Objective To investigate the expression and significance of cyclin dependent kinase inhibitor 3(CDKN3)in human papillomavirus type 16(HPV16)-positive cervical cancer.Methods CDKN3 expression in pan-cancer was retrieved and downloaded from the Gene Expression Profiling Interactive Analysis(GEPIA)platform,and the expression levels of CDKN3 between normal cervical tissues(13 samples)and cervical cancer tissues(306 samples)were compared.Subsequently,GSE39001 data of HPV16-positive cervical cancer was sourced and downloaded from the Gene Expression Omnibus(GEO)database,and the expression levels of CDKN3 mRNA in HPV16-positive cervical cancer tissues(43 samples)and normal cervical tissues(12 samples)were compared.Immunohistochemical method was used to detect the expression of CDKN3 in 12 ca-ses of HPV16-positive cervical cancer,12 cases of HPV16-positive cervical precancerous lesions,10 cases of HPV16-positive chronic cervicitis and 7 cases of HPV-negative normal cervical samples collected from the Af-filiated Hospital of Guizhou Medical University.SiHa(HPV16-positive),HeLa(HPV18-positive)and HCC94(HPV-negative)cervical cancer cell lines were selected,and their CDKN3 expression were detected by West-ern blot.Results The GEPIA platform analysis showed that CDKN3 was highly expressed in pan-cancer,and the expression level of CDKN3 in cervical cancer tissue was significantly higher than that in normal cervical tissue(P<0.05).The GEO dataset reflected a significantly increased CDKN3 mRNA expression level in HPV16-positive cervical cancer compared to normal cervical tissue(P<0.001).Immunohistochemical verifi-cation showed that the positive expression rates of CDKN3 in HPV16-positive cervical cancer,HPV16-positive cervical precancerous lesion,HPV16-positive chronic cervicitis and HPV-negative normal cervical tissues were 91.7%,58.3%,0 and 0,respectively.Western blot analysis of cervical cancer cells showed that the expression level of CDKN3 in SiHa(HPV16-positive)cells was significantly higher than that in HeLa(HPV18-positive)and HCC94(HPV-negative)cells(P<0.05).Conclusion CDKN3 is a new oncogene of HPV16-positive cer-vical cancer,which may be used as a marker of cervical precancerous lesions and cervical cancer screening,and may provide a theoretical basis for subsequent mechanism research and targeted therapy.

Objective:To investigate whether Lycopi Herba can serve as a viable alternative to Alismatis Rhizoma in the treatment of heart failure (HF) through network pharmacology and molecular docking techniques.Methods:TCMSP database was used to filter active components of Lycopi Herba and Alismatis Rhizoma. SwissTargetPrediction database was used to predict potential targets. HF-related targets were collected from databases such as GeneCards, OMIM, and DisGeNET. Venny 2.1.0 was used to draw a Venn diagram illustrating the intersection of targets between Lycopi Herba and Alismatis Rhizoma and HF. A protein-protein interaction (PPI) network was established using the String database, and key targets for the treatment of HF with Lycopi Herba and Alismatis Rhizoma were selected using Cytoscape 3.9.1 software to construct a component-intersection target network. The intersection targets were then analyzed for Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways using Metascape. Molecular docking techniques were used to evaluate the affinity between active components and key targets.Results:Lycopi Herba primarily targeted pivotal proteins such as HMGCR and CYP27B1, while Alismatis Rhizoma had a broader target spectrum, including PPARA, JAK2, among others. Shared key targets between the two included HMGCR and ESR1, which were primarily involved in cholesterol synthesis and steroid hormone biosynthesis. Enrichment pathway analysis showed similarities in steroid metabolism between the two; Alismatis Rhizoma, however, was more likely to act through protein phosphorylation regulation and modulating the PI3K-Akt signaling pathway for HF treatment. A unique target for Lycopi Herba in treating HF was CHRM4, indicating its potential for blood pressure regulation and myocardial protection.Conclusions:Both Lycopi Herba and Alismatis Rhizoma exhibit certain commonalities in the treatment of HF, but Alismatis Rhizoma has a wider range of targets and signaling pathways, implying more extensive therapeutic potential. However, considering the nephrotoxicity of Alismatis Rhizoma, Lycopi Herba could be considered as an alternative treatment for HF, especially in patients with renal insufficiency or in the early stages of HF.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Objective:To explore the predictors of upper tract urothelial carcinoma (UTUC) invading muscle.Methods:The preoperative clinical data of 169 patients with UTUC who underwent radical nephroureterectomy (RNU) in the Department of Urology, Second Hospital of Tianjin Medical University from August 2019 to September 2021 were retrospectively collected. The average age of the patients was (67.7±8.3)years. There were 95 male cases (56.2%).15 cases (15.8%) were with diabetes, 46 cases (48.4%) with hypertension, 68 cases (71.6%) with hematuria, 44 cases (46.3%) with renal pelvis tumor, 74 cases (77.9%) with hydronephrosis and 8 cases (8.4%) with multifocality. There were 15 (20.3%), with diabetes, 40(54.1%) with hypertension, 58(78.4%)with hematuria, 32(43.2%) with renal pelvis tumor, 60(81.1%) with hydronephrosis and 2(2.7%) with multifocality among 74 female patients(43.8%), respectively. Patients’ body mass index (BMI) was (24.2±3.2) kg/m 2.The tumor diameter was (3.4±1.8) cm. The average count of neutrophil (NEU) was (4.2±1.7) ×10 9/L, with monocyte (MON) (0.4±0.2) ×10 9/L, platelet (PLT) (237.8±75.3) ×10 9/L and lymphocyte (LYM) (1.7±0.5) ×10 9/L. Neutrophil-to-lymphocyte ratio (NLR) was 2.7±1.4. Mmonocyte-to-lymphocyte ratio (MLR) was 0.3±0.1 and platelet-to-lymphocyte ratio (PLR) was 151.1±59.6. The concentrations of hemoglobin (Hb) and fibrinogen (FIB) were (127.1±18.3) g/L and(3.5±1.0) g/L. Univariate logistic regression analysis was performed on all preoperative data, and a nomogram was established to predict UTUC invading muscle by stepwise regression combined with multivariate logistic analysis. Concordance index (C-index) was used to evaluate the accuracy of the model, and Hosmer-Lemeshow test was used to check the fit. Using 1000 bootstrap resampling to validate the model and draw calibration plot. Receiver operating characteristics (ROC) curves were used to determine the most appropriate cut-off point of the model to predict tumor invasion and evaluate its sensitivity and specificity. Results:In this study, there were 169 cases. Postoperative pathological results showed that 18 cases (10.6%) were of low grade and 151 cases (89.4%) were of high grade. There were 2 patients (1.2%) with pT a stage, 44 patients (26.0%) with pT 1 stage, 37 patients (21.9%) with pT 2 stage, 81 patients (47.9%) with pT 3 stage and 5 patients (3.0%) with pT 4 stage. According to tumor stage, 46 patients were included into non-muscle invasive disease (NMID, pT a/T is/T 1) group and 123 patients were included into muscle invasive disease (MID, pT 2/T 3/T 4) group. Univariate analysis showed that hydronephrosis ( OR=2.919, 95% CI 1.332-6.387, P=0.007) was significantly correlated with MID. Tumor location in ureter ( OR=1.898, 95% CI 0.960-3.800, P=0.067), higher NLR value ( OR=1.313, 95% CI 0.9901.832, P=0.082) and FIB concentration ( OR=1.436, 95% CI 1.008-2.125, P=0.056) might have potential association with MID. Stepwise regression method was used to screen out PLT, FIB and hydronefrosis as the optimal combination for MID prediction. multivariate analysis suggested that PLT decreasing ( OR=0.727, 95% CI 0.548-0.955, P=0.023), FIB increasing ( OR=1.629, 95% CI 1.084-2.552, P=0.025) and hydronephrosis ( OR=2.500, 95% CI 1.111-5.601, P=0.026) were independent predictors of MID.The C-index of the model constructed by the three factors was 0.682, and the P-value of the goodness of fit was 0.778. The ROC curve showed that the optimal cut-off point for the prediction of high-risk MID by the nomogram was 0.627, achieving 39.1% specificity, 88.6% sensitivity and 0.682 area under the curve (AUC). Conclusions:Preoperative decrease of PLT, increase of FIB and hydronephrosis were independent factors for predicting UTUC invading muscle.

Acute mesenteric ischemic disease(AMI) is a critical surgical emergency. Due to its insidious and atypical initial symptoms, a delayed diagnosis significantly increases the mortality rate of AMI patients. The diagnosis and treatment process of AMI often involve close collaboration and communication among multiple disciplines and departments.Our team deeply recognizes the importance of a multidisciplinary team(MDT) model in the standardized management of the AMI disease. It can significantly improve the efficiency of disease diagnosis, delay disease progression, provide timely treatment, and improve the prognosis of patients, thereby reducing the overall mortality rate. Therefore, combining our center′s experience in treating AMI patients with the implementation of the MDT model, we elaborated on the key steps and quality control measures for the standardized application of the MDT model in AMI disease, with the aim of providing a theoretical foundation and experiential reference for colleagues and professionals.

Improving the reproducibility of biomedical research results remains a major challenge. Transparent and accurate reporting of progress can help readers evaluate the reliability of research results and further explore an experiment by repeating or building upon its findings. The ARRIVE 2.0 guidelines, released in 2019 by the UK National Centre for the Replacement, Refinement, and Reduction of Animals in Research (NC3Rs), provide a checklist applicable to any in vivo animal research report. These guidelines aim to improve the standardization of experimental design, implementation, and reporting, as well as the reliability, repeatability, and clinical translatability of animal experimental results. The use of the ARRIVE 2.0 guidelines not only enriches the details of animal experimental research reports, ensuring that information on animal experimental results is fully evaluated and utilized, but also enables readers to understand the content expressed by the author accurately and clearly, promoting the transparency and integrity of the fundamental research review process. At present, the ARRIVE 2.0 guidelines have been widely adopted by international biomedical journals. This article is the second part of the Chinese translation of the complete interpretation of the ARRIVE 2.0 guidelines published in PLoS Biology in 2020 (original text can be found at https://arriveguidelines.org) and based on the best practices for following the ARRIVE 2.0 guidelines in international journals. This part includes Items 4-7 of "ARRIVE Essential 10" in the ARRIVE 2.0 guidelines: "Randomization", "Blinding", "Outcome Measurement", and "Statistical Methods". Our Chinese translated version aims to promote the full understanding and use of the ARRIVE 2.0 guidelines by domestic researchers, enhancing the standardization of experimental animal research and reporting, and promoting the high-quality development of experimental animal technology and comparative medicine research in China.

Objective:To investigate ultrasonographic manifestations of gonococcal infections of the penile skin and accessory glands in men, and to assess their clinical significance.Methods:From January 2014 to January 2021, male patients with gonococcal infections of the penile skin and accessory glands were collected from Department of Dermatology, Changshu No.1 People′s Hospital. The diagnosis had been confirmed by laboratory examinations, and these patients had not received relevant treatment. The real-time ultrasound imaging system SIEMENS ACUSON X300 was used to examine the penile skin and accessory gland lesions infected with Neisseria gonorrhoeae, with the probe frequency ranging from 7.5 to 15 MHz. Patients with tubular anechoic fluid-filled areas on the high-frequency ultrasound images received a single dose of intramuscular ceftriaxone (1 g) ; those with oval-shaped anechoic fluid-filled areas on the high-frequency ultrasound images received incision and drainage followed by intramuscular injection of ceftriaxone at a dose of 1 g once a day for 5 consecutive days; those with hypoechoic or mixed echoic areas on the high-frequency ultrasound images received intramuscular injection of ceftriaxone at a dose of 1 g once a day for 5 consecutive days, and if the nodules did not regress after 1-month treatment, local resection would be performed. One month after the treatment, the patients were followed up, and the efficacy was evaluated. Results:A total of 32 male patients with gonococcal infections of the penile skin and accessory glands were collected. They were aged 28.54 ± 3.27 years, all had a history of non-marital sexual contact, and the duration from non-marital sexual contact to the onset of symptoms was 4.45 ± 1.03 days. The disease course was 8.64 ± 1.87 days. Lesions were all solitary, and located at the external urethral meatus in 16 cases (50.00%) , at the glans penis in 7 cases (21.88%) , beside the foreskin frenulum in 5 cases (15.62%) , and at the penile raphe in 4 cases (12.50%) . Sixteen patients (50.00%) presented with sinus-like lesions, 9 (28.13%) with abscesses, 7 (21.87%) with nodules, and all had tenderness on palpation. High-frequency ultrasound examination showed tubular anechoic fluid-filled areas in 16 cases (50.00%) , oval-shaped anechoic fluid-filled areas in 7 cases (21.88%) , hypoechoic areas in 5 cases (15.62%) , and mixed echoic areas in 4 cases (12.50%) . Gonococcal infections involved the cavernous body of the urethra in 16 cases (50.00%) , cavernous body of the penis in 5 cases (15.62%) , and subcutaneous tissue of the penis in 11 cases (34.38%) . After the treatment, all the patients were cured.Conclusion:High-frequency ultrasound can be used in the assessment of skin lesions and selection of treatment regimens for male patients with gonococcal infections of the penile skin and accessory glands.

Objective:To investigate the value of plasma Epstein-Barr virus (EBV) DNA detection in the screening of nasopharyngeal carcinoma (NPC) and its clinical application in non-high-risk areas.Methods:Plasma EBV DNA results in 1 153 newly diagnosed nasopharyngeal carcinoma patients who were treated in Sichuan Cancer Hospital from 2015 to 2020 and 244 healthy control cases with matched sex and age were retrospectively analyzed. EBV DNA were detected by quantitative real-time PCR. Positive rate of EBV DNA was determined by the cutoff value of 400 (≥400 copies/ml as positive) and optimization threshold method (presence of S amplification curve as positive). Further analyses were conducted to compare EBV DNA load in different clinical stage, TNM stage and regions distribution characteristics. Receiver operating characteristic (ROC) curve analysis was performed to evaluate the diagnostic value of the cutoff value of 400 and optimization threshold method for NPC.Results:Compared with healthy controls, EBV DNA increased significantly in newly diagnosed NPC patients ( P<0.001). Both evaluation methods revealed that the EBV DNA positive percentage increased with TNM and clinical stage ( P<0.001). With 400 copies/ml as cutoff value, the diagnostic sensitivity and specificity were 40.85% and 100%, respectively. The area under the curve was 0.704 (95% CI 0.676-0.733, P<0.001). Evaluated by the optimization threshold method, the sensitivity and specificity could improve to 82.0% and 99.2%, respectively, and the area under the curve reached 0.910 (95% CI 0.894-0.924, P<0.001). Conclusions:In the low prevalence area of nasopharyngeal carcinoma, the sensitivity for diagnosis of nasopharyngeal carcinoma is only 40.9% by the 400 copies/ml cutoff value method. The optimization threshold method is a better choice to improve the diagnostic sensitivity without lowering the diagnostic specificity.
