Methods: The data of maternal near miss in 5 hospitals of Hangzhou City from 2015 to 2020 were collected from China's National Maternal Near Miss Obstetrics Surveillance System, and the incidence and mortality of maternal near miss, types of pregnancy-related complications/comorbidities and types of critical illness were descriptively analyzed. Results: Totally 230 490 pregnant and lying-in women were recruited in 5 hospitals in Hangzhou City from 2015 to 2020, and there were 182 514 live births, 177 428 women with pregnancy-related complications/comorbidities, and 1 790 cases of maternal near miss with a 0.98% annual incidence rate. The incidence of maternal near miss was high in 2019 (1.18%). The hospital mortality and death index were respectively 3.29/105 and 0.33% among pregnant and lying-in women from 2015 to 2020, and there was no death found among pregnant and lying-in women from 2018 to 2020. The main pregnancy-related complications/comorbidities included anemia (79.33%), obstetric hemorrhagic disorders (69.83%), and gestational hypertension (16.65%). The main critical illness among maternal near miss included coagulation dysfunction (87.23/104), cardiovascular dysfunction (20.44/104), and respiratory dysfunction (9.70/104). Conclusions The incidence of maternal near miss was high and the hospital mortality appeared a reduction tendency among pregnant and lying-in women in Hangzhou City from 2015 to 2020. Coagulation dysfunction is the primary critical illness among maternal near miss, and the management of anemia and hemorrhagic diseases requires to be improved.

One hundred patients were diagnosed with coronary heart disease through dual-source CT coronary angiography (DSCTA) in our hospital,including 53 cases aged ≥60 y (elderly group) and 47 cases ＜60 y (middle-aged group).The curved-planar reconstruction (CPR),maximal intensity projection (MIP) and other post-processing reconstruction techniques were used to evaluate the indicators and differences of coronary stenosis ≥ 50％ ; the X-ray coronary angiography (CAG) findings were regarded as the gold standard.The evaluable rates of coronary arteries through DSCTA were 97.0％ and 98.6％ for two groups (P ＞0.05).The positive rate of coronary artery stenosis ≥ 50％ in elderly group was higher than that of middle-age group ( 12.6％ vs 9.0％ P ＜0.05 ).The rates of multi-vessel disease in elderly group (28.3％ ) was also significantly higher than that of middle-age group (6.4％,P ＜0.05 ).The sensitivity,specificity,positive predictive value and negative predictive value in evaluation of coronary artery stenosis ≥ 50％ for elderly patients were 92.3％,98.0％,88.0％ and 98.9％ respectively; those for middle-aged patients were 96.0％,99.0％,90.6％ and 99.6％ respectively ( P ＞0.05 ).DSCTA imaging provides an effective screening and evaluation method for coronary heart disease in elderly and middle-aged patients.

Objective : To explore the influencing factors for maternal anemia during the third trimester of pregnancy, so as to provide the evidence for the effective prevention of anemia. Methods : Data of parturients, who received prenatal care and delivered at Hangzhou Women＇s Hospital from October to December of 2019 were retrospectively collected and analyzed. The obstetric electronic medical record system of this hospital was used to collect general information of the subjects. Serum ferritin, serum vitamin B12, serum folic acid and hemoglobin were determined at the second and third trimester. A multivariate logistic regression model was used to analyze the influencing factors for anemia in the third trimester. Results : A total of 1 143 parturients were enrolled, with a median age of 29 ( interquartile range: 4 ) years. Among them, 1 050 cases had normal weight before pregnancy, accounting for 91.86%; 267 cases were multiparas, accounting for 23.36%; 74 cases of anemia occurred during the third trimester of pregnancy, accounting for 6.92%.Multivariate logistic regression analysis indicated that the multipara（OR=1.714,95%CI: 1.032-2.848）, iron deficiency duiring the second trimester（OR=3.301,95%CI: 1.401-7.781）, iron deficiency during the third trimester （OR=14.134,95%CI: 1.944-102.774）and folate deficiency during the third trimester（OR=2.960,95%CI: 1.295-6.766）were influencing factors for anemia during the third trimester. Conclusion Anemia during the third trimester of pregnancy is related to iron deficiency during the second and third trimesters, folic acid deficiency during the third trimester, and multipara.

OBJECTIVE To investigate DNA hypermethylation of human 8-hydroxyguanine glycosy-lase(hOGG1 )gene and and the level of oxidative stress and DNA oxidative damage relations with arse-nic poisoning.METHODS In ende mic coal-pollution-borne arsenism area,Xinren county,Guizhou Province,according to the diagnostic criteria of ende mic arsenism(WS /T21 1 -2001 ),207 people with ende mic arsenism were selected and divided into four groups(The arsenic exposure group:46 cases, mild arsenism group:46 cases,moderate arsenism group:60 cases and severe arsenism group:55 cases).64 residents were selected as controls in a village about 12 km away fro m the ende mic arsenism area.With the informed consent principle,peripheral blood of all respondents was collected in order to analyze DNA methylation.Methylation-specific poly merase chain reaction were respectively performed to analyze hOGG1 Hypermethylation in arsenism respondents.Che mical methods were performed on the activity of super oxide dis mutase (SOD)and glutathione peroxidase (GSH-Px),while the contents of malondialdehyde (MDA)in the blood of patients were measured,and the contents of 8-hydroxy-2′-deox-yguanine(8-OHdG)urine of patients were measured and analysed.On the basis of methylation status are divided into hOGG1 gene methylation group (34 cases)and hOGG1 gene no methylation group (237cases).Analysis was performd on hOGG1 gene DNA methylation and the relationship between oxi-dative stress and arsenic poisoning.RESULTS The positive rates of hypermethylation of hOGG1 were associated with the degree of arsenic poisonin (co mpared with control group,χ2 =23.916,P <0.05, Co mpared with the Ende mic area normal group,χ2 =12.039,P <0.05 ).Co mparing with negative group,SOD〔(85 ±25)kU·L -1 〕,GSH-Px〔(70 ±26)kU·L -1 〕activity and 8-OHdG 〔(22.5 ±6.8)μg·L -1 〕contents were lower〔(1 18 ±41 )kU·L -1 ,(171 ±56)kU·L -1 ,(28.4 ±6.5)μg·L -1 ,P <0.05)〕in positive group.There was no significant difference between the MDA content(P>0.05).CONCLUSION Coal arsenic exposure can cause hOGG1 gene high methylation and oxidation and anti-oxidation system imbalance,causing DNA oxidative damage,it is one of the reasons to pro mote the develop ment of arsenic poisoning occurred.
