The role of methylation of placental glucocorticoid response gene in the association between pregnancy-related anxiety in the third trimester and birth outcomes / 中华预防医学杂志

Objective: To investigate the role of methylation of placental glucocorticoid response gene in the association between pregnancy-related anxiety in the third trimester and birth outcomes. Methods: Based on a prospective cohort study, singleton live births and their mothers from the Ma'anshan Birth Cohort Study (MABC) were included as participants in this study. The maternal pregnancy-related anxiety symptoms in the third trimester of pregnancy were evaluated by using the Pregnancy-related Anxiety Questionnaire. The neonatal birth outcomes were collected from medical records. The placental tissues from 300 pregnant women with pregnancy-related anxiety and 300 without pregnancy-related anxiety were collected to detect the methylation of FKBP5, NR3C1 and HSD11B2 genes using the Methyl Target approach. The methylation factors were extracted by exploratory factor analysis. Linear regression or logistic regression models were used to analyze the association between pregnancy-related anxiety in the third trimester, methylation factor scores, and birth outcomes. The mediating role of methylation factors in the association between pregnancy-related anxiety in the third trimester and birth outcomes was analyzed by using the Process procedure. Results: The mean age of 2 833 pregnant women was (26.60±3.60) years old. After adjusting for confounding factors, pregnancy-related anxiety in the third trimester increased the risk of small-for-gestational-age (OR=1.32, 95%CI:1.00-1.74). A total of 5 methylation factors were extracted, and the factor 5 was loaded with FKBP5 CpGs 18-21. Pregnancy-related anxiety in the third trimester was negatively correlated with the factor 5 (β=-0.24,95%CI:-0.44--0.05). The factor 5 was positively correlated with the gestational age (β=0.17, 95%CI:0.06-0.27). In addition, the factor 2 (β=0.02,95%CI:0.00-0.04) and factor 3 (β=0.03,95%CI:0.01-0.05) were positively correlated with 5-min Apgar score after delivery. However, this study did not found the mediating role of the scores of the factor characterized by FKBP5 in the relationship between pregnancy-related anxiety and birth outcomes. Conclusion: Pregnancy-related anxiety in the third trimester may reduce the methylation level of FKBP5 CpGs 18-21 in placental tissues and is associated with the risk of small-for-gestational-age.

Expression level and function of MEX3A in non-small cell lung cancer / 中国肿瘤临床

Objective: To investigate the expression of MEX3A in non-small cell lung cancer (NSCLC) cells and the effects of MEX3A knockout on cell cycle, proliferation, invasion, migration, and apoptosis. Methods: We screened out MEX3A, which was significantly highly expressed, by mRNA microarray and The Cancer Genome Atlas (TCGA) database information analysis. Quantitative real-time polymerase chain reaction (qRT-PCR) was used to detect the expression level of MEX3A in NSCLC cells. A549 and NCI-H292 cells showed high expression of MEX3A. RNA interference (RNAi) method was used to silence MEX3A in A549 and NCI-H292 cells. Cell counting kit-8 (CCK8) and Transwell assays were used to determine the effects of MEX3A knockout on proliferation, invasion, and migration in NSCLC cells. Flow cytometry was used to analyze the effects of MEX3A knockout on cell cycle and apoptosis. Results: A549 and NCI-H292 cells showed high expression of MEX3A. After silencing MEX3A, the proliferation, invasion, and migration of NSCLC cells were significantly decreased, while the cell cycle was blocked at G2/M phase and its apoptotic ability was weakened. Conclusions: MEX3A may play an important role as an oncogene in the growth and proliferation of NSCLC cells.

@# <b>Objective:</b>to observe the effect and mechanism of lumbricus peptides on early renal injury in spontaneous hypertensive rats (SHR) based on Toll-like receptors 4 (TLR4)/nuclear factor-<i>κ</i>B(NF-<i>κ</i>B) signaling pathway. <b>Method:</b>The 40 SHRs were randomly divided into model group (equal volume of distilled water by intragastric administration), lumbricus peptides low, middle and high dose groups (126, 252, 504 mg·kg^-1), and Benazepril group (0.9 mg·kg^-1), <i>n</i>=8 in each group. 8 male rats with normal blood pressure at the same age were set as the normal control group,with equal volume of distilled water. After treatment for 60 consecutive days, enzyme-linked immunosorbent assay (ELISA) was used to determine microalbumin (mAlb)and <i>N</i>-acetyl-<i>β</i>-<i>D</i>-glucosaminidase (NAG) content in 24 h urine as well as the level of serum angiotensinⅡ (AngⅡ). Ultrastructural changes of rat kidneys were observed by transmission electron microscope. Western blot was used to detect renal TLR4, NF-<i>κ</i>B p65 protein levels. Immunohistochemical method was used to detect renal tumor necrosis factor-<i>α</i> (TNF-<i>α</i>) and interleukin 10 (IL-10) expression. <b>Result:</b>As compared with the normal control group, the levels of urine mAlb, NAG and serum Ang Ⅱ were increased in the model group (<i>P</i><0.05); the expression of TLR4 and NF-<i>κ</i>B p65 protein was increased (<i>P</i><0.05); expression of TNF-<i>α</i> was increased (<i>P</i><0.05), while IL-10 expression was decreased (<i>P</i><0.05). Transmission electron microscopy of kidney tissues showed that most of the glomeruli of the model group had podocyte foot process fusion, mesangial cells and mesangial matrix hyperplasia. As compared with the model group, the levels of urine mAlb, NAG, and serum Ang Ⅱ were decreased in the rats in lumbricus peptides groups and benazepril group (<i>P</i><0.05); the expression of TLR4 and NF-<i>κ</i>B p65 protein was decreased (<i>P</i><0.05); the positive expression of TNF-<i>α</i> in kidney was decreased to different extent (<i>P</i><0.05), but the expression of IL-10 was increased (<i>P</i><0.05). Transmission electron microscopy of kidney tissues showed that the damage of kidneys in rats after administration of high-dose lumbricus peptides and benazepril was improved in varying degrees. <b>Conclusion:</b>lumbricus peptides can reduce early renal damage in SHRs, and its mechanism may be achieved by regulating the AngⅡ-TLR4/NF-<i>κ</i>B pathway.

Polymorphism of XRCC1 gene and its relation with genetic susceptibility of nasopharyngeal carcinoma in chinese living in jiangsu, zhejiang province and shanghai / 第二军医大学学报

Objective To study the polymorphism of XRCC1 gene and its relation with genetic susceptibility of the nasopharyngeal carcinoma (NPC) in Chinese living in Jiangsu, Zhejiang Province and Shanghai. Methods A case-control study was performed with 87 NPC patients and 94 healthy controls ofHan nationality in Chinese living in Jiangsu, Zhejiang Province and Shanghai. The two groups were matched by sex and age. PCR-RFLP technique was used to explore the relation of different XRCC1 polymorphismswith the susceptibility of NPC. Results The frequencies of the genotypes of XRCC1 Argl94Trp and Arg399Gln were similar between NPC andcontrol groups. The risk of NPC individuals with the Trp194Trp genotype was reduced compared with that in those with Argl94Arg genotype, but with no significant differences (0R = 0. 41, 95% CI:0. 081. 65, P = 0. 21). No association was observed between the genetic susceptibility ofNPC and other Argl94Trp variants or all Arg399Gln variants. Conclusion Our findings suggest that the polymorphism of XRCC1 has no association with the risk of nasopharyngeal carcinoma inChinese living in Jiangsu, Zhejiang Province and Shanghai, but the Trp194Trp variant genotype may be associated with a reduced risk of NPC.

Assessment of efifcacy of GnRH analogs by LHRH stimulation test in children with central precocious puberty / 临床儿科杂志

Objective To evaluate and monitor the efifcacy of GnRH analogs (GnRHa) therapy. Methods Thirty girls with central precocious puberty diagnosied by LHRH stimulation test were treated with GnRHa for 6-24 months. The LHRH stimula-tion test were performed again at 3 months after initiation of therapy and then every 6 months during treatment. The relationship of peark LH and clinical suppressing pubertal (including Turner stage, bone age, grwoth speed) were compared. The monitor effect of peak LH to efifcacy of GnRHa were eveluated. Results Ninety LHRH stimulation tests were performed, only 7 cases were found to have clinical pubertal development. After 6 months treatment, the base LH level of thirty girls (0.48±0.20) IU/L was signiifcantly lower than that before the treatment (0.75±0.35 IU/L) (P=0.000). The correlation coefifcient between base LH and peak LH was 0.62. The best correlation between clinical suppressing pubertal and LHRH stimulation test was achieved when peak LH was less than 2 IU/L (85.7%sensitivity, 100%speciifcity). Conclusions Base LH value can be used in preliminary as-sessment of the efifcacy of GnRHa therapy for girls with central precocious puberty. The peak LH less than 2 IU/L can be as the indicator of treatment efifcacy.
