Objective To discuss the clinical application value of super selective renal artery embolization-assisted(SRAE-assisted)laparoscopic partial nephrectomy(LPN).Methods A retrospective analysis of the clinical data of patients with stage T1 renal carcinoma,who received LPN,was conducted.The patients were divided into SRAE group(performing LPN without adopting renal hilum vascular clamping)and VC group(performing LPN with adopting renal hilum vascular clamping).The time spent for operation,amount of intraoperative blood loss,and preoperative and postoperative renal functions were compared between the two groups.According to the warm ischemia time(WIT),the patients of the VC group were subdivided into WIT＜25 min subgroup and WIT≥25 min subgroup,and the preoperative and postoperative renal functions were compared between the two subgroups.Results A total of 59 patients with renal carcinoma were enrolled in this study,including 12 patients in SRAE group and 47 patients in VC group.In VC group,WIT＜25 min subgroup had 33 patients and WIT≥25 min subgroup had 14 patients.In both SRAE group and VC group,no patient was referred to open surgery or total nephrectomy.No patient in SRAE group was referred to traditional LPN.The time spent for operation in SRAE group and VC group was 100.50(73.75,132.50)min and 120.00(90.00,145.00)min respectively,the difference between the two groups was not statistically significant(P＞0.05).The postoperative estimated glomerular filtration rate(eGFR)in SRAE group was 100.56(82.85,106.81),which was remarkably higher than 84.66(70.84,94.85)in VC group(P＜0.05).The postoperative serum creatinine level in VC group was 90.50(77.10,104.90)μmol/L,which was strikingly higher than 72.24(65.97,80.27)μmol/L in SRAE group(P＜0.05).The amount of intraoperative blood loss in SRAE group was 50(50,50)mL,which was lower than 50(50,100)mL in VC group(P＜0.05).In VC group,the postoperative eGFR in WIT≥25 min subgroup was 66.13(47.08,82.50),which was lower than 90.80(77.18,98.78)in WIT＜25 min subgroup(P＜0.05).During the postoperative one-year follow-up,no recurrence was observed in both groups.Conclusion Compared with traditional LPN,SRAE-assisted LPN doesn't need to obstruct the renal hilus during surgery,which can avoid the ischemic impairment of the residual renal function and reduce the amount of intraoperative blood loss,moreover,it doesn't increase the operation time,doesn't increase the incidence of complications such as postoperative bleeding,etc.and doesn't affect the curative efficacy and patient's prognosis.

Objective:To conduct a scoping review to analyse the types, performance, advantages and disadvantages of cognitive function assessment tools for ICU patients, to provide a reference for the evaluation of cognitive function in ICU patients in future.Methods:A scoping review study was conducted, literature on cognitive function assessment tools for ICU patients in 9 domestic and foreign databases including China National Knowledge Infrastructure, Wanfang Database, VIP Database, China Biology Medicine disc, PubMed, Web of Science, Cochrane Library, Embase and CINAHL were systematically searched. The search period was from the establishment of the database to May 20, 2024. Literature was independently screened by 2 researchers and relevant information was extracted and summarized.Results:Totally 17 studies were included, with 9 tools for assessing cognitive function in ICU patients, including 6 questionnaires, 1 test battery, 1 assessment software, and 1 telephone interview questionnaire. All of above were generalizable tools, except for the Chinese and English versions of the John-Hopkins Adapted Cognitive Exam as ICU-specific tools. The Mini-Mental State Examination was the most widely used assessment scale.Conclusions:Appropriate assessment tools should be selected according to the specific clinical setting, but there is still a lack of specialized and standardized assessment tools for cognitive dysfunction in ICU patients. In the future, standardized tools which fit our cultural context for evaluating cognitive function in ICU patients should be developed.

Sepsis is a heterogeneous syndrome.It is caused by infections,attributing to immune dysfunction pathologically.The disease is characterized by macrophage-mediated inflammation and immune response throughout its development.During septic development,macrophages metabolize crucially with glycolysis remarkably enhanced.The glycolystic enhancement facilitates septic development by promoting the inflammatory response of macrophages and altering their phenotype.Therefore,direct or indirect inhibition of macrophagic glycolysis can alleviate sepsis and neutralize damages to organs functionally,promoting the polarization of anti-inflammatory phenotype.In this review,we aim to investigate the relationship between macrophagic glycolysis and sepsis,focusing on researching into relevant molecular mechanisms by which glycolysis is regulated for treating sepsis.It is concluded that interfer-ing with macrophagic glycolysis may serve as a novel therapeutic strategy for treating sepsis.

Objective:To investigate the efficacy of hemodiafiltration combined with hemoperfusion in the treatment of secondary hyperparathyroidism (SHPT) in patients undergoing maintenance hemodialysis (MHD).Methods:A total of 40 patients with SHPT undergoing MHD who received treatment at the Blood Purification Center of The First Affiliated Hospital of Anhui University of Science and Technology from February 2021 to March 2023 were included in this prospective cohort study. They were randomly divided into a control group and an observation group ( n = 20/group).The control group received a single high flux hemodialysis, while the observation group used a combination of hemodialysis filtration and hemoperfusion for 3 months. In both groups, the changes in hemoglobin, blood urea nitrogen, serum creatinine, serum calcium, serum phosphorus,and parathyroid hormone levels were compared before and after dialysis. Results:After dialysis, the hemoglobin level in the observation group was (119.45 ± 5.27) g/L, which was significantly higher than (106.30 ± 6.52) g/L in the control group ( t = -7.02, P < 0.001). The serum phosphorus level in the observation group was (1.18 ± 0.17) mmol/L, which was significantly lower than (1.52 ± 0.22) mmol/L in the control group ( t = 5.49, P < 0.001). The parathyroid hormone level in the observation group was (122.14 ± 40.57) ng/L, which was significantly lower than (168.78 ± 78.27) ng/L in the control group ( t = 2.39, P = 0.023). Conclusion:Hemodiafiltration combined with hemoperfusion can reduce clinical symptoms, increase hemoglobin level, and reduce phosphorus and parathyroid hormone levels in patients with SHPT undergoing MHD, which deserves clinical promotion.

OBJECTIVE:To investigate the effect of polyamide on the separation on phenolic acids components by nanofiltra-tion process. METHODS:Phenolic acids components were selected as targets,extracted from the Salvia miltiorrhiza,Lonicera ja-ponica or intermediate preparations (tea polyphenols) with water,and filtered with membranes with different pore sizes. The con-tent changes of components were analyzed by HPLC. RESULTS:Danshensu,protocatechuic aldehyde and caffeic acid could better transmit nanofiltration membranes with 3 different pore sizes;with the decrease of pore size,the rejection rates of neochlorogenic acid,chlorogenic acid,rosmarinci acid,ECG and EGCG grew in different levels. But salvianolic acid B was almost retained by the membrane with low molecular weight except 600-800 Da. CONCLUSIONS:Molecular weight importantly influenced nanofiltra-tion separation on phenolic acid components;nanofiltration has a good prospect in enrichment of phenolic acids components.
