Objective To investigate safety and efficacy of dinoprostone suppositories(0.8 mm) used in cervical ripening and labor induction in women with term premature rupture of the membranes.Methods One hundred women of term monocyesis with premature rupture of the membranes,head presentation,bishop score less than 6(test group)and 180 women with intact fetal membranes(control group)were enrolled into this multicenter,prospective clinical study.The vaginal delivery system was inserted into the posterior foruix,and the patients were recumbent for 2 hours after insertion.The interval time from using dinoprostone suppositories to uterine contraction,to labor and delivery were recorded.The following index were also recorded and compared,including the mean inserted time of dinoprostone suppositories,fetal heart beat,meconium stained amniotic fluid,hyperstimulation of uterus and the other complications,mode of delivery,stage of labor,postpartum hemorrhage,status of neonates.Results Three cases intest group and 23 casesin control group weren't in labor within 24 hours.The rate of labor within 24 hours in test group was significant higher than that in control group(97.0% vs.87.2%,P<0.01).It was observed that 73 cases undergoing vaginal deliveries(75.3%,73/97)and 24 cases undergoing cesarean section dehveries(24.7%,24/97)in test group and 107 cases undergoing vaginal delivery(68.2%,107/157)and 50 cases undergoing cesarean section delivery(31.8%,50/157)in control group,when compared the rate of vaginal or cesarean section deliveries between two group,it didn't reach statistical difference (P >0. 05). It had no significant difference in the interval time from using dinoprostone suppositories to labor starting and the mean inserted time and the total labor time between two groups ( P > 0.05 ). The incidence of uterine tachysystole was 11.3% (11/97) in test group and 19. 1% (30/157) in control group (P>0. 05), which did not reach statistical difference (P>0. 05). There wasn't neonatal asphyxia in both groups. Conclusion It was safe and efficient to use dinoprostone suppositories for cervical ripening and induction of term pregnancy with premature rupture of the membranes, however, monitoring should be intensified.

Objective To explore the effect of Yangxueqingnao granule in treatment of cerebral small vessel disease (SVD)patients with mild cognitive dysfunction (MCI).Methods 52 patients with SVD related MCI were selected.They were treated with Yangxueqingnao granule,each 4.0 g,3 times a day,3 months for a course of treat-ment.Montreal cognitive scale (MoCA),simple mental state scale (MMSE)and event related potential (P300)were detected before and after treatment,and the clinical effect was observed.Results After a course of treatment by Yan-gxueqingnao granule,the cognitive function and memory of 52 patients were improved to some extent.In addition to the attention of an MoCA meter to a foreign project[Visual space:before taking the medicine (2.92 ±0.26)points,after taking the medicine (3.25 ±0.66)points;Named:before taking the medicine (2.26 ±0.70)points,after taking the medicine(2.92 ±0.49)points;Language:before taking the medicine (1.47 ±0.70)points,after taking the medicine (2.17 ±0.98)points;Abstraction:before taking the medicine (0.45 ±0.38)points,after taking the medicine (0.68 ±0.63)points;Delayed recall:before taking the medicine (1.67 ±0.74)points,after taking the medicine (2.52 ±1.50)points;Directional:before taking the medicine (4.73 ±0.35 )points,after taking the medicine (5.52 ±0.57)points ]and total score[Before taking the medicine (18.75 ±0.66)points,after taking the medicine (19.12 ±1.45)points],the differences were statistically significant (the total score:t =7.56,P =0.000;Visual space:t =5.86,P =0.002;Named:t =5.42,P =0.000;Be careful:t =1.23,P =0.121;Language:t =4.52,P =0.000;Abstraction:t =2.65,P =0.001;Delayed memory:t =7.96,P =0.000).While the total score of MMSE scale [before taking the medicine (25.36 ±1.89)points,after taking the medicine (28.53 ±2.91 )points],memory [before taking the medicine (2.64 ±0.42)points,after taking the medicine (2.75 ±0.53)points]and recall [before taking the medicine (1.52 ±0.48)points,after taking the medicine (1.98 ±0.78)points ],the differences were statistically significant(the total score:t =2.78,Memory:t =1.95,Recall:t =3.43,all P <0.05).P300 before and after treatment[before taking the medicine P300 latency of (389 ±21)ms,after taking the medicine P300 latency of (341 ±18)ms)],the difference was significant (t =12.514,P <0.001).Conclusion Yangxueqingnao granule had therapeutic effect in patients with SVD -MCI.

Objective To investigate the morbidity, diagnostic profile and perinatal outcome of pregestational diabetes mellitus (PGDM) in 15 hospitals in Guangdong province. Methods A total of 41338 women delivered in the 15 hospitals during the 6 months,195 women with PGDM(PGDM group) and 195 women with normal glucose test result(control group)were recruited from these tertiary hospitals in Guangdong province from January 2016 to June 2016. The morbidity and diagnostic profile of PGDM were analyzed. The complications during pregnancy and perinatal outcomes were compared between the two groups. In the PGDM group, pregnancy outcomes were analyzed in women who used insulin treatment (n=91) and women who did not (n=104). Results (1)The incidence of PGDM was 0.472%(195/41338). Diabetes mellitus were diagnosed in 59 women (30.3%, 59/195) before pregnancy, and 136 women (69.7%,136/195) were diagnosed as PGDM after conceptions. Forty-six women (33.8%) were diagnosed by fasting glucose and glycohemoglobin (HbA1c) screening. (2) The maternal age, pre-pregnancy body mass index (BMI), prenatal BMI, percentage of family history of diabetes, incidence of macrosomia, concentration of low density lipoprotein were significantly higher in PGDM group than those in control group (all P<0.05). Women in PGDM group had significantly higher HbA1c concentration((6.3±1.3)% vs (5.2±0.4)%), fasting glucose [(6.3±2.3) vs (4.8±1.1) mmol/L], oral glucose tolerance test(OGTT)-1 h glucose((12.6±2.9) vs (7.1± 1.3) mmol/L)and OGTT-2 h glucose [(12.0±3.0) vs (6.4±1.0) mmol/L] than those in control group (P<0.01). (3)The morbidity of preterm births was significantly higher (11.3% vs 1.0%, P<0.01), and the gestational age at delivery in PGDM group was significantly smaller [(37.6±2.3) vs (39.2±1.2) weeks, P<0.01]. Cesarean delivery rate in the PGDM group (70.8% vs 29.7%) was significantly higher than the control group (P<0.01). There was significantly difference between PGDM group and control in the neonatal male/female ratio (98/97 vs 111/84, P=0.033). The neonatal birth weight in PGDM group was significantly higher((3159±700) vs (3451±423) g, P<0.01). And the incidence of neonatal hypoglycemia in the PGDM group was higher than the control group (7.7% vs 2.6%, P=0.036).(4)In the PGDM group, women who were treated with insulin had a smaller gestational age at delivery [(36.9±2.9) vs (37.9±2.5) weeks, P<0.01], and the neonates had a higher neonatal ICU(NICU)admission rate (24.2% vs 9.6% , P<0.01). Conclusions The morbidity of PGDM in the 15 hospitals in Guangdong province is 0.472%. The majority of PGDM was diagnosed during pregnancy; HbA1c and fasting glucose are reliable parameters for PGDM screening. Women with PGDM have obvious family history of diabetes and repeated pregnancy may accelerate the process of diabetes mellitus. Women with PGDM have higher risk for preterm delivery and neonatal hypoglycemia. Unsatisfied glucose control followed by insulin treatment may increase the need for NICU admission.

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.
