ABSTRACT
Objective To investigate the expression and clinical significance of macrophage colony stimulating factor ( M?CSF ) and tumor necrosis factor α ( TNF?α ) in placenta of early onset severe preeclampsia (PE)??Methods Immunohistochemical SP method was used to detect the expression of M?CSF and TNF?α in 77 cases paraffin specimens from Department of Pathology,First Affiliated Hospital of Henan University of Science and Technology from September 2015 to September 2017,including 35 cases of early?onset severe PE,42 cases of late?onset severe PE and 30 cases of normal pregnant women??Results (1)The positive expression rates of M?CSF in control group,late?onset severe PE group and early?onset severe PE group were 30%(9／30),61??90%(26／42),82??86%(29／35),respectively??The difference was statistically significant ( χ2 ＝ 18??90, P＜0??05)??The positive expression rates of early?onset severe PE group were significantly higher than those in control group (χ2＝18??59,P＜0??05),and the difference was statistically significant????The positive expression of early?onset severe PE group was higher than that of late?onset severe PE group,and the difference was statistically significant (χ2＝4??017,P＜0??05)??(2) The positive expression rates of TNF?α in control group,late?onset severe PE group and early?onset severe PE group were 33??33%(10／30),69??05%(29／42),91??43%(32／35),respectively??The difference was statistically significant (χ2＝30??21,P＜0??05)??The positive expression of TNF?α in early?onset severe PE group was significantly higher than that in control group (χ2＝21??37,P＜0??05),and the difference was statistically significant??The positive expression of M?CSF and TNF?a in early?onset severe PE group was higher than that in late?onset severe PE group,and the difference was statistically significant (χ2＝4??529,P＜0??05); (3) The expression of M?CSF and TNF?α was positively correlated in PE (r＝0??441,P＝0??000)??Conclusion Placental damage is higher in early?onset severe PE,and is related to the severity of the disease??The levels of M?CSF and TNF?alpha in placenta of PE patients may play a synergistic role in the occurrence and development of PE??
ABSTRACT
Objective To explore the clinical effect of single use or combination of dydrogesterone and progestin in treatment of threatened abortion caused by uteal phase defect.Methods Totally 186 patients with threatened abortion caused by uteal phase defect accepted in The First Affiliated Hospital of Henan from April 2015 to April 2016 were selected and randomly divided into groups A,B,and C with 62 cases in each group.Patients in group A were given dydrogesterone,those in group B were given progestin,and those in group C were given dydrogesterone combined with progestin.Then the clinical effect,expression of hormones,treatment outcome,and adverse reaction were observed and compared.Results The total effective rates of groups A and B were 72.58％ and 66.13％,respectively,which were obviously lower than 90.32％ of group C with statistically significance (P ＜0.05).The expression levels of P,E2,and hCG of three groups after treatment were higher than those before,those in group C were the highest among them (P ＜ 0.05).The successful treatment rates of groups A,B,and C were 83.87％,82.26％,and 95.16％,respectively,which had no great difference.Conclusion Combination use of dydrogesterone and progestin has better effective rate in treatment of threatened abortion caused by uteal phase defect compared to single use of these two drugs,which has good safety and worth of clinical application.
