To study the characteristics of pharmacological effects of property combinations of traditional Chinese medicines (TCMs) distributing in the stomach meridian based on medicinal property combination, in order to further define the association relationship between properties of TCMs and their pharmacological effects, and build a bridge for the interpenetration and combination between the medicinal property theory of TCMs and their pharmacological effects. On the basis of the studies on the medicinal property theory of TCMs distributing along the kidney meridian and their pharmacological effects, efforts were made to collect relevant data for medicinal properties and pharmacological effects and mine the characteristics of pharmacological effects that were corresponding to relevant medicinal property combination by processing materials related to medicinal properties and pharmacological effects with the association rules method. According to the analysis, TCMs distributing along the kidney meridian with different medicinal property combinations were significantly differentiated in the pharmacological effects, but shared identical pharmacological effects, such as immunological enhancement. In this study, TCMs distributing along the kidney meridian with different medicinal property combinations were taken as the carriers to closely integrate the traditional Chinese medicine theory with the modem study achievements, lay a solid foundation for further developing and enriching the traditional Chinese medical property theory, while providing a new perspective on the development of modem medicine.

Objective To build a bio-material artificial chest wall and discuss its feasibility and efficiency in reconstruction of huge bony defects of chest wall in mongrels in comparison with traditional "sandwich" procedure. Methods (1) The procine osteal and membranate tissues were treated with epoxy cross linking method and their surfaces were modified with amino acid solutions at various concen-trations and at different temperatures to obtain an artificial pleura and artificial ribs for construction of the artificial chest wall. (2) The huge bony defects (5 cm×5 cm) were created in chest wall of five Chinese mongrels. (3) Three mongrels in test group was repaired with artificial chest wall, while two mongrels in control group was repaired with traditional "sandwich" complex. A follow-up was carried out to observe reconstruction effect and rejection in both groups at 3,6 and 12 months after implantation. Results There was no death found during the perioperative period and at 12 month follow-up in test group, with abnormal contour of chest wall and good thoracic activity after reconstruction. In the meantime, there found no rejection, collapse in the repaired region or paradoxical respiration. The postoperative X-rays at 3,6,12 and 24 months showed a good integrity of the thorax, with no collapse, deformation or abnormal movement. Meanwhile, the follow-up of control group showed a normal contour but slight collapse, with no paradoxical respiration. The Chest X-ray examination revealed that the bone cement in" sandwich" complex was X ray opaque and showed mild abnormal movement with breathing. The common blood test and immune items showed no abnormal. Conclusions The bio-material artificial chest wall is a safe and effective reconstruction technique for bony defects of thoracic wall in mongrels, with no acute or chronic rejection.

Objective To explore the impacts of Danhong injection on physiological and biochemical indicators in malnourished mice at physiological low doses, evaluate its safety, and test the practical value of safety re-evaluation of Traditional Chinese Medicinal ( TCM) injections. Methods A total of 32 ICR mice during growth period were selected to set up corn deficient nutrition mice model. Mice were assigned into the normal control group (given 0. 9% saline), Danhong injection at low, medium and high dosages (0. 2, 0. 4 and 0. 6 mL) groups (n=8 in each group);Mice were administered with respective medications intraperitoneally for 7 consecutive days. Blood samples were taken and mice were executed on the 8th day. All 9 kinds of organ or tissue were obtained completely, to measure related physiological and serum biochemical parameters. The safety of Danhong injection was evaluated by using Benefit and Damage Index - General Score ( BDI-GS ) system. Results The Danhong injection showed only slight damages on major organs or tissues, the BDI values were all above 0. 85, and the GS values were all above 9. 0;BDI values for Danhong injection at different dosages were all above 1. 0 for spleen and pancreas, showing better replenishing and healthy effects, and the differences were of statistical significance compared with the normal control group (P<0. 05 or P<0. 01). Meanwhile, it exerted obviously hypoglycemic effect. Conclusion Danhong injection is of rather low risk under physiological dosages, and therefore is safe to use. The mal-nutrition model combined with the BDI-GS system may be developed as a novel approach for safety re-evaluation of TCM injection in clinic.

OBJECTIVETo discuss the protective effect of alkaloids from Piper longum (PLA) in rat dopaminergic neuron injury of 6-OHDA-induced Parkinson's disease and its possible mechanism.

METHODThe rat PD model was established by injecting 6-OHDA into the unilateral striatum with a brain solid positioner. The PD rats were divided into the PLA group (50 mg x kg(-1) x d(-1)), the madorpa group (50 mg x kg(-1) x d(-1)) and the model group, with 15 rats in each group. All of the rats were orally given drugs once a day for 6 weeks. Meanwhile, other 15 rats were randomly selected as the sham operation group, and only injected with normal saline in the unilateral striatum. The behavioral changes were observed with the apomorphine (APO)-induced rotation and rotary rod tests. The number of tyrosine hydroxylase (TH)-positive cells in rat substantia nigra and the density of TH-positive fibers in striatum were detected by tyrosine hydroxylase immunohistochemistry. The content of superoxide dismutase (SOD), glutathione peroxidase (GSH-Px), glutathione (GSH), catalase (CAT), malondialdehyde (MDA), nitric oxide (NO) and nitric oxide synthase (NOS) in rat substantia nigra and striatum were measured by the spectrophotometric method.

RESULTAfter being induced by APO, PD rats showed obvious rotation behaviors, with decreased time stay on rotary rod and significant reduction in the number of TH-positive cells in sustantia nigra and the density of TH-positive fibers in striatum. The activities of SOD, GSH-Px, CAT, the content of GSH and the total antioxidant capacity significantly decreased, whereas the activities of NOS and the content of MDA, NO significantly increased. PLA could significantly improve the behavioral abnormality of PD rats and increase the number of TH-positive cells in sustantia nigra and the density of TH-positive fibers in striatum. It could up-regulate the activities of SOD, GSH-Px, CAT, the content of GSH and the total antioxidant capacity, and decrease the content of NOS and the content of MDA, NO.

CONCLUSIONAlkaloids from P. longum shows the protective effect in substantia nigra cells of 6-OHDA-induced PD model rats. Its mechanism may be related with their antioxidant activity.

Pancreatic cancer is a highly lethal disease in gastrointestinal malignant tumors.The mortality of pancreatic cancer closely parallels its incidence.Most patients with pancreatic cancer remain asymptomatic until the disease reaches an advanced stage.There is no program for screening patients at high risk of pancreatic cancer.Although CT,MRI,positron emission tomography,endoscopic ultrasonography,and endoscopic ultrasonography-guided fine-needle aspiration offer high diagnostic ability for pancreatic cancer,it cannot be found at the early stage easily.Surgical resection is regarded as the only potentially curative treatment and adjuvant chemotherapy is given after surgery.This article reviews epidemiology,risk factors,diagnosis and treatment for pancreatic cancer by summarizing relevant literature.

Objective To study the significance and value of imaging typing by analyzing the correlation between contrast-enhanced ultrasound perfusion imaging typing and vascularization in patients with primary hepatocellular cancer.Methods The early enhanced arterial phase reflecting angioarchitecture,and the size and edge of enhanced tumor closely related to microvessel distribution, position and density, were observed and analyzed in 89 patients (113 lesions).All the cases were pathologically proved, and some received immunohistochemisty staining and the microvessel density were recorded.Results The perfusion imagings were classified into 4 types according to changes on contrast-enhanced ultrasound,dendritic,mixed,circular and net-like type.Atypia vessels were commonly seen in dendritic type,and Ⅲ and Ⅳ accounted for 79.1%.The microvessel density was higher than the other types.The circular type was relatively regular and Ⅲ and Ⅳ accounted for 12.5%.The microvessel density was lower than the other types.Combined with the contrast-enhanced ultrasound perfusion imaging and compared with pathological grading,growing methods and microvessel density, the dendritic type was characterized by infiltrative growth, and had strong invasion tendency.The circular type was characterized by expansive growth.And the other two types were characterized by transitional type.Conclusions Contrast-enhanced ultrasound can reflect the angioarchiteeture, the microvessel density and the position,and it is related to the pathological grading and growing methods.
