ObjectiveTo investigate the possible mechanism of Pibai Yucuo Formula （枇柏愈痤方， PYF） in treating acne from the perspective of skin barrier damage. MethodsThirty-two mice were randomly divided into blank group， model group， minocycline group， and PYF group， with 8 mice in each group. Except for the blank group， mice were induced by intradermal injection of Cutibacterium acnes （C.acnes） combined with topical application of artificial sebum to establish acne model. The blank group and model group received intragastric administration of 0.2 ml of distilled water， while the PYF group received intragastric administration of 22.75 g/（kg·d）of PYF， and the minocycline group received 0.013 g/（kg·d）of minocycline suspension， all once daily for 5 consecutive days. On day 0 and day 6 of the experiment， the body weight of mice in each group was recorded， and the absolute value of the body weight difference during the experiment was calculated. Skin conditions were assessed with multifunctional skin imaging system on the 2nd， 4th and 6th day of the experiment. Skin barrier function indicators including transepidermal water loss （TEWL）， and the water content of the stratum corneum and epidermis on day 0， 2， 4 and 6 of the experiment. Optical coherence tomography （OCT） was used to observe stratum corneum and skin thickness on the 1st， 3rd and 5th day of the experiment. Hematoxylin-eosin （HE） staining was performed to observe histopathological changes， while ELISA was used to detect interleukin-17A （IL-17A） levels， and immunofluorescence staining was used to assess skin barrier-related proteins filaggrin （FLG） and loricrin （LOR） levels of skin lesions on day 6 of the experiment. ResultsCompared to the blank group， the model group showed a decrease in body weight on day 6， and an increase in the absolute value of the difference in body weight before and after the experiment （P＜0.05）. On day 4 and 6， TEWL values increased， while water content in the skin stratum corneum and epidermis decreased （P＜0.05）， accompanied by elevated IL-17A level and reduced immunofluorescence intensity of FLG and LOR proteins （P＜0.05）. The model group mice showed papules or pustules at the skin modeling site with progressively worsening desquamation under multifunctional skin imaging system. OCT revealed focal epidermal protrusions， blurred epidermal-dermal boundaries， and disorganized structural layers. HE staining showed significant epidermal hyperkeratosis and incomplete keratinization in the skin， with keratin plug formation in hair follicles and glandular lumens， thickened stratum corneum， hyperplasia of the stratum spinosum， as well as dense dermal inflammatory cell infiltration， and capillary dilation. Compared to the model group， both the minocycline group and the PYF group showed a reduced difference in body weight before and after experiment （P＜0.05）. On day 4 and 6， the TEWL value decreased， and water content of the skin stratum corneum increased （P＜0.05）； on day 6， the IL-17A level in the skin lesions decreased and immunofluorescence intensity of FLG and LOR proteins increased （P＜0.05）. On day 4 and 6， the severity of the skin lesions and range of redness and swelling were lighter than those in the model group， with reverted epidermal thickness， smoother surface and clearer epidermis-dermis boundary. HE staining showed that the degree of skin keratinization was reduced， and the inflammatory infiltration and vascular dilation in the dermis were improved compared to the model group. The PYF group showed better results than the minocycline group in reducing TEWL value on day 4 （P＜0.05）. ConclusionPYF may improve inflammation and skin barrier damage by downregulating IL-17A levels in lesion tissue and increasing skin barrier-related proteins， which could be one of the potential mechanism of action on acne.

Objective To investigate the levels and influencing factors for eye lens dose of interventional radiology workers, and to provide a basis for reasonable and scientific radiation protection. Methods Thermoluminescent eye lens dosimeters were used to monitor the left and right eye lens doses of interventional radiology workers in real time during different surgical positions and varying eye protection conditions. The annual eye lens doses for the operators were estimated based on their yearly workload. The differences in eye lens doses under different conditions were analyzed and the influencing factors were identified. Results For individual interventional operations, the range of personal dose equivalent H_p(3) of the left eye of interventional radiology workers was ( < MDL ~ 418.33) μSv, the median (Q₁, Q₃) was 9.29 ( < MDL, 40.79) μSv, and the mean was 40.79 ± 70.36 μSv. The estimated annual eye lens doses were 4.05 mSv and 17.80 mSv based on the median and mean values of the eye lens dose of a single operation multiplied by average annual frequency of operations per person, respectively. The left eye lens dose was higher than the right eye lens dose of the same operator (Z = −4.24, P < 0.05), and the dose of the right eye lens was strongly positively correlated with that of the left eye lens. The left eye lens dose of the first surgeon was higher than that of the second surgeon in the same operation (Z = −3.10, P < 0.05). The eye lens dose was influenced by operator position (χ² = 9.149, P = 0.002, OR = 8.343), eye protection (χ² = 4.619, P = 0.032, OR = 4.352), and air kerma area product (χ² = 8.032, P = 0.005, OR = 5.488). Conclusion According to the results of this study, a significant portion of interventional operators have eye lens doses that approach or exceed international occupational dose limits. It is recommended to pay attention to the operation frequency of the first operator and the air kerma area product of interventional operation, and strengthen radiation protection and dose monitoring for the eye lens of interventional radiology workers.

Objective:To explore the effects of holmium laser enucleation of the prostate with early complete transection of the urethral mucosa at the tip of the prostate on urinary control function and sexual function in patients with benign prostatic hyperplasia (BPH).Methods:Eighty patients with BPH who underwent holmium laser enucleation of the prostate in the Affiliated Hospital of Yan′an University from January 2019 to January 2023 were collected as the research subjects. The patients were divided into the observation group and the control group by the random number table method, with 40 cases in each group. The observation group underwent early holmium laser enucleation of the prostate with early complete transection of the urethral mucosa at the tip of the prostate, while the control group underwent conventional holmium laser prostatectomy. The general conditions, urinary control function and sexual function of the two groups of patients after the operation were compared. The adverse ejaculation conditions 6 months after the operation were recorded.Results:There was no statistically significant difference in age and prostate volume between the two groups of patients (all P>0.05). The operation time, intraoperative blood loss, postoperative indwelling urinary catheter time and postoperative hospital stay in the observation group were significantly less than those in the control group (all P<0.05). The International Prostate Symptom Scale (IPSS) score, Quality of Life (QOL) score, the maximum flow rate (Qmax), and post void residual (PVR) in the bladder of the two groups of patients 6 months after the operation were compared with those before the operation, and the differences were statistically significant (all P<0.05), while there were no statistically significant differences between the groups (all P>0.05). There were no statistically significant differences in the International Index of Erectile Function (IIEF-5) scores and Erection Hardness Grading Scale (EHGS) grades of the two groups of patients 6 months after surgery compared with those before surgery (all P>0.05), and there were also no statistically significant differences between the groups (all P>0.05). There was no statistically significant difference in the ejaculation function score and ejaculation distress score 6 months after the operation in the observation group compared with those before the operation (all P>0.05), while in the control group, the ejaculation function score 6 months after the operation was lower than that before the operation, and the ejaculation distress score was higher than that before the operation (all P<0.05). The ejaculation function score and ejaculation distress score of the observation group 6 months after the operation were significantly better than those of the control group (all P<0.05). The incidences of retrograde ejaculation and reduced semen volume 6 months after the operation in the observation group were both lower than those in the control group (all P<0.05). There was no statistically significant difference in the incidence of rapid ejaculation, ejaculation pain, hematospermia, etc. between the two groups of patients 6 months after the operation (all P>0.05). Conclusions:In holmium laser enucleation of the prostate, early complete transection of the urethral mucosa at the tip of the prostate has an improving effect on urinary control function and sexual function in patients with BPH, and increases the confidence in postoperative life and satisfaction with orgasm of BPH patients.

Objective To investigate the effect and mechanism of Taxilli Herba decoction in preventing miscarriage in rats with threatened abortion.Methods Seventy-two SPF-grade SD rats were co-housed at a male-to-female ratio of 2∶1.Forty-eight pregnant rats were subsequently divided into a normal group,a threatened abortion model group,a positive control group,as well as Taxilli Herba decoction low/medium/high dose groups(n=8 rats per group).Rats in the positive control group received 3.02 mg/kg dydrogesterone intragastrically,and rats in the low-,medium-,and high-dose Taxilli Herba decoction groups received 2.5,5,and 10 g/kg Taxilli Herba decoction intragastrically,respectively.The normal and model groups received intragastric distilled water once a day for 10 consecutive days.On day 10 after administration of the corresponding treatment,rats in all groups except the normal group received intragastric administration of 3.75 mg/kg mifepristone suspension.The effects of Taxilli Herba on the vaginal bleeding rate and abortion rate were observed.Serum levels of follicle-stimulating hormone(FSH),luteinizing hormone(LH),estrogen(E),progesterone(P),vascular endothelial growth factor(VEGF),testosterone(T),and aromatase and E and P levels in the ovary in pregnant rats were detected by enzyme-linked immunosorbent assay.Expression levels of E receptor(ER),P receptor(PR),VEGF receptor 2(VEGFR2),and platelet endothelial cell adhesion molecule-1(CD31)in the uterine decidua in pregnant rats were detected by immunofluorescence staining,and semi-quantitative analysis was performed.Results Mifepristone significantly increased the vaginal bleeding rate and abortion rate in pregnant rats,but these were effectively reduced by treatment with Taxilli Herba water decoction.Taxilli Herba water decoction also increased serum E,P,and VEGF,and ovary levels of E and P(P＜0.05).The treatment also decreased serum LH,maintained the secretion of FSH,and enhanced ER,PR,VEGFR2,and CD31 expression in decidual tissue.Conclusions Taxilli Herba demonstrated effective miscarriage-prevention effects in a rat model of threatened abortion.Its mechanism of action involves regulating the normal physiological function of the hypothalamic-pituitary-gonadal axis upstream of the uterus,and enhancing the expression of the downstream P/PR/VEGF/VEGFR2 and E/ER/VEGF/VEGFR2 pathways.

Objective:To analyze the efficacy and prognostic factors of fractionated stereotactic radiotherapy (FSRT) for patients with breast cancer brain metastases (BCBM).Methods:Medical records and follow-up data of BCBM patients who underwent FSRT in Cancer Hospital Chinese Academy of Medical Sciences, Shenzhen Center and Shenzhen People's Hospital from August 2019 to May 2023 were collected. The R Studio platform of the R version 4.2.1 statistical software was applied to analyze patients' baseline characteristics, 1- and 2-year local brain control (LBC), overall survival (OS) and distant brain control (DBC) and corresponding median failure-free survival, draw survival curve using Kaplan-Meier method. Prognostic factors were screened by univariate analysis and multivariate analysis (Cox regression).Results:Cumulatively, 52 patients (163 metastases in total) had a median survival follow-up of 22.1 months, 83% were<60 years old. Molecular typing: 13 cases (25%) were positive for human epidermal growth factor receptor 2 (HER2+) / hormone receptor negative (HR-), 2 cases (4%) were luminal A, 26 cases (50%) were luminal B, and 11 cases (21%) were triple negative. The median number of brain metastases was 2 (range: 1 - 17). Follow-up outcomes: the median OS was 34.0 months, with 1- and 2-year OS rates of 85.6% and 65.4%, respectively; the median LBC was 20.6 months, with 1- and 2-year LBC rates of 79.2% and 45.2%, respectively; and the median DBC was 10.3 months, with 1- and 2-year DBC rates of 46.7% and 28.9%, respectively. During follow-up, 13 patients underwent salvage local therapy (10 FSRT); 5 developed radiation necrosis (1 symptomatic). Prognostic factor analysis: absence of extracranial organ metastases (compared with ≥3) was a protective factor for OS, P<0.05. For LBC, fewer (1 - 2) extracranial organ metastases (compared with ≥3), and single brain metastasis (compared with ≥2) were favorable prognostic factors , while N 3 staging upon initial diagnosis was a poor prognostic factor (all P<0.05). For DBC, brain metastasis after surgery was a good prognostic factor, while complicated with lung metastasis and asymptomatic brain metastasis at the first diagnosis were poor prognostic factors (all P<0.05). Conclusions:FSRT yields relatively good LBC and poor DBC for BCBM patients. A certain percentage of patients require salvage FSRT during follow-up, but OS is maintained acceptable and the radiation necrosis is tolerable. Among the prognostic factors, the absence of extracranial metastatic organs is a good prognostic factor for OS; patients with single brain metastasis, fewer extracranial metastatic organs, and non-N 3 staging upon initial diagnosis can obtain better LBC after FSRT.

Objective:To investigate the hospitalization utilization of pneumoconiosis patients and its influencing factors in a northwestern city, and to provide theoretical basis for formulating service policies for pneumoconiosis patients.Methods:From March to October 2021. Existing living pneumoconiosis patients in kashgar were selected as the research objects. The "Survey Questionnaire on Medical Behaviors and Influencing Factors of Pneumoconiosis Patients" developed by the National Institute of Occupational Health and Poison Control of China Centers for Disease Control and Prevention was used to collect pneumoconiosis patients infomations from March to October 2021. This study investigated the demographic characteristics of pneumoconiosis patients, the types and stages of pneumoconiosis, as well as hospitalization in the past year, reasons for hospitalization, treatment measures, reasons for discharge. Additionally, it examined factors influencing medical behaviors, including medical insurance reimbursement, work-related injury insurance, and compensation situations.Logistics regression was used to analyze the influencing factors of hospitalization utilization.Results:The average age of the pneumoconiosis patients was elder with the age of 64.8. 86.7% (156/178) of them were retired, 75.8% (135/178) of them relied primarily on pensions for their income. The main types of pneumoconiosis were silicosis and coal workers' pneumoconiosis with the proportion of 57.3% (102/178) and 24.2% (43/178). 67.4% of them were stage I. The hospitalization rate in the year prior to the survey was 37.1%. The factors that promoted hospitalization were pension as the main source of income, pneumoconiosis in stage II, silicosis as the pneumoconiosis type, suffering joint pain, with two OR more other lung diseases (tuberculosis, cor pulmonale, COPD, pulmonary infection, bulla or pneumothorax, lung cancer, or mesothelioma) ( P<0.05) . Conclusion:The hospitalization rate of pneumoconiosis patients in the previous year was low. It is mainly influenced by the patient's economic income, the duration of pneumoconiosis, and the presence of comorbidities.

Ovarian cancer poses a significant threat to women's health, necessitating effective therapeutic strategies. Emd-D, an emodin derivative, demonstrates enhanced pharmaceutical properties and bioavailability. In this study, Cell Counting Kit 8 (CCK8) assays and Ki-67 staining revealed dose-dependent inhibition of cell proliferation by Emd-D. Migration and invasion experiments confirmed its inhibitory effects on OVHM cells, while flow cytometry analysis demonstrated Emd-D-induced apoptosis. Mechanistic investigations elucidated that Emd-D functions as an inhibitor by directly binding to the glycolysis-related enzyme PFKFB4. This was corroborated by alterations in intracellular lactate and pyruvate levels, as well as glucose transporter 1 (GLUT1) and hexokinase 2 (HK2) expression. PFKFB4 overexpression experiments further supported the dependence of Emd-D on PFKFB4-mediated glycolysis and SRC3/mTORC1 pathway-associated apoptosis. In vivo experiments exhibited reduced xenograft tumor sizes upon Emd-D treatment, accompanied by suppressed glycolysis and increased expression of Bax/Bcl-2 apoptotic proteins within the tumors. In conclusion, our findings demonstrate Emd-D's potential as an anti-ovarian cancer agent through inhibition of the PFKFB4-dependent glycolysis pathway and induction of apoptosis. These results provide a foundation for further exploration of Emd-D as a promising drug candidate for ovarian cancer treatment.

Objective:To investigate the diagnostic value of fetal cardiac ultrasound view visualization in the first trimester for congenital heart disease（CHD）.Methods:A retrospective analysis was performed on 13 323 singleton fetuses who underwent first-trimester（11-13 +6 weeks）ultrasound screening at the Ultrasound Medicine Center，the Affiliated Suzhou Hospital of Nanjing Medical University from January 2018 to June 2024. Cardiac views including the four-chamber view（4CV），left ventricular outflow tract view（LVOT），and Results:The study group showed significantly higher rates of "poorly visualized" 4CV，LVOT，and 3VT than the control group（2.70% vs. 0.14%， P=0.005；36.49% vs. 4.76%， P<0.001；36.49% vs.2.46%， P<0.001）. The efficacies of combination 1（any view abnormal）and combination 2（any view "poorly visualized" or "abnormal"）were comparable，with AUCs of 0.86 and 0.85（ P=0.424）. The AUCs of combination 3（3VT "poorly visualized" or any view "abnormal"）and combination 4（4CV "poorly visualized" or any view "abnormal"）were 0.88 and 0.86（ P=0.424），all significantly higher than combination 5（LVOT "poorly visualized" or any view "abnormal"，AUC=0.84，all P<0.05）. Conclusions:"Poorly visualized" cardiac views in the first trimester demonstrate good diagnostic efficacy for CHD，particularly when 3VT or 4CV are affected，warranting heightened clinical vigilance for fetal cardiac anomalies.

Obesity is a significant risk factor for cancer and is associated with breast cancer metastasis. Nevertheless, the mechanism by which alterations in systemic metabolism affect tumor microenvironment (TME) and consequently influence tumor metastasis remains inadequately understood. Herein, we found that perturbations in circulating metabolites induced by obesity promote metastasis-like phenotypes in breast cancer. Oleoylcarnitine (OLCarn) concentrations were elevated in the serum of obese mice and humans. Administration of exogenous OLCarn induces metastasis-like characteristics in breast cancer cells. Mechanistically, OLCarn directly interacts with the Arg176 site of adenylate cyclase 10 (ADCY10), leading to the activation of ADCY10 and enhancement of cAMP production. Mutations at Arg176 prevent OLCarn from binding to ADCY10, disrupting the ADCY10-mediated activation of cyclic adenosine monophosphate (cAMP) signaling pathway. This activation promotes transcription factor 4 (TCF4)-dependent kinesin family member C1 (KIFC1) transcription, thereby driving breast cancer metastasis. Conversely, the neutralization of both ADCY10 and KIFC1 through knockdown or pharmacological inhibition abrogates the oncogenic effects mediated by OLCarn. Hence, obesity-induced systemic environmental changes lead to the aberrant accumulation of OLCarn within the TME, making it a potential therapeutic target and biomarker for breast cancer.
