The notational DSA was first proposed for the application as a managing tool of neuronradiology in the early 70's of 20th centery.Later on,three dimensional image reconstruction(3D DSA) was aquired along with the progressing development of technique and equipment devices.As a rather practical instrument,it has been utilized successfully in the diagnosis and management of head and neck vascular disorders,and abdominal parenchymal diseases during recent years.We comprehensively intoduce the application of rotational DSA for the diagnosis and management in hepatic diseases.

ObjectiveTo observe effects of modulated medium frequency low frequency current hydroelectric bath therapy on sequela of ankle fracture.Methods32 sequela patients of ankle fracture were treated with ZM-C type intellectual faculties intermediate frequency therapeutics instrument. Modulated medium frequency square all wave,the frequency of carry wave was 4 KHz,and the frequency of modulated wave was 100 Hz. The water temperature was 40℃. 30 minutes was a time,12 times was a course. Before and after treatment,results were contrasted themselves.ResultsAfter treatment,32 patients all got satisfactory effects,the shorter of the course,the better of the effect.ConclusionThe modulated medium frequency low frequency current hydroelectric bath therapy is a simple,safe and better effect method for sequela of ankle fracture.

Objective To explore the establishment of peptide mapping database of Candida albicans ,laying the foundation for rapid diagnosis of Candida albicans infection .Methods 96 Candida albicans were collected clinically ,and its DNA was extracted . Polymerase chain reaction(PCR) was used to amplify the ITS1-5 .8S-ITS2 gene fragments and restriction endonucleases were a-dopted to identify them .Surface enhanced laser desorption ionization-time of flight-mass spectrometry(SELDI-TOF-MS) instrument was applied to detect the Candida albicans peptide mapping ,and Ciphergen ProteinChip software was used to collect data automati-cally .The established peptide mapping database was verified by confirmed Candida .Results According to restriction fragment length polymorphism analysis ,96 strains were confirmed as Candida albicans .15 peptide peaks were captured by SELDI-TOF-MS chips .Five peptide peaks of them with stable expression were screened out ,and the similarity analysis software was used to estab-lish peptide mapping database of Candida albicans .More than 95% of similarity was found between peptide mapping of Candida albicans and established database ,while less than 50% was found between peptide mapping of other Candida species and database . Conclusion The establishment of peptide mapping database of Candida albicans provides a theoretical basis for the rapid diagnosis of Candida albicans infection .

Background and purpose:Hypoxia induced the decreased radiosensitivity of tumor cells, which was the cause of tumor radioresistance and relapse and metastasis. During the course, HIF-1a played the most important role in the regulation of hypoxia. However, it’s still unknown about the effect of HIF-1a on the radiosensitivity of hypoxia tumor cells and the relationship with autophagy. This study was to inhibit HIF-1αexpression in hypoxic lung adenocarcinoma cell line A549 with RNA interference (RNAi), and explore its effect on hypoxic cell radiosensitivity and autophagy. Methods: Plasmids pHIF-1α-shRNA and Neg-shRNA (negative control) were constructed and transfected into hypoxic A549 cells, this positive clone was named A549/HIF-1α-shRNA. Clone formation array was applied to calculate the value of D0, SF2, SER. The expression of HIF-1α, LC3, c-parp was detected by Western blot. Results:The SF2 of hypoxic A549 cell was 0.62, which was higher than that of normoxic A549 cell, SER was 1.45. The level of LC3Ⅱincreased significantly and the level of c-parp decreased after the radiation of hypoxic A549 cell. The level of HIF-1a increased in hypoxic A549 cells. The expression of HIF-1αin hypoxic A549 cells was suppressed markedly after transfection of HIF-1α-shRNA;this clone was named A549/HIF-1α-shRNA. The SF2 and SER were significantly lower in A549/HIF-1α-shRNA cells, 0.45 and 0.72 respectively. Under the hypoxic condition and after the inhibition of HIF-1α, the expression of LC3Ⅱ decreased significantly and the expression of c-parp increased. Conclusion:We successfully established a cell model that HIF-1αexpression was suppressed almost completely by RNAi. The inhibition of HIF-1αby shRNA may raise the radiosensitivity and decrease the autophagy of hypoxic A549 cells in vitro.

Delightful achievements have been obtained in forestry genetic breeding since the application of transgenic technology in this field during the past 20 years. Field trials of some genetic modified (GM) trees have been carried out, and some GM trees have been commercialized. Meanwhile, the risks of ecological safety caused by GM trees have raised attention in the public gradually. These issues mainly include the horizontal transfer and vertical flow of foreign genes, and the potential effects on insects, soil ecosystems and virus. The current status of field trials, commercial applications and the potential ecological risks of GM trees were summarized. Then the prospects of GM trees were also presented.

Objective To compare and evaluate the effect of PBL in clinical teaching of Pediatrics.Methods Among students of Grade 2002 in our university,two types of PBL,pre-learning and case-discussion,were used in their clinical learning of Pediatrics. And then,their effects were evaluated and compared with those of traditional learning method.Results More than 60% of the students agreed with PBL methods,and they considered PBL favorable to practice scientific logical thinking of clinical affairs,to increase their capabilities of learning,oral expression,communication and cooperation.The teachers agreed with PBL methods too for the better learning effect resulting from PBL.Conclusion PBL fits the needs of medical learning reformation.To train new type of doctors in century 21st,it is necessary to use kinds of new learning methods,including PBL methods and standardized patient (SP)in clinical teaching.
