Objective To investigate the effect of Lecarnidipine on hypertension and circulation hematopoietic progenitor cells (HPCs) count in elderly patients.Methods A total of 61 elderly patients with hypertension were selected in Renji Hospital geriatric hypertension clinic from January 2014 to August 2014.Patients were randomly divided into two groups:Lercanidipine treatment group (n=32,Lercanidipine hydrochloride 5-10 mg/day),the control group (n=29,thiazide diuretics and / or beta blockers according to patient's condition).Patients were observed for 12 weeks,and the target blood pressure level was ＜140/90 mmHg (1 mmHg=0.133 kPa).Blood lipids and glucose levels,liver and kidney function and erythrocyte sedimentation rate (ESR) were determined before and after treatment.The quantity of circulation HPCs (the percentage of CD34+ CD45dim in peripheral blood in 100000 mononuclear cells) was detected by flow cytometry analysis.Results Blood pressure in Lercanidipine treatment group was decreased after the treatment (P＜0.01),and patients reached the target blood pressure.There was no difference in the decrease of blood pressure level between the two groups (P＞0.05).The number of CD34+ CD45dim cells was increased after 12 weeks of Lecarnidipine treatment [(0.022 + 0.003)％ vs.(0.034 + 0.028)％,P＜0.05].Compared with the control group,the number of CD34+ CD45dim cells in lercanidipine group had a rising trend,but it had no statistical difference (P＞0.05).Taking the number of CD34+ CD45dim as the independent variables,the multiple stepwise linear regression analysis showed that the number of CD34+ CD45dim cells was negatively correlated to systolic pressure.Conclusions The number of circulation HPCs is negatively correlated with systolic pressure in the elderly.Lercanidipine can increase the number of circulation HPCs,and does not rely on its antihypertensive effect.

Objective To explore the prognostic role of laminin (LN ) as a tumor biological marker in predicting the recurrence of hepatocellular carcinoma (HCC) related with HBV infection after liver transplantation (LT ) .Methods Tissue samples from 251 HBV-related HCC patients undergoing LT were immunohistochemically stained with anti-LN antibody .The relevant prognostic factors were analyzed using Spearman's rank test , Kaplan-Meier method , log-rank test and multivariate step-wise Cox regression analysis .Results The expressions of LN in tumor tissues were significantly positively correlated with tumor number (P=0 .00) ,microsatellite (P=0 .02) ,venous invasion (P=0 .048) ,pTNM tumor stage (P=0 .00) ,pre-LT serum α-fetoprotein (AFP) level (P=0 .00) ,HBV DNA level (P= 0 .02) ,HBeAg level (P= 0 .02) and tumor recurrence (P= 0 .00) respectively .Significant differences existed in 1/3/5-year overall survival or tumor recurrence-free survival rate post-LT among LN different expression (-,+ ,≥ + + ) in HBV-related HCC patients (P< 0 .05 ) . Multivariate analysis indicated that LN was a significantly independent predictor in predicting poor tumor recurrence-free survival post-LT (P=0 .01) .Conclusions LN may be a feasible marker in predicting HCC recurrence post-LT for HBV-related HCC patients .
