The intra-arterial thrombolysis is one of the most effective approaches in salvaging brain ischemic penumbra and treating acute cerebral infarction.However,because of the limita- tions of short time windows for treatment,intracerebral hemorrhage after thrombolysis and reocclusion,more clinical studies are needed before this technique is widely developed and applied.

Public Health Ophthalmology is a population-,region-or country-based as a whole object,and is committed to improving the eye health of the whole population.Epidemiological investigation of the eye was named to the region from a single disease to variation of diseases from cross-sectional survey to a longitudinal cohort study.Epidemiological investigations is the most important way which can reflect the pathogenic factors for public health policy-making,early diagnosis and prevention and treatment of eye disease,and Research to Prevent Blindness.Imaging Diagnosis,quality control,improve the reliability of the epidemiological investigation,and to strengthen the study of disease,race,and molecular levels and create a unique epidemiological study.

Objective To evaluate the diagnostic value of endoscopic ultrasonography-guided fineneedle aspiration(EUS-FNA)for pancreatic occupying lesion,especially pancreatic cancer.Methods From year of 2005,37 patients with suspected pancreatic cancer by means of uhrasound,CT or MRI received EUS-FNA.Amylase and tumor markers(CEA,CA19-9 and CA125)in cyst fluid were analyzed if applicable.The patients were followed up till July 2008,and the results of EUS-FNA were compared with those confirmed during the follow-up.Results The EUS-FNA yielded diagnosis of 16 cases of pancreatic duetal adenocarcinoma,1 metastatic:renal cancer,5 suspicious malignancy,6 atypia,6 normal pancreatic tissue,and 3 normal non-pancreatic tissue.During the follow-up,25 cases of pancreatic cancer and 10 benigh lesions,including 4 chronic panereatitis,4 cyst-adenoma and 2 pseudocyst,were confirmed,and the other 2 cases still remained un-determined.The sensitivity,specificity,positive predictive value and negative predictive value of EUS-FNA were 80.0%(95% CI:59.0-93.0),100.0%(95% CI:60.0-100.0),100.0%(95% CI:80.0-100.0),and 55.6%(95% CI:27.0-79.0),respectively.No severe procedurerelated complication was observed.Conclusion EUS-FNA is a safe and effective medality for diagnosis of pancreatic occupying lesions,especially pancreatic cancer.

Objective To explore the pathogenesis of thrombocytopenia in chronic type B hepatitis. Methods The serum thrombopoietin (TPO) levels, bone marrow megakaryocyte (MK) count, platelet-associated immunoglobulin G (PAIgG), splenic index (SPI), prothrombin activity (PTA) were measured in 76 chronic type B hepatitis patients with thrombocytopenia. Results The regression analysis revealed that the platelet count was correlated with parameters including the serum TPO levels, bone MK count, SPI and PTA (r was 0.450, 0.521, -0.438, 0.428 respectively, P<0.05). The regression equation was Pt=36.38+0.23 TPO-0.57 SPI+0.69 MK, R<'2>=0.57, F=18.78, P<0.01. Conclusion It suggests that decline of thrombopoiedn, myelosuppression and hypersplenism may contribute to thrombocytopenia in chronic type B hepatitis patients.

Objective To analyze the recuperation of lungs after TECAB, and probe more effective nursing care for the lungs of patients after TECAB. Methods 20 cases received the treatment of TECAB were collected during the period of January 2009 to July 2010. Due to the reason of ventilation with single lung, patients were demanded to strength breath and take right lateral position and treated with back-tapping in left lung. Meanwhile, patients were treated with back-tapping with lower intensity and more times and lower frequency vibration ( 10 - 15 time/s). The recuperation of patients were observed and analyzed. Results After treatment, the value of PaO2 and PaCO2 were in normal range, and no complications were occurred and all of them recovered from illness. Conclusions Effective and well-targeted lungs nursing is an important assurance that helps the sufferer to recover from illness and the new lungs nursing after one-lung ventilation in TECAB is effective.

Objective To define the heterogeneous changes of ion channels in the noninfarcted myocardium after myocardial infarction in rabbit and effects of imidapril.Mehods Rabbits with left coronary artery ligation were prepared and allowed to recover for 8 wk.Myocytes were isolated from subendocardial,midmyocardial and subepicardial regions of the noninfarcted left ventricular free wall.Ion currents were recorded with whole-cell patch clamp way.Results The densities of the transient outward K+ currents (I to) and the inward rectifier K+ currents (I K1) were greatly reduced in midmyocardium and subepicardium while two currents reduced gently in subendocardium.The densities of the delayed rectifier K+ currents (I K) were reduced in noninfarcted three layers similarly.Imidapril could reverse the changes of membrane currents in healed myocardial infarction cells and depress the dispersion of repolarization.Conclusions The heterogeneities of K currents are enhanced in noninfarcted area.Normalization of heterogeneous changes of repolarization after treatment with imidapril was observed.

Objective To better characterize the clinical and histopathological manifestations, diagnosis and differential diagnosis of epithelioid sarcoma (ES).Methods Clinical data were collected from nine patients with ES diagnosed and treated at the Institute of Dermatology, Chinese Academy of Medical Sciences and Peking Union Medical College from 2000 to 2014.The clinical and histopathological manifestations, immunophenotype, treatment and prognosis of ES were reviewed retrospectively.Results The median age at onset of ES was 34.5 years in these patients, and the average disease duration was 8.3 years.Lesions began on the extremities in 8 patients, and manifested as nodules,ulceration and lymphedema.Histopathological examination showed that tumor cells mainly consisted of spindle cells and epithelioid cells, some of which were in a palisade arrangement with central necrosis.Cytokeratin, epithelial membrane antigen (EMA) and vimentin were coexpressed by tumor cells.Recurrence was observed at the original site in 6 patients after lesion resection, and pulmonary metastasis occurred in 4 patients.Five patients were followed up and two of them died of pulmonary metastasis.Conclusions Local recurrence is frequent in patients with ES after lesion removal.Lymph node and pulmonary metastases of ES are common, and pulmonary metastasis is usually associated with a poor prognosis.
