Biomechanical Test on Novel Arc Cervical Titanium Mesh with Endplate Ring / 医用生物力学

Objective To establish the instability model of goat cervical vertebrae, and test biomechanical stability of the novel arc cervical titanium mesh with endplate ring. Methods The anatomical data from cervical vertebrae of adult goats were measured, so as to select a new type of arch cervical titanium mesh with endplate ring which was suitable for goat cervical vertebrae. A total of 24 goats with preserved articular capsule, ligaments and intervertebral disc were randomly divided into 4 groups. Group A (n=6, normal group) didn’t receive any special treatment, while Group B (n=6, model group) received partial resection of C4 vertebrae as well as upper and lower intervertebral disc. On the basis of models in Group B, Group C (n=6, experimental group) was installed with the novel arch cervical titanium mesh and fixed by plate and screw, and Group D (n=6,control group) was installed with traditional straight titanium mesh and fixed by plate and screw. The ranges of motion (ROMs) for 4 groups of specimens during flexion, extension, left/right lateral bending, left/right rotation under 2.0 N·m load were measured, and their three-dimensional (3D) motion stability was tested. The displacement of Group C and Group D under 200 N compression force was measured, the stiffness was calculated, and the anti settlement ability of the whole specimen was tested. Results The ROMs of Group A in all directions were smaller than those of Group B,the ROMs of Group A were larger than those of Group C, and the ROMs of Group C during flexion were smaller than those of Group D (P<0.05). The stiffness of Group C was higher than that of Group D (P<0.05).The compression displacement of Group C was smaller than that of Group D(P<0.05). Conclusions Compared with the straight titanium mesh, the novel arc titanium mesh is more consistent with the physiological curvature of cervical verebrae, and has better stability than the traditional titanium mesh during the most frequent flexion activities of cervical verebrae. Moreover, compression displacement of the novel arc titanium mesh under short-term stress is smaller than that of the straight titanium mesh, and its postoperative anti-settlement is better than that of the straight titanium mesh, which is worthy of further experiment and clinical promotion.

Clinical features and correlative factors of Parkinson’s disease patients with REM sleep behavior disorder / 中国神经精神疾病杂志

Objective To analyze the clinical features of rapid eye movement sleep behavior disorder (RBD) in pa?tients with Parkinson’s disease (PD) and investigate correlative factors of RBD. Methods Sixty-three consecutive PD pa?tients were included and classified into PD+RBD group (n=28) and PD-RBD group (n=35) according to REM Sleep Be?havior Disorder Questionnaire (RBDQ-HK). The degree of motor symptoms was compared using Unified Parkinson Dis?ease Rating Scale (UPDRS) and Hoehn&Yahr (H-Y) grade, the incidence of non motor symptoms was compared using non motor symptoms questionnaire (NMSquest), and the cognitive function, anxiety, depression, daytime sleep were com?pared using Montreal Cognitive Assessment (MOCA), Beck Anxiety Inventory (BAI), Beck Depression Inventory (BDI), Epworth Sleep Scale (ESS) between the two groups. Results The incidence of RBD in PD patients was 44.4% (28/63). There were longer illness course ( χ2=12.733, P=0.002), older age (t=-2.292, P=0.025), and higher H-Y grades (χ2=7.014, P=0.008) in PD+RBD group, compared with those in PD-RBD group, but there were no significant differences in sex, onset age, onset form and levodapa dose equivalents (LDE) between the two groups. There were higher UPDRSⅡ,Ⅲ scores (t=-2.734, P=0.008; U=3.329, P=0.001) in PD+RBD group. Most of the non motor symptoms, including the gastrointestinal dysfunctions, psychiatric comorbidity and sleep disturbances were more frequent in PD+RBD group (P<0.05), and the incidence of anxiety and depression were higher (χ2=3.958, P=0.047; χ2=10.338, P=0.001), whereas there were no significant differences in cognitive function and daytime sleep between the two groups. In addition, constipation (OR=7.257), illness course (OR=5.389), UPDRS Ⅲ scores (OR=1.060) were correlative with RBD in PD patients. Con?clusion PD patients with longer illness course, older ages, and severe motor and non motor symptoms more likely suffer from RBD. Besides, constipation, long illness course and high UPDRSⅢscores may be risk factors of RBD.

Neuroprotective effect of taurine against acute cortical neuron injury induced by oxygen-glucose deprivation / 中国药理学与毒理学杂志

AIM Taurine was reported neuroprotective under several ischemic models in vivo. In this study, the direct effect of taurine against oxygen-glucose deprivation (OGD) inducing acute neuronal injury and the underlying mechanisms in vitro were investigated. METHODSFour hours OGD was used to induce in vitro ischemic injury in rat cortical neurons. Taurine 5, 10 and 20 mmol·L-1 was added 20 h before and during 4 h OGD period respectively. Mortality rate of neuron was assayed by MTT and flow cytometry methods. Level of neuronal [Ca2+]i was detected by Fura 2/AM loading. Amino acid concentrations in culture media were measured by high performance liquid chromatography. RESULTS Under OGD conditions, neuronal death was markedly increased, and the levels of neuronal [Ca2+]i and extracellular glutamate level were enhanced obviously. Taurine pretreatment obviously decreased the percentage of neuronal death induced by OGD. In addition, abnormal elevation of neuronal [Ca2+]i and extracellular glutamate level induced by OGD both were markedly repressed by taurine. CONCLUSION Taurine can alleviate rat cortical neuron injury induced by OGD, the mechanisms were likely due to repressing calcium overload and inhibiting excessive release or leakage of glutamate under such conditions.

Effect of taurine on acute ischemia-induced neuron apoptosis in rats / 中国药理学通报

Aim To investigate the effect taurine on ischemia-induced neuron apoptosis and its mechanisms. Methods Focal cerebral ischemia was induced by middle cerebral artery occlusion (MCAO). After 6 h permanent MCAO, mRNA expressions of Caspase-3/8 of rat brain were detected with real-time quantitative reverse transcriptase-polymerase chain reaction (real-time QRT-PCR). Oxygen-glucose deprivation (OGD) was used to induce an in vitro ischemia model. Primarily cultured cortical neurons were exposed to 4 h OGD. Intracellular calcium concentrations([Ca~(2+)]_i) was measured with fluorescent Ca~(2+) sensitive probe fura 2 acetoxylmethyl ester (Fura 2/AM). Neuronal apoptosis was assayed with flow cytometry of FITC-annexinV/propidium iodide binding 24 h after OGD. Results mRNA expressions of Caspase-3/8 were upregulated in MCAO model. [Ca~(2+)]_i and neuronal apoptosis were markedly increased in OGD model. Taurine pretreatment reduced the upregulation of mRNA expression of Caspase-3/8 in vivo and ameliorated calcium overload and neuronal apoptosis in vitro. Conclusion Taurine has neuroprotective effect against ischema-induced neuronal apoptosis. This is partly due to its effects on Caspase-3/8 and [Ca~(2+)]_i

Effects of whole body irradiation with X-rays on the expression of TfR on lymphocytes in spleens of mice / 吉林大学学报(医学版)

Objective: To explore effect of TfR on immune function after ionizing by investigating changes in TfR expression on splenic lymphocytes of mice after whole body irradiation (WBI) with different dose X-rays. Methods: Direct immunoflurescence antibodies and flow cytometry were used to examine the changes of TfR expression. Results: The cell number of TfR positive expression in spleens increased significantly at 24 hours and 72 hours after WBI with 75 mGy X-rays but the cell number of TfR positive expression in spleens decreased significantly at 24 hours after WBI with 1～6 Gy X-rays. The activity of IL-2, meanwhile, demonstrated a parallel change. Conclusion: These results suggest that the TfR enhances immune function in low dose ionizing radiation but suppresses immune function in high dose. The change of TfR expression may be due to the change of IL-2 activity caused by ionizing radiation.

Neuroprotective effect of taurine on focal cerebral ischemia in rats / 中国药理学通报

AIM To observe the protective effect of taurine on focal cerebral ischemia in rats. METHODS Male SD rats were divided at random into three groups, i.e. sham-operated, control and treatment group respectively. Before ischemia impairment, taurine(250 mg?kg -1?d -1)was administrated ip for one week in treatment group. A nylon suture was inserted into internal carotid artery to occlude the beginning of middle cerebral artery(MCAO). After 3 h permanent occlusion, neurology deficit score was evaluated. At 6 h, all animals were decapitated rapidly to get brain tissue. Brain infarct region was stained by 2,3,5-triphenyltetrazolium(TTC) and the size was measured by AUTOCAD. Contents of malondialdehyde(MDA) and nitric oxide synthase(NOS) and activity of superoxide dismetase(SOD) in brain tissue were detected by spectrophotometer. Expressions of iNOS and inter-cellular adhesion molecule-1 (ICAM-1) were observed through immunohistochemistry method. RESULTS Compared with the control group:Taurine can ameliorate neurological deficit score and decrease infarct volume induced by MCAO. Taurine improved the activity of SOD, but did not affect NOS activity in the infarct without affecting MDA content after 6 h MCAO. Taurine decreased the positive expression of ICAM-1 significantly in brain slice. CONCLUSION The results suggest that taurine may reduce expression of ICAM-1 and improve activity of SOD, and play an neuroprotective effect against middle cerebral artery occulusion.
