Asymmetric dimethylarginine(ADMA)is a natural L-arginine analogue that reduces the bioavailability of nitric oxide in plasma and various types of tissues,acting as an endogenous NO synthase inhibitor in vivo.ADMA is considered a common pathway mediating the adverse vascular effects of traditional and nontraditional risk factors.These preclinical findings are thought to be of major importance as ADMA predicts cardiovascular events and mortality in patients with chronic kidney disease(CKD).Also,ADMA uniformly predicts the progression of moderate and severe CKD.The present study summarizes the latest developments in this field.

Objective To compare the antineoplastic immunological effects of nanoemulsion-encapsulated MAGE1-HSP70 and SEA(the ratio of MAGE1-HSP70 fusion protein to SEA superantigen was 100∶1)as NE(MHS)vaccine as given in different routes,and try to look for a novel and effective immune route.Methods NE(MHS)was prepared using magnetic ultrasound methods,and the size,the encapsulation rate and the stability of the nanoemulsion vaccine were evaluated.C57BL/6 mice were immunized via p.o.,subcut.,i.v.,or i.p.route.The cellular immunocompetence was detected by ELISpot assay and LDH release assay.The therapeutic and tumor challenge assay were examined too.Results When the vaccine was given orally,the tumor masses formed 28 days after B16-MAGE1 inoculation in mice were markedly bigger than that formed in the mice of the other groups(P

Objective To report on an autosomal recessive pyramidal tract, corpus callosum and peripheral nerve degeneration in a family and to study its relationship with other complicated hereditary spastic paraparesis. Methods Neurological examination revealed the following findings. Proband was a 20 year old man who spoke slowly and developed mental retardation in his childhood. Gait disturbance with pyramidal signs and mild cerebellar ataxia were found when the patient was 16. Slight sensory disturbance was present in the lower extremities. His 23 year old sister had similar symptoms at beginning of disease when she was 17. Their clinical courses were bad progressively. Electromyogram showed nerve conduction velocity decrease in the nerve medianus and neurogenic process in the muscle tibialis anterior. Cranial MRI, muscle and nerve suralis biopsies were examined in proband patients. Results MRI showed thin corpus callosum with cerebral and cerebellar atrophy as well as enlargement of ventricle system. Myopathological findings were characterized by angular atrophy fibers in small groups with appearance of hypertrophy fibers. The nerve suralis biopsy showed degeneration and regeneration of myelinated axons. Conclusion Our study confirms that this family is hereditary spastic paraparesis with mental retardation, thin corpus callosum and polyneuropathy reported mostly in Japan. Axonal polyneuropathy is a common pathological feature of this disease.

[Objective]To modify posterior lumbar interbody fusion for improvement of convenient manipulation and safety in the operation,and solid fusion. [Methods]After total decompression of the spinal nerve through posterior medline approach,discectomy of the slipping segment was performed with a circular saw with diameter of 1.0 centmeter.Under direct visualization through the hole of the circular saw,the disc tissue including cartilage of upper and lower end plates was removed with a long handle curette.After pedicle screw and rod system was placed,a bone block harvested from the posterosuperior iliac with a circular saw with diameter of 1.2 centmeter was implanted into the intervertebral space.Then compression of the intervertebral space to catch the bone lock firmly was conducted by regulating and fixing the the pedicle screw and rod system.[Results]Forty-eight patients in this report were followed up from 6 to 24 months.Based on JOA low back pain score,there were 36 patients was in excellent result,8 in good and 4 in fair,the satisfactory rate was 91.67% and effective rate was 100%.[Conclusion]Using circular saws in posterior lumbar interbody fusion has advantagas of good visualization profit removing disc tissue,preventing neurovascular injuries,and making good bone grafting bed.Convenient and secure bone harvesting decrease blood loss,time consume during the operation and prevent donor site complication.Futhermore,follow up results of the patients in this report demonstrate that posterior interbody fusion with circular saw for treatment of lumbar spondylolisthesis have satisfactory outcome and high fusion rate.

Objective To explore the technique outcome of fixing the ventral stress pedicle screws into the injured vertebrae, as a method to enhance the posterior internal fixation. Methods From March 2002 to March 2005, 33 single thoracolumbar fractures were studied retrospectively. Among which, 16 cases were treated with the above method(group A), and the other 17 were treated with traditional two-level fixation(group B). Group A involved 11 males and 5 females, aged 48 years averagely(range, 32-74 years); and group B included 12 males and 5 females, aged from 21 to 61 years(mean, 40 years). All the patients underwent the operation within up to 3 weeks after fracture. For the injured vertebral bodies, their pedicles were intact on either unilateral or bilateral side, and their lower half and endplate were free from split. In group A, the pedicle screws in the injured vertebrae were used to achieve the ventral press vertical to the distraction for the stress neutralization, and also with the routine distraction and lordosis restoration, simultaneously. The mean follow-up period was 11 months with a range from 6 to 24 months. Results After operation, the optimal Cobb angle and anterior column restoration were achieved through the ventral reduction from the injured vertebral body, which was the contribution from the vertical stress pedicle screw. The degree in anterior movement of injured vertebrae pre- and postoperatively was much more in group A than group B, and the difference was of statistical significance(P

The influences of propylene glycol mannate sulfate (PGMS) on experimental thrombosis and thrombolysis in vivo were studies after iv 8. 125, 6. 25, 12. 5 , 25mg/Kg in rabbits, and the effect of antithrombosis of PGMS was compared with that of heparin. The results showed that PGMS possessed remarkable effect of antithrombosis. In order to explore the mechanism of antithrombosis of PGMS, we studied the influences on the fibrinolytic and coagulant function of rabbits. The results showed that PGMS can pronouncedly prolong the prothrombin time (PT), thrombin time (TT), kaolin partial thromboplastin time (KPTT), and enhance the activity of antithrombin-III (AT -III). PGMS can cause a remarkable increase in fibrin degradation product (FDP) , shorten euglobulin lysis time (ELT) , and a decrease in the contents of fibrinogen and plasminogen activity. These results suggested that PGMS probably exert the antithrombotic effect by inhibiting coagulation and activating fibrinolysis.
