Aim Of The Study: To analyze the progress in Mongolian medicine and medicinal materials and to highlight its development process, emerging trends, and hotspots.
Materials And Methods: Papers on Mongolian medicine and medicinal materials from January 2000 to May 2022 were retrieved from the China National Knowledge Infrastructure (CNKI) database. Using the collaboration network analysis of CiteSpace V and VOSviewer software, the cooperation among individuals and institutions in the field of scientific research was analyzed.

This paper aims to explore the inhibitory effect of Yueju Pills on breast cancer and decipher the underlying mechanism. A total of 92 SPF-grade SD female rats were involved in this study, and 14 of them were randomly selected into control group. The remaining 78 rats were administrated with 7,12-dimethylbenzanthracene(DMBA) by gavage to establish the breast cancer model.

Waste sludge is an important reservoir and discharge source for antibiotic resistance genes (ARGs). In this study, the quantities of seven tetracycline resistance genes (TC-ARGs), including , and , as well as those of class 1 integron () genes, during anaerobic sludge digestion process were comprehensively quantified by quantitative PCR (qPCR).

The spatial distribution and sources of the detected heavy metals were studied by enrichment factor and multivariate statistical and spatial interpolation analyses. In addition, their potential ecological risk was assessed.

Also, the concentrations of volatile fatty acids (VFAs) were determined. The correlations between the abundances of TC-ARGs and gene and the concentrations of VFAs were discussed.

Quantitative PCR (qPCR) was used to determine the abundance variance of four ciprofloxacin resistance genes (CIP-ARGs) during nitrification in biofilms. The correlations between the abundances of CIP-ARGs and nitrifying microorganisms were also discussed.

Effects of adsorption time, initial concentration, solution pH and temperature on the adsorption process were studied. The results showed that the adsorption process of these PPCPs onto sediments was a two-step process: a rapid adsorption followed by a slow balance.

Quantitative PCR (qPCR) was used to determine the distribution and removal of seven erythromycin resistance genes (ERY-ARGs). The results showed that five PPCPs including sulfamethoxazole, erythromycin, tetracycline, carbamazepine and triclosan were detected in the collected wastewater samples with concentrations in the ranges of 24.

However, the resistance to antimicrobials varies greatly among the P. aeruginosa isolates, which raises a question on whether some sub-lineages of P.

Aim: To investigate the characters and changes of peripheral lymphocyte subsets and cytokines in liver transplant receptors with HBV infection in short phases after liver transplantation, and to provide evidences for monitoring post-transplant immune condition of liver transplant receptors.
Methods: Peripheral lymphocyte subsets and cytokine levels in pre- and post- transplant 12 h, 3 d, 10 d, 30 d, 60 d of 20 cases of patients with HBV-associated severe hepatic diseases were investigated and analyzed, and were compared respectively with those of 22 cases of healthy adults as control (HC) with flow cytometry (FCM) and ELISA.
Results: The patients' accounts of peripheral lymphocyte subsets before liver transplantation were lower than those of HC significantly, but the accounts decreased significantly after transplantation 12 h.
Effects of different pretreatment protocols in (NH(4))(2)HPO(4) activation of rice straw on porous activated carbon evolution were evaluated. The pore structure, morphology and surface chemistry of obtained activated carbons were investigated by nitrogen adsorption, scanning electron microscopy and Fourier transform infrared spectroscopy. It was found that pretreatment combining impregnation with (NH(4))(2)HPO(4) and preoxidation could significantly affect the physicochemical properties of prepared activated carbons.

As mutation and recombination do occur in bacteria, it is of interest to understand how genetic novelty may be achieved in the presence of MMR. Previously, we observed associations of a defective MMR genotype, 6bpΔmutL, with greatly elevated bacterial mutability in Salmonella typhimurium.
