Objective To investigate the association of insulin dose with clinical factors of type 2 diabetes. Methods We reviewed the data of 214 type 2 diabetic patients who received insulin regimens.We compared the insulin dose and period at the targeted blood glucose levels among 6 groups according to different type of oral hypoglycemic agents. Results There existed statistically significant correlations of the glucose-targeted insulin dose with course,FPG,BMI,combination therapy with oral hypoglycemic agent(P<0.1,test level P=0.1).Merely metformin failure group took less insulin than the group admitted due to combination therapy failure (P=0.016, 0.53(0.35~0.62)U/kg and 0.63(0.51~0.75)U/kg respectively).The longest targeted period existed in the later. Relationship between the targeted bedtime insulin NPH dose and FPG level can be demonstrated by equation Y=0.255X+7.8. Conclusions The targeted insulin dose is influenced by synthetic factors. Patients admitted due to combination oral hypoglycemic drug failure have the maximal targeted insulin dose and the longest titration period. The final bedtime insulinNPH dose can be predicted by FPG level.

0.05). Significant difference in diffused carbon monoxide percentage and change of heart rates before and after stair climbing test was found in LPF group (P0.05).Conclusions Patients of lung cancer intolerable for lobectomy by static pulmonary function test can be screened by stair climbing test before surgical operation,which can make some of them regain opportunity of surgical operation.

AIM To study the effect of arsenic trioxide(As 2O 3) on inhibition of proliferation human melanoma A 375 cells METHODS The cell proliferation inhibition was measured by MTT colorimetric assay; The expressions of nm23 was determined by immunohistochemistry.RESULTS As 2O 3 could result in the concentration dependent inhibition of A 375 cells proliferation. The volume of IC 50 was 13.05 ?mol?L -1 . The expression of nm23 anti transfergene in A 375 cells could be induced by As 2O 3 (2 ?mol?L -1 ). CONCLUSION As 2O 3 can inhibit proliferation and induce anti transfer protein of A 375 cells.

Objective To obtain highly purified oligodendrocyte precursor lineage cells in vitro and make identification.Methods The oligodendrocyte precursors were separated from astrocyte by orbital shaker and further purified by differential adhesion,and finally cultured in chemically defined serum-free medium,with appended neurotrophin 2(N2),platelet-derived growth factor(PDGF),basic fibroblast growth factor(bFGF).Immunofluorescence assay was applied to identify the separated cells with A2B5,O4,O1 and glial fibrillary acidic protein(GFAP) antibodies.Results Over 95% of cultured oligodendrocyte precursor cells were obtained.The oligodendrocyte progenitors were A2B5 and O4 positive,immature oligodendrocytes were O4 and O1 positive while GFAP were negative.Conclusions Separation and purification by shaking and differential adhesion and chemically defined medium are suitable and effective to obtain highly purified oligodendrocyte precursor cells.Cell output will increase notabily and rest in immature phase by appending both N2,PDGF and bFGF.

Corneal endothelial cell(CEC)is the most critical part for the cornea, of which activity can influence the postoperative vision.It is very important for the clinical cornea preservation considering the function and its self-purification of donor cornea.There are a variety of classical methods, which can significantly prolong the saving time of donor cornea with its good quality of CEC.We reviewed the published papers about present preservation methods of cornea, which can give us many suggestions for the clinical cornea preservation.

Objective To evaluate the value of endorectal ultrasound(ERUS)combined with real-time elastography in the staging of advanced rectal cancer in elderly patients.Methods A total of 50 patients with advanced rectal cancer underwent endorectal ultrasound and real-time tissue elastography imaging at our hospital from Jun.2014 to Oct.2015.Their staging results were compared with postoperative pathology.Results The accuracy,sensitivity and specificity of ERUS in the staging of advanced rectal cancer(T3)were 90% (45/50),93.5% (43/46)and 50% (2/4),respectively.The accuracy,sensitivity and specificity of real-time elastography in the staging of advanced rectal cancer(T3)were 84%(42/50),89.1%(41/46)and 25%(1/4),respectively.With the combination of the two techniques,the accuracy,sensitivity and specificity in the staging of advanced recta[cancer(T3)were 96% (48/50),97.8% (45/46)and 75% (3/4),respectively.There was no significant difference in accuracy and sensitivity(x2 =4.000 and 3.100,P=0.373 and 0.542)between the three approaches.Kappa values between each of the three approaches and surgical pathology were 0.531,0.252 and 0.728,respectively.Conclusions Real-time tissue elastography in the diagnosis and staging of advanced rectal cancer can be enhanced when used in combination with endorectal ultrasound.

Objective:To explore the resource of rice bran by comparing antioxidative activities and growth promotion of Bacillus bifidus between supernatant of formented rice bran(RBF) by Bacillus natto and water extract of rice bran(RBW) . Method:The reducing capacity the?OH and ??O 2 scavenging capacity and the inhibitory effect to oxidize lard were determined in vitro. The growth promotion for Bacillus bifidus by photodensity with simulated condition was investigated in vivo. Results:RBF and RBW had antioxidant activity in vitro. The IC50 of scavenging?OH and ??O 250 of RBF was 3.55 mg/ml and 23.5 mg/ml,0.3 and 10 folds higher than that of RBW respectively. In inhibiting oxidation of lard,RBF had a little higher antioxidative activities than RBW,near VE. RBF and RBW could promot growth of Bacillus bifidus by 65.2% and 17.8% respectively. By enzymatic digestion,the promotive rate of RBF was still 51.6%. Conclusion:RBF had higher antioxidant activity and growth promotion to Bacillus bifidus.
