Obesity， a global chronic disease， is associated with adipose tissue dysfunction， which is one of the contributing factors to obesity. The cyclic adenosine monophosphate （cAMP） signaling pathway， a key regulator of lipid metabolism， plays a pivotal role in obesity development. Various of traditional Chinese medicine monomers， such as flavonoids， lignans， phenols， and terpenoids， as well as traditional Chinese medicine compound formulas like Xiaoyao powder， Shengmai powder， and Zexie decoction， can maintain energy homeostasis， balance adipose tissue function， regulate glucose metabolism， improve insulin resistance， and suppress inflammatory responses through cAMP signaling pathway regulation， thereby intervening in lipid metabolism for obesity treatment. Although a substantial amount of basic research has preliminarily elucidated the potential mechanisms by which traditional Chinese medicine intervenes in obesity through the cAMP signaling pathway， clinical translational research remains inadequate. There is an urgent need for large-sample， high-quality randomized controlled trials to validate these findings.

Pancreatic cancer is a highly malignant solid tumor of the digestive system with extremely poor treatment prognosis. Although its incidence rate is low， its mortality rate is extremely high. In recent years， the number of diagnosed cases worldwide has continued to rise， making pancreatic cancer the sixth leading cause of cancer-related deaths globally. Currently， clinical treatment primarily relies on operation and chemotherapy to suppress tumors. However， these approaches face challenges such as suboptimal efficacy， high postoperative recurrence rates， and severe adverse reactions. Therefore， identifying safe and effective treatment modalities remains a pressing challenge for the medical community. In recent years， research on traditional Chinese medicine （TCM） interventions for pancreatic cancer has increased significantly. Multiple studies have shown that single-herb TCM， TCM formulas， and their derived single compounds can regulate the levels of tumor cell signaling pathways through multiple action targets. They inhibit the development and progression of pancreatic cancer by inhibiting cancer cell proliferation， promoting cell apoptosis， inhibiting tumor angiogenesis， reducing cancer cell invasion and migration capabilities， regulating the cell cycle， and modulating the tumor microenvironment. Additionally， TCM has the advantages of significantly enhancing the anticancer efficacy of chemotherapy drugs and causing fewer adverse reactions. However， the specific action mechanisms by which TCM intervenes in pancreatic cancer remain unclear. Further extensive research is still needed to validate the role of regulating classical signaling pathways such as phosphoinositide 3-kinase （PI3K）/protein kinase B （Akt）/mammalian target of rapamycin （mTOR）， Wnt/β-catenin， nuclear transcription factor-κB （NF-κB）， notch， and hedgehog in the treatment of pancreatic cancer. Therefore， this paper reviewed Chinese and international studies on TCM intervention in pancreatic cancer through relevant signaling pathways in recent years， summarized the potential action mechanisms of TCM in the treatment of pancreatic cancer， and provided references for related research in the future.

Objective To explore the role of clinical pharmacists in the treatment of advanced breast cancer patients with severe myelosuppression.Methods This case report describes the diagnostic and therapeutic process of an advanced breast cancer patient who developed severe myelosuppression after applying ADC-based drug therapy.The clinical pharmacist proposed a prophylactic antimicrobial drug selection plan and medication monitoring recommendations for the patient's granulocytopenic fever after assessing the risk of infection and liver and renal function.For oncology drug-associated thrombocytopenia,when the doctor proposed to use the recombinant human thrombopoietin combined with TPO agonists in the case of the ineffectiveness of conventional treatment,the clinical pharmacist searched for the pharmacological basis of the combination regimen,the clinical studies of the efficacy and the adverse reactions to assist the physician's decision-making and provided targeted medication monitoring of the patient.Results The clinician and clinical pharmacist developed and implemented a rational treatment plan,and the patient was discharged with improvement.Conclusions Clinical pharmacists can assist physicians in optimizing individualized treatment plans through pharmacological monitoring of advanced breast cancer patients with severe myelosuppression.This collaborative treatment model can provide patients with more individualized treatment;it can also provide clinical reference to the treatments of patients with severe myelosuppression.

Objective:To construct a continuity of care plan for adolescent fixed orthodontic patients based on the theory of timing, and provide systematic and standardized nursing interventions for adolescent fixed orthodontic patients.Methods:Guided by the theory of timing, preliminary plan items were formulated through literature review and questionnaire survey. Using the Delphi method, 15 experts were consulted for two rounds to determine the continuity of care plan for adolescent fixed orthodontic patients from October to December, 2023.Results:The effective response rates of the two rounds of questionnaires were 15/15, respectively. The expert authority levels were 0.93 and 0.94, and the Kendall harmony coefficients were 0.28 and 0.38, respectively. The differences were statistically significant (both P<0.001). The final established plan included 5 primary indicators, 23 secondary indicators, and 47 tertiary indicators. Conclusions:The continuity of care plan for adolescent fixed orthodontic patients based on the timing theory is reliable and scientific, and can meet the continuity of care needs of patients at different stages, providing reliable clinical basis for carrying out continuity of care.

Objective:To assess the safety and efficacy of thiotepa, busulfan, and etoposide (TBE) conditioning followed by autologous hematopoietic stem-cell transplantation (TBE auto-HSCT) in primary central nervous system lymphoma (PCNSL) patients.Methods:Clinical data from 27 PCNSL patients who received TBE auto-HSCT at the Fifth Medical Center of PLA General Hospital between November 1, 2021, and April 30, 2024, were retrospectively analyzed.Results:Twenty-seven patients [16 males, 11 females; median age 57 (23–72) years] were included, with 12 (44.4%, 12/27) over 60. Twenty-five had newly diagnosed PCNSL and 2 were relapsed. Median time from diagnosis to transplantation was 6.9 (5.0–10.0) months. TBE auto-HSCT increased complete remission (CR) rate from 63.0 to 96.3% ( P= 0.005), and 9 of 10 patients in partial remission achieving CR post-transplant. Median follow-up was 24.5 months (range 2.0–36.0). Two-year progress-free and OS rates were (87.2±6.9) % and (88.6±6.2) %, respectively. Common grade 3 nonhematologic adverse events were diarrhea (18.5%, 5/27) and bacterial infections (14.8%, 4/27). One patient (64 years old) died from carbapenem-resistant Enterobacteriaceae infection within 2 months post-transplant, yielding a 100-day treatment-related mortality of 3.7% (1/27) . Conclusion:TBE-conditioned high-dose chemotherapy with auto-HSCT is effective, safe, and well-tolerated in PCNSL patients, including the elderly.
