Menstrual migraine is a specific subtype of migraine unique to women,closely related to the menstrual cycle,characterized by periodic and intractable headaches,often accompanied by nausea,vomiting or photophobia and phonophobia,which seriously affects life and has a high degree of disability.Its pathogenesis is complex,involving multi-dimensional regulation such as estrogen fluctuations,neurovascular responses and genetic and environmental factors,but the specific mechanism has not been fully clarified.In recent years,with the increasing social attention to women's health,the clinical research demand for menstrual migraine has become increasingly urgent.Currently,modern medicine can alleviate symptoms through acute drug intervention(such as non-steroidal anti-inflammatory drugs,triptans)and preventive treatment(such as beta-blockers,CGRP antagonists),but there are problems such as drug dependence and insufficient individualization.Traditional Chinese medicine,based on the"holistic concept"and"syndrome differentiation and treatment"theory,regulates the balance of qi,blood,yin and yang through therapies such as traditional Chinese medicine and acupuncture,showing unique advantages in improving symptoms and preventing recurrence.The combination of traditional Chinese and Western medicine can optimize the therapeutic effect and reduce side effects through synergistic effects,but the full-cycle prevention and treatment strategy still needs further exploration.This article systematically reviews the pathogenesis and research progress of treatment of menstrual migraine in traditional Chinese and Western medicine,emphasizes the interaction between hormone fluctuations and neurovascular responses,and proposes an individualized intervention plan based on the menstrual cycle,providing new ideas for clinical practice and reference directions for future research.

Objective:To investigate the protective effects and mechanisms of targeted inhibition of type 3 deiodinase (Dio3) on skeletal muscle mitochondria in sepsis.Methods:① In vivo experiments: adeno-associated virus (AAV) was employed to specifically target Dio3 expression in the anterior tibial muscle of rats, and a septic rat model was generated using cecal ligation and puncture (CLP). The male Sprague-Dawley (SD) rats were divided into shNC+Sham group, shD3+Sham group, shNC+CLP group, and shD3+CLP group by random number table method, with 8 rats in each group. After CLP modeling, tibial samples were collected and Western blotting analysis was conducted to assess the protein levels of Dio3, peroxisome proliferator-activated receptor-γ coactivator-1α (PGC1α), and silence-regulatory protein 1 (SIRT1). Real-time fluorescence quantitative polymerase chain reaction (RT-qPCR) was utilized to examine mRNA expression of genes including thyroid hormone receptors (THRα, THRβ), monocarboxylate transporter 10 (MCT10), mitochondrial DNA (mtDNA), and PGC1α. Transmission electron microscopy was employed to investigate mitochondrial morphology. ② In vitro experiments: involved culturing C2C12 myoblasts, interfering with Dio3 expression using lentivirus, and constructing an endotoxin cell model by treating cells with lipopolysaccharide (LPS). C2C12 cells were divided into shNC group, shD3 group, shNC+LPS group, and shD3+LPS group. Immunofluorescence colocalization analysis was performed to determine the intracellular distribution of PGC1α. Co-immunoprecipitation assay coupled with Western blotting was carried out to evaluate the acetylation level of PGC1α. Results:① In vivo experiments: compared with the shNC+Sham group, the expression of Dio3 protein in skeletal muscle of the shNC+CLP group was significantly increased (Dio3/β-Tubulin: 3.32±0.70 vs. 1.00±0.49, P < 0.05), however, there was no significant difference in the shD3+Sham group. Dio3 expression in the shD3+CLP group was markedly reduced relative to the shNC+CLP group (Dio3/β-Tubulin: 1.42±0.54 vs. 3.32±0.70, P < 0.05). Compared with the shNC+CLP group, the expression of T3-regulated genes in the shD3+CLP group were restored [THRα mRNA (2 -ΔΔCt): 0.67±0.05 vs. 0.33±0.01, THRβ mRNA (2 -ΔΔCt): 0.94±0.05 vs. 0.67±0.02, MCT10 mRNA (2 -ΔΔCt): 0.65±0.03 vs. 0.57±0.02, all P < 0.05]. Morphology analysis by electron microscopy suggested prominent mitochondrial damage in the skeletal muscle of the shNC+CLP group, while the shD3+CLP group exhibited a marked improvement. Compared with the shNC+Sham group, the shNC+CLP group significantly reduced the number of mitochondria (cells/HP: 10.375±1.375 vs. 13.750±2.063, P < 0.05), while the shD3+CLP group significantly increased the number of mitochondria compared to the shNC+CLP group (cells/HP: 11.250±2.063 vs. 10.375±1.375, P < 0.05). The expression of mtDNA in shNC+CLP group was markedly reduced compared with shNC+Sham group (copies: 0.842±0.035 vs. 1.002±0.064, P < 0.05). Although no difference was detected in the mtDNA expression between shD3+CLP group and shNC+CLP group, but significant increase was found when compared with the shD3+Sham group (copies: 0.758±0.035 vs. 0.474±0.050, P < 0.05). In the shD3+CLP group, PGC1α expression was significantly improved at both transcriptional and protein levels relative to the shNC+CLP group [PGC1α mRNA (2 -ΔΔCt): 1.49±0.13 vs. 0.68±0.06, PGC1α/β-Tubulin: 0.76±0.02 vs. 0.62±0.04, both P < 0.05]. ② In vitro experiments: post-24-hour LPS treatment of C2C12 cells, the cellular localization of PGC1α became diffuse; interference with Dio3 expression promoted PGC1α translocation to the perinuclear region and nucleus. Moreover, the acetylated PGC1α level in the shD3+LPS group was significantly lower than that in the shNC+LPS group (acetylated PGC1α/β-Tubulin: 0.59±0.01 vs. 1.24±0.01, P < 0.05), while the expression of the deacetylating agent SIRT1 was substantially elevated following Dio3 inhibition (SIRT1/β-Tubulin: 1.04±0.04 vs. 0.58±0.03, P < 0.05). When SIRT1 activity was inhibited by using EX527, PGC1α protein expression was notably decreased compared to the shD3+LPS group (PGC1α/β-Tubulin: 0.92±0.03 vs. 1.58±0.03, P < 0.05). Conclusion:Inhibition of Dio3 in skeletal muscle reduced the acetylation of PGC1α through activating SIRT1, facilitating nuclear translocation of PGC1α, thereby offering protection against sepsis-induced skeletal muscle mitochondrial damage.

Plasma metabolomics based on UHPLC-Q-TOF-MS/MS technique was developed for profiling the mechanism on attenuating hepatic fibrosis of Bupleuri Radix (BR) and Paeoniae Radix Alba (PRA) before and after vinegar-processing and compatibility, and to screen potential pharmacodynamic substances by spectrum-effect correlation method in this study. Firstly, SD rats with CCl₄-induced hepatic fibrosis were used as an in vivo model. The blood and tissue samples were collected for the analyses of pharmacodynamic indexes and plasma metabolomics after six weeks’ administration of BR, vinegar-processed BR (VPBR), PRA, vinegar-processed PRA (VPPRA), BR-PRA herb-pair, and VPBR-VPPRA herb-pair. The experiment was approved by the experimental animal ethics committee from Nanjing University of Chinese Medicine (No.202103A002). The results of pharmacodynamics indicated that the levels of alanine aminotransferase (ALT, P < 0.01), aspartate aminotransferase (AST, P < 0.01), and hydroxyproline (HYP, P < 0.01) were decreased significantly, while the level of glutathione peroxidase (GSH-Px, P < 0.05) was increased obviously after administration of all treatment groups. Next, UHPLC-Q-TOF-MS/MS was performed to characterize the endogenous metabolites. A total of 20 differential endogenous metabolites related to the pathogenesis of hepatic fibrosis were identified in positive and negative ion modes, mainly involving five metabolic pathways of retinol metabolism, glycerol phospholipid metabolism, glyceride metabolism, fatty acid biosynthesis, and arachidonic acid metabolism. Meanwhile, a concept named correction rate was introduced to evaluate the back-regulation effects of all treatment groups on differential metabolites, and 10 differential metabolites were corrected by all treatment groups. The correction effects of the vinegar-processed herb groups were better than those of the crude ones, and the correction effects of the herb-pair groups were better than those of the single ones. Interestingly, the best correction effect was found in the VPBR-VPPRA herb-pair group, which further verified the efficacy improvement through vinegar-processing and compatibility. Partial least square method and VIP analysis combined with spectrum-effect correlation were applied for screening pharmacodynamic markers, and 38 ingredients with higher correlation with four classical pharmacodynamic indexes (ALT, AST, HYP, and GSH-Px) were identified as pharmacodynamic markers of the anti-hepatic fibrosis effects of BR and PRA before and after vinegar-processing and compatibility. The results of the investigation could not only lay a foundation for clarifying the pharmacodynamic materials and mechanism of vinegar-processing and compatibility of BR and PRA in the treatment of hepatic fibrosis as well as provide a theoretical basis for demonstrating the scientific connotation of processing and compatibility, but also provide a reference for further drug design and development of BR and PRA in clinic.

A quantitative analysis method for six principal active constituents (acubin, geniposidic acid, chlorogenic acid, pinoresinol di-O-glucopyranoside, geniposide, and pinoresinol 4-O-glucopyranoside) of crude Eucommiae Cortex (EC) and its salt-processed product extracts was developed to investigate and compare their pharmacokinetic behaviors in adenine-induced renal fibrotic rats in vivo. UHPLC-QqQ-MS/MS technology was employed. Scan was conducted in negative ion mode and quantitative determination was carried out by MRM paired ion. The established method was fully validated by specificity, linearity, precision, accuracy, stability, recovery, and matrix effect, and the results of methodological investigation met the requirements of biological sample analysis. Then, a quick, sensitive, and accurate method was successfully established, which could simultaneously measure the contents of six active constituents of crude and salt-processed EC extracts in rat plasma. After a single administration to renal fibrotic rats of crude EC and its salt-processed product extracts, the plasma concentration of each constituent at different time points was measured, the pharmacokinetic parameters were calculated and the concentration time curves were structured. The experiment was approved by the experimental animal ethics committee from Nanjing University of Chinese Medicine (No. 202103A008). The results showed that compared to the crude Eucommiae Cortex group, the t_max of aucubin, pinoresinol di-O-glucopyranoside, geniposide, and pinoresinol 4-O-glucopyranoside in the salt-processed Eucommiae Cortex group rat plasma were significantly lower than those in the crude group (P < 0.05, P < 0.01); the C_max and AUC_{0-48 h} of chlorogenic acid, the C_max, AUC_{0-48 h} and AUC_0-∞ of pinoresinol di-O-glucopyranoside, and the C_max of geniposide and pinoresinol 4-O-glucopyranoside were significantly higher than those in the crude group (P < 0.05, P < 0.01). Our investigation found that compared to crude Eucommiae Cortex, a variety of active ingredients could play a role of quick effect with higher peak blood concentration and bioavailability after oral administration of salt-processed Eucommiae Cortex, which were consistent with the traditional Chinese medicine theory of "salt-processing enhancing drug into kidney meridian", providing an experimental basis for the selection of quality control indexes and the in-depth study of processing mechanisms and metabolic rules in vivo of Eucommiae Cortex and its salt-processed product.

OBJECTIVE: To derive the Chinese medicine (CM) syndrome classification and subgroup syndrome characteristics of ischemic stroke patients. METHODS: By extracting the CM clinical electronic medical records (EMRs) of 7,170 hospitalized patients with ischemic stroke from 2016 to 2018 at Weifang Hospital of Traditional Chinese Medicine, Shandong Province, China, a patient similarity network (PSN) was constructed based on the symptomatic phenotype of the patients. Thereafter the efficient community detection method BGLL was used to identify subgroups of patients. Finally, subgroups with a large number of cases were selected to analyze the specific manifestations of clinical symptoms and CM syndromes in each subgroup. RESULTS: Seven main subgroups of patients with specific symptom characteristics were identified, including M3, M2, M1, M5, M0, M29 and M4. M3 and M0 subgroups had prominent posterior circulatory symptoms, while M3 was associated with autonomic disorders, and M4 manifested as anxiety; M2 and M4 had motor and motor coordination disorders; M1 had sensory disorders; M5 had more obvious lung infections; M29 had a disorder of consciousness. The specificity of CM syndromes of each subgroup was as follows. M3, M2, M1, M0, M29 and M4 all had the same syndrome as wind phlegm pattern; M3 and M0 both showed hyperactivity of Gan (Liver) yang pattern; M2 and M29 had similar syndromes, which corresponded to intertwined phlegm and blood stasis pattern and phlegm-stasis obstructing meridians pattern, respectively. The manifestations of CM syndromes often appeared in a combination of 2 or more syndrome elements. The most common combination of these 7 subgroups was wind-phlegm. The 7 subgroups of CM syndrome elements were specifically manifested as pathogenic wind, pathogenic phlegm, and deficiency pathogens. CONCLUSIONS There were 7 main symptom similarity-based subgroups in ischemic stroke patients, and their specific characteristics were obvious. The main syndromes were wind phlegm pattern and hyperactivity of Gan yang pattern.
