Objective To compare the effect of Solitaire AB and Enterprise stent-assisted endovascular embolization of intracranial wide-necked aneurysms. Methods The clinical data 218 patients with intracranial aneurysm treated with Solitaire AB stent or Enterprise stent in Guangdong General Hospital from January 2012 to December 2014 were analyzed retrospectively. Seventy patients were treated with Solitaire AB stents and 148 were treated with Enterprise stents. They were followed up after procedure (2 months to 2 years). The Raymond grade and the modified Rankin scale (mRS)scores were used to compare the efficacy of the 2 kinds of stents. Results There were no significant differences in patients before procedure in the Hunt-Hess grade (Z = 1. 550,P = 0. 121),Fisher grade (Z =1. 537,P =0. 124),aneurysm size (Z =0. 192,P =0. 848),and position (χ2 = 0. 337,P = 0. 736)between the 2 stent groups,while there were no significant differences in patients after procedure in the instant Raymond grade (Z = 0. 682,P = 0. 495), follow-up Raymond grade (Z = 0. 206,P =0. 837),and mRS score (P =0. 662)between the 2 stent groups. Further multivariate Logistic regression analysis showed that the stent type (Solitaire AB stent or Enterprise stent),Raymond grade follow-up grade (OR,0. 029 ,95% CI 0. 126 - 0. 199,P = 0. 661 ),and postoperative mRS score (OR,2. 000,95% CI 0. 204 - 19. 603,P = 0. 552)had no influence on the
prognosis. Conclusions In the assisted embolization of intracranial wide-necked aneurysms using the Solitaire AB and Enterprise stents,the effects of both stents are good in the assisted embolization of intracranial wide-necked aneurysms.

Objective To observe the effects of comprehensive measures of changing grain,selenium supplementation,off-site education and resettlement on prevention of children's Kashin-Beck disease in Aba state.Methods Fifty eight villages in Aba Kashin-Beck disease areas were chosen as intervention points in Aba state Sichuan province from 2007 to 2011.Based on the implementation of prevention and control measures,the villages were divided into off-site education + changing grain + selenium supplementation group and resettlement + off-site education + changing grain + selenium supplementation group,Geletuo town of Seda county,Ganzi state was selected as a control point,and right-hand anteroposterior X-ray examination(including the wrist) was carried out on children aged 6-13 from 2007 to 2011 annually.Clinical and X-ray diagnosis of Kashin-Beck disease was made in accordance with the Diagnostic Criteria of Kaschin-Beck Disease(GB 16003-1995).The effects of prevention and control measures were evaluated by comparing the child X-ray detection rate before and after the implementation of the measures.Results The average X-ray positive detectable rate of children in the intervention points was 2.07％(66/3181),2.72％ (69/2540),1.16％ (35/3017),0.56％ (19/3397) and 0.56％ (24/4273),respectively from 2007 to 2011,with a downward trend (x2trend =66.74,P ＜ 0.01).There was a downward trend in the average X-ray positive detectable rate of children in off-site education + changing grain + selenium supplementation group [1.60％(29/1809),2.63％ (39/1484),1.29％ (25/1941),0.64％ (15/2332),0.42％ (10/2379)] and resettlement + off-site education + changing grain + selenium supplementation group [2.70％ (37/1372),2.84％ (30/1056),0.93％(10/1076),0.38％ (4/1065),0.74％(14/1894)] (x2trend=30.97,35.19,all P ＜ 0.01).The average X-ray positive detectable rate of children in the intervention group was 0 from 2007 to 2010,and was 1.61％ (1/62) in 2011.The difference of X-ray positive detectable rate was not statistically significant in the control group in the 5 years from 2007 to 2011.The difference of children's X-ray positive detectable rate was not statistically significant between control group and intervention group.Conclusions The effect of taking changing grain,selenium supplementation,off-site education and resettlement comprehensive measures to prevent children's Kashin-Beck disease is not significant in those places where the state of Kaschin-Beck disease is not active.

4-coumarate coenzyme A ligase is a key enzyme of phenylpropanoid metabolic pathway in higher plant and may regulate the biosynthesis of ferulic acid in Angelica sinensis. In this study, the homology-based cloning and rapid amplification of cDNA ends (RACE) technique were used to clone a full length cDNA encoding 4-coumarate coenzyme A ligase gene (4CL), and then qRT-PCR was taken for analyzing 4CL gene expression levels in the root, stem and root tissue at different growth stages of seedlings of A. sinensis. The results showed that a full-length 4CL cDNA (1,815 bp) was obtained (GenBank accession number: KT880508) which shares an open reading frame (ORF) of 1 632 bp, encodes 544 amino acid polypeptides. We found 4CL gene was expressed in all tissues including leaf, stem and root of seedlings of A. sinensis. The expressions in the leave and stem were increased significantly with the growth of seedlings of A. sinensis (P < 0.05), while it in the root showed little change. It indicates a time-space pattern of 4CL gene expression in seedlings of A. sinensis. These findings will be useful for establishing an experiment basis for studying the structure and function of 4CL gene and elucidating mechanism of ferulic acid biosynthesis and space-time regulation in A. sinensis.

Objective To investigate the effects of pioglitazone on glucose metabolism,circulating resistin and adiponectin concentrations,and tissue resistin levels in rats with insulin resistance induced by free fatty acid (FFA).Methods A hyperinsulinaemic-euglycaemic clamp and[3-~3H]-glucose tracing technique were used in awake rats.Insulin-mediated peripheral and hepatic glucose metabolism,plasma resistin and adipenectin levels, resistin levels in tissues were assessed by hyperinsulinaemic-euglycaemic clamp with elevation of FFA by lipid infusion over 4 h in rats pretreated with or without pioglitazone.Results During steady-state of clamp,there was a significant increase in plasma FFA in lipid-infused group(L group)and pioglitazone-pretreated lipid-infused group(P/L group)compared to control rats(P＜0.01).The glucose infusion rate(GIR)in P/L group was significantly reduced as compared with controls[(20.6?0.9 vs 33.6?1.5)mg?kg~(-1)?min~(-1),P＜0.01], whereas the GIR was lower in L group than in P/L group[(12.6?0.8 vs 20.6?0.9)mg?kg~(-1)?min~(-1),P＜0.01].As compared with baseline,the hepatic glucose production(HGP)was significantly suppressed by 85% [(18.3?2.1 vs 2.7+2.4)mg?kg~(-1)?min~(-1) and (17.5?2.6 vs 2.6?1.0)mg?kg~(-1)?min~(-1),both P＜0.01]during the hyperinsulinaemic clamp in control and P/L groups.The suppressive effect of insulin on HGP was significantly blunted in L group[(17.3?2.1 vs 15.8?1.5]mg?kg~(-1)?min~(-1)].The rate of glucose disappearance(G_(Rd))was reduced in L group and P/L group compared with controls(P＜0.01).Baseline plasma resistin level was lower in P/L group than that in the controls[(7.8?1.3 vs 29.1?3.1)?g/L,P＜0.01].After lipid infusion,plasma resistin levels significantly increased in P/L group,but remained lower than that of L group [(18.1?3.8 vs 47.0?2.2)?g/L,P＜0.01].Baseline adiponectin level was higher in P/L group than those in the controls and L groups[(3.9?0.2 vs 2.8?0.1 and 2.6?0.2)mg/L,P＜0.01].After clamp,plasma adiponectin levels were decreased in L group and L/P group compared with baseline(both P＜0.05).In addition, the resistin level in the liver of P/L group decreased compared with the controls and L groups(both P＜0.05), whereas significantly increased in the muscle of L group.Conclusion Lipid infusion induces an acute insulin- resistance in vivo.Pioglitazone pretreatment partly prevents FFA-induced insulin resistance possibly by changing resistin and adiponectin levels.

Objective To investigate selcnium(Se) levels of environment and human body in Gaomi City and Zichuan District of Shandong. Methods Lijiaying Township in Gaomi City of Weifang City, Zhaili Township and Longquan Township in Zichuan District of Zibo City were selected. Two farming soil samples at different spot, local wheat and corn, residents nail samples from 3 to 4 families were collected in each natural village in the investigated towns. The contents of Se were detected by 2,3-diamino naphthalene fluorescence method. Results Se level of the soil, wheat, corn, and nails in Lijiaying [(0.054 ± 0.019), (0.022 ± 0.009), (0.018 ± 0.007), (0.365 ± 0.108)mg/kg] was significantly lower than that in Zhaili [(0.425 ± 0.080), (0.130 ± 0.043), (0.098 ± 0.026), (0.751 ± 0.134)mg/kg] and Longquan[(0.487 ± 0.153), (0.112 ± 0.030), (0.097 ± 0.029), (0.735 ± 0.145)mg/kg;P < 0.01]. In Lijiaying, Se was deficient in soil, wheat, corn(< 0.200, < 0.025 mg/kg), above Se deficiency diagnosis and below Se-adequate level in the nail, while in Zhaili and Longquan, the Se level in the soil (0.425, 0.487 mg/kg), wheat(0.130, 0.112 mg/kg), corn (0.098, 0.097 mg/kg), nails (0.751, 0.735 mg/kg) was adequate (≥0.400 mg/kg). Conclusions The external environment is Se-deficient in Lijiaying, Se-adequate in Longquan and Zhaili. The selenium level in human body is consistent with the external environment.

BACKGROUNDThe cause of the adjacent segment degeneration (ASD) after fusion remains unknown. It is reported that adjacent facet joint stresses increase after anterior cervical discectomy and fusion. This increase of stress rate may lead to tissue injury. Thus far, the load rate of the adjacent segment facet joint after fusion remains unclear.

METHODSSix C2-C7 cadaveric spine specimens were loaded under four motion modes: Flexion, extension, rotation, and lateral bending, with a pure moment using a 6° robot arm combined with an optical motion analysis system. The Tecscan pressure test system was used for testing facet joint pressure.

RESULTSThe contact mode of the facet joints and distributions of the force center during different motions were recorded. The adjacent segment facet joint forces increased faster after fusion, compared with intact conditions. While the magnitude of pressures increased, there was no difference in distribution modes before and after fusion. No pressures were detected during flexion. The average growth velocity during extension was the fastest and was significantly faster than lateral bending.

CONCLUSIONSOne of the reasons for cartilage injury was the increasing stress rate of loading. This implies that ASD after fusion may be related to habitual movement before and after fusion. More and faster extension is disadvantageous for the facet joints and should be reduced as much as possible.
