Methods Bioelectrical impedance analyzer was used to measure and analyze the body compositions of 50 patients who was underwent chemotherapy from April to May 2008. Results The compositions such as intracellular and extracellular water, total body water, protein, minerals, skeletal muscle mass were insufficient in patients who had undergone chemotherapy; 30% of the patients had excess body fat, and 40% of the patients′ body fat percent was over standard. Conclusion Because of the high consumption of disease itself and the effects of chemotherapy drugs on the body, the intake of the patients who have undergone chemotherapy is insufficient and the nutritional status is poor. We should actively evaluate their nutritional status and do some effective nutritional supports to improve the nutritional status of patients with carcinoma who have undergone chemotherapy.
ObjectivesTo evaluate the quality of guidelines on nutrition in liver disease from 2017 to 2019, and to interpret these guidelines so as to provide references for clinical practice.MethodsComputer-assisted literature searches in CNKI, VIP, WanFang Data, Medline (Ovid), The Cochrane Library, PubMed and Medlive databases were performed by two reviewers for guidelines on nutrition in liver disease from January 2017 to July 2019. Two reviewers extracted data and assessed the methodological quality of the included guidelines using AGREE II, separately. Meanwhile, the intraclass correlation coefficient (ICC) was used to assess the degree of consistency.ResultsFour guidelines were included with 2 from China and 2 from Europe. Their average standardised scores in the 6 domains of scope and purpose, stakeholder involvement, rigour of development, clarity, applicability and independence were 79.17%, 71.53%, 78.13%, 85.42%, 61.98% and 43.75%, respectively. The Chinese and European guidelines had similar recommendations for energy and other nutrients, apart from differences in recommendations for protein intake. The European guidelines considered that restricting protein intake was not beneficial for patients with hepatic encephalopathy, while the Chinese guidelines argued that patients with severe hepatic encephalopathy were required to reduce or limit their protein intake.ConclusionsAll 4 guidelines are of average quality and are required to be strengthened in the ‘independence’ domain. Currently, the only consensus on nutrition therapy for liver disease and guidelines on nutrition in end-stage liver disease are available for references in China, with lower quality scores than that of the European guidelines. Therefore, the evidence-based guidelines on nutrition in liver disease should be developed by Chinese national conditions as soon as possible to provide references for clinicians, nurses and clinical nutritionists, enableing them to implement nutrition screening, evaluation, nutritional therapy and follow-up management for patrents with liver disease.
Objective To explore the correlations between nutritional markers and pressure injury (PI) in elderly patients with chronic obstructive pulmonary disease (COPD). Methods Retrospective analysis was conducted on elderly patients with COPD and PI who were admitted to the geriatric department of West China Hospital of Sichuan University or Dujiangyan People’s Hospital between January 2020 and December 2021. The blood biochemical indicators mainly including nutritional markers were collected, and their correlations with PI risk factor index Braden score and PI severity index PI stage were analyzed. Results A total of 293 patients with COPD and PI were included. Among the five Braden score groups, the differences in the levels of albumin and prealbumin were statistically significant (P<0.05), and the Braden score was positively correlated with albumin (rs=0.241, P<0.001), prealbumin (rs=0.179, P=0.002), and hemoglobin (rs=0.199, P=0.001). Among the six PI stage groups, the differences in the levels of albumin, globulin, red blood cell count, serum sodium, blood chloride and C-reactive protein were statistically significant (P<0.05), and the PI stage was negatively correlated with albumin (rs=−0.192, P=0.001), and positively correlated with serum sodium (rs=0.139, P<0.001), blood chloride (rs=0.184, P<0.001), and C-reactive protein (rs=0.177, P=0.020). Conclusion When PI risk assessment and severity assessment are performed on elderly COPD patients, it is necessary to pay more attention to nutritional markers and assess whether the patients are at risk of protein malnutrition, which will help to improve the accuracy of PI risk assessment and severity prediction, and effectively improve the efficacy of PI prevention and treatment.
Objective To compare the effectiveness of three teaching modes, namely traditional teaching, online teaching, and online and offline blended teaching, in the teaching of the clinical nutrition elective course, and to evaluate the advantages of the online and offline blended teaching mode. Methods A total of 316 students taking the clinical nutrition elective course at Sichuan University in one of the three semesters, Fall 2019-2020, Spring 2019-2020, and Fall 2020-2021, were enrolled as the study population. In the offline group, 69 students used the traditional teaching mode; in the online group, 133 students used the online teaching mode through Chaoxing Xuexitong application; in the online and offline blended teaching group, 144 students used the traditional teaching mode combined with the online teaching. The final exam results and questionnaire satisfaction of the three groups were analyzed and compared. The exam results were presented as median (lower quartile, upper quartile). Results The exam results of the online group [males: 88.0 (85.0, 93.0); females: 91.0 (86.0, 94.0)] and the online and offline blended group [males: 90.0 (83.0, 94.0); females: 91.0 (87.5, 95.0)] were significantly higher than those of the offline group [males: 83.0 (77.0, 89.0); females: 77.5 (67.0, 87.0)] (P<0.001). Compared to the offline teaching mode and online teaching mode, the female students’ satisfaction with the online and offline teaching mode was better (P<0.01). Conclusion The online and offline blended teaching mode can significantly improve students’ performance and learning motivation, and provide a basis for promoting the reform of the clinical nutrition elective course.
Objective To investigate the effectiveness and feasibil ity of modified single-stage transpedicular decompression, debridement, and posterior instrumentation in treatment of thoracic tuberculosis. Methods Between January 2005 and December 2009, 22 cases of thoracic tuberculosis were treated with modified single-stage transpedicular decompression, debridement, and posterior instrumentation. There were 12 males and 10 females with an average age of 39.4 years (range, 22-52 years). The mean disease duration was 1.2 years (range, 3 months to 10 years). The involved vertebral bodies were T5-12, including 2 segments in 17 cases and 3 segments in 5 cases. The kyphosis Cobb angle was (31.2 ± 14.5)° before operation. According to Frankel score system for neurological deficits, 2 cases were classified as grade A, 1 case as grade B, 8 cases as grade C, 5 cases as grade D, 1 case as grade E, and 5 cases had no neurological deficits before operation. Results All incisions healed by first intention. All patients were followed up 22.2 months on average (range, 12-65 months). Pain in low back was rel ieved in varying degrees 2 weeks after operation. Fusion was achieved in the bone implant area at 3 months after operation. According to Frankel score system, 1 case was rated as grade B, 2 cases as grade C, 4 cases as grade D, 7 cases as grade E, and 8 cases had no neurological deficits at last follow-up. The kyphosis Cobb angle was (16.2 ± 3.6)°, showing significant difference when compared with the value before operation (t=5.952, P=0.001). No loosening, emersion, breakage of internal fixation or pneumothorax occurred 1 year after operation. Conclusion Single-stage transpedicular decompression and posterior instrumentation is an effective and safe method in treatment of thoracic tuberculosis.

Methods According to inclusive and exclusive criteria, 66 malignant tumor patients undergoing chemotherapy from March 2010 to November 2010 were randomized into study group and control group with 33 patients in each group. The patients in the study group were given marine collagen peptide whey protein while those in the control group were given whey protein for 21 days. Liver and kidney function, nutritional status and immune function were observed before and after intervention. Results Liver, kidney function and blood lipids of all the patients were within normal range, and were not significantly different between the two groups before and after intervention (P＞0.05). After intervention, body mass index (BMI), arm circumference, arm muscle circumference, total protein, albumin, globulin, prealbumin (PA), transferring protein of the study group were significantly increased (P＜0.05), but hemoglobin and triceps skinfold thickness had no significant changes (P＞0.05). There was no significant difference of the above parameters in the control group before and after intervention (P＞0.05). The magnitude of change of PA and BMI before and after intervention were higher in the study group than those in the control group (P＜0.05), while the magnitude of change of other parameters before and after intervention showed no significant difference between the two groups (P＞0.05). The immune function showed no significant change in both groups before and after intervention (P＞0.05), and it was also not significantly different between the two groups. Conclusion As part of dietary nitrogen sources, marine peptide can significantly improve nutritional status, including visceral protein and anthropometry in malignant tumor patients undergoing chemotherapy, but it has no significant effect on immune function, which should be further studied in detail.
Objective To explore the effects of heat-inactivated Lactobacillus gasseri TMC0356 on liver lipid metabolism in rats with metabolic syndrome (MS) and its possible mechanism. Methods Sixty male Sprague-Dawley rats were selected. Rats were randomly divided into 5 groups, including control group, MS model group and three TMC0356 test groups (low-, medium- and high-dose groups). The rats in each group were fed with different diets for 7 days, and the liver was dissected and removed after 15 weeks. The mRNA and protein expression levels of peroxisome hyperbioactive receptor-α (PPAR-α), sterol regulatory element binding protein-1c (REBP-1c), fatty acid synthase (FAS) and carnitine lipoacyltransferase-1 (CPT-1) genes in liver were detected. Results There was no significant difference in the mRNA expression of PPAR-α, SREBP-1c or CPT-1 among the five groups (P>0.05). The mRNA expression of FAS in low-dose TMC0356 test group was lower than that in MS model group (P=0.011), medium-dose TMC0356 test group (P=0.042) and high-dose TMC0356 test group (P=0.009). There was no significant difference in the expression of FAS mRNA between other groups (P>0.05). There was no significant difference in the protein expression of PPAR-α, SREBP-1c or FAS among the five groups (P>0.05). The protein expression of CPT-1 in low-dose TMC0356 test group was higher than that in control group (P=0.033) and high-dose TMC0356 test group (P=0.043). There was no significant difference in the protein expression of CPT-1 between the other groups (P>0.05). Conclusion Heat-inactivated Lactobacillus gasseri TMC0356 may improve the symptoms of metabolic disorder in rats by suppressing appetite, improving insulin resistance, and downregulating the expression of key fat metabolism genes such as FAS and SREBP-1c.
During the medical rescue of Wenchuan earthquake, on the condition of ensuring the security of producing environment and food, following the four concepts including standard production, instant cooling technology, networking management and nutrition guidance, the CPU of West China Hospital stopped the production of possibly uncontrolled food, developed a reasonable plan for materials in stock, reinforced the inspection of sources of raw materials and quality of food, adjusted styles of dishes, proviced made special food for the wounded and their relatives from different districts and nationalities, new dishes for the wounded and the medical staff, so as not only to assure the nutrition for the slightly wounded, but also to provide the individualized nutrition treatment for the severely wounded. A total of 70 077 person-times for the wounded from the disaster area (36 330 person-times for the wounded and 33 747 person-times for their family members), and 36 273 person-times for doctors and nurses have been served. Meanwhile, the food service has also been offered as regular to other patients and hospital staff, with a maximum of 18 372 person-times per day.
ObjectiveTo study the differences in body composition between maintenance hemodialysis (MHD) patients with reduced muscle mass and the ones with normal muscle mass by bioelectrical impedance analysis, and explore the influencing factors.MethodsA total of 122 patients undergoing MHD in the hemodialysis center of a general hospital between September 2018 and May 2019 were selected as the research subjects. According to the relative skeletal muscle mass index, they were divided into the muscle loss group and the normal muscle mass group. Their general conditions, post-dialysis body composition, and serum albumin were collected to analyze the differences between the two groups, and a multiple stepwise logistic regression analysis was carried out.ResultsAmong the included subjects, 53 patients had normal muscle mass and 69 patients had muscle mass loss. The post-dialysis body weight, muscle-related indexes, intracellular water, extracellular water (ECW), total body water (TBW), protein, minerals, body cell mass, bone mineral content, body mass index, arm circumference, and arm muscle circumference in the normal muscle mass group were higher than those in the muscle loss group (P<0.05); the percentage of ECW/TBW in the normal muscle mass group was lower than that in the muscle loss group (P<0.05). The multiple stepwise logistic regression analysis showed that the post-dialysis weight [odds ratio (OR)=0.679, 95% confidence interval (CI) (0.535, 0.862), P=0.001] was a protective factor from losing muscle in MHD patients, and the high ECW/TBW [OR=6.926, 95%CI (1.014, 47.280), P=0.048], low body cell mass [OR=57.707, 95%CI (6.927, 480.761), P<0.001], low bone mineral content [OR=9.743, 95%CI (1.220, 77.831, P=0.032], and arm circumference [OR=2.183, 95%CI (1.004, 4.749), P=0.049] were risk factors for muscle loss in MHD patients.ConclusionsMHD patients have a high incidence of muscle loss. It is necessary to monitor the changes of their body composition, especially those who with low post-dialysis body weight, lack of bone minerals and body cells, excessive ECW/TBW, and increased arm circumference after hemodialysis. Both nutritional interventions and exercise interventions should be performed timely and routinely to prevent the occurrence of sarcopenia.
