OBJECTIVETo study the correlation of G870A CCND1 gene polymorphism and digestive system tumors.

METHODSFrom August 2010 to August 2014, 164 digestive system cancer patients (including 82 patients with gastric cancer and 82 with colorectal cancer) and 82 healthy subjects (control group) were examined with PCR-restriction fragment length polymorphism (PCR-RFLP). The distribution of CCND1 gene G870A frequency in the 3 groups and its association with tumor staging and grading were analyzed.

RESULTSThe frequencies of the GG, GA and AA genotypes in G870A CCND1 gene loci in patients with gastric cancer and colorectal cancer differed significantly from those in the control group (P<0.05). G870A CCND1 gene polymorphism was closely associated with an increased risk of digestive system tumors (P<0.05). The GA and AA genotypes were associated with a significantly higher risk of digestive system cancer risk than the GG genotype (P<0.05), and their frequencies were significantly higher in patients with tumors of higher pathological grade and in those in advanced tumor stages (P<0.05).

CONCLUSIONG870A CCND1 gene polymorphism is associated with the risk of digestive system tumors. The allele A is associated with an increased risk of digestive system tumors and correlated with the tumor differentiation and staging of the tumor.

Objective To explore the personality characteristics of abused children in order to reduce the incidence of child abuse.Methods Two hundred and ninty five middle school students were investigated with general questionnaire and Eysenck Personality Questionnaire of children. Eighty six students experiencing child abuse (CA) last year as study group and one hundred and ninety six non-abuse children as controls (NCA) were analyzed by means of Eysenck Personality Questionnaire of children.Results The score of neuroticism in CA group was significantly higher than that in the control group (55.62±10.60/52.65±10.98,t=-2.114 P=0.035). The score of lie in CA group was significantly lower than that in control group (42.21±9.87/46.04±9.20,t=3.184 P=0.002). On the impact of different sex, the psychoticism score of male was significantly higher than that in the control group(52.37±11.49/48.04±9.97,t=-2.227 P=0.028), and the lie score was significantly lower than that in control group(41.03±9.18/46.18±8.79,t=3.125 P=0.002).The scores of those in the female were not significant.Conclusions There is a close association between the unstable emotion and child abuse in children, so training emotional self-control and emotional expression of children might be a intervention strategy in the future. In addition, the frequency of lie in children is probably one of factors that determine whether children are abused or not.

Objective To explore the relationship between childhood abuse experience,parent and peer attachment and depression in adolescents.Methods A total of 736 junior students from the 7th,8th and 9th grades of 2 public schools in Xinxiang City and Jiyuan City Henan province completed the questionnaires.Childhood Trauma Questionnaire(CTQ),Inventory of Parent and Peer Attachment(IPPA) and Depression Self-Rating Scale for Children(DSRSC) were employed the childhood abuse experience,parent attachment quality and depressive mood in adolescents,respectively.The hierarchical regression analysis was used to examine the relationship between parent and peer attachment,child abused experience and depression.Results Male participants reported high score of childhood abused than female participants(33.29±7.89 and 31.05±6.01,t=4.343,P=0.000).There were no significantly gender difference in mother attachment(male:59.89±15.86,female:61.45±16.48,t=-1.303,P=0.193),father attachment(male:59.32±17.17,female:60.28±16.95,t=-0.764,P=0.445) and depression(male:7.68±5.27,female:7.31±4.21,t=1.057,P=0.291).Childhood abuse had a positive correlation with adolescent depression(r=0.408,P=0.000),which negatively correlated with mother and father attachment(r=-0.544,-0.417,respectively,Pa=0.000).There was a positive correlation between mother attachment and father attachment(r=0.604,P=0.000),and both of them had negative correlation with depressive disorder(both r=-0.426,Pa=0.000).Mother and father attachment were the partial mediation of the relationship between childhood abuse and adolescent depression.Conclusions Male adolescents suffered more maltreatment than female adolescents.There are no gender difference in parent attachment and depression.Parent attachment plays the partial mediator role in childhood abuse and adolescent depression.Results reveal the importance of assessment and consideration of parent attachment in the intervention of depression in abused adolescents.

Objective To analyze the status of mycoplasma infection and drug resistance in the local area,and provide the ba-sis for clinical rational drug use.Methods The specimens obtained from 1 9 530 patients with urogenital tract infection were detec-ted by adopting mycoplasma culture,identification and drug sensitivity integration kit.Mycoplasma infection and drug susceptibility were analyzed.Results In the total of 1 9 530 suspected patients specimens,1 1 1 78 cases were positive with a positive rate 57.24%.The positive rate of ureaplasma urealyticum (Uu)and mycoplasma hominis (MH)was 44.63% and 0.44% respectively and the positive rate of Uu and Mh mixed infection was 12.1 7%.The positive rate of female was higher than that of male and the difference was statistically significant(P <0.05).The positive rate of mycoplasma in 2008-2014 was on the rise;The sensitive rate of mycoplasma to josamycin,doxycycline,minocycline element,clarithromycin was 88.57%,84.32%,76.09% and 71.53% respec-tively,mycoplasma was highly drug resistance to quinolone antibiotics;mixed infection resistance was higher than that of single in-fection;The number of drug resistance of Uu,MH and Uu+MH to 12 kinds of antibiotics increase.Conclusion Mycoplasma infec-tion in urogenital tract is mainly caused by Uu and Mh infection is in mixed infection way;josamycin,doxycycline is the first choice for treatment of mycoplasma in this region.Rational drug choise can be based on the drug susceptibility test.Multiple drug resist-ance of mycoplasma is serious and should be paid attention to.

Atractylodis Macrocephalae Rhizoma and Atractylodis Rhizoma were widely used in strengthening spleen under different disease conditions, and were easily and often misused each other. Therefore, DNA barcode was used to distinguish Atractylodis Macrocephalae Rhizoma and Atractylodis Rhizoma from their adulterants to ensure the safe use. The sequence lengths of ITS2 of Atractylodes macrocephala, Atractylodis Rhizoma (A. lancea, A. japonica and A. coreana) were both 229 bp. Among the ITS2 sequences of A. macrocephala, only one G/C transversion was detected at site 98, and the average GC content was 69.42%. No variable site was detected in the ITS2 sequences of A. lancea. The maximum K2P intraspecific genetic distances of both A. japonica and A. coreana were 0.013. The maximum K2P intraspecific genetic distances of A. macrocephala, A. lancea, A. japonica and A. coreana were less than the minimum interspecific genetic distance of adulterants. The ITS2 sequences in each of these polytypic species were separated into pairs of divergent clusters in the NJ tree. DNA barcoding could be used as a fast and accurate identification method to distinguish Atractylodis Macrocephalae Rhizoma, Atractylodis Rhizoma, from their adulterants to ensure its safe use.
