Objective To determine the impact of Huangqi Guizhi decoction of five ingredients on hemorheology and inflammatory factors in patients with acute myocardial infarction (AMI) after percutaneous coronary intervention (PCI). Methods A total of 111 cases of AMI treated in Tongchuan Hospital of Traditional Chinese Medicine from February 2019 to February 2022 were analyzed retrospectively. Among them, 47 patients who received routine treatment were assigned to the control group, while those who received Huangqi Guizhi decoction of five ingredients in addition to the treatment of the control group were assigned to the study group. The clinical efficacy in the two groups was evaluated after therapy. The two groups were compared as to changes in serum inflammatory factors [tumor necrosis factor-α (TNF-α), high-sensitivity C-reactive protein (hs-CRP), and interleukin-6 (IL-6)] before and after therapy. The two groups were also compared as to differences in fibrinogen, plasma viscosity, whole blood low-shear viscosity (WBLSV), and whole blood high-shear viscosity (WBHSV) before and after therapy. Left ventricular end-diastolic dimension (LVEDD), left ventricular end-systolic diameter (LVESD), and left ventricular ejection fraction (LVEF) in the two groups were evaluated. In addition, the two groups were compared as to incidence of major adverse cardiovascular events (MACE) in 6 months. Logistic regression analysis was conducted to analyze the risk factors for MACE. Results The study group showed a significantly higher treatment efficacy than the control group (P Conclusion Huangqi Guizhi decoction of five ingredients contributes to higher efficacy in AMI and has the effects of inhibiting the inflammation and hemorheology of patients. In addition, age, history of TM, NYHA classification, hsCPR, and LVEF were independent risk factors for MACE.

Background Tongnao decoction (TND) has been extensively prescribed for the treatment of stroke. However, little is known about the role of TND in the progression of carotid atherosclerosis. Methods A mouse carotid atherosclerosis model was established with a silastic collar placed around the right common carotid artery and fed on Western diet for 12 weeks. The treatment group was given a gavage of TND at a dose of 1 mg/kg/d. The atherosclerotic lesion size and the compositions were observed using Oil red O staining and immunofluorescent staining. Enzyme-linked immunosorbent assay (ELISA) was used to evaluate the levels of lipid profiles, oxidative stress, and inflammatory factors. Human aortic endothelial cells (HAoECs) were treated with oxLDL with or without TND for in vitro experiments. Results TND treatment significantly suppressed the progression of atherosclerosis, as characterized with a smaller lesion size, less percentage of vascular smooth muscle cell proliferation, endothelial cell apoptosis, and macrophage infiltration. In addition, TND decreased the levels of lipid profiles, oxidative stress, and inflammatory factors in atherosclerosis. In vitro results showed that TND inhibited the apoptosis of endothelial cells via activating ERK and AKT pathway. Conclusions Our study demonstrated that TND significantly protected from atherosclerosis via promoting endothelial cell survival and alleviating oxidative stress and inflammatory response, which may have become a treatment in atherosclerotic diseases.

Background Acori Tatarinowii Rhizoma (ATR; rhizome of Acorus tatarinowii Schott) ( Shi Chang Pu ) is widely used in Chinese medicine (CM) to resuscitate, calm the mind, resolve shi ( dampness ) and harmonize the wei ( stomach ). Seven different species have been identified as belonging to the genus Acorus , all of which can be found in China. However, it can be difficult to distinguish the different species of Acorus because of their morphological similarities. The aim of this study was to authenticate Acorus species using macroscopic and microscopic techniques, chemical analysis and DNA authentication and to compare the resolution power and reliability of these different methods. Methods Four batches of ATR, Acori Graminei Rhizoma (AGR), Acori Calami Rhizoma (ACR) and Anemones Altaicae Rhizoma (AAR) (totaling 16 samples) were collected from Hong Kong and mainland China. The major characteristic features of these Acorus species were identified by macroscopic and microscopic examination. The identified samples were also analyzed by UHPLC analysis. Principal component analysis (PCA) and hierarchal clustering analysis (HCA) on UHPLC results were used to differentiate between the samples. An internal transcribed spacer (ITS) was selected as a molecular probe and a modified DNA extraction method was developed to obtain trace amounts of DNA from the different Acorus species. All extracted DNA sequences were edited by Bioedit and aligned with the ClustalW. And the sequence distances were calculated using the Maximum Parsimony method. Results Macroscopic and microscopic analyses allowed for AAR to be readily distinguished from ATR, AGR and ACR. However, it was difficult to distinguish between ATR, AGR and ACR because of their similar morphological features. Chemical profiling revealed that α- and β-asarone were only found in the ATR, AGR and ACR samples, but not in the AAR samples. Furthermore, PCA and HCA allowed for the differentiation of these three species based on their asarone contents. Morphological authentication and chemical profiling allowed for the partial differentiation of ATR, AGR ACR and AAR. DNA analysis was the only method capable of accurately differentiating between all four species. Conclusion DNA authentication exhibited higher resolution power and reliability than conventional morphological identification and UHPLC in differentiating between different Acorus species.

Background and aims Fumarioideae (20 genera, 593 species) is a clade of Papaveraceae (Ranunculales) characterized by flowers that are either disymmetric (i.e. two perpendicular planes of bilateral symmetry) or zygomorphic (i.e. one plane of bilateral symmetry). In contrast, the other subfamily of Papaveraceae, Papaveroideae (23 genera, 230 species), has actinomorphic flowers (i.e. more than two planes of symmetry). Understanding of the evolution of floral symmetry in this clade has so far been limited by the lack of a reliable phylogenetic framework. Pteridophyllum (one species) shares similarities with Fumarioideae but has actinomorphic flowers, and the relationships among Pteridophyllum, Papaveroideae and Fumarioideae have remained unclear. This study reassesses the evolution of floral symmetry in Papaveraceae based on new molecular phylogenetic analyses of the family. Methods Maximum likelihood, Bayesian and maximum parsimony phylogenetic analyses of Papaveraceae were conducted using six plastid markers and one nuclear marker, sampling Pteridophyllum, 18 (90 %) genera and 73 species of Fumarioideae, 11 (48 %) genera and 11 species of Papaveroideae, and a wide selection of outgroup taxa. Floral characters recorded from the literature were then optimized onto phylogenetic trees to reconstruct ancestral states using parsimony, maximum likelihood and reversible-jump Bayesian approaches. Key results Pteridophyllum is not nested in Fumarioideae. Fumarioideae are monophyletic and Hypecoum (18 species) is the sister group of the remaining genera. Relationships within the core Fumarioideae are well resolved and supported. Dactylicapnos and all zygomorphic genera form a well-supported clade nested among disymmetric taxa. Conclusions Disymmetry of the corolla is a synapomorphy of Fumarioideae and is strongly correlated with changes in the androecium and differentiation of middle and inner tepal shape (basal spurs on middle tepals). Zygomorphy subsequently evolved from disymmetry either once (with a reversal in Dactylicapnos) or twice (Capnoides, other zygomorphic Fumarioideae) and appears to be correlated with the loss of one nectar spur.

Sanfujiu is a treatment method of applying herbal paste onto the acupoints Fengmen and Feishu during the three hottest days of summer to treat patients with allergies. The objectives of this study were to determine the treatment efficacy at 1 year after the Sanfujiu treatment, and examine variations in the perceived efficacy of Sanfujiu among different subgroups, based on the patients' ages, diagnoses and number of reactive symptoms immediately after the treatment. We enrolled 105 patients who completed Sanfujiu treatment at a medical university hospital in Taipei as the subjects. One year after treatment, trained interviewers conducted telephone interviews with the patients. Approximately 60% of them perceived the treatment as being effective at 1 year later, which was higher than that at 1 week after treatment (45.7%). Younger subjects (<19 years of age) and patients with asthma were more likely to report the treatment as being effective. Patients who had more reactive symptoms after the third Sanfujiu treatment were more likely to report the treatment as being effective. The results demonstrated that Sanfujiu was moderately effective, as perceived by patients in Taiwan, in treating their allergic symptoms.
