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.

[Purpose]To analyze the trends of incidence and mortality of lung cancer in Jinshan District of Shanghai from 2002 to 2020.[Methods]The data of lung cancer was obtained from the Shanghai Cancer Registry and the population data was obtained from the Jinshan District Bureau of Public Security.The crude rate and age-standardized rate of incidence and mortality(ASIR and ASMR),and the average annual percentage change(AAPC)of lung cancer were calculated.[Results]From 2002 to 2020,8 982 new cases and 6 081 deaths of lung cancer were reported.The ASIR of lung cancer increased from 36.55/105 to 56.72/105 with an AAPC of 3.34％(P＜0.05).The ASIR was also increased in male and female,with higher increase in female(AAPC=8.56％)than that in male(AAPC=0.50％).The ASMR decreased from 32.25/105 to 23.06/105 with an AAPC of-2.08％(P＜0.05).The ASMR was decreased both in male and female,with higher decline in male(AAPC=-2.71％)than that in female(AAPC=-0.43％).The disease risk in male was higher than that in female,while the difference in ASIR between male and female was decreasing.The inci-dence and mortality increased with age.[Conclusion]From 2002 to 2020,the incidence of lung cancer in Jinshan District was increasing,but the age-standardized mortality was decreasing.The incidence and mortality of lung cancer varied among different ages and sexes,so targeted preven-tion and control measures should be implemented.

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 (T_1/2) 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.
