OBJECTIVE Based on comment texts from the Weibo platform， this study adopts the text mining method to systematically analyze the public’s emotional attitudes and core concerns of “medical insurance reimbursement”， and explore the public’s real experiences and feedback in the implementation of the current system. METHODS With “medical insurance reimbursement” as the keyword， Python web crawler technology was used to collect Weibo comment texts from December 2023 to April 2025. Word frequency analysis， sentiment analysis， semantic network analysis and Latent Dirichlet Allocation （LDA） topic models were adopted to mine the in-depth features of comment texts and investigate the public’s concerns and emotional attitudes toward “medical insurance reimbursement”. RESULTS A total of 3 645 valid comment texts were obtained. The overall emotional of the public toward “medical insurance reimbursement” was weakly positive： 66.4% of the comments contained positive emotions， and 32.4% contained negative emotions. Semantic network analysis indicated that positive public emotions mainly centered on the achievements of medical insurance reform and the improvement of security level， while negative emotions mainly focused on reimbursement rules， economic burden and the implementation of medical insurance policies. The LDA model identified eight core themes， mainly including access of new drugs to medical insurance catalogs， medical insurance support for traditional Chinese medicine and biomedicine， disputes over medical insurance coverage of specific medical items， cross-regional medical treatment and medical insurance settlement， medical insurance reimbursement and medical burden， as well as the approval of innovative drugs and medical insurance payment. CONCLUSIONS The public generally holds a positive attitude toward “medical insurance reimbursement”， yet still has many expectations in terms of policy implementation. On the premise of guaranteeing the sustainability of medical insurance funds， it is suggested to further improve the transparency and fairness of the reimbursement process， and promote the scientific， standardized and efficient development of the medical insurance system. Meanwhile， attention should be paid to public opinion feedback on social media， and the policy communication mechanism should be strengthened， so as to enhance the public’s sense of gain and trust in the medical insurance system.

Objective:To analyze the fail mode of neoadjuvant therapy combined with surgery for locally advanced esophageal squamous cell carcinoma (ESCC) after long-term follow-up.Methods:Clinical data of consecutive 238 patients with locally advanced resectable ESCC who underwent neoadjuvant therapy combined with surgery in Zhejiang Cancer Hospital from September 2012 to October 2019 were retrospectively analyzed. The failure mode in the whole cohort was analyzed after long-term follow-up. The overall survival (OS) and disease free survival (DFS) rates were analyzed by Kaplan-Meier method. Survival differences were determined by log-rank test.Results:The pathological complete response (pCR) rate was 42.0% in 238 patients. After a median follow-up of 46.1 months, tumor progression occurred in 96 patients (40.3%), including 25 patients (10.5%) with local recurrence, 61 patients (25.6%) with distant metastases, and 10 patients (4.2%) with simultaneous local recurrence and distant metastases. The median OS and DFS were 64.7 months and 49.9 months. And the 3-, 5-, and 7-year OS and DFS rates were 70.0%, 52.8%, 36.4% and 63.5%, 42.5%, and 30.0%, respectively. The 3-, 5-, and 7-year locoregional recurrence-free survival rates and distant metastasis-free survival rates were 86.0%, 71.4%, 61.2% and 70.6%, 55.9%, 43.0%. Compared with non-pCR patients, the overall progression rate and distant metastasis rate of pCR patients were lower (26.0% vs. 50.7%, 16.0% vs. 32.6%, both P<0.05). And the 3-, 5-, and 7-year OS (83.0% vs. 60.2%, 69.7% vs. 41.7%, 50.4% vs. 27.7%, all P<0.001) and DFS rates (80.4% vs. 51.4%, 63.9% vs. 31.2%, 45.9% vs. 20.3%, all P<0.001) were significantly better in pCR patients. Conclusions:Distant metastasis is the main failure mode of patients with locally advanced ESCC after neoadjuvant therapy. Patients with postoperative pCR can achieve better long-term survival.

Objective:To study the safety and practicability of probiotics intestinal preparation combined with early enteral nutrition in perioperative period of laparoscopic rectal cancer radical proctectomy.Methods:The clinical data of 131 patients who underwent selective laparoscopic rectal cancer radical proctectomy in Shengjing Hospital of China Medical University from January to June 2018 were retrospectively analyzed. Among them, 80 patients received probiotics intestinal preparation combined with early enteral nutrition (experimental group), and 51 patients received traditional intestinal preparation and postoperative treatment (control group). The bleeding volume during operation, hospitalization expenses, first exhaust time, postoperative hospitalization time, indwelling catheter time and complications were compared between 2 groups.Results:The bleeding volume during operation, hospitalization expenses, postoperative hospitalization time in experimental group were significantly less than those in control group: (166.33 ± 15.18) ml vs. (226.47 ± 16.46) ml, (42 365 ± 3 921) yuan vs. (51 048 ± 4 772) yuan and (13.32 ± 1.03) d vs. (13.98 ± 1.29) d, and there were statistical differences ( P<0.01). There were no statistical difference in the first exhaust time, indwelling catheter time and incidence of complications between 2 groups ( P>0.05). Conclusions:The probiotics intestinal preparation combined with early enteral nutrition in perioperative period can reduce the hospitalization expenses and shorten the hospitalization time in patients undergoing laparoscopic rectal cancer radical proctectomy, which is safe and feasible.

Objective To evaluate the clinical efficacy of prophylactic cranial irradiation (PCI) in the treatment of surgically resected small cell lung cancer (SCLC).Methods Clinical data of SCLC patients undergoing radical resection surgery in Zhejiang Cancer Hospital from 2003 to 2015 were retrospectively analyzed.According to the treatment modality,all patients were allocated into the PCI and non-PCI groups.A total of 52 patients were finally included,including 19 patients in the PCI group (5 cases of stage Ⅰ,5 stage Ⅱ and 9 stage Ⅲ) and 33 in the non-PCI group (12 cases of stage Ⅰ,5 stage Ⅱ and 16 stage Ⅲ).Kaplan-Meier method was utilized for survival analysis.Cox proportional hazards model was adopted to analyze clinical prognosis.Results The median survival time was 32.9 months in the PCI group,and 20.4 months in the non-PCI group.The 2-year overall survival rate was 72％ in the PCI group,significantly higher than 38％ in the non-PCI group (P=0.023).The median brain metastasis-free survival (BMFS) was 32.5 months in the PCI group,and 17.1 months in the non-PCI group.In the PCI group,the 2-year BMFS rate was 89％,significantly better than 53％ in the non-PCI group (P=0.026).Subgroup analysis demonstrated that PCI could confer survival benefit to patients with p-stage Ⅲ (p=0.031) rather than p-stage Ⅰ (P=0.924) and Ⅱ (P=0.094) counterparts.Multivariate analysis revealed that PCI (HR=0.330,P=0.041) was an independent prognostic factor of the overall survival.Conclusions PCI can reduce thr risk of brain metastasis rate and improve the overall survival of patients with surgically resected SCLC.

Objective To explore the outcomes and prognostic effects of Ivor Lewis esophagectomy and evalue the N staging.Methods Participants comprised 1145 patients with ESCC from Jan.2004 to Dec.2013,who under-went Ivor Lewis esophagectomy.The clinicopathologic data were analyzed.Kaplan -Meier and Cox regression methods were used for survival analysis.Results The morbidity of postoperative complication was 9.15% and with 1.83% of motality.The 1 -,3 - and 5 -year survival rates were 84.2%,58.4%,47.9% respectively.The median survival time was 55 months and average survival time was (70.16 ±2.086)months.Cox model multivariate analysis was used for those of P <0.05 in single variate analysis.Univariate analysis revealed that gender(P =0.003),smoking history (P =0.013),alcohol history(P =0.017),tumor location(P =0.001),body mass index(P =0.008),tumor length (P =0.000),differentiation degree(P =0.000),numbers of metastic zones(P =0.000)of lymph node metastasis (P =0.000),depth of invasion (P =0.000),pathological staging(P =0.000),vascular tumor thrombus (P =0.000),nerve involvement(P =0.000)and postoperative adjuvant therapy(P =0.000)were influencing prognosis factors.And multivariate analysis revealed that differentiation degree(P =0.000),depth of invasion(P =0.000), numbers of metastic zones (P =0.013 )of lymph node metastasis (P =0.000)were independent risk factors. Conclusion Ivor Lewis esophagectomy was a safe and effective treatment,and tumor differentiation degree,depth of invasion,numbers and zones of lymph node metastasis were important prognostic factors.

Objective:To analyze the characteristics of regional lymph node metastasis in patients with resectable non-small cell lung cancer (NSCLC) and assess its clinical significance in surgical mediastinal lymph dissection and the target volume definition of postoperative radiotherapy. Methods:We retrospectively reviewed 810 patients with NSCLC, and analyzed the metastatic frequency of each regional lymph node station as well as the correlation between tumor location and regional lymph node metastases. Results:Re-gional lymph node metastases were significantly associated with the age of patients, histology, tumor size, and tumor location (P=0.013, 0.000, 0.009 and 0.000, respectively). Conclusion:The younger patients with left lung adenocarcinomas and large tumor size tended to regional lymph node metastases. The trend of regional lymphatic drainage in the lobes of lung occurred differently. The prior location of involved regional lymph nodes in different lobes of the NSCLC patients was as follows:The station 2-4 for right upper lobe tumors, the station 2-4 and 7 for right middle lobe tumors and right lower lobe tumors, the station 5-6 for left upper lobe tumors, and the station 5-6 and 7 for left lower lobe tumors. We should pay more attention to the regions regarding the higher frequencies of lymph node metastases, when determining the extent of lymph node dissection or delineating the target volume of postoperative radiotherapy for NSCLC patients.

Background and objective Conventional radical surgeries for lung cancer incur a large amount of trauma, thoracoscopic surgeries can reduce trauma, and hopefully improve patients’ postoperative quality of life (QOL). hTe aim of this study is to evaluate the impact of thoracoscopic radical surgeries on quality of life of patients with non-small cell lung cancer (NSCLC). Methods Use Quality of Life-Core 30 Questionnaire (QLQ-C30) which was exploited by European Organization for Research and Treatment (EORTC) and Quality of Life-Lung Cancer 13 Questionnaire (QLQ-LC13) which is the supplementary questionnaire according to the lung cancer patients to evaluate QOL of 60 NSCLC patients in thoraco-scopic surgery group and conventional surgery group from 3 days before operation to 24 weeks atfer operation. Results A total of 215 questionnaires were collected from 60 patients;25 postoperative questionnaires were not completed because patients could not be contacted for follow-up visits. QOL declined markedly in all patients at 3 days postoperatively;preoperative and 3-day postoperative global QOL scores in the conventional surgery and thoracoscopic surgery group were 87.8±10.3 vs 38.3± 13.1 (P<0.001) and 82.7±9.6 vs 56.3±14.8 (P<0.001), respectively. hTereatfer, QOL recovered gradually in all patients. Patients who underwent open surgery showed the most pronounced decline in QOL;global scores were lower in this group than in the thoracoscopic surgery group (P=0.012,9) at 3 days postoperatively and was not restored to the preoperative level at 24 weeks postoperatively (P=0.012,4). QOL declined less in patients undergoing thoracoscopic surgery, and most indices had recov-ered to preoperative levels at 24 weeks postoperatively. Conclusion With the advantages of small trauma, faster recovery and higher postoperative QOL, thoracoscopic surgery is a preferable lung cancer surgery.
