Objective To investigate the effect of Spiriva Respimat on acute exacerbation of COPD with benign prostatic hyperplasia(BPH). Methods The 167 patients who were hospitalized for acute exacerbation of chronic obstructive pulmonary disease (COPD)(aged 51～96 years) with an average age of (74.26±7.6) years and the 82 patients treated with Spiriva Respimat in the department of respiratory and critical care medicine of our hospital from September 2017 to September 2019 were reviewed. In our pilot study, 48 AECOPD patients with BPH patients were enrolled as the treatment group and another 45 similar cases as the control group. In the former group Spiriva Respimat was administered and the control group was not. Results There were 45 patients (52.94%) with BPH in AECOPD group and 48 patients (58.53%) with BPH in Spiriva Respimat group. There was no statistical significance between the two groups (P>0.05). Among them, 10 patients (11.76%) with AECOPD and BPH had frequent urination and night urination, 4 patients (4.7%) of urinary retention, 16 patients (18.82%) who had oral Harnal and Finasteride, 5 patients (5.8%) need catheterization. In the AECOPD patients with BPH treated with Spiriva Respimat, 7 patients (8.53%) had frequent urination and night urination, 1 patient (1.21%) had urinary retention, 20 patients (24.39%) had oral Harnal and Finasteride, and 3 patients (3.6%) were managed through catheterization (P>0.05). Conclusion Spiriva Respimat does not increase the acute exacerbation of COPD patients with BPH, nor does it increase the use of drugs to treat BPH. It is safe to treat COPD patients with BPH in stable stage.

Methods From December 2017 to December 2018,60 patients with NAFLD in outpatient department and inpatient department of our hospital were selected as observation group,while 60 normal people were selected as control group.The circadian rhythm (dietary pattern,dietary time,activity rhythm,body mass index,sleep rhythm) of the subjects in the two groups were measured by self-made personal data questionnaire,MEQ and smart bracelet.The circadian rhythm characteristics of two groups were compared and the correlation between circadian rhythm and NAFLD was analyzed. Results There were significant differences in BMI,absolute night sleep,moderate night sleep,daily average exercise less than 30 minutes,sleep disturbance,sleep duration and deep sleep time between the patients with NAFLD and the control group (P<0.05). NAFLD was used as dependent variable and circadian rhythm as independent variable. Logistic regression analysis showed that gender,age,nature of work,BMI,sleep rhythm,physical exercise,sleep duration and deep sleep time were positively correlated with fatty liver (OR>1,P<0.01). Conclusion The circadian rhythm of NAFLD patients generally has the characteristics of insomnia,staying up late,irregular sleep time,less exercise and plump figure.The related factors causing NAFLD include BMI,sleep rhythm,motor rhythm,occupational nature,age,gender and sleep quality.In clinic,circadian rhythm intervention therapy may improve the prognosis of patients with NAFLD.

Objective To investigate the autophagy mechanism of bone marrow mesenchymal stem cell-derived microvesicle (BMSC-MV) in repairing premature ovarian dysfunction in rats. Methods The whole bone marrow adherence method was used to isolate,culture and identify BMSCs of SD rats. Microvesicles were isolated from bone marrow mesenchymal stem cell by ultracentrifugation. Premature ovarian insufficiency (POI) model was prepared by intraperitoneal injection of cisplatin solution,and serum estradiol (E2) and follicular stimulating hormone (FSH) were detected by ELISA from tail vein 3 days after preparation. Rat model of POI was treated with BMSC-MV transplantation by tail vein. Blood from tail vein was collected 28 days after transplantation to detect E2,FSH and AMH by ELISA. Meanwhile,ovarian tissues were collected to detect autophagy-related proteins LC3 and P62. Results The E2 content of the model control group and the microvesicle transplantation group was lower than that of the normal control group,and the FSH content was higher than that of the normal control group (P<0.001). The content of E2 and AMH in the microvesicle transplantation group at 28 days after transplantation was higher than that in the model control group (P<0.001),and the content of FSH was lower than that in the model control group (P<0.001). Compared with the model control group,LC3 expression in the microvesicle transplantation group was increased,while P62 expression was decreased (P<0.001). Conclusion BMSC -MV mediate autophagy to repair premature ovarian insufficiency in rats.

Objective To investigate the current status of the first-aid ability of nurses at different levels in outpatient clinics of stomatological hospitals, and to further explore the optimization of the training model of first-aid nurses in outpatient clinics. Methods A total of 97 nurses in our outpatient clinic from January 2019 to January 2020 were selected. The nurses were assessed by self-designed questionnaire surveys and on-site operation skills assessment to investigate the nurses' first aid ability. Results The difference in first aid ability (including relevant knowledge and operation ability) of nurses at different levels in the dental clinic was statistically significant (P<0.05). Among them, the first-aid ability of nursing staff of N1 grade (working 1 ~<3 years) is lower than that of nursing staff of N2 grade (working 3 ~ 5 years). The N3 level (working 6～10 years) first aid knowledge assessment and operation assessment scores are slightly lower than those of working N2 nurses, but the difference is not statistically significant. There was no statistically significant difference in the first aid ability in nurses of different ages, educational backgrounds, titles, and departments. Conclusion The first-aid training of nurses in oral clinics should be conducted in different levels, especially the first-aid skills training of nurses below N1 level. We should be strengthened to ensure the homogenization of nurse's first-aid training effect, which is of great significance to improve medical safety and quality of care in oral clinics.

Objective To investigate the value of Mycoplasma pneumoniae RNA simultaneous amplification and testing(MP RNA-SAT)in the diagnosis and treatment of community acquired pneumonia(CAP) in children. Methods The clinical data of 310 children with CAP were selected for retrospective analysis,including 155 Mycoplasma pneumonia pneumonia(MPP)and 155 non-MPP,and the results of MP RNA-SAT and MP-IgM in both groups were compared. Results With the results of clinical diagnosis as reference, the specificity (97.4%)or positive predictive value (92.2%)by RNA-SAT was higher than that by IgM (72.3% and 74.4%, respectively), while the sensitivity (30.3%)or negative predictive value (58.3%)was lower than that by IgM (80.6% and 78.9%, respectively).The difference was statistically significant (P<0.05). Age>3 years, no macrolide treatment before testing, or choosing bronchoalveolar lavage fluid as testing samples, that can improve the detection rate of RNA-SAT(P<0.05). Conclusion RNA-SAT may specifically identify active infection of MP, and the combined use of RNA-SAT and IgM test may more quickly and accurately diagnose infection of MP.It has high value for the diagnosis and treatment of community acquired pneumonia in children. RNA-SAT should be performed before the application of macrolide treatment as early as possible. If necessary, bronchoalveolar lavage fluid could be chosen as testing samples to improve the detection rate of RNA-SAT.
