Myopia has become a significant eye health problem, which is thought to result from the complex interactions of genetic and environmental factors. This review focuses on two types of hereditary retinal diseases caused by mutations in photoreceptor genes, including rod-cone cell dystrophy(retinitis pigmentosa)and cone dysfunction syndromes(achromatopsia, blue cone monochromatism and Bornholm eye disease). It systematically explores the intrinsic connection between these diseases and the myopia phenotype, and elaborates on the core mechanisms by which pathogenic genes such as RPGR and OPN1LW/OPN1MW, which cause defects in ciliary structure and protein transport and interfere with the visual signal pathway, jointly induce choroidal thinning and scleral remodeling, ultimately driving the elongation of axial length and the occurrence of myopia. By tracing the association of photoreceptor gene mutations with myopia, this article provides a new perspective for in-depth understanding of the genetic mechanism of myopia and is of great significance for the development of early risk warning and targeted intervention strategies.

OBJECTIVE To provide references for medical institutions’ outpatient pharmacies to increase the scanning rate, scanning efficiency and scanning accuracy of drug traceability codes.METHODS A total of 4 157 unscanned traceability code records from the first two‑week period of June 2025 were selected from the outpatient pharmacy of our hospital. Pareto chart was adopted to analyze the reasons for unscanned codes, and the Objective-Rules-Training-Check-Culture (ORTCC) model was utilized to carry out fine management. The traceability code scanning rate, pharmacists’ work efficiency (number of prescriptions dispensed per pharmacist per hour, number of drug boxes dispensed per pharmacist per hour), patients’ medication-waiting time and dispensing errors were compared among four periods: before scanning implementation (June 2024), before management intervention (June 2025), the first phase after management (September 2025), and the second phase after management (December 2025), so as to evaluate the management effects.RESULTS The traceability code scanning rates in the first phase and second phase after management were remarkably higher than those before management ( P <0.05), and the scanning rate in the second phase after management was obviously higher than that in the first phase after management ( P <0.05). Compared with the period before scanning implementation, the number of prescriptions dispensed per pharmacist per hour, the number of drug boxes dispensed per pharmacist per hour, decreased significantly and patients’ medication-waiting time prolonged markedly before management ( P <0.05). In the second phase after management, both the number of prescriptions dispensed per pharmacist per hour and the number of drug boxes dispensed per pharmacist per hour increased significantly, and patients’ medication-waiting time shortened greatly in contrast with the status before management ( P <0.05). Besides, no statistically significant differences were found in the number of drug boxes dispensed per pharmacist per hour and patients’ medication-waiting time between the second phase after management and the period before scanning implementation ( P >0.05).After the implementation of traceability-code scanning management, dispensing errors presented a gradually declining trend in each stage.CONCLUSIONS The fine management system for outpatient drug traceability codes constructed based on Pareto chart and ORTCC model can improve the traceability code scanning rate and pharmacists’ work efficiency of outpatient pharmacies, and reduce drug dispensing errors.

Objective:To evaluate the short-and medium-term therapeutic efficacy of shockwave balloon therapy for TASCⅡ C/D femoropopliteal artery atherosclerosis obliteration.Methods:This retrospective cohort study included 25 patients who received shockwave balloon therapy in five vascular centers from August 2022 to June 2023. All patients were diagnosed with TASC Ⅱ C/D femoropopliteal arteriosclerosis obliterans (13 cases of type C and 12 cases of type D), and underwent intravascular shock wave lithotripsy (IVL) to treat calcified lesions. The immediate effectiveness (residual stenosis<30% and no flow-limiting dissection), safety (whether there were adverse vascular events during the operation) and the rate of salvage stent implantation were recorded. The observation indexes of patients before operation, early postoperative period (immediately after operation or before discharge) and postoperative follow-up period (3, 6, 12 months after operation) were collected. The observation indexes included ankle-brachial index (ABI), Rutherford classification, and minimum lumen diameter (MLD). Repeated measures ANOVA was used to evaluate the changes of observation indexes in the early postoperative and follow-up stages compared with those before operation; Kaplan-Meier survival analysis was used to evaluate the one-stage patency rate at follow-up and the target lesion revascularization rate free from clinical drive.Results:The immediate effectiveness of surgery was 100% in all patients, with no vascular related adverse events occurred, and no remedial stent implantation was performed. The ABI, Rutherford grade and MLD of the patients in the early postoperative period and each follow-up stage were improved compared with those before operation, with statistically significant differences ( P<0.05). Kaplan-Meier survival analysis showed that the primary patency rate at 12 months after surgery was 0.78 (95% CI 0.64-0.84), and the revascularization rate of target lesions free from clinical drive was 0.87 (95% CI 0.85-0.95). Conclusion:Shockwave balloon therapy for complex calcified femoropopliteal artery lesions is safe and reliable, with satisfactory short-and medium-term efficacy.

Objective:To analyze the effect of long noncoding RNA (lncRNA) small nucleolar RNA host gene 16 (SNHG16) on the radiosensitivity of cervical cancer cells and explore its regulatory role in the miR-455-3p/ nuclear factor-κB (NF-κB) signaling pathway.Methods:The expression levels of lncRNA SNHG16 and miR-455-3p in human normal cervical epithelial cells H8, human cervical cancer cells SiHa, and radioresistant cervical cancer cells SiHa-R were detected by real-time reverse transcription polymerase chain reaction. SiHa-R cells were transfected separately, and then given a single dose of 4 Gy X-ray irradiation and continued to be cultured for subsequent experiments. The cells in each group were named siRNA-NC, siRNA-SNHG16 (interfering lncRNA SNHG16), NC mimic, miR-455-3p mimic (overexpressing miR-455-3p), siRNA-SNHG16+inhibitor NC, and siRNA-SNHG16+miR-455-3p inhibitor groups, respectively. The survival fraction of SiHa-R cells was detected by clone formation assay. The apoptosis rate of SiHa-R cells was analyzed by flow cytometry. The expression levels of apoptotic proteins [cysteine-containing aspartate-specific protease (Caspase)-3, Caspase-9, Bax] and NF-κB signaling pathway related proteins [NF-κB p65, phosphorylated (p)-NF-κB p65, p-IκB (inhibitory protein of NF-κB)] were measured by Western blot. The targeting relationship between lncRNA SNHG16 and miR-455-3p was determined by dual luciferase reporter gene assay. Comparison among different groups was conducted by one-way ANOVA, and paired comparison was carried out by LSD t-test. Comparison between two groups was performed by t-test. Results:Compared with H8 cells, the expression levels of lncRNA SNHG16 were increased in SiHa and SiHa-R cells, and SiHa-R cells had a higher level than SiHa cells. The expression levels of miR-455-3p were decreased in SiHa and SiHa-R cells, and SiHa-R cells had a lower level than SiHa cells (all P<0.001). Compared with the siRNA-NC group, the survival fraction of SiHa-R cells in the siRNA-SNHG16 group was decreased, the radiosensitization ratio (SER) was 1.571 (>1), the apoptosis rate and levels of Caspase-3, Caspase-9, and Bax proteins were increased, while the levels of p-NF-κB p65 and p-IκB proteins were decreased (all P<0.001). lncRNA SNHG16 could target miR-455-3p. Compared with the NC mimic group, miR-455-3p level in the miR-455-3p mimic group was increased, cell survival fraction was decreased, the SER was 1.826 (>1), the apoptosis rate and the levels of Caspase-3, Caspase-9, Bax proteins were increased, and the levels of p-NF-κB p65 and p-IκB proteins were decreased (all P<0.001). Inhibition of miR-455-3p expression could weaken the effect of interfering with lncRNA SNHG16 expression on SiHa-R cell apoptosis, radiotherapy sensitivity, and NF-κB signaling pathway (all P<0.001). Conclusions:Interference with lncRNA SNHG16 expression could induce the apoptosis of cervical cancer cells and enhance their radiation sensitivity by regulating the miR-455-3p/NF-κB signaling pathway.

Objective The present study was designed to explore the inhibitory effects of the ADC drug Disitamab Vedotin(RC-48)on breast cancer cells with different HER-2 expression levels by utilizing a tumor organoid culture system.Methods Within the framework of the tumor organoid culture system,the breast cancer cell lines MCF-7(characterized by low HER-2 expression,Luminal A subtype)and BT-474(exhibiting high HER-2 expression,HER-2 positive subtype)were cultured independently and in various mixed ratios.The histological characteristics,as well as the expression levels and distribution of HER-2 in MCF-7 and BT-474 organoids,were analyzed via immunohistochemistry and immunofluorescence techniques.MCF-7 and BT-474 organoids were separately treated with Vedotin(RC-48),Disitamab,and Monomethyl auristatin E(MMAE).Additionally,a drug sensitivity test of Disitamab Vedotin(RC-48)was carried out on mixed MCF-7 and BT-474 cell ratios and on patient-derived breast cancer organoids,with the assessment conducted using the 3D-Glo method.Results In the tumor organoid culture system,immunohistochemistry and immunofluorescence analyses demonstrated that HER-2 was predominantly localized in the cell membrane.Specifically,BT-474 organoids exhibited robust HER-2 expression,while MCF-7 organoids displayed relatively low expression levels.When compared with MCF-7 organoids,RC48-ADC exerted a more pronounced inhibitory effect on BT-474 organoids,with IC50 values of 109.7 μg/mL and 2.792 μg/mL,respectively.The co-culture model further confirmed the bystander effect of RC-48,revealing that the ratio of HER-2-positive to HER-2-negative cells significantly influenced drug efficacy.Additionally,treatment with RC-48 led to a reduction in HER-2 expression in breast cancer organoids with diverse HER-2 expression levels.Conclusions The tumor organoid model can accurately mirror drug sensitivity and bystander effects.Within this model,RC-48 effectively inhibited HER-2 highly-expressing breast cancer cells,augmented the killing effect through the bystander mechanism,and downregulated HER-2 expression,thereby suggesting its potential for targeting HER2-associated breast cancer.

Triple-negative breast cancer (TNBC) represents an aggressive breast cancer subtype with poor prognosis and limited targeted treatment options. This investigation examined the anti-cancer potential of Caerulomycin A (Cae A), a natural compound derived from marine actinomycetes, against TNBC. Cae A demonstrated selective inhibition of viability and proliferation in TNBC cell lines, including 4T1, MDA-MB-231, and MDA-MB-468, through apoptosis induction. Mechanistic analyses revealed that the compound induced sustained endoplasmic reticulum (ER) stress and subsequent upregulation of C/EBP homologous protein (CHOP) expression, resulting in mitochondrial damage-mediated apoptosis. Inhibition of ER stress or CHOP expression knockdown reversed mitochondrial damage and apoptosis, highlighting the essential role of ER stress and CHOP in Cae A's anti-tumor mechanism. Both oxygen consumption rate (OCR) and extracellular acidification rate (ECAR) decreased in TNBC cells following Cae A treatment, indicating reduced mitochondrial respiratory and glycolytic capacities. This diminished energy metabolism potentially triggers ER stress and subsequent apoptosis. Furthermore, Cae A exhibited significant anti-tumor effects in the 4T1 tumor model in vivo without apparent toxicity. The compound also effectively inhibited human TNBC organoid growth. These results indicate that Cae A may serve as a potential therapeutic agent for TNBC, with its efficacy likely mediated through the disruption of glucose metabolism and the induction of ER stress-associated apoptosis.

Fetal sacrococcygeal teratoma(SCT)is a rare condition,but the prognosis of fetuses diagnosed with SCT prenatally is generally poor,with a mortality rate of 13% to 50%. The primary causes of death include fetal hydrops and high?output heart failure,while other causes include tumor rupture,hemorrhage,preterm labor,dystocia,or malignant teratoma invasion of surrounding tissues. For large tumors,especially those with rich blood supply or rapid growth,intrauterine treatment should be considered to prevent arteriovenous shunting,reduce tumor size,and reverse fetal heart failure and hydrops. This approach aims to allow the fetus to grow safely to a viable gestational age,after which the tumor can be completely removed by secondary surgery following cesarean delivery or natural childbirth. Currently,there are five main intrauterine treatment strategies:①Ultrasound?guided cystic teratoma aspiration:single or multiple aspirations,intrauterine continuous drainage,or prenatal aspiration;②Ultrasound?guided alcohol sclerotherapy;③Open fetal surgery;④Laser ablation:fetoscopic?guided ablation of feeding vessels of the teratoma,or ultrasound?guided laser ablation;⑤ Ultrasound?guided radiofrequency ablation(RFA).According to the literature,the latter two minimally invasive intrauterine treatment methods show better outcomes for teratomas containing solid components and are gradually becoming the mainstream treatment options.

Objective:To investigate the association between serum 25-hydroxyvitamin D [25(OH)D] levels and 24-h urinary calcium excretion (24-h UCaE) and hypercalciuria in Chinese adults.Methods:This cross-sectional study was conducted from March 2022 to March 2023 in nine cities in China and included 1 239 residents. Demographic characteristics were collected through questionnaires and physical examinations, fasting blood samples were assessed for bone metabolism indicators, and 24-h urine samples were used to determine the 24-h UCaE. Multiple linear regression analysis was used to explore the relationship between serum 25(OH)D and 24-h UCaE and bone metabolism indexes. The relationship between serum 25(OH)D and hypercalciuria was analyzed using a multiple logistic regression model combined with restricted cubic spline modeling.Results:The mean participant age was (47.9±18.1) years, of which 453 (36.6%) were male. The percentages of vitamin D sufficiency, insufficiency, and deficiency were 7.6% (94/1 239), 29.0% (359/1 239), and 63.4% (786/1 239), respectively. The multiple linear regression model showed that after adjusting for the covariates the 24-h UCaE gradually increased with higher levels of 25(OH)D ( P overall <0.001, P nonlinear <0.001). The logistic regression analysis revealed that compared with the vitamin D deficient group, the OR for the prevalence of hypercalciuria in the vitamin D sufficient and vitamin D insufficient groups were 3.290 (95% CI 1.745 to 6.202) and 3.742 (95% CI 2.458 to 5.697), respectively. The results of the restricted cubic spline modeling showed a positive nonlinear relationship between 25(OH)D and the prevalence of hypercalciuria ( P overall <0.001, P nonlinear <0.001). The prevalence of hypercalciuria increased when 25(OH)D was >17.00 μg/L and peaked at 26.71 μg/L, after which there was a decreasing trend in the prevalence of hypercalciuria with increasing 25(OH)D. Conclusion:Associations between serum 25(OH)D levels and urinary calcium excretion and the prevalence of hypercalciuria were observed in the Chinese adult population.

Objective:To construct and evaluate the predictive performance of a multiphase ultrasound radiomics model for microvascular invasion(MVI)in hepatocellular carcinoma(HCC).Methods:A total of 126 patients with pathologically confirmed HCC were retrospectively enrolled from 4 medical centers between May 2018 and July 2025,including the First Hospital of Shanxi Medical University,Shanxi Province Third People's Hospital,Changzhi People's Hospital,and the Organ Transplant Center of the Affiliated Hospital of Qingdao University. A total of 630 ultrasound images of the lesions in different phases were collected,from which 1 561 radiomic features were extracted. The patients from medical institutions in Shanxi Province were chosen as the training set( n=91),and the patients from the Organ Transplant Center of the Affiliated Hospital of Qingdao University were chosen as the validation set( n=35). In the training set,37.4%(34/91)patients presented MVI(+),whereas in the validation set,54.3%(19/35)patients presented MVI(+). Radiomics features were extracted from ultrasound images,and features related to the MVI(+)were selected through dimensionality reduction analysis. Five multiple machine learning algorithms were used to construct predictive models,which were then evaluated using an external validation set. The Radscore was calculated,and a nomogram was constructed combining Radscore with ultrasound and clinical characteristics to predict MVI. Results:The model combining radiomics features from the portal venous phase and the delay phase showed the best predictive performance in both the training and validation sets,with area under curve(AUC)values of 0.835 and 0.727,respectively. The prediction model developed using radiomics Radscore and clinical indicators could be represented and presented as a nomogram.Conclusions:The radiomics model based on multi-phase ultrasound offers a novel approach for non-invasive preoperative prediction of MVI in liver cancer. Furthermore,its integration with clinical features aids in optimizing clinical treatment strategies.
