Objective To study the application of standardized A/B ultrasonography for the orbital vascular lesions. Methods Standardized A/B ultrasonography was performed on orbital vascular lesions of 145 cases. Results The orbital vascular lesions included the cavernous hemangiomas in 79 cases, venous hemangiomas 19 cases, lymphangiomas 15 cases, infantile hemangiomas 5 cases, varix 12 cases and carotid-cavernous sinus fistula 15 cases. The positive rate of standardized A/B scans was 98.6 %, false negative 1.4 %.Conclusions Standardized A/B ultrasonography can make accurate diagnosis for orbital vascular lesions. B-mode ultrasonography mainly shows the shape, location and the relation to normal orbital structure, but A-mode ultrasonography is more accurate in internal reflectivity of lesions, and sound attenuation and quantitative. Combined B-mode and A-mode ultrasonography is more effective for diagnosis of orbital vascular lesions.

Objective To investigate the clinical effect and analysis of Shah Glenn Dean combined with acarbose in the treatment of newly diagnosed elderly patients with type 2 diabetes mellitus.Methods 60 cases of newly diagnosed elderly patients treated in our hospital during the period from January 2015 to January 2017 in patients with type 2 diabetes mellitus is selected as the object of this study, they were randomly divided into control group and study group, 30 cases in each group.The control group was treated with acarbose treatment, the study group was treated with Shah Glenn Dean combined acarbose treatment, treatment time was 3months, glycosylated hemoglobin, after two groups of patients were in different treatment of hypoglycemia were observed and compared the rate of change, body mass index and blood glucose level changes.Results The patients in the control group, the incidence of hypoglycemia was 23.33%, patients in the study group, the incidence of hypoglycemia was 6.67%, patients in the study group,the incidence of hypoglycemia was significantly lower than that of control group, the difference was statistically significant between the groups(P <0.05); glycosylated hemoglobin levels in the study group were significantly lower than that of the control group of two patients, the difference was statistically significant between the groups(P <0.05); the total cost of the patients in the treatment group compared with the control group had no significant difference, the difference was not statistically significant.Conclusion Significant clinical therapeutic effect of saxagliptin combined with acarbose in the treatment of newly diagnosed elderly patients with type 2 diabetes, can make the patient's blood glucose levels were significantly lower,with high security, the incidence of hypoglycemia was significantly reduced, but also can reduce the weight of patients, the total cost in the course of treatment did not increase that will not cause economic burden on patients, it is worthy of clinical application.

Objective To explore the related factors of senile acute pulmonary thromboembolism(PTE) patients,and to observe the prognosis and analyze the strategy of control and prevention to reduce the incidence. Methods 50 elderly patients with acute PTE were selected,related factors were analyzed by using the retrospective investigation,and the prevention and control were administrated.Results The mainly disease occurred of the elderly patients with acute PTE were combined with chronic diseases 42% (21 /50),with lower extremity DVT 26.00%(13 /50)and with recent trauma,fracture and operation 20%(10 /50).Elderly patients with acute PTE who were ≥70 years of age and lying in bed the time≥1 month,were 58%(29 /50)and 62%(31 /50),which were higher than those of the other age <70 years old and lying in bed time <1 month of patients,the difference was statistically signifi-cant(χ2 =9.26,9.80,all P <0.05).Conclusion The related risk factors for elderly patients with acute PTE mainly correlate with age,lying in bed time,chronic diseases,patients with lower extremity DVT and recent trauma,fracture, operation,the variety of factors and overlap each other.Mastering the variety factors of PTE in the nursing process,and taking effective measures to prevent and control the factorscan reduce or avoid the occurrence of acute PTE,and im-prove the prognosis of the patients.

Objective To evaluate disinfectant efficacy of air disinfector and ultraviolet lamp.Methods Domestic literatures were searched by computer,RevMan 5 .3 software provided by the Cochrane collaboration was used for quantitative analysis,efficacy of two kinds of air disinfection methods was compared. Results A total of 1 1 articles met the inclusion criteria. Because the heterogeneity of literatures,random effects model analysis was adopted, colony forming unit (CFU)before disinfection(WMD= -26.28,95% CI:[-60.31,7.75],P>0.05 )and immediately-after disinfection(WMD= 22.45,95% CI:[-34.24,79.13],P>0.05)had no obvious difference between two methods respectively,but CFU of air disinfector 2 hours after disinfection was significantly less than ultraviolet lamp group(WMD= -345.11,95% CI:[-478.28,-211.94],P<0.05).Conclusion Air disinfector has good continuous disinfection efficacy.

Objective To investigate effect of paclitaxel on expression of programmed death ligand-1 ( PD-L1 ) in the surface of cervical cancer TC-1 cells and its mechanism. Methods ①The cells were divided into two groups: paclitaxel group, paclitaxel combined with PKD blocker (G? 6976) group. There were 4 concentration gradient and 5 holes for each group, and each hole has its corresponding concentration of drugs. Influence of paclitaxel on TC-1 cell viability and effect of PKD blocker G? 6976 on IC50 value of paclitaxel were evaluated by MTT method.②The cells were divided into 0. 9% sodium chloride solution ( NS) group and paclitaxel group, There were 5 holes of each group. Effect of paclitaxel on PD-L1 expression on the surface of TC-1 cells were measured by immunohistochemistry.③The cells were divided into 4 groups:NS+DMSO group, G? 6976 group, paclitaxel group and paclitaxel+G? 6976 group. There were 5 holes for each group. Effect of paclitaxel and G? 6976 on PD-L1 expression on the surface of TC-1 cells were measured by immunohistochemistry. The expressions of PD-L1 on the surface of cells were measured by immunofluorescence treated with different drugs. Results The IC50 value of paclitaxel was 40 μg·mL-1 in paclitaxel group, and 38. 9 μg·mL-1 in paclitaxel combined with PKD blocker G? 6976 group, without significant difference between the two groups (P>0. 05). The expression of PD-L1 in the surface of TC-1 cells were significantly higher in paclitaxel group than in negative control group [(88. 48±13. 44)% vs. (39. 59±5. 99)%, P<0. 05]. The expression of PD-L1 in the surface of TC-1 cells was (79. 7%±4. 7)% after treatment with paclitaxel combined with PKD blocker G? 6976 for 24 h, and it was significantly lower than that in paclitaxel group [(96. 8±2. 5)%, P<0. 05]. Conclusion Paclitaxel promotes the expression of PD-L1 in the surface of TC-1 cells, which could be significantly inhibited by blocking PKD pathway. Paclitaxel may exert its effect through PKD pathway.
