On the basis of the Uncaria transcriptome, specific primers were designed for UrSTR. The full-length cDNA of UrSTR (GeneBank: OL310251) was 1 541 bp, encoding 345 amino acid residues, and the promoter region sequence of UrSTR (GeneBank: OL310252) was 1 179 bp. Phylogenetic tree is revealed that UrSTR had a closest relationship with STR from Ophiorrhiza pumila and Ophiorrhiza japonica. Localization of UrSTR protein is revealed located in the vacuole membrane. Plant-care analysis indicated that the promoter region sequence of UrSTR, covering multiple light, stress and hormone-response cis-regulatory elements, and verified transcriptional activity. The results of SDS-PAGE show that pET-28a-UrSTR recombinant protein was successfully expressed, and the size was anticipated. The UrSTR prokaryotic expression system needs to be optimized in the later stage. The research lays the foundation for further purification to study its structure and functional characterization of the UrSTR protein.

Background and purpose:Five-year survival rate of post-operation patients with non-small cell lung cancer(NSCLC)is less than 40%.Treatments after recurrence are difficult.Our study aimed to evaluate the efficacy of pemetrexed on postoperative recurrence of NSCLC.Methods:From Jan.2006 to Sep.2008,40 NSCLC with postoperative recurrence were observed.All patients had received pemetrexed(ALIMTA)500 mg/m2 or carboplatin eonbined.Results:Among the 40 patients,partial response in 10 patients(25.00%),stable disease in 19 patients(47.50%),progressive disease in 11 patients(27.50%).The total response rate was 25.00%and clinical benefit control rate was 72.50%.Pemetrexed had significantly better disease control rate in female than in male (9 1.30% vs 47.06%,P=0.034),in adenocarcinoma patients than in non-adenocarcinoma's(87.10% vs 22.22%,P=0.001).Median overall survival time(MST)was 10.70 months.Progression-free survival time(PFS)was 5.18 months.Adenocarcinoma patients had longer PFS than non-adenocarcinoma patients.Conclusion:Pemetrexed demonstrates significant antitumor activity and good tolerance in these patients.

Objective To screen microRNAs(miRNAs)related to early mycosis fungoides(MF). Methods A high?throughput miRNA PCR array was used to determine miRNA expression profiles in skin lesions of 6 patients with early MF (early MF group) and 6 patients with lichen planus (control group), followed by screening of differentially expressed miRNAs between the two groups. Then, real?time fluorescence?based quantitative PCR(RT?qPCR)was performed to verify the differentially expressed miRNAs in lesional specimens from 13 patients with early MF and 13 patients with eczema or lichen planus, as well as in Myla cells and normal human T?lymphocytes. Results The high?throughput miRNA PCR array showed that the expressions of hsa?miR?378a?5p, hsa?miR?107 and hsa?miR?302c?3p were significantly higher in the early MF group than in the control group(all P<0.05). For skin lesions, the results from RT?qPCR were similar to those from the miRNA array assay. Compared with normal human peripheral blood T?lymphocytes, Myla cells showed significantly increased expressions of hsa?miR?378a?5p and hsa?miR?107, which was consistent with the results from the miRNA array assay. However, no significant difference was observed in the expression of hsa?miR?302c?3p between the two kinds of cells. Conclusion MiRNA expression profiles in early MF are different from those in inflammatory skin diseases.

AIM: To investigate the effects and mechanism of enalapril on nephritis of diabetic mice. METHODS: Diabetes was induced by injection of streptozotocin after uninephrectomy. Rats were randomly divided into three groups: control, diabetes, diabetes treated with enalapril (10 mg?kg~-1 ?d~-1 by gavage). 8 weeks after STZ injection, urine albumin excretion rate (AER) were measured, and glomerular morphology were observed by light microscopy. The levels of malonyldialdehyde (MDA) in renal tissue and urine as well as activities of superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GSH-PX) in renal tissue were determined. Immunohistochemistry for ED-1 (macrophage marker), monocyte chemoattractant protein-1 (MCP-1) and intercellular adhesion molecule-1 (ICAM-1) were performed by streptavidin-biotin complex (SABC) technique. RESULTS: Increased kidney weight, ratio of kidney weight to body weight, AER and expansion of mesangial as well as tuft areas on histological examination of the kidney were significantly attenuated by the treatment of enalapril (P

OBJECTIVE To explore the effect and mechanisms of LW-AFC,a new formula derived from Liuwei Dihuang decoction,on chronic unpredictable mild stress(CUMS)-induced mood and cogni-tion impairment in mice. METHODS C57BL/6J mice were randomly placed into seven groups (n=10):normal control group,CUMS group,Fluoxetine(10 mg·kg-1,once per day)group,Liuwei Dihuang de-coction group(LW,10 g·kg-1,once per day),and LW-AFC(0.8 g·kg-1,1.6 g·kg-1,3.2 g·kg-1,once per day) group. The stressed group was given CUMS for 4 weeks to set up a chronic multiple-stressed model.LW and LW-AFC was oral administered a week prior to CUMS and until the end of the study(a total of 35 d),while fluoxetine was administrated orally for 4 weeks.The anxiety behavior was analyzed using the open field test(OFT)and elevated plus maze test(EPM).The depression behavior was ana-lyzed using the sucrose preference test (SPT) and forced swimming test (FST). Spatial cognition was evaluated using Morris water maze (MWM) test and working memory was evaluated using new object recognition test(NORT). RESULTS CUMS for 28 d increased depressive-and anxiety-like behaviors. LW-AFC (1.6 g·kg-1) significantly increased the numbers of entries into the open arm and time in the open arm of CUMS mice (P<0.05). LW-AFC (3.2 g·kg-1) increased sucrose consumption and de-creased the immobility time of FST (P<0.01) of CUMS mice. The MWM test showed that spatial learning andmemory in CUMS mice were remarkably affected relative to controls,whereas LW-AFC(3.2 g·kg-1)im-proves cognitive functions(P<0.05).CONCLUSION The mood and theability of learning and memory of thestressed group can be affected after exposure to CUS.Oral administration of LW-AFC significant-ly improved CUMS-induced impairments of mood and cognition in mice.

Objective To determine the effect of mild hypothermia on neonatal piglet cardiac hemodynamic function after hypoxia-ischemia (HI).Method Twenty five 7-day-old piglets were used for hypoxic ischemic brain damage (HIBD) model by the method of temporary occlusion of the bilateral carotid arteries and followed by mechanical ventilation with low concentration of oxygen (FiO_2=6%) for 30 minutes.The piglets were randomly divided into three groups:group A (normothermia with body temperature to 39℃,n=9),group B (body temperature to 36℃for 72 hours,n=8),and group C (body temperature to 34℃for 72 hours,n=8).Mild hypothermia was initiated at 4 hours after HI,the systolic and diastole function were evaluated by Doppler echocardiography at pre-HI,post-Hi 4 hours and post-HI 72 hours.Results There were no significant differences in left ventrieular ejection time/left ventrieular ejection time (LPEP/LVEF),right ventricular ejection acceleration time/right ventricular ejection time (RACT/RVET) and CO at post-HI with hypothermia 72 hours in three groups,but the heart rate decreased in B and group C group.Compared with nonnothermia,mild hypothermia treatment showed no significant differences in MAP,LPEP/LVET,RACT/RVET,CO,SV at post-HI with hypothermia 72 hours.Conclusions Body temperature decreased by 3～5℃for 72 hours will not aggravate hemodynamic abnormity.
