Objective To investigate the relationship of clinical indexes between retinopathy in systemic-lupus-erythematosus （SLE）nephritis and SLE，and to discuss its clinical significance. Method The clinical data of 43 cases of SLE nephritis with ocular fundus diseases were retrospectively analyzed.The relationships between retinopathy and kidney defect，general lesions，SLEDAI grade，antinuclear antibody （ANA），anti-double stranded DNA，complement 3 and antiphospholipid antibodies were analyzed with Logistic regression respectively. Results In 86 eyes of the43paitents，there were retinal cotton wool spots in51eyes（59.3%），edema of optic disk in 43 eyes（50.5%），retinal haemorrhage in 12 eyes（14.0%），retinal artery occlusion in 5 eyes（5.8%），central retinal vein occlusion in 2 eyes（2.3%），retinal detachment in 3 eyes（3.5%），optic atrophy in 2 eyes（2.3%），and neovascularization in 2 eyes（2.3%）.Logistic regression analysis revealed that SLEDAI grade had linear dependent relation with cotton wool spots and optic disk edema（chi;2=42.154，6.498;P＜0.001），and didnrsquo;t have any correlation with proteinuria，hematuria and kidney function.Linear relation between retinal vascular occlusion and antiphospholipid antibodies was found（chi;2=24.475，P＜0.001）.Retinal haemorrhages，retinal detachment，optic atrophy and neovascularization did not correlate with clinical features. Conclusion SLEDAI grade had linear dependent relation with cotton wool spots and optic disk edema in patients with SLE nephritis，and Linear relation between retinal vascular occlusion and antiphospholipid antibodies is ascertained. Ocular fundus diseases are clinically important for evaluating the therapeutic responses and prognosis in lupus nephritis. (Chin J Ocul Fundus Dis, 2006, 22: 239-241)
Objective To observe the clinical features and treatment outcomes of presumed tubercular retinal vasculitis. Methods This is a retrospective non-comparative interventional clinical research. A total of nine patients (11 eyes) with major presentation of retinal vasculitis were included in this study. Patients first consulted the eye clinic and were diagnosed presumed tubercular retinal vasculitis. The patients, seven males and two females, aged from 19 to 66 years, with an average of 43.89 years. The time interval from symptoms to diagnosis ranged from two weeks to six months with an average of 76.27 days. Visual acuity, slit lamp ophthalmoscopy, fundus fluorescein angiography (FFA), optical coherence tomography (OCT), hematological and tuberculosis related investigations were examined and analyzed. All patients had standard anti-tuberculosis treatment. Treatment outcomes were followed for six to 37 months with an average of 14.11 months. Results Baseline visual acuity ranged from hand movement to 0.8 with an average of 0.28. Among 11 eyes, six presented mild to moderate vitritis, five presented as retinal vein occlusion with no obvious vitirits. Fundus examination showed six cases with retinal hemorrhage, four cases with macular edema, two with macular epiretinal membrane, and two with vitreous hemorrhage. FFA revealed 11 cases with leakage of vessels, 11 with nonperfusion area, four with macular edema, three with retinal neovascularization, and two with choroidal lesions. OCT of nine eyes suggested six eyes with retinal edema, three with macular edema, three with macular epiretinal membrane. TST of seven patients were all b positive. T-SPOT.TB of four patients were all positive. Three of eight patients who had chest X-ray or chest CT were suggested tuberculosis infection. Four to six weeks after the start of anti-tuberculosis treatment, vitritis, exudates, retinal and macular edema subsided. During follow up, inflammation was stable with no recurrence observed. The visual acuity of last follow-up ranged from 0.15 to 0.8 with an average of 0.51. Conclusions The main presentations of presumed tubercular retinal vasculitis are vitritis, retinal vein occlusion, and retinal hemorrhage. Standard anti-tuberculosis treatment can improve inflammation and retinal hemorrhage.
Objective To observe the incidence of ciliary detachment and its relationship with intraocular hypotension soon after vitrectomy. Methods A total of 46 eyes of 46 patients who underwent vitrectomy were examined by ultrasound biomicroscope (UBM). The patients were divided into three groups according to different tamponade: gas group (11 eyes), silicone oil group (8 eyes) and balanced saline solution (BSS) group (27 eyes). Basing on the postoperative intraocular pressure (IOP), the patients were divided into two groups: IOPlt; 10 mm Hg (25 eyes) and IOPge;10 mm Hg (21 eyes). UBM was applied to determine the tomographic features of the ciliary body 3 days after the surgery. IOP were monitored by noncontact tonometer daily after the surgery. The eyes with ciliary detachment were then examined once a week till the ciliary detachment reattached. The followup period was from 14 to 35 days. Results After vitrectomy, ciliary detachment was observed in 20 eyes of 46 eyes (43.5%), The incidence of ciliary detachment was 27.3％ in gas group, 25.0％ in silicone oil group, and 55.6％in BSS group. The average IOP in eyes with ciliary detachment ［(6.47plusmn;4.49) mm Hg （1 mm Hg=0.133 kPa）］ was significantly lower than that in the eyes without ciliary detachmen ［(15.61plusmn;7.72) mm Hg］ (t=8.031,Plt;0.001). The incidence of ciliary detachment was higher in eyes with postoperative IOP lt;10 mm Hg (68.0％) than that in the eyes with postoperative IOP ge;10 mm Hg (14.3%) (chi;2＝15.60, Plt;0.001). All eyes with postoperative ciliary detachment got spontaneous reattachment within 30 days after the surgery except that one eye had optic disc edema due to severe intraocular hypotension. Conclusions Early postoperative ciliary detachment is a common complication after vitrectomy. Eyes filled with BSS have the highest incidence of postoperative ciliary detachment. Most of the patients with ciliary detachment may get spontaneous reattahment within 30 days after the surgery.
Abstract： Objective To summarize the clinical experiences of performing extracorporeal membrane oxygenation (ECMO) on patients with heart and respiratory failure, and compare the clinical outcomes of Medtronic system and Quadrox PLS system. Methods We retrospectively analyzed the clinical data of 121 heart and respiratory failure patients who underwent ECMO treatment in Fu Wai Hospital from December 2004 to December 2009. Based on the different systems used, 121 patients were divided into two groups. In group M, there were 65 patients including 41 males and 24 females, with an age of 26.6±25.9 years; and they accepted Medtronic ECMO system treatment. In group Q, there were 56 patients including 39 males and 17 females, with an age of 32.4±23.9 years and they underwent Quadrox PLS ECMO system treatment. The evaluation of the clinical outcomes of these two different systems was based on the comparison of transmembrane pressure drop (TMPD), anticoagulation, hemolysis, plasma leakage, organ function, complication and hospital mortality between the two groups. Results Compared with group M, ECMO with Quadrox PLS system was associated with lower TMPD (at the beginning of ECMO: 15.0±6.0 mm Hg vs.28.0±5.0 mm Hg, P=0.000; 24 hours later: 16.0±5.0 mm Hg vs. 30.0±7.0 mm Hg, P=0.000) and less thrombus formation(7.1% vs.23.1%, P=0.037), less plasma leakage (0.0% vs. 50.8%, P=0.000), less hemolysis (14.3% vs. 29.2%, P=0.047). There were no significant differences between the two groups in support duration, complication rate, and hospital mortality(Pgt;0.05). Conclusion Both devices have similar effects for safe clinical application, but Quadrox PLS ECMO system has a relatively high biocompatibility with lower TMPD, less plasma leakage, and thrombus formation.
Objective To observe and analysis the features of images of fundus fluorescein angriography (FFA) in low-perfused retinopathy caused by cephalo-cervical peripheral vascular stenosis or occlusion. Methods The results of FFA of 27 patients diagnosed with carotid artery stenosis or occlusion by digital subtraction angiography (DSA) and examination of Doppler and vascular-pulsation were retrospectively analyzed. Result All of the patients had a delayed arm-retinal circulation duration from 20.0 to 81.08 seconds with the mean of 32.1 seconds; a delayed retinal arteriovenous filling duration from 6 to 64.0 seconds with the mean of 24.2 seconds. Delayed arm-retinal circulation duration and retinal a rteriovenous filling duration in 10 cases (37.0%); microangioma, vascular wall staining, nonperfused capillary area in 11 (40.7%); and anterior ischemic syndrome in 6 (22.2%) were found. In the 6 patients with anterior ischemic syndrome, 4 cases had narrow retinal artery, segmental changes of blood stream, vascular atresia, and abnormal arterio-venous anastomosis, and 2 cases had bold vascular loops. Conclusions The main manifestations of FFA in patients with low-perfused retinopathy are malperfusion and retinal ischemia, whose degrees relate to the extend of carotid artery stenosis or atresia, and the process of the disease.Serious retinal ischemia may combined with anterior ischemic syndrome.

Objective To determine the expression of the growth factors and the receptors related to angiogenesis in the intraocular tissues incarcerating in the sclerotomy sites. Methods Ten specimens from prolapsing intraocular tissues in sclerotomy sites during vitrectomy were obtained and serially sectioned in cryostate and were stained with a group of polyclonal antibodies against vascular endothelial growth factor(VEGF), basic fibroblast growth factor (bFGF), platelet-derived growth factor-A(PDGF-A) and transforming growth factor-β1(TGF-β1) as well as their receptors by using a streptavidin peroxidase system. Results The tissues prolapsed from the sclerotomy sites were identified as retina(3 cases), vitreous tissues(3 cases), degenerated red blood cell components(2 cases), ciliary body(one case) and fibrous tissue(one case). All specimens expressed VEGF and bFGF as well as their receptors. PDGF-A, TGF-β1 and their receptors expressed in the most of specimens. The positive cells included retinal cells, ciliary non-pigmented epithelial cells and pigmented epithelial cells, fibrous cells and the cells in vitreous. Conclusions The intraocular tissues incarcerated in the sclerotomy entries express the growth factors and receptors related to angiogenesis. This might be one of the potential factors of developing anterior proliferative vitreoretinopathy. (Chin J Ocul Fundus Dis, 2002, 18: 34-37)
Abstract: Objective To evaluate the prediction validation of European system for cardiac operative risk evaluation （EuroSCORE） in prolonged intensive care unit (ICU) stay, mortality, and major postoperative complications for Chinese patients operated for acquired heart valve disease. Methods Between January 2004 and January 2006, 2 218 consecutive patients treated for acquired heart valve diseases were enrolled in Fu Wai Hospital. All these patients accepted valvular surgery. Both logistic model and additive model were applied to EuroSCORE to evaluate its ability in predicting mortality, prolonged ICU stay and major postoperative complications of patients who had undergone heart valve surgery. An receiver operating characteristic curve（ ROC) area was used to test the discrimination of the models. Calibration was assessed by HosmerLemeshow goodnessoffit statistic. Results Discriminating abilities of logistic and additive EuroSCORE algorithm were 0.710 and 0.690 respectively for mortality, 0.670 and 0.660 for prolonged ICU stay, 0.650 and 0.640 for heart failure, 0.720 and 0.710 for respiratory failure, 0.700 and 0.740 for renal failure, and 0.540 and 0.550 for reexploration for bleeding. There was significant difference between logistic and additive algorithm in predicting renal failure and heart failure (Plt;0.05). Calibration of logistic and additive algorithm in predicting mortality, prolonged ICU stay and major postoperative complications were not satisfactory. However, logistic algorithm could be used to predict postoperative respiratory failure (P=0.120). Conclusion EuroSCORE is not an accurate predictor in predicting mortality, prolonged ICU stay and major postoperative complications, but the logistic model can be used to predict postoperative respiratory failure in Chinese patients operated for acquired heart valve diseases.
Objective To observe the clinical characteristics and therapeutic effects of carotid artery stenosisrelated ocular ischemic appearance(OIA).Methods The clinical data of 210 patients of carotid artery stenosis (81 of them with OIA) were retrospectively reviewed. They were diagnosed by color doppler image（CDI）or digital subtraction angiography (DSA),and had undergone medicine,carotid artery stenting (CAS)and carotid endarterectomy (CEA). Of 81 patients with OIA,49 patients (60.49%) with OIA only, 32 patients（39.51%）with ocular ischemic disease (OID).24/32 OID patients received ophthalmic treatment such as retinal laser photocoagulation and anti glaucoma therapy (drugs and cyclocryotherapy). Results The ocular manifestations of 81 OIA patients included transient amaurosis in 38 cases (47.14%),flash before the eye in 30 cases (36.67%), periorbital swelling and pain in 28 cases (34.57%), diplopia in 11 cases (13.58%) and vision loss in 9 cases (11.11%). The ocular manifestations of 32 OID patients included ischemic optic neuropathy in 9 cases (28.13%), ocular ischemic syndrome in 6 cases (18.75%), central or branch retinal artery occlusion in 6 cases (18.75%), retinal hemorrhage in 5 patients (15.62%)，extraocular muscle paralysis in 4 patients (12.50%) and neovascular glaucoma in 2 patients (6.25%). The higher the degree of carotid stenosis,the higher incidence of ocular ischemic disease,there was highly positive correlation between each other (R=0.837, P＜0.05).The total effective rate of carotid artery stenting and carotid endarterectomy was significantly higher than drug treatment alone (t=2.73, 3.14; P＜0.01). Conclusion The ocular manifestations of carotid stenosis related ocular ischemic appearance can be transient amaurosis, eyes flashing,eye redness,periorbital pain, diplopia and decreased visual acuity.The ocular manifestations of carotid stenosisrelated ocular ischemic disease can be ischemic optic neuropathy, ocular ischemic symptoms, central or branch retinal artery occlusion and neovascular Carotid artery stenting and carotid endarterectomy are more effective than drug treatment alone for those patients.
Objective To study the prevention and management of early compl ications associated with anterior cervical spinal surgery. Methods From November 1998 to December 2006, 363 cases were treated with anterior cervicalsurgery, including 268 males and 95 females aged 17-79 years．In these cases, 224 suffered from cervical spondylosis, 39 from cervical disc herniation, 87 from cervical trauma, 9 from cervical tumor and 4 from cervical tuberculosis. Forty-eight cases with anterior cervical surgery were fused by autogenous il iac bones, 132 cases with anterior cervical surgery were fused by autogenous il iac bones and anterior cervical spine locking plates, and 183 cases with anterior cervical surgery were fused by titanium mesh cage and anterior cervical spine locking plates. Results A total of 282 cases were followed up for 3 months to 5 years with the average of 1 year and 11 months. Twenty-three compl ications associated with surgery were found, with an incidence of 8.16%. Three cases of transient superior laryngeal nerve palsy recovered within 3-7 days after the restriction of l iquid diet and fluid replacement. Two cases of recurrent laryngeal nerve palsy recovered by 3-month pronunciation practice. One case of spinal cord injury was treated with medicine for dehydration and anti-inflammation, and was restored to preoperative muscle power of inferior extremity after 6 months. Two cases of CSF leakage were cured with moderate local compression and meticulous water-tight wound closure. Among the 10 patients with compl ications of internal fixation, one suffering mild dysphagia was reoperated, while the others were treated with cephal-cervico-thorax plaster external fixation and recovered with sol id fusion within 3-18 months. Among the 4 cases with cervical hematoma, 1 died of wrong rescue procedures and 1 was infected. Conclusion Adequate preoperative preparation, thorough understanding of anatomy related to the anterior approach and skilled surgical technique are essential for preventing the early postoperative compl ications of anterior cervical spinal surgery．
