Study on the relationship between neutral alpha-glucosidase in seminal plasma and sperm motility

Abstract: The neutral alpha-glucosidase in seminal plasma were measured in 40 fertile males and 22 men who had small dosage injection (0.3-0.5ml/side) of Sodium Morrhuate (SM) via vas deferens into epididymis. Semen analysis was also measured in 20 semen Samples by HTM IVOS MOTILITY ANALYZER The results showed: 1. In fertile seminal plasma, neutral alpha-glucosidase activity is 23.31±15.31 mU/mL; In SM group, 4.46±3.79 mU/mL(P0.01)(?)2.There is correlativity between neutral alpha-glucosidase in seminal plasma and mean progressive velocity, mean linearity.R=0.9852.

Endoscopic anatomy research related to transsphenoidal optic nerve decompression

Abstract: Objective To investigate the anatomical relationship among optic nerve, posterior ethmoid sinus and ophthalmic artery to further provide surgical instruction for endoscopic transsphenoidal optic nerve decompression Method Messerklinger technique was adopted in eight cases of adult cadaveric head to expose the posterior ethmoid sinus and sphenoid sinus The optic-carotid recess and optic canal were identified The adjacent structure of optic canal was observed After removal of the bony wall of optic canal, the relationship between the optic nerve and the ophthalmic artery was disrupted Result the optic-carotid recess was observed in all specimens The occurrence of optic nerve prominence was 62% Three patterns of the syntropy of optic nerve were observed Optic nerve was border by posterior ethmoid sinus anteriorly and sphenoid sinus posteriorly in 8 cases (50%), by sphenoid sinus in 5 (31%), and by posterior ethmoid sinus in 3 (19%) At the cranial end, The ophthalmic artery was observed, 9 (56%) inferior-medially, 4 (25%) inferiorly and 3 (19%) inferior-laterally relative to optic nerve At the ophthalmic end, the artery was observed 3 (19%) inferiorly and 13 (81%) inferior-laterally relative to optic nerve Conclusion The optic-carotid recess can be regarded as the first landmark The ophthalmic artery injury should be avoided with regard to its relationship with optic nerve during endoscopic decompression surgery

A better long-term outcome in cardiac transplant recipient with a history of previous open heart operations.

Abstract: OBJECTIVE To investigate the effect of previous open heart operations (POHO) on the outcome of heart transplantation (HTX). METHODS Between November 1984 and May 1996, HTX was performed on 151 patients at Hartford Hospital. Among them, 61 patients had previous open heart operations (POHO) (group A), and 90 did not (group B). The average follow-up period was 1615 +/- 1185 days for group A and 1330 +/- 1125 days for group B. The recipient age was 55 +/- 10 years for group A and 48 +/- 12 years for group B (P < 0.01). There were 17 patients (26%) in group A and 14 (50%) in group B who were over 60 years of age. There was more coronary artery disease (74% versus 37%, P < 0.001) as etiology, and more diabetics in group A (P < 0.02). RESULTS The time for cardiopulmonary bypass (133 +/- 20 min versus 106 +/- 18 min, P < 0.01) and aortic clamp time (73 +/- 16 min versus 61 +/- 13 min, P < 0.01) were longer in group A. The operative mortality (within 30 days) was 0 and 2.2%, and the cumulative deaths were 16 (26%) and 43 (48%) respectively for group A and group B (P < 0.01). The causes of death were (group A vs group B): infection (31% vs 26%), rejection (13% vs 28%, P < 0.05), malignancy (25% vs 16%), cardiac event (6% vs 14%) and others (25% vs 16%). In patients over 60, there were 4 deaths (24%) in group A and 7 (50%) in group B. The difference was not significant. No patients died of rejection in this subgroup. The actuarial survival rates in group A versus group B were: 1 year, 93% versus 83%; 2 years, 85% versus 74%; 3 years, 81% versus 71%; 5 years, 76% versus 58%; and 10 years, 57% versus 24% (P < 0.01). CONCLUSION The survival rate in patients who had POHO is much higher than that in patients who had HTX as their primary operation.

A novel laparoscopic surgery simulator: System and evaluation

Abstract: A full-fledged surgery simulator should provide functions which really train and improve surgeonspsila skill. In this work, we comprehensively illustrate our surgery simulation system from its function, architecture and methods. Next, we evaluated our system from the doctorspsila perspective. Surveys are carried out to investigate doctorspsila experience of the system. Experiments are conducted to record their skill improvement during a certain period of time of training using our system. From the evaluation, some valuable points were concluded for future research direction.

A Multicenter, Randomized, Controlled Trial of Rebamipide Plus Lansoprazole for the Treatment of Postendoscopic Submucosal Dissection Ulcers.

Abstract: OBJECTIVES To evaluate the healing efficacy of rebamipide and lansoprazole combination therapy with lansoprazole alone for endoscopic submucosal dissection (ESD)-induced ulcers and clarify the ulcer healing-associated factors. METHODS Three hundred patients were randomized into control and experimental groups after they underwent ESD. The patients received intravenous pantoprazole (30 mg) every 12 hours and oral rebamipide (100 mg, experimental group) or placebo (control group) 3 times daily on days 1-3. On days 4-56, patients received oral lansoprazole (30 mg daily) and rebamipide (100 mg) or placebo 3 times daily. Endoscopic evaluations were performed at postoperative weeks 4 and 8. RESULTS At week 4, the ulcer reduction rate was significantly higher in the experimental than in the control group (0.97 ± 0.034 vs. 0.94 ± 0.078; P < 0.001). The ulcer healing (18.2% vs 20.3%; P = 0.669) and ulcer improvement rates (94.2% vs 88.7%; P = 0.109) in the 2 groups were not significantly different. At week 8, the ulcer healing and ulcer improvement rates were 90.6% and 100%, respectively, in both groups. Multivariate analysis showed that the combination treatment was an independent factor associated with ulcer area reduction after ESD. The maximum diameter of the initial ulcer (≥35.5 mm vs <35.5 mm) was an independent factor associated with the ulcer improvement rate after ESD. CONCLUSIONS The rebamipide and lansoprazole combination therapy can help accelerate the reduction rate of post-ESD ulcer compared with the lansoprazole monotherapy at 4 weeks of therapy.
