Objective: To investigate the consumption of vegetables and fruits and related influencing factors among residents from the National Demonstration Areas of Comprehensive Prevention and Control of Non-communicable Diseases. Methods: From November to December, 2016, a total of 4 000 residents, aged 18 or above, from ten Demonstration Areas, were selected as participants for this study by multi-stage cluster random sampling method. Information on vegetables, fruits consumption and related influencing factors was collected via questionnaire. Results: A total of 3 891 residents were involved in the final analysis. Daily consumption of vegetables and fruits accounted for 72.1% and 53.6% of the residents under study. The residents who were aware of the National Demonstration Areas activities were more willing to have adequate intake of vegetables (OR=3.017, 95%CI: 2.426-3.753) and fruits (OR=1.261, 95%CI: 1.007-1.580). Residents with higher degree of participation activities of the demonstration areas were more likely to have adequate fruits intake (high degree: OR=1.431, 95%CI: 1.210-1.694; medium degree: OR=1.573, 95%CI: 1.315- 1.882). Conclusions: The implementation of the National Demonstration Areas for Comprehensive Prevention and Control of Non-communicable Diseases has improved the adequate vegetables and fruits intake among residents. Relevant activities carried out in the Demonstration Areas appeared conducive to the healthy lifestyle of the residents.

A case of supratentorial ependymoma in a 48-year-old man. After operation and radiological treatment, metastasis to scalp and cervical lymph node occurred, without recurrence of primary focus. 11 cases of intracranial ependymoma with extracranial metastasis were reviewed. Metastasizing intracranial ependymomas are 3 times as frequent in males and originate above tentorium. The most effective transmission of metastasis of ependymoma is through the blood stream and the frequent sites of metastasis are lungs, pulmonary hilus, mediatinum, liver, scalp, vertebra, femoral bone and cervical lymph nodes. Our case is the oldest among reported cases and metastasized to relatively rare site.

BACKGROUND: Soft tissue integration (STI) around dental implant abutments is a prerequisite to prevent bacterial invasion and achieve successful dental implant rehabilitation. However, peri-implant STI is a major challenge after dental abutment placement due to alterations in the immune microenvironment upon surgical dental implant installation. METHODS: Based on known immunomodulatory effects of zinc, we herein deposited zinc/chitosan/gelatin (Zn/CS/Gel) coatings onto titanium substrates to study their effect on macrophages. First, we exposed macrophages to cell culture media containing different zinc ion (Zn2+) concentrations. Next, we explored the immunomodulatory effect of Zn/CS/Gel coatings prepared via facile electrophoretic deposition (EPD). RESULTS: We found that Zn2+ effectively altered the secretome by reducing the secretion of pro-inflammatory and enhancing pro-regenerative cytokine secretion, particularly at a Zn2+ supplementation of approximately 37.5 μM. Zn/CS/Gel coatings released Zn2+ in a concentration range which effectively stimulated pro-regenerative macrophage polarization as demonstrated by M2 macrophage polarization. Additionally, the impact of these Zn2+-exposed macrophages on gingival fibroblasts incubated in conditioned medium showed stimulated adhesion, proliferation, and collagen secretion. CONCLUSION Our promising results suggest that controlled release of Zn2+ from Zn/CS/Gel coatings could be applied to immunomodulate peri-implant STI, and to enhance dental implant survival.

To assess the effect of a NO-eluting stent on reducing neointimal thickening in a porcine coronary artery stent injury model, sodium nitroprusside (SNP), a NO donor, was incorporated into polyurethane (PU) polymer and coated onto metallic coil stents, and two types of stents with thin and thick barrier coatings were characterized. In vivo biological activity of the NO-eluting stents was assessed by measurement of coronary arterial cGMP levels in 32 pigs/64 arteries at days 1, 2, 7 and 14. Morphometric analyses were performed in 16 pigs to determine the effect of NO-eluting stents on neointimal hyperplasia 28 days following arterial injury. The SNP-coated stents released NO in a controlled manner for up to 4 weeks in the in vitro experiments and an increase in local tissue cGMP levels was demonstrated for up to 14 days. The neointimal area at 28 days was not diminished, however, by NO eluded from either stents of thin or thick barriers (control bare stent - 0.66 mm2, control PU stent - 0.68 mm2, SNP-PU thin coating stent - 0.78 mm2, SNP-PU thick coating stent - 0.85 mm2; all p=NS). In conclusion, the SNP-coated polymer stent exerted a local biological effect on the arterial wall, with sustained elevation of cGMP level. Although local delivery of NO from this device did not reduce neointimal hyperplasia in this porcine model, this polymer-coated stent might be a promising tool for administration of other agents that may modify the reparative tissue responses leading to restenosis.

Currently, the standard of clinical complete response (cCR) after neoadjuvant chemoradiotherapy (nCRT) for local advanced rectal cancer generally lacks pathological examination, the cCR judged by the current standard is still far from the real pathological complete response. After nCRT, due to the presence of tissue edema and fibrosis, MRI is highly uncertain in determining the staging of local lesions. The precision of colonoscopy biopsy is generally low because residual cancer foci exist primarily in the muscular layer, which limits the determination of cCR by colonoscopy biopsy. Local excision through the anus can resect the whole intestinal wall tissue, which is relatively accurate and close to the real state of remission of the lesion, but there are many problems, such as affecting anal function, high rate of complications, and increased difficulty of following radical surgery. Based on the present diagnosis of cCR, the authors put forward the concept of modified cCR (m-cCR) which combined with the pathological standard of transanal multipoint full-layer puncture biopsy. It is possible to improve the accuracy of cCR, and improve the safety of cCR patients who receive wait-and-watch therapy without increasing complications or affecting anal function. The exact conclusion needs to be confirmed by further studies.

OBJECTIVES: To describe the time perspective of return to work and the factors that facilitate and hinder return to work in a group of survivors of acute coronary syndrome (ACS). METHODS: Retrospective semi-structured telephone survey 2 to 3 years after hospitalization with 84 employed Dutch ACS-patients from one academic medical hospital. RESULTS: Fifty-eight percent of patients returned to work within 3 months, whereas at least 88% returned to work once within 2 years. Two years after hospitalization, 12% of ACS patients had not returned to work at all, and 24% were working, but not at pre-ACS levels. For all ACS-patients, the most mentioned categories of facilitating factors to return to work were having no complaints and not having signs or symptoms of heart disease. Physical incapacity, co-morbidity, and mental incapacity were the top 3 categories of hindering factors against returning to work. CONCLUSION: Within 2 years, 36% of the patients had not returned to work at their pre-ACS levels. Disease factors, functional capacity, environmental factors, and personal factors were listed as affecting subjects' work ability level.
