Objective:To evaluate the effect of different dietary pattern and soybean oligosac-charides supplementation on the amount and proportion of short-chain fatty acids (SCFA). Method: Twelve healthy students aged 20 to 25 years old were selected in the medical college. The study included 3 periods. In every period the students accepted different dietary patterns in 1st week [1. low animal food diet (LAFD),2. balanced food diet (BD), 3. high animal food diet (HAFD)]. Soybean oligosaccharides (5g/d) were added to different diets in 2nd week. The diet in 1st week was recovered in 3rd week. The study lasted for 9 w. Feces were collected once a week and SCFA was measured by capillary gas chromatography. Results: The total SCFA in feces were increased after taking LAFD, more prominent in acetic acid and butyric acid (P

Objective To analyze the nutritional composition of lipids in silkworm chrysalis (Bombyx mori L.). Method Crude lipids were extracted by chloroform/methanol, and fatty acid, tocopherol, sterol and phospholipid composition in silkworm chrysalis were determined by GC, HPLC and TLC methods. Results Silkworm chrysalis was rich in lipid (32.79%) in which the most abundant fatty acids were C18:3 (32.79%), C18:1 (32.53%), C16:0 (22.42%), but C18:2 (4.37%), C18:0 (5.73%) and C16:1 (0.57%) were relatively less. The sterols included cholesterol (67.35%), ?-sitosterol (19.21%), and trace amount of campesterol (0.28%) and brassicasterol (0.30%). Total tocopherols detected were at an average concentration of 486 mg/kg, including ?-tocopherol (44.85%), ?(+ ? )-tocopherol (44.57%), and ?-tocopherol (10.85%). The phospholipid content was about 1.17mg/g, among which, phosphorylcholine about 41.8%. Conclusion Silkworm chrystalis (Bombyx mori L.) could be a good source of nutritional edible oil rich in unsaturated fatty acid, phospholipids, phytosterols and tocopherols, particularly ?-linolenic acid, ?-sistosterol and ?-tocopherol.

Objective To investigate the role of Rho/ROCK signaling pathway in the process of human mesangial cells (HMCs) inflammation and fibrosis induced by high glucose. Methods Synchronized HMCs were divided into following groups: ( 1 ) Normal glucose control group ( NG, 5.5 mmol/L glucose); ( 2 ) High glucose group ( HG, 30 mmol/L glucose); (3) Mannitol group( Man,5.5 mmol/L glucose+ 24.5 mmol/L mannitol); (4) NG +Y-27632 group( 10 μ mmol/L Y-27632 ); ( 5 ) HG Y-27632 group ( 10 μmmol/L Y-27632 ). The supernatant and cells were collected at 0,12,24,36,48, and 72 h. Western blot was used to detect the active RhoA and total RhoA,while RhoA, ROCK-Ⅰ, CTGF, and TNF-α mRNA expressions were determined with realtime PGR method in the cells, then ELISA method was used to check protein levels of FN, CTGF, and TNF-α in the supernatant. Results ( 1 ) RhoA activation was stimulated after treatment for with 30 mmol/L glucose, peaked at 1 h, and then decreased ( P = 0. 02). (2) RhoA, ROCK-Ⅰ, CTGF, and TNF-α mRNA expressions in HMC cultured under high glucose were higher than those in the normal group ( P ＜ 0.05 ), and there was certain time-dependence. Besides, there was no statistical significance between Man and NG groups( P＞0. 05 ). ( 3 ) After Y-27632 pretreatment and being cultured with normal glucose and high glucose for24 h or48 h, RhoA, ROCK-Ⅰ, CTGF, and TNF-α mRNA expressions were significantly decreased ( P＜0.01 ) as compared with groups without treatment. (4) High glucose increased FN, CTGF,and TNF-α protein secretion of HMC in a time-dependent manner( P＜0. 05 ). ( 5 ) After Y-27632 pretreatment and being cultured with normal and high glucose for 12,24,36,48,72 h, FN, CTGF, and TNF-α protein secretions were significantly reduced( P＜0.05 ). Conclusion Rho/ROCK signaling pathway may mediate inflammation and fibrosis induced by high glucose in HMCs, supporting a potential role for inhibitors of Rho/ROCK in the treatment of diabetic nephropathy.

Objective To study the expression and the mechanism of miR-155in the villi of patients with unexplained recurrent spontaneous abortion (URSA).Methods The expression of miR-155 in the villi of 36 cases with URSA (URSA group) and 25 women with normal early pregnancy (control group) were detected by stem-loop real-time reverse transcription (RT) qPCR.Expression of hypoxia inducible factor-1 (HIF-1α),vascular endothelial cell growth factor(VEGF) and micro lymphatic vessel density (MVD) in the villi of were measured by immnohistochemical staining among two groups.Results (1) miR-155 expression:the mean miR-155 expression were 1.456 (0.489,2.459) in URSA group and 2.833 (1.740,3.794) in control group,which reached statistical difference (P ＜0.05).The mean expression of miR-155 of 1.683 (0.902,2.459) in URSA group with abortion times (≤ 3) was significantly higher than 1.229 (0.489,1.719) in URSA group with more than 4 times abortion (P ＜ 0.05).(2) Indexes:the expression of HIF-1α,VEGF and MVD value were 121 ± 12,134 ± 12,36 ± 6 in URSA group and 99 ± 10,109 ± 10,28 ±4 in control group,which reached statistical difference(P ＜ 0.01).The expression of HIF-1α,VEGF and MVD value of 119 ± 12,134 ± 12,35 ± 5 in URSA group with less than 3 times abortion was significantly lower than 128 ± 12,138 ± 12,43 ± 6 in URSA group with more than 4 times abortion (P ＜ 0.01).Conclusions The expression of miR-155 and HIF-1α is topically stimulated by oxygen signal.HIF-1α adjusts the transcription and translation of VEGF,which together involved in placental trophoblast invasion and placental angiogenesis.The low expression of miR-155 could interfere with expression of HIF-1α and VEGF,which might be involved in villous vascular dysplasia in URSA.

Objective To investigate the distribution of eosinphililic neurons ( ENs),reactive astrocytes ( RAs),and infarction after transient cerebal ischemia,and the time profile of pathomorphological changes.Methods Unilateral forebrain ischemia was induced in Mongolian gerbils by two 10 minutes unilateral common carotid artery occlusions with a 5 hours interval.Laser Doppler flowmetry was used to detect intra-ischemic anterior cortex blood flow.Animals were sacrificed at 24 hours,4 days,2 weeks,4 weeks,16 weeks and the brain were prepared for pathomorphological assay.Results Intra-ischemic laser Doppler flowmetry show significant ischemia during carotid artery occlusion:22.1％ ± 9.5％,26.3％ ± 4.9％,37.5％ ± 3.5％,F =67.219,P ＜ 0.01 ; the decrease was significantly greater in the anterior cortex.ENs appeared in middle and deep layers at 24 hours postischemia,and ENs area extend to all layers of cortex by 4 days.Large areas of high EN density ( ≥80/mm2) evolved to infarcts between 4 days and 4 weeks.Posterior cortex evolved to low EN area ( ＜ 80/mm2) without transformation into infarcts.RAs were consistently distributed in areas with ENs,and RA areas with high EN density were largely transformed into infarcts between 4 days and 4 weeks. Delayed astrocytic death took place in the RA areas with high EN density.Conclusion Density of ENs is an important indicator of delayed astrocytic death and infarction in postischemic tissue.

Objective: To investigate the relationship between after-school schedule and bone mineral density in middle-school students in Shanghai, to provide a reference for taking targeted measures. Methods: From November 2017 to April 2018，eighteen classes of six middle schools in Shanghai (from urban districts, urban-suburb combined districts and suburban districts, respectively) were selected based on cluster random sampling. In each school, 2-4 classes were further randomly chosen in the 6th grade. Questionnaires were completed by 518 students and their parents, as well as physical examination and bone mineral density assessment. Results: The average time spent on after-school academic learning during weekends was 4.0 (IQR: 2.0, 6.0) h. The Z-score of bone density was 0.3 (IQR: -0.7, 1.0). The smooth curve fit model showed a non-linear relationship between after-school academic learning time during weekends and the Z-scores of bone mineral densities. A two-stage multiple linear regression analysis was further applied according to the fit results, and the results showed that when total afterschool academic learning time <4.5 hours during weekends, the learning time was inversely correlated with the bone density Z-scores (β=-0.11,P=0.01), and when the learning time ≥4.5 hours, there was no significant correlation between the learning time and bone density Z-scores (β=0.02, P=0.65). Parent and student questionnaires showed that there was a non-linear relationship between students’ daily time spent on outdoor sports-related activities and bone density Z-scores. When time spent on the outdoor activities ≥45 minutes per day, outdoor activities were positively correlated with bone density Z-scores (P<0.05). However, when the time spent on outdoor activities <45 minutes per day, there was no significant relationship between outdoor activities and bone density Z-scores (P>0.05). Conclusion Too much time on after-school academic learning during weekends or limited time on outdoor activities are both related to impaired bone mineral densities. Therefore, a reasonable after-school schedule for middle-school students is important for physical development, especially during weekends.
