RESUMEN
<p><b>OBJECTIVE</b>To compare the outcomes of early oral feeding (EOF) and the traditional oral feeding (TOF) in postoperative patients with colorectal cancer using Meta-analysis.</p><p><b>METHODS</b>The databases of PubMed, SCI, Ovid, The Cochrane Library, CNKI, CBM, VIP and Wanfang Data were searched to collect randomized controlled trial (RCT) about EOF versus TOF in patients undergoing elective colorectal surgery. The retrieval time span was from inception to June 1, 2016. The studies were screened according to the inclusion and exclusion criteria. The data were extracted and the quality was evaluated by 2 reviewers independently. The Meta-analysis was conducted using RevMan 5.2 software.</p><p><b>RESULTS</b>A total of 14 studies with 1 807 patients (906 cases in EOF group and 901 cases in TOF group) were included. The time to first passage of flatus (MD=-16.11 h, 95%CI:-18.27 to -13.94 h, P=0.00), postoperative hospital stay (MD=-1.92 d, 95%CI:-2.83 to -1.01 d, P=0.00), hospitalization cost (ten thousand yuan) (MD=-0.58, 95%CI:-0.71 to -0.46, P=0.00) were less in EOF group compared to TOF group. EOF patients had lower total complication rate (OR=0.68, 95%CI:0.48 to 0.95, P=0.03), in which the pulmonary infection (OR=0.27, 95%CI:0.13 to 0.53, P=0.00), pharyngolaryngitis (OR=0.06, 95%CI:0.04 to 0.11, P=0.00) were lower than those in TOF group, while the tube reinsertion (OR=2.34, 95%CI:1.08 to 5.07, P=0.03) was higher. The incidence of anastomotic leakage, nausea, vomiting, abdominal distension, diarrhea, and wound infection between two groups was not significantly different(all P>0.05). There was no significant difference between two groups in IgM (P>0.05), while the IgA (MD=0.3, 95%CI:0.12 to 0.48, P=0.00), IgG (MD=2.13 ,95%CI:0.82 to 3.44, P=0.001), CD4+ (MD=3.80, 95%CI:2.55 to 5.04, P=0.00), CD4+/CD8+ (MD=0.22, 95%CI:0.04 to 0.41, P=0.02) in EOF group were higher than those in TOF group. Postoperative CRP decreased rapidly in EOF group (MD=-30.10, 95%CI:-48.07 to -12.13, P=0.00), and IL-6 was not significantly different (P>0.05). EOF patients had higher serum albumin level 5 days after operation (MD=3.27, 95%CI: 2.48 to 4.07, P=0.00).</p><p><b>CONCLUSIONS</b>EOF can promote gas passage and defecation, reduce postoperative hospital stay and treatment costs. Also, it can decrease the incidence of complications and postoperative inflammation, and maintain immune function.</p>
RESUMEN
Objective To evaluate the diagnosis value of spiral CT in leiomyosarcoma of abdomen.Methods Both plain and enhanced CT fingdings in 12 cases with pathologic-proved leiomyosarcoma of abdomen were respectively analyzed.Results In all of 12 cases,1 case occurred in colon,1 case in rectum,1 case in small intestine,5 cases in mesentery,4 cases in retroperitoneum,CT positioning accuracy rate was 91.7 ％ (11/12).The volume was comparatively large,the average diameter was 6 cm.The density were uneven,nodosity or lamellar necrosis were found.Delay enhacement were occurred in lower density part in most part of cases (9/12).Conclusion The localization of spiral CT is comparatively accurate to the leiomyosarcoma of abdomen,some characteristics are found in CT image,but the final diagnosis depends on immunohistochemistry.
RESUMEN
OBJECTIVE: To explore the association between low flow rate and reperfusion injury during the process of preserving liver by cold machine perfusing perfluorochemical oxygen carder solution. METHODS: Forty-four male adult Wister rats were randomly divided into normal, control, experimental Ⅰ and experimental Ⅱ groups. In the normal group, the removed liver was performed isolated reperfusion guided by Clavien method. In the other 3 groups, the removed liver was infused through the portal vein by the 4-5 ℃ conserved perfluorochemical oxygen carder solution. The infused rate was controlled at 0.4, 0.2, 0.1 mL/(min·g) with 18 hours perfusion, After that, isolated reperfusion was performed. The activity of aspartate aminotransferase, alanine transaminase and endotheiin mass concentration of the effluent was detected at minutes 10, 30, and 60 after reperfusion. The histopathological changes of liver under light and election microscopy were also observed. RESULTS: The activity of aspartate aminotransferase, alanine transaminase and endothelin mass concentration had no remarkable differences between the experimental Ⅰ group and control group (P > 0.05). The differences between the experimental Ⅱ group and control group were remarkable (P < 0.05). The light and electron microscopy showed that the histopathological changes of liver in the control and experimental Ⅰ groups was lightener than experimental Ⅱ group. CONCLUSION: During the process of preserving liver by cold machine perfusion, the rate of 0.1 ml/(min·g) perfluorochemical oxygen carder solution increase the injury of hepatocyte and sinusoidal endothelial cells, which eventually result in severity of reperfusion injury.

ObjectiveTo determine the clinical effect and the prospect of cervical side-to-side stapled esophagogastric anastomosis. MethodsEighteen cases of upper and middle thoracic esophageal carcinoma were treated with esophagectomy and cervical side-to-side stapled esophagogastric anastomosis. The clinical data were collected and retrospectively analyzed. The average age of patients was 60.7 years and the ratio of male to female was 17∶1. The tumor included 4 upper part and 14 middle thoracic parts. The length of tumors was from 1 cm to 7 cm, with an average of 3.2 cm.ResultsThe post-operative TNM staging(AJCC) included 4 Stage Ⅱa,9 Stage Ⅱb,and 5 Stage Ⅲ. The operative incisions included 8 nontransthoracic cervical and abdominal double incisions, 9 right cervico-thoraco-abdominal triple incisions, and 1 left cervico-thoracic incision. One (5.56%) patient complicated with anastomotic leakage and was cured in 2 weeks by cervical drainage and absolute diet. All the 18 patients were followed up for 1 to 5 years,and no anastomotic stricture was found. Reflux esophagitis was found in 2 and the incidence rate was 11.11%.ConclusionCervical side-to-side esophagogastric anastomosis is a safe procedure with larger resection of margins and fewer complications. It is worth replicating.

Objective To investigate the feasibility of using a new type carina type tracheal prosthesis made of complex material to replace trachea and carina defects. Methods According to biomechanics index, a new carina type tracheal prosthesis was designed and constituted with carbon fiber and silicon. 19 dogs were divided into two groups randomly: group A(n=11), the carina type tracheal prosthesis anastomosed directly to dog′s trachea and bronchus;group B(n=8), based on group A, meanwhile the diaphragm was incised and the pedicel caul was transplanted from abdominal cavity to thorax to enwrap the carina type tracheal prosthesis and anastomotic site. Results The average survival period post operation in group A and group B were (3.462?1.849)d and (6.475?1.062)d ,respectively. There was significant difference of the survival period between two groups(P
RESUMEN
AIM: To evaluate the effect of endothelial Rho and Rho kinase in extravasation migration of sarcoma cell. METHODS: We used an in vitro model of sarcoma cell transmigration across a monolayer of HUVEC cultured on collagen gel to observe extravasation migration of sarcoma cells and calculated the electrical resistance of HUVEC monolayer in extravasation migration of sarcoma cells. RESULTS: Sarcoma cells migrated through endothelial cells into collagen gel, the electrical resistance of a HUVEC monolayer reduced in extravasation migration of sarcoma cells.Endothelial Rho inhibitor(C3 transferase) and Rho kinase inhibitor(Y-27632) inhibited extravasation migration of sarcoma cells and inhibited reduction of electrical resistance of a HUVEC monolayer in extravasation migration of sarcoma cells. CONCLUSION: Endothelial Rho and Rho kinase regulates sarcoma cell transendothelial migration through modification of endothelial cytoskeleton.
RESUMEN
AIM: To evaluate the effect of tissue factor on intravascular migration of tumor cells.METHODS: Expression of tissue factor in tumor cells (HT1080) was analyzed by flow cytometry and immunofluorescence staining. An in vitro model was used to observe intravascular migration of tumor cells. RESULTS: High expression of tissue factor was observed in tumor cells (HT1080). The antibody for tissue factor inhibited intravascular migration of tumor cells. CONCLUSION: Tissue factor stimulated tumor metastasis through promoting intravascular migration of tumor cells.
