Objective To explore the effect of artificial nasal feeding mode on the consciousness obstacle of stroke patients with nasogastric tube.Methods From November 2010 to July 2012,50 patients with consciousness disorder and nasogastric tube in the ward of neurology department were enrolled in the study.The routine and artificial nasal feeding methods were performed on odd days and even days respectively.Then,bowel sound frequency,the incidence of reflux were observed and analyzed.Results The incidence of gastroesophageal reflux in the artificial nasal feeding mode group was significantly lower than that in the routine artificial feeding method group (14.7％ vs 33.8％ ; x2 =20.718,P ＜ 0.01).And patients had significantly different incidence of reflux with different bowel sound frequency (x2 =51.824,P ＜ 0.01).Conclusions The incidence of reflux is negatively correlated with the bowel sound frequency.And application of the artificial nasal feeding mode on consciousness obstacle of stroke patients with nasogastric tube can reduce the incidence of gastro-esophageal reflux.

[Abstrca t] Objective BRCA 1 ( breast cancer susceptibility gene 1) and RAP80 ( receptor-associated protein 80) play key roles in predicting chemosensitivity of platinum and taxanes .A randomized trial was carried out to compare non-selected cisplatin-based chemotherapy with therapy customized according to BRCA1 and RAP80 expression.Methods Advanced stage NSCLC patients whose tumor specimen was sufficient for molecular analysis were randomized (1∶3) to the control or experimental arm.Patients in the control arm received docetaxel/cisplatin; in the experimental arm , patients with low RAP 80 expression received gemcitabine/cisplatin ( Arm 1 ) , those with intermediate/high RAP 80 expression and low/intermediate BRCA 1expression received docetaxel/cisplatin ( Arm 2 ) , and those with intermediate/high RAP80 expression and high BRCA1 expression received docetaxel alone (Arm 3).The primary end point was progression-free survival (PFS).Results 226 patients were screened and 124 were randomized in this trial.ORR in the four subgroups was 22.6%, 48.4%, 30.3%and 19.2%, respectively (P=0.08);PFS was 4.74, 5.59, 3.78 and 2.73 months, respectively (P=0.55); and OS was 10.82, 14.44, 10.86 and 10.86 months, respectively (P=0.84).The common adverse effects included neutropenia , nausea, anemia and fatigue.Conclusions No statistically significant difference of ORR , PFS or OS is observed in the experimental arms compared with the control arm .Patients with low RAP 80 mRNA levels have a trend of better survival and higher response rate to gemcitabine /cisplatin chemotherapy .
