Extracranial-intracranial arterial bypass, an elegant procedure, was first performed and developed gradually by M. Gazi Yasargil. It has been used in the management of ischemic cerebrovascular disease, moyamoya disease, intracranial aneurysms and brain tumors.This article focuses on its application in the ischemic cerebrovascular disease, and reviews it from the aspects of cerebral hemodynamics of ischemic cerebrovascular disease, indications for arterial bypass, preoperative evaluation, operating modes, intraoperative assessment,complications, postoperative care and prognosis.

OBJECTIVE:To explore the ward round model of clinical pharmacists.METHODS:The ward round model of clinical pharmacists was designed and explored based on clinical practice.RESULTS & CONCLUSION:Clinical pharmacists can engage in ward rounds either in cooperation with physicians or alone in special department,or by targeting at those patients using certain drugs.Each model has its distinctive characteristics and clinical pharmacists can choose suitable model based on their own level as well as the conditions in software,hardware and environment so as to facilitate rational administration.

OBJECTIVE:To discuss the possibility of null stock in hospital drug storehouse.METHODS:The current situation of the drug storehouse of our hospital and pharmaceutical company of our district,and the existing problems in implementation of null stock were analysed.RESULTS & CONCLUSION:There exist difficulties in carrying out complete null stock in hospital drug storehouse now,however,if computer network is adopted and the drug storage is shared by both hospital and pharmaceutical company,implementation of null stock in hospital drug storehouse will be practical.

Objective To explore the correlations between quantitative parameters of dynamic contrast-enhanced MRI ( DCE-MRI) and nasopharyngeal carcinoma ( NPC) clinical stage.Methods 69 patients with NPC were selected from Oct 2013 to Oct 2015 in Shaoxing People's Hospital,39 men and 30 women,aged 39-76 years old,average 50.6 ±10.5 years old.All patients underwent clinical staging,DCE-MRI and histopathological examina-tion before treatment.Clinical stages were determined based on Chinese 2008 staging system.Value of the volume transfer constant ( Ktrans) and the extravascular extracellular space volume per unit volume of tissue ( Ve) was detec-ted by bi-compartmental pharmacokinetic model.The correlations between quantitative parameters and clinical stage were analyzed by Pearson correlation analysis.Results Mean Ktrans and Ve for NPC were (0.532 ±0.156) mL/min/100cm3 and (0.982 ±0.356),respectively.Ktrans of NPC showed negative correlation with clinical stage (r=-0.506,P=0.001),T stage (r=-0.326,P=0.014),N stage (r=-0.296,P=0.017) and M stage (r=-0.312,P=0.015),while Ve showed positive correlation with clinical stage (r=0.415,P=0.002),T stage (r=0.478,P=0.001),N stage (r=0.318,P=0.015) and M stage (r=0.346,P=0.011).Conclusion DCE-MRI quantitative parameters are significantly related to clinical stage of NPC,which has important values for clinical treat-ment and prognostic assessment.

Objective To evaluate the physical dependence of Zhixieling capsule.Methods The physical dependence of Zhixieling capsule was observed by mouse jump test,rat precipitation test and rat natural withdrawal test.Results Zhixieling capsule showed no obvious withdrawal symptoms.Conclusion Zhixieling capsule has no physical dependence.

This paper reports the methods of inducing animal model of abdominal aortic aneurysm(AAA) and the research on etiology.The formation of AAA is the result of cooperation of multifactors such as genetic and biochemistric facfors.Different animal models of AAA can provide a possibility in researching the etiology and pathogenesis of AAA etc, and useful in judging the therapy and prognosis .

OBJECTIVE Epithelial-myoepithelial carcinoma (EMC) is a rare malignant neoplasm of the salivary glands. The aim of the study was to investigate the diagnosis, treatment and prognosis of EMC of the parotid gland.METHODSThe clinical data of 23 cases of EMC of the parotid gland from 1999 to 2013 were analyzed retrospectively. Of all the patients, 13 cases received radical surgery only, 9 cases received postoperative radiotherapy, and one case received postoperative chemotherapy. Kaplan-Meier survival curve was used to analyze the clinical data. RESULTSThe overall survival rate at 5-year was 81.0% and the overall no recurrence survival rate at 5-year was 67.3%. The recurrence rate was 39.1% (9/23). The 5-year no recurrence survival rate of radical surgery group was 55.6%, compared with 80.0% in the combined modality therapy group, there was no significant deference (χ2=2.232, P=0.135).CONCLUSIONThe postoperative recurrence rate of EMC is high. Radical surgery could be the main treatment of EMC, when the surgical margin couldn't be achieved, adjuvant radiotherapy or chemotherapy might be helpful.

Objective To investigate clinical significance of soluble CD30/CD30L and CD40/CD40L system imbalance in ovarian serous tumors.Methods 40 patients of serous cystadenoma and 30 patients of serous cystadenocarcinoma were selected,and 40 age-and weight-matched healthy women were also recruited as the control group.Peripheral venous blood (3 ml) of the healthy control and patients with ovarian serous tumors before surgery and 7 days after surgery were collected.After separation of serum,ELISA was used to detect levels of sCD30,sCD30L,sCD40 and sCD40L.Results Compared to the control group,levels of sCD30,sCD30L,sCD40 and sCD40L in both serous cystadenoma and serous cystadenocarcinoma groups were significantly in creased (P＜0.05).And in those serous cystadenocarcinoma group,levels of such soluble proteins were much higher than in serous cystadenoma group (P＜0.05).7 days after surgery,levels of such soluble proteins were significantly decreased in both serous cystadenoma and serous cystadenocarcinoma groups (P＜0.05).Conclusion Detection of serum sCD30/sCD30L and sCD40/sCD40L is possible to have a certain guiding significance to early diagnosis of ovarian tumors and the prognosis of patients.

Objective To investigate the clinical value of MR diffusion tensor imaging (DTI) in evaluating diffuse axonal injury (DAI).Methods The DTI imaging data of DAI patients and healthy volunteers were analyzed retrospectively.Fractional anisotropy (FA) values were measured in corpus callosum,etc.The serum myelin basic protein (MBP) was detected.Results Compared to the control group,the FA values were lower in genu of corpus callosum,splenium of corpus callosum,anterior limb of the internal capsule,posterior limb of the internal capsule and thalamus in DAI group (P ＜ 0.01,P ＜ 0.05).The mean FA values of two groups were negatively correlated with serum MBP levels (r =-0.755,P =0.001).Conclusions DTI can noninvasively reflect the damages of white matter fibers in DAI patients,and it has importantly clinical significance in evaluating prognosis and therapeutic effect of DAI patients.
