Objective To explore the incidence of G-6-PD deficiency in Dongguan District,Dongguan,Guangdong province. Methods Cord blood was obtained in 9676 cases of live births. G6PD/6PGD ratio was measured. Results Two hundred and sixty-five cases were diagnosed as G-6-PD deficiency giving an incidence of 2.74%. The incidence in male (4.07%,230/5646) was significantly higher than that in female (0.875,35/4030) ( P

0. 05 ). For detection of pancreatic duct dilation and lymph node metastasis, EUS was better than CT ( P=0.039,P=0.004). The accuracy of EUS in determing peripancreatic fat infiltration and organic invasion was correlated with tumor size (P=0.015,P=0.022) , pancreatic duct dilation was correlated with the location of tumors ( P

Objective To explore the correlation between oxidative stress and the occurrence and progression of diabetic complications in the patients with diabetes. Methods The content of 24 h urinary 8-hydroxy-deoxyguanosine (8-OhdG) in diabetes mellitus (DM) group, diabetic nephropathy (DN) group, diabetic retinopathy (DR)group, diabetic foot(DF) group, diabetic neuropathy (DNP) group and control group were detected, and analyzed. Results The content of 24 h 8-OhdG in DM group, DN group, DR group, DF group, DNP group were significantly higher than that in the control group (P ＜ 0.01), and that in DN group, DR group, DF group, DNP group were significantly higher than that in DM group(P ＜ 0. 01), but the content of 24 h 8-OhdG among DN group, DR group, DF group and DNP group was not statistically signiticant(P ＞0. 05). Conclusion The correlation between the occurrence of diabetic and its complications oxidative stress and the Ievel of oxidative stress in the body was positive related.

Objective To study the effects of Vitamin D (VitD) supplementation on growth and immune function in neonatal mice.Methods A total of 120 mice were divided into four groups (30 mice in each group) according to dose of VitD.The high-dose group,medium-dose group and low-dose group was given 3.44,1.72,0.86 IU VitD drops,respectively.The control group was not treated with VitD drops.Rat body weight,level of peripheral blood 25-(OH)D3 were observed.The cellular immune function (determined by using delayed hypersensitivity reaction experiment),humoral immune function (assessed by antibody producing cells counts and HC50 determination) and mononuclear-macrophage phagocytic function (assessed by mouse peritoneal macrophage phagocytosis of chicken red blood cells test and carbon clearance test) were detected.The flow cytometry assay was carried out to differentiate T lymphocyte subsets.Results With the increase of dose of VitD,levels of peripheral blood 25-(OH)D3 and calcium ion were gradually increased,there were statistically significant differences when compared with the control group(P＜0.05);the body weight and body length were gradually increased,while no statistically significant difference was found among the groups treated with VitD(P＞0.05).Compared to the control group,the toes swelling,phagocytic percentage,number of antibody producing cells,serum soluble HC50 in the high-dose group and medium-dose group were increased significantly,while carbon clearance test phagocytic index were decreased significantly (P＜0.05).With the increase of dose of VitD,the number of CD4+,CD8+ T lymphocytes and the CD4+/CD8+ ratio were gradually increased.Conclusion VitD could promote the growth and development of offspring mice,and enhance the immune function of the body.

Objective To design pedometer shoes through wireless transmission step calculation.Methods The transmitting terminals in the soles acquired the pressure signals,and then the signals were transmitted to the SCM after conversion,amplification and comparison.AT89S52 SCM was used for step calculation and then the results were sent to the receiver through nRF905.Results The receiver had three modes,such as the step-calculation mode with the time and step calculation result displayed,the running mode with the distance displayed and the function of stopwatch,and the prompt mode with the distance and consumed power displayed.Conclusion The wireless embedded pedometer shoes are multifunctional,easy to operate and reliable.

Objective To investigate if vascular endothelial growth factor-D(VEGF-D) and endostatin(ES) promote angiogenesis in colorectal cancer(CRC). Methods One hundred and five patients undergoing CRC surgery were enrolled in this study. CRC and normal tissue microarray were produced and measured for VEGF-D and ES by immunohistochemmical staining.Results VEGF-D and ES expression were stronger in CRC tissues than in control normal mucosa. MVD was higher in cancer tissues than in normal ones. ES down-regulated expression was associated with less invasiveness, positive lymph node metastasis, distant metastasis and in cases of early Dukes′ stage, while the expression of VEGF-D in corresponding tissues was on the opposite to ES. MVD increased along with tumor invasion, lymph involvement, distant metastasis and late Dukes′ stage. Conclusions VEGF-D in accord with ES promotes the angiogenesis and progression of CRC.

Objective To compare the effects of electroacupuncture (EA) at different acupoints on the neuroethology and expression of neurocan after focal cerebral infarction in rats. Methods The healthy male adult Sprague-Dawley rats were randomly divided into sham group (n=5), model group (n=20), Shuigou-Baihui (SB) group (n=20), Ganshu-Shenshu (GS) group (n=20) and Zusanli-Quchi (ZQ) group.All the rats were modeled with middle cerebral artery occlusion (MCAO) except sham group, and were randomly divided into 5 sub-groups as 1 d, 3 d, 7 d, 14 d and 21 d after cerebral ischemia. Their neuroethology was evaluated with Longa's score, and the expressions of neurocan mRNA and protein were detected with RT-PCR and immunohistochemistry in ischemic cortex. Results No dysfunction was found in the sham group. The neurological function recovered gradually 3 d after modeled, and improved significantly 7~21 d after modeled in each EA group compared with those in the model group (P<0.05). The expression of neurocan mRNA and protein gradually increased 1 d after modeled in the model group, peaked 14 d after modeled, and remained high level 21 d after modeled (P<0.01). The expressions of neurocan mRNA and protein were less in each EA group than in the model group 3 d after modeled (P<0.05), and were less in the SB group and GS group than in ZQ group (P<0.05). Conclusion The expression of neurocan increased significantly in ischemic cortex. EA may down-regulate the expression of neurocan after acute cerebral infarction, and improve the neuroethology. EA at SB and GS is more effective than at ZQ.

Objective To investigate the inhibitory effect of bone marrow mesenchymal stem cells ( BMMSC) on the inflammatory response of microglial cells .Methods The samples were divided into four groups .Group I:microglial (BV-2) cells were cultured in DMEM (high glucose).Group II: BV-2 cells were cultured in DMEM containing lipopo-lysaccharide (LPS).Group III:BV-2cells and BMMSCs were co-cultured in DMEM.Group IV: BMMSCs were cultured in DMEM containing LPS .The growth state and ultrastructure of BV-2 cells were observed and the changes of TNF-αex-pression were detected .Results Different cell densities of BV-2 cells were observed under the optical microscope in an or-der from high level to low level:group I >group III >group II.The expressions of TNF-αwere:group Ⅱ >groupⅢ>group Ⅰ.Ultrastructural observation of BV-2 cells showed that there were a large number of swollen mitochondria and endoplasmic reticulum , some of them showed vacuolization .No BV-2 cells with multiple hucleoli were found in the group II indicating the absence of active cell growth .At the same time, cytolysis was observed only in the group II .The growth of BV-2 cells in the group III was better than that in the group II .Conclusions BMMSCs can inhibit inflammatory response of microglial cells, therefore, play a neuroprotective role.
