Objective To analyze the predictive value of serum micro RNA(miR)-411-5p and micro RNA(miR)-485-5p levels in preeclampsia(PE)pregnant women combined with ultrasound blood flow indicators for perinatal outcomes.Methods A total of 88 pregnant women with PE who were enrolled in the obstetric card and underwent cesarean section in Beijing Nuclear Industry Hospital from January 2020 to December 2021 were selected as the study subjects(PE group).In addition,90 normal pregnant women who delivered by cesarean section due to other reasons in the same period were regarded as the control group.The differences of pulsitility index(PI)and resistance index(RI)were compared between the two groups.The serum levels of miR-411-5p and miR-485-5p were measured and compared between the two groups by real time fluorescent quantitative PCR(qRT-PCR).According to the different perinatal outcomes of PE patients,they were grouped into good outcome group and poor outcome group.The differences of PI,RI,miR-411-5p and miR-485-5p between the two groups were compared.The predictive effect of PI,RI,miR-411-5p,miR-485-5p and combined detection on the adverse perinatal outcome of PE patients was analyzed by the receiver operating characteristic(ROC)curve method.Results The RI(0.79±0.08)and PI values(1.82±0.08)of pregnant women in the PE group were higher than those in the control group(0.66±0.06,1.38±0.15),the serum levels of miR-411-5p(0.32±0.09)and miR-485-5p(0.26±0.03)were lower than those in the control group(1.01±0.08,1.02±0.09),and the differences were statistically significant(t=12.283,24.339,54.091,75.231,all P＜0.001).The RI(0.83±0.08)and PI(1.86±0.09)values of PE patients in the poor outcome group were higher than those in the good outcome group(0.70±0.07,1.71±0.07),the serum levels of miR-411-5p(0.27±0.02)and miR-485-5p(0.24±0.02)were lower than those in the good outcome group(0.45±0.04,0.31±0.04),and the differences were statistically significant(t=11.545,12.428,37.840,14.716,all P＜0.001).The areas under the curve of ultrasound blood flow index RI and PI to predict the adverse perinatal outcome of PE patients were 0.838(sensitivity was 90.8％,specificity was 65.2％),and 0.758(sensitivity was 50.8％,specificity was 91.3％),respectively.The areas under the curve of serum miR-411-5p and miR-485-5p in predicting adverse perinatal outcome of PE patients were 0.830(sensitivity was 90.8％,specificity was 73.9％),and 0.769(sensitivity was 95.4％,specificity was 61.9％),respectively.The area under the curve of the four combined tests to predict the adverse perinatal outcome of PE patients was 0.976(sensitivity was 98.5％,specificity was 91.3％).Conclusion The levels of miR-411-5p and miR-485-5p in serum of PE pregnant women were decreased,and the combination of miR-411-5p and miR-485-5p and ultrasound blood flow indicators PI and RI may predict the perinatal fetal outcome of PE pregnant women.

Selection and measurement of clinical outcome are key components of clinical research in implant dentistry. Shanghai Ninth People′s Hospital, Shanghai Jiao Tong University School of Medicine took the lead and collaborated with multiple internationally renowned colleges of stomatology to develop an international consensus on the core outcome set and measurement in implant dentistry, which took two years and was published in May, 2023 in Journal of Clinical Periodontology and Clinical Oral Implants Research simultaneously. The consensus, aiming at identifying the full spectrum of benefits and harms of interventions, provides a comprehensive, agreed, and standardized set of outcomes that should be measured and reported as a minimum in clinical trials relating with implant dentistry, bone augmentation, and soft tissue augmentation. The present review describes the methodology and key elements of the consensus to help Chinese clinical researchers fully understand and appropriately apply the core outcome set and improve the overall quality of Chinese clinical research in implant dentistry.

To investigate the active compounds from on the heart and brain of mice at simulated high altitude.Fifty healthy male adult BALB/c mice were randomly divided into normal control group, hypoxic model group, acetazolamide group, petroleum ether extract of (PESI) group and octacosan group with 10 mice in each group. Acetazolamide group, PESI group and octacosan group were treated with acetazolamide PESI (200 mg/kg) or octacosan by single tail vein injection, respectively. Except normal control group, the mice were exposed to a simulated high altitude of for in an animal decompression chamber. After the mice were sacrificed by cervical dislocation, the heart and brain were histologically observed by HE staining; superoxide dismutase (SOD) activity, total anti-oxidant capacity (T-AOC) and the content of malondialdehyde (MDA) in plasma, heart and brain tissues were detected by WST-1 method, ABTS method and TBA method, respectively; lactic acid and lactate dehydrogenase (LDH) activity in plasma, heart and brain tissues were detected by colorimetric method and microwell plate method, respectively; ATP content and ATPase activity in heart and brain tissues were detected by colorimetric method. PESI and octacosane significantly attenuated the pathological damages of heart and brain tissue at simulated high altitude; increased SOD activity, T-AOC and LDH activity, and decreased the contents of MDA and lactic acid in plasma, heart and brain tissues; increased the content of ATP in heart and brain tissues; increased the activities of Na-K ATPase, Mg ATPase, Ca ATPase and Ca-Mg ATPase in myocardial tissue; and increased the activities of Mg ATPase, Ca-Mg ATPase in brain tissue. PESI and octacosan exert anti-hypoxic activity by improving the antioxidant capacity, reducing the free radical levels, promoting the anaerobic fermentation, and alleviating the energy deficiency and metabolic disorders caused by hypoxia in mice.

Objective To analyze the status and influencing factors of job satisfaction of nurses at public hospitals, providing references for the teambuilding strategy of nurses. Methods Questionnaire survey method was used, in October 2017, to study job satisfaction of 1,047 nurses at 13 public general hospitals, for a countermeasure study. Results Job satisfaction of the nurses was found at a medium level. Specifically, their overall job satisfaction score was 3. 68, and the satisfaction scores of the following dimensions from high to low were: on-the-job training (3. 91), hierarchical nurse use (3. 79), performance appraisal (3. 68), promotion evaluation (3. 67), and remuneration (3. 62) respectively. Contents of the five dimensions are strongly related to the overall job satisfaction (r＞0. 6). Job satisfaction scores of nurses with their differences in positions, annual income, and hospital level were significantly different (P＜ 0. 05). The three main influencing factors for talent turnover rate are remuneration, workplace pressure and work environment. Conclusions Higher remuneration, improved hierarchical management system, and greater attention to nursing care at secondary hospitals are very important for effectively improving the job satisfaction of nurses and ensuring the health care industry.

Objective To deepen and promote the development of nursing higher education internationalization through the analyzation of the status,existing problems and future trends of research about nursing higher education.Methods Searching literatures in China National Knowledge Infrastructure (CNKI),VIP and WANFANG databases from 1984 until 2014.Results 79 references were selected from 44 journals and the numbers increased each year.69.62％ (55/79) of them were accepted by statistical source core journals and 54.43％ (43/79) of them were funded.The authors came from 19 provinces.There were only 4 articles reported international education about graduates and most of them were about undergraduate students.The main reformation measures included curriculum and english teaching reform et al.Conclusions The educator paid more attention to nursing higher education internationalization than before,also the policy's support and the quality of literatures were optimistic.However,the breadth,depth and integrity of research should be strengthened in future.

Objective To explore the effect of action research based on group learning in hospice care module for nursing students. Methods 82 students were divided into cooperative learning group (40) and conventional teaching group (42). The cognition and attitude of good death questionnaire was used to evaluate teaching effect before and after teaching of hospice care. After teaching, self-feedback and self-feedback questionnaire were made to evaluate the effect of cooperative learning group. SPSS 17 was used to make comparison of data between groups and within groups, and t test, chi square test or Fisher exact probability 2 were also used . Results There were no difference between two groups of nurses before teaching. The students' cognitive level and attitude in cooperative learning group increased significantly, especially their cognitive level of physiological needs (t=5.398, P=0.001), cognition and attitude of death education in intervention group was higher than control group (t=2.992, P=0.004; t=3.661, P=0.001). Although 95% of the nursing students of the cooperative learning group thought group cooperative studying could improve their interests and cultivated their comprehensive abilities, only 50% could accept this kind of studying methods . Conclusions Action research based on group cooperative studying can improve students' cognitive level and attitude of good death, and it is also good for cultivating their ability of au-tonomous learning, innovation, cooperation, and meanwhile, educational action research is a good way to improve both teaching effect and research ability of teacher staffs, but in practice, students' acceptance of group learning needs to be improved.

Objective To investigate the added value of CTAC for improving image quality and diagnostic efficiency of bone imaging in SPECT/CT.Methods Seventy-five patients (47 males,28 females,(56.6± 12.8) years) with abnormal uptake in planar whole-body bone scintigraphy underwent SPECT/CTfor differentiation of malignant from benign spinal lesions.NAC and CTAC SPECT images were classified based on 5-point scale (5:excellent,4:good,3:adequate,2:suboptimal,1:inadequate).The diagnostic confidence for both NAC and CTAC SPECT images were classified based on 4-point scale (4:definite,3:certain,2:equivocal,1:uninterpretable).The pathological results after surgery were used as gold standard to evaluate the added diagnostic value of CTAC for spinal lesions.Wilcoxon-signed rank sum test was used for data analysis.Results CTAC improved the image quality in 37.3％ (28/75) of patients,and downgraded in 2.7％ (2/75) of patients.The remaining 45 patients were unchanged (60.0％,45/75).SPECT with CTAC could significantly improve the image quality (z=-4.747,P＜0.001),but the overall diagnostic confidence was not increased (z=-1.000,P＞0.05).Conclusion CTAC can improve the image quality of spinal SPECT,especially useful in imaging with poorer quality,but it has no significant incremental value in diagnostic confidence.
