Objective To investigate the application effect of APP in continuing care of discharged patients with condylar fracture after operation. Methods By convenience sampling,from September 2016 to March 2017 in a ward of oral and maxillofacial surgery and received surgical treatment of condylar fracture patients 81 cases, randomly divided into observation group (41 cases) and control group (40 cases).On the basis of routine health education,the observation group carried out continuous care by APP, while the control group received routine health education. The opening type, opening degree, occlusion relation and temporomandibular joint pain in two groups were compared at 6 months after discharge. Results The results of 6 months, the patients in the observation group were open type, occlusion and TMJ pain were better than the control group, the opening degree of the observation group was (35.51 ± 4.34) mm, control group was (31.28 ± 4.57) mm, the difference between the two groups was statistically significant(t=-4.28,P<0.05).There was no statistical difference between the two groups of occlusion and temporomandibular joint pain (P>0.05). Conclusions APP can improve the open type, opening and occlusal relation and temporomandibular joint pain in patients with condylar fracture after operation.

Objective:To explore the feasibility of high-flow nasal cannula(HFNC)therapy for respiratory failure in elderly patients.Methods:A total of 300 patients with respiratory failure admitted to Peking University Shougang Hospital from December 2016 to March 2019 were enrolled in this prospective study.Patients were divided into three groups: the HFNC group, the conventional oxygen therapy(COT)group and the non-invasive positive pressure ventilation(NPPV)group(n=100 in each group). Arterial oxygen saturation(SPO 2), oxygen index(OI), heart rate(HR), respiratory rate(RR), mean arterial pressure(MAP), comfort level, discharge rate, tracheal intubation rate, rate of referral to ICU, mortality and rate of referral to another group after therapy were compared between the HFNC and COT groups and between the HFNC and NPPV groups. Results:SPO 2 after oxygen therapy for 30 minutes( t=-2.992, P=0.003), 1 hour( t=-2.884, P=0.005)and 6 hours( t=-3.196, P=0.002)and OI before discharge( t=-2.060, P=0.048)were higher in the HFNC group than in the COT group.The HR in the above two groups was lower before discharge than before therapy, and the HR in the COT group was even lower(73.1±25.1 beat per minute vs.75.1±25.9 beat per minute), but both were within the normal range.The discharge rate was higher( χ2=-1.969, P=0.049), while the rate of referral to another group was lower in the HFNC group than in the COT group( χ2=-3.115, P=0.002). There was no significant difference in the tracheal intubation rate, ICU transfer rate and mortality between the HFNC and COT groups.SPO 2 after oxygen therapy for 30 minutes( t=-2.026, P=0.046)and 6 hours( t=-2.101, P=0.040)were higher in the HFNC group than in the NPPV group, but there was no significant difference in OI and SPO 2 between the two groups before discharge.The HR in both HFNC and NPPV groups was lower before discharge than before therapy, and there was no statistical difference between the two groups.The mortality, discharge rate, tracheal intubation rate, ICU transfer rate and rate of referral to another group had no significant difference between the HFNC and NPPV groups.The comfort level was higher in the HFNC group than in the COT and NPPV groups( t=-3.758 and -19.180, both P=0.000). Conclusions:HFNC is a new type of oxygen therapy equipment introduced after COT and NPPV, and possesses more advantages for elderly patients with respiratory failure.

Hospital culture plays an important role in the orderly operation of large shelter hospitals as well as epidemic prevention and control.From April to May 2022, the shelter hospital of the National Convention and Exhibition Center(Shanghai) had created the large shelter hospital culture co-built by doctors and patients with a greater sense of belonging by taking measures such as joint party building between doctors and patients, giving play to the vanguard force of party members, carrying out various forms of cultural, sports and science popularization activities, encouraging enthusiastic patients to participate in activity planning, focusing on key groups, formulating shelter " residents convention", and so on. These measures ultimately formed cultural adaptation, cultural synchronization and cultural shaping, which were conducive to enhancing the empathy of doctors and patients, improving the effectiveness of medical implementation, and promoting the standardization of shelter management system. This harmonious, warm and autonomous culture co-built by doctors and patients effectively ensures the safe and orderly operation of the shelter hospital, and provides reference for the construction of the cultural system of large shelter hospitals in China.
