AIM: To investigate the feasibility and infection efficiency of MSCs with replication-deficient adenovirus containing delivered gene, and whether enhanced green fluorescence protein (EGFP) gene track the change during rMSCs differentiating neuron-like cells. METHODS: Rat marrow mesenchymal stem cells (rMSCs) were expanded in low density in vitro . Under the control of CMV promoter, pAd-EGFP-Vector was constructed by homologous recombination in E.coil BJ 5183, and the recombinant virus was produced in HEK 293 packaging cell line. rMSCs infected with Ad-EGFP were observed and analyzed with fluorescence microscope. Infection efficiency was assessed by microscopical scoring and flow cytometrics. After withdrawing serum and exposure to ?-mercaptoethanol medium, rMSCs infected with Ad-EGFP was induced to differentiate into neuron-like cells. As a control, the plasmid of pTrack-EGFP also was transfected into rMSCs to evaluate transfection efficiency.RESULTS: The results showed that Adenovirus vector (AdVec) delivered EGFP gene with high efficiency to marrow mesenchymal stem cells. Gene expression analysis showed that 36%?2 % of rMSCs infected with recombinant adenovirus expressed the transgene of EGFP at high levels. However, the transfection of plasmid pTrack-EGFP using routine method of lipofectamin mixed with plasmid DNA (pTrack-EGFP) was not easily successful and the transfection efficiency was much lower. rMSCs infected with Ad-EGFP in different passage could differentiate into typical morphology alike neural cells after withdrawing serum and exposure to ?-mercaptoethanol medium. Immuno-staining with neuron-specific enolase (NSE), a neuronal marker, was strong positive, which suggested that rMSCs infected with Ad-EGFP had the potential to differentiate into neurons or neuron-like cells. CONCLUSION: The AdVec system can deliver target gene into MSCs and EGFP gene carried by AdVec can track the change during rMSCs differentiating into neuron-like cells.

AIM: To construct recombinant adenovirus vector containing brain derived neurotrophic factor, (BDNF) gene using bacterial homogenous recombination, and investigate the expression in expanded rat mesenchymal stem cells (rMSC) in vitro. METHODS: BDNF gene and proBDNF gene were subcloned into adenovirus shuttle plasmid pAdTrack-CMV containing enhanced green fluorescent protein gene (EGFP) expression cassette, forming shuttle vector of pAdTrack-BDNF, and pAdTrack-proBDNF, and co-transformed into BJ5183 bacterial cells with adenovirus backbone vector pAdEasy-1 using chemical transformation. After the recombinant adenovirus vector was obtained, the identified recombinant adenovirus plasmid DNA was digested with Pac I and transfected to 293 cells to package recombinant adenovirus particles. rMSC were infected by recombinant adenovirus and EGFP expression was detected using fluorescent microscope. Infection efficiency was assessed by flow cytometrics. Western blotting identified expression of Ad -proBDNF and Ad-BDNF in rMSC. rMSC infected with Ad -proBDNF and Ad-BDNF were induced to differentiate into neuron-like cells. rMSC infected with Ad -proBDNF and Ad-BDNF were injected into nude mice and assessd in vivo. RESULTS: We successfully constructed the recombinant adenovirus Ad -proBDNF and Ad-BDNF that expressed in expanded rMSC in vitro.CONCLUSION: Recombinant adenovirus high-effectively mediates Ad -proBDNF and Ad-BDNF expression in expanded rMSC in vitro and in vivo.

AIM: To study the effects of cotransplantation of donor-derived bone marrow mesenchymal stem cells on graft versus host disease in a rat allogeneic bone marrow transplantation model. METHODS: Fisher 344 rat bone marrow MSCs were isolated and cultured to the fifth passage (P5) in vitro . The recipient Wistar rats were conditioned with lethal total body irradiation and transplanted with F344 rat bone marrow cells and spleen cells in the presence or absence of (P5) MSCs. The onset time of graft versus host disease (GVHD), incidence of GVHD and survival time were monitored. RESULTS: Cotransplantation of MSCs deferred the onset time of GVHD[(19.1?1.7) d vs (15.6?1.5) d, P

Delirium is an acute cognitive impairment syndrome. The incidence of delirium in intensive care unit (ICU) is higher than that in general wards which is an independent risk factor of clinical outcomes of ICU patients. At present, there is no unified standards in assessment instrument for ICU delirium in China which has influences on early diagnosis and assessment by medical staff and makes the incidence of ICU delirium high. This paper reviewed the research progress of assessment instrument for ICU delirium at home and abroad so as to provide a basis for assessment of ICU patients with delirium in China.

Objective To investigate the current prevention status of hospital acquired venous thromboembolism(VTE) in Shandong province, to further improve the prevention and control of VTE system, and provide reference for prevention of hospital care to improve the quality of VTE. Methods An electronic questionnaire survey was conducted among nurses in 81 hospitals of Shandong province. The questionnaire mainly included three parts:basic information,the current prevention status of hospital acquired VTE and the training needs of nurses. A total of 3 766 valid questionnaires were recovered. Results 59.26%(48/81)hospitals established multi-discipinary team to prevent VTE,76.00%(38/50)of the tertiary hospitals established multi-discipinary team, which was higher than 32.26% (10/31) of the secondary hospitals, the difference was statistically significant (χ2=15.166, P=0.000). The VTE risk assessment scale had been routinely used to assess the risk of VTE in hospitalized patients,80.37%(352/438) tertiary hospital departments implemented grading nursing care while 71.43%(175/245) secondary hospitals departments implemented grading nursing care, the difference was statistically significant(χ2=7.120, P=0.008). Each level hospital mechanical preventive equipment configuration rate was less than 70%.Training needs of nurses:92.11%(3 469/3 766)nurses believed that it was necessary to organize the VTE related knowledge training for nurses,but there were significant differences in the training of nurses with different professional titles (Z=-12.607, P=0.000). 48.04%(1 149/2 392) nurses with junior grade professional titles were not trained. Conclusions The hospital attaches great importance to the prevention of hospital acquired VTE,but the construction level of VTE prevention system is unevenness, and primary hospitals should be further reinforced. The risk assessment scale selection lacks of uniform standards, mechanical preventive equipment allocation rate should to be further improved. And the training of primary nurses should be further strengthened.

Objective? To explore the status quo of nursing masters' core competence and to analyze its influencing factors. Methods? Totally 350 full-time schooling nursing masters from 7 universities from Shandong Province, Guangxi Zhuang Automatous Region, Jilin Province, Yunnan Province, Xinjiang Uygur Automatous Region, Tianjin Municipality and Liaoning Province and 140 nursing teachers from 5 teaching hospitals for nursing masters were selected by convenient sampling between March and October 2018. Nursing masters were investigated with the Core Competence Self-rating Scale for Nursing Masters (CCSRS-NM), while nursing teachers were investigated with the Nurse Master-administered Rating Scale (NMARS). A total of 350 questionnaires were distributed to the master of nursing, 332 valid questionnaires were obtained, 140 questionnaires were distributed to the teachers, and 128 valid questionnaires were obtained. SPSS 17.0 was used for statistical analyses. Multivariate linear regression analysis was employed to explore the influencing factors. Results? The CCSRS-NM score of 332 nursing masters totaled (174.67±23.45); the total NMARS score of 128 nursing teachers was (203.10±26.85). Univariate analysis showed that there were statistical differences in CCSRS-NM scores between nursing masters with different sex, grade, frequent presence at seminars, type of training, time of theoretical learning, published papers or not, attitude to nursing and guidance of supervisors (F/t=2.024, 7.306, 2.375, 2.534, -4.780, 3.792, 11.983, 7.454; P＜0.05); there were statistical differences in NMARS scores between nursing teachers with different age, length of service, professional title, educational background and qualified as supervisors or not (F/t=4.305, 4.696, 6.307, 2.330, -2.226;P＜0.05). According to multivariate analysis, nursing masters' attitude to nursing, time of theoretical learning, guidance of supervisors, sex, published papers or not and grade were the factors influencing nursing masters' core competence (P＜ 0.05); Length of service, professional title and qualified as supervisors or not were the influencing factors to nursing teachers' NMARS scores (P＜ 0.01). Conclusions? The core competence of nursing masters stands at an intermediate level, and nursing teachers' evaluation is higher than nursing masters' self-evaluation. Nursing masters' core competence may be enhanced by strengthening professional attitude education, increasing time of theoretical learning, intensifying supervisors' guidance, encouraging male candidates to study as a nursing major and encouraging nursing masters to publish papers, and reinforcing the communication and exchange between students at different grades. Evaluation of nursing masters' core competence should involve teachers and supervisors with different length of service and professional title.

Objective? To evaluate the impacts of early enteral nutrition (EEN) support and delayed enteral nutrition(DEN) support in the nutritional status and infection complications in patients with severe traumatic brain injury. Methods? The articles of randomized controlled trials about EEN support and DEN support on the nutritional status and infection complications in patients with severe traumatic brain injury were searched in CBMdisc, CNKI, Wanfang Data, VIP, Cochrane Library, Web of Science, PubMed, EMbase from 1990 to 2017. The quality evaluation method in Cochrane-Handbook5.0 handbook was adopted to evaluate the quality of articles and test the heterogeneity of the included articles. Fixed-effect model or random-effect model were used to merge the effects. Results? A total of 10 randomized controlled trials were included. Meta-analysis results proved that, compared with DEN support, EEN support can increase the level of serum total protein, albumin and peripheral lymphocyte count (Z=10.20, 4.23, 5.24;P＜0.01) and reduce the incidence of pulmonary infection and craniocerebral infection in patients with craniocerebral injury (Z=4.12, 2.15; P＜0.05), but it has no effect on the incidence of upper gastrointestinal hemorrhage in patients with craniocerebral injury (Z=0.82, P=0.41). Conclusions? Compared with DEN support (within 48 hours of admission), EEN support (48 hours after admission) can effectively improve serum total protein and albumin, improve nutritional status, increase peripheral lymphocyte count, increase patient resistance and reduce the occurrence of cranial infection and pulmonary infection. Therefore, patients with severe craniocerebral injury should receive EEN support if there is no contraindication.

ObjectiveTo explore the effects of applying multidisciplinary team based action study method in quality control of blood samples before test in order to improve the quality of inpatients' blood samples before test. MethodsA multidisciplinary team which was mainly led by the Nursing Department, professionally guided by the department of Clinical Laboratory and assisted by the Service Center as well as the Information Center was established.

ResultsThe unqualified rate of blood samples had an overall downward trend during the period from August 2017 to August 2018,and there was statistical difference before and after intervention(P＜0.01). ConclusionsMultidisciplinary team collaboration provides guarantee for the improvement of blood samples quality before examination, and the application of action study method regulate the quality of blood samples in each procedure before examination and effectively reduce the unqualified rate of the blood samples.

Objective:To develop the risk assessment scale for deep vein thrombosis (DVT) in Intensive Care Unit (ICU) patients so as to provide a theoretical basis for clinical nurses to assess the risk of DVT in ICU patients.Methods:We drew up the initial entry pool of the scale, and revised the scale through expert letter inquiries. The diagnostic threshold was used to determine with the receiver operating characteristic (ROC) cure, and percentiles were used to determine risk levels. The reliability was analyzed using inter-rater reliability, internal consistency reliability and split-half reliability. The validity was analyzed with the content validity, structure validity and standard correlation validity.Results:The scale included 37 items. The optimal diagnostic threshold of the scale was 10, and the area under the ROC cure was 0.837 with a statistical difference ( P<0.001) . The risk levels of the scale were as follows, 10 to 11 were divided into low risk, 12 to 16 were divided into medium risk, and ≥17 was divided into high risk. The correlation coefficient of the inter-rater reliability of the scale was 0.967 with a statistical difference ( P<0.001) , and the Cronbach's α coefficient and the split-half reliability coefficient of the scale were 0.804 and 0.742 respectively. The content validity of the scale was 0.97, and the standard correlation validity was 0.665 with a statistical difference ( P<0.001) , and the Kaiser-Meyer-Olkin ( KMO) value was 0.533 with no statistical difference ( P>0.500) , and the χ 2 value of the Bartlett sphericity test was 1 849.43 also with a statistical difference ( P<0.001) . The cumulative contribution rate was 65.39%. Conclusions:This study initially developed a risk assessment scale for DVT in ICU patients, which provides a scientific and effective assessment tool for the development of DVT prevention and treatment in ICU patients.
