Objective:To investigate the prevention and treatment status of venous thromboembolism (VTE) of pregnant women in general hospitals and specialized hospitals in China.Methods:This study was a cross-sectional survey about VTE prevention and treatment in 112 hospitals across China from January 1st to December 31st, 2019, including general information, resource accessibility, hospital system and strategy. According to the characteristics, the hospitals were divided into general hospital group (70 hospitals) and specialized hospital group (42 hospitals). The basic information, VTE diagnosis and treatment resources, prevention systems and the preference of the VTE risk assessment form of the two groups were compared. Logistic regression was used to analyze the proportion of VTE incidence and related factors in the two groups of hospitals.Results:(1) The median annual delivery volume of the general hospital group was significantly lower than that of the specialized hospital group (3 428 vs 9 969 cases, P<0.01), the diagnostic accessibility of CT pulmonary angiography (CTPA) was significantly higher than that of the specialized hospital [92.9% (65/70) vs 59.5% (25/42), P<0.01], and the proportion of obstetric VTE risk assessment was significantly higher than that of the specialized hospital group [85.7% (60/70) vs 66.7% (28/42), P=0.017]. (2) Among the 88 hospitals using the VTE risk assessment sheet, the utilization rate of the evaluation sheet recommended by the obstetric VTE guideline in specialized hospitals (78.6%, 22/28) was higher than that of general hospitals (48.3%, 29/60), and the difference was statistically significant ( P=0.007). (3) The proportion of VTE incidence in general hospital group was 0.126% (360/286 517), and the proportion of VTE incidence in specialized hospital group was 0.032% (154/484 111). Logistic regression analysis showed that the OR value of the specialized hospital group was 0.253 (95% CI: 0.209-0.305) and the difference was statistically significant ( P<0.01) compared with the general hospital group. After adjusting the hospital level, B-ultrasonography and CTPA accessibility, whether to establish a risk assessment and obstetric VTE system, the proportion of VTE incidence in specialized hospitals was still lower than that in general hospitals ( OR=0.307, 95% CI: 0.251-0.376, P<0.01). Conclusions:General hospitals have higher access to resources for diagnosing VTE than specialized hospitals, and the VTE evaluation system is better implemented. The utilization rate of the obstetric VTE guidelines in specialized hospitals is higher than that of general hospitals.

Objective To evaluate the feasibility of intra-utero fetal lamb surgical repair. Methods Six twin lambs underwent surgery intra-utero at 112 days of gestation (term 140～160 days). After maternal laparotomy and Hysterotomy, fetal lamb′s toe was excised or its cleft lip was repaired in one of twin. Results At 30 to 32 days post operation,five lambs were spontamcously delivered and the other was cesarean delivery to full term gestation. Fetal wounds healed without inflammation and scar formation. Conclusions The methods of fetal lamb intro utero surgical repair is feasible.

Objective To study the application effect of clinical pathway teaching in respiratory medicine. Methods Seventy clinical medical students of our department during 2007 to 2009 were randomly divided into two groups. The control group (35 students) was treated by traditional teaching ways, while the experimental group(35 students) was treated by clinical pathway teaching ways, with 5 to 6 students forming a small group. Teachers provided one copy of the CP version to each person in advance. Then progressive questions and discussions were conducted according to the diagnosis, dif-ferential diagnosis and treatment of CP. After its implementation for a certain time, students were co-mprehensively assessed by the practice examination and questionnaire and the statistical analysis was performed by using SPSS 17.0 version statistics software. Results The experimental group's total aver-age score was (90.00±4.00) points, while the control group's total average score was (76.00±7.20) points. There was significant difference between the two groups(P=0.001). The effect of these two kinds of teaching was evaluated and compared in stimulating interest in learning (P=0.002), improving the analytical ability(P=0.004),improving self-study ability(P=0.001), deepening the under-standing of the basic concepts(P=0.112), improving the innovation ability (P=0.005), improving the efficiency of learning(P=0.034), improving clinical comprehensive ability(P=0.016), and improving the ability of language expression(P=0.000), showing that teaching method of clinical pathway could significantly improve clinical teaching effect, and there was statistically significant difference between them. Conclusion Clinical pathway teaching has obvious advantages in cultivating students' diagnostic thinking and clin-ical ability to solve practical problems, and therefore it has better clinical teaching effect than the tra-ditional teaching method.

Objective:To investigate the efficiency of maternal serum triple screening for the genetic abnormality in second-trimester and the morbidity of adverse pregnancy outcome in false positive results of the test. Methods: A total of 4 680 pregnant women with singleton pregnancies assigned in Obs & Gyn Hospital, Fudan University, underwent triple screening test (alpha fetoprotein, AFP; human chorionic gonadotropin, HCG and unconjugated estriol, uE3) by fluorescence enzyme immunoassay between 2003 and 2005. The valid MoM (Multiples of Median) value of mid-trimester serum AFP, uE3, and hCG and risk assessments was provided by Beckman Coulter Co. When applied in the prenatal Down syndrome screening service. The study compares the incidence of chromosomal abnormalities with Down syndrome in screen positive women and compares to the MoM value established in the literature. The risks of having a fetus with congenital abnormalities or of developing obstetric complications in the screen positive women with their matched controls.Results:The MoM values for the triple tests of our study are similar to established values of literature. Only 51.01% women with pregnancies agree to receive screening. Amniocentesis utilization rate was 55.12% in the screen-positive pregnancies. The false positive rate was 6.89% and the median of maternal age of the women was 28.13 (range 19 to 49) years old. Chromosomal abnormalities were identified in 21 pregnancies, including 9 cases of trisomy 21.The detection rate was 77.77%. Pregnancies with positive screening results had a significantly higher risk of adverse outcomes than those with negative results (P< 0.05). Whereas there was no difference in the incidences of fetal congenital appearance or skeleton abnormality. Conclusion: Adjusting MoM values of local unaffected populations is limited to increasing the detection rate. Because chromosomal defects have variable exhibitions, amniocentesis utilization is still a choice for screen-positive pregnancies. Screen-positive pregnancies had increased risk of chromosomal abnormalities.

Objective To compare the difference of protein and lipid metabolism between patients with inflammatory bowel disease and healthy controls,and to investigate the association of these changes with disease activity and location of the lessions.Methods The retrospective cohort study was carried out.The data of protein and lipid metabolisms collected from 195 patients with ulcerative colitis,76patients with Crohn's disease and 97 healthy controls during 1995 to 2007 were analyzed.Disease activity were evaluated using simple clinieal colitis activity index and simple index of Crohn's disease activity.The erythrocyte sedimentation rate(ESR)and C-reactive protein(CRP)were measured.Results Serum levels of ESR in patients with ulcerative colitis were negatively linear correlated with serum levels of albumin/globulin ratio(β=-0.521,P＜0.01)and positively linear correlated with serum levels of α2globulin(β=0.319,P＜0.01).Serum levels of globulin in patients with Crohn's disease were positively linear correlated with serum levels of ESR(β=0.558,P＜0.01)and CRP(β=0.424,P=0.01).In ulcerative colitis,serum levels of albumin/globulin ratio,albumin and total cholesterol were significantly higher in patients with proctosigmoiditis than those in patients with lesions at other locus(P=0.003,0.005,0.038,respectively).In Crohn's disease,serum level of globulin was significantly higher in patients with lesions only at colon than that in patients with lesions only at small bowel(P=0.029).Conclusions Serum levels of albumin/globulin ratio and α2-globulin can be predictors of inflammatory activity in patients with ulcerative colitis.The increasing serum globulin may predict the progression of disease activity in patients with Crohn's disease.The nutritional deficiency is more critical in patiens with small bowel involvement than those with colon involvement.

Objective To analyze the percentage and functional changes of natural killer T (NKT) cells in peripheral blood and bone marrow of severe aplastic anemia (SAA) children before immunosuppressive therapy (IST) comparing to that of healthy children.Methods Ten children with severe aplastic anemia were included in the study and ten healthy children at the same age were selected as the control group. By lfow cytometry, the percentage of CD3+CD1d tetramer+ NKT cell in peripheral blood and bone marrow were detected from March 2014 to December 2014 in our hospital. Immune magnetic bead separation was used to isolate and purify iNKT cells .The puriifed iNKT cells were cultured in the OCH(50 ng/ml,100 ng/ml or 200 ng/ml)+rhIL-2+rhG-CSF culture systems. The ampliifcation of iNKT cells after cultured in different systems were calculated. Elispot method was used to analyze the spotting form cells (SFCs) of IFN-γ or IL-4 expressed by activated iNKT cells.Results The percentage of CD3+CD1d tetramer+ NKT cells in peripheral blood of SAA group(0.72±0.03)% was signiifcantly lower than that of the control group(0.92±0.02)%(P=0.000). The percentage of CD3+CD1d tetramer+ NKT cells in bone marrow of SAA group(0.82±0.02)% was signiifcantly lower than that of the control group(1.05±0.05)%(P=0.000).In vitro iNKT cell ampliif-cation ability of bone marrow in SAA group was signiifcantly lower than the control group, and in medium concentration(50±6) and high concentration OCH group(52±6), the ampliifcation ability was higher than that in low concentration OCH group(30±5) (P<0.05). The secretion of IFN-γ in the iNKT cells of SAA bone marrow was signiifcantly lower in medium concentration(33±3) and high concentration(35±3)OCH group than that of the low concentration(50±3)OCH group(P<0.01). The secretion of IL-4 in the iNKT cells of SAA bone marrow was signiifcantly higher in medium concentration(50±3)and high concentration(75±3) OCH group than that of the low concentration(33±3) OCH group(P<0.01).Conclusions The quantity and function of NKT cells from children with SAA are lower than that of the healthy children.In vitro, they had better ampliifcation ability and could improve IL-4/IFN-γ imbalance in medium concentration and high concentration OCH group than in low concentration OCH group.
