Objective To investigate the aberrant expression of phosphoproteome analysis of peripheral blood mononuclear cells( PBMCs) in patients with systemic lupus erythematosus( SLE) . Lay the foundation for further re-search of mechanism and treatment in patients with SLE. Methods Phosphopeptides were enriched using TiO2 from PBMCs of patients and healthy subjects, then analyzed by automated LC-MS/MS analysis. Phosphorylation sites were identified and quantitated by MASCOT and MaxQuant. Differential expressed proteins and peptides were screened based on the bioinformatics analysis. Results 1 035 phosphorylation sites were identified from SLE com-prared with normal subjects, 618 corresponding genes were screened out in annotation proteins. Pathway analyses showed 12 signaling pathways were identified. There were the most difference phosphorylation sites in mitogen acti-vated protein kinases( MAPK) signaling pathway. Conclusion Differently phosphorylated proteins and peptides can be detected in patients with SLE, which can be used as a mechanism of reference and supplement combined with metabolic pathway, and might be used as a potential target for treatment and research of SLE.

OBJECTIVE: To investigate inhibitory effects of jaridonin, a novel ent-kaurene diterpenoid compound isolated from Isodon rubescens, on human esophageal cancer cells growth in vitro and to understand the possible mechanisms. METHODS: After treatment for 48 h, the potential effect of jaridonin on the cell viability was examined using MTT assay. The effect of jaridonin on cytomorphology was observed by a fluorescence microscopy. The cell cycle distribution and the drop of mitochondrial membrane potential (ΔΦm) of EC-1 cells treated with jaridonin were analyzed by flow cytometry. Expressions of the p53, Bax, p21 and p27 proteins related with mitochondria apoptosis pathways were detected by Western blot. RESULTS: Jaridonin caused strong antiproliferative and apoptotic effects in HeLa, Spc-Al, HT-29, EC-1 cells. Compared with control, treatment with jaridonin induced G2/M phase cell cycle arrest and resulted in a up-regulation of p53. The expression of Bax and p21 as well as p27 is also up-regulated in EC-1 cells treated by jaridonin. Jaridonin promoted the release of cytochrome C from mitochondria to cytosol. The cleavage of caspase-3/9 in EC-1 cells was also observed. CONCLUSION: Jaridonin can significantly inhibit the growth of the cancer cells, and induce the apoptosis. The antitumor activity of jaridonin might be attributed partly to the induction of cell apoptosis through inducing cell cycle arrest and activating mitochondria pathway.

BACKGROUND: Myelin sheath related inhibitors have been found to have great impact on microenvironment of axon regeneration. Traditional Chinese medicine is gradual y becoming a research hotspot on improving microenvironment of nerve regeneration with its advantage on multiple factors and targets.
OBJECTIVE: To clarify the effect of Jisuikang on Nogo-66 receptor NgR expression after spinal cord injury.
METHODS: 144 rats were randomly divided into six groups: sham surgery group, model group, prednisone group, high-, moderate- and low-dose Jisuikang groups (n=24). Animal models of spinal cord injury were established by the modified Allen’s method in the later five groups. Rats in the prednisone group were daily given 0.06 g/kg prednisone acetate by lavage, once a day. Rats in the high-, moderate- and low-dose Jisuikang groups were daily intragastrically given 12.5, 25 and 50 g/kg Jisuikang, once a day. Rats in the sham surgery and model groups were intragastrically daily given 20 mL of saline, once a day. Rats in each group were administered drugs until death.
RESULTS AND CONCLUSION: Compared with the model group, NgR protein and mRNA expression levels were significantly lower in the prednisone, moderate-and low-dose Jisuikang groups. These data suggested that Jisuikang can improve the recovery of neurological function after spinal cord injury and effectively inhibit NgR protein expression at the site of injury so as to suppress the microenvironment factors harmful to nerve regeneration and further improve the microenvironment of nerve regeneration.

Objective To explore the new ways for treating multiple-ulcer treatment of breast tuberculosis. Methods The clinical data fo 10 cases of muhiple-ulcers summary of TB breast-conserving surgery and breast sur-gery purely traditional procedure were retrospectively analyzed. Results Surgical incision of 10 patients were healed stage Ⅰ, 2 patients experienced abscess drainage before admission to hospital and local incision healing was poor, who were healed through the out-patient dressing, and no skin ischemic necrosis occurred as well as the breast was in good shape. Follow-up lasted 3 to 26 months, during which period there was no recurrence, and patients and their families present with 100% satisfaction. Conclusion Conserving surgery with anti-TB rules is the new way of muhi-ple ulcer type of breast tuberculosis treatment,which is minimally invasive, effective, safe, with less complications and economical and practical advantages.

Objective To explore the effect of Jisuikang on neural functional recovery, and expression of brain-derived neurotrophic factor (BDNF) protein and mRNA level after spinal cord injury (SCI). Methods 144 female Sprague-Dawley rats, weighted 180 to 220 g, were used for experiment. 24 rats were randomly extracted into sham group (Group A), which had their vertebral plates and spines bitten away only.The others were randomly divided into model group (Group B), prednison group (Group C), and high, middle and low doses of Jisuikang group (Groups D to F) after SCI, 24 rats in each group. Group C was given 0.06 g/(kg ⋅ d) prednison, and Groups D to F were given 50, 25 and 12.5 g/(kg ⋅d) Jisuikang respectively, which were given 20 ml/(kg ⋅d) volume by intragastric administration. Groups A and B were given the same volume of normal saline (NS). The Basso-Beattie-Bresnahan (BBB) scores and oblique board test were applied to test the postoperative results 24 hours, 3, 7 and 14 days after SCI. The rats were executed and the spinal cord tissues were extracted 3, 7 and 14 days after SCI. Immunohistochemistry, Western blotting and RQ-PCR were applied to test the expression of protein and mRNA of BDNF. Results BBB scores and angle of oblique board test were significantly lower in Groups B to F than in Group A 24 hours after SCI (P<0.01). BBB scores were higher in both Groups C and E than in Group B 3 to 14 days after SCI (P<0.05), and was significantly higher in Group E than in the other groups 14 days after SCI (P<0.01). The results of immunohistochemistry and Western blotting showed that the protein expression of BDNF were significantly higher in Groups C and E than in Group B at different time points in the injured area after SCI (P<0.01), while there was no significant difference between Groups C and E (P>0.05). The results of RQ-PCR showed that prednisone and Jisuikang promoted the expression of BDNF mRNA. Group C (prednisone) had a most obvious effect at the beginning while Group E was better than Group C 14 days after SCI. Conclusion Jisuikang can promote the neural functional recovery and the expression of BDNF on both protein and mRNA level in SCI rats.

OBJECTIVETo improve the method for monitoring sleep state and respiratory rhythm of SD rats, providing a solution for rats' chewing on the wires, signal loss and instability problems in the animal model of sleep apnea syndrome (SAS).

METHODSWe improved monitoring electrodes of both electrocorticogram (ECoG) and electromyogram (EMG), signal circuit and animal operation.

RESULTSOperation time was shortened and wound exposure time was reduced, which made it easier for postoperative recovery. The ECoG and EMG signals were more stable with sharp image, and signal circuit lines had better conductivity and material durability, achieving continuous monitoring for a long time and high success rate. We could precisely distinguish the sleep wake state and the sleep apnea events in rats according to these signals.

CONCLUSIONThe improved method is more reliable and practical to test the small animal model of SAS, and is more easily to operate and the signals are more stable.
