Objective To investigate the relationship between the disorder of learning and memory in lead rats and the argnine vasopressin (AVP) and the somatotatin (SS) of hippocampus.Methods Sixty healthy 2-month old Sprague-Dawley rats were randomly divided into normal control group and lead group. Normal control group was given deionized water and the lead group was given 0.1% lead acetate deionized water for 3 months to make chronic lead rat. Learning and memory ability was tested by the Y-maze test. The content of AVP and SS in hippocampus were tested by the immunohistochemical method. Results The learning memory ability and the content of AVP and SS in hippocampus CA1 section of the lead group were degraded obviously than the control group(all P0.05)in hippocampus CA3 section of the lead group were degraded also.Conclusion The disorder of the learning and memory of the lead exposure rats may be due to the decrease of the content of AVP and SS in hippocampus.

Class Ⅱa bacteriocins can be considered as the major subgroup of bacteriocins from lactic acid bacteria, not only because of their large number, but also because of their activities and potential applications. They have first attracted particular attention as listericidal compounds and are now believed to be the next in line if more bacteriocins are to be approved in the future. The present review attempts to provide an insight into general knowledge available for class Ⅱa bacteriocins and discuss common features and recent findings concerning these substances.

Objective To explore the safety and clinical efficacy of Ginkgo biloba lactone injection combined with Alteplase intravenous thrombolysis in treatment of acute ischemic stroke.Methods Totally 87 patients were recruited and divided into control group and test group.The,patients in control group (39 cases) were given Alteplase 0.9 mg/kg for injection,intravenous bolus total dose 10％ was given within 1 min,then intravenous infusion of the remaining 90％ was given in 1 h,and given basic therapy after 24 h.The 48 cases in test group,which were immediately iv Ginkgo biloba lactone injection after intravenous thrombolysis,6 mL added into 250 mL saline,once daily for 14 d,and also were given basic therapy after 24 h.All NIHSS scores were recorded before treatment,14 d and 90 d after treatment,and the adverse events were recorded.The modified Rankin scale (mRS) score and BI index were performed at 14 and 90 d after admission.Patients in two groups were classified according to the TOAST classification,and the patients with large-arteryatherosclerosis and small-artery occlusion were analyzed.Results No intracranial hemorrhage occurred in the two groups.The NIHSS score and mRS score of test group were significantly lower than that of control group,and BI index was significantly increased 90 d after treatment.The NIHSS score and mRS score of test group were significantly lower than that of control group,and BI index was significantly increased90 d after treatment of patients with large-artery atherosclerosis.But there was no significant difference between test group and control group of patients with small-artery occlusion.Conclusion Ginkgo biloba lactone injection combined with rt-PA intravenous thrombolysis in the treatment of acute ischemic stroke has high safety,and can improve the prognosis of patients.

Objective: To study the effect of berberine (BR) on ventricular remodeling in experimental rats with myocardial infarction (MI) and its mechanisms.
Methods: The MI model of experimental rats was established by ligation of the left anterior descending coronary artery and the MI animals were randomly divided into 3 groups: MI+BR group, in which the rats received BR 20 mg/kg.d, Sham group and MI group, the rats in those 2 groups received the same volume of normal saline. All animals were treated for 8 weeks. The cardiac function and structure were assessed by echocardiography, cardiac interstitial collagen deposition was evaluated by Masson stain, the myocardial cell apoptosis was detected by Tunel method, and the activation of nuclear factor (NF-κB) was also examined.
Results: For echocardiography, MI group had enlarged left ventricular end diastolic diameter (7.28 ± 0.29) mm than Sham group (6.86 ± 0.36) mm,P<0.05, but it decreased in MI+BR group (6.89 ± 0.99) mm,P>0.05. MI group had increased left ventricular end systolic diameter (5.88 ± 0.33) mm than Sham group (4.61 ± 0.31) mm, but it decreased in MI+BR group (4.68 ± 1.17) mm, allP< 0.01. MI group showed increased left ventricular posterior wall compensatory hypertrophy (1.81 ± 0.85) mm than Sham group (1.67 ± 0.16 mm),P<0.05, while in MI+BR group, it was deereased to (1.65 ± 0.14) mm. MI group presented decreased LVEF (45.77 ± 3.17) % than Sham group (67.28 ± 4.15) %, but it increased in MI+BR group (64.64 ± 5.82) %, allP<0.01. For Masson stain, cardiac interstitial collagen deposition in MI group (11.39 ± 0.45) % was higher than Sham group (2.65 ± 0.45) %, but less in MI+BR group (7.00 ± 0.87) %, allP<0.01. For Tunel examination, the myocardial cell apoptosis index was increased in MI group (21.31 ± 2.34) than Sham group (0.99 ± 0.38), but decreased in MI+BR group (14.15 ± 1.62), allP<0.01. For NF-κB activation study, the nuclear protein p65 content was higher in MI group (0.14 ± 0.02) ng/ml than Sham group (0.06 ± 0.01) ng/ml, but lower in MI+BR group (0.10 ± 0.02) ng/ml, allP<0.01.
Conclusion: Application of BR may improve the ventricular remodeling and cardiac function in experimental MI rats, it might be because of BR partially inhibit NF-κB activation, reduce collagen deposition and help anti-apoptosis in myocardial cells.

Objective To explore the value of diffusion tensor imaging (DTI) and diffusion tensor tracography (DTT) in assessment of Corticospinal tract (CST) and medial lemniscus (ML) in tumors involving brainstem.Methods A total of 35 cases with pathologically confirmed tumors involving brainstem were collected,and 35 volunteers matched with genders and ages were recruited as the normal group.DTI scanning was performed on all the patients and controls.The damage degrees of CST and ML were evaluated and graded by DTT,and the dysfunction degrees were evaluated for the patients.Spearman correlation was used to statistically analyze the relationships of limb movement,sensory dysfunction and CST and ML damage.Results According to the rating results,normal findings,shifting,edema or infiltration and damage of CST was found in 9,9,11,and 6 cases respectively.They were 8,9,15,3 cases for ML.Motor function was normal in 20 cases,slightly defective in 11 cases,and moderate defective in 4 cases.Sensory function was normal in 21 cases,slightly defective in 6 cases,and moderate defective in 8 cases.The patients' dyskinesia and CST damage degree,sensory dysfunction and ML damage degree were positively correlated (r was 0.786 and 0.686 respectively,P ＜ 0.01).The position relationship among tumor and CST and ML could be well displayed on images.None of the patients showed new symptoms of dysneuria after surgery.Conclusions DTI and DTT technology can be used to evaluate CST and ML damage degree in tumors involving brainstem.They can display the position relationship between tumor and the brainstem CST and ML,which is important in protecting the brainstem fiber tract during operation and evaluating the recovery after the operation.
