Brown adipose tissue(BAT), a metabolically active organ, not only plays a pivotal role in thermogenesis, but also exerts endocrine effects that regulate both its own metabolic processes and the function of various other organ systems. These effects are primarily mediated by brown adipose tissue-derived factors, or batokines. Recent advances in the understanding of batokine types, target organs, and underlying mechanisms have highlighted their significant role in the crosstalk between BAT and other organs. This review focuses on the various batokines secreted by BAT and their involvement in regulating interactions with key target organs such as the liver, cardiovascular system, skeletal muscle, and nervous system. By examining the specific functions and molecular mechanisms of these factors, this review aims to offer novel insights and suggest potential research directions for the prevention and treatment of related metabolic diseases.

OBJECTIVE：To p rovide policy suggestions for the development and supervision of online drugstores in China. METHODS：By literature review ，the relevant literatures and policy documents about the development of online drugstores were searched，screened and sorted out to summarize the development process of China ’s internet drug trading mode and policy ，analyze the development status of China ’s online drugstores ；on the basis of the development experience of some developed countries ，the suggestions were put forward for China ’s relevant policies. RESULTS & CONCLUSIONS ：China’s medical e-commerce started relatively late ，and the policies related to online drug trading were basically released during last 20 years. The number of online drugstores showed a growing trend. The online drugstores were geographically allocated widely but unevenly. They sold many varieties，and policies on selling prescription medicines were gradually liberalized. These online drugstores provided diverse payment and delivery choices ，but their pharmaceutical service needed to be improved. The development models of online drugstores in the United Kingdom ，the United States and Germany could be referred. According to the current situation of online drugstores in China ， combined with the development mode and operation strategy in foreign countries ，it is suggested to improve relevant laws and regulations，and strengthen legal support ；strengthen the government supervision to ensure drug safety ；use the industrial power to standardize medicine operation behavior ；set up the third part trading platform to promote medical insurance payment.

OBJECTIVETo identify and characterize laryngeal cancer related novel genes located on chromosome 6q25.

METHODSElectric hybridization was performed in human genome database using EST (expression sequence tag) as probe. Novel genes were deduced by software from positive DNA clones and their cDNAs were amplified by RT-PCR using primers designed according to the sequence of the putative genes.

RESULTSA novel gene was cloned successfully. The full length of this gene was about 21 kb. It contained two exons and produced a 1006 bp transcript coding a protein with 235 amino acid residues. It's 5'flanking sequence contained two binding sites of oncoprotein c-Myc, thus it was named MTLC (c-Myc target from laryngeal cancer cells). Homologous assay showed that MTLC exhibited little overall homology to known human proteins but it exhibited good overall homology to mouse MT-MC1 protein with an identity of 78%. The primary structure of MTLC protein contained a nuclear location signal motif, but it did not have other conserved domains. The results of subcellular location experiment showed that MTLC expressed in nuclei of human hepatocellular carcinoma cell line Bel7402 cells, while a wide distribution of MTLC in various tissues was demonstrated by Northern blotting.

CONCLUSIONMTLC may play an important role as a target gene of c-Myc and as a transcription factor in keeping the normal physiological process of cells.

OBJECTIVETo investigate the role of transglutaminase 3 (TGM3) gene in laryngeal carcinogenesis.

METHODSThe authors detected the deletion indirectly through loss of heterozygosity (LOH) analysis at DNA level using 4 STR primers within and near TGM3 gene in 72 cases, and detected the differential expression of TGM3 gene in 8 cases of paired normal and cancerous tissue of laryngeal carcinoma by Northern blot.

RESULTSLOH was found existing in all of the microsatellite loci, and the LOH frequencies were 25.76%, 20.00%, 38.10% and 18.75% at D20S17, D20S607, D20S99 and D20S841 respectively; LOH concerning at least one polymorphism locus accounted for 61.11%. No correlation of clinical stage, lymph node metastasis and differentiation with the LOH of TGM3 gene was observed, P>0.05. TGM3 gene expressed significantly higher in normal tissues than in paired cancerous tissues.

CONCLUSIONTGM3 gene might play an important role in laryngeal carcinogenesis and further researches will be needed to clarify the possible mechanisms.
