Objective To investigate the related risk factors for progress of the elderly frontal lobe contusions. Methods The clinical data of 118 cases of elderly frontal lobe contusions from August 2012 to August 2014 were retrospectivelyanalyzed.118 patients were given conventional therapy after admission,received dynamic review of brain CT.The progress of patients were performed surgery of frontal coronary approach,removed contusion brain tissue by bone flap of single frontal or double the frontal lobe.No progress of patients were given conventional conservative treat-ment.Selected seven indicators combining with hypertension,oral aspirin,diabetes mellitus,contrecoup injury,Cushing response,sylvian cistern exist or not and subdural hematoma did a statistical analysis.Results This group of 118 patients,68 cases (57.6%)had progress and 50 cases (42.4%)had no progress.Statistical analysis showed that oral aspirin (P =0.006 ),sylvian cistern exist or not (P =0.001 ),Cushing response (P =0.025 )were independent risk factors of progress of the elderly frontal lobe contusions.Conclusion For elderly patients with fron-tal lobe contusion,oral aspirin,sylvian cistern exist or not,whether there is any Cushing response were risk factors for deterioration of disease progression.If one or more risk factors appeared,clinical need to prevent disease progression.

Objective To explore MRI features of incontinentia pigmenti(IP) in central nervous system (CNS) in newborn infants.Methods MRI and clinical data of 17 cases of IP which confirmed by clinic,skin biopsy or NEMO gene test were analyzed retrospectively.Results There were 17 cases with IP in this study.MRI abnormalities were found in 12 cases, among which 3 cases showed high signal intensity on T2WI and a reduced signal intensity on T1WI,and 9 cases showed normal signal intensity on traditional MRI.Multiple areas of restricted diffusion were found in 12 cases which showed asymmetric high signal intensity in bilateral cerebral cortex and subcortical area, basal ganglia,centrum semiovale and periventricular area on DWI.In addition,basal ganglia was involved in 4 cases,corpus callosum was involved in 5 cases, and thalamus was involved in 2 cases.Conclusion MRI of IP in CNS shows certain specific characteristics.DWI plays an important role in the early detection and prognosis of the disease.

Objective To compare 18 F-FDG PET/CT and electronic endoscopy for measuring the length of esophageal squamous cell carcinoma (ESCC) and to evaluate the optimal SUV threshold for contour determination of the size of the lesion.Methods Twenty-four patients (19 males and 5 females,median age:59 years) with histologically confirmed ESCC were enrolled.Three patients had stage Ⅱ,14 had stage Ⅲ and 7 had stage Ⅳ diseases.PET studies were performed before treatment.The length of ESCC was measured on FDG PET imaging using different SUV thresholds of 2.0 (L2.0),2.5 (L2.5),3.0 (L3.0),3.5 (L3.5),and 35％(L35),40％(L40),45％(L45),50％(L50),55％(L55) of SUVmax.The length of ESCC on PET imaging was compared with the length of gross tumor in vivo measured by electronic endoscopy (Lst) to determine the optimal threshold of SUV using paired t test.Pearson correlation analysis was used to assess the correlation.Results The SUVmax of primary tumor was 14.51±5.72 and the Lst was (5.27± 2.45) cm.The length was in a descending order of L2.0,L2.5,Lst,L3.0,L3.5,L35,L40,L45,L50 and L55 when using different criteria.There were significant differences between the Lst and the lengths measured on PET except those by L2.5 and L3.0((5.65±2.69) cm,(5.11±2.51) cm; t=-1.74 and 0.76,both P＞0.05).The lengths measured on PET by all criteria were significandy correlated with the Lst,respectively,with the better r values by L3.5(0.935),L2.5(0.920) and L3.0(0.919) (all P＜0.01).When SUVm~＜15,there were no significant differences between the Lst ((4.82±2.14) cm) and L2.5((4.95±2.76) cm),L3.0((4.45±2.50) cm) and L35((4.42±1.85) cm),respectively (t=-0.439,1.299,2.011,all P＞0.05).The best correlation (r=0.953,P＜0.05) was between Lst and Lz5.When SUVmax ≥ 15,there was no significant difference between Lst ((5.67±2.64) cm) and L3.0((6.11±2.61) cm; t=-0.897,P＞0.05; r=0.791,P＜ 0.05).Conclusions For better correlation of ESCC lesion size,it is suggested that the optimal threshold of SUV for contouring is 2.5 for tumor SUVmax＜15,and 3.0 for tumor SUVmax ≥ 15.A larger sampling size is needed for further confirmation or modification.

Objective: To investigate the anticancer activity of Luteolin (Lu) and its synergism effect with bacillus calmette-guerin (BCG) on human bladder cancer cell line BIU-87. Methods: Cultured BIU-87 cells were treated with different concentrations of Lu alone or the combination of Lu with BCG. MTT assay was used to measure the cell proliferation inhibition, and IC50 was calculated. Cell cycle and apoptosis were analyzed by lfow cytometry with propidiumiodide (PI) staining and Annexin-V FITC/PI dual parameter markers to clarify the mechanism of inhibiting cell proliferation and inducing apoptosis. Caspase-3 and phosphorylated c-Jun N-terminal kinases (P-JNK) expression were measured to detect the apoptosis signal pathways of Lu in cancer cells. Results: Both Lu and BCG apparently inhibited the cell proliferation and induced the apoptosis dose-dependently, and microscope observation showed morphological changes in the apoptosis. Flow cytometry indicated that Lu arrested the cell cycle at G2 phase (P<0.05). It sensitized BCG-induced cytotoxicity and cell apoptosis, and upregulated expression of caspase-3 and activation of JNK (P<0.05). Conclusion: As an effective anticancer agent, Lu can sensitize the effect of BCG by inducing the cell cycle arrest and apoptosis. hTis synergism effect is achieved by activation of caspase-3 and JNK. Combination of Lu with BCG may be one of the potential treatment for bladder cancer.

Objective To investigate the treatment strategy of operation in torcular herophili meningiomas.Methods Retrospectively analyzed the treatment strategy of operation and follow-up data of 16 cases torcular herophili meningiomas patients.Results Grade Ⅰ resection was 9 cases,grade Ⅱ resection was 5 cases,grade Ⅳ resection was 2 cases.One patient appeared transverse thrombosis in postoperative.Followed up for 26-61 months,all patients had no recurrence.Conclusion By detailed preoperative evaluation,selection of appropriate operative approach,reasonable treatment of venous sinus adhesion tumor,supplemented by the necessary radiotherapy,can reduce the risk of operation and recurrence rate to torcular herophili meningiomas.

Objective To probe the relationship between the connectivity of premotor area detected by resting state functional MRI and stereotyped behavior of ASD.Methods 39 children patients with ASD and 42 healthy controls with matched age,sex and IQ were recruited.All the 81 subjects performed scaling with behavior scale index and underwent resting-state fMRI scans.After the fMRI data precession,the premotors in left and right sides were selected as ROI seeds to perform functional connectivity.Results Compared with healthy controls,children patients showed significant increased connectivity between the left premotor area and posterior cingulate cortex,as well as decreased functional connectivity between the left premotor area and the left insula.In addition, a negative linear correlation was showed between the connectivity of the left premotor and the insula and the behavioral scores.Con-clusion Imbalanced premotor functional connectivity may be one possible mechanism of stereotyped behavior of ASD,representing an attention deficit and/or impaired sensory perception to the external salient stimuli.

Objective To summarize the common complications of chronic lymphocytic leukemia (CLL). Methods 203 cases of CLL patients from the Institute of Hematology and Blood Diseases Hospital, CAMS & PUMC, were retrospectively reviewed and followed up.The common complications of CLL were also summarized. Survival analysis was used to analyze the prognostic value of these common complications. Results 40 (19.7 %) patients sustained infectious complications,and the respiratory tract infections were the most common type (75.6 %). 15 (7.4 %) patients complicated with autoimmune diseases (AID), and the autoimmune hemolytic anemia(AIHA) were the most common type(31.3%). 8(3.94 %) patients suffered from secondary cancers, including lung cancer, etc.3(1.48 %) patients developed other high-grade lymphomas, 2 of them transformed to prolymphocytic leukemia (PLL), 1 of them transformed to diffuse large B cell lymphoma (DLBCL) which was called Richter syndrome. Complicating infections and secondary cancers or transformations were associated with poor prognosis.Complicating AIDs was not an adverse prognostic factor. Conclusion Infections, AIDs and secondary cancers or transformations are common complications of CLL patients.Lung is the most common infectious site, and AIHA is the most common AID type,none secondary cancer s incidence rate is specifically higher than the others. Infections and secondary cancers or transformations indicate poor prognosis.

Objective To investigate the correct diagnosis and treatment of myeloid and lymophoid neoplasms with eosinophilia and the FIP1L1-PDGFR fusion gene. Methods A case of patient who was diagnosed as myeloid and lymophoid neoplasms with eosinophilia and the FIP1L1-PDGFR fusion gene was reported, and the literature was reviewed. Results The patient was diagnosed as typical T-lymphoblast lymphoma (T-LBL) by the lymph node pathologic diagnosis, while the diagnosis of myeloid and lymophoid neoplasms with eosinophilia and the FIP1L1-PDGFR fusion gene was made correctly by the whole examination and analysis. The patient acquired deep complete remission quickly after taking the low dose of imatinib. Conclusions Myeloid and lymophoid neoplasms with eosinophilia and the FIP1L1-PDGFR fusion gene are a rare hematologic tumor. Though pathological diagnosis is the golden standard for lymphoma, sometimes the other factors should be taken into consideration and make an overall analysis of clinical picture and a correct view of the pathological diagnosis, which could avoid the misdiagnosis and improper treatment.
