Wilson disease is a copper metabolism disorder caused by mutations in the ATP7B gene， which encodes a copper-transporting ATPase β， and can result in multisystem damage. The kidneys are the third most commonly affected organs after the liver and brain. In recent years， numerous diagnostic and treatment guidelines for Wilson disease have emerged. However， most of these focus primarily on hepatic and neurological manifestations and their management， with limited coverage of renal involvement. The high incidence， low awareness， and lack of clinical specificity of Wilson disease-related renal damage （WDRD） have made early detection and intervention particularly challenging in clinical practice. To further optimize the treatment of patients with WDRD， improve clinical diagnosis and management， and enhance patients' quality of life， the Neurology Committee of the Chinese Association of Integrative Medicine， in April 2024， initiated a revision of the first expert consensus on the integrated diagnosis， treatment， and management of WDRD. This effort brought together experts in hepatology， encephalopathy （neurology）， and nephrology from many tertiary-level grade A hospitals and research institutions across China. Through comprehensive literature review and integration of frontline clinical experience， the expert group jointly developed Chinese Expert Consensus on Integrated Chinese and Western Medicine Management of Wilson Disease-related Renal Damage （hereinafter referred to as the "Consensus"）. This article provides a detailed interpretation of the Consensus in terms of diagnostic criteria， traditional Chinese medicine （TCM） syndrome differentiation and treatment classification， and comprehensive disease management， aiming to better guide clinical application. Regarding diagnostic criteria， the Consensus integrates the latest standards in China and abroad， highlights the importance of biochemical diagnosis， and compensates for the limitations of genetic testing. In the area of TCM syndrome differentiation and treatment， the Consensus refines four major syndrome types， introduces a newly defined syndrome， i.e.， phlegm， blood stasis， and heat accumulation， and elaborates on treatment principles， prescriptions， and clinical modification rules for each syndrome. For comprehensive disease management， the Consensus emphasizes multi-dimensional intervention strategies， including diet， exercise， emotional regulation， medication， and medical care， with the goal of maximally controlling the progression of renal dysfunction and helping patients achieve a better quality of life.

Objective:To delineate the surgical methodology and therapeutic paradigm of proximal tibial notch retrograde interlocking intramedullary nailing for ameliorating deformities due to osteofibrous dysplasia (OFD) in a pediatric population.Methods:A retrospective assessment was conducted on the medical records of individuals undergoing orthopedic osteotomy complemented by retrograde interlocking intramedullary nailing for OFD of the tibia from January 2016 to December 2019. The cohort comprised 15 patients, with a follow-up exceeding three years, documenting complete data sets. The patient profile included 8 males and 7 females, with 8 left-side and 7 right-side afflictions. The mean age at the time of surgery was 10.1±2.5 years, ranging from 7.1 to 12.6 years. Parameters measured were preoperative and postoperative imaging findings, which encompassed the scope of the lesion (longitudinal lesion length relative to tibial length), coronal and sagittal limb alignments, and lower limb length discrepancies.Results:The mean follow-up duration was 3.4±1.3 years, ranging from 3 to 6.6 years. Preoperatively, prominent anterior tibial arch deformities and limping were present, with 7 cases reporting fatigue-induced pain and 3 instances of pathological fractures. Post-surgery, pain symptoms were resolved, gait disturbances were improved in 9 patients, and completely resolved in 6. Tibial osteotomy or fracture healing of 15 patients averaged 3.9±0.7 months (range 3-5 months). The lesion range before surgery was 0.41±0.17, immediately after surgery was 0.38±0.17, and at the last follow-up was 0.30±0.16, with no statistical significance ( F=0.101, P=0.904). Lesion range showed no significant change throughout treatment, but radiographic density within the lesion notably increased post-surgery, suggesting bone improvement. The anterior tibial arch Angle was 28.30°±6.62° (range 20°-45°) before surgery, 4.73°±1.53° immediately after surgery, and 6.87°±1.36° at the last follow-up, with statistical significance ( F=159.739, P<0.001). A significant correction in the anterior tibial arch deformity was achieved and maintained postoperatively. There was no significant angular deformity of the tibia in the coronal plane before operation, and the medial proximal tibial angle (MPTA) and lateral distal tibial angle (LDTA) were 87.50°±1.46° and 88.30°±1.62°, 88.40°±1.46° and 88.70°±1.45° immediately after surgery, and 88.00°±1.39° and 89.10°±1.53° at the last follow-up, the differences were statistically significant ( F=1.741, P=0.188; F=1.016, P=0.371), there was no coronal deformity of tibia. The limb length discrepancy (LLD) was 0.60±0.98 cm before surgery, 0.18±0.93 cm at the last follow-up, with statistical significance ( t=0.096, P=0.761). There were no incidents of postoperative complications such as infection. Conclusion:In pediatric cases of tibial deformities attributed to osteofibrous dysplasia, a therapeutic strategy involving osteotomy for lower limb realignment, sans curettage or bone grafting of the lesion, followed by retrograde interlocking intramedullary nailing, yields favorable outcomes. Importantly, this implantation technique does not compromise the integrity of the proximal tibial epiphyseal plate in children and adolescents.

Objective:To explore the clinical effect of plating after lengthening to assist the consolidation of tibial shortening deformity in children.Methods:A retrospective analysis was conducted on 10 children with tibial shortening who were treated with circular external fixator lengthening and replacement with plate-assisted internal fixation (study group) in the Department of Pediatric Orthopedics of Tianjin Hospital from November 2019 to October 2022, and 16 children who were treated by circular external fixator only during the same period were enrolled as the external fixator group (control group). Among the 26 cases, there were 15 males and 11 females, 10 left knees and 16 right knees. The average age at the time of surgery was 8.8±4.7 years (range 5.1-13.8 years). The gender, side, age at the time of surgery were compared between the two groups. The extension length, external fixator index, healing index, Kolcaba comfort scale score, knee and ankle joint range of motion, complications and average total hospitalization costs were recorded.Results:There were no significant differences in gender, side, age at the time of surgery between the study group and control group. The extended lengths were 5.44±1.25 cm and 5.78±1.11 cm respectively without significant difference ( t=0.096, P=0.096). The external fixator index and healing index were 17.86±2.94 d/cm vs. 50.97±7.03 d/cm and 40.94±6.63 d/cm vs. 45.24±5.98 d/cm in study group and the control group with significant differences ( t=13.299, P<0.001; t=1.289, P=0.033). The Kolcaba comfort scale score of the children in the study group was higher than that of the control group, with significant difference ( t=6.821, P=0.001). Comparing the range of motion of the knee and ankle joints between the two groups, there were no significant differences before surgery, at the end of extension surgery, and at the final follow-up. When the extension end was healed, the range of motion of the knee joint was137.89°±4.40° vs. 114.09°±13.60° and ankle joint was 64.35°±5.50° vs. 56.65°±8.86° in the study group and control group with significant difference ( t=17.235, P<0.001; t=7.821, P=0.002). In the study group, 4 cases had pin tract infection, but no refracture occurred; in the control group, pin tract infection occurred in 13 cases, and refracture occurred in 2 cases after removal of the external fixator. The average total hospitalization cost of the study group was higher than that of the control group with significant difference ( t=3.745, P=0.036). Conclusion:The clinical effect of replacing plate-assisted internal fixator during the mineralization period of tibial shortening in children is reliable, and can significantly shorten the time for using external fixator. It is beneficial to the healing of the extended end of the osteotomy and the functional recovery of the knee and ankle joints. Being more comfortable for children with fewer complications, it is applicable for children who need long-distance extension, multiple extensions with limited joint function, poor tolerance for external fixators and low treatment compliance.

Objective:To summarize the imaging presentations of the fallopian canal cerebrospinal fluid leaking (FCCFL).Methods:The high resolution CT (HRCT)and MRI materials of 4 patients (4 ears) with FCCFL confirmed by surgery between August 2016 to November 2023 were retrospectively analyzed. Among these, there were 2 males and 2 females, their ages ranged from 6 to 69 years.Results:All of the FCCFL were unilateral, including 2 on the left and 2 on the right.Clinically, the patients with FCCFL suffered from clear nasal fluid flow, ear tightness, and hearing loss. On CT, all of the affected ears were depicted markedly dilatation of the proximal portion of fallopian canal(FC), the labyrinthine segment and geniculate fossa were involved in 4 cases, and involvement of tympanic segment in 1 case at the same time. The geniculate fossa in the affected side were significantly enlarged, protruding upwards into the tympanic cavity, with one case simultaneously involving the cochlea. On MRI, the hyposignal on T 1WI and hypersignal on T 2WI or water sequence like cerebrospinal fluid (CSF) were shown in the enlargement FC, without diffusion restriction, and non-enhancing with administration Gadolinium contrast.CSF-like signal effusion was shown in all of the affected tympanum, of which, the CSF-like signal effusion was demonstrated in the area along the superficial petrosal nerve, the right pterygopalatine fossa and the parapharyngeal space. The adjacent intracranial meninges were presented thickening in 3 cases. Conclusion:The imaging appearances of FCCFL present some characteristics:on HRCT, the proximal portions of the affected FC depicts markedly enlargement,especially the geniculate fossa.While they present CSF-like signal, no diffusion restriction, and no enhancement administration, Gadolinium contrast on MRI, accompanying the CSF-like signal effusion in the affected tympanum.

Objective Recent studies have indicated potential anti-inflammatory effects of glucagon-like peptide-1 receptor agonists(GLP-1RAs)on asthma,which is often comorbid with type 2 diabetes mellitus(T2DM)and obesity.Therefore,we conducted a meta-analysis to assess the association between the administration of glucagon-like peptide-1(GLP-1)receptor-based agonists and the incidence of asthma in patients with T2DM and/or obesity. Methods PubMed,Web of Science,Embase,the Cochrane Central Register of Controlled Trials,and Clinicaltrial.gov were systematically searched from inception to July 2023.Randomized controlled trials(RCTs)of GLP-1 receptor-based agonists(GLP-1RA,GLP-1 based dual and triple receptor agonist)with reports of asthma events were included.Outcomes were computed as risk ratios(RR)using a fixed-effects model. Results Overall,39 RCTs with a total of 85,755 participants were included.Compared to non-GLP-1 receptor-based agonist users,a trend of reduced risk of asthma was observed in patients with T2DM or obesity using GLP-1 receptor-based agonist treatments,although the difference was not statistically significant[RR=0.91,95%confidence interval(CI):0.68 to 1.24].Further Subgroup analyses indicated that the use of light-molecular-weight GLP-1RAs might be associated with a reduced the risk of asthma when compared with non-users(RR=0.65,95%CI:0.43 to 0.99,P=0.043).We also performed sensitivity analyses for participant characteristics,study design,drug structure,duration of action,and drug subtypes.However,no significant associations were observed. Conclusion Compared with non-users,a modest reduction in the incidence of asthma was observed in patients with T2DM or obesity using GLP-1 receptor-based agonist treatments.Further investigations are warranted to assess the association between GLP-1 receptor-based agonists and the risk of asthma.

Fibrous dysplasia of bone (FD) is a tumorlike disease characterized by intramedullary fibrosis, in which the development of the bone in the lesion area stops at the stage of immature braided bone, with the inability to form a normal bone trabecula, resulting in structural changes and reduced mechanical strength of the bone. Repeated pathological fractures often occur with weight bearing, followed by curvature of the affected bone, limb shortening, and abnormal gait. The proximal femur is often involved in FD limb malformations, with complex types and degrees, most of which are manifested as gradually aggravating hip varus and diaphysial curvature. The proximal femur is a common site of limb deformity caused by FD, the types and severity of malformations are complex and varied, which is usually manifested as gradually aggravated varus hip joint and diaphysis bending deformity. The purpose of deformity correction is to restore the normal mechanical axis and length of the femur, thereby restoring the function of the limb, avoiding the progression of deformity and relieving the pain symptoms caused by repeated pathological microfractures, which is more important than the treatment of the lesion itself. The preoperative treatment plan should be made individually for each patient according to the location and extent of the lesion and the type of the lesion. The patients need to be followed up for a long time to adjust the correction plan. Whether the lesion should be curette and bone graft and the type of bone graft material used are still controversial. The femoral deformity of FD should be analyzed based on the principles of deformity correction, the type of deformity and the location of the apex of the deformity should be determined, the osteotomy plan should be designed, and the preoperative simulation should be performed. Both intramedullary and extramedullary fixation after osteotomy can provide sufficient biological stability. The choice of fixation device should be determined according to the specific situation during the operation. There is no obvious abnormality in bone healing and regeneration in FD patients, but dysplastic bone tissue is included in the callus formation. The limb deformity of FD patients is prone to relapse after treatment, long-term close follow-up is needed to adjust the correction plan.

Objective:To explore the status quo of pediatric nurses' cognition of death education, and analyze its influencing factors, so as to provide experience and reference for carrying out death education in pediatric wards.Methods:In this study, 827 nurses from 15 children's hospitals in China were investigated by using the scale for evaluating the cognition of death education in medical staff prepared by Zhang Yan-gai, and the related factors affecting the cognition of death education were analyzed. SPSS 23.0 was used for independent-samples t-test and ANOVA analysis, and multiple regression equation was used to further analyze the relationship between the cognitive factors of death education in pediatric nurses. Results:The total score of death education cognition of pediatric nurses was (35.61±5.64) points, which was lower than the median score of 36 points. The degree of death education cognition of pediatric nurses was at the medium-low level. The results of correlation analysis showed that the professional title of nurses (regression coefficient: 0.064, P=0.045), the training demand for death education (regression coefficient: 0.300, P<0.001), and the way of understanding (regression coefficient: 0.018, P=0.003) were independent influencing factors of the death education cognition level of pediatric nurses. Conclusions:Pediatric nurse death education related theoretical knowledge should be improved through various professional trainings. The hospitals should include death education in pediatric nurse continuing education training plan to improve pediatric nurses' cognitive level of death education through a variety of ways and means, promote the application of death education activities carried out in pediatric ward in the hospice care, reduce deaths impact to nurse their own emotions, and alleviate parents' anxiety and painful experience, thereby improving medical satisfaction.

Transient expression is the major method to express foot-and-mouth disease virus (FMDV) capsid proteins in mammalian cells. To achieve stable expression of FMDV capsid proteins and efficient assembly of virus like particles (VLPs) in cells, the plasmids of piggyBac (PB) transposon-constitutive expression and PB transposon-tetracycline (Tet) inducible expression vectors were constructed. The function of the plasmids was tested by fluorescent proteins. By adding antibiotics, the constitutive cell pools (C-WT, C-L127P) expressing P12A3C (WT/L127P) genes and the inducible cell pools (I-WT, I-L127P) expressing P12A3C (WT/L127P) genes were generated. The genes of green fluorescent protein, 3C protease and reverse tetracycline transactivator (rtTA) were integrated into chromosome, which was confirmed by fluorescence observation and PCR testing. The cell pool I-L127P has a stronger production capacity of capsid proteins and VLPs, which was confirmed by Western blotting and enzyme linked immunosorbent assay (ELISA), respectively. In conclusion, inducing the chromosomal expression of FMDV capsid proteins was firstly reported, which may facilitate the technical process of mammalian production of FMDV VLPs vaccine and the construction of mammalian inducible expression systems for other proteins.

Objective:To evaluate the feasibility of CT volume rendering technology in the assessment of the physeal bar in children.Methods:A retrospective analysis of the relevant CT data of 20 patients with physeal bar from January 2019 to December 2021, 13 boys and 7 girls, age 9.94±2.91 years. The etiology included 17 cases of trauma, 1 cases of tumor, and 2 cases of unknown. The affected sites included 9 cases of distal femur, 5 cases of proximal tibia, 3 cases of distal tibia, and 3 cases of distal radius. Evaluate using volume rendering technology and traditional surface reconstruction technology respectively and the index include the size and type of physeal bar.Results:All the children were successfully examined at one time, and none of them required sedation. The average exposure time was 3.81±0.83 s. During scanning, only low-dose radiation was performed on the affected joints, and routine radiation protection was performed. Using volume rendering technology to evaluate the proportion of the physeal bar, the results obtained by the three testers were 25.36%±15.36%, 24.75%±16.18%, 26.70%±17.72%, and the intraclass correlation coefficient value ( ICC) was 0.976, the three repeated measurements by one tester were 25.36%±15.36%, 25.41%±15.20%, 25.74%±16.00% ( ICC=0.990). Compared with the traditional curved planar reconstruction technical evaluation, the results obtained by the three testers were 28.36%±16.74%, 23.66%±19.87%, 35.25%±15.92% ( ICC=0.737), the three repeated measurement results by one tester were 28.36%±16.74%, 31.66%±13.06%, 30.89%±12.52% ( ICC=0.875). The volume rendering technology was better than the curved planar reconstruction technique. Paired t test was performed on the measurement results of three evaluators and the three repeated measurements of the same evaluator, and the differences were statistically significant ( P<0.05). The same results were acquired by using volume rendering technology to evaluate the type of phseal bar with three testers; but there were 18 cases had the same results by using curved planar reconstruction technology and 2 cases had differences, showing the volume rendering technology was more accurate. Conclusion:Low-dose CT scanning volume rendering technology is an effective method to evaluate the physeal bar in children. It can more intuitively and accurately evaluate the proportion and type of the bar while reducing the radiation exposure of children. The consistency with inter-group and intra-group is better than traditional curved planar reconstruction technique with good reproducibility and clinical significance.

OBJECTIVE To investigate the component characteristics and anti-infla mmatory activities of the low polarity parts from Sabia campanulata ，S. discolor and S. parviflora . METHODS Gas chromatography-mass spectrometry was used to analyze the components of low polarity parts eluted by petroleum ether from petroleum ether extract of dried stems and leaves of S. campanulata，S. discolor and S. parviflora . The chromatographic peaks were retrieved by both NIST 17 and Wiley 275 database， and their structures of each compound were compared and identified manually. The relative percentage content of each component was calculated by peak area normalization method. With indomethacin as positive control and the inhibition rate of nitric oxide （NO）production as the index ，the effects of the low polarity parts of the above three species of Sabia genus on the production of NO in lipopolysaccharide-induced human rheumatoid arthritis fibroblast-like synoviocytes （RA-FLS） and mouse mononuclear macrophage RAW 264.7 were compared ；the half inhibitory concentration （IC50）was calculated. RESULTS Totally 70，40 and 33 chemical components were identified respectively from the low polarity parts of S. campanulata ，S. discolor and S. parviflora ， including long-chain fatty hydrocarbons ，long-chain alcohol/aldehyde/ester ，monoterpenes；but there were only 5 common components in the three species ，such as dodecane and docosane，etc. S. campanulata contained abundant terpenoids （40.89％）； the relative percentage content of triterpenoids was high in S. discolor （30.29％）；the relative percentage content of long-chain fatty hydrocarbons was high in S. parviflora （87.70％）. The values of IC 50 of the low polarity parts of the above three species of Sabia genus to the production of NO in RA-FLS cells were 2.22，1.69 and 4.15 μg/mL，respectively. The values of IC 50 of them to the production of NO in RAW 264.7 cells were 1.23，4.02 and 3.05 μg/mL respectively，and all of them were lower than indomethacin （12.97，10.66 μg/mL）. CONCLUSIONS The components of the low polarity parts fr om the above three species of Sabia genus are mainly long-chain fatty hydrocarbons ， monoterpenes and long-chain alcohol/aldehyde/ester ， and all of them have certain anti-inflammatory activities.
