Objective To explore the clinical effects of postoperative restrict rehydration on different body mass index (BMI) of patients with colorectal cancer. Methods From January 2008 to January 2009, the patients diagnosed definitely as colorectal cancer were analyzed retrospectively. The postoperative early rehabilitations were studied and compared in different fluid therapy with different BMI (underweight group, normal group, overweight group).Results The first defecation time, aerofluxus time and ambulation time of the fluid restriction group were significantly earlier than those of the tradition therapy group (Plt;0.05), and postoperative in-hospital time was also less (Plt;0.05). However, the differences of early postoperative rehabilitation among underweight group, normal group and overweight group in the tradition therapy group and fluid restriction group had no statistical significance (Pgt;0.05). The complications such as pulmonary infection, anastomotic leakage, intestinal obstruction and wound dehiscence in the fluid restriction group were significantly lower than those in the tradition therapy group (Plt;0.05). In the tradition therapy group, the incidences of anastomotic leakage and wound dehiscence in overweight group were significantly higher than those in the underweight and normal group (Plt;0.05). The rate of postoperative complications among underweight group, normal group and overweight group in the fluid restriction group had no statistical significance (Pgt;0.05). Conclusion Postoperative restrict rehydration for overweight colorectal cancer patients has a good clinical effect, which can promote the early postoperative rehabilitation.
ObjectiveTo observe the effect of tert-Butylhydroquinone (tBHQ) on the expression of nuclear factor erythroid 2-related factor 2 (Nrf2), heme oxygenase (HO)-1 and phosphatidylinositol 3-kinase (PI3K) in high glucose cultured retinal Müller cells; and to investigate the anti-oxidative stress and anti-apoptotic effects of tBHQ.MethodsRetinal Müller cells were divided into normal glucose group (5.5 mmol/L, N group), high glucose group (45 mmol/L, HG group) and tBHQ intervention group (HG+tBHQ group). After retinal Müller cells were cultured with high glucose for 48 hours, the pretreatment with tBHQ (20 μmol/L) induced the expressions of nuclear factor erythroid 2-related factor 2 (Nrf2) and HO-1. The Müller cells were identified by immunofluorescence staining. The expressions of Nrf2, HO-1, PI3K, B-cell lymphoma-2 (Bcl-2) and Bax were detected by Western blot and real-time fluorescence quantitative PCR. Flow cytometry was used to detect the apoptosis of retinal Müller cells in rats.ResultsMüller cytoplasm and nucleus GS showed strong positive, large cell body, abundant cytoplasm, uniform green fluorescence; nuclear DAPI staining round or oval, clear boundary. The expression of Nrf2 protein (t=4.114, P=0.006), HO-1 protein (t=9.275, P=0.000), Nrf2 mRNA (t=7.292, P=0.000) and HO-1 mRNA (t=15.014, P=0.000) in the HG group were higher than those in the N group. The expressions of Nrf2 protein (t=7.847, P=0.000) ,HO-1 protein (t=7.947, P=0.000), PI3K protein (t=5.397, P=0.002), Bcl-2 protein (t=6.825, P=0.000), Nrf2 mRNA (t=18.046, P=0.000), HO-1 mRNA (t=39.458, P=0.000), PI3K mRNA (t=4.979, P=0.003) and Bcl-2 mRNA (t=9.535, P=0.000) in the HG+tBHQ group were significantly higher than those in the HG group. The protein and mRNA expressions of Bax protein in the HG+tBHQ group were significantly lower than those in the HG group (t=14.998, 16.520; P=0.000, 0.000). Flow cytometry showed that the apoptosis rate of Müller cells in the HG group was significantly higher than that in the N group (t=39.905, P=0.000). The apoptosis rate of Müller cells in the HG+tBHQ group was significantly lower than that in the HG group (t=21.083, P=0.000).ConclusiontBHQ can inhibit the apoptosis of retinal Müller cells by up-regulating the expression of Nrf2, HO-1 and PI3K.
Objective To explore the impact of restrictive fluid administration for patients with colorectal cancer combined diabetes. Methods The clinical data of patients diagnosed definitely as colorectal cancer with diabetes were analyzed retrospectively from January 2007 to October 2009 in this hospital, the clinical effects on postoperative early rehabilitation were studied and the differences between restrictive fluid regimen (fluid restriction group) and tradition fluid regimen (tradition therapy group) were compared. Results The time of first aerofluxus and the first ambulation in fluid restriction group were shorter than those of tradition therapy group, the differences had statistical significances (Plt;0.05). The incidence of wound infection in fluid restriction group was lower than that in tradition therapy group (Plt;0.05). The differences of preoperative hemoglobin (Hb), white blood cell (WBC), glucose (GLU) and blood urea nitrogen (BUN) were not statistically significant between two groups, but the difference of postoperative GLU was statistically significant between two groups (Plt;0.05). Conclusion Restrictive fluid regimen can reduce the incidence of common complications after colorectal surgery for diabetic, and has a certain promoter action to the early rehabilitation after rectal surgery.
Objective To discuss the clinical outcome of fast-track surgery for low/super-low rectal cancer. Methods Between October 2007 and December 2008, 120 patients underwent low/super-low rectal cancer resection without formation of stoma in the West China Hospital were analyzed retrospectively. Postoperative early rehabilitations were compared between fast-track group and traditional group. Results In early rehabilitations, time of first passing flatus, ambulation, oral intake, and pulling out urinary catheter and the hospital stay in fast-track group were significantly earlier than those in traditional group （Plt;0.05）, while there was no significant difference in time of using nasogastric tubes or drains （Pgt;0.05）. There was also no significant difference in postoperative morbidity of complications between the 2 groups （Pgt;0.05）. Conclusion Fast-track surgery for low/super-low rectal cancer is safe and can accelerate recovery with decreased length of hospital stay.
Objective To evaluate the effect of perioperative period clinical care mode through fast-track (FT) under nonminimal invasive operation on the inflammatory response of colorectal cancer resection. Methods Fifty-five patients underwent elective colorectal cancer resection were randomized divided into two groups: FT group (n=29) in which patients were performed FT perioperative care and tradition group (n=26) in which patients were received traditional perioperative care. The nonminimal invasive operations were performed in this study. The venous blood samples were respectively collected at 24 h before operation, at 24 h, 72 h, and 7 d after operation, and were used to detect the concentrations of serum C-reactive protein (CRP) and serum amyloid A protein (SAA).Results There was no complication such as infection, fistula of stoma and inflammatory ileus that was potential to influence the study results in two groups, and no patient died. The trend of changes in the concentrations of CRP and SAA of patients was accordant in each group. The peak concentrations of CRP and SAA of patients in FT group were respectively observed at 24 h after operation 〔CRP: (72.36±60.94) mg/L; SAA: (328.97±267.20) mg/L〕, while which were respectively delayed to 72 h after operation in tradition group 〔CRP: (112.71±63.92) mg/L; SAA: (524.18±331.03) mg/L〕. At the same time, the concentrations of CRP and SAA in FT group began to descend 〔CRP: (57.21±30.42) mg/L; SAA: (237.43±215.66) mg/L〕. The peak concentrations of CRP and SAA in tradition group were significantly higher than that in FT group (Plt;0.001) and the concentrations of CRP and SAA in FT group were significantly lower than those in tradition group at 72 h after operation (Plt;0.001). On 7 d after operation, the concentrations of CRP and SAA further decreased, but the difference between two groups was not significant (Pgt;0.05). Likewise, the concentrations of CRP and SAA at 7 d after operation were significant higher than those 24 h and 72 h after operation (Plt;0.001), lower than that 24 h before operation (Plt;0.001), respectively. Conclusion This study demonstrates that perioperative period clinical care mode through FT under non-minimal invasive operation can reduce the inflammatory response of colorectal carcinoma resections and scientific clinical care is an important means to promote quick rehabilitation.
