Aim To investigate the regulatory effects of baicalin on apoptosis induced by virus H1 N1 in hu-man pulmonary carcinoma cell A549 . Methods The chips were used to screen the RNA samples in virus-in-fected A549 cells. Differentially expressed genes were selected in the pathway of apoptosis. The mRNA ex-pressions of caspase-3 and -8 were verified by Real-Time PCR. Results With the DNA microarray, the functions of differentially expressed genes involved in apoptosis biological pathways were analyzed by Kyoto Encyclopedia of Genes and Genomes ( KEGG ) Path-way databases. caspase-3, -7, -8, -10, TRAIL, MYD88 , IL1 A and IL1 B were up-regulated in virus-in-fected group. Oseltamivir could down-regulate gene ex-pressions of caspase-3 ,-4 and-8 . High-dose of baica-lin could down-regulate gene expressions of caspase-3 ,-4,-6 and -8. Except gene expressions of above, low-dose of baicalin could also down-regulate gene expres-sions of IL1RAP and Cn. Real-Time PCR experiments showed that baicalin could significantly decrease mR-NA expression of caspase-3 , -4 , -6 , -8 , IL1 RAP and Cn ( P < 0. 01 ) , compared with the virus-infected group. The results also figured that the interference ef-ficacy of low-dose baicalin was better than that of high-doses. As expected, real-time PCR data were in good agreement with the microarray assay. Conclusions Baicalin can be detected in their suppression effect of caspase-3,-4,-6, and -8 mRNA expression, so it re-sists against the apoptosis to fight against influenza vi-rus in vitro.

Objective There is little research focusing on the expression and function of bradykinin 1 receptor ( B1R ) and bradykinin 2 receptor ( B2R) after cerebral ischemia/reperfusion on the basis of diabetes .The aim of this study was to compare the ex-pression difference and function change of B 1R and B2R in non-dia-betic and diabetic rats . Methods The cerebral ischemia/reperfu-sion model was established on 41 non-diabetic and type 2 diabetic rats, the weight and the biochemical index were measured on these two types of rats .8 non-diabetic rats and 8 diabetic rats were respec-
tively assigned to two groups according to random number tables:control group and I/R 24 h group, 4 in each group.Real-time PCR was performed to observe the expressions of two receptors at 24 h after reperfusion .Then, 33 non-diabetic rats and 33 diabetic rats were randomly divided into 4 groups respectively, including sham group (n=6), saline group (n=9), B1R antagonist group (n=9) and B2R antagonist group (n=9).At 24 hours after cerebral I/R, neurological deficiency was evaluated by neurological severity scores ( NSS);infarct volume was observed by TTC staining;cell apoptosis was determined by TUNEL staining;neuron degeneration was de-tected by Fluoro-Jade C staining. Results Glucoses of diabetics at 3, 7, 14 d after model establishment [(23.45 ±5.01), (23.71 ±4.87), (22.72 ±4.11) mmol/L] were obviously elevated compared with non-diabetics [(5.77 ±0.75), (6.05 ±0.69), (7.15 ±1.09) mmol/L];blood cholesterin [(4.59 ±3.43) mmol/L] and insulin [(67.26 ±12.02) pmol/L] at 14 d after model establishment were evidently incresaed in comparison to those in non-diabetics [(1.58 ±0.37) mmol/L, (25.34 ±4.88) pmol/L] (P<0.05), while no significant difference was found in the blood triglyceride of diabetics between them (P>0.05).Compared with non-diabetics, diabetics suffered from more apparent up-regulation of B1R mRNA (P<0.01) but relatively less B2R mRNA (P<0.05) at 24 h after I/R.NSS score, infarction volume, damaged and apoptotic cells in B2R antagonis-treated non-diabetic rats at 24 h after I/R conspicuously decreased compared with saline-treated non-daibetic rats.Those indicators in B1R antagonis-treated diabeics were strikingly lessened compared with saline-treated daibetics . Conclusion I/R induced distinct up-regulation of B2R mRNA in non-diabetics and inhibiton of B 2R effectively ameliorated the infarct volume and cell injury after I/R in non-diabetics; I/R induced more notable up-regulation of B1R mRNA in diabetics and B1R antagonist exerted neuroprotective effects instead of B 2R antagonist af-ter I/R in diabetics.

Objective To study the relationships among resilience, self-awareness, personality, stress level and mental health in the warship soldiers. Methods Resilience Scale for Adults ( RSA), Eysenck Personality Questionnaire ( EPQ), Self Acceptance Questionnaire( SAQ), General Self-Efficacy Scale( GSES), Wallance Self Concept Scale (WSCS), Psychological Stress Self-evaluation Test (PSET) and Symptom Checklist (SCL-90)were used to survey 1451 warship soldiers. Results ① 2.5% of the warship soldiers reported obvious psychological stress. Mental health of warship soldiers was worse than the norm of China population, except for obsessivecompulsive and interpersonal sensitivity factor. While the scores of other factors were significantly higher than the norm of Chinese soldiers(P<0.01). ②The total scores of SCL-90, psychological stress and resilience, internal/external had negative correlation with self-awareness, and positive correlation with neuroticism. Compared to the SCL-90-negative group,SCL-90-positive soldiers (SCL-90 total score > 160) had higher scores of nervousness and PSET and lower scores of RSA, internal/external and self-awareness (P < 0.01 ). ③Regression analysis showed that stress levels, emotional stability,self-awareness and resilience were able to predict 35.1% of mental health in warship soldiers. Mental health, emotional stability, internal/external and resilience were able to predict 33.2%of individual's stress level. Conclusion To some extent, warship soldiers have psychological stress and mental health problems. Resilience, personality, self-awareness are important factors affecting psychological stress and mental health.
