[Objective]This study was aimed to evaluate treatment outcomes and toxicity of continuous-infusion EPOCH regimen for NK/T-cell lymphoma(NK/TCL).[Methods]From June 2003 to June 2008,34 patients including 30 nasal NK/TCL (88.2%)and 4 nasal type NK/TCL(11.8%)received doxorubicin,vincfistine,etoposide over 96 hours infusion with bolus eyelophosphamide and oral predinisone(EPOCH)chemotherapy as first-line treatment.Median cycles of EPOCH administered were 2.5(1-6 cycles).Additional involved field radiation therapy(IFRT)was administered to patients with localized nasal focus after chemotherapy.[Results]Among 34 patients,33 were eligible for response evaluation.The response rate(RR)was 60.6% (20/33)with complete remission(CR)rate of 45.5%(15/33).The RR of patients with nasal NK/TCL was 66.7%(20/30)with CR rate of 50%(15/30).Only one of the 3 nasal type NK/TCL patients achieved stable disease(SD),the other 2 had progressive disease(PD)during chemotherapy.After a median follow-up of 22(2-68)months,the estimated 3-year overall survival rate(OS)was 52.2%.For patients with nasal NK/TCL,the estimated median survival time was not reached,the 3-year OS was 59.4%.For patients with nasal type NK/TCL,the estimated median survival time was only 7 months.The CR rate was 75.0% for localized nasal NK/TCL who received initial EPOCH chemotherapy followed IFRT with the 3-year OS of 75.0%.Major adverse effect was myelosuppression.The incidence of grade Ⅲ～Ⅳ neutropenia was 30.9%.No treatment-related mortality occurred.[Conclusions]EPOCH regiment was effective and well tolerant for nasal NK/TCL.Combined EPOCH chemotherapy followed by IFRT produced promising outcome for patients with localized disease.However,patients with nasal type NK/TCL responded poorly and more efficacious treatment strategies are urgently needed.

[Objective]To evaluate the clinical efficacy and side effects of DHAOx±R regimen in the patients with relapsed and refractory non-Hodgkin's lymphoma(NHL).[Methods]Twenty patients with relapsed or refractory NHL were enrolled into this study in Cancer Center of Sun Yat-sen University.These patients were treated with DHAOx±R regimen(Dexamethasone 20 mg/day intravenous(Ⅳ)on day 1 to day 4,cytarabine 2 000 mg/m~2 3 h Ⅳ,every 12 hours on day 2;oxaliplatin 130 mg/m~2 2 h Ⅳ on day 1;with or without rituximab 375 ms/m~2 on day 0).Six patients were followed by high dose chemotherapy with autologous peripheral blood stem cell transplantation.Response to treatment wag assessed according to The International Working Group Criteria,including CR,PR,SD and PD.Side effects were graded according to WHO criteria,including 0-Ⅳ grades.[Results]Twenty patients received 47 cycles chemotherapy,13 patients(65%)received DHAOx chemotherapy and 7(35%)received DHAOx+R.The response rate(RR)for the whole group was 55%(11/20)with comeplete response(CR)rate 35%(7/20).The response can also be obtained in the patients who were already treated by platinum-based regimen before.The major toxicity Wag myelosuppression.The incidence of grade Ⅲ～Ⅳ neutropenia Wag 35%(16/47),and febrile neutropenia was 17%(8/47).The incidence of grade Ⅲ～Ⅳ thrombocytopenia was 20%(9/47).Eight cycles(17%)occurred mild neumtoxicity.With median follow-up of 12 months,1 and 2-year overall survival rate were 70.6%.[Conclusion]DHAOx was an effective regimen for recurrent and relapsed NHL patients with mild side effects and further investigation is needed.

Aim To observe the effects of icariin on depressive-like behavior in prenatally stressed offsprings and explore its mechanism.Methods The model of depression was established by prenatal restraint stress on late pregnant mother, then male offspring rats were randomly divided into five groups of eight: Control, PS model, Saline group(NS), ICA(80 mg·kg-1), ICA(40 mg·kg-1).The effects of icariin on PS-induced depressive-like behaviors in male offsprings were examined by forced swimming test(FST) and open-field test(OFT).Furthermore, the protein expressions of group I metabotropic glutamate receptors(I mGluRs) and excitatory amino acid transporter 2(EAAT2) in prefrontal cortex were detected by Western blot.Results PS group exhibited depressive-like behaviors with decreased struggling time(P<0.01) and center crossing numbers(P<0.05) compared to CON, with increased protein expressions of group I mGluRs(P<0.01,P<0.05) and decreased EAAT2(P<0.05) in prefrontal cortex compared to CON.Treatment with icariin(80 mg·kg-1, 40 mg·kg-1)significantly increased struggling time(P<0.05,P<0.01) and center crossing numbers(P<0.05) in PS-exposed male offspring rats.Treatment with icariin markedly modulated the protein levels of mGluR1, mGluR5 and EAAT2 in prefrontal cortex.Conclusion Icariin has significant antidepressant effects in prenatally stressed rats, and the mechanism might be associated with the modulation of Ⅰ mGluRs.

Background and purpose:Promoter methylation ofPCDH10, a gene encoding protocadherin 10, has been found to be correlated to poor prognosis in gastric cancer (GC) patients. However, the relationship between the expression of PCDH10 and prognosis in GC remained unknown. This study aimed to explore the relationship be-tween the expression of PCDH10 and clinicopathological features and prognosis of GC, and to identify biomarker for predictions of recurrence and survival of GC.Methods:mRNA expressions of PCDH10 in 115 pairs of GC tissues and adjacent normal tissues were detected by real-time lfuorescence quantitative polymerase chain reaction (RTFQ-PCR). The correlation between PCDH10 expression level and clinicopathological features and prognosis of GC was analyzed. Prediction models for 5-year recurrence and 5-year survival were established using logistic regression method.Results:Progression-free survival (PFS) and overall survival (OS) were signiifcantly prolonged in patients with PCDH10 low expression compared to patients without PCDH10 low expression (P=0.046 andP=0.033 respectively). PCDH10 low expression signiifcantly correlated with less lymph node metastasis (P=0.001) and earlier TNM staging (P=0.001), and was more common in female than in male (P=0.040). The mRNA expression of PCDH10 did not correlate with age, Lauren classiifcation, T stage, neural invasion or vascular invasion. Univariate Cox analysis showed Lauren classiifca-tion, T stage, N stage, M stage and PCDH10 expression signiifcantly correlated with PFS and OS. Logistic regression models for the prediction of 5-year recurrence or 5-year survival based on clinicopathological features included Lauren classiifcation, T stage, N stage and M stage as variables. Logistic regression models for the prediction of 5-year recur-rence or 5-year survival based on PCDH10 expression included Lauren classiifcation, T stage, M stage and PCDH10 expression level but not N stage as variables. The models based on PCDH10 expression had the same effciencies as models based on clinical parameters in predicting 5-year recurrence or 5-year survival for GC patients.Conclusion:PCDH10 low expression correlated with better prognosis, less lymph node metastasis and earlier TNM stage in GC patients. Low expression of PCDH10 may be a biomarker of better survival for GC patients. Logistic regression model based on PCDH10 mRNA expression may serve as a prediction model when patients have unknown lymph node metas-tasis status.

Objective To investigate the clinical pattern,therapeutic principle and influencing factors of interstitial pneumonia in renal allograft recipients.Method The general information,clinical manifestation,treatment and outcomes of 30 recipients with interstitial pneumonia after renal transplantation from Nov.2006 to Dec.2013 were analyzed retrospectively.Result Twenty-nine of 30 patients developed interstitial pneumonia between 2 to 6 months post-transplant.The total course of the pneumonia lasted for 34.9 ± 7.5 days on average.Chest CT scans were used to monitor severity of interstitial pneumonia each week.The mean duration between the onset to the fastigium of pneumonitis was approximately 14.8 ± 1.9 days.The mean duration of the fastigium lasted for 7.3 ±3.6 days,after that the patients usually started to recover.Deteriorated chest CT scan findings and long terms of the fastigium usually indicated poor outcomes.The mean duration of the recovery period was 13.1 ± 3.7 days.After adjusted administration of methylprednisolone,antibiotics,antifungal agents,nutritional support as well as immunosuppressive drugs,23 patients with mild and moderate pneumonia by the chest CT scans were cured and discharged.However,4 of the 7 patients with severe pneumonia by the chest CT scans died.Conclusion The progression of interstitial pneumonia after renal transplantation is characterized by a more consistent regularity.After adjusted administration of methylprednisolone,antibiotics,antifungal agents,nutritional support as well as immunosuppressive drugs,renal allograft recipients with interstitial pneumonia could obtain a good therapeutic effect without over-treatment.

Objective To assess the value of acoustic radiation force impulse (ARFI) imaging in the pathological damage of Henoch-Schonlein purpura nephritis on children by comparison with renal biopsy.Methods 50 cases of healthy control group as group A; 58 children with HSPN were divided into three groups according to pathological grading:Ⅰ ～ Ⅱ class (group B),Ⅲ class (group C) and Ⅳ ～ Ⅵ class (group D).ARFI was then used to measure the shear wave velocities(SWV) of renal cortex of each group,compared the differences SWV of each group.Results SWV values of children's renal cortex with HSPN were significantly higher (t =5.883,P =0.017) than those in the group A.Pairwise comparisons found that there were statistically significant differences between group D and the other three groups (P ＜0.05).According the ROC curve,the cut-off value of SWV was 2.59 m/s when the maximum area under the curve equal to 0.719,the sensitivity and specificity were 63％ and 67％.Conclusions ARFI technology can quantify the elastic properties of the kidney,which is expected as an important indicator to evaluate the pathological extent of damage of the HSPN.

Oxaliplatin-loaded nanostuctured lipid carriers (OP-NLC) were prepared by ultrasonic emulsification method. And its optimal prescription was selected by orthogonal design. The laser light scattering technique, zeta potential analyzer, TEM, DSC, XRD and HPLC were employed to study the physicochemical parameters of OP-NLC, which displayed in terms of particle size, zeta potential, crystalline, drug loading and encapsulation efficiency. The results showed that OP-NLC had an average diameter of (111 +/- 20) nm, zeta potential of (-27.4 +/- 13.1) mV, encapsulation efficiency of (77.4 +/- 2.5) % and drug content of (0.8 +/- 1.5) mg mL(-1). TEM, DSC and XRD indicated that OP-NLC was spherical and the drug was dispersed as nanoparticles by means of non-crystalline. The in vitro release test showed that the drug could be sustained-released from NLC in buffer solution (pH 4.5) after a burst release in initial phase.

AIM: To investigate the effects of fibroblast growth factor 10 ( FGF10 ) on lipopolysaccharide ( LPS)-induced microglial activation .METHODS:Mouse BV2 microglial cells were maintained in DMEM in a humidified incubator with 95%/5%( V/V) mixture of air and CO 2 at 37℃.The medium was changed every 1 or 2 d.The cells were digested and passaged every 4 or 5 d.The BV2 microglial cells were first pretreated with FGF 10 (1 mg/L) for 30 min and then stimulated with LPS (500 μg/L).The medium and the cells were collected at different time points .The morphologi-cal changes of microglia were visualized under microscope .To evaluate the microglial activation , the transcription and pro-duction of proinflammatory factor tumor necrosis factor-α( TNF-α) were examined by real-time quantitative polymerase chain reaction (RT-qPCR) and enzyme-linked immunosorbent assay (ELISA), respectively.RESULTS:The morphology of control BV2 microglia showed circular or oval shape .After exposure to LPS for 24 h, the microglia revealed spindle shaped or multipolar morphology , and the percentage of activated cells was significantly increased compared with control group.Pretreatment with FGF10 successfully inhibited the morphological change from normal to activated shape .LPS sti-mulation for 6 h significantly increased the transcription of TNF-α, while FGF10 pretreatment remarkably reversed the effect.In addition, the production of TNF-αincreased in the presence of LPS stimulation for 24 h compared with control group.Pretreatment with FGF10 suppressed LPS-induced TNF-αexpression.CONCLUSION: Pretreatment with FGF10 inhibits the morphological change from normal to activated shape , and remarkably suppressed the transcription and produc-tion of TNF-α.FGF10 successfully suppresses LPS-induced BV2 microglial activation , indicating that FGF10 is a therapeu-tic agent for the treatment of glia-mediated neuroinflammatory diseases .
