Colorectal cancer (CRC) is one of the most prevalent malignant tumors of the digestive system worldwide, characterized by continuously rising incidence and mortality rates. Despite significant advancements in therapeutic approaches, the prognosis for advanced-stage CRC remains unsatisfactory, highlighting the urgent need to explore novel molecular mechanisms and therapeutic strategies. Ferroptosis, a form of programmed cell death driven by iron-dependent lipid peroxidation, plays a crucial role in cancer occurrence, progression, and treatment resistance. Activation of ferroptosis significantly suppresses tumor cell growth. Further investigation into the mechanisms of ferroptosis in CRC occurrence, progression, and treatment could provide valuable insights for both basic and clinical research on CRC.

Objective To construct an age prediction model for adolescents using radiomics from oral panoramic radiographs.Methods Panoramic radiographic images of 441 adolescent patients aged 11.00～13.99 years were imported into the open-source software 3D Slicer for segmentation of regions of interest(ROI).Python was used to extract all features from the ROIs of all patients.The patients were randomly divided into a training set and a test set at a ratio of 7∶3.Machine learning methods were applied to analyze the correlation between radiomics features and age characteristics to build the age prediction model.Results Out of 863 two-dimensional radiomics features,10 were selected.Three machine learning methods—support vector machine,random forest,and logistic regression—were used to train the model on the training set,and the best machine learning model was chosen.The performance of the machine learning models was evaluated using the Area Under Curve(AUC).In the test set,the AUCs for females were 0.795,0.830,and 0.795 for the three methods respectively,while for males,they were 0.830,0.864,and 0.846.Conclusion The radiomics model based on oral panoramic radiographs demonstrates good diagnostic efficacy and can be used for age prediction.

Objective:To analyze the guiding value of index of consciousness 1(IoC1) and index of consciousness 2(IoC2) in anesthesia management of laparoscopic surgery.Methods:A total of 100 elderly patients undergoing laparoscopic surgery under general anesthesia in the Beijing Coal Group General Hospital from June 2022 to October 2023 were prospectively selected as research objects, and they were divided into the observation group and the control group according to random number table method, with 50 cases in each group. The observation group used IoC1 and IoC2 to monitor and guide anesthesia management, while the control group used bispectral index (BIS) to monitor the depth of anesthesia, and combined with the experience of anesthesiologists to guide anesthesia management. The changes of vital signs of patients in the two groups were compared after calm entry (T 0), induction of anesthesia (T 1), implantation of laryngeal mask 1 min (T 2), carbon dioxide (CO 2) pneumoperitoneum 1 min (T 3), and removal of laryngeal mask 1 min (T 4). The time of resuscitation extubation, dosage of anesthetic drugs, dosage of vasoactive drugs, IoC1, IoC2 and BIS were compared between the two groups. Results:The pneumoperitoneum time and incidence of circulatory instability between the two groups had no statistical differences ( P>0.05). The time of resuscitation and extubation in the observation group was shorter than that in the control group : (8.16 ± 6.08) min vs. (13.10 ± 7.09) min, the dosage of propofol and remifentanil were lower than those in the control group : (382.10 ± 201.90) mg vs. (465.48 ± 213.51) mg, (0.81 ± 0.62) mg vs. (1.17 ± 0.55) mg, there were statistical differences ( P<0.05). The amount of ephedrine and atropine between the two groups had no statistical differences ( P>0.05). The dosage of norepinephrine in the observation group was lower than that in the control group: (106.42 ± 46.12) μg vs. (147.04 ± 51.38) μg, there was statistical difference ( P<0.05). The heart rate, mean arterial pressure (MAP) and IoC1/BIS between the two groups had no statistical differences ( P>0.05). The IoC2 values of T 0, T 1, T 2, T 3 and T 4 in the observation group were 97.46 ± 2.46, 45.28 ± 5.08, 48.64 ± 4.51, 50.44 ± 4.21 and 96.08 ± 2.69, respectively. The IoC2 value of T 3 was higher than that of T 1 and T 2 in the observation group, there were statistical differences ( P<0.05). Conclusions:The application of IoC1 and IoC2 to monitor and guide the anesthesia management of laparoscopic patients under general anesthesia makes the application of anesthetic drugs more quantitative and precise, the perioperative vital signs more stable, and the recovery time faster.

ObjectiveMyelodysplastic syndromes （MDS） is a group of clonal hematopoietic stem cell disorders，and this study aims to investigate the expression of hypoxia-inducible factor-1α（HIF-1α） in the bone marrow cells of patients with MDS and its correlation with the clinical features of MDS，the therapeutic efficacy of arsenic-containing Chineseherbal compound，and the survival prognosis. MethodAccording to the inclusion and exclusion criteria，27 MDS patients treated with arsenic-containing Chinese herbal compound in the Department of Hematology，Xiyuan Hospital，China Academy of Chinese Medical Sciences from January 2022 to September 2022 were included，and their bone marrow samples were collected by myelotomy. HIF-1α expression level in bone marrow cells was detected by real-time polymerase chain reaction （PCR） to analyze its correlation with clinical features，and logistic and Cox regression was used to analyze the risk factors affecting the efficacy and prognostic survival of MDS patients. ResultThe HIF-1α mRNA expression level was lower in bone marrow cells of MDS patients than in healthy subjects. HIF-1α was positively correlated with the degree of myelodysplasia（r=0.384，P<0.05） and bone marrow granulocytic system%（G%）（r=0.560，P<0.01）. Logistic regression showed that HIF-1α was a risk factor for the prognosis in the follow-up of the efficacy of treatment（P<0.05）and Cox regression showed that HIF-1α was an independent factor affecting the survival prognosis of MDS patients ［odds ratio（OR）=398.968，95% confidence interval（CI）（1.281，116 858.743），P<0.05］. ConclusionThe level of HIF-1α expression in bone marrow cells of MDS patients was closely related to the degree of clinical myelodysplasia and G%，and HIF-1α was a risk factor for the efficacy for and survival prognosis of MDS patients.

In response to the Opinions of the CPC Central Committee and the State Council on Promoting the Inheritance， Innovation， and Development of traditional Chinese medicine（TCM） and the spirit of the National Conference on TCM， Chinese Association of Chinese Medicine organized experts in Otorhinolaryngology Head and Neck Surgery of traditional Chinese and western medicine to discuss the clinical advantages of TCM and integrated traditional Chinese and western medicine in the treatment of allergic rhinitis （AR） and they reached a basic consensus. In recent years， the prevalence of AR has been on the rise， threatening the quality of life of patients and giving rise to a heavy burden to both the patients and the society. AR is resulted from immune imbalance rather than reduced immunity or hyperimmunity， and the imbalance is similar to the Yin-yang disharmony in TCM. In the treatment of this disease， western medicine features rapid onset. However， it is cost-intensive and causes severe surgical trauma， and the recurrence is common. TCM boasts diverse methods for AR， which can be used in all stages of this disease. It has advantages in controlling symptoms such as nasal congestion， runny nose， or dysosmia in the attack stage， preventing recurrence in the remission stage， and treating refractory AR or steroid-resistant AR. In particular， acupuncture enjoys a reputation in treatment of AR， which has been supported by evidence-based medicine and recommended by guidelines. While treating local symptoms of AR， TCM regulates the psychosomatic conditions， which facilitates chronic disease management and long-term follow-up. We should integrate the advantages of TCM and western medicine， give full play to the unique nonnegligible and irreplaceable advantages of TCM， formulate a comprehensive diagnosis and treatment scheme for learning and promotion， and summarize the research outcomes to promote the theoretical innovation of TCM on AR from the perspective of integrated traditional Chinese and western medicine.

OBJECTIVES: In this study, we explored how adiponectin mediated urotensin II (UII)‍-induced tumor necrosis factor-‍α (TNF-‍α) and α‍-smooth muscle actin (α‍-SMA) expression and ensuing intracellular signaling pathways in adventitial fibroblasts (AFs). METHODS: Growth-arrested AFs and rat tunica adventitia of vessels were incubated with UII and inhibitors of signal transduction pathways for 1‍‒‍24 h. The cells were then harvested for TNF-α receptor (TNF-‍α-R) messenger RNA (mRNA) and TNF-‍α protein expression determination by reverse transcription-polymerase chain reaction (RT-PCR) and enzyme-linked immunosorbent assay (ELISA), respectively. Adiponectin and adiponectin receptor (adipoR) expression was measured by RT-PCR, quantitative real-time PCR (qPCR), immunohistochemical analysis, and cell counting kit-8 (CCK-8) cell proliferation experiments. We then quantified TNF-α and α-SMA mRNA and protein expression levels by qPCR and immunofluorescence (IF) staining. RNA interference (RNAi) was used to explore the function of the adipoR genes. To investigate the signaling pathway, we applied western blotting (WB) to examine phosphorylation of adenosine 5'-monophosphate (AMP)‍-activated protein kinase (AMPK). In vivo, an adiponectin (APN)‍-knockout (APN-KO) mouse model mimicking adventitial inflammation was generated to measure TNF-α and α‍-SMA expression by application of qPCR and IF, with the goal of gaining a comprehensive atlas of adiponectin in vascular remodeling. RESULTS: In both cells and tissues, UII promoted TNF-α protein and TNF-α-R secretion in a dose- and time-dependent manner via Rho/protein kinase C (PKC) pathway. We detected marked expression of adipoR1, T-cadherin, and calreticulin as well as a moderate presence of adipoR2 in AFs, while no adiponectin was observed. Globular adiponectin (gAd) fostered the growth of AFs, and acted in concert with UII to induce α-SMA and TNF-α through the adipoR1/T-cadherin/calreticulin/AMPK pathway. In AFs, gAd and UII synergistically induced AMPK phosphorylation. In the adventitial inflammation model, APN deficiency up-regulated the expression of α-SMA, UII receptor (UT), and UII while inhibiting TNF-‍α expression. CONCLUSIONS From the results of our study, we can speculate that UII induces TNF‍-‍α protein and TNF-‍α‍-R secretion in AFs and rat tunica adventitia of vessels via the Rho and PKC signal transduction pathways. Thus, it is plausible that adiponectin is a major player in adventitial progression and could serve as a novel therapeutic target for cardiovascular disease administration.

OBJE CTIVE To explore the rational application and management of antibiotics in burn department of our hospital based on disease diagnosis related groups （DRGs）. METHODS Patients discharged from the burn department of our hospital from July 2020 to June 2021 were selected as the research objects to collect DRG data. The overall application of antibiotics in DRG group with more than 10 cases were analyzed ，and the application of antibiotics in typical disease groups were evaluated horizontally and vertically. RESULTS Among 3 732 discharged cases in the burn department of our hospital ，a total of 3 515 cases were included in 66 DRG groups ，21 DRG groups of which were included in the study. Among 21 DRG groups ，the maximum antibiotics use density （AUD）of antibiotics was 102.20 DDDs/（100 person·d）in AH 11 group，the utilization ratio of antibiotics was 100％，and the combined use rate of antibiotics was 81.82％；case-mix index （CMI）value was 11.49. The minimum AUD was 1.01 DDDs/（100 person·d）in XR 19 group，the utilization ratio of antibiotics was 5.06％，and the combined use rate of antibiotics was 0；CMI value was 0.81. Within the same core group ，AUD increased with the increase of CMI. The horizontal comparison and analysis of WB 11 group showed that there was a large gap in AUD among different physicians. The vertical comparison of AUD in WB11 group showed relatively small changes over time. CONCLUSIONS The horizontal and vertical evaluation of antibiotics based on DRGs can provide new clues for the control of antibiotics and help to realize the fine specialized management of antibiotics.
