The status of marine bioresources and the marine eco-environment issues were summarized and discussed, and the strategies for the development of Chinese marine bioresources in the future were proposed. The degradation of marine eco-environment and unreasonable exploitation of the resources resulted in acute decline of Chinese marine bioresources. The feasible stratagies for the sustainable use of marine bioresources should be to intensify the basic research on marine bioresources science, to strengthen the protection of the marine environment and conservation of marine living resources, and to exploit and utilize marine bioresources scientifically and reasonably by using high-technology including marine biotechnology.

Objective To examine the independent effect of depression on activities of daily living of patients with mild cognitive impairment (MCI). Methods Data were obtained through the face-to-face interview. Totally 154 elderly patients that were screened from 552 old people by the Montreal Cognitive Assessment (MoCA) were diagnosed as MCI. They were investigated with the Geriatric Depression Scale, and instrumental ability of daily living (IADL) were measured by the Functional Activities Questionnaire. The effect of depression on IADL of patients with MCI was analyzed by logistic regression analysis. Results The prevalence of depressive symptoms among Chinese elders with MCI was 31.82％. The scores of Medical Outcomes Study Social Support Survey, and Functional Activity Questionnaire of depression group and non-depression group were significantly different (P<0.05) . Logistic regression analysis showed that scores of Functional Activity Questionnaire was positively associated with the scores of Memory Inventory for the Chinese (OR=1.36, 95％ CI: 1.15-1.61) and depression (OR=6.19, 95％ CI:2.07-18.55) . Conclusion The prevalence of depression in elderly patients with MCI was high. Depression would significantly reduce the IADL of the old patients with MCI. Medical workers should be aware of the extent and impact of depressive symptoms in MCI and take active measures in evaluating and treating the depressive symptoms.

OBJECTIVETo investigate the effects of chronic stress on the spatial learning-memory and the role of glial cell line-derived neurotrophic factor (GDNF) of prefrontal cortex (PFC) and hippocampus (HP) in different age mice.

METHODSThe chronic stress model mice in 21 days with multiple chronic unpredictable stressors were applied. The spontaneous behavior and spatial learning-memory ability of mice were tested, using Open field and Morris water maze task, and the expression of GDNF in HP and PFC were detected by immunohistochemical method.

RESULTSCompared with young mice, the spontaneous behaviors were significantly decreased and the spatial learning-memory function were significantly decreased (P < 0.05, P < 0.01) in aged mice. The GDNF expression in the CA3, DG of HP and PFC were significantly reduced in aged mice (P < 0.05, P < 0.01). After chronic stress, the spontaneous behaviors were remarkably decreased and the ability of spatial learning-memory of the stress group mice were significantly decreased (P < 0.05, P < 0.01) compared with those of the control group mice. The expression of GDNF in HP and PFC were remarkably reduced (P < 0.05, P < 0.01) in stress group mice. The aged stress mice had more serious changes after chronic stress.

CONCLUSIONThe brain aging and chronic stress in mice causes behavioral changes and the damage of spatial learning-memory function, and which may be nearly related to the expression of GDNF in HP and PFC.

To study the protective effect of astragalus saponin extracts (AS) on kidneys of diabetic rats. Totally 32 diabetic rats induced by streptozotocin (STZ) were divided into AS high and low dose groups, the positive control group and the model group (DM group) and orally administered with 50 mg x- kg(-1) x d(-1) AS 200, 25 mg x kg(-1) x d(-1) valsartan, 10 mL x kg(-1) x d(1) physiological saline, respectively. Another 8 healthy rats were collected in the normal control group (NC group, physiological saline 10 mL x kg(-1). d(-1)). All rats were treated for consecutively 6 weeks. After the administration, the body weight was measured every week, the concentration of blood glucose was monitored on week 2, 4 and 6. The total urine and total urinary protein (U-TP) in 24 h were measured by the metabolic cage method on week 6; At the end of week 6, blood samples were collected from hearts to detect blood urea nitrogen (BUN), serum creatinine (Scr), uric acid (UA) , total cholesterol (CH) triglyceride (TG) by biochemical methods. Kidneys were collect to calculate the kidney hypertrophy index and observe the pathological sections. The laboratory results show that in the DM group, the blood glucose, metabolic cost in 24 h, kidney hypertrophy index, U-TP, BUN, Scr, UA, TG were significantly higher than that in the NC group (P < 0.01, P < 0.05) , with significant pathological changes; After the intervention with AS, the metabolic value in 24 h, kidney hypertrophy index, U-TP, BUN, Scr, UA, TG were significantly lower in the high dose group (P < 0.01, P < 0.05), and the kidney hypertrophy index, BUN, Scr, UA, TG in the low dose group were also significantly lower (P < 0.05), with slight reduction in renal pathological changes in both groups. In conclusion, Astragalus saponin extracts have a certain protective effect on kidneys of diabetic rats.
