OBJECTIVETo explore the factors associated with perinatal death of hepatic diseases in pregnancy (HDIP) and make feasible suggestions and measures for perinatal care of high risk patients.

METHODSThe 80 perinatal death cases of hepatic diseases in pregnancy (HDIP) during 1991-2000 in our hospital were analyzed retrospectively.

RESULTSThe perinatal mortality of HDIP in our hospital during the last 10 years was 17.99 approximately 65% was in utero death. Perinatal mortality was different between male (21.64%) and female (10.11%) (P<0.01). Compared first 5 years with last 5 years author found that the perinatal mortality of HDIP had no significant decrease (P>0.05). The perinatal mortality in city and suburbs had decreased, while in the floating population from other provinces the perinatal mortality had increased. The perinatal death was mainly caused by pregnancy induced hypertension (PIH) and asphyxia. But for the HBV carrier mothers the causes of death included umbilical cord problems, premature rupture of membrane and asphyxia.

CONCLUSIONSThe perinatal death mortality was increased by HDIP, deaths were essentially associated with pregnancy induced hypertension and asphyxia and the floating population and male gender were high risks. To enhance the management of HDIP or immigration, take effective therapies of hepatitis and improvement of resuscitation of newborns are critically important.

Objective To investigate the value of myocardial contrast echocardiography(MCE)combined with high-dose dobutamine stress echocardiography(DSE)in the early diagnosis of coronary artery disease(CAD).Methods The dobutamine stress MCE and SonoVue contrast infusion were performed before an elective percutaneous coronary intervention in 38 patients with suspected CAD.The total and regional perfusion were scored as normal or abnormal and attributed to the three main epicardial coronary arteries using a 16-segment left ventricular model.Results An intermediate stress level was obtained in 22(58%)patients,and 9(24%)patients were obtained with peak stress.Twenty seven of 38 patients were diagnosed as CAD by quantitative coronary angiography.A perfusion defect was detected in 89% of the patients at peak stress,compared to 37% at baseline,there was significant difference(χ2=15.565,P<0.01).ConclusionsThe MCE combined with DSE can increase the sensitivity of myocardial ischemia detection.As a new non-invasive method,MCE combined with DSE could be used in the early diagnosis of CAD.

Objective Analyse the change of left ventricular (LV) longitudinal and radial strain in patients with aortic regurgitation (AR) and discuss the relationship between the 2D strain parameter and the filling and ejection of LV. Methods Thirty healthy controls and 45 patients with AR (24 patients with moderate AR and 21 with severe AR) were enrolled in this study, LV systolic global peak radial strain(GRS), systolic global peak longitudinal strain(GLS) and systolic peak longitudinal strain(S), systolic peak longitudinal strain rate(SRs), early diastolic peak longitudinal strain rate(SRe) of every segment were measured or calculated using 2D-STE, early and late diastolic transmitral flow velocity (E, A) were recorded by pulsed Doppler echocardiography and early diastolic mitral annular velocity (Ea) were assessed by tissue Doppler imaging,the E/A and E/Ea ratio were calculated. Discuss the relationship of GLS and LV ejection fraction (LVEF), GLS and E/Ea using the Pearson correlation analysis. Results The GLS were (-20.09±1.47)%, (-18.68±1.52)%, (-12.56±3.25)%and the GRS were (46.71±7.65)%, (43.01±5.95)%, (28.52±6.13)% in control group, patients with moderate and severe AR (MAR group and SAR group) respectively. There were significant differences among the groups (F =82.08,47.69, both P < 0.01) as following:SAR group with control group and MAR group [ q=17.56,13.60 (GLS), q=13.44, 10.20 (GRS), all P<0.01),MAR group and control group [ q=3.42 (GLS), P<0.01]. The SRs of the apical segment were (-1.24±0.22)s-1, (-1.19±0.25)s-1, (-1.04±0.28)s-1 in control group,MAR group and SAR group respectively. There were significant differences among the groups (F=4.47, P < 0.05) as following:SAR group with control group and MAR group ( q=4.02,3.28, both P<0.01). The S, SRe of apical segment and the S,SRs,SRe of basal and midventricular in MAR group were all lower than the control group ( q=4.42, 5.01, 3.48, 3.24, 4.78, 4.12, 3.61, 6.72, all P < 0.01). Pearson correlation analysis revealed the GLS had a relationship with LVEF and E/Ea ( r=-0.73, 0.64, both P<0.01). Conclusion The reduced longitudinal strain and strain rate could detect LV dysfunction in patients with AR in early stage and the GLS had the ability to reflect the diastolic filling and systolic ejecting of the LV.

The main treatment strategies for chronic pancreatitis in young patients include therapeutic endoscopic retrograde cholangio-pancreatography (ERCP) intervention and surgical intervention. Therapeutic ERCP intervention is performed much more extensively for its minimally invasive nature, but a part of patients are referred to surgery at last. Historical and follow-up data of 21 young patients with chronic pancreatitis undergoing duodenum-preserving total pancreatic head resection were analyzed to evaluate the outcomes of therapeutic ERCP intervention and surgical intervention in this study. The surgical complications of repeated therapeutic ERCP intervention and surgical intervention were 38% and 19% respectively. During the first therapeutic ERCP intervention to surgical intervention, 2 patients developed diabetes, 5 patients developed steatorrhea, and 5 patients developed pancreatic type B pain. During the follow-up of surgical intervention, 1 new case of diabetes occurred, 1 case of steatorrhea recovered, and 4 cases of pancreatic type B pain were completely relieved. In a part of young patients with chronic pancreatitis, surgical intervention was more effective than therapeutic ERCP intervention on delaying the progression of the disease and relieving the symptoms.

Objective To investigate the expression of cyclin kinase inhibitor P21~(WAF1) and P27~(KIP1)in children with acute leukemia and its clinical significance.Methods A total of 32 hospitalized children with acute leukemia(AL) were included in this study.Their bone marrow samples were collected before chemotherapy and individual patient was detected after complete remission(CR).The method of immunocytochemistry was used to estimate the expression of P21~(WAF1) and P27~(KIP1).Both positive percentage and intensity of the cells were counted.Results Findings showed that the positive ratios of P21~(WAF1) and P27~(KIP1) in total samples,ALL samples and AML samples were lower than the control group(P

To investigate the therapeutic effects and associated complications of allogeneic peripheral blood stem cell transplantation (allo-PBSCT). 40 patients with various malignant hematopoietic diseases received allo-PBSCT. The preparative regimens were based on BUCY2 or modified BUCY2. The acute graft-versus host disease (aGVHD) was prevented by cyclosporin A and short-term MTX regimen in all patients. Two patients from donors with one fully mismatched HLA on DRB1 locus and 4 from unrelated donor also administered Zenapox (CD25 MAb) at dosage of 1 mg/kg every day on the day before transplantation and day 4 after transplantation. These 6 patients were also treated with mycophenolate mofetil (MMF). Transfusion of the donor cells: The median of the transfused nucleated cells was 5.38 x 10(8)/kg and that of the CD34+ cells was 7.8 x 10(6)/kg respectively. All the patients gained hematopoietic reconstruction except one who died of infection before engraftment. Seven patients got II degrees-IV degrees aGVHI) and the incidence was 17.5%. Fourteen patients got cGVHD and the incidence was 53.8% in the patients who survived over 6 months. Twenty-eight patients had fever or other characteristics of infection. The median follow-up time was 13.8 months. The incidence of transplantation related mortality (TRM) was 17.5% and 2 patients relapsed (5.0%). It was concluded that allo-PBSCT can reconstruct hematopoiesis quickly and is a favorable therapeutic method for leukemia.

BACKGROUND: Coronary microembolization (CME) is a serious complication following percutaneous coronary intervention (PCI) in patients with acute coronary syndromes. The use of metoprolol before PCI can significantly protect ischemic myocardium from myocardial damage, but the function of metoprolol in the treatment of CME is not entirely clear. This study was to explore the effect and significance of metoprolol on myocardial apoptosis and caspase-3 activation after CME in rats. METHODS: Thirty rats were randomly divided into three groups including sham-operation (control group), CME plus saline (CME group), CME plus metoprolol (metoprolol group), 10 rats for each group. The CME group was induced by injecting 3000 polyethylene microspheres (42 μm) into the left ventricle during a 10-second occlusion of the ascending aorta; the control group was injected with physiological saline instead of microembolization ball; the metoprolol or saline group was given three intravenous bolus injections before CME. Echocardiography, TUNEL staining, and Western blotting were used to evaluate cardiac function, proportion of apoptotic cells and activation of caspase-3 respectively at 6 hours after operation. RESULTS: Echocardiographic parameters displayed that the metoprolol group improved cardiac function significantly compared with the CME group (P<0.05). The myocardial apoptotic rate of the CME group as wel as the contents of activated caspase-3 increased significantly (P<0.05), both of which were ameliorated significantly by metoprolol treatment (P<0.05). CONCLUSIONS: This study demonstrates that metoprolol can protect the myocardium during CME in rats by inhibiting apoptosis and improving cardiac function. These results suggest that the inhibition of apoptosis can be a potential therapeutic strategy for the treatment of CME.
