Objective:To identify the core competencies of thoracic surgery specialist nurses and provide a reference for training thoracic surgery specialist nurses.Methods:Following the methodological framework for scoping reviews proposed by the Joanna Briggs Institute, 9 databases were searched from inception to February 23, 2024.Results:A total of 17 papers were included, including 11 papers in Chinese and 6 papers in other languages. By analyzing and integrating the included literature, 6 themes, 15 sub-themes, and 59 entries were identified as the core competencies for thoracic surgery specialist nurses. The themes included direct nursing practice competencies, critical thinking competencies, professional development competencies, interpersonal competencies, managerial competencies, and ethical decision-making competencies.Conclusions:This study reviewed the core competencies of thoracic surgery specialist nurses based on publications worldwide. Combined with the national conditions of nursing development in China, we clarified the core competencies of thoracic surgery specialist nurses that align more closely with the clinical nursing practice in thoracic surgery. In the future, we suggest building a standardized training system based on these core competencies, systematically training thoracic surgery specialist nurses, addressing the challenges in developing core competencies of thoracic surgery specialist nurses, and further improving the quality of thoracic surgery nursing in China.

With continuous improvement of people's living standards, great efforts have been paid to environmental protection. Among those environmental issues, soil contamination by petroleum hydrocarbons has received widespread concerns due to the persistence and the degradation difficulty of the pollutants. Among the various remediation technologies, in-situ microbial remediation enhancement technologies have become the current hotspot because of its low cost, environmental friendliness, and in-situ availability. This review summarizes several in-situ microbial remediation technologies such as bioaugmentation, biostimulation, and integrated remediation, as well as their engineering applications, providing references for the selection of in-situ bioremediation technologies in engineering applications. Moreover, this review discusses future research directions in this area.

Objective:To examine the clinical efficacy of endovascular treatment on symptomatic occlusion of intracranial vertebral artery (ICVA) in early non-acute stage.Methods:Nine consecutive patients who presented with aggressive ischemic events in the early non-acute stage of ICVA occlusion from January 2014 to December 2019 and received endovascular treatment at Department of Neurosurgery, Peking University First Hospital were retrospectively reviewed.There were 7 males and 2 females, aged 63.4 years old(range: 52 to 72 years).The average preoperative modified Rankin scale(mRS) was 4.3(range: 4 to 5), the National Institute of Health stroke scale(NIHSS) was 12.3(range: 8 to 18). Among them, 2 patients received a single stage endovascular treatment, and the other 7 patients received staged endovascular treatment.The strategy of staged treatment was as follows: firstly, the occlusion part was passed through by a micro-guidewire and dilated with balloons to maintain the blood flow above Thrombolysis In Cerebral Infarction grade 2b. Then, the intravascular large load thrombus was eliminated by the fibrinolytic system and strengthened antiplatelet drugs. After that, a second stage of angioplasty with stenting was performed on the severe residual stenosis part.The complications and the recanalization rate were collected, and the National NIHSS and mRS after endovascular treatment and in follow-up period were recorded.Results:In the 2 cases received single stage endovascular treatment, although revascularization was achieved lastly, one patient suffered embolus translocation and the other suffered re-occlusion after mechanical thrombectomy during the operation, respectively.Technical success was achieved in 6 of the 7 patients received staged endovascular treatment.On discharge, the average NIHSS scores was 5.7(range: 3 to 4) of the patients. Three months after operation,the average mRS was 1.6(range:0 to 3) and it was 0.9(range: 0 to 2) at the latest follow-up, which were better than preoperative status.Conclusions:Staged endovascular treatment might be a safe, efficient, viable option in carefully selected patients with symptomatic ICVA occlusion in early non-acute stage. It needs to be confirmed by further investigation, preferably in a large controlled setting.

Objective: To investigate the risk factors of clinically diagnosed acute kidney injury (AKI) patients progressing to acute kidney disease (AKD). Methods: The clinical data of AKI patients admitted to the First Affiliated Hospital of Zhengzhou University from January 1, 2018 to December 31, 2018 were retrospectively analyzed. According to the outcome of the patients, AKI patients were divided into non-acute kidney disease (NAKD) group and AKD group. Clinical characteristics and laboratory data of two groups were compared. The risk factors of AKD in patients with AKI were analyzed by logistic regression, and then the receiver operating characteristic curve (ROC) was drawn to evaluate the predictive value of these risk factors. Results: A total of 254 patients with AKI were enrolled, and 186 patients developed AKD with an incidence of 73.2%. The incidences of AKD in stage 1, stage 2 and stage 3 of AKI were 20.0%, 46.7% and 83.5% respectively. Multivariate logistic regression analysis showed increased peak serum creatinine (within 7 days after AKI diagnosis) (OR=2.561, 95% CI 1.584-4.140, P<0.001), proteinuria (OR=2.952, 95% CI 1.162-7.500, P=0.023) and increased intact parathyroid hormone (OR=1.757, 95%CI 1.104-2.797, P=0.017) were independent risk factors for progression to AKD in patients with AKI. The ROC showed that increased peak serum creatinine (within 7 days after AKI diagnosis) was an important predictor of AKD in patients with AKI (AUC=0.798, P<0.001). Conclusion Increased peak serum creatinine (within 7 days after AKI diagnosis), proteinuria and increased intact parathyroid hormone are independent risk factors for progression to AKD in patients with AKI, providing new evidences and ideas for clinical preventions and treatments of AKD.

Objective: To illustrate the epidemical characteristics of the dog-biting events and molecular evolution of rabies virus (RV) strains prevalent in Shuangbai county of Yunnan province, China. Methods: Epidemical investigation on the dog-biting events and human cases were conducted and the brain tissues of the biting dogs and human cases were sampled post-mortem. Nucleoprotein (N) genes of the RVs were sequenced. Homology and phylogenetic analysis were performed using the relevant bioinformatics software. Results: A total of 12 dog-biting events took place between 2011-2017 in Shuangbai county and 35 persons were bitten. Of the 12 events, 11 were investigated in time and 32 bitten persons received proper wound management and a full post-exposure vaccination course. Rabies has not developed in these wounded cases until now. However, due to failure to receive medical intervention and post-exposure treatment in time, 1 of 3 bitten persons in a single event died of rabies. RV N genes from 5 dogs and 1 person were sequenced. Phylogenetic tree showed that RV strains prevalent in Shuangbai county were closely related with the ones found in neighboring counties/cities such as Chuxiong, Lufeng, Jingdong and Xiangyun. All these strains were related to the ones denoted as clade China-I and prevalent in Sichuan province. Homology analysis showed 99.6%-100% homology in nucleotide and amino acid among the 6 RVs prevalent in Shuangbai county and those prevalent in Chuxiong, Lufeng, Xiangyun and clade China-I of Sichuan province. Compared with the China-I strains prevalent in Chuxiong, Zhaotong and Qujing prefectures between 2006-2007, the homology of nucleotide and amino acid were 97.1%-99.3% and 99.1%-99.6%, respectively. Conclusions Surveillance on the dog-biting events can prevent rabies in humans effectively. RV strains prevalent in Shuangbai county belong to clade China-I and have a close relationship with those of neighboring prefectures, cities, counties and the ones prevalent in Sichuan province.

Objective:To observe the influence of the CD96 and CD71 expressions in the surface of leukemia stem cells (LSC) in the therapeutic effects and prognosis of the children with acute leukemia,and to clarify the relationships between the molecular biological characteristics of LSC in the children with leukemia and their therapeutic effects and prognosis.Methods:Eighty children with acute leukemia were selected as the subjects.Among them, 39 cases were acute lymphoblastic leukemia (ALL) and 41 cases were acute myeloid leukemia (AML).The CD96 and CD71 expressions on the surface of LSC were detected with flow cytometry;the therapeutic effects of the first cycle chemotherapy, the survival rate of 5-year, the incidence of infection after chemotherapy, the recurrence rate after chemotherapy, and the incidence of extramedullary infiltration of the children were observed and compared.Results: The CD96 expression on the surface of LSC was positive in 38 cases (47.5%) and the CD71 expression on the surface of LSC was positive in 45 cases (56.3%);the difference of positive expression rates of CD96 and CD71 was not significant (χ2=1.227, P=0.268).The positive expression rates of CD96 and CD71 on the surface of LSC of the children with AML were significantly higher than those in the children with ALL, and the differences were statistically significant (χ2=22.225, χ2=34.028, P<0.01).The distribution of therapeutic effects and the clinical efficiency of the first cycle chemotherap, in the children with negative CD96 expression on the surface of LSC were superior to those with positive CD96 expression on the surface of LSC;the distribution of therapeutic effects and the clinical efficiency of the first cycle chemotherapy in the children with negative CD71 expression on the surface of LSC were superior than those with positive CD71 expression on the surface of LSC;the differences between two groups were statistically significant (χ2=11.323, χ2=16.589, P<0.05;U=2.939, U=2.291, P<0.05).The survival rate of 5-year in the children with negative CD96 expression on the surface of LSC was higher than those with positive CD96 expression;the incidence of infection after chemotherapy,the recurrence rate after chemotherapy and the incidence of extramedullary infiltration were lower than those with positive CD96 expression.The incidence of infection after chemotherapy and the recurrence rate after chemotherapy in the children with negative CD71 expression on the surface of LSC were lower than those with positive CD71 expression,and the differences between two groups were statistically significant (χ2=5.051,χ2=13.288, P<0.05).Conclusion: The expressions of CD96 and CD71 on the surface of LSC in the children with acute leukemia has relationship with the subtypes of the disease and the therapeutic effects of the first cycle chemotherapy, which can be used as markers for the diagnosis and evaluation of therapeutic effects.The expression level of CD96 is related to the prognosis of the patients, which can be used as an indicator for predicting the prognosis of patients.

Objective To optimize the fermentation conditions for Enterococcus faecalis (E.faecalis) and Saccharomyces cerevisiae (S.cerevisiae) mixed culture.Methods The optimum fermentation conditions for E.faecalis and S.cerevisiae mixed culture were identified by investigating the influence of initial pH,inoculum size,and ventilation rate of the culture broth on mixed microbial growth.Results The optimal initial pH of mixed microbial culture was 7.0 and the inoculation amounts of E.faecalis and S.cerevisiae were 4％ and 10％ respectively,when fermented in 600-mL pilot fermentor (liquid volume 40％) at 30 ℃,with ventilation rate of 0.2 L/min,for 20 h.At the end of the fermentation,the E.faecalis and S.cerevisiae counts were approximately 3.8 × 108 CFU/mL and 2.4 × 108 CFU/mL,respectively.Ventilation for the amount difference of E.faecalis was no significant (P ＞ 0.05),and for the amount difference of S.cerevisiae was statistically significant (P ＜ 0.05).Conclusion The E.faecalis and S.cerevisiae counts increased by 32.2％ and 31.5％ respectively,when the optimized conditions of fermentation culture were used.In this study,high mixed microbial counts were obtained,thus providing a reference for the preparation of large-scale production of mixed microbes.

Chromosomal integration of heterologous genes or pathways is preferred over the use of episomal plasmids for its inherently stability and thus more desirable in the industrial setting. However, the position of integration of heterologous genes in the genome influences the expression levels. In combination of high throughput transformation of the Yeast Knock-out Collection (YKO) and FACS analysis, the position effect on heterologous reporter gene gfp was identified across the whole genome in yeast. In total 428 high-expressed sites and 444 low-expressed sites were spotted, providing massive data to analyze patterns and reasons for region dependency of gene expression on the genome-wide scale.
