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.

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.

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.

Objective To study the changes in the content of elements in Aedes albopictus after dengue virus typeⅡ(DV2) infection. Methods DV2 were injected into the thorax of Ae.albopictus . The content of elements in Ae. albopictus was determined on days 5, 10 and 20 after infection respectively and compared with those in the same instar non infected mosquitoes. Results and Conclusion For the group of day 5 after DV2 infection, the content of elements Ca, S and Cr increased remarkably compared to those in the control group; while the content of elements Zn, Mo, Pb, Ce and Cl reduced remarkably. For the group of day 10 after infection, the content of Na, Mg, Zn, Se, Ce and S increased remarkably compared to those in the control; only that of Fe was lower remarkably than the control. For the group of day 20 after infection, the content of elements Ti and Pb increased remarkably than that of the control; while the content of Na, Zn, Cr and Ce reduced remarkably.

MRI is a powerful noninvasive imaging tool. Multispectral MRI sequences have been validated to characterize atherosclerotic plaque components, size, thickness and vulnerable plaque in animals and humans. Developments of intravascular MRI (IVMRI) may play an important role in this regard. MRI contrast agents may identify inflammation and thrombus within atherosclerotic plaque. MRI has progressed to be used in serial studies of atherosclerotic plaque progression and regression in the face of therapeutic intervention.

Objective To study the maneuver of diagnosis and management of anterior cruciate ligament (ACL) partial tears. Methods 24 cases of ACL partial tears confirmed by arthroscopy including anteromedial band (AMB) tear in 7 cases and posterolateral bulk (PLB) tear in 17 cases were investigated, from Mar 2000 to Jun 2002. ACL reconstruction was performed in 16 cases under arthroscopy. Clinical findings including symptoms or signs, physical examinations and MRI were collected for differential diagnosis of AMB and PLB tear. The efficiency of ACL reconstruction was evaluated by Lysholm scale with average follow-up of 11 months. Results 28.5% AMB and 98.2% PLB tear cases showed knee instability. Regarding the results of anterior drawer test, Lachman test and pivot shift test, it is positive 71.4%, 14.3% and 0 in AMB tears respectively; and 17.6%, 98.2%, 76.5% in PLB tears. The Lysholm scores were significantly increased from preoperative 63.53?8.11 to postoperative 93.47?2.62(P
