Updated knowledge about lymphoma pathology has been accumulated ever since the publication of the current WHO classiifcation of lymphomas in 2008. For B-cell non-Hodgkin lymphomas, endeavors have been made for approaching a better classiifcation of those highly aggressive and heterogeneous subtypes (e.g., diffuse large B-cell lymphomas) on the molecular biological basis. In addition, there is a growing interest in understanding and deal-ing with the borders of overt malignant lymphomas and certain clonal lymphproliferative disorders that are not overtly malignant. On the other hand, recent advances in understanding the subsets of T and NK (T/NK)-cell lineage and their differentiation, as well as the genetic aberrations or dysregulated signaling pathways in their neoplastic counterparts, have provided us novel insights into the biology of peripheral T/NK-cell lymphomas. Indolent clonal T/NK-cell prolif-erations, especially those arising from the mucocutaneous sites, have also received increased attention. These advances may contribute to the evolution of the classiifcation of lymphomas.

Due to the high incidence and mortality of digestive system malignant tumor,so it is of great significance to make further research for digestive tract tumor.Platinum drugs,one of the traditional drugs which is used for the chemotherapy for digestive system tumor,which has been extensively applied to the chemotherapy for malignant tumor.However,the resistance to the drugs exerts a serious influence on its curative effect.At present,it is believed that the nucleotide excision repair(NER)constitutes one of the most important mechanisms which results in the resistance to platinum drugs,mainly because it causes the twisting of DNA helix by removing large numbers of platinum compounds.The nucleotide excision repair cross complementation group 1(ERCC1)plays an important role in the process of NER.The different expression of ERCC1 in peripheral blood and tumor tissue of patients with digestive sysem tumor has a close connection with therapeutic effect of the platinum-containing chemotherapy.This article aims to provide an overview of the relation between the ERCC1 research development and the curative effect of cisplatin chemotherapy for digestive system tumor.

Diffuse large B-cell lymphoma (DLBCL) is a heterogeneous disease in terms of molecular pathogenesis and cell of origin. Earlier prognostic models relied mainly on such clinical variables as age, stage of disease, and performance status, which did not display its heterogeneity. Many studies have reported that some biomarkers could be used for prognostication, while older prognostic models need to be revalidated and modified as improved therapeutic options become available. In this review, we discussed pertinent studies on individual biomarkers and pattern-based biomarker models, with an emphasis on markers evaluated in patients treated with rituximab-containing chemotherapy.

Objective To evaluate the levels of serum organochlorine pesticide residues in breast cancer patients and benign breast disease patients from Tangshan areas. Methods One hundred fifty-eight breast cancer patients and 129 benign breast disease patients from two districts of TangShan were entrolled in the study. The levels of serum organochlorine pesticides ( DDTs and HCHs) were detected through gas chromatography/electron capture. Spearman's rank correlation was used between age, BMI and the level of serum organochlorine pesticide residues in patients. Results The serum levels of a-HCH, p-HCH and PP'-DDE between breast cancer patients and benign breast disease patients were statistically different(P <0. 05). The serum levels of p-HCH and PP'-DDE were positively correlated with age and BMI in both groups, with correlation coefficients of 0. 272 and 0. 330 for age and 0. 207 and 0. 313 for BMI in the breast cancer patients,as well as correltion coefficients of 0. 339 and 0. 260 for age and 0. 227 and 0. 209 for BMI in the benign breast disease patients. Conclusions The levels of organochlorine pesticide residues in serum in breast cancer patients were higher than those in benign breast disease patients and were positively correlated with age and BMI. The results offer more information to the pathogenesis, prevention and control measures of breast cancer.

Objective To observe the efficacy of Buyanghuanwu herbal decoctions on microalbuminur in noninsulin-dependent diabetes mellitus. Methods Sixty-six patients with noninsulin-dependent diabetes mellitus patients with 30～300 mg/24 h microalbuminur were randomly divided into the treated group (treated with Buyanghuanwu herbal decoctions) and the control group (treated with injection of Huangqi). The clinical efficacy was observed and levels of blood-fat, hemorheology and microalbuminur were determined. Results The levels of blood-fat, hemorbeology and microalbnminur were decreased in treated group. Comparison between the two groups showed significant difference (P

Objective To discuss the clinical and pathological features of herniation secondary to cerebral infarction. Method Clinical and pathologic characteristics of 50 cases died of herniation due to cerebral infarction were analysised. Results The clinical manifestations,such as consciousness disturbance,pupillary change,hemiplegia or tetraplegia were detected in all 50 cases,the average time from onset to herniation was (3.36?1.12)d,the time herniation to death was 20 h～7 d,average about (1.5?0.98)d. The large size cerebral infarctions caused by internal carotid artery,middle cerebral artery and/or vertebral artery occlusion were pathologically confirmed.hemorrhagic cerebral infarctions caused by cerebral embolism were found in 25 cases and the ischenmic infarctions caused by cerebral thrombosis in 25 caese.Site of infarction were cerebral hemisphere (31 cases), brain stem (15 cases), supratentorial and infratentorial brain (4 cases).Of the 50 cases,36 cases had hippocampal gyrus herniation,36 cases with cerebellur throat-almond herniation,18 cases with central herniation,17 cases with cingulated gyrus herniation,and 27 cases with sphenoidal crest herniation. Usually there were several herniation existing in the same patient. Among 50 cases,11cases had two kinds of herniation,10 cases with three kinds of herniation,9 cases with four kind of herniation, and 5 cases with five kinds of herniation.Conclusions Herniation secondary to cerebral infarction were mainly presented in the large size cerebral infarction caused by internal carotid artery or middle cerebral artery occlusion.the time of herniation was in early stage of disease.Most of patients were hippocampal gyrus herniation and cerebellur throat-almond herniation.Usually there were several herniation existing in the same patient.

Objective To discuss the clinical characteristics and pathological changes of basilar artery aneurysm.Methods The clinical materials and brain topography results were analyzed retrospectively in 4 patients with basilar artery aneurysm.Results The onsets of disease in all cases were acute and common manifestations were coma,positive meningeal irritation sign and ocular dyskinesis.3 cases showed hypertention,2 cases presented with hemiparalysis,all cases died of herniation.3 cases of basilar artery trunk fusiform aneurysm and 1 case of basilar artery furcation saccular aneurysm were detected in autopsy.There were aneurysm rupture,subarachnoid hemorrhage and swell,necrosis,softening,gliosis of brain tissue confirmed pathologically in all cases.Conclusion Hypertension is probably the most important cause of aneurysm rupture.Signs and symptoms of subarachnoid are the most common manifestation when basilar artery aneurysm ruptures with poor prognosis.Herniation is the main cause of death.

Objective To study the clinical feature of 26 cases which were diagnosed pathologically as cerebral amyloid angiopathy ( CAA ) and to improve the level of diagnosis.Methods The clinical characteristics of the 26 cases with CAA in our hospital from 1983 to 1999 were retrospectively reviewed and analyzed,including previous history,clinical manifestation,and laboratory examination.Results Of the 26 CAA patients,there were 17 men and 9 women with age ranging from 45 to 78 years.Eight patients (30.7％ ) had the history of hypertension; 6 cases (23.1％ ) suffered from diabetes; 2 patients(7.6％ ) were taking anticoagulant or antiplatelet agents in whom serious CAA and multiple hemorrhages were histopathologically confirmed by autopsy.There were 20 cases diagnosed as cerebral hemorrhage,including 2 patients with single lobe hemorrhage,8 patients with multiple lobe hemorrhage,5 patients with putamen hemorrhage,2 patients with cerebral ganglion hemorrhage,2 patients with cerebellar hemorrhage,and 1 patient with brain stem hemorrhage.Of the 26 CAA patients,there were 2 patients with subaracchnoid hemorrhage,1 patient with hemorrhagic cerebral infarction,1 patient with basal ganglia infarction,1 patient with basilar artery occlusion,1 patient with subdural hematoma.The clinical manifestation of the 20 cases diagnosed as cerebral hemorrhage included headache,limb palsy,coma,and hyperspasmia.Conclusions CAA always begin as cerebrovascular disease symptoms with or without hypertension.The most common manifestation of CAA is lobe hemorrhage,while the CAA-related hemorrhage seldom occurs in basal ganglia,cerebellum and brainstem.CAA can also manifest cerebral infarction and subarachnoid hemorrhage.Anticoagulant (warfarin) or antiplatelet agents (aspirin) maybe a contributing factor for CAA-related hemorrhage.
