| 1 | Isolation and identification of novel casein-derived bioactive peptides and potential functions in fermented casein with Lactobacillus helveticus显示文摘The present study here establishes a complete and effective method for isolating,purifying and identifying extracellular and intracellular peptides,and also describes the characters and bioactivities of peptides from fermented casein with Lactobacillus helveticus.Intracellular peptides are much larger in quantity and more complex in composition than extracellular peptides,between which the correlation reveals proteolytic and metabolic mechanisms.In addition,totally 241 different peptide sequences were identified by Nano LC–MS/MS from casein(212)and Lactobacillus helveticus proteins(29).These casein-derived peptides mostly originated from-casein,followed byS1-casein,-casein,andS2-casein,and came from extracell(69)and intracell(143),in which common peptides have a total of 27.Forty-four of the identified peptides were previously described as bioactive,including angiotensinconverting enzyme(ACE)-inhibitory,antioxidant,immunomodulating,antimicrobial,DPP-IV inhibitory,antiamnesic and anticancer effects and so on.Thirteen peptides with the potential of some biological activities are obtained,which were described in previous studies.A total of 47 novel peptides of 5 to 26 amino acids that were not disclosed were obtained.The new sources of natural bioactive peptides may have the very high application value as potential new peptide drugs for treatment human diseases.The product peptide DELQDKIHPF found in both extracell and intracell was quantitatively analyzed using the MRM mode of UPLC-U3Q,23.1 and 9.76 ng/mL,respectively.The quantitative analysis of the potential bioactive peptide may also advance the production of peptide products in the future. | Mengzhu Fan Tingting Guo Wanru Li Jing Chen Fushuo Li Chao Wang Yi Shi David Xi-an Li Shaohui Zhang | 2019 | Food Science and Human Wellness2019，8，2： | 5 |

| 6 | Regular diet is non-inferior to restricted diet after polypectomy with decreased hospitalization length of stay and cost:a randomized–controlled trial显示文摘Background There are no data comparing a regular diet with a restricted diet after endoscopic polypectomy in patients with colorectal polyps.The current guidelines also did not provide the detailed information of dietary patterns after polypectomy.In this study,we aimed to evaluate the safety and efficacy of different diets on post-polypectomy outcomes.Methods A total of 302 patients with colorectal polyps who underwent polypectomy were prospectively enrolled between March 2019 and December 2019 in Nanfang Hospital(Guangzhou,China).Enrolled patients were then randomly assigned to a regular diet group or a restricted diet group after polypectomy.The study is a non-inferior design and the primary end point was the post-operative adverse events(AE)rate.Secondary end points included length of stay(LOS)and hospitalization cost.Results Among all the included patients,148 patients received a restricted diet and 154 patients received a regular diet after polypectomy.A total of 376 polyps were removed,with 183 polyps in the restricted diet group and 193 polyps in the regular diet group.Shorter LOS(4.0±1.4 vs 4.8±1.7,P<0.001)and lower hospitalization costs(7,701.63±2,579.07 vs 8,656.05±3,138.53,P=0.001)were observed in the regular diet group.In particular,there was no significant difference in 3-day AE rates between the restricted diet and the regular diet group(1.35%[2/148]vs 2.60%[4/154],P=0.685).Subgroup analysis looking at the number of polyps removed in each patient and different treatmentmodalities also showed similar findings.Conclusion Regular diet should be recommended after polypectomy for polyps<20mm as it can shorten LOS and save hospitalization costs. | Rong Huang Shaohui Huang Li Xu Rai Mandip Baomei Chen Jiayi Fan Yang Bai Yusi Wang Zelong Han Zhiqing Wang Side Liu Yue Li | 2022 | Gastroenterology Report2022，10，1： | 0 |
| 7 | Response of growth,metabolism and yield of Dendrocalamopsis oldhami to long-day photoperiod and fertilizer compensation显示文摘The effects of long-day photoperiod on growth,photo synthetic fluorescence,carbon and nitrogen metabolism,and yield of Dendrocalamopsis oldhami and the compensation effects of fertilization were investigated.A completely randomized design was used with two light factors(bamboo culms cultivated in solar greenhouse under long-day[Ls]and short-day[Ln]treatments);two organic nitrogen fertilizer levels(application of organic fertilizer[OF]and no organic fertilizer[NF]);and three nitrogen fertilizer levels(Low[N0],medium[N1]and high nitrogen[N2]).Leaf chlorophyll and fluorescence parameters(φPo,PIABS,and ETo/CSm)decreased and DIo/CSmincreased in Ls compared to Ln.Indole acetic acid(IAA)and gibberellic acid(GA3)levels decreased,whereas abscisic acid(ABA)increased.Leaf area decreased and leaf dry mass increased.The contents of carbon and nitrogen metabolism-related enzymes(nitrate reductase,glutamine synthetase,amylase,and sucrose synthase)and products(total nitrogen,organic carbon,soluble sugar,and starch)increased.Single bamboo shoot weight and diameter at breast height decreased,whereas shoot quantity and total yield increased.Fertilizer application significantly affected physiological growth and yield in the two light treatments,thus promoting carbon and nitrogen metabolism.TheφPo,PIABS,IAA,and GA3contents increased slightly,whereas ABA levels decreased.Shoot quantity,individual weight,and total yield improved.IA A,soluble sugar,and total yield to organic manure and light were lower than those of nitrogen levels(FN>FL,FO).Other indicators showed lower responses to different fertilization treatments than the light factor(FL>FN,FO).The ability of D.oldhami to alter its morphological and physiobiochemical traits and yield in response to variations in light applications may translate into high phenotypic plasticity.Fertilization significantly improved photoplasticity of D.oldhami.Under Ls,D.oldhami had high metabolic rates.was easily inhibited by light,and showed accelerated leaf senescence,and shoot quantity and total output increased.However,the quality of individual shoots decreased.Different fertilization treatments affected D.oldhami differently under the two light intensities.Ls sensitivity to nitrogen was higher.Fertilization could delay leaf dormancy and senescence under Ls treatment.Organic fertilizer addition could improve yield more effectively,with OFN1being the optimal fertilization level. | Zixu Yin Shaohui Fan Wen Xia Yang Zhou Xiao Zhou Xuan Zhang Chengji Li Fengying Guan | 2023 | Journal of Forestry Research2023，34，1： | 0 |
| 8 | Study on Litter Water Interception Capacity of Phyllostachys edulis Plantations with Different Densities显示文摘The litter amount and the water holding characteristic parameters,such as the maximum water holding capacity and rate,the water absorption rate and the modified interception amount of Phyllostachys edulis plantations with four densities were studied in Huangshan district.The results are as follows:The total amount,thickness and natural water content of litters under all the four stands tested were different.The total litter amount in different stands ranged between 3.98 t·ha-1 to 6.00 t·ha-1, which in the stand with the density of 3 000 stems·ha-1 was the most.The ratio of maximum water-holding capacity of litter in various stands ranged from 317.09%to 347.58%.The maximum water holding capacity of litter in the stand with the density of 3 000 stems·ha-1 was 20.70 t·ha-1. By analyzing,the relationship between the water holding capacity of litter and the immersion time followed the equation of:S = alnt + b(a is the coefficient;b is the constant term).The relationship between the water absorption speed of the litter and the immerse time followed the equation of: V = ctd(c is the coefficient;d is the exponential term).The litter water capacity increased rapidly within the first four hours,and then increased slowly.The results also showed that the hydrological character of litter was positively related to density in Ph.Edulis forest.Therefore, it is important to choose appropriate density for enhancing the eco-hydrological benefits of litter layer in Ph.edulis forest. | Yu Lin Fan Shaohui Su Wenhui LiuWeiyi Feng Huanying | 2012 | Chinese Forestry Science and Technology2012，11，3： | 0 |
| 9 | Study on Cultivation Nutrition of Cunninghamia lanceolata Plantations with Multi-generation Management显示文摘Based on the previous study on cultivation nutrition of Cunninghamia lanceolata plantations of first generation, the cultivation nutrition of C. lanceolata plantations with multi-generation was studied. The results show that there are significant differences in the growth, development and nutrient assimilation among C. lanceolata plantations with different generations and nutrition conditions. These differences are closely related to the land fertility decline of C. lanceolata plantations. This paper de... | FAN Shaohui MA XiangqingResearch Institute of Forestry. CAP. Beijing 100091.

| 10 | Changes in foliar nitrogen resorption of Phyllostachys edulis with culm development显示文摘Leaf nitrogen resorption is very important to Phyllostachys edulis development because the withdrawn nitrogen can help newly emerging and growing culms.However, few studies have focused on the ontogenetic changes in leaf nitrogen resorption of P. edulis. Here, we examined the variability in mature leaf nitrogen concentrations(Nm), nitrogen resorption efficiency(NRE) and proficiency(NRP or Ns) and leaf-level nitrogen use efficiency(NUE) of the current-, 3 rd-and 5 th-year culms in P.edulis stands under extensive management. Analyses of variance and correlation indicated that patterns of Nm,NRP, NRE and NUE were markedly affected by culm age and leaf nitrogen status. Nm, Nsand NRE were significant higher in younger(current-year) culms with 1-year lifespan leaves, while NUE was markedly higher in older(3 rd-or 5 th-year) culms with 2-year lifespan leaves. Significant linear correlations between Nmand NRP, NRE and NUE,Nmand NUE, Nsand NRE were found for each culm age,and Nmwas significantly positively correlated to NRE for all culms pooled. Higher proficiency in older culms led to higher NUE and lower NRE, these relationships can be modulated by Nm, which in turn, is restrained by leaf N availability and acquisition. Our results revealed that at the intraspecific level, P. edulis can adjust its leaf NRE, NRP,and leaf-level NUE in concert with culm development.Understanding nitrogen resorption characteristics and NUE of P. edulis can help decision-makers design appropriate deforestation strategies and achieve precise N fertilization for sustainable bamboo forest management. | Changshun Zhang Chunlan Liu Wenyuan Zhang Gaodi Xie Shaohui Fan Na Li | 2019 | Journal of Forestry Research2019，30，2： | 0 |
