BACKGROUND: It is of great significance to understand the effects of different components of blood pressure on the occurrence of cerebrovascular diseases and administer proper decompression treatments in various situations.OBJECTIVE: To study the relationship of increased pulse pressure with the occurrence and severity degree of cerebral infarction by analyzing the data of pulse pressure recorded in hospitalized patients with acute cerebral infarction.DESIGN: Case-control analysis.SETTING: First Affiliated Hospital of Harbin Medical University.PARTICIPANTS: A total of 300 patients hospitalized at the First Affiliated Hospital of Harbin Medical University between June 2002 and January 2003 for ischemic cerebral infarction were enrolled, including 196males and 104 females aged (57.9±11.9) years. Another 199 persons who came to the same hospital for physical examination at the same period were set as normal group, including 110 males and 89 females aged (55.9±12.4)years.METHODS: ① Measurement of blood pressure: Systolic pressure and diastolic pressure of each person were recorded with mercury sphygmomanometer at the site of brachial artery of the right upper extremity and pulse pressure was calculated. ② Evaluation of neurological impairment:Upon hospital admission, each patient with ischemic cerebral infarction was evaluated with the stroke scale made by the National Institute of Health (NIHSS), in which a higher score means more severe infarction.MAIN OUTCOME MEASURES: ① Comparison of blood pressure parameters of subjects in the two groups. ② Distribution of different pulse pressure levels in the two groups. ③ Comparison of pulse pressure of subjects of different age in the two groups. ④ Results of non-parameters tests of neural function loss in cerebral infarction patients with different pulse pressure levels.RESULTS: ① Mean systolic pressure: It was significantly higher in the case group than in control group [(152±22), (133±19) mm Hg, t' =10.494,P ＜ 0.01]. Mean diastolic pressure: It was higher in the case group than in control group [(93±14), (81±11) mm Hg, t' = 10.129, P ＜ 0.01]. Meanpulse pressure: It was higher in the case group than in control group [(59.61±11.86), (51.93±14.10) mm Hg, t' =5.612, P ＜ 0.05]. Pairwise corre lation analysis showed that Pearson correlation coefficient between pulse pressure and systolic pressure was 0.789 (P ＜ 0.01); Pearson correlation.coefficient between pulse pressure and diastolic pressure was 0.169 (P ＜ 0.01). Therefore, there was a close correlation between pulse pressure and systolic pressure. ② Pulse pressure was distributed between 60 mm Hg and 69 mm Hg in most subjects in the case group, which accounted for 27.7%.It was 40-49 mm Hg in control group, which accounted for 35.7%. It indicated that the incidence rate was high when the pulse pressure was over 60 mm Hg in cerebral infarction. ③ Pulse pressure increased with age.The level of pulse pressure in 40-69 years case group was higher than that in 40-69 control group [(54±16), (45±9)mm Hg, t=4.86, P=0.000]. ④ Patients with cerebral infarction of different levels of pulse pressure were given non-parameter tests of neurological impairment evaluation. The resuits of Kruskal-Wallis test were χ2=4.779, P=0.572 ＞ 0.05; results of median test were as x2=8.365, P=0.213 ＞ 0.05. The results of the two non-parameter tests suggested that there was no significant differences in hospitalization evaluation, that is, although the pulse pressure increased obviously in cerebral infarction, the degree of increase had no correlation with the severity of neurological impairment.CONCLUSION: The increase of pulse pressure is related to the occurrence of cerebral infarction and is also an important factor for evaluating cerebral infarction. However, pulse pressure change is not related to the severity of cerebral infarction.

Objective To predict the prognosis after acute cerebral infarction using a combination of indicators. Methods Two hundred and seventeen patients with acute cerebral infarction admitted from October 2005 to December 2008 were studied. Logistic regression analysis of the data from 112 of the patients admitted from October 2005 to March 2007 was used to select 20 indicators for study. The indicators were combined into prognostic indexes using a multi-layer perception (MLP) neural network (NN) model. Data on the subsequent 105 patients were usedto appraise the model. Results The agreement of the prediction results of the NN model with the real recovery observations was rated as "excellent" in 39 cases, "OK" in 27 and "bad" in 32. The sensitivities were 95.1%,87.1% and 96.9% respectively. On average, the differences between the predicted results with the NN model andthe real recovery were not significant. Conclusion The NN model delivered good precision in predicting the outcome of acute cerebral infarction and it is worthy of further investigation.

Objectives To evaluate the influence of cardio-pulmonary bypass (CPB) to the endothelial function and lipid oxidative status of the Coronary Artery Bypass Grafting (CABG) patients. Methods Thirty-five coronary patients (female 5 cases, male 30 cases, mean age 59.5±8. 6 years) who needed CABG operation therapy were included. The control group consisted of 20 health volunteers (female 5 cases, male 15 cases, mean age 49. 5 ± 7.3 years).Blood samples were taken at preoperative, 3 and 7 days postoperative. Serum von Willebrand factor (vWF) level, one of the endothelial dysfunction markers,and oxidized low density lipid (OxLDL) level, one of the lipid oxidization status markers were detected with ELISA kits. Results The levels of vWF and OxLDL in CABG patients' serum were elevated significantly compared with those of control group ( 139.60% ± 34. 39% vs 82. 79% ±13. 89% and 63. 7 ±18. 9U/ml vs 25.4± 15.2U/ml respectively). Three and 7 days after CABG significant increases in the vWF level (194. 30% ±37. 74%; 181.07% ±31.05%vs 139.60% ±34.39% at baseline, P＜0. 0001, respectively) and OxLDL level (79. 3±26. 7U/ml; 72.4±23.1U/ml vs 63.7±18. 9U/ml at baseline, P＜0. 01, respectively) were detected. Conclusion Compared with normal people, the endothelial system of CABG patients is impaired, and their lipids are in a more oxidative status. CABG procedure with CPB can further deteriorate the conditions, which may imply that the patients are predisposed to acute coronary accident shortly are the procedure.

ObjectiveTo improve the visualization of anteromedial and posterolateral bundles of anterior cruciate ligament (ACL) and investigate the optimal MRI plane for the bundles at a 3.0 T MR scanner.MethodsMR images of 149 knee joints were reviewed retrospectively.Display rates of AMB,PLB and their different parts (the top portion,the middle portion and the low portion) on MR different planes including axial,sagittal and coronal planes were analyzed and their differences were compared with the x2 section method.ResultsThere was no statistical difference in the display rates of two bundles of ACL between axial plane ( 115/149,77.2％ ) and coronal plane (103/149,69.1％ ) (x2 =2.4606,P ＞0.0125 ).Statistical differences were found between axial and sagittal plane,coronal plane and sagittal plane (21/149,14.1％ ) ( x2 =119.5138,92.8695 respectively,P ＜0.0125 ).There was a statistical difference for the top portion of ACL between axial plane ( 104/149,69.8％ ) and coronal plane,sagittal (0/149,0)and coronal planes ( 7/149,4.7％ ) ( x2 =135.081,159.7526 respectively,P ＜ 0.0125 ),between sagittal and coronal planes (x2 =7.1684,P ＜ 0.0125 ).For the middle portion of ACL,there was no statistical difference between axial plane ( 108/149,72.5％ ) and coronal plane (94/149,63.1％ ) (x2 =3.0120,P ＞ 0.0125 ),while statistical differences were found between axial and sagittal plane,coronal planes and sagittal plane ( 10/149,6.7％ ) ( x2 =134.7454,104.2173 respectively,P ＜ 0.0125 ).For the low portion of ACL,there was no statistical difference between axial plane ( 103/149,69.1％ ) and coronal plane (101/149,73.8％ ) (x2 =0.8065,P ＞0.0125),while statistical differences were detected between axial and sagittal plane,coronal planes and sagittal plane ( 18/149,12.1％ ) ( x2 =100.5300,115.9132,P ＜ 0.0125 ). The different parts of ACL displayed low intensity on different MR planes and normal morphology.ConclusionsACL can be displayed on conventional MR planes at a 3.0 T MR scanner to some extent.Axial and coronal planes might be the optimal MRI planes for ACL and its two bundles.

Objective To investigate the association of single nucleotide polymorphisms(SNP)in p21and p27 genes with the risk of epithelial ovarian cancer(EOC).Methods Genotypes were analyzed by polymerase chain reaction-restrictive fragment length polymorphism(PCR-RFLP)method in 234 patients with EOC and 284 control women in China.Results (1)The frequencies of the p21 in healthy controls were 34.2%.49.6%and 16.2%,while the distribution of the C and T allele was 59.0%and 41.0%,respectively.The p21 C/C(28.2%),C/T(53.0%),T/T(18.8%)distribution in ovarian cancer patients was not significantly different from that in healthy controls(P＞0.05).There was no statistic difference in allele distribution between ovarian cancer patients and healthy controls(P＞0.05)either.The stratification analysis by tumor histological type did show that the genotype distribution in four types of ovarian cancer patients was significantly different from that in healthy controls(P=0.02).The C/C genotype was likely to reduce the risk of epithelial endometrial cancer.and the adjusted odds ratio was 0.56(95%CI:0.32-0.98).(2)The genotype frequencies of the p27 in healthy controls were 88.4%,10.9%and 0.7%.while the distribution of the V and G allele was 93.8%and 6.2%.respectively.The V/V(93.6%),V/G(5.1%)and G/G(1.3%)distribution in ovarian cancer patients was significantly different from that in healthy controls(P=0.04).There was no statistic difference in allele distributionbetween ovarian cancer patients and healthy controls(P＞0.05).Compared with the V/G and G/G genotypes,the V/V genotype increased the risk of EOC,the adjusted odds ratio was 1.92(95%CI:1.02-3.63).Conclusion The C/C genotype of p21 may reduce the risk of epithelial endometrial cancer,and the genotype of p27 V/V may be a potential risk factor for susceptibility to EOC.
