The brain-gut axis is an important pathway for the interaction between the central nervous system and the gastrointestinal tract. Ischemic stroke can promote the imbalance and displacement of intestinal flora, and the intestinal flora and its metabolites in turn can affect the occurrence, development and outcome of ischemic stroke. This article reviews the related literature on ischemic stroke and intestinal flora, in order to review the relationship between the two and related mechanisms, and to prospect the stroke treatment of targeting intestinal flora.

OBJECTIVE:To optimize the formulation of Methotrexate thermosensitive hydrogels,and to study the in vitro re-lease property of it. METHODS:Taking PLGA-PEG-PLGA as matrix and mannitol as viscosity modifiers,Methotrexate thermosen-sitive hydrogels were prepared. Using the absolute value of the deviation of gelation temperature between 35 ℃,its formulation was optimized by orthogonal test using the concentrations of PLGA-PEG-PLGA,methotrexate and mannitol as factors. The dialysis bag method was used to investigate accumulative release rate of Methotrexate thermosensitive hydrogels and methotrexate solution within 336 h in vitro. RESULTS:The optimal formulation was as PLGA-PEG-PLGA of 20%,methotrexate of 0.10% and mannitol of 0.10%;gelation temperature were 35.1,35.0,35.0℃. The average drug-loading rate was more than 90%. 12 d accumulative re-lease rate was more than 90%(r=3). Methotrexate solution has been substantially completely relased within 240 h. CONCLU-SIONS:Methotrexate thermosensitive hydrogels with sustained-release are prepared successfully,and the preparation technology is simple and practical.

Objective Sarcopenia and metabolic syndrome share similar pathophysiological mechanisms. The aim of this study was to investigate the prevalence of sarcopenia among health examination population, and to analyze the relationship between sar-copenia and blood pressure, blood glucose, uric acid and lipids. Methods Physical examination data of 1191 healthy persons in the medical examination center of the hospital from Mar 2011 to Jun 2011 were collected. The weight, skeletal muscle, body fat, body mass index ( BMI) , waist circumference,body fat percentage, waist-hip ratio and visceral fat area were analyzed by human body compositionanalyzer and the prevalence of sarcopenia was observed. At the same time, triglyceride (TG), total cholesterol (TC), high density lipo-protein-cholesterol ( HDL-C ) , low density lipoprotein-cholesterol ( LDL-C) , uric acid and fasting blood glucose were also detected. Results The prevalence rate of sarcopenia of the subjects was 5.21%, and the highest incidence was found in ≥60 years group( 11.11%) . The prevalence rates of overweight and obesity were 33.8% and 10.2%, respectively. The prevalence of sarcopenia is grad-ually higher along with increasing BMI. The prevalence rates of sarcopenia of overweight and obesity subjects were 5.47% and 26.23%, respectively. Compared with the normal control group, the level of weight[(66.34±11.75)kg vs (76.71±12.84)kg ], BMI[(23.37± 3.13) vs (28.05±3.66)], body fat percentage[(25.33±6.06)% vs (36.76±4.47)%], waist circumference[(83.19±9.56)cm vs (95.45±13.74)cm] and visceral fat area[(88.96±29.74)cm2 vs (136.91±25.56)cm2] were higher in the sarcopenia group (P<0.05). Compared with the normal control group, the incidence of systolic blood pressure[(125.59±30.04)mmHg vs (139.39±19.79) mmHg], diastolic blood pressure[(75.82±11.95)mmHg vs (82.34±10.96)mmHg ] TG[(1.56±1.12)mmol/L vs (1.98±1.72)mmol/L] and uric acid[(313.75±83.07)mmol/L vs (335.55±96.07)mmol/L] were higher in the sarcopenia group (P<0.05). Compared with the normal subjects, the detectable rates of abnormal diastolic blood pressure, fasting blood glucose, uric acid, and LDL-C were increased in the sarcopenia, obesity and sarcopenia combined with obesity subjects (P<0.05). The odds ratio of abnormal systolic blood pressure, diastolic blood pressure, uric acid, and LDL-C increased in the sarcopenia, obesity and sarcopenia combined with obe-sity subjects using logistic regression analyses after correction of gender and age. Conclusion The sarcopenia may have some con-nection with metabolic risk factors. Early detection of sarcopenia can help to distinguish people predisposed to metabolic syndrome, and it has important significance for prevention of chronic disease.

Objective To explore the relationship between resilience and personality among the physically disabled people.Methods A total of 668 disabled persons were tested by Connor-Davidson Resilience Scale(CD-RISC), Eysenck Personality Questionnaire Short Scale (EPQ-RSC), Rosenberg Self-Esteem Scale (SES).Results The score of resilience of disabled people(53.42± 18.18) was than lower Chinese community people (65.4 ± 13.9, t =-16.83, P＜ 0.05).The scores of the three sub-factors were tenacity (27.19 ± 10.23), strength (18.11 ±6.42) ,optimism(8.09±3.00).The disabled persons' resilience was positively correlated with self-esteem(r=0.52,P＜0.01) ,extraversion(r=0.47, P＜0.01) ,and negatively correlated with psychoticism(r=-0.34, P＜0.01), neuroticism(r=-0.32, P＜0.01).Self-esteem and extraversion could make positive predictions,while psychoticism and neuroticism could make negative predictions to the resilience of disabled persons.Conclusion The disabled Persons' personality is closely related with resilience and has significant predictions to resilience.

Objective:To investigate the radiosensitizing effect of three flavonoids on ovarian cancer SKOV3 cells under hypoxia. Methods:The SKOV3 cells were divided into normoxic group and hypoxic group. The hypoxic SKOV3 cellular model in vitro was es-tablished and tested by measuring the expression profile of HIF-1αprotein in SKOV3 cells. Colony-forming assay was used to detect the radiosensitivity of normoxic and hypoxic SKOV3 cells. The cytotoxicity and radiosensitizing effects of flavonoids were evaluated on the basis of cell death and MTT assay. Results:The Western blot results showed that the gray intensity ratio of HIF-1α/β-Actin in hypoxia group was significantly higher than that in normoxia group (1. 068>0. 117). Radiosensitivity of hypoxic SKOV3 cells in hypoxia group was significantly lower than that in normoxia group. The survival rate of SKOV3 cells was decreased with the increase of concentration. When the concentration was increased, D0 and Dqin chrysin group and quercetin group were significantly decreased (P<0. 01), and SER was increased (P<0. 05). SER showed no significant difference in breviscapine group (P>0. 05). The overall radiobiological parameters of hypoxia group were higher than those of normoxia group. Conclusion: Hypoxia can induce the expression of HIF-1α in SKOV3 cells, which results in the decrease of radiosensitivity. Chrysin and quercetin can enhance the radiosensitivity of SKOV3 cells, and the enhancement is significant under hypoxia, while breviscapine is without such effect. The radiosensitizing effect may be achieved by the level decrease of HIF-1α in SKOV3 cells and inhibition of DNA damage repair.
