Objective To investigate the optimal index of serum lipids to predict insulin resistance(IR) in subjects with normal fasting plasma glucose(FPG).Methods In Nor 2003-11 the 1002 subjects with FPG

Nine hundred and two subjects were divided into combined hyperlipidemia group, hypertriglyceridemia group, hypercholesteremia group, isolated low high-density-lipoprotein group and normal group. The results suggested that insulin resistance may be accompanied with hyperlipidemia and hypertrigly-ceridemia.

Relationship between blood pressure and insulin resistance was analyzed in 839 non hypertensive subjects (fasting plasma glucose

Objective To discuss the intervention effect of cognition therapy for perioperative patients of digestive tract with depression and/or anxiety symptoms.Methods 135 patients with digestive tract operation were randomly divided into intervention group and non-intervention group.The patients in intervention group accepted cognition therapy.The Mores of SDS and SAS,the curative effect and hospitalized time were compared among the two groups and the norlns of our country at last.Results (1)The scores of SDS and SAS in the two group patients in pre-operation were no difference(P＞0.05),but all were significantly higher than those of the norms of our country(P＜0.01).It indicated that patients have evident depression and/or anxiety symptoms pre-operation. (2)Compared with pre-operation,the scores of SDS and SAS in the intervention group patients showed significantly lower after operation(P＜0.01),which returned to the norms of our country(P＞0.05),and showed lower than those of the non-intervention group predominantly (P＜0.01).This indicated that cognition therapy can relieve the depression and/or anxiety symptoms of the perioperative patients.(3)Though the therapeutic effect of the two group are similar(P＞0.05),but the hospitalized fime decurated in the intervention group predominantly(P＜0.01).Conclusion The periopexative patients of digestive tract had obvious depression and/or anxiety symptoms.Cognition therapy could relieve the depression and/or anxiety sympmms of the perioperative patients,this was helpful for patients to recover early.

OBJECTIVETo investigate the effects of angiotensin II (Ang II) antagonist telmisartan on retina vessel endothelial cell apoptosis and its impact on the ACE2-Ang-(1-7)-Mas axis in spontaneous hypertensive rats (SHR).

METHODSThirty-six SHR 16 week-old were randomly divided into 3 groups (n = 12 each): SHR, SHRT (telmisartan 10 mg · kg-1 · d-1 by gastric gavage) and SHRTA group (telmisartan 10 mg · kg-1 · d-1 by gastric gavage plus intravenous injection of A-779 0.5 mg · kg-1 · d-1), twelve WKY rats served as normotensive control group. Systolic blood pressure was measured at pre-treatment and 8 weeks later. After 8 weeks, rats were sacrificed, the expression of ACE2 and Mas in retina were analyzed by qRT-PCR, Western blot and Immunohistochemistry, the Ang-(1-7) concentration in serum was measured by ELISA. Specimens were obtained and stained by hematoxylin and eosin, and the morphology of retina vessel was observed. Apoptosis of vessel endothelial cells were determined by using terminal deoxynucleotidyl transferase mediated dUTP nick end labeling method.

RESULTSThe systolic blood pressure of SHR, SHRT and SHRTA groups at baseline were significantly higher than age-matched WKY group (all P < 0.01). Eight weeks later, the systolic blood pressure group was significantly lower in SHRT group than in the SHR group (P < 0.01), this effect was partly reversed in SHRTA group. The retinal ACE2 mRNA and protein expression was significantly lower in SHR group than in WKY and SHRT groups (P < 0.01), which was similar between SHRT group and SHRTA group (P > 0.05). The retinal Mas mRNA and protein expression were significantly lower in SHR group compared to WKY and SHRT groups (all P < 0.01), which was significantly lower in SHRTA group than in the SHRT group (P < 0.05). ELISA results showed that serum Ang-(1-7) protein level was significantly lower in SHR group than in WKY group and SHRT group (both P < 0.05), which was lower in SHRTA group compared to SHRT group. Retinal vessel endothelial cell apoptosis was higher in SHR group than in WKY group, which could be reduced by cotreatment with telmisartan and this beneficial effect could be reversed by A-779.

CONCLUSIONTelmisartan can reduce retinal vessel endothelial cell apoptosis via upregulating the ACE2-Ang-(1-7)-Mas axis.

Purpose/Significance To construct the ontology model of breast cancer knowledge graph,and to realize the structured expres-sion and visual display of breast cancer knowledge.Method/Processs Breast cancer knowledge is extracted and represented,and the ontology model of breast cancer knowledge graph is constructed by Protégé software.The model includes 5 types of entities including patient,basic infor-mation of patient,inspection,diagnosis and attribute value of inspection,and more than 10 kinds of relationships such as having,examining,diagnosing,belonging and so on.Result/Conclusion The graphical display of breast cancer knowledge helps to improve the public's attention and understanding of breast cancer,and has a positive effect on the prevention and health management of breast cancer.

Hemorrhagic transformation (HT) is a serious complication after acute ischemic stroke, leading to increased adverse outcomes and mortality. In recent years, there has been an increasing number of studies in predicting HT occurrence, but most of the existing studies have focused on patients accepted reperfusion therapy, and few studies have predicted spontaneous HT. This article provides a review of epidemiology, risk factors, and available prediction models for prediction of spontaneous HT after acute ischemic stroke.

Human motion control system has a high degree of nonlinear characteristics. Through quantitative evaluation of the nonlinear coupling strength between surface electromyogram (sEMG) signals, we can get the functional state of the muscles related to the movement, and then explore the mechanism of human motion control. In this paper, wavelet packet decomposition and : coherence analysis are combined to construct an intermuscular cross-frequency coupling analysis model based on wavelet packet- : coherence. In the elbow flexion and extension state with 30% maximum voluntary contraction force (MVC), sEMG signals of 20 healthy adults were collected. Firstly, the subband components were obtained based on wavelet packet decomposition, and then the : coherence of subband signals was calculated to analyze the coupling characteristics between muscles. The results show that the linear coupling strength (frequency ratio 1:1) of the cooperative and antagonistic pairs is higher than that of the nonlinear coupling (frequency ratio 1:2, 2:1 and 1:3, 3:1) under the elbow flexion motion of 30% MVC; the coupling strength decreases with the increase of frequency ratio for the intermuscular nonlinear coupling, and there is no significant difference between the frequency ratio : and : . The intermuscular coupling in beta and gamma bands is mainly reflected in the linear coupling (1:1), nonlinear coupling of low frequency ratio (1:2, 2:1) between synergetic pair and the linear coupling between antagonistic pairs. The results show that the wavelet packet- : coherence method can qualitatively describe the nonlinear coupling strength between muscles, which provides a theoretical reference for further revealing the mechanism of human motion control and the rehabilitation evaluation of patients with motor dysfunction.
