Abstract
Aim:Andrographis paniculata (Burm. f.) Nees (also known as Chuanxinlian in Chinese) of Acanthaceae family is one of the Chinese herbs reputed to be effective in the treatment of inflammation, infection, cold, and fever. Enterovirus 71 (EV71) is one of the most important enteroviruses that cause hand, foot, and mouth disease (HFMD) accompanied with neurological complication. Methods: To explore an anti-infective Chinese herb medicine, pure compounds isolated or synthesized analogues from A. paniculata (AP) ethyl acetate (EtOAc) extract are used to explore their anti-EV71-induced cytotoxicity. The antiviral activity was determined by cytopathic effect (CPE) reduction, and sub-G1 assays were used for measuring lysis and apoptosis of EV71-infected rhabdomyosarcoma (RD) cells. IFNγ-driven luciferase reporter assay was used to evaluate their potential roles in activation of immune responses. Results: Our data showed that EV71-induced sub-G1 phase of RD cells was dose dependently increased. Highly apoptotic EV71-infected RD cells were reduced by AP extract treatment. Ergosterol peroxide (4) has the most anti-apoptotic effect among these seven compounds. In addition, 3,19-O-acetyl-14-deoxy-11,12-didehydroandrographolide (8) synthesized from acetylation of compound 7 showed significantly better antiviral activity and the lowest sub-G1 phase of 6%–18%. Further investigation of IFNγ-inducer activity of these compounds showed that compounds 3, 6, 10, 11, and 12 had significantly higher IFNγ luciferase activities, suggesting their potential to promote IFNγ expression and thus activate immune responses for antivirus function. Conclusion: Our study demonstrated that bioactive compounds of AP and its derivatives either protecting EV71-infected RD cells from sub-G1 arrest or possessing IFNγ-inducer activity might be feasible for the development of anti-EV71 agents.

Abstract
Systemic lupus erythematosus (SLE) is an autoimmune disease of unknown etiology, although its mechanisms involve genetic, epigenetic and environmental risk factors. Considering that SLE pathogenesis is yet to be explored, recent studies aimed to investigate the impact of diet, in terms of triggering or altering the course of the disease. To study the impact of diet on SLE pathogenesis, we conducted a search on Pubmed using the keywords 'diet and autoimmune diseases', 'diet and lupus', 'caloric restriction and lupus', 'polyunsaturated fatty acids and lupus', 'vitamin D and lupus', 'vitamin C and lupus' 'vitamin E and lupus' 'vitamin A and lupus' 'vitamin B and lupus', 'polyphenols and lupus', 'isoflavones and lupus', 'minerals and lupus', 'aminoacids and lupus', 'curcumin and lupus' and found 10,215 papers, from which we selected 47 relevant articles. The paper clearly emphasizes the beneficial role of personalized diet in patients with SLE, and the information presented could be used in daily practice. Proper diet in SLE can help preserve the body's homeostasis, increase the period of remission, prevent adverse effects of medication and improve the patient's physical and mental well-being.

Coumestrol inhibits autoantibody production through modulating Th1 response in experimental autoimmune thyroiditis. Oncotarget 2018; 7:52797-52809.

Abstract
Coumestrol is a common phytoestrogen found in plants and Chinese medicinal herbs. Its influences on experimental autoimmune thyroiditis (EAT) were investigated in this study. Female adult CBA/J mice were fed with drinking water containing 1% Tween80 only (Control group), 0.8 mg/l (L group) and 8 mg/l coumestrol (H group) from 6 to 15 weeks of age, respectively. Their serum coumestrol concentrations were determined by high performance liquid chromatography, which were undetectable, 43.70 ± 21.74 ng/ml and 135.07 ± 70.40 ng/ml, respectively. In addition, the mice (n = 14–16/group) were immunized twice with thyroglobulin (Tg) and Freund's adjuvant to induce EAT during the meantime. Although no overt changes in the extent of intrathyroidal mononuclear cell infiltration were shown in the two coumestrol-treated groups as compared with the controls, serum anti-Tg IgG2a, IgG3 and IgG1 titers, ratio of IgG2a to IgG1 and the percentage of T helper (Th)1 cells in the splenocytes were significantly reduced in the L group. Another consistent change was the significantly decreased expression of splenic IFN-γ mRNA after low dose of coumestrol exposure. Uterine weight was also markedly reduced in the mice of L group. These findings suggest that coumestrol treatment may have some beneficial actions against thyroid-specific autoantibody production in the development of autoimmune thyroiditis through suppression of Th1 response due to its anti-estrogenic activity.

Abstract
AbstractSystemic lupus erythematosus (SLE) is a chronic inflammatory and autoimmune disease characterised by multiple organ involvement and a large number of complications. SLE management remains complicated owing to the biological heterogeneity between patients and the lack of safe and specific targeted therapies. There is evidence that dietary factors can contribute to the geoepidemiology of autoimmune diseases such as SLE. Thus, diet therapy could be a promising approach in SLE owing to both its potential prophylactic effects, without the side effects of classical pharmacology, and its contribution to reducing co-morbidities and improving quality of life in patients with SLE. However, the question arises as to whether nutrients could ameliorate or exacerbate SLE and how they could modulate inflammation and immune function at a molecular level. The present review summarises preclinical and clinical experiences to provide the reader with an update of the positive and negative aspects of macro- and micronutrients and other nutritional factors, including dietary phenols, on SLE, focusing on the mechanisms of action involved.

Abstract
Cytokines play the active roles in the pathogenesis of systemic lupus erythematosus (SLE) and contribute significantly to the immune imbalance in this disease. Conservative therapeutic approaches, such as dietary modifications have been shown to have some beneficial impact on the disease activity of the SLE. Over the past years, accumulating evidences have supported a major role for specific dietary factors, including calorie restriction, n-3/n-6 fatty acids, vitamin A, vitamin D, vitamin E, phytoestrogens or herbal medicine in the regulation of cytokines involved in SLE development. Although there are many reviews that discuss the issue of nutrition and immunity, there are relatively few articles that focus on the regulation of cytokines by dietary factors. This concise review will summarize those animal studies that investigated not only the outcome of autoantibody production and proteinuria, but also cytokines production. However, the field of dietary factors in the immunomodulation of SLE is still in its infancy. More clinical studies are needed to confirm the preliminary results and advance the knowledge in this field. Lifestyle modification and adjustments in diet are important and encouraged to be suggested as an adjuvant therapy for SLE.

Abstract
CKD is a major public health problem in the developed and the developing world. The degree of proteinuria associated with renal failure is a generally well accepted marker of disease severity. Agents with direct antiproteinuric effects are highly desirable therapeutic strategies for slowing, or even halting, progressive loss of kidney function. We review progress on therapies acting further downstream of the renin-angiotensin-aldosterone system pathway (e.g., transforming growth factor-beta antagonism, endothelin antagonism) and on those acting independent of the renin-angiotensin-aldosterone system pathway. In all, we discuss 26 therapeutic targets or compounds and 2 lifestyle changes (dietary modification and weight loss) that have been used clinically for diabetic or nondiabetic kidney disease. These therapies include endogenous molecules (estrogens, isotretinoin), biologic antagonists (monoclonal antibodies, soluble receptors), and small molecules. Where mechanistic data are available, these therapies have been shown to exert favorable effects on glomerular cell phenotype. In some cases, recent work has indicated surprising new molecular pathways for some therapies, such as direct effects on the podocyte by glucocorticoids, rituximab, and erythropoietin. It is hoped that recent advances in the basic science of kidney injury will prompt development of more effective pharmaceutical and biologic therapies for proteinuria.

Abstract
Coumestrol has long been known as the phytoestrogenic compound in alfalfa. However, it has been demonstrated that the ethyl acetate extract of alfalfa sprout (AEA) attenuated the disease severity and increased survival and life span of autoimmune-prone MRL-lpr/lpr mice. Coumestrol, on the contrary, decreased the survival. This study thus aimed to isolate and identify phytoestrogenic compounds other than coumestrol in AEA. AEA was fractionated and separated by successive silica gel chromatography and preparative HPLC. The activity of collected fractions was tracked by a transactivation assay for ERα and ERβ, respectively. In addition to coumestrol, liquiritigenin, isoliquiritigenin, loliolide, and (4S,6S)- and (4R,6S)-4-hydroxy-6-pentadecyltetrahydropyr-2-one were isolated and chemically identified. Except for loliolide, these compounds showed higher transactivation via ERβ than via ERα. The maximal activation via ERα of coumestrol reached 80% that of 1 nM 17β-estradiol (E(2)), whereas the activations of the remaining five compounds as well as AEA ranged from 8 to 49%. In addition, isoliquiritigenin, loliolide, and (4S,6S)- and (4R,6S)-4-hydroxy-6-pentadecyltetrahydropyr-2-one, but not coumestrol, preferentially inhibited 1 nM E(2) induced ERα activation, compared to that ERβ activation. The selectivity of these phytoestrogens might account for the difference between the effects of AEA and coumestrol in autoimmune-prone MRL-lpr/lpr mice observed previously.

Ethyl acetate extracts of alfalfa (Medicago sativa L.) sprouts inhibit lipopolysaccharide-induced inflammation in vitro and in vivo. J Biomed Sci 2009; 16:64.

Abstract
This study aimed to investigate if food components that exert anti-inflammatory effects may be used for inflammatory disorders by examining alfalfa sprout ethyl acetate extract (ASEA). The cytokine profile and life span of BALB/c mice with acute inflammation after intra-peritoneal (ip) injection of 15 mg/kg BW lipopolysaccharide (LPS) were determined. The results showed that the life span of LPS-induced inflammatory mice were negatively correlated with serum levels of TNF-α, IL-6, and IL-1β at 9 hr after LPS-injection, which indicated that suppressing these cytokines in the late phase of inflammation may be beneficial for survival. The in vitro experiment then showed that ASEA significantly reduced IL-6 and IL-1β production and the NF-κB trans-activation activity of mitogen-stimulated RAW264.7 cells. To further evaluate the anti-inflammatory effects of ASEA in vivo, BALB/c mice were tube-fed with 25 mg ASEA/kg BW/day in 50 μl sunflower oil, while the control and PDTC (pyrrolidine dithiocarbamate, an anti-inflammatory agent) groups were tube-fed with 50 μl sunflower oil/day only. After one week of tube-feeding, the PDTC group was injected with 50 mg/kg BW PDTC and one hour later, all of the mice were injected with 15 mg/kg BW LPS. The results showed that the ASEA and PDTC groups had significantly lower serum TNF-α, IL-6, and IL-1β levels at 9 hr after LPS challenge, and significantly higher survival rates than the control group. This study suggests that ASEA supplementation can suppress the production of pro-inflammatory cytokines and alleviate acute inflammatory hazards.

Abstract
AIM OF THE STUDY Traditional Chinese medicine herbs (TCMHs) are used in medicines as well as in daily dietary supplements in Asia. In this study, we employed pNF-kappaB-Luc or pIFN-gamma-Luc and BALB/c mice peritoneal macrophages or splenocytes to investigate both the immune and inflammatory effects of six selected plant species. MATERIALS AND METHODS Specifically, we used ethyl acetate fractions of Astragalus membranaceus (Fisch.) Bunge var. mongholicus (Bunge) Hsiao (Fabaceae) (AM), Andrographis paniculata (Burm. f.) Nees (Acanthaceae) (AP), Angelica sinensis (Oliv.) Diels (Apiaceae) (AS), Eucommia ulmodes Oliv. (Eucommiaceae) leaves (EU leaves), Isatis indigotica Fort. (Brassicaceae) (II) and Morus alba L. (Moraceae) (MA). RESULTS We found that ethyl acetate fractions of AP, AS and MA significantly decreased NF-kappaB luciferase activity and also the secretion of NO and PGE(2) in LPS/IFN-gamma stimulated mouse peritoneal macrophages (p<0.05). In contrast, they did not affect IFN-gamma luciferase activity or IFN-gamma production in concanavalin A (Con A)-activated mouse splenocytes. Our results indicated that the anti-inflammatory properties of these plant extracts might be resulted from the inhibition of pro-inflammatory mediators (e.g., NO and PGE(2)), at least in part via suppression of a signaling pathway such as NF-kappaB. CONCLUSIONS Collectively, we have found that three potent bioactive TCMH species exerted significant NF-kappaB inhibitory activity and acted in a cell type dependent fashion.
