Objective To observe the curative effects of treatment with Edaravone for acute massive cerebral infarction.Methods 48 patients with acute massive cerebral infarction were randomized into the treatment with Edaravone group(Edaravone group,24 patients) and the conventional treatment control group(control group,24 patients).Two groups patients were admitted conventional treatment for cerebral infarction.Edaravone group patients were admitted with Edaravone 30 mg into 100 ml saline infusion introvenously,twice a day,linked 20 ～ 25 d.Respectively before and after the treatment,neurologic function dificit score(NDS),plasma fibrinogen(Fib) content,coagulation blood function,activity of superoxide dismutase(SOD) were examined.The clinical efficacy was compared between the two groups.Results NDS of tow groups after treatment were significantly lower than those of before treatment,activity of SOD were significantly increased than those before treatment(all P0.05).Significant efficiency ratio of the Edaravone group(87.5%) was significantly higher than that of the control group(45.8%)(P

Objective To investigate the gastric empty and electrogastrogram(EGG) in patients with renal insufficiency before and after hemodialysis, and to study the enteric nervous system (ENS) in experimental acute renal failure rats.Methods The comparisons of gastric emptying and EGG before and after hemodialysis were carried out in 15 patients with uremia who have gastrointerstinal symptoms. Acute renal failure models were also established. The neuroplexus of ENS and levels of some gut hormones were investigated. Results The EGG and gastric emptying were abnormal in patients with uremia before hemodialysis, but improved after dialysis. The neuroplexus of ENS with positive nitric oxide synthase(NOS) staining in rats with acute renal failure was significantly decreased. The levels of gastrin, vasoactive intestinal peptide and motilin in rats with acute renal failure were (159.1?55.6)?g/L, (121.6?48.9)pg/L, and (6.32?3.55)pmol/L, respectively, which were significantly different from those of the control group(P

Objective; To investigate the stress distribution in implant-bone interface with different pitches by three-dimension finite element analysis method in order to decide the best design of thread parameters for stress distribution. Methods: Built three-dimension finite element models of partial mandible and dental implant with superstructure. The stress distributions in bone and three kinds of implants whose pitches were 0.6, 0.8 and 1.0 mm respectively, under axial and oblique 45 degree to axle concentrated load. Data were analyzed by Cosmos/works software. Results;The maximal Von-Mises stress, tensile stress and compressive stress of implant with 0.8 mm pitch were lower than others, the stress distribution was even. The stresses in the same model under oblique load were much higher than those under axial load. The stress concentrated more on implant neck, upper part of cortical bone and the lowest thread on implant. Conclusion; The pitch of implant has effect on stress distribution in implant-bone interface and the transmission of occlusal force. The lower threads on implant should be cut to avoid the concentration of stress, and the non-axial force should be reduced as possible as we can or avoided when we design and make implant denture.

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.
