[PMID: 38318428 PMCID: PMC10839775 DOI: 10.1016/j.pacs.2024.100589] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 09/08/2023] [Revised: 01/09/2024] [Accepted: 01/17/2024] [Indexed: 02/07/2024]
Abstract
The endometrium microvessel system, responsible for supplying oxygen and nutrients to the embryo, holds significant importance in evaluating endometrial receptivity (ER). Visualizing this system directly can significantly enhance ER evaluation. Currently, clinical methods like Narrow-band hysteroscopy and Color Doppler ultrasound are commonly used for uterine blood vessel examination, but they have limitations in depth or resolution. Endoscopic Photoacoustic Imaging (PAE) has proven effective in visualizing microvessels in the digestive tract, while its adaptation to uterine imaging faces challenges due to the uterus's unique physiological characteristics. This paper for the first time that uses high-resolution PAE in vivo to capture a comprehensive network of endometrial microvessels non-invasively. Followed by continuous observation and quantitative analysis in the endometrial injury model, we further corroborated that PAE detection of endometrial microvessels stands as a valuable indicator for evaluating ER. The PAE system showcases its promising potential for integration into reproductive health assessments.

JOURNAL OF ETHNOPHARMACOLOGY 2023; 303:116002. [PMID: 36509253 DOI: 10.1016/j.jep.2022.116002] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/23/2022] [Revised: 11/22/2022] [Accepted: 11/25/2022] [Indexed: 06/17/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Albizia julibrissin Durazz is a well-known medicinal plant with the Chinese name Hehuan []. Hehuan bark and Hehuan flowers have long been recognized as traditional Chinese herbal medicine for treating anxiety, melancholy, insomnia, bruises, pulmonary abscess, fractures, carbuncle, amnesia, acute conjunctivitis, blurred vision, neonatal tetanus and stroke for thousands of years. They are recorded in Chinese Pharmacopoeia separately with different properties. Until now, new chemical constituents and pharmacological activities of Hehuan have been continuously studied and revealed. THE AIM OF THE REVIEW This review aims to provide a comprehensive summary of traditional applications, phytochemistry, pharmacology effects, and toxicology of Hehuan bark and Hehuan flowers, and give critical assessment and point out the promising direction for further research on Hehuan. MATERIAL AND METHODS A literature search was undertaken on Hehuan bark and Hehuan flowers by analyzing the information from scientific databases (SciFinder, Pubmed, Elsevier, Google Scholar, Web of Science, and Baidu Scholar). We also gathered the information of Hehuan from classic herbal literatures and conference papers on ethnopharmacology. RESULTS According to Chinese and English documents, the medicinal history of Hehuan in China can be traced back to ad 25. Meanwhile, its medicinal history as a kind of herbal medicine can also be found in other Asian countries. So far about 140 compounds have been isolated from Hehuan bark and Hehuan flowers, including triterpenoids, flavonoids, lignans, phenolic acids, alkaloids, etc. Among them, flavonoids mainly exist in Hehuan flowers, while Hehuan bark contains lignans and saponins. The composition differences between the barks and flowers of Hehuan account for the different effects and applications. Modern pharmacological studies have indicated that crude extracts and pure compounds of Hehuan flowers and Hehuan bark have multiple pharmacological activities, such as antineoplastic, immunomodulatory, anti-inflammatory, anxiolytic, antidepressant, metabolic regulation, anti-insomnia, neuroprotective, hepatoprotective, sedative, and anti-osteolytic activities. CONCLUSIONS Hehuan (Albizia julibrissin Durazz) is traditionally used to relieve depression, calm nerves, promote blood circulation and reduce swelling. Modern pharmacological studies have revealed that natural products from Hehuan bark and Hehuan flowers possess extensive pharmacological activities in treating cancer, enhancing immunity, regulating metabolism, improving mental state, etc. These properties make it great clinical application potential. Further research on natural pharmaceutical chemistry, pharmacology, toxicology, pharmacokinetics, and quality standards of Hehuan are still required to verify the efficacy and safety for future clinical applications.

Sesamin Attenuates VEGFA-Induced Angiogenesis via Inhibition of Src and FAK Signaling in Chick Chorioallantoic Membrane Model and Human Endothelial EA.hy926 Cells. Biomedicines 2023; 11:biomedicines11010188. [PMID: 36672695 PMCID: PMC9855418 DOI: 10.3390/biomedicines11010188] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/22/2022] [Revised: 01/06/2023] [Accepted: 01/07/2023] [Indexed: 01/13/2023] Open
Abstract
Sesamin, a major phytochemical in sesame seeds and oil, has been reported to have effects on physiological and pathological angiogenesis in several studies. Nevertheless, the underlying mechanisms of sesamin's effect on angiogenesis are not understood well enough. This study aimed to investigate its effect on both physiological and pathological angiogenesis using the in vivo chick chorioallantoic membrane (CAM) model and the in vitro human endothelial cell line, EA.hy926, model. Sesamin inhibited the VEGFA-induced pathological angiogenesis significantly, although no effect was seen on angiogenesis without induction. It reduced the formation of vascular branches in the VEGFA-treated CAMs and also the proliferation and migration of EA.hy926 endothelial cells induced by VEGFA. Sesamin impeded the VEGF-mediated activation of Src and FAK signaling proteins, which may be responsible for sesamin-mediated reduction of pathological angiogenesis. Moreover, the effect of sesamin on the expressions of angiogenesis-related genes was then investigated and it was found that both mRNA and protein expressions of Notch1, the key pathway in vascular development, induced by VEGFA, were significantly reduced by sesamin. Our results altogether suggested that sesamin, by inhibiting pathological angiogenesis, has the potential to be employed in the prevention or treatment of diseases with over-angiogenesis, such as cancers.

Abstract
Albizia julibrissin Durazz is one of the most common herbs used for depression and anxiety treatment, but its mechanism of action as an antidepressant or anxiolytic drug have not been fully understood. We previously isolated and identified one lignan glycoside compound from Albizia Julibrissin Durazz, (-)-syringaresinol-4-O-β-D-apiofuranosyl-(1→2)-β-D-glucopyranoside (SAG), that inhibited all three monoamine transporters with a mechanism of action different from that of the conventional antidepressants. In this study, we generated homology models for human dopamine transporter and human norepinephrine transporter, based on the X-ray structure of Drosophila dopamine transporter, and conducted the molecular docking of SAG to all three human monoamine transporters. Our computational results indicated that SAG binds to an allosteric site (S2) that has been demonstrated to be formed by an aromatic pocket positioned in the scaffold domain in the extracellular vestibule connected to the central site (S1) in these monoamine transporters. In addition, we demonstrated that SAG stabilizes a conformation of serotonin transporter with both the extracellular and cytoplasmic pathways closed. Furthermore, we performed mutagenesis of the residues in both the allosteric and orthosteric sites to biochemically validate SAG binding in all three monoamine transporters. Our results are consistent with the molecular docking calculation and support the association of SAG with the allosteric site. We expect that this herbal molecule could become a lead compound for the development of new therapeutic agents with a novel mechanism of action.

Wu YY, Li SY, Zhu HQ, Zhuang ZM, Shao M, Chen FL, Liu CS, Tang QF. Network pharmacology integrated with experimental validation reveals the regulatory mechanism of action of Hehuan Yin decoction in polycystic ovary syndrome with insulin resistance. JOURNAL OF ETHNOPHARMACOLOGY 2022; 289:115057. [PMID: 35121050 DOI: 10.1016/j.jep.2022.115057] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/09/2021] [Revised: 01/15/2022] [Accepted: 01/27/2022] [Indexed: 06/14/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Hehuan Yin decoction (HHY), first recorded in the Jingyue Quanshu (published in 1624 A.D.), is composed of Albizia julibrissin Durazz. and Ampelopsis japonica (Thunb.) Makino. AIM OF THE STUDY This study aimed to investigate the mechanism of action of HHY in treating polycystic ovary syndrome with insulin resistance (PCOS-IR). MATERIALS AND METHODS Network pharmacology and molecular docking were used to predict active compounds, potential targets, and pathways for PCOS-IR treatment using HHY. Female Sprague-Dawley rats were administered letrozole (1 mg/kg) with a high-fat diet to establish a PCOS-IR model. Thereafter, symptoms, ovarian pathology, serum insulin resistance, and sex hormone levels were determined. Western blotting was used to determine the levels of PI3Kp85α, AKT, phospho (p)-AKT, and GSK3β in the ovaries of rats. RESULTS Network pharmacology revealed 58 components in HHY and 182 potential targets that were shared between HHY and PCOS-IR. HHY could potentially treat PCOS-IR via the insulin resistance, PI3K/AKT, HIF-1, and steroid hormone biosynthesis pathways. Molecular docking revealed that PI3K, AKT1, GSK3β, IRS1, and EGFR had high affinities to HHY compounds. In the PCOS-IR rats, HHY significantly normalised the symptoms and ovarian pathology, increased follicle-stimulating hormone (FSH) and oestradiol levels in the serum, and decreased the levels of fasting plasma glucose and fasting insulin, as well as the insulin resistance index. HHY also decreased the luteinising hormone (LH) and testosterone levels and the LH/FSH ratio in the PCOS-IR rats and increased the levels of PI3K, p-AKT, and GSK3β in ovary tissue, which indicated the activation of the PI3K/AKT pathway. CONCLUSIONS HHY can improve PCOS-IR symptoms via multiple pharmacological pathways and may be a potential alternative therapy for the treatment of PCOS-IR.

J Food Biochem 2021; 45:e13514. [PMID: 33569819 DOI: 10.1111/jfbc.13514] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/04/2020] [Revised: 09/05/2020] [Accepted: 09/22/2020] [Indexed: 01/01/2023]
Abstract
A response surface method was used to optimize the extraction of polysaccharides from Leucocalocybe mongolica. Moreover, the preliminary structural characteristics and antitumor activity of L. mongolica polysaccharide (LMP) were investigated. The results showed that the optimized extraction technological parameters for LMP were 93°C extraction temperature, 5 hr extraction time, and 30 ml/g liquid-to-solid ratio. The LMP content extracted under the optimal conditions was 6.64%. LC-MS/MS results indicated that LMP is a neutral polysaccharide composed of d-fructose, d-mannose, dextrose anhydrate, d-xylose, trehalose, and galactose. The tumor inhibition rate was significantly improved by LMP treatment. LMP had minimal toxicity based on the significant decrease in AST and BUN levels; VEGF protein levels were also significantly decreased. In contrast, the levels of IFN-γ, IL-2, IL-6, and TNF-α were improved. The results of ELISA, H&E staining, TUNEL assay, immunohistochemistry, and western blotting indicated that the LMP exhibited antitumor activity in vivo by promoting apoptosis, mediating inflammatory responses, and inhibiting angiogenesis. PRACTICAL APPLICATIONS: As one of the main bioactive components, fungal polysaccharide has always been a hot research topic. Fungal polysaccharides are carbohydrate polymers composed of monosaccharide units bound together by glycosidic linkages, which have been found to be involved in many biological processes. In this research, the LMP structure was analyzed, and the immunohistochemical and western blot analysis confirmed that, LMP could effectively reduce the generation of tumor angiogenesis, promote apoptosis of tumor cell sand inhibit tumor growth. The results of this study can effectively provide a basis for clinical research and development of antitumor drugs, and lay a foundation for the study of the antitumor effects of wild edible and medicinal fungi.

Abstract
Multiterritory perforator flap is an important plastic surgery technique, yet its efficacy can be limited by partial necrosis at the choke Ⅱ zone. Butylphthalide (NBP) has been used for many diseases but has not been studied in the multiterritory perforator flap. With the effect of NBP, we observed increasing in capillary density, inhibition of autophagy and oxidative stress, and a reduction in apoptosis of cells, all consistent with increased flap survival. However, the protective effect of NBP on multiterritory perforator flap was lost following administration of the autophagy agonist rapamycin (Rap). Through the above results, we assumed that NBP promotes flap survival by inhibiting autophagy. Thus, this study has found a new pharmacological effect of NBP on the multiterritory perforator by inhibiting autophagy to prevent distal postoperative necrosis and exert effects on angiogenesis, oxidative stress, and apoptosis within the flap.

ETHNOPHARMACOLOGICAL RELEVANCE The genus Albizia (Leguminosae) comprises about 150 species and some species have been used for the treatment of rheumatism, stomachache, cough, diarrhea, and wounds in traditional and local medicine. The aim of the review: This review article documents and critically assesses the current status of the traditional uses, phytochemistry, pharmacology, and toxicology of the Albizia species. MATERIALS AND METHODS All provided literatures on the Albizia species were searched using the electronic databases (e.g. Web of Science, Elsevier, Springer, PubMed, ACS, CNKI, Google Scholar, and Baidu Scholar), books, and theses with keywords of 'Albizia' and 'Albizzia'. RESULTS Albizia species have been used for melancholia, insomnia, wounds, fever, abscesses, diabetes, headache, stomachache, diarrhea, cough, rheumatism, snake bite, malaria, and parasitic infection in traditional and local medicine. These plants mainly contain triterpenoid saponins, flavonoids, lignanoids, alkaloids, phenolic glycosides, etc. Albizia species have been demonstrated to possess various pharmacological activities. Among them, the antidiabetic, anti-inflammatory, antifertility, antianxiety, antidepressant, and anti-fever properties are consistent with the traditional and local applications of the Albizia species. CONCLUSIONS The traditional and local uses of Albizia species have been partially demonstrated by the pharmacological investigation. However, some traditional applications have not been assessed scientifically due to incomplete methodologies and ambiguous findings. Moreover, no clinical evidences support the health benefits of these plants. The systematic and comprehensive preclinical studies and clinical trials are still required to verify the pharmacological activities, clinical efficacy, and safety of Albizia species.

J Anim Physiol Anim Nutr (Berl) 2020; 104:637-644. [PMID: 31898833 DOI: 10.1111/jpn.13302] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/27/2019] [Revised: 10/14/2019] [Accepted: 12/06/2019] [Indexed: 02/02/2023]
Abstract
The present study aimed to evaluate the potential therapeutic effects of Anemoside B4 (AB4), Panax notoginseng saponins (PNS), Notoginsenoside R1 (SR1), Saikosaponin A (SSA) and Saikosaponin D (SSD) on piglets infected with porcine reproductive and respiratory syndrome virus (PRRSV). A total of 132 completely healthy piglets were randomly divided into 22 groups consisting of six animals each. Control piglets were intramuscularly injected with 2 ml of PRRSV (NJGC strain) solution containing 106 TCID50 virus/ml. For low-, middle- and high-dose saponin treatment groups, the piglets were initially administrated with the same volume of PRRSV solution, followed by intraperitoneal injection with AB4, PNS, SR1, SSA or SSD at 1, 5 or 10 mg/kg b.w. on day 3. The piglets in drug control group were intraperitoneally injected with 10 mg/kg b.w. of each saponin without prior PRRS challenge, while those in blank control group were injected with the same amount of normal saline. The results indicated that all the five saponin components could decrease the incidence and severity of PRRSV-induced immunopathological damages, including the elevated body temperature, weight loss, anaemia and internal inflammation. Moreover, the saponin components could enhance protein absorption and immune responses. Taken together, this study reveals that the saponin components are effective against PRRSV infection and strengthen the immune system and thus may serve as potential antiviral therapeutic agents.

Abstract
Objectives: Herbs are frequently and concurrently used with prescribed drugs by patients worldwide. While clinical trials have found some herbs to be as useful as standard psychiatric drugs, most clinicians are unaware of their pharmacological mechanisms.Methods: We searched English language and other language literature with English abstracts listed in PubMed website, supplemented by additional through Google Scholar's free academic paper abstract website for publications on herbs, focussing on their clinical use in mental disorders, their neurobiology and their pharmacology.Results: A major reason for herbs remaining outside of mainstream psychiatry is that the terminology and concepts in herbal medicine are not familiar to psychiatrists in general. Many publications regarding the use of herbal medicine for psychiatric disorders are deficient in details regarding diagnosis, criteria for response and the neurobiology details compared with publications on standard psychotropic drugs. Nomenclature for herbal medicine is usually confusing and is not conducive to an easy understanding of their mode of action in psychiatric disorders.Conclusions: The recent neuroscience-based nomenclature (NbN) for psychotropics methodology would be a logical application to herbal medicine in facilitating a better understanding of the use of herbal medicine in psychiatry.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Albiziae Cortex (AC) is a widely used traditional medicine in China. It is possess various properties to treat insomnia, traumatic injuries, diuresis, sthenia, and confusion. Total saponins of Albiziae Cortex (TSAC) are the most abundant bioactive components of AC, which were reported to show significant anti-tumor effects in vivo and in vitro. But the underlying mechanism of TSAC remained to be revealed. AIM OF STUDY In this study, we investigated the anti-hepatoma carcinoma effects and the potential mechanism of TSAC in vivo and in vitro. MATERIALS AND METHODS We first purified TSAC from crude extracts and characterized the major bioactive compounds by high performance liquid chromatography (HPLC). Effects of TSAC on viability of various hepatoma carcinoma cell lines were measured by MTT. Inhibition on cell proliferation was analysed using colony formation assay. Cell cycle distribution was revealed by flow cytometry. The apoptotic cells were observed by Hoechst 33258 staining and acridine orange (AO)/ethidium bromide (EB) double staining. Microstructures of apoptotic cells were examined by Transmission electron microscopy (TEM). The mitochondrial membrane potential were determined by JC-1 staining. Western blot was used to investigate the effects of TSAC on apoptosis-related proteins, B-cell lymphoma-2 (Bcl-2) and Bcl-2-associated X protein (Bax), and S-phase related protein cyclin A, cyclin E and cyclin-dependent kinases 2 (CDK2). Effects on tumor growth was assessed by H22-bearing ICR mice. RESULTS TSAC significantly decreased the hepatoma carcinoma cell viability and inhibited HepG2 cell colony formation in a concentration-dependent manner. We also found that TSAC inhibited HepG2 cell growth via induction of S phase arrest. Further study showed that TSAC significantly down-regulated the expressions of cyclin A, cyclin E and CDK2 in HepG2 cells. Meanwhile, TSAC could effectively induce mitochondria-dependent caspase apoptosis pathway activation. Furthermore, TSAC increased the expression of pro-apoptotic protein Bax and decreased the expression of anti-apoptotic protein Bcl-2. In vivo assay showed that the anti-tumor effects of TSAC were significantly augmented without increasing toxicity in H22-bearing ICR mice. CONCLUSION TSAC could inhibit cell proliferation through inducing S phase arrest and activate cell apoptosis via mitochondria-dependent apoptosis pathway. Therefore, TSAC could be a promising agent in clinical trials for anti-hepatoma carcinoma treatment.

Abstract
Bearing in mind the doctrine of tumor angiogenesis hypothesized by Folkman
several decades ago, the fundamental strategy for alleviating numerous cancer
indications may be the strengthening application of notable antiangiogenic
therapies to inhibit metastasis-related tumor growth. Under physiological
conditions, vascular sprouting is a relatively infrequent event unless when
specifically stimulated by pathogenic factors that contribute to the
accumulation of angiogenic activators such as the vascular endothelial growth
factor (VEGF) family and basic fibroblast growth factor (bFGF). Since VEGFs have
been identified as the principal cytokine to initiate angiogenesis in tumor
growth, synthetic VEGF-targeting medicines containing bevacizumab and sorafenib
have been extensively used, but prominent side effects have concomitantly
emerged. Traditional Chinese medicines (TCM)–derived agents with distinctive
safety profiles have shown their multitarget curative potential by impairing
angiogenic stimulatory signaling pathways directly or eliciting synergistically
therapeutic effects with anti-angiogenic drugs mainly targeting VEGF-dependent
pathways. This review aims to summarize (a) the up-to-date
understanding of the role of VEGF/VEGFR in correlation with proangiogenic
mechanisms in various tissues and cells; (b) the elaboration of
antitumor angiogenesis mechanisms of 4 representative TCMs, including
Salvia miltiorrhiza, Curcuma longa, ginsenosides, and
Scutellaria baicalensis; and (c)
circumstantial clarification of TCM-driven therapeutic actions of suppressing
tumor angiogenesis by targeting VEGF/VEGFRs pathway in recent years, based on
network pharmacology.

Abstract
Objective Vascular endothelial growth factor (VEGF) and VEGF receptors (VEGFRs) play
important roles in angiogenesis of different developmental mechanisms such as wound
healing, embryogenesis and diseases, including different types of cancer. VEGFR2 is
associated with cell proliferation, migration, and vascular permeability of endothelial cells.
Blocking VEGF and its receptors is suggested as a therapeutic approach to prevent tumor
growth. In this study, we aim to block VEGF signaling via small interfering RNA (siRNA)
inhibition of VEGFR2.
Materials and Methods In this experimental study, we used the RNA interference (RNAi)
mechanism to suppress expression of the VEGFR2 gene. We conducted the 3-(4,5-di-
methylthiazol-2-yl)-2,5-diphenyl-tetrazolium bromide (MTT) assay, real-time polymerase
chain reaction (PCR), Western blot, and flow cytometry analyses of VEGFR2 expression.
Results Real-time PCR and Western blot results showed that VEGFR2 expression
significantly downregulated. This suppression was followed by inhibition of cell prolifera-
tion, reduction of viability, and induction of apoptosis in the cancer cells.
Conclusion These findings suggest that VEGFR2 has a role in cell proliferation and
tumor growth. Accordingly, it is suggested that VEGFR2 can be a therapeutic target
for controlling tumor growth and proliferation.

Abstract
Although previous studies confirmed that steaming and the fermentation process could significantly improve the cognitive-enhancement and neuroprotective effects of Codonopsis lanceolata, the anti-tumor efficacy of steamed C. lanceolata (SCL) and what mechanisms are involved remain largely unknown. The present study was designed to evaluate the anti-tumor effect in vivo of SCL in H22 tumor-bearing mice. The results clearly indicated that SCL could not only inhibit the tumor growth, but also prolong the survival time of H22 tumor-bearing mice. Besides, the serum levels of cytokines, such as interferon gamma (IFN-γ), tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6) and interleukin-2 (IL-2), were enhanced by SCL administration. The observations of Hoechst 33258 staining demonstrated that SCL was able to induce tumor cell apoptosis. Finally, immunohistochemical analysis revealed that SCL treatment significantly increased Bax expression and decreased Bcl-2 and vascular endothelial growth factor (VEGF) expression of H22 tumor tissues in a dose-dependent manner. Moreover, LC/MS analysis of SCL indicated that it mainly contained lobetyolin and six saponins. Taken all together, the findings in the present study clearly demonstrated that SCL inhibited the H22 tumor growth in vivo at least partly via improving the immune functions, inducing apoptosis and inhibiting angiogenesis.
