International Journal of Cerebrovascular Diseases 2009;17(2):81-84
Objective To investigate the correlation between behavioural and psychological symptoms and cerebral white matter lesions (WMLs) in patients with Alzheimer's disease (AD). Methods Sixty patients with AD aged more than 60 years (AD group) and 40 age-, sex-matched subjects with normal cognitive function (control group) were recruited. data of cerebral CT were analyzed blindly. The sum of WMLs in 8 regions, such as bilateral frontal region, parieto-occipital region, temporal region, and subtentorial region, etc were used as the total score of WMLs, and the cerebrovascular lesions revealed on CT were detected. The AD group was assessed with the Neuropsychiatric Inventory (NPI). Results There were significant differences in total WML score (1. 450 ±2. 310 vs. 9. 640 ± 1. 566, P =0. 000), left frontal WMLs (0. 340 ± 0. 340 vs. 1. 720 ± 0. 248, P = 0. 001), fight frontal WMLs (0. 310 ±0. 560 vs. 1. 680 ±0. 312, P =0. 001), left parieto-occipital WMLs (0. 240 ±0. 360 vs. 1. 550 ±0. 244, P =0. 012), right parieto-oecipital WMLs (0. 140 ±0. 230 vs. 1. 450 ± 0. 231, P = 0. 006) and cerebrovascular lesions (0. 120 ± 0. 330 vs. 2. 230 ± 0. 378, P = 0. 002) hetwsen the AD group and the control group. Spearman correlation analysis showed that NPI was correlated with the total WML score (rs =0. 487, P = 0. 016), left frontal WMLs (rs =0. 490, P = 0. 014), right frontal WMLs (rs = 0. 502, P = 0. 014), left parieto-occipital WMLs (rs =0. 507, P =0. 012) and right parieto-occipital WMLs (rs =0. 521, P = 0. 014), and it was not correlated with the cerebrovascular lesions (rs = 0. 132, P = 0. 590).Conclusions WMLs and cerebrovascular lesions are essential in the onset of AD and disease development. WMLs are closely correlated with the behavioural and psychological symptoms in patients with AD.

Objective To investigate the effect of indomethacin on the protein expression profile of colorectal cancer cell line HCT116 xenografts in nude mice, and to screen the indomethacin anticancer-related proteins. Methods The nude mice with colorectal cancer cell line HCT116 xenograft were treated with or without indomethacin, and then the total proteins extracted from xenografts were separated and visualized by immobilized pH gradient two-dimensional gel (2-DE) electrophoresis. The differential expression proteins between the experimental and control groups were analyzed using PDQuest image analysis software, and identified by peptide mass fingerprinting based on matrix-assisted laser desorption ionization time of flight mass spectrometry and database searching. Results The 2-DE patterns with high resolution and reproducibility were obtained, displayed about 1100 protein spots in each gel, and the matching rate in the two groups was 96. 0% and 93. 6% , respectively. Thirty-one differentially expressed protein spots were found between the two groups, of which 25 spots decreased and 6 increased in the expression levels in the experimental group than in the control group. Eighteen peptide mass fingerprinting maps were obtained, and twelve proteins including galectin-1, annexin and trancription factor, were primarily identified after database searching, most of which were involved in tumor cell proliferation, invasion, apoptosis and immunity. Conclusions Indomethacin exerts its inhibiting effects on colorectal cancer through regulating multiple proteins expression directly or indirectly. The data will be helpful to elucidate the mechanism inhibiting cancer by indomethacin, and to find new targets of chemotherapeutic drugs.

Using inverted microscopy and circuit TV, the morphological type, diameter of arteriovenous anastomoses (AVAs) in 11 rabbit's ear chambers were observed. According the joining forms with arterioles and venules in 68 AVAs, there were 4 types: type Ⅰ 58.8%, type Ⅱ 19.4%, type Ⅲ 11.1%, type ⅣV 10.7%. The inner diameters of the AVAs when dialated, measured 36.6?1.67?m at their arterial ends, 16+0.6?m at their narrow points, 66?4?m at their venous ends.This study showed that dilation of AVAs in the rabbit's ear is a graded response which correlates with the rise in intravertebral canal temperature. Some AVAs have multiple venous segments which vary in diameters. It was observed that the behaviour were different after intravertebral canal warming.

Objective It has been known that NSAIDs can inhibit the growth of tumors through cyclooxygenase, but it is unknown that whether there are other mechanisms involved. It is essential to detect the effect of indomethacin for proliferation and apoptosis in the HCT116 and explore its anti tumor mechanism. Methods Human colon adenocarcinoma cell line HCT116 was treated with different concentration of indomethacin for 24 h and CDK 2,CDK 4, Bcl 2, Bax and p21 WAF1/CIP1 protein were detected by Western blot. Results Indomethacin down regulated the expression of CDK 2, CDK 4, Bcl 2 and up regulated the expression of p21 WAF1/CIP1 , however, the expression of Bax remained unchanged. Conclusions Inhibiting proliferation and inducing apoptosis contribute to the anti tumor activity of indomethacin by down regulating the expression of CDK 2, CDK 4, Bcl 2 and up regulating the expression of p21 WAF1/CIP1 .
