Objective:To analyze the changes of DNA methylation in peripheral blood mononuclear cells (PBMC) of patients with hepatocellular carcinoma (HCC) and to evaluate the clinical value of a combined model based on FSIP1 gene methylation on the early diagnosis of HCC.Methods:This is a case-control study. From May 2023 to September 2024, 183 HCC patients and 155 healthy controls were collected in Qilu Hospital of Shandong University. The selected study subjects were divided into three cohorts: 14 HCC patients and 39 healthy controls formed the discovery cohort, a screening cohort consisted of 36 HCC patients and 39 healthy controls, 133 HCC patients and 77 healthy controls were included in the model construction cohort. 935k methylation chip analysis was used to identify specific differentially methylated sites in peripheral blood PBMC of the discovery cohort. The absolute value of the average methylation level difference between HCC group and healthy control group (|Δβ|) and P value were calculated. Then targeted bisulfite sequencing was used to verify the differentially methylated sites in the screening cohort. Finally, based on MethylTarget methylation sequencing technology, differential methylation sites were further verified in model construction cohort (divided into training set and validation set, training set consisted of 99 HCC patients and 57 healthy controls; validation set consisted of 34 HCC patients and 20 healthy controls). HCC early diagnosis model was constructed by random forest algorithm combined with clinical parameters and the diagnostic performance of the model was evaluated by receiver operating characteristic (ROC) curve in the validation set. Results:The total of 7 249 differentially methylated sites between HCC patients and healthy controls in discovery cohort were selected under the rule of |Δβ|≥0.06 and P<0.01. Among them, the cg02155073 site located on FSIP1 was hypermethylated in PBMC of HCC patients in the screening cohort and model cohort ( P<0.001). The AUC of HCC early diagnosis model (FmAP) based on FSIPI in the validation set was 0.967 (95% CI 0.924-1.000); sensitivity was 88%, specificity was 95%. The model had good diagnostic efficacy for patients with early HCC, stage Ⅰ-Ⅱ HCC AUC was 0.958 (95% CI 0.898-1.000). The FmAP model also had diagnostic value for tumor size <2 cm HCC and AFP negative HCC, with AUC of 0.955 (95% CI 0.898-1.000) and 0.964 (95% CI 0.934-0.994).The sensitivity were 92% and 93% and specificity both were 84%. Conclusion:The FmAP model based on FSIP1 gene methylation has good clinical value for the early diagnosis of hepatocellular carcinoma.

ObjectiveTo observe the effect of Coptidis Rhizoma and Ophiopogonis Radix on renal tissue injury and epidermal growth factor receptor (EGFR)/phosphatidylinositol 3-kinase (PI3K)/protein kinase B (Akt) signaling pathway in rats with diabetic nephropathy (DN) and explore its possible mechanism of delaying DN. MethodThirty-six male Wistar rats were randomly divided into a normal group (6 rats) and a model group (30 rats). The model group was fed with a high-fat and high-sugar diet combined with streptozotocin (STZ) to establish a rat model of type 2 diabetes. After the successful preparation of the model, the rats were randomly divided into the model group, low, medium, and high dose groups of Coptidis Rhizoma and Ophiopogonis Radix (100, 200, 400 mg·kg-1), and metformin group (200 mg·kg-1). After administration, the levels of fasting blood glucose (FBG), 24 h urine protein (24 h-UTP), creatinine (SCr), urea nitrogen (BUN), and uric acid (UA) were detected. Hematoxylin-eosin (HE) staining and Masson staining were used to observe the pathological changes of renal tissue in rats. Western blot and Real-time fluorescence quantitative polymerase chain reaction (Real-time PCR) were used to detect the related protein expression of EGFR, PI3K, and Akt and their mRNA expression levels in the renal tissue of rats in each group. ResultsCompared with the normal group, the levels of FBG, SCr, BUN, UA, 24 h-UTP, and kidney index in the model group were significantly increased (P<0.01), most renal tubular epithelial cells were necrotic, and the content of collagen in glomeruli was significantly increased (P<0.01). Compared with the model group, the above indexes of rats in each administration group were improved to varying degrees. The FBG, SCr, BUN, UA, 24 h-UTP, and kidney index of rats in each dose group and metformin group were significantly decreased (P<0.01, P<0.05). The necrosis degree of renal tubular epithelial cells was reduced, and the fibrosis area was decreased (P<0.01). There related protein and mRNA expressions of EGFR, PI3K, and Akt were significantly increased (P<0.05, P<0.01). ConclusionCoptidis Rhizoma and Ophiopogonis Radix can alleviate renal tissue injury in rats with DN, and their mechanism may be related to the regulation of the EGFR/PI3K/Akt signaling pathway.

AIM: To evaluate the efficacy of 0.01% hypochlorous acid as a conjunctival sac disinfectant before cataract phacoemulsification and its impact on the ocular surface.METHODS: Randomized controlled clinical trial. A total of 285 patients who were scheduled for cataract phacoemulsification surgery were randomly divided into the hypochlorous acid group and the povidone iodine group. Before and after disinfection, conjunctival sac swabs were taken, and bacterial culture and colony-forming units(CFUs)testing were performed using blood agar and chocolate agar media, respectively. All patients were evaluated for ocular symptom scores and pain severity scores 2 h, 1 d, and 1 wk after disinfection, and underwent corneal fluorescein staining, eye redness index, tear meniscus height, and noninvasive breakup time(NIBUT)examination. The incidence of endophthalmitis after surgery was recorded.RESULTS: Conjunctival sac disinfection with 0.01% hypochlorous acid significantly reduced the rate of positive bacterial cultures and colony-forming ability of the conjunctival sac, with statistically significant differences compared with the pre-disinfection period(both P<0.01), and the disinfecting ability of hypochlorous acid was comparable to that of povidone-iodine(χ2=0.811, P=0.368). The scores of ocular symptoms and pain severity in the hypochlorous acid group were significantly lower than those in the povidone-iodine group(both P<0.01). The corneal fluorescein staining and eye redness index in the hypochlorous acid group were significantly lower than those in the povidone-iodine group(all P<0.01). No endophthalmitis occurred in either group of patients. CONCLUSION: As a conjunctival sac disinfectant, 0.01% hypochlorous acid is safe and effective, with minimal discomfort and damage to the ocular surface in patients.

AIM:To establish a model of meibomian gland dysfunction in rats induced by eyeliner tattoo and investigate its potential mechanisms.METHODS:A total of 40 SD rats were selected, with 30 randomly chosen to have eyeliner tattoo applied their right eyes and designated as the eyeliner group. The remaining 10 rats were not given any treatment and served as the normal group. The corneal morphology of both groups was observed using a slit lamp at 1, 2, and 4 wk after establishment, and the tear film break-up time(BUT), Schirmer I test(SIt), corneal fluorescein staining score, and corneal irregularity score were calculated. The corneal Placido rings were examined using an ocular surface analyzer, and the corneal tissue structures of both groups were observed under a confocal microscope. After 4 wk and completion of clinical indicator recording, the eyeballs and upper and lower eyelid tissues were taken for pathological examination. The meibomian gland structures were observed through HE staining, the conjunctival goblet cells were observed using PAS staining, and the lipid droplets were observed with ORO staining.RESULTS:The slit lamp examination results showed that the eyeliner group rats exhibited in situ black pigmentation in the eyelids, with no eyelid deformation or scarring. The corneal epithelium was rough, with positive fluorescein staining, presenting as spotty staining that worsened over time. Compared with the normal group, the BUT was significantly shortened, tear secretion volume was significantly decreased, and the corneal fluorescein staining score and corneal irregularity score were significantly increased at 1, 2, and 4 wk after modeling in the eyeliner group(all P<0.01). The corneal confocal microscopy results showed a decrease in corneal epithelial cells in the eyeliner group, with the appearance of abnormally bright cells, and inflammatory cell infiltration visible in the stromal layer. The ORO staining results revealed a decrease in lipid droplets in the eyeliner group, showing a downward trend with increasing observation time. The HE staining results showed that pigment blocked the meibomian gland openings in the eyeliner group, and the density of meibomian gland acini showed a downward trend over time. The PAS staining results showed a decreasing trend in the number of PAS-positive cells in the eyeliner group.CONCLUSION:Eyeliner tattoo can induce meibomian gland dysfunction, and the blockage of meibomian gland openings caused by the pigment particles used may be an important cause of meibomian gland dysfunction.
