Treatment of chronic urticaria with traditional Chinese medicine: A systematic review, meta-analysis, and medication regularity.

Background: Traditional Chinese medicine (TCM) is often used to treat chronic urticarial (CU), so its efficacy and safety on CU were studied according to systematic review and meta-analysis.

Methods: By searching PubMed, Wanfang, CNKI, and other databases for the literature on the treatment of CU with TCM in the past 10 years (2013-2023), the PICOS principle was used as the criterion for inclusion and exclusion of literature, and the quality of the included literature studies was systematically reviewed according to the Cochrane systematic review method and software RevMan5.3.

Multifunctional Flexible Hard Coatings with Weathering Resistance and Heat-Shielding Properties.

Hard, flexible, transparent, and hydrophobic multifunctional coatings have a wide range of applications, but they do not adequately protect against harsh conditions, especially photoaging. In this study, SiO and AlO nanoparticles were first modified by silazane and epoxy-functionalized silanes and then reacted with a polyetheramine curing agent to prepare highly crosslinked multifunctional hybrid coatings at room temperature. Due to the integration of siloxane nanoparticles and a polymer network, the multifunctional coatings presented outstanding hardness (4H), flexibility (bending diameter of 10 mm), and transmittance (>97%).

The β-catenin/CBP signaling axis participates in sepsis-induced inflammatory lung injury.

Sepsis-induced inflammatory lung injury is a key factor causing failure of the lungs and other organs, as well as death, during sepsis. In the present study, a caecal ligation and puncture (CLP)-induced sepsis model was established to investigate the effect of β-catenin on sepsis-induced inflammatory lung injury and the corresponding underlying mechanisms. C57BL/6 mice were randomly divided into five groups, namely, the sham, CLP, β-catenin knockout (KO) + CLP, XAV-939 + CLP, and ICG-001 + CLP groups; the XAV-939 + CLP and ICG-001 + CLP groups were separately subjected to intraperitoneal injections of the β-catenin inhibitors XAV-939 and ICG-001 for 1 week preoperatively and 2 days postoperatively, respectively.

Increased expression of TIGIT and KLRG1 correlates with impaired CD56 NK cell immunity in HPV16-related cervical intraepithelial neoplasia.

Background: The onset and progression of cervical intraepithelial neoplasia (CIN) are closely associated with the persistent infection of high-risk HPV (especially type16), which is mainly caused by immune escape. Natural killer (NK) cells play an important role against virally infected cells and tumor cells through a fine balance of signals from multiple surface receptors. Overexpression of non-MHC-I specific inhibitory receptors TIGIT, KLRG1, Siglec-7, LAIR-1, and CD300a on NK cells correlates with cellular exhaustion and immune evasion, but these receptors have not been investigated in CIN.

Effect of immunotherapy on the immune microenvironment in advanced recurrent cervical cancer.

This study evaluated the basic immune status of cervical cancer and the influences of immunotherapy on the immune microenvironment, and analyzed the correlation between changes in the immune microenvironment and prognosis. We retrospectively analyzed the treatment status of 8 patients with advanced recurrent cervical cancer treated with PD-1 inhibitors and detected the tumor-infiltrating immune markers (CD3, CD4, CD8, CD20, CD56, CD68, PD-1, and PD-L1) by immunohistochemistry. All patients showed good tolerance during the treatment.

Omnidirectional / Unidirectional Antireflection-Switchable Structures Inspired by Dragonfly Wings.

Randomly arranged irregular inclined conical structure-covered dragonfly wings, distinguished from periodic conical structure-covered cicada wings, are with high optical transparency for wide viewing angles. Bioinspired by the antireflective structures, we develop a colloidal lithography approach for engineering randomly arranged irregular conical structures with shape memory polymer-based tips. The structures establish a gradual refractive index transition to suppresses optical reflection in the visible spectrum.

Leafhopper Wing-Inspired Broadband Omnidirectional Antireflective Embroidered Ball-Like Structure Arrays Using a Nonlithography-Based Methodology.

Leafhoppers () actively coat their wings with embroidered ball-like secretory brochosomes, which act as antireflective structures to enhance camouflage against predators. Inspired by the leafhoppers, we report a scalable nonlithographic approach for self-assembling nonclose-packed embroidered ball-like hierarchical structure arrays. The resulting structures create a gradual refractive index transition at the air/substrate interface, thereby suppressing the optical reflection for wide viewing angles.

Reversibly Erasable Broadband Omnidirectional Antireflection Coatings Inspired by Inclined Conical Structures on Blue-Tailed Forest Hawk Dragonfly Wings.

Blue-tailed forest hawk dragonfly () wings, covered with inclined conical structures, are studied for their high transparency and low reflectance for large viewing angles. However, limited by existing technologies, the exquisite inclined structures are not replicated easily or applied adequately. Here, we combine a shear-induced self-assembly approach and a colloidal lithography technology to create omnidirectional antireflection structures that are inspired by dragonfly wings.
