ABSTRACT
Apoptosis is particularly important for the body to inhibit or eliminate Mycobacterium tuberculosis ( Mtb) infection. A series of mechanisms to regulate macrophage apoptosis are triggered after macrophages are infected by Mtb. In Mtb-infected macrophages, there are differentially expressed microRNAs (miRNAs), which can directly bind to the binding sites in the 3′-untranslated region (3′ UTR) of apoptotic genes to regulate the expression of apoptotic genes and the apoptosis of macrophages through the mitochondrial or death receptor pathway. This paper reviewed the miRNAs associated with the apoptosis of Mtb-infected macrophages and the major mechanisms.

ABSTRACT
Interaction in classroom teaching is a bilateral activity that is difficult to control. Teachers and students are the two main aspects to realize the synchronization of teachers and students' thinking. For teachers, teachers should first make full use of multimedia resources, bring a colorful courseware into class-room teaching; secondly, teachers should stimulate students' interest in a reasonable way, so as to inject vitality into the classroom teaching; finally, teachers should mobilize the students' thinking and carefully regulate the changes in thinking between teachers and students through a proper teaching methods. In terms of students, students should not only give full play to their initiative, but also actively cooperate with teachers in order to realize the thought synchronization between teachers and students in classroom teaching and learning interaction and ultimately achieve the desired results.

ABSTRACT
Objective To reduce the screening positive rate (SPR) and improve clinical efficiency of maternal serum screening for Down's syndrome.Methods Nine thousand and thirty-three cases of second trimester maternal serum screening for Down's syndrome were included from Apr.2013 to Apr.2014 in the present study.The screening results,all basic data and equation curves were analyzed retrospectively.Based on the data from the authors' laboratory,the important adjustment parameters were simulated.Combined with postnatal follow-up results,the quality and clinical performance of second trimester serum screening for Down's syndrome were evaluated.Results The SPR of second trimester serum screening for Down's syndrome was 6.69％(604/9033),the detection rate (DR) was 75％(3/4),and FPR was 6.65％(601/9033).The median multiple of median (MOM) of alpha-fetoprotein (AFP) was low and SPR was high,and MOM of free human chorionic gonadotropin β subunit (free hCGβ) were high and SPR was high,while MOM of unconjugated estriol (uE3) were a little bit low,and SPR was slightly high.Considering these three factors,it is believed that the screening positive rate is high.By the simulation adjustments of MOM value equations (AFP and free hCGβ) and weight correction equation,the SPR reduced to 4.11％(371/9033) after recalculating the risk,FPR declined to 4.07％(368/9033),and no more Down's syndrome fetus were missed compared with postnatal follow-up results.Conclusion Based on a localized setting depending on the local laboratory data,we suggest that the MOM value distributions(AFP,free hCGβ and uE3) and maternal weight should be regularly adjusted since it is a useful way to reduce the false-positive rate and improve clinical efficiency of maternal serum screening for Down's syndrome.
