ABSTRACT
Objective:To investigate the difference of urinary protein components in pregnant women with pre-eclampsia (PE) with different degrees of proteinuria and the correlation between 24-hour urinary protein quantification and estimated glomerular filtration rate (eGFR).Methods:Clinical data of 101 PE pregnant women who were delivered in Renji Hospital, Shanghai Jiao Tong University School of Medicine from July 2018 to June 2022 were retrospectively analyzed. According to 24-hour urinary protein quantification, they were divided into 3 groups, including 40 cases of mild proteinuria group (24-hour urinary protein quantification ≤2.0 g), 21 cases of moderate proteinuria group (2.0 g<24-hour urinary protein quantification ≤5.0 g), 40 cases of severe proteinuria group (24-hour urinary protein quantification >5.0 g). The general clinical data, urinary protein index and renal function index of PE pregnant women in 3 groups were compared. The eGFR was calculated based on age, serum creatinine (sCr), blood urea nitrogen (BUN) and serum albumin (sAlb). Correlation analysis was conducted between 24-hour urinary protein quantification and each index of eGFR.Results:(1) General clinical data: the median PE onset week (31 weeks) and delivery gestational week [(36.4±3.6) weeks] of PE pregnant women in the mild proteinuria group were later than those in the moderate proteinuria group [median PE onset: 22 weeks, delivery: (32.2±4.2) weeks] and severe proteinuria group [median PE onset: 25 weeks, delivery: (29.6±3.4) weeks]; systolic blood pressure, diastolic blood pressure, alanine aminotransferase, aspartate aminotransferase levels and the incidence of fetal growth restriction were lower than those in the moderate and severe proteinuria groups; median newborn birth weight (3 150 g) was higher than those in the moderate proteinuria group (1 305 g) and the severe proteinuria group (1 042 g), respectively. The differences were statistically significant (all P<0.05). (2) Urinary protein index: the 24-hour urinary protein quantification, urinary microalbumin (mAlb) and urinary transferrin (TRF) levels of PE pregnant women in the mild proteinuria group, moderate proteinuria group and severe proteinuria group were increased successively, and the differences were statistically significant (all P<0.05). The median urinary α1-microglobulin (α1-MG) level of PE pregnant women in the severe proteinuria group (50 mg/L) was significantly higher than those in the mild proteinuria group (17 mg/L) and moderate proteinuria group (22 mg/L; all P<0.05), but there was no significant difference between the mild proteinuria group and the moderate proteinuria group ( P>0.05). There was no significant difference in the median urinary β2-microglobulin (β2-MG) level among the 3 groups ( P=0.632). (3) Renal function index: sAlb and eGFR of PE pregnant women in the mild proteinuria group, moderate proteinuria group and severe proteinuria group were successively decreased, and BUN was successively increased, respectively, and the differences were statistically significant (all P<0.05). The sCr level of PE pregnant women in the severe proteinuria group was significantly higher than those in the mild proteinuria group and the moderate proteinuria group (all P<0.05), but there was no significant difference between the mild proteinuria group and the moderate proteinuria group ( P>0.05). (4) Correlation analysis: the 24-hour urinary protein quantification of PE pregnant women was significantly negatively correlated with eGFR ( r=-0.645, P<0.001), and was correlated with the variables sAlb ( r=-0.549, P<0.001), sCr ( r=0.582, P<0.001) and BUN ( r=-0.657, P<0.001) in the eGFR calculation formula. The 24-hour urinary protein quantification were significantly negatively correlated with the gestational weeks of PE onset, gestational weeks of termination of pregnancy and newborn birth weight (all P<0.05). Conclusions:The protein composition in the urine of PE pregnant women with different degrees of proteinuria is not different, but the protein level is significantly different. There is a significant negative correlation between the increase of 24-hour urinary protein quantification and the decrease of eGFR.
ABSTRACT
To explore the correlation of mid-term oral glucose tolerance test (OGTT) and maternal weight gain with adverse pregnancy outcomes in women with gestational diabetes mellitus (GDM). A total of 2611 pregnant women with GDM who were examined and delivered in Women's Hospital, Zhejiang University School of Medicine from July 1st 2017 to 30th June 2018 were enrolled in this study. According to the number of abnormal items of mid-term OGTT results or maternal gestational weight gain (GWG), patients were classified. The incidence of adverse perinatal outcomes in each group and its relation with OGTT results and GWG were analyzed. The incidence of gestational hypertension, premature delivery, macrosomia and large for gestational age infant (LGA) in three abnormal items GDM patients were significantly higher than those in one or two abnormal items GDM patients (all <0.017). The incidence of gestational hypertension and premature delivery in two abnormal items GDM patients were higher than those in one abnormal item GDM patients (all <0.017). The incidence of gestational hypertension and macrosomia in excessive GWG patients were significantly higher than those in inadequate and appropriate GWG patients (all <0.017), and the incidence of LGA were higher than that in inadequate GWG patients (all <0.017). The incidence of premature delivery and low birth weight infants in appropriate GWG patients were significantly lower than those in inadequate and excessive GWG patients, and the incidence of small for gestational age infant (SGA) were significantly lower than that in inadequate GWG patients (all <0.017). In one abnormal item GDM patients, inadequate GWG was a risk factor for premature delivery and SGA (=1.66, 95%: 1.10-2.52; =2.20, 95%: 1.07-4.53), and protective factor for LGA (=0.40, 95%: 0.27-0.59). And excessive GWG was a risk factor for gestational hypertension, premature delivery and low birth weight infants (=2.15, 95%: 1.35-3.41; =1.80, 95%: 1.20-2.72; =2.18, 95%: 1.10-4.30).In two abnormal items GDM patients, inadequate GWG was a protective factor for macrosomia and LGA (=0.24, 95%: 0.09-0.67; =0.54, 95%: 0.34-0.86), while excessive GWG was risk factor for premature delivery (=1.98, 95%: 1.23-3.18).In three abnormal items GDM patients, there was no significant relationship between GWG and adverse pregnancy outcomes. For GDM women with one or two items of elevated blood glucose in OGTT, reasonable weight management during pregnancy can reduce the occurrence of adverse pregnancy outcomes. For those with three items of elevated blood glucose in OGTT, more strict blood glucose monitoring and active intervention measures should be taken in addition to weight management during pregnancy.

Objective To analyze risk factors, cardiovascular complications, time of death, gestational age of delivery and offspring outcomes in the maternal deaths with cardiovascular diseases (CVD). Methods Totally 4 112 cases of pregnant women with CVD in Shanghai obstetric heart disease intensive care unit within 26 years (from January 1993 to December 2018) were collected, and 20 maternal deaths within these cases were analyzed retrospectively. Results (1) Among the 20 deaths, structural heart diseases accounted for 90% (18/20), pregnancy induced heart diseases was 10% (2/20) while there was no dysfunctional heart disease. The mortality of pregnant women with CVD was 0.486% (20/4 112). (2) The following risk factors were common in these women, getting pregnant without counselling (95%, 19/20), New York Heart Association classⅢorⅣcardiac function (70%, 14/20), complicated with pulmonary hypertension (75%, 15/20 ) and prior heart events (60%, 12/20). And 85% (17/20) deaths occurred in puerperium, 15% (3/20) occurred before labor , while no death occurred during labor. And 65% (13/20) deaths died due to heart failure, 20% (4/20) deaths were due to pulmonary hypertension crisis, 5% (1/20) died on sudden cardiac arrest, rupture of aortic dissection and sudden death, respectively. Conclusions Women with CVD should get pregnant after strict evaluation. Pulmonary hypertension is one of the most severe contraindications to pregnancy, especially in patients with moderate to severe pulmonary hypertension. The puerperium period is a critical period that threatens the safety of these patients. Since heart failure is the most common cause of death, it is necessary to prevent and treat heart failure and to monitor heart function dynamically, especially in those with structural abnormal heart diseases. Moreover, it is also of importance to standardize antenatal care and to identify the severity of heart diseases in time.

ABSTRACT
Objective To observe and analyze the difference of serum immunoglobulin IgA, IgG, IgM, β2-microglobulin and transferrin in pre-eclampsia (PE) and pregnancies complicated with chronic kidney disease.Methods Totally 46(40.0%)pregnancies with PE(PE group),36(31.3%)pregnancies with chronic kidney disease(chronic kidney disease group)and 33(28.7%)normal pregnancies with normal blood pressure and proteinuria without any complication(control group)delivered in Renji Hospital were recruicted in this study from February 2017 to July 2017.Serum IgA,IgG,IgM,β2-microglobulin and transferrin levels were detected. Correlation tests were conducted between these indicators and blood pressure, 24 hours proteinuria value and delivery weeks. Results (1) Comparison of general situation of pregnancies in the 3 groups:there were no significant difference in the age and child bearing history between the 3 groups(all P>0.05),while there was a significant difference in the blood pressure and deliver week(all P<0.01).There was no significant difference in 24 hours proteinuria values between PE group and chronic kidney disease group (Z=-0.187, P=0.852). (2) Comparison of serum immunoglobulin, β2-microglobulin and transferrin levels in pregnant women with three groups: serum IgA level in chronic kidney disease group was significantly higher than those in PE and control groups[(2.4±0.9)vs(1.8±0.9)vs(1.6±0.6)g/L;F=9.959,P<0.01].The serum IgG and IgM values had no significant difference between the 3 groups(all P>0.05).Serum β2-microglobulin in chronic kidney disease group was significantly higher than those in PE and control groups[(4.0±2.6)vs(2.7±0.7)vs(2.0±0.5)mg/L;F=15.892,P<0.01].Serum transferrin in chronic kidney disease group was significantly lower than those in PE and control groups[(3.0±0.8)vs(3.7±1.1)vs(3.6±0.6) g/L; F=6.284, P<0.01]. (3) The correlation between serum immunoglobulin, β2-microglobulin, transferrin and blood pressure, proteinuria value and delivery weeks in PE group: the blood pressure level was not correlated with serum IgA,β2-microglobulin and transferrin values in PE group(all P>0.05).So,24 hours proteinuria value was positively correlated with β2-microglobulin (r=0.557, P<0.01), which was negatively correlated with transferrin (r=-0.442, P<0.01) and was not correlated with IgA(r=0.089, P=0.556). There was a negative correlation between delivery weeks and β2-microglobulin(r=-0.328,P=0.026),and positive correlation with transferrin (r=0.315, P=0.035) and no correlation with IgA (r=-0.169, P=0.260). (4) The correlation between serum immunoglobulin, β2-microglobulin, transferrin and blood pressure, proteinuria value and delivery weeks in chronic kidney disease group:the blood pressure level was positively correlated with β2-microglobulin(systolic pressure: r=0.598,P<0.01;diastolic pressure:r=0.557,P<0.01),which was not correlated with IgA and transferrin in chronic kidney disease group (all P>0.05). So,24 hours proteinuria value was positively correlated with β2-microglobulin and IgA(r=0.568,r=0.330,both P<0.05), and not correlated with transferrin (r=0.255, P=0.133). Delivery weeks had a negative correlation with β2-microglobulin(r=-0.574,P<0.01),while it had a positive correlation with transferrin(r=0.369,P=0.027). No correlation was found between delivery weeks and IgA values (r=-0.257, P=0.131). Conclusion The serum levels of IgA,β2-microglobulin and transferrin in PE and pregnancies with chronic kidney disease are significantly different,which may provide clinical value for the diagnosis of PE and pregnancies with chronic kidney disease in future.
ABSTRACT
Non-alcoholic fatty liver disease (NAFLD) refers to a wide spectrum of liver diseases ran ging from simple fatty liver(SFL) to non-alcoholic steatohepatitis(NASH),which in turn can evolve into cirrhosis and end stage of liver disease.With the improvement of living standards,the number of obese children gradually has increased,the detection rate of NAFLD also has showed an growing trend.However,the pathogenesis is still unclear.Auxiliary examinations include biochemical tests,imaging studies and liver biopsy,the last one is the "golden standard" of the diagnosis.The treatments of NAFLD consists of dietary intervention and lifestyle changes,even medical therapies.At present,the awareness of children NAFLD is imperfect,its diagnosis and treatment remain to be further exDlored.
ABSTRACT
Objective To investigate relationship between the variation degree of platelet mitochondria in rats with severe hemorrhagic shock and the degree of shock.Methods Thirty-six Wistar rats were divided into sham group,shock 30,60,and 120 minutes groups,shock 120 minutes + normal saline (NS) + blood reinfusion group (NS group) and shock 120 minutes + polydatin (PD) + blood reinfusion group (PD group) according to random number table,with six rats per group.Content of ATP in platelets was detected by fluorescein-luciferase assay kit; structure of platelet mitochondria by electron microscope; state of mitochondrial permeability transition pore by Calcein-AM and CoCl2 ; change of mitochondrial membrane potential (△Ψm) by JC-1 mitochondrial membrane potential kit; lipid hydroperoxide (LPO) in platelets by LPO assay kit; stability of platelet lysosomes by acridine orange (AO).Results ATP released from platelets was reduced significantly in shock 60 minutes group (P ＜0.01) and with the prolong of shock period,further reduction was observed,particularly in NS group [(50.75 ± 9.15)％ of normal value].Mitochondrial swelling with poorly defined crista structure,declined △Ψ and low lysosome stability (pale cells were increased) were observed in shock 30 minutes group.Calcein fluorescence in mitochondria was faded in shock 60 minutes group (P ＜ 0.01).Whereas in PD group,all the above indices presented some recovery with ATP level returned to nearly (79.57 ± 8.48) ％ of normal value in particular.Conclusions Platelet mitochondrial dysfunction takes place at 30-60 minutes following severe shock.Hence,it may be served as an non-invasive index for the diagnose and treatment of severe shock.
