Hepatolenticular degeneration， also known as Wilson disease （WD）， is a hereditary disease caused by mutations in the ATP7B gene， leading to copper metabolism disorders. Gene mutations result in impaired synthesis of copper-binding protein， and abnormal excretion of copper through bile leads to pathological deposition of copper in various organs， ultimately causing multi-organ damage. The insidious onset and low specificity of symptoms make it difficult to diagnose this disease. On the basis of existing studies and the theory of latent toxin， this paper proposes that latent toxin in kidney collaterals is the main pathogenesis of renal injury in WD. It is pointed out that health Qi deficiency and latent pathogen are the premises for the occurrence of this disease， and the transformation of latent pathogen into toxin is the ley pathological process. Toxin damaging kidney collaterals is the ultimate result. According to the pathogenesis， this paper proposes the treatment principle of reinforcing healthy Qi and resolving toxin and treatment based on syndrome differentiation. This review provides new ideas for the diagnosis and treatment of renal injury in WD with traditional Chinese medicine.

ObjectiveTo observe the clinical efficacy of Gandouling decoction combined with neuromuscular electrical stimulation （NMES） in the treatment of dysphagia in Wilson disease （WD） with combined phlegm and stasis. MethodsA total of 80 WD patients with dysphagia due to combined phlegm and stasis treated in the Department of Encephalopathy， the First Affiliated Hospital of Anhui University of Chinese Medicine were randomized into a control group and an observation group， with 40 patients in each group. In addition， 40 healthy volunteers were recruited as the normal group. The control group was treated with basic copper drainage combined with NMES. The observation group was treated with Gandouling Decoction on the basis of the therapy in the control group. Each course of treatment lasted for 8 days， and the patients were treated for a total of 4 courses. All subjects underwent video fluoroscopic swallowing study （VFSS） before and after treatment. During the examination， contrast agents with 4 different characters were used for the swallowing action， and the passing time was recorded. The TCM syndrome score， water swallow test score， standard swallowing assessment （SSA） score， and 24-h urinary copper level before and after treatment were analyzed. ResultsWhen performing VFSS， the passing time of contrast agents of different characters in the oral stage was longer in the WD group than in the normal group （P<0.01）， while it had no significant difference in the pharyngeal stage. After treatment， the passing time in the oral stage shortened in the control and observation groups （P<0.01）， and the observation group outperformed the control group （P<0.01）. After treatment， both the control and observation groups showed declines in TCM syndrome score and SSA score （P<0.01） and an increase in water swallow test score （P<0.01）， and the changes were more obvious in the observation group than in the control group （P<0.01）. In addition， the treatment in the control and observation groups elevated the 24-h urinary copper level （P<0.01）， and the elevation in the observation group was more obvious than that in the control group （P<0.01）. Neither group showed obvious adverse reaction. ConclusionGandouling decoction combined with NMES can significantly ameliorate dysphagia in WD patients with the syndrome of combined phlegm and stasis regarding the TCM syndrome score， water swallow test score， and SSA score， demonstrating definite clinical efficacy and high safety.

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.

Nichrome(NiCr)wire with strong mechanical properties,excellent flexibility,good corrosion resistance and high thermal stability was selected as a promising fiber substrate to replace the fragile fused-silica counterpart.The NiCr layered double hydroxide nanosheets(NiCr LDHs NSs)were in-situ grown on the NiCr fiber substrate.Then,the extraction performance of the NiCr@NiCr LDHs NSs fiber was evaluated using four kinds of chlorophenol(CPs)as model compounds combined with high performance liquid chromatography-ultraviolet detection(HPLC-UV).The results showed that the assembled fibers exhibited superior extraction selectivity and enhanced extraction efficiency for CPs in comparison to commercial PA,PDMS,and PDMS/DVB fibers.Under the optimized experimental conditions,the established method showed good linearity in the range of 0.2-200 μg/L,with coefficient of determination(R2)>0.9989.The limits of detection(LODs)and limits of quantification(LOQs)were 0.050-0.157 μg/L and 0.165-0.502 μg/L,respectively.Relative standard deviations(RSDs)for intra-day and inter-day analyses ranged from 2.85%to 4.05%and from 3.16%to 4.96%,respectively.The developed method with the constructed fiber was applied to preconcentration and detection of different types of CPs in real water samples,showing satisfactory recoveries ranging from 80.0%to 106.9%,with RSDs of 3.12%-7.81%.Moreover,the NiCr@NiCr LDHs NSs fiber could maintain good extraction performance even after 240 extraction-desorption cycles.

Objective To evaluate the safety,efficacy,and long-term outcomes of transoral ro-botic surgery(TORS)for the resection of parapharyngeal space tumors(PPST).Methods A retro-spective analysis was conducted on clinical data from 16 patients who underwent TORS for PPST re-section.Surgical outcomes,postoperative pathological findings,and complication rates were ob-served.Follow-up evaluations were performed to assess patient satisfaction,swallowing function re-covery,and tumor recurrence.Results Except for one patient who required an additional neck inci-sion,the remaining 15 patients successfully completed the surgery via the oral route.None of the pa-tients underwent tracheotomy or mandibulotomy.The mean surgical duration was 43.9 minutes,with an average tumor diameter of 4.5 cm resected.The mean intraoperative blood loss was 35.3 mL.Patients resumed oral intake after an average of 3.8 days and had a mean postoperative hospital stay of 8.3 days.Postoperative pathological examination revealed that the most common tumor type was pleomorphic adenoma(56.2％,9/16),followed by schwannoma(25.0％,4/16),with one case of basal cell adenoma,cyst,and lipoma,respectively.One patient experienced transient Horner's syndrome,two had wound dehiscence that healed spontaneously,and one had spontaneous wound healing after drainage tube dislodgement.With a mean follow-up of 79.5 months,no tumor recurrence or severe complications were observed.All patients had good swallowing function and were satisfied with the surgical outcomes.Conclusion TORS for PPST resection offers advantages such as clear surgical visualization,direct surgical access,minimal blood loss,reduced trauma,favorable cosmetic re-sults,and rapid postoperative recovery.It also demonstrates good long-term outcomes,with high safety and efficacy.

Objective To investigate the mechanism of inducing macrophage polarization induced by acupoint effect of electroacupuncture to promote the repair of acute skeletal muscle injury.Methods 45 SD rats were randomly divided into blank group,model group,electroacupuncture group(EA group),sodium chrominate group (DSCG group) and electroacupuncture+sodium chrominate group (hereinafter referred to as EA+DSCG group),with 9 rats in each group. The rats in the EA group and the EA+DSCG group were subjected to EA intervention at the right "Chengshan" (BL57) and "Yanglingquan"(GB34),with a frequency of 2 Hz/100 Hz. The gait changes of rats were recorded by animal gait analyzer. The morphological changes of the right gastrocnemius were observed by HE staining. The changes of mast cell aggregation and degranulation in local skin muscles of "chengshan" point were observed by toluidine blue staining. The expressions of Pax7,MyoD and skin mast cells and 5-HT in the right gastrocnemius were detected by immunofluorescence method. The positive expressions of CD68 and CD206 in right gastrocnemius macrophage was observed by immunohistochemical staining.Results Compared with blank group,the wiggle time of the right hind leg in model group and DSCG group increased,stride length decreased,HE staining showed inflammatory cell infiltration,myocyte enlargement,degeneration and necrosis. The degranulation rate of local skin mast cells in "Chengshan" (BL57) area increased,and the expressions of mast cell tryptase,5-HT,Pax7,MyoD,CD68 and CD206 increased (P<0.05). Compared with model group,the wiggle time of the right hind leg in EA group and EA+DSCG group decreased,stride length increased,HE staining showed that inflammatory cell infiltration was reduced,muscle cells were uniform in size and arranged neatly. Mast cell degranulation rate increased significantly in EA group,and the expressions of mast cell tryptase,5-HT,Pax7,MyoD and CD206 increased (P<0.05),while CD68 expression decreased (P<0.05). Compared with EA+DSCG group,the degranulation rate of mast cells and the expressions of mast cell tryptase,5-HT,Pax7,MyoD and CD206 increased (P<0.05),while CD68 expression decreased in EA group (P<0.05). Conclusion EA "Chengshan" (BL57) and "Yanglingquan" (GB34) can stimulate acupuncture points to locally induce mast cell degranulation,promote the polarization of macrophages,and then activate muscle satellite cells to play the regulatory process of repairing skeletal muscle injury.

Excavating the quantitative trait locus (QTL) associated with rice cooking quality, analyzing candidate genes, and improving cooking quality-associated traits of rice varieties by genetic breeding can effectively improve the taste of rice. In this study, we used the indica rice HZ, the japonica rice Nekken2 and 120 recombinant inbred lines (RILs) populations constructed from them as experimental materials to measure the gelatinization temperature (GT), gel consistency (GC) and amylose content (AC) of rice at the maturity stage. We combined the high-density genetic map for QTL mapping. A total of 26 QTLs associated with rice cooking quality (1 QTL associated with GT, 13 QTLs associated with GC, and 12 QTLs associated with AC) were detected, among which the highest likelihood of odd (LOD) value reached 30.24. The expression levels of candidate genes in the localization interval were analyzed by quantitative real-time polymerase chain reaction (qRT-PCR), and it was found that the expression levels of six genes were significantly different from that in parents. It was speculated that the high expression of LOC_Os04g20270 and LOC_Os11g40100 may greatly increase the GC of rice, while the high expression of LOC_Os01g04920 and LOC_Os02g17500 and the low expression of LOC_Os03g02650 and LOC_Os05g25840 may reduce the AC. The results lay a molecular foundation for the cultivation of new high-quality rice varieties, and provide important genetic resources for revealing the molecular regulation mechanism of rice cooking quality.

AIM:To investigate the mechanism of Piezo1 channel activation promoting the increase in intra-cellular Ca2+ concentration([Ca2+]i)of rat coronary artery smooth muscle cells(CASMCs).METHODS:The primary CASMCs of SD rats were cultured,and the expression and subcellular localization of Piezo1 in the cells were observed by immunofluorescence staining.The Piezo1 and stromal interaction molecule 1(STIM1)in CASMCs were knocked down by siRNA transfection,and the expression levels of the proteins were detected by Western blot.Utilizing laser confocal mi-croscopy,the change of[Ca2+]i in CASMCs was detected by Fluo-4 AM fluorescent probes.RESULTS:It was confirmed by immunofluorescence staining that the expression of Piezo1 existed in primary rat CASMCs.Immunofluorescence staining also showed that Piezo1 was co-located with sarco-/endoplasmic reticulum Ca2+-ATPase 2(SERCA2),mitochondrial outer membrane protein TOM20 and nuclear membrane protein lamin B1.Western blot results showed that the protein expres-sion levels of STIM1 and Piezo1 were significantly down-regulated by siRNA transfection(P<0.05).Compared with con-trol group,Yoda1,the agonist of Piezo1,could increase the extracellular Ca2+ influx of CASMCs(P<0.01).However,the Ca2+ influx mediated by Yoda1 was not affected by the inhibition of L-type calcium channels.Treatment with Yoda1 in-creased the intracellular Ca2+ release of CASMCs(P<0.01).However,inhibition of calcium channels on endoplasmic re-ticulum,ryanodine receptor and inositol 1,4,5-triphosphate receptor,did not affect intracellular Ca2+ release mediated by Yoda1.After the Ca2+ in endoplasmic reticulum was emptied using thapsigargin(TG),Yoda1 also mediated the Ca2+ re-lease of other organelles in CASMCs(P<0.01).After inhibition of L-type calcium channels,treatment with store-operated calcium channel(SOCC)inhibitor BTP2 or knockdown of STIM1 led to the decrease in extracellular Ca2+ influx of CASMCs mediated by Yoda1(P<0.01).Treatment with TG increased the release of Ca2+ from the endoplasmic reticulum of CASMCs after knockdown of Piezo1(P<0.05),but the extracellular Ca2+ influx mediated by TG was not affected.After inhibition of L-type calcium channels and SOCC,knockdown of Piezo1 led to the decreases in intracellular Ca2+ release and extracellular Ca2+ influx induced by Yoda1(P<0.01).CONCLUSION:The Piezo1 agonist orchestrates the influx of extracellular Ca2+ by activating Piezo1 channels on the cell membrane and inducing the indirect activation of SOCC.More-over,it facilitates the release of Ca2+ from organelles.Consequently,these pathways synergistically elevate the[Ca2+]i of rat CASMCs.
