Anterior segment optical coherence tomography for superficial keratectomy.

PURPOSE: To report the use of anterior segment optical coherence tomography (AS-OCT) for superficial keratectomy (SK) in anterior corneal opacity. METHODS: The characteristics of 43 eyes (39 patients) with various lesions responsible for anterior corneal opacity were included in this retrospective non-comparative study. AS-OCT was performed on all eyes before surgery. The thickness of corneal opacity and the underlying healthy stroma were measured. SK was performed on each individual. RESULTS: Four types of anterior corneal opacity were evaluated, including corneal degeneration (26/43), Reis-Bücklers corneal dystrophy (8/43), alkali burn (1/43) and corneal tumors (8/43). Based on AS-OCT images, all eyes showed abnormal hyper-reflective signals in the superficial cornea to less than one-third of the normal corneal thickness in the deepest corneal opacity. All 43 eyes underwent an SK procedure. In addition, 1 eye with alkali burns and 7 eyes with corneal tumors were combined with amniotic membrane transplantation. All eyes restored transparency without significant complications. CONCLUSION: AS-OCT is a valuable method for objective preoperative and noninvasive assessments of anterior corneal opacities and is useful for guiding SK.

A multicenter, open-label, parallel-group, randomized controlled trial of Tongluo-Qutong rubber plaster for the treatment of cervical spondylotic radiculopathy.

BACKGROUND: In China, Tongluo-Qutong rubber plaster (TQRP) is commonly used for cervical spondylotic radiculopathy, but lacks high-quality trials. OBJECTIVE: This study aimed to conduct a multicenter, open-label, parallel-group, randomized controlled trial in China to investigate the practical efficacy and safety of TQRP in the treatment of CSR. METHODS: A total of 240 patients diagnosed with CSR were recruited for the investigation from multiple hospitals in Gansu province, China. The patients were randomly assigned to either an experimental or a control group. The experimental group received treatment with TQRP, whereas the control group was administered a diclofenac sodium patch (DSP) for a maximum duration of 21 days. The visual analogue scale (VAS) score for pain, the proportion of patients experiencing 50% or more pain relief, the neck disability index (NDI), changes as per the Eaton trial, and recurrence during the follow-up period were evaluated for both groups. The safety and adverse events associated with the concurrent drug therapy were also evaluated. RESULTS: At each time point, the mean VAS and NDI scores of both groups demonstrated a downward trend. The experimental group exhibited a greater decline in VAS score at each time point compared to the control group (P< 0.01). In the Eaton trial, both the percentage of patients experiencing pain relief of 50% or more and the number of abnormal results exhibited improvement. However, the outcomes in the 21 ± 3d experimental group were significantly superior to those in the control group (P< 0.01). During the follow-up period, the recurrence events in the experimental group were reduced compared to the control group. The difference between the two groups was statistically significant (P< 0.05). The incidence of adverse reactions was 1.74% for TQRP and 3.54% for DSP. CONCLUSION: TQRP is effective and safe in the treatment of CSR.

The mechanism and experimental verification of Ixeris sonchifolia promoting apoptosis of hepatocellular carcinoma based on network pharmacology: Ixeris sonchifolia Induces Hepatocellular Carcinoma Apoptosis via the PI3K/AKT Pathway.

ETHNOPHARMACOLOGICAL RELEVANCE: Ixeris sonchifolia alias Kudiezi, it was named Ixeris sonchifolia (Bunge) Hance, a synonym for Crepidiastrum sonchifolium (Bunge) Pak & Kawano in the https://www.iplant.cn/. And it was first published in J. Linn. Soc., Bot. 13: 108 (1873), which was named Ixeris sonchifolia (Maxim.) Hance in the MPNS (http://mpns.kew.org). As a widely distributed medicinal and edible wild plant, it possesses unique bitter-cold characteristics and constituents with various pharmacological activities. Its main antitumor substances, same as artemisinin and paclitaxel, are classified as terpenoids and have become research foci in recent years. However, its specific biological activity and role in antitumor treatment remain largely unclear. AIM OF THE STUDY: This study aimed to elucidate the molecular targets and potential mechanisms of hepatocellular carcinoma apoptosis induced by Ixeris sonchifolia. MATERIALS AND METHODS: We used network pharmacology methods to analyze and screen the active ingredients and possible underlying mechanisms of Ixeris sonchifolia in treating liver cancer and employed integrative time- and dose-dependent toxicity, transcriptomics, and molecular biology approaches to comprehensively verify the function of Ixeris sonchifolia extract (IsE) in human hepatoblastoma cell (HepG2) apoptosis and its potential mechanism. RESULTS: A total of 169 common targets were screened by network pharmacology, and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analysis showed that IsE inhibited HepG2 cell activity in a time- and dose-dependent manner. Western blot analysis confirmed that IsE promoted HepG2 cell apoptosis by inhibiting the PI3K/AKT signaling pathway and that the PI3K/AKT inhibitor LY294002 also substantially enhanced IsE-induced apoptosis. The PI3K/AKT signaling pathway exhibited significant differences compared to that in the control group. CONCLUSION: Combining network pharmacology with experimental verification, IsE inhibited mitochondrial function and the PI3K/AKT pathway while inducing hepatoma cell apoptosis. IsE may have promising potential for liver cancer treatment and chemoprevention.

Electroacupuncture for relieving itching in atopic eczema: study protocol for a multicenter, randomized, sham-controlled trial.

Background: Atopic eczema (AE) is a common atopic inflammatory skin disease affecting 2.1-4.9% of the population in different countries. Pruritus, one of the most burdensome symptoms, is often underestimated for the problems it can cause, creating a vicious loop of itching, scratching, and lichenification. Therefore, further research into practical and safe treatments that relieve itchy symptoms and enhance skin protection is key to overcoming AE. Acupuncture, with or without electrical stimulation, is one of the most commonly used therapeutic measures to treat AE. This trial aimed to objectively evaluate the efficacy and safety of the electroacupuncture (EA) antipruritic technique in AE pruritus and obtain high-level clinical evidence for the popularization and application of EA for AE. Methods and analysis: This multicenter, single-blinded, randomized controlled trial is planned to transpire from April 15, 2023, to June 30, 2025. We will recruit 132 participants with AE (44 per group). Participants will be assigned randomly to three equal-sized groups: EA, sham electroacupuncture, and sham acupuncture. Treatment will be administered three times a week during the 2-week intervention phase. The primary outcome measure is the Visual Analog Scale, with a numeric rating scale to evaluate pruritus. Secondary outcome measures include the Eczema Area and Severity Index and Dermatology Life Quality Index. Other outcome measures include physical examination, serum IgE, and safety evaluation. The number, nature, and severity of adverse events will be carefully recorded. Trial registration: ClinicalTrials.gov, 22Y11922200. Registered 3 September 2022, https://register.clinicaltrials.gov.
