Medical Journal of Chinese People's Liberation Army 2019;44(11):931-935
Objective To investigate the pregnancy outcome of patients with preeclampsia (PE). Methods The data of 26 206 pregnant and lying-in women were retrospective analyzed who gave birth in Daping Hospital of the Army Medical University from Jan. 1, 2013 to Apr. 30, 2019, diagnosed with the 8th and 9th version of gynecology and obstetrics textbook. Excluding 62 cases of diabetes combined pregnancy, 445 cases of hypothyroidism combined pregnancy, 180 cases of polyhydramnios, 1592 cases of macrosomia (≥4 kg), 89 cases of chronic hypertension with PE, and 629 cases of multifetation. The remaining 23 209 cases, according to the final diagnosis, were divided into PE group (532 cases) which was divided again into mild-PE group (134 cases) and severe-PE groups (398 cases), and the 22 677 remainders acted as the control group. The age, gestational weeks, number of births, mode of delivery, pregnancy complications and neonatal status in the three groups were compared, and the thyroid function among the groups was analyzed in detail. Results The proportion of elderly parturients was higher in both mild-PE group (29.2%) and severe-PE groups (20.6%) than that in control group (12.4%). The rates of premature delivery and cesarean section were higher in both mild-PE group (19.7% and 55.0%) and severe-PE groups (70.1% and 94.2%) than those in control group (10.0% and 48.2%). The incidences of hypothyroidism during pregnancy, intrahepatic cholestasis of pregnancy (ICP) and infants younger than gestational age were higher in both mild-PE group (26.9%, 10.5% and 7.5%) and severe-PE groups (23.9%, 9.3% and 22.1%) than those in control group (17.5%, 3.5% and 2.9%); The incidences of placental abruption and stillborn foetus were obviously higher in severe-PE group (3.8% and 7.3%) than those in control group (0.6% and 0.7%). The incidence of gestational diabetes was significantly higher in mild-PE group (41.8%) than that in control group (30.0%), and of umbilical cord around neck was significantly lower in severe-PE group (17.6%) than that in control group (25.1%). Conclusions The incidences of complications and therapeutic premature delivery in PE patients is increased. Hypothyroidism during pregnancy is a potential risk factor and should be strenuously supervised.

Objective To analyze the differential expression of proteome between metastatic lymph nodes and normal lymph nodes in esophageal squamous cell carcinoma.Methods Two dimensional polyacrylamide gel electrophoresis(2-DE)technique and computer-assisted image analysis were used to separate the protein spots and analyze the differential expression of proteome in the metastatic lymph nodes and normal lymph nodes.Results There were 23 protein spots significantly differentially expressed,of which 4 protein spots were newly found,1 protein spot disappeared,14 protein spots increased markedly,and 4 protein spots decreased significantly.Conclusion The proteomic expression in metastatic lymph nodes of esophageal squamous cell carcinoma is significantly different from that of the normal lymph nodes,which may be associated with the mechanism of metastasis of esophageal squamous cell carcinoma.

Objective To explore the application of particle-gun technique in transfecting dendritic cells(DCs),and investigate the expression of DNA vaccine particle IgHV1-GM-CSF in DCs induced by particle-gun.Methods Monocytes were isolated from donor peripheral blood collected by Ficoll density gradient method and adherent culture,and then differentiated into immature DCs(imDCs) by rhGM-CSF and rhlL-4 induction.The plasmids for transfection were IgHV1-GM-CSF/pcDNA3.0 and pEGFP,which were prepared with endofree plasmid purification kit.The DCs were transfected with plasmid pEGFP by particle-gun at different transfection conditions,the green fluorescence positive cell and the total cell numbers were counted respectively under fluorescence microscope,and the transfection efficiency was calculated;the viable cell count was performed after trypan blue staining;the transfection efficiencies of particle-gun,liposome-mediated transfection and electroporation method were compared.The plasmids IgHV1-GM-CSF/pcDNA3.0 and pEGFP were cotransfected into imDCs by particle-gun under the optimum conditions,and then DNA was extracted,the expression of IgHV1-GM-CSF was determined by RT-PCR,and of GM-CSF by ELISA.Results The optimum conditions of particle-gun transfection in imDCs were: gas pressure at 120psi,PVP concentration in 0.02mg/ml,microcarrier loading in 0.5mg gold/shot,and DNA loading ratio in 1.5?g plasmid/mg gold.The transfection efficiencies of particle-gun and electroporation were 10.5%?2.4%(n=3) and 45.2%?5.6%(n=3) respectively,while that of liposome-mediated transfection was very low,and significant difference existed among the three methods(P

AIM: To investigate the protective effects of ulinastatin on the rats with paraquat-induced acute lung injury and its mechanisms .METHODS:The Wistar rats ( n=108 ) were randomly divided into control group , pa-raquat group and ulinastatin group .The rats in paraquat group and ulinastatin group were given paraquat by gavage , while the rats in control group were given sterile saline by gavage .The rats in ulinastatin group were also given ulinastatin treat-ment.The serum levels of MDA, SOD, IL-6, IL-10 and TNF-αwere measured after 1 d, 3 d, 7 d, 14 d, 21 d and 28 d. The expression levels of p 38 MAPK, MMP-2 and TIMP-1 in the lung were also measured .RESULTS:The levels of SOD in 1 d, 3 d and 7 d in paraquat group and ulinastatin group were significantly lower than those in control group ( P<0.01).The level of SOD in ulinastatin group was significantly higher than that in paraquat group (P<0.05).The levels of MDA, IL-6, IL-10 and TNF-αin 1 d, 3 d and 7 d in paraquat group and ulinastatin group increased compared with con-trol group (P<0.01), and those in ulinastatin group were significantly lower than those in paraquat group (P<0.05). The levels of p38 MAPK and TIMP-1 in 1 d, 3 d, 7 d, 14 d, 21 d and 28 d in paraquat group and ulinastatin group were higher than those in control group (P<0.01), and those in ulinastatin group was significantly lower than those in paraquat group ( P<0.05) .The level of MMP-2 in 1 d, 3 d, 7 d, 14 d and 21 d in paraquat group and ulinastatin group increased compared with control group (P<0.01), and that in ulinastatin group was significantly lower than that in paraquat group (P<0.05).CONCLUSION:Ulinastatin protects the lung tissues of rats from paraquat-induced acute lung injury by in-hibiting p38 MAPK signaling pathway and ameliorating inflammatory and oxidative responses .

Objective To study the neuroprotective effects of erythropoietin on intracerebral hemorrhage (ICH). Method The rat models of 1CH were produced by injecting autologous blood into caudate necleus by using stereotatic techique. One hundred ten male wistar rats were randomly divided into 4 groups, namely normal group,sham operation group, 1CU group, and EPO treatment group. The immunohistochemistry and TUNEL were used to detect expressions of Bc 1-2 and Bax,and apoptosis cells. LSD- t and Pearson correlation were used to analyzing data. Results The positive cells of TUNEL Bcl-2 and Bax in ICH group and EPO group obviously increased over 6 hours,and reached peak 72 hours later,and decreased over 120 hours,and the positive cells in different intervals significantly decreased in ICH group and EPO group compared with those in sham operation group (P < 0.01). The positive cells of TUNEL and Bax in EPO group in different intervals significantly decreased compared with those in ICH group (P < 0.01). The Bcl-2 positive cells in EPO group in different intervals significantly increased compared with those in ICH group (P < 0.01). The Bax protein expression, Bax/Bcl-2 and apoptosis presented positive correlation (P < 0.01). Conclusions Apoptosis may induce some brain injury after ICH,and EPO can decrease the number of apoptotic cells after ICH by up-regulating Bcl-2 and down-regulating Bax.

Objective · To estimate correlation between coronary artery calcification score (CaCS) and prognosis of peritoneal dialysis (PD) patients.Methods · The clinically stable patients who had undergone PD for at least 2 months were recruited for this prospective and observational cohort study.Coronary artery calcification was assessed by multislice spiral computed tomography and was recorded according to the Agatston score. The patients were assigned to 3 groups, i.e. no calcification group (CaCS=0), low calcification group (0
