Objective:To investigate frequencies of microsatellite instability(MSI)and loss of heterozygosity(LOH)in renal ceil carcinoma(RCC),and to discuss the relationship of clinicopathological characteristics of RCC with MSI and LOH. Methods:Twelve microsatellite markers located at chromosomes 3p,9p and 14q were selected to investigate microsatellite alterations(MSI and LOH)in 31 RCC specimens and their paired metastasis specimens by polymerase chain reaction- polyacrylamide gel elect rophoresis-ethylene dibromide(PCR-PAGE-EB)staining and sequencing.Results:The frequency of MSI could reached 61.3% and that of LOH could reach 54.8%.The highest frequency of MSI was at locus of D9S168(32.3%);the highest frequency of LOH was at locus of D3S1289(21.4%).No correlation was found between MSI or LOH and the patients' age,sex,pathology type and metastastis,except that MSI was correlated with TNM stage of RCC(P

When looking back to the literature regarding insomnia, it is believed that "disharmony of stomach leads to insomnia" is an important mechanism for the attack of insomnia. This theory is widely accepted in clinical practices by ancient and modern acupuncturists, thus the method treating insomnia from the stomach is developed. But deeper research on its mechanism is still lacking. Through correlation between stomach meridian and heart meridian, spleen and stomach being the pivot of rise and decline of qi movement and yin-yang and being the pivot of five zang-viscera housing spirit, modern abdomen-brain theory and experimental research, the mechanism of treating insomnia from the stomach is discussed in this paper, so as to be better to guide clinical acupoint-selection and treatment.

Signal transducer and activator of transcription 3 (STAT3) is an important regulatory factor of cell proliferation and metastasis, involved in the occurrence and development of a variety of malignant tumors, and it is one of the hot spots in the research of targeted anti-tumor drugs. Our group screened a novel benzobis (imidazole) structure small molecule compound LZJ541 through the screening model of Janus kinase (JAK)/STAT3 pathway inhibitors, which has definite STAT3 inhibitory activity. We examined the effect of LZJ541 on the proliferation of HepG2 and PC-3 cells by MTT assay in vitro, detected the effect of LZJ541 on the expression of STAT3-related proteins in HepG2 cells by Western blot, and measured the effect of LZJ541 on the apoptosis and cell cycle arrest of HepG2 cells via flow cytometry. The results indicated that LZJ541 significantly inhibited the activation of STAT3 signaling pathway and restrained the proliferation of HepG2 cells. Its half maximal inhibitory concentration (IC₅₀) was 13.8 μmol·L^-1, which was much lower than that of PC-3 cells (with low STAT3 expression, IC₅₀: 41.99 μmol·L^-1), LZJ541 can also inhibit the phosphorylation of STAT3 in HepG2 cells, thereby inducing apoptosis and cycle arrest and then exerting anti-tumor effects. In conclusion, LZJ541 has a certain anti-tumor effect in vitro, which provides an experimental basis for the development of new STAT3-targeted anti-tumor drugs around this kind of compounds.

OBJECTIVEThe SSR information in the transcriptome of Erigeron breviscapus was analyzed in this study, in order to further develop new functional genes SSR markers laid a solid foundation.

METHODSSR loci were searched in all of 52,060 unigenes by using est_timmer. Perl program and SSR primers were designed by Primer3. Furthermore, 36 pairs of primers were randomly selected for the polymorphism analysis on 13 Erigeron breviscapus plants collected from different places.

RESULTA total of 3639 SSRs were found in the transcriptome of Erigeron breviscapus, distributed in 3260 unigenes with the distribution frequency of 6.99%. Di-nucleotide repeat was the main type, account for as much as 34.41% of all SSRs, followed by mono-nucleotide (31.41%) and tri-nucleotide repeat motif (28.08%). The di-nucleotide repeat motifs of AT/AT and AC/GT were the predominant repeat types (28.71%). The tri-nucleotide repeat motifs of AAT/AT was the predominant repeat types (7.94%). For validation the availability of those SSR primers, we randomly selected 36 pairs of primers for PCR amplification. Among them, 34 pair primers (94.44%) produced clear and reproductive bands, 19 pair primers showed polymorphism (52.78%), and 13 Erigeron breviscapus plants were divided into 2 groups.

CONCLUSIONThere are numerous SSRs in Erigeron breviscapus transcriptome with high frequency and various types, this will provide abundant candidate molecular markers for genetic diversity study and genetic map in this plant.
