"Sinew prescription correspondence" is the principle of selecting prescriptions for channel sinew diseases. On the basis of the theory of syndrome differentiation and treatment， the pulse manifestation corresponds to the channel sinew syndrome， which can improve the flexibility and standardization of clinical prescriptions. From the perspective of systematic dialectical sphygmology， this paper explains the dialectical relationship between channel sinew theory and pulse body elements， pulse wall elements， pulse elements and blood flow elements， and clarifies the internal relationship between pulse manifestation and prescriptions at the level of channel sinew disease. The prescription is derived from the method， while the method is established with the syndrome， and the prescription is unified by the method. According to the theory of "sinew prescription correspondence"， the treatment ideas of channel sinew diseases were analyzed from the perspective of channel sinew distribution， functional characteristics and structural changes. On this basis， the diagnosis of channel sinew disease and the application of prescriptions are expanded， and the research on the internal treatment and diagnosis mode of "pulse manifestation-channel sinew-zang fu （脏腑）" is prospected， so as to expand the differentiation and treatment methods of channel sinew theory.

Co-infection of hepatitis D virus （HDV） and hepatitis B virus （HBV） is the most severe form of viral hepatitis and is associated with accelerated progression of liver disease and a significant increase in the risk of liver cirrhosis and hepatocellular carcinoma. Nucleo（s）tide analogues for HBV treatment are ineffective against HDV infection， necessitating the urgent need for developing specific and effective antiviral therapies for HDV. In recent years， significant advances have been made in the research and development of specific antiviral drugs against HDV， including entry inhibitors targeting viral entry （Bulevirtide） and monoclonal antibody drugs （Libevitug）， which bring ground-breaking advances in the treatment of HDV infection. This article briefly reviews the latest research advances in therapeutic drugs for HDV， introduces the mechanism of action and clinical research data of new drugs recently approved for the treatment of HDV， and discusses the challenges that need to be solved in the field of HDV treatment， in order to provide a reference for understanding the current status of hepatitis D treatment.

Gorham-Stout disease(GSD) is a rare osteolytic disorder characterized by spontaneous and progressive osteolysis, along with abnormal angiogenesis and lymphangiogenesis, with no new bone formation. We present a case of a 15-year-old female admitted due to " recurrent right leg pain for 5 years, 11 months after undergoing right femoral fracture surgery". Through comprehensive integration of the patient's clinical phenotype, laboratory tests, imaging findings, pathological examinations, and molecular biological test results, GSD was considered highly likely. A multidisciplinary treatment approach was conducted, including a combination of zoledronic acid and sirolimus to inhibit osteolysis, along with rehabilitation training and orthopedic intervention, providing a personalized and comprehensive treatment strategy.

Myelodysplastic syndrome (MDS) is a chronic hematologic disorder characterized by ineffective hematopoiesis, dysplasia of one or more cell lines with or without definite genetic changes. Its diagnosis requires a comprehensive analysis combining morphology, immunology, cytogenetics, and molecular biology findings. In recent years, the development of second-generation sequencing (NGS) has provided great assistance in exploring the molecular pathogenesis of hematological malignancies and guidance for clinical practice. Mutations of a series of gene involved in RNA splicing, DNA methylation, transcriptional regulation, signal transduction, chromatin modification and cohesin complex have been identified as important mechanisms for the development of MDS, among which some mutations have been found to play important roles in the diagnosis, treatment, and prognosis of MDS. This article has provided a comprehensive review the the common molecular genetic abnormalities involved in MDS.

Objective To evaluate the effect of low-dose ¹⁸F-fluorodeoxyglucose (FDG) injection on image quality in pediatric patients, calculate the whole-body effective dose and absorbed doses to critical organs, and provide a reference for clinical protection in pediatric low-dose positron emission tomography/computed tomography (PET/CT) examination. Methods A total of 67 pediatric patients aged 4-14 years who underwent ¹⁸F-FDG whole-body PET/CT imaging in the Department of Nuclear Medicine, The First Affiliated Hospital of Shandong First Medical University between January 2024 and December 2025 were enrolled in a retrospective study. According to the injected ¹⁸F-FDG dose, patients were divided into a full-dose group (37 cases, 2.96-3.7 MBq/kg, PET acquisition duration of 10 min) and a low-dose group (30 cases, 1.85-2.4 MBq/kg, PET acquisition duration of 15 min). All scans were performed using a uEXPLORER PET/CT scanner. The standardized uptake value, standard deviation, and signal-to-noise ratio were measured for the liver and mediastinal blood pool. Image quality was compared between the two groups. The PET effective dose was calculated based on body mass index, and the total effective dose was obtained by combining PET effective dose with CT effective dose. The doses to critical organs were calculated according to ICRP Publication 128. Statistical analysis was performed using SPSS 26.0 and Prism 9.0 software. Differences were compared between groups. Results There were no significant differences in age, sex, weight, height, or body mass index between the two groups (P>0.05), while the injected dose showed a significant difference (P<0.001). In terms of image quality, there were no significant differences in standardized uptake value, standard deviation, and signal-to-noise ratio between the two groups. In terms of radiation dose, compared with the full-dose group, the low-dose group showed a 35.13% reduction in PET effective dose and a 15.22% reduction in total effective dose (P<0.05), whereas the CT effective dose was reduced by 2.4% and the difference was not significant (P=0.0892). The doses to critical organs (gonads, breasts, thyroid, red bone marrow, lungs) in the low-dose group were significantly lower than those in the full-dose group (P<0.01). Conclusion Under the premise of meeting clinical diagnostic requirements, low-dose ¹⁸F-FDG whole-body PET/CT imaging in pediatric patients can reduce the overall radiation exposure by 15%, and decrease the doses to critical organs, including the gonads, by more than 20%.

As a common biliary disease, cholelithiasis has high incidence and recurrence rates, with negative impact on patients′ health and quality of life. The causes of cholelithiasis are complex, and recent studies have shown that microorganisms may be associated with the formation and recurrence of cholelithiasis, but the specific relationship between the two has not been fully elucidated. Bile microbiota may be related to the increase of incidence rate of gallstones. Different types of cholelithiasis have different microbial composition. Microorganisms may participate in the formation and recurrence of gallstones by influencing bile composition, promoting the formation of stone cores and other ways. The authors provide a review on the etiology and pathogenesis of cholelithiasis, classification of cholelithiasis, microenvironment of biliary microbiota, and the relationship between biliary microbiota and stone formation, aiming to provide new ideas and theoretical basis for the prevention and treatment of cholelithiasis.

Objective To explore the potential profile of body image and its influencing factors among head and neck cancer patients.Methods Convenience sampling was employed to investigate 335 head and neck cancer patients in a tertiary hospital in Shandong Province from October 2023 to May 2024.Data was collected using the patient's general information questionnaire,Body Image Scale,Medical Coping Modes Questionnaire,Perceived Social Support Scale,Comprehensive Score for Financial Toxicity based on the Patient-Reported Outcome Measures.Latent profile analysis and multivariate Logistic regression analysis were used to explore distinct profiles and influencing factor of body image in head and neck patients.Results A total of 335 valid questionnaires were collected in this study,and 95.4％of the valid questionnaires were included.Body image of patients with head and neck cancer could be divided into 3 latent profiles:body emotional stability(41.5％),body cognitive dissatisfaction(33.7％)and social behavior avoidance(24.8％).Age,location of cancer onset,stage of cancer,surgical treatment,medical coping style(facing coping,yielding coping),social support and economic toxicity were the factors influencing the latent profiles of body image in patients with head and neck cancer(P＜0.05).Conclusion There is heterogeneity in body image of patients with head and neck cancer.Medical staff should implement targeted management strategies based on the influencing factors of different profiles to reduce the body image disorders in patients with head and neck cancer,and to promote patients to better return to society.

Objective To observe the effect of Huaiqihuang granules(HQH)containing serum on the proliferation in rat glomerular mesangial cells(HBZY-1)cultured with high glucose,and to explore its possible mechanism.Methods HQH and physiological saline were administered orally to SPF grade male SD rats for preparing HQH containing serum and normal serum.HBZY-1 cells were divided into normal glucose group,high glucose group,high glucose+low,medium,and high concentration HQH drug containing serum group(HQH drug containing serum concentration was 5%,10%,and 15%,respectively).The cell proliferation rate of each group was measured by CCK-8 method,and effective HQH drug containing serum was screened for subsequent experiments;Observe the morphology of HBZY-1 cells in each group using an inverted optical microscope and take photos;Flow cytometry was used to detect the apoptosis rate;The assay kit was used to detect the activities of superoxide dismutase(SOD),catalase(CAT),glutathione peroxidase(GSH-Px),and malondialdehyde(MDA)in each group of cells;Western blot was used to detect the expression of TLR4/NF-κB/NLRP3 inflammatory pathway related proteins in each group of cells.Results Compared with the high glucose group,the 5%medicated serum group showed no significant change in cell proliferation rate,while the 10%medicated serum group and 15%medicated serum group showed a significant decrease in cell proliferation rate(P<0.05 or P<0.01).Therefore,10%and 15%concentrations of HQH medicated serum were selected as the subsequent experimental drug treatment groups.After intervention with 10%medicated serum and 15%medicated serum on HBZY-1 cells in a high glucose environment,compared with the high glucose group,the 10%medicated serum group and 15%medicated serum group showed a decrease in cell proliferation,a gradual increase in cell apoptosis,an increase in cell SOD,CAT,GSH-Px activity(P<0.05 or P<0.01),a decrease in MDA levels(P<0.01),the protein expression of TLR4,NLRP3,p-NF-κB p65 and p-IκBα significantly decreased(P<0.01).Conclusion Huaiqihuang granules containing serum can inhibit high glucose induced proliferation and induce apoptosis of HBZY-1 cells,which may be related to the inhibition of cellular oxidative stress and TLR4/NF-κB/NLRP3 mediated inflammatory signaling pathway.
