Objective To study the nutritional status in different age patients with esophageal cancer during radiotherapy. Methods Ninety nine patients with esophageal carcinoma accepted radiotherapy in Zhejiang Cancer Hospital from June 2012 to August 2013 were enrolled. Patients were divided into two groups by their age: the younger age<60 years; and the older age ≥60 years. Nutritional status was measured weekly during radiotherapy, and European Nutritional Risk Screening (NRS) 2002 were used to evaluate the risk of malnutrition. Results The malnutritional incidence during radiotherapy was 23.5%-29.4% and 33.8%-49.2% in the younger group and the older group, respectively. Compared with baseline nutritional parameters, triceps skinfold thickness (TSF) of the<60 years group started to differ at the first week after the start of radiotherapy (first week to the sixth week:9.14±8.67;7.80±2.90;7.62±2.83;7.56± 2.79;7.90±2.91;7.36±2.67, respectively, all P<0.01);compared with baseline nutritional parameters(2.09± 1.28), ≥60 years group started to differ at the second week (2.34 ± 1.24, P<0.05) after the start of radiotherapy for NRS2002 the third week, 2.49 ± 1.24, P=0.016;the fourth week, 2.51 ± 1.30;P=0.013, the fifth week, 2.55 ± 1.29, P=0.006; the sixth week, 2.57 ± 1.26, P=0.004. There was no significant difference between each time point for TSF in>60 years group (P>0.05). No significant difference was found for body mass index (BMI), arm circumference (AC), arm muscle circumference (AMC) in each group (P>0.05). Conclusion The elderly patients with esophageal cancer had significantly increased risk of malnutrition and decreased nutritional status than the younger patients during radiotherapy. Early start of nutrition interventions in the elderly patients may be benefitted.

This article was aimed to study the protective effects and mechanism of resveratrol (Res) on endothelial injury induced by atherosclerosis ( AS ) . Lysophosphatidylcholine ( LPC ) was applied to induce the model of injured endothelial cells. Flow cytometer was used to detect the rate of cell apoptosis. TUNEL staining was used to detect the cell apoptosis. MTT colorimetric test was used to detect the cell viability. Automatic biochemistry analyzer was used to measure the LDH level . ELISA was used to detect TNF-α level . RT-PCR was used to determine the mRNA levels of calcitonin gene-related peptide (CGRP). The results showed that Res with the concentration of 20 μmol/L can effectively slow down the degree of endothelial cell injury induced by LPC which caused the cell disability, high LDH level and high TNF-α level (P < 0.01). Res showed effects on mRNA expression of CGRP. It was concluded that Res can protect against endothelial injury induced by AS, the mechanism of which may be associated with accelerating CGRP synthesis and release by activating VR1.

Objective To investigate the acute myocardial infarction (AMI) patient's electrocardiogram appearing fragment QRS wave (fQRS) and brain natriuretic peptide (BNP) level and scope of coronary lesions,severe cardiac complications,and the cor relation of cardiac death.Methods For selected patients with AMI,whether based on electrocardiogram (ECG) appeared in fQRS group and non fQRS groups; immunofluorescence technique was used to detect the plasma BNP level in patients with AMI.Two groups of patients with serious cardiac events and coronary artery lesions scope were observed; Coronary artery lesion count and BNP level were recorded.Results The incidence of fragment QRS wave in patients with AMI was 34.0％,fQRS wave group height/three degree atri oventricular block,ventricular tachycardia/ventricular fibrillation,cardiac shock,cardiac death rate was higher than non fQRS wave group (P ＜0.05).fQRS wave group of plasma BNP and left ventricular end-diastolic diameter,the double branch lesion,multivessel lesions were significantly higher than that of non fQRS group (P ＜ 0.01) ; left ventricular ejection fraction,the single lesion was sig nificantly lower than non fQRS wave group (P ＜0.01).The BNP levels in single,double,and multivessel lesions in the group with the increase of the lesion count were increased.Conclusions The AMI patients with fQRS easily complicated with severe arrhythmia,and case fatality rate was high,the prognosis was poor.fQRS on electrocardiogram (ECG) and BNP level had a certain relationship with range and degree of coronary artery lesions,degree of indexes might be used as a prediction of coronary lesions,and multivessel lesions had certain prediction value.

Objective To evaluate the therapeutic effect of modifiedHuanglian-Jiedudecoction for resistant hypertension and explore its possible mechanism.Methods A total of 90 patients with resistant hypertension were recruited and randomly divided into a treatment group and a control group, 45 patients in each group. The control group was treated with oral administration of irbesartan and hydrochlorothiazide tablets and controlled-release nifedipine tablets, while the treatment group was further added modifiedHuanglian-Jiedu decoction for 4 weeks. Plasma endothelin (ET) and calcitonin gene-related peptide (CGRP) were measured by radioimmunoassay.Rusults The total efficiency according to the TCM syndrome in the treatment group was 86.7%(39/45) which was higher than 64.4%(29/45) in the control group(χ2=4.873,P=0.027). The systolic blood pressure (SBP) and diastolic blood pressure (DBP) decreased after the treatment in both groups ( SBP in the treatment group: 119.26 ± 9.34 mmHgvs.172.11 ± 10.52 mmHg,t=25.201,P<0.01; DBP in the treatment group: 78.18 ± 7.21 mmHgvs.111.12 ± 11.16 mmHg,t=16.631, P<0.01; SBP in the control group: 145.21 ± 7.56 mmHgvs.171.32 ± 11.15 mmHg,t=13.002,P<0.01; DBP in the control group: 93.57±8.13 mmHgvs. 109.89 ± 12.21 mmHg,t=7.463,P<0.01), while the decrease of SBP (t=14.487,P<0.01) and DBP (t=9.501, P<0.01) in the treatment group was more greater than those in the control group. The control rate of blood pressure in the treatment and control groups were 73.3% (33/45) and 55.6% (25/45), respectively, there had no significant difference (χ2=2.376,P=0.123). The plasma ET in the treatment group was significantly decreased than that in the control group (75.68 ± 10.67 ng/Lvs.112.79 ± 12.26ng/L;t=15.317,P<0.05), and CGRP significantly increased (49.87 ± 4.75 ng/Lvs.33.87 ± 7.89 ng/L;t=11.654,P<0.05).Conclusion Modified Huanglian-Jiedudecoction may have some therapeutic effect for resistant hypertension, its mechanism may be involved in ET decreasing and CGRP increasing.

Objective To evaluate the nutritional status and risks in elderly patients with esophageal cancer during their radiotherapy; to provide the evidence of nutritional assessment tools and interventions in clinical practice. Methods This retrospective study investigated 65 patients with esophageal cancer ( >60 years) who had undergone radiotherapy in Zhejiang Cancer Hospital from June 2012 to August 2013. Nutritional status was assessed at the beginning and after the radiotherapy in every week; nutritional risks were screened every week with the help of NRS 2002. Results Compared with the status at the beginning of radiotherapy, the significant higher nutritional risk emerged: in the second week of the radiotherapy with NRS2002 [(2. 34 ± 1. 24) vs (2. 09 ± 1. 28);Z=3. 234, P<0. 01];the second week with body mass index (BMI) [(20. 21 ± 3. 03) vs (20. 51 ± 3. 06); t=3. 626,P<0. 01]; the third week with arm circumference (AC) [(24.69 ±2.87) vs (24.96 ±2.93);t=2.456,P<0.05]. The differences of triceps skinfold (TSF) and arm muscle circumference (AMC) had no significance (P>0. 05). The incidence of malnutrition during radiotherapy was 33. 8% -49. 2%; the score of NRS2002 was negatively correlated with BMI, TSF, AC and AMC. Nutritional support were provided to 62(93. 8%)patients, three (4. 8%) of the patients received enteral nutrition (EN), 59 (95.2%) patients received parenteral nutrition (PN). Conclusions The risk of malnutrition is high in elderly patients with esophageal cancer and will even worse with the process of radiotherapy. NRS2002 can precisely detect nutritional risks and provide the evidence of nutritional interventions in clinical practice.

Objective To investigate the current status of job satisfaction,stressful events and self-efficacy among nurses in cancer hospital,and explore correlation among job satisfaction,stressful events and self-efficacy.Methods Totally 260 nurses from Zhejiang Cancer Hospital were inquired by Minnesota satisfaction questionnaire,inventory of stressful events,and general self-efficacy scale.Descriptive analysis and Pearson correlation analysis were adopted to analyze the data.Results A total of 260 questionnaires were given out,while 246 valid questionnaires returned,and the effective rate was 94.6％.The total average scores of job satisfaction,stressful events and self-efficacy were (3.41 ± 0.45),(117.72 ± 18.92) and (2.50 ± 0.44).There was a significant negative correlation between overall satisfaction and stressful event (r =-0.458,P＜0.001).However,satisfaction were positively correlated with self-efficacy (r =0.257,P =0.020).Conclusions Job satisfaction among nurses of cancer hospital is higher than data of previous studies,but the overall self-efficacy is still low,and most of them is in the middle-high stressful events.Managers can improve nurses' job satisfaction by reducing occupational stress and increasing self-efficacy.That might reduce dimission rate,and maintain the stability of care team.

Objective To compare the clinical significance of peripheral blood neutrophil to lymphocyte ratio (NLR) and platelet to lymphocyte ratio (PLR) in predicting prognosis of patients with hepatocellular carcinoma (HCC).Methods The clinical data of 661 patients with HCC were retrospectively analyzed.Routine peripheral blood test results were used to calculate the NLR and PLR,and the receiver operating characteristic (ROC) curves were drawn.Using the thresholds of NLR and PLR,the patients were divided into the low NLR group and the high NLR group,and the low PLR group and the high PLR group.Overall survival (OS) and disease free survival (DFS) were evaluated by the Kaplan-Meier method.Independent prognostic predictors were determined by the Cox proportional hazard model.Results The NLR and PLR thresholds were 2.790 and 99,respectively.Analysis of the ROC curves showed higher NLR and PLR were significantly associated with poorer OS and DFS (all P ＜ 0.05).Multivariate analysis showed that NLR was an independent risk factor of OS and DFS (both P ＜ 0.05).The results remained unchanged when the NLR was further analyzed by applying different cut-off values of 2.810 and 3.In subgroup analysis,NLR remained an independent factor of Barcelona Clinical Liver Cancer staging system (BCLC) 0/A/B (P ＜ 0.05 for all measurements).Conclusion An elevated preoperative NLR could be a better prognostic predictor for HCC patients in comparison with PLR,especially for BCLC 0/A/B patients.
