Childhood obesity is a chronic nutritional disorder caused by multiple factors that result in excessive total body fat and/or increased local fat content and abnormal fat distribution，sometimes accompanied by complications such as metabolic syndrome. The obesity caused by other factors excluding the secondary factors like genetics or metabolism is referred to as simple obesity. The incidence of childhood obesity in China is showing a trend toward younger ages and rapid growth，posing a serious threat to people's health and creating a heavy economic burden. Therefore，it is urgent to control and effectively intervene in childhood obesity. Traditional Chinese herbal medicine has long been a representative of internal treatment and shows effectiveness and advantages in the clinical treatment of childhood obesity. However，there is currently a lack of a comprehensive set of diagnostic and treatment standards，as well as evidence-based clinical practice. In order to improve clinical physicians' understanding of this disease and to promote the standardization and rationalization of herbal treatment，experts in clinical Chinese and Western medicine，nutrition，and methodology from across China were invited. On the basis of expert experience and current evidence，the Grading of Recommendations Assessment，Development，and Evaluation （GRADE） method was used to grade the evidence and recommendations. After two rounds of Delphi expert consultations，the guideline secretariat revised and refined the materials based on expert opinions. Ultimately，14 entries of expert consensus and recommendations were formulated，highlighting the advantages and characteristics of herbal treatment for childhood obesity，clarifying syndrome differentiation，medication，treatment cycles，and combination therapy plans for common clinical syndromes，thereby providing more treatment ideas in clinical practice and better leveraging therapeutic advantages.

Objective:To explore the application value of transcranial ultrasound(TCS)in evaluating the third ventricle in cognitive impairment associated with Parkinson's disease(PD).Methods:A cross-sectional study was conducted.A total of 100 patients with PD, hospitalized and diagnosed in the Department of Neurology at Beijing Hospital from January 2021 to May 2024, were included in the study.Due to limitations related to the temporal window, the third ventricle could not be visualized in 2 patients(2%).Consequently, a total of 98 PD patients underwent TCS and cranial magnetic resonance imaging(MRI)examinations.Based on the Montreal Cognitive Assessment(MoCA)score, the PD patients were classified into three groups: normal cognitive function(18 cases), mild to moderate cognitive impairment(62 cases), and severe cognitive impairment(18 cases).The clinical manifestations and ultrasonic image characteristics of patients in each group were compared.Results:TCS and MRI demonstrate strong consistency in measuring the width of the third ventricle, with an intraclass correlation coefficient(ICC)of 0.783.Patients with severe cognitive impairment exhibit a wider third ventricle compared to those with normal cognitive function( P=0.002), and the width in patients with severe cognitive impairment is also greater than that in patients with moderate cognitive impairment( P=0.016).Additionally, the width of the third ventricle in individuals with PD shows a positive correlation with age( P<0.001), but it does not correlate with disease duration, the area of substantia nigra hyperecho, midbrain area, MoCA scores, Mini-Mental State Examination(MMSE)scores, Hamilton Anxiety Rating Scale(HAMA)scores, or Hamilton Depression Rating Scale(HAMD)scores( P>0.05).No statistically significant difference was found in the area of bilateral substantia nigra hyperecho among the three groups( P>0.05).Multiple linear regression analysis indicated that disease duration, third ventricle width, midbrain area, HAMD, and HAMA do not affect MoCA( P>0.05), while MMSE scores have a statistically significant impact on MoCA( P<0.001). Conclusions:The measurement of the third ventricle using TCS is valuable for evaluating cognitive decline.In patients with PD who exhibit severe cognitive impairment, the third ventricle is often widened; however, the width of the third ventricle does not correlate with cognitive performance.

Objective To observe the value of intratumoral and peritumoral ROI-based CT radiomics combined with clinical and imaging features for preoperatively predicting renal capsule invasion of clear cell renal cell carcinoma(ccRCC).Methods Totally 105 ccRCC patients were retrospectively collected and divided into invasion group(n=70)and non-invasion group(n=35)according to post operation pathology,also divided into training set(n=84,including 56 cases of invasion group and 28 of non-invasion group)and test set(n=21,including 14 cases of invasion group and 7 of non-invasion group)at a ratio of 8∶2.A clinical-imaging model was constructed based on clinical and CT features being significantly different between groups.Radiomics features related to renal capsule invasion were extracted and selected from intratumoral and of 1-6 mm peritumoral ROI on unenhanced phase(UP),corticomedullary phase(CMP)and nephrographic phase(NP)CT images,respectively.The optimal algorithm was selected among 6 machine learning algorisms based on CMP intratumoral ROI.With the optimal and selected features,single intratumoral or peritumoral models,combined intratumoral and peritumoral models within the same phase and combined pairwise models within the same range across different phases images were established.The best performing radiomics model was chosen and integrated with clinical and imaging features to form a combined model.Receiver operating characteristic(ROC)curves were drawn,the area under the curve(AUC)was calculated to evaluate the efficacy of model for predicting renal capsule invasion of ccRCC,which were compared using DeLong's test.Results Hypertension,presence of clinical symptoms and high enhancement degree on CMP images were all independent predicting factors for renal capsule invasion of ccRCC,which were used to establish clinical-imaging model.Support vector machine(SVM)was the optimal algorithm.CMP peritumoral 3 mm model,CMP intratumoral model,NP peritumoral 4 mm model,NP intratumoral+peritumoral 4 mm model and CMP peritumoral 3 mm+NP peritumoral 3 mm model showed higher performance than the others,with AUC being not significantly different(all P＞0.05).CMP peritumoral 3 mm model was the optimal radiomics model,with the highest AUC(0.898)in test set.The combined model demonstrated superior AUC(0.979)in training set compared to both clinical-imaging model and the optimal radiomics model alone(both P＜0.05),while in test set(AUC 0.918)showed comparable performance with the latter two(both P＞0.05).Conclusion CT-based peritumoral radiomics models were equally effective for preoperatively predicting renal capsule invasion of ccRCC.Combining with clinical and imaging features might further enhance diagnostic performance.

Objective To investigate the value of MRI of the sternal end of clavicle in bone age assessment in Chinese population,especially its applicability in the determination of criminal responsible age.Methods A total of 431 patients aged from 10.00 to 29.99 years with neck or chest MRI were retrospectively collected.According to the Schmeling grading method,the epiphyseal development of the clavicle MRI was divided into five grades.The consistency of methods was evaluated.The correlation and general descriptive analysis between MRI grades and age was analyzed.The sex difference was analyzed.Curve fitting was used to establish a nonlinear model between age and grades.Results The grades of clavicle MRI showed a significant age-related trend(Figure 2),and the correlation was 0.861(0.887 in males and 0.840 in females).Except for grade 1,there was no significant difference between males and females in other grades.The minimum age of male grade 3 was greater than 14 years old,and the minimum age of female grade 3 was greater than 16 years old.The minimum age in grade 4 and grade 5 was over 18 years old in both sexes.The best curve fitting model was cubic model for both sexes(R2=0.805 for men and 0.722 for women).Conclusion Clavicle MRI can be used for the assessment of bone age in Chinese population.Complete epiphyseal plate closure can be used as a reliable indicator for the determination of age at 18 years old,and it is expected to achieve radiation-free forensic bone age assessment.
