【摘要】 目的 探讨急性脑梗死溶栓治疗的疗效及安全性。 方法 2004年1月-2009年5月58例急性脑梗死患者，按接受尿激酶治疗时已发病时间分为3组，均接受尿激酶150万U加生理盐水150 mL静脉滴注溶栓治疗。分别在治疗后0、1、3、9 h进行神经功能评价，1、3、7 d进行神经功能评价及复查头颅CT。 结果 发病3 h内与发病3~6 h内溶栓治疗效差异无统计学意义（Pgt;0.05）；发病3 h内、3~6 h内与发病6~9 h尿激酶溶栓治疗疗效差异均有统计学意义（Plt;0.05）；发病6~9 h尿激酶溶栓治疗疗效差，多例并发脑出血，安全性差。 结论 发病6 h内的脑梗死患者，只要无禁忌证均应尽快行尿激酶溶栓治疗；发病6 h后的脑梗死患者，不宜尿激酶溶栓治疗；伴房颤者的溶栓治疗因样本量过小研究无意义，有待进一步研究。【Abstract】 Objective To discuss the efficacy and safety of thrombolytic therapy for acute cerebral infarction. Methods A total of 58 patients with acute cerebral infarction from January 2004 to May 2009 were enrolled in this study. Based on the onset time before accepting urokinase treatment, the patients were divided into three groups. All of them accepted thrombolytic treatment with 1.5 million U of urokinase and 150 ml of saline solution intravenously. Neurological function evaluation was carried out 0, 1, 3, and 9 hours after the treatment. Another neurological function evaluation and skull CT were done 1, 3, and 7 days later, respectively. Results There was no statistical difference between the efficacy of the treatment within 3 hours and between the 3rd hour and the 6th hour after the onset of the disease. However, there was a significant difference between the efficacy within 3 hours and between the 6th and 9th hour, and between the efficacy from the 3rd hour and 6th hour and from the 6th hour and the 9th hour after the onset of the disease. Between the 6th and the 9th hour after the onset, the efficacy and safety were poor with many cases of combined cerebral bleeding. Conclusions For patients within 6 hours after the onset of cerebral infarction, as long as no contraindications exists, thrombolytic therapy should be carried out as soon as possible; 6 hours after the onset, patients should not be treated with thrombolytic therapy. Further study is needed for patients combined with atrial fibrillation due to the small sample size in this study.

Methods From January, 1999 to January, 2010, 42 inpatients with acute disseminated encephalomyelitis were collected and their clinical data were analyzed retrospectively. Results Out of these 42 patients, 11 (26.19% ) were within 5 to 14 years, 20 (47.62%) ithin 15 to 40 years; 23 (54.76%) had definite infection, and 15 (35. 71%)had no any causes; 23 (23/34, 67.65%) had abnormal cerebrospinal fluid; 27 (27/32, 84.38%) had abnormal electro-encephalograph; 26 (26/40, 65.00%) were CT positive, 25 (25/28, 89.29%) MRI positive; corticosteroids and gamma globulin were effective in the treatment of disseminated encephalomyelitis. Conclusion Acute disseminated encephalomyelitis is a kind of inflammatory disease with various clinical manifestation and mediated by immune. Cerebrospinal fluid, MRI, and electro-encephalograph have important roles in its diagnosis. Large dose of corticosteroids and gamma globulin are effective in the treatment of acute disseminated encephalomyelitis.
Objective To quantitatively evaluate the effect of 2 types of pressures induced injury by using threedimensional (3D) reconstruction of rats loaded tibial is anterior muscle from two-dimensional (2D) image of serial histological sections. Methods Twenty female or male Sprague Dawley rats, aged 10-12 weeks and weighing 280-300 g, were randomlydivided into experimental group (n=10) and control group (n=10). The random side of tibial is anterior muscle was givenintermittent gradient (8.0-21.3 kPa) and sustained (13.3 kPa) pressure in 0.12 cm2 area in experimental group and controlgroup, respectively; the experiment was terminated and the general condition of rats was observed after 3 cycles, and a single cycle included 2 hours of compression and 30 minutes of release. The general observations of pressed skin and tibial is anterior muscle were done after 24 hours of pressure rel ief, and the tibial is anterior muscle was harvested integrally from the loaded side, then made into interval 4 μm serial sections. After HE staining, 2D images were obtained. Necrosis and injury areas were distinguished by Image Pro Plus (IPP) 6.0 software and image registration was conducted by Photoshop 8.0.1 after 2D panorama images acquired by digital microscope (× 40) and IPP mosaic software. 3D reconstruction was establ ished via data processing using Mimics 10.1 software so as to get the volume, the surface area, and 3D images of the whole piece of tibial is anterior muscle and injury areas respectively. Results All rats of 2 groups survived till experiment terminated and no skin ulcers occurred after 24 hours. Edema and indentation were observed on press side skin and tibial is anterior muscles of 2 groups, fadeless maroon area was observed in control group. A total of 994 sl ices were obtained from 20 samples of tibial is anterior muscles. 3D images suggested that injury of control group was severe, which penetrated the whole piece of tibial is anterior muscle and expandedalong the tibia bony prominence. By contrast, injury of experimental group was less, but had similar width to the contact surface of indentor. There was no significant difference in the volume and the surface area of tibial is anterior muscle between 2 groups (P gt; 0.05), while the injury volume and the injury surface area were significantly smaller in experimental group than in control group (P lt; 0.05). Conclusion 3D reconstruction is an effective method to quantitatively evaluate pathological changes inside the integrity tissue and can provide the visual basis for the mechanical property distributed in the loaded muscle. Intermittent gradient pressure can reduce deep tissue injury.
Objective To identify the best therapy regimen for a patient with rare chronic leg ulcer in necrobiosis lipoidica diabeticorum (NLD). Methods We searched the Cochrane Library (Issue 3, 2006), PubMed (1966-July 2006), EMbase (1974-July 2006) and CBM (1978-July 2006) to identify relevant evidence. The quality of the retrieved studies was critically assessed. Results A total of 153 records were retrieved. No clinical guidelines, systematic reviews or clinical randomized studies were identified. Thirty treatment-related studies involving 17 interventions showed that, fumaric acid esters, oral pentoxifylline, topical use of growth factors and surgical skin flap transplant were relatively more effective and safer than conventional therapies. Conclusion After treatment with tropical granulocyte colony-stimulating factor, the patient with chronic leg ulcers was healed.
Objective To compare the effect of two types of intermittent pressure on formation of pressure ulcer in rabbit hind l imbs and to investigate the mechanism of gradually changed intermittent pressure produced by waves bed in the prevention of pressure ulcer. Methods Gracil is (3 cm2) in both hind l imbs of 12 adult Japanese white rabbits were randomlyloaded with gradually changed intermittent pressure (50-160 mm Hg, 1 mm Hg=0.133 kPa) and sustained pressure (100 mmHg) serving as the experimental group and the control group, respectively. The experiment was terminated after 4 cycles, and a single cycle included 2 hours of compression and 30 minutes of compression-release. Blood velocity of hind l imbs and blood perfusion of wound were detected by bidirectional doppler blood flow detector and laser doppler perfusion imaging detection system before compression and at every 10 minutes in compression-release period of each cycle (0, 10, 20 and 30 minutes). After the termination, gross observation of the wound was conducted, pathomorphological changes of tissues from compressed area were observed by HE staining, and contents of NO, malondialdehyde (MDA), and superoxide dismutase (SOD) in muscle tissue were measured using colorimetry method. Results No significant difference was evident between two groups in terms of blood flow velocity before compression (P gt; 0.05); the blood flow velocity of two groups decreased significantly at 0 minute in every compressionrelease period of each cycle, and no significant differences were noted between two groups (P gt; 0.05); the blood flow velocity of theexperimental group was higher than that of the control group at 10, 20 and 30 minutes (P lt; 0.05). No significant difference was noted between two groups in terms of wound blood perfusion before compression (P gt; 0.05); the wound blood perfusion of two groups decreased significantly at 0 minute in every compression-release period of each cycle, and no significant differences were noted between two groups (P gt; 0.05); the difference between two groups was not significant at 10 minutes in the first cycle (P gt; 0.05), and the experimental group was higher than the control group at 20 and 30 minutes in the first cycle (P lt; 0.05). In the following 3 cycles, the recovery of perfusion in the experimental group was faster than that of the control group (P lt; 0.05). Gross observation showed the experimental group had less effusion than the control group. The experimental group had intact cutaneous appendage, less inflammatory cell infiltration, and no obvious ulcer formation, whereas the control group had obvious skin ulcer, depletion of cutaneous appendage, and more inflammatory cells infiltration. Significant differences were noted between two groups in terms of NO, MDA, and SOD content (P lt; 0.05). Conclusion Gradually changed intermittent pressure can maintain the blood perfusion of tissue, reduce ischemia-reperfusion injury and cell apoptosis, and prevent the formation of pressure ulcer.
In order to improve the epilepsy management and treatment of Hebei province, improve the life quality of epilepsy patients. Hebei Association Against Epilepsy start a multicenter-clinical trial about the diagnosis, medicine treatment and effect of epilepsy through mobile phone APP. The data collected by health management APP shows that the diagnosis rate of epilepsy syndrome has enhanced from 21% to 39% within six months; also 80.4% of patients have got seizure-free within the first month of treatment. Therefore, the diagnosis and treatment of epilepsy in Hebei province has been improved. However, only 46% of adult patients have been hospitalized within the first 2 years of seizure onset. Therefore, patients need further education about epilepsy in the future. In this trial, the daily management of patients by doctors has come true through the use of mobile phone APP. Through the mobile phone APP, doctors achieved the real-time supervision of disease progress and adjustment of the treatment. This trial provide evidence for future treatment and daily management of epilepsy patients.
