Objective To observe the effect of quercetin on mechanical allodynia,astrocyte activation,and upregulation of pain-related transient receptor potential vanilloid 1(TRPV1)and P2X purinoceptor 3(P2X3)in mice with paclitaxel-induced peripheral neuropathy.Methods Twenty-four C57BL/6 mice were divided randomly into control,model,and model+quercetin groups(n=8 mice per group).Paclitaxel(total dose 8 mg/kg)was injected intraperitoneally into mice in the model and model+quercetin groups to establish the model.Mice in the control group were injected intraperitoneally with the same volume of vehicle.On day 8 after the first injection,mice in the model+quercetin group were injected with 60 mg/kg quercetin solution orally and mice in the other groups were injected with the same volume of vehicle.Mechanical pain was measured by the von Frey test.Activation of astrocytes in the spinal dorsal horn was detected by immunofluorescence.Expression levels of TRPV1 and P2X3 in dorsal root ganglia were detected by immunofluorescence and Western Blot.Results(1)Compared with model group,the mechanical pain of mice in model+quercetin group were relieved.(2)Compared with model group,the activation of astrocytes and the expressions of TRPV1 and P2X3 in mice of model+quercetin group were alleviated(P＜0.05).Conclusions Quercetin can significantly reduce mechanical pain in mice with paclitaxel-induced peripheral neuropathy.This mechanism maybe related to alleviating the activation of astrocytes in the spinal dorsal horn and reducing expression of TRPV1 and P2X3 in the dorsal root ganglia.

Objective To explore the lateral lymph node metastasis in patients with rectal cancer below peritoneal reflection and construct predictive models.Methods A total of 102 patients with rectal cancer be-low peritoneal reflection admitted in the hospital from January 2020 to April 2023 were selected as the re-search objects.According to the existence of lateral lymph node metastasis(LLNM),the patients were divided into metastatic group(n=31)and non-metastatic group(n=71).The general clinical data,tumor pathologi-cal features,laboratory indexes[carcinoembryonic antigen(CEA).carbohydrate antigen 199(CA199),neutro-phil/lymphocyte ratio(NLR),platelet/lymphocyte ratio(PLR),transforming growth factor(TGF)-α and TGF-β1]between the two groups were compared.The risk factors of LLNM in patients with rectal cancer be-low peritoneal reflection were screened by Spearman correlation analysis and Logistic regression analysis,and the predictive model was constructed and the efficacy of the model was evaluated.Results The mean maxi-mum tumor diameter,the short diameter of lateral lymph nodes,the proportion of poorly differentiated pa-tients and the proportion of patients with T3-T4 stage in the metastasis group were significantly higher than those in the non-metastasis group(P＜0.05).The average levels of TGF-α,TGF-β1 and NLR in the metasta-sis group were significantly higher than those in the non-metastasis group(P＜0.05).Spearman correlation a-nalysis,univariate and multivariate Logistic regression analysis showed that poor differentiation,T3-T4 stage,maximum tumor diameter,longer short diameter of lateral lymph nodes,higher levels of TGF-α,TGF-β1 and NLR were independent risk factors for LLNM in patients with rectal cancer below peritoneal reflec-tion.Receiver operating characteristic(ROC)curve analysis showed that the area under the curve(AUC)of the predictive model based on the above risk factors was 0.915(95％CI:0.847-0.984),which had high pre-dictive performance.Conclusion Patients with LLNM and rectal cancer below peritoneal reflection often have longer tumor diameter and lateral lymph node short diameter,and higher levels of TGF-α,TGF-β1 and NLR.Lateral lymph node dissection should be actively carried out for patients with above characteristics,and timely monitoring should be carried out to see if there is still lymph node metastasis after surgery,so as to provide certain clinical basis for improving the judgment of LLNM in rectal cancer below peritoneal reflection.

Objective To evaluate the apparent diffusion coefficient(ADC)values of different bone marrow infiltration patterns in multiple myeloma(MM)patients with MR whole-body diffusion weighted imaging(WB-DWI)and to determine the ADC thresholds for different bone marrow infiltration patterns.Methods Nineteen MM patients diagnosed for the first time were selected.The lesions types of each site(cervical spine,ribs,sternum,humerus,scapula,sacral spine,ilium,femur,thoracic spine,and lumbar spine)after the WB-DWI images were visually evaluated,which were divided into focal group(including focal lesion in combined focal and diffuse infiltration)[region of interest(ROI)=141],pure diffuse infiltration group(ROI=150),diffuse lesion in combined focal and diffuse infiltration group(ROI=127),"salt-and-pepper"group(ROI=54),and normal appearance group(ROI=68).ADC values were measured and compared between each group and the receiver operating characteristic(ROC)curve was drawn to distinguish different patterns of bone marrow infiltration.Results There was no statistically significant difference in ADC values between the diffuse lesion in combined focal and diffuse infiltration group and the"salt-and-pepper"group(P＞0.99),and there was statistically significant difference in ADC values between the other groups(P＜0.05).The ROC curve showed that the area under the curve(AUC)for identifying focal group and the"salt-and-pepper"group was 0.889[95％confidence interval(CI)0.844-0.934],the AUC for identifying pure diffuse infiltration group and the normal appearance group was 0.968(95％CI 0.949-0.987).ADC values were able to accurately and visually differentiate between the different patterns of bone marrow infiltration.Conclusion The ADC values can be used as a quantitative tool to objectively distinguish different bone marrow infiltration patterns in MM patients.

Prostate cancer is one of the most common malignant tumors in men and posing a serious threat to men's health. Detection methods such as prostate-specific antigen (PSA), prostate biopsy, and magnetic resonance imaging are widely used for prostate cancer screening, but they have low specificity, high cost, and significant risks. Therefore, there is an urgent need to develop highly specific, low-cost, easily obtained, stable, and reliable biomarkers, and use them as the basis to establish non-invasive screening and diagnostic methods for prostate cancer. This paper reviewed the recent advances in the use of prostate cancer biomarkers and combined detection methods for prostate cancer diagnosis and prognosis assessment and provides an in-depth analysis and comparison of different biomarkers and combined detection methods, as well as points out the directions and challenges for future research. The paper emphasizes the importance of developing efficient, cost-effective and easy-to-implement biomarkers to increase the early diagnosis rate of prostate cancer, improve patient prognosis, and reduce the waste of healthcare resources. This paper provides an important theoretical basis and technical guidance for early diagnosis, precise treatment and prognostic evaluation of prostate cancer, and has important reference value for promoting clinical research and practice of prostate cancer.
