Abstract
Leonurus sibiricus L. has great ethnobotanical and ethnomedicinal significance. This study aimed to assess the antioxidant and anti-inflammatory properties of Leonurus sibiricus L. transgenic roots extracts transformed by Rhizobium rhizogenes, with and without the AtPAP1 transcriptional factor. The study determined the total phenolic and flavonoid contents, as well as in vitro antioxidant assays, including hydrogen peroxide and nitric oxide scavenging activity. In addition, in silico computational studies and molecular docking were conducted to evaluate the antioxidant and anti-inflammatory potential of the identified compounds. The ligands were docked to NADPH oxidase, cyclooxygenase 2,5-lipoxygenase, inducible nitric synthase and xanthine oxidase: enzymes involved in the inflammatory process. The total phenolic and flavonoid contents ranged from 85.3 ± 0.35 to 57.4 ± 0.15 mg/g GAE/g and 25.6 ± 0.42 to 18.2 ± 0.44 mg/g QUE/g in hairy root extracts with and without AtPAP1, respectively. H2O2 scavenging activity (IC50) was found to be 29.3 µg/mL (with AtPAP1) and 37.5 µg/mL (without AtPAP1 transcriptional factor), and NO scavenging activity (IC50) was 48.0 µg/mL (with AtPAP1) and 68.8 µg/mL (without AtPAP1 transcriptional factor). Leonurus sibiricus L. transformed root extracts, both with and without AtPAP1, are a source of phytochemicals belonging to different classes of molecules, such as flavonoids (catechin and rutin), phenolic compounds (caffeic acid, coumaric acid, chlorogenic acid, ferulic acid) and phenylpropanoid (verbascoside). Among the radicals formed after H removal from the different -OH positions, the lowest bond dissociation enthalpy was observed for rutin (4'-OH). Rutin was found to bind with cyclooxygenase 2, inducible nitric synthases and xanthine oxidase, whereas chlorogenic acid demonstrated optimal binding with 5-lipoxygenase. Therefore, it appears that the Leonurus sibiricus L. transformed root extract, both with and without the AtPAP1 transcriptional factor, may serve as a potential source of active components with antioxidant and anti-inflammatory potential; however, the extract containing AtPAP1 demonstrates superior activities. These properties could be beneficial for human health.

Abstract
BACKGROUND Unintended pregnancy is a problem that women encounter throughout their reproductive age. Excessive and prolonged uterine bleeding is one of the most common and critical adverse reactions of induced abortion, for it increases the risk of anemia and intrauterine infection. To provide reliable clinical evidence, we performed a protocol for systematic review and meta-analysis to evaluate the hemostatic effect of motherwort in postabortion. METHODS This review protocol has been registered in the international prospective register of systematic reviews. The statement of Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols will be used as guidelines for reporting present review protocol. Original clinical randomized controlled trials assessing the beneficial effects and safety of motherwort on induced abortion will be included. Databases searched include China National Knowledge Infrastructure, Chinese Scientific Journals Database, Wanfang Database, China Biological Medicine Database, PubMed, and EMBASE Database and Cochrane Central Register of Controlled Trials. Cochrane collaboration tool is used to assess the risk of bias of included randomized controlled trials. All calculations are carried out with Stata 11.0 (The Cochrane Collaboration, Oxford, United Kingdom). RESULTS This systematic review and meta-analysis will provide a detailed summary of the current evidence related to the efficacy of motherwort injection preventing postabortion hemorrhage after induced abortion. CONCLUSION This evidence will be useful to practitioners, patients, and health policy-makers regarding the use of motherwort injection in induced abortion.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Leonurus japonicus Houtt., also known as motherwort, is a traditional Chinese medicine that was first identified in Shennong Bencao Jing, the first and essential pharmacy monograph in China. L. japonicus has been regarded as a good gynecological medicine since ancient times. It has been widely used in clinical settings for treatment of gynecological diseases and postnatal rehabilitation with good efficacy and low adverse effects. AIM OF THE STUDY The main purpose of this study was to determine the angiogenic and wound healing effects of total alkaloid fraction from L. japonicus Houtt. (TALH) in vivo and in vitro. In addition, the main bioactive components of total alkaloids were to be identified and analyzed in this study. MATERIALS AND METHODS First, the UHPLC/Q-TOF-MS method was used to identify and quantify the major components in the TALH extract. The wound healing activity was evaluated in vivo using a rat full-thickness cutaneous wound model. Histological study of wound healing in rat model was performed via immunohistochemistry and immunofluorescence. Cell proliferation was determined by MTT assay. Wound healing and transwell assays were used for detection of cell migration. The effect on tube formation was determined by tube formation assay in HUVECs. Western blot and RT-PCR were used to detect the expressions of relative proteins and genes respectively. Knock-down of SRC by siRNA was done to verify the crucial role of SRC in promotion of angiogenesis induced by TALH. RESULTS Seven characteristic peaks were recognized in the UHPLC/Q-TOF-MS spectrum, while four of the main components were quantified. The wound model in rats showed that treatment of TALH promoted wound healing by stimulating cellular proliferation and collagen deposition. In vitro experiments showed that co-treatment of TALH and VEGF increased cell proliferation, migration and tube formation in HUVECs. Mechanistic studies suggested that the co-treatment increased gene expressions of SRC, MEK1/2 and ERK1/2, as well as the phosphorylation levels of these proteins. Furthermore, the effect of co-treatment was attenuated after SRC knockdown, suggesting that SRC plays an important role in angiogenesis and wound healing induced by TALH and VEGF co-treatment. CONCLUSION Our results showed that TALH was one of the main active components of L. japonicus that promoted angiogenesis and wound healing by regulating the SRC/MEK/ERK pathway. Our study provided scientific basis for better clinical application of L. japonicas.

Abstract
BACKGROUND No well-designed and systematic evaluation of the efficacy and safety of leonurus japonicus injection (LJI) in combination with carboprost tromethamine has been found. Therefore, we undertook a meta-analysis to assess the efficacy and safety of carboprost tromethamine combined with LJI for the prevention of postpartum hemorrhage in high-risk pregnant women to provide new evidence-based medical evidence for clinical treatment. METHODS This systematic review and meta-analysis would be performed according to Preferred Reporting Items for Systematic reviews and Meta-Analyses guidelines. The following databases including EMBASE, MEDICINE, Wanfang, China National Knowledge Infrastructure database, and Cochrane central controlled trial registries were searched by 2 reviewers from inception to July 2021. Mesh and keyword search terms were "motherwort," "Yimucao," "leonurus japonicas," "carboprost tromethamine," and "postpartum hemorrhage." Any cohort studies that assessed the efficacy and safety of carboprost tromethamine combined with LJI for the prevention of postpartum hemorrhage would be included. P < .05 was set as the level of significance. RESULTS The review would add to the existing literature by showing compelling evidence and improved guidance in clinic settings.

Abstract
INTRODUCTION Dragendorff's reagent has low sensitivity and non-specificity for some alkaloids. A new alkaloid derivatisation reagent has been developed and optimised by using a Box-Behnken design method. This new reagent is applicable for structurally diverse natural alkaloids, and is proposed as a universal alkaloid staining reagent. OBJECTIVE To establish an efficient and sensitive thin-layer chromatography (TLC) identification method for Leonuri Herba and Leonuri Fructus to characterise their differences and similarities. METHOD Three key components (bismuth subnitrate, potassium iodide and iodine) in the derivatisation reaction were re-constructed and optimised using a response surface method. Different inorganic acids, essential additives of the staining reaction, were compared by a single-factor experiment design. RESULTS This newly optimised reagent for alkaloids reported in this study, named the enhanced Dragendorff-Wagner's reagent, is composed of 0.82% bismuth subnitrate, 11.1% potassium iodide and 0.76% iodine in 38% phosphoric acid solution. Validation results indicate that the TLC spot of stachydrine stained with the enhanced Dragendorff-Wagner's reagent had a limit of detection of 2.0 μg, good intra- and inter-plate, and intra- and intra-day precisions with relative standard devition values less than 5.0%, and stability over 90 min. CONCLUSION This enhanced Dragendorff-Wagner's reagent was applied for TLC identification of 16 reference alkaloids representing 11 structural skeletons, and two closely related herbs (Leonuri Herba and Leonuri Fructus). This newly enhanced Dragendorff-Wagner's reagent is a universal, effective, and sensitive staining reagent for alkaloids.

Abstract
Two sesquiterpene synthases were identified through comparative transcriptome analysis of Leonurus sibiricus. LsSqTPS2 could produce high titer of δ-cadinene in vivo which suggests the terpene specificity of L. sibiricus. Leonurus sibiricus L., a medicinal herb, is widely used in China due to its pharmacological activities. Cadinene type sesquiterpenes, one of major bioactive components mainly present in aerial parts of L. sibiricus, showed antibacterial, anti-inflammatory, antioxidant and antiproliferative properties. However, there is no report about the sesquiterpene biosynthesis in L. sibiricus. This study identified L. sibiricus sesquiterpene synthases (LsSqTPSs) through comparative transcriptome analysis of L. sibiricus leaf and root samples using the BGISEQ-500 sequencing technique. A total of 83,244 unigenes were obtained with an average length of 1025 bp. Among them, 50,356 unigenes (60.49%) acquired annotations according to the BLAST searching results. A total of 68 differentially expressed genes (DEGs) were potentially involved in the sesquiterpene biosynthesis. Furthermore, four candidate DEGs encoding LsSqTPSs were characterized. The enzymatic characterization in engineered yeast showed that LsSqTPS1 produced α-farnesene as the single product and LsSqTPS2 mainly produced 76.23 mg/L of δ-cadinene, which constituted the major component of L. sibiricus leaf essential oil. This work contributes to the investigation of sesquiterpene biosynthesis in L. sibiricus.

Abstract
OBJECTIVE Current global trends on natural therapeutics suggest an increasing market interest toward the use and discovery of new plant-derived therapeutic compounds, often referred to as traditional medicine (TM). The Cannabis industry is currently one such focal area receiving attention, owing to the occurrence of phytocannabinoids (pCBs) which have shown promise in health-promotion and disease prevention. However, the occurrence of pCBs in other plant species are often overlooked and rarely studied. Leonotis leonurus (L.) R. Br. is endemic to South Africa with a rich history of use in TM practices amongst indigenous people and, has been recorded to induce mild psychoactive effects akin to Cannabis. While the leaves have been well-reported to contain therapeutic phytochemicals, little information exists on the flowers. Consequently, as part of a larger research venture, we targeted the flowers of L. leonurus for the identification of potential pCB or pCB-like compounds. RESULTS Flower extracts were separated and analyzed using high performance thin layer chromatography (HPTLC). A single pCB candidate was isolated from HPTLC plates and, using liquid chromatography coupled to tandem mass spectrometry (LC-MS/MS), we could successfully group this compound as a fatty amide and tentatively identified as 7,10,13,16-Docosatetraenoylethanolamine (adrenoyl-EA), a known bioactive compound.

Abstract
Seven undescribed labdane diterpenoids, japonicones A-G, were isolated from the aerial parts of Leonurus japonicus Houtt. Japonicones C-G contained two keto carbonyl groups in their structures attached to C-3 and C-7, which are rare for labdane diterpenoids. The structures and absolute configurations of japonicones A-G were established by means of spectroscopic analyses (HRESIMS, 1D and 2D NMR, and ECD). Their anti-inflammatory activities were evaluated by measuring their inhibitory effects on PGE2 production in LPS-stimulated RAW264.7 macrophages. Japonicones A-D and G showed inhibition of PGE2 production with IC50 values in the range of 8.62-30.71 μM (the positive control paracetamol showed an IC50 = 5.79 μM).

Ten highly oxygenated diterpenoids (nine undescribed ones) were isolated from the aerial parts of Leonurus japonicus Houtt. 14,15-Dinor-labd-5,8-dien-3,13-dione was a 14,15-dinor-labdane diterpenoid possessing a C18 skeleton. 7β,9α-Dihydroxy-6-oxo-labd-13-en-15,16-amide represented a rare example of labdane diterpenoid featuring an α,β-unsaturated-γ-lactam moiety. The structures of all compounds were elucidated using spectroscopic data analyses and comparisons. The effects of these obtained compounds on nitric oxide (NO) production induced by lipopolysaccharide (LPS) in RAW 264.7 cells were evaluated.(10R*,13R*,15R*)-15,16-Epoxy-6,13-dihydroxy-15-methoxy-labda-5,8-dien-7-one inhibited NO production with an IC50 value of 40.1 μM.

Abstract
OBJECTIVE To assess the impact of motherwort injection alone or combined with oxytocin for preventing postpartum hemorrhage in pregnant women with caesarean section. METHODS A systematic review and meta-analysis of randomized trials were performed. PubMed, EMbase, The Cochrane Central Register of Controlled Trials (CENTRAL), Chinese database Sino-Med, Chinese National Knowledge Infrastructure Database (CNKI), VIP Chinese Science and Technique Journals Database, WanFang, and ClinicalTrials.gov were searched. Randomized controlled trials (RCTs) that compared motherwort injection alone or motherwort injection combined with oxytocin in pregnant women receiving cesarean section were included. Paired reviewers independently screened abstracts and full texts for eligibility, assessed risk of bias, and extracted data. We performed random-effects meta-analyses of RCTs along with a limited number of prespecified subgroup hypotheses, and sensitivity analyses were carried out with other statistical approaches. RESULTS Forty-six RCTs (n = 7359) proved eligible. Compared with oxytocin, both motherwort injection and motherwort injection combined with oxytocin had a significantly lower blood loss within 2 hours (MD = -21.81, 95% CI -37.05 to -6.58 and MD = -53.04, 95% CI -61.68 to -44.39); lower blood loss within 24 hours (MD = -25.44, 95% CI -39.38 to -11.51 and MD = -67.81, 95% CI -78.02 to -57.60); and lower the risk of adverse events (ORPeto 0.40, 95% CI 0.16 to 0.96 and ORPeto 0.50, 95% CI 0.35 to 0.71). Motherwort injection combined with oxytocin also decreased the risk of postpartum hemorrhage (OR 0.22, 95% CI 0.14 to 0.35.) CONCLUSIONS: In pregnant women with cesarean section, motherwort injection suggests an obvious benefit and less adverse event.

Abstract
The physical, chemical, and microbiological stability of a compounded oral solution with the active ingredients herbal tinctures of valerian and motherwort with sedative action for pediatric treatment was studied. Evaluations for physical, chemical, and microbiological stability were performed initially and throughout the storage period. Physical stability of the oral solution was assessed by coloration, clarity, and pH of the solution. The physical appearance of the oral solution did not change throughout the study period. The chemical stability of the oral solution was evaluated by means of a stability-indicating high-performance thin-layer chromatography analytical technique, identification tests, and assay method of sodium bromide. The microbiological stability of the oral solution was investigated by using the European Pharmacopoeia method using the acceptance criteria for nonsterile aqueous preparations for oral use. It was found that the compounded oral solution was stable for at least 21 days at 25°C ± 2°C/60% RH and 5°C ± 3°C, when protected from light.

Abstract
Bacterial canker caused by Pseudomonas syringae pv. Actinidiae is one of the most important diseases of kiwifruit (Actinidia chinensis) and leads to considerable yield losses. In order to obtain transgenic plants with resistance for 'Red Sun' kiwifruit to canker disease, a non-specific lipid transfer protein-like antimicrobial protein gene (LJAMP2) from motherwort (Leonurus japonicus) was introduced into 'Red Sun' kiwifruit through Agrobacterium-mediated transformation. After two days of co-cultivation with A. tumefaciens strain LBA4404 harboring 35S:LJAMP2, the transformed explants were transferred to the selection medium containing 25 mg/L kanamycin+3.0 mg/L BA+1.0 mg/L NAA. The regeneration efficiency of kanamycin-resistant shoots reached to 85%. All (100%) of kanamycin-resistant shoots rooted on half-strength MS medium supplemented with 0.8 mg/L IBA and a total of 40 regenerated plantlets were obtained. PCR and histochemical GUS activity analysis show that 23 of 40 lines (57.50%) were positive, suggesting that the LJAMP2 gene was integrated into the genome of 'Red Sun' kiwifruit. Taken together, we established an efficient genetic transformation method for 'Red Sun' kiwifruit using A. tumefaciens and the transformation frequency reached 5.11%. This protocol will be useful for the genetic breeding of 'Red Sun' kiwifruit for improvement of disease resistance.

Abstract
Complementary and alternative medical (CAM) therapies are commonly used by patients for the treatment of medical conditions spanning the full spectrum of severity and chronicity. The use of alternative remedies, both herbal and others, for conditions lacking effective medical treatment, is on the increase. Included within this categorization, arrhythmic disease-absent effective catheter-based therapy or with medical therapy limited by the toxicities of contemporary antiarrhythmic agents is frequently managed by patients with CAM therapies without their practitioner's knowledge and in the face of potential herb-drug toxicities. This study reviews 9 CAM therapies: 7 individual herbal therapies along with acupuncture and yoga that have been studied and reported as having an antiarrhythmic effect. The primary focuses are the proposed antiarrhythmic mechanism of each CAM agent along with interactions between the CAM therapies and commonly prescribed medical therapy for arrhythmia patients. We stress persistent vigilance on the part of the provider in discussing the use of herbal or other CAM agents within the arrhythmia population.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Traditional Mongolian medicine (TMM) uses preparations from herbs as one form of medication for the treatment of a diversity of diseases including diabetes mellitus (DM). We evaluated the effect of extracts from the plant Leonurus sibiricus L. (LS), used in TMM to treat typical symptoms of type 2 DM, on insulin secretion, electrophysiological properties, intracellular calcium concentration and cell proliferation of INS-1E insulinoma cells under standard cell culture conditions (SCC; 11.1mM glucose). MATERIALS AND METHODS Insulin secretion was measured by ELISA, electrical properties were assessed by whole cell patch clamping, intracellular calcium concentration (Cai) by Fluo-4 time lapse imaging, insulin receptor expression was verified by RT-PCR and cell proliferation assessed by CellTiter-Glo® cell viability assay. RESULTS Insulin released from INS-1E cells into the culture medium over 24h was significantly increased in presence of 500 mg/L aqueous LS extract (LS OWE) as well as methanolic LS extract (LS MeOH/H2O) but not in the presence of the butanol-soluble extract (LS MeOH/BuOH). Acute application of LS OWE resulted in a depolarization of the cell membrane potential paralleled by an initial increase and subsequent decline and silencing of action potential frequency, by KATP channel inhibition, persisting depolarization and an increase in Cai. The electrophysiological effects were comparable to those of 100 μM tolbutamide, which, however failed to elevate insulin secretion under SCC. Furthermore all LS extracts stimulated INS-1E cell proliferation. CONCLUSIONS The finding that extracts from Leonurus sibiricus L. enhance insulin secretion and/or foster cell proliferation may provide possible explanations for the underlying therapeutic principles in the empirical use of LS-containing formulations in DM and DM-related disorders as applied in TMM.

Abstract
In our previous studies, we have reported that leonurine, a plant phenolic alkaloid in Herba leonuri, exerted cardioprotective properties in a number of preclinical experiments. Herein, we investigated the roles and the possible mechanisms of leonurine for reducing fibrotic responses in angiotensin II (Ang II)-stimulated primary neonatal rat cardiac fibroblasts and post-myocardial infarction (MI) rats. In in vitro experiments performed in neonatal rat cardiac fibroblasts, leonurine (10-20 μM) pretreatment attenuated Ang II-induced activation of extracellular signal-regulated kinase 1/2, production of intracellular reactive oxygen species (ROS), expression and activity of matrix metalloproteinase (MMP)-2/9, and expression of α-smooth muscle actin and types I and III collagen. A small interfering RNA-mediated knockdown strategy for NADPH oxidase 4 (Nox4) revealed that Nox4 was required for Ang II-induced activation of cardiac fibroblasts. In vivo studies using a post-MI model in rats indicated that administration of leonurine inhibited myocardial fibrosis while reducing cardiac Nox4 expression, ROS production, NF-κB activation, and plasma MMP-2 activity. In conclusion, our results provide the first evidence that leonurine could prevent cardiac fibrosis and the activation of cardiac fibroblasts partly through modulation of a Nox4-ROS pathway.

Abstract
OBJECTIVES To investigate the anticancer activities of Chinese motherwort herb (Leonurus heterophyllus Sweet; LHS). DESIGN Dried LHS was extracted and reconstituted in phosphate-buffered saline. The in vitro antiproliferation activities of the extract were tested against seven human cancer cell lines. The DNA ladder assay and cell morphologic studies were performed to verify the drug's apoptotic activities. The possible pathway by which LHS induced apoptosis was also explored by examining mitochondrial depolarization, cytochrome c release, and caspase-3 activation. RESULTS The LHS extract was effective in inhibiting the growth of all seven cancer cell lines tested. The IC(50) (50% inhibition concentrations, milligrams of raw material per milliliter) were in the range of 8.0-40.0 when the drug exposure time was 48 hours. The inhibitory action of the herbal extract was time- and dose-dependent. A significant decrease in activity was seen when the drug exposure time was shortened. Microscopic examination of the LN CaP and other cancer cell lines after treatment with LHS revealed morphologic changes that are typical of cells undergoing apoptosis. DNA fragmentation was obvious in the DNA latter assay and this confirmed the induction of apoptosis of the cancer cells by LHS. The mitochondria of the LHS-treated cells were found to undergo depolarization. Cytochrome c was released into the cytosol from the LHS-treated cells but not from the control cells. Cells treated with LHS showed cleavage of the full-length poly[ADP(ribose)] polymerase (PARP; 112 kd) to generate the 85-kd cleaved PARP fragment indicating the activation of caspase-3. CONCLUSIONS LHS was able to induce apoptosis of all the tumor cell lines tested. The antiproliferation effect was dose- and time-dependent. The mitochondrion was found to be involved in the apoptosis induced by the LHS extract.
