Individualized treatment of pediatric inguinal hernia reduces adolescent recurrence rate: an analysis of 3006 cases.

Purpose: We implemented the individualized treatment (IT) regimen for children with inguinal hernia and the Lichtenstein hernioplasty using an acellular tissue matrix patch (LHAP) for those with high risks. This retrospective study compares the complications of conventional laparoscopic high hernia sac ligation (LHSL) with those of the IT regimen for the management of pediatric inguinal hernia and investigates whether the recurrence rate of inguinal hernias in children treated by IT is lower than that of those treated by LHSL.

Methods: The subjects of this retrospective study were 3006 children who underwent LHSL or IT for inguinal hernia between February, 2008 and February, 2016 at the Beijing Chao-Yang Hospital (Beijing, China).

[Seasonal dynamics and vertical distribution pattern of bud bank in different erosion environments on hilly-gully Loess Plateau of Northwest China].

This paper studied the vegetation composition, bud composition, and the seasonal dynamics and vertical distribution pattern of bud bank in five erosion environments (sunny gully slope, sunny hilly slope, hilltop, shady hilly slope, and shady gully slope) on the hilly-gully Loess Plateau of North Shaanxi. In the study area, the perennial species with perennial bud bank accounted for 80.3% of the total species, while the annual species with seasonal bud bank took up 19.

[Ecological adaptability of leaf epidermis of erosion-resistant plants in hilly-gully area of Loess Plateau, Northwest China].

By the temporary slide method of leaf epidermis, an observation was made on the morphological characteristics of the leaf epidermis of six erosion-resistant plant species in different soil erosion environments (gully, inter-gully, and inter-gully artificial Robinia pseudoacacia forest land) in hilly-gully area of Loess Plateau. Compared with those in the gully, the stomata aperture, stomata density, stomata index, stomata apparatus length/width plasticity, stomata apparatus area plasticity, epidermal hair density, and epidermal cell density of the leaf upper and lower epidermis of the plants in the inter-gully were 93.8% and 90.
