Anti N-Methyl-D-Aspartate (NMDA) Receptor Encephalitis with Frustrated Diagnosis Course: A Case Report  [PDF]
Huanquan Liao, Hongyan Zhou, Ling Chen
World Journal of Neuroscience (WJNS) , 2015, DOI: 10.4236/wjns.2015.55032
Abstract: Anti-N-methyl-D-aspartate (NMDA) receptor encephalitis is a rare disease with uncertain etiology and pathogenesis that affects young women. Its diagnosis can be delayed because of the nonspecific neuropsychiatric symptoms in the foreground. This article describes the details of a recent complicated case of a patient with this condition which is related to an ovarian teratoma. Correct diagnostic and prompt treatment of anti-NMDA receptor encephalitis remains a serious clinical challenge due to its unspecific manifestations and varying response to treatments. The information will be of interest to clinicians working with encephalitis patients.

Huanquan Liao, Hua Hong, Hongxuan Wang
Open Access Library Journal (OALib Journal) , 2015, DOI: 10.4236/oalib.1102014
Abstract: Carotid artery atherosclerosis (CAA) is one of the major high-risk mechanisms of stroke. Relationship between IMT, carotid plaque echogenicity and carotid stenosis assessed by ultrasound has not been systemically studied, especially in subjects with mild to moderate carotid stenosis. In this study we measured these 3 different ultrasound-derived quantitative traits concurrently in the community population of southern China and compared their associations. We found that IMTmean in the non-stenosis group (0%), <30% group and ≥30% group were 0.72 ± 0.11 mm, 0.85 ± 0.13 mm, 0.90 ± 0.17 mm respectively. IMTmean of the <30% group and ≥30% group were higher than that of 0% group (P < 0.01), ≥30% group was higher than <30% group (P < 0.01). IMTmean in the no-plaque group, hyperechoic group and hypoechoic group were 0.75 ± 0.13 mm, 0.87 ± 0.17 mm, 0.84 ± 0.15 mm respectively. IMTmean of the hyperechoic group and the hypoechoic group was higher than that of the no-plaque group (P < 0.01), IMTmean of the hypoechoic group was lower than that of the hyperechoic group, though with no statistic significance (P = 0.58). The proportion of hyperechoic or hypoechoic plaque in the <30% group was higher than that in the non-stenosis group (P < 0.01), as well as proportion of hypoechoic plaque in the ≥30% group was higher than that in the <30% group (P < 0.01). Our study indicated that there is definite correlation between stenosis severity, plaque echogenicity characteristics and IMT in evaluation the extent of CAA with ultrasound. The result suggests that the 3 different ultrasound-derived quantitative traits, are a progressing process, and this process increases the risk of stroke, thus medical treatment especially stabilizing the plaques is necessary.
Severe Generalized Spinal Cord Atrophy and Marfan Syndrome: A Case Report  [PDF]
Huanquan Liao, Hongyan Zhou, Ling Chen
Open Access Library Journal (OALib Journal) , 2015, DOI: 10.4236/oalib.1102165
Abstract: Generalized spinal cord atrophy is rare. Several causes can be found responsible for this entity. Marfan syndrome (MS) is a clinically and allelically heterogeneous, heritable connective tissue disorder. Previous study has implicated neuromuscular involvement in this syndrome. Here, we report the description of a patient with generalized spinal cord atrophy, which may be attributed to MS. Though not all patients represent with spinal cord atrophy, our case suggests that generalized spinal cord atrophy may occur in a subgroup of MS patients. Our finding underscores the need to inform medical practitioners that neurologic involvement, especially generalized spinal cord atrophy, can occur in patients with MS. Further studies are warranted in order to better clarify this causal relationship association between MS and spinal cord atrophy.
Hepatic Myelopathy with Painful Tonic Spasm: A Case Report  [PDF]
Huanquan Liao, Zhichao Yan, Guidian Li, Hua Hong
Open Access Library Journal (OALib Journal) , 2015, DOI: 10.4236/oalib.1102078
Abstract: Hepatic myelopathy (HM) is a rare neurological complication of chronic liver disease, causing progressive spastic paraplegia or quadriplegia in the extremities with minimal sensory or sphincter impairment. In this article, the authors present one additional case with HM, with an exceptional clinical picture of painful tonic spasms within both thighs as the main complaint. A reduction in pain coinciding with a reduction in spasticity from treatments such as baclofen suggests a causal relationship between the two. We stress the importance of early recognizing this symptom before the spinal cord damage becomes irreversible.
Serum Neopterin as a Novel Marker for Carotid Artery Stenosis in Community Subjects  [PDF]
Huanquan Liao, Zhichao Yan, Hongxuan Wang, Hua Hong
Open Access Library Journal (OALib Journal) , 2018, DOI: 10.4236/oalib.1105083
Background: Carotid artery stenosis (CAS) is one of the major high-risk mechanisms of stroke. Neopterin, an immune modulator secreted by macro-phages, has been reported to be elevated in patients with cerebrovascular dis-ease. However, an association between serum neopterin level and CAS has not been firmly established. Objective: To investigate the cross-sectional relation-ship between serum neopterin levels and CAS assessed by ultrasound. Meth-ods: The study participants were volunteers in a community-based cohort aim-ing to prevent stroke in Guangzhou. Bilateral carotid artery ultrasonography was performed to assess the carotid atherosclerosis. After participant criterion screening and random sampling, finally 140 subjects were studied in our pre-sent study. Enzyme-linked immunosorbent assay was performed to measured serum neopterin concentrations. Results: Neopterin level in the CAS and con-trol group was 5.4 (3.3 - 7.3) nmol/L and 4.6 (3.6 - 5.4) nmol/L respectively, with a significant difference (P < 0.05). After multivariate adjusted, neopterin levels remained an independent factor. With per 1.0 nmol/L (approximately 1 IQR) increasing, the OR value was 1.84 (95% CI: 1.25 - 2.71, P < 0.05). ROC curve of serum neopterin concentrations for the prediction of CAS revealed that the area under curve was 0.665 (P < 0.01). The cutoff value of 5.1 nmol/L had a sensitivity of 68.6% and specificity of 61.5% in detecting CAS. Conclusion: These findings demonstrate that circulating neopterin level is increased in subclinical carotid atherosclerosis population with CAS and reinforce the key roles of inflammatory response in the pathogenesis.

Weihua Liao
Journal of Geographic Information System (JGIS) , 2012, DOI: 10.4236/jgis.2012.41006
Abstract: There are two methods for GIS similarity measurement problem, one is cross-coefficient for GIS attribute similarity measurement, and the other is spatial autocorrelation that is based on spatial location. These methods can not calculate subzone similarity problem based on universal background. The rough measurement based on membership function solved this problem well. In this paper, we used rough sets to measure the similarity of GIS subzone discrete data, and used neighborhood rough sets to calculate continuous data’s upper and lower approximation. We used neighborhood particle to calculate membership function of continuous attribute, then to solve continuous attribute’s subzone similarity measurement problem.

Chinese Medicine (CM) , 2012, DOI: 10.4236/cm.2012.31008
Abstract: This paper discussed the pathogenesis and the principle of treatment of the dry cough with yellow greasy coating. Combined the clinic observation with the TCM theory, we found that the main reasons about this dry cough are dryness in lung and stagnated phlegm. And heavy dosages herbs which can nourish Yin and clear away the heat should be adopted.
Intention to Create Legal Relations and the Reform of Contract Law: A Conservative Approach in the Modern Global Era  [PDF]
Zhixiong Liao
Beijing Law Review (BLR) , 2013, DOI: 10.4236/blr.2013.42011
Abstract: This paper is partially to refute the submissions by Gulati’s article recently published on Beijing Law Review which proposes abandoning the requirement of proving intention to create legal relations for the formation of an enforceable contract. After a critical analysis of the abandonists’ arguments, this paper argues that intention to create legal relations is the “marrow of contractual relationships” and the arguments for abandoning such a requirement because of the existence of consideration and/or offer and acceptance as test(s) of contractual enforceability is untenable and unconvincing. Consideration and/or offer and acceptance may be evidence of serious intention to be bound somehow but unnecessary intention to be bound legally. For a number of reasons, the doctrine of consideration is very unlikely to work any better than the intention to create legal relations test. If a test of contractual enforceability must be abandoned, that should be the doctrine of consideration rather than the intention to create legal relations. This paper compares the current positions of some common law jurisdictions, upholds the needs of stability, consistency, and the harmonisation of contract law in the modern global era, and proposes a conservative approach of contract law reform regarding the intention requirement and the related presumptions, that is, all common law jurisdictions should “go back” to the orthodox English position.
Data Fusion with Optimized Block Kernels in LS-SVM for Protein Classification  [PDF]
Li Liao
Engineering (ENG) , 2013, DOI: 10.4236/eng.2013.510B048

In this work, we developed a method to efficiently optimize the kernel function for combined data of various different sources with their corresponding kernels being already available. The vectorization of the combined data is achieved by a weighted concatenation of the existing data vectors. This induces a kernel matrix composed of the existing kernels as blocks along the main diagonal, weighted according to the corresponding the subspaces span by the data. The induced block kernel matrix is optimized in the platform of least-squares support vector machines simultaneously as the LS-SVM is being trained, by solving an extended set of linear equations, other than a quadratically constrained quadratic programming as in a previous method. The method is tested on a benchmark dataset, and the performance is significantly improved from the highest ROC score 0.84 using individual data source to ROC score 0.92 with data fusion.

Whether China’s State-Owned Commercial Banks Constitute “Public Bodies” within the Meaning of Article 1.1 (a) (1) of the Agreement on Subsidies and Countervailing Measures: Analysis of US—Definitive Anti-Dumping and Countervailing Duties on Certain Products from China  [PDF]

US—Definitive Anti-Dumping and Countervailing Duties on Certain Products from China is the initial WTO dispute in which China claims that US-countervailing duties on certain products from China are inconsistent with the obligations of the United States under the Agreement on Subsidies and Countervailing Measures (“SCM Agreement”). In this dispute, the specific meaning of “public bodies” within Article 1.1 (a) (1) of the SCM Agreement and the question of whether China’s state-owned commercial banks (“SOCB”) constitute “public bodies” are the heart of the matter. This thesis will analyze these issues by examining the reports of the Panel and the Appellate Body. In particular, the thesis will argue that the theory of the governmental function advanced by China is much more persuasive than that of governmental control in terms of defining “public bodies”. Although China’s SOCBs have gone through several stages of reforms, the majority ownership of them has remained in the hands of the Chinese government. However, SOCBs’ policy-oriented nature has been largely marginalized, and currently they only perform subsidiary governmental functions. In this regard, the conclusion this thesis will attempt to reach is that the WTO system needs to give developing countries like China more policy flexibility in order to upgrade their international trade participation to the level required and followed by developed countries. During the process, developing countries should also make the best use of their latent comparative advantage and the effects of globalization.
