Peripheral T-cell lymphomas (PTCLs) are a kind of non-Hodgkin's lymphoma (NHL),which arise from heterogeneous mature T-lymphocyte and include a variety of different subtypes.Compared with B-cell lymphoma,PTCLs are characterized by a lower incidence,resistance to conventional chemotherapy,widespread dissemination,a higher recurrence rate and unfavorable prognosis.At present,the standard first-line treatment regimens have not yet been developed for PTCLs.Though,there are many studies and trials about new drugs and novel intensive regimens,which improve the clinical curative effects and prognosis of PTCL patients significantly.In this paper,the progress of first-line treatment regimens of patients with different PTCL subtypes was reviewed.

Purpose:To compare the therapeutic effect and significance of different drugs poured in intravesical instillation for superficial biadder tumor after transurethral resection of bladder tumor.Methods:117 patients of superficial bladder cancer after transurethral vesection were divided into four groups. Ballistocardiogram group(n=26);Mitomycin C group (n=27);adriamycin group (n=27);hydroxycamptothecin group(n=37).Results:The tumor recurrent rate in Ballistocardiogram group, mitomycin groups, adriamycin group, hydroxycamptothecin group were 30.77%,40.74% 33.33%,24.32% respectively. The tumor recurrent rate differed significantly between the hydroxycamptothecin group and the mitomycin and Adriamycin groups.Conclusions:Intravesical instillation of hydroxycamptothecin for patients with superficial bladder tumor after transurethral resection of bladder tumour could decrease tumor recurrent rate, prolong the tumor-free survival period.

Objective To study the trends over time in meningococcal meningitis with Neisseria meningitidis .Methods Routine reported data on Meningococcal meningitis with Neisseria meningitidis in Shijiazhuang from 1949 to 2014 were used to study the trends of disease severity,disease distribution and serogroup switching of Neisseria meningitidis strains over time.The qualitative description and the quantitative evaluation was performed by the annual percent change (APC)in incidence to demonstrate the secular trends.The t test and χ2 test were performed when appropriate.Results From 1949 to 2014, 53 779 meningococcal meningitis cases were reported in Shijiazhuang.Of the 53 779 cases,36 170 were male and 17 609 were female,which was significantly different (χ2 =581 .04,P =0.000).It occurred all the year round,with an increased incidence between February and April,accounting for 81 .44%.The epidemic peak occurred about every 10 years.The range of annual incidence rate was from 0.01/lakh to 387.21/lakh.APC was -4.65 (t=-11 .72,P =0.000).The significant decline of APC were found in the age group of 0—1 year (t=-10.56,P =0.000),1 —5 year (t =-14.32,P =0.000),5 —10 year (t=-11 .01 ,P =0.003 ),10—15 year (t = -8.34,P =0.033 )and 40—50 year (t = -7.42,P =0.045).The risk population was those under 5 years old during 1949 to 2002 period and the serogroup was dominated by A strains.Whereas during 2003 to 2014,that was those of 5 —15 years old,and the dominant serogroup was C strains. Conclusions There is a remarkable decline in incidence of meningococcal meningitis in Shijiazhuang.The serogroup changes from A strains to C strains and the risk population of cases shifts to older children.

Objective To study the pathologic changes of hippocampus during the model development and explore the mechanism of epileptogenesis by observing the morphologic changes of hippocampal formation in rat of kainate-induced chronic temporal lobe epilepsy (TLE). Methods Thirty Wistar rats were injected of Kainic acid at dose of 2 ?g/20 ?l into the lateral cerebral ventricle under the guidence of stereotactic technique to make a epileptic focus, and subgrouped under acute phase, silent period and chronic phase. Another 10 rats received normal saline as controls. The rats were killed at 1 day, 15 day and 6 months after epileptic model establishment, and the hippocampus was taken out for HE staining, TUNEL staining, Timm’s staining, NSE staining. Results By cell counting, the neuron loss mainly occurred in acute phase, worst in CA3 and CA4, moderate in CA1 and CA2, and no loss in the dentate gyrus. The cell apoptosis in hippocampal structure was detected by TUNEL staining. Timm’s staining showed that mossy fiber began sprouting in silent period and increased continuously. Conclusion The morphologic changes of hippocampal formation in rat of kainate-induced TLE is mainly the neuron loss and the glia hyperplasy.

Objective:To evaluate the clinical efficacy of paclitaxel combined with epirubicin neoadjuvant chemotherapy in the treatment of triple negative breast cancer and the effect on the Ki-67,p53,P-glycoprotein (P-gp) and glutathione transferase (GST-π).Methods:84 patients with triple-negative breast cancer admitted in our hospital from June 2010 to June 2012 were selected and divided into the observation group and the control group according to the order of admission.The control group was treated with epirubicin,and cyclophosphamide.The observation group was given paclitaxel neoadjuvant chemotherapy combined with epirubicin.The clinical efficacy,expressions of Ki-67,p53,P-gp and GST-π were compared between the two groups.Results:After treatment,the total remission rate of observation group was significantly higher than that of the control group [76.19％(32/42) vs 45.24％(19/42)] (P ＜0.05).Before chemotherapy,the positive expression rates of Ki-67,p53,P-gp and GST-π in the two groups showed no statistical difference(P＞0.05).After chemotherapy,the positive expression rates of Ki-67,p53,P-gp and GST-π in the observation group were significantly lower than those of the control group (P＜0.05),but the positive expression rates of Ki-67,p53,P-gp and GST-π in the control group had no significant difference compared with those before chemotherapy (P＞0.05).The positive expression rates of Ki-67,p53,P-gp and GST-π in the observation group were significantly lower than those of the control group (P ＜0.05).There was no significant difference in the incidence of adverse reaction rate between the observation group and the control group (P＞ 0.05).Conclusion:Paclitaxel combined with Epirubicin neoadjuvant chemotherapy could effectively reduce the expression of Ki-67,p53,P-gp and GST-π in triple-negative breast cancer with exact clinical efficacy.

Objective To assess the value of combined detection of enterovirus nucleic acid and antibody in early etiological diagnosis for hand-foot-and-mouth disease ( HFMD).Methods A case-control study was conducted.A total of 1 066 cases of children clinically diagnosed with HFMD from Hangzhou Children′s Hospital were involved into the research group from January to June 2014, consisting of 401 common cases and 665 severe cases; Throat swabs and serum samples from these children underwent combined detection for EV71/CA16/EV of enterovirus nucleic acid by fluorescence quantitative RT-PCR and for EV71/CA16-IgM by ELISA.All data were analyzed with SPSS 16.0.Results The total positive rate of enterovirus nucleic acid EV71/CA16/EV by fluorescence quantitative RT-PCR in the 1 066 cases of children clinically diagnosed with HFMD was 75.52%( 805/1 066 ) ( 95%CI: 72.80%-78.05%).But the total positive rate of combined detection was 91.46%( 975/1 066 ) ( 95%CI:89%.58-93.04%).The total positive rate of combined detection is higher than that of RT-PCR test(χ2 =98.338,P=0.000).The positive rate of EV71 type of combined detection was 64.63%(689/1 066)(95%CI:61.67%-67.49%),which is 15.38%higher than that of RT-PCR test 49.25%(525/1 066)(95%CI:46.21%-52.29%)(χ2 =51.453, P=0.000).In 665 severe cases of HFMD, the total positive rate of combined detection was 96.69%(643/665)(95%CI:94.95%-97.87%), which is higher than that of RT-PCR test 79.25%(527/665)(95%CI:75.92%-82.22%)(χ2 =95.607, P =0.000).In the severe cases, the positive rate of EV71 type of combined detection was 87.52%( 582/665 ) ( 95%CI:84.71%-89.89%) , which is 18.95% higher than that of RT-PCR test 68.57%(456/665) (95%CI:64.87%-72.06%) (χ2 =69.665, P=0.000).In the fatal cases, the positive rate of EV71 type of combined detection was 95.92%(94/98) (95%CI:89.28%-98.68%).Conclusions The combined detection of enterovirus nucleic acid and specific IgM antibody can significantly increase the positive rate of HFMD, especially for severe cases.The combine detection increases both the total positive rate and EV71 positive rate.Thus it has a high potential for becoming a new guidelines for laboratory diagnosis of HFMD.

[Objective] To assess the predilection age,clinical features,treatment and pognostic factors of primary cutaneous B-cell lymphoma (PCBCL).[Methods] A total of 31 patients with PCBCL were registered in Tianjin Cancer Central Registry from January 1970 to September 2010,and 26 patients had complete medical recortds.A retrospective analysis was conducted on the 26 patients.The following indices were analyzed,including gender,age,body sites of initial involvement,extent of cutaneous involvement,pathological subtypes,metastatic sites,treatment,survival and prognosis.Data were processed with SPSS16.0 software,survival analysis was carried out by using Kaplan-Meier method,univariate analysis of prognostic factors by Log-rank test,multivariate analysis of prognostic faetors by COX proportional hazards model,and variables were selected by Forward LR method.[Results] Clinical manifestafions were atypical in these patients.The ratio of man and women was 1:1.6.Of the 26 cases,12 were primary cutaneous follicle-center lymphoma (PCFCL),8 were primary cutaneous marginal zone lymaphoma (PCMZL),and 4 were PCLBCL,leg type.Follow-up revealed lymph node involvement in 8 patients (4 in cervical nodes and 4 in inguinal nodes),distant metastasis of organs in 3 patients ( 1 in lung and pleura,1 in bone marrow and 1 in central nervous system).Most patients received surgical treatment combined with chemotherapy or chemoradiation.The 5-year overall survival rate was 80.8％(21/26).Statistical analysis showed that the prognosis of PCBCL was associated with histological subtype,lactate dehydrogenase (LDH) level and globulin level,but unrelated to gender,age,site of initial involvement,extent of cutaneous involvement,involvement of lymph nodes and organs,presence of B symptoms,treatment strategies,number of relapses,level of β2-globulin and hemoglobin,or lymphocyte absolute value.[Conclusion]s PCBCL,as a kind of rare extra-nodal lymphoma,usually occurs with atypical clinical mainfestations in persons aged from 39 to 66 years.The 5-year overall survival rate was 80.8％ in these patients.The prognosis of PCBCL seems to be related to histological subtypes,LDH and globulin levels.

Objectives To investigate the clinical features,diagnosis,treatment and prognosis of primary hepatic lymphoma (PHL).Methods A retrospective study was carried out on the clinical records of 6 patients with primary hepatic lymphoma (PHL) treated at the Tianjin Medical University Cancer Hospital from April 2005 to September 2010.The domestic and foreign medical literatures were reviewed.Results For the 6 patients with PHL,the median age was 57 years (range 31-78 years).The male-to-female ratio was 2: 1.The most common initial symptoms were abdominal pain and fever.Serum transaminase,lactate dehydrogenase and β2-microglobulin levels were elevated in 4 of 6 patients.For the 3 patients who were tested for alpha-fetoprotein and carcinoembryonic antigen levels,the results were normal.None of the patients had a history of hepatitis or cirrhosis.The diagnosis was non-Hodgkin's lymphoma.A R0 resection was carried out in 1 patient who was lost to follow-up soon after surgery.A R2 resection was carried out in another patient.The remaining 4 patients received liver biopsy.Five patients were treated by CHOP or CHOP-like chemotherapy.A patient died of brain metastases after 8 cycles of chemotherapy,and another patient was lost to follow-up after 1 cycle of chemotherapy.Chemotherapy combined with rituximab were given to the other 3 patients.There was a complete remission in 2 patients after chemotherapy and biotherapy,and these patients were still alive at the last follow-up.Partial remission was achieved in the remaining patient after chemotherapy.The patient was given radiotherapy,but he died finally of tumor progression.Conclusions PHL is an extremely rare lymphoma.Its clinical presentations and imaging manifestations are non-specific.PHL should be considered when the patient has abdominal pain or fever,with a mass in the liver.The ultimate diagnosis depends on histopathologic examination.The pathological type is mainly non Hodgkin's lymphoma,with diffuse large B cell lymphoma.There is still no standard treatment.Surgery,chemotherapy,radiotherapy,targeted therapy and biotherapy can be used.

Objective To study the clinical features, effects of therapeutic regimen and prognosis of patents with mantle cell lymphoma (MCL). Methods Clinical data of 27 MCL patients admitted in Tianjin Medical University Cancer Institute&Hospital from January 2008 to December 2014 were retrospectively analyzed. Cox regression analysis was used to analyze influencing factors of prognosis of MCL. Results The median age was 68 years old for 27 patients, and the male-to-female ratio was 4.4∶1. Ann Arbor staging showed that 25 cases were stageⅢ-Ⅳ(92.6%), 8 cases were heptosplenomegaly (29.6%), 7 cases showed extranodal involvement (25.9%). ECOG scoring showed that 4 cases with scores of 2-4 (14.8%), 8 cases were 0-3 (29.6%), 14 cases were 4-5 (51.9%) and 5 cases were 6-11 (18.5%). The Ki-67 index≤30%was found in 9 cases (33.3%), and>30%was found in 18 cases (67.7%). Patients with B symptom was found in 10 (37.0%). The elevated lactate dehydrogenase (LDH) was found in 17 cases (63.0%). The increased Beta 2- microglobulin was found in 8 cases (29.6%). Seven patients were found with bone marrow involvement. The total effective rate (ORR) was 81.8%in group with R-CHOP method, and the ORR was 68.8%in group with CHOP method. Multivariate analysis showed that age, LDH and Ki-67 were independent factors influencing the prognosis of MCL (P<0.05). Conclusion Most patients with MCL are found in advanced stage. Patients with age>60 years, elevated LDH and Ki-67 index>30%are with poor prognosis.
