Objective To investigate the relationship between personality and social network profile-based information.Methods 438 college students were recruited,and Big five inventory NEO-FFI was applied to all subjects.The participants' Renren web profile information were recorded.Results ①Individuals with higher score of Extraversion had more friends (2.47 ± 0.29,2.34 ± 0.27,F =17.861,P =0.000),shared more (2.51 ± 0.56,2.32 ± 0.57,F =8.617,P =0.004),pasted more photographs (2.30 ± 0.51,2.14 ± 0.56,F =5.523,P =0.02).② There was a U shape correlation (t =2.258,P =0.024,t =2.115,P =0.035) between levels of neuroticism and numbers of blogs (0.66 ± 0.71) and photographs (1.92 ± 0.83).③There was no difference on numbers of friends (2.38 ± 0.31,2.39 ± 0.27,F =0.149,P =0.700) and e-gifts received (1.30 ± 0.52,1.26 ± 0.45,F =0.257,P=0.613) between participants of high and low levels of agreeableness.④ Individuals with higher scores in openness shared more with others(2.46 ± 0.57,2.29 ± 0.58,F =5.248,P =0.023).⑤ Individuals being more conscientious had more blogs(1.08 ±0.49,0.96 ±0.48,F=3.064,P=0.082).Conclusion There are significant differences about profile-based information among college students with different personality.

Objective To investigate the relationship between social network behaviors and personality.Methods Both questionnaires including self-reported Renren questionnaire and the simplified Chinese version of NEO five-factor inventory (NEO-FFI) were completed in university students (n =509).Results (1) Individuals with higher score of Extraversion used Renren applications more frequently,such as using Wall (2.26 ± 0.51,2.10±0.40,t=3.163,P=0.002),Status Update (2.58 ±0.71,2.33 ±0.62,t =3.268,P=0.001),Image (2.05±0.88,1.81 ±0.72,t=2.628,P=0.009),and Photo (2.17 ±0.49,1.96 ±0.33,t=4.409,P＜0.01).(2)Individuals with higher score of Openness of Experience were more likely to use Gift (2.01 ± 0.49,1.83 ± 0.59,t =2.870,P =0.005).(3) Individuals who were willing to use Blacklist (41.93 ± 4.41,43.07 ± 4.72,t =2.207,P =0.028) and who were willing to send private messages (42.23 ± 4.79,43.27 ± 4.55,t =2.476,P =0.014) have higher score of Agreeableness.(4) Individuals who checked messages more often had higher score of Conscientiousness (41.59 ± 6.33,40.72 ± 5.67,37.56 ± 8.33,F =7.170,P =0.001).(5) Individuals with higher score of Neuroticism were more likely to be dependent to Renren (2.91 ± 1.01,2.48 ± 1.02,t =3.815,P ＜0.01).Individuals who were more likely to express their emotions on SNS had higher score of Neuroticism (33.10 ± 6.78,32.19 ± 6.16,31.36 ± 5.77,F=3.594,P =0.010).Conclusion The data suggest that the usage of social networking sites are related to personality factors.Personality can be used to predict university students' social networking behaviors.

Stroke is the first cause of death in China. Intravenous thrombolysis and early endovascular treatment can significantly improve the outcome of patients with ischemic stroke. With the continuous deepening of research, the time window of endovascular interventional therapy has been extended from 6 h to 24 h. Tissue stratification plays a vital role in the expansion of time window. This article reviews the implications of tissue stratification, imaging assessment methods, and their significance in endovascular treatment.

Objective:To evaluate the characteristics of carotid plaque and the immediate outcomes after carotid artery stenting (CAS) in diabetic and non-diabetic patients by optical coherence tomography (OCT).Methods:Patients underwent CAS and OCT before and after operation in the Department of Neurology, Jinling Hospital from January 2014 to March 2019 were enrolled retrospectively. The clinical features, the characteristics of carotid plaque on OCT and the immediate outcomes after CAS were compared between diabetic group and non-diabetic group. The risk factors of stent malapposition were analyzed.Results:A total of 46 patients were enrolled. Their age was 64.02±8.32 years and 41 were males (89.1%). There were 20 patients (43.5%) in the diabetes group and 26 (56.5%) in the non-diabetes group. The proportions of atherosclerotic plaque with thin fibrous cap (40.0% vs. 7.7%; χ2=5.166, P=0.023), plaque rupture (55.0% vs. 23.1%; χ2=4.945, P=0.026) and macrophage infiltration (60.0% vs. 30.8%; χ2=3.930, P=0.047) in the diabetic group were significantly higher than those in the non-diabetic group. Multivariate logistic regression analysis showed that older age (odds ratio [ OR] 1.208, 95% confidence interval [ CI] 1.033-1.413; P=0.018), coronary heart disease ( OR 15.953, 95% CI 1.142-222.952; P=0.040), alcohol consumption ( OR 6.192, 95% CI 1.098-34.923; P=0.039) and lower systolic blood pressure ( OR 0.944, 95% CI 0.894-0.997; P=0.037) were independently associated with stent malaposition. Conclusion:Compared with the non-diabetic patients, carotid plaque in diabetic patients may be more unstable. Older age, coronary heart disease, alcohol consumption and lower systolic blood pressure were associated with stent malaposition after carotid stenting. OCT can reveal the characteristics of carotid plaque and the immediate outcomes after CAS, which can provide strong evidence for treatment decision.

Objective: To investigate the inactivating effect of soap solution on rabies virus and to explore the concentration of soap solutions which could be effective in post-exposure prophylaxis (PEP) of rabies virus infection. Methods: The BSR and N2a cells were respectively infected by the mixture of different concentrations of soap solution and rabies virus CVS-11. Based on the direct immunofluorescent method (DFA) and reverse transcription PCR (RT-PCR), the inactivating effects of soap solutions on rabies viruse in BSR and N2a cells were detected, respectively. Results: This experiment established the BSR or N2a cells model in 24 well cell culture plates, and we found that the upper limit of soap solution concentration which BSR or N2a cells could tolerate was 1%. The inhibitory effect test of different soap solution on rabies virus showed that the 0.5% concentration of soap solution could completely inhibit the survival of CVS-11 strain in both the BSR and N2a cells, but the 0.1% concentration of soap solution could not inhibit the rabies viruses completely. Conclusions The 0.5%-1% concentration of soap solutions could inhibit the survival of CVS-11 strain in three minutes in vivo experiment.

Neovascular age-related macular degeneration(nARMD)is a prevalent age-related retinal disease that significantly impairs vision. Numerous studies have shown that lipid metabolism disorders contribute to the progression of nARMD. The relationship is complex and involved factors such as fatty acids, cholesterol, variations in lipid metabolism genes, and other influencing factors. Lipid metabolism disorders lead to retinal vascular abnormalities and inflammatory responses by triggering oxidative stress and inhibiting autophagy. This, in turn, accelerates the formation of new blood vessels and causes damage to macular cells and tissues. In animal experiments, drugs designed for lipid metabolism disorders have shown that regulating lipid metabolism could be a potentially effective strategy for treating nARMD. This article reviews the role of lipid metabolism in the progression and treatment of neovascular age-related macular degeneration, aiming to offer new insights for nARMD treatment.

Objective : To explore the effects of Er: YAG laser irrigation technology on smear layer removal and dentin microhardness. Methods : A total of 102 ex vivo premolars were selected to amputate the crown , leaving a root length of 13 mm , after mechanical preparation , there were divided into experimental group (3% sodium hypochlorite , 3% NaOCl) and control group (0. 9% sodium chloride solution , NS) , and received syringe , ultrasound and Er: YAG laser terminal irrigation , which were specifically grouped into NaOCl + syringe , NaOCl + ultrasound , NaOCl + laser, NS + syringe , NS + ultrasound and NS + laser groups ( n = 17 ) . Scanning electron microscopy (SEM) evaluated smear layer removal from the upper, middle and apical parts of the root. The Vickers microhardness tester measured the microhardness before and after irrigation. Results : The NaOCl + laser group had the best effect on removing the root canal smear layer, and the amplitude of reducing the microhardness of dentin was the largest. There was no significant difference in the reduction of microhardness compared with the NaOCl + ultrasonic group (P > 0. 05) . Conclusion Er: YAG laser⁃activated NaOCl solution improves the clearance of the smear layer and reduced the microhardness of dentin.
