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 study the optimum parameters of the supercritical CO2 fluid extraction of Polyrhachis vicina Roger and chemical constituents of ant oil. Methods The experiments were designed with the uniform design. Three factors are extraction pressure, temperature and time. GC-MS was applied for analyzising. Results The optimum condition was obtained:the extraction pressure is 36 MPa, the temperature of extraction is 40 ℃ and extraction time is 50min. 45 components were identified from 60 chromatographic peaks.

Objective:To study the effects of glucose,mannose and galactose on CAP10 promoter activity of Cryptococcus neoformans capsule-associated gene.Methods: Yeast cells were transfected with plasmid containing a 951 bp length of 5′ upstream flanking sequence of CAP10 coding region and a reporter gene,chloramphenicol acetyl transferase(CAT);the transfectants were treated with different concentrations(10,20,40,60,80 mg/ml) of glucose,mannose and galactose.CAT activity was assessed by ELISA method and CAT activities of different groups were compared.Results: Different concentrations of glucose and mannose had no obvious influence on CAT activity;different concentrations of galactose had obvious influence on CAT activity and the influence was positively dependent with its dose within the experimental concentration range.Conclusion: Glucose and mannose have no obvious effect on the activity of CAP10 promoter;galactose has obvious inductive effect on activity of CAP10 promoter,suggesting that CAP10 gene might be related with galactose metabolism.

Crocetin, a naturally occurring carotenoid, possesses antioxidant and antiatherosclerotic properties, of which the underlying mechanism remains unclear. In the present study, we examined the effects of crocetin (0.1, 1, 10 μmol·L(-1)) on angiotensin II (Ang II, 0.1 μmol·L(-1)) induced expression of vascular cell adhesion molecule-1 (VCAM-1) in human umbilical vein endothelial cells (HUVECs) and monocyte-endothelial cell adhesion. The effects of crocetin on the activation of nuclear factor kappa B (NF-κB) and intracellular reactive oxygen species (ROS) were also observed. The results demonstrated that crocetin notably suppressed Ang II induced NF-κB activation (P<0.01) and VCAM-1 expression (P<0.05, P<0.01) in HUVECs, accompanied by a markedly reduced monocyte-endothelial cell adhesion (P<0.05, P<0.01). In addition, preincubation with crocetin resulted in a significant enhancement of cellular antioxidant capacity (P<0.05, P<0.01), while Ang II induced intracellular ROS decreased markedly (P<0.05, P<0.01). These results indicated that crocetin was capable of suppressing Ang II induced VCAM-1 expression and monocyte-endothelial cell adhesion by suppression of NF-κB activation, which might be derived from the enhancement of antioxidant capacity and subsequent reduction of intracellular ROS.

BACKGROUND:The early damaged chondrocytes are susceptible to de-differentiate and exert unstable phenotype during the in vitro culture, thus needing some growth factors.
OBJECTIVE:To observe the promotion effect of insulin-like growth factor 1 on the in vitro proliferation of chondrocytes in adult rabbits with traumatic arthritis.
METHODS:Traumatic arthritis models of adult rabbits were established by using the modified Hulth method. After the models were successful y established, the distal femur and proximal tibia were harvested under sterile conditions, the chondrocytes were cultured. The cultured cells were divided into two groups:control group was cultured with Dulbecco’s modified Eagle’s medium containing 10%fetal bovine serum, while experimental group was cultured with Dulbecco's modified Eagle’s medium containing 100μg/L insulin-like growth factor 1. The effect of insulin-like growth factor 1 on the proliferation of chondrocytes in adult rabbits with traumatic arthritis was determined through the cytomorphology, cellcounting, and cellactivity.
RESULTS AND CONCLUSION:The chondrocytes in adult rabbits with traumatic arthritis were successful y cultured, the majority of cells were mini-cells, presenting smal fusiform, round or polygonal shape. Hematoxylin-eosin staining showed that the number of cells in experimental group was higher than that in control group. MTT assay found that the absorbance of cells in experimental group was greater than that in control group (P<0.01). Our findings indicate that, insulin-like growth factor 1 can promote the in vitro proliferation of chondrocytes in adult rabbits with traumatic arthritis.
