555 medical vocational students were surveyed with questionnaire to data regarding their employment intentions. The study showed that the employment rate in basic-level medical organizations and the degree of job satisfaction of college students were low. The main factors were economic benefits, living environment, hospital equipment status, self-awareness. Therefore, in order to encourage medical vocational students to choose basic-level medical organizations, it is important to train health talents which is suitable for the grass-roots level, develop basic-level medical organization service qualities and pays more attention to the employment guidance in higher vocational schools, which can help medical vocational students cultivate proper views of employment.

Objective To investigate the effect of high uric acid(HUA) on insulin sensitivity (IS) in 3T3-L1 adipocytes and its mechanism. Methods 3T3-L1 adipocytes were pretreated with HUA with or without NAC,and then stimulated by insulin. The cell viability of 3T3-L1 adipocytes was detected by CCK-8 assay. The glucose consumption was measured by glucose oxidase method. The levels of phospho-IRS-1,phospho-Akt and GluT4 protein were tested by western blot. Results HUA could inhibit insulin-induced glucose consumption,phosphorylation of Akt (Thr308),dephosphorylation of IRS-1 (Ser307) and the GluT4 protein expression (P<0.05). All the above could be blocked by NAC(P<0.05). Conclusion HUA can inhibit inulin stimulated IRS-1/Akt signaling and GluT4 expression,and thus induced insulin resistance in 3T3-L1 adipocytes.

OBJECTIVETo observe the effect of rosiglitazone on the content of cholesterol and expressions of Acy-coenzyme A: cholesterol acyltransferase 1 (ACAT-1) and scavenger receptor class B type I (SR-BI) in RAW264.7 macrophage-derived foam cells and explore the anti-atherosclerotic mechanism of rosiglitazone.

METHODSRAW264.7 macrophages were incubated with oxidized low-density lipoproteins (ox-LDL) or with both ox-LDL and rosiglitazone (5, 10, or 20 µmol/L). Oil red O staining was used to observe the formation of foam cells, and cholesterol oxidase was used to determine the content of cellular cholesterol contents. Western blotting was used observe the expressions of ACAT-1 and SR-BI in RAW264.7 foam cells.

RESULTSCompared with the control cells, RAW264.7 macrophage-derived foam cells showed significantly increased contents of total cholesterol and free cholesterol (P<0.01) and ACAT-1 expressions (P<0.05) with mildly increased SR-BI expression (P>0.05). Rosiglitazone treatments significantly lowered the contents of total cholesterol and free cholesterol (P<0.05), decreased the expression of ACAT-1 (P<0.05), and increased SR-BI expression (P<0.05) in the foam cells in a dose-dependent manner.

CONCLUSIONRosiglitazone can decrease the contents of total and free cholesterol, down-regulate ACAT-1 expression and up-regulate SR-BI expression in the foam cells produce the anti-atherosclerotic effect.

Objective:To compare the effects of five different types of videolaryngoscopes in patients with a simulated difficult airway.Methods:575 patients who needed endotracheal intubation in Nanjing Hospital Affiliated to Nanjing Medical University from May 2021 to September 2021 were randomly divided into 5 groups [UE videolaryngoscope group (U group), GlideScope videolaryngoscope group (G group), C-MAC videolaryngoscope group (C group), Airtraq videolaryngoscope group (A group) and A. P.advance videolaryngoscope group (AP group)], with 115 patients in each group. They all wore cervical collar to simulate difficult airway. The main observation index was the success rate of first endotracheal intubation. Secondary observation indicators included overall success rate, laryngoscope exposure field, intubation time, operator′s subjective score, cause of failure, adverse events, and complications of intubation.Results:The patients′ mouth opening degree was reduced from (46±6)mm to (24±4)mm ( P<0.05) after wearing the cervical collar; The success rate of the first endotracheal intubation were 96%(UE), 92%(C-MAC), 86%(GlideScope), 85%(Airtraq), and 60%(AP.Advance) respectively, with statistically significant difference ( P<0.05); Compared with AP group and G group, the incidence of soft tissue injury or bleeding in U group and C group were lower ( P<0.05); There were significant difference in the overall success rate of videolaryngoscopes, laryngoscope visual field exposure, intubation time, the subjective score of the operator and adverse events ( P<0.05); There was no significant difference in the complications of intubation among the groups ( P>0.05). Conclusions:Among 575 patients with a simulated difficult airway with limited neck mobility and limited mouth opening, there were significant differences in the use of five videolaryngoscopes. Among them, UE video laryngoscope had the highest first intubation success rate and lowest tissue trauma rate, C-MAC video laryngoscope, GlideScope video laryngoscope and Airtraq video laryngoscope followed in performance, while A. P.Advance video laryngoscope performed the worst.

Objective: Previous research has explored a variety of mental disorders associated with Internet Gaming Disoder (IGD) and Social Media Addiction (SMA). To date, few studies focused on the network characteristics and investigated mood and sleep symptoms across SMA and IGD of adolescence at a group-specific level. This study aims to identify different characteristics of IGD and SMA and further determine the group-specific psychopathology process among adolescents. Methods: We conducted a cross-sectional study to recruit a cohort of 7,246 adolescents who were scored passing the cutoff point of Internet Gaming Disorder Scale-Short Form and Bergen Social Media Addiction Scale, as grouped in IGD and SMA, or otherwise into the control group. Patient Health Questionnaire-9, Generalized Anxiety Disorder 7-item, and Pittsburgh Sleep Quality Index were assessed for the current study, and all assessed items were investigated using network analysis. Results: Based on the analytical procedure, the participants were divided into three groups, the IGD group (n=789), SMA group (n=713) and control group (n=5,744). The edge weight bootstrapping analysis shows that different groups of networks reach certain accuracy, and the network structures of the three groups are statistically different (pcontrol-IGD=0.004, pcontrol-SMA<0.001, pIGD-SMA<0.001). The core symptom of SMA is “feeling down, depressed, or hopeless”, while IGD is “feeling tired or having little energy”. Conclusion Although IGD and SMA are both subtypes of internet addiction, the psychopathology processes of IGD and SMA are different. When dealing with IGD and SMA, different symptoms should be addressed.
