Objective To investigate the relationship between the tumor differentiation and the related pathologic factors in Esophago-gastric junction adenocarcinoma. Methods The pathological data from 163 patients of Esophago-gastric junction adenocarcinoma underwent radical surgical resections were randomly divided two groups (group1: well-differentiated,group2: poor-differentiated). The composition of N stages,T stages,morphological type and vessel carcinoma embolus were compared between the two groups ,respectively. The tumor sizes and the number of metastases lymph nodes were compared between the two groups. Results The cases with lower N stages or T stages in group1 were dominant(T1 and T2:55. 74%,N1 and N2:75.41%). Oppositely,those with higher N stages or T stages were dominant(T3 and T4:59.81%,N1 and N2:57.85%)in group 2. The differences were significant Incidence of vessel carcinoma embolus was 44. 26%(27/61)in group 1 and 63. 73%(65/102)in group 2,with a significant difference. There was no significant difference for morphological type in the two groups. The tumor sizes and the number of metastases lymph was 4. 27 ±2. 00 cm and 4. 15 ±5.27 respectively in group 1 ,and 5. 87 ± 3. 26 cm and 8. 80 ± 7.65 respectively in group 2. The differences were significantly different(Ps ＜ 0. 01).Conclusions The tumor differentiation has significant effect on N stages,T stages,vessel carcinoma embolus,tumor size and the number of metastases lymph nodes in Esophago-gastric junction adenocarcinoma.

Objective To discuss the role of DNA-dependent protein kinase catalytic subunit (DNA-DPKCS) in human lung adenocarcinoma cell line (A549) by using small interfering RNA (siRNA) to specifically knockdown DNA-DPKCS expression and its effects on cell proliferation, cell cycle and radio-sensitivity. Methods The DNA-DPKCS-siRNA expression vector was constructed and transfected into A549 cell line. The transformed clones were randomly selected and isolated. The cell cycle distribution and apop-tesis were analyzed by flowcytometry analysis. Cell survival was detected by using clonogenic formation as-say. Results With specific inhibition of DNA-DPKCS expression, stable transfected cell line 549pRNA-DNA-DPKCS was constructed by RNA interference technique. The 549pRNA-C and 549pSUPER cell lines were the control cell lines tansfected with control and blank plasmids, respectively. Compared with A549 cells, the expression levels of DNA-DPKCS mRNA (0.110: 1. 000), protein (0. 870: 2.967) and activity of DNA-DPKCS (0.004: 0.266) in 549pRNA-DNA-DPKCS cells were significantly lower (F = 80.55 ,P < 0.01;F=63.96, P<0.01;F=51.62,P<0.01, respectively). The analysis of SF_2(0.25:0.76), D_0 (1.42:1.62) and D_q (0.06: 1. 00) showed significant difference between 549pRNA-DNA-DPKCS and A549 cells (F = 996.86, P < 0.01 ; F = 17.41, P < 0.05 ; F = 68.92, P < 0.01). The number of 549pRNA-DNA-DPKCS cells in S (24.5%: 35.5%) and G_2 (10.7%: 11.0%) phases was significantly decreased (F = 4.83, P<0.05 and F=32.04, P <0.01, respectively). Conclusions In A549 cells, inhibit of DNA-DPKCS gene expression can enhance the radiosensitivity and affect cell cycle distribution.

Objective To detect the serum lipids levels in the subjects aged 40 years and over in the Guangxi Bai Ku Yao population. Methods A total of 485 subjects of Bai Ku Yao and 501 Han people aged 40 years and over were surveyed by cluster sampling methods. Informations on demography, diet and lifestyle were collected by standard questionnaires. Blood pressure, height,weight, waist circumference, serum lipids and apolipoproteins (apo) were measured, and body mass index (BMI) was calculated. Results Education level, height, weight, BMI, waist circumference,blood pressure levels, hypertensive prevalence, and the intakes of total energy, total fat, total protein, dietary cholesterol, and salt were higher in Han than in Bai Ku Yao (P<0.05 or P<0.01),whereas physical activity level, and the intakes of carbohydrate, vegetal protein, and total dietary fiber were higher in Bai Ku Yao than in Han (all P<0.001). The serum levels of total cholesterol,high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, apo A1, and apo B were significantly lower in Bai Ku Yao than in Han [(4. 43±0. 90)vs. (4.96±1.04)mmol/L, P<0. 001;(1.73±0. 42) vs. (2.01±0. 49) mmol/L, P<0. 001;(2. 62±0. 75) vs. (2. 72±0. 78)mmol/L, P<0. 05;(1. 36±0. 33) vs. (1. 48±0. 24)g/L, P<0. 001;and (0. 86±0.23) vs. (0. 95±0. 22)g/L,P<0. 001 ;respectively]. There were no significant differences in serum triglyceride level and the ratio of apo Al over apo B between the two ethnic groups (P>0. 05). Conclusions There are significant differences in lipids levels and the risk factors between Bai Ku Yao and Han populations, which might result from different dietary habits, life styles, and physical activities.
