Ulcerative colitis （UC）， a chronic relapsing inflammatory bowel disease， involves multifaceted pathological mechanisms such as intestinal barrier dysfunction， immune dysregulation， and oxidative stress. Current therapeutic strategies remain limited in efficacy and safety. In recent years， the adenosine monophosphate-activated protein kinase （AMPK） signaling pathway has emerged as a pivotal therapeutic target for UC due to its central role in energy metabolism， inflammatory regulation， and intestinal homeostasis. This article systematically reviewed the mechanisms by which traditional Chinese medicine （TCM） prevented and treated UC through the regulation of the AMPK signaling pathway， with a focus on elucidating AMPK's multidimensional regulatory network in inflammatory signaling crosstalk， alleviating oxidative stress， restoring intestinal immune balance， repairing the intestinal barrier， and modulating gut microbiota. Leveraging its unique advantages of multi-target engagement and low toxicity， TCM demonstrates promising potential in UC treatment and has become a focal area of research. By systematically summarizing and synthesizing the existing literature on TCM-mediated AMPK pathway modulation in UC， this review aims to provide a theoretical foundation for advancing mechanistic research and clinical interventions in UC.

Objective:To analyze the screening results of the Urban Cancer Early Diagnosis and Treatment Project in Qinghai Province from 2019 to 2024.Methods:A summary and statistical analysis were conducted on six years of screening data from the Urban Cancer Early Dia-gnosis and Treatment Program in Qinghai Province,with the high-risk rate,screening rate,and detection rate calculated separately for each type of cancer.Results:From 2019 to 2024,56,882 high-risk individuals were identified.The high-risk rates for lung,colorectal,breast,up-per gastrointestinal,and liver cancer were 22.02%,21.57%,14.23%,13.52%,and 6.10%,respectively.Overall,13,592 individuals com-pleted clinical screening,with detection rates of 0.32%for lung cancer,0.41%for liver cancer,0.08%for precancerous gastric lesions,3.63%for precancerous colorectal lesions,0.08%for esophageal cancer,0.16%for gastric cancer,and 0.14%for colorectal cancer.Conclusions:The implementation of the Urban Cancer Early Diagnosis and Treatment Program in Qinghai Province aids in the early detection of cancer,improves early diagnosis and survival rates,and reduces mortality.Nevertheless,due to low public awareness and limited participation,en-hancements in program management and public outreach are required.

Ulcerative colitis （UC）， a chronic， non-specific inflammatory bowel disease with typical symptoms such as abdominal pain， diarrhea， and bloody stools， demonstrates a high relapse rate and difficulty in curing. Sishenwan， first recorded in Internal Medicine Abstract （Nei Ke Zhai Yao）， are a classic prescription for treating diarrhea caused by deficiency of the spleen and kidney Yang. The core therapeutic principle of Sishenwan is warming and tonifying the spleen and kidney， and astringing the intestine and stopping diarrhea. In recent years， Sishenwan have demonstrated distinct advantages in the clinical treatment of UC. The pathogenesis of UC involves multiple factors， including immune dysregulation and gut microbiota imbalance. Although Western medicine is effective in the short term， its side effects， high relapse rate， and resistance associated with long-term use pose substantial challenges. Sishenwan have shown excellent clinical outcomes in the treatment of UC due to deficiency of the spleen and kidney Yang. Modern clinical studies indicate that Sishenwan， used alone or in combination with Western medicine or other Chinese medicine compound prescriptions， significantly improve the clinical efficacy in treating UC due to deficiency of the spleen and kidney Yang. Sishenwan effectively alleviate core symptoms such as mucus， pus， and blood in stools， and persistent abdominal pain， reduce Mayo scores and the relapse rate， and improve patients' quality of life. Research on the material basis reveals that Sishenwan contain multiple active ingredients such as psoralen， isopsoralen， and evodiamine. Mechanism studies indicate that Sishenwan inhibit the inflammatory cascade reactions by regulating the signal network through multiple targets. Sishenwan regulate cellular immunity and restore intestinal immune homeostasis. At the microecological level， Sishenwan promote the intestinal barrier repair through the "microbiota-metabolism-immunity" axis. The current research still needs to be deepened in aspects such as the mining of specific biomarkers for syndromes and the exploration of the collaborative mechanism of traditional Chinese and Western medicine. In the future， a full-chain system covering syndrome differentiation， targeting， and monitoring needs to be constructed for promoting the paradigm transformation of Sishenwan into precision drugs. This review systematically explains the treatment mechanism of Sishenwan regarding the combination of disease and syndrome and its multi-target regulatory characteristics， providing a theoretical basis and transformation direction for the treatment of UC with integrated traditional Chinese and Western medicine.

Objective To explore the mechanism of Kangliu Zengxiao Jiandu Prescription(KLJD)in enhancing the efficacy of cisplatin chemotherapy in non-small cell lung cancer(NSCLC)through network pharmacology and in vivo/in vitro experiments.Methods Components of KLJD were screened via the TCMSP database to identify active components and potential targets.Lung cancer-related genes were obtained from the GeneCards and OMIM databases.GO and KEGG pathway enrichment analysis was performed on drug-disease intersection targets using the Metascape database;molecular docking was performed between core target proteins and main active components.A Lewis lung cancer mouse model was established,and intervened with KLJD and cisplatin.Organ indexes and tumor inhibition rate were counted,and Western blot and RT-PCR were used to detect the expressions of key pathway target proteins and mRNA;A549 and H1299 cells were intervened with KLJD,and Western blot was used to detect key target protein expressions.Results Network pharmacology identified 74 active components and 20 key targets of KLJD,primarily involved in biological processes such as cell proliferation and inflammatory response,and pathways in cancer and PI3K/AKT signaling pathway;molecular docking revealed stable binding between EGFR and major compounds.Animal experiments demonstrated that,compared with the model group,the KLJD group showed significantly higher tumor inhibition rate(P<0.01)and downregulation of EGFR,AKT and PI3K protein and mRNA expression in tumor tissues(P<0.05).Compared with the cisplatin group,the combination group exhibited significantly enhanced tumor inhibition rate(P<0.01),elevated thymic and splenic indices(P<0.01),and decreased EGFR,PI3K and AKT protein and mRNA expressions(P<0.01).Cell experiments showed that KLJD concentration-dependently inhibited A549 and H1299 cell proliferation(IC50:14.72 mg/mL and 14.68 mg/mL,respectively).Combined with cisplatin,KLJD synergistically down-regulated EGFR PI3K and AKT protein expressions(P<0.01).Conclusion KLJD effectively enhances cisplatin's chemotherapeutic efficacy in NSCLC by inhibiting the EGFR/PI3K/AKT pathway while improving immune organ function.Its mechanism likely involves multi-target regulation,including suppression of tumor proliferation,promotion of apoptosis,and modulation of the immune microenvironment.

Objective:To characterize the minimal inhibitory concentration (MIC) of macrolides against clinical Mycoplasma pneumoniae (MP) isolates and to investigate the significance of 23S rRNA mutations. Methods:Cross-sectional study.A total of 288 clinical MP strains preserved in the laboratory from 2016 to 2021 were taken for macrolide resistance gene testing and the evaluation of in vitro susceptibility to Azithromycin and Erythromycin.MIC 50 and MIC 90 values were calculated separately for macrolide-susceptible and -resistant strains. Results:All 288 MP strains underwent the test of in vitro susceptibility to Azithromycin, while 86 of them were additionally tested for Erythromycin.Among these strains, 22 strains were Azithromycin-sensitive, and 266 strains were Azithromycin-resistant.A2063G mutations were detected in 260 (97.7%) strains, while A2064G mutations were detected in 6 (2.3%) strains.Azithromycin-resistant strains had an MIC 50 of 128.000 μg/mL and an MIC 90 of 512.000 μg/mL, with the MIC ranging between 16.000 and 512.000 μg/mL.Seven strains were sensitive and 79 strains were resistant to Erythromycin.Among Erythromycin-resistant strains, A2063G mutations were detected in 73 (92.4%) strains, while A2064G mutations were detected in 6 (7.6%) strains.Erythromycin-resistant strains had an MIC 50 of 256.000 μg/mL and an MIC 90 of 512.000 μg/mL, with the MIC ranging between 64.000 and 1 024.000 μg/mL. Conclusions:A2063G and A2064G mutations in the 23S rRNA gene of MP are associated with high-level in vitro resistance to Azithromycin and Erythromycin, significantly limiting the clinical effectiveness of these antibiotics.Early resistance gene testing is recommended for suspected MP patients, which can help optimize the treatment, improve prognosis, and prevent resistance spread.

ObjectiveTo investigate the mechanism of neferine（Nef） in promoting vascular regeneration against cerebral ischemia through modulation of mitochondrial calcium uniporter（MCU） ion channel. MethodTaking the area of subintestinal vessels in microvascular deficiency zebrafish as an index， the vascular regenerative efficacy of Nef was evaluated， and the median effective concentration（EC₅₀） was calculated. Rats were randomly divided into a sham operation group， a model group， a positive drug group（butylphthalide， 6 mg·kg^-1）， and Nef low， medium， and high dose groups（0.125， 0.625， 3.125 μg·kg^-1）. Except for the sham operation group， the middle cerebral artery occlusion（MCAO） model was established in other groups. After modeling， the groups were administered the corresponding dose of drugs by gavage， while the sham operation and model groups received equal volumes of saline， once a day for 7 consecutive days. Neurobehavioral scores were assessed for each group of rats， and the infarct rate of ischemic brain tissue was calculated by 2，3，5-triphenyltetrazolium chloride（TTC） staining. The regional cerebral blood flow（rCBF） of each group was measured using a speckle contrast imaging. Immunofluorescence and Western blot were conducted to detect the expression of vascular endothelial growth factor（VEGF）， platelet endothelial cell adhesion molecule-1（CD31）， and hypoxia-inducible factor-1α（HIF-1α） proteins in each group. Human umbilical vein endothelial cells（HUVECs） were divided into the normal group， model group， positive drug group（astragaloside Ⅳ， 10 μmol·L^-1）， and Nef group （32 nmol·L^-1）. In the verification of mitochondrial protection of Nef and its mechanism in promoting vascular regeneration， the spermine（MCU agonist） and Nef+spermine group were added. HUVECs model of oxygen-glucose deprivation（OGD） was established in all groups except the normal group， the cell viability was assessed using 3-（4，5-dimethylthiazol-2-yl）-2，5-diphenyltetrazolium bromide（MTT） assay， and cell migration ability was evaluated through scratch and tube formation assays. Fluorescent probes（Rhod-2 AM， Fluo-3 AM， JC-1， Calcein AM） and a cellular energy metabolism analyzer were used to analyze the mitochondrial protective effects of Nef. Molecular docking was performed to predict the binding ability of Nef with MCU and HIF-1α， and Western blot was used to detect the effects of Nef on the protein expressions of MCU， B-cell lymphoma-2 associated X protein（Bax）， Caspase-3 and HIF-1α in the OGD model HUVECs. ResultThe results of vascular regeneration in microvascular deficiency zebrafish showed that compared to the normal group， the area of subintestinal vessels in the model group significantly decreased（P<0.01）. Compared to the model group， different concentrations of Nef could significantly increase the area of subintestinal vessels（P<0.01）， with the maximum tolerated concentration of 10.24 μmol·L^-1 and the EC₅₀ of 0.23 μmol·L^-1. Anti-cerebral ischemia results on MCAO rats showed that compared to the sham operation group， the model group had a significant decrease in rCBF and a significant increase in infarct rate， while CD31 expression significantly decreased（P<0.01）， and VEGF and HIF-1α protein expressions significantly increased（P<0.05）. Compared to the model group， the treated groups showed significant increases in rCBF， significant reductions in infarct volume， and significant increases in CD31， VEGF， and HIF-1α protein expression（P<0.01）. Cell experiment results showed that compared to the normal group， the model group had decreased cell viability and migration ability， increased intracellular Ca²⁺ and mitochondrial Ca²⁺ levels， reduced mitochondrial permeability transition pore（MPTP） opening， and decreased mitochondrial energy metabolism capability， with increased expressions of MCU， Bax， Caspase-3 and HIF-1α proteins（P<0.05， P<0.01）. Compared to the model group， the Nef group showed increased cell viability and migration ability， decreased intracellular Ca²⁺ and mitochondrial Ca²⁺ levels， increased MPTP opening， enhanced mitochondrial energy metabolism capability， decreased expressions of MCU， Bax and Caspase-3 proteins， and increased HIF-1α protein expression（P<0.05， P<0.01）. ConclusionNef can stabilize mitochondrial membrane potential and inhibit mitochondrial apoptosis. By down-regulating the expression of MCU， it suppresses the activation of intracellular Bax and Caspase-3 while activating the HIF-1α signaling pathway， enhancing the expression of VEGF and CD31， thereby promoting vascular regeneration to treat ischemic brain injury.
