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

OBJECTIVETo investigate clinical effects of arthroscopy in the treatment of medial meniscal cyst.

METHODSFrom June 2011 to January 2013, 7 patients with medial meniscal cyst were treated with arthroscopy. There were 3 males and 4 females,ranging in age from 27 to 63 years old,with a mean age of (43.93±2.10) years old. The cysts have been discovered for 3 to 30 months,with a mean time of (10.6±1.3) months. All the patients complained of knee pain,especially in the medial joint gap. The Pisani sign, Caklin sign and medial McMurray sign were all positive. Preoperative MRI examination confirmed the diagnosis. Lysholm score changes and clinical efficacy were observed through a six-month follow-up.

RESULTSThe postoperative Lysholm scores were all significantly higher than the preoperative scores. According to Sarimo standard, 6 patients got an excellent result, and 1 good.

CONCLUSIONArthroscopic treatment of medial meniscal cyst has replaced the traditional method, which could retain the normal meniscus as much as possible and repair the meniscus injury simultaneously, as well as get a good curative effect and a good recovery of knee function. This method is worthy of clinical application.

Objective To investigate the expressions of CXCR4 in Barrett esophagus (BE), esophageal adenocarcinoma (EADC) and esophageal squamous cell carcinoma (ESCC), and its relationship with pathology, clinical staging and lymph node metastasis. Methods The expressions of CXCR4 in 56 cases of normal esophageal mucosa, 80 BE (including 22 BE with multifocal dysplasia), 25 EADC and 48 ESCC were examined with immunohistochemical method. Results CXCR4 was expressed in most samples of BE (80. 8% ), EADC (68. 0% ) and ESCC (78.4%) without significant difference ( P ＞ 0. 05 ), which was significantly higher than that in normal esophageal mucosa (39. 3%, P ＜0. 01 ). The level of CXCR4 expression in BE, EADC or ESCC were not related with gender, age, or location of the foci ( P ＞ 0. 05). There was no significant difference in CXCR4 expression between BE without dysplasia or BE with multifocal dysplasia ( P ＞ 0. 05 ). CXCR4 expression level in well-differentiated EADC was significantly higher than that of mild or poorly differentiated (P ＜ 0. 05 ). CXCR4 expression level was higher in EADC with lymph node metastasis than those without ( P ＜ 0. 05 ). CXCR4 level in ESCC with TNM staging grades Ⅲ -Ⅳ was higher than that of grades Ⅰ - Ⅱ, and this variable was also higher in cases with lymph node metastasis than those without (P ＜ 0. 05), so was the case of well and poorly differentiated ESCC (P ＜ 0. 01 ). Conclusion Increased expression level of CXCR4 may be a common feature of EADC and ESCC, which is irrelevant to pathological types. CXCR4 level rises at the stage of BE, which is associated with the degree of tumor differentiation, lymph node metastasis and TNM staging. CXCR4 expression is of guiding significance in the diagnosis of BE, EADC and ESCC, and is the potential drug target.

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.
