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.

cases of focal nodular heperplasia of the liver were studied with HE staining and immunohistochemistry. The patient population was composed of 12 males and 5 females, aged 13 to 71 years. The main symptom was abdomimal pain or discomfort. 9 patients were misdiagnosed as hepatic cell carcinoma (HCC) before operation. Histologically, 14 cases were of classical form, and 2 cases were of telangiectatic form, and 1 case mixed form. The classical form of FNH was defined by the presence of 4 characteristic histologic features: nodular central stellate scar, abnormal nodular architecture, malformed vessels, and cholangiolar proliferation. The causes of focal nodular hyperplasia of the liver were briefly discussed.

OBJECTIVE: To study the therapeutic effect of treating knee arthropathy with total knee arthroplasty using rotating-platform knee prosthesis. METHODS: A total of 62 patients (74 knees) in Provincial Hospital Affiliated To Shandong University from January 2005 to January 2009 were selected, including 36 males (41 knees) and 26 females (33 knees), aged 52-79 years, mean aged 61.5 years; 28 cases with left knee, 22 cases with right knee and 12 cases of both knees. The cases were composed of 34 cases with osteoarthritis, 21 cases with rheumatoid arthritis and 7 cases with traumatic arthritis. All the patients received the total knee arthroplasty for the first time using rotating-platform knee prosthesis, no replacement of the patella. The clinical results of pre-operetion and after-operation were evaluated by the HSS knee rating score system. RESULTS: All the patients were followed-up for averaged 22 months (3-48 months) after operation. Incisions of all the cases were healed, and there was no infection and hematoma. Lower extremity deep venous thrombosis occurred in 2 cases at 3 days after operation. Swelling disappeared through drug treatment 10 days later. Pain and function of all the patients were obviously ameliorated after operation. The average HSS knee rating score was 44.99 (from 34 to 58) before total knee arthroplasty, which was improved to 88.78 (from 69 to 98), and the good-to-excellent rate was 98% (excellent 45 cases, good 16 cases, average 1 case). There were no signs of prosthetic dislocation or loosening in the X-ray films. CONCLUSION: Total knee arthroplasty using rotating-platform knee prosthesis owns advantages of easy surgical operation, tess complications, good recovery and satisfactory results in a short-term.
