BACKGROUND:Primary osteoporosis has a high incidence,but the pathogenesis is not fully understood.Currently,there is a lack of effective early screening indicators and treatment programs. OBJECTIVE:To further explore the mechanism of primary osteoporosis through comprehensive bioinformatics analysis. METHODS:The primary osteoporosis data were obtained from the gene expression omnibus(GEO)database,and the differentially expressed genes were screened for Gene Ontology(GO)function and Kyoto Encyclopedia of Genes and Genomes(KEGG)pathway enrichment analysis.In addition,the differentially expressed genes were subjected to protein-protein interaction network to determine the core genes related to primary osteoporosis,and the least absolute shrinkage and selection operator algorithm was used to identify and verify the primary osteoporosis-related biomarkers.Immune cell correlation analysis,gene enrichment analysis and drug target network analysis were performed.Finally,the biomarkers were validated using qPCR assay. RESULTS AND CONCLUSION:A total of 126 differentially expressed genes and 5 biomarkers including prostaglandins,epidermal growth factor receptor,mitogen-activated protein kinase 3,transforming growth factor B1,and retinoblastoma gene 1 were obtained in this study.GO analysis showed that differentially expressed genes were mainly concentrated in the cellular response to oxidative stress and the regulation of autophagy.KEGG analysis showed that autophagy and senescence pathways were mainly involved.Immunoassay of biomarkers showed that prostaglandins,retinoblastoma gene 1,and mitogen-activated protein kinase 3 were closely related to immune cells.Gene enrichment analysis showed that biomarkers were associated with immune-related pathways.Drug target network analysis showed that the five biomarkers were associated with primary osteoporosis drugs.The results of qPCR showed that the expression of prostaglandins,epidermal growth factor receptor,mitogen-activated protein kinase 3,and transforming growth factor B1 in the primary osteoporosis sample was significantly increased compared with the control sample(P<0.001),while the expression of retinoblastoma gene 1 in the primary osteoporosis sample was significantly decreased compared with the control sample(P<0.001).Overall,the study screened and validated five potential biomarkers of primary osteoporosis,providing a reference basis for further in-depth investigation of the pathogenesis,early screening and diagnosis,and targeted treatment of primary osteoporosis.

Objective:To explore the application effect of high-fidelity intelligent simulator combined with scenario simulation for emergency response training in the Department of Radiology, and to improve the emergency preparedness of medical, nursing, and technical staff in managing contrast agent adverse reactions.Methods:From January to July 2024, 132 medical, nursing, and technical staff from the Department of Radiology of a tertiary hospital in Chengdu City, China were selected as the training subjects. The high-fidelity intelligent simulator combined with scenario simulation teaching mode was used to conduct emergency response training for the participants. The differences in theoretical knowledge and post competence regarding contrast agent adverse reactions among the staff were compared before and after the training. A self-made questionnaire was used to investigate their needs and satisfaction of the emergency response training. SPSS 26.0 was used for data analysis. The differences in theoretical knowledge and post competence scores before and after training were compared using the paired samples t test. Results:After the training, the average score of theoretical knowledge examination increased from (84.32±10.19) points to (90.34±7.87) points, and the difference was statistically significant ( P<0.001). After the training, the scores of knowledge reserve, operational skills, situational decision-making ability, professional literacy, comprehensive literacy, and overall post competency were all significantly higher than those before the training ( P<0.05). The satisfaction score of emergency response training was (4.17±0.25) points. Conclusions:High-fidelity intelligent simulator combined with scenario simulation training improved the emergency preparedness and teamwork of radiology staff in clinical emergencies. The training received high recognition and satisfaction from the participants, which is of great significance for clinical emergency response and patient safety.

Objective Based on the sampling test of national drugs,the quality of Huatan Pingchuan tablets was systematically evaluated,and the quality problems were analyzed to provide references and suggestions for the quality control of this variety and to improve its quality standard.Methods A total of 157 batches of samples were tested according to the statutory standard,and based on the testing results and prescription characteristics,microscopic identification and comprehensive analysis of its quality using thin-layer chromatography,high-performance liquid chromatography,and other methods were subsequently established or improved for the exploratory research.Results The established thin-layer chromatography identification for Radix Scutellariae,as well as the content determination methods for Radix Scutellariae,Syringae Cortex,and promethazine hydrochloride,are easy to operate and have good durability and specificity and can be applied to the quality control and evaluation of Huatan Pingchuan tablets.Conclusions The overall quality of the tablets is average;some enterprises should strengthen the quality control of raw medicinal materials(decoction pieces);individual enterprises have significant differences in the quality of samples from different batches,so they need to pay attention to the quality of raw materials and the stability of production processes;the inspection items of the current standards cannot fully reflect the key quality attributes of drugs,and standards improvement work needs to be carried out.

Objective:To compare the efficacy of surgical resection and radiofrequency ablation (RFA) treatment for China liver cancer staging (CNLC) Ia hepatocellular carcinoma (HCC) at difficult-to-reach locations.Methods:A retrospective analysis was conducted on the clinical data of 114 patients with CNLC Ia HCC at Ⅶ、Ⅷ、Ⅳb or Ⅰ segments that were difficult-to-reach locations who were admitted to People's Hospital of Zhengzhou University from December 2018 to December 2023. Among the patients, 85 were males and 29 were females, aged (58.1±1.0) years. The patients were divided into two groups: a RFA group with 31 cases and a surgical resection group with 83 cases. Compare the levels of alanine transaminase (ALT) and aspartate transaminase (AST) before and after surgery, the surgical time, intraoperative blood loss, postoperative hospital stay, postoperative complications, recurrence free survival rate, and cumulative survival rate between the two groups.Results:The comparison of age, gender, ALT, and AST between the two groups showed no statistically significant differences (all P>0.05). The differences in ALT and AST levels before and after surgery in the RFA group were (134.8±38.7) U/L and (195.1±53.9) U/L, respectively, which were significantly lower than those in the surgical resection group [(226.8±17.9) U/L and (229.5±16.2) U/L] ( t=-2.45 and -1.12, P=0.016 and 0.041). The RFA group had shorter operation time [(69.2±11.7) min vs. (210.6±8.9) min], less intraoperative blood loss [(8.7±3.8) ml vs. (238.6±20.8) ml], and shorter postoperative hospital stays [(6.4±1.0) d vs. (13.1±0.4) d] compared to the surgical resection group, with all differences statistically significant (all P<0.05). The overall complication rates were 19.4% (6/31) in the RFA group and 22.9% (19/83) in the surgical resection group, showing no significant difference ( χ2=0.16, P=0.685). No statistically significant diffe-rence was found in recurrence-free survival rates between the two groups ( χ2=0.13, P=0.717). Similarly, there was no statistically significant difference in cumulative survival rates between the groups ( χ2<0.01, P=0.978). Conclusion:For HCC at CNLC Ⅰa in challenging locations, RFA demonstrated shorter operation time and postoperative hospital stay, less intraoperative bleeding, and superior liver function recovery compared with surgical resection, while no significant difference was observed in survival outcomes between the two treatment groups.

Background and purpose:Human papilloma virus(HPV)infection status is crucial for diagnosing cervical precancerous lesions and classifying cervical cancer.High-risk(HR)HPV is often linked to P16 protein overexpression,so P16 detection via immunohistochemistry(IHC)is commonly used to assess HPV infection.However,the differences between HPV status and P16 expression remains unclear.An in-depth study of the correlation between HPV and P16 is essential for clinical guidance.Methods:We retrospectively collected clinical and pathological data of cervical lesions from 618 patients diagnosed at the Department of Pathology,Fudan University Shanghai Cancer Center from January 2020 to December 2023(Ethical number:050432-4-2307E).Polymerase chain reaction(PCR)reverse dot hybridization was used to detect HPV including HR and low-risk(LR)subtypes,and immunohistochemistry was used to detect P16 for comparative analysis.Based on different clinical and pathological diagnoses,the sensitivity and specificity of P16 expression in evaluating HPV infection were evaluated.Among the 618 cases of cervical lesions,there were 92 cases of cervical squamous cell carcinoma,257 cases of cervical adenocarcinoma,79 cases of high-grade squamous intraepithelial lesions(HSIL),105 cases of low-grade squamous intraepithelial lesions(LSIL),and 85 cases of chronic cervical inflammation.Results:According to clinical diagnosis,the HR-HPV positive rate in cervical squamous cell carcinoma was 88.0%(81/92),the P16 positive rate was 91.3%(84/92),and the overall consistency rate between P16 and HPV detection was 90.2%(88/92);for HR-HPV infection,the sensitivity and specificity of P16 were 96.3%and 45.5%.The positive rate of HR-HPV in adenocarcinoma was 54.5%(140/257),the positive rate of P16 was 58.8%(151/257),and the overall consistency rate between P16 and HPV detection was 82.5%(212/257);for HR-HPV infection,the sensitivity and specificity of P16 were 87.9%and 76.1%.In HSIL,the HR-HPV positive rate was 75.9%(60/79),the positive rate of P16 was 70.9%(56/79),and the overall consistency rate between P16 and HR-HPV detection was 82.2%(65/79);for HR-HPV infection,the sensitivity and specificity of P16 were 85.0%and 73.7%.In LSIL,the HR-HPV positive rate was 73.3%(77/105),the positive rate of P16 was 8.5%(9/105),and the overall consistency rate between P16 and HR-HPV detection was 33.3%(35/105);for HR-HPV infection,the sensitivity and specificity of P16 were 10.4%and 96.4%.In chronic cervical inflammation,the HR-HPV positive rate was 20%(17/85),the positive rate of P16 was 0.0%(0/85);for HR-HPV infection,the sensitivity and specificity of P16 were 0.0%and 100.0%.There was a significant positive correlation between P16 positivity and HPV16/18 in cervical squamous cell carcinoma,adenocarcinoma,and HSIL(P=0.000),while there was no significant correlation in LSIL and chronic cervical inflammation(P＞0.05).Conclusion:In cervical squamous cell carcinoma and adenocarcinoma,the consistency of P16 expression and HPV DNA positivity are high,especially in HPV16/18 subtype.There is a good concordance between HR-HPV positivity and P16 protein overexpression.The positive expression of P16 in HSIL may initially reflect HPV infection status.However,in LSIL and chronic cervicitis,P16 expression may not accurately correlate with HPV infection.The inconsistency between P16 and HPV DNA testing could be influenced by multiple factors,including HPV subtypes,histopathological categories,specimen quality,and technical limitations.In clinical practice,it is recommended to conduct comprehensive analysis or employ multiple diagnostic methods to confirm HPV infection status for precise evaluation.

Recent studies have shown that the physiological homeostasis of oral mucosal cells is regulated by the circadian clock.Dis-ruption or dysfunction of the circadian clock is closely associated with the development of oral squamous cell carcinoma(OSCC).Research based on the circadian clock offers a novel perspective on the pathogenesis and therapeutic strategies for OSCC.However,there is current-ly limited research on this topic,and people generally have insufficient understanding and recognition of the circadian clock.Given the complexity and challenges of circadian clock which is the fourth dimension of medical research,we organize relevant experts based on summarizing the current research results of circadian clock in the pathogenesis and precision diagnosis and treatment of OSCC,combining the scientific principles of the circadian clock's role and their long-term research experience,then summarizes and recommends the con-sensus opinions for the research of circadian clock in the pathogenesis mechanism and precision diagnosis and treatment of human OSCC,with the hope of providing guidance for the basic research and clinical application of circadian clock or circadian rhythm in the pathogene-sis mechanism and precision diagnosis and treatment of oral and maxillofacial squamous cell carcinoma.

Purpose To identify hepatocellular carcinoma that responds to repetitive transcatheter arterial chemoembolization(TACE)based on CT radiomics.Materials and Methods A total of 96 patients diagnosed as hepatocellular carcinoma in the First Affiliated Hospital of Xinjiang Medical University from February 2018 to May 2024 were randomly divided into a training group(n=67)and internal validation group(n=29)at a ratio of 7∶3.All patients received three or more TACE treatments.Radiomics features were extracted from lipiodol of the target-lesions by semi-automatic segmentation on the axial CT image after TACE within 24 hours.The radiomics model were constructed by five features for differentiating non-response group from response group.Receiver operating characteristic curve analysis and decision curve were performed to evaluate the performance of the model.Results Child-Pugh classification(OR=2.737,P<0.05),BCLC stage(OR=2.907,P<0.05),multifocal tumors(OR=4.505,P<0.01)and alpha-fetoprotein(OR=1.002,P<0.01)were independent risk factors for predicting tumor response after TACE.The area under the curve of the non-contrast CT based model and the arterial-enhanced CT based model were 0.813 and 0.831 in the experimental group;0.748 and 0.788 in the validation group,respectively.Both of the two models showed good prediction performance.Conclusion The radiomics model based on CT imaging features after first TACE is effectively for differentiating non-response group from response group,lipiodol retention patterns from the target lesion can be the imaging biomarkers for TACE response prediction.
