1.Risk factors and prevention of ischemic stroke in women
International Journal of Cerebrovascular Diseases 2014;22(7):541-545
Guidelines for the Prevention of Stroke in Women released by the American Heart Association/American Stroke Association on February 6,2014,and this makes us have further reflection on the risk factors for ischemic stroke and prevention in women.Compared with men,some of risk factors are unique for women or more common in the female population.The in-depth understanding of the risk factors is essential for the prevention of ischemic stroke in women.

This article reviewed key genes that involved in fatty acid synthesis and triacylglycerol assembly pathway. The transcription factors which play important roles in seed development and oil content were also reviewed. We summarized the achievement in modifying fatty acid composition and increase oil content in plant by gene engineering using these genes.

Objective To observe the effects of peritoneal resuscitation by pyruvate replacing lactate peritoneal dialysis solution on the intestinal mucosal barrier in rabbits with hemorrhagic shock.Methods The hemorrhagic shock model was prepared in 48 healthy male rabbits by adopting the improved Wiggers method.Then the rabbits were randomly divided into the conventional intravenous resuscitation group (group A),conventional intravenous resuscitation plus intraperitoneal injection of lactate peritoneal dialysis solution group (group B),conventional intravenous resuscitation plus intraperitoneal injection of pyruvate peritoneal dialysis solution group (group C) and intravenous pyruvate peritoneal dialysis solution resuscitation plus intraperitoneal injection of pyruvate peritoneal dialysis solution group (group D).The levels of diamine oxidase (DAO) and lipopolysaccharide (LPS) were measured before shock,at 60 min after shock,at 60,180 min after resuscitation.At the end of observation,the ileum tissues were taken from the 5 cm away from the ileocecal region for measuring the dry/wet ratio,malondialdehyde (MDA) level and superoxide dismutase (SOD) activity and their morphological changes was observed.Results There was no statistical difference in the plasma levels of DAO and LPS before shock among the four groups (P>0.05);which at 50 min after shock were increased,but the comparison among the groups had no statistical difference (P>0.05);the plasmas levels of DAO and LPS at 60,180 min after resuscitation in the group A,B,C and D were decreased in turn (P<0.05).The MDA levels of ileum tissues after 180 min of resuscitation in the group A,B,C and D were decreased in turn (P<0.05),but the SOD activties and tissue dry/wet mass ratios were increased in turn (P<005),moreover the tissue injury degrees were also relieved in turn.Conclusion The peritoneal resuscitation by pyruvate replacing lactate peritoneal dialysis solution can more effectively protect the intestinal tissue cells and reduce intestinal mucosal damage in hemorrhagic shock rabbits.

Background:
Red blood cell distribution width/platelet count ratio (RPR) is a reliable prognostic assessment indicator for numerous diseases. However, no studies to date have examined the relationship between RPR and the prognosis of diffuse large B-cell lymphoma (DLBCL).Therefore, this study aimed to investigate the correlation between RPR and the clinical characteristics and prognosis of patients with diffuse large B-cell lymphoma.
Methods:
We retrospectively studied 143 patients with newly diagnosed DLBCL and used the median value as the RPR threshold. We also investigated the correlation of pretreatment RPR level with clinical characteristics and its impact on DLBCL prognosis.
Results:
Using the median value as the cut-off, patients with DLBCL were divided into a low RPR group (<0.0549) and a high RPR group (≥0.0549). Patients in the high RPR group were older, had a later Ann Arbor stage, were prone to bone marrow invasion, and had a higher National Comprehensive Cancer Network International Prognostic Index score (P < 0.05). A survival analysis showed that progression-free survival (PFS) (P =0.003) and overall survival (OS) (P <0.0001) were significantly shorter in the high versus low RPR group. A multifactorial Cox analysis showed that bone marrow invasion and elevated lactate dehydrogenase (LDH) were separate risk factors for PFS (P <0.05), while an RPR ≥0.0549 and elevated LDH were separate risk factors for OS (P <0.05).
Conclusion
A high RPR (≥0.0549) in patients with newly diagnosed DLBCL is an independent risk factor for a poor prognosis.
