Background and Aims:Single-incision laparoscopic cholecystectomy(LC)has become increasingly popular due to its minimal invasiveness and cosmetic advantages,but challenges remain in biliary identification and limited operative space.Indocyanine green(ICG)fluorescence navigation enables real-time visualization of the biliary tract and may enhance surgical safety and efficiency.This study aimed to evaluate the clinical application value of ICG fluorescence navigation in single-incision LC.Methods:A retrospective analysis was conducted on 59 patients with benign gallbladder diseases who underwent elective single-incision LC at Yixing Hospital affiliated to Jiangsu University from January 2023 to December 2024.Patients were divided into a fluorescence group(n=27)and a white-light group(n=32)according to whether ICG fluorescence navigation was applied.The two groups were compared in terms of Calot's triangle dissection time,operative time,intraoperative blood loss,surgeon satisfaction,hospital stay,and postoperative complications.Results:No significant differences were observed in baseline clinical characteristics between the two groups(all P＞0.05).In the fluorescence group,the cystic duct,common hepatic duct,and common bile duct were all successfully visualized.Compared with the white-light group,the fluorescence group had significantly shorter Calot's triangle dissection time[(25.56±3.49)min vs.(38.81±5.59)min],shorter operative time[(44.67±3.06)min vs.(61.31±4.96)min],and less intraoperative blood loss[(13.44±1.70)mL vs.(14.50±2.11)mL](all P＜0.05),with significantly higher surgeon satisfaction(P＜0.05).No intraoperative bile duct injury,conversion to three-port surgery,or postoperative complications occurred in either group.Conclusion:ICG fluorescence navigation can significantly improve biliary identification efficiency in single-incision LC,shorten operative time,reduce blood loss,and enhance surgeon satisfaction,demonstrating promising clinical application prospects.

Objective:To explore the resistance of common clinical isolates to chlorhexidine gluconate (CHG) and the clinical characteristics of patients with the infections.Methods:A total of 1 000 isolates from the First Affiliated Hospital of Wenzhou Medical University in 2018 (from January to May) were collected, which included 200 strains each of Escherichia coli ( E. coli), Acinetobacter baumanii ( A. baumanii), Pseudomonas aeruginosa ( P. aeruginosa), Staphylococcus aureus ( S. aureus), and Enterococcus spp.. Minimum inhibitory concentration (MIC) of CHG against 1 000 isolates were determined by the agar dilution method. The correlation between the resistance of isolates and clinical characteristics of infected patients was analyzed. Chi-square test or Fisher exact probability test were used for statistical analysis. Results:A total of 57 CHG resistant strains were detected in 1 000 clinical isolates. These CHG-resistant strains were mainly isolated from sputum and intensive care unit ward, accounting for 49.1%(28/57)and 38.6%(22/57), respectively. The resistance rates of P. aeruginosa, A. baumanii, Enterococcus spp., S. aureus, and E. coli to CHG were 16.0%(32/200), 7.0%(14/200), 3.0%(6/200), 1.5%(3/200) and 1.0%(2/200), respectively. The CHG-resistant rates of P. aeruginosa to ceftazidime, ciprofloxacin, levofloxacin and gentamicin were 53.1%(17/32), 78.1%(25/32), 65.6%(21/32) and 50.0%(16/32), respectively, which were all higher than those of CHG-sensitive P. aeruginosa (25.0%(8/32), 25.0%(8/32), 21.9%(7/32) and 15.6%(5/32), respectively), with statistical significance ( χ2=5.317, 18.080, 12.444 and 8.576, respectively, all P<0.05). The hospital mortality was 22.8%(13/57) in patients infected with CHG-resistant bacteria, which was higher than that in patients infected with CHG-sensitive bacteria ((7.0%(4/57); Fisher exact probability test, P=0.018)). CHG-resistant group had a higher history of CHG exposure and antimicrobial treatment (61.4%(35/57) and 70.2%(40/57), respectively), which were both higher than those with CHG-susceptible isolates (17.5%(10/57) and 47.4%(27/57), respectively), the differences were both statistically significant ( χ2=22.947 and 6.118, respectively, both P<0.05). In addition, the multi-drug resistance rate of CHG-resistant strains was 54.4%(31/57), which was higher than that of CHG-susceptible strains (35.1%(20/57)), the difference was statistically significant ( χ2=4.293, P=0.039). Conclusions:CHG resistant strains have higher antimicrobial resistance. Hospital mortality in patients infected with CHG-resistant bacteria is higher than patients infected with CHG-sensitive bacteria. The important risk factors are CHG exposure and antimicrobial therapy.

Objective To explore the Chinese medicine syndrome characteristics of mild cognitive impairment (MCI).Methods The papers of MCI syndrome research were reviewed and collected in China National Knowledge Infrastructure,Wan Fang Data and VIP Data from January of 1990 to December of 2014.Statistical analysis was made on the Chinese medicine syndrome types and syndrome factors.SPSS 17.0 software was adopted to make cluster analysis.Combined with experts' experience,related symptoms to the syndrome factors were carried out.Results Totally 32 papers were included.Mter terminology normalization,there were 24 syndrome types of MCI.Top 5 syndromes with high frequency were syndrome of orifices confused by phlegm,syndrome of deficiency of kidney essence,syndrome of deficiency of both Qi and blood,syndrome of internal exuberance of heat toxin and syndrome of blood stasis blocking brain.In syndrome factors of disease location type,kidney and brain covered the highest proportion,30.83％ and 30.00％.In syndrome factors of disease cause and character types,Qi deficiency covered the most,16.50％.According to results of cluster analysis,combined with experts' experience,15 syndrome factors were extracted,including 69 symptoms.Conclusion Chinese medicine syndrome types of MCI were mainly syndrome of orifices confused by phlegm and syndrome of deficiency of kidney essence.The disease locations were mainly kidney and brain.The disease character was Qi deficiency.

Objective To study the changes of resting-state brain activity in knee osteoarthritis(KOA)patients with chronic pain.Methods The data of 21 KOA patients (KOA group) and 21 healthy controls (HC group) who underwent standard resting-state fMRI scan were analyzed with regional homogeneity (ReHo) method to observe the changes in the patients in contrast to the controls.Results Compared to HC group,patients of the KOA group showed ReHo changes in bilateral frontal lobe,bilateral parietal lobe,bilateral temporal lobe,bilateral cerebellum,limbic system and default-mode network.Conclusion Patients with chronic pain demonstrate abnormal neuron activities in the brain regions, and control loops not only related with pain but also related with emotive function disorder and cognitive impairment.

Objective To explore the methods of improving diagnosis correctness between the patients with prostate cancer and benign prostatic hyperplasia.Methods Totally 87 patients with benign prostatic hyperplasia or prostate cancer which confirmed by MRI and prostate biopsy for the PSA significantly increased in our hospital from July 2013 to March 2016 were collected.By using the three methods of the PI-RADS V2 score,the T2WI+DWI/ADC+DCE-MRI+MRS and PI-RADS V2 score+MRS to diagnose,and comparing with the pathology results,the diagnostic consistency of the two physicians were analyzed.The sensitivity,accuracy and specificity of three ways were compared,and the correlation between PI-RADS V2 score and Gleason score were calculated.Results The diagnostic consistency of the two physicians:PI-RADS V2 score,K=0.951;T2WI+DWI/ADC+DCE-MRI+MRS score,K=0.838;PI-RADS V2+MRSI score,K=0.937.The correlation between PI-RADS V2 score and Gleason score,r=0.871,P=0.001 4;diagnostic sensitivity,specificity and accuracy of PI-RADS V2 score were 77.3％,74.4％,75.9％;diagnostic sensitivity,specificity and accuracy of T2WI+DWI/ADC+DCE-MRI+MRS were 88.6％,76.7％,82.8％;diagnostic sensitivity,specificity and accuracy of PI-RADS V2+MRSI score were 86.4％,81.4％,83.9％,respectively.Conclusion Compared with the traditional diagnostic methods,the combination of new prostate report and data system and MRSI can improve the diagnostic accuracy of prostate cancer and benign prostatic hyperplasia.The PI-RADS V2 score is more objective and accurate in the description of the lesion,but the low signal of benign hyperplastic nodules in transitional zone should be dialogued carefully through a variety of image parameters.
