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

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.

Gastrointestinal tumor patients are characterized by malnutrition resulting from various elements. So it is necessary to analyze,assess, and treat malnutrition of patients with gastrointestinal tumor. Nutrition support is an indispensable step in tumor therapy.

Objective To investigate the clinical festures and CLCN1 gene mutation screen on a myotonia congenital kindred.Methods The clinical data of 22 patients in the myotonia congenital kindred were analysed. Results There were total 68 people in 5 generations, including 24 patients in 4 generations .Both male and female were suffered. All patientes of this kindred showed myotonia with onset the illness from the infant, and 16 cases accompanied with hypermyotrophy.The levels of creatases and dielectric in serum were normal in all the cases. Spontaneous myotonic electric potential were observed on electromyography( EMG ) in 2 cases.The proband was found in light microscope by biopsy that muscle fibers arranged loosenly , size of them mismatched , transverse striation was unclear and some of them was hyperplasia and hypertrophy. Muscle cells degenerated gently with a few inflammatory cells infiltration. No mutation was found in the whole 23 extrons of CLCN1 gene in the 3 patients.Conclusions This kindred accords with the autosomal dominant heredity form Thomsen's disease. The affected numbers have the typical clinical characteristics. No mutation is found when 23 extrons of CLCN1 gene screened in the patients which indicate the genetic heterogeneity may be exist in this kindred.

Objective To access the changes in blood gases and electrolytes during anaphylactic shock induced by Echinococcus granulosus (EG) in sheep.Methods Fifteen healthy sheep of either sex weighing 31.2 ? 3.5 kg were repeatedly infected with EG for six months. The infected sheep were anesthetized with intramuscular thiopental 20mg?kg-1 and ketamine 15 mg?kg-1. The animals were breathing spontaneously and placed on the left side. ECG (lead Ⅱ) was monitored. Swan-Ganz catheter was placed via right internal jugular vein for hemodynamic monitoring. Anaphylactic shock was induced with antigen prepared from fluid in EG capsules. Blood samples were taken from right internal carotid artery before shock (T0) and 3.5 min (T1 ), 8 min (T2), 15 min (T3), 30 min (T4) and 60 min (T5 ) after shock was induced for determination of blood Na+ , K+ , Hct, Hb, pH, PaO2 , PaGO2 and HCO3-. Shock was confirmed by hypotension (MAP decreased by 30%), tachypnea, dyspnea, agitation and pupil dilation. Results Three sheep did not develop shock and two sheep died of severe shock within 10 min after iv antigen challenge. Blood K+ significantly increased at T1 and T2 after antigen challenge and then gradually returned to baseline value at T5 . PaO2 decreased, PaGO2 increased and pH deceased after challenge. Hct and Hb also increased significantly after challenge. Conclusion There are significant changes in blood gas and electrolytes indicated by hyperkalemia, acidosis and hypoxemia during anaphylactic shock induced by EG.

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.
