Through single and compound formula preservative test, the results showed that potassium sorbate and sodium dehydroacetate could inhibit the microorganisms in the moon cake, but the inhibitory effect of sodium dehydroacetate was stronger than that of potassium sorbate; and the combination of potassium sorbate and sodium dehydroacetate had a synergistic effect, and the best formula is ＇potassium sorbate 0.44 g/kg mixed with sodium dehydroacetate 0.38 g/kg. A batch of moon cake was prepared with the best preservative formula, then the total number of colonies, molds and coliform group in the samples were detected by random sampling at irregular intervals. The total number of molds exceeded the limit on the 187^th d, and it indicated that the shelf life of the product was 187 d. Compared with the conventional 15-day shelf life, this research greatly prolongs the sheff life of cantonese style moon cake, and cut down the cost of moon cake enterprises. It is worthy of popularization and application.展开更多

METHODS： Eighty-five rats were divided into four groups： control, model, Huogu 15 g/kg and Huogu 30 g/kg. Six weeks later, animals were anaesthe- tized, femora were dissected for histopathologicalexamination of the osteonecrotic changes and re- pair processes, micro computed tomography （Mi- cro-CT）-based micro-angiography was performed to assess vascularization. Serum lipid levels were detected by haematological examination. The ex- pressions of PPARy, Wnt3a, low density lipoprotein receptor-related protein 5 （LRP5） and 13-catenin were evaluated by immunohistochemistry, Western blot and quantitative real-time polymerase chain reaction analyses. RESULTS： The incidence of osteonecrosis, ratio of empty lacuna, adipose tissue area and adipocyte perimeter in the bone marrow were dramatically lower in the Huogu ~ formula treatment groups. By micro-CT quantification, Huogu ~ formula treat- ment dose-dependently increased vessel volume, vessel surface, percentage of vessel volume and vessel thickness of the femoral heads of SONFH rats. Levels of serum lipid in Huogu 15 g/kg and Huogu 30 g/kg groups reduced significantly. HuoguⅠformula treatment could suppress the ex- pression of PPARy and increase the expressions of Wnt3a, LRP5 and 13-catenin at both protein and mRNA levels. CONCLUSION： The results of our present study highlight the lipid-lowering potential of Huogu Ⅰ formula, and provide further evidence of the in- volvement of the PPARy inhibition and Wnt/LRPS/ 13-catenin signaling activation in the effects of Huogu Ⅰ formula.展开更多

Although XFBD has exhibited significant therapeutic efficacy in clinical practice, its underlying pharmacological mechanism remains unclear. Here, we combine a comprehensive research approach that includes network pharmacology, transcriptomics, and bioassays in multiple model systems to investigate the pharmacological mechanism of XFBD and its bioactive substances. High-resolution mass spectrometry was combined with molecular networking to profile the major active substances in XFBD. A total of 104 compounds were identified or tentatively characterized, including flavonoids, terpenes, carboxylic acids, and other types of constituents. Based on the chemical composition of XFBD, a network pharmacology-based analysis identified inflammation-related pathways as primary targets. Thus, we examined the anti-inflammation activity of XFBD in a lipopolysaccharide-induced acute inflammation mice model. XFBD significantly alleviated pulmonary inflammation and decreased the level of serum proinflammatory cytokines. Transcriptomic profiling suggested that genes related to macrophage function were differently expressed after XFBD treatment. Consequently, the effects of XFBD on macrophage activation and mobilization were investigated in a macrophage cell line and a zebrafish wounding model. XFBD exerts strong inhibitory effects on both macrophage activation and migration. Moreover, through multimodal screening, we further identified the major components and compounds from the different herbs of XFBD that mediate its anti-inflammation function. Active components from XFBD, including Polygoni cuspidati Rhizoma, Phragmitis Rhizoma, and Citri grandis Exocarpium rubrum, were then found to strongly downregulate macrophage activation, and polydatin, isoliquiritin, and acteoside were identified as active compounds. Components of Artemisiae annuae Herba and Ephedrae Herba were found to substantially inhibit endogenous macrophage migration, while the presence of ephedrine, atractylenolide I, and kaempferol was attributed to these effects. In summary, our study explores the pharmacological mechanism and effective components of XFBD in inflammation regulation via multimodal approaches, and thereby provides a biological illustration of the clinical efficacy of XFBD.展开更多

The refractive error changing rate for the cornea and lens power, the axial length, anterior chamber depth(ACD) and vitreous chamber depth(VCD) are calculated, including nonlinear terms for more accurate rate functions than the linear theory. Our theory, consistent with the empirical data, shows that the Pearson correlation coefficients for spherical equivalent(SE) and ocular components are highest for SE with axial length, ACD and VCD and weakest for corneal power, lens power and lens thickness. Moreover, our regression formulas show the asymmetric feature of the correlation that the axial length, ACD and VCD are more strongly correlated(with higher negative regression constants) with refractive errors in eyes with hyperopia than in eyes with myopia, particularly for severe hyperopia.展开更多

Bone mineral density(BMD) at the lumbar vertebrae, histology, bone markers and serum levels of estrogen were assessed. Furthermore, a cohort study was conducted in 130 postmenopausal women with breast cancer that had undergone treatment with AIs. The subjects were given JPBS + caltrate D or caltrate D only, administered orally. BMD at the lumbar vertebrae and femoral neck and bone markers were evaluated in both control and herbal treatment groups at baseline and 12 months.RESULTS: Experimental results indicated that a high dose of JPBS significantly increased the trabecular bone area percentage(Tb.Ar %) and broadened the trabecular thickness(Tb.Th). The JPBS formula enriched the carboxyterrninal propeptide of type ipmcollagen and increased serum estrogen level significantly. The clinical investigation revealed that bone loss was decreased in the group treated with JPBS vs control(BMD T score at lumbar vertebrae, 3.9% increased vs 14.58% decreased, respectively, P = 0.004 and BMD T score on femoral neck, 1.8% decreased vs 22.45% decreased, respectively, P = 0.008). Besides, JPBS formula elevated Nmiddle osteocalcin and decreased type Ⅰ collagen cross-linked C-terminal telopeptide.CONCLUSION: JPBS formula prevented aromatase-inhibitor-associated bone loss after menopause by inhibiting bone resorption and promoting bone formation.展开更多

Methods: Analysis was performed on 120 outpatient and inpatient POPs treated in our hospital between January and October 2013, where the patients were randomly divided into Qing’E group (QEF + Caltrate), Calcitriol group (Caltrate + Calcitriol soft capsules), and Compare group (Caltrate), each with a follow-up period of 1 year. Statistical analysis was then performed on bone mineral density, blood bone metabolic markers (β-CTX, N-MID, T-PINP) and changes in VDR mRNA expressions in the POPs before and after the treatments. Results: Prior to the treatments, bone mineral density and blood β-CTX, N-MID, T-PINP and VDR mRNA expression in the 3 groups of POPs exhibited no statistically significant differences, and the blood β-CTX, N-MID, T-PINP and VDR mRNA expression in the control group showed no statistically significant differences before and after the treatments. There were no significant differences in bone mineral density in the Qing’E group and the Calcitriol group before and after the treatments whereas the bone mineral density decreased in the control group after the treatments. As for blood β-CTX, N-MID, T-PINP and VDR mRNA expression, the measurements in POPs in the Qing’E group and the Calcitriol group were significantly higher than that of the control group. Conclusion: By adjusting the VDR mRNA expression, the QEF, a kidney-invigorating Chinese herbal formula, is capable of activating bone metabolism to prohibit further losses of bone mass, thereby preventing the deterioration of osteoporosis.展开更多

The refractive error changing rate for the cornea and lens power, the axial length, anterior chamber depth(ACD) and vitreous chamber depth(VCD) are calculated, including nonlinear terms for more accurate rate functions than the linear theory. Our theory, consistent with the empirical data, shows that the Pearson correlation coefficients for spherical equivalent(SE) and ocular components are highest for SE with axial length, ACD and VCD and weakest for corneal power, lens power and lens thickness. Moreover, our regression formulas show the asymmetric feature of the correlation that the axial length, ACD and VCD are more strongly correlated(with higher negative regression constants) with refractive errors in eyes with hyperopia than in eyes with myopia, particularly for severe hyperopia.

文摘OBJECTIVE: To investigate the effect of Jianpi Bushen(JPBS) formula on aromatase inhibitor(AI)-associated bone loss after menopause.METHODS: Six-month-old female rats were randomly divided into 6 groups: a sham group, an ovariectomized(OVX) group, an OVX treated with exemestane and 3 OVX groups each treated with a different dose of JPBS formula. Bone mineral density(BMD) at the lumbar vertebrae, histology, bone markers and serum levels of estrogen were assessed. Furthermore, a cohort study was conducted in 130 postmenopausal women with breast cancer that had undergone treatment with AIs. The subjects were given JPBS + caltrate D or caltrate D only, administered orally. BMD at the lumbar vertebrae and femoral neck and bone markers were evaluated in both control and herbal treatment groups at baseline and 12 months.RESULTS: Experimental results indicated that a high dose of JPBS significantly increased the trabecular bone area percentage(Tb.Ar %) and broadened the trabecular thickness(Tb.Th). The JPBS formula enriched the carboxyterrninal propeptide of type ipmcollagen and increased serum estrogen level significantly. The clinical investigation revealed that bone loss was decreased in the group treated with JPBS vs control(BMD T score at lumbar vertebrae, 3.9% increased vs 14.58% decreased, respectively, P = 0.004 and BMD T score on femoral neck, 1.8% decreased vs 22.45% decreased, respectively, P = 0.008). Besides, JPBS formula elevated Nmiddle osteocalcin and decreased type Ⅰ collagen cross-linked C-terminal telopeptide.CONCLUSION: JPBS formula prevented aromatase-inhibitor-associated bone loss after menopause by inhibiting bone resorption and promoting bone formation.

文摘Superalloys feature multi-elements and complex elemental ranges,which makes the proper composition selection difficult.In fact,more strict composition standards generally apply in practical productions.The objective of this paper is to understand and eventually to renew the composition standard via example of the most common grade Inconel 718.We have recently shown that t he alloy chemistry originates from a nearest-neighbor cluster[center-shell]plus a few next-neighbor glue atoms,or expressed in cluster for-mula[center-shell](glue atoms).By grouping the elements into Ni=(Ni,Co,Cu,Fe),Cr=(Cr,Mn,Si,Mo),and Nb=(Nb,Al,Ti),it is found that the reported alloys fall within a narrow composition zone Ni_(11.0-13.0)-Cr_(3.5-4.5)-Nb_(1) confined by cluster formulas of 16 and 18 atoms.This composition zone is also expressed in terms of 288-atom supercluster formulas,Ni_(198-208)-Cr_(63-72)-Nb_(16-18),which leads to coordi-nated elemental variations in wt.%:69.0≤Ni+Co+Cu+Fe≤72.7;19.8≤Cr+Mn+1.7 Si+0.6 Mo≤22.8;8.7≤Nb+3.2 Al+1.9 Ti≤9.8.Within this composition zone,Ni_(206)-Cr_(65.5)-Nb_(16.5) is further pinpointed and validated by our own experiments to possess the optimal match of strength and plasticity both at room and at 923 K.
文摘Objectives: To study the partial mechanism of treating postmenopausal osteoporosis patients (POPs) using the ancient recipe of Qing’E Formula (QEF) by observing its effects on bone metabolic markers and VDR mRNA expression in primary POPs. Methods: Analysis was performed on 120 outpatient and inpatient POPs treated in our hospital between January and October 2013, where the patients were randomly divided into Qing’E group (QEF + Caltrate), Calcitriol group (Caltrate + Calcitriol soft capsules), and Compare group (Caltrate), each with a follow-up period of 1 year. Statistical analysis was then performed on bone mineral density, blood bone metabolic markers (β-CTX, N-MID, T-PINP) and changes in VDR mRNA expressions in the POPs before and after the treatments. Results: Prior to the treatments, bone mineral density and blood β-CTX, N-MID, T-PINP and VDR mRNA expression in the 3 groups of POPs exhibited no statistically significant differences, and the blood β-CTX, N-MID, T-PINP and VDR mRNA expression in the control group showed no statistically significant differences before and after the treatments. There were no significant differences in bone mineral density in the Qing’E group and the Calcitriol group before and after the treatments whereas the bone mineral density decreased in the control group after the treatments. As for blood β-CTX, N-MID, T-PINP and VDR mRNA expression, the measurements in POPs in the Qing’E group and the Calcitriol group were significantly higher than that of the control group. Conclusion: By adjusting the VDR mRNA expression, the QEF, a kidney-invigorating Chinese herbal formula, is capable of activating bone metabolism to prohibit further losses of bone mass, thereby preventing the deterioration of osteoporosis.

文摘Psoriasis,a prevalent inherited skin condition,involves an inflammatory response as a key pathogenic mechanism.The Optimized Yinxieling Formula(OYF),rooted in traditional Chinese medicine,is extensively utilized in clinical settings to treat psoriasis.Although previous studies have demonstrated OYF’s significant anti-inflammatory effects in psoriasis,its potential molecular targets and active components remain unexplored.This study aimed to unveil the anti-psoriasis molecular targets and active components of OYF.Our findings indicated that OYF extract markedly reduced the production of several inflammatory mediators,including IL-23,nitric oxide,TNF-α,and IL-1β,in LPS-induced RAW264.7 cells.We synthesized OYF extract-crosslinked beads to isolate pharmacological targets from RAW264.7 lysates using an affinity purification strategy,known as Target Fishing.The enriched target proteins were subsequently identified via LC-MS/MS,followed by bioinformatics analysis to map the psoriasis-associated pathway-gene network.We identified a total of 76 potential target proteins,which were highly associated with mRNA transcription mechanisms.In particular,pathway-gene network analysis revealed that the IL-23 inflammatory pathway was involved in the anti-psoriasis effect of OYF extract.We further utilized a target protein-based affinity capture strategy,combined with LC-MS and SPR analysis,to globally screen OYF’s active components,focusing on the mRNA transcription regulator,fused in sarcoma(FUS).This process led to the identification of umbelliferone,vanillic acid,protocatechuic acid,gentisic acid,and echinacoside as key compounds targeting FUS to inhibit IL-23 expression.Additionally,we formulated a compound cocktail(CpdC),which significantly reduced psoriasis area and severity index(PASI)scores and the expressions of IL-23 and Ki67 in an imiquimod(IMQ)-induced psoriasis mouse model.Collectively,our study elucidates the primary molecular targets and active components of OYF,offering novel insights for psoriasis treatment.
