Objective To investigate the relationship of the expressions of transforming growth factor ?_1(TGF?_1),vascular endothelial growth factor(VEGF) with angiogenesis in thyroid cancer.Method TGF?_1,VEGF and microvessel countt(MVC) were detected by immunohistochemical method in 46 thyroid cancer specimens.Results The mean MVC was significantly higher in tumors with positive TGF?_1 or VEGF than in tumors with negtive TGF?_1 or VEGF[(26.18?4.05) vs (20.13?4.29) for TGF?_1 and (25.82?3.61) vs (19.65?6.32) for VEGF,P

Objective To compare the advantages and disadvantages of retroperitoneal laparoscopic sur -gery and open surgery in treatment of adrenal adenoma , in order to provide the clinical evidence for the selection of surgical treatment of adrenal adenoma .Methods 120 cases undergoing surgical treatment from Jan .2005 to Dec.2010 were randomly divided into laparoscopic group and open surgery group .Operation indicators , postop-erative recovery indicators , postoperative clinical manifestations , success of operation , complications and follow-up data were evaluated and compared between the 2 groups.Results 3 cases in laparoscopic group and 4 cases in open surgery group withdrew.The operation time, intraoperative blood loss, and blood transfusion cases were (89.6 ±18.4)min vs (124.2 ±27.3)min, (70.2 ±17.2)ml vs (205.7 ±51.9)ml, and 8 cases vs 20 cases in laparo-scopic group and open surgery group .Extubation time, starting feeding time, time of getting out of bed, and length of hospital stay were (2.8 ±1.3)d vs (4.2 ±2.0)d, (1.7 ±1.1)d vs (2.9 ±1.4)d, (2.6 ±1.2)d vs (5.1 ± 3.1)d and (6.2 ±3.1)d vs (13.5 ±5.4)d in laparoscopic group and open surgery group .Postoperative analge-sic using cases and drainage volume were 11 cases vs 43 cases, and(15.4 ±4.2)ml vs(45.1 ±12.7)ml in lapa-roscopic group and open surgery group .The difference had statistical significance (P＜0.01).The cost was simi-lar between the 2 groups(P>0.05).The open surgery group had no death or relapse within 1 year, while 5 cases in laparoscopic group converted to laparotomy , with 1 case of death and 2 cases of relapse within 1 year.The complications incidence was 3.51%(2/57)in laparoscopic group, obviously lower than 16.07%(9/56)in open surgery group(P＜0.01).Conclusions Compared to the traditional open surgery, retroperitoneal laparoscopic sur-gery has advantages of less trauma, fewer complications, and faster postoperative recovery in treatment of adrenal ade-noma.Experience and skills of surgeon need to be improved to reduce the possibility of failure or recurrence .

Objectives:To explore the influencing factors of inter-arm systolic blood pressure difference(sIAD)in young hypertensive population. Methods:A total of 12 895 young Kailuan employees aged≤40 years,who participated in the physical examination from 2010 to 2020,were enrolled in this study.All of them underwent blood pressure measurements of four limbs in supine position.Young hypertensive group(n=3 584)and young non-hypertensive group(n=3 584)were 1∶1 matched by sex and age(±1 year),and participants were further divided into sIAD＜10 mmHg(1 mmHg=0.133 kPa)and sIAD≥10 mmHg subgroups.A stepwise multivariate logistic regression model was established to analyze the determinants of sIAD≥10 mmHg. Results:The detection rate of sIAD≥10 mmHg was significantly higher in the young hypertensive group than in the young non-hypertensive group(31.72%vs.27.76%,P＜0.001).Stepwise multivariate logistic regression analysis showed that in young hypertensive population,ankle-brachial index(ABI)＜0.9,male,obesity,overweight,elevated low density lipoprotein cholesterol(LDL-C)level,and systolic blood pressure were positively associated with sIAD≥10 mmHg,while college education or above,physical exercise were negatively correlated with sIAD≥10 mmHg(all P＜0.05).In the young non-hypertensive population,ABI＜0.9,systolic blood pressure were positively correlated with sIAD≥10 mmHg,while age was negatively associated with sIAD≥10 mmHg(all P＜0.05). Conclusions:The detection rate of sIAD≥10 mmHg is higher in young hypertensive population than in young non-hypertensive population.Decreased ABI,male sex,obesity,overweight,increased LDL-C level,systolic blood pressure,college education and above,and physical exercise are the influencing factors of sIAD≥10 mmHg in young hypertensive population.
