RESUMEN
Objective:To investigate and analyze disease status and risk factors of venous thromboembolism (VTE) during pregnancy and puerperium in our country.Methods:Clinical datas were collected from 575 patients diagnosed with VTE during pregnancy and puerperium and hospitalized in nine medical institutions in our country from January 1, 2015 to November 30, 2019, and retrospectively analyzed it′s disease status and risk factors.Results:(1) The proportion of VTE in pregnancy and puerperium was 50.6% (291/575) and 49.4% (284/575), respectively. Four patients died, the mortality rate was 0.7% (4/575). The cause of death was pulmonary embolism. (2) The location of VTE during pregnancy and puerperium was mainly in the lower limb vascular (76.2%, 438/575), followed by pulmonary vessels (7.1%, 41/575). (3) In the risk factors of VTE, cesarean section accounted for 32.3% (186/575), maternal advance age accounted for 27.7% (159/575), braking or hospitalization during pregnancy accounted for 13.6% (78/575), other risk factors accounted for more than 5% were previous VTE, obesity, preterm birth, assistant reproductive technology conception and so on, pre-eclampsia and multiple pregnancy accounted for 4.9% (28/575) respectively. In addition, some patients with VTE did not have any of the above risk factors, and the incidence rate was as high as 23.1% (133/575).Conclusions:The occurrence of VTE during pregnancy and puerperium is related to multiple risk factors, and could lead to matemal death, It is very necessary to screen VTE risk factors for all pregnant women, to make corresponding prevention and control measures.
RESUMEN
[Objective]To investigate the disturbance between Th17 and Treg cell balance in ovarian endometriosis patients.[Methods]Case-control study comparing 40 women with histo-pathologically confirmed ovarian endometriosis and with 40 control infertility women without visible endometriosis foci ,pelvic inflammations who were subjected to laparoscopic surgery during the same period. Peripheral blood,peritoneal fluid,ovarian ectopic endometrial tissue and eutopic endometrial tissue of ovarian endometriosis patients and controls were collected during surgery. T lymphocytes subpopulations in peripheral blood were analyzed by flow cytometry using specific monoclonal antibodies recognizing CD4+,CD25+and CD127-markers and CD3+,CD8-and IL-17A+markers. Then, IL-17,IL-22,IL-10and TGF-βconcentration in the serum and peritoneal fluid was determined using enzyme linked immunosorbent assay(ELISA). Also,Q-PCR was performed to verify Foxp3 mRNA and ROR-γt mRNA expression differences in eutopic and ectopic endometrial tissue.[Results]1.The percentage of CD4+CD25+CD127-Treg cells was significantly decreased in the peripheral blood ofwomen with ovarian endometriosis compared with control women. On the other hand ,the proportion of CD3+CD8-IL-17A+Th17 cells was significantly increased in the peripheral blood of women with endometriosis compared with control wom en. 2. Comparing with the controls ,the concentration of IL-17 and IL-22 was significantly higher in the serum of women with ovarian endometriosis ,and the levels of IL-10 and TGF-β were significantly lower in the serum of women with endometriosis. On the contrast ,in the peritoneal fluid of women with ovarian endometriosis ,the concentration of IL-17 and IL-22 were lower ,and the concentration of IL-10 and TGF-β were significantly higher than the controls. 3.Foxp3 mRNA expression level was significantly elevated in ectopic endometrial tissue of patients with ovarian endometriosis compared with eutopic endometrial tissue ,while the ROR-γt mRNA expression level of ectopic endometrial tissue was significantly decreased than eutopic endometrial tissue.[Conclusion]The present study verifies the imbalance of Th17/Treg in peripheral blood ,peritoneal fluid and endometrial tissue in ovarian endometriosis patients ,which implies the immune dysregulation and the disturbance of immunity homeostasis in the establishment and progression of endometriosis.
RESUMEN
[Objective]To investigate the influence of different pre-pregnancy body mass index(BMI)on blood glucose and serum lipid and pregnancy outcome during pregnancy.[Methods]Clinical records of 1115 singleton pregnant women who underwent obstetric examination and delivered in the first affiliated hospital of Sun Yat-sen University between January 1,2013 and December 31,2013 were collected. The patients were divided into 3 groups based on pre-pregnancy BMI,underweight(G1):BMI 0.05). By Pearson analysis,TG had significantly positive relationship with pre-pregnancy BMI(P < 0.05),but TC,LDL-C, HDL-C had negative relationship with pre-pregnancy BMI(P<0.05).(4)With the increase of pre-pregnancy BMI,the weight and head circumference of the newborn was gradually rising(P < 0.05). The average weight of the newborn among groups were(3.03 ± 0.42),(3.18 ± 0.45),(3.30 ± 0.46)kg,the head circumference were(32.98 ± 1.59),(33.43 ± 1.64),(33.87 ± 1.60)cm,there was statistical difference among groups(P<0.05). The shoulder circumference of the newborn of G1 was obviously lower than that of G2 and G3 group(P<0.05). Pearson analysis showed that the weight,body length,head circumference,shoulder circumference of the newborn had positive relationship with pre-pregnancy BMI(P < 0.05).[Conclusion]With the increase of pre-pregnancy BMI, the blood glucose at each time point,serum lipid and growth index of the newborn was gradually rising. We suggest that overweight and obese women should lose weight before pregnancy.
RESUMEN
Objective To determine the effects of adiponectin on high glucose induced BeWo cell proliferation in vitro. Methods BeWo cells were seeded in 96-well plates at the appropriate density. After treatments with high glucose (25 mmol/L), western blot analysis of cyclin D1 and a colorimetric assay (cell counting kit-8, CCK-8) were used to analyse BeWo cells′proliferation, and western blot was used to detect the expression of adiponectin. Moreover, we added adiponectin (20μg/ml) in the culture medium and three methods were utilized for cell proliferation analysis: CCK-8, cell cycle analysis (by flow cytometry) and proliferating cell nuclear antigen (PCNA) immunocytochemical staining. Results Compared to BeWo cells cultured by normal glucose and high mannitol, the proliferation of BeWo cells treated by high glucose increased (P<0.05). Compared with BeWo cells cultured by high mannitol, the expression of adiponectin in BeWo cells treated by high glucose decreased. After added adiponectin in the culture medium, the proliferation of BeWo cells treated by adiponectin+high glucose decreased than that of cells treated by high glucose (0.770±0.050 versus 0.990±0.070, P<0.05);the proportion of G2+S phases of BeWo cells treated by adiponectin+high glucose decreased than that of cells treated by high glucose [(40.7±2.1)%versus (44.9± 3.9)%, P<0.05];the rate of PCNA positive cell in BeWo cells treated by adiponectin+high glucose decreased than that of cells treated by high glucose [(28 ± 5)% versus (44 ± 5)%, P<0.05]. Conclusion Adiponectin could inhibit proliferation of high glucose induced BeWo cells in vitro.
