Objective To evaluate the effectiveness of thermal tomography in breast cancer (BC) screening. Methods We conducted a general population-based BC screening in three regions of Hubei Province (Xiantao, Hongan, and Yangxin Districts). Participants underwent a questionnaire-based interview for baseline data collection. They then received a physical examination, thermal tomography, and ultrasound from doctors and technicians. We compared the efficacies, including sensitivity, specificity, and false-positive rates, of ultrasound and thermal tomography in BC screening. Results A total of 59 712 eligible women were included in this screening program. The BI-RADS 1, 2, 3, 4, and 5 accordance rates between the two screening methods were 0.9549, 0.8047, 0.9037, 0.3352, and 0, respectively. The overall accordance rate was 0.933 1. The kappa consistency results showed that the Cicchetti-Allison and Fleiss-Cohen kappa values were 0.7970 and 0.8583, respectively. Although the two methods had equal sensitivities, specificity was higher in thermal tomography than in ultrasound. The false-positive rate was lower in thermal tomography than in ultrasound. The area under the receiver operating characteristic (ROC) curve of thermal tomography was significantly larger than that of ultrasound. Conclusion The general consistency between thermal tomography and ultrasound in BC screening was high. Thermal tomography outperformed ultrasound in terms of specificity and diagnostic efficiency. Therefore, thermal tomography has a high application value for general population-based BC screening.

Radiochemotherapy-induced oral mucositis (OM) is a common oral complication in patients with tumors following head and neck radiotherapy or chemotherapy. Erosion and ulcers are the main features of OM that seriously affect the quality of life of patients and even the progress of tumor treatment. To date, differences in clinical prevention and treatment plans for OM have been noted among doctors of various specialties, which has increased the uncertainty of treatment effects. On the basis of current research evidence, this expert consensus outlines risk factors, clinical manifestations, clinical grading, ancillary examinations, diagnostic basis, prevention and treatment strategies and efficacy indicators for OM. In addition to strategies such as basic oral care, anti-inflammatory and analgesic agents, anti-infective agents, pro-healing agents, and photobiotherapy recommended in previous guidelines, we also emphasize the role of traditional Chinese medicine in OM prevention and treatment. This expert consensus aims to provide references and guidance for dental physicians and oncologists in formulating strategies for OM prevention, diagnosis, and treatment, standardizing clinical practice, reducing OM occurrence, promoting healing, and improving the quality of life of patients.

Objective To evaluate the efficacy of human papillomavirus E6/E7(HPV E6/E7)mRNA combined with colposcopy in screening cervical cancer and precancerous lesions.Methods A total of 480 patients with suspected cervical precancerous lesions in the hospital from July 2022 to De-cember 2024 were retrospectively selected as research objects.All the patients underwent HPV E6/E7 mRNA testing,colposcopy,and pathological examination.Taking the pathological examination results as the diagnostic golden standard,the diagnostic values of HPV E6/E7 mRNA and colposcopy alone as well as their combination were analyzed.Results The pathological examination results of 480 pa-tients showed that there were 192 negative cases,including 1 case of normal cervix and 191 cases of benign lesions;there were 288 positive cases,including 133 cases of low-grade squamous intraepithe-lial lesions(LSIL),110 cases of high-grade squamousintraepithelial lesions(HSIL),and 45 cases of cervical squamous cell carcinoma(SCC).The colposcopy results showed 211 true-positive cases and 138 true-negative cases;the HPV E6/E7 mRNA test results showed 199 true-positive cases and 137 true-negative cases;the combined test results showed 239 true-positive cases and 174 true-negative cases.The sensitivity(95.22％),specificity(75.98％),accuracy(86.04％),positive predic-tive value(81.29％),and negative predictive value(93.55％)of the combined test were signifi-cantly higher than those of each individual test(P＜0.001).Moreover,the consistency between the combined test and pathological results(Kappa=0.718,P＜0.001)was also significantly high-er than that of each individual test.Conclusion Compared with HPV E6/E7 mRNA or colposcopy alone,the combined test has higher clinical application value in screening of cervical precancerous lesions and cervical cancer,shows stronger consistency with pathological results,and is of great sig-nificance for the early differential diagnosis of cervical precancerous lesions and cervical cancer.

Objective:To investigate the clinical efficacy and safety of deep hyperthermia combined with sintilimab and nab-PC (albumin-bound paclitaxel + carboplatin) regimen in the treatment of advanced squamous non-small cell lung cancer (NSCLC) with driver gene negative and programmed death-1 receptor ligand 1 (PD-L1) expression positive.Methods:A prospective case-control study was performed. A total of 84 advanced squamous NSCLC patients with driver gene negative and PD-L1 expression positive in Hebei Seventh People's Hospital from January 2020 to December 2022 were collected, and all patients were divided into the observation group and the control group according to the random number table method, with 42 cases in each group. The control group was given the treatment of sintilimab combined with nab-PC regimen, and the observation group was given deep hyperthermia on the basis of the control group. After 4 consecutive cycles of treatment, the short-term efficacy of the two groups was compared. The levels of serum tumor markers [carcinoembryonic antigen (CEA), squamous cell carcinoma antigen (SCCA), cytokeratin fragment 19 (CYFR21-1)], and the positive expression rates of immunohistochemistry markers [p40, p63, and cytokeratin 5/6 (CK5/6)] before and after treatment were compared between two groups. Functional Assessment of Cancer Therapy-Lung cancer module (FACT-L) scores, the adverse reactions and the long-term survival of the two groups were compared.Results:There were 26 males and 16 females in the observation group, and the age was (59±11) years; there were 22 males and 15 females in the control group, and the age was (58±11) years. The objective remission rate and the disease control rate were 71.43% (30/42), 90.48% (38/42), respectively in the observation group, and 50.00% (21/42), 80.95% (34/42), respectively in the control group; the objective remission rate in the observation group was higher than that in the control group, and the difference was statistically significant ( χ2 = 4.04, P = 0.044); and there was no statistically significant difference in the disease control rate of both groups ( χ2 = 1.56, P = 0.212). The levels of serum CEA, SCCA and CYFRA21-1, and the positive expression rates of p40, p63, and CK5/6 in the two groups after treatment were lower than those before treatment (all P < 0.05); and the scores of physiological status, functional status, additional concern in FACT-L scores and the total score of the scale after treatment were higher than those before treatment (all P < 0.05). There were no statistically significant differences in the incidence of adverse reactions including thrombocytopenia, neutropenia, leukopenia, anemia, fever of the two groups (all P > 0.05). The median progression-free survival (PFS) time was 6.5 months (95% CI: 3.82-12.75), 5.1 months (95% CI: 3.14-12.26),respectively in the observation group and the control group, and the difference in the median PFS time was statistically significantly of both groups ( χ2 = 4.21, P = 0.040). The median overall survival (OS) time was 12.9 months (95% CI: 6.25-15.46), 9.7 months (95% CI: 4.74-13.02), respectively in the observation group and the control group, and the difference in the median OS time was statistically significantly of both groups ( χ2 = 4.43, P = 0.035). Conclusions:Deep hyperthermia combined with sintilimab and nab-PC regimen in the treatment of advanced squamous NSCLC with driver gene negative and PD-L1 expression positive can effectively reduce the serum tumor markers levels and positive expression rate of immunohistochemical markers, improve the quality of life of patients, and increase the short-term and long-term efficacy.

[Abstract] [Objective] To compare and analyze the efficacy of platelet transfusion in patients with different doses, and to analyze the risk factors for platelet transfusion refractoriness. [Methods] A total of 5 827 patients who received platelet transfusion in the PLA General Hospital from May 2023 to May 2024 were selected as the research subjects, among which 4 780 patients were transfused with 1 therapeutic dose of platelets, and 1 047 patients were transfused with 0.5 therapeutic dose of platelets, and the efficacy of platelet transfusion was compared between the two groups. The effects of gender, disease type, white blood cell count before transfusion, fever, number of platelet transfusions, and platelet antibodies on platelet transfusion refractoriness were analyzed using univariate analysis, and the independent risk factors affecting platelet transfusion refractoriness were further analyzed by multivariate logistic regression. [Results] Among 4 780 patients, 3553 (74.3%) were effective and 1 227 (25.7%) were ineffective. Among 1 047 patients, 0.5 platelet infusion was effective in 755 cases (72.1%) and ineffective in 292 cases (27.9%). There was no significant difference in the effective rate of platelet transfusion between the two groups (P>0.05). Univariate analysis showed that the therapeutic effect of platelet transfusion was related to age, the number of platelet transfusion, disease type, platelet antibodies and white blood cell count before transfusion (P<0.05), while age, gender, fever and blood type were not related to the therapeutic effect of platelet transfusion (P>0.05). The results of multi-factor analysis showed that age, white blood cell count >50×10⁹/L, platelet transfusion times, disease type and platelet antibody were independent risk factors for ineffective transfusion (P<0.05). [Conclusion] There is no significant difference in the efficacy of platelet infusion with 0.5 therapeutic dose or 1 therapeutic dose. In addition, age, white blood cell count >50×10⁹/L, the number of platelet transfusion, disease type and platelet antibodies were the factors affecting the ineffective platelet transfusion in group 2.

ObjectiveTo develop traditional Chinese medicine （TCM） formulae for the treatment of nonsevere coronavirus disease 2019 （COVID-19） and to explore its anti-inflammatory mechanism. MethodsThe dysregulated signaling pathways were determined in macrophages from bronchoalveolar lavage fluid of COVID-19 patients and in lung epithelial cells infected with SARS-CoV-2 in vitro based on transcriptome analysis. A total of 102 TCM formulae for the clinical treatment of nonsevere COVID-19 were collected through literature. The pathway-reversing rates of these formulae in macrophages and lung epithelial cells were evaluated based on signature signaling pathways， and the basic formula was determined in conjunction with TCM theory. The commonly used Chinese materia medica for nonsevere COVID-19 were summarized from the 102 TCM formulae as abovementioned. And together with the screening results from the Pharmacopoeia of the People's Republic of China， a “Chinese materia medica pool” was esta-blished for the development of TCM formulae for COVID-19. The regulatory effects of each herb on signaling pathways were obtained based on targeted transcriptome analysis. Oriented at reversing dysregulated signaling pathways of COVID-19， the calculation was carried out， and the artificial intelligent methods for compositing formulae， that are exhaustive method and parallel computing， were used to obtain candidate compound formulas. Finally， with reference to professional experience， an innovative formula for the treatment of nonsevere COVID-19 was developed. The ethanol extract of the formula was evaluated for its anti-inflammatory effects by detecting the mRNA expression of interleukin 1b （Il1b）， C-X-C motif chemokine ligand 2 （Cxcl2）， C-X-C motif chemokine ligand 10 （Cxcl10）， C-C motif chemokine ligand 2 （Ccl2）， nitric oxide synthase 2 （Nos2）， and prostaglandin-endoperoxide synthase 2 （Ptgs2） using reverse transcription-quantitative polymerase chain reaction （RT-qPCR） in RAW264.7 cells treated with lipopolysaccharide （LPS）. ResultsIn macrophages and lung epithelial cells， 34 dysregulated signaling pathways associated with COVID-19 were identified respectively. The effects of the 102 formulae for clinical treatment of nonsevere COVID-19 were evaluated based on the dysregulated signaling pathways and targeted transcriptome， and the result showed that Yinqiao Powder and Pingwei Powder （银翘散合平胃散， YQPWP） ranked first， reversing 91.18% of the dysregulated signaling pathways in macrophages and 100% of the dysregulated signaling pathways in lung epithelial cells. Additionally， YQPWP had the function of scattering wind and clearing heat， resolving toxins and removing dampness in accordance with the pathogenesis of wind-heat with dampness in COVID-19. It was selected as the basic formula， and was further modified and optimized to develop an innovative fomula Qiaobang Zhupi Yin （翘蒡术皮饮， QBZPY） based on expert experience and artificial intelligence in composing formulae. QBZPY can reverse all the dysregulated signaling pathways associated with COVID-19 in macrophages and lung epithelial cells， with the reversing rates of 100%. The chief medicinal of QBZPY， including Lianqiao （Fructus Forsythiae）， Xixiancao （Herba Siegesbeckiae） and Niubangzi （Fructus Arctii）， can down-regulate multiple signaling pathways related with virus infection， immune response， and epithelial damage. RT-qPCR results indicated that compared with the model group， the QBZPY group down-regulated the mRNA expression of Il1b， tumor necrosis factor （Tnf）， Cxcl2， Cxcl10， Ccl2， Nos2 and Ptgs2 induced by LPS in RAW264.7 cells （P＜0.05 or P＜0.01）. ConclusionBased on targeted transcriptome analysis， expert experience in TCM and artificial intelligence， QBZPY has been developed for the treatment of nonsevere COVID-19. The ethanol extract of QBZPY has been found to inhibit mRNA expression of several pro-inflammatory genes in a cellular inflammation model.

Objective·To analyze the clinicopathologic characteristics,gene mutation profile,and prognostic factors of thyroid diffuse large B-cell lymphoma(DLBCL).Methods·From November 2003 to December 2021,a total of 66 patients with thyroid DLBCL[23 cases(34.8%)with primary thyroid DLBCL,and 43 cases(65.2%)with secondary thyroid DLBCL]admitted to Ruijin Hospital,Shanghai Jiao Tong University School of Medicine were retrospectively analyzed for their clinicopathological data,survival and prognostic factors.Gene mutation profiles were evaluated by targeted sequencing(55 lymphoma-related genes)in 40 patients.Results·Compared to primary thyroid DLBCL,secondary thyroid DLBCL had advanced ratio of Ann Arbor stage Ⅲ?Ⅳ(P=0.000),elevated serum lactate dehydrogenase(LDH)(P=0.043),number of affected extranodal involvement≥2(P=0.000),non-germinal center B cell(non-GCB)(P=0.030),BCL-2/MYC double expression(DE)(P=0.026),and international prognostic index(IPI)3?5-scores(P=0.000).The proportion of patients who underwent thyroid surgery(P=0.012)was lower than that of patients with primary thyroid DLBCL.The complete remission(CR)rate in primary thyroid DLBCL patients was higher than that in secondary thyroid DLBCL patients(P=0.039).Fifty-five patients(83%)received rituximab combined with cyclophosphamide,doxorubicin,vincristine,and prednisone(R-CHOP)-based first-line regimen.The estimated 5-year progression free survival(PFS)rate of primary thyroid DLBCL patients was 95.0%,higher than the 49.7%of the secondary patients(P=0.010).Univariate analysis showed that Ann Arbor Ⅲ?Ⅳ(HR=4.411,95%CI 1.373?14.170),elevated LDH(HR=5.500,95%CI 1.519?19.911),non-GCB(HR= 5.291,95%CI 1.667?16.788),and DE(HR=6.178,95%CI 1.813?21.058)were adverse prognostic factors of PFS in patients with thyroid DLBCL.Ann Arbor Ⅲ?Ⅳ(HR=7.088,95%CI 0.827?60.717),elevated LDH(HR=6.982,95%CI 0.809?60.266),and DE(HR=18.079,95%CI 1.837?177.923)were adverse prognostic factors of overall survival(OS).Multivariate analysis showed that Ann Arbor Ⅲ?Ⅳ(HR=4.693,95%CI 1.218?18.081)and elevated LDH(HR=5.058,95%CI 1.166?21.941)were independent adverse prognostic factors of PFS in patients with thyroid DLBCL.Targeted sequencing data showed mutation frequency>20%in TET2(n=14,35%),KMT2D(n=13,32%),TP53(n=11,28%),GNA13(n=10,25%),KMT2C(n=9,22%),and TP53 were adverse prognostic factors of PFS in patients with thyroid DLBCL(P=0.000).Conclusion·Patients with primary thyroid DLBCL have better PFS and OS than those with secondary thyroid DLBCL.Ann Arbor Ⅲ?Ⅳ,elevated LDH,non-GCB,and DE(MYC and BCL2)are adverse prognostic factors in thyroid DLBCL.TET2,KMT2D,TP53,GNA13,and KMT2C are commonly highly mutated genes in thyroid DLBCL,and the prognosis of patients with TP53 mutations is poor.

Objective:To investigate the clinical and electrophysiological characteristics of patients with amyotrophic lateral sclerosis (ALS) with positive repetitive nerve stimulation (RNS) test results on the accessory nerve and negative needle electromyography (EMG) test results on the sternocleidomastoid with the goal to enrich the knowledge of disease progression in patients with ALS.Methods:The clinical data of 612 patients diagnosed with ALS at the Neurology Department of the First Medical Center, Chinese PLA General Hospital from June 2016 to August 2022 were collected. In total, 267 cases had undergone EMG tests on the sternocleidomastoid following a positive 3 Hz RNS test result on the accessory nerve, who were selected as the study subjects. The differences in clinical indicators were compared between RNS (+)/EMG (-) group and RNS (+)/EMG (+) group. A binomial distribution model with multiple variables was built to quantitatively analyze the major factors and their effects.Results:At the initial visit, 15.8% of patients with ALS were 3 Hz RNS (+) on the accessory nerve and EMG (-) on the ipsilateral sternocleidomastoid, accounting for 36.3% of RNS (+) patients. The decremental range of the 3 Hz RNS test delivered to the accessory nerve in these patients [-14% (-19%, -12%)] was lower than that in patients with RNS (+)/EMG (+) [-17% (-23%, -13%)] ( P<0.05), while the ratio of upper limb onset (64.9%) and non-definite diagnosis (28.9%) were higher [54.7% and 13.5% for patients with RNS (+)/EMG (+), P<0.05]. Furthermore, the Revised Amyotrophic Lateral Sclerosis Functional Rating Scale (ALSFRS-R) score [40 (37, 42)], body mass index (BMI) [23.8 (22.0, 25.4) kg/m 2] and forced vital capacity (FVC) [92.8% (76.6%, 103.8%)] were higher in patients with RNS(+)/EMG(+) ( P<0.05). The multivariate model suggested that, in patients with RNS (+)/EMG (-), the ratio of upper limb onset to lower limb onset was 1.04, while that of upper limb onset to bulbar onset was 2.02, and that of lower limb onset to bulbar onset was 1.94. The ratio of non-definite ALS to definite ALS was 1.13. The ALSFRS-R score, BMI, and FVC had a protective contribution to the electrophysiological function of the motor neurons. The ratio of the effect size of the ALSFRS-R or BMI to that of FVC was 3.37 and 1.14, respectively. Conclusions:Patients with ALS that were 3 Hz RNS (+) on the accessory nerve and EMG (-) on the ipsilateral sternocleidomastoid had a smaller decremental range of the compound muscle action potential amplitude, and a higher proportion of upper limb onset and non-definite ALS. A higher ALSFRS-R score, BMI, and FVC have a protective effect to the electrophysiological function of motor neurons. The effect size of the ALSFRS-R score is the largest, followed by BMI and FVC.

Objective·To analyze the clinicopathologic characteristics of patients with kidney-involved diffuse large B-cell lymphoma(DLBCL),including clinical characteristics,pathological characteristics,gene mutation profiles,and prognostic factors.Methods·One hundred and forty-nine patients with kidney-involved DLBCL,admitted to Ruijin Hospital,Shanghai Jiao Tong University School of Medicine from July 2005 to November 2021,were retrospectively analyzed for their clinicopathological data,survival and prognostic factors,which included therapeutic methods,clinical outcomes,staging,etc.Gene mutation profiles were evaluated by targeted sequencing of 54 lymphoma-related genes.Prognostic factors were also analyzed based on the information mentioned above.Results·A total of 149 kidney-involved DLBCL cases were included,of which 89 patients(58.4%)were aged over sixty,121 patients(81.2%)were staged Ann Arbor Ⅲ?Ⅳ,27 patients(18.1%)had an Eastern Cooperative Oncology Group(ECOG)performance status of two or more,121 patients(81.2%)had elevated serum lactate dehydrogenase(LDH)level,111 patients(74.5%)had extranodal invasion in at least two organs and 131 patients(87.9%)scored over 2 points on the international prognosis index(IPI).The estimated 5-year overall survival(OS)rate and progression-free survival(PFS)rate of kidney-involved DLBCL patients were 52.2%and 50.4%respectively.Univariate analysis revealed that elevated serum LDH levels were an adverse prognostic factor for both OS(P=0.048)and PFS(P=0.033).In pathological characteristics,145 patients(97.3%)belonged to DLBCL,not otherwise specified(NOS)and 39 patients(26.3%)belonged to germinal center B-cell(GCB)according to Hans classification.Among 144 patients who could be evaluated for clinical outcomes,87 patients(60.4%)got complete response(CR).Targeted sequencing data from 75 kidney-involved DLBCL patients showed high mutation frequency in PIM1(n=23,31%),MYD88(n=22,29%),CD79B(n=21,28%)and KMT2D(n=18,24%),with CD79B mutation indentified as an adverse prognostic factor for OS in patients with kidney-involved DLBCL(P=0.034).Conclusion·Elevated serum LDH level is an adverse prognostic factor in patients with kidney-involved DLBCL.The prognosis of patients with CD79B mutations is poor.

Objectives:To investigate the clinical value of contrast echocardiography in the detection of right heart space-occupying lesions. Methods:The imaging and clinical data of 39 patients with right heart space-occupying lesions confirmed by surgery,pathology and clinical treatment in Yanbian University Hospital from January 2019 to January 2023 were retrospectively analyzed.All patients underwent contrast echocardiography and cardiac magnetic resonance(CMR)examinations.The contrast echocardiography features of right heart neoplastic from non-neoplastic occupying lesions were summarized.The diagnostic efficacy of contrast echocardiography and CMR in right heart space-occupying lesions was compared. Results:Among the 39 patients,12 patients(30.8%)were confirmed as thrombus and vegetation,6 patients(15.4%)as benign tumors and 21 patients(53.8%)as malignant tumors.There were 8,4,4 and 17 patients of thrombus,vegetation,benign tumor and malignant tumors located in right atrium,respectively.Contrast echocardiography was used to diagnose thrombus and vegetation in 12 patients(30.8%),benign tumors in 5 patients(12.8%),malignant tumors in 22 patients(56.4%).CMR was used to diagnose thrombus and vegetation in 18 patients(46.2%),benign tumors in 5 patients(12.8%),malignant tumors in 16 patients(41.0%).The Kappa coefficient between contrast echocardiography and clinical diagnosis was 0.956(P<0.001).The Kappa coefficient between CMR and clinical diagnosis was 0.754(P<0.001). Conclusions:Contrast echocardiography can dynamically observe the degree of vascularization in the lesion tissue in real-time,accurately distinguishing the nature of the right heart space-occupying lesions.
