This paper comprehensively discusses on the potential neurobiological mechanisms of acupuncture in the treatment of tobacco dependence， focusing on three important aspects， including acupuncture's regulation of tobacco dependence behavior， effects of acupuncture on withdrawal syndrome， and the role of acupuncture in preventing relapse. It is found that acupuncture can inhibit drug-seeking behavior by regulating the reward pathway and related neurons， such as dopamine， thus modulating tobacco dependence behavior. It also alleviates withdrawal symptoms by improving the oral environment of smokers and reducing negative emotions after quitting. Furthermore， acupuncture can prevent relapse by decreasing brain network activity related to smoking cravings and improving cognitive brain functions like addiction memory. Currently， research on the specific neurobiological mechanism of acupuncture in treating tobacco dependence and the involved neural circuits is limited. Future research directions are proposed， including the evaluation of clinical effects， exploration of specific therapeutic mechanisms， investigation of brain pathology， and strengthening the exploration of brain functions. Additionally， combining modern technologies to clarify the neural circuits involved in acupuncture intervention will provide a basis for acupuncture treatment of tobacco addiction.

Colorectal cancer （CRC） is a prevalent malignant tumor of the digestive tract， with a high incidence and high mortality. The majority of patients are diagnosed at the middle or advanced stage， which severely influences and threatens their physical health. Current treatment modalities such as surgery， radiotherapy， and chemotherapy often encounter challenges including metastasis， recurrence， and drug resistance. The phosphatidylinositol 3-kinase （PI3K）/protein kinase B （Akt）/mammalian target of rapamycin （mTOR） signaling pathway serves as a classical regulator that regulates physiological processes such as cell cycle， autophagy， apoptosis， and proliferation. Overexpression of this pathway is observed in various tumors. In the context of CRC， the activation of this pathway can facilitate the proliferation， invasion， and migration， inhibit the autophagy and apoptosis， promote the epithelial-mesenchymal transition of CRC cells， enhance angiogenesis within the tumor， and contribute to chemotherapy resistance and radiation resistance in CRC. Traditional Chinese medicine （TCM） treatment can exert an anti-CRC effect by inhibiting this pathway， thereby improving clinical efficacy and safety. This article retrieves relevant research literature published domestically and internationally regarding the regulation of the PI3K/Akt/mTOR signaling pathway by TCM in the treatment of CRC and conducts detailed classification and summary. The active components of TCM include glycosides， flavonoids， alkaloids， terpenoids， polyphenols， and naphthoquinones. The volatile oils and extracts of TCM include Angelicae Sinensis Radix volatile oil， Astragali Radix polysaccharides， Caryophylli Flos extract， Forsythiae Fructus extract， Curcumae Longae Rhizoma extract， and Celastrus orbiculatus extract. The compound formulas of TCM include Banxia Xiexin decoction， Jianpi Qingre Huoxue formula， and Chanling Plaster. Through summary and analysis， it is discovered that the abovementioned TCM can produce effects such as blocking the cell cycle， inducing autophagy and apoptosis， inhibiting angiogenesis， suppressing proliferation and migration， and reversing chemotherapy resistance and radiotherapy resistance by inhibiting the PI3K/Akt/mTOR pathway in CRC cells. TCM holds promise in the research and application of targeting the PI3K/Akt/mTOR signaling pathway for CRC treatment. The summary and conclusion of this article aim to provide references for subsequent research and the development of new drugs.

Multiple myeloma (MM) is a hematological malignancy that poses significant treatment challenges due to its heterogeneity and propensity for relapse and progression. In the last two decades, the therapeutic landscape of MM has changed dramatically, but the disease remains largely incurable, with many patients facing treatment resistance. This review evaluates the current status of MM treatments, emphasizing the limitations of traditional therapies and the emerging role of immunotherapy in improving patient outcomes. It highlights the importance of achieving and maintaining minimal residual disease negativity and a balanced immune response as key treatment goals. Furthermore, it discusses the advancements in immunotherapies that are improving the prospects for patients, particularly those with relapsed or refractory disease. Innovative strategies, such as chimeric antigen receptor T-cell therapy, bispecific antibodies, and bispecific T cell engagers, have shown significant promise by targeting the malignant cells and the bone marrow microenvironment, which are essential for disease persistence and resistance to therapy. Future research should focus on refining MM treatment strategies, including the integration of immunotherapy into earlier treatment lines and the development of predictive biomarkers for personalized treatment approaches, ultimately enhancing patient outcomes.

Dendrobium moniliforme (D. moniliforme) is a traditional medicinal herb widely cultivated in Asia. Flavonoids, one of the largest groups of secondary metabolites in plants, are significant medicinal components in Dendrobium species. Several subgroups of R2R3-MYB proteins have been validated to directly regulate flavonoid biosynthesis. Using PacBio sequencing technology, we assembled a high-quality chromosome-level D. moniliforme genome with a total length of 1.20 Gb and a contig N50 of 3.97 Mb. The BUSCO assessment of genome annotation was 91.4%. By integrating the genome and transcriptome, we identified biosynthesis pathway enzyme genes related to flavonoids, polysaccharides, carotenoids, and alkaloids. A total of 90 R2R3-MYBs were identified in D. moniliforme and classified into 21 subgroups. Studies on the functions of R2R3-MYB transcription factors revealed that R2R3-MYB in SG6 can up-regulate flavonoid biosynthesis. Various validation experiments, including subcellular localization, transient overexpression, UPLC-MS/MS, HPLC, yeast one-hybrid, and dual-luciferase assays, demonstrated that DMYB69 directly up-regulates the expression of enzyme genes involved in flavonoid biosynthesis, increasing the content of flavonoids such as anthocyanin, flavone, and flavonol. Additionally, DMYB44 was shown to directly up-regulate the expression of carotenoid biosynthesis enzyme genes, thereby increasing carotenoid content. This study provides an essential genome resource and theoretical basis for molecular breeding research in D. moniliforme.

Objective:To develop a standardized training model incorporating feedback from a digital assessment tool and to evaluate whether the model provides effective training in tooth preparation.Methods:The study was based on the training data of 53 trainees enrolled between February and June 2018 from multiple institutions in China. The trainees were trained in a standardized training unit on the preparation of right maxillary mesial incisors (11 #) for metal ceramic crowns. Three sessions of practice-assessment-feedback before examination were performed in one day. A digital assessment system was used to obtain total and component scores for the preparation as indicators of observation. The scores of three practice sessions and examination were subjected to analysis of variance. Results:The mean total scores before training, after the first training session, after the second training session, after the third training session, and in the examination were (60.53±12.73), (60.12±12.98), (71.25±13.70), (70.70±11.84), and (69.67±12.85), respectively; the overall difference was statistically significant ( F=19.06, P<0.001). Compared to the total scores before training and after the first training session, the total scores after the second and third training sessions and in the examination were significantly increased ( P<0.001, P<0.001). The score deductions for cutting amount and shoulder were similar, with overall significant differences (score deductions for cutting amount, F=16.20, P<0.001; score deductions for shoulder, F=1.45, P=0.032). Compared to before training and after the first training session, the second and third training sessions and the examination showed significant decreases in score deductions for cutting amount and shoulder ( P<0.001, P=0.048). Conclusions:The feedback-based standardized training process established on a digital evaluation system can rapidly enhance the skills of dentists in tooth preparation through immediate and effective feedback and targeted improvements. The training process enables an independent practice mode and optimizes teaching outcomes.

Objective To investigate the value of electrocardiogra(ECG)P-wave parameters com-bined with serum adiponectin and visfatin(VF)in predicting recurrence of atrial fibrillation(AF)after radiofrequency ablation.Methods A total of 120 AF patients(AF group)admitted to our hospital from March 2021 to March 2023 were enrolled,and divided into a recurrence group(39 cases)and a non-recurrence group(81 cases)according to the postoperative condition.Another 120 healthy individuals who took physical examination in the same period were enrolled and served as control group.All subjects underwent ECG.ELISA was used to detect adiponectin and VF levels.Logistic regression analysis was used to identify the influencing factors of postoperative recur-rence in AF patients.ROC curve was plotted to analyze the predictive value of P-wave parameters combined with serum adiponectin and VF for postoperative recurrence in AF patients.The P-wave parameters included P-wave duration(PWD),maximum PWD(Pmax),minimum PWD,and P-wave dispersion(Pd).Results PWD,Pmax and Pd were significantly decreased in AF patients after operation(P＜0.01).Serum adiponectin level was obviously lower and that of VF was nota-bly higher in the AF group than the control group(6.15±1.58 μg/L vs 11.43±2.26 μg/L,12.05±2.30 μg/L vs 6.23±1.02 μg/L,P＜0.01).The recurrence group had remarkably higher preopera-tive PWD,Pmax and Pd,and lower adiponectin and higher VF levels than the non-recurrence group(P＜0.01).Multivariate logistic regression analysis showed that PWD,Pmax,Pd,and VF were risk factors,and adiponectin was a protective factor for postoperative recurrence in AF pa-tients(P＜0.05,P＜0.01).ROC curve analysis indicated that PWD,Pmax,Pd,adiponectin and VF combined together to detect postoperative recurrence in AF patients had an AUC value of 0.972,which was higher than that of above indicators alone(Z=2.574,Z=2.567,Z=2.543,Z=2.554,Z=2.586,P＜0.05).Conclusion ECG P-wave parameters as well as elevated serum VF and re-duced serum adiponectin are influencing factors for postoperative recurrence in AF patients,and their combined detection may promote the predictive value for postoperative recurrence in them.

Pathogenesis and treatment methods of qi-ying fen transformation in warm diseases are explored.It is believed that warm diseases are caused by yang pathogenic factors and are most likely to damage the organs and body fluids.Body fluids,as important components of human body's healthy qi,are usually present in the lungs as lung fluids,in the stomach as stomach fluids,in the intes-tines as intestinal fluids,and in blood vessels as nutrient yin.During the transformation from qi fen syndrome to ying fen syndrome,vis-ceral parenchymal damage acts as its important pathological mechanism and fluid depletion in blood vessels is an important reason for exacerbating qi-ying fen transformation.Excessive fire-toxicity,as an initial factor,promotes qi-ying fen transformation.Fluid deple-tion is the pathological basis for exacerbating qi-ying fen transformation.Clearing heat and protecting fluids,with sweet-flavored and cold-natured drugs to generate fluids,salty-flavored and cold-natured drugs to clear heat,and combination of sweet-flavored and bit-ter-flavored drugs,is an inevitable treatment method for preventing and treating qi-ying fen transformation in warm diseases,and it al-so has important clinical guidance value for internal miscellaneous diseases and acute severe cases.
