Objective To understand the clinical features, management, pregnant outcomes and prognosis of pregnant women complicated with systemic lupus erythematosus (SLE). Methods Retrospective analysis of 34 women (35 pregnancies) complicated with SLE were conducted and 26 of them were followed up for 0.5～15 years. Results (1) Out of the 35 pregnancies in these 34 women, 8 were in remission stage, 8 in the well-controlled period, 1 in active phase and 18 were primary onset (10 diagnosed during the pregnancy, and 8 after terminations) during the pregnancy. (2) Among those diagnosed during the pregnancy, 2 women in the remission group and 3 in the well-controlled group were in the active stage of SLE. The several most common clinical manifestations indicating SLE deterioration were proteinuria, fatigue, edema, hypertension, erythra and decreased serum C3. (3) In women with onset during the pregnancy, 7 (38.9%) presented with proteinuria, edema and hypertension which similar to symptoms of gestational hypertension. (4) The average maternal age of the remission group was much older than those women with onset during pregnancy [(32.4±5.5) years vs (26.6±3.9) years, P=0.034]. while the proportion of active lupus nephritis was lower than that of the later (1/4 vs 16/16, P=0.004) and the well-controlled group (1/4 vs 6/6,P=0.033) during post-partum follow-ups. Conclusions Pregnancy prompted lupus nephritis has nothing to do with maternal age, but the stage of SLE. Patients who conceived in the remission stage are the least likely to have nephritic damage. Although women with onset during the pregnancy is relatively young, they are expected to have more serious renal damage and poor prognosis.

Objective To investigate the feasibility and effectiveness of ‘ group-head responsibility teaching method' in the physiology experiment teaching.Methods Totally 422 students of clinical medicine major in 2010 grade were randomly divided into two groups:212 students in control and 210 in study group.For students in control group,principles,procedures,items of experiment and computer operation were first taught,then experiment was performed while for those in study group,initial procedures were firstly explained,then the group heads were called together to observe the experiment preformed by teacher,after that the group heads returned to assist other students performing the experiment.Finally,experiment success rates,scores of final-term experiment operation,theoretical exam and report of two groups were compared and analyzed.Meanwhile,questionnaire survey was conducted.Results Success rates were improved significantly in study group than in control group (x2 =37.42,P =0.0000).There were significant differences in operation scores (t =4.3213,P =0.0000),theoretical exam scores (t =6.8744,P =0.0000) and report scores (t =15.298,P =0.0000) between the two groups.Conclusions ‘ Group-head responsibility teaching method' is better than traditional lecture-style teaching method and it can promote comprehensive capabilities of students.

Objective To evaluate the effects of B-Lynch suture for postpartum hemorrhage due to uterine atony,and to clarify its influence on long-term fertility and next pregnancy outcome.Methods We retrospectively collected the medical records of 150 women who underwent B-Lynch suture during cesarean section due to intra-operative bleeding caused by uterine atony from January 1,2006 to December 31,2013 in Peking University First Hospital.Follow-up was carried out to assess postoperative menstruation and subsequent pregnancy outcomes.Results All the cases underwent B-Lynch suture which successfully retained the uterus.Satisfactory hemostasis was achieved in 131 women (87.3％) who underwent B-Lynch suture only,and in eighteen women (12.0％) who had bilateral uterine artery ascending branch ligation at the same time;and in one patient (0.7％) who underwent B-Lynch suture and uterine artery embolization four hours later due to poor uterine contraction.Of the 141 (94.0％) cases followed up after surgery,menstrual cycle was assessed in a total of 104 women:no changes in the menstrual cycle and bleeding volume were noted in 67 cases (64.4％),prolonged menstruation was observed in five cases (4.8％),menorrhagia in ten cases (9.6％),and hypomenorrhea in 22 cases (21.2％).Eleven women (23.9％) became pregnant and delivered in two to four years after the surgery,and all were full-term abdominal delivery.Conclusions B-Lynch suture is a simple,safe,and effective treatment for postpartum hemorrhage due to uterine atony,without significant change of menstruation.B-Lynch suture is not associated with infertility,and the postoperative pregnant outcome is good.

Objective To explore the relationship between maternal pre-pregnancy body mass index (BMI) and neonatal birth weight in women with gestational diabetes mellitus (GDM). Methods From the pregnant women who received prenatal care and delivered at the Department of Obstetrics and Gynecology of Peking University First Hospital between May 1, 2012 and November 1, 2013, 550 GDM women aged 20-49 years and with single gestation were enrolled in this study. According to the pre-pregnancy BMI, the GDM women were divided into overweight group (BMI ≥ 24.0, n=145) and non-overweight group (BMI < 24.0, n=405). Gestational weight gain, glucose level of 75 g oral glucose tolerance test, glucose control, delivery mode and neonatal birth weight were compared between the two groups. The influencing factors for macrosomia and the relationship between maternal pre-pregnancy BMI and neonatal birth weight were analyzed. Independent sample t-test, Chi-square test, multivariate Logistic regression and Pearson correlation analysis were used for statistical analysis. Receiver operating characteristic (ROC) curve was used to determine the optimal threshold of pre-pregnancy BMI to predict macrosomia. Results Compared with the data of non-overweight group, fasting glucose level [(5.1±0.5) vs (5.3±0.5) mmol/L, t=-4.599], 1 h glucose level [(9.4±1.7) vs (9.8±1.6) mmol/L, t= - 2.742], proportion of poor glucose control [20.5% (83/405) vs 33.1% (48/145), χ2=8.281], proportion of cesarean delivery [37.8% (153/405) vs 55.2% (80/145), χ2=13.160], neonatal birth weight [(3 306±424) vs (3 476±545) g, t=-3.374], and ratio of macrosomia [5.4% (22/405) vs 16.6% (24/145), χ2=16.291] were all higher in overweight group (all P < 0.01). The mean gestational weight gain per week in overweight group was significantly lower than in non-overweight group [(336±123) vs (402±131) g, t=5.136, P < 0.01]. Pre-pregnancy overweight (OR=4.009, 95%CI:2.039-7.881), gestational weight gain per week (OR=1.003, 95%CI:1.001-1.005) and fasting glucose level (OR=2.285, 95%CI: 1.326-3.938) were the influencing factors for macrosomia (all P < 0.01). Pre-pregnancy BMI of GDM women was positively related with neonatal birth weight (r=0.179, P < 0.01). Pre-pregnancy BMI ≥ 22.8 was defined as the optimal threshold to predict macrosomia (ROC area under curve=0.691). Conclusions Maternal pre-pregnancy overweight is a significant risk factor for macrosomia in women with GDM. GDM women with pre-pregnancy overweight should control glucose level and weight gain during pregnancy in order to reduce the risk of macrosomia.

Objective To explore the relevance between fasting plasma glucose (FPG) level in early pregnancy and gestational diabetes mellitus (GDM). Methods Clinical data of 5299 singletonpregnant women accepted antenatal examination and delivered in the Department of Obstetrics and Gynecology, Peking University First Hospital from January 1, 2008 to December 31, 2009 were retrospectively analyzed. Results (1) The pregnant women were divided into 3 groups according to their FPG levels at early stage of gestation: Group A, FPG ＜5. 1 mmol/L (n= 4565); Group B,FPG≥5.1, but ＜5.8 mmol/L (n=701); Group C, FPG≥5.8 mmol/L, but ＜7.0 mmol/L(n=33). The incidence of GDM in Group A, B and C was 10. 69% (488/4565), 26. 11% (183/701)and 54. 55% (18/33). (2) The incidences of large for gestational age (LGA), cesarean section,premature birth, preeclampsia, neonatal hyperbilirubinemia, neonatal hypoglycemia, neonatal polycythemia, and neonatal infection were compared between Group A and B. The cesarean section rate [54. 63% (282/518)]and neonatal hypoglycemia rate [1.54% (8/518)]of those who were not diagnosed as GDM in middle and late term in Group B were higher than those of Group A [49.03%(1999/4077) and 0. 61% (25/4077)] (P＜0. 05); while there were no differences between the other six index of Group A and Group B (P＞0. 05). The prognosis of the GDM patients who did not accept gestational glucose management in two groups were similar (P＞0. 05), so did the prognosis of the GDM patients who accepted gestational glucose management in two groups. After combining the patients of the two groups who were not diagnosed as GDM as a new group, they were compared with those who did not accept gestational glucose management of the two groups (Group A2 and B2)respectively. The incidence of LGA rate of the new group was lower than that of Group A2 (12. 00%va 4. 94 %, x2=21. 4159, P＜0. 05) and Group B2 (18. 39 % vs 4. 94%, x2 = 28. 7189, P＜0. 05).Cesarean section rate of the new group was lower than that of Group A2 (57. 78% vs 49.64%,x2 =5. 6806,P＜0.05) and Group B2 (66. 67% vs 49.64%, x2 =9. 9003, P＜0. 05). And there were no differences between the other six index between the new group and the other two groups (P＞0. 05). Conclusions The diagnosis criteria of GDM set as FPG≥5.1 mmol/L at early stage of gestation, recommended by International Association of Diabetes and Pregnancy Study Group, is not applicable in China yet. Oral glucose tolerance test in middle and late term is still the most important diagnostic tool for GDM.

Objective To investigate the association between polymorphism of HLA-DRB1 allele and systemic sclerosis (SSc) and scleroderma-associated renal damage in Han Chinese of Henan Province.Methods Eighty-one SSc patients and 90 normal controls were recruited in this study,among them 59 patients had renal damage (SRD).The genotyping was carried out by nest PCR-SBT and gene clone.Comparisons between groups were performed with x2 test or exact probabilities.Multivariable Logistic regression was used to evaluate the association between prevalence of SSc or SRD and the possible relevant alleles.Results Thirty-three HLA-DRB1 alleles were discovered from the specimens,including 27 in SSc specimens,and 22 in SRD.Among them,the allele frequencies of HLA-DRB1 * 040501 (8.64％), * 110101 (11.11％), * 150201(8.02％) were higher in SSc patients than those of the controls (1.67％,4.44％,2.22％ respectively).After adjusted for other factors,HLA-DRBl * 040501 (P=0.010,OR =5.839,95％CI:1.518-22.460)、* 110101(P=0.019,OR=3.060,95％CI:1.204-7.772)、* 150201(P=0.010,OR=4.780,95％CI:1.444-15.821 )were identified as independent risk factors for SSc.And the allele frequencies of HLA-DRB1*040501 (9.32％),* 150201 (7.63％) were higher in SRD patients than those of the controls (1.67％,2.22％ respectively).After adjusted for other factors,HLA-DRB1 * 040501 (P=0.008,OR=6.363,95％CI:1.614-25.087) and * 150201 (P=0.030,OR =4.043,95 ％CI:1.147-14.243 ) were identified as independent risk factors for SRD.Conclusion Our data suggest that HLA-DRB1 * 040501,* 110101,* 150201 may be susceptible genes for SSc and the HLA-DRB1 * 040501,* 150201 may be susceptible genes for SRD in Han Chinese of Henan Province.

Objective To detect the serum level of mannose binding lectin (MBL) in patients with renal injury induced by rheumatoid arthritis (RA), and to investigate the role of MBL in the pathogenesis of renal injury in RA. Methods ELISA was used to measure the serum MBL level of 19 RA patients with renal injury, 49 RA patients without renal injury and 40 healthy individuals. The clinical features and laboratory markers were compared and analyzed by chi-square test, two independent samples t-test and Spearman's correlation analysis. Results Compared with RA patients without renal injury, the number of tender and swollen joints [(15±9) vs (9±11)], duration of morning stiffness [(2.9±1.3) vs (2.3±1.6) h] and extraarticular manifestations (42.1％ vs 16.3％) in RA patients with renal injury were significantly higher (P＜0.05or P＜0.01). There was no significant difference between the two groups in RA disease duration and jointdeformity(P＞0.05). In patients with renal injury, the level of platelet count [(376±155)×109/L vs (304±121)×109/L], CIC[(4.3±3.0) vs (2.9±3.3) g/L], ESR[(79±46) vs (53±31) mm/1 h], RF[(77±42) vs (52±49)U/ml], CRP[(32±28)vs (23±18)mg/L], IgG[(11.7±2.6)vs (8.4±2.4)g/L], C3[(1.18±0.53)vs (0.94±0.21) g/L] were higher than those in RA patients without renal injury (P＜0.01 or P＜0.05); the level of Alb [(26±13) vs (30±9) g/L] was lower than that in RA patients without renal injury (P＜0.05). The level of serum MBL in the two groups of RA patients was significantly lower than that in the healthy group [(3.1±0.5)mg/L](P＜0.01), and the level of serum MBL in RA patients with renal injury [(1.7±1.2) mg/L] was higher than that in RA patients without renal injury [(1.4±1.3) mg/L](P＜0.05). The level of serum MBL in RA patients with renal injury showed a positive correlation with IgG, C3, CRP and 24 h urine protein level (r=0.6, 0.6, 0.47, 0.57; P＜0.05). Conclusion Renal injury in RA patients is immune complex dependent. The serum level of MBL is higher in patients with renal injury, therefore, high-concentration MBL may be one of a potential causes of renal injury in RA patients.

Objective To elaborate the glucose and lipid metabolism 1 year postpartum on the foundation of postpartum 6-12 weeks in patients with prior gestational abnormal glucose metabolism in Beijing area.Methods Seventy-three patients who delivered during February to December,2007,aged (32.0 ± 3.6) years,were enrolled.46 cases (63％) were diagnosed as cases of gestational diabetes mellitus (GDM) while 27 (37％) as gestational impaired glucose tolerance (GIGT).All of the patients were revisited twice by 6-12 weeks and 1 year postparaum.Body weight,waist andhip circumferences,oral glucose tolerance test(OGTT),and lipids profile were determined.Results Compared with 6-12 weeks postpartum,the body weight,waist and hip circumferences,and waist-to-hip ratio were decreased by 1 year postpartum,fasting plasma glucose was increased [(5.19 ± 0.06) vs (4.84 ± 0.57) mmol/L,P＜0.01],and 4 cases were diagnosed as cases with impaired fasting glucose (IFG; 4 vs 0).By 6-12 weeks and 1 year postpartum,postprandial plasma glucose levels were (6.84± 1.93) and (7.33 ± 1.50) mmol/L(P=0.017),and the incidences of impaired glucose tolerance(IGT) were 28.8％ and 38.4％ (P=0.167),respectively,with 6 cases of newly diagnosed IGT by 1 year postpartum.There were more cases of hypertriglyceridenia (19.2％ vs 13.7％),less cases of hypercholesterolemia(19.7％ vs 30.0％,P＜0.01),more cases with improved high-densit.y lipoprotein-cholesterol (21.9％ vs 4.1％,P＜0.01),and less cases with raised low-density lipoproteincholesterol(21.9％ vs 49.3％,P＜0.01).No difference was found in body weight,body mass index,waist circumference,hip circumference,and waist-to-hip ratio between GIGT and GDM groups.Conclusion GDM is an important cause of the increasing prevalence of diabetes in women of reproductive age.Although body weight and waist-to-hip ratio have been improved,they would still develop glucose intolerance and dyslipidemia 1 year postpartum.

Objective To investigate the therapeutic effect of uteroplasty aided with temporary balloon occlusion of abdominal aorta in treating pernicious placenta previa combined with placenta percreta.Methods Sixty-two third-trimester gravidas who were diagnosed as pernicious placenta previa combined with placenta percreta by prenatal ultrasound and magnetic resonance imaging (MRI) in the First Affiliated Hospital of Zhengzhou University from January 1,2013 to May 31,2016 were enrolled in this study.All of them received cesarean section and then underwent uteroplasty following temporary balloon occlusion of abdominal aorta.Efficacy of that treatment was evaluated from the perspectives of blood loss,operation time,complications and postoperative recovery.All data were analyzed by descriptive analysis.Results All of the 62 cases were diagnosed with placenta percreta during operation including 10 cases (16.1％) with perimetrium invasion,46 cases (74.2％) with invasion to the muscular layer of bladder and six cases (9.7％) with bladder invasion.The average blood loss of all cases during and within 24 hours after operation was (1 377.3±605.2) ml and (140.6±66.3) ml,respectively.The average operation time was (72.3 ±24.5) min and the average length of postoperative hospital stay was (5.8± 1.6) d.The six cases of placenta percreta with bladder invasion received bladder repair.Sixty-one cases had their uterus preserved and the other one case had a sub-total hysterectomy due to amniotic fluid embolism.One woman developed phlebothrombosis in her lower limbs after operation.No intestinal or ureteral injury,puerperal infection,uterine ischemia necrosis or death was reported.In addition to three cases lost to follow-up,the other 59 patients were followed up to May 31,2017.Results of physical examination indicated that the 59 cases had normal uterine involution after operation.Menses returned in 58 of the 59 cases without any difference from before,and did not return in one case due to breastfeeding.Conclusion Uteroplasty aided with temporary balloon occlusion of abdominal aorta is a safe and effective uterus-preserving surgery for patients with pernicious placenta previa combined with placenta percreta.

Objective To investigate the value of qualitative and quantitative parameters of MRI on diagnosis of benign and malig-nant breast lesions.Methods Patients were scanned with MRI who were confirmed as breast lesions verified by histopathology,and the time-signal curve(TIC),Slopemax ,the apparent diffusion coefficient values (ADC)were deduced.Results There were 24 benign and 11 malignant lesions.Features of benign lesions were shown as follow:The TIC type wasⅠmostly 91.7%,Slopemax was 0.65 %/s,the ADC values was 1.31×10 -3 mm2/s.Features of malignant lesions were shown as follow:The TIC type were Ⅱ and Ⅲ mostly (100%), Slopemax was 1.63 %/s,the ADC values was 1.06 ×10 -3 mm2/s.Conclusion Types of TIC,Slopemax ,the ADC values of MRI are valuable in the diagnosis of benign and malignant breast lesions,integrated functional parameters are better than an individual param-eters in that they can improve the accuracy of diagnosis.
