Cholangiocarcinoma (CCA) is a malignancy characterized by tumor cells originating in the liver or bile ducts, exhibiting features of cholangiocyte differentiation. It poses a significant clinical challenge due to the limited diagnostic and therapeutic options available. Robust animal models are essential for advancing our understanding of CCA pathogenesis and developing effective treatments. This review provides a comprehensive overview of CCA mouse models, highlighting various approaches, including chemical induction, genetically engineered models, and tumor xenografts. Each model is discussed in terms of its establishment techniques, pathological characteristics, and research significance, with a focus on intrahepatic CCA. Chemical induction models, such as diethylnitrosamine- and azoxymethane-induced models, offer insights into tumorigenesis processes, whereas genetically modified models involving alterations in key genes such as Kirsten rat sarcoma viral oncogene homolog, tumor protein 53, and isocitrate dehydrogenase serve as important tools for studying the molecular mechanisms underlying CCA. Xenograft models, including patient-derived xenografts, bridge the gap between experimental research and clinical applications, allowing for precise therapeutic evaluations. By comparing these models, this review underscores their respective advantages and limitations, paving the way for future studies aiming to optimize and innovate CCA modeling strategies.

Background: The surgical neck of the humerus is located approximately 2–3 cm distal to the anatomical neck (collum anatomicum) at the junction of the greater and lesser tubercles and the humeral shaft. Owing to the transition between cortical and cancellous bones, this region is biomechanically vulnerable and prone to fractures, particularly in older adults. Fractures of the surgical neck of the humerus are classified under the International Classification of Diseases, 10th Revision (ICD-10), with diagnostic codes S42.21.3, S42.22, and S42.23. National statistics indicate that 210,763 new trauma cases were reported in Mongolia in 2023, representing an 11.6% increase compared to the previous year, of which 11,452 cases (5.4%) involved shoulder and humeral injuries. Aim: This study aimed to compare the clinical effects of traditional Mongolian bone-setting therapy and surgical treatment on pain intensity, shoulder function, range of motion, and activities of daily living in patients with surgical neck of the humerus fractures. Materials and Methods: Based on the Department of Traditional Therapies of the Mongolian National University of Medical Sciences (MNUMS) and the Department of Orthopedic Trauma of the Inner Mongolia International Hospital, Inner Mongolia Autonomous Region, China, a total of 60 patients diagnosed with surgical neck fractures of the humerus were enrolled in this study between January 2024 and December 2025. The patients were randomly assigned into two groups: a Mongolian traditional bone-setting therapy group (n=30) and a surgical treatment group (n=30). Assessments were conducted before treatment and at 1 month and 3 months after treatment. Shoulder joint range of motion, activities of daily living, and muscle strength were evaluated using the Constant–Murley score, while pain intensity was assessed using the Visual Analog Scale (VAS). The collected data were systematically analyzed, and the therapeutic outcomes of the two treatment modalities were comprehensively compared and summarized. Result: The baseline demographic and clinical characteristics were comparable between the groups. In the traditional bone-setting group, VAS scores decreased significantly, whereas Constant–Murley scores improved markedly at both follow-up points. The overall outcomes in the traditional bone-setting group were significantly better than those in the surgical group (P<0.05). Conclusion Traditional Mongolian bone-setting therapy offers rapid pain relief, superior long-term functional recovery, and fewer complications, making it a valuable treatment option, particularly for elderly patients and those unsuitable for surgery.

Background: Mongolian traditional bone-setting is a non-surgical treatment method for fractures; however, there is a lack of evidencebased research evaluating its effectiveness, which forms the basis of our study. Aim: To study the therapeutic efficacy of traditional bonesetting treatment for surgical neck fractures of the humerus. Materials and Methods: From June 2023 to June 2025, 120 patients diagnosed with surgical neck fractures of the humerus and treated at the Inner Mongolia International Mongolian Hospital were randomly divided into a traditional bone-setting group (n=64) and a surgical treatment group (n=56). Shoulder and upper limb function were evaluated at 1, 3, and 6 months after treatment using the Constant–Murley score, Oxford Shoulder Score (OSS), and Visual Analog Scale (VAS) for pain. Result: A total of 120 patients with surgical neck fractures of the humerus were divided into two groups, with no significant differences in the baseline characteristics (p>0.05).In the traditional bone-setting group, pain (VAS) decreased more rapidly at 1–3 months (p<0.01), while activities of daily living and functional outcomes improved significantly at 3–6 months (p<0.01). At 6 months, shoulder function (Constant–Murley score) was significantly improved (p=0.049).In contrast, the surgical group showed faster recovery in joint range of motion and muscle strength in the early stage; however, by 6 months, the outcomes between the two groups were comparable. Conclusion In the treatment of surgical neck fractures of the humerus, no significant difference was observed between traditional bone-setting and surgical treatment in terms of shoulder range of motion and muscle strength recovery. However, the advantages of traditional bone-setting lie in its ability to relieve pain more rapidly, promote faster functional recovery, improve activities of daily living, and achieve better long-term outcomes than modern bone-setting. Therefore, traditional bone setting is a safe and effective treatment method that aligns with modern theories of bone healing and rehabilitation principles and holds significant value for wider clinical application and further research in the management of surgical neck fractures of the humerus.

Objective:To compare the effects of intermittent oro-esophageal tube feeding (IOE) and nasogastric tube feeding (NGT) on nutritional status, complications, swallowing function and airway protection in persons with post-stroke dysphagia (PSD).Methods:Sixty PSD patients were randomized into an observation group ( n=30) and a control group ( n=30). In addition to conventional medication and swallowing rehabilitation, the observation group received supplemental IOE nutrition, while the control group was given NGT. Before and after one month, both groups were evaluated using the Functional Oral Intake Scale (FOIS), and such nutritional indicators as body mass index (BMI), hemoglobin (Hb) levels, albumin (ALB), prealbumin (PAB), skinfold at the triceps (TSF) and arm muscle circumference (AMC) were measured. The morphology of each subject′s epiglottis, any edema of the arytenoid mucosa and vocal cord mobility were assessed using fiberoptic endoscopic evaluation of swallowing (FEES). Murray Secretion Scale ratings were documented, along with laryngeal sensation during swallowing, swallowing reflex, the Yale Pharyngeal Residue Severity Rating Scale, and the Rosenbek Penetration-aspiration Scale. Results:Both groups showed significant improvement in their average FOIS scores and all of the nutritional descriptors, but with significantly greater improvement in the observation group. Abnormalities in the shape of the epiglottis, arytenoid edema and vocal cord mobility had decreased significantly in both groups. This was also true of larynx sensation, swallowing reflex, pharyngeal secretions, residue and penetration/aspiration. On average the improvements were significantly greater in the observation group.Conclusion:Compared with NGT, IOE more effectively improves swallowing, enhances airway functioning and reduces NGT syndrome among PSD patients. These observations support its clinical adoption.

Objective To investigate the role of the GPR120 gene in the progression of sepsis,explore the molecular mechanisms through which GPR120 gene regulates NOD-,LRR-and pyrin domain-containing protein 3(NLRP3)inflammasome activation and macrophage polarization.Methods The blood and pleural fluid samples were collected from the sepsis patients and the control group.The expression of inflammatory factors and the associated proteins were detected by flow cytometry and ELISA.C57BL/6 mice and monocyte-macrophage cell line(Raw264.7)were treated with lipopolysaccharide(LPS)to construct the sepsis models.After the intervention of GPR120 agonist TUG891,the expression of GPR120 gene,NLRP3 inflammasome protein and macrophage polarization protein were detected between the control group and the sepsis group.Results The expression of inflammatory factors,such as IL-1β in the serum of septic patients,significantly increased compared with the control(P<0.001).And the expression of inflammasome proteins such as NLRP3,Caspase-1 and IL-1β in the pleural fluid also increased(all P<0.05).In vivo,LPS could induce severe inflammation in lung tissue,the GPR120 gene expression decreased in lung tissue,and inflammatory factors were up-regulated in mouse serum(P<0.01).The inflammasome-associated protein and M1 type polarization of macrophages were enhanced,the TUG891 could reduce the inflammatory response,inhibit the NLRP3 inflammasome activating,and promote the M2 polarization of macrophages(P<0.01).In vitro,LPS could inhibit the intracellular GPR120 expression.The inflammatory factors secreted more in LPS-induced sepsis cells.TUG891 could promote the up-regulation of GPR120 protein and alleviate the secretion of inflammatory factors(P<0.05).Conclusion In sepsis,GPR120 gene activation could inhibit the NLRP3 inflammasome activation,promote macrophage polarization,and reduce the inflammatory damage,thereby delay the rapid progression of sepsis.

To effectively carry out community health education and prevention and control of chronic obstructive pulmonary disease(COPD),we conducted a questionnaire survey on the awareness of COPD knowledge among residents aged 40 and above in Jiading District of Shanghai by using two-stage sampling method.We included 1 783 permanent residents in 4 districts and collected 1 666 valid questionnaires.The awareness rates of COPD name,pulmonary function test and related knowledge were 15.9%,11.9%and 17.2%,respectively.For the main symptoms of COPD,the awareness rate of sputum was the lowest(65.2%),of shortness of breath and dyspnea was the highest(78.4%).For the risk factors,the awareness rate of severe respiratory tract infection in childhood was the lowest(67.3%),of smoking was the highest(86.8%).Multiple response analysis showed that mobile phones and computers accounted for the highest proportion of acquiring knowledge of COPD(66.7%).Multivariate logistic regression analysis showed that low educational level,low monthly income,engaged in production and manufacturing,never or less exercise,no use of indoor air improvement measures,no wearing of masks in public places and no vaccination of influenza vaccine per year were associated with lower awareness rate of COPD.The community should improve the way and ability of health science popularization,and carry out health education for key groups.

Neuropathic pain, a debilitating condition caused by dysfunction of the somatosensory nervous system, remains difficult to treat due to limited understanding of its molecular mechanisms. Bioinformatics analysis identified cerebellin 2 (CBLN2) as highly enriched in human and murine proprioceptive and nociceptive neurons. We found that CBLN2 expression is persistently upregulated in dorsal root ganglia (DRG) following spinal nerve ligation (SNL) in mice. In addition, transcription factor SOX11 binds to 12 cis-regulatory elements within the Cbln2 promoter to enhance its transcription. SNL also induced SOX11 upregulation, with SOX11 and CBLN2 co-localized in nociceptive neurons. The siRNA-mediated knockdown of Sox11 or Cbln2 attenuated SNL-induced mechanical allodynia and thermal hyperalgesia. High-throughput sequencing of DRG following intrathecal injection of CBLN2 revealed widespread gene expression changes, including upregulation of numerous NF-κB downstream targets. Consistently, CBLN2 activated NF-κB signaling, and inhibition with pyrrolidine dithiocarbamate reduced CBLN2-induced pain hypersensitivity, proinflammatory cytokines and chemokines production, and neuronal hyperexcitability. Together, these findings identified the SOX11/CBLN2/NF-κB axis as a critical mediator of neuropathic pain and a promising target for therapeutic intervention.

OBJECTIVE: Varied acupoint selections represent a potential cause of the uncertainty surrounding the efficacy of acupuncture for knee osteoarthritis (OA). Skin temperature, a guiding factor for acupoint selection, may help to address this issue. This study explored thermal sensitization of acupoints used for the treatment of knee OA. METHODS: This cross-sectional case-control study enrolled cases aged 45-75 years with symptomatic knee OA and age- and gender-matched non-knee OA controls in a 1:1 ratio. All participants underwent infrared thermographic imaging. The primary outcome was the relative skin temperature of acupoint (STA), and the secondary outcome was the absolute STA of 11 acupoints. The Z test was used to compare the relative and absolute STAs between the groups. Principal component analysis was used to extract the common factors (CFs, acupoint cluster) in the STAs. A general linear model was used to identify factors affecting the STA in the knee OA cases. For the group comparisons of relative STA, P < 0.0045 (adjusted for 11 acupoints through Bonferroni correction) was considered to indicate statistical significance. For other analyses, P < 0.05 was used as the threshold for statistical significance. RESULTS: The analysis included 308 participants, consisting of 151 cases (mean age: [64.58 ± 6.67] years; male: 25.83%; mean body mass index: [25.70 ± 3.16] kg/m²) and 157 controls (mean age: [63.37 ± 5.96] years; male: 26.11%; mean body mass index: [24.47 ± 2.84] kg/m²). The relative STAs of ST34 (P = 0.0001), EX-LE2 (P < 0.0001), EX-LE5 (P = 0.0006), SP10 (P < 0.0001), BL40 (P = 0.0012) and GB39 (P = 0.0037) were higher in the knee OA group. No difference was found in the STAs of ST35, ST36, SP9, GB33 and GB34. Four CFs were identified for relative STA in both groups. The acupoints within each CF were consistent between the groups. The mean values of the relative STAs across each CF were higher in the knee OA group. In the knee OA cases, no factors were observed to affect the relative STA, while age and gender were found to affect the absolute STA. CONCLUSION Among patients with knee OA, thermal sensitization occurs in the acupoints of the lower extremity, exhibiting localized and regional thermal consistencies. The thermally sensitized acupoints that we identified in this study, ST34, SP10, EX-LE2, EX-LE5, GB39 and BL40, may be good choices for the acupuncture treatment of knee OA.
