The intestinal flora is a micro-ecosystem that is closely linked to the overall health of the host. We examined the diversity and abundance of intestinal microorganisms in mice following the administration of andrographolide, a component of the Chinese medical herb Andrographis paniculata. Administration of andrographolide produces multiple beneficial effects including anti-inflammatory, antiviral and antibacterial effects but whether it directly influences the gut microbiota is not known. This study investigated whether the oral administration of andrographolide influences the intestinal microbiota and was compared with amoxicillin treatment as a positive control and water only as a negative control. We examined 21 cecal samples and conducted a high-throughput sequencing analysis based on V3-V4 variable region of the 16S rDNA genes. We found that the diversity and abundance of mouse gut microbiota decreased in direct proportion with the amoxicillin dose whereas andrographolide administration did not affect intestinal microbial community structure. The composition of intestinal microbes following andrographolide treatment was dominated by the Firmicutes while Bacteroidetes dominated the amoxicillin treatment group compared with the negative controls. Specifically, the f__Lachnospiraceae_ Unclassified, Lachnospiraceae_ NK4A136_group and Ruminococcaceae_ UCG-014 were enriched with andrographolide administration while Bacteroides, Klebsiella and Escherichia-Shigella significantly increased in the amoxicillin test groups. Amoxicillin administration altered the microbial community composition and structure by increasing the proportion of pathogenic to beneficial bacteria whereas andrographolide administration led to increases in the proportions and abundance of beneficial bacteria. This study provides a theoretical basis for finding alternatives to antibiotics to decrease bacterial resistance and restore intestinal floral imbalances.

The frequency of structural chromosomal transpositions can range from 1.8 to 8% among patients with reproductive disorders. There are several types of the rarest chromosomal abnormalities: insertion (insertion of a chromosomal region) and inversion (rotation of a chromosome region). This article describes a clinical case of the infertility treatment using assisted reproductive technologies in a woman with a rare chromosomal abnormality: simultaneous insertion and inversion of chromosomes 46, XX, ins (13;4)(q34;p14p15.3), inv(4)(p14q12). The structure and frequency of chromosomal aberrations were determined by high-throughput sequencing in preimplantation embryos. The result of the sequencing analysis showed that unbalanced variants for a known pathology were detected in 9 (56.3%) out of 16 observations, while in 6 (37%) only for a pathology known in the karyotype and in 3 (19%) they were presented simultaneously with the pathology of other chromosomes or with mosaicism. According to the results of the study, in preimplantation embryos, where one of the parents had chromosomal abnormalities, in addition to unbalanced variants, there is aneuploidy of other chromosomes not involved in the known pathology. They are described in 3 (21%) out of 14 observations of all identified pathology. In this regard, patients with aberrations in the karyotype are recommended, whenever possible, to carry out preimplantation genetic testing of structural rearrangements by methods allowed to analyze all chromosomes simultaneously. For example, high-throughput sequencing on the Illumina platform may become an alternative for prenatal diagnostics, which is performed in fertile couples with high risk of having a child with hereditary or congenital disorders. In the case of detection of chromosomal changes in the fetus, patients are faced with a number of ethical issues related to the necessity for medical abortion, which may contradict their religious and moral convictions.
