Objective To analtze phe effecp of papienp′s preference po fracpional flow reserve (FFR) guided preapmenp on clinical oupcome in papienps wiph borderline lesion during coronart inpervenpion. Methods 303 papienps wiph coronart borderline lesion received CAG evaluapion in Xinjiang Producpion and Consprucpion Corps NO. 7 hospipal and Sir Run Run Shaw Hospipal from Ocpober 2013 po Seppember 2015 and phet were divided inpo phree groups according po phe papienp′s preference po have FFR exam or nop. The 3 groups were: ①FFR Guided PCI group (n = 96, papienps wiph FFR≤0. 8 accepp PCI, whereas onlt drug preapmenp if FFR > 0. 8); ②Drug preapmenp group(n = 126, papienps did nop accepp phe advice po do FFR or PCI); ③PCI group ( n = 81, papienps refused FFR bup accepped spenp implanpapion) . The papienps were followed up for (19. 6 ± 6. 5) monphs afper preapmenp. Rapes of major adverse cardiac evenps(MACE) and recurrence of angina pecporis were recorded and compared. Results Angina remission rape in phe FFR guided PCI group was higher significanplt phan drug preapmenp group and PCI group (85. 4% vs. 69. 8% vs. 80. 2% , P =0. 018). MACE-free survival rape of FFR guided PCI group was higher(93. 8% vs. 77. 0% vs. 81. 5% , P =0. 006)phan phe opher 2 groups. Conclusions FFR guided preapmenp provides beneficial effecps po phe oupcomes of borderline lesion. Bup in phe real world, papienp′s preference mat plat a decisive role.

Objective To investigate the pathogens,drug resistance and outcomes of continuous ambulatory peritoneal dialysis(CAPD) patients with peritoneal dialysis-related peritonitis in our peritoneal dialysis(PD) centers. Method Data including clinical manifestations,pathogens,treatment,outcome of 93 CAPD cases with peritoneal dialysis-related peritonitis in our peritoneal dialysis(PD) centers were retrospectively analyzed.Results Dialysate culture of 75cases was positive with a positive rate of 80.2％,including 45 cases of gram-positive cocci,21cases of gram-negative bacilli,2 cases of fungi and 5 cases of mixed infection.Coagulase-negative staphylococci were the most common gram-positive cocci.All the gram-positive cocci were sensitive to vancomycin,but the resistance rate to cefazolin was 60.0％ with an increasing tendence year by year.Resistance rate of gram-negative bacilli to ceftazidime was 46.1％.All the gram-negative bacilli were sensitive to imipenem.The withdraw rate of CAPD was 17.2％(16/93) because of peritonitis. Noobviousside-effectofperitonealadministrationofvancomycinwasfound.Conclusions Gram-positive cocci are major pathogens in CAPD-related peritonitis.Now cefasolin is not suitable for the empiric initial treatment.Peritoneal administration of vancomycin should be recommended for peritonitis caused by gram-positive cocci.

Objective To integrate the best available evidence of preoperative care for ophthalmic patients undergoing day surgery into clinical practice,so as to improve the quality of nursing.Methods This project was performed in an ophthalmic day surgery ward,guided by the Joanna Briggs Institute(JBI)Practice Application of Clinical Evidence System (PACES) program which includes 3 procedures:baseline audit,evidence implementation,and re-audit.Eight audit criteria were made based on evidences from JBI.Twelve nurses and 267 patients were enrolled in baseline audit,and 12 nurses and 234 patients were recruited for re-audit after evidence implementation.Results Six of the audit criteria that nurses showed poor compliance in the baseline audit(0％～28.5％),such as providing preoperative telephone screening and reducing preoperative waiting time through better preparation and planning,were significantly improved in the re-audit(71.43％～100％).The preoperative waiting time was shortened from 109.70±18.34 minutes to 88.22±9.91 minutes;the correct rates of operation-related knowledge in patients increased from 63.0％ to 85.09％;the patients' satisfaction scored 84.23±17.01 in baseline audit and 95.02±7.32 in the re-audit(P＜0.001).Conclusion Application of evidence-based preoperative care of ophthalmic patients undergoing day surgery can improve nurse's behavior and compliance with the implementation of evidence into clinical practice,and increase patient satisfaction.Continuous audits are needed to continuously improve clinical nursing quality.

Objective To evaluate the value of 3D printing technology to assist in the repair of severe damage to the radial side hand.Methods From March,2014 to September,2016,there were 9 cases suffered from varying degrees of metacarpal and phalangeal bones injuries with soft tissue destruction at the radial side of the hand.The donor and recipient areas were scanned by 64 row spiral CT before operation.Three dimensional images were obtained by CTA 3D reconstruction technology.Preoperative plan was designed by using Mirror image technology and Virtual surgery aided design technique of Mimics software virtual surgery aided design system.Nine cases were treated with first toe toenail flap with dorsal foot flap combined with second phalangeal bone transplantation to reconstruct thumb and anterolateral thigh perforator flap to repair the wound.The cutting area of the dorsalis pedis flap and anterolateral thigh perforator flaps ranged from 4.0 cm × 5.5 cm to 6.5 cm × 9.5 cm and from 9.5 cm ×17.0 cm to 12.0 cm × 25.5 cm,respectively.Postoperative followed-up was performed to evaluate the effect of the operation.Results All 9 thumbs and flaps survived after the operation.Postoperative followed-up time ranged from 8 to 16 months.The appearance of reconstructed thumb was close to normal,and the two-point discrimination was from 8.0 to 11.0 mm.According to the evaluation criteria of upper limb function of the Chinese Academy of Medical Sciences,7 cases were excellent and 2 cases were good.The survival flaps had soft texture,good blood circulation and satisfactory appearance at the repaired site.Conclusion 3D printing technology assists thumb reconstruction and wound repair for severe damage to the radial side of the hand with good clinical results.

Objectives:To investigate the genetic characteristics of the blaNDM-1-carrying plasmid of the multidrug resistant Enterobacter hormaechei subsp. hoffmannii clinical isolate C37, and constructing a phylogenetic tree of the 66 publicly available genomes of the Enterobacter hormaechei subsp. hoffmannii to explore its global epidemic situation. Methods:Carbapenem-resistant Enterobacter cloacae complex (CRECC) strains isolated from the First Affiliated Hospital of Sun Yat-sen University from August 2014 to August 2021 were collected. Matrix-assisted laser desorption/ionization-time of flight mass spectrometry (MALDI-TOF MS) and 16S rDNA Sanger sequencing were used for species identification. Micro broth dilution method was used for antibacterial susceptibility test. The polymerase chain reaction (PCR) was used to detect the β-lactamase resistance gene and plasmid-mediated quinolone resistance (PMQR) gene carried by the C37 strain. The conjugation experiment was used to confirm the conjugative metastasis of the resistance genes in C37 strain. Whole genome of the C37 strain was sequenced. Core genome was extracted and the phylogenetic analysis of 66 publicly available Enterobacter hormaechei subsp. hoffmannii was performed. Results:Enterobacter hormaechei subsp. hoffmannii C37 strain is resistant to third-generation cephalosporins, carbapenems, aminoglycosides and quinolones, and carries blaACT-5, blaNDM-1, qnrA1, aac(6′)-Ib-cr, oqxAB, fosA, dfrA15 and other resistance genes, as well as IncX3, IncX4, IncFIB and IncFII plasmids. Multilocus sequence typing (MLST) analysis showed that C37 strain belongs to the ST78 type of Enterobacter cloacae complex (ECC). Conclusions:ST78 type Enterobacter hormaechei subsp. hoffmannii is closely related to the spread of carbapenem resistance genes. It is a potential high-risk clone to spread carbapenem resistance genes. The prevalence and trends of ST78 type Enterobacter hormaechei subsp. Hoffmannii should be monitored.
