Objective To evaluate the surgical efficacy of end-to-end layered anastomosis for patients with esophagogastrostomy after esophagectomy.Methods Selected 35 patients who received end-to-end layered anastomosis in esophagogastrostomy after esophagectomy in people' s hospital of Meishan from January 2016 to February 2017 as end-to-end group,while 21 patients with end-to-side layered anastomosis in esophagogastrostomy after esophagectomy as end-to-side group.The anastomosis time,anastomosis tension,oppression degree,fistula incidence,acid reflux incidence,belching incidence and obstruction incidence between two groups were compared.Results The average anastomosis time was (25.17 ± 5.15)minutes in end-to-end group,and (26.10 ± 5.30)minutes in end-to-side group,the difference was not significant (P ＞ 0.05).The anastomosis tension of end-to-end group,without oppression,was mostly smaller than that of end-to-side group.There were no case of anastomotic fistula in end-to-end group and 2 cases(14.29％) of anastomotic fistula in end-to-side group,the difference was not significant (P ＞ 0.05).There were no case of obstruction in end-to-end group and 4 cases (19.05％) of obstruction in end-to-side group,the difference was significant (P =0.016).There was no significant difference in acid reflux and belching between the two groups (P ＞ 0.05) in perioperative period and 6 months after surgery.There was no delayed anastomotic fistula and anastomotic stenosis needing expansion in 6 months after surgery.Conclusion Without causing more adverse reactions,end-to-end layered anastomosis in esophagogastrostomy after esophagectomy can avoid the incision that may affect the blood supply of esophagus and stomach,and avoid the pressure from esophagus and stomach.

OBJECTIVETo investigate the occupational stressors and modifiers of pediatricians and nurses in order to find the measurements for control of the job stress.

METHODS427 pediatricians and nurses working in five hospitals of a city served as subjects. Of them, the staff in section of pharmacy and toll offices in each hospital mentioned above served as control group. The General Job Stress Questionnaire was used to investigate the job stress by self-assessment.

RESULTSThe scores of job demand, job risk, drug using, daily job stress, positive feelings, patient A behavior, physical environment and feeling balance in pediatricians and nurses were higher than those of control group, but the scores of job-person conflict, environmental control, technology utility, mental health, responsibility on things were lower than those of control group (P<0.05). The points of job future, job locus of control, self-esteem, job satisfaction, job load variance, depression in nurses were higher than those of pediatricians, and non-work activities, job risk and daily life stress were lower than those of doctors (P<0.05). The main affecting factors on job strain of pediatric staff included job monotony, higher job demand, more non-work job, lower job control, more job risk, job future ambiguous, poorer social support, lower job locus control and lower self-esteem.

CONCLUSIONThe stress degree of pediatric staff is higher than that of controls. The pediatricians have more job stress than that of nurses. The main stressors of pediatric staff are job monotony, higher job demand, more non-worker activity, lower job control, higher job risk and ambiguous job future. The main modifiers are good social support, external job locus of control and higher self-esteem.

OBJECTIVETo investigate the effect of potassium iodide on the expression of nuclear factor-kappaB and fibronectin.

METHODSThe experiment was performed with 72 SD rats weighing about 180-220 g. The animals were randomly assigned into nine groups. Group A, B, C (n=8) served as control and were fed with distilled water for 1 month, 2 month, 3 month respectively. Group D, E, F (n=8) served as lead exposed and were fed with water with 0.5% lead acetate for 1 month, 2 month, 3 month respectively. Group G, H, I (n=8) served as potassium iodide and lead exposed and were treated with 0.5% lead acetate simultaneously taking potassium iodide 3 mg/100 g weight by intragastric administration for 1 month, 2 month, 3 month respectively. Animals of different groups were sacrificed at the end of the treatment. Ultrastructure of kidney was observed by electron microscopy; Expression of NF-kappaB and FN protein and mRNA in kidney were measured respectively by immunohistochemistry and RT-PCR.

RESULTSElectron microscopic examination revealed potassium iodide could restrain the denaturalization in epithelial cells and mitochondrial cristae. The expressions of NF-kappaB protein (0.2315 +/- 0.0624, 0.3213 +/- 0.0740, 0.4729 +/- 0.0839) and mRNA (0.4370 +/- 0.0841, 0.5465 +/- 0.0503, 0.6443 +/- 0.0538) in all the lead exposed groups continuously increased compared with correspondent control groups; Group I was decreased obviously compared with group F. The expressions of FN protein (0.4243 +/- 0.0595, 0.4917 +/- 0.0891) and mRNA (0.8650 +/- 0.0880, 0.8714 +/- 0.0980) in group E and F increased compared with group B and C, but the expressions of FN protein in group I significantly decreased compared with group F; The expressions of FN mRNA in Group H and I significantly decreased compared with group E and F.

CONCLUSIONThe potassium iodide can ameliorate renal ultrastructure and degrade expression of nuclear factor-kappaB and fibronectin induced by lead.

PURPOSE: This study aims to analyze the clinical-pathological characteristics of multifocal and multicentric breast cancer (MMBC) in Chinese women. METHODS: Sixty-seven cases with MMBC were randomly collected and reviewed at seven hospitals in representative districts of China during 1999 to 2008. RESULTS: The incidence of MMBC in breast cancer in China was 1.75%. Compared to those with unifocal breast cancer, women with MMBC were more likely to have larger tumor size, lymph node metastasis (59.70% vs. 45.62%) and stage III to IV (46.26% vs. 21.10%). The peak age at onset of MMBC was 40 to 49 years old and has been gradually increasing during 1999 to 2008. Most of the MMBC women were treated with surgery and adjuvant therapy. CONCLUSION: In China, the incidence of MMBC in breast cancer is significantly lower than that in Western countries. Compared to unifocal breast cancer, MMBC is biologically more aggressive. Most MMBC women underwent mastectomy, instead of breast conservation surgery.

Improving the reproducibility of biomedical research results remains a major challenge. Transparent and accurate reporting of progress can help readers evaluate the reliability of research results and further explore an experiment by repeating or building upon its findings. The ARRIVE 2.0 guidelines, released in 2019 by the UK National Centre for the Replacement, Refinement, and Reduction of Animals in Research (NC3Rs), provide a checklist applicable to any in vivo animal research report. These guidelines aim to improve the standardization of experimental design, implementation, and reporting, as well as the reliability, repeatability, and clinical translatability of animal experimental results. The use of the ARRIVE 2.0 guidelines not only enriches the details of animal experimental research reports, ensuring that information on animal experimental results is fully evaluated and utilized, but also enables readers to understand the content expressed by the author accurately and clearly, promoting the transparency and integrity of the fundamental research review process. At present, the ARRIVE 2.0 guidelines have been widely adopted by international biomedical journals. This article is the second part of the Chinese translation of the complete interpretation of the ARRIVE 2.0 guidelines published in PLoS Biology in 2020 (original text can be found at https://arriveguidelines.org) and based on the best practices for following the ARRIVE 2.0 guidelines in international journals. This part includes Items 4-7 of "ARRIVE Essential 10" in the ARRIVE 2.0 guidelines: "Randomization", "Blinding", "Outcome Measurement", and "Statistical Methods". Our Chinese translated version aims to promote the full understanding and use of the ARRIVE 2.0 guidelines by domestic researchers, enhancing the standardization of experimental animal research and reporting, and promoting the high-quality development of experimental animal technology and comparative medicine research in China.
