DeepCCI: a deep learning framework for identifying cell-cell interactions from single-cell RNA sequencing data.

MOTIVATION: Cell-cell interactions (CCIs) play critical roles in many biological processes such as cellular differentiation, tissue homeostasis, and immune response. With the rapid development of high throughput single-cell RNA sequencing (scRNA-seq) technologies, it is of high importance to identify CCIs from the ever-increasing scRNA-seq data. However, limited by the algorithmic constraints, current computational methods based on statistical strategies ignore some key latent information contained in scRNA-seq data with high sparsity and heterogeneity. RESULTS: Here, we developed a deep learning framework named DeepCCI to identify meaningful CCIs from scRNA-seq data. Applications of DeepCCI to a wide range of publicly available datasets from diverse technologies and platforms demonstrate its ability to predict significant CCIs accurately and effectively. Powered by the flexible and easy-to-use software, DeepCCI can provide the one-stop solution to discover meaningful intercellular interactions and build CCI networks from scRNA-seq data. AVAILABILITY AND IMPLEMENTATION: The source code of DeepCCI is available online at https://github.com/JiangBioLab/DeepCCI.

[Comparison study of the new national standard infant formula and dietary reference intakes 2023].

OBJECTIVE: To compare the relationship between the nutrient limit in new national standard Infant Formula(GB 10765-2021)(New GB)and the corresponding nutrients in Dietary Reference Intakes for China 2023(DRIs 2023), to determine the scientific and reasonable base of each nutrient in New GB, and provide supports for future revision of it. METHODS: Using a data conversion method, the adequate intake(AI) of each nutrient recommended by DRIs 2023 for infants aged 0-6 months and the nutrient limit in the New GB were input into the Excel table. Based on authoritative data on the representative weight of 0-6 month infants and the recommended energy values, the conversion was done, the ratio of the lower limit of each nutrient in New GB and the AI of corresponding nutrient, as well as the ratio of the upper limit of nutrients in New GB and their tolerable upper intake level(UL) were calculated. RESULTS: For most nutrients in New GB for infant formula, the ratio of the lower limit to their AI is close to 1. For those nutrients with a large ratio of the lower limit to AI, or with a ratio of the upper limit to UL were greater than 1, detail analysis was conducted. CONCLUSION: Based on DRIs 2023, the nutrient limit for each nutrient in New GB for infant formula was scientific and reasonable. For some nutrients with a large ratio, more studies should be done in the future to determine whether the limit in National Standard need to be adjusted.

Effects of Sn-2-palmitate-enriched formula feeding on infants' growth, stool characteristics, stool fatty acid soap contents and bone mineral content: A systematic review and meta-analysis of randomized controlled trials.

This systematic review and meta-analysis was performed to assess the effects of Sn-2-palmitate-enriched formula feeding on infants' growth, stool characteristics, stool fatty acid (FA) soap contents and bone mineral content (BMC). We searched PubMed, MEDLINE, Embase and Web of Science for randomized controlled trials published up to April 2022. Sixteen studies involving 1,931 infants were included. From each included study, weighted mean differences (WMDs) and 95% confidence intervals (CIs) for each of the above mentioned outcomes were extracted and pooled with a fixed-effects model (I2 ≤ 50%) or a random-effects model (I2 > 50%). Infants fed Sn-2-palmitate-enriched formula exhibited greater weight gains (WMD: 0.81; 95% CI: 0.23, 1.39 g/d; I2 = 0.00%), lower contents of total stool FA soaps (WMD: -3.47; 95% CI: -5.08, -1.86 mg/100 mg; I2 = 0.00%) and higher BMC (WMD: 7.08; 95% CI: 4.05, 10.10; I2 = 0.00%) than infants fed standard formula. However, no difference was observed in these outcomes between infants fed Sn-2-palmitate-enriched formula and those fed human milk. This meta-analysis demonstrated that compared with standard formula feeding, Sn-2-palmitate-enriched formula feeding could effectively promote weight gains, bone mineral accumulation and stool FA soap reduction in infants.

Effects of three medical nutrition therapies on nutritional metabolism and intestinal flora in overweight/obese with polycystic ovary syndrome (PCOS): Study protocol for a randomised controlled trial.

BACKGROUND AND OBJECTIVES: Observational studies have shown that energy restriction could be beneficial for controlling bodyweight in patients with polycystic ovary syndrome (PCOS). We aim to compare the effects of a high-protein diet (HPD), a high-protein and high-dietary fiber diet (HPHFD), and a calorie-restricted diet (CRD) on metabolic health and gut microbiota in overweight/obese PCOS patients. METHODS AND STUDY DESIGN: We will enroll a total of 90 overweight/obese PCOS patients into this eight-week open-label randomised controlled trial. Participants will be randomly assigned to three groups: CRD group (energy coefficient 20 kcal/kg.day, water ≥1500 mL, 0.8-1.2 g/kg protein, carbohydrate energize 55-60%, and fat energize 25-30%), HDP group (energy coefficient 20 kcal/kg.day, water ≥1500 mL, and 1.5-2.0 g/kg protein) and HPHFD group (based on the high protein diet with 15 g more dietary fiber supplement). The primary outcome is body weight, body fat percentage, and lean body mass. The secondary outcomes will include changes in blood lipids, inflammation, glucose tolerance, blood pressure, and gut microbiota compositions. Between-group differences in adiposity measurements at baseline will be compared using one-way analysis of variance (ANOVA) or Kruskal-Wallis test when appropriate. Within-group difference after 8-week intervention will be compared using paired t-test or Wilcoxon signed rank test. Between-group differences in adiposity measurements after 8-week diet intervention will be compared using linear mixed model and ANCOVA. The gut microbiota will be analyzed using 16S amplicon sequencing and the sequencing data will be analyzed using the standardized QIIME2 piperline.

Ameliorating Effects of Vitamin K2 on Dextran Sulfate Sodium-Induced Ulcerative Colitis in Mice.

Ulcerative colitis (UC) is a chronic recurrent inflammatory illness of the gastrointestinal system. The purpose of this study was to explore the alleviating effect of vitamin K2 (VK2) on UC, as well as its mechanism. C57BL/6J mice were given 3% DSS for seven days to establish UC, and they then received VK2 (15, 30, or 60 mg/kg·bw) and 5-aminosalicylic acid (100 mg/kg·bw) for two weeks. We recorded the clinical signs, body weights, colon lengths, and histological changes during the experiment. We detected the inflammatory factor expressions using enzyme-linked immunosorbent assay (ELISA) kits, and we detected the tight junction proteins using Western blotting. We analyzed the intestinal microbiota alterations and short-chain fatty acids (SCFAs) using 16S rRNA sequencing and targeted metabolomics. According to the results, VK2 restored the colon lengths, improved the colonic histopathology, reduced the levels of proinflammatory cytokines (such as IL-1ß, TNF-α, and IL-6), and boosted the level of the immunosuppressive cytokine IL-10 in the colon tissues of the colitis mice. Moreover, VK2 promoted the expression of mucin and tight junction proteins (such as occludin and zonula occludens-1) in order to preserve the intestinal mucosal barrier function and prevent UC in mice. Additionally, after the VK2 intervention, the SCFAs and SCFA-producing genera, such as Eubacterium_ruminantium_group and Faecalibaculum, were elevated in the colon. In conclusion, VK2 alleviated the DSS-induced colitis in the mice, perhaps by boosting the dominant intestinal microflora, such as Faecalibaculum, by reducing intestinal microflora dysbiosis, and by modulating the expression of SCFAs, inflammatory factors, and intestinal barrier proteins.

Poor diet quality evaluated with the China Healthy Diet Index in Chinese tuberculosis patients.

OBJECTIVE: The purpose of this study was to compare and evaluate the diet quality of tuberculosis patients and healthy adults by using the China Healthy Diet Index (CHDI) and to provide guidance for the diet of tuberculosis patients in the future. METHODS: A case-control study of 1241 patients and 1241 healthy individuals matchedfor sex and age. The CHDI was used to score the overall diet quality of patients in the casegroup and the control group. RESULTS: The CHDI score of tuberculosis patients was 61.61 and that of healthy controls was 63.97. After adjustment for confounders, participants with >80 on CHDI were 73.5% less likely to develop tuberculosis than participants with <51 (OR: 0.265, 95% CI: 0.086, 0.813, p < 0.05). In the original model, the CHDI scores in the highest range were inversely associated with tuberculosis risk compared with the lowest range (OR: 0.687, 95% CI: 0.420,1.122, p < 0.001). After adjusting for confounders, the CHDI score was significantly associated with a reduced risk of tuberculosis (OR: 0.265, 95% CI: 0.086, 0.813, p < 0.001). After adjusting for confounders, a high-quality diet was positively correlated with anti-tuberculosis treatment outcomes (OR:0.957, 95% CI: 0.918,0.998, p = 0.039). CONCLUSION: Compared with healthy adults, tuberculosis patients have poor diet quality with unreasonable diet structure. The insufficient intake of whole grains, vegetables, beans, aquatic products, meat and eggs and the excessive intake of pure energy food and solid fat suggests that the dietary structure of tuberculosis patients was unreasonable. This study provides an idea of the diet structure of tuberculosis patients.

[Association between the awareness of Nutrition Facts Panel and prepackaged food purchase behavior among residents].

Objective: To explore the association between the cognition of Nutrition Facts Panel and prepackaged food purchase behavior among residents in six provinces in China. Methods: Using a multi-stage sampling method, 3 002 adults aged 18-70 were selected from the western region (Sichuan), eastern region (Guangdong, Jiangsu, Beijing), central region (Henan), and northeastern region (Heilongjiang) of China from July 2020 to March 2021. Socio-demographic characteristics of participants and their cognition of Nutrition Facts Panel and prepackaged food purchase behavior were collected through questionnaire. A multivariate binary logistic regression model was used to analyze the association between cognition of Nutrition Facts Panel and prepackaged food purchase behavior. Results: The age of 3 002 subjects was (42.3±13.4) years, among which 63.8% (1 914) were female, 66.7% knew the Nutrition Facts Panel, 49.8% would read it when purchasing, 30.7% could understand it, and 56.6% (1 699) bought prepackaged food more than once a week. The results of multivariate analysis showed that after adjusting for relevant confounding factors, compared with the participants knowing but not reading the Nutrition Facts Panel, the group knowing and reading was more likely to buy 11 types of prepackaged food at least once a week (all P<0.05). Compared with the participants reading but not understanding the Nutrition Facts Panel, the group reading and understanding was less likely to buy 11 types of prepackaged food at least once a week (all P<0.05). Conclusion: There was a correlation between cognition of Nutrition Facts Panel and prepackaged food purchase behavior among residents.

Binary Solvent Systems for Piezoelectric Printing Crack-Free PAM/ZrOx Hybrid Thin Films through Nanostructure Modulation.

Polymer/oxide hybrid thin films, which have excellent electrical and mechanical performance, can be effectively fabricated through the sol-gel process, showing great potential in the future printed electronics. However, gelation of polymer/oxide ink systems can easily occur during a thermal process in which case capillary stress can lead to the crack of printed films due to the long period of stress accumulation. To solve this problem, the effect of different solvent systems on formed PAM/ZrOx hybrid films, which were printed by piezoelectric printing, was studied in this paper, including single solvent systems of glycol and binary solvent systems of glycol and water. The result showed that the microstructure characteristics and mechanical properties of hybrid nanostructures formed in different solvent systems varied significantly, and crack behavior can be regulated by simply adjusting the water volume ratio of the solvent system. The crack formation was significantly inhibited when the water volume ratio reached 25%.

NMR spectroscopy based metabolomics confirms the aggravation of metabolic disorder in metabolic syndrome combined with hyperuricemia.

BACKGROUND AND AIMS: Hyperuricemia (HUA) were associated with Metabolic syndrome (MetS) and its components. However, the molecular mechanism of uric acid in the development of MetS was not well elucidated. The aim of this study was developing a systemic metabolic profile by using metabolomics approach to explore the molecular mechanism of uric acid in the development of MetS. METHODS AND RESULTS: Anthropometric, clinical biochemical data, and serum samples were collected from patients with MetS, MetS combined with HUA (MetS & HUA) and healthy controls. 1H nuclear magnetic resonance (NMR) spectroscopy was used to detect endogenous small molecule metabolites of serum samples, then multivariate statistical analysis was applied to distinguish samples of different groups. In addition, pathway analysis was performed to contribute to understanding the metabolic change. By serum metabolic profiling, a total of 20 identified metabolites including lipids, amino acids, and organic acids were significantly altered in MetS and MetS & HUA patients. MetS & HUA patients presented a more severe disorder in both identified metabolites and BMI and biochemical indexes. According to pathway analysis, there were 3 and 5 metabolic pathways remarkably perturbed in MetS and MetS & HUA group respectively. CONCLUSION: Taken together, we identified disordered metabolites and related pathways for both MetS and MetS & HUA patients, and found a more severe metabolic disorder in MetS patients who has a higher serum uric acid. Our study provides biochemical insights into the metabolic alteration for the progress of MetS.

Total and Sn-2 Fatty Acid Profile in Human Colostrum and Mature Breast Milk of Women Living in Inland and Coastal Areas of China.

INTRODUCTION: Although lipid is the major energy source and exerts beneficial effects on infant growth, research on the composition of fatty acid (FA) at the sn-2 position of human milk (HM) in China and abroad is limited. OBJECTIVES: This study aimed to investigate the FA positional distribution in colostrum and mature HM of women living in the inland and coastal areas of China and explore the potential influences of geographical region and lactation stage on the FA profile of Chinese women. METHODS: Colostrum milk (n = 61) and mature milk (n = 56) samples were obtained longitudinally from healthy lactating women in Guangzhou and Chengdu, China. Gas chromatography was used to determine the total and sn-2 FA composition. RESULTS: Significant differences were observed in the FA profile of HM between different regions and lactation stages, with differences in polyunsaturated FA levels being the most pronounced. Nearly 70% of sn-2 FAs were saturated FAs, of which C16:0 accounted for approximately 75%. C8:0, C10:0, C18:0, C20:0, C22:0, and all of the unsaturated FAs were mainly located at the sn-1 and sn-3 positions, while C14:0, C15:0, and C16:0 were mainly at the sn-2 position. The proportion of C12:0 and C17:0 at sn-2 was approximately equivalent to that at the sn-1, 3 positions. CONCLUSIONS: The results indicate the variability in the FA profile of HM between regions and lactation stages. The contents of polyunsaturated FAs and sn-2 FAs, especially palmitic acid, should be paid more attention when optimizing infant formula.

Effects of fish oil supplementation on glucose control and lipid levels among patients with type 2 diabetes mellitus: a Meta-analysis of randomized controlled trials.

BACKGROUND: Previous studies have yielded inconsistent findings on the role of fish oil in type 2 diabetes mellitus (T2DM). We systematically summarized the available evidence from randomized controlled trials (RCT) and aimed to investigate the effects of fish oil supplementation on glucose control and lipid levels among patients with T2DM. METHODS: A comprehensive literature search was performed in electronic databases (PubMed, ProQuest, Cochrane Library, CNKI, VIP, and Wanfang) to identify all relevant RCTs which were published up to May 31st, 2019. We used Modified Jadad Score system to evaluate the quality of each included RCT. The pooled effects were estimated using random-effects model and presented as standardized mean differences with 95% confidence intervals. RESULTS: A total of 12 RCTs were included in this meta-analysis. There was no significant difference in glucose control outcomes comparing fish oil supplementation to placebo. The effect size of fasting plasma glucose (FPG) was 0.13 (95% CI: - 0.03 to 0.28, p > 0.05). No marked change was observed in fasting insulin (FINS), glycosylated hemoglobin (HbA1c), and HOMA of insulin resistance (HOMA-IR) levels. Fish oil supplementation was associated with a decrease of triglyceride (TG) level by - 0.40 (95%CI: - 0.53 to - 0.28, p < 0.05), and an increase of high density lipoprotein (HDL) cholesterol level by 0.21 (95%CI: 0.05 to 0.37, p < 0.05). In subgroup analysis, HDL cholesterol level was higher among Asian and low-dose(< 2 g/d n-3 PUFA) subgroups compared to their counterparts (p < 0.05). TG level was lower in mid and long duration groups, along with an inconspicuous difference in short duration group. CONCLUSIONS: This meta-analysis shows that among patients with T2DM, fish oil supplementation leads to a favorable blood lipids profile but does not improve glucose control.

Primary hyperoxaluria diagnosed after kidney transplantation failure: lesson from 3 case reports and literature review.

BACKGROUND: Primary hyperoxaluria (PH) is a rare inborn disorder of the metabolism of glyoxylate, which causes the hallmark production oxalate and forms insoluble calcium oxalate crystals that accumulate in the kidney and other organs. Since the manifestation of PH varies from recurrent nephrolithiasis, nephrocalcinosis, and end-stage renal disease with age at onset of symptoms ranging from infancy to the sixth decade, the disease remains undiagnosed until after kidney transplantation in some cases. CASE PRESENTATION: Herein, we report 3 cases of PH diagnosed after kidney transplantation failure, providing the comprehensive clinical course, the ultrasonic image of renal graft and pathologic image of the biopsy, highlighting the relevance of biopsy findings and the results of molecular genetic testing. We also focus on the treatment and the unfavorable outcome of the patients. Meanwhile, we review the literature and show the additional 10 reported cases of PH diagnosed after kidney transplantation. Additionally, we discuss the progressive molecular understanding of the mechanisms involved in PH and molecular therapy. CONCLUSIONS: Overall, the necessity of preoperative screening of PH in all patients even with a minor history of nephrolithiasis and the importance of proper treatment are the lessons we learn from the 3 cases, which prompt us to avoid tragedies.

Advances and gaps in recommendations for adequate water intake in China.

Water is essential for life survival and development. It plays a pivotal role in metabolic function, modulates normal osmotic pressure, maintains the electrolyte balance, and regulates body temperature. Adequate water intake is necessary for optimal hydration-both excessive and insufficient water consumption can have adverse effects on health. Water requirements among people vary based on various factors such as gender, age, physical activity, dietary factors, ambient temperature, and renal concentrating capacity. In recent years, water intake guidelines have been developed in some countries and by some organisations. Even in China, it is important to develop such guidelines considering specific dietary habits, height of people, and environmental factors. In 2013, guidelines for adequate water intake were developed in China, but the scope was somewhat limited; there are still specific challenges in formulating such recommendations. Future water-related studies should focus on surveying water intake among infants and toddlers, older adults, and pregnant and lactating women. Moreover, additional studies should be conducted to elucidate water intake among adults and adolescents in different regions and seasons, and the association between water intake and related diseases should also be investigated. It is imperative to transform the results of scientific research into action plans for water-related health education so as to inform and evaluate pertinent public health programmes.

Effect of palm oil consumption on plasma lipid concentrations related to cardiovascular disease: a systematic review and meta-analysis.

BACKGROUND AND OBJECTIVES: The precise association between palm oil consumption and lipid-related cardiovascular disease risk remains unclear. A systematic review was thus performed to assess whether palm oil consumption has a negative effect on plasma lipid-related cardiovascular disease marker levels. METHODS AND STUDY DESIGN: In June 2018, the electronic bibliographic databases PubMed, EMBASE (Ovid), the Cochrane Library (Ovid) and the Chinese National Knowledge Infrastructure were searched and a total of 11 eligible dietary intervention articles involving 961 volunteers were selected. Both random and fixed effect models were used to calculate pooled weighted mean differences (WMD). RESULTS: A total of 11 articles involving 547 participants met the inclusion criteria. The pooled analysis revealed that palm oil increased the concentration of high-density lipoprotein cholesterol (WMD: 0.15 mmol/L; p<0.00001). Palm oil consumption had no significant effects on blood total cholesterol (WMD: -0.01 mmol/L; p=0.82) and LDL-c (WMD: -0.05mmol/L; p=0.10) and triglyceride concentrations (WMD: 0.00 mmol/L; p=0.96), relative to the effects of unsaturated fatty acid consumption. Subgroup analyses revealed that palm oil has a beneficial effect on High-density lipoprotein cholesterol levels when more than 30% of total dietary energy was constituted by fat. CONCLUSIONS: This review revealed that palm oil does not induce increases in cardiovascular disease risk risk-related biomarkers relative to unsaturated fatty acids. Furthermore, larger-scale samples of human dietary intervention trials are required to increase the accuracy of meta-analyses.

Composition requirements of follow-up formula for 6-12-month-old infants: recommendations of a Chinese expert group.

BACKGROUND AND OBJECTIVES: The Chinese national standard of formula for 6-12-month-old infants (GB 10767- 2010) requires review and revision because it does not correspond to current scientific knowledge and data. The aim of this paper was to summarize the formula composition recommended for 6-12-month-old infants by a Chinese expert group. METHODS AND STUDY DESIGN: Formula composition recommendations for 6-12-month-old infants were devised by a Chinese expert group based on a detailed systematic review, which included nutrient intake, nutrient content of Chinese women's breast milk, and the latest adequate intake and tolerable upper intake levels, also referencing the Codex Alimentarius recommendations and those of other countries and considering the practice in products on the market. RESULTS: Compared with current standards, it was recommended that most compositional requirements be modified, including decreasing the maximum energy density from 85 to 75 kcal/100 mL, decreasing the protein content in milk-based formula from 2.9-5.0 g/100 kcal to 1.8-3.5 g/100 kcal, increasing the minimum content of lipids from 2.9 g/100 kcal to 3.5 g/100 kcal, providing the maximum amount of vitamins and minerals (including vitamin E, vitamin K, thiamin, riboflavin, vitamin B-6, vitamin B-12, niacin, folic acid, pantothenic acid, vitamin C, biotin, magnesium, calcium, phosphorus, and iodine), and changing the content of optional components such as taurine, docosahexaenoic acid, and arachidonic acid. CONCLUSIONS: These nutrient standard modifications based on recent evidence are expected to enhance feeding practices and further guarantee the health of 6-12-month-old infants in China.

A comparative study of the effects of palm olein, cocoa butter and extra virgin olive oil on lipid profile, including low-density lipoprotein subfractions in young healthy Chinese people.

The aim of this study is to investigate the effects of palm olein (POL), cocoa butter (CB) and extra virgin olive oil (EVOO) on the lipid profile and low-density lipoprotein subfractions in a young, healthy Chinese population. After screening, 72 subjects were randomly assigned to three groups, and an 18-week randomized crossover trial was conducted. The first phase was a 2-week run-in period, followed by three phases of the 4-week experimental periods with a 2-week washout period between experimental periods. Three groups of subjects alternately consumed a Chinese diet enriched with the different test oils. The various indices of subjects were collected before and after each experimental period. Sixty-seven subjects completed the study, and there were no significant differences in conventional indices amongst the three groups at the beginning of the three experimental periods (p > .05). Each test oil accounted for approximately 40% of total fat intake and approximately 11.3% of the total energy supply. After controlling for dietary interventions, only the serum triglyceride level of the POL-Diet was significantly lower than that of the EVOO-Diet (p = .034), and most indices did not significantly differ amongst the three test oil diets (p > .05). POL, CB and EVOO have almost identical effects on serum lipids.

Talaromyces marneffei is an emerging opportunistic infection among immunocompromised patients. We observe the first native case of disseminated T. marneffei involving the kidney in a renal transplant recipient in mainland China. We describe the comprehensive clinical course, and ultrasound imaging of renal transplant biopsy, pathologic images, and electron microscopy observation of the biopsy specimen, highlighting the relevance of biopsy findings and the blood culture. We also focus on the treatment and good outcome of the patient. Then we review the literature and show the additional 10 reported cases of T. marneffei in renal transplant recipients. In addition, we discuss the new methods of rapid diagnosis of T. marneffei. In brief, timely diagnosis and proper treatment of T. marneffei infection is important in renal transplant recipients.

[Meta-analysis on the relationship among fiber of grain and intestinal motility and symptoms].

OBJECTIVE: To study the relationship among fiber of grain and intestinal motility and symptoms. METHODS: To search all related data of randomized controlled trials about fiber of grain on intestinal motility and symptoms published before Jul, 2013, screen trials according to inclusion and exclusion criteria, extract data and evaluate quality by two independent researchers, and analyze data by Meta-analysis using RevMan 5.2 software. RESULTS: Thirteen researches with 739 subjects were included. According to Meta-analysis, consumption of grain fiber had more frequency of defaecation (WMD = 0.10, 95% CI 0.02 - 0.18, P < 0.05), less intestinal transit time (WMD = - 6.36, 95% CI -11.53 (-) - 1.20, P < 0.05), more fecal wet weight (WMD = 51.52. 95% CI 31.00 - 72.04, P < 0.05) than control, similar bowel side effects (SMD = 0.06, 95% CI - 0.04 - 0.16, P = 0.267), and had higher functional bowel disorder remission rate when using per protocol analysis (RR = 1.20, 95% CI 1.00 - 1.44, P =0.05 ). However, there was no significant increase of functional bowel disorder remission rate (RR = 1.16, 95% CI 0.95 - 1.41, P = 0.14) when using intention to treat analysis. CONCLUSIONS: Fiber of grain may have a positive impact on intestinal motility and no adding gastrointestinal side-effect, but may have an uncertain influence on functional bowel disorders.

[Survey on diet and nutrition intake for customers from out-home eating in Beijing].

OBJECTIVE: To assess dietary intake of customers from out-home eating, and evaluate their energy and main nutrition closely related with chronic disease consumption in one dinner. METHODS: On dinner time (lunch or supper), 2204 customers randomly selected in six middle-level table-service restaurants in Beijing, were investigated their food consumption by single-blind recording their ordered dishes weight before and after eating. According to the dish recipes, cooking way, and food composition database or measured data, food consumption and energy, protein, fat and sodium intake were evaluated. RESULTS: The mean intake of foods for a standardized man per dinner included 76 g cereals, 162 g vegetables, 11 g fruits, 128g meat, 50g fishery products, 10g eggs, 12 g legumes, 15 g pure energy food, 28 g oil, 7 g salt, 68. 1 g juice, and 7. 3 g alcohol, with 4648 kJ energy, 54. 6 g protein, 62. 3 g fat, 88. 0 g carbohydrate, 10. 7 g cholesterol and 2920 mg sodium. The percentage for energy suppliers were respectively protein 20. 7%, fat 52. 7%, carbohydrate 29. 4%. Contrast to 4180 kJ/1000 kcal energy intake, the food density for oil and salt was 2 times, and meat 3 times over that suggested by Chinese Dietary Pagoda. CONCLUSION: Out-home eating per dinner supplies nearly daily-need fat and sodium, that partially contributes to high intake of animal foods.

[Effects of fructose on triglycerides in individuals with diabetes: a Meta-analysis of experimental trials].

OBJECTIVE: To assess the effects of fructose on the blood triglycerides, particularly examining treatment dose, duration, and control of food in individuals with diabetes. METHODS: A systematic review and Meta-analysis of experimental clinical trials were conducted to investigate the effect of isocaloric fructose exchange for carbohydrate on triglycerides, total cholesterol. MedLine, EMBASE, The Cochrane Library, CMBdisc, CNKI (1970-2014), and some related journals were searched. Heterogeneity was assessed by 2 tests and quantified by I2. Meta-analysis was conducted by RevMan 5.3. RESULTS: 15 reports (21 trials) met the eligibility criteria. Isocaloric fructose exchange for carbohydrate raised triglycerides under specific conditions in individuals with type 2 diabetes. A triglyceride-raising effect without heterogeneity was seen only in type 2 diabetes when the dose was ≥ 100 g fructose/d (WMD 0.17, 95% CI0.08 - 0.25, P < 0.0001). A triglyceride-raising effect with heterogeneity was seen in type 2 diabetes when the reference carbohydrate was starch (WMD 0.13, 95% CI 0.02 - 0.23 , P = 0.02). CONCLUSION: Effect of fructose on the level of TG in type 2 diabetes patients is more sensitive than that in type 1 diabetes. The effect on triglycerides is dose dependent and depends on what kinds of carbohydrate is being exchanged with fructose.
