Objective To investigate whether Ivor-Lewis esophagectomy combined with adjuvant radiotherapy prevents lymphatic metastatic recurrence in esophageal cancer patients.Methods 113 Stage Ⅱ A esophageal squamous cell carcinoma patients after Ivor-Lewis esophagectomy were accpected mRNA expression of Mucin1 gene detection.Positive patients were enrolled into adjuvant radiotherapy group(with postoperative adjuvant radiotherapy).Negative patients were enrolled into control group (without postoperative adjuvant radiotherapy or chemotherapy).The radiotherapy area consisted of the neck,supraclavicular region and the superior mediastinum(including praesophageal and pratracheal region).Survival difference was compared by x2 test,the Kaplan-Meier method was performed to calculate the survival rate and recurrence rate.Logistic regressive analysis was performed to determined independent risk factors.Results The radiotherapy area lymphatic metastatic recurrence rate in adjuvant radiotherapy group(16.7％,5/30) was lower than patients without postoperative adjuvant radiotherapy (45.8％,38/83) (P ＜ 0.05).Only compared to positive patients without postoperative adjuvant radiotherapy(60.0％,6/10),the rate (16.7％,5/30) was significantly lower(P ＜ 0.01).Cancer recurrence was recognized in 48.6％ (55/113) patients within 3 year after operation,including 38.1％ (43/113) patients with radiotherapy area recurrence.In logistic analysis the T status (P＜ 0.01) and adjuvant radiotherapy (P ＜ 0.05) were independent risk factors of lymph node metastasis in the first 3 years after operation.Conclusion In Mucin1 mRNA-positive esophageal squamous cell carcinoma patients,adjuvant radiotherapy could significantly reduce the lymph node metastasis rate in the radiotherapy area after Ivor-Lewis esophagectomy.Compared with traditional therapeutic methods,Ivor-Lewis esophagectomy combined with adjuvant radiotherapy can achieve similar curative effects in Mucin1 mRNA-positive patients.

Objective To describe the level of self-perceived burden (SPB) and analyze its influencing factors among the patients with advanced lung cancer, in order to provide a theoretical basis for individualized nursing care. Methods A total of 102 hospitalized patients with lung cancer from 3 hospitals in Shandong province were investigated by the Self-Perceived Burden Scale for Cancer Patient (SPBS-CP). Results The total score of the SPBS-CP was (60.31±17.06) points, which indicated at a moderate level. Those patients rated the highest score on the sub-scale of economic/family burden (22.04±6.72) points, the lowest score on the sub scale of care burden (10.28±3.62) points. Single factor analysis and regression results showed that different work conditions, different stages were related with SPB. Conclusions Patients with moderate and advanced lung cancer had a moderate or higher level of SPB. Staff nurses should focus on the psychological status of the patients and take positive interventions to release the negative emotional experiences.

AIM: To investigate the protective effect and mechanism of quercetin on age-related macular degeneration in mice through Nrf2/Keap1/ARE pathway.

METHODS: Kunming mice were used as research objects, which were divided into control group, model group and quercetin group. Fundus examination was showed whether yellow-white like glassy sputum substances appeared in the fundus of each group of mice; OCT was used to examine the retinal thickness of each group of mice; HE staining was used to observe the changes of retinal morphology in each group of mice; FFA was observed the fundus vascular integrity of each group of mice. The activities of SOD, GSH-Px, CAT and the contents of ROS and MDA in serum were detected by ELISA; Western blot was used to detect the expression of Nrf2/Keap1/ARE related proteins in the retina of each group.

RESULTS: Quercetin can reduce the yellow and white glassy wart substance in the fundus of mice and increase the thickness of the retina(P<0.05), and the points of retinal vascular leakage is significantly reduced. Compared with the model group, the a-wave amplitude and b-wave amplitude of the quercetin group were significantly higher than those of the model group(P<0.01); Quercetin can make the retinal structure of mice clearer, necrosis and shed part of the outer nuclear layer, and reduce the content of ROS and MDA in mouse serum(all P<0.05), and increase the activities of SOD, GSH-Px, and CAT(all P<0.05). Compared with the model group, the expression of Nrf2 protein in the retinal cytoplasm of mice in the quercetin group was up-regulated(P<0.05), and the expression of Nrf2 protein in the nucleus was down-regulated(P<0.05), GCL protein expression was down-regulated(P<0.05).

CONCLUSION: Quercetin improved the oxidative stress state after retinal photodamage through the Nrf2/Keap1/ARE pathway, protected the retinal function, and protected against age-related macular degeneration.

This is a study based on hospital intensive monitoring to explore medication use of Diemailing Kudiezi injection(one Chinese herbal medicine injection) in real word in the patients with cerebral infarction. The active monitoring model was adopted and hospital intensive monitoring on safety of 7 189 cases of patients with cerebral infarction was conducted to obtain the drug use information of Diemailing injection. The results were analyzed by using statistical description and association rule method. The statistical description and association rule analysis were conducted based on patients' basic demographic characteristics, use of Diemailing injection and combined use of drugs. Sixty-two percent(4 437/7 189) of the patients were from traditional Chinese medicine hospitals as compared with 39%(2 752/7 189) from western medicine hospitals; 84%(6 003/7 189) of the patients were from tertiary hospitals as compared with 16%(1 186/7 189) from second-class hospitals. The hospitals were mostly located in north China. Drug related indicators such as a single dripping speed, stash time after allocating transfusion, duration of injection, and injecting room temperature were not noted in instruction manual. It was also found that there were off label use in the practice, for instance, non-intravenous infusion, >14 d treatment course, use of non-designated solvent, and a single dose>40 mL or<10 mL. Analysis of association rules showed that only Edaravone among the most frequent combined drugs was listed in the current guideline in China, and the other three most frequent combined drugs deproteinized calf blood extractive injection, Cinepazide Maleate injection and Alprostadil injection were used with little evidence. Diemailing＋Aspirin＋Alprostadil was the most common combined use in our study, but the recommended clopidogrel＋Aspirin was not found in this study. The drug use situation of Diemailing injection in the real world was obtained by data analysis on large size samples, providing basic reference information for clinicians and researchers. However, efficacy was not concerned in this study, so efficacy-related information could not be explained.

Objective::To study the protective effect and mechanism of Qidong Yixin oral liquid on doxorubicin-induced myocardial toxicity in mice. Method::Ninety male ICR mice were randomly divided into normal group, model(DOX) group, DOX+ Qidong Yixin oral liquid group (9.55, 23.88, 47.75 g·kg^-1) and high dose group (47.75 g·kg^-1) with 15 mice in each group. The normal group and model group were given pure water by gavage, and each dose group of Qidong Yixin oral liquid was given different doses of Qidong Yixin oral liquid once a day for 21 days. On the seventh day, normal saline was injected into the abdominal cavity of the normal group and the high dose group of Qidong Yixin oral liquid. Doxorubicin was injected into the abdominal cavity of the other groups (15 mg·kg^-1). After 21 days, the weight and heart weight of mice were weighed and cardiac index was calculated. Serum was taken for the detection of lactate dehydrogenase (LDH), creatine kinase (CK), aspartate aminotransferase (AST). Heart was taken for hematoxylin-eosin (HE) staining, superoxide dismutase (SOD), glutathione peroxidase (GSH-PX), catalase (CAT) in myocardial tissue were detected. The expression of nuclear factor NF-E2 related factor (Nrf2) and heme oxygenase-1 (HO-1) were detected by Western blot. Result::Compared with normal group, adriamycin could significantly reduce the body weight of mice (P<0.01), increase the activities of LDH, CK and AST in serum(P<0.01), and decrease the activities of antioxidant enzymes (P<0.01). Compared with DOX group, high dose Qidong Yixin oral liquid could significantly increase the weight of mice (P<0.05, P<0.01), decrease the level of myocardial three enzymes(P<0.01), increase the activity of antioxidant enzymes(P<0.05, P<0.01), and increase the expression of Nrf2 and HO-1(P<0.01). Conclusion::Qidong Yixin oral liquid has a good protective effect on doxorubicin myocardial toxicity. Its mechanism may be related to activating Nrf2/HO-1 signaling pathway and alleviating oxidative stress injury.
