Objective To study the efficacy and toxicity of standard CEOP regimen in elderly patients with non-Hodgkin's lymphoma (NHL).Methods The study included 34 previously untreated patients,age 60 to 80 years old,with NHL,through July 2009 to December 2011.The patients with T-cell lyphoma received four to eight cycles of CEOP (cyclophosphamide 750 mg/m2 d1,epirubicin hydrochloride 60-75 mg/m2 d1,vincristine 2mg d1,and dexamethasone 10-15 mg d1-5) every 3-4 weeks.Otherwise,the patient with B-cell lymphoma received R-CEOP,rituximab (375 mg/m2) was administered one day before CEOP.All the patients' clinical materials were collected and used to annalyze the efficacy and toxicity of the CEOP±R regimen.Results Among these 34 NHL patients,17 cases reached CR,9 cases reached PR,3 cases remained SD,and 5 cases appeared PD.The total response rate was 76.5 ％(26/34).The major toxicity was bone marrow restraint.The rate of leukocyte decline with Ⅲ-Ⅳ degree was 71.4 ％ (24/34).Conclusion Using the standard regimen of CEOP leads to satisfied efficacy of elderly patients with NHL,and the toxcity is tolerant.

ObjectiveTo investigate the clinical and MRI features of multiple sclerosis in children,including the clinically isolated syndrome (CIS) and relapse.MethodsIn total,16 cases of pediatric multiple sclerosis were included in this study.Of them,11 patients were female and 5 were male,with the mean onset age of 10.1 years.They were followed up for 4 months to 7 years and found to have 1-5 relapses.The clinical manifestations of CIS and relapse were analyzed by a pediatric neurologist.An experienced neuroradiologist reviewed the MRI images of CIS and relapse.Information on the location,size,and pattern of the lesions was gathered.The location of lesions included subcortical,central,and periventricular white matter,cortex,deep gray matter,brain stem,and cerebellum.ResultsCIS episode presented acute onsets in 13/16 cases,with symptoms of cortice in 10 cases and visual impairment in 6 cases.Relapse occurred in 14/16 cases within one year.The incidence of symptoms of cortice was less frequent and severe in the second episode of MS,whereas the visual impairment had a high incidence.All patients had full recovery after the last episode.MRI of CIS showed confluent subcortical white matter lesions in 13/16 cases,abutting on central white matter lesions.The most frequently involved brain part was the frontal lobe,followed by the parietal lobe.Cortical involvement was observed in 9/16 cases.In 6 cases,periventricular white matter lesions were detected.Bilateral deep gray matter was abnormal in 4 cases.Other abnormalities included brain stem lesions in 5 cases,cerebellum lesions in 3 cases,optic nerve involvement in 3 cases,and pyramidal tract lesions in 2 cases.MRI of relapse revealed more small lesions in the subcortial and periventricular white matter in the patients.In the second episode,only 2 cases presented cortical involvement.Lesions were found in the brain stem in 4 cases and in the cerebellum in 5 cases.Pyramidal tract involvement was identified in 6 cases,serving as “railway track sign”.ConclusionsCIS in children is characterized by large confluent lesions in subcortical white matter coalescing with central white matter.MRI of relapse showed distinctive “railway track sign”.It is important to integrate MRI and clinical features in the diagnosis of pediatric multiple sclerosis.

DMD/BMD is a X-linked recessive hereditary disease.It predominantly affects males.While female carriers do not have symptoms,due to their inactive X chromosome make it present mosaic.Recently,more and more papers reported that a clinically significant proportion of DMD/BMD female carriers have symptoms.They presented variable degrees of symptoms.But the mechanism of the pathogencity is still not clear.Most of the research considered that the dominating reason is the skewed X inactivation.It means that the predominant expression of the DMD mutant allele make the normal one have weak expression,thus no function dystrophin proteins could be generate,manifested as DMD/BMD.In this paper,we mainly summarized the relationship between skewed X inactivation and pathogenicity of the symptomatic DMD female carriers.

Objective To investigate the effects of long-term low-dose radiation (LDR) of γ-rays on the proliferation and radiosensitivity of human lymphoblast cells HMy2.CIR (HMy) and to elucidate the underlying mechanism.Methods HMy cells were divided into control group and long-term LDR group.For the long-term LDR treatment,HMy cells were fractionally exposed to a low dose of γ-rays,which could enhance cell proliferation,3 times per week for 4 weeks.After the long-term LDR exposure,part of the control and long-term LDR exposed cells were further irradiated with a challenging dose (2 Gy) of γ-rays.Then cell proliferation and radiosensitivity were assayed by CCK-8 kit,cell apoptosis,and γ-H2AX formation was measured by flow cytometry.Gene expressions of cyclinD1,PCNA,bcl-2 and bax were detected by RT-PCR.Results The long-term LDR significantly increased cell proliferation (t =9.607,P ＜ 0.01) accompanied with up-regulation of cell cycle regulation gene cyclinD1 (t =6.869,P ＜ 0.01),proliferation regulation gene PCNA (proliferating cell nuclear antigen) (t =9.229,P ＜ 0.01) and bcl-2 gene (t =2.662,P ＜ 0.05),but decreased the expression of pro-apoptotic gene bax (t =19.908,P ＜0.01) in HMy cells.Compared to untreated cells,the long-term LDR decreased cell radiosensitivity (t =8.896,P ＜ 0.01),including apoptosis induction (t =4.762,P ＜ 0.01) and γ-H2AX formation (t =10.264,P＜0.01).Conclusions The long-term LDR promoted cell proliferation by up-regulating cell cycle related genes,while it reduced the radiosensitivity of HMy cells with acquisition of apoptotic resistance.

Objective To analyze the change of surgical route and range of hysterectomy in the past 10 years.Methods From January 2000 to December 2010,the clinical data of patients with hysterectomy were analyzed retrospectively,including clinical features,surgical path and scope of operation.Results There were 1980 patients.The predominant reason for hysterectomy was leiomyomas (52.88％,1047/1980),adenomyosis (17.78％,352/1980),cervical intraepithelial neoplasia (12.17％,241/1980).The age of the patients with hysterectomy for abdominal,transvaginal and laparoscopic was (46.54 ± 7.35),(58.73 ± 10.49),(44.10 ±5.12) years.In 2000-2005,the proportion of abdominal,transvaginal and laparoscopic proportion were 81.78％ (615/752),8.64％ (65/752) and 9.57％ (72/752).In 2006-2010 were 64.50％ (792/1228),6.51％ (80/1228) and 28.99％ (356/1228).In 2006-2010,the proportion of abdominal significantly decreased and laparoscopic significantly rised compared with those in 2000-2005,there were statistically significant differences (P ＜ 0.01).In 2000-2005,unilateral and bilateral annex removal ratios were 15.43％ (116/752),12.23％ (92/752),in 2006-2010 were 8.63％ (106/1228),7.49％(92/1228).Unilateral and bilateral annex removal ratios in 2006-2010 were significantly lower than those in 2000-2005,there were statistically significant differences (P ＜ 0.01 or ＜ 0.05).Conclusions Over the past 10 years,hysterectomy route and range changed with the percentage of laparoscopic increasing,and concomitant unilateral or bilateral annex removal decreased.
