Objective To observe the change of door-to-needle time(DNT)and the intravenous thrombolysis rate by recombi-nant tissue plasminogen activator(rt-PA)in the patients with acute ischemic stroke (AIS)after establishing and perfecting the stroke green channel in our hospital.Methods A total of 3 990 patients with AIS in our hospital since 2010 were screened for the statistics on the number of the patients within the time window every year,conducting the analysis on the change trend of the annu-al intravenous thrombolysis rate and DNT.The change situation of DNT and the annual intravenous thrombolysis rate change were compared before the establishment of the stroke green channel and after the establishment and the continuous improvement of the stroke green channel.Results The proportion of AIS patients within the time window in our hospital was significantly lower than that in the domestic developed regions.The intravenous thrombolysis rate by rt-PA achieved the zero breakthrough since the estab-lishment of the stroke green channel in 2011.Along with the continuous improvement of the stroke green channel,the DNT median of the patients within the time window was reduced to 60 min in 2012 and 53.5 min in 2013,moreover the intravenous thrombolysis rate by rt-PA in the patients within the time window was increased from 0 in 2010 to 74.3% in 2013.Conclusion By gradually per-fecting the process of the stroke green channel and strengthening the cooperation of emergency,clinical laboratory and stroke team, DNT is reduced by a large margin and the intravenous thrombolysis rate is substantially increased,which indicates that establishing the perfecting and smooth stroke green channel in the serious pre-hospital delay areas is a necessary measure for increasing the in-travenous thrombolysis rate.

Allogeneic stem cell transplantation (allo-HSCT) is probably the only treatment for multiple myeloma (MM) with a curative potential.However,the application of allo-HSCT is limited by the high transplant-related mortality (TRM).Although the introduction of reduced intensity conditioning (RIC) has lowered the TRM associated with myeloablative conditioning,there is no improvement in survival of allo-RIC compared to autologous stem cell transplantation (auto-HSCT).New strategies are discussed with the aim of lowering transplant toxicity and boosting the graft-versus-myeloma effect,and these are urgently needed to make allo-RIC safer and more effective for myeloma patients.In this review,results from studies of allo-HSCT in MM are presented.

Up to now,one transketolase (TKT) and two transketolase-like genes (TKTL1 and TKTL2) have been identified in the human genome.People have conducted a series of basic and clinical researches of TKTL1 in malignant neoplasms since Coy found TKTL1 has a high expression of protein and gene levels in the malignant tumors in 2005.Although the biochemical and functional mechanism have not been clarified clearly,a positive role of TKTL1 in promoting tumorigenesis and tumor progression has been proved.

The periodontal regeneration is based on the proliferation and mult-differentiation of periodontal ligament cells.Thus,to find a method of enhancing the differentiation of periodontal ligament cells has been a hot point in studying periodontal disease.Many bioactive factors have important effects on the periodontal regeneration. Growth factors as bioactive factors have promotion effects on migration,growth,proliferation,differentiation,and protein synthesis.

DNA methylation is a way of regulating gene expression of eukaryotes. DNA methylation in the regulation of normal cell development and cancer play an important role. There is evidence that in cancer patients compared with normal subjects,the former showed higher tumor suppressor gene methylation and cancer gene abnormality hypomethylation. In a variety of cancer types, related genes that can control cell cycle, proliferation, apoptosis ,metastasis,drug resistance and intracellular signal transduction exsist abnomal methylation.

physiological criteria of seaman in hot enviroment on J506 ship during the voyage on the tropics was investigated in May, 1980. It was found that the 6 physiological heat criteria(body temperature, pulse rate, electrocardiogram, 3 hours-sweat, urinary salt and the quantity of 24 hours-urine)were within the tolerable limits at the ordinary works, and the cabin temperature was not more than 32℃ (WBGT).The body temperature and pulse rate elevated when the workload increased.When the ship transfer from the high latitudes to the low latitudes in a short time,it is advised to a heat acclimatization, otherwise, the heat damags even heat stroke would occur.The water and electrolytes of the seaman was maintained in balance on the voyage. No special supplement was needed.

The toxic effect of boron on Langerhans' islands was studied with insulin radio-immunoassay.The results were as follows : the blood sugar decreased and the level of blood insulin increased in the experimental group (taking boron 30mg/kg body weight per day for 96 days),compared to those in the control group,and a deviating phenomenon of excretion curves occurred.The results suggest that boron may have a toxic effect on ?-cells of Langerhans islands,which leads to an increase in blood insulin and a decrease in blood sugar,and Langerhans' islands may be relatively sensitive target organs.This study will be of some value in making the criterion of boron concentration in drinking water for short term consumption of troops in war.

The plasticity of bone marrow stem cells is an important discovery in the field of stem cell research, which provides the possibility of bone marrow stem cells to be used for non-hematopoietic system diseases. There are rich data on bone marrow stem cells,which greatly accelerates the research on bone marrow stem cells plasticity. This article reviews the hot topics on plasticity of bone marrow stem cells.

Objective:To explore the constitution characteristics in patients with vascular dementia(VaD),and to analysis the constitutional risk factor in VaD.Methods:This was a case-case control study.66 VaD patients and 51 stroke patients were selected by MMSE and Similarities test in WAIS-R、Blessed Behavior Scale.The diagnosis of VaD based on the DSM-Ⅳ and the NINDS-AIREN criteria、Hachinski Ischemia Scale、Cornell Scale of Depression in Dementia and the Clinical Dementia Rating.The stroke group was of MMSE≥28.The structured questionnaire of constitution was used to investigate and Wang Qi's method was used to constitution diagnose.Results: Yin Deficiency was the most common type in the VaD group and the stroke group(31.8% vs 45.1%),and the second was Phlegm-Damp(30.3% vs 35.3%).The frequencies of Yang Deficiency(15.2% vs 2%,P

Objective To observe clinical efrect of treating angina pectoris with Shuxuening injection combined with western medicine.Methods 62 cases patients with angina pectoris were randomly recurited into a control group and a treatment group,The control group was treated with western medicine,and the treatment group was treated with Shuxuening injection based on the control group.The clinical effect was observed between the two groups.Results The clinical effect in the treatment group(83.9%)was significantly higher as compared to the control group(64.5%)(χ~2=2.352,P＜0.05).Conclusion The treatment of Shuxuening injection combined with western medicine on angina pectods is better than westem medicine only.
