Objective To study the telomerase activity,the keratinocyte apoptosis in condyloma ac-cuminatum(CA)and the correlation between them.Methods CA specimens from30patients were stud-ied,and compared with normal tissue and tumor cell lines.Telomerase activity was detected with telomeric repeat amplification polymerase chain reaction(TRAP)-ELISA.Terminal deoxynucleotidyl transferase(TdT)-mediated biotin dUTP nick end-labeling(TUNEL)was used to evaluate apoptotic cells.Results Increased telomerase activity was detected in27(90%)patients with CA,with A 450 ranging between0.50and2.76(mean1.3022).Apoptotic keratinocytes were found in24out of30CA cases(80%).A statistically signifi-cant inverse correlation was found between telomerase activity and apoptotic index(r =-0.52,P=0.004).Conclusion Keratinocyte telomerase is activated in condyloma acuminata,which is correlated with the downregulation of apoptosis,thus they might be involved in the pathogenesis of CA.

Objective To investigate the efficacy of microsurgery treatment with small craniotomy lateral fissure approach for hyperten-sive basal ganglia intracranial hemorrhage. Methods From December 2013 to February 2015, 30 patients with hypertensive basal ganglia intracranial hemorrhage ( blood loss within 30~60 mL) were analyzed respectively. Summarized the methods and techniques of this microsur-gery treatment and analyzed its advantages and disadvantages compared with the traditional operation. Results The hematomas were excluded more than 90% which were proved by reexamination after opreation. There was one case of temporal lobe infarction,but there was no re-bleed case and death case. The recovery of consciousness is good, and the limb function and language function were improved by early rehabilitation treatment. Conclusion Microsurgery treatment with small craniotomy lateral fissure approach for hypertensive basal ganglia intracerebral hemorrhage has the advantages of minimal invasion,complete hematoma removal and low complication and disability rates, which is worthy of promotion and application.

Aim To screen out the antigenic sequences from HCV core protein random peptide libraries displayed on phage and to explore a new way to screen the viral antigens. Methods The anti-HCV core antibody-positive serum was used to screen antigenic peptides from the HCV core protein random peptide libraries displayed on phage for 4 rounds. Detection of numbers of positive clones, positive rate of insertion of HCV random DNA and positive rate of hybridization with HCV core probes were used to evaluate the screening effects. The DNA sequences of 7 selected clones with positive hybridization were determined and analysed. Results Six out of 7 sequences are HCV core protein sequences, in which 5 were perfectly displayed,and one was possibly displayed. These sequences included several major HCV core antigenic epitopes. The remaining one was E.coli nrfa gene. Conclusion The phage display technique can be applied to study the viral antigenic peptides with the advantages of simple, accuracy and rapidity.

Background and purpose: Anti-tumor chemotherapy compromises normal immune function of the patients. There were many reports that chemotherapy for advanced colorectal cancer often inhibit the cellular immune function. The effect of FOLFOX regimen chemotherapy on immunity of the patients with colorectal cancer before and after therapy was studied, and healthy people were used as a control. Methods: Eighty colorectal cancer patients were treated by FOLFOX regimen, which consisted of 2-hour infusion of oxaliplatin(85 mg/m~2) and 2-hour infusion of leucovorin (CF)(200 mg/m~2) on Day 1, followed by 5-fluorouracil(5-FU) bolus (400 mg/m~2) on Day 1 and 46-hour infusion (2 400 mg/m~2). FOLFOX regimen was repeated at 2-week intervals. Two treatments of the above regimen were defined as one cycle. Flow cytometry was used to detect T lymphocyte subsets and NK cells in blood samples from patients with colorectal cancer before and after therapy. Data obtained fi'om healthy people was used as control. Results: CD3~+, CD4~+ T cells, NK cells and CD4~+/CD8~+ ratio in blood samples were not significant before and after chemotherapy in first day, second week and fourth week(P0.05). Lower CD3~+, CD4~+ T cells, NK cells and CD4~+/CD8~+ ratio were detected in blood samples from cancer group than that from the healthy control(P<0.05). CD8~+ T lymphocyte were reverse. This change was related to the TNM pathological stage. Conclusion: FOLFOX regimen was effective for patients with coloreetal cancer, which can improve patients' life quality and did not impact on the immune function of the patients. The immune function of lymphocytes in peripheral blood of the patients with colorectal cancer was low, and even worse in the patients with late TNM stage. It is valuable for estimating the function of cell immune of the patients, patients prognosis and the role of immune therapy in the treatment of the patients by detecting T lymphocyte subset and NK cell.
