BACKGROUND:Studies have found that Wudi Dan can suppress local inflammatory response of the lesioned joints to protect the articular cartilage. OBJECTIVE:To verify the effect of Wudi Dan on chondrocyte viability and apoptosis as wel as the therapeutic effect on osteoarthritis. METHODS:Rat chondrocytes were cultured in serum medium containing Wudi Dan, and the effects of Wudi Dan on cel viability and apoptosis were observed by comparison with the control group. Rabbit model of knee osteoarthritis was constructed using modified Hulth method. Rabbit models were divided into two groups:Wudi Dan group treated with Wudi Dan and control group treated with normal saline, twice a day, consecutively for 4 weeks. Therapeutic effect of Wudi Dan on knee osteoarthritis was observed;cel viability and apoptosis were observed under microscope;the levels of interleukin-1 and matrix metal oproteinase-3 were determined using immunohistochemical method. RESULTS AND CONCLUSION:The apoptotic rate of chondrocytes was significantly lower in the Wudi Dan group than the control group. Pathological findings of the rabbit knee joints showed that the control group had more severe damage to the articular cartilage than the Wudi Dan group. Immunohistochemical staining revealed that in the Wudi Dan group, the cytoplasm and extracel ular matrix were colored light and there were a smal number of positive cel s as wel as low expression of interleukin-1 and matrix metal oproteinase-3. The results suggest that Wudi Dan can effectively protect against articular cartilage lesions, reduce inflammation, and have a good therapeutic effect on osteoarthritis. Its mechanism may be related to inhibition of chondrocyte apoptosis, reduction of cytokine production and inhibition of protein expression of matrix metal oproteinase.

OBJECTIVETo explore the effect differences between twirling-rotating reinforcing and reducing technique of acupuncture on cardiac damage in spontaneous hypertensive rats (SHR).
METHODSSixty male 11-week-old SHR were randomly divided into four groups: a model control group (group A), a twirling-rotating reinforcing technique group (group B), a twirling-rotating reducing technique group (group C) and a needle retaining group (group D), 15 rats in each one. In addition, twelve male 11-week-old Wistar rats were used as a blank control group (group E). Acupuncture was not used in group A and group E, only with grasp, capture and binding stimulation that was also adapted in the rest groups. Rats in the group B were treated with acupuncture at "Taichong" (LR 3) by twirling-rotating reinforcing technique for 1 min and then the needles were retained for 9 min; rats in the group C were treated with acupuncture at "Taichong" (LR 3) by twirling-rotating reducing technique for 1 min and then the needles were retained for 9 min; rats in the group D were treated with acupuncture at "Taichong" (LR 3) but without any technique and then needles were retained for 10 min. Before and after acupuncture, blood pressure monitor was used to measure the rats' systolic pressure and diastolic pressure every 6 days. Twenty-eight days after the treatment, HE and Masson staining were adopted to observe the status of left ventricular hypertrophy and myocardial fibrosis. ELISA method was applied to test the content of endothelin-1 (ET-1). PCR semiquantitative method was used to analyze Type I and III collagen mRNA in the left ventricular.
RESULTS(1) Blood pressure: after the treatment, the systolic pressure and diastolic pressure were both increased in the group A and the group B (P < 0.05); while the two pressures were both lowered in the group C and the group D (P < 0.05), which was more obvious in the group C (P < 0.05). (2) According to HE and Masson staining, except for the group E, the myocardial hypertrophy and fibrosis could be found in the rest groups, in which the group C was the modest, followed by the group D, while the group A and the group B were more severe. (3) Concentration of ET-1: there were differences of concentration of ET-1 among 5 groups (P < 0.05), and the concentration value from high to low was the group A, B, C, D and E. (4) Type I collagen mRNA: the difference of level of Type I collagen mRNA between group C and D was not statistically significant (P > 0.05); compared with the group A and B, the level was lower in the group C; the level was the lowest in the group E. Type III collagen mRNA: the difference between the group A and B was not statistically significant (P > 0.05); compared with the group A, B and D, the level was lower in the group C.
CONCLUSIONThe twirling-rotating reducing could reduce the systolic pressure and diastolic pressure in SHR, effectively prohibit the production of ET-1 and expression of Type I and III collagen mRNA, and it has more obvious inhibiting effect on Type III collagen mRNA. There is biological effect difference between twirling-rotating reinforcing and reducing technique.

Gindenosides are the active ingredients of Panax ginseng. 20 (S) -protopanaxadiolocotillol type epimers are the main metabolites of 20 (S) -protopanaxadiol. The previous studies showed that there are stereoselectivity difference in pharmacodynamics and pharmacokinetics between 24R-epimer and 24S-epimer. The purpose of this study was to explore the excretion of the epimers in bile, feces and urine of rat. Liquid chromatography tandem mass spectrometry method has been performed for determination of 24R-epimer and 24S-epimer in bile, feces and urine. 24R-epimer or 24S-epimer was intragastric administered to rats at a single dose of 10 mg x kg(-1). Results showed that after administration the recovery of 24R-epimer and 24S-epimer in feces was 17.69% and 17.09%, respectively, while both of the two epimers were hardly detected in urine. The 48 h cumulative biliary excretion rate of 24R-epimer was 8.01% after administration, while only 1.47% for 24S-epimer. It indicated that there are stereoselectivity in biliary excretion of the epimers with intragastric administration.

Objective To investigate the effect of bortezomib with arsenic trioxide different concentration on the cell cycle and apoptosis of Raji cells. Methods Flow cytometry analysis showed that the relative number of cells in different phases and the percentages of cells calculated in G1 and S phase of the cell cycle and apoptosis were assessed after treatment with As2O3 and BOR or in combination with BOR in different concentration at indicated time (24 h, 48 h, 72 h). Results Flow cytometric analysis showed that the cell cycle was arrested at G1 phase, the number of cells G1 period increased significantly, and S phase decreased on Raji cells after As2O3 treatment. The relationship between the cellular DNA contents and the concentration of As2O3 showed a dose-and time-dependent manner (P <0.0001). But it was found that BOR had no effect on Raji cell cycle, but, in two drugs combination, cell apoptosis rate significantly increased from 16.98 % to 45.84 %. Conclusion The results show that As2O3 exerted variable and definite effects on lymphoma Raji cells, which indicated that As2O3 might induce apoptosis and arrest cell cycle. The combination of two drugs had a effective and synergistic effect on apoptosis.
