Objective To evaluate the morbidity and the influence factors of the geriatric syndrome in the elderly inpatients. Methods The characteristics of comprehensive geriatric assessment of180 elderly inpatients (83 male and 97 female) with age older than 65 in geriatric department from November 2014 to November 2015 were analyzed. Results Of 180 elderly patients, the incidences of visual loss, multiple co-morbidity, polypharmacy, impairment in activities of daily living, urinary incontinence, chronic constipation and chronic pain were 86.11%(155/180), 85.56%(154/180), 82.78%(149/180), 56.11%(101/180), 49.44%(89/180), 46.67%(75/180) and 42.22%(76/180). Female patients had more incidences compared with male in urinary incontinence [56.70%(55/97) vs. 40.96%(34/83)], chronic pain [56.70% (55/97) vs. 25.30%(21/83)] , impairment in activities of daily living [64.95%(63/97) vs. 45.78%(38/83)] and high risk of falling [43.30%(42/97) vs. 21.69%(18/83)], and there were significant differences (P<0.05). In addition, it was found that with the increasing of age, the incidences of hearing loss and chronic constipation, as well as medications were accordingly higher. When the patients′education level was higher, the incidences of urinary incontinence and impairment in activities of daily living were generally declined. Compared with non-diabetes mellitus group, diabetes mellitus group had higher incidences of comorbidities, multiple co-morbidity, medications, polypharmacy and impairment in activities of daily living:(10.59 ± 3.72) kinds vs. (8.29 ± 4.03) kinds, 94.59%(105/111) vs. 71.01%(49/69), (10.07 ± 3.77) kinds vs. (6.87 ± 3.07) kinds, 89.19%(99/111) vs. 72.46%(50/69), 62.16%(69/111) vs. 46.38% (32/69). With the increasing of the numbers of diabetes- related chronic complications, the incidences of visual loss, chronic constipation and multiple co- morbidity, comorbidities and medications were higher (P<0.05). Conclusions Geriatric syndrome such as visual loss, multiple co- morbidity, polypharmacy, impairment in activities of daily living and urinary incontinence are very common in the elderly inpatients. Elderly patients with diabetes mellitus are much easier to suffer from geriatric syndrome such as multiple co-morbidity, polypharmacy and impairment in activities of daily living.

AIM: To study the effects of Ginkgo biloba extract (GbE) on cerebral ischemia-reperfusion injury. METHODS: Cerebral ischemia-reperfusion injury was produced by 10 min or 20 min occlusion of bilateral carotid arteries followed by 5 d or 1 d reperfusion in gerbils. Ninety-five gerbils were divided into 4 groups: sham-operation, ischemia-reperfusion, GbE 50 mg*kg-1 and GbE 100 mg*kg-1 groups. Drugs were given intragastrically 2 d prior to ischemia and during reperfusion. The effects of GbE on the contents of calcium, sodium, water in cortex, and lipid peroxide(LPO) in brain hemispheres, as well as the density of neuron in hippocampal CA1 sector were observed. RESULTS: GbE could reduce the increase of calcium, sodium, water content in a manner of dose-depedance. The dosage of GbE 100 mg*kg-1 could decrease the content of LPO and the mortality, increase the density of neuron in hippocampal CA1 sector. CONCLUSION: GbE has protective effects on cerebral ischemia reperfusion injury.

Objective This study was aimed to investigate the expression of monocyte chemoattractant protein-1 (MCP-1) and vascular endothelial growth factor (VEGF) mRNA in rats with acute methanol poisoning. Methods Animal models of acute methanol poisoning in rats were duplicated using a plexiglas chamber exposed to a mixture of N2O/O2. Right atrium venous blood of rats were taken at each time point (2 h, 12 h, 24 h,3 d,1 w), and gas chromatography was used to determine the methanol concentration of the rat blood (n=5) . Then got brain tissue to extract total RNA and reverse transcription (n=3) . SYBRGreen real-time PCR was used to monitor the expression of MCP-1 and VEGF mRNA. Results (1) Results of methanol concentration determination:The blood methanol concentration of the low-dose group was significantly increased in comparison with that of the saline control group at 2 h and 12 h time points ( < 0.05) . In the high-dose group, the blood methanol concentration was increased significantly compared with the low-dose group as well as the saline group at 2 h, 12 h and 24 h time points ( < 0.05); (2) The expression of MCP-1 mRNA: The expression level of MCP-1 were significantly enhanced along with the time lapse after acute poisoning,and became most severely at 24 h. The expression levels of MCP-1 have significant differences in groups,of which high-dose group was higher than low-dose group at 2 h, 3 d and 1 w ( <0.05);(3) The expression of VEGF mRNA:The expression level of VEGF was significantly enhanced along with the time lapse after acute poisoning,and became most severely at 24 h. The expression levels of MCP-1 have significant differences in groups,of which high-dose group was higher than low-dose group at 2 h and 12 h ( <0.05) . Conclusion The expression levels of MCP-1 and VEGF mRNA were significantly enhanced, and the degree of poisoning was apparently related with the dose administered. MCP-1 and VEGF might play the important roles in the pathogenesis and progression of brain injured.
