Objective To systematically integrate the qualitative studies on body image experience in breast cancer patients,in order to provide references for the clinical formulation of corresponding intervention programs.Methods Systematical search was conducted for qualitative studies on the body image experiences of breast cancer patients in databases including PubMed,Web of Science,Cochrane Library,CINAHL,PsycINFO,CNKI,WanFang Database,VIP and CBM.The search period was from the establishment of the database to July 2024.The quality of the literature was evaluated using the 2016 edition of the qualitative research appraisal tool from the Evidence-Based Health Care Center of the Joanna Briggs Research Institute in Australia,and the results were integrated using the pooled integration method.Results A total of 14 pieces of the literature were included,and 36 research results were extracted and summarized into 7 new categories.Totally 3 integrated results were obtained,namely the negative impact of changes in body image,patients' self-adjustment and growth,and patients' need for external support.Conclusion Breast cancer patients are plagued by multiple body images.Medical staff should pay attention to the psychological state of patients,do a good job in health education,improve the understanding and support of the society,provide targeted professional guidance,promote the psychological adaptation of patients,meet the emotional needs of patients,establish multiple support systems,and improve the body image and quality of life of patients.

With the rapid development of competitive sports, the incidence of anterior cruciate ligament (ACL) injury is on the rise. Such injuries may shorten athletes′ career and lead to other long-term adverse consequences. Although athletes generally recover well after ACL reconstruction, many still struggle to return to their pre-injury performance levels. Advances in the understanding of ACL anatomy and injury mechanisms, along with the evolution of surgical techniques and rehabilitation methods, have provided more individualized and tailored options for athletes following ACL injuries. However, there is currently no consensus in China regarding surgical and rehabilitation strategies for competitive athletes aiming to return to sports after ACL injuries. To this end, the Sports Medicine Committee of the Chinese Research Hospital Association and the Editorial Board of the Chinese Journal of Trauma jointly formulated the Expert consensus on surgical treatment and rehabilitation for competitive sports athletes returning to sports after anterior cruciate ligament injury ( version 2025), and presented 14 recommendations covering surgical indications, preoperative rehabilitation, surgical timing, surgical strategies and postoperative rehabilitation strategies, aiming to improve the surgical treatment and rehabilitation system for ACL injuries in competitive athletes and facilitate their return to high-level sports performance after injury.

Paraplegia caused by spinal cord injury is a serious neurological complication, for which surgery is currently the main treatment method. Due to different surgical approaches, patients are usually expected to maintain a passive prone position for a long time or switch between the supine and prone positions. Affected by multiple factors such as neurogenic sensory disorders, pathological changes in muscle tone and operative duration, the risk of intraoperative acquired pressure injury (IAPI) is significantly increased. Current clinical prevention strategies for IAPI in these patients predominantly focus on localized pressure relief during positioning, lacking systematic, standardized comprehensive prevention protocols or evidence-based guidelines. To address it, Department of Nursing, Orthopedics Branch, China International Exchange and Promotive Association for Medical and Health Care, Spinal Trauma Professional Committee, Orthopedics Branch, Chinese Medical Doctor Association, Nursing Group of Spine and Spinal Cord Professional Committee of Chinese Association of Rehabilitation Medicine organized experts in relevant fields to formulate Guideline for the prevention of intraoperative acquired pressure injury in paraplegic patients with spinal cord injury ( version 2025), based on evidence-based medical evidence and latest research results and clinical practice at home and abroad. Eleven recommendations were put forward from the aspects of preoperative risk assessment, intraoperative prevention strategies, postoperative handover and monitoring, and supportive mechanisms for IAPI prevention, aiming to standardize the prevention measures and management strategies of IAPI in paraplegic patients with spinal cord injury and accelerate the recovery of patients and improve the therapeutic effect.

Objective:To explore the association between oral health status, the lower respiratory tract microbiome, and the frequent acute exacerbation phenotype in chronic obstructive pulmonary disease (COPD).Methods:This cross-sectional study enrolled 39 patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD) hospitalized in the Department of Respiratory Medicine, Henan Provincial People′s Hospital between March 2021 and December 2022. Based on the number of hospitalization episodes for acute exacerbation in the past year, patients were divided into a frequent exacerbator group (≥2 times, n=28) and a non-frequent exacerbator group (<2 times, n=11). Bronchoalveolar lavage fluid (BALF) samples were collected from all subjects for metagenomic next-generation sequencing (mNGS). Oral health indicators and clinical data were also collected. Statistical analyses were performed using Spearman correlation analysis and multivariable Firth logistic regression analysis. Results:The frequent exacerbation group showed a significantly higher percentage of individuals with≥8 tooth loss compared to the non-frequent exacerbation group (96.4% vs 18.2%, P<0.001), a significantly younger age at first tooth loss in adulthood (53.96±7.30 years vs 62.10±5.80 years, P=0.003), and a significantly higher proportion of individuals who hardly brushed their teeth (50.00% vs 9.09%, P=0.038). The alpha-diversity indices of the lower respiratory tract microbiota were significantly lower in the frequent exacerbation group than in the non-frequent exacerbation group (all P<0.01). The relative abundances of Bacillota, Bacteroidota, Fusobacteriota, Streptococcus, Prevotella, Veillonella, Neisseria, Rothia, Prevotellamelaninogenica, Prevotellajejuni, Rothia mucilaginosa, Veillonella parvula, and Neisseria subflava were lower in the frequent exacerbation group (all P<0.05). In patients with AECOPD, the exacerbation frequency and the presence of ≥8 tooth loss were both negatively correlated with the Shannon index ( r=-0.854, P<0.001; r=-0.642, P<0.001, respectively). Further analysis revealed that Bacillota ( r=-0.862, P<0.001) and Streptococcus ( r=-0.814, P<0.001) were significantly negatively correlated with exacerbation frequency, while Pseudomonas was positively correlated with exacerbation frequency (all P<0.05). Bacillota ( r=0.369, P=0.021), Fusobacteriota ( r=0.368, P=0.021), and Veillonella ( r=0.379, P=0.017) were positively correlated with FEV 1% predicted. Multivariable Firth logistic regression analysis revealed that the first principal component of the microbial community ( OR=2.29, 95% CI: 1.20-11.07) and the loss of≥8 teeth ( OR=14.37, 95% CI: 1.42-482.51) were independent factors associated with frequent acute exacerbations. Conclusion:Frequent acute exacerbations of COPD are significant association with deteriorated oral health and dysbiosis of the lower respiratory tract microbiome, characterized by reduced alpha-diversity and depletion of commensal bacteria.

Objective To investigate the diagnostic value of serum bromodomain-containing pro-tein 4(BRD4)combined with gastrin-17(G-17)in Helicobacter pylori(Hp)-positive early gastric cancer.Methods A total of 88 patients with Hp-positive early gastric cancer admitted to our hospital from September 2021 to September 2023 were selected as early gastric cancer group.Meanwhile,92 patients with Hp-positive precancerous lesions and 80 patients with Hp-positive gastritis admitted dur-ing the same period were selected as precancerous lesion group and gastritis group,respectively.En-zyme-linked immunosorbent assay(ELISA)was used to detect the serum levels of BRD4 and G-17.Multivariate logistic regression analysis was performed to screen the influencing factors of Hp-positive early gastric cancer.Receiver operating characteristic(ROC)curve analysis was used to evaluate the diagnostic value of serum BRD4 and G-17 in Hp-positive early gastric cancer.Results Compared with the gastritis group,the levels of BRD4 and G-17 in the precancerous lesion group and early gastric cancer group were significantly increased(P＜0.05).Furthermore,compared with the precancerous le-sion group,the levels of BRD4 and G-17 in the early gastric cancer group were also significantly elevated(P＜0.05).The proportion of patients with a family history of gastric cancer,those who preferred hot food,cold food,or high-salt food,as well as the levels of PG Ⅱ,BRD4,and G-17 were signifi-cantly higher in the early gastric cancer group than in the non-gastric cancer group,while the level of pepsinogen(PG)Ⅰ was significantly lower(P＜0.05).Logistic regression analysis revealed that preference for hot food,high-salt food,PG Ⅱ,BRD4,G-17,and PG Ⅰ were all influencing factors for Hp-positive early gastric cancer(P＜0.05).The area under the curve(AUC)values for serum BRD4,G-17,and their combination in diagnosing Hp-positive early gastric cancer were 0.793,0.830,and 0.912,respectively.The diagnostic efficacy of the combined detection was superior to that of single detection(P＜0.05).Conclusion The serum levels of BRD4 and G-17 are elevated in patients with Hp-positive early gastric cancer,and both exhibit certain diagnostic value for Hp-positive early gastric cancer,suggesting their potential as serum biomarkers for the diagnosis of Hp-positive early gastric cancer.

Objective:To evaluate the efficacy and safety of regional citrate anticoagulation (RCA) during plasma exchange (PE) in pediatric patients.Methods:We conducted a retrospective analysis of 12 critically ill children admitted to the Pediatric Intensive Care Unit (PICU) of Jinan Children's Hospital, who underwent 28 PE sessions with RCA between December 2023 and August 2024. Clinical records were reviewed to assess bleeding events, extracorporeal circuit performance, and changes in arterial blood gas parameters, serum total calcium (Ca tot), and activated clotting time before and after treatment. Results:No patients exhibited signs of increased bleeding. In one case, the procedure was discontinued prematurely due to elevated venous pressure. A significant decrease in ionized calcium (Ca ion) was observed 0.5 hours post-treatment. At the end of PE, pH, HCO 3?, base excess (BE), lactate, PaCO 2, Ca tot, and Na + levels increased, while K + and Ca ion levels decreased, with all changes being statistically significant. Four hours post-treatment, pH, HCO 3?, BE, PaCO 2, and Na + remained elevated, whereas Ca ion, lactate, and K + returned to baseline. By 12–15 hours post-treatment, all parameters—including pH, HCO 3?, BE, PaCO 2, Na +, K +, Ca ion, and lactate—had normalized, showing no significant differences from pre-treatment levels. Conclusions:RCA provides effective extracorporeal anticoagulation during pediatric PE without increasing bleeding risk. However, metabolic complications—primarily metabolic alkalosis—are common. These disturbances typically resolve spontaneously and do not lead to severe adverse events. While no ideal anticoagulant for PE has yet been established, RCA remains a safe and effective option, particularly for pediatric patients at higher risk of bleeding.

AIM: To compare the refractive prediction accuracy of 7 intraocular lens(IOL)calculation formulas in the cataract eyes with short axial length(AL)at different corneal curvatures and anterior chamber depth(ACD), and analyze relevant influencing factors contributing to prediction errors.METHODS: A retrospective analysis was performed for 125 patients(125 eyes)with a short AL, who received cataract phacoemulsification at Shenyang He Eye Specialist Hospital from November 2020 to December 2021. According to the keratometry(Km), they were divided into low flat Km group(≤45.5 D), medium and high Km group(45.5 D

Objective:To explore the effects of polymorphic typing of methylenetetrahydrofolate reductase (MTHFR) and serum levels of homocysteine (Hcy) on spontaneous abortion in early pregnancy in patients with polycystic ovary syndrome (PCOS).Methods:PCOS women, treated in Dalian Women and Children′s Medical Center (Group) from January 2022 to January 2024 were included in the study. One hundred patients with previous spontaneous abortion in early pregnancy were selected as the observation group (abortion group), and 72 patients with one successful pregnancy were delivered as the control group. The difference between gene polymorphism and serum Hcy levels at the C677T locus of MTHFR gene between the two groups, and serum Hcy level with the occurrence of spontaneous abortion in PCOS patients.Results:The serum Hcy level was higher in the PCOS abortion group than in the control group: 14.70 (12.20, 18.75) μmol/L vs. 9.60 (7.62, 10.80) μmol/L, with a statistically significant difference ( P<0.05). Between the abortion and control groups, genotype CC: 23.00% (23/100) vs. 44.44% (32/72), CT: 49.00% (49/100) vs. 31.94% (23/72), TT: 28% (28/100) vs. 23.61% (17/72) ( χ2 = 9.24, P = 0.010). Genotype CT, genotype TT and allele T were all risk factors for spontaneous abortion in early pregnancy in PCOS patients. The Hcy level of each genotype in the abortion group was significantly higher than that of the control group, all statistically significant ( P<0.05), and alleles C and T had similar results ( P<0.01). There was a trend towards gradually increasing Hcy levels for the three genotypes in the same group (CC

Objective To explore the clinical efficacy and mechanism of Tanreqing injection on patients with acute exacerbation of chronic obstructive pulmonary disease(AECOPD)based on network pharmacology and cell experiments.Methods The 80 patients with AECOPD were divided into a control group and a combination group of 40 cases according to the random number method.Both groups were given conventional Western medicine treatment,and the combined group was treated with Tanreqing injection.The clinical efficacy of TCM,inflammatory factors and safety were compared between the two groups of patients.Databases such as TCMSP and software such as Cytoscape 3.7.0 were used to screen out the mechanism of Tanreqing injection in the treatment of AECOPD,and human bronchial epithelial cells 16HBE were used for experimental verification.Results The clinical effective of TCM in the combined group was higher than that in the control group(P<0.05).WBC,hs-CRP,IL-6 and SAA in the two groups were lower than before treatment(P<0.05),and those of the combined group were lower than control group(P<0.05).There was no statistically difference in adverse reactions between the two groups(P>0.05).Key targets such as MAPK1,IL-6,AKT1,and key pathways such as IL-17 signaling pathway and PI3K-Akt signaling pathway were obtained by network pharmacology methods.The level of MAPK1,IL-6,p-AKT/AKT and PI3K in the model group were significantly lower than the blank group(P<0.01);Compared with the model group,the expression of MAPK1,IL-6,pAKT/AKT and PI3K protein in the Tanreqing extract group significantly and dose-dependently reduced(P<0.05).Conclusion Tanreqing injection can reduce the inflammation level and improve the clinical efficacy in AECOPD patients.Its mechanism may be related to the inhibition of protein expression including IL-6,PI3K and p-AKT/AKT,and the regulation of the PI3K-Akt signaling pathway.

Objective:To investigate the current status and challenges of pediatric life support training in China and provide references for improving training quality.Methods:A cross-sectional study was conducted to collect data from pediatric life support training centers across the country，covering basic institutional information，training capacity and training faculty，training program funding，as well as existing challenges and issues.The domestic registry of training centers in 2023 was obtained through the American Heart Association's online platform.After contacting and verifying each center，an online questionnaire was distributed，and the aggregated data were statistically analyzed.Results:A total of 42 institutions participated in the survey，including 19 children's hospitals，14 general hospitals，6 maternal and child health hospitals，2 women and children’s hospitals，and 1 training institution.The distribution of training centers showed a concentration in coastal areas，with the top three provinces/municipalities being Guangdong（7/42，16.7%），Zhejiang（6/42，14.3%），and Shanghai（4/42，9.5%）.As of December 31 2023，the 42 institutions had an annual basic life support（BLS）training volume of 8 587 individuals，the median was 120 (100,200)，and an annual pediatric advanced life support（PALS）training volume of 2 448 individuals，the median was 30 (20,50).Among the 42 institutions，there were 598 BLS instructors and 306 PALS instructors.Among the surveyed institutions，24（24/42，57.1%）reported BLS instructor teams comprising fewer than 10 members，and 33（33/42，78.6%）reported PALS instructor teams comprising fewer than 10.Only 7 centers(7/42,16.7%）reported having dedicated funding support.The top three challenges were：training sessions occupying instructors’personal time（27/42，64.3%），low instructor compensation（16/42，38.1%），and issues with the data submission system（16/42，38.1%）.Conclusion:Pediatric life support training centers in China are primarily children’s hospitals，with a geographical concentration in coastal areas，which is also reflected in the distribution of training scale and instructor resources.Most centers have relatively small training scales and limited instructor capacity，with many instructors conducting training during their personal time.These issues may hinder the implementation and effectiveness of training programs.
