Multiple scientific technologies are used in modern 120 emergency command center. This paper introduces the frame of l20 emergency command center and the functions of CTI and 3G technology,and analyzes the practical application and effects of CTI and 3G in modern 120 emergency command center.

Spermatogenesis is a process consisting of spermatogonial proliferation, spermatocytic meiosis, and spermiogenesis, and is also considered to be a process in which heterochromatins gradually aggregate and finally reach a highly condensed formation in the sperm head. Recent studies show that epigenetic regulation plays a key role in spermatogenesis. This review discusses the mechanisms of epigenetic regulation in spermatogenesis in three aspects, DNA methylation, histone modification, and noncoding RNAs. These factors are essential for spermatogenesis, fertilization, and embryogenesis by mutual regulation as well as by gene expression regulation, transposon activation, sex chromosome inactivation, and genome imprinting.

Objective To observe the effect of reteplase on the thromboelastogram tracing of patients experiencing acute is-chemic stroke(AIS).Methods Selected 43 AIS inpatients in the Third People’s Hospital of Liaocheng from October,2013 to August,2015,who received reteplase less than 4.5 hours after the onset of syndrome of AIS.Blood samples were obtained before reteplase administration and at 0.5,1,2 and 4 hours after reteplase administration and measured by thromboelastogra-phy.Results The parameters R,K,Angle and MA of the thromboelastogram had changed after beginning administration of reteplase.The R value at 0.5 h after thrombolysis was significantly higher than that before thrombliysis,however,the R Value at 1h after thrombolysis was the most highest,and the K value.At 0.5 h after thrombolysis was the highest.At 0.5 h after thrombolysis MA and Angle values were the lowest,the differences were statistically significant (P<0.001).Conclu-sion The study suggests that the thromboelastogram is an useful tool for determining changes in the coagulation system of patients receiving reteplase.

Autophagy is the cell biology process in which cytoplasmic components are degraded in lysosomes to maintain cellular homeostasis,it is involved in the pathophysiology of several kidney diseases (podocytopathies,IgA nephropathy,diabetic nephropathy,hereditary kidney disease),but its specific effect is still controversial.Most studies suggest that autophagy plays a protective role in kidney diseases,in the future,it may become a new target for the prevention and treatment of kidney disease.

Random clustering was conducted among a total of 1068 residents aged 18 years or older at a certain Shanghai community.And they completed a questionnaire survey.Logistic data processing and model building were performed.The respondents were willing to go to a community health center for the following reasons:close proximity (88.4％),excellent service attitudes (40.4％) and low drug prices (37.8％).No statistically significant differences existed in terms of first choices of community health service,occupation,monthly income and-walking distance (P ＞ 0.05).However,statistically significant differences existed in education level,age and chronic diseases (P ＜ 0.05).

Non-small cell lung cancer has a poor prognosis. Many patients who were proved to have none lymph node metastasis still relapse after operation. It may be caused by micrometastases which can′t be detected by conventional pathologic technique. Recently immunocytochemistry and moleculer methods are used to detect micrometastases in the peripheral blood, bone marrow or lymph node near the tumor. But the standard and reliable methods need to be developed and the clinical significance of micrometastases need to be discussed.

Thrombin activatable fibrinolysis inhibitor (TAFI), a novel regulator of coagulation and fibrinolysis, was discovered recently. The activated TAFI (TAFIa) makes fibrinolysin lose its action sites with fibrin, and thus exerts its fibrinolytic inhibition and promotes thrombosis. Making a thorough study of TAFI may provide a new option for the treatment of ischemic cerebrovascular disease.

The inhibitory effect of Actinidia chinensis Planch(ACP) juice on the endogenous formation of N-nitroso compounds (NOC) in the subjects from a high-risk area for gastric cancer were observed. Total concentration of volatile N-nitrosamines(VNA)in fasting gastric juice and 24-h urinary excretion of N-nitrosoproline (NPRO) were used as indices of endogenous exposure. After iagestion of 30 ml ACP juice the average total VNA concentration was significantly decreased from 2.08?1.06?g/L to 0.42?0.43?g/L (p

OBJECTIVE:To prepare tongmai oral liquid and study its quality control method.METHODS:The danshen root in tongmai oral liquid was identified by TLC.The content of ferulic acid in the oral liquid was determined by HPLC.RESULTS:Danshen root showed a good specificity in qualitation identification.The linear range of ferulic acid was5.12～71.68?g/ml(r=0.9998).The mean recovery was99.96%(RSD=1.3%).CONCLUSIONS:The preparation technology is practicable and quality control method is reliable.
