RESUMO
BACKGROUND:Currently,the verification of the precision of personalized bone models is usually performed by methods such as paired t-tests or intraclass correlation coefficient,but such methods often require the production of large batches of models,which do not satisfy the need for immediate use of personalized models. OBJECTIVE:To study the feasibility of establishing the equivalent model to verify the precision of the personalized bone model rapidly. METHODS:Bone CT images of three adults were randomly obtained for reconstruction.3D printing was used to create personalized bone models,and then the personalized bone models were scanned using CT and reconstructed.Mimics was used to compare the reconstructed models of bone CT images with the bone CT images.Geomagic Studio was used to analyze the fitting deviation between the reconstruction model of personalized bone model CT image and the reconstruction model of skeletal CT image.The 3D-printed personalized bone model was measured against the measurement positions and dimensions marked on the reconstruction model of skeletal CT image,and the error was calculated. RESULTS AND CONCLUSION:(1)By comparing the reconstructed bone CT image model with the bone CT scan image,the two were compatible in terms of anatomical structure and morphology,and the contours almost overlapped.(2)By fitting bias analysis,the standard bias was 0.176,0.226,and 0.143 mm in order,and all the results were<0.25 mm.(3)By measuring and calculating the model,the mean relative errors were 0.44%,0.21%,and 0.13%,and all the results were within 5%error.(4)The constructed equivalent model was in line with the basic conditions for making personalized bone models.The established equivalent model met the clinical needs and design requirements,and it was feasible to use the method of the equivalent model to verify the precision of the personalized bone model quickly.(5)This method could provide a targeted and rapid way to verify the precision of personalized bone models.It could achieve the goal of providing immediate clinical use without the need to produce large batches of models compared to conventional methods such as paired t-tests or intraclass correlation coefficient.

RESUMO
The development of animal early embryos commences with the reprogramming of terminally differentiated gametes into totipotent zygotes following fertilization. During the initial stages of embryonic development, the transcriptional levels of zygotic genome remain silent and maternal gene products dominate the regulation of development. As embryonic development progresses, the maternal gene products undergo phased degradation while the zygotic genome gradually activates transcription, marking the transition from the maternal regulation to the zygotic genome regulation in early embryonic development, which is also referred to as the maternal-zygotic transition (MZT). Zygotic genome activation (ZGA) is a critical turning process in this transition, and its accurate occurrence is crucial for early embryonic development and cell fate decisions. However, the regulatory factors and molecular mechanisms of ZGA remain poorly understood. Studies have shown that ZGA varies greatly among different species and may be affected by a variety of regulatory factors such as DNA methylation, histone modification, non-coding RNA, chromatin remodeling and ZGA related factors. Here, we review the research progress of the above regulatory factors affecting ZGA, which can provide valuable insights for further investigations into the ZGA related mechanisms of early embryos.

RESUMO
Background/Aims@#Roxadustat, an oral medication for treating renal anemia, is a hypoxia-inducible factor prolyl hydroxylase inhibitor used for regulating iron metabolism and promoting erythropoiesis. To investigate the efficacy and safety of roxadustat in patients undergoing peritoneal dialysis (PD) with erythropoietin hyporesponsiveness. @*Methods@#Single-center, retrospective study, 81 PD patients (with erythropoietin hyporesponsiveness) were divided into the roxadustat group (n = 61) and erythropoiesis-stimulating agents (ESAs) group (n = 20). Hemoglobin (Hb), total cholesterol, intact parathyroid hormone (iPTH), brain natriuretic peptide (BNP), related indicators of cardiac function and high-sensitivity C-reactive protein (hs-CRP) were collected. Additionally, adverse events were also recorded. The follow-up period was 16 weeks. @*Results@#The two groups exhibited similar baseline demographic and clinical characteristics. At baseline, the roxadustat group had a mean Hb level of 89.8 ± 18.9 g/L, while the ESAs group had a mean Hb level of 95.2 ± 16.0 g/L. By week 16, the Hb levels had increased to 118 ± 19.8 g/L (p 0.05) in the ESAs group. The efficacy of roxadustat in improving anemia was not influenced by baseline levels of hs-CRP and iPTH. Cholesterol was decreased in the roxadustat group without statin use. An increase in left ventricular ejection fraction and stabilization of BNP were observed in the roxadustat group. @*Conclusions@#For PD patients with erythropoietin hyporesponsiveness, roxadustat can significantly improve renal anemia. The efficacy of roxadustat in improving renal anemia was not affected by baseline levels of hs-CRP0 and iPTH.

ObjectiveTo study the genetic diversity and genetic relationship of Pinellia ternata germplasm resources and provide the basis for germplasm identification, variety breeding, and resource conservation. MethodIn this study, 27 P. ternata were used as experimental materials to determine seven phenotypic characters, such as plant height, leaf length, and leaf width. Simple sequence repeats (SSR) primers were designed based on P. ternata transcriptome data, and polymerase chain reaction (PCR) amplification was performed on 27 P. ternata samples. The genetic diversity of P. ternata germplasm was analyzed by POPGENE32, PowerMarker V3.25, and NTSYS-PC 2.10e software. ResultA total of 10 pairs of highly polymorphic primers (PIC>0.5) and four pairs of moderately polymorphic primers (0.25<PIC<0.5) were selected. The average number of alleles detected was 3.928 6, and the average Nei's diversity index (H) and Shannon's index (I) were 0.557 8 and 1.002 9, respectively, indicating a high level of genetic diversity. Cluster analysis divided the Pinellia ternata into seven categories, and P. ternata in the same province were in the same categories. The SSR molecular ID cards of 27 P. ternata germplasm were constructed with 14 pairs of primers, and the rapid identification of P. ternata in each region was realized. ConclusionThe results of this study can lay a foundation for the genetic diversity and population structure of P. ternata and provide a scientific basis for the identification of P. ternata germplasm resources, map construction, and molecular-assisted breeding.
RESUMO
@#Objective To investigate the clinical effect of 3D computed tomography bronchial bronchography and angiography (3D-CTBA) and guidance of thoracoscopic anatomic pulmonary segmentectomy by Mimics software system. Methods A retrospective analysis was performed on patients who underwent thoracoscopic segmentectomy in the Department of Thoracic Surgery of Affiliated People's Hospital of Jiangsu University from June 2020 to December 2022. The patients who underwent preoperative 3D-CTBA using Materiaise's interactive medical image control system (Mimics) were selected as an observation group, and the patients who did not receive 3D-CTBA were selected as a control group. The relevant clinical indicators were compared between the two groups. Results A total of 59 patients were included, including 29 males and 30 females, aged 25-79 years. There were 37 patients in the observation group, and 22 patients in the control group. The operation time (163.0±48.7 min vs. 188.8±43.0 min, P=0.044), intraoperative blood loss [10.0 (10.0, 20.0) mL vs. 20.0 (20.0, 35.0) mL, P<0.001], and preoperative puncture localization rate (5.4% vs. 31.8%, P=0.019) in the observation group were better than those in the control group. There was no statistically significant difference in the thoracic tube placement time, thoracic fluid drainage volume, number of intraoperative closure nail bin, postoperative hospital stay, or postoperative air leakage incidence (P>0.05) between the two groups. Conclusion For patients who need to undergo anatomical pulmonary segmentectomy, using Mimics software to produce 3D-CTBA before surgery can help accurately identify pulmonary arteriovenous anatomy, reduce surgical time and intraoperative blood loss, help to determine the location of nodules and reduce invasive localization before surgery, and alleviate patients' pain, which is worthy of clinical promotion.
RESUMO
ObjectiveTo investigate the therapeutic effect of Baihe Wuyaotang (BWT) on non-alcoholic fatty liver disease (NAFLD) and elucidate its underlying mechanism. MethodC57BL/6J mice were randomly assigned to six groups: normal control, model, positive drug (pioglitazone hydrochloride 1.95×10-3 g·kg-1), and low-, medium-, and high-dose BWT (1.3,2.5 and 5.1 g·kg-1). Following a 12-week high-fat diet (HFD) inducement, the mice underwent six weeks of therapeutic intervention with twice-daily drug administration. Body weight was monitored weekly throughout the treatment period. At the fifth week, glucose tolerance (GTT) and insulin tolerance (ITT) tests were conducted. Subsequently, the mice were euthanized for the collection of liver tissue and serum, and the subcutaneous adipose tissue (iWAT) and epididymal adipose tissue (eWAT) were weighed. Serum levels of total triglycerides (TG) and liver function indicators,such as alanine aminotransferase (ALT) and aspartate aminotransferase (AST), were determined. Histological examinations, including oil red O staining, hematoxylin-eosin (HE) staining, Masson staining, and transmission electron microscopy, were performed to evaluate hepatic lipid deposition, pathological morphology, and ultrastructural changes, respectively. Meanwhile, Western blot and real-time quantitative polymerase chain reaction (Real-time PCR) were employed to analyze alterations, at both gene and protein levels, the insulin signaling pathway molecules, including insulin receptor substrate 1/2/protein kinase B/forkhead box gene O1 (IRS1/2/Akt/FoxO1), glycogen synthesis enzymes phosphoenolpyruvate carboxy kinase (Pepck) and glucose-6-phosphatase (G6Pase), lipid metabolism-related genes stearoyl-coA desaturase-1 (SCD-1) and carnitine palmitoyltransferase-1 (CPT-1), fibrosis-associated molecules α-smooth muscle actin (α-SMA), type Ⅰ collagen (CollagenⅠ), and the fibrosis canonical signaling pathway transforming growth factor-β1/drosophila mothers against decapentaplegic protein2/3(TGF-β1/p-Smad/Smad2/3), inflammatory factors such as interleukin(IL)-6, IL-8, IL-11, and IL-1β, autophagy markers LC3B Ⅱ/Ⅰ and p62/SQSTM1, and the expression of mammalian target of rapamycin (mTOR). ResultCompared with the model group, BWT reduced the body weight and liver weight of NAFLD mice(P<0.05, P<0.01), inhibited liver lipid accumulation, and reduced the weight of white fat: it reduced the weight of eWAT and iWAT(P<0.05, P<0.01) as well as the serum TG content(P<0.05, P<0.01). BWT improved the liver function as reflected by the reduced ALT and AST content(P<0.05, P<0.01). It improved liver insulin resistance by upregulating IRS2, p-Akt/Akt, p-FoxO1/FoxO1 expressions(P<0.05). Besides, it improved glucose and lipid metabolism disorders: it reduced fasting blood glucose and postprandial blood glucose(P<0.05, P<0.01), improved GTT and ITT(P<0.05, P<0.01), reduced the expression of Pepck, G6Pase, and SCD-1(P<0.01), and increased the expression of CPT-1(P<0.01). The expressions of α-SMA, Collagen1, and TGF-β1 proteins were down-regulated(P<0.05, P<0.01), while the expression of p-Smad/Smad2/3 was downregulated(P<0.05), suggesting BWT reduced liver fibrosis. BWT inhibited inflammation-related factors as it reduced the gene expression of IL-6, IL-8, IL-11 and IL-1β(P<0.01) and it enhanced autophagy by upregulating LC3B Ⅱ/Ⅰ expression(P<0.05)while downregulating the expression of p62/SQSTM1 and mTOR(P<0.05). ConclusionBWT ameliorates NAFLD by multifaceted improvements, including improving IR and glucose and lipid metabolism, anti-inflammation, anti-fibrosis, and enhancing autophagy. In particular, BWT may enhance liver autophagy by inhibiting the mTOR-mediated signaling pathway.

RESUMO
This paper reports the diagnosis and treatment of a case of lymphocytic hypophysitis in pregnancy complicated by intrahepatic cholestasis of pregnancy. The 32-year-old patient had regular menstrual cycles and conceived naturally. Around 24 weeks of gestation, she developed a headache without abnormalities in the visual field. Skin itching occurred at 32 weeks of gestation, but her headache was significantly relieved. By 33 +1 weeks of pregnancy, the patient experienced elevated total bile acid, transaminase, and hypoglycemia, leading to a diagnosis of intrahepatic cholestasis of gestation (mild). Subsequently, at 33 +6 weeks of gestation, her total bile acid increased substantially, and the disease progressed rapidly into intrahepatic cholestasis of pregnancy (severe). As a result, an emergency cesarean section was performed to terminate the pregnancy. The Apgar score of the newborn was five points at one minute and ten points at five minutes. Following the surgery, the patient showed no lactation and had symptoms such as nausea, vomiting, fatigue, and refractory hyponatremia. Blood hormone measurement showed hypopituitarism. An enhanced intracranial MRI showed pituitary enlargement and uniform enhancement. Consequently, the clinical diagnosis was lymphocytic hypophysitis. Treatment with glucocorticoids effectively alleviated the symptoms. Menstruation resumed after more than one month of delivery. The intracranial MRI in postpartum reexamination after six months of delivery revealed a disappearance of the lesion. The patient continued with oral glucocorticoid therapy.

{L-End}Objective To investigate the current status of long working hours of food-delivery workers from food-delivery platform, and analyze its impact on their health such as occupational stress, depressive symptoms, insomnia symptoms, fatigue accumulation, and life satisfaction. {L-End}Methods A total of 2 145 food-delivery workers from two food-delivery platforms in Guangzhou City were selected as the research subjects using convenience sampling method. The occupational stress, depressive symptoms, insomnia symptoms, fatigue accumulation, and life satisfaction were investigated using the Core Occupational Stress Scale, Patient Health Questionnaire-9 items, Self-sleep Management Questionnaire, Self-diagnosis Questionnaire of Fatigue Accumulation of Workers, and World Health Organization Five-item Well Being Index. {L-End}Results The median and the 25th and 75th percentiles of weekly working hours were 63 (49,77) hours. And 92.2% (1 978/2 145) of workers, who worked more than 40 hours per week, were long working hours workers. While 70.1% (1 504/2 145) workers, who worked 55 hours or more per week, were ultra-long working hours workers. The detection rate of occupational stress, depressive symptoms, insomnia symptoms, fatigue accumulation, and low life satisfaction was 30.1%, 27.5%, 34.7%, 40.8%, and 75.1%, respectively. The longer the weekly working hours of the research subjects, the higher the detection rate of occupational stress and fatigue accumulation (all P<0.01). The results of multivariate logistic regression analysis showed that ultra-long working hours (weekly working hours ≥55 hours) was the influencing factor of occupational stress and fatigue accumulation after excluding the influence of confounding factors among workers (all P<0.05). {L-End}Conclusion The food-delivery workers of food-delivery platforms generally work long hours. Ultra-long working hours is a risk factor for occupational stress and fatigue accumulation among these workers.

RESUMO
Objective:To investigate the clinical value of esophageal-jejunal OrVil TM anas-tomosis and Overlap anastomosis in laparoscopic radical total gastrectomy of adenocarcinoma of esophagogastric junction (AEG). Methods:The retrospective cohort study was conducted. The clinicopathological data of 112 patients with AEG who were admitted to the First Hospital of Jilin University from July 2017 to August 2022 were collected. There were 87 males and 25 females, aged (64±8)years. All 112 patients underwent laparoscopic total gastrectomy and D 2 lymphadenectomy, in which 61 cases with esophageal-jejunal OrVil TM anastomosis were divided into the OrVil TM group, 51 cases with esophageal-jejunal Overlap anastomosis were divided into the Overlap group. Observa-tion indicators: (1) surgical situations; (2) postoperative complications; (3) influencing factors for patients undergoing esophageal-jejunal OrVil TM anastomosis. Measurement data with normal distri-bution were represented as Mean± SD, and comparison between groups was conducted using the independent sample t test. Measurement data with skewed distribution were represented as M( Q1, Q3), and comparison between groups was conducted using the non-parameter test. Count data were described as absolute numbers, and comparison between groups was conducted using the chi-square test or Fisher exact probability. Logistic regression model was used for multivariate analysis. Results:(1) Surgical situations. The esophageal invasion length and tumor diameter was 1.0(0.7,2.0)cm and (6.3±2.7)cm in patients of the OrVil TM group, versus 0.2(0.1,0.5)cm and (4.7±2.2)cm, respectively, in patients of the Overlap group, showing significant differences in the above indicators between the two groups ( Z=?6.14, t=3.26, P<0.05). (2) Postoperative complications. Cases with complications ≥Ⅲa grade of Clavien-Dindo classification, cases with respiratory system complications, cases with hydrothorax were 13, 17, 13 in the OrVil TM group, versus 4, 5, 4 in the Overlap group, showing significant differences in the above indicators between the two groups ( χ2=3.91, 5.74, 3.91, P<0.05). Cases underwent readmission within postoperative 30 days were 3 and 1 in the OrVil TM group and the Overlap group, respectively, and all patients recovered after symptomatic treatment. There were 2 cases died after operation in the OrVil TM group and none of patients died after operation in the Overlap group. (3) Influencing factors for patients undergoing esophageal-jejunal OrVil TM anastomosis. Results of multivariate analysis showed that esophageal invasion length was an independent factor influencing for patients undergoing esophageal-jejunal OrVil TM anastomosis ( odds ratio=8.25, 95% confidence interval as 3.41?19.96, P<0.05). Conclusions:Compared with esophageal-jejunal Overlap anastomosis, choosing the esophageal-jejunal Orvil TM anastomosis during laparoscopic radical total gastrectomy can take benefit to the proximal margin of patients with AEG. However, the ratios of complications ≥ Ⅲa grade of Clavien-Dindo classification, respiratory system complications and hydrothorax associated to OrVil TM anastomosis are relatively increased. Esophageal invasion length is an independent influencing factor for patients undergoing esophageal-jejunal OrVil TM anastomosis.
