Childhood simple obesity has become a significant public health issue in China. Modern medicine primarily relies on lifestyle interventions and often suffers from poor long-term compliance， while pharmacological options are limited and associated with potential adverse effects. Traditional Chinese Medicine （TCM） has a long history in the prevention and management of this condition， demonstrating eight distinct advantages， including systematic theoretical foundation， diversified therapeutic approaches， definite therapeutic efficacy， high safety profile， good patient compliance， comprehensive intervention strategies， emphasis on prevention， and stepwise treatment protocols. Additionally， TCM is characterized by six distinctive features： the use of natural medicinal substances， non-invasive external therapies， integration of medicinal dietetics， simple exercise regimens， precise syndrome differentiation， and diverse dosage forms. By combining internal and external treatments， TCM facilitates individualized regimen adjustment and holistic regulation， demonstrating remarkable effects in improving obesity-related metabolic indicators， regulating constitutional imbalance， and promoting healthy behaviors. However， challenges remain， such as inconsistent operational standards， insufficient high-quality clinical evidence， and a gap between basic research and clinical application. Future efforts should focus on accelerating the standardization of TCM diagnosis and treatment， conducting multicenter randomized controlled trials， and fostering interdisciplinary integration， so as to enhance the scientific validity and international recognition of TCM in the prevention and treatment of childhood obesity.

The core pathogenesis of attention deficit hyperactivity disorder （ADHD） lies in deficiency， stasis and stagnation. Deficiency arises from kidney essence depletion and spleen dysfunction in transportation and transformation， leading to inadequate nourishment of the marrow sea. Stasis caused by qi deficiency leads to obstruction in channels and collaterals， resulting in obstructed marrow transport. Stagnation is associated with the excess of the five minds transforming into fire， which scorches the brain orifices and leads to loss of control over marrow utilisation. Based on this， a "supplementation-unblocking-regulation" therapeutic approach is proposed. For deficiency， the focus is on supplementing kidney and fortifying spleen， and replenishing the marrow sea. For stasis， the priority is to unblock and open the orifices， and clear the marrow channels. For stagnation， the core is to clear fire and contain the mind， regulate and restore vital activity. In clinical practice， it is necessary to identify the primary and secondary pathogenic mechanisms and apply dynamic， combined treatment， integrating Chinese herbal medicine， acupuncture， and guiding exercises throughout the process， aiming to provide a reference for the diagnosis and treatment of ADHD with traditional Chinese medical.

ObjectiveTo analyze the epidemiological characteristics of long COVID and to investigate its main influencing factors by examining individuals infected with SARS-CoV-2 between March and June 2022 in two communities in Shanghai, to lay the foundation for further research on the mechanism and clinical treatment of long COVID, and to provide the basis for the development of inexpensive, convenient, and feasible prevention and intervention strategies. MethodsA cross-sectional study was conducted, enrolling 6 410 individuals infected with SARS-CoV-2. Data were collected through a questionnaire survey. The incidence and common symptoms of long COVID were analyzed, along with their associations with demographic characteristics, medical history, and behavioral factors. A logistic regression model was used to identify the major factors associated with the development of long COVID symptoms. ResultsThe overall incidence rate of long COVID among the study population was 13.9%. The most commonly reported symptoms included fatigue (65.1%), attention disorders (23.1%), and cough (16.9%). The analysis showed that having underlying chronic diseases (OR=2.580, 95%CI: 2.165‒3.074), a history of allergies (OR=1.418, 95%CI: 1.003‒1.971), current smoking (OR=1.461, 95%CI: 1.013‒2.079), ever smoking (OR=2.462, 95%CI: 1.687‒3.551), a greater number of symptoms during the acute phase [1 symptom (OR=1.778, 95%CI: 1.459‒2.162), 2 symptoms (OR=2.749, 95%CI: 2.209‒3.409), ≥3 symptoms (OR=7.792, 95%CI: 6.333‒9.593)] and aggravated symptoms during the acute phase (OR=1.082, 95%CI: 1.070‒1.094) were factors associated with a higher risk of developing long COVID symptoms. Additionally, individuals who had consumed alcohol in the past year (OR=1.914, 95%CI: 1.344‒2.684) were more prone to objective long COVID symptoms. Among individuals under 50 years of age, females (OR=1.427, 95%CI: 1.052‒1.943) were more likely to develop objective long COVID symptoms. ConclusionThis study has identified the diversity of long COVID symptoms, which involve multiple organs and systems, including fatigue, attention disorders, cough, and joint pain. It has also revealed associations between long COVID and various demographic factors (e.g., age, gender), personal medical history (e.g., underlying chronic diseases, history of allergies), acute-phase characteristics (e.g., number and severity of symptoms), and behavioral factors (e.g., smoking, alcohol consumption). These findings highlight the need for further research and ongoing surveillance of long COVID and may inform the development of more targeted health management strategies for specific populations.

Objective To explore the value of MR modulated flip angle technique in refocused imaging with extended echo train(MATRIX)contrast enhanced(CE)T1-weighted fluid attenuated inversion recovery(T1 FLAIR)for detecting skull metastases.Methods Forty-four patients with malignant tumors who underwent head MR scanning for screening skull metastasis were prospectively enrolled,and skull metastasis were then confirmed by pathology or imaging examinations,including MRI,CT,radionuclide bone imaging(BS),PET/CT and follow-up.Head MATRIX CE-T1 FLAIR(group A),3D gradient recalled echo_fast spin echo with magnetization preparation(GRE_fsp)CE-T1 FLAIR(group B)and fast spin echo(FSE)CE-T1 FLAIR(group C)images of all 44 cases were acquired.The subjective scores(including images quality and diagnostic confidence)and objective evaluation results of images were compared among groups.Taken BS or PET/CT results as standards,the efficacy of 3 kinds of images for detecting skull metastases was calculated.Results The subjective scores of images quality and diagnostic confidence,as well as signal-to-noise ratio(SNR)in group A and C were all higher than those in group B(all P＜0.001),and signal intensity(SI)metastases in group A was higher than those in group B and C(both P＜0.05).No significant difference of subjective score and SNR was found between groups A and C,nor of SImetastases between groups B and C(all P＞0.05).Totally 102 skull metastases were diagnosed with PET/CT or BS,while 129,151 and 115 lesions were detected in group A,B and C,respectively,with accuracy rate of 79.07%(102/129),67.55%(102/151)and 88.70%(102/115),respectively.Conclusion MATRIX CE-T1 FLAIR sequence could be used to detect skull metastases.

Objective To investigate the predicting value of cardiac magnetic resonance feature tracking(CMR-FT)for adverse left ventricular remodeling(ALVR)in patients with acute anterior wall ST-segment elevation myocardial infarction(STEMI).Methods The clinical data and cardiac magnetic resonance(CMR)images of 161 acute anterior wall STEMI patients within 1 week and 6 months after emergency percutaneous coronary intervention(PCI)were retrospectively analyzed.ALVR was defined as an increase of left ventricular end-diastolic volume(LVEDV)over 20％at the second CMR examination compared to the baseline.The CMR parame-ters were analyzed by CVI42 post-processing software.The logistic regression analysis was used to screen the independent predictors of ALVR,and the receiver operating characteristic(ROC)curve was used to evaluate the predictive efficiency of ALVR.Results The incidence of ALVR at 6 months was 21.7％(35/161).The logistic regression analysis showed that the left ventricular global circumferential strain(LVGCS)and right ventricular global longitudinal strain(RVGLS)at baseline were independent predictors for ALVR(P＜0.001).When LVGCS was-13.89％and RVGLS was-15.07％at baseline,the sensitivity of predicting ALVR was 0.714 and 0.743,the specificity was 0.833 and 0.810,and the area under the curve(AUC)was 0.806 and 0.835,respectively.The sensitivity of LVGCS combined with RVGLS in predicting ALVR was 0.802,the specificity was 0.952,and the AUC was 0.888.The DeLong test showed that the AUC of LVGCS com-bined with RVGLS in predicting ALVR was significantly higher than that of individuals,and the difference was statistically significant(P＜0.05).Conclusion The LVGCS and RVGLS at baseline are independent predictors for ALVR in patients with acute anterior wall STEMI,their combination can significantly improve the pre-dictive efficiency of ALVR in these patients.

Nonalcoholic steatohepatitis （NASH） is a chronic liver disease with the main pathological features of hepatic steatosis， inflammatory cell infiltration， and interstitial fibroplasia， and it is an important risk factor for liver fibrosis， liver cirrhosis， and hepatocellular carcinoma. NOD-like receptor protein 3 （NLRP3） inflammasome is the core of innate immunity， and the abnormal activation of NLRP3 inflammasome is closely associated with the development and progression of NASH， which involves multiple links such as inflammatory response and oxidative stress. A large number of studies have shown that the active ingredients of traditional Chinese medicine （TCM） and TCM compound prescriptions can improve oxidative stress， regulate lipid metabolism， and alleviate liver inflammation by regulating NLRP3 inflammasome. TCM treatment applied in clinical practice has achieved a good therapeutic effect， while inflammasome is one of the key pathways or targets for TCM in improving NASH. This article reviews the mechanism of action of NLRP3 inflammasome in NASH and the research advances in TCM intervention of NLRP3 inflammasome， in order to provide ideas for the clinical TCM treatment of NASH， as well as reference targets and research directions for the research and development of new TCM drugs.

ObjectiveTo analyze the epidemiological characteristics and influencing factors of SARS-CoV-2 reinfection by conducting follow-up investigations among community residents who experienced their first SARS-CoV-2 infection between March and June 2022, so as to provide a scientific basis for predicting future epidemic trends and adjusting prevention and control strategies. MethodsA cohort study was conducted in Xuhui District, Shanghai. A total of 1 208 individuals with a documented primary SARS-CoV-2 infection between March and June 2022 were enrolled and followed-up longitudinally. Data were collected using structured questionnaire surveys to assess the reinfection rate, incidence density, and clinical manifestations of SARS-CoV-2 reinfection. A logistic regression model was used to analyze the influencing factors of SARS-CoV-2 reinfection. ResultsA total of 497 SARS-CoV-2 reinfection cases were observed among the 1 208 research subjects, with a reinfection rate of 41.14% and an incidence density of 0.63 cases per 1 000 person-days. The cumulative reinfection rates at 6, 9, 12, 15, and 18 months following the initial infection were 0.08%, 15.31%, 19.04%, 33.53%, and 38.25%, respectively. Compared with the primary infection, reinfection was more likely to be symptomatic, with a greater severity of fever, dry cough, sore throat, and runny nose. Being female, younger age, and symptom duration ≥7 days during the primary infection were identified as influencing factors for SARS-CoV-2 reinfection, while a higher socioeconomic status can reduce the risk of SARS-CoV-2 reinfection. ConclusionSARS-CoV-2 reinfection is relatively common and often symptomatic. Age, gender, income level, and the duration of symptoms during the primary infection are identified as infuencing factors for SARS-CoV-2 reinfection. Continuous monitoring of reinfection in the population is recommended, along with the development of effective strategies to mitigate the impact of reinfection.
