OBJECTIVE:To provide reference for standardizing the names of TCM from Rumex. METHODS:According to lit-erature research,the most frequently used names (such as Jinbuhuan,Tudahuang,Yangti) of TCM in Rumex were combed,and suggestions for existing problems were put forward. RESULTS & CONCLUSIONS:The TCM names were used confusedly,main-ly showing that inconsistent names of TCM from the same plant in different areas,same name of TCM from different plants in the same area,same name of TCM from different plants in different areas. The key to solving the confused use of names of TCM in Rumex is standardization and unification of medicinal plant source and names. It can be developed and solved in order by resource investigation and identification,establishing quality standard and excavating medicinal value,in which,conducting the resource in-vestigation and specie identification,determining the medicinal names,stipulating the official names and establishing the quality standard are the important work in future.

To investigate the diagnosis and surgical treatment of inraspinal tumors.
The clinical data of 246 patients with inraspinal tumors who had undergone operations in the Affiliated Hospital of Qingdao University Medical Col ege between January 2010 and January 2013 were retrospectively analyzed. The treatment and prognosis of inraspinal tumors were reviewed.
262 operations were performed, with posterior bilateral laminectomy approach in 202 cases, semi-laminectomy approach in 28 cases, laminoplasty approach in 10 cases, and lateral resection of extra-vertebral canal dumbbel shaped tumors in 22 cases. The short-term remission rate of the nerve root pain reached 95.0%(133/140), and the improvement rates of the sensory disability, motor disturbance, and sphincter dysfunction were 85.6%(125/146), 86.7%( 136/157), and 84.6(11/13) respectively. The ASIA nervous function scores and grades at the last fol ow-up were significantly superior to those before and 3 months after the operation in 236 patients.
Intraspinal tumors are mostly benign. The clinical appearance of them should be watched closely, and thorough physical check-up should be performed. MRI is the examination of choice at early diagnosis. The key to improve the treatment effects is to perform operations as soon as possible.

BACKGROUND:The most effective method for the treatment of acetabular fracture is open reduction and internal fixation, however, this treatment for some special types of acetabular fracture cannot get satisfactory prognosis, and is prone to complications, such as traumatic coxarthrosis and avascular necrosis of femoral head. OBJECTIVE:To evaluate the curative effect of open reduction and internal fixation and total hip arthroplasty in the treatment of special acetabular fracture. METHODS:Twelve cases of acetabular fracture were included, including seven cases of traffic accident wound, three cases of crush injury, and two cases of fal ing injury. The type of bone fracture:two cases of posterior wal fracture, two cases of posterior column and posterior wal fracture, one case of T shaped fracture, five cases of transverse and posterior wal fracture, and two cases of acetabular roof sexual fracture. Complications:one case was femoral head centric dislocation, five cases were latter dislocation, and three cases were caput femoris fractures. Before injury, three cases had coxarthrosis, and two cases were avascular necrosis of femoral head. Al the cases were treated with open reduction internal fixation and total hip arthroplasty, of which nine cases were treated with biological prosthesis, and three cases were treated with bone cement prosthesis. The time from hospitalization to surgery was 3-15 days, and average was 6 days. The patients were fol owed-up once every 2 months in 1 year after replacement, and the Harris score was used to evaluate the hip function recovery. RESULTS AND CONCLUSION:No surgical site and deep wound infection, joint dislocation, lower limb deep vein thrombosis, and death were found in these 12 cases. Among them, 11 cases were fol owed-up for a longtime;the fol ow-up was lasted for 6-82 months. The acetabular fracture was healed at 6-16 months after reduction without prosthesis loosening and sinking. The hip function was evaluated during final fol ow-up according to the Harris score:excellent in eight cases, good in two cases, poor in one case, and the excellent and good rate was 91%. Open reduction internal fixation and one-stage total hip arthroplasty can avoid long-term bed, get out of bed as soon as possible, and reduce complications, thus reconstruct the hip joint painlessly and good functional y.

Objective To investigate the in vitro inhibitory effects of regulatory T cells ( Treg ) from unpregnant mice and pregnancy-induced regulatory T cells ( piTreg) on the proliferation of na?ve T cells and their differences .Methods The numbers of piTreg cells from allogeneic pregnant mice ( C57/B6 fe-male×BALB/c male) on day 12.5 (E12.5d) of gestation and Treg cells from unpregnant C57/B6 mice were detected respectively by flow cytometry .The percentages of piTreg cells and Treg cells in CD 4+T cells of age-matched female mice and their intracellular expression of Foxp 3 were analyzed .The in vitro inhibitory effects of piTreg cells and Treg cells on the CFSE-labeled na?ve T cells ( effector cells ) were compared in a one-way mixed lymphocyte culture system using mitomycin C-inactivated CD4-T cells as stimulator cells . Results The level of piTreg cells in splenic mononuclear cells was significantly higher than that of Treg cells (P<0.001) from normal mice.Foxp3 was highly expressed in both piTreg cells and Treg cells , howev-er slightly increased in piTreg cells .Moreover , piTreg cells had a significant stronger in vitro inhibitory effect on na?ve T cells proliferation than that of Tregs cells (P<0.006), which was in a cell-dependent manner. Conclusion The present study suggests that the piTreg cells have a stronger inhibitory effect on na ?ve T cell proliferation as compared with Terg cells from unpregnant mice , The differential activity of CD 4+CD25+Treg might be mediated by the paternal antigens during pregnancy .

Odor and taste are characteristic properties of traditional Chinese medicine (TCM). They are closely related to the chemical compositions in TCM. They are also the outer reflection of TCM quality and an important part of the character identification. This article reviewed the current research on odor and taste identification of TCM, which indicated that odor and taste identification had not been paid enough attention to and its research lagged behind modern social development. Based on current analytical techniques and methods, this article proposed a new idea for odor and taste identification of TCM. The idea emphasized the objectification of odor and taste and TCM identification research should be combined with chemical components analysis.
