ABSTRACT
Objective To observe the relation of phase angle (PA) measured by bioelectrical impedance method with nutritional status of patients with primary liver cancer, and to explore its influence on clinical outcomes. Methods We collected 120 inpatients with primary liver cancer for nutritional risk screening, patient-generated subjective nutrition assessment(PG-SGA), anthropometry, biochemical examination and body composition analysis. According to the phase angle, the patients were divided into low PA group and normal PA group. The correlation between PA and nutrition-related indicators was analyzed. The survival and complications of the two groups were compared after 1-year follow-up. Results There were 56.7% (68/120) of primary liver cancer patients with lower PA. TP, ALB, CHE, HB, AMC, GS, BCM, FFM and ASMI in low PA group were lower while ECW/TBW was higher than those in normal PA group (all P < 0.05). The correlation analysis showed that PA was negatively correlated with ECW/TBW (P < 0.05), but positively correlated with TP, ALB, CHE, HB, AMC, GS, BCM, FFM and ASMI (all P < 0.05). Low PA was significantly associated with nutritional risk, deterioration of liver function, progress of liver cancer staging and severe malnutrition (all P < 0.05). During the follow-up period, the mortality of the low PA group was higher than that of the normal PA group (P < 0.05). The risk of death in the low PA group increased by 2.738 times (OR=3.738, 95%CI: 1.465-9.535). Conclusion Phase angle is an economic and effective index to reflect the nutritional status of patients with primary liver cancer, and closely related to the risk of death. Phase angle measurement is helpful for assessing nutritional status and predicting clinical outcome of patients with primary liver cancer.
ABSTRACT
Background:Malnutrition is common in patients with cancer, whichadversely affectsthesurvival and quality of life ofcancer patients.However, there is no national data on the prevalence of malnutrition inChinese cancer patients. Thisstudy aims to evaluate the prevalenceof malnutrition and quality of life(QOL)ofChinese patients with localregional, recurrentor metastatic cancer,to address the prognostic value of nutritional status and QOLon the survival of cancer patients in China and to validate the patient-generated subjective global assessment (PG-SGA) questionnaire in Chinese cancer patients.Methods:Thisisanobservational,multi-centered,and hospital-based prospective cohort study.We aimed to recruit 50,000 cancer patients (age 18and above)overan 8-year period.Data collection will occur within 48hrafter patientsare admitted to hospital, 30-days after hospital admission, and the follow-up will be conducted1-8years after enrolment. The primary outcomeisoverall survival, and secondaryoutcomes arelength of hospital stay and hospital costs. Factors measured are demographic characteristics, tumor characteristics, anthropometry measurements,hematological measurement, body composition, PG-SGAscores,Karnofsky performance status scores,and QLQ C30 scores. This protocol wasapproved by local ethical committees of all the participant hospitals.Conclusions: This multi-centered, large-scale, long-time follow-up prospective study will help diagnose malnutrition in cancer patients in China, and identify the related risk factors associated with the negative outcomes. The anticipated results will highlight the need for a truly scientific appraisal of nutrition therapy, and help to improve outcomes among cancer patients in China.Trial Registration: The trial has been registered with the Chinese Clinical Trial Registry, ChiCTR1800020329.

ABSTRACT
Sarcopenia is the main constituent of malnutrition and is a frequent complication of chronic liver diseases, which affects up to 70% of patients with advanced liver diseases. It has been associated with adverse clinical outcomes and prognosis, including poor quality of life, development of other complications and reduction in survival rate of non-transplant patients and transplant recipients. Chronic liver disease causes alteration in glucose metabolism, lipid oxidation, ketogenesis and protein catabolism, leading to the loss of adipose and muscle tissue. In addition, inadequate nutrients intake and limited or lack of physical activity perpetuate the reduction of muscle mass. Recently, the roles and mechanisms of muscle growth-related hormones, hyperammonemia-mediated signaling pathways and gut microbiota have been recognized. In view of its impact in chronic liver disease, sarcopenia can be considered as a powerful prognostic factor and a useful additional tool in the global assessment of patients with advanced liver disease. Rational nutritional intervention, appropriate physical exercise, effective ammonia lowering strategies, hormone supplements and targeted molecular therapy (use of myostatin blockers), and liver transplantation, may improve sarcopenia, but still needs more studies for validation.
ABSTRACT
Objective@#To study the nutritional status and energy metabolic characteristics of patients with nonalcoholic fatty liver disease (NAFLD), and to provide evidence for clinical evaluation and intervention.@*Methods@#A total of 359 NAFLD patients diagnosed on ultrasound from June 2015 to March 2017 were selected as study subjects and divided into mild, moderate to severe fatty liver disease group and 50 healthy subjects as control group. The changes of ICW, ECW, body fat, skeletal muscle, protein and visceral fat area (VFA) of patients and controls were analyzed by using body composition analyzer. The energy metabolism index was measured by the oxidation rate of resting energy expenditure(REE), respiratory quotient (RQ), and the oxidation rates of the three nutrients (CHO %, FAT %, and PRO %). According to different types of data, non-parametric tests like Kruskal-Wallis or χ2 were used for this analysis.@*Results@#Compared with the mild fatty liver group and the control group, the moderate and severe fatty liver group the BMI, waist circumference, waist-hip ratio were significantly elevated (P-value < 0.001), and their serum alanine aminotransferase, triglyceride, total cholesterol, high-density lipoprotein, low-density lipoprotein, FBS levels were significantly increased (P value < 0.05). The Body composition analysis showed that there was no significant difference in skeletal muscle content between the three groups (P = 0.067). The ICW, ECW, protein, body fat content of moderate and severe fatty liver group were significantly higher than those of mild fatty liver group and control group (P < 0.01), but there was no significant difference between the mild fatty liver group and the control group. There was significant difference in the VFA between the three groups, while VFA in the moderate and severe fatty liver group was significantly increased. Metabolic results showed that the RQ of patients with moderate-severe fatty liver and mild fatty liver were 0.72 ± 0.08 and 0.78 ± 0.06, respectively, which were lower than those of the control group (0.80 ± 0.02), P = 0.004. Resting energy expenditure (REE) was not significantly different between moderate and severe fatty liver group and mild fatty liver group (P = 0.207), but both were significantly higher than those of the control group (P < 0.001). The percentages of CHO, FAT and PRO in moderate and severe fatty liver group were 19.49% ± 9.71%, 66.23% ± 12.54% and 14.22% ± 6.11% respectively. Compared with the control group, CHO % decreased, and FAT % increased.@*Conclusion@#NAFLD patients have different extent of nutritional imbalance and energy metabolism disorders, the use of Body Composition analyzer and metabolic cart can comprehensively assess and monitor NAFLD patient’s nutrition and energy metabolism status, to provide a basis for clinical intervention.
ABSTRACT
Objective To evaluate the accuracy of prediction equations in calculating energy expenditure in elderly patients with type 2 diabetes mellitus (T2DM).Methods In 75 elderly T2DM patients hospitalized in our hospital between August 2014 and August 2015,the resting energy expenditure (REE)measured with indirect calorimetry was compared with those calculated with six different prediction equations.Statistical analysis was performed with paired t-test,the percentage of individual coincidence,and BlandAltman method.Results The measured REE of the patients was (1 513.2 ± 240.6) kcal/d.There were statistically significant differences between the measured REE and the values predicted with Harris-Benedict,Owen,Mifflin,and Liu equations (all P ＜ 0.05),while no statistically significant differences were observed between the measured REE and the values predicted with FAO/WHO/UNU and Schofield equations (both P ＞0.05).FAO/WHO/UNU equation showed the smallest average difference from the measured value (-18.9 kcal/d),but the 95％ consistency limit (-363.3 kcal/d,325.5 kcal/d) was still beyond the acceptable clinical range.Conclusion The accuracy of prediction equations in estimating REE in elderly patients with T2DM may be dissatisfactory.
ABSTRACT
Objective To know the nursing students' willingness engaging in geriatric nursing and analyze affecting factors so as to provide references for nurturing professionals for caring for the aged.Methods 231 nursing students were surveyed.The questionnaire included general information,life experience with the elderly,willingness engaging in geriatric nursing,attitude towards the elderly and cognition of aging.The investigation results underwent analysis.Results Single factor analysis showed that whether ever living with the elderly (x2=6.027),time living with the elderly and relationship with the elderly (x2=4.928) influeced the nursing students' willingness engaging in geriatric nursing.Multiple correspondence analysis indicated that nursing students living with elderly more than one year and having good relationship with the elderly had positive willingness.Conclusions Geriatric nursing curriculum should be optimized and more opportunities should be created for nursing students to be in touch with the elderly.At the same time,we must pay attention to occupation guide and moral education about how to respect and care for the elderly.

ABSTRACT
Objective To probe into urban residents' mental health knowledge awareness in Jingmen city. Methods By means of self-compiled questionnaires, 563 community residents were surveyed about their mental health knowledge and access to it. Results For mental health- care knowledge, community residents scored a total of (42.52±8.79), among which, (15.34±3.25) points for relevant causes,(12.23±4.89) points for corresponding symptoms, and (14.92±4.26) for health behavior. Such aspects would affect a resident's awareness of mental health knowledge as the resident's education background,marriage and chronic diseases. Radio and television (48.3%), newspapers and magazines (41.4%), hospital expert advice (39.8%), and community medical services (36.1% ) were considered the better access to mental health knowledge. Conclusions Residents had considerably inadequate knowledge of mental health. Therefore, a variety of health- care education activities should be carried out to improve residents'mental health knowledge.

ABSTRACT
Objective To study the effect of total nutrient admixture (TNA) on lipid metabolism in rats with acute hepatic failure (AHF). Methods Fifty-six male Wistar rats were randomly divided into four groups: normal diet group, nitrogen-free diet group, fat-free nutrient admixture group, and TNA group. All rats were injected with D-galac- tosamine to induce AHF model Meanwhile, 6 healthy Wistar rats were used as control group. TNA provided energy 221.75 kJ (1 kcal=4.184 kJ), nitrogen 0.365 g, nitrogen to energy ratio 1:145, amino acids 2.28 g (including branched-chain amino acid 0.70 g), glucose 7.85 g, and fat 1.25 g on a daily basis. After 10 days of the operation of Jugular vein puncture tube, blood glucose, blood lipid, liver and renal function were determined. Results The blood glucose level was significantly higher in TNA group than that in fat-free nutrient admixture group (P < 0.05). The levels of serum triglyceride and cholesterol were highest in fat-free nutrition admixture group, and triglyceride level was signif- icantly higher than that in normal diet group and nitrogen-free diet group (P <0.05). The levels of serum triglyceride and cholesterol were significantly higher in TNA group than those in normal diet group (P <0.05). The levels of ala- nine aminotransferase, alkaline phosphatase, total bilirubin and blood urea nitrogen were lower in TNA group than those in fat-free nutrient admixture group (P < 0.05). Conclusion The nutritional proportion of TNA is suitable for the metabolism disorder of hepatic failure, and therefore TNA can reasonably promote the anabolism and reverse the deteri- oration of hepatic failure in rats.

ABSTRACT
In this study, 38 experimental subjects of diabetes mellitus were given pectin 25g extra per day orally under carefully controlled dietary plan for six weeks. Another 38 cases were selected at random as control group.Pre- and posttreatrnent, blood and urine sugar and serum insulin of each subject were measured and compared. The results were: 1) the blood sugar dropped markedly as compared with that of pretreatment (p05). 2) sugar in urine decreased evidently in contrast with control group, but no difference was seen in the volume of urine between the two groups. 3) serum insulin levels dropped significantly when compared with control group (p
