MethodsA total of 70 patients with WD-related liver fibrosis of liver-kidney deficiency and phlegm-blood stasis syndrome meeting the inclusion criteria were enrolled from Anhui Provincial Hospital of TCM from October 1， 2023， to October 1， 2024. Participants were divided into a control group and an observation group， with 35 cases in each group. The control group received conventional copper chelation therapy with sodium dimercaptopropanesulfonate （DMPS）. On this basis， the observation group was additionally administered GDFMD orally. Each treatment course lasted eight days， for a total of four treatment courses. Efficacy evaluations were performed before treatment and after the second and fourth treatment courses， respectively.

Wilson disease （WD） is an autosomal recessive disorder of copper metabolism， and decoppering therapy and symptomatic treatment are the main Western medicine therapies for WD. This article systematically reviews the understanding of the etiology and pathogenesis of WD in traditional Chinese medicine （TCM） and points out that abnormal natural endowment is the core etiology and pathogenesis of WD， with internal accumulation of copper toxicity as the manifestation， liver/spleen/kidney dysfunction as the root cause， and intermingled “toxin， stasis， phlegm， and deficiency” as the key pathogenesis. Literature research and clinical observation are conducted to summarize the common TCM syndromes of WD， including stagnation of liver Qi， internal retention of damp-heat， phlegm-stasis-heat accumulation syndrome， liver-kidney Yin deficiency syndrome， spleen-kidney Yang deficiency， and syndrome of deficiency damage and phlegm stasis. This article proposes the corresponding therapies and representative prescriptions for each syndrome and discusses the advantages of treatment by stage and integrated traditional Chinese and Western medicine therapy. This article aims to provide a systematic reference for the syndrome differentiation-based treatment of WD in clinical practice of TCM， thereby giving full play to the advantages of TCM in the treatment of this disease.

ObjectiveTo analyze the influencing factors of hepatic fibrosis in patients with Wilson's disease （WD） and to develop and validate a predictive model for hepatic fibrosis in WD that integrates traditional Chinese medicine （TCM） syndromes and modern biomarkers， thus providing a basis for early identification of high-risk populations and medical intervention. MethodsThe clinical data of 220 WD patients diagnosed in the Department of Encephalopathy， The First Affiliated Hospital of Anhui University of Chinese Medicine between January 2010 and December 2024 were retrospectively collected. Through a random number table， patients were assigned into a training set （154 patients） and a validation set （66 patients） in a 7∶3 ratio. Univariate COX regression， LASSO regression analysis， and multivariate COX regression analysis were performed to identify independent influencing factors for hepatic fibrosis in WD patients， and a clinical prediction model was established based on these factors. The discrimination， calibration， and clinical utility of the model were evaluated based on the area under the receiver operating characteristic curve （AUC）， calibration curves， and decision curve analysis （DCA）， respectively. ResultsA total of 220 patients were included. The syndrome of combined phlegm and stasis， triglycerides （TG）， laminin （LN）， and male gender were identified as independent risk factors for hepatic fibrosis in WD patients， while TCM intervention and high-density lipoprotein cholesterol （HDL-C） were protective factors. The C-index indicated excellent discriminative ability （training set： 3-year AUC=0.908， 5-year AUC=0.869， 7-year AUC=0.829； validation set： 3-year AUC= 0.898， 5-year AUC=0.780， 7-year AUC=0.743）. Calibration curves showed good consistency. DCA demonstrated the clinical net benefit probabilities across different risk thresholds at various time points. ConclusionThe predictive model established in this study has high accuracy and can be conveniently used for the early identification and risk prediction of hepatic fibrosis in patients with WD.

Objective To explore the disinfection effect of periodic hypochlorous acid infusion on water supply pipelines.Methods Water specimens from 6 water outlets of central sterile supply department were collected at baseline for microbial culture.After introducing a slightly acidic hypochlorous acid water generator,water speci-mens were collected every 10 days.Continuous disinfection with hypochlorous acid was carried out on the 1st-3rd day,and discontinued on the 4th-10th day.Water specimens of 6 water outlets were collected on the 1st,4th,7th,and 10th day of each cycle,in total 3 cycles.Microbial culture and metagenomic next-generation sequencing(mNGS)analysis were conducted simultaneously on all water specimens from the outlets of the endoscope cleaning tank.Results Before disinfection of the pipeline,a total of 18 bottles of water specimens were collected.Bacterial count of water specimens from 10 bottles(55.56％)was between 102 and 104 CFU/mL,mainly Sphingomonas ad-hesins and Bacillus cereus.After disinfection,only 2 out of 72 water specimens(2.78％)exceeded the bacterial lim-it.The mNGS results showed that three most dominant bacterial genera in the pre-disinfection water specimens were Sphingomonas,Methylobacterium,and Ralstonia,with stringent mapped reads number(SMRN)ranging from 10 000 to 100 000;while the most dominant bacterial genera in post-disinfection water specimens were Lacto-baci-llus,Ralstonia,Acinetobacter,and Bradyrhizobium.PCoA analysis showed that there was a statistically sig-nificant difference in β-diversity of water specimens before and after disinfection(P＜0.05).Conclusion Periodic hypochlorous acid infusion disinfection can effectively remove bacterial biofilms in water pipelines,but there is a risk of bacterial biofilm recovery during disinfection suspension.In the future,monitoring and management of medical water should be strengthened.

OBJECTIVE To observe the clinical efficacy of Gandou Fumu Decoction(GDFMD)combined with swallowing func-tion training on Wilson's disease with dysphagia of phlegm stasis type.METHODS Sixty-eight WD patients in The First Affiliated Hospital of Anhui University of Chinese Medicine were randomly equally divided into a control group(34 cases)and a treatment group(34 cases)during October 2021 to October 2024.Control group patients were treated with basic therapy such as copper drainage and swallowing training,while patients in the treatment group received additional GDFMD.The scores of traditional Chinese medicine(TCM)syndrome scores,Water Swallow Test(WST),Standardized Swallowing Assessment(SSA),Functional Oral Intake Scale(FOIS),Barthel Scale were observed before and after the treatment.24-hour urinary copper,superoxide dismutase(SOD)and malon-dialdehyde(MDA)levels were measured in both groups.RESULTS After treatment,the TCM syndrome scores,SSA,WST scale scores and blood MDA levels of the two groups of patients were significantly reduced(P<0.05,P<0.01),and the treatment group was better than the control group(P<0.05);FOIS,Barthel scale scores,24-hour urine copper content and serum SOD level in both groups were significantly increased(P<0.05,P<0.01),and the treatment group was better than the control group(P<0.05).CON-CLUSION The combined therapy of Gandou Fumu Decoction with swallowing training can improve the swallowing function on Wil-son's disease with dysphagia of phlegm stasis type and enhance the copper removing.The mechanism may be related to improving the level of antioxidant stress.
