OBJECTIVETo examine the benefits of anterolateral thigh myocutaneous flaps in reconstruction of oral and maxillofacial defects.
METHODSPatients were recruited from February 2002 to June 2013 in the Department of Oral and Maxillofacial Surgery of Central South University. All patients (1,185 patients, 1,212 transferred flaps) underwent reconstructive surgery employing anterolateral thigh myocutaneous flaps. Basic information for all patients including defect side, flap size and type, recipient vessel processing method, donor complications, and postoperative quality of life were recorded and statistically analyzed.
RESULTSAmong the 1 212 transferred flaps, 1 176 survived and 36 showed necrosis, for a survival rate of about 97.0%. No cases presented with local serious complications, and 90% of patients achieved good functional recovery and aesthetically acceptable results after reconstruction of oral and maxillofacial defects at various locations using anterolateral thigh myocutaneous flaps. The time for anastomosis of one vein was significantly less than that for two veins (P=-0.000 3), which indicated one vein anastomosis could significantly reduce the operating time. The incidence of venous crisis, the survival rate after treatment, and the rate of venous crisis resulting in flap necrosis were comparable between the groups (P>0.05).
CONCLUSIONAnterolateral thigh myocutaneous flaps can be easily obtained and provide a good amount of muscle for filling dead space and fascia lata. These flaps can meet the various requirements of oral and maxillofacial defects. Therefore, the anterolateral thigh myocutaneous free flaps are more suitable for oral and maxillofacial defects than other flaps.

ONYX-015 and H101 are E1B 55-kDa protein-deficient replicating C group adenoviruses that are currently in clinical trials as antitumor agents. However, their application in cancer gene therapy is limited by the native tropism of C group adenoviruses. This is in part due to low expression of the C group adenovirus receptor (coxsackievirus-adenovirus receptor, CAR) on malignant tumors. An H101-based chimeric virus vector containing sequences encoding the Ad35 fiber domain instead of the Ad5 fiber (H101-F35) was constructed. This modification allowed infection of tumor cells through CD46, a membrane protein over-expressed on tumors. The CAR and CD46 RNA expression was evaluated by RT-PCR method. H101-F35 conferred a stronger cytocidal effect than H101 and ONYX-015 in tumor cell lines that lacked CAR expression (MDA-MB-435 and MCF-7), while the cytocidal effect of H101-35, H101 and ONYX-015 was similar in high-level CAR expressing cancer cell lines (A549, NCI-H446, Hep3B, LNCaP, ZR-75-30 and Bcap-37). In an MDA-MB-435 xenograft mouse tumor model, tumor growth in mice receiving H101-F35 was significantly inhibited compared with mice injected with H101. These results suggest that the chimeric oncolytic adenovirus H101-F35 vector might be a useful candidate for gene therapy of cancer.

OBJECTIVESTo investigate CD3+CD56+ lymphocytes and their subsets in the peripheral blood of chronic hepatitis B patients and to explore the relationship between these cells and the pathogenesis of their diseases.
METHODSBlood samples from 53 chronic hepatitis B patients, 17 from HBV asymptomatic carriers (ASC) and 19 from healthy controls (HC) were collected. CD3+CD56+ lymphocytes were detected by flow cytometry (FCM), then the CD3+CD56+ lymphocytes were gathered to analyze their expressions of CD4, CD8, TCR Valpha24, TCRalpha/beta and TCRgamma/delta.
RESULTSThe number of CD3+CD56+ lymphocytes of chronic hepatitis B patients (7.4+/-4.6%) was more than those of ASC (4.5%+/-3.5%) and healthy controls (4.4%+/-3.7%). The expressions of TCR Valpha24 on CD3+CD56+ lymphocytes showed no significant differences among the three groups, but the expression of TCR Valpha24 on CD3-CD56+ lymphocytes of ASC ( 2.8%+/-1.4% ) was much more than that of the HC (1.7%+/-1.0%). For the subsets analysis, the CD8 and TCRalpha/beta subsets of CD3+CD56+ lymphocytes of chronic hepatitis B (61.9%+/-16.8% and 68.1%+/-16.9%) were significantly higher than those of the HC (49.2%+/-15.6% and 56.4%+/-17.9%), while the TCRgamma/delta subsets of chronic hepatitis B and ASC (29.6%+/-15.4% and 30.5%+/-14.8%) were decreased significantly than those of the HC (41.4%+/-19.4%). On the other hand, the CD8 and TCRalpha/beta subsets of CD3+CD56+ lymphocytes of severe chronic hepatitis B (69.0%+/-14.0% and 76.1%+/-12.9%) and CD8 subsets of moderate chronic hepatitis B patients (66.4%+/-14.9%) were significantly higher than those of the mild chronic hepatitis B patients (51.4%+/-16.2% and 62.1%+/-14.6%).
CONCLUSIONThe pathogenesis of chronic hepatitis B may positively relate to the high expression of CD8 on the CD3+CD56+ lymphocytes.

This study is to observe the effect of N-(3-phenylallylidene)-6-fluoro-1, 8-(2, 1-propoxy)-7-(4-methylpiperazin-1-yl)-quinolin-4(1H)-one-3-carbonyl hyarazine (FQ16) on apoptosis of hepatocarcinoma SMMC-7721 cells in vitro. With different concentrations of FQ16 at different times used to treat SMMC-7721 cells in vitro, the proliferation of the cells and the inhibition effect of FQ16 on the cell proliferation were examined by MTT assay. Cell apoptosis was determined by Hoechst 33258/PI fluorescence staining, TUNEL and agarose gel electrophoresis method. The effect of FQ16 on topoisomerase II activity was measured by agarose gel electrophoresis using Plasmid pBR322 DNA as the substrate. Mitochondrial membrane potential (MMP, delta psi m) was measured by high content screening image system. The reverse transcriptase-polymerase chain reaction (RT-PCR) was used to detect the expression changes of Bcl-2 mRNA and Bax mRNA. The caspase-9, caspase-8, caspase-3, p53, Bcl-2 and Bax protein expressions were detected by Western blotting analysis. The results showed that the cell proliferation was inhibited by FQ16 at 0.625 - 10 micromol L(-1) in a time-dose dependent manner. Treatment of SMMC-7721 cells with different concentrations of FQ16 for 24 h increased the percentage of the apoptosis cells obviously (P<0.05), the typical ladder DNA in apoptotic cells and a concomitant dissipation of the mitochondrial membrane potential. Compared with control group, FQ16 influenced obviously DNA topoisomerase II activity, stimulated DNA cleavage and inhibited DNA reunion mediated by topoisomerase II. In addition, FQ16 (3 - 7.39 micromol L(-1)) increased mRNA expression of Bax and protein expression of p53, Bax, caspase-9, caspase-3, separately, and induced cytosolic accumulation of activities caspase-9 and caspase-3, whereas the mRNA and protein expression of Bcl-2 decreased with no change of caspase-8. Therefore it can be concluded that the effects of inhibited topoisomerase II and mitochondrial-dependent pathways were involved in FQ16 induction of apoptosis of SMMC-7721 cells.

OBJECTIVE:
To assess the capacity for logistics, public education, and training in managing public health emergency in China at present.
METHODS:
Four provinces were selected using stratified sampling. All the municipalities of these 4 provinces were assessed using the 9th and 10th subscales (logistics, public education and training) of Preparedness and response capacity questionnaire for public health emergencies for provincial or municipal governments developed by the Center for Health Statistics and Information, Ministry of Health of China.
RESULTS:
Sixty of the 66 questionnaires (90.91%) were collected. Among the 60 investigated municipalities, 80% established a specific agency to take charge of emergency material storage, management and allocation, 65% developed standard for material storage, 35% developed standard of places for material storage, 25% built regulation for testing, maintaining, and updating the emergency materials regularly, 45% arranged budget for routine payment, 27% established standard of emergency fund, and 28% set up the procedure to initiate emergency fund. The average of standard score of subscale 9 was 43.33 (95% confidence interval, 35.65~51.01). 25% of the 60 municipalities conducted assessment for training in the past 2 years, 53% developed plan for emergency personnel training, 20% developed effectiveness assessment regulation of emergency personnel training, 80% assigned a specific agency to be responsible for public education, and 23% established regulation for public education. The average of standard score of subscale 10 was 47.43 (95% confidence interval, 40.69~54.17).
CONCLUSION
Serious problems are found in logistics, public education, and training for public health emergency management in China. Measures should be taken immediately by the central and local government to improve these capacities.
