RESUMO
Objective To evaluate the effect of oral compound carbohydrate drinks before operation on the postoperative recovery of gastrointestinal function in the patients undergoing gynecological laparoscopic operation.Methods Ninety American Society of Anesthesiologists physical status Ⅰ or Ⅱ patients,aged 18-64 yr,with body mass index of 18-25 kg/m2,scheduled for elective gynecological laparoscopic operation under general anesthesia,were divided into 3 groups (n =30 each) using a random number table method:routine fasting and water deprivation group (group C),preoperative intravenous infusion of glucose group (group Ⅴ),and oral compound carbohydrate drinks group (group O).In group Ⅴ,5％ glucose solution 8 ml/kg was intravenously injected over 30 min starting from 3 h before operation.In group O,compound carbohydrate drinks 355 ml was given orally within 30 min starting from 3 h before operation.The occurrence of reflux or aspiration,recovery time of bowel sounds and time of passing flatus/defecating time were recorded.The occurrence of nausea,vomiting and bloating was recorded within 48 h after operation.The levels of plasma motilin (MTL) and serum gastrin (GAS) were determined using radioimmunoassay at 6 h before and after operation.The area of gastric antrum was measured before anesthesia induction.Anxiety was assessed using Self-rating Anxiety Scale (SAS) at 1 h before operation and 4 and 24 h after operation.Results No patients developed reflux or aspiration.Compared with group C,the recovery time of bowel sounds and time of passing flatus/defecating time were significantly shortened,the incidence of nausea,vomiting and bloating was decreased,the levels of plasma MTL and serum GAS were increased at 6 h after operation,and SAS scores were decreased at 4 and 24 h after operation in group O,and SAS scores were significantly decreased at 1 h before operation (P＜0.05),and no significant changes were observed in the other indexes in group Ⅴ (P＞0.05).Compared with group Ⅴ,the recovery time of bowel sounds and time of passing flatus/defecating time were significantly shortened,the incidence of nausea,vomiting and bloating was decreased,the levels of plasma MTL and serum GAS were increased at 6 h after operation,and SAS scores were decreased at 1 h before operation and 4 and 24 h after operation in group O (P＜0.05).Conclusion Oral compound carbohydrate drinks 355 ml at 3 h before operation can promote the postoperative recovery of gastrointestinal function without increasing the risk of reflux or aspiration in the patients undergoing gynecological laparoscopic operation.
RESUMO
Objective To evaluate the clinical value and toxicities of docetaxel plus capecitabine in the first-line treatment of metastatic breast cancer (MBC),and compare the outcomes among different molecular subtypes.Methods A total of 108 patients with MBC who received docetaxel plus capecitabine combination treatment between January 1,2012 and December 31,2015 in Bejing Chaoyang District Sanhuan Cancer Hospital were retrospectively analyzed,and 104 cases were available for evaluation.The clinicopathological characteristics,clinical value and toxicities of these patients were evaluated.Results The patients were divided into 3 molecular subtypes,among 104 patients,85 patients in Luminal subtype,14 patients in triple negative breast cancer (TNBC) subtype,and 5 patients in human epidermal growth factor receptor-2 (HER-2) over expression subtype.The treatment achieved objective responses (OR) in 55 patients (52.9％),and the disease control rate (DCR) was 88.5％,including complete response (CR) in 4 patients,partial response (PR) in 51 patients,stable disease (SD) in 37 patients,and progressive disease (PD) in 12 patients.In Luminal subtype,4 patients achieved CR,43 PR,33 SD,and 5 PD.In TNBC subtype,6 patients achieved PR,3 SD,5 PD.In the HER-2 over expression subtype,2 patients achieved PR,1 SD,2 PD.There was no significant difference in the short-term therapeutic effect among 3 molecular subtypes (x2 =4.429,P =0.106).As a result,the progression-free survival (PFS) of the 104 patients was 1.5-121.0 months,and the median PFS was 10.0 months.The median PFS was 11.0 months in Luminal subtype,4.0 months in TNBC subtype and 10.3 months in HER-2 over expression subtype,with a significant difference (x2 =7.510,P =0.006).The most common adverse events were hand-foot syndrome (HFS),nausea or vomiting,neutropenia,anaemia,diarrhea and so on.The incidence of grade 2/3 HFS was 44.2％ (46/104),and the grade 3/4 neutropenia was 39.4％ (41/104).Conclusion The first-line treatment of MBC using docetaxel plus capecitabine is effective,and the toxicities can be tolerable,especially in the Luminal subtype.
