Objective To investigate the expression characteristics of the transcription factor E2F2 in clear cell renal cell carcinoma (ccRCC), its impact on patient prognosis, and its potential role in the tumor immune microenvironment, with validation using clinical samples and functional assays. Methods RNA sequencing data and clinical information of ccRCC patients were obtained from the TCGA database; GSE53757 and GSE66272 datasets were downloaded from the GEO database as external validation cohorts. The expression difference of E2F2 between ccRCC tissue and normal tissue was compared, and the relationship between E2F2 expression and clinical pathological characteristics was analyzed. Kaplan-Meier (KM) survival analysis with log-rank test was performed to evaluate the effects of E2F2 on overall survival (OS), progression-free survival (PFS), and disease-specific survival (DSS). The prognostic efficacy of E2F2 in predicting 1-, 3- and 5-year survival was evaluated using receiver operating characteristic (ROC) curve. GSEA was performed to identify E2F2-related signaling pathways, and the ESTIMATE and CIBERSORT algorithms were used to assess the relationship between E2F2 expression level and tumor immune cell infiltration and immune microenvironment. Twenty pairs of surgically resected and pathologically confirmed ccRCC tissues and matched adjacent non-tumor tissues were collected from our hospital, and immunohistochemistry (IHC) was performed to detect the protein expression of E2F2. Human ccRCC cell line 786-O was used for functional assays;shRNA was used to knock down E2F2 expression (constructing stable shE2F2#1 and shE2F2#2 cell lines), and qRT-PCR and Western blot were performed to verify knockdown efficiency, followed by MTT, colony formation, and Transwell migration assays to evaluate the effects of E2F2 on the biological behaviors of ccRCC cells. Results E2F2 was significantly upregulated in ccRCC tissues (the same results in the verification set). Higher E2F2 expression was associated with advanced histological grade, clinical stage and higher TNM classification (P<0.05). KM analysis showed that patients in the E2F2 high-expression group had worse OS, PFS, and DSS (P=0.019, 0.036, <0.001); the ROC curves showed area under the curve (AUC) of E2F2 of predicting 1-, 3- and 5- year survival of ccRCC patients were 0.844, 0.851 and 0.815, respectively. GSEA revealed that the E2F2 low-expression group was enriched in multiple metabolism-related pathways, whereas the E2F2 high-expression group was associated with immune-related pathways. Immune analysis demonstrated that high E2F2 expression was associated with increased immune scores, increased proportion of immune cells, higher tumor mutation burden, and potentially stronger immunotherapy response. IHC results showed that the E2F2 immunoreactivity score in ccRCC tissues was significantly higher than that in adjacent non-tumor tissues (P<0.05). Functional assays indicated that E2F2 knockdown significantly inhibited the proliferation, colony formation, and migration of ccRCC cells. Conclusion E2F2 is highly expressed in ccRCC and may be involved in tumorigenesis and progression through modulation of the immune microenvironment. Its expression level is closely associated with patient prognosis, and E2F2 has the potential to serve as a prognostic biomarker and immunotherapeutic target in ccRCC.

Objective:To compare the clinical efficacy of Chevron-Akin osteotomy with cannulated compression screw and absorbable screw fixation in the treatment of moderate and severe hallux valgus.Methods:The data of 52 patients with moderate to severe hallux valgus treated in Sichuan Provincial Orthopaedic Hospital from January 2020 to December 2022 were retrospectively analyzed. According to the fixation method, they were divided into metal screw group and absorbable screw group. In the metal screw group, there were 25 cases (26 feet), 2 males (2 feet) and 23 females (24 feet), aged 36.7±4.9 years (range, 21-59 years), 12 feet on the left side, 14 feet on the right side, moderate 20 feet and severe 6 feet. There were 27 cases (29 feet) in the absorbable screw group, including 1 male (1 foot) and 26 female (28 feet), aged 34.1±5.5 years (range, 19-56 years), 16 feet on the left side, 13 feet on the right side, moderate 22 feet and severe 7 feet. The healing time and complications of osteotomy were recorded between the two groups, and the hallux valgus angle (HVA), first-second intermetatarsal angle (1-2 IMA), American Orthopaedic Foot and Ankle Society (AOFAS), hallux-metatarsophalangeal-interphalangeal joint score and visual analogue scale (VAS) for pain were compared before and after the operation.Results:All 52 patients were followed up. The follow-up time was 14.0±3.4 months (range, 11-27 months) in the metal screw group and 15.1±2.7 months (range, 13-24 months) in the absorbable screw group. In all patients, the incision healed in one stage, and no endovegetal rejection occurred. The osteotomy healing time was 3.8±0.8 months (range, 2-5 months) in the metal screw group and 3.4±1.1 months (range, 2.5-5 months) in the absorbable screw group, with no statistically significant difference ( t=1.014, P=0.417). In the metal screw group, there were symptoms of medial internal fixation irritation in 2 feet, medial osteophyte or thread knot irritation in 2 feet, and hallux valgus recurrence in 1 foot. The complication rate was 19%(5/26). In the absorbable screw group, medial osteophyte or thread knot stimulated one foot and hallux valgus recurred one foot, and the complication rate was 7%(2/29). The difference in complications between the two groups was statistically significant (χ 2=8.051, P=0.012). At 12 months after operation, for the metal screw group and the absorbable screw group, HVA (13.7°±2.1° and 12.9°±3.8°), 1-2 IMA (7.2°±1.5° and 7.8°±1.2°), AOFAS score (91.4±2.2 and 90.8±3.6 points) and VAS score (1.1±0.3 and 1.3±0.4 points), respectively, were significantly higher than those in the preoperative (HVA: 37.2°± 5.4° and 35.8°±4.7°, 1-2 IMA: 18.3°± 1.8° and 17.9°±1.7°, AOFAS score: 60.4±5.6 and 58.4±7.1 points, VAS: 6.4±0.6 and 6.8±0.4 points) improvement ( P<0.05), while there was no statistically significant difference between the two groups ( P>0.05). The incidence of complications in metal screw group was 19%(5/26), while in absorbable screw group it was 7%(2/29), with a statistically significant difference (χ 2=8.051, P=0.012). Conclusions:Both cannulated compression screw in Chevron-Akin osteotomy and absorbable screw fixation can have a good fixation effect in the treatment of moderate and severe hallux valgus. Absorbable screw fixation has the advantages of low complication rate, less interference with artifacts in later imaging examination and evaluation.

Systemic inflammation of cachexia is an important cause of high mortality of degenerative diseases such as ad-vanced cancer,and also the most important factor to aggravate the cachexia process.Systemic inflammation of cachexia has a profound impact on the proliferation and invasion of tumors and the catabolism of muscle and adipose tissue in patients with cachexia.In recent years,studies have shown that the dysfunction of gut microbiota during cachexia is an important cause of cachexia systemic inflamma-tion and a key therapeutic target.The dysfunctions of intestinal barrier mediated by gut microbiota and the translocation of bacterial tox-ins during the cachexia period are important causes of cachexia systemic inflammation.This article mainly summarized the relationship between gut microbiota and cachexia systemic inflammation,and summarized the mechanism of intestinal flora inducing cachexia sys-temic inflammation by regulating short chain fatty acids,lipopolysaccharide,flagellin,peptidoglycan and other substances,with a view to providing new ideas for the prevention and treatment of cachexia systemic inflammation from the perspective of intestinal flora.

This study established a droplet digital PCR(ddPCR)EvaGreen assay and probe methods for Schistosoma japonicum detection,and evaluated their application in detecting early infections in the S.japonicum host oncomelania and mice.Primers and corresponding probes for both ddPCR methods were designed and synthesized,and plasmids containing target sequences were constructed.The sensitivity of the two methods was tested through detection of the corresponding plasmids,and infectious and mixed oncomelania genomic DNA.Their specificity was evaluated by the detection of genomic DNA of negative oncomelania,Schistosoma mansoni,Clonorchis sinensis,Spirometra mansoni,and S.japonicum(as a positive control).The ddPCR probe method was evaluated by detection of early infection of oncomelania exposed tomiracidium with various ratios and incubation times,and the early migration and distribution of cercaria or schistosomula in mouse hosts infected with 200 cercaria via abdominal skin contact.According to standard curves constructed through the detection of plasmid serial dilutions,the regression equation for the EvaGreen assay was y=-0.839 9x+7.050 9,with a correlation coefficient R2=0.988 1,and the regression equation for the probe method was y=-1.047 5x+7.255 1,with a correlation coefficient R2=0.999 8.The lowest limit of plasmid detection with the probe method was between 38.94 cp/μL and 194.74 cp/μL.Both methods successfully detected positive reactions in the genomic DNA samples of infectious oncomelania at concentrations above 0.002 ng/μL and in the genomic DNA of each group of oncomelania mixtures.No significant differences between probe methods were observed in the detection values in the control group and the genomic DNA of negative oncomelania,S.mansoni,C.sinensis,and S.mansoni.However,the detection value of genomic DNA of negative oncomelania(291 ng/μL)with the EvaGreen assay was(20.3±4.39)cp/μL,a value significantly higher than the(1.5±0.1)cp/μL observed in the control group.For detection of early infection in oncomelania,the probe method detected Schistosoma japonicum DNA after 30 s incubation at room temperature with a≥5∶1 ratio of miracidium to oncomelania;the detection value peaked after a short time(5 min),and the peak value showed a fold increase similar to the increase in the miracidium to oncomelania ratio.Detection of early stage infection in mice with the probe method revealed that the schistosomula entered the lungs on day 2 and the liver on day 4,and continually migrated within the organs with abundant blood supply(spleen,kidney,and brain)in the first 9 days;moreover,a tendency toward ectopic parasitism was observed in the heart and pancreas on day 9,and a constantly negative control level was observed in the testes.The ddPCR probe method was more accurate and specific than the EvaGreen assay in the detection of plasmids,and infectious and mixed oncomelania,and the latter showed non-specific reactions in negative oncomelania detection.In a practical application,the probe method was demonstrated to be sensitive,to effectively reflect the early infection of oncomelania,and to reveal schistosomula migration and distribution in multiple organs of infected mice.

Turning to critical illness is a common stage of various diseases and injuries before death. Patients usually have complex health conditions, while the treatment process involves a wide range of content, along with high requirements for doctor′s professionalism and multi-specialty teamwork, as well as a great demand for time-sensitive treatments. However, this is not matched with critical care professionals and the current state of medical care in China. Telemedicine, which shortens the distance of medical professionals and the gap of disease diagnosis and treatments in various regions through electronic information, can effectively solve the current problem. Therefore, there is an urgent need to develop a standardized, high-quality visualization telemedicine round system .Therefore, experts have been organized to search domestic and foreign literature on telemedicine round for critically ill patients and to form this consensus based on clinical experiences so as to further improve the level of critical care treatments in regions.

Health think tanks serve as a crucial intellectual support for the Healthy China strategy. The authors systematically analyzed the definitions, classifications, and operational status of health think tanks, categorizing them into five types: government-affiliated think tanks, university and research institute think tanks, social think tanks, hospital think tanks, and corporate think tanks. It was indicated that current health think tanks had significant room for improvement in both quantity and influence, particularly concerning deeper integration with policy decision-making and interdisciplinary collaboration. Although these think tanks played a unique role in supporting government decision-making, issues such as lagging institutional development, insufficient collaborative effectiveness, and difficulties in translating research findings into practice remained prominent. To enhance the ability of think tanks to serve the Healthy China strategy, this study proposed strategies including strengthening top-level design, improving participation mechanisms, optimizing management and evaluation systems, establishing data-sharing platforms, and deepening collaborative governance, with the aim of fostering the healthy development of China′s health think tanks.
