Objective To study the association of early prognosis and risk factors about early neurological deterioration (END) in aged patients with cerebral hemorrhage in basal ganglia. Methods One hundred and thirty-nine aged patients with cerebral hemorrhage in basal ganglia were selected. The patients were divided into END group (59 cases) and non-END group (80 cases), the clinical data were retrospectively analyzed. The patients were followed up 3 months after discharge, the prognosis was evaluated by modified Rankin scale. Logistic regression analysis was used to determine the independent risk factors of END. Results The incidence of END was 42.4%(59/139). The incidence of unfavourable prognosis in END group was significantly higher than that in non-END group:78.0%(46/59) vs. 30.0%(24/80), and there was statistical difference (P<0.05). The score of Canadian stroke scale (CSS) at admission in END group was significantly lower than that in non-END group: (5.2 ± 2.1) scores vs. (6.9 ± 1.7) scores, but the white blood cell count at admission, hematoma volume and brain ventricle hemorrhage rate were significantly higher than those in non-END group: (10.7 ± 2.9) × 109/L vs. (7.9 ± 2.4) × 109/L, (17.4 ± 14.9) ml vs. (11.2 ± 10.5) ml and 42.4%(25/59) vs. 18.8%(15/80), and there were statistical differences (P < 0.05). There were no statistical differences in sex, age, systolic blood pressure, diastolic blood pressure, body temperature, random blood glucose, fibrinogen, activated partial thromboplastin time, prothrombin time and the incidences of hypertension, smoking history, stroke, diabetes mellitus, hyperlipidemia between 2 groups (P>0.05). The Logistic regression analysis results showed that brain ventricle hemorrhage and white blood cell count at admission were independent risks factor for END in aged patients with cerebral hemorrhage in basal ganglia(P < 0.05 or < 0.01). Conclusions The aged patients with cerebral hemorrhage in basal ganglia will be prone to END, the brain ventricle hemorrhage and white blood cell count at admission are independent risks factor for END, and the early prognosis is poor.

Objective To investigate which subfamily genes of T cell receptor (TCR) V? expand predominantly during the course of experimental allergic neuritis (EAN). Methods Using RT-PCR and in situ hybridization techniques,the expression levels of TCR V? 2,6,8,10,14 in the peripheral blood,lymph nodes,peripheral nerves of group EAN and those of the control group were compared. Results In group EAN,the expression of TCR V? 6?8 mRNA increased at the early phage(41.1?1.1 and 74.4?1.9 vs 25.9?1.5 and 26.1?1.6) and became more significantly at the peak of the disease,and resolved to normal at the recovery phage in the lymph nodes.But they amounted up gradually from the early stage to the peak,and then decreased a little in the infiltrating T-lymphocytes in peripheral nerves,the difference was significant.In addition,the expression of TCR V? 8 was notably higher than that of TCR V? 6 in the levels of mRNA. Conclusion The subfamilies of TCRV? genes which restrict the development of EAN due to recognizing the specific antigens are TCRV? 8 and TCRV? 6. T lymphocytes specifically expressing TCR V?6?8 genes are activated and clonally proliferated in the lymph nodes,and then migrate to the involved peripheral nerves,which might induce a series of immune lesions consequently.
