OBJECTIVETo evaluate the effect of nasogastric decompression tube after gastric cancer operation on the postoperative recovery.
METHODSA total of 174 patients with gastric cancer were prospectively enrolled from December 2009 to March 2011 and randomly divided into non-nasogastric tube control group(n=88) and nasogastric tube group(n=86). Postoperative symptoms, complications, recovery time, and quality of life during hospital stay were compared between the two groups.
RESULTSThe incidences of nausea(14.8% vs. 47.7%, P<0.01), sore throat(6.8% vs. 38.4%, P<0.01), bucking and foreign body sensation(3.4% vs. 20.9%, P<0.01), expectoration obstruction(36.4% vs. 55.8%, P<0.05) were significantly lower in nasogastric tube group than those in the control group. The intervals to ambulation and flatus were(1.46±0.58) d and(3.11±0.77) d in the non-nasogastric tube group, significantly shorter those in nasogastric tube group[(1.68±0.61) d and(3.75±1.03) d]. There was no anastomotic leak or bowel obstruction. The difference in bleeding was not statistically significant[3.4%(3/88) vs. 5.8%(5/86), P>0.05] between the two groups. The quality of life differed between the two groups(mean score, 3.36 vs. 2.78, P<0.01).
CONCLUSIONEarly removal of nasogastric decompression tube is safe and reasonable and can improve the quality of life during hospital stay.

Objective To assess the treatment efficacy and safety of lanthanum carbonate (LC) in patients on maintenance hemodialysis. Methods MEDLINE (1996—2014), Embase (1974—2014.12), Pubmed (1996—2014.12), Cochrane library, Chinese Wanfang database (1996—2014.12) and CNKI (1979—2014.12) were searched. Lanthanum carbonate and hemodialysis were used as Chinese and English search terms respectively, and the articles met the inclusion and exclusion criteria were used as supplements. Quality assessment and data mining were conducted by two independent investigators who performed Meta-analysis using RevMan5.2. Results Nine trials with 2 674 participants were included in this study. The Meta-analysis showed that there were similar blood levels of calcium [WMD=-0.24,95%CI:(-0.61)-0.14, P=0.21], phosphorus [WMD=0.14,95%CI:(-0.02)-0.30,P=0.08] and phosphate control rates (RR=0.91,95%CI:0.70-1.17, P=0.44) between control group and lanthanum carbonate group. There were lower incidence rates of hypercalcemia (RR=0.17, 95%CI:0.06-0.47, P=0.000 7) and blood levels of calcium-phosphorus product [WMD=-2.17,95%CI:(-3.99)-(-0.35), P=0.02], and higher levels of parathyroid hormone (iPTH, WMD=105.69, 95%CI:70.38-141.00, P<0.000 01) and bone-specific alkaline phosphatase (BAP, WMD=6.47, 95%CI:0.43-12.50, P=0.04) in these two groups. There were no significant differences in incidence rates of gastrointestinal adverse events between two groups. Conclusion Lanthanum carbonate should be used as preferred choice of phosphate binders to control serum phosphorus in patients on maintenance hemodialysis.

Objective To evaluate the effect of continuous renal replacement therapy (CRRT) on the remove of inflammatory mediators and the function of endothelial cells in patients with multiple organ dysfunction syndrome (MODS). Methods Thirty patients with MODS were enrolled in this study. All of the patients underwent CRRT for at least 24 hours. Peripheral blood levels of IL-1β, IL-4, IL-6, IL-10, TNF-α, E-selectin, sVCAM-1, slCAM-1 and PAF-AH were measured at the beginning and 3, 6, 12, 24 h after initiation of CRRT. Results Nineteen patients survived after 14 days and 17 patients survived after 28 days during therapy. The clinical oxygenation and bemodynamics were improved after 6 h of CRRT. Among inflammatory mediators, the levels of TNF-α, IL-6, IL-10 rose gradually from the beginning [(462.24±331.03) ng/L, (106.39±90.82) ng/L, (124.51±118.39) ng/L), and reached the peak at 12 h [(887.88±975.46) ng/L, (132.01±118.14) ng/L, (167.01±161.66) ng/L], and the levels of IL-1β, IL-4 decreased from initiation of CRRT. But there were no significant differences in the levels of above cytokines between at the beginning and at the end of CRRT. There were significant differences in the levels of cytokines between survival and death group. The level of IL-6 in death group [(145.45±14.28) ng/L] was significantly higher than that in survival group [(106.03±10.86) ng/L]. The level of IL-10 in death group [(94.93±16.09) ng/L] was significantly lower than that in survival group [(143.06± 12.24) ng/L]. Levels of E-select, sVCAM-1 and sICAM-1 elevated from the beginning and reached the peak at 12 h, but no significant differences were found between intiation and the end of CRRT. The level of PAF-AH increased after initiation, and there was a significant difference between beginning and the end of CRRT. Levels of cytokines for endothelial cell function were significantly different, such as E-selectin [(287.13±42.70) μg/L vs (266.26±65.26) μg/L], sVCAM-I [( 1697.25± 475.24) μg/L vs (1488.10±691.67) μg/L], sICAM-1 [(975.33±142.50) μg/L vs (835.40±332.41) μg/L], and PAF-AH [(9.07±6.38 ) μg/L vs (16.32±8.95)μg/L]. Conclusions Clinical oxygenation and hemodynamics can be improved, and endothelial cell function can be improved partly by CRRT. There were no significant differences of inflammatory mediator levels between initiation and the end of CRRT. IL-6 and IL-10 can be used as predicators for prognosis of MODS patients.
