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.

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.

Objective To investigate the best models of esophageal cancer surgical approaches,lymphadenectomy ranges and postoperative comprehensive treatment.Methods From January 1998 to December 2007 in 10 years,1 162 cases of different parts with esophageal cancer were analysized which were treated with surgically adopting sequential abdomen,chest,neck three-incision approaches.Taking three-step screening way of preoperative imaging,preoperative ultrasound localigation fineneedle aspiration biopsy cytology and intraoperative rapid fieezing pathological examination were applied to make the selectivity of the first-times cervico-thoraco-abdominal three-field lymph node dissection (3FLND),first-times standard thoracoabdominal two-field lymph node dissection (2FLND) and second-times third-field cervical lymphadenectomy.Meanwhile,we implemented actively postoperative comprehensive treatment and observed the overall clinical efficacy and long-term survival.Results In the group of 1 162 cases with esophageal cancer surgery.The operating resection rate was 100 ％,Radical resection of 97.6 ％ (1 134/1 162).Perioperative overall complication rate was 16.4 ％ (191/1 162).Anastigmatic fistula was 0.6 ％ (7/1 162).Five cases dead in 30 days after surgery.The whole group of lymph node metastasis rate was 52.6 ％ (611/1 162),lymph node metastasis degree in 12.1％ (3 092/25 564).Full group of the first-times 3FLND was 348 cases.The positive rate was 94.8 ％ (330/348),Implementing the first-times 2FLND was in 814 cases and the second-times thirdfield cervical lymph node dissection was performed in 89 cases.The postoperative complications of the 3FLND was significantly higher than that of 2FLND (23.6 ％ vs 13.4 ％).The difference was statistically significant (x2 =18.37,P ＜ 0.001).However,The difference was not statistically significant between 3FLND and 2FLND (P ＞ 0.05).There is no significant difference between the first-times 3FLND with the second-times 3FLND accumulating survival (P ＞ 0.05).But different degree of lymph node metastasis determined prognosis.The difference was significant (x2 =35.57,P ＜ 0.001).In our group the postoperative comprehensive treatment application rate was 87.2 ％.Surgery combined with comprehensive treatment overall 1,3,5 years survival rates were 92.1％,69.2 ％,49.6 ％ respectively.Conclusions The sequential three-incision approaches and selectivity of lymph node dissection have the radical nature thoroughly,fewer complications,high quality of life and the long-term survival advantages.It should be a widely used method in the clinical surgery of the esophageal cancer.Implementing the three-step screening way to selecting the first-times 3FLND,the firsttimes 2FLND and the second-times third-field cervical lymphadenectomy that have targeted strongly and high accuracy,a definite object in view and avoiding patient excessive trauma.Applying the comprehensive treatment after surgery and the re-treated of patients with recurrence that can further more improve the longterm survival of patients.The comprehensive treatment should be the target direction of the future development of esophageal cancer.
