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.

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

[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.

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 To quantitatively assess the regional myocardial function in the patients with heart failure by tissue Doppler imaging. Methods The apical 4 chamber, 2 chamber and long axis view of two-dimensional tissue Doppler imaging were acquired in 30 healthy individuals and 18 patients with heart failure by GE Vivid 7 commercially machine.The basal and middle segments in left and right ventricle were analyzed in tissue velocity imaging model. The following cardiac intervals and velocities were measured in each segment, including the isovolumetric contraction time(IVCT), the ejection time, the isovolumetric relaxation time(IVRT); the rapid filling time, the artrial systolic time, the peak velocity and acceleration of Sm, the peak velocity and acceleration of Em, and the peak velocity and acceleration of Am. Results Compared with control group, IVCT, IVRT and atrial contraction time were prolonged, the ejection time and rapid filling time were shorterned, peak velocity and acceleration of Sm, Em, and Am were reduced in heart failure group. Conclusions There were characteristic changes on tissue velocity imaging in the patients with heart failure which include the delay of IVCT and IVRT and reduction of velocity in Sm, Em, and Am.

UNLABELLEDABSTRA CT OBJECTIVE To compare the complications and clinical outcome of titanium elastic nail (TEN) versus plate-screw fixation (PF) for the treatment of upper segment fractures of femoral shaft in children.

METHODSFrom May 2006 and August 2012,32 consecutive children with upper segment fractures of femoral shaft were studied prospectively. They were randomly divided into TEN group and PF group. Ninteen patients were treated with titanic elastic nail (TEN) fixation including 11 males and 8 females with an average age of (6.9?2.2) years old ranging from 3 to 11,11 cases of them were type A, 6 cases were type B,2 cases were type C according to AO classification. The other 13 patients were treated with plate-screw fixation (PF) including 9 males and 4 females with an average age of (7.5±2.1) years old ranging from 5 to 12 years, and 3 cases of them were type A,6 cases were type B,2 cases were type C. Operative time, blood loss,incision length,the time of hospitalization,fracture healing time, postoperative complications and function recovery between two groups were compared and evaluated.

RESULTSThe average follow-up period of the patients was 25.3 months (ranging from 15 to 48 months) in TEN group, and 36.2 months (ranging from 13 to 36 months) in the PF group. The operation time, time of hospitalization, the time of implants removed after the initial surgery, fracture healing time in TEN group were respectively (56.7±11.2) min, (6.6±3.9) d, (8.1±2.3) months, (12.6+3.8) weeks; and in PF group were respectively (51.5±8.3) min, (7.8±4.8) d, (7.8±1.6) months, (11.8±2.8) weeks, there was no significant difference between two groups (P>0.05). However, the length of incisions was (4.3±1.7) cm and the intraoperative blood loss was (12.7+3.2) ml in TEN group,which were significantly less than that in PF group respectively (89.2±21.1) ml and (11.6?2.3) cm (P<0.05). There was no statistically difference in postoperative in complication between two groups, but the patients in TEN group had a higher incidence of soft tissue irritation and misalignment. Outcome scores according to Sanders had no significant difference between two groups (P>0.05). In TEN group,the result was excellent in 13 cases, good in 3,fair in 2, and poor in 1, while in PF group excellent in 10, good in 2, fair in 1.

CONCLUSIONThere is no significant difference in therapeutic effects between TEN and PF for children with upper segment fractures of femoral shaft. The internal fixation should be selected according to the associated fracture type, weight, the expected value of the parents, scars, and so on.
