Objective:To study the effect of the cytokines, tumor necrosis factor-?(TNF-?), interferon-?(IFN-?), interferon-?(IFN-?), platelet-derived growth factor BB(PDGF-BB), basic fibroblast growth factor(bFGF),on promoter activity of human transforming growth factor-?1(TGF-?1) gene.Methods:A construct of phTGF2.14 containing sequence from -1 328 bp to +812 bp of human TGF-?1 gene,linking with chloramphenicol acetyltransferase(CAT) as reporter gene,was transiently transfected into rat hepatic stellate cell line nFSC. The cells were subsequently treated with TNF-?,IFN-?,IFN-?,PDGF-BB,bFGF, and the CAT activity was assessed 48 hours after stimulation with each cytokines.Results:TNF-? of 10 ng/ml can increased the CAT activity of phTGF2.14 to 3.24 fold compared to control. IFN-? and IFN-? at 1 000 U/ml decreased CAT activity to (42?12)% and (58?6)% of control respectively.PDGF-BB,bFGF of 10 ng/ml had no effect on promoter activity of human TGF-?1 gene;Combined application of IFN-?,IFN-? and TNF-?,the promoter TGF-?1 gene were 1.32 and 1.46 fold compared with control,respectively.Conclusion:These data indicate that TNF-? can increase the promoter activity of human TGF-?1 gene, but IFN-?,IFN? can downregulate the CAT activites of phTGF2.14, and IFN-?,IFN-? can interdict the upregulate effect of TNF-? on phTGF2.14. We did not find PDGF-BB,bFGF have any effect on TGF-?1 promoter. These provided an essential evidence for study the interaction mechanism of cytokines in fibrogenisis diseases.

BACKGROUND:Currently, the enzymatic digestion combined with magnetic activated cel sorting for isolating microvascular endothelial cel s are cumbersome and do harm to cel s. Therefore, how to simplify the isolation and culture of human dermal microvascular endothelial cel s to obtain highly purified endothelial cel s in vitro becomes a hotspot.
OBJECTIVE:To explore a simple and effective cultivation method of microvascular endothelial cel s from diabetic patient skins in vitro, and to detect the cel growth.
METHODS:Diabetic patients with chronic foot wounds after amputation were enrol ed to col ect the limb proximal skin and topical skin around the wound superficial dermal tissue. Human dermal microvascular endothelial cel s were obtained using adherent method and trypsin method, fol oewd by purified utilizing trypsin digestion and repeated attachment method when passage culture.
RESULTS AND CONCLUSION:Human dermal microvascular endothelial cells were obtained successfully, Primary cultured endothelial cells completely adhered to the wall at 24 hours, entered the logarithmic phase at the 10th day, and the cell concentration reached 80%at the 12th-13th day. While the passage cells grew more actively than primary cells, and fully covered the bottom in a“cobblestone”arrangement after 5-7 days of culture. Immunohistochemical staining showed that cultured cells were positive for FVIII and CD31-associated antigens with 100%positive rate. MTT assay showed that cell growth curves of 2, 4, and 5 generations of dermal microvascular endothelial presented the invertedSshape. These results suggest that abundant highly purified human dermal microvascular endothelial cells can be obtained through the adherent method and a small amount of short-term trypsin method.

OBJECTIVETo evaluate the radical effect and postoperative anal function of total mesorectum excision (TME) combined with different intersphincter resection (ISR) in treatment of T1 and T2 stage ultra-low rectal cancer.
METHODSClinical data of 102 T1 and T2 stage ultra-low colorectal cancer patients who received TME combined with different ISR from January 2004 to December 2013 in our department, including 33 cases of complete internal anal sphincter excision ISR (complete ISR group), 39 cases of partial internal anal sphincter excision ISR (partial ISR), 30 cases of partial dentate line reservation ISR (dentate line group). All the operation procedures followed the principles of TME. Radical conditions were compared and similarly, postoperative anal function was evaluated by Williams classification standard among 3 groups.
RESULTSThe general information, such as gender, age, BMI, maximum diameter of tumor, distance of tumor edge to dentate line, TNM staging, degree of differentiation among 3 groups had no statistically significant differences (all P>0.05). The operation time, intraoperative blood loss, length of removed intestinal canal, resection margin, the harvested number of lymph nodes, and postoperative complications among 3 groups also had no statistically significant differences (all P>0.05). Twelve months after surgery, good anal function rate in part ISR group and dentate line group was 100%, significantly better than that in complete ISR group (75.8%) with significant difference (χ2=4.654, P=0.015).
CONCLUSIONTME combined with ISR surgery in treatment of T1 and T2 stage ultra-low rectal cancer is safe and effective, which, as far as possible to preserve partial internal sphincter and dentate line on the premise of the guarantee of radical condition, can help to improve the postoperative anal function.

OBJECTIVETo compare the effect of rapid rehabilitation surgery (FTS) with the traditional operation method on postoperative immune function recovery, inflammatory reaction and the clinical efficacy in elderly patients with colorectal cancer.
METHODSA total of 144 elderly patients (older than 65 years) diagnosed as colorectal cancer in our department from February 2010 to August 2013 were prospectively enrolled in the study. According to the order of admission, patients were randomly divided into the fast track surgery group (72 cases, study group), and the traditional operation group (72 cases, control group). Preoperative and postoperative T cell subsets, inflammatory index and organ functional parameters were detected and compared.
RESULTBasal clinical data of the two groups had no significant differences (all P>0.05). Three days after operation, CD4+ and CD8+ in both groups increased compared to preoperative levels (P<0.05), while the study group had greater increasing amplitude of CD4+ (t=1.685, P=0.003), and lower CD8+(t=1.145, P=0.005) than the control group. CD4+/CD8+ increased in the study group compared to preoperation and significantly higher than that in the control group (P=0.001). Inflammatory stress indexes were significantly increased, while study group had smaller amplitude than the control group. Serum creatinine, B-natriuretic peptide and Troponin-T increased after operation, while the study group had smaller amplitude than the control group (P<0.05). The study group showed faster resumption of oral intake, quicker bowel function return, time to first defecation, hospital stay, lower incidences of nausea, vomiting, incision infection, and less cost of hospitalization. All the differences were significant (all P<0.05).
CONCLUSIONFast track surgery can effectively protect the perioperative organ function, increase postoperative immune function, decrease inflammation stress reaction, reduce perioperative morbidity of complication, improve efficacy for elderly colorectal cancer patients.
