Objective To explore the effect of age on the fracture healing through bioinformatical analysis of gene ex?pression data in GEO, and to screen critical molecular targets and pathways involved in this process. Methods Through R programming language, we identified different expressed genes between 26/52 week old rats and 6 week old rats in every time points of the experiment (No fracture;3 days, 1 week, 2 weeks, 4 weeks and 6 weeks after fracture). By comparison of these different expressed genes, those genes that may contribute to fracture healing were identified. Function annotation was conducted based on DAVID database and PPI network that was constructed via STRING database. Results Compared with 6 week old rat, 52 week old rat show more different genes at 2, 4 and 6 weeks after fracture as well as more than intact rats. At the time point of 6 weeks after fracture, 26 week old rat present 4 different genes while 52 week old rat present 99 differ?ent genes compared with 6 week old rat. We totally found 99 genes that might play important roles in the process of fracture healing. These genes involved in biological process related to bone healing, immune, inflammatory and etc. Also, two screened gene enriched KEGG pathways were identified: ECM-receptor interaction and Arachidonic acid metabolism. Through the analysis of PPI network, Pcna, Fn1, Casp3 and etc, who present high density connectivity in PPI network, were screened out. Conclusion Pcna, Casp3 and Fn1 and etc might play important roles in fracture healing through affecting ECM-receptor interaction and Arachidonic acid metabolism.

Objective:To investigate the relationship between Tei index and right heart function in patients with pneumoconiosis complicated with pulmonary heart disease (PHD).Methods:108 cases of pneumoconiosis patients with PHD in our hospital from January 2018 to January 2020 were randomly selected and divided into three groups according to the X-ray diagnostic criteria of pneumoconiosis, including 50 cases in stage Ⅰ group, 25 cases in stage Ⅱ group and 33 cases in stage Ⅲ group. All patients were examined by ultrasonic cardiography (UCG); the right ventricular Tei index and brain natriuretic peptide (BNP) levels, right ventricular outflow tract (ROVT) diameter, main pulmonary artery (MPA) diameter, right ventricular anterior wall thickness (RVAW), right ventricular diameter (RV), right atrial diameter (RA), pulmonary artery pressure (PASP), Tei index were compared in groups; Pearson correlation analysis was used to analyze the correlation between UCG index and BNP level; multiple linear regression analysis was used to analyze the influencing factors of BNP.Results:The levels of RV, Tei index and BNP in Ⅰ stage group were significantly lower than those in Ⅱ stage group, and the levels of RV, Tei index and BNP in Ⅱ stage group were significantly lower than those in Ⅲ stage group ( P<0.05). There was no difference in ROVT, MPA, RVAW, RA, PASP in the three groups ( P>0.05). Pearson correlation analysis showed that ROVT, RV, Tei index in UCG indicators and BNP level were positively correlated ( P<0.05); multiple linear regression analysis showed that RVAW and Tei indexes were the main influencing factors of BNP levels ( P<0.05). Conclusions:The right heart Tei index of patients with pneumoconiosis and PHD has a good correlation with BNP level, and is the main influencing factor of BNP level, which can make up for BNP deficiency and effectively evaluate the right heart function of patients.

Tigecycline is a new broad-spectrum antibiotic,which is the first glycyclines antibiotic used in clinic. Tigecycline is ac-tive against Gram-positive/negative bacteria and anaerobicbacteria, especially multidrug-resistant (MDR) pathogens. In this review, the literatures associated with tigecycline-induced coagulopathy published after 2005 were searched in Pubmed and the clinical charac-teristics as well as the research progress were summarized. The mechanism of tigecycline-induced coagulopathy was also explored. Cli-nicians should observe coagulation markers of patients during the treatment with tigecycline. If coagulation disorders or active bleeding occurs,tigecycline treatment should be stopped and symptomatic and supportive treatment should be given immediately.

OBJECTIVE:
To explore whether laryngopharyngeal simulator teaching can improve the quality of clinical operation compared with traditional preclinical teaching program.
METHOD:
Sixty-five surgical interns were randomly divided into two groups. Experimental group was given traditional clinical practice together with simulator for laryngopharyngeal training, while control group received traditional clinical practice only. The teaching effect were compared through the operation assessment.
RESULT:
After simulation training, the performance of experimental group was superior to that of the control group, and the difference was statistically significant (P < 0.05).
CONCLUSION
Simulator can improve the quality of teaching. It is recommended for teaching hospital and doctor's training base and deserves further promotion.
