Objective To establish the PDGF-BB-induced proliferation of rat pulmonary artery smooth muscle cells(PASMCs), and investigate the effects of the AMPK agonist AICAR on the cell cycle of PASMCs, in order to search new drugs for prevention of pulmo-nary vascular remodeling. Methods 20ng/ml PDGF-BB was used to induced the proliferation of PASMCs, and the effect of 0. 5mmol/L AICAR on the proliferation of PASMCs was observed. Western blot was used to detect the total and phosphorylated AMPK. The prolifer-ation of PASMCs was determined by CCK-8. The mRNA expression of cyclinD1, cyclinE and CDK2/4/6 were detected by flow cytometry analysis cell cycle,quantitative real-time PCR. Results Western blot Results indicated AICAR could promote the activation of AMPK. CCK-8 test Results showed that AICAR blocked the proliferation of PASMCs induced by PDGF-BB. Flow cytometry analysis indicated that AICAR arrested the cell cycle in G0/G1 to S phase. RT-PCR Results demonstrated that AICAR inhibited the mRNA expression of cy-clinD1, cyclinE and CDK2/4/6. Conclusion The AMPK agonist AICAR can block the proliferation of PASMCs induced through arrest cell cycle in G0/G1-S phase by regulation the mRNA expression of cyclin D1, cyclinE, CDK2/4/6, and AICAR has a potential applica-tion in preventing pulmonary vascular remodeling.

Objective　To investigate the changes and its clinical significance of plasma neuropeptide Y(NPY) concentration in patients with pregnancy induced hypertension (PIH). Methods　Plasma NPY levels were detected by radioimmunoassay in 30 patients with PIH, 20 normal non-pregnant women and 23 normal pregnant women. The PIH group was subdivided into mild, moderate and Severe subgroups, and the NPY concentration was also measured in these subgroups respectively at admission and one week after delivery. Results　The plasma NPY levels in patients with PIH ［(164.16±68.32) ng/L］ were significantly higher than those of normal non-pregnant women and normal pregnancies ［(86.60±20.65) ng/L, (82.42±12.46) ng/L, P<0.01, respectively］. There was significant difference among plasma NPY levels among the patients with mild, moderate, and severe PIH at admission (P<0,01). At one week after delivery the concentrations of plasma NPY were significantly decreased in the moderate and severe subgroups compared with the value measured at admission (P<0.01). Moreover, the NPY levels in patients with severe PIH after delivery were still higher than those of normal non-pregnant women. Conclusions　The results suggested that the level of NPY in plasma is increased in women with PIH. Elevated plasma NPY levels may play a key role in the development of PIH.

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.
