Objective To explore the variation of the main chemical constituents of Herb Epimedii in decocting Herb Epimedii and Radix Astragali separately and compatibly. Methods Herb Epimedii combined with Radix Astragali were decocted with water in which the proportion of them were 1∶0, 2∶1, 1∶1, 1∶2 and 0∶1, respectively. RP-HPLC was used to compare the content of icariin and the fingerprints in separate and compatible decoction. Results Afeter combination, the number of chromatographic peaks were added and no new peaks were detected. The contents of some chemical constituents such as icariin in Herb Epimedii were increased, especially in the compatible decoction at the proportion was 1∶1. Some constituents were not changed obviously. Conclusion Herb Epimedii decocted together with Radix Astragali especially at a ratio of 1∶1 can increase the solubility of the chemical constituents in Herb Epimedii. This provides a scientific basis for more effective use of the compatible decoction of the two herbs.

Objective To investigate the clinical effect of sodium hyaluronate combined with glucocorticoid on the treatment of periarthritis of shoulder.Methods106 patients in department of orthopedics, the second hospital of Ningbo with periarthritis of shoulder were randomly divided into 2 groups (n=53).The control group were treated with anti-inflammatory and analgesic treatment, at this basis, the study group were treated with sodium hyaluronate combined with Glucocorticoid.5 weeks for a course of treatment.Levels of serum inflammation, laboratory-related indicators were compared.ResultsCompared with before treatment, shoulder joint activity in the two groups increased, VAS score decreased, the scores of strength of shoulder joint, range of motion and daily activities increased, levels of serum IL-6, IL-10, TNF-α decreased(P<0.05).Compared with the control group, scores of activity in the study group were higher, VAS scores were lower, scores of strength of shoulder joint, range of motion and daily activities were higher, levels of serum IL-6, IL-10, TNF-α were lower(P<0.05).The effective rate in the control group(73.59%) was lower than the study group(90.57%), but there was no statistical difference.ConclusionThe effect is accurate which sodium hyaluronate combined with glucocorticoid was used in the treatment of periarthritis of shoulder, and it can reduce the inflammation index and improve the joint activity.

Objective To establish a methodological study pattern of quantitative analysis of multi-components by single marker ( QAMS) , and examine its feasibility and technical applicability in the quality control of compound preparation of traditional Chinese medicine-Jinhoujian spray. Methods Gas chromatographic method ( GC) was used and naphthalene served as the internal standard. Menthol was used as the reference substance.

BACKGROUND: Now, Shock Wave Therapy is used to cure the ununion and delayed union of bone, the avascular necrosis of the femoral head and the chronic injury of locomotor system, what has got a good curative effect. But, the mechanism is not clear. OBJECTIVE: To investigate the expression of c-Fos, c-Jun protein in human bone marrow mesenchymal stem cells (BMSCs) Influenced by shock wave.DESIGN, TIME AND SETTING: Randomized group, the controlled study was performed at the State Key Laboratory of Pathology, College of Basic Medicine, Jilin University, from March 2007 to March 2008. MATERIALS: Bone marrow was obtained from healthy volunteers.METHODS: Human BMSCs were cultured in vitro. And the fourth generation cells were digested into cell suspension with 2.5 g/L trypsin and adjusted at a density of 1.0×10~9/L with DMEM-LG. Then, the cells were divided into 6 1.5-mL Eerrendorf tubes, one was control group and the other five were experimental groups. The experimental groups were treated with an optimal dose of shock wave (8.5 kV, 120 times) by liquid-electric shock wave lithotripsy. Then the protein was extracted at different time points (5, 15, 30 minutes, 1, 2 hours) after treatment.MAIN OUTCOME MEASURES: Inverted microscope was used to observe the morphologic feature of BMSCs. The growth curves were charted by MTT method. The change of activations of c-Fos, c-Jun were tested by western blot. RESULTS: ①BMSCs were seeded in culture plate. The cells began to divide and proliferate slowly 24 hours later, and became fusiform shape after adhering to the wall. 3 days later, the speed of proliferation quickened, and cells accumulated colony. At day 10-14, the number of hMSCs grew till they covered the bottom of the culture plate. The round passage hMSCs adhered to the wall completely in 24 hours, which were similar to primary cells. The cells connected together during one week, and showed vortex-like. The speed of proliferation became slower and the cells became older when hMSCs were passaged to the tenth generation. ②MTT method showed that the growth curve of original, P2, P3 hMSCs looked like S shape, and the third to fifth days were growing period. ③The phosphorylation level of c-Fos and c-Jun began to increase after induced by shock wave and reached a peak at 30 and 15 minutes, respectively. And their phosphorylation level were 2.56-fold and 1.68-fold (P < 0.01) compared with the average level in control groups, respectively. Then they began to decrease. There was no apparent change in the total dose (P > 0.05). CONCLUSION: Following the treatment of shock wave, the activations of c-Fos and c-Jun in BMSCs increased.
