As the pace of society increases and lifestyles change, the incidence and mortality rates of breast cancer continue to rise. Targeted therapies are now promising in the treatment of breast cancer, and a variety of protein targets have been identified to play an important role in the development of breast cancer. Among them, signal transducer and activator of transcription (STAT) proteins constitute a crucial group that serves as important targets for transducing cellular transcriptional information, which can regulate downstream cell proliferation, apoptosis, cell migration, invasion, angiogenic factors, etc. and then affect the progression of breast cancer. The STAT family is closely associated with the inflammatory response to tumors and plays a landmark role in tumor development as well as in diagnosis and prognosis. The "inflammation-cancer" transformation refers to the process in which the inflammatory microenvironment caused by uncontrolled inflammation promotes normal cells to become cancerous. According to the theory of Chinese medicine, "heat toxicity" in "cancer toxicity" corresponds to inflammation, which is closely related to tumor development. As a major link associated with the inflammatory response, the STAT family has a promising role in the development and treatment of a variety of tumors, but its relevance to breast cancer remains inadequately explored. Chinese medicine has been shown to have good efficacy in the prevention and treatment of breast cancer, and some current studies have shown that the active ingredients and compounds of Chinese medicine have certain intervention effects on breast cancer-related STAT proteins, but there has not been a systematic review. In order to better sort out and summarize the studies on the effects of Chinese herbal medicines based on the STAT family interventions in breast cancer, this paper reviewed the studies on Chinese herbal medicines acting on the STAT family in recent years, aiming to provide new ideas for clinical applications in breast cancer and to provide thoughts for the development of STAT protein-based drugs.

ObjectiveTo observe the clinical effectiveness and safety of Hewei Anshen Formula (和胃安神方) for stress-induced insomnia. MethodsA total of 104 male patients with stress-induced insomnia were randomly divided into a treatment group and a control group, with 52 cases in each group. The treatment group was given Hewei Anshen Formula once a day, while the control group was given zolpidem tartrate tablets 10 mg per time and once a day, and both groups were treated for 4 weeks. The Pittsburgh Sleep Quality Index (PSQI) was applied to evaluate sleep quality before and after treatment, Ford Insomnia Response to Stress Test (FIRST) was used to evaluate insomnia susceptibility, MOS 36-tem Short Form Health Survey (SF-36) [which includes the domains of Physical Component Summary (PCS) and Mental Health Component Summary (MCS), with the PCS including the General Health (GH), Physical Functioning (PF), Role Physical (RP), and Body Pain (BP), and the MCS including Role Emotional (RE), Social Functioning (SF), Vitality (VT), Mental Health (MH)] was used to evaluate the quality of life, and Fatigue Scale 14 (FS-14) [including somatic fatigue and brain fatigue scores] to evaluate the degree of fatigue, and the traditional Chinese medicine (TCM) syndrome scores using a self-developed TCM syndrome survey for insomnia. Clinical effectiveness and TCM syndrome improvement were determined after treatment. The occurrence of adverse events and adverse reactions was recorded during treatment. ResultsThe total effective rate of clinical effectiveness was 90.38% (41/52) in the treatment group and 80.77% (42/52) in the control group, and the difference between the two groups was not statistically significant (P>0.05). The total effective rate of TCM syndrome effectiveness in the treatment group was 80.77% (42/52), which was higher than 44.23% (23/52) in the control group, and the difference was statistically significant (P<0.01). The TCM syndrome score, FIRST score, brain fatigue scores, brain fatigue score and total score of FS-14 score all reduced after treatment in both groups, and all scores were lower in the treatment group than those in the control group after treatment (P<0.05). All transformed scores of SF-36 scores were higher in both groups after treatment than before treatment in this group, and they were better than the control group in the four dimensions of PF, RP, VT, and MH (P<0.05). There were no adverse events and adverse reactions in the two groups. ConclusionHewei Anshen Formula can improve patients' sleep quality, effectively relieve clinical symptoms such as fatigue and pain, alleviate TCM syndromes, enhance the quality of life, reduce the susceptibility to insomnia, and shows good safety.

Data analysis models may assist the transmission of traditional Chinese medicine (TCM) experience and clinical diagnosis and treatment, and the possibility of constructing a “data-knowledge” dual-drive model was explored by taking gastric precancerous state as an example. Data-driven is to make clinical decisions around data analysis, and its syndrome-differentiation decision-making research relies on hidden structural models and partially observable Markov decision-making processes to identify the etiology of diseases, syndrome elements, evolution of pathogenesis, and syndrome differentiation protocols; knowledge-driven is to make use of data and information to promote decision-making and action processes, and its syndrome-differentiation decision-making research relies on convolutional neural networks to improve the accuracy of local disease identification and syndrome differentiation. The “data-knowledge” dual-driven model can make up for the shortcomings of single-drive numerical simulation accuracy, and achieve a balance between local disease identification and macroscopic syndrome differentiation. On the basis of previous research, we explored the construction method of diagnostic assisted decision-making platform for gastric precancerous state, and believed that the diagnostic and decision-making ability of doctors can be extended through the assistance of machines and algorithms. Meanwhile, the related research methods were integrated and the core features of gastric precancerous state based on TCM syndrome differentiation and endoscopic pathology diagnosis and prediction were obtained, and the elements of endoscopic pathology recognition based on TCM syndrome differentiation were explored, so as to provide ideas for the in-depth research and innovative application of cutting-edge data analysis technology in the field of intelligent TCM syndrome differentiation.

ObjectiveTo investigate the possible mechanism of Hewei Anshen Formula (和胃安神方) in the treatment of insomnia. MethodsSixty male SD rats were randomly divided into the normal group, the model group, the eszopiclone group and the low-, medium- and high-dose Hewei Anshen Formula groups. The insomnia model was constructed by intraperitoneal injection of p-chlorophenylalanine (PCPA) for 2 days in all groups except the normal group. After successful modelling, the eszopiclone group was given 0.33 mg/(kg·d) eszopiclone aqueous solution by gavage, the low-, medium- and high-dose Hewei Anshen Formula groups were given 10 ml/kg of Hewei Anshen Formula with a concentration of 1, 2 and 4 g/ml, respectively, and the rats in the normal group and the model group were given 10 ml/kg of saline by gavage, once a day for 7 consecutive days. The general condition of the rats was observed during the experiment, and the body mass of the rats was measured every day after medication administration. The following day after the last medication administration, pentobarbital sodium co-test was used to observe the sleep condition, and the sleep latency and sleep duration were recorded; immunohistochemistry and Western blot were used to detect the expression of hypothalamic clock rhythm regulating protein (CLOCK) and brain and muscle aromatic hydrocarbon receptor nuclear transporter-like protein 1 (BMAL1) in the rats. ResultsThe body mass of rats in the model group was lower than that of rats in the normal group at all time points (P<0.01); compared with the same time in the eszopiclone group, the body mass of rats in the low-dose Hewei Anshen Formula group was elevated on the 5th, 6th and 7th days of medication administration (P<0.05). Compared with the normal group, the sleep duration of rats in the model group was shortened (P<0.01); compared with the model group, the sleep duration of rats in each dosage group increased (P<0.01), and the difference between the high-dose Hewei Anshen Formula group and the eszopiclone group showed no statistically significant (P>0.05), while the sleep duration of the low- and medium-dose Hewei Anshen Formula groups were shorterned than the eszopiclone group (P<0.01). The difference in sleep latency showed no statistically significant among each group (P>0.05). The results of both immunohistochemistry and Western blotting showed that the expression of CLOCK and BMAL1 in the hypothalamus of rats in the model group was significantly reduced compared with that in the normal group (P<0.01); the expression of CLOCK and BMAL1 in the hypothalamus of rats in the low- and high-dose Hewei Anshen Formula groups increased than that in the model group (P<0.05 or P<0.01). ConclusionHewei Anshen Formula can improve insomnia in model rats, and its mechanism of action may be related to the up-regulation of the expression of the hypothalamic biological clock genes CLOCK and BMAL1 protein.

Uncovering the risk factors of pulmonary hypertension and its mechanisms is crucial for the prevention and treatment of the disease.In the current study,we showed that experimental periodontitis,which was established by ligation of molars followed by orally smearing subgingival plaques from patients with periodontitis,exacerbated hypoxia-induced pulmonary hypertension in mice.Mechanistically,periodontitis dysregulated the pulmonary microbiota by promoting ectopic colonization and enrichment of oral bacteria in the lungs,contributing to pulmonary infiltration of interferon gamma positive(IFNγ+)T cells and aggravating the progression of pulmonary hypertension.In addition,we identified Prevotella zoogleoformans as the critical periodontitis-associated bacterium driving the exacerbation of pulmonary hypertension by periodontitis,and the exacerbation was potently ameliorated by both cervical lymph node excision and IFNγ neutralizing antibodies.Our study suggests a proof of concept that the combined prevention and treatment of periodontitis and pulmonary hypertension are necessary.

N1-methyladenosine(m1A)RNA methylation is critical for regulating mRNA translation;however,its role in the development,progression,and immunotherapy response of head and neck squamous cell carcinoma(HNSCC)remains largely unknown.Using Tgfbr1 and Pten conditional knockout(2cKO)mice,we found the neoplastic transformation of oral mucosa was accompanied by increased m1A modification levels.Analysis of m1A-associated genes identified TRMT61A as a key m1A writer linked to cancer progression and poor prognosis.Mechanistically,TRMT61A-mediated tRNA-m1A modification promotes MYC protein synthesis,upregulating programmed death-ligand 1(PD-L1)expression.Moreover,m1A modification levels were also elevated in tumors treated with oncolytic herpes simplex virus(oHSV),contributing to reactive PD-L1 upregulation.Therapeutic m1A inhibition sustained oHSV-induced antitumor immunity and reduced tumor growth,representing a promising strategy to alleviate resistance.These findings indicate that m1A inhibition can prevent immune escape after oHSV therapy by reducing PD-L1 expression,providing a mutually reinforcing combination immunotherapy approach.

Objective To investigate whether Heshouwuyin can delay the aging of Leydig cells in rat testis through DNA methyltransferase 1(DNMT1).Methods Totally 40 male Wistar rats were randomly divided into 4 groups,with 10 rats in each group.Immunohistochemistry was used to detect the expression levels of DNMT1 in testis tissue of rats.Testosterone content in serum of rats in each group was detected by ELISA test.A rat Leydig cell aging model was established by free radical oxidative damage.DNMT1 was knocked down by lentivirus in Leydig cells,and the cell senescence status and the testosterone content and testosterone synthesis key enzyme 3β-hydroxysteroid dehydrogenase(3β-HSD),cytochrome P450 family member 11A1(CYP11A1)content secreted by cells were detected by β-galactosidase(β-GAL)staining,immunofluorescenct staining and ELISA.Results Compared with the young control group(YCG),the expression of P16 protein and the positive rate of β-GAL in the testis tissue of rats in the natural aging group(NAG)increased significantly,and the expression of DNMT1 and serum testosterone levels decreased(P<0.05).However,after Heshouwuyin intervention,the expression of P16 protein and the positive rate of β-GAL in the testis of aging rats were reduced,and DNMT1 expression and the serum testosterone levels increased(P<0.05).The same trend was observed in Leydig cells.Knockdown of DNMT1 in Leydig cells,β-GAL positivity and P16 protein expression increased significantly,and testosterone secretion and testosterone synthesis key enzymes 3β-HSD,CYP11A1 content from Leydig cells decreased significantly,compared with the normal control group(NCG)(P<0.05).When Heshouwuyin was added,the above phenomenon was improved.Conclusion Heshouwuyin can delay the aging of rat Leydig cells through DNMT1.

Activation of nuclear factor erythroid 2-related factor 2(Nrf2)by Kelch-like ECH-associated protein 1(Keap1)alkylation plays a central role in anti-inflammatory therapy.However,activators of Nrf2 through alkylation of Keap1-Kelch domain have not been identified.Deoxynyboquinone(DNQ)is a natural small molecule discovered from marine actinomycetes.The current study was designed to investigate the anti-inflammatory effects and molecular mechanisms of DNQ via alkylation of Keap1.DNQ exhibited signif-icant anti-inflammatory properties both in vitro and in vivo.The pharmacophore responsible for the anti-inflammatory properties of DNQ was determined to be the α,β-unsaturated amides moieties by a chemical reaction between DNQ and N-acetylcysteine.DNQ exerted anti-inflammatory effects through activation of Nrf2/ARE pathway.Keap1 was demonstrated to be the direct target of DNQ and bound with DNQ through conjugate addition reaction involving alkylation.The specific alkylation site of DNQ on Keap1 for Nrf2 activation was elucidated with a synthesized probe in conjunction with liquid chromatography-tandem mass spectrometry.DNQ triggered the ubiquitination and subsequent degra-dation of Keap1 by alkylation of the cysteine residue 489(Cys489)on Keap1-Kelch domain,ultimately enabling the activation of Nrf2.Our findings revealed that DNQ exhibited potent anti-inflammatory capacity through α,β-unsaturated amides moieties active group which specifically activated Nrf2 signal pathway via alkylation/ubiquitination of Keap1-Kelch domain,suggesting the potential values of targeting Cys489 on Keap1-Kelch domain by DNQ-like small molecules in inflammatory therapies.
