Phacoemulsification represents the mainstream, efficient, and safe surgical modality for cataract treatment, and continuous technological advances have further improved the safety profile of this procedure in ordinary patients. However, patients with high myopia feature inherent anatomical abnormalities of the eyeball, leading to a fundamental incompatibility with conventional phacoemulsification protocols. Such patients face a markedly elevated risk of both anterior and posterior segment perioperative complications, posing a persistent clinical challenge in cataract surgery. Focusing on the unique ocular anatomical characteristics associated with high myopia, this review systematically summarizes the distinct traumatic effects and pathological impacts of phacoemulsification on the anterior and posterior ocular segments of affected patients. Moving beyond generalized discussions of routine cataract management, it consolidates clinical evidence specific to this special-population patients, aiming to provide refined references for perioperative risk prevention and control in cataract patients complicated with high myopia.

Objective:To explore the expressions of long noncoding RNA (lncRNA) homeobox A11 antisense RNA (HOXA11-AS) and lymphoid enhancer-binding factor 1 antisense RNA 1 (LEF1-AS1) in hypopharyngeal carcinoma tissues and their relationships with prognosis.Methods:Prospectively, 80 patients with hypopharyngeal carcinoma who were treated in Handan Central Hospital from February 2019 to February 2021 were selected. The hypopharyngeal carcinoma tissues resected surgically and the adjacent normal tissues (more than 2 cm away from the edge of the cancer tissue) were obtained. The expressions of HOXA11-AS and LEF1-AS1 were detected by real-time fluorescence quantitative polymerase chain reaction (RT-qPCR). The expressions of HOXA11-AS and LEF1-AS1 in hypopharyngeal carcinoma tissues and adjacent normal tissues were compared. The relationships between their expressions and clinicopathological features were analyzed. The Kaplan-Meier method was used to analyze the relationships between high/low expressions of HOXA11-AS and LEF1-AS1 and the prognosis of patients with hypopharyngeal carcinoma.Results:The expressions of HOXA11-AS and LEF1-AS1 in hypopharyngeal carcinoma tissues were higher than those in adjacent normal tissues (all P<0.05). The expressions of HOXA11-AS and LEF1-AS1 in hypopharyngeal carcinoma tissues were related to tumor node metastasis (TNM) stage, degree of differentiation, and lymph node metastasis (all P<0.05). The 3-year overall survival rates of patients with high expressions of HOXA11-AS and LEF1-AS1 in hypopharyngeal carcinoma tissues were lower than those of patients with low expressions (all P<0.05). Conclusions:The expressions of HOXA11-AS and LEF1-AS1 are increased in hypopharyngeal carcinoma tissues, which are related to poor prognosis of patients with hypopharyngeal carcinoma.

OBJECTIVE To mine the adverse drug events （ADE） signals for gilteritinib， and provide a reference for safe drug use in clinic. METHODS ADE reports with gilteritinib as the primary suspected drug were extracted from the FDA Adverse Event Reporting System （FAERS） database from February 1st， 2018 to December 31st， 2023. Reporting odds ratio （ROR） and proportional reporting ratio （PRR） were applied to detect the risk signals from the data in the FAERS database. The classification and statistics of collected signal data were conducted by using the preferred term （PT） and systemic organ class （SOC） in ADE terminology set of the Medical Dictionary for Regulatory Activities （24.1 edition）. RESULTS Totally， 2 755 gilteritinib-related ADE reports were collected from the database， involving 676 ADE signals （95 positive signals）， 313 PTs and 25 SOCs. Among them， nine signals were not recorded in the package insert. The top 5 PTs consisted of abnormal liver function， decreased platelet count， febrile neutropenia， pneumonia and myelosuppression. The top 6 SOCs for positive signal counts were examinations， general disorders and administration site conditions， respiratory， thoracic and mediastinal disorders， infections and infestations， heart organ disorders， and nervous system disorders. ADEs not recorded in the drug package insert included pneumonia， myelosuppression， decreased blood cell count， sepsis， hemorrhage， infection （not specifically referred to）， septic shock， respiratory failure， and aspergillosis. CONCLUSIONS In addition to paying attention to common ADEs such as liver dysfunction and thrombocytopenia， it is necessary to monitor ADEs with strong signals that are not mentioned in the drug instructions when using gefitinib， such as pneumonia， bone marrow suppression， cytopenia， sepsis， bleeding， infection （not specifically referred to）， septic shock， respiratory failure， Aspergillus infection， elevated serum creatinine and interstitial lung disease.

AIM: To evaluate the binocular visual function in high myopia patients after the implantation of implantable collamer lens(ICL)V4c.METHODS: A total of 35 cases(70 eyes)that received binocular ICL implantation at our hospital from May 2019 to May 2021 were enrolled in this prospective study. Binocular full-range visual acuity, contrast sensitivity, stereopsis, mesopic vision and glare sensitivity, and monocular wavefront and the quality of vision questionnaire were assessed before the surgery and at 1 mo postoperatively.RESULTS: At 1 mo postoperatively, 35 cases(100%)had binocular uncorrected distance visual acuity(UDVA)≤0.00(LogMAR), 16 cases(46%)had binocular UDVA≥preoperative corrected distance visual acuity(CDVA). Binocular UDVA and uncorrected intermediate visual acuity(UIVA,80 cm)were improved compared to preoperative CDVA and distance-corrected intermediate visual acuity(DCIVA,80 cm)(all P<0.05).While there were no differences in the binocular postoperative UIVA(60 cm)and preoperative DCIVA(60 cm),and uncorrected near visual acuity(UNVA,40 cm)and preoperative distance-corrected near visual acuity(DCNVA,40 cm)(all P>0.05). The binocular contrast sensitivity was significantly improved postoperatively(P=0.001), and the postoperative binocular mesopic vision, glare sensitivity(no glare/glare)and binocular stereopsis(5 m/40 cm)had no differences(all P>0.05). The postoperative total higher-order aberration, trefoil aberration, coma and spherical aberration were increased, besides the median of total coma in the right eye with a pupil diameter of 3.0 mm was decreased after surgery. The mean total score of quality of vision questionnaire was significantly increased from 54.87 preoperatively to 80.92 after implantation(P<0.05), with high satisfaction and no obvious visual disturbance in patients.CONCLUSION: Although the monocular high-order aberrations increased in the early stage after ICL V4c binocular implantation in patients with high myopia, the binocular visual function was improved.

BACKGROUND: Osteoarthritis (OA), a degenerative joint disorder, is a major reason of disability in adults. Accumulating evidences have proved that bone marrow mesenchymal stem cells (BMSCs)-carried exosomes play a significant therapeutic effect on OA. However, the precise regulatory network remains unknown. METHODS: OA and normal cartilage samples were acquired from patients, and chondrocytes were exposed to IL-1b to conduct a cellular OA model. Exosomes prepared from BMSCs were identified using nanoparticle tracking analysis (NTA) and transmission electron microscopy (TEM). Cell viability was determined with CCK-8 assay. Inflammatory injury was assessed by LDH and inflammatory factors (TNF-a and IL-6) using corresponding ELISA kits, respectively. Ferroptosis was evaluated by GSH, MDA and iron levels using corresponding kits, and ROS level with DCFH-DA. The expressions of genes/proteins were determined with RT-qPCR/western bolt. RNA immunoprecipitation and luciferase activity assay were conducted for testing the interactions of small nucleolar RNA host gene 7 (SNHG7)/ferroptosis suppressor protein 1 (FSP1) and miR-485-5p. RESULTS: The expressions of SNHG7 and FSP1 were both reduced in IL-1b-induced chondrocytes and OA cartilage tissues, and there was a positive correlation between them in clinical level. Moreover, SNHG7 was enriched in BMSCsderived exosomes (BMSCs-Exos) and could be internalized by chondrocytes. Functional analysis illustrated that BMSCsExos administration repressed inflammatory injury, oxidative stress and ferroptosis in IL-1b-induced chondrocytes, while these changes were reinforced when SNHG7 was overexpressed in BMSCs-Exos. Notably, FSP1 silencing in chondrocytes abolished the beneficial effects mediated by exosomal SNHG7. CONCLUSIONS Exosomal SNHG7 released from BMSCs inhibited inflammation and ferroptosis in IL-1b-induced chondrocytes through miR-485-5p/FSP1 axis. This work suggested that BMSCs-derived exosomal SNHG7 would be a prospective target for OA treatment.

Objective:To explore the relationship between the expression of long chain non coding ribonucleic acid (LncRNA) small nucleolar RNA host gene 1 (LncRNA SNHG1) and microRNA (miR)-143-3p in nasopharyngeal squamous cell carcinoma (HSCC) tissue and clinical pathological features and prognosis.Methods:A prospective selection was made from 97 HSCC patients admitted to the Handan Central Hospital from March 2016 to March 2018. Surgical resection of HSCC tissue and normal mucosa tissue adjacent to cancer were taken, and real-time fluorescence quantitative polymerase chain reaction (qRT-PCR) was used to detect the expression of LncRNA SNHG1 and miR-143-3p. The patient′s survival status was followed up after leaving the hospital. We compared the differences in the expression of LncRNA SNlHG1 and miR-143-3p in HSCC tissues with different clinical pathological parameters, analyzed the correlation between LncRNA SNHG1 and miR-143-3p expression, and the relationship between LncRNA SNHG1 and miR-143-3p expression and the prognosis of HSCC patients.Results:The expression of LncRNA SNHG1 in HSCC tissue was higher than that in normal mucosa tissue adjacent to cancer ( P<0.05), and the expression of miR-143-3p was lower than that in normal mucosa tissue adjacent to cancer ( P<0.05). The expression of LncRNA SNHG1 in cancer tissues of HSCC patients with tumor node metastasis (TNM) stage Ⅲ, low to medium differentiation, and lymph node metastasis was higher than that of HSCC patients with TNM stage Ⅰ-Ⅱ, high differentiation, and no lymph node metastasis (all P<0.05), and the expression of miR-143-3p was lower than that of HSCC patients with TNM stage Ⅰ-Ⅱ, high differentiation, and no lymph node metastasis (all P<0.05). The expression of LncRNA SNHG1 in HSCC tissues is negatively correlated with the expression of miR-143-3p ( r=-0.522, P<0.05). The 5-year cumulative survival rate of HSCC patients with high expression of LncRNA SNHG1 was lower than that of HSCC patients with low expression of LncRNA SNHG1 ( P<0.05), and the 5-year cumulative survival rate of HSCC patients with low expression of miR-143-3p was lower than that of HSCC patients with high expression of miR-143-3p ( P<0.05). Multivariate Cox regression analysis showed that TNM stage Ⅲ and high expression of LncRNA SNHG1 were risk factors for poor prognosis in HSCC patients (all P<0.05), while high expression of miR-143-3p was a protective factor ( P<0.05). Conclusions:The expression of LncRNA SNHG1 is upregulated and miR-143-3p is downregulated in HSCC tissues, with a negative correlation between the two, which is related to the malignant pathological characteristics and poor prognosis of HSCC.
