A short-term functional recovery comparison of therapeutic plasma exchange and immunoadsorption in severe acute neuroimmune diseases.

Objective: To compare the differential impact of recombinant protein A immunoadsorption (PAIA) or therapeutic plasma exchange (TPE) on neurological functional improvement and quality of life in patients afflicted with severe acute neuroimmune diseases, including Guillain-Barré syndrome (GBS), myasthenia gravis (MG), neuromyelitis optica spectrum disorder (NMOSD), and anti-NMDA receptor encephalitis (NMDARE).

Methods: The retrospective study included 29 patients with moderate to severe disability (modified Rankin scale, mRS≥3) due to acute neuroimmune diseases at the second Xiangya hospital from January 2021 to January 2023. The clinical efficacy of PAIA and TPE in improving neurological function (ΔmRS≥1) and the difference in favorable functional outcomes (mRS 0-2) at three months were evaluated.

Chinese Medicine as Supporting Therapy for Psoriasis: Past, Present, and Future.

Psoriasis is a chronic skin disease and an important health concern. Western medicine and therapies are the main treatment strategies for psoriasis vulgaris (PV); however, the overall prognosis of patients with PV is still poor. Therefore, PV prevention is especially crucial.

LncRNA KCNQ1OT1 promotes the metastasis of ovarian cancer by increasing the methylation of EIF2B5 promoter.

Background: Long non-coding RNAs (lncRNAs) have emerged as regulators of human malignancies, including ovarian cancer (OC). LncRNA KCNQ1OT1 could promote OC progression, and EIF2B5 was associated with development of several tumors. This project was aimed to explore the role of lncRNA KCNQ1OT1 in OC development, as well as the involving action mechanism.

[Yishen Tonglong Decoction inhibits the epithelial-mesenchymal transition and Ras/ERK signaling pathway in human prostate cancer DU-145 cells].

Objective: To observe the effect of Yishen Tonglong Decoction (YTD) on the epithelial-mesenchymal transition (EMT) and Ras/ERK signaling pathway in human PCa DU-145 cells and explore its action mechanism.

Methods: We treated human PCa DU-145 cells with normal plasma (the blank control) or plasma containing 5% (low-dose), 10% (medium-dose) and 15% (high-dose) YTD. After intervention, we examined the proliferation of the DU-145 cells in different groups with CCK-8 and their apoptosis by Annexin V/PI double staining.

Ultrastable radical-doped coordination compounds with antimicrobial activity against antibiotic-resistant bacteria.

In the present work, we have introduced a series of stable radical-doped coordination compounds composed of donor-acceptor structures and shown to produce organic radicals in situ as a result of unconventional lone pair-π interactions in ambient conditions. Inconspicuous lone pair-π and C-Hπ interactions were shown to play a key role in self-assembly as well as the charge transfer process, resulting in a long-lived charge-separated state able to generate organic radicals. The resultant species displayed broad-spectrum antimicrobial activity, including against multi-drug-resistant bacteria.

LncRNA KCNQ1OT1 sponges miR-15a to promote immune evasion and malignant progression of prostate cancer via up-regulating PD-L1.

Background: We focused on the KCNQ1OT1/miR-15a/PD-L1 axis and explored its significance in regulating immune evasion and malignant behaviors of prostate cancer (PC) cells.

Methods: The expression levels of KCNQ1OT1, miR-15a, PD-L1, and CD8 in cells or tissues were examined by RT-qPCR, western blot or immunohistochemistry (IHC) assays. The direct regulations between KCNQ1OT1, miR-15a and PD-L1 were validated by luciferase reporter assay.

[Effects of Yishen Tonglong Capsules on sex hormone levels in mice with benign prostatic hyperplasia].

Objective: To study the effect of Yishen Tonglong Capsules (YTC) on the sex hormone levels in the mouse model of benign prostatic hyperplasia (BPH).

Methods: The BPH model was made in male mice by subcutaneous injection of testosterone propionate at 5 mg per kg of the body weight per day for 3 weeks. Then the model animals were divided into five groups of 10 in each: model control, Longbishu Capsules (LBS), and high-, medium- and low-dose YTC.

[Qianlongtong capsule elevates the Smad4 gene expression in prostate stromal cells].

Objective: To investigate the effects of the plasma containing Qianlongtong Capsule (QLT)-containing plasma on the expression of the Smad4 gene in prostate stromal cells in vitro and provide some experimental evidence for the treatment of benign prostatic hyperplasia (BPH) with Chinese medicinal compound.

Methods: Fifteen cases of BPH were equally randomized to three groups to be treated with QLT at a high dose (6 capsules once), a medium dose (3 capsules once), and a low dose (1.5 capsules once), tid, for 7 days consecutively.

The role of aromatic L-amino acid decarboxylase in bacillamide C biosynthesis by Bacillus atrophaeus C89.

For biosynthesis of bacillamide C by Bacillus atrophaeus C89 associated with South China sea sponge Dysidea avara, it is hypothesized that decarboxylation from L-tryptophan to tryptamine could be performed before amidation by the downstream aromatic L-amino acid decarboxylase (AADC) to the non-ribosomal peptide synthetases (NRPS) gene cluster for biosynthesizing bacillamide C. The structural analysis of decarboxylases' known substrates in KEGG database and alignment analysis of amino acid sequence of AADC have suggested that L-tryptophan and L-phenylalanine are the potential substrates of AADC. The enzymatic kinetic experiment of the recombinant AADC proved that L-tryptophan is a more reactive substrate of AADC than L-phenylalanine.
