Rosai-Dorfman disease (RDD) is a benign self-limited disease characterized by lymphadenopathy and phagocytosis of lymphocytes by histiocytes. A case of intracranial-extracranial non communicating RDD was reported in this paper. The patient was admitted to Shiyan Taihe Hospital in May 2020 because of "the left top scalp tumor was found for 4 months, and the right lower limb was numb for more than half a month". The plain scan and enhanced scan of the patient′s head magnetic resonance imaging (MRI) showed that the disease focus of the left parietal bone was slightly uneven enhanced, its internal and external soft tissues were significantly enhanced, and the local internal and external soft tissues were significantly thickened irregularly, with the size of about 3.2 cm× 4.7 cm, and adjacent brain parenchyma was compressed. After resection of left top mass and intracranial mass, pathological results showed spindle cell proliferation with inflammatory reaction, and immunohistochemical staining results supported the diagnosis of RDD. The neurological function of the patient recovered to normal basically 7 months after operation, and no recurrence of the disease was found in the MRI examination of the head. The treatment effect was satisfactory.

Objective:To assess the knowledge of Chinese nurses regarding disaster and emergency preparedness and its related factors.Methods:A total of 1 950 nurses were randomly selected from 152 hospitals of 30 provinces and municipalities in China. Two questionnaires were used to collect general data and associated information. The scale of nurse disaster emergency knowledge includes six dimensions: the function of emergency command system (ICS), the role, triage, communication, special care and isolation decontamination, report and access to important resources, biological agents. All of the data were analyzed with SPSS 20.0.Results:Totally 1 950 valid questionnaires were collected. The average score of Chinese nurses was (147.5 ± 33.8) (index value: 73.75%), which was at a middle level. And it was greater than that of the domestic norm. Among the six dimensions, knowledge of triage yielded the highest score (21.25 ± 5.55) (index value: 85.00%), and knowledge of biologics had the lowest score (10.21 ± 3.00) (index value: 68.07%). Education background, professional title, job position, experience, training and identity also were important associated factors ( t values were -4.107-12.376, P<0.01). Conclusion:Chinese nurses have a moderate level of knowledge of disaster and emergency preparedness. Health administrators should constantly enhance framework for disaster and emergency nursing core competencies, and enrich the content and methods of training. Further, simulation-based training and participation in large-scale disaster relief could improve nurses knowledge of disaster and emergency preparedness.

Objective:To evaluate the inpatient PE incidence and thromboprophylaxis after thoracic surgery according to adjusted Caprini VTE risk assessment model.Methods:The study selected consecutively 500 patients who received thoracic surgery from first of June in consecutive three years of 2015, 2016 and 2017. We retrospectively assessed these 1 500 patients using Caprini VTE risk model and recorded baseline characteristics, postoperative prophylaxis, and PE incidence.Results:Only 19.4% of 2015-year patients received pharmacologic prophylaxis, while the rate reached up to 65.2% in 2016 and 77.2% in 2017. PE occurred on 4 cases in 2015, 1 case in 2016, and 0 case in 2017. The overall incidence of PE was 0.3%(5/1 500). The PE incidence negatively correlated with the implementation of prophylaxis( r=-0.04, P=0.07). The PE risk(odds ratio) increased 4.68 times(95% CI: 0.525-41.800) when patients did not receive prophylaxis in PE cohort. Postoperative pharmacologic prophylaxis with current dosing did not affect the drainage of chest tube after surgery. Conclusion:Implementation of an adjusted Caprini risk assessment protocol can be useful for the thoracic postoperative patients to receive appropriate thromboprophylaxis. Current pharmacologic prophylaxis protocol should be safe and enough to prevent PE after thoracic surgery.

Objective:To investigate the expressions of miR-1254 and its target gene colony-stimulating factor-1 (CSF-1) in glioma tissues and glioma cells, and the effects of miR-1254 and CSF-1 on the proliferation and invasion of glioma cells.Methods:The clinicopathological specimens and paracancerous tissues of 30 patients with glioma who underwent surgical treatment in Shiyan Taihe Hospital of Hubei Province from April 2017 to May 2019 were collected. Quantitative real-time fluorescent PCR (qRT-PCR) was used to detect the expression levels of miR-1254 and CSF-1 mRNA in glioma tissues, paracancerous tissues, U87 cells and human brain normal glial cells HEB. The glioma U87 cells were divided into blank control group, mimic NC group, miR-1254 mimic group, and siRNA NC group, CSF-1 siRNA group. The expression levels of miR-1254 and CSF-1 mRNA were detected by qRT-PCR. The protein expression levels of CSF-1 in each group were detected by Western blotting. Dual luciferase reporter gene assay was used to verify the targeting relationship between miR-1254 and CSF-1 gene. CCK-8 method and Transwell invasion experiment were used to detect the proliferation and invasion ability of cells.Results:The relative expression of miR-1254 mRNA in glioma tissues was 0.44±0.16, that in adjacent tissues was 1.15±0.28, and there was a statistically significant difference ( t=12.914, P<0.001). The relative expression of CSF-1 mRNA in glioma tissues was 1.96±0.27, that in adjacent tissues was 0.98±0.22, and there was a statistically significant difference ( t=14.970, P<0.001). The relative expression of miR-1254 mRNA in glioma cells U87 was 0.39±0.11, that in human brain normal glial cells HEB was 1.03±0.02, and there was a statistically significant difference ( t=10.113, P=0.008). The relative expression of CSF-1 mRNA in glioma cell U87 was 1.02±0.03, that in human brain normal glial cell HEB was 0.32±0.13, and there was a statistically significant difference ( t=9.037, P=0.009). The expression levels of CSF-1 mRNA and protein decreased with the increase of miR-1254 after transfection of miR-1254. The results of dual luciferase reporter gene assay showed that compared with the mimic NC group (1.04±0.12), the fluorescence activity of CSF-1-WT cells in the miR-1254 mimic group (0.31±0.02) was significantly reduced ( t=10.430, P<0.001). The difference in cell proliferation ability among the blank control group (0.71±0.01), mimic NC group (0.68±0.04) and miR-1254 mimic group (0.35±0.01) was statistically significant 48 h after transfection ( F=252.651, P<0.001). The difference was statistically significant between miR-1254 mimic group and blank control group ( P<0.001), and the difference was also statistically significant between miR-1254 mimic group and mimic NC group( P<0.001). The difference in cell proliferation ability among the blank control group (0.71±0.01), siRNA NC group (0.68±0.04) and CSF-1 siRNA group (0.25±0.01) was statistically significant ( F=320.309, P<0.001). The difference was statistically significant between CSF-1 siRNA group and blank control group ( P<0.001), and the difference was also statistically significant between CSF-1 siRNA group and siRNA NC group ( P<0.001). Invasion experiments showed that the difference of transmembrane cells number among the blank control group (365±27), mimic NC group (388±24) and miR-1254 mimic group (83±15) was statistically significant ( F=173.915, P<0.001). The blank control group (365±27), siRNA NC group (404±32) and CSF-1 siRNA group (87±14) had statistically significant difference in the number of transmembrane cells ( F=141.294, P<0.001). Conclusion:The expressions of miR-1254 in glioma tissues and glioma cells U87 are significantly decreased, and the expressions of CSF-1 in glioma tissues and glioma cells U87 are significantly increased. Overexpression of miR-1254 may inhibit the proliferation and invasion of glioma U87 cells by reducing the expression of CSF-1 targetedly.

Objective    To explore an effective and safe drainage method, by comparing open thoracic drainage and conventional thoracic drainage for lung cancer patients after thoracoscopic pneumonectomy. Methods    The clinical data of 147 patients who underwent thoracoscopic pneumonectomy from January 2015 to March 2018 in our hospital were retrospectively analyzed, including 128 males and 19 females. Based on drainage methods, they were divided into an open drainage group (open group) and a conventional drainage group (regular group). The incidence of postoperative complications, chest tube duration, drainage volume at postoperative 3 days, postoperative hospital stay, hospitalization cost and quality of life were compared between the two groups. Results    Postoperative complication rate was lower in the open group than that in the regular group (10.20% vs. 23.47%, P=0.04). The chest tube duration of the open group was longer compared with the regular group (5.57±2.36 d vs. 3.22±1.23 d, P<0.001). The drainage volume at postoperative 3 days was less in the regular group. In the open group, ambulation was earlier, thoracocentesis was less and re-intubation rate was lower (all P<0.001). The postoperative hospital stay in the regular group was significantly longer than that in the open group (8.37±2.56 d vs. 6.35±1.87 d, P<0.001) and hospitalization cost was significantly higher (66.2±5.4 thousand yuan vs. 59.6±7.3 thousand yuan, P<0.001). Besides, quality of life in 1 and 3 months after operation was significantly better than that in the open group (P<0.001). Conclusion    Compared with the regular chest drainage, the effect of open thoracic drainage is better, which can help reduce postoperative complications, shorten the length of hospital stay, reduce the hospitalization cost and improve the quality of postoperative life. It is worthy of clinical promotion.

Objective To evaluate the application effect of the comprehensive weight management mode, RAIDS ( hereinafter shortened as mode RAIDS ) , on patients with first-episode schizophrenia. Methods Totals of 83 patients with first-episode schizophrenia were selected and divided into experimental group, with 40 cases and control group, with 43 cases, according to admission date to the hospital. Patients in the experimental group were intervened according to mode RAIDS, by reviewing on experience, aerobic exercise, intervention on mentality, diet guidance and sleeping management, while patients in the control group were given routine nursing and guidance on physical exercise. The intervention lasted for 3 weeks. Index changes of patients in the two groups before and after the intervention were compared, including Positive and negative syndrome scale ( PANSS) scores, physical features[ body weight, body mass index ( BMI) and waist-to-hip ratio ( WHR) ] , biochemical indexes[ total cholesterol ( TC) , triglyceride ( TG) and fasting blood glucose ( GLU) ] , quality of sleeping[by Pittsburgh sleep quality index (PSQI)], and length of hospital stay. Six months after discharge, mental syndromes, changes in physical features and medication compliance of the patients in the two groups were compared. Results Three weeks after the intervention, compared with the control group, TC, TG and GLU of patients in the experimental group were lower ( P<0. 05 ); 3 weeks and 6 months after the intervention, weight, BMI, WHR, PANSS scores and PSQI scores of patients in the experimental group were lower than those in the control group ( P<0.05);length of hospital stay of patients in the experimental group was shorter than those in the control group, and their medication compliance was higher and detachment rate was also lower in the experimental group (P<0.05).Conclusions RAIDS Mode can effectively promote alleviation of mental syndromes, improve glucolipid metabolism, sleeping quality and treatment compliance of the patients, and control weight gain.

Objective To improve interventional factors and clinical practice by exploring the effect of comprehensive weight management on reviewing, aerobic, intervention, diet guidance and sleeping management ( RAIDS) model in patients with early psychological aberration. Methods This study adopted phenomenological methods of qualitative study. 13 psychological aberration patients′ views on RAIDS model were collected. Results Four concepts including full support, regret, achievement, and positive expectation, were concluded and analyzed from interviews. Conclusions RAIDS weight management model has the function of controlling weight of psychological aberration patients, and it helps patients rebuilt their confidence. It is worth of being spread. Patients should be advised to strengthen oxidant activities. Over expectation of the effect of weight control needs a correct guide from nurses and professional staff. In addition, aimed social support and clearing negative emotion are effective in nursing intervention.

OBJECTIVETo prepare the trimeric subunits of recombinant human mannan-binding lectin (MBL) with biological activities.

METHODSA prokaryotic expression vector containing human MBL N-terminal deletant (rhMBLδN) gene we previously constructed was transformed into E. coli for efficient expression of rhMBLδN fusion protein. Based on the principle that the collagen polypeptides tend to self-assembly into the tertiary structure of proteins by forming a triple helix due to the characteristic properties of the collagen proteins, rhMBLδN fusion protein was limitedly hydrolyzed with thrombin. The obtained rhMBLδN polypeptide was repeatedly dialyzed in 50 mmol/L PBS (pH7.2) and ddH(2)O, and the final product was analyzed for its bioactivities using a ligand-binding assay and a C4d deposition assay.

RESULTSrhMBLδN polypeptide with a relative molecular mass of about 20 000 was obtained by limited proteolysis of rhMBLδN fusion protein with thrombin. Repeated dialyses of rhMBLδN polypeptides in 50 mmol/L PBS and ddH(2)O resulted in the isolation of the trimeric subunit trhMBLδN (with a relative molecular mass of about 50 000), which contained a collagen-like helix. The trhMBLδN protein had a higher ligand-binding activity than rhMBLδN polypeptide, and acquired the activity to initiate the lectin pathway of complement activation, but the activities were lower than those of natural MBL.

CONCLUSIONWe have successfully obtained the bioactive trimeric subunit of rhMBL, trhMBLδN, and this structural subunit is also the functional subunit of the MBL molecule.
