Objective To summarize the visual outcome of patients with severe ocular trauma treated with vitreous surgery. Methods Clinical data of 188(191 eyes) with severe ocular trauma treated with vitreous surgery in a period from November 1996 to April 1998 were analysed retrospectively. Results The study included penetrating injury in 56 eyes, foreign bodies in the posterior segment in 70 eyes, blunt injury in 41 eyes , and globe rupture in 24 eyes. Main complications included endophthalmitis in 35 eyes, choroidal bleeding in 20 eyes, retinal detachment in 60 eyes, and vitreous hemorrhage in 97 eyes. Post-opera-tively, out of 188 eyes, except for 3 of patients too young to examine, visual acuity improved in 133(70.7%), including 85(45.2%) with visal acuity 0.02-1.0, 46(24.5%) remained unchanged; and 9(4.8%) had worse vision. Among 34 with no-light-perception, 12 had light-perception or over. Conclusion A majority of severe trauma eyes can be salvaged with considerable visual recovery after adequate and timely vitreous surgery. (Chin J Ocul Fundus Dis,1999,15:4-6)
ObjectiveTo investigate the clinical characteristics and prognosis of cerebral hemorrhage in young and elderly patients, to provide evidences for individual clinical diagnosis and treatment, and lay a foundation for building a predictive model of prognosis in cerebral hemorrhage.MethodsPatients with spontaneous cerebral hemorrhage in the Third People’s Hospital of Chengdu were recruited prospectively and continuously from January 2014 to January 2019. They were divided into the youth group (≤50 years old) and the elderly group (>50 years old), and their risk factors, disease characteristics, etiology, and prognosis were analyzed.ResultsA total of 757 patients were recruited. There were 160 cases (21.1%) in the youth group, including 120 males and 40 females, aged from 17 to 50 years, with an average age of (42.06±7.62) years old; 597 cases (78.9%) in the elderly group, including 361 males and 236 females, aged from 51 to 96 years, with an average age of (69.34±10.56) years old. The incidences of hypertension (74.2% vs. 51.2%), diabetes (15.1% vs. 4.4%), coronary heart disease (12.1% vs. 1.3%), and the level of blood glucose at admission [7.1 (5.8, 8.4) vs. 6.3 (5.3, 8.1) mmol/L] in the elderly group were higher than those in the youth group (P<0.05), respectively. However, the proportions of males (60.5% vs. 75.0%), smoking (24.5% vs. 36.9%), and the diastolic blood pressure at admission [(92.37±18.50) vs. (100.95±25.25) mm Hg (1 mm Hg=0.133 kPa)] in the elderly group were lower than those in the youth group (P<0.05), respectively. There was no significant difference between the two groups in systolic blood pressure at admission, Glasgow Coma Score, National Institutes of Health Stroke Scale score, initial hematoma volume, hematoma enlargement, brain hernia, location of hemorrhage, midline shift, hydrocephalus, combined subarachnoid hemorrhage, or intraventricular extension (P>0.05). Hypertension was the most common etiology in the two groups. There was a significant difference in the etiology of cerebral hemorrhage between the two groups (P<0.05), the difference was mainly reflected in cerebral amyloid angiopathy, cavernous hemangioma, and arteriovenous malformation. The fatality rate during hospitalization (9.4% vs. 20.9%), 3 months after discharge (10.3% vs. 26.3%), and at 1 year follow-up (19.0% vs. 37.6%) in the youth group was lower than that in the elderly group (P<0.05), respectively. The disability rate 3 months after discharge and at 1 year follow-up in the youth group was lower than that in the elderly group (32.1% vs. 44.2%, 16.9% vs. 34.4%; P<0.05), respectively.ConclusionsThe education of healthy lifestyles should be strengthened to reduce the adverse effects of smoking in young patients. Young patients should choose antihypertensives that can control diastolic blood pressure better. There are more structural abnormalities in young patients, so routine vascular examination is reasonable. It is necessary to focus on whether the original underlying diseases are stable in elderly patients. Cerebral amyloid angiopathy is an important cause of cerebral hemorrhage in elderly patients, and is a risk factor of recurrence. Anticoagulation or antiplatelet therapy should be cautious.

Peripheral exudative hemorrhagic chorioretinopathy (PEHCR) is a peripheral retinal disease characterized by subretinal hemorrhage and/or subretinal pigment epithelial hemorrhage or exudation. It is often misdiagnosed as age-related macular degeneration, polypoidal chorioretinopathy or choroidal melanoma. With the development of multimodal imaging, PEHCR has different features under different examinations, such as B-scan ultrasound, fluorescein fundus angiography, optical coherence tomography and so on, which contributes to differention from other diseases. Clinical treatments for the disease include intravitreal injection of retinal photocoagulation therapy, anti-vascular endothelial growth factor, pars plana vitrectomyand so on, but there is still no universal consensus. In order to gain a deeper understanding of the clinical features, treatment options and prognosis of PEHCR, minimize missed diagnoses and misdiagnoses, and improve treatment efficiency, further research is required.
Objective To explore the causes and treatment of rebleeding after operation on portal hypertension patients. Methods The clinical data of 41 rebleeding cases underwent the operational between January 2000 and December 2009 in Peking Union Medical College Hospital were retrospectively analyzed. Results All 13 cases who got rebleeding after shunt operation received lienectomy, but for those who got rebleeding after lienectomy, 23 patients received Phemister or modified Phemister or expanded lienectomy and 5 patients received shunt operation. Surgical related complications occurred in 7 cases (17.1%) at 2 weeks after operation, including abdominal bleeding (3 cases), gastrointestinal bleeding (2 cases), and intractable ascites (2 cases). After the follow-up of 3-60 months (mean 39 months), all patients were still alive. During the follow-up, 3 cases of recurrent esophageal varices were observed and one of them got rebleeding.Conclusion The majority of rebleeding after lienectomy tend to be ascribed to the wrong operations chose, while bad operation skill often contribute to the rebleeding after shunt operation, suggesting ideal therapeutic effect for rebleeding can benefit from appropriate operation choose.
摘要:目的:动态观察大鼠脑出血后血肿周围组织补体激活与细胞凋亡的规律。方法:用胶原酶注入到大鼠尾状核的方法制作脑出血模型。将大鼠分为脑出血、假手术组、正常组3组。采用苏木素伊红(HE) 染色、免疫组织化学染色及原位末端脱氧核苷酸转移酶介导的dUTP 缺口末端标记法(TUNEL)分别观察各组在脑出血后第6 h、12 h、24 h、48 h、72 h、5 d、7 d时血肿周围补体C3、促凋亡基因(Bax)、抑凋亡基因(Bclxl)及TUNEL的表达。结果补体C3的表达峰值在24~48 h;TUNEL、Bax蛋白表达术后12h增加,48~72 h达高峰,而Bclxl蛋白表达高峰在48h。结论:大鼠脑出血后血肿周围组织补体C3的表达增加与细胞凋亡的演变趋势一致,C3与凋亡有相关。Abstract: Objective: To study the complement activation and apoptosis regular genes changes in the tissues of the perihematoma of intracerebral hemorrhage (ICH) in rats. Methods: Intracerebral hemorrhage was induced in rats by injection of bacterial collagenase into the caudate nucleus. Histopathological changes were studied in 6 h,12 h, 24 h, 2 d, 3 d, 5 d, 7 d after the injection. The immunohistochemistry and TUNEL analysis were performed. The expression of complement factor C3, the TUNELpositive cells, the proapoptotic gene expression (Bax) and the antiapoptotic gene (Bclxl) were examined. Results: The expression of C3 increased to its maximum between 2448 h. The TUNELpositive cells and Bax protein expression increased gradually and reached the peak level between 4872 h. The Bclxl protein reached the peak level at 48 h. The correlation analysis showed that the quantity of C3 was positively related to that of the TUNELpositive cells, but the bax protein was not related to Bclxl protein. Conclusion: The expression of complement factor C3 may contributes to the nerve injury after cerebral hemorrhage and relate to the apotosis in the tissues surrounding the hametoma in rats.
