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.

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.

Kaempferol(KAE),as a natural flavonoid compound,possesses multiple biological activities including po-tent anti-inflammatory,antioxidant,and immunomodulatory effects,as well as anti-cancer properties.It has demonstrated good therapeutic effects in the intervention and treatment of various ocular diseases such as fungal keratitis,corneal trans-plantation rejection,age-related macular degeneration,and diabetic retinopathy.Furthermore,the development of novel ocular drug delivery systems-such as KAE-loaded bovine serum albumin porous membranes,KAE eye drops based on poly-vinylpyrrolidone nanocomplexes,gelatin nanoparticles encapsulating KAE,and platelet-derived extracellular vesicles loaded with KAE-has improved the bioavailability of KAE,laying a foundation for expanding its applications.However,there is a lack of systematic and comprehensive reviews on the application of KAE in ophthalmic diseases.Therefore,this article summarizes the research progress,efficacy mechanisms,and novel delivery methods of KAE in ophthalmic diseases,ai-ming to provide new diagnostic and therapeutic strategies for the treatment of related ocular conditions.

Objective To investigate the CT and MRI features of giant cell reparative granuloma(GCRG)in lateral skull base.Methods The CT,MRI and clinicopathological data of 8 patients with GCRG in lateral skull base were collected and analyzed.Results All of the eight lesions were unilateral and solitary(three on the left side and five on the right side),with widespread involvement affecting two or more bony structures of the lateral skull base.All lesions showed expansile and lytic bone destruction on CT scans,the margins were clear(7/8),and the sclerotic changes could be seen at the margin of all eight lesions.On MRI,the lesions revealed heterogeneous isointense and hypointense on T1WI,and heterogeneous hypointense with focal cystic changes on T2WI,without fluid-fluid levels.The enhanced scan showed heterogeneous enhancement.Seven cases extended to the middle cranial fossa,caused com-pression of the temporal lobe brain tissue,with thickened and strengthened adjacent meninges.Conclusion The GCRG in lateral skull base has certain characteristic appearances on CT and MRI;understanding these characteristic manifestations can provide a basis for accurate diagnosis.

BACKGROUND:The cortical bone reinforcement area of bone cement in the vertebral body during percutaneous vertebroplasty for osteoporotic vertebralcompression fractures has an important influence on spinal biomechanics and clinical efficacy,but previous studies were mostly limited to the two-dimensional level. OBJECTIVE:To investigate the effect of the difference in cortical bone reinforcement of bone cement in the three-dimensional plane of the vertebral bodyon the biomechanical distribution of the vertebral body,adjacent intervertebral disc and endplate in osteoporotic vertebral compression fractures by finite element analysis during percutaneous vertebroplasty,so as to evaluate its effect.METHODS:The finite element model of percutaneous vertebroplasty for osteoporotic vertebral compression fractures of T12 vertebrae was established. The presence or absence of cortical reinforcement of bone cement was analyzed in groups from the transverse,sagittal and coronal planes. The effects of cortical reinforcement on the biomechanics of T12 vertebral cancellous bone,cortical bone,T11/T12 intervertebral disc,T12/L1 intervertebral disc,T11 lower endplate,and L1 upper endplate under different body position changes were studied.RESULTS AND CONCLUSION:(1) Under the effect of vertical compression force,percutaneous vertebroplasty cortical reinforcement with or without bone cement had no significant changes in structural stress except for the injured vertebral cortical bone. (2) The Von Mises stress value of the injured cortical bone was significantly different in human forward flexion,left/right bend,and left/right axial rotation. The maximum Von Mises stress value in the best group of cortical reinforcement was significantly smaller than that in the non-cortical reinforcement group. The Von Mises stress value showed a downward trend with extensive cortical reinforcement in the same plane. (3) It is indicated that when percutaneous vertebroplasty is performed,bone cement should be distributed as broadly and symmetrically horizontally along the cortical edge of the vertebral body as far as possible in cross section. Bone cement in sagittal plane should be widely distributed longitudinally near the upper and lower endplates and the anterior and posterior walls. Bone cement in coronal plane should be widely distributed on both sides of the midline while symmetrically touching the upper and lower endplates and lateral walls. It can effectively avoid the risk of refracture of the injured vertebra and does not increase the risk of adjacent vertebral fracture and residual discogenic pain.

Objective·To explore the value of combined diaphragm and intercostal muscle ultrasound assessment compared with conventional diaphragm ultrasound in predicting the weaning outcome in mechanically ventilated patients with sepsis.Methods·Mechanically ventilated patients with sepsis,consecutively admitted to the Department of Critical Care Medicine of Affiliated Hospital of Nantong University from October 2022 to December 2023,were selected.During the peri-weaning period,after the patient's sepsis condition improved and the patient passed the spontaneous breathing trial(SBT),ultrasound evaluation of respiratory muscles was performed by ultrasound qualified personnel with ultrasound qualification and experience in bedside ultrasound examination.Diaphragm excursion(DE),thickening fraction of diaphragm(TFD),and thickening fraction of intercostal muscle(TFic)were measured,respectively.The patients were divided into a successful weaning group(n=114)and a failed weaning group(n=24)according to the weaning results.Receiver operating characteristic(ROC)curves were used to analyze the value of diaphragm ultrasound and intercostal muscle ultrasound,alone and in combination,in predicting ventilator weaning outcome.Results·TFic and TFic/TFD were significantly higher in the failed weaning group during SBT than in the successful weaning group(all P<0.05).The areas under the ROC curve(AUROC)of DE,TFD,and TFic to predict weaning failure in mechanically ventilated patients with sepsis during the period of SBT were 0.689(0.591?0.776),0.657(0.557?0.747),and 0.769(0.676?0.846),respectively,whereas the combined indexes TFic/TFD and TFic&TFD_mix had AUROCs of 0.867(0.786?0.925)and 0.860(0.778?0.920),respectively.TFic/TFD with a cutoff value of>0.95 had a sensitivity of 86.7%and a specificity of 75.3%in predicting weaning failure,and TFic&TFD_mix with a cutoff value of>0.13 had a sensitivity of 86.6%and a specificity of 80.9%in predicting weaning failure.Moreover,the intercostal muscle ultrasonography method had an intra-observer intraclass correlation coefficient(ICC)of 0.890 and an extra-observer ICC of 0.876 for measurement reliability,which were both rated as good(P<0.001).Conclusion·Combined diaphragm and intercostal muscle ultrasonography provides a more comprehensive picture of the patient's overall respiratory muscles,and has a higher guiding value in predicting the weaning outcomes in mechanically ventilated patients with sepsis than diaphragm ultrasound alone.
