ABSTRACT
@#AIM: To study the myopia and influencing factors among primary school students in Haidian, Beijing. <p>METHODS: A total of 801 primary school pupils from grade one to grade three of Beijing were selected according to the cluster stratified sampling method, and 801 questionnaires were collected from the scene, which accorded with 757 people aged 7-10 years old, and 757 valid questionnaires, the prevalence rate of this study was 24.4%. The baseline data of all the subjects were collected through questionnaires. The data of myopia were compared. The Logistic regression equation was used to calculate the factors causing myopia. <p>RESULTS: The main factors leading to myopia in primary school were reading time, electronic product use time, parents' myopia, outdoor activity time, and reading and writing postures. The above difference data was brought into the Logistic regression equation to confirm. <p>CONCLUSION: The myopia rate of primary school students in Beijing has reached a high level. There are many problems in family, daily life and students themselves. It is necessary to prevent and control the occurrence of myopia and promote the vision health of primary school students.
ABSTRACT
Objective:To explore high-quality of emergency clinical pathway of percutaneous coronary intervention (PCI)in patients with acute ST elevation myocardial infarction (STEAMI),and systematically evaluate its clinical effect.Methods:A total of 627 STEAMI patients,who received successful emergency PCI from Mar 2008 to Sep 2016,were selected.According to hospitalization sequence,they were divided into traditional pathway group (n=298)and high-quality pathway group (n=329,received new clinical pathway strategy formulated by present study). Reperfusion time and level of infarct related artery (IRA),postoperative mortality,the 36-item short-form heath survey (SF-36)score at discharge,NYHA class and left ventricular ejection fraction (LVEF)on one month after PCI were counted and analyzed in two groups.Results:Compared with traditional pathway group,there were signif-icant reductions in door-to-balloon time [(86.3 ± 22.4)min vs.(65.9 ± 17.8)min]and onset-to-balloon time [(189.5±30.2)min vs.(154.6±27.2)min],and significant rise in percentage of TIMI ≥grade I of IRA before PCI (5.0% vs.25.5%)in high-quality pathway group (P <0.01 all),but there was no significant difference in per-centage of TIMI grade III of IRA after PCI between two groups,P =0.393. Compared with traditional pathway group,there were significant rise in total SF-36 score [(66.1±11.2)scores vs.(75.9±12.8)scores]at discharge and LVEF [(49.3±11.2)% vs.(54.1 ±13.6)%]on one month after PCI,and significant reduction in NYHA class [(1.97±0.65)classes vs.(1.68±0.51)classes]on one month after PCI in high-quality pathway group (P <0.05 or <0.01 ).There was no significant difference in postoperative mortality between two groups,P =0.803. Conclusion:High-quality emergency clinical pathway of PCI in STEAMI patients contributes to early reperfusion of IRA,shortens door-to-balloon time,significantly improves their clinical prognosis,which is worth extending.

ABSTRACT
To observe the effect of methylprednisolone [MP] plus adrenaline to treat patients injured by wasp stings. This study was carried out at The First College of Clinical Medical Science, China Three Gorges University, Yichang, Hubei Province, China, from June to November 2008. A total of 45 cases were divided into 2 groups. The MP was used alone in the control group, and MP plus adrenaline was used in the observation group. We compared the clinical effect between the 2 groups. The alanine aminotransferase [ALT] [64.05 +/- 59.31 versus 124.14 +/- 80.01 U/L], and creatine kinase isoenzyme [CKMB] [90.32 +/- 85.19 versus 216.68 +/- 277.58 umol/L] levels of the observation group were significantly lower than those of the control group. The length of hospital stay of the observation group was significantly shorter than that of the control group [7.23 +/- 2.93 versus 11.23 +/- 8.02], while complications from the wasp sting were fewer than those of the control group. In addition, the level of peripheral blood leukocytes was positively correlated with the number of stings [r=0.733, p=0.001], levels of ALT and CKMB [r=0.627, p=0.001, and r=0.705, p=0.001], and length of hospital stay [r=0.667, p=0.001]. Allergic and inflammatory responses play an important role in addition to the direct effect of wasp venom on the human body. Compared with MP alone, early combination of adrenaline helps to further inhibit the diffusion of allergy and inflammatory cytokines, and therefore reduce the severity of injury
