Objective To investigate the antithrombotic effects of polydatin.Methods Injection of arachidonic acid into mouse,electrically stimulated carotid artery and inferior vein ligation in rats were used to evaluate polydatins antithrombotic effects respectively.Results Polydatin presented obvious antithrombotic effects in three thrombotic models and showed a good dose-effect relationship.Conclusion It is suggested that polydatin has evident antithrombotic effects in artery,vein and micro-circulation.

Chronic myeloid leukemia (CML) is a malignant clonal proliferative disease,which originates from multifunctional hematopoietic stem cells of bone marrow.Imatinib is used as the first-line treatment for CML currently,owing to its obvious curative effect for patients in chronic phase and survival time prolonged significantly for patients in accelerated phase and blast crisis.With the long-term application of imatinib in clinic,the drug resistance and intolerance gradually appear,resulting in decreased long-term effects of CML.This paper will review the current status of the pathogenesis and treatment of CML.

Heart failure is a serious and terminal stage of various cardiovascular diseases,is one of the most important heart diseases,and it also the most common reason for hospitalization.In recent years,studies on new markers in the diagnosis,treatment and prognosis of heart failure have made great progress,such as B-type brain natriuretic peptide can partially reflect hemodynamic imbalance,troponin can indicate cardiomyocyte injury,soluble ST2 and galectin-3 indicate myocardium remodeling and fibrosis,C-reactive protein,cystatin C and procalcitonin,and copeptin have significant prognostic value for outcomes,microRNA in the regulation of gene expression influence heart failure.

OBJECTIVE To investigate the risk factors of hospital infection among parturients to put forward prevention measures.METHODS The infection cases among parturients in our hospital 2005-2007 were analyzed by retrospective survey.RESULTS The first three infections sites were upper respiratory tract(29.79%);surgical incision(28.72%) and urinary tract(21.28%).The main factor for upper respiratory tract infetion was the traditional postnatal recovering modality.Surgical incision infections were mainly perineum ones.Catheterization after the caesarean operation led to urinary tract infection.CONCLUSIONS Postnatal recovery by scientific modality,aseptic operation and strict infection management are the keys to preventing obstetrical infections.

This article analyzed today's condition of medical bilingual education in our country,considering that the problems lie in the uneven levels of teaching and the deficiency of the environment for language learning and practicing.It put forward a device to set up graded goals and syllabus for bilingual medical education and some methods to create the environment of medical English learning and practicing.

With the efforts of several generations, modern medicine has been from experience medicine and evidence-based medicine to the precise medicine. The precision medicine has also become a common goal for global clinical workers. However, traumatic brain injury involves a wide range and various types of injuries. The extent of the brain damage caused by trauma is complex. There is still a big gap between current medicine and precise medicine in the treatment of traumatic brain injury. Therefore, to achieve accurate, punctual, sharing and individualized precision medicine of traumatic brain injury, we must follow the objective routines of traumatic brain injury, and constantly improve the monitoring and treatment means of traumatic brain injury, and constantly improve the clinical research with globalization, multi-center, large data and prospection.

Objective To evaluate the outcomes of microdiscectomy for treatment of recurrent lumbar disc hemiations. Methods There were 18 cases of recurrent lumbar disc berniations accepted microdiscectomy (reoperation group), compared with 30 cases of primary lumbar microdiscectomy (primary group). Operating time, blood loss and length of hospital stay were compared between two groups. MacNab criteria were used to evaluate the outcomes. Results Operating time was a mean of 75 min in reoperation group, 52 min in primary group. Blood loss of reoperation group was 70 ml, 50ml in primary group. Length of hospital stay was 8.5d in reoperation group, 6.5d in primary group. There were one dural tear, two Ls root lesions and 5 more numbness reoperation group, but recovery all patients. There were one dural tear in primary group. 17 cases got follow-up mean 12.1 months in reoperation group and 29 cases in primary group mean 11.8 months. The results demonstrated 88.2% success rate in reoperation group and 93.1% in primary group. There was no significant dif-ference in two groups (P ＞ 0.05). Conclusion Outcomes of Lambar mierodisceetomy with mini-open for treatment of recurrent lumbar disc herniations are similar to primary lumbar mierodiscectomy.

The possible relationship of vesicular glutamate transporters ( VGluT1 and VGluT2 ) - and 5-HT-like immunoreactive (LI) terminals with mesencephalic trigeminal nucleus (Vme) neurons in the rat was examined by using triple-immunofluorescence histochemistry and double-labeled electron microscopic immunohistochemistry. Under confocal laser-scanning microscope, many neuronal cell bodies of Vme showed phosphate-activated glutaminase (PAG) -LI and the vast majority of them were large pseudounipolar neurons. A considerable number of VGluT1 -LI and VGluT2-LI terminals were widely distributed in Vme, the density of VGluT2-LI terminals was higher than that of VGluT1-LI. 5-HT-LI axonal varicosities had dense distribution in Vme, and some 5-HT-LI terminals also showed immunoreactivity for VGluT2. Some VGluT1-LI, VGluT2-LI, 5-HT-LI and VGluT2/5-HT-LI terminals were frequently observed in close apposition to the cell bodies of Vme neurons showing PAG-LI. Under electron microscope, VGluT1/VGluT2-LI and 5-HT-LI were visualized with silver grains and peroxidase products, respectively. Some terminals in Vme showed both VGluT2- and 5-HT-LI, these dual labeled varicosities usually made asymmetric contact with Vme neurons. Synaptic terminals that showed VGluT1-LI was also observed, but no coexpression of VGluT1 and 5-HT was found in Vme. The present results suggest that in the transmission of the proprioceptive sensory information from the orofacial regions to the higher center, glutamate and 5-HT may play important roles on the regulation of Vme neurons through complicated integration.

Objective To investigate the cause,prevention and treatment of bile leakage. MethodsThe clinical data of 22 cases with bile leakage treated from Jan.1993 to Dec.1998 were reviewed retrospectively. Results Of the 19 cases treated with nonoperative therapy,1 patient died,3 patients were transferred to be operated later, and the other 15 cases were cured. The cure rate of nonoperation was 79%(15/19). 3 patients were cured with emergent operation at the beginning of bile leakage. Of the 3 cases who were transferred to be operated later,2 cases were finally cured by operation while the other 1 patient was not cured.The total cure rate was 91%(20/22). ConclusionBile leakage often oocurs in cholecystectomy procedure and after removal of a T tube, which is mainly related to inflammation, adhesion, abnormality of anatomy and incorrect manipulation. In order to prevent it,surgeons should pay more attention to the 3 links of prirnary procedure, including preoperative preparation,operative management and postoperative treatment. Different treatments are optional according to the degree of leakage and the condition of patients.
