Objective To investigate the major risk factors for posterior circulation stroke and the clinical and imaging features of posterior circulation stroke patients with diabetes.Methods The patients with acute cerebral infarction were enrolled.The clinical data of patients with posterior circulation and anterior circulation stroke were compared.The patients with posterior circulation stroke were further divided into either a diabetic group or a non-diabetic group,and the vascular risk factors and imaging features of both groups were compared.The patients with posterior circulation stroke were divided into proximal segment,middle segment and distal segment and mixed groups according to the distribution of vascular lesions.The correlations between diabetes and each group and the imaging features were analyzed.Results A total of 328 patients with posterior circulation stroke (male 194,the diabetic group 108) and 336 patients with anterior circulation stroke (male 214,the diabetes group 59)were enrolled.The proportions of patients with diabetes (32.9％ vs.21.7％ ; x2 =10.501,P =0.001),hyperlipidemia (60.1％ vs.47.9％ ;x2 =9.852,P =0.002),previous stroke or transient ischemic attack (TIA) (29.0％ vs.22.0％ ;x2 =4.213,P =0.040) in the posterior circulation ischemic stroke group were significantly higher than those in the anterior circulation ischemic stroke group,and the proportion of smoking patients was significantly lower than that in the anterior circulation ischemic stroke group (18.3％ vs.26.2％ ; x2 =5.977,P =0.014).The levels of total cholesterol (4.72 ±1.07 mmol/L vs.4.56 ± 0.98 mmol/L; t =2.079,P =0.038),triglycerides (1.54 ± 1.07 mmol/L vs.1.33±0.71 mmol/L; t=3.085,P=0.002) and low-density lipoprotein cholesterol (2.91±0.90 mmol/L vs.2.75 ±0.80 mmol/L; t =2.373,P =0.018) were significantly higher than those in the anterior circulation ischemic stroke group,and the level of high-density lipoprotein cholesterol was significantly lower than that in the anterior circulation ischemic stroke group (1.13 ± 0.31 mmol/L vs.1.18 ±0.32 mmol/L; t =2.045,P=0.041).Multivariate logistic regression analysis showed that diabetes (odds ratio [OR] 1.560,95％ confidence interval [CI] 1.086-2.239; P =0.016) and previous stroke or TIA history (OR 1.455,95％ CI 1.013-2.090; P =0.042) were the independent risk factors for posterior circulation ischemic stroke.In patients with posterior circulation ischemic stroke,the patient's proportions of hyperllpidemia (66.7％ vs.55.5％ ;x2 =5.069,P =0.024) and drinking (13.0％ vs.4.5％;x2 =7.568,P=0.006) in the diabetic group (n =108) were significantly higher than those in the non-diabetic group (n =220); the proportion of atrial fibrillation patients was significantly lower than that in the non-diabetic group (3.7％ vs.11.4％ ;x2 =5.274,P =0.022).The levels of triglycerides (1.70 ± 0.93 rnmol/L vs.1.45 ± 1.11 mmol/L; t =1.989,P =0.048),fasting glucose (8.46 ± 2.96) mmol/L vs.5.30± 0.96 mmol/L; t=10.706,P=0.000) and glycosylated hemoglobin (8.36％ ± 1.94％ vs.6.07％ ± 0.55％ ; t =10.576,P =0.000) in the diabetic group were significantly higher than those in the non-diabetic group.The proportion of patients with large artery atherosclerosis stroke in the diabetic group was significantly higher than that in the non-diabetic group (73.1％ vs.60.0％; x2=5.457,P=0.019); the proportion of the patients with cardioembolism was significantly lower than that of the non-diabetic group (2.8％ vs.9.1％;x2 =4.428,P =0.035).The proportion of patients with posterior circulation middle segment infarction in the diabetic group was significantly higher than that of the non-diabetic group (49.1％ vs.31.4％ ;x2 =9.726,P =0.002).The proportions of the patients with brainstem infarction (60.2％ vs.48.2％ ;x2 =4.182,P =0.041) and single brainstem infarction (55.6％ vs.30.5％ ;x2 =19.235,P =0.000) in the diabetic group were significantly higher than those in the non-diabetic group.In patients with single brainstem infarction,the proportions of the patients with pontine infarction (43.5％ vs.25.9％ ;x2 =10.374,P =0.001) and medulla oblongata infarction (7.4％ vs.1.8％ ; P =0.023) in the diabetic group were significantly higher than those in the non-diabetic group.Conclusions Diabetes and previous stroke or TIA history are the independent risk factor for posterior circulation stroke.Diabetes is closely associated with brainstem infarction,and it is more likely to result in pontine infarction.

Objective To investigate the features of immune response of human immunodeficiency virus type-1 (HIV-1) antigen specific T lymphocytes in HIV-1 monoinfected or HIV 1/hepatitis C virus (HCV) coinfected individuals.Methods Twenty-six HIV-1 monoinfected and 23 HIV-1/HCV coinfected individuals were enrolled.Immunomagnetic microbeads were used to isolate T lymphocyte subpopulation CD4+ T cells and CD8+ T cells from human peripheral blood mononuclear cells (PBMC).Frequencies of interferon-γ (IFN-γ) secreting cells of CD4+,CD8+ T lymphocytes and PBMC stimulated by a peptide pool containing 12 overlapping peptides in HIV-1 P24 from 49 patients were assessed by enzyme-linked immunospot (ELISPOT) assay.HIV-1 RNA levels of these patients were also detected by real-time fluorescence quantitative polymerase chain reaction.The data were compared by one-way ANOVA and Mann-Whitney U test,and Spearman test was used for correlation analysis.Results Frequencies of HIV-1 antigen specific CD4+ T lymphocytes [median =25 spot-forming cells (SFC)/106 cells] were significantly lower than those of CD8+T lymphocytes (median=38SFC/106 cells,F=4.592,P=0.037) and PBMC (median=53 SFC/106 cells,F=5.436,P=0.025) in HIV-1 monoinfected group.Frequencies of HIV-1 antigen specific CD4+ T lymphocytes (median=5 SFC/106 cells,Z=-2.432,P=0.015),CD8+T lymphocytes (median=5 SFC/106 cells,Z=-1.996,P=0.046) and PBMC (median=10 SFC/106 cells,Z=-2.306,P=0.021) in HIV-1/HCV coinfected group were significantly lower than those in HIV-1 monoinfected group.Conclusions In HIV-1 infection,antigen specific immune response of CD4+ T cells can be activated,but weaker than that of CD8+ T cells.Co-infection with HCV might down-regulate the responses of HIV-1 antigen specific T lymphocytes in HIV-1 infected individuals.

Objective; To study estrogen receptor gene Xbal and Pvu Ⅱ polymorphisms in patients with aggressive periodontitis (AgP). Methods; Xbal and Pvu Ⅱ DNA was extracted by Chelex-100 and amplified by PCR from buccal swabs of 48 cases of AgP patients and 60 normal controls. The PCR products were analyzed by polymerase chain reaction linked fragment length polymorphism (PCR-RFLP) assay. Results: There were significant differences of the distribution of Xba I genotype between AgP group and control group, female AgP group and female control group, male AgP group and male control group(P<0.05). There was no difference of Pvu D genotype distribution between patient group and control group (P>0.05). Multivariate Logistic Regression Analysis showed that male group was less susceptible to AgP than female group(OR =0. 352), the older was less susceptible to AgP than the younger(OR =0.950), and the xxXx genotype was less susceptible to AgP than XX genotype [OR(Xx) =0.224, OR(xx) = 0.678). Conclusion: Specific relationship is found between the susceptibility of AgP and the ER gene-Xbal polymorphism. People with XX genotype is more susceptive to AgP than xx, Xx genotypes.

OBJECTIVETo explore the effect of internal fixation with screw through femoral epiphyseal plate on growth in- hibition via an experimental study.

METHODSForty New Zealand rabbits were randomly divided into 4 groups and 10 rabbits in each group. Epiphyseal plate was injured by penetrating of screws, and the size of damage area was controlled by changing the number of threads. Group A: blank group; group B: injury area accounted for 4% of the epiphyseal plate; group C: injury area accounted for 6%; group D: injury area accounted for 8%. The internal fixation was removed after 2 weeks, and the results were observed with X-ray film for 4 groups to judge the complications such as early closure of epiphyseal.

RESULTSIn each group, there were no statistical differences in the length of the femoral neck, the diameter of femoral neck, the diameter of the femoral head, and the epiphyseal plate closure time. The growth speed of the length and diameter of the femoral neck, as well as the diameter of femoral head, were quicker on the early phase, and the speed was slowest when the epiphyseal plate was being closed.

CONCLUSIONThe injury area of epiphyseal plate under 8% is safe for its growth. Because no evidences demonstrate the growth inhibition of epiphyseal plate, the screws can be used for rabbit epiphyseal plates.
