Objective: To establish a prenatal non-invasive method for combined detection of fetal ABO, RhD, and RhCE blood group genotypes based on fluorescence quantitative PCR (FQ-PCR) technology, and to evaluate its clinical value in the early prenatal diagnosis of hemolytic disease of the fetus and newborn (HDFN). Methods: A total of 200 high-risk singleton pregnant women who underwent prenatal examinations in our hospital from January 2022 to December 2024 were prospectively enrolled. They were divided into four groups: the ABO incompatibility group (n=100), the RhD incompatibility group (n=50), the RhCE incompatibility group (n=50), and the control group (n=200). FQ-PCR technology was used to detect cell-free fetal DNA (cff-DNA) in maternal plasma, targeting the ABO system (261delG, 796C>A), exons 5/7 of the RHD gene, and the key loci of RhCE system (C/c, E/e). After delivery, the blood group of newborn was verified by serological testing of umbilical cord blood., and the hemolysis panel tests (direct antiglobulin test, free antibody test, and antibody release test) were performed to evaluate the detection consistency and identify high-risk factors. Results: The detection coincidence rates for ABO, RhD, and RhCE blood groups were 98.0% (98/100), 100.0% (50/50), and 96.0% (48/50), respectively. The incidence of HDFN in the ABO incompatibility group was 69.0% (69/100), which is significantly higher than that in the RhD incompatibility group (10.0%, 5/50) and the RhCE incompatibility group (2.0%, 1/50). Multivariate analysis identified maternal blood type O (OR=3.021), maternal RhD-negative (OR=5.253), and maternal age ≥35 years (OR=1.950) as independent risk factors for HDFN (all P<0.05). Conclusion: Prenatal non-invasive combined detection of multiple blood group antigen genotypes can significantly improve the efficiency of early diagnosis of HDFN and provide accurate early warning for high-risk pregnant women.

Objective To analyze dynamic contrast-enhanced MRI (DCE-MRI) radiomic features using machine learning algorithms, and to develop and validate a predictive model for HER-2 status in breast cancer. Methods The DCE-MRI images of 272 treatment-naive female patients with breast cancer between 2020 and 2022 were included in this study. Regions of interest (ROIs) were manually segmented using 3d-Slicer software, and radiomic features were extracted. All patients were randomly divided into training sets or validation sets at a ratio of 4∶1. The least absolute shrinkage and selection operator (LASSO) algorithm was used for feature screening on the training set, followed by the development of predictive models using six machine learning algorithms. Internal cross-validation was performed to compare the performance differences between the models. The best-performing model was selected, trained on the training set, and evaluated on the validation set. Evaluation metrics included area under the curve (AUC), sensitivity, specificity, precision, and recall rate. Results The clinical data of patients in the training set and validation set showed no significant differences. Five features were identified by the LASSO algorithm. With these features, six machine learning models were developed on the training set, and their predictive performance was internally cross-validated using the bagging method. XGBoost model had the highest mean AUC (0.696), followed by RF model (0.690); XGBoost model had the highest mean precision (0.756), followed by LR and RF models. Therefore, XGBoost was the optimal model. An HER-2 predictive model was built using the XGBoost algorithm on the training set and applied to the validation set. The AUC, precision, sensitivity, and specificity of the predictive model on the validation set were calculated, and ROC curves, precision-recall curves, calibration curves, and decision-making curves were plotted. Conclusion This study constructed and evaluated different DCE-MRI radiomics-based machine learning models for predicting HER-2 status in breast cancer. Among them, XGBoost algorithm performed the best and has the potential to become a new non-invasive method for preoperative prediction of HER-2 status, providing reliable evidence for personalized clinical diagnosis and treatment.

[Objective] To evaluate the clinical application value of intrauterine perfusion with platelet-rich plasma (PRP) combined with in vitro fertilization-frozen-thawed embryo transfer (IVF-FET) in patients with chronic endometritis (CE). [Methods] A randomized controlled trial (RCT) was conducted, enrolling 60 CE patients undergoing artificial cycle frozen embryo transfer at our hospital from January 2022 to January 2024. Participants were randomly divided into three groups: Group A (routine frozen embryo transfer, n=20), Group B (routine frozen embryo transfer + one PRP intrauterine perfusion, n=20), and Group C (routine frozen embryo transfer + two PRP intrauterine perfusions, n=20). Endometrial thickness during the transformation and transplantation phases, uterine artery pulsatility index (PI), resistance index (RI), systolic peak velocity/end-diastolic velocity (S/D) ratio during transplantation, serum levels of IL-2, IL-4, IL-6, IL-10, and TNF-α during transplantation, as well as biochemical pregnancy rate, clinical pregnancy rate, live birth rate, and early miscarriage rate were compared across groups. [Results] No significant differences in endometrial thickness were observed among the three groups during the transformation phase (P>0.05). During the transplantation phase, endometrial thickness in Groups C and B was significantly higher than in Group A[9.54 (8.96-10.22) and 8.90 (8.34-9.72) vs 8.37 (7.89-8.75) mm, P<0.05], with Group C showing greater thickness than Group B (Z=3.733, P<0.05). Endometrial thickness in Groups C and B during transplantation was significantly increased compared to their respective transformation phases (Z=2.191, 2.462; P<0.05). Groups C and B exhibited lower PI, RI, and S/D values than Group A[PI:1.87 (1.77-1.97), 1.94 (1.88-2.15) vs 2.43 (2.35-2.49); RI:0.75 (0.73-0.77), 0.78 (0.75-0.81) vs 0.84 (0.83-0.86); S/D:2.61 (2.33-3.42), 3.01 (2.20-3.93) vs 3.72 (3.06-4.49); P<0.05]. Group C demonstrated lower PI and RI than Group B (P<0.05). IL-2 levels in Groups C and B were higher than in Group A[3.88 (2.71-5.01), 3.59 (2.73-4.38) vs 3.16 (2.11-3.25) ng/L, P<0.05], while IL-4, IL-6, IL-10, and TNF-α levels were significantly lower (IL-4: Z=1.428, 2.421; IL-6: Z=1.754, 2.435; IL-10: Z=1.754, 2.854; TNF-α: Z=1.961, 1.765; P<0.05). Group C had lower IL-6 levels than Group B (Z=3.976, P<0.05). Biochemical pregnancy rate, clinical pregnancy rate, and live birth rate in Group C were significantly higher than in Group A (75% vs 40%, 70% vs 35%, 60% vs 20%, P<0.05). No significant differences in early miscarriage rates were observed among the groups (χ²=3.750, P>0.05). [Conclusion] Intrauterine autologous PRP perfusion in CE patients enhances pregnancy and live birth rates, improves pregnancy outcomes post-FET, and demonstrates superior efficacy in endometrial repair and receptivity with two PRP perfusions compared to a single perfusion. This provides a safe and effective therapeutic option for optimizing outcomes in CE patients with prior implantation failure.

BACKGROUND: Temozolomide (TMZ) resistance is a significant challenge in treating glioblastoma (GBM). Collagen remodeling has been shown to be a critical factor for therapy resistance in other cancers. This study aimed to investigate the mechanism of TMZ chemoresistance by GBM cells reprogramming collagens. METHODS: Key extracellular matrix components, including collagens, were examined in paired primary and recurrent GBM samples as well as in TMZ-treated spontaneous and grafted GBM murine models. Human GBM cell lines (U251, TS667) and mouse primary GBM cells were used for in vitro studies. RNA-sequencing analysis, chromatin immunoprecipitation, immunoprecipitation-mass spectrometry, and co-immunoprecipitation assays were conducted to explore the mechanisms involved in collagen accumulation. A series of in vitro and in vivo experiments were designed to assess the role of the collagen regulators prolyl 4-hydroxylase subunit alpha 1 (P4HA1) and yes-associated protein (YAP) in sensitizing GBM cells to TMZ. RESULTS: This study revealed that TMZ exposure significantly elevated collagen type I (COL I) expression in both GBM patients and murine models. Collagen accumulation sustained GBM cell survival under TMZ-induced stress, contributing to enhanced TMZ resistance. Mechanistically, P4HA1 directly binded to and hydroxylated YAP, preventing ubiquitination-mediated YAP degradation. Stabilized YAP robustly drove collagen type I alpha 1 ( COL1A1) transcription, leading to increased collagen deposition. Disruption of the P4HA1-YAP axis effectively reduced COL I deposition, sensitized GBM cells to TMZ, and significantly improved mouse survival. CONCLUSION P4HA1 maintained YAP-mediated COL1A1 transcription, leading to collagen accumulation and promoting chemoresistance in GBM.

Objective:To explore the clinical values of carcinoembryonic antigen (CEA), carbohydrate antigen 125 (CA125), carbohydrate antigen 199 (CA199), carbohydrate antigen 724 (CA724) and gastrin 17 (G-17) detections in the early diagnosis of gastric cancer patients.Methods:A retrospective case-control study was conducted. A total of 120 patients with gastric diseases who were admitted to General Hospital of Xuzhou Mining Group from January 2019 to December 2021 were selected. According to the pathological results of gastroscopy examination, the patients were divided into gastric ulcer group (23 cases), atrophic gastritis group (58 cases) and early gastric cancer group (39 cases). The healthy control group consisted of 30 healthy individuals who underwent physical examination during the same period. All participants were detected for serum levels of CEA, CA125, CA199, CA724, and G-17. The levels of various indicators in each group were compared. Using the pathological results of gastroscopy as the gold standard, the receiver operating characteristic (ROC) curve was used to analyze the efficacy of various indicators in distinguishing early gastric cancer from healthy individuals, gastric ulcer and atrophic gastritis.Results:The serum levels of CA125 [ M ( Q1, Q3)] [19.94 (8.29, 22.99) U/ml vs. 6.03 (4.07, 10.48) U/ml, 7.49 (4.96, 12.19) U/ml, 7.54 (6.20, 11.91) U/ml], CA199 [32.09 (15.68, 41.97) U/ml vs. 19.19 (10.01, 30.05) U/ml, 21.00(16.01, 32.71) U/ml, 18.95 (13.90, 32.76) U/ml], CA724 [19.55 (3.91, 26.25) U/ml vs. 4.61 (3.06, 5.24) U/ml, 4.09 (3.37, 5.00) U/ml, 4.88 (3.92, 5.46) U/ml] and G-17 [21.01 (14.67, 24.00) pmol/L vs. 11.80 (10.07, 16.58) pmol/L, 12.74 (11.09, 14.69) pmol/L, 12.08 (8.40, 15.10) pmol/L] in the early gastric cancer group were higher than those in the gastric ulcer group, atrophic gastritis group and healthy control group, and the differences were statistically significant (all P < 0.05). The CEA level in the early gastric cancer group, gastric ulcer group and atrophic gastritis group was all higher than that in the healthy control group [4.38 (3.22, 7.56) ng/ml, 4.51 (3.37, 5.51) ng/ml, 4.49 (4.13, 5.09) ng/ml vs. 3.95 (2.16, 4.44) ng/ml], and the differences were statistically significant (all P < 0.05). ROC curve analysis showed that among all indicators, the area under the curve (AUC) of G-17 for distinguishing early gastric cancer from healthy individuals was the largest [0.825 (95% CI: 0.728-0.922)], the optimal critical value was 18.21 pmol/L, and the specificity was the highest (96.7%); the AUC of CA125 and CA724 was also relatively high, with values of 0.768 (95% CI: 0.653-0.884) and 0.744 (95% CI: 0.622-0.866), respectively, and the optimal critical values were 15.41 and 39.60 U/ml, respectively, with the corresponding sensitivities of 71.8%, which was the highest among several indicators. Among all indicators, CA125 had the largest AUC for distinguishing early gastric cancer from gastric ulcer, which was 0.829 (95% CI: 0.729-0.930), with an optimal critical value of 11.60 U/ml, and the corresponding sensitivity was also the highest (74.4%); the AUC of CEA and CA724 was 0.534 (0.391-0.677) and 0.786 (0.668-0.903), respectively; the optimal critical values were 7.20 ng/ml and 6.34 U/ml, respectively; the corresponding specificity was 100.0%. Among the various indicators, the AUC of G-17 for distinguishing early gastric cancer from atrophic gastritis was the largest [0.813 (95% CI: 0.710-0.915)]. The specificity of each indicator at the optimal critical value was relatively high (≥ 94.8%), among which the optimal critical values of CEA and CA125 were 7.170 ng/ml and 15.55 U/ml, respectively, with the corresponding specificity of 100.0%; the AUC of CA724 was 0.783 (95% CI: 0.671-0.895), the optimal critical value was 6.40 U/ml, and the corresponding sensitivity was 71.8%, which was the highest among the several indicators. Conclusions:CEA, CA125, CA199, CA724, and G-17 have high sensitivity and detection rate in the differential diagnosis of early gastric cancer, gastric ulcer and atrophic gastritis, and have certain clinical values in the diagnosis of early gastric cancer and potential for clinical auxiliary diagnosis.

Objective:To analyze the influencing factors of mood state of common rheumatic (rheumatoid arthritis; systemic lupus erythematosus; ankylosing spondylitis) patients and find out the common characteristics of patients with negative emotions, so as to identify and treat rheumatic patients with anxiety and depression in clinical practice.Methods:A total of 205 patients with rheumatism (83 with rheumatoid arthritis, 74 with systemic lupus erythematosus, 48 with ankylosing spondylitis) admitted to the Shandong Provincial Hospital Affiliated to Shandong University from April to May 2023 were included. The general condition and POMS of patients were collected. All patients were divided into 3 groups of low-TMD/ middle-TMD/ high-TMD(TMD≤90 scores; 90 scores105 scores). The χ2 test was used for categorical variables, and the continuous variables were tested for normal distribution. If they followed a normal distribution, the independent sample t test (for homogeneous variance) or the Welch′s t test (for unequal variance) was used for comparison between the two groups, and one-way analysis of variance was used for comparison between multiple groups; if they did not follow a normal distribution, the Kruskal-Wallis H test was used for comparison between groups. Patients with TMD>90 scores were defined as the negative emotion group. Gender, age, education level, economic income status, and TMD were included in the two-step cluster analysis (TCA) to obtain three cluster groups and analyze the differences between the groups. Logistic regression was used to analyze the risk factors. Results:The study found that patients with rheumatic diseases with low serum albumin levels ( F=6.26, P=0.003), low education level ( χ2=8.36, P=0.015), low economic level ( χ2=15.59, P<0.001), short disease course ( H=28.01, P<0.001), and high disease activity ( χ2=56.93, P<0.001) had higher TMD scores, which was not related to the type of disease ( χ2=4.81, P=0.090). The negative mood group had a higher proportion of females (57.6% vs. 73.4%, χ2=5.16, P=0.023), a shorter course of disease [24(12, 48) months vs. 48(24, 93) months, Z=13.58, P<0.001], and a lower serum albumin [(42.2±4.0) g/L vs. (44.0±3.4)g/L, t=-14.09, P=0.002], low level of education ( χ2=9.04, P=0.029), low level of income ( χ2=10.29, P=0.036), high disease activity ( χ2=61.91, P<0.001). The results of cluster analysis indicated that the above factors were significantly different among the three cluster groups except the course of disease. It is noteworthy that age ( F=19.25, P<0.001) and serum albumin ( F=5.64, P=0.004) had the lowest value and the highest TMD score ( F=5.64, P<0.001). Regression analysis showed that gender, disease course and disease activity were related factors to the occurrence of negative emotions, and high disease activity was a risk factor [ OR(95% CI) =26.58(4.53, 156.09), P<0.001]. Men [ OR(95% CI)=0.20 (0.08, 0.50), P=0.001) and the course of [ OR(95% CI)=0.99 (0.98, 1.00), P=0.007) as the protective factors. Conclusion:Male, serum albumin level, education level, income level, disease course and disease activity were the main factors affecting the mood state of patients with rheumatism, in which high disease activity was the risk factor, male and long disease course were the protective factors.

To explore the impacts of TGR5 on liver lipid metabolism and bile acid synthesis in dairy cows with fatty liver.Liver tissues of healthy cows and cows with fatty liver were collected through puncture technique.The protein and mRNA expressions of lipid synthesis-related factors ACC1,FAS,SREBF1,lipid oxidation factor CPT1A,and bile acid synthesis-related factors CYP8B1,CYP7B1,CYP27A1 were detected by Western blot and fluorescent quantitative PCR.Moreover,the mRNA levels of CYP7B1 were determined.Primary hepatocytes of 1-day-old calves were extracted and cultured in vitro,and four treatment groups were established,namely Control,NEFA,INT-777,and the INT-777+NEFA group.The concentration of NEFA group was 1.2 mmol/L,the con-centration of INT-777 group was 1 μmol/L,and the concentration of INT-777+NEFA group was 1.2 mmol/L NEFA and 1 μmol/L INT-777 simultaneously.After 12 h of stimulation,cells were collected,and the protein and mRNA levels of ACC1,FAS,SREBF1,CPT1A,CYP8B1,CYP7A1,CYP27A1,and the mRNA levels of CYP7B1 were detected by Western blot and fluorescent quanti-tative PCR.The content of lipid droplets and TG in the cells were detected by flow cytometry and kit.The results demonstrated that compared with healthy cows,the protein and mRNA expressions of ACC1,FAS,SREBF1,CYP8B1,and CYP7A1 in the liver tissues of fatty liver cows were upreg-ulated,while the protein and mRNA levels of CPT1 A,CYP27A1,TGR5,and the mRNA levels of CYP7B1 were downregulated.In vitro experiments revealed that compared with the Control group,the protein and mRNA levels of ACC1,FAS,SREBF1,CYP8B1,and CYP7A1 in the NEFA group were upregulated,and the protein and mRNA levels of CPT1A,CYP27A1,and TGR5,as well as the mRNA level of CYP7B1,were downregulated.Compared with the NEFA group,the protein and mRNA levels of ACC1,FAS,SREBF1,CYP8B1,CYP7A1 were downregulated in the INT-777+NEFA group,while the protein and mRNA levels of CPT1A CYP27A1,and TGR5 as well as the mRNA level of CYP7B1,were upregulated.The results of flow cytometry and the kit indicated that the lipid droplets and TG content in the NEFA group were upregulated compared with the Control group,while the lipid droplets and TG content in the INT-777+NEFA group were downregulated compared with the NEFA group.The above results suggested that the addition of TGR5 agonist promoted the expression of TGR5 and ameliorated the abnormal lipid metabolism and bile acid synthesis in the liver of dairy cows with fatty liver.

Objective::To analyze fetal renal abnormality genetic features and the prenatal characteristics of the 17q12 microdeletion syndrome.Methods::This prospective cohort study examined prenatal ultrasound findings of renal abnormalities in pregnant women who underwent single nucleotide polymorphism (SNP) array or copy number variation sequencing (CNV-seq) testing on amniotic fluid or fetal tissue at Tianjin Central Obstetrics and Gynecology Hospital between January 2016 and August 2022. The study cohort comprised women with advanced maternal age, fetal ultrasound anomalies, high-risk non-invasive prenatal testing results, or suspected 17q12 microdeletion syndrome. Comprehensive clinical data, including maternal age, detailed ultrasound findings, and pregnancy outcomes, were systematically collected. SNP-array analysis was conducted using an Affymetrix CytoScan 750 K Array Chip to identify CNVs and loss of heterozygosity, while CNV-seq was performed on the Illumina HiSeq 2000 platform. Detected variants were classified according to the American College of Medical Genetics and Genomics guidelines. Statistical analyses were performed using SPSS version 27.0.Results::Abnormal renal development was identified in 141 patients, among whom 26 exhibited hyperechogenic kidneys (HCK). Of these, 12 cases were associated with 17q12 microdeletion syndrome, while the remaining 14 were linked to other chromosomal abnormalities. When excluding patients with HCK, those diagnosed with polycystic kidney disease demonstrated a higher prevalence of chromosomal abnormalities compared to those with multicystic dysplastic kidney and renal dysplasia. Although isolated conditions such as horseshoe kidney, hydronephrosis, ectopic kidney, and unilateral kidney typically presented with normal chromosomal findings, the incidence of chromosomal abnormalities increased when these conditions coexisted with other anomalies. A detailed analysis of the correlation between 17q12 microdeletion syndrome and HCK revealed that 12 out of the 14 patients diagnosed with 17q12 microdeletion syndrome exhibited HCK. Genetic testing confirmed the syndrome in seven patients, with five cases attributed to novel mutations and two cases resulting from inherited mutations.Conclusion::Fetal HCK was closely associated with the 17q12 microdeletion syndrome, and polycystic kidney disease showed a higher rate of chromosomal abnormalities. Chromosome test results were mostly normal in patients with other renal abnormalities, such as kidney dysplasia, horseshoe kidneys, hydronephrosis, kidney deficiency, and ectopic kidneys. Prenatal diagnosis is recommended, especially in cases of non-isolated fetal renal abnormalities. This study provides strong evidence supporting a link between fetal renal abnormalities and genetic syndromes.

The purpose of this study was to investigate the effect of medium-chain fatty acids(MC-FAs)caprylic acid(C8∶0)on lipid metabolism of calf hepatocytes.Primary calf hepatocytes were extracted and cultured,and 1.2 mmol/L nonesterified fatty acids(NEFAs)were added to the hep-atocytes to construct a model of hepatic lipid deposition in primary calf hepatocytes,Five process-ing groups have been set up:Control group(Ctrl),NEFA added group(NEFA),C8∶0 1.2 mmol/L treatment group(C8∶0 1.2),NEFA+C8∶0 0.2 mmol/L treatment group(NEFA+C8∶00.2),C8∶0 0.2 mmol/L treatment group(C8∶0 0.2).Stimulate calf liver cells for 12 hours,and the levels of triglyceride(TG),lipid oxidation(MDA),hydrogen peroxide(H2O2)and total SOD activity were detected by biochemical kit,and FAS,a protein related to lipid synthesis,was detec-ted by Western blot.The results showed that compared with the control group,the concentrations of TG,MDA and H2O2 in NEFA group increased significantly(P＜0.01),and the activity of SOD decreased significantly(P＜0.05).The protein expression levels of FAS,ACC1,DGAT2 and SREBP-1C were significantly up-regulated(P＜0.01),while the expression level of CPT1A was significantly down-regulated(P＜0.01).Compared with the NEFA group,the protein expression levels of SREBP-1C and DGAT2 in the NEFA+C8∶0(concentration 0.2 mmol/L)group de-creased significantly(P＜0.05),and the protein expression level of fatty acid β-oxidation related molecule CPT1A was slightly higher than that in the NEFA group,but there was no statistical sig-nificance(P＞0.05),and the MDA level in hepatocytes decreased significantly(P＜0.05).In a word,the results of this study show that C8∶0 has antioxidant effect,which can effectively reduce the liver injury caused by oxidative stress,regulate the expression of liver fat gene,and then pro-tect liver injury.
