ObjectiveTo explore the effects of Wumeiwan on liver metastasis and lung metastasis of colorectal cancer and its potential mechanism. MethodsFirstly, mice were randomized into control, low-dose (20 g·kg-1) Wumeiwan, high-dose (40 g·kg-1) Wumeiwan, and paclitaxel (10 mg·kg-1) groups. Secondly, liver metastasis and lung metastasis models of colorectal cancer were established in mice. After 4 weeks of intervention, the body weight of each mouse was recorded, and the lung weight, liver weight, and survival time of mice with metastatic colorectal cancer were determined. Hematoxylin-eosin (HE) staining was employed to detect the effects of Wumeiwan on liver metastasis and lung metastasis. Real-time PCR was employed to determine the mRNA levels of M1 and M2 macrophage markers in the liver tissue. Finally, the content of M1 macrophage markers CD80 and CD86 in the liver tissue was measured by flow cytometry. ResultsCompared with the control group, Wumeiwan and paclitaxel reduced the body weight (P<0.01) and liver weight (P<0.01) and prolonged the survival of the mouse model of liver metastasis of colorectal cancer (P<0.01). In the mouse model of lung metastasis of colorectal cancer, Wumeiwan and paclitaxel also reduced the body weight (P<0.01) and lung weight (P<0.01) and extended the survival time (P<0.01). Histopathological results showed that compared with the control group, Wumeiwan inhibited the liver and lung metastases of colorectal cancer. Real-time PCR results showed that compared with the control group, Wumeiwan upregulated the mRNA levels of M1 macrophage markers IL-1β, IL-6, tumor necrosis factor-α (TNF-α), inducible nitric oxide synthase (iNOS), and prostaglandin-endoperoxide synthase 2 (PTGS2) in the liver and lung tissue of mice with liver metastasis and lung metastasis of colorectal cancer (P<0.01). Meanwhile, Wumeiwan downregulated the mRNA levels of M2 macrophage markers Arg1, CD163, and CD206 (P<0.01). Meanwhile, the flow cytometry results showed that compared with the control group, Wumeiwan increased the content of CD86 and CD80 (P<0.01). In addition, immunohistochemical results showed that Wumeiwan promoted the expression of CD86 and inhibited the expression of CD206 in the liver and lung tissue of mice with liver metastasis and lung metastasis. ConclusionWumeiwan can inhibit the liver metastasis and lung metastasis of colorectal cancer by promoting the M1 polarization of macrophages in the liver and lung of the model mice.

OBJECTIVE To develop a method for the determination of tacrolimus (TAC) concentration in human whole blood and to apply it in clinical therapeutic drug monitoring. METHODS Whole blood samples were processed by protein precipitation with methanol. The determination was performed using liquid chromatography-tandem mass spectrometry (LC-MS/MS), with ascomycin serving as the internal standard. Chromatographic separation was carried out on a Kinetex F5 100Å column with a mobile phase consisting of 0.1 mmol/L ammonium acetate containing 0.2 mmol/L formic acid and methanol. Gradient elution was performed at a flow rate of 0.4 mL/min. The injection volume was 5 μL. Detection was conducted using multiple reaction monitoring ( m / z 821.6→768.6 for TAC; m / z 809.4→756.1 for ascomycin) with an electrospray ionization source in positive ion mode. The study focused on 86 whole blood samples collected from 83 pedi atric patients who received TAC therapy at Children’s Hospital of Nanjing Medical University from September 1 to 30, 2025. The aforementioned method was employed to measure the TAC concentration in the whole blood samples. The correlation and agreement between the aforementioned method and the traditional enzyme multiplied immunoassay technique (EMIT) were evaluated through Spearman correlation analysis, Bland-Altman analysis, and Passing-Bablok regression analysis. RESULTS The linear range of TAC was 0.5-100 ng/mL; the evaluation results for accuracy, precision, extraction recovery, matrix effect, and stability tests all met the relevant requirements. Clinical application results showed that the median concentration of TAC in pediatric whole blood measured by LC-MS/MS and EMIT methods were 4.4 and 4.0 ng/mL, respectively. Moreover, the two methods exhibited a strong correlation (correlation coefficient of 0.848 1) and good agreement (average relative deviation of 6.5%). CONCLUSIONS A reliable LC-MS/MS method for the determination of TAC concentration in human whole blood is successfully established. This method demonstrates strong correlation and good agreement with the EMIT method, making it suitable for clinical therapeutic drug monitoring.

The Compilation Instructions for Expert Consensus on Clinical Application of Dieda Huoxue capsules systematically expound the development methods and evidence-based basis of this consensus. In view of the weak clinical application evidence and ambiguous indications of Dieda Huoxue capsules, the Institute of Basic Research in Clinical Medicine of the China Academy of Chinese Medical Sciences and Wangjing Hospital took the lead and collaborated with 33 experts from 28 medical institutions nationwide. They strictly followed the World Health Organization (WHO) guideline-making norms and the Grading of Recommendations Assessment, Development and Evaluations (GRADE) evidence-grading system and completed the compilation through multidisciplinary cooperation. The workflow included constructing clinical questions (19 items were screened by the nominal group technique), retrieving evidence (from Chinese and English databases and grey literature), assessing safety (integrating drug monitoring data and clinical investigations), and forming recommendations and consensus suggestions (3 recommendations were reached via the GRADE grid method, and 16 consensus suggestions were reached by the majority vote rule). The results indicate that the consensus clearly states that this medicine (Dieda Huoxue capsules) is applicable to conditions like traumatic injury, blood stasis-induced pain, and sudden lumbar sprains. The recommended dose is 6 capsules each time, twice a day. Combining oral administration with external application can enhance the efficacy, and elderly patients should take the medicine at intervals. Safety monitoring suggests that it should be used with caution in people with a bleeding tendency and those with an allergic constitution. The compilation process involved three rounds of reviews by internal and external experts. Literature analysis, the Delphi method, and clinical applicability tests were employed to ensure methodological rigor. The compilation instructions comprehensively present key aspects such as project approval and registration, conflict-of-interest statements, and evidence evaluation through 12 appendices, providing methodological support for the clinical translation of the consensus. In the future, it will be continuously improved through a dynamic revision mechanism.

Objective To evaluate the effect of a multidisciplinary collaborative quality control management (hereinafter referred to as "QC management") on improving the performance of biological safety cabinets in hospital. Methods A total of 63 ClassⅡbiological safety cabinets in active use at Peking University Third Hospital were selected as the study subjects using the before-after study mode. Conventional management was implemented on the biological safety cabinets from 2018 to 2021. QC management was used in 2022. The compliance of biological safety cabinets management norm and performance differences under the two models were compared. Results The median and the 25th and 75th percentiles [M(P25, P75)] of the service life among these 63 biological safety cabinets were 3 (1,6) years. The overall performance pass rate and inflow velocity pass rate of biological safety cabinets were higher in the QC management than that in the conventional management (90.5% vs 65.1%, 96.8% vs 84.1%, both P<0.05). However, there was no significant difference in downflow velocity, high-efficiency particulate air filter integrity, cleanliness, airflow smoke pattern, noise, and illumination pass rates of biosafety cabinets before and after the implementation of QC management (79.4% vs 88.9%, 90.5% vs 100.0%, 96.8% vs 100.0%, 85.7% vs 100.0%, 100.0% vs 100.0%, and 85.7% vs 96.8%, respectively; all P>0.05). Conclusion sQC management improves the standardization of biological safety cabinet management and key performance indicators in hospital.

This paper reports a case of red ear syndrome, a rare clinical condition, treated with acupuncture. At the initial consultation, the diagnosis was unclear from a western medical perspective. The advantage of traditional Chinese medicine in "prioritizing symptoms and syndrome differentiation" was fully utilized. Based on the patient's clinical manifestations, disease progression, tongue and pulse conditions, the treatment addressed the branch by targeting meridian qi stagnation based on the hand-taiyang sinew meridian theory, and treated the root by selecting acupoints according to syndrome differentiation for liver and kidney yin deficiency. A combined treatment of tendon needling and acupuncture produced immediate results after the first session. Subsequent sessions were administered every other day for a total of ten treatments. The patient's ear pain and redness symptoms had nearly disappeared, and a two-month follow-up showed good overall condition.
