Proteome is a discipline which researchs the composition and the dynamic alteration of proteins.As the result of the progression in the clolorcetal cancer,the proteins expression showing a dynamic change process.The technique of proteome can perform qualitative and quantitative analysis for the proteins,and perform contrastive analysis for the normal hunman proteins metabolic.So we can screen the biomarkers that are associated with coloretal cancer progression.The article aims to summarize the proteome in the researching of the colorectal cancer.And summing up the biomarkers that are associated with the diagnosis,prognosis and treatment of the coloretal cancer.

Objective To observe the curative effect of abdominal acupuncture on postoperative pain of patients with mixed hemorrhoid after Milligan-Morgan hemorrhoidectomy.Methods A total of 100 mixed hemorrhoid patients with postoperative pain after Milligan-Morgan hemorrhoidectomy under spinal anaesthesia from September of 2014 to December of 2015 were included into the study.The patients were evenly randomized into trial group and control group.The trial group was treated with abdominal acupuncture at acupoints of Shuifen,Guanyuan,Qihai,Sanxing needles under Qihai,lower Fengshi,Tianshu for 15-30 min.The control group was treated with intramuscular injection of Tramadol Injection 0.1 g.Before treatment and 0.5,1,2,3 hours after treatment,the pain visual analogue scale (VAS) scores and body activity scores were recorded.Results (1) After treatment,pain VAS scores of the two groups at different time points were obviously decreased(P ＜ 0.05 compared with those before treatment),and the decrease of pain VAS scores of the treatment group 0.5 hours after treatment was superior to that of the control group (P ＜ 0.05),but there was no significant difference between the two groups at other time points (P ＞ 0.05).(2) After treatment,body activity scores of the two groups at different time points were obviously decreased(P ＜ 0.05 compared with those before treatment),but the difference was insignificant between the two groups(P＞ 0.05).(3) The average dose of Tramadol Injection used in the trial group was 0.013 ± 0.034 1 g,while was 0.103 ± 0.017 7 g in the control group,the difference being significant (P ＜ 0.05).Conclusion The analgesic effect of abdominal acupuncture is similar to that of Tramadol Injection.For its safety,and being cheap,practical and painless,abdominal acupuncture can be expected to be another option of effective analgesic method for the postoperative pain of patients with mixed hemorrhoid after Milligan-Morgan hemorrhoidectomy.

Objective To establish a new method based on Taqman's fluorescent ARMS-PCR technique for detecting the KRAS mutations in human paraffin embedding tissue samples,which is a reference value of clinical medication.Methods Specific primers and probes were designed based on the conserved sequences of KRAS and internal reference genes(GAPDH).Taqman's fluorescent ARMS-PCR detection systems and sequencing systems were established for KRAS detection.In this paper,paraffin embedded tissue samples of 200 patients with colorectal cancer(CRC)are detected and compared with gold standard Sanger sequencing.The results of KRAS gene mutation are statistically analyzed,and the consistency of the two detection methods is analyzed.Results This method is able to detect KRAS gene mutations in human paraffin embedding tissue samples.And the results are 100％consistent with Sanger sequencing.Conclusion The method based on Taqman's fluorescent ARMS-PCR established in this research can detect KRAS mutations simply,quickly and accurately,which is valuable for clinical medication and suitable for clinical application.
