The mechanism of the development of sporadic renal cell carcinomas is complicated,which is different from that of hereditary renal-cell carcinoma.Genetics abnormality such as loss of 3p,VHLgene mutations may help differentiate pathological subtype of renal cell carcinoma and some gene markers may be useful predictors for prognosis.The current status of genetic study in renal cell carcinomas is reviewed in this article.

OBJECTIVE: To explore the correlation between postmortem interval (PMI) and five RNA markers of rat's skin--β-actin, glyceraldehyde-3-phosphate dehydrogenase (GAPDH), 18S ribosomal RNA(18S rRNA), 5S ribosomal RNA (5S rRNA), and microRNA-203 (miR-203), at different temperatures. METHODS: Eighteen SD rats were randomly divided into three environmental temperature groups: 4 °C, 15 °C and 35 °C, respectively. Skin samples were taken at 11 time points from 0 h to 120 h post-mortem. The total RNA was extracted from the skin samples and the five RNA levels were detected by real-time fluorescent quantitative PCR. Proper internal reference was selected by geNorm software. Regression analysis of the RNA markers was conducted by GraphPad software. RESULTS: 5S rRNA and miR-203 were most suitable internal references. A good linear relationship between PMI and RNA levels (β-actin and GAPDH) was observed in two groups (4 °C and 15 °C), whereas the S type curve relationship between the expression levels of the two markers (β-actin and GAPDH) and PMI was observed in the 35 °C group. The partial linear relationship between 18S rRNA and PMI was observed in the groups (15 °C and 35 °C). CONCLUSION Skin could be a suitable material for extracting RNA. The RNA expression levels of β-actin and GAPDH correlate well with PMI, and these RNA markers of skin tissue could be additional indice for the estimation of PMI.

More than ten bacteriophage of E.coli were isolated from the soil and the dung of the fowl-run, then three of named bacteriophage A, C, D which lysis E.coli virulently were selected to investigate biological characterizations. The results showed that high activities were obtained after the phages incubated at 50℃ for 1 h or 60℃ for 30 min. The phages could be alive at the range of pH from 4 to 12, Ca 2+ or Mg 2+ added to the medium could stimulate the lysis of phages. However, the formation of the plaque could be inhibited obviously by adding sodium citrate to the medium.

Introduction: Tuberculosis (TB) in internal migrants is one of three threats for TB control in China. To address this threat, a project was launched in eight of the 19 districts of Shanghai in 2007 to provide transportation subsidies and living allowances for all migrant TB cases. This study aims to determine if this project contributed to improved TB control outcomes among migrants in urban Shanghai. Methods: This was a community intervention study. The data were derived from the TB Management Information System in three project districts and three non-project districts in Shanghai between 2006 and 2010. The impact of the project was estimated in a difference-in–difference (DID) analysis framework, and a multivariable binary logistic regression analysis. Results: A total of 1872 pulmonary TB (PTB) cases in internal migrants were included in the study. The treatment success rate (TSR) for migrant smear-positive cases in project districts increased from 59.9% in 2006 to 87.6% in 2010 (P < 0.001). The crude DID improvement of TSR was 18.9%. There was an increased probability of TSR in the project group before and after the project intervention period (coefficient = 1.156, odds ratio = 3.178, 95% confidence interval: 1.305–7.736, P = 0.011). Conclusion: The study showed the project could improve treatment success in migrant PTB cases. This was a short-term programme using special financial subsidies for all migrant PTB cases. It is recommended that project funds be continuously invested by governments with particular focus on the more vulnerable PTB cases among migrants.

OBJECTIVETo observe the effect of emodin on motility signal transduction and calcium ion in colonic smooth muscle cells (SMC) in rats with bacterial peritonitis caused multiple organ dysfunction syndrome (MODS).

METHODSObservation was conducted in colon of MODS model rats on (1) effects of emodin on the contraction of muscular strip and cells of colonic smooth muscle, and influences of specific myoglobulin light chain kinase inhibitor (ML-7) and selective proteinkinase C inhibitor (Calphostin C) on these effects; and (2) effect of emodin on calcium ion in SMC.

RESULTSEmodin could directly contract the muscular strip and cells of smooth muscle; ML-7 and Calphostine could inhibit these contractile action to some extent. Under MODS condition, emodin could still increase the intracellular calcium ion concentration; this effect could be inhibited by heparin (inosamine triphosphate receptor inhibitor IP3 and ryanodine receptor inhibitor in MODS model but the calcium chelator EGTA and nifedipine (the specific cell membrane voltage dependent calcium channel blocker) showed no influence on it.

CONCLUSIONEmodin could directly contract the colonic smooth muscle in MODS model rats, which is mediated by raise the signal path MLCK of calcium ion and the PKCa path for increase calcium sensibility. The mechanism of increasing calcium ion is mainly through IP3 and RyR the two calcium ion channel receptor in the sarcoplasm.

This study aims to analyse the value of CODEHOP RT-PCR in the detection of Flavivirus. According to the amino acid sequences of polyproteins of different flaviviruses published in GenBank, a pair of primers was designed using the CODEHOP method. One-step RT-PCR was used to detect Japanese encephalitis virus strain JEV1201, Dengue virus strain JKD001, and yellow fever virus vaccine YV6161. BLAST analysis and phylogenetic analysis were performed after the RT-PCR products of nucleocapsid genes were sequenced. The results showed that this method could amplify Flavivirus specifically, and the size and sequence of the target fragment accorded with the anticipated result. JEV1201 had the highest homology to Japanese encephalitis virus strain YL2009-4/YC2009-3, belonging to the branch of the phylogenetic tree of Japanese encephalitis virus strains. JKD001 had the highest homology to Dengue virus strain DENV-2/ID/1022DN/1975, belonging to the branch of the phylogenetic tree of Dengue virus strains. YV6161 had the highest homology to Yellow fever virus strain 17D, belonging to the branch of the phylogenetic tree of Yellow fever virus strains. In conclusion, the method of CODEHOP RT-PCR can be effectively used to detect, identify, and phylogenetically analyse Flavivirus.
