Objective:To explore the clinical effect of digital endoscopic-assisted one-stage rhinoplasty and septoplasty by using subjective and objective methods.Methods:Thirty-two patients with skeletal crooked nose and nasal septum deviated who underwent endoscopic-assisted rhinoplasty and septoplasty were included in this study from January 2015 to January 2020. This study used objective measurements such as 3D digital imaging technology and CT scans, as well as subjective measurements such as Visual Analogue Scale (VAS), Rhinoplasty Outcomes Evaluation (ROE) scale, Nasal Obstruction Symptom Evaluation (NOSE) and Functional Rhinoplasty Outcome Inventory (FROI-17) to evaluate the crooked nose morphology and nasal respiratory function before and after surgery.Results:Compared with preoperatively, postoperative 3D facial imaging results showed that the deviation distance and deviation angle of the crooked nose were significantly improved (both P<0.05), and the long-term effect of the operation was stable. Subjectively, the patient＇s appearance VAS score and ROE score were significantly higher than those before surgery, while the NOSE score and FROI-17 score of nasal congestion symptoms were lower than those before surgery. Conclusions:Endoscope-assisted one-stage rhinoplasty and septoplasty can achieve the purpose of repairing the nose appearance and improving the nasal respiratory function at the same time. Through a combination of subjective and objective evaluations, our study found that this procedure had the advantages of minimally invasive, stable effect and shorter recover time; meanwhile, this procedure has high patients＇ satisfaction and is worthy of clinical promotion.

Objective:To observe the therapeutic effect of quercetin (QUE) on triggering receptor expressed on myeloid cells (TREM-1) activated macrophage inflammation and lipopolysaccharide (LPS) induced acute lung injury (ALI) in mice, and explore its possible mechanism.Methods:In vitro cell experiment: The primary peritoneal macrophages of mice were collected by intraperitoneal injection of 3% calcium mercaptan acetate. The collected cells were divided into blank control group, dimethylsulfoxide (DMSO) vehicle group, TREM-1 agonist group (10 μg/ml), QUE group (10 μmol/L) and TREM-1 agonist + QUE group (cells were pretreated with 10 μmol/L QUE for 30 min before adding agonist). Enzyme linked immunosorbent assay (ELISA) was used to detect the secretion of interleukin (IL)-1β, tumor necrosis factor (TNF)-α and IL-6 in the culture supernatant of primary macrophages; To observe the effect of QUE on LPS-induced TREM-1 protein levels, macrophages were divided into: normal control group, LPS group (100 ng/ml) and LPS+ QUE treatment group [macrophages were pretreated with 10 μmol/L QUE for 2 hours, and then incubated with LPS (100 ng/ml) for 16 hours]. Western blot was used to detect the expression of TREM-1 protein. In animal experiments: 80 male C57BL/6 mice were randomly divided into 4 groups (20 in each group): normal control group, ALI model group, QUE group and QUE treatment group (LPS+ QUE). In the ALI model group, the ALI model was established by intratracheal injection of 5 mg/kg LPS; The mouse ALI model was established by intratracheal injection of LPS 5 mg/kg in the QUE treatment group, and then intraperitoneal injection of 15 mg/kg QUE. The control group was given the same amount of normal saline intratracheal followed by intraperitoneal injection of DMSO, and the QUE group was given the same amount of normal saline intratracheal followed by intraperitoneal injection of 15 mg/kg QUE. Hematoxylin-eosin (HE) staining was used to observe the pathological changes of lung tissue in each group; Inflammatory cells including IL-1β, TNF- α and IL-6 in bronchoalveolar lavage fluid (BLAF) of mice in each group were counted ; The expression of TREM-1 mRNA and protein in lung tissue of mice in each group was detected by real-time fluorescence quantitative polymerase chain reaction (qRT-PCR) and Western blot. Results:In vitro cell experiment: the secretion of IL-1β, TNF-α and IL-6 in the supernatant of primary macrophages in TREM-1 agonist group was higher than those in DMSO vehicle group, while the secretion of IL-1β, TNF-αand IL-6 in the supernatant of primary macrophages in TREM-1 agonist + QUE group were lower than that of TREM-1 agonist group (all P<0.001). The expression of TREM-1 protein in LPS group was higher than that in control group ( P<0.05), while the expression of TREM-1 protein in LPS + QUE group was lower than that in LPS group ( P<0.05). Animal experiments showed that compared with the control group, the ALI model group had higher lung pathological injury score, more total cells, macrophages and neutrophils in BALF and increased TNF-α, IL-6, IL-1β content (all P<0.001). The above indexes in QUE group were lower than those in ALI model group (all P<0.001). The results of qRT-PCR and Western blot showed that compared with the control group, the expression of TREM-1 mRNA and protein in the lung tissue of ALI model group was increased, while the expression of TREM-1 mRNA and protein in the lung tissue of QUE group was lower than that of ALI model group (all P<0.05). Conclusions:Quercetin can inhibit TREM-1 activation, reduce macrophage inflammatory response and LPS induced acute lung injury in mice.

Objective To observe the dynamic changes of cardiac lymphangiogenesis in Doxorubicin(DOX)-induced dilated cardiomyopathy(DCM)model mice,and to study the the protective mechanism of Kuoxin Decoction.Methods The DCM mouse model was established by intraperitoneal injection of DOX,and the dynamic observation was performed every week.On this basis,60 C57BL/6 mice were randomly divided into 6 groups(n=10):control group,Model group,L-KXD,M-KXD and H-KXD groups and Captopril group.After successful modeling,the KXD and the positive control drug Captopril were administered continuously for 28 days.Echocardiography was used to detect cardiac function in mice,HE staining and Masson staining were used to observe pathological and morphological changes of the heart,Whole-mount immunofluorescent staining was used to detect the expression of LYVE-1 and Podoplanin in epicardial lymphatic vessels,Western blot was used to detect the expression of VEGFR-3 protein,and qPCR was used to detect the expression of VEGFR-3 mRNA.Results DCM mice induced by DOX showed significant cardiac function decline from the third week(DOX:15 mg·kg-1,P<0.05),and significant ventricular remodeling at the fifth week(DOX:15 mg·kg-1,P<0.01);The lymphatic vessel area of the mouse heart decreased significantly from the fourth week(DOX:20 mg·kg-1,P<0.0001),and the expression of VEGFR-3 decreased significantly from the third week(DOX:15 mg·kg-1,P<0.01).Conclusion KXD can improve ventricular remodeling and cardiac function in DOX-induced DCM mice,promote cardiac lymphangiogenesis,and upregulate the expression of VEGFR-3 at protein and mRNA levels,with a better effect than captopril.DOX-induced cardiac lymphangiogenesis in DCM mice leads to severe myocardial fibrosis and weakened cardiac function,which gradually worsens with the accumulation of modeling time and dose.KXD can promote cardiac lymphangiogenesis and improve cardiac function in DOX-induced DCM mice.The mechanism may be related to the up-regulation of VEGFR-3 expression.

In recent years, China has issued many laws and regulations on enhancing hospital security order management, and the related system has been gradually improved. However, the management requirements of hospitals are hard to implement. In this way, hospitals have burdened intensive internal pressure to implement the policies, with the dilemma of insufficient external support. Based on the perspective of social co-governance, this study discussed the development of policies related to hospital security order management in China. Also, it summarized the best practices about how to ensure hospitals security order from the aspects of the government, hospitals as well as social organizations. Additionally, it analysed current existing problems, such as the lack of sufficient cooperation of the police-doctor linkage mechanism, the inadequate implementation of technical prevention measures, the delayed mediation and disposal of doctor-patient contradiction, the imperfect of supporting policies and etc.Finally, this paper provided relevant suggestions on long-term mechanism to ensure the security order of hospitals.
