Stroke is the disease which caused by many risk factors.The relationship between insulin resistance(IR) and young adult stroke is one of the focuses now in the neurological field.IR refered to the series of pathological and physiological changes,it happens when the response of the target tissue organ to insulin is depressing or losing.There are many ways of detection of IR,the insulin sensitivity index(ISI) is one of the most satisfied indexes to reflect the sensitivity to insulin.IR could cause a series of pathological and physiological changes,which caused hyperinsulinemia,hyperglycemia,hyperpiesia,blood-fat derangement,fibrinolytic system anomaly,blood vessel endothelium change,artherosclerosis,et al,maybe in ways of many metabolic risk factors.Atherosclerosis is the main etiopathogenisis factor in young adult stroke,as a conclusion,IR is also existed in young adult stroke.But,does IR exist in all types of young adult stroke? What is the mechanism? Is the level of IR related with the pathogenetic condition and prognosis? These questions are still not clear at present,and the study on the relationship between IR and young adult stroke is important to prevent young adult stroke.

Objective To investigate the changes of cardiac structure and function in patients with hepatolenticular degeneration (HLD).Methods From March 2010 to February 2011,90 HLD patients who did not receive formal treatment (observation group) and 30 healthy people (control group) were collected and analyzed with color Doppler echocardiography in the Institute of Neurology,Affiliated Hospital of Anhui University of Traditional Chinese Medicine.Based on the clinical manifestations,cases were divided into hepatic type group (n =31),brain type group (n =42) and brain-visceral type group (n =17).According to the Child-Pugh classification,patients were divided into Child A group (n =71),Child B group (n =10) and Child C group (n =9).Results (1) The left atrial diameter ((28.00 ± 3.11),(29.62 ± 3.44) mm) and left ventricular diameter ((45.69 ± 3.75),(47.10-± 4.73) mm) of HLD patients in brain-visceral type group and hepatic type group were larger than that of the control group ((24.86 ± 2.63),(41.93 ±3.56) mm;t =3.143,4.761,P=0.018,0.000;t=3.764,5.167,P=0.018,0.000).The left atrial diameter and left ventricular diameter of hepatic type group were significantly larger than the brain type group (26.06 ± 3.68,43.34 ± 3.88;t =3.557,P =0.000;t =3.751,P =0.001).The value of E/A in the hepatic type group (1.57 ± 0.37) was significantly lower than the control group (1.93 ± 0.20;t =-0.352,P =0.006).(2) The left atrial diameter ((31.29 ± 1.70),(34.67 ± 1.97) mm) and left ventricular diameter ((48.29 ± 2.81),(53.67 ± 2.67) mm) of Child B and C groups were significantly larger than the control group ((24.86 ± 2.63),(41.93 ± 3.56) rm;t =6.429,9.810,P =0.000,0.000;t =6.357,10.738,P =0.000,0.000),and the Child A group ((26.42 ± 3.05),(43.89 ± 3.76) rm;t=4.871,8.252,P=0.000,0.000;t =4.399,8.780,P=0.003,0.000).The value of E/A of Child B and C groups (1.58 ± 0.32,1.26 ± 0.39) was lower than that of the control group (t =-0.347,0.662,P=0.020,0.000);At the same time,the value of E/A of Child C group was significantly lower than that of Child A group (1.80 ± 0.33;t =-0.530,P =0.000).Conclusions The HLD patients may have cardiac structural and functional changes,mainly manifested as left atrial and left ventricular enlargement and cardiac diastolic dysfunction,whereas a serious impact has not yet been found in systolic function.And the changes of cardiac structure and function were related to the degree of liver cirrhosis in patients with HLD.

Objective To investigate the relationship and mechanism of the heme oxygenase-1 expression in peripheral blood mononuclear cells (PBMC) and the oxidative stress in diabetic nephropathy. Methods Two groups of diabetic patients with or without diabetic nephropathy and a normal control group were enrolled in this study. Fasting blood glucose (FBG), HbA1c, serum MDA level, ROS level, HO-1 mRNA level and HO-1 protein expression in PBMC were determined. Results In control group, diabetic group and diabetic nephropathy group , the MDA levels significantly increased[(14.23±5.07)nmol/ml vs (24.90±7.12)nmol/ml vs (43.83±16.97)nmol/ml](F＝37.022,P＜0.01), the ROS levels significantly increased (113.18±58.59 vs 364.54±88.67 vs 524.35±162.51)(F＝68.369,P＜0.01) and the HO-1 protein expression also increased significantly (22.84±9.98 vs 36.72±15.85 vs 58.1±15.93)(F＝31.302,P＜0.01). There was a positive correlation among the HO-1 mRNA, protein expression and MDA level(r＝0.407,0.429,P＜0.05). Conclusions There existed a severer oxidative stress condition in patients with diabetic nephropathy compared with the patients without diabetic nephropathy. HO-1 could be a potential pathway to ameliorate oxidative stress in diabetic kidney disease patients.

Objective To retrospectively analyze the prognostic factors for locoregionally recurrent early?stage extranodal nasal?type natural killer/T?cell lymphoma ( NKTCL) . Methods A total of 56 patients with early?stage extranodal nasal?type NKTCL, who had locoregional recurrence after initial treatment and then received salvage treatment from 1995 to 2014, were enrolled as subjects. The effects of salvage treatment on the overall survival ( OS) rate were analyzed after initial treatment and recurrence. Univariate and multivariate prognostic analyses were performed on the OS rate after recurrence. Results The median follow?up time was 35. 9 months after initial treatment and 14. 8 months after recurrence. The 3?year OS rate was 73% after initial treatment and 58% after recurrence. Compared with chemotherapy alone, radiotherapy?containing salvage treatment significantly improved the OS rates after initial treatment and recurrence ( P=0. 040, 0. 009 ) , and re?irradiation also significantly improved the OS rates after initial treatment and recurrence (P=0. 018, 0. 019). Most (84%) of the acute and late adverse reactions after re?irradiation were grade 1?2 ones. The univariate and multivariate analyses showed that the Karnofsky Performance Status score, radiotherapy in initial treatment, and radiotherapy in salvage treatment were influencing factors for the OS rate after recurrence. Conclusions Radiotherapy achieves improved survival and tolerable toxicities, making it indispensable in the treatment of locoregionally recurrent extranodal nasal?type NKTCL.

Based on ancient literature of acupuncture in Canon of Chinese Medicine (4th edition), the articles regarding acupuncture for urinary incontinence were retrieved and collected to establish a database. By Weka data mining software, the multi-level association rules analysis method was applied to analyze the acupoints selection characteristics and rules of ancient acupuncture for treatment of urinary incontinence. Totally 356 articles of acupuncture for urinary incontinence were collected, involving 41 acupoints with a total frequency of 364. As a result, (1) the acupoints in the yin-meridian of hand and foot were highly valued, as the frequency of acupoints in yin-meridians was 2.6 times than that in yang-meridians, and the frequency of acupoints selected was the most in the liver meridian of foot-jueyin; (2) the acupoints in bladder meridian of foot-taiyang were also highly valued, and among three yang-meridians of foot, the frequency of acupoints in the bladder meridian of foot-taiyang was 54, accounting for 65.85% (54/82); (3) more acupoints selected were located in the lower limbs and abdomen; (4) specific acupoints in above meridians were mostly selected, presenting 73.2% (30/41) to the ratio of number and 79.4% (289/364) to the frequency, respectively; (5) Zhongji (CV 3), the front-mu point of bladder meridian, was seldom selected in the ancient acupuncture literature, which was different from modern literature reports. The results show that urinary incontinence belongs to external genitalia diseases, which should be treated from yin, indicating more yin-meridians be used and special acupoints be focused on. It is essential to focus inheritance and innovation in TCM clinical treatment, and applying data mining technology to ancient literature of acupuncture could provide classic theory basis for TCM clinical treatment.

ObjectiveTo study the CT values of certain phantoms scanned by various CT scanners with dissimilar parameters.Methods The CT values of tissue equivalent inserts was measured in the TM164 and CIRS-062 phantom scanned by TOSHIBA AQUILIONTM,SIEMENS SOMATOMTMSENSATIONTM 64 and SIEMENS SOMATOMTM SENSATIONTM OPEN with different voltages,currents and slice thicknesses and then the corresponding CT-to-density curves was compared. Results There are no significant differences of CT values with various currents and slice thicknesses and also for low atom number materials scanned by different scanners with various tube voltages.The CT values of high atom number materials have obvious differences scanned with tube voltage,the maximum is about 400 HU.There are also significant differences between CT-density curves of two phantoms in the range from soft tissues to dense bone,the maximum is up to 500 HU.ConclusionsCT-density curves were highly affected by materials of phantoms,scanners and tube voltages.It is necessary to measure the curve with a comfortable phantom and certain scanner to assure the accuracy for dose calculation for treatment planning system.

The specific anti-tumor immune response induced by mouse bone marrow dendritic cells (DCs) transfected with recombinant adenovirus carrying mutant k-ras genes was investigated. DCs were generated from mouse bone marrow in the presence of rmGM-CSF (3.3 ng/mL) and rmIL-4 (1.3 ng/mL) and detected by FACS, and then transfected with the recombinant adenovirus encoding mutant k-ras gene. The efficacy of transfection and T cell stimulating activity of DCs were detected. CTL activity of the mice vaccinated with DCs was observed. The results showed that DCs had dendritic veiled morphology. BmDCs highly expressed B7-1 (80 %), B7-2 (77 %), MHC Ⅱ (70 %), CD11c (65 %), CD40 (70 %) and CD54 (96 %) with FACS, and no significant difference in the expression was observed before and after the transfection (P>0.05). The DCs transfected by mutant k-ras gene could significantly stimulate lymphocytes proliferation as compared with those transfected by Ad-c or non-modified DCs (P<0.05). DC vaccine transfected by mutant k-ras gene could induce CTL activity against Lewis lung cancer, but not against B16. The specific cytotoxicity against Lewis lung cancer in Ad-k-ras/12-transduced DC group was significantly higher than those in the control, vector and non-transfected DCs groups (P<0.05). It was concluded that special antitumor response could be induced by DCs transfected with recombinant adenovirus carrying mutant k-ras genes.

Objective To analyze the clinical features,risk factors,imaging features and prognoses of cerebral infarction menifested as isolated acute vestibular syndrome (AVS) to improve the diagnoses and treatments of the disease.Methods Clinical data of 15 cerebral infarction patients menifested as isolated AVS,admitted to our hospital from October 2015 to April 2016,were summarized retrospectively.The clinical features,risk factors,imaging features and prognoses of these patients were analyzed.Results (1) Clinical characteristics:the average age of cerebral infarction patients menifested as isolated AVS was 62.1 ±13.5 years old,and the median attack time was 24 (4-168) h;the main clinical manifestations were vertigo,including nausea (n=1 1),vomiting (n=10),nystagmus (n=10),and unstable gait (n=14).(2) Risk factors:14 patients had multiple risk factors of stroke (＞4),and they were age,hypertension,hypedipidemia,diabetes,smoking,carotid stenosis,history of stroke,white matter degeneration,coronary heart disease,and atrial fibrillation.(3) Imaging features:14 patients were posterior circulation infarction,and the lesions were located in the cerebellar hemisphere (n=l 1),cauda cerebelli (n=4),pons (n=3),brachium pontis (n=1),brachium inferius cerebelli (n=1);inferior colliculus (n=1),and multiple lesions occurred in 6 patients;one anterior circulation infarction was located in the insula;most lesions were smaller lacunar infarcts,but the lower part of cerebellar hemisphere was mostly larger infarct.(4) Prognoses:the prognosis of patients is good after regular treatment,9 had complete symptom relief,and 6 got improvement.Conclusions When patients presented with isolated AVS and many risk factors exist in clinic,the possibility of cerebral infarction should be taken into account.Such patients should be subjected to relevant examinations in a timely manner and early diagnosis,so that they can get regular treatment as soon as possible and prognoses can be improved.
