Objective:To establish the sensitive quality indicators for cardiovascular nursing based on the RAND Corporation University of California, Los Angeles (RAND-UCLA) expert consensus method, so as to lay the foundation for scientific and standardized quality management of cardiovascular nursing.Methods:Relevant literature was searched on China National Knowledge Infrastructure, WanFang Data, VIP, China Biomedical Literature Database, Cochrane Library, PubMed, EMbase and CINAHL. The search period was from database establishment to August 31, 2021. We used the Johns Hopkins evidence-based nursing practice model for evidence-based analysis and summary, and referred to documents on cardiovascular nursing quality indicators to form an indicator pool. From May 23 to July 12, 2022, 17 experts were selected to apply the RAND-UCLA expert consensus method to inquire about the indicators.Results:The effective response rates of the first and third rounds of the questionnaire were both 100.00% (17/17) , and the authority coefficients of the experts were 0.87 and 0.88, respectively. Among the 18 indicators in the third round of expert consultation, the consistency degree of importance and operability of all indicators was less than 1.00. Finally, 18 sensitive quality indicators for cardiovascular nursing were established.Conclusions:The consistency and coordination of experts in this study are good, and the nursing sensitive indicators formed have scientific characteristics, cardiovascular specialty characteristics, and good operability.

Objective:To compare the clinical efficacies of Da Vinci robotic and laparoscopic total mesorectal excision (TME) for low rectal cancer.Methods:The retrospective cohort study was conducted. The clinicopathological data of 64 patients with low rectal cancer who were admitted to the Third Xiangya Hospital of Central South University from October 2015 to January 2019 were collected. There were 42 males and 22 females, aged from 40 to 84 years, with a median age of 59 years.

Objective To investigate the correlation between synovial inflammatory changes (synovial blood signals,synovial thickness,joint effusion) and cartilage injury,meniscus prominence of knee osteoarthritis (KOA) under energy Doppler ultrasound and further to assess the value of ultrasound for prognostic judgment in KOA.Methods A total of 291 KOA patients from our hospital from 2016 to 2018 were collected.The patients with rheumatoid arthritis (RA) with knee joints involved were recruited as control group.The data that conform to the normal distribution were expressed by mean±SD,and others were represented by M (P25,P75).The t test,the rank test and Chi-square test were used between the two groups,and ANOVA or K-W test was used to compare the data between the multiple groups,Spearman correlation analysis was used for correlation analysis.Results ① The proportion of synovial blood flow signal in KOA group was lower than RA group (19.6％ vs 47.7％,x2=286.2,P＜0.01),as well as the typical synovial thickness [2.6(0,3.95) mm vs 3.43 (1.85,6) mm,Z=-3.674,P＜0.01] and popliteal cyst (11.5％ vs 18.5％,x2=4.484,P=0.04).② In KOA group,no significant difference was found between ESR and hs-CRP among different synovial blood signals (H=7.213,H=0.883,all P＞0.05).ESR from KOA group were both significantly lower than controls but the synovial blood signals was the same except for power Doppler signal-2 group (Z=-8.414,Z=-4.991,t=-3.428,all P＜0.05);hs-CRP from KOA group were both significantly lower than controls but the synovial blood signals was the same.③ A total of 489 knee joints were detected in 291 patients with KOA,of which synovial blood flow signals were found in 96 joints,the power Doppler signal-I group was the most frequent in KOA (80/96,83.3％).In addition,joint effusion and synovial thickening were positively correlated with the synovial blood signals,(r=0.277,r=0.411,all P＜0.05).④ At last,the degrees of ultrasound blood flow signal in KOA group was positively associated with the WOMAC score,the Lequsne index and US-1 score (r=0.352,r=0.424,r=0.59,all P＜0.05).Conclusion Energy Doppler ultrasonography can be used to detect the KOA synovitis.Synovitis is not rare in KOA patients,and which is associated with disease activity.However,KOA and RA cannot be differentiated by energy Doppler ultrasonography.

Objective To analyze the risk factors of renal replacement therapy (RRT) in acute kidney injury (AKI) patients after liver transplantation, and to investigate the prognosis effect of initial RRT treatment time. Methods Clinical data of 132 recipients undergoing organ donation for cardiac death (DCD) allograft orthotopic liver transplantation admitted to Ningbo Medical Center Lihuili Hospital and Ningbo Medical Center Lihuili Eastern Hospital from July 2014 to July 2018 was retrospectively analyzed. AKI was defined and staged by the criteria of Kidney Disease Improving Global Outcomes (KDIGO) guideline in the first 7 days. According to the implementation of RRT, the patients were divided into non-RRT group and RRT group. The differences in gender, age, body mass index (BMI), model for end-stage liver disease with serum sodium (MELD-Na) score, serum creatinine (SCr), and intraoperative norepinephrine (NE) dose, blood loss, fluid infusion, anhepatic phase time, duration of operation between two groups were compared. The statistically significant risk factors of AKI found by univariate analysis were selected and analyzed to find independent risk factors of RRT in AKI patients after liver transplantation with multivariate Logistic regression analysis. The receiver operating characteristic (ROC) curve was drawn to evaluate the test efficiency of all risk factors of RRT implementation. According to the implementation of RRT on KDIGO stage-2, all the patients on KDIGO stage-2 and stage-3 were divided into early group (initial RRT on KDIGO stage-2) and delayed group (including self-improvement without RRT on KDIGO stage-2 and initial RRT on KDIGO stage-3). The duration of mechanical ventilation, the length of intensive care unit (ICU) stay, AKI duration, incidence of catheter related bloodstream infection (CRBSI) and 28-day mortality were compared between the two groups. Results All 132 receptors were enrolled in the final analysis, and 77 patients developed AKI, accounting for 58.3%, among which 52 cases were in RRT group (67.5%) and 25 were in non-RRT group (32.5%). As shown by univariate analysis, the MELD-Na score (21.6±4.4 vs. 18.0±4.3), intraoperative NE dose (μg·kg-1·h-1: 7.5±1.2 vs. 5.2±1.7), blood loss [mL: 3 000 (2 200, 4 000) vs. 2 600 (1 800, 3 200)], fluid infusion [mL: 6 400 (4 500, 7 800) vs. 5 600 (4 200, 6 800)], and anhepatic period (minutes: 65.6±4.5 vs. 63.0±5.0) were significantly increased in RRT group as compared with those in non-RRT group (all P < 0.05). There was no significant difference in gender, age, BMI, SCr before operation or the duration of operation. It was shown by multivariate Logistic regression analysis that MELD-Na score before operation [odds ratio (OR) = 1.398, 95% confidence interval (95%CI) = 1.062-1.841, P = 0.017], intraoperative NE dose (OR = 4.724, 95%CI = 2.036-10.961, P = 0.000) and fluid infusion (OR = 1.002, 95%CI = 1.001-1.004, P = 0.010) were independent risk factors of RRT implementation in AKI patients after liver transplantation. It was shown by ROC curve analysis that the area under the ROC curve (AUC) of MELD-Na score, NE dose and fluid infusion for predicting the implementation of RRT in AKI patients after liver transplantation was 0.719, 0.867, and 0.670, respectively, which suggesting that NE dose had moderate predictive value, but MELD-Na score and fluid infusion had low predicative value. When the optimal cut-off value of NE dose was 6.5 μg·kg-1·h-1, the sensitivity was 84.6% and the specificity was 80.0%. The 28-day mortality was both 0 in early group (n = 25) and delayed group (n = 39). Compared with the early group, the duration of mechanical ventilation (hours: 41.0±1.0 vs. 35.8±6.7) and the length of ICU stay (hours: 98.8±6.6 vs. 94.2±7.3) were significantly increased in delayed group (both P < 0.05), there was no significant difference in AKI duration (days: 11.8±4.2 vs. 10.6±4.9) or the incidence of CRBSI [5.1% (2/39) vs. 4.0% (1/25), both P > 0.05]. Conclusions MELD-Na score, intraoperative NE dose and fluid infusion were the independent risk factors of RRT implementation in AKI patients after liver transplantation. NE dose had moderate predictive value, but MELD-Na score and fluid infusion had low predicative value. Initial RRT on KDIGO stage-2 could reduce the duration of mechanical ventilation and the length of ICU stay.

Objective To systematically evaluate and analyze the evidence level of randomized controlled trials (RCT) of preoperative skin preparation for emergency percutaneous coronary intervention (PCI), and to understand the current research status and evidence level of preoperative skin preparation randomized controlled trials for emergency PCI, and provide reference for skin preparation for emergency PCI. Methods PubMed, EMbase, The Cochrane Library, CINAHL, JBI, CBM, CNKI, Wanfang DATA were searched by computer from inception to March, 2018 for emergency PCI preoperative skin preparation randomized controlled trials. Two evidence panel members searched and selected articles independently and the quality was assessed in accordance with Cochrane Manual. The articles were analyzed with Review Manager 5.3, and the evidence quality was assessed with GRADE profiler 3.6.1 software. Results A total of 5 RCTs were included, of which the number of RCTs with grade A quality was 1 and the number of RCTs with grade B was 4. The results of the Meta analysis showed that there was no significant difference in the incidence of skin infections at the postoperative puncture site by conventional methods for routine removal of surgical wild hair and no removal of hair prior to emergency PCI (P＜0.05). In addition, regular removal of hair before surgery may result in prolonged preoperative preparation and may cause psychological discomfort to the patient. After the GRADE system rating, the quality of the evidence body was of a lower level. Conclusions It is more beneficial to shorten the treatment time without routine removal of all the hair at the puncture site and the surrounding patients. The evidence included is not yet certain whether the incomplete removal of hair can reduce the infection rate. In the future, more large-scale, multi-center, high-quality research should be carried out to provide more credible evidence for this study.

OBJECTIVETo assess the value of genome-wide high-resolution chromosomal microarray analysis (CMA) for the delineation of pathogenesis for fetal ventriculomegaly diagnosed by ultrasound or magnetic resonance imaging (MRI).

METHODSThree hundred and forty-one cases of fetal ventriculomegaly were collected. The samples were grouped based on the extent of lateral ventricular dilatation, presence of additional features, site of occurrence, and the maternal age. All samples were subjected to karyotyping analysis. For those with a normal karyotype, DNA was extracted and hybridized with an Affymetrix CytoScan HD array. All cases were followed up.

RESULTSAmong the 341 fetuses, 21 (6.2%) were detected with an abnormal karyotype. For the 320 cases with a normal karyotype, 179 (55.9%) have accepted CMA analysis. Potentially pathogenic CNVs were identified in 12 (6.7%) of the 179 cases, whose sizes ranged from 198 kb to 8.71 Mb. These included a 1q21.3q23.1 deletion, a 2q37.3 deletion, a 3p14.1p13 deletion, a 6q25.3 deletion, a 8q11.23 duplication, a 10q21.1 deletion, a 15q11.2 deletion and a 16p13.11p12.3 duplication, a 22q13.33 duplication, a 22q11.21 duplication and a Xp21.1 duplication (Duchenne muscular dystrophy). Pathogenic CNVs were detected respectively in 7.5% and 3.1% of those with mild and severe ventriculomegaly (P=0.615), in 6.1% and 7.4% of those with isolated and non-isolated ventriculomegaly (P=0.732), in 5.6% and 7.9% of those with unilateral and bilateral ventriculomegaly (P=0.511), and in 6.7% of both elderly and non-elderly groups (P=1.000).

CONCLUSIONThe detection rate for abnormal karyotypes among fetuses with ventriculomegaly was 6.2%. CMA can increase the detection rate by approximately 6.7%. There was no significant correlation between ventriculomegaly and presence of pathogenic CNVs. In clinical practice, fetuses with ventriculomegaly and a normal karyotype should be considered for CMA analysis.

Objective To investigate the accuracy of the plasma DNA concentration in evaluating the prognosis in patients with sepsis.Methods One hundred and sixty patients with sepsis were enrolled as the sepsis group (group SE).Another 109 patients without sepsis hospitalized during the same period served as the control group (group C).The venous blood sample was taken on admission for determination of plasma DNA concentration by polymerase chain reaction,C reactive protein (CRP) concentration by ELISA.APACHE Ⅱ score and SOFA score were evaluated at 24 h after admission.The 160 patients with sepsis were divided into two groups according to the result of prognosis:survival group ( n =103) and death group ( n =57).Results Compared with group C,the plasma DNA concentration,CRP concentration,APACHE Ⅱ score and SOFA score were significantly increased in group SE (P＜0.05).Compared with survival group,the plasma DNA concentration,APACHEⅡ score and SOFA score were significantly increased in death group ( P ＜ 0.05).The areas under receiver operating characteristic (ROC) curves of the plasma DNA concentration was significantly larger than those of APACHE Ⅱ score and SOFA score (0.81(95％ CI,0.74-0.88) versus 0.68(95％ CI,0.60-0.77),or 0.72(95％ CI,0.63-0.82)).Conclusion The plasma DNA concentration can accurately evaluate the prognosis in patients with sepsis.As compared with the plasma CRP concentration,APACHE Ⅱ score and SOFA score,the plasma DNA concentration is more accurate to evaluate the prognosis in patients with sepsis.

Recombinant expression vector pcDNA3-DAFMCP-DP containing human membrane complement regulatory proteins (hCRPs) decay accelerating factor (DAF) and membrane cofactor protein (MCP) cDNA was constructed by using two independent promoters. After transfected into NIH3T3 cells by calcium phosphate-DNA precipitate method, NIH3T3 pcDNA3-DAFMCP-DP transfectants were obtained by G418 selection. Extraneous genes integration was identified by PCR. The co-expression of human DAF and MCP at both mRNA and protein levels was confirmed by using RT-PCR and Western blot analysis. Human DAF and MCP cDNA were integrated into NIH3T3 pcDNA3-DAFMCP-DP genomic DNA after continuous 30 times passages, indicating that NIH3T3 pcDNA3-DAFMCP-DP were stable cell lines. Human C-mediated cytolysis assays showed that NIH3T3 cells transfected stably with pcDNA3-DAF, pcDNA3-MCP, and pcDNA3-DAFMCP-DP were protected from C-mediated damage and co-expressed human DAF and MCP provided more excellent protection against C-mediated attack, which was compared with either DAF or MCP alone. These results suggest that the dicistronic vector could improve the efficiency of multi-gene delivery and benefit the synergic effect of human membrane complement regulatory proteins DAF and MCP.
