OBJECTIVE: To study the treatment effect of CO2 laser and self-made laryngeal dilator on the laryngeal stenosis. METHOD: Twenty-five patients with laryngeal stenosis were treated with CO2 laser and self-made laryngeal dilator. The laryngeal cavity scar was resected as much as possible by using CO2 laser and the laryngeal cavity was exposed by placing laryngeal dilator under general anesthesia. RESULT: The 24 cases of all were successfully decanulated 1 to 12 months after operation and could breathe freely. One case had second operation and was successfully decanulated 9 months after operation. The follow-up for 1 to 2 years showed all cases speaking well and 3 cases recurrence. CONCLUSION The method for treating laryngeal stenosis using CO2 laser and self-mande laryngeal dilator is effective, fewer complication, less invasive, and faster recovery. The laryngeal dilator is made simply and conveniently.

Objective To analyze the recent changes in features of joint injury caused by the fast running railroad train. Methods 1279 joint injuries o f the 10214 cases of train injury after the speeding up of the railway services from 1997 to 2003 were analyzed to find out their particular causal conditions, the severity of the injury, and the classification of the injuries, the correlat ion between which and recovery was also tested by AIS-ISS grading. Results Afte r the speeding up of the railway services, the incidence of joint injuries rose from 33.54% to 34.12%,the mortality rose from 22.88% to 30.33%,the multipl e joint severances rose from 19.84% to 34.19%,the open joint injury rose from 31.71% to 63.15%,and the mortality caused by multiple joint severances rose from 21.19% to 49.07%. Conclusions The incidence of multiple traumas resulted from the train is much higher than those resulted from other causes. Multiple t raumas caused by train are very difficult to deal with. The multiple organ dysfu nction syndrome (MODS) is a main factor to cause the death.

Objective:To evaluate the osteogenic activities of Bio-oss after combining with fibrin glue in reconstruction of canine mandibular defects.Methods:The second and fourth premolar teeth and the second molar teeth were extracted bilaterally, in 9 hibrid canines,resulting in 6 bone defects(1 cm?1 cm)in each canine.Bio-oss,Bio-oss+FG and FG were implanted into the bone defects of the second,fourth premolar teeth and the second molar teeth,respectively.Canines were executed in group of 3 after 4,8,and 12 weeks to observe the healing of soft tissues.The bone density was assessed by X-ray,the property of Bio-oss were observed via gross specimen,and the morphology of the newly-formed bone was observed by tissue sections.The proportion of newly-formed bone was obtained by computer image analysis(SAS software,analysis of variance).Results:StageⅠhealing of soft tissues was achieved in all animals.The bone densities were not significantly different between Bio-oss+FG and Bio-oss groups.The bone in FG group had transparent area.We also found that the bone in Bio-oss+FG group was closely combined and there were sccatered Bio-oss dusts in the soft tissues of the Bio-oss group.The newly-formed bone in the FG group was only found in the border between the defects and FG.The proportion of newly-formed bone was less in the Bio-oss+ FG group than in the Bio-oss group at 4,8,and 12 weeks after extraction(P

Objective To study the influence of Mutouhui extracts on hemorheology of U14 cervical cancer mice.Methods The U14 cervical cancer mice were divided into Mutouhui extracts high,middle and low dose group,Cisplatin Injection group,model group and blank comparing group.The influence on hemorheology change was observed after being given the medicine.Results The high,middle dose group of Mutouhui extracts and Cisplatin injection group could reduce the blood viscosity of U14 cervical cancer mouse in different shear,and hemotcrit of the low did not obviously change,groups of Mutouhui extracts plasma viscosity changed slightly.Cisplatin Injection group could reduce the blood viscosity,but did not obviously affect to the plasma viscosity.Conclusion Mutouhui extracts can reduce the U14 cervical cancer mouse blood viscosity,and improve the indexes of hemorheology.

Objective To explore the application of self-expanding stent and seperable detachable coil for interventional therapy in patients with wide-necked intracranial aneurysm.Methods 32 patients with wide-necked intracranial aneurysm received the interventional therapy by self-expanding stent and seperable detachable coil.After operation,the situation of the aneurysm occluded were observed by DSA immediately and followed up.Results The stents were successfully deployed in the 32 patients.The seperable detachable coils were occluded in the aneurysms in 29 cases.After operation immediately,the DSA showed that the aneurysms in 18 cases were completely occluded by seperable detachable coils,7 cases were 95% occluded,4 cases were 90% occluded.In the other 3 cases,the aneurysms were too small to be filled by seperable detachable coil,the stents were used only.All the parent arteries were no stenosis.18 h after operation,1 case died from multiple hemorrhage caused by thrombasthenia.Follow-up from 3 months to 1 year,DSA re-examination in 21 cases.Compared with the image immediately after operation,the imagings of DSA were no change in 12 cases,residual necks were disappeared in 5 cases and increased in 1 case.In the 3 cases which stents used only,the aneurysms were no development completely in the 2 cases and decreased in 1 case.6～18 months followed up in 26 cases,the rebleeding and cerebral infarction were no occurred.Conclusions The self-expanding stent is very flexible,secure,and effective.It can good support for the wide-necked aneurysms to be occluded by seperable detachable coils and effective promoting the small aneurysms healing.

[Objective]To discuss the injury severity and treatment of 236 patients with upper limb injuries in Wenchuan Earthquake.[Method]The basic informations of patients with upper limb injures in Wenchuan Earthquake,and the injury mechanisms,clinical symptoms and treatment were collected and analyzed.[Result]In 236 cases of patients with upper limb injuries,there were 208 patients,378 cases with fracture,and 64 cases with open fracture.There were 35 cases of clavicle fracture,31 cases of scapula fracture,113 cases of humerus fracture,46 cases of ulna fracture,87 cases of radial fracture and 66 cases of carpometacarpai phalangeal fracture.Fifty cases received debridement and suture,60 cases received fracture reduction and internal fixation and 7 cases received external fixation.Totally,19 limbs were carried on amputation,and only one patient died of hyperkalemia and combined injury.[Conclusion]Analysis of patients with injury mechanisms,clinical symptoms and treatment can provide advices for rescuing and treating of patients with upper limb injuries in earthquake or other disaster cases.

Objective To study the expression of hMLH1, hMSH2 and their association with clinico-pathological characteristics in hepatocellular carcinoma(HCC). Methods The expression of hMLH1 and hMSH2 in 37 HCC tissues was detected by SABC immunohistochemistry. Results The positive rate (score) of hMLH1 and hMSH2 expression in HCC was 48.7%(1.65?1.70) and 59.5%(2.30?1.96), respectively, which was obviously lower than that in the adjancent tumor tissues with 83.8%(3.30?1.37), and 86.5%(4.30?2.01), and in the normal liver tissues with 88.2%(3.88?1.98) and 82.3%(4.29?1.83), respectively(P

Objective To screen HCV NS3 mimotopes by using monoclonal antibody and phage peptide library. Methods Using HCV NS3 monoclonal antibody as selective molecule, a 7 mer phage peptide library was biopanned and positive clones were selected by ELISA, competition assay and DNA sequencing. Results 13 positive clones were chosen for DNA sequencing. From the experiment and sequen-cing comparsion results, one epitope was confirmed as the mimotope of HCV NS3. Conclusions HCV mimotope is obtained by phage peptide library screening.
