AIM: To evaluate the visual function and optical quality in adults aged 80y and older following the bilateral implantation of zonal refractive multifocal intraocular lens(IOL, LS-313 MF30).METHODS: A single-center, non-randomized, prospective clinical trial was conducted, involving cataract patients aged 80 y and older. Patients received bilateral implantation of the LS-313 MF30 or CT Asphina 409MP, based on personal preference. Postoperative assessments included uncorrected and corrected visual acuity at distance, intermediate, and near ranges, as well as defocus curve. Subjective evaluations were performed using the visual function(VF-14)questionnaire, spectacle independence rates, and patient satisfaction surveys. Photic phenomena such as glare, halos, and starbursts were also analyzed.RESULTS: The MF30 group(16 eyes from 8 participants, 85.38±2.56 y)exhibited superior uncorrected and corrected intermediate and near visual acuity compared to the 409MP group(26 eyes from 13 participants, 85.77±2.20 y), while distance visual acuity was comparable between groups. The defocus curve of the MF30 group revealed two peaks at 0.00 D and -3.00 D, indicating a broader depth of focus. Patients in the MF30 group reported higher rates of spectacle independence and greater satisfaction. While photic phenomena such as glare(28.6% vs 18.5%, P=0.584), starburst(9.5% vs 3.7%, P=0.567)and halos(23.8% vs 11.11%, P=0.438)were more prevalent in the MF30 group, they were generally mild and did not significantly impact daily activities.CONCLUSION: Zonal refractive multifocal IOLs provide elderly patients with improved distance and near vision, greater spectacle independence, and greater satisfaction. Although photic phenomena were slightly more frequent with MF30, they are generally reported as non-disruptive and do not affect their daily life compared to monofocal IOLs.

Objective To observe the value of transabdominal bowel ultrasound for monitoring therapeutic efficacy of vedolizumab in patients with moderate-to-severe ulcerative colitis.Methods Totally 47 ulcerative colitis patients with Mayo endoscopic score(MES)≥2 and treated with vedolizumab were retrospectively included.Transabdominal bowel ultrasound examinations were performed at baseline,at the end of induction therapy,also 3 and 6 months after maintenance therapy,while colonoscopy was performed at baseline and 6 months after maintenance therapy.According to colonoscopy results 6 months after maintenance therapy,the patients were divided into improved group(MES≤1 or MES reduction≥1,n=25)and non-improved group(n=22),and ultrasonic findings of sigmoid colon were compared between and within groups.Results At baseline,no significant difference of ultrasonic findings of sigmoid colon was observed between groups(all P＞0.05),whereas differences of bowel wall thickness at the end of induction therapy,of Limberg grade and abnormal perienteric lymph nodes 3 months after maintenance therapy,as well as bowel wall stratification 6 months after maintenance therapy were noticed between groups(all P＜0.05).Within improved group,compared with those in baseline,bowel wall thickness improved at all time points after the beginning of treatment,Limberg grade improved 3 and 6 months after maintenance therapy,while bowel wall stratification,abnormal perienteric lymph node and perienteric fat edema improved 6 months after maintenance therapy(all P＜0.05).Meanwhile,no significant change of ultrasonic findings of sigmoid colon was observed in non-improved group during the above periods(all P＞0.05).Conclusion Transabdominal bowel ultrasound could be used to accurately monitor the therapeutic efficacy of vedolizumab in patients with moderate-to-severe ulcerative colitis.

The incidence of malignant tumors among elderly patients is increasing.Influenced by multiple factors such as aging,tumor,and drug,this population exhibits a high prevalence of renal insufficiency.However,there remains a scarcity of research data and significant challenges in clinical management.This article systematically an-alyzes the challenges faced in administering anti-tumor therapies to elderly patients with renal insufficiency and pro-poses management strategies.Optimization approaches include precise assessment of renal function,selection of nephrotoxicity-sparing medications,appropriate dose adjustments,implementation of preventive measures,and em-phasis on comprehensive geriatric assessment and multidisciplinary collaboration.Renal injury management should be individualized,with considerations for special populations such as renal transplant recipients and dialysis pa-tients.Future efforts should focus on biomarker discovery and the development of low-nephrotoxicity therapeutic agents to address these complex clinical challenges.

Objective To establish,evaluate and validate the Nomogram prediction model of radiation pneumonitis(RP)in intensity modulated radiotherapy(IMRT)with TCM syndrome elements.Methods 257 patients with locally advanved non-small cell lung cancer receiving IMRT were analyzed retrospectively.The total population was randomly divided into a training set and a validation set by 7:3.A prediction model was established by Lasso-Logistic regression analysis,and then visualized by Nomogram to evaluate and validate the model.Results Independent risk factors included in the prediction model included tumor stage(OR=6.576;P=0.003),position(OR=2.935;P=0.016),MLD of the affected lung(OR=1.001;P<0.001)and Yin deficiency(OR=3.861;P=0.003).Based on the above factors,the prediction model was constructed and visualized.The C-index of the training set and the validation set were 0.865 and 0.867,respectively.The calibration curves of the two sets had a good fit and had certain clinical usefulness.Conclusion Based on the clinical elements of Chinese and Western medicine,tumor stage,position,lung MLD and Yin deficiency,the model can accurately predict the occurrence of≥grade 2 RP,and provide a reference for clinical screening of high-risk patients and further improvement of treatment plan.

Nanobodies (Nbs), the unique single-domain antibodies discovered in the species of Camelidae and sharks, are also known as the variable domain of the heavy chain of heavy-chain antibody (VHH). They offer strong antigen targeting and binding capabilities and overcome the drawbacks such as large size, low stability, high immunogenicity, and slow clearance of conventional antibodies. Nbs can be boosted by bioconjugation with toxins, enzymes, radioactive nucleotides, fluorophores, and other functional groups, demonstrating potential applications in the diagnosis and treatment of human and animal diseases. This article introduces the structures and characteristics of Nbs, the construction and screening of Nb libraries, and the strategies for affinity maturation and then reviews the current applications of Nbs in diagnosis and treatment, providing a reference for the development of diagnostic reagents and clinical therapies for infectious diseases.

Objective To evaluate the effects of Baihe Gujin Decoction on long-term survival in patients with non-small cell lung cancer(NSCLC)receiving radiotherapy(RT)in the real world.Methods Retrospective data from patients with NSCLC receiving RT in the Longhua Hospital Affiliated to Shanghai University of Traditional Chinese Medicine(TCM)and data from patients in the Surveillance,Epidemiology and End Results(SEER)database were collected and grouped as the TCM+conventional Western medicine(CWM)cohort and CWM cohort,respectively.Propensity score matching(PSM)was used to balance confounders between groups.Kaplan-Meier curve and Cox regression model were used to estimate the effects of Baihe Gujin Decoction on survival outcomes of patients receiving RT.Results Totally 190 samples with a balance between groups were obtained using PSM.Overall survival(OS)analysis showed that the TCM+CWM cohort had significantly longer OS than the CWM cohort(P=0.004).Subgroup analysis showed that the Baihe Gujin Decoction was more advantageous in the characteristic population of age≥65 years(P=0.027),male(P=0.010),T3-T4 stage(P<0.001),N2-N3 stage(P=0.026),M1 stage(P<0.001),not receiving chemotherapy(P<0.001),and not undergoing surgery(P<0.001).Multivariate Cox regression confirmed that treatment group(P=0.003),T(P=0.003)and M stages(P=0.002)may be the independent prognostic factors for OS of NSCLC patients treated with RT.Conclusion Baihe Gujin Decoction probably can improve the long-term prognosis in NSCLC patients treatment with RT.

Enhanced recovery after surgery has reduced the number and duration of medical catheter placements through perioperative optimization measures. However, in clinical practice, catheters are still inevitably heavily used, and the risk of catheter-related infections persists. Preventing bacterial adhesion and biofilm formation on catheter surfaces is crucial. Medical antibacterial-coated catheters introduce substances that prevent fouling and adhesion, inhibit or kill bacteria on the surface, forming an antibacterial functional surface, providing a new strategy to address catheter-related infections. This article summarizes the current research status of medical antibacterial-coated catheters, introduces the antibacterial strategies and principles of the coatings, describes their actual effects in clinical applications, and analyzes future research directions. These studies help reduce catheter-related infections, promote innovation in clinical nursing technology, and improve the quality and efficiency of nursing care.
