Objective To evaluate the pregnancy outcome of women with pulmonary arterial hypertension (PAH).Methods The medical records of 103 pregnant women with PAH admitted to Beijing Anzhen Hospital from January 2007 to March 2011 were studied retrospectively.Results (1) Degree of PAH and cardiac function.Among the 103 PAH,92 cases were patients with congenital heart disease and 13 cases were with rheumatic heart disease.They were divided by color doppler ultrasound into mild PAH group (34 cases),moderate PAH group (22 cases) and severe PAH group (47 cases).Per heart function classification,21 cases (20.4％,21/103) were class Ⅰ,44 cases (42.7％,44/103) were class Ⅱ,27 cases (26.2％,27/103) were class Ⅲ and 11 cases (10.7％,11/103) were class Ⅳ.More patients were class Ⅲ and Ⅳcardiac function in the severe PAH group than in the mild and moderate PAH groups,with statistically significant difference (P ＜ 0.05).(2) Delivery mode.There were 44 term delivery and 23 preterm birth in the 103 PAH patients.Sixty-three cases (94％,63/67) received cesarean section and 4 cases had vaginal delivery.There were 36 iatrogenic abortion (35.0％,36/103).The iatrogenic abortion rate in the severe PAH group was significantly higher than those in the mild and moderate PAH groups (P ＜ 0.05).(3) Perinatal outcomes.The full-term delivery rates in the mild and moderate PAH groups [80％ (20/25) and 14/17] were significantly higher than the severe PAH group (40％,10/25),respectively (P ＜ 0.05).And the premature birth rate of the severe PAH group(60％,15/25) was significantly higher than the mild and moderate PAH group [20％ (5/25)and 3/17,P ＜ 0.05].There were 4 neonatal asphyxia.The birth weight of mild,moderate and severe PAH groups were (3071 ± 443),(2910 ± 619) and (2381 ±589) g,respectively.The birth weight in the severe PAH group was significantly lower than the mild and moderate PAH groups (P ＜ 0.05).(4) Mortality.Nine cases naternal death happened,with a mortality of 8.7％ (9/103).All of them were severe pulmonary hypertension patients.Conclusions PAH is a serious complication during pregnancy.Women with mild PAH and normal cardiac function could continue pregnancy to full-term.Women with moderate PAH might continue pregnancy to 32 weeks under intensive care,cesarean delivery is preferable.Pregnant women with severe PAH should terminate pregnancy because of the high mortality.

OBJECTIVE: To investigate the bacteria distribution, drug bacterial sensitivity characteristics of the rural chronic rhinosinusitis (CRS). And to explore the effect of antibiotic on pathogenic bacteria culture. METHOD: Choose nasal sinus secretions from 115 CRS patients living in rural areas. Aerobic bacteria culture, anaerobic bacteria culture and drug sensitive test were procedured for each sample. At the same time the use of antibiotics nearly 2 months and nearly 2 weeks were collected. RESULT: Among one hundred and fifteen specimens, 17 kinds of germs were detected in 37 cases, the positive rate of aerobic bacteria was 32.17%. Staphylococcus aureus and epidermis staphylococcus aureus the most common type of aerobe in CRS patients at rural areas. There was negative result in the anaerobic bacteria culture of 17 maxillary sinus specimen. The cases of using antibiotics nearly 2 months was up to 90, accounting for 78.26%. Nearly 2 weeks, 73 cases, accounting for 63.48%. The chi-square analysis showed high bacterial culture rate, in chronic rhinosinusitis with nasal polyps (CRSwNP group), which revealed correlation between bacterial infection factors and nasal polyps formation. For CRS patients with positive result of bacterial culture, they were sensitive to ofloxacin, cefotaxime, organism, ciprofloxacin, magnitude cephalosporin, and were drug fast to penicillin G, ampicillin, erythromycin. CONCLUSION No specific differences was found in the bacteria distribution of rural CRS. antibiotics abusage in rural CRS patients and the anaerobic bacteria culture techniques is the main factor resulting in low culture rate. Rational use of antimicrobial agents should be established on the basis of the bacterial culture and drug sensitive test.
