Article Abstract
Rapid allele-specific PCR primer was designed base on Cytb 155 A/T single nucleotide polymorphism, DNA was extracted by alkaline lysis and the PCR reaction systems including denatured and annealing temperature and cycle numbers were optimized. The results were performed to authenticate Ranae Oviductus and its 4 adulterants. When 100×SYBR Green I was added in the PCR product at 90 ℃ denatured 3 s, 62 ℃ annealing 20 s and 32 cycle. Ranae Oviductus visualized strong green fluorescence under 365 nm UV lamp whereas adulterants appeared negative. The whole process can be completed in 40 minutes．The established method provides the technical support for authentication of the Ranae Oviductus.

Article Synopsis
- - The study focuses on the genome analysis of a significant aquaculture species in Northeast China, which highlights the economic value of female individuals due to their use in traditional medicine.
- - Using next-generation sequencing, researchers obtained extensive genomic data, characterizing the genome's size, heterozygosity, and gene content, while generating 270,785 contigs and 498 scaffolds.
- - The research identifies homologies with male-specific DNA markers and suggests that there may be additional genes influencing the sex determination mechanism in this species, indicating complexity beyond previously recognized factors.

Oviductus Ranae is the dried oviduct from Rana dybowskii, a forest frog species with medicinal, tonic, and cosmetic properties. Due to the high price and resource shortage, counterfeit varieties of Oviductus Ranae often appear in the market. However, traditional identification methods cannot accurately differentiate between Oviductus Ranae and its adulterants.

The oviduct of female Rana dybowskii is a functional food and can be used as a component of Traditional Chinese medicine. The differentially expressed genes enriched was screened in cell growth of three Rana species. We quantitatively analyzed 4549 proteins using proteomic techniques, enriching the differentially expressed proteins of Rana for growth and signal transduction.

In this study, 1-methylhydantoin cinnamic imides were synthesized from 1-methylhydantoin and -cinnamic acid, and their anti-inflammatory activity was investigated. The anti-inflammatory activity in vitro was evaluated by measuring the contents of NO, TNF-α and IL-1β in the supernatant of RAW264.7 cells stimulated by LPS.
