Objective:To analyze the metastasis rule of abdominal lymph node from thoracic esophagus carcinoma. Methods:The abdominal lymph node data on 164 patients who had undergone resection of thoracic esophageal carcinoma were analyzed retro-spectively. Grouping was based on the upper, middle, and lower thoracic esophagus. Differences in tumor infiltration depth, differentiat-ed degree, pathological type, pathological stage, and metastasis rate of the abdominal lymph node among the three groups were com-pared. The metastasis rates of the abdominal lymph nodes among the different tumor infiltration depths, differentiated degrees, and path-ological types were also compared. Results:The base condition of tumor infiltration depth, differentiated degree, pathological type, and pathological stage has no statistical significance among the upper, middle, and lower thoracic esophagus. The metastasis rate of the ab-dominal lymph node also has no statistical significance among the three groups (upper, 6.9%;middle, 27.4%;and lower, 39.6%). More-over, the metastasis rate of the abdominal lymph node has no statistical significance among the different tumor infiltration depths, differ-entiated degrees, and pathological types. Conclusion:A special bound lymph node metastasis was present in the esophageal carcinoma. If the tumor in the upper thoracic esophagus infiltrated the submucosa, then it could bound metastasize down to the abdominal lymph node by the lymphatic capillary net. The majority of the esophageal carcinoma was more than T1b period when diagnosed. The tumor has infiltrated the submucosa. Thus, early stage, well-differentiated, and upper thoracic esophageal carcinoma does not indicate mini-mal metastasis of the abdominal lymph node. Routine abdominal lymph node dissection through radical surgery for esophageal carcino-ma was necessary.

BACKGROUND: There are some reports about the relationship between atherosclerotic cerebral infarction and apolipoprotein E and B, but the results are still controversial. The relationship between apolipoprotein E and B and young adult atherosclerotic cerebral infarction has not been reported yet in China.OBJECTIVE: To investigate the relationship between the polymorphism of apolipoprotein E and B gene and young adults atherosclerotic cerebral infarction (ACI).DESIGN: A controlled case analysis of young adult atherosclerotic cerebral infarction patients.SETTING: Department of Neurology, Shengjing Hospital of Chinese Medical University.PARTICIPANTS: This study was conducted in the Department of Neurology, Shengjing Hospital of Chinese Medical University from January of 1998 to December of 2000. Thirty-six young adult patients with atherosclerotic cerebral infarction, including 30 males and 6 females, with the meaage of (41.6±6.54) years, and 100 healthy young adults, including 66 males and 34 females, with the mea age of (36.16±6.12) years were included in this study.METHODS: 8 Ml venous blood was collected after fasting for 12 hours to assay serum lipid and apolipoprotein. The gene polymorphism of apolipoprotein E and B were detected with PCR method. Enzymic method was used to detect total cholesterol, total triglycerides and high density lipoprotein-cholesterol (HDL-C). Apolipoprotein AI.B was measured with immunoturbidimetry method and lipoprotein (a) with ELISA method.Lipids, lipoprotein and apolipoprotein of six control blood samples couldn't be measured because of hematolysis.MAIN OUTCOME MEASURES: ① The distribution characteristics of genotypic frequency of apolipoprtein E and B in the two groups. ② The relationship between gene polymorphism of aoplipoprotein E and B and the level of blood lipids, lipoprotein and apolipoprotein. ③ The correlation intensity between genotypes of apolipoprotein E and B and onset of young adult atherosclerotic infarction.RESULTS: ① In ACI group, ε3/4 counted for 36.1% and ε2/4 for 27.7%, but was 12% and 7% in control group respectively. The gene frequency of ε4 was 0.320. All these values were higher than that in control group 0.95 (P ＜ 0.05). ② The levels of TG, TC, and LP (a) in ACI group were higher than that in control group. The level of HDL-C was much lower than the control group's (P ＜ 0.05-0.01). ③ ε4 allele caused the increase of the content of TG, TC, and LP (a) so as to induce the relative risk rates of decrease of HDL-C which were 8.23, 4.85, 29.9,4.39 (P ＜ 0.01-0.001) respectively. ④ AI content of the gene frequency of ApoB XbaⅠ X+X- was (1.01±0.30) g/L in ACI group, which was lower than (1.33±0.15) g/L in X-X- subgroup (t=2.55, P ＜ 0.05). The level of ApoA I in X+X group (244.3 mg/L) was remarkably different from that (183.0 mg/L)in control group (t=4.50, P ＜ 0.01). ⑤ Three cases had both ε3 and X+X-in ACI group, 10 had both ε3 and X-X-, 2 had both ε4 and X+X-, and 19 had both ε4 and X-X-. The risk of ACI was 2.85 with the linkage of allele ε4 and allele X-X- in ACI patients (x2=1.52, P ＞ 0.05).CONCLUSION: Allele ε4 is a genetic facilitated factor of young adults ACI. Xba Ⅰ X+X- is another probable genetic symbol. The correlation between atherosclerotic cerebral infarction of young patients during the combination of apolipoprotein E and B should be researched further.

Selective courses are different from compulsory courses in teaching objective,students' study demand,teaching content.Different teaching designs should be used according to different teaching objectives in selective courses for graduates.Targeted scientific thoughts and methodological training should be designed with respect to the fact that students will begin their experimental studies after the selective lessons.We analyzed the current status of selective course of neuroanatomy for graduates and proposed some solutions.

Objective To study the molecular pathway of osteoblastic differentiation induced by substance P (SP), a neurotransmitter. Methods Mesenchymal stem cells were isolated and cultured, and treated with SP or its receptor (NK1) antagonist to induce osteoblastic cell differentiation, respectively. Alkaline phosphatase activity was determined; Osterix gene expression was detected by RT-PCR after 1-2 weeks for three times. The data of each culture condition were analyzed using SPSS12.0 statistical software to determine whether the differences between conditions were significant. Results After 4-5 days' culture, bone marrow stromal cells became spindle-shaped, triangular or polygonic. They covered the plate surface, formed extensive cell sheets in each group after 11-12 days of culture, and then induced differentiation to osteoblast. SP up-regulated the important transcription factor Osterix gene expression significantly (P<0.05). Conclusion The up-regulation of Osterix gene expression by SP may stimulate osteoblastic cell differentiation. SP's regulation depends on its receptor NK1.
