ObjectiveThrough qualitatively and quantitatively analysis of the differences in chemical composition between the combined decoction and single decoction of Huaganjian and comparison of their core efficacy， to explore the rationality of the flexible clinical application of Huaganjian compound preparations and single-flavored dispensing granules. MethodsUltra performance liquid chromatography-quadrupole-electrostatic field orbitrap high resolution mass spectrometry（UPLC-Q-Exactive Orbitrap MS） was used to qualitatively analyze the combined decoction and single decoction samples of Huaganjian， and meanwhile， the contents of four index components（geniposide， paeoniflorin， hesperidin and paeonol） were quantitatively analyzed by high performance liquid chromatography（HPLC）. Nonalcoholic fatty liver disease（NAFLD） rat model induced by high-fat diet was applied to compare the efficacy of combined decoction and single decoction of Huaganjian. A total of 30 male SD rats were randomly divided into the control group， model group， lovastatin group（1.8 mg·kg^-1）， combined decoction group（1.26 g·kg^-1） and single decoction group（1.18 g·kg^-1）. After successful modeling， lovastatin group， combined decoction group and single decoction group were given corresponding doses of drugs by intragastric administration every day， and the control group and model group were given equal amounts of normal saline by intragastric administration， after 4 weeks of administration， the serum and liver tissues were collected， and the contents of alanine aminotransferase（ALT）， aspartate aminotransferase（AST）， total cholesterol（TC）， triglyceride（TG）， low-density lipoprotein cholesterol（LDL-C） and high-density lipoprotein cholesterol（HDL-C） in serum of rats were detected， and the liver pathological examination was carried out by hematoxylin-eosin（HE） staining and oil red O staining， so as to compare differences of their efficacy. ResultsSeventy chemical components were initially identified and attributed from the lyophilized powder of the combined decoction and single decoction samples of Huaganjian， and there was no obvious difference in composition between the two. Further quantitative analysis showed that the contents of geniposide， paeoniflorin， hesperidin and paeonol in the combined decoction samples were significantly increased when compared with those of the single decoction samples（P<0.01）. The pharmacodynamic results showed that compared with the model group， both the combined and single decoction groups of Huaganjian could improve the liver index of NAFLD rats， reduce the serum levels of AST， ALT， TC， TG and LDL-C， increase the serum level of HDL-C， and ameliorate the pathological changes of liver cell steatosis and fat accumulation. However， there was no significant difference in pharmacodynamic effects between the combined decoction group and the single decoction group. ConclusionThere is no significant difference between the combined decoction and single decoction of Huaganjian in terms of chemical composition， but the contents of the four index components show significantly difference. Both of them can significantly improve the fat accumulation and liver function in NAFLD rats. This study provides a reference basis for the rational clinical application and evaluation of famous classical formula compound preparations and single-flavored dispensing granules.

Objective:To investigate the relationship between gestational weight gain (GWG) in twin pregnancies and adverse perinatal outcomes.Methods:This retrospective study included twin pregnant women with live births at≥25 weeks of gestation and their offspring, who delivered at Peking University People's Hospital from January 2012 to October 2022. Total GWG was standardized according to gestational age and categorized into three groups based on the 2009 Institute of Medicine (IOM) guidelines: insufficient GWG (GWG below IOM recommendations), appropriate GWG (GWG within IOM recommendations), and excessive GWG (GWG above IOM recommendations). Comparisons between data of the three groups used analysis of variance, Kruskal-Wallis test or Bonferroni correction or Chi-square partitions. Multivariable logistic regression models and generalized estimating equations with logistic regression models were used to analyze the independent effects of GWG on maternal and neonatal outcomes. Results:A total of 794 twin pregnant women and their 1 588 live-born neonates were included in the study. There were 360 women (45.3%) with appropriate GWG, 356 (44.8%) with insufficient GWG, and 78 (9.8%) with excessive GWG. Both insufficient and excessive GWG were associated with an increased risk of preterm birth [adjusted ORs of 1.39 (95% CI: 1.04-1.88) and 1.70 (95% CI: 1.05-2.78), respectively]. Insufficient GWG was associated with an increased risk of gestational diabetes mellitus (adjusted OR=1.42, 95% CI: 1.00-2.01) and low birth weight infants (adjusted OR=2.04, 95% CI: 1.57-2.66). Insufficient GWG was also associated with a reduced risk of eclampsia or preeclampsia (adjusted OR=0.50, 95% CI: 0.33-0.75), cesarean section (adjusted OR=0.48, 95% CI: 0.30-0.77), discordant twin growth (adjusted OR=0.56, 95% CI: 0.37-0.85), and large for gestational age infants (adjusted OR=0.46, 95% CI: 0.35-0.61). Excessive GWG was associated with an increased risk of eclampsia or preeclampsia (adjusted OR=2.85, 95% CI: 1.65-4.91), and large for gestational age infants (adjusted OR=2.49, 95% CI: 1.60-3.86), while with a decreased risk of low birth weight infants (adjusted OR=0.42, 95% CI: 0.27-0.65). Conclusions:More than half of the twin pregnancies have GWG outside the recommended range of the IOM guidelines. Both insufficient and excessive GWG are associated with adverse perinatal outcomes, particularly an increased risk of preterm birth.

Objective To explore the research hotspots on systemic lupus erythematosus(SLE)in pregnancy based on the bibliometric analysis of the related articles published from 2018 to 2023 and provide di-rections for the future research in this field.Methods PubMed,Web of Science,and Embase were searched for the articles on SLE in pregnancy that were published from January 1,2018 to December 31,2023.VOSviewer was used to visualize the high-frequency keywords in the selected articles.Results A total of 266 articles were selected,from which 25 high-frequency keywords were extracted.The bibliometric analysis showed that the available studies about SLE in pregnancy mainly focused on maternal complications,maternal and fetal outcomes,and medica-tions.The studies were limited regarding the predictors,autoimmunity,immunotherapy,and long-term outcomes of offspring.Conclusion Maternal complications,maternal and fetal outcomes,and medications are currently hotspots in the research on SLE in pregnancy,while predictors,autoimmunity,immunotherapy,and long-term outcomes of offspring may become future research directions.

Objective:To preliminarily explore the association of pregnancy factors with cow's milk protein allergy in infants.Methods:This study was based on data from a subcohort of a study called ge-netic susceptibility to cow's milk allergy in Chinese children,including infants born in Peking University People's Hospital between March 1,2020,and December 31,2020.The infants were divided into a cow's milk protein allergy(CMPA)group and a control group according to whether they had developed cow's milk protein allergy at the age of 1 year.We retrospectively collected the clinical data of infants and their mothers before and during pregnancy,and analyzed the association of multiple factors during pregnancy with cow's milk protein allergy in infants.Results:A total of 278 infants were enrolled in this study,including 52 infants with CMPA and 226 infants without CMPA.Among them,there were 143 boys and 135 girls.The proportion of male infants in the CMPA group(69.2％)was higher than that in the control group(47.3％),and the difference was statistically significant(P=0.004).There were no significant differences in the distribution of birth weight,gestational age at birth,low-birth-weight in-fants,premature,umbilical cord entangle neck,and neonatal asphyxia between the CMPA group and the control group(P＞0.05).The proportion of mothers complicated with autoimmune diseases,anemia or antibiotics exposure during pregnancy in the CMPA group was higher than that in the control group,and there were statistical differences between the two groups(P＜0.05).There was no significant difference in the distribution of other pregnancy complications between the two groups(P＞0.05),such as eclamp-sia/preeclampsia,chronic hypertension/gestational hypertension,diabetes/gestational diabetes,thyroid diseases,and so on.There was no significant difference in the overall distribution of some blood routine indexes during pregnancy between the CMPA group and the control group(P＞0.05).Multivariate Lo-gistic regression analysis showed that male infant,mothers complicated with autoimmune diseases or ane-mia,antibiotic exposure during pregnancy were independent risk factors for cow's milk protein allergy.Conclusion:Male infant,mothers complicated with autoimmune diseases or anemia,antibiotic exposure during pregnancy were independent risk factors for cow's milk protein allergy.

Objective:To analyze the maternal and neonatal outcomes of pregnant women with leukemia.Methods:This retrospective study analyzed the clinical data of singleton pregnant women with leukemia and their neonates at the Obstetrics Department of Peking University People's Hospital from June 2009 to May 2021. Statistical analysis was performed using a two-sample t-test, the Wilcoxon Mann-Whitney rank sum test, and the Chi-square test (or Fisher's exact test). Results:(1) Ninety-one pregnant women were enrolled in this study, accounting for 2.8‰ of all deliveries during the same period. Among them, there were 15 (16.5%) with acute lymphoblastic leukemia, 38 (41.8%) with acute myeloid leukemia, and 38 (41.8%) with chronic myelogenous leukemia. Twenty-nine of the 91 pregnancies (31.9%) were terminated in the second or third trimester, and 62 babies (68.1%) were born through spontaneous delivery or cesarean section. The 62 parturients were (30.1±5.0) years old, of whom two died of complications of leukemia within 7 d after delivery, and five were transferred to the intensive care unit after delivery. Of the 62 cases, 18 (29.0%) received a blood transfusion and 12 (19.3%) received chemotherapy during pregnancy. (2) The proportion of patients with unremitted leukemia during pregnancy or newly developed leukemia was higher in women with terminated pregnancy than in those who continued the pregnancy [96.6% (28/29) vs 54.8% (34/62), χ2=15.83, P<0.001]. (3) The gestational age of the 62 newborns was (37.7±2.7) weeks. Premature, low birth weight and small-for-gestational-age infants accounted for 29.0% (18/62), 25.8% (16/62), and 12.9% (8/62), respectively. Hyperbilirubinemia occurred in 10 neonates (16.1%) and hypoglycemia in two (3.2%). Perinatal anoxia and asphyxia were reported in 13 cases (21.0%). Appearance, organ malformations, or chromosomal abnormalities were found in four neonates (6.4%) whose mothers did not receive chemotherapy during pregnancy. Fifty-nine infants underwent routine blood tests within 3 d after birth. The results showed that the mean white blood cell count, hemoglobin concentration, and platelet count were (16.1±7.0)×10 9/L, (181.5±20.0) g/L and (266.2±63.7)×10 9/L, respectively, and no juvenile cells were detected in their peripheral blood samples. Twenty children were followed up to 4 years and 4 months (9 months to 10 years and 3 months). No abnormalities in physical or mental development, motor function, or hematological system were reported. Conclusions:Pregnancy complicated by leukemia is rare and dangerous, which requires an individualized management strategy besides therapy for leukemia. A good prognosis is still expected with appropriate treatment.

ObjectiveTo explore the effect and toxicity change rule of Aconiti Lateralis Radix Praeparata（ALRP） and Zingiberis Rhizoma（ZR） before and after compatibility， and to reveal the compatibility connotation of them. MethodSixty SD rats were randomly divided into blank group， blank-ALRP group， blank-ALRP-ZR group， model group， model-ALRP group and model-ALRP-ZR group， the latter three groups were injected with adriamycin via tail vein to establish the model of heart failure， and the former three groups were injected with the same amount of physiological saline via tail vein. The effects of ALRP single decoction and ALRP-ZR mixed decoction on biochemical indexes and myocardial histopathological morphology of normal rats and model rats were compared. Metabolomics analysis was performed on rat serum samples， principal component analysis（PCA） and orthogonal partial least squares-discriminant analysis（OPLS-DA） were used to screen the differential metabolites between groups， and the differential metabolic pathways were analyzed. Combined with network pharmacology technology， the metabolites and their associated targets and pathways related to enhancing anti-heart failure efficacy and reducing cardiotoxicity were screened before and after the compatibility of ALRP and ZR， the screened representative pathways were verified by Western blot. ResultCompared with the blank group， the model group showed significant increases in the contents of brain natriuretic peptide（BNP）， creatine kinase（CK）， lactate dehydrogenase（LDH） and cardiac troponin（cTn）-T（P<0.01）， the blank-ALRP group showed obvious increases in CK， LDH， and cTn-T contents（P<0.05， P<0.01）， while the normal-ALRP-ZR group showed a significant increase in CK content（P<0.01）. Compared with the blank-ALRP group， the blank-ALRP-ZR group showed a obvious decrease in LDH content（P<0.05）， and pathological sections showed that both decoctions could lead to myocardial histopathological damage in normal rats. Compared with the model group， the model-ALRP-ZR group showed obvious decreases in BNP， CK， LDH and cTn-T contents（P<0.05， P<0.01）， and the model-ALRP group showed obvious decreases in BNP， LDH and cTn-T contents（P<0.05， P<0.01）. Compared with the model-ALRP group， the model-ALRP-ZR group showed a significant decrease in CK content（P<0.01）， and both decoctions could improve the pathological morphology of myocardial tissue in the model rats. Metabolomics results showed that ALRP single decoction and ALRP-ZR mixed decoction could recover 422 and 459 metabolites in model rats， respectively. And the metabolic disruption of ALRP-ZR mixed decoction on normal rats was weaker than that of ALRP single decoction. The results of network pharmacological association analysis showed that in the aspect of ZR enhancing the anti-heart failure efficacy of ALRP， 3 metabolites such as deoxyuridylic acid were correlated to 56 metabolites， 82 targets and 13 pathways， including calcium signaling pathway， renin secretion， renin-angiotensin system， etc. In the aspect of ZR reducing the cardiotoxicity of ALRP， 3 metabolites such as tyrosol were associated with 24 metabolites， 55 targets and 14 pathways， including adrenergic signaling in cardiomyocytes and carbon metabolism and so on. Western blot results showed that the expression of angiotensin-converting enzyme（ACE）， angiotensin-converting enzyme 2（ACE2） and angiotensin Ⅱ（Ang Ⅱ） in myocardial tissues of rats from the model group was significantly elevated by comparing with the blank group（P<0.01）. Compared with the model group， the model-ALRP group and the model-ALRP-ZR group showed significantly decreased expression of ACE， ACE2 and Ang Ⅱ（P<0.01）. Compared with the model-ALRP group， the expression of ACE2 and AngⅡ was significantly decreased in the model-ALRP-ZR group. Compared with the blank group， the expression of extracellular signal regulated kinase（ERK）， protein kinase B（Akt） and cTn-I3 was significantly elevated in the blank-ALRP group and blank-ALRP-ZR group（P<0.01）. Compared with the blank-ALRP group， the blank-ALRP-ZR group showed decreased expression of ERK， Akt and cTn-I3， but there was no statistical significance. ConclusionTo a certain extent， the combination of ALRP and ZR shows synergistic relationship under pathological state， and attenuated effect of compatibility under normal physiological state， and the pharmacodynamic characteristics and compatibility relationship of ALRP and ZR are closely related to the physiological state.

Objective:To investigate the effect of oral glucocorticoid dose on maternal and infant outcomes in female patients with systemic lupus erythematosus(SLE), thus providing reference for clinical work.Methods:Clinical data of pregnant women with SLE admitted to Department of Obstetrics, Peking University People′s Hospital from July 2015 to June 2020 were retrospectively analyzed.According to the daily oral glucocorticoid dose during pregnancy(equivalent converted to Prednisone), pregnant women were divided into 2 groups: ≤7.5 mg group(67 cases) and >7.5 mg group(74 cases). The maternal and fetal outcomes of the 2 groups were analyzed by t-test or χ2 test or Fisher′ s exact probability method. Results:The neonatal birth weight, birth length, white blood cell count and platelet count in ≤7.5 mg group were significantly higher than those in >7.5 mg group[(2 990.69±532.20) g vs.(2 734.57±608.35) g, (48.97±2.34) cm vs.(47.43±3.38) cm, (17.69±6.16)×10 9/L vs.(15.11±6.00)×10 9/L, (276.92±74.51)×10 9/L vs.(240.05±69.29)×10 9/L], while the incidence of low birth weight and neonatal transfer rate were significantly lower(13.85% vs.30.43%, 12.31% vs.33.33%) ( t/ χ2=2.587, 3.068, 2.354, 2.841, 5.301, 8.321, all P<0.05). Meanwhile, the incidence of maternal complications like hypertension disorders in pregnancy and gestational diabetes mellitus in the ≤7.5 mg group were lower than those in the >7.5 mg group, but the incidence of anemia and postpartum hemorrhage increased, although no significant differences were detected (all P>0.05). Conclusions:The overall maternal and fetal outcomes of patients with SLE with oral Prednisone ≤7.5 mg/d were better those medicated >7.5 mg/d, but the incidence of anemia during pregnancy and postpartum hemorrhage was higher.An individual monitoring and treatment should be concerned to improve the maternal and infant outcomes.

Intracytoplasmic sperm injection (ICSI) is an important treatment option for male infertility at pre-sent.However, a few patients still suffer from repeated ICSI fertilization failure because their sperm is unable to activate oocytes.Artificial oocyte activation (AOA) technology can improve the fertilization rate, pregnancy rate, live birth rate, etc., but it remains unknown whether AOA has short- and long-term effect on offspring.In this article, recent literature about the effect of AOA technology on perinatal outcomes, genetics, physical development and neurological development of offspring was summarized.This paper aims to provide reference for reproductive medicine workers and pediatricians in clinical practice.

Hepatitis B, hepatitis C, and type 2 diabetes mellitus (T2DM) are serious public health issues worldwide. This article analyzes the association of hepatitis B and hepatitis C with T2DM. The analysis shows that on the one hand, both hepatitis B and hepatitis C promote the pathogenesis of T2DM, which involves viral infection inhibiting insulin signal transduction as well as glucose uptake and glycogen synthesis in insulin target cells; on the other hand, patients with T2DM are prone to hepatitis B and hepatitis C, which may be associated with multiple organ dysfunction caused by diabetes.

Objective:To investigate the effect of reproduction on maternal and infant outcomes in female patients with systemic lupus erythematosus (SLE).Methods:Clinical data of SLE patients complicated with pregnancy admitted in the Peking University People′s Hospital from July 2015 to December 2019 were analyzed retrospectively.According to the history of live birth, SLE patients complicated with pregnancy were divided into primiparity group (94 cases) and reproduction group (32 cases). Maternal and infant outcomes of the 2 groups were analyzed.Results:A total of 126 SLE patients complicated with pregnancy were included in the present study.The proportion of using immunosuppressants was significantly lower in reproduction group than that of primiparity group [3 cases (9.38%) vs.27 cases (28.72%)] ( χ2=4.927, P=0.026). Complications like lupus nephritis, thyroid disease and postpartum hemorrhage significantly increased in the reproduction group (all P<0.05), and the adverse neonatal outcomes like preterm infants, low birth weight infants and small for gestational age infants in the reproduction group were lower than those in primiparity group, but no significant differences were detected(all P>0.05). There were no significant diffe-rences in the results of the first blood routine examination of newborns and the incidence of neonatal pathological jaundice between the 2 groups (all P>0.05). Conclusions:For SLE patients complicated with reproductive pregnancy, although the incidence of some pregnancy complications increases, the incidence of adverse neonatal outcomes decreases.In addition, reducing the use of immunosuppressants may have positive implications on neonatal outcomes.
