Background and purpose:Ara-C is one of the most effective and common agents in the treatment of acute nonlyphocytic leukemia. Telomerase is a unique complex of ribonucleoprotein. It plays an important role in the pathogenesis and development of cancer. In this study, we investigate the changes of mRNA expression of telomerase subunits in HL-60 cells induced by Ara-c and try to come up with a theory that could help to assess the efficacy of Ara-C. Methods:The combinations of various Ara-C concentration and the incubation time were used to treat HL-60. The ratios of apoptotic cell to necrosis cell were determined by flow cytometry and the expressions of telomerase subunits mRNA were evaluated by RT-PCR.Results:① There was no influence on transcription of telomerase subunits gene after HL-60 cells was cultured with 0~0.2ug/ml Ara-C for 12 hours;② 2ug/ml and 10ug/ml of Ara-C could down regulate the expression of hTERT from 0.80+0.07 to 0.50+0.04 and 0.39+0.03, not hTR and hTP1;③ with longer incubation with 10ug/ml of Ara-C, the percentage of apoptosis could be increased. The maximal induction of apoptosis (18.16+4.25%) could be reached at 12hrs treatment of Ara-C, then gradually decreased later on. The rate of necrosis increased with time, the maximal percentage(57.94+12.03%) of necrosis was observed at 48hrs of incubation time with drug. The mRNA level of hTERT gene also decreased along with the cultured time , the lowest value (0.18+0.03) has been documented at 48hrs time point, but not hTR、TP1.Conclusions:① Ara-C could down-regulate the expression of hTERT mRNA in a dose-and time-dependent manner, but not hTR、hTP1;② There might be no relationship between the percentage of apoptosis induced by Ara-C apoptosis and the expression of telomerase hTERT gene mRNA, but a close relationship between necrosis and the expression of hTERT mRNA has been found.

Phthaloyl dichloride (1)was reacted with LiAlSeH2 to give benzo[c]selenophene-1;3-dione (2);which was treated with the Grignard reagents to generate hydroxyl compounds 3a-3h.These compounds were finally converted to target products 4a-4h by treatment with hydriodic acid.The structures of 4a-4h were confirmed by MS and 1 H NMR.Their inhibitory activity against adenosine diphosphate (ADP)-induced platelet aggregation was evaluated by Born′s turbidimetric assay;free radical scavenging activity was assayed by xanthine oxidasemethod and 1;10-phenanthroline spectrophotometric method.It was found that compound 4 f displayed more potent inhibi-tory effect on platelet aggregation than 3-n-butylphthalide and comparable hydroxyl free radical scavenging activity in vitro to that of edaravone.Therefore;compound 4 f might be the candidate for further investigation.

Objective To explore the predictive value of brain lobe location of stroke lesion to development of long-term post-stroke depression(PSD)in the first-episode ischemic stroke patients for providing evidence for early intervention.Methods In the prospective study,158 patients aged 60 and over with first-episode ischemic stroke were continuously admitted into Department of Neurology of Shangqiu First People's Hospital from January 2013 to July 2013.The 2 to 3 years follow-up after stroke episode was performed in 126 cases for inquiring into correlation between brain lobe location of stroke lesion and development of PSD.The diagnosis of depression was in accordance with Mental Disorders Diagnostic and Statistical Manual 4(DSM-Ⅳ)standard,and divided into groups of stroke with depression(n=52)and stroke without depression(n=74).The degree of depression was evaluated by 17-item Hamilton Rating Scale for Depression(HAMD17).The location,number and volume of stroke lesions were determined by head MRI.The relationship between PSD and pathogenetic loci was analyzed by unconditional Logistic regression analysis.A difference in hemisphere commensalism.Results The morbidity of PSD was 41.3%(52/126),with 21.4%(27/126),12.7%(16/126),7.1%(9/126)in mild,moderate and severe PSD respectively.The frontal lobe(OR=2.824,95%CI=1.189-6.706)and the temporal lobe(OR=3.579,95%CI=1.233-10.393)cerebral infarction were correlated with the occurrence of PSD.The long-term PSD severity was more in frontal lobe than in temporal lobe(χ2=6.399,P<0.05).The average volume of cerebral infarction was larger in PSD group than in non-PSD group(t=3.271,P<0.05),and the average number of cerebral infarction loci was more in PSD group than in non-PSD group(t=3.176,P<0.05).The more severe the degree of depression according to HAMD17,the larger the average volume of cerebral infarction(F=6.280,P<0.05)and the more the average number of lesions(F=6.132,P<0.05).Conclusions The development of long-term PSD in the first-episode elderly patients is affected by the invasion site.The frontal lobe and temporal lobe infarction are independent risk factors for long-term PSD in patients with ischemic stroke,and the PSD was more severe in frontal lobe infarction than in temporal lobe infarction.

Objective To explore the characteristics of dipyridamole 201 Tl myocardial perfusion imaging (MPI) SPECT in patients with dilated cardiomyopathy. Methods Thirty patients with dilated cardiomyopathy underwent pharmacological stress 201Tl MPI SPECT after intravenous infusion of dipyridamole (0. 56 mg/kg) for 4 min. The early and delayed SPECT images were acquired respectively at 10 and 240 min after 201Tl injection. The images were analyzed and reported by two or three experienced nuclear medicine physicians. Results All patients were found to have abnormal perfusion patterns at delay imaging, however 90.00% (27/30) were also abnormal at early images. Six patients had reverse redistribution. Conclusion Dipyridamole 201Tl MPI SPECT imaging may be of some value for the assessment of patients with dilated cardiomyopathy.
