Objective To explore the dominant views with positive results when performing echocardiography on common congenital heart disease (CHD) in children using the seven-step screening method for pediatric echocardiography. Methods The echocardiographic data of children with atrial septal defect, patent foramen ovale, ventricular septal defect, and patent ductus arteriosus were collected from September 2021 to February 2022. The disease type distribution, view distribution, and the dominant view distribution were analyzed. Dominant view referred to the view with a high ratio of positive result images per view to the total image in each disease. Results A total of 8 353 images of 1 633 children with common CHD were collected. There were 813 males and 820 females ageed 0-7 years, including 3 613 images in 701 patients with atrial septal defect, 1 178 images in 206 patients with patent foramen ovale, 2 857 images in 576 patients with ventricular septal defect, and 705 images in 150 patients with patent ductus arteriosus. The dominant views of atrial septal defect were subxiphoid 2-chamber view (92.96%), subxiphoid 4-chamber view (85.61%), parasternal 4-chamber view (62.07%), and parasternal short-axis view (38.50%). The dominant views of patent foramen ovale were subxiphoid 2-chamber view (82.69%) and subxiphoid 4-chamber view (65.41%). The dominant views of ventricular septal defect were parasternal 5-chamber view (79.73%), parasternal short-axis view (79.41%), parasternal 4-chamber view (58.18%), and parasternal long-axis view (51.11%). The dominant view of patent ductus arteriosus was parasternal short-axis view (98.80%). Conclusion The analysis of the lesion key areas of common CHD shows that there are 4 dominant views for atrial septal defect and ventricular septal defect, 2 for patent foramen ovale, and only 1 for patent ductus arteriosus. Clarifying the dominant views of common CHD is conducive to rapid and accurate diagnosis of diseases, clinical practice, teaching and scientific research.

Based on the theory of "cold qi generates turbidity" described in the Inner Canon of Yellow Emperor （《黄帝内经》）， together with the physiological characteristics of children， who are considered to have an inherent insufficiency of the lung， spleen， and kidney， and the clinical features of recurrent refractory nephrotic syndrome （RNS）， this article proposes that the pathogenesis of RNS in children is characterized by yang deficiency with internal cold， turbidity arising from cold， latent turbidity transforming into toxin， activation by newly contracted pathogens， and turbid toxins damaging the collaterals. The core pathogenesis is identified as yang deficiency， turbidity coagulation， and collateral damage. Accordingly， the general treatment principle is warming yang and eliminating turbidity， with coordination of three methods including warming yang to strengthen the body's foundation， promoting yang to relieve constraint， and raising yang while replenishing qi. Zhenwu Decoction （真武汤） is employed as the basic prescription with modification according to syndrome differentiation， to achieve an effect eliminating turbidity and arresting leakage， restoring kidney function by unblocking the collaterals， and consolidating recovery to prevent relapse.

OBJECTIVE To establish a high-performance liquid chromatography （HPLC） fingerprint and content determination method for Phellodendron chinensis ， and to evaluate its quality combined with chemometrics analysis.METHODS The HPLC fingerprints of 30 batches of P. chinensis were established by the Similarity Evaluation System for Chromatographic Fingerprint of Traditional Chinese Medicine （2012 Edition）， and similarity evaluation and common peak identification were carried out.The contents of phellodendrine hydrochloride， magnoflorine， chlorogenic acid， 5- O -feruloylquinic acid， 4- O -feruloylquinic acid， 3- O -feruloylquinic acid， jatrorrhizine hydrochloride，and berberine hydrochloride were determined by the same HPLC method. Hierarchical cluster analysis （HCA）， principal component analysis （PCA）， and partial least squares-discriminant analysis （PLS-DA） were performed using the contents of the above eight components as variables.RESULTS A total of 16 common peaks were identified in the HPLC fingerprints of 30 batches of samples， and 8 common peaks were identified， including phellodendrine hydrochloride， magnoflorine， chlorogenic acid， 5- O -feruloylquinic acid， 4- O -feruloylquinic acid， 3- O -feruloylquinic acid， jatrorrhizine hydrochloride，and berberine hydrochloride. The similarity of 30 batches of samples ranged from 0.989 to 1.000. The results of content determination showed that the contents of eight components such as phellodendrine hydrochloride were 10.108-22.745，2.598-5.529，6.250-13.942，4.956-12.433，10.895-27.384，43.248-78.924， 0.428-1.154， 81.827-153.066 mg/g， respectively. The HCA results showed that 30 batches of samples were clustered into 3 categories：S1-S10 as one category， S11-S23 as one category，and S24-S30 as one category. The PCA results showed that the comprehensive scores of 10 batches of samples from the Sichuan production area （S1-S10） ranked among the top 10. The PLS-DA results showed that the variable importance in projection values of berberine hydrochloride， 3- O -feruloylquinic acid， chlorogenic acid and phellodendrine hydrochloride were greater than 1.CONCLUSIONS The HPLC fingerprint and content determination methods established in this study are stable and reliable. Chemometric analysis based on multi-component content data can be used for the quality evaluation of P. chinensis . Berberine hydrochloride， phellodendrine hydrochloride，and 3- O -feruloylquinic acid may be the differential markers affecting the overall quality of P. chinensis .

Carbon ion radiotherapy(CIRT)is an advanced radiotherapy method with unique physical and biological properties.It increases the dose to the tumor target area while providing better protection to normal tissues.CIRT can be used for hypoxic tumors resistant to photon radiotherapy.It also has the potential superiority of inducing immune responses and can produce the"abscopal effect"when com-bined with different immunotherapies.Radioimmunotherapy can not only ablate tumors at the irradiated site but also partially control dis-tant metastases at the unirradiated site.However,the underlying mechanism has not been fully elucidated.Due to the protection of the tu-mor microenvironment,tumors can sometimes be difficult to completely clear through CIRT-mediated anti-tumor immunity;this can also in-dicate functional limitations of some immune organs after CIRT.Therefore,this study reviewed the impact of CIRT on both innate and adapt-ive immune responses.It also examined the relationship between different radiation doses/fractions and immune protein expression,as well as compared the differences in imaging techniques between carbon ion radiotherapy and traditional radiotherapy.We have also proposed future directions to enhance the superiority of CIRT.This study aimed to provide a strong theoretical basis for improving the efficacy of CIRT and its combination therapy,ultimately benefiting more patients with cancer.

Objective:To investigate the effect of ginsenoside octanoate(Rh2-O)on inducing immunogenic cell death in hepa-tocellular carcinoma cells and its molecular mechanism.Methods:Effects of ginsenoside caprylate(Rh2-O)and autophagy inhibitor 3-MA on the activity of hepatocellular carcinoma cells were detected by CCK-8 assay.The effect of Rh2-O on CRT membrane eversion in Hepa1-6 cells were detected by immunofluorescence assay.Rh2-O treated mouse hepatocellular carcinoma cells were used to pre-pare a tumor vaccine for in vivo vaccination experiments in mice.Extracellular ATP levels were detected in real-time.The expression of autophagy-related genes and proteins were measured by real-time fluorescence PCR and Western blot,and the mitochondrial morphol-ogy and co-localization with autophagy proteins were observed by laser confocal microscopy.Results:Rh2-O showed strong cytotoxicity to Hepa1-6 cells[cell viability:(58.54±3.56)%]at a concentration of 150 μmol/L,and a large amount of CRT was observed on the surface of the cell membrane.The tumor emergence rate was 36.36%in the vaccinated group and 100%in the control group.The tumor vaccine prepared by Rh2-O effectively protected mice from the same type of tumor attack;Rh2-O induced an increase in the level of cellular secreted ATP(P<0.05),the mRNA of autophagy-related genes ATG3,p62,LC3 expression levels and autophagy-associated proteins LC3A and LC3B expression levels were increased(P<0.05),and co-localization of mitochondria with autophagy proteins was significantly increased(P<0.05).In addition,Rh2-O action on 3-MA pretreated hepatocellular carcinoma cells resulted in a signifi-cant decrease in extracellular ATP levels(P<0.001).Conclusion:Rh2-O may induce immunogenic cell death by inducing autophagy in hepatocellular carcinoma cells.

Radiopharmaceuticals operate by combining radionuclides with carriers. The radiation energy emitted by radionuclides is utilized to selectively irradiate diseased tissues while minimizing damage to healthy tissues. In comparison to external beam radiation therapy, radionuclide drugs demonstrate research potential due to their biological targeting capabilities and reduced normal tissue toxicity. This article reviews the applications and research progress of radiopharmaceuticals in cancer treatment. Several key radionuclides are examined, including ²²³Ra, ⁹⁰Y, Lutetium-177 (¹⁷⁷Lu), ²¹²Pb, and Actinium-225 (²²⁵Ac). It also explores the current development trends of radiopharmaceuticals, encompassing the introduction of novel radionuclides, advancements in imaging technologies, integrated diagnosis and treatment approaches, and equipment-medication combinations. We review the progress in the development of new treatments, such as neutron capture therapy, proton therapy, and heavy ion therapy. Furthermore, we examine the challenges and breakthroughs associated with the clinical translation of radiopharmaceuticals and provide recommendations for the research and development of novel radionuclide drugs.

Objective To observe the correlations of image manifestations of organ damage and clinical characteristics of heat stroke.Methods Totally 46 patients with heat stroke were retrospectively enrolled.Based on the presence or absence of image manifestations of heat stroke related organ damage on head MRI and chest-abdominal CT and combined with sequential organ failure assessment(SOFA),the patients were divided into organ damage positive group(positive A,images showed clear manifeatations of organ damage and the corresponding SOFA≥2)and organ damage negative group(negative B,images showed no obvious organ damage or the corresponding SOFA＜2).Clinical data,laboratory indicators and treatment outcomes were compared between groups.Univariate and multivariate logistic analyses were used to explore the correlations of image manifestations of organ damage and clinical characteristics of heat stroke.Results Among 46 cases,26 were classified as positive group A and 20 as negative group.There were significant differences of patients' age,gender,Glasgow coma scale(GCS)and heart rate at admission,thrombin time,D-dimer,lactate dehydrogenase,partial pressure of carbon dioxide,lactic acid,myoglobin,platelet count(PLC),interleukin-6 and serum creatinine before treatment,as well as time of hospital stay and post-treatment outcomes between groups(all P＜0.05).GCS score,PLC levels and time of hospital stay of heat stroke patients were all correlated with image manifeations of organ damage(OR=0.592,0.729,1.532,all P＜0.05),among which GCS score and time of hospital stay were independently associated with image manifeations of organ damage(OR=0.607,1.448,both P＜0.05).Conclusion Image manifeations of organ damage was correlated with GCS score and time of hospital stay in patients with heat stroke.

Objective:To investigate the sleep status of conscious patients in the ICU, their perception of ICU environmental stressors, and the correlation between the two, providing a basis for nursing interventions.Methods:A convenience sampling method was used to recruit 120 conscious patients admitted to Zhongshan Hospital, Fudan University for the first time to the ICU from August 2022 to January 2023 for the study. Data were collected using a general information questionnaire, the Intensive Care Unit Environmental Stressor Scale (ICUESS), and the Richards-Campbell Sleep Questionnaire (RCSQ). Multiple linear regression analysis was performed to identify factors influencing sleep quality in conscious ICU patients.Results:The total RCSQ and ICUESS scores of 120 conscious ICU patients were 36.0 (12.3, 60.8) and 76.0 (69.0±84.0), respectively. The primary stressors identified by patients were "inability to fall asleep" "thirst" and "restraint by medical tubing". Multiple linear regression analysis showed that the treatment environment, one's own experience and noise were significant factors affecting sleep quality in conscious ICU patients ( P<0.05) . Conclusions:The overall sleep quality of conscious ICU patients was poor and closely related to their perceived level of ICU environmental stressors. ICU medical staff should focus on optimizing the treatment environment, noise and patients' own experience to improve their sleep quality.
