Objective:To compare minimally invasive surgery with traditional open surgery, analyze the current application status of health economic evaluations in the treatment of digestive tract cancers, such as esophageal cancer, gastric cancer, and colorectal cancer by minimally invasive surgery and provide evidence for the rational selection of clinical treatment, alleviation of disease-related economic burdens, and rational allocation of healthcare resources.Methods:By using five databases, i.e. China National Knowledge Infrastructure, Wanfang data, Chinese Biomedical Literature Database, PubMed, and Embase, a database was established to retrieve all the papers about health economic studies of minimally invasive surgery for esophageal cancer, gastric cancer, and colorectal cancer published until December 31, 2023. Literature was analyzed by using software NoteExpress 3.8, and data were processed using Excel 2021. The quality of included papers was evaluated using the CHEERS 2022 checklist, and Meta-analysis was conducted by using software Stata 17.0.Results:A total of 10 919 relevant papers were retrieved, and 59 studies were included. Only 14 studies (23.7%) used standard health economic evaluation methods. Meta-analysis results revealed no significant differences in direct medical expenditure and total expenditure between minimally invasive surgery and open surgery. However, the expenditure for minimally invasive surgery exhibited a significant increase [mean difference ( MD)=5 973.12 yuan, P<0.001], while hospital stay and indirect expenditure significantly decreased ( MD: -4.85 days and -733.79 yuan, P<0.001). In China, for gastric cancer, the direct medical expenditure of endoscopic surgery was lower than that of open surgery ( MD=-33 000.00 yuan) with no significant difference ( P<0.001). In colorectal cancer cases, the direct medical and surgical expenditures for laparoscopic surgery were higher than those for open surgery ( MD: 4 277.94 yuan and 4 267.80 yuan, P<0.001), while the indirect and total medical expenditures decreased ( MD: -768.34 yuan and -159.10 yuan). Hospital stays in patients who had minimally invasive surgery for all three types of cancer were shorter than those who had open surgery ( P<0.001). Conclusions:In the treatment of gastrointestinal cancer, compared with open surgery, minimally invasive surgery shows higher expenditure, but has advantages, such as shorter hospital stay and lower indirect expenditure, and there were no significant differences in direct medical and total expenditures between the two approaches. When conducting health economic evaluation, factors such as postoperative complications, hospital stay, and patient's economic status should be considered for their impact on total medical expenditure. It is necessary to pay attention to the application of health economic evaluations in healthcare decision-making.

Air leak syndrome is a common and critical respiratory issue in neonates. Air leak syndrome not only affects pulmonary gas exchange but also leads to unstable hemodynamics, severe pulmonary hypertension, and other life-threatening conditions. In recent years, despite significant improvements in respiratory support concepts, equipment, and techniques, air leak syndrome remains a prevalent clinical problem, impacting neonatal prognosis and quality of life. This article summarizes the research progress on high-risk factors, early diagnosis, prevention, and treatment of air leak syndrome.

Objective:To investigate the clinical utility of functional near-infrared spectroscopy (fNIRS) in evaluating cerebral function in neonates with hypoxic-ischemic encephalopathy (HIE).Methods:This was a case-control study. Fifteen neonates with moderate to severe HIE who were admitted to the Department of Neonatal Medical Center, Children's Hospital of Fudan University from March 2023 to August 2024 and completed fNIRS testing were selected as the HIE group, and 15 full-term infants without neurological diseases and completed fNIRS testing were selected as the control group during the same period. Resting-state fNIRS data were acquired to construct cerebral functional connectivity networks and topological properties were analyzed. Statistical analyses included independent t-tests, Mann-Whitney U tests, analysis of variance, and Chi-square tests. Results:Compared with controls, the HIE group exhibited significantly reduced global functional connectivity strength [0.15 (0.05-0.26) vs. 0.24 (0.13-0.35), Z=－7.66, P<0.001]. Both groups demonstrated small-world network properties, with no intergroup difference (1.17±0.05 vs. 1.14±0.05, t=2.02, P=0.050). The HIE group showed decreased shortest path length (6.22±0.52 vs. 13.74±0.49, t=48.18, P<0.001), global efficiency (0.26±0.04 vs. 0.30±0.05, t=2.50, P=0.018) and normalized shortest path length (1.50±0.07 vs. 1.62±0.22, t=2.43, P=0.020). No differences were observed in the clustering coefficient or local efficiency between the two groups. Regional analysis revealed reduced nodal efficiency in both left (0.30±0.06 vs. 0.35±0.05, t=2.47, P=0.021) and right hemispheres (0.30±0.06 vs. 0.37±0.06, t=2.68, P=0.013) in HIE neonates compared with that of the corresponding hemispheres in the control group. The intra-group comparison showed no statistical significance in node efficiency between the left and right hemispheres (both P>0.05). Conclusion:fNIRS captures functional network signatures in HIE, demonstrating clinical potential for early detection of cerebral dysfunction in neonates with hypoxic-ischemic injury.

Chemoresistance to 5-fluorouracil (5-FU) is a significant challenge in treating colorectal cancer (CRC). Novel combined regimens to thwart chemoresistance are therefore urgently needed. Herein, we demonstrated that the combination of Avenanthramide A (AVN A) and 5-FU has significant therapeutic advantages against CRC. Mechanistically, AVN A directly binds to the S198 site of the histone lysine demethylase KDM4C to promote its degradation, which subsequently fosters H3K9me3 occupancy on the MIR17HG promoter to block its transcription and derepress Bim expression. AVN A enhanced the therapeutic efficacy of 5-FU via impairing the KDM4C/MIR17HG/GSK-3β negative feedback loop. Importantly, the clinical correlation of the KDM4C/MIR17HG/Bim signaling axis with 5-FU response was validated in the refractory CRC patients. We provide evidence for the enhanced effectiveness of 5-FU when combined with AVN A in chemoresistant xenografts, CRC organoids, and Apc ^Min/+ mouse model. Additionally, AVN A mitigated the systemic adverse effects of 5-FU. Overall, our findings demonstrate that combinatorial therapy with AVN A and 5-FU represents an appealing opportunity and highlights KDM4C/MIR17HG/GSK-3β negative feedback loop which confers therapeutically exploitable vulnerability to chemo-refractory CRC patients.

Objective:To analyze the lympho-vascular space invasion (LVSI) in different molecular subtypes of the cancer genome atlas (TCGA) molecular subtypes of endometrial cancer (EC) and to evaluate the prognostic value of LVSI in EC patients with different molecular subtypes.Methods:A total of 258 patients diagnosed EC undergoing surgery in Peking University People′s Hospital from January 2016 to June 2022 were analyzed retrospectively. Among 258 patients, 14 cases were classified as POLE-ultramutated subtype, 43 as high-microsatellite instability (MSI-H) subtype, 155 as copy-number low (CNL) subtype, and 46 as copy-number high (CNH) subtype. Fifty-four patients were positive for LVSI, while 203 tested negative.Results:(1) The incidence of LVSI was found to be highest in the CNH subtype (32.6%,15/46), followed by the MSI-H subtype (27.9%, 12/43), the CNL subtype (16.9%, 26/154), and the POLE-ultramutated subtype (1/14), with statistically significant differences ( χ2=7.79, P=0.044). (2) Staging and deep myometrial invasion were higher in the LVSI positive group than those in the LVSI negative group (all P<0.05), except for the POLE-ultramutated subtype. The grade, lymph node metastasis, and the expression of nuclear antigen associated with cell proliferation (Ki-67) were significantly higher in LVSI positive patients than those in LVSI negative EC patients with both MSI-H and CNL subtypes (all P<0.05). In CNL subtypes patients, LVSI was also associated with age, histology subtype,and progesterone receptor (PR; all P<0.05). (3) Of the 257 EC patients, 25 cases recurred during the follow-up period, with a recurrence rate of 9.7% (25/257); among them, the recurrence rate of LVSI positive patients was 22.2% (12/54), which was significantly higher than those with LVSI negative (6.4%, 13/203; χ2=12.15, P<0.001). During the follow-up period, none of the 14 patients with POLE-ultramutated had recurrence; among CNL patients, the recurrence rate was 19.2% (5/26) in LVSI positive patients, which was significantly higher than that in LVSI negative ones (5.5%, 7/128; χ2=3.94, P=0.047); where as no difference were found in both MSI-H [recurrence rates in LVSI positive and negative patients were 2/12 and 9.7% (3/31), respectively] and CNH subtype [recurrence rates between LVSI positive and negative patients were 5/15 and 9.7% (3/31), respectively] EC patients (both P>0.05). After log-rank test, the 3-year recurrence free survival (RFS) rate were significantly lower in LVSI positive patients from CNL subtype and CNH subtype than those in LVSI negative patients (CNL: 80.8% vs 94.5%; CNH: 66.7% vs 90.3%; both P<0.05). (4) Lymph node metastasis ( HR=6.93, 95% CI: 1.15-41.65; P=0.034) had a significant effect on the 3-year RFS rate of EC patients with MSI-H subtype. Multivariate analysis revealed that PR expression ( HR=0.04, 95% CI: 0.01-0.14; P<0.001) was significantly associated with the 3-year RFS rate of CNL subtype patients. Conclusions:LVSI has the highest positivity rate in CNH subtype, followed by MSI-H subtype, CNL subtype, and the lowest positivity rate in POLE-ultramutated subtype. LVSI is significantly associated with poor prognosis in CNL subtype patients and may affect the prognosis of CNH subtype patients. However, LVSI is not an independent risk factor for recurrence across all four TCGA molecular subtypes.

The enterprise master patient index is an important tool for identifying the diagnosis and treatment records of the same patient in heterogeneous medical data from multiple sources. From June to December 2021, the National Children′s Cancer Monitoring Center screened and determined the enterprise master patient index index system and its recognition logic by literature analysis and expert consultation. Based on the National Children′s Cancer surveillance Platform (hereinafter referred to as the surveillance platform), a corresponding intelligent recognition algorithm system was developed. After multiple rounds of real data verification and adjustment, a enterprise master patient index suitable for multi-source heterogeneous medical data was constructed. From January 2022 to March 2024, the intelligent recognition algorithm system had completed the recognition of 2.46 million pediatric tumor case report cards, established 0.33 million primary indexes and their unique identification codes for malignant tumor patients, and improved the data management and application efficiency of the surveillance platform. The enterprise master patient index based on surveillance platforms had played an important role in the registration and follow-up of pediatric cancer cases and related medical research, which could provide references for the construction of master indexes on other medical big data platforms in China.

Objective:To compare the patient-reported outcomes and short-term clinical outcomes between robotic-assisted and laparoscopic-assisted radical gastrectomy for locally advanced gastric cancer.Methods:This single-center prospective randomized controlled trial was conducted in the Department of Gastrointestinal Surgery, Affiliated Hospital of Qingdao University from October 2020 to August 2022. Patients with locally advanced gastric cancer who were to undergo radical gastrectomy were selected and randomly divided into two groups according to 1∶1, and received robotic surgery and laparoscopic surgery, respectively. Patient-reported outcomes and short-term clinical outcomes (including postoperative complications, surgical quality and postoperative short-term recovery) were compared between the two groups by independent sample t test, Mann-Whitney U test, repeated ANOVA, generalized estimating equation, χ2 test and Fisher′s exact test. Results:A total of 237 patients were enrolled for modified intention-to-treat analysis (120 patients in the robotic group, 117 patients in the laparoscopic group). There were 180 males and 59 females, aged (63.0±10.2) years (range: 30 to 85 years). The incidence of postoperative complications was similar between the robotic group and laparoscopic group (16.7% (20/120) vs. 15.4% (18/117), χ2=0.072, P=0.788). The robotic group had higher patient-reported outcomes scores in general health status, emotional, and social domains compared to the laparoscopic group, differences in time effect, intervention effect, and interaction effect were statistically significant (general health status: χ2 value were 275.68, 3.91, 6.38, P value were <0.01, 0.048, 0.041; emotional: χ2 value were 77.79, 6.04, 6.15, P value were <0.01, 0.014, 0.046; social: χ2 value were 148.00, 7.57, 5.98, P value were <0.01, 0.006, 0.048). However, the financial burden of the robotic group was higher, the differences in time effect, intervention effect and interaction effect were statistically significant ( χ2 value were 156.24, 4.08, 36.56, P value were <0.01, 0.043,<0.01). Conclusion:Compared to the laparoscopic group, the robotic group could more effectively relieve postoperative negative emotions and improve recovery of social function in patients.
