Objective To analyze clinical and radiological characteristics of intracranial hemorrhage in hematological diseases to improve the recognition of them. Methods Thirty-one clinical data of intracranial hemorrhage cases with hematological diseases were reviewed. The basic diseases, clinical and radiological manifestations, and risk factors of mortality were analyzed. Results Intracranial hemorrhage usually occurred in patients with acute myeloid leukemia (AML) or idiopathic thrombocytopenic purpura (ITP),and 13 and 6 cases, respectively, in this group. Most patients presented with headache, restlessness, nausea,vomiting, conscious disturbance and no localization sign by physical examination. CT or MRI images often revealed focus of errlysis. Compared with CT scan, a higher detection rate of ICH could be realized by MRI scan. The total mortality in this group of ICH patients was 71% (22/31). Fever, white blood cell >5×109/L,platelet <50×109/L, hyperimmunoglobulinemia and disturbance of blood coagulation were risk factors for ICH of this group of patients. The mortality was higher in patients with no less than 2 risk factors[86.4 % (19/22)vs 33.3 % (3/9)] (x2 = 8.718, P = 0.003). Conclusion ICH is a serious complication for hematological patients. MRI scan is good at improving the diagnosis of ICH. It is of high risk of death in patients with no less than 2 risk factors such as fever, white blood cell higher than 5×109/L, platelet less than 50×109/L,hyperimmunoglobulinemia and disturbance of blood coagulation.

Objective To report our experiences in the treatment of recurrent intracranial aneurysms with re-coiling or covered stents.Methods A total of 291 patients with 305 intracranial aneurysms were treated with detachable coils.and 41(28.9%)of 142 patients with aneurysms in the intemal carotid artery had a recurrent aneurysm during the follow-up period.For this study,31 recurrent aneurysms in 31 patients who had angiograms within 6 months following retreatment with detachable coils(group A,n=20)or covered stents(group B.n=11)were analysed.Aneurysms were categorised as complete or incomplete occlusion via angiographic assessment and graded as full recovery,improvement,no change or deterioration via clinical assessment.Data regarding technical success,initial and final angiographic results,final clinical outcome were collected and analysed postoperatively.Results Coil embolisation and covered stent placement.were technically successful in all recurrent aneurysms.The initial angiographic results showed complete occlusion in 11 patients(55%)in group A and in eight(72.7%)in group B(P=0.452),and the final angiographic results exhibited complete occlusion in 10 patients(50%)in group A and in 11(100%)in group B(P=0.005).There were no significant differences in technique success or final clinical outcome between the two groups.Conclusions Recurrent aneurysms after coiling can be successfully treated and occluded with re-coiling or covered stent placement.However,covered stents seem to be more effective than re-coiling with regard to complete occlusion of recurrent aneurysms.

Objective To investigate the application value of mini-nutritional assessment short-form(MNA-SF) in screening and evaluating nutritional status in elderly hospitalized patients with malignant tumor.Methods 1472 elderly hospitalized patients(≥65 years old)with malignant tumor were enrolled and prospectively studied for evaluating the nutritional status by nutritional risk screening 2002 (NRS 2002)assessment.Indicators of clinical outcomes were summarized.The consistencies of MNA-SF with body mass index(BMI),grip and results of NRS 2002 assessment,and the relationship between the different nutritional status and clinical outcomes were analyzed.Results The patients meeting the inclusion/exclusion criteria were aged(72.1±5.9)years,with BMI of(22.3 ±3.7)kg/m2 and grip of(21.7± 19.0)kg.Among 16.7% of the malnourished patients with malignant tumors,pancreatic cancer (30.9 %),bile duct cancer (24.1%) and esophageal cancer (21.2 %) occupied the top three incidence of malnutrition,with the lowest (5.4%)incidence in breast cancer.Among 59.2% of patients being malnourished (16.7%)or at risk(42.5%)of malnutrition,the highest incidence was in bile duct cancer(82.8%),and lowest one was in breast cancer(28.6 %).MNA-SF-discriminated malnutrition(0~ 7 points)showed a great agreement with malnutrition evaluation by BMI(<18.5),but had a poor agreement with grip in screening malnutrition.MNA-SF-discriminated nutrition problem(malnourishment plus at risk of malnutrition)showed a great agreement with NRS 2002-discovered nutrition problem (score≥3).Under-nourished patients had a higher infection complication(9.29% vs.5.14%,P =0.006)and longer hospital stays(15.4 d vs.12.8 d,P<0.01)as compared with patients with normal nutrition status.Conclusions The prevalence and risk factors for malnutrition are higher in elderly patients with malignant tumor.Poor nutritional status is correlated with poor clinical outcomes.MNA-SF can be used as a tool for evaluating the nutritional status of elderly patients with malignant tumor.

Beijing has been one of the epicenters attacked most severely by the SARS-CoV (severe acute respiratory syndrome-associated coronavirus) since the first patient was diagnosed in one of the city's hospitals. We now report complete genome sequences of the BJ Group, including four isolates (Isolates BJ01, BJ02, BJ03, and BJ04) of the SARS-CoV. It is remarkable that all members of the BJ Group share a common haplotype, consisting of seven loci that differentiate the group from other isolates published to date. Among 42 substitutions uniquely identified from the BJ group, 32 are non-synonymous changes at the amino acid level. Rooted phylogenetic trees, proposed on the basis of haplotypes and other sequence variations of SARS-CoV isolates from Canada, USA, Singapore, and China, gave rise to different paradigms but positioned the BJ Group, together with the newly discovered GD01 (GD-Ins29) in the same clade, followed by the H-U Group (from Hong Kong to USA) and the H-T Group (from Hong Kong to Toronto), leaving the SP Group (Singapore) more distant. This result appears to suggest a possible transmission path from Guangdong to Beijing/Hong Kong, then to other countries and regions.
