Background: To evaluate the effectiveness of individualized-dose polyethylene glycol recombinant human growth hormone (PEG-rhGH) for short stature. Methods: This real-world study enrolled children with short stature in 19 hospitals throughout China. They were treated with PEG-rhGH for 6 months. The starting dosage ranged from 0.10 to 0.20 mg/kg/week. The primary outcome was the change in height standard deviation score (ΔHt SDS). Results: Five hundred and ten patients were included and grouped based on dosage as A (0.10–0.14 mg/kg/week), B (0.15–0.16 mg/kg/week), C (0.17–0.19 mg/kg/week), and D (0.20 mg/kg/week). The mean 6-month ΔHt SDS for the total cohort was 0.49 ± 0.27, and the means differed among the four dose groups (P = 0.002). The ΔHt SDS was lower in group A than in groups B (LSM difference [95%CI], -0.09 [-0.17, -0.01]), C (LSM difference [95%CI], -0.10 [-0.18, -0.02]), and D (LSM difference [95%CI], -0.13 [-0.21, -0.05]) after adjusting baseline covariates. There were no significant differences among groups B, C, and D. When the baseline IGF-1 was < -2 SDS or > 0 SDS, the △Ht SDS was not different among the four groups (P = 0.931 and P = 0.400). In children with baseline IGF-1 SDS of -2 ~ 0 SDS, a higher dosage was associated with a better treatment effect (P = 0.003), and the △Ht SDS was lower in older children than in younger ones (P < 0.001). Conclusions: PEG-rhGH could effectively increase height in prepubertal short children. When the baseline IGF-1 was < -2 SDS, 0.10 mg/kg/week could be a starting dose. In other IGF-1 statuses, 0.15–0.20 mg/kg/week might be preferred. Trial registration: ClinicalTrials.gov: NCT03249480, retrospectively registered. [ABSTRACT FROM AUTHOR]

Background: This population-based cross-sectional study aimed to evaluate the prevalence of oral mucosal lesions (OMLs) in children in a rural area in China as epidemiological data on these conditions from such areas are insufficient. Methods: A total of 3145 children in Xiangyun of Yunnan were enrolled. A socio-economic questionnaire and a field survey of OMLs were administered. We gathered information on factors (sex, age, caregiver, parental education, and last-month household income) that might be associated with OMLs in these children. Results: OMLs in children in Xiangyun of Yunnan had a prevalence of 1.8% (95% CI; 1.3–2.3%). The most prevalent OML was oral ulcer (n = 11; 18.3%), followed by linea alba (n = 10; 16.7%), whereas the least prevalent OMLs were frenal tag (n = 1; 1.7%) and herpes labialis (n = 1; 1.7%). On unadjusted or adjusted regression, school-aged children had about 50% lower risk of OMLs than preschoolers. Conclusions: These findings indicate that the prevalence of OMLs in Xiangyun of Yunnan is lower than previously reported. Additionally, the age might be associated with the occurrence of OMLs in children in Xiangyun of Yunnan, China. [ABSTRACT FROM AUTHOR]

Objective. To study the correlation between Traditional Chinese Medicine (TCM) constitution and dyslipidemia. Methods. CNKI, VIP, Wanfang database, CBMdisc, PubMed, and Embase were searched, and meta-analysis was performed by Review Manager 5.2 software. Results. Altogether 11 studies were included with 12890 individuals. The results showed that balanced constitution was a protective factor of dyslipidemia (OR = 0.62, 95% CI 0.47~0.82) while phlegm-dampness constitution was a risk factor of it (OR = 2.50, 95% CI 2.22~2.80), and the effect of phlegm-dampness constitution in South China (OR = 3.31, 95% CI 1.71~6.43) was more obvious than that in East (OR = 2.40, 95% CI 2.06~2.80) and North China (OR = 2.24, 95% CI 1.81~2.78). Conclusion. This study provides evidence for the prevention and treatment of dyslipidemia in TCM. However, most of the studies included are of moderate quality; more high quality, multicenter, large-sample studies are expected to provide higher level evidence. [ABSTRACT FROM AUTHOR]

Henoch–Schönlein purpura (HSP) is a multifactorial inflammatory disease whose pathogenesis remains unknown. Pyrin encoded by the MEFV gene (NM_000243; OMIM 608107) is an important active member of the inflammasome and has been shown to affect the expression of many of the genes involved in immune and inflammatory responses. The aim of our study was to elucidate the possible roles of MEFV genetic variants on the susceptibility to HSP and its clinical outcomes in 78 patients with HSP and 189 controls in China. A significant association was found between the E148Q polymorphism (G->C) and HSP susceptibility (odds ratio 2.76, 95% confidence interval 1.76-4.34, P=0.0001). The C allele of E148Q was associated with joint involvement ( P = 0.014) but not with HSP nephritis ( P = 0.1). The clinical score was higher in subjects with the CC genotype than in those with the CG or GG genotype (4.13 ± 3.53 vs. 1.94 ± 1.70, respectively; P = 0.011). P369S was not associated with HSP or other phenotypes. M694V and M680I were absent in our patients. Our results suggest that MEFV E148Q could be a contributory genetic factor to HSP and HSP-related joint syndromes. [ABSTRACT FROM AUTHOR]
