Andrographolide Benefits Rheumatoid Arthritis via Inhibiting MAPK Pathways.

Andrographolide (AD) is the main compound distributed in medicinal herb Andrographis paniculata and exhibits anti-inflammatory activity. AD has been used for the treatment of multiple inflammatory diseases. However, the therapeutic value of AD on human rheumatoid arthritis (RA) remains unclear. In this study, we investigated the effects of AD on collagen-induced arthritis (CIA) and human RA synovial fibroblasts (RA-SFs). CIA mice were treated with AD (dissolved in 0.5% CMC-Na, 100 mg/kg per day) or vehicle (0.5% CMC-Na) daily by oral gavage for 2 weeks. The arthritis severity and joint destruction were assessed. Serum anti-collagen II antibody (anti-CII Abs) and cytokines were determined by ELISA. TNFα-stimulated human RA-SFs were treated with varying doses of AD for in vitro investigation. Results showed that AD significantly attenuated the arthritis severity and joint damage. AD treatment significantly reduced the production of serum anti-CII, TNFα, IL-1ß, and IL-6. In vitro, AD decreased the secretion of IL-1ß and IL-6 from TNFα-stimulated RA-SFs in a dose-dependent manner. AD treatment reduced the TNFα-induced phosphorylation of p38 MAPK and ERK1/2 in a dose-dependent manner. Thus, our findings suggest that AD confers protective effects on autoimmune arthritis through inhibiting MAPK pathways.

[Establishing a minimum data set of soil quality assessment for cold-waterlogged paddy field in Fujian Province, China].

The yields of cold-waterlogged (CW) paddy fields widely spreading in Jiangnan mountainous areas are moderate or low but have a high potential to be increased. Based on data including 41 soil characteristics of 17 pairs of typical surface soils of cold-waterlogged paddy field and non cold-waterlogged (NCW) paddy field at a neighboring landscape unit in Fujian Province, various index differences of soil properties and causes between CW paddy field and NCW paddy field were systematically studied, and a minimum data set (MDS) of soil quality assessment for CW paddy field was established by principal component analysis. By pair analysis, soil characteristics of CW paddy field showed that the content of organic matter increased by 31.7%, but the microbial biomass C decreased by 37.8%, which belonged to active soil organic matter component. The content of ferrous iron (Fe2+) increased by 177.0%, but the available phosphorus (P) and potassium (K) decreased by 52.3% and 22.8%, respectively. Catalase and invertase activities increased by 58.3% and 22. 1%, but phosphatase, nitrate reductase activities and microflora decreased by 47. 8%, 66.6% and 29.8%-46.0%, respectively. The sand content increased about 8.0%, but the water immersed bulk density decreased by 25.8%. There were significant differences of indices for 28 of all 41 soil characteristics. Five principal components cumulatively exhibiting about 78.5% contribution were concluded from the 28 soil characteristics to reflect characteristics related to soil biochemistry, active organic nitrogen, reducing barriers, physical and chemical nutrients, respectively. Eventually, correlation analysis combined with expert experience method were applied to optimize MDS containing six factors for soil quality assessments, including C/N, bacteria, microbial biomass N, total reducing agents, physical sand and total P.

[Value of cerebral spinal fluid measurement of hypocretin-1 in the diagnosis of Chinese patients with narcolepsy].

OBJECTIVE: To evaluate the diagnostic value of cerebral spinal fluid (CSF) measurement of hypocretin-1 (hcrt-1) in Chinese patients with narcolepsy. METHODS: A total of 139 narcoleptic patients, including 111 narcolepsy with typical cataplexy (NC) and 28 narcolepsy without cataplexy (NWC), were diagnosed at the sleep centre of Peking University People's Hospital from April 2003 to March 2012. And 64 non-narcoleptic controls were recruited. CSF hcrt-1 levels were measured in all subjects.Receiver operating characteristic curve (ROC) was applied to determine the cutoff value of hcrt-1 for Chinese narcoleptic patients. The diagnostic utility of hcrt-1 ≤ 110.0 ng/L and hcrt-1 ≤ 30% of mean normal level defined by International Classification of Sleep Disorders-II and the new Chinese cutoff value were evaluated respectively. RESULTS: The level of hcrt-1 in narcolepsy patients was significantly lower than that of normal controls and the NC group was even lower than NWC group (20 (13, 36) vs 319 (244, 379) and 36 (15, 114) ng/L) (all P < 0.01).Using the international criteria of CSF hcrt-1 ≤ 110.0 ng/L or a level of 1/3 of mean normal control values, a specificity of 100% and sensitivity of 90.6% were generated.ROC curve indicated that CSF hcrt-1 level of 138.0 ng/L was the best cutoff value for the diagnosis of narcolepsy in Chinese narcoleptic patients. There were a specificity of 100%, a sensitivity of 92.8% and the area under the ROC curve of 0.98. CONCLUSIONS: CSF hcrt-1 measurement with high specificity and sensitivity is a useful diagnostic tool for Chinese narcoleptics. And the level of 138.0 ng/L may be the optimal cutoff for the diagnosis of narcolepsy in this group of patients.

[Comparison on efficacy and the safety evaluation on peripheral facial paralysis treated with electroacupuncture of different waveforms].

OBJECTIVE: To use electroacupuncture (EA) of different waveforms to treat peripheral facial paralysis and assess the clinical efficacies of 3 kinds of EA waveforms (continuous wave, disperse-dense wave and intermittent wave). METHODS: One hundred and twenty-nine cases of Bell's palsy were randomly divided into a continuous wave group (45 cases), a disperse-dense wave group (40 cases) and an intermittent wave group (44 cases). The acupoints were Dicang (ST 4), Jiache (ST 6), Taiyang (EX-HN 5), Xiaguan (ST 7), Hegu (LI 4), etc. The House-Brackmann (H-B) scale was used in the assessment on the day of the inclusion, in the 1st, 2nd, 3rd and 4th sessions of treatment and in 1st and 3rd months of the follow-up visit after the end of treatment separately. RESULTS: The cured rates were 68.9% (31/45), 60.0% (24/40) and 65.9% (29/44) in the continuous wave group, the disperse-dense wave group and the intermittent wave group separately. The results of the rank sum test showed that the efficacy comparison among the groups did not present the statistically significant difference (P > 0.05). CONCLUSION: Electroacupuncture achieves the significant clinical efficacy on peripheral facial paralysis and there are no any significant differences in the efficacy among the different waveforms. It is suggested that the clinical efficacy of electroacupuncture on the disease has nothing significant correlation with the waveforms.

METHODS: The clinical and laboratory features and the treatment response, especially the safety profile of sorafenib in an acute monocytic leukemia patient with FLT-ITD were reported. RESULTS: The patient achieved clinical and molecular CR after sorafenib was added to the second course of combination chemotherapy. The side effects of sorafenib were mild and tolerable. CONCLUSION: The patient responded well to the combination of sorafenib and standard chemotherapy of AML without significant adverse effects.
