ABSTRACT
Objective:To explore the mechanism of turnover intention of junior nurses after adverse events from three aspects: work pressure, leadership style and personal characteristics.Methods:This study was a cross-sectional survey, using the convenience sampling method, 289 nurses from Shanxi Bethune Hospital from December 2020 to March 2022 were selected as the research subjects, and the general data questionnaire, the Separation Tendency Scale, the Nurses′ Work Stressor Scale, the Service-oriented Leadership Style Scale, and the Prospective Personality Scale were used to survey them.Results:Structural equation model showed that nurses′ job stressor level positively predicted turnover intention, with a path coefficient of 0.74, P<0.01, while service-oriented leadership style and forward-looking personality negatively predicted turnover intention, with path coefficients of -0.60 and -0.37, respectively, both P<0.01. Hierarchical regression analysis showed that both service-oriented leadership style and forward-looking personality negatively moderated the promotion of job stressors on turnover intention, and the moderating effect regression coefficients were -0.146, -0.215, both P<0.01. Conclusions:Hospitals should improve the prospective personality traits of junior nurses and cultivate the service-oriented leadership style of nursing managers after adverse events, so as to reduce the turnover tendency of junior nurses as the second victim, promote the improvement of nursing quality, and stabilize nursing team development.
ABSTRACT
The awake prone position plays an important role in the treatment of hypoxemia and the improvement of respiratory distress symptoms in non-intubated patients. It is widely used in clinical practice because of its simple operation, safety, and economy. To enable clinical medical staff to scientifically and normatively implement prone position for awake patients without intubation, the committees of consensus formulation, guided by evidence-based methodology and Delphi method, conducted literature search, literature quality evaluation and evidence synthesis around seven topics, including indications and contraindications, evaluation, implementation, monitoring and safety management, termination time, complication prevention and health education of awake prone position. After two rounds of expert letter consultation, Expert consensus on implementation strategy of awake prone positioning for non-intubated patients in China (2023) was formulated, and provide guidance for clinical medical staff.

Objective:To investigate the effects of miRNA-30a-5p (miR-30a-5p) and metadherin (MTDH) on the proliferation, invasion and migration abilities of human breast cancer cells in vitro.Methods:The expression of MTDH in cancer and paracancerous tissues of 112 breast cancer patients in the database and miR-30a-5p in cancer and paracancerous tissues of 103 breast cancer patients in the database were analyzed using data from The Cancer Genome Atlas (TCGA) database. Pearson correlation analysis was used to analyze the correlation between miR-30a-5p and MTDH in 1 222 breast cancer patients in the database; the data were updated to August 2022. Breast cancer MDA-MB-231 cells were divided into negative control group (transfected with negative control sequence), miR-30a-5p overexpression group (transfected with miR-30a-5p mimics), siMTDH group [transfected with small interfering RNA against MTDH (siMTDH)], siMTDH+miR-30a-5p overexpression group (transfected with both siMTDH and miR-30a-5p mimics); cell proliferation ability was detected by methyl thiazol tetrazolium (MTT) assay, cell migration ability was detected by cell scratch assay, cell invasion ability was detected by Transwell assay. The relative expressions of miR-30a-5p, MTDH, matrix metalloproteinase (MMP)-2, MMP-9, vimentin and β-catenin mRNA in cells were detected by quantitative real-time fluorescence polymerase chain reaction (qRT-PCR), and the expressions of MTDH, N-cadherin (N-cad), β-catenin, Snail and MMP-9 proteins were detected by Western blotting.Results:In the TCGA database, MTDH expression level was higher and miR-30a-5p expression level was lower in breast cancer tissues compared with paracancerous tissues, and the differences were statistically significant (both P < 0.001). There was a negative correlation between MTDH and miR-30a-5p expressions in 1 222 patients with breast cancer ( r=-0.134, P < 0.001). Compared with the negative control group, the cell proliferation ability was reduced in both siMTDH group and miR-30a-5p overexpression group at 24, 48 and 72 h (all P < 0.001). The cell scratch healing rate in miR-30a-5p overexpression group and siMTDH group was lower than that in negative control group [(61.6±1.6)%, (54.7±5.9)% vs. (80.3±3.0)%] (both P < 0.05). Compared with the negative control group, The number of migrated cells in miR-30a-5p overexpression group and siMTDH group was less than that in negative control group (881±50, 725±63 vs. 1 172±66) (both P < 0.05). Compared with the negative control group, the relative expressions of MMP-2, MMP-9, vimentin and β-catenin mRNA were all down-regulated in MDA-MB-231 cells of miR-30a-5p overexpression group and siMTDH group (all P < 0.05). Compared with the negative control group, the relative expressions of N-cad, β-catenin, Snail and MMP-9 proteins were down-regulated in MDA-MB-231 cells of miR-30a-5p overexpression group and siMTDH group (all P < 0.05). There was no statistical difference in the number of migrated MDA-MB-231 cells between siMTDH+miR-30a-5p overexpression group and siMTDH group (476±5 vs. 389±46, t = 3.37, P = 0.078). There was no statistical difference in the number of migrated cells between siMTDH+miR-30a-5p overexpression group and miR-30a-5p overexpression group (476±5 vs. 477±22, t = 0.02, P = 0.983). Conclusions:The expression of miR-30a-5p is negatively correlated with the expression of MTDH in breast cancer tissues, and either overexpression of miR-30a-5p or silence of MTDH in breast cancer MDA-MB-231 cells in vitro can inhibit cell proliferation, invasion and migration, but MTDH may not be a target gene of miR-30a-5p.
ABSTRACT
Objective:To investigate the psychological status of medical students in clerkship during the outbreak of Coronavirus Disease 2019 (COVID-19), analyze the psychological status characteristics and influencing factors of them, and provide an effective basis for carrying out corresponding mental health education and countermeasures.Methods:The survey was conducted on clerkship medical students in the form of questionnaires, including self-made general status questionnaires, symptom checklist 90 (SCL-90) and social support rate scale (SSRS). Statistical analysis was made on above data, chi-square test was used for rates comparison, t test was for comparison between groups, and Spearman correlation analysis was conducted. Results:The survey obtained 359 valid questionnaires, 18.38% of medical students had different aspects of psychological problems. There was no statistical difference between male and female. For those who knew that there was free psychological counseling for the COVID-19, the levels of three factors, such as compulsive symptoms, anxiety, and hostility, were lower than those of the others who didn't know that [(1.30 ± 0.44) vs. (1.41±0.55), (1.19±0.30) vs. (1.26±0.42), (1.17±0.35) vs. (1.26±0.44), P < 0.05]. SSRS results showed that male students had lower social support availability than female students [(7.46±2.03) vs. (8.10±2.06), P=0.004], and except for somatization, other SCL-90 factors scores of the students were negatively correlated with SSRS scores. Conclusion:During the pandemic, medical students in clerkship have a certain degree of psychological problems, which are negatively related to social support, suggesting that these medical students' mental health can be improved by improving social support.
ABSTRACT
Objective:To introduce how to quickly set up a doctor team to achieve efficient treatment of batchs COVID-19 patients in Changchun GongTi shelter hospital.Methods:A cross-sectional study was conducted to analyze the basic situation of the doctors who supported the Changchun Gongti shelter hospital. The workload is the total number of patients from April 3 to 28, 2022. At the beginning of the task, the first week and the third week of the task, the five point scoring method was used to reflect the doctor's physical and mental state, stress state and rescue achievement. The time phased scheduling and disease grading management were fully implemented after 10 days of operation in the shelter. The doctors' ward round efficiency and self scoring changes before and after the implementation of the plan were compared, and the rescue results were summarized.Results:Total of 56 doctors (the Sichuan medical assistance team to Changchun), who undertook the work of Changchun Gongti shelter Hospital, came from 12 professional departments of 14 hospitals. By internal and external linkage-time phased scheduling and information-based patient zoning and grading management, the admission time of batch patients was shortened from (14.64±10.09) min to (6.80±5.10) min per person( P<0.05), the number of patients that each doctor can view per hour ranges from (28.50±12.26) to (68.43±19.95) ( P<0.01). A total of 1 293 patients were treated. There were no deaths, no accidents and no mild illness to severe illness in shelter hospital. 35 doctors completed a continuous survey. Before and after the implementation of those measures, the average physical state scores and the psychological state scores of doctors improved ( P=0.03), the self-score of stress feeling decreased ( P<0.01), and the self-score of professional achievement increased ( P<0.01). Conclusions:To adapt to the characteristics of emergency treatment for batch COVID-19 patients, the internal and external linkage-time phased scheduling and information-based patient zoning and grading management could help the temporarily convened doctors deal with a large number of patients efficiently, reduce work stress and exposure risk in shelter hospital.
ABSTRACT
Objective To evaluate the value of chromosomal microarray analysis (CMA) for genetic evaluation of fetal ultrasound abnormality. Methods A total of 180 pregnant women with fetal abnormality detected by prenatal ultrasound diagnosis in the first trimester during the period from January 2020 through May 2022 were enrolled as the study subjects. All prenatal fetal screening samples were subjected to G-band karyotyping and CMA. Results G-band karyotyping detected normal karyotypes in 168 samples (93.85%) and abnormal karyotypes in 11 samples (6.15%), and CMA detected 17 positive samples (9.44%) and 163 negative samples (90.56%). The seventeen positive samples included 11 pathogenic copy number variations (CNVs) and 6 variants of unknown significance (VOUS), and there were 11 CMA-positive results consistent with G-band karyotyping, and 6 additional pathogenic CNVs mainly included microdeletion and microduplication syndromes. The detection rates of pathogenic CNVs were 11.11%, 2.63%, 2.78%, 4.00%, 0, 0, 11.11% and 0 among the fetuses with abnormal structure of the cardiovascular system, the lymphatic system, the nervous system, the digestive system, the cranial and face system, the skeletal system, the urinary system, and other system (χ2 =8.188, P = 0.316). All eleven fetuses with pathogenic CNVs detected by CMA were all induced for abortion. Conclusion CMA improves the detection of genetic abnormality among fetuses with ultrasound abnormality in relative to G-band karyotyping, which is feasible for prenatal cytogenetic diagnosis among fetuses with ultrasound abnormality
ABSTRACT
Pseudo subarachnoid hemorrhage (PSAH) is often secondary to resuscitation or severe traumatic brain injury (TBI) and has a high rate of mortality and disability. It is characterized by symmetrical subarachnoid hyper-density opacities on CT scans and is mainly venous reflux disorder caused by diffuse cerebral swelling for various causes. At present, PSAH is primarily examined by CT with reduction of cranial pressure as the treatment method. However, the CT signs of PASH are similar to subarachnoid hemorrhage caused by ruptured aneurysm, so the positive CT screening rate for PSAH is low. Effect of simple reduction of intracranial pressure on prognosis improvement of PSAH patients is also limited. Clinical understanding of PSAH is still insufficient, resulting in missed or false diagnosis and untimely treatment. The authors review the research progress in pathophysiology, diagnosis and treatment methods of PSAH so as to help clinicians better understand PSAH, make early diagnosis and timely treatment and improve patients′ prognosis.
ABSTRACT
Objective:To investigate the clinicopathological characteristics, gene mutation and prognosis of adenoid cystic carcinoma of the breast (AdCC).Methods:A total of 12 cases of AdCC samples archived at Linyi Cancer Hospital from January 2008 to December 2021 were collected, including 8 cases of classic adenoid cystic carcinoma (C-AdCC) and 4 cases of solid-basaloid adenoid cystic carcinoma (SB-AdCC). Histomorphology, immunohistochemicstry and molecular genetics were performed to analyze the clinicopathological characteristics and the prognosis of AdCC.Results:C-AdCC patients grew in the shape of beam-tubuler and cribriform architecture, with characteristic structures of true and pseudoadenoid lumen; SB-AdCC patients grew in nests and solid, with moderate to severe atypia, necrosis and high mitotic count. Immunohistochemistry showed that CK7, CK5/6, p63 and S-100 were expressed in 8 cases of C-AdCC, and CD117 and CD10 were diffusely expressed in 4 cases of SB-AdCC. Fluorescence in situ hybridization (FISH) showed that 3 C-AdCC patients had MYB gene break. Next-generation sequencing (NGS) revealed NOTCH1 gene mutation was detected in 2 SB-AdCC patients. No lymph node metastasis was observed in 8 patients with C-AdCC, but 2 had postoperative lymph node metastasis in 4 patients with SB-AdCC.Conclusions:C-AdCC mainly grows in beam-tubular and sieve shape, with low-grade atypia and good prognosis. Some cases have MYB-NFIB fusion gene. SB-AdCC mainly shows nest-mass, solid growth, moderate to severe atypia, necrosis and mitosis (>5/10 high power field) as well as poor prognosis; some patients have NOTCH1 gene mutation.
ABSTRACT
This paper reported the ultrasonographic findings and pregnancy outcome in a case of fetal cervical aortic arch complicated by premature closure of ductus arteriosus. Ultrasound at 22+6weeks of gestation showed that the apex of fetal aortic arch reached the level of left clavicle, but no obvious abnormality in fetal intracardiac structure was found. Ultrasound examinations showed premature contraction of the fetal ductus arteriosus at 25+ 4 weeks of gestation and premature closure at 27+6 weeks. The pregnant woman was hospitalized due to the aggravation of fetal right heart failure at 34+1 gestational weeks and delivered by cesarean section at 34+3weeks. After 17 d of intensive care, the newborn was discharged in good condition. Ultrasound examination performed three months after birth showed that the aortic arch was at the level of left clavicle and the right cardiac system recovered well.
ABSTRACT
Objective To investigate the effect of miR-148a on the chemosensitivity of cervical cancer HeLa cells to cisplatin and its related mechanism. Methods Cervical cancer HeLa cells were cultured in vitro and the concentration gradient of cisplatin was set to detect IC20 value. Control group, mimic control group, miR-148a mimic group, inhibitor control group and miR-148a inhibitor group were set up. qRT-PCR was used to detect the expression of miR-148a and STAT3 mRNA after transfection. After 4 μmol/L cisplatin treatment, the proliferation of HeLa cells was detected by MTT assay; the apoptosis and cell cycle distribution were detected by flow cytometry; Western blot was used to detect the protein expression of p-STAT3/STAT3, CyclinD1, Bcl-2, Bax and Cleaved caspase-3. Results The IC20 of cisplatin on HeLa cells was about 4 μmol/L. Compared with the mimic control group, the level of miR-148a in the miR-148a mimic group was significantly increased, and the level of STAT3 mRNA was significantly decreased (P < 0.05). Compared with the inhibitor control group, the level of miR-148a in HeLa cells in miR-148a inhibitor group was significantly decreased, and the level of STAT3 mRNA was significantly increased (P < 0.05). On the basis of cisplatin treatment, compared with the mimic control group, the apoptosis rate, G0/G1 phase cell ratio, the protein levels of Bax and Cleaved caspase-3 were significantly increased in miR-148a mimic group, while OD value, the proportions of cells in S and G2/M phase, the protein levels of p-STAT3/STAT3, CyclinD1, Bcl-2 were significantly decreased (P < 0.05); compared with the inhibitor control group, the above indicators of HeLa cells in miR-148a inhibitor group changed significantly in the opposite direction (P < 0.05). Conclusion MiR-148a could enhance the chemosensitivity of cervical cancer HeLa cells to cisplatin by targetedly inhibiting STAT3.
ABSTRACT
Objective:To explore the progression of paroxysmal nocturnal hemoglobinuria (PNH) during pregnancy and treatment for improving maternal and infant outcomes.Methods:Nine pregnant women with PNH were admitted to the Obstetrics Department of Peking University People's Hospital from September 2010 to September 2020. The clinical data of these patients were retrospectively collected and analyzed. Relevant literature was reviewed to summarize the progression, treatment, complications, perinatal outcomes, and follow-up of PNH during pregnancy. Descriptive methods were used for statistical analysis.Results:Among the nine patients, six were classic PNH, and three combined with bone marrow failure disease. Eight cases received blood transfusion/low-dose corticosteroids or combination therapy during pregnancy, and four of them were also received anticoagulants. In seven out of the eight patients diagnosed prenatally, the disease worsened during pregnancy. Complications were noted in eight patients during pregnancy, including fetal growth restriction in seven cases, hypertension and premature delivery in four cases each, thrombosis and intrauterine fetal death in one case each. No maternal deaths were reported, with a live birth rate of 8/9 between 33-38 gestational weeks, with the median at 37 weeks. The median time of postpartum follow-up was 50 months (4-92 months), during which the patients' conditions were all stable, and no abnormalities were found in the growth and development of the babies.Conclusions:Pregnant women with PNH tend to worsen with an increased incidence of perinatal complications and adverse outcomes. Multidisciplinary management is recommended for this population may help improve maternal and infant outcomes.
ABSTRACT
Objective:To explore the symptom experience of patients with acute coronary syndrome before diagnosis, in order to improve their early recognition ability, timely medical treatment rate and formulate relevant measures to provide reference.Methods:Semi-structured interview was performed in 18 patients with acute coronary syndrome from August 12 2020 to September 8 in Shanxi Provincial people′s Hospital using phenomenological research, and the data were analyzed under the guidance of symptom experience model.Results:A total of four themes were summarized: symptom perception: diseases being easily predicted, symptom experiences being diverse and diseases being easily overlooked; symptom evaluation: correct evaluation and evaluation bias; symptom response: self-response and family-society support; reflection on the process of symptom experience:medical behaviour and lack of awareness of disease.Conclusions:At present, the identification of acutecoronary syndrome is still a challenge. Patients should enrich relevant knowledge, pay attention to their own symptom experience, make the correct evaluation and deal with it effectively. Medical workers should carry out relevant education to improve the ability of patients to identify diseases.
ABSTRACT
Objective:To explore the effect of individual rehabilitation intervention on the clinical outcome of patients with acute decompensated heart failure.Methods:A total of 152 elderly patients with acute decompensated heart failure in a tertiary hospital from January 2017 to December 2018 were selected and randomly assigned to the test group and the control group. The test group developed individualized interim rehabilitation interventions based on the evaluation results of balance, mobility, muscle strength and endurance of patients. The control group only performed routine rehabilitation related health care and discharge follow up, the short physical performance battery and the rate of all-cause readmission 6 months after discharge were compared between the two groups.Results:Finally, 144 patients finished the reseach, 72 patients in each group. After 3 months of intervention, the total scores of balance test, 4-meter timed walking, time to complete 5 chair rise and SPPB in the test group were 3.05±1.01, 3.74±0.58, 2.75±0.76, 9.44±2.16, while those in the control group were 2.82±0.86, 3.30±1.02, 2.24±0.74, 8.33±2.46. There was significant difference between the two groups ( t value was from -5.287 to -2.001, P<0.01) . Six months after discharge, the all-cause readmission rate was 12.5% (9/72) in the test group and 23.6% (17/72) in the control group, the difference was statistically significant ( t value was -0.348, P<0.05). Conclusions:The individual rehabilitation exercise based on the results of physical function evaluation can effectively improve the patients' body function and quality of life. Besides this, it can reduce the rate of all-cause readmission 6 months after discharge, which can provide reference for the transitional rehabilitation training of the elderly patients with acute decompensated heart failure.
ABSTRACT
Objective:To analyze the effect of CD100 to monocyte cytotoxicity in non-small cell lung cancer (NSCLC) patients.Methods:Thirty-five NSCLC patients and thirteen healthy controls were included from Zhengzhou Central Hospital between March 2018 and September 2018. Peripheral blood mononuclear cells (PBMC) and bronchial alveolar lavage fluid (BALF) (both tumor site and non-tumor site) was collected from NSCLC patients, while PBMC was collected from healthy controls. Monocytes were purified from PBMC and BALF. Membrane-bound CD100 (mCD100) and CD72 expression on monocytes was measured by flow cytometry. Monocytes from NSCLC patients were stimulated with recombinant human CD100, anti-CD72, matrix metalloproteinase 14(MMP14), or anti-CD100, and were co-cultured with NCI-H1882 cells for 48 h. Tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), granzyme A, granzyme B level in the supernatants, CD16 expression on monocytes, and percentage of target cell death was assessed. Student t test or paired t test was used for comparison. Results:There were no significant differences of peripheral CD14 + mCD100 + percentage, CD14 + CD72 + percentage, CD100 mean fluorescence intensity (MFI), CD72 MFI between NSCLC patients and healthy controls ( P>0.05). CD14 + mCD100 + percentage, CD14 + CD72 + percentage, CD100 MFI, CD72 MFI was remarkably elevated in tumor site compared with in non-tumor site in NSCLC patients ( P<0.05). There was no remarkable difference of peripheral monocytes-induced NCI-H1882 cell death between NSCLC group and control group [(13.95±3.16)% vs (13.22±2.40)%, P=0.451]. Lung-resident monocytes-induced NCI-H1882 cell death was reduced in tumor site when compared with non-tumor site [(11.61±2.81)% vs (14.19±3.57)%, P=0.008 7]. TNF-α, IL-1β, granzyme A, granzyme B level was also decreased in the supernatants of monocytes from tumor site compared with non-tumor site in NSCLC patients( P<0.05). However, there was no statistical difference of CD16 level between two groups( P=0.666). Recombinant human CD100 stimulation promoted NCI-H1882 cell death induced by monocytes from tumor site when compared with unstimulated cells ( P<0.000 1). TNF-α, IL-1β, granzyme A, granzyme B level was also increased ( P<0.05). However, Monocytes, which were pretreated with anti-CD72, induced decreased NCI-H1882 cell death and TNF-α, IL-1β, granzyme A, granzyme B secretion in response to recombinant human CD100 stimulation ( P<0.05). Recombinant human MMP14 stimulation decreased CD14 + mCD100 + percentage and increased soluble CD100 (sCD100) level. NCI-H1882 cell death and TNF-α, IL-1β, granzyme A, granzyme B level was elevated when compared with unstimulated cells ( P<0.05). Anti-CD100 administration decreased sCD100 level. NCI-H1882 cell death and TNF-α, IL-1β, granzyme A, granzyme B level was elevated when compared with MMP14 stimulated cells ( P<0.05). Conclusions:CD100 shedding was insufficient in tumor infiltrating monocytes in NSCLC patients, leading to decreased cytotoxicity. MMP14 might elevate cytotoxicity of tumor infiltrating monocytes via promoting CD100 shedding and sCD100 formation.
ABSTRACT
Objective:To investigate and analyze the effect of ubiquitin-editing protein A20 on monocytes activity in patients with ventilator-associated pneumonia (VAP).Methods:Twenty-four VAP patients (VAP group) and twelve healthy controls (control group) were included from the First Affiliated Hospital of Zhengzhou University between February 2019 and September 2019. Peripheral blood mononuclear cells (PBMCs) and bronchial alveolar lavage fluid (BALF) (both infection site and non-infection site) were collected from VAP patients, while PBMCs were collected from healthy controls. A20 level in CD14 + monocytes were measured. CD14 + monocytes and CD4 + T cells were purified from VAP patients. CD14 + monocytes were transfected by A20 siRNA. Transfected CD14 + monocytes were directly/indirectly co-cultured with autologous CD4 + T cells. The secretion of interferon-γ (IFN-γ) and interleukin-17 (IL-17) by CD4 + T cells was investigated. Transfected CD14 + monocytes were directly/indirectly co-cultured with NCI-H889 cells. Cytotoxicity, and cytokines/granzyme B level, and tumor necrosis factor-related apoptosis inducing ligand (TRAIL)/Fas ligand (FasL) level was assessed. Student t test or SNK-q test was used for comparison. Results:VAP group had elevated percentage of circulating CD14 +A20 + cells than control group [(66.14±19.62)% vs. (52.52±13.71)%, P<0.05], and also had increased A20 mean fluorescence intensity (MFI) than control group [(268.0±72.56) vs. (197.4±60.01), P<0.05]. The percentage of CD14 +A20 + cells in BALF from infection site was higher than from non-infection site in VAP group [(66.14±19.62)% vs. (52.52±13.71)%, P<0.05], while A20 MFI in infection site was also up-regulated compared with non-infection site [(268.0±72.56) vs. (197.4±60.01), P<0.05]. In direct contact co-culture, A20 siRNA transfected CD14 + monocytes, which were purified from peripheral blood and BALF of VAP patients, induced elevated percentage of IFN-γ and IL-17 secreting CD4 + T cells than un-transfection or control siRNA transfection ( P<0.05). However, there were no significant differences of CD4 +IFN-γ + or CD4 +IL-17 + percentages among un-transfection, control siRNA transfection, and A20 siRNA transfection ( P>0.05). A20 siRNA transfected CD14 + monocytes, which were purified from peripheral blood and BALF of VAP patients, induced increased target cell death in both direct and indirect contact co-culture than un-transfection or control siRNA transfection ( P<0.05). Tumor necrosis factor-α, IL-6, granzyme B level and TRAIL MFI was also up-regulated ( P<0.05). There was no remarkable difference of target cell death between direct and indirect contact co-culture ( P>0.05). Conclusions:A20 was increasingly expressed in monocytes of VAP patients, and might dampen the activity of monocytes.
ABSTRACT
Objective:To explore the effect of continuous improvement of emergency procedures in different departments on reperfusion and prognosis of patients with acute ST segment elevation myocardial infarction after chest pain center certification.Methods:From March 2018 to July 2019, the clinical data of 206 patients with acute ST segment elevation myocardial infarction and percutaneous coronary intervention diagnosed in the chest pain center of the Third Affiliated Hospital of Anhui Medical University&Hefei First People′s Hospital were analyzed retrospectively.Ninety-eight patients admitted before certification were set as the control group, and 108 patients admitted after certification were set as the study group.The patients in the study group and the experimental group were compared in terms of the time from the onset to the initial medical contact, the time from the entrance to the implantation of balloon dilation, the time from the initial medical contact to the implantation of balloon dilation, the time of total ischemia and the incidence of major cardiovascular adverse events 30 days after percutaneous coronary intervention.Logistic regression analysis was used to analyze the influencing factors of major adverse cardiovascular events 30 days after operation.Results:Compared with the control group, the time from initial medical contact to implantation of balloon was (84.5 (73.0, 96.0) min), the time of total ischemia was (205.0(159.8, 307.0) min), the time from entrance to implantation of balloon was (72.5(58.3, 83.8) min) in the study group, which was (112.0(93.0, 132.5) min, 241.0(199.0, 329.0) min, 78.0(68.0, 96.5) min was significantly shorter than that of the control group, and the difference was statistically significant (all P<0.05). The time from the onset of disease to the initial medical contact in the study group was slightly shorter than that in the control group(124.5 (77.3, 201.0) min and 130.0 (76.3, 216.0) min), there was no significant difference ( P>0.05). Compared with the control group, the incidence of major cardiovascular adverse events in the study group was lower 30 days after operation (16.7%(18/108) and 28.6%(28/98)), the difference was statistically significant( P=0.040). According to the results of multivariate logistic regression analysis, Killip Ⅲ, Ⅳ ( OR 2.618, 95% CI1.244-5.509, P=0.011), the time from onset to initial medical contact>90 min ( OR 4.562, 95% CI 2.167-9.603, P<0.001), the time from entrance to implantation of balloon>60 min ( OR 2.227, 95% CI1.087-4.563, P=0.029) was an independent risk factor for major adverse cardiovascular events 30 days after operation. Conclusion:The continuous improvement of chest pain center process can promote the rational utilization of medical resources in the region, more effectively shorten the treatment time of myocardial infarction patients, and reduce the occurrence of major cardiovascular adverse events within 30 days after operation.
ABSTRACT
Objective:To investigate the clinical value of plasma N-terminal pro-brain natriuretic peptide(NT-proBNP)and Left ventricular mass index(LVMI )in evaluating the prognosis of elderly heart failure patients with preserved ejection fraction (HFpEF).Methods:From January 2018 to December 2018, 170 patients with heart failure (age≥65years old) in the Third Affiliated Hospital of Anhui Medical University were selected as the subjects of prospective study.According to the left ventricular ejection fraction (LVEF), the patients were divided into two groups: the heart failure with preserved ejection fraction (HFpEF) group (100 cases), the heart failure with reduced ejection fraction (HFrEF) group (70 cases), and the healthy subjects (58 cases) as the control group.Left atrial diameter (LAD), interventricular septum thickness (IVST), left ventricular posterior wall thickness (LVPWT), left ventricular end diastolic diameter (LVEDD), LVEF, left ventricular mass index (LVMI) and plasma NT-proBNP concentrations were compared among the three groups.The study group was followed up for 6 months after standardized treatment to observe the occurrence of major cardiovascular adverse events (MACE). Multiple logistic regression was used to analyze the correlation between the above indexes and the occurrence of mace.ROC curve was used to analyze the predictive value of NT proBNP and LVMI.Results:There were significant differences in LAD, IVSTt, LVPWT, LVEDD, LVEF and LVMI among each group (F value was 110.878, 75.838, 74.044, 137.985, 495.267 and 122.810, respectively, all P<0.001 ). The LAD, IVST, LVPWT, LVEDD, and LVMI in the HFpEF group((40.81 ±4.46) mm, (9.39±1.15) mm, (9.68±1.11) mm, (55.54±3.67) mm, (125.45±19.17) g/m2) were higher than those in the control group ((32.9±3.20) mm, (7.62±0.64) mm, (7.81±0.58) mm, (47.05±3.13) mm, (77.72±11.79) g/m2), and the LVEF was lower than that of the control group ((59.63±5.23)% vs.(67.7±4.35)%) with statistical significance (all P<0.05). IVST, LVPWT, LVEF in HFpEF group( (9.39±1.15) mm, (9.68±1.11) mm, (9.63±5.23)%) were higher than those in HFrEF group ((7.59±1.28) mm, (8.01±1.39) mm, (36.9±7.63 )%) ; and the LAD, LVEDD in HFpEF group ((40.81±4.46) mm, (55.54±3.67) mm) were lower than those in HFrEF group ((45.51±6.1) mm, (64.77±9.55) mm), and the differences were statistically significant (all P<0.05). The plasma NT-proBNP concentration was the lowest in the control group, followed by the HFpEF group and the highest in the HFrEF group(56.0 (30.0, 78.56), 2 624.5 (1 190.5, 5 558.5), 8 528.5 (2 651.0, 21 582.75), F=81.355, P<0.01). Multivariant Logistic regression analysis showed that NT-proBNP and LVMI were independent risk factors for occurrence of MACE in patients with HFpEF( OR=4.796, 95% CI: 2.348-5.127, P=0.035; OR=1.957, 95% CI: 1.810-3.327, P=0.016). ROC curve analysis showed that the area under the curve of cardiovascular adverse events predicted by NT-proBNP and LVMI for 6 months was 0.888(95% CI: 0.825-0.950, P<0.001) and 0.713(95% CI: 0.613-0.812, P=0.013). Conclusion:NT-proBNP and LVMI have important value for prognosis evaluation in elderly patients with HFpEF.
ABSTRACT
Objective:To study the effects of different doses of atorvastatin combined with valsartan on blood pressure variability (BPV) and circadian rhythm in patients with hypertension.Methods:Eighty patients with grade 2 and grade 3 hypertension from March 2018 to March 2019 in Hefei First People′s Hospital were divided into low-dose group (20 mg/d atorvastatin combined with valsartan) and high-dose group (40 mg/d atorvastatin combined with valsartan) according to the random number table method. The efficacy after 8 weeks of treatment was compared between the two groups. The BPV, circadian rhythm, vascular endothelial factors [nitric oxide (NO), endothelin (ET)], serum disease-related factors [human cartilage glycoprotein (YKL-40), soluble intercellular adhesion molecule-1(sICAM-1), folate] and blood lipids [total cholesterol (TC), triglyceride (TG), low density lipoprotein cholesterol (LDL-C), high density lipoprotein cholesterol (HDL-C)] were recorded before treatment and 8 weeks after treatment, and the occurrence of adverse reactions during medicine was counted in the two group.Results:After 8 weeks of treatment, the total effective rate was 97.50%(39/40) in low-dose group and was 92.50%(37/40) in high-dose group, and there was no significant difference in the total effective rate between the two groups ( P>0.05). After 8 weeks of treatment, the 24 h SBPV, daytime SBPV, nighttime SBPV, 24 h DBPV, daytime DBPV and circadian rhythm in the two groups were significantly decreased compared with those before treatment, and the 24 h SBPV, daytime SBPV, daytime DBPV and circadian rhythm in high-dose group were significantly lower than those in low-dose group: (9.53 ± 1.73)% vs. (10.89 ± 1.98)%, (9.14 ± 1.90)% vs. (10.33 ± 2.07)%, (11.56 ± 2.78)% vs. (13.06 ± 3.16)%, (4.78 ± 1.56)% vs. (5.70 ± 1.81)%( P<0.05). After 8 weeks of treatment, the levels of NO, folate and HDL-C in the two groups were significantly increased compared with those before treatment, and the levels with in high-dose group were significantly higher than those in low-dose group: (67.16 ± 13.14) μmol/L vs.(60.53 ± 12.50) μmol/L, (14.94 ± 2.07) mmol/L vs.(13.83 ± 2.28) mmol/L, (1.42 ± 0.15) mmol/L vs. (1.31 ± 0.18)mmol/L ( P<0.05). The levels of ET, YKL-40, sICAM-1, TC, TG and LDL-C in the two groups were significantly decreased compared with those before treatment, and the levels in high-dose group were significantly lower than those in low-dose group: (33.63 ± 5.15) ng/L vs. (37.44 ± 5.13) ng/L, (32.68 ± 6.16) μg/L vs. (36.94 ± 6.03) μg/L, (203.78 ± 41.19) ng/L vs. (249.93 ± 50.81) ng/L, (6.78 ± 1.03) mmol/L vs. (7.38 ± 1.30) mmol/L, (2.88 ± 0.61) mmol/L vs. (3.39 ± 0.85) mmol/L, (3.14 ± 1.05) mmol/L vs. (3.85 ± 1.44) mmol/L ( P<0.05). Conclusions:Different doses of atorvastatin combined with valsartan are effective in the treatment of hypertension, but high dose of atorvastatin combined with valsartan has better effects on blood pressure variability and circadian rhythm, and can effectively improve vascular endothelial function.
ABSTRACT
Objective To analyze the incidence of neonatal glucose-6-phosphate dehydrogenase (G6PD) deficiency in Huangshi area, and to provide guidance for neonatal disease screening. Methods Fluorescence immunoassay was used to detect G6PD activity in an initial screening. Children who were positive in the first screening were recalled for a second screening. Second screening positive children were recalled for G6PD gene testing. Results A total of 105 newborns were positive in the first screening, for a positive rate of 0.21%. A total of 93 cases were recalled, and the recall rate was 88.60%. There were 77 cases positive in the second screening, and the positive rate was 82.80%. A total of 65 patients were recalled, of which 49 neonates were diagnosed, 1 was normal, and 15 refused gene testing. The incidence rate was 0.10%. Conclusion The incidence of newborn G6PD deficiency in Huangshi area is relatively low, which is consistent with the disease distribution trend of “south high-north low”.
ABSTRACT
@#Hypoxia inducible factor-1 (HIF-1) is the main transcription factor and the core regulator for cells to adapt to hypoxia, and oxygen homeostasis is achieved by controlling and utilizing oxygen delivery. Autophagy and apoptosis play an important role in determining cell fate and maintaining cell homeostasis. In recent years, it has been found that the dynamic change of HIF-1 expression plays a key role in the hypoxic adaptive response of cardiomyocytes. The regulation of HIF-1 on autophagy and apoptosis of hypoxic cardiomyocytes determines the survival of cardiomyocytes, which is of great significance for the prognosis of ischemic heart disease.
