Objective To investigate the relationship between the acute phase blood glucose and the severity and prognosis of stroke in patients with stroke. Methods One hundred seventy-three consecutive patients with acute stroke were randomly allocated into either a hyperglycemia group (n =72) or a normal group (n = 101) according to whether their random blood glucose levels were > 7.8 mmol/L or not. The average time from stroke onset to admis-sion was 6.5 ± 5.1 hours. The patients were evaluated by the National Institutes of Health Stroke Scale (NIHSS) and Glasgow Coma Stroke (GCS) scores within 20 minutes after clinical reception, The plasma blood glucose detection and bead CT scan were completed in 40 minutes.The patients with cerebral infarction were classified according to the Oxfordshire Community Stroke Project (OCSP) criteria, and the survivors were evaluated by the modified Rankin scale (mRS) after 3 months. Results There were no significant differences between the two groups in age, gender, vascular risk factors, stroke property and treatment principle. There were significant differences between the NIHSS and GCS at the first admission and the mRS scores at 3 months (P<0.01). The proportion of the patients with the history of diabetic mellitus in the random hyperglycemia group was significantly higher than that in the normal group (P<0.01).The random blood glucose levels were not correlated with the severity of stroke between the 2 groups of patients with the history of diabetes mellitus; the increased random blood glucose levels were significantly correlated with the severity and prognosis of stroke between the 2 groups of patients without the history of diabetes mellitus (P<0.01). Conclusions The increased blood glucose in patients with stroke without the history of diabetes mellitus in acute phase is an independent risk factor for the severity and prognosis. The increased random blood glucose in patients with stroke in acute phase may also suggest having the history of diabetes mellitus.

Doxorubicin-loaded PLGA nanoparticles (DOX-PLGA NPs) was prepared by double emulsion (W/O/W) solvent evaporation method with the biodegradable materials-poly (lactic-co-glycolic acid) (PLGA) used as carrier materials. Single-factor test was used to investigate the influence of the type and ratio of the organic phase, the amount of surfactant, PLGA concentration, the ratio of external water phase and oil phase (W/O), the ratio of doxorubicin and PLGA, ultrasonic time and stirring time on the preparation of nanoparticles. The best formulation and preparation conditions were optimized by orthogonal test based on single-factor test, evaluation indicator as particle size and entrapment efficiency, and the results were analyzed by overall desirability. And the in vitro release behaviors of the nanoparticles were studied as well. The size distribution, zeta potential, morphology of DOX-PLGA NPs were characterized by laser light scattering and transmission electron microscopy; encapsulation efficiency and releasing behavior of DOX-PLGA NPs in vitro were investigated by ultraviolet spectrophotometry. The results show that the DOX-PLGA NPs are regularly spherical in shape with the mean size of (189.2 +/- 5.3) nm, and the zeta-potential of the NPs is about (-28.32 +/- 0.52) mV. Drug loading and encapsulation efficiency are estimated to be (73.16 +/- 0.43) % and (1.51 +/- 0.07) %, respectively. The cumulative percentage of the drug released is 90.34%, and the in vitro release behavior made up of initial burst release and sustained-release could be described by the bidirectional kinetic equation. The results indicate that hydrophilic small-molecule drugs could be successfully entrapped into PLGA-NPs. With optimization of the formulation and preparation conditions, we obtained uniform and stable DOX-PLGA NPs with sustained release character in vitro and pH-sensitive property, which could provide the experimental basis for the development of a new anti-tumor sustained-release formulation.
