OBJECTIVE To explore the mechanism by which Qingre antai decoction improves pregnancy outcomes of threatened abortion rats with blood heat syndrome. METHODS The pregnant rats were randomly divided into normal group， model group， dydrogesterone group （0.002 g/kg）， and Qingre antai decoction group （44.1 g/kg）， with 13 rats in each group. Except for normal group， other groups were given warming-yang Chinese medicine and corresponding drugs intragastrically， once a day， for 12 consecutive days. On the 13th day of pregnancy， a single intragastric administration of mifepristone （5 mg/kg） was performed to establish a model of threatened abortion with blood heat syndrome. On the 14th day of pregnancy， the abortion rate and uterine coefficient were calculated； the pathological morphology of pregnant uterine was observed； the serum levels of 3，5，3′-triiodothyronine （T3）， thyroid hormone （T4）， thyroid stimulating hormone （TSH）， as well as the levels of vascular endothelial growth factor （VEGF） and nitric oxide （NO） in the pregnant uterus were all determined； the expressions of mRNA and protein related to Janus kinase 2 （JAK2）/signal transducer and activator of transcription 3 （STAT3） and phosphatidylinositol 3-kinase （PI3K）/protein kinase B （AKT） pathways were detected. RESULTS Compared with normal group， the model group exhibited endometrial tissue damage， a reduced number of decidual cells， and a significant presence of blood stasis within the uterus； abortion rate， the serum levels of T3， T4 and TSH， the mRNA expressions of JAK2， STAT3 and suppressor of cytokine signaling 3 （SOCS3） as well as protein expressions of p-JAK2， p-STAT3 and SOCS3 in the pregnant uterus were increased significantly （ P ＜0.05）； uterine coefficient， the levels of VEGF and NO in pregnant uterus， mRNA expressions of VEGFR2， PI3K， AKT and endothelial nitric oxide synthase（eNOS）， protein expressions of VEGFR2， PI3K and eNOS as well as phosphorylation level of AKT in the pregnant uterus were significantly reduced （ P ＜0.05）. Compared with model group， the endometrial tissue damage and congestion in the Qingre antai decoction group were significantly improved， and the levels of the aforementioned quantitative indicators were significantly reversed （ P ＜0.05）. CONCLUSIONS Qingre antai decoction can improve the pregnancy outcomes in rats with threatened abortion of blood heat syndrome， the mechanism of which may be associated with inhibiting JAK2/STAT3 pathway and activating PI3K/AKT pathway.

Objective:To analyze the effects of shift work on the renal function of oil workers and investigate whether there is a measured response relationship between shift work and renal dysfunction.Methods:In this study, oil workers who participated in physical examinations at the North China Oilfield Downhole Hospital were selected as the study subjects, and the physical examinations as well as questionnaires of the study subjects in 2017 and 2018 were collected as the baseline data, which included blood biochemical indexes, socio-demographic characteristics, history of life behaviors, occupational exposures, and occupational histories. Three follow-up surveys were subsequently conducted in April 2019, April 2020, and January 2021. The presence of renal dysfunction in the study population was determined based on the glomerular filtration rate tested at the medical examination hospital. The exposure of the study subjects to shift work was assessed using the weighted shift index (WSI), the relationship between different levels of shift work and renal dysfunction was analyzed using Cox regression, and the measure of WSI and renal dysfunction was explored by restricted cubic spline (RCS). response relationship.Results:A total of 2292 study participants were included in this study, and the prevalence density of renal dysfunction was 87.44 k/year, of which the prevalence of renal dysfunction in females (30.31%), those with per capita monthly income <2, 000 yuan (27.00%), those who consume alcohol (27.10%), those who are hypertensive (23.05%), those who are exposed to high temperatures (27.37%), those who are exposed to organic solvents (30.42%), and those who are engaged in shift work (25.87%) were to be found had a higher prevalence of renal dysfunction ( P<0.05). After correcting for age, sex, and other risk factors, there was a nonlinear association between intensity of shift work and renal dysfunction, with a hazard ratio ( HR) of 1.29 (95% CI: 0.98-1.59) for the development of renal dysfunction in petroleum workers for shift work performed at higher intensities, and moderate intensity of exposure to shift work reduced the risk of renal dysfunction in petroleum workers ( HR=0.54 with a 95% CI: 0.39-0.75, P<0.001) . Conclusion:Prolonged shift work increases the risk of renal dysfunction in oil workers, and the occurrence of renal dysfunction in oil workers is influenced by multiple factors.

Objective:To analyze the correlation and predictive value of obesity measurement indicators and cerebrovascular function scores in healthy physical examination population.Methods:It was a cross-sectional analysis that employed a simple random sampling method to select 3 496 individuals who underwent healthy physical examinations and cerebrovascular function tests at the Physical Examination Center of the Affiliated Hospital of Guizhou Medical University from January to December 2022. The general information, physical examination data, biochemical examination results, human component analyses, and cerebrovascular function integral data were collected. Based on cerebrovascular function scores, the participants were divided into high-risk group (0-24 points, 70 cases), medium-risk group (25-49 points, 317 cases), low-risk group (50-74 points, 787 cases), and normal group (≥75 points, 2 322 cases). Spearman correlation analysis and receiver operating characteristic (ROC) curve analyses were utilized to assess the correlation and predictive value of obesity measurement indicators and cerebrovascular function integrals.Results:Among the 3 496 subjects included in the analysis, 2 018 were male and 1 478 were female, with an average age of (46.4±7.9) years. The age, systolic blood pressure, diastolic blood pressure, body mass index, waist-to-hip ratio, body fat ratio, body fat content, visceral fat area, fasting blood glucose, total cholesterol, low-density lipoprotein, homocysteine all exhibited an increasing trend as the cerebrovascular function integral value decreased (all P<0.05). The skeletal muscle content in the low-risk group was significantly higher than those in the high-risk group, medium-risk group, and normal group [45.00 (36.80, 50.60) vs 44.10 (36.98, 50.45), 44.50 (37.80, 50.20), and 42.75 (36.30, 48.60) kg, respectively] ( P<0.05). The triglyceride level in the medium-risk group was higher when compared to those in the high-risk group, low-risk group, and normal group[1.87 (1.29, 2.70) vs 1.71 (1.24, 2.80), 1.75 (1.18, 2.70), and 1.43 (1.00, 2.14) mmol/L] ( P<0.05). The high-density lipoprotein level in the normal group was higher than the high-risk group, medium-risk group, and low-risk group[1.26 (1.05, 1.51) vs 1.16 (0.94, 1.36), 1.15 (0.99, 1.39), and 1.16 (0.97, 1.39) mmol/L, respectively] ( P<0.05). The increases in systolic blood pressure, diastolic blood pressure, body mass index, and body fat content were all moderately negatively correlated with the cerebrovascular function score ( rs=-0.347, -0.335, -0.370, and -0.340, respectively, all P<0.05). The increase in age ( OR=1.012, 95% CI: 1.002-1.022), systolic blood pressure ( OR=1.027, 95% CI: 1.017-1.036), diastolic blood pressure ( OR=1.028, 95% CI: 1.014-1.042), body mass index ( OR=1.157, 95% CI: 1.083-1.237), body fat rate ( OR=1.021, 95% CI: 1.007-1.035), and fasting blood glucose ( OR=1.072, 95% CI: 1.020-1.127) were all positively correlated with the decrease of the cerebrovascular function score; conversely, the increase in skeletal muscle content ( OR=0.967, 95% CI: 0.951-0.982) was negatively correlated with the decrease in cerebrovascular function score (all P<0.05). The area under the curve for the combined prediction of cerebrovascular function integral value by age, systolic blood pressure, diastolic blood pressure, body mass index, body fat rate, skeletal muscle content, and fasting blood glucose was 0.754. Conclusions:As the body mass index and body fat content increase and the skeletal muscle content decreases in the healthy physical examination population, the likelihood of abnormal cerebrovascular function integral values rises; the combination of age, systolic blood pressure, diastolic blood pressure, body mass index, body fat percentage, skeletal muscle content, and fasting blood glucose indicators can predict the increased risk of cerebrovascular function integral values.

Purpose To investigate the value of oxaliplatin-induced sinusoidal injury based on 3D CT image segmentation technology,and to analyze its variation.Materials and Methods A total of 24 patients with uneven hypoperfusion of liver parenchyma in the portal vein phase of enhanced CT after receiving oxaliplatin regimen chemotherapy from November 2019 to July 2021 in the Second Affiliated Hospital,Jiangxi Medical College,Nanchang University were analyzed,retrospectively.The imaging data of patients with epigastric CT enhancement before chemotherapy,early chemotherapy(1-3 cycles)and late chemotherapy(≥4 cycles)were collected.Two doctors used 3D Slicer software to segment and measure the liver volume and spleen volume at each stage on the CT image,as well as the hepatic hypoperfusion volume(HHV)of the liver in the portal vein phase after chemotherapy,and calculated the HHV ratio(HHVR),liver volume hepatomegaly rate and spleen volume splenomegaly rate,and performed statistical analysis.Results The ICC for HHV,liver volume and spleen volume measured by two doctors were 0.997(P=0.000),0.905(P=0.000)and 0.998(P=0.000),respectively.Reddish-brown could be used to represent normal liver parenchyma,and blue could be used to render the HHV area to achieve HHV visualization.There was a statistically significant increase in HHVR in the late stage of chemotherapy compared with the early stage of chemotherapy[(74.35±30.56)%vs.(57.15±30.53)%;t=3.226,P=0.004].In the early and late stages of chemotherapy,the liver volume and spleen volume increased statistically significantly compared with those before chemotherapy(all P<0.05),and the spleen volume splenomegaly rate value in the late stage of chemotherapy increased statistically compared with the early stage of chemotherapy[25.75(7.40,70.66)%vs.17.86(4.44,63.59)%;Z=2.229,P=0.026].The Pearson correlation coefficient between liver volume hepatomegaly rate and HHVR was 0.377(P=0.008),and the Spearman correlation coefficient between spleen volume splenomegaly rate and HHVR was 0.296(P=0.041).Conclusion The application of 3D CT image segmentation technology to measure the HHV caused by oxaliplatin has good consistency,and can realize the visual display of HHV.With the increase of chemotherapy cycle,the extent of oxaliplatin-induced sinusoidal injury shows an increasing trend,and is positively correlated with hepatomegaly and splenomegaly.

BACKGROUND:In recent years,the development of liver organoids has made it a hot spot in the field of international liver disease research,but there is still no article on the bibliometric analysis of liver organoids. OBJECTIVE:To explore the hot trends in liver organoids in the last 20 years based on bibliometrics and visualization analysis. METHODS:We searched the articles about liver organoids in the Web of Science Core Collection from January 1,2002 to November 12,2022.Origin,Office,and CiteSpace software were used for bibliometrics and visualization analysis.We statistically analyzed the number of annually published articles,countries,institutions,authors,journals,and keywords of the articles by generating charts. RESULTS AND CONCLUSION:The number of articles,citation frequency,institutions and personnel involved in the research about liver organoids showed an overall upward trend in the last 20 years,indicating that the field was growing rapidly and attention was increasing.The USA had published the most papers and had the strongest influence in this field.Although it had invested a lot of time and energy,the number of papers published by a single research institution in the USA was not the highest among many research institutions.China was second only to the USA in the number of publications,with the Chinese Academy of Sciences and Fudan University leading the list.Utrecht University in the Netherlands was the institution with the most publications.Clevers H was the author with the highest number of articles.The article with the highest co-citation frequency was"Long-term culture of genome-stable bipotent stem cells from adult human liver".The main fields of study for liver organoids were Molecular Science,Biology,and Immunology.The most frequently occurring keywords were stem cell,in vitro,and culture.The research hotspots in the liver organoids field were mainly focused on in vitro stem cell three-dimensional culture,differentiation and gene expression.

Objective:To verify the reliability and validity of the Chinese Version of Biological Rhythms Interview of Assessment in Neuropsychiatry (BRIAN-C) in patients with major depressive disorder(MDD).Methods:A total of 122 patients with MDD and 122 controls were recruited and measured with the BRIAN-C, 16-Item Quick Inventory of Depressive Symptomatology Self-Report (QIDS-SR16), 7-Item Generalized Anxiety Disorder Scale(GAD-7) and 6-Item Short Form Health Survey(SF-6). The index D and correlation analysis were conducted to evaluate the discrimination and homogeneity of the items, respectively. The Cronbach′s α coefficient, Spearman-Brown coefficient, intraclass correlation coefficient ( ICC) and retest correlation coefficient were conducted to evaluate the reliability.Confirmatory factor analysis, correlation analysis and the receiver operating characteristic (ROC) curve were conducted to evaluate the construct validity, criterion validity and prediction validity, respectively. Results:The item distinction and homogeneity analysis showed significant differences ( P<0.05). The Cronbach′s α coefficient and the Spearman-Brown coefficient were 0.911 and 0.807, while the ICC and the correlation coefficient r of test-retest reliability were 0.639 (95% confidence interval( CI):0.375-0.729) and 0.43 ( P=0.001), respectively. Confirmatory factor analysis showed that the fit indexes χ 2/dF=1.937, goodness-of-fit index(GFI)=0.822, comparative fit index (CFI)=0.877, Tucker-lewis index (TLI)=0.855, and root mean square error of approximation (RMSEA)=0.088. The score of BRIAN-C was significantly correlated with that of QIDS-SR16, GAD-7 or SF-6 ( r=0.74, 0.46, -0.69, all P<0.05).The ROC curve suggested that the area under curve (AUC) was 0.939 (95% CI: 0.909-0.970, P<0.05) for distinguishing MDD patients from controls. The optimal cut-off was 29, with 0.861 sensitivity and 0.926 specificity. Conclusions:The BRIAN-C scale has good reliability and validity, which is supposed to be used in Chinese cultural background to evaluate the biorhythms in patients with MDD.
