Objective To investigate the effects of normal-high blood pressure and Grade 1 hypertension during early pregnancy on preeclampsia(PE)and adverse pregnancy outcomes in pregnant women.Methods A retrospective cohort study was conducted,enrolling 2,562 postpartum women who delivered at the Shiyan Maternal and Child Health Hospital from March 2020 to November 2023 as study participants.Prenatal examination data and delivery medical records were collected for analysis.Women were categorized into three groups based on blood pressure measurements taken before 20 weeks of gestation:normal blood pressure(n=2 029):systolic blood pressure<120 mmHg and diastolic blood pressure<80 mmHg;normal high blood pressure(n=375):systolic blood pressure 120～139 mmHg or diastolic blood pressure 80～89 mmHg;and Level 1 hypertension(n=158):systolic blood pressure 140～159 mmHg or diastolic blood pressure 90～99 mmHg.The incidence rates of PE and adverse pregnancy outcomes(including cesarean section,placental abruption,spontaneous preterm delivery[before 37 weeks],postpartum hemorrhage,stillbirth after 20 weeks of gestation,Apgar score<7,neonatal admission to the NICU,small for gestational age,macrosomia,and neonatal death within 28 days of birth)were compared and analyzed across the three groups.Cox regression analysis was performed to investigate the impact of early pregnancy blood pressure levels on the risk of PE and adverse pregnancy outcomes.Results(1)Women with normal high blood pressure had a 2.163-fold increased risk of PE compared to women with normal blood pressure(95%CI:1.228～3.809,P=0.007).However,there were no statistically significant differences in the rates of cesarean section(OR=1.341,95%CI:0.528～3.405,P=0.537),placental abruption(OR=1.016,95%CI:0.925～1.115,P=0.740),Apgar score<7(OR=1.422,95%CI:0.976～2.071,P=0.066),spontaneous preterm birth(OR=1.027,95%CI:0.925～1.140,P=0.617),postpartum bleeding(OR=1.141,95%CI:0.873～1.491,P=0.334),stillbirth after 20 weeks of gestation(OR=1.276,95%CI:0.980～1.661,P=0.070),neonatal admission to NICU(OR=1.301,95%CI:0.674～2.511,P=0.432),small for gestational age(OR=1.089,95%CI:0.927～1.279,P=0.299),macrosomia(OR=1.336,95%CI:0.824～2.166,P=0.240),or neonatal death within 28 days of birth(OR=1.275,95%CI:0.918～1.770,P=0.147).(2)Compared to women with normal blood pressure,women with grade 1 hypertension had a significantly higher risk of preeclampsia(OR=3.829,95%CI:1.749～8.385,P<0.001),cesarean section(OR=2.414,95%CI:1.298～4.489,P=0.005),and placental abruption(OR=2.537,95%CI:1.196～5.384,P=0.015).Additionally,they had a higher rate of Apgar score<7(OR=1.829,95%CI:1.069～3.130,P=0.027).No statistically significant differences were observed for spontaneous preterm birth(OR=1.404,95%CI:0.713～2.764,P=0.326),postpartum bleeding(OR=1.236,95%CI:0.845～1.807,P=0.274),stillbirth after 20 weeks of gestation(OR=1.076,95%CI:0.902～1.283,P=0.415),neonatal admission to NICU(OR=1.346,95%CI:0.873～2.075,P=0.178),small for gestational age(OR=1.417,95%CI:0.926～2.168,P=0.108),macrosomia(OR=1.235,95%CI:0.629～2.424,P=0.539),or neonatal death within 28 days of birth(OR=1.275,95%CI:0.918～1.770,P=0.147).(3)ROC analysis shows that when the sample combination was normal high blood pressure(n=375),the predictive/evaluative efficacy AUC of early pregnancy blood pressure values(threshold 139/89)for PE was 0.757.When the sample combination was level 1 hypertension(n=158),the predictive/evaluative efficacy AUC of early pregnancy blood pressure values(threshold 159/99)for four adverse outcomes,including PE,cesarean section,placental abruption,and Asperger's score<7,were 0.789,0.717,0.709,and 0.742,respectively.Conclusion Compared with pregnant and parturient women with normal blood pressure,having a normal high blood pressure or grade 1 hypertension before 20 weeks of pregnancy will significantly increase the risk of PE;in addition,grade 1 hypertension is also associated with a higher incidence of adverse pregnancy outcomes,including cesarean section,placental abruption,and low Apgar score of the newborn.

Objective To study the relationship and prognosis between E-cadherin gene expression and lymphatic hyperplastic reaction in gastric cancer. Methods The degree of lymphocytosis and draining lymph node from 86 cases of gastric cancer were observed and the expression of E-cadherin gene in gastric cancer were detected by SP method of immunohistochemistry (IHC). Results Lymphocyte infiltration degree around gastric cancers was positively related to the reactive hyperplasia of the lymphnodes and was inversely related to lymphatic metastasis. The expression of E-cadherin has relationship with the infiltration degree of stomach carcinoma. To compare with T1/T2 and T3/T4 phases, the result is significantly different (P ＜0.01).Meanwhile, the expression of E-cadherin was positively correlated with tumor-infiltrated lymphocytes and reactive hyperplasia of the lymph nodes, was negatively correlated with lymphatic metastasis in drainage area.Conclusion The over-expression of E-cadherin gene is significantly related to lymphoproliferation and lymph node metastasis. The abnormal expression of E-cadherin can be used as an index to determine prognosis of gastric carcinoma.

Objective To investigate the prevalence,their autoantigen and the clinical significants of antiendothelial cell antibodies(AECAs) in systemic vasculitis.Methods Western blotting was performed to detect specific AECA in serum of systemic vasculitis,SLE,RA,SS and healthy donors.Then to analyze the relationships of AECA with the disease manifestation.Results(1)The prevalence of AECA was 77.7% in systemic vasculitis,87.5% in SLE,66.7% in SS,7.14% in RA and 10% in normal group respectively.(2)AECA reacted with a heterogeneous series of endothelial proteins which ranged in molecular size from 16 to 120 ku Furthermore,AECA against a 47 ku endothelial cell antigen were more frequently found in a variety of systemic vasculitis and SLE.(3)Compared with those in AECA-negative patients,the mean levels of ESR in AECA-positive patients with TA and the mean levels of BVAS in patients with WG,MPA and CSS were both significantly higher in AECA-positive patients.Patients with BD who have AECA against 47 ku endothelial cell proteins were more frequently found to have neuropathy than those 47 ku-AECA-negative patients,and the prevalence of inhanced CRP are also more frequent.Conclusion AECA showed to be correlated with the disease manifestation,and the same molecular sizeantigen could be found in a variety of systemic vasculitis and SLE.

Abstract:Objective To investigate the effect of intrathecal injection (IT) with methotrexate (MTX) plus dexamethasone (DXM) in treating central nervous system involvement in systemic lupus erythematosus (CNS lupus). Methods Twenty-four CNS lupus patients that were refractory to conventional steroid therapy were selected for IT with MTX 10-20?mg plus DXM 10-20?mg. The effects and side effects of IT were closely observed. Results The symptoms and signs of 22/24 (91.7%) CNS lupus patients receiving IT improved considerably. Cerebrospinal fluid pressure,protein and WBC levels declined from 201.5±155.4?mm?H2O, 145.2±87.6?mg/dl and 25.1±14.3/mm3 to 128.7±108.1?mm?H2O, 60.8±38.3?mg/dl and 6.8±2.1/mm3 respectively. Transient side effects were observed in 4 patients: 1 with itching sensation of lower limbs, 2 with headache and 1 with incontinence.Conclusion IT with MTX plus DXM is a promising method for treating CNS lupus and deserves further investigation.
