Atherosclerosis is a pathegenesis process involved in the inflammatory and proliferative responses of cells in which endothelial cells have an important function in the regulation of a variety of genes. A variety of molecules have been identified in the atherosclerotic environment that are able to activate NF ?B. Possible functional implications for activated NF ?B in atherogenesis are discussed by protecting endothelial cells selectively, perhaps, it may provide a new method for the therapy of the atherosclerosis.

Traditional Chinese medicine Curcuma Zedoary ( E'Zhu) contains essential oil, curcuminoid and other effective constituents, with such pharmacological actions as anti-platelet aggregation, lowing blood lipid, anti-oxidation and anti-inflammation. In recent years, studies have showed that certain extracts and chemical components of E'Zhu could mitigate myocardial cell mitochondria injury and protect vascular endothelium by enhancing heme oxygenase-1 activity, inhibit nuclear factor NF-kappaB, target genes interleukin-associated kinase-1 (IRAK-1), tumor necrosis factor receptor-6 (TRAF-6) and vascular cell adhesion molecule-1 (VCAM-1), reduce inflammatory infiltration, and inhibit growth factor-induced smooth muscle cells (SMCs) proliferation and migration by impacting oxidation of cellular phosphatases. Due to its different functions in vascular endothelial cells and smooth muscle cells, E'Zhu has been applied in drug-eluting stents, with a potential effect in preventing in-stent restenosis and thrombogenesis. In this paper, studies on pharmacological effects and mechanisms of extracts and main chemical constituents from E'Zhu in preventing vascular restenosis were summarized.

The systematic position of Fritillaria hupehensis has been in dispute. Phylogentic analyses were conducted on sequences of ITS, rpl16, matK sequences for species of F. hupehensis and allies. Lilium davidii was designed as outgroup. The analyses were performed using MP and ML methods. Conclusions could be achieved as follow. The topologies of MP and ML are consistent. The samples of F. hepehensis from different places form a supported clade with a strong bootstrap. And then form a strongly supported clade with F. anhuiensis, F. monantha. The results suggests that although F. hupehensis has a closet relation with the two ones, it exists some difference.

OBJECTIVETo introduce a better surgical approach for the resection of tumors involving the anterior and middle skull base and the fronto-orbito-ethmoidal area.
METHODSA "T" form incision was made in the fronto-orbito-ethmoidal region and along the nasal pyramid down. Parts of ethmoid sinus, lamina papyracea, fronto-orbito bone and behind wall of frontal sinus were resected in order to expose the tumors in the anterior skull base and the fronto-orbito-ethmoidal region. Then, the tumor was resected partly under the operation microscope, protecting the neighbouring important structures, for instance: optic nerve, internal carotid artery, sella, meninx, etc. The nasal pyramid was repaired and fixed to the frontal bone with titanium board and titanium nail in order to resume the appearance of a good face.
RESULTSThirteen patients received tumour resection through this approach. The patients were followed-up for 24 months, 11 patients showed no tumour recurrence, no severe complication, such as cerebrospinal rhinorrhea, meningoencephlocele, etc, in this series. The facial appearance was good.
CONCLUSIONSThe approach via the fronto-orbito-ethmoidal region is a good surgical procedure to resect the tumors involving the anterior and middle skull base and the fronto-orbito-ethmoidal area.

OBJECTIVETo study modified ilioinguinal approach through the retrospective analysis on the surgical treatment of 63 patients with pelvic and acetabular fractures through anterior approach.
METHODSFrom January 2006 to January 2013, 63 patients with pelvic and acetabular fractures were treated with the ilioinguinal anterior approach, including 45 males and 18 females, ranging in age from 12 to 68 years old, with an average of (37.71 +/- 13.41) years old. All the patients were divided into two groups: standard ilioinguinal anterior approach group (group A) and modified ilioinguinal anterior approach group(group B). In group A, there were 26 males and 11 females, with an average age of (38.49 +/- 13.64) years old. In group B, there were 19 males and 7 females, with an average age of (36.62 +/- 13.29) years old. Intraoperative and postoperative indicators in group A and B were observed and compared, including operation incision exposure time (from skin incision to complete the ilioinguinal in front of three "windows"), the blood loss, incision close time and treatment effect of Majeed function score.
RESULTSCompared to group A, the incision exposure time of patients in group B was shorter, the blood loss (bleeding during exposure process) was less, and the close incision time was shorter, but the treatment effect of Majeed function score had no significant differences between two groups. All the patients were followed up, and the during ranged from 3 to 36 months, with an average of (18.6 +/- 9.2) months. According to Matta standard assessment reduction of pelvic and acetabular fracture, there were 28 patients got an excellent result, 8 good, and 1 fair in the group A; and 20 patients got an excellent result, 5 good, and 1 fair in the group B. According to Majeed function score for hip function, 20 patients got a satisfactory result, 12 good,4 fair and 1 poor in group A, and the mean score was 82.51 +/- 9.72; and 13 patients got an satisfactory result, 10 good, 3 fair and 0 poor in group B, and the mean score was 80.54 +/- 10.79.
CONCLUSIONThe modified approach has several advantages as follows: providing a good surgical exposure; preventing from the injury of femoral nerve, femoral artery and vein under the inguinal ligament; not needing to open the inguinal canal, which can avoid the occurrence of inguinal hernia, reduce operation prodedures and shorten operation time.

The quality of Chinese medicinal materials relates greatly to the clinical curative effect and security. In order to ensure the quality and safety of Chinese medicinal materials, a systematic and operable traceability system needs to be established. It can realize the whole process of quality and safety management of Chinese medicinal materials "from production to consumption" through recording and inquiring information and recalling defective products, which is an important direction for the future development of traditional Chinese medicine. But it is still at the exploration and trial stage. In this paper, a framework of Chinese medicinal materials' quality and safety traceability system was established on the basis of the domestic and international experience about the construction of food and agricultural products traceability systems. The relationship between traceability system of Chinese medicinal materials' quality and GAP, GMP, GSP was analyzed, and the possible problems and the corresponding solutions were discussed.

OBJECTIVETo evaluate the effect of aging on the proliferative and differentiation capacity of human periodontal ligament stem cells (PDLSCs).
METHODSHuman periodontal ligament tissues were obtained from surgically extracted third molars from 6 subjects aged 18-20 years (group A) and 6 subjects aged 45-50 years (group B). The proliferative capacity of PDLSCs isolated from the tissues was examined with MTT assay, and the osteogenic and adipogenic differentiation capacity of the cells were evaluated using alizarin red staining and oil red O staining. SA-βG expression was analyzed to assess the cell senescence. In both groups, PDLSCs were induced for osteogenic differentiation for 7 days, and the differentiation ability of the cells was assessed by examining alkaline phosphatase (ALP) activity and by detecting the expressions of osteocalcin (OCN) and ALP using Western blotting.
RESULTSHuman PDLSCs were successfully isolated from the 12 teeth and were characterized as MSCs. The PDLSCs derived from donors of different ages were all capable of osteogenic and adipogenic differentiation, but their proliferative and osteogenic differentiation capacity decreased with the donors' age. The cells also exhibited an age- related increase in adipogenic differentiation capacity and SA-βG expression. In both groups, the cells induced in osteogenic medium showed increased OCN expression and ALP activation, and the increments were more obvious in group A.
CONCLUSIONHuman PDLSCs can be isolated from periodontal ligament tissues even from donors of advanced ages, but their proliferative and differentiation capacity decreases and their adipogenic differentiation capacity increases with age.
