Human-animal parasitic diseases caused by medical helminths are hazardous to human health. Genetic polymorphism studies on medical helminth populations can not only understand the biological characteristics and genetic structure of their populations, but also help reveal how they adapt to their parasitic environment, thus contributing to deepen our understanding of the epidemiological patterns of parasitic diseases and improve our understanding of accurate prevention and control of parasitic diseases. With the development of molecular biology, molecular markers such as DNA barcodes, simple sequence repeats, and single nucleotide polymorphism markers have been widely used to study the genetic relationships among parasite populations and individuals, and to reveal the genetic variation of parasite populations and the evolution of species origins. In this paper, we systematically review the application of three molecular markers commonly used in the study of genetic polymorphism in medical helminths, with a view to laying the foundation for related research.

OBJECTIVETo investigate the psychological well-being among adolescents of HIV-positive parents.
METHODSThis study was involving 298 adolescents from 10 to 18 years old, including 54 adolescents of both parents living with AIDS or HIV, 114 adolescents of one parent living with AIDS or HIV and another 130 adolescents from normal families. Only one adolescent was studied per family. All participants completed an anonymous questionnaire. Psychological health, satisfaction on life, self-esteem and coping style were evaluated by SCL-90, Multidimensional Students' Life Satisfaction Scale, Self-esteem Scale and Simplified Coping Style Questionnaire.
RESULTSThe total score and 10 factors of the SCL-90 in the adolescents of parents living with HIV or AIDS was higher than the adolescents from normal families and those scores in the adolescents of both parents living with HIV or AIDS were the highest. There were 27.8% of the adolescents with both HIV-positive parents were having the total score of SCL-90 more than 160 or at lest one of the 10 factors' score more than 3. The detected rate of adolescents with one HIV-positive parent was 16.7%, higher than those adolescents from normal families (8.5%) and with significant difference (chi2 = 11.457, P = 0.003). 50.0% of the adolescents with both HIV-positive parents, were having one or more factor' score between 2.0 and 3.0, compared to the rate (37.0%) of adolescents with one HIV-positive parent. The rate was higher than the adolescents from normal families (29.8%) and with significant difference (chi2 = 7.250, P = 0.027). Among the students from normal families, the total score and the 5 dimensionalities' score of the MSLSS were lower than those adolescents of parents living with AIDS or HIV. In the friend dimensionality, the score of the adolescents from normal families was significantly higher than the adolescents of parents living with AIDS or HIV. The scores of self-esteem, positive coping style and negative coping style were not significantly different in three different subjects.
CONCLUSIONThe psychological status of the adolescents of parents living with AIDS or HIV indicated unoptimistic situation.

Objective To observe the effects of Yiqi Jiedu prescription drug serum on the apoptosis of human renal cell carcinoma ACHN cells and Notch1 gene in Notch signal pathway. Methods The healthy SD female rats were selected, which were divided into 4 groups, 8 rats in each group: the rats were fed with the normal saline 10 ml·kg-1·d-1 (the blank serum group); the rats were fed with the Yiqi Jiedu prescription decoctum of 50 g·kg-1·d-1 (the high-concentration of Yiqi Jiedu prescription serum group); the rats were fed with the Yiqi Jiedu prescription decoctum of 25 g·kg -1·d -1 (the medium-concentration of Yiqi Jiedu prescription serum group); the rats were fed with the Yiqi Jiedu prescription decoctum of 12.5 g·kg-1·d-1 (the low-concentration medicated of Yiqi Jiedu prescription serum group); then the serum would be extracted 10 days later in each group. ACHN cells at exponential phase were cultured in the above 4 groups. Theproliferation of ACHN cells in each group was observed by using CCK-8 method. The apoptosis of ACHN cells was detected by using flow cytometry (FCM). The expression levels of Notch1 mRNA of ACHN cells in each groups were detected by using real time fluorescence quantitative polymerase chain reaction (RT-PCR). Results The inhibition rates of ACHN cells in the high-concentration group, the medium-concentration group, the low-concentration group of Yiqi Jiedu prescription and the blank serum group 24 h later were (12.34±4.25)%, (7.47±1.40)%, (2.52±0.62)%, (1.05±0.31)%, respectively (F= 15.04, P< 0.01); after 48 h, the inhibition rates were (24.20 ±2.41)%, (14.23 ±1.56)%, (5.08 ±1.34)%, (1.16 ±0.14)%, respectively (F=227.36, P<0.01);after 72 h, the inhibition rates were (32.16±2.45)%, (25.05±3.69)%, (10.29±2.76)%, (1.07± 0.71)%, respectively (F=110.51, P<0.01). The results showed that Yiqi Jiedu prescription drug serum could significantly inhibit the proliferation of ACHN cells in a dose-dependent manner. Besides, the inhibition rate differences at all time points of the high-concentration serum group (F= 31.44, P< 0.01), the medium-concentration serum group (F= 49.61, P< 0.01) and the low-concentration serum group (F= 68.78, P<0.01) were all statistically significant, and they were in a time-dependent manner. The apoptosis rate of cells in the high-concentration group, the medium-concentration group, the low-concentration group of Yiqi Jiedu prescription and the control serum group was (34.5±1.5)%, (24.4±1.5)%and (13.1±0.5)%, (5.2±0.3)%, respectively, and the differences were statistically significant (F = 1153.36, P < 0.01). The relative expression level of Notch1 mRNA of cells in the high-concentration group, the medium-concentration group, the low-concentration serum group of Yiqi Jiedu prescription and the control serum group was 0.213 ±0.032, 0.432 ±0.049, 0.781 ±0.018, 1.013 ±0.047, respectively, and the differences were statistically significant (F=270.60, P<0.01). Conclusion Yiqi Jiedu prescription drug serum can induce apoptosis of ACHN cells, and its mechanism may be related to the down-regulation of the expression level of Notch1 receptors.
