Objective： The aim of this study is to explore the predictive value of biparametric magnetic resonance imaging(bpMRI)for pelvic lymph node metastasis in prostate cancer patients with PSA≤20 μg/L and establish a nomogram. Methods： The imaging data and clinical data of 363 patients undergoing radical prostatectomy and pelvic lymph node dissection in the First Affiliated Hospital of Nanjing Medical University from July 2018 to December 2023 were retrospectively analyzed. Univariate analysis and multivariate logistic regression were used to screen independent risk factors for pelvic lymph node metastasis in prostate cancer, and a nomogram of the clinical prediction model was established. Calibration curves were drawn to evaluate the accuracy of the model. Results： Multivariate logistic regression analysis showed extrocapusular extension (OR=8.08,95%CI=2.62－24.97, P<0.01), enlargement of pelvic lymph nodes (OR=4.45,95%CI=1.16－17.11,P=0.030), and biopsy ISUP grade(OR=1.97,95%CI=1.12－3.46, P=0.018)were independent risk factors for pelvic lymph node metastasis. The C-index of the prediction model was 0.834, which indicated that the model had a good prediction ability. The actual value of the model calibration curve and the prediction probability of the model fitted well, indicating that the model had a good accuracy. Further analysis of DCA curve showed that the model had good clinical application value when the risk threshold ranged from 0.05 to 0.70.Conclusion： For prostate cancer patients with PSA≤20 μg/L, bpMRI has a good predictive value for the pelvic lymph node metastasis of prostate cancer with extrocapusular extension, enlargement of pelvic lymph nodes and ISUP grade≥4.

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.

Background: and Purpose Symptomatic intracranial hemorrhage (sICH) following endovascular thrombectomy (EVT) is a severe complication associated with adverse functional outcomes and increased mortality rates. Currently, a reliable predictive model for sICH risk after EVT is lacking. Methods: This study used data from patients aged ≥20 years who underwent EVT for anterior circulation stroke from the nationwide Taiwan Registry of Endovascular Thrombectomy for Acute Ischemic Stroke (TREAT-AIS). A predictive model including factors associated with an increased risk of sICH after EVT was developed to differentiate between patients with and without sICH. This model was compared existing predictive models using nationwide registry data to evaluate its relative performance. Results: Of the 2,507 identified patients, 158 developed sICH after EVT. Factors such as diastolic blood pressure, Alberta Stroke Program Early CT Score, platelet count, glucose level, collateral score, and successful reperfusion were associated with the risk of sICH after EVT. The TREAT-AIS score demonstrated acceptable predictive accuracy (area under the curve [AUC]=0.694), with higher scores being associated with an increased risk of sICH (odds ratio=2.01 per score increase, 95% confidence interval=1.64–2.45, P<0.001). The discriminatory capacity of the score was similar in patients with symptom onset beyond 6 hours (AUC=0.705). Compared to existing models, the TREAT-AIS score consistently exhibited superior predictive accuracy, although this difference was marginal. Conclusions The TREAT-AIS score outperformed existing models, and demonstrated an acceptable discriminatory capacity for distinguishing patients according to sICH risk levels. However, the differences between models were only marginal. Further research incorporating periprocedural and postprocedural factors is required to improve the predictive accuracy.

Objective:To explore the clinical characteristics of pediatric kidney transplant recipients reinfected with SARS-CoV-2.Method:The relevant clinical data were retrospectively reviewed for 191 pediatric kidney transplant recipients at a single center. Based upon whether or not there was a reinfection of SARS-CoV-2, they were assigned into two groups of single infection (group A, 127 cases) and reinfection (group B, 64 cases). Baseline profiles, clinical symptoms, diagnostic and therapeutic strategies, markers of disease progression, immune status, respiratory support modalities, comorbidities and transplantation-related data were collected for comparing the inter-group differences during primary infection and between two infections in reinfected group.Result:As compared with group A, group B recipients had a higher proportion of age <12 years (71.9% vs 54.3%) ,unvaccinated (81.2% vs 66.1%) and such symptoms as high fever (34.4% vs 12.6% ), dry cough (43.8% vs 23.6% ) and chest tightness (14.1% vs 3.9 %) during primary infection (all P<0.05). During primary infection, the levels of IL-6 and CRP were higher in group B than in group A and inter-group difference was statistically significant (both P<0.01). The levels of IL-6 ( P<0.01), CRP ( P<0.01) and PCT ( P= 0.023) were lower in group B during reinfection than those during primary infection and the difference was statistically significant. During primary infection, the counts of CD3+, CD4+, CD8+, NK and B lymphocyte of group B were lower than those of group A. And inter-group differences were statistically significant (all P<0.01). During reinfection, the levels of CD3+, CD4+, CD8+, NK and B lymphocyte counts of group B spiked as compared with those of group A during primary infection and the differences were statistically significant (all P<0.01). The levels of SCr and UA in group B differed insignificantly before and after primary infection with SARS-CoV-2. However, the differences before and after reinfection were statistically significant (both P<0.01) . Conclusion:Symptomatic and immunocompromised pediatric KT recipients during primary infection with SARS-CoV-2 are more prone to reinfection during subsequent epidemics. Though mildly symptomatic, reinfection may exacerbate impairments of graft kidney function in pediatric KT recipients.

Objective:To explore the characteristic pathological manifestations of non-HLA antibodies after kidney transplantation (KT) and examine the differences of MFT values of non-HLA antibodies in different pathological manifestations.Methods:The study was conducted on KT recipients at the First Affiliated Hospital of Zhengzhou University from February 2021 to June 2023 with unexplained elevated serum creatinine. Patients undergoing pathological puncture and concurrent HLA antibody testing were included, focusing on those with DSA (MFI>4 000) and non-HLA antibody negativity. According to the detection results of non-HLA and HLA antibodies, they were assigned into two groups of non-HLA antibody positive (45 cases) and HLA-DSA positive (28 cases). Both non-HLA and HLA antibodies were detected by luminex single antigen microbeads, χ2, t or Mann-Whitney U nonparametric tests were utilized for examining the inter-group differences in pathological manifestations. The recipients with positive non-HLA antibodies were grouped according to the differential pathological features[microvascular inflammation group (22 cases) and non-microvascular inflammation group (23 cases), interstitial fibrosis group (39 cases) and non-interstitial fibrosis (9 cases) ]. MFI values of non-HLA antibodies were standardized and heat map was generated with R language ComplexHeatmap package. The differences of response values of non-HLA antibodies with different pathological manifestations were examined by rank-sum test. Results:The positive rates of microvascular inflammation were 48.9% (22/45) and 82.1% (23/28) in HLA-DSA positive and non-HLA antibody positive groups with statistical significance ( χ2=8.073, P=0.006). The positive rates of interstitial fibrosis in two groups were 80.8% (36/45) and 53.6% (15/28) and the difference was statistically significant ( χ2=5.726, P=0.021). The relative levels of anti-arachnotoxin receptor 1 (Latrophilin 1, LPHN1), keratin 8 (KRT8), keratin 18 (KRT18) and Sjogren's syndrome antigen B (SSB) were higher in microvascular inflammation group than those in non-microvascular inflammation group. The differences were statistically significant [559.50 (262.00, 801.25) vs 285.00 (183.00, 460.00), P=0.024; 504.50 (369.5, 725.25) vs 317.00 (231.50, 458.00), P=0.014; 672.50 (454.50, 969.50) vs 399.00 (246.50, 772.50), P=0.030; 967.50 (482.00, 2 066.50) vs 399.00 (246.50, 772.50), P=0.033]. The relative levels of anti-cyclic citrullinate peptide (CCP), colony-stimulating factor 2 (CSF2), intercellular adhesion molecule 1 (ICAM1) and collagen Ⅳ antibody were higher in interstitial fibrosis group than those in non-interstitial fibrosis group with statistical significance [100.00 (79.88, 167.50) vs 64.50 (37.00, 89.00), P=0.016; 146.25 (93.38, 244.75) vs 87.00 (66.00, 105.00), P=0.041; 132.50 (106.38, 229.50) vs 95.00 (55.00, 125.00), P=0.037; 432.50 (280.75, 653.75) vs 208.00 (192.00, 301.00), P=0.028]. Conclusions:As compared with HLA-DSA, the characteristic pathological manifestations of non-HLA antibodies post-KT include a lower incidence of microvascular inflammation and a higher incidence of interstitial fibrosis. For non-HLA antibody response values of characteristic pathological manifestations, the expressions of different non-HLA antibodies vary statistically.

The biological clock(also known as the circadian rhythm)is the fundamental reliance for all organisms on Earth to adapt and survive in the Earth's rotation environment.Circadian rhythm is the most basic regulatory mechanism of life activities,and plays a key role in maintaining normal physiological and biochemical homeostasis,disease occurrence and treatment.Recent studies have shown that the biologi-cal clock plays an important role in the development of oral tissues and in the occurrence and treatment of oral diseases.Since there is cur-rently no guiding literature on the research methods of biological clock in stomatology,researchers mainly conduct research based on pub-lished references,which has led to controversy about the research methods of biological clock in stomatology,and there are many confusions about how to rationally apply the research methods of circadia rhythms.In view of this,this expert consensus summarizes the characteristics of the biological clock and analyzes the shortcomings of the current biological clock research in stomatology,and organizes relevant experts to summarize and recommend 10 principles as a reference for the rational implementation of the biological clock in stomatology research.

Non-alcoholic fatty liver disease(NAFLD)is a kind of disease caused by a variety of reasons,which is characterized by steatosis and fat accumulation in liver parenchymal cells.In recent years,the morbidity of NAFLD has been relatively high in China.In the field of traditional Chinese medicine,NAFLD can be classified into the categories of"hepatic mass","abdominal mass"and"concretions and conglomerations".Spleen failing in transportation is the core pathogenesis of NAFLD,and the intervention of NAFLD with the method of activating spleen and resolving accumulation(shortened to Yunpi Huaji method)has achieved good results.In this paper,the clinical research of Yunpi Huaji method for the treatment of NAFLD and experimental research on its therapeutic mechanism in the past 10 years were reviewed.The results showed that the treatment of NAFLD by Yunpi Huaji method can be achieved by oral use of compound preparations and external treatment such as acupuncture,tuina and physiotherapy,and the therapeutic mechanism in the prevention and treatment of NAFLD was through multi-action,multi-target and multiple signaling pathways.The review will provide thoughts for the clinical diagnosis and treatment of NAFLD in traditional Chinese medicine,and will supply theoretical support for the medicine development and mechanism exploration of Yunpi Huaji method for the prevention and treatment of NAFLD.
