ABSTRACT

BACKGROUND@#Fetal weight is an important parameter to ensure maternal and child safety. The purpose of this study was to use three-dimensional (3D) limb volume ultrasound combined with fetal abdominal circumference (AC) measurement to establish a model to predict fetal weight and evaluate its efficiency.@*METHODS@#A total of 211 participants with single pregnancy (28-42 weeks) were selected between September 2017 and December 2018 in the Beijing Obstetrics and Gynecology Hospital of Capital Medical University. The upper arm (AVol)/thigh volume (TVol) of fetuses was measured by the 3D limb volume technique. Fetal AC was measured by two-dimensional ultrasound. Nine cases were excluded due to incomplete information or the interval between examination and delivery >7 days. The enrolled 202 participants were divided into a model group (134 cases, 70%) and a verification group (68 cases, 30%) by mechanical sampling method. The linear relationship between limb volume and fetal weight was evaluated using Pearson Chi-squared test. The prediction model formula was established by multivariate regression with data from the model group. Accuracy of the model formula was evaluated with verification group data and compared with traditional formulas (Hadlock, Lee2009, and INTERGROWTH-21st) by paired t-test and residual analysis. Receiver operating characteristic curves were generated to predict macrosomia.@*RESULTS@#AC, AVol, and TVol were linearly related to fetal weight. Pearson correlation coefficient was 0.866, 0.862, and 0.910, respectively. The prediction model based on AVol/TVol and AC was established as follows: Y = -481.965 + 12.194TVol + 15.358AVol + 67.998AC, R2adj = 0.868. The scatter plot showed that when birth weight fluctuated by 5% (i.e., 95% to 105%), the difference between the predicted fetal weight by the model and the actual weight was small. A paired t-test showed that there was no significant difference between the predicted fetal weight and the actual birth weight (t = -1.015, P = 0.314). Moreover, the residual analysis showed that the model formula's prediction efficiency was better than the traditional formulas with a mean residual of 35,360.170. The combined model of AVol/TVol and AC was superior to the Lee2009 and INTERGROWTH-21st formulas in the diagnosis of macrosomia. Its predictive sensitivity and specificity were 87.5% and 91.7%, respectively.@*CONCLUSION@#Fetal weight prediction model established by semi-automatic 3D limb volume combined with AC is of high accuracy, sensitivity, and specificity. The prediction model formula shows higher predictive efficiency, especially for the diagnosis of macrosomia.@*TRIAL REGISTRATION@#ClinicalTrials.gov, NCT03002246; https://clinicaltrials.gov/ct2/show/NCT03002246?recrs=e&cond=fetal&draw=8&rank=67.

ABSTRACT

BACKGROUND@#Prenatal evaluation of fetal lung maturity (FLM) is a challenge, and an effective non-invasive method for prenatal assessment of FLM is needed. The study aimed to establish a normal fetal lung gestational age (GA) grading model based on deep learning (DL) algorithms, validate the effectiveness of the model, and explore the potential value of DL algorithms in assessing FLM.@*METHODS@#A total of 7013 ultrasound images obtained from 1023 normal pregnancies between 20 and 41 + 6 weeks were analyzed in this study. There were no pregnancy-related complications that affected fetal lung development, and all infants were born without neonatal respiratory diseases. The images were divided into three classes based on the gestational week: class I: 20 to 29 + 6 weeks, class II: 30 to 36 + 6 weeks, and class III: 37 to 41 + 6 weeks. There were 3323, 2142, and 1548 images in each class, respectively. First, we performed a pre-processing algorithm to remove irrelevant information from each image. Then, a convolutional neural network was designed to identify different categories of fetal lung ultrasound images. Finally, we used ten-fold cross-validation to validate the performance of our model. This new machine learning algorithm automatically extracted and classified lung ultrasound image information related to GA. This was used to establish a grading model. The performance of the grading model was assessed using accuracy, sensitivity, specificity, and receiver operating characteristic curves.@*RESULTS@#A normal fetal lung GA grading model was established and validated. The sensitivity of each class in the independent test set was 91.7%, 69.8%, and 86.4%, respectively. The specificity of each class in the independent test set was 76.8%, 90.0%, and 83.1%, respectively. The total accuracy was 83.8%. The area under the curve (AUC) of each class was 0.982, 0.907, and 0.960, respectively. The micro-average AUC was 0.957, and the macro-average AUC was 0.949.@*CONCLUSIONS@#The normal fetal lung GA grading model could accurately identify ultrasound images of the fetal lung at different GAs, which can be used to identify cases of abnormal lung development due to gestational diseases and evaluate lung maturity after antenatal corticosteroid therapy. The results indicate that DL algorithms can be used as a non-invasive method to predict FLM.

ABSTRACT

OBJECTIVE@#To investigate the effect of etoposide (ETO) on elimination of chronic myeloid leukemia (CML) stem cells by imatinib mesylate(IM) in vivo.@*METHODS@#SCL-tTA/BCR-ABL mice were used as CML animal model. Flow cytometry was used to assess the effect of ETO alone or in combination with IM on the number of leukemia stem cell (LSC) in bone marrow and spleen, and peripheral blood neutrophils in CML mice and normal control FVB mice.@*RESULTS@#The results showed that in CML mice, the number and proportion of LSC in bone marrow and the proportion of neutrophils in peripheral blood decreased significantly after ETO and IM combined treatment, and the degree of decrease was more significant than that of both alone. While in wild type FVB mice, the combination of ETO and IM showed no significant effect on the number and proportion of LSK cells in bone marrow and the proportion of neutrophils in spleen.@*CONCLUSION@#ETO can selectively enhance elimination of CML LSC by IM in vivo.

ABSTRACT

Objective:To investigate the effect of different dose of Realgar compatible with Indigo Naturalis on the transitional constituents of Indigo Naturalis in rat serum based on the compatibility of Qinghuangsan.Method:Indigo Naturalis test solution, the drug-containing serum of three different proportions of Qinghuangsan (10 g of Indigo Naturalis compatible with 52.5, 105, 210 mg of Realgar for group A, B and C, respectively) and blank serum were detected by UPLC-Q-TOF-MS/MS, in combination with the chemical components identified in Indigo Naturalis test solution, the differences of transitional constituents of Indigo Naturalis in rat serum from the group A, B and C were analyzed. HL-60 cells (human leukemia cells) were treated with the three groups of Qinghuangsan drug-containing serum and the effect of drug-containing serum on the activity of HL-60 cells was detected by cell counting kit-8 (CCK-8) assay.Result:A total of 19, 22, 25 of transitional constituents were detected in Qinghuangsan drug-containing serum from group A, B and C, respectively. The three groups of drug-containing serum all contained 5 prototype components from Indigo Naturalis test solution, including tryptanthrin, indigo, indirubin, 2-aminobenzoic acid and N-phenyl-2-naphthylamine, respectively. The results of CCK-8 assay showed that Qinghuangsan drug-containing serum of group C had the strongest inhibitory effect on HL-60 cells.Conclusion:After fixed Indigo Naturalis dose, with the increase of Realgar dose, the transitional constituents in rat serum increase and the inhibitory effect on HL-60 cells also gradually enhances, which indicates that Realgar may promote the absorption of active components in Indigo Naturali in vivo, thus enhance the efficacy, further explains the compatibility law and pharmacodynamic material basis of different proportions of Realgar and Indigo Naturalis.

ABSTRACT

BACKGROUND@#The predictive value of hemoglobin A1c (HbA1c) levels in non-diabetic patients with myocardial infarction undergoing percutaneous coronary intervention (PCI) is still controversial. This study aimed to evaluate whether HbA1c levels were independently associated with adverse clinical outcomes in non-diabetic patients with coronary artery disease (CAD) who had undergone PCI by performing a meta-analysis of cohort studies.@*METHODS@#This meta-analysis included non-diabetic patients with CAD who had undergone PCI. A systematic search for publications listed in the PubMed, Embase, and Cochrane Library databases from commencement to December 2018 was conducted. Studies evaluating the adverse clinical outcomes according to abnormal HbA1c levels in non-diabetic patients diagnosed with CAD who had undergone PCI were eligible. The primary outcomes were long-term all-cause deaths and long-term major adverse cardiac events, and the secondary outcome was short-term all-cause deaths. The meta-analysis was conducted with RevMan 5.3 and Stata software 14.0. Odds ratios (ORs) were pooled using a random or fixed-effects model, depending on the heterogeneity of the included studies. Sub-group analysis or sensitivity analysis was conducted to explore potential sources of heterogeneity, when necessary.@*RESULTS@#Six prospective cohort studies involving 10,721 patients met the inclusion criteria. From the pooled analysis, abnormal HbA1c levels were associated with increased risk for long-term all-cause death (OR 1.39, 95% confidence interval [CI] 1.16-1.68, P = 0.001, I = 45%). Sub-group analysis suggested that abnormal HbA1c levels between 6.0% and 6.5% predicted higher long-term major adverse cardiac event (including all-cause deaths, non-fatal myocardial infarction, target lesion revascularization, target vessel revascularization, recurrent acute myocardial infarction, heart failure requiring hospitalization, and stent thrombosis) risk (OR 2.05, 95% CI 1.46-2.87, P < 0.001, I = 0). Contrarily, elevated HbA1c levels were not associated with increased risk of short-term all-cause death (OR 1.16, 95% CI 0.88-1.54, P = 0.300, I = 0).@*CONCLUSIONS@#An abnormal HbA1c level is an independent risk factor for long-term adverse clinical events in non-diabetic patients with CAD after PCI. Strict control of HbA1c levels may improve patient survival. Further studies in different countries and prospective cohort studies with a large sample size are required to verify the association.

ABSTRACT

OBJECTIVE@#To compare the clinical effects of a modified socket shield technique (SST) and the conventional immediate implant placement in the esthetic zone.@*METHODS@#Twenty-four patients with one hopeless upper incisor were consecutively enrolled in this study. All patients were scheduled for immediate implant placement. Twelve patients underwent a modified SST (experimental group) whereas the others underwent conventional procedures (control group). Radiographic and clinical data were obtained preoperatively, immediately after surgery, and 12 months after surgery. The success rate of the implants, the pink esthetic score (PES) and patient satisfaction were analyzed. Statistical analysis was conducted using SPSS 21.0 software.@*RESULTS@#One year after operation, the success rate of the implants was 100% in both groups. The PES and patient satisfaction of the experimental group were significantly higher than those of the control group (P<0.05). The buccal bone plate resorbed less in the experimental group than in the control group (P<0.05).@*CONCLUSIONS@#The modified SST is advantageous over the conventional immediate implant placement in terms of buccal bone and soft tissue maintenance.

ABSTRACT

BACKGROUND@#The mortality of cardiovascular disease is constantly rising, and novel biomarkers help us predict residual risk. This study aimed to evaluate the predictive value of serum homocysteine (HCY) levels on prognosis in patients with ST-segment elevation myocardial infarction (STEMI).@*METHODS@#The 419 consecutive patients with STEMI, treated at one medical center, from March 2010 to December 2015 were retrospectively investigated. Peripheral blood samples were obtained within 24 h of admission and HCY concentrations were measured using an enzymatic cycling assay. The patients were divided into high HCY level (H-HCY) and low HCY level (L-HCY) groups. Short- and long-term outcomes were compared, as were age-based subgroups (patients aged 60 years and younger vs. those older than 60 years). Statistical analyses were mainly conducted by Student t-test, Chi-squared test, logistic regression, and Cox proportional-hazards regression.@*RESULTS@#The H-HCY group had more males (84.6% vs. 75.4%, P = 0.018), and a lower prevalence of diabetes (20.2% vs. 35.5%, P < 0.001), compared with the L-HCY group. During hospitalization, there were seven mortalities in the L-HCY group and 10 in the H-HCY group (3.3% vs. 4.8%, P = 0.440). During the median follow-up period of 35.8 (26.9-46.1) months, 33 (16.2%) patients in the L-HCY group and 48 (24.2%) in the H-HCY group experienced major adverse cardiovascular and cerebrovascular events (MACCE) (P = 0.120). History of hypertension (hazard ratio [HR]: 1.881, 95% confidence interval [CI]: 1.178-3.005, P = 0.008) and higher Killip class (HR: 1.923, 95% CI: 1.419-2.607, P < 0.001), but not HCY levels (HR: 1.007, 95% CI: 0.987-1.027, P = 0.507), were significantly associated with long-term outcomes. However, the subgroup analysis indicated that in older patients, HCY levels were significantly associated with long-term outcomes (HR: 1.036, 95% CI: 1.011-1.062, P = 0.005).@*CONCLUSION@#Serum HCY levels did not independently predict in-hospital or long-term outcomes in patients with STEMI; however, among elderly patients with STEMI, this study revealed a risk profile for late outcomes that incorporated HCY level.

ABSTRACT

The inflammatory response is involved in the pathogenesis of the most common types of heart disease.Sanguinarine (SAN) has various pharmacological properties such as anti-inflammatory,antioxidant,antibacterial,antitumor,and immune-enhancing properties.However,few studies have investigated the effects of SAN on lipopolysaccharide (LPS)-induced inflammatory and apoptotic responses in H9c2 cardiomyocytes.Therefore,in this study,H9c2 cells were co-treated with SAN and LPS,and the mRNA levels of pro-inflammation markers and the apoptosis rate were measured to clarify the effect of SAN on cardiac inflammation.The underlying mechanism was further investigated by detecting the activation of Toll-like receptor (TLR)4/nuclear factor-κB (NF-κB) signaling pathways.As a result,increased mRNA expression of interleukin (IL)-1 β,IL-6,and TNFα induced by LPS was attenuated after SAN treatment;LPS-induced apoptosis of H9c2 cardiomyocytes and cleaved-caspase 8,9,3 were all significantly reduced by SAN.Further experiments showed that the beneficial effect of SAN on blocking the inflammation and apoptosis of H9c2 cardiomyocytes induced by LPS was associated with suppression of the TLR4/NF-κB signaling pathway.It was suggested that SAN suppressed the LPS-induced inflammation and apoptosis of H9c2 cardiomyocytes,which may be mediated by inhibition of the TLR4/NF-κB signaling pathway.Thus,SAN may be a feasible therapy to treat sepsis patients with cardiac dysfunction.

ABSTRACT

Objective To investigate the level and influencing factors for self-efficacy among elders with hypertension in Zhoushan and to provide the reference for improving the self-efficacy of elders with hypertension. Methods The stratified sampling method was used to select elders with hypertension from 4 streets (townships) in urban and rural of Zhoushan in 2016. Four communities were selected from each street (townships) as sample units and using the random sampling to select 50 patients from every community. The investigation was performed with unified questionnaire. The influencing factors for self-efficacy were analyzed with logistic regression. Results The average score of the self-efficacy was 34.13±5.17. Among the investigated 738 elders with hypertension, more than half of them were scored 1ess than 2 in two items, which were blood pressure monitoring (86.99%) and persistent physical exercise (50.95%) . Scoring index of compliance behavior of hypertension was the lowest, only 63.93% . By multivariate logistic regression analysis, those patients who were female (OR=2.34, 95% CI: 1.55-3.53) , educated (ORprimary=1.72, 95% CI: 1.09-2.69; ORjunior =2.25, 95% CI: 1.13-4.46;ORsenior and above=2.46, 95% CI: 1.06-5.71), with high level of drug compliance (ORmedium=1.72, 95%CI: 1.09-2.69; ORhigh=2.12, 95% CI: 1.38-3.26) were more likely to get high level of self-efficacy. Patients who monitored blood pressure only uncomfortable were more likely to get low level of self-efficacy (OR=0.22, 95% CI: 0.08-0.68) . Conclusion More than half of community-dwelling elders with hypertension had a middle level self-efficacy in Zhoushan, who need further improvement. Corresponding interventions should be developed to strengthen the self-efficacy, which can help patients improve self-management of hypertension and establish a healthy life style.

ABSTRACT

Aim To establish a UPLC method for the determination of the concentration of hainanolidol in plasma of rats, and study the pharmacokinetics of hain-anolidol in rat plasma after single dose i. v. administra-tion of hainanolidol (1, 2, 4 mg·kg-1). Methods The UPLC method for the determination of hainanolidol in rat plasma was established using hainanolide as in-ternal standard. The mobile phase was methanol-water (47 ∶ 53), the flow rate was 0.17 mL·min-1, and the detection wavelength was UV 326 nm. The plasma concentration of hainanolidol in rats was determined by UPLC after single-dose intravenous injection in rats with 1, 2 and 4 mg·kg-1of hainanolidol, and the pharmacokinetic parameters were calculated by DAS2.1. Results The result of calibration curve was linear over the range of 0.05 ~10.00 mg·L-1( r = 0.999 6) . The lower limit of quantification was 0.05 mg·L-1. The intra-day and inter-day precision were both lower than 5% , and the extraction recoveries were higher than 85% , respectively. The validated method was successfully applied to the pharmacokinetic study after i. v administration of hainanolidol in rats with do-ses of 1, 2 and 4 mg·kg-1. The T1/2was (39.82 ± 0.92), (40.11 ± 0.79) and (41.61 ± 2.07) min, respectively. The AUC0-twas ( 65.77 ± 1.08 ) , (130.48 ± 1.26) and (268.75 ± 1.24) min·mg· L-1, respectively. Conclusion A simple and specific UPLC method for the analysis of hainanolidol is suc-cessfully developed, which could be applied to phar-macokinetic study in rat plasma.

ABSTRACT

<p><b>OBJECTIVE</b>To explore the risk factors of velamentous umbilical cord insertion(VCI)and the impact of VCI on perinatal outcomes.</p><p><b>METHODS</b>The clinical data of 588 VCI patients who were treated in Beijing Gynecology and Obstetrics Hospital from January 2006 to January 2011 were retrospectively analyzed. In addition,61,143 non-VCI subjects were enrolled as the control group. The possible risk factors of VCI and the impact of VCI on perinatal outcomes were analyzed. In addition,the causes of perinatal deaths were analyzed.</p><p><b>RESULTS</b>The gemellary pregnancy,multiple pregnancy,in vitro fitilization(IVF),placenta praevia,and placenta succenturiata/placenta bipartite were found to be the risk factors of VCI. The incidences of low birth weight,intrauterine growth restriction,asphyxia of newborns,deaths of fetuses or neonates,and single umbilical artery in the VCI group were significantly higher than those in the control group(all P<0.05). In 678 perineonates with VCI,the total death toll of perineonates was 7(1.0%),among whom the death causes included angiorrhexis of placenta praevia(n=1),preterm birth and low birth weight(n=3),torsion of cord(n=1),prolapse of cord(n=1),and placental abruption(n=1).</p><p><b>CONCLUSIONS</b>The risk factors of VCI should be carefully monitored. A diagnosis of VCI,if any,should be correctly made by using modern ultrasound techniques before delivery,so as to lower the mortality of perineonates.</p>

ABSTRACT

The present study is to elucidate the mechanisms underlying Gleevec-induced apoptosis of chronic myeloid leukemia (CML) K562 cells in vitro. The apoptotic cell death and cell cycle distribution after Gleevec treatment and the effect of PDCD4 siRNA on Gleevec-induced apoptosis of K562 cells were analyzed by flow cytometry. The effect of Gleevec on p-Crkl, caspase-3, PARP and PDCD4 protein levels, and the knockdown efficacy of PDCD4 siRNA were detected by Western blotting. The results showed that Gleevec dramatically suppressed the phosphorylation level of Crkl in a dose-dependent manner and induced significant apoptosis and G0/G1 cell cycle arrest of K562 cells in time- and dose-dependent manners. In addition, Gleevec activated caspase-3 and its downstream substrates PARP, and the caspase pan inhibitor Z-VAD-FMK (50 micromol x L(-1)) markedly reduced Gleevec-induced apoptosis from 47.97% +/- 10.56% to 31.05% +/- 9.206% (P < 0.05). Moreover, Gleevec significantly increased the protein expression of programmed cell death 4 (PDCD4). PDCD4 knockdown by siRNA reduced Gleevec-induced apoptosis from 46.97% +/- 14.32% to 42.8% +/- 11.43%. In summary, Gleevec induced apoptosis in K562 cells via caspase-3 activation.

ABSTRACT

<p><b>OBJECTIVE</b>To observe the effect of hesperidin on behavior and hypothalamic-pituitary-adrenal (HPA) axis of ratmodel of chronic stress-induced depression.</p><p><b>METHOD</b>Chronic unpredictable mild stress (CUMS) was used to establish the rat depression model. Sixty male SD rats were divided randomly into six groups: the normal group, the model group, the hesperidin (40, 80, 160 mg x kg(-1)) group and the positive fluoxetine (10 mg x kg(-1)) group. They were orally administered with drugs for three weeks. The sucrose preference test and the forced swimming test (FST) were assayed to detect animal behavior. The levels of corticosterone (CORT) in serum, mRNA of corticotropin release factor (CRF) in hypothalamus as well as protein expression of glucocorticoid receptor (GR) in paraventricular nucleus (PVN) were determined to clarify the anti-depression effect and mechanism of hesperidin.</p><p><b>RESULT</b>Compared with the model group, rats in the hesperidin (40, 80, 160 mg x kg(-1)) treatment group showed significant increase in the sucrose consumption and decrease in the immobility time in FST to varying degrees. Meanwhile, the excessively high serum CORT and adrenal index of CUMS rats were reversed by treatment with hesperidin. In addition, hesperidin inhibited CRF mRNA expression in hypothalamus and up-regulated GR protein expression in PVN among CUMS rats.</p><p><b>CONCLUSION</b>Hesperidin could effectively improve the behavior of CUMS rats and show the anti-depression effect. Its mechanisms may be related to the function of regulating HPA axis.</p>

ABSTRACT

Objective To evaluate the significance of standardized ultrasound examination of fetal structures in the ifrst trimester (11-13+6 weeks). Methods The ultrasound data of 29 858 fetuses who underwent the ifrst trimester screening were analyzed retrospectively in Beijing Obstetrics and Gynecology Hospital of Capital Medical University from January 2010 to December 2012 and followed up the cases with structural abnormalities and increased nuchal translucency (NT). Results Among 29 858 fetuses, 328 structural defects were detected in 284 fetuses (0.95%) by ultrasound in the first trimester, including fetal hydrops (124 cases), choroid plexus cysts (36 cases), exencephaly (32 cases), gastroschisis (24 cases), exomphalos (22 cases), cardiac defects (19 cases), megacystis (14 cases), spine abnormalities (10 cases), meningoceles/encephaloceles (9 cases), alobar holoprosencephaly (8 cases), hydrocephaly (7 cases), abnormalities of extremities (7 cases), acrania (6 cases), amniotic band syndrome (4 cases), abdominal cyst (3 cases) and conjoined twins (3 cases). Pregnancy was terminated in all cases (115) with exencephaly, gastroschisis, exomphalos, meningoceles/encephaloceles, alobar holoprosencephaly, hydrocephaly,abnormalities of extremities, acrania, amniotic band syndrome and conjoined twins, and the defects were verified by the gross appearance of fetuses. Two cases of megacystis were turned out to be normal during follow-up while 1 case was proved to be aneuploid and 1 other case progressed to multiple abnormalities during the second trimester. Most choroid plexus cysts, except 1 case of aneuploid, were normal during the second and the third trimester follow-ups by ultrasound. Thirteen cases of fetal hydrops were found to be aneuploids and 4 hydrops cases were proved to be complicated with other structural defects during the second and the third trimester. NT was increased in 422 cases (1.41%), among which 122 cases (28.91%) were complicated with structural defects and/or fetal hydrops. Ninty-nine cases with increased NT underwent chromosomal examination and 38 cases were found to be aneuploides. During the follow-up of 298 cases with increased NT who continued pregnancy, 21 structural abnormalities were found, including cardiac defects (14 cases), neural abnormalities (4 cases) and diaphragmatic hernia (3 cases). Conclusion The standardized fetal ultrasound in the first trimester is a effective tool for the screening of aneupolides and major structural abnormalities.
