AIM: To compare and analyze the efficacy of femtosecond laser-assisted in situ keratomileusis(FS-LASIK)with small incision lenticule extraction(SMILE)in the treatment of moderate myopia.METHODS:Retrospective study. A total of 100 patients(100 eyes)with moderate myopia admitted to our hospital from August 2022 to October 2024 were selected(all the data of the right eye were taken for study). The 52 cases in FS-LASIK group received FS-LASIK, while the 48 cases in SMILE group received SMILE. The patients were followed up for 6 mo, the visual recovery, spherical equivalent, corneal curvature, corneal Q value, central corneal thickness, corneal volume, high-order aberrations, corneal biomechanical parameters and incidence of complications were compared between the two groups.RESULTS: At 3 and 6 mo after surgery, the uncorrected visual acuity(UCVA)and spherical equivalent of both groups increased compared to before surgery(all P<0.05). At 6 mo after surgery, both groups showed a decrease in corneal curvature, central corneal thickness, and corneal volume, with the FS-LASIK group having a lower corneal volume; both groups showed a great increase in Q values, with the FS-LASIK group having a higher Q value(all P<0.001); the total high-order aberration, spherical aberration, and trefoil aberration all increased in both groups, with higher values observed in the FS-LASIK group(all P<0.001); the integrated radius(IR), inverse concave radius(ICR)and deformation amplitude ratio 2(DAR2)were all increased, while the stiffness parameter at first applanation(SP-A1), the highest concavity radius(HC-Radius)and the ambrosio's relational thickness to the horizontal profile(ARTh)were all decreased in both groups(all P<0.001). There was no statistical difference in the incidence of complications between two groups(P>0.05).CONCLUSION: Both FS-LASIK and SMILE can help improve the visual quality of patients with moderate myopia, and their early postoperative corneal morphological changes have their own characteristics. In addition, patients who receive FS-LASIK have larger corneal Q value and high-order aberrations after surgery.

Objective To analyze the death rate and life loss of injuries in Jinshan District of Shanghai from 1990 to 2023, and to provide a scientific basis for the formulation of injury prevention and control measures. Methods Excel 2010 was used to establish a database for injury death reports in Jinshan District from 1990 to 2023, and the crude mortality rate, standardized mortality rate, age-specific mortality rate, potential years of life lost (PYLL), rate of potential years of life lost (PYLLR) and standardized rate of potential years of life lost (SPYLLR) were calculated. Results From 1990 to 2023, the crude mortality rate due to injuries in Jinshan District was 52.25/100 000, while the standardized mortality rate was 36.95/100 000. Based on the standardized mortality rate, the top four causes of injury-related deaths were traffic accidents, falls, drowning, and suicide. Traffic accidents ranked first as the leading cause of death for both males (19.30/100 000) and females (8.41/100 000). The top cause of death for the 0-14 years old group was drowning, the 15-64 years old group was traffic accidents, and the 65 years old and above was falls. Over the 34-year period, according to SPYLLR, the top four causes of death for both genders were consistently traffic accidents, drowning, suicide, and falls. Conclusion From 1990 to 2023, traffic accidents, falls, drowning, and suicide have been the primary causes of injury-related deaths in Jinshan District, Shanghai. It is essential to develop targeted prevention and control strategies based on the specific characteristics of these injury-related fatalities.

Bone repair remains an important target in tissue engineering, making the development of bioactive scaffolds for effective bone defect repair a critical objective. In this study, β-tricalcium phosphate (β-TCP) scaffolds incorporated with processed pyritum decoction (PPD) were fabricated using three-dimensional (3D) printing-assisted freeze-casting. The produced composite scaffolds were evaluated for their mechanical strength, physicochemical properties, biocompatibility, in vitro pro-angiogenic activity, and in vivo efficacy in repairing rabbit femoral defects. They not only demonstrated excellent physicochemical properties, enhanced mechanical strength, and good biosafety but also significantly promoted the proliferation, migration, and aggregation of pro-angiogenic human umbilical vein endothelial cells (HUVECs). In vivo studies revealed that all scaffold groups facilitated osteogenesis at the bone defect site, with the β-TCP scaffolds loaded with PPD markedly enhancing the expression of neurogenic locus Notch homolog protein 1 (Notch1), vascular endothelial growth factor (VEGF), bone morphogenetic protein-2 (BMP-2), and osteopontin (OPN). Overall, the scaffolds developed in this study exhibited strong angiogenic and osteogenic capabilities both in vitro and in vivo. The incorporation of PPD notably promoted the angiogenic-osteogenic coupling, thereby accelerating bone repair, which suggests that PPD is a promising material for bone repair and that the PPD/β-TCP scaffolds hold great potential as a bone graft alternative.

Total laryngectomy is a crucial surgical intervention for patients with advanced malignant tumors of the larynx and nasopharynx. Despite its effectiveness, this procedure permanently severs the connection between the nasal cavity and the lower respiratory tract, leading to the cessation of nasal airflow. This disruption significantly impairs the patient's sense of smell and adversely affects their quality of life. Although olfactory loss is common in these patients, the assessment and rehabilitation of their olfactory function are often overlooked. This article reviews relevant literature on evaluating olfactory function and rehabilitation methods following total laryngectomy, with the aim of providing a theoretical foundation to enhance olfactory rehabilitation and overall quality of life for these patients.

ADC189 is a novel drug of cap-dependent endonuclease inhibitor. In our study, its antiviral efficacy was evaluated in vitro and in vivo, and compared with baloxavir marboxil and oseltamivir. A first-in-human phase I study in healthy volunteers included single ascending dose (SAD) and food effect (FE) parts. In the preclinical study, ADC189 showed potent antiviral activity against various types of influenza viruses, including H1N1, H3N2, influenza B virus, and highly pathogenic avian influenza, comparable to baloxavir marboxil. Additionally, ADC189 exhibited much better antiviral efficacy than oseltamivir in H1N1 infected mice. In the phase I study, ADC189 was rapidly metabolized to ADC189-I07, and its exposure increased proportionally with the dose. The terminal elimination half-life (T1/2) ranged from 76.69 to 98.28 hours. Of note, food had no effect on the concentration, clearance, and exposure of ADC189. It was well tolerated, with few treatment-emergent adverse events (TEAEs) reported and no serious adverse events (SAEs). ADC189 demonstrated excellent antiviral efficacy both in vitro and in vivo. It was safe, well-tolerated, and had favorable pharmacokinetic characteristics in healthy volunteers, supporting its potential for single oral dosing in clinical practice.

ObjectiveTo investigate the possible mechanism of Huatan Sanjie Formula (化痰散结方, HSF) in treating Graves' disease (GD) from the perspective of thyroid angiogenesis. MethodsThirty-six BALB/c female mice were randomly divided into a normal control group (n=9) and a modeling group (n=27). Mice in the modeling group were injected with 2.0×109 PFU/ml of Ad-TSHR289 adenovirus into the tibialis anterior muscle to build GD model. Nine weeks after immunization, the successfully modeled mice were randomly divided into model group, methimazole (MMI) group and HSF group, with 9 mice in each group. The MMI group was given 5.2 mg/(kg·d) of methimazole tablets by gavage, while the HSF group was given HSF at a relative crude drug dosage of 7.02 g/(kg·d) by gavage. The normal control group and the model group were given 0.1 ml/10 g of pure water by gavage. All groups were administered intragastrically once a day for a total of 4 weeks. The levels of thyroxine (T4) and thyrotropin receptor autoantibodies (TRAb) in serum were detected by radioimmunoassay, while the pathological changes of the thyroid gland were assessed by HE staining. The vascular morphology of thyroid tissue was observed by CD34 immunohistochemical staining, and the microvessel density (MVD) was counted. The protein expression of vascular endothelial growth factor A (VEGFA) and vascular endothelial growth factor receptor 2 (VEGFR2) in thyroid was detected by Western-blot. ResultsCompared to those in the normal control group, the thyroid volume of the mice in the model group significantly increased with excessive congestion, and the pathology showed significant thyroid follicular hyperplasia, columnar and proliferated epithelial cells, and enlarged follicle size; serum T4 and TRAb significantly increased, as well as the count of thyroid MVD, and the protein expressions of thyroid VEGFA and VEGFR2 (P<0.01). Compared to those in the model group, the thyroid glands of the mice in the MMI group and the HSF group were significantly reduced, and the congestion was improved; pathology showed that thyroid follicular hyperplasia and epithelial cell proliferation were reduced, with smooth edges of the follicles and the significantly reduced inward protrusion; serum T4 and TRAb significantly decreased, as well as the thyroid MVD, thyroid VEGFA and VEGFR2 protein expressions (P<0.05 or P<0.01). There was no significant difference in all indicators between the MMI group and the HSF group (P>0.05). ConclusionHSF may inhibit thyroid angiogenesis by down-regulating thyroid VEGFA/VEGFR2 signaling pathway, thereby improving goitre and hyperfunction in GD mice.

Objective:To analyze the differentially expressed genes of human respiratory syncytial virus (RSV) subtype A genotype ON1, a predominant genotype in Beijing, after infecting A549 cells using transcriptomic sequencing, and provide potential targets for RSV prevention and treatment.Methods:A local strain (61397-ON1) identified by whole-genome sequencing as ON1 genotype of RSV subtype A was selected to infect A549 cells. Total mRNA was extracted, and the differentially expressed genes in infected and uninfected A549 cells were screened by transcriptomic sequencing. GO analysis and KEGG pathway analysis were performed. Besides, six genes with differential expression ratio greater than two times were randomly selected for qRT-PCR verification.Results:There were 1 632 differentially expressed genes between infected and uninfected A549 cells, of which 807 genes were up-regulated and 825 genes were down-regulated. The differentially expressed genes were mainly involved in immune response-related biological processes such as cytokine response and positive regulation of MAPK cascades, and were enriched in MAPK signaling pathway, NOD-like receptor signaling pathway, p53 signaling pathway, TNF signaling pathway, IL-17 signaling pathway and NF-κB signaling pathway. The results of qRT-PCR for six differentially expressed genes were consistent with the trend of transcriptome data.Conclusions:The differentially expressed genes of RSV A subtype ON1 genotype after infecting A549 cells are mainly involved in cytokine response and immune-related signaling pathways. This study provides basic data for further study of the molecular mechanism of RSV infection and the development of prevention and treatment strategies.
