The value and detection of right ventricular in circulation have been paid more attention,.Because of the defects in traditional method,Tei index is the method in right ventricular measurement.The Tei index is sensitive in assessing RV function of patients with congenital heart disease.It is not affected by valve regurgitation and RV geometry.The Tei index is accurate and simple in estimating right ventricular function in congenital heart disease and is valuable and invasive index in estimating right ventricular functions.

Abstract?AlM: To observe the anterior chamber angle shape of patients with diabetic retinopathy ( DR) at different stages using OCT, and to explore a more sensitive and accurate glaucoma preventing measure.?METHODS: A total of 613 cases of DR patients were divided into proliferation phase group ( 353 cases ) and background phase group ( 260 cases ) , another 100 cases of patients with only diabetes were selected as control group. OCT was used to detect the anterior chamber angle related parameters, including angle opening distance ( AOD) , trabecular-iris space area ( TlSA) , angle recess area ( ARA ) , anterior chamber depth ( ACD ) and anterior chamber angle ( ACA) .?RESULTS: There were significant difference among AOD500, AOD750, TlSA500, TlSA750, ARA500 and ARA750 of control group, proliferation phase group and background phase group ( P< 0. 01 ). The proliferation phase group was the lowest, AOD500, AOD750, TlSA500, TlSA750, ARA500 and ARA750 were 0. 60 ± 0. 22mm, 0. 78 ± 0. 39mm, 0. 22 ± 0. 12mm2 , 0. 45 ± 0. 19mm2 , 0. 29 ± 0. 18mm and 0. 46 ± 0. 15mm, respectively. There were significant difference among ACA500, ACA750, ACD500 and ACD750 of control group, proliferation phase group and background phase group ( P< 0. 01 ). The proliferation phase group was the lowest, ACA500, ACA750, ACD500 and ACD750 were 30. 29o ± 8. 19o, 21. 20o ± 7. 40o, 2. 32 ± 0. 23μm and 2. 52±0. 16μm, respectively. ln addition, ROC results indicated that all these indices exert significant difference on evaluating the stage of DR. ?CONCLUSlON: Anterior chamber angle shape detected using OCT can reflect the change of retinopathy. OCT is an accurate and simple technique for detecting DR staging.

Objective To study the effect of embolization of gastric coronary and short veins on the control of hemorrhage from gastric fundal varices. Methods Thirty-two patients with liver cirrhosis and hemorrhage from esophagus and fundal varices, who still had variceal bleeding after endoscopic banding or sclerosing of esophageal varices were included in the study. Gastric coronary and short veins were (embolized) by percutaneous, transhepatic embolization with absolute alcohol, steel ring, or gelfoam. The follow-up of 3 to 11 months was carried out after embolization. Results The follow-up endoscopy showed that the varices of gastric fundus disappeared completely in 21 of 29 patients (72.4%), and (eleminated) partially in 8 patients (27.6%). Only one patient (3.1%) had re-bleeding due to portal (hypertensive) gastropathy in the follow-up period. No obvious complication was found in these patients. Conclusions The varices of gastric fundus could be obliterated by percutaneous, transhepatic embolization of gastric coronary and short veins.

[Objective]Microsurgical lumbar discectomy(MSLD)and microendoscopic discoectomy(MED)were compared in methods and curative effect for providing the experience and therapy evidence of lumbar disc herniation(LDH).[Method]It was retrospectively analyzed that mono-segment lumbar disc herniation were treated in minimal invasion in our hospital.MSLD was 45 cases and MED was 32 cases.Operation time,operation information,complication,hospital time and curative effect were compared.[Result]The satisfactory rate of two groups were both beyond 90% and no significant deviation was found.The incision of MED was obviously shorter than MSLD and the operation time of MED was longer than latter.[Conclusion]The curative effects of two minimal invasion methods are satisfactory.But the indication of MED is limited obviously and the method has not obvious predominance by compared with MSLD.MSLD is an more ideal minimal invasion operation at present.

Objective To evaluate the efficacy and complication of endoscopic dense ligation for bleeding esophageal varices(EV). Methods 128 cases of EV experienced varcies ligation, and 16～22 points(average 18.8 points) of the varices were ligated by using dense ligation, while only 5～6 points were ligated in common ligation (common method) for varices. All patients got one to two times of ligation therapy. Results In dense ligation group, the rate of prompt hemostasis was 96.9%, rate of elimination of EV was 92.2% with one therapy, and 96.9% with twice therapy, while the rate of bleeding was 0.8%. In common method the rates were 95.7%, 42.6%, 64.7% and 7.1% respectively. Between the two groups, the rate of elimination of EV and rebleeding had significant difference (P

ObjectiveTo explore the diagnostic methods and surgery pattern at the first time of spontaneous perforation of congenital choledochal cyst.MethodsEleven cases(4 male,7 female) with spontaneous perforation of congenital choledochal cyst were 6 months to 5 years old,and their average course of disease were 4 days.Gustily abdominal distension,abdominal pain,crying and fever were present in all cases.Jaundice(7 cases) and emesis(5 cases) appeared.All cases were detected with physical sign of peritonitis by physical examination.Choledochal cysts were confirmed by CT or B ultrasound in 8 cases.All cases accepted abdominal paracentesis and biliary ascites was drawn.Three different operative procedures were performed:choledochocyst excision & Roux-Y choledocho-jejunostomy(2 cases),choledochotomy with T-tube drainage(3 cases),and cholecystostomy(6 cases).Nine children receiving external drainage operation accepted a second operation to rebuild biliary tract(choledochocyst excision & Roux-Y choledochoje-junostomy) after 3 to 6 months.ResultsAll cases had got satisfactory therapeutic efficacy without any grave complication such as fistula of anastomotic stoma,infection of biliary tract or obstruction of biliary tract.During operation,perforations were located in the juncture of choledochus and cystic duct in 5 children and were not found in the other 6 children.In the second operation,the cases receiving cholecystostomy had less peritoneal adhesion,anatomic structure changes,haemorrhage[(30-50) mL vs(100-200) mL] and operation time[(2.5-3.0) h vs(3.5-5.0) h] than those receiving choledochotomy with T-tube drainage,and did not appear inadequate drainage for cystic duct obstruction.ConclusionsFor children with more organ inflammatory edema and adherence and in a bad overall condition,the first-time operation of cholecystostomy is more reasonable.

Objective To study the clinical characteristics and effects of surgical treatment of children with thalamic tumors.Methods The clinical data of 22 cases were retrospectively studied and followed-up 6 months to 9 years.Results There were 13 boys and 9 girls,their ages ranging from 3 to 13 years.The average duration of symptoms before diagnosis about 2 months.Headache and papilledem were the most symptoms and signs,respectively.Most children′s thalamic tumors were low grade tumors with clear verge.In this group,good results were obtained that total remove 9 cases,subtotal remove 8 cases,partial remove 3 cases,biopsy 2 cases and no surgical death.Conclusions Clinical character of children thalamic tumors is distinct and good surgical results in the nearly future.The long results are determined by type of pathology.

Objective To explore the effect of applying problem-based learning(PBL)in clin-ical anesthesiology demonstration for clinical undergraduates. Methods Eighty-nine 2009 clinical undergraduates were divided into two groups:experimental group and control group. Students in ex-perimental group received PBL while those in control group received traditional teaching. The effect was evaluated according to the results of case examination and investigation table. The results were analyzed by X2 test. Results Most students (42/45) answered questions correctly in experimental group while only 30 of 44 students(30/44)did in control group(P<0.05). Concerning the results of investigation,PBL had more advantages than traditional teaching method in the following 5 aspects:self-studying ability(86.7%,39/45),clinical thinking ability(73.3%,33/45),information seeking ability (75.6%,34/45),expressing ability (82.2%,37/45),communicating between students (75.6%, 34/45)(P<0.05). Conclusions PBL has evident advantages in anesthesiology clinical demonstration. It can inspire students,cultivate abilities,enhance critical thinking and finally improve teaching effect.
