ObjectiveTo explore the effects of Renshentang on atherosclerosis (AS) in mice based on the role of transient receptor potential vanilloid1 (TRPV1) in regulating cholesterol metabolism in foam cells. MethodsNine SPF-grade 8-week-old C57BL/6J mice were set as a normal group, and 60 ApoE-/- mice were randomized into model, positive drug (simvastatin, 0.02 g·kg-1·d-1), and low-, medium-, and high-dose (1.77, 3.54, 7.08 g·kg-1·d-1, respectively) Renshentang groups (n=12) according to body weight. The normal group was fed with a normal diet, and the other groups were fed with a high-fat diet and given corresponding drugs by oral gavage for the modeling of AS. The mice were administrated with corresponding drugs once a day for 12 weeks. After the last administration and fasting for 12 h, the aorta was collected. Plaque conditions, pathological changes, levels of total cholesterol (TC), triglcerides (TG), low-density lipoprotein-cholesterol (LDL-C), and high-density lipoprotein-cholesterol (HDL-C), and the expression of TRPV1, liver X receptor (LXR), inducible degrader of the low-density lipoprotein receptor (IDOL), and low-density lipoprotein receptor (LDLR) in the aortic tissue were observed and detected by gross oil red O staining, HE staining, Western blot, immunohistochemistry, and real-time PCR. ResultsCompared with the normal group, the model group presented obvious plaque deposition in the aorta, raised levels of TC, TG, and LDL-C in the serum (P<0.01), up-regulated expression level of LDLR in the aorta (P<0.01), lowered level of HDL-C in the serum, and down-regulated expression levels of TRPV1, LXR, and IDOL in the aorta (P<0.05, P<0.01). Compared with the model group, the positive drug and Renshentang at different doses alleviated AS, elevated the levels of HDL-C, TRPV1, LXR, and IDOL (P<0.05, P<0.01), while lowering the levels of TC, TG, LDL-C, and LDLR (P<0.05, P<0.01). ConclusionRenshentang has a lipid-lowering effect on AS mice. It can effectively reduce lipid deposition, lipid levels, and plaque area of AS mice by activating TRPV1 expression and regulating the LXR/IDOL/LDLR pathway.

OBJECTIVE:
To observe the clinical efficacy of acupoint thread-embedding therapy of regulating governor vessel, dispersing lung, and suppressing reflux for gastroesophageal reflux cough (GERC).
METHODS:
A total of 120 GERC patients were randomly assigned to an observation group (60 cases, 1 case dropped out) and a control group (60 cases, 1 case was eliminated). The observation group received acupoint thread-embedding treatment at positive response points of governor vessel. If no such points were detected, the following acupoints were used: Dazhui (GV14), Fenghu (Extra), Shendao (GV11), Lingtai (GV10), and Zhiyang (GV9). Treatment was administered once every two weeks. The control group received oral rabeprazole enteric capsules at 20 mg twice daily. All the treatment was given for 6 weeks. Clinical outcomes were assessed using cough symptom score, reflux disease questionnaire (RDQ) score, and Leicester cough questionnaire (LCQ) score before and after treatment in the two groups. Clinical efficacy was also compared between the two groups.
RESULTS:
After treatment, both groups showed decreased cough symptom scores and the each item scores and total scores of RDQ (P<0.001), and increased LCQ scores (P<0.001) compare with those before treatment. The observation group exhibited lower cough symptom score and chest pain, reflux and total score of RDQ, and higher LCQ score compared to those in the control group (P<0.05). The total effective rate in the observation group was 94.9% (56/59), which was higher than 84.7% (50/59) in the control group (P<0.05).
CONCLUSION
Acupoint thread-embedding therapy of regulating governor vessel, dispersing lung, and suppressing reflux could effectively alleviate cough and reflux symptoms in patients with GERC and improve their quality of life.

China is a high-incidence region for gastric cancer globally. The disease is characterized by a high morbidity rate, low early diagnostic rate, and poor long-term outcomes, imposing a significant burden on both patients and society. Therefore, exploring the pathogenesis of gastric cancer, developing novel therapeutic strategies, and identifying new drug targets is of great importance. Telomerase expression is broadly associated with cancer cell targeting, and its up-regulation is one of the key factors driving the initiation and progression of gastric cancer. Additionally, telomerase is intricately involved in the regulation of autophagy and autophagy-associated cell death. While autophagy can induce chemoresistance, excessive autophagy may lead to cell death, which also constitutes one of the mechanisms of chemotherapy. Telomerase not only directly contributes to gastric cancer pathogenesis but also indirectly influences its development and treatment by modulating autophagy and autophagic cell death. Therefore, telomerase holds promise as a novel therapeutic target in gastric cancer.

ObjectiveTo investigate the mechanism and effect of Qingfei Paidu decoction on transient receptor potential vanilloid-1/Transient receptor potential ankyrin1 (TRPV1/TRPA1) based on heat-sensitive channel and inflammatory response. MethodAccording to body weight, 80 8-week-old C57BL/6 mice were randomly divided into the normal group, model group, dexamethasone group (5 mg·kg-1), and low-dose, medium-dose, and high-dose groups of Qingfei Paidu decoction (14.865, 29.73, 59.46 g·kg-1), with 12 mice in each group. In addition to the normal group, the other groups were administered 20 μL (1×10-3 g·kg-1) to each mouse by airway infusion to establish the acute lung injury (ALI) model. In the administration group, the drug was given 1 h after modeling and again after an interval of 24 h. The lung tissue was taken 36 h after modeling. Double lung wet/dry weight ratio(W/D), hematoxylin-eosin (HE) staining, enzyme-linked immunosorbent assay (ELISA), and Western blot were used to observe and detect the pathological changes of lung tissue, expression levels of inflammatory cytokine tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6), and expressions of TRPV1 and TRPA1 proteins in heat-sensitive channel, nuclear factor kappa-B (NF-κB), inhibitor of NF-κB (IκBα) in inflammatory pathway, and phosphorylated proteins. The phosphorylated protein/total protein ratio was calculated. ResultCompared with that in the normal group, the lung tissue of mice in the model group was seriously damaged, and pulmonary capillary permeability increased. Alveolar capillary congestion and dilation destroyed the complete structure of the alveolar, and the alveolar wall thickened. A large number of inflammatory cells and red blood cells were infiltrated, and pulmonary edema was significantly aggravated. The expressions of TNF-α, IL-6, TRPV1, TRPA1, phosphorylated NF-κB p65/NF-κB p65, and phosphorylated IκBα/IκBα were significantly increased (P<0.01), and the whole lung W/D was significantly increased (P<0.01). Compared with the model group, the dexamethasone group and low-dose, medium-dose, and high-dose groups of Qingfei Paidu decoction could significantly improve pulmonary edema. TNF-α, IL-6, TRPV1, TRPA1, lung tissue NF-κB p65, and IκBα phosphorylated protein/total protein ratio decreased significantly (P<0.05, P<0.01). The whole lung W/D also decreased significantly (P<0.05, P<0.01). ConclusionQingfei Paidu decoction has anti-inflammatory and protective effects on LPS-ALI mice, which can effectively reduce inflammation, induce diuresis, and alleviate edema. Its mechanism may be related to the regulation of the expression of TRPA1 and TRPV1 and the inhibition of the activation of the NF-κB pathway.

OBJECTIVE
To explore the mechanism of Baihe Dihuang decoction in the treatment of Alzheimer's disease(AD) based on network pharmacology, molecular docking and animal experiment.
METHODS
TCMSP were used to predict the active components and targets of Baihe Dihuang decoction and disease-related targets were collected from GeneCards, OMIM and DRUGBANK databases, respectively. Target protein interactions were analyzed with STRING database and biological function and pathway were analyzed with Metascape database. Lastly relevant results were analyzed with Cytoscape 3.8.0. AutoDock vina software was used for molecular docking to analyze the binding energy of the active components and key targets of Baihe Dihuang decoction. PyMOL software were used to visualize the optimal docking results. ICR male mice were randomly divided into control group, model group, Rolipram group, low, medium and high dose group of Baihe Dihuang decoction. After 14 days of administration, the neurobehavioral scores of mice in each group were collected, and the expression of related proteins in brain tissue was detected, ELISA and Western blotting were used to detect the expression of the key protein cAMP, PKA, p-CREB and BDNF. At last, the adverse reaction of Baihe Dihuang decoction was observed by vomiting experiment.
RESULTS
A total of 13 active components and 39 key targets were collected from network pharmacology. The docking results showed that the first 10 core targets all performed well and their effects were closely related to PRKACA. Compared with the control group, the model group mice's recognition rate of new objects and the spontaneous alternation reaction rate were significantly reduced, the escape latency was significantly prolonged, and the target quadrant stay time, the number of crossing platforms were significantly reduced; cAMP, PKA, p-CREB and BDNF in the hippocampus of mice was significantly decreased. Baihe Dihuang decoction could reverse the behavior of AD mice and the expression of cAMP, PKA, p-CREB and BDNF. In the vomiting experiment, the anesthesia recovery time of the Rolipram group was significantly prolonged, while that of the Baihe Dihuang decoction group was not significantly affected.
CONCLUSION
The mechanism of Baihe Dihuang decoction in the treatment of AD may be related to its influence on cAMP-PKA and regulation of cAMP-PKA-CREB-BDNF signal pathway, and the adverse reactions are milder than those of clopramide.

ObjectiveTo explore the effect and mechanism of Zhishi Xiebai Guizhitang on the progression of atherosclerosis (AS) mice based on the regulation of cholesterol metabolism in foam cells by transient receptor potential channel ankyrin 1 (TRPA1). MethodThe AS model was established on apolipoprotein E knockout (ApoE-/-) mice with a high-fat diet. The mice were randomly divided into low-dose, middle-dose, and high-dose groups of Zhishi Xiebai Guizhitang (2.97, 5.94, 11.88 g·kg-1) and simvastatin group (0.002 g·kg-1), and the drug was administered along with a high-fat diet. C57BL/6J mice were fed an ordinary diet as a normal group. After the above process, the aorta and serum of mice were taken. The pathological changes of the aortic root were observed by hematoxylin-eosin (HE) staining. The lipid plaques in the aorta were observed by gross oil redness. Serum levels of total cholesterol (TC), triglyceride (TG), low density lipoprotein cholesterol (LDL-C), and high density lipoprotein cholesterol (HDL-C) were detected, and the levels of interleukin-1β (IL-1β) and interleukin-18 (IL-18) were detected by enzyme-linked immunosorbent assay (ELISA). Western blot and immunohistochemical method were used to analyze the expression of TRPA1, ATP-binding cassette transporter A1 (ABCA1), ATP-binding cassette transporter G1 (ABCG1), and mannose receptor (CD206). ResultFrom the perspective of drug efficacy, compared with the normal group, pathological changes such as plaque, a large number of foam cells, and cholesterol crystals appeared in the aorta of the model group, and the serum levels of TC, LDL-C, IL-1β, and IL-18 were significantly increased (P<0.01). The HDL-C level was significantly decreased (P<0.01), and the CD206 level in aortic tissue was significantly decreased (P<0.01). Compared with the model group, the lipid deposition in the aorta was alleviated in all drug administration groups. In addition, except for the high-dose group of Zhishi Xiebai Guizhitang, all drug administration groups could significantly decrease the levels of TC and LDL-C (P<0.01). In terms of inflammation, except for the middle-dose group of Zhishi Xiebai Guizhitang, the levels of IL-1β and IL-18 were significantly decreased in all drug administration groups (P<0.05). Moreover, Zhishi Xiebai Guizhitang could also up-regulate the levels of CD206, and the difference was significant in the middle-dose and high-dose groups (P<0.05). From the perspective of mechanism, the expression levels of TRPA1, ABCA1, and ABCG1 in the aorta in the model group were lower than those in the normal group (P<0.05). Compared with the model group, all drug administration groups significantly increased the expression of TRPA1 in the aorta (P<0.05), and the expressions of ABCA1 and ABCG1 were increased. The differences in the middle-dose and high-dose groups and the simvastatin group were significant (P<0.05), which was basically consistent with the trend of immunohistochemical results. ConclusionZhishi Xiebai Guizhitang can effectively reduce blood lipid and inflammation levels and inhibit the formation of aortic plaque. The mechanism may be explained as follows: the expressions of ABCA1 and ABCG1 downstream are increased through TRPA1, which promotes cholesterol outflow in foam cells, thereby regulating cholesterol metabolism, intervening in inflammation level to a certain extent, and finally treating AS.

Gastric cancer is one of the major diseases threatening human health, with a high incidence and a low early diagnostic rate. There are many bottlenecks encountered during its treatment. Consequently, improving the early diagnostic rate and exploring new therapeutic targets are currently urgent challenges that need to be addressed. Telomerase is undetectable in normal tissues, but it exhibits high specificity and sensitivity in most cancers and has a definite correlation with prognosis. It may serve as a serum tumor marker and prognostic indicator. Human telomerase reverse transcriptase (hTERT) gene polymorphism can regulate the susceptibility of people to gastric cancer, and affect the occurrence, development, proliferation and apoptosis of gastric cancer through its target gene. Substances such as resistin, visfatin, G-quadruplex and methylenedioxyaniline can affect the occurrence and development of gastric cancer by regulating telomerase expression. The mechanism by which hTERT regulates tumor invasion and metastasis is currently unclear, so elucidating its mechanism is of great significance.This paper will review the research progress of this mechanism in recent years.
