Objective:To investigate if injury-related myofibroblast induction could occur in bronchial epithelial cells and the role of TGF-?_1(rhTGF-?_1) in epithelial-myofibroblast transdifferentiation. Methods:Cultured bronchial epithelial cells, 16HBE-14o, were exposed to poly-L-arginine(PLA). Using a immunohistochemical method, ?-smooth muscle actin (?-SMA) expression was detected in those cells after being treated with PLA . Relative activity of chloramphenicol acetyltransferase(CAT) was assessed in 16HBE-14o cells, which were transiently transfected with VSMP8 plasmid containing ?-SMA promoter linked to CAT gene, at different time points after rhTGF-?_1(10 ?g/L) treatment. Results:①?-SMA positive, spindle-shaped cells emerged among the regenerated 16HBE-14o epithelial cells following damage. The number of ?-SMA positive 16HBE-14o cells increased and cell repair was delayed under rhTGF-?_1 stimulation.② CAT activity increased significantly in VSMP8 plasmid transfected 16HBE-14o cells 24 h after TGF-?_1 stimulation.

Objective:To explore the optimal postpartum nursing intervention method of elderly second-birth parturient based on the best evidence and evaluate its effect so as to improve the quality of clinical nursing.Methods:Based on the best evidence obtained from the previous study, the optimal nursing examination index of the elderly second parturient was established, and the evidence of best practice was obtained by using the evidence-based nursing method, and the 2017 revised version (the third edition of) Johns Hopkins evidence-based nursing practice model) was used to guide nurses to apply the evidence to clinical practice. During the period from March to May 2019, the baseline review was completed, including 82 pregnant women and 43 nurses. The evidence was incorporated into clinical practice in June 2019. From July to October 2019, the same indicators and inclusion and exclusion criteria were used to evaluate the effectiveness of evidence application in 43 nurses (including midwives) and 85 elderly second-child parturients in obstetric wards (including baby-friendly areas). The anxiety, depression, maternal satisfaction and nurses' correct implementation rate of the best evidence were compared before and after the application of evidence.Results:After the use of evidence-based intervention, the implementation rate of nurses was above 80%. The anxiety score of parturient decreased from 55.29±10.11 to 41.74±10.35, the difference was statistically significant ( t value was 8.55, P<0.001), and the depression score decreased from 57.77 ±8.32 to 47.86 ±9.33, the difference was statistically significant ( t value was 7.23, P<0.001). Maternal satisfaction increased from 92.68% (76/82) to 98.82% (84/85), the difference was statistically significant ( χ2 value was 3.92, P< 0.05). Conclusion:The result of practice shows that through evidence-based nursing intervention, we can further standardize the postpartum optimal nursing paradigm of elderly second-child parturients in China. Reduce postpartum anxiety and depression and improve maternal satisfaction. And quality review still needs to be continuously promoted and implemented in clinical practice in order to continuously improve the quality of nursing and ensure sustainability.

OBJECTIVE:To provide reference for rational use of narcotics drugs in the clinic. METHODS:A total of 5 841 prescriptions of narcotic drugs in our hospital from Jan. 2012 to Dec. 2013 were selected as subjects. The utilization of drugs was an-alyzed statistically using DDDs,DDC and DUI as index. The situation of pharmacists prescriptions dispensing was analyzed with missing rate of unqualified prescriptions as an indicator. RESULTS:7 narcotics drugs DUI≤1.00 in 2012. 9 narcotics drugs DUIs≤1.00 in 2013. The highest missing rate of unqualified prescriptions was 9.33% in the inpatient pharmacy in 2013. The amount and DDDs of Morphine hydrochloride injection,Morphine sulfate sustained-release tablet and Oxycodone sustained-release tablet all in-creased in 2013,compared to in 2012;DUI of all morphine preparation were >1.00. DUI of Codeine phosphate tablet and Bucin-nazine tablet were decreased from 1.64 and 1.11 in 2012 to 1.02 and 0.74 in 2013,tending to be reasonable. The amount and DDDs of Sulfentanyl injection,Remifentanil injection and Fentanyl patch all in 2013,compared to in 2012. CONCLUSIONS:The utilization of narcotics drugs in our hospital basically tend to be rational,but still many deficiencies exist. We should strengthen in-tervention and management on the the utilization of narcotic drugs further.
