Objective:To explore the influencing factors for pathological upgrading in prostate cancer patients with a Gleason score of 3 + 3 undergoing targeted biopsy，and to establish a nomogram prediction model.Methods:A retrospective analysis was conducted on 191 patients with localized prostate cancer diagnosed with a Gleason score of 3 + 3 through targeted biopsies at the First Affiliated Hospital of Nanjing Medical University from January 2020 to June 2024. The age of the patients was 67（61，73）years，with prostate-specific antigen（PSA）level of 7.44（5.53，10.19）ng/ml，prostate volume of 35.64（26.59，48.97）ml，and PSA density（PSAD）of 0.20（0.14，0.31）ng/ml 2. Among them，61 cases（31.94%）had a Prostate Imaging Reporting and Data System（PI-RADS）score of 3，104 cases（54.45%）had a score of 4，and 26 cases（13.61%）had a score of 5. The diameter of the main lesion was 10.75（7.86，14.00）mm. The lesions were located in the peripheral zone in 78 cases（40.84%），the transition zone in 99 cases（51.83%），and the anterior fibromuscular stroma in 14 cases（7.33%）. The lesions were found at the apex in 56 cases（29.32%），in the body in 120 cases（62.83%），and at the base in 15 cases（7.85%）. MRI revealed only one lesion with a PI-RADS score ≥ 3 in 131 cases，two suspected lesions in 43 cases，three suspected lesions in 12 cases，and four suspected lesions in 5 cases. Systematic biopsy was positive in 121 cases（63.4%）and negative in 70 cases（36.6%）. The lesions were confined to the left lobe in 63 cases（32.98%），right lobe in 68 cases（35.60%），and involved both lobes in 60 cases（31.41%）. The interval between biopsy and surgery was 9.0（7.0，14.0）days. Univariate analyses were performed using Mann-Whitney U tests or χ2 tests，and multivariate logistic regression was used to identify independent predictors of pathological upgrading. A nomogram model was constructed based on these independent predictors. The model’s discriminative ability was assessed using the area under the receiver operating characteristic（ROC）curve（AUC），and internal validation of the model’s consistency was conducted using the bootstrap resampling method. Decision curve analysis（DCA）was performed to assess clinical utility. Results:Among the 191 cases，60（31.4%）had no pathological upgrading after surgery，while 131（68.6%）showed upgrading. Univariate analysis showed that the maximum diameter of the main lesion［9.0（6.0，13.2）mm vs. 11.0（8.4，14.0）mm］，number of suspicious lesions on MRI［1.0（1.0，1.0）vs. 1.0（1.0，2.0）］，number of positive systematic biopsy cores［1.0（0，2.0）vs. 1.0（0，3.0）］，percentage of positive systematic biopsy cores［0.08（0，0.17）vs. 0.12（0，0.25）］，number of positive targeted biopsy cores［2.0（1.0，3.0）vs. 3.0（1.0，4.0）］，percentage of positive targeted biopsy cores［0.37（0.24，0.75）vs. 0.50（0.38，0.85）］，level of the index lesion，location of the index lesion，and PI-RADS score were associated with pathological upgrading（ P < 0.05）. Multivariate logistic regression analysis showed that PI-RADS score 4（ OR = 5.88，95% CI 2.41 - 14.35），number of suspicious lesions on MRI（ OR = 4.15，95% CI 1.88 - 9.17），location of the index lesion in the transition zone（ OR = 6.86，95% CI 2.81 - 16.73），and percentage of positive targeted biopsy cores（ OR = 4.37，95% CI 1.38 - 14.90）were independent risk factors for pathological upgrading（ P < 0.05）. The nomogram model constructed using these predictors had an AUC of 0.845. Internal validation using the Bootstrap method yielded an AUC value of 0.812，indicating high predictive accuracy of the model. The calibration curve indicated good calibration. Decision curve analysis showed that the threshold range for net benefit in the model was between 12% - 100%. Conclusions:The PI-RADS score 4，the number of lesions with PI-RADS ≥ 3，the location of the main lesion in the transition zone，and the percentage of positive needles in targeted biopsy are independent risk factors for pathological upgrading from Gleason score 3 + 3. The nomogram model constructed from these factors demonstrates good predictive performance and provides a reference for clinical decision-making.

Objective To investigate the effects of Aurora kinase A(AURKA)on the tumor microenvironment of colorectal cancer(CRC)and to predict the active compounds in Chinese herbs that can target AURKA.Methods Based on the transcriptomic data and clinical information from 380 CRC tissues and 51 paracancerous tissues in The Cancer Genome Atlas(TCGA)database,the infiltration of different cells in the tumor tissues was analyzed using xCell and the binding of active compounds of Chinese herbs with AURKA was predicted through molecular docking.Results The expression of AURKA was significantly upregulated in CRC tissues compared with that in paracancerous tissues(P＜0.05),and CRC patients with high AURKA expression had shorter overall survival.Compared with the AURKA low-expression group,the abundance of macrophages,monocytes,and effector memory CD4+and CD8+T cells was significantly downregulated in the AURKA high-expression group(P＜0.05).In addition,the cytotoxicity of T cells was significantly reduced(P＜0.05).Further analysis revealed that AURKA expression was positively correlated with the abundance of myeloid-derived suppressor cells(MDSCs)and the expression levels of their chemokines CXCL2 and CXCL5(P＜0.05).Genes that were differentially expressed between the AURKA high-and low-expression groups were mainly enriched in monocyte migration,chemokine-induced cellular responses,and other related processes.Chinese herbal compounds,including hesperidin,aristololactam A Ⅱ a,anacardic acid,coumestrol,and 17β-estradiol,all showed binding energies to AURKA lower than-1.2 kcal/mol,indicating a certain level of binding stability.Among these Chinese herbal compounds,17β-estradiol exhibited the best binding stability to AURKA-3UOL.Conclusion The high expression of AURKA in CRC tissues suggests a poor clinical prognosis.AURKA can promote the development of a suppressive immune microenvironment in CRC,and 17β-estradiol,an active compound from Chinese herbs,is a potential therapeutic agent targeting AURKA.

A retrospective analysis was conducted on 5 516 patients diagnosed with prostate cancer(PCa) at our hospital. Among these, 52 patients aged ≤ 50 years were defined as the early-onset group.For the control group, 228 patients aged >50 years were randomly selected at a ratio of 1∶4.4. The early-onset group predominantly presented with elevated PSA levels at diagnosis and had a lower positive rate of digital rectal examination. There were no significant differences in clinical and pathological characteristics between the early-onset group and the control group. Young PCa patients in the low to intermediate risk categories had similar survival prognosis to older patients. However, young patients with high-risk prostate cancer had 5-year progression-free survival rate of 38.4% compared to 55.6% for older patients, and 5-year cancer-specific survival rate of 70.1% compared to 84.1% for older patients, indicating that high-risk young patients exhibited poorer oncological outcomes.

BACKGROUND: The treatment mode of lung cancer is epidermal growth factor receptor-tyrosine kinase inhibitors (EGFR-TKIs) as a first-line treatment for patients with EGFR mutant in non-small cell lung cancer (NSCLC). At the same time programmed death receptor 1 (PD-1) and its programmed death receptor ligand 1 (PD-L1) inhibitors therapy as the representative immune checkpoint inhibitors (ICIs) has a significant effect in the treatment of lung cancer. The aim of this study was to investigate the correlation between the expression of PD-1 and PD-L1 in NSCLC and clinicopathologic feature, EGFR gene mutation. METHODS: The protein expression of PD-1 and PD-L1 was detected by immunohistochemistry from 127 patients with NSCLC and EGFR gene mutation was detected by quantitative polymerase chain reaction (qPCR) to analyze its relation with clinicopathologic feature. Also, the correlation between protein expression of PD-1 and PD-L1 and EGFR mutation. RESULTS: The PD-1 positive expression in NSCLC tumor cells and tumor infiltrating immune cells is 53.5% (68/127), PD-L1 is 57.5% (73/127). The PD-1 and PD-L1 expression significantly higher in well-differentiated and moderately-differentiated carcinoma than poorly differentiated carcinoma, I+II than III+IV in clinical staging (P<0.05). The EGFR mutation rate was 46.5% (59/127), correlate with female, without smoking history, adenocarcinoma and well-differentiated and moderately-differentiated patients respectively higher than male, smoking history, squamous carcinoma and poorly differentiated patients (P<0.05). The protein expression of PD-L1 and PD-1 had the consistency in NSCLC patients (kappa=0.107,5, P=0.487). There was a negative correlation between the EGFR mutation and PD-1 and PD-L1 expression (Φ=-0.209, Φ=-0.221, P<0.05). Follow-up of NSCLC patients, the median total survival in under the age of 65, adenocarcinoma, well-differentiated and moderately-differentiated, with PD-L1 expression patients respectively higher than over the age of 65, squamous carcinoma, poorly differentiated, without PD-L1 expression patients (P<0.05). The median survival of hypo expression patients of PD-L1 significantly higher than hyper expression patient (P=0.04). CONCLUSIONS According to the Chinese Expert Consensus on Standards of PD-L1 immunohistochemistry testing for NSCLC, we tested the PD-L1 expression in NSCLC and then the dominant population of anti-PD-1/PD-L1 treatment was screened out. Patients with EGFR mutation were also detected and EGFR mutation was negatively correlated with the expression of PD-1 and PD-L1 as well. On the basis of PD-L1 expression and EGFR mutation status, it may benefit NSCLC patients from individualized treatment. Meanwhile, patients who were under the age of 65, adenocarcinoma, well-differentiated and moderately-differentiated, hypo expression of PD-L1 have a relatively good prognosis, to provide reference for the prognosis evaluation of NSCLC.

Objective:To explore the application value of neuro-linguistic programming (NLP) in psychological intervention for patients with cervical cancer.Methods:Totally 86 patients receiving chemotherapy for cervical cancer in Henan Provincial People's Hospital from July 2015 to December 2017 were selected by convenient sampling and divided into the observation group ( n=43) and the control group ( n=43) according to the random number table. Patients in the control group received conventional psychological intervention, while patients in the observation group received psychological intervention guided by NLP on this basis. The Symptom Checklist-90 (SCL-90) , Medical Coping Modes Questionnaire (MCMQ) and 36-Item Short Form Survey Instrument (SF-36) were used to evaluate the status, coping style and quality of life, and compare the compliance of the two groups of patients 3 months before and after intervention. Results:The SCL-90 scores in somatization, interpersonal sensitivity, anxiety and depression of the observation group were lower than those of the control group after intervention, and the differences were statistically significant ( P<0.05) . The MCMQ score in facing of the observation group was higher than that of the control group, while the scores in avoidance and yield of the observation group were lower than those in the control group, and the differences were statistically significant ( P<0.05) . The compliance of the observation group was better than that of the control group, and there was statistically significant difference between the two groups ( P<0.05) . Conclusions:NLP can ameliorate the negative emotions of patients with cervical cancer, change their coping styles, improve their treatment compliance and quality of life, which is of clinical significance.

Objective To survey the current status of professional value among health workers in grass-roots medical institutions of Wenzhou city and to analyze the influencing factors.Methods A survey on professional value was conducted from October to December 2017 among health workers from 14 primary medical institutions in 4 urban districts of Wenzhou City selected by stratified random sampling method.The self-designed questionnaires were used for the survey.A total of 350 questionnaires were distributed and 331 were returned,of which 302 were valid.The status and influencing factors of professional value were analyzed.Results The overall score of professional value was (96.66 ± 14.94).The univariate analysis showed that the professional value scores were associated with educational level (F=3.851),income(F=2.660),professional title(F=8.030),position(F=11.658) and specialty (F=4.667) of the health workers(all P＜0.05).The multivariate analysis showed that the gender(male:OR=0.53,95％ CI:-1.077--0.192,P=0.005),educational level (high school and below:OR=3.06,95％ CI:0.007-2.233,P=0.049),income (2 000-4 000 Yuan:OR=0.07,95％ CI:-4.783-0.627,P=0.011),professional title (no title:OR=0.27,95％CI:-2.397--0.232,P=0.017;Junior title:OR=0.31,95％CI:-2.197--0.153),P--0.024;intermediate title:OR=0.23,95％ CI:-2.533--0.366,P--0.009),position (doctor:OR=0.13,95％ CI:-3.235--0.815,P=0.001;nurse:OR=0.20,95％ CI:-2.883--0.368,P=0.011;technician:OR=0.15,95％ CI:-3.076--0.723,P=0.002)were influencing factors of professional value(all P＜0.05).Conclusion The professional values among health workers in Wenzhou grass-roots medical institutions are relatively low.The male gender,low educational level,low income,low professional title or no title and positions are influencing factors of professional value.

Objective To investigate the clinical value of combination of transvaginal fourdimensional hysterosalpingo-contrast sonography(TVS 4D-HyCoSy) with uterine tubal liquid poking in assessment tubal fimbria patency.Methods Sixty-two female infertile patients with obstruction at tubal fimbria,or partial obstruction with pelvic adhesion were included.All of them were underwent 4D-HyCoSy as well as uterine tubal liquid poking,and were followed with laparoscopic chromopertubation (LPC) using Methylene blue in three months.Results Comparing with laparoscopy,the total coincidence rate of 4D-HyCoSy to assess the tubal fimbria patency was 94.3％,with the sensitivity of 90.1％ and specificity of 94.1 ％.Imaging results showed that the obstruction at tubal fimbria,uncircle-like wrapping contrast medium can be seen around ovary accounted for 80％.The patent fallopian tube fimbria,circle-like wrapping of contrast medium can be observed around ovary accounted for 85.5 ％.Conclusions The combination of TVS 4D-HyCoSy with uterine tubal liquid poking is highly in accordance with LPC by providing real-time dynamic visualization on overflowing of contrast medium from tubal fimbria,as well as the pelvic adhesion surrounding ovaries.The 4D-HyCoSy can be the preferred method for assessment of tubal fimbria patency and pelvic adhesion surrounding ovaries with its advantages of accuracy,non invasion and a good safety profile.
