Glomerular Filtration Rate is Associated with Hemorrhagic Transformation in Acute Ischemic Stroke Patients without Thrombolytic Therapy

引用

Chinese Medical Journal 2018年第14期131卷 1639-1644页

作者： Ming-su Liu Yan liao Guang-Qin Li Department of Neurology First Affiliated Hospital of Chongqing Medical University Chongqing 400016 China Chongqing Key Laboratory of Neurobiology Chongqing 400016 China Department of Neurology Chengdu 363 Hospital of Southwest Medical University Chengdu Sichuan 610000 China

Background： Whether there is a relationship between glomerular filtration rate IGFR） and hcnlorrhagic transformation （HT） after acute ischemic stroke （A1S） is still under debate. The aim of our study was to determine whether the GFR level is a predictor of HT in AIS patients without thrombolytic therapy （TT）. Methods： Consecutive A IS patients without TT were included in this prospective study fiom January 2014 to December 2016 in the First Affiliated Hospital of Chongqiug Medical University. We divided them into two groups （HT and non-HT group） and meticulously collected baseline characteristics and laboratory and imaging data of interested individuals. Multivariate regression analysis was performed to assess the correlation between GFR and HT in stroke patients without TT. Results： Among 426 consecutive patients, 74 （17.3%） presented HT （mean age： 65 ± 12 years, number of male patients： 47） on the follow-up scans. In multivariate regression analysis, HT was significantly associated with low GFR （odds ratio [OR] = 3.708, confidence interval [CI] = 1.326-10.693, P = 0.013）, atrial fibrillation （AF; OR = 2.444, CI= 1.087-5.356, P = 0.027）, large cerebral inthrction （OR = 2.583, CI= 1.236-5.262, P= 0.010）, and hypoalbuminemia （HA OR = 4.814, CI= 1.054 22.153, P = 0.037） for AIS patients without TT. Conclusions： The present study strongly showed that lower GFR is an independently predictor of HT： in addition, large inlhrct volume, AF, and HA are also important risks of HT for AIS patients without TT, which offered a practical information that risk factors should be paid attention or eliminated to prevent HT for stroke patients though the level of evidence seems to be unstable.

AIM:To investigate the mRNA expression of cyclooxygensae-2(COX-2)in benign and malignant ascites,and to explore the difference in COX-2 mRNA expression among different ***:A total of 36 samples were collected from the Fifth Affiliated Hospital of sun Yat-Sen University and divided into two experimental groups:benign ascites(n=21)and malignant ascites(n=15).Benign ascites included cirrhotic ascites(n=10)and tuberculous ascites(n=5).Malignant ascites included oophoroma(n=7),cancer of colon(n=5),cancer of the liver(n=6),gastric cancer(n=2),and bladder carcinoma(n=1).The mRNA expression of COX-2 in ascites was examined with reverse transcriptase polymerase chain reaction(RT-PCR)technology,and the positive rate of COX-2 mRNA was compared between different ***:The positive rate of COX-2 mRNA in malignant ascites was 42.9%(9/21),which was significantly higher than in benign ascites,6.7%(1/15),difference being significant between these two groups(χ2=4.051,P=0.044).The proportion of the positive rate in the malignant ascites was as follows:ovarian cancers57.1%(4/7),colon cancer 40.0%(2/5),liver cancer33.3%(2/6),gastric cancer 50.0%(1/2),and bladder cancer 0.00%(0/1).However,there was no significant difference in COX-2 mRNA expression among various tumors with malignant ascites(χ2=1.614,P=0.806).Among the benign ascites,COX-2 mRNA levels were different between the tuberculous ascites(0/5)and cirrhotic ascites(1/10),but there was no significant difference(P=1.000).CONCLUSION:COX-2 mRNA,detected by RT-PCR,is useful in the differential diagnosis of benign and malignant ascites,which also has potential value in the clinical diagnosis of tumors.

H9N2 avian influenza virus（AIV） infection is a major problem in poultry industry worldwide. In this study, molecular characterizations and phylogenetic relationships of hemagglutinin（HA） gene sequences of H9N2 AIV of 5 Chinese isolates in 2014 recently available in Gen Bank, 3 widely used vaccine strains, and 52 novel isolates in China from 2013 to 2015 were analyzed. The homology analysis showed that the nucleotide sequences of HA gene of these recent Chinese H9N2 AIV isolates shared homologies from 94.1 to 99.9%. Phylogenetic analysis showed that all isolates belonged to AIV lineage h9.***.2.5. Fifty-six out of the 57 recent Chinese H9N2 AIV isolates had the motifs PSRSSR↓GLF at the cleavage sites within the HA protein, while one isolate PWH01 harbored LSRSSR↓GLF. Remarkably, all of the recent Chinese H9N2 AIV strains had the Q216 L substitution in the receptor binding site, which indicated that they had potential to infect humans. Most of recent Chinese H9N2 AIV isolates lost the potential N-linked glycosylation site at residues 200–202 compared with vaccine strains. This present study demonstrated that AIV lineage h9.***.2.5 was more predominant in China than other lineages as it harbored all the H9N2 AIV isolated between 2013 and 2015. Also we showed the importance of continuous surveillance of emerging H9N2 AIV in China and update of vaccine formulation accordingly in order to prevent and control H9N2 AIV.
