Objective To explore the influence of Da Vinci robot-assisted different approaches of laparoscopic partial nephrectomy(LPN)on the renal function and intestinal function recovery in the treatment of central renal tumors.Methods Totally 100 patients with central renal tumors who received Da Vinci robot-assisted LPN in the Central Hospital of Enshi Tujia and Miao Autonomous Prefecture were selected from November 2022 to March 2024.According to the consent of the patients,they were divided into transperitoneal group and retroperitoneal group by envelope drawing method,with 50 cases in each group.The transperitoneal group adopted transperitoneal approach,while the retroperitoneal group received retroperitoneal approach.The surgical status and postoperative recovery status,renal function[serum creatinine(Scr),glomerular filtration rate(GFR)and blood urea nitrogen(BUN)],intestinal function recovery status[restore exhaust time,plasma diamine oxidase(DAO),D-lactic acid and urinary lactulose/mannose(L/M)]and complications were compared between groups.Results The surgical time,intraoperative blood loss,renal warm ischemia time,restore exhaust time,urinary catheter indwelling time and hospitalization time with(126.76±23.89)h,(115.86±6.93)ml,(25.41±6.57)min,(2.29±0.56)d,(4.89±0.93)d and(11.08±1.92)d in transperitoneal group were longer or more than the retroperitoneal group[(111.58±21.86)h,(86.27±6.71)ml,(17.08±5.16)min,(1.73±0.43)d,(3.16±0.62)d and(9.29±2.07)d,all P＜0.05].1 month after surgery,the SCr level in transperitoneal group with(83.04±10.13)μmol/L was lower than(88.55±9.16)μmol/L in retroperitoneal group while the GFR value with(58.27±6.19)ml/min was higher than(54.36±6.05)ml/min in retroperitoneal group(P＜0.05).The levels of DAO,D-lactic acid and the value of urine L/M with(3.39±0.57)mg/L,(2.09±0.31)mg/L and(0.08±0.02)in transperitoneal group at 24 hours after surgery,which were higher than the retroperitoneal group[(3.07±0.46)mg/L,(1.72±0.25)mg/L and(0.05±0.02),P＜0.05].The total incidence rates of postoperative complications in transperitoneal group and retroperitoneal group were 12.00％and 8.00％(P＞0.05).Conclusion The two approaches of LPN assisted by Da Vinci robot have their own advantages in the treatment of central renal tumors.Transperitoneal approach is more conducive to improving renal function,but retroperitoneal approach is more conducive to shortening the postoperative recovery time and promoting the intestinal function recovery and has lower incidence rates of complications.

Objective To evaluate the application of novel oral anticoagulants(NOACs)in the treatment of elderly patients with non-valvular atrial fibrillation(NVAF),and to provide a basis for the rational use of drugs in clinical practice.Methods Based on the Beers criteria(2023 edition),combined with drug instructions and relevant guidelines,the potential inappropriate medication(PIM)evaluation criteria of NOACs in NVAF patients were formulated.The medication PIM of patients aged 80 years or older who were hospitalized in the cardiovascular department from January to December 2023 was analyzed when using NOACs.Results A total of 78 cases were included,and 47 cases of PIM occurred in NOACs,including 1 case of renal function-related PIM(2.13％),and 46 cases of drug interaction related PIM(97.87％).There were 72 patients who do not meet the evaluation criteria of the 2023 version of the Beers standard.Conclusion The updated Beers standard has not yet been widely adopted in clinical practice.The highest incidence of PIM in the use of NOACs in elderly patients with NVAF is due to drug interactions.It is necessary to strengthen drug monitoring in elderly patients with NVAF and promote rational drug use.

AIM:This study aims to investigate the regulatory effect of the endocannabinoid 2-arachidonoyl glycerol(2-AG)on voltage-gated calcium channels(VGCCs)in caudate nucleus(CN)neurons subjected to kainic acid(KA)-induced damage,and to elucidate the underlying mechanisms involved.METHODS:Primary cultured CN neu-rons from neonatal Sprague-Dawley(SD)rats were treated with KA to establish an excitotoxic cellular model.The whole-cell patch-clamp technique was utilized to assess the effects of 2-AG on KA-induced excitotoxicity,along with the changes in the electrical properties of VGCCs.This included evaluations of current density,current-voltage relationships,and the kinetics of channel activation and inactivation.RESULTS:Treatment with KA significantly increased the current density and altered the electrical properties of VGCCs,as indicated by a reduction in the half-inactivation voltage and a shift of the inactivation curve towards depolarized potentials.Notably,KA did not affect the activation characteristics of VGCCs.Ad-ministration of exogenous 2-AG or the application of the monoacylglycerol lipase inhibitor URB602,which inhibits 2-AG degradation and elevates intracellular levels of 2-AG,effectively inhibited the KA-induced increase in VGCC current den-sity and the depolarization shift of the inactivation curve,highlighting the involvement of cannabinoid receptor 1(CB1R).CONCLUSION:The endocannabinoid 2-AG can modulate the function of VGCCs in CN neurons via the CB1R pathway,offering protective effects against excitotoxic damage induced by KA.

AIM: To evaluate the diopter errors and safety of secondary intraocular lens(IOL)implantation in the ciliary sulcus using a modified incision procedure in children with bilateral aphakia.METHODS: The data of 12 children(24 eyes)with bilateral aphakia who had undergone secondary foldable IOL implantation in the ciliary sulcus using a modified incision procedure from 2020 to 2021 were retrospectively reviewed. Incision-related complications were analyzed intraoperatively and at 1 d and 1 mo postoperatively. Best-corrected visual acuity(BCVA), axial length(AL), white-to-white(WTW), and refractive outcomes in terms of preoperative reserved diopters(PRD)and actual equivalent spherical diopters(AESD). The patients were divided into two groups by age(≤7 and >7 a), AL(<23 and ≥23 mm)and WTW(≤11.5 and >11.5mm), and the diopter errors between their AESD and PRD predicted based on the measurement results were compared.RESULTS: The patients comprised 9(75%)boys and 3(25%)girls. Two(17%)patients had anterior subcapsular cataracts, 4(33%)had posterior polar cataracts, and 6(50%)had nuclear cataracts. The mean age at cataract extraction was 6.4±1.61(3.4-8.9)mo. The mean interval between cataract extraction and secondary IOL implantation was 6.8±1.82(4.4-11.5)a. The mean preoperative BCVA was 0.49±0.33(1.0-0.1)LogMAR. The mean postoperative BCVA was 0.38±0.32(1.0-0.0)LogMAR. The mean AL was 23.56±1.96(19.00-26.38)mm, and the mean WTW was 11.5±0.92(9.3-13.9)mm. The mean PRD was 1.57±0.60(0.73-2.77)D, the mean AESD was 0.57±0.55(-0.50 to 1.75)D, and the mean difference between the AESD and PRD was -0.99±0.52(-2.22 to 0.32)D. The differences in the AESD and PRD between the groups according to age, AL and WTW were not statistically significant(P=0.59, 0.56, and 0.53, respectively).CONCLUSION: IOL implantation in the ciliary sulcus after a modified incision is safe and feasible for children with aphakia. It is necessary to subtract approximately 1 D of IOL power from the formula-selected power when implanting an IOL in the ciliary sulcus. Age, AL, and WTW do not significantly affect the difference.

Objective:The treatment of head and neck in plexiform neurofibroma (PNF) is a major clinical problem, lacking consensus on surgical treatment, classification, operation timing, and treatment method. The purpose of this study was to provide a basis for further consensus formation by analyzing the clinical manifestations, surgical conditions, tumor recurrence, post-operation satisfaction, and changes in quality of life of patients undergoing PNF surgery in head and neck.Methods:Through medical record review and telephone follow-up, a retrospective analysis was conducted on neurofibromatosis type 1 (NF1) patients admitted for surgical treatment for PNF patient in head and neck from May 2012 to July 2022 in Department of Plastic and Reconstructive Surgery, Shanghai Ninth People’s Hospital, Shanghai Jiao Tong University School of Medicine. Complete collection and statistical analysis of patients’clinical data, using telephone follow-up to investigate the immediate postoperative satisfaction and long-term surgical satisfaction of patients and/or their families, as well as standardized quality of life questionnaires HRQol(health related quality of life) and PlexiQol(plexiform neurofibroma quality of life). Based on the data about changes in quality of life before and after surgery and long-term surgical satisfaction, patients were divided into surgical benefit and non-benefit groups. Binary and multivariate logistic regression analysis were used to analyze the clinical characteristics of patients with long-term surgical benefit.Results:Totally 512 patients with head and neck NF1 were admitted for surgery with complete medical records. 121 patients were identified as NF1 related PNF diagnosed by medical history and radiological examination, and effective follow-up was obtained. There were 70 males and 51 females, aged (25.60±12.85) years old, ranging from 7 to 63 years old, with 41 patients who were ≤ 18 years old and 80 patients over 18 years old. 62.81%(76/121) of patients exhibiting clinical dysfunctions, and the tumor mass were mainly characterized by invasive growth. 41.32%(50/121) of patients underwent multiple surgical treatments, with a total of 215 surgeries performed on 121 patients. The surgical objective included appearance improvement and functional repair. The incidence of postoperative complications was 6.05%(13/215). The follow-up period after last operation was (51.41±27.66) months, and 42.15%(51/121) of patients reported postoperative tumor recurrence. 76.03%(92/121) of patients were satisfied with immediate postoperative result, while the rate decreased to 46.28%(56/121) during long-term follow-up. Family members of patients who were ≤ 18 years old had a higher proportion of dissatisfaction with the scars caused by surgery and a stronger willingness to undergo another surgery. The tumor recurrence was closely related to surgical benefits ( OR=2.32, P<0.05). Further analysis found that the gender and age of patients were the main risk factors for the recurrence. The recurrence risk in patients ≤ 18 years old was significantly higher than in that over 18 years old( OR=3.49, P=0.004), and the highest in the 7-12 year-old group, reaching 68.42%(13/19). The recurrence risk in male patients was significantly lower than that in females ( OR=0.40, P=0.026). Conclusion:The clinical manifestations of PNF patients in head and neck region are complex. Clinical diagnosis and treatment in PNF should focus on the applications in comprehensive method such as full preoperative evaluation, active multi-disciplinary treatment cooperation and combined therapies in order to improve the safety and effectiveness of treatment and reduce tumor recurrence.

AIM:To explore the modulation of 2-arachidonoylglycerol(2-AG)on A-type potassium channels injured by kainic acid(KA)and its molecular mechanism.METHODS:Primary cultured caudate nucleus(CN)neurons were treated with KA to establish a neuroexcitatory toxicity model.Whole-cell patch clamp recording was performed to ob-serve the changes of electrical activity of A-type potassium channels induced by KA-induced excitatory toxicity and 2-AG-mediated neuroprotective effect.RESULTS:In cultured CN neurons,patch clamp experiments confirmed that KA signifi-cantly decreased the A-type potassium channel current(IA)density and changed the electrical function of CN neurons:the slope(k)of inactivation curve and the recovery time constant(τ)after inactivation of A-type potassium channels in CN neurons were significantly increased.The experiments showed that the increase in 2-AG level,whether using 2-AG direct-ly or application of monoacylglycerol lipase inhibitor URB602 to decrease 2-AG metabolism and increase 2-AG level indi-rectly,inhibited the KA-induced reduction of IA density and the changes of electrical activity of A-type potassium channels through cannabinoid receptor 1(CB1R):2-AG effectively antagonized the KA-induced increases in τ value and k value for inactivation of A-type potassium channels,which accelerated the recovery process after inactivation of the channels.CONCLUSION:The changes of the electrical characteristics of A-type potassium channels may be one of the mecha-nisms of KA-induced excitotoxic injury of CN neurons.The 2-AG plays a neuroprotective role in KA-induced neuroexcit-atory toxic model by regulating the function of A-type potassium channels through CB1R.
