Objective To detect the chromosomal aberration in the cells of renal carcinoma and to evaluate the rela-tionship between the chromosomal aberration and development of renal carcinoma.Methods CGH technology was used to analyze the global genomic aberration in cancer cells from 12 patients with renal carcinoma.Results All of 12 cases deeeted by CGH showed chromosomal aberrations.The common extension regions of renal carcinoma were 1p,4p,5q,7p,9p and 16p.The common deletion regions of renal carcinoma were 3q,4q,6q,9q,14q and 18q.Conclusion The hereditary material of renal carcinoma is unbalanced.The extension and/or deletion of chro-mosome may facilitate the occurrence of renal carcinoma.

OBJECTIVE: To investigate the therapeutic effects of 768 coblation treatment in children with obstructive sleep apnea-hypopnea syndrome. METHOD: A review of 768 coblation treatment in children with obstructive sleep apnea-hypopnea syndrome was presented with respect to the sleep monitoring results, therapeutic effects and complications. RESULT: The time of pseudomembrane ablate was 10-14 d after operation. There were 11 patients occurred Secondarily bleeding within 1 week and 21 patients lymphatic tissue hyperplasia compensatorily within half a year after operation. After operation 3 months, the sleep Monitoring results were improved remarkably (P < 0.01) and the symptoms of snore and choke improved. CONCLUSION Coblation treatment in children with obstructive sleep apnea-hypopnea syndrome can reduce bleeding volume and improve obstruct syndrome apparently. The treatments of tonsils and adenoids differ with the characteristics of children and tympanotomy was fit for chil dren with secretory otitis media.

Reflux cholangitis is a common complicatian follawing cholangio-jejunostomy,During a period between July 1981 and June 1994 the authors have performed plastic valve in 116 cases undergo- ing Cholangrojunostomy adding a plastic valve to each of three forms of cholang iojejunostomy that was Y-shape,loop-shape,and interposition-shape in Order tO prevent reflux.There was no inhospital mor- tality and fistula,and symptoms related to biliary tract disappeared in 92 cases(79.3%)during fouow- up.

OBJECTIVE: To investigate the result of child-type micro-sensitive mattress sleep monitor on obstructive sleep apnea-hypopnea syndrome in children. METHOD: The PSG and child-type micro-sensitive mattress sleep monitor were synchronously performed on 58 cases of children with OSAHS. The breathing and sleep metrics were compared. RESULT: By PSG monitoring, 41 cases were diagnosed as mild OSAHS, 14 cases were moderate and 3 cases were severe. The results of mattress system monitoring showed mild OSAHS in 37 cases, 16 cases of moderate and severe OSAHS in 5 cases. Seven patients diagnosed as mild OSAHS monitored by PSG were classified as moderate by mattress system monitoring; three cases diagnosed as mild OSAHS by mattress system monitoring system were diagnosed as moderate by PSG. Among 14 cases of children diagnosed as moderate by PSG, three cases were diagnosed as mild by mattress system monitor and two cases as severe. Children diagnosed as severe by PSG got the same result by mattress system monitor. Two kinds of sleep monitoring methods were compared and there were no statistically significant difference in AHI (t = 2.316, P > 0.05), deep and shallow sleep constituent ratio (t = 2.280, t = 2.388, PF > 0.05). while there was significant difference in REM period Sleep constituent ratio (t = 3.135, P < 0.01). CONCLUSION Child-type micro-sensitive mattress is in good agreement with the PSG for diagnosing OSAHS in children, which can be used as a monitoring method in clinical work.

Objective To explore the diagnostic value of SPECT/CT on fracture healing.Methods A total of 28 patients (13 males,15 females; average age 45.3 years) with fracture were enrolled.All underwent metal fixation.SPECT/CT scans were performed at least 6 months after the metal fixation.X-ray examination before SPECT/CT showed equivocal fracture healing.The fracture delayed union or nonunion were judged by degree of uptake as well as uptake pattern around fracture site.Final diagnosis was confirmed by surgery or follow-up X-ray film.Results Among 28 patients,15 showed delayed union (confirmed by follow-up),and 13 showed nonunion (confirmed by surgery).There were 13 screws in 6 patients showed abnormal uptake,suggesting screw loose (confirmed by surgery).Conclusions SPECT/CT imaging could be of clinical significance in assessing fracture healing.

objective To investigate the recurrence of stroke,clinical prognosis and vascular changes in patients with ischemic stroke due to middle cerebral artery stenosis. Methods The ischemic stroke patients with symptomatic middle cerebral artery stenosis were enrolled continuously and followed up prospectively for six months. The recurrence of ipsilateral stroke,clinical prognosis and dynamic changes of vessels were analyzed. Results Eighty patients were included,and 20.0% of the patients(16 cases)presented with recurrence of ipsilateral ischemic stroke and 56 cases (70.0%)with a good outcome(modified Rankin scale[mRS]≤1)during the 6 months follow-up;38.6% patients (27 cases) presented with significant vascular changes with progression in 12 cases (17.1%)and regression in 15 cases (21.4%). Conclusion The patients with simple symptomatic middle cerebral artery stenosis have an high rate recurrence of ipsilateral stroke but have good prognosis;Lesioned artery of the majority of patients in the short period after stroke was stable,but vascular stenosis in some patients could appear progression or remission.

In current study,by means of analysis of client and administrator needs,we constructed "internal medical resource database" based on internet,which has 5 modules including database itself,communication on line,resource searching,recent updating and resource statistic.We hope the establishment of "internal medical resource database" can do a favor for the similar resource database.

OBJECTIVE: To investigate the treatment for lingual thyroglossal duct cyst by low temperature coblation on endoscope. METHOD: Eleven cases of lingual thyroglossal duct cyst were treated by low temperature coblation on endoscope,to observe the curative effect and complication. RESULT: Eleven cases of lingual thyroglossal duct cyst were satisfied after operation, without serious complication. There were no recurrence during a followed up for 1-3 years after operation. CONCLUSION The operation for lingual thyroglossal duct cyst by low temperature coblation on endoscope was easy,safe and effective.

OBJECTIVE: To evaluate the effect of the coblation under endoscopy on epiglottis cyst. METHOD: One hundred and ninety-three patients with epiglottis cyst were treated with coblation under endoscopy. Follow-up study was performed from 1 month to 6 months after treatments. RESULT: All 193 cases with epiglottis cyst were primary cured without serious complication and the cure rate was 100%. Moreover, the minor hemorrhage (1-5 ml) was observed. CONCLUSION The coblation under endoscopy on epiglottis cyst was safe, effective and minimally invasive.
