Objective To find the different plasma-associated proteins of rheumatoid arthritis (RA) by using two-dimensional gel electrophoresis for understanding the pathogenesis of RA. Methods The total protein from either RA patients or normal ones was prepared by means of immobilized pH gradient based on two-dimensional gel electrophoresis. After silver staining, gel-image analysis was performed by using PDQuest. The differentially expressed proteins were identified by matrix-assisted laser desorption ionization-time-of-flight mass spectrometry (MALDI-TOF-MS). Results 2-DE patterns of plasma from controls and RA patients were presented. The results showed that average number of protein spots was 592 and 563 respectively, and the corresponding average matching rate was 89% and 87% respectively. Gel-image analysis revealed that there were 24 differential protein spots. A total of 15 differential protein spots were successfully identified by MALDI-TOF-MS, of which 6 proteins were up-regulated as compared with control. Conclusion The differentially expressed proteins can be observed in plasma from RA and controls, which can be used to elucidate the pathogenesis of RA for further study.

The Monascus mutant with high yield of yellow pigment was obtained by using conventional relevant mutation techniques, e.g., treating with physical mutagens(such as UV light) and chemical sub- stances (such as N-methyl-N'-nitro-N-nitrosoguanidine). The yellow pigment was scanned from 300 nm to 600 nm with UV spectrometer, the maximal absorption was determined at 410 nm. The growth characteristic of Monascus mutant is stable, the yellow pigment value and colour hue in liquid fermentation can reach 100 U/mL and 3.5 respectively. The yellow pigment is stable from pH 3 to pH 8, but the precipitation appeared as the pH of the pigment solution lower than 3.

Extraction is the critical link during pharmaceutical process of traditional Chinese medicine (TCM), which is directly related to the quality of drugs. So the key to technology upgrading of pharmaceutical equipment in Chinese materia medica enterprise is the development of new extraction techniques, which concerns the modernization of TCM. In this paper, fundamentals, traits, and development status of new extraction technologies were firstly introduced, including ultrasound extraction, microwave extraction, super fluid extraction, semi-bionic extraction method, enzymatic treatment extraction, continuous countercurrent extraction, vacuum extraction. Then information of projects supported by the National Natural Science Foundation of China was analyzed in order to recognize the assistance and research results of new extraction techniques. The patents authorized by the State Intellectual Property Office were also summarized for the purpose of understanding the achievement transformation. The information about extraction equipments was collected and screened to acquire the characteristics and market situation. The results showed that there are still problems about new extraction technologies, such as weak basic study, hard transformation of achievements, and the disconnection between research study and practical application. It is necessary to discuss the approaches and methods for accelerating the transformation of fundamental research, which will provide references for the long-term development of new extraction techniques of TCM.

Objective To present our single-center experience in treating traumatic direct carotidcavemous fistulas (TDCCFs)by using detachable balloon,coil and Willis covered stent via arterial route.Methods During the last five years,transarterial endovascular treatment by using detachable balloon,coil and Willis covered stent was performed in fifty-one consecutive patients of traumatic direct carotid-cavernous fistulas.with a total of 54 TDCCFs.The detachable balloon was the material of first choice,while Willis covered stents and coils were regarded as the back-up materials.A clinical and angiographic follow-up for 348 months (mean 20.8 months) was conducted to evaluate the arterial patency and the stability of embolization.The clinical data were retrospectively analyzed.Results By using the detachable balloon alone via transarterial route.85%TDCCFs were successfully treated with good preservation of ICA.A total of 98% TDCCFs in this study were successfully treated by using detachable balloon,coil and/or Willis coveted stent,the fistulas became occluded,and ICAs were preserved except one patient.Forty TDCCFs were treated with detachable balloons alone,two TDCCFs with the Willis covered stent alone,and one DCCF with coils alone.Eight TDCCFs were treated with detachable balloons together with Willis covered stent.Of these eight TDCCFs,two were treated with a single session,three were treated with detachable halloons in combination with coils,and one had to receive Willis covered stent.Second and third times of endovascular treatment were needed in 12 TDCCFs.The TDCCF-rel(at)ed symptoms were gradually relived or improved within 1 day to 6 months after treatment,except for five patients who suffered from ipsilateral moderate visual loss or cranial nerve deficit.No perioperative complications.such as vessel rupture,distal embolization or new neurologic deficits,occurred.During the follow-up period lasting for six months,neither delayed neurologic or vascular complications nor recurrence of the lesions developed.Conclusion Via the transarterial route,using detachable balloon to occlude the fistula and at the same time to preserve ICA remains the optimal treatment for TDCCFs.When the standard treatment fails.various coils and the Willis covered stents can be used as an effective alternative or remedial tool in the treatment of TDCCFs,which can preserve ICA.Willis covered stent deployment seems to be an effective,safe,feasible and economical endovasculal treatment for TDCCF,but more clinical studies are needed before we can further clarify its specifications and indications.
