Objective To compare the clinical value of fluid attenuated inversion recovery imaging (FLAIR),magnetic resonance diffusion-weighted imaging(DWI) and magnetic resonance angiography(MRA) in diagnosis of early cerebral infarction.Methods 70 cerebral infarction patients were chosen.They underwent FLAIR,DWI and MRA examination.Results 70 patients with early cerebral infarction mostly were multiple lessions accouting for 60％.Supper actue period had 22 cases and acute period had 48 cases.DWI had the highest detection rate of cerebral infarction,particularly in the hyperacute period the detection rate reached 100％,which was significantly higher than the FLAIR and MRA(x2 =12.4,P ＜ 0.05).Conclusion Especially in the early diagnosis of hyperacute cerebral infarction,DWI is superior to FLAIR and MRA.FLAIR showed better on the cortex and periventricular lesions,MRA can check out the blood vessel lesions in the infarction area.

Objective:To investigate the changes and clinical significances of serum levels of granulocyte macrophage colony-stimulating factor (GM-CSF),interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α) levels in patients with rheumatoid arthritis (RA).Methods:126 cases of patients with RA in our hospital from June 2013 to December 2016 were selected as RA group and divided into two subgroups as active RA group (69 cases) and remission RA group (57 cases) according to the severity of the disease.55 healthy cases who receive physical check in our hospital at same time were selected as the control group.The serum GM-CSF,IL-6 TNF-α levels were detected by enzyme linked immunosorbent assay (ELISA) and compared between different groups,the correlation of serum GM-CSF,IL-6 TNF-α levels with DAS28 were analyzed.Results:The serum GM-CSF,IL-6 TNF-α levels of RA group were significantly higher than those of the remission RA group and control group (P＜0.01),and the serum GM-CSF,IL-6 TNF-α levels of remission RA group were also significantly higher than those of the control group (P＜0.01).Positive correlation between serum GM-CSF,IL-6 and TNF-α levels were found(P＜.0.01).The level of DAS28 was significantly correlated with the levels of serum GM-CSF,IL-6 and TNF-α (r=0.473,0.584,0.675,all P＜0.01).Conclusion:The levels of serum GM-CSF,IL-6 and TNF-α were up-regulated in patients with RA and positively correlated with the activity of RA,which might be of important clinical significance in the early diagnosis,disease evaluation and prognosis of RA.

Objective To investigate the expression of phosphatidylinositol 3-kinase(PI-3K)in adipose tissue of polycystic ovary syndrome patients(PCOS),and explore molecular mechanisms of insulin resistance(IR)in PCOS.Methods Samples from patients with PCOS with IR(n=19),PCOS without IR (n=10)and controls(n=15)were collected.Serum fasting insulin(FIN)and fasting plasma glucose (FPG)were measure& Insulin resistance index was calculated using homeostasis model assessment (HOMA)to analyze the relationship between these markers and IR.Western blot technique was used to detect the PI-3K p85 subunit.Gene expression of PI-3K p85 subunit was detected by reverse transcription polymerase chain reaction(RT-PCR)method.Kinase activity was detected by immunoprecipitation,thin- layer chromatography and gamma scintillation counting.Results(1)The levels of FIN[(25.2?3.8) mU/L]and HOMA-IR(1.6?0.3)in PCOS with IR were significantly higher than those in PCOS without IR[(13.4 +3.8)mU/L,0.9?0.3]and controls[(9.5 +2.6)mU/L,0.5?0.3;all P＜0.05).(2) There was no significant difference in the protein(0.65?0.10)and gene expression(0.92?0.12)of PI-3 K p85 subunit in PCOS with IR compared with PCOS without IR(0.72?0.10,1.01?0.10)and control groups(0.73?0.14,1.00?0.12;P＞0.05).(3)PI-3K activity in PCOS with IR(81%)and PCOS without IR(89%)was significantly decreased(P＜0.01,P＜0.05)and negatively correlated with HOMA- IR(r=-0.69,P＜0.01;r=-0.62,P＜0.05).Conclusions No significant difference in the protein and gene expression of PI-3K p85 subunit in PCOS with IR is found.The decreased PI-3K activity may lead to IR of PCOS.

Based on previous results of 16S rDNA sequence homologuous and results of physic-biochemical indexes and morphological characteristics in the present work, bacterial strain ge15 isolated from roots of ginseng plants was identified as Stenotrophomonas rhizophila. Confronting incubation results showed that, strain ge15 inhibited the growth of Alternaria panax, Phytophthora cactorum, and Cylindrocapon destructans significantly, and the width of inhibition zone was 13.3, 24.0, 12.0 mm, respectively. Further results showed that the emergence rate and seedling survive rate of ge15 treatment was significantly higher than those of the control, and which was similar to pesticide carbendazol treatment. The ge15 strain has good application potential in ginseng diseases control without contamination.

ObjectiveTo explore the resilience and mental health of recruits during training,and to investigate mutual prediction of resilience between mental health and psychological stress to provide the scientific evidence for the mental health training and psychological selection of recruits.MethodsConnor-Davidson resilience questionnaire ( CD-RISC),symptom checklist ( SCL-90 ),psychological stress self-evaluation test ( PSET),satisfaction with life scale (SWLS),positive and negative affect scale (PANAS) were applied to 650 recruits in 2011 before starting training and after two months of training.Results ① Chinese recruits had good resilience,and the CD scores of pre-and post-test were (61.60 ± 14.36) and (61.41 ± 14.55 ) respectively.②Mental health (SCL-90) of two tests were good in recruits.③ Correlation analysis showed that the same premise of phase correlation,resilience (pre-test) could significantly predict mental health (post-test) ( β =0.070,P ＜ 0.05 ),mental health ( pretest) could not predict resilience (post-test) (β =0.015,P ＞ 0.05 ).Resilience (pre-test) could significantly predict psychological stress (post-test) ( β =0.075,P ＜ 0.05 ),psychological stress (pre-test) could not predict resilience (post-test) (β =0.017,P ＞ 0.05 ).④ Compared with high resilience group,low-resilience group of recruits had higher total score of SCL-90 and psychological stress and less positive emotion,more negative emotion and lower life satisfaction.ConclusionThe recruits training have good resilience.Resilience of recruits have predictive ability to mental health,psychological stress during training.
