AIM:To investigate the role of SDF-1? in migrating of bone marrow stromal cells to the injured areas. METHODS:Ischemic brain lesion model was created in rats by permanent middle cerebral artery occlusion (MCAO). 48 SD rats were divided randomly into 2 groups. Group 1:phosphate buffered saline (PBS 1 mL) for control (n=25); Group 2:BMSCs (2?106) were injected intravenously at 24 h after MCAO (n=24). After propagated in BMSCs,Ad5/F35 GFP (green fluorescent protein) was infected to BMSCs. The expression of SDF-1? (stromal cell-derived factor-1?) mRNA in the penrumbral tissue was assayed by real-time quantitative PCR. The expression of CXCR4 on MSCs was detected by flow cytometry. Confocal microscopy was used to detect the GFP-labeled MSCs migration. RESULTS:Ad5/F35 GFP signals was observed in almost infected BMSCs. The expressions of SDF-1? mRNA in the thalamus and hippocampus of the ischemic brains were peaked at 3rd day after stroke,followed by a decrease at 14th day post-ischemia. The expression of SDF-1? mRNA in the cortex of the ischemic brains was peaked at 7th day post-ischemia,still at high level at 14th day post-ischemia. The median percentage of surface CXCR4 expression in BMSCs was 14%. GFP labeled BMSCs were detected in the origination of the middle cerebral artery (olfactory area) at 6 h,after 3 days in the prenumbra tissue such as thalamus,and in the cortex more labeled cells were found after 14 d post-ischemia.CONCLUSION:BMSCs can pass through the blood brain barrier of ischemic rats. Its mechanism might be associated with the expression of SDF-1? in the ischemic brain.

Objective: To investigate association between psychosocial factors and anxious and depressive disorders in patients with diabetes mellitus. Methods: 172 patients with type 2 diabetes were inquired with a self-administered questionnaire about their socio-demographic characteristics, perceived stress caused by the disease, coping styles, social support. At the same time, anxious and depressive disorders were assessed with HAD.Results:Among our sample, 35 (20.3%) patients with anxiety, 33 (19.2%) with depression. After adjusting for gender, age, marital status, educational level and income, multivariate logistic regression analysis found the following results. Perceived stress from "Worrying about to be harmed by the disease"(OR=1.76,95%CI 1.12~2.77),"Social/family crisis caused by the disease"(OR=1.85, 95%CI 1.18~2.92),"Worrying about declining in body/physical function"(OR=2.16, 95%CI 1.28~3.67), "Declined economic condition"(OR=2.03,95%CI 1.27~3.26)and "Negative coping styles"(OR=1.94,95%CI 1.26~2.97)were significantly associated with anxious disorders. The perceived stress from "Social/family crisis caused by disease"(OR=1.79, 95%CI 1.09~2.96), "Worrying about declining in body/physical function"(OR=2.89, 95%CI 1.59~5.24)and "Negative coping styles"(OR=1.95,95%CI 1.23~3.11)were significantly associated with depressive disorders, while patients "Taking avoidant measures"(OR=0.52, 95%CI 0.30~0.90)were less depressive disorders.Conclusion: Anxious and depressive disorders in patients with 2 type diabetes were significantly associated with patients' perceived stress from the disease and their coping styles.

Objective To test the in vitro effect of the extract of Herba taraxaci on Demodex folliculorum. Methods Active Demodex folliculorum were obtained from patients with moderate to severe demodex infestation. Herba taraxaci and Radix stemonae were extracted respectively with 80% ethanol under 85℃, and a preparation with a concentration of 200mg/ml was made. The extractions were used in vitro to examine the anti-mite activity by observing time of killing mites. Physiological saline and Radix stemonae extraction served as blank control and positive control respectively. PH value of Herba Taraxaci extract was noted. Skin irritation test of normal and wounded skin and acute toxicity test were carried out with rabbit shin, and Herba taraxaci and 75% ethanol were served as experiment and control medicine. Results Motion and morphology of the mites considerably changed with the effect of Herba taraxaci extract. The time of mite-killing was (1.50?0.65)min with Herba taraxaci and (3.53?1.04)min with Radix stemonae respectively (P

(0.05)). Multivariate analysis revealed that adjuvant radiotherapy and histology of tumor significantly affected the prognosis(P=(0.045) and P=(0.009), respectively). Whereas loco-regional control was only significantly affected by adjuvant radiotherapy(P=(0.000)). CONCLUSION: Adjuvant radiotherapy and histology of tumor are the important prognostic factors in the rectal cancer patients after treatment with multimodality therapy based on surgery.

Objective To guide the therapy for cyanide poisoning patients on plateau, the effect of hypoxia on the efficiency of 4-(N, N-dimethyl)-aminophenol (4-DMAP) in ferrihemoglobin (MHb) formation was investigated. Methods Rabbits were raised in hypoxic condition (4500m altitude) as acute-hypoxic animal model, and MHb concentration was determined by spectrophotography at the length of 635nm after 4-DMAP injection. Results There was no difference in hemoglobin content and MHb concentration between acute acutehypoxia group and controls. But in hypoxic rabbits, MHb formation as induced by 4-DMAP was improved distinctly. 30%-40% MHb concentration formation (optimal anti-cyanide concentration) was induced by 20mg/kg 4-DMAP in hypoxic rabbits, compared to 25-30mg/kg in control rabbits. However, when hypoxic rabbits received 25-30mg/kg 4-DMAP, which was the optimal dose for treatment of cyanide poisoning in normoxic animals, the animals manifested even worse symptoms of hypoxia, eren death occurred. Moreover, the level of MHb in acute-hypoxic models maintained longer than that in controls. The effect of 4-DMAP in MHb formation was closely related with duration of hypoxia. During hypoxia period from 1d to 5d, MHb concentration was increased gradually along with the duration of hypoxia, peaking on the 5d, and it started to decline on 7d, but it was still higher than that in control group. Conclusion Hypoxia enhances the effect of 4-DMAP in MHb formation and lowers the metabolism of MHb.
