RESUMEN
JAK/STAT signaling pathways are closely associated with multiple biological processes involved in cell proliferation, apoptosis, inflammation, differentiation, immune response, and epigenetics. Abnormal activation of the STAT pathway can contribute to disease progressions under various conditions. Moreover, tofacitinib and baricitinib as the JAK/STAT inhibitors have been recently approved by the FDA for rheumatology disease treatment. Therefore, influences on the STAT signaling pathway have potential and perspective approaches for diverse diseases. Chinese herbs in traditional Chinese medicine (TCM), which are widespread throughout China, are the gold resources of China and have been extensively used for treating multiple diseases for thousands of years. However, Chinese herbs and herb formulas are characterized by complicated components, resulting in various targets and pathways in treating diseases, which limits their approval and applications. With the development of chemistry and pharmacology, active ingredients of TCM and herbs and underlying mechanisms have been further identified and confirmed by pharmacists and chemists, which improved, to some extent, awkward limitations, approval, and applications regarding TCM and herbs. In this review, we summarized various herbs, herb formulas, natural compounds, and phytochemicals isolated from herbs that have the potential for regulating multiple biological processes via modulation of the JAK/STAT signaling pathway based on the published work. Our study will provide support for revealing TCM, their active compounds that treat diseases, and the underlying mechanism, further improving the rapid spread of TCM to the world.
RESUMEN
Ulcerative colitis (UC) is a chronically relapsing inflammatory disease in the intestinal tract. Current unsatisfactory treatments prompt people to seek for alternative therapies and drug candidates. Cryptotanshinone (CTS), a diterpene quinoneextractedfromthe roots ofSalviamiltiorrhiza, has recently been shown to inhibit acute colitis by reducing pro-inflammatory mediators. However, whether CTS can protect against chronic UC and its effect on T lymphocytes remain unknown. In this study, CTS (20, 60 mg/kg) showed potent inhibitory activity against dextran sulfate sodium (DSS)-induced acute UC, as determined by weight loss, disease activity, colon length and histology. Similarly, in a model of DSS-induced chronic colitis, the administration of CTS prevented the disease progression with longer colon length, lower histological scores, and less expression of fibrosis-related collagen and α-smooth muscle actin in the colon. CTS also reduced the proportion of CD4+IL-17A+ Th17 cells in spleen and mesenteric lymph nodes of mice with acute or chronic colitis. However, CTS at 20 mg/kg had no effect on regulatory T cells (Tregs). In addition, CTS reduced the phosphorylation of signal transduction and transcription activator 3 (STAT3) in DSS-treated colon tissue. Further study showed that CTS concentration-dependently suppressed the differentiation of naïve CD4+ T cells into Th17 cells. CTS could not inhibit the activation and proliferation of T lymphocytes or attenuate the secretion of cytokines including IL-10, IL-2, IL-6 and IFN-γ, but could inhibit the production of IL-17A and TNF-α in Con A-stimulated splenocytes. CTS suppressed IL-6-induced phosphorylation and nuclear translocation of STAT3. In conclusion, our study demonstrated that CTS alleviated acute and chronic UC by suppressing STAT3 activation and Th17 cell differentiation, suggesting that it may be a promising candidate drug for the treatment of UC.

Inflammatory bowel disease (IBD) is a non-specific chronic intestinal inflammatory disease, often presenting with abdominal pain, diarrhea, bloody stool, anorexia, and body loss. It is difficult to cure completely and a promising treatment is urgently needed. Natural compounds can offer promising chemical agents for treatment of diseases. Polydatin is a natural ingredient extracted from the dried rhizome of Polygonum cuspidatum, which has anti-inflammatory, anti-tumor, and dementia protection activities. The purpose of this study was to evaluate the therapeutic effect of polydatin on IBD and explore its possible mechanism. We found that polydatin could effectively suppress the differentiation of Th17 cells in vitro, but had no effect on the differentiation of Treg cells. Polydatin significantly alleviated colitis induced by dextran sulfate sodium (DSS) and 2, 4, 6-trinitrobenzenesulfonic acid (TNBS) in mice, and dramatically decreased the proportion of Th17 cells in spleen and mesenteric lymph nodes. Mechanism investigations revealed that polydatin specifically inhibited signal transducer and activator of transcription 3 (STAT3) phosphorylation by directly binding to STAT3, leading to Th17 cell reduction and thereby alleviating colitis. These findings provide novel insights into the anti-colitis effect of polydatin, which may be a promising drug candidate for the treatment of IBD.

The present study is to establish a quantitative analysis of multi-components by single marker(QAMS) for determining contents of seven compositions in Alismatis Rhizoma, alismoxide, alisol C 23-acetate, alisol A, alismol, alisol B, alisol B 23-acetate and 11-deoxy-alisol B. Six relative correction factors(RCFs) of alismoxide, alisol C 23-acetate, alisol A, alismol, alisol B and 11-deoxy-alisol B were established in the UPLC method with alisol B 23-acetate as the internal standard, which was to calculate the mass fraction of each. The mass fraction of seven effective constituents in Alismatis Rhizoma was calculated by the external standard method(ESM) at the same time. Compared with the content results determined by the ESM and QAMS, the feasibility and accuracy of QAMS method were verified. Within the linear range, the RCFs of alismoxide, alisol C 23-acetate, alisol A, alismol, alisol B, 11-deoxy-alisol B were 0.946, 4.183, 0.915, 1.039, 0.923 and 1.244, respectively, with good repeatability in different experimental conditions. There was no significant difference between the QAMS method and ESM method. Then, QAMS method was applied to determination of the different degree Alismatis Rhizoma from different areas. As a result, the concentrations of 7 components have differences in different areas, but no significant differences in different grades. The QAMS method is feasible and accurate for the determination of the seven chemical compositions, and which can be used for quality control of Alismatis Rhizoma.

BACKGROUND: Allergic rhinitis (AR) is a chronic inflammatory disease of the nasal airways.Many therapies do not have immediate effects,even which have side-effects.However,the effects of Xingbi gel for the treatment of AR was investigated. OBJECTIVE: We investigated the effects of Xingbi gel on serum levels of leukotriene E4 (LTE4) and immunoglobulin E (IgE), as well as eosinophil counts in the nasal mucosa using a guinea pig model of allergic rhinitis (AR). METHODS: In addition to a healthy control group without AR, guinea pigs with AR were randomly divided into untreated AR control group, low-dose Xingbi gel (0.2483 g/mL) group, high-dose Xingbi gel (0.4966 g/mL) group, and budesonide group. RESULTS: Compared to the healthy controls, untreated AR guinea pigs had significantly higher ethology scores, serum LTE4 and IgE levels, and nasal mucosa eosinophil counts (p <0.01). Treatments with low-dose Xingbi gel, high-dose Xingbi gel, and budesonide significantly reduced the ethology scores, serum LTE4 and IgE levels, and nasal mucosa eosinophil counts as compared to untreated AR model guinea pigs (p <0.01). CONCLUSION: Xingbi gel alleviates AR in part through inhibiting LTE4 and IgE production and reducing eosinophilia in the nasal mucosa.

The aim of this study is to prepare self-microemulsifying drug delivery system (SMEDDS) of the mixture of paeonol (Pae) and borneol (Bor). Solubility test, ternary phase diagrams and simplex lattice method were employed to screen and optimize the formulation of the mixture of Pae and Bor-loaded SMEDDS. After formed into microemulsions, the particle diameter (PD) was determined and a TEM was employed to observe the microemulsions' morphology. The contents of Pae and Bor were determined by gas chromatography. As a result, while ethyl oleate (EO) as the oil phase, cremophor EL35 (EL35) as surfactant and Transcutol HP (HP) as cosurfactant, the range of the microemulsion on the ternary phase diagram was larger than other combinations. And at a ratio of 20:45:35, the microemulsions' PD was about 34 nm and the polydispersity index (PI) was about 0.2. There were 16% of Pae, 2% of Bor, 16% of EO, 37% of EL35 and 29% of HP in the prepared SMEDDS. The preparation process of the Pae and Bor-loaded SMEDDS based on Xingbi Fang is simple and feasible. This study provides a reference for the researches on the related traditional Chinese medicine and the related components.

OBJECTIVE: To study the toxicity features of high glucose on the endothelial cell cycle and the influence of Dan Gua-Fang, a Chinese herbal compound prescription, on the reproductive cycle of vascular endothelial cells cultivated under a high glucose condition; to reveal the partial mechanisms of Dan Gua-Fang in the prevention and treatment of endothelial injury caused by hyperglycemia in diabetes mellitus (DM); and offer a reference for dealing with the vascular complications of DM patients with long-term high blood glucose. METHODS: Based on the previous 3-(4,5)-dimethylthiahiazo (z-y1)-3-5-diphenytetrazoliumromide (MTT) experiment, under different medium concentrations of glucose and Dangua liquor, the endothelial cells of vein-304 (ECV-304) were divided into 6 groups as follows: standard culture group (Group A, 5.56 mmol/L glucose); 1/300 herb-standard group (Group B); high glucose culture group (Group C, 16.67 mmol/L glucose); 1/150 herb-high glucose group (Group D); 1/300 herb-high glucose group (Group E); and 1/600 herb-high glucose group (Group F). The cell cycle was assayed using flow cytometry after cells were cultivated for 36, 72 and 108 h, respectively. RESULTS: (1) The percentage of cells in the G0/G1 phase was significantly increased in Group C compared with that in Group A (P<0.05), while the percentage of S-phase (S%) cells in Group C was significantly reduced compared with Group A (P<0.05); the latter difference was dynamically related to the length of growing time of the endothelial cells in a high glucose environment. (2) The S% cells in Group A was decreased by 30.25% (from 40.23% to 28.06%) from 36 h to 72 h, and 12.33% (from 28.06% to 24.60%) from 72 h to 108 h; while in Group C, the corresponding decreases were 23.05% and 21.87%, respectively. The difference of S% cells between the two groups reached statistical significance at 108 h (P<0.05). (3) The percentage difference of cells in the G2/M phase between Group C and Group A was statistically significant at 72 h (P<0.01). (4) 1/300 Dan Gua-Fang completely reversed the harmful effect caused by 16.67 mmol/L high glucose on the cell cycle; moreover it did not disturb the cell cycle when the cell was cultivated in a glucose concentration of 5.56 mmol/L. CONCLUSIONS: High glucose produces an independent impact on the cell cycle. Persistent blocking of the cell cycle and its arrest at the G0/G1 phase are toxic effects of high glucose on the endothelial cell cycle. The corresponding variation of the arrest appears in the S phase. 1/300 Dan Gua-Fang completely eliminates the blockage of high glucose on the endothelial cell cycle.

OBJECTIVE: To study the effect of anticolchicine cytotoxicity of Dan Gua-Fang, a Chinesea Chinese), a Chinese herbal compound prescription on endothelial cells of vein (ECV304) cultivated in mediums of different glucose concentrations as well as the proliferation of those cells in the same conditions, in order to reveal the value of Dan Gua-Fang in preventing and treating endothelial damage caused by hyperglycemia in diabetes mellitus. METHODS: The research was designed as three stages. The growing state and morphological changes were observed when ECV304 were cultivated in the culture mediums, which have different glucose concentrations with or without Dan Gua-Fang and at the same time with or without colchicine. RESULTS: (1) Dan Gua-Fang at all concentrations reduced the floating cell population of ECV304 cultivated in hyperglycemia mediums. (2) Dan Gua-Fang at all concentrations and hyperglycemia both had a function of promoting "pseudopod-like" structure formation in cultivated ECV304, but the function was not superimposed in mediums containing both hyperglycemia and Dan Gua-Fang. (3) Colchicine reduced and even vanished the "pseudopod-like" structure of the endotheliocyte apparently cultivated in mediums of hyperglycemia or with Dan Gua-Fang. The "pseudopod-like" structure of the endotheliocyte emerged quickly in Dan Gua-Fang groups after colchicine was removed, but it was not the case in hyperglycemia only without Dan Gua-Fang groups. (4) Dan Gua-Fang reduced the mortality of cells cultivated in mediums containing colchicine. The cell revived to its normal state fast after colchicine was removed. CONCLUSION: Dan Gua-Fang has the functions of promoting the formation of cytoskeleton and fighting against colchicine cytotoxicity.

OBJECTIVE: To assess the anti-inflammatory effect of Aike Mixture (AKM) on rats with nonbacterial prostatitis (NBP). METHODS: Rat model of NBP was established by injection of Xiaozhiling Injection. The experimental rats were randomized into 7 groups: the three AKM groups (A1, A2 and A3), treated with high, middle and low dose of AKM respectively, the 2 positive control groups (C1 and C2), treated by Bazheng Mixture (BZM) and Qianliexian Decoction (QLXD) respectively, the model control group (Cm) and the sham-operative control group (Cso). The pathological changes in rats' prostate were observed by light microscope and transmission electron microscope. RESULTS: Significant differences in the number and structure of acini, mesenchyma, as well as the degrees of anti-fibroplasia and inflammatory cell infiltration were shown between the treated groups (A1, A2, A3, C1, C1, C2) and the untreated groups (Cm, Cso), with statistical significance (P < 0.05 or P < 0.01). However, the anti-fibroplasia and anti-inflammatory effects in A1 were better than that in the two positive control groups significantly (P < 0.05 or P < 0.01). CONCLUSIONS: AKM is a new TCM drug functioned for dispersing Gan-qi in treating NBP. It shows a better efficacy than that of BZM and QLXD, the two Chinese herbal medicines for clearing heat with remove dampness and activating blood circulation to remove stasis, respectively.

OBJECTIVE: To study the anti-inflammatory and analgesic actions of Aike Mixture (AKM). METHODS: A total of 100 male mice were randomly assigned into 5 groups: a normal control group, a drug control group (a hydrocortisone subgroup and an atropine subgroup), a high-dose AKM group, a mid-dose AKM group and a low-dose AKM group. Xylene was spread on the left ear of the experimental mice to induce inflammation, and 1% acetic acid solution injected into the abdominal cavity to produce pain so as to cause the body bend. Different doses of AKM were given and their actions observed. RESULTS: AKM had obvious anti-inflammatory effect on the xylene-induced ear tumefaction and inhibited the pain-caused body bend in the AKM groups, with significant difference from the normal control (P < 0.01). CONCLUSION: AKM has good anti-inflammatory and analgesic effects, which is of clinical significance in the treatment of chronic prostatitis.
