Objective　To try to improve early diagnosis of primary gastric malignant lymphoma. Methods　Analyse the clinical manifestations. radiologic and endoscopic findings in 10 cases. Results　2 patients were diangosed by means of endoscopic biopsies while the other 8 ases were proved by operation, among them 2 patients died one year after operation.Conclusion　No specific clinicil manifestations were found. Large biopsy specimens and multiple biopsy specimens of any suspicious area are essential for early diagnosis. The radiographic and endoscopic finding are described and immunohistological examinations are helpful. CHOP regieme is the choice of chemotherapy. Erradiation of H. pylori is important. The prognosis is related to the clinical staging.

Objective To investigate the cause and treatment for ischemic ophthalmopathy after cataract phacoemulsification.Methods A total of 3000 patients with cataract underwent phacoemulsification were retrospectively analyzed,and 13 patients with ischemic ophthalmopathy.The ischemic optic neuropathy (ION) were in 8 cases,7 cases occurred in age related cataract,1 cases occurred in the dislocation of lens;The central retinal artery occlusion (CRAO) were occurred in 5 cases,1 cases of age-related cataract,2 cases of congenital cataract,2 cases of traumatic cataract.The patients were diagnosed with fundus,visual field and fundus fluorescein angiography respectively,and then were treated with dilation of blood vessels,nutrition nerves and symptomatic treatment.Results The visual acuity in 6 cases with ION after the treatment were improved in different degrees;The visual acuity in 2 cases with CRAO after treatment were improved,3 cases was not recovered.Conclusion Ischemic ophthalmopathy caused by phacoemulsification cataract surgery may be related to the main vascular disease or optic nerve ischemia and hypoxia during operation,and with early detection and treatment,visual acuity can be improved to some extent.
