Meta-Analysis on Safety of Dapagliflozin in Patients with Type 2 Diabetes Mellitus  [PDF]
Lili She, Hongyan Wu
Yangtze Medicine (YM) , 2018, DOI: 10.4236/ym.2018.23014
Abstract: Objective: To evaluate the safety of dapagliflozin for Type 2 Diabetes Mellitus (T2DM). Methods: A systematic search of Pubmed, Embase, Cochrance Library, Web of Science, CNKI, Wanfang Data and VIP database for randomized controlled trials (RCTs) comparing dapagliflozin with placebo was performed up to February 2018. The index words included dapagliflozin, type 2 diabetes mellitus and randomized controlled trial. Results: A total of 19 RCTs involving 7704 participants were incorporated into the study. Compared with placebo, dapagliflozin did not increase the risk of hypoglycemia [OR = 1.14, 95%CI (0.95, 1.36), P = 0.17] and hypotension [OR = 1.43, 95%CI (0.94, 2.17), P = 0.10], but significantly increased the incidences of renal adverse events [OR = 1.57, 95%CI (1.17, 2.09), P = 0.002], genital tract infection [OR = 3.65, 95%CI (2.93, 4.56), P < 0.00001] and urinary tract infection [OR = 1.36, 95%CI (1.15, 1.61), P = 0.0004] and related doses. Conclusions: Generally, dapagliflozin had no risk of hypoglycemia and hypotension in patients with T2DM, but there were risks of renal adverse events and urogenital tract infection. Due to the limitations of this study, larger samples and RCTs with long-term follow-up are needed for further verification.
Role of Time-Domain Based Access Control Model  [PDF]
Chaoqun Liu, Zhen Peng, Lili Wu
Journal of Software Engineering and Applications (JSEA) , 2016, DOI: 10.4236/jsea.2016.92004
Abstract: While Role-Based Access Control Model (RBAC) is being analyzed, the concept of Role of Time-domain Based Access Control Model (T-RBAC) is put forward. With time-domain added, both time-domain and authority control roles. The basic idea of T-RBAC is introduced and described formally, and the safely of this model is analyzed. The research shows that T-RBAC fulfills both rules of information security, which are principle of least privilege and separation of duties. With practical application of T-RBCA, it can handle most of the time-related or authority-related problems. What’s more, it also increases the security level, flexibility and dynamic adaptation of the system and has lower complexity than system only handled by authority. This model also can solve conflicts caused by authority.
A Study of Feature Stability of Contact-Less Imaging Based on Palm Vein  [PDF]
Weiqi Yuan, Wei Wu, Lantao Jing, Deqi Kong, Lili Wang
Engineering (ENG) , 2013, DOI: 10.4236/eng.2013.510B110

Palm vein hidden under the skin and its distribution feature is hard to be stolen, which makes the palm vein recognition to be a high security biometric authentication method. Contact-less palm vein imaging can avoid the spread of disease, thus expanding the application range of palm vein biometric authentication devices. However, due to the different un-derstanding of the right imaging position and the change of fingers open degree, contact-less palm vein image acquisi-tion led to a certain degree of translation, rotation, scaling and shear, that is, the image deformation. Image deformation causes the imaging feature unstable. In this paper, the effect of image deformation to the stability of palm vein features is studied by some similarity parameters. First, feature points in the palm were marked, contact-less imaging and con-tact imaging of palm vein were acquired. Then, this paper calculated the similarity parameters of the contact-less imag-ing to contact imaging and gave corresponding analysis. Experimental results show that contact-less palm vein imagingwas stable, and derived the linear regression equation of relationship between sample space and the recognition rate: y =?0.000903x + 1.0332, coefficient of determination R2 = 0.9824. This research provided effective and detailed data to the study of contact-less palm vein recognition and gave powerful support to contact-less multi-feature fusion recogni-tion based on hand.

Effective connectivity of dorsal and ventral visual pathways in chunk decomposition
QiYuan Wu,LiLi Wu,Jing Luo
Science China Life Sciences , 2010, DOI: 10.1007/s11427-010-4088-z
Abstract: Chunk decomposition is defined as a cognitive process which breaks up familiar items into several parts to reorganize them in an alternative approach. The present study investigated the effective connectivity of visual streams in chunk decomposition through dynamic causal modeling (DCM). The results revealed that chunk familiarity and perceptual tightness made a combined contribution to highlight not only the “what” and the “where” streams, but also the effective connectivity from the left inferior temporal gyrus to the left superior parietal lobule.
Primary Cutaneous MZL with Amyloid Deposition, Initially Misdiagnosed as Amyloidosis Mimics Primary Dural MZL upon Dural Dissemination  [PDF]
Miaoxia He, Lili Wu, Minghua Zhu, Chenguang Bai, Shimin Zhang, Jianjun Wang
Open Journal of Pathology (OJPathology) , 2013, DOI: 10.4236/ojpathology.2013.31004

Primary cutaneous marginal zone B-cell lymphoma (MZL) is considered a cutaneous counterpart of extranodal MZL of mucosa-associated lymphoid tissue and an indolent lymphoma. Amyloid deposition in this tumor is very rare. We report here a case of primary cutaneous MZL with massive amyloid deposition. The tumor disseminated to the dura and mimicked primary dural MZL. The patient had a four year history of the recurrence cutaneous lesions with a misdiagnosis of amyloidosis. The correct diagnosis was made after the metastatic dural lesion was confirmed by radiology, pathology and molecular biology approaches. It is of crucial importance for differential diagnosis to avoid misdiagnosis and the patients are indeed required long-term regular examinations and treatment because of the possibility of recurrence or dissemination.

In Vitro Cytotoxicity Evaluation of Highly Absorbent Foam Dressings Based on Silver Zirconium Phosphate via IC50 Value  [PDF]
Chenghu Liu, Li Hou, Lili Liu, Zhonghua Qu, Xin Wang, Xiaoxia Sun, Ping Wu, Yanping Shi
Journal of Biomaterials and Nanobiotechnology (JBNB) , 2016, DOI: 10.4236/jbnb.2016.71005

In this study, we, for the first time, tried to apply IC50 values (inhibitory concentration estimated to affect the endpoint in question by 50%) in the MTT colorimetric assay to investigate the cytotoxic effects of highly absorbent foam dressings based on silver zirconium phosphate, a newly nano-based matrix. Our results showed that silver released from dressings based on silver zirconium phosphate attributed mainly to highly cytotoxic to L929 cells cultured with MEM containing 10% fetal bovine serum. In addition, we have also compared the IC50 values among different dilutions of AgNO3 solution, silver based dressing extracts and material reference control (ZDEC) extracts using the optimized MTT assay, along with characterizing the silver content in the dressing extracts using atomic absorption spectroscopy. Results have shown that the IC50 values of AgNO50 solution, silver based dressing extracts and ZDEC extracts are 3.5 μg/mL, 3.8 μg/mL and 8.4%, respectively. And there exist some good agreements between qualitative and quantitative evaluation method as well. In conclusion, our study has led to the view that the IC50 value is a promising quantitative index for screening cytotoxicity with regard to silver based dressings.

Coping Strategies as a Mediator of Posttraumatic Growth among Adult Survivors of the Wenchuan Earthquake
Lili He, Jiuping Xu, Zhibin Wu
PLOS ONE , 2013, DOI: 10.1371/journal.pone.0084164
Abstract: Objective By testing the mediating effect of coping strategies on the relationship between social support (SS) and posttraumatic growth (PTG), the aim of this research was to develop a new approach for the study of post-disaster psychological intervention. Methods A mediating effect model analysis was conducted on 2080 adult survivors selected from 19 of the counties hardest-hit by the 2008 Wenchuan earthquake. The Social Support Rating Scale and the Coping Scale were used to predict the PTG. Results A bivariate correlation analysis showed that there was a correlation between posttraumatic growth, social support and coping strategies. The mediation analysis revealed that coping strategies played a mediating role between social support and posttraumatic growth in survivors after the earthquake. Conclusion The results demonstrated that mental health programs for survivors need to focus on the establishment of a good social support network, which was found to be conductive to maintaining and increasing mental health levels. At the same time, adequate social support is able to assist survivors in adopting mature coping strategies, such as problem solving and asking for help. Hence, social support was found to play a vital role in balancing and protecting mental health.
