Colorectal cancer （CRC） is one of the most common cancers， with its incidence ranking high among cancers. It stands as the second leading cause of cancer-related death worldwide. In the early stages， CRC lacks specific symptoms， and most patients are diagnosed at advanced stages， making it a major research focus in the field of gastrointestinal tumors. Currently， clinical CRC treatments face several common challenges， including high surgical risks， frequent metastasis and recurrence， drug resistance， and significant side effects from chemotherapy and radiation therapy. With the development and application of traditional Chinese medicine （TCM）， it has been found that TCM and its active ingredients can effectively inhibit CRC cell proliferation， invasion， migration， and angiogenesis， and promote apoptosis and autophagy， thereby slowing the progression of CRC. This has become a key focus of CRC treatment research. Salvia Miltiorrhiza has multiple pharmacological effects， including activating blood circulation to dispel blood stasis， unlocking meridians to relieve pain， clearing heat to calm irritability， and cooling blood to reduce abscesses. It contains a variety of chemical components， including diterpenoids， phenolic acids， flavonoids， polysaccharides， nitrogen-containing compounds， steroids， and lactone compounds. This review summarized the molecular mechanisms of Salvia miltiorrhiza and its active ingredients in the treatment of CRC. It is found that these ingredients exert anti-CRC effects through various molecular mechanisms， including cell cycle arrest， promotion of apoptosis， inhibition of cell invasion and migration， induction of autophagy， suppression of tumor angiogenesis， and remodeling of the tumor microenvironment. The review aims to provide new insights for the drug development and clinical application of Salvia miltiorrhiza in CRC treatment.

Objective: To investigate the correlation between color parameters (L^*, a^*, b^*, Eab^*) and the contents of reducing sugars, total polysaccharides, total oligosaccharides, as well as four saccharides (fructose, glucose, sucrose, and kestose) during the nine cycles of steaming and sun-drying processing of Polygonatum kingianum, and to preliminarily explore the optimal processing duration.
Methods: The color changes were objectively evaluated using a colorimeter. The anthrone-sulfuric acid method was employed to determine total polysaccharides and oligosaccharides. The 3,5-dinitrosalicylic acid (DNS) colorimetric method was used to measure total reducing sugar content. High-performance liquid chromatography coupled with charged aerosol detection (HPLC-CAD) was applied for quantitative analysis of fructose, glucose, sucrose, and kestose. Multivariate statistical analysis was conducted to assess samples from different processing stages.
Results: Significant variations in color and component contents were observed across processing stages. The herbal pieces progressively darkened with increased processing cycles: brightness (L^*) and total color difference (Eab^*) initially decreased then stabilized, while a^* (red-green) and b^* (yellow-blue) values first increased then declined. Total polysaccharides and oligosaccharides showed overall decreasing trends, whereas reducing sugars initially increased before stabilizing. Fructose and glucose levels rose continuously, while sucrose and kestose decreased progressively, becoming undetectable after five cycles.
Conclusion: The chromatic alteration and saccharide composition of P. kingianum showed significant correlation with processing duration. Both total color difference (Eab^*) and reducing sugar content stabilized after four processing cycles (12 hours), suggesting that four cycles of steaming and sun-drying may represent the optimal processing duration.

Objective To investigate the risk factors for postoperative recurrence and metastasis in patients with T1 stageⅢ/Ⅳ clear cell renal cell carcinoma(ccRCC), and to analyze the influence of surgical methods on prognosis, so as to provide prognostic evaluation and treatment guidance for clinical practice. Methods A retrospective analysis was conducted on 398 patients diagnosed with T1 stage Ⅲ/Ⅳ ccRCC who underwent either partial nephrectomy(PN)or radical nephrectomy(RN)at Jiangsu Province Hospital during Jan. 2008 and Sep. 2022. The patients were divided into recurrence group(n=49)and non-recurrence group(n=349)according to whether the tumor recurred during the follow-up period. The general, clinical data and prognosis were compared between the two groups. Univariate and multivariate Cox regression analyses were used to explore the factors influencing disease-free survival(DFS)and overall survival(OS)after surgery. Subgroup analysis using Kaplan-Meier curves was performed for T1a and T1b patients. Results During the median follow-up of 67(42, 98)months, the recurrence group was characterized by older age, larger tumor diameter, higher proportion of T1b stage, and more complex tumor anatomy. Univariate and multivariate Cox regression analyses showed that age ≥55 years and R.E.N.A.L. score ≥7 were independent risk factors for poorer DFS and OS(P＜0.05). Subgroup analysis revealed that PN or RN did not significantly affect DFS or OS in T1a patients and OS in T1b patients, while RN significantly improved DFS in T1b patients(P＜0.05). Conclusion Age ≥55 years and R.E.N.A.L. score ≥7 are independent risk factors for poor DFS and OS in highgrade T1 ccRCC patients. For T1b patients, RN may improve DFS.

OBJECTIVE To compare the efficacy and safety of dupilumab versus thalidomide in the treatment of refractory prurigo nodularis （PN） in adults. METHODS A retrospective analysis was conducted on the clinical data of 123 adult patients with refractory PN admitted to Wuhan First Hospital from May 2021 to June 2024. Among them， 63 patients who received dupilumab comprised the observation group and 60 patients who received thalidomide comprised the control group. Clinical efficacy indicators [Investigator Global Assessment （IGA） score， Pruritus Numerical Rating Scale （P-NRS） score， Patient-Oriented Eczema Measure （POEM） score， and Dermatology Life Quality Index （DLQI） score]， allergic biomarkers [eosinophil （EOS） count in peripheral blood and serum total immunoglobulin E （IgE） level]， psychological scores [Hospital Anxiety and Depression Scale （HADS）] before and after treatment， as well as the occurrence of adverse drug reaction during treatment， were compared between the two groups. RESULTS Before treatment， there were no statistically significant differences between the two groups in above clinical efficacy indicators， allergic biomarkers， or psychological scores （P＞0.05）. At 4， 8， 12 and 16 weeks after treatment， both groups showed significant decreases in IGA score （except for the control group 4 weeks after treatment）， IGA activity score （except for the control group 4 weeks after treatment）， P-NRS score， POEM score， DLQI score （except for the control group 4 weeks after treatment）， serum EOS count， and serum total IgE level compared with baseline （P＜0.05）； at 12 and 16 weeks after treatment， scores on both the HADS-anxiety subscale and HADS-depression subscale were also significantly lower than baseline in both groups （P＜0.05）； the observation group was significantly lower than the control group （P＜0.05）. The overall incidence of adverse events was 12.70% in the observation group， which was significantly lower than 28.33% in the control group （P＜0.05）. CONCLUSIONS Dupilumab treatment in adults with refractory PN demonstrates superior efficacy compared with thalidomide in improving skin lesions， relieving pruritus， reducing peripheral EOS counts and serum total IgE， and improving quality of life and psychological status， while showing a more favorable safety profile.

Objective:To investigate the expression of N6-methyladenosine(m6A)reader heterogeneous nuclear ribonucleoprotein A2/B1(hnRNPA2B1)in human gastric cancer(GC)tissue and its effect on the proliferation and invasion of MKN-28 cells.Methods:The Cancer Genome Atlas and Gene Expression Omnibus were used to analyze the expression of hnRNPA2B1 and long noncoding RNA(ln-cRNA)mir-100-let-7a-2-mir-125b-1 cluster host gene(MIR100HG)in GC tissue and their association with the clinical prognosis of patients with GC.Quantitative PCR and Western blotting were used to measure the effect of hnRNPA2B1 on the expression level of MIR100HG and its downstream Wnt/β-catenin signaling pathway;Methylated RNA immunoprecipitation(MeRIP)was used to mea-sure the m6A level of MIR100HG;CCK-8 assay and Transwell assay were used to observe cell proliferation and invasion.Results:Com-pared with paracancerous tissue,human GC tissue showed significant increases in the expression levels of hnRNPA2B1(t=6.101,P<0.001)and MIR100HG(t=2.191,P=0.036 7),and the high expression levels of hnRNPA2B1 and MIR100HG were associated with poor survival in patients with GC.Knockdown of hnRNPA2B1 reduced the mRNA expression level(t=5.156,P=0.007)and m6A level of MIR100HG(t=4.789,P=0.010),inhibited the proliferation and invasion of MKN-28 cells(t=4.915,P=0.008 and t=5.167,P=0.007),and blocked the activity of the Wnt/β-catenin signaling pathway(P<0.05).Overexpression of MIR100HG promoted cell pro-liferation and invasion(t=3.578,P=0.023 and t=8.411,P=0.001),activated the Wnt/β-catenin signaling pathway(P<0.01),and re-versed the antitumor effect induced by hnRNPA2B1 knockdown(t=3.667,P=0.021).Conclusion:This study shows that hnRNPA2B1-mediated m6A modification of MIR100HG promotes the proliferation and invasion of GC MKN-28 cells by activating the Wnt/β-catenin signaling pathway.

Thyroid cancer is caused by multiple factors, including genetics, environment, metabolism, and the immune microenvironment, among which ionizing radiation exposure is an important risk factor for thyroid cancer. As one of the most sensitive target organs of ionizing radiation, the thyroid gland may have different risks of thyroid cancer caused by different types of ionizing radiation exposures, such as medical exposure, occupational exposure, and emergency exposure. The sensitivity of children and adolescents are higher than that of adults. The dose-response relationship still needs to be further explored. The molecular mechanism between ionizing radiation and the increased risk of thyroid cancer is complex, which may involve DNA damage and repair abnormalities, gene mutations, non-coding RNA regulation, DNA methylation, cell cycle regulation imbalance, and immune microenvironment changes. This article reviews the risk and molecular mechanisms associated with different types of ionizing radiation exposure in thyroid cancer, based on literature retrieved from CNKI and PubMed databases. It aims to provide a theoretical basis for the early monitoring, prevention, and intervention of thyroid cancer related to ionizing radiation exposure.

Methods:This study was a cross-sectional study. A prospective cohort study enrolled 42 patients with clinically suspected acute cerebrovascular disease and those undergoing follow-up examinations after intracranial vascular stenting at the First Affiliated Hospital of Zhengzhou University from June 2024 to May 2025. All patients underwent UHR PCD-CT examinations of the head and neck. Reconstructions were performed based on raw data, yielding conventional standard resolution (SR group) reconstructions and UHR images reconstructed using four distinct convolution kernels (Hv40, Hv48, Hv56, Hv64) in separate groups (Hv40 UHR group, Hv48 UHR group, Hv56 UHR group, Hv64 UHR group). Regions of interest were selected in the anterior cerebral artery, middle cerebral artery, posterior cerebral artery, posterior communicating artery, and anterior communicating artery. CT values and standard deviation (SD) values were measured for each artery, and signal-to-noise ratio (SNR) and contrast-to-noise ratio (CNR) were calculated. Additionally, the sharpness of the vessel edges and the full-width-half-maximum (FWHM) of each artery were measured. One-way analysis of variance or the nonparametric Kruskal-Wallis test was used to compare the subjective and objective image quality metrics across the five groups. Pairwise comparisons were performed using the LSD test or Dunn method.Results:Statistically significant differences were observed in the overall comparison of vascular imaging SD, SNR, CNR, vascular edge sharpness, and FWHM among the SR group, Hv40 UHR group, Hv48 UHR group, Hv56 UHR group, and Hv64 UHR group ( P<0.05). No statistically significant differences in CT values were found ( P>0.05). Pairwise comparisons revealed statistically significant differences between all groups ( P<0.05), except that no significant differences were observed in image SD, SNR, CNR, vascular edge sharpness, or FWHM between the Hv56 UHR and Hv64 UHR groups ( P>0.05). Conclusions:UHR PCD-CT provides better image quality for neurovascular imaging. For the display of small intracranial vessels, the Hv64 provides sharper vessel walls and better subjective image quality compared to the less sharp convolutional cores.Objective:To explore the value of ultra-high resolution (UHR) photon-counting detector CT (PCD-CT) to improve the quality of neurovascular images.

Objective To observe the clinical and CT findings of hepatic perivascular epithelioid cell tumor(PEComa)compared with liver cancer and liver adenoma.Methods Thirty patients with hepatic PEComa,31 patients with liver cancer and 31 patients with liver adenoma were retrospectively enrolled.Compared with liver cancer and liver adenoma,the clinical and CT findings of hepatic PEComa were observed.Results Significant differences of patients' gender,age and symptoms,also of the proportion of hepatitis,cirrhosis and positive alpha fetoprotein(AFP)were found between hepatic PEComa group and liver cancer group(all P＜0.05),while of patients' gender and age were found between hepatic PEComa group and liver adenoma group(both P＜0.05).Significant differences of the proportion of fat and malformed blood vessels,enhancement mode,as well as contrast enhancement ratio CER of arterial and venous phases were noticed between hepatic PEComa group and liver cancer group(all P＜0.05),while of the proportion of fat,capsule and malformed blood vessels,as well as enhancement mode and CER of arterial and venous phases were noticed between hepatic PEComa group and liver adenoma group(all P＜0.05).Conclusion Compared with liver cancer and liver adenoma,hepatic PEComa was mostly benign and more common in women,with somewhat characteristic CT findings being helpful to differential diagnosis.

With the intensification of population aging, type 2 diabetes has emerged as a significant global public health concern, particularly in developing countries.Epidemiological data indicate that the elderly population faces a higher risk of diabetes, accompanied by an increasing incidence rate.Due to the unique pathological characteristics and comorbid chronic diseases prevalent among elderly diabetes patients, polypharmacy is both common and often unavoidable.Inappropriate polypharmacy poses heightened health risks for patients and complicates clinical management, underscoring the urgent need to optimize intervention strategies.Effective approaches include regular medication reviews, adjustments to blood glucose control targets, and the development of personalized deprescribing plans informed by comprehensive geriatric assessments.While some interventions have demonstrated positive effects in reducing potentially inappropriate medications, addressing prescription omissions, and enhancing medication adherence, their capacity to yield significant clinical improvements requires further validation.Future research should prioritize the identification of the most effective interventions for high-risk populations.
