Objective To evaluate myocardial coronary flow reserve of syndrom X by real-time myocardial contrast echocardiography(MCE). Methods Ten patients with syndrome X and seven normal subjects were involved in the study. Real-time MCE was performed with acoustic contrast SonoVue,and the peak video density (A), and re-turgor velocity of microvessel (β), and the product of A ×β of quiescent condition and after adenosin loading were detected,and also the coronary flow reserve (CFR, the ratio of A xβ circa-adenosin loading). Results There was no significant difference of A between syndrom X and contrast group in quiescent condition, the β and product of A x β of patients with syndrome X were lower than those of contrast group, the CFR of syndrome X was obviously less than that of contrast group.Conclusions Myocardial microvessel function is abnormal in syndrome X, real-time MCE is useful for evaluate myocardial coronary flow reserve.

Objective To explore the protection of the facial-acoustic nerve during microsurgery for acoustic neuroma via the suboccipital retrosigmoid approach. Methods The clinical data of 25 cases with acoustic neurinoma treated by the suboccipital retrosigmoid approach were retrospectively analyzed. Results Total removal was achieved in 22 patients and subtotal in 3 patients. 20 with Cochlear nerve anatomic preservation at 2 weeks after surgery and 3 patients with effective hearing and 13 patients lost effective hearing but retained measurable hearing and 9 patients completely lost hearing( the New Hannover Classification V grade). The facial nerve was preserved anatomically in 18,H-B Grade I ～ IV in 15,Grade V ～ VI in 10. There were not cerebrospinal fluid leakage, intracranial infection and death in all cases. Conclusion When operating,the relation between the tumor and the important structure surrounding could should be understood fully. Then removed the tumor piece by piece with microsurgical techniques. That the effective way to keep the facial nerve and its function being protected,and could improve the prognosis of the operation.

Objective To study the reasonable treatment to the patients with raptured intracranial aneurysms of hunt-hess Ⅲ-IV grade in the cerebral vasospasm stage. Methods The clinical data of 80 patients with ruptured intracranial aneurysms of hunt-hess Ⅲ-IV grade were analyzed retrospectively. All of the patients were clipped closed by microsurgery (36) or embolized intervention(44) in 3～18 days after disease. According to the time of surgical intervention after disease,they were divided into 42 patients with early(3～10 days) surgical group and 38 patients with advanced(11～18 days) surgical group. The different operative methods and different treatment periods were compared in order to evaluate the effect to the prognosis, the DIND incidence and the ruptured again aneurysms during operation incidence. Results There was no statistical significance in the effect about early or advanced surgical intervention to the prognosis, the DIND incidence and the ruptured again aneurysms during operation incidence (P > 0.05). There was no statistical significance in the effect about advanced interventional embolization or clipping closed by microsurgery to the prognosis,the DIND incidence and the ruptured again aneurysms during operation incidence(P > 0. 05). There was statistical significance in the effect about early interventional embolization or clipping closed by microsurgery to the prognosis,the DIND incidence and the ruptured again aneurysms during operation incidence(P< 0.05). The interventional embolization had better prognosis,more lower DIND incidence and more lower ruptured a-gain aneurysms during operation incidence than the clipping closed by microsurgery. Conclusion The patients with ruptured intracranial aneurysms of hunt-hess Ⅲ-IV grade in the cerebral vasospasm stage should be earlier intervened surgically,then it seems that interventional embolization is more reasonable which is worth referencing in clinic. The good operation habits during operation and the effectively strengthening management after operation had positive significance to ensure operative effect and to improve prognosis.

Objective To study the possible reasons and the processing strategy of brain injury operation complicated with intracranial hemorrhage.Methods The clinical data about 22 patients who were digged skull operation because of brain injury and complicated with intracranial hemorrhage in operation in neurosurgery from 2007 June to 2008 February were retrospectively analyzed,and different types intracranial hemorrhage were classified.Results In 22 patients,12 patients were complicated with epidural hematoma,in which the patients (9/12,75.0%) complicated with opposite hematoma were common;5 patients were complicated with intracerebral hematoma,in which the patients (3/5,60%) complicated with ipsilateral hematoma were common;4 patients were complicated with acute subdural hematoma,and all the patients complicated with opposite hematoma;1 patient was complicated with sub-flap hematoma.Conclusions In the patients who are complicated with intracranial hemorrhage because of digging skull operation to brain injury,epidural hematoma are most,then intracerebral hematoma,subdural hematoma,sub-flap hematoma.The important measures of preventing secondary intracranial hemorrhage are definiting force mechanism and distinguishing fracture line before operation,gradiently decompressing,completely removing crushing brain tissue,protecting reflux veins,rigorously stopping bleeding during operation.

Orthogonal descriptors is a viable method for variable selection, but this method strongly depend on the orthogonalisation ordering of the descriptors. In this paper, we compared the different methods used for order the descriptors. It showed that better results could be achieved with the use of backward elimination ordering. We predieted Rf value of phenol and aniline derivatives by this method, and compared it with classical algorithms such as forward selection, backward elimination, and stepwise procedure. Some interesting hints were obtained.

Colorectal cancer is the third high incidence of tumor in the world,and liver is one of the most common sites of distant metastasis.Liver metastasis accounts for 50％-75％ in distant metastasis.Only about 10％ -15％ of patients are candidates for resection,and the recurrence is easy.Selective internal radiation therapy is a new type of radiotherapy.It is partial and liver-targeted.For unresectable colorectal liver metastasis,selective internal radiation therapy alone or in combination with other therapies can reduce cancer focus,prolong the survival,and maybe improve overall survival.

Objective To study on the efficacy of Octreotide prophylaxis of post ERCP pancreatitis (PEP) and hyperamylasemia. Methods The study was conducted in 12 digestive endoscopic units in China. Patients were randomized into two groups. Octreotide group: Octreotide (0. 3mg) were dissolved in 500 ml of 0.9% saline solution and administrated by continues intravenous infusion, beginning 1 hr before the endoscopic examination and continuing for 6 hr afterward, 0. 1 mg Octreotide were injected subcutaneously at 6h, 12h after the intravenous injection stopped. Control group was given a placebo (saline solution) intravenously without subcutaneous injection. Results A total of 961 patients were accepted in the study, 832 patients were enrolled in the final analysis, Octreotide group 414 cases, and control group 418 cases. The overall incidence of acute pancreatitis was 3.85% (32/832) .which includec 2.42% (10/414) in Octreotide group and 5. 26% (22/418) in control group (P =0. 046). Incidence of hyperamylasemia was 14. 9% (124/ 832) which included 12. 32% (51/414) in Octreotide group and 17. 46% (73/418) in controlled group (P = 0. 041). The two groups were matched in many basic aspects, such as sex, age, contrast agent, indication of ERCP, the times of visualization of pancreatic duct and bile duct, etc. There was no side effect associated with Octreotide found. Conclusion The results of this trial indicate that Octreotide can prevent post ERCP pancreatitis and hyperamylasemia.
