Uterine fibroids are a common benign tumor of the female reproductive system， characterized by increased menstrual flow， lower abdominal pain， and prolonged menstrual periods. Modern medicine believes that the onset of this disease is related to genetic factors， environmental factors， hormone levels， et al， while the specific mechanism remains unclear， and the prevention and treatment of uterine fibroids has become a hot topic of concern for many experts and scholars in the medical field. At present， the treatment of uterine fibroids in clinical practice is mainly based on hormone drugs and uterine artery embolization， and severe cases require hysterectomy. However， the use of hormone drugs for treatment has serious side effects and is prone to recurrence after surgery. Since hysterectomy can cause severe harm to women， it is necessary to explore safer and more effective treatment methods. Traditional Chinese medicine （TCM） has rich clinical experience in the treatment of uterine fibroids， advocating for syndrome differentiation and treatment. The TCM methods that regulate Qi and blood and balance Yin and Yang have been commonly adopted， with significant efficacy and minimal side effects， being more conducive to the recovery. Guizhi Fulingwan are first recorded in the Synopsis of the Golden Chamber written by the famous medical expert ZHANG Zhongjing during the Eastern Han dynasty. This prescription has the effects of activating blood， resolving stasis， and eliminating mass， and it is thus mainly used for treating abdominal mass in women. In recent years， Guizhi Fulingwan has also been applied in the clinical treatment of tumors and has demonstrated definite efficacy in the treatment of uterine fibroids. Studies have shown that the therapeutic mechanisms of Guizhi Fulingwan for uterine fibroids involve regulating cell proliferation and apoptosis， improving immune function， reducing inflammation， improving hemorheological indicators， inhibiting tumor angiogenesis， and regulating sex hormone levels. This article mainly reviews the treatment of uterine fibroids with Guizhi Fulingwan from three aspects： theoretical basis， clinical application， and pharmacological mechanism. It is expected to provide scientific research ideas and guidance for exploring the clinical treatment of uterine fibroids.

Yin-Yang theory is one of the core components of the foundational theory of traditional Chinese medicine (TCM), yet its classification as philosophical or scientific has long been controversial. To move beyond the longstanding either-philosophy-or-science debate surrounding Yin-Yang theory in TCM, this article, for the first time, proposes a three-level framework spanning macro, meso, and micro perspectives. At the macro level, Yin and Yang are a theoretical achievement of ancient Chinese natural philosophy, used to explain universal laws governing how the cosmos operates, which constitutes Yin-Yang theory in philosophy; at the meso level, Huangdi Neijing (《黄帝内经》, Inner Canon of Huangdi) translated Yin-Yang from a cosmological framework into medical discourse, making it a core methodological basis for clinical pattern differentiation and treatment, which constitutes Yin-Yang theory in medicine; at the micro level, Yin-Yang theory in TCM has increasingly converged with modern science, showing scientific features that are testable and reproducible, which constitutes Yin-Yang theory in science. The article further demonstrates that Yin-Yang theory in TCM differs markedly from Yin-Yang as a general philosophical doctrine in core application and practical orientation: in the course of its medical transformation, elements related to life phenomena were selectively incorporated, while, within a medical context, abstract propositions such as cosmological speculation were bracketed and rendered concrete, thereby achieving a practice-oriented transition from philosophy to medicine. Based on this, the present study conducts analyses from four aspects, namely philosophical roots, clinical application, modern scientific interpretation, and implications for life sciences; it substantiates the logical basis for Yin-Yang theory in TCM as the overarching framework for clinical pattern differentiation and treatment, reviews modern research progress from perspectives such as systems science and network regulation, and explores its potential value in advancing a new paradigm of state-based medicine. The study suggests that an accurate understanding of Yin-Yang theory in TCM requires moving beyond the either-philosophy-or-science binary and analyzing specific issues on a case-by-case basis. Across different perspectives, Yin-Yang theory in TCM has philosophical, medical, and scientific attributes. Only by grounding the theory in actual clinical efficacy and engaging with modern science can the innovative development of Yin-Yang theory in TCM be promoted, thereby providing valuable Eastern insights for building a life science system with original Chinese contributions.

Objective To explore the effect of diet therapy on alcohol-induced chronic liver injury in rats and its relationship with TLR4 pathway.Methods According to Pueraria:Poria:Amomum villosum:Pericarpium Citri Reticulatae:Codonopsis:Zingiberis Rhizoma=15∶15∶10∶10∶10∶6,the water extract of the therapeutic prescription was prepared.A total of 78 female SD rats were randomly divided into 6 groups:normal group(n=12),model group(n=18),Hugan tablet group(0.35 g·kg-1,n=12),low-,medium-and high-dose Shiliaofang groups(2,6,18 g·kg-1,n=12).Except for the normal group,the rats in each group were induced alcoholic liver disease(ALD)by gradient alcohol gavage.After 10 weeks of intervention,the changes of body weight and water intake of rats were observed.The whole blood routine,serum alanine aminotransferase(ALT),aspartate aminotransferase(AST),triglyceride(TG),total cholesterol(TC)and liver malondialdehyde(MDA)were measured.The levels of serum alcohol dehydrogenase(ADH),aldehyde dehydrogenase(ALDH),lipopolysaccharide(LPS),D-lactic acid(D-LA),tumor necrosis factor-α(TNF-α),interleukin-6(IL-6)and interleukin-10(IL-10)were detected by enzyme-linked immunosorbent assay.HE staining was used to observe the pathological changes of liver and ileum.Oil red staining was used to observe liver fat deposition.Immunohistochemistry was used to detect the expression of ileal tight junction component occludin.Western blot was used to detect the expression of TLR4,MyD88 and NF-κB p65 protein in liver.Results Compared with the model group,the levels of WBC,LYC,TC,ALT,AST,LPS,D-LA,TNF-α and IL-6 in each diet group decreased,IL-10 increased,liver inflammatory cell infiltration and red lipid droplets decreased,intestinal villi were intact and densely arranged,the expression of occludin protein in ileum increased,and the expression of TLR4,MyD88 and NF-κB p65 protein in liver decreased.Conclusion The self-made dietotherapy prescription has a significant protective effect on chronic liver injury induced by alcohol in rats,which may be related to its down-regulation of TLR4-MyD88-NF-κB p65 protein expression and up-regulation of ileal occludin protein expression,improvement of intestinal mucosal barrier function,reduction of endotoxin entry into the liver,activation of TLR4/MyD88/NF-κB pathway,thereby reducing the second hit to the liver.This diet can be developed as a potential anti-alcoholic liver injury drug.

This study was aimed atanalyzing the epidemic characteristics of dengue fever in Ruili City atthe China-Myanmar bor-der in late 2023,to provide evidence for local dengue fever prevention and control measures.Adult Aedes mosquitoes were collected from Ruili City with a backpack type mosquito sucking machine in October of 2023.Serum samples frompatients with suspected den-gue were collected in acutephase,in November of 2023.Detection ofdengue virus(DENV)nucleic acids in Aedesmosquitoes and acute phase serum samples from suspected dengue fever patients using reverse transcription-polymerase chain reaction,and nucleic acid positive samples were inoculated into Vero cells for viral culture.After three consecutive blind passage,samples with cytopathic effect(CPE)were collected for be sequencingand analysisof genetic and evolutionary information.Dengue case characteristics were analyzed through descriptive epidemiological methods.Among the 109 cases of dengue fever,the ratio of males to females was 1.27∶1.The youngest patient was 1 year old,the oldest patient was 84 years old,the age group of 20～59 years accounted for 73.39%,and the major-ity of occupations were freelancer(40.37%).A total of 827 female Aedes albopictus and 312 Aedes aegypti were collected,all of which tested negative for DENV nucleic acid.109 serum samples tested positive for DENV nucleic acid,including 49 DENV-1 and 60 DENV-2.Moreover,five DENV-1 and nine DENV-2 samples were obtainedthrough third-generation blind passaging with CPE.The E gene sequences of these five DENV-1 strains were detected,all were found to belong to DENV-1 genotype I,and had same evolu-tionary branch as the 2023 Guangzhou,China(PP563911),the 2019 Myanmar(MW793710),and 2019 Attapeu,Laos(MW559046).The nucleotide and amino acid sequence similarityamong the five DENV-1 genotype was 99.4%-99.9%and 99.8%-100.0%.Compared with the aforementioned epidemic strains,their nucleotide similarities were 99.5%-100.0%,99.4%-99.6%and 99.3%-99.5%,respec-tively,and amino acid similarity was 99.8%-100.0%.Nine DENV-2 E gene sequences were of Asian genotype I and belonged to the same evolutionary branch as the 2018 Myanmar(MW788982),2019 Hangzhou(OP684212)and 2019 Ruili(OQ928150).The nucleotide and amino acid similarities of the nine samples were 99.5%-100.0%and 99.8%-100.0%,respectively.Compared with the aforementioned epidemic strains,their nucleotide similarities were 99.7%-100.0%,99.3%-99.7%and 99.3%-99.7%,respectively,and the amino acid similarity was 99.8%-100%,99.8%-100.0%and 99.4%-99.6%,respectively.Two dengue vectors,Aedes albopictus and Aedes aegypti,were present in Ruili city,and the dengue outbreak was caused primarily by DENV-1 genotype I and DENV-2 Asian genotype I in later 2023.The sources of DENV-1 were probably the same as those of DENV-1 with Guangzhou(2023),and the sources of DENV-2 were probably from Myanmar.Dengue cases were found primarilyin the 20-59 year age group and freelancers,thus suggesting that relevant local departments should strengthen surveillance of dengue imported case and vector.

BACKGROUND:The utilization of miniscrews for assisting in molar distalization with clear aligners is a commonly adopted clinical approach.However,treatment outcomes may be influenced by the implantation position of miniscrew and the hooks in various tooth location.OBJECTIVE:To analyze the biomechanical effects of hooks at different tooth positions and the assistance of buccal and palatal miniscrews in distalizing molars with clear aligners by using the finite element method.METHODS:By integrating volunteer cone beam CT and Itero intraoral scan data,high-precision finite element models were constructed to simulate the combined use of miniscrews and hooks to assist in the distalization of the maxillary first and second molars with clear aligners,aiming for a designed distalization magnitude of 0.2 mm.Four conditions were established based on the placement of buccal or palatal miniscrews,as well as the located of hooks at the canine or first premolar.The buccal anchorage screw was used in combination with hooks on the buccal side of the canine;the buccal anchorage screw was used in combination with hooks on the buccal side of the first premolar;the palatal anchorage screw was used in combination with hooks on the lingual side of the canine,and the palatal anchorage screw was used in combination with hooks on the lingual side of the first premolar.Analysis using ANSYS software was conducted to evaluate the three-dimensional displacement trends of maxillary teeth and the maximum equivalent stress on the periodontal ligament under each condition.RESULTS AND CONCLUSION:(1)Regardless of whether hooks were placed on canines or first premolars,palatal miniscrews had been shown to enhance the distal movement of maxillary molars and reduce the mesial movement of premolars as well as the labial tipping tendency of anterior teeth,compared to buccal miniscrews.The maximum equivalent stress in the periodontal ligament of molars was increased,while that of anterior teeth was decreased.(2)Regardless of whether the miniscrews were located on the buccal or palatal side,compared with hooks at the first premolar,when hooks were done at the canine,the labial inclination trend of the anterior teeth was reduced,the distal movement of the molars was reduced,the mesial movement of the premolars was increased,and the maximum equivalent stress of the molar and the periodontal membrane of the anterior teeth was reduced.(3)Regardless of whether miniscrews were located on the buccal or palatal side,and the hooks were located on the canine or the first premolar,the molar could not achieve overall movement.(4)The results show that clear aligner combined with palatal miniscrews and hooks at the first premolar are more conducive to improving the efficiency of maxillary molar distalization,but attention should be paid to protecting the anterior tooth miniscrews and molar torque control;clear aligner combined with palatal miniscrews and hooks at the canine is more conducive to reducing the labial tipping tendency of anterior teeth,but the efficiency of molar distalization will be relatively reduced.

Objective To clone the glycosyltransferase gene UGT708Z1 in Anemarrhena asphodeloides and perform its bioinformatics analysis,prokaryotic expression analysis and functional characterization.Methods A candidate glycosyltransferase gene UGT708Z1 was mined and screened out from Anemarrhena asphodeloides based on the transcriptome data.According to its full-length open reading frame,the specific primers with homologous arms were designed.Subsequently,the UGT708Z1 gene was cloned by PCR.The prokaryotic expression recombinant vector pET-32a(+)-UGT708Z1 was constructed through homologous recombination technology,and the soluble target protein was obtained by prokaryotic expression and purified protein technology.Finally,the function of UGT708Z1 was identified through enzymatic reaction in vitro.Results Sequence analysis showed that the open reading frame of UGT708Z1 was 1377 bp,encoding 458 amino acids.The result of prokaryotic expression showed that UGT708Z1 successfully expressed the soluble target protein,and the purified recombinant protein was 70.86 kDa.The results of enzymatic reaction in vitro showed that UGT708Z1 had flavonoid 7-OH glycosylation activity and could catalyze icaritin to produce icariside I.In addition,UGT708Z1 also possessed the activities of catalyzing the 7-O-glycosylation of quercetin and apigenin.Conclusion In this study,a flavonol glycosyltransferase UGT708Z1 was successfully cloned and identified from Anemarrhena asphodeloides,which would lay a foundation for further analysis of flavonol glycosides biosynthesis.

Breast cancer， as one of the major cancers threatening women's health globally， is characterized by high aggressiveness， high malignancy， and poor prognosis. In 2022， according to the World Health Organization， breast cancer ranked second in the incidence of female cancers globally， accounting for 11.6% of all new cancer cases. Western medical doctors mainly use surgery， chemotherapy， radiotherapy， endocrine therapy， and molecular targeted therapy to treat breast cancer， which can effectively improve the recurrence rate and death rate of breast cancer patients and prolong the survival period of patients. However， its treatment process is often accompanied by a series of side effects， which bring challenges to patients' quality of life. However， traditional Chinese medicine （TCM） has demonstrated significant therapeutic effects in inhibiting the proliferation and metastasis of breast cancer cells， reducing toxic side effects produced by chemotherapy， and improving patients' survival rate and quality of life. It is therefore particularly necessary to investigate the pharmacological effects and mechanisms of TCM in breast cancer treatment. The authors combed the pharmacological effects and mechanisms of the etiology and pathogenesis of breast cancer， identification and treatment of breast cancer， TCM compound， TCM single medicine， TCM monomer， and external treatment of TCM to prevent and control breast cancer and found that TCM has a therapeutic effect on breast cancer. It can play a role in increasing the effectiveness， reducing the toxicity， and alleviating the adverse reactions. It can inhibit breast cancer cell proliferation， cell cycle， migration， invasion， immune escape， epithelial-mesenchymal transition （EMT）， aerobic glycolysis， mitochondrial biosynthesis， aminoacyl-tRNA biosynthesis， reduce drug resistance， promote apoptosis， ferroptosis， cell autophagy， and regulate the tumor immune microenvironment by regulating signaling pathways. This paper aims to provide new ideas and methods for experimental research and clinical treatment of breast cancer.

Lung cancer has the highest morbidity and mortality rate among all cancers. Because of the complex pathogenesis， there are limitations in the common Western medicine treatment methods. Clinical and experimental studies have proved that traditional Chinese medicine （TCM） can not only effectively treat lung cancer and alleviate the clinical symptoms of cancer patients but also reduce the adverse reactions and complications caused by surgery， chemotherapy， and radiotherapy to improve the quality of life of the patients. The biological behaviors of lung cancer cells， such as proliferation， invasion， and metastasis， are closely related to their metabolic reprogramming. Metabolic reprogramming in lung cancer involves a series of metabolic changes such as increased glucose uptake and consumption， enhanced glycolysis， increased amino acid uptake and catabolism， and enhanced lipid and protein synthesis. Studies have reported that TCM active components， extracts， and compound prescriptions can effectively inhibit the biological behaviors of lung cancer by regulating metabolic reprogramming. Therefore， this paper reviews the pharmacological mechanisms of TCM active components， extracts， and compound prescriptions in regulating metabolic reprogramming of lung cancer， with the aim of providing a new way of thinking for the treatment of lung cancer by TCM regulation of metabolic reprogramming of lung cancer cells. The available studies suggest that TCM mainly inhibits the extracellular signal-regulated protein kinase （ERK）/c-Myc， phosphatidylinositol 3-kinase （PI3K）/protein kinase B （Akt）/mammalian target of rapamycin （mTOR）， and hypoxia-inducible factor-α （HIF-1α） pathways. Furthermore， the expression of monocarboxylate transporter 4 （MCT4）， glucose transporter 1 （GLUT1）， pyruvate dehydrogenase （PDH）， phosphofructokinase 1 （PFK1）， pyruvate dehydrogenase kinase 1 （PDK1）， pyruvate kinase M2 （PKM2）， hexokinase （HK）， lactate dehydrogenase （LDH）， and lactate dehydrogenase A （LDHA） are inhibited. In this way， TCM inhibits the glucose uptake by lung cancer cells and glycolysis in lung cancer cells to reduce the energy metabolism of tumor cells， ultimately achieving the therapeutic effect on lung cancer.
