OBJECTIVETo evaluate the therapeutic efficacy and adverse reaction of Aidi Injection (ADI) combined with FOLFOX4 regimen for treatment of patients with advanced colorectal cancer, and controlled with those of FOLFOX4 regimen alone.

METHODSOne hundred and seventeen patients were randomized into two groups. All received FOLFOX4 regimen, i.e. Oxaliplatin 85 mg/m2 intravenous dripping in 2 h on day 1, leucovorin CF 200 mg/m2 intravenous dripping and 5-FU 400 mg/m2 intravenous injection followed with 600 mg/m2 continuous infusion by micro-pump in 22 h on day 1 and 2, 14 days as one cycle. Besides, to the treatment group (65 patients), ADI was administered additionally by adding 60 mL ADI in 250 mL 5% glucose for intravenous dripping every day for 10 successive days, while to the control group (52 patients), no additional medication was given.

RESULTSThe response rate in the treatment group was 44.62%, and in the control group 30.77% (P = 0.126), the KPS score improving rate in the two groups was 66.15% and 40.38% respectively (P = 0.005), the 1-year survival rate was 53.85% and 40.38% respectively (P = 0.148), and the adverse reaction presented in the treatment group was greatly less than that in the control group (P < 0.05).

CONCLUSIONADI in combining with FOLFOX4 regimen can enhance the efficacy, reduce the adverse reaction of chemotherapy in treating advanced colorectal cancer, and could also improve the quality of life and prolong the survival time of patients.

ObjectiveTo investigate the application of intraoperative Computed Tomograph (CT) using in surgery for complex acetabular fractures.MethodsFrom June 2008 to December 2010,14 patients (9 males,5 females; with the mean age of 45.1 years; range,28-62 years) with complex acetabular fractures were operated using intraoperative CT.Preoperative radiotherapy and CT scan were adopted to evaluate the fractures.Three dimensional reconstruction based on CT scan was used to mimic surgery.The surgery approach and the type of internal fixators were noted.Intraoperative C-arm and CT scan were used to evaluate the fractures reduction respectively.Decision of additional reduction was made by surgeons according to above mentioned methods respectively and the results were noted.Comparing to preoperative design,the change of surgery plan were noted.Overall time,frequency and radiation dose of intraoperative CT scan were also noted.ResultsAll patients in this study received average 2.7 times of intraoperative CT scan.Mean time of CT scan was 40.4 min and the overall dose of radiation was 47.2 mGy.Decision of additional reduction was made in 3 cases according to C-arm radiography and 4 cases according to CT scan (above mentioned 3 cases were included).The change of surgery plan was made in one case.In postoperative radiography evaluation according to Matta's score system,anatomical reduction were achieved in 8 cases,imperfect reduction in 3 cases and poor reduction in 3 cases.ConclusionIntraoperative CT scan increases the radiation time and dose of patients dramatically.When used to evaluate fracture reduction intraoperatively,it can't take the advantage of traditional C-arm radiography.When delicate preoperative plan is made with radiography and three dimensional reconstruction based on CT data,the efficiency of intraoperative CT scan for complex acetabular fractures are to be discussed.

Objective To investigate the effect of intercostal nerve block combined with general anesthesia on hemodynamics in patients undergoing video-assisted thoracoscopic surgery. Method From January 2014 to January 2016, 100 patients were selected and divided into control group and experimental group according to the principle of complete random grouping. The patients in control group received general anesthesia with intravenous induction and static-occlusion, and the patients in experimental group received intercostal nerve block compound general anesthesia. The changes of visual analogue pain scores (VAS) and hemodynamics were evaluated in both groups. Changes in immune function before and after treatment were compared. Hemodynamic parameters include heart rate (HR), systolic blood pressure (SBP) and pulse oxygen saturation (SpO2). Immune function parameters include serum T cell subsets content. Results The VAS scores of the experimental group were significantly lower than those of the control group at different time points (P < 0.05). The systolic blood pressure and heart rate were significantly higher in the control group than those in the experimental group after the operation (P < 0.05). The CD4+, CD4+/CD8+levels in the test group were significantly higher than those in the control group (P < 0.05). Conclusion Intercostal nerve block composite anesthesia can better control the thoracoscopic patient's cardiovascular response and reduce the immune function inhibition. It is worthy of clinical promotion.
