Objecttve To investigate the effects of snfentanil and ropivacaine used in labor combined spinalepidural analgesia(CSEA)and its influence on labor course and infants and its side effects.Methods 160 primiparas who chose deliver analgesia were randomly divided into two groups:group A intrathecal 5μg sufentanil plus saline up to 2.5ml,extradural 0.2μg/ml sufentanll plus 0.1% ropivacaine and saline up to 100 ml;group B extradural ropivacaine 1.5mg plus glucose 100g/L up to 2ml;group C have no analgesia.Then to investigate the effects of analgesia VAS scores,labor course duration,caesarean section rate,flooding volume,neonatal Apgar scores and its side effects.Results Compared with group C,the analgesia effects of group A and B were definitely(P<0.05,P<0.01);visual analogue score(VAS)at 5min,10min and 30min in group A were(3.4±1.2),(1.6 ±0.7)and(0.7 ±0.5)respectively,while in group B were(5.3±1.5),(4.3±1.8)and(3.1±1.7),which had significant difference in two groups(all P<0.01);they all could reduce the first labor course duration,caesarean section rate,and there were no difference with group C(P>0.05);and the flooding volume and neonatal Apgar scores had no differences(P>0.05).Conclusion Sufentanil and ropivacaine combined used in CSEA has stronger effect and longer duration without prolonged labor coulee and poor side effects,which would be a more perfect analgesia worth clinical application in obstetrics.

Optic nerve is composed by the axonal of retinal ganglion cells,there are no Schwann cells around it,and optic nerve belongs to the central nervous,so it cannot regenerate when injuried. In 1985 So and Aguayo have made a success in peripheral nerve retinal transplant,which completely changes the concept that optic nerve injury cannot regenarate. Currently nerve injury recovry has following several methods: use of neurotrophic factor,such as nerve growth factor,ciliary neurotrophic factor and brain-derived neurotrophic factor,etc. These factors could promote the regeneration and repair of retinal ganglion cells; treatment of gene correction and gene regulation,by changing the expression of host gene,reduce the effect due to the disease,slow the progress of the disease course or provide protection against the disease; neural stem cell transplantatin and tissue-engineered Schwann cell transplantion. But these treatments are still at the stage of animal experiment,how timely and effctively reduce the apoptosis and increase the survival rate of ganglion cells,even further promote nerve regeneration and recovery,there is still not a perfect method so far.

Objective To evaluate the values of clinical application of color Doppler ultrasound in the diagnosis and treatment of iatrogenic femoral artery pseudoaneurysm (IFAP) in the elderly following percutaneous transluminal coronary angioplasty(PTCA). Methods A tota.of 35 patients aged(73.8±1.3) years with IFAP after PTCA were examined by color Doppler ultrasound.All cases were treated by compression simply for blocking blood flow with probe guided by ultrasound,and the failed cases were injected Reptilase into the lumen of pesudoaneurysm. Results 35 patients were diagnosed as IFAP by color Doppler ultrasound and the coincidence rate with clinical diagnosis was 100% (35/35).Among all patients,31 cases were cured by simply compression guided by ultrasound and 3 cases were cured hy the injected reptilase into lumen,the cure rate was 97.15%(34/35).One cases was cured by surgery after failure to treat by the two above methods.34 cases (97.2%)were verified into occlusio by ultrasound after 24-48 h of treatment. Recurrence and other serious complications were not found during follow-up of 3-6 months. Conclusions Color Doppler ultrasound can be used for the preferred method in accurate diagnosis and effective cure of IFAP following PTCA in the elderly.

Objective To explore the optimal time for clinical interventions on full-term or nearterm pregnant women with premature rupture of membranes(PROM). Methods A retrospective study was conducted on clinical data of 903 healthy, full-term or near-term (gestational age ≥ 35 weeks), singleton pregnant women with PROM, who admitted to our hospital from January 1, 2005 to December 31, 2009. All subjects were divided into 6 groups: women in group 1 were those fell into spontaneous labor within 6 h after PROM (n=269, 29.8%); women in group 2 were in spontaneous labor between 6 to 12 h after PROM (n= 161, 17.8%) ; women in group 3 were in spontaneous labor at 12 to 24 h after PROM (n = 75, 8. 3%); In group 4 oxytocin was administered for induction for women not in labor at 6 to 12 h after PROM (n= 124, 13.7%) ; Group 5 included those women who were not in labor at 12 to 24 h after PROM and oxytocin induction was offered (n=98, 10. 9%);Group 6 consisted of those women who were not in labor over 24 h after PROM and oxytocin induction was offered (n = 176, 19. 5%). The maternal and neonatal complications and outcomes of all pregnancies were reviewed and compared. Results Among the 903 cases, the total number of women without any medical interventions was 681, among which 505 (74.2%) fell into spontaneous labor, including 430 (63.2%) within 12 h with a cesarean section rate(CSR) of 20.7%(89/430), 75 (11.0%) at 12-24 h after PROM with the CSR of 50.7% (38/75), and 176 (25.8%) did not go into labor spontaneously (group 6) with a CSR of 70. 5% (124/176). (2) Among the 930 women, 398were induced at 6, 12 and 24 h after PROM. The CSR, incidence of intrauterine infection, puerperal morbidity and perinatal mortality rate in group 5 were significantly lower than those of group 6 [CSR:52.0%(51/98) vs 70. 5%(124/176); intrauterine infection: 6. 1%(6/98) vs 22. 7%(40/176);puerperal morbidity: 6. 1% (6/98) vs 19.9% (35/176); perinatal mortality: 7. 1% (7/98) vs 20.5%(36/176),all P<0. 01], but no difference was found in the incidence of postpartum hemorrhage [1.0%(1/98) vs 4.0%(7/176), P>0.05]. Conclusions Intervention is not recommended within 12 h after PROM in full term or near term gravidas. However, induction of labor should be offered thereafter. However, the CSR and incidence of maternal and neonatal complications rise up if induction of labor postponed to 24 h after PROM.

Objective: To investigate the effects of fosinppril on myocardial cell apoptosis and apoptosis-associated gene expression in chronic heart failure (CHF) rats.
Methods: CHF model was established by partially banding of abdominal aorta superior to renal artery. The experimental rats were randomly divided into 3 groups: Sham operation group and CHF group, the rats in both groups received stomach normal saline; Fosinopril group, the rats received stomach fosinopril 10 mg/kg?d.n=10 in each group and all animals were treated for 8 weeks. LVEDP, ±dp/dtmax and LVMI were examined, left ventricular myocardial cell apoptotic index (AI) was measured by TUNEL method, Bcl-2 and Bax protein levels were detected by immunohistochemistry and caspase-3 protein expression was assessed by Western blotting.
Results: Compared with Sham operation group, CHF group had increased LVEDP, LVMI, AI, elevated protein expressions of Bax and Caspase-3,P<0.01; while decreased ±dp/dtmax, reduced protein expression of Bcl-2 and the ratio of Bcl-2/Bax,P<0.01. Compared with CHF group, Fosinopril group presented decreased LVEDP, LVMI, AI, reduced protein expressions of Bax and Caspase-3,P<0.01; while increased ±dp/dtmax, elevated protein expression of Bcl-2 and the ratio of Bcl-2/Bax, P<0.01.
Conclusion: Fosinopril may inhibit myocardial cell apoptosis which occurred during CHF, by up-regulating Bcl-2 expression and down-regulating expressions of Bax and Caspase-3 in CHF rats, therefore improve the cardiac function.
