RESUMO
Objective To evaluate the clinical value of 3.0T magnetic resonance imaging (MRI) diffusion weighted imaging (DWI) on evaluation effect of neoadjuvant chemotherapy in advanced gastric cancer. Methods 3.0 T MRI DWI examination was performed in 42 cases of advanced gastric cancer diagnosed by gastroscopy and pathology, including 32 patients were examined with DWI both before and after chemotherapy. Lymph nodes of gastric cancer lesions and display ability of stomach were measured, and the area of the apparent diffusion coefficient (ADC) values in normal stomach and tumors were compared. ADC values were compared in the same patients before and after neoadjuvant chemotherapy and analyzed along with postoperative pathological examinations. Results In a total of 40 patients who received 74 DWI examinations, ADC values in tumor and lymph nodes were significantly higher than those in normal tissue. The ADC value in tumors was (1.348 ±0.278) ×10-3 mm2/s, and in 12 cases of stomach lymph node enlargement was (1.329±0.188) ×10-3 mm2/s. However, the average ADC value of normal stomach was (2.081± 0.189) ×10-3 mm2/s with significantly lower DWI than that of the former (P< 0.001). After chemotherapy, the ADC value in tumors was increased, which was (1.572 ±0.261) ×10-3 mm2/s (P< 0.001). After neoadjuvant chemotherapy, 16 patients received gastric cancer radical prostatectomy, and postoperative pathological TRG ratings of tumor were decreased with different extent. Tumor cell density (TCD) before treatment with an average of 4.45 ×10-5 / px2, which was downgraduated to 2.48 ×10-5 / px2 after chemotherapy and surgery. Negatively correlation between TCD values and ADC values were observed. Conclusion MRI DWI examination can effectively detect advanced stomach cancer and the associated lymph node enlargement. Comparison of tumor morphology and ADC values in advanced gastric cancer before and after neoadjuvant chemotherapy has clinical value in prognosis.
RESUMO
<p><b>OBJECTIVE</b>To study the clinicopathologic characteristics, immunophenotypes, pathologic diagnosis and differential diagnosis of gastrointestinal inflammatory fibroid polyp (IFP).</p><p><b>METHODS</b>The clinical data, histologic features and immunohistochemical results of 6 cases of gastrointestinal inflammatory fibroid polyp were analyzed, with review of literature.</p><p><b>RESULTS</b>There were altogether 5 women and a man. The age of patients ranged from 44 to 87 years (median age = 61 years and mean age = 62 years). The sites of involvement included stomach (number = 2), jejunum (number = 2), distal ileum (number = 1) and rectum (number = 1). The patients often presented with abdominal pain or discomfort and tarry stool. All the cases studied showed similar morphology, were submucosa-based and composed of bland spindle cells associated with loose collagenous stroma and perivascular edema. Prominent concentric fibroblastic proliferation ("onion-skin" appearance) and eosinophilic infiltrate were characteristics. Three of the patients underwent surgical resection. The remaining patients had the lesions removed with endoscopy. Follow-up data were available in 5 patients and none of them had disease recurrence or metastasis.</p><p><b>CONCLUSIONS</b>IFP is a rare benign tumor of gastrointestinal tract. Correct diagnosis primarily relies on pathologic examination. It needs to be distinguished from gastrointestinal stromal tumors or inflammatory myofibroblastic tumor.</p>

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.
RESUMO
Objective To explore the effects of pelvic floor electrical stimulation (PES) on constipation in patients with spinal cord inju-ry (SCI). Methods 40 patients with SCI were randomly divided into conventional group and PES group with 20 patients in each group. The conventional group was treated with health education, psychological care, diet care and massage. The PES group was treated with PES in ad-dition. They were assessed with symptoms of constipation and efficacy assessment score. Results The symptoms of constipation and effica-cy assessment score decreased significantly in the PES group (P0.05). And the score was low-er in the PES group than in the conventional group (P<0.01). Conclusion PES can help eliminate constipation in patients with SCI.
RESUMO
Cell adhesion mediated by cell adhesion molecules (CAMs) constitutes essential life phenomenon. In inflammation, immunity, infection, thrombosis, tumor metastasis and wound healing, cell adhesion comes into being the basic physiological and pathological process. Intervening with cell adhesion has been the important therapeutic and prophylactic strategies for diseases. Accumulated evidence has indicated that plant polysaccharides especially those exacted from Chinese traditional and herbal drugs displayed various pharmacological effects such as anti-inflammation, anti-cancer, anti-infection, immunomodulation, cardiovascular protective effects and so on. In this paper, the research progress of plant polysaccharides on cell adhesion is reviewed.
RESUMO
AIM: To study the possibility that yellow wine improves the pathological changes of atherosclerosis in vivo. METHODS: Six weeks old LDL receptor knockout mice (n=48) on a high-fat and L-methionine diet developed plasma hyperhomocysteinemia and atherosclerosis. The animals were randomly divided into yellow wine group, red wine group, ethanol group and control group (n=12 in each group) and were sacrificed after 14 weeks. The levels of plasma lipids and homocysteine in serum were examined. The morphological changes of aorta artery and the atherosclerosis of aorta sinus were observed under microscope. The expression and activation of matrix metalloproteinase-2 (MMP-2) were determined by the method of immunohistochemistry. RESULTS: No significant difference of plasma total cholesterol, triglyceride or high density lipoprotein cholesterol among groups was observed. Plasma homocysteine was significantly decreased in yellow wine group as compared to other three groups (P<0.01). Compared to ethanol and control groups, use of yellow wine and red wine significantly reduced the atherosclerosis lesion area (P<0.01). However, no significant discrepancy between the yellow wine group and red wine group was found. Compared to control group, the expression of MMP-2 in yellow wine group, red wine group and ethanol group decreased by 26.3%, 27.6% (P<0.01) and 5.7% (P>0.05), respectively. The activity of MMP-2 in yellow wine group, red wine group and ethanol group decreased by 31.7%, 32.5% (P<0.01) and 6.7% (P>0.05), respectively. CONCLUSION: Yellow wine and red wine inhibit the expression of MMP-2 and improve the pathologic changes of atherosclerosis, indicating that they have benefic effects on cardiovascular system.
