Lysyal oxidase (LOX),a cooper dependent monoamine oxidase,can stabilize the extracellular matrix and is closely related to the tumor cell differentiation,vicious transformation and invasiveness.LOX is secreted into extracellular,and it is resolved into a small fragment by sol protease,which is lysyal oxidase propeptide (LOX-PP).According to research,LOX-PP has its own structure and physiological functions,which can inhibit the growth of tumor cells.LOX-PP also plays a significant role in the generation and progression of tumor,which is likely to be a new therapeutic target.

The precise measurement in lens thickness in vivo, provides great application value for intraocular accommodation and ametropia development mechanism research.And it has great clinical significance for the diagnosis and treatment of glaucoma and cataract.Currently, many ultrasonic methods and optical methods are used in measuring lens thickness.The measurement principles, advantages, disadvantages and the accuracy of the instruments are summarized in this paper.Among these methods, Orbscan II, Pentacam, Lenstar and AS-OCT can be used to measure lens thickness instead of A-scan.More important is the fact that UL-OCT can dynamically monitor the change of the lens thickness with intraocular accommodation.Choosing an instrument with higher measuring accuracy to examine the lens thickness, can provide more accurate and convincing lens thickness data for clinical and scientific research.

Objective:To investigate the activated state of TH1/TH2 cytokines and T lymphocytes and to explore the pathogenesis of ankylosing sondylitis.Methods:Cytokine levels of Th1(IFN-?、TNF-?、IL-2)and Th2(IL-10、IL-5、IL-4) in plasma, percentages of CD3 +、CD4 +、CD8 + T cells、B cells(CD19 +) NK cells(CD16 +56 +)and CD3 +HLA-DR +、CD4 +HLA-DR +、CD8 +HLA-DR + T cells in peripheral blood lymphocytes were detected by Flow Cytometry.Results:In patients with AS ,plasma levels of TNF-?、IL-2 were significantly lower than that of healthy controls. IL-10 were significantly higher than that of healthy controls. In AS patients, percentages of CD3 +and CD8 + T cell from peripheral blood lymphocytes were significantly lower than that of healthy controls. Percentages of CD8 +HLA-DR + T cell were significantly lower than that of healthy controls. CD4 +HLA-DR +T cell was significantly highter than that of healthy controls.Conclusion:In patients with AS , lower levels of TNF-?、 IL-2 and higher level IL-10 at plasma indicate an inclination between TH1 and TH2, such as an impaired TH1 cytokine profile and an activated TH2 cytokine profile, especially in TNF-?.

OBJECTIVETo investigate the causes and managements of postoperative neurological complications in pedicle screw internal fixation for the treatment of degenerative scoliosis (DS).

METHODSThe data of 325 patients with degenerative scoliosis underwent pedicle screw internal fixation was retrospectively analyzed from February 2000 to April 2013. There were 22 patients with postoperative neurological complications. Of them, 16 cases complicated with numbness or pain of lower limb and 6 cases with obvious sensation and motor function decreasing in lower limb. The patients were treated with trophic nerve, dehydration, glucocorticoids, reoperation according to the causes of disease. Postoperative at 3, 6 months and 1 year later, according to VAS scoring and muscule power improvement,the recovery of nerve injury was assessed.

RESULTSPostoperative at 3,6 months and 1 year later,VAS scoring of 16 patients with slightly nerve injury was 2.81 +/- 0.66, 1.94 +/- 0.77, 0.63 +/- 0.62, respectively, and the symptoms had obviously improved than 1 week after operation (P < 0.05). Postoperative at 3 months, among 6 patients with severe nerve injury,muscule power improved in 2 cases and no-improved in 4 cases, with VAS scoring of 4.83 +/- 1.17; postoperative at 6 months,muscule power still had not improved in 3 cases,with VAS scoring of 4.17 +/- 0.75; both of the VAS scoring had not significant difference than 1 week after operation (P > 0.05). One year later, there was no muscule power improvement in 2 cases,with VAS scoring of 3.00 +/- 1.26, there was significant difference than 1 week after operation (P < 0.05).

CONCLUSIONThe causes of postoperative neurological complication in internal fixation for the treatment of dengenerative scoliosis includes: dragging and torsion injury of spinal marrow and nerve root because of excessive orthopedic of scoliosis; inderect injury of nerve root because of malposition of pedicle screw; nerve functional impairment caused by spinal cord ischemia. Avoiding the above factors could decrease the complication and early discovery and treatment could decrease the adverse outcomes.

Objective To summarize the characteristics of ecthyma gangrenosum and explore its significance in early diagnosis of pseudomonas aeruginosa sepsis in children.Methods We retrospectively reviewed the medical records of 11 children with ecthyma gangrenosum who were hospitalized at Guangzhou women and children's medical center between May 2008 and Apr 2011.Results Eight cases were male and 7 were less than twelve months,the oldest was 2 years old,all of them were diagnosed as Pseudomonas aeruginosa spesis.Two patients had a single lesion,and the others had multiple lesions.Ecthyma gangrenosum located on the trunks in 7 cases,on anogenital areas in 5 cases,on extremities in 5 cases and on faces in 3.The lesions appeared on day 2 to day 10.On average,they developed on day 5.Seven patients developed ecthyma gangrenosum before admission,the course of the illness before admission was 6 days.Fever and multiple organ dysfunction occurred in all the patients and their cultures grew pseudomonas aeruginosa,blood cultures were positive in 8 cases,the others were isolated psudomonas aeruginosa from tissue of the lesion,discharge,ascites,pleural effusion,respectively.The time of ecthyma gangrenosum appeared was earlier than the time of the culture results reported.All of the patients were started empiric antibiotics therapy on admission,the initial antibiotic regimen was appropriate in 9 patients,8 needed surgical intervention,4 were treated with continuous blood purification.Ten patients survived and 2 died,the hospital stay was from 1 to 63 days,the average was 30.Conclusion Ecthyma gangrenosum is a known cutaneous manifestation of pseudomonas aeruginosa sepsis,which is helpful for early diagnosis and treatment,and then the outcome will be improved.

Objective To study the influence of early intensive blood pressure (BP) lowering treatment on peri-he?matomal secondary neuronal injury and prognosis after acute intracerebral hemorrhage. Methods A randomised con?trolled trial consisting of 36 consecutive patients within 6 h of intracerebral hemorrhage onset were randomly assigned to intensive BP lowering group and guideline BP lowering group. All patients underwent MR spectroscopy at 72 h and were followed up 90 days. N Acetyl Aspartate/Creatine (NAA/Cr) and lactic acid wave around peri-hematomal at 72 h, neuro?logic function at early stage, and death and/or disability at 90d were compared between these two group. Results Spec?trum lines were obtained from thirty-one patients:14 from intensive BP lowing group and 17 from guideline BP lowering group. There was no significant difference in the percentage declines of NAA/Cr at 72 h between the two groups (13.3%± 4.2% vs. 11.9%± 2.8%, P = 0.308). There was no statistical differences either in neurologic function at 7 d or in death and/or disability at 90 d (P>0.05). Conclusions Early intensive BP-lowering treatment had no role on peri-hematomal secondary neuronal injury and prognosis after acute intracerebral hemorrhage. Further high-quality and large-scale ran?domised controlled trial are necessary to verify this result.
