Vildagliptin,a dipeptidyl peptidase-4 (DPP-4) inhibitor,is always used in combination with metformin.Data from multiple clinical trials showed that vildagliptin and metformin combination therapy can improve HbA1c,fasting blood glucose,and postprandial blood glucose without weight gain,good gastrointestinal (GI)tolerance,and no increase in the incidence of hypoglycemia.Vildagliptin increases plasma levels of glucagon-like peptide-1 ( GLP-1 ).When glucose levels are above normal fasting levels,enhanced GLP-1 levels stimulate insulin secretion.Mefformin has been shown to increase insulin sensitivity and inhibit hepatic glucose production.The effect of vildagliptin to increase plasma levels of intact GLP-1 was enhanced in patients receiving concomitant metformin.

Objective To explore the effects of various location methods on the successful rate of placement nails by the entrance spot of lumbar vertebra pedicle. Methods The clinical data of 105 patients with 462 times of internal nail fixation of lumbar vertebra pedicle were analyzed, and the successful rates of placement nails one time were compared among 5 location methods. Results 462 times of internal nail fixation of lumbar vertebral pedicle were performed safely. Postoperative X-ray imagining showed that 322 nails were located in the middle of pedicle of lumbar vertebra, 58 nails in its inferior part, and 82 nails in its superior part. The successful rate of placement nails one time by the location method of four quadrants technique was 86.9%, which was significantly different compared with the other 4 location methods(P

Objective To assess the effect and safety of applying Diver CE thrombus-aspirating device during direct percutaneous coronary intervention(PCI)in pations with ST-segment elevation myocardial infarction(STEMI). Methods Select 46 patients with STEMI who underwent direct PCI between July,2006 and June,2007 in Fushun Central Hospital. Dividing these patients into thrombus-aspirating group and direct PCI group,comparing the difference in chest pain relieving.magnitude of ST-segment declining in 2h,TIMI flow grade 3,the maximum value of CK and CK-MB,EF and MACE outcome(death、myocardial infarction and targert vessel revascularization).Results The percent of chest pain relieving、magnitude of ST-segment declining 、TIMI flow grade 3、the maximum value of CK and CK-MB,and EF in thrombus-aspirating group are piror to the direct PCI group(P0.05).Conclusion applying Diver CE thrombus-aspirating device during PCI can obviously reduce thrombus in coronaty artery and distal embolization,improve myocardial reperfusion more effectively.

A 27-peptide,a fragment of hepatitis delta antigen(HDAg),was synthesized and used to develop an ELISA method for ihe detection of anti-HD.It was found that positive anti-HD reaction occurred between the coated 27-peptide and a stored sample of serum which was known anti-HD positive.Absorption test revealed that the synthetic peptide competed with natural HDAg for anti-HD,suggesting that the peptide possessed the antigenicity similar to that of natural HDAg.The antigenicity of the synthetic peptide was quite specific wihtout cross reaction with normal human and mouse sera and with anti-HA.anti-HB and anti-HC sera.Among 300 blood donors,there was only 1 case(0.33%)anti-HD positive with an ALT level 2 times higher than normal.In 41 cases of non-B hepatitis and 52 cases of HAV hepatitis,none was anti-HD positive.In 211 cases of various types of HBV hepatitis,21 were(9.95%)anti-HD positive,among whom 2/82(2.5%)werehealthy HBV carriers,6/43(13.95%)were patients with a-cute icteric hepatitis,6/60(10.00%)were patients of chronic active hepatitis,4/18(22.20%)were patients of severe hepatitis,and 3/8(37.50%)were those with liver cirrhosis.These results were consistent with those in our previous reports.

Objective To investigate the effect of Icariin ( ICA) experimental IgA nephropathy in rats and to explore related mechanisms .Methods Experimental IgA nephropathy rat model was established and then model rat were treated with or without different doses of ICA .Then, urine RBC, Urine protein and urine NAG were analyzed; IgA precipitation was detected with immunofluorescence staining;the protein level of NF-κBp65 and MCP-1 were examined by immunohistochemical staining;the mRNA level of IL-4, IL-10 and IL-13 were determined by quantitative PCR .Results The concentrations of urine RBC, Urine protein and urine NAG were reduced after ICA treatment , as companied by a decrease of IgA precipitation .Moreover, ICA treatment also decreased the protein level of NF-κBp65 and MCP-1, and the mRNA level of IL-4, IL-10 and IL-13.Conclusions ICA exerts a certain degree of efficacy on the treatment of experimental IgA nephropathy through regulating NF-κBp65 and MCP-1 expression and the immunoregulation mechanism .

time of infusion. Data analysis indicated that A1B3C2 was the best combination of the 3 factors according to the degree of lung injury. Conclusion Adequate amount of HES 200/0.5 infused during compensated stage of hypovolemic shock produces best result.

Objective To investigate the retinal toxicity and verify the safe dose of intravitreal injection of nonsteroid anti inflamatory drug, diclofenac sodium. Methods Twenty eight healthy adult white rabbits were divided at random into 7 groups and received in every right eye the intravitreal injection of a single dose of diclofenac sodium solution ranging from 0.4～1.0 mg/0.1ml respectively,the left eyes were regarded as control ones. Before injection and on the 1st, 3rd, 7th, 14th, 21st, and 28th day after injection the electroretinography on both eyes was examined. On the 28th day after injection the retinas of two rabbits of every group were examined by using light microscopy. On the 10th and 30th day after injection the retinal tissues around the optic nerve disk of two eyes from every group at random were tested by using transmission electron microscopy. Results The ratio of amplitude of b wave of electroretinography in 0.4 mg and 0 5 mg groups had no significant difference from groups before injection,the retinal tissues showed no structural changes in light and electron microscopy examination. The ratio of amplitude of b wave of photoptic electroretinography in 0.6 mg groups in the early stage after injection was markedly reduced ( P
