Objective To investigate the effects of Livin antisense oligonucleotide (ASODN) on the proliferation and apoptosis of human leukemia (K562) cells. Methods Specific phosphorothioate ASODN and missense oligonucleotide (MSODN) target Livin mRNA were synthesized and transfected into K562 cells following cationic liposome. The proliferation inhibition of K562 cells was assessed by MTT. The apoptosis rate of each group was detected by Annexin V-FITC. The expression of Livin mRNA was detected by reverse transcription polymerase chain reaction (RT-PCR). Results ASODN at a final concentration of 600 nmol/Lcould inhibit the K562 cells proliferation (IR) was (52.99t2.67) % and the expressions of Livin mRNA (ODR)was (59.75±3.24) %, the apoptosis rate was apparently increased [(36.89±1.08) %] (P ＜0.01); but the difference between Lip-MSODN group, Lip control group and cell control group was not statistically significant (P ＞0.05).Conclusion Livin ASODN may decrease Livin gene expression, suppress K562 cells proliferation effectively, and induce significant apoptosis of K562 cells.

AIM: To study the effects of intrathymic inoculation of liver specific antigen (LSA) on hepatocyte apoptosis after liver allotransplantation. METHODS: Orthotopic liver transplantation was used in this study. Group Ⅰ: syngenic control (Wistar-to-Wistar); Group Ⅱ: acute rejection (SD-to-Wistar); Group Ⅲ: thymus inoculation of SD rat LSA day 7 before transplantation. The observation of general situation and survival time, hepatocyte apoptosis and LAT expression in liver transplants were used to analyze immune state of animals in different groups. RESULTS: The general situation of group Ⅰ was very well after transplantation. Recipients of groupⅡ lost body weight progressively and all died within day 9 to day 13 post transplantation. As for group Ⅲ, the general situation of recipients was remarkably better than that in group Ⅱ. The positive cells of apoptosis in group Ⅲ detected by TUNEL were not significantly different from that in group Ⅰ, but was significantly lower than that in group Ⅱ. LAT was detected at any time in group Ⅱ with peak expression at day 5 and day 7 post transplantation. In contrast, LAT was not detected in any other groups. CONCLUSION: Intrathymic inoculation of LSA protects hepatocytes from apoptosis after liver allotransplantation.

Objective:To study whether sacral lymph nodes should be included in the target volume delineation for those patients with early (stageⅠB-ⅡA) uterus cervix cancer during postoperative radiotherapy. Methods:Forty-six patients with early uterus cervix cancer were given postoperative three dimensional conformal radiation therapy (3D-CRT) in our department for one month after radical resection. The patients were randomly divided into two groups. The sacral lymph nodes were not included in the target volume delineation in the treatment group. But they were delineated in control group. All the patents had no radiotherapy-related contraindications and signed the consent agreement. The patients were followed up. The local controlling rate and the incidence and degree of radioactive proctitis were compared between the two groups. Results:The local controlling rate of the two groups had no significant difference(t=0.000, P=1.000). The doses received by the 5% and 95% volume of the rectum(V_5, V_95), the average dose, and the minimum dose had significant difference between the two groups(t_(V5)=2.169, P_(V5)=0.041; t_(V95)=4.036, P_(V95)=0.001;t_(mean)=2.236, P_(mean)=0.036; t_(min)=2.265, P_(min=0.034), but the maximum dose received by the rectum had no obvious difference (t_(max)=0.518, P_(max)=0.610). The incidence of radioactive proctitis had significant difference between the two groups(t=2.174, P=0.190). Conclusion:For the early uterus cervix cancer patients who have recurrent risk after radical surgery, sacral lymph nodes should not be included in the delineation of target volume during 3D-CRT in order to decrease the incidence of radioactive proctitis.

Objective To explore the diagnosis and treatment efficacy of bronchobiliary fistula due to hepatic cystic echinococcosis.Methods A retrospective evaluation of 39 patients with BBF was performed during 1992 to 2012.We divided the 39 patients into group A treated before 2001 and group B after 2002.A retrospective analysis was made.Results There were three deaths among the 39 BBF patients due to hepatic hydatid disease.The cause of death was septic shock due to severe infection.There were no statistical differences in the basic factors,age (t =0.84,P =0.554),gender (P =1.0),and sputum volume (t =0.98,P =0.703),hydatid diameter (t =1.11,P =0.406),operation time,chest infection (P =1.0),mortality (P =0.235) between the two groups (P ＞ 0.05).While postoperative length of stay(t =7.64,P =0.000),postoperative complications of residual cavity (P =0.001),length of tube drainage(t =6.747,P =0.01),recurrence of bronchial fistula (P =0.022),pleural dissemination (P =0.018),reoperation rate (P =0.049) were all in favour of group B (P ＜ 0.05).Conclusions Surgery is the choice of therapy for BBF due to hepatic hydatid disease,and one-stage procedure is expected to achieve the best outcomes.

Objective To investigate the clinical efficacy and mechanism of vacuum-assisted closure (VAC) in the preoperative and postoperative treatment of bedsore united with skin flap.Methods Twenty two cases with bedsore were randomly divided into experimental and control groups.In the control group,the surgery of flap was performed after the treatment of continuous negative pressure about 7-10 days and the VAC was not applied after operation.While in the experimental group,VAC was not used before operation.It was applied on flaps as soon as sutured the border of flap and decubitus ulcers and removed after 7-10 days.By comparing the general appearance of two groups,microvessel count and the detection rate of bacterial culture and other indicators,the clinical effects of two treatments were investigated and the preliminary mechanism was analyzed.Results After preoperative VAC treatment,11 cases of control group showed a little granulation tissue growth,less subcutaneous hematoma and wound effusion,increased microvessel count and negative bacterial culture.However,there were 4 cases of death cavity residual,subcutaneous hematoma and wound effusion,positive bacterial culture and another 4 cases of delayed healing with skin flap repairing bedsore.The application of VAC in experimental group showed close contact of flap with the basement,less effusion,increased microvessel count and negative bacterial culture.One case of skin flap had a small area of separation,after the dressing of skin and the flap survived.The other wounds healed by first intention.Conclusions The use of VAC to repair bedsore can reduce the number of operation,and it is beneficial to the flap survival.

In order to analyze the immunogenicity of the recombinant EG95s protein ,the recombinant plasmids of pET-1EG95s ,pET-2EG95s and pET-3EG95s which containing respectively 1 ,2 ,and 3 copies EG95s were induced to express HIS-1EG95s ,HIS-2EG95s and HIS-3EG95s ,and then the proteins were purified and identified by western-blotting .The same im-mune process was used ,and 8 weeks-old BALB/c mice were immunized ,then its immunogenicity was analyzed by detecting an-tibody levels in mice by indirect ELISA method .Results showed that for recombinant EG95s proteins after transformation , HIS-1EG95s ,HIS-2EG95s ,and HIS-3EG95s also retained immunogenicity and could induce specific antibodies in mice .One week's late after the first immunization with HIS-1EG95s ,the antibody level of was significantly higher than HIS-2EG95s and HIS-3EG95s .But began from 2 weeks after immunization ,the antibody level of HIS-3EG95s was always higher than that of HIS-1EG95s group during the period of the immune .Both the final antibody titers after immunization of HIS-1EG95s and HIS-2EG95s groups was 1∶819 200 ,while HIS-3EG95s group was 1∶163 840 0 .HIS-1EG95s ,HIS-2EG95s and HIS-3EG95s all induced IFN-γin immune mice ,but the difference was not significant .The HIS-1EG95s showed lower response to Echinococ-cus granulosus positive serum than HIS-2EG95s and HIS-3EG95s .It’s indicated that the HIS-1EG95s and HIS-3EG95s also had good immunogenicity .HIS-3EG95s make recombinant protein immunic effects more lasting ,and benefit to generate more long-lasting protective immunity .This study provides the scientific basis for the immunization of echinococcosis (hydatidosis) .
