Objective:To analyze the efficacy of enzyme replacement therapy and anti-drug antibody production in children with Fabry disease.Methods:The clinical data of 7 children with Fabry disease treated with enzyme replacement therapy for more than 1 year at Children′s Hospital of Zhejiang University School of Medicine from July 2021 to June 2024 were retrospectively analyzed. The basic information and the changes of related clinical indicators before and after treatment were collected. Paired sample t test was used to compare renal function, left heart mass index, pain score and other related indexes before and after treatment. The anti-drug antibodies were detected by enzyme-linked immunosorbent assay. Results:A total of 6 boys and 1 girl were included. The age of diagnosis was (12.2±1.8) years. After 1 year of enzyme replacement therapy, the abnormal substrate globotriaosylsphingosine and brief pain inventory scores of all children were significantly lower than those before treatment ((16±11) vs. (63±42) μg/L, 22±19 vs. 45±29, t=3.88, 3.43, both P<0.05). There were no significant differences in glomerular filtration rate, urinary microalbumin to creatinine and left heart mass index before and after treatment ((124±35) vs. (136±26) ml/(min·1.73 m 2), (9.3±8.3) vs. (3.8±2.5) mg/g, (38±9) vs. (33±6) g/m 2.7, t=1.33, 1.74, 1.19, all P>0.05). Patients 4, 5 and 6 developed anti-drug antibodies at 1 month, 4 months and 1 month after medication, respectively. Patient 4 had persistently high anti-drug antibody titers (absorbance 3.65-3.73) accompanied by urticaria, elevated globotriaosylsphingosine and worsening clinical symptoms. Conclusions:The enzyme replacement therapy can effectively improve the clinical symptoms and reduce the level of globotriaosylsphingosine in children with Fabry disease. The anti-drug antibody is common in patients after long-term enzyme replacement therapy and may diminish the efficacy, which needs dynamic monitoring.

Aromatherapy refers to the method of using the aromatic components of plants in appropriate forms to act on the entire body or a specific area to prevent and treat diseases. Essential oils used in aromatherapy are hydrophobic liquids containing volatile aromatic molecules， such as limonene， linalool， linalool acetate， geraniol， and citronellol. These chemicals have been extensively studied and shown to have a variety of functions， including reducing anxiety， relieving depression， promoting sleep， and providing pain relief. Terpenoids are a class of organic molecules with relatively low lipid solubility. After being inhaled， they can pass through the nasal mucosa for transfer or penetrate the skin and enter the bloodstream upon local application. Some of these substances also have the ability to cross the blood-brain barrier， thereby exerting effects on the central nervous system. Currently， the academic community generally agrees that products such as essential oils and aromatherapy from aromatic plants have certain health benefits. However， the process of extracting a single component from it and successfully developing it into a drug still faces many challenges. Its safety and efficacy still need to be further verified through more rigorous and systematic experiments. This article systematically elaborated on the efficacy of aromatic substances， including plant extracts and natural small molecule compounds， in antibacterial and antiviral fields and the regulation of nervous system activity. As a result， a deeper understanding of aromatherapy was achieved. At the same time， the potential of these aromatic substances for drug development was thoroughly explored， providing important references and insights for possible future drug research and application.

ObjectiveTo investigate the protective effect of salidroside against nonalcoholic fatty liver disease （NAFLD） and its mechanism of action. MethodsA total of 24 male KM mice were randomly divided into normal group， HFD group， HFD+blank control group， and HFD+salidroside group， with 6 mice in each group. The mice in the normal group were given normal diet， and those in the other groups were given high-fat diet. After 14 weeks of modeling， the mice were given salidroside 100 mg/kg/day by gavage， and related samples were collected at the end of week 22. Enzyme-linked immunosorbent assay was used to measure the serum levels of related biochemical parameters including alanine aminotransferase （ALT）， aspartate aminotransferase （AST）， triglyceride （TG）， total cholesterol （TC）， high-density lipoprotein cholesterol （HDL-C）， and low-density lipoprotein cholesterol （LDL-C）； HE staining and NAFLD activity score （NAS） were used to observe the liver histopathology of mice； Western blot was used to measure the changes in the expression of NAMPT， Sirt1， AMPKα， and SREBP1 in liver tissue. A one-way analysis of variance was used for comparison between multiple groups， and the least significant difference t-test was used for further comparison between two groups. ResultsCompared with the normal group， the HFD group had obvious steatosis and extensive large lipid droplets in liver tissue， with significant increases in NAS score （P<0.01） and the content of AST， ALT， TG， TC， and LDL-C in peripheral blood （all P<0.05） and a significant reduction in the content of HDL-C （P<0.05）， as well as significant reductions in the expression levels of NAMPT， AMPKα， and Sirt1 in liver tissue （all P<0.05） and a significant increase in the expression level of SERBP1 （P<0.01）. Compared with the HFD group and the HFD+blank control group， the HFD+salidroside group had reductions in the distribution of vacuolar lipid droplets and intralobular inflammation in liver tissue， alleviation of the ballooning degeneration of hepatocytes， significant reductions in NAS score （P<0.01） and the content of AST， ALT， TG， and LDL-C in peripheral blood （all P<0.05）， and a significant increase in the content of HDL-C （P<0.05）， as well as significant increases in the expression levels of NAMPT， AMPKα， and Sirt1 in liver tissue （all P<0.05） and a significant reduction in the expression level of SERBP1 （P<0.01）. ConclusionSalidroside can significantly improve the pathological state of mice with NAFLD induced by high-fat diet and exert a protective effect against NAFLD by increasing the expression of NAMPT， Sirt1， and AMPKα and reducing the expression of SERBP1.

Purpose To investigate the diagnostic value of 18F-FDOPA PET/CT imaging and semi-quantitative analysis platform for the diagnosis of Parkinson's disease(PD).Materials and Methods There were 27 healthy controls and 56 clinically diagnosed PD patients,including 33 early PD(Hoehn-Yahr class Ⅰ-Ⅱ)and 23 advanced PD(Hoehn-Yahr class Ⅲ-Ⅳ),underwent 18F-FDOPA PET imaging in Nanjing First Hospital,Nanjing Medical University were consecutively enrolled from January 2018 to December 2019.The striatal to occipital ratio(SORs)in radioactivity was calculated by HERMES BRASS platform,thereby completing the semi-quantitative analysis of the brain based on regions of interest and observing the asymmetry of the striatal subregions in early-stage PD and late-stage PD patients.Using artificial intelligence techniques to perform principal component analysis on the SORs of the striatal subregions in PD group and healthy control group,the degree of data aggregation and the distinguishability between groups were observed.Results The SORs was significantly reduced in the whole caudate,anterior,posterior putamen and striatum of advanced PD patients(t=9.02-11.72,P<0.000 1).The area under the curve was 0.952,0.973,0.995 and 0.982,respectively.Compared with the healthy control group,the loss of striatal asymmetry index(mean)in each subregion of the striatum in early PD group was caudate(7.61±5.50)%,anterior putamen(11.43±8.97)%,posterior putamen(17.17±11.63)%,and whole striatum(10.65±7.46)%,respectively.The uptake of 18F-FDOPA in the striatum of PD patients was significantly reduced,and the most obvious loss of early PD patients was contralateral posterior putamen,with a decrease of 34%.Conclusion The platform semi-quantitative analysis of 18F-FDOPA PET/CT images provides objective semi-quantitative values for early diagnosis and differential diagnosis of PD.Asymmetry in the striatum,especially in the putamen,may be an important parameter for early diagnosis of PD..

Objective:To construct an evaluation system for clinical thinking ability of general practitioners in the treatment of multimorbidity.Methods:This was a cross-sectional study. The draft of evaluation indexes for clinical thinking ability of general practitioners in treatment of multimorbidity was preliminary developed through literature review, collation, analysis and discussion. Nineteen clinical and teaching experts of general practice were selected for consultation via anonymous convenient sampling. From January to June 2022, 2 rounds of expert consultation were conducted using the Delphi method. During the first round of consultation, according to the survey feedback, we modified and improved the evaluation system of general practitioners′ clinical thinking ability for multi-disease co-treatment. During the second round, experts were asked to assess the importance of each index, and to calculate the weight of each index accordingly. Questionnaires were sent to experts via letters. The content of the questionnaires encompasses the basic information of experts, evaluation for various indexes and relevant opinions. The mean value of importance assignment ≥3.5, coefficient of variation ≤0.25 and the full score frequency ≥30% were taken as the criteria. Indexes unsatisfying the criteria were removed, so that the final index system could be constructed.Results:The average age of 19 experts was 50.2 years old, 9 of them were male. A total of 2 rounds of expert consultation were conducted, 19 questionnaires were issued in each round, and 19 effective questionnaires were received afterwards. In the first round of consultation, 10 experts put forward revised opinions, and some indexes were adjusted according to the definition criteria and the discussion of the research group. In the second round of consultation, 3 experts put forward suggestions for modification. According to the definition criteria, no need to delete the indexes. After discussion by the research group, some indexes were adjusted, and finally an evaluation system of clinical thinking ability for multi-disease co-treatment of general practitioners was established, including 4 first-level indexes and 30 second-level indexes. The weights of the 4 first-level indexes in descending order were "overall thinking ability" (38.01%), "diagnostic thinking ability" (33.96%), "evidence-based thinking ability" (14.75%), and "critical thinking ability" (13.28%). Among the 30 secondary indexes, the top 5 were "ability to identify and handle priority emergency incidents" (5.04%), "risk assessment and critical illness identification ability" (4.63%), "emergency referral ability" (4.61%), "communication and expression ability" (4.57%), and "standardized diagnosis and treatment ability" (4.23%).Conclusion:This study successfully constructed an evaluation system for clinical thinking ability of general practitioners in the treatment of multimorbidity.

BACKGROUND:Wnt signaling pathway is overexpressed in degenerative intervertebral discs,and inhibition of its expression can delay the process of intervertebral disc degeneration.Therefore,Wnt signaling pathway is closely related to intervertebral disc degeneration. OBJECTIVE:To summarize the relationship between Wnt signaling pathway and intervertebral disc,especially the specific role and influence of Wnt signaling pathway in intervertebral disc degeneration. METHODS:The first author took"intervertebral disc,Wnt,cell proliferation,cell senescence,cell apoptosis,extracellular matrix"as the English search terms.PubMed,Web of science and OVID LWWSpringerlink were searched for articles published from 2000 to January 2023,and articles related to Wnt signaling pathway and disc degeneration were consulted.Totally 54 articles were reviewed by reading,collating and preserving. RESULTS AND CONCLUSION:(1)During intervertebral disc formation in embryos,Wnt signaling pathway is overexpressed,which is involved in intervertebral disc formation and promotes posterior extension of notochord.(2)During intervertebral disc degeneration,Wnt signaling pathway can inhibit cell proliferation by stagnating cell cycle,increase the expression of age-related proteins and promote cell aging by participating in oxidative stress,and participate in cell apoptosis by regulation of long non-coding RNA.(3)Wnt signaling pathway can also decrease extracellular matrix related protein synthesis,promote extracellular matrix degradation and accelerate intervertebral disc degeneration.(4)Wnt signaling pathway can promote cell regeneration by activating as early intervertebral disc formation signal and participate in inducing stem cells to differentiate into intervertebral disc cells to repair damaged intervertebral disc.For example,Wnt signaling pathway can induce stem cells from cartilage endplate cells to migrate and transform to intervertebral disc.
