Objective To explore the effect of triple viable bifidobacterium lactobacillus tablets combined with polyethylene glycol 4000 on elderly patients with chronic constipation. Methods This pilot study was conducted at the Center of Gerontology and Geriatrics, West China Hospital. A total of 120 patients with chronic constipation, aged 60 years or older, treated between April 2015 and April 2016 were enrolled, and randomly assigned into group A (polyethylene glycol 4000) and group B (triple viable bifidobacterium lactobacillus tablets combined with polyethylene glycol 4000) with 60 patients in each. All the patients were estimated before and after the treatment with Bristol Stool Form Scale (BSFS), Patient Assessment of Constipation Symptom (PAC-SYM) and Constipation Related Disability (CRDS), and the adverse drug reactions were observed. Results In group A, before the treatment, the scores of BSFS, PAC-SYM and CRDS were 1.98±0.77, 37.87±4.12 and 31.03±3.19, respectively; while after the treatment, the scores were 3.87±0.82, 28.55±2.15 and 18.56±1.80, respectively, which were all significantly improved (P<0.05). In group B, before the treatment, the scores of BSFS, PAC-SYM and CRDS were 2.03±0.78, 36.25±4.98 and 30.28±3.56, respectively; while after the treatment, the scores were 4.80±0.75, 19.73±3.42 and 13.80±2.36, respectively, which were all significantly improved (P<0.05). The improvement of constipation in group B was significantly better than that in group A after treatment (P<0.05). There was no adverse drug reaction observed. Conclusion Triple viable bifidobacterium lactobacillus tablets combined with polyethylene glycol 4000 may be an effective therapy for elderly patients with chronic constipation.
【摘要】 目的 评价生长抑素联合中药在治疗重症急性胰腺炎中的有效性。 方法 应用国际Cochrane协作网系统评价方法对生长抑素联合中药治疗重症急性胰腺炎的随机对照试验（RCT）进行系统评价。计算机检索MEDLINE（Ovid）、PubMed数据库、中文科技期全文数据库（VIP）、万方数据库、中国期刊全文数据库（CNKI）、中国生物医学文献数据库（CBM）。检索时间均为建库至2009年9月。文献检索语种为英语和中文。 结果 共纳入8个RCT，436例患者，所有纳入试验在治疗末均未进行随访。Meta分析结果显示，生长抑素联合中药治疗组（治疗组）的病死率（13/188，6.9%）明显低于单纯生长抑素治疗组（对照组）（24/174，13.7%），差异有统计学意义[Peto OR=0.46，95%CI（0.22，0.94），Plt;0.05]。治疗组平均住院日低于对照组[WMD=-7.01，95%CI（-7.89，-6.13），Plt;0.000 01]。治疗组腹痛缓解时间明显低于对照组，其差异有统计学意义[WMD=-0.77，95%CI（-0.82，-0.72），Plt;0.000 01]。治疗组与对照组治疗第7天APACHE Ⅱ评分均下降，治疗组下降幅度大于对照组，两组比较差异有统计学意义（Plt;0.05）。治疗组并发症发生率（26/91，28.6%）与对照组（35/88，39.8%）相比，其差异无统计学意义[Peto OR=0.61，95%CI（0.32，1.13），P=0.12]。 结论 生长抑素联合中药治疗在改善重症急性胰腺炎的病死率、平均住院时间、腹痛缓解时间、APACHE Ⅱ评分下降幅度优于单纯生长抑素治疗。
ObjectiveTo investigate the relationship between the expression of programmed cell death ligand-1 (PD-L1) and the maximal standardized uptake value (SUVmax) in 18F-fluorodeoxyglucose (FDG) positron emission tomography/computed tomography (PET/CT) and the correlation of clinical factors between SUVmax values and PD-L1.MethodsThe clinical data of 84 patients with invasive lung adenocarcinoma diagnosed pathologically in West China Hospital, Sichuan University from August 2016 to November 2018 were analyzed retrospectively, including 38 males and 46 females, aged 60 (32-85) years. The tumor was acinar-predominant in 37 patients, papillary in 20, lepidic in 19, solid in 5 and micropapillary in 3. Multivariate analysis of the relationship between SUVmax value and other clinicopathological features was performed by linear regression. Logistic regression analysis was used to analyze the relationship between PD-L1 protein expression and other pathological features.ResultsThe SUVmax of the PD-L1 expression group was significantly higher than that of the non-PD-L1 expression group in the whole invasive lung adenocarcinoma group (P=0.002) and intermediate-grade histologic subtype (P=0.016). The SUVmax cut-off value of PD-L1 expression in the whole invasive lung adenocarcinoma group and intermediate-grade histologic subtype was 5.34 (AUC: 0.732, P=0.002) and 5.34 (AUC: 0.720, P=0.017), respectively. Multivariate analysis showed that pleura involvement, vascular tumor thrombus and the increase of tumor diameter could cause the increase of the SUVmax value, while the SUVmax value decreased in the moderately differentiated tumor compared with the poorly differentiated tumor. The SUVmax cut-off value between low-grade histologic subtype and intermediate-grade histologic subtype, intermediate-grade histologic subtype and high-grade histologic subtypes was 1.54 (AUC: 0.854, P<0.001) and 5.79 (AUC: 0.889, P<0.001), respectively. Multivariate analysis of PD-L1 expression showed pleura involvement (P=0.021, OR=0.022, 95%CI 0.001 to 0.558) and moderate differentiation (opposite to poor differentiation) (P=0.004, OR=0.053, 95%CI 0.007 to 0.042) decreased the expression of PD-L1.ConclusionThe SUVmax of the PD-L1 expression group is significantly higher than that of the non-PD-L1 expression group in the whole invasive lung adenocarcinoma group and intermediate-grade histologic subtype. The level of SUVmax and the expression of PD-L1 in invasive lung adenocarcinoma are related to many clinical factors.
