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]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

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.

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 ).

Objective The purpose of this study was to discuss the effect of visible light therapeutic equipment accompanied with electrolyzed-oxiding water (EOW) on pressure ulcer above the second phase. Methods We divided 44 patients with pressure ulcer above the second phase into the test group (23 cases, 28 spots) and the control group (21 cases, 25 spots). The test group received local decompression, debridement with EOW, exposure to visible light for 20 minutes, 10 times per day. The control group adopted local decompression, debridement with normal saline and local application of burn cream, 3 times per day. Results The effective rate of the test group was apparently higher than that of the control group (P<0.05). The healing time was also shorter than that of the control group (P<0.01). Conclusion Treatment of pressure ulcer above the second phase with visible light therapeutic equipment accompanied with electrolyzed-oxiding water proved to be an effective treatment method.

Objective:Whether extralevator abdominoperineal excision (ELAPE) improves survival and safety remains controversial.Systematic review of all comparative studies to define the superiority of ELAPE to conventional abdominoperineal excision (APE).Methods:Corresponding data,with case-control studies or cohorts regarding intraoperative perforation rate,the local recurrence rate and postoperative complications in the ELAPE group and the APE group,were retrieved from PubMed,Embase,the Cochrane Library,Chinese Biomedical Literature (CMB),VIP,China National Knowledge Infrastructure (CNKI),and Wanfang Database.Meta-analysis was performed by using RenMan 5.2.Results:A total of 10 articles were included.Intraperative perforation rate (MD=0.54,95％ CI 0.31 to 1.39,P=0.03),local recurrence rate (MD=0.30,95％ CI 0.21 to 0.42,P＜0.001) in the ELAPE group was significantly lower than that in the APE group.The difference in positive margin rate between the 2 groups was not statistically significant (P=0.07).Conclusion:Through gap repair of episiotomy and individualized therapy can improve ELAPE postoperative quality of life.ELAPE shows certain advantages in treating lower rectal cancer comparing to APE,but it should pay attention to individualized treatment.More studies through large sample multi-center,medium and long term randomized design are necessary to determine the effect of surgery on tumor.
