ABSTRACT
We typed Yersinia pestis isolated from plague foci of Shaanxi Province using different region (DFR) and analyzed epidemiological characteristics.Twenty-three DFRs primers and PMT1 (plasmid) primer were used to verify the DFR genomovars and 48 Yersinia pestis were involved to analyze DFR profiles and epidemiological characteristics.In the same year,the genotypes of Yersinia pestis isolated from different infected vector and animals were basically the same.Three genomovars named Genomovar 11,17,and 20 were verified in 48 Yersinia pestis strains in Shaanxi Province.The main genotypes were different in different epidemic years.In 1987-1988 and 2000-2001 years,genomovar 17 was major genomovar and genomovar 20 in 2006 year.In conclusion,the dominant genotypes were different in different epidemic years.As time goes on,DFR genomovars of Yersinia pestis undergone the evolution of gene deletion,which changes genomovar 17 into genomovar 20.
ABSTRACT
Objective To observe the changes in microRNA (miRNA) expression levels in peripheral blood of schizophrenia patients before and after treatment with antipsychotics. Methods Sixty-one consecutive patients with schizophrenia (case group) and 62 normal controls (control group) hospitalized to the 102nd Hospital of PLA from July 2012 to May 2013 were involved in this study. The relative expression levels of 9 miRNAs (miR-181b, miR-195, miR-132, miR-212, miR-30e, miR-346, miR-34a, miR-432, miR-7) in the peripheral blood plasma of patients in two groups were determined by real-time fluorescence quantitative PCR. Twenty-five schizophrenia patients with total score of Positive and Negative Syndrome Scale (PANSS) >70 were selected to determine the miRNA expression levels before and 3 and 6 weeks after antipsychotics (including olanzapine, quetiapine, ziprasidone and risperidone) treatment, and the clinical symptoms and treatment effect in different stages of therapy were assessed by PANSS, Global Assessment Scale (GAS), and Clinical Global Impression scale (CGI). Results The expression levels of miR-181b, miR-30e, miR-346, miR-34a and miR-7 in case group were significantly higher than those in control group (P70, the expression level of miR-132 lowered 3 weeks after treatment (P0.05). The expression of miR-132, miR-195, miR-30e and miR-432 were significantly correlated with the PANSS total score and GAS score along with the treatment course (P<0.05). Conclusion The miR-181b, miR-132, miR-30e and miR-432 maybe used as biological markers for the prediction of the prognosis of patients with schizophrenia.
ABSTRACT
<p><b>OBJECTIVE</b>This study aimed to explore the scene-trait coping style of military rescuers in Wenchuan earthquake in an effort to provide scientific evidences for mental intervention program for Chinese military personnel.</p><p><b>METHODS</b>By cluster sampling, a total of 151 military rescuers and 331 control servicemen were administered the military personnel scene-trait coping style scale (MPSTCSS).</p><p><b>RESULTS</b>All active coping factor scores, and passive coping factor scores of affection, health and economy in the rescuer group were significantly higher than those in control group (P < 0.05). The 21-above age subgroup, the 3-year plus service subgroup, and the officer subgroup had significantly higher active coping factor scores on military tasks, military experience and personal development than those of the 21-below age subgroup, 3-year minus service subgroup and the soldier subgroup, respectively (P < 0.05 or P < 0.01).</p><p><b>CONCLUSION</b>The earthquake relief servicemen can cope with stressful situations better than control group by taking active coping style. The officers, servicemen older than 21 years, and servicemen with more service duration than 3 years could usually take active coping style.</p>
