von Willebrand factor (vWF) and factor Ⅷ (FⅧ) exist in a complex form in blood.After being activated,they mediated platelet adhesion and aggregation,and play an important role in the course of thrombosis.The levels in blood of both of them were affected by a variety of factors.vWF and FⅧ are closely associated with the risk,etiological type,severity and outcome of acute ischemic stroke.Studies on the corresponding antagonistic drugs have made a breakthrough,and these drugs may become more advantageous antithrombotic s.

Stroke-associated pneumonia (SAP) refers to the stroke patients suffering from infectious lung parenchyma (including the alveolar wall,i.e.the general pulmonary interstitial) inflammation without previous pulmonary infection.It is one of the most common major complications resulting in death and affecting functional recovery in patients with stroke.Dysphagia resulting in aspiration is the main reason of SAP.Therefore,avoiding aspiration and preventing SAP have important significance for patients with stroke through early correct tube feeding.This article reviews the tube feeding methods of preventing SAP.

Objective To evaluate the value of dual Doppler ultrasonography in the diagnosis of fetal atrial extrasystoles.Methods Seven thousands and thirteen fetuses were examined by fetal echocardiography.If fetal arrhythmias were found,information of pulsed wave Doppler signals in hepatic vein (HV) and descending aorta (DAo) using dual Doppler were colleted simultaneously.The detected times were compared between using general Doppler and dual Doppler in 20 cases.Results On dual Doppler examination,28 of the fetuses showed signals of atrial extrasystoles,14 fetuses atrial extrasystoles conducted to ventricle,8 fetuses atrial extrasystoles non-conducted to ventricle,6 fetuses with part of the extrasystoles conducted to ventricle and part of the extrasystoles non-conducted to ventricle.No case had congenital heart disease.Twenty-six fetuses with atrial extrasystole were converted to normal rhythm within the third trimester of pregnancy,and the others' were converted to normal rhythm during the first 3 days postnatally.The detected time of dual Doppler was shorter than that of general Doppler(P ＜0.05).Conclusions Dual Doppler ultrasonography of simultaneous recordings in HV and DAo is an easy,rapid method of assessing fetal atrial extrasystoles,which should allow precise diagnosis of atrial extrasystole.

Objective To explore the clinical value of application research in business process reengineering in transferring of inpatients for check-up. Methods We reorganized transferring of inpatients for check-up and service tache by introducing the Systematic Redesign method from the therory of Business Process Reengineering. The reengineered process was adopted and applied in the transferring processes. We randomly selected patients for check-up(126 cases for electrocardiogram,130 cases for Xrayand 128 cases for CT examination)and investigated the time cost for check-up and patients satisfaction rate. The above results were compared with those patients(112 cases for electrocardiogram,112 cases for Xrayand 120 cases for CT examination)before use of reengineered process. Results The time cost for the above mentioned check-up was shorter and patients satisfaction rate were alleviated compared with those before use of reengineered process(U=14.55,12.26,13.57;x2=17.37,14.65,10.75,P＜0.01).Conclusion Application of business process reengineering in the transferring process of inpatients for check-up proved pivotal important in that it could shorten time cost for transferring process and improve patients satisfaction rate.It possessed realistic significance for increasing benefit and competitions for hospitals.

Objective To investigate the expression of hypoxia - inducible factor -1 alpha and vascular endothelial growth factor in gastric carcinoma and its clinical significance. Methods The expression was detected by immunohistochemistry method in 100 cases of gastric carcinoma tissues of patients with carcinoma and HIF-1 alpha, VEGF, VEGF test results comparing the carcinoma tissue and adjacent normal tissues, HIF-1 alpha; different differentiation degree and infiltration depth of tumor tissue of HIF-1 alpha and VEGF detection results of recurrence or metastasis;group, no recurrence or metastasis detection results of HIF-1 alpha and VEGF tumor tissue cancer group. Results The positive rate of HIF-1 expression in gastric tumor tissue of patients with cancer (60.00％), the positive expression rate of VEGF (64.00％) were significantly higher than those in adjacent normal tissues (21.00％, 14.00％), the difference was statistically significant (P<0.05); high ang middle differentiation, invasive depth of tumor tissue before plasma membrane positive in patients with gastric cancer the rate of VEGF, HIF-1 alpha, was low, the data had significant differences (P<0.05); the positive rate of HIF-1 alpha and VEGF expression of gastric carcinoma tumor recurrence or metastasis was found in (70.97％), the positive expression rate of VEGF (77.42％) were significantly higher than those of HIF-1 alpha and VEGF expression in patients with gastric cancer recurrence or tumor tissue the transfer of (55.07％, 57.97％), the difference was statistically significant (P<0.05). Conclusion HIF-1 alpha and VEGF play an important role in the recurrence and metastasis of gastric cancer, is an important basis for the diagnosis and prognosis of gastric cancer patients, clinicians should understand the patients with gastric cancer HIF-1 alpha and VEGF expression, so as to reduce the recurrence and metastasis rate is of important value.

Objective To compare the value of biphasicmulti-detector row helical computed tomogrpahy(MDCT),digital subtraction angiography(DSA)and lipiodol computed tomography(CT)in hypervascular hepatocellular carcinoma(HCC).Methods 80 cases with liver cancer were underwent MDCT、DSA、iodized oil CT scan,then compared detection rates of three methods.Results In detecting hepatic nodules(＞2cm),these three imaging techniques had the same sensitivity;for 1～2cm hepatic nodules,the detecting rate had no significant difference;The MDCT scan＜1cm detected 47 nodules(94.0%),iodized oil CT detected 27 nodules(54.0%),both statistically significant difference in detection rate(χ~2=3.11,P＜0.01),DSA is only detected 16 nodules(32.0%)compared with enhanced dual-phase MDCT scan and iodized oil CT detection rate the differences were statistically significant(χ~2=9.09,9.03,all P＜0.01).Conclusion MDCT is able to better show feeding arteries of hepatocellular carcinoma,The imaging examination of liver cancer before treatment can be used as a comprehensive evaluation.

Objective To compare the value of ultrasound International Ovarian of Tumor Analysis (IOTA) simple rules and gynecologic imaging reporting and data system (GI-RADS) ultrasonographie stratification in the diagnosis of adnexal masses.Methods A total of 463 patients with adnexal masses were classified according to IOTA simple rules by senior doctor.The benign and malignant masses were enrolled in the study.Then the masses were judged according to GI-RADS classification and IOTA simple rules by senior and junior doctors.And junior doctorn in diagnosis of adnexal masses with IOTA was group A1,senior doctor in diagnosis of adnexal masses with IOTA was group B1,junior doctor in diagnosis of adnexal masses with GI-RADS was A2,senior doctor in diagnosis of adnexal masses with GI-RADS was B2.The efficacy of the two methods were compared.Results Among the 463 cases,there were 411 cases (411/463,88.77％) of benign mass and malignant mass by IOTA and 52 cases (52/463,11.23 ％) of uncertain mass.The specificity,positive predictive value,diagnostic accuracy had statistical differences between groups A2 and B2,A1 and A2 (all P＜0.05),and sensitivity and negative predictive value had no statistical differences (all P＞0.05).Diagnostic efficacy index had no statistial signifi cance between group A1 and B1,B1 and B2 (all P＞0.05).Conclusion The diagnostic efficacy of IOTA simple rules and GI-RADS is high and similar in diagnosis of benign and malignant adnexal masse.IOTA simple rules do not depend on experience,but they are not suitable for the diagnosis of all adnexal masses.
