The core aberrant behaviors of attention deficit hyperactivity disorder (ADHD) are primarily manifested as inattention, hyperactivity, and impulsivity, which are closely associated with specific neuropathological features.Virtual reality (VR) technology, leveraging its immersive, interactive, and customizable properties, demonstrates potential in ameliorating the abnormal behavioral manifestations of individuals with ADHD. This article aims to synthesize existing evidence from neurobiological mechanism research and explore the therapeutic efficacy of VR interventions in improving abnormal behavioral presentations in ADHD patients. An evidence-integrated framework posits that: (1) VR enhances inhibitory control and working memory by promoting neural plasticity remodeling within key brain regions through highly contextualized simulation tasks, thereby optimizing functional connectivity.(2) VR reduces attentional lapses and impulsive behaviors by regulating the dynamic interplay efficiency among the default mode network, executive control network, and salience network.(3) VR elevates motivational levels and cognitive flexibility by dynamically modulating dopaminergic-noradrenergic system homeostasis, synergizing with brain-derived neurotrophic factor mediated synaptic plasticity. Delving deeper into these underlying mechanisms will facilitate the optimization of multi-target VR intervention design and provide novel insights for personalized behavioral therapy in ADHD.

Proteomic characterization of plasma is critical for the development of novel pharmacodynamic bio-markers.However,the vast dynamic range renders the profiling of proteomes extremely challenging.Here,we synthesized zeolite NaY and developed a simple and rapid method to achieve comprehensive and deep profiling of the plasma proteome using the plasma protein corona formed on zeolite NaY.Specifically,zeolite NaY and plasma were co-incubated to form plasma protein corona on zeolite NaY(NaY-PPC),followed by conventional protein identification using liquid chromatography-tandem mass spectrometry.NaY was able to significantly enhance the detection of low-abundance plasma proteins,minimizing the"masking"effect caused by high-abundance proteins.The relative abundance of middle-and low-abundance proteins increased substantially from 2.54％to 54.41％,and the top 20 high-abundance proteins decreased from 83.63％to 25.77％.Notably,our method can quantify approxi-mately 4000 plasma proteins with sensitivity up to pg/mL,compared to only about 600 proteins iden-tified from untreated plasma samples.A pilot study based on plasma samples from 30 lung adenocarcinoma patients and 15 healthy subjects demonstrated that our method could successfully distinguish between healthy and disease states.In summary,this work provides an advantageous tool for the exploration of plasma proteomics and its translational applications.

Preeclampsia is a kind of idiopathic disease during pregnancy. Its pathogenesis may involve many factors, such as mother, placenta and fetus. The study found that the abnormal metabolism of blood glucose and blood lipid during pregnancy may be closely related to the onset of preeclampsia. This paper reviews the research progress of abnormal glycolipid metabolism in preeclampsia at home and abroad in order to better guide the management of related aspects during pregnancy.

Secondary lymphedema is a chronic progressive disease caused by the obstruction of lymphatic reflux, which leads to a series of secondary affection. There is no cure at present. Exploring the pathogenesis and treatment of lymphedema is based on animal models that mimic the pathophysiology of chronic lymphedema in humans. Currently, there are many known animal models of lymphedema, such as the limb lymphedema model of mice, dogs and other animals, and the rabbit ear lymphedema model. But most of them cannot induce the persistent and stable lymphedema temporarily, which lead to a deadlock in the related research progress. Therefore, it is necessary to improve and even create new animal models of lymphedema. This paper summarises the progress of relevant literature and provides references for further improving the establishment of a lymphedema animal model. It also summarise existing methods for evaluating lymphedema or lymphatic vessel function to provide an evaluation tool for modified or new animal models.

Objective:To explore one-stage total knee arthroplasty (TKA) combined with open reduction and internal fixation (ORIF) for knee osteoarthritis complicated with tibial stress fracture.Methods:The 3 patients were retrospectively analyzed who had been treated for knee osteoarthritis complicated with tibial stress fracture at Department of Orthopedics, Ganzhou District People＇s Hospital from March 2018 to March 2020. They were all female, aged from 54 to 76 years (average, 66 years). There were 2 transverse fractures and one short oblique fracture; all of them had knee varus deformity. The Hospital for Special Surgery (HSS) scores averaged 37.6 (from 28 to 50) for the left knee and 28.3 (from 22 to 39) for the right knee. One-stage TKA was performed for the articular surface while ORIF for the right tibial stress fracture for all patients. Recorded were fracture union time, HSS knee score and range of articular motion.Results:The 3 patients were followed up for 25 to 44 months (average, 32 months).The fracture union time ranged from 4 to 7 months (average, 5 months). The last follow-ups revealed no such complications as prosthesis loosening, peri-prosthesis osteolysis or joint instability. Knee varus deformity was corrected in all patients. The HSS knee scores at the last follow-up averaged 89.6 (from 88 to 91) for the left knee and 88.3 (from 85 to 90) for the right knee.Conclusion:In the treatment of knee osteoarthritis complicated with tibial stress fracture, one-stage TKA combined with ORIF can restore the function of knee joint, leading to fine curative effects.

Objective:To investigate the value of dynamic contrast-enhanced MRI enhancement amplitude for qualitative diagnosis of suspicious residual enhancing lesions after neoadjuvant therapy (NAT) in breast cancer.Methods:In total, 168 suspicious residual enhancing lesions of 168 patients who received NAT at Peking University Cancer Hospital from January 2015 to June 2016 were retrospectively analyzed and divided into non-residual cancer group ( n=59) and residual cancer group ( n=109) according to pathological findings. Then 168 suspicious residual enhancing lesions were stratified according to molecular subtype and baseline enhancing morphology. According to the breast imaging reporting and data system, the morphology of enhancing lesions, the margin of mass-like enhancing lesions, and the distribution of non-mass-like enhancing lesions on MRI before NAT were recorded. The second phase (1 min 45 s-2 min after contrast injection) was used as the early phase, and the fifth phase (5-6 min after contrast injection) was used as the late phase to measure the signal intensity and time-signal intensity curve (TIC) of suspicious residual enhancing lesions, and the signal enhancement ratio (SER) was calculated. Independent sample t-test, Mann-Whitney U test and χ 2 test were used to compare the difference of SER and clinical features between the non-residual and residual cancer groups. The receiver operator characteristic curve was used to analyze the diagnostic efficacy of SER to determine residual cancer. Results:There are statistically significant differences in invasive ductal carcinoma grade, hormone receptor status, the morphology of enhancing lesion on baseline MRI and TIC type between non-residual and residual cancer groups ( P<0.05). The SER values of the non-residual cancer group in the early [31% (23%, 61%)] and late (72%±43%) enhanced phases were significantly lower than those of the residual cancer group [49% (28%, 71%), 88%±38%, Z=-2.26, t=-2.43, P=0.024, 0.016, respectively]. Among suspicious residual enhancing lesions with hormone receptor negative status and single mass-like morphology, the SER values of the non-residual cancer group in the early (33%±16%) and late [64% (42%, 74%)] enhanced phases were significantly lower than those of the residual cancer group [59%±30%, 84% (77%, 106%), t=-2.86, Z=-3.17, P=0.008, 0.001, respectively]. The area under the curve values of SER in differentiating suspicious residual enhancing lesions were statistically different between early and late enhanced phases (0.606 and 0.637, respectively, Z=2.16, P=0.031). Conclusion:For breast cancer after NAT, it is difficult to determine the suspicious residual enhancing lesions on MRI subjectively, especially the hormone receptor negative lesions with single mass, SER can be used as an auxiliary diagnostic method, and it is necessary for the analysis of late enhancement.
