Sarcopenia is a series of syndromes featured by the steady and involuntary loss of skeletal muscle mass and function with aging.It can lower the quality of life and increase the risk of disability and mortality.Deficiency in some nutrients such as amino acids and proteins and accordingly the decreased in the synthesis of muscle protein and changes in muscle tissues may contribute to the development of sarcopenia.Therefore,nutritional interventions may play a role in the prevention and treatment of sarcopenia.

Objective The gastrointestinal tract of neonate becomes colonized with microorganisms from environment and mother immediately after birth. Strong evidences suggested that early composition of the microflora in neonates play an important role for postnatal development of the immune system. This study was designed to investigate the effect of mode of delivery on the development of gut microflora and characteristics of the stool in breast-fed infants by molecular biology methods. Methods Sixty healthy breast-fed term infants were enrolled in the study(including vaginal delivery group and cesarean section delivery group,each group included 30 infants). Anthropometric measurements and stool study were done at 6-week,8-week,10-week,and 12-week. Fecal samples were subjected to quantitative fluorescence real-time polymerse chain reaction assays for the enumeration of lactobacili,bifidobacteria,and subtype of bifidobacteria(bifidobacterium longum and bifidobacterium breve). Results The numbers of lactobacilli and bifidobacterium longum species were less in cesarean delivery group than those in vaginal delivery group(P ＜ 0.05). Stool mean pH was lower in vaginal delivery group than that in cesarean section delivery group(P ＜ 0.05). There were no differences in stool characteristics and growth between two groups. Conclusions Cesarean section is associated with the decrease of bifidobacteria and lactobacilli in breast-fed term infants.

Objective To gather observational data on resting energy expenditure(REE)of children with newly diagnosed malignant solid tumor, and to examine factors that might be relevant to their energy expenditure change. Methods It is a retrospective study. Data from sixty-one patients with newly diagnosed malignant tumor admitted to department of pediatric surgery in Xinhua Hospital were reviewed in this study. Resting energy expenditure was measured by indirect calorimetry. Patients with benign tumor admitted during the same period were used as the control group. Results The difference of percentage of patients with normal, decreased, or increased REE between benign and malignant groups was not significant(χ2 = 0.466, P = 0.792). Patients with one or more gastrointestinal symptoms had higher percent of Pre-REE compared with patients without any gastrointestinal symptoms, but no significant difference existed(119.8±80.4 vs 91.1±27.2, Z = 0.746, P = 0.456). Different tumor types were associated with different effects on REE. There was no significant difference in REE levels between patients with decreased diet intake and those without(Z = 0.528, P = 0.598). Conclusions It is confirmed that not all patients with malignant tumor have an increased REE. Moreover, the tumor site might be an independent factor affecting patients' REE level.

Objectives To assess the clinical value of ultrasonography (US) and bioelectrical impedance analysis (BIA) in analyzing abdominal fat contents of obese children and adolescents through comparison with MRI. A correlation with other obese related metabolic parameters was conducted. Methods Ninety 7-17-y-old obese children and adolescents (60 boys and 30 girls with mean age of 9.6 ± 2.9 y and mean BMI of 24.5 ± 4.5 kg/m2) were recruited. Metabolic parameters were measured, and insulin resistance was estimated according to homeostasis model assess-ment (HOMA-IR). On the same day abdomen subcutaneous fat thickness (SFTUS) was measured by US. Body fat mass (FMBIA) and abdominal visceral fat area (VFABIA) were analyzed by bioelectrical impedance analysis (BIA). After obtaining informed consent, abdominal MRI was performed in 20 subjects. Each section of umbilicus level was analyzed by image threshold value segmentation using SigmaScan Pro 5 and abdominal subcutaneous fat area (SFAMRI) and visceral fat area (VFAMRI) were calculated. Results (1) A strong positive association was found between SFTUS and SFAMRI (P< 0.05), VFABIA and VFAMRI (P < 0.01) respectively. (2) FMBIA and SFAMRI, VFAMRI, SFTUS also showed significant correlations (P < 0.05). (3) VFAMRI showed extremely significant positive correlations with TG, Insulin,C-peptide and HOMA-IR (P < 0.01 ) ; SFAMRI was also correlated positively with them (P < 0.05). (4) SFTUS was correlated positively with UA (uric acid), Insulin, 2HIns (insulin measured at 2 hours after meal), C-peptide,2HC-peptide (C-peptide measured at 2 hours after meal) and HOMA-IR (P < 0.01). (5) VFABIA was correlated significant positively with UA, insulin, TG, 2HIns and HOMA-IR. FMBIA showed positive correlation with UA, Insulin,2HIns, C-peptide, 2HC-peptide and HOMA-IR. Conclusions abdominal subcutaneous and visceral fat of obese children and adolescents evaluated by US and BIA are correlated well with those assessed by MRI, and also correlated well with TG, insulin, C-peptide and other metabolic biochemical parameters. Our data support the value of using cost effective, simple and convenient methods such as BIA and US to evaluate the obese and related metabolic risk of children and adolescents in clinical practice.

Objective To investigate the prevalence of overweight and obesity and the nutritional status of dietary calcium intake in school-age children in Shanghai and to analyze the relationship between dietary calcium and bone mineral density (BMD).Methods A cross-sectional study was conducted in the second and third grade students of 10 primary schools in Yangpu District and Baoshan District in Shanghai. Food frequency questionnaire was used tu estimate the relative intake of dietary calcium of students in 6 primary schools in Baoshnn District. Quantitative ultrasound bone density examination was used to estimate the calcaneal BMD.The relation-ship between calcium intake and BMD was analyzed.Results The average calcium intake was 647 mg/d among ested students.BMD was not significantly different among different age groups (F=1.595,P=0.173),while Z-score was significantly different among different age groups (F=16.02,P=0.000).The total calcium intake was not correlated with BMD or Z-score.The percentage of dairy calcium intake was positively correlated with BMD (r=0.097,P=0.015)and Z-score (r=O.117,P=0.003),the percentage of non-dairy calcium intake and the non-dairy calcium intake were negatively correlated with BMD (r=-0.097,P=0.015) and Z-score(r=-0.110,P=0.006).When the total dietary calcium intake was ≥600 mg/d,BMD and Z-score significantly higherin students with high dairy calcium intake than those with low dairy calcium intake (P<0.05).When the total dietary calcium intake was <600mg/d,BMD and Z-score were higher in students with high dairy calcium in-take than in those with low dairy calcium intake,although no statistical significance was noted (P>0.05).Conclusions BMD and Z-score increase along with the increase of dairy calcium intake.Such effect becomes even more obvious when the total dietary calcium intake is ≥600 mg/d.
