Background and purpose:The patients with aggressive lymphoma who have a poor prognosis and unlikely to be cured with conventional chemotherapy. This study was aimed to evaluate the effect of high-dose etoposide in mobilization followed auto-SCT in treating refractory lymphoma. Methods:40 patients [median age 33 (13-61) years] with refractory non-Hodgkin’s lymphoma (NHL, n=32) or Hodgkin’s lymphoma (HD, n=8) received high-dose etoposide [VP16 10-15 mg/(kg·d)×2 d] in mobilization in our center. Remission status prior to mobilization was PD (n=40). The use of such granulocyte colony-stimulating factor [G-CSF, 5-10μg/(kg·d)] mobilized peripheral blood stem cells (PBSC) after high-dose etoposide until the end of leukapheresis. Peripheral blood stem cell was collected and frozen in-80℃refrigerator. All these patients received auto peripheral blood stem cell transplantation (auto-PBSCT). Conditioning regimen was BEAM (n=19, 47.5%) or CBV (n=21, 52.5%). Results:Twenty-eight pa-tients (70%) were assessable for response after high-dose etoposide at a median pretreatment time of 39 days (range 17-172 days), 12 patients (30%) had no response. Median follow-up of 28 (4-66) months, 16 patients (40%) reached CR after auto-PBSCT. Fifteen of the 28 patients (53.6%) who had response to high-dose etoposide reached CR, 4 patients (14.3%) reached PR, 9 patients (32.1%) succumb to progression of disease. One of the 12 patients (8.3%) who had no response to high-dose etoposide reached CR, 1 patients (8.3%) reached PR, 10 patients (83.4%) succumb to progression of disease. The estimated 1-year OS and EFS were 69%and 56.7%respectively, 2-years OS and EFS were 63%and 52%respectively. The prognosis of the patients who had no response to etoposide was poor. The estimated 1-year OS and EFS were 25%and 16.7%respectively. Two group of comparison differences have statistics signiifcance (P<0.01). Conclusion: High-dose etoposide could be used in refractory lymphoma as rescue therapy in mobilization. It can increase the EFS and OS of patients who had response. The hematopoietic stem cells collection and hematopoietic reconstitution are not affected by etoposide.

OBJECTIVETo evaluate the therapeutic effect of Longjintonglin Capsules on type IIIA prostatitis accompanied by abnormal semen liquefaction.

METHODSWe selected 140 patients with type IIIA prostatitis accompanied by abnormal semen liquefaction according to the diagnostic standards of the American Institutes of Health (NIH) and treated them with Longjintonglin Capsules orally 3 capsules once tid for 12 weeks. We obtained the NIH Chronic Prostatitis Symptom Indexes (NIH-CPSI), traditional Chinese medicine (TCM) syndrome scores, leukocyte count in the expressed prostatic secretion (EPS), semen liquefaction time, and the results of semen analysis and compared these indicators before and after the treatment.

RESULTSOf the 140 cases, 132 were included in this study, excluding 8 due to their incomplete case histories. Before and after 4, 8 and 12 weeks of medication, the total NIH-CPSI scores were 24.52 ± 5.43, 21.28 ± 4.85, 18.01 ± 4.28, and 14.49 ± 3.65 (P < 0.01), the TCM syndrome scores were 35.63 ± 6.07, 26.66 ± 5.03, 17.37 ± 4.18, and 11.11 ± 3.96 (P < 0.01), and the leukocyte counts (/HP) were 27.50 ± 7.01, 22.38 ± 5.22, 16:76 ± 4.10, and 11.40 ± 4.74 (P < 0.01), respectively. After 12 weeks of treatment, 31 of the patients with type IIIA prostatitis were cured and another 72 well responded, with an overall response rate of 78.0%. Of those with abnormal semen liquefaction, 61 were cured, 39 well responded, and 32 failed to respond, with an overall effectiveness rate of 75.8%. Semen analysis showed significantly increased percentage of progressively motile sperm after 4, 8 and 12 weeks of medication as compared with the baseline (P < 0.01). No abnormal liver or renal function or other adverse reactions were observed during the treatment.

CONCLUSIONLongjintonglin Capsules, with its advantages of safety, effectiveness and no obvious adverse effects, deserve to be recommended for the treatment of type IIIA prostatitis accompanied by abnormal semen liquefaction.

Objective To examine the distribution of bacterial species and antimicrobial susceptibility profile of pathogens in febrile neutropenic patients.Methods A total of 355 bacterial strains were isolated from febrile neutropenic patients in Shanghai General Hospital from January 2005 to December 2012. Antimicrobial susceptibility testing was done by Kirby-Bauer method. The susceptibility testing results were analyzed according to CLSI 2014 breakpoints.Results Gram-negative bacteria accounted for 70.4% of the 355 isolates, while gram-positive organisms accounted for 29.6%. The most common bacterial species werePseudomonas aeruginosa, Klebsiella pneumoniae, Acinetobacter baumannii, Escherichia coli, Stenotrophomonas maltophiliaand Staphylococcus haemolyticus. Non-fermentative bacteria accounted for 53.2% of all the gram-negative bacterial isolates. All theEnterococcus and
Staphylococcus isolates were susceptible to linezolid, vancomycin and teicoplanin. All theStaphylococcus strains were resistant to methicillin.P. aeruginosa isolates were relatively more susceptible to cefoperazone-sulbactam, piperacillin-tazobactam and cefepime (>70%) than imipenem (40.8%) and meropenem (59.2%). All theK. pneumoniae isolates were susceptible to imipenem and meropenem and more than 70% of the isolates were susceptible to cefoperazone-sulbactam, amikacin. More than 80% of theA. baumannii isolates were susceptible to carbapenems, cefoperazone-sulbactam, amikacin, ciprolfoxacin and aminoglycosides. All the E. coli isolates were susceptible to carbapenems and more than 70% were susceptible to cefoperazone-sulbactam and ceftazidime. More than 90% of theS. maltophilia strains were sensitive to levolfoxacin, minocycline, cefoperazone-sulbactam and trimethoprim-sulfamethoxazole.Conclusions Our data suggest that gram-negative bacteria, especiallyEnterobacteriaceae and non-fermentative bacteria, are still the primary pathogens in febrile neutropenic patients. Antimicrobial resistant strains are prevalent. Such data of bacterial species and antimicrobial susceptibility proifle of pathogens in febrile neutropenic patients are useful for empirical antimicrobial therapy of such infections.

AlM:To find better ways of treating ocular alkali burn, and to reduce the suffering of patients and social burden.METHODS:Totally 100 patients were graded according to the degree of chemical burns to four major groups, each half were randomly divided into the control group and the treatment group. Control group underwent conventional treatment. ln addition to conventional therapy, patients in each treatment group were also added a Breviscapine intravenous injection of 40mg daily. Corneal recovery time, changes in vision, degree of corneal opacity, number of corneal neovascularization and other complications were observed. Curative effects were analyzed statistically.
RESULTS:There was no significant difference in levelⅠgroup between control group and treatment group ( P>0. 05); There were significantly different in level Ⅱ, Ⅲand Ⅳ group ( P<0. 05 ). Compared to the degree of corneal opacity and the number of corneal neovascularization, the treatment group was obviously better than the control group(P<0. 05).
CONCLUSlON: Breviscapine in the treatment of ocular alkali burns can shorten the course of treatment, reduce corneal scarring, and improve vision.

Objective To construct cDNA entry library and cDNA expression library of Armillifer agkistrodontis (A.) nymphs and make a preliminary immunoscreening for the cDNA expression library.Methods The nymphs were collected from the Kunming mice infected experimentally with A.agkistrodontis eggs and the total RNA were extracted from the nymphs using TRIzol Reagent.After purifying the mRNA,the synthesized cDNAs were cloned into the donor vector pDONR222 by BP reaction of Gateway technology and the recombinants were transformed into the DH10B cells by electroporation,the cDNA entry library was obtained.Next,the expression vector pDEST17 was ligated with entry clones by LR reaction,and the recombinants were transformed into the BL21 (DE3) cells.Hence,the cDNA expression library was constructed.Then,the expression library was immunoscreened with the mixed sera of mice infected with A.agkistrodontis,and the insertions of positive clones were sequenced.After that,the open reading frame(ORF) of positive slone sequence,the homology of the screened genes and their encoded proteins were analyzed by Finder and BLAST (basic local alignment search tool) program of National Center of Biotechnology Information(NCBI),and the discovered new genes were submitted into the GenBank.Besides,the physico-chemical properties,secondary structure and B cell epitopes of encoded proteins were also analyzed by bioinformatics software.Results The average titer and total clones of the cDNA entry library were 1.45 × 105 CFU/ml(colony-forming unit,CFU) and 1.74 × 106 CFU,respectively,and the range of fragment length of the inserted cDNA was between 0.2-4.0 kb,with an average of 1.4 kb.The total clones of cDNA expression library were 1.00 × 105 CFU,and the fragment length of the inserted cDNA was between 0.3-2.2 kb,with an average of 1.0 kb.Five positive clones,coded S1,S5,A1,D1 and F1,respectively,were obtained through preliminary immunoscreening.The sequence and homology of the five positive clones were sequenced and analyzed by BLAST program.No significant similarities were found in pentastomida species,which meant that they were all novel genes of A.agkistrodontis.The gene sequences were submitted to GenBank,with the accession number from JQ180451 to JQ180455.Also,results obtained by bioinformatics software showed that the predictive encoding proteins were all potential to be valuable recombinant diagnostic antigens.Conclusions The cDNA library of A.agkistrodontis nymphs is successfully constructed,and five new genes of A.agkistrodontis are discovered.The establishment of cDNA library and the discovery of the new genes will lay a foundation for further studying the gene functions and screening the immunodiagnostic antigens.

Objective To evaluate the response rate and survival rates of refractory or relapsed Hodgkin lymphoma (HL) and grey zone lymphoma patients treated with autologous peripheral blood stem cell transplantation (APBSCT).Methods From January 2004 to August 2012,30 HL and grey zone lymphoma patients were retrospectively analyzed.Statistical analysis was done to explore the long term outcome and prognostic factors of patients treated with APBSCT.Among all patients,the median age at transplantion was 30 (13-55) years old.Patients were major with nodular sclerosis HL and in stage Ⅲ/Ⅳ.Results Every patient had a successful collection.The median MNC cell dose infused was 6.8×108/kg [range (1.0-13.8)×108/kg] and median CD34+ cell dose infused was 6.3×106/kg [range (0.6-20.6)×106/kg].Median time to neutrophil engraftment was 9 days (range 8-12 days).28 patients were evaluable after transplantation with a median follow-up of 18.5 months (range 2.5-95.0 months).The overall response rate was 89.3 ％ [CR 64.3 ％ (18/28),PR 25.0 ％ (7/28)].The overall survival (OS) rate and progression free survival (PFS) rate at 5 year would be 78 ％ and 58 ％ for all patients.3 in 7 patients with no remission after salvage chemotherapy with rituximab plus chemotherapy before APBSCT got CR and 2 got PR.Univariate analysis showed that disease status and the number of replacement types of chemotherapy prior to transplantation affected OS,the history of radiotherapy prior to transplantation affected PFS.Conclusion APBSCT can increase CR rate,prolong survival time in patients with refractory or relapsed HL and grey zone lymphoma.Rituximab plus chemotherapy as a salvage therapy could raise CR rate before APBSCT.Chemosensitivity before transplantation affect outcome with APBSCT.Changing many types of chemotherapy is adverse for APBSCT.Salvage radiotherapy before APBSCT is not recommended.

Objective To evaluate the efficacy of anti-CD20 monoclonal antibody (Rituximab) combined with autologous hematopoietic stem cell transplant (ASCT) in treatment of the patients with B cell non-Hodgkin lymphoma (NHL). Methods Twenty-one patients with B-cell NHL(CD20 positive) received ASCT with Rituximab at the dose of 385 mg·m-2·d-1 on day 1 and day 8 of mobilization,and day -1 and day +7 of conditioning regimen. Among the 21 patients receiving chemotherapy before the transplant, five cases achieved complete response (CR), eleven cases achieved partial remission (PR), and 5 cases had the progression of disease (PD) after many cycles of chemotherapy. Results The median follow-up was 24 months (1-68 months) in the present study. No relapse occurred among the 5 patients in CR before the transplant. Only one of the 11 PR patients relapsed 6 months post-transplantation. Three of the 5 PD patients died. Four of 21 cases (19 %) were documented as recurrence and death, the other 17 cases remained alive and disease-free. Both 2-year EFS and OS of these cases were 81%. No harmful effect of Rituximab was observed on the quality and quantity of collected stem cells as well as hematopoietic recovery post SCT. Conclusion The efficacy of ASCT with Rituximab in vivo purging in the patients with B-cell NHL was determined mainly by the disease status before transplant. The approach may be used as consolidation therapy to achieve long-term survival and increase the curable rate for patients in CR before transplant, and as intensification therapy to increase the remission rate and prolong the EFS and OS of the patients in PR. Rituximab did not show any adverse effect on collection and reconstitution of hematopoietic stem cells.

Objective:To investigate the expression of wild type estrogen receptor(wER)and the ex-on-5 deleted ER(variant ER,vER)in human hepatocellular carcinoma(HCC)samples,and thereafteranalyze the possibility of HCC treatment by endocrine therapy.Methods:The mRNA expressions of wERand vER were analysed from 28 cases of HCC by RT-PCR.The expression of ER at the protein level wasdetected by immunohistochemistry(IHC).Results:IHC results showed that 39.3% of the HCC speci-mens expressed ER.The mRNA of wER was detected in 89.3%(25/28)of the HCC specimens whilethat of vER was detected in 96.4%(27/28).Twenty four out of 28 HCC cases(85.7%)expressedboth wER and vER.One out of 28 patients(3.5%)expressed only wER whereas 3 patients out of 28(10.7%)expressed vER only.Conclusion:Ninety six percent(27/28)of the HCC patients expressedvER,which suggests that the expression of vER is an important event in the development of HCC.
