Objective To observe the clinical curative effect of Bushen Tiaochong method on treating early unexplained recurrent spontaneous abortion (URSA). Methods 200 patients who conformed to the inclusion criteria were randomly and paralleled control study divided into two groups.The control group (routine tocolysis group,n =100 ),with 8 cases fell off. The experimental group (routine tocolysis group +traditional Chinese medicine group,n =100 ),with 10 cases fell off. Results After the treatment,the total efficiency of the control group was 70.65%,and the experimental group was 88.89%. The total efficiency of comparative difference was statistically significant (p<0.05 ). And compared the experimental group with the control group,the former group improved the level of human chorionic gonadotropin(HCG)in patients. Conclusion Bushen Tiaochong method with traditional Chinese medicine combined western medicine treatment can significantly improve the symptoms of URSA patients with threatened abortion. Compared with simple western medicine therapy,the former group has better curative effect on early unexplained recurrent spontaneous abortion.

Objective: To analyze the clinical value of 16-slice CT angiography techniques in cerebral artery lesions. Methods:Forty three cases in our hospital with suspected cerebrovascular disease who performed computed tomography angiography were retrospectively analyzed. Volumetric imaging, maximum intensity projection and multi-planar reconstruction technique for three-dimensional reconstruction process were used in post-processing. Results:There were 27 cases with no abnormal blood vessels, 6 cases with aneurysm, 1 with arteriovenous malformation, 8 with arterial stenosis and 1 with congenital abnormalities. The image quality analysis of cerebral vascular trunk and main branches was 100%performed in 43 cases. The location, shape, size, and the relationship with the surrounding blood vessels and skull of the aneurysm have been clearly shown, and the nidus, feeding arteries and draining veins have also been clearly shown. Conclusion:With the features of safe, fast, non-invasive and clarity in images, 16-slice CT angiography imaging technology can be used as the first choice of screening cerebral arterial disease.

Improving medical students' legal quality is not only the requirements of modern education and their self-improvement,but also the needs of reform on medical system in the new era and establishment of a harmonious relationship between doctors and patients.Medical universities should carefully integrate the existing law education resources and establish three staged teaching model (stages of basis law education,health law education and stage of comprehensive improvement) when being fronted with the education model which is unilateral,sporadic and lack of cohesion in order to improve the law quality of medical students.

EEGs performed for new-onset seizures show epileptiform discharge in approximately 18% to 56% of children and 12%to 50%of adults. EEG is the most commonly used means of neurological examination for epilepsy. Speciifc EEG abnormalities help characterize the seizure type and epilepsy syndrome, which allows more informed decisions regarding therapy and more accurate prediction of seizure control and ultimate remission. In certain cases, the EEG may detect more subtle seizures, including absence, myoclonic or partial seizures. In the therapy of epilepsy, the effect of different antiepileptic drugs on the inhibition of epileptiform discharges is different. Epileptiform discharges play a very important role in the prediction of recurrence and the decision to remove antiepileptic drugs.

Objective To investigate the induced expression of indoleamine 2,3-dioxygenase in epithelial cells of cultured human proximal renal tubule under the stimulation of interferon-?(IFN-?)in vitro.Methods The expression of IDOmRNA in epithelial cells of human proximal renal tubule under normal and different dosage or time of IFN-? stimulation were assayed by semi-quantitative RT-PCR,the expression of IDO protein under normal and 2000U/ml IFN-? stimulation for 24h were assayed by immunocytochemistry,and the activity of IDO under different dosage of IFN-? stimulation was assessed by the special kynurenine metabolizable ratio in culture medium detected by high performance liquid chromatography(HPLC).Results No expression of IDO mRNA or IDO was found in the epithelial cells of human proximal renal tubule under normal culture conditions.IDO mRNA expression increased significantly after IFN-? stimulation in a dose dependent manner compared with that of control group(P

In order to have a better understanding of the species diversity of medical plants in Enshi, Hubei of China, extensive field investigations and specimen collections were conducted in Enshi and adjacent regions. Based on field observations of plants in their living habitats and comparative morphological studies on specimens in herbarium of Hubei minzu University and other available herbaria as well, three new records of medical plants in Hubei, Scutellaria yunnanensis, Alangium faberi var. heterophyllum, and Drymaria diandra, were reported in this paper.

Objective To evaluate if the assay of platelet-associated immunoglobulin G (PAIgG) can improve the sensitivity of monoclonal antibody immobilization of platelet antigens assay (MAIPA) in immune thrombocytopenic purpura (ITP).Methods Anti-GP Ⅱb/Ⅲa and anti-GP Ⅰb/Ⅸ autoantibodies were detected by a modified MAIPA;PAIgG was detected by competitive ELISA.MAIPA and PAIgG were done simultaneously in 190 patients with thrombocytopenia,in which 132 were diagnosed as ITP according to the diagnostic criteria Kappa test was used to analyze the concordance between MAIPA and PAIgG.Results The sensitivities of PAIgG alone or in parallel with MAIPA to ITP were 32.6% and 37.2% higher than MAIPA alone respectively,while their specifieities were 51.7% and 56.9% lower respectively.The sensitivity,specificity,positive predictive value,negative predictive value of PAIgG in series with MAIPA were all not superior to MAIPA alone.The kappa values between MAIPA and PAIgG in ITP and non-immune thrombocytopenia were 0.129 and 0.012 respectively,which meant the concordance between them was poor.Conclusion The detection of PAIgG should not be used as screening before MAIPA in distinguishing immune from non-immune thrombocytopenia.

P2X7 is the most important subtype of the ATP receptors known so far. Recent investigations showed that the downstream signaling pathway of P2X7 is coupled with several key inflammatory molecules including IL-1beta and IL-18, this suggests P2X7 might have roles in the inflammatory diseases. Moreover, attenuation of P2X7 by selective antagonists in vitro and knockout mice in vivo reducing the inflammatory response indicated that P2X7 is a potential therapeutic target for inflammatory diseases. However, most previous studies on P2X7 were focused on nerve system diseases most, while its effects in inflammatory respiratory diseases, especially in asthma, chronic obstructive pulmonary disease (COPD) and lung cancer have been poorly investigated. In this paper, we reviewed the research progress on the structure, distribution, biological activities of P2X7 and its relationship with inflammatory respiratory diseases including asthma, COPD and lung cancer, along with the development of P2X7 antagonist as therapeutics.
