0.05). All of the indexes in control group were lower on post-operative day 7 than those of pre-operation. The levels of pre-albumin,transferrin, fibronectin, IgG,IgM, CD~+_3, CD~+_4 T cells and nitrogen balance in the study group were significantly higher than those of control group.Negative nitrogen balance began to be positive in the study group on the post-operative day 7. However, the nitrogen balance in the control group was still negative on the post-operative day 10. The duration of hospitalization in the r-hGH group was shorter than that of the control group. The 1-year, 2-year and 3-year survival rates and recurrence rate were not different between two groups.(Conclusions) The post-operative short-term use of the r-hGH plus HPN in patients with excisable gastrointestinal cancer is safe, effective and benefit for the post-operative recovery.

ObjectiveTo study the early diagnosis and prevention of fungal infection in severe acute pancreatitis(SAP). Method 1.SAP patients from July 1998 to June 2002 were prospectively randomized into 3 groups: garlicin prevention group, fluconazole (low dosage) prevention group and control group, the incidence of fungal infection in SAP was compared between the groups. For fungal infection patients, the fungal clearance and mortality rate were observed. 2.Clinical data of SAP patients with fungal infection and with simple bacterial infection was compared by multivariate logistic regression, and clinical characters and risk factors of fungal infection were evaluated. Results 1.There were lower incidences of fungal infection in garlicin group (16% vs. 30%,P

Objective To determine the prevention and therapy of fungal infection in patients with severe acute pancreatitis (SAP). Methods Seventy patients with SAP admitted from July,1998 to June,2002 were randomly divided into 3 groups: garlicin prevention group, fluconazole (low dosage) prevention group and control group.The incidence of fungal infection, the fungal clearance and mortality after the treatment were compared. Results The incidence of fungal infection in garlicin group and fluconazole group was lower than that in control group. (16%∶30%,P

Objective : To investigate the effect of mitochondrial fission protein 1 (FIS1) on apoptosis and cisplatin resistance in tongue squamous cell carcinoma (TSCC) cells. Methods : The squamous cell carcinoma cell lines SCC9 and CAL27 were used to detect the mRNA and protein levels of FIS1 after cisplatin treatment, the knockdown and overexpression of FIS1 of SCC9 and CAL27 with or without cisplatin treatment were accomplished through small interfering RNA (siRNA) and plasmid, respectively. The mitochondrial division state in cells was detected by mitochondrial staining, and the apoptosis state of cells was detected by TUNEL, flow cytometry and Caspase 3/7. Results: FIS1 protein expression in tongue squamous carcinoma cells treated with cisplatin was increased, but the mRNA level did not change. Silencing of FIS1 expression reduced mitochondrial division and apoptosis in squamous cell carcinoma cells treated with cisplatin, whereas overexpression of FIS1 exhibited the opposite effects. The percentage of dividing mitochondria, the number of apoptotic cells and the activity of Caspase 3/7 in SCC9 and CAL27 cells were significantly different before and after modulation of FIS1 expression (P < 0.05). Conclusion FIS1 is involved in the regulation of cisplatin chemotherapy sensitivity in tongue squamous cell carcinoma and can be used as a new target for improving the sensitivity of cisplatin chemotherapy in oral squamous cell carcinoma.

Objective : To investigate the differential expression of mitochondrial microRNAs (mitomiRs) in tongue squamous cell carcinoma (TSCC) and to screen out mitomiRs related to chemotherapy resistance. Methods : Mitochondrial, cytoplasmic, and total cellular RNAs were extracted from the squamous cell carcinoma cell line CAL-27 and the cisplatin-resistant cell line CAL-27-re. High-throughput miRNA microarrays were used to screen for differentially expressed mitomiRs between the drug-resistant and parental cells. The upregulated mitomiRs in the CAL-27 and CAL-27-re cells and in samples from chemoresistant and chemosensitive tongue squamous cell carcinoma patients were verified by qRT-PCR. Results: The microarray detected 263 miRNAs in 6 components of the mitochondrial, cytoplasmic and total cellular RNAs from the CAL-27 and CAL-27-re cells, including 57 mitomiRs and 134 cytoplasmic microRNAs (cytomiRs). Compared with the total miRNAs, 35 mitomiRs were upregulated in the CAL-27-re cells, and 31 mitomiRs were upregulated in the CAL-27 cells (≥ 1.5-fold). Further comparative analysis of mitomiRs that were differentially expressed between the parental and drug-resistant cells identified 11 upregulated mitomiRs (miR-2392, miR-4462, miR-1290, miR-4449, miR-1268a, miR-1246, and miR-371a-5p, miR-3934-5p, miR-4271, miR-513p, and miR-664b-3p) and 5 downregulated mitomiRs (miR-188-5p, miR-1973, miR -3653, miR-4499, and miR-5787); the expression levels of the other 41 mitomiRs were almost identical in both cell lines. The qRT-PCR results were consistent with the miRNA microarray results. The 11 upregulated mitomiRs that were validated between the CAL-27 and CAL-27-re cells included miR-1268a, miR-2392, miR-4462, and miR-1290. Additionally, 5 mitomiRs, including miR-4449, were upregulated in the clinical chemotherapy-resistant tongue squamous cell carcinoma samples. Conclusion Differentially expressed mitomiRs were found between cisplatin-resistant and cisplatin-sensitive tongue squamous cell carcinoma cells. mitomiRs with high expression levels (miR-2392, miR-4462, miR-1290, miR-4449 and miR-1268a) may play important roles in the drug resistance of tongue squamous cell carcinoma.
