Objective:To explore the efficacy and safety of the Da Vinci robotic single-port-plus-one technique in common urological surgeries in children.Methods:The data of 59 children who underwent robot-assisted single-port-plus-one laparoscopic surgery from May 2022 to November 2023 in Fuzhou University Affiliated Provincial Hospital were retrospectively analyzed. There were 44 males and 15 females, aged 36 (6, 108)months. Among them, 27 cases had ureteropelvic junction obstruction, with a preoperative anterior-posterior diameter of the renal pelvis of (31.83±6.59) mm. The American Society of Fetal Urology (SFU) grading system revealed grade Ⅲ in 8 sides and grade Ⅳ in 19 sides. Bilateral renal function showed a difference of 13.50% (7.18%, 31.06%). Additionally, 17 cases presented with vesicoureteral reflux. Preoperative voiding cystourethrogram (VCUG) indicated reflux grades Ⅲ, Ⅳ, and Ⅴ in 8, 14, and 4 sides, respectively, with a difference in bilateral renal function of 18.58% (6.04%, 28.30%). Ten cases had obstructive megaureter, with a preoperative renal pelvis diameter of (22.17±7.64)mm and a maximum ureteral diameter of (19.51±3.71)mm. The preoperative bilateral renal function difference was 18.02% (5.23%, 49.42%).Five cases involved duplicated kidney and ureter. Magnetic resonance urography (MRU) confirmed unilateral duplicated kidneys with associated dilatation of the upper renal pelvis and calyces, hydroureter, thin renal cortex in all 5 patients. Among them, 2 cases had ectopic ureteral opening and 1 case had terminal ureteral cyst. Patients with ureteropelvic junction stenosis underwent pyeloplasty, those with vesicoureteral reflux and obstructive megaureter underwent ureteral reimplantation, and patients with duplicated ureters underwent nephrectomy. The Da Vinci robotic surgical system was employed for all procedures. The port placement technique involved a 2-3 cm incision around the navel to insert a single-port four-channel device, followed by the placement of an additional 8 mm operating channel in the left or right abdomen under direct visualization based on the surgical site. Preoperative and postoperative parameters were compared.Results:All operations were successfully completed without conversion to open or laparoscopic surgery. The operation time of the ureteropelvic junction obstruction children was (141.52±22.93) min. The postoperative renal pelvis diameter and bilateral renal function difference were (12.54±4.05) mm and 5.60%(2.14%, 14.48%), respectively, both of which showed significant improvement compared to preoperative levels ( P<0.01). Postoperative hydronephrosis grades were as follows: 13 sides with grade Ⅰ, 13 sides with grade Ⅱ, and 1 side with grade Ⅲ. The operation time of vesicoureteral reflux children was (125.00±11.75) min in the unilateral group and (153.22±14.39) min in the bilateral group. Postoperatively, 2 sides demonstrated reflux grade Ⅰ, 1 side grade Ⅱ, and 1 side grade Ⅲ, indicating improvement compared to preoperative levels. Bilateral renal function difference post-surgery was 13.34% (1.85%, 20.54%), which was more balanced than preoperatively ( P=0.011). Postoperative renal pelvis anterior-posterior diameter and maximum ureteral diameter were reduced to (10.31±3.86) mm and (6.62±2.44) mm, respectively, which were significantly smaller than preoperative measurements ( P<0.01). The bilateral renal function difference post-surgery was 12.04% (4.85%, 47.53%), showing improvement, though not statistically significant ( P=0.508). The operation time of the repeated nephrectomy children was (140.00±12.75) min. No recurrence of preoperative symptoms was noted, and renal cortical function remained generally normal during follow-up. In this study, only 3 cases of obstructive megaureter developed febrile urinary tract infection within 1 month after surgery, and no complications were observed in the remaining cases. Conclusions:This study preliminarily confirmed that the Da Vinci robotic single-port-plus one-port technology can be used in the treatment of common diseases of the urinary system in children. The patients' symptoms were significantly relieved after surgery, and the indicators of hydronephrosis improved compared with those before surgery. The incidence of postoperative complications was low, and aesthetic outcomes of postoperative scars were enhanced. Further studies are needed to assess its long-term efficacy.

Objective To investigate the factors that influence ocular surface biology and visual acuity in individuals with diabetic dry eye(DDE)and analyze how these factors contribute to changes in visual quality.Methods Based on the disease duration,fasting blood glucose(FBG),and glycated hemoglobin(HbA1c)levels of patients with type 2 diabe-tes mellitus(T2DM),the DDE patients were divided into different groups.Logistic regression analysis was used to identify influencing factors related to ocular surface biology and visual quality in each group of DDE patients.Tear film stability was evaluated based on the tear film rupture time(BUT),Schirmer I test(SIt),and ocular surface disease index(OSDI).Lip-iview? Surface interferometers were used to measure tear film lipid layer thickness(LLT),meibomian gland loss rate(MGP),meibomian gland opening number(MGYLS),and meibomian gland secretion score(MGYSS).Wavefront aber-rometry was used to measure corneal wavefront aberration values at 4 mm and 6 mm pupil diameters.Ocular response ana-lyzer(ORA)was adopted to analyze corneal hysteresis(CH)and corneal resistance factor(CRF).Moreover,ELISA ex-periment to evaluate the trend of changes in inflammatory factors in tears.Results Logistic regression analysis revealed that T2DM duration,smoking history,FBG,HbA1c,total cholesterol(TC),triglycerides(TG),OSDI score,LLT,BUT,SIt,MGP,MGYLS,MGYSS,total higher-order aberrations,spherical aberration,coma aberration,trefoil aberration,tumor necrosis factor-α,interleukin-6,matrix metalloproteinase-9,receptor for advanced glycation end products,and insu-lin were all influencing factors for the risk of DDE(all P＜0.05).As the T2DM course prolonged and FBG or HbA1 c levels rose,tear film-related indicators(LLT,BUT,and SIt)and meibomian gland-related indicators(MGYLS and MGYSS)inpa-tients gradually decreased,while OSDI scores and MGP gradually increased(all P＜0.05).As the T2DM course prolonged and FBG or HbA1c levels rose,the total higher-order aberrations,spherical aberration,coma aberration,and trefoil aber-ration in DDE patients under 4 mm and 6 mm pupil diameters gradually increased;Meanwhile,best corrected visual acuity,corneal hysteresis,and corneal resistance factor gradually decreased;The contents of tumor necrosis factor-α,interleukin-6,matrix metalloproteinase-9,receptor for advanced glycation end products,and insulin in tears all gradually increased,while mucin-5AC gradually decreased(all P＜0.05).Conclusion With the prolongation of T2DM duration and the in-crease of FBG or HbA1c,the ocular surface inflammatory response in DDE patients gradually worsens,corneal biological function decreases,and visual quality deteriorates.Timely systemic and local interventions are of great significance for im-proving dry eye symptoms and visual quality in DDE patients.

Objective To investigate the relationship between the threonine and tyrosine kinase(TTK)gene and eyelid basal cell carcinoma(BCC).Methods Bioinformatics methods were used to screen the core gene(namely,TTK)associated with the occurrence and development of BCC from the Gene Expression Omnibus(GEO)database.Surgically removed eyelid BCC tissue specimens(BCC cells were divided into BBC Grade Ⅰ,Ⅱ and Ⅲ groups by tumor grade)and be-nign tumor tissue specimens(Control group)were collected from Ziyang Central Hospital for subsequent experiments.Cel-lular immunofluorescence assay(CIA)was used to detect the expression of the TTK gene in benign and malignant eyelid tumor cells.After knocking down TTK in BCC cells through transfection with lentiviruses(the cells transfected with LV-TTK-shRNA were taken as the TTK-shRNA group,and those transfected with LV-BBC-shRNA were taken as the BBC nega-tive control group),CIA was used to detect the expression of key proteins Bcl-2 and Bax in the apoptotic signaling pathway of each group of cells.Results The bioinformatics analysis showed that the TTK gene was the core gene associated with the occurrence and development of eyelid BCC.CIA detection results revealed that the fluorescence signal intensities in the tumor cytoplasm of Control,BCC Grade Ⅰ,Ⅱ,and Ⅲ groups were 1.03±0.07,1.28±0.11,1.58±0.13 and 1.92±0.17,respectively.The fluorescence signal intensity gradually increased,and the difference in fluorescence signal intensity among the four groups was statistically significant(all P＜0.05).Compared with that in the Control group(1.02±0.05),the cell fluorescence intensity was increased in the BCC negative control group(1.74±0.12)and decreased in the TTK-shRNA group(1.31±0.09)(P＜0.05).The difference in cell fluorescence intensity was significant among the Control,BCC nega-tive control and TTK-shRNA groups(all P＜0.05).The fluorescence intensity of the anti-apoptotic protein Bcl-2 was 1.04±0.12 in the Control group,2.12±0.23 in the BCC negative control group,and 1.43±0.15 in the TTK-shRNA group.The fluorescence intensity of the pro-apoptotic protein Bax was 1.02±0.08 in the Control group,0.64±0.11 in the BCC negative control group,and 1.47±0.16 in the TTK-shRNA group.After TTK knockdown,the expression level of BcL-2 in BCC cells decreased,and that of Bax increased.The fluorescence intensities of BcL-2 and Bax were significantly different among the Control,BCC negative control and TTK-shRNA groups(all P＜0.05).Conclusion The TTK gene plays a role in the regulation of eyelid BCC cell proliferation,and this effect is closely related to the PI3K-AKT-Bcl-2/Bax signaling path-way.

Objective:To investigate associations between cardiac biomarkers with stroke severity and short-term outcome in patients with acute ischemic stroke (AIS).Methods:Patients with AIS admitted to the Affiliated Hospital of Qingdao University from June 2018 to February 2024 whose etiological classification was large artery atherosclerosis (LAA), small vessel occlusion (SVO) or cardioembolism (CE) were included retrospectively. According to the National Institutes of Health Stroke Scale score at admission, patients were divided into mild stroke group (≤8) and moderate to severe stroke group (>8). According to the modified Rankin Scale score at discharge, patients were divided into good outcome group (≤2) and poor outcome group (>2). Multivariate logistic regression analysis was used to determine the independent correlation between cardiac biomarkers and short-term outcome. The predictive value of cardiac biomarkers for poor outcome in patients with AIS and different stroke etiology subtypes were evaluated using receiver operating characteristic (ROC) curves. Results:A total of 2 151 patients with AIS were enrolled, including 1 256 males (58.4%), aged 67.40±11.34 years. 1 079 patents were LAA type (50.2%), 679 were SVO type (31.6%), and 393 were CE type (18.3%); 1 223 were mild stroke (56.86%) and 928 (43.14%) were moderate to severe stroke; 1 357 patients (63.09%) had good short-term outcome, and 794 (36.91%) had poor short-term outcome. Multivariate logistic regression analysis showed that N-terminal pro-B type natriuretic peptide (NT-proBNP), NT-proBNP/creatine kinase (CK) isoenzyme MB (CK-MB) ratio, and CK-MB/CK ratio were independent risk factors for poor short-term outcome. ROC curve analysis shows that the CK-MB/CK ratio had a higher predictive value for short-term poor outcome in patients with AIS (the area under the curve, 0.859, 95% confidence interval 0.839-0.879). Various cardiac biomarkers had a higher predictive value for short-term outcome of CE type and LAA type, but the predictive value for short-term outcome of SVO type was lower. Conclusions:Cardiac biomarkers are associated with the severity and poor outcome of AIS. NT-proBNP/CK-MB and CK-MB/CK ratios have higher predictive value for short-term poor outcome of AIS, especially in patients with CE type.
