This study aimed to evaluate the effects of thyroid hormone supplementation on growth rate of children with idiopathic short stature (ISS) and low-normal serum free thyroxine FT4 who were receiving growth hormone therapy. We selected 64 prepubertal children with FT4 levels in the lowest third of the normal range as the lower FT4 group, and these children were divided randomly into two subgroups: L-thyroxine (L-T4)-treated subgroup was treated with L-T4 (0.5-3.0 g/(kg·d)) from the beginning of the study, and the non-L-T4-treated subgroup received placebo. We also selected 39 ISS children with FT4 in the upper two-thirds of the normal range as the higher FT4 group. During the first year, the lower FT4 group featured lower FT3, FT4, thyroid stimulating hormone (TSH), and insulin-like growth factor-I standard deviation score (IGF-I SDS) and significantly lower height velocity (HV) compared with the higher FT4 group. However, in the lower FT4 group, the L-T4-treated subgroup presented higher FT4, FT3, TSH, and IGF-I SDS concentrations and significantly higher HV compared with children in the non-L-T4-treated subgroup. In children with ISS, the negative effect of thyroid hormone deficiency on growth rate should be considered when FT4 level lies in the low-normal range prior to recombinant human growth hormone treatment.

The structural characteristics of the tree crowns of Cunninghamia lanceolata var. Luotian(herein, Luotian), a natural variety of C. lanceolata(Chinese-fir, herein Lanceolata) in China, were analyzed using trunk and branch measurements and biomass determinations. Samples from two typical cultivated varietal populations were collected, including twenty-six 15–23-year-old trees of Luotian from a plantation, and nine 16–23-year-old trees of Lanceolata. Our results show that Luotian and Lanceolata samples differed significantly in crown structure, morphological indices, and biomass:(1) the oldest live branches on Luotian trees were 5–6 years old and 8–11 years old on Lanceolata. The ages of the live branches were not affected by the ages of the Luotian trees, while live branch ages increased with ages of Lanceolata trees;(2) the maximumbranching order of Luotian was level two. Compared to Lanceolata, the average number of first-order lateral branches(i.e., branches emerging from the trunk) and the number of first-order lateral branch whorls per sample tree were 12.9% and 32.2% lower, respectively, in ***, the average number of branches within a single whorl was 21.8% greater in Luotian;the average number of branch whorls at crown height was 51.1% greater. Thus,the Luotian variety has thicker branches;(3) the average lateral branch angles in Luotian and Lanceolata sample trees were 105.2° and 61.4°, respectively. The branch angles in 53.0% of lateral branches on Luotian ranged from105° to 135°, but 30° to 90° in 96% of the lateral branches on Lanceolata. Within the same crown layer, the average branch angle was 1.6–2.2 times greater in Luotian, and the angle was directly proportional to crown thickness;(4) the average base diameter and branch length on Luotian were1.3 cm and 75.8 cm, respectively, and 1.6 cm and112.2 cm for Lanceolata. For individual trees, branch growth differed significantly(p < 0.01) between Luotian and Lanceolata. However, the lateral bran

High entropy alloys(HEAs) with adjustable composition and diverse surface active sites show good catalytic performance of methanol oxidation reaction(MOR). However, the synthesis and morphology control of HEA remains a challenge. Herein, we use a fast co-reduction method to synthesize a series of ultrathin wavy nanowires(WNWs) with an average diameter of 3–5 nm, including Pt-based and Pd-based binary alloys, and HEA with different pairs of immiscible elements. The catalytic properties of Pt Pd Ag Cu Ni WNWs show that the mass activity and stability of Pt Pd Ag Cu Ni WNWs is higher than Pt and Pd WNWs. Meanwhile we explored the cocktail effect among high entropy alloy elements through annealing. The cocktail effect among the metal elements in Pt Pd Ag Cu Ni WNWs provided more active sites with increased metal-metal interactions, thus improving the catalytic efficiency.
