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 enhance the ability of organizing, commanding, decision-making and contingency-meeting of campaign medical support commanding officers so as to qualify them for their positions by simulation training. Methods: Based on the decision support theory, modern medical support theory, health service optimized decision support system and medical support command simulation training system, we designed and constructed a simulation training platform for medical support decision optimization. Results: A network-based simulation training platform was successfully constructed, which gives a strong support to the simulation training in medical support decision optimization under the network circumstance. Conclusion: The application of the simulation training platform has enriched the content and renewed the pattern of training in decision optimization for campaign medical support commanding officers.

Objective To report the clinical and pathological features of the sensory neuropathy caused by a combined therapy of telbivudine and pegylated interferon α-2a in 2 patients with hepatitis B virus infection Methods Two male patients aged 48(case 1)and 20(case 2),who suffered from hepatitis B virus infection.were given telbivudine and pegylated interferon α-2a.After 4 months treatment,both patients developed numbness and pain in the lower limbs.The physical examination showed decreased pain sensation in distal extremities.Hypahidrosis appeared in distal extremities.The nails were pale changed in fingers and toes in cage 1.Case 2 presented mild weakness in the proximal muscle of lower limbs and the tendon reflex was decreased in both lower limbs.His 8erunl creatine kinase level was mild elevated.The electromyography examination and sural nerve biopsies were performed on both patients.Results Electromyography examination showed significant decrease of amplitude of sensory nerve action potentials and mild decrease of sensory nerve conduction velocities in both patients.The amplitude of motor nerve action potentials was also decreased in case 2.Light microscope examination revealed middle reduction of myelinated fibers,wallerian degeneration of myelinated fibers and small clusbers of regenerated fibers in sural nerve.Electro microscopy examination revealed the loss of unmyehnated nerve fibers.After the combined therapy was stopped and vitamin B,CoQ10 and L-camitine were administered,the patients recovered gradually.Conclusions Combined therapy of telbivudine and pegylated interferon α-2a may cause sensory neuropathy with electrophsiological and pathological abnormalities of axonal lesions.The sensory neuropathy induced by the combined therapy may be reversible.

AIM: To establish the quality standard for Guishao Soft Capsules(Radix Paeoniae Alba,Radix Angelicae Sinensis,Rhizoma Chuanxiong, etc.) METHODS: Radix Paeoniae Alba,Rhizoma Atractylodis,Rhizoma Chuanxiong,Rhizoma Alismatis and Radix Angelicae Sinensis were identified by TLC.The contents of albiflorin and paeoniflorin in Guishao Soft Capsules were determined by HPLC.HPLC analytical method was carried out(using) a C_(18) column and a mixture containing 17 volume of acetonitrile and 83 volume of 0.05% acetic acid as the mobile phase.The detection wavelength was set at 230 nm. RESULTS: Spots obtained from the test solutions had the same color in reference solution and medical material in the same location,and the blank solution had no interfernece.The linear range of albiflorin was from 0.53 ?g to 1.06 ?g(r=0.999 8),the average recovery was(100.3%.) The linear range of paeoniflorin was from 0.29 ?g to 2.00 ?g(r=0.999 9),the average recovery was(99.49%.) CONCLUSION: In TLC,the spots are very clear and specific to identify the herbal medicine in Guishao Soft Capsules.It is simple,quick,high precise and accurate for HPLC to control the quality of Guishao Soft Capsules.

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 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.

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.
