Objective To compare the efficacy and side-effects of combined spinal-epidural anesthesia(CSEA)and epidural anesthesia(EA)for ureteroscopic pneumatic lithotripsy.Methods A total of 60 patients with ureteral calculi(ASA gradeⅠ-Ⅱ)were divided into A and B groups randomly(30 in each).CSEA was performed in group A,and EA was carried out in group B.Anesthetic effects and side-effects were observed in both the groups.Results Anesthetic effects were satisfying in both the groups,no patient had headache after the operation.The onset time of anesthesia in group A was shorter than that in group B [(7.2?4.1)min vs(17.4?3.3)min,t=-10.615,P=0.000].The level of motor block of CSEA was stronger than that of EA(?2=40.000,P=0.000).No significant differences were found between the two groups in the number of patients who developed hypotension(6 in group A and 3 in group B,?2=0.523,P=0.470)or shivering(9 in group A and 6 in group B,?2=0.800,P=0.371).Conclusions Both CSEA and EA are applicable to ureteroscopic pneumatic lithotripsy.CSEA is more efficient than EA.

[Objective] To investigate the feasibility of posterior interbody parvule-impacted bone graft fusion.[Method] A retrospective study was performed in 31 patients admited to our hospital in 2003~2006(M=14,F=17).The ages were 55 to 80,with an average of 66.2 years.There were 9 cases of spondylolisthesis,6 of degenerative unstability and 16 of developmental stenosis.All patients underwent posterior interbody impact bone graft fusion and pedicle screw fixation.The pre-and post-operative JOA score were used to calculate the improvement rate.The postoperative bending-extending plain films were taken to observe whether the fusion was successful.[Result]All patients were followed up for 12~18 months.Three patient had leg symptoms at postoperation and were released 3 months later.Thirteen patients had fusion at 6 month,16 had union at 12 month,and 2 had union at 18 month.The lumbar lordosis angle and intervertebral height got significant restoration.The spinal fusion rate was 100%.No dura tear leakage of cerebrospinal fluid or wound infection was found.No graft absorption,displacement or collapse occurred.There were 16 cases excellent,12 cases good,and 3 cases fair.JOA score was 24~29(average 27.4?1.9)at postoperation.The improvement rate was 89.4%.[Conclusion] Posterior interbody parvule-impacted bone graft is a feasible fusion method.The method is simple and cheap,with advantages of less injury and high fusion rate.

Objective To investigate the diagnostic significance of cytology and telomerase activity in the exfoliated cells of cardia obtained from endoscopic brushing in the cardiac cancer.Methods The technique of the qualitative TRAP siver staining and quantitative TRAP PCR ELISA were employed to detect telomerase activity in the exfoliated cells of cardiac obtained from endoscopic brushing in 72 cases with cardial lesions,cytological diagnosis was made at the same time.Results Telomerase activity with cardiac cancer group(1\^521?0\^192)was significantly higher than that with cardialitis group(0\^065?0\^014).Positive rate of telomerase activity detected in cardiac cancer group(88\^89%)was significantly higher than that with cardialitis group(11\^11%).Positive rate of telomerase activity detected in cardiac cancer group(88\^89%)was significantly higer than cytological examination(77\^78%).The diagnostic rate of cardiac cancer was improved to 93\^33% if telomerase activity and cytology were examined at the same time.Conclusion Results show that the combination of cytology and telomerase activity in the exfoliated cardiac cells may be an effective and sensitive method in the diagnosis of cardiac cancer.This research can be a basis for the mass screening of cardiac cancer.

Objective To study the expression of CD105 in laryngeal carcinoma and to evaluate the clinical significance of microvessel density(MVD).Methods Pathologic paraffin-embedded sections and clinical data from 40 patients with primary squmamous cell carcinoma of larynx were studied through immunohistochemistry.Microvessel density(MVD) highlighted by CD105 and CD34 were counted.Results CD105 expression in tumour tissue was significantly higher than normal health mucosa.The mean CD105-MVD value of T3 and T4 tumours showed a significantly deeper staining than T1 and T2;The mean CD105-MVD value of tumours with metastasis was also markedly higher than tumours with no metastasis;The diffenerce of mean CD105-MVD value between in 16 patients with recurred laryngeal carcinoma and in 20 patients with unrecurred laryngeal carcinoma for two years of follow-up was markedly significant(P

OBJECTIVE: To evaluate the clinical efficacy on the treatment of the low-middle frequency sudden hearing loss with postaurical injection of methylprednisolone. METHOD: The 80 cases of the low-middle frequency sudden hearing loss were randomly divided into postaurical injection and oral hormone groups. The postaurical injection group (42 cases) received the postaurical injection of methylprednisolone, 40 mg/2 d, combined with the treatment of Ginkgo dipyidamolum and Alprostadil for 14 d; The oral hormone group (38 cases) received the oral prednisone, 1 mg/kg/d, administrated once on the morning for 3 d, if effective, prolonging for another 2 d, as mentioned above for Ginkgo dipyidamolum and Alprostadil. RESULT: The total effective rate was 88.10% in postaurical injection group and 86. 4o%in oral hormone group. There was no significant difference between the twbogroups( P> 0. 5). CONCLUSION Postaurical injection of methylprednisolone for the low-middle frequency sudden hearing loss is effective, safe and simple, which may be an alternative for systemic administration of gulcocorticoid.

Objective To evaluate the feasibility of real time elastosonography in estimating the characteristic of nodules in resected hepatocirrhosis specimens.Methods Thirty-eight reseeted hepatocirrhosis specimens underwent elastosonography.The nodules that have drawn attention were performed elastosonography through rhythmic pressing and releasing the probe by manual form on the liver.The hepatic strain on the region of interest was shown by chromatic scale.To compare nodules rigidity with surrounding hepatic tissues, hepatocirrhosis nodules were classified into hard nodules, medium rigidity nodules, mixture of hard and soft nodules, and soft nodules.All nodules were confirmed by pathology.Results Forty-four nodules of 38 hepatocirrhosis exemplar received real time elastosonography.Of 44 nodules, hard nodules were 18,of which 12 (66.7%) were hepatoeellular carcinomas, 2 (11.1%) were dysplasia nodules, 4 (22.2%) were regenerative nodules.Medium rigidity nodules were 7,all were regenerative nodules.Mixture of hard and soft nodules were 11, of which 8 (72.7%) were hepatocellular carcinomas, including 4 accompanied necrotic tissue, 1 (9.1%) was dysplasia nodules accompanied necrotic tissue, the other 2 (18.2%) were regenerative nodules accompanied necrotic tissue.And soft nodules were 8, of which 4(50.0%) were necrotic nodules, 1 (12.5%) was dysplasia nodules accompanied canceration, 1 (12.5%) was hepatocellular carcinoma,2(25.0 %) were regenerative nodules.Conclusions Real time elastosonography can effectively evaluate the comparative rigidity on hepatoeirrhosis nodules,and thus may have potential usefulness on estimating the characteristic of hepatocirrhosis nodules.

Objective Objective To study the influence of NS-398,a selective cyclooxygenase-2 inhibitor on the radiosensitivity of human esophageal carcinoma cell line EC9706 cell. Methods EC9706 cell, highly expressing COX-2, had been incubated with NS-398 at 10、20、50 and 100??mol/L for 24?h or 48?h before irradiation ranging from 0 to 10?Gy. Cell survival was measured by a standard clonogenic assay after 8 days of incubation. Apoptotic percentage was measured by FCM and DNA fragmentation by agarose electrophronesis. Results The senstization enhancement ratios (ratio of D_q) in EC9706 cell were 1.11, 1.24, 1.40, 1.54 at 10, 20, 50, 100??mol/L of NS-398 for 24?h pre-incubation and 1.11, 1.27, 1.58, 1.67 for 48?h pre-incubation, which showed a dose-dependant and time-dependant manner. FCM analysis revealed a higher sub-G_1 cell peak in NS-398 group after irradiation. Agarose electrophronesis showed a marked ladder. Radiation-induced apoptosis was enhanced by NS-398 (P
