80 °C, extraction time 100 min, p H value 13 and liquid–solid ratio 40:1 as the optimal extraction conditions. The orthogonal test revealed that the maximum TPER reached 29.71% under the following optimal combination of conditions: extraction temperature 70 °C, extraction time 60 min, p H 12 and liquid–solid ratio 50:1. For optimizing the purification of tea residue proteins, isoelectric point precipitation(p I), ammonium sulfate precipitation(a S) and isoelectric point plus ammonium sulfate precipitation(i PAS) were compared. The result showed that the highest protein precipitation rate(PPR) was 89.70% which was generated by using i PAS. Furthermore, powdered activated carbon was chosen as the most suitable decolorant for the extracted proteins.CUI Qiaoyun NI Xinghong ZENG Liang TU Zheng LI Jin SUN Kang CHEN Xuan LI Xinghui 2017Horticultural Plant Journal2017,3,4:8

16Analysis and construction status of SG-Ⅱ 5PW laser facility显示文摘We present a recent progress of the SG-II 5 PW facility, which designed a multi-petawatt ultrashort pulse laser based on optical parametric chirped-pulse amplification(OPCPA). The prior two optical parametric amplifiers have been accomplished and chirped pulses with an energy of 49.7 J and a full-width-at-half-maximum(FWHM) spectrum bandwidth of 85 nm have been achieved. In the PW-scale optical parametric amplification(OPA), with the pump pulse that has an energy of 118 J from the second harmonic generation of the SG-II 7 th beam, the pump-to-signal conversion efficiency is up to 41.9%, which to the best of our knowledge is the highest among all of the reported values for OPCPA systems. The compressed pulse is higher than 37 J in 21 fs(1.76 PW), and the focal spot is ~10 μm after the closed-loop corrections by the adaptive optics. Limited by the repetition of the pump laser, the SG-II 5 PW facility operates one shot per hour. It has successfully been employed for high energy physics experiments.Jianqiang Zhu Xinglong Xie Meizhi Sun Jun Kang Qingwei Yang Ailin Guo Haidong Zhu Ping Zhu Qi Gao Xiao Liang Ziruo Cui Shunhua Yang Cheng Zhang Zunqi Lin 2018High Power Laser Science and Engineering2018,6,2:7

19An experimental and numerical study of the freak wave speed显示文摘The propagation speed is one of the most important characteristics for describing freak waves. The research of freak wave speed is not only helpful for understanding the generation mechanism and evolution process of freak waves, but also applicable to the prediction. A stable and accurate method is proposed for the calculation of the freak wave speed, in which physical model tests are carried out to measure the motion of the largest wave crest along the wave tank. The linear regression relationship between the spatial position of the largest wave crest and instantaneous moment is established to calculate the speed of totally 248 cases of experimental freak waves and 312 supplementary cases of numerical freak waves. Based on the calculate results, a semitheoretical and semiempirical formula is proposed by using a regression analysis method to predict the speed of the freak wave, and the nonlinear characteristic of the freak wave speed is also investigated.CUI Cheng ZHANG Ningchuan KANG Haigui YU Yuxiu 2013Acta Oceanologica Sinica2013,32,5:7
