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.

Objective To examine the effect of endothelial colony-forming cells conditioned medium(ECFCs-CM)on biological function of human dermal fibroblasts(HDFs). Methods Human cord blood derived-ECFCs were isolated and identified based on the previous studies. The cytokines in ECFCs-CM were detected using a cytokines antibody array. HDFs were cultured with ECFCs-CM,using serum free EBM-2 as control. The proliferation of HDFs was examined by Cell Counting Kit-8(CCK-8)and the migration was assessed by scratch test assay. The apoptosis of HDFs was detected by flow cytometry. Results The cells isolated from human cord blood demonstrated typical characteristics of ECFCs. The cytokines antibody array indicated that ECFCs-CM contained large amounts of secreted cytokines such as PDGF-BBand EGF. Compared with the control group,the HDFs cultured with ECFCs-CM showed improved proliferation and migration ability. The number of apoptotic cells was smaller than that of the control group under the environment of serum starvation. Conclusion ECFCs-CM can promote the proliferation and migration of HDFs and inhibit the apoptosis of HDFs under the environment of serum starvation.

Objective To analyze the clinical data of recipients over 15 years after renal transplantation,and to find the factors that affect the long-term survival of recipients after renal transplantation.Method Before June 30,2000,326 renal transplant recipients in our hospital were collected retrospectively.The risk factors which affect the survival of kidney transplant recipients and kidney were analyzed from four dimensions.A Cox model was established to analyze these multi factors.Result Cox hazard model indicated that advanced age (P=0.010,RR =1.052),AMR (P＜0.001,RR =18.311),nonadherence (P =0.001,RR =2.854),smoking (P =0.025,RR =2.097)were the risk factors for recipients' survival.Using immunosuppressive regimen FK506 + MMF+ Pred (P =0.019,RR =0.433),or CsA + MMF + Pred (P =0.019,RR =0.413) was the protective factor for recipients' survival.Nonadherence (P＜0.001,RR =5.645),and diabetes (P＜0.001,RR =3.310) were the risk factors of grafts' survival.Using immunosuppressive regimen FK506 + MMF + Pred (P＜0.001,RR =0.236),or CsA + MMF + Pred (P =0.002,RR =0.317) was the protective factor of grafts' survival.Conclusion To enhance the long-term outcome of recipients and grafts,the individualization of immunosuppressive regiments and controlling of the chronic diseases progress by changing the unhealthy life style are cutting on edge.
