Immunotherapy is an important treatment method in tumor therapy. Among them, programmed death-1/programmed death ligand-1 inhibitors are the immune preparations with mature application and great survival benefit at present. Programmed death-1/programmed death ligand-1 inhibitors brought better clinical benefits to patients with esophageal cancer and provided more favorable choice for the treatment of esophageal cancer. This article introduces the mechanism of action, application in esophageal cancer, and efficacy predictors of programmed death protein-1/programmed death protein ligand-1 inhibitors, aiming to provide a theoretical basis for the more rational use of programmed death protein-1/programmed death protein ligand-1 inhibitors in patients with esophageal cancer.
Abstract： Objective To compare clinical outcomes and postoperative quality of life （QOL） of difference surgical strategies for patients with esophagogastric junction （EGJ） cancer， and investigate the best surgical strategy. Methods A total of 148 patients with EGJ cancer underwent surgical treatment in Xuzhou First People’s Hospital from July 2007 to October 2011. There were 111 male patients and 37 female patients with an average age of 64 （47-77）years. All the patients were divided into 3 groups according to different surgical strategies for them based on their respective preoperative assessment and tumor invasion degree. In group A， 81 patients underwent proximal subtotal gastrectomy and subaortic gastroesophageal anastomosis. In group B， 20 patients underwent total gastrectomy and esophagojejunostomy. In group C， 47 patients underwent proximal subtotal gastrectomy and jejunal interposition. Postoperative mortality and morbidity were compared among the three groups. Cancer metastasis rate and 1-year survival rate were also compared among the three groups. QOL questionnaire （EORTC QLQ C-30 and tumor specific module QLQ-OES24） was used to evaluate patients’ QOL during follow-up. Results There was no statistical difference in postoperative morbidity （P=0.762）and mortality （P=0.650）among the three groups. There was no statistical difference in cancer metastasis rate at 1 year after surgery among the three groups （P=0.983）. One-year survival rate was 100% in all the three groups. At 1 year after surgery， physical functioning score （P=0.037，0.000） and global health score （P=0.035，0.006） of group A and group C were significantly higher than those of group B， and there was no statistical difference in physical functioning score and global health score between group A and group C （P＞0.05）. Emotional function score of group B was significantly lower than that of group C （P=0.015）. Fatigue score （P=0.040，0.006）， anorexia（P=0.045，0.025）， nausea and vomiting symptom score （P=0.033，0.048） of group A and group C were significantly lower than those of group B. Pain score of group A was significantly lower than that of group C （P=0.009）. Insomnia score of group A was significantly higher than that of group C （P=0.028）. Reflux score of group A was significantly higher than that of group B and group C （P=0.025，P=0.021）. Conclusion Postoperative QOL in patients with EGJ cancer who undergo total gastrectomy is comparatively unsatisfactory. Proximal subtotal gastrectomy and jejunal interposition can significantly improve postoperative QOL. Postoperative QOL evaluation is helpful to choose better surgical strategies for patients with EGJ cancer.
Objective To evaluate the efficacy and safety of traditional Chinese medicine(TCM) paste in treating chronic obstructive pulmonary disease (COPD) in stable stage. Methods We electronically searched databases including PubMed, EMbase, The Cochrane Library (Issue 12, 2016), VIP, WanFang Data, CNKI and CBM to collect randomized controlled trials (RCTs) regarding TCM paste in combination with conventional Western therapy versus Western therapy alone in treating stable COPD from inception to December 2016. Two reviewers independently screened literature, extracted data and assessed the risk of bias of the included studies. The meta-analysis was conducted by RevMan 5.3 software. Results A total of 9 RCTs involving 605 Chinese patients were included. The results of meta-analysis showed that: when compared with conventional Western medicine alone, TCM paste combined with the conventional Western medicine significantly improved clinical effective rate (RR=1.20, 95% CI 1.10 to 1.31,P<0.000 1), decreased SGRQ score (MD=–4.53, 95% CI –5.41 to –3.65,P<0.000 01) and CAT score (MD=–2.45, 95% CI –3.38 to –1.51,P<0.000 01), increased FEV1% (MD=3.80, 95% CI 0.40 to 7.20,P=0.03), and reduced the frequency of acute exacerbation (P<0.05). No serious adverse reaction occurred in both groups. Conclusion The current evidence shows that combination of TCM paste and conventional Western medicine may improve clinical effective rate, quality of life, increase FEV1%, and reduce the frequency of acute exacerbation in patients with stable COPD. Due to the limited quality and quantity of included studies, the above results are needed to verify by more studies.
Objective To analyze the clinical characteristics of the Guang’an Omicron epidemic and summarize the management experiences and practices in pandemic prevention and control of major infectious diseases.Methods Retrospective analysis was performed on patients infected with coronavirus disease (COVID-19), afterwards treated and observed in the isolation ward of Guang’an People’s Hospital and the shelter of Guang’an City from May 9 to June 26, 2022. The characteristics of patients at different age stages and the related factors affecting the severity, re-positive and negative conversion was analyzed. Results Finally 1 278 patients were collected, including 508 males and 770 females, with an average age of 41.3±22.6 years. Among them, 1 054 patients were asymptomatic carriers. The overall severe rate was 0.86%, the severe rate of the high-risk group was 3.06%. The median negative conversion time was 10.0 days and re-positive rate was 7.36%. Patients aged＞60 years were 2.589 times more likely to have a longer negative conversion time than those aged≤60 years (95%CI 1.921-3.489, P＜0.001). Conclusion The clinical characteristics of Guang’an COVID-19 epidemic are mainly that the elderly with high risk factors are more likely to develop severe cases, have longer clearance time, and re-positve is more likely to occur.
