The generation and regeneration of deer antler is regulated not only by hormones, but also by nutritional factors. Nutritional factors have great influences on pedicle generation, first antler generation and antler development. Therefore, this paper summarizes recent advances in the study of the influences of nutritional factors on antler generation and regeneration, analyzes the pathways regulating antler generation and regeneration by nutritional factors, and proposes thai nutritional factors regulale antler regeneralion by direct pathway and indirect pathway.展开更多

This study is aimed to explore nutritional risk screening and its influencing factors of hospitalized patients in central urban area. It is helpful for the early detection of problems in nutritional supports, nutrition management and the implementation of intervention measures, which will contribute a lot to improving the patient＇s poor clinical outcome. A total of three tertiary medical institutions were enrolled in this study. From October 2015 to June 2016, 1202 hospitalized patients aged ≥18 years were enrolled in Nutrition Risk Screening 2002（NRS2002） for nutritional risk screening, including 8 cases who refused to participate, 5 cases of same-day surgery and 5 cases of coma. A single-factor chi-square test was performed on 312 patients with nutritional risk and 872 hospitalized patients without nutritional risk. Logistic regression analysis was performed with univariate analysis（P〈0.05）, to investigate the incidence of nutritional risk and influencing factors. The incidence of nutritional risk was 26.35% in the inpatients, 25.90% in male and 26.84% in female, respectively. The single-factor analysis showed that the age ≥60, sleeping disorder, fasting, intraoperative bleeding, the surgery in recent month, digestive diseases, metabolic diseases and endocrine system diseases had significant effects on nutritional risk（P〈0.05）. Having considered the above-mentioned factors as independent variables and nutritional risk（Y=1, N=0） as dependent variable, logistic regression analysis revealed that the age ≥60, fasting, sleeping disorders, the surgery in recent month and digestive diseases are hazardous factors for nutritional risk. Nutritional risk exists in hospitalized patients in central urban areas. Nutritional risk screening should be conducted for inpatients. Nutritional intervention programs should be formulated in consideration of those influencing factors, which enable to reduce the nutritional risk and to promote the rehabilitation of inpatients.展开更多

Thus, the present study was conducted to identify the risk factors of IPN secondary to SAP. METHODS： The clinical data of patients with SAP were retrospectively analyzed. Univariate and multivariate logistic regression analyses were sequentially performed to assess the associations between the variables and the development of IPN secondary to SAP. A receiver operating characteristic（ROC） curve was created for each of the qualified independent risk factors. RESULTS： Of the 115 eligible patients, 39（33.9%） progressed to IPN, and the overall in-hospital mortality was 11.3%（13/115）.The early enteral nutrition（EEN）（P=0.0092, OR=0.264）, maximum intra-abdominal pressure（IAP）（P=0.0398, OR=1.131）and maximum D-dimer level（P=0.0001, OR=1.006） in the first three consecutive days were independent risk factors associated with IPN secondary to SAP. The area under ROC curve（AUC） was 0.774 for the maximum D-dimer level in the first three consecutive days and the sensitivity was 90% and the specificity was 58% at a cut-off value of 933.5 μg/L; the AUC was 0.831 for the maximum IAP in the first three consecutive days and the sensitivity was 95% and specificity was 58%at a cut-off value of 13.5 mm Hg. CONCLUSIONS： The present study suggested that the maximum D-dimer level and/or maximum IAP in the first three consecutive days after admission were risk factors of IPN secondary to SAP; an EEN might be helpful to prevent the progression of IPN secondary to SAP.展开更多
