Journal of Shanghai Jiaotong University(Medical Science) 2006;0(11):-
Objective To investigate the role of compound traditional Chinese medicine Yiqilin in the regulation of immune-related genes expression in spontaneously hypertensive rats(SHR).Methods Ten SHR were randomly divided into test group(fed with Yiqilin and ordinary food at the ratio of 1:9 for 6 months,n=5)and control group(fed with ordinary food for 6 months,n=5).Total RNA was extracted from myocardial tissues of SHR after 6 months,and gene chip hybridization technique was employed to analyse the expression of immune-regulated genes of myocardial tissues in two groups.The genes with differentiation expression were screened,and were verified by Real-time PCR.Results The expression of 32 immune-related genes were up-regulated in the test group,including interleukin(IL)6 receptor,IL-6 signal transduction factor,chemotatic factor,antigen presenting molecule,antibody receptor,heat shock protein(Hsp), etc.No immune-related gene was down-regulated in test group.The results of 2 immune-related genes(Hsp 105 and Hsp 90)detected by Real-time PCR were consistent with those by gene chip hybridization.Conclusion Part of the immune-related genes in myocardial tissues in SHR may be up-regulated by Yiqiling,which indicates that Yiqiling may play a role in the regulation of expression of immune-related genes in SHR.

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.

Purpose:To assess the effect of surgery combined with intraoperative radiotherapy (IORT) in the treatment of rectal carcinoma.Methods:97 patients with rectal carcinoma underwent IORT with 10~30Gy by 9~16MeV elect ro n beam to the tumor bed and local lymphatic regions. Another 122 patients treate d by surgery alone served as control.Results:Surgery combined w ith IORT did not improve the 5-year survival rate and local recurrence rate in the stage Dukes A patients. IORT have increased the 3-year and the 5-year surv ival rates in the stage Dukes B patients to 19.9%?27.2%, decreased their local recurrence rates to 19%?20.2%(P

Objective To investigate expression of C-MET in palliary thyroid carcinoma(PTC) detected by rapid immunohistochemical analysis and its clinical significance to predicting lymph node metastases.Methods The expression level of C-MET was examined by rapid immunohistochemical analysis with C-MET-EPOS antibody in 85 cases of PTC.Results The rate of cervical lymph node metastates in PTC with strong positive stain expression(95.0%,23/25) was significantly higher than in PTC with positive stain expression(13.4%,8/60)(P

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 determine the clinical value of the multi-slice spiral CT virtual endoscopy (CTVE) for the detection of biliary pancreatic junction lesions. Method MSCT and virtual endoscopic reconstruction were performed in 30 healthy volunteers, 18 cases of common bile duct stones and 7 cases of ampullary carcinoma to observe patterns of duodenal papilla and measure its size.Results Reconstructed image of CTVE showed that the normal duodenal papilla was nodular in 16,shaped like "V" in 8 "Y-shaped" in 6 of the healthy volunteers. Its diameter was (0.84±0.17)cm. In the patients with common bile duct stones, it was nodular and its diameter (1.72±0.32)cm. In the patients with ampullary cancer, it was of irregular protruded type and its diameter (2.30±0.85)cm.There was significant difference among the 3 groups in the overall mean values (P<0.01). Conclusion CTVE is a convenient, non-invasive and precise clinical examination to observe the shape of duodenal papilla and determine its size.

Objective To investigate the clinical features of acute coronary syndrome (ACS) combined with low T3 syndrome and its prognosis.Method Eighty-seven ACS patients with low free triiodothyronine (FT3) level (low FT3 group) and additional 64 ACS patients with normal FT3 level(control group) were selected in parallel; all the patients underwent coronary angiography.The contents of FT3,N-terminal pro-brain natriuretic peptide (NT-proBNP),cardiac troponin I (cTnI) and high sensitivity-C reactive protein (hs-CRP) were recorded,and the related factors were evaluated.The number of stenotic vessels was calculated.Results The contents of NT-proBNP,cTnI and hs-CRP in low FT3 group were elevated significantly compared with those in control group [(1242.14 ± 226.32) ng/L vs.(1126.36 ±195.55) ng/L,(0.92 ± 0.23) ng/L vs.(0.84 ± 0.19) ng/L,(6.46 ± 2.25) mg/L vs.(5.71 ± 1.78) mg/L],and there were significant differences (P < 0.01 or < 0.05).The contents of FT3 were negatively correlated with NT-proBNP,cTnI and hs-CRP in two groups (P < 0.05).There was no significant difference in the number of stenotic vessels between two groups (x2 =4.512,P =0.105).Conclusion In patients with ACS,there is a negative correlation between contents of FT3 and the prognosis,but there is no correlation between contents of FT3 and the number of stenotic vessels.

Objective To investigate the clinical and pathological characteristics,surgical treatment strategy and prognosis of primary malignant neoplasms of the appendix.Methods The clinical data of 74 patients with primary malignant neoplasms of the appendix in our hospital from January 1982 to December 2012 were retrospectively studied.Results Among the 74 cases of primary malignant neoplasms of the appendix,carcinoids were the most common accounting for approximately 70%,adenocarcinoma accounting for 22% and lymphoma accounting for 8%.The prognosis of primary malignant neoplasms of the appendix is rather poor,nainly because of patients' later presentetion.The overall 1,3,5-year survival rate is respectively 95%,74%,60%,the prognosis of carcinoid is good,while that of adenocarcinoma is poor.Conclusions The incidence of primary malignant neoplasms of the appendix is relatively low.It is difficult to diagnose preoperatively,and the diagnosis relies mainly on rapid intraoperative frozen section and postoperative pathology.
