Aim To investigate the effects of EDT on anoxia and ischemic injury in cultured PC12 cells. Methods Cultured PC12 cells were treated with 1 mmol?L -1 Na 2S 2O 4 and 20 mmol?L -1 NaCN in combination with glucose deprivation. The protective effects of EDT on these two models were evaluated by lactate dehydrogenate (LDH) efflux assay and colormetric MTT assay.ResultsEDT, within the range of 10 -8～ 10 -6 mol?L -1, significantly antagonized LDH efflux induced by two models and increased the optical density at 570 nm tested by colorimetric MTT assay in concentration-dependent manner. 10 -6 mol?L -1 EDT might time-dependently inhibit two injuries and reach maximal level at 48 h. Conclusion EDT can protect PC12 cells from anoxia and ischemic injury.

Objective To study the situation of pathogenic bacteria of neonate infection in hospital,so can guide clinical doctors use antibiotic rationally. Method The secretions of 159 neonates′ umbilous and eye matter orders were collected to be used as the specimen and the drug susceptibility experiment was done using MIC and K-B methods together in 159 neonates with hospital infection.Results One hundred and eighty-nine pathogenic bacterias were isolated from 1613 specimens.According to our materials,staphylococci aureus was the most important pathogenic bacteria,then staphylococci heamolyticus,staphylococci epidermidis,encherichia coli ,enterobater cloucac ,klebsiella pneumoniae.MRSA- positive rate was 52.6%,ESBLs-positive in E coli was 21%,inklebsiella pneumoniae was 20%.Drugs of sensitivity for Gram positive coccus were vancomycin(0) clindamycin(8.5%) cipnofloxacin(12.2%);the drugs of sensitivity for Gram negative ord were imipenem (4.4%),cipnofloxacin(5.3%),amikacin(12.7%).Conclusion It is instructive that use antibiotic rationally for controlling neonate infection in hospital.

Objective To explore the relationship between serum advanced glycation end products(AGEs) levels in gestation diabetic mother(GDM) and cardiovascular function of newborn infants.Methods Sixty mid-gestation GDM and 72 late-gestation GDM fulfilling the inclusion criteria were recruited,72 mid-gestation and 80 late-gestation mothers with no pregnancy complications were collected as controls.Fasting blood glucose and serum AGEs levels were analyzed in each group.Clinical data of GDM and their babys were collected.Accor-ding to cardiovascular function of neonates,these neonates were divided into 2 groups:normal neonate group with normal cardiovascular function and anormal neonate group with anormal cardiovascular function.Maternal serum AGEs levels,blood glucose between mid-gestation groups and late-gestation groups were compared.Factors which affected the prevalence of complications of fetal outcome in GDM were analyzed.Results 1.Mid-gestation and late-gestation GDM groups had higher serum AGEs levels and fasting blood glucose compared with those of their respective controls(Pa0.05).3.Abnormal fetal outcome in GDM had significantly higher maternal serum AGEs levels than that in controls with normal fetal outcome(P

Measuring the content of soluble reducing sugar, total sugar, soluble protein, guanosine, alkaloids, and succinic acid of Pinellia ternata tuber were measured by anthrone-sulfuric acid colorimetric method, Coomassie brilliant blue method, RP-HPLC, reverse potentiometric titration, acid dye colorimetry, respectively. The result showed that yellow light could promote the growth and development of P. ternata and increase the content of soluble reducing sugar, total sugar, alkaloids, and succinic acid. Under blue light could promote the content of soluble protein and guanosine. Red and yellow light increased the content of chlorophyll a and chlorophyll b, contrastively blue light reduced the content of chlorophyll a and chlorophyll b. White film through the most uniform spectrum was most conducive to the synthesis of chlorophyll a. As single film, blue film, yellow film were more conducive to the synthesis of chlorophyll a, green film and red film had been relatively beneficial to the synthesis of chlorophyll b. Bulbil formed the largest number and the biggest propagation coefficient of P. ternata under red light showed that it could increase the production of P. ternata under red light.

Objective To evaluate blood flow structure and quantify the variation of the flow within left ventricle,assess the impact of chronic heart failure(CHF) by vector flow mapping(VFM).Methods Twenty-seven patients with chronic heart failure and thirty controls were involved.The flow vector images on the section plane of the flow within the left ventricle were acquired by VFM.Time-flow(T-F) curve and all other peak systolic and diastolic flow curve include normal velocity profile,parallel velocity profile,vector profile,flow profile were analyzed by DSA-RS1 program.Results Ventricular ejection peak S,rapid ventricular filling peak E and atrial systole peak A were relatively lower at basal and middle segments in CHF group than normal control group.Normal velocity profile,velocity profile,flow profile at peak S and E were lower at basal and middle segments in CHF group than normal control group.Conclusions VFM technology could provide quantitative and intuitive information to demonstrate the flow structure of the ventricle and evaluate the cardiac function in patients with CHF.
