ABSTRACT
OBJECTIVE@#To explore the laparoscopic partial gastrectomy and the indications.@*METHODS@#Eighteen patients who underwent laparoscopic partial gastrectomy from August 2005 to May 2006 were analyzed retrospectively.@*RESULTS@#Sixteen patients (including 6 with gastric cancer, 9 with duodenal ulcer, and 1 with gastric multiple polyps) underwent laparoscopic partial gastrectomy. The other two patients underwent an open surgical procedure (1 patient with the tumor size large than 6 cm, and the other patient with bleeding after loosening one clip). The rate of intraoperative subcutaneous emphysema was 5.88% (1/17), and no death occurred. The operation time was (285+/-30)min on average, the estimated blood loss was (130+/-50)mL, and the hospitalization was (11+/-4)d. One case of obstruction of distal loop happened after the surgery, and the rate was 6.25% (1/16). The patients were followed up for 1 approximately 9 months postoperatively. Trocar puncture-site metastases occurred in one patient.@*CONCLUSION@#Laparoscopic partial gastrectomy is safe and feasible with skillful laparoscopic technique and with restricted indications, and the surgical outcome may be similar to that of the open surgery.

Background Experimental data have shown tnat polymorpnisms in tne angiotensm-converting en- zyme 2(ACE2)gene are related to echocardiographically determined parameters of left ventricular mass,structure or function in the general population whether ACE2 genotype influences the effect of angi0tensin Ⅱ receptor blocker which improve left ventricular remodeling and function is unknown.Objective To investigate the association be- tween ACE2 gene G9570A polymorphism and the effect of irbesartan on left ventricular structure and function in hy- pertensive patients.Methods Two hundred and five male patients and 190 female patients who were preliminaryly diagnosised with mild and moderate essential hypertension were treated with irbesartan for 48 weeks with initial dose of 150 mg/d and titrated to 300 mg/d to reach the targed BP.Gene polymorphisms of ACE2 G9570A were detected by PCR-RFLP methods.The association between changes in the SBP,DBP,parameters of left ventricular struc- ture and function and genotypes of the ACE2 gene locus were analyzed.Results Irbesartan reducted in blood pres- sure in all patients(P
ABSTRACT
<p><b>OBJECTIVE</b>To study the difference in the expression of VEGF, bFGF and their receptors between young and postmenopausal women with breast cancer.</p><p><b>METHODS</b>The expression of VEGF, FLK-1, bFGF and FLG in 40 young and 30 postmenopausal women with breast cancer was studied by immunohistochemical method (SABC), with its relation with axillary lymph node metastasis and the clinical and pathologic characteristics. The expression index between these two groups was compared.</p><p><b>RESULTS</b>The positive axillary lymph node rate and the mean expression of VEGF, bFGF in the young group were higher than postmenopausal group (P < 0.01 and P < 0.05), respectively. The mean expression of VEGF, bFGF, FLK-1 and FLG of axillary lymph node positive patients was higher than the negative ones both in young and postmenopausal women groups (P < 0.05 and P < 0.01). There was also a significant difference in VEGF, bFGF, FLK-1, FLG and MVC between the stage 0 - II and stage III - IV (P < 0.05 and P < 0.01) in both groups.</p><p><b>CONCLUSION</b>Breast cancer angiogenesis, characterized by the high expression of VEGF and bFGF, is directly correlated with the high tumor aggressiveness in the young women.</p>
