OBJECTIVE Recent studies have demonstrated that the Nlrp3 inflammasome serve as a central role in the pathogenesis of cardiovascular diseases and endothelial dysfunction occurs in association with several cardiovascular risk factors. Given the demonstrated anti-inflammatory effects of aspirin, the present study was designed to test whether aspirin diminish NLRP3 inflammasome activation and prevent endothelium injury and associated coronary artery damage during LPS. METHODS Mouse carotid arterial endothelial cells (CAECs) were cultured and treated with 0.1-3 mmol·L-1 of aspirin in response to LPS (2 μg·mL-1) stimuli. After 24 h, the Nlrp3 inflammasome complexes consist of varied proteins were analyzed by WB. NO and T-AOC in the supernatant was detected by ELISA. Intracellular reactive oxygen species (ROS) generation for 24 h was observed by DCF fluorescence. The mice were treated with aspirin (12.5 mg·kg-1 per day, 62.5 mg·kg-1 per day, 125 mg·kg-1 per day) and dexametha?sone (0.0182 mg · kg- 1 per day) for 7 d. The level of IL- 1β,IL- 18 protein was detected by ELISA. RESULTS Immunofluorescence results showed the colocalization of Nlrp3 with ASC or caspase 1 decrease in a concentration- dependent manner. Meanwhile, the expression of Nlrp3 and caspase 1 protein was decreased with the concentration of aspirin, but no changes the expression of ASC protein. Nlrp3 protein levels in CAECs were 0.33- 0.8- fold and cle- caspase 1 protein levels in CAECs were 0.48-1-fold compared to those in LPS stimulation when treated with 0.1-3 mmol·L-1 aspirin for 24 h (P<0.01). Aspirin significantly antagonized the effect of LPS on NO (1.22-1.91-fold that of LPS stimulation, P<0.01) and T-AOC expression (1.02-1.90-fold that of LPS stimulation, P<0.01). As the different concentration of aspirin treated, the generation of ROS was 0.51-1.10-fold that of LPS stimulation (P<0.01). In vivo data shown the level of IL-1β, IL-18 protein from serum are in concordance with the level of Nlrp3 inflammasome activation. CONCLUSION We conclude that aspirin has anti- inflammatory properties, protecting CAECs from LPS-induced injury by inhibition of NLRP3 inflammasome activation through ROS pathway.

Objective To evaluate the clinical diagnostic value of nucleic acid amplification (TB- RNA),bacteriophage-based assay,3D culture and smear on the detection of Mycobacteria tuberculosis.Methods 291 clinical sample including 110 sputum,54 thoracic fluid,37 throat swab,31 bronchial fluid,13 cerebrospinal fluid,12 urine,8 lymph fluid and 20 others (pericardial effusion,feces, blood and abdominal fluid) and gynecological specimen (including 6 leucorrhoea and menstrual blood) were analyzed by these four methods.Results Among the 291 clinical samples,the positive rate of mycobacteria tuberculosis for TB-RNA,bacteriophage-based assay,3D culture and smear were 37.1%,28.9%,27.5% and 10.3%.The sensitivity and specificity of the TB-RNA,bacteriophage-based assay,3D culture and smear were 54.3% & 100%,41.7% & 88.9%,31.7% & 93.5% and 14.6% & 98.9%,respectively.Conclusions TB-RNA is an effective clinical diagnostic method for Mycobacteria tuberculosis.Although the sensitivity of smear is poorer than others,it is a universal testing method in clinical laboratory due to low cost.The positive rate of mycobacteria tuberculosis for 3D culture is lower than that of bacteriophage-based assay and TB-RNA.Although the time to result for 3D culture might last for few weeks,the isolates can be used for drug resistance screening and bacterial identification.

The NSP2 gene of porcine reproductive and respiratory syndrome virus (PRRSV)S1 strain was partly amplified and cloned into a prokaryotic expression vector pGEX-6P-1 and a fusion protein GST-tNSP2 with molecular weight of 50 kDa was expressed in E.coli. The purified GST-tNSP2 protein showed a strong reaction with the PRRSV-positive sera in Western blot assay. Balb/c mice were immunized with the purified protein, and the splenocytes of the immunized mice were fused with murine myeloma cells SP2/0. After subcloning by 3 times, two hybridoma clones which produced McAbs steadily were screened by ELISA, named 3H3 and 2B5. They all reacted strongly with the PRRSV S1 infected Marc-145 cells in IFA, but not with the PRRSV SY0608 strain. Both of the McAbs belong to IgG1 isotype, and their light chains belong ? type. The expressed GST-tNSP2 protein and McAbs could be used for identification of PRRSV isolates and functional analysis of NSP2.

Objective To investigate the axonal lesion in chronic inflammatory demyelinating polyneuropathy(CIDP).Methods Eighteen patients had undergone sural nerve biopsy.The clinical and electrophysiological distinction based on the different pathological changes were analyzed.Results Five patients with demyelination predominance which presented myelinated fiber with thin myelin.Three of them showed also mild axonal degeneration.Eight patients with axonal lesion predominance which presented Wallerian degeneration and regeneration of myelinated fibers.Three patients with mixed myelin and axon lesion of myelinated fibers and two with mild lesion.There was no significant difference between CIDP predominantly with axonal lesion and demyelination.Electrophysiological examination shows both axonal lesion and demyelination feature in some of the 2 types patients at the same time.Conclusions Axonal lesion is a common pathological change in CIDP and should not be considered as an exclusive criterion in diagnosis of the disease.Infiltration of macrophages is a common change.

Objective To evaluate the correlation between postoperative complications and prognosis after radical hepatic resection for colorectal liver metastasis (CRLM).Methods We retrospectively summarized patients' clinicopathological data and postoperative complications.Postoperative complications were graded using Dindo-Clavien system of classification.Then we investigate the relation between these data and prognosis.Results One hundred and seventy-three patients were recruited.Postoperative complications developed in 59 (34.1％) cases.37 patients had minor complications and 22 patients had major complications.On univariate (x2 =8.106,P =0.004) and multivariate analysis (x2 =8.006,P =0.005),complication was an independent predictor of overall survival (OS).However,in a subgroup of patients with minor compications,morbidity was not associated with a significant reduction in both OS (x2 =3.199,P =0.074) and disease-free survival (x2 =1.313,P =0.252).Conclusions Postoperative complications are an independent factor for long-term outcomes after hepatic resection for CRLM.
