@#A middle-aged male patient,had the chief complaint of recurrent lower limb weakness,and he was misdiagnosed with chronic inflammatory demyelinating polyradiculoneuropathy. Later the patient attended the hospital again due to lower limb weakness,recurrent headache,and nausea and vomiting. The cerebral magnetic resonance imaging showed diffuse restricted high-signal lesions at the bilateral cerebral corticomedullary junctions; immunohistochemical staining showed that inclusion bodies strongly stained with P62 and ubiquitin antibodies were observed in the nuclei of some sweat gland cells,adipocytes,and fibroblasts; genetic testing showed 142 times of the abnormal amplification of GGC in the NOTCH2NLC gene. Therefore,a confirmed diagnosis of neuronal intranuclear inclusion disease (NIID) was made. This case suggests that we should pay attention to whether the central nervous system is involved when peripheral neuropathy is observed.

@#Objective To observe the incidence of white matter hyperintensities (WMHs) and the distribution of right to left shunt (RLS) in migraine patients,and to explore whether WMHs is related to RLS. Methods 106 patients with migraine were selected as the research objects. The basic data and clinical information of migraine were collected. The WMHs were evaluated by cranial MRI. The RLS was diagnosed and graded by transcranial Doppler (TCD) bubbles test. The correlation between WMHs and RLS was analyzed. Results Among 106 migraine patients,33 (31.1%) were in WMHs+ group and 73 (68.9%) in WMHs- group. The total positive rate of RLS was 48.1% (51/106). The distribution of different shunt levels was as follows:grade Ⅰ shunt in 27 cases (25.5%),grade Ⅱ shunt in 4 cases (3.8%),grade Ⅲ shunt in 6 cases (5.6%),grade Ⅳ shunt in 14 cases (13.2%). In "WMHs+" group,there were 5 cases of grade Ⅰ shunt,1 case of grade Ⅱ shunt,3 cases of grade Ⅲ shunt and 10 cases of grade Ⅳ shunt;in "WMHs-" group,there were 22 cases of grade Ⅰ shunt,3 cases of grade Ⅱ shunt,3 cases of grade Ⅲ shunt and 4 cases of grade Ⅳ shunt. Compared with "WMHs+" group and "WMHs-" group,there was no statistical difference in the overall positive rate of bubbles test between the two groups (P>0.05,χ2=1.719),but the large shunt rate of "WMHs+" group was significantly higher than that of "WMHs-" group (P<0.01,χ2=13.188). Conclusion There is no significant correlation between WMHs and RLS in migraine patients,but large RLSs will increase the risk of WMHs in migraine patients.

Abstract Purpose: To investigate whether oxymatrine (OMT) prevents hepatic fibrosis in rats by regulating liver transforming growth factor β1 (TGF-β1) level. Methods: Hepatic fibrosis was induced in rats by thioacetamide (TAA). Blood was collected at the end of week 12 to determine the levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), and glutathione (GSH). Changes in liver tissue were observed after hematoxylin-eosin (HE) staining. Results: Fibrosis was confirmed by Masson's collagen staining. Liver TGF-β1 level was determined by ELISA. OMT significantly reduced serum ALT and AST but increased GSH levels in rats with hepatic fibrosis. Moreover, it significantly improved liver histology in rats with TAA-induced hepatic fibrosis. It significantly decreased liver TGF-β1 level compared to that in the untreated group. It also significantly reduced collagen deposition in rats. Conclusion: Oxymatrine is effective in protecting rats from thioacetamide-induced hepatic fibrosis by regulating TGF-β1 expression.

Chinese materia medica (CMM) has the multi-component, multi-target, and multi-pathway characteristics, which are coincided with the theory of network pharmacology. Therefore, applying network pharmacology to CMM researches will be helpful to explain the effects of CMM in the treatment of complex diseases holistically and systematically. In this paper, the recent progress in the applications of network pharmacology in CMM studies has been reviewed, including prediction and identification of targets and core bioactive components, clarification of the mechanism of action, explanation of the prescription composition rules, development of new indications, discovery of new active compounds and the combined application of network pharmacology and omics technologies, so as to accelerate the extensive applications of this new technology.

Objective To study the prevalence,treatment policy and control of hypertension in patients with maintenance hemodialysis, and to analyze the influencing factors of hypertension control.Methods We studied the current status of 1382 patients with maintenance hemodialysis in 11 dialysis centers in Shanghai, among them 809 were male, and 573 were female.Hypertension was defined as systolic blood pressure(SBP) ≥ 140 and/or diastolic blood pressure (DBP) ≥90 mm Hg ( 1 mm Hg = 0.133 kPa).Those who had a history of hypertension and requiring antihypertensive therapy were also diagnosed as hypertension though their blood pressure was within normal range during the survey.Hypertension control was defined as blood pressure < 140/90 mm Hg before each dialysis session.Results The prevalence of hypertension in the hemodialysis patients was 86.3%.The treatment rate and control rate in those patients were 96.8% and 25.5% respectively.More than half (50.4% ) of patients were treated with only one kind of anti-hypertensive drug, and 34.4% with 2 kinds, 14.2% with 3 kinds, 1.0% with 4 kinds or more.Calcium channel blocker (CCB) was the most frequently prescribed drug (61.0%), followed by angiotensin Ⅱ receptor blockers ( 56.4% ), centrally acting anti-hypertensive agent ( 26.4% ), beta blockers and alpha, beta-blockers( 14.0% ).The control rate of hypertension in those hemodialysis people was aggravated by the existence of coronary artery disease.The patients who need more kinds of antihypertensive agents have a poorer control rate of hypertension.The hypertension control rate elevated significantly with the adequate hemodialysis.Conclusions There is a very high prevalence of hypertension in maintenance hemodialysis patients.Although the treatment rate is high, the control rate is unsatisfactory.So the control of hypertension in hemodialysis patient is still a clinical challenge.Appropriate dialysis adequacy, reasonable use of erythropoietin, treatment of heart disease and judicious use of antihypertensive drugs may be helpful to improve the clinical outcome.

Objective To investigate the effect of blood pressure management on perihematomai edema in patients with acute hypertensive intracerebral hemorrhage. Methods The retrospective research method was used to conduct logistic regression analysis for the factors of age, number of days, antihypertensive drugs, dehydrating agents, and blood pressure in inpatients with hypertensive intracerebral hemorrhage from June 2005 to December 2007. Results Multivariate analysis found that both amlodipine (OR = 0. 208, 95% CI 0. 063-0. 684) and angiotensin-converting enzyme inhibitor (ACEI) (OR = 0. 280, 95% CI 0. 085-0. 920) were the protective factors for perihematomal edema; both the course of 10 to 20 days (OR =7.413, 95% CI 1. 362-40. 360) and poorly controlled diastolic blood pressure (OR = 6. 449, 95% CI 1. 011-41. 145) were the risk factors for perihematomal edema. Conclusions Amlodipine and ACEI may lower the risk of perihematomal edema in intracerebral hemorrhage, while the poorly controlled diastolic blood pressure and the course of 10 to 20 days are the risk factors for perihematomal edema.

Objective To propose an automatic framework for segmentation of brain image in this paper. Methods The brain MRI image segmentation framework consists of three-step segmentation procedures. First, Non-brain structures removal by level set method. Then, the non-uniformity correction method is based on computing estimates of tissue intensity variation. Finally, it uses a statistical model based on Markov random filed for MRI brain image segmentation. The brain tissue can be classified into cerebrospinal fluid, white matter and gray matter. Results To evaluate the proposed our method, we performed two sets of experiments, one on simulated MR and another on real MR brain data. Conclusion The efficacy of the brain MRI image segmentation framework has been demonstrated by the extensive experiments. In the future, we are also planning on a large-scale clinical evaluation of this segmentation framework.

Objective To present a novel modified level set algorithm for medical image segmentation. Methods The algorithm is developed by substituting the speed function of level set algorithm with the region and gradient information of the image instead of the conventional gradient information. This new algorithm has been tested by a series of different modality medical images. Results We present various examples and also evaluate and compare the performance of our method with the classical level set method on weak boundaries and noisy images. Conclusion Experimental results show the proposed algorithm is effective and robust.
