OBJECTIVETo construct a replicative anti-tumor DNA vaccine PSCK-2PFcGB based on Semliki Forest Virus (SFV) replicon vector and observe its expression in vivo and in vitro.

METHODSThe plasmid pVAX1-2PFcGB was digested with Nhe I, and the digestion product was blunted prior to further digestion with BssH II to obtain the fragment 2PFcGB, a fusion gene containing the multitarget complex antigen 2PAG encoding both the most cytotoxic T lymphocyte epitopes of human survivin and chorionic gonadotropin β chain-CTP37 of human and monkey. The 2PFcGB fragment was inserted into the PSCK vector digested by Sma I. The products with the expected size were extracted and ligated, and the positive clones were screened by kanamycin and amplified. The recombinant PSCK-2PFcGB, following identification by colony PCR and restriction endonuclease Nde I, was transfected into 293T cells via lipofectamine 2000 and its expression was detected. The recombinant plasmid was also transfected into mouse quadriceps femoris muscle to observe its expression in vivo by immunohistochemistry.

RESULTSNde I digestion resulted in a fragment of the expected size. Transfection with the recombinant plasmid PSCK-2PFcGB resulted in successful expression of the antigen and adjuvant molecular protein in 293T cells, with the positivity rates of 5.70% and 19.75%, respectively. The fusion tumor antigen survivin and hCGβ-CTP37 were also detected in the muscular tissues of the mice.

CONCLUSIONA novel replicative anti-tumor DNA vaccine PSCK-2PFcGB has been successfully constructed and can be expressed in 293T cells and in the muscular tissues of immunized mice, which provide a basis for further studies of the antitumor activity and immunological mechanism of the DNA vaccine.

OBJECTIVETo explore the clinical effects and safty of manipulative reduction with percutaneous poking K-wire fixation for the treatment of the calcaneus fractures and analyze the indication of the minimal invasion.

METHODSFrom December 2008 to December 2011,135 closed calcaneal fractures cases were divided randomly into poking group and plate group, treated respectively by percutaneous poking reduction and operative reduction. In poking group, there were 69 cases (82 feet) including 60 males and 9 females, with an average age of (43.29+/-10.46) years ranging from 18 to 64 years; 30 cases of left, 26 cases of right and 13 cases of double; 54 feet of Essex-Lopresti classification tongue form, 28 feet of joint compression; 33 feet of Sanders type II ,49 of type III. In plate group, there were 66 cases (75 feet) including 58 males and 8 females,with an average age of (46.00+/-2.42) years ranging from 21 to 63 years; 31 cases of left, 26 cases of right and 9 cases of double; 48 feet of Essex-Lopresti classification tongue form, 27 feet of joint compression; 28 feet of Sanders type II, 47 of type III. According to Kerr scoring standard,clinical effects and complications were evaluated combining with Sanders and Essex-Lopresti classification.

RESULTSAll 135 cases were followed up after 24 weeks. Fractures were recoveried in 8 to 12 weeks (means 10.2 weeks). In poking group, there were 2 cases of infection, 5 cases of wire movement; in plate group,18 cases of wound local skin necrosis, 5 cases of calf intestines nerve injured; there were statistical significant (P<0.05). Postoperative evaluation of Sanders type II after 24 weeks, the proportion of excellent results was above 70%,and there were no significant differences on effects of tongue form and compressing form of calcaneus fractures with percutaneous poking and operative redution (P>0.05). In the caes of Sanders type III, there were no significant differences on effects of tongue form fractures with percutaneous poking and operative reduction (P>0.05). There were significant differences on effects and complications of compressing form fractures (P<0.01), operative reduction better than percutaneous poking. Pain, walking,Kerr scoring of tongue form fractures of Sanders II , III with poking reduction were better than compression fractures. In compression fractures of Sanders Ill, plate internal fixation was better than poking redution in working and walking function, there were significant difference (P<0.05).

CONCLUSIONFor tongue form or compressing form of Sanders type II and tongue form of Sanders type III, manipulative reduction with percutaneous poking K-wire fixation has advantages of minimal invasion, minimized complications. Compressing form of Sanders type III fracture should be treated with operative redution.

OBJECTIVESTo explore the effects of E-selectin, ICAM-1 and their ligands on the adhesive metastasis of hepatocellular carcinoma (HCC), and to select possible anti-adhesion drugs for hepatocellular carcinoma metastasis.

METHODS78 HCC patients were analyzed with the correlation of clinical features to the expression levels of E-selectin, sLeX, sLeA and CD44v6 in the tumor tissue. The adhesion between HepG2 and endothelial cell lines was examined by solid phase adhesion assay in vitro. Two kinds of drugs were accessed for their anti-adhesion ability.

RESULTSThe positive rate of E-selectin in vascular endothelia cells adjacent to cancer nest is 70.51%, and which of sLeX, sLeA, CD44v6 within tumor cells is 64.10%, 69.23%, 62.90% respectively. The patients' life span is closely related with the positive expression of sLeX, sLeA, CD44v6 (P = 0.008, 0.001, 0.022). The positive expression of E-selectin, sLeX and sLeA is significantly correlated to portal vein tumor thrombus (PVTT), preoperative extrahepatic metastasis, and satellite foci, but not to the size of tumor and AFP. The level of CD44v6 expression is significantly correlated to patient's survival time. The expression levels of E-selectin and ICAM-1 are remarkably higher after ED25 and ECV304 cell lines be activated. Meanwhile the adhesive ability of HepG2 to endothelial cell is mediated. Dexamethasone, tanshinone IIA are able to block this adhesion at low concentration.

CONCLUSIONThe expression levels of E-selectin, sLeX, sLeA and CD44v6 are closely correlated with clinical features. E-selectin, ICAM-1 and their ligands are important molecules of hepatocellular carcinoma and endothelial cells to tumor adhesive metastasis. Dexamethasone, tanshinone II A can be hopefully used as anti-adhesion drugs.

OBJECTIVETo evaluate the safety, effectiveness, and outcomes of holmium laser enucleation of the prostate (HoLEP) for patients with symptomatic enlarged prostate after 11 years of experience.

METHODSThe 3162 evaluable patients treated with holmium laser enucleation of the prostate at our institution between August 2001 and August 2011 were retrospectively analyzed. Study variables included International Prostate Symptom Score, quality of life, maximum urinary flow rate, and incidence of complications.

RESULTSHoLEP were performed successfully completed, not patients which occurs as electric cutting syndrome. The operation time was (60.8 ± 18.4) minutes; average resection of prostate quality was (45.4 ± 24.4) g. The hemoglobin reduce though surgery was (1.81 ± 0.93) g/L; percentage of red blood cell change was 1.24% ± 0.43%, and sodium blood drop was (1.14 ± 0.35) mmol/L. Postoperative patients of hospital stay (3.1 ± 1.1) days, average time of indwelling catheter time was (2.3 ± 0.8) days. Patients were followed up for 6-131 months time, an average of 32.4 months. Postoperative patients with international prostate symptom score progressive declined. The quality of life score was 2.2 ± 1.7, and it less than preoperative (5.7 ± 3.3, t = 2.447, P < 0.01). The time of follow-up droped further, and postoperative comparative differences have statistical significance (t = 2.179, 2.228, 2.306 and 2.365, P < 0.05). The maximum urinary flow rate also improved (P < 0.05). Postoperative complications included bladder neck contracture (4 cases), urinary tract infection (107 cases), urethral stricture (11 cases) and urinary incontinence (11 cases). The 11 patients reoperation.

CONCLUSIONSHoLEP treatment of benign prostatic hyperplasia could achieve the advantages of open surgery the same effect. It had fewer damage, faster recovery, fewer complications, and is a good treatment option.

Ribosomal proteins are key elements of protein synthesis machinery, ribosome. Besides the essential role in ribosome assembly and protein synthesis, there are lots of extraribosomal functions for ribosomal proteins, ranging from regulating cell proliferation and apoptosis to mediating DNA repair, cellular development and differentiation. Based on the typical features of hematologic system, the ribosomal proteins are related with many hematologic diseases, such as Diamond-Blackfan anemia, 5q- syndrome. In this review, the recent research progress on extraribosomal functions and related hematologic diseases are summarised.

OBJECTIVETo investigate pathologic and differential diagnostic features of pediatric Burkitt lymphoma (BL).

METHODSA total of 20 cases of pediatric BL were retrospectively reviewed for their clinical and pathologic profiles. Bone marrow aspiration specimens were available in all cases and bone marrow biopsies were available for immunohistochemical study in 18 cases. Flow cytometry study was available in 16 cases. MYC translocation by FISH method was performed in 11 cases.

RESULTSAtypical lymphocytes with cytoplasmic vacuoles were found in bone marrow smears in all 20 cases and peripheral blood films in all 19 available cases. The bone marrow biopsies showed infiltration by uniform medium-sized atypical lymphocytes with multiple small nucleoli but without the starry-sky pattern in all 18 cases. Immunohistochemistry showed the following results in all 18 cases: positive for CD20, PAX-5, CD10, CD34 and TdT, but negative for bcl-2 and CD3 with Ki-67 > 95%.Flow cytometry showed CD19+CD20+CD10+FMC7+CD22+TdT-CD3- in 16 cases, including κ+ in 8 cases, λ+ in 7 cases, and κ-λ- in 1 case. MYC gene rearrangement by FISH was observed in 10 of the 11 cases.

CONCLUSIONSThe histopathology of BL is distinct, including atypical lymphocytes with cytoplasmic vacuoles in bone marrow aspirate, lack of starry-sky patternin bone marrow biopsy. Generally, the diagnosis should be made with a combined immunophenotype and FISH approach. Pediatric BL must be distinguished from DLBCL and B-cell lymphoma, unclassifiable, which has intermediate features between DLBCL and Burkitt lymphoma.
