AIM:To explore the effects of the combined use of human telomerase reverse transcriptase (hTERT) gene antisense oligodeoxynucleotide (ASODN) and cisplatin on apoptosis of HL-60 cells. METHODS:PCR-ELISA was used to determine telomerase activity in HL-60 cells untreated or treated with ASODN, the expression levels of hTERT protein were assayed by immunofluorescence using fluoresce isothiocyanate (FITC) label. Apoptosis was detected by DNA electrophoresis and flow cytomertric cell cycle analysis. RESULTS:The expression levels of hTERT protein and telomerase activity in HL-60 cells treated with ASODN were shown to decrease with time, the DNA fragments were obviously found and the percentage of apoptosis cells was significantly enhanced in HL-60 cells with the combined use of hTERT ASODN and cisplatin compared with the combined use of hTERT sense oligodeoxynucleotide and cisplatin or cisplatin alone, respectively. CONCLUSION:Inhibition of telomerase activity by hTERT ASODN increases the cisplatin-induced apoptosis of HL-60 cells.

As the largest protective barrier of the body,gastrointestinal tract helps the organism resist the invasion and attacks of harmful substances from the outside world.There are three kinds of protective barriers:mechanical barrier,biotical barrier,and immune barrier.In recent years,increasing researches indicate the importance of gastrointestinal immune barrier and the important immunologic mechanism of enteral nutrition in improving the clinical outcome.This article reviews the effect of gut immunity in the improvement of clinical outcome by enteral nutrition.

Objective To investigate the biological effect of GM-CSF on splenic dentritic cells (DCs)when used to treat severe sepsis and the influence on the prognosis.Methods All 160 male Kunming mice were randomly(random number)divided into four groups:control group(n =50),the mice didnt receive special treatment; CLP group(n =42),the mice underwent cecal ligation and puncture;conventional treatment group(n =34),the mice received intraperitoneal injection of 5 mg/kg ceftriaxone at 12,24,36,48,60,72 and 84 h after surgery; GM-CSF treatment group(n =34),the mice received hypodermic injection of 20 μg/kg GM-CSF besides ceftriaxone at 12,36,60,and 84 h after surgery.The mice were sacrificed at 0,12,24,48 and 72 h after CLP by cervical dislocation.The amount of splenic DCs and apoptosis rate were measured by flow cytometry,and the serum concentrations of IL-12 were detected by ELISA in each group.Meanwhile the survival prognosis was observed at 96 h.Results At every time point,the apoptosis of splenic DCs increased and the amount markedly reduced in severe sepsis(P ＜0.05),the serum concentration of IL-12 increased on an one-way curve type(P ＜0.05).The treatment of cephalosporin exacerbated the loss of DCs(P ＜ 0.05),while hadnt any effect on IL-12(P ＞ 0.05).GMCSF treatment increased the amount of DCs(P ＜ 0.05),and decreased IL-12 concentrations(P ＜ 0.05).The OR of GM-CSF was 0.079 computed by Logist regression analysis.Conclusions GM-CSF treatment severe sepsis can increase the amount of splenic DCs,decrease serum levels of IL-12,and improve prognosis.

Objective To study the value of imaging characters in diagnosing mediastinal tumors.Methods X-ray and CT findings of pathologically proved mediastinal tumors in 58 cases were analysed,the findings enabling qualitative diagnosis were recommended. Results There were 40 cases of anterior mediastinal tumors including intrathoracic thyroid tumors [n=32,5 tyroid carcinomas and 1 thyroid cyst ,thymomas (n=3) and teratomas (n=5, 3 cases ruptured)]. All the other 18 cases in posterior mediastinum were neurogenic tumors.Conclusion Based on the combination of the mediastinal compartment knowledge, X-ray and CT findings of the tumors and the clinical information, the qualitative diagnosis of mediastinal tumors will be characterized correctly.

Objective To study the effects of nitric oxide (NO) on the growth and metastasis of tumor.Methods The literatures of recent years were reviewed.Results NO had double effects on the growth and metastasis of tumor. NO promoted the growth and metastasis by regulating the expression of tumor proliferation gene and inducing tumor angiogenesis. On the other hand, NO had antitumor effects by interfering with the metabolism of tumor cells, inducing the damage of DNA, forming high toxic free radical, inducing apoptosis of tumor cells and mediating the antitumor action of endothelial cells and macrophages.Conclusion Selective blockage or induction of synthesis of NO may be a new way for tumor therapy.

Objective:To determine whether the bcl-2 antisense oligonucleotide (ASODN) can increase the sensitivity of NCI-H460 cell lines to docetaxel or radiation. Methods: Docetaxel in combination with bcl-2 ASODN or non-sense oligonucleotide (NSODN) was used to treat NCI-H460 cells, and then IC_~50 of docetaxel against NCI-H460 cells was determined with MTT method. In radiation group, NCI-H460 cells were divided into pure radiation, radiation plus bcl-2 ASODN, and radiation plus NSODN groups. The inhibition rates of cell growth were assayed by MTT, and the expression levels of Bcl-2 protein were assayed by immunofluorescence. Results: IC_~50 in bcl-2 ASODN plus docetaxel, pure docetaxel and NSODN plus docetaxel groups was (0.101?0.009) ?mol/L,(0.183?0.018)?mol/L, and (0.179?0.016)?mol/L, respectively. The differences between the first group and the latter 2 groups were significant (P
