AIM: To explore the mechanism and significance of the intestinal epithelial cellular membrane damage following burn serum. METHODS: The intestinal epithelial cell(IEC-6) were cultured. The changes of total membranous phospholipid contents fluidity of the IEC membrane were dynamically examined with fluorescence polarization technique and HPCE. RESULTS: In the early stage after stimulation by 20% burn serum, the membranous fluidity obviously decreased. The total phospholipid contents decreased, the content of PLA 2 markedly increased. CONCLUSION: The serial changes in IEC after burned could result in the damages of IEC membrane structure, the integrity of cell membrane and function.

Objective To explore the mechanism of intestinal epithelial cell membrane injury due to Pseudomonas aeruginosa adhesion. Methods The intestinal epithelial cells were cultured and adhered with Pseudomonas aeruginosa . The changes in the viability of the cells and the activity of membranous PLA 2, the calcium content of cell, contents of phospholipid and membrane fluidity were observed. Results At 3rd h after the adhesion of Pseudomonas aeruginosa , the viability of the intestinal epithelial cells decreased significantly, but the activity of membranous PLA 2, the calcium content of cell increased significantly; the contents of phospholipid(PL), phosphatidylinositol(PI) and phosphatidylcholine(PC) in cell membrane decreased gradually, but the membrane fluorescence polarization and microviscosity of intestinal epithelial cell membrane increased significantly. Conclusion The activation of PLA 2 and the degradation of phospholipid due to the overloading of calcium in intestinal epithelial cells after the adhesion of Pseudomonas aeruginosa to intestinal epithelial cells might be the fundamental factors to result in the reduction of membrane fluidity.

OBJECTIVETo explore the clinical effects of Mobi-C cervical artificial disc replacement (CADR) and anterior cervical decompression and fusion (ACDF) in treating single cervical disc herniation.

METHODSFrom June 2009 to June 2012, the clinical data of 27 patients with single cervical disc herniation were retrospectively analyzed. There were 18 males and 9 females, aged from 30 to 62 years old with an average of 46.7 years. Of them, 12 patients were treated with CADR (CADR group) and 15 patients with ACDF (ACDF group). All patients had pain and numbness in neck, shoulder and upper limbs, and courses of disease was from 1 to 13 months with an average of 2.4 months. The data of clinical evaluation and questionnaire survey about quality of life were collected before operation, postoperative at 1 week and final follow-up. Odom criterion was used to evaluate postoperative effect. Visual analogue scale (VAS) was used to record pain levels. Neck disability index (NDI) and health questionnaire SF-36 were used to assess the quality of life.

RESULTSNo complications about nerve and blood vessel were found and the patients were followed up from 6 to 30 months, with an average of 16 months. One week after operation, 10 cases got excellent results and 2 good in CADR group; 5 cases got excellent results and 10 good in ACDF group; there was significant difference between two groups (P<0.05). At final follow-up, 10 cases got excellent results and 2 good in CADR group; 12 cases got excellent results and 3 good in ACDF group; there was no significant difference between two groups (P> 0.05). Pain of upper limbs had obviously relieved between two groups at 1 week after operation and final follow-up (P<0.05). VAS of neck and NDI in CADR group had decreased respectively from preoperative 3.58±0.79, 23.42±6.36 to 0.58±0.51, 5.42±1.68 at 1 week after operation (P<0.05); but the index in ACDF group was no obvious at 1 week after operation. At final follow-up, VAS of neck and NDI and SF-36 score were obviously improved than preoperation (P<0.05) between two groups.
