Objectives To investigate the regularity of fluctuation and clinical senses of serum c reactive protein (CRP) level in patients with acute cerebral infarction (ACI) Methods 100 subjects (56 males and 44 females) were divided into five groups including 24 large artery arteriosclerosis (LAA), 27 small artery occlusion (SAO), 2 cardiac embolism(CE), 34 other Certain(OC) and 13 undetermined etiology according to Trial of ORG 10172 in Acute Stroke Treatment (TOAST) Through enzyme linked immunoabsorbent assay (ELISA), we detected and analyzed CRP levels of 100 inpatients Results The risk factors of stroke included coronary heart disease , hypertension, diabetes and intoxication of CO and so on Among the above mentioned, the level of CRP and rate of positive CRP of patients who poisoned by CO was the highest That of coronary heart disease group was lower However, there was no notable difference between hypertension and diabetes groups Conclusions CRP may play a certain role in the occurrence and development of ACI It represents different levels in different types of stroke

In order to investigate the interelationship between copper deficiency and lipidemia, an experiment was done in weanling rats fed normol and copper deficient diet for one month. At the end of experimental period, the growth rate, the contents of copper, zinc, cholesterol and triglyceride in plasma and the activity of monoamine oxidase (MAO) in plasma were measured. The differences between the two diets were compared by student's test and the relation between plasma copper and plasma cholesterol or MAO was ascertained by regression analysis.The results showed that a lower body weight gain and a highly significant hypercholesterolemia were found in copper deficiency rats and the plasma cholesterol concentration correlated reversely with the plasma copper (r = -0.724, p

Objective To study the regulatory effect of ethanol extract of glossy privet fruit and its monomer tyrosol on the adhesion and migration of human epidermal melanocytes.Methods Epidermal melanocytes were isolated from human foreskin,and subjected to a primary culture.Mter 3-5 passages,the melanocytes were treated with various concentrations of ethanol extract of glossy privet fruit (0.0375-0.6 mg/ml)and tyrosol (0.125-2 mmol/L) for 24-72 hours.The XTT colorimetric assay was carried out to evaluate the proliferation of melanocytes,fibronectin (FN)-coated culture plates were used to evaluate the adhesion activity of melanocytes,and Transwell assay was conducted to assess the migration activity of melanocytes.Confocal laser microscopy was utilized to observe the structure and distribution of actin cytoskeleton in melanocytes,and cellular fluorescence intensity was determined by a semi-quantitative analysis.Statistical analysis was carried out by using unpaired t test.Results The adhesion activity of melanocytes to FN was significantly enhanced by the ethanol extract of 0.0375-0.6 mg/ml from glossy privet fruit (P ＜ 0.05 or 0.01),and by tyrosol of 0.5-2 mmol/L (P ＜ 0.05 or 0.01).As XTT assay showed,neither the ethanol extract of 0.15 mg/ml nor tyrosol of 2 mmol/L had cytotoxicity or promotive effect on cell proliferation.Hence,0.15 mg/ml and 2 mmol/L were determined as the working concentrations of ethanol extract and tyrosol respectively.The number of cells migrating through micropore membranes per high-power field (× 200) was 43.7 and 51.0 in melanocytes treated with the ethanol extract of 0.15 mg/ml and tyrosol of 2 mmol/L,respectively,significantly higher than that in untreated melanocytes (20.3,both P ＜ 0.01).Compared with untreated melanocytes,those treated with the ethanol extract of 0.15 mg/ml and those with tyrosol of 2 mmol/L showed higher intracellular fluorescence intensity (P ＜ 0.01) and more stress fiber bundles which congregated inside the cell membrane and around the nuclei.Conclusions The ethanol extract of glossy privet fruit and its monomer tyrosol can promote the adhesion and migration of human melanocytes in vitro,likely by promoting the congregation of actin cytoskeleton in melanocytes.

BACKGROUND: At present, international classification of diseases by WHO, cerebrovascular disease classification used in China and TOAST classification used abroad are all based on patho-physiology. There is no report about human cerebral infarction by magnetic imaging types in Beijing and other areas.OBJECTIVE: To analyze retrospectively the subtype distribution of acute cerebral infarction of patients in Beijing by magnetic resonance imaging in order to make Beijing patients with acute ischemic stroke receive more exact and individualized treatment.DESIGN: Retrospective case study.SETTING: Department of Neurology, General Hospital of Beijing Military Area Command of Chinese PLA.PARTICIPANTS: The study was carried out in General Hospital of Beijing Military Area Command of Chinese PLA, Beijing Sino-Japan Friendship Hospital, Beijing Chaoyang Hospital, Beijing Naval General Hospital and Beijing Jishuitan Hospital between January and December 2004. Totally 602 inpatients with ischemic stroke who received treatment in each hospital were recruited. They were 352 male and 250 female with average age of (65.6±10.2) years.METHODS: The 602 patients with acute ischemic cerebral stroke who received the treatment in the 5 hospitals from Dongcheng, Xicheng,Chaoyang and Haidian districts in Beijing were recruited in the study. According to results of magnetic resonance imaging of brain, the maximal infarction area were determined. The patients were classified as: large infarction: over 1 lobe of brain, ＞ 5.0 cm in diameter; moderate infarction: less than 1 lobe of brain, 3.1-5.0 cm; small infarction: 1.6-3.0 cm; lacunar infarction, ＜ 1.5 cm.MAIN OUTCOME MEASURES: Constitution ratio of MRI classification of patients in each groupRESULTS: Totally 602 patients with ischemic stroke participanted in final result analysis. Among the patients with acute cerebral infarction of 5 hospitals in Beijing, 280 (46.5%) suffered from lacunar infarction, 299(38.1%) from small infarction, 57 (9.4%) from moderate infarction, and 36 (6%) from large infarction. There were significant differences between lacunar infarction and other types (P ＜ 0.01).CONCLUSION: Acute cerebral infarction of patients of Beijing mostly occurs in the type of lacunar infarction. It suggests that small arterial diseases are the major disease type of ischemic stroke in Beijing. This MRI classfication can be used for early classification, treatment guidance, evaluation and prognosis of acute ischemic cerebral stroke.

Objective We conducted a study using MRI and ambulatory blood pressure monitoring(ABPM) to determine whether an inapporpriately low nocturnal blood pressure,or an excess fall in nocturnal blood pressure,might be responsible for lacunar infarct.Method ABPM and Casul blood pressure(CBP) were examined in 35 hypertentives with lacunar infarct( LI） and 33 hypertentives without lacunar infarct as control group.Results There is no significant difference of CBP between two groups.But the mean nighttime systolic blood pressure(nSBP) and diastolic blood pressure(nDBP) in patients with lacunar infarct were significantly smaller than in patients without lacunar infarct.The ratio of nSBP/dSBP and nDBP/dDBP in SI were smaller than in control group respectively.Conclusions The results indicate that an inappropriately low nocturnal blood pressure,or an excessive fall in nocturnal blood pressure,is associated with lacunar infarct.It is necessary not only to controlhigh blood pressure but also to pay attention to circadian changes of blood pressure during the course of anti-hypertensive treatment.

Objective To study the effects of lipopolysaccharide(LPS) on the expression of toll like receptor 4 (TLR4), reactive oxygen species(ROS) and on the proliferation of cells as well as secretion of six proinflammmatory cytokines including TNF-α, IL-1, IL-6, IL-8, IL-10, IL-12 levels in SKOV3 cells. And to explore the mechanism of SKOV3 cells in regulation. Methods Cultured primary SKOV3 cells were stimulated with different concentrations of LPS (0.01 μg/ml, 0.1 μg/ml, 1 μg/ml, 10 μg/ml and 20 μg/ml) for 4 h, the TLR4 expression in SKOV3 cells were examined by flow cytometry;1 μg/ml LPS stimulated SKOV3 for 4 h, 8 h, 12 h, 24 h respectively, the TLR4 expression and cell cycle in SKOV3, cell proliferation, ROS level as well as cells and TNF-α and IL-1, IL-6, IL-8, IL-10, IL-12 levels in the culture medium were assayed by flow cytometry, MTT, CBA assay respectively. Results LPS with different concentrations of LPS stimulation in-duced an increased TLR4 expression, however, the expression was reduced when LPS concentration up to 10 μg/ml. LPS stimulation for 4 h, 8 h induced an increased TLR4 expression and cell proliferation. Stimulated for 24 h, however, the TLR4 expression and cell growth were inhibited in S period. Meanwhile, LPS stimulation for 4 h, 8 h, 12 h, 24 h induced a higher ROS secretion in comparison with control group. LPS stimulation induced a stronger cytokine response in comparison with control group, as demonstrated by the production of TNF-α, IL-1, IL-6, IL-8 secretion in cultured SKOV3 cells, while IL-10 and IL-12 with low expression have no obvious difference in the all medium samples. Conclusion TLR4 expression, cell proliferation, ROS and proin-flammmatory cytokine secretion could be induced in SKOV3 through LPS stimulation. The study provide new ex-periment evidences for human ovarian cells SKOV3 immunity regulation and inflammation reaction to promote cells inhibition after LPS stimulation.

Objective To study clinical features of severe craniocerebral injuries complicated by upper cervical vertebral injuries so as to have a deeper understanding and higher vigilantness. Methods Twenty-nine cases of severe craniocerebral injuries complicated by upper cervical vertebral injuries were clinically analyzed. Results Injury causes included traffic accident in 26 cases, fall in one, rolling down in one and mine collapse in one. Treatment results showed that 16 cases survived and 13 died. As for Glasgow Outcome Scale (GOS) score, two cases were ranked at grade Ⅴ, seven at grade Ⅳ, six at grade Ⅲ, one at grade Ⅱ and 13 at grade Ⅰ. Conclusions The severe craniocerebral injuries complicated by upper cervical vertebral injuries are critical and complex mainly because the severe craniocerebral injuries can be paid more attention and diagnosed and treated early while the upper cervical vertebral injuries are easy to be neglected, as gives rise to missed injuries, lack of timely management and high mortality. Therefore, various severe complications are liable for deaths.
