Small cell lung cancer (SCLC) is the thoracic malignant tumor and accounts for about 15% of lung malignancies and transfer often occurs by the time of diagnosis. Extensive stage-small cell lung cancer (ES-SCLC) accounts for about 2/3 of all SCLC. For many years, radiotherapy has occupied an important position in the treatment of SCLC, especially in the treatment of ES-SCLC, because SCLC is more sensitive to radiotherapy. However, in recent years, immune checkpoint inhibitor has shown more excellent antitumor activity in the treatment of ES-SCLC and become the mainstream argument for the treatment of ES-SCLC. However, will radiotherapy be buried by the times among the therapeutic approaches for ES-SCLC? In this article, we will review the clinical progress of radiotherapy, immunotherapy and combination therapy for ES-SCLC.

Objective:To explore the factors influencing adherence to voice therapy among patients with voice disorders in China. Methods:Patients with voice disorders who visited the Voice Therapy Center at Sun Yat-sen Memorial Hospital, Sun Yat-sen University, from February to May 2022 were enrolled in the study. Adherence was assessed using the URICA-Voice scale, while influencing factors were assessed through the Voice Handicap Index(VHI) scale and a general information questionnaire. Correlation analysis was conducted using univariate and multivariate logistic regression analysis. Results:A total of 247 patients were included in the study, comprising 57 males(23.08%) and 190 females(76.92%). The results revealed that: ①Female patients demonstrated higher likelihood of being in the contemplation stage(OR=0.22) compared to males. ②Patients with a monthly family income per capita>6 000 yuan were more likely to be in the contemplation stage than those with<3 000 yuan with an OR = 13.94. ③High vocal-demand occupations increased contemplation stage probability(OR=7.70) compared to moderate-demand occupations. ④Residence within 30-minute commute predicted action/maintenance stages(OR=7.14) versus≥60-minute commute. ⑤Patients whose occupations had high voice demands were more likely to be in the action and maintenance stages than those with average voice demands, with an OR of 16.20. Conclusion:Gender, monthly family income per capita, occupational voice demands, and distance to the hospital significantly impact the URICA-Voice compliance stages of patients. Patients who are female, have higher family income, have occupations with high voice demands, and live closer to the hospital exhibit higher compliance with voice training.

Objective:To assess the predictive performance of a nomogram model integrating endoscopic ultrasound(EUS)radiomic features with clinical variables for distinguishing early esophageal squamous cell carcinoma(ESCC)from non-cancerous lesions.Methods:Clinical and imaging data from 454 patients who underwent EUS for suspected esophageal malignancies were retrospectively collected in the First Affiliated Hospital of Nanjing Medical University(training cohort, n = 323)and Dongyang People's Hospital(external validation cohort, n = 131)from January 2020 to November 2023. Independent clinical predictors of early ESCC were identified using univariable and multivariable Logistic regression analyses to establish a clinical model. Pearson correlation and Least Absolute Shrinkage and Selection Operator(LASSO)algorithms were used to construct a radiomics model. A combined model integrating radiomics scores and clinical predictors was developed and visualized as a nomogram. The predictive performance of each model was assessed using the area under the ROC curve(AUC),and calibration curves were used to evaluate the model's fitting capability. Results:The training set and validation set indicated that there were statistically significant differences in age,smoking history and lesion location between the early ESCC group and the non-cancerous lesion change group(all P < 0.05). According to univariate and multivariate Logistic regression analysis,age( OR = 1.039,95% CI = 1.003–1.077, P = 0.036)and smoking( OR = 2.358,95% CI = 1.270 - 4.376, P = 0.007)were identified as independent predictors and used to develop the clinical model,with AUCs of 0.608 and 0.694 in the training and validation cohorts,respectively. Fourteen optimal radiomic features were selected to construct the radiomics model,with AUCs of 0.881 and 0.807 in the training and validation cohorts,respectively. The combined nomogram model demonstrated superior predictive performance with AUCs of 0.893 and 0.830,sensitivities of 82.5% and 79.1%,and specificities of 82.2% and 81.3% in the training and validation cohorts,respectively. Conclusions:The EUS-based nomogram model demonstrates optimal predictive performance and can serve as a non-invasive tool to assist endoscopists in distinguishing early ESCC from non-cancerous lesions.

BACKGROUND:Slow bone repair and poor bone formation quality are still problems during masquelet technique in the treatment of large segment bone defects.H-type vessels can induce osteogenesis,enhance the local angiogenesis and osteogenesis coupling,and promote bone repair.However,there are few reports on the role of H-type blood vessels in the bone induced membrane.OBJECTIVE:To construct a large segment bone defect model of SD rat tibia,observe the expression characteristics of H-type blood vessels in the bone induced membrane,then to identify the expression peak point of H-type blood vessels in the bone induced membrane and determine the optimal period of bone grafting.METHODS:Sixty SD rats were randomly divided into a control group(n=30)and a model group(n=30)by random number table method.The two groups were further divided into three subgroups at 4,6,and 8 weeks after bone cement implantation,with 10 rats in each group.A 4 mm bone defect model of the right tibia was constructed in both the control and the model groups.Polymethyl methacrylate bone cement was implanted in the model group to induce bone biomembrane formation,while bone cement was not implanted in the control group.At 4,6,and 8 weeks after bone cement implantation,6 rats were randomly selected at each time point.The bone induction membrane tissue was cut from the model group,and the non-bone soft tissue of the corresponding part was cut from the control group.The dynamic expressions of H-type blood vessels in the bone induced membrane were identified by immunofluorescence.The morphological changes of the bone induced membrane were observed by hematoxylin-eosin staining.The formation of blood vessels in the bone induced membrane was observed by angiography.The expression levels of osteoblast-specific transcription factor in the bone induced membrane were detected by immunohistochemistry.Four rats remained at each time point.In the model group,the bone induced membrane was cut open and the bone cement was removed and autologous coccyx was implanted.In the control group,autologous coccyx was implanted in the bone defect area.Micro-CT evaluation of the tibial defect was performed 8 weeks after bone grafting.RESULTS AND CONCLUSION:(1)Immunofluorescence staining showed that the expression of H-type vessels in the model group was most obvious 6 weeks after bone cement implantation,and the expression of H-type vessels in the model group at each time point after bone cement implantation was higher than that in the control group(P<0.05).(2)Hematoxylin-eosin staining and angiography showed that the number and volume of new blood vessels at each time point after bone cement implantation in the model group were greater than those in the control group(P<0.05).The order of the number and volume of new blood vessels in the model group was:8 weeks after bone cement implantation>6 weeks after bone cement implantation>4 weeks after bone cement implantation.(3)Immunohistochemical staining showed that the positive expression of osteoblast-specific transcription factors at each time point after bone cement implantation in the model group was higher than that in the control group(P<0.05),and the positive expression of osteoblast-specific transcription factors in the model group was most obvious 6 weeks after bone cement implantation.(4)Micro-CT detection showed that the bone repair effect of the three subgroups in the model group was significantly better than that of the corresponding subgroups in the control group,and the bone repair effect of the subgroup in the model group 6 weeks after bone cement implantation was better than that of the subgroups 4 and 8 weeks after bone cement implantation.The results indicate that H-type blood vessels are dynamically expressed in the bone induced membrane and reached a peak 6 weeks after bone cement implantation.Good bone repair effects can be obtained by the bone induced membrane bone grafting 6 weeks after bone cement implantation.

Objective:To explore the factors influencing the success rate of culturing patient-derived gastric and colorectal cancer organoids.Methods:From Feb 2022 to Oct 2023, 398 tumor tissue specimens from patients who underwent gastric cancer and colorectal cancer resection at the Department of Gastrointestinal Surgery, the Affiliated Hospital of Qingdao University, were used for organoid culture. The clinicopathological factors affecting the success rate of organoid culture were analyzed.Results:The overall success rate of organoid culture in this group was 75.1% (299/398), with the success rate of gastric cancer organoid culture being 79.8%(154/193) and that of colorectal cancer being 70.7% (145/205). Different clinicopathological T stage ( χ2=4.765, P<0.05),histological type ( χ2=11.248, P<0.05), and tumor regression grade (TRG) grade after neoadjuvant chemotherapy ( χ2=7.797, P<0.05) were related to the success rate of organoid culture . Multivariate analysis showed that the TRG grade was an independent influencing factor( P=0.040). For colorectal cancer, different pathological T stage ( χ2=5.108, P<0.05), histological type ( χ2=11.270, P<0.05), and TRG grade after neoadjuvant chemotherapy ( χ2=6.797, P<0.05) were related to the success rate of organoidculture . Different from gastric cancer, the results of multivariate analysis of colorectal cancer showed that the histological type was an independent influencing factor ( P=0.018). Conclusions:The pathologic T stage, histological type of tumors, and TRG of cancer patients all have a significant impact on the success rate of establishing tumor organoids. Among them, the TRG grade is an independent influencing factor for the culture of gastric cancer organoids, and the histological type is an independent influencing factor for colorectal cancer organoids.

Nonalcoholic steatohepatitis (NASH) is a chronic liver disease with the main pathological features of hepatic steatosis, inflammatory cell infiltration, and interstitial fibroplasia, and it is an important risk factor for liver fibrosis, liver cirrhosis, and hepatocellular carcinoma. NOD-like receptor protein 3 (NLRP3) inflammasome is the core of innate immunity, and the abnormal activation of NLRP3 inflammasome is closely associated with the development and progression of NASH, which involves multiple links such as inflammatory response and oxidative stress. A large number of studies have shown that the active ingredients of traditional Chinese medicine (TCM) and TCM compound prescriptions can improve oxidative stress, regulate lipid metabolism, and alleviate liver inflammation by regulating NLRP3 inflammasome. TCM treatment applied in clinical practice has achieved a good therapeutic effect, while inflammasome is one of the key pathways or targets for TCM in improving NASH. This article reviews the mechanism of action of NLRP3 inflammasome in NASH and the research advances in TCM intervention of NLRP3 inflammasome, in order to provide ideas for the clinical TCM treatment of NASH, as well as reference targets and research directions for the research and development of new TCM drugs.
