Attention deficit hyperactivity disorder （ADHD） is often accompanied by tic disorder. The core pathogenesis is considered to be ministerial fire scorching yin and internal stirring of deficient wind， which leads to disharmony between the body and spirit， resulting in clinical manifestations. The treatment principles emphasize nourishing yin fluids， calming ministerial fire， and extinguishing endogenous wind （内风）. The method of nourishing yin fluids is applied throughout the entire treatment process， commonly using ingredients such as Shudihuang （Rehmanniae Radix Praeparata）， Shanzhuyu （Corni Fructus）， Gouqizi （Lycii Fructus）， Wuweizi （Schisandrae Chinensis Fructus）， and Tusizi （Cuscutae Semen）. These are combined with approaches to harmonize the zang-fu organs， primarily including extinguishing liver wind， clearing heart fire， nourishing kidney water， and strengthening spleen earth， thereby stabilizing ministerial fire and extinguishing endogenous wind. Additionally， emotional regulation and smoothing emotional constraint are essential to improve clinical symptoms in children with ADHD comorbid with tic disorder.

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.

Objective: To explore the application method and clinical efficacy of endoscopic and computerized navigation technology in maxillofacial foreign body removal surgery, and to provide a reference for the clinical application of this technology. Methods: This study, which was approved by the Medical Ethics Committee of the hospital, retrospectively analyzed the data of five patients with maxillofacial foreign bodies who were admitted to Sun Yat-sen Memorial Hospital, Sun Yat-sen University from January 2018 to December 2024. All patients underwent preoperative CT scanning. Intraoperatively, endoscopic and computer navigation techniques were used in combination or separately according to the location, size, and adjacency of the foreign body to important neurovascular vessels. The foreign body was precisely localized by endoscopic magnification and direct visualization, and the optimal surgical path was designed and verified under the real-time guidance of computerized navigation to accurately remove the foreign body. The type of foreign body, location, length and diameter, duration of surgery, length of incision, success rate of foreign body removal, postoperative complications, and follow-up were recorded and analyzed. Results: The foreign body was successfully removed in all five patients with a success rate of 100%. The intraoperative computerized navigation system was accurate in positioning, and the alignment stability was not significantly affected by mandibular movement; the endoscope provided good illumination and exposure of the operative field. All surgical incisions were small, and no serious complications, such as foreign body residue, important neurovascular injury, or infection, occurred after surgery. One month after the operation, the patients were followed up and recovered well. Conclusion The combination of endoscopy and computer navigation or separately assisted technology can provide a clear field and real-time positioning for maxillofacial foreign body removal, effectively avoiding important anatomical structures, thus realizing safe and complete foreign body removal with minimized trauma. This assistive technology significantly improves the accuracy and safety of the operation and has clinical promotion value.

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.

Background: The genetic basis for hyperglycaemia in pregnancy remain unclear. This study aimed to uncover the genetic determinants of gestational diabetes mellitus (GDM) and investigate their applications. Methods: We performed a meta-analysis of genome-wide association studies (GWAS) for GDM in Chinese women (464 cases and 1,217 controls), followed by de novo replications in an independent Chinese cohort (564 cases and 572 controls) and in silico replication in European (12,332 cases and 131,109 controls) and multi-ethnic populations (5,485 cases and 347,856 controls). A polygenic risk score (PRS) was derived based on the identified variants. Results: Using the genome-wide scan and candidate gene approaches, we identified four susceptibility loci for GDM. These included three previously reported loci for GDM and type 2 diabetes mellitus (T2DM) at MTNR1B (rs7945617, odds ratio [OR], 1.64; 95% confidence interval [CI],1.38 to 1.96]), CDKAL1 (rs7754840, OR, 1.33; 95% CI, 1.13 to 1.58), and INS-IGF2-KCNQ1 (rs2237897, OR, 1.48; 95% CI, 1.23 to 1.79), as well as a novel genome-wide significant locus near TBR1-SLC4A10 (rs117781972, OR, 2.05; 95% CI, 1.61 to 2.62; Pmeta=7.6×10-9), which has not been previously reported in GWAS for T2DM or glycaemic traits. Moreover, we found that women with a high PRS (top quintile) had over threefold (95% CI, 2.30 to 4.09; Pmeta=3.1×10-14) and 71% (95% CI, 1.08 to 2.71; P=0.0220) higher risk for GDM and abnormal glucose tolerance post-pregnancy, respectively, compared to other individuals. Conclusion Our results indicate that the genetic architecture of glucose metabolism exhibits both similarities and differences between the pregnant and non-pregnant states. Integrating genetic information can facilitate identification of pregnant women at a higher risk of developing GDM or later diabetes.

Objective To investigate the mechanism of Shugan Zhixie Prescription in treating irritable bowel syndrome with diarrhea(IBS-D)using network pharmacology;To validate the findings through in vivo experiments.Methods Active components and potential targets of Shugan Zhixie Prescription were identified via the TCMSP database.Disease targets for IBS-D were retrieved from GeneCards,DisGeNET and OMIM databases.The intersection of drugs and disease targets was taken,and the protein interaction network was constructed by using STRING database.GO and KEGG pathways were enriched to identify the key signaling pathways of Shugan Zhixie Prescription in the treatment of IBS-D.The rat model of liver depression and spleen deficiency type IBS-D was established by the method of abnormal hunger and satiety,restraint pinch stress and intestinal perfusion of acetic acid.The rats were intervened with low-,medium-and high-dosage of Shugan Zhixie Prescription respectively for 14 days.Serum contents of diamine oxidase(DAO),interleukin(IL)-8,and IL-18 were measured by ELISA.Protein expressions and mRNA expressions of relevant targets in colonic tissue were detected using Western blot and RT-qPCR.Results A total of 26 active components and 553 targets of Shugan Zhixie Prescription were obtained,and 1 930 targets of IBS-D disease were obtained,with 184 drug-disease intersection targets.The possible mechanism was related to NF-κB,AGE-RAGE,Th17 cell differentiation and other signaling pathways.Animal experiments demonstrated that Shugan Zhixie Prescription could significantly reduce defecation frequency,fecal water content,and inflammatory cytokine levels in model rats.It markedly decreased TLR4 and NF-κB protein expressions(P<0.01),while increased AQP3,AQP8 and Occludin protein expressions in colonic tissue(P<0.01,P<0.05).Conclusion Shugan Zhixie Prescription exerts therapeutic effects on IBS-D through multiple pathways and targets,and the mechanism may be related to inhibiting TLR4/NF-κB signaling pathway and promoting intestinal barrier repair.

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 investigate the effects of sampling methods on pathological assessment of resected non-small cell lung cancer (NSCLC) specimen with tumor maximum diameter >3 cm after neoadjuvant therapy.Methods:NSCLC patients with a large tumor (diameter >3 cm) that were resected after neoadjuvant therapy from June 2020 to July 2023 were retrospectively collected in the Department of Pathology, Shanghai Pulmonary Hospital, Shanghai, China. Sampling methods of the tumor bed were performed in accordance with the international and Chinese experts recommendations for resection specimens following neoadjuvant therapy (recommended sampling method, RSM), and all remaining tumor bed lesions were completely sampled after recommended sampling (complete sampling method, CSM). The difference of pathological response assessment of residual viable tumor (RVT) between RSM and CSM was examined.Results:A total of 90 cases were identified and analyzed, including 39 cases of squamous cell carcinoma and 51 cases of adenocarcinoma, treated with neoadjuvant therapy including chemotherapy in 22 cases (24.4%), targeted therapy in 14 cases (15.6%), and chemoimmunotherapy in 54 cases (60.0%). There were 62 males and 28 females with an average age of (62.7±17.9) years. The average tumor maximum diameter was 4.3 cm (range, 3.1-8.0 cm). The average number of sampled blocks was 8 blocks (range, 5 to 16) and 15 blocks (range, 8 to 36) per case by RSM and CSM, respectively. According to the definition of major pathological response (MPR) in which RVT is ≤10%, the numbers of patients with MPR were 34 cases by RSM and 30 cases by CSM, respectively. Four cases showed inconsistent RVT between the two methods, including one case of squamous cell carcinoma and three cases of adenocarcinoma. The RVT of the four inconsistent cases was 7%, 7%, 5% and 9% (MPR by RSM), and 15%, 15%, 15% and 20% (non-MPR by CSM), respectively. The kappa values of MPR consistency evaluated by the two sampling methods were 0.893 for all cases, 0.906 for squamous cell carcinoma cases and 0.751 for adenocarcinoma cases. According to MPR cut-off of 65% for invasive primary adenocarcinoma, 24 cases and 20 cases achieved MPR by RSM and CSM, respectively. Of the four inconsistent cases, the RVT by RSM was 60% in three cases and 65% in one case (MPR), whereas the RVT by CSM was 70% in three cases and 75% in one case (non-MPR). The kappa value of the two sampling methods was 0.741.Conclusions:There is high consistency between RSM and CSM in the pathological assessment of post-treatment responses in resected NSCLC specimens with tumor maximum diameter larger than 3 cm. When the percentage of RVT cells is close to MPR, re-evaluation of the specimen is required and CSM may be necessary to accurately evaluate the degree of pathological remission, assist in clinical postoperative treatment, and predict patient prognosis.
