Objective To e xplore the clinical value of adrenomedullin on children with acute heart failure treatment and progno-sis.Methods Selected 58 cases of AHF children,40 patients with pneumonia,40 cases of children with congenital heart disease and 50 healthy children as the object,radioimmunoassay was taken to detected plasma adrenomedullin and endothelin level,and analysed correlation between AMD,ET-1 and cardiac function.Results Pneumonia complicated with heart failure group,congenital heart disease complicated with heart failure group plasma AMD,ET-1 levels were significantly higher than those in the control group, congenital heart disease group and pneumonia group (P<0.05),congenital heart disease group and pneumonia group of plasma AMD,ET-1 levels were significantly higher than those in the control group (P<0.05).Heart failure stage plasma AMD,ET-1 lev-els were significantly higher than those of early stage and recovery period (P<0.05),heart failure early stage plasma AMD,ET-1 levels were significantly higher than those of early heart failure recovery period (P<0.05).There was a significantly negative cor-relation between with AMD,EF-1 levels and CI,LVEF in AHF children (r= -0.614,-0.793,-0.618,-0.547,P<0.05);AMD mutation rate was significantly higher than that of EF-1 (P<0.05).Conclusion Plasma levels of ADM are closely relate with heart function in AHF children,through the determination of plasma ADM level can assessment treatment and the prognosis of children with AHF,and worthy of clinical application.

OBJECTIVE To investigate the efficacy of coblation for early glottic cancer. METHODS Twenty-two patients with early glottic carcinoma (Tis-T2) without lymph node metastasis accepted resection of laryngeal cancer lesions using transoral endoscopic coblation,without pre-operative or post-operative radiotherapy and chemotherapy. All the patients were followed up for 30 to 70 months. RESULTS No severe complications such as dyspnea and bleeding occurred in these cases.Only mild postoperative pain happened to the patients.All patients could swallow and speak after operation. No recurrence occurred in 21 cases till now. One case, with poorly differentiated squarnous cell lesion in the anterior commissure invading subglottic area, recurred 4 months after operation. Salvage partial laryngectomy was performed and no recurrence was found after salvage operation. CONCLUSION The result suggests that transoral endoscopic coblation is a good method for early glottic cancer. It is worth popularizing.

Thulium fiber laser is a novel laser of good potential in lithotripsy, which gained the attention of urology society in recent years. This article aimed to discuss Thulium fiber laser referring to lithotripsy mechanism, ablation efficiency, laser safety, clinical application and so on. Thulium fiber laser shares a similarity of lithotripsy mechanism with Holmium laser, whereas Thulium fiber laser has a higher ablation rate, thinner fragments, and smaller retropulsion compared to Holmium laser. Thulium laser may bring revolution in the field of laser lithotripsy.

Objective To investigate the risk factors of color-ectal cancer and to provide scientific basis for prevention of colorectai canc-er. Methods A 1:1 matched case-control study was carried out in Dalian including 200 cases with colorectal cancer and 200 controls. We analyzedthe data with the univariate analysis and mutivariate conditional logistic re-gressiou,theu calculated the Odds Ratio and the 95% confidence. Results Conditional logistic regression showed that history of constipation, family history of other tumor,intake much bloat food ten yeats ago and easily an-gry were the risk factors of colorectal cancer, and intake much fresh vegeta-bles ten years ago was the protective factors of colorectal cancer. One way analysis showed that following factors were the risk factors of coloroctal cancer:there were pollution factor around home 10 years ago, belly CT test,sleep over twelve o'clock at night,family history of coloroctal cancer, history of pries, appendicitis and the operation history of appendicitis, intake much fry and bake food,seashell and animal liver before ten years ago,of-ten feel strew, don't like to communicate with others,pessimism,don't harmonization with colleague. And iutaking much chicken meat, bean prod-ucts,garlic ten years ago,doing exercise and the frequency of exercise,high income were the protective factors of colorectal cancer. Conclusion Coloroctal cancer was the result of many factors. But the incidence of that in Dalian city was related to history of constipation, family history of other tumor, easily angry, intake less fresh vegetables and intake much bloat food ten years ago.

Methods Sixty patients of stable angina pectoris which belonged to the type of qi deficiency and stasis-phlegm were divided randomly into the treatment group and the control group,and each group has 30 cases. The treatment group was given Shiwei Wendan Decoction and the control group was given Tongxinluo Capsule for 4 week,one course. The changes of symptoms integral,ECG,clinical efficacy,blood-fat and CRP of the two groups were observed after the treatment. Results The total effective power of the treatment group was higher than that of the control group (P

[Objective] To explore the surgery protocol of the serious dislocation of acromio-clavieular joint,and compare the outcome of ORIF with AO/ASIF clavicle hook plate only to ORIF with eoraco-clavieular ligament reconstruction.[Method]Fity-two cases of the dislocation of acromio-clavicular joint were reviewed,Group A was ORIF only including 29 cases(male 20,female 9,mean age 45),according to the system of Rockwood,as TypeⅢ in 12 patients,TypeⅣ in 15 patients and TypeⅤ in 2 patients,the other 23 cases ORIF with eoraeo-clavieular l ligament reconstruction was Group B(male 15,female 8,mean age 50.6),according to the system of Rockwood,as TypeⅢ in 9 patients,TypeⅣ in 13 patients and TypeⅤ in 1 patients,AO/ASIF claviadar hook plates were used for all of the ORIF,and modified Weaver's method was used to reconstruct eoraco-clavieular ligament.Outcome was evaluated by Lazzcano scale after 8~12 months,and data was analyzed by SPSS 10.0.[Result]Good outcome was achieved in all of the patients,there was no significanty statistical difference between the two groups.[Conclusion]Clavicle hook plate is a kind of perfect internal fixation.Reconstruction of eoraco-clavleular ligament is not necessary if the AO/ASIF plate is used,unless serious avulsion of deltoid and trapezius muscle involved.

Objective To assess the safety and effica cy of local lidocaine anesthesia for pain control during transrectal ultrasound-g uided 10-core biopsy of the prostate. Methods Transrect al ultrasound-guided prostate biopsy was performed for 150 consecutive men beca use of an abnormal digital rectal examination and(or) abnormal transrectal ult rasound scan and(or) elevated prostate specific antigen.100 paients were rando mly assigned to receive an injection of 2% lidocaine (group 1,50 cases)or norm al saline(group 2,50 cases)into the lateral and apical periprostatic region,3 ml in each point,the other 50 patients(group 3) served as controls.Immediate ly after biopsy the pain score was recorded independently by a nurse using 10-p oint visual analog scale(VAS). Results The pain score range was 0 to 7.5 in the group 1,0 to 9.1 in the group 2 and 0 to 7.4 in the co ntrol group,the mean pain scores being 2.0 in the group 1,4.0 in the group 2 a nd 3.7 in the control group.The diffrence between group 1 and group 2、3 was sig nificant( P

0.05). Measured by KT-1000 arthrometer, the posterior tibial translations in the group of the uni-bundle at 0? and 30? flexion were (5.9?0.4) mm and (6.2?0.5) mm; but the posterior tibial translations in the group of the double-bundle at 0? and 30? flexion were (3.5?0.3) mm and (4.0?0.4) mm. It was of statistical significance (P0.05). Conclusion The clinical results of double-bundle PCL reconstruction is superior to that of the uni-bundle. Arthroscopic double-bundle PCL reconstruction is able to restrict the posterior tibial translation and restore the stability of the knee joint within its full range of flexion.

Conclusions Lateral and apical periprostatic anesthesia can significantly diminish the pain and discomfort in those undergoing transrectal prostate biopsy without increasing the incidence of complications.We recommend that this procedure be routinely applied to all patients undergoing transrectal prostate biopsy.

Objective To explore the effect of the antero-posterior translation of the femur on the maximum knee flexion and the relative movement of the femur for the three different kinds of prosthesis after total knee arthroplasty(TKA), such as posterior-stabilizing, fixed-bearing and mobile-bearing with the PCL retention. Methods 25 patients were selected for each kind of the prosthesis, and the inclusion criterion was based as the knee OA, good-excellent outcome after TKA, the flexion of the knee beyond 90?, and more than one year follow-up. The average age of these patients was 68 years with a range of 63 to 77 years, which involved 32 males and 43 females. The average preoperative knee flexion in the three groups were 77.8??15.1?, 80.1??12.9? and 76.4??12.7? respectively. The roentgenograms were taken both at the knee extension and maximum flexion, then the femur translation and the knee flexion were measured. Results The difference of the knee flexion among three groups preoperatively was of no significance. The maximum postoperative knee flexion in the posterior stabilizing, fixed-bearing and mobile-bearing was 118.0??7.1?,108.7??7.9? and 100.2??8.3? respectively. The analysis of variance showed the difference was of significance (F=32.86, P=0.0001). The relative movement about the femoral prosthesis in the three groups were (6.3?2.5) mm, (1.2?4.6) mm and ( 4.7?3.7) mm respectively (the posterior movement was positive, and the anterior was negative). The difference was of significance(F=57.71, P=0.0001). The femoral antero-posterior translation was proved to have correlation with the maximum knee flexion. Conclusion The femoral translation among three groups are different in manner, accordingly, the maximum knee flexion was different too.
