ObjectiveTo explore the intervention effect of Erxian decoction on intestinal microflora after ovariectomy in rats by 16S rRNA gene sequencing. MethodThirty-two female healthy SD rats were randomly divided into a Sham operation （Sham） group， a model （OVX） group， an estrogen （E） group， and an Erxian decoction （EXD） group， with 8 rats in each group. The rats in the E group and the EXD group received 1.8×10-4 g·kg-1 estradiol valerate solution and 9 g·kg-1 Erxian decoction， respectively， and those in the Sham group and the OVX group received an equal volume of distilled water once a day for 16 weeks. After 16 weeks， the levels of serum estrogen and blood lipid were detected. The fecal DNA was extracted， followed by 16S rRNA gene sequencing and analysis. ResultCompared with the Sham group， the OVX group showed reduced serum estrogen level （P<0.01） and increased serum levels of total cholesterol （TC） and low-density lipoprotein cholesterol （LDL-C） （P<0.05）. Compared with the OVX group， the E group and the EXD group showed increased serum estrogen level （P<0.01） and reduced TC and LDL-C （P<0.05）. Alpha diversity showed that there was no significant change in intestinal microflora diversity after ovariectomy. Beta diversity showed that there were significant differences in the structure of intestinal microflora in the four groups. The intervention of Erxian decoction could improve the changes in intestinal microflora after ovariectomy. LEfSe was used to analyze the differential flora in the four groups. The results showed that the Sham group and the OVX group had 3 differential bacterial phyla and 18 differential bacterial genera， the OVX group and the E group had 1 differential bacterial phylum and 12 differential bacterial genera， and the OVX group and the EXD group had 3 differential bacterial phyla and 5 differential bacterial genera. Estrogen intervention could reverse the change trend of Ruminococcus 1， Anaerovibrio， and Turicibacter in the OVX group. Erxian decoction intervention could reverse the change trend of Bacteroidetes， Firmicutes， Prevotella 9， Ruminococcaceae UCG-014， Ruminococcus 1， and Fusicatenibacter in the OVX group. ConclusionThe structure and function of intestinal microflora in ovariectomized rats changed obviously， and Erxian decoction could ameliorate the change.

Changes in Ileal Flora Induced by Qishengwan in Treatment of Alzheimer's Disease： An Exploration Based on "Interior-Exterior Relationship Between Heart and Small Intestine" / 中国实验方剂学杂志

ObjectiveTo explore the effect of Qishengwan on ileal flora during its treatment of Alzheimer's disease （AD） under the guidance of the theory of "interior-exterior relationship between heart and small intestine". MethodThe AD model was established by bilateral intraventricular injection of β-amyloid 1-42 （Aβ1-42）. The rats were then randomly divided into the blank group， sham-operated group， model group， low-， medium-， and high-dose （5.6， 11.2，22.4 g·kg-1·d-1） Qishengwan groups， and donepezil （0.46 mg·kg-1·d-1） group. After medication for 28 successive days， the spatial memory ability of rats was observed in water maze test， and the levels of Aβ1-42， nuclear transcription factor-κB （NF-κB）， tumor necrosis factor-α （TNF-α）， and interleukin-6 （IL-6） in the hippocampus were analyzed by enzyme-linked immunosorbent assay （ELISA）. Additionally， the contents of the ileum were collected and subjected to 16SrRNA-sequencing analysis for figuring out the changes in ileal flora. ResultCompared with the blank group and sham-operated group， the model group exhibited significantly reduced stay time in the target quadrant and number of target quadrant and platform crossings （P<0.05， P<0.01） and elevated Aβ1-42 content in the hippocampus （P<0.01） and central inflammatory factors NF-κB， TNF-α， and IL-6 （P<0.05， P<0.01）. Compared with the model group， Qishengwan at each dose significantly alleviated the impaired spatial memory function （P<0.05， P<0.01）， improved the deposition of Aβ1-42 in the hippocampus of rats （P<0.05， P<0.01）， and reduced the expression of central nervous system inflammatory factors （P<0.05， P<0.01）， thus exerting a good therapeutic effect on AD rats. The 16SrRNA-sequencing analysis results showed that the structure of the ileal flora in the model group was significantly separated from those in the blank group and sham-operated group. The abundance of Lachnospiraceae NK4A136 group was significantly increased （P<0.01）， while that of Escherichia-Shigella was reduced （P<0.05， P<0.01）. Qishengwan at each dose significantly changed the ileal flora structure and regulated the relative abundance of Lachnospiraceae NK4A136 group， Escherichia-Shigella， and Ruminococcaceae. ConclusionQishengwan has a positive therapeutic effect on AD. It can significantly enhance the memory and cognitive abilities in AD rats， which may be related to its regulation of the structure of rat ileal flora and the relative abundance of Lachnospiraceae NK4A136 group， Escherichia-Shigella， and Ruminococcaceae， the attenuation of the central neuroinflammatory response， and the reduction of central Aβ1-42 deposition.

Construction of combined site-directed random mutation libraries of recombinant human lymphotoxin / 生物工程学报

To construct the combined site-directed random mutation library of recombinant human Lymphotoxin (rhLT) for in vitro molecular evolution study, and to study the structure and function relationship. The random point mutations at the sites of 46,106 and 130 were individually generated by overlap PCR amplification with the random nucleotide primers. The three point mutations were combined and cloned into pMD-18T vector to construct the combined mutation library. DNA sequencing was used to evaluate the diversity and randomness of the mutation sites. The combined mutation library was re-engineered, inserted in prokaryotic expression vector pBV220, transformed and expressed in Escherichia coli strain DH5alpha. The biological activity of some of the mutants was tested in 1929 mouse fibroblast cells. As much as 1.5 x 10(5) clones were obtained, which represents 4.5 times of the complete mutation libraries at 99% confidence. Sequencing 50 clones revealed no obvious bias in the nucleotide and amino acid mutations at the sites. Among the 30 expressed samples underwent for the bioassay, 70% (21 samples) were inactive, 23.3% (7 samples) had lower activity than rhLT, the remaining 6.7% (2 samples) had higher activity than rhLT. The combined site-directed random mutation library of rhLT has been constructed successfully. In combination with phase display, the library is ready for in vitro molecular evolution study.
