AIM: The effects of ZX-5, as nitric oxide (NO) donor, on ocular blood flow has been investigated using colored microsphere technique in previous study. The relationship between the production of NO by ZX-5 and ocular blood flow has been evaluated. ZX-5 has been shown to have strong positive effect on increasing choroidal blood flow. However,the effect of ZX-5 on retinal function recovery, the effects of its optical isomers, (R, R)-ZX-5 and (S, S)-ZX-5, on choroidal blood flow and retinal function recovery have not been studied and merit investigation.METHODS: Colored microsphere technique was used for in vivo experiments to determine choroidal blood flow of ocular hypertension (40mmHg) in rabbit eyes. Electroretinography was used to measure the b-wave recovery as an indication of retinal function recovery.RESULTS: (R, R)-ZX-5 increased choroidal blood flow at 10g/L, 50μL instillation into eyes at all time points (P<0.05).(S, S)-ZX-5 was not effective in increasing choroidal blood flow. ZX-5 and (R, R)-ZX-5 showed significant effects in retinal function recovery after ischemia of the retina at all time points (P<0.05); whereas (S, S)-ZX-5 did not show significant effect on recovery of b-wave after ischemia at most time points except at 120 and 240 minutes.CONCLUSION: ZX-5 and (R, R)-ZX-5 have high potency in increasing the choroidal blood flow and improving the retinal function recovery. It is hoped that they could be used for the prevention/treatment of ocular blood flow related eye diseases.

BACKGROUNDPseudoaneurysms (PAs) are common vascular abnormalities predominantly arising from a disruption in the integrity of the arterial wall. The potential complications of PAs are usually unpredictable and carry high rates of morbidity and mortality. This paper presents our experience with various treatment strategies for PAs.
METHODSFifty-four patients with 55 PAs were diagnosed by non-invasive imaging examination. The etiology of PAs included trauma (33/55), infection (5/55), iatrogenic (6/55), and idiopathic (11/55). Different procedures including ultrasound (US)-guided compression, endovascular treatment, and surgery were performed depending on the location of PAs, size of the sac and neck, and characteristics of the donor artery. The methods of endovascular treatment included embolization of parent artery, the PA sac, or implantation of a stent-graft. Follow-up was performed using US or CT and ranged from 1 day to 24 months (average 16.7 months).
RESULTSIn all 54 patients, 3 patients with superficial PAs were treated by US-guided compression, while 44 patients with 45 PAs located in the head and neck (n = 20), viscera (n = 10) or extremities (n = 15) were treated by endovascular treatment. Nine patients with PAs located in the head and neck (n = 2) or extremities (n = 7) were treated by surgery. Among them, one patient underwent endovascular treatment combined with surgery and 1 was treated by surgery after unsuccessful US-guided compression. In the 3 patients treated with US-guided compression, 2 were successfully treated while the remaining patient required additional surgery. Primary technical success of endovascular management was 97.7% (43/44) and the cure rate was 95.5% (42/44). In the surgery group, 4 patients recovered well, 1 patient was cured by endovascular treatment combined with surgery, 2 cases underwent amputation, 1 patient died of multi-organ failure and 1 patient was paralysed.
CONCLUSIONSMinimally invasive interventional techniques are established treatment methods for PA with favorable success rates and minimal morbidity. The therapeutic options should be tailored to the location, size and rupture risk of PA, condition of the donor artery and existing comorbidity.

OBJECTIVE:
To study the characteristics and biomechanical mechanism of riding injuries involving bicycles collided by motor vehicles.
METHODS:
The real traffic accident cases of bicycles collided by motor vehicles, including the information of scenes, bicycles, motor vehicles, rider wounds and traffic directions, were collected. Retrospective method was used to study these riding injuries. In addition, typical cases were selected to simulate traffic accident courses with computer simulation software, and the dynamic data like acceleration, force, moment were cxtracted to compare with those in the real cases.
RESULTS:
There were no difference of occurring frequency between cases with or without riding injuries, as well as between one-side-collision and front- or back-collision. The riding injuries seemed less in accidents involving large-scale vehicles. The frequency of riding injuries increased with vehicle speed. The wound location was low on collision side and high on opposite.
CONCLUSION
Analysis of riding injury characteristic in traffic accidents and their biomechanical mechanism would be helpful for estimation of traffic manner.

OBJECTIVE:
Using computer simulation to analyze the effects of speed, type of automobile and impacted position on crash-course and injuries of pedestrians in automobile vs. pedestrian accidents.
METHODS:
Automobiles (bus, minibus, car and truck) and pedestrian models were constructed with multi-body dynamics computing method. The crashes were simulated at different impact speeds (20, 30, 40, 50 and 60 km/h) and different positions (front, lateral and rear of pedestrians). Crash-courses and their biomechanical responses were studied.
RESULTS:
If the type of automobile and impact position were the same, the crash-courses were similar (impact speed < or = 60 km/h). There were some characteristics in the head acceleration, upper neck axial force and leg axial force.
CONCLUSION
Multi-body dynamics computer simulation of crash can be applied to analyze crash-course and injuries (head, neck and leg) of pedestrians.
