Objective To investigate the relationship between gene polymorphism of factor VII R353Q (FVII R353Q) and cerebral palsy for Han Chinese children. Methods Polymerase chain reaction-restricted fragment length polymorphism were used to determine genotype and allele of R353Q gene in 160 children with cerebral palsy and 137 normal children. Results The genotype of FVII R353Q is close to Hardy-Weinberg equilibrium in both CP group and control group (P>0.05). There was not significant difference in the distribution of the allelic frequency and genotype of FVII R353Q between the both groups (P=0.436, P=0.182, respectively). Conclusion The gene polymorphism of FVII R353Q is not significantly related with cerebral palsy for Han Chinese children.

Objective To discuss the possible enteric nervous pathogenesis in gastritis related GI motor disorders on the expression changes of protein gene product9. 5 in neurons from the gastric walls of gastritis rat model. Methods 35 clean grade Wister rats were randomly divided into 3 groups, which included gastritis group A (n =10), gastritis group B(n =15) and control group(n =10). Rats in gastritis group A and B received gastric perfusion of HP and the mixture of 2% aspirin and 0. 6N hydrochloric acid respectively. The control group only received gastric perfusion of saline. All of the rats were killed and the gastric mucosal tissues were obtained for the pathological and HP examination. After immunohistochemical pretreatment, the tissues were stained with PGP9. 5 and at the same time the maximum diameter (Dmax, μm), mean area(μm2) and mean optical density (nm) of the neurons from the gastric walls were compared among the groups with Image-Pro Plus professional image analysis system. Results In gastric group A, HP could be found sparsely in the mucous layer or gastric pits, and all of the rapid urease tests were positive. In the other two groups, HP could not be found, and all of the rapid urease tests were negarive. In both gastric group A and B, different grades of inflammatory cell infiltration with active inflammation signs could be found in the deep layers of mucosa, while the control group was normal. The expression mean area, mean optical density of neurons from the gastric wall of rat in group A[(77. 10 ±48. 46) μm2, (53. 25 ±41.40) nm] or B [(73. 92 ± 39. 60) μm2, (45.33 ± 33.20) nm] was obvious lower than control group [(143.51 ± 29. 84) μm2, (85. 00 ± 14. 32) nm], while there was no significant difference between gastric group A and B (P ＞0. 05) (table 1). Conclusions Hp and NSAIDs might cause gastritis and decrease the PGP9. 5 expression of Neurous from gastric walls. The decrease of PGP9. 5 expression of neurons from the gastric wall might contribute to the pathogenesis of GI motor disorders or symptoms of functional dyspepsia.

Objective To investigate the expressions of stern cell markers CD133,nestin and CD44 in malignant melanoma and their significance.Methods Tissue samples were obtained from 30 patients with malignant melanoma and 30 patients with intradermal nevus.The expressions of three markers were immunohistochemically detected in the samples.Results In malignant melanoma specimens,the expression rate of CD133,nestin and CD44 was 53.33%(16/30),80.00%(24/30)and 20.00%(6/30),respectively,significantly difierent from that in intradermal nevus specimens [23.33%(7/30),53.33%(1 6/30)and 0,respectively,all P＜0.05].The percentage of cells positive for CD133,nestin and CD44 was 2.98%±5.62%,34.92%±34.89%and 1.28%±3.26%,respectively,in malignant melanoma specimens.0.10%±0.21%,7.26%±13.13%and 0,respectively,in intradermal nevus specimens;there was a significant difierence between the two groups of specimens(all P＜0.05).In malignant melanoma and intradermal nevus,the expression intensity of CD133.nestin and CD44 showed no significant correlation with patients'sex.age or disease course(all P＞0.05).ConclusionsCD133,nestin and CD44 are highly expressed in malignant melanoma,but weakly expressed or absent in intradermal nevus,suggesting that tumor stem cells might exist in malignant melanoma tissue.

Objective To find the possible pathogenesis of enteric nervous system, gut hormone and gastric Cajal interstitial cell ( ICC ) in gastritis related gastrointestinal ( GI ) motor disorders on the changes of protein gene product 9. 5 in neurons , mucosal expression of C-kit, gastrin and somatostatin from the gastric wall of gastritis rat. Methods 45 rats were divided into 3 groups which included gastritis group A, gastritis group B and control group. Rats in gastritis group A were fed with Hp Sydney Strain 1, the mixture of 2% aspirin and 0. 6N hydrochloric acid was fed in gastritis group B. The control group only received saline. All of the rats were killed and mucosal tissue was obtained from antrum and greater curvature of the gastric body. Pathological and Hp examination were performed in the tissue slides, and then it was stained to check PGP 9. 5, gastric body's mucosal expression of C-kit, antrium's mucosal expression of gastrin and somatostatin. The cell body, the maximum diameter (Dmax, μm), mean area( μm2) and optical density (nm), integral optical density of the gastrin and somatostatin in the C-kit expression positive neurons from the gastric wall were compared among the groups. Result The mean area and optical density of PGP 9. 5 expression in neurons from the gastric wall of rat in group A or B were obviously lower than that of the control group ( P ＜0. 01 ), while there was no difference between gastric group A and B ( P ＞0. 05). Gastric group A had higher GAS expression than control group, while SS expression was lower than control group( P＜0. 05). There was no difference between group B and the control group in the two variances( P ＞0. 05).By linear correlation analysis, it showed that SS was negatively correlated with GAS ( r = - 0. 333, P ＜0. 01 ). The distributive area and diameter of cells with C-kit expression in both group A and B were significantly smaller than that in the control group ( P ＜ 0. 05 ), while there was no obvious difference between group A and B ( P ＞ 0. 05 ). There was no difference of integral optical density of the C-kit expression positive neurons among the three groups. Conclusions Hp infection and NSAIDs might cause gastritis and had influence on the structural changes of neurons from gastric wall and ICC. Hp infection could obviously inhibit SS excretion from antrum mucosa while increase Gastrin excretion. NSAIDs induced gastritis had little influence on GAS and SS.
