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 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 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.

Objective: To evaluate the clinical effect of auricular sticking therapy in treating vascular headache. Methods: Fifty patients with vascular headache were randomized into two groups, 25 cases in each. The treatment group received auricular sticking therapy with magnetic pearls, and the control group was treated by Flunarizine Hydrochloride, 30 d as a treatment session, and the results were measured after one treatment session. Result: The total effective rate was 92.0% in the treatment group while 60.0% in the control group, and the difference was significant (P<0.01). A marked decrease of blood pressure was detected in the treatment group (P<0.05). The mean velocity in middle cerebral artery and anterior cerebral artery both changed significantly (P<0.01). Conclusion: Auricular sticking therapy can significantly improve the condition of vascular headache, as well as reduce blood pressure and help cerebral blood flow.

Yes-associated protein (YAP) is a multifunctional protein that can interact with different transcription factors to acti-vate gene expression. YAP, as the key transcription protein of Hippo pathway, has made important contribution to the control of the or-gan size, stem cell biology, and tissue-specific stem cell self-renewal. In the Hippo pathway, MST1/2 kinases, together with the adaptor protein SAV, phosphorylate LATS1/2 kinases. YAP is phosphorylated and inhibited by the activated LATS1/2, a key component of the Hippo tumor suppressor pathway. In recent years, numerous studies have shown that the high expression of YAP in the embryonic stem cells, neural stem cells, and hematopoietic stem cells can maintain the cancer stem cell;and YAP has become the marker of cancer stem cells. Meanwhile, more and more studies indicate that the disorder of Hippo-YAP signaling pathway may be associated with cancer stem cells. In this review, we mainly discuss the role of the Hippo pathway in the stem cell biology and its potential implications in tis-sue homeostasis and cancer.

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 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.

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
