Objective: To investigate the nephroprotective potential of orally administered bracken extract against renal damage in quails, induced by a high-purine diet, to form a foundation for subsequent clinical studies and applications.
Materials And Methods: A mass spectrometry analysis was conducted on the pteridophyte subjected to steam explosion. Network pharmacological methods were then utilized to pinpoint shared targets and pathways, which suggested that has a capability to counteract renal injury.
The differences of transitional components and metabolic processes of Huatan Jiangqi Capsules(HTJQ) in rats under normal physiological and pathological conditions of COPD were analyzed by UPLC-Q-TOF-MS. The rat COPD model was established by passive smoking and intratracheal instillation of lipopolysaccharide. After the normal and COPD model rats were douched with HTJQ, the blood was collected from hepatic portal vein and the drug-containing serum samples were prepared by methanol precipitation of protein.

The FA-GNA-MNPs have been prepared by a facile method, which have been further characterized by SEM, TEM, IR and UV-vis spectra. And the cytotoxicity of FA-GNA-MNPs to HeLa and A549 cells was assessed using the MTT assay.

Methods: By taking embryogenic calluses of tetraploid of Dioscorea zingiberensis as propagation materials, the influential factors such as components of artificial endosperm, seed coats,storage conditions and germination materials on germination and seedling of the synthetic seeds were evaluated.
Results: When 4% alginate +2% CaCl2 + 2% chitosan was served as seed coat materials, and 1/2 MS +0.
Breeding is not only an important area of medicinal plants research but also the foundation for the superior varieties acquirement of medicinal plants. The rise of modern biotechnology provides good opportunities and new means for medicinal plants breeding research in China. Biotechnology shows its technical advantages and new development prospects in breeding of new medicinal plants varieties with high and stable yield, good quality, as well as stress-resistance.

To achieve sustainable resources use of Polygonum multiflorum, adventitious roots were efficiently induced and cultured by suspension culture. In order to obtain optimal medium for induction adventitious roots from the young stems of P. multiflorum, MS medium was optimized by supplementing with different concentrations of sucrose and plant growth substances.

Methods: Plantlet of Dioscorea zingiberesis in vitro was obtained by using apical meristem as explant. The different parts of the plantlets were cultured to select the best explant used for inducing callus and embryoids.
Objective: To establish and optimize the rapid propagation system of Polygonum multiflorum, as well as explore method for induction and identification of autotetraploid.
Method: Propagation medium was optimized by orthogonal test. The buds were immersed in colchicine solution with different concentrations for different time to select induction conditions for autotetraploid of P.
The title polycyclic alkaloid, C22H26N2O3, an indole derivative obtained from Melodinus yunnanensis, comprises three chiral C atoms and crystallizes as a racemate. Its seven-membered heterocyclic ring has a twisted conformation, with the N atom within the plane of the indole moiety and with two adjacent C atoms deviating in opposite directions from its plane by 0.756 (3) (methyl-ene C) and -0.

Objective: To explore the clinical effect and appropriate power of high-intensity focused ultrasound (HIFU) in the treatment of infant hemangioma.
Methods: 80 infants with hemangioma were randomly divided into four groups, 20 cases in each group. All cases in group A, B and C were irradiated on the lesion surface with 3-5 mm/s speed for five continuous come-and-goes using HIFU, with frequency 9 MHz, impulse 1 000 Hz and 10% scanning overlap.
The exotic species Spartina anglica, introduced from Europe in 1963, has been experiencing a decline in the past decade in coastal China, but the reasons for the decline are still not clear. It is hypothesized that competition with the native species Scirpus triqueter may have played an important role in the decline due to niche overlap in the field. We measured biomass, leaf number and area, asexual reproduction and relative neighborhood effect (RNE) of the two species in both monoculture and mixture under three nitrogen levels (control, low and high).
