This paper is to report the changes of the protein metabolism in the rat soleus muscle in vitro after 37% TBSA full-thickness burns covering one hindlimb and the effects of leucine and insulin on the burned muscle.It was found that there werea significant decreases of the protein content and marked exaggeration of the rates of tyrosine incorporation,tyrosine release and tyrosine net release in the burned muscle.No changes of the above-mentioned parameters could be revealed in the muscle of the unburned limb and the controls.Elevation of leucine concentration in the medium could not improve the protein metabolism of the burned muscle.0.1u/ml of insulin could significantly stimulate the tyrosine incorporation in the muscle of the unburned limb and the controls,but no similar effect was observed on the burned muscle.The results indicate that increased protein degradation of the local burned muscle is responsible for the postburn negative nitrogen balance;administration of leucine alone cannot improve the protein metabolism in the local burned muscle;and the sensivity of the burned muscle to insulin is suppressed.

Full thickness scalding of 37% TBSA was inflicted io rats. Three days later, the liver of the animals was isolated and the changes of the protein metabolism in the liver and the effects of insulin on the changes were evaluated.It was found that the protein and DMA levels of the liver showed no obvious changes after scalding, but the RNA content increased by 24% and the rate of leucine incorporation by 31%. After the addition of insulin, the leucine content increased by 23.% and 25.8% in the controls and the injured animals respectively. The results indicate that the rate of protein synthesis in the liver of the scalded animals increases, which is likely to be related to the increase of RNA content, and the liver protein synthesis remains to be sensitive to insulin.

Objective To evaluate gastric bypass on relieving type 2 diabetes mellitus. Methods From September 2009 to September 2010,Thirty two cases of type 2 diabetes mellitus patients underwent gastric bypass operation in Xijing Hospital.Preoperative FBG,2hPG,HbAlc,weight,blood pressure and fatty liver were compared with that on 1 month,6 months,12 months after operation. Result There was no significant postoperative complications.FBG on 1 month,6 months,12 months postop and preoperative level was respectively 7.8 ± 2.2,7.7 ± 2.2,7.2 ± 1.8 and 11.1 ± 2.7 ( mmol/L),P ＜ 0.05.2hPG was 10.2 ± 2.6,10.5±2.8,10.5 ±3.1 and 14.0 ±3.5 (mmoL/L),P＜0.05.HbAlc was 7.6％ ±1.4％,7.5％ ± 1.7％,7.1％ ±1.9％ and9.0％±2.3％,P＜0.05.FBG[(6.9±1.5) mmol/L],2hPG[(10.0±3.2) mmol/L] and HbAlc[ (6.9％ ± 1.9％ ) ] on 12 months after operation were lower than preoperative[ FBG ( 10.7 ± 2.9 ) mmol/L,2hPG ( 14.3 ± 4.1 ) mmol/L,HbAlc ( 8.8％ ± 2.0％ ) ] in patients with BMI ＜25 kg/m2 (P ＜ 0.05 ).In patients with preoperative BMI ≥ 25 kg/m2,FBG ( 7.5 ± 2.3 ) mmol/L,2hPG ( 11.3 ±2.9) mmol/L HbAlc (7.3％ ± 1.9％ ),12 mos pest were lower than that of preoperative levels of [FBG(11.7 ±2.3) mmol/L,2hPG(13.5 ±2.4) mmol/L,HbAlc(9.2％ ±2.7％)] (P ＜0.05).Postoperative blood pressure became normal in 5 out of 6 patients complicating preoperative high blood pressure as evaluated on 12 months after operation. Fatty liver ameliorated in 8 out of 17 patients.Conclusions Gastric bypass significantly improves glycometabolism and comorbidity in type 2 diabetes patients.

Objective To explore the mechanism of negative nitrogen balance in the treatment after burns. Methods The means of immuno precipitation deduction and ELISA were used to test the activities and contents of 26S proteasome and 19S regulator in skeletal muscle of rats inflicted with 30%TBSAⅢ burns. Results TNF? markedly raised the activities and contents of 26S proteasome and 19S regulator in skeletal muscle after scalding. Conclusion TNF? activates the 26S proteasome system in skeletal muscle, thus it enhances the degradation of protein, which is associated with the development of negative nitrogen balance following scalding.

Objective:To investigate the effect of methylphenidate on the ERP waveform of children with attention deficit hyperactivity disorder(ADHD) between responders and non-responders and it's psychological significance.Methods:ERP elicited by the continuous performance test were recorded before and under methylphenidate treatment in 28 ADHD children and their behavioral performance were collected simultaneously.Based on the behavioral results,the patients were divided into two groups:responders and non-responders.Results:After medcation,the responders' behavioral performance were significantly better,amplitude of NOGO-P3(30.24?10.78?v) were also larger than that of before treatment(20.34?11.42?v,P=0.04);No significant differences were found in the behavioral performance and NOGO-P3 amplitude before and after treatment(23.51?11.97?v/25.88?13.96?v,P=0.61) in the non-responders group.The amplitude of NOGO-N2 of the two groups did not have significant difference before and under methylphenidate treatment.Off medication,there were no differences between responders and non-responders.Conclusion:Methylphenidate can improve the ability of response inhibition in responders as well as increase the amplitude of NOGO-P3 of them.

Objective To study the effectrve approach of the nutrition support in burn patients. Methods The means of immuno-precipitation-deduction,ELISA and fluore-photometion were used to test the change of activities,protein expression of the 19S regulator and the rate of protein degradation in skeletal muscle in scard rats with enteral feeding or parenteral nutrition. Results Compared with parenteral nutrition , enteral feeding could markedly reduce the activity and protein expression of the 19S regulator ,and the digeneration of skeletal muscle was also lower. Conclusions The early enteral feeding can distinctly inhibit the system of 26S proteasome , thereby reduce the protein degradation of skeletal muscle in scald rats,which may be benefical to the metabolic modulation of the burned patients.

Objective To examine the curative effect of EEG biofeedback therapy on children with attention deficit hyperactivity disorder (ADHD),and to investigate the neural mechanism underlying the executive function in children with ADHD.Methods 42 children with ADHD participated a Go/Nogo task before and after the EEG biofeedback therapy which was consisted of 20 times of treatments.The curative effect was evaluated using the behavioral and electrophysiological indexes associated with the Go/Nogo processing in the experiment.Results Commission error significantly decreased after the therapy ( (2.95 ±2.22 ) vs (4.65 ±4.47),P＜0.05 ).Latencies of P2 ( (210.00 ± 27.54) ms vs ( 228.27 ± 34.17 ) ms) and N2 components ( ( 310.59 ± 45.82) ms vs (328.00 ± 42.27)ms) elicited by Go trials significantly exhibited shorter at the end of therapy.Additionally,the amplitude of N2 component elicited by Nogo trials exhibited significantly decreased after therapy ((0.23 ±3.79)μV vs (-1.84 ± 4.23 ) μV,P ＜ 0.05).Conclusion The EEG biofeedback therapy is effective in debasing the hyperactivity/impulsive behaviors and improving the ability of target detection,which may be beneficial to the attention ability and conflict detecting in children with ADHD.EEG biofeedback is an effective treatment to ADHD.

Objective To investigate the curative effect of biofeedback treatment on attention-deficit/hyperactivity disorder ( ADHD ) patients using integrated visual and auditory continuous performance test ( IVA-CPT).Methods 23 ADHD patients undertaked 20 times of EEG biofeedback treatment using VBFB-3000A facility.Their executive and attention quotients were measured before and after treatment by IVA-CPT.Results The pre-therapy full scale of response control and attention quotients of ADHD were 58.26 ± 32.9 and 54.43 ±34.01 respectively.After the therapy, all the quotients got improved (response control 99.3 ± 12.6, attention 84.1 ± 15.9 ) except for stamina and speed quotients both in visual and in auditory.Conclusion Shortterm EEG biofeedback treatment is one of effective methods for ADHD patients,especially for hyperactive cases.

Objective To investigate dynamic changes and clinical significance of the high-sensitive Creactive protein(hs-CRP) level in acute cerebral infarction patients with different etiological types.Methods 136 patients with acute cerebral infarction were recruited.These patients were classified into five subtypes based on Trial of Org 10172 in Acute Stroke Treatment(TOAST) criteria.Serum hs-CRP levels on the 1st,3rd,5th,7th,14th day after onset from patients and 42 healthy controls were measured with immunoturbidimetry.The neurologic impairmentscore was determined with NIHSS.Results Serum hs-CRP levels is higher on the 1th,3rd,5th,7th,14th day than that of the control group ( (4.26 ± 1.31 ),( 12.57 ± 6.29 ),( 10.23 ± 4.49 ),(7.54 ± 2.33 ),(4.25 ± 1.77) mg/Land (2.56 ± 0.86) mg/L,t = 7.89,10.26,10.99,13.55,5.97,P ＜ 0.05 ).Among 5 subtypes,serum hs-CRP was the highest in large-artery atherosclerosis group after acute ischemic stroke,and cardioembolism group was the next.Serum hs-CRP reached the highest on three or five days after disease onset and decreased slowly.High levels of hs-CRP in large-artery atherosclerosis group indicated severe neurologic functional impairment and worsen prognosis.Conclusions ACI is closely related to serum hs-CRP level,which can be used as an subjective index for severity and prognosis with the lasting,high levels of hs-CRP levels predict poor prognosis.

Objective To explore the clinical efficacy of modified corneal ulcer debridement combining with anti-fungal agents in the treatment of keratomycosis(fungal corneal ulcer).Design Prospective case series.Participants Criteria for inclusion:1)fungal corneal ulcer was diagnosed under direct 10% KOH wet film microscopic examination;2)corneal ulcer located away from the center with superficial infiltration,or located in the center but in small size;3)depth of corneal infiltration was uncertain.From January,2007 to December,2009,141 cases of fungal corneal ulcer patients in Shandong Eye Institute affiliated to Qingdao Eye Hospital were recruited into this study.Methods All patients received modified corneal ulcer debridement including stripping off ulcer lesion as well as infiltrated tissue,and repairing ulcer fringe.For postoperative treatment,0.25% amphotercin B or 5% natamycin and 0.5% fluconazol eye drops were topically administrated with high frequency to the diseased eye.In the meantime,itraconalzole was orally taken as systematic treatment.Clinical efficacy of the above therapy was evaluated at last.Main Outcome Measurs Corneal ulcer infiltration,corneal epithelium reparation and recovery of vision acuity were closely observed following surgery.Results 10% KOH wet film examination showed that hypha was found in all of the 141 cases.The average time for postoperative follow-up was 29 days(from 14 to 60 days).All 141 cases of fungal corneal ulcer were completely healed,of which 127 cases were healed by taking corneal ulcer debridement surgery and anti-fungal medication,and the other 14 cases had to take penetrating keratoplasty(10 cases) or lameller keratoplasty(4 cases) due to uncontrolled infection.No recurrence was found during follow-up.The average time for healing in the 127 cases was 8.5 days,and among these cases,29 cases had a preoperative visual acuity below 0.05,80 cases between 0.05 and 0.3,and 32 cases between 0.3 and 1.0.Postoperative evaluation showed that 6 cases had a visual acuity below 0.05,42 cases between 0.05 and 0.3,93 cases(65.96%) between 0.3 and 1.0,and among 93 cases,81 cases(57.45%) had a visual acuity between 0.5 and 1.0.Conclusions The modified corneal ulcer debridement combining with anti-fungal agents has proved to be an effective treatment for fungal corneal ulcer.It greatly improves patient's visual acuity and shortens the disease duration.For cases of superficial or uncertain infiltration,corneal ulcer debridement enables better ulcer observation and provides guidance for further treatment.
