Objective To analyze the correlation between clinical features and renal dysfunction in patients of acute lacunar infarction with progressive cerebral microbleeds (CMBs). Methods Two hundred and sixty-five patients with first-episode acute lacunar infarction were selected. The serum creatinine was measured within 24 h of admission and the estimated glomerular filtration rate (eGFR) was calculated. The brain MRI (including gradient-echo images) was examined within 2 d of admission and after 1 years of follow-up, respectively. The progressive CMBs was assessed with microbleeds anatomical rating scale (MARS), and the patients were divided into progressive CMBs group (progressive group, 42 cases) and non progressive CMBs group (non progressive group, 223 cases). The clinical features of 2 groups were compared and the correlation between progressive CMBs and renal dysfunction was analyzed. Results The age, 24 h pulse pressure, incidences of renal dysfunction and CMBs in progressive group were significantly higher than those in non progressive group: (69.8 ± 5.8) years vs. (61.5 ± 4.9) years, (63.3 ± 3.1) mmHg (1 mmHg=0.133 kPa) vs. (51.8 ± 4.2) mmHg, 69.0%(29/42) vs. 39.9%(89/223) and 57.1%(24/42) vs. 25.1%(56/223), and the platelet was significantly lower than that in non-progression group:(168 ± 35) ×109/L vs. (189 ± 40) ×109/L, and there were statistical differences (P<0.05 or<0.01). The Logistic regression analysis result showed that renal dysfunction and CMBs were Independent risk factors of progressive CMBs (OR = 1.571 and 1.054, 95% CI 1.042 - 2.493 and 1.010 - 1.142, P<0.05). Conclusions The rate of renal dysfunction is higher in patients of acute lacunar infarction with progressive CMBs, and progressive CMBs are associated with renal dysfunction.

Objective To investigate the effects of sevoflurane and propofol on postoperative cognitive function after abdominal surgery for elderly patients with diabetes. Methods Seventy diabetic patients (aged 60~75 yr, ASAⅠorⅡ) underwent abdominal surgery and are included in the research. Diabetic patients were randomly divided into two groups (n=35): sevoflurane group(group DS) and propofol group (group DP). MMSE score, the attachment test, words memory test and Stroop color word test were carried and the results were recorded before operation (T1), postoperative 24 h (T2), 48 h (T3) and 1 w (T4). Results Compared with T1, patients′ MMSE score reduced at T2 and T3. Time spent in attachment test is longer at T2 and T3. Mistaken incidences in Stroop color words test 1, 2 and 3 are higher and time longer at T2. Time spent on Stroop color words test 2 and 3 is longer in T3. Words memory test reveals decline at T2 and T3, whose difference is statistically significant (P < 0.05). Cognitive dysfunction incidence in the two groups shows no statistical significance (P > 0.05). Conclusion Sevoflurane and propofol can result in postoperative cognitive dysfunction for elderly patients with diabetes within 48 h after abdominal surgery, there were no difference between the effects of them.
