Persistent effects of adverse childhood experiences on the course of pubertal development / 中国学校卫生

Objective@#To explore the influence of adverse childhood experiences (ACEs) on pubertal development of boys and girls and to provide a reference for the development of intervention measures.@*Methods@#A stratified cluster sampling method was used to select a total of 1 156 students in grades three and four in the boarding school system and public primary schools in Huangshan City and surrounding towns in September 2018, using the Childhood Trauma Questionnaire (CTQ) and the Pubertal Development Scale (PDS). For the baseline self-assessment survey, according to different dimensions, abuse children score no exposure groups. Children were divided into an exposure group and a high exposure level group, according to their childhood experiences. PDS self-report questionnaire was administered two years later, and an analysis of ACE type and severity of the continuous impact of youth development was conducted.@*Results@#In the baseline survey, there were 53 girls (11.32%) and 51 boys (7.41%) who developed earlier. The rate of early development in girls was higher than that of boys, and the difference was statistically significant(χ 2=5.21, P<0.05). Univariate analysis showed gender differences in the effects of type and severity of ACEs and abuse on adolescent development at both baseline and follow-up. There were gender differences in the rate of early development between boys and girls at baseline and at follow-up between the exposure groups. Regression analysis showed that the higher the degree of emotional abuse, emotional neglect, and sexual abuse in girls, the higher the PDS score(B=0.22, 0.15, 0.08, P<0.05). In boys, the more severe the emotional abuse experienced, the higher the PDS score, and the more severe the physical abuse experienced, the lower the PDS score(B=0.20, 0.04, P<0.05).@*Conclusion@#Attention should be paid to the influence of ACEs and gender differences during youth development among male and female students, and more longterm studies should also be carried out.

Study on the level of D-lactic acid and the intestinal barrier function of children with hand, foot and mouth disease of different intestinal virus infection / 中国医师进修杂志

Objective To explore the variation of serum D-lactic acid levels and the correlation between different intestinal viral and intestinal barrier function in children with hand, foot and mouth disease (HFMD). Methods The stools of 129 children with HFMD were collected and were detected by reverse transcription polymerase chain reaction. The children were divided into four groups according the fecal pathogens detection:enterovirus 71 (EV71) positive group, Coxsackie virus A16 (CoxA16) positive group, other intestinal virus positive group (EA positive group), and no intestinal virus group (EA negative group). Two ml venous blood and separation serum was collected in each group of children, and the level of serum D-lactic acid was detected further. Results There were 20 cases of other Coxsackie virus, and they were not grouped. Fifty-seven patients were in EV71 positive group, 26 patients were in CoxA16 positive group, 10 patients were in EA positive group, and 16 patients were in EA negative group. The level of D- lactic acid in four groups was 26.28 (17.02- 58.01), 14.43 (8.93- 20.66), 10.66 (6.64- 18.51) and 14.07 (11.83- 27.46) mg/L. The results of rank test showed the level of D-lactic in EV71 positive group was significantly higher than that in EA positive group (Z=-2.432, P=0.015) and EA negative group (Z=-3.092, P=0.002). Conclusions D-lactic acid level increases significantly in EV71 infection children and suggests that the illness is more serious and the intestinal barrier is damaged. Doctors should pay more attention to monitor and protect gastrointestinal function of children with HFMD.

Objective To explore the relationship between G-protein β3 subunit (GNB3) gene C825T polymorphism and antipsychotic agent-induced obesity.Methods 126 schizophrenic inpatients with long-term antipsychotics treatment were collected.According to body mass index ( BMI),patients were divided into obesity group ( n =62) and non-obesity group ( n =64).The GNB3 gene C825T polymorphism was detected by polymerase chain reaction and DNA sequencing technique.Levels of fasting blood glucose,2-hour postprandial blood glucose,blood lipids and blood uric acid of all patients were routinely measured.Results (1)The GNB3 gene C825T polymorphism were found in obesity group and non-obesity group respectively,and the distribution of genotypes in two groups were both consistent with Hardy-Weinberg equilibrium.(2)There was no significant difference in genotype frequencies between obesity group ( CC 17.75％,CT 58.06％,TT 24.19％ ) and non-obesity group( CC 18.75％,CT 62.50％,T T 18.75％ )( x2 =0.59,P ＞ 0.05 ).There was also no significant difference in allele frequencies between obesity group ( C 46.77％,T 53.23 ％ ) and non-obesity group ( C 50％,T 50％ ) ( x2 =0.26,P ＞ 0.05 ).(3)No significant differences were observed in BMI,fasting blood glucose,2-hour postprandial blood glucose,blood lipids and blood uric acid among different genotype groups (all P ＞ 0.05 ).Also no significant differences were observed in BMI,fasting blood glucose,2-hour postprandial blood glucose,blood lipids and blood uric acid between Tallele carrier (TT and CT genotypes) and T-allele non-carrier( CC genotype) ( all P ＞ 0.05 ).Conclusion The GNB3 gene C825T polymorphism may not be a genetic risk factor for antipsychotic agent-induced obesity.

Effect of VEGF-C Gene Transfection on the Expression of VEGF-C in Human Cervical Carcinoma HeLa Cells and the Molecular Meehnisms of Its Anti-apoptosis Effect / 中国肿瘤临床

Objective: TO explore the effect of VEGF-C gene transfection on the expression of VEGF-C in human cervical carcinoma HeLa cells and the mechanisms of its anti-apoptosis effect. Methods: The con-structed pcDNA3.1(+)NEGF-C vector was transformed into human cervical cancer HeLa cells and was select-ed by G418. The changes in the expression level of VEGF-C mRNA and protein were determined by semi-quantitive RT-PCR and ELISA. HeLa cells with overexpression of VEGF-C were named as HeLa/S1. The expression level of NF-KB and bcl-2 mRNA was determined by RT-PCR in transfected cells. Results: After transfection by liposome, the VEGF-C mRNA level and the expression of VEGF-C protein in transfected cells were higher than those in the control groups. HeLa/S1 cell line was successfully established. In HeLa/S1 cells, the expression of NF-κB (2.06±0.09 vs 1.35±0.02 vs 1.38±0.02 P<0.05) and bcl-2 gene mRNA (2.02± 0.67 vs 0.41±0.06 vs 0.37±0.06, P<0.05) level were higher than those in the control groups. Conclusion: VEGF-C gene transfection by liposome can increase the expression of VEGF-C in human cervical cancer HeLa cells. NF-κB is stimulated and induces the overexpression of bcl-2 gene in HeLa/S1 cells.
