Mucopolysaccharidosis type ⅣA（MPS ⅣA）is an autosomal recessive lysosomal storage disorder caused by deficiency of the N-acetylgalactosamine-6-sulfatase（GALNS）enzyme. This enzymatic defect leads to pathological accumulation of keratan sulfate（KS）and chondroitin-6-sulfate（C6S）within lysosomes，resulting in multisystem organ dysfunction characterized predominantly by progressive skeletal dysplasia. The clinical manifestations of MPS ⅣA demonstrate remarkable heterogeneity，ranging from mild forms to life-threatening severe phenotypes. The current mainstay therapeutic approaches consist of enzyme replacement therapy（ERT）and hematopoietic stem cell transplantation（HSCT）. However，these treatment modalities demonstrate limited efficacy in ameliorating skeletal abnormalities. Recent preclinical studies have shown promising results with novel therapeutic approaches including gene therapy and substrate reduction therapy for improving skeletal lesions. This review systematically summarizes current treatment options and research advances in MPS ⅣA to provide evidence-based guidance for clinical practice and future investigations.

【Objective】 To observe the clinical efficacy of ultrasound-guided autologous platelet- rich plasma (PRP) injection for the treatment of common peroneal nerve compression syndrome, and to provide reference for the treatment of peripheral nerve compression diseases. 【Methods】 A patient with common peroneal nerve compression syndrome was treated with ultrasound-guided injection of autologous PRP for nerve water separation. The efficacy of PRP injection treatment on common peroneal nerve compression syndrome was evaluated by observing the patient′s symptoms, electrophysiological and imaging manifestations. 【Results】 After systematic injection therapy, the patient′s symptoms, signs and electromyography showed significant improvement, and there were no significant adverse reactions after 3 months of follow-up. 【Conclusion】 Ultrasound guided PRP injection therapy improves neurological dysfunction in common peroneal nerve compression syndrome.

Objective To evaluate the value of a machine learning-based biparametric magnetic resonance imaging(bpMRI)radiomics model in predicting clinically significant prostate cancer(csPCa)in the transitional zone.Methods A retrospective analysis was con-ducted on 507 cases in two medical centers.All patients underwent prostate MRI examinations before surgery,with complete patho-logical data.The case distribution was as follows:256 cases of csPCa,97 cases of clinically insignificant prostate cancer(ciPCa),and 154 cases of benign prostatic hyperplasia(BPH).Using the R language,the data from Center One was randomly divided into training and test groups at a ratio of 7∶3,and the data from Center Two as an independent external validation group.The image features from T2 WI and diffusion weighted imaging(DWI)were extracted,and the least absolute shrinkage and selection operator(LASSO)was used to reduce dimensionality and filter features.Two datasets were constructed based on T2 WI features alone and combined T2 WI and DWI features.Six prediction models were established using random forest(RF),logistic regression(LR),and support vector machine(SVM).The efficacy of six models of T2 WI features and combined T2 WI and DWI features in the diagnosis of prostate dis-eases through receiver operating characteristic(ROC)curve,area under the curve(AUC),and decision curve analysis(DCA)were compared and evaluated.Results In the training group,feature screening identified 7 and 8 features from the T2WI single sequence and the T2WI with DWI dual sequence for csPCa prediction in the transitional zone.The results showed that the T2WI with DWI dual sequence RF model had the highest AUC performance.The AUC of the training,test,and validation groups were 0.950,0.866,and 0.818,respectively.The test group accuracy was 0.805,sensitivity was 0.690,and specificity was 0.920;the validation group accu-racy was 0.726,sensitivity was 0.661,and specificity was 0.793.DCA showed that within a wide probability threshold range,the T2 WI with DWI dual sequence RF model had the greatest net benefit.Conclusion Based on the bpMRI radiomics model,non-invasive prediction of csPCa in the transitional zone can be achieved before surgery,which helps to make clinical diagnosis and treatment decisions.

AIM: To observe the clinical efficacy of multi -glycoside of tripterygium wilfordii (GTW) on diabetic nephropathy. METHODS: Fifty-one patients with diabetic kidney disease (DKD) with a history of GTW dosing admitted to the outpatient clinic of Yijishan Hospital affiliated to Wannan Medical College from June 2019 to October 2022 were selected as study subjects, and were followed up regularly to observe the changes in laboratory indexes before and after GTW dosing and adverse drug reactions after 6 months of treatment. The t-test, Mann-Whitney U-test or χ

Objective To evaluate the performance of MRI in predicting pathological response of different breast cancer subtypes after neoadjuvant chemotherapy(NAC).Methods The MRI images and postoperative pathological results of 91 patients with breast cancer after NAC were analyzed retrospectively.The correlation between the imaging features of different molecular subtypes of breast cancer and postoperative pathological results was studied,and the diagnostic performance of MRI in predicting pathological response after NAC was evaluated,with postoperative pathological results referred as the diagnostic standard.Results Of 91 patients,27(29.7％)and 35(38.5％)cases were diagnosed as imaging complete response(iCR)and pathological complete response(pCR),respectively.The accuracy of MRI in predicting pathological response after NAC was 84.62％,with 94.64％sensitivity,68.57％specificity,and positive predictive value(PPV)and negative predictive value(NPV)of 82.81％and 88.89％,respectively.Conclusion MRI can accurately predict the pathological response of the human epidermal growth factor receptor-2(HER-2)+and triple-negative breast cancer after NAC.

Objective:To investigate the clinical value of zoledronic acid in improving the prognosis of osteoporotic hip fracture and preventing its sequential contralateral hip fracture.Methods:A retrospective study of 206 patients diagnosed with hip fragile fractures in China Medical University Affiliated Shengjing Hospital and treated with anti-osteoporotic drugs after surgery was conducted. The prognosis of patients with hip fracture using survival rate analysis and the risk factors of acute febrile complications with multivariate analysis after zoledronic acid treatment were evaluated. Furthermore, chi-square test and multivariate analysis was used to explore whether zoledronic acid decreases the occurrence of the contralateral sequential fracture.Results:The 3-year survival rate of patients with overall hip fracture was higher in zoledronic acid treatment group compared with control group( P=0.026), with the incidence of fever at 53.3%. The age [ OR=0.786, P=0.027, the area under receiver operating characteristic (ROC) curve was 0.724] and cardiopulmonary complications ( OR=0.043, P=0.025, the area under ROC curve was 0.628) were significantly correlated with the occurrence of acute febrile response. The incidence of sequential contralateral fractures in zoledronic acid treatment group was significantly lower than that in control group ( χ2=4.356, P=0.037). The application of zoledronic acid ( OR=0.160, P=0.007, the area under ROC curve is 0.586) and the type of femoral neck fracture ( OR=0.196, P=0.001, the area under ROC curve is 0.607) were statistically associated with the occurrence of sequential fractures. Conclusion:Zoledronic acid treatment improves the outcome of patients with osteoporotic hip fracture and reduces the incidence of sequential hip fractures, especially femoral neck fracture. Senile age and cardiopulmonary complications might be associated with lower risk of acute febrile reactions after zoledronic acid treatment.
