BACKGROUND: The application of polymerized 2-hydroxyethyl methacryate (PHEMA) in many organs of living body shows good biocompatibility.OBJECTIVE: To observe the biocompatibility and fibrovascular condition of methl-methacrylate (MMA) modified PHEMA hydrogel orbital implant.DESIGN: Single sample observation.SETTING: Department of Ophthalmology, the General Hospital of Chinese PLA; Institute of Polymer Science,Department of Chemical Engineering, Tinghua university.MATERIALS: Twenty-five New Zealand rabbits of either gender and clean grade, weighing 2.0 to 2.5 kg, were provided by the Animal Experimental Center, General Hospital of Chinese PLA. The animals were observed at postoperative 2, 4,8, 12 and 24 weeks, 5 at each time point. The experiment was permitted by ethics committee. MMA modified PHEMA hydrogel orbital implant was provided by Institute of Polymer Research, Department of Chemical Engineering, Tinghua University. The experiment was permitted by ethics committee.METHODS: This experiment was carried out in the laboratory of Department of Ophthalmology, the General Hospital of Chinese PLA from March to October 2003. The right eye served as operation eye. When the rabbits were anesthetized,their eyelids were open with eyelid retractor. Bulbar conjunctiva was open along the edge of limbus of cornea for isolating fascia. Oculorotatory muscle was isolated and pre-set suture line was made, then muscle was cut off. When optical nerve was cut off, eyeball was completely excised. A MMA modified PHEMA hydrogel orbital implant with the diameter of 14 mm was implanted into the fossa orbitalis of rabbits. Single photon emission computed tomography (SPECT) was performed at postoperative 2, 4, 8, 12 and 24 weeks. The hydrogel orbital implant was taken out at postoperative 2, 4, 8,12 and 24 weeks for light microscope, immunohistochemical and electron microscope examinations.MAIN OUTCOME MEASURES: Vascularization of hydrogel orbital implant was observed in vivo by isotope tracing observation at different time points. Vascularization of hydrogel orbital implant was observed ex vivo by light microscope,immunohistochemical and electron microscope observations.RESULTS: All 25 New Zealand rabbits were involved in the final analysis. ①SPECT examination showed that isotope increased around the implants at week 2, and extended gradually at weeks 4 and 8. The radiotracer accumulated evenly in the implants from surrounding to the center at week 12. ②Light microscopic examination of the prostheses revealed fiber vessels grew from the surrounding to the center. At week 2,fibrovascular tissue grew in the hole of implant. Long or round cells with deeply dyed nucleuses were found in the hole, being fibroblasts. The vascular structure in the hole of the implant was clear, and vascular wall and blood cells were found. The inflammatory cells were mainly neutrophils and lymphocytes, and occasionally large macrophages. ③Scanning electron microscope showed that fibrovascular tissue grew in the hole of the implant, and was dense and intercrossed at week 12. ④ Conjunctiva split appeared postoperatively in 1 of 25 cases, and healed well after two times of operation. Conjunctival congestion lessened and conjunctiva healed within postoperative 7 days in the remaining 24 animals.CONCLUSION: MMA modified PHEMA hydrogel orbital implant has good histocompatibility and fast vascularization process, and is easy to be operated with fewer complications. So, it is a safe and practicable new type orbital implant.

Objective To investigate which is better for gastroduodenal endoscopic ultrasound (EUS) between right lateral position and left lateral position of patients guided by nurses. Methods A total of 79 patients were randomly assigned to the left and right lateral position groups. Each patient received EUS examination in three parts, which were sinuses ventriculi, duodenal bulb and descendant duodenum. The operating time and the water volume of each patient were recorded in the procedure of EUS. Results Operating time in sinuses ventriculi, duodenal bulb and descendant duodenum of left lateral position group was (9.0±4.0) min, (6.5±3.2) min and (13.6±10.9) min, while (5.7±3.0) min, (3.6± 1.7) min and ( 6.6±5.7) min in right lateral position group, the differences were significant (t=3.098, 2.190, 3.210, P<0.05) . In the meantime, water volume was (892.0±169.5) ml, (898.6±145.9) ml and (1 012.0± 333.2) ml in sinuses ventriculi, duodenal bulb and descendant duodenum of left lateral position group, while (327.1±79.3) ml, (260.6±30.4) ml and (263.8±17.7) ml in three parts of right lateral position group, respectively. Significant differences were found in water volume among subgroups (t=13.798, 11.290, 4.930, P<0.01 or 0.05). Conclusions In the process of EUS for submucosal lesions at gastric antrum and duodenum, right lateral position instructed by nurses can shorten the operating time and make the procedure easier. This might reduce risks of regurgitation, aspiration, and other related complications.

OBJECTIVETo investigate the therapeutic effect of reconstruction of facial defects with frontal expanded flaps bipedicled by superficial temple vessels and supraorbital/supratrochlear neurovascular bundles.

METHODSFrom June 2006 to Mar. 2013, the patients with mostly unilateral facial defects which affected temple area and crossed the facial midline, were treated with frontal expanded flaps. The expanders were implanted at first stage and the expanded frontal flaps were transferred at second stage. At third stage, pedicle division was performed and the pedicle skin tissue was used to repair the residue defect.

RESULTAll the 18 flaps survived completely with satisfactory color and texture. Good results were achieved during the follow-up period of one year.

CONCLUSIONThe bipedicled frontal expanded flap has a reliable blood supply which is very suitable for large facial defect.

Objective: To study left ventricular diastolic function (LVDF) in patients with coronary artery disease(CAD) by tissue Doppler imaging (TDI) and color Doppler echocardiography. Methods: The maximum velocity ( V max ) and time velocity integration(TVI) in early and late diastolic stage of mitral valve orifice of 80 patients with CAD and 79 normal subjects were measured by color Doppler echocardiography at apical 4 chamber view. Meanwhile, the V max and/or TVI of the myocardial motion spectrum of left ventricular lateral wall near the mitral valve annulet were measured by TDI. These data were compared and analysed by statistical method. Results: In the normal subjects, the older the subject, the lower the V max and TVI of early diastolic stage, the higher the V max and TVI of late diastolic stage. In CAD group, changes were not associated with ages and were affected by the degree of the myocardial pathology. The LVDF couldn't be exactly judged by color Doppler echocardiography when pseudonormalization blood flow spectrum appeared, but TDI technique was relatively sensitive. Any regional myocardial motion could be measured by TDI according to the examiner's design. Conclusion: LVDF by color Doppler echocardiography is simple and convenient. TDI technique can be used for determining overall LVDF and left ventricular systolic function. [
