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.

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

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.

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 summarize surgical results of secondary tunnel-like subaortic stenosis( STSS) after congenital heart disease( CHD) operations, analyze the pathogenesis of STSS, evaluate the operative effect and prognosis.Methods We analyzed clinical data of 25 patients who underwent surgical repair for STSS in Fuwai Hospital from January 2009 to December 2015.There were 17 males and 8 females.CHD types included double outlet right ventricle, ventricular septal defect and par-tial atrioventricular septal defect, et al.The median age of the patients when they received their first CHD operations was 1 year (1 month to 42 years).The median age of the patients when they received TSS repair was 5 years and 8 months(2 years and 10 months to 48 years) .The surgical types contained modified Konno procedure , Konno procedure, resection of the conal sep-tum, resection of fibromuscular ridge and myectomy, removal and reconstruction of the intraventricular baffle.Results All the patients successfully received their TSS repair .There was no surgical death in this study .The preoperative gradient of aortic valve pressure was 81(43 to 159)mmHg(1 mmHg=0.133 kPa), and the postoperative gradient was 8.2(4.0 to 46.2) mm-Hg.Ⅲ degree atrioventricular block was occurred in 2 patients after operation and both 2 patients needed to set permanent pacemaker.All the patients were followed up after discharge for a median duration of 2 years( 4 months to 6 years) .During follow-up, none of the patients had any clinical symptom or subaortic restenosis , and there was no late death .Conclusion The pathogenesis of STSS is perhaps related to turbulent flow and shear stress to the left ventricular outflow tract , resulting in the proliferation of fibromuscular marterials and stenosis in the left ventricular outflow tract .The modified Konno procedure and resection of the conal septum are safe and effective.

Objective To the value of ultrasonic imaging in diagnosis of appendiceal mucinous neoplasms in patients.Methods A retrospective review was performed for the 26 cases undergoing pre-operative ultrasonography and finally diagnosed as appendiceal mucinous neoplasms by pathology.The 26 patients were included in the study,11 elderly patients aged ≥60 years as group A,and 15 younger patients aged ＜ 60 years as group B.The characteristics of the ultrasonic imaging were analyzed.Results Features of ultrasound images leading to diagnosis were summarized as following.The lesion transverse diameter was over 2 cm,with anechoic or hypoechoic area of lesion or onion skin sign inside the lesions.There were distinct borderlines between lesions and surrounding tissues,with no or little blood in the color doppler flow imaging.Conclusions There are same u1trasonography characteristics of appendiceal mucinous neoplasms in two age groups.Improving the knowledge of this disease and grasping the clinical and sonography characteristics are stringent to enhance the accuracy rate of diagnosis.

Objective To evaluate the feasibility of interventional catheterization via saphenous artery route in treating hepatic and renal lesions, to compare its advantages and disadvantages with trans-femoral approach catheterization, and to discuss the feasibility of using saphenous artery route to replace femoral artery approach.Methods A total of 24 rabbits bearing VX2 liver and kidney tumor were randomly divided into via femoral artery catheterization group (control group,n=8) and via saphenous artery catheterization group (study group,n=16). Surface distribution and variation of saphenous artery were recorded. After the saphenous artery was isolated, blood vessel was punctured with a 22 G needle, through which a 0.018 inch micro guide wire together with a 5-F micro catheter sheath was inserted into the artery, then, a Y-valve was connected to the sheath. DSA was performed to determine the diameters of the saphenous artery, femoral artery and iliac artery. The used time for isolating the artery and indwelling the sheath, the depth of sheath insertion, the success rate of catheterization, the incision infection rate and the occurrence of claudication in both groups were recorded, and the results were compared. Results Saphenous artery could be clearly observed on body surface in 91.67%of rabbits (22/24). Successful insertion of catheter sheath was achieved in all rabbits of both groups. The used time of isolating artery, the depth of sheath insertion, the incision infection rate and the occurrence of claudication at 7 and 14 days after the treatment in the study group were(367.30±37.30) seconds, (20.20±2.60) mm, 0%, 6.25%and 0%respectively, while those in the control group were (978.20±156.30) seconds,(58.60±9.50) mm, 37.50%, 62.50% and 25% respectively. The differences in above mentioned measurement items between the two groups were statistically significant (P<0.05). The used time of indwelling the sheath and the occurrence of claudication at one day after the treatment in the study group and in the control group were (42.80 ±9.90) seconds, 70% and (43.60 ±7.0) seconds, 100%respectively, and no statistically significant differences existed between the two groups (P>0.05). The diameters of the saphenous artery, superficial femoral artery, common femoral artery, external iliac artery and common iliac artery were (1.29±0.12) mm,(1.91±0.27) mm, (2.18±0.15) mm, (2.22±0.13) mm and(2.39± 0.15) mm respectively. Conclusion In rabbits, the saphenous artery is usually superficially located, its anatomical variation rate is very low, and its internal diameter can match 5- F micro catheter sheath. Catheterization via saphenous artery is convenient, time-saving with less damage and fewer complications. Therefore, in treating hepatic and renal lesions in rabbits the catheterization via saphenous artery can be used as the technique of first choice to replace the femoral approach catheterization.
