Post-operative recurrence and metastasis remain the leading causes of death for patients with gastric cancer. The major determinants of recurrence and metastasis are the biological characteristics of cancer cells and the immunological status of the patients. In recent years, due to the target-specificity, biotherapy has yielded efficacious responses in diverse clinical applications for cancer treatment, partially for the treatment of recurrence and metastasis of gastric cancer. However, because of the high diversities in clinical manifestations, patients' condition, and tumor's characteristics, there is no ideal strategy of biotherapy established for the prevention and treatment of recurrence and metastasis in gastric cancer. Therefore, a lot of work need to be done in basic research and clinical trial to make the biotherapy effective in treatment of gastric cancer recurrence.

OBJECTIVESTo research radiographic anatomy of the main structure of the pelvic Teepee view, including its azimuth direction and view anatomy structure.

METHODSFrom June 2013 to June 2014 adult pelvic CT examination results were filtered, excluding skeletal deformities and pelvic osseous destruction caused by tumors, trauma, etc. The data of 2.0 mm contiguous CT scan of 9 adults' intact pelves was,selected and input into Mimics 10.01 involving 7 males and 2 females with an average age of (41.2±10.3) years old. Utilizing the software, the 3D CT reconstructions of the pelves were completed. Setting the transparency being high,the pelvic 3D reconstructions were manipulated from the pelvic anteroposterior view to the combined obturator oblique outlet view and fine-tuned till the regular Teepee-or teardrop-shaped appearance emerges. Cutting tools of the software were at the moment applied to separate the "Teepee" from the main pelvis for each reconstruction. Then the "Teepee" and the rest (main) part of the pelvis were displayed in different color to facilitate the analysis on the Teepee, iliac-oblique, and anteroposterior views.

RESULTSThe "Teepee" started from the posterolateral aspect of the anterior inferior iliac spine and finished at the cortex between the posterior superior iliac spine and the posterior inferior iliac spine in a direction of being from caudal-anterior-lateral to cranial-posterior-medial. The radiographic anatomical composition of the "Teepee" contained one tip, one base,and two aspects. With the inner and outer iliac tables being the inner and outer aspects of the "Teepee", the tip is consequently formed by their intersection. The base is imaged from the cortex of the greater sciatic notch. The medial-inferior-posterior portion of the "Teepee" contains a small part of sacroiliac joint and its corresponding side of bone of the sacrum.

CONCLUSIONSThe "Teepee" is a zone of ample osseous structures of the pelvis, aside from a small medial-inferior-posterior portion, the main zone of which can be accepted as a safe osseous zone for the anchor of implants stabilizing certain pelvic and acetabular fracture patterns. The Teepee view can be utilized as guidance for the safe percutaneous insertion of such implants.

The stability of melittin in different solvents (water, deoxygenated water, physiological saline, PBS, 50% ethanol, ethanol, glycerol)was studied and the results showed that the stability of melittin is not influenced by light, temperature and pH in 50% ethanol, which melittin can be completed dissolved when compared with ethanol and glycerol, in such, 50% ethanol was chosen as solvent storage when measured content of melittin. Then the effect of different concentrations of PBS, the pH of PBS and rat skin ho- mogenates were tested, and the results showed that melittin was degraded rapidly at low concentration solution and low ionic strength. Increasing pH of PBS and rat skin homogenate can accelerate the degradation of melittin. These researches provide an experimental ba- sis for further study of melittin.

OBJECTIVETo analyze the influence of included angle between the anterior aspects of S2 and S vertebral bodies on pelvic inlet imaging in the pelvic midline sagittal plane.

METHODSTotally 58 axial pelvic CT scans were chosen as study objects including 43 males and 15 females,with an average age of 40.7 years old (ranged,18 to 68 years old). The angles between the anterior aspects of S2 and S1, vertebral bodies and the horizontal plane on midline sagittal CT reconstruction were measured to simulate the optimal S2 and S1 inlet angles. The included angle between the anterior aspects of S2 and S1 vertebral bodies was calculated by subtrocting the S1,inlet angle from the S2 inlet angle defined as a base number. Then, the impact of the calculated included angles on the pelvic inlet imaging was analyzed. Results:The S2 inlet angles averaged (30.5±6.5) degrees; the S inlet angles averaged (25.7±5.9) degrees. The difference between them was significant (t=3.35, P=0.001). Ten patients had zero angle between the anterior aspects of S2 and S1 vertebral bodies; 14 patients had negative angle, averaged-(8.9±8.1) degrees; 34 patients had positive angle,averaged (11.8+6.4) degrees.

CONCLUSIONThe difference of included angle between the anterior aspects of S2 and S1 vertebral bodies leads to the difference between S1 inlet view and S2 inlet view in most cases, complicating the pelvic inlet imaging,and affecting the reliability of the application of pelvic inlet view. Utilizing the angles measured on the preoperative midlihe sagittal CT reconstruction to obatin the patient-customized S1 and S2 inlet views could accurately guide the S1 and S2 iliosacral screw insertion.

OBJECTIVETo study the association between two single nucleotide polymorphisms (rs4810485 and rs1535045 in CD40 gene) and Kawasaki disease (KD) in Han Chinese children.

METHODSA case-control study was performed on 184 children with KD and 206 normal controls. The polymorphisms of two SNPs in CD40 gene were detected using PCR-RFLP.

RESULTSThere were no significant differences in the genotype distribution and allele frequency of SNP rs4810485 in CD40 gene between the KD and normal groups (P>0.05). The genotype distribution of SNP rs1535045 in CD40 gene in the KD group was significantly different from the control group (P<0.05). T allele of SNP rs1535045 was shown as a risk factor for development of KD (OR=1.592, 95%CI: 1.182-2.144, P=0.004). There were no association between the polymorphisms of the two SNPs and coronary artery lesions (P>0.05).

CONCLUSIONSSNP rs1535045 may be associated with the development of KD in Han Chinese children, while SNP rs4810485 may not.

OBJECTIVETo explore toxicokinetics of tetramethylene disulphotetramine (TETS) in rabbit and the effects on toxicokinetics of TETS after activated charcoal by gavage.

METHODSEight rabbits were exposed through gavage and vein respectively, the blood samples were collected from the center artery in ear of rabbit at an arranged time. Four rabbits were exposed after being intubated into urethra and common bile duct. The samples of bile and urine were collected at arranged times. After being exposed by gavage, activated charcoal (1 g/kg) was administrated in the activated charcoal group and the distilled water (1 g/kg) administrated to the controls. The samples of blood were collected from the center artery in ear of rabbit at arranged times. The contents of TETS in samples were determined by GC/NPD method. Analysed by the 3p87 soft, toxicokinetics parameters of TETS were acquired.

RESULTSTETS was eliminated very slowly in rabbit. The plasma half time in elimination phase (Tke1/2) of TETS was 56.9 hours in vein exposure group and 262.5 hours in oral exposure group respectively. The plasma clearance (CL) of it was only 15.4 ml.kg(-1).h(-1) in oral exposure group and 24.1 ml.kg(-1).h(-1) in vein exposure group. TETS was eliminated from urine in rabbit. The eliminated amount of it from urine was more 5 times than from bile. All parameters of toxicokinetics of TETS were significantly different between the activated charcoal group and the control. Compared to the control, Tke1/2 of TETS in the activated charcoal group was equal to 55%, CL was increased over 3-fold, area under the curve was equal to 30%.

CONCLUSIONTETS was a poison eliminated very slowly in body. The eliminated amount of it from urine was more than from bile. The excretion of TETS could be quickened after activated charcoal by gavage.
