Objective: To investigate the effects of carotid arteriosclerosis on cognitive functions and current prognosis in patients with cerebral infarction. Methods: Extracranial carotid arteries were assessed using dopple ultrasongraphy in 112 patients with cerebral infarction. Cognitive functions were evaluated with the Mini-Mental state Examination (MMSE) and five neuropsychological tests assessing memory, attention, calculation psychomotor rapidity and visuospatial perception. Deficits in neurological functions were assessed on admission and 3 to 4 weeks. Results:All neuropsychological measures were found to be poorer in patients with carotid arteriosclerosis than those with no carotid arteriosclerosis, especially in cases with severe carotid arteriosclerosis and severe carotid stenosis. There was a positive relationship between severity of carotid arteriosclerosis and change in cognitive functions. The scores of SSS were higher on admission in cerebral infarction patients with carotid arteriosclerosis. Recent prognosis was also poorer in patients with carotid arteriosclerosis.Conclusions: Significant effect of carotid arteriosclerosis was shown on cognitive functions of patients with cerebral infarction. As cerebral ischemic injury is severe, prognosis in cerebral infarction patients with carotid arteriosclerosis is poor.

Objective To study the clinical significance of carotid atherosclerosis and the relationship between carotid atherosclerosis and cerebral infarction recurrence.Methods Carotid atherosclerosis was assessed using doppler ultrasongraphy in 312 patients with cerebral infarction, the duration of following up was 12 to 18 months,and the characteristics of carotid atherosclersis was compared to patients with or without recurrence cerebral infarction.Results Of the 312 patients with cerebral infarction, 61 patients suffered from new cerebral infarction during following up period, the recurrence rate in patients with atherothrombotic brain infarction was higher than those with lacunar infarction, and the cerebral infarction recurrence usually occurred in the same side of initial stroke of the 57 patients with severe carotid atherosclerosis, 26 patients had a sufference of new infarction, of the 48 patients with high grade stenosis, 25 had a sufference of new cerebral infarction, of the 42 patients with ulcerated plaque, 23 had sufference of new cerebral infarction,showing a recurrence rate significantly higher than those patients with non carotid atherosclerosis or those with mild carotid atherosclerosis. The logistic regression analysis showed that the levels of carotid atheroslerosis , stenosis and ulcerated plaque were positively related to the cerebral infarction recurrence.Conclusions There is a positively relationship between carotid atherosclerosis and cerebral infarction recuurrence, and the level of carotid atherosclerosis is a risk factor of cerebral infarction recurrence.It serves as a risk marker of cerebral infarction recurrence.

ObjectiveTo investigate the role of ischemic postconditioning on lung ischemic/reperfusion injury induced by cardiopulmonary bypass (CPB) in combined mitral and aortic valve replacement,and evaluate the effects of different protocol of ischemic postconditioning,and analyze its possible mechanisms.Methods24 patients diagnosed as rheumatic mitral and aortic valve disease with or without tricuspid valve disease were randomly divided into 3 groups (8 in each):Control group( group A),patients undergoing routine cardiac surgery; Postconditioning group Ⅰ (group B ),patients undergoing routine cardiac surgery and ischemic postconditioning by occlusion of the pulmonary artery of five cycles of 15 s ischemia and 15 s repeffusion before the pulmonary artery totally restoring peffusion; Postconditioning group Ⅱ (group C),patients undergoing routine cardiac surgery and ischemic postconditioning by occlusion of the pulmonary artery of five cycles of 30 s ischemia and 30 s repeffusion before the pulmonary artery totally restoring perfusion.The Oxygenation Index (OI) was measured at pre -operation and 1 h,2 h,3 h,6 h and 12 h after terminating CPB.The plasma contents of MDA were detected by Enzyme-linked Immunosorbent Assay at pre -operation,1 h,3 h,6 h and 12 h after terminating CPB.ResultsCompared with group A and C,OI in group B significantly increased at 1 h,2 h,3 h,6 h after terminating CPB (283.25 ±56.47 vs 384.76 ±29.17 vs 310.50 ±65.71,265.75 ±58.78 vs 381.75 ±29.67 vs 310.50 ±48.17,283.75 ±73.15 vs389.74±39.34 vs 317.87 ±78.41,310.37 ±52.00 vs 401.62 ±4 2.89 vs 337.25 ± 64.06,all P ＜0.05),and the plasma contents of MDA in group B reduced at 1 h,3 h,6 h,12 h after terminating CPB (4.64±0.63 vs 3.88 ±0.20 vs 4.38 ±0.41,5.75±0.49 vs 4.44 ±0.34 vs 5.28 ±0.76,4.42±0.31vs 3.77 ± 0.40 vs 4.35 ± 0.54,3.74 ± 0.31 vs 3.19 ± 0.17 vs 3.64 ± 0.24,all P ＜ 0.05 ), However,there were no significant differences in OI and MDA between group C and A (all P ＞0.05 ).Conclusions Ischemic postconditioning by occlusion of the pulmonary artery of 5 cycles of 15 s ischemia and 15 s reperfusion attenuates lung oxygenation function injury induced by CPB in double valves replacement,and it is possibly mediated by reducing MDA produced by lipid peroxidation.However,ischemic postconditioning by occlusion of the pulmonary artery of 5 cycles of 30 s ischemia and 30 s repeffusion may not have significant protective effect for lung oxygenation function injury induced by CPB in double valves replacement.

Abstract: Total RNA was isolated from Siraitia grosvenorii fruit by the method of modified Trizol, according to S. grosvenorii fruit characteristics of rich phenols, polysaccharide, oil and proteins. The OD260/280, OD260/230, RNA integrity (RIN) and yield of the total RNA with this method were 2.01, 2.02, 9.50 and 260 mirog.g-1, respectively. The open reading frame (ORF) of dehydroascorbate reductase (DHAR), named as SgDHAR, was cloned by rapid amplification of cDNA ends (RACE) and RT-PCR method from S. grosvenorii. The GenBank accession number for this gene is KC907731. The SgDHAR gene contains a full-length cDNA of 1,252 bp including ORF of 819 bp and encodes a predicted protein of 272 amino acids. The molecular mass is 30.217 7 kD and the isoelectric point is 8.76. Homology comparison showed that it shared 87% nucleotide sequence homology with Cucumis sativus. Expression patterns using qRT-PCR analysis showed that SgDHAR was mainly expressed in fruit and stem, followed by flower, and was lowest in root, while the expression level was 6.83 times in triploid. T than that in diploid. Therefore, SgDHAR gene may be involved in abortion of triploid seedless S. grosvenorii.

0.05), and the total score were similar in the two groups. Type Ⅱ collagen in the two groups was strongly positive by immunohistochemistry staining. CONCLUSION: Cryopreserved allogenic osteochondral pillars transplantation can repair small full-thickness articular cartilage defects. The chondrocytes are alive in short time, and they can secret cartilage matrix without obvious rejection. It has similar efficacy in histology with autogenic osteochondral pillar transplantation.

CYP450 plays an essential role in the development and growth of the fruits of. However, little is known about thegene in. Here, based on transcriptome data, a full-length cDNA sequence ofwas cloned by reverse transcriptase-polymerase chain reaction (RT-PCR) and rapid-amplification of cDNA ends (RACE) strategies.is 1677 bp in length (GenBank accession No. AEM42985.1) and contains a complete open reading frame (ORF) of 1422 bp. The deduced protein was composed of 473 amino acids, the molecular weight is 54.01 kDa, the theoretical isoelectric point (PI) is 8.8, and the protein was predicted to possess cytochrome P450 domains.gene was highly expressed in root, diploid fruit and fruit treated with hormone and pollination. At 10 days after treatment with pollination and hormones, the expression of Sghad the highest level and then decreased over time, which was consistent with the development of fruits of. Hormonal treatment could significantly induce the expression of. These results provide a reference for regulation of fruit development and the use of parthenocarpy to generate seedless fruit, and provide a scientific basis for the production of growth regulator application agents.
