Objective To investigate the regulative effect of cyclooxygenase-2 (COX-2) 3'-UTR in HT29 colon cancer cells. Methods Total RNA was extracted from HT29 colon cancer cells and used as a template to amplify COX-2 gene by reverse transcription polymerase chain reaction. Using PCR technique to construct a series of luciferase reporter gene expression vectors containing various regions of the 3'-UTR of COX-2 (including the whole gene region, gene region between 1 to 156 bp, gene region between 1 to 347 bp, gene region between 1 to 1006 bp, gene region between 156 to 347 bp and gene region between 157 to 2217 bp). These reporter gene expression vectors and pRL-SV40 were co-transfected in HT29 colon cancer cells by Lipofectamine 2000. The relative luciferase activity of the HT29 colon cancer cells was tested. All data were analyzed via t test. Results The luciferase activity was reduced by 70.4%, 37.4%, 64.8% and 24.2% in HT29 colon cancer cells transfected with the whole COX-2 gene region, gene region between 1 to 156 bp, gene region between 1 to 347 bp and gene region between 156 to 347 bp, respectively (t = 6.13, 7.73, 9.75, 3.92, P < 0.05). No obvious changes of luciferase activity were observed in HT29 colon cancer cells transfected with gene regions between 1 to 1006 bp and between 157 to 2217 bp (t = 0.13, 0.01, P > 0.05). Conclusions A region between 156-347 bp in the 3'-UTR of COX-2 has been found which can down-regulate the expression of COX-2 with the cooperation of the ARE element. The 3'-UTR of COX-2 contains several control elements that regulate the expression of COX-2 in colon cancer cells.

The alterations in electron transport were studied in the myocardial mitochondria of rats with hemorrhagjc shock. Hemorrhagic shock model was induced by a modified Wigger procedure. Mitochondria were obtained by differential centrifugation. Succinate-, and NADH-respiratory chains were assayed by polarographically and spectrophotometrically in isolated myocardial mitochondria. The results showed that hemorrhagic shock led to progressive decrease in the enzymatic activities of two respiratory chains. The activities of Succinate-Co. Q reductase, Succinate-Cyt. C reductase, NADH-Co. Q reductase, NADH-Cty. C reductase and cytochrome oxidase were remarkably lower in shock 3 h group than those in the shamoperated. This implies that there is not only low-flow hypoxia, but inability to utilizer oxygen in the myocardial mitochondria

Objective To establish a stable model of rat orthotopic left lung transplantation using direct suture of vessels and bronchi. Methods Ten Sprague Dawley (SD) rats weighted 250 to 350 g were used as lung donors and recipients respectively. Airway and pulmonary vessels were reconstructed microsurgically using continuous running suture technique. Survival time were recorded and donor lungs were checked by autopsy. Results All 10 rats received left lung transplantation were weaned from ventilator successfully. Both of cold ischemia time and warm ischemia time were about 40 minutes. The total procedure took about 130 minutes. Autopsy was used to check the patency of anastomotic sites. No thrombosis or air leak was found. Conclusions Direct microsurgical surture can be used to establish an experimental model of orthotopic left allograft lung transplantation in rats. This method is proved to be stable, reliable and similar to clinical practices.

OBJECTIVETo compare the differences in the therapeutic effect on irritable bowel syndrome (IBS) between acupuncture at Tianshu (ST 25) and Dachangshu (BL 25) and western medication with Trimebutine Maleate.

METHODSForty cases were divided randomly into an acupuncture group and a western medication group, 20 cases in each one. In acupuncture group, acupuncture was applied to Tianshu (ST 25) and Dachangshu (BL 25). Ziwu Daojiu needling technique was adopted, once daily. In western medication group, Trimebutine Maleate capsule was administered, 2 capsules in each time, 3 times per day. The assessment on the therapeutic effect was performed in 4 weeks of treatment in two groups.

RESULTSAs compared with those before treatment, the time of abdominal pain, the frequency of abdominal pain, the morbidity of abnormal stool appearance, the morbidity of defecation abnormality, the morbidity of mucus stool and the score of bloating or abdominal pain on bowel movement were all reduced after treatment in two groups (all P < 0.01). The results in acupuncture group were much more significant than those in western medication group (the total score: 16.70 +/- 2.40 vs 15.70 +/- 3.01, P < 0.01). The total effective rate in acupuncture group was 95.0% (19/20), which was superior to that of 70.0% (14/20) in western medication group (P < 0.05).

CONCLUSIONAcupuncture at Tianshu (ST 25) and Dachangshu (BL 25) may remarkably relieve the clinical symptoms of IBS and its efficacy is superior to that of oral medication with Trimebutine Maleate.

Objective To investigate the value of ultrasound-guided diffuse optical tomography (US-guided DOT) to predict clinical efficacy of breast cancer neoadjuvant chemotherapy (NAC).Methods Eighty-eight breast cancer patients with 93 lesions were included.Pre-and post-last chemotherapy,the size,total hemoglobin concentration (THC) of each lesion were measured by ultrasonography (US) and US-guided DOT.Based on the guidelines to evaluate the response to treatment in solid tumors,the lesions of treated breast cancer patients were divided into 4 types of responses to NAC:complete response (CR),partial response (PR),stable disease (SD),and progressive disease (PD).Efficient groups include CR and PR groups.Results As expected,no significant difference was found in size and THC for untreated lesions (all P ＞0.05).However,for the treated lesions(P =0.001),THC,pre-vs post-treatment size changes (△Size％) (P =0.002) and THC changes (△THC％) (P ＜0.001) were significantly varied among CR,PR,SD,PD groups.When compared with pre-treated,tumor sizes after treatment were changed significantly in all CR(P ＜0.001),PR(P ＜0.001),SD (P =0.023) and PD (P =0.001),while significant change of THC was only found in CR(P ＜0.001),PR(P ＜0.001) and SD (P =0.002).When △THC％ =23.9％ as the threshold for prediction of NAC efficiency,the area under the curve of ROC was 0.75,and the sensitivity was 73.7％,specificity was 76.5 ％,positive predictive value was 93.3 ％,negative predictive value was 39.4％,accuracy was 74.2％.Conclusions △size％ changes in consistent with △THC％ among the intergroups,but their changes levels are different,the highest change percent appears in CR,gradually decreased in PR,SD groups.△THC％ will contribute to predict preoperative clinical NAC efficacy.

This study was purposed to characterize the genomic distribution of the binding sites for AML1-ETO fusion protein on chromosome 2, 9 and 19, and to further gain insights into the characteristics of transcriptional regulation by AML1-ETO in acute myeloid leukemia so as to provide theoretical basis for the development of targeted therapy and optimization for treatment. Chromatin immunoprecipitation (ChIP) coupled with high density tiling arrays (chip), also known as ChIP-chip, was utilized in this study. ChIP-DNA enriched by an anti-ETO antibody and total genomic DNA of Kasumi cells were hybridized to tiling arrays, tiled through chromosome 2, 9 and 19. The ChIP enriched regions were identified using a model based analytical tool (MAT). Genomic distribution of the ChIP regions was analyzed using publicly available CEAS web server. The Gene Ontology (GO) enrichment analysis was performed to excavated the biological significance. The results indicated that a total of 588 enriched regions were identified on chromosome 2, 9 and 19 by the anti-ETO antibody. A number of the identified regions were located within enhancers (48.86%) or introns (37.35%), much smaller fractions were within proximal promoters (5.96%) or exons (5.49%). Functional enrichment analysis showed that cell proliferation and signal transduction biological pathways were enriched in potential genes of AML-ETO. It is concluded that half of the AML1-ETO binding sites are located within known transcriptional regulatory regions (promoter, 5' UTR and enhancer), while almost another half were within the sequences which were not previously reported as regulatory regions. The potential target molecular network of AML1-ETO is involved in several essential biological processes.
