Status quo and correlation between readiness for discharge and quality of discharge teaching in lung cancer patients based on enhanced recovery after surgery / 中国胸心血管外科临床杂志

@#Objective    To explore the current situation of the readiness for hospital discharge and the quality of discharge teaching in lung cancer patients based on enhanced recovery after surgery, and to analyze their correlation. Methods    We conducted a cross-sectional study and 141 postoperative patients with lung cancer in our hospital from July to August 2018 were investigated by general information questionnaire, readiness for hospital discharge scale and quality of discharge teaching scale. There were 65 males and 76 females at age of 18-85 (55.35±12.15) years. Results    Totally 88.65% of postoperative patients with lung cancer reported that they were ready for discharge, and the total score of readiness for hospital discharge was 78.36±16.48, and the total score of quality of discharge teaching was 90.94±18.62. There was a positive correlation between the readiness for hospital discharge and the quality of discharge teaching in postoperative patients with lung cancer (r=0.57, P<0.01). Conclusion    The readiness for hospital discharge of postoperative patients with lung cancer keeps in medium level, while the quality of discharge teaching is good, and the readiness for hospital discharge is positively correlated with the quality of discharge teaching. Medical staff should pay more attention to the cognitive level of lung cancer patients' disease-related information and their physical function recovery, and enrich the discharge guidance content, in order to improve the readiness of postoperative patients with lung cancer.

Determination of contact angle of pharmaceutical excipients and regulating effect of surfactants on their wettability / 药学学报

To study the effects of surfactants on wettability of excipients, the contact angles of six types of surfactants on the surface of two common excipients and mixture of three surfactants with excipients were measured using hypsometry method. The results demonstrated that contact angle of water on the surface of excipients was associated with hydrophilcity of excipients. Contact angle was lowered with increase in hydrophilic groups of excipient molecules. The sequence of contact angle from small to large was starch < sodium benzoate < polyvinylpyrrolidone < sodium carboxymethylcellulose < sodium alginate < chitosan < hydroxypropyl methyl cellulose <magnesium stearate. In addition, surfactants both in droplets and mixed in excipients significantly reduced the contact angle of excipients, and their abilities to lower contact angle varied. The results of the present study offer a guideline in the formulation design of tablets.
