RESUMO
OBJECTIVE@#To study the effects of prenatal cold stress on the behavior and mood of offspring in pregnant rats.@*METHODS@#Six SPF-class Wister pregnant rats were randomly divided into normal temperature control group and cold stress group with 3 rats in each group. The pregnant female rats in the normal temperature control group were kept in the environment of (22 ±2)℃, and the pregnant female rats in the cold stress group were placed in the artificial intelligence climate chamber at(4 ±0.1)℃ for 7 days before the birth, and the young rats were divided into normal temperature after the young rats were born. After the young rats were born, they were divided into normal temperature control group of male rats (MR, 22), normal temperature control group of mother rats (FR, 15), cold stress group of male rats (MC, 15), and cold stress group of female rats (FC, 15) .In the fourth generation of the offspring, the open field experiment and the elevated cross maze test were carried out.@*RESULTS@#In the open field experiment, there was no significant difference in spontaneous activity and exploration behavior between the normal temperature control group and the cold stress group (P＞0.05). In the elevated plus maze experiment, the retention time of the open arms, the number of open arms and the distance of the male and female rats in the cold stress group were significantly higher than those in the normal temperature control group (P＜0.05).@*CONCLUSION@#Prenatal maternal cold stress has no significant effect on spontaneous activity, exploration behavior and activity level of offspring, but the offspring have obvious abnormal behaviors with reduced anxiety behavior.

We explore the association of the mycoplasma infection with genital system tumor.Some index word including prostate cancer,cervical cancer,ovarian cancer and mycoplasma were used in some electronic databases (including PubMed,Web of Science,Chinese biomedical database,wanfang database,CNKI) to search literatures.The R software was used for the meta-analysis.The Newcastle-Ottawa Scale (NOS) was used to evaluate the quality of the literature.Publication bias was evaluated by funnel figure,and the fail-safe number (Nfs) was calculated to estimate the reliability of the meta-analysis.Result showed that 20 articles were included,the numbers of cases and controls were 2 345 and 2 728 respectively.The pooled OR of Ureaplasma urealyticum(Uu),Mycoplasma hominis(Mh),other mycoplasma,mixture of mycoplasma and the whole mycoplasma was 2.19(95％CI:1.27-3.79),1.74(95％CI:1.28-2.35),1.97(95％CI:1.03-3.77),3.54 (95％CI:1.33-9.41),1.29(95％CI:1.53-2.60),respectively.The fail-safe number of Uu,Mh,other mycoplasma and mixture of mycoplasma was 254,42,31,157 respectively.There are some possibility about the association between the mycoplasma infection and the genital system cancer;maybe the infection would increase the tumorigenesis risk.It is necessary to research further about these associations in different mycoplasmas respectively.
RESUMO
The study was aimed to observe mir-210 expression in liver tissue of acute cold stress rat and predict the function of mir-210 in cold stress. Thirty SPF Wistar male rats which were 12-week-old and weighed (340 ± 20) g were used. The rats were pre-fed in normal room temperature for one week, and then were randomly divided into acute cold stress group at (4 ± 0.1) °C and normal control group at (24 ± 0.1) °C. After the rats were treated with cold stress for 12 h, the liver tissue was extracted and the gene expression of mir-210 was assayed using qRT-PCR. The results demonstrated that the gene expression of mir-210 was significantly enhanced in acute cold stress group compared with that in normal control group (n = 3, P < 0.01). The bioinformatics analysis showed that mir-210 has over hundreds of target genes and four kinds of target genes such as E2F3, RAD52, ISCU and Ephrin-A3 are more relative with liver cold stress. ISCU regulates the cell respiratory metabolism and Ephrin-A3 is related with cell proliferation and apoptosis. On the other hand, up-regulated mir-210 affects the DNA repairing mechanism which usually leads to genetic instabilities. Our results suggest that cold stress-induced up-regulation of mir-210 in liver harmfully influences cell growth, energy metabolism and hereditary.
