RESUMO
Objective To observe the Hp infection effect on blood lipid metabolism and oxidative stress through detecting acute cerebral infarction (ACI) with Helicobacter pylori (Hp) infection serum lipid and malondialdehyde (MDA) level and superoxide dismutase (SOD) activity.Methods Chose ACI 350 cases of ACI group,80 cases of control group and detected serum Hp-IgG antibody (by colloidal gold) and 14C urea breath test (by14 C-UBT).Used the American beckman coulter AU680 fullautomatic biochemical analyzer to detect the serum lipid and SOD activity (colorimetry),and used Shanghai now 752 visible spectrophotometcr (532 nm) to detect the serum MDA level (TBA).Results The Hp infection rate of ACI group (69.5 ％) was significantly higher than that in the control group (33.8％),the differences was statistically significant (x2 =18.882,P＜0.01).The differences in serum TC,TG,LDL-C and HDL-C levels were statistically significant (t=4.167 ～5.521,all P＜0.01) compared with Hp non-infection group.The serum MDA level and SOD activity of the control group and Hp infection group were statistically significant (F=34.891～46.613,all P＜0.01).Hp infection with Hp infection group to compare serum MDA level and SOD activity differences statistically significant (t=5.197,9.713,all P＜0.01),the Hp infection group and control group in comparative differences were statistically significant (t=3.173,8.228,all P＜0.01).Conclusion Acute cerebral infarction merger of HP infection,blood lipid metabolic disturbance in body increased and enhanced oxidative stress reaction,this may be intensified HP infection is one of the reasons for acute brain infarction dis ease.
RESUMO
<p><b>OBJECTIVE</b>To investigate the clinical effects of cervical disc prosthesis in patients of cervical spondylosis early, compared with the anterior cervical interbody fusion.</p><p><b>METHODS</b>Bryan disc prosthesis replacement applied in 21 case (22 levels) of cervical spondylosis, 27 patients (32 levels) were treated by the anterior interbody fusion. Clinic (JOA grade) and radiological (X-ray of bending, extending; left and right bending position) follow-up of 48 patients was performed preoperatively and postoperatively. Systemic radiographic study about stability and rang of movement (ROM) of replaced levels postoperatively was measured; meantime the ROM of adjacent levels of all cases was observed. CT or MRI scan were applied in 21 patients postoperatively to find out the pressure of the spine and heterotopic ossification in the replaced level.</p><p><b>RESULTS</b>There was no complication. Improvement in all case increased obviously, JOA score increased and stabilized postoperatively in all cases (P < 0.01). Replaced segment achieved stability and restored partial of ROM. There was no prosthesis subsidence or excursion. The adjacent ROM of the case treated by the anterior interbody fusion increased obviously (P < 0.01). No heterotopic ossification was found in the replaced level, but the deteriorated adjacent level of 1 case applied by the anterior interbody fusion occurred.</p><p><b>CONCLUSIONS</b>Bryan cervical disc prosthesis restore stability and partial motion to the level of the intact segment in flexion-extension and lateral bending in postoperational images; The adjacent ROM has not increased obviously. At the same time, it can achieve good short-term clinic effect in replaced level, compared with the anterior interbody fusion.</p>
