In order to investigate the efficiency of a new quantitative head-band formed ocular compressor to reduce intraocular pressure (IOP), ocular compression by this new reducer with 40 mmHg for 10 min was performed on 87 cataractous eyes of 78 cases. The changes of IOP (87 eyes) and anterior chamber depth (ACD) were observed. There was a significant decrease of IOP and increase of ACD within 30 min after decompression (P < 0.001). The mean decrease of IOP was 5.62 +/- 2.41 mmHg and the mean increase of ACD was 0.18 +/- 0.09 mm within 5 min after decompression. The IOP 5 min after decompression had no significant difference with that 10 min after decompression (P > 0.05). IOP below 10 mmHg could last for about 15 min. This apparatus had been successfully applied to 80 eyes for extracapsular cataract extraction. It was suggested that this device had the advantages of safety, accurate quantification, reliable effect, casually adjusting pressure according to various demands and time-saving.

The clinical manifestation and characteristics of CT image of 117 cases of orbital tumors in our hospital were investigated. The hemangioma had the highest incidence, and the less common tumors were, in sequence of incidence, pseudotumor, dermoid cysts, neurilemmoma, polymorphous adenoma and meningioma. The sensitivity in diagnosis of orbital tumor by CT was 93.3%. The coincidence of CT histological diagnosis with pathology were 83.3 %, 82.6 % and 71.4% for dermoid.cysts, hemangioma, and pseudotumor respectively, but the general coincidence of CT histological diagnosis with pathology was only 67.8 %. When CT was combined with ultrasound, cytological examination and clinical manifestations, the accuracy of histological diagnosis could be improved to 83.3 %.

Objective:To conduct a visual analysis of the related literature on hydrogel materials that promote wound healing, and to explore the research status, hotspots and future development trends in this field, in order to provide a reference for future research and development.Methods:The Web of Science Core Collection database was searched to obtain relevant literature on the promotion of wound healing by hydrogel materials from January 1, 2010 to October 1, 2023. Bibliometrics method were used to integrate the year, author, publication, number of national and institutional publications, cumulative citation and co-citation frequency and key words of the included literatures. VOSviewer 1.6.19 and CiteSpace 6.2.R4 were used for the literature’s visualization analysis and mapping.Results:A total of 3 863 literatures were included, involving 18 921 authors, and the number of publications in this field showed a significant increasing trend from 2010 to 2023. Zhao YJ, the researcher with the most publications, published 38 articles. There were 557 journals that had collected relevant literatures, and the International Journal of Biological Macromolecules had published the most literature, with a total of 286 publications. A total of 92 countries and 3 307 institutions had conducted research in related fields, with China publishing the most papers. Research institutions mainly come from China and the United States. The literature with the highest cumulative citation frequency was "Alginate: properties and biomedical applications", which reached 4 737 times. The highest cumulative co-citation frequency was the literature published by Qu J, et al in 2018, with a total of 404 times. Keyword co-occurrence, clustering, time line and emergence analysis showed that the early research in this field mainly focused on the process of wound healing and the cellular mechanism at the molecular level, and later gradually focused on the development of precise controlled release function of nanoparticles and antibacterial compounds in hydrogel scaffolds. Conclusion:Research on the application of hydrogel materials in wound healing is attracting increasing international attention. According to the changes of hot words, the future research trend in this field is to develop intelligent hydrogels with regulatory capabilities, wound monitoring, controlled drug delivery and diversified functions.

Objective:To conduct a network meta-analysis comparing the efficacy and safety of various drug injections for treating keloids.Methods:The search terms of "triamcinolone acetonide, 5-fluorouracil, verapamil, botulinum toxin, platelet rich plasma, keloid, scar, drug injection" were retrieved in PubMed, Embase, Web of Science, CNKI and Wanfang database to obtain the publicly published randomized controlled trials comparing single or combined drug injection for treating keloid from January 2010 to February 2023. The outcome index was the effective proportion of treatment, incidence proportion of adverse reactions, and recurrence proportion. NoteExpress, RevMan 5.4, and Stata 16.0 statistical software were utilized to perform a network meta-analysis of eligible studies that met the inclusion and exclusion criteria.Results:A total of 1 679 patients were enrolled in 21 studies that evaluated nine treatment modalities: triamcinolone (TAC), 5-fluorouracil (5-FU), botulinum toxin type A (BTA), platelet-rich plasma (PRP), Verapamil, BTA+ 5-FU, TAC+ 5-FU, TAC+ BTA, and TAC+ PRP. The network diagram revealed that there were 36 pairwise comparisons among the 9 treatment measures, with direct comparisons in 13 of them. The funnel plot demonstrated a symmetrical distribution of effect size points, and both Beggs test and Eggers test yielded P values greater than 0.05, indicating a low likelihood of publication bias. Nine treatment measures formed five closed loops with good consistency. The result of the network meta-analysis indicated that BTA+ 5-FU was more effective than TAC, 5-FU, or PRP alone; TAC+ 5-FU was more effective than TAC, 5-FU, or PRP alone; TAC+ BTA was more effective than TAC, 5-FU, BTA, or PRP alone; Verapamil was more effective than 5-FU and BTA was more effective than 5-FU. All result were found to be statistically significant ( P<0.05). A surface under the cumulative ranking area (SUCRA) map was generated, displaying the efficacy ranking and corresponding SUCRA values for each treatment: BTA+ 5-FU (85.6%)>TAC+ 5-FU (84.8%)>BTA+ TAC (76.7%)>Verapamil (48.9%)>BTA (45.0%)>TAC+ PRP (43.8%)>PRP (32.1%)>TAC (24.7%)>5-FU(8.3%). In terms of recurrence rate, the incidence of recurrence was higher with 5-FU compared to BTA or TAC+ 5-FU, and the incidence of recurrence was higher with TAC compared to TAC+ 5-FU; these differences were statistically significant ( P<0.05). A SUCRA map was generated with the ranking and SUCRA value for each treatment as follows: 5-FU (80.4%)>TAC (73.5%)>Verapamil (65.7%)>TAC+ BTA (52.5%)>PRP (34.8%)>BTA+ 5-FU (33.7%)>TAC+ 5-FU (30.2%)>BTA (29.3%). The qualitative analysis revealed a significantly lower incidence of systemic and local adverse reactions following combined drug injection compared to single drug injection. Conclusion:In the treatment of keloids using drug injection, combination therapy utilizing multiple drugs has demonstrated superior efficacy, lower recurrence rates, and fewer adverse reactions in comparison to single-drug therapy. Notably, the utilization of BAT, 5-FU, and TAC in combination may yield the most favorable outcomes.
