Objective To observe the effects of improving tumor cell hypoxia on radiotherapy in non-small cell lung cancer(NSCLC). Methods Forty-two patients with NSCLC on stage II to stage IV were enrolled randomly, of whom 38 patients were well documented. All patients were treated with oxygenator by intravenous oxygen delivery within thirty minutes before radiotherapy to increase partial pressure of blood oxygen and improve tumor cell hypoxia. The arterial blood gas was analysed for each patients before and after oxygen infusion. All patients receive radiotherapy at a dosage of 2 Gy each time per day, five times per week. The total dosage was 60 to 70 Gy. Another 37 NSCLC patients selected randomly in control group were treated by conventional radiotherapy. The therapeutic effects were analysed statistically according to WHO categorized standard. Results The mean PO2 was (85.6?7.5) mm Hg, (103?9.7) mm Hg, and SaO2 was (89.5?6.1) %, (94.4?5.2) % before and after oxygen infusion respectively in study group. The efficacy of radiotherapy was 63.16 %(24/38), which was higher than that in control group 43.24 % (16/37) (0.05

Objective The aim of the study was to investigate the early failure of newly created arteriovenous fistula(AVF) in patients on maintenance hemodialysis and the factors responsible for the failure. Methods The clinical data were retrospectively reviewed, preoperative examination and laboratory biochemical indicators of 88 patients with newly created AVF for maintenance hemodialysis in our hospital through Hospital Management Information System and telephone follow-ups. Binary Logistic regression was used to analyze the protective factors for early failure. Results In 88 patients, early failure of the AVF was found in 15 patients. Twenty-three factors, including gender, were involved in statistical analysis. There were statistical differences between the two groups in hypertension (χ2=7.689, P=0.006) and whether they had early referral to nephrologists (χ2=5.334, P=0.021). Further regression analysis showed hypertension ( OR=0.192, 95% CI=0.0538-0.692, P=0.012) was protective factor and without early referral ( OR=3.651, 95% CI=1.068-18.302, P=0.039) was the risk factor of early failure. Conclusion This study shows that no early referral and combined hypertension is an important factor affecting the early failure, emphasizing the clinical work, for the diagnosis of patients with chronic kidney disease, early nephrological referral should be established, and blood pressure monitoring should be done to help reduce the incidence of complications.

Objective To research the effectiveness of group counseling on nursing teaching in Operating Room. Methods A total of 72 nursing students in the Operating Room in June 2011 were divided into the control group and the observation group, with 36 students in each group. The control group underwent the traditional teaching mode. The observation group was given effectiveness group counseling. The General Self-Efficacy Scale ( GSES ) , clinical practice evaluation questionnaire and examination were used to evaluate the results of teaching. Results The scores of theory and skill examination of the observation group were (89. 2 ± 5.1)and(91.4±7.2),whichweresignificantlyhigherthanthoseofthecontrolgroup(t=5.921,7.652, respectively;P<0. 05). The self-efficacy, knowledge, skill practice and total score of clinical practice of the observation group were significantly higher than those of the control group ( t=9. 641, 6. 382, 4. 332, 8. 632, respectively;P<0. 05). Conclusions Group counseling can improve the effectiveness of self-efficacy in nursing students and improve the theoretical knowledge and practical ability.

0bjective To investigate the occurrence of frequent intradialytic hypotension in hemodialysis patients and Analyzed influencing factors. Methods The 1 933 hemodialysis sections of 156 maintenance hemodialysis patients in the Huashan hospital affiliated to Fudan University in Shanghai were selected, and divided into frequent intradialytic hypotension and non- frequent intradialytic hypotension depending on whether the incidence of intradialytic hypotension is greater than 20%, and the patients' dialysis data and biochemical examination data are collected for the analysis of influencing factors. Results The incidence of frequent IDH in maintenance hemodialysis patients was 62.18%(97/156), and the pre-dialysis blood pressure of frequent IDH patients were higher than non-frequent IDH patients, frequent IDH patients: (134.02±21.01)/(73.85±10.73) mmHg(1 mmHg=0.133 kPa), non-frequent IDH patients: (124.66 ± 17.89)/(69.32 ± 10.65) mmHg, (t=-2.851,-2.558, P＜0.05), but lower in post-dialysis, frequent IDH patients:(114.91±19.21)/(68.38±11.41) mmHg, non-frequent IDH patients: (127.90± 20.58)/(74.46±11.79) mmHg, (t=3.989, 3.189, P＜0.01). Binary Logistic regression analysis showed that hemoglobin ( OR=0.354, P=0.015) and high-density lipoprotein ( OR=0.155, P=0.003) were protective factors for the occurrence of frequent IDH, and ultrafiltration volume/weight ( OR=6.021, P=0.002) and N-terminal pro-brain natriuretic peptide ( OR=2.687, P=0.020) were risk factors. Conclusions The incidence of frequent IDH in hemodialysis patients is high, and patients with high filtration rate, high N-terminal pro-brain natriuretic peptide, low hemoglobin and high density lipoprotein should be paid close attention to. It is recommended to regularly monitor patients' biochemical indicators, strengthen blood pressure monitoring for high-risk groups, and timely deal with the symptoms of low blood pressure.

Objective:To investigate the prevalence and influencing factors of mild visual impairment in type 2 diabetic patients aged ≥50 years living in Funing County, Jiangsu Province.Methods:A population-based cross-sectional study was adopted.Cluster sampling was conducted among diabetic patients aged ≥50 years registered in the Chronic Disease Information Center of Funing County Center for Disease Prevention and Control from March 7th to April 20th, 2019.General information of selected patients was collected.Visual and ocular examinations on site were performed by ophthalmologists and technicians.The International Council of Ophthalmology standard for mild visual impairment, 0.3≤best corrected visual acuity<0.8 was adopted.The influencing factors of mild visual impairment were analyzed by logistic regression.This study protocol was approved by the Ethics Committee of Affiliated Hospital of Nantong University (No.2014-071).Results:Among the included 2 067 patients, 1 909 cases completed the investigation, with a response rate of 92.4%.There were 1 146 patients with mild visual impairment in at least one eye, and the prevalence of mild visual impairment was 60.00%.Among the eyes examined, 1 832 eyes were with mild visual impairment, accounting for 47.98%.Cataract (896/1 632), refractive error (515/1 632) and diabetic retinopathy (166/1 632) were the main causes of mild visual impairment in diabetic patients, accounting for 54.90%, 31.61% and 10.19%, respectively.Aging, female gender, low educational attainment, oral hypoglycemic drugs or subcutaneous insulin injection were risk factors for mild visual impairment in both eyes.Higher educational attainment, more sunshine exposure and exercise were protective factors for mild visual impairment in both eyes.Conclusions:The prevalence of mild visual impairment is relatively high in type 2 diabetic patients.Cataract surgery, correction of refractive error may help to improve mild visual impairment.Strengthening blood glucose control, more physical exercise and outdoor activities may slow the progression of mild visual impairment and prevent it from moderate and severe visual impairment.

Objective To explore the effect of affective commitment on thriving at work among junior male Nurses. Methods In July 2017, totally 63 junior male nurses from three classⅢ hospitals in Zhejiang province were selected and investigated by Affective Commitment Scale (ACS) and Thriving at Work Scale. Results The mean scores of ACS and thriving at work were (20.29±3.83) and (42.65±5.79). Affective commitment was significantly positive correlated to thriving at work, and its two dimensions (including dynamic dimension and learning dimension) (r=0.364, 0.270, 0.350;P< 0.05). The hierarchical regression analysis showed that the organizational affective commitment can explain 45.20% of the work enthusiasm in junior male nurses. Conclusions Junior male nurses' affective commitment and thriving at work were at a low level. The affective commitment was an important influencing factor of thriving at work.

OBJECTIVETo study the efficacy and safety of thoracoscopic and laparoscopic esophagectomy for esophageal carcinoma.

METHODSBased on hospitalization data from March 2011 to March 2014, 62 cases of esophageal carcinoma treated with thoracoscopic and laparoscopic esophagectomy (minimally invasive group, with 45 male patients) and other 62 cases treated with open esophagectomy (open esophagectomy group, with 45 male patients) were analyzed in a retrospective cohort. The mean age of two groups were (62±9) years and (62±8) years, respectively. Quantitative data were analyzed using t-test, whereas qualitative variables were tested with χ2 test. There were no significant difference in age, tumor location, pathological type, tumor staging between two groups (P>0.05). Perioperative data and three-year clinic outcome were collected. The three-year survival curve were calculated with the Kaplan-Meier method and compared by the log-rank test between the two groups.

RESULTSCompared with open esophagectomy group, minimally invasive group has less amount of bleeding during operations ((231±40) ml vs. (302±37) ml, t=4.63, P=0.000), pleural drainage after operations ((490±41) ml vs. (1 090±43) ml, t=-79.59, P=0.000), and postoperative hospital stay ((16±4) days vs. (17±4) days, t=-2.61, P=0.010). Meanwhile, minimally invasive group has more operation time ((272±39) minutes vs. (242±45) minutes, t=3.97, P=0.000) and total and thoracic cavity retrieved lymph nodes (30±5 vs. 28±4, t=2.39, P=0.018; 15±4 vs. 14±3, t=2.59, P=0.011). Nineteen and 31 patients had postoperative complications and statistical significance difference was found between two groups (χ2=4.83, P=0.028). The three-year survival rate was 73.2% in minimally invasive group and 71.4% in open esophagectomy group. There was no significance difference between two groups (χ2=0.170, P>0.05).

CONCLUSIONThoracoscopic and laparoscopic esophagectomy had the advantages of amount of bleeding, postoperative hospital stay and complications, and had the same three-year survival rate with open esophagectomy.
