Objective : To construct a visual literacy evaluation system for pupils by Delphi expert consultation method（Delphi method）. Methods : The visual literacy evaluation indices for pupils were preliminarily constructed through literature review. Twenty experts in relevant fields were invited and the visual literacy evaluation system for pupils was established by two rounds of expert consultation based on Delphi method. Results : The average age of 20 experts was（48.35±5.79）years old,of which 19 experts had senior titles,and 17 experts had master's degree or above. The enthusiasm of the experts in two rounds of consulting was both 100.00%. The average authoritative coefficient（W）of the experts was 0.88. For the first consulting round,the W of importance scores from experts was 0.91（P<0.01）;the W of operability scores from experts was 0.89（P<0.01）,which indicated satisfactory consistency. For the second consulting round,the W of importance scores from experts was 0.79（P<0.01）;the W of operability scores from experts was 0.77（P<0.01）,which also indicated satisfactory consistency. The finalized visual literacy evaluation system for pupils after two rounds of expert consultation included three primary indices（eye care knowledge literacy,eye care attitude literacy and eye care behavior literacy）,six secondary indices（basic knowledge,eye care behavior,eye care attitude,eye care willingness,bad eye care behavior and eye protection）and 40 tertiary indices（≥5.0 of eyesight among normal people,always wearing glasses due to poor eyesight and so on）. Conclusion The experts who participated in the construction of visual literacy evaluation system for pupils had strong professional representativeness,high enthusiasm,high authority and good coordination,and the evaluation system can be used for evaluating pupils visual literacy.

OBJECTIVETo explore an effective way to increase drought tolerance of Prunella vulgaris seed.

METHODThe treatment of drought stress to P. vulgaris seeds was made by the different concentrations of PEG solutions. Primed seeds germinated under 25% PEG.

RESULTAs concentrations of PEG increasing, seed germination percentage, germination index and vitality index reduced. Primed with 20%-25% PEG, 300-500 mg x L(-1) GA3 and 1.6%-2.0% KNO3-KH2PO4 could enhance three population seeds germination index and vitality index under drought stress. Treated with NaCl, seeds germination percentage and germination index of two population increased, which came from Nanjing Zijinshan and Anhui Jinzhai, respectively, while those of seeds from Gansu Chengxian reduced.

CONCLUSIONTreated with PEG, GA3, KNO3-KH2 PO4 under proper concentration, seed vigor, seed resistance under drought stress would increase.

Objective: To observe the effect of ticagrelor for non-ST-segment elevation acute coronary syndrome after percutaneous coronary intervention (PCI). Methods: A total of 200 patients with non-ST-segment elevation acute coronary syndrome after PCI were enrolled in this study.And the patients were randomly divided into the observation group (18 months treatment group, 100 cases) and control group (12 months treatment group, 100 cases) according to the digital table.The control group was given dual antiplatelet therapy (DAPT) for 12 months, and then, suspended the usage of ticagrelor.The observation group was treated by DAPT for 18 months.The major adverse cardiovascular events (MACCE) and the secondary end point events were observed. Results: The incidence rate of MACCE between the two groups had no statistically significant difference (χ²=0.298, P=0.862). And there was no statisticallysignificant difference in the incidence of the secondary end point events between the two groups (χ²=1.963, P=0.375). Conclusion The usage of DAPT beyond or equal 12 months doesn't reduce the incidence of MACC and it will not increase the blooding rate.The use of DAPT (aspirin and ticagrelor) should be used less than 12 months.

OBJECTIVETo assess the effect of Shenmai Injection (SMI) on left ventricular diastolic function (LVDF) in patients with chronic heart failure (CHF) by tissue Doppler imaging (TDI).

METHODSSixty-four CHF patients were randomly assigned to two groups, the observation group and the control group. Basic treatment including polarized liquid therapy was given to all the patients. In addition, SMI was given to patients of the observation group. The treatment duration was 14 days. TDI was performed in all the patients 3 days prior to the initiation of the treatment and one week after the medication to measure the average movement velocity of the mitral ring of the left ventricle at the early systolic stage and late diastolic stage (Ea and Aa); the outcomes were compared with the corresponding parameters obtained from blood flow Doppler echocardiography, namely, the velocity of the E-wave (E) and A-wave (A).

RESULTSAfter treatment, Ea and Ea/Aa increased and Aa decreased significantly in the observation group (P<0.05). In the control group, although some improvement was seen, there was no statistically significant change (P>0.05). No statistical significance was shown between groups in these parameters after treatment.

CONCLUSIONTDI assessment shows that SMI could effectively improve the LVDF in CHF patients.

Objective:To investigate the relationship between n7-methylguanosine (m7G) related long non-coding RNA (lncRNA) expression and glioma prognosis, and to construct a prognosis model with m7G-related lncRNA in patients with glioma.Methods:Data related to the test set and validation set were downloaded from the Cancer and Tumor Genome Atlas (TCGA) database and the China Glioma Genome Atlas (CGGA) database. LASSO regression and random forest algorithm were used to establish the glioma prognosis model with m7G related lncRNA. Individualized risk scores were calculated using the weighted expression levels of the 12 extracted lncRNA coefficients, and test set and validation set glioma patients were categorized into high and low risk groups based on median risk score. Kaplan-Meier survival curve was drawn, the comparison method used log rank test. The efficacy of risk score in predicting the 1-, 2- and 5-year survival rate in patients with glioma was evaluated using the receiver operating characteristics (ROC) curve.Results:A total of 12 lncRNA associated with m7G were obtained, with a risk score = 1.026 × AC002454.1 + 1.086 × AC131097.4 + 1.039 × AC147651.3 + 1.01 × AGAP2-AS1 + 1.036 × CRNDE + 0.733 × GDNF-AS1 + 1.321 × HOXD-AS2 + 0.934 × LINC00641 + 1.183 × PAXIP1-AS2 + 1.258 × PVT1 + 0.909 × SOX21-AS1 + 0.754 × TTC28-AS1, with a median risk score of - 0.45 scores. Kaplan-Meier survival curve analysis result showed that the median survival time in high risk group was significantly shorter than that in low risk group (1.98 years vs. 9.51 years, log-rank χ2 = 131.78, P<0.01). ROC curve analysis result showed that the area under the curve (AUC) of risk score in predicting the 1-, 2- and 5-year survival rate in patients with glioma was 0.891, 0.923 and 0.912. In the validation set of glioma patients, Kaplan-Meier survival curve analysis result showed that the median survival time in high risk group was significantly shorter than that in low risk group (1.29 years vs. 6.88 years, log-rank χ2 = 103.27, P<0.01); ROC curve analysis result showed that the AUC of risk score in predicting the 1-, 2- and 5-year survival rate in patients with glioma was 0.724, 0.795 and 0.762. In the test set and validation set, multivariate Cox regression analysis result showed that the risk score was the independent risk factors of prognosis in patients with glioma ( HR = 1.992 and 1.247, P<0.01 or <0.05). Conclusions:A risk score model with m7G related lncRNA based on transcriptome is a novel approach to predict the prognosis of glioma patients.
