Definitive treatment of lung cancer with radiotherapy is challenging, as respiratory motion and anatomical changes can increase the risk of severe off-target effects during radiotherapy. Online adaptive radiotherapy (ART) is an evolving approach that enables timely modification of a treatment plan during the interfraction of radiotherapy, in response to physiologic or anatomic variations, aiming to improve the dose distribution for precise targeting and delivery in lung cancer patients. The effectiveness of online ART depends on the seamless integration of multiple components: sufficient quality of linear accelerator-integrated imaging guidance, deformable image registration, automatic recontouring, and efficient quality assurance and workflow. This review summarizes the present status of online ART for lung cancer, including key technologies, as well as the challenges and areas of active research in this field.

ObjectiveTo investigate the modifiable areal unit problem （MAUP） in the spatial pattern of Pseudostellaria heterophylla production regions and reveal the impact of statistical scales on the spatial distribution characteristics of this medicinal plant species. MethodsUsing multi-source data （literature records， field surveys， and statistical data）， we systematically analyzed the spatial patterns across three administrative levels （provincial， prefectural， and county scales）. Spatial autocorrelation （Moran's I） analysis， high-low clustering （Getis-Ord General G）， and hot/cold spot analysis （Getis-Ord Gi*） were employed. ResultsThe literature-based analysis showed that the production regions of P. heterophylla presented random distribution on the provincial scale and significant aggregation on the prefectural scale. The field survey data showed that the production regions displayed random distribution on the provincial scale but significant aggregation on both prefectural and county scales. The statistical data revealed that the production regions lacked spatial autocorrelation on the provincial scale but demonstrated significant aggregation on prefectural and county scales. ConclusionMAUP effects have substantive implications for understanding and decision-making in the arrangement of medicinal plant production regions. The county scale proves to be the most sensitive and explanatory level for analyzing the spatial pattern of P. heterophylla production regions， providing a critical foundation for habitat modeling， suitability evaluation， and ecological cultivation planning of medicinal plants.

AIM:To investigate the therapeutic effects of botulinum toxin A(BTXA)injection versus strabismus surgery in the treatment of acute acquired comitant esotropia(AACE).METHODS:Patient records of AACE cases treated at First People's Hospital of Nantong from January 2019 to September 2023 were retrospectively analyzed in this study. Patients were categorized into either strabismus surgery or BTXA injection groups based on treatment modality. Further stratification was performed according to preoperative deviation angles [>35 prism diopters(PD)vs ≤35 PD] and age(≥18 years adult group vs <18 years adolescent group). The baseline patient characteristics were collected, deviation angles at multiple timepoints before and after treatment were measured, and stereopsis test results were documented. Through comparative analysis of therapeutic outcomes across subgroups, we systematically evaluated the efficacy of different treatment approaches.RESULTS:A total of 43 AACE patients were included. At the final follow-up, both the surgery and BTXA injection groups showed a statistically significant decrease in deviation angle compared to pretreatment measurements(P<0.001). Significant differences were noted between the two groups in terms of the cure rate of strabismus and the recovery rate of stereopsis(P<0.05). For patients with deviations >35 PD, surgery yielded significantly better outcomes than injection therapy in postoperative angle, success rate, and stereopsis recovery(P<0.05). Similarly, in patients aged ≥18 years, surgical treatment was superior to injections in reducing strabismus angle, improving success rates, and restoring stereopsis(P<0.05).CONCLUSION:Both BTXA injection and strabismus surgery demonstrate therapeutic efficacy in AACE. Surgical treatment demonstrated superior efficacy compared to BTXA injection therapy, particularly in patients with deviations >35 PD and those aged ≥18 years. For patients with angles ≤35 PD or under 18 years, BTXA injection remains a viable treatment option.

Lipid turbidity disease is a metabolic disease featuring lipid metabolism disorders caused by many factors such as social environment， diet， and lifestyle， which is closely related to many diseases in modern medicine， such as hyperlipidemia， obesity， fatty liver， atherosclerosis， metabolic syndrome， and cardiovascular and cerebrovascular diseases， with a wide range of influence and far-reaching harm. According to the Huangdi Neijing， lipid turbidity disease reflects the pathological change of the body's physiologic grease. Grease is the thick part of body fluids， which has the function of nourishing， and it is the initial state and source of important substances in the human body such as brain， marrow， essence， and blood. Once the grease of the human body is abnormal， it can lead to lipid turbidity disease. The Huangdi Neijing also points out the physiological relationship between the transportation and transformation of body fluids and the rise and fall of the spleen and stomach， which can deduce the pathological relationship between the occurrence of lipid turbidity disease and the abnormal rise and fall of the spleen and stomach functions. Lipid turbidity disease is caused by overconsumption of fatty and sweet foods or insufficient spleen and stomach endowments， leading to disorders of the function of promoting clear and reducing turbidity in the spleen and stomach. This leads to the transformation of thick grease in body fluids into lipid turbidity， which accumulates in the body's meridians， blood vessels， skin pores， and organs， forming various forms of metabolic diseases. The research team believed that the pathological basis of lipid turbidity disease was the abnormal rise and fall of the spleen and stomach and the obstruction of the transfer of grease. According to the different locations where lipid turbidity stays， it was divided into four common pathogenesis types： ''inability to distinguish between the clear and turbid， turbid stagnation in the Ying blood''， ''spleen not rising clear， turbid accumulation in the vessels''， ''spleen dysfunction， lipid retention in the pores''， ''spleen failure to transportation and transformation， and grease accumulation in the liver''. According to the pathogenesis， it could be divided into four common syndromes， namely， turbid stagnation in the Ying blood， turbid accumulation in the vessels， lipid retention in the pores， and grease accumulation in the liver， and the corresponding prescriptions were given for syndrome differentiation and treatment， so as to guide clinical differentiation and treatment of the lipid turbidity disease.

Next generation sequencing (NGS) technology is playing an increasingly important role in the diagnosis of genetic diseases. Whole exome sequencing (WES), which targets the coding regions of the genome, has been widely used in the diagnosis of genetic diseases for its low cost and high efficiency. However, compared to conventional methods, the Next Generation Sequencing (NGS) process is intricate, and there is variability in the expertise of data analysts and variant interpreters, which may lead to inconsistencies in the outcomes. To ensure the quality of testing and enhance the diagnostic rate of diseases, this consensus has provided recommendations regarding the laboratory setup, operational procedures, data analysis, result interpretation, and quality control for WES, with an aim to standardize its application in the detection of genetic disorders.

Objective:To investigate the imaging characteristics of clear cell acanthoma (CCA) by dermoscopy and reflectance confocal microscopy (RCM) .Methods:A retrospective analysis was conducted on 12 patients diagnosed with CCA through histopathological examination at the Department of Dermatology, Wuhan No.1 Hospital, from 2020 to 2024. Dermoscopic and RCM features of these cases were summarized.Results:Among the 12 CCA patients, 3 were males and 9 were females, and they were aged 50.08 ± 10.43 years. Clinically, CCA lesions were typically presented as red or brown papules or nodules with well-defined borders, ranging in diameter from 3 mm to 2 cm. Histopathological examination showed that the tumor manifested as psoriasiform or papillary hyperplasia with a thickened spinous layer and a distinct boundary surrounded by the normal skin; proliferating cells were larger with lightly stained cytoplasm; neutrophil infiltration was observed in the epidermis, and vascular dilation was observed in the dermal papillae and superficial dermis; periodic acid-Schiff staining revealed abundant glycogen in the cells. In 10 patients examined by dermoscopy, dotted, globular, or glomerular vessels were arranged in a beaded pattern in all the 10 patients, and collar-like scales were seen at the edges of the lesions in 6 patients. In 6 patients examined by RCM, RCM images all revealed epidermal hyperplasia, thickened spinous layers, large keratinocytes with enlarged nuclei and abundant cytoplasm that blended in with the intercellular demarcations, disordered honeycomb structure of the epidermis, and dilation and up-thrust of blood vessels in the dermal papillae and superficial dermis; segmented cell infiltration was observed in the epidermis of 4 patients. As measured, the longest diameters of cells in the upper part of the CCA spinous layer ranged from 30.25 μm to 35.13 μm; the longest diameters of spinous layer cells at the CCA follicles (19.39 ± 2.93 μm) were significantly lower than those of the surrounding spinous layer cells (30.95 ± 5.66 μm, t = 5.73, P < 0.001) . Conclusions:CCA presents a distinctive vascular pattern on dermoscopy, and the majority of histological features can be visualized by RCM. Dermoscopy and RCM can be relatively reliable auxiliary diagnostic methods for CCA.

Objective To investigate the role of matrix GLA protein(MGP)in the pathogenesis of idiopathic calcium oxalate kidney stones(ICOS),and to find potential biomarkers for early diagnosis and disease evaluation.Methods A total of 120 patients admitted to our hospital from September 2021 to September 2023 were prospectively included,of which 60 patients with ICOS were in the calculus group and 60 patients without calculus were in the control group.Serum biochemical indexes and immunohistochemical scores of the two groups were detected,urinary MGP levels were determined by ELISA,and MGP mRNA and protein expression in renal papilla tissues were detected by qPCR and Western blot.The independent risk factors of ICOS were screened by Logistic regression analysis,and the prediction model was drawn by nomogram.Results Compared with control group,urinary MGP content in calculus group was decreased[(1 805.91±244.44)pg/ml vs.(2 014.79±252.14)pg/mnl,P＜0.05).Expression of MGP mRNA and MGP protein in renal papillae decreased(0.89±0.15 vs.1.00±0.00,P=0.001)and decreased(0.87±0.18 vs.1.00±0.00,P＜0.05).MGP immunohistochemical scores of renal tissue were decreased[4(2-6)scores vs.6(4-8)scores,P＜0.001].Multivariate analysis showed that urinary calcium(OR=1.370),urinary MGP(OR=1.127),renal papilla MGP relative expression level(OR=27.532)and renal tissue MGP immunohistochemical score(OR=1.359)were independent risk factors for ICOS.Area under ROC curve of the nomogram prediction model built based on the above factors is 0.839,indicating that the model has good differentiation ability in risk prediction.Conclusion MGP is closely related to the pathogenesis of ICOS.Urinary and renal tissue MGP levels may be potential biomarkers for early diagnosis and disease assessment of ICOS.

Genetic factors are often involved in the pathogenesis of young adult stroke, and its subtype, atherosclerotic type of large arteries, may be caused by a combination of genetic and environmental factors, but little is known about its underlying pathogenesis. To provide clues for better understanding of identifying relevant stroke etiological genetic factors and adopting effective preventive strategies, the role of genetic factors in atherosclerosis and related risk factors was described, and the possible genetic mechanisms of large-artery atherosclerotic stroke in young people were explored, which may be further investigated in future research in the following areas: etiological typing of stroke in young people and the related genetic mechanisms; modifiable vascular risk factors and the development of secondary prevention strategies; high-resolution vascular imaging magnetic resonance imaging in the etiological typing of stroke in young people and the pathogenesis of premature atherosclerosis and vulnerable plaques.

Portal hypertensive biliopathy is a secondary condition of intrahepatic and extrahepatic bile duct abnormalities caused by portal hypertension, especially in extrahepatic portal venous obstruction. Most patients may remain asymptomatic for a long time, while a few may present with symptomatic portal hypertensive biliopathy, such as obstructive jaundice, cholelithiasis with or without cholangitis, gastrointestinal bleeding, and others. Such disease is rare in clinical practice and is prone to misdiagnosis and missed diagnosis. Improper treatment can lead to serious adverse consequences. We report a case of unexpected discovery of bile duct dilation due to abdominal pain, which was ultimately diagnosed as portal hypertensive biliopathy based on the medical history, manifestations of portal hypertension, and imaging examinations, especially intraductal ultrasonography.
