Objective To study the correlation between normal level of thyroid hormone and gensini coronary scor-ing system. Methods Coronary heart disease patient who were treated with Cardio-angiography (CAG) (n=231) were divid-ed into 4 groups based on gensini coronary score. All the patients were examined with indexes include total triiodothyronine (TT3), total thyronine(TT4), free thyronine(FT4), free triiodothyronine (FT3), thyroid stimulating hormone (TSH). And correla-tion between thyroid hormone level and gensini coronary scoring system was studied by Spearman correlation analysis and Multiple regression analysis. Results No significant difference was found in the levels of TT3, TT4, FT4, Cholesterol(CHO) and Triglyceride(TG) between the all 4 groups (P>0.05). FT3 and HDL-C decreased with the increase of extent of coronary artery lesions(P<0.01), and AGE and LDL-C raised with the coronary artery lesions extent (P<0.05). Gensini coronary scoring system was linearly negatively correlated with FT3, HDL-C and positively correlated with age and LDL-C. Age, FT3,HDL-C,LDL-C was independently correlated to Gensini score. Conclusion The lower level of FT3 is an indepen-dent risk factor for CHD.

Diffuse large B cell lymphoma (DLBCL) is one of the most common non-Hodgkin lymphoma (NHL).Since the appearance of rituximab,the most common first-line therapy is rituximab in combination with chemotherapy.About 70 percent of patients could achieve complete remission (CR) and be cured finally.But one third of patients could not reach CR after frontline treatment or relapse early,especially the elder patients or high risk ones.In the 56th American Society of Hematology (ASH) annual meeting,a plenty of treatments focusing on these patients brought encouraging results,which makes it possible to further improve the CR rate.The progresses in relapse/refractory,high risk and special site DLBCL will be summarized in this paper based on the reports in the 56th ASH annual meeting.

Objective To investigate the influence of different interventional treatment timing on the prognosis of patients with intracranial aneurysms. Methods One hundred and thirty-eight patients with ruptured intracranial aneurysms were divided into group A (Ⅰ- Ⅲ grade) with 109 cases and group B ( Ⅳ- Ⅴ grade) with 29 cases according to Hunt-Hess grade when admitted. All patients received interventional treatment, the operation period was divided into early, middle and late stage according to the different time from disease time to operation, then compared the good rate, cerebral vasospasm and hydrocephalus incidence of patients underwent surgery at different period. Results The good rate at different period in group A were respectively 69.7% (23/33),58.8% (10/17) and 61.0% (36/59),which and the cerebral vasospasm and hydrocephalus incidence of patients underwent surgery at different period in group A had no significant difference(P > 0.05). The good rate of patients received surgical treatment at early stage in group B was 46.2%(6/13), which was significantly superior to late stage (0), the difference was statistically significant (P < 0.05), while the cerebral vasospasm and hydrocephalus incidence of patients underwent surgery at different period in group B had no significant difference(P> 0.05). Conclusion The prognosis of patients with Hunt-Hess grade Ⅰ - Ⅲ grade undergoing interventional treatment at early, middle and late stage can be satisfactory, while grade Ⅳ - Ⅴ grade patients should receive interventional treatment at early stage.

Peripheral T-cell lymphoma (PTCL) is a group of highly heterogeneous and aggressive non-Hodgkin's lymphoma with poor prognosis under current treatment algorithm.Reports on treatment of PTCL in the 56th American Society of Hematology (ASH) annual meeting cover comprehensive aspects,among which exploration of effective low-toxicity treatment strategies for patients with PTCL is coming into the focus of this meeting.THP-COP regimen,romidepsin,bortezomib alone or in combination with panobinostat,brentuximab vedotin and stem cell transplantation provide more attractive options for both untreated and refractory/relapsed patients with PTCL,while novel drugs including Duvelisib (IPI-145),crizotinib and antiPD-1 antibody offer new hope for patients with PTCL.

Objective To explore the correlation between the enhancement pattern of hepatocellular carcinoma (HCC) on contrast-enhanced ultrasound (CEUS) and its tumor differentiation on histopathology. Methods HCC lesions (n=259) from 224 patients were retrospectively evaluated with CEUS and histopathological examination. CEUS was performed with SonoVue. The characteristics of blood perfusion and parameters of the time-intensity curve (TIC) were analyzed by ACQ soft?ware. Histopathological diagnoses were decided base on Edmonson grading system. Results Pathologic grading of HCC was not related to the arrival time(P>0.05);The washing-out time point and the enhancement time point and peak time point all appeared earlier in poorly differentiated HCC group, than those in moderately differentiated HCC group than those in well differentiated HCC group(P<0.01);The enhancement time point and the expurgation time point are shorter in poorly differ?entiated HCC group than those in moderately differentiated HCC group than those in well differentiated HCC group. All dif?ferences were with statistical significance. The mode of arterial perfusion in early stage was divided into 3 types:spider web type, radiative type and mixed type. The well differentiated HCC group mainly presented as radiative type ( 28/49, 47.14%). But the most of poorly differentiated HCC group mainly present as spider web type(88/127, 69.29%). The mix type was more common in moderately differentiated HCC group(49/83, 59.03%). Conclusion CEUS show different features of TIC pa?rameters and blood perfusion in different pathological stages of HCC lesions so it can serve as a method to assess the biologi?cal behavior of hepatocellular carcinoma.

Phospholipids and their metabolites play an important role in a variety of cellular processes including cell-cell adhesion, cell growth and differentiation, apoptosis, phagocytosis as well as storage of energy. In this study, the phospholipid composition of cancer tissue and adjacent normal tissue from humans and animals were analyzed by internal extractive electrospray ionization mass spectrometry ( iEESI-MS ) . Extractive solvent at high voltage (+5. 5 kV) was injected into tissue samples using a fused silica capillary at a flow rate of 0. 5-1 μL/min, producing fine charged droplets containing analytes of tissue samples at the tip of the sample. Charged droplets were directly sampled to the atmospheric inlet of a mass spectrometer. Out of 21 different ratios of CH3 OH ∶H2 O solvent mixture, the ratio CH3 OH ∶ H2 O=30∶70 ( V/V ) showed the optimal phospholipids extraction and visibility in MS. A large number of phospholipids from different tissue samples ( such as cancer tissue and adjacent normal tissue of lung cancer, esophageal cancer tissue, pork, beef, porcine heart and porcine lung) were obtained simultaneously by iEESI-MS analysis. The experimental results demonstrated that iEESI-MS was characterized by minimal sample pretreatment, low sample consumption, and rapid analysis ( the analysis time per sample was less than 1 min) , and the selectivity and sensitivity of iEESI-MS could be improved by choosing proper solvent. Importantly, the experimental results provided new information for further studies of phospholipids in biological tissues.

Objective To explore the risk factors of hyponatremia in postoperative patients with aneurysm and analyze the clinical characterstics in order to provide reference for clinic.Methods Participants included 120 patients who treated by aneurysm occlusion.Detailed recorded the patient's history and basic information.The patients with hyponatremia were in case group,and other patients were in control group.The risk factors of hyponatremia were analyzed.Results Forty-five patients (37.5％) occurred hyponatremia after operation.The level of natrium was (125.2 ± 10.1) mmol/L,the average time of appear hyponatremia was (8.2 ± 0.8) d,15 patients were in the first peak(postoperative 1-3 d),25 patients were in the second peak (postoperative 8-9 d),5 patients occurred hyponatremia at other time.Thirty-nine patients were internal carotid artery aneurysms,6 patients were vertebrobasilar artery aneurysms.Single factor analysis showed that the age,preoperative GCS scores,history of hypertension and diabetes,emergency operation,the size of arterial aneurysms,medium-sized aneurysm of artery between two groups had significant difference [(48.7 ± 8.4) years vs.(54.7 ± 8.4) years,(14.4 ± 3.1) scores vs.(10.3 ± 3.4)scores,26.7％ (20/75) vs.60.0％ (27/45),33.3％ (25/75) vs.62.2％ (28/45),32.0％ (24/75) vs.62.2％(28/45),(0.9 ±0.3) cm vs.(1.4 ±0.4) cm,24.0％(18/75) vs.42.2％(19/45),P ＜ 0.01 or ＜ 0.05].Multifactors regression analysis showed that preoperative GCS scores,emergency operation were the independent risk factors of hyponatremia (P＜ 0.05).Conclusions Postoperative 1-3 d and 8-9 d are the peak stage of hyponatremia.Different treatment should be adopted according the peak stage.Lower scores of preoperative GCS and emergency operation are the independent risk factors of hyponatremia.Clinical work need to pay more attention to the risk factors,appropriate treatment and prevention.

ObjectiveTo investigate the role of electroencephalogram (EEG) examination in the prognosis evaluation of patients with severe craniocerebral injury.MethodsFifty-seven patients with severe craniocerebral injury were selected as study subjects and their clinical data were analyzed retrospectively.All the patients got EEG examination,and the relationships between EEG grading and Glasgow coma scale (GCS) score,the prognosis of outcome were analyzed.ResultsThe EEG of 57 patients within 24 h after hospitalization were all abnormal.There was significantly negative correlation between EEG grading and GCS score (r =-0.742,P ＜0.05).EEG grading was significantly positively correlated with the prognosis of outcome (r =0.730,P＜ 0.05).ConclusionsEEG examination and EEG grading can evaluate the prognosis of patients with severe craniocerebral injury.It provides reference for clinical treatments.

Diffuse large B-cell lymphoma (DLBCL) is one of the most common non-Hodgkin lymphomaaccounting for 30 %-40 %. The most common first-line therapy for DLBCL is rituximab in combination withchemotherapy. About two thirds of patients treated by the first-line therapy achieve a complete remission (CR)and are cured finally, but nearly one third of patients can not reach CR after frontline treatment appearingrefractory or relapse early, especially for the high risk patients or cases with MYC alterations, the regimenimproving the long-term survival is not much. In the 57th American Society of Hematology (ASH) annualmeeting, a plenty of treatment as focus on these patients brought in encouraging results, which makes itpossible to further improve the CR rate. The progresses on DLBCL of relapse and refractory, high risk andspecial types were summarized in this paper based on the reports in the 57th ASH annual meeting.
