The only possible cure for patients with locally advanced colorectal cancer is multivisceral resection. With the development of oncological surgery techniques and various types of targeted cancer therapy drugs, treatment modality of multidisciplinary team has been proposed and implemented. How to choose the optimal treatment strategy is a common problem.

It has been fully studied about interstitial cells of Cajal in gastrointestinal tract,and in recent years these cells are discovered in other tissues and organs,such as urinary system,cardiovascular system,reproductive system,liver,pancreas and mammary gland.The criterion and process reported by some authors are reliable for invesgating these cells,and can be helped to study the distribution and function of these cells outside gastrointestinal tract.It is showed that the fuction of interstitial cells of Cajal exsited in urinary organs seems to be related with the spontaneous rhythmic contraction of smooth muscle,while in heart seems to cause atrial fibrillation in humans,but the poteinal fuctions of interstitial cells of Cajal in other tissues and organs have not been revealed.

Most studies show that the blood transfusion can promote patients tumor recurrence, and lower their 5-year survival rate. Even patients in the early phase, a small amount of blood transfusion has significant effect. Blood transfusion causing tumor recurrence may be due to that blood transfusion recipients suppressed immune function, resulting in rapid growth of residual tumor cells. In this paper, blood transfusion for patients with tumors will be discassed. induding the benefit and danger of blood transfusion autotransfusion and blood substitutes for patients with tumors ,and development of transfusion medicine in our country.

Objective To summarize the current status and development of therapy for anal canal cancer. Methods Application of Medline database and CHKD database, with "anal canal cancer", "chemotherapy", "radiotherapy", "abdominoperineal resection" as key words search literature about anal canal cancer published from January 1996 to June 2009. Retrieval criteria: the epidemiology of anal canal cancer; the etiology of anal canal cancer; the clinical manifestation and classification of anal canal cancer; strategies and development of therapy for anal canal cancer. Sixty-seven of them met the retrieval criteria, while finally 22 related papers were analyzed. Results Over the last 30 years, treatment of anal canal cancer has undergone a profound evolution. Combined-modality treatment combined with chemoradiotherapy (CRT), including three-dimensional conformal radiation therapy (3D-CRT), intensity modulated radiation therapy (IMRT), novel anti-tumor agent and salvage surgery, had resulted in a 5-year survival rate of approximately 80 %. Conclusion Anal canal cancer is a rare tumor. CRT has replaced surgery as the first choice of anal canal cancer. The development of molecular biology will likely lead to further proposals for trials of anal canal cancer.

Metabolic abnormality is correlated with the incidence of colorectal cancer.Metabolic syndrome is consisting of abdominal obesity,dyslipidemia,high blood pressure,sugar metabolic abnormality,and all of these factors are associated with colorectal cancer.Abdominal obesity and sugar metabolic abnormality may be the primary factors causing rectal cancer.Visceral fat is physiologically more active than subcutaneous fat.Visceral fat can produce and secret hormones and cytokines,which are involved in inflammation and metabolism,therefore the amount of visceral fat may directly or indirectly related to the occurrence of colorectal cancer.Obesity acts as a risk factor for colorectal cancer by several mechanisms,including high blood insulin,insulin-like growth factor,and the change of the adipose cytokines concentrations.Metabolic biomarkers may not only provide clues of colorectal carcinogenesis from the point of view of etiology,but also can help to explore new obesity phenotypes that is relevant to incidence risk of colorectal cancer.

Denervation is the abscission or destruction of the nerve,and when the endogenous and exogenous nerves distribited in the colon would be damaged,the colon would become a denervated one.That may be a result of surgical process or the symptom of disease such as Hirschsprung's disease.The denervated colon would have some changes in motility,absorption and secretion,thus the function of the colon would be affected.

Objective To detect the expression of angiotensin Ⅱ type 1 receptor (AT1R) in the different fibrotic stages of human liver. Methods The collagen Ⅰ was detected by immunohistochemical method. Indirect immunofluoresence-labelled method was used to detected AT1R. And semi-quantitative RT-PCR was used to detect AT1R mRNA. Results The type Ⅰ collagen area enlarged with the progression of hepatic fibrosis. The positive expression of AT1R was concentrated in the cytoplasm of hepatic stellate cells(HSC) around the lobes of liver or in the hepatic sinus. Eight of twelve cases of normal liver tissues were positive, and all the eighteen cases of fibrotic liver tissues were positive. The positive cell number in fibrotic liver tissues was significantly higher than that in normal ones (P

BACKGROUND:A large number of clinical trials have found that the number of bone marrow stem cels at the femoral neck and proximal femur in patients with osteonecrosis of the femoral head is significantly reduced, accompanied by decreased activity, which causes a significant decrease in osteogenic capacity that the necrotic bone cannot be effectively repaired after absorption, leading to the colapse of the femoral head. OBJECTIVE:To probe into the early clinical efficacy of autologous peripheral blood mononuclear cel transplantation with porous core decompression for treatment of avascular necrosis of the femoral head. METHODS:Forty-five patients with avascular necrosis of the femoral head (49 hips) were enroled in this study, and underwent autologous peripheral blood mononuclear cel transplantation with porous core decompression. After treatment, pain scores, Harris hip score, scores on the satisfaction of patients were evaluated, as wel as X-ray, CT and MRI examinations. RESULTS AND CONCLUSION:Al the patients received a folow-up visit of 11-14 months, averagely (12.5±0.6) months. During the folow-up, there were no complications and serious adverse reactions. Postoperative pain scores and Harris scores were both improved significantly compared with preoperative ones (P < 0.05). At 12 months after treatment, the excelent satisfaction rate was up to 92%. Patient’s MRI low signal region accounting for a percentage of the volume of the femoral head was decreased from (40.1±7.34)% preoperatively to (20.23±5.4)% at 6 months postoperatively, and there was a significant difference (P < 0.05). These findings indicate that autologous peripheral blood mononuclear cel transplantation with porous core decompression for treatment of avascular necrosis of the femoral head has significantly clinical effects at early stage, which can obviously reduce joint pain, improve and restore hip joint function, and delay progression of disease.

Objective To investigate the clinical features and prognostic factors of nasal type NIGT cell lymphoma(NKTCL).Methods Records of 61 patients with pathologically confirmed nasal type NKTCL were reviewed.Detailed clinical and laboratory data were included in univariate analysis, and statistically significant factors in univariate analysis were then included in multivariate analysis.Results In univariate analysis,Ann Arbor stage,performance status,IPI,number of extra-lymphatic site,B symptoms,LDH and β-MG level.were found to be the prognostic factors associated with time to overall survival in nasal type NKTCL.In multivariate analysis, Ann Arbor stage,performance status,LDH and β2-MG level were independent prognostic factors of overall survival.Conclusion Ann Arbor stage,performance status,LDH and β2-MG level were demonstrated as independent prognostic factors of the overall survival in nasal type NKTCL.

[Objective] To discuss the mechanism and relative problems of lumbar traction. [Method] Relevant articles and retrospect clinical data in the author's hospital were reviewed. Review relevant articles and retrospect clinical data of our hospital. [ Result ] Traction force : 40 kg + 15% ～ 20% of body weight, fineness rate reached 83.5% in 1606 patients being treated. According to course of disease, fineness rate was 90. 1% in the group of less than 3 years, 68.2% in the group of more than 3 years. [ Conclusion] Lumbosacral nerve root leave the peak of the protruding nucleus and establish a new harmonious "root-disc" relationship after traction. The pressure and tension to the nerve root reduces or disappears, meanwhile, the pain of low back and leg is alleviated or eradicated. Appropriate traction weight and correct traction body posture are key factors of good therapeutic effect.
