Dent disease is a rare X-linked recessive renal tubular disease characterized by low molecular weight proteinuria，hypercalcemia and nephrocalcinosis. It is also a major cause of tubular proteinuria in children. According to different causative genes，Dent disease can be divided into three types：type 1 is caused by mutations in the CLCN5 gene，accounting for about 60%-70%；type 2 is caused by mutations in the OCRL gene，accounting for about 15%-20%；type 3 has a similar clinical phenotype but no known pathogenic gene mutations. CLCN5 encodes the voltage-dependent 2Cl -/1H +exchange channel CIC-5，which is involved in proximal renal tubule endocytosis. Its mutations can cause a variety of proximal tubular dysfunction symptoms，mainly including low molecular weight proteinuria. The use of gene detection technology has resulted in an increase in reports on Dent disease year after year. At present，the specific mechanism underlying Dent disease remains unknown. This article reviews the research progress of CLCN5，hoping to provide new insight for the mechanism research of CLCN5 and the specific treatment of Dent disease type 1.

Nasal drug delivery efficiency is highly dependent on the position in which the drug is deposited in the nasal cavity. However, no reliable method is currently available to assess its impact on delivery performance. In this study, a biomimetic nasal model based on three-dimensional (3D) reconstruction and three-dimensional printing (3DP) technology was developed for visualizing the deposition of drug powders in the nasal cavity. The results showed significant differences in cavity area and volume and powder distribution in the anterior part of the biomimetic nasal model of Chinese males and females. The nasal cavity model was modified with dimethicone and validated to be suitable for the deposition test. The experimental device produced the most satisfactory results with five spray times. Furthermore, particle sizes and spray angles were found to significantly affect the experimental device's performance and alter drug distribution, respectively. Additionally, mometasone furoate (MF) nasal spray (NS) distribution patterns were investigated in a goat nasal cavity model and three male goat noses, confirming the in vitro and in vivo correlation. In conclusion, the developed human nasal structure biomimetic device has the potential to be a valuable tool for assessing nasal drug delivery system deposition and distribution.

BACKGROUND:The treatment of distal tibial fractures with soft tissue injury has always been challenging,and the new retrograde tibial nailing is a new choice.Up to now,there were few reports on the biomechanical properties between the new retrograde tibial nailing,anterograde intramedullary nailing and supercutaneous locking plate. OBJECTIVE:To explore the biomechanical stability of new retrograde tibial nailing,antegrade intramedullary nailing and supercutaneous locking plate in the treatment of distal tibial fractures with soft tissue injury using finite element analysis so as to offer a scientific foundation for clinical application. METHODS:The finite element model of transverse distal tibia fracture was established by relevant software utilizing the CT data of the tibia from a 42-year-old healthy male.Retrograde tibial nailing,antegrade intramedullary nailing and supercutaneous locking plate finite element models were assembled under the principle of fracture fixation.Finally,meshing,applying loads,and data processing were accomplished with the ANSYS 2019 software.Moreover,the stress distribution and displacement of the tibia and internal fixation of each model were compared. RESULTS AND CONCLUSION:(1)The displacement of fracture end in the three groups increased with the increase of load.In all mode loads,the average displacement of the fracture end was the least in the retrograde tibial nailing group,followed by the supercutaneous locking plate group,and the highest in the antegrade intramedullary nailing group.At 800 N vertical load,the displacement difference of the fracture end was statistically significant(P<0.05).There was no statistical significance in other load modes.(2)Under different loads,the tibial stress in the three groups was the highest in the middle of the tibia,and gradually decreased to the proximal and distal ends.The stress distribution of the tibial shaft was the highest in the retrograde tibial nailing group,followed by the supercutaneous locking plate group,and the least in the antegrade intramedullary nailing group.(3)Under different loads,the stress of the tibial stress raiser in the three groups was significantly higher in the supercutaneous locking plate group than in the other two groups,with statistical significance(P<0.05).(4)Under different loads,the stress of the fixators in the three groups was the largest in the supercutaneous locking plate group,followed by the retrograde tibial nailing group,and the minimum in the antegrade intramedullary nailing group.There were significant differences in the stress of fixator stress raiser among the three groups under different loading modes(P<0.05).(5)It is indicated that all three fixation methods have the good anti-rotation ability and axial stability.Retrograde tibial nail shows better biomechanical stability.

BACKGROUND:The treatment of distal tibial comminuted fractures with soft tissue injury has always been challenging.The new retrograde tibial nailing and supercutaneous locking plate are important treatment methods,but their strain and stress shielding at the fracture end during different periods of fracture healing and different load conditions have not been reported. OBJECTIVE:To explore the biomechanical stability of retrograde tibial nailing and supercutaneous locking plate in different periods of fracture healing by finite element analysis to offer a scientific foundation for clinical application and rehabilitation exercise. METHODS:The finite element model of distal tibial comminuted fracture was established by utilizing the CT data of the tibia from a 40-year-old healthy male.Retrograde tibial nailing,supercutaneous locking plate,and callus models were assembled in accordance with the principle of fracture fixation.The finite element analysis was performed using ANSYS software to compare the displacement of the fracture end,the stress shielding of the tibia,the stress of the callus,and the stress distribution of the tibia and the fixation device during different periods of fracture healing. RESULTS AND CONCLUSION:(1)The relative displacement of the tibial fracture decreased gradually with the healing of the fracture,and the displacement decreased significantly after 3 months.At 0 and 1 months after operation,the vertical displacement and total displacement of the supercutaneous locking plate group were higher than those in the retrograde intramedullary nail group.The Z-axis displacement(horizontal medial and lateral displacement)of the two fixation methods was more obvious than the X-axis and Y-axis,and the Z-axis displacement of supercutaneous locking plate group was the most obvious.The maximum Z-axis displacement of the two fixation methods was located on the outside of the tibia,and the minimum displacement was located on the inside of the tibia.(2)The stress shielding rate at different periods of fracture healing gradually decreased with time.The stress shielding rate of the retrograde intramedullary nail was higher than that of the supercutaneous locking plate at different stages of fracture healing.After 3 months,the stress shielding rate of the supercutaneous locking plate was reduced to about 4%,and the stress shielding rate of the retrograde intramedullary nail was reduced to about 40%.(3)The stress of the stress concentration site of the callus in the two fixation methods increased with the increase of the load,and the stress of the callus in the supercutaneous locking plate group was always greater than that in the retrograde intramedullary nail group.The maximum stress distribution of the callus was approximately equally distributed among the two modes of fixation,both in the lateral portion of the tibia.(4)As the fracture healed,the maximum stress of the tibia in the two groups decreased gradually,and the stress in the supercutaneous locking plate group was always greater than that in the retrograde intramedullary nail group.The average stress of the maximum stress area of the tibia in the supercutaneous locking plate group under 1 500 N load was 285 MPa,while that in the retrograde intramedullary nail group was 26 MPa.(5)As the fracture healed,the stress of the fixation device in the two groups decreased gradually,and the stress in the supercutaneous locking plate group was significantly higher than that in the retrograde intramedullary nail group.After 3 months,the stress of the two fixation devices decreased significantly.(6)It is indicated that in the early stage of fracture healing,the strain on the fracture end in the retrograde intramedullary nail group is small,and the maximum stress of the tibia is moderate,allowing early loaded.The fractured ends in the supercutaneous locking plate group had too large strain and too large maximum stress of the tibia,which needed to be partially loaded under protection and could not be fully loaded.In the middle and late stages of fracture healing,the tibial retrograde intramedullary nail and the supercutaneous locking plate could be completely loaded,and the stress shielding rate of the supercutaneous locking plate was significantly lower than the tibial retrograde intramedullary nail.

Aural vertigo frequently encountered in the otolaryngology department of traditional Chinese medicine （TCM） mainly involves peripheral vestibular diseases of Western medicine， such as Meniere's disease， benign paroxysmal positional vertigo， vestibular neuritis， and vestibular migraine， being a hot research topic in both TCM and Western medicine. Western medical therapies alone have unsatisfactory effects on recurrent aural vertigo， aural vertigo affecting the quality of life， aural vertigo not relieved after surgery， aural vertigo with complex causes， and children's aural vertigo. The literature records and clinical practice have proven that TCM demonstrates unique advantages in the treatment of aural vertigo. The China Association of Chinese medicine sponsored the "17th youth salon on the diseases responding specifically to TCM： Aural vertigo" and invited vertigo experts of TCM and Western medicine to discuss the difficulties and advantages of TCM diagnosis and treatment of aural vertigo. The experts deeply discussed the achievements and contributions of TCM and Western medicine in the diagnosis and treatment of aural vertigo， the control and mitigation of the symptoms， and the solutions to disease recurrence. The discussion clarified the positioning and advantages of TCM treatment and provided guidance for clinical and basic research on aural vertigo.

Objective: The study aims to investigate the impact of moderate intensity gymnastics on the development of executive function in children aged 5-6, thereby providing a theoretical foundation for exercise interventions targeting executive function. Methods: A total of 63 preschool children, randomly seleted from 3 senior classes in a private kindergarten in Shangqiu, were randomly allocated to the intervention group ( n =31) and control group ( n =32). Children in the intervention group participated in 60 minute gymnastics at a moderate intensity, three times per week, for a total duration of 12 weeks. Concurrently, myzone technology was utilized to monitor exercise intensity throughout the entire intervention period. Children in the control group maintained their regular activities. Inhibitory control (Flanker task), working memory (Empty house task), and cognitive flexibility (Dots task) were assessed before and after the experiment. Results: There was no statistically significant difference in the performance of inhibitory control, working memory, and cognitive flexibility tasks between the two groups of children before intervention ( P >0.05) .The results of covariance analysis revealed significant differences in reaction time [(782.88±24.29，805.13±23.74；719.90±119.99， 833.55± 177.87；1 042.39±72.75，1 091.29±49.42) ms] and accuracy[(73.86±7.26)%，(67.02±8.22)%;(86.36±7.63)%，( 80.50± 9.39 )%;(76.45±9.48)%，(69.59±7.66)%] across inhibitory control, working memory, and cognitive flexibility between the intervention group and the control group ( F =6.84, 4.50，4.87, 6.11, 3.74 , 5.06 , P <0.05). The intervention effect exhibited modest effects( d =0.17-0.74). Conclusions Moderate intensity gymnastics can make modest or moderate effect on improving children s executive function. Brain imaging technology can be incorporated into future research designs to investigate the underlying mechanisms of gymnastics impact on the brain structure and executive function in young children.

Objective:To explore the influence factors for futile recanalization following endovascular treatment(EVT)in patients with acute basilar artery occlusion(BAO).Methods:Clinical data of patients with acute BAO,who underwent endovascular treatment within 24 h of onset from January 2017 to November 2022,were retrospectively analyzed.The futile recanalization was defined as modified thrombolysis in cerebral infarction(mTICI)grade≥2b or 3 after successful reperfusion,but the modified Rankin Scale score>2 at 3 months after EVT.Binary logistic regression model was used to analyze the influencing factors of futile recanalization.Results:A total of 471 patients with a median age of 68(57,74)years were included and 68.9%were males,among whom 298(63.27%)experienced futile recanalization.Multivariate analysis revealed that concomitant atrial fibrillation(OR=0.456,95%CI:0.282-0.737,P<0.01),bridging thrombolysis(OR= 0.640,95%CI:0.416-0.985,P<0.05),achieving mTICI grade 3(OR=0.554,95%CI:0.334-0.918,P<0.05),arterial occlusive lesion(AOL)grade 3(OR=0.521,95%CI:0.326-0.834,P<0.01),and early postoperative statin therapy(OR=0.509,95%CI:0.273-0.948,P<0.05)were protective factors for futile recanalization after EVT in acute BAO patients.High baseline National Institutes of Health Stroke Scale(NIHSS)score(OR=1.068,95%CI:1.049-1.087,P<0.01),coexisting hypertension(OR=1.571,95%CI:1.017-2.427,P<0.05),multiple retrieval attempts(OR=1.237,95%CI:1.029-1.488,P<0.05)and postoperative hemorrhagic transformation(OR=8.497,95%CI:2.879-25.076,P<0.01)were risk factors.For trial of ORG 10172 in acute stroke treatment(TOAST)classification,cardiogenic embolism(OR=0.321,95%CI:0.193-0.534,P<0.01)and other types(OR=0.499,95%CI:0.260-0.961,P<0.05)were related to lower incidence of futile recanalization.Conclusions:The incidence of futile recanalization after EVT in patients with acute BAO is high.Bridging venous thrombolysis before operation and an early postoperative statin therapy may reduce the incidence of futile recanalization.
