Do Community Home-Based Elderly Care Services Improve Life Satisfaction of Chinese Older Adults? An Empirical Analysis Based on the 2018 CLHLS Dataset.

Population aging has become a major challenge for the Chinese government. Based on the Chinese Longitudinal Healthy Longevity Survey (CLHLS) in 2018, this study adopts the propensity score matching (PSM) method to assess the effect of community home-based elderly care services (CHECS) on the life satisfaction of the elderly in China. The results demonstrate that CHECS can improve their life satisfaction.

Dietary ellagic acid supplementation attenuates intestinal damage and oxidative stress by regulating gut microbiota in weanling piglets.

Intestinal oxidative stress triggers gut microbiota dysbiosis, which is involved in the etiology of post-weaning diarrhea and enteric infections. Ellagic acid (EA) can potentially serve as an antioxidant supplement to facilitate weaning transition by improving intestinal oxidative stress and gut microbiota dysbiosis. Therefore, we aimed to investigate the effects of dietary EA supplementation on the attenuation of intestinal damage, oxidative stress, and dysbiosis of gut microbiota in weanling piglets.

A 3D visualization layered anatomy for acromial arterial rete and flap design.

Background: The acromial arterial rete (AAR) is the junction between the skin blood supply of the cervical side and that of the upper arm, and it is the only site crossed by the trans-regional blood supply of the cervico-humeral flap (CHF). The aim of this study was to explore the structures of AAR to optimizing flap design.

Methods: A body arteriography and spiral CT scan were performed on 33 whole adult corpses.

Three-Dimensional Visualization for Extended Deep Inferior Epigastric Perforator Flaps.

Purpose: The aim of the study was to provide an applied and digital anatomical basis of acquiring extended deep inferior epigastric perforator (DIEP) flaps for clinical use.

Methods: Five formalin-soaked specimens were received red latex injection and dissected by layers. The arteriography using the modified mixture of lead oxide-gelatin was performed on 10 adult cadavers that were serially scanned by a spiral computed tomography.

A Dopant Replacement-Driven Molten Salt Method toward the Synthesis of Sub-5-nm-Sized Ultrathin Nanowires.

The high-temperature molten-salt method is an important inorganic synthetic route to a wide variety of morphological phenotypes. However, its utility is limited by the fact that it is typically incapable of producing ultrathin (<5 nm diameter) nanowires, which have a crucial role in novel nanotechnology applications. Herein, a rapid molten salt-based synthesis of sub-5-nm-sized nanowires of hexagonal tungsten oxide (h-WO ) that is critically dependent on a substantial proportion of molybdenum (Mo) dopant is described.

Comparative Study of Choke Vessel Reconstruction With Single and Multiple Perforator-Based Flaps on the Murine Back Using Delayed Surgery.

Objective: Choke vessels, vascular anastomosis between adjacent angiosome, play an important role in flap expansion and survival. Here we established a flap model with single and multiple perforators to detect and compare the changes in choke vessels, discuss the effect of hemodynamics on the vascular morphology, and explore the underlying mechanism.

Methods: One hundred mice (7-8 weeks) were subjected to a "choke zone" surrounded by 4 perforators on their backs.

Analytical fuzzy approach to biological data analysis.

The assessment of the physiological state of an individual requires an objective evaluation of biological data while taking into account both measurement noise and uncertainties arising from individual factors. We suggest to represent multi-dimensional medical data by means of an optimal fuzzy membership function. A carefully designed data model is introduced in a completely deterministic framework where uncertain variables are characterized by fuzzy membership functions.

Comparative study of 3D reconstruction of rat sciatic nerve microvessels using Evans blue and lead oxide.

Background: The blood supply of peripheral nerve grafts is one of the important factors that affect nerve regeneration. Many investigators have studied how intraneural microvessels are distributed and ways to promote the angiogenesis of grafts. However, there still does not exist an ideal intraneural microvascular model.

[A trail of three-dimensional visualization technique to observe intraneural microvessels of sciatic nerves in Sprague Dawley rats].

Objective: To investigate the feasibility of establishing the visualization models of intraneural microvessels of sciatic nerves in Sprague Dawley (SD) rats by systemic infusion of Evan's blue (EB) or lead oxide and to compare the advantages and disadvantages.

Methods: Fifteen healthy adult SD rats of either gender, weighing 200-250 g, were randomly divided into traditional group (group A, n=5), fluorescence group (group B, n=5), and radiography group (group C, n=5). Ink, EB, and lead oxide, all mixed with gelatin solution, were injected in groups A, B, and C, respectively.

Three-dimensional analysis of perforators of the posterior leg.

Background: Three-dimensional evaluations of cutaneous perforator vessels provide useful clinical information to aid in the design of perforator flaps. By combining three-dimensional digital imaging and angiography, the authors developed a new three-dimensional visualization technique for vascular perforators. Their purpose was to produce a digitized model of the posterior leg to determine the anatomical relationships of perforators in each zone of the posterior leg.
