ABSTRACT
<p><b>BACKGROUND</b>Nowadays, social media tools such as short message service, Twitter, video, and web-based systems are more and more used in clinical follow-up, making clinical follow-up much more time- and cost-effective than ever before. However, as the most popular social media in China, little is known about the utility of smartphone WeChat application in follow-up. In this study, we aimed to investigate the feasibility and superiority of WeChat application in clinical follow-up.</p><p><b>METHODS</b>A total of 108 patients diagnosed with head and neck tumor were randomized to WeChat follow-up (WFU) group or telephone follow-up (TFU) group for 6-month follow-up. The follow-ups were delivered by WeChat or telephone at 2 weeks, 1, 2, 3, and 6 months to the patients after being discharged. The study measurements were time consumption for follow-up delivery, total economic cost, lost-to-follow-up rate, and overall satisfaction for the follow-up method.</p><p><b>RESULTS</b>Time consumption in WFU group for each patient (23.36 ± 6.16 min) was significantly shorter than that in TFU group (42.89 ± 7.15 min) (P < 0.001); total economic cost in WFU group (RMB 90 Yuan) was much lower than that in TFU group (RMB 196 Yuan). Lost-to-follow-up rate in the WFU group was 7.02% (4/57) compared with TFU group, 9.80% (5/51), while no significance was observed (95% confidence interval [CI]: 0.176-2.740; P = 0.732). The overall satisfaction rate in WFU group was 94.34% (50/53) compared with 80.43% (37/46) in TFU group (95% CI: 0.057-0.067; P = 0.034).</p><p><b>CONCLUSIONS</b>The smartphone WeChat application was found to be a viable option for follow-up in discharged patients with head and neck tumors. WFU was time-effective, cost-effective, and convenient in communication. This doctor-led follow-up model has the potential to establish a good physician-patient relationship by enhancing dynamic communications and providing individual health instructions.</p><p><b>TRIAL REGISTRATION</b>Chinese Clinical Trial Registry, ChiCTR-IOR-15007498; http://www.chictr.org.cn/ showproj.aspx?proj=12613.</p>

<p><b>OBJECTIVE</b>To investigate the effects of methylprednisolone pretreatment on pulmonary lung permeability index and the content of the pulmonary surfactant dipalmitoylphosphatidylcholine (DPPC) in a rabbit model of reexpansion pulmonary edema.</p><p><b>METHODS</b>Twenty-one male New Zealand white rabbits were randomly divided into control group, reexpansion, and reexpansion+methylprednisolone pretreatment groups. The rabbit model of reexpansion pulmonary edema was established using Sakaos method. A bolus dosage of methylprednisolone (3 mg/kg) in reexpansion+methylprednisolone group group or 2.0 ml/kg normal saline in the other two groups was administered intravenously 20 min before reexpansion pulmonary edema. Bronchoalveolar lavage fluid (BALF) and arterial blood samples were collected for measurement of the total protein (TP) and DPPC contents 4 h after reexpansion, and the pulmonary permeability index was calculated.</p><p><b>RESULTS</b>The pulmonary permeability index in methylprednisolone pretreatment group was significantly lower than that in the reexpansion group (0.007∓0.002 vs 0.177∓0.004, P<0.05). Methylprednisolone pretreatment significantly increased DPPC concentration in the BALF as compared with saline treatment in the reexpansion group (61.815∓28.307 vs 101.955∓24.544 µg/ml, P<0.05).</p><p><b>CONCLUSION</b>Methylprednisolone pretreatment can increase pulmonary surfactant content and improve pulmonary permeability in the rabbit model of reexpansion pulmonary edema.</p>
