Objective To evaluate the efleet of continuous subcutaneous insulin infusion (CSII)combined with mefformin hydroehloride( Met H)on type 2 diabetic patients. Methods 240 patients with type 2 diabetes melli-tus (T2DM) were divided into 3 groups randomly: CSII combined with Met H ( A group: n=80) ; simple CSII ( B group:n=80) ; multiple deliver insulin (MDI) ( C group: n=80). The levels of blood glucose, HbA1 e, therapeutic time, a-mount of insulin, Fins ,C-P, HOMA-IR and IAI were compared among them before and after 10d of treatment. Results GroupA, B eornpared with group C, the levels of HbA1 e significantly deeroased in other two groups [ ( 8.0±3.2)%vs. (6.9±1.4)% and(7.0±1.2)% ] (aU P<0.05),so did the therapeutic time[(6.0±1.9)d vs. (3.0±1.4) and(3.5±1.5) d] and insulin dose[ (55.0±17.0) U/d vs. (38.0±15.0) U/d and(45.0±16) U/d] (all P<0.05). The insulin dose was much less in group A than in group B. Versus group B and C,the HOMA-IR of group A (0.8±0.3 vs. 1.5±0.4 and 1.6±0.4)decreased(P<0.05) ,and IAI(-2.0±4.3 vs. -3.6±4. 2 and -4.1±4.3) increased (all P<0.05), without the function impairments of heart, liver or kidney. Conclusion CSII in combi-nation with mefformin hydreehloride can significantly enhance the treatment effect of the patients with type 2 diabetes mellitns; reduce blood glucose and HbA1 e, improve insulin resistenee,lessen insulin need.

Objective To observe and measure the Doppler sonographic features of benign and malignant ovarian neoplasms,which included morphology and hemodynamics of tumor angiogenesis,and to select the most significant features. Methods Ninety-five patients with one hundred and five ovarian tumors were examined preoperatively by power Doppler sonography to observe the morphology of tumor angiogenesis. The hemodynamic features of tumor angiogenesis referred for pulsed Doppler sonography evaluation were measured,which included peak systolic velocity(V PS ),end diastolic velocity(V ED ),mean flow velocity(V M),pulsatility index(PI),resistance index(RI) and diastolic notch. To assess the variables jointly,stepwise regression analysis was used to identify the group of features that allowed the best prediction of benignity versus malignancy. Results All Doppler features significantly associated with malignancy .The ROC curve of RI revealed that the cutoff of RI( 0.51 ) with the highest accuracy had a sensitivity of 98.0 % and specificity of 96.2 %.Conclusions RI was most significantly associated with malignancy. The combination of RI and gray-scale sonography can maximize the ability to discriminate between benign and malignant ovarian tumors.

Objective To evaluate color Doppler sonography in the diagnosis of local recurrence in patients undergoing Miles procedure for rectal carcinoma.[WT5”HZ] Methods Transperineal and transsacral color Doppler blood flow sonography was performed on 51 patients presenting presacral masses after Miles procedure for rectal carcinoma. Blood flow richness and the blood flow dynamics indexes e.g. peak systolic velocity (PSV), diastolic velocity (EDV),resistive index (RI), and pulsatility indexs (PI) were recorded and analyzed. Results Blood flow signals in the recurrent masses were mainly Ⅱ-Ⅲ amounting to 81 82% (27/33), and that of benign masses were mainly 0-Ⅰ,Ⅱ-Ⅲ amounting to 27 78% (5/18). Both were significantly different (? 2=14 55, P

Objective:To investigate the effect of DKK1 on linearly patterned programmed cell necrosis (LPPCN) and vasculogenic mim-icry (VM) and the related molecular mechanism in non-small cell lung cancer (NSCLC). Methods:A total of 173 human NSCLC speci-mens were collected to detect LPPCN by H&E staining, detect VM with CD31/PAS double staining, and investigate DKK1 and related protein expression by immunohistochemistry. The clinical pathological significance of LPPCN, VM, and DKK1 and the correlation of them were analyzed. Human NSCLC H460-DKK1 cells were engrafed in nude mice to evaluate the influence of DKK1 up-regulation on VM and LPPCN in vivo. Results:Approximately, 14.45%(25/173) of NSCLC had VM and 49.71%(86/173) had LPPCN. 25.6%(22/86) of NSCLC cases in LPPCN-positive group formed VM. Both of VM and LPPCN were all correlated with poor differentiation, late TNM stage, easy recurrence and metastasis and poor prognosis in NSCLC. DKK1 expression in the VM-positive group and the LPPCN-positive group was higher than that in the VM-negative group and the LPPCN-negative group, respectively. DKK1, LPPCN, and VM were positive-ly correlated with VE-cadherin, MMP-2,β-catenin nuclear expression and Twist1. H460-DKK1 transplantation tumor model confirmed that DKK1 promotes the expression of VM and LPPCN and related proteins in NSCLC. Conclusion:The increase of theβ-catenin and Twist1 expression induced by DKK1 may promote the formation of LPPCN and VM in NSCLC.

Objective To establish and identify the induced pluripotent stem cell(iPSC) line reprogrammed from human umbilical cord mesenchymal cells(HuMSCs).Methods HuMSCs were cultured by adhesion method,and OCT4,SOX2,KLF4,c-Myc,NANOG,LIN-28 were transfected into HuMSCs with lentiviral victor to reprogramme HuMSCs into iPSC.Morphological observation,pluripotency genes (SOX2,TDGF1,THY-1,OCT4,REX1 and TERF1) expression,alkaline phosphatase detection,karyotype analysis,embryonic stem cells (ESC) specific proteins (NANOG,OCT4,SSEA-4,TRA-1-81) immunofluorescence staining,differentiated into teratomas in vivo(inject the iPSC into SCID mice) and embryniod bodies in vitro were performed to exam the pluripotency of the iPSC.Results Four days after being infected by lentivirus,the HuMSCs became round-shape; 10 days after infection,some embryonic stem(ESC)-like colonies appeared.Fourteen days after infection,picked up the regularly shaped colonies and cultured several passages.About 1.25％ HuMSCs were reprogrammed into iPSC.The iPSC presented clone-like growth like ESC.All the cells were positive to alkaline phosphatase staining and expressed the pluripotency genes.The iPSC also expressed the ESC specific proteins,and karyotype analysis showed normal chromosome caryotype (46,XY).Furthermore,the iPSC could form embryoid bodies in vitro,expressed alpha fetoprotein(AFP),smooth muscle actin(SMA) and β-tubulin.The iPSC could alsoform teratomas in vivo.Conclusion OCT4,SOX2,KLF4,c-Myc,NANOG,LIN-28 can reprogram HuMSCs into iPSC efficiently.
