Anti-N-methyl-D-aspartate receptor encephalitis is an autoimmune syndrome of central nervous system.The main clinical manifestations include psychiatric symptoms,movement disorders and seizures.It is often misdiagnosed as viral encephalitis.Tumors,especially the ovarian teratoma,play an important role in the disease.The prevalence in children is beyond imagination.Anti-NMDAR antibodies are specific diagnostic tests.Immune suppression is the main treatment.The first-line treatments include corticosteroids,intravenous immunoglobulin,and plasmapheresis.The second-line treatments include biological agents and cytotoxic drugs.Early diagnosis and treatment are essential for neurologic recovery.Overall prognosis is good.

Objective To investigate the effect of Tongxinluo capsule combined with metoprolol on elderly patients with coronary heart disease and angina pectoris and its influence on hemorheology and inflammatory factors.Methods 135 elderly patients with angina pectoris of coronary heart disease were selected,and they were randomly divided into treatment group (68 cases) and control group (67 cases).The treatment group was treated with Tongxinluo capsule combined with metoprolol,while the control group was treated with metoprolol.The two groups were treated for 8 weeks.The curative effect of the two groups was compared,the number and duration of angina pectoris,the changes of hemorheology and inflammatory factors before and after treatment were compared.Results The total effective rate of the treatment group (94.12％) was higher than 76.12％ of the control group (P ＜ 0.05).After treatment,the frequency and duration of angina pectoris in the treatment group were (6.03 ± 1.21) times/week and (3.02 ± 0.76) min/time,respectively,which were significantly lower than those in the control group [(9.87 ± 1.46) times/week and (4.86 ± 0.98) min/time] (t =16.649,12.201,all P ＜ 0.05).After treatment,the whole blood viscosity at high shear rate [(3.76 ± 0.41) mPa/s],whole blood viscosity in low shear [(8.13 ± 0.76) mPa/s],plasma viscosity [(1.23 ± 0.08) mPa/s],erythrocyte aggregation index [(2.06 ± 0.27)],fibrinogen [(2.46 ± 0.41) g/L] in the treatment group were lower than those in the control group[(4.53 ± 0.52) mPa/s,(9.61 ± 0.89) mPa/s,(2.09 ± 0.27) mPa/s,(2.63 ± 0.35),(3.53 ± 0.62) g/L] (t =9.562,10.396,25.170,10.604,11.844,all P ＜ 0.05).After treatment,the interleukin-6 (IL-6) [(8.49 ± 1.76) pg/mL],intercellular adhesion molecule-1 (ICAM-1)[(85.25 ± 8.92) pg/mL],C reactive protein (CRP) [(8.74 ± 1.76) mg/L] in the treatment group were lower than those in the control group[IL-6 (11.32 ± 2.10) pg/mL,ICAM-1 (103.42 ± 10.72) pg/mL,CRP (14.98 ± 2.24)mg/L] (t =8.491,10.712,18.012,all P＜0.05).Conclusion Tongxinluo capsule combined with metoprolol in the treatment of elderly patients with coronary heart disease angina pectoris has obvious curative effect,and can improve the patients'blood rheology and inflammatory reaction.

ObjectiveTo investigate the relationship between carotid atherosclerosis and progressing stroke.Methods103 patients with acute cerebral infarction within the first 24 hours from onset were tested with carotid color doppler ultrasonography during the first week from admission. Univariate and multiple logistic regression analyses were performed to examine the relationship between carotid intima media thickness (IMT), plaque structure, the degree of artery stenosis and the early deterioration of cerebral infarction.ResultsPrevalence of carotid plaque and thickness of IMT in patients with progressing stroke were higher than that in non progressing patients. In logistic regression, presence of carotid plaque was independent predictors of progressing stroke. Plaque size, extent of artery stenosis and IMT were not included in the regression model.ConclusionPlaque structure and its chemical feature may be the cause of progressing stroke.

As the most popular simplified model of the optical imaging system, the acquisition of the Gaussian point spread function (PSF) parameter is one of the hotspots and key points on which people do research in the field of image restoration. Based on the idea by which there exists deterministic mathematical relationship between Gaussian OTF feature points as well as its parameter and the frequency representation of the image in an existed literature, we proposed an automatic, accurate, stable, and improved approach. This method is able to give prominence to the related calculation feature by a Gaussian convolution and degeneration operation and finally realize the automatic esti mation of PSF parameter of a microscopic image. Experiments have proved that a good restoration result can be achieved utilizing the estimated PSF by the present method, which is of considerable application and reference value in restoration of other sorts with Gaussian approximate PSF model or 3D microscopic image restoration.

Coronal restoration of endodontically treated teeth may be viewed as one of the main parameters that influence the outcome of endodontic treatment. The purposes of restoring endodontically-treated teeth include preventing recontamination of the root canal system and periapical area, replacing the compromised dental hard tissue, restoring the coronal morphology and function, providing necessary strength for the restoration/tooth complex for functional stress, and avoiding crown and/or root fracture. This article reviewed recent researches on the restoration of endodontically treated teeth, provided evidence for clinical practice on topics as when to restore them, basic principles to be considered during treatment planning, and specific restoration options for both anterior and posterior teeth under different functional occulsal load conditions. Several issues should be taken into account during the decision making process, such as remaining tooth tissue, functional masticatory forces, comprehensive oral rehabilitation, and esthetic requirements.

AIM:To investigate the effects of tanshinone IIA ( Tan) on cardiac action potential in rats with a-cute cerebral ischemia (ACI).METHODS:ACI was established in rats accordingly .Animals were divided into 3 groups:sham group, ACI group, and ACI with Tan treatment group .The defect of neural function in each group was graded , elec-trocardiogram was measured , monophasic action potential was recorded , and the levels of cardiac troponin I ( cTnI ) and creatine kinase-MB ( CK-MB) were examined by commercially available kits .RESULTS:Compared with ACI group , Tan significantly decreased the scores of the defect of neural function , reduced the incidence and duration of the abnormalities in electrocardiogram , prolonged the effective refractory period , action potential duration at 50%repolarization and action po-tential duration at 90%repolarization, and inhibited the elevation of cTnI and CK-MB levels.CONCLUSION:Tan main-tains a stable heart rhythm in ACI rats , which may be related to its protective effect on ischemic myocardium .

Objective To investigate the effect of unilateral basal ganglia hemorrhage on long -term behavio-ral development of neonatal SD rats.Methods Forty -eight neonatal SD rats (1 0 days after birth)were equally divided into cerebral hemorrhage (CH)group,sham operation (SH)group and normal control (NC)group randomly, 1 6 cases for each group.Stereotaxic apparatus was used to inject autologous blood 25 μL into rats′brain caudate nu-cleus to establish basal ganglia hemorrhage model,while SH group was injected with nothing,and NC group received no treatment.Berderson scoring method was used to test rats′neurological functions on the first day,the third day,the seventh day,and the fourteenth day after operation,respectively.The open -field environment test and the Lat maze were used to assess behavior of the rats on the fourteenth day after operation,lasting for 3 days continuously.Results (1 )After being modeled rats appeared with different degrees of neurological function damage.SH group rats′neurologi-cal function damage was slight,which was completely restored in the 72 hours after surgery.CH group rats appeared hemiplegia and muscle tension change.CH rats neurological scores′on the first and third day after modeling scores were separate (3.40 ±0.83)scores and (1 .1 3 ±0.92)scores respectively,and the scores were statistically higher than SH group [(0.73 ±0.59)scores and (0.1 3 ±0.35)scores]and NC group (all P <0.05).And then Bederson score de-creased,and on the seventh and fourteenth day after modeling,the Bederson scores′difference was not statistically sig-nificant among the 3 groups(P >0.05).(2)On the fourteenth day after modeling,in open -field test and the Lat maze,the number of passed panels,straightening(times)and grooming(times)in CH group were more than those in SH group and NC group respectively (all P <0.05).The difference in the number of passed panels,straightening (times)and grooming (times)between SH group and NC group was not statistically significant (P >0.05 ). Conclusions Neonatal rats focal hemorrhage in unilateral basal ganglia is strongly repairable and compensatory,which leaves no severe neurological dysfunction.The neurological function damage which is caused by unilateral basal ganglia hemorrhage can lead to the increase of autonomic activities,the decrease of non -selective attention level,attention defi-cit and other long -term behavioral abnormalities.
