Objective To investigate the dietary pattern in college freshmen students and to analyze the influencing factors on their dietary patterns. Methods A questionnaire survey on situation of dietary pattern and influencing factors was conducted among 1319 freshmen students.Results Four major dietary patterns were noticed and they were: Ⅰ , high consumption in hamburger,fried food, nuts, biscuit, chocolate, cola, coffee, sugars, Ⅱ, high consumption in pork, mutton, beef,poultry meat, animal liver, Ⅲ, high consumption in fresh fruits, eggs, fish and shrimps, kelp laver and sea fish, milk and dairy products, beans and bean products, Ⅳ, high consumption in rice and grain,fresh fruits, fresh vegetables, pork. Risk factors on dietary pattern were presented as follows: ( 1 )boys: having the food pattern Ⅰ and Ⅱ showed a strong positive association with the place where they live (OR= 1.67, 95％CI: 0.87-3.19; OR= 1.51,95％CI: 0.79-2.88), eating place (OR=1.63,95％CI: 1.O3-2.59; OR= 1.83, 95％CI: 1.04-3.23), level of mother' s education (OR=2.52,95％CI: 1.07-5.95; OR=3.38, 95％CI: 1.50-7.63), family income (OR=2.24, 95％CI: 1.30-3.88;OR=3.06, 95％ CI: 1.77-5.29) and the status of passive smoking (OR= 1.80, 95％CI: 0.70-4.59;OR=1.83, 95％CI: 0.75-4.45). Inverse correlations was found on the level of mother's education (OR=0.56,95％CI: 0.17-1.79). The food pattern Ⅳ showed a strong positive association with place of eating(OR= 1.83,95％CI: 1.04-3.23) but having an inverse correlation with the level of mother's education (OR=0.56, 95％CI: 0.17-1.79). (2)girls when compared with boys, the food pattern Ⅰ showed minor association with the places of living and eating; while the food pattern Ⅱ and Ⅲ had minor association with the status of passive smoking. Conclusion Socio-demographic factors and lifestyle had influenced on the dietary patterns among college freshmen students who should be guided to have a reasonable, balanced diet in the college.

Objective To understand the genetic polymorphism of Salmonella and Staphylococcus aureus in Guangdong province, as well as to explore methods for identifying and tracing the source of these two foodbome pathogens. Methods Using the automated ribotyping system, two foodbome pathogens were tested with either EcoR Ⅰ or Pvu Ⅱ restriction enzymes. BioNumerics software was then applied for image analysis, database establishment and other corresponding analysis. Results Digestion of 32 Salmonella isolates with Pvu Ⅱ yielded 19 different ribotypes,and digestion of 14 Salmonella isolates with EcoR Ⅰ yielded 2 different ribotypes. Staphyloccus aureus isolates showed greater genetic diversity, whereas EcoR Ⅰ digestion of 49 different isolates yielded 31 different ribotypes. Conclusion Unique Salmonella and Staphylococcus aureus isolates could be identified through ribotyping. Although Salmonella serotyping and ribotyping were not strongly correlated, the combination of both restriction enzymes could be used to more effectively identify the genetic relationship among different strains as well as the source of food poisoning. Thus, not only could the genetic relationships amongst the different strains be inferred through ribotyping skills, the source of food poisoning and mode of transmission could also be determined under the use of this method.

OBJECTIVETo investigate the tumor suppression efficacy of histone deacetylase inhibitor, phenylbutyrate (PB), in combination with DNA methylation inhibitor 5-Aza-2-deoxycytidine (5-Aza-CdR) in the treatment of Kasumi-1 xenograft tumor in nude mice and its mechanism.

METHODSThe nude mice model of Kasumi-1 xenograft tumor was established by subcutaneous inoculation. Latency of tumor formation, the ability of Kasumi-1 cells pre treated with PB to form the xenograft tumor, and the tumor suppression activity of PB and 5-Aza-CdR by intraperitoneal injection in xenografted mice model were detected. Cell differentiation and cell cycle parameters of the tumor cells were analyzed by flow cytometry analysis, apoptosis by TUNEL in situ hybridization, and tumor microvessel density (MVD) by immunohistochemistry study.

RESULTSThe latency of tumor formation in mice with or without previous lienectomy was 17 approximately 23 and 40 approximately 50 days, respectively. Tumor cells xenografted could not be found in other tissues than in inoculation area, and still harbored the specific t(8;21) and AML1-ETO fusion gene. When the xenografted mice models treated with PB, 5-Aza-CdR, or both, the tumor growth inhibition rates were 49.07%, 25.69% and 87.46% (P < 0.05), the apoptosis indexes (AI) of tumor cells were (2.25 +/- 0.85)%, (1.32 +/- 0.68)%, and (5.41 +/- 1.56)% (P < 0.05), and the microvessel densities (MVD) were 21.69 +/- 6.25, 28.34 +/- 4.24 and 9.48 +/- 3.21 (P < 0.01), respectively. All the data above were significantly different from that in control (P < 0.05). The expression of CD11b and CD13 antigen of the tumor cells was increased in xenografted mice model treated with PB when compared with the control \[(12.08 +/- 1.02)% and (54.91 +/- 2.72)%\], respectively (P < 0.01), and tumor cells showed a cell cycle arrest with increased G(0)/G(1)-phase cells and decreased S-phase cells.

CONCLUSIONPB inhibited the growth of Kasumi-1 xenograft tumor by inducing tumor cell apoptosis and differentiation, and suppressing its angiogenesis in vivo. 5-Aza-CdR could significantly enhance the antitumor activity of PB.

OBJECTIVETo investigate the value of application of mandibular outer cortex as bone graft by comparing its bone absorption with cranial outer cortex.

METHODS8 minitype grown-up pigs at the age of 8 - 12 months underwent surgery of taking out the same size (2.5 cm x 1.0 cm) of outer cortex from mandible and craninium. The volume of the outer cortex was measured by volume-displacement method. Then the outer cortex of mandible and cranium were onlay grafted to the each side of the pig snout, respectively. 12 weeks later, 2 pigs were randomly selected for histological examination. The other 6 pigs were killed 24 weeks after surgery for measurement of the bone graft volume and histologic examination.

RESULTSThe bone graft absorption rate was (41 +/- 5)% for mandibular outer cortex and (46 +/- 12)% for cranial outer cortex, showing no significant difference between them (P = 0.51). The histologic examination results also had no marked difference in the bony healing and reforming between the two graft.

CONCLUSIONSMandibular outer cortex is a good donor site for onlay bone graft in craniofacial region.
