Introduction: This study aims to identify the therapeutic outcomes of punch excision in severe burn patients with extensive, excessive and long-lasting growth scars.

Methods: A retrospective comparative clinical observational study was conducted on patients with burn hypertrophic scars who were treated at the Department of Burn and Skin Wound Repair, First Hospital of Jilin University, between October 2022 and October 2024.

Results: A total of 49 patients with severe burn scars were included.

Combination therapy of pulsed dye laser and ablative fractional carbon dioxide laser for the treatment of pediatric postburn scar: a systematic review.

This study aims to determine the effectiveness of combining pulsed dye laser (PDL) and ablative fractional carbon dioxide laser (AFCL) in the treatment of scars in pediatric patients, as well as to identify appropriate treatment parameters, initial treatment timing, and treatment intervals through a systematic literature review. A literature search was conducted between April 6, 2014 and April 6, 2024 in four databases to select studies on the effects of the combination of carbon dioxide fractional laser and pulsed dye laser therapy in children hypertrophic burn scars. This systematic literature review included 497 participants across 8 studies, with individual study sample sizes ranging from 17 to 125 participants.

Adaptive carrier-phase-noise-canceled LiDAR for range-Doppler imaging beyond hundreds of laser coherence length.

Carrier-phase noise limits both the performance and the maximum operation range of coherent LiDAR. To address this issue, we propose a carrier-phase-noise-canceled LiDAR based on an auxiliary interferometer and adaptive filters. Compared to previous methods, this approach is calibration-free and offers higher compensation accuracy, as well as applicability of dynamic target detection.

Wood-based capillary enhancers for accelerated moisture capture and solar-powered release.

The pressing need to address the global water crisis has spurred research efforts toward exploring alternative sources and technologies, and harvesting atmospheric water from the humid air emerges as a promising solution. Liquid desiccants, known for their high absorption capacity, have been widely utilized for moisture capture, but their water yield is mainly restricted by sluggish adsorption and desorption dynamics. To address this limitation, we present a facile strategy to promote the absorption/desorption dynamics of moisture by virtue of capillary transport and enlarged interfaces in a photothermal wood enhancer.

Mass-ratio and complementarity effects simultaneously drive aboveground biomass in temperate forests through stand structure.

Forests play a key role in regulating the global carbon cycle, a substantial portion of which is stored in aboveground biomass (AGB). It is well understood that biodiversity can increase the biomass through complementarity and mass-ratio effects, and the contribution of environmental factors and stand structure attributes to AGB was also observed. However, the relative influence of these factors in determining the AGB of forests remains poorly understood.

The lncRNA CASC9 alleviates lipopolysaccharide-induced acute kidney injury by regulating the miR-424-5p/TXNIP pathway.

Objective: This study aimed to clarify the mechanism by which the long non-coding RNA cancer susceptibility candidate 9 (CASC9) alleviates sepsis-related acute kidney injury (S-AKI).

Methods: A lipopolysaccharide (LPS)-induced AKI model was established to simulate S-AKI. HK-2 human renal tubular epithelial cells were treated with LPS to establish an model, and mice were intraperitoneally injected with LPS to generate an model.

Suspended Membrane Evaporators Integrating Environmental and Solar Evaporation for Oily Wastewater Purification.

Solar-driven evaporation is promising in oily wastewater treatment, in particular for emulsions, but conventional evaporators suffer from pore blocking by residual oil or contamination by volatile oil compounds in the condensed water. In the current research, we develop a suspended membrane evaporator integrating solar evaporation with oil-in-water emulsion separation. The heating and evaporating interface is separated from the rejecting interface to avoid oil escape and improve heat management.

Sandwich-Structured Photothermal Wood for Durable Moisture Harvesting and Pumping.

Moisture capture coupled with photothermal regeneration provides an alternative and sustainable way to acquire fresh water. Composite moisture absorbents based on hygroscopic salts are environmentally friendly, economically feasible, and of high efficiency but suffer from the unavoidable desiccant leakage during absorption and evaporation-induced salt accumulation on material surfaces during desorption. In this study, we develop a superhydrophobic-hydrophilic-hydrophobic photothermal wood embedded with CaCl to promote the durability of the absorbents.

Biodiversity increased both productivity and its spatial stability in temperate forests in northeastern China.

Although the relationship between biodiversity and ecosystem functioning has been extensively studied, it remains unclear if the relationships of biodiversity with productivity and its spatial stability vary along productivity gradients in natural ecosystems. Based on a large dataset from 2324 permanent forest inventory plots across northeastern China, we examined the intensity of species richness (SR) and tree size diversity (Hd) effects on aboveground wood productivity (AWP) and its spatial stability among different productivity levels. Structural equation modeling was applied, integrating abiotic (climate and soil) and biotic (stand density) factors.

['s experience and practice in treatment of stroke].

is the famous acupuncture scholar in modern times and he emphasizes the importance of moxibustion in the diagnosis and treatment of stroke. According to the different stages and types of stroke, the full-period moxibustion treatment is dominant, i.e.

The expression of IL-1β can deteriorate the prognosis of nervous system after spinal cord injury.

Purpose: We used Anakinra to inhibit the expression of IL-1β based on the model of spinal cord injury in the rat stomach and explored whether it had a certain neuroprotective effect after spinal cord injury.

Materials And Methods: The spinal cord injury model of four segments (T5-T8) was prepared by using vascular clamp. Thirty rats were randomized to the control group and the experimental group, and the control group used normal saline, while the experimental group used Anakinra after spinal cord injury.

Dexamethasone attenuates development of monocrotaline-induced pulmonary arterial hypertension.

Immunity and inflammation are well established factors in the pathogenesis of pulmonary arterial hypertension (PAH). We aimed to investigate whether dexamethasone (Dex), a potent immunosuppressant, could prevent the development of monocrotaline (MCT)-induced PAH in rats as compared with pyrrolidine dithiocarbamate (PDTC) and its effect on the immune mechanism. PAH in rats (n = 66) was induced by MCT (50 mg/kg) injected intraperitoneally.

[Clinical study on electroacupuncture combined with manual acupuncture for treatment of simple obesity].

Objective: To compare therapeutic effects of electroacupuncture combined with manual acupuncture and simple electroacupuncture on simple obesity.

Methods: One hundred and twenty cases were randomly divided into an electroacupuncture plus manual acupuncture group (observation group, n = 63) and a simple electroacupuncture group (electroacupuncture group, n = 57). Their clinical therapeutic effects and the time starting the therapeutic effect were compared.

[Magnetic resonance imaging findings in children with cerebral palsy].

Objective: To study the clinical and neurological abnormalities in children with cerebral palsy (CP) and to attempt to correlate the types of CP and the gestational age at birth with radiological abnormalities detected by magnetic resonance imaging (MRI) of the brain.

Methods: This is a hospital-based study, the subjects included 104 children with cerebral palsy who were hospitalized in the Qingdao Rehibilitation Center For Disabled Children. All the 104 hospitalized CP cases (47 with spastic diplegia, 9 with tetraplegia, 15 with hemiplegia, 22 with athetosis, and 11 with ataxia) were examined neurologically and their perinatal history was reviewed.
