Objective:To investigate the efficacy of recombinant human interferon α-2b spray, administered under medication guidance, in the clinical treatment of herpangina.Methods:A total of 76 children with herpangina who were treated at The First People's Hospital of Yongkang between October 2020 and October 2022 were included in this study. Using the random number table method, these patients were randomly assigned to an observation group ( n = 42) and a control group ( n = 34). The control group received conventional treatment, whereas the observation group was administered recombinant human interferon α-2b spray under medication guidance. A comparative analysis was conducted between the two groups, evaluating clinical efficacy, inflammatory factor levels, treatment compliance, and the negative conversion rate of throat swab virology. Results:After treatment, the overall response rate of the observation group [95.24% (40/42)] and treatment compliance [97.62% (41/42)] were significantly higher than those of the control group [76.47% (26/34), 79.41% (27/34), χ2 = 4.27, 4.82, P = 0.040, 0.030]. The levels of C-reactive protein [(6.28 ± 1.64) mg/L], white blood cell count [(6.11 ± 1.10) × 10 9], and serum amyloid A [(3.47 ± 0.89) mg/L] in the observation group were significantly lower than those in the control group [(7.51 ± 1.16) mg/L, (7.51 ± 1.16) × 10 9, (7.82 ± 1.30) mg/L, t = 3.69, 6.46, 17.27, all P < 0.001]. The positive conversion rate of throat swab virology in the observation group [4.76% (2/42)] was lower than that in the control group [26.47% (9/34), χ2 = 5.51, P = 0.190]. Conclusion:The use of recombinant human interferon α-2b spray under medication guidance in the treatment of herpangina can improve treatment compliance, rapidly alleviate clinical symptoms, and significantly improve the prognosis.

Objective:To explore the combination of high risk screening and family screening for potential patients with Fabry disease in adult hemodialysis population, and to improve the diagnostic efficiency of the disease.Methods:It was a cross-sectional investigation study. High-risk screening for Fabry disease was performed on adult hemodialysis patients with end-stage kidney disease who were admitted to Yongkang First People's Hospital of Zhejiang Province between November 2022 and February 2023. Dry blood paper α-galactosidase A (α-Gal A) detection assay was performed in males, or glycosphingolipids (Lyso-GL-3) detection assay was performed in females. GLA genetic assay was performed for further diagnosis after abnormal screening results. Family screening was carried out on the family members of the confirmed Fabry disease patients, and α-Gal A activity and Lyso-GL-3 of peripheral blood were measured. Additionally, urine routine, blood biochemistry, eye examination, hearing test, cranial magnetic resonance imaging, and electrocardiogram were performed to assess organ damage. Results:Among 244 hemodialysis patients, 139 (56.97%) were males and 105 (43.03%) were females. The age ranged from 25 to 81 years (with median age of 61 years). One female patient with Fabry disease was identified GLA IVS4+919G>A mutation, resulting in a total prevalence of 0.41%. Pedigree screening was conducted on 41 family members of the patient, leading to the confirmation of 12 patients (including the proband), including 3 males and 9 females. Among them, 9 patients were abnormal in enzyme examination, 10 patients were abnormal in substrate, and 11 patients were abnormal in gene sequencing. None of the 12 patients exhibited limb pain, hypohidrosis, angiokeratoma, corneal opacity, and hearing impairment. Eight patients had heart abnormalities. Nine patients had abnormal urine routine (albuminuria or hematuria) and one patient had abnormal renal function. Four patients had abnormal cranial magnetic resonance imaging findings. Conclusions:One GLA IVS4+919G>A mutation family is successfully identified through the combination of high-risk screening and family screening in adult hemodialysis patients, with a total of 12 cases of Fabry disease. The combination of high-risk screening and family screening proves to be effective in detecting potential patients with Fabry disease, and improve the screening efficiency of Fabry disease.
