Epidemiology and treatment analysis of children with out-of-hospital cardiac arrest / 中华儿科杂志

<p><b>OBJECTIVE</b>To study the weak loop in the treatment of children with out-of-hospital cardiac arrest (OHCA) and the treatment strategy for improvement.</p><p><b>METHOD</b>Data of a total of 133 patients with OHCA who were rescued by Wuxi pre-hospital care center during the 2005 - 2011 were analyzed.</p><p><b>RESULT</b>The main causes of pediatric OHCA were drowning (52/133) and accidental injury disease (30/133). The cases of OHCA were mainly located in public places (60/133) and the majority occurred in winter and summer. The emergency rescue response time was (13.21 ± 8.09) min, the rate of first witness treatment was 3.91%, intubations was performed in 11.11%, opening of vein access was 23.15% and one case got restoration of spontaneous circulation (ROSC).</p><p><b>CONCLUSION</b>The rate of ROSC of pre-hospital cardiac arrest in children was significantly lower than that of hospital cardiac arrest. Preventive interventions on children's accidents and the skills of pre-hospital staff on pediatric advanced life support (PALS) need to be urgently improved.</p>

Application of enteral nutrition in preoperative bowel preparation for rectal cancer patients undergoing radical operation / 中华胃肠外科杂志

<p><b>OBJECTIVE</b>To explore the feasibility and safety of enteral nutrition in preoperative bowel preparation for rectal cancer patients undergoing radical operation.</p><p><b>METHODS</b>Sixty rectal cancer patients undergoing selective low anterior resection were randomized into the trial group(n=30) and the control group(n=30). Patients in the trial group received clean liquid integral protein diet for 3 days before operation without mechanical bowel preparation. Patients in the control group received traditional diet and mechanical bowel preparation. The intraoperative and postoperative clinical data, the quality of bowel preparation, postoperative complications, and nutritional parameters were compared between the two groups.</p><p><b>RESULTS</b>There were no significant differences in clinicopathological characteristics between the two groups before operation. The operative time, blood loss, quality of bowel preparation as well as postoperative hospital stay were not significantly different(all P>0.05). While the time to first flatus [(2.53±0.91) d vs. (3.03±0.68) d] and semi-liquid diet intake[(3.95±0.83) d vs. (4.52±1.14) d] were significantly shorter in the trial group as compared with the control group(all P<0.05). There were no death and no significant difference in postoperative complications [16.7%(5/30) vs. 20.0%(6/30), P>0.05]. The levels of postoperative total protein, albumin, and prealbumin decreased significantly. Meanwhile, the levels of postoperative albumin[(36.2±2.5) g/L vs. (33.5±2.6) g/L, P<0.01] and prealbumin [(325.4±28.2) mg/L vs. (302.5±34.2) mg/L, P<0.01] in the trial group were significantly higher than those in the control group.</p><p><b>CONCLUSIONS</b>Preoperative enteral nutrition can replace the mechanical bowel preparation with better efficacy, and improve the postoperative nutritional status without increasing surgical risk in rectal cancer patients undergoing radical operation.</p>

Neutrophil-lymphocyte ratio as a prognostic factor in gastric cancer / 中华胃肠外科杂志

<p><b>OBJECTIVE</b>To explore whether neutrophil-lymphocyte ratio (NLR) is an effective prognostic marker in gastric cancer.</p><p><b>METHODS</b>Clinical data of 775 patients with gastric cancer in the First Affiliated Hospital of Sun Yat-sen University from 1994 to 2006 were analyzed retrospectively. According to preoperative NLR, the patients were divided into the low NLR group (NLR≤3.79, n=652) and the high NLR group (NLR>3.79, n=123). The 5-year survival rates of two groups of different TNM stage, different surgical intervention were separately analyzed.</p><p><b>RESULTS</b>The 5-year survival rates in the low NLR group and high NLR group were 44.0% and 12.2% respectively (P<0.01). In different TNM stages: stage I (97.8% vs 33.3%), stage II (55.4% vs 32.0%), stage IIIA (30.2% vs 11.1%), stage IIIB (15.5% vs 8.3%), stage IV (10.7% vs 2.1%), and in different surgical intervention: D1 curative gastrectomy (93.3% 33.3%), D2 group (51.3% vs 20.4%), D3 group (42.4% vs 10.5%), D4 group (14.3% vs 2.0%), and in palliative operation group (8.3% vs 2.2%). There were significant differences of 5-year survival rate in TNM staging and surgical procedures between the high and low NLR groups (all P<0.05).</p><p><b>CONCLUSION</b>Preoperative NLR may be a prognostic marker in patients with gastric cancer.</p>

Comparison of clinicopathological characteristics and prognosis of mucinous and poorly differentiated gastric cancer / 中华胃肠外科杂志

<p><b>OBJECTIVE</b>To investigate the clinicopathological characteristics between mucinous gastric cancer (MGC) and poorly differentiated gastric cancer(PDGC) and factors associated with prognosis.</p><p><b>METHODS</b>Medical records of 1016 consecutive patients with gastric cancer were retrospectively reviewed. Sixty-eight patients with MGC and 508 with PDGC were identified. Clinicopathologic characteristics and overall survival data were analyzed.</p><p><b>RESULTS</b>As compared to PDGC patients, patients with MGC were significantly older [(59.2±11.9) years vs. (54.1±13.2) years], had significantly more distant metastasis(36.8% vs. 23.8%), more peritoneal seeding(29.4% vs. 16.9%), and less radical resection(60.3% vs. 76.6%). There were no significant differences in 5-year survival rate between MGC and PDGC patients(29.4% vs. 35.5%). However, for tumors in the middle third of the stomach, the survival rate of MGC patients was lower than that of PDGC. Using a Cox proportional hazard ratio model, lymph node involvement and radical resection were independent prognostic factors for survival of MGC patients, while tumor invasion, lymph node involvement, and radical resection were associated with survival in patients with PDGC.</p><p><b>CONCLUSION</b>Although MGC and PDGC differ in age, frequencies of peritoneal seeding, distant metastasis, and rate of radical resection, overall survival is comparable.</p>

Efficacy of tyrosine kinase inhibitor therapy combined with surgical resection in patients with metastatic gastrointestinal stromal tumor / 中华胃肠外科杂志

<p><b>OBJECTIVE</b>To investigate the clinical effect of surgery following systemic targeted therapy of tyrosine kinase inhibitors (TKIs) in patients with metastatic gastrointestinal stromal tumors (GIST).</p><p><b>METHODS</b>From June 2007 to December 2009, data of 15 consecutive patients with metastatic GIST treated with imatinib/sunitinib followed by surgery were retrospectively analyzed.</p><p><b>RESULTS</b>Disease responses to TKI treatment was categorized into controlled disease (including partial response and stable disease) (6, 40.0%), limited progression (4, 26.7%), and generalized progression (5, 33.3%), respectively. Surgeries were performed after mean 12 months following TKI therapies. Gross complete resection or optimal debulking with minimal residual disease were managed to performed in 8/10 patients with disease controlled and limited progression, while optimal debulking only achieved in 2/5 patients with generalized progression. Surgical morbidity was 20.0% (3/15). After operation, patients with disease controlled and limited progression had a median progression-free survival of 25.0 months and 2-year overall survival rate of 100%. In contrast, for patients with generalized progression, the median progression- free survival was 3 months (P<0.01), and median overall survival 10.5 months.</p><p><b>CONCLUSIONS</b>Patients with metastatic GIST who have controlled disease or limited progression to TKI therapy can benefit from surgical resection. Surgery should be selective in patients with generalized progression since surgery hardly improves survival in these patients.</p>
