ObjectiveTo observe the effect of succus entericus reinfusion with continuous enteral nutrition on the barrier function of intestinal mucosa and nutritional status in patients with stomal type fistulas. Methods Sixteen patients with stomal type fistula from July 1995 to May 2008 were enrolled in the study. A]l patients met the following conditions: gut function returned normal; abdominal infection was controlled; total enteral nutrition was provided ; and the length of small intestine for succus entericus reinfusion was more than 50 cm. Intestinal mucosa was taken at 25 to 30 cm away from stoma of fistula by endoscope 0, 7, and 14 days after reinfusior. Hematoxylineosin staining was performed to count the number of intestinal intraepithelial lymphocytes (IIELS). In addition,proliferating cell nuclear antigen (PCNA) was measured with immunohistochemical staining. Serum protein levels were determined by immunonephelometry. ResultsThe percentage of IIELS in intestinal mucosa ( 19.06％ ±4.81％ vs. 12.81％ ±2.95％, P=0.000) and the percentage of PCNA positive cells ( 12.13％ ±4.33％ vs.6.44％ ± 2.34％, P =0.000) 14 days after succus entericus reinfusion were significantly higher than those on the day of reinfusion. Serum fibronectin level increased from ( 152.80 ± 16.50 ) to ( 227.05 ± 45.36 ) mg/L ( P =0.000), and transferring protein level increased from ( 2.16 ± 0.52 ) to ( 2.62 ± 0.41 ) g/L ( P =0.017 ) 14days after succus entericus reinfusion. ConclusionSuccus entericus reinfusion is effective in protecting the intestinal mucosa in patients with stomal type fistulas.

Clinical data of 14 patients with iatrogenic duodenal injuries treated in hospital from January 2000 and January 2010 were retrospectively reviewed.Iatrogenic duodenal injuries were found intraoperatively in 9 cases,in whom repair or additional jejunostomy was performed and all were cured and discharged.In 2 patients the duodenal injuries were found within 24 hours postoperatively,1 was cured,another had low flow duodenal fistula and cured with conservative treatment.Duodenal bypass and extraoral drainage were performed in 2 patients whose duodenal injuries was found 72 hours after surgery and died from severe infection of retroperitoneal space and multiple organ failure respectively.One patient whose duodenal injury was found 7 d postoperatively suffered from septic shock and died in 4 h after admission.The results suggest that early detection and early management would result in satisfied outcome for patients with iatrogenic duodenal injuries,the first 24 hours are crucial.

Objective To investigate the clinical efficacy of the curettage and aspiration technique in laparoscopic radical gastrectomy for the treatment of gastric cancer.Methods The clinical data of 55 patients who received laparoscopic radical gastrectomy by curettage and aspiration technique with Peng's multifunctional operative dissector at the Shaoxing People's Hospital from June 2008 to February 2011 were retrospectively analyzed.Tumors located at the upper stomach in 10 patients,at the middle stomach in 15 patients and at the lower stomach in 30 patients.The numbers of patients had tumor in TNM stage Ⅰ,Ⅱ,Ⅲ A were 16,35 and 4.Patients were followed up via phone call and out-patient examination till October 2013.Results Laparoscopic radical gastrectomy was successfully carried out on all the 55 patients.Of the 55 patients,39 received laparoscopic distal subtotal gastrectomy and 16 received laparoscopic total gastrectomy.The operation time,volume of intraoperative blood loss,number of lymph nodes dissected,distances of proximal and distal resection margins to the tumors,time to flatus,time to fluid diet and duration of postoperative hospital stay and incidence of postoperative complications were (241 ± 42)minutes,(273±115)mL,32 ±9,(5.8±1.4)cm,(5.1 ±l.7)cm,(78 ±24)hours,(95 ±17)hours,(12 ±4)days and 7.3％ (4/55),respectively.Two patients were complicated with pulmonary infection,1 with anastomotic fistula,1 with incisional infection,and all of them were cured by symptomatic treatment.No patients died perioperatively.All the 55 patients were followed up for 12.0-55.0 months,and the mean time of follow-up was 35.9 months.The cumulative 48-month survival rate was 54.8％.The postoperative recurrence and metastasis rate was 10.9％ (6/55).Peritoneal metastasis was detected in 2 patients,liver metastasis in 1 patient,para-aortic nodes metastasis in 1 patient,residual gastric metastasis in 1 patient,and bone metastasis in 1 patient.Conclusion Laparoscopic radical gastrectomy by curettage and aspiration technique is safe and feasible,with the advantages of minimal trauma,low morbidity and quick recovery.

OBJECTIVETo investigate the expression of secretory leucocyte protease inhibitor (SLPI) in colon cancer and their clinical significance.

METHODSImmunohistochemistry was performed to detect the SLPI expression in colon cancer tissue microarray. The expression of SLPI was scored by two pathologists and was analyzed using Χ(2) test to explore its influence on the pathologic characteristics of colon carcinoma.

RESULTSSLPI was up-regulated in colon cancer tissue compared to normal mucosa. Overexpression of SLPI protein was correlated with differentiation grade (low differentiation: 42.1% vs 57.9%; moderate/well differentiation: 2.3% vs 97.7%, TNM stages(III-IV:29.4% vs 70.6%;I-II:3.1% vs 96.9%), lymph node metastasis (28.6% vs 71.4%) and distant metastasis (84.6% vs 15.4%), but not with patient age or sex.

CONCLUSIONSLPI overexpression correlates with aggressive pathologic characteristics of colon cancer and it may server as prognostic factor of colon cancer patients. Further research will be carried out to verify whether SLPI can become a new target for colon cancer treatment.

Objective:By comparing the comprehensive differences between volume-modulated arc therapy (VMAT)-and CyberKnife-6D Skull (CK-6D Skull) tracking technology-based stereotactic radiotherapy (SRT) plans in the treatment of multiple brain metastatic tumors, and explore the advantages of multi-target intracranial technology.Methods:Clinical data of 42 patients with more than 2 brain metastases who received STR between January 2017 and August 2018 were retrospectively analyzed. For each patient, two radiotherapy plans were designed by selecting CK-6D Skull and VMAT technologies. The quality of VMAT and CK-6D Skull was compared by calculating the gradient index (GI), dose sag volume and organ at risk (OAR) of target area. The total number of monitor unit and single treatment time were recorded to compare the execution efficiency of these two technologies.Results:The GI of intracranial 2-target and 3-target plans of CK-6D Skull technology was significantly superior to that of VMAT technology ( P<0.05). The GI did not significantly differ between the 4-target and the 5-target groups ( P>0.05). The contribution of these two technologies to the maximum dose of OAR was not significantly different ( P>0.05), whereas the treatment time of VMAT technology was shorter ( P<0.05). Conclusions:Both technologies can meet the requirements of clinical SRT for multiple brain metastatic tumors. From the perspective of treatment plan and implementation, SRT based on CK-6D skull technology is recommended for patients with less than 4 intracranial metastatic tumors, and VMAT-based SRT is considered for those with > 4 metastatic tumors. Patients with poor physical condition and difficulty in maintaining a fixed position for a long time shall give priority to VMAT technology. More differences between these two technologies in the implementation of SRT for intracranial multiple brain metastases remain to be elucidated by more case data for statistical analysis.
