Objective To investigate the relationship between placental endoglin expression and the pathogenesis of severe preeclampsia (SPE). Methods Forty nine pregnant women with SPE and 40 normal pregnant controls were collected in Peking University First Hospital from January 2006 to January 2008,among which,nine SPE patients complicated with fetal growth restriction (FGR),six with hemolysis,elevated liver enzymes and low platelets syndrome (HELLP syndrome) and 12 with heavy proteinuria. The expression of placental endoglin was detected and semi-quantified by immunohistochemistry.Data were analyzed by independent sample t test. Results Endoglin was presented on cell membranes of placental syncytiotrophoblasts and vascular endothelial cells. The endoglin density of SPE group was higher than that of control group (0.1621± 0.0029 vs 0.1576 ± 0.0038,t=- 6.367,P＜0.05).No significant difference in endoglin density was found between FGR group and non-FGR group (0.1611±0.0026 vs 0.1623±0.0029,t=1.107,P＞0.05) ; neither did the heavy proteinuria group and non-heavy proteinuria group (0.1611±0.0032 vs 0.1624±0.0027,t=1.350,P＞0.05).The endoglin density of HELLP group was lower than that of non-HELLP group (0.1595±0.0032 vs 0.1625±0.0027,t=2.495,P=0.016). Conclusions The elevated placental endoglin expression might contribute to the pathogenesis of SPE.

0. 05). No significant difference was found in maternal and neonatal complications between the ANCA( + ) and ANCA(－) subgroups in S-PE subjects. But those 4 cases who developed renal function insufficiency patients were ANCA( + ). Conclusions ANCA might be associated with renal diseases in preeclampsia women, and further studies is required to determine whether ANCA is involved with the pathogenesis of preeclampsia.

OBJECTIVE:To explore the basic principles,advantages and application prospects of Bayesian mixed treatment comparison (MTC),and provide theoretic support for making reasonable decisions of pharmacoeconomics. METHODS:The prob-lems existing in model and method that had been used in the study of pharmacoeconomics as starting point,literature research was used to sort out the domestic development and applications of MTC and study its application and development prospect. RESULTS &CONCLUSIONS:The evaluation methods of pharmacoeconomics play an important role in selection of essential medicines,medi-care insurance directory medicines,basic health and basic public health programs,the results directly affect the total effective rate of medical resources’configuration. The current research models cannot effectively solve the problem,for example,decision tree model is difficult to make evaluation of long-term treatment;Markov model and the use of multiple attribute utility theory are restricted by the model parameters;discrete event simulation is limited because it depends on the epidemiological study and clinical trial. MTC, an extension approach of the traditional Meta-analysis,is an effective new method developed recently to analyze and compare the di-rect or indirect evidence of several different clinical treatment factors in order to make a comprehensive evaluation of the various inter-ventions in the absence of evidence support. So the MTC can make up for the limitation of current evaluation methods.

Objective To investigate the incidence changes, clinical characteristics and pregnant outcomes of pernicious placenta previa. Methods A retrospective cohort analysis on 316 cases with placenta previa in the Peking University First Hospital from January 2008 to December 2014. The research group were 60 cases with the patients of placenta previa with the history of cesarean section, and the control group were placenta previa without the history of cesarean section. Compared with the incidence, intraoperative blood loss, the pregnancy outcomes and so on. Results (1) The average incidence rate of placenta previa during the past 7 years was 10.96‰ (316/28 837). And the cases of pernicious placenta previa was 60 (2.08‰, 60/28 837), the incidence of pernicious placenta previa was rising from 2008 to 2014 (0.91‰-3.08‰). (2) There were 145 cases of placenta privia had been translation from other hospitals in the past 7 years. The referral rate of pregnant women with placenta previa was 45.9%(145/316), and the referral rate of pernicious placenta previa (63.3%, 38/60) was significantly higher than that of non-pernicious placenta previa group (41.8%, 107/256; χ2=9.080, P=0.003). Referral the outcomes of these patients were good, and no maternal death occurred. (3) The placenta in the research group were mainly adhered in the front wall of the uterine, and the incidence was 38.5%(15/39), higher than that in the group of non-pernicious placenta previa (12.1%, 21/174; χ2=57.636, P<0.01). The incidence rate of complicated placenta increased in research group was 53.3% (32/60), higher than that in the group of non-pernicious placenta previa, compared with the control group, there was significant difference (15.6%, 40/256; χ2=39.041, P<0.01). (4) The incidence of blood loss was more than 1 000 ml, blood transfusion rate, the rate of hysterectomy and the rate of asphyxia of newborn in the research group were respectively 41.7% (25/60), 38.3%(23/60), 8.3%(5/60), 15.0%(9/60), and the incidence of the group of non-pernicious placenta previa were respectively 4.7%(12/256), 12.9%(33/256), 1.2%(3/256), 8.6%(22/256), compared those in other two groups, there were not significant difference (P<0.05). Conclusions The incidence rate of placenta previa increased year by year, patients with placenta previa has a history of cesarean section often combined with placenta in anterior wall of the uterus, and often with poor pregnancy outcomes. Hierarchical referral system is an effective means to reduce the mortality of the pernicious placenta previa.

BACKGROUND: Micro-implant screws as an absolute anchorage, instead of traditional anchorage that requires patient's high matching and affects beauty, has been paid more attention.OBJECTIVE: To compare the changes in 3 different places following implantation of micro-implant screws. DESIGN, TIME AND SETTING: The controlled study was performed at the Hospital of Stomatology Affiliated to Foshan College of Sciences and Technology from January 2004 to December 2007.PARTICIPANTS: A total of 45 patients who demand powerful anchorage during the orthodontic treatment were assigned to 3 groups: free gingiva group, mucogingival junction group, and mucosa group.METHODS: By using incomplete flap micro-implant screw implantation, micro-implant screws were implanted in the free gingiva, mucogingival junction and mucosa, with 30 screws in each area.MAIN OUTCOME MEASURES: Loosening and defluvium of micro-implant screws were measured. Pain duration and degree were determined in patients undergoing implantation of micro-implant screws 7 days following surgery. Soft tissue surrounding the micro-implant screws and bleeding rate during probing were detected 56 days following surgery.RESULTS: The number of screw loosening was greatest in the free gingiva group (9 screws), while lowest in the mucogingival junction group (2 screws). Patients suffered from severe flare and pain in the mucosa, and the reaction was mild in the free gingiva following implantation. The reaction was not obvious, but severe pain was found in the mucogingival junction following implantation compared with the free gingiva. Soft tissue surrounding the micro-implant screws and bleeding rate during probing were greater in the mucosa group than in the free gingiva group and mucogingival junction group (P<0.05).CONCLUSION: The incomplete flap micro-implant screws in the mucogingival junction contribute to the increase in success implantation rate and the decrease in inflammatory degree, and prevent the occurrence of potential risk.

Objective To learn students' satisfaction with the general education courses, discuss the problems in comprehensive general education courses in local medical colleges , and provide the basis and reference for the medical general education courses reform. Methods Using the stratified random sampling method, self-designed questionnaire to local medical colleges of 575 different professions stu-dents. The questionnaire had the total of 54 topics whose contents were related to the basic situation aware-ness and satisfaction, the demand for general education courses, general education curriculum problems and suggestions. The survey data were analyzed using SPSS 19.0 software and the results were expressed by the relative number(rate and percentage). The differences between different majors and different grade student satisfaction were analyzed by using rank-sum test, showing statistical significance(P<0.05). Results The total satisfaction was not very high, only 219 students(38%) were satisfied with general curriculum;256 students(45%) thought it didn't matter whether to set general education courses;100 students(17%) were not satisfied. In addition, satisfaction with different grades was undifferentiated (P=0.798), but there was a statistical difference among the students of different professions(P=0.007). Conclusion The general education curriculum of medical schools should not blindly pursue being wide and full. Instead, it should be built from three aspects such as core curriculum, flexible teaching methods, teaching methods reform to enhance teaching effectiveness.

Objective To investigate the effect and mechanism of low-dose remifentanil(RF)on systemic artery tension of baby rabbit with septic shock.Methods Thirty-six systemic artery strips were prepared from 12 baby rabbits and randomly divided into 6 groups:control group,lipopoly-saccharide(LPS)group,RF group,LPS + RF group,NG-nitro-L-arginine(L-NNA)pretreated group,LPS + L-NNA pretreated group.Each group had six rings(n =6).The effect of low-dose RF on the systemic artery tension of baby rabbit with septic shock was observed with isolated vascular ring technique.The change was also obversed after L-NNA pretreatment.Results In control group:the relaxant rates after low-dose RF at the time point of 5 min,10 min,20 min were(18.48±3.96)％,(23.63±4.42)％,(28.33±3.73)％(P＜0.05),compared with NS group.After pretreatment with L-NNA,RF-related relaxant rates of systemic arteries decreased significantly to(8.15 ± 1.01)％,(13.08 ± 1.46)％,(18.54 ±2.94)％(P ＜ 0.05).In LPS group,low dose RF(4 μg/L)did not bring out any response to systemic arteries(P ＞0.05).The tension was not affected with pretreatment of L-NNA(P ＞ 0.05).Conclusion These results suggest that low dose RF has relaxant effect on systemic arteries of baby rabbits,and NO may be involved.Low dose RF has no relaxant effect on LPS-pretreated systemic arteries of baby rabbits,and it has no association with NO.

Objective To discuss the serum endoglin expression in severe pre-eclampsia and eclampsia women and their relationships. Methods Forty-two severe pre-eclamptic patients and 4 eclamptic patients in Peking University First Hospital from Dec. 2005 to Dec. 2007 were enrolled in the study group, with the mean gestational week of 35 ± 4, the mean age of 29.3 ± 5.7 and the mean BMI (30.1 ± 4.1 ) kg/ m2. This group included 25 cases of early onset pre-eclampsia, 21 cases of late onset pre-eclampsia, 8 cases of fetal growth restriction and 5 cases of HELLP syndrome. The control group included 29 cases of normal pregnant women during the same period, with the mean gestational week of 33±4, the mean age of 30.7± 3.4 and the mean BMI(27.2±2. 2) kg/m2. Peripheral serum endoglin was determined by ELISA in these two groups. Results (1)There is positive correlation between serum soluble endoglin level and the gestational weeks during 27 to 37 gestational weeks in the control group (r=0.79, P<0.05), but there is no distinct relationship in the study group (r=0.31, P>0.05). (2) Serum endoglin level of severe pre-eclampsia group was higher than the normal group [(14.2±5.6)μg/L vs. ( 10.9 ± 4.2 ) μg/L, P<0.05]. (3) Serum endoglin level of early onset group did not differ from late onset group [(14.3±5.7)μg/L vs. (13.6±5.0)μg/L, P >0.05]. (4) No difference of serum endoglin between HELLP group and non-HELLP group was found [(10.1±2.9) μg/L vs. ( 14.4±5.4) μg/L, P>0.05 ]. (5) Serum endoglin level of FGR sub group was higher than non-FGR sub group [(17.3±6.1) μg/L vs. (13.0±4.8) μg/L, P < 0.05] in the stady group. Conclusion The elevated peripheral serum endoglin level may contributes to the pathogenesis of severe pre-eclampsia and FGR, but not the week of the onset of the disease.
