OBJECTIVE:To observe the effects of sitagliptin phosphate combine with acarbose on blood glucose,blood lipid and the serum glucose transporter 4(GLUT4)in elderly patients with type 2 diabetes. METHODS:86 elderly patients with type 2 diabetes were randomly divided into control group and observation group,43 cases in each group. All patients received guidance about diet,exercise and living habits,etc.,as well as the care about psychology and medication. Based on it,control group was given Acarbose tablet 50 mg/times,tid,chewing when a meal;observation group was given Acarbose tablet(the same dosage and usage)+ Sitagliptin phosphate tablet 100 mg/times,qd,orally. They were treated for 3 months. Fasting blood glucose(FBG),2 h postprandial blood glucose(2 hPG),glycosylated hemoglobin(HbAlc),body mass index(BMI),fasting insulin(FINs),insulin resistance index(HOMA-IR),islet B-cell function index(HOMA-B),total cholesterol(TC),triglyceride(TG),low-density lipo-protein cholesterol(LDL-C),high-density lipoprotein cholesterol(HDL-C)before and after treatment in 2 groups were compared, the incidence of adverse reactions was recorded. Other 43 healthy people were selected as healthy control group,the differences of serum GLUT4 levels before and after treatment between the 2 groups and healthy control group were respectively compared. RE-SULTS:After treatment,the BMI,FBG,2 hPG,HbAlc,HOMA-IR,FINs,TC,TG and LDL-C level were significantly lower than before,observation group was lower than control group;HOMA-B and HDL-C level were significantly higher than before,ob-servation group was higher than control group,with statistical significance(P<0.05). Before treatment,the serum GLUT4 level in 2 groups were significant lower than healthy control group with satistical significance(P<0.05);after treatment,the serum GLUT4 level in control group there was no significant different than before(P>0.05),while the serum GLUT4 level in observation group was significant higher than before and control group;and the serum GLUT4 level in 2 groups were still significant lower than healthy control group(P<0.05). And there was no significant difference in the incidence of adverse reactions(P>0.05). CON-CLUSIONS:Sitagliptin phosphate combine with acarbose can effectively control patients'blood glucose and lipid levels in the treatment of elderly patients with type 2 diabetes,improve HOMA-B and serum GLUT4 level,and does not increase the incidence of adverse reactions,with good safety.

Traditional teaching plays a major role in pre-clinical genetics teaching,but the PBL teaching mode greatly mobilizes the enthusiasm of students in clinical genetics teaching. However reasonably and scientific combination between traditional teaching and PBL teaching contributes to more positive effect in medical genetics teaching.

[ABSTRACT]OBJECTIVE To summarize the clinical related factors and prognostic influence factors of perioperative pulmonary embolism of head and neck malignant tumor.METHODSFrom 2010-2014, our hospital carried out a total of 2736 cases of head and neck malignant tumor surgical operations, of which, 10 cases were clinically diagnosed as postoperative pulmonary embolism, retrospectively analyzed the process of clinical treatment of the patients of pulmonary embolism with head and neck malignant tumors, and summarized their etiological factors, clinical manifestations, diagnosis and treatment. RESULTS The preoperative period incidence of pulmonary embolism in patients with head and neck malignant tumor was 0.37%(10/2736). Their clinical manifestations were mainly of asthma and breathing difficulty, and 3 cases of asymptomatic hypoxemia. 8 cases of patients showed pulmonary artery and branch filling defects after pulmonary artery angiography (CTA), 7 cases of patients got cured and were discharged from the hospital after comprehensive treatment such as anticoagulation etc; 3 cases of patients died after emergency treatment. 2 cases of patients suffered cavity bleeding, and there was no anticoagulant drug adjustment.CONCLUSIONThe mortality of head and neck cancer patients with perioperative pulmonary embolism is high, and therefore, preventive measures and timely treatments are important to reduce the incidence of pulmonary embolism.

Therapeutic hypothermia (TH), also known as targeted temperature management (TTM), is the intentional reduction of core body temperature to 32-35℃. Mild-to-moderate hypothermia and advanced cooling technology can be used as an effective component of multimodal therapy for ischemic encephalopathy, brain trauma, haemorrhagic stroke, or other forms of severe brain injury and acute neurological injuries to achieve neuroprotection. The events occured after an episode of acute neurological injuries and cerebral ischemia are multiple. And the possible explanation for the neuroprotective benefits of hypothermia therapy is inhibiting metabolic disruption, excitotoxicity, oxidative stress, cell apoptosis signals, inflammatory responses, and promoting neuronal integrity and blood-brain barrier integrity. To know the molecular mechanisms of action of TH, which exerts neuroprotective function, will provide clinicians a better understanding the indications and contraindications of this therapy, and provide a possible theoretical reserves and clinical practice for other therapies when used in conjunction with hypothermia.
