Objective: To improve the efficiency and standardization of preoperative anemia diagnosis and treatment by establishing a systematic intelligent management platform for preoperative anemia. Methods: A multidisciplinary collaborative model was adopted to develop a preoperative anemia management system that integrates intelligent early warning, standardized treatment pathways, and quality control. The system utilizes natural language processing technology to automatically capture laboratory data and establish evidence-based medical decision support functions. A pre-post study design was employed to compare changes in preoperative anemia screening rates, preoperative anemia intervention rates, reasonable use of iron supplements, and perioperative red blood cell transfusion rates before and after system implementation. Results: After system implementation, the standardization of anemia diagnosis and treatment significantly improved: 1) Screening effectiveness: The anemia screening rate increased to 50.00% (an increase of 27.24%); 2) Intervention effectiveness: The anemia treatment rate rose to 56.30% (an increase of 14.02%); 3) Treatment standardization: The reasonable use rate of iron supplements increased to 55.33% (an increase of 21.02%); the red blood cell transfusion rate decreased to 18.29% (a decrease of 4.07%), and the amount of red blood cell transfusions was reduced by 291 units. Conclusion: This system achieves full-process management of preoperative anemia through information technology, significantly enhancing the standardization of diagnosis and treatment as well as intervention effectiveness, providing an effective solution for perioperative anemia management.

Epigenomic imbalance drives abnormal transcriptional processes,promoting the onset and progression of cancer.Although defective gene regulation generally affects carcinogenesis and tumor suppression networks,tumor immunogenicity and immune cells involved in antitumor responses may also be affected by epigenomic changes,which may have significant implications for the development and application of epigenetic therapy,cancer immunotherapy,and their combinations.Herein,we focus on the impact of epigenetic regulation on tumor immune cell function and the role of key abnormal epigenetic processes,DNA methylation,histone post-translational modification,and chromatin structure in tumor immunogenicity,and introduce these epigenetic research methods.We emphasize the value of small-molecule inhibitors of epigenetic modulators in enhancing antitumor immune responses and discuss the challenges of developing treatment plans that combine epigenetic therapy and immuno-therapy through the complex interaction between cancer epigenetics and cancer immunology.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

There are huge differences between tumor cells and normal cells in material metabolism, and tumor cells mainly show increased anabolism, decreased catabolism, and imbalance in substance metabolism. These differences provide the necessary material basis for the growth and reproduction of tumor cells, and also provide important targets for the treatment of tumors. Ferroptosis is an iron-dependent form of cell death characterized by an imbalance of iron-dependent lipid peroxidation and lipid membrane antioxidant systems in cells, resulting in excessive accumulation of lipid peroxide, causing damage to lipid membrane structure and loss of function, and ultimately cell death. The regulation of ferroptosis involves a variety of metabolic pathways, including glucose metabolism, lipid metabolism, amino acid metabolism, nucleotide metabolism and iron metabolism. In order for tumor cells to grow rapidly, their metabolic needs are more vigorous than those of normal cells. Tumor cells are metabolically reprogrammed to meet their rapidly proliferating material and energy needs. Metabolic reprogramming is mainly manifested in glycolysis and enhancement of pentose phosphate pathway, enhanced glutamine metabolism, increased nucleic acid synthesis, and iron metabolism tends to retain more intracellular iron. Metabolic reprogramming is accompanied by the production of reactive oxygen species and the activation of the antioxidant system. The state of high oxidative stress makes tumor cells more susceptible to redox imbalances, causing intracellular lipid peroxidation, which ultimately leads to ferroptosis. Therefore, in-depth study of the molecular mechanism and metabolic basis of ferroptosis is conducive to the development of new therapies to induce ferroptosis in cancer treatment. Ferroptosis, as a regulated form of cell death, can induce ferroptosis in tumor cells by pharmacologically or genetically targeting the metabolism of substances in tumor cells, which has great potential value in tumor treatment. This article summarizes the effects of cellular metabolism on ferroptosis in order to find new targets for tumor treatment and provide new ideas for clinical treatment.

OBJECTIVE: To observe the clinical effect of acupuncture for delayed sleep-wake phase disorder (DSWPD). METHODS: A total of 84 patients with DSWPD were randomized into an observation group (42 cases, 2 cases dropped off) and a control group (42 cases, 3 cases dropped off). On the basis of sleep hygiene education, acupuncture was applied at Shenmai (BL 62), Zhaohai (KI 6), Hegu (LI 4), Taichong (LR 3), Zusanli (ST 36) and Sanyinjiao (SP 6) in the observation group, while placebo acupuncture was applied at the same acupoints in the control group. The treatment lasted for 8 weeks, once every other day, 3 times a week in the 1st to 4th weeks; once every 3 days, 2 times a week in the 5th to 8th weeks. Before and after treatment, the actigraphy (ACT) indexes of objective sleep (total time of stay in bed, total sleep time, sleep efficiency, the number of awakenings and the wake time after falling asleep) and plasma cortisol (CORT) level were observed; before and after treatment and in follow-up of 1, 3 months after treatment, the scores of morningness-eveningness questionnaire (MEQ), insomnia severity index (ISI), fatigue severity scale (FSS) and Epworth sleepiness scale (ESS) were observed in the two groups. RESULTS: Compared before treatment, the total sleep time was prolonged, the sleep efficiency was improved, the number of awakenings was reduced, and the wake time after falling asleep was shortened after treatment in the observation group (P<0.01, P<0.05), and those in the observation group after treatment were superior to the control group (P<0.01, P<0.05). Compared before treatment, the MEQ scores after treatment in both groups and in the follow-up of 1, 3 months after treatment in the observation group were increased (P<0.01), and the MEQ score of each time point after treatment in the observation group was higher than the control group (P<0.01). The scores of ISI, FSS and ESS after treatment, and the scores of ISI、ESS in follow-up of 1, 3 months after treatment in the observation group were decreased compared with those before treatment (P<0.01, P<0.05), and in the observation group, the scores of ISI, FSS and ESS of each time point after treatment were lower than those in the control group (P<0.01, P<0.05). After treatment, the plasma CORT level in the observation group was decreased compared with that before treatment and that in the control group (P<0.01, P<0.05). CONCLUSION Acupuncture can improve the sleep and wake phase of patients with DSWPD, improve sleep quality and daytime function, and its mechanism may be related to the down-regulation of plasma CORT level.

Objective:To evaluate the efficacy and safety of phacoemulsification combined with gonioscopy-assisted angle plasty (Phaco-GAAP) for primary angle closure glaucoma (PACG) with cataract.Methods:A case series study was carried out.Twenty-five eyes of 22 patients with PACG and cataract were enrolled in Beijing Tongren Hospital from April 2022 to August 2022.All of the patients received Phaco-GAAP surgery.During the operation, viscoelastic-assisted goniosynechialysis was performed at first, followed by a secondary angle plasty for residual peripheral anterior synechiae (PAS) based on the quantified assessment by gonioscopy, and the extent of PAS was recorded intraoperatively.The operated eyes were followed at 1 day, 1 week, 1 month and 3 months after surgery to evaluate intraocular pressure (IOP), PAS range, the number of anti-glaucoma drugs application, operation-related complications, and success rate.The qualified success rate was defined as medicine-controlled IOP ≤21 mmHg after surgery, and complete success rate was defined as IOP ≤21 mmHg without any anti-glaucoma medication.This study complied with the Declaration of Helsinki and was approved by the Ethics Committee of Beijing Tongren Hospital (TRECKY2021-136). Written informed consent was obtained from each patient prior to entering the research cohort.Results:The extent of PAS was [270(225, 360)°], [165(110, 215)°] and [100(35, 175)°] at preoperation, first and secondary angle plasty, respectively, showing a significant difference among them ( χ2 =40.742, P<0.001). The PAS range was significantly reduced at first angle plasty in comparison with preoperation and was significantly reduced at secondary angle plasty in comparison with at first angle plasty (both at P<0.001), and the proportion of the angle PAS range ≥180° decreased from 48% to 24% after second angle plasty.In 13 eyes finished gonioscopy, the PAS range was [240(195, 305)°], [60(25, 182.5)°], [170(120, 275)°]and [180(140, 280)°]at preoperation, at the end of operation, postoperative 1 month and 3 months, respectively, with a significant difference ( χ2 =23.631, P<0.001). The PAS range was significantly smaller at postoperative 1 month, 3 months than that at preoperation (both at P=0.004) and larger than that at the end of operation ( P=0.011, P=0.003). The IOP was (40.19±17.23), (15.80±7.98), (13.89±5.09), (12.80±3.79) and(13.24±2.78) mmHg before operation and 1 day, 1 week, 1 month and 3 months after operation, respectively, showing a significant difference ( F=44.031, P<0.001), and the IOP was significantly reduced after operation (all at P<0.001). The PAS range at the end of operation was positively correlated with preoperation ( rs=0.409, P=0.042). The complete and qualified success rates were 95.8%, 95.8% for postoperative 1 month, 95.8% and 100% for postoperative 3 months, respectively.The primary complication was intraoperative anterior chamber angle hemorrhage, with an incidence of 68%. Conclusions:Phaco-GAAP can intraoperatively quantify PAS range and guide secondary angle plasty, therefore, it is an effective and safe surgical intervention for PACG with cataract.

Objective:To explore the risk factors of recurrence after resection of thigh soft tissue malignant tumors and the evaluation of the postoperative lower limb function.Methods:A total of 211 patients who underwent thigh soft tissue malignant tumor resection in the Department of Orthopaedics of the second affiliated Hospital of Medical College of Zhejiang University from May 2011 to May 2021 were retrospectively analyzed, including 117 males and 94 females, aged 53 (43, 65) years. There were 59 cases of atypical/well-differentiated liposarcoma, 30 cases of other types of liposarcoma, 33 cases of malignant fibrous histiocytoma, 19 cases of fibrosarcoma, 12 cases of rhabdomyosarcoma, 12 cases of leiomyosarcoma, 9 cases of synovial sarcoma, and 37 cases of others. The tumor involvement of muscle, bone, blood vessel, nerve tissue and intermuscular compartment, postoperative Musculoskeletal Tumor Society (MSTS) functional score and recurrence were recorded. The relationship between anatomical structure and postoperative recurrence was analyzed by Cox logistic regression to determine risk factors; the cumulative recurrence rate of different compartment groups (medial compartment, anterior compartment, and posterior compartment) were compared; The Box plot was used to compare the postoperative function of patients with resection of different anatomical structures (e.g., vastus lateralis, biceps femoris, femur, etc.).Results:A total of 34 out of 211 patients relapsed, with a recurrence rate of 16.1%. The recurrence time ranged from 2.6 months to 91.6 months after operation, with a median recurrence time of 37.0 (18.2, 52.8) months. Three independent risk factors were found to be associated with recurrence, namely: pathological grade [ HR=3.86, 95% CI(1.75, 8.51)], involvement of vastus intermedius [ HR=3.05, 95% CI(1.53, 6.06)], and involvement of vastus medialis [ HR=3.17, 95% CI(1.56, 6.41)]. The recurrence rate of patients with anterior chamber tumor resection was 35.3%, which was higher than that of patients without tumor resection (16.2%), and the difference was statistically significant ( P=0.020). There was no significant difference in recurrence rate between patients with medial chamber tumor resection and patients without tumor resection ( P>0.05). The recurrence rate of patients with posterior compartment tumor resection was 12.3%, which was lower than that of unresectable patients (37.6%), and the difference was statistically significant ( P=0.002).The postoperative MSTS score of 167 patients averaged 26±3.2 points (9-30 points). After intraoperative resection of part of the femur, vastus intermedius, vastus medialis, and rectus femoris, the patient's function was relatively poor [corresponding median MSTS score: 25 (23, 28), 26 (24 28), 26 (24,28), 26(24, 27)]. Conclusion:The risk factors for local recurrence after resection of thigh soft tissue malignant tumors include: pathological grade of the tumor, and whether the vastus intermedius or vastus medialis is involved. Anterior compartment tumors have a higher recurrence rate after surgery. If the tumor involves the above-mentioned anatomical structures, more attention should be paid to the risk of local recurrence after surgery.
