Objective To explore the therapeutic mechanism of maggot for psoriasis-like lesions in mice from the perspective of immune stress and complement activation regulation.Methods Thirty-six male C57BL/6 mice were randomly divided into control group,model group,maggot(1.25%,2.5%,and 5%)groups,and Benvitimod(1%)group.Psoriasis-like lesions were induced by application of imiquimod cream,and the severity of skin lesions was assessed using the modified Psoriasis Area and Severity Index(MPASI)score.Auricular swelling of the mice was observed,and histopathological changes of the skin lesions were examined with HE staining.Scratching behavior of the mice was observed and the spleen index was calculated.Toluidine blue staining was used to detect mast cells in the skin lesions,and serum levels of IgG,IgM,the complements CH50,C1s,C3,C3a,C5 and C5a,and the inflammatory factors IL-23,IL-17A and TNF-α were determined with ELISA.Results In mice with imiquimod-induced psoriasis-like skin lesions,treatment with the maggot at the 3 doses significantly decreased MPASI score,alleviated auricular swelling and pathologies in the skin lesions,reduced scratching behaviors,spleen index,and the number of mast cells in the lesions.Treatment with high-dose maggot significantly lowered serum levels of IgG,C1s,C3a,C5a,IL-23,IL-17A and TNF-α and the levels of C1s,C3,C3a,C5 and C5a in the lesion tissue,and increased serum levels of CH50,C3,and C5.The therapeutic effect of maggot showed a dose-effect dependence.Conclusion Maggot can alleviate psoriasis-like skin lesions in mice by inhibiting immune stress and complement activation.

Ultrasonography 2024;43(4):263-271
Purpose:
This study aimed to evaluate changes in ultrafast pulse wave velocity (ufPWV) in individuals with arterial stiffness and subclinical atherosclerosis (subAS), and to provide cutoff values.
Methods:
This retrospective study recruited 231 participants, including 67 patients with subAS. The pulse wave velocity was measured at the beginning and end of systole (PWV-BS and PWVES, respectively) using ultrafast ultrasonography to assess arterial stiffness. The right and left common carotid arteries were measured separately, and laboratory metabolic parameters were also collected. Participants were balanced between groups using propensity score matching (PSM) at a 1:1 ratio, adjusting for age, sex, and waist-to-hip ratio as potential confounders. Cutoff values of ufPWV for monitoring subAS were determined via receiver operating characteristic (ROC) curve analysis.
Results:
PWV-ES, unlike PWV-BS, was higher in the subAS subgroup than in the subAS-free group after PSM (all P<0.05). For each 1 m/s increase in left, right, and bilateral mean PWV-ES, the risk of subAS increased by 23% (95% confidence interval [CI], 1.04 to 1.46), 26% (95% CI, 1.07 to 1.52), and 38% (95% CI, 1.12 to 1.72), respectively. According to ROC analyses, predictive potential was found for left PWV-ES (cutoff value=7.910 m/s, P=0.002), right PWV-ES (cutoff value=6.615 m/s, P=0.003), and bilateral mean PWV-ES (cutoff value=7.415 m/s, P<0.001), but not for PWV-BS (all P>0.05).
Conclusion
PWV-ES measured using ultrafast ultrasonography was significantly higher in individuals with subAS than in those without. Specific PWV-ES cutoff values showed potential for predicting an increased risk of subAS.

ObjectiveTo apply pneumatic hand rehabilitation equipment in comprehensive rehabilitation training to improve hand function in children with spastic hemiplegic cerebral palsy. MethodsFrom Januray, 2020 to September, 2021, 58 children with spastic hemiplegia cerebral palsy in Maternity and Child Health Care Hospital of Nantong University were randomly divided into control group (n = 29) and experimental group (n = 29). Both groups accepted comprehensive rehabilitation training, while the experimental group accepted pneumatic hand rehabilitation equipment training in addition, for six months. They were assessed with Peabody Developmental Motor Scales-Fine Motor (PDMS-FM), Fine Motor Function Measurement (FMFM) and Wee-Function Independence Measure (Wee-FIM) before and after training. ResultsThe scores of PDMS-FM, FMFM and Wee-FIM improved in both groups after training (|t| > 16.310, P < 0.001), and improved more in the experimental group than in the control group (t > 2.795, P < 0.01). ConclusionApplication of pneumatic hand rehabilitation equipment in comprehensive rehabilitation training can effectively promote the recovery of hand function for children with spastic hemiplegic cerebral palsy.

Early childhood caries (ECC) is a significant chronic disease of childhood and a rising public health burden worldwide. ECC may cause a higher risk of new caries lesions in both primary and permanent dentition, affecting lifelong oral health. The occurrence of ECC has been closely related to the core microbiome change in the oral cavity, which may be influenced by diet habits, oral health management, fluoride use, and dental manipulations. So, it is essential to improve parental oral health and awareness of health care, to establish a dental home at the early stage of childhood, and make an individualized caries management plan. Dental interventions according to the minimally invasive concept should be carried out to treat dental caries. This expert consensus mainly discusses the etiology of ECC, caries-risk assessment of children, prevention and treatment plan of ECC, aiming to achieve lifelong oral health.

Objective:To investigate the epidemic status and molecular characteristics of Borrelia burgdorferi in ticks in Xinjiang Uygur Autonomous Region (referred to as Xinjiang). Methods:From April to June 2020, 312 samples of Ixodes were collected in 6 areas of Yili, Alashankou, Hutubi, Qinghe, Fuhai and Wujiaqu, Xinjiang. Nested PCR and fluorescence quantitative PCR were used to detect Borrelia burgdorferi in ticks. The positive samples by both methods were genotyped and identified by nested PCR products. Results:The positive rates of nested PCR and fluorescence quantitative PCR were 8.97% (28/312) and 11.86% (37/312), respectively. Among them, the fluorescence quantitative PCR positive rate of Qinghe was the highest of 35.29% (12/34), and the positive rate of Fuhai was the lowest of 2.00% (1/50). The positive samples by both methods was 26. Genotyping results showed that 12 samples were highly homologous to Borrelia garinii, 10 copies to Borrelia burgdorferi sensu stricto, and 4 copies to Borrelia afzelii. Conclusions:The positive rate of Borrelia burgdorferi in ticks in Xinjiang is higher, which has confirmed that there are 3 pathogenic Borrelia burgdorferi genotypes in Xinjiang. The dominant genotype is Borrelia garinii, followed by Borrelia burgdorgferi sensu stricto genotype and Borrelia afzelii genotype.
