This study was aimed to clone the full-length cDNA sequence of actin gene of Eleutherococcus sentico-sus. And bioinformatics analysis was used. The total RNA was isolated from leaves of E. senticosus , and cDNA was synthesized by reverse transcription of total RNA. Primers were designed according to the conserved se-quence that had been cloned of Actin of E. senticosus . Then, the 3'and 5' cDNA fragments were cloned by nested PCR . The full-length gene was obtained by gene splicing method . Sequencing results were compared and treated with similarity analysis by blast analysis in the GenBank. Protein secondary structure and tertiary struc-ture of Actin of E. senticosus was predicted by online software. The results showed that the full-length cDNA of Actin of E. senticosus is 1507 bp, which named EsActin1, GenBank accession No. KC469585. The conserved sequence, which contained a 1134 bp open reading frame that encoding a 377 amino acid residues, a 5'-UTR of 140 bp and a 3'-UTR of 233 bp. Homologous alignment showed that it shared over 75% nucleotide se-quence similarity and over 94% amino acid sequences similarity with Actins in other plants. It was concluded that this study first isolated and reported the full-length cDNA sequence of actin gene of E. senticosus , and laid a foundation for the molecular biology research of E. senticosus .

OBJECTIVETo investigate the effect of the escharectomy during burn shock stage on expression of glucose translator-4 (GLUT4) mRNA in skeletal muscle and adipose tissue.

METHODS30% TBSA scalded rats were employed. Escharectomy were conducted at 8 h, 24 h, 168 h after burns respectively. Insulin, glucagon, cortisol and glucose levels in serum were analyzed. RT-PCR were employed to analyze GLUT4 mRNA expression in skeletal muscle and adipose tissue.

RESULTSGlucagon, cortisol and glucose levels in serum were declined in groups which escharectomy were conducted during burn shock stage. GLUT4 mRNA expression in both skeletal muscle and adipose tissue were downregulated after burns and escharectomy conducted during burn shock stage made it restored to near normal.

CONCLUSIONGLUT4 mRNA expression will declined after major burns in skeletal muscle and adipose tissue. Escharectomy during shock stage could make it upregulated, which will be helpful to improve glucose metabolism and hypermetabolism after major burns.

Accurate and rapid diagnosis of infectious diseases can effectively prevent their spread and promptly curb the epidemic hazards. Multiplexed point-of-care testing (x-POCT) technology can effectively avoid misdiagnosis caused by the detection of one single target and achieve rapid screening and timely control of multiple infectious diseases. Research progress and the latest applications of x-POCT including x-POCT assay methods for different targets in the diagnosis of infectious diseases and their pathogens are summarized in this review. The paper-based, microfluidic chip-based, and microdroplet-based device platforms of x-POCT, and eventually the challenges and future perspectives of x-POCT, especially progress on the effective infectious disease surveillance network establishment under One Health concept are highlighted.
