BACKGROUND： Some scholars think that hypertension is the major risk factor to cause Binswanger disease （BD）, however, BD is also found in some persons with normal blood pressure, so we presume that some other factors, such as diabetes mellitus, hyperlipemia, coronary heart disease and transient ischemic attacks and so on, might participant in the onset of BD. OBJECTIVE： To comparatively observe the difference in accompanying diseases, transcranial doppler （TCD） performance, blood glucose and blood lipid level between BD patients and healthy subjects who received health examination, and between BD patients with different disease condition. DESIGN ： Case-control analysis SETTING ： Department of Emergency, Qingdao Municipal Hospita PARTICIPANTS： Totally 126 patients with BD, 65 male and 61 female, aged from 67 to 85 years old, who hospitalized in the Medical School Hospital of Qingdao University and Qingdao Municipal People＇s Hospital, were chosen, serving as BD patients group. All the patients met the clinical diagnostic criteria of BD introduced by Bennett et al. Another 126 persons, 65 male and 61 female, aged ranging from 67 to 80 years, who received health examination in the same hospital, were homeochronously chosen, serving as control group. Informed consents were obtained from all the subjects. METHODS ： After being admitted, all the subjects including BD patients and persons who homeochrenously received health examination in the same hospital were given examinations of blood pressure, blood lipid, blood glucose, electrocardiogram （ECG） and TCD. Fifty-seven patients with BD were in the stable period and 69 in the progressive period （Stable period： no local or subcortical function disorder found, and no changes in the range of white matter lesion showed by CT and/or MRI in recent 3 months; Progressive period： with local or subcortical function disorder and increase in the range of white matter lesion showed by CT and/or MRI in recent 3 months）.

The fractional order derivative was introduced to the seepage flow research to establish the relaxation models of non-Newtonian viscoelastic fluids in dual porous media. The flow characteristics of non-Newtonian viscoelastic fluids through a dual porous medium were studied by using the Hankel transform, the discrete Laplace transform of sequential fractional derivatives and the generalized Mittag-Leffler function. Exact solutions were obtained for arbitrary fractional order derivative. The long-time and short-time asymptotic solutions for an infinite formation were also resulted. The pressure transient behavior of non-Newtonian viscoelastic fluids flow through an infinite dual porous media was studied by using Stehfest＇s inversion method of the numerical Laplace transform. It shows that the characteristics of the fluid flow are appreciably affected by the order of the fractional derivative.

For two integers l ：〉 0 and k ≥ 0, define C（l, k） to be the family of 2-edge connected graphs such that a graph G ∈ C（l, k） if and only if for every bond S lohtain in E（G） with ｜S｜ ≤3, each component of G - S has order at least （｜V（G）｜ - k）/l. In this note we prove that if a 3- edge-connected simple graph G is in C（10, 3）, then G is supereulerian if and only if G cannot be contracted to the Petersen graph. Our result extends an earlier result in [Supereulerian graphs and Petersen graph. JCMCC 1991, 9： 79-89] by Chen.

Objective To study the effect of salicylate on the expression and function of NMDA receptors in spiral ganglion neurons （SGNs）. Methods The mRNA of NR1 subunit of NMDA receptor in modiolus tissues were detected by Real time fluorescence quantitative PCR （FQ-PCR）. NMDA receptor whole-cell currents were recorded using patch clamp in acute isolated SGNs. Results Compared with the control group, salicylate significantly increased the mRNA level of NR1 subunit in SGNs. NMDA of concentrations ranging from 0.1 mM to 10 mM evoked no current in SGNs. NMDA （0. 1mM and 0.5 mM） applied with salicylate （5 mM）, however, induced inward currents （212.6±15.2pA, n=5; 607.9±44.3pA, n=5） in a dose-dependent manner, which could be inhibited by APV. Salicylate alone did not produce any current in SGNs. Conclusion Salicylate increases the expression of NMDA receptors and facilitates the currents mediated by NMDA receptors in SGNs.

The description of line-line topological relations is still an unsolved issue although much effort has been done. The problem is involved in many practical applications such as spatial query, spatial analysis and cartographic generalization. To develop a sound and effective approach to describe line-line relations, it is first necessary to define the topology of an individual line, i.e., local topology. The concept of connective degree is used for the identification of topological differences in the geometric structure of a line. The general topological definition of a line is given, i.e., endpoints set and interior point set. This definition can be applied to the embedded spaces of different dimensions, whether co-dimension is equal to or larger than zero. On this basis, a generic model called the 4 intersection-and-difference is set up for the description of basic line-line topological relations, upon which a conceptual neighborhood graph is built with consideration of topological distance, it is concluded that the proposed model can represent the property of topological changes, and basic relations between line segments in IR^1 and IR^2.

Background Diabetes has been associated with increased risk of fracture and impaired fracture healing. The aim of this study was to examine the influence of diabetes on perioperative complications, length of stay and ambulatory ability recovery in individuals with hip fracture, and to determine whether changes could be made to improve treatment outcome. Methods The study included 707 hip fracture patients treated at Beijing Jishuitan Hospital between July 2009 and December 2010. The medical history and perioperative complications were compared between non-diabetic and diabetic groups. Length of stay, days awaiting surgery, and days of hospitalization after surgery were also analyzed. Ambulatory ability was compared at 1-year follow-up using the Chi-square test and Fisher＇s exact test. An independent Student＇s t-test was used to compare normally distributed continuous data. Results Patients with diabetes were more likely than non-diabetic patients to develop cardiac perioperative complications （8.9% vs. 3.0%, P=0.021）, urinary tract infections （12.0% vs. 2.8%, P 〈0.001）, and gastrointestinal symptoms （15.0% vs. 6.8%, P=0.003）. No difference in perioperative complications was observed between the groups. Days awaiting surgery and length of hospital stay were both longer in the diabetic group （（8.0＋5.1） vs. （6.2＋3.7） days and （16.5＋3.8） vs. （13.3＋3.8） days, P 〈0.001, respectively）. Before the occurrence of fracture, patients with diabetes were less likely to be ambulatory outdoors （71.9% vs. 85.9%, P 〈0.001） and had more restricted walking ability. After at least 1-year follow-up, similar proportions of patients in the non-diabetic and diabetic groups （16.1% and 15.9%, respectively）, who were able to ambulate outdoors before the fracture, became housebound till the final follow-up. Conclusions Diabetics are at increased risk of specific complications and have a longer time to surgery and longer in-hospital stay, but generally have similar recovery to non-diabetics ther
