OBJECTIVETo investigate whether bortezomib can enhance the sensitivity of human prostate cancer (PCa) cells to natural killer (NK) cell-mediated cytotoxicity, and whether it produces the same effect on different PCa cell lines.
METHODSWe treated androgen-dependent PCa LNCaP cells and androgen-independent PCa DU145 cells with bortezomib at the concentrations of 0, 5, 10, 15, 20 and 25 nmol/L for 24, 48 and 72 hours, and then detected the proliferation and apoptosis of the tumor cells by CCK-8 and Annexin V/PI, respectively.
RESULTSThe proliferation rates of the DU145 cells treated with 15, 20 and 25 nmol/L bortezomib were (82.79 +/-2.04)%, (73.59+/- 2.95)% and (74.16+/- 6. 16)% at 48 hours and (71.24+/- 5.30)%, (51.20+/- 2.91)% and (38.02+/- 2.67)% at 72 hours, and those of the LNCaP cells were (77.04+/- 7.74)% , (42.61 +/- 6.62)% and (23.85 +/-6.04)% at 48 hours and (36.45 +/-7.02)%, (14.94 +/-5.76)% and (11.65 +/-5. 87)% at 72 hours, both significantly inhibited as compared with the control group (P <0.05). At 24 hours, the apoptosis rates of the DU145 cells treated with 15, 20 and 25 nmol/L bortezomib were (14.41 +/- 1.32)% , (16.13 +/- 1.55)% and (14.48 +/- 1.42)% , and those of the LNCaP cells treated with 20 and 25 nmol/L bortezomib were (12.77 +/- 1.28)% and (14. 84 +/- 1.65)% , significantly higher than those of the control group (P <0.05) , and the DU145 cells showed an even higher sensitivity to bortezomib than the LNCaP cells. Bortezomib failed to sensitize these two cell lines to NK cell-mediated cytotoxicity in short-term assay, while long-term assay manifested that the apoptosis rates of DU145 and LNCaP cells after treated with 20 nmol/L bortezomib + NK cells were (41.83 +/- 5.06)% and (30.31 +/- 3.62)% , respectively, significantly higher
CONCLUSIONBortezomib enhances the sensitivity of than those after treated with either bortezomib or NK cells alone (P <0.05). PCa cells to NK cell-mediated cytotoxicity and adds to the effect of current cancer therapies, and it is more efficacious for androgen-independent prostate cancer.

5.Correlation between Ambulatory Arterial Stiffness Index and Renal Abnormalities in Primary Hypertension
Chinese Journal of Rehabilitation Theory and Practice 2009;15(5):479-480
Objective To investigate the relationship between ambulatory arterial stiffness index (AASI) derived from blood pressure monitoring and early signs of renal damage in patients with primary hypertension. Methods 74 primary hypertensive outpatients were divided into two groups according to their AASI values: normal AASI group (AASI≤0.51, n=40) and high AASI group (AASI>0.51, n=32). The urinary micro-albumin, glomerular filtration rates (GFR) were measured and compared. The relationship between AASI and micro-albumin, GFR were tested with Pearson correlation and multiple Logistic regression. Results Compared with those in the normal AASI group, the patients in high AASI group showed a higher level of urinary microalbumin (P<0.05) and a reduction in GFR (P<0.01). AASI was positively correlated with urinary microalbumin (r=0.32, P<0.001), and negatively correlated with GFR (r=0.44, P<0.001). After adjusting the potentially confounding variables, the odd ratio (OR) of AASI to renal damage was 2.18 (P=0.008,95%CI:1.76~4.34). Conclusion The increase of AASI is associated with early signs of renal damage in patients with primary hypertension.

Objective To observe the impacts of valsartan combined with amlodipine or hydrochlorothiazide regimen on blood pressure variability (BPV) in elderly hypertensive patients.Methods Eighty elderly patients with hypertension were randomized into valsartan and amlodipine (the amlodipine group, n=38) or valsartan and hydrochlorothiazide (the hydro-chlorothiazide group,n=37) group.The 24-hour dynamic blood pressure was monitored at baseline, 6-week and 12-week after treatment for the blood pressure and blood pressure variability. The control rate of blood pressure was calculated at 6-week after treatment, and side effects were observed during the treatment.Results Values of 24 h systolic blood pressure (SBP), daytime SBP, nighttime SBP, morning SBP and 24 h systolic blood pressure variability (SBPV) were significantly low-er at 6-week and 12-week than those of baseline in both two groups(P<0.05). There was an interaction between the group-ing factors and time on 24 h SBP, daytime SBP, nighttime SBP, 24 h SBPV and daytime SBPV (P<0.05). At the 6 and 12-week treatment, 24 h SBP, daytime SBP, nighttime SBP and daytime SBPV were significantly lower in amlodipine group than those in hydrochlorothiazide group (P<0.05). At 12-week treatment, 24 h SBPV was significantly lower in amlodipine group than tjat in hydrochlorothiazide group (P<0.01). There were no significant differences in control rate of blood pressure and side effects between two groups. Conclusion Valsartan in combination with amlodipine or hydrochlorothiazide can both ef-fectively control BPV in elderly hypertensive patients, and valsartan conbined with amlodipine has better effects on lowering blood pressure and BPV.

Objective To study the effects of hypotensive resuscitation on microvascular perfusion in a clinically relevant model of uncontrolled hemorrhagic shock in pregnancy. Methods Thirty New Zealand white rabbits at 15 -25 days, pregnanal age were randomly divided into three groups; Group normal saline traditional aggressive resuscitation ( NS), traditional aggressive resuscitation in the prehospital phase with a large quantity of normal saline and Ringer's solution to maintain mean arterial pressure (MAP) at the approximately 80 mm Hg ( 1 mm Hg = 0.133 kPa) level: Group normal saline hypotensive resuscitation (NH) and group hypertonic hyperosmotic hypotension resuscitation (HHH), hypotensive resuscitation in the prehospital phase with a bolus dose of 4 ml/kg normal saline or hypertonic hydroxyl ethyl starch (10% hydroxyl ethyl starch + 7.5% NaCl), followed by Ringer's solution to maintain MAP at 60 mm Hg.Production pregnant rabbit model with hemorrhagic shock. The experiment consisted of four phases:basic phase (0 miniutes), shock phase (0- 30 miniutes), prehospital phase (30- 90 miniutes) and hospital phase (90- 180 miniutes). Measurements: (1) arteriole and venule diameter were continuously monitored by microcirculatory detecting instrument; (2) functional capillary density (FCD) of each phase was expressed by the percentage of opening capillaries segments relative to basic phase; (3) blood pH, BE PCO2, PO2 in pregnant rabbits were determined with a Medica Easy Blood Gas Analyzer. Results ( 1 )There were no significant differences among three groups in arteriole and venule diameter at baseline ( P >0.05 ). After hemorrhagic shock arteriole diameter were NS ( 50.8 ± 5.6) μm, NH (47.6 ± 3.7 ) μm, HHH (51.3 ±2.4)μm, respectively, with no significant differences between groups(P >0.05). At the end of prehospital resuscitation phase and hospital resuscitation phase, significant differences were found in arteriole diameter in group NS(52.8 ± 4.9, 56.0 ± 3.8 )μm, NH (61.3 ± 2.9, 65.4 ± 3.2 )μm and HHH group (67.0 ± 4.1,74.1 ± 4.8 )μm ( P < 0.05 ); after hemorrhagic shock venule diameter were NS(79.6 ± 7.0)μm, NH (75.3 ±5.3)μm and HHH(76.2 ±5.8)μm, respectively, with no significant differences between groups(P >0.05 ). At the end of prehospital resuscitation phase and hospital resuscitation phase,venule diameter were NS(81.1 ± 6.7, 84.4 ±6.0)μm, NH(82.8 ± 3.3, 85.4 ±4.3) μm and HHH (86.9 ± 5.8, 89.4 ± 6.8)μm, respectively, with no significant differences between groups ( P > 0.05 ). (2) The values of FCD in every groups were all 100%. After hemorrhagic shock FCD were NS(39.8 ±6.8)%, NH (43.9 ±4.0)%, HHH(44.0 ± 4.8)%, respectively, with no significant differences between groups(P >0.05); at the end of prehospital resuscitation phase and hospital resuscitation phase, FCD were NS(54.5 ±7.3,59.7 ±4.8)%,NH(63.1 ±5.8,70.3 ±5.6)% and HHH (80.5 ±6.9, 91.7 ±4.7)%,respectively, with significant differences between groups( P < 0.05 ). (3) Blood gas parameter: the values of blood pH, BE, PO2, PCO2 in pregnant rabbits in all groups were within normal bounds at basic phase. Shock phase induced typical hyperventilation in all groups, with increase of arterial PO2 and decrease of PCO2; at the end of hospital resuscitation phase, there were no significant difference among the three groups in the values of blood PCO2 ( P > 0.05 ); the values of blood PO2 at the hospital resuscitation phase were significantly lower in NS groups than corresponding values in the other groups (P < 0.05 ). After hemorrhagic shock there was significant metabolic acidosis as shown by decrease of pH, BE; at prehospital resucitation phase, pH, BE values tended to increase in all the groups but not reach to base period. At the end of hospital resucitation phase. The pH, BE value was significantly higher in NS group than those in the other two groups( P < 0.05 ) . (4) Median survival time in NS (2.1 ± 0.2) days group was significantly shorter than NH(3.0 ±0.3) days and HHH(3.6 ± 0.3) days group( P < 0.05). FCD at the end of the hospital resuscitation were significantly related with survival time ( r = 0.655, P = 0.000 ). Conclusion Compared with traditional aggressive fluid resuscitation, hypotensive resuscitation reduce constriction of arterial and venule diameter, increase FCD, alleviate metabolic acidosis and improve long-term survival Hypertonic hydroxyl ethyl starch resuscitation ameliorate microcirculation without improving survival rate.
