Tianjin Medical Journal 2010;38(1):29-31
Objective: To investigate the effect of different concentrations of dextrose transfusion on cerebral glucose metabolism in pediatric neurosurgical operations. Methods: Sixty anesthetized children undergoing selective cerebral tumor resection were randomly divided into three groups: Ringer lactate solution group (A, n = 20), 2.5% dextrose lactated Ringer's solution group(B, n = 20), 1% dextrose lactated Ringer's solution group (C, n = 20). All the hemodynamic data were recorded during anesthesia. The values of blood glucose and lactic acid were collected before intubation(T_a), 2 hours after opening cerebral dura mater (T_b) and the end of operation (T_c). The catheters for microdialysis were punctured into normal brain tissue. The contents of glucose and lactic acid were determined in the collected intercellular fluid by biochemical analysis instruments at T_A and T_B respectively. Results: There were no differences in heart rate(HR), mean arterial pressure(MAP) and arterial oxygen saturation (SpO_2) among three groups(P > 0.05). There were no differences in blood glucose at T_a between three groups(P > 0.05). The values of blood glucose at T_b and T_c were B group>C group>A group(P < 0.05). The values of blood glucose were higher at T_b and T_c than that of T_a in three groups(P < 0.05). There were no differences in blood lactic acid among three groups(P > 0.05). There were no significant differences in values of glucose and lactic acid in the collected intercellular fluid among three groups(P > 0.05). Conclusion: Transfusion of Ringer lactate solution or low concentration dextrose solution will increase blood glucose in pediatric neurosurgical operations, but still in the normal range, which has a little influence on blood lactic acid, glucose and lactic acid in brain intercellular fluid. It is a safe choice during neurosurgical operation.

4.The advances of lens extraction for primary angle closure glaucoma
Chinese Journal of Experimental Ophthalmology 2012;30(8):761-764
Development of primary angle closure glaucoma (PACG) is closely related to the changes of the position and morphology of the lens owing to a shallow anterior chamber,pupillary blockage and angle closure.Lens extraction can deepen the depth of the anterior chamber and resolve the pupillary blockage,and therefore increase the outflow of aqueous fluid.Furthermore,the combination of lens extraction with goniosynechialysis can reopen the closed anterior chamber angle and relieve peripheral anterior synechia of pupil,with a better clinical effectiveness for primary angle closure glaucoma.Recently,the studies related to lens extraction for primary angle closure glaucoma have madc great progression,especially its mechanism and efficacy,and of course some existing problems of lens extraction are concerned.In this review,the relationship between lens and primary angle closure glaucoma,the clinical effectiveness of lens extraction for primary angle closure glaucoma,the safety evaluation of lens extraction and goniosynechialysis were summarized.

6. Effect and mechanism of catechin on experimental atherosclerosis in quails
Chinese Pharmaceutical Journal 2013;48(3):181-185
OBJECTIVE: To study the effect and mechanism of catechin on experimental atherosclerosis in quails. METHODS: Atherosclerosis model in quail was established by high fat diet. The serum and tissue lipid contents were detected with enzyme method. The atherosclerotic plaque lesion of aorta was observed by naked eyes and under light microscope. The serum superoxide dismutase (SOD) and malondiadehyde (MDA) in quail were observed with microcontent fast detecting method. RESULTS: After eight weeks continuous administration, the serum levels of triglyceride (TG), total cholesterol (TC) and low density lipoprotein cholesterol (LDL-C) (P<0.05, P<0.01) were decreased in all catechin groups, the serum level of high density lipoprotein cholesterol (HDL-C) was increased in middle dose catechin group (P<0.05) compared with model group, while the serum levels of HDL-C in high and low dose catechin group showed trend of increase (P≤05). At the same time, TC and TG in the liver, myocardial and aortic wall and the degree of atherosclerotic lesion in aorta and fatty degeneration of liver in catechin groups were reduced (P<0.05, P<0.01), the level of the serum SOD was increased while MDA level was reduced (P<0.05, P<0.01). CONCLUSION: Catechin can prevent atherosclerotic lesion probably through decreasing blood lipid level and antioxidation.

9. Clinical study on Lp-PLA2 levels in different types of cognitive impairment
Chinese Journal of Cerebrovascular Diseases 2011;8(5):243-247
Objective: To evaluate the expression levels of lipoprotein-associated phospholipase A2 (Lp-PLA2) in various types of cognitive impairment. Methods: A total of 212 patients were included in the study. They were divided into mild cognitive impairment (MCI) (n = 46), Alzheimers disease (AD) (n = 58), vascular dementia (VD) (n = 84), and control (n = 24) groups after being screened and evaluated. The concentrations of plasma Lp-PLA2 of patients in each group were measured and compared. The correlation between the Lp-PLA2 level and dementia was analyzed through Cox proportional hazards model. Results: Circled digit oneThe Lp-PLA2 levels in the MCI, AD and VD groups were 45 ± 4 μg/L, 83 ± 15 μg/L, and 112 ± 22 μg/L, respectively, and they were higher than 34 ± 3 μg/L in the control group. The difference was statistically significant (P < 0.05). Circled digit twoThe Lp-PLA2 level was 93 ± 8 μg/L in men, and it was higher than 73 ± 13 μg/L in women in the AD group. The difference was statistically significant (P < 0.05). The Lp-PLA2 level in men was 127 ± 21 μg/L, and it was higher than 97 ± 10 μg/L in women in the VD group. The difference was statistically significant (P < 0.05). Circled digit threeThe Cox proportional hazards model showed that the Lp-PLA2 level was correlated with the high risk of dementia. The correlation of VD was the highest, then AD, and MCI was the lowest. Conclusion: High level of Lp-PLA2 has correlation with mild cognitive impairment, and has gender differences in patients with vascular dementia and Alzheimer's disease, it may be contributive to early diagnosis of cognitive impairment.
