Abstract: Objective To investigate the clinical distribution characteristics, drug resistance trends and the carrying of antiseptic resistance gene of Pseudomonas aeruginosa infection in children in Suzhou, in order to provide theoretical basis for the prevention and treatment of Pseudomonas aeruginosa infection in children. Methods The clinical distribution characteristics and drug resistance trends of Pseudomonas aeruginosa isolated from Children's Hospital of Soochow University from 2016 to 2021 were retrospectively analyzed. Forthermore, 101 strains of Pseudomonas aeruginosa were randomly selected to detect the expression of 9 antiseptic resistance genes (qacEΔ1-sul1, qacE, qacEΔ1, qacG, sugE(p), sugE©, emrE, ydgE, ydgF) by polymerase chain reaction. Results Pseudomonas aeruginosa in Soochow University Children's Hospital was mainly isolated from respiratory specimen (47.83%), pus (28.60%) and urine (11.72%); the main departments were intensive care unit(21.45%), general surgery department (15.71%) and respiratory department (12.31%). Patients were mainly aged from 1 month to 1 year old and older than 6 years old (34.31% and 25.38%). The top three drug resistance rates of Pseudomonas aeruginosa were imipenem (11.25%), aztreonam (9.26%) and meropenem (8.02%). Among the 853 strains of Pseudomonas aeruginosa, the drug-resistant strains were mainly from the intensive care unit (58/183), hematology department (33/91), neonatology department (31/96), and there were 57 strains of multi-drug-resistant strains with the detection rate of 6.68%. There were 98 strains (11.49%) of Carbapenem resistant Pseudomonas aeruginosa, and the annual detection rates were 22.06%, 8.40%, 3.60%, 5.67%, 9.85% and 17.20%, respectively. Among the 9 antiseptic resistance genes, the carrying rate of ydgF, sugE© and qacE was 98.02%, 94.06% and 0 respectively. Conclusion Pseudomonas aeruginosa has high resistance to some drugs, so attention should be paid to rational drug use. The carriage rates of of two antiseptic resistance genes exceeded 90%, indicating the need to strengthen research on the mechanism of antiseptic resistance research and rational use of disinfectants

Objective To investigate the set-up error of CR in total body irradiation localization and lung shielding.Methods TOR 18FG software was employed to measure the image quality of images at kV and MV levels.The clinical processes were established and the positioning error was analyzed.Results The low contrast resolution and spatial resolution of MV level images were much worse than those at kV level in the condition of total body irradiation,but the image at MV level could be used to identify the high contrast tissues and employed in total body irradiation.The longitudinal errors were (0.50 ± 1.65) cm for left lung and (1.16 ± 1.56)cm for right lung in A P direction,while (1.12 ± 2.22)cm and (0.41 ± 2.16)cm respectively in PA direction.The errors of lateral were (0.81 ± 1.19)cm for left lung and (0.43 ±1.20)cm for right lung in AP direction,while (0.31 ± 1.64)cm and (0.55 ± 1.49)cm respectively in PA direction.Conclusions Application of CR in total body irradiation could make positioning in treatment much easily and reduce the localization errors.

Objective To investigate the clinical characteristics of pulmonary artery sarcoma (PAS) and pulmonary thromboembolism(PTE), to improve doctors' awareness and the early diagnosis of PAS.Methods The clinical data of 10 PAS cases confirmed with biopsy were retrospectively analyzed,and 10 cases with PTE were selected as control group.Results (1) Main clinical manifestations of the two groups were chest tightness, shortness of breath, intermittent syncope, palpitations, chest pain and cough, and there were no statistical significance differences between the two groups (P＞0.05).(2)There were 2 cases (20.0％) PaO2 ＜80 mmHg in patients with PAS.However, there were 8 cases (80.0％)PaO2 ＜ 80 mmHg in control group.The two groups had statistically significant difference (x2 =7.200, P =0.023).(3) Wells score : the cases with PAS was in low risk (80.0％ and 10.0％),however, the cases of control group was in medium and high risk(90.0％ and 20.0％).The two groups had statistically significant difference (P =0.005, 0.001).(4) The two groups had no statistically significant difference in ECG, UCG, X-ray, lung ventilation/perfusion (P＞ 0.05).(5) There had statistically significant difference in terms of LDH and CRP between PAS and PET group (100％ vs.0, x-2 =10.796,P=0.003;100％ vs.0, x2 =15.000, P =0.000).There was faster ESR in PAS group than control group,and the two groups had statistically significant difference (75％ vs.0, x2=1.400, P =0.011).There was no case of D-Dimer＞500 μg,/L in PAS group, while 10 cases in control group, and the two groups had significant statistical difference (x2 =17.000, P =0.000).(6) There was 1 case (12.5％) with DVT in PAS group, 6 cases (60.0％) in PTE group, and the two groups had significant statistical difference (x2=10.568, P =0.001).(7) The CTPA in PAS group showed filling defect in the main pulmonary artery trunk (85.7％ vs.0) ,left pulmonary artery (85.7％ vs.10.0％) ,right pulmonary artery(100％ vs.10.0％) and both left and right pulmonary artery (85.7％ vs.10.0％), the two groups had significant statistical difference (x2 =13.247, P =0.001;x2 =9.746, P=0.004;x2 =13.388, P =0.000;x2 =9.746, P =0.004).Conclusion PAS and PTE can' t be distinguished from the clinical symptoms, ECG, UCG, X-ray,lung ventilation/perfusion imaging.PAS is easily misdiagnosed as PTE.More attention should be given.PAS can be identified early through the blood gas analysis, hypoxemia,Wells score, LDH, CRP, ESR, D-Dimer, DVT and CTPA.

to observe the infarction volume.Nitrate reductase assay was used to detect the level of NO in brain tissue of the rats.The level of S100βin brain was detected by ELISA method.Results Compared with model group,the brain infarction volumes of the rats 24 and 72 h after cerebral ischemia reperfusion in curcumin group were significantly decreased (P<0.05).Compared with sham operation group,the NO and S100βlevels in the brain tissue 24 and 72 h after cerebral ischemia reperfusion of the rats in model group were significantly increased(P<0.05);compared with model group,the levels of NO in the brain tissue 24 and 72 h after cerebral ischemia reperfusion in curcumin group were remarkably decreased (P<0.05);compared with modee group,the level of S100βin the brain tissue 72 h after cerebral iscemia reperfusion in curcumin group was remarkably decreased (P < 0.05 ). Conclusion Curcumin can significantly reduce the degree of ischemia reperfusion injury in the rats and reduce the levels of NO and S100βin brain tissue,which suggests that the decrease of NO and S100βlevels in brain tissue may be associated with the neuroprotective effect of curcumin.

Objective To explore the effects of guideline-based symptom cluster management program on the severity of fatigue, pain, sleep disturbance and the quality of life in lung cancer patients. Methods A total of 88 lung cancer patients admitted from July 2017 to November 2017 were divided into the intervention group and the control group with 44 cases in each group by the wards. The control group received routine nursing. The intervention group received health education and related skills guidance about symptom management of fatigue,pain and sleep disturbance on the basis of routine. The severity of fatigue, pain, sleep disturbance and quality of life were compared between the 2 groups after 3 weeks intervention. Results After 3 weeks intervention, the scores of fatigue,pain and sleep disturbance in the intervention group were 3.65 ± 0.97, 2.44 ± 0.79, 9.30 ± 2.41 respectively,the scores in the control group were 3.89 ± 1.05, 2.77 ± 0.88, 10.09 ± 1.97 respectively. There was no statistically significant differences in fatigue score (F=1.60,P>0.05),but there were statistically significant differences in pain and sleep disturbance scores between two groups (F=7.83, 5.13, all P<0.05). The scores of quality of life, physical, psychological, social, environmental domains in the intervention group were 52.42 ± 4.71,14.02 ± 2.05, 12.39±2.36, 14.39±2.45, 11.61±1.84 respectively,the control group were 50.77±4.11, 13.31±2.21, 11.89 ± 2.04, 13.65 ± 2.69, 11.92 ± 1.86 respectively. There was no statistically significant differences in scores of psychological and environmental domains (F=0.52, all P>0.05), but there were statistically significant differences in total score, scores of physical and social domains between two groups(F=5.03-6.86, all P<0.05). Conclusion The guideline-based management program could effectively control the deterioration of the severity of fatigue,pain,sleep disturbance and improve patient's quality of life.

Objective:To analyze the correlation between serum glycated hemoglobin (HbA 1c), γ-glutamyltranspeptidase(γ-GT) and intercellular adhesion factor-1 (ICAM-1) levels and cognitive impairment in elderly patients with hyperlipidemia complicated with cardiovascular disease. Methods:In this retrospective cohort study, 158 elderly patients who underwent examination and were diagnosed with hyperlipidemia complicated with cardiovascular disease at Beijing Anzhen Hospital Affiliated with Capital Medical University from January to December 2022 were selected as study subjects. The simple mental state scale (MMSE) was assessed in the subjects in combination with the subject′s level of education. Illiteracy≤17 points, primary school≤20 points, middle school and above≤24 points were classified as cognitive impairment group (67 cases), the rest were were classified into the non-cognitive impairment group (91 cases); and another 50 healthy elderly people who received physical examination in the same period were selected as the control group. The blood samples in the three groups were extracted to measure serum HbA 1c, γ-GT and ICAM-1. The correlation between HbA 1c, γ-GT and ICAM-1 levels with cognitive impairment were analyzed. Results:The serum levels of HbA 1c, γ-GT and ICAM-1 in the cognitive impairment group were all significantly higher than those in the non-cognitive impairment group and the control group [5.41%±1.04% vs 4.82%±0.95%, 4.39%±0.86%; (52.01±10.96) vs (41.28±9.23), (25.03±7.17) U/L; (336.61±85.36) vs (286.93±72.53), (143.52±64.20) g/ml], and the MMSE score was significantly lower [(20.19±2.85) vs (25.30±1.24), (27.14±1.56) points] (all P<0.05). Serum levels of HbA 1c, γ-GT and ICAM-1 were all significantly negatively correlated with MMSE score ( r=-0.512, -0.498, -0.563) (all P<0.05). The areas under the receiver operating characteristic curves (AUCs) for serum HbA 1c, γ-GT, and ICAM-1 levels in the assessment of cognitive dysfunction were 0.657, 0.816, and 0.691, respectively (all P<0.05). The optimal cut-off values were 5.115%, 47.65 U/L, and 304.58 g/ml, respectively. Conclusion:Serum HbA 1c, γ-GT and ICAM-1 levels in elderly patients with hyperlipidemia complicated with cardiovascular disease are negatively correlated with cognitive impairment, and have certain value for the evaluation and early diagnosis of cognitive impairment.
