Objective:To explore the distant metastatic characteristics of metastatic hormone-sensitive prostate cancer (mHSPC) and metastatic castration-resistant prostate cancer (mCRPC) based on prostate-specific membrane antigen (PSMA) PET-CT.Methods:This is a retrospective cohort study. Ultimately, data from 227 patients with metastatic prostate cancer who underwent PSMA PET-CT examinations at Xiangya Hospital, Central South University between March 2016 and May 2025 were retrospectively reviewed, including 117 mHSPC patients with an age of (68.8±7.6) years (range:53 to 89 years) and 110 mCRPC patients with an age of (69.4±7.5) years (range: 49 to 88 years). Clinical and pathological data, along with metastatic characteristics identified via PSMA PET-CT, were collected and compared. Intergroup comparisons were performed using χ 2 tests. Results:The incidence rates of lymph node metastasis, bone metastasis, and visceral metastasis in the mHSPC group were 71.8% (84/117), 89.7% (105/117), and 11.1% (13/117), respectively, while those in the mCRPC group were 52.7% (58/110), 91.8% (101/110), and 15.5% (17/110), respectively. The incidence of lymph node metastasis in the mHSPC group was significantly higher than that in the mCRPC group ( χ2=8.800, P=0.003). Among patients with bone metastasis, the rates of osteoblastic metastasis, osteolytic metastasis, and mixed metastasis in the mHSPC group were 76.2% (80/105), 8.6% (9/105), and 15.2% (16/105), respectively, while the corresponding rates in the mCRPC group were 74.3% (75/101), 7.3% (8/101), and 16.4% (18/101), respectively, all indicating a relatively high probability of osteolytic and mixed bone metastases ( χ2=0.260, P=0.878). Among patients with mHSPC and mCRPC who tested positive for visceral metastasis, lung metastasis (9/13 and 8/17) and liver metastasis (4/13 and 9/17) were the most common sites of metastasis, but there was no significant difference in the composition of visceral metastasis between the two groups ( χ2=0.933, P=0.564). In this study, among 20 patients who progressed from mHSPC to mCRPC, 35.0% (7/20) had persistent or progressive activity at the original metastatic site, 35.0% (7/20) developed new metastatic lesions, and 30.0% (6/20) showed inhibitory changes in the original metastatic lesions. Among patients with imaging progression, 1/14 of patients with osteoblastic metastatic lesions at the mHSPC stage exhibited osteolytic changes upon progression to mCRPC. Conclusion:Compared with the mCRPC group, the mHSPC group has a higher lymph node metastasis rate,and both groups have common rates of osteolytic and mixed bone metastases and visceral metastasis.

Objective:To compare the diagnostic efficacy of 68Ga-prostate-specific membrane antigen (PSMA)-617 PET/CT and multiparametric magnetic resonance imaging (mpMRI) in detecting extraprostatic extension (EPE) and seminal vesicle invasion (SVI) in prostate cancer. Methods:A retrospective analysis was conducted on the clinical data of 113 patients with localized prostate cancer who underwent both 68Ga-PSMA-617 PET/CT and mpMRI at Xiangya Hospital, Central South University, from May 2018 to May 2024 prior to radical prostatectomy (RP). The median age of the patients was 66.0 (61.3, 71.0) years old, with a median body mass index of 28.86 (19.01, 24.77) kg/m 2, and a median prostate-specific antigen (PSA) level of 13.50(9.26, 21.99) ng/ml. The pathological results after RP were used as the gold standard to compare the sensitivity, specificity, positive predictive value, and negative predictive value of the two imaging modalities in diagnosing EPE and SVI. Additionally, the diagnostic value of combining both imaging modalities was explored, employing a parallel strategy where a positive result from either modality was deemed positive, and only when both tests were negative was the result considered negative. Results:Pathological results after RP indicated EPE in 46 cases (40.71%) and SVI in 11 cases (9.70%). In diagnosing EPE, the sensitivity, specificity, positive predictive value, and negative predictive value of 68Ga-PSMA-617 PET/CT were 17.39% (8/46), 97.01% (65/67), 80.00% (8/10), and 63.11% (65/103), respectively, while for mpMRI they were 34.78% (16/46), 83.58% (56/67), 59.26% (16/27), and 65.12% (56/86), respectively. The sensitivity of mpMRI was significantly higher than that of 68Ga-PSMA-617 PET/CT ( P=0.048), while the specificity was the opposite ( P=0.008). When combining both imaging modalities, the sensitivity, specificity, positive predictive value, and negative predictive value were 45.65% (21/46), 80.60% (54/67), 61.76% (21/34), and 68.35% (54/79), respectively. In diagnosing SVI, the sensitivity, specificity, positive predictive value, and negative predictive value of 68Ga-PSMA-617 PET/CT were 27.27% (3/11), 96.08% (98/102), 42.86% (3/7), and 92.45% (98/106), respectively, while for mpMRI they were 36.36% (4/11), 88.24% (90/102), 25.00% (4/16), and 92.78% (90/97), respectively. The specificity of 68Ga-PSMA-617 PET/CT was significantly higher than that of mpMRI ( P=0.033). When combining both imaging modalities, the sensitivity, specificity, positive predictive value, and negative predictive value were 45.45% (5/11), 85.29% (87/102), 25.00% (5/20), and 93.55% (87/93), respectively. Conclusions:mpMRI has higher sensitivity in diagnosing EPE and SVI in prostate cancer, while 68Ga-PSMA-617 PET/CT shows higher specificity. The combined use of both imaging modalities can increase diagnostic sensitivity but may reduce specificity. PSMA PET/MRI may be a more accurate diagnostic tool for discerning EPE and SVI.

Objective:To investigate the clinical efficacy of vitamin D as an adjunct to low-dose aspirin on patients with early-onset severe preeclampsia.Methods:A retrospective analysis was conducted on the clinical data of 102 patients with early-onset severe preeclampsia admitted to Zhoushan Women and Children's Hospital from January 2020 to January 2024. Fifty patients admitted for treatment from January 2020 to January 2022 were included in the control group and received low-dose aspirin treatment. Fifty-two patients admitted between February 2022 and January 2024 were included in the observation group and received vitamin D as an adjunct to low-dose aspirin treatment. Both groups were treated for 7 days. Blood pressure, homocysteine, serum 25-hydroxyvitamin D 3, renal function indicators (glomerular filtration rate, 24-hour urine protein quantification), coagulation function indicators (prothrombin time, thrombin time, D-dimer, activated partial thromboplastin time), and pregnancy outcomes were compared between the two groups. Results:After treatment, systolic blood pressure, diastolic blood pressure, homocysteine, 24-hour urine protein quantification, and D-dimer in the observation group were (134.33 ± 6.28) mmHg (1 mmHg = 0.133 kPa), (88.57 ± 5.76) mmHg, (10.65 ± 3.15) μmol/L, (0.59 ± 0.31) g/24 hours, and (0.51 ± 0.32) mg/L, respectively. These values were significantly lower than those in the control group [(142.28 ± 6.04) mmHg, (93.85 ± 5.38) mmHg, (13.15 ± 2.89) μmol/L, (1.28 ± 0.47) g/24 hours, and (0.73 ± 0.49) mg/L, t = 4.17, -10.37, 4.17, 8.79, 2.69, all P < 0.05]. In the observation group, serum 25-hydroxyvitamin D 3 level and glomerular filtration rate were (27.94 ± 6.43) μg/L and (98.65 ± 14.72) mL·min?1·1.73 m?2, respectively. These values were significantly higher than those in the control group [(15.24 ± 5.92) μg/L, (90.19 ± 12.07) mL·min?1·1.73 m?2 ( t = -10.37, -3.18, both P < 0.05). Additionally, in the observation group, prothrombin time, thrombin time, and activated partial thromboplastin time were (12.19 ± 0.53) seconds, (12.19 ± 0.53) seconds, and (0.51 ± 0.32) seconds, respectively. These times were significantly shorter than those in the control group [(13.22 ± 1.15) seconds, (16.94 ± 2.07) seconds, and (34.21 ± 3.93) seconds ( t = 5.85, 4.27, 3.81, all P < 0.05). There was no statistically significant difference in incidence of pregnancy outcomes between the two groups ( P > 0.05). Conclusions:Vitamin D as an adjunct to low-dose aspirin for the treatment of early-onset severe preeclampsia significantly reduces blood pressure, enhances blood circulation, promotes metabolism, improves coagulation function, and aids in the recovery of renal function in patients.

Objective:To evaluate the efficacy and safety of nebulized inhalation of recombinant human interferon (IFN) α1b injection in the treatment of respiratory syncytial virus (RSV) associated lower respiratory tract infections (pneumonia and bronchiolitis) in children.Methods:A randomized, double-blind, parallel, placebo-controlled add-on design was used.Children with pneumonia or bronchiolitis aged 2 months to 5 years who tested positive for RSV antigen within 72 hours of onset from 30 clinical trial sites including Beijing Children′s Hospital, Capital Medical University between February 2021 and December 2022 were included in this study and randomly divided into 2 groups at a ratio of 1∶1 based on a stratified-block method.Both groups received basic treatments such as cough control, asthma relieving, expectorant treatment, fever reduction, oxygen therapy, etc.The experimental group received additional nebulized inhalation of IFN α1b injection at a dose of 2.0 μg/(kg·time), twice a day.The control group received nebulized inhalation of placebo twice a day.Clinical efficacy was evaluated based on indicators such as the duration of clinical symptoms and signs, and the Kaplan-Meier method was used to calculate the median and 95% CI of the duration of clinical symptoms and signs.The Log-rank test was used to compared data between groups.Safety was assessed through the incidence of adverse reactions and laboratory tests, and the Chi-square test was used to analyze the difference between groups. Results:There were 123 children in the experimental group and 122 children in the control group.The median durations of all the 5 clinical symptoms and signs [including shortness of breath, wheezing, dyspnea (visible retractions), decreased transcutaneous oxygen saturation, and abnormal mental state] in the experimental group after treatment were slightly shortened than those in the control group [2.7 d(95% CI: 1.9-3.0 d)] vs.[2.9 d(95% CI: 2.6-3.6 d), P=0.027].The improvement in dyspnea (retractions) was especially pronounced in the experimental group, with a relief rate of 50.0% (0, 100%) on the first day of administration[compared with 0 (0, 50.0%) in the control group ( Z=2.002, P=0.025)].The median duration of dyspnea in the experimental group was nearly 1 day shorter than that in the control group [1.0 d(95% CI: 0.7-1.7 d) vs.1.8 d(95% CI: 1.0-2.5 d), P=0.046].There were no significant difference in hospital stay [6.0(5.0, 8.0) d vs.6.5(5.0, 8.0) d, Z=0.675, P=0.500], oxygen therapy duration [32.0(14.0, 96.3) h vs.39.0 (24.0, 83.2) h, Z=0.094, P=0.925], the recovery rate from clinical symptoms during treatment [(105/106, 99.1%) vs.(96/101, 95.0%)], and recurrence rate [(0/106, 0) vs.(2/101, 2.0%)] between the 2 groups (all P>0.05).However, the above-mentioned four indicators in the experimental group showed a trend of clinical benefits.The quantitative virus detection results showed that the RSV viral load in both groups decreased after treatment compared to before treatment.After 2 days of treatment, the decline rate of RSV viral load from the baseline was 0.90 lg copies/(mL·d) in the experimental group and 0.25 lg copies/(mL·d)in the control group, with a statistically significant difference ( P<0.05).Furthermore, there was no statistically significant difference in the incidence of adverse reactions between the 2 groups ( P>0.05).Importantly, no drug-related serious adverse reactions occurred in both groups. Conclusions:The nebulized inhalation therapy of IFN α1b demonstrates efficacy and safety in treating pediatric RSV associated lower respiratory tract infections.It particularly offers outstanding clinical therapeutic value for severe children.

ObjectiveTo explore the effect of serum containing Zhenwutang on myocardial mast cell apoptosis induced by angiotensin Ⅱ （AngⅡ） and the mechanism of the correlation between apoptosis and mitochondrial autophagy. MethodsIn this experiment， AngⅡ and serum containing Zhenwutang with different concentrations were used to interfere with H9C2 cardiomyocytes for 24 h， and the survival rate of H9C2 cardiomyocytes was detected by cell counting kit-8 （CCK-8） to screen the optimal concentration for the experiment. Enzyme-linked immunosorbent assay （ELISA） was used to detect the content of B-type natriuretic peptide （BNP） in cell culture supernatant， and immunofluorescence was used to detect the cell surface area to verify the construction of the myocardial mast cell model. Subsequently， the experiment was divided into a blank group （20% blank serum）， a model group （20% blank serum + 5×10^-5 mol·L^-1 AngⅡ）， low-， medium-， and high-dose （5%， 10% and 20%） serum containing Zhenwutang groups， an autophagy inhibitor group （1×10^-4 mol·L^-1 3-MA）， and autophagy inducer group （1×10^-7 mol·L^-1 rapamycin）. The apoptosis level of H9C2 cells and the changes of mitochondrial membrane potential were detected by flow cytometry. The lysosomal probe （Lyso Tracker） and mitochondrial probe （Mito Tracker） co-localization was employed to detect autophagy. Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR） was used to detect Caspase-3， Caspase-9， B-cell lymphoma 2 （Bcl-2）， Bcl-2-related X protein （Bax）， and cytochrome C （Cyt C） in apoptosis-related pathways and the relative mRNA expression of ubiquitin ligase （Parkin）， phosphatase and tensin homolog （PTEN）-induced kinase 1 （PINK1）， and p62 protein in mitochondrial autophagy-related pathways. Western blot was used to detect cleaved Caspase-3， cleaved Caspase-9， Bax， Bcl-2， and Cyt C in apoptosis-related pathways， phosphorylated ubiquitin ligase （p-Parkin）， phosphorylated PTEN-induced kinase 1 （p-PINK1）， p62， and Bcl-2 homology domain protein Beclin1 in mitochondrial autophagy-related pathways， and the change of microtubule-associated protein 1 light chain 3 （LC3） Ⅱ/Ⅰ ratio. ResultsCCK-8 showed that when the concentration of AngⅡ was 5×10^-5 mol·L^-1， the cell activity was the lowest， and there was no cytotoxicity. At this concentration， the surface area of cardiomyocytes was significantly increased （P<0.01）， and the content of BNP in the supernatant of culture medium was significantly increased （P<0.05）. Therefore， AngⅡ with a concentration of 5×10^-5 mol·L^-1 was selected for the subsequent modeling of myocardial mast cells. Compared with the blank group， the model group and the autophagy inhibitor 3-MA group had a significantly increased apoptosis rate （P<0.01） and significantly decreased mitochondrial membrane potential （P<0.01）. The results of immunofluorescence co-localization showed that compared with the blank group， the model group had a significantly decreased number of red and green fluorescence spots. The results of Real-time PCR showed that compared with that in the blank group， the relative mRNA expression of Bax， Caspase-3， Caspase-9， Cyt C， and p62 in the model group was significantly up-regulated （P<0.01）， while the relative mRNA expression of Bcl-2， Parkin， and PINK1 was significantly down-regulated （P<0.01）. In addition， the relative protein expression of Bax， cleaved Caspase-3， cleaved Caspase-9， Cyt C， and p62 was significantly up-regulated （P<0.01）. The LC3Ⅱ/Ⅰ was significantly decreased， and the relative protein expression of Bcl-2， p-Parkin， p-PINK1， and Beclin1 was significantly down-regulated （P<0.01）. Compared with the model group， the serum containing Zhenwutang groups and the autophagy inducer group had significantly decreased apoptosis rate （P<0.01）， and the decrease ratio of mitochondrial membrane potential is significantly lowered （P<0.01） in a dose-dependent manner. Additionally， both red and green fluorescence spots became more in these groups. In the 3-MA group， the number of red and green fluorescence spots decreased significantly. The relative mRNA expression of Bax， Caspase-3， Caspase-9， Cyt C， and p62 was significantly down-regulated （P<0.05， P<0.01）， while that of Bcl-2， Parkin， and PINK1 was significantly up-regulated （P<0.01）. In the serum containing Zhenwutang groups， the relative protein expression levels of Bax， cleaved Caspase-3， cleaved Caspase-9， Cyt C， and p62 were significantly down-regulated （P<0.05，P<0.01）. The LC3Ⅱ/Ⅰ was significantly increased， and the relative protein expression levels of Bcl-2， p-Parkin， p-PINK1， and Beclin1 were significantly up-regulated （P<0.01）. ConclusionThe serum containing Zhenwutang can reduce the apoptosis of myocardial mast cells and increase mitochondrial autophagy. This is related to the inhibition of intracellular Bax/Bcl-2/Caspase-3 apoptosis pathway and regulation of Parkin/PINK1 mitochondrial autophagy pathway.

Objective:To compare the diagnostic efficacy of 68Ga-prostate-specific membrane antigen (PSMA)-617 PET/CT and multiparametric magnetic resonance imaging (mpMRI) in detecting extraprostatic extension (EPE) and seminal vesicle invasion (SVI) in prostate cancer. Methods:A retrospective analysis was conducted on the clinical data of 113 patients with localized prostate cancer who underwent both 68Ga-PSMA-617 PET/CT and mpMRI at Xiangya Hospital, Central South University, from May 2018 to May 2024 prior to radical prostatectomy (RP).

Additionally, the diagnostic value of combining both imaging modalities was explored, employing a parallel strategy where a positive result from either modality was deemed positive, and only when both tests were negative was the result considered negative. Results:Pathological results after RP indicated EPE in 46 cases (40.71%) and SVI in 11 cases (9.70%). In diagnosing EPE, the sensitivity, specificity, positive predictive value, and negative predictive value of 68Ga-PSMA-617 PET/CT were 17.39% (8/46), 97.01% (65/67), 80.00% (8/10), and 63.11% (65/103), respectively, while for mpMRI they were 34.78% (16/46), 83.58% (56/67), 59.26% (16/27), and 65.12% (56/86), respectively. The sensitivity of mpMRI was significantly higher than that of 68Ga-PSMA-617 PET/CT ( P=0.048), while the specificity was the opposite ( P=0.008). When combining both imaging modalities, the sensitivity, specificity, positive predictive value, and negative predictive value were 45.65% (21/46), 80.60% (54/67), 61.76% (21/34), and 68.35% (54/79), respectively. In diagnosing SVI, the sensitivity, specificity, positive predictive value, and negative predictive value of 68Ga-PSMA-617 PET/CT were 27.27% (3/11), 96.08% (98/102), 42.86% (3/7), and 92.45% (98/106), respectively, while for mpMRI they were 36.36% (4/11), 88.24% (90/102), 25.00% (4/16), and 92.78% (90/97), respectively. The specificity of 68Ga-PSMA-617 PET/CT was significantly higher than that of mpMRI ( P=0.033). When combining both imaging modalities, the sensitivity, specificity, positive predictive value, and negative predictive value were 45.45% (5/11), 85.29% (87/102), 25.00% (5/20), and 93.55% (87/93), respectively. Conclusions:mpMRI has higher sensitivity in diagnosing EPE and SVI in prostate cancer, while 68Ga-PSMA-617 PET/CT shows higher specificity. The combined use of both imaging modalities can increase diagnostic sensitivity but may reduce specificity. PSMA PET/MRI may be a more accurate diagnostic tool for discerning EPE and SVI.

OBJECTIVES: Investigating the protective effect of naringenin (NAR) on the osteogenic potential of human periodontal ligament stem cells (hPDLSCs) under oxidative stress and its related mechanisms. METHODS: The oxidative damage model of hPDLSCs was established using hydrogen peroxide (H₂O₂) andthe hPDLSCs were treated with different concentrations of NAR and 0.5 μmol/L forkhead box protein O-1 (FOXO1) inhibitor AS1842856. After that, the cell counting kit-8 (CCK8) was used to determine the optimal concentrations of H₂O₂ and NAR. The alkaline phosphatase (ALP) staining and real time fluorescent quantitative reverse transcription polymerase chain reaction (qRT-PCR) were employed to assess the expression of ALP, runt-related transcription factor 2 (RUNX2) and osteocalcin (OCN) in hPDLSCs of each group. The enzyme-linked immunosorbent assay (ELISA) and 2',7'-dichlorofluorescin diacetate (DCFH-DA) staining were utilized to evaluate the expression of reactive oxygen species (ROS), malondialdehyde (MDA) and lactate dehydrogenase (LDH) in hPDLSCs. Meanwhile, qRT-PCR and western blot were used to detect the expression levels of FOXO1 and β-catenin, both are pathway related genes and proteins. RESULTS: H₂O₂ exposure led to an increase in oxidative damage in hPDLSCs, characterized by a rise in intracellular ROS levels and increased expression of MDA and LDH (P<0.05). At the same time, the osteogenic differentiation ability of hPDLSCs decreased, as evidenced by lighter ALP staining and reduced expression levels of osteogenic differentiation-related genes ALP, RUNX2 and OCN (P<0.05). Co-treatment with NAR alleviated the oxidative damage in hPDLSCs, enhanced their antioxidant capacity, and restored their osteogenic ability. The FOXO1 inhibitor AS1842856 downregulated the expression of β-catenin (P<0.05) and significantly diminished both the antioxidant effect of NAR and its ability to restore osteogenesis (P<0.05). CONCLUSIONS NAR can enhance the antioxidant capacity of hPDLSCs by activating the FOXO1/β-catenin signaling pathway within hPDLSCs, thereby mitigating oxidative stress damage and alleviating the loss of osteogenic capacity.

Objective:To explore the distant metastatic characteristics of metastatic hormone-sensitive prostate cancer (mHSPC) and metastatic castration-resistant prostate cancer (mCRPC) based on prostate-specific membrane antigen (PSMA) PET-CT.Methods:This is a retrospective cohort study. Ultimately, data from 227 patients with metastatic prostate cancer who underwent PSMA PET-CT examinations at Xiangya Hospital, Central South University between March 2016 and May 2025 were retrospectively reviewed, including 117 mHSPC patients with an age of (68.8±7.6) years (range:53 to 89 years) and 110 mCRPC patients with an age of (69.4±7.5) years (range: 49 to 88 years). Clinical and pathological data, along with metastatic characteristics identified via PSMA PET-CT, were collected and compared. Intergroup comparisons were performed using χ 2 tests. Results:The incidence rates of lymph node metastasis, bone metastasis, and visceral metastasis in the mHSPC group were 71.8% (84/117), 89.7% (105/117), and 11.1% (13/117), respectively, while those in the mCRPC group were 52.7% (58/110), 91.8% (101/110), and 15.5% (17/110), respectively. The incidence of lymph node metastasis in the mHSPC group was significantly higher than that in the mCRPC group ( χ2=8.800, P=0.003). Among patients with bone metastasis, the rates of osteoblastic metastasis, osteolytic metastasis, and mixed metastasis in the mHSPC group were 76.2% (80/105), 8.6% (9/105), and 15.2% (16/105), respectively, while the corresponding rates in the mCRPC group were 74.3% (75/101), 7.3% (8/101), and 16.4% (18/101), respectively, all indicating a relatively high probability of osteolytic and mixed bone metastases ( χ2=0.260, P=0.878). Among patients with mHSPC and mCRPC who tested positive for visceral metastasis, lung metastasis (9/13 and 8/17) and liver metastasis (4/13 and 9/17) were the most common sites of metastasis, but there was no significant difference in the composition of visceral metastasis between the two groups ( χ2=0.933, P=0.564). In this study, among 20 patients who progressed from mHSPC to mCRPC, 35.0% (7/20) had persistent or progressive activity at the original metastatic site, 35.0% (7/20) developed new metastatic lesions, and 30.0% (6/20) showed inhibitory changes in the original metastatic lesions. Among patients with imaging progression, 1/14 of patients with osteoblastic metastatic lesions at the mHSPC stage exhibited osteolytic changes upon progression to mCRPC. Conclusion:Compared with the mCRPC group, the mHSPC group has a higher lymph node metastasis rate,and both groups have common rates of osteolytic and mixed bone metastases and visceral metastasis.
