With the continuous development of refractive surgery, people's focus has gradually shifted from improving vision to improving visual quality, and personalized laser-assisted in situ keratomileusis(LASIK)surgery has gradually become people's preferred choice. Femtosecond laser-assisted keratoplasty provides better advantages for personalized LASIK surgery. This article mainly introduces the commonly used femtosecond laser-assisted personalized LASIK surgery(FS-LASIK)in recent years, such as wavefront-optimized, wavefront-guided, topography-guided, Q value-guided(aspheric cutting), personalized surgery “Wavelight Plus” and personalized surgery when correcting patients with age-related inadequate accommodation. This article focuses on analyzing the advantages and disadvantages of different personalized FS-LASIK, as well as the research progress in recent years, and also focuses on comparing the differences between different personalized surgeries.

This study was aimed at establishing a novel visual detection method for SARS-CoV-2 based on magnetic beads(MBs)enrichment and Au@Pt nanoparticles(Au@PtNPs)enzyme catalysis.According to the double-antibody sandwich method,MBs conjugated with SARS-CoV-2 antibody 1 enriched SARS-CoV-2 antigen in samples.After magnetic adsorption,separation,and washing,the enriched antigen reacted with Au@PtNPs labeled with SARS-CoV-2 antibody 2,thereby forming an immune com-plex.After another round of magnetic adsorption and washing,the color change was catalyzed by Au@PtNPs in the chromogenic solu-tion,and the results were determined through comparison of color changes:a blue color change indicated a positive result,whereas no obvious color change indicated a negative result.The sensitivity and specificity of this method were evaluated.This study successfully established a visual detection method based on MBs enrichment and Au@PtNPs enzyme catalysis for targeting SARS-CoV-2 antigens.The method was able to detect SARS-CoV-2 antigens within 30 minutes and SARS-CoV-2nucleocapsid protein samples with antigen concentrations above 3.125 ng/mL.The method showed no cross-reactivity with seasonal influenza(H1N1)or influenza B virus nu-cleoprotein.The visual detection method established in this study,based on Au@PtNPs enzyme catalysis and MBs enrichment,has high specificity and sensitivity,is simple and quick to operate,and provides a new approach for rapid viral detection.

Cyclotorsion of the eye is a factor that affects the accuracy of astigmatic correction after small incision lenticule extraction(SMILE), potentially leading to unexpected outcomes such as astigmatic undercorrection and an increase in higher-order aberrations. One possible explanation for these issues is the lack of active rotational tracking software in the VisuMax femtosecond laser system. Accurately measuring ocular cyclotorsion can effectively guide the design of the surgery and improve the postoperative visual quality. Several methods have been developed to measure and compensate for cyclotorsion during SMILE. This article reviews the characteristics of cyclotorsion in refractive surgery, the methods of cyclotorsion compensation, and the impact of cyclotorsion compensation on the outcomes of SMILE.

Childhood primary renal tubular diseases are chronic kidney diseases characterized by impaired renal tubular reabsorption. Primary renal tubular disease has diverse clinical manifestations and lacks of specificity. Laboratory tests are limited，making it prone to missed diagnosis and misdiagnosis. Based on the current knowledge of renal tubular diseases，authors propose early warning signals of renal tubular diseases such as family history of primary tubular diseases，unexplained polyhydramnios during pregnancy，polydipsia，polyuria，delayed growth and development or rickets，decreased muscle strength and tone，unexplained electrolyte disturbance，hyperuricemia，acid-base disturbance，positive urine sugar test，renal tubular proteinuria，urinary imaging examination suggesting kidney stones，calcium deposition，renal cysts and early onset of eye，ear，joint and neuron injury.Meanwhile，some universal management strategies for primary renal tubular disease are proposed，emphasizing the importance of multidisciplinary collaboration，genetic testing and individualized intervention to improve the long-term prognosis of childhood primary renal tubular diseases.

Objective:To examine the clinical features and genetic profiles of patients with thyroid peroxidase(TPO) gene mutations and provide diagnostic guidance for clinicians.Methods:A retrospective review of four patients with TPO mutations treated at Ruijin Hospital, Shanghai Jiao Tong University School of Medicine, from January 2014 to December 2023. Data on demographics, clinical manifestation, genotypes, treatment, and prognosis of these patients were analyzed.Results:Two males and two females, aged 13 to 27 years at diagnosis, presented with goiter as the initial symptom, with three cases menifesting during puberty. Laboratory findings showed mildly elevated or upper-limit-normal serum thyroid-stimulating hormone(TSH) levels, significantly increased free triiodothyronine/free thyroxine(FT 3/FT 4) ratios, and elevated thyroglobulin(TG) levels. Genetic testing revealed compound heterozygous pathogenic or likely pathogenic TPO mutations. Despite regular levothyroxine(L-T 4) therapy, goiter persisted. Three patients required thyroidectomy due to cosmetic or compressive symptoms, with pathology showing follicular hyperplasia. Conclusion:TPO mutations are characterized by adolescent-onset goiter, elevated FT 3/FT 4 ratios, and normal to high TSH. Genetic testing confirms the diagnosis. L-T 4 offers limited improvement, and surgery is often needed.

Metastasis serves as an indicator of malignancy and is a biological characteristic of carcinomas. Epithelial-mesenchymal transition (EMT) plays a key role in the promotion of tumor invasion and metastasis and in the enhancement of tumor cell aggressiveness. Prostaglandin E synthase 3 (p23) is a cochaperone for heat shock protein 90 (HSP90). Our previous study showed that p23 is an HSP90-independent transcription factor in cancer-associated inflammation. The effect and mechanism of action of p23 on lung cancer metastasis are tested in this study. By utilizing cell models in vitro and mouse tail vein metastasis models in vivo, the results provide solid evidence that p23 is critical for promoting lung cancer metastases by regulating downstream CXCL1 expression. Rather than acting independently, p23 forms a complex with RNA-binding motif protein 14 (RBM14) to facilitate EMT progression in lung cancer. Therefore, our study provides evidence for the potential role of the RBM14-p23-CXCL1-EMT axis in the metastasis of lung cancer.

Objective To explore the effect of transjugular intrahepatic portosystemic shunt(TIPS)in treating patients with hepatic sinusoidal obstruction syndrome(HSOS)caused by gynura segetum,and to analyze the mid-to-long-term survival.Methods The clinical data of 44 patients with HSOS caused by gynura segetum,who were admitted to the First Affiliated Hospital of University of Science and Technology of China from April 2016 to September 2022 to receive TIPS treatment,were retrospectively analyzed.The preoperative and postoperative liver and kidney functions,ascites,and portal vein pressure were compared.Ultrasonography examination was performed to check the patency of stent and the thickness of ascites,the postoperative complications were recorded.Kaplan-Meier curve was used to calculate the cumulative survival so as to evaluate the survival of patients.Results Based on the severity of the illness,the 44 patients were divided into mild group(n=5),moderate group(n=13),severe group(n=19)and very severe group(n=7).Successful TIPS operation was achieved in all the patients,with a surgical success rate of 100％.No serious complications occurred.After TIPS,the incidence of hepatic encephalopathy(HE)was 20.5％(9/44).The portal pressure decreased from preoperative(42.00±0.91)cm H2 O to postoperative(18.27±0.67)cm H2O,the difference was statistically significant(P＜0.001).The postoperative blood creatinine,aminotransferase,total bilirubin and Child-Pugh score were decreased when compared with their preoperative values,while the albumin level was increased when compared with its preoperative value,the differences were statistically significant(all P＜0.05).The postoperative one-year and 5-year cumulative survival rates were 90.9％and 88.6％respectively.The 1-,3-,6-and 12-month survival rates in mild group were all 100％,in moderate group were 100.0％,100.0％,92.3％and 92.3％respectively,in severe group were 94.7％,94.7％,94.7％and 89.5％respectively,and in very severe group were 85.7％,71.4％,71.4％and 71.4％respectively.Conclusion For the treatment of HSOS caused by gynura segetum,TIPS can significantly improve the patient's ascites with low overall complication rate and high mid-to-long-term survival rate.

Objective:To explore the correlation between thyroid hormone levels and the 90-day prognosis in patients with severe pulmonary tuberculosis, with a particular focus on the impact of age.Methods:This retrospective cohort study included 156 patients(43 females, 113 males; ages ranging from 21 to 93 years)diagnosed with severe pulmonary tuberculosis between January 2022 and December 2023.Patients were categorized into deceased( n=46)and survived( n=110)groups based on their 90-day survival status.Further subcategorization into elderly and non-elderly subgroups was conducted.Thyroid hormone levels and other relevant laboratory markers were measured and analyzed. Results:Total triiodothyronine(TT3) [(0.92±0.36)nmol/L] and free triiodothyronine(FT3) [(2.19±0.87)pmol/L] in deceased group were lower than in survival group [TT3(1.09±0.38)nmol/L], FT3 [(2.79±0.99)pmol/L], both P<0.05.T3 levels positively correlated with 90-day survival (TT3: r=-0.202, P=0.011; FT3: r=-0.276, P<0.001).In elderly patients, this correlation was weakened (TT3: r=-0.071, P=0.526; FT3: r=-0.206, P=0.059), but remained significant in non-elderly patients (TT3: r=-0.360, P=0.002; FT3: r=-0.345, P=0.003).FT3 was a better prognostic indicator than TT3. Conclusions:Low serum T3 levels are indicative of a poor prognosis in severe pulmonary tuberculosis; however, their predictive value diminishes in elderly patients.

The defocus curve, which quantifies visual performance under various defocus states to accurately evaluate the eye's ability to achieve clear vision across a continuous range of distances, is a vital tool for assessing visual quality. With the aging population and improved quality of life driving a significant increase in the demand for presbyopia correction, the application of the defocus curve has continually expanded in ophthalmic clinical practice, particularly in the perioperative period of presbyopia-correcting corneal refractive surgery and refractive cataract surgery, where it aids in personalized surgical planning and proves valuable for patient education and postoperative visual quality assessment. This article systematically reviews the examination methodology, influencing factors, analytical approaches, and recent clinical advancements of defocus curves, focusing on the potential impact of variables such as pupil diameter, contrast sensitivity, and chart selection on results; it further discusses current limitations including lack of standardization and insufficient assessment of dynamic visual performance, and proposes future research directions based on the latest literature. The aim is to provide valuable insights for researchers and clinicians, promote the standardized and normative application of defocus curves, and ultimately enhance the overall efficacy of presbyopia correction and patients' quality of visual life.
