| 1 | Risk of gestational diabetes recurrence and the development of type 2 diabetes among women with a history of gestational diabetes and risk factors: a study among 18 clinical centers in China显示文摘Background:Gestational diabetes mellitus(GDM)brings health issues for both mothers and offspring,and GDM prevention is as important as GDM management.It was shown that a history of GDM was significantly associated with a higher maternal risk for GDM recurrence.The incidence of GDM recurrence was unclear because of the incidence of second-child was low before 2016 in China.We aim to investigate the prevalence of GDM recurrence and its associated high-risk factors which may be useful for the prediction of GDM recurrence in China.Methods:A retrospective study was conducted which enrolled participants who underwent regular prenatal examination and delivered twice in the same hospital of 18 research centers.All participants were enrolled from January 2018 to October 2018,where they delivered the second baby during this period.A total of 6204 women were enrolled in this study,and 1002 women with a history of GDM were analyzed further.All participants enrolled in the study had an oral glucose tolerance test(OGTT)result at 24 to 28 weeks and were diagnosed as GDM in the first pregnancy according to the OGTT value(when any one of the following values is met or exceeded to the 75-g OGTT:0 h[fasting],≥5.10 mmol/L;1 h,≥10.00 mmol/L;and 2 h,≥8.50 mmol/L).The prevalence of GDM recurrence and development of type 2 diabetes mellitus were calculated,and its related risk factors were analyzed.Results:In 6204 participants,there are 1002 women(1002/6204,16.15%)with a history of GDM and 5202 women(5202/6204,83.85%)without a history of GDM.There are significant differences in age(32.43±4.03 years vs.33.00±3.34 years vs.32.19±3.37 years,P<0.001),pregnancy interval(4.06±1.44 years vs.3.52±1.43 years vs.3.38±1.35 years,P=0.004),prepregnancy body mass index(BMI)(27.40±4.62 kg/m^(2)vs.23.50±3.52 kg/m^(2)vs.22.55±3.47 kg/m^(2),P<0.001),history of delivered macrosomia(22.7%vs.11.0%vs.6.2%,P<0.001)among the development of diabetes mellitus(DM),recurrence of GDM,and normal women.Moreover,it seems so important in the degree of abnormal glucose metabolism in the first pregnancy to the recurrence of GDM and the development of DM.There are significant differences in OGTT levels of the first pregnancy such as area under the curve of OGTT value(18.31±1.90 mmol/L vs.16.27±1.93 mmol/L vs.15.55±1.92 mmol/L,P<0.001),OGTT fasting value(5.43±0.48 mmol/L vs.5.16±0.49 mmol/L vs.5.02±0.47 mmol/L,P<0.001),OGTT 1-hour value(10.93±1.34 mmol/L vs.9.69±1.53 mmol/L vs.9.15±1.58 mmol/L,P<0.001),OGTT 2-hour value(9.30±1.66 mmol/L vs.8.01±1.32 mmol/L vs.7.79±1.38 mmol/L,P<0.001),incidence of impaired fasting glucose(IFG)(fasting plasma glucose≥5.6 mmol/L)(31.3%vs.14.6%vs.8.8%,P<0.001),and incidence of two or more abnormal OGTT values(68.8%vs.39.7%vs.23.9%,P<0.001)among the three groups.Using multivariate analysis,the factors,such as age(1.07[1.02-1.12],P=0.006),prepregnancy BMI(1.07[1.02,1.12],P=0.003),and area under the curve of OGTT in the first pregnancy(1.14[1.02,1.26],P=0.02),have an effect on maternal GDM recurrence;the factors,such as age(1.28[1.01-1.61],P=0.04),pre-pregnancy BMI(1.26[1.04,1.53],P=0.02),and area under the curve of OGTT in the first pregnancy(1.65[1.04,2.62],P=0.03),have an effect on maternal DM developed further.Conclusions:The history of GDM was significantly associated with a higher maternal risk for GDM recurrence during follow-up after the first pregnancy.The associated risk factors for GDM recurrence or development of DM include age,high pre-pregnancy BMI,history of delivered macrosomia,the OGTT level in the first pregnancy,such as the high area under the curve of OGTT,IFG,and two or more abnormal OGTT values.To prevent GDM recurrence,women with a history of GDM should do the preconception counseling before preparing next pregnancy. | Yumei Wei Juan Juan Rina Su Geng Song Xu Chen Ruiqin Shan Ying Li Shihong Cui Shangrong Fan Ling Feng Zishan You Haixia Meng Yan Cai Cuilin Zhang Huixia Yang | 2022 | Chinese Medical Journal2022，，6： | 7 |
| 2 | Incidence and Clinical Risk Factors for Preeclampsia and Its Subtypes:A Population-Based Study in Beijing,China显示文摘Objective:This study aimed to evaluate the incidence and associated clinical risk factors for preeclampsia(PE)and its subtypes in a large multicentre retrospective study of Beijing,China.Methods:This study was conducted as a secondary analysis from the Gestational diabetes mellitus Prevalence Survey(GPS),a multicentre retrospective cohort study,which included 15 hospitals in Beijing,China.This analysis included 15,003 pregnant women who delivered in Beijing from June 20th to November 30th,2013.The incidence of PE was calculated.Risk factors for PE,including maternal age,pre-gestational body mass index(BMI),parity,chronic hypertension,pre-existing diabetes,and gestational diabetes mellitus,were assessed.PE was defined as early-or late-onset PE based on clinical manifestations during the week of delivery,and mild or severe PE based on the severity of the disease.Logistic regression analysis was used to quantify the association with the risk factors,and data were displayed as odds risks(OR)and 95%confidence interval(CI).Results:The overall incidence of PE was 2.65%(397/15,003).The prevalence of early-onset and late-onset PE was 0.36%(54/15,003)and 2.29%(343/15,003),respectively.The prevalence of mild and severe PE was 0.91%(137/15,003)and 1.73%(260/15,003),respectively.Risk factors including high BMI considered overweight(adjusted odds risk(aOR):1.48;95%CI:1.06-2.05;P=0.02)and obesity(aOR:2.15;95%CI:1.50-3.08;P<0.001),nulliparity(aOR:1.73;95%CI:1.32-2.25;P<0.001),multiple gestation(aOR:4.58;95%CI:2.86-7.32;P<0.001),and chronic hypertension(aOR:34.95;95%CI:26.60-45.93;P<0.001),were associated with increased risk for PE.Only chronic hypertension(aOR:13.75;95%CI:4.78-39.58;P<0.001)was a significant risk factors for early-onset PE,whereas high BMI considered both overweight(aOR:1.54;95%CI:1.09-2.18;P=0.01)and obesity(aOR:2.23;95%CI:1.53-3.27;P<0.001),nulliparity(aOR:2.00;95%CI:1.49-2.68;P<0.001),multiple gestation(aOR:4.11;95%CI:2.40-7.05;P<0.001),and chronic hypertension(aOR:35.57;95%CI:26.66-47.47;P<0.001)were more relevant risk factors for late-onset PE.Risk factors including obesity(aOR:2.20;95%CI:1.28-3.76;P<0.01 and aOR:1.80;95%CI:1.16-2.80;P=0.01),nulliparity(aOR:2.28;95%CI:1.44-3.60;P<0.001 and aOR:1.48;95%CI:1.09-2.02;P=0.01),multiple gestation(aOR:5.50;95%CI:2.87-10.67;P<0.001 and aOR:3.51;95%CI:1.93-6.41;P<0.001),and chronic hypertension(aOR:33.98;95%CI:22.20-52.01;P<0.001 and aOR:35.03;95%CI:25.40-48.31;P<0.001)were associated with mild and severe PE.Moreover,we found that women with an increasing number of these risk factors had a higher risk of developing PE than pregnant women without any identified risk factors.Conclusion:The incidence of PE in this study is consistent with previous reported studies.Our findings indicate chronic hypertension and multiple gestation are the most important risk factors for PE in Chinese pregnant women.The risk for developing PE is associated with both the type and abundance of risk factors.These factors are valuable when monitoring patients at risk for PE,as this can help ensure an earlier diagnosis and prediction in women who are more likely to develop PE. | Li Lin Jing Huai Rina Su Chen Wang Boya Li Huixia Yang | 2021 | Maternal-Fetal Medicine2021，3，2： | 1 |
| 3 | Evaluation of the chemical profile from four germplasms sources of Pruni Semen using UHPLC-LTQ-Orbitrap-MS and multivariate analyses显示文摘Pruni Semen,the seed of several unique Prunus plants,is a traditional purgative herbal material.To determine the authentic sources of Pruni Semen,46 samples from four species were collected and analyzed.Ten compounds including multiflorin A(Mul A),a notable purative compound,were isolated and identified by chemical separation and nuclear magnetic resonance spectroscopy.Seventy-six communal components were identified by ultra-high performance liquid chromatography with linear ion trap-quadrupole Orbitrap mass spectrometry,and acetyl flavonoid glycosides were recognized as characteristic constituents.The flavonoids were distributed in the seed coat and cyanogenic glycosides in the kernel.Based on this,methods for identifying Pruni Semen from different sources were established using chemical fingerprinting,quantitative analysis of the eight principal compounds,hierarchical cluster analysis,principal component analysis,and orthogonal partial least squares discriminant analysis.The results showed that the samples were divided into two categories:one is the small seeds from Prunus humilis(Ph)and Prunus japonica(Pj),and the other is the big seeds from Prunus pedunculata(Pp)and Prunus triloba(Pt).The average content of Mul A was 3.02,6.93,0.40,and 0.29 mg/g,while the average content of amygdalin was 18.5,17.7,31.5,and 30.9 mg/g in Ph,Pj,Pp,and Pt,respectively.All the above information suggests that small seeds might be superior sources of Pruni Semen.This is the first comprehensive report on the identification of chemical components in Pruni Semen from different species. | Zihan Zhao Yue Liu Yushi Zhang Zeyu Geng Rina Su Lipeng Zhou Chao Han Zhanjun Wang Shuangcheng Ma Weidong Li | 2022 | Journal of Pharmaceutical Analysis2022，12，5： | 1 |
| 4 | The study of selective primary culture and determination of a breast cancer cell line in vitro显示文摘Objective The successful establishment of a tumor cell bank is based on the premise that the target cells can be cultured by a legitimate approach.In this experiment,we used primary culture to select and detect breast cancer cells in vitro,which can provide experimental ideas and methods for the establishment of a living tumor tissue cell bank.Methods Fifty-two specimens were collected over a two-year period from people with breast cancer who needed surgical treatment in our hospital.Cells were isolated and used to establish successful cell culture.Cell activity and cell purity were measured before liquid nitrogen cryopreservation.Results(1)At the initial culture stage,cells grew with adherence.Cell multiplication could be seen after the cell medium was exchanged three times.Cell viability was above 86%,while the viability of the target cells was above 75%,as detected by hematoxylin and eosin(HE)staining.(2)The number of breast cancer cells decreased,while the number of fibroblasts increased after five rounds of passage.(3)The success rate was 73.08%,which did not include polluted cells and those that were not successfully cryopreserved.Conclusion(1)breast cancer cells could be selected from primary culture in vitro through an appropriate method.(2)Exchange of the cell medium and further cell passage improved cell multiplication.(3)The experimental results could be monitored using trypan blue and HE staining.(4)The success of breast cancer cell culture in vitro could be used as a reference for other cell culture,so as to establish a tumor tissue cell bank. | Meng Ren Huixia Xu Xiangji Lu Bingping Wang Rina Su Hao Zhang Song Jiang Fengying Gao Yanwei Gao | 2020 | Oncology and Translational Medicine2020，6，2： | 1 |
| 5 | Risk Factors for Gestational Diabetes Mellitus(GDM)in Subsequent Pregnancy Among Women Without GDM History in China:A Multicenter Retrospective Study显示文摘Objective:This study aimed to determine the likelihood of gestational diabetes mellitus(GDM)in subsequent pregnancy among women without GDM history and to identify risk factors for GDM in subsequent pregnancy.Methods:This retrospective cohort study involved participants who delivered twice in same hospital of 18 research centers when delivered the second baby from January 2018 to December 2018.Finally 6204 women were enrolled and 5180 women without GDM history were analyzed further.Women were categorized as non-GDM or GDM based on the blood glucose values of the subsequent pregnancy,and the characteristics and GDM risk of these groups were compared.A univariate analysis of potential risk factors was performed using the Chi-squared test and/ort-test for qualitative or quantitative variables,respectively.Associations withP values<0.1 were chosen to be included in the multivariate binary logistic regression model.Results:In primary analysis of 6204 women,the incidence of GDM in subsequent pregnancy is 48.9%(490/1002)in women with GDM history and 16.1%(835/5202)in women without GDM history.In a further analysis for 5180 women without GDM at index pregnancy,compared with the non-GDM group,the GDM group had a significantly higher age,prepregnancy body mass index,and blood glucose value at each oral glucose tolerance test(OGTT)timepoint(fasting,1 h and 2 h)during the index and subsequent pregnancies,as well as higher weight retention during the interval between the two pregnancies(P<0.001).Age above 35 years in subsequent pregnancy(odds ratio(OR)=1.540,95%confidence interval(CI)=1.257-1.886,P<0.001),macrosomia in index pregnancy(OR=1.749,95%CI=1.277-2.395,P=0.001),OGTT blood glucose values in index pregnancy(fasting,OR=2.487,95%CI=1.883-3.285,P<0.001;1 h,OR=1.142,95%CI=1.051-1.241,P=0.002;2 h,OR=1.290,95%CI=1.162-1.432,P<0.001)and weight retention(OR=1.052,95%CI=1.035-1.068,P<0.001)were independent risk factors for GDM in subsequent pregnancy.Conclusion:For women without GDM history,GDM risk factors including age,macrosomia history,OGTT value,and weight retention,these can be evaluated before a subsequent pregnancy.Early warning and interventions are needed for women at high risk. | Geng Song Yumei Wei Juan Juan Rina Su Jianying Yan Mei Xiao Xianlan Zhao Meihua Zhang Yuyan Ma Haiwei Liu Jingxia Sun Kejia Hu Huixia Yang | 2023 | Maternal-Fetal Medicine2023，5，1： | 1 |

| 7 | Enhancing the treatment effects of tumor cell purified autogenous heat shock protein 70-peptide complexes on HER-3-overexpressing breast cancer显示文摘Objective The aim of this study was to enhance the treatment effect of tumor purified autogenous heat shock protein 70-peptide complexes(HSP70-PCs)on HER-3-overexpressing breast cancer.Methods In this study,we first studied the expression of HER-3 in breast cancer tissues and its relationship with patient characteristics.We then purified HSP70-PCs from primary breast cancer cells with different HER-2 and HER-3 expression profiles and determined the cytotoxicity of autogenous dendritic cells(DCs)and CD8+T cells induced by these complexes.Third,recombinant human HSP70-HER-3 protein complexes were used to inhibit the autogenous HSP70-PCs purified from HER-3-overexpressing breast cancer cells,and the resulting immunological response was examined.Results The results show that HSP70-PCs can be combined with recombinant HSP70-HER-3 protein complexes to induce stronger immunological responses than autogenous HSP70-PCs alone and that these treatments induce autogenous CD8+T cell killing of HER-3-positive breast cancer cells.Conclusion These findings provide a new direction for HSP70-DC-based immunotherapy for patients with HER-3-overexpressing breast cancer. | Xia Chen Xiaoming Zhang Xiangji Lu Meng Ren Rina Su Weishi Gao Yanwei Gao | 2021 | Oncology and Translational Medicine2021，7，4： | 0 |
| 8 | Inosine:A broad-spectrum anti-inflammatory against SARS-CoV-2 infection-induced acute lung injury via suppressing TBK1 phosphorylation显示文摘Severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)-induced cytokine storms constitute the primary cause of coronavirus disease 19(COVID-19)progression,severity,criticality,and death.Glucocorticoid and anti-cytokine therapies are frequently administered to treat COVID-19,but have limited clinical efficacy in severe and critical cases.Nevertheless,the weaknesses of these treatment modalities have prompted the development of anti-inflammatory therapy against this infection.We found that the broad-spectrum anti-inflammatory agent inosine downregulated proinflammatory interleukin(IL)-6,upregulated anti-inflammatory IL-10,and ameliorated acute inflammatory lung injury caused by multiple infectious agents.Inosine significantly improved survival in mice infected with SARS-CoV-2.It indirectly impeded TANK-binding kinase 1(TBK1)phosphorylation by binding stimulator of interferon genes(STING)and glycogen synthase kinase-3β(GSK3β),inhibited the activation and nuclear translocation of the downstream transcription factors interferon regulatory factor(IRF3)and nuclear factor kappa B(NF-κB),and downregulated IL-6 in the sera and lung tissues of mice infected with lipopolysaccharide(LPS),H1N1,or SARS-CoV-2.Thus,inosine administration is feasible for clinical anti-inflammatory therapy against severe and critical COVID-19.Moreover,targeting TBK1 is a promising strategy for inhibiting cytokine storms and mitigating acute inflammatory lung injury induced by SARS-CoV-2 and other infectious agents. | Ningning Wang Entao Li Huifang Deng Lanxin Yue Lei Zhou Rina Su Baokun He Chengcai Lai Gaofu Li Yuwei Gao Wei Zhou Yue Gao | 2023 | Journal of Pharmaceutical Analysis2023，13，1： | 0 |
