ObjectiveTo investigate the anti-Alzheimer's disease (AD) effect of Dipsacus asper(DA) in the Caenorhabditis elegans model, and decipher the underlying mechanism via the peroxisome proliferator-activated receptor α (PPARα)/transcription factor EB (TFEB) pathway. MethodsFirst, transgenic AD C. elegans individuals were assigned into the blank control, model, positive control (WY14643, 20 µmol·L-1), and low-, medium-, and high-dose (100, 200, and 400 mg·L-1, respectively) DA groups. The amyloid β-42 (Aβ42) formation in the muscle cells, the paralysis time, and the deposition of amyloid β-protein (Aβ) in the head were detected. The lysosomal autophagy in the BV2 cell model was examined by Rluc-LC3wt/G120A. The expression levels of lysosomal autophagy-related proteins LC3Ⅱ, LC3I, LAMP2, and TFEB were detected by Western blot. Real-time quantitative polymerase chain reaction (Real-time PCR) was employed to determine the mRNA levels of autophagy-related genes beclin1 and Atg5 and lysosome-related genes LAMP2 and CLN2 downstream of PPARα/TFEB. A reporter gene assay was used to detect the transcriptional activities of PPARα and TFEB. Immunofluorescence was used to detect the fluorescence intensity of PPARα, and the active components of the ethanol extract of DA were identified by UPLC-MS. RCSB PDB, Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform (TCMSP), and Autodock were used to analyze the binding between the active components and PPARα-ligand-binding domain (LBD). ResultsCompared with the model group, the positive control group and 200 and 400 mg·L-1 DA groups showed prolonged paralysis time (P<0.05), and all the treatment groups showed decreased Aβ deposition in the head (P<0.01). DA within the concentration range of 50-500 mg·L-1 did not affect the viability of BV2 cells. In addition, DA enhanced the autophagy flux (P<0.05), up-regulated the mRNA levels of beclin1, Atg5, LAMP2, and CLN2 (P<0.05, P<0.01), promoted the nuclear translocation of TFEB (P<0.05), increased LAMP2 expression and autophagy flux (P<0.05, P<0.01), and enhanced the transcriptional activities of PPARα and TFEB (P<0.01). The positive control group and 200 and 400 mg·L-1 DA groups showed enhanced fluorescence intensity of PPARα in the BV2 nucleus (P<0.01). UPLC-MS detected nine known compounds of DA, from which 8 active components of DA were screened out. The docking results suggested that a variety of components in DA could bind to PPARα-LBD and form stable hydrogen bonds. ConclusionDA may reduce the pathological changes in AD by regulating the PPARα-TFEB pathway.

This article systematically reviews and verifies the medicinal materials of Dioscoreae Hypoglaucae Rhizoma(DHR), Dioscoreae Spongiosae Rhizoma(DSR), Smilacis Chinae Rhizoma(SCR) and Smilacis Glabrae Rhizoma(SGR) from the aspects of name, origin, producing area, quality, harvesting, processing and efficacy by consulting historical literature, in order to provide reference for the development and utilization of famous classical formulas containing the four medicinal materials. DHR, DSR, SCR and SGR have a long history of application as medicinal materials. However, due to their similar growth environment and medicinal properties, as well as their functions of promoting dampness, dispelling wind and removing numbness, there have been instances of homonymous foreign objects and homonymous synonyms throughout history, resulting in confusion of the origin. Therefore, it is necessary to conduct comparative analysis and systematic research for clarifying the historical development and changes of the four, in order to provide a basis for safe and effective medication. According to research, Bixie was first recorded in Shennong Bencaojing and has been historically known as Baizhi, Chijie, Zhumu, and other aliases. From ancient times to the mid-20th century, there has always been a situation where the rhizomes of Dioscorea plants and Smilax plants, and even the rhizomes of Heterosmilax plants, were mixed together to be used as medicinal herbs for Bixie. However, since the Tang dynasty, it has been clearly advocated that the rhizomes of Dioscorea plants have excellent quality and have been the mainstream throughout history. The 2020 edition of Chinese Pharmacopoeia categorized it into two types of medicinal herbs(DHR and DSR). Among them, the origin of DHR is the dry rhizomes of Dioscorea hypoglauca, and the origins of DSR are the dry rhizomes of D. spongiosa and D. futschauensis. In ancient times, due to different types, the corresponding production areas of DHR and DSR were also different. Nowadays, They are mainly produced in the southern region of the Yangtze River. Since the Tang dynasty, the quality of Bixie has been characterized by its white color and soft nature. In modern times, it has been summarized that those with white color, large and thin pieces, powdery texture, tough and elastic texture, and neat and unbreakable are the best. The harvesting times of DHR and DSR are in spring or autumn, with the best quality harvested in autumn. The mainstream processing methods of them are slicing and then using the raw products or wine-processed products. SCR was first recorded in Mingyi Bielu and has been known as Jinganggen, Tielingjiao, Tieshuazi, and other aliases in history. The mainstream source is the dry rhizomes of Smilax china in the past dynasties, with the best quality being those that are tough and rich in powder. The harvesting time is from the late autumn to the following spring, and the main processing method throughout history has been slicing for raw use. SGR was first recorded under the item of Yuyuliang in Variorum of Shennong's Classic of Materia Medica. It was listed as an independent medicinal material from Bencao Gangmu. In history, there were such aliases as Cao Yuyuliang, Lengfantuan, Xianyiliang, Tubixie, etc. The main source of the past dynasties was dry rhizomes of S. glabra. In history, there have also been instances of multiple plants belonging to the same genus, and even cases of mixing the rhizomes of plants in the genus Heterosmilax. It is mainly produced in Guangdong, Hunan, Hubei, Zhejiang, Sichuan, Anhui and other regions, its quality has been summarized as large in size, powdery in texture, with few veins, and light brown in cross-section since modern times. The harvesting time is in spring or autumn, and the main processing method throughout history has been slicing for raw use. DHR, DSR, SCR and SGR all have the effects of promoting dampness, dispelling wind, relieving rheumatism and detoxifying. However, their detoxification abilities are ranked as follows:SGR>SCR>Bixie(DHR and DSR). Especially for the treatment of limb spasms, arthralgia and myalgia, scrofula, and scabies caused by syphilis and mercury poisoning, SGR has a unique effect. Based on the research results, DHR is recommended to develop the famous classical formulas containing Bixie as the first choice for medicinal herbs. It should be harvested in autumn, sliced thinly while fresh, and processed according to the requirements of the famous classical formulas, without any requirements for raw use. Selecting the rhizomes of S. china, harvested in late autumn, and thinly sliced while fresh. If there are no special processing requirements in the formulas, use it raw. Selecting the rhizomes of S. glabra, it is harvested in autumn and thinly sliced while fresh. If there are no special processing requirements in the formulas, raw products can be used.

Breast cancer is a kind of malignant tumor with a complex mechanism, and its morbidity and mortality are increasing year by year, which seriously threatens women's health. At present, the main clinical treatments are surgical resection, radiotherapy, chemotherapy, and drug therapy, but they are often accompanied by side effects and adverse reactions, which affect the therapeutic effect. Traditional Chinese medicine (TCM) has the advantages of multi-component and multi-target treatment in the fight against breast cancer. The wnt/β-catenin signaling pathway is one of the classic pathways in cancer research. Abnormally activated Wnt/β-catenin signaling pathway inhibits β-catenin degradation by blocking the formation of Axin/glycogen synthase kinase 3β/adenomatous polyposis coli complex, thus promoting β-catenin nuclear metastasis, and it binds to T cell transcription factor/lymphoenhancer factor-1 to initiate downstream target genes and further interfere with the proliferation, migration, and invasion of tumor cells to affect the tumor process. Previous studies have shown that TCM monomers and compounds can mediate the Wnt/β-catenin signaling pathway to inhibit the malignant phenotype of breast cancer cells, thus playing an anti-breast cancer role, and the biochemical process involved in the regulation of therapeutic drugs has not been systematically combed. By analyzing and collating Chinese and foreign literature at the present stage, this paper discussed the association mechanism between Wnt/β-catenin signaling pathway and breast cancer and analyzed the internal mechanism of TCM monomers and compounds in mediating Wnt/β-catenin signaling pathway to exert anti-breast cancer effect. The statistical results showed that the flavonoids, alkaloids, and terpenoids in TCM monomers could target the Wnt/β-catenin signaling pathway and block the further development of malignant phenotype of breast cancer cells. TCM compounds with functions of clearing heat and detoxifying, promoting blood circulation and removing blood stasis, and tonifying kidney and liver were commonly used to intervene in the Wnt/β-catenin signaling pathway to prevent breast cancer. Compared with the current inhibitors of Wnt/β-catenin signaling pathway, the application of TCM monomers and compounds is expected to bring low-toxicity and high-efficiency breast cancer treatment drugs to the clinical practice, and the existing results provide a reference for the subsequent screening, research, and development of TCM small-molecule compounds and TCM compounds against breast cancer.

OBJECTIVE To provide a reference for the pharmaceutical care of a patient with type 2 diabetes mellitus (T2DM) and limb-girdle muscular dystrophy (LGMD) who developed euglycemic diabetic ketoacidosis (euDKA) after taking empagliflozin. METHODS Clinical pharmacists provided pharmaceutical care for a patient with T2DM and LGMD who developed euDKA after taking empagliflozin. According to the patient’s recent use of medications and his conditions, clinical pharmacists assessed the correlation between euDKA and empagliflozin as “very likely”. As to euDKA, clinical pharmacists suggested discontinuing empagliflozin and metformin, and giving intravenous infusion of 10% Glucose injection instead of 5% Glucose injection for fluid resuscitation. Clinical pharmacists monitored the patient’s laboratory indicators such as arterial blood gas analysis, blood/urine ketones and electrolytes. They assisted physicians to decide when to stop intravenous supplements of liquid and insulin. Clinical pharmacists also assisted physicians to adjust the antidiabetic drugs and educated the patient to avoid empagliflozin or other sodium- glucose linked transporter 2 inhibitors (SGLT2i). RESULTS Physicians adopted the suggestions of clinical pharmacists. After treatment, the patient’s condition improved, and he was allowed to be discharged with medication. CONCLUSIONS euDKA is a relatively rare and serious adverse reaction associated with SGLT2i, and the patients with LGMD are susceptible to euDKA. Clinical pharmacists assist physicians in developing personalized medication plans by evaluating the association between euDKA and empagliflozin, adjusting medication regimens,conducting pharmaceutical monitoring,and other pharmaceutical services. Meanwhile, they provide medication education to patients to ensure their medication safety.

Knee osteoarthritis (KOA) is a prevalent degenerative joint disease characterized by synovial inflammation, cartilage loss. Often manifesting as joint pain and limited mobility, it severely affects the quality of life of patients. Traditional treatment methods such as pharmacological injections and surgical interventions primarily aim to alleviate symptoms but have limited effects on cartilage repair. Human umbilical cord mesenchymal stem cells (hUC-MSCs), due to their anti-inflammatory and chondrogenic capabilities, is considered a new hope for the treatment of KOA. This article synthesizes the latest research findings from both domestic and international sources to discuss the theoretical basis for the clinical application of hUC-MSCs in treating KOA, clinical study design, and efficacy evaluation. It also addresses the challenges in the clinical application of hUC-MSCs and explores future directions, in the hope of providing feasible theoretical support for the treatment of KOA with hUC-MSCs.

Acute lung injury (ALI) is one of the most common and critical diseases in clinical practice, with extremely high morbidity and mortality, seriously threatening human life and health. The pathogenesis of ALI is complex, in which the inflammatory response is a key factor. Studies have shown that NOD-like receptor protein 3 (NLRP3) inflammasomes are involved in ALI through mechanisms such as inflammation induction, increased microvascular permeability, recruitment of neutrophils, oxidative stress, and pyroptosis, playing a key role in the occurrence and progression of ALI. Therefore, regulating NLRP3 inflammasomes and inhibiting the release of inflammatory factors can alleviate the damage in ALI. At present, ALI is mainly treated by mechanical ventilation and oxygen therapy, which have problems such as high costs and poor prognosis. In recent years, studies have shown that traditional Chinese medicine (TCM) can reduce the inflammatory response and the occurrence of oxidative stress and pyroptosis by regulating the NLRP3 inflammasome, thus alleviating the damage and decreasing the mortality of ALI. Based on the relevant literature in recent years, this article reviews the research progress in TCM treatment of ALI by regulating NLRP3 inflammasomes, discusses how NLRP3 inflammasomes participate in ALI, and summarizes the active ingredients, extracts, and compound prescriptions of TCM that regulate NLRP3 inflammasomes, aiming to provide new ideas for the clinical treatment of ALI and the development of relevant drugs.

Alzheimer’s disease (AD) is a central neurodegenerative disease characterized by progressive cognitive decline and memory impairment in clinical. Currently, there are no effective treatments for AD. In recent years, a variety of therapeutic approaches from different perspectives have been explored to treat AD. Although the drug therapies targeted at the clearance of amyloid β-protein (Aβ) had made a breakthrough in clinical trials, there were associated with adverse events. Neuroinflammation plays a crucial role in the onset and progression of AD. Continuous neuroinflammatory was considered to be the third major pathological feature of AD, which could promote the formation of extracellular amyloid plaques and intracellular neurofibrillary tangles. At the same time, these toxic substances could accelerate the development of neuroinflammation, form a vicious cycle, and exacerbate disease progression. Reducing neuroinflammation could break the feedback loop pattern between neuroinflammation, Aβ plaque deposition and Tau tangles, which might be an effective therapeutic strategy for treating AD. Traditional Chinese herbs such as Polygonum multiflorum and Curcuma were utilized in the treatment of AD due to their ability to mitigate neuroinflammation. Non-steroidal anti-inflammatory drugs such as ibuprofen and indomethacin had been shown to reduce the level of inflammasomes in the body, and taking these drugs was associated with a low incidence of AD. Biosynthetic nanomaterials loaded with oxytocin were demonstrated to have the capability to anti-inflammatory and penetrate the blood-brain barrier effectively, and they played an anti-inflammatory role via sustained-releasing oxytocin in the brain. Transplantation of mesenchymal stem cells could reduce neuroinflammation and inhibit the activation of microglia. The secretion of mesenchymal stem cells could not only improve neuroinflammation, but also exert a multi-target comprehensive therapeutic effect, making it potentially more suitable for the treatment of AD. Enhancing the level of TREM2 in microglial cells using gene editing technologies, or application of TREM2 antibodies such as Ab-T1, hT2AB could improve microglial cell function and reduce the level of neuroinflammation, which might be a potential treatment for AD. Probiotic therapy, fecal flora transplantation, antibiotic therapy, and dietary intervention could reshape the composition of the gut microbiota and alleviate neuroinflammation through the gut-brain axis. However, the drugs of sodium oligomannose remain controversial. Both exercise intervention and electromagnetic intervention had the potential to attenuate neuroinflammation, thereby delaying AD process. This article focuses on the role of drug therapy, gene therapy, stem cell therapy, gut microbiota therapy, exercise intervention, and brain stimulation in improving neuroinflammation in recent years, aiming to provide a novel insight for the treatment of AD by intervening neuroinflammation in the future.

Objective To construct a glioma microfluidic chip model to simulate tumor microenvironment for evaluating the medicinal efficacy of anti-glioma traditional Chinese medicines. Methods Glioblastoma cells U251 were seeded into microfluidic chips with different culture modes, and the cell viability and tumour microenvironment within the constructed model were characterized. Fluorescence staining was used to evaluate the effects of the positive drugs temozolomide (TMZ) and docetaxel (DOC) on the cell activity and apoptosis within the model, which was applied to evaluate the medicinal efficacy of the extracts of the herb Scutellaria barbata on gliomas. Results The cells in the constructed U251 microfluidic chip model displayed high viability and were able to mimic the hypoxic microenvironment of tumor to a certain extent. The viability of the U251 cells in the microfluidic chips decreased with the increasing of the concentration of the positive drug, and the viability of the 3D cultured U251 cells was higher than that in the 2D condition (P<0.05). The intracellular mitochondrial membrane potential decreased with the increasing of the concentration of the positive drug. And the 2 mg/ml Scutellaria barbata extract killed U251 cells to a certain extent and reduced the mitochondrial membrane potential of the cells in the model. Conclusion This study successfully constructed a microfluidic chip model of glioma that could effectively simulate the tumor microenvironment and rapidly evaluate the anti-tumor medicinal efficacy, which provided a new strategy for the medicinal efficacy evaluation and active components screening of anti-glioma traditional Chinese medicines.
