Objective To investigate the risk factors of restless leg syndrome (RLS) among male elders.Methods A case-control study between 148 old male RLS patients (case group) and 155 non-RLS male elders (control group) was conducted to investigate the risk factors of RLS.The general demographic data (age,education level,marital status,etc.),lifestyle (including physical exercise,smoking and alcohol) and past medical history were compared between two groups.Univariate analysis and non-conditional multivariate Logistic regression analysis was conducted by SPSS 13.0 software.Results In univariate analysis:there was significant difference in history of Parkinson disease between two groups [8.8％ (13/148)vs.3.2％ (5/155)] (P ＜0.05),but there was no significant difference in smoking,alcohol,physical exercise,history of diabetes mellitus and history of peripheral nerve disease between two groups (P ＞ 0.05).The serum creatinine in case group was higher than that in control group [(103.92 ± 32.07) μ mol/L vs.(85.35 ± 36.14) μ tmol/L] (P =0.000),and there was no significant difference in systolic blood pressure,diastolic blood pressure,hemoglobin,fasting blood glucose between two groups (P ＞ 0.05).Multivariate analysis showed that after adjusting for potential confounders,history of Parkinson disease and peripheral nerve disease,and serum creatinine was the independent risk factors of RLS among male elders.The values of OR(95％ CI) were 5.68(1.046-30.846),4.13(1.109-15.368),1.02(1.014-1.036),respectively.Conclusion Histories of Parkinson disease and peripheral nerve disease and serum creatinine are the independent risk factors of RLS among male elders.

Objectives To investigate the clinical feature of Parkinson's disease (PD) with restless leg syndrome (RLS) and the pathogenesis of RLS. Methods We conducted a cross-sectional and control study. The case group concluded 31 PD with RLS patients, meanwhile 39 PD patients were selected as the control group. Clinical history, clinical manifestations, complications and laboratory examinations were compared respectively between the two groups. Results All the RLS symptoms did not appear in RLS patients until the PD symptoms came out. Significant differences were found in complications such as swallow disturbance, constipation and illusion, when we compared the two PD groups (P ＜ 0.05 ). Compared with the PD or healthy group, the level of serum ferritin and the H-reflex latency of tibial nerve were significantly decreased in PD with RLS group ( P＜0.05). Conclusions Secondary RLS is a complication of PD.Deficiency of iron and decreased inhibition function of spinal cord may lead to the occurrence of RLS in PD patients. When their motor symptoms are serious and complications are more common, PD patients are more possible to have RLS symptoms.

ObjectiveTo assess the value of the area of ground glass opacities (GGOs) in lungs displayed by high-resolution computed tomography (HRCT) in paraquat (PQ) poisoned patients in evaluating prognosis. Methods Clinical and imaging data of 137 patients with acute PQ poisoning admitted to Affiliated Hospital of the Medical College of Chinese People's Armed Police Forces from January 2012 to August 2014 were analyzed retrospectively. The plasma concentration of PQ on admission and the area of GGOs were compared between two groups. The lung HRCT within 10 days of poisoning was performed every 3 days, and the areas of GGOs were evaluated on five levels, including aortic arch, aortic pulmonary window, left upper lobe bronchial, right inferior pulmonary vein, and left diaphragmatic dome. Receiver operating characteristic curve (ROC) was plotted to evaluate the value of all the parameters for prognosis.Results Among 137 patients, 45 died within 28 days after poisoning, with the mortality rate of 32.85%. The plasma PQ level in the non-survivors was significantly higher than that in the survivors (mg/L:7.06±0.67 vs. 3.51±0.34,t = 5.280,P = 0.000). The areas of GGOs at three time points in the non-survivors were significantly higher than those in the survivors [1-3 days: (32.0±5.0)% vs. (2.5±0.4)%,t = 7.860,P = 0.000;4-6 days: (45.5±5.7)% vs. (2.8±0.5)%,t = 12.420,P = 0.000; 7-10 days: (68.0±4.8)% vs. (3.0±0.6)%, t = 23.950,P = 0.000]. ROC analysis demonstrated that the area under the ROC curve (AUC) of GGOs in 7-10 days was 1.000, which could be used to determine the prognosis, but it was too late for the treatment. The AUC of GGOs in 4-6 days was 0.979, with the threshold of> 12.0%, the specificity of 96.15%, the sensitivity of 85.19%, the positive predictive value of 88.46%, and the negative predictive value of 94.94%, which presented good effect in predicting prognosis in the early stage of acute PQ intoxication. But plasma PQ concentration was relatively poor for determining prognosis, AUC was 0.821, with the threshold of> 1.95 mg/L, the specificity of 34.52%, the sensitivity of 88.64%, the positive predictive value of 41.49%, and the negative predictive value of 85.29%.Conclusions The area of GGOs displayed by HRCT can be used to evaluate the fully developed acute PQ lung injury, and it is superior to plasma PQ concentration. The area of GGOs displayed by HRCT 4-6 days after intoxication can be used for the evaluation of PQ induced pulmonary injury in the early stage and the evaluation of clinical prognosis.

OBJECTIVE:To observe the efficacy and safety of oxaliplatin,mitomycin and doxorubicin combined with three-di-mensional conformal radiotherapy for patients with lack of blood supply hepatocellular carcinoma. METHODS:62 patients with lack of blood supply hepatocellular carcinoma who lose the opportunity of operation were randomly divided into control group(31 cas-es)and observation group(31 cases). Control group received puncture through the femoral artery by Seldiner,selectively interven-ing in hepatic arteries for DSA angiography,then intravenously injected 130 mg/m2 Oxaliplatin for injection via the catheter,once every 2 weeks+Mitomycin for injection 10 mg,intravenously,once every 1-3 week(s)+Doxorubicin for injection 1.2 mg/kg,once every 3 weeks,then giving Iodinated oil emulsifier and Gelatin sponge particle for hepatic artery embolization,appropriate Iodinat-ed oil emulsifier and Gelatin sponge particle once a month,for 3 times. Observation group was additionally received three-dimen-sional conformal radiotherapy 2 Gy,for 25-30 times with total dose of 50-60 Gy,once every 3 days. They were treated for 3-month. Clinical efficacy,the survival rate and median survival time after the first administration of drug for 1,2 and 3 years in 2 groups were observed,and the incidence of adverse reactions was recorded. RESULTS:The total effective rate,the survival rate and median survival time in 1,2 and 3 years in observation were significantly higher than control group,with statistical signifi-cance (P<0.05). The incidences of neutropenia,thrombocytopenia,hemoglobin decreased and radioactive disease in observation group were significantly higher than control group,with statistical significances(P<0.05). CONCLUSIONS:Oxaliplatin,mitomy-cin and doxorubicin combined with three-dimensional conformal radiotherapy have good efficacy for patients with hepatocellular lack of blood supply carcinoma,also can prolong the survival time,they show poor safety.

White matter hyperintensities (WMHs) is a magnetic resonance imaging phenotype of cerebral small vessel disease,which is manifested as diffuse or confluent subcortical white matter.There is usually no clinical manifestation in the early stage of WMHs,and its pathophysiological mechanism has not been fully elucidated.Studies have shown that a variety of factors are associated with WMHs.The article reviews the risk factors for WMHs.

The clinical data and imaging findings of 10 patients with reversible splenial lesion syndrome ( RESLES ) admitted in Shanxi people′s Hospital from August 2014 to August 2016 were retrospectively analyzed .All 10 patients were acute or subacute onset , the etiology included viral meningitis ( n =5 ) , purulent meningitis ( n =2 ) , tuberculous meningitis ( n =1 ); and one schizophrenic patient receiving antipsychotic drug and one epileptic patient treated with phenytoin .There were 8 patients under 30 years.The clinical manifestations included headache , fever, disorder of consciousness and mental symptoms.Seven patients had prodromic infections before the onset of the disease and focal neurological defects were present in the early stage .The initial MRI showed isolated splenium of corpus callosum (SCC) lesions with homogeneous hyperintense on T 2WI, hypointense on T1WI, and patchy, round, ovoid, schistose diffusion with hyperintense on DWI in all 10 cases;and there was no significant strengthening on enhanced MRI in 4 cases.The follow-up MRI showed that SCC abnormalities disappeared after treatment in 9 cases and the neurological symptoms disappeared after one-month follow up in 6 cases.The results indicate that RESLES is frequently secondary to infections , and presents the symptoms of mild encephalitis or encephalopathy .

Stroke is one of the main causes of adult disability and death, and ischemic stroke is the most common type of stroke. Therefore, it is of great significance to evaluate the condition and outcome of patients with ischemic stroke timely and accurately. As a cheap, non-invasive and multi-functional technology, electroencephalogram (EEG) can directly reflect the abnormal state of brain function and metabolism, and is more sensitive to brain damage caused by the decreased cerebral blood flow. It has important significance in predicting the outcome of patients with ischemic stroke. This article reviews the changes of EEG after ischemic stroke and the characteristic EEG changes related to the outcome of ischemic stroke.

White matter hyperintensities (WMHs) are one of the MRI markers of cerebral small vessel disease, which are more common in the elderly, and are closely associated with the clinical manifestations such as cognitive impairment and gait disorder, however, the pathophysiological mechanism is currently unclear. This article expounds the possible pathophysiological mechanisms of WMHs from many aspects, such as hypoperfusion, blood-brain barrier destruction, oxidative stress, inflammation, and genetics.

Cerebral edema and its caused elevated intracranial pressure are one of the main causes of death in patients with acute ischemic stroke. The main pathogeneses of brain edema include cytotoxic edema, ionic edema, and angiogenic edema. At present, the treatment strategies used to control brain edema and reduce intracranial pressure are mainly osmotic drugs and hemicraniectomy decompression, which are symptomatic treatments to reduce intracranial pressure. In recent years, it has been proposed to inhibit the ion channel in the formation of brain edema as a therapeutic target, which provides a new direction for the treatment of brain edema.
