OBJECTIVE To re-evaluate the use of systematic evaluation/meta-analysis of anti-VEGF drugs in the treatment of diabetic macular oedema （DME）， aiming to provide evidence-based support for the clinical application of this medication. METHODS A comprehensive search was conducted across a range of databases， including CNKI， Wanfang data， VIP， CBM， PubMed， Web of Science， Embase， and Cochrane Library. The objective was to identify systematic evaluation/meta-analysis of anti- VEGF drugs for DME， with search time from the inception of the databases to March 2024. The report quality， methodological quality， and evidence quality were assessed by using PRISMA2020 statement， AMSTAR2 scale and GRADE tool. A comprehensive analysis of systematic evaluation/meta-analysis results was also conducted. RESULTS A total of 22 articles were included. According to the PRISMA2020 statement evaluation， 13 studies provided relatively complete information （≥21 points）， while 9 studies had information deficiencies （18-＜21 points）. The AMSTAR 2 scale evaluation revealed that 21 studies had very low methodological quality， and one study had low methodological quality. The GRADE tool evaluation showed that out of 89 outcome indicators， 28（ 31.46%） were classified as high-quality evidence， 34（ 38.20%） as moderate-quality evidence， 24（ 26.97%） as low- quality evidence， and 3 （3.37%） as very low-quality evidence. The comprehensive quality analysis results demonstrated that， compared with laser photocoagulation， anti-VEGF drugs significantly enhanced the improvement in best-corrected visual acuity （BCVA）， as well as significant change in retinal thickness at 1 and 6 months， and 1 and 2 years post-treatment， and also in BCVA and retinal thickness at 1， 3， and 6 months post-treatment （P＜0.05）. Compared with placebo， patients treated with anti-VEGF drugs showed significant improvement in BCVA after 1 year of treatment （P＜0.05）. However， when compared with corticosteroid drugs， patients treated with anti-VEGF drugs exhibited a significant increase in retinal thickness after 6 months of treatment （P＜0.05）. Compared with corticosteroid drugs， the incidence of adverse events related to the eyes， cataract formation and intraocular pressure were significantly decreased in patients treated with anti-VEGF drugs （P＜0.05）. Compared with laser photocoagulation， the incidence of ocular adverse events was significantly decreased in patients treated with anti-VEGF drugs， while the incidence of fatal adverse events was significantly increased （P＜0.05）. CONCLUSIONS Anti-VEGF therapy for DME may possess certain advantages in terms of efficacy and safety， but it is associated with a higher risk of fatal adverse events； the evidence included in systematic reviews/meta-analyses is of moderate to high quality.

AIM: To explore the current status, research hotspots, and trends of global uveitis research to provide a theoretical basis and references for researchers in the field of uveitis, and promote further development in this area.METHODS: Relevant literatures on uveitis were retrieved from the China National Knowledge Infrastructure(CNKI)database, Wanfang database, and Web of Science core collection database since their establishment until 24 August 2023. The country/publishing institutions, research authors, high-frequency keywords, and burst keywords were visual analyzed by using software such as GraphPad Prism 9, CiteSpace 6.2. R2, and VOSviewer.RESULTS: Research teams for uveitis have been formed in various countries globally. The top three countries in terms of publications are the United States of America(7 585 papers), the United Kingdom(2 412 papers)and Germany(1 679 papers). The top three foreign institutions in terms of publications are Harvard University, Oregon Health & Science University, and Moorfields Eye Hospital, while the top three domestic institutions are Affiliated Eye Hospital of Shandong University of Traditional Chinese Medicine, Chongqing Medical University, and Zhongshan Ophthalmic Center, Sun Yat-sen University. The analysis of high-frequency keywords and burst keywords in Chinese and English shows that research hotspots mainly focus on exploring pathogenesis and different treatment methods for uveitis. The research hotspots related to uveitis treatment are transitioning to molecular biology-related research topics, such as molecular biological signaling pathways(NF-κB signaling pathway with a strength value of 22.89), biological agents(adalimumab with a strength value of 32.21), and tumor necrosis factor(with a strength value of 48.44). Related research is also expanding to basic experiments on relevant rats.CONCLUSIONS: In recent years, the research hotspots and trends of global uveitis mainly focus on precise diagnosis, pathogenesis, and more effective treatment methods. It is important for more scholars to dedicate themselves to uveitis-related research in the future to make breakthroughs and progress in the field. More large-scale and multicenter clinical studies on uveitis can provide high-quality research evidence.

Objectives: . Branchio-oto syndrome (BOS) primarily manifests as hearing loss, preauricular pits, and branchial defects. EYA1 is the most common pathogenic gene, and splicing mutations account for a substantial proportion of cases. However, few studies have addressed the structural changes in the protein caused by splicing mutations and potential pathogenic factors, and several studies have shown that middle-ear surgery has limited effectiveness in improving hearing in these patients. BOS has also been relatively infrequently reported in the Chinese population. This study explored the genetic etiology in the family of a proband with BOS and provided clinical treatment to improve the patient’s hearing. Methods: . We collected detailed clinical features and peripheral blood samples from the patients and unaffected individuals within the family. Pathogenic mutations were identified by whole-exome sequencing and cosegregation analysis and classified according to the American College of Medical Genetics and Genomics guidelines. Alternative splicing was verified through a minigene assay. The predicted three-dimensional protein structure and biochemical experiments were used to investigate the pathogenicity of the mutation. The proband underwent middle-ear surgery and was followed up at 1 month and 6 months postoperatively to monitor auditory improvement. Results: . A novel heterozygous EYA1 splicing variant (c.1050+4 A>C) was identified and classified as pathogenic (PVS1(RNA), PM2, PP1). Skipping of exon 11 of the EYA1 pre-mRNA was confirmed using a minigene assay. This mutation may impair EYA1-SIX1 interactions, as shown by an immunoprecipitation assay. The EYA1-Mut protein exhibited cellular mislocalization and decreased protein expression in cytological experiments. Middle-ear surgery significantly improved hearing loss caused by bone-conduction abnormalities in the proband. Conclusion . We reported a novel splicing variant of EYA1 in a Chinese family with BOS and revealed the potential molecular pathogenic mechanism. The significant hearing improvement observed in the proband after middle-ear surgery provides a reference for auditory rehabilitation in similar patients.

Objective To explore the effect of endoscopic hemostasis combined with octreotide on hemodynamics and clinical outcome of patients with acute upper gastrointestinal bleeding.Methods From January 2019 to June 2022,80 patients with acute upper gastrointestinal bleeding in Xinyu Yinhe Hospital of Jiangxi Province,and according to random number table method,40 cases each in the control group and 40 cases in the observation group.The control group was treated with conventional endoscopic,while the observation group was treated with octreotide on this basis.The clinical efficacy,high sensitivity C-reactive protein(hs-CRP),cortisol(Cor)levels and hemodynamic changes[cardiac output(CO),heart rate(HR),mean arterial pressure(MAP)]were compared between the two groups.Results The total effective rate of the observation group was significantly higher(P<0.05).After treatment,hs-CRP and Cor levels in 2 groups were lower than before,and hs-CRP and Cor levels in observation group were significantly lower(P<0.05).After treatment,the levels of CO,HR and MAP in the two groups were decreased,and the levels of CO,HR and MAP in the observation group were significantly lower(P<0.05).Conclusion Endoscopic hemostasis combined with octreotide can promote the hemodynamic indexes of patients with acute upper gastrointestinal bleeding to return to normal,improve the levels of hs-CRP and Cor,and improve clinical efficacy.

METHODS:In retrospective study,clinical information of 88 VD patients selected from neurology department of our hospital during May 2013-Feb. 2015 were divided into observation group and control group according to therapy plan,with 44 cas-es in each group. Both groups received conventional treatments such as controlling blood pressure and blood glucose,anticoagulation. Control group was additionally given Rosuvastatin calcium tablets orally 20 mg,at bedtime;observation group was additionally given Probucol tablet 0.5 g,bid,after meal,on the basis of control group. Both groups received treatment for consecutive 3 months. MMSE and ADL score were compared between 2 groups before and after treatment as well as the levels of TC,TG,LDL-C,HDL-C,CRP, TNF-α,IL-6,IL-1β,SOD and MDA. The occurrence of ADR was also observed. RESULTS:Before treatment,there was no statisti-cal significance in above indexes between 2 groups(P>0.05). Compared to before treatment,MMSE and ALD score,serum SOD lev-el of 2 groups were increased significantly,while serum levels of TC,TG,LDL-C,CRP,TNF-α,IL-6,IL-1βand MDA were de-creased significantly after treatment,with statistical significance(P<0.05). Above indexes of observation group were significantly bet-ter than those of control group,with statistical significance(P<0.05). There was no statistical significance in HDL-C level between 2 groups before and after treatment (P>0.05). There was no statistical significance in the incidence of ADR between 2 groups(P>0.05).CONCLUSIONS:Probucol combined with rosuvastatin is better than rosuvastatin alone in reducing blood lipid,serum inflamma-tory factors and oxidant stress indexes levels,improving cognitive function and quality of life with good safety.

To study the role and molecular mechanism of epigallocatechin gallate (EGCG) in reversing drug-resistance to 5-fluorouracil (5-FU) in gastric cancer drug-resistant cell line SGC-7901/5-FU.

METHODSDrug-resistance gastric cancer cell line (SGC-7901/5-FU) was established by high doses of repeated impact joint drug concentration increment methods. The cell viability of the parent cell line and the drug-resistance cell line were determined by standard MTT assay. Cell survival rate of drug-resistance was calculated by the formula [(Aof the treatment group / Aof the control group) × 100%]. Cell half inhibitory concentration (IC) and resistance index (RI) were calculated by the Graphpad prime 6.0 software(RI=ICvalue of drug-resistance cells / ICvalue of parent cells). The apoptosis rate of SGC-7901/5-FU cells was quantified by flow cytometry after staining with annexin-V and PI. Western blot was used to detect the protein expression of drug-resistance-related proteins (ABCG2, P-gp, MDR-1 and GST-π) and apoptosis-related proteins (PARP, Survivin, Bax and bcl-2).

RESULTSICvalue was significantly increased in drug-resistant cells compared with parental cells [(64.7±3.9) mg/L and (4.1±0.3) mg/L, respectively, t=26.46, P=0.000], and the RI was 15.6. Proliferation activity in the drug-resistant cells was higher than that in parental cells at different 5-FU concentrations (all P<0.05). In drug-resistant cells, the ICvalue of 5-FU combined with EGCG group obviously decreased compared with 5-FU group [(7.3±0.1) mg/L and (63.1±1.4) mg/L respectively, t=40.84, P=0.000], and the RI was 0.12. Proliferation activity in drug-resistant cells was significantly decreased after EGCG treatment at different 5-FU concentrations (all P<0.05). Cell apoptosis rates in control group, 5-FU group, EGCG group and 5-FU combined with EGCG group were (3.0±1.0)%, (7.0±1.3)%, (6.0±1.2)% and (18.0±1.4)%, while apoptosis rate in 5-FU combined with EGCG group was significantly higher than those of other 3 groups(F=129.5, P=0.000). Western blot revealed that after EGCG treatment, the expression levels of drug-resistance-related proteins (ABCG2, P-gp, MDR-1 and GST-π) in the drug-resistant cell line SGC-7901/5-FU decreased significantly; the expression levels of apoptosis marker protein PARP and pro-apoptotic protein Bax increased significantly; and the expression levels of anti-apoptotic protein Survivin and Bcl-2 decreased significantly (all P<0.05).

CONCLUSIONEGCG can reduce the resistance of gastric cancer resistant cell line SGC-7901/5-FU, whose role may be via the inhibition of the expression of drug-resistance-related proteins, and the elevation of the protein expression ratio of PARP/Survivin and Bax/Bcl-2.
