Objective To observe the ultrastructural changes of Candida albicans by the effect of oyster antibiosis protein which was extracted from muscle of oyster.Methods The colonies of candida albicans exposed to oyster antibiosis protein for 24 hours,with a blank control group and the differences of their ultrastructure were studied under electron microscope.Results After affected by oyster antibiosis protein for 4h,the cell walls were lacked and had reductus with pyknotic cytoplasm.16 hours later,most cells became global shape and their cytomatrix components were lost and some vacuoles appeared in the cytoplasm.24 hours later,the cell walls depleted and the cells spitted.Conclusion oyster antibiosis protein affected commendably the function of candida albicans.

Objective To analyse the effects of high insulin on the expression and function of P-glycoprotein (P-gp), and preliminarily investigate the influence of insulin on chemotherapeutic sensitivity in MCF-7/ADR cells. Methods MCF-7/ADR cells were cultured with different concentrations of insulin(0.001, 0.005, 0.01, 0.05 and 0.1μmol/L). Real-time PCR was used to detect the expression of P-gp mRNA. Western blot assay was used to detect the expression level of P-gp. Rhodamine 123 was used to detect the efflux function level of P-gp. Cell viability and chemotherapeutic sensitivity were detected by MTT assay. Results High concentration of insulin (0.1 μmol/L) promoted the proliferation of MCF-7/ADR cells. The concentration of insulin (0.05 and 0.1 μmol/L) accelerated P-gp mRNA and protein expression, which also augmented the efflux function of P-glycoprotein and reduced the chemotherapeutic sensitivity to epirubicin. Conclusion High concentration of insulin may influence the drug resistance of breast cancer cells by promoting the expression and function of P-glycoprotein of MCF-7/ADR cells.

Objective To analyze the imaging features and its value in diagnosing primary malignant fibrous histiocytoma(MFH) of bone.Methods Imaging features(X-ray,CT,MRI) in 8 cases of MFH confirmed pathologically,and were retrospectively reviewed.Results The location of lesions in 6 cases was in upper femur,2 cases was in upper tibilar.Worm-eaten-like bone destruction withindistinct margin was presented on X-ray film,some lesions showed slightly marginal sclerosis.Tumors were soft tissue density on CT(CT value was 34~35 HU).The masses of soft tissue were showed much distinct.Conclusion The primary MFH of bone is not of characteristic imaging findings.It can improve obviously the diagnosis of the disease by the comprehensive analysis of the imaging data.

AIM:To explore the differences between unilateral recess-resection (R & R) and bilateral lateral rectus recession (BLR-rec) in the treatment of basic intermittent exotropia.METHODS: A retrospective analysis of treatment of basic intermittent exotropia in 89 patients,in which 49 cases underwent unilateral recess-resection,40 cases underwent bilateral lateral rectus recession of external rectus retroperitoneal surgery January 2013 to January 2015 in our hospital.The stereopsis and strabismus were observed in 1d,1,6mo,1 and 2a after operation.RESULTS: There was no significant difference in the success rate and oblique degree between the two groups after 1d,1,6mo,1 and 2a (all P>0.05),but the success rate of the operation was reducing as time passed.After 2d of the operation,the drift of the R & R group was 12.10±5.74PD and the drift of the BLR-rec group was 7.78±4.21PD,the difference was statistically significant (P=0.021).The R & R group was more likely to cause lateral slanting than BLR-rec group.Two groups of patients with nearly stereopsis were both significantly improved,there was no significant difference between the two groups in the two groups (x2=4.530,P=0.210).CONCLUSION: The long-term stability of BLR-rec is superior to R & R.

Objective To investigate biomechanical analysis of poly DL-lactic acid (PDLLA)biodegradable fusion cage of the lumbar vertebrae in vivo degradation. Methods Forty-eight healthy adult porcine were divided into experimental group and control group at randomly. PDLLA cage full of autogenous bone and bone block with the same size were planted in L45 intervertebrae respectively. At the 1st, 3rd, 6th,9th, 12th, and 18th month postoperatively, the animals were sacrificed and the surgical spinal segment was observed. The range of motion (ROM) was measured. Results The ROMs had no statistical differences at all motion directions between the two froups at the 1st month postoperatively. But the ROMs of experimental group were greater than those of control group at extension direction at the 3rd and 6th month postoperatively. The ROMs of extension was the greatest while the ROMs of right rotation was the least in both groups. At the 9th month postoperatively: the ROMs of experimental group greater than those of control group except at rotation. The ROMs of right rotation was the least in both groups. The greatest ROMs was at extension in experimental group and at right bending in control group. ALL ROMs tended to decrease and the ROMs of extension had comparability between tow groups. At the 12th month postoperatively, experimental group had greater ROMs at extension and left bending and less ROMs at other directions. Likewise statistical differences showed only at extension. 18th month postoperatively all ROMs were close between two groups. Conclusion After PDLLA cage is planted, the first 3 months is autologous stable stage. The period of 3rd to 6th months is easily released stage. The operative segments are stable from 9th to 12th months and acquired.Critical period between stability and instability is from 6th to 9th months. Bone fusion is from 12th to 18th months postoperatively.

BACKGROUND:Posterior lumbar interbody fusion is a typical therapeutic method of lumbar degenerative disease. Present studies suggested that adjacent segment degeneration occurs after fusion. Recently, more and more scholars paid attention to the development of non-fusion of the spine. ＜br> OBJECTIVE:To compare clinical effects of Dynesys dynamic stabilization system fixation and posterior lumbar interbody fusion in treatment of lumbar degenerative disease. ＜br> METHODS:From July 2009 to July 2011, clinical data of 56 patients with lumbar degenerative disease were retrospectively analyzed. There were 28 cases of Dynesys dynamic stabilization system fixation, and 28 cases of posterior lumbar interbody fusion. Operation time, bleeding volume, and postoperative hospitalization time were compared in both groups. Visual analog scale was used to assess pain. Oswestry disability index was utilized to evaluate clinical effects. ＜br> RESULTS AND CONCLUSION:A total of 56 patients were fol owed up for 18-24 months. Visual analog scale and Oswestry disability index scores were significantly improved at 12 months after treatment in both groups (P＜0.01). Significant differences in operation time, bleeding volume, and postoperative hospitalization time were detected between both groups (P＜0.01). Dynesys dynamic stabilization system group was better than posterior lumbar interbody fusion group. Range of motion was better in the Dynesys dynamic stabilization system group than in the posterior lumbar interbody fusion group (P＜0.01). During fol ow-up, nail rope system and polyester sleeve loose were not detectable in the Dynesys dynamic stabilization system group. These results verified that compared with posterior lumbar interbody fusion, Dynesys dynamic stabilization system for lumbar degenerative diseases has a high safety and smal trauma, and can keep advantages of a fixed segment, and exert a certain effect on degeneration of intervertebral disc in the adjacent segment.
