RESUMO
Objective To explore the clinical effect of Tongbi capsule combined with acupuncture for the patients with knee osteoarthritis and explore the mechanism of inflammatory response and hemorrheology. Methods According to the random table method, 88 KOA patients in our hospital from February 2016 to January 2017 were divided into the control group and the research group with 44 in each group. Patients in the control group were treated bycelecoxib capsule, while the patients in the research group were treated by Tongbi capsule combined with acupuncture. The treatment courses of two groups were two months. The clinical total effective rate of two groups of patients were compared after treatment. At the same time, the osteoarthritis index visual scale (WOMAC) and morning stiffness, joint tenderness index score were detected and compared after the treatment.The levels of serum tumor necrosis factor-α(TNF-α), interleukin (IL)-1β and IL-6 were detected by enzyme linked immunosorbent assay before and after the treatment. The hemorheology indexes were tested by automatic biochemical analyzer. In addition, the incidence of adverse reactions of two groups of patients was observed during treatment. Results The clinical total effective rate of the research group was 93.18％ (41/44), which was significantly higher than the control group72.73％ (32/44), and the difference was statistically significant (χ2=6.510, P=0.011). After treatment, the WOMAC (31.26 ± 6.12 vs. 36.17 ± 7.09, t=-3.477), joint tenderness index (1.75 ± 0.46 vs. 2.11 ± 0.54, t=-3.366) and morning stiffness score (1.62 ± 0.53 vs. 2.14 ± 0.51, t=-4.690) of the research group were significantly lower than those of the control group (P<0.05). The levels of TNF-α (7.36 ± 1.45 pg/ml vs. 8.02 ± 1.54 pg/ml, t=-2.070), IL-1β (27.82 ± 5.22 μg/ml vs. 33.05 ± 5.17 μg/ml, t=-4.722), IL-6 (2.81 ± 0.58 ng/ml vs. 3.34 ± 0.53 ng/ml, t=-4.475) of the research group were significantly lower than those of the control group (P<0.05). The whole blood high shear viscosity (12.09 ± 3.46 mPa?s vs. 14.22 ± 3.51 mPa?s, t=-2.867), whole blood low shear viscosity (2.53 ± 0.68 mPa?s vs. 3.32 ± 0.71 mPa?s, t=-5.330), whole blood viscosity (1.35 ± 0.29 mPa?s vs. 1.60 ± 0.41 mPa?s, t=-3.302), erythrocyte sedimentation rate (7.10 ± 2.06 mm/h vs. 8.02 ± 2.13 mm/h, t=-2.059), fibrinogen (2.71 ± 0.53 g/L vs. 3.42 ± 0.65 g/L, t=-5.615) and erythrocyte deformation index (0.57 ± 0.16 vs. 0.71 ± 0.19, t=-3.739) of the research group were significantly lower than those of the control group (P<0.05). The incidence of adverse reactions of control group was 11.37％ (5/44), while the incidence of adverse reactions of resarch group was 6.82％ (3/44), which the difference of the incidence of adverse reactions between two groups showed no statistical significance (χ2=0.550, P=0.458). Conclusions The Tongbi capsule combined with acupuncture can reduce the degree of inflammation, and also improve hemorheology indexes of KOA patients.
RESUMO
An analytical method based on ultra performance liquid chromatography-tandem mass spectrometry was developed for the determination of cyantraniliprole and its main metabolite J9 Z38 residues in pepper and soil. The fate of cyantraniliprole and J9Z38 in pepper and soil was also evaluated. The target compounds were extracted with acetonitrile, cleaned up by C18 cartridge, and further analyzed by gradient ultra performance liquid chromatography-tandem mass spectrometry with electrospray ionization in positive mode ( ESI﹢) using a UPLC BEH C18 Column. The method was validated using fortified pepper and soil. Intra-day mean recoveries of cyantraniliprole and J9Z38 at three spiked levels (0. 01, 0. 10 and 1. 00 mg/kg) ranged from 88. 6% to 105 . 7% with relative standard deviations of 3 . 8%-15 . 1%. Inter-day mean recoveries of cyantraniliprole and J9 Z38 were found between 91 . 4% and 105 . 3% with relative standard deviations of 4 . 9%-12 . 3% at three spiked levels. Limits of quantification ( LOQs) of cyantraniliprole and J9Z38 were 0. 1 and 0. 2 μg/kg, respectively. Linear calibration functions with correlation coefficients of r>0. 9992 were obtained in the concentration range of 2. 0-128. 0 μg/L. This method was applied to the analysis of cyantraniliprole and J9Z38 residues in real pepper and soil samples selected from field. The results of the residue dynamic experiment showed that the half-life of cyantraniliprole ranged from 9 . 2 to 11 . 2 days in pepper and from 9 . 2 to 20. 8 days in soil. While, the residues of J9Z38 in pepper were below LOQ, and the half-life of J9Z38 in soil was 9. 4 days. The degradation speed of cyantraniliprole increased with the increase of the precipitation.
RESUMO
Objective To evaluate the efficacy of double filtration plasmapheresis (DFPP) in the treatment of patients with refractory rheumatoid arthritis (RA). Methods Eighty-two patients were randomly aesigned,42 to the DFPP group and 40 to the no-DFPP group. All patients previously experienced an incomplete response to 2-3 dis-ease-modifying antirheumatic drugs (DMARDs) and 1-2 nonsteroidal anti-inflammatory drugs (NSAIDs) or predni-sene. All patients received sulphasalazine (SASP,0.75 g three times daily) plus methotrexate (MTX, 10 mg orally once weekly). DFPP was performed once a week for 2-3 sessions. A total of 121 plasmapheresis procedures were per-formed in 42 patients. Control patients did not receive sham DFPP. The efficacy measures recorded one day after the final treatment and latest month in follow up for 12～24 months included the American College of Rheumatology 20% ,50% ,and 70% improvement criteria (ACR20, ACR50, and ACR70), the Health Assessment Questionnaire estimate of disability (HAQ); and the disease activity index. Results Patients in the DFPP group had ACR 20, ACR 50 and ACR 70 improvements of 100% ,92.9% and 81.0%,as compared with the patients in no-DFPP group 17.5% ,0,and 0 (P<0.001). Significant change from baseline was observed in HAQ scores in the DFPP group but not in the no-DFPP group (P<0.001). The changes from baseline in the disease activity scores were significantlygreater than in the no-DFPP group (P<0.001). Conclusion DFPP therapy significantly alters the signs and symp-toms of refractory RA. There are significant increases in physical function and improvement in quality of life.
