Objective To investigate the different operative style for the intraspinal extramedullary neoplasms in the cervical vertebrae as well as evaluate the clinical effect of titanium net for spinal canal reconstruction and bone autograft after laminectomy. Methods Since March 2002 to September 2008, 26patents (14 men, 12 women) with the intraspinal extramedullary neoplasm in the cervical vertebrae. The average age was 38 years (range, 6-76 yr). According to Frankel classification, there were 26 cases for grade B before operation, 8 cases for grade C, 11 for grade D, and 4 for grade E. All patients underwent hemilaminectomy (as group HL) or total laminectomy combined with spinal canal reconstruction with titanium net (as group TL). Recovery of nerve function and bone fusion were recorded. Preoperative and postoperative cervical curvature index and ranges of neck motion were recorded and compared. Results Among the 3cases with incomplete paraplegia, neurological status ameliorated from Frankel grade B to C; 8 cases of Frankel grade C recovered to grade D; 11 cases of Frankel grade D improved to grade E in 10 cases and 1to grade D. Bone fusion was formed on the titanium net and spinal stability was well after operation. Loss of cervical curvature indices was 2.2±2.3 in group HL and 4.3±2.5 in group of TL, and the difference was of statistically significant (t=2.05,P＜0.05). At the same time, loss of ranges of neck motion was 1.3°±1.2°ingroup of HL and 9.2°±4.1°in group TL, significant difference was also seen (t=1.71 ,P＜ 0.05). Conclusion Hemi-laminectomy approach to intradural lesions lends itself well to eccentric tumors with smaller size. For the cases of total laminectomy, it is necessary and reliable to reconstitute integrity of spinal canal with titanium net and bone autograft.

Eighty cases of intrauterine adhesions who received adhesion separation technique were divided into two groups equally. The control group was placed intrauterine device and ballon catheter in intrauterine,and received o-ral female estrogen cycle treatment. The test group with the same treatment was added growth hormone treatment. Three months later,all of the patients were checked the hysteroscopy and intrauterine device was took out, also the uterine cavity form,and follow-up recovery of endometrial and menses were evaluated. Then it showed:①Endome-trial thickness increased by an average of (1.73±0.83) mm in the test group,while the control group average in-creased by (1.10±0.66) mm. The difference was statistically significant (t=3.73,P<0.01).② The re-adhe-sion rate was 45.0% in the control group,while it was 32.5% in the test group,respectively. The difference was not statistically significant. ③ The difference of mensual recovery between both groups was not statistical significant. Therefore growth hormone can promote the growth of endometrium of intrauterine adhesions after resection of adhe-sions.

BACKGROUND: Posttraumatic stress disorder(PTSD) arises as a delayed and /or protracted response to a stressful event or situation of an exceptionally threatening or catastrophic nature. There have been reports about natural disasters causing PTSD, but there have been few reports about PTSDcaused by technological disasters. Our study investigated the mental status of those survivors after a serious explosion.OBJECTIVE: To investigate the characteristics and the factors of impact of PTSD caused by technological disasters.DESIGN: A case controlled study of the survivors of a momentous explosion.SETTING: A provincial mental health center.PARTICIPANTS: A serious explosion happened in Urumqi on September 8, 2000. Twenty-eight survivors(as the study group) who were still hospitalized for treatment 3 -5 months after the accident were involved in this study. And in the control group were 30 normal persons whose general demographic data were the same as those patients.METHODS: A psychiatrist told the subjects the following: The objective and meaning of the test, and explained the self-making questionnaire about their general condition, symptom checklist (SCL-90), self-rating anxiety scale (SAS), self-rating depression scale(SDS), cornell medical index(CMI), the questionnaire on dealing styles, the questionnaire on social support, and others-evaluating scale, incident effect scale(IES); a list of stress reaction symptoms.MAIN OUTCOME MEASURES:Main resulta:①Clinical feature of PTSD caused by the technological disaster.②the related factors to PTSD in the technologal disaster.Secondary results: Comparison of the results between the two groups in IES, CMI, SDS and SAS.RESULTS: A total of 22(79% ) survivors met the criteria as PTSD. There were significant differences in all the assessments(IES, CMI, SDS, SAS,SCL-90) between the study group and the control group (t =3.62-8.17, P ＜ 0.01 ) . The diagnosis of PTSD was positively correlated with the level of traumatic exposure( r = 0. 420, P ＜ 0. 05), and negatively correlated with the degree of satisfaction with the post-event solutions( r = 0. 420, P＜ 0.05), positively correlated with IES scoring and the level of heart pain ( r = 0. 389 - 0. 665, P ＜ 0. 01 ) . The total scores of IES were positively correlated with the level of exposure ( r = 0. 478, P ＜ 0.05 ).CONCLUSION: The incidence of PTSD after explosion was high, and its occurrence was related with the degree of exposure in the event and that of the satisfaction with the post-event solutions.

Objective To investigate the clinical significance of I-FISH for detection of genomic abnormalities in MM. Methods Twenty newly diagnosed MM patients(seven cases at stage Ⅰ , five cases at stage Ⅱ and eight cases at stage Ⅲ according to Bataille staging) were analyzed by combining the technique of CC (R-binding stain) and I-FISH [ including GLP13q14 (RBI gene), GLP17p13. 1 (P53 gene),GLP13q14. 3(D13S319) ,GLP1q21 ,GLP14q32(IgH gene) DNA sequence probes]. These two methods were compared for the detection rates of chromosomal and genomic abnormalities in MM and the association between genomic abnormalities and Bataille stages was also analyzed. Results CC examination showed only 1 case [5% (1/20) ] was found complex chromosomal abnormalities--46,XX,-2,del(3) (p21) ,add(6)(q26) ,der(10)(q26),der(14)(q32), + mar, inc[6]. While I-FISH assay showed that 12 cases [60%(12/20) ] were found genomic abnormalities. The frequencies of RB1, D13S319 and P53 were all 30%(6/20), and the frequencies of IgH gene and 1q21 were both 20% (4/20). The detection rate of the I-FISH was much higher than CC (χ2 = 9. 09, P = 0. 001) according to paired χ2 test. Of 20 patients,6 cases had RB1 gene abnormality, 1 case at stage Ⅰ , 2 cases at stage Ⅱ and 4 cases at stage Ⅲ. Of 20 patients, 6 cases had D13S319 gene abnormality, 2 cases at stage Ⅰ , 1 case at stage Ⅱ and 3 cases at stage Ⅲ. Of 20 patients, 6 cases in 20 had P53 gene abnormality, 2 cases at stage Ⅰ and 4 cases at stage Ⅲ. Of 20 patients, 4 cases had 1q21 gene abnormality, 2 cases at stage Ⅰ and 2 cases at stage Ⅲ. Of 20 patients, 4 cases had IGH gene abnormality, 1 case at stage Ⅰ and 3 cases at stage Ⅲ. Conclusion Ⅰ-FISH has higher detection rate for the genomic abnormalities in MM and can be used in detection of MM patients in different Bataille stages.

Objective To study the use of ultrasound-guided percutaneous transhepatic cholecystostomy (PTGD) followed by selective minilaparotomy cholecystectomy (MC) for acute obstructive cholecystitis in the high-risk elderly.Method A retrospective study was conducted on 120 patients who received ultrasound-guided PTGD followed by selective MC from January 2008 to December 2010.Results PTGD+ MC were performed successfully on 120 patients with acute severe obstructive chole cystitis.In all the patients,the abdominal pain was relieved within 2-3 h of operation,and the temperature decreased to normal from 24- 48 h after operation.The average time of drainage was 10 days.In 97 patients MC was performed 1 week after PTGD,and in 23 patients 2 weeks after PTGD.Bleeding from gallbladder bed occurred in 1 patient.No patient suffered from bile leak.There was no major complication or death after PTGD+ MC.Conclusion PTGD followed by selective MC is a simple,efficacious and minimally invasive treatment for high-risk elderly patients with acute obstructive cholecystitis.

Objective To explore the cause of acute myocardial ischemia early after coronary artery bapass graft (CABG) and surgical management on it. Methods From 2001 to 2009, 28 patients underwent urgent reoperation early after CABG due to acute myocardial ischemia. The incidence of reoperation is about 0.02%. The cause of reoperation inclouded early graft occlusion (10 cases) ,IMA damage or injury during harvesting(9 cases), inexactitude distal anastomosis(2 cases)and radial artery spasm(4 cases). The mean interval time between two operations was 8 hours. Reoperation was done under offpump bypass in 2 patients and on-bypass used in other patients. Unsatisfactoey graft were substituted with new graft material and thrombotic was removed. If LIMA was the reson for myocardial ischemia, an additional vein graft was inserted. The spasm radial artery were substituted with new vein graft. Completely revascularization was used in re-do CABG. Results Two patients died during reoperation. 8 patients was died between 1 day and 14 days after reoperation. IABP was used in 16 patients,which 2 patients received ECMO suppord and 2 patient received LVAD suppord at mean time. Conclusion There have very high mortality in acute myocardial ischemia early after CABG. The early diagnosis and correct surgical management can improve the rates of survival. The active prevent should be emphasized during the first CABG.
