Objective To establish the model of amyotrophic lateral sclerosis (ALS) with selective motor neuron disorder by organotypic spinal cord cultures, and analyze the role of astrocyte in the pathagenisis of ALS.Methods Organotypic spinal cord cultures were prepared using lumbar spinal cord slices from 8-day-old SD rat pups. The threohydroxyaspartate (THA) was applied into culture medium to establish ALS organotypic spinal cord cultures model. Motor neurons survival was evaluated by monoclonal SMI-32 immunohistochemical staining and glial fibrillary acidic protein staining to show astrocyte survival.Results Compared with the control group, there was significantly astrogliosis in the anterior horn and surrounding white matter in THA 100 μmol/L group, and the level of gliosis was increased followed the elongation of THA interference time. With the increasing of the number of astrocyte, the morphology of astrocyte was changed.Conclusion There is significantly astrogliosis in the anterior horn and the time of astrogliosis is markedly earlier than the time of motor neuron loss in the ALS model intervented with THA.

The chemical consitituents from cytotoxic fraction of the Callicarpa nudiflora extract were isolated and purified by a combination of HP-20 macroporous resin, silica gel and Sephadex LH-20 column chromatographies. The structures were elucidated on the basis of the spectroscopic data and comparison of their spectroscopic data with reported data. The cytotoxicity was evaluated by the MTT assay. The 50% and 70% EtOH elutions of EtOH-extract showed significant cytotoxic activities, leading to the isolation of twelve compounds, which were identified as luteoloside(1), lutedin-4'-O-β-D-glucoside(2), 6-hydroxyluteolin-7-O-β-glucoside(3), lutedin-7-O-neohesperidoside(4), rhoifolin (5), luteolin-7, 4'-di-O-glucoside (6), forsythoside B (7), acteoside (8), alyssonoside (9), catalpol(10), nudifloside(11), and leonuride(12). Compounds 3-6, 10 and 12 were isolated from this genus for the first time, and compound 9 was isolated from this plant for the first time. The cytotoxicity assay demonstrated that flavonoids 1-6, in various concentrations, showed monolithic proliferation inhibitory activities against Hela, A549 and MCF-7 cell lines. Compounds 3, 5 and iridoid glycoside 11 possessed higher cytotoxicacivities. In short, flavonoids are the main components of cytotoxic extract from C. nudiflora, while phenylethanoid glycosides are the predominant ingredient but inactive to cancer cell lines. In addition, the minor iridoid glycoside expressed weak cytotoxic activity.

OBJECTIVETo evaluate the efficacy and safety of Jinying Capsule (JC) in treating pelvic inflammatory disease patients with accumulated damp-heat syndrome (ADHS).
METHODSTotally 328 patients were recruited in a prospective, positive drug parallel controlled, and multi-center clinical trial. Of them 213 patients in the treatment group took JC (0.5 g per capsule), 4 capsules each time, 3 times per day, while 115 patients in the control group took Kangfuyan Capsule (KC, 0.4 g per capsule), 3 capsules each time, twice per day. The course of treatment was 4 weeks for all. Scores of Chinese medical syndromes, visual analogue scale (VAS) of the lower abdominal pain, and European quality of life-five dimension scale (EQ-5D) were observed before treatment and after 4 weeks of treatment.
RESULTSThere were 204 patients in the treatment group and 109 in the control group who completed this trial. The total effective rate of Chinese medical syndrome was 89.71% (183/204 cases) in the treatment group and 76.15% (83/109 cases) in the control group (P < 0.01). Compared with before treatment in the same group, EQ-5D scores increased, and VAS scores of the lower abdominal pain decreased in the two groups after treatment. EQ-5D scores was 0.857 ± 0.157 in the treatment group, obviously higher than that in the control group (0.753 ± 0.126, P < 0.05). VAS scores of the lower abdominal pain was 2.14 ± 1.23 in the treatment group, lower than that in the control group (2.33 ± 1.24), but with no statistical difference between the two groups (P > 0.05). No adverse reaction occurred in the two groups.
CONCLUSIONJC was superior to KC in improving Chinese medical syndrome and quality of life of pelvic inflammatory disease patients with accumulated damp-heat syndrome.
