Objective To investigate the diagnostic significance of combined detection of rheumatoid factor (RF),anti-cyclic cit-rullinated antibody (anti-CCP antibody),glucose-6-phosphatase (GPI)and anti-RA33 antibody in rheumatoid arthritis (RA).Meth-ods One hundred and twenty-six patients with RA,60 patients with other autoimmune diseases and 60 healthy subjects undergoing physical examination were selected as the research subjects.The singled detection of RF,anti-CCP antibody,GPI and anti-RA33 an-tibody,and their combined detection were used to analyze their roles in RA diagnosis.Results Compared with the healthy control group,the four indexes in the RA group were increased,the difference was statistically significant (P<0.05),the RF level in the autoimmune diseases group was increased compared with the control group,the difference was statistically significant(P<0.05). Compared with the the autoimmune diseases group,the four indexes in the RA group were increased,the difference was statistically significant (P<0.05).The sensitivity and specificity of RF to RA were 77.77% and 63.33%;the sensitivity and specificity of anti-CCP antibody to RA were 69.04% and 95.00%;the sensitivity and specificity of GPI antibody to RA were 25.40% and 100.00%;the sensitivity and specificity of anti-RA33 antibody were 27.77% and 99.16%,respectively.The specificity of combined 2 indica-tors was increased from 63.33% to 85.00%,which of combined 3 indicators was increased to 93.33% and which of combined 4 in-dicators even reached to 100.00%.Conclusion The combination of RF,anti-CCP antibody,GPI and anti-RA33 antibody indicators greatly increases with the sensitivity and specificity for diagnosing RA and has clinical significance.

Objective To optimize a preparation technique of Pingfenggujin Granule. Methods The technique was determined by the orthogonal design with content of Astragalosides, polysaccharides and the rate of dried extracts. The contents of polysaccharides and Astragalosides were determined by UV and ELSD-HPLC respectively. Results The optimum water-extraction technique was to steep 2.5 h, ten times of water as much as weigh of total drugs and extract three times, 2 h each. Conclusion The optimum technique is feasible, and the method of content determination is accurate and reliable.

OBJECTIVE:To establish the method to control the quality of Qilian suppository.METHODS:TLC was per?formed to identify Rhizoma coptidis and Radix Notoginseng.A reverse phase HPLC-ELSD method was adopted to determine the content of ginsenoside Rg 1 and ginsenoside Rb 1 in Radix Notoginseng.RESULTS:The study on the quality control showed that the characteristic of identification by TLC was distinct and highly specific.In this quantification method,the linear ranges of ginsenoside Rg 1 and Rb 1 were1.56?g～3.74?g(r=0.9993,RSD=1.6%)and1.44?g～3.46?g(r=0.9981,RSD=1.2%)respectively.The average recovery rate of ginsenoside Rg 1 was99.10%,and RSD=1.6%(n=3);the average recovery rate of ginsenoside Rb 1 was102.13%,and RSD=1.2%(n=3).CONCLUSION:The method is simple,sensitive,accurate and re?peatable.It can be used for the quality control of Qilian suppository.

AIM: To determine astragaloside Ⅳ in Qixiu Granule (Radix Astragali seu Hedysari, Radix Salviae Miltiorrhizae, Radix Paeoniae Rubra, etc.) by HPLC ELSD. METHODS: HPLC ELSD was used in the quantitative analysis by using Alltima C 18 chromatography column and acetonitril water (34∶66) as a mobile phase. The flow rate of mobile phase was 1mL?min -1 . The tube temperature of the detector was 100?C. The flow rate of pure air was 2.7L?min -1 . RESULTS: The regressione quation was Y=-4.40?105+2.07?105X, r=0.9992 (3.73～13.59?g). The average recovery of astragaloside Ⅳ was 100.73%, RSD was 3.97%. CONCLUSION: The method is simple, reliable, accurate and can be regard as the quantity control method of Qixiu Granule.

Objective To compare the serum levels of interleukin(IL)-6,IL-18 and tumor necrosis factor alpha(TNF-α)in patients with DPD,PD,depression disorder and healthy controls and to analyze the correlations of serum inflammatory factors in DPD patients. Methods Serum levels of IL-6,IL-18 and TNF-αwere measured using enzyme linked immunosorbent assay(ELISA) kits. Several scales were performedin DPD patients. Results DPD,PD and depression disorder patients had significant lower baseline levels of IL-6 and TNF-αwhen compared to healthy controls(P < 0.05). The levels of IL-6 and TNF-α in DPD patients were significantly increased after 4 weeks of anti-depression treatment(P < 0.05). No difference of cytokines levels in gender and in severity of DPD patients was detected Serum levels of these inflammatory cytokines were not significantly correlated with the UP-DRS Ⅲ,H & Y,MMSE and HAMD scores in DPD patients. Conclusions Serum inflammatory factors(IL-6, TNF-α)were altered in patients with DPD in the earlier course of disease. However ,the role of IL-18 remained unknownin the occurrence of DPD disease.

Objective To investigate the effect of Yangxue Rougan pills on a rat model of liver fibrosis induced by multiple factors and the mechanism of action of Yangxue Rougan pills in the treatment of liver fibrosis. Methods A total of 50 male rats were randomly divided into blank control group, multi-factor model group, Fuzheng Huayu capsule group, and high-, middle-, and low-dose Yangxue Rougan pill groups. The rats in the blank control group were given normal water and feed, and those in the other groups were given modified high-fat low-protein diet and 5% alcohol, as well as subcutaneous injection of olive oil solution containing 40% carbon tetrachloride and intraperitoneal injection of pig serum 0.5 mL per rat, twice a week for 12 consecutive weeks. Since week 7, the rats in the high-, middle-, and low-dose Yangxue Rougan pill groups were given Yangxue Rougan pills at a dose of 9.5, 4.75, and 2.38 g/kg, respectively, those in the Fuzheng Huayu capsule group were given Fuzheng Huayu capsules at a dose of 0.75 g/kg, and those in the blank control group and the multi-factor model group were given an equal volume of distilled water by gavage every day for 6 consecutive weeks. The rats were treated at week 12. HE staining and Masson staining were used to observe the degree of liver fibrosis in rats, and PCR and Western blot were used to measure the expression of TGF-β1, Smad3, and Smad7 in the liver. A one-way analysis of variance was used for comparison of continuous data between multiple groups, and the Dunnett's t -test was used for further comparison between two groups. Results Compared with the blank control group, the multi-factor model group had a severely damaged lobular structure and a significantly higher degree of liver fibrosis, with the formation of pseudolobules with different sizes; compared with the multi-factor model group, the Yangxue Rougan pill groups had a significant improvement in the degree of liver fibrosis, with the most significant therapeutic effect in the high- and middle-dose Yangxue Rougan pill groups. Compared with the blank control group, the multi-factor model group had significant increases in the expression of TGF-β1 and Smad3 and a significant reduction in the expression of Smad7 in liver tissue (all P < 0.05); compared with the multi-factor model group, the Yangxue Rougan pill groups had a significant reduction in the expression of TGF-β1 and a significant increase in the expression of Smad7 (all P < 0.05); compared with the multi-factor model group, the high- and middle-dose Yangxue Rougan pill groups had a significant reduction in the expression of Smad3 (both P < 0.05). Conclusion Yangxue Rougan pills can significantly inhibit liver fibrosis in rats by downregulating the expression of TGF-β1 and Smad3 and upregulating the expression of Smad7, and therefore, the TGF-β1/Smad signaling pathway is one of the mechanisms of action of Yangxue Rougan pills in improving liver fibrosis.
