Objective:To study the effects of n-Butanol Extract (BEX)of Xanthoceras Sorbifolia Bunge on rat model with adjuvant arthritis(AA) in rats and its mechanism .Methods: Rat model of adjuvant arthritis(AA) was induced by FCA. Hind paw swelling was observed to evaluate the effect of BEX and phagocytic function of monocyte-macrophage system, antibody level and delayed hypersensitivity were examined to explore its mechanism. Results: BEX can inhibit the primary and secondary hind paw edema and improve the general symptoms (P

The effect of histamine on cardial vascular ,gland,tumor and allergic reaction were reviewed and the development of its antagonist is summarized.

AIM: To study the pharmadynamics in association with the clinical effect of Fufangdaqinye Mixture. METHODS: The method of this study included anti fever, anti inflammatory and anti bacteria experiment. RESULTS: Fufangdaqinye Mixture was quite effective for the fever induced by endotoxin in rabbit, and preserved those mice from death caused by abdominal injection of staphylococcus aureus and itemophilus influenze and had a effect against staphylococcus aures, hemophilus influenze, peumococcus and streptococcus A and B. Fufangdaqinye Mixture could significantly inhibit the foot swelling and significantly inhibit the increased penetrability of abdominal capillary vessel induced. CONCLUSION: Fufangdaqinye Mixture has a curative effect of anti fever, anti bacteria and anti inflammation.

Objective To investigate the biokinetics of 131 I and its absorbed dose in patients with metastatic DTC. Methods Forty?one patients with metastatic DTC who were referred to 131 I therapy were prospectively recruited from September 2009 to September 2011. Scintigraphic images were serially acquired after the ingestion of 131I (3.70-9.25 GBq) to assess the biokinetics. CT was used to measure the masses of the DTC lesions. Calculation of absorbed doses to DTC lesions was based on the Medical Internal Radiation Dosimetry formula of the Society of Nuclear Medicine and Molecular Imaging. Kruskal?Wallis rank sum test was used to compare the differences of absorbed dose among different tumor deposits. Results In total, 59 io?dine?avid metastatic lesions (35 in cervical lymph node, 17 in lung and 7 in bone) in 41 patients were evalu?ated and the mean absorbed dose of DTC lesions was (10.4±6.5) Gy/GBq, with range of 0.1 to 136.2 Gy/GBq. The median absorbed dose was 11.3 Gy/GBq for lymph node metastase, 10.1 Gy/GBq for lung metastases and 9.6 Gy/GBq for bone metastases. There were no statistically significant differences in absorbed doses a?mong the metastases of lymph node, lung and bone ( Z=0.907, P>0.05) . Conclusion A wide inter?lesion variation of absorbed dose to metastatic DTC is observed.

OBJECTIVE: To determine imperatorin as the active ingredient of Angelica dahuricae in Jiedu tongqiao pills by HPLC. METHODS: The separation was performed on Waters Symmetryshielb33 C18(250 mm?4.6 mm,5 ?m) column with detection wavelength of 248 nm. The mobile phase consisted of methanol-water (65 ∶ 35) with flow rate of 1.0 mL?min-1.RESULTS:The linear range of imperatirin were 0.15～1.35 ?g. The average recovery was 100.4%(RSD=1.89%,n=9).CONCLUSION: The method is simple, accurate and reproducible for quality control of Jiedu tongqiao pills.

Fifty Cases of chronic B—hepatitis were treated withTCM based on differentiation of syndromes and com-pared with a control group of 50 cases treated withwestern remedies.Results showed that for the treatinggroup,the rate of negative return of HBeAg was64%,and the rate of positive return of HBe was 48%,while that of the control group were 20% and 10% re-spectively.

Nonunion remains a major complication after skeletal trauma. In the last decade, extracorporeal shock wave therapy has become a common tool for the treatment of delayed unions or non-unions. With the help of a review of the literature, the current author gave an overview of indications, choices of devices, success rates and complications for ESWT in the treatment of non-unions. The conceivable mechanism was also outlined.

OBJECTIVEThis study further explores the stromal cell-derived factor-1 (SDF-1)/chemokine receptor 4 (CXCR4) signaling axis mechanism in temporomandibular joint osteoarthritis (OA) by detecting the changes in CXCR4, interleukin (IL)-6, and collagen X expression in the ATDC5 cell line stimulated by the cyclic tensile strain and SDF-1.

METHODSInsulin-transferrin-selenium (ITS) was used to induce ATDC5 cells to differentiate into chondrocyte-like cells. After three weeks, the cells were divided into two groups: those with and without cyclic tensile strain. These groups were further divided into the negative control and SDF-1 groups. Strain force of 20% was applied. After 12 h, the total proteins were extracted from cells of the four groups, and Western blot analysis was used to detect the changes in CXCR4, IL-6, and collagen X expression.

RESULTSSDF-1 could enhance CXCR4, IL-6, and collagen X expressions in the chondrocytes, and 20% tensile strain force could further upregulate the three factors.

CONCLUSIONUnder abnormal tensile force, SDF-1 can upregulate its specific receptor CXCR4, thus increasing its-binding efficiency and resulting in the activation of the SDF-1/CXCR4 axis. This condition enhances the expressions of IL-6 and other inflammatory factors and directly damages to cartilage tissue. Such damage directly promotes chondrocyte hypertrophy, which enhances collagen X expression.
