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.

OBJECTIVETo construct a recombinant lentiviral vector that stably express hepatocyte nuclear factor 6 (HNF6) in colorectal cancer cell line and examine its effects on the invasive ability of SW620 cells.

METHODSThe lentiviral vector pLeno-DCE-HA-HNF6 was constructed and transfected into 293T cells. The supernatant containing the lentivirus particles was harvested to determine the virus titer. A stable cell line was established by infecting SW620 cells with the lentivirus particles, and the transfection efficiency was examined by fluorescence microscopy and flow cytometry. The invasion ability of the transfected SW620-HNF6 cells was assessed by wound healing and transwell assays.

RESULTSThe recombinant lentiviral vector was correctly constructed and verified by sequencing. SW620-HNF6 cell line with stable HNF6 expression was established successfully, and the transfection efficiency reached 82.3%. Western blotting and quantitative PCR demonstrated significantly upregulated HNF6 expression in SW620-HNF6 cells, which showed obviously suppressed invasive ability in wound healing and transwell assays.

CONCLUSIONWe have successfully established a colorectal cancer cell line SW620-HNF6 stably expressing HNF6, which shows a lowered migration activity in vitro.

Objective To investigate the value of enhanced recovery after surgery (ERAS)in the perioperative period of intertrochanteric femoral fractures in elderly patients. Methods A retrospective analysis of 100 elderly patients with intertrochanteric femoral fractures at Shenyang Shengjing Hospital from January 2014 to January 2017 was conducted. According to the treatment , patients were divided into two groups :an ERAS group and a routine group (n = 50 ,each ). Hospitalization times ,postoperative pain visual analogue scales (VAS ) ,complication rates ,operation times ,evaluated byHarris hip scores and other parameters were compared between the two groups. Results All patients were followed up for 20 months(mean=18.7 months). The hospitalization time and postoperative pain VAS score were shorter or lower in the ERAS group than in the routine group [(6.06±1.89)d vs. (8.02 ± 1.89)d ,3.02 ± 1.79 vs.3.66 ± 1.06 ,both P＜ 0.05].There was a significant difference in rates of complications (delirium and urinary tract infection )between the groups (P＜ 0.05).There was no statistically significant difference in operation time or Harris hip score between the groups one year after surgery (both P ＞ 0.05 ). Conclusions ERAS in treating intertrochanteric femoral fractures in the elderly can significantly reduce the length of hospital stay , postoperative pain and complications ,and should be recommended.

Objective:To investigate the effects of hematopoietic progenitor kinase 1 (HPK1) overexpression by construction of lentiviral vector on the proliferation and apoptosis of breast cancer MCF-7 and MDA-MB-231 cells,and to elucidate its possible mechanism.Methods:The cells were infected with the lentivirus overxpressing HPK1,and the MCF-7-HPK1 and MDA-MB-231-HPK1 cell lines were stably expressed HPK1;each cell line was divided into three experimental groups:blank group (untreated),control group (empty vector) and HPK1-overexpression group.The expression levels of HPK1 mRNA and protein in breast cancer cells in each group were detected by RTPCR and Western blotting methods,respectively.The cell proliferation rate was detected by MTT assay.The cell cycle and apoptotic rate were detected by flow cytometry.Transwell assay was used to analyze the cell migration ability.Western blotting method was used to measure the expression levels of caspase 3,PTEN,MMP-9,MMP-2,Ki-67and HPK1 proteins.Results:Compared with blank groups and control groups,the expression levels of HPK1 mRNA and protein in the both cell lines in HPK1 overexpression groups were significantly up-regulated (P＜0.05),the proliferation rates were significantly decreased (P＜0.05) and the apoptotic rates were significantly increased (P＜0.05),the number of cells crossing matrigel was significantly reduced (P＜0.05),the cell cycle of MCF-7 was blocked in G1 phase (P＜0.05),the expression levels of caspase 3 and PTEN proteins in HPK1 overexpression group were significantly increased (P＜0.05),and the expression levels of MMP-2 and MMP-9 proteins were significantly decreased (P＜0.05).Conclusion:HPK1 overexpression can inhibit the proliferation and migration of MCF-7 and MDA-MB-231 cells and induce apoptosis,which may be related to the up-regulation of caspase 3 and PTEN and down-regulation of MMP-9,MMP-2 and Ki-67.
