Objective To study the relationship between serum homocysteine level and acute type 2 diabetes mellitus complicated with cerebral infarction.Methods Patients were divided into three groups:acute diabetic cerebral infarction group including 87 patients,diabetes mellitus including 72 patients and control group including 67 healthy persons.The HCY,folic acid,VitB12 and serum lipid were determined.The data was analyzed and the relationship was discussed.Results The level of HCY in diabetic cerebral infarction group[(15.7 ±9.7)nmol/L]was much higher than that in the other two groups[(11.9±7.2)nmol/L and(13.5±6.1)nmol/L].Conclusion HCY maybe participate in occurrence and development of diabetes and pathological changes of blood vessels.It was an independent risk factor of acute cerebral infarction.

Objective A Halotherapy (HT) device for meeting the demands of human body,has been trial-produced to efficiently treat the respiratory diseases.Method By means of grains of salt having been processed in a series of ways,proper halospray has been made for the treatment of respiratory diseases.Result Y JM-1 desk-top Halotherapy device,meeting the demands of human body and featuring a good halospray size and space density,has been developed,which is highly efficient to the treatment of respiratory diseases.Conclusion Y JM-1 desk-top Halotherapy device is a novel and creative one for the treatment of respiratory diseases.

Objective To study and observe the changes of pancreatic blood flow and blood miR indexes of patients with pancreatic cancer.Methods 70 patients with pancreatic cancer were selected as the observation group,70 health persons of the same age at the same period were selected as the control group, then the blood flow indexes and blood miR of observation group’s lesion and tumor adjacent tissue and control group’s healthy pancreas were detected,and the detection results of control group and observation group were compared,then the above indexes of observation group with different Hemrick stages were compared.Results The lesion blood flow indexes of observation group were all obviously worse than those of control group(P<0.05),blood miR indexes were all higher than those of control group(P <0.05),the lesion and tumor adjacent tissue blood flow indexes all had obvious differences(P<0.05),and the above indexes of observation group with different Hemrick stages all had significant differences(P<0.05).Conclusion The pancreatic blood flow and blood miR of patients with pancreatic cancer all show obvious abnormal state,and the differences of indexes of patients with different Hemrick stages are all prominent, so the pancreatic blood flow and blood miR indexes all have higher value for the patients with pancreatic cancer.

Objective To determine the reversal effect of psoralen on multidrug resistance (MDR) in the harringtonine (HT)-resistant leukemic cell line HL60/HT. Method The modulating effect of psoralen on MDR in HL60 and HL60/HT cells were determined by the measurement of cell growth and viability via MTT assay. High performance liquid chromatography(HPLC) was used to analyze intracellular HT concentrations in HL60/HT and HL60 cells treated with psoralen. Result Psoralen from 1 to 20 ?mol/L could reduce the value of IC_ 50 to HT and enhance the accumulation of HT in HL60/HT cells. Conclusion Psoralen can reverse MDR of HL60/HT cells and is a potential modulator of MDR.

Objective To discuss the possibility and efficiency by using Six Sigma method.Methods By using"five steps" of Six Sigma,management of medical consumable materials storehouse was improved continuously.Such Sigma levels before and after the implementation in 6 months were compared as satisfaction for medical service,supply punctuality,rate of high-quality products,and the realization of"Zero Storage".Results All Sigma levels were raised.Conclusion The method of Six Sigma fits for the storehouse management of medical materials and can improve the management quality.

Various conditions were compared for extracting the proteolytic enxyme from the alimentary canal of Pneumatophorus juponicus (Houttuyn). The results showed that when using CaCl2 as activator, the suitable conditions were pH7. 5,extracting temperature 20 C,extracting time 2h,activiting time 16h,70% alcohol precipitaion.

Objective To optimize the solid-phase extraction method by comparison of the extraction recovery of docetaxel plas-ma samples.Methods After extracted by different solid-phase cartridges with water,acetonitrile,and different content methanol e-lution,the plasma samples were analyzed on an Phenomenex LUNA C18 column(4.6 mm×250 mm,5μm)with mehhanol:acetoni-trile:water(42∶26∶32,v/v/v)as the mobile phase.From the recovery achieved,the best solid phase cartridge was found.Results This method consists of using 60%-80% methanol for the elution.Among the three kinds of solid-phase being tested,Waters Oasis HLB cartridge was found to be the best one.Conclusion The average extraction recovery of the Waters Oasis HLB cartrid-ges was between 95%-105%,and it can be used in the analysis of docetaxel in plasma samples.
